[Results of reconstructive surgery with formation of low colorectal anastomoses after previous Hartmann's procedure].

Abstract

To evaluate the efficacy and safety of original access to short rectal stump compared to traditional direct one. A retrospective-prospective cohort comparative study was conducted between 2012 and 2018. Inclusion criterion was previous Hartmann's procedure with formation of a short rectal stump. Short stump was determined by its length from anal-skin line to the cupola <7 cm. There were 93 patients who were divided into 2 groups: the main group - new approach (n=38), the control group - traditional direct approach (n=55). We analyzed surgery time, blood loss, intraoperative, early and late postoperative morbidity. Surgery time and blood loss were similar in both groups (299.9 vs. 288.3 min, p=0.82; 204.5 vs. 112.4 ml, p=0.94, respectively). Intraoperative complications occurred in 7 patients of the control group (0 vs. 12.7% (7/55), p=0.02). Incidence of early postoperative complications was similar (28.9% (11/38) vs. 25.5% (14/55), p=0.71). Adverse events Clavien-Dindo grade I and IIIa were more common in the main group, grade IIIb and IVa - in the control group. Incidence of delayed postoperative complications were similar (10.5% (4/38) vs. 7.3% (4/55), p=0.58). Colorectal anastomosis stricture prevailed in the control group, ureteral stricture - in the main group. Neurophysiological and complex urodynamic examinations revealed no between-group differences. The new method ensures access to the rectal stump and formation of colorectal anastomosis under direct visual control. Postoperative outcomes demonstrated safety and effectiveness of this technique.
