چکیده

Laparoscopic multi-visceral resection in patients with T4 colorectal cancer remains controversial. A 73-year-old man was admitted to the hospital for rectosigmoid cancer directly invading the urinary bladder trigone without distant metastasis. We successfully performed complete resection by laparoscopic anterior pelvic exenteration while preserving the anus. After laparoscopic mobilization of the rectum, urinary bladder, and prostate, the urethra and urethral catheter were dissected to reveal the lower rectum. By pulling the urethral catheter toward the head, the prostate was excised retrogradely from the lower rectum anterior wall. The lower rectum was resected and anastomosed by the double stapling technique with a safe distal margin from the tumor. Pathological findings of the resected specimen indicated no residual tumor in the surgical margin. There was no evidence of recurrence 34 months after surgery. En bloc, R0, laparoscopic anterior pelvic exenteration for T4 rectal cancer is feasible. However, further studies with long-term follow-up are required to resolve oncological outcomes.

Complications and Outcome of Pelvic Exenteration in Thai Gynecologic Oncology Patients

Pelvic exenteration is a radical surgery which includes the en bloc resection of the pelvic organs and followed by surgical reconstruction (Hockel et al., 2006; Diver et al., 2012). The en bloc resection includes internal reproductive organs, rectosigmoid colon, urinary bladder and distal ureters. Pelvic exenteration is classified into 3 types; anterior pelvic exenteration, posterior pelvic exe...

Total pelvic exenteration for pelvic recurrence after advanced epithelial ovarian cancer – A case report and literature review

Ovarian cancer is an aggressive disease, which, although associated with a high rate of recurrence, seems to benefit most from iterative cytoreduction. Although the main patterns of its spreading are represented by peritoneal, lymphatic or hematogenous route, local recurrences might also be seen. Whenever pelvic recurrence develops, complete resections based on the ultraradical principles appli...

Pelvic intraoperative neuromonitoring during robotic-assisted low anterior resection for rectal cancer

While the oncological outcome of patients with rectal cancer has been considerably improved within the last decades, anorectal, urinary and sexual functions remained impaired at high levels, regardless of whether radical surgery was performed open or laparoscopically. Consequently, intraoperative monitoring of the autonomic pelvic nerves with simultaneous electromyography of the internal anal s...
