Machine learning-based diagnostic model for preoperative differentiation between xanthogranulomatous cholecystitis and gallbladder carcinoma: a multicenter retrospective cohort study. Front Oncol 2024; 14:1355927. [PMID: 38476361 PMCID: PMC10927717 DOI: 10.3389/fonc.2024.1355927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2023] [Accepted: 02/05/2024] [Indexed: 03/14/2024] Open
Abstract
Background Xanthogranulomatous cholecystitis (XGC) and gallbladder carcinoma (GBC) share similar imaging and serological profiles, posing significant challenges in accurate preoperative diagnosis. This study aimed to identify reliable indicators and develop a predictive model to differentiate between XGC and GBC. Methods This retrospective study involved 436 patients from Zhejiang Provincial People's Hospital and The Affiliated Lihuili Hospital of Ningbo University. Comprehensive preoperative imaging, including ultrasound, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and blood tests, were analyzed. Machine learning (Random Forest method) was employed for variable selection, and a multivariate logistic regression analysis was used to construct a nomogram for predicting GBC. Statistical analyses were performed using SPSS and RStudio software. Results The study identified gender, Murphy's sign, absolute neutrophil count, glutamyl transpeptidase level, carcinoembryonic antigen level, and comprehensive imaging diagnosis as potential risk factors for GBC. A nomogram incorporating these factors demonstrated high predictive accuracy for GBC, outperforming individual or combined traditional diagnostic methods. External validation of the nomogram showed consistent results. Conclusion The study successfully developed a predictive nomogram for distinguishing GBC from XGC with high accuracy. This model, integrating multiple clinical and imaging indicators, offers a valuable tool for clinicians in making informed diagnostic decisions. The findings advocate for the use of comprehensive preoperative evaluations combined with advanced analytical tools to improve diagnostic accuracy in complex medical conditions.

The utility of systemic immune inflammatory index in discriminating between gallbladder cancer and xanthogranulomatous cholecystitis: A single-tertiary center experience. Medicine (Baltimore) 2023; 102:e35805. [PMID: 37904388 PMCID: PMC10615518 DOI: 10.1097/md.0000000000035805] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Accepted: 10/04/2023] [Indexed: 11/01/2023] Open
Abstract
Xanthogranulomatous cholecystitis (XGC) and gallbladder carcinoma (GBC) are rare diseases with several similarities. This study aimed to evaluate the utility of the systemic immune inflammatory index (SII), a novel index that more accurately depicts inflammatory and immunological balance, in distinguishing between XGC and GBC. This retrospective study included 33 XGC, 22 GBC patients diagnosed according to histopathological findings and 33 age-sex-matched healthy controls at Hacettepe University Faculty of Medicine, General Surgery Department. The demographic, clinical and laboratory findings were recorded. Neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, monocyte to lymphocyte ratio and SII were calculated from preoperative complete blood count parameters. The receiver operating characteristic curve was performed to evaluate the utility of SII in differentiating GBC and XGC. A P value < .05 was accepted as statistically significant. The preoperative neutrophil to lymphocyte ratio, monocyte to lymphocyte ratio, platelet to lymphocyte ratio and SII were significantly higher in patients with GBC compared to XGC patients and healthy controls (P < .001, P = .001, P = .001, P < .001, respectively). When receiver operating characteristic analysis was made, the optimal cutoff value of SII was 640 for differential diagnosis of XGC and GBC preoperatively with a sensitivity of 77.3% and a specificity of 66.7%, among which the positive likelihood ratio was 2.32, and Youden index was 0.44 (P = .006). The positive predictive value was 60.7%, the negative predictive value was 81.5%, and the diagnostic accuracy was 79.9%. SII may be a valuable, practical, and affordable method to differentiate between XGC and GBC, in addition to clinical and radiological signs, prior to surgery. When supported by prospective trials with a larger study population, distinguishing GBC from XGC using SII preoperatively may lead to a change in the management practice of GBC.

Abstract
Xanthogranulomatous cholecystitis (XGC) is a rare form of chronic gallbladder inflammation that most commonly presents as acute cholecystitis and is often mistaken for carcinoma of the gallbladder. This case details the hospital course and follow-up of a 77-year-old male who developed suspected acute acalculous cholecystitis (AAC) resulting in severe sepsis after elective left total knee arthroplasty (TKA). Histopathological findings after elective cholecystectomy later revealed XGC as the underlying etiology.

Abstract
Xanthogranulomatous inflammation (XGI) is a rare, benign condition that can affect several organs, including the gallbladder, kidney, skin, gastrointestinal tract, lymph nodes, and soft tissues. It is often misdiagnosed as a malignancy. In this report, we present the case of a 79-year-old male who presented with persistent jaundice for 11 months. Computed tomography and magnetic resonance imaging revealed pancreatic head enlargement, gallbladder thickening, and common bile duct thickening, leading to a preoperative diagnosis of malignant neoplasm of the pancreatic head. During surgery, dense adhesions were found around the portal vein, suggestive of mass invasion. To relieve obstruction, choledochojejunostomy was performed. Postoperative pathological examination revealed xanthogranulomatous cholecystitis (XGCc), xanthogranulomatous cholangitis (XGCg), and xanthogranulomatous pancreatitis (XGP). XGI affecting the bile ducts and pancreas is extremely rare, and there are no reported cases of simultaneous involvement of the gallbladder, bile duct, and pancreas by XGI. This study provides valuable insight into the differential diagnosis of XGI by presenting the imaging features of XGI patients.

Abstract
Gallbladder disease is a very common condition that encompasses a heterogeneous group of diseases with a wide range of severity and clinical manifestations. Gallbladder disorders include biliary colic, acute cholecystitis, chronic cholecystitis, choledocholithiasis, Mirizzi syndrome, and gallstone ileus. We report the case of a 70-year-old man who presented to the emergency department complaining of worsening abdominal pain, located in the right upper quadrant and radiating to the right shoulder. It was aggravated by food intake and relieved with the use of antacid medications. The medical history of the patient was significant for stable angina, hypertension, diabetes mellitus, hyperlipidemia, and sickle cell trait. Examination of the abdomen revealed generalized tenderness with guarding. Abdominal computed tomography scan demonstrated the presence of significant diffuse thickening of the gallbladder wall with poor contrast enhancement. Complete resection of the gallbladder was performed because of suspected gallbladder carcinoma. Histopathological examination revealed xanthogranulomatous cholecystitis, which is a rare form of chronic cholecystitis. The differentiation between gallbladder carcinoma and xanthogranulomatous cholecystitis may not be easy and histopathological examination is the most accurate way to make the diagnosis.

Abstract
Background Xanthogranulomatous cholecystitis (XGC) is an extremely rare entity. Due to XGC’s clinical and radiological resemblance to gallbladder carcinoma (GBC), intraoperative frozen section during cholecystectomy is often performed to exclude the diagnosis of GBC. Our study is aiming to find a noninvasive indicator of XGC. To our knowledge, this is the largest XGC cohort ever studied. Methods This study retrospectively collected clinical characteristics, serological tests, and imaging features of 150 GBC patients and 90 XGC patients. The diagnosis of these 150 GBC patients and 90 XGC patients was based on intraoperative frozen section histopathology. T‐test was utilized to compare differences between XGC and GBC. Receiver operating characteristic (ROC) curve was conducted and the area under the curve (AUC) was managed to evaluate the validity. Results The carcinoembryonic antigen (CEA) level in blood tests was significantly elevated in GBC patients than in XGC patients (p = 0.007). The presence of submucosal hypo‐attenuated nodules (80% in XGC, 16% in GBC, p < 0.001), low density border (60% in XGC, 21% in GBC, p = 0.001), and nodular thickening in the bottom of the gallbladder with calcification (70% in XGC, 37% in GBC, p = 0.004) is significantly associated with XGC patients, whereas massive hilar infiltration (0% in XGC, 21% in GBC, p < 0.001), multiple lymph nodes in the hilar area (10% in XGC, 72% in GBC, p = 0.001), and gallbladder mucosal line continuity (50% in XGC, 95% in GBC, p = 0.002) are highly associated with GBC patients. The ROC curve was performed and the gallbladder mucosal line continuity (AUC = 0.708) and the AUC of low density border around the occupation (AUC = 0.654) showed a good prediction of XGC. Conclusions Gallbladder mucosal line continuity and low density border around the occupation presented good indication value for the diagnosis of XGC. Our study proposed a noninvasive differential diagnosis method for XGC and GBC.

Abstract
Chronic follicular cholecystitis (CFC) is a rare pathology characterized by prominent lymphoid follicles in the lamina propria distributed throughout the gallbladder wall. It has also been mentioned in the literature as lymphoid hyperplasia and pseudolymphoma. CFC represents less than 2% of cholecystectomies. Its etiopathology is mostly unknown. Most reports are based on histopathological findings, with little or no imaging analysis. We describe a case involving a 66-year-old man radiologically diagnosed as xanthogranulomatous cholecystitis (XGC) versus malignancy, revealing CFC with surrounding inflammatory changes in the cholecystectomy specimen.

Abstract
Introduction Gallbladder cancer (GBC) is the most common malignancy, representing 80-95% of biliary tract cancers. Although ultrasonography-guided fine-needle aspiration cytology (USG-FNAC) has emerged as an effective diagnostic the tool for the precise diagnosis of gallbladder lesions, data on its diagnostic utility and cytomorphological categorization of gallbladder lesions are lacking. Aims To study the diagnostic utility of USG-FNAC in gallbladder lesions. Materials and Methods This study was the conducted prospectively on patients who came with clinical and radiological evidence of gallbladder space-occupying lesion and then advised to USG-FNAC over 2 years and 6 months from January 2018 to June 2020. Results A total of 314 cases were included. The mean age was 56 years, with a range of 17-88 years. Women predominated over men (Male:Female = 1:2.3). Primary adenocarcinoma of the gallbladder was most common. On cyto-histological correlation, the sensitivity, specificity, and diagnostic accuracy of USG-FNAC of gallbladder lesions were found to be 98.82, 87.23, and 96.3%, respectively. Conclusion The USG-FNAC of gallbladder lesion was found to be an easy, quick, cost-effective, and presumptive diagnostic procedure. It should be opted as an initial preoperative diagnostic modality in high incidence areas to avoid inappropriate management with unnecessary morbidity and cost. Moreover, a close cytological examination of the architectural pattern and the cytomorphological features would help in the sub-typing and prognosticating the tumor.

Abstract
Background/Aim Xanthogranulomatous cholecystitis (XGC) is a rare destructive inflammatory disease of the gallbladder. It is frequently misdiagnosed as gallbladder carcinoma (GBC) as it mimics latter with regard to clinical manifestations, imaging and intraoperative findings, often leading to extended surgical resection in these patients. The aim of this study was to evaluate the diagnostic dilemma of XGC cases clinico-radiologically diagnosed with GBC. Materials and Methods From January 2017 to June 2019, a total of eight cases histopathologically diagnosed as XGC, were misdiagnosed with GBC based on preoperative and intra-operative findings. The clinical characteristics, imaging, intra-operative findings, and surgical data of these patients were collected and analyzed. Results A total of 2154 cholecystectomy specimens were received in the histopathology section during the study period. Sixty-nine cases (3.2%) were histologically diagnosed as XGC, of which 8 cases (11.6%) were preoperatively diagnosed with GBC. These cases were predominantly seen in males in the age range of 24-62 years. The most common clinical presentation was chronic cholecystitis. Gallstones were present in all the 8 cases. Six cases presented with heterogeneous enhancement within thickened gallbladder walls on imaging. Intraoperatively, adhesions to adjacent organs were observed in seven cases. All these eight cases misdiagnosed with GBC underwent aggressive surgical treatment following which histopathology ultimately revealed XGC. Conclusion Neither clinical manifestations nor laboratory tests/radiological methods can provide an effective means of differentiating between XGC and GBC. Preoperative diagnosis is difficult, and histopathology remains the gold standard to differentiate the two entities.

Abstract
The abnormal thickening of the gallbladder (GB) wall can be caused by a malignant condition like gallbladder carcinoma or by benign lesions such as chronic cholecystitis or xanthogranulomatous cholecystitis (XGC). Mural thickening is a common finding between them as fluorodeoxyglucose (FDG) can be taken up by inflammatory cells also. Here, we present a patient with irregular thickening of the GB wall which was suspected to of GB carcinoma since FDG positron emission tomography/computed tomography scan showed increased tracer uptake in the lesion. However, after surgery the histopathological report was suggestive of XGC.

Abstract
Xanthogranulomatous cholecystitis (XGC) is a rare inflammatory disease of the gallbladder characterized by severe proliferative fibrosis and the accumulation of lipid-laden macrophages in areas of destructive inflammation. Misdiagnosis is highly usual, and its macroscopic appearance may often be confused with gallbladder carcinoma. Here we discuss the case of a 56-year-old male who presented in the emergency room with fever, chills, and nausea. The routine laboratory investigations were normal except for elevated white blood cell counts. Abdominal ultrasound showed borderline gallbladder wall thickening. However, after CT scan findings, the suspect diagnosis of acute cholecystitis with possible perforation was made and the cholecystectomy was performed. The definitive diagnosis was delayed until the final pathology result came as a surprise, and later confirmed the histologic diagnosis of XGC. We consider this an important case because of the histopathologic finding of fibrotic thickened gallbladder wall with abundant histiocytes and pericholecystic fat stranding along with perforation and extensive inflammatory changes in the right upper quadrant of the abdomen which is highly suggestive and indicative of XGC in comparison to gallbladder carcinoma (GC). All things considered, clinically and grossly XGC presents in a similar fashion as GC; histopathology confirmed the diagnosis of XGC.

Abstract
Introduction: Xanthogranulomatous cholecystitis (XGC) is a rare inflammatory disease of the gallbladder (GB). XGC surgery is a difficult process due to its clinical, radiological, and intraoperative findings. In this study, our aim is to show the difficulties of XGC surgery and to find out if laparoscopic surgery is a sufficient procedure. Materials and Methods: Histological findings of 3339 cholecystectomy patients, who were operated between January 2015 and January 2020, were retrospectively reviewed. Age, gender, radiological results, clinical features, intraoperative findings, and surgical management of the patients with XGC were recorded. Results: XGC was observed in 70 patients (2.09%). The average age was 53.75. M:F ratio was 1.2. In radiological examinations, gallstones were found in 94.2% of the patients and GB wall thickness (≥3 mm) was increased in 58.5% of the patients. Around 45.7% of the patients came to the clinic with chronic cholecystitis and 32.9% with acute cholecystitis. In the intraoperative period, adhesions were observed in 80% and increase in GB wall thickness was observed in 77.1% of the patients. The operation started laparoscopically in 66 patients. In 14 patients (21.2%), it was converted to open surgery usually due to insufficient dissection of Calot's triangle. Gallbladder carcinoma (GBC) was suspected in 6 patients, but none of them had malignancy in frozen sections or histology. Conclusions: XGC surgery is difficult due to its radiological, clinical, and intraoperative features and mimicking GBC. It can be converted to open cholecystectomy due to difficulties in laparoscopic dissection. However, since conversion cholecystectomy rates are reasonable, laparoscopic surgery is recommended in patients with suspected XGC.

Abstract
Gallbladder wall thickening, associated with features like perforation, fistula formation and invasion of adjacent organs, is often assumed to be malignant. Xanthogranulomatous cholecystitis (XGC) causes gallbladder wall thickening with similar aggressive features and closely mimics gallbladder carcinoma clinically, radiologically and surgically. Differentiating between these two is crucial for management as misdiagnosis of gallbladder cancer can lead to unnecessary radical surgery. We report a case of chronic gallbladder wall thickening, initially suspected to be malignant, but subsequently diagnosed as XGC.

Abstract
Xanthogranulomatous cholecystitis (XGC) is a rare inflammatory disease of the gallbladder with distinct histopathological characteristics. Laparoscopic cholecystectomy (LC) is currently the standard treatment for gallbladder disease. However, the outcomes of LC for XGC have not been completely investigated, due to the rarity of XGC. The present study aimed to assess the surgical outcomes of LC for XGC. Among 3,037 patients undergoing cholecystectomy between 2005 and 2017 at our institution, 58 patients (1.9%) were diagnosed with XGC based on histopathology. Of the patients, LC was performed in 38 (65.5%), and they were enrolled in the present study. The outcome of LC for XGC in the cases was assessed, and was compared with outcomes of LC for other diseases. The average operation time was 109±36 min, and average intraoperative blood loss was 58±85 ml. LC was converted to open cholecystectomy in 6 (15.8%) of the 38 cases. No operative mortality occurred. One patient developed postoperative complications greater than grade II in the Clavien-Dindo classification, and the mean postoperative hospital stay was 6.1±5.8 days. Based on previous reports and the nature of XGC itself, the outcomes reported herein of LC for XGC seemed acceptable. It should be also noted that LC for XGC exhibited a higher conversion rate compared with LC than other benign gallbladder diseases, implying that LC for XGC remains challenging.

Abstract
Background: Xanthogranulomatous cholecystitis (XGC) is an uncommon inflammatory disease of gallbladder (GB) and can mimic GB cancer in extensive form. This study aims to assess the predictability of XGC on the basis of clinical presentation, laboratory tests, and radiological or intraoperative findings on frozen section analysis. Materials and Methods: This is a retrospective study, conducted over a period of 4 years from October 2013 to November 2017. In this study, all patients with histopathological reports of XGC, who underwent cholecystectomy or a radical cholecystectomy, were included. Clinical records of these patients were reviewed for clinical features, laboratory tests, and findings on radiological imaging. Results: Out of 700 consecutive cholecystectomies reviewed, 34 had histologically proven XGC (4.85%). Two patients had simultaneous presence of GB carcinoma with XGC. The most common presenting symptoms were right upper quadrant pain in 32 (94%) patients, jaundice in 9 (36%) patients, and fever in 5 (14%) patients. The most common radiological finding was cholelithiasis in 85.2% of cases. Thick-walled GB was present in 79.4% of patients; irregular wall thickening was present in 20.5% of patients. Intramural nodule was present in two patients, whereas hepatic invasion was observed in 11% and pericholecystic infiltration was present in 8.8% of patients. Regional lymphadenopathy was present in 9 (26.4%) patients. Conclusion: Clinical presentation and laboratory parameters were unequivocal due to considerable overlap. Despite recent advances in radiology, none have significant sensitivity and specificity to accurately diagnose XGC preoperatively. Intraoperative frozen section can add to the diagnosis with limited accuracy. The diagnosis of XGC can be confirmed only on histopathological examination.

Abstract
A 67-year-old woman presented with clinical symptoms, radiological findings, and preoperative work-up highly suggestive of advanced stage IV carcinoma of the gallbladder (CG). An extended cholecystectomy with the excision of adjacent liver segments and loco-regional lymphadenectomy was performed. Final pathology results revealed diffuse xanthogranulomatous cholecystitis (XG) with ruptured Rokitansky-Aschoff sinuses with tumor-resembling adenomyosis without atypical or malignant cells. There was a reactive inflammatory and fatty degeneration of the adjacent hepatic tissue and a nonspecific inflammatory reaction of the enlarged periportal lymph nodes. The main concern in the management of patients with mass-forming XG is that this benign condition shares strikingly similar clinical, imaging, biochemical, and intraoperative features with advanced CG, which has one of the poorest overall survival rates. Misdiagnosis is not uncommon, which causes significant distress for patients and their families and, in some cases, may result in erroneous treatment. Although the presence of some preoperative imaging findings and/or intraoperative frozen section biopsies may be helpful in suspecting XG, definitive diagnosis is usually delayed until the final pathology result that may come as a surprise. Increasing awareness of this rare, insidious disease will contribute to a better understanding of its biology and natural history and, eventually, help improve management.

Abstract
OBJECTIVE Fine needle aspiration (FNA) is not a commonly performed procedure for gallbladder lesions for fear of causing biliary peritonitis; hence data on gallbladder cytology is scarce. The aims of the present study were to evaluate the diagnostic application of ultrasound-guided (US) FNA cytology in the pre-operative diagnosis of neoplastic as well as non-neoplastic lesions of the gallbladder and to review the cytomorphological spectrum of gallbladder lesions encountered along with various diagnostic difficulties that can arise during reporting. METHODS The study was carried out on 596 patients with gallbladder lesions in whom US-guided FNA was performed over a 5-year period. In 130 cases, simultaneous aspirations from other organs were done. The histological correlation was available in 32 cases. No major complications such as haemorrhage, peritonitis, etc. were encountered related to the procedure. RESULTS The majority were mass lesions whereas in 73 cases (12.2%) only focal or diffuse gallbladder wall thickening was present. Cytological examination of 596 cases revealed malignancy in 462 (77.6%), 26 (4.4%) suspicious of malignancy, 23 (3.8%) inflammatory lesion, 29 negative (4.8%) and 56 cases showed necrosis only or were inadequate for any definite opinion. The lesions diagnosed on FNA cytology included carcinoma (predominantly adenocarcinoma), xanthogranulomatous cholecystitis (XGC), acute suppurative inflammation and tuberculosis. Of 26 with adequate cytology, 24 were accurate with respect to malignant (including one suspicious FNA) versus benign: one false positive and one false negative both involved xanthogranulomatous change. CONCLUSION The present study is the largest series evaluating the role of US-guided FNA in the diagnosis of gallbladder lesions. It is a safe, rapid, reliable, cost-effective and reasonably accurate method for diagnosing gallbladder lesions. FNA should always be attempted in cases with a mass lesion.

Abstract
BACKGROUND AND AIM Angiogenesis plays a key role in growth, progression, and metastasis of various cancers. Vascular endothelial growth factor (VEGF) polymorphism has been associated with several cancers. Role of VEGF has not been reported in gallbladder cancer (GBC). Present study was designed to investigate the role of VEGF polymorphism in GBC and in other (benign) gallbladder diseases, that is chronic cholecystitis (CC) and xanthogranulomatous cholecystitis (XGC). METHODS Blood samples were collected from 195 GBC, 140 CC, and 47 XGC patients and 300 normal healthy controls. VEGF polymorphisms were investigated using amplification refractory mutation system polymerase chain reaction for g.43737830A>G and g.3437A>C, polymerase chain reaction-restriction fragment length polymorphism for c.*237C>T, and g.43736418delTinsG amplified by polymerase chain reaction. RESULTS At g.43737830A>G, GA genotype showed susceptibility (odds ratio [OR] = 1.65 and OR = 1.68) and GG genotype showed protective association (OR = 0.58 and OR = 0.50) with GBC and CC. Allele A of VEGF g.43737830A>G was risk associated with GBC and CC (OR = 1.48 and OR = 1.70), while G allele was risk protective for GBC and CC (OR = 0.67 and OR = 0.58). At g.3437A>C, genotype CA was risk protective for GBC (OR = 0.61). TT genotype of c.*237C>T was susceptible for GBC and CC (OR = 2.59 and OR = 3.48), while CC genotype was risk protective for GBC and CC (OR = 0.61 and OR = 0.34). T allele of c.*237C>T polymorphism was risk associated with GBC and CC (OR = 1.63 and OR = 2.90), while C allele was risk protective for GBC and CC (OR = 0.38 and OR = 0.28). Haplotype I-C-A-C was risk protective for GBC (OR = 0.27). CONCLUSION The present study suggests that c.*237C>T and g.43737830A>G polymorphisms are useful markers of susceptibility to GBC.

Outcomes of Xanthogranulomatous cholecystitis in laparoscopic era: A retrospective Cohort study. J Minim Access Surg 2013; 9:109-15. [PMID: 24019688 PMCID: PMC3764653 DOI: 10.4103/0972-9941.115368] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2012] [Accepted: 09/21/2012] [Indexed: 12/31/2022] Open
Abstract
INTRODUCTION: Xanthogranulomatous cholecystitis (XGC) is a rare variant of cholecystitis and reported incidence of XGC varies from different geographic region from 0.7% -9%. Most of the clinicians are not aware of the pathology and less evidence is available regarding the optimal treatment of this less common form of cholecystitis in the present era of laparoscopic surgery. MATERIALS AND METHODS: A retrospective cohort study was conducted in a tertiary care university hospital from 1989 to 2009. Histopathologically confirmed XGC study patients (N=27) were compared with non-Xanthogranulomatous cholecystitis (NXGC) control group (N=27). The outcomes variables were operative time, complication rate and laparoscopic to open cholecystectomy conversion rate. The study group (XGC) was further divided in to three sub groups; group I open cholecystectomy (OC), laparoscopic cholecystectomy (LC) and laparoscopic converted to open cholecystectomy (LCO) for comparative analysis to identify the significant variables. RESULTS: During the study period 6878 underwent cholecystectomy including open cholecystectomy in 2309 and laparoscopic cholecystectomy in 4569 patients. Histopathology confirmed xanthogranulomatous cholecystitis in 30 patients (0.43% of all cholecystectomies) and 27 patients qualified for the inclusion criterion. Gallbladder carcinoma was reported in 100 patients (1.45%) during the study period and no association was found with XGC. The mean age of patients with XGC was 49.8 year (range: 29-79), with male to female ratio of 1:3. The most common clinical features were abdominal pain and tenderness in right hypochondrium. Biliary colic and acute cholecystitis were the most common preoperative diagnosis. Ultrasonogram was performed in all patients and CT scan abdomen in 5 patients. In study population (XGC), 10 were patients in group I, 8 in group II and 9 in group III. Conversion rate from laparoscopy to open was 53 % (n=9), surgical site infection rate of 14.8% (n=4) and common bile duct injury occurred one patient in open cholecystectomy group (3.7%). Statistically significant differences between group I and group II were raised total leukocyte count: 10.6±3.05 vs. 7.05±1.8 (P-Value 0.02) and duration of surgery in minutes: 248.75±165 vs. 109±39.7 (P-Value 0.04). The differences between group III and group II were duration of surgery in minutes: 208.75±58 vs. 109±39.7 (P-Value 0.03) and duration of symptoms in days: 3±1.8 vs. 9.8±8.8 (P-Value 0.04). The mean hospital stay in group I was 9.7 days, group II 5.6 days and in group III 10.5 days. Two patients underwent extended cholecystectomy based on clinical suspicion of carcinoma. No mortality was observed in this study population. Duration of surgery was higher in XGC group as compared to controls (NXGC) (203±129 vs.128±4, p-value=0.008) and no statistically significant difference in incidence proportion of operative complication rate were observed among the group (25.9% vs. 14.8%, p-value=0.25. Laparoscopic surgery was introduced in 1994 and 17 patients underwent laparoscopic cholecystectomy and higher conversion rate from laparoscopic to open cholecystectomy was observed in 17 study group (XGC) as compared to 27 Control group (NXGC) 53%vs.3.3% with P-value of < 0.023. CONCLUSION: XGC is a rare entity of cholecystitis and preoperative diagnosis is a challenging task. Difficult dissection was encountered in open as well in laparoscopic cholecystectomy with increased operation time. Laparoscopic cholecystectomy was carried out with high conversion rate to improve the safety of procedure. Per operative clinical suspicion of malignancy was high but no association of XGC was found with gallbladder carcinoma, therefore frozen section is recommended before embarking on radical surgery.

Ascariasis of gall bladder associated with xanthogranulomatous inflammation and cholelithiasis. Trop Parasitol 2011; 1:138-40. [PMID: 23508547 PMCID: PMC3593482 DOI: 10.4103/2229-5070.86968] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2011] [Accepted: 10/31/2011] [Indexed: 11/04/2022] Open
Abstract
We report a rare case of ascariasis of gall bladder. The unusual features in this case were the presence of eggs of Ascaris lumbricoides in the lumen. Some of the eggs had evoked a foreign body reaction indicating chronicity. The bladder wall was unevenly thickened with yellowish white nodules and showed maximum thickness around the neck region. Microscopy showed predominantly xanthogranulomatous inflammation in the thickened parts of the wall.

Abstract
BACKGROUND Acute cholecystitis resolves with conservative treatment in most patients, but empyema or perforation of an ischaemic area may develop, resulting in a pericholecystic abscess, bile peritonitis or a cholecysto-enteric fistula. CASE OUTLINE A 63-year-old man presented with extraperitoneal and omental abscess formation complicating a cholecystocolic fistula secondary to gallbladder disease. Histological examination of the gallbladder and omentum showed xanthogranulomatous inflammation. CONCLUSION A detailed literature review failed to demonstrate a previous report of this combination of rare complications of gallbladder disease.

Abstract
Xanthogranulomatous cholecystitis (XGC) is an uncommon, focal or diffuse destructive inflammatory disease of the gallbladder that is assumed to be a variant of conventional chronic cholecystitis. A 36-year-old male was admitted to Chonnam National University Hospital with a 10-day history of right upper quadrant pain with fever. 15 years ago, he was first diagnosed as having hemophilia A, and has been followed up in the department of Hematology. Computed tomogram (CT) revealed a well-marginated, uniform, marked wall thickening of the gallbladder with multiseptate enhancement. Magnetic resonance imaging (MRI) demonstrated diffuse wall thickening of the gallbladder by viewing high signal foci with signal void lesions. After factor VIII replacement, exploration was done. On operation, the gallbladder wall was thickened and the serosa were surrounded by dense fibrous adhesions which were often extensive and attached to the adjacent hepatic parenchyma. There was a small-sized abscess in the gallbladder wall near the cystic duct. Dissection between the gallbladder serosa and hepatic parenchyma was difficult. Cross sections through the wall revealed multiple yellow-colored, nodule-like lesions ranging from 0.5-2 cm. There were also multiple black pigmented gallstones ranging from 0.5-1 cm. The pathologic findings showed the collection of foamy histiocytes containing abundant lipid in the cytoplasm and admixed lymphoid cells. Histologically, it was confirmed as XGC. We report a case with XGC mimicking gallbladder cancer in a hemophilia patient.
