Current considerations for the surgical management of gallbladder adenomas

Gallbladder adenomas are rare lesions(0.5%)associated with potential malignant transformation,particularly with gallbladder adenomas that are≥1 cm in size.Early detection and management are crucial for preventing lethal carcinoma de-velopment.These polyps can often be distinguished from the more often nonneo-plastic cholesterol pseudopolyps(5%-10%),which are benign.Ultrasonography is the first-line tool for initial diagnosis and follow-up when indicated.The question is whether cholecystectomy is always necessary for all adenomas.The manage-ment of gallbladder adenomas is determined according to the size of the tumor,the growth rate of the tumor,the patient’s symptoms and whether risk factors for malignancy are present.Adenomas≥1 cm in size,an age>50 years and a familial history of gallbladder carcinoma are indications for immediate laparoscopic chole-cystectomy.Otherwise,ultrasound follow-up is indicated.For adenomas 6-9 mm in size,the absence of≥2 mm growth at 6 months,one year,and two years,as well as an adenoma sized<5 mm without existing risk factors indicates that no further surveillance is required.However,it would be preferable to individualize the management in doubtful cases.Novel interventional modalities for preserving the gallbladder need further evaluation,especially to determine the long-term outcomes.

Occult pancreaticobiliary reflux is a pathogenic factor of some benign biliary diseases and gallbladder cancer

Background:Pancreaticobiliary maljunction(PBM)is a well-known high-risk factor for biliary malignant tumors because of constant pancreaticobiliary reflux(PBR).However,the impact of occult pancreaticobiliary reflux(OPR),which is characterized by high bile amylase levels in individuals with anatomically normal pancreaticobiliary junction,on biliary diseases remains unclear.The aim of this study was to assess the correlation between OPR and biliary diseases.Methods:We enrolled 94 consecutive patients with normal pancreaticobiliary junction and primary biliary diseases confirmed by magnetic resonance cholangiopancreatography.We prospectively collected patients’bile samples and measured bile amylase levels.We investigated the incidence of OPR and the difference in bile amylase levels among these patients and assessed the correlation between high bile amylase levels(HBAL)and benign or malignant biliary diseases,as well as the OPR risk factors.Results:The incidence of OPR was 36.6%in patients with benign biliary diseases,26.7%in those with cholangiocarcinoma and 62.5%in those with gallbladder cancer.The median bile amylase level tended to be higher in patients with gallbladder cancer than in those with benign biliary diseases,but there was no significant difference(165.5 IU/L vs.23.0 IU/L,P=0.212).The prevalence of an HBAL with bile amylase levels of 1000-7500 IU/L was similar in patients with gallbladder cancer and benign biliary diseases.However,the incidence of HBAL with bile amylase levels greater than 7500 IU/L was significantly higher in patients with gallbladder cancer than in those with benign biliary diseases(37.5%vs.4.2%,P=0.012).Multivariate logistic regression analysis revealed that choledocholithiasis was an independent risk factor for OPR.Conclusions:OPR can occur in benign and malignant biliary diseases,and it may be a pathogenic factor for some benign biliary diseases and a high-risk factor for gallbladder cancer.There is a correlation between choledocholithiasis and OPR.

Global, regional, and national burden of gallbladder and biliary diseases from 1990 to 2019

BACKGROUND Gallbladder and biliary diseases(GABDs)are a major public health issue.AIM To analysis the cause-specific incidence,prevalence,and years lived with disability(YLDs)and its temporal trends of GABDs at the global,regional,and national level.Data on GABD were available from the Global Burden of Disease study 2019.METHODS The estimated annual percentage change(EAPC)was used to quantify temporal trend in GABD age-standardized incidence rates(ASIRs),age-standardized prevalence rate(ASPR),and age-standardized YLD rate(ASYR)by region,sex.We analyzed the relationship between the GABD burden and country development level using the human development index(HDI).RESULTS In 2019,the incident cases of GABD were 52003772,with an ASIR of 63432/100000 population.Globally,the number of incident cases and ASIR of GABD increased 97%and 58.9%between 1990 and 2019.Although,the ASPR and ASYR decreased from 1990 to 2019,the number of prevalent and YLDs cases increased.The highest ASIR was observed in Italy,and the highest ASPR and ASYR was observed in United Kingdom.The highest burden of GABD was found in low-SDI region,and the burden in female was significantly higher than males.A generally negative correlation(ρ=-0.24,P<0.05)of GABD with the EAPC and human development index(HDI)(in 2021)were observed for ASIR.What’s more,no correlation in ASPR(ρ=-0.06,P=0.39)and ASYR(ρ=-0.07,P=0.36)of GABD with the EAPC and HDI(in 2021)were observed,respectively.CONCLUSION GABD remain a major global public health challenge;however,the burden of GABD varies geographically.Globally,the number of incident cases and ASIR of GABD increased between 1990 and 2019.The results of our study provide insight into the global disease burden of GABD and may assist policymakers in formulating effective policies to mitigate modifiable risk factors.

New trends in diagnosis and management of gallbladder carcinoma

Gallbladder(GB)carcinoma,although relatively rare,is the most common biliary tree cholangiocarcinoma with aggressiveness and poor prognosis.It is closely associated with cholelithiasis and long-standing large(>3 cm)gallstones in up to 90%of cases.The other main predisposing factors for GB carcinoma include molecular factors such as mutated genes,GB wall calcification(porcelain)or mainly mucosal microcalcifications,and GB polyps≥1 cm in size.Diagnosis is made by ultrasound,computed tomography(CT),and,more precisely,magnetic resonance imaging(MRI).Preoperative staging is of great importance in decisionmaking regarding therapeutic management.Preoperative staging is based on MRI findings,the leading technique for liver metastasis imaging,enhanced three-phase CT angiography,or magnetic resonance angiography for major vessel assessment.It is also necessary to use positron emission tomography(PET)-CT or ^(18)F-FDG PET-MRI to more accurately detect metastases and any other occult deposits with active metabolic uptake.Staging laparoscopy may detect dissemination not otherwise found in 20%-28.6%of cases.Multimodality treatment is needed,including surgical resection,targeted therapy by biological agents according to molecular testing gene mapping,chemotherapy,radiation therapy,and immunotherapy.It is of great importance to understand the updated guidelines and current treatment options.The extent of surgical intervention depends on the disease stage,ranging from simple cholecystectomy(T1a)to extended resections and including extended cholecystectomy(T1b),with wide lymph node resection in every case or IV-V segmentectomy(T2),hepatic trisegmentectomy or major hepatectomy accompanied by hepaticojejunostomy Roux-Y,and adjacent organ resection if necessary(T3).Laparoscopic or robotic surgery shows fewer postoperative complications and equivalent oncological outcomes when compared to open surgery,but much attention must be paid to avoiding injuries.In addition to surgery,novel targeted treatment along with immunotherapy and recent improvements in radiotherapy and chemotherapy(neoadjuvant-adjuvant capecitabine,cisplatin,gemcitabine)have yielded promising results even in inoperable cases calling for palliation(T4).Thus,individualized treatment must be applied.

Gallbladder carcinosarcoma with a poor prognosis: A case report

BACKGROUND Carcinosarcoma of the gallbladder is a rare malignant tumor with a very poor prognosis.To date,only approximately 100 patients have been reported in the English literature.The prognosis of this tumor type is poor,the preoperative diagnosis is difficult,and there is a possibility of a misdiagnosis.We present an unsuccessful case of carcinosarcoma of the gallbladder with a preoperative misdiagnosis and rapid early postoperative recurrence.Therefore,we have a deeper understanding of the poor prognosis of gallbladder carcinosarcoma(GBC)patients.CASE SUMMARY The patient is a 65-year-old male.He was admitted to the hospital because of right upper abdomen distending pain and discomfort for half a month.Abdominal magnetic resonance imaging revealed a polycystic mass in the right lobe of the liver and the fossa of the gallbladder.After admission,the patient was diagnosed with a liver abscess,which was treated by abscess puncture drainage.Obviously,this treatment was unsuccessful.Hepatectomy and cholecystectomy were performed one month after the puncture.Postoperative pathologic examination revealed carcinosarcoma of the gallbladder,and the resected specimen contained two tumor components.One month after surgery,the patient's tumor recurred in situ and started to compress the duodenum,resulting in duodenal obstruction and bleeding.The treatment was not effective.The patient died of gastrointestinal hemorrhage and hypovolemic shock.CONCLUSION Carcinosarcoma of the gallbladder is a rare malignant tumor that is easily misdiagnosed preoperatively and has a poor prognosis.

Effects of cytoreductive surgery combined with hyperthermic perfusion chemotherapy on prognosis of patients with advanced gallbladder cancer

BACKGROUND Gallbladder cancer(GC)is a common malignant tumor and one of the leading causes of cancer-related death worldwide.It is typically highly invasive,difficult to detect in the early stages,and has poor treatment outcomes,resulting in high mortality rates.The available treatment options for GC are relatively limited.One emerging treatment modality is hyperthermic intraperitoneal chemotherapy(HIPEC).HIPEC involves delivering heated chemotherapy directly into the abdominal cavity.It combines the strategies of surgical tumor resection and localized chemotherapy administration under hyperthermic conditions,aiming to enhance the concentration and effectiveness of drugs within the local tumor site while minimizing systemic toxicity.AIM To determine the effects of cytoreductive surgery(CRS)combined with HIPEC on the short-term prognosis of patients with advanced GC.METHODS Data from 80 patients treated at the Punan Branch of Renji Hospital,Shanghai Jiao Tong University School of Medicine between January 2018 and January 2020 were retrospectively analyzed.The control group comprised 44 patients treated with CRS,and the research group comprised 36 patients treated with CRS combined RESULTS The baseline data of the research and control groups were similar(P>0.05).Six days after surgery,the alanine aminotransferase,aspartate aminotransferase,total bilirubin,and direct bilirubin levels significantly decreased compared to the preoperative levels in both groups(P<0.05).However,the values did not differ between the two groups six days postoperatively(P>0.05).Similarly,the postoperative creatinine and blood urea nitrogen levels were significantly lower than the preoperative levels in both groups(P<0.05),but they did not differ between the groups six days postoperatively(P>0.05).Furthermore,the research group had fewer postoperative adverse reactions than the control group(P=0.027).Finally,a multivariate Cox analysis identified the tumor stage,distant metastasis,and the treatment plan as independent factors affecting prognosis(P<0.05).The three-year survival rate in the study group was higher than that in the control group(P=0.002).CONCLUSION CRS combined with HIPEC lowers the incidence of adverse reactions and improves survival in patients with advanced GC.

Expression profile of cholecystokinin type-A receptor in gallbladder cancer and gallstone disease

BACKGROUND:Regulatory peptide receptors have attracted the interest of oncologists as a new promising approach for cancer pathology,imaging and therapy.Although cholecystokinin (CCK) is a potent modulator of gallbladder contractility and plays a potential role in pancreatic carcinogenesis through CCK type-A receptor (CCKAR),its role in gallbladder cancer (GBC) is still unknown and immunohistochemical detection of CCKAR in the gallbladder has not yet been reported.This novel case-control study aimed to investigate the expression profile of CCKAR in GBC and gallstone disease (GSD).METHODS:This study included 162 samples of gallbladder:94 from GBC and 68 from GSD.Expression of CCKAR was analyzed by immunohistochemistry and immunoblotting.The results were statistically correlated with disease history including age,sex,presence of gallstone,stage and differentiation.RESULTS:CCKAR was positive in 30/68 (44.1%) of GSD and 72/94 (76.6%) of GBC samples.Fifty-one of the 72 (70.8%) CCKAR-positive GBC samples showed over-expression.Interestingly,consistent results also appeared in the immunoblotting study.CONCLUSIONS:CCKAR expression was significantly increased in GBC compared to GSD.Moreover,CCKAR expression was associated with the degree of tumor differentiation,i.e.,less expression in poorly-differentiated tumors.Thus,it has future prognostic and therapeutic implications in the management of GBC.

Gallbladder function and dynamics of bile flow in asymptomatic gallstone disease

AIM： To investigate the effects of gallbladder stones on motor functions of the gallbladder and the dynamics of bile flow in asymptomatic gallstone disease. METHODS： Quantitative hepatobiliary scintigraphy was performed to detect the parameters of gallbladder motor function [gallbladder ejection fraction （GBEF）, gallbladder visualization time （GBVT）, gallbladder time to peak activity （GBTmax）, gallbladder half emptying time （GBT1/2）, and transit time of bile to duodenum （TTBD）] in 24 patients with asymptomatic cholelithiasis who were diagnosed incidentally during routine abdominal ultrasonographic examination and 20 healthy subjects with normal gallbladder. RESULTS： Even though there was no significant difference in the clinical and laboratory parameters between the patient and control groups, all parameters of gallbladder function except TTBD were found to differ significantly between the two groups. GBEF in the patient group was decreased （P = 0.000） and GBVT, GBT GBT1/2 in the patient group were longer （P = 0.000, P = 0.015, P = 0.001, respectively）.there were not any clinical and laboratory findings, gallbladder filling and emptying could be impaired in patients with gallstone disease.

Gallbladder carcinoma in a pregnant patient with Crohn's disease complicated with gallbladder involvement

Primary gallbladder (GB) carcinoma and Crohn's disease (CD) of the GB are individually rare. We present a case of a pregnant woman with CD found to have GB involvement and primary GB carcinoma. A 34-year-old female at 6 wk gestation with a 21 year history of CD of uncertain extent presented with 3 mo of diarrhea, urgency and abdominal pain. During work-up, she was found to have elevated transaminases and an abnormal alkaline phosphatase. Imaging revealed two gallbladder polyps both greater than 1 cm in size. Resection and histological evaluation was consistent with Crohn's involvement of the GB, poorly differentiated adenocarcinoma of the GB with invasion through the muscularis propria and matted lymph nodes in the porta hepatis positive for metastatic carcinoma (stage pT2N1). Six cases of CD involving the GB, two cases of primary GB carcinoma in CD, and ten cases of cholangiocarcinoma in pregnancy have been published.This is the only case that describes all three factors. Common features in CD of the GB include acute cholecystitis, ileal involvement, and presence independent of active intestinal disease. Common features in CD patients with GB malignancy include younger age of detection, a long history of CD, extensive colonic and ileal involvement of disease, the absence of cholelithiasis, and pre-existing gallbladder disease (primary sclerosing cholangitis and gallbladder polyps). Pregnancy is specific to this case. The role of CD in the development of GB malignancy is not well understood nor is the contribution of pregnancy to the spread of disease. Chronic inflammation and immunosuppression compounded by hormonal influence is implicated.

Objective:To Discuss the correlation between Hypersensitivity C-reactive Protein(Hs-CRP),Total Cholesterol(TC),Triglyceride(TG),negative emotion scale and TCM syndrome scores in“Double Heart Disease”patients with Qi stagnation blood stasis and heart gallbladder heat stagnation.Method:Fifty-two patients in Western Medicine Diagnosis of Double Heart Disease,in TCM syndrome identified as Qi stagnation blood stasis Heart gallbladder heat stagnation syndrome,detects it Hs-CRP,TC,TG levels by ELISA,use TCM Syndromes Scale to evaluate TCM Syndrome,use the Pittsburgh Sleep Quality Index(PSQI)and Self-rating symptom scale(SCL-90)to assess anxiety and sleep levels,analyze the correlation between TCM syndrome scores and Hs-CRP,TC,TG level,PSQI index,SCL-90 index.Result:There was a significant positive correlation between Hs-CRP,TG level and TCM Syndrome scores(P<0.05);TC level was postively correlated with TCM Syndrome scores,but there was no statistical significance(P>0.05);There was a significant positive correlation between PSQI index,SCL-90 index and TCM Syndrome scores(P<0.05).Conclusion:In“Double Heart Disease”patients with Qi stagnation blood stasis and heart gallbladder heat stagnation,there have characteristic syndrome changes in terms of inflammatory factor level,blood lipid level and negative emotion score;Which the above indexes can reflect the severity of TCM syndromes to a certain extent and provide the basis for the effective intervention treatment of TCM.

Gallbladder motor function, plasma cholecystokinin and cholecystokinin receptor of gallbladder in cholesterol stone patients

AIM: To study the interactive relationship of gallbladder motor function, plasma cholecystokinin (CCK) and cholecystokinin A receptor (CCK-R) of gallbladder in patients with cholesterol stone disease.METHODS: Gallbladder motility was studied by ultrasonography in 33 patients with gallbladder stone and 10 health subjects as controls. Plasma CCK concentration was measured by radioimmunoassay in fasting status (CCK-f) and in 30 min after lipid test meal (CCK-30).Radioligand method was employed to analyze the amount and activity of CCK-R from 33 gallstone patients having cholecystectomy and 8 persons without gallstone died of severe trauma as controls.RESULTS: The percentage of cholesterol in the gallstone composition was more than 70%. The cholesterol stone type was indicated for the patients with gallbladder stone in this study. Based on the criterion of gallbladder residual fraction of the control group, 33 gallstone patients were divided into two subgroups, contractor group (14 cases)and non-contractor group (19 cases), The concentration of CCK-30 was significantly higher in non-contractor group than that in both contractor group and control group (55.86±3.86 pmol/l vs 37.85±0.88 pmol/l and 37.95±0.74 pmol/L, P＜0.01), but there was no difference between contractor group and control group. Meanwhile no significant difference of the concentration of CCK-f could be observed among three groups. The amount of CCK-R was lower in non-contractor group than those in both control group and contractor group (10.27±0.94 fmol/mg vs24.59±2.39 fmol/mg and 22.66±0.55 fmol/mg, P＜0.01).The activity of CCK-R shown as KD in non-contractor group decreased compared to that in control group and contractor group. Only was the activity of CCK-R lower in contractor group than that in control group. The ejection fraction correlated closely with the amount of CCK-R (r = 0.9683,P＜0.01), and the concentration of CCK-30 correlated negatively with the amount of CCK-R closely (r = -0.9627,P＜0.01).CONCLUSION: The distinctive interactive relationship of gallbladder emptying, plasma CCK and CCK-R in gallbladder from this study suggested that the defect of CCK-R may be a key point leading to the impairment of gallbladder motor function and the pathogenesis of cholesterol gallstoneformation may differ in two subgroups of gallstone patient,gallbladder non-contractor group or contractor group.

Imaging-based algorithmic approach to gallbladder wall thickening

Gallbladder(GB) wall thickening is a frequent finding caused by a spectrum of conditions. It is observed in many extracholecystic as well as intrinsic GB conditions. GB wall thickening can either be diffuse or focal. Diffuse wall thickening is a secondary occurrence in both extrinsic and intrinsic pathologies of GB, whereas, focal wall thickening is mostly associated with intrinsic GB pathologies. In the absence of specific clinical features, accurate etiological diagnosis can be challenging. The survival rate in GB carcinoma(GBC) can be improved if it is diagnosed at an early stage, especially when the tumor is confined to the wall. The pattern of wall thickening in GBC is often confused with benign diseases, especially chronic cholecystitis, xanthogranulomatous cholecystitis, and adenomyomatosis. Early recognition and differentiation of these conditions can improve the prognosis. In this minireview, the authors describe the patterns of abnormalities on various imaging modalities(conventional as well as advanced) for the diagnosis of GB wall thickening. This paper also illustrates an algorithmic approach for the etiological diagnosis of GB wall thickening and suggests a formatted reporting for GB wall abnormalities.

Gallbladder cancer:Historical treatment and new management options

Gallbladder cancer is a rare,aggressive malignancy that has a poor overall prognosis.Effective treatment consists of early detection and surgical treatment.With the wide spread treatment of gallbladder disease with minimally invasive techniques,the rate of incidental gallbladder cancer has seen an equitable rise along with stage migration towards earlier disease.Although the treatment remains mostly surgical,newer modalities such as regional therapy as well as directed therapy based on molecular medicine has led to improved outcomes in patients with advanced disease.We aim to summarize the management of gallbladder cancer along with the newer developments in this formidable disease process.

Expression of pituitary adenylate cyclase-activating polypeptide 1 and 2 receptor mRNA in gallbladder tissue of patients with gallstone or gallbladder polyps

AIM： To detect the expression of pituitary adenylate cyclase-activating polypeptide receptor i （VPCAPrR） and VPCAP2-R mRNA in gallbladder tissues of patients with gallstone or gallbladder polyps. METHODS： The expression of VPCAP1-R and VPCAP2-R mRNA in gallbladder tissues was detected in 25 patients with gallstone, 8 patients with gallbladder polyps and 7 donors of liver transplantation by reverse transcription polymerase chain reaction （RT-PCR）. RESULTS： The VPCAP2-R mRNA expression level in the control group （1.09±0.58） was lower than that in the gallbladder polyp group （1.64±0.56） and the gallstone group （1.55±0.45） （P〈0.05） while the VPCAP1-R mRNA expression level in the control group （1.15 ±0.23） was not apparently different from that in the gallbladder polyp group （1.28±0.56） and the gallstone group （1.27± 0.38）. CONCLUSION： The abnormal expression of VPCAP2-R mRNA in gallbladder tissue may play a role in the formation of gallbladder stone and gallbladder polyps.

Diagnosis of Tumor-Like Polypoid Lesions of Gallbladder by Serum Proteomic Fingerprint

Objective： To search the specific serum proteins in tumor-like polypoid lesions of the gallbladder（PLG） patients. Methods： Surface enhanced laser desorption/ionization time of flight mass spectrometry （SELDI-TOF-MS） technique and WCX Magnetic Beads were used to detect the serum proteomic fingerprint of 23 patients with tumor-like PLG, 21 patients with non tumor-like PLG and 26 normal persons. Biomarker Wizard and Biomarker Patterns Software were used in combination to analyze the data. Results： In the preliminary screening, 22 representative specific proteins for tumor-like PLG were found. Seven specific proteins showed increased expression and 15 specific proteins showed decreased expression in the tumor-like PLG patients. Three specific proteins are selected for the diagnosis of the tumor-like PLG.. Conclusion： SELDI-TOF-MS technique can be used to select specific proteins for tumor-like PLG patients, which may be useful for the diagnosis of the tumor-like PLG and the differential diagnosis with the non tumor-like PLG.

Impact of nonalcoholic fatty liver disease on the risk of gallbladder polyps in lean and non-obese individuals:A cohort study

Background:The association between non-obese or lean nonalcoholic fatty liver disease(NAFLD)and gallbladder polyps(GBPs)has not yet been evaluated.We aimed to determine whether NAFLD is an independent risk factor for the development of GBPs,even in non-obese and lean individuals.Methods:We analyzed a cohort of 331208 asymptomatic adults who underwent abdominal ultrasonography(US).The risk of GBP development was evaluated according to the obesity and NAFLD status.Results:The overall prevalence of NAFLD and GBPs≥5 mm was 28.5%and 2.9%,respectively.The prevalence of NAFLD among 160276 lean,77676 overweight and 93256 obese participants was 8.2%,31.2%,and 61.1%,respectively.Individuals with NAFLD had a significantly higher incidence of GBPs with a size of≥5 mm[adjusted odds ratio(OR)=1.18;95%confidence interval(CI):1.11–1.25].A higher body mass index and its categories were also significantly associated with an increased risk of GBPs≥5 mm.Moreover,risk of GBPs≥5 mm was significantly increased even in NAFLD individuals who are not obese(lean:adjusted OR=1.36,95%CI:1.19-1.54;overweight:adjusted OR=1.14,95%CI:1.03–1.26,respectively).Conclusions:Non-obese/lean NAFLD is an independent risk factor for GBP development,suggesting that NAFLD may play an important role in the pathogenesis of GBPs regardless of the obesity status.Therefore,a more thorough evaluation for GBPs may be necessary when hepatic steatosis is detected on abdominal US,even in non-obese or lean individuals.
