Laparoscopic surgery without pneumoperitoneum.

The results of 43 laparoscopic surgeries performed with an abdominal wall retractor designed in the 3rd Surgical Service at "San Roque" Hospital are analyzed. Of them, 42 underwent cholecistectomy and one an endometrosic focus resection, placed in the Douglas sac. The results obtained have been good. There was almost no postoperatory pain due parietal wall traction. The hospital stay was less than 24 hours in 41 cases and less than 48 hours in two. We also point out the absence of complications and the advantages of the parietal traction compared with pneumoperitoneum.
