    Abstract:
    BACKGROUND: Needlescopic surgery is a minimally invasive procedure that uses thin trocars with 3-mm diameter. We used Turnbull-Cutait pull-through and delayed coloanal anastomosis in needlescopic surgery to avoid diverting ileostomy during intersphincteric resection for low rectal cancer. In this study, we aim to assess the diverting ileostomy avoidance rate and technical safety of this "minimal skin incision and no stoma" procedure. METHODS: This single-center retrospective study was conducted at the Cancer Institute Hospital, a tertiary referral center in Japan. Between January 2017 and December 2020, 11 patients underwent needlescopic intersphincteric resection with diverting ileostomy (NSI group), and 19 patients underwent needlescopic intersphincteric resection with delayed coloanal anastomosis (NSD group) for low rectal cancer. Data regarding patient backgrounds and short-term outcomes, including diverting ileostomy avoidance rate, pathological results, and postoperative defecatory function, were compared between the groups. RESULTS: There were no statistically significant differences between the NSI and NSD groups with respect to patient background, operation time (239 min versus 220 min, p = 0.68), estimated blood loss (45 g versus 25 g, p = 0.29), R0 resection rate (100% versus 100%, p = 1.00), and length of postoperative hospital stay (16 days versus 17 days, p = 0.42). The diverting ileostomy avoidance rate was 94.4% in the NSD group. The LARS and Wexner scores 12 months after surgery were not significantly different between the two groups. CONCLUSIONS: Needlescopic intersphincteric resection and delayed coloanal anastomosis can be safely performed in selected patients with a high rate of diverting ileostomy avoidance and comparable short-term outcomes.
