Prevalence of dyspepsia in patients with cholecystolithiasis: a systematic review and meta-analysis

Unraveling factors associated with textbook outcome after cholecystectomy in patients with uncomplicated cholecystolithiasis: A posthoc analysis of individual data of 1,124 patients

BACKGROUND

A textbook outcome for the management of uncomplicated cholecystolithiasis is the targeted clinical scenario and is characterized by no recurrent biliary colic, absence of surgical and biliary complications, and absence or relief of abdominal pain. The aim of this study was to assess the incidence of textbook outcomes after cholecystectomy and identify associated baseline factors.

METHODS

Patients from 2 Dutch multicenter prospective trials between 2014 and 2019 (SECURE and SUCCESS trial) were included. The primary outcome was the proportion of patients with textbook outcomes after cholecystectomy at 6-month follow-up. Regression analysis was used to identify which factors before surgery were associated with textbook outcomes.

RESULTS

A total of 1,124 patients underwent cholecystectomy. A textbook outcome at 6-month follow-up was reached in 67.9% of patients. Persistent abdominal pain was the main reason for the failure to achieve textbook outcome. Patients who did achieve textbook outcomes more often reported severe pain attacks (89.4% vs 81.7%, P < .001) and/or biliary colic (78.6% vs 68.4%, P < .001) at baseline compared with patients without textbook outcomes. The presence of biliary colic at baseline (odds ratio = 1.56, 95% confidence interval: 1.16-2.09, P = .003) and nausea/vomiting at baseline (odds ratio = 1.33, 95% confidence interval: 1.01-1.74, P = .039) were associated with textbook outcome. The use of non-opioid analgesics (odds ratio = 0.76, 95% confidence interval: 0.58-0.99, P = .043) and pain frequency ≥1/month (odds ratio = 0.56, 95% confidence interval: 0.43-0.73, P < .001) were negatively associated with textbook outcome.

CONCLUSION

Textbook outcome is achieved in two-thirds of patients who undergo cholecystectomy for uncomplicated cholecystolithiasis. Intensity and frequency of pain, presence of biliary colic, and nausea/vomiting at baseline are independently associated with achieving textbook outcomes. A more stringent selection of patients may optimize the textbook outcome rate in patients with uncomplicated cholecystolithiasis.

Persistent and new-onset symptoms after cholecystectomy in patients with uncomplicated symptomatic cholecystolithiasis: A post hoc analysis of 2 prospective clinical trials

BACKGROUND

Laparoscopic cholecystectomy is the gold standard for treating biliary colic in patients with gallstones, but post-cholecystectomy abdominal pain is commonly reported. This study investigates which symptoms are likely to persist and which may develop after a cholecystectomy.

METHODS

Patients from 2 previous prospective trials who underwent laparoscopic cholecystectomy for symptomatic cholecystolithiasis were included. Patients completed questionnaires on pain and gastrointestinal symptoms before surgery and at 6 months follow-up. The prevalence of persistent and new-onset abdominal symptoms was evaluated.

RESULTS

A total of 820 patients received cholecystectomy and were included, 75.4% female (n = 616/820) mean age 49.4 years (standard deviation 13.7). At baseline, 74.1% (n = 608/820) of patients met all criteria for biliary colic. Cholecystectomy successfully resolved biliary colic in 94.8% (n = 327/345) of patients, but 36.5% (n = 299/820) of patients reported persistent abdominal pain after 6 months of follow-up. The prevalence of most abdominal symptoms reduced significantly. Symptoms such as flatulence (17.8%, n = 146/820) or restricted eating (14.5%, n = 119/820) persisted most often. New-onset symptoms were frequent bowel movements (9.6%, n = 79/820), bowel urgency (8.5%, n = 70/820), and new-onset diarrhea (8.4%, 69/820).

CONCLUSION

Postcholecystectomy symptoms are mainly flatulence, frequent bowel movements, and restricted eating. Newly reported symptoms are mainly frequent bowel movements, bowel urgency, and diarrhea. The present findings give clinical guidance in informing, managing, and treating patients with symptoms after cholecystectomy.

Comparison of the epidemiology of disorders of gut-brain interaction in four Latin American countries: Results of The Rome Foundation Global Epidemiology Study

BACKGROUND

In Latin America, there are scarce data on the epidemiology of DGBI. The Rome Foundation Global Epidemiology Study (RFGES) Internet survey included 26 countries, four from Latin America: Argentina, Brazil, Colombia, and Mexico, with a 40.3% prevalence of Rome IV DGBI. We aimed at comparing the prevalence of DGBI and associated factors among these countries.

METHODS

The frequency of DGBI by anatomical region, specific diagnoses, sex, age, diet, healthcare access, anxiety, depression, and HRQOL, were analyzed and compared.

RESULTS

Subjects included Argentina n = 2057, Brazil = 2004, Colombia = 2007, and Mexico = 2001. The most common DGBI were bowel (35.5%), gastroduodenal (11.9%), and anorectal (10.0%). Argentina had the highest prevalence of functional diarrhea (p = 0.006) and IBS-D; Brazil, esophageal, gastroduodenal disorders, and functional dyspepsia; Mexico functional heartburn (all <0.001). Overall, DGBI were more common in women vs. men and decreased with age. Bowel disorders were more common in the 18-39 (46%) vs. 40-64-year (39%) groups. Diet was also different between those with DGBI vs. those without with subtle differences between countries. Subjects endorsing criteria for esophageal, gastroduodenal, and anorectal disorders from Mexico, more commonly consulted physicians for bowel symptoms vs. those from Argentina, Brazil, and Colombia. General practitioners were the most frequently consulted, by Mexicans (50.42%) and Colombians (40.80%), followed by gastroenterologists. Anxiety and depression were more common in DGBI individuals in Argentina and Brazil vs. Mexico and Colombia, and they had lower HRQOL.

CONCLUSIONS

The prevalence of upper and lower DGBI, as well as the burden of illness, psychological impact and HRQOL, differ between these Latin American countries.

Tailoring diagnosis and treatment in symptomatic gallstone disease

BACKGROUND

There is a lack of consensus in selecting patients who do or do not benefit from surgery when patients present with abdominal pain and gallbladder stones are present. This review aimed to give an overview of results from recent trials and available literature to improve treatment decisions in patients with uncomplicated cholecystolithiasis.

METHODS

First, an overview of different symptom criteria for laparoscopic cholecystectomy in patients with uncomplicated cholecystolithiasis is given, based on national and international guidelines. Second, treatment outcomes (absence of biliary colic, pain-free state, biliary and surgical complications) are summarized, with data from three clinical trials. Finally, personal advice for treatment decisions in patients with uncomplicated cholecystolithiasis is provided, based on recent trials, the available literature, and expert opinion.

RESULTS

This review describes different guidelines and criteria sets for uncomplicated cholecystolithiasis, provides an overview of outcomes after cholecystectomy, and advises on treatment decisions in patients with abdominal pain and gallbladder stones. After cholecystectomy, biliary colic is resolved in 95 per cent of patients. However, non-specific abdominal pain persists in 40 per cent. Irritable bowel syndrome and functional dyspepsia significantly increase the risk of persistent pain. Age, previous abdominal surgery, baseline pain score on a visual analogue scale, pain characteristics, nausea, and heartburn are part of the SUCCESS criteria, and are associated with clinically relevant pain reduction after gallbladder removal.

CONCLUSION

The surgical community can now give more personalized advice on surgery to improve care for patients with abdominal pain and uncomplicated cholecystolithiasis.

A survey of functional dyspepsia in 361,360 individuals: Phenotypic and genetic cross-disease analyses

BACKGROUND

Functional dyspepsia (FD) is a common gastrointestinal condition of poorly understood pathophysiology. While symptoms' overlap with other conditions may indicate common pathogenetic mechanisms, genetic predisposition is suspected but has not been adequately investigated.

METHODS

Using healthcare, questionnaire, and genetic data from three large population-based biobanks (UK Biobank, EGCUT, and MGI), we surveyed FD comorbidities, heritability, and genetic correlations across a wide spectrum of conditions and traits in 10,078 cases and 351,282 non-FD controls of European ancestry.

KEY RESULTS

In UK Biobank, 281 diagnoses were detected at increased prevalence in FD, based on healthcare records. Among these, gastrointestinal conditions (OR = 4.0, p < 1.0 × 10^-300 ), anxiety disorders (OR = 2.3, p < 1.4 × 10^-27 ), ischemic heart disease (OR = 2.2, p < 2.3 × 10^-76 ), and infectious and parasitic diseases (OR = 2.1, p = 1.5 × 10^-73 ) showed strongest association with FD. Similar results were obtained in an analysis of self-reported conditions and use of medications from questionnaire data. Based on a genome-wide association meta-analysis of genotypes across all cohorts, FD heritability was estimated close to 5% ( hSNP2  = 0.047, p = 0.014). Genetic correlations indicate FD predisposition is shared with several other diseases and traits (r_g  > 0.344), mostly overlapping with those also enriched in FD patients. Suggestive (p < 5.0 × 10^-6 ) association with FD risk was detected for 13 loci, with 2 showing nominal replication (p < 0.05) in an independent cohort of 192 FD patients.

CONCLUSIONS & INFERENCES

FD has a weak heritable component that shows commonalities with multiple conditions across a wide spectrum of pathophysiological domains. This new knowledge contributes to a better understanding of FD etiology and may have implications for improving its treatment.

Healthcare utilisation of patients with cholecystolithiasis in primary care: a multipractice comparative analysis

OBJECTIVES

To examine general practitioners' (GP) management of cholecystolithiasis and to evaluate persisting abdominal complaints in the years after the diagnosis.

DESIGN

Retrospective analysis of registry data and a subset of individual medical records.

SETTING

Seventeen primary care practices affiliated with the Radboudumc Practice Based Research Network in the Netherlands.

PARTICIPANTS

633 patients with cholecystolithiasis diagnosed between 2012 and 2016.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcome of this study was the healthcare utilisation of patients with cholecystolithiasis diagnosed by the GP in terms of referrals to secondary care, laboratory diagnostics, prescribed medication and the prevalence of concomitant abdominal-related diagnoses in a time interval of 3 years before and 3 years after diagnosis of cholecystolithiasis. For secondary outcomes, electronic medical records were studied from seven practices to assess emergency department visits, operation rates and repeat visits for persistent abdominal symptoms. We compared the non-referred group with the referred group.

RESULTS

In 57% of patients, concomitant abdominal-related diagnoses were recorded besides the diagnosis cholecystolithiasis. In-depth analyses of 294 patients showed a referral rate of 79.3% (n=233); 62.9% (n=185) underwent cholecystectomy. After referral, 55.4% (129/233) returned to the GP for persistent abdominal symptoms. Patients returning after referral were more often treated for another abdominal-related diagnosis before cholecystolithiasis was recorded (51.9% vs 28.8%, p<0.001).

CONCLUSIONS

The majority of patients in general practice with gallstones are referred and undergo cholecystectomy. Patients with concomitant abdominal-related diagnoses are likely to return to their physician. GPs should inform patients about these outcomes to improve the shared decision-making process before gallbladder surgery.

A Clinical Decision Tool for Selection of Patients With Symptomatic Cholelithiasis for Cholecystectomy Based on Reduction of Pain and a Pain-Free State Following Surgery

Importance

There is currently no consensus on the indication for cholecystectomy in patients with uncomplicated gallstone disease.

Objective

To report on the development and validation of a multivariable prediction model to better select patients for surgery.

Design, Setting, and Participants

This study evaluates data from 2 multicenter prospective trials (the previously published Scrutinizing (In)efficient Use of Cholecystectomy: A Randomized Trial Concerning Variation in Practice [SECURE] and the Standardized Work-up for Symptomatic Cholecystolithiasis [Success] trial) collected from the outpatient clinics of 25 Dutch hospitals between April 2014 and June 2019 and including 1561 patients with symptomatic uncomplicated cholelithiasis, defined as gallstone disease without signs of complicated cholelithiasis (ie, biliary pancreatitis, cholangitis, common bile duct stones or cholecystitis). Data were analyzed from January 2020 to June 2020.

Exposures

Patient characteristics, comorbidity, surgical outcomes, pain, and symptoms measured at baseline and at 6 months' follow-up.

Main Outcomes and Measures

A multivariable regression model to predict a pain-free state or a clinically relevant reduction in pain after surgery. Model performance was evaluated using calibration and discrimination.

Results

A total of 1561 patients were included (494 patients in 7 hospitals in the development cohort and 1067 patients in 24 hospitals in the validation cohort; 6 hospitals included patients in both cohorts). In the development cohort, 395 patients (80.0%) underwent cholecystectomy. After surgery, 225 patients (57.0%) reported that they were pain free and 295 (74.7%) reported a clinically relevant reduction in pain. A multivariable prediction model showed that increased age, no history of abdominal surgery, increased visual analog scale pain score at baseline, pain radiation to the back, pain reduction with simple analgesics, nausea, and no heartburn were independent predictors of clinically relevant pain reduction after cholecystectomy. After internal validation, good discrimination was found (C statistic, 0.80; 95% CI, 0.74-0.84) between patients with and without clinically relevant pain reduction. The model had very good overall calibration and minimal underestimation of the probability. External validation indicated a good discrimination between patients with and without clinically relevant pain reduction (C statistic, 0.74; 95% CI, 0.70-0.78) and fair calibration with some overestimation of probability by the model.

Conclusions and Relevance

The model validated in this study may help predict the probability of pain reduction after cholecystectomy and thus aid surgeons in deciding whether patients with uncomplicated cholelithiasis will benefit from cholecystectomy.

Evaluation of a shared decision-making strategy with online decision aids in surgical and orthopaedic practice: study protocol for the E-valuAID, a multicentre study with a stepped-wedge design

BACKGROUND

Inguinal hernia repair, gallbladder removal, and knee- and hip replacements are the most commonly performed surgical procedures, but all are subject to practice variation and variable patient-reported outcomes. Shared decision-making (SDM) has the potential to reduce surgery rates and increase patient satisfaction. This study aims to evaluate the effectiveness of an SDM strategy with online decision aids for surgical and orthopaedic practice in terms of impact on surgery rates, patient-reported outcomes, and cost-effectiveness.

METHODS

The E-valuAID-study is designed as a multicentre, non-randomized stepped-wedge study in patients with an inguinal hernia, gallstones, knee or hip osteoarthritis in six surgical and six orthopaedic departments. The primary outcome is the surgery rate before and after implementation of the SDM strategy. Secondary outcomes are patient-reported outcomes and cost-effectiveness. Patients in the usual care cluster prior to implementation of the SDM strategy will be treated in accordance with the best available clinical evidence, physician's knowledge and preference and the patient's preference. The intervention consists of the implementation of the SDM strategy and provision of disease-specific online decision aids. Decision aids will be provided to the patients before the consultation in which treatment decision is made. During this consultation, treatment preferences are discussed, and the final treatment decision is confirmed. Surgery rates will be extracted from hospital files. Secondary outcomes will be evaluated using questionnaires, at baseline, 3 and 6 months.

DISCUSSION

The E-valuAID-study will examine the cost-effectiveness of an SDM strategy with online decision aids in patients with an inguinal hernia, gallstones, knee or hip osteoarthritis. This study will show whether decision aids reduce operation rates while improving patient-reported outcomes. We hypothesize that the SDM strategy will lead to lower surgery rates, better patient-reported outcomes, and be cost-effective.

Biliary sludge: pathogenesis, etiology and drug therapy

Aim. To evaluate the effectiveness of the use of ursodeoxycholic acid (UDCA) for the treatment of biliary sludge (BS) and to compare the therapeutic effectiveness of the German substance UDCA and generic drugs from other manufacturers. Materials and methods. The study involved 65 patients diagnosed with BS (K80.8). To assess the severity of BS, ultrasound of the gallbladder was performed before treatment, after 1, 3, 6 months during therapy, as well as an assessment of its contractility. All patients were randomized into 2 groups. Patients of the main group received UDCA Ursofalk (Germany) at a dose of 10 mg/kg for at least 6 months. Patients in the comparison group received UDCA (another manufacturer) at a dose of 10 mg/kg for at least 6 months. Results. After 3 months of follow-up, the number of patients with dissolved sludge in the main group was 87.1%, while in the comparison group 50%. In 71% of patients, the normalization of the lean volume of the gallbladder was noted, and in the comparison group only in 47.1%. After 6 months of follow-up, complete resolution of BS in the main group was observed in 93.5% of cases, and in the comparison group in 73.6% of cases. Conclusion. As a result of the study, the high effectiveness of Ursofalk during oral litolysis in patients with stage I GI (BS) in the first 3 months of therapy, as well as the normalization of the contractile function of the gallbladder, were noted.

Surgical referral for cholecystectomy in patients with atypical symptoms

BACKGROUND

Cholelithiasis referrals often present with concomitant or isolated atypical symptoms such as reflux, bloating, or epigastric pain. We sought to identify the impact of preoperative symptomatology of atypical or dyspepsia-type biliary colic on operative and non-operative clinical outcomes.

METHODS

A retrospective review of patients referred for gallstone disease from 2014 to 2018 at a single institution in Los Angeles County was performed.

RESULTS

Of 746 patients evaluated for gallstone disease, 87.4% (n = 652) underwent cholecystectomy - 90.8% (n = 592) had symptom resolution postoperatively whereas 9.2% (n = 60) did not. Over half presented with concomitant atypical and/or dyspepsia symptoms (n = 411). Heartburn/reflux was significantly associated with unresolved symptoms postoperatively (OR 2.1,1.0-4.4, p = 0.04). Overall, 11.1% (n = 83) of all 746 patients and 20.2% of patients with atypical and/or dyspepsia symptoms improved with medical management of gastritis or Helicobacter pylori triple therapy pre/post-operatively.

CONCLUSION

Atypical biliary colic and/or dyspepsia is associated with unresolved symptoms following cholecystectomy. Such patients may benefit from H. pylori testing or PPI trial prior to cholecystectomy.

Functional Dyspepsia and Irritable Bowel Syndrome are Highly Prevalent in Patients With Gallstones and are Negatively Associated With Outcomes After Cholecystectomy: A Prospective, Multicentre, Observational Study (PERFECT - Trial)

OBJECTIVE

To determine the prevalence of functional dyspepsia (FD) and irritable bowel syndrome (IBS) in patients eligible for cholecystectomy and to investigate the association between presence of FD/IBS and resolution of biliary colic and a pain-free state.

SUMMARY BACKGROUND DATA

More than 30% of patients with symptomatic cholecystolithiasis reports persisting pain post-cholecystectomy. Co-existence of FD/IBS may contribute to this unsatisfactory outcome.

METHODS

We conducted a multicentre, prospective, observational study (PERFECT-trial). Patients ≥18 years with abdominal pain and gallstones were included at five surgical outpatient clinics between 01/2018-04/2019. Follow-up was six months. Primary outcomes were prevalence of FD/IBS, and the difference between resolution of biliary colic and pain-free state in patients with and without FD/IBS. FD/IBS was defined by the Rome IV criteria, biliary colic by the Rome III criteria, and pain-free by an Izbicki Pain Score ≤10 and visual analogue scale ≤4.

RESULTS

We included 401 patients with abdominal pain and gallstones (assumed eligible for cholecystectomy), mean age 52 years, 76% females. Of these, 34.9% fulfilled criteria for FD/IBS. 64.1% fulfilled criteria for biliary colic and 74.9% underwent cholecystectomy, with similar operation rates in patients with and without FD/IBS. Post-cholecystectomy, 6.1% of patients fulfilled criteria for biliary colic, with no significant difference between those with and without FD/IBS at baseline (4.9% vs. 8.6%, p = 0.22). Of all patients, 56.8% was pain-free after cholecystectomy, 40.7% of FD/IBS-group vs. 64.4% of no FD/IBS-group, p < 0.001.

CONCLUSION

One-third of patients eligible for cholecystectomy fulfil criteria for FD/IBS. Biliary colic is reported by only a few patients post-cholecystectomy, whereas non-biliary abdominal pain persists in >40%, particularly in those with FD/IBS pre-cholecystectomy. Clinicians should take these symptom-dependent outcomes into account in their shared decision making process.
