Identifying Preoperative Clinical Characteristics of Unexpected Gastrointestinal Perforation in Infants-A Retrospective Cohort Study. CHILDREN (BASEL, SWITZERLAND) 2024; 11:505. [PMID: 38790500 PMCID: PMC11119732 DOI: 10.3390/children11050505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Revised: 04/08/2024] [Accepted: 04/22/2024] [Indexed: 05/26/2024]
Abstract
BACKGROUND Infants presenting with unexpected pneumoperitoneum upon abdominal X-ray, indicating a gastrointestinal perforation (GIP), have a surgical emergency with potential morbidity and mortality. Preoperative determination of the location of perforation is challenging but will aid the surgeon in optimizing the surgical strategy, as colon perforations are more challenging than small bowel perforations. Therefore, the aim of this study is to provide an overview of preoperative patient characteristics, determine the differences between the small bowel and colon, and determine underlying causes in a cohort of infants with unexpected GIP. METHODS All infants (age ≤ 6 months) who presented at our center with unexpected pneumoperitoneum (no signs of pneumatosis before) undergoing surgery between 1996 and 2024 were retrospectively included. The differences between the location of perforation were analyzed using chi-squared and t-tests. Bonferroni correction was used to adjust for multiple tests. RESULTS In total, 51 infants presented with unexpected pneumoperitoneum at our center, predominantly male (N = 36/51) and premature (N = 40/51). Among them, twenty-six had small bowel, twenty-two colon, and three stomach perforations. Prematurity (p = 0.001), birthweight < 1000 g (p = 0.001), respiratory support (p = 0.001), and lower median arterial pH levels (p = 0.001) were more present in patients with small bowel perforation compared with colon perforations. Pneumatosis intestinalis was more present in patients with colon perforation (p = 0.004). All patients with Hirschsprung disease and cystic fibrosis had colon perforation. The final diagnoses were mainly focal intestinal perforations (N = 27/51) and necrotizing enterocolitis (N = 9/51). CONCLUSIONS Infants with unexpected GIP, birthweight < 1000 g, and prematurity have more risk for small bowel perforation. In case of colon perforation, additional screening (for Hirschsprung and cystic fibrosis) should be considered.

Management of acute and chronic pelvic sepsis after total mesorectal excision for rectal cancer-a 10-year experience of a national referral centre. Colorectal Dis 2024; 26:650-659. [PMID: 38418896 DOI: 10.1111/codi.16863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/26/2023] [Revised: 12/09/2023] [Accepted: 12/12/2023] [Indexed: 03/02/2024]
Abstract
AIM Uncontrolled pelvic sepsis following rectal cancer surgery may lead to dramatic consequences with significant impact on patients' quality of life. The aim of this retrospective observational study is to evaluate management of pelvic sepsis after total mesorectal excision for rectal cancer at a national referral centre. METHOD Referred patients with acute or chronic pelvic sepsis after sphincter preserving rectal cancer resection, with the year of referral between 2010 and 2014 (A) or between 2015 and 2020 (B), were included. The main outcome was control of pelvic sepsis at the end of follow-up, with healed anastomosis with restored faecal stream (RFS) as co-primary outcome. RESULTS In total 136 patients were included: 49 in group A and 87 in group B. After a median follow-up of 82 months (interquartile range 35-100) in group A and 42 months (interquartile range 22-60) in group B, control of pelvic sepsis was achieved in all patients who received endoscopic vacuum assisted surgical closure (7/7 and 2/2), in 91% (19/21) and 89% (31/35) of patients who received redo anastomosis (P = 1.000) and in 100% (18/18) and 95% (41/43) of patients who received intersphincteric resection (P = 1.000), respectively. Restorative procedures resulted in a healed anastomosis with RFS in 61% (17/28) of patients in group A and 68% (25/37) of patients in group B (P = 0.567). CONCLUSION High rates of success can be achieved with surgical salvage of pelvic sepsis in a dedicated tertiary referral centre, without significant differences over time. In well selected and motivated patients a healed anastomosis with RFS can be achieved in the majority.

Adjuvant Hyperthermic Intraperitoneal Chemotherapy in Patients With Locally Advanced Colon Cancer (COLOPEC): 5-Year Results of a Randomized Multicenter Trial. J Clin Oncol 2024; 42:140-145. [PMID: 37922442 DOI: 10.1200/jco.22.02644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 03/14/2023] [Accepted: 09/01/2023] [Indexed: 11/05/2023] Open
Abstract
Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.Whether adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) might prevent peritoneal metastases after curative surgery for high-risk colon cancer is an ongoing debate. This study aimed to determine 5-year oncologic outcomes of the randomized multicenter COLOPEC trial, which included patients with clinical or pathologic T4N0-2M0 or perforated colon cancer and randomly assigned (1:1) to either adjuvant systemic chemotherapy and HIPEC (n = 100) or adjuvant systemic chemotherapy alone (n = 102). HIPEC was performed using a one-time administration of oxaliplatin (460 mg/m2, 30 minutes, 42°C, concurrent fluorouracil/leucovorin intravenously), either simultaneously (9%) or within 5-8 weeks (91%) after primary tumor resection. Outcomes were analyzed according to the intention-to-treat principle. Long-term data were available of all 202 patients included in the COLOPEC trial, with a median follow-up of 59 months (IQR, 54.5-64.5). No significant difference was found in 5-year overall survival rate between patients assigned to adjuvant HIPEC followed by systemic chemotherapy or only adjuvant systemic chemotherapy (69.6% v 70.9%, log-rank; P = .692). Five-year peritoneal metastases rates were 63.9% and 63.2% (P = .907) and 5-year disease-free survival was 55.7% and 52.3% (log-rank; P = .875), respectively. No differences in quality-of-life outcomes were found. Our findings implicate that adjuvant HIPEC should still be performed in trial setting only.

Quality of life in patients with a perineal hernia. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:107114. [PMID: 37839295 DOI: 10.1016/j.ejso.2023.107114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 09/13/2023] [Accepted: 10/08/2023] [Indexed: 10/17/2023]
Abstract
INTRODUCTION Patients who develop a perineal hernia after abdominoperineal resection may experience discomfort during daily activities and urogenital dysfunction, but the impact on quality of life has never been formally assessed. MATERIALS AND METHODS Patients who underwent abdominoperineal resection for rectal cancer between 2014 and 2022 in two prospective multicenter trials were included. Primary outcome was defined as median overall scores or scores on functional and symptom scales of the following quality of life questionnaires: 5-level version of the 5-dimensional EuroQol, Short Form-36, and European Organization for Research and Treatment of Cancer QoL Questionnaire Colorectal cancer 29 and 30, Urogenital Distress Inventory-6, Incontinence Impact Questionnaire-7. RESULTS Questionnaires were available in 27 patients with a perineal hernia and 62 patients without a perineal hernia. The 5-dimensional EuroQol score was significantly lower in patients with a perineal hernia (83 vs 87, p = 0.048), which implies a reduced level of functioning. The median scores of pain-specific domains were significantly worse in patients with a perineal hernia as measured by the SF-36 (78 vs. 90, p = 0.006), the EORTC-CR29 (17 vs. 11, p=<0.001) and EORTC-C30 (17 vs. 0, p = 0.019). Also, significantly worse physical (73 vs. 100, p = 0.049) and emotional (83 vs. 100, p = 0.048) functioning based on EORTC-C30 was observed among those patients. Minimally important differences were found for role, physical and social functioning of the SF-36 and EORTC-C30. The urological function did not differ between the groups. CONCLUSION A symptomatic perineal hernia can significantly worsen quality of life on several domains, indicating the severity of this complication.

Abstract
BACKGROUND Chronic pelvic sepsis mostly originates from complicated pelvic surgery and failed interventions. This is a challenging condition that often requires extensive salvage surgery consisting of complete debridement with source control and filling of the dead space with well-vascularized tissue. OBJECTIVE This study aimed to describe the outcomes of gluteal fasciocutaneous flaps for the treatment of secondary pelvic sepsis. DESIGN Retrospective single-center cohort study. SETTINGS Tertiary referral center. PATIENTS Patients who underwent salvage surgery for secondary pelvic sepsis between 2012 and 2020 using a gluteal flap were included in this study. MAIN OUTCOME MEASURES Percentage of complete wound healing. RESULTS In total, 27 patients were included, of whom 22 underwent index rectal resection for cancer and 21 had undergone (chemo)radiotherapy. A median of 3 (interquartile range, 1-5) surgical and 1 (interquartile range, 1-4) radiological interventions preceded salvage surgery during a median period of 62 (interquartile range, 20-124) months. Salvage surgery included partial sacrectomy in 20 patients. The gluteal flap consisted of a V-Y flap in 16 patients, superior gluteal artery perforator flap in 8 patients, and a gluteal turnover flap in 3 patients. Median hospital stay was 9 (interquartile range, 6-18) days. During a median follow-up of 18 (interquartile range, 6-34) months, wound complications occurred in 41%, with a reintervention rate of 30%. The median time to wound healing was 69 (interquartile range, 33-154) days, with a complete healing rate of 89% at the end of follow-up. LIMITATIONS Retrospective design and heterogeneous patient population. CONCLUSIONS In patients undergoing major salvage surgery for chronic pelvic sepsis, the use of gluteal fasciocutaneous flaps is a promising solution because of the high success rate, limited risks, and relatively simple technique.

RECONSTRUCCIN CON COLGAJO FASCIOCUTNEO GLTEO DESPUS DE UNA CIRUGA DE RESCATE POR SEPSIS PLVICA ANTECEDENTES:La sepsis pélvica crónica esta causada principalmente por cirugías pélvicas complicadas e intervenciones fallidas. Esta es una condición desafiante que a menudo requiere una cirugía de rescate extensa que consiste en un desbridamiento completo controlando el orígen infeccioso y rellenando el espacio muerto con tejido bien vascularizado, como por ejemplo un colgajo de tejido autólogo. La pared abdominal (colgajo de recto abdominal) o la pierna (colgajo de gracilis) se utilizan principalmente como sitios donantes para esta indicación, mientras que los colgajos glúteos pueden ser alternativas atractivas.OBJETIVO:Describir los resultados de los colgajos fasciocutáneos glúteos en el tratamiento de la sepsis pélvica secundaria.DISEÑO:Estudio de cohortes retrospectivo en un solo centro.AJUSTES:Centro de referencia terciario.PACIENTES:Todos aquellos que se sometieron a cirugía de rescate por sepsis pélvica secundaria entre 2012 y 2020 utilizando un colgajo fasciocutáneo glúteo.PRINCIPALES MEDIDAS DE RESULTADO:El porcentaje de cicatrización completa de la herida.RESULTADOS:En total, se incluyeron 27 pacientes, de los cuales 22 fueron sometidos a resección rectal por cáncer indicada y 21 pacientes que habían recibido (quimio)radioterapia. Una mediana de tres (RIC 1-5) intervenciones quirúrgicas y una (RIC 1-4) intervenciones radiológicas precedieron a la cirugía de rescate durante una mediana de 62 (RIC 20-124) meses.La cirugía de rescate incluyó una resección parcial del sacro en 20 pacientes. El colgajo fasciocutáneo glúteo consistió en la confección de un colgajo en V-Y en 16 pacientes, un colgajo incluyendo la perforante de la arteria glútea superior en 8 y un colgajo de rotación de músculo glúteo en 3 pacientes.La mediana de estancia hospitalaria fue de nueve (RIC 6-18) días. Durante una mediana de seguimiento de 18 (IQR 6-34) meses, se produjeron complicaciones de la herida en el 41%, con una tasa de reintervención del 30%.La mediana de tiempo hasta la cicatrización de la herida fue de 69 (IQR 33-154) días con una tasa de cicatrización completa del 89 % al final del seguimiento cicatricial.LIMITACIONES:Diseño retrospectivo y población heterogénea de pacientes.CONCLUSIONES:En pacientes sometidos a cirugía mayor de rescate por sepsis pélvica crónica, el uso de colgajos fasciocutáneos glúteos es una solución prometedora debido a la alta tasa de éxito, los riesgos limitados y la técnica relativamente simple.

Should primary anastomosis be considered more? A retrospective analysis of anastomotic complications in young children. WORLD JOURNAL OF PEDIATRIC SURGERY 2023; 6:e000565. [PMID: 37671119 PMCID: PMC10476123 DOI: 10.1136/wjps-2023-000565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 06/26/2023] [Indexed: 09/07/2023] Open
Abstract
Objective Little is known about intestinal anastomotic leakage and stenosis in young children (≤3 years of age). The purpose of this study is to answer the following questions: (1) what is the incidence of anastomotic stenosis and leakage in infants? (2) which surgical diseases entail the highest incidence of anastomotic stenosis and leakage? (3) what are perioperative factors associated with anastomotic stenosis and leakage? Methods Patients who underwent an intestinal anastomosis during primary abdominal surgery in our tertiary referral centre between 1998 and 2018 were retrospectively included. Both general incidence and incidence per disease of anastomotic complications were determined. Technical risk factors (location and type of anastomosis, mode of suturing, and suture resorption time) were evaluated by multivariate Cox regression for anastomotic stenosis. Gender and American Society of Anaesthesiology (ASA) score of ≥III were evaluated by χ2 test for anastomotic leakage. Results In total, 477 patients underwent an anastomosis. The most prominent diseases are intestinal atresia (30%), Hirschsprung's disease (29%), and necrotizing enterocolitis (14%). Anastomotic stenosis developed in 7% (34/468) of the patients with highest occurrence in necrotizing enterocolitis (14%, 9/65). Colonic anastomosis was associated with an increased risk of anastomotic stenosis (hazard ratio (HR) =3.6, 95% CI 1.8 to 7.5). No technical features (type of anastomosis, suture resorption time and mode of suturing) were significantly associated with stenosis development. Anastomotic leakage developed in 5% (22/477) of the patients, with the highest occurrence in patients with intestinal atresia (6%, 9/143). An ASA score of ≥III (p=0.03) and male gender (p=0.03) were significantly associated with anastomotic leakage. Conclusions Both anastomotic stenosis and leakage are major surgical complications. Identifying more patient specific factors can result in better treatment selection, which should not solely be based on the type of disease.

Cardiac anomalies in children with congenital duodenal obstruction: a systematic review with meta-analysis. Pediatr Surg Int 2023; 39:160. [PMID: 36967411 PMCID: PMC10040397 DOI: 10.1007/s00383-023-05449-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/16/2023] [Indexed: 03/28/2023]
Abstract
BACKGROUND Cardiac anomalies occur frequently in patients with congenital duodenal obstruction (DO). However, the exact occurrence and the type of associated anomalies remain unknown. Therefore, the aim of this systematic review is to aggregate the available literatures on cardiac anomalies in patients with DO. METHODS In July 2022, a search was performed in PubMed and Embase.com. Studies describing cardiac anomalies in patients with congenital DO were considered eligible. Primary outcome was the pooled percentage of cardiac anomalies in patients with DO. Secondary outcomes were the pooled percentages of the types of cardiac anomalies, type of DO, and trisomy 21. A meta-analysis was performed to pool the reported data. RESULTS In total, 99 publications met our eligibility data, representing 6725 patients. The pooled percentage of cardiac anomalies was 29% (95% CI 0.26-0.32). The most common cardiac anomalies were persistent foramen ovale 35% (95% CI 0.20-0.54), ventricular septal defect 33% (95% CI 0.24-0.43), and atrial septal defect 33% (95% CI 0.26-0.41). The most prevalent type of obstruction was type 3 (complete atresias), with a pooled percentage of 54% (95% CI 0.48-0.60). The pooled percentage of Trisomy 21 in patients with DO was 28% (95% CI 0.26-0.31). CONCLUSION This review shows cardiac anomalies are found in one-third of the patients with DO regardless of the presence of trisomy 21. Therefore, we recommend that patients with DO should receive preoperative cardiac screening. LEVEL OF EVIDENCE II.

Routine contrast enema prior to stoma reversal seems only required following treatment for necrotizing enterocolitis: An evaluation of the diagnostic accuracy of the contrast enema. J Pediatr Surg 2023; 58:440-444. [PMID: 35871857 DOI: 10.1016/j.jpedsurg.2022.06.013] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2022] [Revised: 06/05/2022] [Accepted: 06/20/2022] [Indexed: 02/03/2023]
Abstract
INTRODUCTION Contrast enemas are often made prior to stoma reversal in order to detect distal intestinal strictures distal of the stoma. If untreated these strictures can cause obstruction which might necessitate redo-surgery. However, the value of contrast enemas is unclear. Therefore, we aim to evaluate the contrast enema's diagnostic accuracy in detecting strictures in children with a stoma. METHODS Young children (≤3 years) treated with a stoma between 1998 and 2018 were retrospectively included. The STARD criteria were followed. Patients treated for anorectal malformations and those that died before stoma reversal were excluded. Surgical identification of strictures during reversal or redo-surgery within three months was used as gold standard. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and area under the curve (AUC) reflected diagnostic accuracy. RESULTS In 224 included children, strictures were found during reversal in 10% of which 95% in patients treated for necrotizing enterocolitis. Contrast enema was performed in 68% of all patients and detected 92% of the strictures. In the overall cohort, the sensitivity was 100%, specificity 98%, PPV 88% and NPV 100% whilst the AUC was 0.98. In patients treated for NEC, the sensitivity was 100%, specificity 97%, PPV 88% and NPV 100% whilst the AUC was 0.98. CONCLUSION Strictures prior to stoma reversal seem to be mainly identified in patients treated for NEC and not in other diseases necessitating a stoma. Moreover, the contrast enema shows excellent diagnostic accuracy in detecting these strictures. For this reason we advise to only perform contrast enemas in patients treated for NEC.

Abstract
AIM The aim of this systematic review was to analyse recurrence rates after different surgical techniques for perineal hernia repair. METHOD All original studies (n ≥ 2 patients) reporting recurrence rates after perineal hernia repair after abdominoperineal resection (APR) were included. The electronic database PubMed was last searched in December 2021. The primary outcome was recurrent perineal hernia. A weighted average of the logit proportions was determined by the use of the generic inverse variance method and random effects model. RESULTS A total of 19 studies involving 172 patients were included. The mean age of patients was 64 ± 5.6 years and the indication for APR was predominantly cancer (99%, 170/172). The pooled percentage of recurrent perineal hernia was 39% (95% CI: 27%-52%) after biological mesh closure, 29% (95% CI: 21%-39%) after synthetic mesh closure, 37% (95% CI: 14%-67%) after tissue flap reconstruction only and 9% (95% CI: 1%-45%) after tissue flap reconstruction combined with mesh. CONCLUSION Recurrence rates after mesh repair of perineal hernia are high, without a clear difference between biological and synthetic meshes. The addition of a tissue flap to mesh repair seemed to have a favourable outcome, which warrants further investigation.

Abstract
AIM This study aimed to determine the incidence, consequences and outcomes of iatrogenic urinary tract injury (IUI) during salvage surgery for pelvic sepsis. METHOD Patients who underwent salvage surgery for pelvic sepsis after prior low anterior resection or Hartmann's procedure for rectal cancer were prospectively maintained in a database between 2010 and 2020 and reviewed retrospectively. The primary endpoint was the incidence of IUI. Secondary endpoints were timing of diagnosis (intra- vs. postoperative), reinterventions related to the IUI and healing of IUI. RESULTS In total 126 consecutive patients were included, and IUI occurred in 13 patients (10%). A ureteric injury occurred in eight patients, bladder injury in four patients and a urethral injury in one patient. All patients with an IUI had radiotherapy as neoadjuvant treatment. The IUI was diagnosed postoperatively in 63% (n = 8/13) with a median duration between surgery and diagnosis of the IUI of 10 days (IQR: 6-15). The median number of reinterventions was five (range 1-31) in the group with a postoperative diagnosis and one (range 0-1) in the group with an intraoperative diagnosis. Four patients required a surgical reintervention, all concerning injuries diagnosed postoperatively. At the end of follow-up, 85% of patients (n = 11/13) had a healed IUI. CONCLUSION Iatrogenic urinary tract injury is not uncommon in salvage procedures for pelvic sepsis, even in an experienced tertiary referral centre. Most injuries were diagnosed postoperatively which affects the severity of these complications, emphasising the need to improve intraoperative diagnostic modalities.

Major stoma related morbidity in young children following stoma formation and closure: A retrospective cohort study. J Pediatr Surg 2022; 57:402-406. [PMID: 34949444 DOI: 10.1016/j.jpedsurg.2021.11.021] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/06/2021] [Revised: 11/09/2021] [Accepted: 11/17/2021] [Indexed: 11/29/2022]
Abstract
BACKGROUND Little is known about stoma related morbidity in young children. Therefore, the aim of this study is to assess major morbidity after stoma formation and stoma closure and its associated risk factors. METHODS All consecutive young children (age ≤ three years) who received a stoma between 1998 and 2018 at our tertiary referral center were retrospectively included. The incidence of major stoma related morbidity (Clavien-Dindo grade ≥III) was the primary outcome. This was separately analysed for stoma formation alone, stoma closure alone and all stoma interventions combined. Non-stoma related morbidity was excluded. Risk factors for major morbidity were identified using multivariable logistic regression analysis. RESULTS In total 336 young children were included with a median follow-up of 6 (IQR:2-11) years. Of these young children, 5% (n = 17/336) received a jejunostomy, 57% (n = 192/336) an ileostomy, and 38% (n = 127/336) a colostomy. Following stoma formation, 27% (n = 92/336) of the young children experienced major stoma related morbidity, mainly consisting of high output stoma, prolapse and stoma stenosis. The major morbidity rate was 23% (n = 66/292) following stoma closure, most commonly comprising anastomotic leakage/stenosis, incisional hernia and adhesive obstructions. For combined stoma interventions, major stoma related morbidity was 39% (n = 130/336). Ileostomy was independently associated with a higher risk of developing major morbidity following stoma formation (OR:2.5; 95%-CI:1.3-4.7) as well as following closure (OR:2.7; 95%-CI:1.3-5.8). CONCLUSIONS Major stoma related morbidity is a frequent and severe clinical problem in young children, both after stoma formation and closure. The risk of morbidity should be considered when deliberating a stoma.

BACKGROUND If a newborn does not pass the first bowel movement within 48 hours, there may be an underlying cause. We describe a rare cause of delayed meconium passage. CASE DESCRIPTION The neonate was born after a gestational age of 40 weeks and 2 days. The home birth was followed by a good start. Radiological imaging was performed due to the absence of the first stool and an increase in abdominal distention. The imaging showed an abnormal course of the colon with an sudden stop. Subsequently, surgery was conducted and an intestinal malrotation with a colonic atresia was found. During the surgery, a colonic anastomosis with a deviating loop ileostomy were constructed. The postoperative course was uneventful. CONCLUSION Delayed meconium passage has a very extensive differential diagnosis, in which an atresia of the intestine is one of the possibilities. A quick and structured approach is essential to prevent a possible blow-out of the intestine.

Systematic Review of Definitions and Outcome Measures for Postoperative Ileus and Return of Bowel Function after Abdominal Surgery in Children. Eur J Pediatr Surg 2022. [PMID: 36108645 DOI: 10.1055/s-0042-1745779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/04/2022]
Abstract
This review aims to objectify which definitions and outcome measures are used for the return of bowel function and postoperative ileus in children. PubMed and Embase were systematically searched from inception to December 17, 2020. Prospective studies conducted in children (aged 0-18 years) undergoing gastrointestinal surgery which reported on definitions and/or outcome measures for post-operative ileus or return of bowel function were evaluated. Definitions and outcome measures were extracted. From 4,027 references, 71 articles were included. From the 17 articles mentioning postoperative ileus, 8 (47%) provided a definition. In total, 34 outcome measures were used and 12 were unique. "Abdominal distension" was the most reported (41%) measure. In 41%, the outcome measures only described the return of gastric motility, while 18% described the return of intestinal motility. The return of bowel function was mentioned in 67 articles, none provided a definition. In total, 133 outcome measures were used and 37 were unique. Time to oral intake was the most reported (14%) measure. In 49%, the outcome measures only described the return of gastric motility, while 10% described the return of intestinal motility. High variation in definitions and outcome measures has limited the generalizability of research into postoperative bowel function in children. Without standardization, it will be impossible to compare research results and evaluate treatments. In children, the return of gastric motility seemingly should get more focus compared to adults. Therefore, we believe that a definition of postoperative ileus with an accompanying core outcome set, developed by a multidisciplinary team, specifically for children is required.

Adhesive small bowel obstruction following abdominal surgery in young children (≤ 3 years): A retrospective analysis of incidence and risk factors using multivariate cox regression. J Pediatr Surg 2022; 57:55-60. [PMID: 35115170 DOI: 10.1016/j.jpedsurg.2021.12.029] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 12/29/2021] [Accepted: 12/30/2021] [Indexed: 11/17/2022]
Abstract
BACKGROUND Adhesions following abdominal surgery can cause small bowel obstruction (SBO) necessitating surgery. Whilst some studies have addressed SBO in children, the incidence of SBO, the diseases that are of increased risk as well as risk factors in young children remain unclear. Therefore, this study aims to determine; (1) the general incidence of SBO in young children, (2) which diseases entail highest incidence of SBO and (3) risk factors for SBO in young children. STUDY DESIGN Young children (≤ 3 years of age) who underwent abdominal surgery in our tertiary referral centre between 1998-2018 were retrospectively included. Both general incidence and incidence per disease of SBO were determined. Independent risk factors for SBO were identified using cox-regression. RESULTS The incidence of SBO was 5% (N = 88/1931) in our cohort. Five of the SBOs developed following laparoscopic treatment. Patients treated for gastroschisis (17%,N = 9/53), necrotizing enterocolitis (8%,N = 15/188) and intestinal atresia (7%,N = 13/177) were at high risk of experiencing SBO. Diaphragmatic hernia (28%,N = 7/25) and meconium ileus (28%,N = 7/25) also showed high SBO proportions. Having a history of stoma (HR:3.2, 95%-CI:2.0-5.2), undergoing emergency surgery (HR:2.2, 95%-CI:1.3-3.7) and postoperative infections (HR:1.9, 95%-CI:1.2-3.1) were general risk factors for the development of SBO. CONCLUSION The incidence of SBO in young children seems higher than what has previously been reported in older children, which is why they should be studied separately. The incidence of SBO differs between diseases. Having a history of a stoma, emergency surgery and postoperative infections were independent risk factors for SBO development. Although less at risk, SBOs do develop after laparoscopies, which is why they should be included in more long-term follow-up studies. LEVEL OF EVIDENCE II.

Laparoscopic peritoneal lavage versus sigmoidectomy for perforated diverticulitis with purulent peritonitis: three-year follow-up of the randomised LOLA trial. Surg Endosc 2022; 36:7764-7774. [PMID: 35606544 PMCID: PMC9485102 DOI: 10.1007/s00464-022-09326-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Accepted: 05/01/2022] [Indexed: 10/31/2022]
Abstract
Abstract
Background
This study aimed to compare laparoscopic lavage and sigmoidectomy as treatment for perforated diverticulitis with purulent peritonitis during a 36 month follow-up of the LOLA trial.
Methods
Within the LOLA arm of the international, multicentre LADIES trial, patients with perforated diverticulitis with purulent peritonitis were randomised between laparoscopic lavage and sigmoidectomy. Outcomes were collected up to 36 months. The primary outcome of the present study was cumulative morbidity and mortality. Secondary outcomes included reoperations (including stoma reversals), stoma rates, and sigmoidectomy rates in the lavage group.
Results
Long-term follow-up was recorded in 77 of the 88 originally included patients, 39 were randomised to sigmoidectomy (51%) and 38 to laparoscopic lavage (49%). After 36 months, overall cumulative morbidity (sigmoidectomy 28/39 (72%) versus lavage 32/38 (84%), p = 0·272) and mortality (sigmoidectomy 7/39 (18%) versus lavage 6/38 (16%), p = 1·000) did not differ. The number of patients who underwent a reoperation was significantly lower for lavage compared to sigmoidectomy (sigmoidectomy 27/39 (69%) versus lavage 17/38 (45%), p = 0·039). After 36 months, patients alive with stoma in situ was lower in the lavage group (proportion calculated from the Kaplan–Meier life table, sigmoidectomy 17% vs lavage 11%, log-rank p = 0·0268). Eventually, 17 of 38 (45%) patients allocated to lavage underwent sigmoidectomy.
Conclusion
Long-term outcomes showed that laparoscopic lavage was associated with less patients who underwent reoperations and lower stoma rates in patients alive after 36 months compared to sigmoidectomy. No differences were found in terms of cumulative morbidity or mortality. Patient selection should be improved to reduce risk for short-term complications after which lavage could still be a valuable treatment option.

Abstract
PURPOSE This study aimed to establish the functional impact of displacement of urogenital organs after abdominoperineal resection (APR) using validated questionnaires. METHODS Patients who underwent APR for primary or recurrent rectal cancer (2001-2018) with evaluable pre- and postoperative radiological imaging and completed urinary (UDI-6, IIQ-7) and sexual questionnaires (male, IIEF; female, FSFI, FSDS-R) were included from 16 centers. Absolute displacement of the internal urethral orifice, posterior bladder wall, distal end of the prostatic urethra, and cervix were correlated to urogenital function by calculating Spearman's Rho (ρ). Median function scores were compared between minimal or substantial displacement using median split. RESULTS There were 89 male and 36 female patients included, of whom 45 and 19 were sexually active after surgery. Absolute displacement of the internal urethral orifice and posterior bladder wall was not correlated with UDI-6 in men (ρ = 0.119 and ρ = 0.022) nor in women (ρ = - 0.098 and ρ = - 0.154). In men with minimal and substantial displacement of the internal urethral orifice, median UDI-6 scores were 10 (IQR 0-22) and 17 (IQR 5-21), respectively, with corresponding scores of 25 (IQR 10-46) and 21 (IQR 16-36) in women. Displacement of the cervix and FSDS-R were correlated (ρ = 0.433) in sexually active patients. CONCLUSION This first analysis on functional impact of urogenital organ displacement after APR suggests that more displacement of the cervix might be associated with worse sexual function, while the data does not indicate any potential functional impact of bladder displacement. Studies are needed to further explore this underexposed topic.

Abstract
OBJECTIVE To determine long-term outcomes of a randomized trial (BIOPEX) comparing biological mesh and primary perineal closure in rectal cancer patients after extralevator abdominoperineal resection and preoperative radiotherapy, with a primary focus on symptomatic perineal hernia. SUMMARY BACKGROUND DATA BIOPEX is the only randomized trial in this field, which was negative on its primary endpoint (30-day wound healing). METHODS This was a posthoc secondary analysis of patients randomized in the BIOPEX trial to either biological mesh closure (n = 50; 2 dropouts) or primary perineal closure (n = 54; 1 dropout). Patients were followed for 5 years. Actuarial 5-year probabilities were determined by the Kaplan-Meier statistic. RESULTS Actuarial 5-year symptomatic perineal hernia rates were 7% (95% CI, 0-30) after biological mesh closure versus 30% (95% CI, 10-49) after primary closure (P = 0.006). One patient (2%) in the biomesh group underwent elective perineal hernia repair, compared to 7 patients (13%) in the primary closure group (P = 0.062). Reoperations for small bowel obstruction were necessary in 1/48 patients (2%) and 5/53 patients (9%), respectively (P = 0.208). No significant differences were found for chronic perineal wound problems, locoregional recurrence, overall survival, and main domains of quality of life and functional outcome. CONCLUSIONS Symptomatic perineal hernia rate at 5-year follow-up after abdominoperineal resection for rectal cancer was significantly lower after biological mesh closure. Biological mesh closure did not improve quality of life or functional outcomes.

Abstract
PURPOSE Incisional hernia (IH) is a complication following abdominal surgery extensively studied in adults but less so in infants. This study aimed to identify the incidence, high risk diseases and risk factors of IH following abdominal surgery in infants. METHODS Infants undergoing abdominal surgery before the age of three years in our tertiary centre between 1998 and 2018 were included. Patient demographics, peri‑operative details and the course during follow up were retrospectively extracted from patient records. Multivariate logistic regression was performed to identify risk factors. RESULTS The incidence of incisional hernia was 5.2% (107/2055). Necrotizing enterocolitis (12%), gastroschisis (19%), and omphalocele (17%) had the highest incidences of IH. Wound infection (OR: 5.3, 95%-CI:2.9-9.5), preterm birth (OR: 4.2, 95%-CI:2.6-6.7) and history of stoma (OR 1.7, 95%-CI:1.1-2.8) were significant risk factors for IH. Whilst age at surgery, surgical approach and total number of operations did not significantly influence IH development. The IH resolved in 15% (16/107) without surgery. CONCLUSION One in twenty infants experiences IH following abdominal surgery, which is higher than previously described. Understanding the incidence of IH and associated risk factors will allow physicians to identify infants that may be at increased risk for IH and to possibly act pre-emptively.

Abstract
AIM This study aimed to quantify displacement of urogenital organs after abdominoperineal resection (APR), and to explore patient and treatment characteristics associated with displacement. METHOD Patients from 16 centres who underwent APR for primary or recurrent rectal cancer (2001-2018) with evaluable preoperative and 6-18 months postoperative radiological imaging were included in the study. Anatomical landmarks on sagittal images were related to a coordinate system based on reference lines between fixed bony structures and absolute displacements were calculated using the Pythagorean theorem. Rotation of landmarks was measured relative to a pubic-S5 reference line. RESULTS There were 248 patients included of which 171 were men and 77 women. The median displacement of the internal urethral orifice was 25 mm in men (maximum 65), and 17 mm in women (maximum 50). Rotation of the internal urethral orifice was in a caudal direction in 160/170 (94%) of men and 65/73 (89%) of women, with a median of 32 degrees (maximum 85) and 33 degrees (maximum 83), respectively. Displacements of the posterior bladder wall, distal end of prostatic urethra and cervix were significantly correlated with the internal urethral orifice. In linear regression analysis, biological mesh reconstruction of the pelvic floor and visceral interposition were significantly associated with increased displacement of the internal urethral orifice, and female gender and any filling of the presacral space with decreased displacement. CONCLUSIONS Substantial absolute displacement and rotation of urogenital organs after APR for rectal cancer were observed, but with high variability among both men and women, and being significantly associated with reconstructive interventions.

Abstract
BACKGROUND Surgical site infections (SSI) are a frequent and significant problem understudied in infants operated for abdominal birth defects. Different forms of SSIs exist, namely wound infection, wound dehiscence, anastomotic leakage, post-operative peritonitis and fistula development. These complications can extend hospital stay, surge medical costs and increase mortality. If the incidence was known, it would provide context for clinical decision making and aid future research. Therefore, this review aims to aggregate the available literature on the incidence of different SSIs forms in infants who needed surgery for abdominal birth defects. METHOD The electronic databases Pubmed, EMBASE, and Cochrane library were searched in February 2020. Studies describing infectious complications in infants (under three years of age) were considered eligible. Primary outcome was the incidence of SSIs in infants. SSIs were categorized in wound infection, wound dehiscence, anastomotic leakage, postoperative peritonitis, and fistula development. Secondary outcome was the incidence of different forms of SSIs depending on the type of birth defect. Meta-analysis was performed pooling reported incidences in total and per birth defect separately. RESULTS 154 studies, representing 11,786 patients were included. The overall pooled percentage of wound infections after abdominal birth defect surgery was 6% (95%-CI:0.05-0.07) ranging from 1% (95% CI:0.00-0.05) for choledochal cyst surgery to 10% (95%-CI:0.06-0.15) after gastroschisis surgery. Wound dehiscence occurred in 4% (95%-CI:0.03-0.07) of the infants, ranging from 1% (95%-CI:0.00-0.03) after surgery for duodenal obstruction to 6% (95%-CI:0.04-0.08) after surgery for gastroschisis. Anastomotic leakage had an overall pooled percentage of 3% (95%-CI:0.02-0.05), ranging from 1% (95%-CI:0.00-0.04) after surgery for duodenal obstruction to 14% (95% CI:0.06-0.27) after colon atresia surgery. Postoperative peritonitis and fistula development could not be specified per birth defect and had an overall pooled percentage of 3% (95%-CI:0.01-0.09) and 2% (95%-CI:0.01-0.04). CONCLUSIONS This review has systematically shown that SSIs are common after correction for abdominal birth defects and that the distribution of SSI differs between birth defects.

Abstract
Abstract
Objectives
Ileus following surgery can arise in different forms namely as paralytic ileus, adhesive small bowel obstruction or as anastomotic stenosis. The incidences of these different forms of ileus are not well known after abdominal birth defect surgery in infants. Therefore, this review aims to estimate the incidence in general between abdominal birth defects.
Content
Studies reporting on paralytic ileus, adhesive small bowel obstruction or anastomotic stenosis were considered eligible. PubMed and Embase were searched and risk of bias was assessed. Primary outcome was the incidence of complications. A meta-analysis was performed to pool the reported incidences in total and per birth defect separately.
Summary
This study represents a total of 11,617 patients described in 152 studies of which 86 (56%) had a follow-up of at least half a year. Pooled proportions were calculated as follows; paralytic ileus: 0.07 (95%-CI, 0.05–0.11; I
2=71%, p≤0.01) ranging from 0.14 (95% CI: 0.08–0.23) in gastroschisis to 0.05 (95%-CI: 0.02–0.13) in omphalocele. Adhesive small bowel obstruction: 0.06 (95%-CI: 0.05–0.07; I
2=74%, p≤0.01) ranging from 0.11 (95% CI: 0.06–0.19) in malrotation to 0.03 (95% CI: 0.02–0.06) in anorectal malformations. Anastomotic stenosis after a month 0.04 (95%-CI: 0.03–0.06; I
2=59%, p=0.30) ranging from 0.08 (95% CI: 0.04–0.14) in gastroschisis to 0.02 (95% CI: 0.01–0.04) in duodenal obstruction. Anastomotic stenosis within a month 0.03 (95%-CI 0.01–0.10; I
2=81%, p=0.02) was reviewed without separate analysis per birth defect.
Outlook
This review is the first to aggregate the known literature in order approximate the incidence of different forms of ileus for different abdominal birth defects. We showed these complications are common and the distribution varies between birth defects. Knowing which birth defects are most at risk can aid clinicians in taking prompt action, such as nasogastric tube placement, when an ileus is suspected. Future research should focus on the identification of risk factors and preventative measures. The incidences provided by this review can be used in those studies as a starting point for sample size calculations.

Abstract
Background The aim of this study was to compare perineal wound healing between gluteal turnover flap and primary closure in patients undergoing abdominoperineal resection (APR) for rectal cancer. Methods Patients who underwent APR for primary or recurrent rectal cancer with gluteal turnover flap in two university hospitals (2016–2021) were compared to a multicentre cohort of primary closure (2000–2017). The primary endpoint was uncomplicated perineal wound healing within 30 days. Secondary endpoints were long-term wound healing, related re-interventions, and perineal herniation. The perineal hernia rate was assessed using Kaplan Meier analysis. Results Twenty–five patients had a gluteal turnover flap and 194 had primary closure. The uncomplicated perineal wound-healing rate within 30 days was 68% (17/25) after gluteal turnover flap versus 64% (124/194) after primary closure, OR 2.246; 95% CI 0.734–6.876; p = 0.156 in multivariable analysis. No major wound complications requiring surgical re-intervention occurred after flap closure. Eighteen patients with gluteal turnover flap completed 12-month follow-up, and none of them had chronic perineal sinus, compared to 6% (11/173) after primary closure (p = 0.604). The symptomatic 18-month perineal hernia rate after flap closure was 0%, compared to 9% after primary closure (p = 0.184). Conclusions The uncomplicated perineal wound-healing rate after the gluteal turnover flap and primary closure after APR is similar, and no chronic perineal sinus or perineal hernia occurred after flap closure. Future studies have to confirm potential benefits of the gluteal turnover flap.

Dorsal approach with tailored partial sacrectomy and gluteal V-Y fasciocutaneous advancement flap for the management of recurrent pelvic sepsis; case report. BMC Surg 2021; 21:194.

Abstract
Background Pelvic sepsis after surgery for rectal cancer is a severe complication, mostly originating from anastomotic leakage. Complex salvage surgery, during which an omentoplasty is often used for filling of the pelvic cavity, is seldomly required. If this fails, a symptomatic recurrent presacral abscess with a risk of progressive inflammation can develop. Such patients have often undergone multiple surgeries and have disturbed abdominal wall integrity, adhesion formation, and presence of one or two stoma(s). Subsequent salvage surgery via the conventional anterior abdominal approach is therefore less suitable. We describe three cases with a chronic presacral sinus and failure of first salvage surgery. All three patients underwent a prone only approach with tailored sacrectomy. This novel approach provided direct access to the pelvic abscess with optimal exposure for complete and safe debridement. A unilateral or bilateral gluteal V–Y fasciocutaneous advancement flap was created to completely fill the cavity with well vascularized tissue. Case presentations Three male patients of 80, 66 and 51 years of age initially underwent low anterior resection with neo-adjuvant radiotherapy for rectal cancer. The first patients underwent intersphincteric resection of the anastomosis with omentoplasty 128 months after index surgery, and second salvage surgery 2 months later. The second patient underwent abdominoperineal resection with omentoplasty for locally recurrent rectal cancer, cystoprostatectomy with revision of the omentoplasty for pelvic sepsis 100 months after index surgery, and second salvage surgery 16 months later. In the third patient, the anastomosis was dismantled with subsequent intersphincteric proctectomy and omentoplasty 20 months after index surgery, and second salvage surgery was performed 93 months later. Second salvage surgery in all three patients was indicated because of symptomatic recurrent pelvic sepsis. Second salvage surgery consisted of sacrectomy, complete debridement of the presacral area, and filling with a gluteal advancement flap. This resulted in favorable postoperative recovery with ultimate healing of the pelvic cavity. Conclusion The dorsal approach with tailored sacrectomy and gluteal V–Y advancement flap is a valuable option in highly selected patients to treat recurrent pelvic sepsis after multiple prior transabdominal interventions for chronic presacral sinus.

IMARI: multi-Interventional program for prevention and early Management of Anastomotic leakage after low anterior resection in Rectal cancer patIents: rationale and study protocol. BMC Surg 2020; 20:240. [PMID: 33059647 PMCID: PMC7565357 DOI: 10.1186/s12893-020-00890-w] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2020] [Accepted: 09/28/2020] [Indexed: 02/06/2023] Open
Abstract
Background Anastomotic leakage (AL) is still a common and feared complication after low anterior resection (LAR) for rectal cancer. The multifactorial pathophysiology of AL and lack of standardised treatment options requires a multi-modal approach to improve long-term anastomotic integrity. The objective of the IMARI-trial is to determine whether the one-year anastomotic integrity rate in patients undergoing LAR for rectal cancer can be improved using a multi-interventional program. Methods IMARI is a multicentre prospective clinical effectiveness trial, whereby current local practice (control cohort) will be evaluated, and subsequently compared to results after implementation of the multi-interventional program (intervention cohort). Patients undergoing LAR for rectal cancer will be included. The multi-interventional program includes three preventive interventions (mechanical bowel preparation with oral antibiotics, tailored full splenic flexure mobilization and intraoperative fluorescence angiography using indocyanine green) combined with a standardised pathway for early detection and active management of AL. The primary outcome is anastomotic integrity, confirmed by CT-scan at one year postoperatively. Secondary outcomes include incidence of AL, protocol compliance and association with AL, temporary and permanent stoma rate, reintervention rate, quality of life and functional outcome. Microbiome analysis will be conducted to investigate the role of the rectal microbiome in AL. In a Dutch nationwide study, the AL rate was 20%, with anastomotic integrity of 90% after one year. Based on an expected reduction of AL due to the preventive approaches of 50%, and increase of anastomotic integrity by a standardised pathway for early detection and active management of AL, we hypothesised that the anastomotic integrity rate will increase from 90 to 97% at one year. An improvement of 7% in anastomotic integrity at one year was considered clinically relevant. A total number of 488 patients (244 per cohort) are needed to detect this difference, with 80% statistical power. Discussion The IMARI-trial is designed to evaluate whether a multi-interventional program can improve long-term anastomotic integrity after rectal cancer surgery. The uniqueness of IMARI lies in the multi-modal design that addresses the multifactorial pathophysiology for prevention, and a standardised pathway for early detection and active treatment of AL.

Perineal wound closure using gluteal turnover flap or primary closure after abdominoperineal resection for rectal cancer: study protocol of a randomised controlled multicentre trial (BIOPEX-2 study). BMC Surg 2020; 20:164. [PMID: 32703182 PMCID: PMC7376711 DOI: 10.1186/s12893-020-00823-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2019] [Accepted: 07/13/2020] [Indexed: 11/13/2022] Open
Abstract
Background Abdominoperineal resection (APR) for rectal cancer is associated with high morbidity of the perineal wound, and controversy exists about the optimal closure technique. Primary perineal wound closure is still the standard of care in the Netherlands. Biological mesh closure did not improve wound healing in our previous randomised controlled trial (BIOPEX-study). It is suggested, based on meta-analysis of cohort studies, that filling of the perineal defect with well-vascularised tissue improves perineal wound healing. A gluteal turnover flap seems to be a promising method for this purpose, and with the advantage of not having a donor site scar. The aim of this study is to investigate whether a gluteal turnover flap improves the uncomplicated perineal wound healing after APR for rectal cancer. Methods Patients with primary or recurrent rectal cancer who are planned for APR will be considered eligible in this multicentre randomised controlled trial. Exclusion criteria are total exenteration, sacral resection above S4/S5, intersphincteric APR, biological mesh closure of the pelvic floor, collagen disorders, and severe systemic diseases. A total of 160 patients will be randomised between gluteal turnover flap (experimental arm) and primary closure (control arm). The total follow-up duration is 12 months, and outcome assessors and patients will be blinded for type of perineal wound closure. The primary outcome is the percentage of uncomplicated perineal wound healing on day 30, defined as a Southampton wound score of less than two. Secondary outcomes include time to perineal wound closure, incidence of perineal hernia, the number, duration and nature of the complications, re-interventions, quality of life and urogenital function. Discussion The uncomplicated perineal wound healing rate is expected to increase from 65 to 85% by using the gluteal turnover flap. With proven effectiveness, a quick implementation of this relatively simple surgical technique is expected to take place. Trial registration The trial was retrospectively registered at Clinicaltrials.gov NCT04004650 on July 2, 2019.

Abstract
PURPOSE To determine the incidence rate and identify predictive factors for interval appendectomy after non-operatively treated complicated appendicitis. METHODS Single-center retrospective cohort study conducted between January 2008 and June 2017. Adult patients with acute appendicitis were identified. Patients with complicated appendicitis initially treated non-operatively were included. Outcomes included abscess rate on imaging, results of additional imaging during follow-up, incidence rate of and surgical indications for interval appendectomy, and outcomes of histological reports. RESULTS Of all adult patients with acute appendicitis (n = 1839), 9% (170/1839) was initially treated non-operatively. Median age of these patients was 55 years (IQR 42-65) and 48.8% (83/170) were men. In 36.4% (62/170) of the patients, an appendicular abscess was diagnosed. 62.4% (106/170) did not require subsequent surgery (no interval appendectomy group) and in 37.6% (64/170), an interval appendectomy was performed (interval appendectomy group). Median follow-up was 80 weeks (17-192) and 113 weeks (34-246), respectively. Most frequent reason to perform subsequent surgery was recurrent appendicitis (45% (29/64)). Increasing age was significantly associated with a lower risk of undergoing interval appendectomy (OR 0.7; CI 0.6-0.89); p = 0.002). In the interval appendectomy group, appendicular neoplasm was found in 11% (7/64) of the patients, in contrast to 1.5% (25/1669) of the patients that had acute surgery (p < 0.001). CONCLUSIONS One out of three patients non-operatively treated for complicated appendicitis required an interval appendectomy. The incidence of appendicular neoplasms was high in these patients compared with those that had acute surgery. Therefore, additional radiological imaging following non-operatively treated complicated appendicitis is recommended.

[Dynamic compression brace for pectus carinatum: 5 years on]. NEDERLANDS TIJDSCHRIFT VOOR GENEESKUNDE 2019; 163:D3557. [PMID: 30638003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 06/09/2023]
Abstract
Pectus carinatum is a congenital chest-wall deformity with a prevalence of 0.3-0.7%. This chest-wall deformity can lead to functional, cosmetic and psychosocial problems. For many years, the only available treatment was an invasive surgical procedure. A less-invasive treatment, namely external compression of the sternum with a brace, showed disappointing results due to discomfort, a high percentage of skin complications and low compliance. The introduction of the dynamic compression brace has meant that the pressure of sternal compression can be measured and adjusted, which has improved comfort and compliance and resulted in an increased success rate of 92% and a decrease in the percentage of skin complications to just 8%. Despite the fact that wearing a compression brace for a longer period of time is not an easy undertaking for an adolescent, the use of the dynamic compression brace results in a high success rate, and is a safe and an efficient treatment.

Randomised controlled trial of transanal endoscopic microsurgery versus endoscopic mucosal resection for large rectal adenomas (TREND Study). Gut 2018; 67:837-846. [PMID: 28659349 DOI: 10.1136/gutjnl-2016-313101] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2016] [Revised: 05/02/2017] [Accepted: 05/03/2017] [Indexed: 02/06/2023]
Abstract
OBJECTIVE Non-randomised studies suggest that endoscopic mucosal resection (EMR) is equally effective in removing large rectal adenomas as transanal endoscopic microsurgery (TEM), but EMR might be more cost-effective and safer. This trial compares the clinical outcome and cost-effectiveness of TEM and EMR for large rectal adenomas. DESIGN Patients with rectal adenomas ≥3 cm, without malignant features, were randomised (1:1) to EMR or TEM, allowing endoscopic removal of residual adenoma at 3 months. Unexpected malignancies were excluded postrandomisation. Primary outcomes were recurrence within 24 months (aiming to demonstrate non-inferiority of EMR, upper limit 10%) and the number of recurrence-free days alive and out of hospital. RESULTS Two hundred and four patients were treated in 18 university and community hospitals. Twenty-seven (13%) had unexpected cancer and were excluded from further analysis. Overall recurrence rates were 15% after EMR and 11% after TEM; statistical non-inferiority was not reached. The numbers of recurrence-free days alive and out of hospital were similar (EMR 609±209, TEM 652±188, p=0.16). Complications occurred in 18% (EMR) versus 26% (TEM) (p=0.23), with major complications occurring in 1% (EMR) versus 8% (TEM) (p=0.064). Quality-adjusted life years were equal in both groups. EMR was approximately €3000 cheaper and therefore more cost-effective. CONCLUSION Under the statistical assumptions of this study, non-inferiority of EMR could not be demonstrated. However, EMR may have potential as the primary method of choice due to a tendency of lower complication rates and a better cost-effectiveness ratio. The high rate of unexpected cancers should be dealt with in further studies.

Abstract
BACKGROUND AND AIMS Large non-pedunculated rectal polyps are most commonly resected by endoscopic mucosal resection (EMR) or transanal endoscopic microsurgery (TEM). Despite pre-procedural diagnostics, unexpected rectal cancer is incidentally encountered within the resected specimen. This study aimed to compare the diagnostic assessment and procedural characteristics of lesions with and without unexpected submucosal invasion. METHODS A post-hoc analysis of a multicenter randomized trial (TREND study) was performed in which patients with a non-pedunculated rectal polyp of ≥3 cm without endoscopic suspicion of invasive growth were randomized between EMR and TEM. RESULTS Unexpected rectal cancer was detected in 13% (27/203) of patients; 15 after EMR and 12 after TEM. Most consisted of low-risk T1 cancers (78%, n = 18). There were no differences in the diagnostic assessment between lesions with and without unexpected submucosal invasion. Diagnostic biopsies revealed similar rates of high-grade dysplasia (28% [7/25] vs 18% [26/144]). When compared with EMR of adenomas, EMR procedures of unexpected cancers had a lower success rate of submucosal lifting (60% vs 93%, P < .001), were more often assessed as endoscopically incomplete (33% vs 10%, P = .01), and were more frequently terminated prematurely (60% vs 8%, P = .001). CONCLUSIONS Diagnostic assessment of large non-pedunculated rectal polyps revealed similar characteristics between unexpected cancers and adenomas. Unexpected cancers during EMR were non-lifting in 40%, endoscopically assessed as incomplete in 33%, and terminated prematurely in 60%. In treatment-naive patients, these factors should raise suspicion of malignancy and need discussion in a multidisciplinary team meeting for decision on further treatment strategies.

Redo coloanal anastomosis for anastomotic leakage after low anterior resection for rectal cancer: an analysis of 59 cases. Colorectal Dis 2018; 20:35-43. [PMID: 28795776 DOI: 10.1111/codi.13844] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/10/2017] [Accepted: 07/26/2017] [Indexed: 12/12/2022]
Abstract
AIM The construction of a new coloanal anastomosis (CAA) following anastomotic leakage after low anterior resection (LAR) is challenging. The available literature on this topic is scarce. The aim of this two-centre study was to determine the clinical success and morbidity after redo CAA. METHOD This retrospective cohort study included all patients with anastomotic leakage after LAR for rectal cancer who underwent a redo CAA between 2010 and 2014 in two tertiary referral centres. Short- and long-term morbidity were analysed, including both anastomotic leakage and permanent stoma rates on completion of follow-up. RESULTS A total of 59 patients were included, of whom 45 (76%) were men, with a mean age of 59 years (SD ± 9.4). The median interval between index and redo surgery was 14 months [interquartile range (IQR) 8-27]. The median duration of follow-up was 27 months (IQR 17-36). The most frequent complication was anastomotic leakage of the redo CAA occurring in 24 patients (41%), resulting in a median of three reinterventions (IQR 2-4) per patient. At the end of follow-up, bowel continuity was restored in 39/59 (66%) patients. Fourteen (24%) patients received a definitive colostomy and six (10%) still had a diverting ileostomy. In a multivariable model, leakage of the redo CAA was the only risk factor for permanent stoma (OR 0.022; 95% CI 0.004-0.122). CONCLUSION Redo CAA is a viable option in selected patients with persisting leakage after LAR for rectal cancer who want their bowel continuity restored. However, patients should be fully informed about the relatively high morbidity and reintervention rates.

Abstract
Background Perineal wound complications are often encountered following abdominoperineal resection (APR). Filling of the pelvic space by omentoplasty (OP) might prevent these complications, but there is scant evidence to support its routine application. Objective The aim of this study was to evaluate the impact of OP on perineal wound complications. Methods All patients undergoing APR with primary perineal closure (PPC) for non-locally advanced rectal cancer in 71 Dutch centers in 2011 were selected from a cross-sectional snapshot study. Outcomes were compared between PPC with or without OP, which was based on variability in practice among surgeons. Results Of 639 patients who underwent APR for rectal cancer, 477 had a non-locally advanced tumor and PPC was performed. Of those, 172 (36%) underwent OP. Patients with OP statistically more often underwent an extralevator approach (32% vs. 14%). Median follow-up was 41 months (interquartile range 22–47). There were no significant differences with or without OP in terms of non-healing of the perineal wound at 30 days (47% vs. 48%), non-healing at the end of follow-up (9% vs. 5%), pelvic abscess (12% vs. 13%) or re-intervention for ileus (5% vs. 3%). Perineal hernia developed significantly more often after OP (13% vs. 7%), also by multivariable analysis (odds ratio 2.61, 95% confidence interval 1.271–5.364; p = 0.009). Conclusions In contrast to previous assumptions, OP after APR with PPC appeared not to improve perineal wound healing and seemed to increase the occurrence of perineal hernia. These findings question the routine use of OP for primary filling of the pelvic space.

Abstract
Introduction Non-healing of anastomotic leakage can be observed in up to 50% after total mesorectal excision for rectal cancer. This study investigates the efficacy of early transanal closure of anastomotic leakage after pre-treatment with the Endosponge® therapy. Methods In this prospective, multicentre, feasibility study, transanal suturing of the anastomotic defect was performed after vacuum-assisted cleaning of the presacral cavity. Primary outcome was the proportion of patients with a healed anastomosis at 6 months after transanal closure. Secondary, healing at last follow-up, continuity, direct medical costs, functionality and quality of life were analysed. Results Between July 2013 and July 2015, 30 rectal cancer patients with a leaking low colorectal anastomosis were included, of whom 22 underwent neoadjuvant radiotherapy. Median follow-up was 14 (7–29) months. At 6 months, the anastomosis had healed in 16 (53%) patients. At last follow-up, anastomotic integrity was found in 21 (70%) and continuity was restored in 20 (67%) patients. Non-healing at 12 months was observed in 10/29 (34%) patients overall, and in 3/14 (21%) when therapy started within three weeks following the index operation. Major LARS was reported in 12/15 (80%) patients. The direct medical costs were €8933 (95% CI 7268–10,707) per patient. Conclusion Vacuum-assisted early transanal closure of a leaking anastomosis after total mesorectal excision with 73% preoperative radiotherapy showed that acceptable anastomotic healing rates and stoma reversal rates can be achieved. Early diagnosis and start of treatment seems crucial.

Abstract
BACKGROUND Use of topical antibiotics to improve perineal wound healing after abdominoperineal resection (APR) is controversial. The aim of this systematic review was to determine the impact of local application of gentamicin on perineal wound healing after APR. METHODS The electronic databases Pubmed, EMBASE, and Cochrane library were searched in January 2015. Perineal wound outcome was categorized as infectious complications, non-infectious complications, and primary perineal wound healing. RESULTS From a total of 582 articles, eight studies published between 1988 and 2012 were included: four randomized controlled trials (RCTs), three comparative cohort studies, and one cohort study without control group. Gentamicin was administered using sponges (n = 3), beads (n = 4), and by local injection (n = 1). There was substantial heterogeneity regarding underlying disease, definition of outcome parameters and timing of perineal wound evaluation among the included studies, which precluded meta-analysis with pooling. Regarding infectious complications, three of six evaluable studies demonstrated a positive effect of local application of gentamicin: one of four RCTs and both comparative cohort studies. Only two RCTs reported on non-infectious complications, showing no significant impact of gentamicin sponge. All three comparative cohort studies demonstrated a significantly higher percentage of primary perineal wound healing after local application of gentamicin beads, but only one out of three evaluable RCTs did show a positive effect of gentamicin sponges. CONCLUSION Currently available evidence does not support perineal gentamicin application after APR.

Abstract
AIM This study aimed to determine the clinical outcome of salvage surgery without restoring continuity for symptomatic chronic presacral sinus after low anterior resection (LAR) for rectal cancer. METHOD Out of a prospective cohort of 46 patients with chronic presacral sinus (> 1 year after LAR), 27 underwent completion proctectomy with omentoplasty between January 2005 and July 2014. RESULTS The initial treatment for rectal cancer included neoadjuvant radiotherapy in 26 (96%) patients. Besides a chronic presacral sinus, a secondary fistula was present in 15 (56%) patients. Definitive salvage surgery was performed after a median of 40 (12-350) months from the primary resection. The median hospital stay after single- and multiple-stage salvage surgery was 11 and 17 days. Postoperative complications occurred in 44% of patients. The re-intervention rate was 33% with a range of 1-10 interventions per patient. During a median follow-up of 20 (4-45) months from salvage surgery, healing of the chronic presacral sinus occurred in 78% of patients, with a healing rate after single- and multiple-stage procedures of 88% and 64% respectively (P = 0.19). CONCLUSION Patients with a symptomatic chronic presacral sinus after LAR for rectal cancer, in whom restoration of continuity is not intended, can be effectively managed by completion proctectomy with complete debridement of the sinus and fistula tracts followed by an omentoplasty to fill the presacral cavity, preferably as a single-stage procedure.

Abstract
AIM Preoperative anaemia is associated with increased morbidity and mortality. The aim of this systematic review is to evaluate the efficacy of preoperative iron supplementation in the treatment of anaemia, and its effect on the postoperative recovery of patients undergoing surgery for colorectal carcinoma. METHOD This systematic review was performed using MEDLINE, EMBASE and the Cochrane library to assess current evidence on the role of iron supplementation in the treatment of preoperative anaemia. Our main outcomes were absolute increase in haemoglobin, blood transfusion rate and postoperative morbidity. Main inclusion criteria were: preoperative iron supplementation, presence of colorectal carcinoma and elective surgery. The Downs-Black questionnaire was used for quality assessment of the included studies. RESULTS Of the 605 studies analysed, seven, three randomized controlled trials and four cohort studies, were included. Despite iron supplementation, the three randomized controlled trials showed a decrease in haemoglobin level. This was contrary to the four cohort studies which all showed a significant increase. All studies showed a decreased blood transfusion rate following iron supplementation. None of the included studies assessed postoperative morbidity. Due to heterogeneity in study design, duration of treatment, dosages and variation in iron substrates, we were unable to perform a meta-analysis. CONCLUSION In anaemic patients who require surgery for colorectal carcinoma, current evidence is of inadequate quality to draw a definitive conclusion on the efficacy of the various measures to treat preoperative anaemia.

Abstract
BACKGROUND Case series suggest that laparoscopic peritoneal lavage might be a promising alternative to sigmoidectomy in patients with perforated diverticulitis. We aimed to assess the superiority of laparoscopic lavage compared with sigmoidectomy in patients with purulent perforated diverticulitis, with respect to overall long-term morbidity and mortality. METHODS We did a multicentre, parallel-group, randomised, open-label trial in 34 teaching hospitals and eight academic hospitals in Belgium, Italy, and the Netherlands (the Ladies trial). The Ladies trial is split into two groups: the LOLA group comparing laparoscopic lavage with sigmoidectomy and the DIVA group comparing Hartmann's procedure with sigmoidectomy plus primary anastomosis. The DIVA section of this trial is still underway but here we report the results of the LOLA section. Patients with purulent perforated diverticulitis were enrolled for LOLA, excluding patients with faecal peritonitis, aged older than 85 years, with high-dose steroid use (≥20 mg daily), and haemodynamic instability. Patients were randomly assigned (2:1:1; stratified by age [<60 years vs ≥60 years]) using secure online computer randomisation to laparoscopic lavage, Hartmann's procedure, or primary anastomosis in a parallel design after diagnostic laparoscopy. Patients were analysed according to a modified intention-to-treat principle and were followed up after the index operation at least once in the outpatient setting and after sigmoidoscopy and stoma reversal, according to local protocols. The primary endpoint was a composite endpoint of major morbidity and mortality within 12 months. This trial is registered with ClinicalTrials.gov, number NCT01317485. FINDINGS Between July 1, 2010, and Feb 22, 2013, 90 patients were randomly assigned in the LOLA section of the Ladies trial when the study was terminated by the data and safety monitoring board because of an increased event rate in the lavage group. Two patients were excluded for protocol violations. The primary endpoint occurred in 30 (67%) of 45 patients in the lavage group and 25 (60%) of 42 patients in the sigmoidectomy group (odds ratio 1·28, 95% CI 0·54-3·03, p=0·58). By 12 months, four patients had died after lavage and six patients had died after sigmoidectomy (p=0·43). INTERPRETATION Laparoscopic lavage is not superior to sigmoidectomy for the treatment of purulent perforated diverticulitis. FUNDING Netherlands Organisation for Health Research and Development.

We aimed to assess the superiority of laparoscopic lavage compared with sigmoidectomy in patients with purulent perforated diverticulitis, with respect to overall long-term morbidity and mortality. METHODS We did a multicentre, parallel-group, randomised, open-label trial in 34 teaching hospitals and eight academic hospitals in Belgium, Italy, and the Netherlands (the Ladies trial). The Ladies trial is split into two groups: the LOLA group comparing laparoscopic lavage with sigmoidectomy and the DIVA group comparing Hartmann's procedure with sigmoidectomy plus primary anastomosis. The DIVA section of this trial is still underway but here we report the results of the LOLA section. Patients with purulent perforated diverticulitis were enrolled for LOLA, excluding patients with faecal peritonitis, aged older than 85 years, with high-dose steroid use (≥20 mg daily), and haemodynamic instability. Patients were randomly assigned (2:1:1; stratified by age [<60 years vs ≥60 years]) using secure online computer randomisation to laparoscopic lavage, Hartmann's procedure, or primary anastomosis in a parallel design after diagnostic laparoscopy. Patients were analysed according to a modified intention-to-treat principle and were followed up after the index operation at least once in the outpatient setting and after sigmoidoscopy and stoma reversal, according to local protocols. The primary endpoint was a composite endpoint of major morbidity and mortality within 12 months. This trial is registered with ClinicalTrials.gov, number NCT01317485. FINDINGS Between July 1, 2010, and Feb 22, 2013, 90 patients were randomly assigned in the LOLA section of the Ladies trial when the study was terminated by the data and safety monitoring board because of an increased event rate in the lavage group. Two patients were excluded for protocol violations. The primary endpoint occurred in 30 (67%) of 45 patients in the lavage group and 25 (60%) of 42 patients in the sigmoidectomy group (odds ratio 1·28, 95% CI 0·54-3·03, p=0·58). By 12 months, four patients had died after lavage and six patients had died after sigmoidectomy (p=0·43). INTERPRETATION Laparoscopic lavage is not superior to sigmoidectomy for the treatment of purulent perforated diverticulitis. FUNDING Netherlands Organisation for Health Research and Development.

Adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with colon cancer at high risk of peritoneal carcinomatosis; the COLOPEC randomized multicentre trial. BMC Cancer 2015; 15:428. [PMID: 26003804 PMCID: PMC4492087 DOI: 10.1186/s12885-015-1430-7] [Citation(s) in RCA: 96] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2015] [Accepted: 05/13/2015] [Indexed: 12/17/2022] Open
Abstract
Background The peritoneum is the second most common site of recurrence in colorectal cancer. Early detection of peritoneal carcinomatosis (PC) by imaging is difficult. Patients eventually presenting with clinically apparent PC have a poor prognosis. Median survival is only about five months if untreated and the benefit of palliative systemic chemotherapy is limited. Only a quarter of patients are eligible for curative treatment, consisting of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CR/HIPEC). However, the effectiveness depends highly on the extent of disease and the treatment is associated with a considerable complication rate. These clinical problems underline the need for effective adjuvant therapy in high-risk patients to minimize the risk of outgrowth of peritoneal micro metastases. Adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) seems to be suitable for this purpose. Without the need for cytoreductive surgery, adjuvant HIPEC can be performed with a low complication rate and short hospital stay. Methods/Design The aim of this study is to determine the effectiveness of adjuvant HIPEC in preventing the development of PC in patients with colon cancer at high risk of peritoneal recurrence. This study will be performed in the nine Dutch HIPEC centres, starting in April 2015. Eligible for inclusion are patients who underwent curative resection for T4 or intra-abdominally perforated cM0 stage colon cancer. After resection of the primary tumour, 176 patients will be randomized to adjuvant HIPEC followed by routine adjuvant systemic chemotherapy in the experimental arm, or to systemic chemotherapy only in the control arm. Adjuvant HIPEC will be performed simultaneously or shortly after the primary resection. Oxaliplatin will be used as chemotherapeutic agent, for 30 min at 42-43 °C. Just before HIPEC, 5-fluorouracil and leucovorin will be administered intravenously. Primary endpoint is peritoneal disease-free survival at 18 months. Diagnostic laparoscopy will be performed routinely after 18 months postoperatively in both arms of the study in patients without evidence of disease based on routine follow-up using CT imaging and CEA. Discussion Adjuvant HIPEC is assumed to reduce the expected 25 % absolute risk of PC in patients with T4 or perforated colon cancer to a risk of 10 %. This reduction is likely to translate into a prolonged overall survival. Trial registration number NCT02231086 (Clinicaltrials.gov)

Early reconstruction of the leaking ileal pouch-anal anastomosis: a novel solution to an old problem. Colorectal Dis 2015; 17:426-32. [PMID: 25512241 DOI: 10.1111/codi.12867] [Citation(s) in RCA: 49] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2014] [Accepted: 10/08/2014] [Indexed: 02/08/2023]
Abstract
AIM The study aimed to determine the effectiveness and direct medical costs of early surgical closure of the anastomotic defect after a short course of Endo-sponge® therapy of the presacral cavity, compared with conventional treatment in patients with anastomotic leakage after ileal pouch-anal anastomosis (IPAA). METHOD Patients with anastomotic leakage after IPAA undergoing early surgical closure of the anastomotic defect after a short Endo-sponge® treatment were prospectively followed and compared with a consecutive cohort of patients with an anastomotic leak treated by creation of a loop ileostomy and occasional drainage of the presacral cavity. RESULTS A total of 15 patients were treated with early surgical closure and 29 were treated conventionally. In the early surgical closure group, the Endo-sponge® treatment was continued for a median of 12 days [interquartile range (IQR) 7-15 days] with a median of 3 (IQR 2-4) Endo-sponge® changes. Secondary anastomotic healing was achieved in all patients (n = 15) in the early surgical closure group compared with 52% (n = 16) in the conventional treatment group (P = 0.003). Closure of the anastomotic defect was achieved after a median of 48 (25-103) days in the early surgical closure group compared with 70 (IQR 49-175) days in the conventional treatment group (P = 0.013). A functional pouch was seen in 93% and 86% of the patients in each group. There was no significant difference in direct medical cost. CONCLUSION Early surgical closure after a short period of Endo-sponge® treatment is highly effective in treating anastomotic leakage after IPAA without increasing cost.

Perineal wound healing after abdominoperineal resection for rectal cancer: a two-centre experience in the era of intensified oncological treatment. Int J Colorectal Dis 2014; 29:1151-7. [PMID: 25064389 DOI: 10.1007/s00384-014-1967-y] [Citation(s) in RCA: 38] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 07/16/2014] [Indexed: 02/04/2023]
Abstract
PURPOSE Intensified treatment for distal rectal cancer has improved oncological outcome, but at the expense of more perineal wound complications in patients undergoing an abdominoperineal resection (APR). The aim of this study was to analyse perineal wound healing after APR with primary perineal wound closure over time. METHOD All patients undergoing APR for primary rectal cancer with primary wound closure between 2000 and 2013 were included and analysed in three consecutive time periods. Both early (<30 days postoperatively) and late perineal wound complications were determined. Independent risk factors of early perineal wound complications were identified using multivariable analysis. RESULTS A total of 136 patients were identified, of whom 129 patients underwent primary perineal wound closure. The use of neo-adjuvant (chemo)radiotherapy increased from 72 to 91%, and the use of an extralevator approach increased from 9 to 19%. The rate of early perineal wound complications increased from 18 to 31% and was independently associated with an extralevator approach [odds ratio (OR) 3.17; 95% confidence interval (CI) 1.16-8.66] and intra-operative perforation (OR 3.35; 95% CI 1.06-10.57). Perineal wound complications had no impact on local recurrence or 3-year overall survival rate. During a median follow-up of 28 months [interquartile range (IQR) 14-56], a persistent presacral sinus was diagnosed in 10%, and a perineal hernia occurred in 8% of the patients. CONCLUSION The increased use of an extralevator APR for rectal cancer significantly increased the risk of perineal wound complications over time. Intra-operative perforation was also independently associated with impaired perineal wound healing.

Randomized controlled multicentre study comparing biological mesh closure of the pelvic floor with primary perineal wound closure after extralevator abdominoperineal resection for rectal cancer (BIOPEX-study). BMC Surg 2014; 14:58. [PMID: 25163547 PMCID: PMC4158342 DOI: 10.1186/1471-2482-14-58] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2014] [Accepted: 08/21/2014] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Primary perineal wound closure after conventional abdominoperineal resection (cAPR) for rectal cancer has been the standard of care for many years. Since the introduction of neo-adjuvant radiotherapy and the extralevator APR (eAPR), oncological outcome has been improved, but at the cost of increased rates of perineal wound healing problems and perineal hernia. This has progressively increased the use of biological meshes, although not supported by sufficient evidence. The aim of this study is to determine the effectiveness of pelvic floor reconstruction using a biological mesh after standardized eAPR with neo-adjuvant (chemo)radiotherapy compared to primary perineal wound closure. METHODS/DESIGN In this multicentre randomized controlled trial, patients with a clinical diagnosis of primary rectal cancer who are scheduled for eAPR after neo-adjuvant (chemo)radiotherapy will be considered eligible. Exclusion criteria are prior radiotherapy, sacral resection above S4/S5, allergy to pig products or polysorbate, collagen disorders, and severe systemic diseases affecting wound healing, except for diabetes. After informed consent, 104 patients will be randomized between standard care using primary wound closure of the perineum and the experimental arm consisting of suturing a biological mesh derived from porcine dermis in the pelvic floor defect, followed by perineal closure similar to the control arm. Patients will be followed for one year after the intervention and outcome assessors and patients will be blinded for the study treatment. The primary endpoint is the percentage of uncomplicated perineal wound healing, defined as a Southampton wound score of less than II on day 30. Secondary endpoints are hospital stay, incidence of perineal hernia, quality of life, and costs. DISCUSSION The BIOPEX-study is the first randomized controlled multicentre study to determine the additive value of using a biological mesh for perineal wound closure after eAPR with neo-adjuvant radiotherapy compared to primary perineal wound closure with regard to perineal wound healing and the occurrence of perineal hernia. TRAIL REGISTRATION NUMBER NCT01927497 (Clinicaltrial.gov).

Tumour control by whole brain irradiation of anti-VEGF-treated mice bearing intracerebral glioma. Eur J Cancer 2009; 45:3074-80. [PMID: 19734041 DOI: 10.1016/j.ejca.2009.08.004] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2009] [Revised: 07/23/2009] [Accepted: 08/06/2009] [Indexed: 11/18/2022]
Abstract
AIM OF THE STUDY Tumour angiogenesis and invasion are key features of glioblastoma multiforme (GBM). Angiogenesis inhibitors increase progression-free survival (PFS) of recurrent GBM patients. VEGF inhibition controls the bulk tumour growth by inhibition of angiogenesis, but does not inhibit the invasive tumour component. We investigated if invasive tumour growth can be controlled by combining anti-VEGF treatment with irradiation of tumour plus surrounding brain in an orthotopic murine model for GBM. METHODS AND MATERIALS GBM cell line U251-NG2 was inoculated through a guide screw in the right frontal lobe of 53 athymic nude mice. Pegaptanib (a slow-releasing aptamer against VEGF) was injected in the tumour bed either or not followed by irradiation treatment with implanted I-125 seeds. Pegaptanib and/or irradiation were compared with sham-treated controls, resulting in four groups of 10-15 mice each. After 6 weeks of treatment, histological analysis was performed on all brains. RESULTS VEGF inhibition by locally deposited pegaptanib decreased tumour blood vessel density, and increased tumour hypoxia. Pegaptanib treatment still allowed the formation of tumour satellites. Irradiation decreased tumour size and suppressed formation of satellites. Combined pegaptanib plus irradiation further increased PFS. Tumour size directly correlated with PFS. CONCLUDING STATEMENT The anti-tumour effects of local VEGF inhibition are partially circumvented by the formation of invasive tumour satellites. Additional irradiation is effective in slowing down proliferation of these invasive tumour components.
