Long-Term Functional and Oncological Outcomes Following Intersphincteric Resection for Low Rectal Cancers

Long-Term Functional and Oncological Outcomes Following Intersphincteric Resection for Low Rectal... Abstract Surgery for low rectal cancer often involves a permanent stoma. Intersphincteric resection (ISR) with colo-anal anastomosis is a valuable sphincter sparing surgical procedure that avoids the need for permanent stoma in patients with low rectal cancer. The aim of this study was to analyze the long-term functional and oncological outcomes following ISR. This was a retrospective analysis of patients with low rectal cancer who underwent ISR with colo-anal anastomosis in our institution between 2007 and 2015. All patients had a diversion stoma. Bowel function outcomes were assessed prospectively using Wexner incontinence score, low anterior resection syndrome score (LARS), and the Cancer Institute Quality of Life (QoL) questionnaire. The histological reports were reviewed to assess the oncological adequacy of the surgery. Patterns of recurrence and survival were analyzed in this group of patients. Thirty-three patients who underwent an ISR were eligible for this study. Laparoscopic resection was performed in five patients. All the patients received neoadjuvant chemoradiation except the two who received short course radiation and one who did not receive any neoadjuvant treatment. The median distance from the anal verge to the distal edge of the tumor was 3 cm (range 1.5–5 cm). Distal resection margins and circumferential resection margins were negative in all the patients. The 30-day post-operative mortality rate was 3.03%. In 20 patients with a median follow-up of 48 months, the 3-year overall survival was 95%. One patient had recurrence in the para-aortic nodes.

Abstract

Abstract Surgery for low rectal cancer often involves a permanent stoma. Intersphincteric resection (ISR) with colo-anal anastomosis is a valuable sphincter sparing surgical procedure that avoids the need for permanent stoma in patients with low rectal cancer. The aim of this study was to analyze the long-term functional and oncological outcomes following ISR. This was a retrospective analysis of patients with low rectal cancer who underwent ISR with colo-anal anastomosis in our institution between 2007 and 2015. All patients had a diversion stoma. Bowel function outcomes were assessed prospectively using Wexner incontinence score, low anterior resection syndrome score (LARS), and the Cancer Institute Quality of Life (QoL) questionnaire. The histological reports were reviewed to assess the oncological adequacy of the surgery. Patterns of recurrence and survival were analyzed in this group of patients. Thirty-three patients who underwent an ISR were eligible for this study. Laparoscopic resection was performed in five patients. All the patients received neoadjuvant chemoradiation except the two who received short course radiation and one who did not receive any neoadjuvant treatment. The median distance from the anal verge to the distal edge of the tumor was 3 cm (range 1.5–5 cm). Distal resection margins and circumferential resection margins were negative in all the patients. The 30-day post-operative mortality rate was 3.03%. In 20 patients with a median follow-up of 48 months, the 3-year overall survival was 95%. One patient had recurrence in the para-aortic nodes. No patient had a local recurrence. Bowel function was assessed in 18 patients who had a minimum stoma free period of 1 year. After a median of 43 months following stoma closure, the median Wexner score was 3.56 (range 0–19), median LARS score was 4.78 (range 0–33), and the mean Cancer Institute QoL score was 151.56 ± 15.741. The QoL was average to very high with an overall acceptable quality of life. In this study, ISR was associated with acceptable long-term functional and oncological outcomes. It can be considered as a safe alternative to a permanent stoma in selected patients with low rectal cancer.
