Volvulus of the colon.

The results of treatment for volvulus of the colon during 13 years in a community hospital are analysed, It is concluded that sigmoid volvulus should be treated with proctoscopic examination and insertion of a rectal tube, unless signs of gangreana or peritonitis are present. In patients without accompanying sever diseases, elective resection should be performed later. Repeated tube decompressions should be attempted in patients with recurrence and high operative risk. Unsuccessful tube decompressions or signs of a non-viable colon should be followed by emergence laparotomy and, probably, resection of the sigmoid colon whether gangraena is present or not. Volvulus of the cecum should be treated with operative reduction and pexia or cecostomy, unless gangreana necessitating a hemicolectomy is present.

Clinical results 6 to 8 years after truncal vagotomy and drainage for duodenal ulcer in 500 patients.

The clinical results of truncal vagotomy and drainage for duodenal ulcer in 500 patients are evaluated by a personal 6-8 year follow up. Pyloroplasty was used unless pyloric stenosis made a gastrojejunostomy necessary. Forty-three patients had recurrence (39 were reoperated) and gastric ulcer was seen in five. The rate of dumping was 24% (severe in 3%) and rate of daily-monthly diarrhoea 40% (severe in 8%). Neither dumping nor diarrhoea was related to histamine-activated gastric acid secretion ten days after vagotomy and insulin-activated acid secretion 3 to 4 years later. Dumping was related to epigastric fullness and diarrhoea. Recurrence was related to histamine-activated secretion before and 10 days after vagotomy and to insulin-activated secretion 10 days and 3-4 days after vagotomy. Minor changes were seen in weight- and laboratory-measurements. Anemia was not related to prophylactic intake of iron. Satisfactory results (Visick I-III) were seen in 80% of the patients. The figure may be increased to 86%, including results of operations for recurrence, gastric ulcer and other diseases occurring after the original vagotomy and drainage; even then, the results seem less satisfactory than those after other operations for duodenal ulcer.

Gastric acid secretion and risk of recurrence of duodenal ulcer within six to eight years after truncal vagotomy and drainage.

The value of insulin and augmented histamine tests in predicting recurrence of duodenal ulcer within six to eight years after truncal vagotomy and drainage was assessed in a series of 500 consecutively and electively operated patients. Criteria of recurrence were established by a discriminative analysis of gastric acid secretion parameters. Recurrence was predicted with a probability of about 75% in patients with dyspepsia, the proportion between recurrences and dyspeptic nonrecurrences being 1:1. The discriminatory ability of the insulin test was no better than that of the postoperative histamine test. Men with a preoperative PAO > 46.1 m-equiv/h had a risk of recurrence of 21%, women with a PAO > 41.5 m-equiv/h, 28%. Below these levels the risk was 5 and 1% respectively, demonstrating that recurrence after vagotomy is related to the number of parietal cells before vagotomy. A rationale is provided for antrectomy and vagotomy in duodenal ulcer patients with a high number of parietal cells.
