Background: Besides rate and extent of weight loss, little is known regarding demographic factors predicting interval cholecystectomy (IC) after bariatric surgery and its incremental costs., Objectives: We aim to identify risk factors predicting IC after bariatric surgery and quantify its associated costs., Setting: Nationally representative sampling of acute care hospitals across the United States., Methods: A retrospective cohort study was performed using the National Readmission Database 2010 to 2014. Cox proportional hazard analyses were used to identify risk factors for IC. Linear regression models were constructed to examine associations between cholecystectomy timing and cumulative hospitalization costs., Results: An estimated national total of 553,658 patients received bariatric surgery during the study period. Of these, 3.3% received concomitant cholecystectomy (CC). After adjusting for bariatric procedure type, age, sex, complication, and length of stay, CC was independently associated with a US$1589 increase in hospitalization cost (95% confidence interval US$1021-2158, P<.01). Of patients that received no CC, only .6% underwent IC during the up to 1-year follow-up. Age<35 (P<.01), female sex (P<.01), and high preoperative body mass index (P = .03) were all risk factors for IC. IC was independently associated with a US$1499 higher cumulative hospitalization cost than CC (P<.01, 95% confidence interval US$844-2154)., Conclusions: Despite the higher absolute cost of IC, its low incidence does not financially justify a routine prophylactic CC approach. In addition, no significant reduction in cholecystectomy-related complications was achieved by performing CC. An individualized approach taking identified risk factors for IC into consideration is recommended when deciding whether to perform prophylactic CC., (Copyright © 2017. Published by Elsevier Inc.)

Necessity and validity of simultant interventions while doing restrictive bariatric operations were considered. There were analyzed the results of perioperative examination of 41 patients, in whom laparoscopic bariatric operation was performed, and 23--after simultant operations. There was established necessity for obligatory performance of simultant operations while presence of indices and according qualification of surgeons.

Short-term results of treatment and cost-effect rates were analyzed in three groups of patients undergone traditional cholecystectomy, laparoscopic cholecystectomy and cholecystectomy through minilaparotomy. It was demonstrated that frequency of complications was less after operations through laparoscopy and minilaparotomy. Traditional approach had the most costs due to more number of postoperative complications, hospital stay after surgery and more number of analgesics. Cholecystectomy through minilaparotomy is most cost-effective due to high clinical effectiveness, short hospital stay and rare complications. This procedure does not require expensive devices and can be performed with regional anesthesia only. It is concluded that minimally invasive methods of cholecystectomy must be used more widely.

Between 10% to 15% of the adult population develop gallstones. Therefore, cholecystectomy is among the most common operations in general surgery. The diagnosis of cholelithiasis depends on the patient's history, clinical findings, laboratory tests and ultrasound examination. Once diagnosis of symptomatic gallbladder disease has been confirmed, laparoscopic cholecystectomy is the treatment of choice. Its advantages in comparison with open surgery are decreased morbidity, costs and hospital stay. Open cholecystectomy is still the treatment of choice for complicated gallstone disease (i.e. cancer, Mirizzi's syndrome, severe inflammation) and in high-risk patients. In case of acute cholecystitis, early laparoscopic cholecystectomy is a safe procedure and is associated with the same benefits as for symptomatic disease.

A retrospective study of all records of patients operated on for biliary lithiasis during the years 1995, 1996 and 1997 was performed in a general hospital setting to compare the costs of management according to presentation. This study shows that acute and chronic cholecystitis have statistically significantly different costs. The reimbursement plans, base on diagnostic related groups do not take this into account. This system disadvantages those centers which preferentially treat acute pathologies.

Hypothesis: We hypothesized that complications of gallstone disease are more common than previously recognized and are related to treatment delay., Design: Retrospective review., Patients: Data for 248 consecutive patients from a university hospital in 1995-1996 and 40,571 patients identified through the 1996 California Office of Statewide Health Planning and Development database who underwent cholecystectomy for gallstone disease were reviewed., Main Outcome Measures: Diagnosis, length of hospital stay, hospital mortality, type of admission, type of surgical procedure, hospital cost, and interval of delay between onset of initial symptoms, ultrasound diagnosis, and cholecystectomy., Results: The spectrum of gallstone disease included biliary colic in 56%, acute cholecystitis in 36%, acute pancreatitis in 4%, choledocholithiasis in 3%, gallbladder cancer in 0.3%, and cholangitis in 0.2%. Community hospitals, public or county hospitals, and academic health centers had a similar distribution of diagnoses. Patients undergoing cholecystectomy for biliary colic had a significantly shorter length of hospital stay, lower operative mortality rate, were more likely to have their operations completed laparoscopically, and had lower hospital charges than patients undergoing cholecystectomy for complications such as acute cholecystitis. Over half of the patients requiring cholecystectomy for complications of gallstones initially presented with biliary colic. Patients with gallstone complications had an average delay from ultrasound confirmation to surgery of 6 months., Conclusion: Complications of gallstone disease are (1) common, (2) costly, and (3) potentially preventable.

Asymptomatic gallstones are defined as stones that have not caused biliary colics or other biliary symptoms. Some cross-sectional epidemiological screening studies have shown that as many as 66% to 77% of patients with gallstones are asymptomatic. Studies of natural history suggest that the cumulative probability of developing biliary colics after ten years ranges from 15% to 25%. None of the variables considered as possible modifiers of natural history, were found to be associated with an increased risk of incidence of biliary colics. Cholecystectomy is a vary safe treatment and is being performed with near zero mortality. Two are the possible strategies compared: prophylactic cholecystectomy with expectant management for silent gallstone disease. Consideration of survival and monetary costs disfavors prophylactic cholecystectomy. The results of laparoscopic cholecystectomy compare favorably with those of open cholecystectomy with respect to mortality, complications, length of hospital stay, cosmetically satisfactory and financial benefits. Patients with asymptomatic stones in the gallbladder require neither surgical nor medical treatment. Consideration of monetary costs disfavors prophylactic cholecystectomy: a waiting attitude has the advantage of lowering the sanitary costs also for the high incidence of silent gallstones in our population.

Objective: The aim of this study was to compare the cost of laparoscopic cholecystectomy with that of open cholecystectomy., Design: We analyzed the cost of both procedures regarding hospital stay, days of work lost and the cost derived from the morbidity of the complications of each technique in two groups of patients. With these data we were able to calculate direct and indirect costs of both procedures and compare them., Results: Morbidity was similar in both groups and had no influence in the cost; cost of the material used for laparoscopic cholecystectomy was higher; hospital stay and days of lost work were significantly lower for the laparoscopic procedure than for the open one. The total cost of laparoscopic cholecystectomy was 23% cheaper than that of open cholecystectomy., Conclusions: Laparoscopic cholecystectomy appears to be cheaper than open cholecystectomy. As the laparoscopic technique becomes more widespread its cost might decrease even further.

The authors report the results of mini-cholecystectomy performed through a 3 to 4 cm long subcostal incision in 29 patients with the diagnosis of acute or chronic cholecystitis, from February 1991 to November 1922. Some of the patients were obese, diabetics or presented as emergency cases. The patients were operated on in the morning, as in laparoscopic cholecystectomy, began oral intake in the afternoon and were discharged on the day after surgery. Dissection of the gallbladder was facilitated by the use of a modified gynecologic valve and long thin instruments. Duration of surgery varied from 40 to 140 minutes. Patients could return to work on the third day after surgery. Notably, the costs/benefits were on the third more favorable than those of laparoscopic cholecystectomy.

In order to strike the most favorable balance between health benefits and costs, three treatment modalities for symptomatic cholelithiasis were compared in a cost-effectiveness study: extracorporeal shock-wave lithotripsy (ESWL), conventional cholecystectomy (CC), and laparoscopic cholecystectomy (LC). Data were analyzed from 55 patients who were treated by ESWL, 45 patients who had CC, and 47 patients who had LC. The study was performed by analysis of patients charts and a written questionnaire. After ESWL 35% of the patients were free of stones, 23% had fragments < or = 5 mm, and 42% had fragments > 5 mm at 1-year follow-up. Persistent complaints were reported by 59% after ESWL, 11% after CC, and 14% after LC (P < 0.001). New complaints arose in 12% after ESWL, 11% after CC, and in 5% after LC (P = NS). Patient appreciation score was highest for LC and lowest for ESWL. Mean hospital stay was 2.4 days for ESWL, 10 days for CC, and 3.5 days for LC. Overall costs of treatment were: $5,066 for ESWL; $5,893 for CC; and $3,117 for LC. This study reveals that laparoscopic cholecystectomy is the most effective treatment of the large majority of patients with symptomatic cholelithiasis. ESWL should only be considered in the case of a solitary, relatively small, completely radiolucent stone.

In the UK 1 in 3 women and 1 in 5 men will at some time develop gallstones. At least two-thirds of those with gallstones have no symptoms, and most stones are detected during investigations for unrelated reasons or at necropsy. In this article we discuss the medical and surgical management of patients with gallstones.

Despite the rapid growth of laparoscopic cholecystectomy, the comparative costs of this new procedure and open cholecystectomy remain unknown. In this study the costs have been evaluated of a consecutive series of patients undergoing these procedures in a district general hospital with an established resource management centre. Fifty consecutive patients undergoing open cholecystectomy between June 1988 and July 1990 immediately before the introduction of laparoscopic cholecystectomy and 100 patients undergoing laparoscopic cholecystectomy between August 1990 and June 1992 were studied. Costs estimated prospectively for each patient were compared. The mean cost per patient of open cholecystectomy was estimated at 2102 pounds compared with 2026 pounds for the first 50 patients undergoing the laparoscopic procedure. The mean cost (1744 pounds) for the second 50 patients undergoing laparoscopic cholecystectomy was less than that for either open cholecystectomy (P < 0.005) or the initial 50 laparoscopic operations (P < 0.03). Operating theatre costs and equipment costs were higher in both laparoscopic groups. These were offset by the higher nursing and ward costs of open cholecystectomy. For the laparoscopic procedure the operating theatre times and duration of hospital stay were both less in the second 50 patients than in the first 50. After the initial learning period, laparoscopic cholecystectomy is less expensive than the open operation and represents a cost-effective method for treatment of the patient with gallstones.

The costs and effects of open versus laparoscopic cholecystectomies are compared, from the point of view of hospitals and patients, for a consecutive series of 47 patients undergoing a cholecystectomy in the University Hospital Gasthuisberg, in Belgium. For the patients the laparoscopic technique is superior, since effects are better and direct costs are lower than for the open technique. From a financial viewpoint, hospitals have to weigh the higher costs of the laparoscopic equipment against the lower variable costs due to the shorter postoperative length of stay. Total hospital costs would be lower in case all cholecystectomies were performed with the laparoscopic rather than with the open technique if at least 140 cholecystectomies are done annually with the electrocautery technique, or 300 procedures with laser. However, more recent data reveal that the operating time reduces with the number of laparoscopic procedures (learning effects), implying that the laparoscopic electrocautery procedure would already be the cheaper alternative if more than 70 cholecystectomies are done annually, if disposables are used (or if 50 procedures are done with re-usables). It can be concluded that, once sufficient experience with laparoscopy has been achieved, most hospitals could realise cost savings by switching, as much as is medically justified, to laparoscopic procedures. This will also hold for hospitals performing few cholecystectomies, as long as re-usables and electrocautery are used.

To determine the potential role of extracorporeal shock wave lithotripsy (ESWL) in the treatment of symptomatic gallstone patients in France, a simulation model evaluated the health and economic effects of three different treatment strategies. Decision analysis of conventional cholecystectomy alone and either of two strategies using a combination of biliary lithotripsy and conventional cholecystectomy reveals that a strategy employing biliary ESWL results in a significant number of successfully treated patients, thus avoiding the risks and costs of abdominal surgery. Moreover, cost analysis shows that expanding the use of lithotripsy to all patients for whom the procedure is indicated increases the average cost per successfully treated patient, but, more importantly, decreases the overall costs incurred by the cohort. From a societal viewpoint, a policy using biliary ESWL in appropriate patients is superior to one of cholecystectomy alone, from both clinical and economic perspectives.

After laparoscopic cholecystectomy (LC) has replaced open cholecystectomy (OC) to a large extent as standard method in the operative treatment of cholecystolithiasis the question of costs and economics raises. To evaluate this question the data of 50 patients who underwent elective LC were analysed in a retrospective study and compared with the data of 50 patients who were cholecystectomized using the open technique. The median of in-hospital stay was 6 (3-15) days for LC and 10 (3-33) days for OC. The median of time of working-disability was 14 (2-35) days for LC and 21 (2-56) days for OC. Total cost (median) of 3788 (2637-8101) DM for LC compared to 4509 (2041-15218) DM for OC. The median of hospital income was 2790 (1395-6975) DM for the LC-group and 4650 (1395-15346) DM for the OC-group. Due to the shorter in-hospital stay of LC-patients this method causes a microeconomical loss for the hospital compared to OC. Macroeconomically LC represents a benefit because of shorter working-disability.

One hundred elective completed laparoscopic cholecystectomies performed during the period July 1990 to June 1991 were prospectively analyzed for age, sex, and the study variables. A control group of 100 age- and sex-matched patients undergoing elective open cholecystectomy in the year prior to the advent of laparoscopic cholecystectomy was retrospectively analyzed. Both groups were comparable with regard to height, weight, severity of disease, and co-morbidity. The mean operative time for the laparoscopic cholecystectomy group was 107 min vs. 72 min for the open cholecystectomy group. Other significant differences included the use of cholangiography (24% vs. 93%), placement of drains (4% vs. 27%), and morbidity (3% vs. 7%). There was no mortality in either group. The mean length of hospital stay was 1.6 days for the laparoscopic cholecystectomy group vs. 4.8 days in the open cholecystectomy group. The resultant difference in hospital charges to the patient favored laparoscopic cholecystectomy with a mean charge of $6471 vs. $8896 for the open cholecystectomy group. The results of this study support the conclusions that laparoscopic cholecystectomy is a safe and effective alternative to open cholecystectomy and results in a significantly shorter hospital stay with considerable cost savings.

Laparoscopic cholecystectomy quickly emerged as an alternative to open cholecystectomy. However its safety, efficacy, and morbidity have yet to be fully evaluated. During the first 6 months of 1990, we performed 100 consecutive laparoscopic cholecystectomies with no deaths and a morbidity rate of 8% (8 of 100 patients; 4 major, 4 minor). There were 81 women and 19 men, with a mean age of 46.1 years (range, 17 to 84 years). All patients had a preoperative history consistent with symptomatic biliary tract disease, and most had proved gallstones by sonography. This included four patients with acute cholecystitis. Mean operating time improved significantly from month 1 to month 6 (122 +/- 45.4 minutes versus 78.5 +/- 30 minutes, respectively), indicating a rapid learning curve. Mean hospital stay was 27.6 hours, reflecting a policy of overnight stay. Postoperative narcotic requirements were limited to oral or no medications in more than 70% of patients. A regular diet was tolerated by 83% of the patients by the morning following the procedure. Median time of return to full activity was 12.8 +/- 6.8 days after operation. In addition analysis of the hospital costs of these 100 cases demonstrates a modest cost advantage over standard open cholecystectomy (n = 58) (mean, $3620.25 +/- $1005.00 versus $4251.76 +/- $988.00). There was one minor bile duct injury requiring laparotomy and t-tube insertion, two postoperative bile collections, and one clinical diagnosis of a retained stone that passed spontaneously. Four patients required conversion to open cholecystectomy because of technical difficulties with the dissection. Although there is a significant learning curve, laparoscopic cholecystectomy is a safe and effective procedure that can be performed with minimal risk. Laparoscopic cholecystectomy should be performed by surgeons who are trained in biliary surgery and knowledgeable in biliary anatomy, and, as with all operations, it should be performed with meticulous attention to technique.

Objective: Ursodeoxycholic acid (ursodiol) is an oral dissolution agent recently approved by the Food and Drug Administration for treatment of cholelithiasis. The authors conducted a cost-effectiveness analysis comparing ursodiol with elective cholecystectomy and expectant management for men and women of ages 50 and 70 with typical chronic biliary symptoms., Design: Using published literature and national cost data, the authors performed a decision analysis in which the outcome measures were life expectancy, quality-adjusted life expectancy, and expected lifetime treatment cost., Patients: The analysis applies to patients with symptoms of biliary colic, noncalcified gallstones less than 20 mm in diameter, and functioning oral cholecystograms, who are candidates for elective cholecystectomy. Excluded were patients with acute cholecystitis or known or suspected common bile duct stones., Results: Ursodiol is both clinically advantageous and less expensive than surgery for symptomatic men aged 64 or more, and for symptomatic women aged 69 or more. At ages younger than these, the clinical advantage of surgery is small and could be nullified if ursodiol were targeted at patients for whom dissolution is most likely to be effective, based on evidence of stone size and composition. Expected lifetime costs of ursodiol range from $300-400 more than surgery for 50-year-olds to $700-1,000 less than surgery for 70-year-olds. Ursodiol is the preferred choice for patients throughout this age range who are at significantly elevated risk of operative mortality., Conclusion: Ursodiol is a clinically advantageous and cost-effective alternative to elective cholecystectomy, especially for older and high-risk patients.

Over 500,000 cholecystectomies are performed each year in the United States. The procedure has its risks (mortality is 1.2% in the general population and 3% in patients aged 75 years or over) and it is expensive: the average direct cost of each cholecystectomy is about $10,000, for a national total of $5 billion annually. An alternative to surgery is to dissolve the stone with ursodiol, a naturally occurring bile acid, which has been successfully used for cholesterol gallstones with a diameter less than 20 mm. A computer model was developed to compare the costs of surgery for gallstones and treatment with ursodiol. In a hypothetical health maintenance organization with one million enrollees, use of ursodiol treatment rather than cholecystectomy would result in cumulative savings of $8.5 million after one year, $30.7 million after five years, and $57.8 million after ten years.

A medical audit was conducted in a Paris hospital on patients who, in 1975, underwent cholecystectomy for uncomplicated gallstones. The audit comprised the duration of pre- and post-operative hospitalisation, the Social Security grading of medical acts, biochemical and radiological examinations and the quality of medical care, as assessed by morbidity and mortality rates. The results were brought to the knowledge of all members of the surgical team concerned. Similar studies conducted two and five years later showed that self-restriction on the part of the physicians resulted in improved costs through shorter stays in hospital (especially before surgery) and less extensive and numerous examinations, the incidence of complications remaining the same.

Three therapeutic strategies are possible in a patient with asymptomatic or mildly symptomatic cholesterol gallstones: Cholecystectomy, medical gallstone dissolution, and expectant attitude. The course of cholelithiasis under these three strategies was evaluated by three decision trees. The incidences of possible complications were taken from the literature. For every complication the costs of drugs, absenteeism, treatment as outpatient and inpatient were listed. The costs multiplied by the likelihood of the complication represent the expected costs of the complication under consideration. The sum of the costs due to the initial treatment and the expected costs of all possible complications corresponds with the expected average costs of a therapeutic strategy. It is 21 000,- DM with medical gallstone dissolution, 25 000,- DM with immediate cholecystectomy, and 27 000,- DM with expectant attitude, respectively. Gallstone dissolution becomes more expensive than cholecystectomy only when its efficacy drops below 40%. The data show that the costs are less important for the choice of the therapy in cholelithiasis. The advantage of the decision tree lies in the fact that it describes the history and the costs of a disease by figures. Thereby, disagreement on the effects of a therapy on the course of the disease can be analysed and discussed more distinctly.
