ABSTRACT
BACKGROUND & AIMS: Greater availability of less invasive biliary imaging to rule out choledocholithiasis should reduce the need for diagnostic endoscopic retrograde cholangiopancreatography (ERCP) in patients who have a remote history of cholecystectomy. The primary aims were to determine the incidence, characteristics, and outcomes of individuals who undergo first-time ERCP >1 year after cholecystectomy (late-ERCP). METHODS: Data from a commercial insurance claim database (Optum Clinformatics) identified 583,712 adults who underwent cholecystectomy, 4274 of whom underwent late-ERCP, defined as first-time ERCP for nonmalignant indications >1 year after cholecystectomy. Outcomes were exposure and temporal trends in late-ERCP, biliary imaging utilization, and post-ERCP outcomes. Multivariable logistic regression was used to examine patient characteristics associated with undergoing late-ERCP. RESULTS: Despite a temporal increase in the use of noninvasive biliary imaging (35.9% in 2004 to 65.6% in 2021; P < .001), the rate of late-ERCP increased 8-fold (0.5-4.2/1000 person-years from 2005 to 2021; P < .001). Although only 44% of patients who underwent late-ERCP had gallstone removal, there were high rates of post-ERCP pancreatitis (7.1%), hospitalization (13.1%), and new chronic opioid use (9.7%). Factors associated with late-ERCP included concomitant disorder of gut-brain interaction (odds ratio [OR], 6.48; 95% confidence interval [CI], 5.88-6.91) and metabolic dysfunction steatotic liver disease (OR, 3.27; 95% CI, 2.79-3.55) along with use of anxiolytic (OR, 3.45; 95% CI, 3.19-3.58), antispasmodic (OR, 1.60; 95% CI, 1.53-1.72), and chronic opioids (OR, 6.24; 95% CI, 5.79-6.52). CONCLUSIONS: The rate of late-ERCP postcholecystectomy is increasing significantly, particularly in patients with comorbidities associated with disorder of gut-brain interaction and mimickers of choledocholithiasis. Late-ERCPs are associated with disproportionately higher rates of adverse events, including initiation of chronic opioid use.

INTRODUCTION: Literature shows failure of the outpatient clinic (OC) pathway after emergency department (ED) ultrasound diagnosis of symptomatic cholelithiasis (SC). We hypothesized SC to be more prevalent on final surgical pathology (FSP) in patients who successfully completed OC pathway. METHODS: This retrospective single-institution chart review compared OC and ED patients with right upper quadrant (RUQ) pain and cholelithiasis whom underwent cholecystectomy. Clinical evaluation was considered positive if RUQ pain >4 h, or + Murphy's sign. Ultrasound was positive if two of these three were present: sonographic Murphy's, wall thickness > 4 mm, or pericholecystic fluid. Results were compared with FSP. RESULTS: Six hundred-seven patients underwent cholecystectomy, 299 OC and 308 ED. OC was more likely to SC (23% versus 4.6%) (P < 0.0001) and ED acute cholecystitis (39.3% versus 4.7%). Chronic cholecystitis was the most common FSP in both OC (72%) and ED (56%) populations, of these, 73% of OC denied pain >4 h versus only 10% of ED (P < 0.001). Median time from evaluation to cholecystectomy was 14 d versus 14 h in the OC and ED respectively (P < 0.0001). CONCLUSIONS: While chronic cholecystitis was the most common FSP in both OC and ED, the majority of OC reported RUQ pain <4 h delineating these presentations. Duration of pain should be utilized as algorithm triage. We recommend patients with pain episode <4 h should complete OC algorithm with expedited cholecystectomy within 14 d.

BACKGROUND: Adult patients with biliary acute pancreatitis (BAP) or choledocholithiasis who do not undergo cholecystectomy on index admission have worse outcomes. Given the paucity of data on the impact of cholecystectomy during index hospitalization in children, we examined readmission rates among pediatric patients with BAP or choledocholithiasis who underwent index cholecystectomy versus those who did not. METHODS: Retrospective study of children (< 18 years old) admitted with BAP, without infection or necrosis (ICD-10 K85.10), or choledocholithiasis (K80.3x-K80.7x) using the 2018 National Readmission Database (NRD). Exclusion criteria were necrotizing pancreatitis with or without infected necrosis and death during index admission. Multivariable logistic regression was performed to identify factors associated with 30-day readmission. RESULTS: In 2018, 1122 children were admitted for index BAP (n = 377, 33.6%) or choledocholithiasis (n = 745, 66.4%). Mean age at admission was 13 (SD 4.2) years; most patients were female (n = 792, 70.6%). Index cholecystectomy was performed in 663 (59.1%) of cases. Thirty-day readmission rate was 10.9% in patients who underwent cholecystectomy during that index admission and 48.8% in those who did not (p < 0.001). In multivariable analysis, patients who underwent index cholecystectomy had lower odds of 30-day readmission than those who did not (OR 0.16, 95% CI 0.11-0.24, p < 0.001). CONCLUSIONS: Index cholecystectomy was performed in only 59% of pediatric patients admitted with BAP or choledocholithiasis but was associated with 84% decreased odds of readmission within 30 days. Current guidelines should be updated to reflect these findings, and future studies should evaluate barriers to index cholecystectomy.

BACKGROUND: Acute calculous cholecystitis (ACC) is frequently seen in cirrhotics, with some being poor candidates for initial cholecystectomy. Instead, these patients may undergo percutaneous cholecystostomy tube (PCT) placement. We studied the healthcare utilization and predictors of cholecystectomy and PCT in patients with ACC. METHODS: The National Database was queried to study all cirrhotics and non-cirrhotics with ACC between 2010-2014 who underwent initial PCT (with or without follow-up cholecystectomy) or cholecystectomy. Cirrhotic patients were divided into compensated and decompensated cirrhosis. Independent predictors and outcomes of initial PCT and failure to undergo subsequent cholecystectomy were studied. RESULTS: Out of 919 189 patients with ACC, 13 283 (1.4%) had cirrhosis. Among cirrhotics, cholecystectomy was performed in 12 790 (96.3%) and PCT in the remaining 493 (3.7%). PCT was more frequent in cirrhotics (3.7%) than in non-cirrhotics (1.4%). Multivariate analyses showed increased early readmissions [odds ratio (OR) = 2.12, 95% confidence interval (CI): 1.43-3.13, P < 0.001], length of stay (effect ratio = 1.39, 95% CI: 1.20-1.61, P < 0.001), calendar-year hospital cost (effect ratio = 1.34, 95% CI: 1.28-1.39, P < 0.001) and calendar-year mortality (hazard ratio = 1.89, 95% CI: 1.07-3.29, P = 0.030) in cirrhotics undergoing initial PCT compared to cholecystectomy. Decompensated cirrhosis (OR = 2.25, 95% CI: 1.67-3.03, P < 0.001) had the highest odds of getting initial PCT. Cirrhosis, regardless of compensated (OR = 0.56, 95% CI: 0.34-0.90, P = 0.020) or decompensated (OR = 0.28, 95% CI: 0.14-0.59, P < 0.001), reduced the chances of getting a subsequent cholecystectomy. CONCLUSIONS: Cirrhotic patients undergo fewer cholecystectomy incurring initial PCT instead. Moreover, the rates of follow-up cholecystectomy are lower in cirrhotics. Increased healthcare utilization is seen with initial PCT amongst cirrhotic patients. This situation reflects suboptimal management of ACC in cirrhotics and a call for action.

BACKGROUND: The extent of resection required in advanced gallbladder cancer is controversial. We aimed to describe the management and outcomes in patients with resected stage T2 and T3 gallbladder cancer. METHODS: In this population-based study, all T2 and T3 gallbladder cancer cases from Jan. 1, 2002, to Mar. 31, 2012, were identified from the Ontario Cancer Registry; pathology reports were linked and abstracted. The type of resection was classified as extended (cholecystectomy + liver resection, with or without bile duct resection) or simple (cholecystectomy only). We used Kaplan-Meier survival analysis to model time to death and evaluated factors associated with overall survival using the Cox proportional hazards regression model. RESULTS: A total of 370 patients were included, 232 with T2 disease and 138 with T3 disease. The proportions who underwent extended resection were 24.1% (56/232) and 37.0% (51/138), respectively. The unadjusted 5-year overall survival rates for simple and extended resection were 39.7% and 49.5%, respectively, for T2 disease (p = 0.03), and 13.5% and 22.8%, respectively, for T3 disease (p = 0.05). In adjusted analysis, extended resection significantly improved overall survival among patients with T2 disease (hazard ratio [HR] 0.51, 95% confidence interval [CI] 0.30-0.97), whereas higher grade of differentiation, presence of lymphovascular invasion and positive lymph nodes led to worse survival. Extended resection was not associated with improved survival in the T3 group; however, in subgroup analysis stratified by lymph node status, a trend toward improved overall survival with extended resection was seen in node-negative patients (HR 0.20, 95% CI 0.03-1.06). CONCLUSION: Extended resection improved overall survival in T2 disease regardless of nodal status but appeared most beneficial in node-negative T3 disease. The finding that extended resection was offered only to a small proportion of eligible patients highlights the need for improved knowledge translation at national surgical meetings.

INTRODUCTION: Endoscopic ultrasound (EUS) is a more sensitive technique than transabdominal ultrasound for the diagnosis of gallstones. This greater sensitivity, especially in the diagnosis of microlithiasis/biliary sludge, facilitates the indication of cholecystectomy in patients with symptoms of probable biliary origin but may result in over-indication of this surgery. OBJECTIVES: Evaluate the role of EUS in the diagnosis of minilithiasis/biliary sludge in patients with digestive symptoms of probable biliary origin by resolving the symptoms after cholecystectomy. Analyse factors related to the remission of symptoms following cholecystectomy. PATIENTS AND METHODS: Retrospective, longitudinal, single-centre study based on a prospective database of 1.121 patients undergoing EUS. Seventy-four patients were identified as meeting inclusion-exclusion criteria (diagnosed with minilithiasis/sludge by EUS after presenting digestive symptoms of probable biliary origin without a history of complicated cholelithiasis). A telephone questionnaire for symptoms was conducted with cholecystectomized patients. Factors related to a good response were analysed with logistic regression analysis. RESULTS: Of the 74 patients, 50 were cholecystectomized (67.5%), mean age 49 years (SEM 2.26) (41 women). Seventy percent of patients (35/50) presented remission of symptoms with median follow-up 353.5 days (95% CI, 270-632.2). The only variable associated with remission of symptoms was the presence of typical biliary colic with an OR of 7.8 (95% CI, 1.8-34; p=0.006). No complications associated with EUS were recorded. One patient (2%) suffered haemoperitoneum and 18% (9/50) suffered diarrhoea following cholecystectomy. CONCLUSIONS: EUS is a very useful technique for the indication of cholecystectomy in patients with minilithiasis/sludge and typical symptoms of biliary colic.

BACKGROUND: Gallbladder disease frequently requires emergency general surgery (EGS). The Affordable Care Act (ACA) mandated health insurance coverage for all with the intent to improve access to care and decrease morbidity, mortality, and costs. We hypothesize that after the ACA open-enrollment in 2014 the number of EGS cholecystectomies decreased as access to care improved with a shift in EGS cholecystectomies to teaching institutions. METHODS: A retrospective review of the National Inpatient Sample Database from 2012 to quarter 3 of 2015 was performed. Patients age 18-64, with a nonelective admission for gallbladder disease based on ICD-9 codes, were collected. Outcomes measured included cholecystectomy, complications, mortality, and wage index-adjusted costs. The effect of the ACA was determined by comparing preACA to postACA years. RESULTS: 189,023 patients were identified. In the postACA period the payer distribution for admissions decreased for Self-pay (19.3% to 13.6%, P < 0.001), Medicaid increased (26.3% to 34.0%, P < 0.001) and Private insurance was unchanged (48.6% to 48.7%, P = 0.946). PostACA, admissions to teaching hospitals increased across all payer types, EGS cholecystectomies decreased, while complications increased, and mortality was unchanged. Median costs increased significantly for Medicaid and Private insurance while Self-pay was unchanged. Based on adjusted DID analyses for Insured compared to Self-pay patients, EGS cholecystectomies decreased (-2.7% versus -1.21%, P = 0.033) and median cost increased more rapidly (+$625 versus +$166, P = 0.017). CONCLUSIONS: The ACA has changed EGS, shifting the majority of patients to teaching institutions despite insurance type and decreasing the need for EGS cholecystectomy. The trend toward higher complication rate with increased overall cost requires attention.

BACKGROUND: Inpatient cholecystectomy is associated with higher cost and morbidity relative to ambulatory cholecystectomy, yet the latter may be underutilized by minority and underinsured patients. The purpose of this study was to examine the effects of race, income, and insurance status on receipt of and outcomes following ambulatory cholecystectomy. MATERIALS AND METHODS: Retrospective observational cohort study of patients 18-89 undergoing cholecystectomy for benign indications in Florida, Iowa, and New York, 2011-2014 using administrative databases. The primary outcome of interest was odds of having ambulatory cholecystectomy; secondary outcomes included intraoperative and postoperative complications, and 30-day unplanned admissions following ambulatory cholecystectomy. RESULTS: Among 321,335 cholecystectomies, 190,734 (59.4%) were ambulatory and 130,601 (40.6%) were inpatient. Adjusting for age, sex, insurance, income, residential location, and comorbidities, the odds of undergoing ambulatory versus inpatient cholecystectomy were significantly lower in black (aOR = 0.71, 95% CI [0.69, 0.73], P< 0.001) and Hispanic (aOR = 0.71, 95% CI [0.69, 0.72], P< 0.001) patients compared to white patients, and significantly lower in Medicare (aOR = 0.77, 95% CI [0.75, 0.80] P < 0.001), Medicaid (aOR = 0.56, 95% CI [0.54, 0.57], P< 0.001) and uninsured/self-pay (aOR = 0.28, 95% CI [0.27, 0.28], P< 0.001) patients relative to privately insured patients. Patients with Medicaid and those classified as self-pay/uninsured had higher odds of postoperative complications and unplanned admission as did patients with Medicare compared to privately insured individuals. CONCLUSIONS: Racial and ethnic minorities and the underinsured have a higher likelihood of receiving inpatient as compared to ambulatory cholecystectomy. The higher incidence of postoperative complications in these patients may be associated with unequal access to ambulatory surgery.

BACKGROUND: Efficient Emergency Department (ED) throughput depends on several factors, including collaboration and consultation with surgical services. The acute care surgery service (ACS) collaborated with ED to implement a new process termed "FASTPASS" (FP), which might improve patient-care for those with acute appendicitis and gallbladder disease. The aim of this study was to evaluate the 1-year outcome of FP. METHODS: FASTPASS is a joint collaboration between ACS and ED. ED physicians were provided with a simple check-list for diagnosing young males (<50-year old) with acute appendicitis (AA) and young males or females (<50-year old) with gallbladder disease (GBD). Once ED deemed patients fit our FP check-list, patients were directly admitted (FASTPASSed) to the observation unit. The ACS then came to evaluate the patients for possible surgical intervention. We performed outcome analysis before and after the institution of the FP. Outcomes of interest were ED length of stay (LOS), time from ED to the operating room (OR) (door-to-knife), hospital LOS (HLOS), and cost. RESULTS: During our 1-year study period, for those patients who underwent GBD/AA surgery, 56 (26%) GBD and 27 (26%) AA patients met FP criteria. Compared to the non-FP patients during FP period, FP halved ED LOS for GBD (7.4 ± 3.0 versus 3.5 ± 1.7 h, P < 0.001) and AA (6.7 ± 3.3 versus. 1.8 ± 1.6 h, P < 0.001). Similar outcome benefits were observed for door-to-knife time, HLOS, and costs. CONCLUSIONS: In this study, the FP process improved ED throughput in a single, highly-trained ER leading to an overall improved patient care process. A future study involving multiple EDs and different disease processes may help decrease ED overcrowding and improve healthcare system efficiency.

OBJECTIVE. The purpose of this study was to report national utilization trends and outcomes after percutaneous cholecystostomy, cholecystectomy, or no intervention among patients admitted to hospitals with acute cholecystitis. MATERIALS AND METHODS. The Nationwide Inpatient Sample was queried from 2005 to 2014. Admissions were identified and stratified into treatment groups of percutaneous cholecystostomy, cholecystectomy, and no intervention on the basis of International Classification of Diseases, 9th revision, codes. Outcomes, including length of stay, inpatient mortality, and complications including hemorrhage and bile peritonitis, were identified. Multivariate analysis was performed to identify mortality risk by treatment type after adjustment for baseline comorbidities and risk of mortality. RESULTS. Among 2,550,013 patients (58.6% women, 41.4% men; mean age, 55.9 years) admitted for acute cholecystitis over the study duration, 73,841 (2.9%) patients underwent percutaneous cholecystostomy, 2,005,728 (78.7%) underwent cholecystectomy, and 459,585 (18.0%) did not undergo either procedure. Use of percutaneous cholecystostomy increased from 2985 procedures in 2005 to 12,650 in 2014. The percutaneous cholecystostomy cohort had a higher mean age (70.6 years) than the other two groups (cholecystectomy, 53.8 years; no intervention, 62.5 years), a higher mean comorbidity index (cholecystostomy, 3.74; cholecystectomy, 1.77; no intervention, 2.65), and a higher mean risk of mortality index (cholecystostomy, 2.88; cholecystectomy, 1.45; no intervention, 2.07) (p < .05). Unadjusted inpatient all-cause mortality was 10.1% in the percutaneous cholecystostomy, 0.8% in the cholecystectomy, and 5.2% in the no intervention cohorts. After adjustment for baseline mortality risk, percutaneous cholecystostomy (odds ratio, 0.78; 95% CI, 0.76-0.81) and cholecystectomy (odds ratio, 0.42; 95% CI, 0.41-0.43) were associated with reduced mortality compared with no intervention. CONCLUSION. Use of percutaneous cholecystostomy is increasing among patients admitted with acute cholecystitis. After adjustment for baseline comorbidities, percutaneous cholecystostomy is associated with improved odds of survival compared with no intervention.

PURPOSE: Previous studies have indicated an increased risk of gallbladder disease with hormonal contraceptives although with discordant results. The potential increased risk of gallbladder disease with hormonal contraceptives is concerning given that women are at increased risk of this disease. Thus, the aim of this study was to examine risk of surgery-confirmed gallbladder disease (cholecystectomy) with oral contraceptives, intrauterine devices, and injectable hormonal contraceptives. METHODS: We conducted a retrospective cohort study. Females aged 15-45 who initiated hormonal contraceptive use were identified in the United States IQVIA Ambulatory electronic medical record database between 2008 and 2018. Cox proportional hazards models were used to estimate adjusted hazards ratios and 95% confidence intervals for cholecystectomy with eight formulations of contraceptives compared with levonorgestrel and ethinyl estradiol combined oral contraceptive. Sensitivity analysis was conducted by lagging exposure by 90 days and by excluding patients with history of gallbladder disease. Secondary analyses were conducted by cumulative duration of use. RESULTS: We identified 1,425,821 females who initiated the use of hormonal contraceptives and generated 4417 cholecystectomy events. Overall, the use of medroxyprogesterone acetate (HR: 1.22, 95% CI: 1.07-1.40) and at least 1 year of levonorgestrel intrauterine device use (HR: 1.74: 95% CI: 1.19-2.54) were associated with increased risk of cholecystectomy when compared with levonorgestrel and ethinyl estradiol combined oral contraceptive. However, we did not observe an increased risk with other hormonal contraceptives. Consistent results were observed across sensitivity analyses. CONCLUSION: In this large population-based study, there was an increased risk of cholecystectomy with medroxyprogesterone acetate and intrauterine device but not other hormonal contraceptives. Additional large observational studies are required to corroborate these findings.

BACKGROUND: Deferral of surgeries due to COVID-19 has negatively affected access to elective surgery and may have deleterious consequences for patient's health. Delays in access to elective surgery are not uniform in their impact on patients with different attributes. The objective of this study is to measure the change in patient's cost utility due to delayed elective cholecystectomy. METHODS: This study is based on retrospective analysis of a longitudinal sample of participants who have had elective cholecystectomy and completed the EQ-5D(3L) measuring health status preoperatively and postoperatively. Emergent cases were excluded. Patients younger than 19 years of age, unable to communicate in English or residing in a long-term care facility were ineligible. Quality-adjusted life years attributable to cholecystectomy were calculated by comparing health state utility values between the pre- and postoperative time points. The loss in quality-adjusted life years due to delayed access was calculated under four assumed scenarios regarding the length of the delay. The mean cost per quality-adjusted life years are shown for the overall sample and by sex and age categories. RESULTS: Among the 646 eligible patients, 30.1% of participants (N = 195) completed their preoperative and postoperative EQ-5D(3L). A delay of 12 months resulted in a mean loss of 6.4%, or 0.117, of the quality-adjusted life years expected without the delay. Among patients older than 70 years of age, a 12-month delay in their surgery corresponded with a 25.1% increase in the cost per quality-adjusted life years, from $10 758 to $13 463. CONCLUSIONS: There is a need to focus on minimizing loss of quality of life for patients affected by delayed surgeries. Faced with equal delayed access to elective surgery, triage may need to prioritize older patients to maximize their health over their remaining life years.

Intracholecystic papillary neoplasm (ICPN) is a recently proposed gallbladder neoplasm. Its prevalence and pathologies remain to be clarified. A total of 38 ICPN cases (28 ICPNs identified among 1904 cholecystectomies (1.5%) and in 100 surgically resected primary gallbladder neoplasms (28%) in Fukui Prefecture Saiseikai Hospital, Japan, and other 10 ICPNs) were examined pathologically and immunohistochemically. They were composed of 21 males and 17 females with a mean age of 75 years old, and presented intraluminal growth of papillary lesions with fine fibrovascular stalks. ICPNs were relatively frequent in the fundus (n = 11) and body (n = 9). Grossly, the conglomerated sessile type (n = 30) was more frequent than the isolated polypoid type (n = 8). All cases were classified as high-grade dysplasia, and they were further divided into 22 cases presenting irregular structures and 16 cases presenting regular structures. The former showed frequent complicated lesions and stromal invasion (54.5%) compared to the latter (12.5%). Twenty-four cases showed predominantly either of four subtypes (11 gastric, 7 intestinal, 4 biliary and 2 oncocytic subtype), while the remaining14 cases showed mixture of more than two subtypes. In conclusion, ICPN presented unique preinvasive neoplasm with characteristic histopathologies. Irregular histologies and complicated lesions of ICPN were related to stromal invasion.

OBJECTIVE: To determine whether catheterization of the common bile duct (CBD) is associated with outcome in dogs undergoing cholecystectomy for gallbladder mucocele and to determine whether this association is modified by the catheterization method. STUDY DESIGN: Multi-institutional retrospective cohort study. ANIMALS: Dogs (n = 252) that underwent cholecystectomy for gallbladder mucocele. METHODS: Dogs were identified via electronic medical record review at four veterinary teaching hospitals. Baseline dog characteristics, surgical findings, and methods including normograde vs retrograde CBD catheterization, intraoperative outcomes, and postoperative outcomes and complications were recorded. Variables were compared between dogs with and without catheterization. RESULTS: Catheterized dogs had higher American Society of Anesthesiologists scores (P = .04), higher total bilirubin (P = .01), and were more likely to have dilated CBD at the time of surgery (P < .01). Incidence of major and minor intraoperative complications was similar between the two groups. Surgical time was longer for the catheterized group (P = .01). The overall incidence of postoperative complications was similar between the groups; however, postoperative pancreatitis was associated with performing CBD catheterization (P = .01). This association was retained as an independent association in a multivariable model that addressed baseline group differences (P = .04). Likelihood of developing postoperative pancreatitis was not different between normograde and retrograde catheterization (P = .57). CONCLUSION: Catheterization of the CBD was associated with development of postoperative pancreatitis. This was not influenced by the method of catheterization. CLINICAL SIGNIFICANCE: The requirement for catheterization of the CBD during open cholecystectomy in dogs should be carefully considered, particularly in dogs without evidence of biliary obstruction because the procedure may induce postoperative pancreatitis.

BACKGROUND: International guidelines advise laparoscopic cholecystectomy to treat symptomatic, uncomplicated gallstones. Usual care regarding cholecystectomy is associated with practice variation and persistent post-cholecystectomy pain in 10-41% of patients. We aimed to compare the non-inferiority of a restrictive strategy with stepwise selection with usual care to assess (in)efficient use of cholecystectomy. METHODS: We did a multicentre, randomised, parallel-arm, non-inferiority study in 24 academic and non-academic hospitals in the Netherlands. We enrolled patients aged 18-95 years with abdominal pain and ultrasound-proven gallstones or sludge. Patients were randomly assigned (1:1) to either usual care in which selection for cholecystectomy was left to the discretion of the surgeon, or a restrictive strategy with stepwise selection for cholecystectomy. For the restrictive strategy, cholecystectomy was advised for patients who fulfilled all five pre-specified criteria of the triage instrument: 1) severe pain attacks, 2) pain lasting 15-30 min or longer, 3) pain located in epigastrium or right upper quadrant, 4) pain radiating to the back, and 5) a positive pain response to simple analgesics. Randomisation was done with an online program, implemented into a web-based application using blocks of variable sizes, and stratified for centre (academic versus non-academic and a high vs low number of patients), sex, and body-mass index. Physicians and patients were masked for study-arm allocation until after completion of the triage instrument. The primary, non-inferiority, patient-reported endpoint was the proportion of patients who were pain-free at 12 months' follow-up, analysed by intention to treat and per protocol. A 5% non-inferiority margin was chosen, based on the estimated clinically relevant difference. Safety analyses were also done in the intention-to treat population. This trial is registered at the Netherlands National Trial Register, number NTR4022. FINDINGS: Between Feb 5, 2014, and April 25, 2017, we included 1067 patients for analysis: 537 assigned to usual care and 530 to the restrictive strategy. At 12 months' follow-up 298 patients (56%; 95% CI, 52·0-60·4) were pain-free in the restrictive strategy group, compared with 321 patients (60%, 55·6-63·8) in usual care. Non-inferiority was not shown (difference 3·6%; one-sided 95% lower CI -8·6%; pnon-inferiority=0·316). According to a secondary endpoint analysis, the restrictive strategy resulted in significantly fewer cholecystectomies than usual care (358 [68%] of 529 vs 404 [75%] of 536; p=0·01). There were no between-group differences in trial-related gallstone complications (40 patients [8%] of 529 in usual care vs 38 [7%] of 536 in restrictive strategy; p=0·16) and surgical complications (74 [21%] of 358 vs 88 [22%] of 404, p=0·77), or in non-trial-related serious adverse events (27 [5%] of 529 vs 29 [5%] of 526). INTERPRETATION: Suboptimal pain reduction in patients with gallstones and abdominal pain was noted with both usual care and following a restrictive strategy for selection for cholecystectomy. However, the restrictive strategy was associated with fewer cholecystectomies. The findings should encourage physicians involved in the care of patients with gallstones to rethink cholecystectomy, and to be more careful in advising a surgical approach in patients with gallstones and abdominal symptoms.

BACKGROUND: Though cannabis is gaining broader acceptance among society and a noted increase in legalization, little is known regarding its impact on post-operative outcomes. We conducted this study to quantify the relationship between cannabis abuse or dependence (CbAD) on post-operative outcomes after cholecystectomy and appendectomy. METHODS: Using the 2013-2015 Nationwide Readmissions Database, we identified discharges associated with cholecystectomy or appendectomy from January 2013-August 2015. Patients were grouped by CbAD history. The primary outcomes were length of stay, serious adverse events, home discharge, and 30-day readmission. Propensity-score matching was used to account for differences between groups and all statistics accounted for the matched sample. RESULTS: The final sample included 3288 patients with a CbAD history matched 1:1 to patients without a CbAD history (total sample = 6576). After matching, acceptable balance was achieved in clinical characteristics between groups. In the cholecystectomy cohort (n = 1707 pairs), CbAD patients had longer hospitalizations (3.5 versus 3.2 d, P 0.003) and similar rates of serious adverse events (6.1 versus 4.8, P 0.092), home discharge (96.1 vs 96.2, P 0.855), and readmission (8.3 versus 6.9, P 0.137). In the appendectomy cohort (n = 1581 pairs), CbAD patients had longer hospital stays (2.7 versus 2.5 d, P 0.024); more frequent serious adverse events (5.0 versus 3.5, P 0.041); and similar home discharge (96.8 vs 97.3, P 0.404) and readmission (5.4 versus 5.1, P 0.639) rates. CONCLUSIONS: Patients with a history of CbAD in the cholecystectomy and appendectomy cohorts had slightly longer hospital stays, and patients with a history of CbAD in the appendectomy group displayed a slight increase in adverse events, but otherwise similar clinical outcomes without clinically significant increases in complications compared to patients without this history.

BACKGROUND: Seasonal variation in the occurrence of medical illnesses reflects the effect of the environment, provides insight into pathogenesis, and can assist health care administrators in allocating resources accordingly. Seasonal variation has been reported in various infectious and surgical diseases, but has been rarely studied in acute cholecystitis. Our objective was to study seasonal variation in acute cholecystitis at our institution. METHODS: We performed a retrospective analysis of patients who underwent cholecystectomy for acute cholecystitis from January 1988 to December 2018. Chi-square goodness-of-fit test was used to analyze seasonality of acute cholecystitis adjusting for variation in number of days between seasons. The number of days for seasons were taken as 92, 92, 91, and 90.25 for spring, summer, fall, and winter, respectively. RESULTS: Overall, 3924 patients underwent cholecystectomy for acute cholecystitis during the study period. The frequency of cholecystectomies performed varied between months (minimum February n = 259, maximum July n = 372, P < 0.001) and seasons (minimum winter n = 789, maximum summer n = 1101 P < 0.001). Age and gender distribution across months and seasons was similar (P > 0.05). CONCLUSIONS: Our findings confirm seasonal variation in occurrence of acute cholecystitis with summer season witnessing the most and the winter season encountering the least patients with acute cholecystitis. Validation of our findings through prospectively collected data at national level is the way forward.

BACKGROUND: Several composite measures of neighborhood social vulnerability exist and are used in the health disparity literature. This study assesses the performance of the Social Vulnerability Index (SVI) compared with three similar measures used in the surgical literature: Area Deprivation Index (ADI), Community Needs Index (CNI), and Distressed Communities Index (DCI). There are advantages of the SVI over these other scales, and we hypothesize that it performs equivalently. METHODS: We identified all cholecystectomies at a single, urban, academic hospital over a 9-month period. Cases were considered emergency if the patient presented and underwent surgery during that admission. We geocoded patient's addresses and assigned estimated SVI, ADI, CNI, and DCI. Cutoffs for high versus low social vulnerability were generated using Youden's index, and the scales were compared using multivariable modeling. RESULTS: Overall, 366 patients met inclusion criteria, and the majority (n = 266, 73%) had surgery in the emergency setting. On multivariable modeling, patients with high social vulnerability were more likely to undergo emergency surgery compared with those with low social vulnerability in accordance with all four scales: SVI (OR 3.24, P < 0.001), ADI (OR 3.2, P < 0.001), CNI (OR 1.90, P = 0.04), and DCI (OR 2.01, P = 0.03). The scales all had comparable predictive value. CONCLUSIONS: The SVI performs similarly to other indices of neighborhood vulnerability in demonstrating disparities between emergency and elective surgery and is readily available and updated. Because the SVI has multiple subcategories in addition to the overall measure, it can be used to stratify by modifiable factors such as housing or transportation to inform interventions.

BACKGROUND: Gallbladder cancer is rare but associated with significant morbidity and mortality necessitating the early identification of premalignant and malignant lesions to improve overall prognosis. Despite limited evidence regarding the effectiveness of transabdominal ultrasound (US) in the detection of gallbladder polyps, it plays a key role in current European guidelines. The aim of this study was to investigate gallbladder polyp prevalence in a western European population and assess the diagnostic accuracy of transabdominal US. METHODS: Data from patients who underwent cholecystectomy for US detected gallbladder polypoid lesions at four hospitals in Ireland and the United Kingdom between 2010 and 2018 were retrospectively collected. Patient demographics, ultrasonographic, and histopathologic findings were analyzed. RESULTS: A total of 134 patients underwent cholecystectomy for US-detected gallbladder polyps. After histopathologic examination, pseudopolyps were found in 75 (56%) specimens with dysplastic or malignant polyps seen in only six (4.5%) specimens. Mean size for neoplastic polyps was 33 mm. The positive predictive value for US in detecting neoplastic polyps in this study was 4.5%, which is significantly lower than the 10%-15% reported previously. CONCLUSIONS: Although the prevalence of neoplastic polyps in this study is higher than in the previous literature, the distribution of pseudopolyps and true polyps is as expected. With all malignant polyps being >10 mm in diameter, these findings support the current size thresholds stated in European guidelines. The poor diagnostic accuracy of US demonstrated may have led to significant number of patients undergoing unnecessary surgical intervention, further supporting the argument for improved strategies for the investigation of gallbladder polyps.

INTRODUCTION: The purpose of this study was to evaluate the rate of cholecystectomy before and after adoption of an emergency general surgery (EGS) model at our institution. METHODS: A longitudinal, observational study was conducted prior to and following introduction of an EGS model at our institution. Using the New York SPARCS Administrative Database, all adult patients presenting to the emergency department with gallbladder-related emergencies were identified. The rates of laparoscopic and open cholecystectomies performed 3 years prior and 3 years following the adoption of the EGS model were examined. A multivariable logistic regression model was used to compare the incidence of cholecystectomy at initial ED visit at our institution pre- and post-EGS introduction as well as to those in the rest of the state as an external control group, while adjusting for potentially confounding factors. RESULTS: There were 176,159 total ED visits of patients with gallbladder emergencies (154,743 excluding repeat presenters) in the studied period in NY State. Of these, 63,912 patients (41.3%) had a concurrent cholecystectomy in NY State. The rate of cholecystectomy at these institutions remained relatively steady from 38.8% from 2010 to 2013 and 38.6% from 2013 to 2016. At our institution, there were 2039 gallbladder emergencies, and of those 755 underwent cholecystectomy. At our institution, there was an increase from 28.21% 3 years prior to the adoption of the EGS model to 40.2% in the following 3 years (RR = 1.06, 95% CI 1.0164-1.1078, p = 0.0069). CONCLUSION: The initiation of the EGS model at a tertiary center was associated with a significant increase in the number of concurrent cholecystectomies from 28.21 to 40.2% over a 6-year period. This change was accompanied by an increase in the number of patient comorbidities and a lower insurance status.
