[Nerve-preserving operations in surgery of rectal cancer].

Forty-eight patients underwent surgery for rectal cancer. In all the patients total mesorectumectomy was combined with one of the types of nerves-preserving surgeries. Three groups were divided depending on types of this surgery: 1-- complete preservation of elements of autonomic nervous system (n=31), 2 -- partial preservation (n=16), 3 -- complete ablation (n=1). In 30 patients of group 1 normal urination recovered on postoperative day 2 to 4. In 2 patients of group 2 stable atony of urinary bladder was seen, and in 2 patients -- reflex ischuria. In patient of group 3 normal urination recovered on day 14 after surgery without vesical tenesmus. Long-term results were assessed in 1 to 12 months. No recurrences occurred. It is concluded that nerve-preserving surgeries improve functional results without loss of oncological radicalism.

[Long-term results of excision of anal fissure in combination with lateral subcutaneous sphincterotomy].

One hundred and seventeen patients with anal fissure underwent fissure excision in combination with lateral subcutaneous sphincterotomy. The mean follow-up after treatment was 4.3 years. All the patients were questioned by the phone. Thirty-six ones who had some symptoms were examined at outpatient department. The examination included physical examination, anorectal manometry, endorectal ultrasonography, irrigoscopy, defecography. Recurrences of anal fissure were revealed in 12 (10.2%) patients. The cause of recurrence was incomplete sphincterotomy. Different grade of anal incontinence was revealed in 23 patients: 2 of them had soiling, 12 -- incontinence of the flatus, 8 -- incontinence of liquid faeces, 1 -- incontinence of solid faeces. In 4 patients the cause of anal incontinence was excessive sphincter section during sphincterotomy, in 16 -- perineal descent syndrome, in 3 -- advanced age. It is concluded that it is necessary to modify surgical technique and to examine patients more carefully before surgery including anorectal manometry.

[Long-term results of formation of smooth muscle sphincter in the perineal colostomy area in patients after rectal extirpation].

The authors discuss an original method for formation of a smooth-muscle cuff from the wall of a pulled-through colon in the region of a perineal colostoma. It was applied in 89 patients who had undergone extirpation of the rectum for malignant neoplasms. The smooth-muscle sphincter was formed during removal of the rectum in 72 patients and no earlier than 2 years after the extirpation in 17 patients. Inflammatory complications developed in the region of the perineal colostoa in the early postoperative period in 13.5% of cases. They were due to necrosis of the distal part of the pulled-through intestine in 3.4% of cases. There were no fatal outcomes. The late-term results were studied in follow-up periods of up to 7.5 years. Satisfactory functional results were produced in 83% of the patients. Physiological examination showed the presence of a functioning sphincter in the region of the perineal colostoma.

[Comparative evaluation of the anal sphincter function after sphincter-sparing operations in diffuse polyposis].

Experience in treating 76 patients who were subjected to various sphincter-preserving operations is analysed. It is shown that after subtotal resection of the large intestine with ++abdomino-anal resection of the rectum and pull-through of the right parts of the colon into the anal canal as well as after pull-through of the segment of the transverse colon into the anal canal, the neuro-reflex activity of the musculus sphincter ani internus is destroyed in 55% and reduces in 25% of patients while the reflex activity of the musculus sphincter ani externus is disturbed in 45% of patients and is not restored later. The results bear evidence that the condition of the rectal obturation apparatus does not depend on the segment of the colon subjected to the pull-through operation (cecum, ascending colon, transverse colon). Experience has shown that the results of sphicterometry, electromyography, and electromanometry in various periods after colectomy, mucosectomy of the rectum, and formation of ileorectal anastomosis are much better than those after pull-through operations on various parts of the colon, and return to normal values in 18 months.

[Functional state of the distal part of the large intestine in Crohn disease].

State of the locking apparatus has been studied in 22 patients with Crohn's disease free of the anorectal complications. Even prior to the development of these complications caused by metabolic abnormalities and inflammatory changes in the intestinal wall the locking apparatus undergoes certain functional changes.
