RESUMO
BACKGROUND: Laparoscopic cholecystectomy (LC) is the gold standard management for benign gallbladder diseases. It has been observed that there is alteration in vitamin D levels and bone mineral density after cholecystectomy due to altered enterohepatic circulation. With increase in average age expectancy of the population, low levels of vitamin D levels and osteoporosis after cholecystectomies might cause increased health care burden. METHODS: A prospective observational study was planned between 1 January 2022 and 30 June 2023 in the Department of General Surgery at PGIMER Chandigarh, a tertiary care hospital in north India. One hundred and three post-menopausal women who underwent LC and met the inclusion and exclusion criteria were included in the study. All participants underwent estimation of vitamin D and bone mineral density preoperatively and third-post operative month (POM). RESULTS: The mean age of the patients was 58.46 ± 7.44. Pain abdomen was present in 68(66%) patients, 18 had epigastric discomfort and 17 had dyspepsia. The mean levels of vitamin D decreased from 21.92 at the baseline to 20.12 at third POM (p < .001). There was a significant change in t score Femoral Neck (-1.12 vs -1.15, p < .001) and Lumbar spine L1-L4 - 1.98 vs -1.98 (p = .033). z-scores of the femoral neck were -0.34 vs -0.54 (p < .001) and of lumbar spine L1-L4 were -0.95 vs 1.02 (p < .001). The decrease in fracture risk for the femoral neck (p = .344) and the lumbar spine (p = .223) was not statistically significant. CONCLUSION: There is a significant decrease in vitamin D and BMD levels after LC in post-menopausal females.
RESUMO
AIM AND OBJECTIVES: To assess the effect of gallstone disease on liver parenchyma and the prevalence and extent of liver pathology in cholelithiasis in our population at the Department of General Surgery, Indira Gandhi Institute of Medical Science (IGIMS), Patna. MATERIAL AND METHODS: The present prospective observational study was conducted on 100 either-sex patients scheduled for open or laparoscopic cholecystectomy. In all the patients, laboratory and radiological investigations were performed. An undamaged portion of the liver edge around the gallbladder fossa was selected and held by atraumatic forceps. Using sharp scissors, around 1 cm of the liver edge was taken out and sent for histopathological examination. RESULTS: The mean age of the patients was 39.28 ± 13.73 years. The majority of patients were females (69%). Pain was the predominant clinical feature in 51% of the patients, followed by vomiting (21%), nausea (18%), and indigestion (10%). In 36% of cases, the liver histology was abnormal, including steatosis, fibrosis, cholestasis, portal tract infiltration, and lobular parenchymal infiltration. A significant association was found between the duration of symptoms and abnormal histology findings (P<0.0001). CONCLUSION: Gallstone disease is associated with notable alterations in liver histology, and these changes tend to be more prevalent in individuals with a prolonged duration of symptoms.
RESUMO
Gallstone disease (GSD) is a prevalent health condition that impacts many adults and is associated with presence of stones in gallbladder cavity that results in inflammation, pain, fever, nausea and vomiting. Several genome-wide association studies (GWAS) in the past have identified genes associated with GSD but only a few were focused on Latino population. To identify genetic risk factors for GSD in Latino population living in the Southwest USA we used self-reported clinical history, physical and lab measurements data in Sangre Por Salud (SPS) cohort and identified participants with and without diagnosis of GSD. We performed a GWAS on this phenotype using GSD cases matched to normal controls based on a tight criterion. We identified several novel loci associated with GSD as well as loci that were previously identified in past GWAS studies. The top 3 loci (MATN2, GPRIN3, GPC6) were strongly associated with GSD phenotype in our combined analysis and a sex stratified analysis results in females were closest to the overall results reflecting a general higher disease prevalence in females. The top identified variants in MATN2, GPRIN3, and GPC6 remain unchanged after local ancestry adjustment in SPS Latino population. Follow-up pathway enrichment analysis suggests enrichment of GO terms that are associated with immunological pathways; enzymatic processes in gallbladder, liver, and gastrointestinal tract; and GSD pathology. Our findings suggest an initial starting point towards better and deeper understanding of differences in gallstone disease pathology, biological mechanisms, and disease progression among Southwest US Latino population.
RESUMO
Gallstones causing bowel obstruction, known as gallstone ileus, are rare and account for less than 0.5% of small bowel obstruction cases. Additionally, it is a rare complication affecting only 0.3% of patients who have gallstones. Fistula formation between the biliary system, most commonly between the gallbladder and duodenum because of their proximity, facilitates the migration of gallstones into the enteric system with subsequent impaction in the small intestine, usually in the distal ileum close to the ileocecal valve, promoting the development of mechanical small bowel obstruction. Computerized tomography of the abdomen and pelvis is a confirmatory and widely used imaging study when there are two signs of Rigler's triad, which includes pneumobilia, evidence of small bowel obstruction and the presence of radiopaque stones. We report a case of a 75-year-old Caucasian man who presented with abdominal distention with signs of severe dehydration secondary to intractable nausea and vomiting complicated with severe acute kidney injury and was found to have a 4.7-centimeter gallstone-induced small intestinal obstruction.
RESUMO
Background The gold standard management for symptomatic gallstone disease is elective laparoscopic cholecystectomy, which has replaced open cholecystectomy. The wall thickness of the gallbladder is an indicator of cholecystitis in patients who have presented with symptoms of gallstone disease. The aim of this study was to evaluate preoperative gall bladder wall thickness by ultrasonography and assess its impact on the outcome of laparoscopic cholecystectomy, including conversion rate, complications, operative time, and postoperative hospital stay. Method This prospective study was conducted on 350 patients with symptomatic gallstone disease, those who had undergone laparoscopic cholecystectomy in Dr. Sampurnanand Medical College, Jodhpur, and attached hospitals from July 2019 to November 2021. On the basis of ultrasonography findings of gallbladder wall thickness, patients were divided into four groups: normal thickness - up to 2 mm, mild thickness - 3-4mm, moderate thickness - 5-6mm, and severe wall thickness - more than 6mm). Up to 2 millimeters thickness was considered as normal. Results The incidence of conversion rate, as well as intra or postoperative complications, were higher in moderate and severe wall thickness groups. The maximum incidence of complication rate is seen in moderately thickened group (33.33%). In severely thickened group, complication was seen in 100% of patients. Operative time, as well as postoperative hospital stay, were more in higher thickness groups. There was a statistically significant correlation between gallbladder wall thickness and conversion rate, complications operative time, and postoperative length of stay. Conclusion Increased gallbladder wall thickness causes increased intra as well as postoperative complications, more conversion to open procedure rate, increased operative time, and enhanced postoperative hospital stay. Among the total study population, 29.71% of patients had increased gallbladder wall thickness. In our study, a positive correlation was seen among gallbladder wall thickness, complication rate, conversion rate, intraoperative time, and postoperative hospital stay.
RESUMO
Pancreatic pseudocysts are fluid-filled collections that can arise from acute or chronic pancreatitis and may lead to a range of complications, like rupture, infection, hemorrhage, etc. Morbid obesity may further complicate the diagnosis and management of such cases. The present report describes the case of a 26-year-old superobese female (BMI: 58 kg/m²) with a pancreatic pseudocyst that presented diagnostic challenges and mimicked pulmonary embolism when the pseudocyst had ruptured. The patient initially presented with persistent biliary colic due to gallstones. Despite undergoing laparoscopic cholecystectomy, she continued to experience symptoms, including nausea, bloating, and inability to tolerate food, and lab tests showed progressive elevation of serum bilirubin levels. A huge pancreatic pseudocyst was found to be obliterating the gastric cavity and compressing the common bile duct after the patient was subjected to further radiological imaging. While waiting to be transferred to a tertiary center with endoscopic retrograde cholangiopancreatography (ERCP), endoscopic stenting, and other facilities, she suddenly experienced severe symptoms, like shortness of breath, upper abdominal/chest pain, tachycardia (heart rate: 140 beats per min), dizziness, and low oxygen saturation. The likelihood of pulmonary embolism (PE) was very high in the differential diagnoses, but computer tomography pulmonary angiography (CTPA) ruled out PE. Based on imaging and clinical assessment, rupture of the pancreatic pseudocyst was diagnosed. The patient was subsequently managed in a tertiary hospital endoscopically. This case highlights the challenges of diagnosing and managing pancreatic pseudocysts in extremely obese patients. It also underscores the role of a multidisciplinary approach and vigilant clinical attention to prevent misdiagnosis and optimize outcomes.
RESUMO
Double gall bladder or duplication of the gall bladder is a rare congenital malformation. It poses a challenge to the surgeon and the radiologist, both in preoperative evaluation and intraoperative management. In the era of minimal invasive surgery, clear knowledge of extrahepatic biliary anatomical variations is very much essential. The operating surgeon should be very careful and overcautious in identifying such variations to prevent untoward biliary tract injury. In this series of two cases, we present the clinical peculiarities, preoperative diagnosis, and laparoscopic management of the duplicate gall bladder.
RESUMO
Gallstone ileus is a rare complication of cholelithiasis seen in patients with a long history of cholelithiasis. It occurs more in the older age group and in the female gender. These patients have poor general condition and therefore selection of appropriate treatment is difficult. The clinician has to make a decision between immediate one-stage or two-stage closure of the cholecysto-intestinal fistula or waiting for natural closure. We have discussed the management of a rare cause of small bowel obstruction due to complication of untreated cholelithiasis.
RESUMO
Needle knife papillotomy has become an invaluable advanced biliary access technique in routine endoscopic retrograde cholangiopancreatography (ERCP). Albeit poorly standardized in terms of procedural details, usually superficial cuts are applied to open the bile duct in an onion-like manner. However, this implies the capability to direct cuts from some distance from the papilla controlling needle knife movements in a complex fashion involving elevator movements. Here, an as-yet unreported technique designated the "lever technique" is presented for difficult needle knife access, when encountering technical difficulties, such as unstable scope position and awkward bile duct angle to allow for controlled needle knife navigation. In such variant rescue approach involving well-characterized prepapillary stone impaction by preceding same-session endoscopic ultrasound (EUS), thus providing some safety plane, ultranear-view instrumentation is coupled with exclusive needle knife navigation by moving the large dial, thus moving scope and needle knife-like as one endoscopic device.

RESUMO
AIM: To evaluate the role of preoperative magnetic resonance cholangiopancreatography (MRCP) in detection of common bile duct stone (CBDS) in cases of gall stone disease (GSD). METHODS: This is a retrospective study with a prospectively maintained database, carried out in 116 patients who underwent laparoscopic cholecystectomy (LC) for GSD, from October 2017 to September 2020. Preoperative MRCP was performed in all cases. RESULTS: MRCP detected CBDS in 23 out of 116 patients (19.8%) including silent CBDS in seven patients (6%). In situations of normal biochemical parameters and USG abdomen, 30.4% unnoticed CBDS out of all 23 CBDS, were discovered by MRCP. The sensitivity and specificity of aspartate aminotransferase (AST) or alanine aminotransferase (ALT) [positive predictive value (PPV): 24%; negative predictive value (NPV): 81.3%], alkaline phosphatase (ALP) (PPV: 63.2%; NPV: 88.7%), serum total bilirubin (PPV: 57.1%; NPV: 88.4%) and CBD diameter (PPV: 61.5%; NPV: 85.4%) were, respectively, 26.1% and 79.6%, 52.2% and 92.5%, 52.2% and 90.3%, and 34.8% and 94.6%. Cystic duct variations found in nine patients (7.75%). There was no bile duct injury (0%) noted in post operative patients. CONCLUSION: With normal biochemical and USG parameters, MRCP is a valuable non-invasive investigation to detect the overlooked CBDS. After recognising the cystic duct variants, it may be possible to prevent bile duct injury. Before performing a laparoscopic cholecystectomy (LC) in GSD, a routine preoperative MRCP is highly recommended.
RESUMO
BACKGROUND: Gall stone disease (GSD) is one of the commonest gastrointestinal disorders. Causative factors can be non-modifiable as genetics and modifiable like dietary habits. High-fat diet and high BMI are well known contributing factors world-over. Local and regional data is deficient about these factors. Moreover, Indo-Pakistani dietary patterns are very different from the western population. This study was conducted to see the association of high BMI and diet with GSD in our population. MATERIALS AND METHODS: This case-control study was conducted in Shifa International Hospital, Islamabad, from 2012 to 2017. We included all female patients above 25 years of age with symptomatic gall stones on ultrasonography as cases and all females above 25 years of age with no gall stones on ultrasonography (done for any reason) as controls. The patients with gall stones having some other clear predisposing cause for gallstone formation, e.g., stoma, sudden weight loss, etc. were excluded. BMI, demographic details, dietary habits, and clinical profile of cases and controls were recorded. Data were analyzed by SPSS v 21. p-values were calculated. RESULTS: A total of 396 patients were included in this study, with 103 cases and 293 controls. The mean BMI of GSD cases was 27.576±5.753, while controls had a mean BMI of 25.638±7.008 (p=0.08). About 26.4% of cases had an average fat consumption greater than 100g/day as compared to 11.9% controls (p=0.035). The average red meat intake per week was 222g among cases while 210g among controls (p=0.001). The average intake of fried food per week was 270g among controls and 250g among cases (p=0.012). The average intake of bakery items per week was 240g among cases and 210g among controls (p=0.038). CONCLUSION: Gall stone disease is significantly related to high BMI and high dietary fat and meat intake in our population.
RESUMO
BACKGROUND: Carcinoma of the gall bladder (GB) is the most common malignancy of the gastrointestinal tract. One percent of cholecystectomy specimens show incidental gall bladder cancers (GBCs). AIM: Our aim of the study to was evaluate the utility of routine histopathology of cholecystectomy specimens removed with a diagnosis of gall bladder diseases (GBD). MATERIALS AND METHODS: A retrospective study was done reviewing the histopathological records of 906 patients who underwent cholecystectomy. Demographic details, gross findings, and microscopic findings noted. All the cases were categorized into two groups, A and B. Group A included the cases with any gross abnormality including wall thickness ≥4 mm and group B included rest of the cases. RESULTS: Majority of the patients were in the age group of 31-40 years of age. Out of 906 patients studied, majority of them were females with F:M ratio of 6.14:1. Of the 47 cases which were included in group A (with macroscopic abnormality), six cases had gall bladder carcinoma on microscopy. One case from group B with macroscopically normal-appearing GB had invasive carcinoma on microscopy. In our study, we found a sensitivity of 85.71% and specificity of 95.44%, while positive predictive value (PPV) was 91.11% and negative predictive value (NPV) was 99.65% of macroscopic abnormality in the diagnosis of invasive carcinoma. CONCLUSION: All cholecystectomy specimens must be examined by histopathologists who must decide whether processing for microscopy is needed. Microscopic examination may be reserved for the specimen with a macroscopic lesion. This will result in a reduction of costs and pathology workload without compromising patient management.

BACKGROUND: Laparoscopic surgeries are a risk factor for raised intracranial **pressure and neurological complications. Even though rare, the consequences may be severe. METHODS: One hundred and one patients of laparoscopic cholecystectomy were enrolled and were randomized into two groups: low-pressure 8 mm Hg (Group A) and high-pressure 14 mm Hg (Group B) carbon dioxide pneumoperitoneum during surgery. Fifty patients were in group A and 51 patients were in group B. Intracranial pressure was measured by measuring the optic nerve sheath diameter (ONSD) using ultrasound examination. Baseline ONSD was recorded followed by ONSD recording at various intervals: at the induction of anesthesia; 30 min, 45 min, at the end of surgery; and 30 min post surgery. RESULTS: The groups were comparable in terms of demographics and comorbidities. The mean age of group A was 45 years and for group B it was 45.75 years. Most common indication for surgery was symptomatic gall stone disease. Baseline ONSD in group A was 0.427 ± 0.0459 mm, whereas it was 0.412 ± 0.0412 mm in group B. There was a significant rise of ONSD (p < 0.05) 30 min after induction of pneumoperitoneum and up to 30 min post anesthesia. In the low-pressure group 7 (14%) patients had a significant rise of ICP, whereas in the high-pressure group 20 (39%) patients had a significant rise of ICP (p < 0.05). CONCLUSIONS: High-pressure pneumoperitoneum causes significant rise in intracranial pressure in comparison to low-pressure pneumoperitoneum during laparoscopic cholecystectomy, which can be monitored by ONSD measurement by ultrasound examination and is totally non-invasive.

BACKGROUND: Cholecystectomy is considered the standard treatment for acute cholecystitis and symptomatic gallstones. An increasing number of frail elderly patients are being referred for this surgical treatment. A better understanding of surgical outcome in the elderly is needed to improve quality of care. METHODS: A retrospective analysis of 565 patients who underwent cholecystectomy was performed. Focus of the analyses was on postoperative complications and its predictors. RESULTS: The study population was divided in two cohorts; aged <70. More complications were found in patients aged ≥70 years. More elderly patients were admitted to the intensive care, respectively 4.0% and 14.1% (Pâ¯=â¯0.045). Hospital mortality was 6% in patients aged ≥70 years vs 0.6% in patients <70. CONCLUSION: In elderly patients, the complication and mortality rate following cholecystectomy is higher than previously reported. For high-risk patients aged ≥70 with cholecystitis, alternative therapies should be considered as a bridge to surgery or definite treatment.

BACKGROUND/OBJECTIVES: Individuals with Gilbert's syndrome (GS) harbor mutations in the UGT1A1 gene and are known to have elevated levels of bilirubin, which enhances the risk for gall stone formation. The aim of this study is to screen Indian patients with GS for the incidence of gall stone disease. METHODS: Individuals with persistently elevated serum bilirubin levels were genotyped for two polymorphisms (rs8175347; rs4148323) in UGT1A1 gene to confirm GS in them. Flanking regions of the above polymorphisms were amplified followed by direct sequencing. Ultrasonography was done to detect gallstone disease. Clinical data, including assessment of liver function, circulating levels of total and direct bilirubin, as well as routine hematological parameters were obtained as per standard procedures (Autoanalyzer). RESULTS: Of the total 1621 individuals subjected to genotyping, 1191 (1149 males of 29.6 ± 11.3 years with mean BMI of 22.1 ± 3.7 kg/m2 and 42 females of 30.8 ± 14.8 years with mean BMI of 20.9 ± 3.7 kg/m2) were confirmed to have GS. Gall bladder abnormalities including cholelithiasis (n = 106/1191; 8.9%), polyps (n = 18/1191; 1.5%) and gallbladder wall thickening (n = 17/1191; 1.4%) were noted. Incidence of gall stone disease was observed in 103 males (out of 1149) and 3 females (out of 42) indicating the risk of the disease to be 9.0% and 7.1% respectively in males and females with GS. CONCLUSION: Early recognition of GS by genetic analysis is required before these patients with intermittent episodes of jaundice run the risk of unnecessary operations on their bile ducts from the mistaken assumption ascribing the jaundice to a stone which has been left behind.
RESUMO
BACKGROUND: As on today, the global mortality rate of gallbladder cancer is still very high. Both genetic and epigenetic alterations play pivotal roles in the development of cancer. We selected seven tumour associated genes, implicated in other cancers, to assess their methylation status in gallbladder cancer and gallstone diseases. AIM OF STUDY: To study the promoter methylation of certain tumour associated genes in the molecular pathogenesis of gallbladder cancer and gall stone diseases. MATERIALS AND METHODS: Methylation specific PCR for seven tumour associated genes, viz., MASPIN, 14-3-3 sigma gene, THBS1, FLNC, HLTF, COX-2 and SOCS1, was performed in 50 gallbladder cancer (GBC), 30 gall stone diseases (GSD) and their respective adjacent control tissues. Semi-quantitative PCR and immunohistochemistry was carried out to check the expression level. Student's t-test was carried out to compare the differences in the methylation and expression patterns between cases and control tissues. RESULTS: We observed methylation of CpG islands in seven of the studied markers, but, the frequency of methylation was found varying among different samples. Of them, 14-33 sigma showed methylation in 45 GBC (90%; p=0.0001) and 25 GSD (86.66%; p=0.001), MASPIN in 35 GBC (70%; p=0.0008) and 18 GSD (51.43%; p=0.040), FLNC in 16 GBC (32%; p=0.0044) and 9 GSD (25.71%; p=ns), THBS1 in 26 GBC (52%; p=0.0009) and 10 GSD (28.57%; p=0.0505), HLTF in 8 GBC (16%; p=ns) and 2 GSD (5.71%; p=ns), COX2 in 10 GBC (20%; p=ns) and 6 GSD (17.14%; p=ns) and SOCS-1 in 3 GBC samples only (6%; p=ns), but not in GSD. Semi-quantitative PCR revealed down regulation in MASPIN, 14-3-3 sigma, THBS1, HLTF, COX2 and SOCS1 in advanced gallbladder cases. Immunohistochemistry further confirmed the down-regulation of SOCS1 in GBC. CONCLUSION: The present study infers that accumulation of epigenetic alterations increases poor prognosis of GBC patients. Out of seven genes, MASPIN and THBS1 play key epigenetic role in GBC, but not in GSD. The reason for downregulation of SOCS1 only in GBC, and unaltered expression of 14-3-3 sigma protein in all the GBC and GSD tissue samples is not clear. Further investigation on the expression pattern of these genes in GBC cell lines may elucidate their likely functional role in in association with gallbladder cancer.
