RESUMO
BACKGROUND & AIMS: Gallstones (cholelithiasis) constitute a major health burden with high costs related to surgical removal of the gallbladder (cholecystectomy), generally indicated for symptomatic gallstones. The association between gallstones and cholecystectomy and kidney cancer is controversial. We comprehensively investigated this association, considering age at cholecystectomy and time from cholecystectomy to kidney cancer diagnosis, and assessed the causal effect of gallstones on kidney cancer risk by Mendelian randomization (MR). METHODS: We compared the risk of kidney cancer in cholecystectomized and noncholecystectomized patients (16.6 million in total) from the Swedish nationwide cancer, census, patient, and death registries using hazard ratios (HRs). For 2-sample and multivariable MR, we used summary statistics based on 408,567 UK Biobank participants. RESULTS: During a median follow-up of 13 years, 2627 of 627,870 cholecystectomized Swedish patients developed kidney cancer (HR, 1.17; 95% CI, 1.12-1.22). Kidney cancer risk was particularly increased in the first 6 months after cholecystectomy (HR, 3.79; 95% CI, 3.18-4.52) and in patients cholecystectomized before age 40 years (HR, 1.55; 95% CI, 1.39-1.72). MR results based on 18,417 patients with gallstones and 1788 patients with kidney cancer from the United Kingdom revealed a causal effect of gallstones on kidney cancer risk (9.6% risk increase per doubling in gallstone prevalence; 95% CI, 1.2%-18.8%). CONCLUSIONS: Both observational and causal MR estimates based on large prospective cohorts support an increased risk of kidney cancer in patients with gallstones. Our findings provide solid evidence for the compelling need to diagnostically rule out kidney cancer before and during gallbladder removal, to prioritize kidney cancer screening in patients undergoing cholecystectomy in their 30s, and to investigate the underlying mechanisms linking gallstones and kidney cancer in future studies.

BACKGROUND: Data on the incidence and clinical relevance of gallstones in patients with suspected acute alcoholic pancreatitis are lacking and are essential to minimize the risk of recurrent acute pancreatitis. The aim of this study was to assess the incidence of gallstones and the associated rate of recurrent acute pancreatitis in patients with presumed acute alcoholic pancreatitis. METHODS: Between 2008 and 2019, 23 hospitals prospectively enrolled patients with acute pancreatitis. Those diagnosed with their first episode of presumed acute alcoholic pancreatitis were included in this study. The term gallstones was used to describe the presence of cholelithiasis or biliary sludge found during imaging. The primary outcome was pancreatitis recurrence during 3 years of follow-up. RESULTS: A total of 334 patients were eligible for inclusion, of whom 316 were included in the follow-up analysis. Gallstone evaluation, either during the index admission or during follow-up, was performed for 306 of 334 patients (91.6%). Gallstones were detected in 54 patients (17.6%), with a median time to detection of 6 (interquartile range 0-42) weeks. During follow-up, recurrent acute pancreatitis occurred in 121 of 316 patients (38.3%), with a significantly higher incidence rate for patients with gallstones compared with patients without gallstones (59% versus 34.2% respectively; P < 0.001), while more patients with gallstones had stopped drinking alcohol at the time of their first recurrence (41% versus 24% respectively; P = 0.020). Cholecystectomy was performed for 19 patients with gallstones (36%). The recurrence rate was lower for patients in the cholecystectomy group compared with patients who did receive inadequate treatment or no treatment (5/19 versus 19/34 respectively; P = 0.038). CONCLUSION: Gallstones were found in almost one in every five patients diagnosed with acute alcoholic pancreatitis. Gallstones were associated with a higher rate of recurrent pancreatitis, while undergoing cholecystectomy was associated with a reduction in this rate.

BACKGROUND AND AIMS: We compared ERCP using a balloon-assisted endoscope (BE-ERCP) with EUS-guided antegrade treatment (EUS-AG) for removal of common bile duct (CBD) stones in patients with Roux-en-Y (R-Y) gastrectomy. METHODS: Consecutive patients who had previous R-Y gastrectomy undergoing BE-ERCP or EUS-AG for CBD stones in 16 centers were retrospectively analyzed. RESULTS: BE-ERCP and EUS-AG were performed in 588 and 59 patients, respectively. Baseline characteristics were similar, except for CBD diameter and angle. The technical success rate was 83.7% versus 83.1% (P = .956), complete stone removal rate was 78.1% versus 67.8% (P = .102), and early adverse event rate was 10.2% versus 18.6% (P = .076) in BE-ERCP and EUS-AG, respectively. The mean number of endoscopic sessions was smaller in BE-ERCP (1.5 ± .8 vs 1.9 ± 1.0 sessions, P = .01), whereas the median total treatment time was longer (90 vs 61.5 minutes, P = .001). Among patients with biliary access, the complete stone removal rate was significantly higher in BE-ERCP (93.3% vs 81.6%, P = .009). Negative predictive factors were CBD diameter ≥15 mm (odds ratio [OR], .41) and an angle of CBD <90 degrees (OR, .39) in BE-ERCP and a stone size ≥10 mm (OR, .07) and an angle of CBD <90 degrees (OR, .07) in EUS-AG. The 1-year recurrence rate was 8.3% in both groups. CONCLUSIONS: Effectiveness and safety of BE-ERCP and EUS-AG were comparable in CBD stone removal for patients after R-Y gastrectomy, but complete stone removal after technical success was superior in BE-ERCP.

BACKGROUND AND AIMS: Post-ERCP pneumobilia is not uncommon; however, studies focusing on the long-term prognosis of patients with post-ERCP pneumobilia are limited. This study aimed to explore long-term prognosis and risk factors associated with post-ERCP pneumobilia in patients with common bile duct stones (CBDSs). METHODS: We conducted a retrospective analysis of 1380 patients who underwent ERCP for CBDSs at our hospital from January 2010 to December 2017. Patients were selected based on inclusion and exclusion criteria and divided into pneumobilia and nonpneumobilia groups, followed by propensity score matching. The matched groups were then compared in terms of incidence rates of both single and multiple recurrences of CBDSs, acute cholangitis, and acute cholecystitis. Multivariate logistic regression analysis was used to explore risk factors associated with pneumobilia. RESULTS: After propensity matching, there was no significant difference in the rate of single recurrence of CBDSs (22.5% vs 30%; P = .446) between the pneumobilia and nonpneumobilia groups. However, the incidences of multiple recurrences of CBDSs (32.5% vs 12.5%; P = .032) and acute cholangitis without stone recurrence (32.5% vs 2.5%; P = <.001) were significantly higher in the pneumobilia group. Based on multivariate logistic regression analysis, in addition to a dilated CBD (diameter of >1 cm) (odds ratio [OR], 2.48; 95% confidence interval [CI], 1.03-3.76; P = .043), endoscopic sphincterotomy with moderate incision (OR, 5.38; 95% CI, 1.14-25.47; P = .034) and with large incision (OR, 8.7; 95% CI, 1.83-41.46; P = .007) were identified as independent risk factors for pneumobilia after initial ERCP. CONCLUSIONS: Patients with post-ERCP pneumobilia have increased risk of multiple recurrences of CBDSs and acute cholangitis without stone recurrence. Independent risk factors for pneumobilia include peripapillary diverticulum, a dilated CBD (>1 cm), and endoscopic sphincterotomy with moderate and large incisions. A normal-sized CBD appears to serve as a secondary barrier against enterobiliary reflux, necessitating further research for confirmation.

PURPOSE: To evaluate the safety and effectiveness of percutaneous cholecystoenteric anastomosis (PCEA) creation in patients with indwelling cholecystostomy tubes who are high-risk surgical candidates. MATERIALS AND METHODS: Fourteen (male, 10; female, 4) patients with a mean age of 79 years (range, 53-92 years) with previously inserted cholecystostomy tubes underwent PCEA with the adjacent duodenum using a lumen-apposing metal stent (LAMS) between January 2015 and October 2022. Intraprocedural adverse events and postprocedural safety and effectiveness outcomes were evaluated. Nine procedures were performed under sedation and 5 under general anesthesia. RESULTS: Technical success was achieved in 100% of the patients. In 12 patients (86%), the existing cholecystostomy tube was removed after the insertion of the LAMS. Three patients (21%) had a pre-existing cholecystoduodenal fistula, in which the stent was placed, and 11 (79%) underwent creation of a de novo anastomosis. The mean procedure time was 1.5 hours (range, 1-2 hours). The mean length of stay after the procedure was 2.4 days (range, 1-10 days). There were no intraprocedural adverse events. One patient with severe pre-existing cardiac comorbidities died during his postprocedural stay despite a technically successful procedure. One patient had delayed closure of the long-standing cholecystocutaneous tract. CONCLUSIONS: Early clinical experience with PCEA using an LAMS suggests that it is a safe and effective option for the creation of internal gallbladder drainage in patients who are not candidates for surgical cholecystectomy.

BACKGROUND: The natural history of symptomatic uncomplicated gallstone disease is largely unknown. We examined the risk of progressing from symptomatic uncomplicated to complicated gallstone disease in a large regional cohort of patients, where disruptions in elective surgical capacities have led to the indefinite postponement of surgery for benign conditions, including cholecystectomies. METHODS: Patients with radiologically diagnosed incident symptomatic and uncomplicated gallstone disease were identified from outpatient clinics and emergency departments on the Island of Funen, Denmark. The absolute risk of complications (cholecystitis, cholangitis, pancreatitis, acute cholecystectomy for unremitting pain) was calculated using death and elective cholecystectomies as competing risks using the Aalen-Johansen method. Cox proportional hazards regression analysis was used to estimate hazard ratios (HRs) of gallstone complications associated with patient and gallstone characteristics. RESULTS: Two hundred eighty-six patients diagnosed with incident symptomatic, uncomplicated gallstone disease from 1 January 2020 to 1 July 2023 were identified. During 79,170 person-years of observation, 176 (61.5%) patients developed a gallstone-related complication. The 6-, 12- and 24-month risk of developing gallstone-related complications were 36%, 55% and 81%. The risk of developing complications related to common bile duct stones was lowest with larger stones (aHR per millimeter increase = 0.89 (0.82-0.97), p < 0.01), while no covariates were statistically significantly associated with the risk of cholecystitis. Eighty-five (30%) patients underwent elective laparoscopic cholecystectomy, with one patient (1.2%) developing a gallstone-related complication afterward. CONCLUSIONS: The risk of developing complications to symptomatic gallstones in a general Scandinavian population is high, and prophylactic cholecystectomy should be considered.

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

INTRODUCTION: Pancreaticobiliary reflux (PBR) can induce gallstone formation; however, its pathogenic mechanism remains unclear. In this study, we explored the mechanism of PBR by the non-targeted metabolomic analysis of bile in patients with PBR. OBJECTIVE: The aim of this study was to investigate the pathogenic mechanism in PBR by the non-targeted metabolomic analysis of bile collected during surgery. METHODS: Sixty patients who underwent gallstone surgery at our center from December 2020 to May 2021 were enrolled in the study. According to the level of bile amylase, 30 patients with increased bile amylase ( > 110 U/L) were classified into the PBR group, and the remaining 30 patients were classified into the control group (≤ 110 U/L). The metabolomic analysis of bile was performed. RESULTS: The orthogonal projections to latent structure-discriminant analysis of liquid chromatography mass spectrometry showed significant differences in bile components between the PBR and control groups, and 40 metabolites were screened by variable importance for the projection value (VIP > 1). The levels of phosphatidylcholine (PC) and PC (20:3(8Z,11Z,14Z)/14:0) decreased significantly, whereas the levels of lysoPC (16:1(9z)/0:0), lysoPC (15:0), lysoPC (16:0), palmitic acid, arachidonic acid, leucine, methionine, L-tyrosine, and phenylalanine increased. CONCLUSIONS: Significant differences in bile metabolites were observed between the PBR and control groups. Changes in amino acids and lipid metabolites may be related to stone formation and mucosal inflammation.

INTRODUCTION: Evidence for the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) between a basket catheter and a balloon catheter for endoscopic common bile duct stone (CBDS) removal is lacking. This study aimed to compare ERCP outcomes using a basket catheter and a balloon catheter for endoscopic CBDS removal. METHODS: This multicenter retrospective study included 904 consecutive patients with native papilla who underwent endoscopic stone removal for CBDS ≤10 mm using a basket catheter and/or a balloon catheter at three institutions in Japan. ERCP outcomes between the basket and balloon groups were compared using inverse probability of treatment weighting (IPTW) method. RESULTS: ERCP-related adverse events occurred in 6.5% (29/449) and 7.7% (35/455) of patients in the basket and balloon groups, respectively (IPTW-adjusted p = 0.52). The incidences of post-ERCP pancreatitis, cholangitis, and perforation were similar in the basket and balloon groups (3.8% vs. 2.9%, 1.3% vs. 0.9%, and 0.7% vs. 0.7%, respectively). However, bleeding incidences were significantly higher in the balloon group than in the basket group (3.3% vs. 0.7%, IPTW-adjusted p = 0.012). Successful complete stone removal at one ERCP session using a single catheter was achieved in 17.8% (80/449) in the basket group and in 81.3% (370/455) in the balloon group (IPTW-adjusted p < 0.001). DISCUSSION: A balloon catheter is more likely to complete stone extraction for CBDS ≤10 mm with a single catheter at one endoscopic stone removal session. However, the risk for post-ERCP bleeding is higher in the balloon group than in the basket group.

BACKGROUND: Low-pressure pneumoperitoneum (LPP) is an attempt to improve laparoscopic surgery. Lower pressure causes lesser inflammation and better hemodynamics. There is a lack of literature comparing inflammatory markers in LPP with deep NMB to standard pressure pneumoperitoneum (SPP) with moderate NMB in laparoscopic cholecystectomy. METHODOLOGY: This was a single institutional prospective randomized control trial. Participants included all patients undergoing laparoscopic cholecystectomy for symptomatic gall stone disease. Participants were divided into 2 groups group A and B. Group A-Low-pressure group in which pneumoperitoneum pressure was kept low (8-10 mmHg) with deep Neuromuscular blockade (NMB) and Group B-Normal pressure group (12-14 mmHg) with moderate NMB. A convenience sample size of 80 with 40 in each group was selected. Lab investigations like CBC, LFT, RFT and serum IL-1, IL-6, IL-17, TNF alpha levels were measured at base line and 24 h after surgery and compared using appropriate statistical tests. Other parameters like length of hospital stay, post-operative pain score, conversion rate (low-pressure to standard pressure), and complications were also compared. RESULTS: Eighty participants were analysed with 40 in each group. Baseline characteristics and investigations were statistically similar. Difference (post-operative-pre-operative) of inflammatory markers were compared between both groups. Numerically there was a slightly higher rise in most of the inflammatory markers (TLC, ESR, CRP, IL-6, TNFα) in Group B compared to Group A but not statistically significant. Albumin showed significant fall (p < 0.001) in Group B compared to Group A. Post-operative pain was also significantly less (p < 0.001) in Group A compared to Group B at 6 h and 24 h. There were no differences in length of hospital stay and incidence of complications. There was no conversion from low-pressure to standard pressure. CONCLUSION: Laparoscopic cholecystectomy performed under low-pressure pneumoperitoneum with deep NMB may have lesser inflammation and lesser post-operative pain compared to standard pressure pneumoperitoneum with moderate NMB. Future studies with larger sample size need to be designed to support these findings.

BACKGROUND: Sigmoid gallstone ileus is a rare complication of cholelithiasis, accounting for 1-4% of all cases of large-bowel obstruction. This is a highly morbid, and often fatal, condition due to its challenging diagnosis and late presentation. CASE PRESENTATION: We report a case of a 90-year-old woman admitted to Emergency Department with abdominal pain and large-bowel obstruction due to a 6 cm gallstone lodged in a diverticulum of the proximal sigmoid colon as a consequence of a cholecysto-colonic fistula. Colonoscopy was deferred due to gallstone size carrying a high possibility of failure. The patient underwent urgent laparotomy with gallstone removal via colotomy. The cholecystocolonic fistula was left untreated. The post-operative course was uneventful; the patient was discharged on 6th post-operative day. CONCLUSION: A multidisciplinary discussion between endoscopists and surgeons is often needed to choose the best therapeutic option, especially in high-risk patients.

BACKGROUND: In the event of symptomatic common bile duct (CBD) stones with dilated CBD, one possible curative treatment option is stone extraction through choledocotomy associated with cholecystectomy. Endoscopic treatment is only reserved for residual stones at 6 weeks. The aim of this study was to evaluate the results from laparoscopic curative surgical treatment of CBD stones with dilated CBD. METHODS: This is a retrospective single-centered cohort study. All consecutive patients admitted for laparoscopic cholecystectomy with evidence of CBD stones with dilated CBD from January 2010 to December 2020 at our center were included. Success was defined by CBD clearance at 6 weeks. Need for additional procedures, such as endoscopic sphincterotomy, immediate, and end-of-procedure morbi-mortality as well as factors associated with procedure failure, were also studied. RESULTS: A total of 246 patients who received curative treatment were included in the study. The success rate for the curative treatment was 93.1% (229 patients). Immediate postoperative morbidity was 24.4% with a 5.3% reintervention rate. Immediate and 6-week postoperative mortality rates were zero and 0.4%, respectively. The mean length of stay was 11.3 days. Factors associated with procedure failure appeared to be the occurrence of an early postoperative complication and the need for readmission during the period between surgery and drain removal. CONCLUSION: This study indicates that laparoscopic curative surgical treatment for symptomatic CBD stones may be performed with acceptable results without routine need for additional procedures.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the standard of care for symptomatic gall stone disease. A good scoring system is necessary to standardize the reporting. Our aim was to develop and validate an objective scoring system, the Surgical Cholecystectomy Score (SCS) to grade the difficulty of LC. METHODS: The study was conducted in a single surgical unit at a tertiary care hospital in two phases from January 2017 to April 2021. Retrospective data was analysed and the difficulty of each procedure was graded according to the modified Nassar's scoring system. Significant preoperative and intraoperative data obtained was given a weightage score. In phase II, these scores were validated on a prospective cohort. Each procedure was classified either as easy, moderately difficult or difficult. STATISTICAL ANALYSIS: A univariate analysis was performed on the data followed by a multivariate regression analysis. Bidirectional stepwise selection was done to select the most significant variables. The Beta /Schneeweiss scoring system was used to generate a rounded risk score. RESULTS: Data of 800 patients was retrieved and graded. 10 intraoperative parameters were found to be significant. Each variable was assigned a rounded risk score. The final SCS range for intraoperative parameters was 0-15. The scoring system was validated on a cohort of 249 LC. In the final scoring, cut off SCS of > 8 was found to correlate with difficult procedures. Score of < 2 was equivalent to easy LC. A score between 2 and 8 indicated moderate difficulty. The area under ROC curve was 0.98 and 0.92 for the intraoperative score indicating that the score was an excellent measure of the difficulty level of LCs. CONCLUSION: The scoring system developed in this study has shown an excellent correlation with the difficulty of LC. It needs to be validated in different cohorts and across multiple centers further.

INTRODUCTION: The management of CBDS (common bile duct stones) in patients with co-existing gallbladder stones has been debated. Guidelines recommend patients with CBDS identified on imaging should be offered duct clearance; however, this is based on low-quality evidence. This study aimed to investigate the natural history of small CBDS identified using IOUS (intraoperative ultrasound) in patients undergoing cholecystectomy. This may provide evidence to support a short-term expectant management approach in such patients. METHODS: Patients with CBDS diagnosed on IOUS during cholecystectomy were identified from a database of consecutive patients undergoing surgery. Patients with CBDS identified were divided into small stone (SS, ≤5 mm) and large stone (LS, >5 mm) groups. Intraoperative CBDS management, postoperative investigations, postoperative bile duct clearance, re-admissions, complications, length of stay (LOS) and follow-up are described. RESULTS: Fifty-nine of 427 patients had CBDS identified on IOUS. In the SS group (n=51), 46 patients underwent short-term expectant management rather than immediate/planned bile duct clearance. Following short-term expectant management, 41/46 patients (89.1%) did not require postoperative endoscopic retrograde cholangiopancreatography and at >3 year follow-up, none has since presented with residual CBDS. Median LOS was 0 days in the short-term expectant management group and 2 days in the immediate/planned bile duct clearance group, P=0.039. CONCLUSIONS: This study reports the natural history of small CBDS identified on IOUS in patients undergoing cholecystectomy. Such patients were safely treated with short-term expectant management associated with a reduced hospital LOS. This provides rationale for undertaking further research to establish this as a preferred management strategy.

PURPOSE: Gallstone formation is increased after gastric (GR) or esophageal resection (ER); however, the exact pathophysiology is not fully understood yet. Symptomatic cholecystolithiasis and the need for subsequent cholecystectomy after upper gastrointestinal resection can alter the outcome in oncological patients. There is an ongoing discussion if these patients benefit from a simultaneous prophylactic cholecystectomy. This study aims to analyze the risk of gallstone formation after GR or ER and the perioperative course of a subsequent cholecystectomy. METHODS: In this study, all patients were included, who underwent an oncological gastric or esophageal resection at the Medical University of Innsbruck, Department of Visceral, Transplant and Thoracic Surgery in the years 2003-2021. RESULTS: A simultaneous cholecystectomy was performed in 29.8% with GR and in 2.1% with ER (p < 0.001). There was no significant difference in complications or length-of-stay between patients with simultaneous vs. no simultaneous cholecystectomy. Newly developed gallstones tended to be more common after GR (16% vs. 10% ER), after reconstruction without preservation of the duodenal passage (17% vs. 11% with) and after GR with lymph node dissection (19% vs. 5% without). After ER, subsequent cholecystectomy was significant less frequently (11.4% vs. 2.9% OR) (p = 0.005). The subsequent cholecystectomy was performed openly in 57.1% with major complications classified as Clavien-Dindo ≥ 3a in 14.3%. CONCLUSION: Based on the findings of our study, we do not recommend simultaneous cholecystectomy routinely in oncological gastric or esophageal resections. An individualized approach depending on risk factors like extensive lymphadenectomy or duodenal passage can be discussed.

PURPOSE: This study aims to evaluate the efficacy of admission contrast-enhanced CT scans in formulating strategies for performing early laparoscopic cholecystectomy in cases of acute gallstone pancreatitis. METHODS: Patients diagnosed with acute gallstone pancreatitis underwent a CT scan upon admission (after at least 24 h from symptom onset) to confirm diagnosis and assess peripancreatic fluid, collections, gallstones, and common bile duct stones. Patients with mild acute gallstone pancreatitis, following the Atlanta classification and Baltazar score A or B, were identified as candidates for early cholecystectomy (within 72 h of admission). RESULTS: Within the analyzed period, 272 patients were diagnosed with mild acute gallstone pancreatitis according to the Atlanta Guidelines. A total of 33 patients (12.1%) were excluded: 17 (6.25%) due to SIRS, 10 (3.6%) due to local complications identified in CT (Balthazar D/E), and 6 (2.2%) due to severe comorbidities. Enhanced CT scans accurately detected gallstones, common bile duct stones, pancreatic enlargement, inflammation, pancreatic collections, and peripancreatic fluid. Among the cohort, 239 patients were selected for early laparoscopic cholecystectomy. Routine intraoperative cholangiogram was conducted in all cases, and where choledocholithiasis was present, successful treatment occurred through common bile duct exploration. Only one case required conversion from laparoscopic to open surgery. There were no observed severe complications or mortality. CONCLUSION: Admission CT scans are instrumental in identifying clinically stable patients with local tomographic complications that contraindicate early surgery. Patients meeting the criteria for mild acute gallstone pancreatitis, as per Atlanta guidelines, without SIRS or local complications (Baltazar D/E), can safely undergo early cholecystectomy within the initial 72 h of admission.

INTRODUCTION: Cholelithiasis is one of the most common diseases encountered in gastroenterology. Laparoscopic cholecystectomy can be labelled as difficult if the surgery continues for more than 60 minutes or if the cystic artery is injured before ligation or clipping. Predicting difficult laparoscopic cholecystectomy can help the surgeon to be prepared for intraoperative challenges such as adhesions in triangle of Calot, injury to cystic artery or gall stone spillage; and improve patient counseling. METHODS: In this cross-sectional study, we evaluated 269 patients with diagnosed cholelithiasis and planned for laparoscopic cholecystectomy in the general surgery department of Civil Hospital Karachi. After approval of the institution review board of the Civil Hospital, the data of all the patients was collected along with informed consent. The patients were selected via nonprobability, consecutive sampling. RESULTS: The prevalence of difficult LC during procedure was 14.5% (39/269). Contingency table showed the true positive, negative and false positive and negative observation and using these observation to compute accuracy. Sensitivity, specificity, PPV, NPV and accuracy of serum c-reactive protein (CRP) in predicting the difficult laparoscopic cholecystectomy in patients of cholelithiasis was 87.2%, 97%, 82.9%, 97.8% and 95.5% respectively. Effect modifiers like age, gender and BMI were controlled by stratification analysis and observed that diagnostic accuracy was above 90% in all stratified groups as presented in the following tables. 175 (65.06%) of 279 patients were females indicating female predominance. In general, 41 patients (15.05%) had CRP serum levels greater than 11 mg/dL out of which 34 patients had to undergo difficult laparoscopic cholecystectomy (DLC), while 223 out of 228 patients with serum CRP levels of less than 11 mg/dL did not face any difficulty during their cholecystectomy. Similar results have been acquired across all age groups and both genders. CONCLUSION: C Reactive Protein is a potent predictor of difficult laparoscopic cholecystectomy and its conversion preoperatively. Patients with preoperatively high C Reactive Protein CRP levels in serum have more chances of complication intraoperatively and increased chances of conversion from laparoscopic to open surgery. Preoperative C Reactive Protein (CRP) with values >11 mg/dL was associated with the highest odds of presenting difficult laparoscopic cholecystectomy (DLC) in our study. This value possesses good sensitivity, specificity, PPV, and NPV for predicting DLC in our population.

Removal of common bile duct stones in patients with a previous cholecystectomy was one of the first indications for ERCP with biliary sphincterotomy. Thanks to a minimally invasive procedure, patients were prevented from having a new operation. Subsequently, as the technique proved to be successful, ERCP was extended to all patients with choledocholithiasis, regardless of whether or not they had gallbladder. Also contributing was the fact that, at least in the beginnings, surgical interventions on the bile duct with laparoscopic cholecystectomy were more difficult. Nowadays, many surgeons prefer to perform cholecystectomy with a bile duct clean of stones. In this issue of the Spanish Journal of Gastroenterology, Gardenyes et al. present a study on ERCP for common bile duct stones in elderly patients. The novelty of this study is not only to analyze the ERCP procedure, which we already knew has similar success and complication rates to younger patients, but also to focus on the long-term outcome, considering the frailty that frequently accompanies aging. The study concludes that older patients may benefit from enhanced care protocols to reduce medical adverse events and improve outcomes. For us gastroenterologists and endoscopists, another conclusion that can be drawn from this study is that we should not be satisfied that ERCP in older patients has the same success and complication rates as in younger patients, but rather we should strive to ensure that the results are even better.

BACKGROUND: Laparoscopic cholecystectomy is the most common minimally invasive abdominal surgery procedure performed in Western countries; it offers several advantages over laparotomy but still carries some risks, such as intraoperative spillage of bile and gallstones. Diagnosis of dropped gallstones could be challenging, it is frequently delayed, and this can lead to further complications such as abscesses formation. METHODS: We report the history of a 51-year-old male with persistent dull abdominal pain in association to appetite loss, vomiting episodes and changes in regular bowel habits, a past medical history of laparoscopic cholecystectomy for biliary lithiasis (1.5 years earlier) and minimum elevation of inflammatory markers and gamma-GT values. RESULTS: Ultrasound examination showed perihepatic stones and magnetic resonance imaging revealed the presence of multiple perihepatic abscesses, findings compatible with fibrotic-inflammatory phenomena from 'dropped gallstones'. A re-laparoscopy was then performed with an abscess collection containing multiple gallstones; a liver wedge resection was also required due to strong adhesions. At follow up, the patient had improved both on clinical and biochemical perspective. CONCLUSION: Dropped gallstones are an underreported cause of morbidity and diagnostic dilemmas in subjects who underwent to laparoscopic cholecystectomy, in relation to infectious complications that can occur even several months or years after surgery. Imaging represents a valuable aid in the correct non-invasive diagnostic process, but proper awareness of this insidious condition is necessary. Surgeons and radiologists should always consider this eventuality in the differential diagnosis of a patient presenting with abdominal abscesses and history of cholecystectomy.

Necrotizi ng fasciit is [NF] i s a m ultifaceted disease of the muscle fascia and body tissues which demands the earliest intervention. Past reviews have documented ver y few cases of Aeromonas Hydroph ila [AH] induced N F fol lo wing abdominal surgery. AH can cause fatal NF as seen in a 72 year old female patient reported at Liaquat National Hospital &Medical College; a ter tiary care center in Karachi, Pakistan on 2nd April, 2022. She had a k nown comorbidity of hypertension and presented with the chief complaint of symptomatic gallstones for which she unde rwent Laparoscopic Cholecystectomy (LAPCHOL). She developed NF of the lower ab domen post- oper atively. Following uneventful Laparoscopic Cholecystectomy our pati ent presented to the ER two days later with severe lower abdo minal pain and overlyi ng celluliti s. Fasc io to my revealed extensive myonecrosis with necrotizing soft tissue in fe ction. Despite u ndergoing extensive surgical debr idement and broad spectr um antibi ot ic administration; the patient died in the ICU on the fifth postoperat ive day followi ng septic complications. Histopathologica l an alysis, confirmed i nflammat ion and necrosis. Culture sensitivity of the debrided tissue revealed AH. Approach should lie towards analyzing the behaviour of such microbes in high risk patients through collective case studies. This is the first clinical case showcasing such parameters e ncountered in the General Surger y Department.
