The aim of this study was to assess the outcome of laparoscopic colorectal surgery in obese patients and compare it to that of a nonobese group of patients who underwent similar procedures. ⋯ Laparoscopic colorectal segmental resections are feasible in obese patients. However, increased rates of conversion to laparotomy should be anticipated and the risk of postoperative complications is significantly increased, prolonging the length of hospitalization when compared to that of nonobese patients.

Wrap disruption or intrathoracic herniation of a fundoplication is a dreaded complication of laparoscopic foregut surgery. This problem may often be related to postoperative nausea and vomiting (PONV). This study aimed to investigate the occurrence of PONV and its management in patients undergoing laparoscopic foregut procedures. ⋯ Nausea after laparoscopic foregut procedures is common, occurring twice as often on the nursing unit as in the PACU. The occurrence of PONV leads to a longer hospital stay, and can result in significant sequelae requiring reoperation. The use of preoperative or intraoperative antiemetics does not alter the frequency of postoperative nausea, suggesting the need to develop effective preemptive regimens for patients undergoing laparoscopic foregut procedures. The high rate of PONV and its potential risk of damage to a fundoplication and hiatal hernia repair should lead surgeons to consider whether laparoscopic foregut procedures should ever be performed on an outpatient basis.

During laparoscopic cholecystectomy, distended gallbladder can create exposure difficulties, that precludes adequate visualization, thus rendering laparoscopic dissection impossible and even unsafe. To overcome this problems, we devised a simple technique for the decompression of distended gallbladders.

Randomized Controlled Trial Comparative Study Clinical Trial
Helium vs carbon dioxide gas insufflation with or without saline lavage during laparoscopy.
Helium is an inert gas that, if used for insufflation during laparoscopy, may be followed by less postoperative pain than carbon dioxide (CO2) insufflation, due to a more limited effect on intraabdominal pH and metabolism. Saline lavage has also recently been shown to reduce postoperative pain following laparoscopic surgery. To evaluate these possibilities and to better define the clinical safety of helium insufflation, we undertook a prospective randomized trial comparing CO2 and helium insufflation with or without saline lavage in patients undergoing elective laparoscopic upper abdominal surgery. ⋯ The use of helium insufflation for laparoscopic surgery, while not associated with any significant adverse sequelae, was not associated with less postoperative pain in this trial. The use of saline peritoneal lavage was associated with less pain in the early postoperative period.
