Endoscopic Kehr’s T-Tube Placement to Treat Persistent Large Gastro-cutaneous Fistula After One Anastomosis Gastric Bypass: Video Demonstration

Abstract

Abstract Background We aim to show the endoscopic placement of a T-tube to treat a persistent large gastro-cutaneous fistula after OAGB. Methods We present the case of a 46-year-old woman with BMI of 48 kg/m2, who underwent OAGB and was re-operated on the 2nd postoperative day (POD) for leakage. Washing and drainage of the abdominal cavity was performed, and no fistulous orifice was identified. An upper gastrointestinal (GI) endoscopy was performed at POD 20 for the persistence of leakage of 150 ml/day by the drain and a gastric fistulous orifice of 2 cm was detected. Results At POD 22, under general anesthesia, upper GI endoscopy was performed and a T-tube was placed in the fistulous orifice with a “rendez-vous” technique (as demonstrated in the Video), placing the T branch in the digestive lumen pressed against the wall and the long part of the T exiting at the cutaneous orifice. The T-tube was clamped after 3 days and the patient could be gradually re-fed. The patient was discharged 8 days after the procedure, with perfect clinical tolerance and no complications. The ablation of the tube one was performed on POD 84. No relapse occurred during a follow-up of 48 months. Conclusion Persistent large gastro-cutaneous fistulas with an orifice bigger than 1 cm in diameter are difficult to manage. The endoscopic placement of a T-tube seems a useful option, which may facilitate the healing of the fistula. Further studies are needed to better define the role of this procedure.
