The five years survival rate for patients with gastric cancer is 15-25%. With the aim of improving survival, chemotherapy has been used in different adjuvant settings. Similarly, but with the aim of improving quality of life and prolonging life, chemotherapy has been used extensively in metastatic disease. In this review we have included studies of systemic and intraperitoneal chemotherapy given before, during or after operation and for advanced disease. A meta-analysis has been made on the 21 randomised studies that used adjuvant systemic chemotherapy postoperatively. A significant survival benefit for the patients treated postoperatively compared with controls was identified (odds ratio (OR) 0.84, 95% confidence interval (CI) 0.74 to 0.96). When western and Asian studies were analysed separately we found no survival benefit for the treated patients in the western groups (OR 0.96 (95 CI 0.83 to 1.12)). Flaws in the conduct of several trials made it difficult to draw firm conclusions, including the exclusion of a small but clinically meaningful survival benefit. Preoperative or neoadjuvant chemotherapy has shown effects in some patients, but no significant benefit was found in the few randomised studies. The few studies that reported intraperitoneal therapy showed no detectable survival benefit either. In patients with advanced disease, four small randomised studies found significantly longer survival in the treated patients. The survival benefit is in the range of 3-9 months, and there were also improvements of the quality of life. Several drug combinations have been tested, however, with no confirmed superiority for a particular regimen. ⋯ Adjuvant chemotherapy cannot be recommended as a routine because of the lack of confirmed beneficial effects. Some patients with advanced disease will have a clinically important benefit from palliative chemotherapy, so this can be recommended for patients who are otherwise in good health.

To evaluate recurrence rate and chronic groin pain three years after hernia repair and to validate a postal questionnaire with selective physical examination as a method of follow-up. ⋯ The incidence of recurrence and chronic pain after hernia repair requires continuous audit in non-specialised units. Participation in a register and follow-up by a three-item questionnaire and selective physical examination provides a solid basis for quality control.

Randomized Controlled Trial Comparative Study Clinical Trial
Local anaesthesia in elective inguinal hernia repair: a randomised, double-blind study comparing the efficacy of levobupivacaine with racemic bupivacaine.
To assess the use of infiltration with local anaesthetics levobupivacaine and bupivacaine, during inguinal hernia repair. ⋯ Levobupivacaine exerts a similar anaesthetic and analgesic effect to racemic bupivacaine when infiltrated both intraoperatively and during the early postoperative period for elective inguinal hernia repair.

To evaluate patients with stab wounds of the anterior abdomen with diagnostic peritoneal lavage (DPL), by using initial aspiration of gross blood from the lavage catheter of more than 10 ml or red blood cell (RBC) count in the lavage fluid of more than 10,000/mm3 as criteria for exploratory laparotomy. ⋯ The use of DPL in patients with stab wounds of the anterior abdomen, using initial aspiration of gross blood from the lavage catheter of more than 10 ml or RBC count in the lavage fluid of more than 10,000/mm3 as positive criteria for exploratory laparotomy, is safe and practical.

Comparative Study
Proteolysis in severe sepsis is related to oxidation of plasma protein.
To test the hypothesis that the oxidation of proteins is part of the mechanism of proteolysis in catabolic states. ⋯ Severe sepsis results in oxidation of plasma proteins and this precedes and is related to the loss of body protein.
