A new self-restraining table-fixed abdominal retractor, thought up and built by Dr. Bonini, is described. This retractor is easy to construct and use and is recommended whenever very good exposure of the diaphragmatic vault and the supramesocolic area is required.

Histamine H2-receptor antagonists at conventional doses have proved only partly efficacious in the treatment of reflux oesophagitis. The aim of this study, therefore, was to compare the efficacy of high doses of nizatidine (300 mg b.i.d.) versus placebo in 117 patients with grade I and II oesophagitis. After 6 weeks' treatment, 70.6% of nizatidine-treated patients showed complete endoscopic healing against 25.4% of placebo-treated subjects (p less than 0.001). After 12 weeks, the respective healing rates were 77.5% and 47.4% (p less than 0.01). Nizatidine also proved significantly more effective than placebo in improving overall symptoms (p less than 0.05). Antacid intake was significantly greater in the placebo group (p less than 0.001). Both treatments were well tolerated. In conclusion, this study demonstrates that nizatidine at the dose of 300 mg b.i.d. for 6-12 weeks constitutes an effective treatment for patients with reflux oesophagitis.
Lipoma of the large bowel is an infrequent pathology. The Authors, on the basis of a review of the literature and of their own experience of two cases reported analyze the clinical features, macroscopic appearance, endoscopic signs which may serve as a guide to diagnose the disease. They stress the importance of colonoscopy for a correct diagnostic and therapeutic approach.
