Meta-analysis comparing early versus delayed laparoscopic cholecystectomy for acute cholecystitis

Paradigm shift towards emergency cholecystectomy: one site experience of the Chole-QuiC process

INTRODUCTION

Substantial evidence exists for the superiority of emergency over delayed cholecystectomy for gallstone disease during primary admission. Despite this, emergency surgery rates in the UK remain low compared with other developed countries, with great variation in care across the nation. We aimed to describe the local paradigm shift towards emergency surgery and investigate outcomes.

METHODS

This is a prospective observational study examining patients enrolled onto an emergency cholecystectomy pathway, following the hospital's subscription to the Royal College of Surgeons of England's Cholecystectomy Quality Improvement Collaborative (Chole-QuIC), between 1 December 2021 and 31 January 2023. Multivariate logistical regression models were used to identify patient and hospital factors associated with postoperative outcomes.

RESULTS

Of the 307 suitable acute admissions, 261 (85%) had an emergency cholecystectomy, compared with 5% preceding the Chole-QuIC interventions. Waiting time dropped from 67 to 5 days. A total of 208 (79.7%) patients were primary presentations, 92 (35.2%) were classed Tokyo grade 2 and 142 (54.4%) were obese. A total of 23 (8.8%) patients underwent preoperative endoscopic retrograde cholangiopancreatography, and 26 (10%) patients had a subtotal cholecystectomy. Favourable outcomes (Clavien Dindo ≥3) were observed in first presentations (odds ratio (OR) 0.35; p=0.042) and for operation times within 7 days (OR 0.32; p=0.037), with worse outcomes in BMI ≥35 (OR 3.32; p=0.005) and operation time >7 days (OR 3.11; p=0.037).

CONCLUSION

A paradigm shift towards emergency cholecystectomy benefits both the patient and the service. Positive outcomes are apparent for early operation in patients presenting for the first time and recurrent attendees, with early operation (<7 days) providing the most favourable outcome in a select patient group.

Management of acute cholecystitis in patients on anti-thrombotic therapy: A single center experience

Background

Acute cholecystitis in patients on anti-thrombotic therapy (ATT) presents a clinical dilemma at the intersection between conflicting guidelines, specifically between timing of early operative management (OM) versus time-to-reversal of certain ATT agents. With growing recognition that nonoperative management (NOM) is associated with considerable morbidity, and evidence in the literature that early OM in patients on ATT is safe, we reviewed our own practice to examine how we addressed these conflicting guidelines.

Materials and methods

We performed a retrospective review of patients with acute cholecystitis between December 2017 and March 2022. Patients were classified as ATT or non-ATT; ATT patients were subdivided into anticoagulation (AC) and antiplatelet (AP) groups. Rates of OM were compared.

Results

502 patients with acute cholecystitis were identified, 464 non-ATT and 38 ATT. 30 ATT patients were on AC, 7 on AP, and 1 on both. Non-ATT patients were significantly more likely to receive OM at index presentation compared to those on ATT: 89.9 % vs 63.2 % (p < 0.05). Subgroup analysis of the ATT group showed AP patients were significantly less likely to receive OM compared to those on AC, 12.5 % vs 77 % (p < 0.05).

Conclusions

At our institution, patients on ATT were significantly less likely to undergo OM for acute cholecystitis compared with non-ATT patients. Those on AC received OM significantly more than patients on AP. Further study is needed to better define the management of this growing population so that acute cholecystitis guidelines might address this issue in the future.

Safe postoperative outcomes following early cholecystectomy for acute calculus cholecystitis regardless of symptom onset

Objectives

There is growing evidence for reduced post-operative complications, and lower hospital costs associated with early cholecystectomy for acute calculus cholecystitis (AC) compared to delayed surgery. Limited high-quality evidence exists for how early, if at all, should surgeons be operating emergently for AC based on symptom onset.

Material and Methods

Seven hundred seventy-four patients who had cholecystectomy performed by a single surgeon between January 2015-October 2022 were retrospectively reviewed. Five hundred fourty-one patients were analysed. Patients were divided into three groups based on symptom onset: Group 1: 0-72 hours (n= 305), Group 2: 72 hrs-1 week (n= 154) and Group 3: >1 week (n= 82).

Results

Median operative time was most prolonged in Group 2 (96.5 minutes), and had the greatest proportion of reconstituting 95% cholecystectomies (n= 22/154, 14.29%) compared to Group 1 (p> 0.05). The conversion to open was between 0.65-1.64% in all groups. The greatest proportion of bile leak occurred in Group 1 (n= 7/305, 2.3%) followed by Group 3 (n= 1/82, 1.22%) (p> 0.05). All were successfully managed with ERCP and biliary stent. Median hospital stay was significantly prolonged in Group 2 (2.3 days) compared to Group 1 (2 days) (p= 0.03). The proportion of 95% cholecystectomies in Group 2 and 3 were not significant compared to Group 1.

Conclusion

Early cholecystectomy for calculus cholecystitis, irrespective of the timing of symptoms appears to have safe postoperative outcomes. Surgeons do not necessarily need to limit early cholecystectomy for within 72 hours of symptom onset.

Acute cholecystitis in old adults: the impact of advanced age on the clinical characteristics of the disease and on the surgical outcomes of laparoscopic cholecystectomy

BACKGROUND

Impact of advanced age on disease characteristics of acute cholecystitis (AC), and surgical outcomes after laparoscopic cholecystectomy (LC) has not been established.

METHODS

This single-center retrospective study included patients who underwent LC for AC between April 2010 and December 2020. We analyzed the disease characteristics and surgical outcomes according to age: Group 1 (age < 60 years), Group 2 (60 ≤ age < 80 years), and Group 3 (age ≥ 80 years). Risk factors for complications were assessed using logistic regression analysis.

RESULTS

Of the 1,876 patients (809 [43.1%] women), 723 were in Group 1, 867 in Group 2, and 286 in Group 3. With increasing age, the severity of AC and combined common bile duct stones increased. Group 3 demonstrated significantly worse surgical outcomes when compared to Group 1 and 2 for overall (4.0 vs. 9.1 vs. 18.9%, p < 0.001) and serious complications (1.2 vs. 4.2 vs. 8.0%, p < 0.001), length of hospital stay (2.78 vs. 3.72 vs. 5.87 days, p < 0.001), and open conversion (0.1 vs. 1.0 vs. 2.1%, p = 0.007). Incidental gallbladder cancer was also the most common in Group 3 (0.3 vs. 1.5 vs. 3.1%, p = 0.001). In the multivariate analysis, body mass index < 18.5, moderate/severe AC, and albumin < 2.5 g/dL were significant risk factors for serious complications in Group 3.

CONCLUSION

Advanced age was associated with severe AC, worse surgical outcomes, and a higher rate of incidental gallbladder cancer following LC. Therefore, in patients over 80 years of age with AC, especially those with poor nutritional status and high severity grading, urgent surgery should be avoided, and surgery should be performed after sufficient supportive care to restore nutritional status before LC.

Racial disparities in time to laparoscopic cholecystectomy for acute cholecystitis

BACKGROUND

Disparities in healthcare exist, yet few data are available on racial differences in time from admission to surgery. This study aimed to compare time from admission to laparoscopic cholecystectomy for acute cholecystitis between non-Hispanic Black and non-Hispanic White patients.

METHODS

Patients who underwent laparoscopic cholecystectomy for acute cholecystitis from 2010 to 2020 were identified using NSQIP. Time to surgery and additional preoperative, operative, and postoperative variables were analyzed.

RESULTS

In the univariate analysis, 19.4% of Black patients experienced a time to surgery >1 day compared with 13.4% of White patients (p < 0.0001). In the multivariable analysis, controlling for potential confounding factors, Black patients were found to be more likely than White patients to experience a time to surgery >1 day (OR 1.23, 95% CI 1.17-1.30, p < 0.0001).

CONCLUSIONS

Further investigation is indicated to better define the nature and significance of gender, race, and other biases in surgical care. Surgeons should be aware that biases may adversely impact patient care and should strive to identify and proactively address them to promote health equity in surgery.

Management of Acute Cholecystitis in High-Risk Patients: Percutaneous Gallbladder Drainage as a Definitive Treatment vs. Emergency Cholecystectomy-Systematic Review and Meta-Analysis

BACKGROUND

This systematic review aims to investigate whether percutaneous transhepatic gallbladder biliary drainage (PTGBD) is superior to emergency cholecystectomy (EC) as a definitive treatment in high-risk patients with acute cholecystitis (AC).

MATERIAL AND METHODS

A systematic literature search was performed until December 2022 using the Scopus, Medline/PubMed and Web of Science databases.

RESULTS

Seventeen studies have been included with a total of 783,672 patients (32,634 treated with PTGBD vs. 4663 who underwent laparoscopic cholecystectomy, 343 who had open cholecystectomy and 746,032 who had some form of cholecystectomy, but without laparoscopic or open approach being specified). An analysis of the results shows that PTGBD, despite being less invasive, is not associated with lower morbidity with respect to EC (RR 0.77 95% CI [0.44 to 1.34]; I2 = 99%; p = 0.36). A lower postoperative mortality was reported in patients who underwent EC (2.37%) with respect to the PTGBD group (13.78%) (RR 4.21; 95% CI [2.69 to 6.58]; p < 0.00001); furthermore, the risk of hospital readmission for biliary complications (RR 2.19 95% CI [1.72 to 2.79]; I2 = 48%; p < 0.00001) and hospital stay (MD 4.29 95% CI [2.40 to 6.19]; p < 0.00001) were lower in the EC group.

CONCLUSIONS

In our systematic review, the majority of studies have very low-quality evidence and more RCTs are needed; furthermore, PTGBD is inferior in the treatment of AC in high-risk patients. The definition of high-risk patients is important in interpreting the results, but the methods of assessment and definitions differ between studies. The results of our systematic review and meta-analysis failed to demonstrate any advantage of using PTGBD over ER as a definitive treatment of AC in critically ill patients, which suggests that EC should be considered as the treatment of choice even in very high-risk patients. Most likely, the inferiority of PTGBD versus early LC for high-risk patients is related to an association of various patient-side factor conditions and the severity of acute cholecystitis.

The Accuracy of Point-of-Care Ultrasound (POCUS) in Acute Gallbladder Disease

There is increasing recognition that point-of-care ultrasound (POCUS), performed by the clinician at the bedside, can be a natural extension of the clinical examination—the modern abdominal “stethoscope” and provides an opportunity to expedite the care pathway for patients with acute gallbladder disease. The primary aims of this study were to benchmark the accuracy of surgeon-performed POCUS in suspected acute gallbladder disease against standard radiology or pathology reports and to compare time to POCUS diagnosis with time to definitive imaging. This prospective single-arm observational cohort study was conducted in four hospitals in Ireland, Italy, and Portugal to assess the accuracy of POCUS against standard radiology in patients with suspected acute biliary disease (ClinicalTrials.govIdentifier: NCT02682368). The findings of surgeon-performed POCUS were compared with those on definitive imaging or surgery. Of 100 patients recruited, 89 were suitable for comparative analysis, comparing POCUS with radiological findings in 84 patients and with surgical/histological findings in five. The overall global accuracy of POCUS was 88.7% (95% CI, 80.3–94.4%), with a sensitivity of 94.7% (95% CI, 85.3–98.9%), a specificity of 78.1% (95% CI, 60.03–90.7%), a positive likelihood ratio (LR+) of 4.33 and negative likelihood ratio (LR) of 0.07. The mean time from POCUS to the final radiological report was 11.9 h (range 0.06–54.9). In five patients admitted directly to surgery, the mean time between POCUS and incision was 2.30 h (range 1.5–5), which was significantly shorter than the mean time to formal radiology report. Sixteen patients were discharged from the emergency department, of whom nine did not need follow-up. Our study is one of the very few to demonstrate a high concordance between surgeon-performed POCUS of patients without a priori radiologic diagnosis of gallstone disease and shows that the expedited diagnosis afforded by POCUS can be reliably leveraged to deliver earlier definitive care for patients with acute gallbladder pathology, as the general surgeon skilled in POCUS is uniquely positioned to integrate it into their bedside assessment.

The influence of frailty on outcomes for older adults admitted to hospital with benign biliary disease: a single-centre, observational cohort study

INTRODUCTION

The prevalence and complications of biliary disease increase with age. Frailty has been associated with adverse outcomes in the hospital setting. We describe the prevalence of frailty in older patients hospitalised with benign biliary disease and its association with duration of hospital stay, and 90-day and 1-year mortality.

METHODS

We performed a retrospective cohort study of patients aged 75 years and over admitted with acute biliary disease between 17 September 2014 and 20 March 2017. Clinical Frailty Scale (CFS) score was recorded on admission.

RESULTS

We included 200 patients with a median age of 82 (75-99) years, 60% were female; 154 (77%) were independent for personal activities of daily living (ADLs) and 99 (49.5%) for instrumental ADLs. Cholecystitis was the most common diagnosis (43%) followed by cholangitis (36%) and pancreatitis (21%). Ninety-nine patients were non frail (NF; CFS 1-4) and 101 were frail (F; CFS 5-9). Some 104 patients received medical treatment only. Surgery was more common in NF patients (11% vs F 2%), percutaneous drainage more frequently performed in F patients (15% vs NF 5%) and endoscopic cholangiopancreatography was similar in both groups (F 32% vs NF 31%). Frailty was associated with worse clinical outcomes in F vs NF: functional deconditioning (34% vs 11%), increased care level (19% vs 3%), length of stay (12 vs 7 days), 90-day mortality (8% vs 3%) and 1-year mortality (48% vs 24%).

CONCLUSIONS

Half of patients in our cohort were frail and spent longer in hospital, were less likely to undergo surgery and were less likely to remain alive at 1 year after discharge.

Early laparoscopic cholecystectomy for acute cholecystitis: should we operate beyond the first week?

BACKGROUND

The deadline for early laparoscopic cholecystectomy (ELC) in patients with acute calculous cholecystitis (ACC) is the subject of much debate. The aim of this study was to assess outcomes of ELC in patients with more than 7 days of symptoms.

METHODS

It is a retrospective analysis of 564 patients having undergone ELC for ACC between January 2003 and June 2021. Patients were divided into two groups according to the timing between the onset of symptoms and surgery: group 1 (G1), within the first 7 days of symptoms, and group 2 (G2) after day 7 of symptoms.

RESULTS

Apart from a longer operative time (G1 80 min vs. G2 90 min; p = 0.016), there were no significant differences regarding conversion rate (G1 14.5% vs. G2 13.2%; p = 0.748), both intra- and postoperative complications, mainly bile duct injuries (G1 0.2% vs. G2 0%; p = 1) and bile leakage (G1 1.2% vs. G2 0%; p = 1) and postoperative length of stay (G1 2 days [1-3] vs. G2 2 days [1-4]; p = 0.125).

CONCLUSION

Early laparoscopic cholecystectomy could be proposed for patients with acute calculous cholecystitis even beyond 7 days of symptoms.

The incidence, operative difficulty and outcomes of staged versus index admission laparoscopic cholecystectomy and bile duct exploration for all comers: a review of 5750 patients

BACKGROUND

The timing of laparoscopic cholecystectomy (LC) for emergency biliary admissions remains inconsistent with national and international guidelines. The perception that LC is difficult in acute cholecystitis and the popularity of the two-session approach to pancreatitis and suspected choledocholithiasis result in delayed management.

METHODS

Analysis of prospectively maintained data in a unit adopting a policy of "intention to treat" during the index admission. The aim was to study the incidence of previous biliary admissions and compare the operative difficulty, complications and postoperative outcomes with patients who underwent index admission LC.

RESULTS

Of the 5750 LC performed, 20.8% had previous biliary episodes resulting in one admission in 93% and two or more in 7%. Most presented with biliary colic (39.6%) and acute cholecystitis (27.6%). A previous biliary history was associated with increased operative difficulty (p < 0.001), longer operating times (86.9 vs. 68.1 min, p < 0.001), more postoperative complications (7.8% vs. 5.4%, p = 0.002) and longer hospital stay (8.1 vs. 5.5 days, p < 0.001) and presentation to resolution intervals. However, conversion and mortality rates showed no significant differences.

CONCLUSION

Index admission LC is superior to interval cholecystectomy and should be offered to all patients fit for general anaesthesia regardless of the presenting complaints. Subspecialisation should be encouraged as a major factor in optimising resource utilisation and postoperative outcomes of biliary emergencies.

Impact of the first wave of COVID-19 on outcomes following emergency admissions for common acute surgical conditions: analysis of a national database in England

Background

This study assessed the impact of the first COVID-19 wave in England on outcomes for acute appendicitis, gallstone disease, intestinal obstruction, diverticular disease, and abdominal wall hernia.

Methods

Emergency surgical admissions for patients aged 18 years and older to 124 NHS Trust hospitals between January and June in 2019 and 2020 were extracted from Hospital Episode Statistics. The risk of 90-day mortality after admission during weeks 11–19 in 2020 (national lockdown) and 2019 (pre-COVID-19) was estimated using multilevel logistic regression with case-mix adjustment. The primary outcome was all-cause mortality at 90 days.

Results

There were 12 231 emergency admissions and 564 deaths within 90 days during weeks 11–19 in 2020, compared with 18 428 admissions and 542 deaths in the same interval in 2019. Overall, 90-day mortality was higher in 2020 versus 2019, with an adjusted OR of 1.95 (95 per cent c.i. 0.78 to 4.89) for appendicitis, 2.66 (1.81 to 3.92) for gallstone disease, 1.99 (1.44 to 2.74) for diverticular disease, 1.70 (1.13 to 2.55) for hernia, and 1.22 (1.01 to 1.47) for intestinal obstruction. After emergency surgery, 90-day mortality was higher in 2020 versus 2019 for gallstone disease (OR 3.37, 1.26 to 9.02), diverticular disease (OR 2.35, 1.16 to 4.73), and hernia (OR 2.34, 1.23 to 4.45). For intestinal obstruction, the corresponding OR was 0.91 (0.59 to 1.41). For admissions not leading to emergency surgery, mortality was higher in 2020 versus 2019 for gallstone disease (OR 2.55, 1.67 to 3.88), diverticular disease (1.90, 1.32 to 2.73), and intestinal obstruction (OR 1.30, 1.06 to 1.60).

Conclusion

Emergency admission was reduced during the first lockdown in England and this was associated with higher 90-day mortality.

Cost analysis of index versus delayed cholecystectomy for acute cholecystitis in a New Zealand Provincial Centre

BACKGROUND

Evidence suggests index cholecystectomy (IC) in patients with acute cholecystitis is safe, has decreased hospital stay and is cheaper than delayed cholecystectomy (DC). Costs of cholecystectomy have not previously been investigated in New Zealand. The aim of this study was to compare cost of IC with DC for patients with acute cholecystitis.

METHODS

A retrospective analysis of adults admitted to Northland hospitals with acute cholecystitis between 1 January 2015 and 31 December 2019 who underwent subsequent cholecystectomy, was performed. Actual patient-level costs were utilized for cost comparison between IC and DC. Factors associated with increased costs were assessed using multivariate analysis.

RESULTS

Two hundred and eleven patients were included in the study; 72 (34%) underwent IC and 139 (65%) DC. There was no significant difference in total cost for IC ($12 767) versus DC ($12 029) (p = 0.192); this persisted on multivariate analysis. Patients having IC had more severe cholecystitis, and 90-day representation rate following DC was 35%. Costs were increased by severity of cholecystitis, age, American Society of Anesthesiology score (ASA) and travel distance.

CONCLUSION

This study showed there is no significant difference in cost between IC and DC for patients with acute cholecystitis in Northland, New Zealand. Severity, increasing age, ASA and travel distance were drivers of costs. To recognize the cost benefits of IC, it is likely that increased rates of IC are needed.

Effectiveness of emergency surgery for five common acute conditions: an instrumental variable analysis of a national routine database

The effectiveness of emergency surgery vs. non-emergency surgery strategies for emergency admissions with acute appendicitis, gallstone disease, diverticular disease, abdominal wall hernia or intestinal obstruction is unknown. Data on emergency admissions for adult patients from 2010 to 2019 at 175 acute National Health Service hospitals in England were extracted from the Hospital Episode Statistics database. Cohort sizes were: 268,144 (appendicitis); 240,977 (gallstone disease); 138,869 (diverticular disease); 106,432 (hernia); and 133,073 (intestinal obstruction). The primary outcome was number of days alive and out of hospital at 90 days. The effectiveness of emergency surgery vs. non-emergency surgery strategies was estimated using an instrumental variable design and is reported for the cohort and pre-specified sub-groups (age, sex, number of comorbidities and frailty level). Average days alive and out of hospital at 90 days for all five cohorts were similar, with the following mean differences (95%CI) for emergency surgery minus non-emergency surgery after adjusting for confounding: -0.73 days (-2.10-0.64) for appendicitis; 0.60 (-0.10-1.30) for gallstone disease; -2.66 (-15.7-10.4) for diverticular disease; -0.07 (-2.40-2.25) for hernia; and 3.32 (-3.13-9.76) for intestinal obstruction. For patients with 'severe frailty', mean differences (95%CI) in days alive and out of hospital for emergency surgery were lower than for non-emergency surgery strategies: -21.0 (-27.4 to -14.6) for appendicitis; -5.72 (-11.3 to -0.2) for gallstone disease, -38.9 (-63.3 to -14.6) for diverticular disease; -19.5 (-26.6 to -12.3) for hernia; and - 34.5 (-46.7 to -22.4) for intestinal obstruction. For patients without frailty, the mean differences (95%CI) in days alive and out of hospital were: -0.18 (-1.56-1.20) for appendicitis; 0.93 (0.48-1.39) for gallstone disease; 5.35 (-2.56-13.28) for diverticular disease; 2.26 (0.37-4.15) for hernia; and 18.2 (14.8-22.47) for intestinal obstruction. Emergency surgery and non-emergency surgery strategies led to similar average days alive and out of hospital at 90 days for five acute conditions. The comparative effectiveness of emergency surgery and non-emergency surgery strategies for these conditions may be modified by patient factors.

Single Incision Cholecystectomies for Acute Cholecystitis: A Single Surgeon Series from the Caribbean

Introduction. Single incision laparoscopic surgery (SILS) is accepted as a safe alternative to conventional multiport laparoscopic (MPL) cholecystectomy for benign gallbladder disease. Since many surgeons carefully select patients without inflammation, there are limited data on SILS for acute cholecystitis. We report a single surgeon experience with SILS cholecystectomy for patients with acute cholecystitis. Materials and Methods. After securing ethical approval, we performed an audit of all SILS cholecystectomies for acute cholecystitis by a single surgeon from January 1, 2009, to December 31, 2019. The following data were extracted: patient demographics, intraoperative details, surgical techniques, specialized equipment utilized, conversions (additional port placement), morbidity, and mortality. Data were analyzed using SPSS 12.0. Results. SILS cholecystectomy was performed in 25 females at a mean age of 35 ± 4.1 (SD) years and a mean BMI of 31.9 ± 3.8 (SD) using a direct fascial puncture technique without access platforms. The operations were completed in 83 ± 29.4 minutes (mean ± SD) with an estimated blood loss of 76.9 ± 105 (mean + SD). Three (12%) patients required additional 5 mm port placement (conversions), but no open operations were performed. The patients were hospitalized for 1.96 ± 0.9 days (mean ± SD). There were 2 complications: postoperative superficial SSI (grade I) and a diaphragmatic laceration (grade III). No bile duct injuries were reported. There were 9 patients with complicated acute cholecystitis, and this sub-group had longer mean operating times (109.2 ± 27.3 minutes) and mean postoperative hospital stay (1.3 ± 0.87 days). Conclusion. The SILS technique is a feasible and safe approach to perform cholecystectomy for acute cholecystitis. We advocate a low threshold to place additional ports to assist with difficult dissections for patient safety.

Change in quality of life between primary laparoscopic cholecystectomy and laparoscopic cholecystectomy after percutaneous transhepatic gall bladder drainage

One of the most important reasons for avoiding percutaneous transhepatic gall bladder drainage (PTGBD) is the deterioration of quality of life (QOL). However, there is no study comparing the QOL between primary laparoscopic cholecystectomy (LC) and LC following PTGBD.Among the LC patients, 69 non-PTGBD patients and 21 PTGBD patients were included after excluding the patients with malignant disease or who needed additional common bile duct procedures. Clinicopathologic characteristics and surgical outcomes were compared. QOL was evaluated with questionnaire EORCT-C30 before and after surgery.The included patients comprised 69 non-PTGBD and 21 PTGBD patients. The PTGBD group include older and higher morbid patients. PTGBD group needed longer operation times than the non-PTGBD group (72.4±34.7 minute vs 52.8±22.0 minute, P = .022) Regarding the overall incidence of complication, the PTGBD group had a significantly higher complication rate than the non-PTGBD group (38.1% vs 10.1%, P = .003) However, there was no significant difference in severe complication). Regarding the QOL, both the functional and global health scales were improved following surgery compared to the preoperative evaluation. Comparative analysis of the 2 groups showed no significant difference in global heath scale either preoperative or postoperatively, while the functional scale and emotional scale were better in the PTGBD group compared to the non-PTGBD group. Regarding the symptom scale, postoperative dyspnea and perioperative diarrhea were better in the PTGBD group.LC following an interval from earlier PTGBD that targets acute cholecystitis or complicated GB had little to no impact on QOL when compared to standard LC.

Incremental net benefit of cholecystectomy compared with alternative treatments in people with gallstones or cholecystitis: a systematic review and meta-analysis of cost–utility studies

Introduction

Cholecystectomy is a standard treatment in the management of symptomatic gallstone disease. Current literature has contradicting views on the cost-effectiveness of different cholecystectomy treatments. We have conducted a systematic reappraisal of literature concerning the cost-effectiveness of cholecystectomy in management of gallstone disease.

Methods

We systematically searched for economic evaluation studies from PubMed, Embase and Scopus for eligible studies from inception up to July 2020. We pooled the incremental net benefit (INB) with a 95% CI using a random-effects model. We assessed the heterogeneity using the Cochrane-Q test, I2 statistic. We have used the modified economic evaluation bias (ECOBIAS) checklist for quality assessment of the selected studies. We assessed the possibility of publication bias using a funnel plot and Egger’s test.

Results

We have selected 28 studies for systematic review from a search that retrieved 8710 studies. Among them, seven studies were eligible for meta-analysis, all from high-income countries (HIC). Studies mainly reported comparisons between surgical treatments, but non-surgical gallstone disease management studies were limited. The early laparoscopic cholecystectomy (ELC) was significantly more cost-effective compared with the delayed laparoscopic cholecystectomy (DLC) with an INB of US$1221 (US$187 to US$2255) but with high heterogeneity (I2=73.32%). The subgroup and sensitivity analysis also supported that ELC is the most cost-effective option for managing gallstone disease or cholecystitis.

Conclusion

ELC is more cost-effective than DLC in the treatment of gallstone disease or cholecystitis in HICs. There was insufficient literature on comparison with other treatment options, such as conservative management and limited evidence from other economies.

Effect of the COVID-19 Pandemic on the Management of Acute Cholecystitis and Assessment of the Crisis Approach: A Multicenter Experience in Egypt

INTRODUCTION

The covid-19 pandemic has had a drastic impact on all medical services. Acute cholecystitis is a serious condition that accounts for a considerable percentage of general surgical acute admissions. Therefore, the Royal College of Surgeons' Commissioning guidance' recommended urgent admission to secondary care and early cholecystectomy. During the first wave of hospital admissions associated with COVID-19, most guidelines recommended conservative treatment in order to limit the admission rates and free up spaces for COVID-19-infected patients. However, reviews of this approach have not been widely done to assess the results and, in turn, planning our future management approach when future pressures on in-patient admissions are inevitable.

METHODS

Our study included all acute cholecystitis patients who needed surgical intervention in one Centre in the UK over three distinct periods (pre-COVID-19, during the first lockdown, and lockdown ease). Comparison between these groups were done regarding intraoperative and postoperative results.

RESULTS

The conservative management led to a high rate of readmission. Moreover, delayed cholecystectomy was associated with increased operative difficulties such as extensive adhesions, intraoperative blood loss, and/or complicated gall bladder pathologies such as perforated or gangrenous gall bladder (29.9%, 16.7%, and 24.8%, respectively). The resulting postoperative complications of surgical and nonsurgical resulted in a longer hospital stay (13.5 d).

CONCLUSION

The crisis approach for acute cholecystitis management failed to deliver the hoped outcome. Instead, it backfired and did the exact opposite, leading to longer hospital stays and extra burden to the patient and the healthcare system.

The impact of COVID-19 on emergency cholecystectomy

BACKGROUNDS

The impact of the SARS-CoV-2 virus (COVID-19) upon the delivery of surgical services in Australia has not been well characterized, other than restrictions to elective surgery due to government directive-related cancellations. Using emergency cholecystectomy as a representative operation, this study aimed to investigate the impact of COVID-19 on emergency general surgery in Australia in relation to in-hours versus after-hours operating.

METHODS

A retrospective analysis was conducted of medical records for patients admitted with cholecystitis or biliary colic between 1 March 2019 and 28 February 2021 at Frankston Hospital, Australia. Patient demographics, admission data, imaging findings, operative and post-operative data were compared between pre-COVID-19 and COVID-19 periods. Variables were compared using the Wilcoxon-Mann-Whitney, Chi Squared or Fishers exact test.

RESULTS

During the COVID-19 period, emergency cholecystectomy was performed for a greater proportion of patients presenting with cholecystitis or biliary colic (93.5% versus 77.7%, p < 0.01). Despite this, there was concomitant reduction in after-hours cholecystectomy from 14.4% to 7.5% (p = 0.04). Patients requiring after-hours surgery during the COVID-19 period had more features of sepsis (23% more tachypnoeic, 18% more hypotensive), and were more likely to have certain features of cholecystitis on imaging (45% more likely to have pericholecystic fluid).

CONCLUSION

Following elective surgery cancellations during the COVID-19 period, an increase was seen in the proportion of patients presenting with gallstone disease who were managed with emergency cholecystectomy due to improved theatre access. Concurrently, there was a decrease in the requirement for surgery to be performed after-hours.

A nationwide analysis of gallbladder surgery in England between 2000 and 2019

BACKGROUND

There are no reports on nationwide trends in subtotal cholecystectomy (STC) and cholecystostomy in England. We hypothesized that, as in the United States, a substantial increase in the utilization of these surgical procedures, over time, may be observed. We aimed to generate a reliable report on 4 of the most common gallbladder surgical procedures in England to allow cross-procedure comparisons and highlight significant changes in the management of benign gallbladder disease over time.

METHODS

We obtained data from NHS Digital and extracted population estimates from the Office of National Statistics. We examined the trends in the use of STC, cholecystostomy, cholecystolithotomy and total cholecystectomy (TC) between 2000 and 2019.

RESULTS

Of the 1,234,319 gallbladder surgeries performed, TC accounted for 96.8% (n = 1,194,786) and the other 3 surgeries for 3.2% (n = 39,533). The total number of gallbladder surgeries performed annually increased by 80.4% from 2000 to 2019. We detected increases in the counts of cholecystostomies by 723.1% (n = 290 in 2000 vs n = 2,387 in 2019) and STCs by 716.6% (n = 217 in 2000 vs n = 1,772 in 2019). Consequently, there was a decrease in the ratio of TC to STC (180:1 in 2000 vs 38:1 in 2019). A similar decrease was observed in the ratio of cholecystectomy to cholecystostomy (135:1 in 2000 vs 29:1 in 2019).

CONCLUSION

Increased utilization of STC and cholecystostomy was detected in England. These findings highlight the importance of regular monitoring of nationwide trends in gallbladder surgery and the associated clinical outcomes.

Variation in the rates of emergency surgery amongst emergency admissions to hospital for common acute conditions

Background

This paper assesses variation in rates of emergency surgery (ES) amongst emergency admissions to hospital in patients with acute appendicitis, cholelithiasis, diverticular disease, abdominal wall hernia, and intestinal obstruction.

Methods

Records of emergency admissions between 1 April 2010 and 31 December 2019 for the five conditions were extracted from Hospital Episode Statistics for 136 acute National Health Service (NHS) trusts in England. Patients who had ES were identified using Office of Population Censuses and Surveys (OPCS) procedure codes, selected by consensus of a clinical panel. The differences in ES rates according to patient characteristics, and unexplained variations across NHS trusts were estimated by multilevel logistic regression, adjusting for year of emergency admission, age, sex, ethnicity, diagnostic subcategories, index of multiple deprivation, number of co-morbidities, and frailty.

Results

The cohort sizes ranged from 107 325 (hernia) to 268 253 (appendicitis) patients, and the proportion of patients who received ES from 11.0 per cent (diverticular disease) to 92.3 per cent (appendicitis). Older patients were generally less likely to receive ES, with adjusted odds ratios (ORs) of ES for those aged 75–79 versus those aged 45–49 years: 0.34 (appendicitis), 0.49 (cholelithiasis), 0.87 (hernia), and 0.91 (intestinal obstruction). Patients with diverticular disease aged 75–79 were more likely to receive ES than those aged 45–49 (OR 1.40). Variation in ES rates across NHS trusts remained after case mix adjustment and was greatest for cholelithiasis (trust median 18 per cent, 10th to 90th centile 7–35 per cent).

Conclusion

For patients presenting as emergency hospital admissions with common acute conditions, variation in ES rates between NHS trusts remained after adjustment for demographic and clinical characteristics. Age was strongly associated with the likelihood of ES receipt for some procedures.

Outcomes Following an Index Emergency Admission With Cholecystitis: A National Cohort Study

OBJECTIVE

The objective of this study was to evaluate the differences between patients who undergo cholecystectomy following index admission for cholecystitis, and those who are managed nonoperatively.

SUMMARY BACKGROUND DATA

Index emergency cholecystectomy following acute cholecystitis is widely recommended by national guidelines, but its effect on clinical outcomes remains uncertain.

METHODS

Data collected routinely from the Hospital Episode Statistics database (all admissions to National Health Service organizations in England and Wales) were extracted between April 1, 2002 and March 31, 2015. Analyses were limited to patients aged over 18 years with a primary diagnosis of cholecystitis. Exclusions included records with missing or invalid datasets, patients who had previously undergone a cholecystectomy, patients who had died without a cholecystectomy, and those undergoing cholecystectomy for malignancy, pancreatitis, or choledocholithiasis. Patients were grouped as either "no cholecystectomy" where they had never undergone a cholecystectomy following discharge, or "cholecystectomy." The latter group was then subdivided as "emergency cholecystectomy" when cholecystectomy was performed during their index emergency admission, or "interval cholecystectomy" when a cholecystectomy was performed within 12 months following a subsequent (emergency or elective) admission. Propensity Score Matching was used to match emergency and interval cholecystectomy groups. Main outcome measures included 1) One-year total length of hospital stay due to biliary causes following an index emergency admission with cholecystitis. 2) One-year mortality; defined as death occurring within 1 year following the index emergency admission with acute cholecystitis.

RESULTS

Of the 99,139 patients admitted as an emergency with acute cholecystitis, 51.1% (47,626) did not undergo a cholecystectomy within 1 year of index admission. These patients were older, with more comorbidities (Charlson Comorbidity Score ≥ 5 in 23.5% vs. 8.1%, P < 0.001) when compared to patients who did have a cholecystectomy. While all-cause 1-year mortality was higher in the nonoperated versus the operated group (12.2% vs. 2.0%, P < 0.001), gallbladder-related deaths were significantly lower than all other causes of death in the non-operated group (3.3% vs. 8.9%, P < 0.001). Following matching, 1-year total hospital admission time was significantly higher following emergency compared with interval cholecystectomy (17.7 d vs. 13 d, P < 0.001).

CONCLUSIONS

Over 50% of patients in England did not undergo cholecystectomy following index admission for acute cholecystitis. Mortality was higher in the nonoperated group, which was mostly due to non-gallbladder pathologies but total hospital admission time for biliary causes was lower over 12 months. Increasing the numbers of emergency cholecystectomy may risk over-treating patients with acute cholecystitis and increasing their time spent admitted to hospital.

Time to abandon the old dictum of delayed laparoscopic cholecystectomy after acute cholecystitis has settled in Caribbean practice

Although laparoscopic cholecystectomy is the gold standard treatment for acute cholecystitis, many Caribbean surgeons are reluctant to operate during the acute attack. We collected data for all consecutive patients who underwent laparoscopic cholecystectomy for acute cholecystitis from January 1 to 31 December 2018. Delayed cholecystectomy was done >6 weeks after acute cholecystitis settled. We compared data between early and delayed groups. Delayed laparoscopic cholecystectomy was performed in 54 patients, and 42 had early laparoscopic cholecystectomy. Delayed surgery resulted in significantly more complications requiring readmission (39% vs 0), longer operations (2.27 vs 0.94 h) and lengthier post-operative hospitalisation (1.84 vs 1.1 days). Caribbean hospitals should abandon the practice of delayed surgery after cholecystitis has settled. Early laparoscopic cholecystectomy would be financially advantageous for our institutions, and it would save patients recurrent attacks of gallstone disease.

Early laparoscopic cholecystectomy for acute cholecystitis is safe regardless of timing

PURPOSE

The optimal timing for laparoscopic cholecystectomy for acute cholecystitis (AC) has not been resolved. In the revised Tokyo Guidelines from 2018 (TG18), early laparoscopic cholecystectomy (ELC) is recommended regardless of the duration of symptoms. The aim of this study was to evaluate the safety of ELC compared with delayed laparoscopic cholecystectomy (DLC) for AC. In addition, we assessed the perioperative outcomes after ELC based on duration of symptoms.

METHODS

A retrospective cohort study of patients operated for acute calculous cholecystitis from January 1, 2017, to June 30, 2018, at Copenhagen University Hospital, Herlev. ELC was divided into three subgroups based on the duration of symptoms from onset to operation, ≤ 72 h, > 72-120 h, > 120 h.

RESULTS

Two hundred twenty-two patients underwent ELC and 26 (10.5%) patients underwent DLC. We found no difference in mortality, morbidity, conversion rate, or bile duct injuries between DLC and ELC or in the subgroups based on duration of symptoms. We found significantly longer total hospital length of stay for patients with symptoms > 72 h (4.1-5.6 days) compared to ≤ 72 h (3.1 days) and the longest in DLC (9.9 days). Twenty-three percent of DLC needed an emergency operation in the waiting period with a high conversion rate (1/3).

CONCLUSION

ELC for AC even beyond 5 days of symptoms is safe and not associated with increased complications. The duration of symptoms in AC is not an independent predictor and should not influence the surgeonsmsdecision to perform an ELC. Delaying cholecystectomy has a high failure rate.

Ursodeoxycholic acid for the prevention of gallstone and subsequent cholecystectomy following gastric surgery: A systematic review and meta-analysis

BACKGROUND/PURPOSE

Patients who undergo gastric surgery are prone to form postsurgical gallstones. Debates still exist about the need for prevention and the selection of preventive methods. No studies had been reported comparing the efficacy of prophylactic ursodeoxycholic acid (UDCA) and prophylactic cholecystectomy (PC) for lowering postsurgical gallstone formation and subsequent cholecystectomy (SC) in patients who have undergone gastric surgery.

METHODS

We did a systematic review to identify studies from PUBMED, EMBASE, and the Cochrane database through 30 June 2020. We conducted direct and indirect comparisons of each prophylaxis using conventional and network meta-analysis. Studies with patients who have no history of cholecystectomy and who have not had preoperative gallstone were included.

RESULTS

The excellent preventive effects of PC and UDCA were demonstrated for gallstone formation (odds ratio [OR] 0.05, [95% CI 0.01, 0.22] and 0.20, [95% CI 0.16, 0.24], respectively) and the need for SC (OR 0.10, [95% CI 0.02, 0.57] and OR 0.22, [95% CI 0.14, 0.35], respectively) than control group. The UDCA group showed a tendency to generate more gallstones (OR 3.74, [95% CI 0.88, 15.82]) and a greater need for SC (OR 2.19, [95% CI 0.47-10.14]) than did the PC group without statistical significance.

CONCLUSIONS

Prophylaxis for gallstone formation may be needed for patients who undergo gastric surgery to reduce troublesome morbidities. Prophylactic UDCA seems to be a reasonable preventive method for postsurgical gallstone formation to ensure clinical benefit while reducing the burden of subsequent cholecystectomy for the patient as compared to a PC.

Timing of early laparoscopic cholecystectomy for acute calculous cholecystitis: a meta-analysis of randomized clinical trials

Background

Early cholecystectomy for acute cholecystitis has proved to reduce hospital length of stay but with no benefit in morbidity when compared to delayed surgery. However, in the literature, early timing refers to cholecystectomy performed up to 96 h of admission or up to 1 week of the onset of symptoms. Considering the natural history of acute cholecystitis, the analysis based on such a range of early timings may have missed a potential advantage that could be hypothesized with an early timing of cholecystectomy limited to the initial phase of the disease. The review aimed to explore the hypothesis that adopting immediate cholecystectomy performed within 24 h of admission as early timing could reduce post-operative complications when compared to delayed cholecystectomy.

Methods

The literature search was conducted based on the Patient Intervention Comparison Outcome Study (PICOS) strategy. Randomized trials comparing post-operative complication rate after early and delayed cholecystectomy for acute cholecystitis were included. Studies were grouped based on the timing of cholecystectomy. The hypothesis that immediate cholecystectomy performed within 24 h of admission could reduce post-operative complications was explored by comparing early timing of cholecystectomy performed within and 24 h of admission and early timing of cholecystectomy performed over 24 h of admission both to delayed timing of cholecystectomy within a sub-group analysis. The literature finding allowed the performance of a second analysis in which early timing of cholecystectomy did not refer to admission but to the onset of symptoms.

Results

Immediate cholecystectomy performed within 24 h of admission did not prove to reduce post-operative complications with relative risk (RR) of 1.89 and its 95% confidence interval (CI) [0.76; 4.71]. When the timing was based on the onset of symptoms, cholecystectomy performed within 72 h of symptoms was found to significantly reduce post-operative complications compared to delayed cholecystectomy with RR = 0.60 [95% CI 0.39;0.92].

Conclusion

The present study failed to confirm the hypothesis that immediate cholecystectomy performed within 24 h of admission may reduce post- operative complications unless surgery could be performed within 72 h of the onset of symptoms.

Anatomic Variation of the Cystic Artery: New Findings and Potential Implications

Purpose: To determine the anatomy of the cystic artery by dual-source CT, and correlate imaging findings with those patients who had laparoscopic cholecystectomy (LC). Materials and Methods: Following institutional review board approval, a total of 289 consecutive patients (204 men and 85 women) were evaluated with CT for abdominal pain, including 55 patients subsequently underwent LC. Location of the cystic artery termination, distance between the cystic artery origin and the gallbladder, and angle between the cystic artery and its parent artery were evaluated by two radiologists. The laparoscopic surgical video record (gold standard) was similarly evaluated by a surgeon. Results: A total of 256 cystic arteries in the 247 patients were included. Cystic artery terminations are predominately found in ventral Calot triangle plane (50.8%, type II). Cystic artery origin immediately adjacent to the gallbladder surface was seen in 11/256 (4.3%). Zero angle between the cystic artery and its parent artery was found in 17 of 256 cystic arteries (6.6%). The cystic arteries and the Calot triangle were depicted in 49 patients (95% confidence interval: 85%, 97%). For all 49 patients, CT imaging findings were consistent with surgical video records. No case involved vascular and biliary injury occurred. Conclusions: Given the large number of LC performed each year, better knowledge of anatomic variation of the cystic artery could potentially prevent arterial injury and bile duct injury, particularly for patients with unusual anatomy.

Outcomes of percutaneous cholecystostomy in elderly patients: a systematic review and meta-analysis

INTRODUCTION

Percutaneous cholecystostomy (PC) represents a management option to control sepsis in patients with acute cholecystitis, who are unable to tolerate surgery.

AIM

This review aimed to evaluate the outcomes of elderly patients treated with PC and compare it with emergent cholecystectomy.

MATERIAL AND METHODS

An electronic search of the Embase, Medline Web of Science, and Cochrane databases was performed. Percutaneous cholecystostomy was used as the reference group, and weighted mean differences (WMD) were calculated for the effect of PC on continuous variables, and pooled odds ratios (POR) were calculated for discrete variables.

RESULTS

There were 20 trials included in this review. Utilisation of PC was associated with significantly increased mortality (POR = 4.85; 95% CI: 1.02-7.30; p = 0.0001) and increased re-admission rates (POR = 2.95; 95% CI: 2.21-3.87; p < 0.0001).

CONCLUSIONS

This pooled analysis established that patients treated with PC appear to have increased mortality and readmission rates relative to those managed with cholecystectomy.

Days of symptoms and days of hospital admission before surgery do not influence the results of cholecystectomy in moderate acute calculous cholecystitis

BACKGROUND AND AIMS

Early cholecystectomy is the gold standard treatment for acute calculous cholecystitis (AC), although for grade II, many surgeons still prefer delayed cholecystectomy, to avoid surgical complications. The aim of this study is to analyze postoperative morbidity and mortality for Tokyo Guidelines grade II AC treated with cholecystectomy, taking in to account the days of symptoms and the days since hospital admission.

MATERIALS AND METHODS

Unicentre, retrospective study based on a prospective database. Patients with grade II AC treated with cholecystectomy were selected. Patients were analyzed according to Days of Symptoms (DS) and Days of Hospital Admission (DHA) until cholecystectomy. Patients were subdivided in: < 3 days, 3-5 days, >5 days. Univariant and multivariant analysis for morbidity and mortality. Categorical variables were compared using chi square or Fischer's exact test. Continuous variables were compared using the Mann Whitney U test. Level of statistical significance was set at p < 0.05.

RESULTS

998 patients with AC diagnoses were included; 567 with grade II AC; 368 treated with cholecystectomy. Nearly 90% were treated laparoscopically; 48.1% were operated the same day of emergency admission. For DS and DHA there were no statistical differences for severe postoperative complications, although a greater number of complications were detected in >5 DS (p: 0.32) and >5 DHA (p: 0.00). Statistically differences were found in DS for mortality (p:0.04). Postoperative length of stay was longer for >5 DHA cholecystectomies, (p > 0.05). No differences for hospital readmission.

CONCLUSION

Regardless of DS or DHA until cholecystectomy, do not exist statistically significant differences related to severe postoperative complications, length of stay or mortality.

Role of percutaneous cholecystostomy in all-comers with acute cholecystitis according to current guidelines in a general surgical unit

Acute calculous cholecystitis (ACC) is a very common complication of gallstone-related disease. Its currently recommended management changes according to severity of disease and fitness for surgery. The aim of this observational study is to assess the short- and long-term outcomes in all-comers admitted with diagnosis of ACC, treated according to 2013 Tokyo Guidelines (TG13). A retrospective analysis was conducted on a prospectively maintained database of 125 patients with diagnosis of ACC consecutively admitted between January 2017 and September 2019, subdivided in three groups according to TG13: percutaneous cholecystostomy (PC group), cholecystectomy (CH group), and conservative medical treatment (MT group). The primary end point was a composite of morbidity and/or mortality rates; the secondary end points were ACC recurrence, readmission, need for cholecystectomy rates and overall length of hospital stay (LOS). After a median follow-up of 639 days, overall morbidity rate was 20.8% and mortality rate was 6.4%. Death was directly related to AC during the index admission in two out of eight cases. There were no significant differences in primary end point according to the treatment group. Concerning secondary end points, ACC recurrence rate was not significantly different after PC (10.0%) or MT (9.1%); the readmission rates were significantly higher (p < 0.0001) in the MT group (48.5%) and in the PC group (25.0%) than in the CH group (5.8%); need for cholecystectomy rates was significantly higher (p < 0.0001) in the MT group (42.4%) than in the PC group (20.0%); median overall LOS was significantly higher in the PC (16 days) than in the MT (9 days) and than in the CH group (5 days). PC is an effective and safe rescue procedure in high-risk patients with ACC, representing a definitive treatment in 80% of cases of this specific subgroup.

Early versus delayed cholecystectomy for cholecystitis at high risk of operative difficulties: A propensity score-matching analysis

BACKGROUND

Numerous studies have demonstrated the superiority of early (EC) over delayed (DC) cholecystectomy for acute cholecystitis (AC). However, none have assessed the effect of operative difficulty when reporting on treatment outcomes.

METHODS

Outcomes of patients who underwent EC or DC between 2010 and 2019 were compared taking into account the operative difficulty evaluated by the Difficult Laparoscopic Cholecystectomy score (DiLC). For each patient, the DiLC score was retrospectively calculated and corresponded to the foreseeable operative difficulty measured on admission for AC. A propensity score was used to account for confounders. Primary endpoints were the length of stay (LOS) and the occurrence of a serious operative/post-operative event (SOE).

RESULTS

DC in patients with DiLC≥10 reduced the risk of SOE without increasing the LOS. Conversely, DC in patients with DiLC<10 increased the LOS without improving outcomes. Multivariate analysis found EC in patients with DiLC≥10 as the main independent predictor of SOE.

CONCLUSIONS

Provided prospective validation, DC for AC in patients with DiLC≥10 seems safer than EC and is not hospital-stay consuming.

Robotic Cholecystectomy Is a Safe Educational Alternative to Laparoscopic Cholecystectomy During General Surgical Training: A Pilot Study

OBJECTIVE

The role of robotic surgery in general surgery (GS) continues to expand. Several programs have integrated robotic-based simulators and models into surgical education; however, residents' robotic experience in the operating room is currently limited. We sought to assess the safety and feasibility of robotic cholecystectomy (RC) when independently performed by GS chief residents.

METHODS

From June 2016 to October 2018, RC and laparoscopic cholecystectomies (LC) performed independently by chief residents on a resident staff surgical service were prospectively included. Patient demographics, intraoperative variables, and postoperative complications were analyzed and compared between both cohorts.

RESULTS

A total of 20 RC and 70 LC were included. Patient characteristics, indications for surgery, and comorbidities were similar in both groups. RC was more likely to be performed electively (95% vs. 17.1%, p < 0.001). No difference in operative time, estimated blood loss, intraoperative bile duct injury, or conversion to open was observed. Patients undergoing LC had an overall longer mean length of hospital stay (2.7 days ± 2.1 vs. 0.8 days ± 0.4, p < 0.001); however, length of hospital stay was similar between RC and LC performed electively (p = 0.946). No difference in postoperative complications and 30-day readmission was observed.

CONCLUSIONS

RC can be safely and independently performed by GS residents with similar outcomes as LC. Efforts should be directed toward creating a platform to bridge competent simulator skills into safe performance in the operating suite. The integration of robotic training into the core GS curriculum should be encouraged.

Optimising the outcomes of index admission laparoscopic cholecystectomy and bile duct exploration for biliary emergencies: a service model

Aims

The rate of acute laparoscopic cholecystectomy remains low due to operational constraints. The purpose of this study is to evaluate a service model of index admission cholecystectomy with referral protocols, refined logistics and targeted job planning.

Methods

A prospectively maintained dataset was evaluated to determine the processes of care and outcomes of patients undergoing emergency biliary surgery. The lead author has maintained a 28 years prospective database capturing standard demographic data, intraoperative details including the difficulty of cholecystectomy as well as postoperative outcome parameters and follow up data.

Results

Over five thousand (5555) consecutive laparoscopic cholecystectomies were performed. Only patients undergoing emergency procedures (2399,43.2% of entire group) were analysed for this study. The median age was 52 years with 70% being female. The majority were admitted with biliary pain (34%), obstructive jaundice (26%) and acute cholecystitis (16%). 63% were referred by other surgeons. 80% underwent surgery within 5 days (40% within 24 h). Cholecystectomies were performed on scheduled lists (44%) or dedicated emergency lists (29%). Two thirds had suspected bile duct stones and 38.1% underwent bile duct exploration. The median operating time was 75 min, median hospital stay 7 days, conversion rate 0.8%, morbidity 8.9% and mortality rate 0.2%.

Conclusion

Index admission cholecystectomy for biliary emergencies can have low rates of morbidity and mortality. Timely referral and flexible theatre lists facilitate the service, optimising clinical results, number of biliary episodes, hospital stay and presentation to resolution intervals. Cost benefits and reduced interval readmissions need to be weighed against the length of hospital stay per episode.

Cholecystectomy for Complicated Gallbladder and Common Biliary Duct Stones: Current Surgical Management

Gallstone disease accounts for the vast majority of acute surgical admissions in the UK, with a major treatment being cholecystectomy. Practice varies significantly as to whether surgery is performed during the acute symptomatic phase, or after a period of recovery. Differences in practice relate to operative factors, patient factors, surgeon factors and hospital and trust wide policies. In this review we summarize recent evidence on management of gallstone disease, particularly with respect to whether cholecystectomy should occur during index presentation or following recovery. We highlight morbidity and mortality studies, cost, and patient reported outcomes. We speculate on barriers to change in service delivery. Finally, we propose potential solutions to optimize care.

Laparoscopic Cholecystectomy for Acute Cholecystitis: Is the Surgery Still Safe beyond the 7-Day Barrier?

BACKGROUND

The optimal timing for early laparoscopic cholecystectomy (ELC) in patients with acute calculous cholecystitis (ACC) is still controversial. The aim of this study was to assess the outcomes of ELC in patients with delayed presentation.

METHODS

Retrospective analysis of 381 patients who underwent ELC for ACC between January 2010 and September 2018. Included patients were classified into two groups according to the timing of surgery from the onset of symptoms: group 1 (G1) within the first 7 days and group 2 (G2) beyond 7 days.

RESULTS

There were no significant differences regarding conversion rate (G1 8.6% vs. G2 11.8%; p = 0.527), operative time (G1 100 min [75-120] vs. G2 120 min [71-150]; p = 0.060), bile duct injuries (G1 0.3% vs. G2 0%; p = 1), major postoperative complications (G1 11% vs. G2 5.9%; p = 0.557), reoperation rates (G1 1.4% vs. G2 0%; p = 1), length of stay (G1 4 days [3-7] vs. G2 5 days [3-7]; p = 0.539), readmissions (G1 3.7% vs. G2 5.9%; p = 0.633) and costs (G1 6035 € [3693-8330] vs. G2 7243 € [4921-11,336]; p = 0.395).

CONCLUSION

ELC may be considered for patients with ACC who can tolerate surgery with more than 1 week of symptom duration.

Predictive factors for developing acute cholangitis and/or cholecystitis in patients undergoing delayed cholecystectomy: A retrospective study

BACKGROUND

/Objective: We evaluated the risk of acute cholangitis and/or cholecystitis while waiting for cholecystectomy for gallstones.

METHODS

We retrospectively enrolled 168 patients who underwent cholecystectomy for gallstones after conservative therapy. We compared clinical data of 20 patients who developed acute cholangitis and/or cholecystitis while waiting for cholecystectomy (group A) with 148 patients who did not develop (group B). We investigated surgical outcomes and risk factors for developing acute cholangitis and/or cholecystitis.

RESULTS

Preoperatively, significant numbers of patients with previous history of acute grade II or III cholecystitis (55.0% vs 10.8%; p < 0.001) and biliary drainage (20.0% vs 2.0%; p = 0.004) were observed between groups A and B. White blood cell counts (13500/μL vs 8155/μL; p < 0.001) and C-reactive protein levels (12.6 vs 5.1 mg/dL; p < 0.001) were significantly higher in group A than in group B; albumin levels (3.2 vs 4.0 g/dL; p < 0.001) were significantly lower in group A. Gallbladder wall thickening (≥5 mm) (45.0% vs 18.9%; p = 0.018), incarcerated gallbladder neck stones (55.0% vs 22.3%; p = 0.005), and peri-gallbladder abscess (20.0% vs 1.4%; p = 0.002) were significantly more frequent in group A than in group B. A higher conversion rate to open surgery (20.0% vs 2.0%; p = 0.004), longer operation time (137 vs 102 min; p < 0.001), and higher incidence of intraoperative complications (10.0% vs 0%; p = 0.014) were observed in group A, compared with group B.

CONCLUSION

A history of severe cholecystitis may be a risk factor for acute cholangitis and/or cholecystitis in patients waiting for surgery; it may also contribute to increased surgical difficulty.

Does the Surgeon's Caseload Affect the Outcome in Laparoscopic Cholecystectomy for Acute Cholecystitis?

BACKGROUND

This study investigated how annual caseloads and the surgeon's previous experience influence the outcome in laparoscopic cholecystectomy (LCC) for acute cholecystitis.

METHODS

A total of 892 patients treated in Helsinki University Hospital in 2013-2016 were retrospectively analyzed. Surgeons were compared regarding volume-over 5 LCCs for acute cholecystitis a year versus 5 or fewer LCCs a year, and experience-attendings versus residents.

RESULTS

High-volume surgeons (n=14) operated faster than low-volume surgeons (n=62) (91 vs. 108 min, P<0.001). Examining only procedures with an attending present, high-volume attendings (n=7) converted less (14.9% vs. 32.0%, P<0.001) and operated faster (95 vs. 110 min, P<0.001) compared with low-volume attendings (n=41). The results of residents did not significantly differ from the results of attendings.

CONCLUSIONS

Attending surgeons, performing >5 LCCs for acute cholecystitis a year, have shorter operative times and lower conversion rates.

The incidence of symptomatic remnant gall bladder: a population study

BACKGROUND

Subtotal cholecystectomy is utilized in conditions of high risk to critical structures, like the common bile duct. However, the remnant gall bladder may become symptomatic and require a completion cholecystectomy for treatment. This second procedure can itself be a risk to critical structures. To establish the incidence of redo-cholecystectomy and identify risk factors that lead to subtotal cholecystectomy and repeat operation in a review of state-based practices for cholecystectomy.

METHODS

A search of state coding records relating to cholecystectomy from 1998 to 2016. Patients who were coded for cholecystectomy-related procedures on different dates were identified. Patients who underwent the procedures within 6 months were excluded to avoid acute post-operative complications and gall bladder malignancy.

RESULTS

210 719 cholecystectomies were performed. 1133 required repeat procedure. 616 were excluded, leaving 516 (0.25%) cholecystectomy patients requiring a second cholecystectomy. The subsequent operation was more likely to be an emergency procedure; involve transcystic bile duct exploration, adhesiolysis and require intensive care unit admission post-operatively. A repeat cholecystectomy was more likely to occur after having the primary procedure at a public hospital and when an intra-operative cholangiogram was not performed. Over the study period, the rate of repeat cholecystectomy increased from 0.02% to 0.6%. Incidentally, the rate of intra-operative cholangiogram during a primary cholecystectomy increased from 43% to 73%.

CONCLUSIONS

Repeat cholecystectomy is an uncommon procedure. A second cholecystectomy is a more complex and likely to require intensive care unit support. Referral to a tertiary hepatobiliary unit is recommended.

Patients with acute cholecystitis should be admitted to a surgical service

BACKGROUND

In bowel obstruction and biliary pancreatitis, patients receive more expedient surgical care when admitted to surgical compared with medical services. This has not been studied in acute cholecystitis.

METHODS

Retrospective analysis of clinical and cost data from July 2013 to September 2015 for patients with cholecystitis who underwent laparoscopic cholecystectomy in a tertiary care inpatient hospital. One hundred ninety lower-risk (Charlson-Deyo) patients were included. We assessed admitting service, length of stay (LOS), time from admission to surgery, time from surgery to discharge, number of imaging studies, and total cost.

RESULTS

Patients admitted to surgical (n = 106) versus medical (n = 84) service had shorter mean LOS (1.4 days vs. 2.6 days), shorter time from admission to surgery (0.4 days vs. 0.8 days), and shorter time from surgery to discharge (0.8 days vs. 1.1 days). Surgical service patients had fewer CT (38% vs. 56%) and magnetic resonance imaging (MRI) (5% vs. 16%) studies. Cholangiography (30% vs. 25%) and endoscopic retrograde cholangiopancreatography (ERCP) (3 vs. 8%) rates were similar. Surgical service patients had 39% lower median total costs (US $7787 vs. US $12572).

CONCLUSION

Nonsurgical admissions of patients with cholecystitis are common, even among lower-risk patients. Routine admission to the surgical service should decrease LOS, resource utilization and costs.

Safety and feasibility of prolonged versus early laparoscopic cholecystectomy for acute cholecystitis: a single-center retrospective study

Background

Laparoscopic cholecystectomy (LC) is the standard treatment for acute cholecystitis (AC), and it should be performed within 72 h of symptoms onset if possible. In many undesired situations, LC was performed beyond the golden 72 h. However, the safety and feasibility of prolonged LC (i.e., performed more than 72 h after symptoms onset) are largely unknown, and therefore were investigated in this study.

Methods

We retrospectively enrolled the adult patients who were diagnosed as AC and were treated with LC at the same admission between January 2015 and October 2018 in an emergency department of a tertiary academic medical center in China. The primary outcome was the rate and severity of adverse events, while the secondary outcomes were length of hospital stay and costs.

Results

Among the 104 qualified patients, 70 (67.3%) underwent prolonged LC and 34 (32.7%) underwent early LC (< 72 h of symptom onset). There were no differences between the two groups in mortality rate (none for both), conversion rates (prolonged LC 5.4%, and early LC 8.8%, P = 0.68), intraoperative and postoperative complications (prolonged LC 5.7% and early LC 2.9%, P ≥ 0.99), operation time (prolonged LC 193.5 min and early LC 198.0 min, P = 0.81), and operation costs (prolonged LC 8,700 Yuan, and early LC 8,500 Yuan, P = 0.86). However, the prolonged LC was associated with longer postoperative hospitalization (7.0 days versus 6.0 days, P = 0.03), longer total hospital stay (11.0 days versus 8.0 days, P < 0.01), and subsequently higher total costs (40,400 Yuan versus 31,100 Yuan, P < 0.01).

Conclusions

Prolonged LC is safe and feasible for patients with AC for having similar rates and severity of adverse events as early LC, but it is also associated with longer hospital stay and subsequently higher total cost.

Timing of early laparoscopic cholecystectomy for acute calculous cholecystitis revised: Protocol of a systematic review and meta-analysis of results

Background

Early laparoscopic cholecystectomy has been adopted as the treatment of choice for acute cholecystitis due to a shorter hospital length of stay and no increased morbidity when compared to delayed cholecystectomy. However, randomised studies and meta-analysis report a wide array of timings of early cholecystectomy, most of them set at 72 h following admission. Setting early cholecystectomy at 72 h or even later may influence analysis due to a shift towards a more balanced comparison. At this time, the rate of resolving acute cholecystitis and the rate of ongoing acute process because of failed conservative treatment could be not so different when compared to those operated with a delayed timing of 6-12 weeks. As a result, randomised comparison with such timing for early cholecystectomy and meta-analysis including such studies may have missed a possible advantage of an early cholecystectomy performed within 24 h of the admission, when conservative treatment failure has less potential effects on morbidity. This review will explore pooled data focused on randomised studies with a set timing of early cholecystectomy as a maximum of 24 h following admission, with the aim of verifying the hypothesis that cholecystectomy within 24 h may report a lower post-operative complication rate compared to a delayed intervention.

Methods

A systematic review of the literature will identify randomised clinical studies that compared early and delayed cholecystectomy. Pooled data from studies that settled the early intervention within 24 h from admission will be explored and compared in a sub-group analysis with pooled data of studies that settled early intervention as more than 24 h.

Discussion

This paper will not provide evidence strong enough to change the clinical practice, but in case the hypothesis is verified, it will invite to re-consider the timing of early cholecystectomy and might promote future clinical research focusing on an accurate definition of timing for early cholecystectomy for acute cholecystitis.

Drain in laparoscopic cholecystectomy in acute calculous cholecystitis: a randomised controlled study

BACKGROUND

There is paucity of evidence regarding the role of drain in laparoscopic cholecystectomy (LC) in acute calculous cholecystitis (ACC), and surgeons have placed the drains based on their experiences, not on evidence-based guidelines. This study aims to assess the value of drain in LC for ACC in a randomised controlled prospective study.

PATIENTS AND METHODS

All patients with mild and moderate ACC undergoing LC were assessed. Preoperatively, patients with choledocholithiasis, Mirizzi syndrome and biliary stent were excluded. Intraoperatively or postoperatively, patients with complications, partial cholecystectomies and malignancies were excluded. Patients were randomised using computer-generated random numbers into two groups at the end of cholecystectomy before closure. Requirement of radiologically guided (ultrasonography () or CT) percutaneous aspiration/drainage of symptomatic intra-abdominal collection or reoperation; continuation of parenteral antibiotics beyond 24 hours or change in antibiotics empirically or based on peritoneal fluid culture sensitivity; requirement of postoperative USG or CT scan based on postoperative clinical course; wound infection rates; postoperative pain using numeric rating scale at 6 and 24 hours; and the duration of hospital stay in both groups were noted.

RESULTS

Forty-two out of 50 consecutive patients were randomised into two equal groups. Pain score at 6 and 24 hours was less in patients without drain. All other complication rates and duration of stay were similar in both groups.

CONCLUSIONS

Drains should not be placed routinely after LC in ACC as it increases pain and does not help in detecting or decreasing complications.

Acute cholecystitis or simple biliary colic after an emergency presentation: why it matters

BACKGROUND

Laparoscopic cholecystectomy (LC) is often performed during the index admission after emergency presentation for acute biliary pain. Many patients have acute cholecystitis (AC) that may increase operative difficulty and complications. Our primary aim was to assess the validity of Tokyo Guidelines (TG18) for diagnosing AC by comparison with the admitting team diagnosis, operative findings and histopathology. The secondary aim was to assess outcomes after same-admission or delayed LC.

METHODS

Retrospective analysis of patients who underwent LC after presenting to a tertiary hospital emergency department over a 12-month period was conducted.

RESULTS

A total of 139 patients underwent LC with no mortality or bile duct injury. A diagnosis of AC made by the admitting surgical team had sensitivity of 84% and specificity of 57%. The TG18 diagnosis had sensitivity of 84% and specificity of 53%. A diagnosis of AC by the admitting surgical team correlated well with TG18 criteria diagnosis. There was poor correlation between clinical and histopathological diagnoses. Nine percent of patients had complications and 4% required conversion to open procedure. Patients with a clinical diagnosis of AC had longer post-operative length of stay and more complications compared with those who had non-AC diagnosis. There was no difference in outcomes between same-admission LC or delayed LC.

CONCLUSION

TG18 diagnosis of AC does not improve accuracy of diagnosis or predictability of a poor outcome over the admitting surgical team diagnosis. Same-admission LC for patients with AC is associated with similar outcomes compared to those who undergo delayed LC.

Effectiveness of a quality improvement collaborative in reducing time to surgery for patients requiring emergency cholecystectomy

Background

Acute gallstone disease is a high-volume emergency general surgery presentation with wide variations in the quality of care provided across the UK. This controlled cohort evaluation assessed whether participation in a quality improvement collaborative approach reduced time to surgery for patients with acute gallstone disease to fewer than 8 days from presentation, in line with national guidance.

Methods

Patients admitted to hospital with acute biliary conditions in England and Wales between 1 April 2014 and 31 December 2017 were identified from Hospital Episode Statistics data. Time series of quarterly activity were produced for the Cholecystectomy Quality Improvement Collaborative (Chole-QuIC) and all other acute National Health Service hospitals (control group). A negative binomial regression model was used to compare the proportion of patients having surgery within 8 days in the baseline and intervention periods.

Results

Of 13 sites invited to join Chole-QuIC, 12 participated throughout the collaborative, which ran from October 2016 to January 2018. Of 7944 admissions, 1160 patients had a cholecystectomy within 8 days of admission, a significant improvement (P < 0·050) from baseline performance. This represented a relative change of 1·56 (95 per cent c.i. 1·38 to 1·75), compared with 1·08 for the control group. At the individual site level, eight of the 12 Chole-QuIC sites showed a significant improvement (P < 0·050), with four sites increasing their 8-day surgery rate to over 20 per cent of all emergency admissions, well above the mean of 15·3 per cent for control hospitals.

Conclusion

A surgeon-led quality improvement collaborative approach improved care for patients requiring emergency cholecystectomy.

Fluorescent Cholangiography in Laparoscopic Cholecystectomy: An Updated Canadian Experience

Background. Laparoscopic cholecystectomy (LC) is one of the most common general surgery procedures in Canada with approximately 100 000 cases performed per year. Bile duct injury remains a morbid complication with an incidence rate of 0.3% to 0.5%. Indocyanine green (ICG) fluorescent cholangiography is a noninvasive technology aiding in real-time identification of biliary structures for safe dissection within Calot's triangle. The objectives were to provide an update to our initial experience with ICG aiding in the identification of biliary structures and ensuring that no adverse patient reactions occurred with ICG administration. Methods. Prospective case series from 2016 to 2018 for elective LC with ICG technology performed at a single academic teaching institution. Patient demographics, indications for operation, biliary structures visualized, amount of ICG used, operative times, and complications were recorded. Results. One hundred eight cases were included for review. The cystic duct, common hepatic duct, and common bile duct were identified with ICG in 90%, 48%, and 84% of cases, respectively. ICG simultaneously visualized at least 2 of 3 biliary structures 83.4% of the time. Only 1 biliary structure was identified in 10% of cases. No biliary structures were identified in 6% of cases. Mean initial ICG dose given was 1.65 mL. No adverse patient reactions to ICG were noted. Conclusions. This updated series illustrates that administration of ICG enhances visualization of the biliary system during outpatient LC. ICG is safe and its application should be further studied in early LC for acute cholecystitis.
