Usefulness of over-the-scope clipping system for closing digestive fistulas.

BACKGROUND AND AIM: Therapeutic endoscopy has recently evolved into the treatment of complex gastrointestinal (GI) postoperative leakage, especially with over-the-scope clips (OTSC). We describe our 2-year experience of 30 patients treated for digestive fistulas using the OTSC device. METHODS: This was a retrospective study conducted on patients referred for GI fistulas in two French hospitals. Technical aspects, clinical outcomes and closure rates were recorded. RESULTS: Thirty patients were treated for GI leaks: 19 (63%) had a gastric fistula after laparoscopic sleeve gastrectomy (LSG); the others had rectovaginal, urethrorectal, rectovesical, gastrogastric, gastrocutaneous, esophagojejunal fistulas and colorectal anastomotic leak. Average follow up was 10.4 months. Eighteen (60%) had undergone previous endoscopic or surgical treatment. Orifice size was 3-20 mm (average 7.2 mm). Successful OTSC placement was achieved in 30 out of 34 attempts. There were four intraoperative undesired events (13.3%) but these were successfully managed. Overall success rate was 71.4% and 16 patients (53%) recovered with primary efficacy. Six patients (20%) required a subsequent endoscopic treatment. Eight patients (26.7%) required surgery for failure. In nine cases, we used one or more additional endoscopic procedures concomitantly with the OTSC combining self-expandable metal stents, standard clips and glue injection. Healing rate after LSG fistula was 88.9%, which was significantly higher than the overall rate (P = 0.01). CONCLUSION: OTSC placement seems to be safe and effective for the treatment of GI fistulas. Better results were seen in leaks after LSG.

Use of a tunnelled pleural catheter for the management of refractory hepatic hydrothorax: a new therapeutic option.

Refractory hepatic hydrothorax poses a challenging therapeutic dilemma, as treatment options are limited. Herein, we describe the case of a 48-year-old lady with advanced cirrhosis and recurrent transudative pleural effusion despite a sodium-restricted diet, optimal diuretic therapy and transjugular intrahepatic portosystemic shunt. Given the patient's platelet and coagulation disorders, thoracoscopic pleurodesis was deemed unsafe. Instead, a tunneled pleural catheter (PleurX®) was inserted under local anesthesia. Pleural drainage was achieved at the time of catheter placement and subsequently according to the patient's symptoms. Symptomatic improvement and gradual decrease of drainage volumes were noted. Six months following placement of PleurX, methicillin-resistant Staphylococcus aureus cellulitis at the insertion site prompted catheter removal. No pleural effusion was seen on chest X-ray at that time. Subsequent follow-up revealed spontaneous pleurodesis, as no recurrence of pleural effusion was seen over a 6-month follow-up period. Very few data are available with regard to the use of indwelling pleural catheters for benign transudative pleural effusion, and more specifically hepatic hydrothorax. Herein, we present this novel potential indication of the indwelling pleural catheter and illustrate the successful clinical outcome.
