Surgical attitude towards carcinoid tumour of the appendix. Review of the literature.

Carcinoid tumours of the gastrointestinal tract are most frequently located at the appendix. We report two cases: In the first case, we realized a simple appendicectomy. In the second case, two weeks after the appendicectomy was performed, according to the histological characteristics of the tumoral specimen, the patient underwent a laparoscopic right hemicolectomy with regional lymphadenectomy. In both cases, 5-HIAA (5 HydroxyIndolAceticAcid) is assayed regularly and remains normal.

Cranio-facial and humeral melorrheostosis.

First described by LERY and JOANNY in 1992, melorrheostosis is an uncommon linear hyperostosis of unknown aetiology, which may be associated with soft tissures changes. Although all bones may be affected, cranio-facial involvement is very rare. Only six such cases have been found in the literature. This report describes a case of cranio-facial and left humeral melorrheostosis with symptomatic radial nerve involvement. Resection of the melorrheostotic bone was performed because of involvement of the radial nerve.

Mucinous cystadenocarcinoma of the appendix. A rare tumour of the right iliac fossa.

A case of mucinous cystadenocarcinoma of the appendix is presented. The clinical feature is a painful syndrome of the right iliac fossa. In our observation, the diagnosis was not allowed by preoperative imaging. Appendectomy was initially performed and completed by right hemicolectomy and lymphadenectomy after histological diagnosis of the appendicular malignant tumour was forwarded. The prognosis of this tumour is generally excellent providing early diagnosis and wide enough surgery.

Laparoscopic repair of perforated duodenal ulcer. A prospective multicenter clinical trial.

BACKGROUND: A series of 100 consecutive patients with perforated peptic ulcer were prospectively evaluated in a multicenter study. The feasibility of the laparoscopic repair was evaluated. METHODS: All patients had peritonitis, 20% were in septic shock, and 57% had delayed perforation. Conversion to laparotomy was necessary in eight patients. The morbidity rate was 9% and mortality rate 5%. RESULTS: The mean delay of postoperative gastric aspiration (mean 3.4 days) and resumed food intake (mean 4.4 days) as well as the mean postoperative hospital stay (mean 9.3 days) were comparable to conventional surgery, but postoperative comfort was subjectively increased by laparoscopy and noticed by all laparoscopic surgeons participating in this study. CONCLUSIONS: Laparoscopic repair of perforated peptic ulcer proves to be technically feasable and carries an acceptable morbidity and mortality rate, compared with conventional surgery.

Effect of jejunal resection on the gastric acid secretory response to pentagastrin, histamine and feeding in dogs.

In dogs with gastric fistulas and denervated pouches from the oxyntic area, the acid secretory responses to a meal and to graded doses of histamine and pentagastrin were measured before and after resection of the upper half of the small bowel. Intestinal resection caused a small but significant increase in submaximal and maximal response from the pouch to histamine and pentagastrin without modification of the ED50. This effect was not observed in the innervated stomach. The response from the pouch to feeding was markedly increased and prolonged. These data indicate that both an increase in stimulation and an increase of the response to this stimulation are responsible for the increased acid secretion observed in the pouch when resected dogs were fed. These effects could be explained by the withdrawal of inhibitors of intestinal origin.

[Effect of cortisone acetate on acid secretion induced by histamine, pentagastrin, gastrin and food in dogs].

The effects of long term treatment with cortisone on the gastric secretion induced by histamine, pentagastrin, porcine gastrin and a meal have been investigated in four dogs with both gastric fistula and Heidenhain pouch. Cortisone increased the postcibal acid output and the observed maximal acid response from the pouch to all three exogenous stimuli. The ED 50'S remained unchanged. The same effects although less marked were observed in the innervated stomach. These data indicate that the increased acid secretion observed after long term treatment with cortisone is largely due to an increased secretory capacity of the gastric mucosa. This latter could result from an increase in the number of secretory units or to partial removal of a non competitive inhibitor of gastric secretion.

Effect of feeding on catabolism and activity of exogenous gastrin in dogs.

The effect of meal upon the catabolism and activity of exogenous gastrin was tested in 4 antrectomized and 4 non antrectomized dogs with Heidenhain pouches. In both antrectomized and non antrectomized dogs infused with exogenous gastrin, the meal decreased the serum gastrin level. This decrease amounted to about 20%, 60 minutes after feeding and the gastrinemia then returned gradually to control levels. In non antrectomized dogs, infusion of a near maximal dose of gastrin increased the acid response to the meal to a level above the maximal histamine acid output. Exogenous gastrin also increased the acid response to a meal in antrectomized dogs. These data indicate: 1) That feeding increases the metabolic clearance rate of exogenous gastrin. This effect could be at least partly related to changes in the intestinal blood flow. 2) That, after feeding, one or several hormones capable of stimulating the acid secretion but unrelated to gastrin are probably released. These hormones could be of major importance in the response of denervated pouches to feeding.
