Index admission cholecystectomy for biliary acute pancreatitis or choledocholithiasis reduces 30-day readmission rates in children.

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.

Robotic Technology in Emergency General Surgery Cases in the Era of Minimally Invasive Surgery.

Importance: Although robotic surgery has become an established approach for a wide range of elective operations, data on its utility and outcomes are limited in the setting of emergency general surgery. Objectives: To describe temporal trends in the use of laparoscopic and robotic approaches and compare outcomes between robotic and laparoscopic surgery for 4 common emergent surgical procedures. Design, Setting, and Participants: A retrospective cohort study of an all-payer discharge database of 829 US facilities was conducted from calendar years 2013 to 2021. Data analysis was performed from July 2022 to November 2023. A total of 1 067 263 emergent or urgent cholecystectomies (n = 793 800), colectomies (n = 89 098), inguinal hernia repairs (n = 65 039), and ventral hernia repairs (n = 119 326) in patients aged 18 years or older were included. Exposure: Surgical approach (robotic, laparoscopic, or open) to emergent or urgent cholecystectomy, colectomy, inguinal hernia repair, or ventral hernia repair. Main Outcomes and Measures: The primary outcome was the temporal trend in use of each operative approach (laparoscopic, robotic, or open). Secondary outcomes included conversion to open surgery and length of stay (both total and postoperative). Temporal trends were measured using linear regression. Propensity score matching was used to compare secondary outcomes between robotic and laparoscopic surgery groups. Results: During the study period, the use of robotic surgery increased significantly year-over-year for all procedures: 0.7% for cholecystectomy, 0.9% for colectomy, 1.9% for inguinal hernia repair, and 1.1% for ventral hernia repair. There was a corresponding decrease in the open surgical approach for all cases. Compared with laparoscopy, robotic surgery was associated with a significantly lower risk of conversion to open surgery: cholecystectomy, 1.7% vs 3.0% (odds ratio [OR], 0.55 [95% CI, 0.49-0.62]); colectomy, 11.2% vs 25.5% (OR, 0.37 [95% CI, 0.32-0.42]); inguinal hernia repair, 2.4% vs 10.7% (OR, 0.21 [95% CI, 0.16-0.26]); and ventral hernia repair, 3.5% vs 10.9% (OR, 0.30 [95% CI, 0.25-0.36]). Robotic surgery was associated with shorter postoperative lengths of stay for colectomy (-0.48 [95% CI, -0.60 to -0.35] days), inguinal hernia repair (-0.20 [95% CI, -0.30 to -0.10] days), and ventral hernia repair (-0.16 [95% CI, -0.26 to -0.06] days). Conclusions and Relevance: While robotic surgery is still not broadly used for emergency general surgery, the findings of this study suggest it is becoming more prevalent and may be associated with better outcomes as measured by reduced conversion to open surgery and decreased length of stay.

ROBOtic Care Outcomes Project for acute gallbladder pathology.

BACKGROUND: Robotic cholecystectomy is being increasingly used for patients with acute gallbladder disease who present to the emergency department, but clinical evidence is limited. We aimed to compare the outcomes of emergent laparoscopic and robotic cholecystectomies in a large real-world database. METHODS: Patients who received emergent laparoscopic or robotic cholecystectomies from 2020 to 2022 were identified from the Intuitive Custom Hospital Analytics database, based on deidentified extraction of electronic health record data from US hospitals. Conversion to open or subtotal cholecystectomy and complications were defined using ICD10 and/or CPT codes. Multivariate logistic regression with inverse probability treatment weighting (IPTW) was performed to compare clinical outcomes of laparoscopic versus robotic approach after balancing covariates. Cost analysis was performed with activity-based costing and adjustment for inflation. RESULTS: Of 26,786 laparoscopic and 3,151 robotic emergent cholecystectomy patients being included, 64% were female, 60% were ≥45 years, and 24% were obese. Approximately 5.5% patients presented with pancreatitis, and 4% each presenting with sepsis and biliary obstruction. After IPTW, distributions of all baseline covariates were balanced. Robotic cholecystectomy decreased odds of conversion to open (odds ratio, 0.68; 95% confidence interval, 0.49-0.93; p = 0.035), but increased odds of subtotal cholecystectomy (odds ratio, 1.64; 95% confidence interval, 1.03-2.60; p = 0.037). Surgical site infection, readmission, length of stay, hospital acquired conditions, bile duct injury or leak, and hospital mortality were similar in both groups. There was no significant difference in hospital cost. CONCLUSION: Robotic cholecystectomy has reduced odds of conversion to open and comparable complications, but increased odds of subtotal cholecystectomy compared with laparoscopic cholecystectomy for acute gallbladder diseases. Further work is required to assess the long-term implications of these differences. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Comprehensive assessment of the management of acute cholecystitis in Scotland: population-wide cohort study.

BACKGROUND: Acute cholecystitis is one of the most common diagnoses presenting to emergency general surgery and is managed either operatively or conservatively. However, operative rates vary widely across the world. This real-world population analysis aimed to describe the current clinical management and outcomes of patients with acute cholecystitis across Scotland, UK. METHODS: This was a national cohort study using data obtained from Information Services Division, Scotland. All adult patients with the admission diagnostic code for acute cholecystitis were included. Data were used to identify all patients admitted to Scottish hospitals between 1997 and 2019 and outcomes tracked for inpatients or after discharge through the unique patient identifier. This was linked to death data, including date of death. RESULTS: A total of 47 558 patients were diagnosed with 58 824 episodes of acute cholecystitis (with 27.2 per cent of patients experiencing more than one episode) in 46 Scottish hospitals. Median age was 58 years (interquartile range (i.q.r.) 43-71), 64.4 per cent were female, and most (76.1 per cent) had no comorbidities. A total of 28 741 (60.4 per cent) patients had an operative intervention during the index admission. Patients who had an operation during their index admission had a lower risk of 90-day mortality compared with non-operative management (OR 0.62, 95% c.i. 0.55-0.70). CONCLUSION: In this study, 60 per cent of patients had an index cholecystectomy. Patients who underwent surgery had a better survival rate compared with those managed conservatively, further advocating for an operative approach in this cohort.

Liver transplantation for iatrogenic injuries secondary to cholecystectomy: a systematic review.

INTRODUCTION: Iatrogenic injury to the liver hilum during cholecystectomy is a severe surgical complication, with liver transplantation (LT) as the final drastic solution. The authors report the experience of our center and conduct a review of the literature on the outcomes of LT performed in this setting. METHODS: Data sources included MEDLINE, EMBASE, and CENTRAL from inception to 19 June 2022. Studies reporting on patients treated with LT for liver hilar injuries following cholecystectomy were included. Incidence, clinical outcomes, and survival data were synthesized through a narrative review. RESULTS: Twenty-seven articles were identified, including 213 patients. Eleven (40.7%) articles highlighted deaths within 90-days post-LT. Post-LT mortality was reported in 28 (13.1%) patients. Severe complications (≥Clavien III) occurred in at least 25.8% ( n =55) of patients. Within larger cohorts, 1-year overall survival (OS) was 76.5-84.3%, and 5-year OS was 67.2-83.0%. The authors also highlight our own experience managing 14 patients with liver hilar injury secondary to cholecystectomy, of which two required LT. CONCLUSION: While short-term morbidity and mortality is significant, available long-term data suggests reasonable OS in these patients following LT. Future studies are necessary to better understand the relationship between different types of liver hilar injury, transplant indication, and outcomes of LT in this setting.

Usefulness of endoscopic ultrasound in patients with minilithiasis and/or biliary sludge as a cause of symptoms of probable biliary origin after cholecystectomy / Utilidad de la ecoendoscopia en pacientes con minilitiasis y/o barro biliar como causa de síntomas digestivos de probable origen biliar después de la colecistectomía

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.

Introducción: La ecoendoscopia (USE) presenta mayor sensibilidad que la ecografía abdominal para el diagnóstico de litiasis biliar. Esta mayor sensibilidad, sobre todo en diagnóstico de microlitiasis/barro biliar, facilitaría una colecistectomía en pacientes con clínica digestiva de probable origen biliar, aunque podría inducir su sobre indicación.ObjetivosEvaluar el papel de la USE en el diagnóstico de minilitiasis-barro biliar en pacientes con clínica digestiva de probable origen biliar y ecografía normal mediante la resolución de los síntomas después de colecistectomía. Analizar los factores relacionados con la remisión de la sintomatología tras colecistectomía.Pacientes y método: Estudio retrospectivo, longitudinal, en un centro, sobre base de datos prospectiva de 1.121 pacientes sometidos a USE. Setenta y cuatro pacientes cumplían criterios inclusión-exclusión (realización USE para estudio de minilitiasis/barro por síntomas digestivos de probable origen biliar, sin historia de colelitiasis complicada). Se realizó cuestionario telefónico de síntomas a los pacientes colecistectomizados. Los factores relacionados con buena evolución se analizaron con análisis de regresión logística.Resultados: De los 74 pacientes, 50 fueron colecistectomizados (67,5%), edad media 49 años (ESM 2,26) (41 mujeres). El 70% de pacientes (35/50) presentó remisión de la sintomatología (mediana de seguimiento 353,5 días) (IC 95%, 270-632,2). La única variable asociada con una remisión de la sintomatología fue la presencia de cólico biliar típico con una OR de 7,8 (IC 95%, 1,8-34; p=0,006). No se registró ninguna complicación asociada a la USE. Un paciente (2%) sufrió hemoperitoneo y un 18% (9/50) presentaron diarrea post-colecistectomía.Conclusiones: La USE es de gran utilidad para la indicación de colecistectomía en los pacientes con minilitiasis-barro biliar y clínica típica de cólico biliar.

Surgical practice patterns and outcomes in T2 and T3 gallbladder cancer: a population-based study.

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.

CONCLUSIONS: EUS is a very useful technique for the indication of cholecystectomy in patients with minilithiasis/sludge and typical symptoms of biliary colic.

Call for action: Increased healthcare utilization with growing use of percutaneous cholecystectomy tube over initial cholecystectomy in cirrhotics.

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.

Sex Disparities in the Presentation of Gallbladder Disease.

INTRODUCTION: Although gallbladder disease is more common in women, there is a trend toward more complicated cases in male patients. METHODS: All cholecystectomies captured by the National Surgical Quality Improvement Program database for the year 2016 were reviewed. This encompassed 38 736 records. Records were reviewed for age, sex, procedure performed, operative time, postoperative diagnosis, functional status, American Society of Anesthesiologists (ASA) class, preoperative lab values (total bilirubin, alkaline phosphatase, white blood cell count, and aspartate aminotransferase. Descriptive and inferential statistical analyses were conducted. RESULTS: Male patients are more likely to undergo cholecystectomy for a diagnosis of cholecystitis, gallstone pancreatitis, or cholangitis than women who are more likely to carry a diagnosis of biliary dyskinesia. The average operative time increases for both sexes as the patients become older. The average operative time is higher for men than women in all age groups and the variance becomes greater as the patients become older. Age, sex, postoperative diagnosis, ASA class, and functional status were all independently significant in predicting operative time. There was no difference in need for cholangiogram between the sexes. Female patients were more likely to have their cholecystectomy completed laparoscopically and they were more likely to have their surgery performed as an outpatient. CONCLUSION: These data show that women were more likely to present with uncomplicated gallbladder disease, while men were more likely to present with complicated gallbladder disease. This suggests that male patients present at a more advanced stage of disease.

A nationwide analysis of gallbladder surgery in England between 2000 and 2019.

BACKGROUND: There are no reports on nationwide trends in subtotal cholecystectomy (STC) and cholecystostomy in England. We hypothesized that, as in the United States, a substantial increase in the utilization of these surgical procedures, over time, may be observed. We aimed to generate a reliable report on 4 of the most common gallbladder surgical procedures in England to allow cross-procedure comparisons and highlight significant changes in the management of benign gallbladder disease over time. METHODS: We obtained data from NHS Digital and extracted population estimates from the Office of National Statistics. We examined the trends in the use of STC, cholecystostomy, cholecystolithotomy and total cholecystectomy (TC) between 2000 and 2019. RESULTS: Of the 1,234,319 gallbladder surgeries performed, TC accounted for 96.8% (n = 1,194,786) and the other 3 surgeries for 3.2% (n = 39,533). The total number of gallbladder surgeries performed annually increased by 80.4% from 2000 to 2019. We detected increases in the counts of cholecystostomies by 723.1% (n = 290 in 2000 vs n = 2,387 in 2019) and STCs by 716.6% (n = 217 in 2000 vs n = 1,772 in 2019). Consequently, there was a decrease in the ratio of TC to STC (180:1 in 2000 vs 38:1 in 2019). A similar decrease was observed in the ratio of cholecystectomy to cholecystostomy (135:1 in 2000 vs 29:1 in 2019). CONCLUSION: Increased utilization of STC and cholecystostomy was detected in England. These findings highlight the importance of regular monitoring of nationwide trends in gallbladder surgery and the associated clinical outcomes.

Emergency General Surgery Procedures and Cost of Care for Older Adults in the State of Maryland.

BACKGROUND: Older adults (OAs) ≥ 65 years of age, representing the fastest growing segment in the United States, are anticipated to require a greater percentage of emergency general surgery procedures (EGSPs) with an associated increase in health care costs. The aims of this study were to identify the frequency of EGSP and charges incurred by OA compared to their younger counterparts in the state of Maryland. METHODS: A retrospective review of the Maryland Health Services Cost Review Commission from 2009 to 2018 was undertaken. Patients undergoing urgent or emergent ESGP were divided into 2 groups (18-64 years and ≥65 years). Data collected included demographics, APR-severity of illness (SOI), APR-risk of mortality (ROM), the EGSP (partial colectomy [PC], small bowel resection [SBR], cholecystectomy, operative management of peptic ulcer disease, lysis of adhesions, appendectomy, and laparotomy), length of stay (LOS), and hospital charges. P-values (P < .05) were significant. RESULTS: Of the 181,283 patients included in the study, 55,401 (38.1%) were ≥65 years of age. Older adults presented with greater APR-SOI (major 37.7% vs 21.3%, extreme 5.2% vs 9.3%), greater APR-ROM (major 25.3% vs 8.7%, extreme 22.3% vs 5.3%), underwent PC (24.5% vs 10.9%) and SBR (12.8% vs 7.0%) more frequently, and incurred significantly higher median hospital charges for every EGSP, consistently between 2009 and 2018 due to increased LOS and complications when compared to those ≤65 years of age. CONCLUSION: These findings stress the need for validated frailty indices and quality improvement initiatives focused on the care of OAs in emergency general surgery to maximize outcomes and optimize cost.

Gallstone Disease and Risk of Conventional Adenomas and Serrated Polyps: A Prospective Study.

BACKGROUND: Gallstone disease has been associated with colorectal cancer and some form of polyps, although the findings are inconclusive. It remains unknown whether gallstone disease influences the initiation of colorectal cancer. METHODS: We prospectively assessed the association of gallstone disease with risk of colorectal cancer precursors, including conventional adenomas and serrated polyps, in the Nurses' Health Study (1992-2012), the Nurses' Health Study II (1991-2011), and the Health Professionals Follow-up Study (1992-2012). Gallstone diseases were assessed using biennial follow-up questionnaires. Self-reported polyp diagnosis was confirmed by review of medical records. Logistic regression models were used to calculate the ORs with adjustment for smoking and other potential confounders. RESULTS: Among participants who had undergone a total of 323,832 endoscopies, 16.5% had gallstone disease and 11.3% received cholecystectomy. We documented 1,724, 1,212, and 1,943 cases of conventional adenomas and 1,470, 1,090, and 1,643 serrated polyps in patients with gallstones, cholecystectomy, and either of them, respectively. The OR for adenomas was 1.00 [95% confidence interval (CI): 0.95-1.06] for gallstones, 0.99 (95% CI, 0.93-1.06) for cholecystectomy, and 1.00 (95% CI, 0.95-1.05) for either exposure. The corresponding ORs for serrated polyps were 0.98 (95% CI, 0.92-1.04), 0.99 (95% CI, 0.93-1.06), and 0.97 (95% CI, 0.92-1.03), respectively. CONCLUSIONS: Gallstone disease is not associated with colorectal polyps. IMPACT: Patients with gallstones appear to have similar risk of colorectal polyps compared with those without and may therefore follow average-risk colorectal cancer screening guidelines.

Impact of Early Cholecystectomy on the Cost of Treating Mild Gallstone Pancreatitis: Gallstone PANC Trial.

BACKGROUND: The Gallstone Pancreatitis: Admission vs Normal Cholecystectomy (Gallstone PANC) Trial demonstrated that cholecystectomy within 24 hours of admission (early) compared with after clinical resolution (control) for mild gallstone pancreatitis, significantly reduced 30-day length-of-stay (LOS) without increasing major postoperative complications. We assessed whether early cholecystectomy decreased 90-day healthcare use and costs. STUDY DESIGN: A secondary economic evaluation of the Gallstone PANC Trial was performed from the healthcare system perspective. Costs for index admissions and all gallstone pancreatitis-related care 90 days post-discharge were obtained from the hospital accounting system and inflated to 2020 USD. Negative binomial regression models and generalized linear models with log-link and gamma distribution, adjusting for randomization strata, were used. Bayesian analysis with neutral prior was used to estimate the probability of cost reduction with early cholecystectomy. RESULTS: Of 98 randomized patients, 97 were included in the analyses. Baseline characteristics were similar in early (n = 49) and control (n = 48) groups. Early cholecystectomy resulted in a mean absolute difference in LOS of -0.96 days (95% CI, -1.91 to 0.00, p = 0.05). Ninety-day mean total costs were $14,974 (early) vs $16,190 (control) (cost ratio [CR], 0.92; 95% CI, 0.73-1.15, p = 0.47), with a mean absolute difference of $1,216 less (95% CI, -$4,782 to $2,349, p = 0.50) per patient in the early group. On Bayesian analysis, there was an 81% posterior probability that early cholecystectomy reduced 90-day total costs. CONCLUSION: In this single-center trial, early cholecystectomy for mild gallstone pancreatitis reduced 90-day LOS and had an 81% probability of reducing 90-day healthcare system costs.

Impact of frailty on clinical outcomes and resource use following emergency general surgery in the United States.

BACKGROUND: Frailty has been recognized as an independent risk factor for inferior outcomes, but its effect on emergency general surgery (EGS) is understudied. OBJECTIVE: The purpose of the present study was to define the impact of frailty on risk-adjusted mortality, non-home discharge, and readmission following EGS operations. METHODS: Adults undergoing appendectomy, cholecystectomy, small bowel resection, large bowel resection, repair of perforated ulcer, or laparotomy within two days of an urgent admission were identified in the 2016-2017 Nationwide Readmissions Database. Frailty was defined using diagnosis codes corresponding to the Johns Hopkins Adjusted Clinical Groups frailty indicator. Multivariable regression was used to study in-hospital mortality and non-home discharge by operation, and Kaplan Meier analysis to study freedom from unplanned readmission at up to 90-days follow-up. RESULTS: Among 655,817 patients, 11.9% were considered frail. Frail patients most commonly underwent large bowel resection (37.3%) and cholecystectomy (29.2%). After adjustment, frail patients had higher mortality rates for all operations compared to nonfrail, including those most commonly performed (11.9% [95% CI 11.4-12.5%] vs 6.0% [95% CI 5.8-6.3%] for large bowel resection; 2.3% [95% CI 2.0-2.6%] vs 0.2% [95% CI 0.2-0.2%] for cholecystectomy). Adjusted non-home discharge rates were higher for frail compared to nonfrail patients following all operations, including large bowel resection (68.1% [95% CI 67.1-69.0%] vs 25.9% [95% CI 25.2-26.5%]) and cholecystectomy (33.7% [95% CI 32.7-34.7%] vs 2.9% [95% CI 2.8-3.0%]). Adjusted hospitalization costs were nearly twice as high for frail patients. On Kaplan-Meier analysis, frail patients had greater unplanned readmissions (log rank P<0.001), with 1 in 4 rehospitalized within 90 days. CONCLUSIONS: Frail patients have inferior clinical outcomes and greater resource use following EGS, with the greatest absolute differences following complex operations. Simple frailty assessments may inform expectations, identify patients at risk of poor outcomes, and guide the need for more intensive postoperative care.

Disparities in Utilization of Ambulatory Cholecystectomy: Results From Three States.

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.

Association between the use of hormonal contraceptives and risk of cholecystectomy in women of reproductive age.

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.
