Performance of the OTSC System in the endoscopic closure of gastrointestinal fistulae - a meta-analysis

Abstract

Endoscopic closure of gastrointestinal fistulae by means of the OTSC System is a safe and effective method.

Usefulness of over‐the‐scope clipping system for closing digestive fistulas

“…In the literature, we found some predictive criteria for fistula closure success using OTSC as follows: very early fistula (<7 days); fistulas with less fibrosis, leak size 10–30 mm; and leakages after LSG . Our work showed better efficiency of OTSC on fistulas after LSG ( P = 0.01), but we could not confirm the other factors.…”

“…Thus, new clipping devices such as OTSC (Ovesco Endoscopy, Tübingen, Germany) are recently being used as a good alternative to standard clips because one single clip allows steady closure of perforations ≤2.5 cm. In the clinical setting, the OTSC device has gained popularity during the past 6 years for its promising results in the sealing of digestive fistulas …”

“…In the clinical setting, the OTSC device has gained popularity during the past 6 years for its promising results in the sealing of digestive fistulas. [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] The aim of the present study is to describe our 2-year experience of 30 patients treated for digestive fistula using the OTSC device. We report technical and clinical efficacy, adverse events encountered and compare the effectiveness according to the different causes of fistula (especially leaks after laparoscopic sleeve gastrectomy).…”

Transanal endoscopic microsurgery for surgical repair of rectovesical fistula following radical prostatectomy

“…Recently, some favorable results by transanal approach using flexible colonoscopy with a newly developed clip [15,16] have been reported [17,18]. When we know to which type of fistula this kind of endoscopic treatment is appropriately indicated, this procedure should be regarded as minimally invasive choice of treatment and beneficial to the indicated patients.…”

Endoscopic Closure of a Large Rectovesical Fistula Following Robotic Prostatectomy

“…However, two factors have hindered researchers from comparing the various treatment modalities for closure of RVF, including the heterogeneity of the underlying etiologies causing RVF and the infrequency in which they occur. 3 One meta-analysis by Weiland et al found that using the OTSC system in the endoscopic closure of GI fistulae was safe, feasible, and had a clinical success rate of 69%. In addition, repeat OTSC procedures after initial clinical failure may further increase the success rate.…”
