Randomized Controlled Trial
Day-case endoscopic totally extraperitoneal inguinal hernioplasty versus open Lichtenstein hernioplasty for unilateral primary inguinal hernia in males: a randomized trial.
Endoscopic totally extraperitoneal inguinal hernioplasty (TEP) is an accepted technique for the repair of recurrent and bilateral inguinal hernia, but its role in the management of unilateral primary inguinal hernia remains controversial. The current randomized trial was undertaken to compare the postoperative and 1-year outcomes of day-case TEP and open Lichtenstein hernioplasty for unilateral primary inguinal hernia in males. ⋯ Day-case TEP was superior to open Lichtenstein hernioplasty for the repair of unilateral primary inguinal hernia in males. The benefits of day-case TEP included less postoperative pain, a faster return to work, and a lower incidence of chronic groin pain.

Randomized Controlled Trial Multicenter Study
Alvimopan, a peripherally acting mu-opioid receptor antagonist, compared with placebo in postoperative ileus after major abdominal surgery: results of a randomized, double-blind, controlled study.
Alvimopan is a peripherally acting mu-opioid receptor (PAM-OR) antagonist for accelerating gastrointestinal recovery after surgery. ⋯ Alvimopan (6 or 12 mg) accelerates GI recovery and is well tolerated in patients undergoing open laparotomy.

Randomized Controlled Trial
Heating and humidifying of carbon dioxide during pneumoperitoneum is not indicated: a prospective randomized trial.
Carbon dioxide (CO2) pneumoperitoneum usually is created by a compressed gas source. This exposes the patient to cool dry gas delivered at room temperature (21 degrees C) with 0% relative humidity. Various delivery methods are available for humidifying and heating CO2 gas. This study was designed to determine the effects of heating and humidifying gas for the intraabdominal environment. ⋯ The intraabdominal environment in terms of temperature and humidity was similar in all the groups. There was no significant difference in the intraoperative body temperatures or the postoperative variable measured. No histologic changes were identified. Heating or humidifying of CO2 is not justified for patients undergoing laparoscopic bariatric surgery.
