[Formation of a colonic reservoir while performing a low anterior resection of the rectum].

The aim of the investigation was to determine the most functionally grounded level of the formation of colonic reservoir from the margin of the anal canal while performing a low anterior resection of the rectum. Sphincter-preserving operations were performed in 113 patient with the formation of colonic reservoir and direct stepler colorectal anastomosis. Questionnaires and apparatus "Colodynamic-3" were used to follow-up 28 patients with the reservoir (main group) and 19 patients with a direct anastomosis on whom the operations had been made more than a year ago. The rate of the development of complications was almost the same in the both groups--28.5% and 26% correspondingly. The reservoir-accumulating function became less in the group of "direct" anastomoses. The best parameters of the reservoir-accumulating and evacuatory ability of the colonic reservoir were found to be in patients with the level of anastomoses 4-6 cm from the anal canal margin. Creation of the reservoir was more difficult in patients with the carneus mesentery and a small width of the sigmoid colon.

[Prospects for saving vegetative nerves during operations for cancer of the lower rectum].

The aim of the work was to investigate the possibility to isolate and preserve the vegetative nerve of the pelvis in operations for low rectal cancer. In preparation of 17 corpses of people dead from causes not associated with a pathology of pelvic organs, mainly two forms of the structure of the superior hypogastric plexus were isolated--with many branches and with few branches. The pelvic promontory is taken as a reference-point. Frontal resection and extirpation of the rectum were fulfilled in 17 patients with low rectal cancer using the nerve-preserving technique of operation. Saving the vegetative nerves of the pelvis does not result in greater number of postoperative complications and positively influences the genitourinary function of the patients.

[Selective surgical cholangiography].

Based on an analysis of data of ultrasonic examinations, cholangiography and operative findings, the authors consider that intraoperative cholangiography is necessary but in 48% of patients. The article gives grounds for indications to intraoperative cholangiography.
