Leak or Fistula After Sleeve Gastrectomy: Treatment with Pigtail Drain by the Rendezvous Technique

Insights into the treatment of postsleeve gastrectomy leak: analysis of the results of 105 cases on a national register

BACKGROUND

Many options have been put forward to treat staple line leaks after sleeve gastrectomy (SG) but no clear consensus has emerged concerning a management algorithm.

OBJECTIVES

Aiming to establish a pattern to tailor treatment, the Spanish Society of Obesity Surgery (SECO) and the Obesity Section of the Spanish Association of Surgeons (AEC) set up a national register to record treatment of leaks after SG.

SETTING

Multiple hospital centers, Spain.

METHODS

Between September 2016 and December 2017, cases were entered into an online database. Results were assessed according to the number and type of therapeutic procedures.

RESULTS

One hundred and five patients from 27 centers were diagnosed with postSG leak. The mean age was 44 years, and 77 (73%) were women. Mean body mass index (BMI) was 47 kg/m². Mortality was 7%. The first treatment was effective in 50% of cases with no significant differences between nonoperative management and surgery. We found no significant correlations between appearance of leak, type of treatment (nonoperative management or surgery), and treatment effectiveness. An endoscopic stent was the first nonoperative option in 30% of cases and second option in 50% of cases, with effectiveness of 61% and 50%, respectively. In patients requiring a third treatment option (n = 25), surgery was more effective than nonoperative treatment (75% versus 8%) and the incidence of complications secondary to endoscopic stent placement was high (71%).

CONCLUSION

The choice of postSG leak treatment depends on the patient's clinical condition and the site of the leak. Healing may be slow (>2 months) and may require several interventions using different approaches such as nonoperative treatment, endoscopic stents, or surgery. The effectiveness of endoscopic options decreases and the effectiveness of complex resective or derivative surgery increases with leak duration and the number of treatments required.

Endoscopic titanium clip closure of gastric fistula after splenectomy: A case report

This report describes a 52-year-old male patient with blunt abdominal traumatic rupture of the spleen due to injuries sustained in an automobile accident. Following splenectomy, the patient developed a gastric fistula. He underwent a long period of conservative treatment, including antibiotics and total parenteral nutrition, which was ineffective. The fistula could not be closed and titanium clip closure using a gastroscopy was then performed in order to close the fistula. After endoscopic therapy and clipping surgery, the patient’s general condition improved significantly, and he had no post-procedural abdominal complications. On post-clipping day 6, the gastric fistula was completely closed as shown by X-ray examination of the upper digestive tract. The patient was discharged from hospital and no complications were observed during the six-month follow-up period. Our report suggests that titanium clip closure using endoscopy may be the choice of treatment in patients with a gastric fistula.

Laparoscopic Sleeve Gastrectomy: A Radiological Guide to Common Postsurgical Failure

Laparoscopic sleeve gastrectomy is one of the most common bariatric procedures worldwide. It has recently gained in popularity because of a low complication rate, satisfactory resolution of comorbidities, and excellent weight loss outcome. This article reviews the surgical technique, expected postsurgical imaging appearance, and imaging findings of common complications after laparoscopic sleeve gastrectomy. Understanding of the surgical technique of laparoscopic sleeve gastrectomy and of the normal postsurgical anatomy allows accurate interpretation of imaging findings in cases of insufficient weight loss, weight regain, and postsurgical complications.

Efficacy and Safety of the Over-the-Scope Clip (OTSC) System in the Management of Leak and Fistula After Laparoscopic Sleeve Gastrectomy: a Systematic Review

BACKGROUND

Endoscopic management of leaks/fistulas after laparoscopic sleeve gastrectomy (LSG) is gaining popularity in the bariatric surgery.

OBJECTIVES

This study aimed to review the efficacy and safety of over-the-scope-clip (OTSC) system in endoscopic closure of post-LSG leak/fistula.

METHODS

PubMed/Medline and major journals of the field were systematically reviewed for studies on endoscopic closure of post-LSG leaks/fistula by means of the OTSC system.

RESULTS

A total of ten eligible studies including 195 patients with post-LSG leaks/fistula were identified. The time between LSG and leak/fistula ranged from 1 day to 803 days. Most of the leaks/fistula were located at the proximal staple line, and they sized from 3 to 20 mm. Time between leak diagnosis and OTSC clipping ranged from 0 to 271 days. Thirty-three out of 53 patients (63.5%) required one clip for closure of the lesion. Regarding the OTSC-related complications, a leak occurred in five patients (9.3%) and OTSC migration, stenosis, and tear each in one patient (1.8%). Of the 73 patients with post-LSG leak treated with OTSC, 63 patients had an overall successful closure (86.3%).

CONCLUSION

OTSC system is a promising endoscopic approach for management of post-LSG leaks in appropriately selected patients. Unfortunately, most studies are series with a small sample size, short-term follow-up, and mixed data of concomitant procedures with OTSC. Further studies should distinguish the net efficacy of the OTSC system from other concomitant procedures in treatment of post-LSG leak.

Staple line leak with peritonitis after laparoscopic sleeve gastrectomy - a solution in one to six steps

Introduction

Laparoscopic sleeve gastrectomy (LSG) is one of the most efficient bariatric interventions in morbidly obese patients. The most severe risk of this procedure seems to be the staple line leak, and the management of this complication can be very arduous.

Aim

To share our experience in managing the staple line leak after LSG and to help to find the best procedure that should be preferred.

Material and methods

In the 2010–2015 period we performed 223 LSG, with about 5 demonstrating severe complications – two patients with severe bleeding requiring revision surgery, and three patients with resection surface leak.

Results

We always primarily treated the staple line leak with a laparoscopic revision. Once the fistula did not spontaneously close after this treatment. A series of other methods were then indicated for this patient and only the sixth one resulted in the desirable therapeutic success. At first, our team opted for laparoscopic revision with drainage. The next procedure involved applying Ovesco and Boston clips. As a third method we performed abscess drainage through a nasobiliary tube inserted via gastroscopy. Due to failure we performed the second laparoscopic revision with staple line resuture, the next intervention was an open revision with fistula excision and suture, and finally we opted for the application of a self-expanding metallic stent, which proved to be definitely curative.

Conclusions

Without any guidelines it is very difficult to determine the right procedure addressing the staple line leak after LSG. It depends mainly on the clinician’s experience and is lengthy and often untraditional.
