RESUMO
The patient is a 70s woman. She underwent cystectomy for bladder cancer 6 years ago and had a ureterocutaneous fistula in the right lower abdomen. After colonoscopy for positive fecal occult blood, a type 1 elevated lesion was found in the ascending colon, which was diagnosed as a well-differentiated adenocarcinoma on biopsy. Surgery was performed with a single hole. The approach from the right lower abdomen, where the ureterocutaneous fistula and ureter are located, was avoided, and the approach from the hepatic flexure of the transverse colon was used first. After the right colon was mobilized, the large mesh adhesions around the ureter were carefully dissected, and the right ureter was identified and preserved, extending from the lateral ascending colon to the abdominal wall. The ileal artery was dissected at the root and after dissection of the D3 lymph node, the intestine was dissected and anastomosed extracorporeally. The operative time was 246 minutes with small amount of blood loss. The patient was discharged on the 6th postoperative day without any postoperative complications. The pathology result was pT3N0M0, pStage â ¡a, and radical resection had been performed. The patient is currently undergoing recurrence-free follow-up.
