The Treatment of Gallstone Disease

Research on the prognostic value of adjusting intraperitoneal three-dimensional quality evaluation mode in laparoscopic cholecystectomy patients

BACKGROUND

Benign gallbladder diseases have become a high-prevalence condition not only in China but also worldwide. The main types of benign gallbladder diseases include gallbladder polyps, acute and chronic cholecystitis, and gallstones, with gallstones being the most common, accounting for over 70% of cases. Although the mortality rate of benign gallbladder diseases is low, they carry obvious potential risks. Studies have shown that an increased incidence of benign gallbladder diseases can increase the risk of cardiovascular diseases and gallbladder cancer, resulting in a substantial disease burden on patients and their families.

AIM

To assess the medical utility of the Configuration-Procedure-Consequence (CPC) three-dimensional quality evaluation model in modulating the prognosis of laparoscopic cholecystectomy patients.

METHODS

A total of 98 patients who underwent laparoscopic cholecystectomy in our hospital from February 2020 to January 2022 were selected as the subjects. According to the random number table method, they were divided into a study group and a control group, with 49 patients in each group. The control group received routine perioperative care, while the study group had the addition of the CPC three-dimensional quality evaluation. The postoperative recovery-related indicators (time to first flatus, time to oral intake, time to ambulation, hospital stay), stress indicators (cortisol and adrenaline levels), distinctions in anxiety and depression status, and the incidence of perioperative complications were compared.

RESULTS

The time to first flatus, time to oral intake, time to ambulation, and hospital stay of the study group patients were obviously lower than those of the control group patients, with statistical significance (P < 0.05). On the 1st day after admission, there were no obvious distinctions in cortisol and adrenaline levels in blood samples, as well as in the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores between the study group and the control group (P > 0.05). However, on the 3rd day after surgery, the cortisol and adrenaline levels, as well as SAS and SDS scores of the study group patients, were obviously lower than those of the control group patients (P < 0.05). The study group had 2 cases of incisional infection and 1 case of pulmonary infection, with a total incidence of complications of 6.12% (3/49), which was obviously lower than the 20.41% (10/49) in the control group (P < 0.05).

CONCLUSION

Implementing the CPC three-dimensional quality evaluation model for patients undergoing laparoscopic cholecystectomy can help accelerate their perioperative recovery process, alleviate perioperative stress symptoms, mitigate anxiety, depression, and other adverse emotions, and to some extent, reduce the incidence of perioperative complications.

Lost gallstones during laparoscopic cholecystectomy as a common but underestimated complication-case report and review of the literature

Introduction

Laparoscopic cholecystectomy (LC) represents one of the most commonly performed routine abdominal surgeries. Nevertheless, besides bile duct injury, problems caused by lost gallstones represent a heavily underestimated and underreported possible late complication after LC.

Methods

Case report of a Clavien-Dindo IVb complication after supposedly straightforward LC and review of all published case reports on complications from lost gallstones from 2000-2022.

Case Report

An 86-year-old patient developed a perihepatic abscess due to lost gallstones 6 months after LC. The patient had to undergo open surgery to successfully drain the abscess. Reactive pleural effusion needed additional drainage. Postoperative ICU stay was 13 days. The patient was finally discharged after 33 days on a geriatric remobilization ward and died 12 months later due to acute cardiac decompensation.

Conclusion

Intraabdominal abscess formation due to spilled gallstones may present years after LC as a late complication. Surgical management in order to completely evacuate the abscess and remove all spilled gallstones may be required, which could be associated with high morbidity and mortality, especially in elderly patients. Regarding the overt underreporting of gallstone spillage in case of postoperative gallstone-related complications, focus need be put on precise reporting of even apparently innocuous complications during LC.

CLINICAL AND PATHOLOGIC FINDINGS IN IGUANIDS WITH SODIUM URATE CHOLELITHIASIS

Four green iguanas (Iguana iguana) and one blue iguana (Cyclura lewisi) from five facilities were diagnosed with sodium urate cholelithiasis. One case was diagnosed antemortem via ultrasonography, and the iguana underwent a choledochotomy for treatment. The other four cases were identified at necropsy. Pathologic hepatic and biliary changes were present in four of the five cases at necropsy. Histologically, four iguanas had hepatic fibrosis, three had bile duct hyperplasia, and one had cholangiohepatitis and pancreaticocholedochitis. Two iguanas had pathologic renal changes. This is the first report of sodium urate cholelithiasis in reptiles. This case series highlights the potential significant clinical disease caused by sodium urate cholelithiasis and the importance of biliary system evaluation. Further investigation is recommended to explore the pathogenesis of reptilian sodium urate cholelith formation.

Sodium butyrate restricts neutrophils migration and NETs formation through reducing macrophage-derived CXCL16 in calculous cholecystitis

Background

Neutrophil extracellular traps (NETs) havebeen demonstrated to initiate gallstone formation. Cholecystitis is a common complication of gallstones. As short-chain fatty acids (SCFAs), Butyrate acid has anti-inflammatory effects and alleviates cholesterol gallstones. However, the role of Butyrate acid in NETs of calculous cholecystitis and the molecular mechanism remains unclear. The effect of Sodium butyrate on neutrophil migration and NETs formation involved in macrophages polarization and exosomalCXCL16 in calculous cholecystitis was explored in our study.

Methods

The number of neutrophils and NETs, macrophages polarization and exosomal CXCL16 level were analyzed in clinic samples from patients. Exosomes were obtained and verified by gradient centrifugation, transmission electron microscopy, NanoSight analysis and Western blotting. Transwell, immunofluorescence and ELISA were used to detect neutrophil migration and NETs formation.

Results

Our results demonstrated that a large number of neutrophils and NETs, as well as M1 macrophages and exosomal CXCL16, were found in the blood of gallstones patients, especially patients with acute calculous cholecystitis. Exosomal CXCL16 was upregulated in plasma of calculous cholecystitis patients or Lipopolysaccharide induced macrophages, and promoted neutrophil cell migration and NETs formation. Sodium butyrate reduced exosomal CXCL16 secretion through the inhibition of M1 macrophage polarization to suppress neutrophils migration and NETs formation.

Conclusion

Our study suggested that Sodium butyrate may inhibit neutrophils migration and NETs formation to alleviate calculous cholecystitis by reducing exosomal CXCL16 secretion from macrophage and macrophage polarization.

General significance

Our finding may provide a link between exosomes and neutrophils to serve as a potential therapeutic intervention in calculous cholecystitis.

The role of bacteria in gallstone formation

Gallstones are a prevalent biliary system disorder that is particularly common in women. They can lead to various complications, such as biliary colic, infection, cholecystitis, and even gallbladder cancer. However, the etiology of gallstones remains incompletely understood. The significant role of bacteria in gallstone formation has been demonstrated in recent studies. Certain bacteria not only influence bile composition and the gallbladder environment but also actively participate in stone formation by producing enzymes such as β-glucuronidase and mucus. Therefore, this review aimed to analyze the mechanisms involving the types and quantities of bacteria involved in gallstone formation, providing valuable references for understanding the etiology and clinical treatment of gallstones.

Clinical study on the necessity and feasibility of routine MRCP in patients with cholecystolithiasis before LC

BACKGROUND

In the past quite a long time, intraoperative cholangiography(IOC)was necessary during laparoscopic cholecystectomy (LC). Now magnetic resonance cholangiopancreatography (MRCP) is the main method for diagnosing common bile duct stones (CBDS). Whether MRCP can replace IOC as routine examination before LC is still inconclusive. The aim of this study was to analyze the clinical data of patients undergoing LC for cholecystolithiasis, and to explore the necessity and feasibility of preoperative routine MRCP in patients with cholecystolithiasis.

METHODS

According to whether MRCP was performed before operation, 184 patients undergoing LC for cholecystolithiasis in the Department of General Surgery, Beijing Shijitan Hospital, Capital Medical University from January 1, 2017 to December 31, 2018 were divided into non-MRCP group and MRCP group for this retrospective study. The results of preoperative laboratory test, abdominal ultrasound and MRCP, biliary related comorbidities, surgical complications, hospital stay and hospitalization expenses were compared between the two groups.

RESULTS

Among the 184 patients, there were 83 patients in non-MRCP group and 101 patients in MRCP group. In MRCP group, the detection rates of cholecystolithiasis combined with CBDS and common bile duct dilatation by MRCP were higher than those by abdominal ultrasound (P < 0.05). The incidence of postoperative complications in non-MRCP group (8.43%) was significantly higher (P < 0.05) than that in MRCP group (0%). There was no significant difference in hospital stay (P > 0.05), but there was significant difference in hospitalization expenses (P < 0.05) between the two groups. According to the stratification of gallbladder stone patients with CBDS, hospital stay and hospitalization expenses were compared, and there was no significant difference between the two groups (P > 0.05).

CONCLUSIONS

The preoperative MRCP can detect CBDS, cystic duct stones and anatomical variants of biliary tract that cannot be diagnosed by abdominal ultrasound, which is helpful to plan the surgical methods and reduce the surgical complications. From the perspective of health economics, routine MRCP in patients with cholecystolithiasis before LC does not increase hospitalization costs, and is necessary and feasible.

Features of Metabolite Changes in Disease Evolution in Cholecystolithiasis

BACKGROUND

Cholecystolithiasis is defined as a disease caused by complex and changeable factors. Advanced age, female sex, and a hypercaloric diet rich in carbohydrates and poor in fiber, together with obesity and genetic factors, are the main factors that may predispose people to choledocholithiasis. However, serum biomarkers for the rapid diagnosis of choledocholithiasis remain unclear.

AIMS

This study was designed to explore the pathogenesis of cholecystolithiasis and identify the possible metabolic and lipidomic biomarkers for the diagnosis of the disease.

METHODS

Using UHPLC-MS/MS and GC-MS, we detected the serum of 28 cholecystolithiasis patients and 19 controls. Statistical analysis of multiple variables included Principal Component Analysis (PCA). Visualization of differential metabolites was performed using volcano plots. The screened differential metabolites were further analyzed using clustering heatmaps. The quality of the model was assessed using random forests.

RESULTS

In this study, dramatically altered lipid homeostasis was detected in cholecystolithiasis group. In addition, the levels of short-chain fatty acids and amino acids were noticeably changed in patients with cholecystolithiasis. They detected higher levels of FFA.18.1, FFA.20.1, LPC16.0, and LPC20.1, but lower levels of 1-Methyl-L-histidine and 4-Hydroxyproline. In addition, glycine and L-Tyrosine were higher in choledocholithiasis group. Analyses of metabolic serum in affected patients have the potential to develop an integrated metabolite-based biomarker model that can facilitate the early diagnosis and treatment of the disease.

CONCLUSION

Our results highlight the value of integrating lipid, amino acid, and short-chain fatty acid to explore the pathophysiology of cholecystolithiasis disease, and consequently, improve clinical decision-making.

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.

Causal effect of gallstone disease on the risk of coronary heart disease or acute myocardial infarction: a Mendelian randomization study

Gallstone disease (GSD) is thought to be associated with the risk of coronary heart disease (CHD) or acute myocardial infarction (AMI), which may be due to abnormal cholesterol metabolism. We used multiple Mendelian randomization (MR) methods based on publicly available genome-wide association study data to assess whether this association is genetically causal and to search for loci driving causality. Pooled data for GSD were obtained from FinnGen Biobank and Biobank Japan, while CHD and AMI were obtained as pooled data from the CARDIoGRAMplusC4D consortium. In this MR study, we found a significant negative causal effect of genetic susceptibility to GSD on AMI in the Finnish population, but no causal effect was found on CHD. This causal effect was not confounded by reverse causality and the same findings were obtained in the Japanese population. Furthermore, the negative causal effect of GSD on AMI risk may be driven by the rs4245791-regulated ABCG5/8 protein. In conclusion, the results of this MR study support a negative causal effect of GSD on AMI and suggest that rs4245791 is the causal driver locus of this effect, which provides new ideas and evidence for the prevention and etiologic study of AMI in patients with GSD.

The Use of Intraoperative Cholangiography During Cholecystectomy: A Systematic Review

Cholecystectomy is a widespread surgical procedure for gallbladder diseases. Evolving techniques and technologies, such as intraoperative cholangiography (IOC), enhance safety and outcomes by providing real-time biliary system visualization during surgery. This systematic review explored available data on using IOC during cholecystectomy, highlighting its effectiveness, safety, and cost-effectiveness. To perform this systematic review, a thorough literature search was conducted using relevant keywords in electronic databases, such as PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), Cochrane Library, Web of Science, and Google Scholar. We included studies published during the last 10 years exploring the use of IOC during cholecystectomy. The findings showed success rates of up to 90% with a median time of 21.9 minutes without complications. Most (90%) patients with acute gallstone pancreatitis underwent cholecystectomy with IOC, with unclear IOC results in 10.7% and failure in 14.7%. IOC failure factors included age, body mass index (BMI), male sex, concurrent acute cholecystitis, common bile duct (CBD) stone evidence on imaging, CBD diameter of >6 mm, total bilirubin of >4 mg/dL, abnormal liver tests, and gallstone pancreatitis. The detection of choledocholithiasis by IOC prompted trans-cystic duct exploration and endoscopic retrograde cholangiopancreatography (ERCP). Biliary abnormalities and stone identification were observed using IOC, and routine use increased bile duct stone detection while decreasing bile duct injury and readmission rates. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of IOC for common bile duct stone detection were reported at 77%, 98%, 97.2%, 63%, and 99%, respectively. Routine IOC was projected to provide substantial quality-adjusted life years (QALY) and cost-effectiveness gains compared to selective IOC. Regarding safety, IOC was generally associated with reduced complication and open surgery conversion risks, with similar rates of CBD injury and bile leaks. These findings indicate that IOC enhances cholecystectomy outcomes through precision and decreasing complications.

The global prevalence of gallstones in pregnancy: A systematic review and meta-analysis

Background

Gallstone disease is the second most common non-gynecological disease that may require surgical intervention during pregnancy. This study investigates the global prevalence of gallstones in pregnancy through a systematic review and meta-analysis.

Methods

A systematic review and meta-analysis of studies that reported the global prevalence of gallstones in pregnancy was conducted. PubMed, Scopus, Web of Science, Embase, ScienceDirect, and Google Scholar were searched for studies published up to September 2022.

Results

In a review of 31 studies with a sample size of 190,714 people, the I2 heterogeneity test showed high heterogeneity (I2 = 98.8%). Therefore, the random effects method was used to analyze the results. The prevalence of gallstones was reported as 3.6% (95% CI: 1.9-6.7%). The highest prevalence of gallstones by continent was reported in America, at 6.8% (95% CI: 4.2-10.8%). The Egger test showed no evidence of publication bias (p = 0.609).

Conclusion

Based on the results of this study, health policymakers should emphasize to the target community and the medical staff dealing with pregnant women the importance of screening for gallstones during pregnancy.

Analysis of risk factors for complications after laparoscopic cholecystectomy

To analyze the risk factors of complications after laparoscopic cholecystectomy in 478 patients in our hospital.

METHODS

The clinical data of 478 patients who underwent laparoscopic cholecystectomy in our hospital from March 2018 to September 2022 were collected, and the occurrence of postoperative complications and related risk factors were analyzed.

RESULTS

A total of 36 patients (7.53%) had complications, including 9 cases (1.88%) of abdominal hemorrhage, 8 cases (1.67%) of bile duct injury, and 19 cases (3.97%) of biliary fistula. Univariate analysis showed that adhesions of Calot triangle, anatomical variation and gallbladder wall thickness greater than 5 mm were associated with postoperative complications (all P < 0.05). Multivariate analysis showed that: Calot triangle adhesion (OR = 3.041, 95%CI = 1.422-6.507), anatomical variation (OR = 4.368, 95%CI = 1.764-10.813) and gallbladder wall thickening (OR = 2.827, 95%CI = 1.422-6.507). 95%CI = 1.274-6.275) were independent risk factors for complications after laparoscopic cholecystectomy (all P < 0.05).

CONCLUSION

In order to reduce the occurrence of postoperative complications, the risk factors of LC should be well understood and the preoperative preparation should be made.

Acupuncture on GB34 for immediate analgesia and regulating pain-related anxiety for patients with biliary colic: a protocol of randomized controlled trial

BACKGROUND

Biliary colic (BC) is a frequent hepatobiliary disorder encountered in emergency departments. Acupuncture may be effective as an alternative and complementary medicine for BC. Nonetheless, rigorous trials investigating its efficacy are lacking. Therefore, the aim of this study protocol is to determine whether acupuncture provides immediate relief of pain and associated symptoms in BC patients.

METHOD

Eighty-six participants who aged from 18 to 60 years with BC will be recruited in the First People's Hospital of Longquanyi District, Chengdu (West China Longquan Hospital Sichuan University). All participants will be allocated into two treatment groups including acupuncture group and sham acupuncture group using a 1:1 ratio. Each group will only receive a single 30-min needle treatment while waiting for their test results after completing the routine examination for BC. The primary outcome of the study is to assess the change in pain intensity after the 30-min acupuncture treatment. The secondary outcomes of the study include the change in pain intensity at various time points, the degree of gastrointestinal symptoms at different time points, the level of anxiety experienced during pain episodes at different time points, the score of Pain Anxiety Symptoms Scale-20 (PASS-20), the score of Fear of Pain Questionnaire-III (FPQ-III), and the score of Pain Catastrophizing Scale (PCS), among others.

DISCUSSION

The results of this research will provide substantial evidence regarding the efficacy of acupuncture in alleviating symptoms associated with BC.

Utility of the Parkland Grading Scale to determine intraoperative challenges during laparoscopic cholecystectomy: a validation study on 206 patients at an academic medical center in Nepal

BACKGROUND

Most of the scoring systems to predict difficult laparoscopic cholecystectomy are based on pre-operative clinical and radiological findings. Recently the Parkland Grading Scale system was introduced as a simple intra-operative grading scale. This study aims to utilize the Parkland Grading Scale system to assess the intraoperative challenges during laparoscopic cholecystectomy.

METHOD

This was a prospective, cross-sectional study done at Chitwan Medical College and Teaching Hospital, Chitwan, Nepal. All the patients underwent laparoscopic cholecystectomy from April 2020 to March 2021. Based on the initial intra-operative finding, Parkland Grading Scale was noted and at the end of the surgery, the level of difficulty was given by the operating surgeon. All the pre-operative, intra-operative, and post-operative findings were compared with the scale.

RESULTS

Out of 206 patients, there were 176 (85.4%) females, and 30 (14.6%) males. The median age was 41 years (Range 19-75). The median body mass index was 23.67 kg/m2. There were 35(17%) patients with a history of previous surgery. The rate of conversion to open surgery was 5.8%. According to Parkland Grading Scale, 67(32.5%), 75(36.4%), 42(20.4%), 15(7.3%), and 7(3.4%) were graded as grade 1, 2, 3, 4, and 5 respectively. There was a difference in the Parkland grading scale in patients with a history of acute cholecystitis, gallbladder wall thickness, pericholecystic collection, stone size, and body mass index (p < 0.05). The total operative time, level of difficulty in surgery, rate of help needed from colleagues or replacement as the main surgeon, bile spillage, drain placement, gallbladder decompression, and conversion rate all increased with an increase in scale (p < 0.05). There was a significant increase in the development of post-operative fever, and post-operative hospital stay as the scale increased (p < 0.05). The Tukey-Kramer test for all pair-wise comparisons revealed that each grade was significantly different from each other (p < 0.05) on the difficulty of surgery except for grade 4 from 5.

CONCLUSION

Parkland Grading Scale system is a reliable intra-operative grading system to assess the difficulty in laparoscopic cholecystectomy and helps the surgeon to change the strategy of surgery. An increase in scale is associated with an increased difficulty level of the surgery.

[Intraluminal endoscopy for biliary duodenal obstruction]

Cholelithiasis complicated by cholecystoduodenal fistula and small bowel biliary obstruction is an absolute indication for surgical treatment. Modern possibilities of intraluminal endoscopy (electrohydraulic lithotripsy) made it possible to avoid intra-abdominal access (laparotomy, laparoscopy) and postoperative complications. Finally, rapid rehabilitation was noted.

Impacts of the zero mark-up policy on hospitalization expenses of T2DM and cholecystolithiasis inpatients in SC province, western China: an interrupted time series analysis

Background

Since 2009, a series of ambitious health system reforms have been launched in China, including the zero mark-up drug policy (ZMDP); the policy was intended to reduce substantial medicine expenses for patients by abolishing the 15% mark-up on drugs. This study aims to evaluate the impacts of ZMDP on medical expenditures from the perspective of disease burden disparities in western China.

Method

Two typical diseases including Type 2 diabetes mellitus (T2DM) in internal medicine and cholecystolithiasis (CS) in surgery were selected from medical records in a large tertiary level-A hospital in SC Province. The monthly average medical expenses of patients from May 2015 to August 2018 were extracted to construct an interrupted time series (ITS) model to evaluate the impact of policy implementation on the economic burden.

Results

A total of 5,764 cases were enrolled in our study. The medicine expenses for T2DM patients maintained a negative trend both before and after the intervention of ZMDP. It had declined by 74.3 CNY (P < 0.001) per month on average in the pre-policy period and subsequently dropped to 704.4 CNY (P = 0.028) immediately after the policy. The level change of hospitalization expenses was insignificant (P = 0.197), with a reduction of 677.7 CNY after the policy, while the post-policy long-term trend was significantly increased by 97.7 CNY (P = 0.035) per month contrasted with the pre-policy period. In addition, the anesthesia expenses of T2DM patients had a significant increase in the level under the impact of the policy. In comparison, the medicine expenses of CS patients significantly decreased by 1,014.2 CNY (P < 0.001) after the policy, while the total hospitalization expenses had no significant change in level and slope under the influence of ZMDP. Furthermore, the expenses of surgery and anesthesia for CS patients significantly increased by 320.9 CNY and 331.4 CNY immediately after the policy intervention.

Conclusion

Our study indicated that the ZMDP has been an effective intervention to reduce the excessive medicine expenses for both researched medical and surgical diseases, but failed to show any long-term advantage. Moreover, the policy has no significant impact on relieving the overall hospitalization burden for either condition.

Iatrogenic Injury of Biliary Tree-Single-Centre Experience

Cholecystolithiasis is among the most prevalent gastrointestinal disorders requiring surgical intervention, and iatrogenic damage to the bile tree is a severe complication. We aimed to present the frequency of bile duct injuries and how our facility handles these complications. We retrospectively analyzed bile duct injuries in patients undergoing surgery. We concentrated on factors such as sex, age, indications for surgery, type of surgery, primary procedure, bile tree injury, repair, and timing as well as early and late complications. There were 22 cases of bile duct injury in the studied material, primarily affecting women-15 individuals (68.2%). Eleven cases (45.7%) of acute cholecystitis were the primary reason for surgery, and an injury to the common bile duct that extended up to 2 cm from the common hepatic duct was the most common complication (European Association for Endoscopic Surgery grade 2). Roux-en-Y hepaticojejunostomy was the most common repair procedure in 14 cases (63.6%). Eleven patients (50%) experienced early complications following reconstruction surgery, whereas five patients (22.7%) experienced late complications. An annual mortality rate of 22.7% (five patients) was observed. Iatrogenic bile duct injury is a severe complication of surgical treatment for cholecystolithiasis. Reconstruction procedures are characterized by high complication rates and high mortality.

Impacts of COVID-19 on Patients With Common Surgical Emergencies at the King Fahad Specialist Hospital in Buraidah, Saudi Arabia

INTRODUCTION

The COVID-19 pandemic is a global disaster with millions of infections and deaths. Healthcare systems and services were significantly affected, necessitating adjustments. These included postponement of scheduled appointments and elective surgeries. During the pandemic, there was an increase in the number of acute appendicitis, gallstones, and hernia with a significant impact on the signs and symptoms of presenting problems due to prehospital delay.

AIM

This study aims to measure the impacts of COVID-19 on patients with common surgical emergencies in King Fahad Specialist Hospital, Buraidah, Saudi Arabia.

METHODS

This is a single-center retrospective study conducted at King Fahad Specialist Hospital in Buraidah, Saudi Arabia. We reviewed all medical records of patients diagnosed with common surgical emergencies (acute appendicitis, gallstones, and hernia) during a selected time of COVID-19 lockdown and compared it with a similar set period before the crisis as a control sample. All medical records were reviewed to find out the overall number of admissions, frequency of emergency department (ED) visits, duration of illness, picture of clinical presentation, intraoperative findings, course and duration of admission, and final pathology if any.

RESULTS

A total of 322 patients were included in the study. Of these, 119 (37%) patients underwent surgery before COVID-19 while 203 (63%) patients underwent surgery during the pandemic. The diagnosis of acute appendicitis was 63.9% and 47.7%, hernia 27.7% and 34.6%, and gallstone was 8.4% and 17.7% for control and pandemic periods, respectively. The duration varied from 10 hours to two days and four hours to one month, seven hours to one day to eight hours to six months, and two hours to one day to seven hours to one and half a month for acute appendicitis, hernia, and gallstone in control and pandemic period, respectively. The mean length of stay for acute appendicitis was reduced from two days during the control period to one day during the pandemic period, from four to three days for gallstone, and for hernia, it remained three days for both the control and pandemic periods, respectively. Regarding the course of admission for acute appendicitis, the uneventful cases were reduced while an increase in uneventful cases for both hernia and gallstone was observed.

CONCLUSION

During the COVID-19 pandemic, there was a noticeable reduction in hospital visits. We observed an increase in the number of one-time visits and a reduction of three, four, and seven-time visits, which was attributed to the fact that patients have been reported to visit the hospital after a long time from the onset of symptoms with a higher chance of complication and subsequent surgeries. The number of acute appendicitis cases was reduced while the cases of hernia and gallstones increased significantly. The minimum period for the duration of acute illness for appendicitis was reduced in the pandemic period, while the minimum period for both gallstone and hernia was increased as both conditions could require conservative management. The mean length of hospital stay was reduced during the pandemic period, mainly due to the early discharge implemented in COVID-19 protocols to decrease the risk of infection. The severity of symptoms was increased due to the cancellation and delaying of surgeries.

Cholecystectomy for asymptomatic gallstones: Markov decision tree analysis

Gallstones are a common public health problem, especially in developed countries. There are an increasing number of patients who are diagnosed with gallstones due to increasing awareness and liberal use of imaging, with 22.6%-80% of gallstone patients being asymptomatic at the time of diagnosis. Despite being asymptomatic, this group of patients are still at life-long risk of developing symptoms and complications such as acute cholangitis and acute biliary pancreatitis. Hence, while early prophylactic cholecystectomy may have some benefits in selected groups of patients, the current standard practice is to recommend cholecystectomy only after symptoms or complications occur. After reviewing the current evidence about the natural course of asymptomatic gallstones, complications of cholecystectomy, quality of life outcomes, and economic outcomes, we recommend that the option of cholecystectomy should be discussed with all asymptomatic gallstone patients. Disclosure of material information is essential for patients to make an informed choice for prophylactic cholecystectomy. It is for the patient to decide on watchful waiting or prophylactic cholecystectomy, and not for the medical community to make a blanket policy of watchful waiting for asymptomatic gallstone patients. For patients with high-risk profiles, it is clinically justifiable to advocate cholecystectomy to minimize the likelihood of morbidity due to complications.

Cholecystectomy after endoscopic sphincterotomy in elderly: A dilemma

Background/Aim: Although cholecystectomy is recommended by many guidelines after endoscopic retrograde cholangiopancreatography (ERCP) for gallstones, the necessity of cholecystectomy in geriatric patients is a matter of debate. Here we compare the outcomes of new biliary events in cholecystectomized and non-cholecystectomized patients of geriatric age after ERCP for suspected choledocholithiasis. Methods: Non-cholecystectomized patients who underwent ERCP for choledocholithiasis from 2015 to 2017 were included in this retrospective cohort study. Patients with other biliary pathologies, incomplete clearance of common bile duct stones, and those who could not be reached at follow-up were excluded from the study. Biliary events (cholecystitis, cholangitis, pancreatitis, re-ERCP) were evaluated by considering age groups in patients with and without cholecystectomy in their follow-up after sphincterotomy. Results: A total of 284 patients were followed for an average of 69.77 (0.2) months. The cumulative incidence of biliary events in cholecystectomized patients was lower (16% vs. 21.5%; P < 0.001), and cholecystectomized patients had a longer time to the occurrence of events (mean 74.49 [0.27] months vs. 73.50 [0.33] months; P = 0.03). There was no significant difference in the frequency of biliary events between elderly patients with and without cholecystectomy (P = 0.81), and the cumulative incidence of biliary events in the in situ group was significantly lower than that in the geriatric group (17.5% vs 32.6%; P = 0.03) Conclusion: Although cholecystectomy significantly reduces subsequent biliary complications in young patients, it does not provide a statistically significant benefit in geriatric patients. We believe that there may be no need for routine prophylactic cholecystectomy after endoscopic sphincterotomy in geriatric patients.

Global burden of gallbladder and biliary diseases: A systematic analysis for the Global Burden of Disease Study 2019

BACKGROUND AND AIM

Gallbladder and biliary diseases (GBDs) are one of the most prevalent medical issues in the digestive system. This study was designed to describe the characteristics of prevalence, death, and disability-adjusted life years (DALYs) of GBDs during 1990-2019 using data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019.

METHODS

Prevalence, death, and DALYs for GBDs in different locations, years, sex, and age groups were estimated using DisMod-MR 2.1 and a generic Cause of Death Ensemble Modeling approach. Countries and territories were categorized according to socio-demographic index (SDI) quintiles.

RESULTS

The prevalence cases (127 345 732 to 193 493 378), death cases (82 430 to 124 941), and DALYs (4 604 821 to 6 352 738) of GBDs increased from 1990 to 2019. However, the age-standardized rates of indicators decreased over the 30-year period (prevalence, 2851.84 to 2350.78 per 100 000 population; death, 2.40 to 1.65 per 100 000 population; DALYs, 106.76 to 78.25 per 100 000 population). In 2019, the high and middle-high SDI regions had higher age-standardized prevalence rates, the low SDI region had the highest age-standardized death rate, and the middle SDI region had the highest DALYs and age-standardized DALYs rate of GBDs. Being female, older age, and high body mass index were important risk factors for the burden of GBDs.

CONCLUSIONS

Globally, there were improvements in overall health with regard to GBDs over the 30 years. However, the prevention of GBDs should be promoted in middle, middle-high, and high SDI regions, while more medical resources should be provided to improve treatment levels in low SDI region.

The Mitochondrial tRNAPhe 625G>A Mutation in Three Han Chinese Families With Cholecystolithiasis

In this study, we assessed three Chinese families with inherited cholecystolithiasis and conducted the clinical, genetic, and molecular characterization of these subjects. Eight of eighteen matrilineal relatives had a clinical phenotype in these three families. Sequence analysis of complete mitochondrial genomes in these probands identified the homoplasmic tRNA^Phe 625 G > A mutation and distinct sets of mtDNA polymorphisms belonging to haplogroups H2, F4b, and M10a. The 625G > A mutation disturbed the classic G-C base-pairings at a highly conserved position 49 in the T-stem of mitochondrial tRNAs. Molecular dynamics simulation showed that the structure of tRNA^phe with 625 G > A mutation was noticeably remodeled while compared with the isoform of the wild type. The occurrence of tRNA^Phe 625 G > A mutation in these various genetically unrelated subjects strongly indicates that this mutation is involved in the pathogenesis of cholecystolithiasis. This is the first evidence that tRNA mutations are associated with cholecystolithiasis, and it provided more insights into the genetic mechanism of cholecystolithiasis.

Insights From the Analysis of Clinicopathological and Prognostic Factors in Patients With Gallbladder Cancer

Aims

To investigate the clinical efficacy and prognostic factors of primary gallbladder cancer (GBC) treated by radical surgery.

Methods

The clinical and pathological data of 168 patients with primary gallbladder cancer admitted and treated in the Third Affiliated Hospital of Soochow University from January 1st, 2010 to December 31st, 2018 were analyzed retrospectively. Kaplan Meier method was used to draw the survival curve and evaluate the survival rate. Chi-square test was used for univariate analysis and binary logistic regression was used for multivariate analysis.

Results

94 cases showed symptoms of abdominal pain and abdominal distension. 7 cases showed symptoms of fatigue and weight loss. Jaundice occurred in 10 patients. Fever occurred in 6 patients. 51 patients had no symptoms at all. The median survival time of 168 patients was 35.0 (1.0 ~ 142.0) months. The overall 1-, 2- and 3-year cumulative survival rates were 69.6%, 55.4% and 48.8% respectively. The univariate analysis indicated that preoperative bilirubin, tumor size, tumor location, pathological type, degree of differentiation, liver invasion, nerve invasion, vascular invasion, surgical margin, filtration depth and N staging were significant factors influencing prognosis of patients with primary GBC (P<0.05). The results of multivariate analysis demonstrated that degree of differentiation, nerve invasion, filtration depth and N staging were independent risk factors for prognosis of patients with primary GBC (P<0.05).

Conclusion

Patients with risk factors of gallbladder cancer should be more active in early cholecystectomy to avoid the malignant transformation of benign diseases. Degree of differentiation, nerve invasion, filtration depth and N staging were important factors for poor prognosis of patients with primary GBC. For T4 staging patients, preoperative evaluation should be more comprehensive, and patients and surgeons should be more prudent in adopting appropriate clinical treatment. The primary purpose should be prolonging the survival time and improving the quality of life.

The Need for Standardizing Diagnosis, Treatment and Clinical Care of Cholecystitis and Biliary Colic in Gallbladder Disease

Gallstones affect 20% of the Western population and will grow in clinical significance as obesity and metabolic diseases become more prevalent. Gallbladder removal (cholecystectomy) is a common treatment for diseases caused by gallstones, with 1.2 million surgeries in the US each year, each costing USD 10,000. Gallbladder disease has a significant impact on the logistics and economics of healthcare. We discuss the two most common presentations of gallbladder disease (biliary colic and cholecystitis) and their pathophysiology, risk factors, signs and symptoms. We discuss the factors that affect clinical care, including diagnosis, treatment outcomes, surgical risk factors, quality of life and cost-efficacy. We highlight the importance of standardised guidelines and objective scoring systems in improving quality, consistency and compatibility across healthcare providers and in improving patient outcomes, collaborative opportunities and the cost-effectiveness of treatment. Guidelines and scoring only exist in select areas of the care pathway. Opportunities exist elsewhere in the care pathway.

Acute Cholecystitis Presenting With Septic Shock as the First Presentation in an Elderly Patient

Gangrenous cholecystitis (GC), a severe complication of acute cholecystitis, is associated with higher morbidity and mortality rates than uncomplicated cholecystitis. In this report, we present the case of an 81-year-old female with diabetes mellitus and hypertension who presented in the emergency department complaining of severe generalized abdominal pain for 10 days. The pain was associated with nausea and vomiting. She had septic shock, prompting admission, and was eventually diagnosed with perforated GC. Interventional radiology was conducted, and a cholecystostomy tube was placed under radiology guidance with continuous daily irrigation and intravenous antibiotic coverage for four weeks. Subsequently, the patient’s condition improved, and she was finally discharged.

Symptomatic Gallstones in Young Patients Under the Age of 30 Years

Introduction

Gallstones are deposits of digestive fluid that is hardened into small pellets. Gallstones can be symptomatic or asymptomatic. The present study assessed the sociodemographic and clinical characteristics of patients under the age of 30 years old with symptomatic gallstones.

Methodology

A prospective, observational study was conducted at Surgical Unit-3, at Jinnah Postgraduate Medical Centre (JPMC), Pakistan, from July 2020 to July 2021. All patients suspected of having gallstone disease underwent ultrasonic examination. A diagnosis of gallstone disease was made if the gallbladder showed a hyperechoic mass casting a posterior acoustic shadow, with a change of position. All of the patients with gallstone disease were hospitalized. The patients were asked about their age, past history (with special emphasis on last pregnancy and years of oral contraceptive use, if any), socioeconomic status, and other demographic data. The patients were treated with a cholecystectomy, either laparoscopic or open. Postcholecystectomy complications, if any, were recorded.

Results

A total of 210 patients under the age of 30 years were included. The mean age of patients was 25 ± 3 years. The majority of the population were females, i.e., 170 (81%). Upon assessing the risk factors, it was found that 31.84% of the female patients had used oral contraceptives, 32.96% were pregnant at the time of presentation, 20.48% had diabetes mellitus, and 27.14% had a history of gallstones. Furthermore, it was found that about 114 (54.29%) patients were overweight with a body mass index (BMI) of 25-30 kg/m². High triglyceride levels and high cholesterol levels were found in 108 (51.43%) and 115 (54.76%) of the patients, respectively, indicating a link between symptomatic gallstones and younger age.

Conclusion

Our study indicated that young people are prone to symptomatic gallstones. The rate of disease was considerably high among females and in patients with high cholesterol and triglyceride levels and abnormal body mass index. Further exploratory studies are needed to determine the cause of gallstones.

Beyond acute cholecystitis-gallstone-related complications and what the emergency radiologist should know

The purpose of this study is to emphasize the imaging features of complications of gallstones beyond the cystic duct on ultrasound (US), enhanced and nonenhanced computed tomography (CECT and NECT), magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), and endoscopic retrograde cholangiopancreatography (ERCP). This article includes a brief overview of gallstone imaging and emerging trends in the detection of gallstones. This review article will highlight complications of gallstones, including choledocholithiasis, gallstone pancreatitis, acute cholangitis, Mirizzi syndrome, cholecystobiliary and cholecystoenteric fistulas, and gallstone ileus. Imaging findings and limitations of US, CT, MRI, and ERCP will be discussed. The review article will also briefly discuss the management of each disease. The presence of gallstones beyond the level of the cystic duct can lead to a spectrum of diseases, and emergency radiologists play a critical role in disease management by providing a timely diagnosis. Documenting the location of a gallstone within the common bile duct (CBD) in symptomatic cholelithiasis and the presence of acute interstitial edematous pancreatitis and/or ascending cholangitis plays a pivotal role in disease management. Establishing the presence of ectopic gallstones and biliary-enteric fistulae has a significant role in directing patient management.

Quality of life in patients after laparoscopic cholecystectomy due to gallstone disease – evaluation of long-term postoperative results

<b>Introduction:</b> Currently, the standard treatment of gallstone disease is laparoscopic cholecystectomy. Considering its availability, reduction of postoperative pain and shortened stay in the hospital, a constant upward trend in the number of such procedures is observed. However, about one third of patients undergoing such treatment report pain and dyspeptic disorders following the surgery. The assessment of the quality of life of patients undergoing laparoscopic cholecystectomy, based on standardized questionnaires, should be one of the elements allowing for the assessment of the impact of the applied treatment on patients' lives. </br></br> <b>Aim:</b> The aim of this retrospective study is to evaluate the impact of laparoscopic cholecystectomy on the quality of life of patients operated in one center. </br></br> <b>Materials and methods:</b> The study has been carried out retrospectively with the use of a GIQLI questionnaire completed online by the patients 6 months after undergoing laparoscopic cholecystectomy. The study included patients over 18 years of age who have not experienced any complications within the perioperative period and did not require open surgery. The study group has been divided into two subgroups depending on the presence of symptoms of acute gallstone disease in the pre-operative period. </br></br> <b>Results: </b>The study group consisted of 205 patients (53 men, 152 women, aged 19 to 87, with an average of 54.3). The subgroup with an asymptomatic gallstone disease (dyspeptic disorders, without biliary colic) consisted of 47 patients (18 men, 29 women, aged 19–87). Symptomatic gallstone disease occurred in 158 people (35 men, 123 women aged 22 to 81). There have been certain statistically significant differences in the post-operative health condition between the group of patients with symptoms of gallstone disease and the asymptomatic patients. 94.3% of symptomatic patients concluded that their condition has improved and 5.7% that it remained unchanged. Among asymptomatic patients, only 53.2% of patients stated that they felt better post-surgery, 44.7% reported no changes (p < 0.001). There have been no significant differences in the overall QIQLI scores between these subgroups, although symptomatic patients assessed their social functioning better (8.9 ±1.5 vs 8.11 ±2.08, p = 0.004). There have been certain differences between men and women in the assessment of the quality of life in the context of the presence of key symptoms (M: 28.87 ±4.23, F: 26.77 ±5.0, p = 0.007). </br></br> <b> Conclusion:</b> The patients with a symptomatic gallstone disease report they feel better after laparoscopic cholecystectomy as compared to the group of asymptomatic patients. The overall QOL score measured by the GIQLI form does not depend on the presence of symptoms in the preoperative period. Men benefited more from surgery as regards key symptoms.

Diagnostic value of ultrasound combined with MRI in cholecystolithiasis: A protocol for systematic review and meta analysis

BACKGROUND

Early diagnosis of cholecystolithiasis is significant for prevention of further development of situation. Ultrasound is the best choice for the diagnosis of cholecystolithiasis with a sensitivity of >95% and specificity of practically 100%. However, ultrasound is not perfect for it is not so clear sometimes. So, MRI is needed to assist the diagnosing of cholecystolithiasis. Some studies have been conducted to investigate the diagnostic value of ultrasound combined with MRI in cholecystolithiasis, however, the evidence was not enough.

METHODS

We will search the following sources for the identification of trials: The Cochrane Library, PubMed, EMBASE, Chinese Biomedical Literature Database (CBM), Chinese National Knowledge Infrastructure Database (CNKI), Chinese Science and Technique Journals Database (VIP), and the Wanfang Database. The searches were limited to articles published before 1st, April, 2021, and the language were limited to Chinese and English. Statistical analyses will be conducted with Sata 14.0 software and the evaluation of the quality of the included studies will be performed by the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2).

RESULTS

This study will provide a rational synthesis of current evidences for MRI combined with ultrasound for cholecystolithiasis.

CONCLUSION

The conclusion of this study will provide evidence for the diagnostic value of MRI combined with ultrasound for cholecystolithiasis.

ETHICS AND DISSEMINATION

This protocol will not evaluate individual patient information or affect patient rights and therefore does not require ethical approval. Results from this review will be disseminated through peer-reviewed journals and conference reports.

Association of apolipoprotein B XbaI (rs693) polymorphism and gallstone disease risk based on a comprehensive analysis

BACKGROUND

Our aim was to investigate the association between XbaI gene polymorphisms in the apolipoprotein B (APOB) gene and gallstone disease (GD) risk through a comparison of the allele and genotype distribution frequencies at this site using meta-analysis.

METHODS

A literature search was performed using PubMed and Wanfang through Jun 1, 2020. Odds ratios (ORs) and 95 % confidence intervals (CIs) were used to assess the strength of associations.

RESULTS

After a comprehensive search, 14 different articles that met the inclusion criteria were selected, with 1583 cases and 1794 controls. Individuals carrying the A-allele or AA genotype of the rs693 polymorphism were determined to possibly have an increased risk of GD. For example, there was a significant relationship between the rs693 polymorphism and increased GD risk in the whole group (OR: 1.40, 95 % CI: 1.05-1.87 in the allelic contrast model), the Asian population (OR: 1.58, 95 % CI: 1.48-2.84 in the heterozygote model), and the hospital-based source of the control (OR: 1.79, 95 % CI: 1.13-2.84 in the dominant model).

CONCLUSIONS

This study suggests that the APOB rs693 polymorphism is potentially associated with GD susceptibility, which might offer a detection marker for use in future large scale clinic research.

Gallbladder stone incidence and prevalence in Germany: a population-based study

BACKGROUND

 We aimed to determine the prevalence and incidence of gallbladder stones in a random population-based collective in Germany.

METHODS

 We determined the prevalence and incidence rates of gallbladder stones in a random population sample of 1909 individuals from the Echinococcus-multilocularis in Leutkirch (EMIL) study in 2002 and 380 individuals in a follow-up analysis in the year 2013. The sonographic analysis was performed with a Philipps HDI 5000 (2002) and IU 22 (2013) (Netherlands) transducer 1-5 MHz. Statistical analysis was performed using SAS Version 9.4.

RESULTS

 The prevalence of gallbladder stones was 3.8 % (69/1909) in 2002 and 10.8 % (41/380) in 2013. In 2013, the gallbladder stone prevalence was 15.1 % (26/172) in women, compared to 7.2 % (15/208) in men. No gallbladder stones were found in participants in the 18-30 or 31-40 age groups. The average annual incidence was 1.03 % in the 41-50 age group, 0.79 % in the 51-65 age group, and 0.63 % in the > 65 age group. The annual incidence was higher among women (1.04 %) than men (0.53 %). The age-associated annual incidence rates for women and men were 1.93 % and 0.5 % in the 41-50 age group, 0.8 % and 0.78 % in the 51-65 age group, and 1.06 % and 0.30 % in the > 65 age group.

CONCLUSION

 For the investigated German collective from 2002 to 2013, the average annual incidence of gallbladder stones was 0.75 %, with a higher incidence rate among women. These results are consistent with data from comparable international studies.

[Upper abdominal pain: a frequent and multifaceted leading symptom in primary care internal medicine]

Upper gastrointestinal symptoms are among the most common reasons for medical consultation and represent a challenge for general practitioners in the outpatient care setting. History taking, symptom evaluation and physical examination are the crucial steps toward establishing an initial working diagnosis. The subsequent abdominal ultrasound and laboratory analyses are essential tools for the differential diagnosis.
