Feasibility of Laparoscopic and Robotic Total Proctocolectomy for Ulcerative Colitis-related Colorectal Cancer.

BACKGROUND/AIM: To evaluate the feasibility of laparoscopic and robotic total proctocolectomy (TPC) for ulcerative colitis-associated colorectal cancer (UC-CRC).

PATIENTS AND

METHODS

We retrospectively analyzed the postoperative outcomes of TPC in 13 patients with UC-CRC between January 2011 and December 2021. Laparoscopic TPC was performed in 10 patients. TPC consisted of two procedures: ileal pouch-anal anastomosis (IAA) and TPC with end ileostomy. Using the da Vinci Xi platform with six ports, robotic TPC and abdominal perineal resection (APR) were performed in two and one patients, respectively. Transanal total mesorectal excision (TaTME) was performed using the perineal approach in five patients.

RESULTS

UC-CRC was located in the transverse colon, sigmoid colon, rectum, and anal canal in 1, 1, 10, and 1 patients, respectively. IAA, TPC with end ileostomy, and APR were performed in nine, three, and one patients, respectively. Postoperative complications included colitis, portal vein thrombosis, and liver dysfunction, without mortality. The pathological stages were 0, I, IIa, IIIb, and IIIc in five, four, one, two, and one patients, respectively. The tumors were completely resected in all cases. Eleven patients with pStages 0, I, and II survived without recurrence; however, two patients with pStage III died of cancer recurrence.

CONCLUSION

This study demonstrated the feasibility of laparoscopic and robotic TPC in patients with UC-CRC. However, long-term outcomes in terms of oncology and patient quality of life must be investigated in future large-scale studies.
