Abstract
BACKGROUND Restorative proctocolectomy and IPAA have become the surgical procedure of choice in pediatric patients with medically refractory colitis or familial adenomatous polyposis. OBJECTIVE This systematic review aims to assess the diagnosis and treatment of pouch disorders in pediatric patients who undergo IPAA. DATA SOURCES A literature search was performed using MEDLINE, Google Scholar, and Embase for all publications describing outcomes of pediatric IPAA. STUDY SELECTION Studies between January 1, 2000, and September 7, 2022, published in English were included. Studies were excluded on the basis of title, abstract, and full-length review. INTERVENTIONS IPAA. MAIN OUTCOME MEASURES Pouch disorders described include anastomotic leaks, pouch strictures, pouch failure, pouchitis, cuffitis, and de novo Crohn's disease of the pouch. RESULTS Thirty-three studies were included in this review, all of which were retrospective in nature. The outcomes of 2643 pediatric patients were included in the 33 studies. LIMITATIONS Management is largely informed by clinical practices in adult patients with scant data on treatment efficacy in children. CONCLUSIONS The reported incidence of disorders of the pouch in children varies widely and is likely attributable to differences in definitions and follow-up periods across studies. Pouchitis was the most frequently described outcome. The overall rate of pouch failure in children is relatively low, with de novo Crohn's disease of the pouch being the most significant risk factor. Multicenter prospective studies are needed in the pediatric population to accurately identify risk factors, standardize the assessment of pouch complications, and determine effective treatment strategies.

Anastomotic leaks and the relationship with anastomotic strictures after esophageal atresia surgery; effects of patient characteristics. Acta Chir Belg 2024; 124:114-120. [PMID: 37243696 DOI: 10.1080/00015458.2023.2219521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Accepted: 05/25/2023] [Indexed: 06/02/2023]
Abstract
BACKGROUND This study aimed to evaluate the link between anastomotic leaks (AL) and anastomotic strictures (AS) after esophageal atresia surgery and the influence of patient demographics. MATERIALS AND METHODS The clinical data of neonates who underwent surgical repair for esophageal atresia were retrospectively reviewed. The results of AL treatment and the relationship with AS, also the effects of patient characteristics were examined with logistic regression analysis. RESULTS Primary repair was performed on 122 of 125 patients who underwent surgery for esophageal atresia. AL occurred in 25 patients and 21 were treated non-operatively. While 4 patients were re-operated, AL recurred in 3 and led to the death of one. There was no correlation between the development of AL and sex or the presence of additional anomalies. The gestational age and birth weight of patients with AL were significantly higher than those of patients without. AS developed in 45 patients. The mean gestational age was significantly higher in patients who developed AS (p < .001). While the development of AS was significantly higher in patients with AL (p = .001), the number of dilatation sessions needed was also significantly higher in these patients (p = .026). Complications related to anastomosis were less common in patients whose gestational age was ≤33 weeks. CONCLUSION Non-operative treatment remains effective for AL after esophageal atresia surgery. AL increases the risk of developing AS and significantly increases the number of dilatation sessions needed. Anastomotic complications are less common in patients with lower gestational age.NOVEL ASPECTSGestational age and birth weight were found to be significantly higher in patients with anastomotic leaks than in those without and fewer anastomotic complications were encountered in patients whose gestational age was ≤ 33 weeks.Anastomotic stricture development was significantly higher in patients with anastomotic leaks and the number of dilatation sessions needed for treatment was also significantly higher in these patients.

Replogle Modified Endoscopic Vacuum-Assisted Closure (EVAC) Therapy: A New Strategy to Treat Anastomotic Leakage and Esophageal Perforation. J Pediatr Surg 2024; 59:432-436. [PMID: 37949689 DOI: 10.1016/j.jpedsurg.2023.09.043] [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: 07/23/2023] [Revised: 09/29/2023] [Accepted: 09/30/2023] [Indexed: 11/12/2023]
Abstract
BACKGROUND Anastomotic leakage (AL) and esophageal perforation are life-threatening complications following surgery or endoscopic dilations. "Replogle modified EVAC therapy" consists of placing a Replogle tube directly into the lumen or within an abscess cavity and remove by suction all intra-cavity fluids and secretion with a continuous low-pressure suction, promoting granulation tissue proliferation, thereby gradually decreasing the cavity size. The aim of our study was to evaluate the technical feasibility, safety, and efficacy of this technique in pediatric patients. METHODS A retrospective review charts of consecutive pediatric patients that were treated with "Replogle modified EVAC therapy" at our pediatric referral center between 2013 and 2022 was conducted. The clinical, endoscopic, radiological, and surgical information and data of patients were collected and revised as well as their follow-up and outcomes. RESULTS Ten patients (6/10 male; mean age: 7.8 y.o., range: 1.1-18 y.o.) were treated using the "Replogle modified EVAC therapy". Four out of ten patients developed esophageal perforations after endoscopic procedures. Six out of the ten enrolled patients had AL complications after surgical operations. All patients were successfully treated. There were no technical failures or complications with device placement. Mean treatment duration was 16 days (range 7-41 days). No additional treatment was needed for complete leak resolution. CONCLUSIONS "Replogle modified EVAC therapy" represents a promising and mini-invasive method to treat esophageal perforations and post-surgical leak in the paediatric age group. In our experience, the use of this technique was safe, effective, and particularly well suited also in complex paediatric patients. LEVEL OF EVIDENCE IV.

Anastomotic Leakage after Gastrectomy for Gastric Cancer. JOURNAL OF GASTROINTESTINAL AND LIVER DISEASES : JGLD 2023; 32:526-535. [PMID: 38147605 DOI: 10.15403/jgld-5238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2023] [Accepted: 10/15/2023] [Indexed: 12/28/2023]
Abstract
Anastomotic leakage (AL) constitutes a prominent cause of significant morbidity following gastrectomy for gastric cancer. The manifestation of AL typically occurs within 7 to 10 days post-surgery, with reported incidence rates of 5.8-6.7% for open gastrectomy and 3.3-4.1% for laparoscopic gastrectomy. Various predisposing risk factors have been identified, including the individual nutritional status (excluding obesity) and preoperative corticotherapy. Interestingly, the administration of neoadjuvant therapies appears to reduce the AL occurrence. In the context of distal gastrectomies, the rates of AL are comparable between laparoscopic, robotic, and open approaches. The total gastrectomies have higher AL rate compared to distal gastrectomies, which are considered the preferred approach. Prophylactic drainage measures have not demonstrated efficacy in preventing AL. As for postoperative management, conservative treatment is indicated for patients presenting with mild clinical symptoms and increased inflammatory blood tests. This approach involves fasting, enteral or parenteral nutrition, administration of antibiotics, and percutaneous drainage. For small AL, endoscopic therapies such as stents, vacuum therapy, clips, suturing devices, and injections are appropriate treatment options. In cases of high-volume fistulas, severe sepsis or failure of previous therapies, surgical reoperation becomes the ultimate solution.

Effect of noninvasive respiratory support after extubation on postoperative pulmonary complications in obese patients: A systematic review and network meta-analysis. J Clin Anesth 2023; 91:111280. [PMID: 37801822 DOI: 10.1016/j.jclinane.2023.111280] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Revised: 09/16/2023] [Accepted: 09/27/2023] [Indexed: 10/08/2023]
Abstract
STUDY OBJECTIVE Obesity is associated with an increased risk of sleep-disordered breathing (SDB) and postoperative pulmonary complications (PPCs). Postoperative noninvasive respiratory support (NRS) has been recommended to obese patients despite the controversy about its benefit. The network meta-analysis (NMA) was used in this study to compare the effect of different methods of NRS on preventing PPCs in obese patients. DESIGN This study is a network meta-analysis. SETTING Post-anesthesia care unit and inpatient ward. PATIENTS 20 randomized controlled trials involving 1184 obese patients were included in the final analysis. INTERVENTIONS One of the four NRS techniques, which include continuous positive airway pressure (CPAP), bi-level positive airway pressure (BiPAP), high-flow nasal cannula (HFNC), or conventional oxygen therapy (COT), was performed after general anesthesia. MEASUREMENTS The primary outcome was the incidence of PPCs, e.g., atelectasis, pneumonia, hypoxemia, and respiratory failure. The secondary outcomes included the incidence of oxygen treatment failure and anastomotic leakage, oxygenation index, and length of hospital stay (LOS). RevMan 5.3 and STATA 16.0 were used to analyze the results and any potential bias. MAIN RESULTS Compared with COT, BiPAP and HFNC were both effective in reducing the occurrence of postoperative atelectasis. There were no significant differences in the occurrence of other PPCs including pneumonia, hypoxemia and respiratory failure between the four NRS techniques. CPAP and HFNC were superior to other techniques in improving oxygenation and shortening LOS respectively. No differences were found in oxygen treatment failure and anastomotic leakage between the patients with different NRS. HFNC ranked the first in five of the eight outcomes (hypoxemia, respiratory failure, treatment failure, anastomotic leakage, LOS) in this review by the surface under the cumulative ranking curve (SUCRA). CONCLUSION Among the four postoperative NRS techniques, HFNC seems to be the optimal choice for obese patients which shows certain advantages in reducing the risk of PPCs and shortening LOS.

Diagnosis and management of anastomotic leaks after Ivor Lewis esophagectomy: a single-center experience. Langenbecks Arch Surg 2023; 408:397. [PMID: 37831200 DOI: 10.1007/s00423-023-03121-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Accepted: 09/25/2023] [Indexed: 10/14/2023]
Abstract
PURPOSE Esophageal anastomotic leaks (ALs) after esophagectomy are a common and serious complication. The incidence, diagnostic approach, and management have changed over time. We described the diagnosis and management of patients who developed an esophageal AL after an Ivor Lewis esophagectomy at our center. METHODS After IRB approval, we queried our prospectively maintained database for patients who developed an esophageal AL after esophagectomy from August 2016 through July 2022. Data pertaining to demographics, comorbidities, surgical and oncological characteristics, and clinical course were extracted and analyzed. RESULTS During the study period, 145 patients underwent an Ivor Lewis esophagectomy; 10 (6.9%) developed an AL, diagnosed a median of 7.5 days after surgery, and detected by enteric contents in wound drains (n = 3), endoscopy (n = 3), CT (n = 2), and contrast esophagogram (n = 2). Nine patients (90%) had an increasing white blood cell count and additional signs of sepsis. One asymptomatic patient was identified by contrast esophagography. All patients received enteral nutritional support, intravenous antibiotics, and antifungals. Primary treatment of ALs included endoscopic placement of a self-expanding metal stent (SEMS; n = 6), surgery (n = 2), and SEMS with endoluminal vacuum therapy (n = 2). One patient required surgery after SEMS placement. The median length of ICU and total hospital stays were 11.5 and 22.5 days, respectively. There was no 30-day mortality. CONCLUSION The incidence of esophageal ALs at our center is similar to that of other high-volume centers. Most ALs can be managed without surgery; however, ALs remain a significant source of postoperative morbidity despite clinical advancements that have improved mortality.

Abstract
BACKGROUND : Endoscopic vacuum therapy (EVT) is a novel treatment for esophageal perforations. This study aimed to describe initial experience with EVT of esophageal perforations due to iatrogenic cause, Boerhaave syndrome, or other perforations not related to prior upper gastrointestinal surgery. METHODS : Data from patients treated with EVT for esophageal perforation at five hospitals in three European countries, between January 2018 and October 2021, were retrospectively collected. The primary end point was successful defect closure by EVT, with or without the use of other endoscopic treatment modalities. Secondary end points included mortality and adverse events. RESULTS : 27 patients were included (median age 71 years). The success rate was 89 % (24/27, 95 %CI 77-100). EVT failed in three patients: two deceased during EVT (septic embolic stroke, pulmonary embolism) and one underwent esophagectomy due to a persisting defect. Two adverse events occurred: one iatrogenic defect expansion during sponge exchange and one hemorrhage during sponge removal. Median treatment duration was 12 days (interquartile range [IQR] 6-16) with 1 sponge exchange (IQR 1-3). CONCLUSION : EVT is a promising organ-preserving treatment for esophageal perforations, with a success rate of 89 %. More experience with the technique and indications will likely improve success rates.

Challenges in the interdisciplinary treatment of leakages after left-sided colorectal surgery: endoscopic negative pressure therapy, open-pore film drainage therapy and beyond. Int J Colorectal Dis 2023; 38:138.

Abstract
PURPOSE The treatment of anastomotic leakage after left colorectal surgery remains challenging. Since its introduction, endoscopic negative pressure therapy (ENPT) has proven to be advantageous, reducing the necessity of surgical revision. The aim of our study is to present our experience with endoscopic treatment of colorectal leakages and to identify potential factors influencing treatment outcome. METHODS Patients who underwent endoscopic treatment of colorectal leakage were retrospectively analyzed. Primary endpoint was the healing rate and success of endoscopic therapy. RESULTS We identified 59 patients treated with ENPT between January 2009 and December 2019. The overall closure rate was 83%, whereas only 60% of the patients were successfully treated with ENPT and 23% needed further surgery. The time between diagnosis of leakage and uptake of endoscopic treatment did not influence the closure rate, but patients with chronic fistula (> 4 weeks) showed a significantly higher reoperation rate than those with an acute fistula (94% vs 6%, p = 0.01). CONCLUSION ENPT is a successful treatment option for colorectal leakages, which appears to be more favorable when started early. Further studies are still needed to better describe its healing potential, but it deserves an integral role in the interdisciplinary treatment of anastomotic leakages.

Abstract
Gastrointestinal postoperative anastomotic leaks and fistulas occur frequently and many are managed surgically; however, endoscopic interventions have shown to improve healing outcomes and length of hospital stay. The experience of vacuum-assisted closure therapy (E-VAC) is described, in complications such as fistulas and postoperative anastomotic leaks, in a gastrointestinal reference center in Colombia. A case series study was carried out in patients with anastomotic leaks and fistulas at different levels of the digestive tract, treated by E-VAC, by the Gastroenterology Service in Colombia, during a period from February 2019 to November 2021. Sociodemographic, clinical and surgical variables were described. 6 cases are described, 4 from lower digestive tract and 2 from upper digestive tract. 83% were men; the mean age was 51.8 years (+/-17.5). The indication for E-VAC was colorectal anastomotic fistula in 66%; the most frequent anatomical location was near the anal region (66%), less frequently at the level of the cardia (16%) and esophagus (16%). The size of the defect was described between 20 and 80% in patients undergoing E-VAC therapy, with an average hospitalization length of stay of 22.5 days, with an average number of exchanges of seven per patient. Anastomotic leaks and fistulas are potentially fatal complications in gastrointestinal surgery. E-VAC therapy has shown to be effective and safe, promoting defect closure and drainage of collections present, also decreasing the length of hospital stay.

Abstract
Jejunostomy tubes are frequently placed at time of esophagectomy. The purpose of this study is to evaluate cessation of routine j-tube placement on postoperative body mass index (BMI), return to the emergency room, and time until adjuvant therapy. We performed a retrospective review of an institutional database for consecutive patients undergoing minimally invasive Ivor Lewis Esophagectomy from 2014-2021 (after January 2019, routine j-tube placement was abandoned). Data was analyzed using Pearson's Chi-squared tests and Student's t test with 2-sided significance level of P < 0.05. In total,179 patients were included, 95 underwent j-tube placement and 84 did not. Cohorts had comparable baseline BMI's (no j-tube: 30.48 vs j-tube: 28.64, P = 0.06) and anastomotic leak rates (2.4% vs 4.2%, P = 0.5). Patients with no jejunostomy tubes were more likely to receive total parenteral nutrition (14.3% vs 5.3%, P < 0.05), but were no more likely to require total parenteral nutrition at discharge and had comparable durations of TPN requirement (7 days vs 12 days, P = 0.53). There was no difference in mean BMI reduction at 2 weeks (2.54 vs 2.09, P = 0.49) and 3-6 months postoperatively (6.11 vs 4.45 P = 0.15). There was no difference in return to the emergency room (8.3% vs 8.4%, P = 0.98) or readmissions (13.1% vs 11.6%, P = 0.76). There was a no difference in mean time to adjuvant therapy (83.5 days vs 72.6 days, P = 0.67). At esophagectomy centers with low anastomotic leak rates, cessation of routine j-tube placement at time of minimally esophagectomy can be undertaken without increasing risk of readmission, time until initiation of adjuvant therapy, or significantly impacting postoperative BMI loss.

Abstract
BACKGROUND Endoscopic vacuum therapy for the treatment of rectal anastomotic leak has been shown to be effective and safe. The majority of patients are treated after fecal diversion to avoid further septic complications. OBJECTIVE To report the effectiveness of endoscopic vacuum therapy for rectal anastomotic leak without diversion compared to secondary stoma creation. DESIGN Retrospective cohort analysis. SETTINGS University hospital, single-center. PATIENTS Patients undergoing sigmoid or rectal resection without fecal diversion during primary surgery who were treated with endoscopic vacuum therapy for clinically relevant anastomotic leak. MAIN OUTCOME MEASURES Treatment success (sepsis control, granulation and closure of the leak cavity, and no subsequent interventional or surgical procedure required); treatment duration; complications associated with endoscopic vacuum therapy; outpatient treatment; and restoration of intestinal continuity in diverted patients. RESULTS Fifty-seven patients were included. In 20 patients (35%), endoscopic vacuum therapy was initiated without secondary diversion since the leak was extraperitoneal, and the sponge could be placed into the leak cavity with an adequate seal toward the lumen. In 18 patients (90%), this approach was successful. None of these patients required subsequent diversion in the further course of their disease. In two patients, secondary diversion was necessary due to treatment failure. Balloon dilatation for luminal stenosis was required in two patients. When comparing patient and treatment characteristics of patients with and without a stoma, including treatment success and duration, no significant differences were found. Restoration of intestinal continuity was achieved in 69% of diverted patients. LIMITATIONS Unrandomized, retrospective study design; confounding factors of treatment assignment; low patient numbers and short follow-up of diverted patients; and low statistical power. CONCLUSION In this single-institution study, endoscopic vacuum therapy for rectal anastomotic leak was successful in 90% of patients without diversion with regard to sepsis control, granulation of the leak cavity, avoidance of surgery, and long-term stoma-free survival.

En 20 pacientes (35%), se inició la terapia endoscópica por aspiración al vacío sin derivación secundaria, ya que la fuga era extraperitoneal y la esponja podía colocarse en la cavidad de la fuga con un sellado adecuado hacia el lumen. En 18 pacientes (90%), este enfoque fue exitoso. Ninguno de estos pacientes requirió una derivación posterior durante la evolución de la enfermedad. En dos pacientes, fue necesaria una derivación secundaria debido al fracaso del tratamiento. Se requirió dilatación con balón por estenosis luminal en dos pacientes. Al comparar las características de los pacientes y del tratamiento con y sin ostomía, incluido el éxito y la duración del tratamiento, no se encontraron diferencias significativas. El restablecimiento de la continuidad intestinal se logró en el 69% de los pacientes derivados.LIMITACIONES:Diseño de estudio retrospectivo no aleatorio; factores de confusión en la asignación del tratamiento; escaso número de pacientes y seguimiento a corto plazo de los pacientes ostomizados; bajo poder estadístico.CONCLUSIÓN:En este estudio de una sola institución, la terapia al vacío por vía endoscópica en casos de fuga anastomótica rectal fue exitosa en el 90% de los pacientes sin derivación con respecto al control de la sepsis, granulación de la cavidad de la fuga, como se evitó la cirugía y la sobrevida sin ostomía a largo plazo.

Use of double-layered covered esophageal stents in post-surgical esophageal leaks and esophageal perforation: Our experience. GASTROENTEROLOGIA Y HEPATOLOGIA 2022; 45:198-203. [PMID: 34052404 DOI: 10.1016/j.gastrohep.2021.04.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/11/2021] [Revised: 04/02/2021] [Accepted: 04/14/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION The use of esophageal stents for the endoscopic management of esophageal leaks and perforations has become a usual procedure. One of its limitations is its high migration rate. To solve this incovenience, the double-layered covered esophageal stents have become an option. OBJECTIVES To analyse our daily practice according to the usage of double-layered covered esophageal metal stents (DLCEMS) (Niti S™ DOUBLE™ Esophageal Metal Stent Model) among patients diagnosed of esophageal leak or perforation. METHODS Retrospective, descriptive and unicentric study, with inclusion of patients diagnosed of esophageal leak or perforation, from November 2010 until October 2018. The main aim is to evaluate the efficacy of DLCEMS, in terms of primary success and technical success. The secondary aim is to evaluate their (the DLCEMS) safety profile. RESULTS Thirty-one patients were firstly included. Among those, 8 were excluded due to mortality not related to the procedure. Following stent placement, technical success was reached in 100% of the cases, and primary success, in 75% (n=17). Among the complications, stent migration was present in 21.7% of the patients (n=5), in whom the incident was solved by endoscopic means. CONCLUSIONS According to our findings, DLCEMS represent an alternative for esophageal leak and perforation management, with a high success rate in leak and perforation resolutions and low complication rate, in contrast to the published data. The whole number of migrations were corrected by endoscopic replacement, without the need of a new stent or surgery.

Anastomotic leakage in colorectal cancer surgery. Surg Oncol 2022; 40:101708.

Abstract
The safety of colorectal surgery for oncological disease is steadily improving, but anastomotic leakage is still the most feared and devastating complication from both a surgical and oncological point of view. Anastomotic leakage affects the outcome of the surgery, increases the times and costs of hospitalization, and worsens the prognosis in terms of short- and long-term outcomes. Anastomotic leakage has a wide range of clinical features ranging from radiological only finding to peritonitis and sepsis with multi-organ failure. C-reactive protein and procalcitonin have been identified as early predictors of anastomotic leakage starting from postoperative day 2-3, but abdominal-pelvic computed tomography scan is still the gold standard for the diagnosis. Several treatments can be adopted for anastomotic leakage. However, there is not a universally accepted flowchart for the management, which should be individualized based on patient's general condition, anastomotic defect size and location, indication for primary resection and presence of the proximal stoma. Non-operative management is usually preferred in patients who underwent proximal faecal diversion at the initial operation. Laparoscopy can be attempted after minimal invasive surgery and can reduce surgical stress in patients allowing a definitive treatment. Reoperation for sepsis control is rarely necessary in those patients who already have a diverting stoma at the time of the leak, especially in extraperitoneal anastomoses. In patients without a stoma who do not require abdominal reoperation for a contained pelvic leak, there are several treatment options, including laparoscopic diverting ileostomy combined with trans-anal anastomotic tube drainage, percutaneous drainage or recently developed endoscopic procedures, such as stent or clip placement or endoluminal vacuum-assisted therapy. We describe the current approaches to treat this complication, as well as the clinical tests necessary to diagnose and provide an effective therapy.

Abstract
OBJECTIVE This study aimed to characterize rates and management of anastomotic leak (AL) and conduit necrosis (CN) after esophagectomy in an international cohort. BACKGROUND Outcomes in patients with anastomotic complications of esophagectomy are currently uncertain. Optimum strategies to manage AL/CN are unknown, and have not been assessed in an international cohort. METHODS This prospective multicenter cohort study included patients undergoing esophagectomy for esophageal cancer between April 2018 and December 2018 (with 90 days of follow-up). The primary outcomes were AL and CN, as defined by the Esophageal Complications Consensus Group. The secondary outcomes included 90-day mortality and successful AL/CN management, defined as patients being alive at 90 day postoperatively, and requiring no further AL/CN treatment. RESULTS This study included 2247 esophagectomies across 137 hospitals in 41 countries. The AL rate was 14.2% (n = 319) and CN rate was 2.7% (n = 60). The overall 90-day mortality rate for patients with AL was 11.3%, and increased significantly with severity of AL (Type 1: 3.2% vs. Type 2: 13.2% vs. Type 3: 24.7%, P < 0.001); a similar trend was observed for CN. Of the 329 patients with AL/CN, primary management was successful in 69.6% of cases. Subsequent rounds of management lead to an increase in the rate of successful treatment, with cumulative success rates of 85.4% and 88.1% after secondary and tertiary management, respectively. CONCLUSION Patient outcomes worsen significantly with increasing AL and CN severity. Reintervention after failed primary anastomotic complication management can be successful, hence surgeons should not be deterred from trying alternative management strategies.

Abstract
BACKGROUND Endoscopic vacuum therapy (EVT) is an effective treatment option for leakage of the upper gastrointestinal (UGI) tract. The aim of this study was to evaluate the clinical impact of quality improvements in EVT management on patients' outcome. METHODS All patients treated by EVT at our center during 2012-2021 were divided into two consecutive and equal-sized cohorts (period 1 vs. period 2). Over time several quality improvement strategies were implemented including the earlier diagnosis and EVT treatment and technical optimization of endoscopy. The primary endpoint was defined as the composite score MTL30 (mortality, transfer, length-of-stay > 30 days). Secondary endpoints included EVT efficacy, complications, in-hospital mortality, length-of-stay (LOS) and nutrition status at discharge. RESULTS A total of 156 patients were analyzed. During the latter period the primary endpoint MTL30 decreased from 60.8 to 39.0% (P = .006). EVT efficacy increased from 80 to 91% (P = .049). Further, the need for additional procedures for leakage management decreased from 49.9 to 29.9% (P = .013) and reoperations became less frequent (38.0% vs.15.6%; P = .001). The duration of leakage therapy and LOS were shortened from 25 to 14 days (P = .003) and 38 days to 25 days (P = .006), respectively. Morbidity (as determined by the comprehensive complication index) decreased from 54.6 to 46.5 (P = .034). More patients could be discharged on oral nutrition (70.9% vs. 84.4%, P = .043). CONCLUSIONS Our experience confirms the efficacy of EVT for the successful management of UGI leakage. Our quality improvement analysis demonstrates significant changes in EVT management resulting in accelerated recovery, fewer complications and improved functional outcome.

Abstract
INTRODUCTION Endoscopic drainage should preferably be tried unless the abscess caused by the anastomotic leak is generalized and disseminated into the abdominal cavity. The aim of this study was to evaluate the results of patients treated with EndoVac. PATIENT AND METHODS The medical records of patients who underwent low anterior resection and were treated using the EndoVac therapy system due to the detection of an anastomotic leak were retrospectively evaluated. RESULTS Thirty-three of the patients with detection of anastomotic leaks were treated using EndoVac therapy system. The mean number of application of the EndoVac therapy system was 5.8 (1 to 12) for each patient. Mean duration of hospitalization of the patients was 24.5 (9 to 92) days. Five patients underwent a second operation during the follow-up period after application of the EndoVac therapy system. In our study, the number of patients recovering without the need for additional treatment is 30 (30/33). Our success rate was 90.1%. CONCLUSIONS The EndoVac therapy system is an alternative and helpful system in the treatment of colorectal anastomotic leaks without reoperation needed. It can also prevent permanent stoma.

Abstract
Anastomotic leakage is one of the most severe complications after esophagectomy and is associated with increased postoperative morbidity and mortality. Several projects ranging from small retrospective studies to large collaborations have aimed to identify potential pre- and perioperative risk factors and to improve the diagnostic processes and management. Despite the increase in available literature, many aspects of anastomotic leakage are still debated, without the existence of widely accepted guidelines. The purpose of this review is to provide a cutting edge overview of the recent literature regarding the definition and classification of anastomotic leakage, risk factors, novel diagnostic modalities, and emerging therapeutic options for treatment and prevention of anastomotic leakage following esophagectomy.

Abstract
BACKGROUND Anastomotic leakage after rectal resection represents a severe complication for the patient and requires an early and appropriate management. Endoscopic vacuum therapy (EVT) has become the treatment of choice for anastomotic leakage after rectal resection in several institutions in Germany, and commercially available systems are currently distributed in approximately 30 countries worldwide. However, there is no evidence that EVT is superior to any other treatment for anastomotic leakage after rectal resection. METHODS Twenty-one patients treated with EVT for anastomotic leakage after rectal resection were retrospectively compared to a historical cohort of 41 patients that received conventional treatment. Primary endpoints were death, treatment success and long-term preservation of intestinal continuity. Secondary endpoints were length of hospital stay and duration of treatment. RESULTS There was no difference in mortality (p = 0.624). The intention-to-treat analysis showed a significantly higher success rate of EVT compared to conventional treatment (95.2% vs. 65.9%, p = 0.011). EVT was associated with preservation of intestinal continuity in a significant higher percentage of patients than patients undergoing conventional treatment (86.7% vs. 37.5%, p = 0.001). Conventional treatment tended to a shorter length of hospital stay (31.1 vs. 42.2 days, p = 0.066) but with no difference in overall duration of treatment. Time until closing of a diverting stoma did not differ between groups (10.2 months in the EVT group vs. 9.4 months in the conventional treatment group, p = 0.721). CONCLUSION According to this retrospective study, conventional therapy and EVT are both options for the treatment of anastomotic leakage after rectal resection. EVT might be more effective in terms of definite healing and preservation of intestinal continuity.

Abstract
INTRODUCTION Endoscopic placement of oesophageal stents may be used in benign oesophageal perforation and oesophageal anastomotic leakage to control sepsis and reduce mortality and morbidity by avoiding thoracotomy. This updated systematic review aimed to assess the safety and effectiveness of oesophageal stents in these two scenarios. METHODS A systematic literature search of all published studies reporting use of metallic and plastic stents in the management of post-operative anastomotic leaks, spontaneous and iatrogenic oesophageal perforations were identified. Primary outcomes were technical (deploying ≥ 1 stent to occlude site of leakage with no evidence of leakage of contrast within 24-48 h) and clinical success (complete healing of perforation or leakage by placement of single or multiple stents irrespective of whether the stent was left in situ or was removed). Secondary outcomes were stent migration, perforation and erosion, and mortality rates. Subgroup analysis was performed for plastic versus metallic stents and anastomotic leaks versus perforations separately. RESULTS A total of 66 studies (n = 1752 patients) were included. Technical and clinical success rates were 96% and 87%, respectively. Plastic stents had significantly higher migration rates (24% vs 16%, p = 0.001) and repositioning (11% vs 3%, p < 0.001) and lower technical success (91% vs 95%, p = 0.032) than metallic stents. In patients with anastomotic leaks, plastic stents were associated with higher stent migration (26% vs 15%, p = 0.034), perforation (2% vs 0%, p = 0.013), repositioning (10% vs 0%, p < 0.001), and lower technical success (95% vs 100%, p = p = 0.002). In patients with perforations only, plastic stents were associated with significantly lower technical success (85% vs 99%, p < 0.001). CONCLUSIONS Covered metallic oesophageal stents appear to be more effective than plastic stents in the management of oesophageal perforation and anastomotic leakage. However, quality of evidence of generally poor and high-quality randomised trial is needed to further evaluate best management option for oesophageal perforation and anastomotic leakage.

Abstract
INTRODUCTION The incidence of anastomotic leak (AL) has not decreased over the past decades and some important grey areas remain in its definition, prevention, and management. The aim of this study was to reach a national consensus on the definition of AL and to identify key points to be applied in clinical practice. METHODS A 3-step modified Delphi method was used to establish consensus. Ten representative members of the major Italian surgical scientific societies with proven colorectal expertise were selected after a call to action. After a comprehensive literature search, each expert drew a list of evidence-based statements which were voted in round one by the scientific board. Panel members were asked to mark "totally disagree", "partially agree" or "totally agree" for each statement and provide comments. The same voting method was used for round 2. Round 3 consisted of a final face-to-face meeting. RESULTS Thirty-three statements (clustered into 14 topics) were included in round 1. Following the third voting round, a final list of 16 items was formulated, which encompass the following 9 topics: AL definition, patient- and operative-related risk factors, prevention measures, bowel preparation, surgical technique, intraoperative assessment, early diagnosis, radiological diagnosis and management of specific patterns of AL. The overall response rate was 100% for all items in all the three rounds. CONCLUSIONS This Delphi survey identified items that expert colorectal surgeons agreed were important to be applied in the prevention, diagnosis, and management of AL. This represents the first consensus involving all relevant national scientific societies, defining important and shared concepts in the diagnosis and management of AL.

Abstract
INTRODUCTION Indocyanine green (ICG) fluorescent angiography has been routinely applied for various laparoscopic procedures to evaluate the tissue blood supply. A promising branch for this technology is represented by bariatric surgery, especially to estimate the risk of gastric leak after laparoscopic sleeve gastrectomy (LSG), which seems mainly related to ischemia of the stomach. MATERIALS AND METHODS 43 consecutive patients from January 2018 to March 2019 underwent in our institution LSG with intravenous injection of 5 ml ICG after the realization of gastric tube to evaluate the blood supply of the gastric tube. RESULTS In all 43 cases, there have been no adverse events related to ICG. The vascular supply to stomach was estimated "satisfactory" along the stapled line in all cases. However, one patient showed signs and symptoms indicative of gastric leak in the fifth post-op day and diagnosis was confirmed by CT scan with Gastrografin. CONCLUSIONS From our preliminary data, the intraoperative view of the blood supply of the stomach does not seem to represent a prognostic factor for the risk of gastric leak, suggesting a complex multifactorial etiology (intragastric hypertension? Abnormal inflammatory response?) which needs further data to be established.

Abstract
BACKGROUND Anastomotic leaks are associated with significant risk of morbidity, mortality and treatment costs after oesophagectomy. The aim of this study was to evaluate international variation in unit-level clinical practice and resource availability for the prevention and management of anastomotic leak following oesophagectomy. METHOD The Oesophago-Gastric Anastomosis Audit (OGAA) is an international research collaboration focussed on improving the care and outcomes of patients undergoing oesophagectomy. Any unit performing oesophagectomy worldwide can register to participate in OGAA studies. An online unit survey was developed and disseminated to lead surgeons at each unit registered to participate in OGAA. High-income country (HIC) and low/middle-income country (LMIC) were defined according to the World Bank whilst unit volume were defined as < 20 versus 20-59 versus ≥60 cases/year in the unit. RESULTS Responses were received from 141 units, a 77% (141/182) response rate. Median annual oesophagectomy caseload was reported to be 26 (inter-quartile range 12-50). Only 48% (68/141) and 22% (31/141) of units had an Enhanced Recovery After Surgery (ERAS) program and ERAS nurse, respectively. HIC units had significantly higher rates of stapled anastomosis compared to LMIC units (66 vs 31%, p = 0.005). Routine post-operative contrast-swallow anastomotic assessment was performed in 52% (73/141) units. Stent placement and interventional radiology drainage for anastomotic leak management were more commonly available in HICs than LMICs (99 vs 59%, p < 0.001 and 99 vs 83%, p < 0.001). CONCLUSIONS This international survey highlighted variation in surgical technique and management of anastomotic leak based on case volume and country income level. Further research is needed to understand the impact of this variation on patient outcomes.

Abstract
BACKGROUND AND AIMS Postoperative esophageal leaks are one of the major causes of postoperative mortality and morbidity. The purpose of this study was to review current knowledge of current methods of diagnosis and management of postoperative esophageal leaks. Methods: A systematic literature search was performed in the PubMed/Medline database using the terms "postoperative esophageal leaks" and "postesophagectomy complications" to identify articles relevant to the current diagnostic and prophylactic and curative treatment of post-oesophagectomy anastomotic fistulas. Results: Several papers have shown that the incidence of fistulas varies and is dependent on several factors: the location of the anastomosis, the type of suture used, the biological condition of the patient. Due to the severity of the mediastinal anastomotic fistula, great importance is being given to the methods of preventing its occurrence by intraoperative testing or improving the gastric tube vascularity. The most recent articles present endoscopic methods of treating this complication by using coated esophageal stents and endoluminal vacuum therapy. CONCLUSION In patients with mediastinal postoperative esophageal fistulas, diagnosis and management represent a real challenge for the surgeon-endoscopist-therapist team. The early diagnosis and the establishment of an optimal therapy to address the parietal defect and the biological status of the patient are mandatory conditions for resolving this postoperative complication.

Abstract
Persisting suture dehiscence with oesophageal anastomotic leaks after thoracic surgery is a difficult complication, especially when a surgical repair fails. We report here endoscopic vacuum-assisted closure therapy as a novel endoscopic treatment for the management of oesophageal anastomotic leaks. Endoscopic vacuum-assisted closure therapy is a minimally invasive method to treat anastomotic leakage by positioning an open-pored polyurethane sponge and a suction tube connected to a wound drainage system into the opening of the wound cavity. This multidisciplinary endoscopic and surgical approach is a successful therapy for the management of suture dehiscence with oesophageal anastomotic leaks after thoracic surgery or oesophageal perforations.

Abstract
The ileal pouch anal anastomosis (IPAA) has revolutionised the surgical management of ulcerative colitis (UC) and familial adenomatous polyposis (FAP). Despite refinement in surgical technique(s) and patient selection, IPAA can be associated with significant morbidity. As the IPAA celebrated its 40th anniversary in 2018, this review provides a timely outline of its history, indications, and complications. IPAA has undergone significant modification since 1978. For both UC and FAP, IPAA surgery aims to definitively cure disease and prevent malignant degeneration, while providing adequate continence and avoiding a permanent stoma. The majority of patients experience long-term success, but “early” and “late” complications are recognised. Pelvic sepsis is a common early complication with far-reaching consequences of long-term pouch dysfunction, but prompt intervention (either radiological or surgical) reduces the risk of pouch failure. Even in the absence of sepsis, pouch dysfunction is a long-term complication that may have a myriad of causes. Pouchitis is a common cause that remains incompletely understood and difficult to manage at times. 10% of patients succumb to the diagnosis of pouch failure, which is traditionally associated with the need for pouch excision. This review provides a timely outline of the history, indications, and complications associated with IPAA. Patient selection remains key, and contraindications exist for this surgery. A structured management plan is vital to the successful management of complications following pouch surgery.

Abstract
Esophageal anastomotic leakage (EAL) is a devastating complication for esophagectomy but the available therapies are unsatisfactory. Due to the healing effects of mesenchymal stromal cells (MSCs) and supporting capability of fibrin scaffold (FS), we evaluated the efficacy of a stem-cell therapy for EAL by engrafting adult and autologous MSCs (AAMSCs) in FS and investigated the potential mechanism. Twenty-one rabbits were assigned to AAMSC/FS group (n = 12) and control group (n = 9). After harvested, AAMSCs were identified and then labeled with lenti.GFP. To construct EAL model, a polyethylene tube was indwelled through the anastomosis for 1 week. A total of 2 × 106 AAMSCs in 0.2 ml FS were engrafted onto the EAL for the AAMSC/FS group, whereas FS was injected for control. Magnetic Resonance Imaging (MRI) examination was performed after 5 weeks. Esophageal tissues were harvested for macroscopic, histological analyses, Western blot, and immunohistochemistry at 8 weeks. The animal model of EAL was established successfully. MRI scanning revealed a decreased inflammation reaction in AAMSC/FS group. Accordingly, AAMSC/FS group presented a higher closure rate (83.3% vs. 11.1%, p = .02) and lower infection rate (33.3% vs. 88.9%, p = .02). Histological analyses showed the autografted MSCs resided in the injection site. Furthermore, milder inflammation responses and less collagen deposition were observed in AAMSC/FS group. Western blot and immunohistochemistry studies suggested that the therapeutic effect might be related to the secretions of IL-10 and MMP-9. Engrafting AAMSCs in FS could be a promising therapeutic strategy for the treatment of EAL by suppressing inflammation response and alleviating fibrosis progression.

Abstract
BACKGROUND Mediastinal leakage (ML) is one of the most feared complications of esophagectomy. A standard strategy for its diagnosis and treatment has been difficult to establish because of the great variability in their incidence and mortality rates reported in the existing series.
AIM To assess the incidence, predictive factors, treatment, and associated mortality rate of mediastinal leakage using the standardized definition of mediastinal leaks recently proposed by the Esophagectomy Complications Consensus Group (ECCG).
METHODS Seven Italian surgical centers (five high-volume, two low-volume) affiliated with the Italian Society for the Study of Esophageal Diseases designed and implemented a retrospective study including all esophagectomies (n = 501) with intrathoracic esophagogastric anastomosis performed from 2014 to 2017. Anastomotic MLs were defined according to the classification recently proposed by the ECCG.
RESULTS Fifty-nine cases of ML were recorded, yielding an overall incidence of 11.8% (95%CI: 9.1%-14.9%). The surgical approach significantly influenced the occurrence of ML: the proportion of leakage was 10.5% and 9% after open and hybrid esophagectomy (HE), respectively, and doubled (20%) after totally minimally invasive esophagectomy (TMIE) (P = 0.016). No other predictive factors were found. The 30- and 90-d overall mortality rates were 1.4% and 3.2%, respectively; the 30- and 90-d leak-related mortality rates were 5.1% and 10.2%, respectively; the 90-d mortality rates for TMIE and HE were 5.9% and 1.8%, respectively. Endoscopy was the first-line treatment in 49% of ML cases, with the need for retreatment in 17.2% of cases. Surgery was needed in 44.1% of ML cases. Endoscopic treatment had the lowest mortality rate (6.9%). Removal of the gastric tube with stoma formation was necessary in 8 (13.6%) cases.
CONCLUSION The incidence of ML after esophagectomy was high mainly in the TMIE group. However, the general and specific (leak-related) mortality rates were low. Early treatment (surgical or endoscopic) of severe leaks is mandatory to limit related mortality.

Novel abdominal negative pressure lavage-drainage system for anastomotic leakage after R0 resection for gastric cancer. World J Gastroenterol 2019; 25:258-268. [PMID: 30670914 PMCID: PMC6337017 DOI: 10.3748/wjg.v25.i2.258] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/31/2018] [Revised: 12/09/2018] [Accepted: 12/20/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Anastomotic leakage (AL) is a severe complication associated with high morbidity and mortality after radical gastrectomy (RG) for gastric cancer (GC). We hypothesized that a novel abdominal negative pressure lavage-drainage system (ANPLDS) can effectively reduce the failure-to-rescue (FTR) and the risk of reoperation, and it is a feasible management for AL.
AIM To report our institution’s experience with a novel ANPLDS for AL after RG for GC.
METHODS The study enrolled 4173 patients who underwent R0 resection for GC at our institution between June 2009 and December 2016. ANPLDS was routinely used for patients with AL after January 2014. Characterization of patients who underwent R0 resection was compared between different study periods. AL rates and postoperative outcome among patients with AL were compared before and after the ANPLDS therapy. We used multivariate analyses to evaluate clinicopathological and perioperative factors for associations with AL and FTR after AL.
RESULTS AL occurred in 83 (83/4173, 2%) patients, leading to 7 deaths. The mean time of occurrence of AL was 5.6 days. The AL rate was similar before (2009-2013, period 1) and after (2014-2016, period 2) the implementation of the ANPLDS therapy (1.7% vs 2.3%, P = 0.121). Age and malnourishment were independently associated with AL. The FTR rate and abdominal bleeding rate after AL occurred were respectively 8.4% and 9.6% for the entire period; however, compared with period 1, this significantly decreased during period 2 (16.2% vs 2.2%, P = 0.041; 18.9% vs 2.2%, P = 0.020, respectively). Moreover, the reoperation rate was also reduced in period 2, although this result was not statistically significant (13.5% vs 2.2%, P = 0.084). Additionally, only ANPLDS therapy was an independent protective factor for FTR after AL (P = 0.04).
CONCLUSION Our experience demonstrates that ANPLDS is a feasible management for AL after RG for GC.

Self-Expanding Metal Stents Versus Endoscopic Vacuum Therapy in Anastomotic Leak Treatment After Oncologic Gastroesophageal Surgery. J Gastrointest Surg 2019; 23:67-75. [PMID: 30374816 DOI: 10.1007/s11605-018-4000-x] [Citation(s) in RCA: 45] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2018] [Accepted: 09/28/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND Anastomotic leak after gastroesophageal surgery is a life-threatening complication. Self-expanding metal stent (SEMS) implantation or endoscopic vacuum therapy (EVT) have been established as alternatives to reoperation. This study compares the outcome of both interventions for anastomotic leak clinical management. METHODS In this retrospective study, we identified all patients who received SEMS or EVT for anastomotic leaks after oncological gastroesophageal surgery between January 2007 and December 2016. Only patients with type II leaks according to the Esophagectomy Complications Consensus Group were included. Sealing rates, intervention-related complications, demographic characteristics, clinical history, leak characteristics, therapy duration, and in-hospital mortality were analyzed. RESULTS One hundred eleven patients who received SEMS (n = 76) or EVT (n = 35) were identified and categorized by primary and final treatment. The overall closure rate in the final treatment analysis was 85.7% for EVT and 72.4% for SEMS (p = 0.152). ICU stay ranged from 0 to 60 days (median 6 days) for EVT and from 0 to 295 days (median 9 days) for SEMS (p = 0.704). EVT patients were hospitalized for 19-119 days (median 39 days) and SEMS patients for 13-296 days (median 37 days; p = 0.812). Demographic factors, comorbidities, and surgical parameters did not correlate with treatment or treatment success. CONCLUSIONS SEMS and EVT show comparable results for anastomotic leak management after oncologic gastroesophageal surgery. No superior outcome could be found for either one of the two treatments options.

Esophagojejunal anastomotic leakage following gastrectomy for gastric cancer. Surg Today 2018; 49:187-196.

Abstract
Esophagojejunal anastomotic leakage (EJAL) is a serious complication of total or proximal gastrectomy for gastric cancer, with a reported incidence of 2.1-14.6% and mortality of up to 50%. EJAL is an independent prognostic factor for the poor survival of gastric cancer patients. Meticulous surgical techniques, experience with anastomotic devices, and a thorough understanding of various risk factors and preventive measures are essential and early diagnosis is critical for preventing EJAL-related death. Patients with suspected EJAL must be evaluated promptly, but contrast swallow is not recommended. There is no standard treatment strategy for EJAL, although conservative treatment with drainage and nutritional support is the most common approach. Effective endoscopic treatments have been reported but need further validation. Surgical treatment is associated with high mortality but should be considered to prevent death from suboptimal EJAL management, for patients with severe sepsis or when conservative treatment has failed.

Regulating migration of esophageal stents - management using a Sengstaken-Blakemore tube: A case report and review of literature. World J Gastroenterol 2018; 24:3192-3197. [PMID: 30065565 PMCID: PMC6064967 DOI: 10.3748/wjg.v24.i28.3192] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2018] [Revised: 06/17/2018] [Accepted: 06/27/2018] [Indexed: 02/06/2023] Open
Abstract
Stent migration, which causes issues in stent therapy for esophageal perforations, can counteract the therapeutic effects and lead to complications. Therefore, techniques to regulate stent migration are important and lead to effective stent therapy. Here, in these cases, we placed a removable fully covered self-expandable metallic stent (FSEMS) in a 52-year-old man with suture failure after surgery to treat Boerhaave syndrome, and in a 53-year-old man with a perforation in the lower esophagus due to acute esophageal necrosis. At the same time, we nasally inserted a Sengstaken-Blakemore tube (SBT), passing it through the stent lumen. By inflating a gastric balloon, the lower end of the stent was supported. When the stent migration was confirmed, the gastric balloon was lifted slightly toward the oral side to correct the stent migration. In this manner, the therapy was completed for these two patients. Using a FSEMS and SBT is a therapeutic method for correcting stent migration and regulating the complete migration of the stent into the stomach without the patient undergoing endoscopic rearrangement of the stent. It was effective for positioning a stent crossing the esophagogastric junction.

Abstract
Surgical sealants have been used in thoracic surgery in an effort to reduce air leak duration, intercostal drain duration, length of stay and complications. They are instilled over a defect usually treated with other means. We herein present the technique of controlling a difficult to treat defect by directly instilling Bioglue™ alone into a crater, caused during empyema Video-assisted thoracic surgery in a 50-year-old patient with a trapped lung. This deep crater had caused a significant air leak rendering intraoperative ventilation challenging. After instillation, the dependent lung was kept blocked. With this technique, the Bioglue™ polymerized and the air leak was dramatically decreased making ventilation and eventually extubation of the patient feasible. Instillation of Bioglue™ directly into a large lung defect could be a choice of action to decrease complicated air leaks, otherwise impossible to treat with other means, in patients with trapped lung.

A pilot study of endoscopically inserted biodegradable biliary stents in the treatment of benign biliary strictures and cystic duct leaks. Gastrointest Endosc 2018; 87:1132-1137. [PMID: 29128386 DOI: 10.1016/j.gie.2017.10.042] [Citation(s) in RCA: 26] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2017] [Accepted: 10/23/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Self-expanding biodegradable biliary stents (BDBSs) have recently become available for use in endoscopic retrograde cholangiography (ERC). The aim was to evaluate the effectiveness and safety of novel BDBSs in iatrogenic cystic duct leaks and benign biliary strictures (BBSs). METHODS Patients providing informed consent were recruited for the prospective study. Braided self-expanding poly-dioxanone BDBSs were inserted using ERC during from 2014 to 2016. Repeated liver function tests and magnetic resonance imaging were performed during follow-up. The main outcomes were treatment success and adverse events. RESULTS Thirteen patients, 5 women, median age 67 years (range, 43-79) underwent BDBS insertion for iatrogenic cystic duct leak (n = 7) or BBS (n = 6). Stent insertion using ERC was successful in all cases. All bile leaks were treated uneventfully with BDBSs. In BBSs, the clinical success rate of BDBS therapy was 83% in a median of 21 months of follow-up (range, 14-25). Early ERC-related adverse events included 1 cholangitis (8%) and 1 pancreatitis (8%), both in the stricture group. During the first 90 days, 23% of patients were readmitted for mild cholangitis. CONCLUSIONS The short- and long-term safety of endoscopically inserted poly-dioxanone BDBSs was satisfactory. The management of cystic duct leaks and benign distal common bile duct strictures was highly successful. Episodes of mild cholangitis during stent indwelling seemed to be typical of BDBSs. The advantage of BDBSs is the avoidance of repeated endoscopy for stent removal. (Clinical trial registration number: NCT02353286.).

Abstract
BACKGROUND AND OBJECTIVES Endoscopic stenting is a minimally invasive treatment modality for patients with various gastrointestinal conditions. We evaluated the safety and efficacy of uncovered biodegradable stents for postoperative leaks and strictures in the upper gastrointestinal tract. METHODS This was a retrospective study of patients treated endoscopically with biodegradable stents from January 2010 through November 2017. RESULTS Thirteen patients were enrolled, 7 of whom were men. Their mean age was 46 (range, 21-82) years. The indications for stent placement were postoperative leakage and stricture in 9 and 4 patients, respectively. The primary diagnoses were obesity in 7 patients, gastric cancer in 5, and peptic ulcer in 1. The average time to stent placement after surgery was 35 (range, 17-125) and 166 (range, 153-185) days for patients with postoperative leakage and stricture, respectively. Stent insertion was successful at the first attempt in all patients. Complete resolution of the leak and stricture was achieved after stent application in 11 patients, for a clinical success rate of 85%. The mean follow-up duration was 50 (range, 24-76) months. There were no major complications. CONCLUSIONS Compared to self-expanding metal and plastic stents, the main advantages of uncovered biodegradable stents are that they do not have to be removed and have a low migration rate. Our results suggest that these stents have promise for management of postoperative gastrointestinal complications. Further randomized trials with larger sample sizes are necessary to determine the role of biodegradable stents in the treatment algorithm.

Abstract
BACKGROUND Perforations and anastomotic leaks of the gastrointestinal tract are severe complications, which carry high morbidity and mortality and management of these is a multi-disciplinary challenge. The use of endoluminal vacuum (EVAC) therapy has recently proven to be a useful technique to manage these complications. We report our institution's experience with this novel technique in the chest, abdomen, and pelvis. METHODS This is a retrospective review of an IRB approved registry of all EVAC therapy patients from July 2013 to December 2016. A total of 55 patients were examined and 49 patients were eligible for inclusion: 15 esophageal, 21 gastric, 3 small bowel, and 10 colorectal defects. The primary endpoint was closure rate of the GI tract defect with EVAC therapy. RESULTS Fifteen (100%) esophageal defects closed with EVAC therapy. Mean duration of therapy was 27 days consisting of an average of 6 endosponge changes every 4.8 days. Eighteen (86%) gastric defects closed with EVAC therapy. Mean duration of therapy was 38 days with a mean of 9 endosponge changes every 5.3 days. Three (100%) small bowel defects closed with EVAC therapy. Mean duration of therapy was 13.7 days with a mean of 2.7 endosponge changes every 4.4 days. Six (60%) colorectal defects closed with EVAC therapy. Mean duration of therapy was 23.2 days, consisting of a mean of 6 endosponge changes every 4.0 days. There were two deaths, which were not directly related to EVAC therapy and occurred outside the measured 30-day mortality. CONCLUSION Our experience demonstrates that EVAC therapy is feasible and effective for the management of gastrointestinal perforations/leaks throughout the GI tract and can be considered as a safe alternative to surgical intervention in select cases.

Abstract
OBJECTIVE To evaluate the efficacy of self-made gasbag double-cannula stool drainage device for prevention of anastomotic leakage following anterior resection. METHODS Clinical data of 169 rectal cancer patients in the 8th Affiliated Hospital of Sun Yat-sen University between October 2010 and October 2016 were retrospectively analyzed. Among them, a self-made gasbag double-cannula stool drainage device was placed in 71 patients(stool drainage group), and the remaining 98 patients were taken as control. After an anastomosis, the drainage device was transanally placed by the assistant and the distal tube of drainage device was stretched more than 15 cm from anastomosis. The gasbag was inflated to fully expand the intestine. The main tube was fixed on perianal skin with 7-0 suture, kept more than 3-5 cm outside the anus, and connected to the drainage bag. The incidence of anastomotic leakage was compared between the two groups. RESULTS The baseline data were similar between the two groups (all P>0.05). The differences in operative time, intraoperative blood loss, and time to bowel function recovery were not statistically significant (all P>0.05), however, time to oral intake and postoperative stay were shorter in stool drainage group as compared to the control group (both P<0.05). There was no perioperative death in both groups. In stool drainage group, there were 6 cases whose drainage device was pulled out within 48 hours due to intolerance. The ruptured gasbag was replaced 5 times and the tube was clogged by fecal material 21 times. After flushing, the tube did not recanalized and was pulled out in 3 cases. The incidence of anastomotic leakage in stool drainage group was significantly lower than that in the control group (2.8% vs. 11.2%, P=0.043). As for the low anastomosis (the distance to anal verge less than 5 cm), the incidence of anastomotic leakage in stool drainage group was also significantly lower than that in the control group (2.3% vs. 15.4%, P=0.028), while as for the high anastomosis, the difference was not statistically significant (3.6% vs. 3.0%, P=0.906). Logistic regression analysis revealed that the presence of a stool drainage device was an independent protective factor for anastomotic leakage (OR=0.316, 95%CI:0.114 ~ 0.769, P=0.003). CONCLUSIONS The self-made gasbag double-cannula stool drainage device effectively prevents anastomotic leakage after anterior resection of rectal cancer. However it is not suitable for those patients with high anastomosis.

Abstract
A 65-year-old man with cT1bN0M0 stage I middle thoracic esophageal cancer underwent subtotal esophagectomy and gastric tube reconstruction through the posterior mediastinal route after preoperative carbon-ion radiotherapy and chemotherapy in a clinical trial. Anastomotic leakage occurred, but it spontaneously improved. At six months after the operation, he was rehospitalized with a cough and dysphagia. An esophago-bronchiole fistula and stenosis of the gastric tube were observed. He first underwent stent placement in the gastric tube. Two weeks later, the syringeal epithelium was burned by argon plasma coagulation after stent removal. Endoscopic occlusion was then performed for the fistula with two guidewire-assisted silicone spigots. Two weeks later, he was discharged on an oral diet, and he has not developed recurrence of the fistula or cancer for three years. This is the first report of endoscopic occlusion with a guidewire-assisted silicone spigot through the esophagus.

Abstract
The intraoperative and postoperative air leakages in lung surgery are caused by factors related to patients as well as the surgical technique employed. Prevention and management of air leakage caused by these varied factors are essential for thoracic surgeons. The factors related to patients, such as severe emphysema, smoking history, and insufficient lobulation, should be evaluated before surgery. Although time-consuming, careful and reliable surgical techniques are required. After the lung surgery, management of drain is essential for controlling air leakage. Rethoracotomy is one of the treatment options that can be employed when conservative treatment does not improve the air leakage. At present, complete way of management of air leakage has not been established;therefore, thoracic surgeons should work toward developing a definite intraoperative and postoperative air leakage management in lung surgery.

Abstract
BACKGROUND Complications in colorectal surgery include a wide range of clinical conditions, which increase mortality, morbidity, hospital stay and costs. In some cases, the placement of a self-expanding metal stent may represent a possible therapeutic strategy, avoiding further surgery. METHODS In order to verify the feasibility and safety of the technique, we reviewed the medical literature, between January 1997 and 2015, selecting 32 studies. Inclusion criteria were based on Preferred Reporting Items for Systematic reviews and Meta-Analyses recommendations. RESULTS The estimated rate of early success was 73.3% (95% CI 66.3-79.3), raising from 25 to 68% in the time frame 1997-2007. The rate of early complications was 31.4% (95% CI 25.3-38.3%), progressively decreasing from 75 to 43% up to 2009. The rate of surgery for acute complication was 9.3% (95% CI 6.0-14.2%), reduced on time course from 25 to 9%. The rate of closure of dehiscence was 74.5% (95% CI 62.8-83.5%), while the rate of long-lasting success was 57.3% (95% CI 50.3-64.0%). CONCLUSIONS Endoscopic stenting in the early postoperative management of anastomotic complications after colorectal surgery should be considered in patients with minimal risk for sepsis, as a safe and often effective alternative to surgery. However, in order to establish the safety and efficacy of this technique, prospective studies involving a larger cohort of patients are required.

Abstract
The anastomotic complications following radical gastrectomy mainly include anastomotic leakage, anastomotic hemorrhage, and anastomotic stricture. Theanastomotic complications are not rare and remain the most common complications resulting in the perioperativedeath of patients with gastric cancer. Standardized training could let surgeons fully realize that strict selection of operative indications, thorough preoperative assessment and preparation, and refined operation in surgery are the essential measures to prevent the anastomotic complications following radical gastrectomy. In addition, identifying these complications timely and taking effective measures promptly according to the clinical context are the keys to treating these complications, reducing the treatment cycle, and decreasing the mortality.

Abstract
With the development of laparoscopic techniques and equipments, laparoscopic-assisted, even total laparoscopic radical surgery for gastric cancer can be performed successfully. However, the incidence of postoperative complications is higher in the laparoscopy group as compared to the open-surgery group, which is still the barrier for the total laparoscopic radical gastrectomy. Similar to open surgery, the major complications of digestive tract reconstruction after laparoscopic radical gastrectomy are anastomotic leakage, anastomotic bleeding, anastomotic stricture and stenosis of input or output loop. Moreover, due to the lack of tactile feedback and a narrow field of vision, the laparoscopic operation may be associated with complications due to technical reasons. In clinic, we tried to reduce the incidence of these complications by improving surgical skills and strengthening the perioperative treatment of patients. According to our experience, the complications mainly occur in the early stage, and with the cumulative experience, the complications can be effectively reduced.

Abstract
OBJECTIVE Given the current rate of obesity in the USA, it has been estimated that close to half of the US adult population could be obese by 2030, resulting in greater demand for bariatric procedures. Our objective was to analyze malpractice litigation related to bariatric surgery. METHODS We conducted a retrospective review of Westlaw (Thompson Reuters) of all bariatric operations that resulted in the filing of a malpractice claim. Each case was reviewed for pertinent medicolegal information related to the procedure, claim, and trial. RESULTS The search criteria yielded 298 case briefs, of which 140 met inclusion criteria. Thirty-two percent (n = 49) of cases involved male plaintiffs (patients). Mean patient age with standard deviation (SD) was 43 (10) years. The most common procedure litigated was the Roux-en-Y gastric bypass (76 %, n = 107). Overall, the most common alleged reason for a malpractice claim was delay in diagnosis or management of a complication in the postoperative period (n = 66, 47 %), the most common of which was an anastomotic leak (45 %, n = 34). Death was reported in 74 (52 %) cases. Fifty-seven cases (47 %) were decided in favor of the plaintiff (patient), with a median award payout of $1,090,000 (interquartile range [IQR] $412,500 to $2,550,000). CONCLUSION Delay in diagnosing or managing complications in the postoperative setting, most commonly an anastomotic leak, accounted for the majority of malpractice claims. Measures taken to identify and address anastomotic leaks and other complications early in the postoperative period could potentially reduce the amount of filed malpractice claims related to bariatric surgery.

Abstract
Postoperative peritonitis is still a life-threatening complication after abdominal surgery and approximately 10,000 patients annually develop postoperative peritonitis in Germany. Early recognition and diagnosis before the onset of sepsis has remained a clinical challenge as no single specific screening test is available. The aim of therapy is a rapid and effective control of the source of infection and antimicrobial therapy. After diagnosis of diffuse postoperative peritonitis surgical revision is usually inevitable after intestinal interventions. Peritonitis after liver, biliary or pancreatic surgery is managed as a rule by means of differentiated therapy approaches depending on the severity.

Experimental Study of Intraparenchymal Fibrinogen and Topical Thrombin to Seal Pleural Defects. THE TOKAI JOURNAL OF EXPERIMENTAL AND CLINICAL MEDICINE 2016; 41:185-189. [PMID: 27988916] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 07/13/2016] [Accepted: 08/04/2016] [Indexed: 06/06/2023]
Abstract
OBJECTIVE Fibrin sealants are used to close surgical pleural defects, but may detach, causing a postoperative air-leak. We investigated a new means of applying fibrin glue for closing pleural defects. METHODS Pleural defects (10-mm and 4-mm diameters, respectively) were created in swine and rats via thoracotomy. They were sealed by a) injection of a fibrinogen solution into the lung parenchyma after instillation of a thrombin solution onto the pleural defect (group A), b) fibrinogen and thrombin spray (group B), c) fibrinogen instillation and a thrombin-dipped polyglycolic acid sheet (group C), or d) fibrin glue-coated collagen fleece (group D). Resistance to airway pressure was compared and the sealed areas were histologically examined. RESULTS In group A, the minimum seal-breaking airway pressure was consistently > 40 cmH2O, versus 37.2 ± 3.6 cmH2O in group B, 37.2 ± 4.0 cmH2O in group C, and 39.0 ± 1.7 cmH2O in group D, which was statistically significant. Histologically, the fibrin layer infiltrated the lung parenchyma and covered the defect in group A, but not in the other groups. CONCLUSIONS The intraparenchymal injection of fibrinogen combined with instillation of thrombin created an effective fibrin layer associated with early pleural regeneration that reliably prevented pleural air leaks.

Intraoperative Dilatation and Air-Tight Testing of the Hepaticojejunostomy: A New Technique. J Coll Physicians Surg Pak 2016; 26:808-812. [PMID: 27806807] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2016] [Accepted: 09/20/2016] [Indexed: 06/06/2023]
Abstract
OBJECTIVE To evaluate the effect of creating an air-tight anastomosis and intraoperative dilatation of the hepaticojejunostomy (HJ) in reducing the early and long-term complications. STUDY DESIGN Interventional study. PLACE AND DURATION OF STUDY Department of Surgery, King Saud University, Riyadh, between March 2008 and January 2016. METHODOLOGY After completion of HJ, the anastomosis was tested for air-tightness, and dilated with Kelly clamp in all patients undergoing the procedure. The anastomosis was reinforced with extra suture in cases of air leak. Comparison was performed between the patients who underwent HJ by the same surgeon, after and before the new technique. RESULTS Sixty-seven patients underwent HJ during the study period. Air leaks from HJ were observed in 3 patients before anastomotic dilatation. The anastomosis was reinforced in these patients. No air leak was observed after dilatation of the anastomosis. There was no postoperative bile leak in any patient. However, during the follow-up 3 patients presented with recurrent cholangitis and stricture formation at the HJ site required surgical revision. The new technique had significantly reduced the rate of bile leak (p=0.029) and stricture (p=0.037) at the site of HJ when compared with patients who underwent HJ without the new technique. CONCLUSION Creation of air-tight HJ anastomosis has completely eliminated the postoperative bile leak and reduced the rate of HJ stricture formation. The addition technique resulted in insignificant prolongation of operative time. There was no technique related complication.
