Randomized Controlled Trial
Prospective randomized study on perioperative enteral immunonutrition in laparoscopic colorectal surgery.
Perioperative nutrition for patients undergoing colon surgery seems to be effective in reducing catabolism and improving immunologic parameters. A relatively low-fiber and highly absorbable diet may facilitate the intestinal cleansing and loop relaxation fundamental for laparoscopic surgery with a lower dose of iso-osmotic laxative. ⋯ Perioperative immunonutrition proved to be safe and useful in increasing the perioperative immunologic cell response. It may contribute toward improving the preparation and relaxation of the intestinal loops despite the shorter intestinal preparation.

Obesity decreases health-related quality of life, but bariatric surgery improves it. This study evaluates the effect of laparoscopic Roux-en-Y gastric bypass, postoperative complications, and percentage of excess body weight loss on quality of life. ⋯ Health-related quality of life in bariatric patients is worse than in controls, but it improves 1 and 2 years after laparoscopic Roux-en-Y gastric bypass. Complications or < or = 50% excess body weight loss slightly decreases this improvement.

Comparative Study
The use of tissue sealant to prevent fistula formation after laparoscopic distal pancreatectomy.
Pancreatic fistula occurs in about 20% of patients undergoing laparoscopic pancreatectomy. A variety of techniques have been described to decrease this rate, with limited success. Fibrin sealants are products that promote the adhesion of tissue surfaces to each other. This report demonstrates the use of fibrin sealants to decrease the incidence of pancreatic fistula. ⋯ Although this series was small, it does suggest that the use of fibrin sealant may reduce the incidence of postoperative pancreatic fistula formation after laparoscopic distal pancreatectomy.

Minimally invasive esophagectomy has the potential to minimize the morbidity of esophageal resection and is particularly suited to the transhiatal approach. This report details our experience with this technique and the lessons we have learned. ⋯ Minimally invasive transhiatal esophagectomy is feasible in our unit, with acceptable mortality. The high rate of anastomotic stenosis has resulted in a change to a semimechanical, side-to-side isoperistaltic technique. The high rate of recurrent laryngeal nerve injuries has resulted in the avoidance of metal retractors at the tracheo-esophageal groove.

Iatrogenic bile duct injury carries high morbidity. After the introduction of laparoscopic cholecystectomy the incidence of these injuries has at least doubled, and even after the learning curve, the incidence has plateaued at the level of 0.5%. ⋯ Most of the minor bile duct injuries, including cystic duct leaks and bile duct strictures, are well treatable with endoscopic techniques, whereas most of the major injuries require operative treatment, which at optimal circumstances gives good results.
