[Short- and long-term results of sphincter preserving operations with creation of colonic J-reservoir].

The aim of this study was to evaluate short- and long-term results of sphincter preserving operations with forming a colonic J-reservoir. This study examined the results of the treatment of 63 patients with medioampullary carcinoma of the rectum. Sphincter preserving operations with forming a reservoiroanal anastomosis were made in 34 patients (test group), 29 patients had sphincter preserving operations with forming coloanal and supraanal colorectal anastomoses (control group). In the test group complications were observed in 6 (17.6%) patients and in the control group in 6 (20.7%) patients (p = 0.3962). The defecation frequency in the test group 3 months after the operation was 1.87 +/- (1-3) time a day, in the control group even through 12 months--3.0 +/- 1.5 times a day (p = 0.0001). In terms up to 6 months tenesmus, imperative desire to defecate and defecation's multistage more often disturbed the patients of the control group (p = 0.0005). The function of the faeces continence was satisfactory in both the patients' groups, however in the control group the events of the anal incontinence of I-II degree (p > 0.05) occurred more often. The negative aspect of the colonic reservoir's forming is frequent change of the evacuation function with constipation, however, the differences were statistically insignificant (p > 0.05). Creation of a colonic reservoir doesn't increase lethality and postoperative complications rate, allows to reduce clinical manifestations of a "low anterior resection" syndrome.
