HAnd Suture Versus STApling for Closure of Loop Ileostomy (HASTA Trial): results of a multicenter randomized trial (DRKS00000040). Ann Surg. 2012;256:828-835; discussion 835-836. [PMID: 23095628 DOI: 10.1097/sla.0b013e318272df97]

Mechanically powered negative pressure dressing reduces surgical site infection after stoma reversal

Background

The use of closed-incision negative pressure wound therapy (ci-NPWT) has been shown to reduce postoperative wound complications and surgical site infections (SSI) after stoma closures. However, use of this approach has not been widely adopted due to high cost of the devices. We present a novel approach to stoma closure in which a self-contained mechanically powered negative pressure dressing (MP-NPD) is applied to primarily closed stoma reversal wounds. We hypothesized that SSI and wound complication rates would be improved compared to traditional stoma closure methods.

Methods

This was a prospective investigator-initiated study, in which consecutive patients that underwent stoma reversal with primary stoma wound closure dressed with MP-NPD from May 2021-March 2022. 30-day outcomes from the study group, including surgical site infection, other wound complications, hospital length of stay (LOS), and readmission rates, were then reported.

Results

Forty-six patients undergoing local ileostomy or colostomy closure were identified for the study group. Patient demographics and surgical variables were reported. One (2.2 %) patient in the study cohort developed superficial SSI within 30 days of their surgery. Post-op LOS in the study group versus was 4.1 days.

Conclusion

Intestinal stoma reversal wounds closed primarily and dressed with the MP-NPD dressings had very low stoma site SSI rates. These results are promising as they pertain to the use of MP-NPD in stoma reversal procedures, however further large prospective RCTs with a matched control group could help better corroborate these findings.

Current approach to loop ileostomy closure: a nationwide survey on behalf of the Italian Society of ColoRectal Surgery (SICCR)

Compared to standardized minimally invasive colorectal procedures, there is considerable perioperative heterogeneity in loop ileostomy reversal. This study aimed to investigate the current perioperative practice and technical variations of loop ileostomy reversal following rectal cancer surgery. A nationwide online survey was conducted among members of the Italian Society of ColoRectal Surgery (SICCR). A link to the questionnaire was sent via mail. The survey consisted of 31 questions concerning the main procedural steps and application of the ERAS protocol after loop ileostomy reversal. Overall, 219 participants completed the survey. One respondent in four used a combination of water-soluble contrast studies (WSCS) and digital rectal examination to assess the integrity of the anastomosis before ileostomy closure. Conversely, 17.8% of them used either only WSCS or only endoscopy. Surgeons routinely perform hand-sewn or stapled anastomoses in 45.2% and 54.8% of the cases, respectively. Side-to-side antiperistaltic stapled anastomosis was the most performed anastomosis (36%). Most surgeons declared that they have never used prostheses for abdominal wall closure (64%), whereas 35% preferred retromuscular mesh placement in selected cases only. Forty-six respondents (66.7%) reported using interrupted stitches for skin closure, while 65 (29.7%) a purse-string suture. Furthermore, skin approximation at the stoma site using open methods was significantly more common among surgeons with greater experience in ileostomy reversal (p = 0.031). Overall, a good compliance with the ERAS protocol was found. However, colorectal surgeons were significantly more likely to follow the ERAS pathway than general surgeons (p < 0.05). Surgeons use different anastomotic techniques for ileostomy reversal after rectal cancer surgery. Based on current evidence, purse-string skin closure and ERAS pathway should be implemented, while the role of mesh prophylactic strategy needs to be explored further.

Temporary diverting loop ileostomy in Crohn's disease surgery; indications and outcome

INTRODUCTION

Crohn's disease can present with complex surgical pathologies, posing a significant risk of morbidity and mortality for patients. The implementation of a loop ileostomy for selected patients may help minimize associated risks.

METHODS

In this retrospective cohort study, we investigated the utilization of temporary fecal diversion through the creation of a loop ileostomy in Crohn's surgery. Closure of all ostomies involved a hand-sewn single-layer technique. We then conducted bivariate analysis on 30-day outcomes for closures, focusing on favorable recovery defined as the restoration of bowel continuity without the occurrence of two challenges in recovery: newly developed organ dysfunction or the necessity for reoperation.

RESULTS

In total, 168 patients were included. The median age of the patients was 38 years (IQR 27-51). The most common indication for a loop ostomy was peritonitis (49%). After ileostomy closure, 163 patients (97%) achieved favorable recovery, while five encountered challenges; four (2.4%) underwent abdominal surgery, and one (0.6%) developed acute renal failure requiring dialysis. Two patients (1.2%) had a re-creation of ileostomy. Patients encountering challenges were older (56 [IQR 41-61] vs. 37 [IQR 27-50]; p 0.039) and more often required secondary intention wound healing (40% vs. 6.7%; p 0.049) and postoperative parenteral nutrition following their index surgery (83% vs. 26%; p 0.006).

CONCLUSION

Selectively staging the Crohn's disease operations with a loop ileostomy is a reliable practice with low morbidity and high restoration rates of bowel continuity. Our hand-sewn single-layer technique proves effective in achieving successful surgical recovery.

Loop Ileostomy Closure as a 23-Hour Stay Procedure With Preoperative Efferent Limb Enteral Stimulation: A Randomized Controlled Trial

BACKGROUND

Loop ileostomy closure is a common procedure in colorectal surgery. Often seen as a simple operation associated with a low complication rate, it still leads to lengthy hospitalizations. Reducing postoperative complications and ileus rates could lead to a shorter length of stay and even ambulatory surgery.

OBJECTIVES

This study aimed to assess the safety and feasibility of ileostomy closure performed in a 23-hour hospitalization setting using a standardized enhanced recovery pathway.

DESIGN

Randomized controlled trial.

SETTINGS

Two high-volume colorectal surgery centers.

PATIENTS

Healthy adults undergoing elective ileostomy closure from July 2019 to January 2022.

INTERVENTION

All patients were enrolled in a standardized enhanced recovery pathway specific to ileostomy closure, including daily irrigation of efferent limb with a nutritional formula for 7 days before surgery. Patients were randomly allocated to either conventional hospitalization (n = 23) or a 23-hour stay (n = 24).

MAIN OUTCOME MEASURES

Primary outcome was total length of stay and secondary outcomes were 30-day rates of readmission, postoperative ileus, surgical site infections, and postoperative morbidity and mortality.

RESULTS

A total of 47 patients were ultimately randomly allocated. Patients in the 23-hour hospitalization arm had a shorter median length of stay (1 vs 2 days, p = 0.02) and similar rates of readmission (4% vs 13%, p = 0.35), postoperative ileus (none in both arms), surgical site infection (0% vs 4%, p = 0.49), postoperative morbidity (21% vs 22%, p = 1.00), and mortality (none in both arms).

LIMITATIONS

Due to coronavirus disease 2019, access to surgical beds was greatly limited, leading to a shift toward ambulatory surgery for ileostomy closure. The study was terminated early, which affected its statistical power.

CONCLUSION

Loop ileostomy closures as 23-hour stay procedures are feasible and safe. Ileus rate might be reduced by preoperative intestinal stimulation with nutritional formula through the stoma's efferent limb, although specific randomized controlled trials are needed to confirm this association.

CIERRE DE ILEOSTOMA EN ASA COMO PROCEDIMIENTO AMBULATORIO DE HORAS CON ESTMULO PREOPERATORIO ENTERAL EFERENTE ESTUDIO ALEATORIO CONTROLADO

ANTECEDENTES:El cierre de la ileostomía en asa es un procedimiento común en la cirugía colorrectal. A menudo vista como una operación simple asociada con bajas tasas de complicaciones, aún conduce a largas hospitalizaciones. La reducción de las complicaciones postoperatorias y las tasas de íleo podría conducir a una estadía hospitalaria más corta o incluso a una cirugía ambulatoria.OBJETIVOS:El presente estudio pretende evaluar la seguridad y la viabilidad del cierre de ileostomía realizadas en un entorno de hospitalización de 23 horas utilizando una vía de recuperación mejorada y estandarizada.DISEÑO:Estudio aleatorio controladoAJUSTES:Dos centros de cirugía colorrectal de gran volúmenPACIENTES:Adultos sanos sometidos a cierre electivo de ileostomía, desde Julio de 2019 hasta Enero de 2022.INTERVENCIÓN:Todos los pacientes fueron inscritos en una vía de recuperación mejorada y estandarizada específica para el cierre de la ileostomía, incluyendo la irrigación diaria de la extremidad eferente del intestino asociada a una fórmula nutricional durante 7 días previos a la cirugía. Los pacientes fueron asignados aleatoriamente en hospitalización convencional (n = 23) o a una estadía de 23 horas (n = 24).PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue la duración total de la estadía hospitalaria y los resultados secundarios fueron las tasas de reingreso a los 30 días, el íleo postoperatorio, las infecciones de la herida quirúrgica, la morbilidad y mortalidad postoperatorias.RESULTADOS:Finalmente fueron randomizados un total de 47 pacientes. Aquellos que se encontraban en el grupo de hospitalización de 23 horas tuvieron una estadía media más corta (1 día versus 2 días, p = 0,02) y tasas similares de reingreso (4% vs 13%, p = 0,35), de íleo postoperatorio (ninguno en ambos brazos), de infección del sitio quirúrgico (0 vs 4%, p = 0,49), de morbilidad postoperatoria (21% vs 22%, p > 0,99) y de mortalidad (ninguna en ambos brazos).LIMITACIONES:Debido a la pandemia SARS CoV-2, el acceso a las camas quirúrgicas fue muy limitado, lo que llevó a un cambio hacia la cirugía ambulatoria para el cierre de ileostomías. El estudio finalizó anticipadamente, lo que afectó su poder estadístico.CONCLUSIÓN:Los cierres de ileostomía en asa como procedimientos de estadía de 23 horas son factibles y seguros. La tasa de íleo podría reducirse mediante la estimulación intestinal preoperatoria a través de la rama eferente del estoma asociada a fórmulas nutricionales, por lo que se necesitan estudios randomizados específicos para confirmar esta asociación.

Comparison of hand-sewn anterior repair, resection and hand-sewn anastomosis, resection and stapled anastomosis techniques for the reversal of diverting loop ileostomy after low anterior rectal resection: a randomized clinical trial

BACKGROUND

Low anterior resection in patients with rectal cancer may require a defunctioning loop ileostomy formation that requires closure after a period of time. There are three common techniques for ileostomy closure: anterior repair (AR or fold-over closure), resection and hand-sewn anastomosis (RHA), and resection and stapled anastomosis (RSA). We aimed to compare them on the basis of operative and postoperative features.

METHODS

Patients with rectal cancer who underwent low anterior resection without complications were included in this study and randomly assigned to three parallel groups to undergo loop ileostomy closure via either AR, RHA, or RSA. Early and late outcomes were gathered from all included patients.

RESULTS

Among 93 patients with a mean age of 56.21 ± 11.78 years, consisting of 58 (62.4%) men, 31 patients underwent AR, 30 patients RHA, and 32 patients RSA. There was no significant difference among the groups regarding the frequency and location of intraoperative injuries (P = 0.157). The AR groups demonstrated significantly less consumption of gauzes following intraoperative bleeding compared to the two others groups. The results showed that the duration of surgery in the RSA was significantly shorter than in the AR or RHA group (both P < 0.001). Regarding postoperative course, only one case of hematoma and two cases of surgical wound infection occurred in the RHA group. Anastomotic leakage and complete or partial obstruction did not occur in any group of patients. Latent postoperative complications did not occur in any group of patients. The median time between surgery and discharge as well as the interval until first gas passage, first defecation, oral tolerated liquid diet, as well as oral tolerated soft and regular diet in the AR group were significantly lower than in the two other groups (both P < 0.001). However, there was no statistical difference in these intervals between the RHA and RSA groups.

CONCLUSIONS

Resection and stapled anastomosis had the shortest duration among the three techniques; however, anterior repair had faster recovery, including earlier tolerated oral diet, gas passing and defecation, and discharge, in comparison with the other techniques.

Risk factors for surgical site infections and trends in skin closure technique after diverting loop ileostomy reversal: A multi-institutional analysis

BACKGROUND

Surgical site infections (SSIs) are one of the most common complications following diverting loop ileostomy (DLI) closures. This study assesses SSIs after DLI closure and the temporal trends in skin closure technique.

METHODS

A retrospective review was conducted using the American College of Surgeons National Surgical Quality Improvement Program database for adult patients who underwent a DLI closure between 2012 and 2021 across a multistate health system. Skin closure technique was categorized as primary, primary ​+ ​drain, or purse-string closure. The primary outcome was SSI at the former DLI site.

RESULTS

A SSI was diagnosed in 5.7% of patients; 6.9% for primary closure, 5.7% for primary closure ​+ ​drain, and 2.7% for purse-string closure (p ​= ​0.25). A diagnosis of Crohn's disease, diverticular disease, and increasing operative time were significant risk factors for SSIs. There was a positive trend in the use of purse-string closure over time (p ​< ​0.0001).

CONCLUSIONS

This study identified a low SSI rate after DLI closure which did not vary significantly based on skin closure technique. Utilization of purse-string closure increased over time.

Complications of preventive loop ileostomy versus colostomy: a meta-analysis, trial sequential analysis, and systematic review

BACKGROUND

Preventive colostomy is required for colorectal surgery, and the incidence of complications associated with ileostomy and colostomy remains controversial. This study aimed to compare the incidence of postoperative complications between ileostomy and colostomy procedures.

METHODS

Data analysis was conducted on 30 studies, and meta-analysis and trial sequential analysis (TSA) were performed on five studies. The basic indicators, such as stoma prolapse, leak, wound infection, ileus, and a series of other indicators, were compared.

RESULTS

No statistically significant differences were observed with complications other than stoma prolapse. Meta-analysis and TSA showed that the incidence of ileostomy prolapse was lower than that of colostomy prolapse, and the difference was statistically significant. Apart from the four complications listed above, the general data analysis showed differences in incidence between the two groups. The incidence of skin irritation, parastomal hernia, dehydration, pneumonia, and urinary tract infections was higher with ileostomy than with colostomy. In contrast, the incidence of parastomal fistula, stenosis, hemorrhage, and enterocutaneous fistula was higher with colostomy than with ileostomy.

CONCLUSIONS

There were differences in the incidence of ileostomy and colostomy complications in the selected studies, with a low incidence of ileostomy prolapse.

Stapled side-to-side anastomosis for ileostomy reversal: a simple and reproducible technique with video

INTRODUCTION

Protective diverting ileostomy is commonly performed in rectal surgery to avoid septic complications of low colorectal anastomosis. Ileostomy closure usually occurs three months after the surgery and can be realized in two ways: hand sewn or stapled. Existing randomized studies comparing the two techniques showed no difference in terms of complications.

METHODS

Our study describes the standard technique of ileostomy reversal as done in Bordeaux University Hospital in 10 steps individually illustrated and with an explicative video. We also collected data concerning the 50 last patients who underwent an ileostomy reversal in our center from June 2021 to June 2022.

RESULTS

Mean duration of the ileostomy closure was 46.8 minutes, and the mean total hospital stay was 4.66 days. Five of 50 (10%) patients had a post-operative bowel obstruction, 2/50 (4%) patients had a post-operative bleeding, 1/50 (2%) patient had a wound infection, and there was no anastomotic leakage observed.

CONCLUSION

Stapled side-to-side anastomosis is a rapid, simple, and reproducible technique for ileostomy reversal. There are no more complications compared to hand-sewn anastomosis. It engenders an additional cost compensated by the gain in operating time which altogether saves money.

Short-term outcome of diverting loop ileostomy reversals performed by residents: a retrospective cohort prognostic factor study

AIM

The reversal of diverting loop ileostomy (DLI) is one of surgical trainees' first procedures. Complications of DLI reversal can cause life-threatening complications and increase patient morbidity. This study compared DLI reversals performed by surgical trainees with those by attending surgeons.

METHOD

This retrospective cohort study was performed at a single primary care center on 300 patients undergoing DLI reversal. The primary outcome was morbidity, according to the Clavien-Dindo classification (CDC), with special attention paid to the surgeon's level of training. The secondary endpoint was postoperative intestinal motility dysfunction.

RESULTS

Surgical trainees had significantly longer operation times (p < 0.001) than attending surgeons. Univariate analyses revealed no influence on the level of training for postoperative morbidity. First bowel movement later than 3 days after surgery was a significant risk factor for CDC [Formula: see text] 3 (OR, 4.348; 96% CI, 1670-11.321; p = 0.003). Independent risk factors for surgical site infections (SSIs) were an elevated BMI (OR, 1.162; 95% CI, 1.043-1.1294; p = 0.007) and a delayed bowel movement (OR, 3.973; 95% CI, 1.300-12.138; p = 0.015). For postoperative intestinal motility dysfunction, an independent risk factor was a primary malignant disease (OR, 1.980; 95% CI, 1.120-3.500; p = 0.019), and side-to-side stapled anastomosis was a protective factor (OR, 0.337; 95% CI 0.155-0.733; p = 0.006).

CONCLUSION

Even though surgical trainees needed significantly more time to perform the surgery, the level of surgical training was not a risk factor for increased postoperative morbidity. Instead, delayed first bowel movement was predictive of SSI.

Hand-sewn direct repair versus resection and hand-sewn anastomosis techniques for the reversal of diverting loop ileostomy after lower anterior rectal resection surgery: A randomized clinical trial

INTRODUCTION

Several techniques have been proposed for the closure of loop ileostomy. This is the first study comparing bowel function and outcomes of two different hand-sewn surgical techniques used for the closure of diverting protective loop ileostomy.

METHOD

In this prospective, randomized, double-blind clinical trial, 40 patients with a history of rectal cancer, low anterior resection, and diverting loop ileostomy who were candidates for ileostomy reversal were included and randomly assigned into two groups, hand-sewn direct repair of the ileal defect (group A) and resection and hand-sewn anastomosis of the ileum (group B).

RESULTS

The mean age of patients was 56.42 and 52.10 years in groups A and B, respectively. Regarding early postoperative period, group A developed earlier first gas passage (1.68 vs. 2.25 days, p = 0.041) and stool passage (2.10 vs. 2.80 days, p = 0.032). Group A also revealed shorter operating time (83.68 vs. 89.50 min, p = 0.040) and hospital stay (4.73 vs. 6.80 days, p = 0.001). None of the participants in both groups developed signs of bowel obstruction during the early and late postoperative follow-up period.

CONCLUSIONS

Direct hand-sewn repair for the closure of diverting loop ileostomy is a safe technique with better postoperative bowel function, oral diet tolerance, and less hospital stay compared to resection and hand-sewn anastomosis of the ileum.

Rectal stimulation with prebiotics and probiotics before ileostomy reversal: a study protocol for a randomized controlled trial

BACKGROUND

Ileostomy closure is associated with a high rate of postoperative morbidity, and adynamic ileus is the most common complication, with an incidence of up to 32%. This complication is associated with delayed initiation of oral diet intake, abdominal distention, prolonged hospital stay, and more significant patient discomfort. The present study aims to evaluate the rectal stimulus with prebiotics and probiotics before ileostomy reversal.

METHODS

This is a protocol study for an open-label randomized controlled clinical trial. Ethical approval was received (CAAE: 56551722.6.0000.0071). The following criteria will be used for inclusion: adult patients with rectal cancer stages cT3/4Nx or cTxN+ that underwent loop protection ileostomy, patients treated with neoadjuvant chemoradiotherapy, and patients who underwent laparoscopic or robotic total mesorectal excision. Patients will be randomized to one of two groups. The intervention group (with rectal stimulus): the patients will apply 500 ml of saline solution with 6 g of Simbioflora® rectally, once a day, for 15 days before ileostomy closure. The control group (without rectal stimulation): the patients will close the ileostomy with no previous rectal stimulus. The primary outcomes will be the adynamic ileus (need for postoperative nasogastric tube insertion; nausea/vomiting; or intolerance to oral feedings within the first 72 h) and intestinal transit (time to first evacuation/flatus).

RESULTS

The patient's enrollment starts in January 2023. We expect to finish in July 2025.

DISCUSSION

The findings of this randomized clinical study may have important implications for managing patients undergoing ileostomy reversal.

TRIAL REGISTRATION

This study is registered in the Brazilian Trial Registry (ReBEC) under RBR-366n64w. Registration date: 19/07/2022.

Application and evaluation of transitory protective stoma in ovarian cancer surgery

Ovarian cancer is the most fatal of all female reproductive cancers. The fatality rate of OC is the highest among gynecological malignant tumors, and cytoreductive surgery is a common surgical procedure for patients with advanced ovarian cancer. To achieve satisfactory tumor reduction, intraoperative bowel surgery is often involved. Intestinal anastomosis is the traditional way to restore intestinal continuity, but the higher rate of postoperative complications still cannot be ignored. Transitory protective stoma can reduce the severity of postoperative complications and traumatic stress reaction and provide the opportunity for conservative treatment. But there are also many problems, such as stoma-related complications and the impact on social psychology. Therefore, it is essential to select appropriate patients according to the indications for the transitory protective stoma, and a customized postoperative care plan is needed specifically for the stoma population.

Feasibility and advantages analyses of wedge resection without mesentery detached approach applied to closure of loop ileostomy

OBJECTIVES

To evaluate the feasibility and advantages of wedge resection plus transverse suture without mesentery detached approach applied to loop ileostomy closure by analyzing the surgical data and the incidence of postoperative complications of patients undergoing this procedure.

METHODS

We performed a retrospective analysis of the hospitalization data of patients who underwent ileostomy closure surgery and met the research standards from January 2017 to April 2021 in Guangxi Medical University Cancer Hospital; all surgeries were performed by the same surgeon. The perioperative data were statistically analyzed by grouping.

RESULTS

In total, 65 patients were enrolled in this study, with 12 in the wedge resection group, 35 in the stapler group, and 18 in the hand suture group. There was no significant difference in operation time between the wedge resection group and stapler group (P > 0.05), but both groups had shorter operation time than that in the hand suture group (P < 0.05). The postoperative exhaustion time of wedge resection group was earlier than that of the others, and cost of surgical consumables in the wedge resection group was significantly lower than that in the stapler group, all with statistically significant differences (P < 0.05). By contrast, there were no statistically significant differences in postoperative complication incidences among the three groups.

CONCLUSIONS

The wedge resection plus transverse suture without mesentery detached approach is safe and easy for closure of loop ileostomy in selected patients, and the intestinal motility recovers rapidly postoperatively. It costs less surgical consumables, and is particularly suitable for the currently implemented Diagnosis-Related Groups payment method.

Hyperspectral imaging detects perfusion and oxygenation differences between stapled and hand-sewn intestinal anastomoses

OBJECTIVES

Hand-sewn and stapled intestinal anastomoses are both daily performed routine procedures by surgeons. Yet, differences in micro perfusion of these two surgical techniques and their impact on surgical outcomes are still insufficiently understood. Only recently, hyperspectral imaging (HSI) has been established as a non-invasive, contact-free, real-time assessment tool for tissue oxygenation and micro-perfusion. Hence, objective of this study was HSI assessment of different intestinal anastomotic techniques and analysis of patients' clinical outcome.

METHODS

Forty-six consecutive patients with an ileal-ileal anastomoses were included in our study; 21 side-to-side stapled and 25 end-to-end hand-sewn. Based on adsorption and reflectance of the analyzed tissue, chemical color imaging indicates oxygen saturation (StO2), tissue perfusion (near-infrared perfusion index [NIR]), organ hemoglobin index (OHI), and tissue water index (TWI).

RESULTS

StO2 as well as NIR of the region of interest (ROI) was significantly higher in stapled anastomoses as compared to hand-sewn ileal-ileal anastomoses (StO2 0.79 (0.74-0.81) vs. 0.66 (0.62-0.70); p<0.001 NIR 0.83 (0.70-0.86) vs. 0.70 (0.63-0.76); p=0.01). In both groups, neither anastomotic leakage nor abdominal septic complications nor patient death did occur.

CONCLUSIONS

Intraoperative HSI assessment is able to detect significant differences in tissue oxygenation and NIR of hand-sewn and stapled intestinal anastomoses. Long-term clinical consequences resulting from the reduced tissue oxygenation and tissue perfusion in hand-sewn anastomoses need to be evaluated in larger clinical trials, as patients may benefit from further refined surgical techniques.

Prognostic factors for complications after loop ileostomy reversal

BACKGROUND

Defunctioning ileostomy creation and closure are both associated with morbidity. There is little data available about complications after ileostomy closure. The aim of this study was to evaluate morbidity related to loop ileostomy closure (LIC) and to determine if patients with postoperative complications in primary surgery suffer from more postoperative complications during stoma closure.

METHODS

This was a retrospective study on prospectively registered consecutive patients undergoing elective LIC in a single centre in Spain between April 2010 and December 2017. Baseline characteristics, postoperative complications after primary surgery and after stoma closure were recorded. Primary surgery included any colorectal resection, elective or urgent associated with a diverting loop ileostomy either as a protective stoma or rescue procedure. A logistic regression model was used to assess the effects of baseline variables and postoperative complications after primary surgery on the existence of postoperative complications related to LIC.

RESULTS

Four hundred and twenty-eight patients (288 men, median age 64.5 years [IQR 55.1-72.3 years]) were included in the study, and 37.4%, developed complications after LIC. The most common was paralytic ileus. Only chronic kidney disease (OR 2.31; 95% CI 1.03-5.33, p = 0.043), existence of postoperative complications after primary surgery (OR 2.25; 95% CI 1.41-3.66, p =  < 0.001) and ileostomy closure later than 10 months after primary surgery (OR 1.52; 95% CI 1.00-2.33, p = 0.049) were statistically significant in the multivariate analysis.

CONCLUSIONS

Patients with chronic kidney disease, those who had any complication after primary surgery and those who had LIC > 10 months after primary surgery have a significantly higher risk of developing postoperative complications.

Surgical management of urinary diversion and stomas in adults: multidisciplinary Italian panel guidelines

BACKGROUND

Urinary stomas represent a worldwide medical and social problem. Data from literature about stoma management are extensive, but inhomogeneous. No guidelines exist about this topic. So, clear and comprehensive clinical guidelines based on evidence-based data and best practice are needed. This article aims to elaborate guidelines for practice management of urinary stomas in adults.

METHODS

Experts guided review of the literature was performed in PubMed, National Guideline Clearing-house and other databases (updated March 31, 2018). The research included guidelines, systematic reviews, meta-analysis, randomized clinical trials, cohort studies and case reports. Five main topics were identified: "stoma preparation", "stoma creation", "stoma complications", "stoma care" and "stoma reversal". The systematic review was performed for each topic and studies were evaluated according to the GRADE system, AGREE II tool. Recommendations were elaborated in the form of statements with an established grade of recommendation for each statement. For low level of scientific evidence statements a consensus conference composed by expert members of the major Italian scientific societies in the field of stoma management and care was performed.

RESULTS

After discussing, correcting, validating, or eliminating the statements by the experts, the final version of the guidelines with definitive recommendations was elaborated and prepared for publication. This manuscript is focused on statements about surgical management of urinary stomas. These guidelines include recommendations for adult patients only, articles published in English or Italian and with complete text available.

CONCLUSIONS

These guidelines represent the first Italian guidelines about urinary stoma multidisciplinary management with the aim to assist urologists and stoma specialized nurses during the urinary stoma management and care.

Increased risk of complications in smokers undergoing reversal of diverting ileostomy

BACKGROUND

Diverting ileostomy (DI) is utilised in rectal cancer surgery to mitigate the effects of anastomotic leak. The aim of this study was to assess the clinical risk factors associated with post-operative complications of DI reversal.

METHODS

A single-centre retrospective analysis of patients who underwent surgical resection for rectal cancer and subsequent DI reversal between January 2012 and December 2020 was undertaken. Medical records were reviewed to extract clinical, operative and pathologic details and post-operative complications according to the Clavien-Dindo classification. Univariate and multivariable analyses were undertaken to assess risk factors associated with post-operative complications of DI reversal.

RESULTS

One hundred and twenty-six adult patients who underwent DI reversal were included of which 49 had a post-operative complication (39%). The most common complication was prolonged post-operative ileus, which occurred in 24 patients (19%). On multivariable analysis smoking was significantly associated with overall complications (odds ratio [OR] = 5.60, 95% confidence interval [CI] 1.90-16.52, p = 0.0018), and high Clavien-Dindo (2-5) category complications (OR = 4.60, 95% CI 1.81-11.68, p = 0.0013). In addition, patients who received adjuvant chemotherapy were less likely to have a reversal of DI complication (OR = 0.43, 95% CI 0.19-0.94, p = 0.0342) and less likely to have a high Clavien-Dindo (2-5) category complication (OR = 0.44, 95% CI 0.20-0.93, p = 0.0311).

CONCLUSION

Smokers who have undergone surgical resection of rectal cancer have a significantly increased risk of post-operative complications after DI reversal. In these patients, the importance of smoking cessation must be emphasised. The decreased complication rate observed in patients who received adjuvant chemotherapy was an unexpected finding.

Risk factors for postoperative ileus following loop ileostomy closure

Objectives

The most common intra-abdominal complication following loop ileostomy closure (LIC) is postoperative ileus (POI). The aim of the study was to determine the risk factors of POI development following LIC and make recommendations for its prevention.

Material and Methods

In this study, patients having undergone LIC with peristomal incision following distal colorectal surgery were included. Clavien-Dindo classification was used to evaluate postoperative complications. POI and postoperative leakage were defined based on clinical and radiological criteria. The Centers for Disease Control and Prevention 2017 criteria were used to diagnose surgical site infection (SSI). Postoperative bleeding was diagnosed one day after surgery if there was a >2 g/dL or ≥15% decrease in the hemoglobin level.

Results

Seventy-nine patients were included into the study. In nine of the patients POI developed, six had SSI, five had postoperative bleeding, and two had anastomosis leakage. In the univariate analysis; age <60 years (p= 0.02), presence of comorbidity (p= 0.007), using an open technique in the first surgery (p= 0.02), performing total colectomy in the first surgery (p= 0.048), performing hand-sewn anastomosis of LIC (p= 0.01), and postoperative blood transfusion (p= 0.04) were found to be risk factors for POI. Performing hand-sewn anastomosis of LIC (p= 0.03) and using an open technique in the first surgery (p= 0.03) were found to be independent variables for POI risk.

Conclusion

Using an open technique in the first surgery and performing a hand-sewn anastomosis of LIC may increase POI.

Loop ileostomy closure: a retrospective comparison of three techniques

BACKGROUND

Loop ileostomy (LI) formation is a common practice for patients undergoing low anterior resection or restorative ileo-anal pouch surgery. Ileostomy closure can be performed using a stapled or hand-sewn technique, with or without resection. If hand-sewn, the closure can be one or two layers. Randomized controlled trials have not demonstrated one technique to be superior, and meta-analyses are limited by the heterogeneity of published studies. Our primary aim is to compare stapled ileostomy closure with single- and two-layer hand-sewn closures.

METHODS

This retrospective, single-centre cohort study included patients undergoing LI closure between January 1999 and April 2016. Patient demographics, anastomotic technique, operative time and patient outcomes were collected.

RESULTS

Our analysis included 244 patients (median age 67 years, 43.4% female). There were no significant differences in mean operative times (71.5, 73.1 and 88.5 min, for stapled, single- and two-layer hand-sewn closures, respectively, adjusted overall P = 0.262), or morbidity (21.5% versus 20.4% versus 17.6%, adjusted overall P = 0.934) between stapled or hand-sewn anastomoses, and no mortality. Once adjusting for age, sex, American College of Anaesthesiology grade, and consultant surgeon, the length of stay was different (overall P = 0.034), being similar between stapled and single-layer closures (4.2 versus 5.5 days, P = 0.105), but significantly different between stapled and two-layer closures (4.2 versus 8.3 days, P = 0.026).

CONCLUSION

Stapled and single-layered hand-sewn closures are similar in length of procedure, length of stay and complication rates. A two-layer, hand-sewn technique is associated with a significant increase in stay compared to a stapled ileostomy closure.

Chyme Reinfusion Is Associated with Lower Rate of Postoperative Ileus in Crohn's Disease Patients After Stoma Closure

BACKGROUND

The rate of postoperative ileus following stoma closure is high in patients with Crohn's disease and temporary enterostomy.

AIMS

To evaluate the effect of chyme reinfusion on postoperative outcomes including ileus in these patients.

METHODS

Patients were screened from January 2012 to December 2017 and divided into chyme reinfusion group (n = 33) and non-chyme reinfusion group (n = 84). The following 30-day postoperative outcomes were evaluated. Univariate and multivariate analyses and propensity score matching were performed to identify risk factors for these postoperative outcomes.

RESULTS

The incidence of postoperative ileus was significantly lower in the chyme reinfusion than in non-chyme reinfusion group, which had been confirmed by the results after matching (3/26 vs 11/26, p = 0.012). The rate of postoperative diarrhea was significantly lower in the chyme reinfusion group compared with non-chyme reinfusion group, whereas the difference was not significant after matching (2/26 vs 6/26, p = 0.191). Additionally, the postoperative length of stay was significantly shorter in the chyme reinfusion than in non-chyme reinfusion group before and after propensity score matching. In the multivariate analysis, chyme reinfusion was an independent protective factor for postoperative ileus (odds ratio 0.218; 95% confidence interval 0.05-0.95; p = 0.042) and for postoperative length of stay (coefficient - 0.191; 95% confidence interval - 0.350 to - 0.032, p = 0.019).

CONCLUSIONS

Chyme reinfusion was associated with lower rate of postoperative ileus and shorter length of stay following stoma closure in Crohn's patients with temporary ileostomy. Further randomized clinical trial between patients with or without chyme reinfusion was needed to confirm these conclusions.

Prediction model and web-based risk calculator for postoperative ileus after loop ileostomy closure

Background

Postoperative ileus (POI) is a significant complication after loop ileostomy closure given both its frequency and impact on the patient. The purpose of this study was to develop and externally validate a prediction model for POI after loop ileostomy closure.

Methods

The model was developed and validated according to the TRIPOD checklist for prediction model development and validation. The development cohort included consecutive patients who underwent loop ileostomy closure in two teaching hospitals in Montreal, Canada. Candidate variables considered for inclusion in the model were chosen a priori based on subject knowledge. The final prediction model, which modelled the 30-day cumulative incidence of POI using logistic regression, was selected using the highest area under the receiver operating characteristic curve (AUC) criterion. Model calibration was assessed using the Hosmer–Lemeshow goodness-of-fit test. The model was then validated externally in an independent cohort of similar patients from the University of British Columbia.

Results

The development cohort included 531 patients, in whom the incidence of POI was 16·8 per cent. The final model included five variables: age, ASA fitness grade, underlying pathology/treatment, interval between ileostomy creation and closure, and duration of surgery for ileostomy closure (AUC 0·68, 95 per cent c.i. 0·61 to 0·74). The model demonstrated good calibration (P = 0·142). The validation cohort consisted of 216 patients, and the incidence of POI was 15·7 per cent. On external validation, the model maintained good discrimination (AUC 0·72, 0·63 to 0·81) and calibration (P = 0·538).

Conclusion

A prediction model was developed for POI after loop ileostomy closure and included five variables. The model maintained good performance on external validation.

Incidence and predictors of postoperative ileus after loop ileostomy closure: a systematic review and meta-analysis

INTRODUCTION

Postoperative ileus (POI) is regarded as the most clinically significant morbidity following loop ileostomy closure; however, its incidence remains poorly understood. Our objective was therefore to determine the pooled incidence of POI after loop ileostomy closure and identify risk factors associated with its development.

METHODS

We systematically searched MEDLINE (via Ovid and PubMed), Embase, the Cochrane Library, Biosis Previews, and Scopus to identify studies reporting the incidence of POI in patients who underwent loop ileostomy closure. Two independent reviewers extracted data and appraised study quality. Cumulative incidence proportions were pooled across studies using a random-effects meta-analytic model.

RESULTS

Sixty-seven studies, including 9528 patients, met our inclusion criteria. The pooled estimate of POI was 8.0% (95% CI 6.9-9.3%; I² = 74%). The estimated incidence varied by POI definition: studies with a robust definition of POI (n = 8) demonstrated the highest estimate of POI (12.4%, 95% CI 9.2-16.5%; I² = 79%) while studies that did not report an explicit POI definition (n = 38) demonstrated the lowest estimate (6.7%, 95% CI 5.3-8.3%; I² = 61%). Small bowel anastomosis technique (hand-sewn) and interval time from ileostomy creation to closure (longer time) were the factors most commonly associated with POI after loop ileostomy closure. However, most comparative studies were not powered to examine risk factors for POI.

CONCLUSIONS

POI is an important complication after loop ileostomy closure, and its incidence is dependent on its definition. More research aimed at studying this complication is required to better understand risk factors for POI after loop ileostomy closure.

Stringent fluid management might help to prevent postoperative ileus after loop ileostomy closure

PURPOSE

The present study aimed to analyze the impact of perioperative fluid management on postoperative ileus (POI) after loop ileostomy closure.

METHODS

Consecutive loop ileostomy closures over a 6-year period (May 2011-May 2017) were included. Main outcomes were POI, defined as time to first stool beyond POD 3, and postoperative complications of any grade. Critical fluid management-related thresholds including postoperative weight gain were identified through receiver operator characteristics (ROC) analysis and tested in a multivariable analysis.

RESULTS

Of 238 included patients, 33 (14%) presented with POI; overall complications occurred in 91 patients (38%). 1.7 L IV fluids at postoperative day (POD) 0 was determined a critical threshold for POI (area under ROC curve (AUROC), 0.64), yielding a negative predictive value (NPV) of 93%. Further, a critical cutoff for a postoperative weight gain of 1.2 kg at POD 2 was identified (AUROC, 0.65; NPV, 95%). Multivariable analysis confirmed POD 0 fluids of > 1.7 L (OR, 4.7; 95% CI, 1.4-15.3; p = 0.01) and POD 2 weight gain of > 1.2 kg (OR, 3.1; 95% CI, 1-9.4; p = 0.046) as independent predictors for POI.

CONCLUSIONS

Perioperative fluid administration of > 1.7 L and POD 2 weight gain of > 1.2 kg represent critical thresholds for POI after loop ileostomy closure.

Reversal of Diverting Loop Ileostomy Using Hand-Sewn Side-to-Side versus End-to-End Anastomosis after Low Anterior Resection for Rectal Cancer: A Single Center Experience

Construction of diverting loop ileostomy has become a common adjunct to low anterior resection for rectal cancer because it substantially reduces the severity of postoperative morbidity. Various trials have compared hand-sewn with stapled anastomotic techniques, but the existing evidence regarding different configurations of hand-sewn anastomoses is scarce. The aim of this study is to compare the early postoperative outcomes of loop ileostomy reversal using the hand-sewn end-to-end or side-to-side configuration. A retrospective review was conducted on 62 consecutive patients undergoing ileostomy reversal between January 2012 and June 2017. The main outcome measure was postoperative bowel obstruction within 30 days after ileostomy reversal. Secondary outcomes included rate of anastomotic insufficiency, wound infection, reoperation, postoperative length of stay, and overall morbidity. The end-to-end (EE) anastomosis group consisted of 32 cases, whereas the side-to-side (SS) group consisted of 30 cases. Patient demographics, comorbidities, and BMI were similar between the two groups. No statistically significant difference was noted regarding postoperative bowel obstruction between the two groups [EE vs SS: 4/32 vs 0, P = 0.11]. Postoperative length of stay was longer for the EE group ( P = 0.03). Overall, 30-days morbidity was higher for the EE group (EE vs SS: 11/32 vs 3/30, P = 0.03). All other secondary outcomes did not differ between the two groups. No statistically significant difference was observed with regard to postoperative bowel obstruction. Overall, 30-days morbidity and postoperative length of stay were significantly higher for the EE group. Further randomized trials are required to verify our findings.

Comparison of Postradical Cystectomy Ileus Rates Using GIA-80 Versus GIA-60 Intestinal Stapler Device

OBJECTIVE

To assess the impact on recovery of bowel function using an 80 mm versus 60 mm gastrointestinal anastomosis (GIA) stapler following radical cystectomy and urinary diversion (RC/UD) for bladder cancer.

METHODS

We identified 696 patients using a prospectively maintained RC/UD database from January 2006 to November 2010. Two nonrandomized consecutive cohorts were compared. Patients between January 2006- and December 2007 (n = 180) were treated using a 60 mm GIA stapler, and 331 patients between January 2008 and December 2010 were subject to an 80 mm GIA stapler. All patients were treated on the same standardized postoperative recovery pathway. After accounting for baseline patient and perioperative characteristics, using a multivariable logistic regression model, we directly compared rates of postoperative ileus using a standardized definition.

RESULTS

Of 511 evaluable patients, ileus was observed in 32% (57/180) for 60 mm GIA versus 33% (110/331) for the 80 mm GIA. Preoperative renal function, age, gender, body mass index, and type of diversion were comparable between cohorts. On multivariate analysis, stapler size was not significantly associated with the development of ileus (GIA-60 vs GIA-80: OR 1.11; 95% CI 0.75, 1.66; P = .6). Positive fluid balance was associated with an increased risk (P = .019) and female sex a decreased risk (P = .008) of developing ileus compared to patients with negative fluid balance.

CONCLUSION

The size of the intestinal bowel anastomosis (GIA 80 mm vs 60 mm) does not independently impact the time to bowel recovery following RC/UD.

Morbidity associated with closure of ileostomy after a three-stage ileal pouch-anal anastomosis

The aim of the study was to compare the perioperative outcomes of patients undergoing ileostomy closure after a three-stage ileal pouch-anal anastomosis to a control group of patients who had elective colorectal resections and stoma, and to analyse the differences based on the technique of closure. The cases were retrospectively compared for demographic characteristics and postoperative outcomes. Chi-square, Fisher's exact and Wilcoxon rank sum tests were used as appropriate. Between 2011 and 2016, 338 patients having their stoma reversed after three-stage IPAA were compared to 158 patients in the control group. A younger age (43.2 vs 60.6 years, p < 0.0001), a lower body mass index (22 vs 24.4 kg/m², p < 0.0001), a higher rate of hand-sewn anastomosis (84.3 vs 15.7%, p < 0.0001), a lower rate of intraoperative complications (0 vs 1.2%, p = 0.038), a shorter operative time (91.5 vs 99.4 min, p = 0.0046) and length of hospital stay (6.6 vs 7.6 days, p = 0.045) were seen in the IPAA group. The 30-day rate of wound infection, anastomotic leak (0.6 vs 0.6%), small bowel obstruction (SBO, 8 vs 11.4%) and reoperation (1.8 vs 1.3%) was similar. Among IPAA patients, the hand-sewn anastomosis was correlated with a higher chance of developing SBO (9.1 vs 1.9%, p = 0.03). Closure of ileostomy after three-stage IPAA is associated with low rate of serious complications, despite the higher number of previous abdominal surgeries. This supports the construction of routine ileostomy during IPAA to reduce the risk of pelvic sepsis.

Outcome and Cost Analysis of Hand-Sewn and Stapled Anastomoses in the Reversal of Loop Ileostomy

Diverting loop ileostomies are common procedures for protecting high-risk anastomoses. There is little consensus on the most ideal technique both in terms of cost efficiency and outcome. Data for this study were collected from 101 patients who underwent loop ileostomy reversal between 2009 and 2014 at Morristown Medical Center. Of the 101 patients included in the review, 57 received a hand-sewn anastomosis (HS-A) and 44 received a stapled anastomosis (S-A). Average total hospital charges for stapled anastomoses were significantly greater than that for hand-sewn anastomoses, as were total operating room supply costs. When the total cost of the operation itself was considered, S-A cases were still found to be significantly greater than HS-A cases. Hospital room charges, total lab charges, pathology charges, and EKG/ECG charges were all greater for S-A cases than HS-A cases. Overall costs were greater for S-As than hand-sewn anastomoses and because of a lack of difference in procedure length, stapler supply costs were not offset. Complication rates and length of stay were also similar between the techniques. We found S-A cases to be more costly and have a greater cost/hour than HS-A cases.

Impact of surgical proficiency levels on postoperative morbidity: a single centre analysis of 558 ileostomy reversals

PURPOSE

Defunctioning ileostomies reduce the consequences of distal anastomotic leakage following bowel resections. Ileostomy reversal in itself, however, is associated with appreciable morbidity (3-40%) and mortality (0-4%). Despite being a common teaching procedure, there is limited information on the impact of surgical proficiency levels on postoperative outcome.

METHODS

Adult patients undergoing closure of a defunctioning ileostomy between September 2008 and January 2017 were identified from a surgical administrative database that was collected prospectively (n = 558). Baseline characteristics (age, ASA score, BMI, health care insurance coverage) and closure techniques were recorded. Operation time, rate of bowel resection, postoperative complications ranked by Clavien-Dindo classification and length of stay were analysed with respect to proficiency levels (residents vs. consultants).

RESULTS

Two hundred three ileostomy reversals were performed by residents; 355 ileostomies were closed by consultants. Operation time was considerably shorter in the consultant group (p < 0.001). Major postoperative complication rates however were not different among the groups when adjusted for possible confounders (p = 0.948). The rate of anastomotic leakage was 3% and the overall major morbidity rate was 11%.

CONCLUSION

Operation time rather than surgical outcome and overall morbidity were affected by surgical proficiency levels. Therefore, ileostomy reversal can be considered an appropriate teaching operation for young general surgery trainees.

Study protocol evaluating the use of bowel stimulation before loop ileostomy closure to reduce postoperative ileus: a multicenter randomized controlled trial

AIM

Postoperative ileus is the most commonly observed morbidity following ileostomy closure. Studies have demonstrated that the defunctionalized bowel of a loop ileostomy undergoes a series of functional and structural changes, such as atrophy of the intestinal villi and muscular layers, which may contribute to ileus. A single-centre study in Spain demonstrated that preoperative bowel stimulation via the distal limb of the loop ileostomy decreased postoperative ileus, length of stay and time to gastrointestinal function.

METHOD

A multicentre randomized controlled trial involving patients from Canadian institutions was designed to evaluate the effect of preoperative bowel stimulation before ileostomy closure on postoperative ileus. Stimulation will include canalizing the distal limb of the ileostomy loop with an 18Fr Foley catheter and infusing it with a solution of 500 ml of normal saline mixed with 30 g of a thickening agent (Nestle^© Thicken-Up^© ). This will be performed 10 times over the 3 weeks before ileostomy closure in an outpatient clinic setting by a trained Enterostomal Therapy nurse. Surgeons and the treating surgical team will be blinded to their patient's group allocation. Data regarding patient demographics, and operative and postoperative variables, will be collected prospectively. Primary outcome will be postoperative ileus, defined as an intolerance to oral food in the absence of clinical or radiological signs of obstruction, that either requires nasogastric tube insertion or is associated with two of the following on or after post-operative day 3: nausea/vomiting; abdominal distension; and the absence of flatus. Secondary outcomes will include length of stay, time to tolerating a regular diet, time to first passage of flatus or stool and overall morbidity. A cost analysis will be performed to compare the costs of conventional care with conventional care plus preoperative stimulation.

DISCUSSION

This manuscript discusses the potential benefits of preoperative bowel stimulation in improving postoperative outcomes and outlines our protocol for the first multicenter study to evaluate preoperative bowel stimulation before ileostomy closure. The results of this study could have considerable implications for the care of patients undergoing ileostomy closure.

Risk-adapted monitoring is not inferior to extensive on-site monitoring: Results of the ADAMON cluster-randomised study

Background

According to Good Clinical Practice, clinical trials must protect rights and safety of patients and make sure that the trial results are valid and interpretable. Monitoring on-site has an important role in achieving these objectives; it controls trial conduct at trial sites and informs the sponsor on systematic problems. In the past, extensive on-site monitoring with a particular focus on formal source data verification often lost sight of systematic problems in study procedures that endanger Good Clinical Practice objectives. ADAMON is a prospective, stratified, cluster-randomised, controlled study comparing extensive on-site monitoring with risk-adapted monitoring according to a previously published approach.

Methods

In all, 213 sites from 11 academic trials were cluster-randomised between extensive on-site monitoring (104) and risk-adapted monitoring (109). Independent post-trial audits using structured manuals were performed to determine the frequency of major Good Clinical Practice findings at the patient level. The primary outcome measure is the proportion of audited patients with at least one major audit finding. Analysis relies on logistic regression incorporating trial and monitoring arm as fixed effects and site as random effect. The hypothesis was that risk-adapted monitoring is non-inferior to extensive on-site monitoring with a non-inferiority margin of 0.60 (logit scale).

Results

Average number of monitoring visits and time spent on-site was 2.1 and 2.7 times higher in extensive on-site monitoring than in risk-adapted monitoring, respectively. A total of 156 (extensive on-site monitoring: 76; risk-adapted monitoring: 80) sites were audited. In 996 of 1618 audited patients, a total of 2456 major audit findings were documented. Depending on the trial, findings were identified in 18%–99% of the audited patients, with no marked monitoring effect in any of the trials. The estimated monitoring effect is −0.04 on the logit scale with two-sided 95% confidence interval (−0.40; 0.33), demonstrating that risk-adapted monitoring is non-inferior to extensive on-site monitoring. At most, extensive on-site monitoring could reduce the frequency of major Good Clinical Practice findings by 8.2% compared with risk-adapted monitoring.

Conclusion

Compared with risk-adapted monitoring, the potential benefit of extensive on-site monitoring is small relative to overall finding rates, although risk-adapted monitoring requires less than 50% of extensive on-site monitoring resources. Clusters of findings within trials suggest that complicated, overly specific or not properly justified protocol requirements contributed to the overall frequency of findings. Risk-adapted monitoring in only a sample of patients appears sufficient to identify systematic problems in the conduct of clinical trials. Risk-adapted monitoring has a part to play in quality control. However, no monitoring strategy can remedy defects in quality of design. Monitoring should be embedded in a comprehensive quality management approach covering the entire trial lifecycle.

Ileostomy reversal with handsewn techniques. Short-term outcomes in a teaching hospital

INTRODUCTION

Fecal diversion is considered an effective procedure to protect bowel anastomosis at high risk for leak. Some concerns exist regarding the risk for a significant morbidity associated to ileostomy creation itself and moreover to its closure. Surgical expertise and closure techniques are considered potential factors influencing morbidity. Aim of the study is to present a single-institution experience with ileostomy closures, in a teaching hospital, whereas ileostomy reversal is mainly performed by young residents.

METHODS

A prospective database was investigated to extract data of patients who underwent loop ileostomy closure between January 2005 and December 2014. Ileostomy reversion was always realized in a handsewn fashion, performing either a direct closure (DC) or a resection plus end-to-end anastomosis (EEA). Postoperative morbidity was graded according to Clavien-Dindo classification. Outcomes after DC and EEA were compared by Fisher's exact test and Wilcoxon rank-sum test.

RESULTS

Two hundred ninety-eight patients were included. Ileostomy reversal was performed by EEA in 236 patients (79.19 %) and by DC in 62 patients (20.81 %). Surgery was performed with a peristomal access in 296 cases (99.33 %). Incidence of anastomotic leak was 0.67 % (2/298). Overall reoperation rate was 0.34 % (1/298). Short-term overall morbidity rate was 20.47 %; but major complications (≥ grade III) occurred in only one patient (0.34 %). Mortality was nil. No significant differences in postoperative morbidity were found between the DC and EEA group.

CONCLUSION

Loop ileostomy reversal is a safe procedure, associated to a low major morbidity and excellent results, even if performed with a handsewn technique by supervised trainee surgeons.

Is "functional end-to-end anastomosis" really functional? A review of the literature on stapled anastomosis using linear staplers

PURPOSES

Anastomosis is one of the basic skills of a gastrointestinal surgeon. Stapling devices are widely used because stapled anastomosis (SA) can shorten operation times. Antiperistaltic stapled side-to-side anastomosis (SSSA) using linear staplers is a popular SA technique that is often referred to as "functional end-to-end anastomosis (FEEA)." The term "FEEA" has spread without any definite validation of its "function." The aim of this review is to show the heterogeneity of SA and conventional hand-sewn end-to-end anastomosis (HEEA) and to advocate the renaming of "FEEA."

METHODS

We conducted a narrative review of the literature on SSSA. We reviewed the literature on ileocolic and small intestinal anastomosis in colonic cancer, Crohn's disease and ileostomy closure due to the simplicity of the technique.

RESULTS

The superiority of SSSA in comparison to HEEA has been demonstrated in previous clinical studies concerning gastrointestinal anastomosis. Additionally, experimental studies have shown the differences between the two anastomotic techniques on peristalsis and the intestinal bacteria at the anastomotic site.

CONCLUSIONS

SSSA and HEEA affect the postoperative clinical outcome, electrophysiological peristalsis, and bacteriology in different manners; no current studies have shown the functional equality of SSSA and HEEA. However, the use of the terms "functional end-to-end anastomosis" and/or "FEEA" could cause confusion for surgeons and researchers and should therefore be avoided.

Preoperative oral polymeric diet enriched with transforming growth factor-beta 2 (Modulen) could decrease postoperative morbidity after surgery for complicated ileocolonic Crohn's disease

OBJECTIVE

Exclusive polymeric diet enriched with transforming growth factor-beta 2 (ANS-TGF-β2) has been used for remission induction and maintenance in pediatric Crohn's disease (CD). Its use in the preoperative setting has never been evaluated. The aim of this study was to evaluate preoperative ANS-TGF-β2 to decrease postoperative complications after surgery for complicated ileocolonic CD.

METHODS

From 2011 to 2015, data of all consecutive patients who underwent elective surgery for ileocolonic CD were collected prospectively. Preoperative, exclusive ANS-TGF-β2 was administered in high-risk patients with complicated CD. Complicated CD was defined by the presence of obstructive symptoms, and/or steroid treatment, and/or preoperative weight loss >10% and/or perforating CD. Outcomes of high-risk patients receiving preoperative ANS-TGF-β2 were compared to those of low-risk patients with no complicated CD who underwent upfront surgery.

RESULTS

Fifty-six patients underwent surgery for ileocolonic CD. Among them, 35 high-risk patients received preoperative ANS-TGF-β2 and 21 low-risk patients underwent upfront surgery. Preoperative full-dose ANS-TGF-β2 was feasible in 34/35 high-risk patients. Discontinuation of steroids during preoperative ANS-TGF-β2 could be achieved in 10/16 patients (62.5%). Postoperative complications rates were 8/35 (23.8%) and 5/21 (22.9%) in high-risk and low-risk patients, respectively (p = 1). Temporary ileocolostomy rates in high-risk patients and in low-risk patients were 4/35 (11%) and 0/21, respectively (p = 0.286) Conclusion: Preoperative ANS-TGF-β2 is feasible in most high-risk patients with complicated ileocolonic CD and could limit the deleterious effects of risk factors of postoperative morbidity. These results need to be confirmed in a large randomized controlled trial.

Temporary Diverting Ileostomy via the Umbilicus: a Small Case Series

The umbilicus, a natural orifice, which is used as an access port during laparoscopic surgery, can be used as a stoma site with potential superior cosmetic results as one less incision is then required. Our objective was to assess the efficacy and safety of the umbilical stoma in a selected group of patients. This is a prospective case series in hospital patients admitted as emergency or elective. Patients who underwent laparoscopic colorectal surgery with a planned ileostomy at Box Hill Hospital were approached and invited to participate in the study, with the stoma being fashioned on the umbilicus. Outcomes of interest included demographics, the details regarding the original indication for operation, operative and hospital related outcomes, postoperative bowel related complications, and other surgical and medical complications. Outcomes of a total of 10 (5 males) patients who underwent umbilical covering ileostomy during the study period were analyzed. Two patients with ulcerative colitis had the second stage of their operation converting their end stomas to loop stoma. These were counted twice, totaling 12 stomas in 10 patients. Three patients had their umbistomas after receiving neoadjuvant treatment for rectal cancer. The median period patients have had umbistomas is 113 days. Overall morbidity during the initial operation was low, except for 1 patient who had a small bowel injury. There was no mortality. Minor peristomal skin changes were the most common postoperative complication. Three patients had their stomas reversed with excellent cosmesis. Umbistomas appear to be a safe and effective way to fashion covering stomas post laparoscopic surgery and save the patient an added incision with excellent cosmetic results.

Incidence of neoplasias and effectiveness of postoperative surveillance endoscopy for patients with ulcerative colitis: comparison of ileorectal anastomosis and ileal pouch-anal anastomosis

BACKGROUND

The incidence of neoplasia after surgery has not been sufficiently evaluated in patients with ulcerative colitis (UC), particularly in the Japanese population, and it is not clear whether surveillance endoscopy is effective in detecting dysplasia/cancer in the remnant rectum or pouch. The aims of this study were to assess and compare postoperative development of dysplasia/cancer in patients with UC who underwent ileorectal anastomosis (IRA) or ileal pouch-anal anastomosis (IPAA) and to evaluate the effectiveness of postoperative surveillance endoscopy.

METHODS

One hundred twenty patients who received postoperative surveillance endoscopy were retrospectively reviewed for development of dysplasia/cancer in the remnant rectal mucosa or pouch.

RESULTS

Three hundred seventy-nine endoscopy sessions were conducted for 30 patients after IRA, while 548 pouch endoscopy sessions were conducted for 90 patients after IPAA. In the IRA group, 5 patients developed dysplasia/cancer during postoperative surveillance and in all cases, neoplasia was detected at an early stage. In the IRA group, no patient developed neoplasia within 10 years of diagnosis; the cumulative incidence of neoplasia after disease onset was 7.2, 12.0, and 23.9% at 15, 20, and 25 years, respectively. In one case after stapled IPAA, dysplasia was found at the ileal pouch; a subsequent 9 endoscopy sessions in 8 years did not detect any dysplasia. Neoplasia was found more frequently during postoperative surveillance in the IRA group than in the IPAA group (p = .0028). The cumulative incidence of neoplasia after IRA was 3.8, 8.7, and 21.7% at 10, 15, and 20 years, respectively, and that after IPAA was 1.6% at 20 years.

CONCLUSIONS

The cumulative incidence of neoplasia after IPAA was minimal. Those who underwent IRA had a greater risk of developing neoplasia than those who underwent IPAA, although postoperative surveillance endoscopy was able to detect dysplasia/cancer at an early stage. IRA can be the surgical procedure of choice only in selected cases in which it would be of benefit to the patient, with more careful surveillance.

Image-guided percutaneous drainage vs. surgical repair of gastrointestinal anastomotic leaks: is there a difference in hospital course or hospitalization cost?

PURPOSE

To identify differences in hospital course and hospitalization cost when comparing image-guided percutaneous drainage with surgical repair for gastrointestinal anastomotic leaks.

MATERIALS AND METHODS

A retrospective IRB-approved search using key words "leak" and/or "anastomotic" was performed on all adult CT reports from 2002 to 2011. CT examinations were reviewed for evidence of a postoperative gastrointestinal leak and assigned a confidence score of 1-5 (1 = no leak, 5 = definite leak). Patients with an average confidence score <4 were excluded. Type of surgery, patient data, method of leak management, number of hospital admissions, length of hospital stay, discharge disposition, number of CT examinations, number of drains, and hospitalization costs were collected.

RESULTS

One hundred thirty-nine patients had radiographic evidence of a gastrointestinal anastomotic leak (esophageal, gastric, small bowel or colonic). Nine patients were excluded due to low confidence scores. Twenty-seven patients underwent surgical repair (Group A) and 103 were managed entirely with percutaneous image-guided drainage (Group B). There was no significant difference in patient demographics or number of hospital admissions. Patients in Group A had longer median hospital stays compared to Group B (48 vs. 32 days, p = 0.007). The median total hospitalization cost for Group A was more than twice that for Group B ($99,995 vs. $47,838, p = 0.001). Differences in hospital disposition, number of CT examinations, number of drains, and time between original surgery and first CT examination were statistically significant.

CONCLUSION

Gastrointestinal anastomotic leaks managed by percutaneous drainage are associated with lower hospital cost and shorter hospital stays compared with surgical management.

Reversal of loop ileostomy under an Enhanced Recovery Programme - Is the stapled anastomosis technique still better than the handsewn technique?

INTRODUCTION

Recent literature suggests that stapled anastomotic (SA) technique for the reversal of loop ileostomy (LI) may be beneficial in terms of early recovery and reduced incidence of small bowel obstruction when compared to the handsewn anastomosis (HA). Enhanced Recovery Programme (ERP) after colorectal procedures has demonstrated a reduction in some aspects of surgical morbidity. The aim of this study was to investigate the outcomes of patients undergoing reversal of LI within an ERP programme and compare the HA to the SA in relation to clinical outcomes.

MATERIAL AND METHODS

All adult patients undergoing elective reversal of loop ileostomy between January 2008 and December 2012 without any additional procedures, were included in our study. Adherence to ERP modules and 30 day postoperative complications were assessed via retrospective review of patient case notes.

RESULTS

One hundred and eight patients had an ileostomy reversal; 61 in the SA and 47 in the HA group. There were no demographic differences between the two groups. ERP module compliance was satisfactory (>80%) in 11 of the 14 modules with no difference in individual module compliance between the two groups. The operating times were found to be comparable (p = 0.35). Overall mortality (p = 0.44), anastomotic leak rates (p = 1.00), intra-abdominal collections (p = 0.65), small bowel obstruction (p = 1.00), reoperation rates (p = 0.65), ileus (p = 0.14) and other significant complications (Clavien-Dindo > 2) (p = 0.08) were similar between the two groups. A significantly longer total length of hospital stay (TLOS) was found in the SA group (median 3 Vs 4 days, p = 0.009).

CONCLUSION

Reversal of LI under an ERP appears to potentially neutralise the suggested SA benefits in terms of postoperative complications without any additional negative implications. Other non-operative factors may have a potential effect on outcomes such as the TLOS.

[Patient-oriented multicentre research in surgery: the Surgical Trial Network (CHIR-Net)]

BACKGROUND

Patient-oriented clinical research in surgery requires prospective randomised multicentre trials (mRCTs) to generate valid evidence. In order to conduct high quality mRCTs, a network of surgical clinical trial centres is necessary.

METHODS

The Surgical Trial Network (CHIR-Net), which is funded by the German Federal Ministry of Education and Research (BMBF), was established as a structure of surgical regional centres. Currently, the CHIR-Net comprises 12 regional surgical centres with their associated clinical partner hospitals. The major aim of this network is to generate patient-relevant surgical questions of high clinical impact and to answer these questions in high-quality prospective randomised multicentre trials with well-trained study personnel.

RESULTS

Since 2006 32 mRCTs have been initiated in the CHIR-Net. Twelve surgical regional centres - in cooperation with 333 German and European hospitals - have recruited more than 7,500 patients. More than 80 surgeons have successfully completed the CHIR-Net educational curriculum for young surgeons.

CONCLUSIONS

The CHIR-Net has successfully established a national clinical trial network to investigate surgical questions in randomised multicentre clinical trials. A nationwide research infrastructure, including university and non-university hospitals as well as the associated clinical coordination centres (KKS), was created to ensure patient-oriented surgical clinical research in a network at the highest methodological level thus implementing evidence-based medicine in daily surgical practice.

Risk factors for postoperative ileus following radical resection for colorectal cancer

AIM: To investigate the risk factors for postoperative ileus following radical resection for colorectal cancer.

METHODS: A total of 1686 patients with colorectal cancer who underwent radical resection from January 2010 to January 2014 were enrolled for the prospective cohort study and received follow-up after discharge. Postoperative ileus was the outcome of follow-up. Patients with postoperative ileus were classified into group A (n = 90), and others into group B (n = 1596). Clinical data were compared between the two groups. Kaplan-Meier method was used to calculate the median time to postoperative ileus, and Cox proportional hazard model was performed to determine the risk factors.

RESULTS: The median follow-up time among the 1686 cases was 10.5 mo. Ninety cases developed postoperative ileus, and the median time to postoperative ileus was 2.46 wk. Stage Ⅲ disease, history of colorectal cancer resection, preoperative intestinal obstruction, hypoproteinemia, conversion to open surgery, right hemicolectomy, left hemicolectomy, operation time ≥ 3 h, and postoperative radiotherapy were independent risk factors of postoperative ileus following radical resection for elderly patients with colorectal cancer, and laparoscopic operation was an independent protective factor (P < 0.05).

CONCLUSION: Stage III disease, history of colorectal cancer resection, preoperative intestinal obstruction, hypoproteinemia, conversion to open surgery, right hemicolectomy, left hemicolectomy, operation time ≥ 3 h, and postoperative radiotherapy could increase the risk of postoperative ileus following radical resection for colorectal cancer, and laparoscopic operation could decrease the risk.

Hand suture versus stapler for closure of loop ileostomy--a systematic review and meta-analysis of randomized controlled trials

PURPOSE

The aims of this study are to compare the 30-day rate of bowel obstruction for stapled vs. handsewn closure of loop ileostomy, and to further assess efficacy and safety for each technique by secondary endpoints such as operative time, rates of anastomotic leakage, and other post-operative complications within 30 days.

METHODS

A systematic literature search (MEDLINE, The Cochrane Library, EMBASE and ISI Web of Science) was performed to identify randomized controlled trials (RCTs) comparing stapled and handsewn closure of loop ileostomy after low anterior resection. Random effects meta-analyses were calculated and presented as risk ratio (RR) and mean difference (MD) with corresponding 95 % confidence intervals.

RESULTS

Forty publications were retrieved and 4 RCTs (649 patients) were included. There was methodological and clinical heterogeneity of included trials, but statistical heterogeneity was low for most endpoints. Stapler use significantly reduced the rate of bowel obstruction compared to hand-sewn closure (RR 0.53 [0.32, 0.88]; P = 0.01). The operation time was significantly lower for stapling compared to hand suture (MD -15.5 min [-18.4, 12.6]; P < 0.001). All other secondary outcomes did not show significant differences.

CONCLUSIONS

This meta-analysis shows superiority of stapled closure of loop ileostomy compared to handsewn closure in terms of bowel obstruction rate and mean operation time. Other relevant complications such as anastomotic leakage are equivalent. Even so, both techniques are options with opposing advantages and disadvantages.

Morbidity of loop ileostomy closure after restorative proctocolectomy for ulcerative colitis and familial adenomatous polyposis: a systematic review

BACKGROUND

Temporary loop ileostomy is a routine procedure to reduce the morbidity of restorative proctocolectomy. However, morbidity of ileostomy closure could reduce the benefit of this concept. The objective of this systematic review was to assess the risks of ileostomy closure after restorative proctocolectomy for ulcerative colitis or familial adenomatous polyposis.

MATERIALS AND METHODS

Publications in English or German language reporting morbidity of ileostomy closure after restorative proctocolectomy were identified by Medline search. Two hundred thirty-two publications were screened, 143 were assessed in full-text, and finally 26 studies (reporting 2146 ileostomy closures) fulfilled the eligibility criteria. Weighted means for overall morbidity and mortality of ileostomy closure, rate of redo operations, anastomotic dehiscence, bowel obstruction, wound infection, and late complications were calculated.

RESULTS

Overall morbidity of ileostomy closure was 16.5 %, there was no mortality. Redo operations for complications were necessary in 3.0 %. Anastomotic dehiscence occurred in 2.0 %. Postoperative bowel obstruction developed in 7.6 %, with 2.9 % of patients requiring laparotomy for this complication. Wound infection rate was 4.0 %. Hernia or bowel obstruction as late complications developed in 1.9 and 9.4 %, respectively.

CONCLUSION

The considerable morbidity of ileostomy reversal reduces the overall benefit of temporary fecal diversion. However, ileostomy creation is still recommended, as it effectively reduces the risk of pouch-related septic complications.

Stimulation of the efferent limb before ileostomy closure: a randomized clinical trial

BACKGROUND

Postoperative ileus is the most common complication after ileostomy closure with an increase in morbidity, hospital stay, and health care costs.

OBJECTIVE

The aim of this study is to assess the utility of a new technique for reducing postoperative ileus after protective ileostomy closure.

DESIGN

This is a prospective randomized study registered at ClinicalTrials.gov (NCT01881594). Patients were randomly assigned to undergo either stimulation through the efferent limb of the ileostomy before surgery or nonstimulation before surgery.

SETTING

This study was conducted at the Department of Surgery of the Virgen de la Arrixaca Clinical University Hospital (Murcia).

PATIENTS

Seventy patients underwent surgery for ileostomy closure. In 35 patients, during the 2 weeks before surgery, daily stimulation of the defunctionalized stomal segment was performed by using a thick solution (500 mL of physiological saline associated with 30 g of thickening agent, Nestle Resource, Vevey, Switzerland). In the other 35 patients, stimulation was not performed before surgery.

MAIN OUTCOME MEASURES

The primary outcome was postoperative ileus. The secondary outcomes included time to tolerating a diet and postoperative stay.

RESULTS

Both groups of patients were homogenous for demographic data, characteristics of the first rectal cancer operation, and intersurgery periods. After ileostomy closure, the stimulated group of patients had an earlier return to oral tolerance (1.06 vs 2.57 days; p = 0.007) and passage of flatus or stool (1.14 vs 2.85 days; p <0.001) than the nonstimulated group of patients. The incidence of postoperative ileus (2.85% vs 20%; p = 0.024) and hospital stay (2.49 vs 4.61 days; p = 0.002) was also lower in the stimulated patients.

LIMITATIONS

Small numbers of patients means that no definitive statements can be made regarding the effectiveness of this technique.

CONCLUSIONS

Stimulation of the efferent limb of the ileostomy before closure is a safe technique that reduces postoperative ileus and fosters early intestinal transit and oral tolerance with a shorter postoperative hospital stay.
