[Motor function of the gastrointestinal tract after extensive resection of the small intestine]

A functional and roentgenological investigation of the motor-evacuative function of the digestive tract has shown that resection of the small intestine with construction of an entero-enteroanastomosis is followed by a delayed passage of a contrast suspension in the remained portions of the small intestine. Further, there occurs a delay in evacuation of the contrast food suspension from the stomach in marked hypermotor dyskinesia of the small and large bowel. Following resection of the small intestine with an ileo-transverse anastomosis hypermotor peristalsis was observed. The passage of chymus from the small intestine into the colon lasted 1--2 hours. The cecal portion of the colon at the site of ileo-traansverse anastomosis was enlarged sacwise and turned into a reservoir for permanent stasis of the bowel content. The ileocecal portion regulating the chymus income into the colon plays a decisive role in intensity of compensatory-adaptive processes following resection of the small intestine.
