Endoscopic management of post-surgical GI wall defects with the overstitch endosuturing system: a single-center experience

Research output: Contribution to journalArticle

Abstract

Background and aims: Post-GI surgical wall defects are frequent and life-threatening complications, with limited literature regarding current treatment. This case series aims to assess the safety, feasibility, and outcomes of endoluminal therapy with the overstitch endoscopic suturing system (Apollo Endosurgery Inc, Austin). Materials and methods: All patients who underwent endoscopic suturing for post-surgical wall defect management at IRCCS-ISMETT Palermo from October 2017 until January 2019 were retrospectively enrolled. Stratification therapy was applied according to the clinical scenario, time from surgery to endoscopic intervention, and structural condition of the wall defect layers (tissue status and suture feasibility). The therapeutic endoscopic strategy was divided into three groups (A: pure endoscopic direct suture; B: combined therapy with endoscopic direct suture + FC-SEMS placement + anchoring; C: FC-SEMS placement + anchoring). Success was considered the resolution of symptoms and the presence of a regular intestinal transit after a period of 4–6 weeks. Results: Twenty (20) patients (male/female 7/13; mean age 54 ± 13.43 years) were included in the study (group A: 9 patients, group B: 7 patients, group C: 4 patients). The types of operative procedures were bariatric (9/20), post-tracheostomy (3/20), post-operative GI surgery (8/20). The post-surgical defects were predominantly intermediate and chronic (24–72 h: 1/20; 3–30 days: 13/20; > 30 days: 6/20). The overall clinical success was 80% (17/20 patients), with a success of 94% (16/17 patients) when excluding the three cases of tracheo-esophageal fistula. No evidence of migration was detected. The only complication was short stenosis of the distal esophagus, present in 4 patients (19%) and successfully treated with a novel lumen-apposing metal stent. Conclusions: In our experience, considering the absence of clear guidelines, the endoluminal approach with the overstich endoscopic suturing system is a valid alternative to conventional therapy, offering mini-invasiveness, and presenting promising opportunities in terms of technical feasibility and clinical efficacy.
