cholecystectomy

摘要： Background: Spontaneous gallbladder perforation(GBP) is an uncommon diagnosis. This study presented the experience of managing spontaneous GBP over nine years at a large, tertiary care university hospital in north India and investigated the outcomes and treatment strategies. Methods: A retrospective review of prospectively maintained digital database of consecutive patients was performed. All patients received medical and/or surgical treatment for spontaneous GBP in our department between January 2010 and June 2018. Results: We identifed 151 patients(81 females and 70 males) with mean age of 53 years. Most common presenting features were pain(96.7%), fever(54.3%) and jaundice(31.1%). Most common cause was gallbladder stones(84.8%) followed by common bile duct stones(30.5%), xanthogranulomatous cholecystitis(17.9%) and malignancy(11.9%). As per Niemeier classifcation, 8.6% had type 1 GBP(free perforation in peritoneal cavity), 76.2% had type 2 GBP(localized perforation) and 13.2% had type 3 GBP(cholecystoenteric fstula). About 60% of the perforations were diagnosed preoperatively. Type 1 was more common in patients with diabetes and also had the worst prognosis. Surgery was performed in 109 patients(72.2%). Seven patients(4.6%) had a postoperative morbidity of Clavien-Dindo Ⅲ or higher. There were three mortalities in patients who underwent surgery. Conclusions: High index of suspicion is required for preoperative diagnosis of GBP, especially in types 2 and 3. Laparoscopic cholecystectomy can be difficult in these patients and patients may require open or partial cholecystectomy. Early diagnosis and step-up approach for the treatment of GBP is critical.

摘要： BACKGROUND Gallbladder perforation and gastrointestinal fistula are rare but serious complications of severe acute pancreatitis(SAP).However,neither spontaneous gallbladder perforation nor cholecysto-colonic fistula has been reported in acalculous acute pancreatitis patients.CASE SUMMARY A 31-year-old male presenting with epigastric pain was diagnosed with hypertriglyceridemia-related SAP.He suffered from multiorgan failure and was able to leave the intensive care unit on day 20.Three percutaneous drainage tubes were placed for profound exudation in the peripancreatic region and left paracolic sulcus.He developed spontaneous gallbladder perforation with symptoms of fever and right upper quadrant pain 1 mo after SAP onset and was stabilized by percutaneous drainage.Peripancreatic infection appeared 1 mo later and was treated with antibiotics but without satisfactory results.Then multiple colon fistulas,including a cholecysto-colonic fistula and a descending colon fistula,emerged 3 mo after the onset of SAP.Nephroscopy-assisted peripancreatic debridement and ileostomy were carried out immediately.The fistulas achieved spontaneous closure 7 mo later,and the patient recovered after cholecystectomy and ileostomy reduction.We presume that the causes of gallbladder perforation are poor bile drainage due to external pressure,pancreatic enzyme erosion,and ischemia.The possible causes of colon fistulas are pancreatic enzymes or infected necrosis erosion,ischemia,and iatrogenic injury.According to our experience,localized gallbladder perforation can be stabilized by percutaneous drainage.Pancreatic debridement and proximal colostomy followed by cholecystectomy are feasible and valid treatment options for cholecysto-colonic fistulas.CONCLUSION Gallbladder perforation and cholecysto-colonic fistula should be considered in acalculous SAP patients.

摘要： Background: There are few randomized controlled trials with sufficient statistical power to assess the effectiveness of intraoperative cholangiography(IOC) in the detection and treatment of common bile duct injury(BDI) or retained stones during cholecystectomy. The best evidence so far regarding IOC and reduced morbidity related to BDI and retained common bile duct stones was derived from large populationbased cohort studies. Population-based studies also have the advantage of reflecting the outcome of the procedure as it is practiced in the community at large. However, the outcomes of these population-based studies are conflicting. Data sources: A systematic literature search was conducted in 2020 to search for articles that contained the terms “bile duct injury”, “critical view of safety”, “bile duct imaging” or “retained stones” in combination with IOC. All identifed references were screened to select population-based studies and observational studies from large centers where socioeconomic or geographical selections were assumed not to cause selection bias. Results: The search revealed 273 references. A total of 30 articles fulflled the criteria for a large observational study with minimal risk for selection bias. The majority suggested that IOC reduces morbidity associated with BDI and retained common bile duct stones. In the short term, IOC increases the cost of surgery. However, this is offset by reduced costs in the long run since BDI or retained stones detected during surgery are managed immediately. Conclusions: IOC reduces morbidity associated with BDI and retained common bile duct stones. The reports reviewed are derived from large, unselected populations, thereby providing a high external validity. However, more studies on routine and selective IOC with well-defned outcome measures and sufficient statistical power are needed.

摘要： Background:Acute calculous cholecystitis(ACC)is frequently seen in cirrhotics,with some being poor candidates for initial cholecystectomy.Instead,these patients may undergo percutaneous cholecystostomy tube(PCT)placement.We studied the healthcare utilization and predictors of cholecystectomy and PCT in patients with ACC.Methods:The National Database was queried to study all cirrhotics and non-cirrhotics with ACC between 2010-2014 who underwent initial PCT(with or without follow-up cholecystectomy)or cholecystectomy.Cirrhotic patients were divided into compensated and decompensated cirrhosis.Independent predictors and outcomes of initial PCT and failure to undergo subsequent cholecystectomy were studied.Results:Out of 919189 patients with ACC,13283(1.4%)had cirrhosis.Among cirrhotics,cholecystec-tomy was performed in 12790(96.3%)and PCT in the remaining 493(3.7%).PCT was more frequent in cirrhotics(3.7%)than in non-cirrhotics(1.4%).Multivariate analyses showed increased early readmis-sions[odds ratio(OR)=2.12,95%confidence interval(CI):1.43-3.13,P<0.001],length of stay(effect ratio=1.39,95%CI:1.20-1.61,P<0.001),calendar-year hospital cost(effect ratio=1.34,95%CI:1.28-1.39,P<0.001)and calendar-year mortality(hazard ratio=1.89,95%CI:1.07-3.29,P=0.030)in cir-rhotics undergoing initial PCT compared to cholecystectomy.Decompensated cirrhosis(OR=2.25,95%CI:1.67-3.03,P<0.001)had the highest odds of getting initial PCT.Cirrhosis,regardless of compensated(OR=0.56,95%CI:0.34-0.90,P=0.020)or decompensated(OR=0.28,95%CI:0.14-0.59,P<0.001),reduced the chances of getting a subsequent cholecystectomy.Conclusions:Cirrhotic patients undergo fewer cholecystectomy incurring initial PCT instead.Moreover,the rates of follow-up cholecystectomy are lower in cirrhotics.Increased healthcare utilization is seen with initial PCT amongst cirrhotic patients.This situation reflects suboptimal management of ACC in cirrhotics and a call for action.

摘要： Background: Cholecystectomy is considered a general surgical operation. However, general surgeons are not trained to manage severe complications such as bile duct injury(BDI) and should refer to hepatopancreatobiliary(HPB) surgeons when difficulty arises. This study aimed to investigate the outcomes of patients who had on-table HPB consults during cholecystectomy. Methods: This is an audit of 50 patients who required on-table HPB consult during cholecystectomy from 2011 to 2017. Consultations were classified as “proactive” and “reactive”, where consults were made before or after surgical incision, respectively. Patient demographics and perioperative details were collected. Results: The median age of the patients was 62.5 years [interquartile range(IQR) 50.8–71.3 years]. Eight(16%) patients had underlying HPB co-morbidity. Gallbladder wall was thickened in all patients(median 5 mm, IQR 4–7 mm), and common bile duct was of normal caliber in all patients(median 5 mm, IQR 4–6 mm). Median length of operation and length of stay were 165 min(IQR 124–209 min) and five days(IQR 3–7 days), respectively. Subtotal cholecystectomy was performed in 18(36%) patients. Forty-eight patients were initially managed by laparoscopic approach, 15(31%) required open conversion;majority(9/15, 60%) were initiated before on-table consult. Majority of referrals(98%) were reactive. Common reasons for referral included unclear anatomy or anatomical variations(30%), presence of dense adhesions and/or contracted gallbladder(18%) and impacted stones in Hartmann’s pouch(16%). Three(6%) patients were referred for BDI(2 Strasberg D and 1 Strasberg E1), and two(4%) were referred for torrential bleeding from arterial injury(1 cystic artery and 1 right hepatic artery). Any morbidity and 30-day readmission were 22% and 6%, respectively. There was no 90-day mortality. Conclusions: Calling for help in BDI is obligatory, but in other instances is a personal choice. Calling for help prior to open conversion is lacking and this awareness should be raised. Whether surgical outcomes could be improved by early HPB consult needs to be determined by larger multicenter reports.

摘要： Objective: The treatment of iatrogenic bile duct injuries is still a challenge for hepatobiliary and general surgeons. Roux-en-Y hepaticojejunostomy, one of the most appropriate techniques for the treatment of circumferential lesions, either occurring less than 2 cm from the bifurcation or in the bifurcation of the common hepatic duct, requires experience in advanced laparoscopy and hepatobiliary surgery. This study aims to present the results of laparoscopic hepaticojejunostomy (LHJ) for the treatment of iatrogenic bile duct injuries (IBDI). Methods: A retrospective study analyzing the medical records of patients diagnosed with IBDI and treated using LHJ of patients at the Hospital S?o José do Avaí (HSJA). Sex, age, previous cholecystectomy technique, signs and symptoms, postoperative complications, length of stay, injury classification, and time elapsed from injury to diagnosis were analyzed. Magnetic resonance cholangiography (MRC), endoscopic retrograde cholangiopancreatography (ERCP) or intraoperative cholangiography. Results: From March 2006 to December 2018, six patients underwent LHJ. In five cases (83.33%), the primary operation was a laparoscopic cholecystectomy (LC) and in one patient (13.66%) open cholecystectomy. The most frequent clinical sign was jaundice. The mean surgical time was 153.2 minutes (range: 115 to 206 minutes), and the hospital stay was 3 to 7 days (mean: 4.16 days). One patient had infection of the umbilical trocar incision and one patient presented with stenosis of the hepaticojejunal anastomosis and was treated with radioscopic pneumatic dilatation. Conclusion: LHJ for circumferential and total IBDI either diagnosed early (during surgery) or late, may be a safe and effective option, with similar results to the conventional technique, a low complication rate and all the known advantages of minimally invasive surgery.

摘要： BACKGROUND Gallbladder hemorrhage is a life-threatening disorder.Trauma(accidental or iatrogenic such as a percutaneous biopsy or cholecystectomy surgery),cholelithiasis,biliary tract parasitosis,vasculitis,vascular malformations,autoimmune and neoplastic diseases and coagulopathies have been described as causes of hemorrhage within the lumen of the gallbladder.The use of nonsteroidal anti-inflammatory drugs and anticoagulants may represent a risk factor.CASE SUMMARY We report the case of a 76-year-old male patient.An urgent contrast computed tomography scan demonstrated relevant distension of the gallbladder filled with hyperdense non-homogeneous content.The gallbladder walls were of regular thickness.Near the anterior wall a focus of suspected active bleeding was observed.Due to the progressive decrease in hemoglobin despite three blood transfusions,this was an indication for urgent surgery.CONCLUSION Early diagnosis of this potentially fatal pathology is essential in order to plan a strategy and eventually proceed with urgent surgical treatment.

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