Is hyperkinetic gallbladder an indication for cholecystectomy?

Evaluation and Management of Biliary Dyskinesia in Children and Adolescents: A Systematic Review From the APSA Outcomes and Evidence-Based Committee

INTRODUCTION

The diagnosis and management of biliary dyskinesia in children and adolescents remains variable and controversial. The American Pediatric Surgical Association Outcomes and Evidence-Based Practice Committee (APSA OEBP) performed a systematic review of the literature to develop evidence-based recommendations.

METHODS

Through an iterative process, the membership of the APSA OEBP developed five a priori questions focused on diagnostic criteria, indications for cholecystectomy, short and long-term outcomes, predictors of success/benefit, and outcomes of medical management. A systematic review was conducted, and articles were selected for review following Preferred Reporting Items for Systematic Review and Meta-analyses (PRISMA) guidelines. Risk of bias was assessed using Methodologic Index for Non-Randomized Studies (MINORS) criteria. The Oxford Levels of Evidence and Grades of Recommendation were utilized.

RESULTS

The diagnostic criteria for biliary dyskinesia in children and adolescents are not clearly defined. Cholecystectomy may provide long-term partial or complete relief in some patients; however, there are no reliable predictors of symptom relief. Some patients may experience resolution of symptoms with non-operative management.

CONCLUSIONS

Pediatric biliary dyskinesia remains an ill-defined clinical entity. Pediatric-specific guidelines are necessary to better characterize the condition, guide work-up, and provide management recommendations. Prospective studies are necessary to more reliably identify patients who may benefit from cholecystectomy.

Biliary Dyskinesia-Controversies, Diagnosis, and Management: A Review

Importance

Biliary dyskinesia is a disorder characterized by biliary pain, a sonographically normal gallbladder, and a reduced gallbladder ejection fraction on cholecystokinin-cholescintigraphy (CCK-HIDA) scan. Laparoscopic cholecystectomy remains a common treatment for biliary dyskinesia despite a lack of high-quality evidence supporting the practice. The following review summarizes the current biliary dyskinesia outcomes data, the diagnostic strategies and their limitations, biliary dyskinesia in the pediatric population, the emerging phenomenon of the hyperkinetic gallbladder, and suggestions for addressing identified knowledge gaps.

Observations

The majority of studies on the topic are retrospective, with wide variations in inclusion criteria and definition of biliary pain. Most report a very short follow-up interval, often a single office visit, with variable and nonstandardized definitions of a satisfactory outcome. Despite a published Society of Nuclear Medicine guideline for its performance, CCK-HIDA scan protocols vary among institutions, which has led to considerable variability in the consistency and reproducibility of CCK-HIDA results. The few prospective studies available, although small and heterogeneous, support a role for cholecystectomy in the treatment of adult biliary dyskinesia. Despite these knowledge gaps, biliary dyskinesia is now the number 1 indication for cholecystectomy in children. Cholecystectomy for the hyperkinetic gallbladder appears to be an emerging phenomenon, despite, as in biliary dyskinesia, a lack of quality data supporting this practice. Randomized trials addressing these gaps are needed but have been difficult to conduct owing to strong clinician and patient bias toward surgery and the lack of a criterion-standard nonsurgical treatment for the control arm.

Conclusions and Relevance

The use of cholecystectomy for adult biliary dyskinesia is reasonable based on the available data. Insufficient data exist regarding laparoscopic cholecystectomy for pediatric dyskinesia and the hyperkinetic gallbladder population. Large-scale prospective studies, either randomized trials or large prospectively followed cohort studies, are needed to address the knowledge gaps surrounding this controversial diagnosis.

Hyperkinetic Biliary Dyskinesia: An Underrecognized Problem With Good Surgical Outcomes After Cholecystectomy

Introduction While surgical indications for symptomatic cholelithiasis and biliary hypokinesia are clear, hyperkinetic biliary dyskinesia (HBD) is an underrecognized condition with poorly defined symptomology and management guidelines. HBD is typically defined as a gallbladder ejection fraction (EF) ≥ 80% on a hepatobiliary iminodiacetic acid (HIDA) scan. We aimed to identify the prevalence and radiographic reporting of HBD, physician referral patterns, and clinical outcomes following cholecystectomy. Methods  A retrospective cohort study of patients with HIDA scans completed over 21 years at our tertiary care hospital was performed. Demographics, symptomatology, referral patterns, and operative data were collected. HBD was defined as HIDA EF ≥80%. Patients with HBD who underwent cholecystectomy were analyzed. ANOVA and chi-square tests were used to compare variables among patients with or without symptom improvement using Statistical Product and Service Solutions (SPSS; IBM SPSS Statistics for Windows, Armonk, NY). Results Of 1,997 patients (73% female, mean age 51.7 years) who had HIDA scans with reported EF, 730 (36.6%) had an EF≥80%. Only 13.7% of HIDA scans with EF≥80% were reported as hyperkinetic, and the rest are "normal". Cholecystectomy was performed in 57 (7.8%) patients with EF≥80%, most being elective (89.5%) and all minimally invasive. Primary care physicians (PCPs) referred most elective cases to surgery (61.4%). The median time from HIDA to cholecystectomy was 146 days. Chronic cholecystitis was common in pathology (82.5%), while 38.6% had cholelithiasis. Overall, 53 patients (93.0%) reported symptom improvement at a median follow-up of 17.0 days. Patients without improvement had a higher prevalence of chronic gastrointestinal conditions (p<0.05), but not significantly more cholelithiasis, cholecystitis, time to surgery, or elective surgery status. Conclusions HBD is common but often underdiagnosed and thus likely underrecognized by treating physicians. Most HBD patients benefit from cholecystectomy, regardless of cholelithiasis. Patients with persistent symptoms after cholecystectomy may have confounding gastrointestinal diagnoses. Increased awareness among radiologists, referring PCPs, gastroenterologists, and surgeons about HBD and postoperative outcomes is needed to ensure that HBD is adequately treated.

Defining Biliary Hyperkinesia and the Role of Cholecystectomy

BACKGROUND

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.

STUDY DESIGN

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.

RESULTS

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.

CONCLUSIONS

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.

Gallbladder Dyskinesia

Gallbladder dyskinesia is a functional disorder of the gastrointestinal tract, which can result in debilitating episodes of abdominal pain and associated symptoms. Key diagnostic criteria include a diminished gallbladder ejection fraction on scintigraphy and absence of other causes for the symptoms. Pathologic findings and follow-up suggest a distinct mechanistic basis for this condition. Unfortunately, the complexities of diagnosis and treatment combined with patient and provider preferences will likely continue to preclude randomized controlled studies to provide a clearer evidence-based management for this disorder. Patients meeting the clinical and diagnostic criteria for gallbladder dyskinesia should be referred for cholecystectomy, and most of these patients will have relief of their symptoms. A comprehensive preoperative discussion on expected outcomes needs to take place.

The Role of Cholecystectomy in Hyperkinetic Gallbladder: A Retrospective Cohort Study in a Rural Hospital

Background Biliary dyskinesia is a functional gallbladder disorder in which there is an absence of a structural or mechanical cause for biliary pain. A cholecystokinin-hepatobiliary iminodiacetic acid (CCK-HIDA) scan is typically performed during workup, and cholecystectomy is the accepted treatment for low ejection fraction (EF) (less than 33%, as defined by the literature). However, few studies have examined the role of cholecystectomy in hyperkinetic gallbladder (EF ≥80%). The aim of our study was to examine symptom resolution following minimally invasive cholecystectomy in patients with hyperkinetic gallbladder. Methodology A retrospective chart review was conducted at Robert Packer Hospital in Sayre, PA. Patients who underwent minimally invasive cholecystectomy for biliary colic with EF ≥80% and who were without cholelithiasis on preoperative imaging or on final pathology were included in this study. The main outcome was symptom resolution at the postoperative visit. Data collected included age, gender, EF, body mass index, symptoms with CCK infusion, and pathology. Results A total of 48 patients were included. The mean age of patients was 41.2 years (standard deviation = 14.4), and the median age of patients was 42.2 years, with a range of 17-71 years. The majority of patients were female (83.3%). Overall, 58.3% of patients had replication of symptoms with CCK infusion. The mean gallbladder EF was 87.3%, with a median of 87.0 and a range of 80-98. In total, 33 (68.8%) patients had chronic cholecystitis on final pathology reports. There was a 95.9% symptom resolution rate among our patients two weeks postoperatively. Conclusions The overwhelming majority of patients experienced symptom resolution prior to their two-week postoperative visit following minimally invasive cholecystectomy for hyperkinetic gallbladder. These results strongly suggest a role of surgical management in patients with high EF.

Mixed Metal Allergy Ancillary to Surgical Staples

Metal allergies to surgical clips are atypical and often neglected as a differential. It becomes even more unexpected when there is a lack of relevant medical history of the patient reacting poorly to known metals. This study entails the unique finding of newly discovered hypersensitivity to nickel and zirconium, metals commonly found in surgical clips, in a 28-year-old female who underwent laparoscopic cholecystectomy with a cholangiogram.

Pediatric Normokinetic Biliary Dyskinesia: Pain with Cholecystokinin on Hepatobiliary Iminodiacetic Acid Scan Predictive of Symptom Resolution After Cholecystectomy

Introduction: Biliary dyskinesia is typically defined as a gallbladder ejection fraction (EF) <35% on hepatobiliary iminodiacetic acid scan with cholecystokinin stimulation (CCK-HIDA) testing. Cholecystectomy often leads to resolution of associated biliary colic symptoms. Alternatively, there is a subset of symptomatic patients with normal gallbladder EF on CCK-HIDA. It has been proposed that pain with CCK injection is more predictive of symptom resolution after cholecystectomy than low gallbladder EF. We reviewed our experience with pediatric patients with positive CCK provocation testing and a normal gallbladder EF in the absence of gallstones. Materials and Methods: We retrospectively reviewed the records of all pediatric patients with normal hepatobiliary iminodiacetic acid EFs (35%-80%) and pain with CCK injection at a tertiary care center between 2016 and 2020. Age, gender, body mass index (BMI), CCK-HIDA results, and pathology analysis were noted. Short- and long-term resolution of symptoms was determined by patient self-reporting at a mean of 3 weeks and 46 months, respectively. Results: Seventeen patients met inclusion criteria. Average age was 15.1 years (range, 12-17 years) with median BMI 24.9 (± 4.9 kg/m²). Mean CCK-HIDA EF was 56.3% (± 11.4%). In total, 62.5% of patients had evidence of chronic cholecystitis and/or cholesterolosis on pathology analysis. Of patients available for short-term and long-term postoperative follow-up, 80% and 83% reported complete or near complete resolution of symptoms, respectively. Conclusions: Normokinetic biliary dyskinesia is poorly understood but appears to be associated with chronic inflammation and cured by surgical intervention. Laparoscopic cholecystectomy results in resolution of symptoms for a majority of patients and should be considered in those with pain with CCK injection despite normal imaging studies. Clinical Trial Registration Number: 1657640-2.

Is abnormal gallbladder ejection fraction hokum? Retrospective chart review of gallbladder ejection fraction and subsequent postoperative symptom relief, surgical pathology, and current literature review

The purpose of this report is to investigate the clinical importance of increased or decreased gallbladder ejection fraction (GBEF) and ultrasound findings for biliary dyskinesia by evaluating postsurgical symptom relief and surgical pathology. Single institution electronic medical record review was prepared for patients who underwent hepatobiliary iminodiacetic acid (HIDA) scan with GBEF and cholecystectomy between January 2013 and March 2020. Relevant data included patient demographics, ultrasound results, surgical pathology, HIDA with GBEF results, and postoperative symptom relief at the time of follow-up. Student's t-test was also utilized for additional statistical analysis. A total of 67 patients underwent cholecystectomy within a 1-month period of time after HIDA with GBEF. Of these patients, 97% had findings consistent with chronic cholecystitis and 3% of the patients demonstrated both acute and chronic cholecystitis surgical pathology. Fifty-seven percent of the patients demonstrated a GBEF <38%, 30% had a GBEF >80%, and 13% had a GBEF 38%-80% with a postoperative symptom resolution around 82%, 77%, and 100%, respectively. GBEF alone may not be determinative regarding gallbladder pathology or postoperative symptom relief in patients that present with typical symptoms. Regarding dyskinetic gallbladders, elevated and decreased GBEF groups were not significantly different in terms of surgical pathology or symptom relief. These patients may benefit from being treated as a single group rather than as separate entities. Elevated and decreased GBEF groups demonstrated mostly normal ultrasound results that raised concern for the utility of ultrasound as a rule out test for gallbladder inflammation.

Biliary hyperkinesia in adolescents-it isn't all hype!

Background

Biliary dyskinesia generally refers to a hypofunctioning gallbladder with an ejection fraction (EF) of <35% on hepatobiliary iminodiacetic acid scan with cholecystokinin stimulation (CCK-HIDA testing). In adults, biliary hyperkinesia has a defined association with biliary colic symptoms and can be relieved with surgical intervention. This clinical entity has not been well described in children or adolescents. In fact, only recently have we seen biliary hyperkinesia on HIDA at our centers. To that end, we reviewed our recent experience with adolescents who have presented and been treated for this unusual clinical entity.

Methods

With IRB approval, we retrospectively reviewed the records of all patients with abnormally high HIDA EFs (>80%) cared for by the pediatric surgery services at two tertiary care centers over the span of a three-year period. Age, sex, BMI, CCK-HIDA results, and preoperative testing and post-operative pathology were noted. Resolution of symptoms was determined by subjective patient self-reporting at postoperative visit.

Results

Eighteen patients met inclusion criteria. Average age 15.7 (range, 10-17 years), median BMI 27.3 (±8.2). Fifteen patients were female and 3 were male. Average CCK-HIDA EF was 91.6% (±5.2), 82.4% of the patients had evidence of chronic cholecystitis and/or cholesterolosis on pathology. Postoperatively, 82.4% of the patients available for follow up (n=17) reported complete or near complete resolution of symptoms.

Conclusions

Biliary hyperkinesia is an emerging clinical entity in children and adolescents and has a similar presentation to biliary hypokinesia. While the pathophysiologic mechanism of pain is not fully elucidated, laparoscopic cholecystectomy appears to provide a surgical cure for these patients and should be considered in the differential for the patient with an unremarkable workup and history suggestive of biliary colic.

Systematic review and meta-analyses of cholecystectomy as a treatment of biliary hyperkinesia

Biliary hyperkinesia is typically diagnosed in patients with biliary-like pain and no evidence of gall stones on imaging modalities but who have had biliary scintigraphy scan (HIDA) that shows ejection fraction ≥ 80%. This study aims to identify whether the removal of the gall bladder can alleviate the symptoms associated with biliary hyperkinesia. Systematic search following PRISMA guidelines was done from inception to January 2020 using PubMed/Medline, OVID, Embase, Cochrane database of systemic reviews, Cochrane central register of controlled trials, The Database of Abstracts of Reviews of Effects (DARE) and Cochrane library databases. Results were expressed as risk ratios (RR) for dichotomous outcomes together with 95% confidence intervals (CI) or mean differences (MD) or standardized MD (SMD) for continuous outcomes. A meta-analysis was done using random-effect model in RevMan 5.4^® software. Thirteen studies met the inclusion criteria and were included in the review. A total of 332 patients diagnosed with biliary hyperkinesia underwent cholecystectomy, of whom 303 (91.3%) reported symptomatic improvement RR 8.67 (95% CI 4.95, 15.16) P = 0.01. Six studies described abnormal histological features in 163/181 (90.05%) with high GB EF. RR 7.88 (95% CI 3.94, 15.75) P = 0.08. Chronic cholecystitis n = 155 (95%), cholesterolosis n = 7 (4.3%), and one showed features of acute cholecystitis. Patients with typical biliary colic symptoms without gallstones and markedly high ejection fraction might benefit from having cholecystectomy to alleviate their symptoms.

Outcomes After Laparoscopic Cholecystectomy in Hyperkinetic Biliary Dyskinesia

BACKGROUND

Biliary dyskinesia (BD) is a poorly understood functional gallbladder disorder. Diagnosis is made with abdominal pain and an intact gallbladder without signs of anatomical obstruction on imaging or pathology. Our aim was to assess whether laparoscopic cholecystectomy (LC) resolves hyperkinetic BD symptoms.

METHODS

Records of patients ≥18 years of age, who underwent LC by four surgeons at a tertiary care center between 2012 and 2020, were retrospectively reviewed. Patients were excluded if they had a documented gallbladder ejection fraction (GBEF) <80% or had biliary stones or sludge on pathology or imaging. Demographic information, HIDA results, preoperative testing, operative details, gallbladder pathology, and symptom status at follow-up were collected from electronic medical records. Improvement in BD symptoms was assessed using McNemar's test. Risk differences with standard errors were employed to estimate percent reduction in symptoms.

RESULTS

Ninety-eight patients met inclusion criteria. Of those who presented for follow-up (n = 91), 92.3% (n = 84) reported partial or complete resolution of symptoms. Preoperative symptoms, including back pain (16.7%, 95% CI: [7.9%, 25.5%]; P < .0001), epigastric pain (31.1% [21.3%, 41.3%]; P < .0001), nausea (56.7% [45.0%, 65.8%]; P < .0001), RUQ pain (57.8% [46.1%, 66.9%]; P < .0001), and vomiting (27.8% [18.4%, 37.7%]; P < .0001) showed significant improvement after LC. Chronic cholecystitis and/or cholesterolosis were present on pathology in 79.8% of gallbladders.

DISCUSSION

Our study currently represents the largest cohort of patients with hyperkinetic BD. Laparoscopic cholecystectomy appears to result in resolution of symptoms for this clinical entity.

Role of Cholecystectomy in Symptomatic Hyperkinetic Gallbladder Patients

Introduction

Biliary dyskinesia is defined by a gallbladder ejection fraction (EF) of less than 35% on HIDA scan, and these patients have shown a good response to cholecystectomy. Management of patients with biliary colic symptoms who have a hyperkinetic gallbladder (EF > 80%) is not clearly defined. Herein, I report three cases of the symptomatic hyperkinetic gallbladder that were successfully managed with cholecystectomy. Case Report. Patient 1was a 56-year-old female presented with pain in the right upper abdomen for one month. Her workup was unremarkable except for the gallbladder EF of 86%. Patient 2 was a 33-year-old female with similar symptoms and workup with gallbladder EF of 97%. Patient 3 was a 20-year-old female with right upper abdominal pain and gallbladder EF of 91%. Patients 1 and 3 had the normal US, normal CT scan, and normal EGD. Patient 2 had normal US and CT but did not undergo EGD. All three patients underwent laparoscopic cholecystectomy and had complete resolution of their symptoms.

Conclusion

The hyperkinetic gallbladder is a rare phenomenon, which can cause debilitating right upper quadrant pain. All three patients had an excellent response to cholecystectomy. Therefore, it is concluded that the patients with biliary colic and gallbladder EF of 80% or higher should be strongly considered for surgery.

Biliary Dyskinesia: Current Perspectives and Future Directions

Biliary dyskinesia (BD) is a disorder characterized by functional biliary pain, the absence of gallstones on ultrasound, and the finding of a reduced gallbladder ejection fraction on a cholecystokinin-cholescintigraphic scan. Cholecystectomy remains a commonly applied treatment for BD, despite a lack of high-quality evidence supporting the practice. The following article provides an overview of the current diagnostic strategies, treatment outcomes with both surgical and nonsurgical treatment, emerging considerations related to special populations, and suggestions for addressing the identified knowledge gaps, moving forward in an effort to develop stronger, more evidence-based practice guidelines for treating this poorly understood and poorly studied condition.

Optimal Management of the Hyperkinetic Gallbladder: A Comparison of Outcomes Between Operative and Nonoperative Approaches

BACKGROUND

A hyperkinetic gallbladder is defined as a hepatobiliary iminodiacetic acid (HIDA) scan ejection fraction (EF) of >80%. This condition is poorly described, and there is no current consensus on optimal management. The intent of this study was to determine if cholecystectomy improves symptoms in patients with a hyperkinetic gallbladder when compared to those managed nonoperatively and if there were variables predictive of symptom improvement with or without cholecystectomy.

MATERIALS AND METHODS

This retrospective study included patients from 3 academic hospitals in the Atlanta metro area between the years 2006 and 2018. All patients with an EF >80% were included. Following voluntary exclusion patients were contacted by phone. Each patient was administered a questionnaire regarding their surgical history, medical management, and current symptom profile via Otago score. Institutional Institutional Review Board approval was obtained.

RESULTS

4785 HIDA scans were performed, and 194 reported an EF >80% (incidence 15.7%). 96% of these scans were reported as normal by the radiologist. 68 patients were able to be contacted by phone and completed the questionnaire. 18 patients underwent cholecystectomy, and 89% reported that their symptoms attributed to gallbladder disease were no longer present. 50 patients did not undergo cholecystectomy, and alternate diagnoses, medication prescriptions, diet modification, emergency department visits, and Otago score were higher in this cohort.

DISCUSSION

Patients who undergo cholecystectomy for a diagnosis of hyperkinetic gallbladder, on average, report improvement in symptoms when compared to patients managed nonoperatively. This study supports the practice of reporting and managing hyperkinetic gallbladders as a pathologic entity.

Biliary Dyskinesia: Fact or fiction?

Nearly 20,000 pediatric patients undergo cholecystectomy annually, and abnormal gallbladder emptying ("biliary dyskinesia") has replaced cholelithiasis as the leading indication for this operation in the USA. Nonetheless, patients with abnormal gallbladder emptying nuclear medicine scans do not uniformly benefit from cholecystectomy. This article reviews the available data on presentation, workup and treatment of patients with abnormally low and high rates of gallbladder emptying.

Association of gallbladder hyperkinesia with acalculous chronic cholecystitis: A case-control study

BACKGROUND

This is the first case-control study investigating an association between gallbladder hyperkinesia and symptomatic acalculous chronic cholecystitis.

METHODS

This retrospective study in a single academic center compared resolution of biliary pain in adults with gallbladder hyperkinesia, defined as a hepatobiliary iminodiacetic acid scan ejection fraction ≥80%, undergoing cholecystectomy (study group) with those treated medically without cholecystectomy (control group). Of 1,477 hepatobiliary iminodiacetic acid scans done between 2013 and 2018, a total of 296 adults without gallstones had an ejection fraction ≥80%, of whom 46 patients met predetermined eligibility criteria. Demographic data, hepatobiliary iminodiacetic acid scan ejection fraction, chronicity of pain, and resolution of pain were compared between groups.

RESULTS

Demographics (mean ± standard deviation) in the control group (n = 25) and in the study group (n = 21) were, respectively, age 40 y ± 16 y and 39 y ± 14 y, body mass index 28.9 ± 5.2 and 29.1 ± 7.1 kg/m², with 15 (60%) and 18 (86%) females in each. Resolution of pain after cholecystectomy occurred in 18 of 21 patients (86%); however, pain persisted in 20 of 25 patients (80%) treated medically after mean follow-up of 36 ± 28 months (range 10-120 months) (P < .01). Pain resolution with cholecystectomy was independent of demographic variables, hepatobiliary iminodiacetic acid scan ejection fraction, and chronicity of pain. The odds of pain resolution was 19.7 times greater with cholecystectomy than without (odds ratio, 19.7; 95% confidence interval, 4.34, 89.43; P < .01), and remained robust even with the odds adjusted for each covariate. Gallbladder histopathology confirmed chronic cholecystitis in all 21 cholecystectomy specimens.

CONCLUSION

Symptomatic gallbladder hyperkinesia could be a new indication for cholecystectomy in adults.

Biliary hyperkinesia: an indication for cholecystectomy?

BACKGROUND

The main indications for laparoscopic cholecystectomy are stone-related diseases in adults. With a normal abdominal ultrasound (US), a hepatobiliary iminodiacetic acid (HIDA) scan with ejection fraction (EF) is recommended to evaluate gallbladder function. Biliary dyskinesia or low gallbladder EF (EF < 35%) is a recognized indication for cholecystectomy. Recent articles report long-term resolution of symptoms in children with high EFs on the HIDA scan. The purpose of this study is to evaluate the response of patients with biliary colic and hyperkinetic gallbladder to cholecystectomy. We suggest that laparoscopic cholecystectomy might be a considerable surgical option in a subset of the adult population whose workup for food-related biliary abdominal pain is negative except for the high-value EF on HIDA scan.

METHODS

Data were consecutively collected from all patients who underwent laparoscopic cholecystectomy between June 2012 and June 2019 at a single institution. Cases were identified using Current Procedural Terminology codes. Patients older than 17 years of age with the negative US (no stone, no sludge, no gallbladder wall thickening) and EF greater than 80% on cholecystokinin (CCK)-HIDA scan were included in this study. All patients were seen at 2 weeks and 10-16 months after surgeries.

RESULTS

Over 7 years from June 2012 until June 2019, of 2116 patients who underwent laparoscopic cholecystectomy, 59 patients (2.78%) met study criteria. Postprandial abdominal pain was the most common symptom (43, 72.90%) followed by nausea/vomiting. Forty-seven patients (74.6%) had a reproduction of symptoms with CCK infusion. The average EF was 88.51%. Final pathology showed chronic cholecystitis in 41 (69.5%) patients, cholesterolosis in 13 (22%), polyp in 2 (3.4%). Thirty-six (61%) patients had complete resolution of symptoms, 9 (15%) patients had partial resolution, and 14 (24%) patients had no change. There was a complete resolution rate of 61% and an improvement rate of 76%.

CONCLUSIONS

In patients with biliary symptoms, negative ultrasound, and elevated EF on HIDA scan (EF > 80%), laparoscopic cholecystectomy led to a significant rate of symptomatic relief. Interestingly, 94% also had unexpected pathologic findings. This disease process requires further analysis, but this could represent a new indication for laparoscopic cholecystectomy in the adult population.
