The Authors report the results of the management of ischaemic colitis in a surgical unit dedicated to elderly patients. Sixty-two elderly patients affected by ischaemic colitis were observed consecutively in the Surgery Unit of the University of L'Aquila from 1986 to 2004. The clinical records of the patients were retrospectively reviewed in order to assess clinical, biohumoral, endoscopic and x-ray findings pre- dictive of the most suitable type of treatment.

Gastrointestinal stromal tumours (GIST) are rare neoplasms originating from connective tissue in the digestive tract with an incidence of less than 1% and account for most non-epithelial primitive digestive tumours. Metastasis diagnosed at the time of disease discovery confirms GIST malignancy. Kit protein, a trans-membrane tyrosine kinase receptor of staminal cells, is characteristically expressed by GIST.

We analyzed our case series in order to evaluate the evolution of our laparoscopic technique in ergonomic and cosmetic terms, leading to the right compromise between these aspects. We retrospectively analyzed 136 diagnostic laparoscopies for suspected appendicitis, using scheme A in the first 98 cases (one 10/12-mm umbilical trocar for the optics and two 5-mm operative trocars placed above the pubis on the right and left side) and scheme B in the other 38 cases (one 10/12-mm umbilical trocar for the optics and two 5-mm operative trocars, one placed over the pubis and the other one on the right hip, just on the umbilical line). The diagnosis of appendicitis was confirmed in 117 patients, while other diseases were present in 19 patients.

The insufflation pressure used for laparoscopic cholecystectomy is usually 12-15 mm Hg, and a pneumoperitoneum with carbon dioxide has a significant effect on both cardiovascular and respiratory function. These effects are transient in young, healthy patients, but may be dangerous in ASA III and IV patients with a poor cardiac reserve. This study was designed to assess the feasibility of performing laparoscopic cholecystectomy at 6.
