The authors report the presentation of a rare small bowel mesenchymoma at the jejuno-ileal transition found during the operation of an adenocarcinoma of the recto-sigmoid junction. They discuss the pathology and clinic of the benign mesenchymal tumors of the small intestine.
The authors report about the elimination of foreign bodies fixed in the oesophagus and aspirated into the right main bronchus. They discuss the diagnostic work and the ways of its elimination. They emphasize the importance of cooperation between the endoscopist and the surgeon.
The authors examined one of the characteristic complications--dysphagia--of proximal selective vagotomy widely applied in the surgical treatment of duodenal ulcerations. To gain a better knowledge of the causes of this type of complications measuring the pH value for 24 hours and manometric examinations of the lower esophageal sphincter were performed in 12 patients without complaints following operation and in 22 with the complaint of dysphagia. No significant changes were observed between the two groups either in basal sphincter pressure or in the two parameters characteristic for reflux activity, e.g. the number of reflux episodes and reflux index. Operation resulted in a slight increase of the basal pressure and the decrease of reflux activity in both groups. It is likely that postvagotomical dysphagia has a multifactorial background: denervation or mechanical trauma of the lower oesophagus and the uncoordinated and insufficient relaxation of the lower oesophageal sphincter following swallowing.

The frequency and severity of the post-vagotomic dumping syndrome and diarrhoea were studied in 470 cases. After vagotomy the incidence of the dumping syndrome is lower and that of diarrhoea higher than after conventional gastric resection. The dumping syndrome occurred in 8.30 percent [39 cases], but only three patients belonged into the severe group [0.80 percent]. The frequency of post-vagotomy diarrhoea was 11.49 percent [54 cases] of which six belonged into the severe group [1.34 and 1.04 percent, respectively]. The possibility respectively of preventing or reducing the frequency of these side-effects is discussed.

426 subdiaphragmatic vagotomy operations were performed by the authors. On basis of the results obtained they give full details of the complications arising in the course and in the early postoperative period after vagotomy, and also of the possibilities preventing these complications. They call the attention to the more frequent injuries of the spleen and the oesophagus, and to the increasing number of the subphrenic abscess. Finally, they emphasize the low mortality rate of the vagotomy in comparison to the traditional gastric resections.
