Use of an Endoscopic Suturing Platform for the Management of Staple Line Dehiscence After Laparoscopic Sleeve Gastrectomy.

Background: Management of staple line dehiscence following laparoscopic sleeve gastrectomy (LSG) varies based on local expertise and timing of presentation. We present our experience with an endoscopic suturing platform to treat patients with staple line dehiscence following LSG.
Methods: We included all patients who presented to our institution with a staple line dehiscence following LSG from 2005 through November 2017. All endoscopic suturing procedures were performed by a single interventional endoscopist.
Results: Five patients, ages 25-69 years, received treatment of staple line dehiscence at a median time of 22 days following LSG (range 13-335 days). Four out of the five patients received a stent at some point during their treatment. One patient with a chronic leak required gastrectomy and esophago-jejunostomy as a definitive treatment. The remaining four patients experienced resolution of the leak at a median of 48 days post-operatively (range 21-82 days).
Conclusion: Endoscopic suturing may have a role in the management of leaks following LSG, as a primary treatment or as an adjunct to treatment with a stent. However, given that the technique requires considerable endoscopic expertise and in light of a number of other available therapeutic choices, further studies are required to better define the role of this technology in the algorithm of LSG-related leak management.
