Considerations concerning laparoscopic cholecystectomy in the extremely elderly.

Background: Since octogenarians become a growing part of the population and surgical care is possible in them, this study was conducted to evaluate the outcome of laparoscopic cholecystectomy in patients 80 years of age and over.

Methods: From June 1993 to May 2006, a total of 1263 patients underwent a laparoscopic cholecystectomy, applying the four-trocar American technique; 21 among them were >/=80 years. We retrospectively reviewed patients' age, gender, indication for surgery, comorbid conditions, American Society of Anesthesiologists (ASA) score, conversion to open procedure, postoperative complications, and length of hospital stay.

Results: The mean age in the >/=80 group was 82.5+/-3 and 57% were women, while in the <80 group 72% of patients were women. Recurrent biliary colic was the most frequent (62%) indication for surgery among the elderly patients. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy were performed preoperatively in 6 elderly patients (29%); there were 4 cases of acute calculus pancreatitis and 2 cases of acute cholangitis. A high surgical risk (ASA score of III and IV) was estimated in 11 patients (52%) from the >/=80 group versus 32% in the <80 group (P =0.047). Conversion rate was higher (19%) and hospital stay was longer (4.9 days) in the >/=80 group, compared to younger patients (P =0.01). Mortality was zero and morbidity was 14% versus 3% in the <80 group (P =0.03), including 1 case of postoperative bleeding, 1 case of wound infection, and 1 case of pulmonary atelectasis, respectively.

Conclusions: Laparoscopic cholecystectomy in the extremely elderly is safe and well tolerated; however, it is associated with a higher conversion rate, increased morbidity, and a longer hospital stay.
