National analysis of in-hospital resource utilization in choledocholithiasis management using propensity scores.

BACKGROUND: Two treatment options exist for choledocholithiasis (CDL): endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct exploration (CBDE). Resource utilization measured by total in-hospital charges (THC) and length of stay (LOS) was compared using the propensity score (PS). In this study, PS was the probability that a patient received CBDE based on comorbidities and demographics. The power of this method lies in balancing groups on variables by PS, resulting in 90% bias reduction and improved inferential validity compared to traditional analytic techniques. METHODS: Laparoscopic cholecystectomy (LC) patients with CDL who had ERCP or CBDE were identified in the 2002 U.S. Nationwide Inpatient Sample. Patients were ordered into five PS balanced strata. Mean THC, LOS, and estimated costs were compared. A linear regression model was used to estimate the contribution that LOS had on estimated costs. Monetary values were adjusted to 2004 dollars. RESULTS: A total of 40,982 patients underwent LC with CDL in 2002; 27,739 had either ERCP (93%) or CBDE (7%). Mean age was 52.7 +/- 0.4 years, with 74% women. Mean THC were less for CBDE (25,200 dollars +/- 1,800 dollars) than for ERCP (29,900 dollars +/- 800 dollars, p < 0.05). Mean LOS was less for CBDE (4.9 +/- 0.2 days) than for ERCP (5.6 +/- 0.1 days, p < 0.05). PS adjusted analysis revealed an estimated overall cost savings of 4,500 dollars +/- 1,600 dollars and reduced LOS (0.6 +/- 0.2 days) per hospitalization for CBDE. Mean THC, LOS, and estimated costs across PS score balanced strata were generally higher in the ERCP group compared to the CBDE group. LOS contributed 53% to increased THC and 62% of estimated costs. A higher cumulative incidence of complications was evident with CBDE (0.5-4.6%) compared to ERCP (0.3-3.6%). CONCLUSIONS: Based on this PS analysis, CBDE incurs less THC, reduces LOS, and has less estimated costs for CDL compared to ERCP. Furthermore, CBDE appears to be dramatically underutilized.

Routine laparoscopic cholecystectomy after endoscopic sphincterotomy for choledocholithiasis in octogenarians: is it worth the risk?

BACKGROUND: No unanimous consensus has been reached as to the need for routine laparoscopic cholecystectomy (LC) after endoscopic sphincterotomy (ES) for choledocholithiasis in very elderly patients, who are considered as high-risk subjects for surgery. METHODS: From 1991 through 1997, 170 patients were referred to undergo preoperative ES and routine LC for common bile duct (CBD) stones. The results for 27 patients (age 80 years or older) were compared with those achieved for younger patients. Successively, in a retrospective case-control study, the results for the selected patients were compared with those for 27 very elderly patients who underwent endoscopic retrograde cholangiopancreatography (ERCP), but did not receive LC. The mean follow-up period was 126 months. RESULTS: Octogenarians showed longer surgery time (79 vs 51 min) and postoperative hospital stay (2.8 vs 1.2 days), as well as more early low-grade complications (15% vs 3%), whereas there were no differences in conversion rate or serious complications. Recurrent symptoms or complications developed in 48% of octogenarians not undergoing routine LC, and 30% finally needed surgery. One patient in the control group died after emergency cholecystectomy for acute cholecystitis. The results of surgery were significantly poorer for the control group. CONCLUSIONS: Although a "wait-and-see" policy allowed two-thirds of LCs to be avoided in octogenarians, biliary-related events developed for every second patient, often requiring delayed surgery, with poorer results. Sequential treatment (ES followed by elective LC) is a safe procedure for octogenarians, and should be considered as a standard, definitive treatment for cholecystocholedocholithiasis even after the age of 80 years.

Endoscopic sphincterotomy in adult hemophiliac patients with choledocholithiasis.

BACKGROUND: The aim of this study was to investigate the risk of bleeding in adult hemophiliac patients undergoing endoscopic sphincterotomy for choledocholithiasis. METHODS: From 1983 to 2002, 7 patients with hemophilia A and two with hemophilia B were referred for endoscopic sphincterotomy and extraction of bile duct stones. The degree of hemophilia was mild in 4 patients, moderate in 3, and severe in two. Pre-admission levels of blood clotting factors ranged from less than 1% to 18%. Levels of the deficient factors were monitored carefully before and after sphincterotomy, and the relevant factor was replaced to achieve 100% activity before and for 24 hours after endoscopic sphincterotomy. OBSERVATIONS: Seven patients had factor replacement every 8 hours, and two received continuous infusions. No patient developed bleeding after sphincterotomy. At discharge, 48 hours after the procedure, patients who had received continuous infusions had a factor level of greater than 90%; those who had received intermittent replacement had levels of greater than 50%. After discharge, the patients were treated with regular infusion of the deficient factor for 15 days. CONCLUSIONS: With adequate preoperative and post-procedure monitoring of clotting factors, meticulous attention to hemostasis during sphincterotomy, careful post-procedure monitoring, and timely replacement therapy, patients with hemophilia can undergo endoscopic sphincterotomy without bleeding complications.

[Dilatation of the papilla of Vater in the treatment of choledocholithiasis in selected patients].

OBJECTIVE: To prospectively analyze the results obtained with papillary balloon dilatation (PBD) in the treatment of common bile duct stones in patients at risk of complications if endoscopic sphincterotomy (ES) were performed. PATIENTS AND METHOD: Thirty-three patients were included between January 2001 and June 2003 (mean age 76.2 years). The criteria for PBD were: choledocholithiasis < or =10 mm in patients with peripapillary diverticula, hemostatic alterations, Billroth-II, and preservation of Oddi's sphincter. In 79% of the patients sedation was performed by an anesthetist. PBD was performed with a balloon catheter dilator with a diameter of 8 or 10 mm for 2 minutes. The efficacy and duration of the procedure as well as complications at 30 days and patient satisfaction were evaluated. RESULTS: Stone extraction was achieved in all patients (100%). The mean duration of the procedure was 26 minutes. Two patients (6%) presented mild pancreatitis. Serum amylase was elevated in 16 patients (48%): > or =3 times (post-PBD hyperamylasemia) in 11 (33%). The procedure caused no discomfort in 25/26 (96%) of the patients sedated by an anesthetist vs 2/5 patients (49%) who underwent endoscopic sedation. CONCLUSIONS: PBD is an effective and simple therapeutic option in the treatment of small common bile duct stones (< or =10 mm) and in patients at high risk. The duration of endoscopic retrograde cholangiopancreatography is not prolonged. Complications are infrequent (6%) and mild. Post-PBD hyperamylasemia is frequent and generally without clinical importance. Sedation by an anesthetist improves patient satisfaction.

Sludge ball, pseudolithiasis, cholelithiasis and choledocholithiasis from intrauterine life to 2 years: a 13-year follow-up.

OBJECTIVE: Evaluation and follow-up of infants with cholelithiasis and pseudolithiasis in a pediatric ward. PATIENTS & METHODS: Prospective study from April 1990 to October 2003 identified hospitalized infants younger than 2 years with ultrasonographic findings of cholelithiasis, choledocholithiasis or pseudolithiasis. Associated abnormalities or contributory factors were recorded and patients were followed for from 6 months to 13 years (mean, 4 years). RESULTS: Thirty-four patients were diagnosed between the age of 3 weeks and 24 months. Thirteen (38%) had been treated with third-generation cephalosporins. Other associated factors were dehydration in 10 (29%), urinary tract infection in two (6%) and one each for cholestatic liver disease, total parenteral nutrition, immunoglobulin A deficiency and prematurity. Six infants (17%) had no known risk factor. Six additional patients were diagnosed by antenatal ultrasound. CONCLUSIONS: Cholelithiasis in infants hospitalized for a variety of common pediatric conditions is not rare. Dehydration and treatment with third-generation cephalosporins are important associated factors. The classic risk factors of hemolysis and previous gastrointestinal surgery, were not found in our group. The overall prognosis was good. Pseudolithiasis disappeared in all infants. Of the 21 infants with cholelithiasis, only two developed cholecystitis. In nine infants, spontaneous resolution occurred. In the absence of other clinical or imaging evidence of biliary tract disease, conservative management is advised.

Severe INR elevation in a patient with choledocholithiasis receiving cefoperazone.

Cefoperazone is a third-generation cefalosporin that contains the N-methyl- thio-tetrazole (NMTT) side chain, which inhibits vitamin K-dependent carboxylation. Administration of NMTT-containing cefalosporins can cause alterations in the hepatic glutathione redox state, resulting in a dose-related increase in oxidised glutathione, which is responsible for the inhibition of microsomal reduction of vitamin K epoxide. In addition, cefoperazone is not metabolised and is excreted predominantly through the bile. In patients with hepatic impairment, the clearance of cefoperazone has been shown to be significantly reduced and the half-life prolonged. We report a case of choledocholithiasis related to a prolonged prothrombin time and INR secondary to cefoperazone therapy.

Safety advantage of endocut mode over endoscopic sphincterotomy for choledocholithiasis.

AIM: To evaluate whether an automatically controlled cut system (endocut mode) could reduce the complication rate of endoscopic sphincterotomy (EST) and serum hyperamylasemia after EST compared to the conventional blended cut mode. METHODS: From January 2001 to October 2003, 134 patients with choledocholithiasis were assigned to either endocut mode group or conventional blended cut mode group at the time of sphincterotomy. The two groups were retrospectively compared for the complications after EST and serum amylase level before and 24 h after the procedure. RESULTS: Of the 134 patients treated, 79 were assigned to conventional blended cut mode group and 55 to endocut mode group. There was no significant difference in age, sex, and serum amylase level before EST between the two groups. Complications were found in 5 patients of the endocut mode group (9%): hyperamylasemia (5 times higher than normal) in 4 and moderate pancreatitis in 1. Complications were found in 13 patients of the conventional blended cut mode group (16%): hyperamylasemia in 12 and moderate pancreatitis in 1. Serum amylase levels were elevated in both groups 24 h after EST (P<0.02). The average serum amylase level 24 h after EST in the conventional blended cut mode group was significantly higher than that in the endocut mode group (P<0.05). CONCLUSION: Endocut mode offers a safety advantage over conventional blended cut mode for pancreatitis after EST by reducing hyperamylasemia.

[Reduction of severity of endogenous intoxication in patients with choledocholithiasis under the influence of the probe enteral nutrition].

Results of study of the endogenous intoxication severity (EI) in 107 patients for choledocholithiasis (CL) were presented. In complex of treatment the probe enteral nutrition (PEN) was applied. Diagnosis of EI according to cellular indexes of intoxication and the peptides level of the average molecular mass (PAMM) in blood for wavelengths 254 and 280 nm was conducted. There was established, that leukocytic index of intoxication, calculated according to formula Himich-Kostyuchenko, have strong correlational causation with index of PAMM and may be applied for diagnosis and control of efficacy of the EI correction in patients with CL. PEN with application of oligopeptide mixture "Peptamen" (Nestle) had promoted effective correction of EI, what have allowed to lower frequency of postoperative complications by 11% and to shorten the treatment duration of patients after operation by 4 days.

[Diagnostic and therapeutic management of choledocholithiasis associated with gallstone disease: nine years' experience].

Different approaches are described in the literature for the detection and treatment of common bile duct stones in patients undergoing laparoscopic cholecystectomy (pre-, intra- or postoperative treatment; combined endoscopic and laparoscopic or total laparoscopic management). No particular "gold standard" treatment can be identified, since too many variables and too many techniques need to be compared. Since it is impossible to establish any single protocol, the reviewing of different large experiences is useful to identify the pros and cons of each procedure. We present the evolution of our own experience over the period 1991-2000 in 1741 patients treated by laparoscopic cholecystectomy for gallbladder stones. We have chosen to assess and treat patients with symptomatic common bile duct stones preoperatively, whereas in the asymptomatic cases we have adopted a protocol that has been modified over the years, consisting first in routine intravenous cholangiography and then in the use of a scoring system which, with the aid of ultrasound data, has allowed us to assess the risk of choledocholithiasis and to administer selective preoperative treatment for common bile duct stones.

Surgical approaches to postcholecystectomy choledocholithiasis.

One hundred sixteen cases if postcholecystectomy choledocholithiasis were assessed after different methods of surgical approach. The evidence that previous surgery, advanced age, and long history of symptoms are associated with a high incidence of bile infection and with advanced histological changes in the biliary ductal apparatus was considered as an index of biliary stasis. It is for these patients that a drainage procedure supplementary to choledochotomy was thought to be warranted. Both choledochoduodenostomy and sphincteroplasty were carried out in this series of patients as drainage procedures supplementary to choledochotomy. Choledochoduodenostomy appears to offer a definitive solution to this problem, and it has been shown to be safe and simple to carry out without mortality and with a very low morbidity.

Transduodenal papillostomy as a routine procedure in managing choledocholithiasis.

The purpose of this study was to evaluate the results of transduodenal papillostomy as a routine procedure in managing choledocholithiasis in treating common bile duct (CBD) stones. From 1973 to 1978, 117 patients underwent transduodenal papillostomy for CBD lithiasis. The operation was carried out in standard manner, and all patients had preoperative telecholangioscopy, cholangiography, and biliary manometry. The mean age of patients was 53.7 years, and women predominated in a ratio of 4.5:1.0. Papillostomy was performed together with cholecystectomy for CBD stones in 111 patients (group 1). In five patients, we had to perform a choledochotomy to remove the stones after an unsuccessful papillostomy (group 2). Eight patients who previously had cholecystectomies underwent papillostomy for retained or recurrent stones (group 3), and three patients had a choledochoduodenostomy for recurrent stones after a previous cholecystectomy and papillostomy (group 4). Complications included two deaths in group 1 (1.9%). No mortality was observed in groups 2 and 4. Moreover, the overall morbidity was due to six cases of wound infection, one case of postoperative bleeding, one case of phlebitis, and three cases of cholangitis. The mean length of hospital stay was 12.9 days, considering all the groups. Lack of confidence with this procedure may explain the different results reported in the literature for transduodenal papillostomy, which on the basis of this study has been shown to ba a valid alternative to supraduodenal choledochotomy in treating CBD stones.

Treatment of acute cholangitis due to choledocholithiasis in elderly and younger patients.

OBJECTIVE: To evaluate management strategies for acute cholangitis in elderly patients (age, > or = 80 years). DESIGN: Nonrandomized control trial. SETTING: A university hospital. PATIENTS: Patients (n = 191) who underwent urgent biliary drainage for acute cholangitis due to choledocholithiasis. Thirty-seven patients were elderly, and 154 were younger (age, < 80 years). INTERVENTIONS: Surgical (8 elderly and 48 younger patients), percutaneous transhepatic (11 elderly and 47 younger patients), or endoscopic drainage (18 elderly and 59 younger patients). MAIN OUTCOME MEASURES: Clinical features of acute cholangitis and outcomes of biliary drainage. RESULTS: The elderly patients had higher incidences of septic shock or mental confusion (acute severe cholangitis)(43.2%) and concomitant diseases (81.1%) than the younger patients (25.3% and 42.9%, respectively). The elderly patients had significantly greater morbidity (37.8%) and mortality (10.8%), compared with the younger patients (16.9% and 3.2%, respectively). Mortality was 18.8% in elderly patients with severe cholangitis and 4.8% in those with nonsevere cholangitis. In the elderly patients, endoscopic drainage yielded lower morbidity (16.7%) and mortality (5.6%) than surgical (87.5% and 25.0%, respectively) and percutaneous drainage (36.4% and 9.1%, respectively). No complications occurred after endoscopic nasobiliary drainage without sphincterotomy. CONCLUSIONS: Elderly patients with acute cholangitis have high incidence of severe disease and concomitant medical problems. They should undergo endoscopic biliary drainage, especially nasobiliary drainage without sphincterotomy, because of its safety and effectiveness.

Side-to-side choledochoduodenostomy in the management of choledocholithiasis.

Sixty patients with choledocholithiasis (either single or multiple stones of the biliary tree) were treated with lateral choledochoduodenostomy. Of these cases 83.3% were followed up for from 1 to 7 years. Only 1 patient developed cholangitis, which responded well to conservative treatment. The other cases have been asymptomatic following surgery. The diameter of the common bile duct is not an important problem in constructing a functional anastomosis.
