To assess the influence of hyperoxygenation on surgical site infection by using the most homogeneous study population.

Laparoscopic management of acute cholecystitis is feasible and safe. Considering the factors discussed above, lowering the threshold for conversion is necessary in selected cases to maintain low morbidity rate. Integrating laparoscopic cholecystectomy for acute cholecystitis into surgical residency should be studied.

Aspiration of hydatid cysts and instillation of scolicidal fluid as part of the surgical treatment should be done very carefully to prevent any spillage that might cause anaphylaxis and dissemination of the disease. We describe herein a laparoscopic technique for safe aspiration of hydatid cysts of liver by using an assembled large, transparent trocar sleeve with a beveled tip. The method described allows laparoscopic access even to hydatid cysts that are located under the diaphragm.

The loose seton technique for trans-sphincteric anal fistula carries favorable results and can be safely applied while preserving the external sphincter function. We also recommend repeating the technique in case of post-operative fistula recurrence or persistence.

Seed bezoars found in the rectum were the most common cause of fecal impaction requiring hospitalization, probably to the result of the eating habits in the Middle East. The consumption of seeds with shell fragments or fruits containing many seeds (such as the prickly pear) should be accompanied by the awareness that large quantities may cause fecal impaction.

The laparoscopic isolated hypobaric technique that we developed and use is safe and feasible for almost all kinds of hepatic and extrahepatic abdominal hydatid cysts.

We describe (for the first time) a laparoscopic approach to repair an acquired superior triangle lumbar hernia in a morbidly obese woman by using prosthetic mesh. Such a technique provides an excellent anatomic view, thus avoiding injury to structures in proximity to the hernia during repair; eventually the well-known advantages of such approach result.
