The experience with operative treatment of 974 patients with chronic paraproctitis has been summarized. After the operations for intrasphincter fistula, 1% of the patients developed a disease recurrence, 0.5%--incompetence of the anal sphincter; for transsphincteric fistula--2.6 and 1.9%, respectively, for extrasphincteric fistula--5.7 and 5.2%. A fistula excision into the intestinal lumen is an operation of choice in intra- and transsphincteric fistula. In extrasphincteric fistula, fistula excision, plastic transfer of mucosa for closure of its internal opening with preservation of the anal sphincter should be performed. In presence of the extensive scars and purulent leaks, a ligature should be added to fistula excision.

The results of operative treatment of hemorrhoids in 1437 patients are presented. After hemorrhoidectomy with restoration of the rectal mucosa, the decrease in incidence of complications after operation was noted.
