Colorectal large-cell neuroendocrine carcinomas (NECs) are extremely rare and have very poor prognosis compared to adenocarcinomas. A 74-year-old man presented with abdominal pain, diarrhea and hematochezia. The histopathologic report of colonoscopic biopsy performed at a local clinic was a poorly differentiated carcinoma. An abdominopelvic computed scan revealed irregularly enhanced wall thickening at the sigmoid colon with regional fat stranding and lymphnode enlargement. He underwent a laparoscopic high anterior resection with selective peritonectomy for peritoneal carcinomatosis, intraoperative peritoneal irrigation chemotherapy, and early postoperative intraperitoneal chemotherapy for 5 days. The tumor had a high proliferation rate (mitotic count > 50/10 HPFs and 90% of the Ki-67 index) and lymph-node metastases had occurred. On immunohistochemistry, the tumor cells expressed CD56 and synaptophysin. Large-cell NEC was confirmed. Systemic chemotherapy with cisplatin/etoposide was done. The patient is still alive after 3 years with no evidence of recurrence.

Abstract PDF

Rectourethral fistulas (RUFs) in adults are rare and could result from complicated trauma, and prostatic or rectal surgery. RUFs have been treated initially by using primary repair and omental interposition with or without a colostomy during surgery. Recurrent RUFs require complex surgery, such as a low rectal resection and coloanal anastomosis, an interposition flap of the datos muscle or gracilis muscle, and others. Recently, transanal rectal flap advancement and fibrin glue injection have provided an effective occlusion of RUFs. However, no reports about this technique exist for cases of recurrent RUFs. We report a case of a recurrent RUF successfully repaired by using transanal rectal flap advancement combined with fibrin glue injection into the fistula tract. The postoperative course was uneventful without complications. At the 1-year follow-up, no complications such as urethral stricture or recurrence existed, and voiding was normal without anal incontinence.
