Laparoscopic approach to gallstones in the morbidly obese patient.
Obesity has been suggested to be a contraindication to laparoscopic cholecystectomy (LC). In our center, in which all patients presenting with symptomatic gallstones are considered to be candidates for LC, 24 of the first 325 LC candidates were retrospectively found to be morbidly obese. In all, 20 were women and 4 were men. The average age was 51 years (range 32 to 83 years); the average height and weight amounted to 72 inches and 298 pounds, respectively, for men; and 63.5 inches and 258 pounds, respectively, for women. One-third of these patients suffered from acute cholecystitis, and more than 50% had undergone prior abdominal surgery. The average duration of LC in these subjects was 114 min., which was 25% longer than that in nonobese patients. The average length of the hospital stay was 1.6 days, with patients returning to normal activities within an average of 6.5 days. There was no major morbidity and no mortality. Since obese patients tolerated LC as easily as did normal patients, we concluded that obesity is an indication rather than a contraindication to LC.
Laparoscopic treatment of acute cholecystitis.
Retrospective review of the first 210 patients treated by laparoscopic cholecystectomy revealed 55 patients (26%) with acute cholecystitis diagnosed preoperatively or intraoperatively. Average age was 52 years amongst 38 women and 17 men. Cardiac history was present in 4%, pulmonary disease was noted in 9%, and other significant medical history was found in 10%. Abnormal preoperative laboratory values (white blood cell count, liver function) were seen in 80%. Operations averaged 104 minutes. Dissection was performed with the potassium titanyl phosphate (KTP) laser in 9%, neodymium-doped yttrium aluminum garnet (Nd Yag) laser in 20%, and electrocautery alone in 71%. Average body habitus was 5 ft 9 in, 178 lb for men and 5 ft 5 in, 155 lb for women. Average length of stay was 2.6 days. Thirty-eight patients (69%) left the hospital in < 2 days. Postoperative complications included one case each of urinary retention, pneumonia, myocardial infarction, and three cases of postoperative fever. Drains were placed in 10 patients (18%). There was no mortality. Suggestions are made for technical considerations that make laparoscopic cholecystectomy a safe and efficient approach to acute cholecystitis.
A comparison of laparoscopic and open treatment of acute cholecystitis.
A retrospective review of 200 patients with acute cholecystitis, half of whom underwent open cholecystectomy and half of whom underwent laparoscopic cholecystectomy, was performed. The two groups were compared for demographic characteristics, operative course, cost of intervention, and surgical outcome. Laparoscopic cholecystectomy for acute cholecystitis was accomplished with an acceptable morbidity and provided an earlier release from the hospital and return to normal activities with a significant economic savings as compared to the traditional open approach.
