Defining Biliary Hyperkinesia and the Role of Cholecystectomy.

Functional gallbladder disorder is most commonly defined by biliary colic and low ejection fraction (EF) on cholescintigraphy. Biliary hyperkinesia is a controversial type of functional gallbladder disorder, and its definition and the role of cholecystectomy in treating functional gallbladder disorder remains unclear. We conducted a retrospective review of patients who underwent cholecystokinin-stimulated cholescintigraphy and cholecystectomy at 3 Mayo Clinic sites between 2007 and 2020. Eligible patients were 18 years or older, presented with symptoms of biliary disease, had an EF greater than 50%, underwent cholecystectomy, and had no evidence of acute cholecystitis or cholelithiasis on imaging. We used receiver operating characteristics curve analysis to identify the optimal cutoff value that predicted symptom resolution within 30 days of cholecystectomy. A total of 2,929 cholecystokinin-stimulated cholescintigraphy scans were performed during the study period; the average EF was 67.5% and the median EF was 77%. Analyzing those with EFs greater than or equal to 50% yielded 1,596 patients with 141 (8.8%) going on to have cholecystectomy. No significant differences were found in age, sex, BMI, final pathology between patients with and without pain resolution. Using a cutoff EF of 81% was significantly associated with pain resolution after cholecystectomy (78.2% for EF greater than or equal to 81% vs 60.0% for EF less than 81%, p = 0.03). Chronic cholecystitis was found in 61.7% of the patients on final pathology. We determined that an EF cutoff of 81% is a reasonable upper limit of normal gallbladder EF. Patients with biliary symptoms and an EF greater than 81% but no evidence of biliary disease on ultrasound or scintigraphy can be classified as having biliary hyperkinesia. Based on our findings, we recommend cholecystectomy for this patient population.

Intraoperative cholangiography versus magnetic resonance cholangiography in patients with mild acute biliary pancreatitis: A prospective study in a second-level hospital.

Cholecystectomy is the only definitive management of pancreatitis secondary to gallstone disease. Approximately 20% to 30% of patients with acute biliary pancreatitis (ABP) will have persistent common bile duct (CBD) stones. Therefore, choosing a method for the early diagnosis of choledocholithiasis is essential to reduce waiting days for surgery and hospital stay in these patients.The aim of this study was to compare the use of magnetic resonance cholangiography (MRC) and intraoperative cholangiography (IOC), and its impact on the length of the hospital stay in patients with mild ABP and an intermediate probability of choledocholithiasis.We prospectively evaluated all patients diagnosed with mild ABP and an intermediate probability of choledocholithiasis at admission and 48 hours after, from June, 2017 to December, 2017. Study subjects were identified upon admission and were classified into 2 groups of patients according to their choledocholithiasis predictors; a MRC was performed in the group 1, and an IOC was done in group 2.In all, 47 patients were enrolled in the final analysis of this study. Hospital stay in group 1 (CMR) patients was 8.29 (±2.69) days compared with 6.43 (±2.57) days in the group 2 (IOC) (P = .007). Mean waiting days for cholecystectomy was 17.14 (±26.04) days for group 1 and 5 (±2.69) days for group 2.We suggest an IOC as the election method for the diagnosis of CBD stones in patients with mild ABP in medical centers similar to ours because it reduces waiting days for surgery and hospital stay compared to the MRC.

Unrecognized necrosis at same admission cholecystectomy for pancreatitis increases organ failure and infected necrosis

Background and aimsGuidelines recommend same admission cholecystectomy (SAC) in the management of mild acute gallstone pancreatitis (AGP) with a recent randomized trial supporting this recommendation. However, the push for early cholecystectomy will lead a subset of patients with evolving, unrecognized necrotizing pancreatitis (NP) to undergo laparoscopic cholecystectomy (LC) with unknown consequences. With concerns about potentially serious outcomes, we studied the outcomes in patients with unrecognized NP who underwent SAC and identified predictors of unrecognized NP at the time of SAC. MethodsRetrospective study of patients who appeared to have mild AGP but subsequently discovered to have unrecognized NP after SAC (study group). Outcomes were compared to a similar cohort with necrotizing AGP who did not undergo SAC (control group 1). Predictors for unrecognized NP at the time of SAC were identified through logistic regression using a second control group with truly mild AGP undergoing SAC. ResultsPatients in the study group (N = 46) undergoing SAC demonstrated higher rates of persistent organ failure (p = 0.0003), infected necrosis (p = 0.02), and length of hospital stay (p = 0.049) compared to a similar group (N = 48) with necrotizing AGP who did not undergo SAC. Persistent SIRS (p < 0.0001) and WBC >12 × 109/L (p < 0.0001) on the day of cholecystectomy were associated with evolving/unrecognized NP. ConclusionsUnrecognized NP at the time of SAC is associated with increased rates of subsequent persistent organ failure, infected necrosis, and length of hospital stay. Persistent leukocytosis and SIRS at the time of proposed cholecystectomy are predictive of unrecognized NP and should prompt contrast enhanced CT prior to proceeding with LC.

Surgical management of acute cholecystitis.

Acute cholecystitis occurs in approximately 1% of patients with known gallstones. It presents as a surgical emergency and usually requires hospitalisation for treatment. It is associated with significant morbidity and mortality, particularly in the elderly. Cholecystectomy is advocated for acute cholecystitis; however, the timing of cholecystectomy and the value of the additional treatments have been a matter of debate. This review examines the available evidence regarding the optimal surgical management of patients with acute cholecystitis. A literature search was performed on the MEDLINE, EMBASE and WHO International Clinical Trials Registry Platform, databases for English language publications. The MeSH headings 'cholecystitis', 'acute', 'gallbladder', 'inflammation', 'surgery', 'cholecystectomy', 'laparoscopic', 'robotic', 'telerobotic' and 'computer-assisted' were used. Data from eight randomised controlled trails and three population-based analyses show that early cholecystectomy for acute cholecystitis performed on the index admission is safe and not associated with increased conversion rates or morbidity in comparison to conservative treatment followed by elective cholecystectomy. Delaying cholecystectomy increases readmissions for gallstone-related events, complications, hospital stay and mortality in the elderly. Early cholecystectomy is also more cost-effective. Randomised trials addressing antibiotic use in acute cholecystitis suggest that antibiotics should be stopped on the day of cholecystectomy. Insufficient trials have been performed to address the optimal analgesia regime post cholecystectomy. Similarly, a lack of trials on intraoperative cholangiography and management of common bile duct stones in patients with acute cholecystitis means that treatment of concomitant bile duct stones should be based on institutional expertise and resource availability. As regards acute cholecystitis in elderly and high-risk patients, case series and retrospective studies would suggest that cholecystectomy is more effective and of lower mortality than percutaneous cholecystostomy. There is not enough evidence to support the routine use of robotic surgery, single-incision laparoscopic cholecystectomy or natural orifice transluminal endoscopic surgery (NOTES) in the treatment of acute cholecystitis. Trial evidence would favour a policy of early laparoscopic cholecystectomy following admission with acute cholecystitis. The optimal approach to support early cholecystectomy is suggested but requires evidence from further randomised trials.

Reusable single-port access device shortens operative time and reduces operative costs

In recent years, single-port laparoscopy (SPL) has become an attractive approach for performing surgical procedures. The pitfalls of this approach are technical and financial. Financial concerns are due to the increased cost of dedicated devices and prolonged operating room time. Our aim was to calculate the cost of SPL using a reusable port and instruments in order to evaluate the cost difference between this approach to SPL using the available disposable ports and standard laparoscopy. We performed 22 laparoscopic procedures via the SPL approach using a reusable single-port access system and reusable laparoscopic instruments. These included 17 cholecystectomies and five other procedures. Operative time, postoperative length of stay (LOS) and complications were prospectively recorded and were compared with similar data from our SPL database. Student's t test was used for statistical analysis. SPL was successfully performed in all cases. Mean operative time for cholecystectomy was 72 min (range 40-116). Postoperative LOS was not changed from our standard protocols and was 1.1 days for cholecystectomy. The postoperative course was within normal limits for all patients and perioperative morbidity was recorded. Both operative time and length of hospital stay were shorter for the 17 patients who underwent cholecystectomy using a reusable port than for the matched previous 17 SPL cholecystectomies we performed (p < 0.001). Prices of disposable SPL instruments and multiport access devices as well as extraction bags from different manufacturers were used to calculate the cost difference. Operating with a reusable port ended up with an average cost savings of US$388 compared with using disposable ports, and US$240 compared with standard laparoscopy. Single-port laparoscopic surgery is a technically challenging and expensive surgical approach. Financial concerns among others have been advocated against this approach; however, we demonstrate herein that using a reusable port and instruments reduces operative time and overall operative costs, even beyond the cost of standard laparoscopy.

Index cholecystectomy for management of acute gallstone disease: a change of practice at a major New Zealand metropolitan centre

ObjectivesThis study aimed to examine the effects of a change in practice in index cholecystectomy on waiting lists at a New Zealand metropolitan hospital. MethodsPatients presenting with gallstone disease from January 2004 to October 2010 were identified. Data on acute and elective cholecystectomies were collated and analysed for length of stay. Waiting lists for cholecystectomy were compared. ResultsDuring the study period, 3999 patients were admitted with acute gallbladder disease. The median number of admissions decreased from 49 to 40 per month (P < 0.01). The median number of index cholecystectomies increased from three to 22 per month (P < 0.01). Total monthly bed days for all cholecystectomies decreased from 175 days to 124 days (P < 0.01), but only median postoperative bed days for acute cholecystectomy showed a similar trend, decreasing from 4 days to 3 days (P < 0.01). The number of patients on the waiting list decreased from 334 in January 2004 to 132 in January 2006 as a result of government-imposed cuts. The number of patients wait-listed for elective cholecystectomy remained unchanged. ConclusionsAn increasing number of index cholecystectomies have been performed at this centre. An effect on waiting list numbers is yet to be shown, but the wait list has not ballooned to previous numbers, although the number of patients joining the wait list remains unchanged. Monthly bed days have decreased for all patients with acute gallstone disease, probably in response to a combination of the changes implemented.

Organ system dysfunction following open cholecystectomy for acute acalculous cholecystitis in critically ill patients

Acute acalculous cholecystitis (AAC) refers to cholecystitis without gallstones and is a serious complication of critical illness. We describe the time course of organ system dysfunction associated with cholecystectomy in critically ill patients with AAC. The data of all intensive care unit (ICU) patients who had operatively confirmed AAC during their ICU stay between 2003 and 2004 were analyzed. Patients who also had other intra-abdominal pathologies were excluded. The Sequential Organ Failure Assessment (SOFA) scores were recorded 3 days before, on the day of operation and on the first, second, third and seventh post-operative day after cholecystectomy. The impact of open cholecystectomy on organ dysfunction was evaluated on the basis of the change in the total and individual organ SOFA scores. Twenty-four patients underwent open cholecystectomy for AAC with no other intra-abdominal pathology. Sepsis was the most common admission diagnosis, followed by cardiovascular surgery. The mean (standard deviation, SD) Acute Physiology and Chronic Health Evaluation (APACHE II), Simplified Acute Physiology Score (SAPS) II and SOFA scores on admission were 24.7 (5.8), 44.3 (12.3) and 9.4 (3.2), respectively. The median (25th, 75th percentiles) total SOFA score 3 days before cholecystectomy was 7.5 (1.3, 8.0), which increased to 10.5 (8.3, 13.0) (P < 0.0001) by the day of cholecystectomy, indicating developing multiorgan dysfunction. After the operation, the score decreased to 5.5 (3.3, 10.8) (P = 0.004) by the seventh post-operative day. The change was most obvious in cardiovascular and respiratory SOFA scores. AAC is associated with multiorgan dysfunction in critically ill patients. Open cholecystectomy seems to alter the course of multiorgan dysfunction in these patients.

Mortality after open cholecystectomy in patients with cirrhosis of the liver: a population-based study in Denmark.

To find out if patients with alcoholic cirrhosis are at greater risk of dying within 30 days of cholecystectomy than patients with non-alcoholic cirrhosis or normal controls. Population-based study. Hospitals, Denmark. 23103 patients with liver cirrhosis recorded in the Danish National Registry during the period 1977-94, of whom 110 had an open cholecystectomy; a random sample of 1204 patients without cirrhosis taken from all patients who had a cholecystectomy during the study period. Risk of mortality. In the group with alcoholic cirrhosis the 30-day mortality was 7.7% and for the controls it was 0.9%. In patients with alcoholic cirrhosis the relative risk of death within 30 days was 11.5 (95% confidence interval 2.8 to 47.4) compared with controls, whereas that for patients with non-alcoholic cirrhosis was 1.1 (95% CI 0.1 to 9.8) compared with controls. Patients with alcoholic cirrhosis have an 11-fold increased risk of postoperative mortality after undergoing cholecystectomy.

Outpatient Laparoscopic Cholecystectomy in Hong Kong

The authors performed a prospective evaluation of 60 Hong Kong Chinese patients with symptomatic gallstones and gallbladder polyps undergoing outpatient laparoscopic cholecystectomy in a regional hospital in Hong Kong from March 1996 to May 1998 to determine the feasibility, satisfaction, and acceptance of this procedure among Chinese patients. Patients with American Society of Anesthesiologists grade I and II gallstones or polyps were selected. Exclusion criteria included 1) history of upper abdominal operations, attacks of acute cholecystitis, cholangitis, or pancreatitis; 2) abnormal liver function; and 3) ultrasonographic evidence of contracted gallbladder, thickened gallbladder wall, dilated common bile duct, or common bile duct stones. Patients discharged at 5:00 PM on the day of cholecystectomy were defined as having undergone outpatient procedure. Patients were asked about procedure acceptance, rated on a scale of 1 to 10 (best), using a standardized questionnaire 4 weeks after operation. The study included 21 men and 39 women with mean age of 40.5 years (range, 27-59). There were no conversions to open procedures in the series. There were 6 (10%) unanticipated postoperative hospital admissions; all patients were discharged on the first postoperative day. Another patient was readmitted 3 days after operation because of a common bile duct stone. Overall patient acceptance of outpatient laparoscopic cholecystectomy was good, with a mean score of 8.6 of 10. Thirteen patients (22%) expressed dissatisfaction with being discharged earlier than they had expected, and 9 (15%) would have preferred inpatient care. Forty-eight patients (80%) resumed full daily activities by the first postoperative day; the remaining 12 did so by the end of the first week. Among the 44 working patients, only 4 (9%) resumed full duty within the first postoperative week; 29 (66%) did so by the second week and the remaining 11 (25%) returned to work after the third week. By selecting appropriate subjects, outpatient laparoscopic cholecystectomy is feasible and highly accepted among Hong Kong Chinese patients. Approximately one quarter of the patients preferred a longer postoperative stay or inpatient care.

Short surgical stay: Two hospital days for cholecystectomy

One hundred consecutive patients undergoing cholecystectomy by the standard operative technique were managed according to five cost-efficiency principles. Ileus did not occur, and patients routinely ate a regular diet on the evening of the first postoperative day. Oral analgesics adequately controlled incision pain. The preoperative day in the hospital was eliminated in the latter part of the study. With careful preoperative and postoperative patient instruction, the majority of patients were satisfied with their stay and no readmissions were necessary. In short, the feasibility and safety of admission 2 hours before and discharge 2 days after elective cholecystectomy have been documented herein.
