Elective subtotal colectomy with ileosigmoid anastomosis for colon cancer preserves bowel function and quality of life.

ABSTRACT

AIM: We report on our experience of elective subtotal colectomy and ileosigmoid anastomosis for colon cancer with focus on postoperative results, function and quality of life. METHOD: Between 1998 and 2011, 106 consecutive patients with colonic malignancy underwent this procedure electively. Function and quality of life (EORTC QLQ-C30) were evaluated retrospectively with questionnaires sent to all patients free of recurrence. RESULTS: There were 62 men and 44 women (mean age 63 years). Postoperative mortality and morbidity rates were 1.9 and 26.4%, respectively. Persistent ileus was the main early complication (16%). After a mean follow-up of 67 ± 36 months, 50 (78.1) out of 64 patients have been evaluated for function and quality of life. The mean number of bowel movements per 24 h was 3 ± 2 and significantly lower when the length of the remaining sigmoid colon was more than 15 cm (P = 0.049). Compared with a European reference population for EORTC QLQ-C30 results, our patients had significantly more diarrhoea (26 vs 3, P = 0.0002) but less pain (10 vs 25, P < 0.0001) and better global quality of life (77 vs 62, P < 0.0001). CONCLUSION: Elective subtotal colectomy for colon cancer is safe and associated with good function and quality of life. Ileosigmoid anastomosis should be discussed when extended colectomy is required, providing the rectosigmoid junction and its vascular supply can be oncologically preserved. For tumours located in the transverse colon or at the splenic flexure, this procedure may be the best surgical option.
