Routine use of local anaesthesia associated with tension-free hernioplasty in surgical treatment of inguinal hernia allows an immediate patient walking and prompt discharge from the hospital unit: with this technique 89 cases in two years were operated. The anaesthesia-related discomforts and complications are minimal. The addition of an intravenous sedative (propofol) premis to extend this approach to anxious patients too.

Malignant fibrous histiocytoma is a pleomorphic soft tissues sarcoma usually found in the extremity and in the retroperitoneum. The primary intra-abdominal localization of this tumour is very rare and only thirty-five previous reports are present in the world medical literature. The Authors report a case of giant malignant fibrous histiocytoma of the mesentery, which is treated by surgical removal plus adjuvant chemotherapy.

Lipoma of the large intestine is a rare, benign tumor. The clinical findings and the diagnostic studies are analysed and a case of giant submucosal colonic lipoma removed by colonoscopy is reported. Colonoscopic removal of submucosal lipomas is recommended, while the necessity of a surgical treatment in presence of intussusception or subserosal lipomas is confirmed.

The paper gives a short critical bibliographic review of colonic preparation for endoscopy, focusing on the out-patient use of gastrointestinal endoscopy. A method of preparation based on dietary restrictions plus cathartics is proposed that allows the number of enemas used to be reduced to a minimum. The results obtained in 265 out-patients undergoing colonoscopy confirm the efficacy, practicality and tolerability of the method.

After analysing previous investigations into the incidence of anastomotic dehiscence in colorectal surgery, the paper reports experience with a group of 27 patients treated by a "routine"-TPN after major surgery. In addition, a second group of 67 patients, treated by TPN alone after a postoperative complication, was included in this study. The results show the utility of TPN in the prevention or faster healing of anastomotic dehiscences.
