Textbook outcome in urgent early cholecystectomy for acute calculous cholecystitis: results post hoc of the S.P.Ri.M.A.C.C study.

INTRODUCTION: A textbook outcome patient is one in which the operative course passes uneventful, without complications, readmission or mortality. There is a lack of publications in terms of TO on acute cholecystitis. OBJETIVE: The objective of this study is to analyze the achievement of TO in patients with urgent early cholecystectomy (UEC) for Acute Cholecystitis. and to identify which factors are related to achieving TO. MATERIALS AND METHODS: This is a post hoc study of the SPRiMACC study. It´s a prospective multicenter observational study run by WSES. The criteria to define TO in urgent early cholecystectomy (TOUEC) were no 30-day mortality, no 30-day postoperative complications, no readmission within 30 days, and hospital stay ≤ 7 days (75th percentile), and full laparoscopic surgery. Patients who met all these conditions were taken as presenting a TOUEC. OUTCOMES: 1246 urgent early cholecystectomies for ACC were included. In all, 789 patients (63.3%) achieved all TOUEC parameters, while 457 (36.6%) failed to achieve one or more parameters and were considered non-TOUEC. The patients who achieved TOUEC were younger had significantly lower scores on all the risk scales analyzed. In the serological tests, TOUEC patients had lower values for in a lot of variables than non-TOUEC patients. The TOUEC group had lower rates of complicated cholecystitis. Considering operative time, a shorter duration was also associated with a higher probability of reaching TOUEC. CONCLUSION: Knowledge of the factors that influence the TOUEC can allow us to improve our results in terms of textbook outcome.

Laparoscopic subtotal cholecystectomy for the difficult gallbladder: Evolution of technique at a single teaching hospital.

BACKGROUND: We have developed an algorithmic approach to laparoscopic cholecystectomy, including subtotal cholecystectomy, as a bailout strategy when the Critical View of Safety cannot be safely achieved due to significant inflammation and fibrosis of the hepatocystic triangle. METHODS: This is a retrospective cohort study comparing postoperative outcomes in patients with severe cholecystitis who underwent laparoscopic cholecystectomy or laparoscopic subtotal cholecystectomy at St. Joseph's Health Centre from May 2016 to July 2021, as well as against a historical cohort. We further stratified laparoscopic subtotal cholecystectomy cases based on fenestrating or reconstituting subtype. RESULTS: The cohort included a total of 105 patients who underwent laparoscopic cholecystectomy and 31 patients who underwent laparoscopic subtotal cholecystectomy. Bile leaks (25.8% vs 1.0%, relative risk 3.5, 95% confidence interval 3.5-208.4) were more common in the laparoscopic subtotal cholecystectomy group. Postoperative endoscopic retrograde cholangiopancreatography (22.6% vs 3.8%, relative risk 5.9, 95% confidence interval 1.9-18.9) and biliary stent insertion (19.4% vs 1.0%, relative risk 20.3, 95% confidence interval 2.5-162.5) were also more common in the laparoscopic subtotal cholecystectomy group. Bile leaks in laparoscopic subtotal cholecystectomy were only documented in the fenestration subtype, most of which were successfully managed with endoscopic retrograde cholangiopancreatography and biliary stenting. Compared to our previous study of laparoscopic cholecystectomy and subtotal cholecystectomy for severe cholecystitis between 2010 and 2016, there has been a decrease in postoperative laparoscopic cholecystectomy complications, subtotal cholecystectomy cases, and no bile duct injuries. CONCLUSION: Following our algorithmic approach to safe laparoscopic cholecystectomy has helped to prevent bile duct injury. Laparoscopic cholecystectomy remains the gold standard for the management of severe cholecystitis; however, in extreme cases, laparoscopic subtotal cholecystectomy is a safe bailout strategy with manageable morbidity.

Early Cholecystectomy in Patients with Sickle Cell Disease with Uncomplicated Cholelithiasis Is Associated with Better Outcomes.

BACKGROUND: Up to 85% of patients with sickle cell disease (SCD) will develop gallstones by their third decade. Cholecystectomy is the most commonly performed procedure in these patients. Cholecystectomy is recommended for patients with SCD with symptomatic cholelithiasis and leads to lower morbidity. No contemporary large studies have evaluated this recommendation or associated clinical outcomes. This study evaluates clinical outcomes after cholecystectomy in patients with SCD and cholelithiasis with specific advanced clinical presentations. STUDY DESIGN: The Nationwide Inpatient Sample was queried for patients with SCD and gallbladder disease between 2006 and 2015. Patients were divided into groups based on their disease presentation, including uncomplicated cholelithiasis, acute and chronic cholecystitis, and gallstone pancreatitis. Clinical outcomes associated with disease presentation were analyzed. Statistical analysis was performed using the Student's t -test, chi-square test, ANOVA, and logistic regression. RESULTS: There were 6,662 patients with SCD who presented with cholelithiasis. Median age was 20 (interquartile range 16 to 34) years and 54% were female patients. Cholecystectomy was performed in 1,779 patients with SCD with the most common indication being chronic cholecystitis (44%), followed by uncomplicated cholelithiasis (27%), acute cholecystitis (21%), and choledocholithiasis or gallstone pancreatitis (8%). On multivariable regression, advanced clinical presentation was the strongest predictor of perioperative vaso-occlusive crisis, which was the most common complication. Patients undergoing cholecystectomy for uncomplicated cholelithiasis were at lower risk than those with acute cholecystitis (odds ratio [OR] 2.37; 95% CI 1.64 to 3.41), chronic cholecystitis (OR 1.74; 95% CI 1.26 to 2.4), and choledocholithiasis or gallstone pancreatitis (OR 2.24; 95% CI 1.41 to 3.57). CONCLUSIONS: Seventy-three percent of patients with SCD have advanced clinical presentation at the time of their cholecystectomy. After cholecystectomy, perioperative vaso-occlusive events were significantly increased in patients with advanced clinical presentation. These data support screening abdominal ultrasounds and early cholecystectomy for cholelithiasis in patients with SCD.

Subtotal vs total cholecystectomy for difficult gallbladders: A systematic review and meta-analysis.

INTRODUCTION: With severely inflamed gallbladders, laparoscopic cholecystectomy can be difficult and may require procedures like subtotal cholecystectomy (SC). Few studies exist comparing SC and total cholecystectomy (TC) in the setting of severe biliary inflammation. This meta-analysis aims to compare SC and TC for difficult gallbladders. METHODS: Medline-OVID, Embase-OVID, and Cinahl were searched including only studies comparing SC to TC for difficult gallbladders. Primary outcome was CBD injury. Secondary outcomes included bile leak, duodenal injury, retained stone, bleeding, intraabdominal collection, wound infection, reoperation, and mortality. RESULTS: Ten studies were included. Compared to TC, SC significantly lowered the risk for CBD injury (0 â€‹% vs. 1.6 â€‹%, RR 0.30, 95%CI 0.10-0.87) but increased risk of bile leaks (RR 3.5, 95%CI 1.79-6.84), postoperative ERCP (RR 2.86, 95%CI 1.53-5.35), intraabdominal collections (RR 2.55, 95%CI 1.32-4.93), and reoperation (RR 2.92, 95%CI 1.14-7.47). CONCLUSION: SC is a reasonable alternative to difficult gallbladders that may decrease the risk of CBD injuries. Knowing both approaches is crucial to manage the difficult gallbladder while minimizing harm. Further studies are needed to understand the value of SC for difficult cholecystectomy.

Evaluating Clinical Outcomes of Laparoscopic Subtotal and Total Cholecystectomy for Complicated Acute Cholecystitis: A Systematic Review and Meta-Analysis.

INTRODUCTION: This systematic review and meta-analysis aimed to compare clinical outcomes in patients with complicated acute cholecystitis undergoing laparoscopic total vs subtotal cholecystectomy. METHODS: This systematic review and meta-analysis was conducted according to PRISMA guidelines and queried PubMed, Embase, ProQuest, Google Scholar, and Cochrane databases from inception to May 2023. The primary outcome was complication rates including common bile duct injury, wound infection, reoperation, bile leak, retained stones, and subhepatic collection, whereas secondary outcomes were in-hospital mortality and hospital length of stay. RESULTS: A total of 7 studies with 135,233 cases were included for meta-analysis. Patients who underwent laparoscopic total cholecystectomy had a significantly lower risk of postoperative bile leaks (RR: .15; 95% CI: .03, .80) and subhepatic fluid collection (RR: 0.19; 95% CI: .06, .63) and were 2.94 times less likely to die compared to those who underwent subtotal cholecystectomy (RR .34; 95% CI: .15, .77). Patients who underwent subtotal cholecystectomy had significantly longer hospital length of stay (mean difference 1.0 days; 95% CI: .5 days, 1.4 days). CONCLUSIONS: In adult patients presenting with complicated cholecystitis, management with laparoscopic subtotal cholecystectomy presents a unique complication profile with increased risk of postoperative bile leak and subhepatic fluid collection, in-hospital mortality, and longer hospital length-of-stay when used as an alternative approach to laparoscopic total cholecystectomy. Further research into the most appropriate clinical scenarios and patient populations for the use of the subtotal cholecystectomy approach may prove useful in improving its associated outcomes.

Gallbladder strangulation caused by a fibrotic band due to chlamydia infection: A case report.

Acute cholecystitis, a very common disease, is usually caused by gallstone obstruction of the cystic duct. Meanwhile, strangulated cholecystitis is extremely rare, and it develops when the gallbladder is strangled by a band. It is very similar to gallbladder torsion in terms of imaging findings and obstruction of blood and biliary flow, and it requires emergency surgery. We herein report a case of a 90-year-old woman with gallbladder strangulation caused by a fibrotic band due to a chlamydia infection, and we also reviewed some literature on strangulated cholecystitis.

Current Operative Approaches to the Diseased Gallbladder. Diagnosis and Management Updates for General Surgeons.

Cholecystitis is a common diagnosis which requires management by general surgeons. Morbidity from cholecystitis is often life-threatening, especially in patients with underlying liver cirrhosis or other medical comorbidities. Diagnosis and management of this disease can vary among providers and hospitals. The decision to utilize a radiological or endoscopic temporizing maneuver in severe acute cholecystitis and the timing of later definitive cholecystectomy are relevant points of discussion within general surgery societies. In the last 5 years, the use of intraoperative ductal imaging by conventional vs fluorescence cholangiography had gained significant interest due to the widespread availability of indocyanine green. Finally, the operative strategies and how to manage intra-/postoperative complications are very important to optimizing patient outcomes. In this review paper, we discuss all treatment aspects of cholecystitis and provide updates in its management.

Distinguishing characteristics of xanthogranulomatous cholecystitis and gallbladder adenocarcinoma: a persistent diagnostic dilemma.

BACKGROUND: Xanthogranulomatous cholecystitis (XGC) is an uncommon variant of chronic cholecystitis which can resemble gallbladder adenocarcinoma (GAC) on preoperative imaging and present technical challenges in the performance of cholecystectomy. We examined our experience with each pathology to identify distinguishing characteristics that may guide patient counseling and surgical management. METHODS: A retrospective review of all pathologically confirmed cases of XGC and GAC following cholecystectomy between 2015 and 2021 at a single institution was performed. Clinical, biochemical, radiographic, and intraoperative features were compared. RESULTS: There were 37 cases of XGC and 20 cases of GAC. Patients with GAC were older (mean 70.3 years vs 58.0, p = 0.01) and exclusively female (100% vs 45.9%, p < 0.0001). There were no significant differences in accompanying symptoms between groups (nausea/vomiting, fevers, or jaundice). The mean maximum white blood cell count was elevated for XGC compared to GAC (16.4 vs 8.6 respectively, p = 0.044); however, there were no differences in the remainder of the biochemical profile, including bilirubin, liver transaminases, CEA, and CA 19-9. The presence of an intraluminal mass (61.1% vs 9.1%, p = 0.0001) and lymphadenopathy (18.8%. vs 0.0%, p = 0.045) were associated with malignancy, whereas gallbladder wall thickening as reported on imaging (87.9% vs 38.9%, p = 0.0008) and gallstones (76.5% vs. 50.0%, p = 0.053) were more often present with XGC. Cases of XGC more often had significant adhesions/inflammation (83.8% vs 55.0%, p = 0.03). CONCLUSION: Clinical features that may favor benign chronic cholecystitis over gallbladder adenocarcinoma include younger age, male gender, current or prior leukocytosis, and the absence of an intraluminal mass or lymphadenopathy. Laparoscopic cholecystectomy is a safe surgical option for equivocal presentations. Intraoperative frozen section or intentional staging of more extensive procedures based upon final histopathology are valuable surgical strategies.

Meta-analysis of fenestrating versus reconstituting subtotal cholecystectomy in the management of difficult gallbladder.

AIMS: To evaluate comparative outcomes of fenestrating and reconstituting subtotal cholecystectomy (STC) in patients with difficult gallbladder. METHODS: A systematic search of electronic data sources and bibliographic reference lists were conducted. All comparative studies reporting outcomes of laparoscopic fenestrating and reconstituting STC were included and their risk of bias were assessed using ROBINS-I tool. RESULTS: Seven comparative studies were included enrolling 590 patients undergoing laparoscopic STC using either fenestrating (n = 353) or reconstituting (n = 237) approaches. Although fenestrating STC was associated with a significantly higher rate of bile leak (OR: 2.47, p = 0.007) compared to reconstituting STC, both approaches were comparable in terms of resolution of bile leak without (RD: -0.02, p = 0.86) or with (OR: 1.84, p = 0.40) postoperative ERCP. Moreover, there was no significant difference in development of bile duct injury (RD: -0.02, p = 0.16), need for postoperative ERCP (OR: 1.36, p = 0.49), wound infection (RD: 0.03, p = 0.27), re-operation (OR: 0.95, p = 0.95), gallbladder remnant cholecystitis (OR: 0.21, p = 0.09) or need for completion cholecystectomy (RD: 0.01, p = 0.59) between two groups. CONCLUSIONS: Fenestrating STC is associated with a higher risk of bile leak than the reconstructing technique. This issue can be mitigated by routine use of drains, delayed drain removal, and in selected cases endoscopic therapy. We encourage the fenestrating approach considering trends in improved short- and long-term outcomes.

Percutaneous transhepatic gallbladder drainage versus endoscopic gallbladder stenting for managing acute cholecystitis until laparoscopic cholecystectomy.

INTRODUCTION: Gallbladder drainage by methods such as percutaneous transhepatic gallbladder drainage (PTGBD) or endoscopic gallbladder stenting (EGBS) is important in the early management of moderate to severe acute cholecystitis. METHODS: In patients undergoing laparoscopic cholecystectomy (LC) for acute cholecystitis after a month or more of gallbladder drainage, the clinical course was compared between patients initially treated with PTGBD or EGBS. RESULTS: Among 331 patients undergoing LC for cholecystitis between 2018 and 2022, 43 first underwent 1 or more months of gallbladder drainage. The median interval between drainage initiation and LC was 89 days (range, 28-261) among 34 patients with PTGBD and 70 days (range, 62-188) among nine with EGBS (p = 0.644). During this waiting period, PTGBD was clamped in six patients and removed in five. Cholecystitis relapsed in three PTGBD patients (9%) and four EGBS patients (44%; p = 0.026). Relapses were managed with medications. Cholecystectomy duration (p = 0.022), intraoperative blood loss (p = 0.026), frequency of abdominal drain insertion (p = 0.023), and resort to bailout surgery such as fundus-first approaches (p = 0.030) were significantly greater in patients with EGBS. Postoperative complications were somewhat likelier (p = 0.095) and postoperative hospital stays were longer (p = 0.007) in the EGBS group. CONCLUSION: Among patients whose LC was performed 1 or more months after initiation of drainage, daily living during the waiting period associated with drainage was well supported by EGBS, but LC and the postoperative course were more complicated than in PTGBD patients.

Adverse events of self-expandable metal stent placement for malignant distal biliary obstruction: a large multicenter study.

BACKGROUND AND AIMS: Endoscopic placement of self-expandable metal stents (SEMSs) for malignant distal biliary obstruction (MDBO) may be accompanied by several types of adverse events. The present study analyzed the adverse events occurring after SEMS placement for MDBO. METHODS: The present study retrospectively investigated the incidence and types of adverse events in patients who underwent SEMS placement for MDBO between April 2018 and March 2021 at 26 hospitals. Risk factors for acute pancreatitis, cholecystitis, and recurrent biliary obstruction (RBO) were evaluated by univariate and multivariate analyses. RESULTS: Of the 1425 patients implanted with SEMSs for MDBO, 228 (16.0%) and 393 (27.6%) experienced early adverse events and RBO, respectively. Pancreatic duct without tumor involvement (P = .023), intact papilla (P = .025), and SEMS placement across the papilla (P = .037) were independent risk factors for acute pancreatitis. Tumor involvement in the orifice of the cystic duct was an independent risk factor for cholecystitis (P < .001). Use of fully and partially covered SEMSs was an independent risk factor for food impaction and/or sludge. Use of fully covered SEMSs was an independent risk factor for stent migration. Use of uncovered SEMSs and laser-cut SEMSs was an independent risk factor for tumor ingrowth. CONCLUSIONS: Pancreatic duct without tumor involvement, intact papilla, and SEMS placement across the papilla were independent risk factors for acute pancreatitis, and tumor involvement in the orifice of the cystic duct was an independent risk factor for cholecystitis. The risk factors for food impaction and/or sludge, stent migration, and tumor ingrowth differed among types of SEMSs.

Referral practices are associated with a delay in treatment of symptomatic cholelithiasis and cholecystitis.

BACKGROUND: The project was performed to determine if referrals to non-surgical providers after an initial presentation of symptomatic cholelithiasis are associated with a delay in surgical management. METHODS: A single institution chart review of all adult patients who underwent a cholecystectomy from 2015 to 2019 was completed. Quantitative data was analyzed using independent t-tests. RESULTS: Of 574 reviewed, 482 patients met criteria. Following initial presentation, 295 (61.2%) received a referral to surgery and 187 (38.8%) received follow up with a non-surgical provider. Those in the latter group had a significantly longer time from initial symptom presentation to surgical evaluation (65.7 days vs. 10.3 days, p â€‹< â€‹0.001) and cholecystectomy (102.0 days vs 39.1 days, p â€‹< â€‹0.001) when compared to the surgery referral group. CONCLUSIONS: This study demonstrated that cholecystectomy was significantly delayed for patients who had been referred to non-surgical providers after initial presentation, prolonging symptoms and increasing use of healthcare resources.

Double cholecystectomy of duplex gallbladder associated with chronic cholecystitis in a cat.

A 6-year-old female neutered Persian cat presented with hyporexia and gradual weight loss over 6 months. Physical examination revealed cranial abdominal pain. Haematology and serum biochemistry were within normal limits. Abdominal ultrasonography and a computed tomography scan suggested a non-neoplastic mass compressing the gallbladder. During an exploratory laparotomy, a duplex gallbladder with two separate cystic ducts was diagnosed intraoperatively. The mass identified using the imaging techniques was an abnormal right gallbladder which was distended with immobile mucoid bile and a thickened wall. The left gallbladder and cystic duct were grossly normal. A cholecystectomy of both gallbladders was performed. Histopathology of the right gallbladder identified chronic cholecystitis. The cat made a good recovery from surgery and reported complete resolution of its hyporexia and a return to normal body weight. This is the first report of a successful cholecystectomy of a duplex gallbladder with chronic cholecystitis of a single gallbladder.

Does Operative Time Affect Complication Rate in Laparoscopic Cholecystectomy.

BACKGROUND: Laparoscopic cholecystectomy is the most common laparoscopic procedure performed in the United States. Our aim was to determine if increased operative time (OT) is associated with increased morbidity following laparoscopic cholecystectomy. METHODS: Using ACS NSQIP from 2006 to 2015, we identified all adult (≥18 years) patients that underwent laparoscopic cholecystectomy for cholecystitis performed within 3 days of admission. Our analysis was limited to cases with OT ≥15 minutes and ≤360 minutes. Outcome variables included postoperative surgical site infections (SSI), dehiscence, pneumonia, reintubation, failure to wean from ventilator, pulmonary embolism, renal failure, urinary tract infection, cardiac arrest, myocardial infarct, bleeding, deep vein thrombosis, sepsis, septic shock, return to the operating room, and death. RESULTS: 7,031 cases met inclusion criteria. Median OT was 63 minutes, first quartile was 46 minutes and third quartile was 87 minutes. Logistic regression analysis showed that increased OT (third vs first quartile) was an independent risk factor for superficial SSI (OR 1.75, 95% CI 1.36-2.25, P < .0001), organ-space SSI (OR 1.77, 95% CI 1.33-2.35, P < .0001), dehiscence (OR 2.03, 95% CI 1.01-4.07, P = 0.0470), and septic shock (OR 1.81, 95% CI 1.06-3.09, P = 0.0286). Increased OT was independently associated with increased LOS (fourth vs 1st quartile: IRR 1.53, P < 0.0001; third vs 1st quartile: IRR 1.29, P < .0001; 2nd vs 1st quartile: IRR 1.16, P < 0.0001). CONCLUSION: Increased OT is independently associated with morbidity and increased LOS following laparoscopic cholecystectomy for cholecystitis. Prospective studies are warranted to determine which factors contribute to increased OT and why.

Laparoscopic cholecystectomy assisted by combined intravenous and intracholecystic fluorescent cholangiography: a case report.

This case report describes a laparoscopic approach using fluorescence imaging guidance to treat gangrenous cholecystitis with perforation (GCP). A male patient in his early 60s presented with 3 days of right upper abdominal pain. Computed tomography and ultrasonography findings were consistent with a stone incarcerated in the gallbladder neck, GCP, and localized peritonitis. Percutaneous gallbladder drainage was initially performed, followed by laparoscopic cholecystectomy 7 days later, using combined intravenous and intracholecystic fluorescent cholangiography. This technique allowed visualization of the cystic and common bile ducts during surgery and enabled safe removal of the diseased gallbladder. The patient recovered well without complications, and reported no pain or discomfort at a 2-month follow-up.

Gallbladder stones during pregnancy: are we doing the right thing in Mexico?

OBJECTIVE: To present the treatment of choice and approach in pregnant and postpartum women with a diagnosis of gallstones in Mexico and to compare it with the recommendations of international guidelines. METHOD: Observational, descriptive, and retrospective study based on information from the 2019 Dynamic Cubes database of pregnant women diagnosed with cholecystitis and/or cholelithiasis who had undergone cholecystectomy. RESULTS: During 2019, 937 patients with cholelithiasis and cholecystitis were registered, 516 (55%) pregnant and 421 (45%) in puerperium. 91.47% of cases were managed with medical treatment and 8.53% with cholecystectomy, with predominance in the open approach in 63.75% of cases. Mortality was nil in both groups. CONCLUSIONS: Despite current international guidelines recommending early laparoscopic cholecystectomy in pregnant or puerperal women, in Mexico medical treatment, delayed cholecystectomy and its open approach are still privileged.

OBJETIVO: Determinar el tratamiento de elección, el abordaje y la mortalidad en mujeres embarazadas y en puerperio con diagnóstico de litiasis vesicular en México, y compararlo con las recomendaciones de las guías internacionales. MÉTODO: Estudio observacional, descriptivo y retrospectivo basado en la información de la base de datos Cubos Dinámicos del año 2019 de mujeres embarazadas con diagnóstico de colecistitis o colelitiasis que se hubieran realizado colecistectomía. RESULTADOS: En 2019 se registraron 937 pacientes con colelitiasis y colecistitis, 516 (55%) embarazadas y 421 (45%) en puerperio. El 91.47% de los casos se manejaron con tratamiento médico y el 8.53% con colecistectomía, con predominio del abordaje abierto en el 63.75% de los casos. La mortalidad fue nula en ambos grupos. CONCLUSIONES: A pesar de que las guías internacionales actuales recomiendan la colecistectomía laparoscópica temprana en embarazadas y puérperas, en México todavía se privilegian el tratamiento médico, el retraso de la colecistectomía y su abordaje abierto.

Endoscopic Management of Gallbladder Disease.

PURPOSE OF REVIEW: Diseases of the gallbladder can be increasingly managed through endoscopic interventions, either serving as an alternative to or obviating the need for cholecystectomy. In this review, we aim to review the most recent data on endoscopic management of the most common gallbladder diseases. RECENT FINDINGS: The development of lumen-opposing metal stents (LAMS) marked a major shift in gallbladder management, with transmural techniques now well studied for management of cholecystitis. Endoscopic ultrasound (EUS) is also a well-developed technique for gallbladder imaging, comparable or superior to transabdominal ultrasound. Novel techniques with LAMS for gallbladder lesion/polyp resection and treatment of non-cholecystitis gallbladder diseases mark important milestones in gallbladder preservation and increasingly less invasive management of diseases of the gallbladder. There are multiple interventional endoscopic techniques that can be used to manage common gallbladder diseases including cholecystitis, cholelithiasis, gallbladder lesions/polyps, and gallbladder cancer. Ongoing development of novel therapeutic techniques holds promise for additional minimally invasive techniques in the future.

Effect of the COVID-19 pandemic on the care for acute cholecystitis: a Swedish multicentre retrospective cohort study.

OBJECTIVES: The present study aimed to investigate if and how the panorama of acute cholecystitis changed in 2020 in Sweden. Seven aspects were identified, the incidence of cholecystitis, the Tokyo grade, the timing of diagnosis and treatment, the proportion treated with early surgery, the proportion of patients treated with delayed surgery, and new complications from gallstones. DESIGN: Retrospective multicentre cohort study. SETTING: 3 hospitals in Sweden, covering 675 000 inhabitants. PARTICIPANTS: 1634 patients with cholecystitis. OUTCOMES: The incidence, treatment choice and diagnostic and treatment delay were investigated by comparing prepandemic and pandemic patients. RESULTS: Patients diagnosed with cholecystitis during the pandemic were more comorbid (American Society of Anesthesiologists 2-5, 86% vs 81%, p=0.01) and more often had a diagnostic CT (67% vs 59%, p=0.01). There were variations in the number of patients corresponding with the pandemic waves, but there was no overall increase in the number of patients with cholecystitis (78 vs 76 cases/100 000 inhabitants, p=0.7) or the proportion of patients treated with surgery during the pandemic (50% vs 50%, p=0.4). There was no increase in time to admission from symptoms (both median 1 day, p=0.7), or surgery from admission (both median 1 day, p=0.9). The proportion of grades 2-3 cholecystitis was not higher during the pandemic (46% vs 44%, p=0.9). The median time to elective surgery increased (184 days vs 130 days, p=0.04), but there was no increase in new gallstone complications (35% vs 39%, p=0.3). CONCLUSION: Emergency surgery for cholecystitis was not impacted by the pandemic in Sweden. Patients were more comorbid but did not have more severe cholecystitis nor was there a delay in seeking care. Fewer patients non-operatively managed had elective surgery within 6 months of their initial diagnosis but there was no corresponding increase in gallstone complications.

Endoscopic gallbladder inside-stenting combined with aspirated lavage for calculous cholecystitis in poor surgical candidates: a prospective pilot study.

Although long-term stent placement via endoscopic gallbladder stenting (EGBS) reportedly reduces cholecystitis recurrence in patients unfit to undergo cholecystectomy, it can increase the frequency of other late adverse events (AEs) such as cholangitis. This study aimed to examine the feasibility of endoscopic gallbladder inside-stenting (EGB-IS) with lavage and aspiration. This prospective, single-center, pilot study enrolled 83 patients with acute calculous cholecystitis who were poor candidates for surgery. A dedicated catheter with eight side holes was used for lavage and aspiration, and a dedicated single-pigtail stent equipped with a thread was used for EGB-IS. Outcomes such as technical success, clinical success, early AEs, recurrence of cholecystitis, and other symptomatic late AEs associated with EGB-IS with lavage and aspiration were evaluated. The technical and clinical success rates were 80.7% (67/83) and 98.5% (66/67), respectively. The rate of early AEs was 3.6% (3/83). The rate of recurrent cholecystitis was 4.5% (3/66) and that of symptomatic late AEs (besides cholecystitis) was 6.1% (4/66). Consequently, the rate of overall late AEs (cholecystitis plus other events) was 10.6% (7/66). The 1-, 2-, and 3-year cumulative incidence rates of all late AEs were 3.2%, 11.2%, and 18.9%, respectively. EGB-IS with lavage and aspiration for calculous cholecystitis showed promising results in poor surgical candidates. EGB-IS may be useful when EGBS with long-term stent placement is planned, since prevention of cholecystitis recurrence, without a rise in the incidence of other AEs, is anticipated.
