325. Functional Results After Electrostimulation of Anal Sphincter After Low Anterior Resection

Abstract Purpose Improved long-term survival after low anterior resection (LAR) for rectal cancer highlights the importance of functional outcome. Urogenital and anorectal dysfunction is frequently reported after conventional LAR. Advanced minimally invasive techniques such as robotic (RoTME) and transanal total mesorectal excision (TaTME) might improve functional results by precisely dissecting and preserving autonomic nerves. We compared functional outcomes after RoTME or TaTME in a multicenter study. Methods One hundred twenty patients (55 RoTME/65 TaTME) were prospectively included in four participating centers. Anorectal (Wexner and low anterior resection syndrome (LARS) Score), urinary (International Consultation on Incontinence—Male/Female Lower Urinary Tract Symptoms Score (ICIQ-MLUTS/ICIQ-FLUTS) and International Prostate Symptom Scale (IPSS)), and sexual (International Index of Erectile Function (IIEF), Female Sexual Function Index (FSFI)) outcomes at 12 months after surgery were compared to preoperative scores. The response rate to the 1-year postoperative functional assessment by questionnaire was 79.5%. Results RoTME enabled better anorectal function compared to TaTME (LARS score 4.3 ± 2.2 vs. 9.8 ± 1.5, p = 0.038, respectively). TaTME proved superior at preserving male urinary function, while female urinary function was comparable in both groups, with only mild postoperative impairment (RoTME vs. TaTME, respectively: ICIQ-MLUTS 13.8 ± 4.9 vs. 1.8 ± 5.8, p = 0.038; ICIQ-FLUTS Incontinence Score − 0.3 ± 1.0 vs. − 0.2 ± 0.9, p = 0.844). Both techniques demonstrated comparable male (RoTME − 13.4 ± 2.7 vs. TaTME − 11.7 ± 3.4, p = 0.615) and female (RoTME 5.2 ± 4.6 vs. TaTME 10.5 ± 6.4, p = 0.254) sexual function. Conclusion After adjustment for risk factors, RoTME provided better anorectal functional results, whereas TaTME was better at preserving male urinary function. Overall, both techniques demonstrated only mild postoperative functional impairment.

Cumulative Function

For many decades the main goal of oncologists was to increase life expectancy of patients with malignant tumors, without paying due attention to quality of life. Currently, the goals of patients’ treatment with rectal cancer are to cure, to minimize the risk of local recurrence, preserve the normal course of intestine, to optimize it's function and to ensure quality of life. For a long time, the standard surgical treatment of patients with low rectal cancer was abdominoperineal extirpation, but recently sphincterosafing operations have seen a widespread introduction in surgical practice. However, functional results after these types of operations don't always meet the expectations of surgeons and patients. In the postoperative period, patients often develop a syndrome of low anterior resection, characterized by frequent bowel movements, repeated, prolonged and incomplete evacuation of bowel and the imperative urge to defecate. The manifestation of this syndrome can significantly impair the quality of patient's life and reduce to nothing the efforts of the surgeon to preserve the sphincter of the rectum. For surgical correction of low anterior resection syndrome, various types of colonic reservoir anastomoses have been proposed. The purpose of formation of colonic reservoirs is to increase the cumulative function of intestine. However, the existing methods have several disadvantages related to technical complications and the risk of developing evacuation dysfunction, which is the reason for search the new ways of optimization of anastomoses when performing sphincterotomy operations for cancer of the rectum.

Mechanical Anastomosis

Background and aims. Colorectal cancer is one of the most frequent digestive malignancies, being the third cause of death by cancer, despite early diagnosis and therapeutic progress made over the past years. Standard treatment in these patients is to preserve the anal sphincter with restoration of intestinal function by mechanical colorectal anastomosis or coloanal anastomosis, and to maintain genitourinary function by preservation of hypogastric nerves.Methods. In order to emphasize the importance of this surgical technique in the Fourth Surgical Clinic of the CF Clinical Hospital Cluj-Napoca, we conducted a prospective observational interventional study over a 3-year period (2013-2016) in 165 patients hospitalized for rectal and rectosigmoid adenocarcinoma in various disease stages, who underwent Dixon surgery using the two techniques of manual and mechanical end-to-end anastomosis. For mechanical anastomosis, we used Covidien and Panther circular staplers. The patients were assigned to two groups, group A in which Dixon surgery with manual end-to-end anastomosis was performed (116 patients), and group B in which Dixon surgery with mechanical end-to-end anastomosis was carried out (49 patients).Results. Mechanical anastomosis allowed to restore intestinal continuity following low anterior resection in 21 patients with lower rectal adenocarcinoma compared to 2 patients in whom intestinal continuity was restored by manual anastomosis, with a statistically significant difference (p<0.000001). The double-row mechanical suture technique is associated with a reduced duration of surgery (121.67 minutes for Dixon surgery with mechanical anastomosis, compared to 165.931 minutes for Dixon surgery with manual anastomosis, p<0.0001).Conclusion. The use of circular transanal staplers facilitates end-to-end anastomosis by double-row mechanical suture, allowing to perform low anterior resection in situations when the restoration of intestinal continuity by manual anastomosis is technically not possible, with the aim to preserve the anal sphincter, to restore intestinal function and maintain genitourinary function through preservation of hypogastric nerves.

Introduction. Functional results after low anterior resection for rectal cancer are an issue of increasing attention among colorectal surgeons and others interested in this subject. The consensus on ideal reconstruction type has not been achieved to date, although the number of papers on this subject has been published in recent years. Objective. We conducted a prospective, parallel group study comparing latero-terminal with colonic J-pouch anastomosis in terms of defecatory function in patients undergoing stapled low colorectal/ coloanal anastomosis. Methods. A total of 80 patients were included in this study with either latero-terminal or colonic J-pouch anastomosis. Defecatory function was evaluated using the modified version of MSKCC questionnaire 6, 12 and 24 months after the operation. Fecal continence was evaluated using the Wexner continence score. Results. In both groups, trend towards improvement was registered in all measured variables in all three control intervals. This can apply to bowel frequency, urgency, night soiling, fragmentation and incomplete evacuation. However, the difference was not statistically significant, and when reviewing the trend of results we can note that in the J-pouch group steady state has not been reached even after 24 month control. Conclusion. This trial did not reveal any significant differences in defecatory function 6, 12 and 24 months after low anterior resection (LAR) between patients with a latero-terminal anastomosis and those with colonic J-pouch anastomosis. Our results did not confirm superiority of colonic J-pouch over the lateroterminal anastomosis.
