Laparoscopic cholecystectomy is a relatively new surgical procedure which is 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. The efficacy of laparoscopic appendectomy and hemicolectomy has been recently evaluated. However, there have been no prospective randomized studies to date comparing laparoscopic with traditional laparotomy techniques. The physiological effects of prolonged pneumoperitoneum and the longer duration of surgery with the laparoscopic techniques are of concern. The application of laparoscopic inguinal hernia repair may be limited because, unlike traditional surgical hepair, general anesthesia is required and concerns have been expressed about the duration of surgery and the possibility of hernia recurrence. Notwithstanding case reports and series describing successful diaphragmatic and hiatus hernia repair using a laparoscopic surgical technique, the frequently encountered complications of cervical surgical emphysema, pneumothorax, and pneumomediastinum, attributed to passage of insufflating gas through weak points or defects in the diaphragm, must be of major concern. Anesthesiologists must maintain a high index of suspicion for these potential complication and must undertake appropriate monitoring. If there is clinical evidence of a tension pneumothorax, immediate chest tube decompression is indicated. Intraoperative complications of laparoscopic surgery are mostly due to traumatic injuries sustained during blind trocar insertion and physiological changes associated with patient positioning and pneumoperitoneum creation. The choice of anesthetic technique for upper abdominal laparoscopic procedures is most frequently limited to general anesthesia. Controlled ventilation avoids hypercarbia, and an anesthetic technique incorporating antiemetics and nonsteroidal anti-inflammatory agents has reduced postoperative nausea and vomiting following laparoscopic cholecystectomy. The use of nitrous oxide during laparoscopic procedures remains controversial. Laparoscopic cholecystectomy is a major advance in the management of patients with symptomatic gall-bladder 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 should thus be prepared to recommend deflation of the pneumoperitoneum and possibly conversion to an open procedure if hemodynamic, oxygenation, or ventilation difficulties arise during the procedure.

During a 16-month period, 15 neurologically impaired infants and children for whom medical treatment failed underwent laparoscopic fundoplication. The indications for surgery included feeding difficulties, vomiting, and recurrent chest aspiration. The patients' weight range was 3.9 and 42 kg (6 weighed less than 12 kg). Access was modified according to each patient's size and shape. The average operating time was 2.2 hours (range, 1.4 to 3) for fundoplication and 3.1 hours (range, 2.3 to 4.1) for fundoplication with gastrostomy. Two patients had conversion to open surgery because of hypercarbia or perforated oesophagus. Use of postoperative analgesia was limited to the first 24 hours, and fluid intake and feeding were begun on days 1 and 2, respectively. Gas bloating was common postoperatively, and diarrhoea developed in three children. Twelve patients had clinical improvement, and a recurrent hiatus hernia developed in one. Laparoscopic fundoplication can be successful; however, awareness of the differences in technique for paediatric (disabled children in particular) and adult patients is essential. The technique deserves further investigation.

Although laparoscopic fundoplication is now performed commonly in children, its long-term results in neurologically impaired (NI) children is unknown. We present a single surgeon's experience. During an 8.5 year period, 54 consecutive NI children (age 5 months to 16 years; weight 2.7 to 42 kg) who had failed medical treatment for severe gastroesophageal reflux (GER) underwent laparoscopic Nissen fundoplication without (7) or with (47) gastrostomy. Indications for surgery included failure to thrive and feeding difficulties in all, major vomiting in 42, recurrent chest infections in 44, and inability to take oral medication in 14. Hiatus hernia was present in 14 and delayed gastric emptying in 6 patients. Eight (15%) had undergone previous abdominal surgery. Access was modified according to individual anatomy and 4 or 5 cannulae were used in each patient. Postoperative epidural/morphine analgesia was used in the first 12 to 24 hours, and fluid intake and feeding were started on day 1 and 2, respectively. The average operating time for fundoplication was 2.2 hours (range 1.05 to 3) and for fundoplication and gastrostomy 2.3 hours (range 1.22 to 4.10). Three patients had conversion to open surgery (1 perforated esophagus, 1 hypercarbia and hepatomegaly, 1 camera failure). There were no other operative complications or mortality. One child with Down syndrome developed a food bolus obstruction 3 days postoperatively. The vast majority of patients were discharged home 3 to 4 days following fundoplication and 5 to 7 days following fundoplication and gastrostomy. Postoperative gas bloat was common, diarrhea developed in 4, dumping in 3, and major gastrostomy infection in 1 case. During follow-up (median 5.2, range 3 months to 8.6 years), 9 (16%) children showed signs of persistent/recurrent problems. Investigations showed a recurrent hiatus hernia in 1 (requiring re-operation) and minor reflux in 3 patients. To date 6 (11%) children have died of their background conditions. In NI children, laparoscopic fundoplication is safe and successful. Awareness of the differences in access and risks for NI and normal children is important. Compared with historical data for open technique, laparoscopic fundoplication produces lower mortality and morbidity and similar intermediate and long-term results.
