title: Laparoscopic cholecystectomy: anesthetic implications.
abstract: Laparoscopic cholecystectomy is a relatively new surgical procedure, enjoying ever-increasing popularity and presenting new anesthetic challenges. The advantages of shorter hospital stay and more rapid return to normal activities are combined with less pain associated with the small limited incisions and less postoperative ileus compared with the traditional open cholecystectomy. Complications are mostly due to traumatic injuries sustained during blind trocar insertion, and physiologic changes associated with patient positioning and pneumoperitoneum creation. The choice of anesthetic technique for laparoscopic cholecystectomy is limited most frequently to general anesthesia. Controlled ventilation avoids hypercarbia, and an anesthetic technique incorporating antiemetics and nonsteroidal antiinflammatory agents has reduced postoperative nausea and vomiting. The use of nitrous oxide and narcotics during laparoscopic cholecystectomy is controversial. Laparoscopic cholecystectomy is a major advance in the management of patients with symptomatic gallbladder disease. However, in the present era of cost containment, older and sicker patients may present for this procedure on the day of surgery without adequate preoperative evaluation. Anesthesiologists thus should be prepared to recommend conversion to an open procedure if hemodynamic, oxygenation, or ventilation difficulties occur during the procedure.
