Chronic fistula in ano associated with adenocarcinoma: a case report with a review of the literature.

The malignant transformation of chronic fistula in ano is rare, accounting for 3% to 11% of all anal canal malignancies. It results from long-standing inflammation and chronic irritation. No guidelines are available for the management of these cases. We herein present a case report of a 55-year-old man who presented with a history of constipation, perianal pain, and discharging fistula in ano of 4-year duration and underwent fistula surgery with recurrence. Biopsy of the fistulous tract revealed adenocarcinoma. He received neoadjuvant chemoradiotherapy, followed by abdominoperineal excision including excision of the fistulous tract. After 18 months of follow-up, he is free of recurrence. We present this case with a review of the literature, highlighting the management strategies.

Total Gastrectomy with Roux-en-Y Limb Reconstruction for Complex and Chronic Fistulas After Laparoscopic Sleeve Gastrectomy: Single-Center Experience.

PURPOSE: When a leak after laparoscopic sleeve gastrectomy (LSG) becomes a chronic fistula, the best surgical treatment remains controversial. The aim of study was to review our experience concerning the treatment of chronic and complex fistulas after LSG. MATERIALS AND METHODS: A retrospective analysis of patients with a gastric fistula following LSG who were treated at our center between January 2013 and December 2018 was performed. All patients included underwent a total gastrectomy with a Roux-en-Y reconstruction (TG) for LSG chronic fistula. RESULTS: During the period considered, 13 patients had a chronic fistula and were treated with open TG. The primary leak evolved to a gastro-cutaneos fistula in three patients (23%), to a gastro-splenic fistula in two patients (15.4%), to a gastro-pleural fistula in four patients (30.8%), and to a gastro-bronchial fistula in four patients (30.8%). During TG, a splenectomy and a spleno-pancreatectomy were needed in the two cases of gastro-splenic fistula. Five patients (38.5%) developed an early complication. Two patients developed an esophago-jejunal anastomotic leak treated with a conservative approach (15.4%). No patients needed hospitalization in the intensive care unit. Overall mean length of stay was 19 days (8-30 days). Mean BMI before LSG was 36 (± 5 kg/m2), mean BMI before TG was 30.3 (± 5.2 kg/m2), and mean BMI 2 years after TG was 23.5 (± 2.9 kg/m2). CONCLUSION: When a more conservative and less mutilating surgical option is not possible, open TG with esophago-jejunostomy remains a valuable salvage procedure in the case of complex and extensive fistulas after LSG.

Chronic aorto-right ventricular fistula following penetrating cardiac injury: A case report.

Aorto-cardiac fistula is a rare but potentially life-threatening condition. We herein report a rare case of chronic aorto-right ventricular fistula formation secondary to a stab penetrating injury to the heart and aorta occurred 15 years ago. The aorto-right ventricular fistula was not found until 15 years after the incident. The fistula had been repaired successfully to prevent further deterioration of cardiac function. Here, we report the clinical presentation, diagnosis and treatment strategies of the aorto-right ventricular fistula, and discuss the possible etiology of the development of the fistula after the penetrating injury.

Fistulojejunostomy for Chronic Fistula After Sleeve Gastrectomy.

The most dreadful complication after sleeve gastrectomy (SG) is staple line leak. Its rate varies between 1 and 2%. With the development of interventional endoscopy, its treatment is currently fairly standardized and allows healing in the majority of cases without revisional surgery. However, if endoscopic treatment fails, surgical treatment becomes unavoidable. Fistulojejunostomy is a surgical option in the management of chronic fistula after SG. Laparoscopic fistulojejunostomy in a patient with chronic fistula after SG is difficult but feasible. This procedure allows complete healing and nutritional recovery in the case of failure of other endoscopic modalities.

Laparoscopic Roux-en-Y Double Fistulo-Jejunostomy for Chronic Gastric Leaks After Converted Vertical Banded Gastroplasty to Sleeve Gastrectomy.

BACKGROUND: As laparoscopic sleeve gastrectomy (LSG) is becoming the most popular bariatric procedure worldwide, treatment options for managing complications, in particular gastric leaks, are also emerging. Staple line leak is a major short-term complication of the procedure. Patients with persistent gastric leaks after failure of endoscopic and radiologic management are candidates for salvage surgery. Laparoscopic Roux-en-Y fistulo-jejunostomy (RYFJ) represents a surgical option to treat persistent gastric leak post-LSG. METHODS: We present the case of a 55-year-old woman undergoing laparoscopic double RYFJ for persistent gastric leaks after complicated bariatric surgery. The patient developed two chronic gastric leaks (gastro-esophageal and cardial localizations) following conversion to sleeve gastrectomy for failed vertical banded gastroplasty. With the two leaks being refractory to endoscopic treatment 6 months later after laparoscopic sleeve gastrectomy, salvage surgery was proposed. Surgery was performed laparoscopically, the gastric leak orifices were identified after careful dissection, and a double RYFJ was successfully completed. RESULTS: Postoperative course was uneventful. The patient remains in good health 6 months after surgery. CONCLUSIONS: Double LRYFJ for chronic leaks after complicated bariatric procedures seems safe with good postoperative outcomes. However, it remains a challenging procedure and should be reserved for selected patients in specialized bariatric centers.

Total Gastrectomy with Roux-En-Y esophagojejunostomy for Chronic Complicated Post-Sleeve Gastric Fistula-Video Report.

INTRODUCTION: Laparoscopic sleeve gastrectomy (LSG) has become one of the most popular bariatric surgeries worldwide. However, complications related to the stapler line can be very serious. Among several challenging post-LSG complications, fistula is the most feared. Its management can be very challenging and chronic. In case of chronic fistula and failure of surgical, endoscopic, and radiological treatment, total gastrectomy with esojejunal anastomosis (RYOJ) can be considered as an effective solution. We describe in this video the steps of our laparoscopic technique. METHODS: We have performed a total gastrectomy with RYOJ in a particular patient with chronic and persisting gastric fistula 9 months after LSG. The body mass index (BMI) was initially 50 kg/m2 at the time of the LSG against 31 kg/m2 on the day of the RYOJ. RESULTS: The postoperative course was uneventful. An upper GI series was done at 1 week and 1 month postoperatively without any abnormality. The patient was evaluated clinically and biologically at 1, 3, and 6 months later on with no evidence of dysphasia or biological abnormality. CONCLUSION: RYOJ in our particular case was efficient. However, longer series and longer follow-up are needed to confirm the effectiveness of this rescue procedure.

Endoscopic Full-Thickness Defects and Closure Techniques.

PURPOSE OF REVIEW: Gastrointestinal transmural defects are defined as total rupture of the gastrointestinal wall and can be divided into three main categories: perforations, leaks, and fistulas. Due to an increase in the number of therapeutic endoscopic procedures including full-thickness resections and the increase incidence of complications related to bariatric surgeries, there has been an increase in the number of transmural defects seen in clinical practice and the number of non-invasive endoscopic treatment procedures used to treat these defects. RECENT FINDINGS: The variety of endoscopic approaches and devices, including closure techniques using clips, endoloop, and endoscopic sutures; covering techniques such as the cardiac septal occluder device, luminal stents, and tissue sealants; and drainage techniques including endoscopic vacuum therapy, pigtail, and septotomy with balloon dilation are transforming endoscopy as the first-line approach for therapy of these conditions. In this review, we describe the various transmural defects and the endoscopic techniques and devices used in their closure.

Proximal Gastrectomy with Double Tract Reconstruction Is an Alternative Revision Surgery for Intractable Complications After Sleeve Gastrectomy.

Gastric leakage and stricture are challenging complications of sleeve gastrectomy (SG). Failure of endoscopic intervention necessitates revision surgery. We describe two cases in which proximal gastrectomy with double tract reconstruction (PG with DTR) was performed in patients with chronic gastric fistula and twisted gastric tube after SG. Following resection of the affected part of the proximal stomach, reconstruction was achieved with three anastomoses [esophagojejunostomy (EJ), gastrojejunostomy (GJ), and jejunojejunostomy]. DTR provides two exit routes, the remnant stomach and the distal jejunum. The GJ was created 15 cm below the EJ with a stoma 10 mm in diameter, which can pass a standard endoscope. Both cases were a success without any short-term complications. PG with DTR could be an alternative option for refractory complications of SG.

Open total gastrectomy with Roux-en-Y reconstruction for a chronic fistula after sleeve gastrectomy.

BACKGROUND: Surgery appears to be the best treatment option for a chronic fistula after laparoscopic sleeve gastrectomy (LSG). Conservative procedures (conversion into a Roux-en-Y gastric bypass, Roux-limb placement) have proven their feasibility and efficacy, but an open total gastrectomy (TG) is sometimes required in challenging situations. OBJECTIVES: To assess outcomes from 12 consecutive patients who underwent surgery for a post-sleeve gastrectomy chronic fistula (PSGCF) between January 2004 and February 2012. SETTING: University public hospital, France. METHODS: Patients with a PSGCF who underwent surgery were included in this retrospective study. Mortality, morbidity (i.e., Clavien-Dindo score), weight loss, and nutritional status were assessed. RESULTS: Twelve of 57 patients (21%) with a post-LSG leak developed a PSGCF. There were 3 men (25%). Mean age was 39±9 years and mean preoperative body mass index was 35±5 kg/m2. All 12 patients underwent an open total gastrectomy with an esojejunostomy (TG). Conservative procedures were considered but not possible. The mean follow-up period was 38±11 months. The mean delay between LSG and TG was 12±6 months. Intraoperative discovery of multiple (>2) gastric fistulas was reported in 9 patients (75%). There were no deaths, but morbidity rate was 50%. Early postoperative fistula occurred in 3 patients (anastomosis n = 1, duodenal stump n = 2). None of these patients required further surgery. The median healing time of the fistula was 37 days (range 24-53). Promising results from weight loss and nutritional status were found at the end of the follow-up. CONCLUSION: A salvage open TG is a well-tolerated and reproducible salvage procedure for cases of a PSGCF, when conservative procedures are not possible.

Curative analysis of local tissue flaps in treatment for huge mobility fistula after breast augmentation / 局解手术学杂志

Objective To investigate the efficacy of breast tissue flap cohesive treatment after breast augmentation injection mixture dis-placed.Methods A total of 78 patients with breast augmentation injection mixture polyacrylamide hydrogel(PAAG)shift in our hospital from January 2006 to March 2014 were divided into two groups according to different surgical methods,39 cases with the material shifted to abdominal wall in control group were treated by taking the cleaning operation to scrape residual cavity,39 patients in observation recieved new breast tissue flap design local treatment of breast fistula closed chest and abdominal wall channel after surgical elimination of the same abdom-inal wall cavities.Results The PAAG extensive deposition in the breast tissue,armpits,chest wall clearance were formed fistula communica-tion.The secretions of patients treated with tissue flap decreased 82%,the lacunar lesions reduced 80% after 2 weeks,while patients without tissue flap,the drain reduced 46%,the lesion size reduced 45%,the difference between the two groups was significant(P <0.01).The heal-ing rate of tissue flap group was higher than that of conventional group after 4 weeks.Conclusion The PAAG mixture shifting formed fistula communication in the abdominal wall is the main reason of the mass flow and a huge cavity.Flap can significantly promote abdominal wall fis-tula healing.

Treatment for displacement of PAAG mixture after injection augmentation mammoplasty.

BACKGROUND: The incidence of serious complications after augmentation mammaplasty with injection of polyacrylamide hydrogel (PAAG) was high. OBJECTIVE: To design a new method for healing of the cavities and cysts after augmentation mammaplasty. METHODS: 102 patients in whom PAAG exceeded the breast and spread to the thoracic-abdominal walls were enrolled and divided into two groups. RESULTS: The flowing masses of different sizes exceeded the breast and spread to the thoracic-abdominal walls, and a large number of PAAG showed flowing degenerative mixture in the tissues and were invaded by many inflammatory cells. PAAG deposited extensively in the breast tissues, armpits and space of the thoracic-abdominal wall, and the breast was connected with the abdominal wall through the fistula of different sizes. At 2 weeks, the percentages of decrease in drainage volume and in lesion lacuna size of the thoracic-abdominal wall (82% and 80%, respectively) in patients receiving the multiple incisions combined with radical therapy were significantly different from those who did not receive the multiple incisions (46% and 45%) (Both P<0.01). At 4 weeks, in some of the patients receiving the multiple incisions combined with radical therapy, the lacuna of the thoracic-abdominal wall disappeared completely, and the lesions with flowing masses had been cleared. CONCLUSIONS: The new method of subareolar incision combined with surgery for inferior segment of mass to clean the mixture and thoroughly eliminate the lacuna of the thoracic-abdominal wall as well as suture to close the intramammary fistula can improve the treatment efficacy.

The Clinical Features and Charateristics of anal Cancer Arising from Chronic Fistula-in-ano

PURPOSE: The incidence of unhealed chronic fistula is about 7% and the cancer can occur in the longstanding unhealed fistula. The most of the cancer is mucinous adenocarcinoma. The report is diverse about treatment, adjuvant chemotherapy and prognosis. The purpose of this study is review of the clinical characteristics and survival of the anal cancer arising from chronic fistula-in-ano. METHODS: The number of patients was 10. The diagnosis is made under pathological examination at the Kanbuk Samsung Hospital from 1983 to 2000. The retrograde study was done with patients' records and telephone questionnaire. The survival rate was calculated with Kaplan-Meier method. RESULTS: All patients were male. The patients had symptoms of anal discharge and anal swelling suggesting the anal fistula. The patients had history of anal surgery. The external openings were multiple. Seven patients had mucinous adenocarcinoma. The prognosis was poor. Among 8 patients' follow-up data, except one patient, 7 patients died within 43 months. CONCLUSIONS: The anal cancer can occur in longstanding unhealed fistula. In our series, all patients were male, and they had multiple opening fistula. The patient who had small size tumor have only survived. Through meticulous exploring and deep biopsy of the fistula, early detection is best method to treat the anal cancer arising from chronic fistula-in-ano.
