Complex intestinal fistula treated with colon­indwelling drainage stent under prostate resection endoscopy instrumentation guidance: A case report.

ABSTRACT

The treatment of complex intestinal fistulas has been a challenge in general surgery. A complex fistula is defined as a fistula with more than one abnormal connection between the gastrointestinal tract and skin, or a fistula with multiple bowel loops. The present case report describes the minimally invasive treatment of a complex intestinal fistula. Briefly, a 51-year-old man presented with an intestinal fistula. Following adequate anti-infective drainage of the abdominal abscess, transurethral prostate resection instrumentation was used to flush and drain the intestinal drainage tubes. On reduction of leakage, a drainage tube was inserted into the intestinal tract to serve as an internal stent. Imaging confirmed the successful cessation of intestinal leakage and a satisfactory recovery. The drainage tube was removed under colonoscopy, restoring normal small intestine function. To summarize, after sufficient drainage, the leakage gradually decreased, promoting healing; the patient achieved full recovery upon removal of the internal stent via colonoscopy and the establishment of a small intestinal stoma. In conclusion, transurethral prostate resection instrumentation enables safe and minimally invasive placement of intestinal stents, ensuring effective drainage for managing intestinal fistulas.
