Age and incidence of occult pancreaticobiliary reflux in patients with benign gallbladder diseases.

BACKGROUND: Occult pancreaticobiliary reflux (OPBR) has a significant correlation with diseases of the gallbladder and biliary system. This study examined the incidence of OPBR by age in patients with benign gallbladder diseases. METHODS: We assessed 475 patients with benign gallbladder diseases who underwent surgery at Shanghai East Hospital from December 2020 to December 2021. Bile samples collected during surgery were tested for amylase. Patients with bile amylase >110 U/L (n = 64) were classified as the OPBR group; the rest (n = 411) as controls. RESULTS: Of the participants, 375 had gallbladder stone (GS), 170 had gallbladder polyp (GP), and 49 had gallbladder adenomyomatosis (GA). The OPBR group was generally older, with OPBR incidence increasing with age, peaking post-45. Rates by age were: 4.9% (<35), 5.2% (35-44), 20.7% (45-54), 22.5% (55-64) and 17.6% (≥65), mainly in GS patients. ROC analysis for predicting OPBR by age yielded an area under the curve of 0.656, optimal cut-off at 45 years. Logistic regression indicated age > 45, GP, male gender, and BMI ≥ 24 kg*m-2 as independent OPBR predictors in GS patients. Based on these variables, a predictive nomogram was constructed, and its effectiveness was validated using the ROC curve, calibration curve and decision curve analysis (DCA). Further stratification revealed that among GS patients ≤ 45, concurrent GA was an OPBR risk; for > 45, it was GP and male gender. CONCLUSIONS: The incidence of OPBR in GS patients is notably influenced by age, with those over 45, especially males without GP, being at heightened risk.

Elevated serum triglyceride levels may be a key independent predicting factor for gallbladder cancer risk in gallbladder stone disease patients: a case-control study.

BACKGROUND: Gallbladder stone diseases (GSD) is a main risk factor of gallbladder cancer (GBC). This study aimed to reveal their bridge to metabolic syndrome. MATERIAL/METHOD: The clinical and experimental data of 2210 GBC patients, from 3524 Chinese patients, in our hospital from Jan. 2009 to Dec. 2020 were summarized. The metabolic syndrome indexes, influencing factors for both GBC and GSD, were analyzed by unconditional logistic regression in this case-control study. RESULT: There were significantly higher morbidity of GBC in the overall, GSD and non-GSD with hypertriglyceridemia patients versus non-hypertriglyceridemia ones (P < 0.001, all). In GSD patients, univariate regression showed a significantly positive correlation between serum triglyceride (TG), low density lipoprotein cholesterol (LDL-c), fasting insulin (FINS) levels, Homeostasis model assessment-insulin resistance (HOMA-IR), female being, body mass index, hypertriglyceridemia and hazard of GBC with GSD (P < 0.001, all), and a significantly negative correlation to systolic pressure (SBP), diastolic pressure (DBP), hypertension and high-density lipoprotein cholesterol (HDL-c), fasting blood glucose (FBG) (P < 0.05, all); multivariate regression showed that serum triglyceride was the most significantly positive factor associated to GBC (P < 0.001, all) among the hazard factors including serum TG, LDL-c levels, HOMA-IR. In non-GSD ones, multivariate regression showed that HOMA-IR was the most significantly positive factor associated to GBC among the hazard factors including serum TG, LDL-c levels, HOMA-IR, female being, while DM had a significantly inversion negative association (P < 0.001). CONCLUSION: We found initially that elevated serum TG levels could be the most remarkable independent predicting factor for GBC risk with GSD, while insulin resistance might act as the first one in non-GSD. More importantly, we advocated initially the sharp rise of serum TG levels as the potential of a candidate diagnostic or prognostic biomarker of GBC with GSD. TRIAL REGISTRATION: The study may be performed in accordance with the ethical standards provided by the responsible committee of our institution (First Affiliated Hospital of Xi'an Jiaotong University. XJTU1AF2020LSK-160) at which the work was carried out an in accordance with the Declaration of Helsinki. The ethics committee of our institution strictly comply with the requirements of ICH-GCP、GCP and relevant regulations to construct, operate and implement operating procedures.

Feasibility of transgastric endoscopic gallbladder-preserving surgery for benign gallbladder diseases (with video).

BACKGROUND: With the increasing realization of the importance of gallbladder function, choledochoscopic gallbladder-preserving surgery has been advocated for benign gallbladder diseases. However, limited information is available regarding the use of endoscopic gallbladder-preserving surgery (EGPS) for patients with benign gallbladder diseases. The aim of this study was to evaluate the feasibility of EGPS for benign gallbladder diseases. METHODS: Between June 2020 and January 2021, 22 patients with gallbladder stones and/or gallbladder polyps were treated with EGPS. The main outcome measures included the rate of complications, residual gallbladder stones, and gallbladder stone recurrence. RESULTS: In this study, transgastric EGPS was successfully performed in 22 patients (13 female, 9 male) with benign gallbladder diseases, and included 8 cases of multiple gallstones, 4 cases of gallbladder polyps with gallstones, 6 cases of multiple gallbladder polyps, 2 cases of single gallstone, and 2 case of singe gallbladder polyp. The median time of transgastric EGPS was 118 min. During hospitalization, 4 patients suffered localized peritonitis (4/22, 18.2%), and these patients successfully recovered after conservative medical treatment. None of the patients experienced massive bleeding, delayed bleeding, diffuse peritonitis, or any other serious complications. During the median follow-up of 4 months, 1 patient suffered residual gallstone, while no gallstone recurrence or deaths related to transgastric EGPS occurred in any patients. CONCLUSIONS: Transgastric EGPS appears to be a feasible treatment method in selected patients with benign gallbladder diseases. However, as it is a new technique, further studies are needed to explore the long-term effectiveness of transgastric EGPS.

Assessment of postoperative common bile duct stones after endoscopic extraction and subsequent cholecystectomy.

BACKGROUND: Common bile duct stones (CBDSs) occasionally cause serious diseases, and endoscopic extraction is the standard procedure for CBDS. To prevent biliary complications, cholecystectomy is recommended for patients who present with gallbladder (GB) stones after endoscopic CBDS extraction. However, CBDS can occasionally recur. To date, the occurrence of CBDS after endoscopic CBDS extraction and subsequent cholecystectomy is not fully understood. Hence, the current study aimed to evaluate the incidence of postoperative CBDSs. METHODS: This retrospective observational study included consecutive patients who underwent postoperative endoscopic retrograde cholangiography after endoscopic CBDS extraction and subsequent cholecystectomy between April 2012 and June 2021 at our institution. After endoscopic CBDS extraction, a biliary plastic stent was inserted to prevent obstructive cholangitis. Endoscopic retrograde cholangiography was performed to evaluate postoperative CBDSs after cholecystectomy until hospital discharge. The outcomes were the incidence of postoperative CBDSs and CBDSs/sludge. Moreover, the predictive factors for postoperative CBDSs were evaluated via univariate and multivariate analyses. RESULTS: Of eligible 204 patients, 52 patients (25.5%) presented with postoperative CBDSs. The incidence rate of CBDS/sludge was 36.8% (n = 75). Based on the univariate analysis, the significant predictive factors for postoperative CBDSs were ≥ 6 CBDSs, presence of cystic duct stones, and ≥ 10 GB stones (P < 0.05). Moreover, male sex and < 60-mm minor axis in GB might be predictive factors (P < 0.10). Based on the multivariate analysis, ≥ 6 CBDSs (odds ratio = 6.65, P < 0.01), presence of cystic duct stones (odds ratio = 4.39, P < 0.01), and ≥ 10 GB stones (odds ratio = 2.55, P = 0.01) were independent predictive factors for postoperative CBDSs. CONCLUSIONS: The incidence of postoperative CBDS was relatively high. Hence, patients with predictive factors for postoperative CBDS must undergo imaging tests or additional endoscopic procedure after cholecystectomy.

An inverse association of weight and the occurrence of asymptomatic gallbladder stone disease in hypercholesterolemia patients: a case-control study.

BACKGROUND: Despite the fact that the majority of gallstones formed in the gallbladder are mainly composed of cholesterol, as they are formed from cholesterol-supersaturated bile, and hypercholesterolemia is a common metabolic disorder, which is closely related to cardiac, hepatic, renal and other oxidative damage inflammation and necrosis, there is still no consensus regarding the contribution of blood serum lipids in the pathogenesis of gallbladder stone disease (GSD). This study aimed to investigate the relationship between hypercholesterolemia and the risk of new-onset asymptomatic GSD, and to determine the prevalence of factors associated with new-onset asymptomatic GSD in patients with hypercholesterolemia. METHODS: In this study, 927 Chinese patients with new-onset asymptomatic gallstone disease and 845 healthy controls were enrolled starting from August 2012. Patients were matched for age, gender, race, occupation, systolic blood pressure, diastolic blood pressure, and fasting blood glucose levels (FBG). Body mass index (BMI), nonalcoholic fatty liver disease (NAFLD) and serum lipids indexes were compared and the relationships between BMI, blood lipid and gallbladder stone hazards were examined by logistic multivariate regression models. RESULTS: The result showed a significantly higher morbidity with GSD in hypercholesterolemia than non-hypercholesterolemia patients (Χ2 = 17.211, P < 0.001). Of hypercholesterolemia patients, low density lipoprotein (OR = 1.493, P = 0.029) and NAFLD (OR = 2.723, P = 0.022) were significant risk factors for GSD, while being male (OR = 0.244, P = 0.033), weight (OR = 0.961, P = 0.022), high density lipoprotein (OR = 0.305, P < 0.001), and FBG (OR = 0.687, P = 0.034) were significantly negatively correlated with GSD in univariate analysis. Multivariate logistic regression indicated weakly positive correlations with NAFLD (OR = 3.284, P = 0.054), and significant negative correlations with weight (OR = 0.930, P = 0.018), HDL-c (OR = 0.144, P < 0.001), and GSD. CONCLUSION: Hypercholesterolemia acts as an independent risk factor for new-onset asymptomatic GSD, while obesity and NAFLD are synergistic factors. Interestingly, it is first reported that elevated weight was inversely associated with GSD in patients with hypercholesterolemia. The results of this study suggest that effective control of hyperlipidemia is of greater significance than weight loss, which might make the situation worse, in the prevention of GSD in obese patients with hyperlipidemia.

Sex difference of the predictive value of BMI, waist circumference and percentage body fat mass for gallstone disease.

Gallstone disease (GSD) represents a significant health burden and is reported to be strongly related to obesity. This study examined the effect of sex on the association of BMI, waist circumference (WC) and percentage body fat mass (%FM) with GSD. We enrolled 15 671 middle-aged Taiwanese adults undergoing a physical check-up at a health examination centre. Multiple logistic regression analysis was conducted to identify the association of BMI, WC and %FM with the presence of GSD. AUC of the receiver-operating characteristic (ROC) curves were calculated for BMI, WC and %FM to compare their respective ability to correctly classify patients with GSD. From our findings, GSD prevalence was 8·1 % in men and 6·3 % in women. The percentage of markedly increased obesity indicators was significantly higher in patients with GSD than in those without GSD. Multivariate analysis showed that all obesity indicators were significant predictors of the presence of GSD in women after adjustment. In men, only BMI and WC were significantly associated with the presence of GSD. In the ROC curve analysis, BMI and WC were the best predictors of GSD risk in women and men, respectively. The obesity indicators better predicted the presence of GSD in women than in men. In conclusion, the best obesity indicator of GSD risk differed by sex. In addition to body weight, fat mass and central obesity were associated with GSD risk in women. In men, central obesity may play a more important role in predicting GSD risk.

[Clinical evaluation of gallbladder and common bile duct stones treated though cholecystostomy tube].

Objective: To investigate the efficacy, feasibility and safety of treatment of gallbladder and common bile duct stones treated through cholecystostomy tube. Methods: The clinical data of 17 patients with gallbladder and common bile duct stones treated through cholecystostomy tube from January 2012 to December 2016 was analyzed retrospectively. Results: Seventeen patients were successfully treated with percutaneous transhepatic gallbladder (PTGD), and 88.2% (15/17) patients had clinical symptom relief. There was no complication happened after PTGD and fistula expansion. All the stones were removed and there was 11.7% (2/17) of gallbladder bleeding, 5.9% (1/17) of pancreatitis, and 5.9% (1/17) of hyperamylasemia after stones extraction. The patients had gone through an average treatment period of 87.8±16.0 days, hospitalization of 5.5±0.6 times and 43.3±4.5 days, cost of 60.0±8.0 thousand, 6.9±0.9 operations, 1.4±0.6 stone extraction operations with the average time of 58.4±21.2 min. The duodenal papillary balloon dilatation rate was 82.4% (14/17). Conclusion: The treatment through cholecystostomy tube is an effective, safe and feasible technique for gallbladder and common bile duct stones. However, there are many shortcomings such as long treatment cycle, large number of hospitalization and operations, difficult operation and high cost.

Radiation effect on cathodoluminescence and thermoluminescence emission of Ca-rich oxalates from the human body.

The radiation effect of luminescence emission of Ca-rich oxalate biogenic materials (gallbladder and renal calculi) and a commercial standard sample (CaC2 O4 ·H2 O) is reported. The samples were characterized by environmental scanning electron microscopy, energy dispersive X-ray spectroscopy, thermogravimetric and differential thermal analyses, display complex cathodoluminescence (CL) and thermoluminescence (TL) glow emissions. CL spectra (in the UV-infrared range) displayed non-well defined peaks, and exhibited emission at: (i) higher energies (300-490 nm) mainly associated with non-bridging oxygen hole centers, oxygen-deficient centers and peroxy intrinsic defects, regardless of the sample; and (ii) higher, narrow and sharp wavebands, in the red region, probably induced by the presence of traces of Sm3+ (4 G5/2 →6 H9/2 transition) and/or Tb3+ (5 D4 →7 F3 transition) only for mineral-like materials in the human body. The UV-blue TL emission showed low-intensity maxima in which it was possible to distinguish at least four groups of components in each sample.

Natural history of asymptomatic gallbladder stones in clinic without beds: A long-term prognosis over 10 years.

BACKGROUND: Several studies have explored the long-term prognosis of patients with asymptomatic gallbladder stones. These reports were primarily conducted in facilities equipped with beds for addressing symptomatic cases. AIM: To report the long-term prognosis of patients with asymptomatic gallbladder stones in clinics without bed facilities. METHODS: We investigated the prognoses of 237 patients diagnosed with asymptomatic gallbladder stones in clinics without beds between March 2010 and October 2022. When symptoms developed, patients were transferred to hospitals where appropriate treatment was possible. We investigated the asymptomatic and survival periods during the follow-up. RESULTS: Among the 237 patients, 214 (90.3%) remained asymptomatic, with a mean asymptomatic period of 3898.9279 ± 46.871 d (50-4111 d, 10.7 years on average). Biliary complications developed in 23 patients (9.7%), with a mean survival period of 4010.0285 ± 31.2788 d (53-4112 d, 10.9 years on average). No patient died of biliary complications. CONCLUSION: The long-term prognosis of asymptomatic gallbladder stones in clinics without beds was favorable. When the condition became symptomatic, the patients were transferred to hospitals with beds that could address it; thus, no deaths related to biliary complications were reported. This finding suggests that follow-up care in clinics without beds is possible.

Clinical efficacy of laparoscopic cholecystectomy combined with endoscopic papillary balloon dilation in treatment of gallbladder stones with common bile duct stones: A retrospective study.

BACKGROUND: The incidence of cholelithiasis has been on the rise in recent years, but the choice of procedure is controversial. AIM: To investigate the efficacy of laparoscopic cholecystectomy (LC) combined with endoscopic papillary balloon dilation (EPBD) in patients with gallbladder stones (GS) with common bile duct stones (CBDS). METHODS: The clinical data of 102 patients with GS combined with CBDS were selected for retrospective analysis and divided into either an LC + EPBD group (n = 50) or an LC + endoscopic sphincterotomy (EST) group (n = 52) according to surgical methods. Surgery-related indexes, postoperative recovery, postoperative complications, and expression levels of inflammatory response indexes were compared between the two groups. RESULTS: Total surgical time, stone free rate, rate of conversion to laparotomy, and successful stone extraction rate did not differ significantly between the LC + EPBD group and LC + EST group. Intraoperative hemorrhage, time to ambulation, and length of hospitalization in the LC + EPBD group were lower than those of the LC + EST group (P < 0.05). The rate of total complications of the two groups was 9.80% and 17.65%, respectively, and the difference was not statistically significant. No serious complications occurred in either group. At 48 h postoperatively, the expression levels of interleukin-6, tumor necrosis factor-α, high-sensitivity C-reactive protein, and procalcitonin were lower in the LC + EPBD group than in the LC + EST group (P < 0.05). At 3 d postoperatively, the expression levels of aspartate transaminase, alanine transaminase, and total bilirubin were lower in the LC + EPBD group than in the LC + EST group (P < 0.05). CONCLUSION: LC combined with EPBD and LC combined with EST are both effective procedures for the treatment of GS with CBDS, in which LC combined with EPBD is beneficial to shorten the patient's hospitalization time, reduce the magnitude of elevated inflammatory response indexes, and promote postoperative recovery.

Osteopontin (SPP1) expression on gallstone formation in rabbits fed with a lithogenic diet.

Objective: This research was designed to assess the influence of the administration of a lithogenic diet, hydrogen peroxide, and vitamin AD3E on rabbits' gallstone formation and to envisage the expression of osteopontin (OPN) in their hepatic tissues. Materials and Methods: Twenty-four healthy local mature rabbits of both genders were divided into four equal groups. At the end of the feeding period, samples of blood were taken from all rabbits after they had fasted overnight to estimate the serum lipid profile. And some of the hepatic tissue has been preserved at -28°C for molecular analysis and gene expression. Results: The gallstones were formed 100% in the GIII and 50% in the GIV. The mRNA OPN expression showed a significant increase in the GIII when compared with other groups. In Groups III and II, the serum levels of total cholesterol, Triglyceride, L-C, low-density lipoprotein-choles, and VLDL-C were significantly increased when compared with GI, while in GIII, the serum level of high-density lipoprotein-cholesterol was significantly decreased when compared with GI. Conclusion: It was concluded that the expression of the mRNA OPN was increased in the hepatic tissue of gallstone-formed rabbits.

Nomogram for predicting gallbladder stone in patients with type 2 diabetes mellitus: a retrospective study in the Chinese population.

OBJECTIVE: The purpose of this study is to explore the risk factors of gallbladder stone (GBS) in patients with type 2 diabetes mellitus (T2DM) and also develop a simple-to-use nomogram for GBS in patients with T2DM. METHODS: This study retrospectively analyzed 2243 patients with T2DM hospitalized in Peking University International Hospital from January 2017 to August 2022. According to the results of colour Doppler ultrasonic examinations, the patients were divided into two groups. RESULTS: (1) Compared with the non-GBS group, the GBS group was older (p < 0.05), and the diabetes duration in the GBS group was longer (p < 0.05). The proportion of overweight and obese people in the GBS group was significantly higher than that in the non-GBS group (p < 0.05, respectively). The proportion of patients with diabetic nephropathy (DN) and diabetic peripheral neuropathy (DPN) was higher in the GBS group (p < 0.05, respectively). (2) Logistic regression showed that age, body mass index (BMI), diabetes duration, total cholesterol (TC), triglycerides (TG), alanine aminotransferase (ALT), DN, and DPN were independent risk factors for GBS (p < 0.05, respectively). (3) The area under the curve (AUC) of the nomogram for GBS was 0.704 (95% CI 0.656, 0.748), with a specificity of 90.34%, a sensitivity of 55.38%, and an accuracy of 86.83%. CONCLUSION: The nomogram is accurate to a certain degree and provides a clinical basis for predicting the incidence of GBS in patients with T2DM, which has a certain predictive value.

A Review of the Management of Cholelithiasis at Buraydah Central Hospital in the Qassim Region, Saudi Arabia: A Cross-Sectional Study.

Cholelithiasis is the most common cause of gastroenterological hospitalization. Given this significant risk, perfectly managing cholelithiasis is crucial to reduce hospitalization. Unfortunately, we have not found a study on a review of the management of cholelithiasis in Saudi Arabia. Therefore, we aim to evaluate cholelithiasis concerning demographic features, presentation symptoms, predisposing risk factors, laboratory features, complications, and outcomes in the Qassim region. This cross-sectional study of all patients with a radiological diagnosis of gallstones, whether symptomatic or not, was diagnostic in 2022. The researchers fielded a preformed data collection sheet for each patient from the hospital system. Data obtained were entered into a spreadsheet and analyzed using SPSS Statistics version 23.0 (IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp.). A total of 526 patients were included in the study. Most patients (116, 22.1%), were aged 38-42. The finding also indicated that most patients were females (397, 75.5%), while males were only 129 (24.5%). The study also found that the difference between women and men presenting complaints of fat intolerance and right shoulder pain was statistically significant. Women were 100 (84%) and men were 19 (16%) for fat intolerance, while for right shoulder pain, women were 50 (89.3%) and men were six (10.7%). The p-values were 0.014 and 0.011, respectively. Further, there was a statistically significant difference in terms of the complaints presented by the patients between the complicated and non-complicated cases of abdominal pain (p=0.001), nausea (p=0.001), vomiting (p=0.001), change in urine and stool color (p=0.001), and right shoulder pain (p=0.001), among other complaints (p=0.001). The study concludes that most patients affected by cholelithiasis are individuals in the middle age group, with women being more affected by the disease than men. Further, among the individuals affected by the disease, the majority of them were overweight and obese. On the other hand, the study concludes that the majority of patients who suffer more from cholelithiasis are affected mainly by other associated diseases such as hypertension, hypothyroidism, and diabetes mellitus. In conclusion, many factors may contribute to gallstone formation and the outcome of the disease and surgery. Therefore, the study recommends that health workers offer tailored education, especially targeting the highlighted factors found in this study, to create awareness of disease control measures in the general population. Also, keep in mind these factors when dealing with patients who complain of abdominal pain.

The Correlation between Islet ß Cell Secretion Function and Gallbladder Stone Disease: A Retrospective Study Based on Chinese Patients with Newly Diagnosed Type 2 Diabetes Mellitus.

BACKGROUND: This study aimed to analyze the correlation between islet ß cell function and gallbladder stone (GBS) in newly diagnosed type 2 diabetes mellitus (T2DM) patients. METHODS: A total of 438 newly diagnosed T2DM patients in Peking University International Hospital from January 2017 to August 2022 were retrospectively analyzed and divided into a non-GBS group and a GBS group. RESULTS: (1) The homeostasis model assessment of the insulin resistance (HOMA-IR) of the GBS group was higher than that of the non-GBS group (p < 0.05), while the homeostasis model assessment of ß cell (HOMA-ß), disposition index (DI0), and Matsuda index of the GBS group were lower than those of the non-GBS group (all p < 0.05). (2) For male patients, HOMA-IR is an independent risk factor for GBS (OR = 2.00, 95% CI:1.03, 3.88, p < 0.05), and the Matsuda index value is a protective factor for GBS (OR = 0.76, 95% CI:0.60, 0.96, p < 0.05). For female patients, HOMA-IR is an independent risk factor for GBS (OR = 2.80, 95% CI:1.03, 7.58, p < 0.05) and the Matsuda index value is a protective factor for GBS (OR = 0.59, 95% CI:0.39, 0.90, p < 0.05). (3) For male patients, the area under curve (AUC) for predicting GBS was 0.77 (95% CI 0.67, 0.87), with a specificity of 75.26%, a sensitivity of 80.00%, and an accuracy of 75.64%. For female patients, the AUC for predicting GBS was 0.77 (95% CI 0.63, 0.88), with a specificity of 79.63%, a sensitivity of 71.43%, and an accuracy of 78.69%. CONCLUSIONS: Insulin resistance may be an independent risk factor for the incidence of GBS in patients with newly diagnosed T2DM, both male or female, which provides a new clinical basis and research direction for the prevention and treatment of GBS in patients with T2DM. This study has established a predictive model of GBS in T2DM and found it to be accurate, thus representing an effective tool for the early prediction of GBS in patients with T2DM.

Eight-Centimeter Gallbladder Stone Post-Roux-en-Y Gastric Bypass: A Case Report.

Cholelithiasis occurs when a stone forms in the gallbladder; when symptoms develop, the condition is termed symptomatic cholelithiasis. The correlation between bariatric surgery and post-operative symptomatic cholelithiasis has long been established. Presented is a case of a 56-year-old female status post-Roux-en-Y gastric bypass who developed symptomatic cholelithiasis and subsequently underwent cholecystectomy with the removal of an 8-centimeter (cm) gallbladder stone. This case report explores the benefits and limitations of watchful waiting versus prophylactic concomitant cholecystectomy among bariatric surgery patients, noting the difference between the bariatric sleeve and bypass anatomy for managing biliary complications.

Association of METS-IR index with prevalence of gallbladder stones and the age at the first gallbladder stone surgery in US adults: A cross-sectional study.

Objective: The purpose of this study was to assess the correlation between the metabolic score for insulin resistance (METS-IR) index and gallbladder stoneprevalence in US adults, as well as the age at first gallbladder stone surgery. Methods: A logistic regression analysis, subgroup analysis, and dose-response curve were computed for participants in the 2017-2018 National Health and Nutrition Examination Survey (NHANES) to assess the relationship between the METS-IR index and gallbladder stone prevalence and age at first surgery for gallbladder stones. Results: This study ultimately included 9452 participants aged >20 years, of whom 534 self-reported a history of gallbladder stones, and after adjusting for all confounders, each unit increase in METS-IR index was associated with a 3.3% increase in gallbladder stone prevalence (OR= 1.033, 95% CI: 1.0258, 1.0403) along with an earlier age at first gallbladder stone surgery 0.26 years (ß= -0.26, 95% CI: -0.35, -0.17), stratified analysis showed that increased METS-IR index was associated with increased prevalence of gallbladder stones in all subgroups, and the dose-response curve showed a positive linear correlation between METS-IR index and prevalence of gallbladder stones, while a negative linear correlation was observed between increased METS-IR index and age at first gallbladder stone There was a negative linear correlation between age at surgery. Conclusion: The METS-IR index has been positively associated with gallbladder stone prevalence, thereby contributing to age at first surgery for gallbladder stones. However, the causal relationship between the METS-IR and gallbladder stones cannot be concluded.

Comparison of Patient Outcomes and Safety between Overlapping and Nonoverlapping Surgeries in Patients Undergoing Laparoscopic Common Bile Duct Exploration.

PURPOSE: Overlapping surgery or double-booking is a vital yet disputed issue in healthcare field. However, safety of the overlapping surgery during laparoscopic common bile duct exploration (LCBDE) remains unclear. This study aimed to assess the clinical outcomes and safety of overlapping surgery during laparoscopic cholecystectomy and LCBDE for gallbladder and common bile duct stones (CBDS). MATERIAL AND METHODS: This study retrospectively reviewed 2736 laparoscopic cholecystectomy and LCBDE surgeries during 2013-2020. One thousand, two hundred eighty patients underwent LCBDE through cystic duct, including 867 receiving overlapping procedures, while 1456 underwent LCBDE through laparoscopic choledochotomy (LC), including 981 who underwent overlapping procedures. Data regarding patient sex, age, body mass index, the American Society of Anesthesiology grade, comorbidities, preoperative liver function test, previous upper abdominal surgery, presence of acute cholecystitis, cholangitis, pancreatitis, or jaundice, common bile duct (CBD) or CBDS diameter, CBDS number, LCBDE operation time, procedure duration, length of stay, stone clearance, CBD closure methods, conversion to open surgery, and complications were collected. RESULTS: Differences in demographics and clinical variables between both groups were not significant, and the unadjusted outcomes were comparable, except for the total procedure duration (transcystic: p < .001; LC: p < .001). After adjusting for demographics and clinical variables, overlapping surgery showed an extended total surgical procedure duration (transcystic: standardized coefficient = 0.084, p = .004; LC: standardized coefficient = 0.072, p = .015). Other effects of overlapping surgery were also comparable. CONCLUSIONS: Overlapping surgery in laparoscopic cholecystectomy and LCBDE was safe at our institution. However, the association of patient outcomes with overlapping laparoscopic cholecystectomy and LCBDE should be further investigated.

Management of Gallstones and Acute Cholecystitis in Patients with Liver Cirrhosis: What Should We Consider When Performing Surgery?

Acute cholecystitis and several gallbladder stone-related conditions, such as impacted common bile duct stones, cholangitis, and biliary pancreatitis, are common medical conditions in daily practice. An early cholecystectomy or drainage procedure with delayed cholecystectomy is the current standard of treatment based on published clinical guidelines. Cirrhosis is not only a condition of chronically impaired hepatic function but also has systemic effects in patients. In cirrhotic individuals, several predisposing factors, including changes in the bile acid composition, increased nucleation of bile, and decreased motility of the gallbladder, contribute to the formation of biliary stones and the possibility of symptomatic cholelithiasis, which is an indication for surgical treatment. In addition to these predisposing factors for cholelithiasis, systemic effects and local anatomic consequences related to cirrhosis lead to anesthesiologic risks and perioperative complications in cirrhotic patients. Therefore, the treatment of the aforementioned biliary conditions in cirrhotic patients has become a challenging issue. In this review, we focus on cholecystectomy for cirrhotic patients and summarize the surgical indications, risk stratification, surgical procedures, and surgical outcomes specific to cirrhotic patients with symptomatic cholelithiasis.

The Safety and Necessity of Concomitant Cholecystectomy During Bariatric Surgery in Patients with Obesity: a Systematic Review and Meta-analysis.

Concomitant cholecystectomy (CCE) during bariatric surgery(BS)in patients with obesity remains a matter of debate. This study aimed to estimate the safety and necessity of CCE during BS. This study analyzed the postoperative complications in patients who underwent CCE during BS and subsequent cholecystectomy rate following BS. Patients in CCE and BS-only groups had no difference in mortality. A higher postoperative complication rate was observed in the CCE group (OR 1.2, 95% CI 1.1-1.3) (p < 0.001) but no severe complication in both groups. Following BS, gallstone patients had a higher subsequent cholecystectomy rate than those with normal gallbladders (OR 2.47%, 95% CI 1.5-4.1) (p < 0.001). Concomitant cholecystectomy increased the rates of postoperative complications during BS. We only recommend CCE for documented gallstones rather than for normal gallbladder.

Best evidence topic: Does the presence of a large gallstone carry a higher risk of gallbladder cancer?

A best evidence topic has been constructed using a described protocol. The three-part question addressed was: In a patient with symptomatic gallstone disease does the presence of a large sized gallstone associated with a higher risk of gallbladder cancer? Using the reported search, 3876 papers were found. 6 studies were deemed to be suitable to answer the question. The outcome assessed was the relationship between the presence of large sized gallstones and the risk of gallbladder cancer. It appears from the current available evidence that there is a strong association of a large sized gallstones and gallbladder cancer. Larger stones (>3 cm) have the greatest risk to develop gallbladder cancer, especially in symptomatic gallstone disease patients. Authors recommend special care for this patient's group and to warrant cholecystectomy when the clinical condition allows.
