Background and study aims Management of post-sleeve gastrectomy fistulas (PSGF) recently has evolved, resulting in prioritization of internal endoscopic drainage (IED). We report our experience with the technique in a tertiary center. Patients and methods This was a single-center, retrospective study of 44 patients whose PSGF was managed with IED, comparing two periods: after 2013 (Group 1; n = 22) when IED was used in first line and before 2013 (Group 2; n = 22) when IED was applied in second line. Demographic data, pre-endoscopic management, characteristics of fistulas, therapeutic modalities and outcomes were recorded and compared between the two groups. The primary endpoint was IED efficacy; the secondary endpoint was a comparison of outcomes depending on the timing of IED in the management strategy. Results The groups were matched in gender (16 female, 16 male), mean age (43 years old), severity of fistula, delay before treatment, and exposure to previous endoscopic or surgical treatments. The overall efficacy rate was 84 % (37/44): 86 % in Group 1 and 82 % in Group 2 (NS). There was one death and one patient who underwent surgery. The median time to healing was 226 ± 750 days (Group 1) vs. 305 ± 300 days (Group 2) (NS), with a median number of endoscopies of 3 ± 6 vs. 4.5 ± 2.4 (NS). There were no differences in number of nasocavity drains and double pigtail stents (DPS), but significantly more metallic stents, complications, and secondary strictures were seen in Group 2. Conclusion IED for management of PSGF is effective in more than 80 % of cases whenever it is used during the therapeutic strategy. This approach should be favored when possible.

Background Staple-line leak following laparoscopic sleeve gastrectomy is a dire adverse event. While the treatment of acute and early leaks is well established, there is still dispute regarding late and chronic leaks. We describe an endoscopic approach combining septotomy and sleeve stricture dilation for treating late/chronic leaks. Methods Ten consecutive patients with late/chronic proximal leaks were treated at our center. The septum separating the sleeve lumen from the perigastric cavity was...

Abstract Background Sleeve gastrectomy has become a popular weight loss procedure, but it is associated with staple line leak resulting in high morbidity and mortality. Current management options range from endoscopic techniques (predominantly stent placement) to surgical intervention. Objective The purpose of this study was to recognize endoluminal vacuum (E-Vac) therapy as a viable option for use in anastomotic leaks of sleeve gastrectomies. Setting This study took place at Baylor University M...

Background and study aims: Diverse endoscopic methods, such as placement of temporary self-expandable stents, have proven effective for the treatment of post-bariatric surgery leaks. However, some patients do not respond to the usual endoscopic treatment. This study tested the efficacy of an alternative treatment strategy based on trans-fistulary drainage with double-pigtail plastic stents. Patients and methods: We performed a retrospective analysis of patients with abdominal collections followi...

Introduction Upper intestinal leaks and perforations are associated with high morbidity and mortality rates. Despite the growing experience using endoscopically placed stents, the treatment of these leaks and perforations remain a challenge. Endoluminal vacuum (E-Vac) therapy is a novel treatment that has been successfully used in Germany to treat upper gastrointestinal leaks and perforations. There currently are no reports on its use in the USA.

Introduction The management of post-operative anastomotic leakage and fistulas of the upper GI tract remains challenging. Fully covered stents are used despite a high risk of migration because of a better removability. The goal of our study was to evaluate the effectiveness of this new type of endoscopic stent in this indication. The secondary objective was to determine the ability of withdrawing this stent.

Background Leaks are considered one of the major complications of laparoscopic sleeve gastrectomy (LSG) with a reported rate up to 7 %. Drainage of the collection coupled with SEMS deployment is the most frequent treatment. Its success is variable and burdened by high morbidity and not irrelevant mortality. The aim of this paper is to suggest and establish a new approach by endoscopic internal drainage (EID) for the management of leaks.

Sleeve gastrectomy is currently the most frequently performed bariatric surgery. Postoperative leaks represent the main cause of morbidity in up to 8% of patients with a mortality rate ranging between 0.1 and 5%. However, management of these leaks remains controversial. We report the case of a patient presenting with sepsis 2 weeks after surgery. A subphrenic collection and a leak were found on CT. Despite medical treatment, the patient did not show clinical improvement. Hence, we considered a t...

Endoscopic suturing allows for select patients with perforations, leaks, and fistulas to be managed endoscopically. Experience with the Overstitch endoscopic suturing device suggests it may be superior to endoclips in the management of perforations, because of its ability to achieve full-thickness suturing and create an airtight closure. Although successful closure of leaks and fistulas using the Overstitch device has been described, additional therapy with a multimodality approach is often requ...

Abstract Background The management of laparoscopic sleeve gastrectomy leaks remains a challenge. This can be treated with placement of self-expandable metal stents, which are most effective in the acute and early settings. However, migration is a frequent adverse event (AE). Novel, fully covered stents with a larger proximal flare to limit migration designed specifically to treat postsleeve leaks were recently introduced.
