[Y Roux anastomosis of small intestine in gastrectomy and esophagectomy]
Abstract:
A clutch-like method of esophagojejunal anastomosis on the excluded by the Roux method loop of the small intestine was worked out in experiments on 80 corpses of humans. It was found that the anastomosis should be made at a distance of 3.2 +/- 0.48 cm (two diameters of the patient's esophagus) from the tightly sutured part of the small intestine. In the clinic there were no cases of incompetence of the anastomosis sutures in 86 gastric cancer patients aged from 31 to 71 years (81 gastrectomies and 5 extirpations of the gastric stump). Two patients died (2.3%). The follow-up of the patients during 1-10 years after operation has found that mild reflux-esophagitis developed in 6.1% of the patients, average degree--in 2.04%. No cicatricial strictures of the anastomosis were revealed. The method was used in 6 patients in gastroplasty after Kupriyanov-Zakharov. The dumping syndrome of mild degree developed in 23.6%, average--in 2.7% of the patients. The anastomosis can be used in gastrectomy as a method of choice in extirpation of the gastric stump.
