Uncommon Presentation of Xanthogranulomatous Cholecystitis in a True Gallbladder Diverticulum: A Case Report and Literature Review.

BACKGROUND The gallbladder develops from the hepatic diverticulum during the fourth week of gestation, which also give rise to the liver, extrahepatic biliary ducts, and ventral part of the pancreas. Infrequently, the gallbladder has malformation or disruption in embryogenesis, leading to congenital anomalies. There are various congenital anomalies that can arise in the gallbladder. True or congenital diverticulum of the gallbladder is a rare entity that accounts for only 0.06% of gallbladder congenital anomalies and 0.0008% of cholecystectomies at the Mayo Clinic. CASE REPORT Herein, we report a rare case of a 38-year-old woman who presented to Jubail General Hospital's surgery clinic with right upper-quadrant (RUQ) pain associated with vomiting after meals for 1 month. Laparoscopic cholecystectomy was done and gallbladder tissue was sent to histopathology. Gross examination revealed an outpouching mucosa within the wall that was proven to consist of muscularis and serosa layers under light microscope. Interestingly, xanthogranulomatous inflammation was confined to the diverticulum, unlike the chronic inflammation involving the remaining gallbladder. Based on the above findings, the diagnosis of congenital diverticulum with xanthogranulomatous cholecystitis was made. CONCLUSIONS Gallbladders associated with a true diverticulum are uncommonly found to be buried in the liver, leading to surgical difficulties during cholecystectomy. Therefore, background knowledge of occasional anomalies plays a crucial role in guiding the surgeon to choose the optimal method of management. We also discuss the associated complications that accompany these anomalies, such as non-specific prolonged ailments, acalculous cholecystitis, cholecystitis and cholelithiasis, recurrent cholangitis, and carcinoma of the gallbladder.

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.

Gallbladder perforation in acute acalculous vs. calculous cholecystitis: a retrospective comparative cohort study with 10-year single-center experience.

BACKGROUND: Gallstones are a well-known risk factor for acute cholecystitis. However, their role as a risk factor for gallbladder perforation (GBP) remains unclear. Therefore, this study aimed to determine the effect of gallstones on the development of GBP. MATERIALS AND METHODS: This large-scale retrospective cohort study enroled consecutive patients who underwent cholecystectomy for acute cholecystitis. The primary endpoint was the role of gallstones as a risk factor for developing GBP. Secondary endpoints included the clinical characteristics of GBP, other risk factors for GBP, differences in clinical outcomes between patients with acalculous cholecystitis (AC) and calculous cholecystitis (CC), and the influence of cholecystectomy timing. RESULTS: A total of 4497 patients were included in this study. The incidence of GBP was significantly higher in the AC group compared to the CC group (5.6% vs. 1.0%, P <0.001). However, there were no differences in ICU admission and hospital stay durations. The incidence of overall complications was significantly higher in the AC group than in the CC group (2.2% vs. 1.0%, P <0.001). Patients with AC had a higher risk of developing GBP than those with CC (odds ratio, 5.00; 95% CI, 2.94-8.33). In addition, older age (≥60 years), male sex, comorbidities, poor performance status, and concomitant acute cholangitis were associated with the development of GBP. Furthermore, the incidence of GBP was significantly higher in the delayed cholecystectomy group than in the early cholecystectomy group (2.0% vs. 0.9%, P <0.001). CONCLUSIONS: AC is a significant risk factor for GBP. Furthermore, early cholecystectomy can significantly reduce GBP-related morbidity and mortality.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The value of preoperative neutrophil/lymphocyte ratio in predicting the severity of cholecystolithiasis with cholecystitis in elderly patients.

BACKGROUND: This study aims to assess the effectiveness of neutrophil/lymphocyte ratio (NLR) and C-reactive protein (CRP) in diagnosing cholecystolithiasis with cholecystitis in elderly patients. Additionally, the study seeks to determine the predictive value of preoperative NLR in determining the severity of the condition in this population. METHODS: This study is a retrospective cohort study, including 160 elderly patients with cholecystolithiasis with cholecystitis (45 cases of simple cholecystitis, 58 cases of suppurative cholecystitis, 57 cases of gangrenous cholecystitis) and 60 cases of normal gallbladder histology. The study collected clinical data of the patients detected the preoperative CRP content, neutrophil, and lymphocyte levels through blood routine tests, and calculated the NLR value. The diagnostic value of NLR and CRP was determined by using the Receiver Operating Characteristic Curve (ROC), and the optimal value of preoperative NLR related to the severity of elderly patients with cholecystolithiasis with cholecystitis was identified. RESULTS: This study found that for elderly patients with cholecystolithiasis with cholecystitis, preoperative NLR and CRP levels can be used to distinguish the condition. The critical value for NLR was found to be 2.995 (95% CI, 0.9465-0.9853; P < 0.001) with an area under the ROC curve of 0.9659, while the critical value for CRP was 13.05 (95% CI, 0.9284-0.9830; P < 0.001) with an area under the ROC curve of 0.9557. Both NLR and CRP were found to have equivalent diagnostic abilities. Additionally, the study found that there were significant differences in neutrophil and lymphocyte levels in elderly patients with different severity levels, with NLR increasing as severity increased (P < 0.001). The study identified cut-off values for preoperative NLR that could distinguish Simple cholecystitis and Purulent cholecystitis, as well as Purulent cholecystitis and Gangrenous cholecystitis in elderly patients with cholecystolithiasis, with respective AUCs of 0.8441 (95% CI: 0.7642-0.9239; P < 0.001) and 0.7886(95% CI: 0.7050-0.8721, P < 0.001), sensitivities of 91.38% and 87.72%, and specificities of 73.33% and 63.79%. CONCLUSIONS: Preoperative NLR and CRP values can serve as indicators to detect cholecystolithiasis with cholecystitis in elderly patients. Additionally, NLR has been recognized as a potential tool to differentiate the severity of cholecystolithiasis with cholecystitis in the elderly population.
