[Biliary ileus caused by incarceration of a large gallbladder calculus in the duodenal bulb in a young man]. / Ileo biliare da incarceramento di grosso calcolo colecistico nel bulbo duodenale in un giovane uomo.

A case of gallstone ileus is presented, secondary to a biliary-enteric fistula with obstruction of the duodenal bulb, in a 23 year-old man. The patient underwent exploratory laparotomy because his clinical condition was deteriorating steadily. An intraoperative diagnosis of gallstone ileus was formulated; a cholecystectomy and a suture of the duodenal opening were carried out.

Presence of duodenopancreatic feedback in minipigs and possible interference from the bile.

In two minipigs chronic pancreatic and duodenal fistulas, which allowed the diversion and the intestinal replacement of pancreatic secretion, were prepared. In a third minipig a chronic biliary fistula was also prepared so the bile secretion could be fed back into the intestine through a duodenal catheter. In these animals a chronic gastric fistula was made so gastric secretion could also be collected. Diversion-replacement of pure pancreatic juice and of bile were carried out in the fasting state. This study confirms the presence of a feedback regulatory mechanism in exocrine pancreatic secretion in the pig. Moreover, it suggests that bile can interfere with this phenomenon.

[Pseudocystic pleural fistula documented by retrograde cholangiopancreatography]. / Fistola pseudocisto-pleurica documentata mediante colangiopancreatografia retrograda.

The use of recently introduced methods such as computerised axial tomography (CAT), in addition to endoscopic retrograde cholangiopancreatography (ERCP), has in recent years led to attainment of new targets in the diagnosis of pancreatic diseases. The Authors present a clinical case of massive and recurring left pleural effusion in a patient with a pseudocyst at the level of the cauda pancreatis. They report the clinico-diagnostico-instrumental factors leading to pre-operative diagnosis of pseudocystic-pleural fistula.

[Modification of an experimental model of chronic pancreatic and biliary fistula in the minipig (author's transl)]. / Modifiche di un modello sperimentale di fistola pancreatica e biliare cronica nel minipig.

An improvement in Corring's experimental model in the minipig is described. The model requires: -- a complete diversion of the biliopancreatic secretion and the possibility of its reintroduction into the duodenum; -- a particular anaesthesiological, technical and management problems taken up during the course of the research. Data are also given about basal pancreatic and biliary secretions in this particular experimental model.

[A case of choleretroperitoneum (clinical study)]. / Su un caso di coleretroperitoneo.

The AA. report one case of "choleretroperitoneum". They discuss the techniques of diagnosis that they have used, outlining the importance of A.C.T. (Axial Computerizing Tomography) and of Transduodenoscopic Cliolangiography, that have permitted a preoperative diagnosis and an exact surgical treatment of this case.
