The development of nonbladed obturators with integrated stability sleeves allows for creation of a muscle-splitting dilated laparoscopic port site with minimal abdominal wall defects after removal of trocar sleeves. Our objective was to determine the safety of using nonbladed obturators and not closing laparoscopic fascial port sites. Seventy patients underwent various laparoscopic procedures including the following: seven laparoscopic Roux en Y gastric bypasses, 21 laparoscopic cholecystectomies, 23 laparoscopic hernia repairs, 10 laparoscopic Nissen fundoplications, two laparoscopic appendectomies, two laparoscopic liver biopsies, one laparoscopic common bile duct exploration, one laparoscopic jejunal resection, one laparoscopic low anterior resection, one laparoscopic splenectomy, and one bedside diagnostic laparoscopy. A total of 180 laparoscopic port sites did not undergo fascial closure involving 110 10- to 12-mm ports. One hundred eighty nonbladed trocars were inserted without complication during laparoscopic surgery. In all cases the nonbladed obturator did not cause bleeding or injure viscera. Upon removal of large laparoscopic ports, the fascial defect was less than 6 to 8 mm, and the muscles of the abdominal wall covered the port site defect. The anterior fascial defect did not line up with the posterior fascial defect after removal of CO2 insufflation. No patients have developed ventral incisional hernias in the postoperative period (median follow-up of 11 months). We conclude that the use of nonbladed laparoscopic trocars is a safe technique with the ability to visualize dissection through the abdominal wall layers to create the smallest port dissection without bleeding or cutting muscle fibers. The ability to split the abdominal wall musculature allows the surgeon to forego closure of the small fascial defect.
