Background: Duodenal stump fistula represents an infrequent but serious complication after laparoscopic radical gastrectomy with Billroth II or Roux-en-Y reconstruction for gastric cancer. The present study was designed to evaluate the effectiveness of laparoscopic double half purse-string sutures plus "8" pattern of stitching for reinforcement of duodenal stump. Methods: The data of patients undergoing laparoscopic radical gastrectomy with Billroth II or Roux-en-Y reconstruction were retrospectively analyzed between August 2022 and June 2023. According to the different reinforcement methods of duodenal stump, included patients were subdivided into three groups as follows: Group A, duodenal stump was treated with double half purse-string sutures plus "8" pattern of stitching; Group B, duodenal stump was reinforced by continuous suture using a barbed suture; and Group C, duodenal stump without any additional processing. The incidences of duodenal stump fistula between three groups were documented and compared. Moreover, the independent risk factors associated with duodenal stump fistula were analyzed using the logistic regression analysis. Results: No postoperative duodenal stump fistula occurred in Group A, which was significantly different from Group B and Group C ( P = .007). In the multivariate analysis, age (odds ratio [OR], 1.191; 95% confidence interval [CI], 1.088-1.303), body mass index (OR, 0.824; 95% CI, 0.727-0.935), and American Society of Anesthesiologists score (OR, 4.495; 95% CI, 1.264-15.992) were the risk factors for duodenal stump fistula. Conclusion: Double half purse-string sutures plus "8" pattern of suture can be conducted in a relatively short operation period and could prevent the incidence of duodenal stump fistula to some extent.

Anorectal malformation includes various types of anomalies. The goal of definitive surgery is achievement of fecal continence. Twenty years have passed since laparoscopically assisted anorectoplasty (LAARP) was reported by Georgeson. Since LAARP is gaining popularity, its long-term outcomes should be evaluated. Presently, there is no evidence regarding the optimal method of ligating and dividing the fistula correctly and creating the pull-through canal accurately. Rectal prolapse and remnant of the original fistula (ROOF) tend to develop more often in LAARP patients than in posterior sagittal anorectoplasty (PSARP) patients; however, robust evidence is not available. Prolapse may be prevented by suture fixation of the rectum to the presacral fascia; however, if prolapse occurs, the indication, timing, and the best method for surgical correction remain unclear. Most patients with ROOF are asymptomatic, and there is controversy regarding the indications for ROOF resection. This article aimed to detail the various modifications of the LAARP procedures reported previously and to describe the surgical outcomes, particularly focusing on rectal prolapse, ROOF, and fecal continence, by reviewing the literature. Functional outcomes after LAARP were almost similar to those noted after PSARP, and we have demonstrated that LAARP is not inferior to PSARP with respect to fecal continence. Although there is controversy regarding the application of LAARP for recto-bulbar cases, we believe that LAARP is still evolving, and we can achieve better outcomes by improving the procedure., (© 2020 Asia Endosurgery Task Force and Japan Society of Endoscopic Surgery and John Wiley & Sons Australia, Ltd.)

Objective: To evaluate the influence of a visceral protective layer (VPL) on the formation of enteroatmospheric fistulae (EAF) in open abdomen treatment (OAT) for peritonitis., Background: EAF formation is a severe complication of OAT. Despite the widespread use of OAT, there are no robust evidence-based recommendations for preventing EAF., Methods: A total of 120 peritonitis patients with secondary peritonitis as a result of a perforation of a hollow viscus or anastomotic insufficiency who had undergone OAT were included, and 14 clinical parameters were recorded in prospective OAT databases at 2 tertiary referral centers. For this analysis, patients with a VPL were assigned to the treatment group and those without a VPL to the control group. Propensity Score (PS) matching was performed. Known risk factors in OAT such as malignant disease, mortality, emergency operation, OAT duration, and fascial closure were matching variables. The influence of VPL on EAF formation was statistically evaluated using logistic regression analysis., Results: With 34 patients in each group, no notable differences were identified with regard to age, sex, underlying disease, mortality, emergency operation, fascial closure, and OAT duration. Overall, a mortality rate of 22.1% for OAT due to peritonitis was observed. Mean OAT duration was approximately 9 days, and secondary fascial closure was achieved in more than two-thirds of all patients. Fascial traction was used in more than 75% of cases. EAF formation was significantly more frequent in the control group (EAF formation: VPL group 2.9% vs control 26.5%; P = 0.00). In the final regression analysis, the use of VPL resulted in a significant reduction in the risk of EAF formation (odds ratio 0.08; 95% confidence interval 0.01-0.71, P = 0.02), which translates to a relative risk reduction of 89.1%., Conclusion: VPL effectively prevents EAF formation during OAT in patients with peritonitis. We recommend the consistent use of VPL as part of a standardized OAT treatment algorithm., Competing Interests: All authors declare there is no conflict of interest., (Copyright © 2019 Wolters Kluwer Health, Inc.

Objective . A Perioperative Safety Checklist (PSC) for gastric cancer (GC) was established to evaluate the effects of PSC on the clinical outcomes of GC. Methods . This single-center preliminary observational study conducted at a tertiary referral hospital included patients with GC who underwent surgery from January 1, 2016, to June 30, 2016, treated without PSC (allocated to the control group) and those who underwent surgery between January 1, 2017, and June 30, 2017, managed according to the PSC designated as the PSCGC (Perioperative Safety Checklist for Gastric Cancer) group. Results . Overall, 1072 cases were enrolled, 556 cases in PSCGC group and 526 cases in control group. After matching, there were 474 patients in each group. PSC intervention led to significant reductions of the incidence of postoperative intestinal fistula formation ( P = .034), the incidence of unplanned secondary surgery ( P = 0.039), and the total hospitalization expenses ( P < .001). Total completion rate of all 14 checklists items was 79.1%. Intraoperative blood loss in the complete and partial implementation groups was significantly lower than the complete nonimplementation group ( P = .002), whereas hospitalization cost showed an opposite trend, which was significantly higher in the incomplete nonimplementation group ( P = .015). Conclusion . PSC implementation was associated with a decreased incidence of gastrointestinal fistula formation, unplanned secondary surgery, and hospitalization cost in patients with GC. However, it had no effect on the in-hospital mortality, the incidence of postoperative complications during hospitalization (ie, incision complications and lung infections), unplanned secondary admission, and the duration of postoperative hospital stay.

Background: A mesh-related intestinal fistula is an uncommon and challenging complication of ventral hernia repair. Optimal management is unclear owing to lack of prospective or long-term data., Methods: We reviewed our prospective data for mesh-related intestinal fistulas from 2004 to 2017and compared suture repair versus ventral hernia repair with mesh at the time of mesh-related intestinal fistula takedown., Results: Eighty-two mesh-related intestinal fistulas were treated; none of the fistulas had closed spontaneously, and all fistula persisted at the time of our treatment. Mean age was 61 ± 12 years with 33-month follow-up. Comorbidities were similar between groups. Defects were 2.5-times larger in ventral hernia repair with mesh (324 ± 392 cm 2 vs 1301 ± 133 cm 2 ; P = .044). Components separation (64% vs 21%; P = .0003) and panniculectomy (35% vs 7%; P = .0074) were more common in ventral hernia repair with mesh. Mortality occurred in 4 patients. Complications were similar. In patients undergoing ventral hernia repair with non-bridged, acellular, porcine dermal matrix, hernia recurrence was less than in patients without mesh (26% vs 66%; P = .0030). Only partial excision of the mesh involved with the fistula resulted in a substantial increase in developing another fistula (29% vs 6%; P < .05)., Conclusion: Patients undergoing preperitoneal ventral hernia repair with mesh for mesh-related intestinal fistula had a lesser rate of hernia recurrence and similar complications compared to suture repair despite larger hernias. Complete mesh excision decreases the risk of fistula recurrence. We maintain that ventral hernia repair with mesh during mesh-related intestinal fistula takedown represents the best opportunity for a durable herniorrhaphy., (Copyright © 2019 Elsevier Inc.

Treatment of an open abdomen (OA) wound combined with an intestinal fistula is a challenge in the clinic. Here, inspired by the antibacterial activity of graphene (G) and its derivatives, we present a hybrid patch based on the ability of graphene and polycaprolactone (PCL) to kill bacteria and save the cells in a wound. Benefiting from the antibacterial ability of graphene oxide (GO), cells could survive in the presence of bacteria. With the increased ability to protect cells, this patch accelerated wound healing in an OA and intestinal fistula wound model. Additionally, the sub-acute toxicity score showed no extra damage to organs. In conclusion, the employment of the hybrid material for an OA and an intestinal fistula wound healing is encouraging. A hybrid patch based on graphene oxide and polycaprolactone electrospun was generated for open abdomen and fistula wound. The application of the hybrid patch could save the cells from bacteria which contribute to accelerating wound healing.

Background: Duodenal stump fistula (DSF) after gastrectomy is of low frequency but a critical complication in gastric cancer surgery. Manual oversewing for reinforcement of the duodenal stump is not applicable when free longitudinal margin is short and has technical difficulties in laparoscopic surgery. This trial evaluated the safety and feasibility of using a linear stapler with bioabsorbable polyglycolic acid (PGA) sheet for duodenal stump closure and reinforcement in gastric cancer surgery., Methods: This multi-institutional, prospective phase II trial included gastric cancer patients who were scheduled to undergo distal or total gastrectomy with R-Y reconstruction. In all cases, duodenum was transected using a linear stapler with PGA sheet. The primary endpoint was the incidence of postoperative DSF. Sample size was set at 100 patients considering an expected value of 3% and threshold value of 8% with one-sided testing at a 10% significance level., Results: Between June 2014 and June 2015, a total of 100 patients were registered in this trial. Postoperative DSF was observed in two cases (2.0%, 90% CI 0.4-6.2%) which was developed on postoperative days 13 and 20. Intraoperative bleeding at the duodenal stump staple line was observed in one case but was easily controlled without additional suturing. Postoperative bleeding was not observed in any of the cases., Conclusion: This study suggested that the use of PGA sheet as a reinforcement material for closure of the duodenal stump during gastrectomy for gastric cancer is both safe and feasible. Trial registration number UMIN 000014398.

There are very few clinical studies that highlight a definitive and comprehensive guideline for the management of enterocutaneous fistulas. Most accepted guidelines are found in textbooks and are taken from expert advice and case reports. The goal of this review is to highlight advancements relevant to the management of enterocutaneous fistulas from the recent two to three years. Although strong evidence-based guidelines are lacking, the consensus is that a multidisciplinary team working with a clear treatment plan targeting multiple aspects of management can maximize patient outcomes.

Intestinal fistula, as a serious complication after abdominal surgery, not only leads to a series of pathophysiological changes such as fluid loss, malnutrition and organ dysfunction, but also causes the severe abdominal infection, which often threatens the life of patients. How to make the diagnosis and give the treatment of intestinal fistula is the key to save the lives of high-risk patients. In our hospital, during the past course of diagnosis and treatment for intestinal fistula complicated with severe abdominal infection, based on the combination of literatures at home and abroad with our clinical experiences for many years, an effective three-stage prevention and treatment strategy was formed gradually, which included early diagnosis, effective treatment of infection source, open drainage of abdominal infection and early enteral nutrition support. This strategy subverts the traditional concept of surgery alone, and becomes an effective means to save patients with severe abdominal infection.

Duodenal injury is a serious abdominal organ injury. Duodenal fistula is one of the most serious complications in gastrointestinal surgery, which is concerned for its critical status, difficulty in treatment and high mortality. Thoracic and abdominal compound closed injury and a small part of open injury are common causes of duodenal injury. Iatrogenic or traumatic injury, malnutrition, cancer, tuberculosis, Crohn's disease etc. are common causes of duodenal fistula, however, there has been still lacking of ideal diagnosis and treatment by now. The primary treatment strategy of duodenal fistula is to determine the cause of disease and its key point is prevention, including perioperative parenteral and enteral nutrition support, improvement of hypoproteinemia actively, avoidance of stump ischemia by excessive separate duodenum intraoperatively, performance of appropriate duodenum stump suture to ensure the stump blood supply, and avoidance of postoperative input loop obstruction, postoperative stump bleeding or hematoma etc. Once duodenal fistula occurs, a simple and reasonable operation can be selected and performed after fluid prohibition, parenteral and enteral nutrition, acid suppression, enzyme inhibition, anti-infective treatment and maintaining water salt electrolyte and acid-base balance. Double tube method, duodenal decompression and peritoneal drainage can reduce duodenal fistula-related complications, and then reduce the mortality, which can save the lives of patients.

Introduction: The risk of digestive fistula in patients operated for gastric neoplasm is increased due to biological imbalances generated by the cancer's progression, by diagnosis in advanced stages, and by the scale of intervention. Under these circumstances the use of some technical means to protect digestive sutures in these patients is useful., Aim: To analyse the efficiency of technical means to protect the digestive sutures in patients operated in various stages of development of gastric cancer. Material and Methods: We conducted a retrospective study on a group of 130 patients operated for gastric cancer in the 1st General Surgery and Oncology Clinic of the Bucharest Institute of Oncology, between 2010-2014. Results: 38.46% of the patients in the study group presented stage IV cancer with multiple complications and biological imbalances. 52 total gastrectomies and 40 gastric resections were carried out, while in 34 patients palliative "tumour excisions" or other types of palliative surgery were performed. In 15 of the cases with gastric resection a duodenal decompression probe was used, while in 13 of the patients with total gastrectomy an oeso-jejunal aspiration probe together with an oeso-jejunal feeding probe were used as additional technical measures to prevent fistula formation. The incidence of duodenal stump fistula was 7.69%, that of oeso-jejunal anastomosis fistula was 2.3%, with an overall mortality of 3.07% and that of gastro-jejunal anastomosis fistula was 0.76%., Conclusion: Given the risk of fistula development in patients with gastric cancer, as well as the increased risk in advanced stages of cancer development, we consider that the use of technical means of protection of digestive sutures is beneficial and opportune, lowering the incidence of fistulas, reducing their output, pathophysiological effects, and mortality., (Celsius.)

Purpose: The aim of this study was to evaluate the efficacy of vacuum-assisted closure therapy in patients with open abdomen due to secondary peritonitis and to identify possible risk factors of fistula formation., Methods: The hospital OPS-database (time period 2005-2014) was searched to identify patients treated with an open abdomen due to secondary peritonitis, who underwent vacuum-assisted closure therapy. Medical records were retrospectively analyzed for patients' characteristics, cause of peritonitis, duration of vacuum therapy, number of relaparotomies, fascial closure rates, and risk factors of fistula formation., Results: Forty-three patients (19 male, 24 female) with a median age of 65 years (range 24-90 years) were identified. The major cause of secondary peritonitis was anastomotic leakage after intestinal anastomosis or bowel perforation, the median APACHE II score was 11. Median duration of VAC treatment was 12 days (range 3-88 days). Twenty of 43 (47 %) patients died from septic complications. Delayed fascial closure was obtained by suturing in 20 of 43 patients (47 %). Overall 16 of 43 (37 %) patients developed enteroatmospheric fistulas. Re-explorations after starting VAC treatment and duration of VAC therapy were significantly associated with the occurrence of enteroatmospheric fistulas (p < 0.001). ROC curve analysis determined the optimal duration of VAC therapy to reduce the risk of fistula formation at 13 days., Conclusions: Long-term VAC treatment of patients with an open abdomen due to secondary peritonitis results in a relatively low fascial closure rate and a high risk of fistula formation.

Background: Entero-atmospheric fistula (EAF) is an enteric fistula occurring in the setting of an open abdomen, thus creating a communication between the GI tract and the external atmosphere. Management and nursing of patients suffering EAF carries several challenges, and prevention of EAF should be the first and best treatment option., Purpose: Here, we present a novel modified classification of EAF and review the current state of the art in its prevention and management including nutritional issues and feeding strategies. We also provide an overview on surgical management principles, highlighting several surgical techniques for dealing with EAF that have been reported in the literature throughout the years., Conclusions: The treatment strategy for EAF should be multidisciplinary and multifaceted. Surgical treatment is most often multistep and should be tailored to the single patient, based on the type and characteristics of the EAF, following its correct identification and classification. The specific experience of surgeons and nursing staff in the management of EAF could be enhanced, applying distinct simulation-based ex vivo training models.

Inflammatory bowel disease patients will likely come to the surgeon's attention at some point in their course of disease, and they present several unique anatomic, metabolic, and physiologic challenges. Specific and well-recognized complications of chronic Crohn disease and ulcerative colitis are presented as well as an organized and evidence-based approach to the medical and surgical management of such disease sequelae. Topics addressed in this article include intestinal fistula and short bowel syndrome, pouch complications, and deep venous thrombosis with emphasis placed on optimization of the patient's physiologic state for best outcomes., (Published by Elsevier Inc.)

Diverticular disease represents the most common disease affecting the colon in the Western world. Most cases remain asymptomatic, but some others will have symptoms or develop complications. The aims of treatment in symptomatic uncomplicated diverticular disease are to prevent complications and reduce the frequency and intensity of symptoms. Fibre, probiotics, mesalazine, rifaximin and their combinations seem to be usually an effective therapy. In the uncomplicated diverticulitis, outpatient management is considered the optimal approach in the majority of patients, and oral antibiotics remain the mainstay of treatment. Admission to hospital and intravenous antibiotic are recommended only when the patient is unable to intake food orally, affected by severe comorbidity or does not improve. However, inpatient management and intravenous antibiotics are necessary in complicated diverticulitis. The role of surgery is also changing. Most diverticulitis-associated abscesses can be treated with antibiotics and/or percutaneous drainage and emergency surgery is considered only in patients with acute peritonitis. Finally, patient related factors, and not the number of recurrences, play the most important role in selecting recipients of elective surgery to avoid recurrences., (Copyright © 2015 Elsevier España, S.L.U. and AEEH y AEG.

Double pylorus (DP), is a form of gastroduodenal fistula, which consists of a short accessory canal from the gastic antrum to the duodenal bulb, and mostly occrus in the background of peptic ulcer disease. Prevalence, as well long-term follow-up of patients with DP is less elucidated in western countries. Aim of our study was to analyse demografic, clinical and endoscopic characteristics in our case-series. During 2008-2013. a total of 23836 upper endoscopies were performed in 16759 patients. DP was diagnosed in 6 patients (prevalence of 0.04%). The follow-up period was f 8 to 72 months. In 87% DP was a complication of the upper gastrointestinal bleeding. In 83% cases opening of the fistula was on lesser curvature of gastric antrumu. During follow-up period the fistula healing did not occur in any of our patients. DP is a very rare entity, with a benign course of the disease Associated comorbidity and use of ulceriform medications plays important role in persistence of DP, wheras possible eradication of Helicobacter infection in this background remains elusive.

Background: Despite advances in medical therapies, many children with Crohn's disease (CD) will require bowel resection. Although previous registry studies have attempted to identify risk factors for surgery, the effect of immunomodulators and biologics (IMB) on surgical indications has not been well characterized., Methods: We reviewed a series of 125 children with CD who underwent bowel resection with reanastomosis between 1977 and 2011 and were followed up for at least 6 months. We compared patients who underwent surgery for perforating disease (abscess or internal fistula) and patients who were operated on for medically refractory or fibrostenosing disease. Between these 2 groups, we examined medications received before surgery. Other demographic and disease-specific covariates were examined., Results: Of the 82 patients who received IMB before surgery, only 19 patients (23%) required surgery for a perforating complication of CD, whereas 63 patients (77%) required surgery for strictures or medically refractory disease. In contrast, of the 43 patients who did not receive IMB preoperatively, 20 patients (45%) developed a perforating complication and 23 patients (53%) required surgery for strictures or refractory disease. These differences across groups were significant, with a lower rate of operation for perforating disease among patients receiving preoperative IMB therapy (P = 0.007)., Conclusions: In our surgical cohort, children with CD who were treated with IMB were less likely to have surgery for perforating disease. This finding raises the possibility that the administration of IMB in children who require surgery may be associated with a difference in disease behavior.

Background: Negative pressure wound therapy (NPWT) is an established and effective tool in the management of complicated abdominal wounds. This management approach has been used in infants, but few large series reports exist in the literature., Methods: The outcomes of infants with abdominal wounds receiving NPWT over the last 10 years at our institution were evaluated. Overall survival, time between initiation of NPWT, and discharge/death were examined., Results: We identified 18 infants who had abdominal wounds treated with NPWT. Diagnoses were varied, as was the duration of therapy. The median NPWT duration of treatment was 34.0 ± 92.1 days. Forty-four percent of the infants had a stoma before application of NPWT, and 22% of the infants had enterocutaneous fistulas before use of NPWT. There were only 2 cases in which a new fistula developed during the use of NPWT, and both of these omphalopagus conjoined twins had undergone the Bianchi procedure. No additional NPWT-related complications were identified. Of 18 infants, 6 died in this cohort., Conclusion: Negative pressure wound therapy is an important therapeutic tool for the management of abdominal wounds in infants., (Copyright © 2012 Elsevier Inc.

Introduction: Among the different factors described, nutritional support has been associated to prevention and management of enterocutaneous fistulae (ECF)., Objectives: To assess the influence that the parameters related to nutritional, clinical status, and surgical variables have on the occurrence of ECF., Methods: An observational case/control retrospective study was performed on patients admitted to the General and Digestive Surgery Department. The parameters analyzed were: diagnosis, body mass index (BMI), pathologic personal history, number of surgical interventions (SI) and complications (previous infection, bleeding, and ischemia). In patients with SI, we analyzed: number and type of SI, time until onset of nutritional support, and type of nutritional support. We performed a multiple logistic uni- and multivariate regression analysis by using the SPSSv.19.0 software., Results: The primary diagnoses related to the occurrence of ECF were pancreatic pathology (OR = 5.346) and inflammatory bowel disease (IBD) (OR = 9.329). The surgical variables associated to higher prevalence of ECF emergency SI (OR = 5.79) and multiple SI (OR = 4.52). Regarding the nutritional variables, the late onset of nutrition (more than three days after SI) was associated to the occurrence of ECF (OR = 3.82)., Conclusions: In surgical patients, early nutritional support , independently of the route of administration, decreases the occurrence of fistulae. Pancreatic pathology, IBD, emergency SI, and multiple SI were associated to higher prevalence of ECF. The variable hyponutrition appears as a risk factor that should be confirmed in further studies.

Background: The open abdomen (OA) is a severe disease pattern accompanied by high morbidity and mortality. It is either result of a surgical dis-ease or approach. The aim of this review article is to provide a systematic overview on the options of a temporary closure of the abdominal wall including early and late consequences in the treatment of an open abdomen based on the current medical literature., Methods: Topic-related, selective, PubMed-based literature search of the last decade including historically relevant references combined with own clinical experiences., Results: The initial course is marked by problems in intensive care. The most frequent causes of -death are ventilatory problems, acute renal fail-ure, persisting infections and sepsis as well as multiorgan failure. Intensive care duration ranges from 13 to 65 days. Perioperative mortality is account-ed for 10-52 %. Specific complications can be seen in surviving patients such as enteroatmospheric fistula (1.3-41 %), ventral hernia (32-100 %), intraabdominal abscess formation (2.1-21 %), intestinal adhesions and digestion disturbances, neurological und psychological problems (approximately 20 %) as well as heterotopic ossification (17-25 %)., Discussion: Application of a temporary abdominal closure aims to avoid those complications. Furthermore, time and effort for care and treatment are recommended to be reduced as patients comfort should be improved, simultaneously. Primary fascial closure is of utmost importance to reach this goal. Procedures with highest fascial closure rate (Wittmann patch, STAR, 75-93 %; dynamic retention sutures, 61-91 %; V.A.C., 69-84 %) have lowest mortality., Conclusion: Type and severity of the various early and late consequences in the treatment of an open abdomen are substantially determined by the complication-inducing causes and the basic disease as well as by the options of an efficient, even in some cases temporary closure of the abdominal wall., (© Georg Thieme Verlag KG Stuttgart ˙ New York.)

Background: The risk of fistula formation is a major concern after incision and drainage of an anorectal abscess., Objective: Our objective was to the test the effects of antibiotic treatment on fistula formation after incision and drainage of anorectal abscesses., Design: Randomized, placebo-controlled, double-blind study., Setting: Multicenter trial at 3 teaching hospitals in Turkey., Patients: Patients who underwent abscess drainage between September 2005 and January 2008 were evaluated for eligibility. Exclusion criteria included penicillin allergy, antimicrobial agent usage before enrolment, other infection, previous anorectal surgery, inflammatory bowel disease, suspicion of Fournier gangrene, secondary and recurrent anorectal abscesses, anal fistula at time of the surgery, immune compromised states, and pregnancy., Intervention: Patients were randomly assigned to receive placebo or amoxicillin-clavulanic acid combination treatment for 10 days after abscess drainage., Main Outcome Measures: The primary end point was rate of anorectal fistula formation at 1-year follow-up., Results: : Of 334 patients assessed for eligibility, 183 entered the study (placebo, 92; antibiotics, 91). Data were available for per-protocol analysis from 151 patients (placebo, 76; antibiotics, 75) with a mean age of 37.6 years; 118 patients (78.1%) were men. Overall, 45 patients (29.8%) developed anal fistulas during 1-year follow-up. Fistula formation occurred in 17 patients (22.4%) in the placebo group and in 28 patients (37.3%) in the antibiotic group (P = .044). Risk of fistula formation was increased in patients with ischiorectal abscess (odds ratio, 7.82) or intersphincteric abscess (odds ratio, 3.35) compared with perianal abscess., Conclusion: Antibiotic treatment following the drainage of an anorectal abscess has no protective effect regarding risk of fistula formation.

Purpose: Gastrostomy is a commonly undertaken procedure in children. Methods for gastrostomy insertion have evolved and laparoscopy is commonly used to aid its insertion. The aim of this study is to review the outcome and complications of laparoscopic-assisted gastrostomy insertion., Methods: A retrospective case note review of children undergoing gastrostomy insertion by a single surgeon from 1999 to 2007., Results: 114 children underwent gastrostomy insertion, 68 males and 46 females, with a median age of 55 months (IQR 28-149 months). The majority were neurologically impaired. 98 underwent laparoscopic-assisted PEG (86%), 1 was converted to open procedure (0.9%) and 16 had standard PEG (14%). Median follow-up was 10.5 months with 90 children having their original gastrostomy changed to a button at a median interval of 7.4 months. Complications observed included new or deteriorating gastro-oesophageal reflux (GOR) (n = 16), infection (n = 9), granulation tissue (n = 11), tube dislodgement (n = 2) and intra-abdominal leakage of feed (n = 2). There were two gastrocolic fistulae which occurred in the standard PEG group., Conclusion: The inadvertent formation of a gastrocolic fistula was avoided with the use of laparoscopy to aid PEG insertion.

A contained open abdomen is commonly used during damage control laparotomy and consists of the temporary coverage of the abdomen for protection of the viscera and reduction of intra-abdominal pressure. Definitive closure of a contained open abdomen is technically difficult due to the inability to obtain primary fascial suture. The insertion of a prosthetic mesh can be complicated with enterocutaneous fistula, and other definitive closure techniques need several surgical procedures. We describe a low cost technique that allows definitive closure of large abdominal wall defects avoiding the risk of intestinal fistula., ((c) 2008 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Context: Pseudoaneurysm of the hepatic artery after a pancreaticoduodenectomy is a serious complication, which should always be considered in the differential diagnosis when late bleeding has occurred., Case Report: We report a case of pseudoaneurysmal rupture of the common hepatic artery into the biliodigestive anastomosis. A 55 year old female patient with a history of pancreatic head cancer underwent a pylorus preserving pancreaticoduodenectomy at our hospital in September 2008. Six days postoperatively the patient underwent surgery because of sentinel bleeding of a portal vein branch. On the 40th postoperative day she presented melena. Upper gastrointestinal endoscopy indicated bleeding near the biliodigestive anastomosis. An emergency angiography demonstrated a pseudoaneurysm of the common hepatic artery. Transcatheter arterial embolization was performed and a hemodynamic stabilization of the patient was achieved. Six days after the embolization the patient developed hemorrhagic shock and an urgent relaparotomy was carried out. The explorative laparotomy revealed bleeding of the common hepatic artery into the biliodigestive anastomosis in the form of an arteriointestinal fistula. The anastomosis was opened, the ruptured pseudoaneurysm was sutured, and a new biliodigestive anastomosis was made. The patient has been well for two months with good liver function, without rebleeding., Conclusion: This case illustrates the occurrence of a rare complication (rupture of a hepatic artery pseudoaneurysm) inside the biliodigestive anastomosis after pancreaticoduodenectomy, appearing as upper gastrointestinal bleeding. Different modalities such as transarterial embolization and the use of stents give promising results, but ligation of the pseudoaneurysm and repair of the intestinal communication is also an effective modality of treatment.

Enteric fluids produced by enterocutaneous fistulae can cause severe inflammation in the surrounding skin. By removing these corrosive fluids, topical negative pressure can help maintain skin integrity and promote spontaneous closure.

Background: We sought to identify causes of preventable complications related to operations for Hirschsprung disease., Methods: We reviewed the cases of 51 patients with Hirschsprung disease who underwent a primary procedure elsewhere, had a complication, and were referred for reoperation., Results: Thirty-five patients had 1 failed operation, 10 had 2, and 6 had 3. Initial operations were Soave (20), Duhamel (15), Swenson (5), transanal endorectal (4), myectomy (3), unknown (3), and laparoscopic Swenson (1). Thirty-one patients presented with a stoma. Patients without a stoma (20) had fecal impaction (8), recurrent enterocolitis (6), and fecal incontinence (6). None had both enterocolitis and incontinence. Reoperation was performed posterior sagittally (40) or transanally (5). Indications included stricture (21), megarectal Duhamel pouches (12), fistulae (11 [8 rectocutaneous, 2 rectourethral, and 1 rectovaginal]), pouchitis (2), and retained aganglionic bowel (8). After reoperation, 14 were continent, 11 had a stoma (8 permanent), 6 had voluntary bowel movements but soiled occasionally, 6 received rectal irrigations to avoid enterocolitis, 6 were incontinent but clean with bowel management, and 2 were lost to follow-up., Conclusion: Stricture, megarectal pouch, fistula, and retained aganglionic bowel are preventable complications. Enterocolitis is partially preventable but can occur after a technically correct procedure. Fecal incontinence is a preventable complication likely because of anal canal damage.

Objectives: We sought to determine whether the performance of pyloric exclusion during repair of penetrating advanced duodenal injuries prevents postoperative duodenal fistulas and improves clinical outcome., Methods: A retrospective chart review of patients from 1995 to 2004 with penetrating duodenal injuries >or=grade II and all combined pancreaticoduodenal injuries was performed. Patients managed either without or with pyloric exclusion were compared on the basis of age, sex, mechanism, injury grade, Injury Severity Score (ISS), hemodynamic stability, the presence of vascular injury or associated injuries, postoperative complications, length of hospital stay, and mortality., Results: Fifteen of 29 patients were managed without pyloric exclusion and 14 with exclusion. Both groups were similar with respect to age, sex, mechanism, injury grade, ISS, hemodynamic stability, the presence of vascular injury, associated abdominal injuries, and mortality rates. A trend toward a higher overall complication rate (71% vs. 33%), pancreatic fistula rate (40% vs. 0%), and length of hospital stay (24.3 days vs. 13.5 days) was evident in the pyloric exclusion group. No duodenal fistula was detected in either patient group., Conclusion: In our study population, the performance of pyloric exclusion for penetrating advanced duodenal injury and combined pancreatic and duodenal injuries did not improve clinical outcome. The trend toward a greater overall complication rate, pancreatic fistula rate, and increased length of hospital stay in the pyloric exclusion group suggests that simple repair without pyloric exclusion is both adequate and safe for most penetrating duodenal injuries.

Over the last 15 years, the contemporary strategies to treat the open abdomen have reduced the lethal complications. Systematic intensive care and modern wound management in conjunction with a plastic barrier to protect the viscera and topical negative pressure on the soft tissues have reduced the development of small bowel fistulas. The literature selected for this review shows that the surgical handling of the exposed bowel, the choice of the material for temporary coverage and early progressive closure of the defect are crucial for the prevention of fistulas. At present, surgeons worldwide have adopted these principles leading to an increase of primary or delayed closure rates. When a small fistula occurs, biological dressings like human acellular dermal matrix and fibrin glue may help to seal the orifice and to treat the patient conservatively. In case of a large fistula, vacuum-assisted wound management is recommended as well. Through a separate hole in the vacuum sponge matching to the fistula, the enteric contents are sucked off while the wound bed heals and is prepared for split thickness skin graft. Surgical resection of established fistula unresponsive to conservative measures should only be performed on patients well-nourished and free of infection with a delay of at least six months. For patients with an open abdomen, surgical expertise and a well-structured management plan offer the best chances to overcome this potentially devastating condition--with or without fistula.

Unlabelled: The most frequent postoperative morbidity and mortality in the colorectal surgery is caused by the failure of the anastomosis. On the base of the statistics the postoperative mortality caused by the failure of the anastomosis can rise up to 20%. In the last decade a lot of types of anastomoses was initiated, for example: telescopic anastomosis, mechanical anastomosis with stapler, anastomosis with a bio-fragmentary ring. In the technique of the telescopic anastomosis, introduced from the beginning of 20th century, many changes had made. The experimental and the operative results shown that the telescopic anastomosis is a secure, fast and cheap procedure in the surgery of the colon., Conclusions: the telescopic anastomosis is applicable also in emergency, with a short septic time , easy procedure and doesn't need special instruments.

There are very few cases in English literature of recurrent postoperative aortic fistulas (RPAFs). These are neo-communications between the aortic bloodstream and the lumen of contiguous organs which occur after unpredictable periods from surgical treatment of a previous fistula. The supradiaphragmatic aorta may fistulize into the airways, pulmonary circulation, oesophagus, and cardiac chambers; the infradiaphragmatic aorta into the intestine, stomach, and vena cava. According to the etiology, aortic fistulas are categorized as postoperative (or secondary) and spontaneous (or primary), and RPAF may be considered a subgroup of secondary fistulas. They may recur even more times in the same patient, hence the role of prevention is of the utmost importance. The simultaneous respect of different surgical principles is crucial to make the risk of recurrence less likely. Surgical treatment represents a real challenge due to the emergency conditions and redo nature of operations. Mortality rate is very high. In this article, we describe a case of recurrent aorto-duodenal communication, we discuss the principles of prevention both for the supra and infradiaphragmatic aorta, we introduce some modifications to the classic categorization and we present the first RPAF literature review.

Purpose: To review our experience of endovascular treatment of aorto-enteric fistula (AEF)., Methods: Between March 1999 and March 2005, 15 patients in five university and teaching hospitals in Belgium and The Netherlands were treated for AEF by endovascular repair. Twelve (80%) were male. The mean age was 67 years. Thirteen (87%) had had previous aortic or iliac surgery, 1.7-307 months before. All patients showed clinical or biochemical signs of bleeding. Eight (53%) were in shock, five (33%) had systemic signs of infection. Eight (53%) patients were treated in an emergency setting. Ten (67%) were treated with an aortouniiliac device, three (20%) with an aortobiiliac device, one with a tube graft and one with occluders only. All patients received antibiotics postoperatively for a prolonged period of time., Results: All AEF were successfully sealed, the 30-days mortality was nil. Mean hospital stay was 20 (2-81) days. One patient died 2.7 months later of postoperative complications, one died of lung cancer. Until now, there are no signs of reinfection in four (27%) patients (mean follow-up 15.7 (1-44) months). However, reinfection or recurrent AEF occurred in nine (60%) patients after 9.5 (0.61-31) months. Seven patients were reoperated successfully, two patients died after reintervention., Conclusion: Endovascular sealing of AEF is a promising technique, which provides time to treat shock, local and systemic infection, and co-morbidity. This creates a better situation to perform open repair in the future with possibly better outcome. Danger of reinfection remains high. Endovascular sealing of AEF should, therefore, be seen as a bridge to open surgery when possible.

Background: Management of intestinal fistulae in open abdominal wounds remains a significant clinical challenge for those caring for patients surviving damage control abdominal operations. Breaking the cycle of tissue inflammation, infection, and sepsis, resulting from leakage of enteric contents, should be a major goal in the approach to these complex patients. We describe a technique utilizing vacuum assisted closure (VAC) which achieves control of enteric flow from fistulae in open abdominal wounds., Methods: The fistula-VAC is fashioned from standard sponge supplies, negative pressure pumps, and ostomy appliances. The fistula-VAC was changed every three days prior to split thickness skin grafting, and every five days following grafting., Results: Five patients underwent application of the fistula-VAC. All patients had complete diversion of enteric contents. This enteric diversion allowed for successful skin grafting in all patients., Conclusion: Application of the fistula-VAC should be considered a useful option in treating patients with intestinal fistulae in open abdominal wounds.

Stoma care nurse specialists are valued for their diverse expertise, but it is essential that all practitioners who regularly care for people with stomas have the opportunity to develop professionally and influence this important area of practice. The vision of a clinical and educational team from Suffolk and south Norfolk led to the development of innovative web-based learning material. The aim is to inspire nurses to engage actively with people who have a stoma. 'Professional care of the person with a stoma' is about caring for the whole person, physically and emotionally, from the period before surgery, to their continuing care in the community. An overview of four aspects of stoma care is presented here as a way of sharing with a wider audience the expert practice harnessed during the development of this web-based module.

Background: Medical management of moderate to severe Crohn's disease (CD) using immunomodulator agents has not eliminated surgical treatment of disease complications. The effect of improved medical treatment on perioperative CD surgical outcome is not known. We analyzed the impact of immunomodulator therapy on the rate of intraabdominal septic complications (IASC) in CD patients undergoing bowel reanastomosis or strictureplasty., Methods: Surgical outcome was reviewed in 100 consecutive CD patients who underwent segmental resection with primary anastomosis or strictureplasty between 1998 and 2002. Multivariate analysis was performed to determine the effect of immunomodulator therapy on rate of IASC (intraabdominal abscess, anastomotic leak, or enterocutaneous fistulae). Immunomodulator agents included azathioprine, 6-MP, methotrexate, and infliximab., Results: IASC developed in 11 of 100 (11%) operations. Immunomodulator use was associated with fewer IASC (4/72 procedures; 5.6%), compared with 7/28 (25%) cases with patients not on therapy (P<.01). IASC were not influenced by steroid use, smoking status, preoperative abscess, or fistula or albumin levels. Immunomodulator use did not affect the length of resection or the rate and number of strictureplasties., Conclusion: Medical management with immunomodulator therapy is safe and significantly decreases postoperative IASC in CD patients undergoing surgical procedures requiring bowel anastomosis or strictureplasty.

In the treatment of gastric cancer total gastrectomy (TG) is one of the most important operation and the esophagojejunal anastomotic leakage is the most important early complication. In our series of 172 consecutive TGs (all controlled with Gastrografin-Rx in fifth postoperative day) we did not have any anastomotic fistula, independently from age, stage, type of limphadenectomy and visceral demolition. We believe that the correct technical performance is the most important factor in the esophagojejunal anastomosis.

Unlabelled: Pre-operative preparation of the colon is carried out with oral and/or intravenous administration of antibiotics and through the mechanical preparation of the colon using various substances to decrease the intraluminal bacterial concentration and remove the larger quantity of fecal material as possible, thus decreasing the risk of anastomosis dehiscence due to an increase in the intraluminal pressure. The role of antibiotics has been completely established while that of mechanical preparation is still questioned. The objective of this study is to assess the actual impact of mechanical preparation on colorectal surgery., Materials and Methods: Forty seven patients who underwent elective colorectal surgery were prospectively evaluated, out of which only 24 had mechanical preparation. We compared variables such as age, sex, preoperative hemoglobin, albumin and leukocyte values, surgery characteristics and type of anastomosis, as well as complications in both groups., Results: We found a higher incidence of fistulas, dehiscences and general complications in the group undergoing mechanical preparation of the colon., Conclusion: The results show that mechanical preparation of the colon does not provide any benefit and may result in a higher incidence of complications in colorectal surgery.

We report a prospective study of 17 cases of enterocutaneous fistulae managed at the University of Benin Teaching Hospital, Benin City, Nigeria between June 1992 and June 1999. All the cases were iatrogenic in origin and all age groups (6 weeks to 68 years, mean 27) were represented. There were 10 males and 7 females. Emergency surgery for acute appendicitis and intestinal obstruction were the commonest causes. Management should be conservative initially but surgery should be resorted to if there is no significant improvement, particularly in circumstances where facilities for total parenteral nutrition are not available. A literature review has been carried out and measures to prevent the development of enterocutaneous fistula are outlined.

The authors share their experiences with treatment of 38 patients with external intestinal fistulas after operations on internal genitals. The patients were divided into three groups: patients with pyo-inflammatory diseases, patients with benign tumors and patients with malignant neoplasms. It is noted that preoperative diagnosis of involvement of the intestine in the process is rather difficult, instrumental methods of examination in patients with pyo-inflammatory diseases are poorly informative. In patients with malignant diseases of the uterus and uterine appendages the sigmoid colon should be examined in order to exclude the penetration of the tumor. Adhesive processes resulting from previous operations are considered to be a predisposing factor. Relaparotomies must be performed with the obligatory participation of the surgeon. Operation on the intestine should be performed before the intervention on the internal genitals. The unloading colostomy must be made in suturing the defect of the colon. The use of the method described allowed to save the life of 36 patients (lethality was 5.3%).
