The Authors report two cases of cysto-hepatic ducts. Clinical and therapeutic patterns of this rare biliary disease are stressed, underlining the surgical hazard related to iatrogenic damage of bile ducts during operative manoeuvres.

Even if it is a rare disease, acute cecal diverticulitis is a diagnostic and therapeutic challenge for the surgeon. The authors present their experience synthetically and compare their results with the literature. Their experience is not very different from the results reported by many other authors. Five cases underwent radical treatment (right colectomy) and 6 cases were treated with a more conservative operation (diverticulectomy and/or invagination). Only one patient was treated medically. Acute diverticulitis of the cecum requires the solution of three difficult questions: 1) preoperative diagnosis; 2) intraoperative diagnosis; 3) correct therapeutic procedure.

Gallbladder cancer is the fifth of the digestive neoplasms. Diagnosis is often made very late sk that prognosis is really poor. We present 84 patients operated on for gallbladder cancer and 1 for carcinoid. Sixty-eight of them had a complete follow-up.

The study included 20 patients affected by cholelithiasis and choledocholithiasis. Al patients underwent cholecystectomy; after choledochotomy, choledochal stones were removed using a Fogarty's biliary catheter (no. 5) and, subsequently, the papilla was calibrated by inserting the end balloon of the catheter, which and been filled with 0.3 cc of water, beyond the level of the papilla itself. The catheter was then withdrawn. No T-tubes were left in the common bile duct in any patient, no post-operative complications were observed and all patients were dismissed within seven days.

A case of gallbladder torsion complicated by sigmoid volvulus and sub-torsion of the ileus is reported because of the difficulty of diagnosis, conditioned by polymorphic symptomatology, the expression of a variety of causes and contributing causes that play an important role in the greater or less onset of dramatic symptomatology, and because of the rarity of the pathology.

A particular case of Meckel's diverticulum, with phlegmonous appendicitis and mesenteric cyst associated, is presented. The Authors discuss the etiophatology, explaining the anatomic and clinical found situation.

Various techniques are used for the anatomo-functional study of bilio-digestive anastomoses on jejunal loop autonomized according to Roux. Here a transparietojejunal endoscopic investigation is proposed that permits direct sight of the anastomosis, biliary sampling for cultural examination and dilatative type therapeutic manoeuvres, biopsies or extractions of residual stones from the bile ways that would not otherwise be possible without further surgery. A clinical case is reported.

Two cases of pseudo-obstruction of the colon (Ogilvie's syndrome) are presented. Increasing abdominal distension and the pain suggested surgical treatment for both patients. The operation showed in the first case a marked dilatation of the transverse colon and sigmoid, in the second the dilatation of the ascending and transverse colon, without any distal obstruction. Enterotomy was performed only in the first case, as the diameter of the colon was more then 10 cm. The authors, by review of the literature and their own experience, propose a critical revision of the syndrome, discussing the physiopathology of the rising disease.

A case of pancreatitis that preceded and complicated, in the postoperative phase, one of ileal volvulus imprisoned in the Douglas and operated two days after admittance is reported. Clinical and laboratory data only permit hypotheses and this uncommon case of associated pathology is reported so that the situation can be borne in mind in the practical solution of surgical emergency.
