Backgrounds/Aims: On the basis of acceptable oncologic results, ultralow anterior resection (ULAR) and colo-anal anastomosis plus hand-sewn coloanal anastomosis have been performed for treating very low-lying rectal cancer. However, many patients experience bowel dysfunction after ULAR. Studies have provided inadequate data on bowel dysfunctions and only a few functional studies have focused on low rectal cancer. Therefore, we aimed to elucidate the severity of bowel dysfunction after ULAR in a single-surgeon cohort. Methods: In this prospective observational study, we analyzed data of 203 patients who underwent sphincter-preserving surgery for low-lying rectal cancer (tumor located within 5 cm from the anus) between January 2011 and December 2014. During routine follow-up, examinations (3–6 months interval) after ileostomy closure, patients were asked about their bowel functions based on the Wexner incontinence and LAR syndrome (LARS) scores. Patients were divided into 2 groups: LAR group (LAR with double-stapled anastomosis) and ULAR group (ULAR with coloanal anastomosis), and functional scores were compared between 6 and 36 months. Seven risk factors for major LARS were analyzed. Results: At 36 months after surgery, 94.2 and 70.6% of patients in the ULAR group still had moderate to severe incontinence and major LARS respectively. Fecal incontinence improved significantly over time (ULAR group, 14.4 vs. 7.2, p = 0.045; LAR group, 13.9 vs. 5.4, p < 0.05). However, improvement in LARS over time was observed in the LAR group only (26.5 vs. 19.7, p = 0.045). In the ULAR group, the difference did not reach a statistical significance (33.6 vs. 26.0, p = 0.10). Major LARS and moderate incontinence were significantly higher in the ULAR group than in the LAR group (70.6 vs. 47.6%, p = 0.001; 82.4 vs. 32.0%, p = 0.012 respectively). Among the 7 factors evaluated in multivariable analysis, old age (> 70), male sex, ULAR per se, and chemoradiation therapy were found to be meaningful risk factors for major LARS. Conclusion: In patients with low rectal cancers undergoing ULAR plus coloanal anastomosis, bowel dysfunctions were severe. Bowel dysfunctions improved over time, but most patients still experienced major bowel dysfunctions even 36 months after surgery. Risk factors for bowel dysfunctions were old age, male sex, adjuvant chemoradiation therapy, and ULAR. Therefore, ULAR should be performed in carefully selected patients with low-lying rectal cancer.

Abstract Background Sphincter-preserving operations for ultra-low rectal cancer include low anterior resection and intersphincteric resection. In low anterior resection, the distal rectum is divided by a transabdominal approach, which is technically demanding. In intersphincteric resection, a perineal approach is performed. We aimed to evaluate whether robotic-assisted surgery is technically superior to laparoscopic surgery for ultra-low rectal cancer. The frequency of conducting low anterior resection by a specific procedure can indicate the technical superiority of that procedure for ultra-low rectal cancer. Thus, we compared the frequency of low anterior resection between robotic-assisted and laparoscopic surgery in cases of sphincter-preserving operations. Methods We investigated 183 patients who underwent sphincter-preserving robotic-assisted or laparoscopic surgery for ultra-low rectal cancer (lower border within 5 cm of the anal verge) between April 2010 and March 2020. The frequency of low anterior resection was compared between laparoscopic and robotic-assisted surgeries. The clinicopathological factors associated with an increase in performing low anterior resection were analyzed by multivariate analyses. Results Overall, 41 (22.4%) and 142 (77.6%) patients underwent laparoscopic and robotic-assisted surgery, respectively. Patient characteristics were similar between the groups. Low anterior resection was performed significantly more frequently in robotic-assisted surgery (67.6%) than in laparoscopic surgery (48.8%) (p = 0.04). Multivariate analyses showed that tumor distance from the anal verge (p < 0.01) and robotic-assisted surgery (p = 0.02) were significantly associated with an increase in the performance of low anterior resection. The rate of postoperative complications or pathological results was similar between the groups. Conclusions Compared with laparoscopic surgery, robotic-assisted surgery significantly increased the frequency of low anterior resection in sphincter-preserving operations for ultra-low rectal cancer. Robotic-assisted surgery has technical superiority over laparoscopic surgery for ultra-low rectal cancer treatment.

Abstract Background Anterior resection with total mesorectal excision (TME) of ultralow rectal cancer may result in the increased risk of the anastomotic leakage (AL). The aim of this study was to evaluate the usefulness of the gentamicin-collagen sponge (GCS) for the protection against symptomatic AL and investigate association between AL and local relapse (LR). Patients and methods A series of 158 patients with ultralow rectal cancer was studied. All the patients underwent R0 sphincter-saving TME with anastomosis wrapping using GCS. In none of the cases a temporary protective stoma was constructed. Results AL rate was 3.2% (5/158) while median time to AL diagnosis was 5 days following surgery (range 3-15). There was no postoperative and leakage-related mortality. Patient age > 75 years and smoking were independent risk factors related to significantly increased AL rate: 12.5% vs. 0.8% (P = 0.0004) and 5.7% vs. 0% P = 0.043), respectively. LR was observed in 12% of cases. It was highly significantly more common and developed earlier in patients who have had AL when compared with non-AL group: 80% vs. 9% (P = 0.00001) and 8.5 vs. 17 months (P = 0.014), respectively. Conclusions Anastomosis wrapping with GCS after anterior resection with TME is a safe procedure resulting in the low incidence of anastomotic leakage which may be also associated with decreased risk of local relapse.
