[Hemorrhagic gastroduodenal ulcer: when is it necessary to operate?].

In the context of severe haemorrhage from peptic ulcers, surgery remains the safest method of haemostasis, but at the cost of a relatively high mortality. The time of surgery constitutes one of the prognostic factors. It has been demonstrated that the mortality increases significantly with the delay in operation and recurrent haemorrhages; it is therefore important to operate rapidly on patients at risk of recurrence and therefore to determine the clinical and endoscopic criteria capable of predicting this recurrence.

[The role of surgery in the treatment of duodenal ulcer].

If duodenal ulcer surgery has been limited since introduction of anti-H2, it keeps an important position. For chronic duodenal ulcer, surgery currently represent a reasonable alternative to medical treatment, owing to two operations, fundic vagotomy and more recently anterior lesser curve sero-myotomy + posterior truncal vagotomy; the permanent effect of surgery contrast with the only suspensive effect of medical treatment on ulcer disease. For ulcer complications, surgery is often mandatory, but in emergency, truncal vagotomy + drainage keeps a predominant position.

[Transpleurodiaphragmatic drainage of post-operative sub-phrenic abcesses (author's transl)].

About 19 observations, authors analyse a method for treating post-operative sub-phrenic abscesses: transpleurodiaphragmatic drainage. This study is showing the efficiency of the technic which is a real flattening of the abscess. It is showing as well its inocuosness as mortality and morbidity are none in spite of the field this treatment is used on. On the other hand this method prescribes very definite conditions: the real sub-phrenic abscess must be single and quite localized in postero-lateral position.

[Acute calculous cholecystitis (author's transl)].

The authors studied 333 acute cholecystitis out of 2,200 operated on for lithiasis of the gall-bladder, 186 bacteriological tests were carried out on the vesicular liquid and wall. They insist on the main anatomo-pathological characteristic: early, partial or total destruction of the mucous together with acute inflammatory lesions of the wall and even sometimes necrosis. This irreversible lesion is due to the acute obstruction of the gall-bladder by blockage of a calculus. Acute cholecystitis are practically always aseptic at the beginning. Sepsis is a secondary complication. These anatomo-pathological and bacteriological elements have two therapeutic corollaries: 1. The patient has to be operated very early at the aseptic stage. 2. Preliminary antibiotherapy becomes useless. Under these conditions there is practically no death before the age of 65. Mortality concern old people, operated late and suffering from other disease.

[Results of a series of 100 highly selective vagotomies for duodenal ulcer (follow up of 6 months to 5 years) (author's transl)].

The authors analyse a series of 100 highly selective vagotomies for duodenal ulcer; 92 operated patients were followed up for 6 months to 5 years. The mortality was nil, the digestive sequelae were rare or mild. The recurrence rate was 4.4 p. cent and the proportion of good or very good results according to Visick's classification was 87 p. cent. The authors emphasise the necessity for broad dissection of the cardia for complete vagotomy.
