Randomised trial of laparoscopic versus open cholecystectomy for acute and gangrenous cholecystitis

BACKGROUND: Laparoscopic cholecystectomy (LC) has become the treatment of choice for elective cholecystectomy, but controversy persists over use of this approach in the treatment of acute cholecystitis. We undertook a randomised comparison of the safety and outcome of LC and open cholecystectomy (OC) in patients with acute cholecystitis. METHODS: 63 of 68 consecutive patients who met criteria for acute cholecystitis were randomly assigned OC (31 patients) or LC (32 patients). The primary endpoints were hospital mortality and morbidity, length of hospital stay, and length of sick leave from work. Analysis was by intention to treat. Suspected bile-duct stones were investigated by preoperative endoscopic retrograde cholangiography (LC group) or intraoperative cholangiography (OC group). FINDINGS: The two randomised groups were similar in demographic, physical, and clinical characteristics. 48% of the patients in the OC group and 59% in the LC group were older than 60 years. 13 patients in each group had gangrene or empyema, and one in each group had perforation of the gallbladder causing diffuse peritonitis. Five (16%) patients in the LC group required conversion to OC, in most because severe inflammation distorted the anatomy of Calot's triangle. There were no deaths or bile-duct lesions in either group, but the postoperative complication rate was significantly (p=0.0048) higher in the OC than in the LC group: seven (23%) patients had major and six (19%) minor complications after OC, whereas only one (3%) minor complication occurred after LC. The postoperative hospital stay was significantly shorter in the LC than the OC group (median 4 [IQR 2-5] vs 6 [5-8] days; p=0.0063). Mean length of sick leave was shorter in the LC group (13.9 vs 30.1 days; 95% CI for difference 10.9-21.7). INTERPRETATION: Even though LC for acute and gangrenous cholecystitis is technically demanding, in experienced hands it is safe and effective. It does not increase the mortality rate, and the morbidity rate seems to be even lower than that in OC. However, a moderately high conversion rate must be accepted.     

Cost-effectiveness of laparoscopic cholecystectomy versus open cholecystectomy

To assess the cost-effectiveness of laparoscopic cholecystectomy versus open cholecystectomy from the payer's perspective, we estimated the probabilities of potential outcomes of each procedure, associated quality-of-life effects, and related direct medical charges and incorporated these estimates into a computerized simulation model. The model projects that laparoscopic cholecystectomy will be more effective than open surgery in terms of total mortality and quality-adjusted survival, for both sexes and all ages. Projected 5-year cumulative charges are lower for laparoscopic cholecystectomy than for open cholecystectomy ($5,354 versus $5,525 for 45-year-old women; $6,036 versus $6,830 for 45-year-old men), and the differences increase substantially with increasing age. We concluded that laparoscopic cholecystectomy is likely to be less costly and more effective than open cholecystectomy for most patients, as long as it does not routinely require preoperative cholangiography and is not associated with increased professional fees or increased risks of retained stones or bile duct injury.     

Factors associated with successful laparoscopic cholecystectomy for acute cholecystitis

We have assessed the relationship between bone density, biochemistry and life-style factors in a cross-sectional study of 434 pre- and 357 postmenopausal women. Bone-mineral content (BMC) was measured in the non-dominant forearm using single-photon densitometry. Bone mass was corrected for bone size (BMC2) in a sub-set of 263 subjects. Correlation statistics and multiple regression analyses were used to identify physical and biochemical measurements that could be used to best predict BMC or BMC2. These were combined with lifestyle factors, using multiple logistic regression analysis, to identify women at risk of low bone density. Cut-off values were taken as the 5th percentile of the bone density distributions in pre-menopausal women. In postmenopausal women, using BMC2 values to define "risk", and using age, creatinine, alkaline phosphatase, thyroxine treatment, and calcium supplementation as predictors, a sensitivity of 73% and a specificity of 95% were achieved. Such a model may be of use as a "first pass" screening test for osteoporosis.     

Comparison of laparoscopic and minilap cholecystectomy for acute cholecystitis

The charts of all patients with acute cholecystitis undergoing either laparoscopic or minilap cholecystectomy at the Chinle Comprehensive Health Care Facility between October 1, 1991, and August 15, 1993, were retrospectively reviewed. During that period, 54 patients underwent laparoscopic cholecystectomy and 45 patients had minilap procedures. The two groups had similar mean age, sex distribution, temperature, leukocyte count, gallbladder wall thickness, and duration of preoperative symptoms. While laparoscopic cholecystectomy took an average of 16 min longer to perform than minilap cholecystectomy, patients who had laparoscopic cholecystectomy had less blood loss, reduced postoperative narcotic needs, and shorter hospital stays.     

Immediate laparoscopic cholecystectomy as definitive therapy for acute cholecystitis

The objective of this study was to determine the safety and efficacy of immediate laparoscopic cholecystectomy in the management of acute calculous cholecystitis. A prospective data collection was performed on all patients admitted to one surgical service over a 2-year period. The patients were managed by a uniform protocol consisting of (1) preoperative ERCP when common duct stones were suspected; (2) operation within 24 h of diagnosis; and (3) selective operative cholangiography. Previous surgery was not a contraindication to inclusion. The setting was an urban teaching hospital. There were 52 patients, 34 females and 18 males. Nineteen had undergone previous abdominal surgery. Five patients had preoperative ERCP and five had intraoperative cholangiography. The patients underwent laparoscopic cholecystectomy 0.8 +/- 0.4 days postadmission. Four (7.7%) were converted to open cholecystectomy. Fifty-eight percent had spillage of bile and/or stones. Patients went home 2.3 +/- 1.6 days postoperatively. There were no deaths and two complications: a subhepatic biloma and a superficial wound infection. Follow-up of all patients has revealed no late complications. We conclude: (1) Immediate laparoscopic cholecystectomy is safe and effective for acute cholecystitis even when complicated by previous surgery, inflammatory adhesions, and gangrene. (2) Intraoperative spillage of bile and stones does not lead to an increase in early complications. (3) Cholangiography is needed only when clinically indicated. (4) Laparoscopic cholecystectomy should be the treatment of choice for patients admitted for acute cholecystitis.     

Randomized trial of early versus delayed laparoscopic cholecystectomy for acute cholecystitis

BACKGROUND: The aim of this prospective randomized study was to define the optimum management between early and delayed laparoscopic cholecystectomy for patients with acute cholecystitis. METHODS: Patients were randomized to receive either early laparoscopic cholecystectomy within 24 h of randomization or initial conservative treatment followed by delayed laparoscopic cholecystectomy 6-8 weeks later. RESULTS: There were 53 patients in the early group and 51 in the delayed group. There was no significant difference in conversion rate (early 21 per cent versus delayed 24 per cent), postoperative analgesic requirement (1 versus 2 doses) and postoperative complications. However, the early group had significantly longer operating time (122.8 versus 106.6 min, P = 0.04) and shorter total hospital stay (7.6 versus 11.6 days, P < 0.001). CONCLUSION: Early laparoscopic cholecystectomy is safe and feasible for acute cholecystitis with the additional benefit of shorter total hospital stay. Apart from a shorter operating time, treating patients with delayed laparoscopic cholecystectomy does not offer additional benefit.     

Activation of coagulation and fibrinolysis in open and laparoscopic cholecystectomy

BACKGROUND: Activation of coagulation and fibrinolysis occurs as a stress response to surgery and may predispose the patient to thromboembolic complications. Other components of the surgical stress response (cytokine release, neurohumoral response, etc.) have been shown to differ between laparoscopic and open cholecystectomy, and the aim of this study was to investigate the effects of laparoscopic and open surgery on the coagulation and fibrinolytic pathways. METHODS: Fourteen patients undergoing laparoscopic cholecystectomy and 12 patients undergoing open cholecystectomy had blood taken in the perioperative period for fibrinopeptide A (FPA) prothrombin fragment F1.2, antithrombin 3, tissue plasminogen activator (tPA) and its fast-acting inhibitor plasminogen activator inhibitor-1 (PAI-1 antigen and activity), and the euglobulin clot lysis time (ECLT). RESULTS: The only significant differences between the two groups occurred 6 h after surgery when the ECLT was longer (p < 0.005; Mann Whitney), and PAI-1 antigen and activity were higher (p < 0.01 and p < 0.001, respectively; Mann Whitney) after open cholecystectomy than laparoscopic cholecystectomy. CONCLUSIONS: Other changes in fibrinolysis and coagulation were similar for open and laparoscopic cholecystectomy. With respect to hemostasis, laparoscopic cholecystectomy does not increase the risk of thromboembolic complications compared to the conventional procedure.     

Prospective randomized study of early versus delayed laparoscopic cholecystectomy for acute cholecystitis

We asked whether the likelihood for mice of the C57BL/6J strain to develop glucose intolerance when fed a high-fat diet is related to the increase in circulating levels of leptin or free fatty acids (FFA). We therefore administered a high-fat diet (58% fat) or a control diet (11% fat) for 1.5 years. NMRI mice were used as a more glucose-tolerant control group. After a high-fat diet, the area under the glucose curve following an intraperitoneal glucose challenge (1 g/kg) increased more markedly in C57BL/6J mice (by 42+/-8%) than in NMRI mice (by 21+/-3%, P = 0.007). Plasma levels of insulin, leptin and FFA increased in both strains of mice, whereas plasma glucose levels were elevated after the high-fat diet only in C57BL/6J mice. The slope of the relationship between body weight and plasma leptin was higher in C57BL/6J mice than in NMRI mice. suggesting leptin insensitivity. Circulating leptin correlated to circulating insulin in both strains of mice, whereas plasma FFA correlated to plasma insulin in NMRI mice but not in C57BL/6J mice. These correlations remained significant after adjustment for body weight. The results show that elevated leptin and FFA levels evolve after high-fat feeding in mice, in conjunction with evolvement of glucose intolerance and hyperglycemia.     

Effects of surgical trauma of laparoscopic vs. open cholecystectomy

The effects of surgical trauma resulting from laparoscopic cholecystectomy and open cholecystectomy, were compared by assessing the postoperative acute phase alterations of selected plasma proteins, hormones and lymphocyte subpopulations in fifty-seven patients prior to elective cholecystectomy. Patients were prospectively randomized to undergo either laparoscopic cholecystectomy (n = 30) or open cholecystectomy (n = 27). Duration of operation and general anesthesia was similar in the two patient groups. The laparoscopic cholecystectomy patients had a shorter postoperative stay in hospital (3.1 (0.5) days vs. 7.1 (1.6) days; p < 0.001). In open cholecystectomy patients a significantly greater postoperative acute phase increase in plasma C-reactive protein (p < 0.001), cortisol (p < 0.05), and prolactin blood level (p < 0.001) was recorded. The postoperative acute phase decrease in the blood total-T-lymphocyte count (CD3 cells) and in the activated-lymphocyte count (OKDR cells) was significantly greater after open cholecystectomy (p < 0.05). These results, showing that acute phase responses are less marked after laparoscopic cholecystectomy than after open cholecystectomy, support the concept that the laparoscopic procedure is less traumatic.     

Surgical rates and operative mortality for open and laparoscopic cholecystectomy in Maryland

BACKGROUND: Since 1989, laparoscopic cholecystectomy has been widely adopted as a treatment for gallstone disease. We analyzed the association between the introduction of this procedure and three variables: the rate at which cholecystectomy was performed in Maryland, the characteristics of patients undergoing cholecystectomy in routine clinical practice, and operative mortality. METHODS AND RESULTS: We used 1985-1992 hospital-discharge data from all 54 acute care hospitals in Maryland, to identify open and laparoscopic cholecystectomies, characteristics of patients undergoing these procedures, and deaths occurring during hospitalizations in which these procedures were performed. The annual rate of cholecystectomy, adjusted for age, rose from 1.69 per 1000 state residents in 1987-1989 to 2.17 per 1000 residents in 1992, an increase of 28 percent (P < 0.001). As compared with patients undergoing open cholecystectomy, patients undergoing laparoscopic cholecystectomy tended to be younger, less likely to have acute cholecystitis or a common-duct stone, and more likely to be white and have private health insurance or belong to a health maintenance organization (P < 0.001). Although the operative mortality associated with laparoscopic cholecystectomy was less than that with open cholecystectomy (adjusted odds ratio, 0.22; 95 percent confidence interval, 0.13 to 0.37) and the overall mortality rate for all cholecystectomies declined from 0.84 percent in 1989 to 0.56 percent in 1992, there was no significant change in the total number of cholecystectomy-related operative deaths because of the increase in the cholecystectomy rate. CONCLUSIONS: In Maryland, although the adoption of laparoscopic cholecystectomy has been accompanied by a 33 percent decrease in overall operative mortality per procedure, the total number of cholecystectomy-related deaths has not fallen because of a 28 percent increase in the total rate of cholecystectomy.
