In patients undergoing elective LC, antibiotic prophylaxis is justified only in high-risk patients. In all other patients, antibiotic prophylaxis does not seem to affect the incidence of postoperative infective complications. In low-risk patients, eliminating the unnecessary use of prophylactic antibiotics would result in a cost reduction; moreover, it would lower the risk of adverse reaction and reduce microbial resistance.

These findings suggest that the antioxidant defense system is stimulated less with less oxidative stress, providing further evidence to support the opinion that LC is a safe technique.

Spontaneous perforation of gastric cancer is a serious complication with a very high incidence of mortality. In order to evaluate the prognostic factors influencing mortality in patients with gastric tumour perforations and to clarify the optimal surgical treatment, the records of patients at one centre during a 5-year period were evaluated retrospectively. Between 1995 and 2000, 14 patients with perforated gastric cancer were operated on in the Emergency Surgical Unit of a Turkish Hospital. This figure represents 3% of all the patients with gastric cancer who were treated during the same period. The hospital mortality was 36% in patients with perforations. The duration of symptoms suggesting perforation and the presence of pre-operative shock were predictive factors of mortality. It was concluded that those patients with pre-operative shock and delayed diagnosis should be treated with extra caution to decrease mortality. Perforation and peritonitis must be treated initially and elective radical surgery delayed.
