Treatment of Persistent Large Gastrocutaneous Fistulas After Bariatric Surgery: Preliminary Experience with Endoscopic Kehr’s T-Tube Placement

Purpose Post-bariatric surgery gastrocutaneous fistula is a chronic leak with an incidence of 1.7 to 4.0% and no standardized management. A large gastrocutaneous fistula (LGCF) is not indicated for treatment with pigtail drains. We aimed to evaluate results of a novel treatment using endoscopic Kehr...

Zusammenfassung:Purpose Post-bariatric surgery gastrocutaneous fistula is a chronic leak with an incidence of 1.7 to 4.0% and no standardized management. A large gastrocutaneous fistula (LGCF) is not indicated for treatment with pigtail drains. We aimed to evaluate results of a novel treatment using endoscopic Kehr’s T-tube placement. Methods Only patients with a postoperative LGCF duration of > 10 days and a flow rate of > 50 cc by external drainage after revisional surgery for sepsis were included. Endoscopic placement of Kehr’s T-tube was performed. Patients had been reoperated with wash and drainage for severe sepsis after initial bariatric surgery in which no fistula had been discovered. Patients not reoperated, or with a fistula requiring intraoperative Kehr’s T-tube placement, or a pigtail drain were excluded. Primary outcomes were endoscopic characteristics and results (LGCF closure rate, Kehr T-tube retention time, etc.). Results The study group included 12 women, 2 men; body mass index 43.1 ± 4.5 kg/m 2 . Interventions were SG (7), RYGB (2), OAGB (4), and SADI-S (1). Endoscopic assessment was carried out after a mean of 33.2 ± 44.3 days after the bariatric procedure. The mean fistula orifice diameter was 2.0 ± 0.9 cm. Kehr’s T-tube was positioned at a mean 51.5 ± 54.8 days after the bariatric procedure. T-tube tolerance was excellent. Mean additional days: hospitalization, 34.4 ± 27.0; T-tube retention, 86.4 ± 73.1; fistula healing, 139.9 ± 111.5, LGCF closure rate, 92.9%. Complications: 1 pulmonary embolism, 2 T-tube migrations,1 drain-path bleed, 1 skin abscess. No mortality. Conclusions Endoscopic Kehr’s T-tube placement was successful in closing persistent post-bariatric surgery LGCF in 92.9% of patients. Graphical abstract
