The case of a healthy 59-yr-old man who underwent elective laparoscopic extraperitoneal inguinal hernia repair and general anaesthesia is presented. After one hour of surgery, a sudden increase in the FETCO2 from 5.0% to 9.4% in relation to a massive subcutaneous emphysema, but without any haemodynamic instability, was noticed. The acute rise of FETCO2 was the first sign of an abnormal event. Nevertheless, subcutaneous emphysema was diagnosed with chest wall examination and palpation. Subcutaneous emphysema and hypercarbia are potential complications of laparoscopic surgery, but are more likely to occur in extraperitoneal surgery, since insufflated CO2 can diffuse easily into the surrounding tissues. High insufflation pressures will increase chances of this occurring and was the most likely cause of this complication. This case encouraged us to make recommendations for the management of laparoscopic extraperitoneal surgery which included: monitoring of CO2 insufflation pressure, routine examination and palpation of chest wall, use of N2O with caution, adjusting ventilation to physiological FETCO2 and excluding other causes of subcutaneous emphysema and hypercarbia.

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.

We report on a patient who developed subcutaneous emphysema with hypercarbia during an endoscopic, totally extraperitoneal (TEP) repair of an inguinal hernia. The possible mechanisms of carbon dioxide (CO2) insufflation causing emphysema of the subcutaneous tissues are discussed and ways to prevent it are proposed.

We experienced an extremely rare complication during performance of laparoscopic totally extraperitoneal (TEP) inguinal hernia repair for a 57-year-old healthy man. About 50 minutes after CO(2) insufflation, the patient developed tachycardia, hypoxemia, hypercapnia and an increased airway pressure. Right pneumothorax with subcutaneous emphysema was recognized on the emergency chest X-ray and this was successfully treated by chest tube insertion. Anesthesiologists should be aware of the possible occurrence of pneumothorax during laparoscopic TEP hernia repair.

Subcutaneous emphysema (SE) is a rare complication of laparoscopic procedures, with an incidence rate of only 0.43-2.3%. In this report, we present a case of a 28-year-old male who underwent an elective laparoscopic inguinal hernia repair and developed surgical emphysema, hypercarbia and respiratory acidosis intraoperatively. Based on our findings, we concluded that regardless of the low incidence of SE, awareness of the associated risk factors should be ensured to avoid laparoscopic procedure-related complications.
