Laparoscopic cholecystectomy for acute cholecystitis in the elderly: is it safe?

BACKGROUND

The purpose of this study was to evaluate the outcome of laparoscopic cholecystectomy (LC) in patients with acute cholecystitis aged 75 years and older.

MATERIALS AND METHODS

A retrospective chart review was performed on the 1216 cholecystectomies performed in our department from 2000 to 2005. A total of 225 patients underwent attempted LC for acute cholecystitis, of whom 42 were more than 75 years old and 183 younger.

RESULTS

There was no difference in mean duration of symptoms before admission and length of hospital stay before surgery (3.8 d in elderly vs. 3.1 in younger patients, and 2.8 vs. 2.3 d, respectively). In all, 21% of the elderly patients had American Society of Anesthesiologists score III and IV. Mean operative time and conversion rate to open surgery were similar in both groups. Postoperative stay was longer in elderly (3.9 vs. 2.8). The postoperative complications rate and mortality were significantly higher in the elderly group (31% vs. 15%, and 4.8% vs. 0.5%, respectively).

CONCLUSIONS

LC in elderly patients suffering from acute cholecystitis is feasible and effective. It is associated with a higher rate of morbidity unrelated to the surgical site and mortality in elderly compared with younger patients. Stronger selection of elderly patients for surgery is needed.

Cholecystectomy deferral in patients with endoscopic sphincterotomy

BACKGROUND

Cholecystectomy is not required in up to 64% of patients who adopt a wait-and-see policy after endoscopic clearance of common bile duct stones. Although reports of retrospective cohort series have shown a higher mortality among patients who defer cholecystectomy, it is not known if this is due to the patients' premorbid health status or due to the deferral of cholecystectomy. Randomised clinical trials of prophylactic cholecystectomy versus wait-and-see have not had sufficient power to demonstrate differences in survival.

OBJECTIVES

To evaluate the beneficial and harmful effects of cholecystectomy deferral (wait-and-see) versus elective (prophylactic) cholecystectomy in patients who have had an endoscopic biliary sphincterotomy.

SEARCH STRATEGY

We searched The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Controlled Trials Register (CENTRAL) in The Cochrane Library, MEDLINE (1966 to 2007), EMBASE (1980 to 2007), and Science Citation Index Expanded without language restrictions until April 2007.

SELECTION CRITERIA

Randomised clinical trials comparing patients whose gallbladder was left in-situ after endoscopic sphincterotomy (wait-and-see group) versus patients who had cholecystectomy with either endoscopic sphincterotomy or common bile duct exploration (prophylactic cholecystectomy group), irrespective of blinding, language, or publication status.

DATA COLLECTION AND ANALYSIS

We assessed the impact of a wait-and-see policy on mortality. Secondary outcomes assessed were the incidence of biliary pain, cholangitis, pancreatitis, need for cholangiography, need for cholecystectomy, and the rate of difficult cholecystectomy. We pooled data using relative risk with fixed-effect and random-effects models.

MAIN RESULTS

We included 5 randomised trials with 662 participants out of 93 publications identified through the literature searches. The number of deaths was 47 in the wait-and-see group (334 patients) compared to 26 in the prophylactic cholecystectomy group (328 patients) for a 78% increased risk of mortality (RR 1.78, 95% CI 1.15 to 2.75, P = 0.010). The survival benefit of prophylactic cholecystectomy was independent of trial design, inclusion of high risk patients or inclusion of any one of the five trials. Patients in the wait-and-see group had higher rates of recurrent biliary pain (RR 14.56, 95% CI 4.95 to 42.78, P < 00001), jaundice or cholangitis (RR 2.53, 95% CI 1.09 to 5.87, P = 0.03), and of repeat ERCP or other forms of cholangiography (RR 2.36, 95% CI 1.29 to 4.32, P = 0.005). Cholecystectomy was eventually performed in 35% (115 patients) of the wait-and-see group.

AUTHORS' CONCLUSIONS

Prophylactic cholecystectomy should be offered to patients whose gallbladders remain in-situ after endoscopic sphincterotomy and common bile duct clearance.

Outcome of laparoscopic cholecystectomy in patients 80 years and older

Advanced age is associated with an increase in postoperative complications. This study assesses the indications and outcome for laparoscopic cholecystectomy (LC) in patients aged 80 years or older. Consecutive, unselected patients aged 80 years or over undergoing LC between 1991 and 2000 were included. A retrospective case review enabled analysis of clinical and operative factors together with in-hospital morbidity, 30-day mortality, and duration of hospital stay. A series of 117 patients, 79 women and 38 men with a median age of 83 years (range 80-93 years), underwent LC. Indications for LC were chronic cholecystitis in 62 (53%) patients, acute cholecystitis in 28 (24%), gallstone pancreatitis in 12 (10%), and other conditions in 15 (13%). Six (5%) patients required conversion to an open procedure. Overall, 26 (22%) patients developed a postoperative complication. There were no bile leaks or bile duct injuries. One patient, with gangrenous cholecystitis, died after LC. The median postoperative hospital stay was 3 days (range 1-31 days). LC can be performed safely with low morbidity in patients over age 80 years.

Pain and quality of life in patients with symptomatic, non-complicated gallbladder stones: results of a randomized controlled trial

BACKGROUND

Cholecystectomy is intended to relieve symptoms of gallstones, but unfortunately some patients will experience postcholecystectomy symptoms, including pain. There is limited information in the literature on gallstone-related pain and its influence on quality of life. The aim of this study was to examine how pain and quality of life in patients with symptomatic, uncomplicated gallbladder stones were affected by observation of their condition compared with removal of the gallbladder.

METHODS

One-hundred and thirty-seven patients were randomized to observation (watchful waiting; n = 69) or cholecystectomy (n = 68) and answered questionnaires on pain, quality of life (PGWB index and NHP Part II) at randomization and fixed intervals (6, 12 and 60 months). All gallstone-related events (hospital admission for pain, complications of gallstone disease and cholecystectomy) and crossover between treatment groups were recorded.

RESULTS

Of patients randomized to observation, 35 of 69 patients (51%) eventually underwent a cholecystectomy. Significant improvements in quality of life and pain scores were detected regardless of surgical treatment. Patients that subsequently experienced gallstone-related events had significantly higher pain scores at randomization than patients that did not experience any subsequent events, and this difference was maintained throughout follow-up.

CONCLUSIONS

Unexpectedly, in the majority of patients symptoms did abate without any significant differences between groups in pain and quality of life. Patients that had high intensity and frequency of pain at randomization had a higher risk of experiencing subsequent events.
