The etiology of primary volvulus of the omentum in the absence of other intraabdominal pathology remains obscure. Abdominal pain and tenderness are always present. Computed tomography demonstrates an abdominal mass composed of fatty and fibrous folds. Characteristic for a torsion is the concentric distribution of the fibrous folds at the site of torsion.

Valvular colonic sphincter substitutes. An experimental study in dogs.

Three types of colonic sphincter substitutes were placed at an abdominal colostomy in dogs. Simple valve construction (8) was based on orthograde intussusception of the colon over 3.5 cm. In calibrated valves (6) the intraluminal pressure was increased by reducing the diameter of the overlying muscle coat. Reverse smooth muscle plasties (5) and simple colostomies (5) served as controls. Immediately after construction highest pressure (50 +/- 8.9 mm Hg) was obtained in calibrated valves. After 1 month the pressure dropped to 20 mm Hg, but remained stable thereafter. Although valvular constructions cannot maintain high pressure, they may be useful as substitutes for the internal anal sphincter by filling up the lumen so that the action of a surrounding striated muscle ring becomes more effective.

The management of abdominal wall stomata: skin protection, peristomal wound healing and support for the collecting bag. A multi-center study.

The specific properties of Stomahesive tested in 116 stomal and 20 fistulous patients render it really useful in stomatherapy where it increases the comfort of the patients: 1. it offers an excellent peristomal skin protection whatever the nature of the stoma or origin of the fistula; 2. it promotes rapid healing of skin lesions, even in ileostomy, transverse colostomy, ureterostomy and fistula patients; 3. it ensures an effective degree of impermeability; 4. it provides a large base for adhesion of the collecting bag; 5. it can be kept on for about 6 days in most cases; 6. The local tolerance is excellent (Acta chir. belg., 1977, 76, 533-537).

Planned relaparotomies for advanced, established peritonitis from colonic origin.

Patients presenting diffuse, advanced, established peritonitis due to free perforation of the colon, in whom an adequate abdominal debridement cannot be obtained in one operative session were selected. We report results of the planned relaparotomy approach in 44 patients as compared with an historical series of 9 analogous patients treated by on demand exploratory relaparotomies. Planned relaparotomies were performed every 2 days until the abdominal cavity became macroscopically clean. This approach significantly reduced both the incidence of multiple organ failure and the mortality rate (31%) as compared with the regimen of on demand relaparotomy. The mortality rate in the planned relaparotomy group is related to the age of the patient and to the nature of peritonitis. Faecal peritonitis carries a higher mortality rate than purulent peritonitis. The mortality rates of severe postoperative peritonitis and advanced primary peritonitis were not significantly different. Surgery for severe, diffuse peritonitis has to be prompt, moderately aggressive and repeated if necessary. Therefore, planned relaparotomies have a place in the treatment of selected patients presenting diffuse, advanced, established peritonitis.

Recurrences after highly selective vagotomy in refractory and non-refractory duodenal ulcer disease.

The recurrence rate after highly selective vagotomy was evaluated in patients with chronic duodenal ulcer disease presenting non-refractory (64 cases) or refractory ulcers (41 cases) followed for 1 to 8 years postoperatively. Refractoriness was considered when an ulcer remained symptomatic and was not healed at endoscopy after 8 weeks (3 cases) or 12 weeks (30 cases) of appropriate treatment with cimetidine, or when it recurred during maintenance therapy and did not heal after adapted treatment (8 cases). The cumulative 5 year-recurrence rate was 28.7% in refractory ulcers, in contrast with 9.3% in non-refractory ulcers (p less than 0.05). The early and constantly increased risk of recurrences in the refractory ulcer group could not be explained by factors related to surgeon or technique, nor by differing patient characteristics, including sex, age at the first ulcer episode, duration of the preoperative ulcer disease, familial ulcer history, prior ulcer complications, use or abuse of anti-inflammatory drugs, caffeine or alcohol, smoking habits and occupational state. It is concluded that highly selective vagotomy can not be considered a surgical procedure of choice in patients with refractory duodenal ulcers as there are valuable alternatives.

[Treatment of intestinal atresia].

Thirteen cases of intestinal atresia are described: 9 jejunal and 4 ileal. The duration of pregnancy was significantly shorter and the birthweight significantly lower in jejunal than in ileal atresia. The proximal intestine was strongly dilated in 8/9 cases with jejunal atresia. This group also contains several complex and extended varieties of atresia. The postoperative mortality was 8%. Gastrointestinal functional disturbances occurred only in the group treated for jejunal atresia. These disturbances were temporary and occurred postoperatively in 2 cases but reoperation was mandatory in another 2 cases, once without functional success. There were no problems in the other cases. Ileal atresia is easy to treat and the result is always good. In contrast, the situation is much more challenging in cases of jejunal atresia: prematurity, higher incidence of complex and extended gastrointestinal malformations, impossibility to resect the dilated proximal segment, presence of a long under-developed distal segment. No problems have been observed after construction of a double stoma and restoration of the intestinal continuity. However a proximal stoma leads to important fluid and electrolyte losses, necessitating total parenteral nutrition. Functional gastrointestinal disturbances are frequently observed after end-to-side anastomosis in Y with mucous fistula. An end-to-end anastomosis can be combined with enteroplasty of the proximal distended bowel segment, eventually including the duodenum. Although the enteroplasty technique is an important progress in the treatment of neonates with extended types of jejunal atresia, transit problems cannot always be prevented by this procedure.

[Aglossia-adactylia with jejunal atresia].

Case report of a newborn with the aglossy-adactyly syndrome associated with complete jejunal atresia. Review of the literature does not allow any conclusion concerning the etiology of the observed malformations. The jejunal atresia, present in this case is probably coincidental. Attention is drawn on the possibility of prenatal diagnosis of obstruction of the digestive tract by ultrasound whenever pregnancy is complicated by hydramnios.
