Cholelithiasis and cholecystectomy increase the risk of gastroesophageal reflux disease and Barrett's esophagus.

Background: Cholelithiasis or cholecystectomy may contribute to the development of gastroesophageal reflux disease (GERD), Barrett's esophagus (BE), and esophageal adenocarcinoma (EAC) through bile reflux; however, current observational studies yield inconsistent findings. We utilized a novel approach combining meta-analysis and Mendelian randomization (MR) analysis, to assess the association between them. Methods: The literature search was done using PubMed, Web of Science, and Embase databases, up to 3 November 2023. A meta-analysis of observational studies assessing the correlations between cholelithiasis or cholecystectomy, and the risk factors for GERD, BE, and EACwas conducted. In addition, the MR analysis was employed to assess the causative impact of genetic pre-disposition for cholelithiasis or cholecystectomy on these esophageal diseases. Results: The results of the meta-analysis indicated that cholelithiasis was significantly linked to an elevated risk in the incidence of BE (RR, 1.77; 95% CI, 1.37-2.29; p < 0.001) and cholecystectomy was a risk factor for GERD (RR, 1.37; 95%CI, 1.09-1.72; p = 0.008). We observed significant genetic associations between cholelithiasis and both GERD (OR, 1.06; 95% CI, 1.02-1.10; p < 0.001) and BE (OR, 1.21; 95% CI, 1.11-1.32; p < 0.001), and a correlation between cholecystectomy and both GERD (OR, 1.04; 95% CI, 1.02-1.06; p < 0.001) and BE (OR, 1.13; 95% CI, 1.06-1.19; p < 0.001). After adjusting for common risk factors, such as smoking, alcohol consumption, and BMI in multivariate analysis, the risk of GERD and BE still persisted. Conclusion: Our study revealed that both cholelithiasis and cholecystectomy elevate the risk of GERD and BE. However, there is no observed increase in the risk of EAC, despite GERD and BE being the primary pathophysiological pathways leading to EAC. Therefore, patients with cholelithiasis and cholecystectomy should be vigilant regarding esophageal symptoms; however, invasive EAC cytology may not be necessary.

Cholelithiasis, Gut Microbiota and Bile Acids after Bariatric Surgery-Can Cholelithiasis Be Prevented by Modulating the Microbiota? A Literature Review.

BACKGROUND: Cholelithiasis is one of the more common complications following bariatric surgery. This may be related to the rapid weight loss during this period, although the exact mechanism of gallstone formation after bariatric surgery has not been fully elucidated. METHODS: The present literature review focuses on risk factors, prevention options and the impact of the gut microbiota on the development of gallbladder stones after bariatric surgery. RESULTS: A potential risk factor for the development of cholelithiasis after bariatric surgery may be changes in the composition of the intestinal microbiota and bile acids. One of the bile acids-ursodeoxycholic acid-is considered to reduce the concentration of mucin proteins and thus contribute to reducing the formation of cholesterol crystals in patients with cholelithiasis. Additionally, it reduces the risk of both asymptomatic and symptomatic gallstones after bariatric surgery. Patients who developed gallstones after bariatric surgery had a higher abundance of Ruminococcus gnavus and those who did not develop cholelithiasis had a higher abundance of Lactobacillaceae and Enterobacteriaceae. CONCLUSION: The exact mechanism of gallstone formation after bariatric surgery has not yet been clarified. Research suggests that the intestinal microbiota and bile acids may have an important role in this.

Bouveret Syndrome: Etiology, Clinical Presentation, Differential Diagnosis, Complications, and Treatment Options.

Bouveret syndrome is one of the complications of gallstone disease possibly fatal, which proposes the presence of a large stone obliterating the lumen of the duodenum or stomach because of the formation of a bilioenteric fistula. This review article, therefore, plans to review the causes, patient characteristics, diagnostic workup, associated conditions, and treatment of Bouveret syndrome. A literature search was also performed through scientific databases such as Scopus, Google Scholar, and PubMed concerning articles related to Bouveret syndrome written by different authors. The terms employed for the search were bilioduodenal fistula, Bouveret syndrome, gastric outlet obstruction, and gallstone ileus. Both case reports and systematic reviews that were written in the English language and published between the years 2000 and 2024 were considered. Finally, the review establishes the relevant concerns surrounding the diagnosis of Bouveret syndrome, focusing on the diagnosing issues. It emphasises the need for some specialities' involvement and focuses on the importance of endoscopic intervention. For patients, endoscopy remains the first line of treatment, while surgery is necessary in cases where conservative methods cannot be used. The article also focuses on new approaches to treating the conditions, such as percutaneous gallbladder stone dissolution. Latterly, further developments in minimally invasive surgery pertain to refining methods, including endoscopic removal and lithotripsy, to improve the survival rate of patients. Further investigation is required, especially regarding the administration schedule in relation to this disorder and goals that can reduce mortality and morbidity, especially in elderly patients with comorbid diseases.

Intestinal obstruction induced by gallstone migration through unusual location of a cholecystogastric fistula: A rare case report.

INTRODUCTION: Gallstone ileus is a rare condition resulting from cholelithiasis, associated with the formation of a fistula between the gallbladder and the intestinal tract. It is responsible for less than 0.1 % of cases of mechanical bowel obstruction. PRESENTATION OF CASE: A 54-year-old male with hypertension presented with symptoms of intestinal obstruction, including inability to pass stool, anorexia, abdominal pain, vomiting, and oliguria. Physical examination revealed epigastric tenderness and a distended abdomen without jaundice. Laboratory tests indicated mild anemia. The patient initially refused any surgical interventions, so he was placed on conservative treatment for 24 h. Subsequently, an emergency exploratory open laparotomy was performed, revealing a gallstone causing small bowel obstruction. A constricted ileal loop, 15 cm in length, with stone impaction was resected, and an end-to-end anastomosis was performed. A cholecystogastric fistula was identified and repaired, and a retrograde cholecystectomy was performed. The patient recovered without complications. DISCUSSION: Gallstone ileus occurs when a fistula develops between the gallbladder and the intestinal tract. Notably, the presence of a fistula connecting the gallbladder and stomach ranges from 0 % to 13.3 %. Cholecystoenteric fistulas (CEFs) typically occur in elderly women in their seventh or eighth decade of life. Diagnosis often relies on CT scanning, and surgical intervention remains the primary treatment. Interestingly, despite improved awareness and imaging techniques, some cases are still discovered incidentally during surgery. CONCLUSION: This case highlights the diagnostic and therapeutic challenges posed by gallstone ileus, and emphasizes the importance of considering gallstone-related disorders in differential diagnoses for acute abdominal obstruction.

Cholecystogastric fistula: A case report and review of the literature.

INTRODUCTION: Cholecystogastric fistula is an abnormal communication between the gallbladder and the stomach, it is a rare complication of chronic cholethiasis. Preoperative diagnosis is difficult as patients often present with non-specific symptoms. CASE PRESENTATION: A 63-year-old female presented to the outpatient clinic with symptomatic cholelithiasis. Physical examination was unremarkable. Laboratory investigations, including complete blood count (CBC) and liver function test (LFT), were within normal limits. Upper abdominal ultrasound revealed hepatomegaly and gallbladder contraction with multiple gallstones. Intraoperative exploration during laparoscopic cholecystectomy revealed adhesions with cholecystogastric fistula, necessitating meticulous dissection, fistula excision, and primary closure. Postoperatively, the patient recovered uneventfully, with a negative methylene blue leak test allowing early oral intake. Discharged home in stable condition, subsequent follow-up showed resolution of symptoms, and histopathological examination confirmed absence of neoplastic changes. DISCUSSION: Optimal surgical management of cholecystogastric fistula is debatable, laparoscopic surgery have led to improved outcomes in the management of these cases. Utilizing which approach should be determined based on the clinical scenario for each patient and the surgeon experience. CONCLUSION: Cholecystogastric fistula is a rare complication of chronic cholethiasis. Preoperative diagnosis requires high index of suspicion. Complete laparoscopic management is safe.

Demographic and Clinicopathological Spectrum of Gallbladder Carcinoma in a Tertiary Care Centre in Jharkhand: A Retrospective Study.

Introduction Gallbladder carcinoma is a rare but aggressive cancer of adults that affects females more than males. Its occurrence is more common in the regions of South America and Asia. Chronic inflammation and cholelithiasis are frequently associated risk factors of gallbladder carcinoma. The incidental discovery of a gallbladder carcinoma during cholecystectomy, gross or microscopic examination of the unsuspected gallbladder specimens is termed incidental gallbladder carcinoma (IGBC). Considering the lack of extensive studies on gallbladder carcinoma in the Eastern region of India, especially in Jharkhand, this study has been done to present the demographic and clinicopathological characteristics of gallbladder carcinoma in this region. Methods A retrospective and descriptive study was done at Rajendra Institute of Medical Sciences (RIMS), Ranchi, a tertiary care center in Jharkhand. The study sample comprised 2386 gall bladder cases received in the Department of Pathology over five years, from December 2018 to December 2023. Results Of 2368 specimens, 25 cases (n=25) were reported as primary gallbladder carcinoma. The female-to-male ratio was 4:1. Pain was the most common complaint by the patients. Of the 25 cases, 12 were suspected intra-operatively or diagnosed microscopically (IGBC). Most showed a mass at the neck. In six cases, no gross mass/lesion was seen. Cholelithiasis is present in 19/25 cases. Most cases showed adenocarcinoma (not otherwise specified). Out of the adenocarcinoma cases, most were well differentiated. At the time of diagnosis, most were at the pT2 stage. Twelve cases of IGBC were found. Eight out of 12 IGBC were early-stage carcinoma when diagnosed. Conclusion Twenty-five cases of gallbladder carcinoma were diagnosed in the last five years in our center, with 19 (76%) of them associated with cholelithiasis. Twelve (48%) of the cases were incidentally diagnosed either preoperatively or during gross/microscopic examination, and eight (66%) of those were discovered early, out of which five (62.5%) were observed to be in the T1b stage. At this stage, there is a diversion from the general surgical management of gallbladder carcinoma for a better prognosis. This underscores the significance of routine histopathological examination of gallbladder specimens, even if there is no preoperative suspicion of gallbladder carcinoma.

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.

Pediatric gallstone disease-Management difficulties in clinical practice.

BACKGROUND: Gallstone disease (GD) is no longer an exclusive condition of adulthood, and its prevalence is increasing in pediatric age. The management and the extent of the etiological investigation of GD in children and adolescents remains controversial. This study aimed to analyze the difficulties in the work-up and management of pediatric GD patients. METHODS: A retrospective study performed in a single tertiary center enrolled sixty-five patients with GD followed from January 2014 to June 2021. Patients were categorized conveniently according to their age at diagnosis: Group A (<10years, n=35) and Group B (≥10years, n=30). We analyzed demographic, clinical and laboratory data, ultrasonographic findings at presentation, therapeutics and complications. RESULTS: Symptoms were more frequent in patients >10years old (p=0.001). Cholecystectomy was performed in 31 patients (47.7%). A multivariate regression logistic model identified the age >10years (OR=6.440, p=0.005) and underlying entities (OR=6.823, p=0.017) as independent variables to perform surgery. Spontaneous resolution of GD was more common in children <2years old. A multivariate regression logistic model showed a trend for those >10years old to develop more complications. Two out of 18 patients were diagnosed with ABCB4 gene mutations in heterozygosity. CONCLUSIONS: Decision-making on cholecystectomy remains challenging in asymptomatic patients. Identifying predictive factors for the development of complications has proven difficult. However, we found a trend toward the development of complications in individuals older than 10years.

Ultraprocessed food consumption and risk of gallstone disease: analysis of 3 prospective cohorts.

BACKGROUND: Majority of dietary intake in United States adults comes from ultraprocessed foods (UPFs), which have been linked to several adverse health outcomes. Gallstone disease is highly prevalent and constitutes a significant burden to the United States health system but remains understudied. OBJECTIVES: This study aimed to investigate the association between UPF consumption and incident gallstone disease risk. METHODS: In this analysis, 44,149 males in the Health Professionals' Follow-up Study (HPFS: 1986-2022), 71,145 females in the Nurses' Health Study (NHS: 1986-2021), and 90,932 females in the NHS II (1991-2021) were prospectively followed. Dietary intake was quadrennially assessed with semiquantitative food frequency questionnaires and used to identify UPFs. The primary outcome was defined as cholecystectomy. Cox proportional hazards model was used to estimate adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs). RESULTS: Baseline median age was 54 y in HPFS, 53 y in NHS, and 36 y in NHS II. We identified 32,374 incident gallstone disease cases over 5,077,059 person-years. Participants in the highest UPF quintile had a higher incidence of gallstone disease than those in the lowest quintile (aHR: 1.29; 95% CI: 1.24, 1.36; P < 0.001). Incremental risk of incident gallstone disease was 2.8% per daily serving (95% CI: 2.4%, 3.2%; P < 0.001). This risk was driven by sugar-sweetened beverages and artificially sweetened beverages on UPF subgroup analyses. The proportion of risk mediated by obesity was 12.8% (95% CI: 7.7%, 20.5%; P < 0.001) in HPFS, 14.3% (95% CI: 10.4%, 19.4%; P < 0.001) in NHS, and 39.4% (95% CI: 31.2%, 48.1%; P < 0.001) in NHS II. The partial population attributable risk was estimated at 15.9% (95% CI: 13.4%, 18.3%). CONCLUSIONS: UPF consumption is associated with a higher risk of gallstone disease, particularly consumption of sugar-sweetened beverages and artificially sweetened beverages. A substantial proportion of this risk is potentially mediated by obesity in younger females.

Association of education with cholelithiasis and mediating effects of cardiometabolic factors: A Mendelian randomization study.

BACKGROUND: Education, cognition, and intelligence are associated with cholelithiasis occurrence, yet which one has a prominent effect on cholelithiasis and which cardiometabolic risk factors mediate the causal relationship remain unelucidated. AIM: To explore the causal associations between education, cognition, and intelligence and cholelithiasis, and the cardiometabolic risk factors that mediate the associations. METHODS: Applying genome-wide association study summary statistics of primarily European individuals, we utilized two-sample multivariable Mendelian randomization to estimate the independent effects of education, intelligence, and cognition on cholelithiasis and cholecystitis (FinnGen study, 37041 and 11632 patients, respectively; n = 486484 participants) and performed two-step Mendelian randomization to evaluate 21 potential mediators and their mediating effects on the relationships between each exposure and cholelithiasis. RESULTS: Inverse variance weighted Mendelian randomization results from the FinnGen consortium showed that genetically higher education, cognition, or intelligence were not independently associated with cholelithiasis and cholecystitis; when adjusted for cholelithiasis, higher education still presented an inverse effect on cholecystitis [odds ratio: 0.292 (95%CI: 0.171-0.501)], which could not be induced by cognition or intelligence. Five out of 21 cardiometabolic risk factors were perceived as mediators of the association between education and cholelithiasis, including body mass index (20.84%), body fat percentage (40.3%), waist circumference (44.4%), waist-to-hip ratio (32.9%), and time spent watching television (41.6%), while time spent watching television was also a mediator from cognition (20.4%) and intelligence to cholelithiasis (28.4%). All results were robust to sensitivity analyses. CONCLUSION: Education, cognition, and intelligence all play crucial roles in the development of cholelithiasis, and several cardiometabolic mediators have been identified for prevention of cholelithiasis due to defects in each exposure.

Biliary anatomic variant and recurrent acute cholecystitis, cholelithiasis in gallbladder remnant in patient with autosomal dominant polycystic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited renal disorder. ADPKD is not only associated with progression of renal disease, but also several hepatobiliary manifestations. This report is of a 49-year-old female with recurrent cholelithiasis and cholecystitis following subtotal cholecystectomy in the context of aberrant biliary anatomy and ADPKD. There were significant adhesions obscuring the cystic duct, necessitating the second cholecystectomy be performed open. The right posterior hepatic duct was adhered to the gallbladder wall and was perforated while attempting to remove the gallbladder remnant. The duct was repaired over a T-tube, without any subsequent biliary leak. The cystic duct was hugely dilated and impacted with stones down to the junction with the common bile duct, which were evacuated, and the cystic duct was oversewn along with the remnant of the gallbladder wall. The recovery course was unremarkable.

Hepatic artery pseudoaneurysm: three case reports and literature review.

Laparoscopic surgery is extensively applied in the treatment of hepatobiliary diseases. Hepatic artery pseudoaneurysm (HAP) is a rare complication following hepatic biliary surgery through laparoscopy. The clinical manifestations of HAP are diverse and can be fatal. Given its severity, rapid assessment and management are crucial to ensuring a good prognosis. Here, we report three cases of HAP; two underwent laparoscopic surgery due to cholelithiasis, and another caused by trauma. The first case exhibited a pseudoaneurysm involving the distal portion of the right hepatic artery main trunk. The second patient had a pseudoaneurysm at the bifurcation of the left and right hepatic arteries. The third case involved a patient with a pseudoaneurysm involving a branch of the right hepatic artery. The main clinical manifestations of all three cases were bleeding from the biliary tract (the first two cases showed postoperative bleeding in the T-tube, while the third case exhibited gastrointestinal bleeding). The final diagnosis was obtained through digital subtraction angiography. The three patients underwent successful transcatheter arterial embolization operation and a follow-up revealed they were disease-free and alive. This article aims to highlight a rare complication of laparoscopic hepatobiliary surgery and share our experience in early diagnosis and treatment of HAP.

Biliary complications associated with weight loss, cholelithiasis and choledocholithiasis.

Biliary complications like cholelithiasis and choledocholithiasis are more common in bariatric surgery patients due to obesity and rapid weight loss. Patients with a body mass index > 40 face an eightfold risk of developing cholelithiasis. Post-bariatric surgery, especially after laparoscopic Roux-en-Y gastric bypass (LRYGB), 30% of patients develop biliary disease due to rapid weight loss. The aim of this review is to analyze the main biliary complications that occur after bariatric surgery and its management. A review of the literature was conducted mainly from 2010 up to 2023 with regard to biliary complications associated with bariatric patients in SciELO, PubMed, and MEDLINE. Patients undergoing LRYGB have a higher incidence (14.5%) of symptomatic calculi post-surgery compared to those undergoing laparoscopic sleeve gastrectomy at 4.1%. Key biliary complications within 6 to 12 months post-surgery include: Cholelithiasis: 36%; Biliary colic/dyskinesia: 3.86%; Acute cholecystitis: 0.98%-18.1%; Chronic cholecystitis: 70.2%; Choledocholithiasis: 0.2%-5.7% and Pancreatitis: 0.46%-9.4%. Surgeons need to be aware of these complications and consider surgical treatments based on patient symptoms to enhance their quality of life.

Association between cholelithiasis, cholecystectomy, and risk of breast and gynecological cancers: Evidence from meta-analysis and Mendelian randomization study.

BACKGROUND: Observational studies have shown that cholelithiasis and cholecystectomy are associated with the risk of breast cancer (BC) and gynecological cancers, but whether these relationships are causal has not been established and remains controversial. METHODS: Our study began with a meta-analysis that synthesized data from prior observational studies to examine the association between cholelithiasis, cholecystectomy, and the risk of BC and gynecological cancers. Subsequently, a two-sample Mendelian randomization (MR) analysis was conducted utilizing genetic variant data to investigate the potential causal relationship between cholelithiasis, cholecystectomy, and the aforementioned cancers. RESULTS: The results of the meta-analysis demonstrated a significant association between cholecystectomy and the risk of BC (risk ratio [RR] = 1.04, 95% confidence interval [CI]: 1.01-1.06, p = 0.002) and endometrial cancer (EC) (RR = 1.26, 95% CI: 1.02-1.56, p = 0.031). Conversely, no significant association was observed between cholelithiasis and the risk of BC, EC, and ovarian cancer. The MR analysis revealed no discernible causal connection between cholelithiasis and overall BC (p = 0.053), as well as BC subtypes (including estrogen receptor-positive/negative). Similarly, there was no causal effect of cholecystectomy on BC risk (p = 0.399) and its subtypes. Furthermore, no causal associations were identified between cholelithiasis, cholecystectomy, and the risk of gynecological cancers (ovarian, endometrial, and cervical cancer [CC]) (all p > 0.05). CONCLUSION: This study does not support a causal link between cholelithiasis and cholecystectomy and an increased risk of female cancers such as breast, endometrial, ovarian, and CC.

Factors associated with postoperative nausea and vomiting after laparoscopic cholecystectomy at the National Referral Hospital, Bhutan: a cross-sectional study.

INTRODUCTION: Postoperative nausea and vomiting (PONV) are common distressing symptoms experienced after laparoscopic cholecystectomy. We report the rate, and the factors associated with postoperative nausea and vomiting, the patterns of prophylactic antiemetic prescription, and the anesthetic techniques used among patients who underwent laparoscopic cholecystectomy at the Jigme Dorji Wangchuck (JDW) National Referral Hospital, Bhutan. METHODS: A cross-sectional study was conducted at the JDW National Referral Hospital, from January to December 2018. All the patients who underwent laparoscopic cholecystectomy under general anesthesia were included in the study. The demographic variables, premedication, induction agents, muscle relaxants, inhalational agents for maintenance, opioid and adjuvant analgesics, the reversal agents used, and the occurrence of PONV within 24 h were recorded. Data were analyzed using SPSS (version 23). Continuous variables were compared using a t-test or Mann-Whitney test, categorical variables were tested using chi-square or Fisher's exact tests. Binary logistic regression analysis was performed to determine the factors associated with postoperative nausea and vomiting. RESULTS: 190 patients underwent laparoscopic cholecystectomy under general anesthesia. The rate of PONV after laparoscopic cholecystectomy was 31.1% (59/190). Over half (53.7%, 102/190) of the study population were within 21-40 years of age, over 80% (157/190) were female, and 2/3rd were overweight and obese. The most frequently used premedication was ranitidine (39%, 34/87) and metoclopramide (31%, 27/87). More than half (57.4%, 109/190) of the patients received morphine as an opioid analgesic before induction. Sodium thiopentone was a commonly used induction agent (65.8%, 125/190). Succinylcholine and atracurium were mostly preferred muscle relaxants. Isoflurane and air were the most used inhalational anesthetic agents for the maintenance of anesthesia. Ondansetron was the most preferred anti-emetics during the intraoperative period. Previous history of motion sickness (OR 5.8, 95%CI 2.9-11.2, p < 0.001), and use of sodium thiopental (OR 4.1, 95%CI 1.9-9.1, p < 0.001) were independent risk factors for PONV. The use of antiemetics (OR 0.1, 95%CI 0.0-0.4, p = 0.002), propofol (OR 0.2, 95%CI 0.1-0.5, p < 0.001), adjuvant analgesic paracetamol (OR 0.4, 95%CI 0.2-0.8, p = 0.026), and adequate hydration with IV fluids (OR 0.9, 95%CI 0.9-1.0, p = 0.042) were preventive factors for PONV. CONCLUSION: The rate of PONV after laparoscopic cholecystectomy was high. History of motion sickness and use of sodium thiopental for induction were independent risk factors of PONV. The use of multimodal prophylactic antiemetics was robust and superior to monotherapy in preventing PONV. This finding re-emphasizes the need for risk stratification and appropriate use of antiemetics and anesthetic agents to prevent PONV.

Percutaneous transhepatic choledochoscopy in the management of hepatolithiasis: a narrative review.

Background and Objective: From the 1980s and continuing into the 21st century, percutaneous transhepatic choledoscopy (PTCS) has been increasingly used in the clinical management of cholelithiasis. However, when compared to conventional minimally invasive techniques such as endoscopic retrograde cholangiopancreatography (ERCP), PTCS is characterized by greater invasiveness and a higher rate of complications. As a result, PTCS is frequently used as a supplementary treatment option. Nevertheless, it plays a unique and indispensable role in addressing hepatolithiasis. In this study, to facilitate safer clinical applications and gain a deeper understanding of PTCS-related complications, we conducted a comprehensive examination of these complications. Methods: Research studies related to PTCS were reviewed in PubMed, Web of Science, and China National Knowledge Infrastructure (CNKI) (year range, 1952-2024). There was no restriction on language. The occurrence and management of complications at various steps of PTCS were examined and compared with those of first-line minimally invasive treatments via a tabular method. Additionally, we evaluated the feasibility of using PTCS in the context of intrahepatic bile duct stones. Key Content and Findings: Information on the types, incidence, and treatment of complications of PTCS was extracted in this review. A total of 5,923 results were retrieved, of which 41 were excluded. The reason for exclusion was that the article was a meeting comment. The findings indicate that PTCS plays an important role in the treatment of biliary tract diseases. Conclusions: Although PTCS is frequently used as an adjunctive therapeutic approach, its distinct utility in treating intrahepatic bile duct stones remains difficult to replace. Thus, a deeper understanding of PTCS-related complications, coupled with ongoing advancements in instrumentation, could significantly enhance the efficiency of minimally invasive gallstone management.

The Multifaceted Impact of Gallstones: Understanding Complications and Management Strategies.

Gallstones, or cholelithiasis, represent a prevalent gastrointestinal disorder characterized by the formation of calculi within the gallbladder. This review aims to provide a comprehensive analysis of the complications associated with gallstones, with a focus on their pathophysiology, clinical manifestations, diagnostic methodologies, and management strategies. Gallstone-related complications encompass a broad spectrum, including biliary colic, acute cholecystitis, choledocholithiasis, acute pancreatitis, and cholangitis. The pathogenesis of these complications primarily involves biliary obstruction and subsequent infection, leading to significant morbidity and potential mortality. Diagnostic evaluation of gallstone complications employs various imaging techniques, such as ultrasonography, magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP), each with distinct advantages and limitations. Therapeutic approaches are discussed, ranging from conservative management with pharmacotherapy and bile acid dissolution agents to interventional procedures like extracorporeal shock wave lithotripsy (ESWL) and percutaneous cholecystostomy. Surgical management, particularly laparoscopic cholecystectomy, remains the gold standard for definitive treatment. Additionally, advancements in endoscopic techniques, including endoscopic sphincterotomy (EST) and cholangioscopy, are highlighted. This review synthesizes current research findings and clinical guidelines, aiming to enhance the understanding and management of gallstone-related complications among healthcare professionals, thereby improving patient outcomes and reducing the burden of this common ailment.

Antimicrobial glycoprotein 2 (GP2) in gallstones, bile fluid and peribiliary glands of patients with primary sclerosing cholangitis.

BACKGROUND: Glycoprotein-2 (GP2) IgA is a predictor of disease severity in primary sclerosing cholangitis (PSC). We examined GP2's occurrence in the biliary tract, the site of inflammation. METHODS: GP2 was analyzed using ELISA, immunoblotting, mass spectrometry, and immunohistochemistry. The samples included: 20 bile and 30 serum samples from PSC patients, 23 bile and 11 serum samples from patients with gallstone disease (GD), 15 bile samples from healthy individuals undergoing liver-donation surgery (HILD), 20 extracts of gallstones (GE) obtained during cholecystectomy, and 101 blood-donor sera. RESULTS: Biliary GP2 concentrations were significantly higher in patients with PSC and GD than in HILD (p < 0.0001). Serum GP2 levels were similar in PSC and GD patients, and controls, but lower than in bile (p < 0.0001). GP2 was detected in all 20 GEs. Mass spectrometry identified GP2 in the bile of 2 randomly selected GD and 2 PSC patients, and in none of 2 HILD samples. GP2 was found in peribiliary glands in 8 out of 12 PSC patients, showing morphological changes in acinar cells, but not in GD-gallbladders. CONCLUSIONS: GP2 is present in bile of PSC and GD patients. It is synthesized in the peribiliary glands of PSC patients, supporting a pathogenic role for biliary GP2 in PSC.

Laparoscopic cholecystectomy versus conservative management for adults with uncomplicated symptomatic gallstones: the C-GALL RCT.

Background: Gallstone disease is a common gastrointestinal disorder in industrialised societies. The prevalence of gallstones in the adult population is estimated to be approximately 10-15%, and around 80% remain asymptomatic. At present, cholecystectomy is the default option for people with symptomatic gallstone disease. Objectives: To assess the clinical and cost-effectiveness of observation/conservative management compared with laparoscopic cholecystectomy for preventing recurrent symptoms and complications in adults presenting with uncomplicated symptomatic gallstones in secondary care. Design: Parallel group, multicentre patient randomised superiority pragmatic trial with up to 24 months follow-up and embedded qualitative research. Within-trial cost-utility and 10-year Markov model analyses. Development of a core outcome set for uncomplicated symptomatic gallstone disease. Setting: Secondary care elective settings. Participants: Adults with symptomatic uncomplicated gallstone disease referred to a secondary care setting were considered for inclusion. Interventions: Participants were randomised 1: 1 at clinic to receive either laparoscopic cholecystectomy or observation/conservative management. Main outcome measures: The primary outcome was quality of life measured by area under the curve over 18 months using the Short Form-36 bodily pain domain. Secondary outcomes included the Otago gallstones' condition-specific questionnaire, Short Form-36 domains (excluding bodily pain), area under the curve over 24 months for Short Form-36 bodily pain domain, persistent symptoms, complications and need for further treatment. No outcomes were blinded to allocation. Results: Between August 2016 and November 2019, 434 participants were randomised (217 in each group) from 20 United Kingdom centres. By 24 months, 64 (29.5%) in the observation/conservative management group and 153 (70.5%) in the laparoscopic cholecystectomy group had received surgery, median time to surgery of 9.0 months (interquartile range, 5.6-15.0) and 4.7 months (interquartile range 2.6-7.9), respectively. At 18 months, the mean Short Form-36 norm-based bodily pain score was 49.4 (standard deviation 11.7) in the observation/conservative management group and 50.4 (standard deviation 11.6) in the laparoscopic cholecystectomy group. The mean area under the curve over 18 months was 46.8 for both groups with no difference: mean difference -0.0, 95% confidence interval (-1.7 to 1.7); p-value 0.996; n = 203 observation/conservative, n = 205 cholecystectomy. There was no evidence of differences in quality of life, complications or need for further treatment at up to 24 months follow-up. Condition-specific quality of life at 24 months favoured cholecystectomy: mean difference 9.0, 95% confidence interval (4.1 to 14.0), p < 0.001 with a similar pattern for the persistent symptoms score. Within-trial cost-utility analysis found observation/conservative management over 24 months was less costly than cholecystectomy (mean difference -£1033). A non-significant quality-adjusted life-year difference of -0.019 favouring cholecystectomy resulted in an incremental cost-effectiveness ratio of £55,235. The Markov model continued to favour observation/conservative management, but some scenarios reversed the findings due to uncertainties in longer-term quality of life. The core outcome set included 11 critically important outcomes from both patients and healthcare professionals. Conclusions: The results suggested that in the short term (up to 24 months) observation/conservative management may be a cost-effective use of National Health Service resources in selected patients, but subsequent surgeries in the randomised groups and differences in quality of life beyond 24 months could reverse this finding. Future research should focus on longer-term follow-up data and identification of the cohort of patients that should be routinely offered surgery.

The C-GALL study assessed the benefits, in terms of symptoms, quality of life and costs, of cholecystectomy versus observation (conservative management: by the patient and general practitioner that might include dietary advice and pain management and surgery if needed). Four hundred and thirty-four patients with symptomatic gallstones were randomly allocated surgery or conservative management. The main symptom of ongoing bodily pain and some other quality-of-life measures were assessed over the next 2 years using postal questionnaires. After 2 years, 70% of those allocated to surgery had been operated on and 37% of the observation group either had an operation or were waiting for one. There was no difference in bodily pain or overall quality of life between the groups. However, participants in the surgery group reported fewer ongoing problems related to their gallstone disease or after surgery than those in the conservative management group. Surgery was, however, more costly than conservative management. The C-GALL study has shown that for some patients, a conservative management approach may be a sufficient and less costly way of managing their gallstone symptoms rather than going straight on the waiting list for surgery. More research is needed to identify which patients benefit most from surgery.

Pancreatic Pseudocyst and Obesity: Video Case Report of Management with the One-Stage Procedure.

Reports of pancreatic pseudocyst drainage during metabolic bariatric surgery are extremely rare. Our patient is a 38-year-old female suffering from obesity grade IV and presents a persistent symptomatic pancreatic pseudocyst 8 months after an episode of acute biliary pancreatitis. After an extensive evaluation and considering other treatment options, our multidisciplinary team and the patient decided to perform a one-stage procedure consisting of laparoscopic cystogastrostomy, cholecystectomy, and one-anastomosis gastric bypass. After bringing the patient to the operating room, the surgeon performed an anterior gastrostomy to access the stomach's posterior wall, followed by a 6-cm cystogastrostomy on both the stomach's posterior wall and the cyst. Next, a cholecystectomy which involved dissecting the triangle of Calot was performed. Then, an 18-cm gastric pouch using a 36-Fr calibration tube was created. The cystogastrostomy was left in the remaining stomach. Finally, gastrojejunal anastomosis is done. The patient's postoperative course proceeded smoothly, leading to her home discharge on the third postoperative day. At the 1-year follow-up, the patient had lost 56 kg and was symptom-free; a computer tomography scan showed that the pancreatic pseudocyst had resolved. This case shows a video of a successful laparoscopic cystogastrostomy, cholecystectomy, and one-anastomosis gastric bypass (OAGB) used to treat persistent abdominal pain and obesity grade IV. We also conduct a bibliographic review.
