Meta-Analysis
Occasionally, cholecystectomy is not possible because the patient is not suitable for surgery, and non-operative management should be performed. In these patients, the non-operative management can be through the percutaneous transhepatic gallbladder drainage (PTGBD) or the endoscopic gallbladder drainage. We decided to compare the efficacy and safety of PTGBD and EUS-GBD in the non-operative management of patients with acute cholecystitis. We conducted a systematic review in different databases, such as PubMed, OVID, Medline, and Cochrane Databases. This meta-analysis considers studies published until September 2021. Six studies were selected (2 RCTs). These studies included 749 patients. The mean age was 72.81 ±7.41 years, and males represented 57.4%. EUS-GBD technical success was lower than PTGBD (RR, 0.97; 95% CI, 0.95-0.99), whereas clinical success and adverse events rates were similar in both groups. Twenty-one deaths were reported in all six studies. The global mortality rate was 2.80%, without differences in both groups (2.84% and 2.77% in the EUS-GBD group and the PTGBD groups, respectively). EUS-GBD and PTGBD were successful techniques for gallbladder drainage in patients with acute cholecystitis who are non-tributary for surgery. EUS-GBD has a similar clinical success rate and a similar adverse events rate in comparison to PTGBD. The high technical success and the low adverse events rate of the EUS approach to gallbladder make this technique an excellent alternative for patients with acute cholecystitis who cannot be undergoing surgery.

Review
We aim to investigate the potential of laparoscopic ultrasonography (LUS) as a replacement for intraoperative cholangiography (IOC) in the context of laparoscopic cholecystectomy focusing on various aspects related to both techniques. We made our search through PubMed, Web of Science, Cochrane Library, and Scopus, with the use of the following search strategy: ("laparoscopic ultrasonography" OR LUS OR "laparoscopic US" OR "laparoscopic ultrasound") AND ("laparoscopic cholecystectomy" OR LC). We incorporated diverse studies that addressed our topic, offering data on the identification of biliary anatomy and variations, the utilization of laparoscopic ultrasound in cholecystitis, the detection of common bile duct stones, and the criteria utilized to assess the accuracy of LUS. A total of 1526 articles were screened and only 20 were finally included. This systematic review assessed LUS and IOC techniques in cholecystectomy. IOC showed higher failure rates due to common duct catheterization challenges, while LUS had lower failure rates, often linked to factors like steatosis. Cost-effectiveness comparisons favored LUS over IOC, potentially saving patients money. LUS procedures were quicker due to real-time imaging, while IOC required more time and personnel. Bile duct injuries were discussed, highlighting LUS limitations in atypical anatomies. LUS aided in diagnosing crucial conditions, emphasizing its relevance post surgery. Surgeon experience significantly impacted outcomes, regardless of the technique. A previous study discussed that LUS's learning curve was steeper than IOC's, with proficient LUS users adjusting practices and using IOC selectively. Highlighting LUS's benefits and limitations in cholecystectomy, we stress its value in complex anatomical situations. LUS confirms no common bile duct stones, avoiding cannulation. LUS and IOC equally detect common bile duct stones and visualize the biliary tree. LUS offers safety, speed, cost-effectiveness, and unlimited use. Despite the associated expenses and learning curve, the enduring benefits of using advanced probes in LUS imaging suggest that it could surpass traditional IOC. The validation of this potential advancement relies heavily on incorporating modern probe studies. Our study could contribute to the medical literature by evaluating their clinical validity, safety, cost-effectiveness, learning curve, patient outcomes, technological advancements, and potential impact on guidelines and recommendations for clinical professionals.

Meta-Analysis
INTRODUCTION
Acute care surgery (ACS) was initiated two decades ago to address timeliness and quality in emergency general surgery. We hypothesized that ACS has improved the management of acute appendicitis and biliary disease.
METHODS
A comprehensive systematic review and meta-analysis of outcome studies for emergent appendectomy and cholecystectomy from 1966 to 2017, comparing studies prior to and following ACS implementation, were performed.
RESULTS
Of 1,704 studies, 27 were selected for analysis (appendicitis, 16; biliary pathology, 7; both, 4). Following ACS introduction, the complication rate was significantly reduced in both appendectomy and cholecystectomy (risk ratios, 0.70; 95% confidence interval [CI], 0.57-0.85; I = 9.2% and relative risk, 0.62; 95% CI, 0.41-0.94; I = 63.5%) respectively. There was a significant reduction in the time from arrival in emergency until admission and from admission to operation (-1.37 hours: 95% CI, -1.93 to -0.80; -2.51 hours: 95% CI, -4.44 to -0.58) in the appendectomy cohort. Time to operation was shorter in the cholecystectomy group (-6.46 hours; 95% CI, -9.54 to -3.4). Length of hospital stay was reduced in both groups (appendectomy, -0.9 day; cholecystectomy, -1.09 day). There was a reduction in overall cost in cholecystectomy group (-US $854.37; 95% CI, -1,554.1 to -154.05). No statistical significance was detected for wound infection, abscess, conversion of laparoscopy to open technique, rate of negative appendectomy, after hours, readmission, and cost.
CONCLUSION
The implementation of ACS models in general surgery emergency care has significantly improved system and patient outcomes for appendicitis and biliary pathology.

Comparison of the safety profile, conversion rate and hospitalization duration between early and delayed laparoscopic cholecystectomy for acute cholecystitis: a systematic review and meta-analysis.
BACKGROUND
Although the past decade has witnessed unprecedented medical progress, no consensus has been reached on the optimal approach for patients with acute cholecystitis. Herein, we conducted a systematic review and meta-analysis to assess the differences in patient outcomes between Early Laparoscopic Cholecystectomy (ELC) and Delayed Laparoscopic Cholecystectomy (DLC) in the treatment of acute cholecystitis. Our protocol was registered in the PROSPERO database (registration number: CRD42023389238).
OBJECTIVES
We sought to investigate the differences in efficacy, safety, and potential benefits between ELC and DLC in acute cholecystitis patients by conducting a systematic review and meta-analysis.
METHODS
The online databases PubMed, Springer, and the Cochrane Library were searched for randomized controlled trials (RCTs) and retrospective studies published between Jan 1, 1999 and Jan 1, 2022.
RESULTS
21 RCTs and 13 retrospective studies with a total of 7,601 cases were included in this research. After a fixed-effects model was applied, the pooled analysis showed that DLC was associated with a significantly high conversion rate (OR: 0.6247; 95%CI: 0.5115-0.7630; z = -4.61, < 0.0001) and incidence of postoperative complications (OR: 0.7548; 95%CI: 0.6197-0.9192; z = -2.80, = 0.0051). However, after applying a random-effects model, ELC was associated with significantly shorter total hospitalization duration than DLC (MD: -4.0657; 95%CI: -5.0747 to -3.0566; z = -7.90, < 0.0001).
CONCLUSION
ELC represents a safe and feasible approach for acute cholecystitis patients since it shortens hospitalization duration and decreases the incidence of postoperative complications of laparoscopic cholecystectomy.

Review
Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has been introduced as an alternative to percutaneous transhepatic gallbladder drainage for the treatment of acute cholecystitis in non-surgical candidates. A systematic review of the English language literature through PubMed search until June 2014 was conducted. One hundred and fifty-five patients with acute cholecystitis treated with EUS-GBD in eight studies and 12 case reports, and two patients with EUS-GBD for other causes were identified. Overall, technical success was obtained in 153 patients (97.45%) and clinical success in 150 (99.34%) patients with acute cholecystitis. Adverse events developed in less than 8% of patients, all of them managed conservatively. EUS-GBD has been performed with plastic stents, nasobiliary drainage tubes, standard or modified tubular self-expandable metal stents (SEMS) and lumen-apposing metal stents (LAMS) by different authors with apparently similar outcomes. No comparison studies between stent types for EUS-GBD have been reported. EUS-GBD is a promising novel alternative intervention for the treatment of acute cholecystitis in high surgical risk patients. Feasibility, safety and efficacy in published studies from expert centers are very high compared to currently available alternatives. Further studies are needed to establish the safety and long-term outcomes of this procedure in other practice settings before EUS-GBD can be widely disseminated.

Review
BACKGROUND
Acute cholecystitis (AC) is a common differential for patients presenting to the emergency department (ED) with abdominal pain. The diagnostic accuracy of history, physical examination, and bedside laboratory tests for AC have not been quantitatively described.
OBJECTIVES
We performed a systematic review to determine the utility of history and physical examination (H&P), laboratory studies, and ultrasonography (US) in diagnosing AC in the ED.
METHODS
We searched medical literature from January 1965 to March 2016 in PubMed, Embase, and SCOPUS using a strategy derived from the following formulation of our clinical question: patients-ED patients suspected of AC; interventions-H&P, laboratory studies, and US findings commonly used to diagnose AC; comparator-surgical pathology or definitive diagnostic radiologic study confirming AC; and outcome-the operating characteristics of the investigations in diagnosing AC were calculated. Sensitivity, specificity, and likelihood ratios (LRs) were calculated using Meta-DiSc with a random-effects model (95% CI). Study quality and risks for bias were assessed using the Quality Assessment Tool for Diagnostic Accuracy Studies.
RESULTS
Separate PubMed, Embase, and SCOPUS searches retrieved studies for H&P (n = 734), laboratory findings (n = 74), and US (n = 492). Three H&P studies met inclusion/exclusion criteria with AC prevalence of 7%-64%. Fever had sensitivity ranging from 31% to 62% and specificity from 37% to 74%; positive LR [LR+] was 0.71-1.24, and negative LR [LR-] was 0.76-1.49. Jaundice sensitivity ranged from 11% to 14%, and specificity from 86% to 99%; LR+ was 0.80-13.81, and LR- was 0.87-1.03. Murphy's sign sensitivity was 62% (range = 53%-71%), and specificity was 96% (range = 95%-97%); LR+ was 15.64 (range = 11.48-21.31), and LR- was 0.40 (range = 0.32-0.50). Right upper quadrant pain had sensitivity ranging from 56% to 93% and specificity of 0% to 96%; LR+ ranged from 0.92 to 14.02, and LR- from 0.46 to 7.86. One laboratory study met criteria with a 26% prevalence of AC. Elevated bilirubin had a sensitivity of 40% (range = 12%-74%) and specificity of 93% (range = 77%-99%); LR+ was 5.80 (range = 1.25-26.99), and LR- was 0.64 (range = 0.39-1.08). Five US studies with a prevalence of AC of between 10% and 46%. US sensitivity was 86% (range = 78%-94%) and specificity was 71% (range = 66%-76%); LR+ was 3.23 (range = 1.74-6.00), and LR- was 0.18 (range = 0.10-0.33).
CONCLUSION
Variable disease prevalence, coupled with limited sample sizes, increases the risk of selection bias. Individually, none of these investigations reliably rule out AC. Development of a clinical decision rule to include evaluation of H&P, laboratory data, and US are more likely to achieve a correct diagnosis of AC.

Meta-Analysis Review
BACKGROUND
Acute cholecystitis (AC) is a surgical condition that is usually managed by emergency surgery. The presence of common bile duct stones (CBDS) in this setting mandates definitive treatment to avoid complications such as cholangitis. The incidence of CBDS in the setting of AC is poorly defined.
METHODS
A systematic English literature search was conducted in PubMed, MEDLINE and Embase to determine the incidence of CBDS in patients presenting with AC. Outlier studies identified by funnel plot analysis were excluded and the incidence of CBDS was identified. The mean CBD diameter and liver function test values of patients with AC and CBDS were calculated.
RESULTS
Data were extracted from 19 studies representing a total 4057 patients with AC. Routine biliary imaging was not performed in all studies. The pooled incidence of CBDS was 13.7% (95% confidence interval 11.8-15.9). The incidence of unsuspected retained CBDS was 1.1%. Histologically confirmed cases of AC had a similar rate of CBDS compared to those diagnosed clinically. The mean CBD diameter of patients with AC and CBDS was 7.2 mm compared to 5.8 mm without. Liver function test values in the presence of CBDS were more likely to be deranged, with gamma-glutamyltransferase the most sensitive and specific marker for CBDS in the setting of AC.
CONCLUSION
CBDS is present in a significant proportion of patients presenting with AC. Routine biliary imaging is advised in all patients presenting with AC where possible.

Meta-Analysis
INTRODUCTION
Acute cholecystitis (AC) is the most common biliary stone disease complication. While there is consensus regarding cholecystectomy for AC, gallbladder drainage is indicated in elderly or high-risk surgical patients.
EVIDENCE ACQUISITION
We systematically reviewed available evidence in the field of EUS-guided gallbladder drainage (EUS-GBD) for AC in high-risk surgical patients. The studies were classified according to their level of evidence (LE) according to the Oxford Centre for Evidence Based Medicine classification.
EVIDENCE SYNTHESIS
Literature search retrieved 175 manuscripts; most of them were expert opinions (LE V, N.=53) or case-series (LE IV, N.=29). There was no meta-analysis of RCT (LE Ia), while two randomized controlled trials (LE Ib) demonstrated that EUS-GBD was superior to percutaneous transhepatic-GBD (PT-GBD) regarding long-term outcomes (adverse events, recurrent cholecystitis, and reintervention). Several meta-analyses of cohort studies (LE IIa, N.=11) were designed to compare the three available drainage strategies (endoscopic, echoendoscopic and percutaneous) and to assess the pooled risk of adverse events. Comparison between surgery and EUS-GBD was done in a single retrospective study with a propensity score analysis (LE III). The outcomes of conversion from PT-GBD to EUS-GBD were covered by few retrospective studies (LE III). Several manuscripts (N.=69) were published on EUS-GBD as a rescue strategy in case of malignant biliary obstruction.
CONCLUSIONS
The levels of evidence of EUS-GBD in the literature have evolved from initial descriptive studies to recent randomized controlled trials and meta-analysis of cohort studies. While several articles addressed the comparison among different techniques for GBD, in our opinion some topics and questions have not been adequately investigated. are still debated.

Review
PURPOSE
Fluorescence-based imaging has found application in several fields of elective surgery, but there is still a lack of evidence in the literature about its use in emergency setting. The present review critically summarizes currently available applications and limitations of indocyanine green (ICG) fluorescence in abdominal emergencies including acute cholecystitis, mesenteric ischemia, and trauma surgery.
METHODS
A systematic review was performed according to the PRISMA statement identifying articles about the use of ICG fluorescence in the management of the most common general surgery emergency. Only studies focusing on the use of ICG fluorescence for the management of acute surgical conditions in adults were included.
RESULTS
Thirty-six articles were considered for qualitative analysis. The most frequent disease was occlusive or non-occlusive mesenteric ischemia followed by acute cholecystitis. Benefits from using ICG for acute cholecystitis were reported in 48% of cases (clear identification of biliary structures and a safer surgical procedure). In one hundred and twenty cases that concerned the use of ICG for occlusive or non-occlusive mesenteric ischemia, ICG injection led to a modification of the surgical decision in 44 patients (36.6%). Three studies evaluated the use of ICG in trauma patients to assess the viability of bowel or parenchymatous organs in abdominal trauma, to evaluate the perfusion-related tissue impairment in extremity or craniofacial trauma, and to reassess the efficacy of surgical procedures performed in terms of vascularization. ICG injection led to a modification of the surgical decision in 50 patients (23.9%).
CONCLUSION
ICG fluorescence is a safe and feasible tool also in an emergency setting. There is increasing evidence that the use of ICG fluorescence during abdominal surgery could facilitate intra-operative decision-making and improve patient outcomes, even in the field of emergency surgery.

Meta-Analysis
BACKGROUND AND AIMS
The optimal method of gallbladder drainage (GBD) for acute cholecystitis in nonsurgical candidates is uncertain. The aim of the current study was to conduct a network meta-analysis comparing the 3 methods of GBD (percutaneous [PT], endoscopic transpapillary [ETP], and EUS-guided).
METHODS
A comprehensive literature search for all comparative studies assessing the efficacy of either 2 or all modalities used for treatment of acute cholecystitis in patients at high risk for cholecystectomy was performed. Primary outcomes of technical and clinical success and postprocedure adverse events were assessed. Secondary outcomes were reintervention, unplanned readmissions, recurrent cholecystitis, and mortality.
RESULTS
Ten studies were identified, comprising 1267 patients (472 EUS-GBD, 493 PT-GBD, and 302 ETP-GBD). In the network ranking estimate, PT-GBD and EUS-GBD had the highest likelihood of technical success (EUS-GBD vs PT-GBD vs ETP-GBD: 2.00 vs 1.02 vs 2.98) and clinical success (EUS-GBD vs PT-GBD vs ETP-GBD: 1.48 vs 1.55 vs 2.98). EUS-GBD had the lowest risk of recurrent cholecystitis (EUS-GBD vs PT-GBD vs ETP-GBD: 1.089 vs 2.02 vs 2.891). PT-GBD had the highest risk of reintervention (EUS-GBD vs PT-GBD vs ETP-GBD: 1.81 vs 2.99 vs 1.199) and unplanned readmissions (EUS-GBD vs PT-GBD vs ETP-GBD: 1.582 vs 2.944 vs 1.474), whereas ETP-GBD was associated with the lowest rates of mortality (EUS-GBD vs PT-GBD vs ETP-GBD: 2.62 vs 2.09 vs 1.29).
CONCLUSIONS
The 3 modalities of GBD have their respective advantages and disadvantages. Selection of technique will depend on available expertise. In centers with expertise in endoscopic GBD, the techniques are preferred over PT-GBD with improved outcomes. (Clinical trial registration number: CRD42020181972.).
