Bladder augmentation with detubularized intestinal segment.

The authors report on 9 cases of bladder augmentation with detubularized intestinal segments. The capacity of the contracted bladder was increased in 4 cases; care was taken to prevent the development of an hour-glass bladder. In a young female patient a caecal-ileal segment was applied so that in case of a possible future pregnancy the mesentery should not hinder the growth of the uterus.

[Laparoscopic cholecystectomy].

Traditional cholecystectomy has been the standard surgical treatment of the gallstone disease for more than 100 years. The technical development led to a new surgical procedure and its rapid acceptance. This is laparoscopic cholecystectomy.

[Prevention of carcinoid tumor crisis].

A case of the carcinoid tumour of ileum causing hormone producing multiple hepatic metastases was described. Sometimes after feeding and drinking of beer the "flush" and the diarrhoea appeared. Multiple hepatic metastases were established by ultrasound.

Technique of extensive proximal selective vagotomy.

Based on the experience of 727 operations, the technique of proximal selective vagotomy used by the authors is reviewed in stages. They consider pyloroplasty justified to perform only in complicated cases (bleeding, perforation, stenosis) for preventing complications. Based on their results (mortality rate: 0.

Incidence of cholelithiasis after truncal and selective vagotomy.

In order to establish the incidence of cholelithiasis after vagotomy, the patients operated upon in the period January 1st 1966, to December 31st 1971, were reexamined. The incidence of cholelithiasis was 12% after truncal and 2.4% after selective vagotomy, thus complications involving the gall bladder are more frequent after truncal than after selective vagotomy.

Action of caerulein, glucagon or prostaglandin E1 on the motility of intestinal villi.

If injected into the artery supplying the first jejunal loop of dogs, caerulein increases, glucagon and PGE-1 decrease villous motility significantly. The relationship between the natural logarithm of the drug doses and their effects is linear.

Effect of truncal vagotomy on the bacterial flora in the duodenal juice on dogs.

The qualitative and quantitative changes in the bacterial flora of the duodenal juice after truncal vagotomy have been studied in self-control experiments in dogs. The intervention was followed by a rise in the bacterial count without a change in qualitative composition. It is suggested that the accumulation of microorganisms might contribute to the development of postoperative diarrhoea.

[Electron microscopic changes of the intestinal mucosa following truncal vagotomy].

Ultrastructural changes on the mucosa of the jejunum and ileum after truncal vagotomy were studied in the dog. Tests performed 2, 3, 7 and 10 days, 2, 4, 5, 6, 7, 8 and 9 weeks as well as 4, 5, 6, 9 and 12 months after vagotomy showed no significant changes in the epithelial cells. The microvilli, smooth and rough surface endoplasmic reticulum, the free iebosomes and the terminal web area were completely intact.
