Ileal conduit necrosis after total pelvic exenteration for recurrence of gastrointestinal stromal tumor.

We report a case of ileal conduit necrosis after total pelvic exenteration for recurrence of gastrointestinal stromal tumor. A 47-year-old man was diagnosed with recurrence of gastrointestinal stromal tumor adjacent to the prostate after abdominoperineal resection 10 years prior. With imatinib administration for 18 months, the local recurrence decreased in size but did not separate from the prostate.

Surgical Strategy for Rectovaginal Fistula After Colorectal Anastomosis at a High-volume Cancer Center According to Image Type and Colonoscopy Findings.

Background/aim: The reported incidence of rectovaginal fistula is very low. Although some case reports have described surgical procedures, no systematic approach to the treatment of rectovaginal fistula according to diagnostic image and colonoscopy findings has been proposed. We present a comprehensive surgical strategy for rectovaginal fistula after colorectal anastomosis according to diagnostic image and colonoscopy findings.

[A Case of Metastatic Colorectal Cancer with Brain Metastasis Treated with Combined TFTD and Bevacizumab Therapy].

A woman in her 70s was confirmed as presenting with multiple liver and lung metastases from transverse colon cancer. After undergoing resection of the primary lesion, partial response(PR)was achieved after undergoing the first regimen (sLV5FU2 and bevacizumab[Bmab]); therefore, partial hepatectomy was performed. Adjuvant chemotherapy was administered for 7 months, but liver metastasis recurrence, multiple lung metastases, and brain metastasis were confirmed.
