[The pneumodynamic barium x-ray study of small intestine adhesions (a preliminary report)].

Small-intestinal adhesions are not very rare, but on conventional X-ray examination are frequently missed because of their poor semiotics. By the method of pneumodynamic-barium X-ray examination, which allows to obtain high-quality double-contrast image, in addition to the better visualized classical symptoms--exostotic rebounds, diverticulum-like deformities, peristaltic spasms, spastic contractions etc, one may evince also the following new criteria: when inflated the intestines do not freely increase their volume, as is normal, are not unplaited along the entire abdomen, but remain amassed in a definite zone (usually in the left half); On external pressure the inflated loops do not move, as do the ones without adhesions, but remain fixed, so that their structure remains unchanged. The intestinal loops are crooked with acute angles; when in a normally inflated state, they are not crooked, but long. A frequent finding in small intestinal adhesions are the V-shaped figures in whose bottom there is barium meal over which air passes. A study of the small-intestinal cannon contraction reveals insufficiency in the hydrodynamics of the intestinal passage, marked by delayed evacuation, in spite of the strong peristalsis. This method allows a more precise elucidation than the conventional X-ray examination of the abdominal status in small-intestinal adhesions and better orientates the surgeon to choose conservative or operative treatment.

[Peritoneovenous shunt in ascites].

For a two-year period (1987-1988) 14 peritoneal-venous shunts with Le Veen's valve were performed in patients with cirrhosis of the liver and ascites. Immediate effect, manifested by decrease in the abdominal circumference and diminution or even complete disappearance of ascites with increased diuresis, was observed in 12 patients. Two patients died during the early postoperative period. The indications, postoperative preparation, operative technique, complications and postoperative care in this type of operative intervention are discussed. Inference is made that the good postoperative results depend on the need patients with refractory ascites to report early enough for operative treatment.

[One-step breast reconstruction].

The mental trauma induced by removal of the mammary gland for cancer may be overcome by reconstruction of the breast. One-step reconstruction applied on 4 patients showed considerable advantages over a postponed reconstruction: technically it is easier to perform; a single stay of the patient in hospital makes it cheaper. It is no obstacle to perform pre- and postoperative radio- and chemotherapy. According to available data in the literature, implanted prosthesis or transposed flap do not veil a local relapse.

[Rectal prolapse].

A variety of pathogenetic mechanisms underly rectal prolapse. Treatment is predominantly operative. Some of the basic surgical techniques are reviewed. The modification of posterior rectopexy with ampoxen, implicated at the Department of Surgery of the Medical Academy in Sofia, is presented. After exposure of the rectum at the side of the sacrum, the intestine is fixed to the presacral fascia. The aim is to create adhesions. Septic complications are avoided, which otherwise, with applications of other synthetic implants are quite common. Experience is recorded with the application of the method in three patients, who were followed up over a period of 2 years.

[A case of somatostatinoma of the pancreas].

A case of a 36-year-old man with pancreatic somatostatinoma is reported. Such cases are very rare. The following signs were found; quick ESR, increased alpha 2- and beta-globulins, shortened Weltmann's coagulation band, increased serum bilirubin level, especially of the conjugated fraction, enzyme constellation of cholestasis and moderate liver cytolysis. Ultrasound examination of the abdomen, retrograde cholangiopancreatography and percutaneous liver cholangiography were performed in order to prove the diagnosis. They demonstrated an obstruction in Vater's papilla region and a bulky process in the head of the pancreas. The patient was operated. The microscopic, electron microscopic and immunohistochemical examinations proved a somatostatinoma of the pancreas. The positive immunohistochemical tests for somatostatin and carcinoembryonal antigen in the tumor cels are especially indicative.
