Routine laparoscopic cholecystectomy after endoscopic sphincterotomy for choledocholithiasis in octogenarians: is it worth the risk?

Prophylactic cholecystectomy offers best outcomes following ERCP clearance of common bile duct stones: a meta-analysis

BACKGROUND

Symptomatic calculus biliary disease is common with associated morbidity and occasional mortality, further confounded when there is concomitant common bile duct (CBD) stones. Choledocholithiasis and clearance of the duct reduces recurrent cholangitis, but the question is whether after clearance of the CBD if there is a need to perform a cholecystectomy. This meta-analysis evaluated outcomes in patients undergoing ERCP with or without sphincterotomy to determine if cholecystectomy post-ERCP clearance offers optimal outcomes over a wait-and-see approach.

METHODS

A Prospero registered meta-analysis of the literature using PRISMA guidelines incorporating articles related to ERCP, choledocholithiasis, cholangitis and cholecystectomy was undertaken for papers published between 1st January 1991 and 31st May 2021. Existing research that demonstrates outcomes of ERCP with no cholecystectomy versus ERCP and cholecystectomy was reviewed to determine the related key events, complications and mortality of leaving the gallbladder in situ and removing it. Odds ratios (OR) were calculated using Review Manager Version 5.4 and meta-analyses performed using OR using fixed-effect (or random-effect) models, depending on the heterogeneity of studies.

RESULTS

13 studies (n = 2598), published between 2002 and 2019, were included in this meta-analysis, 6 retrospective, 2 propensity score-matched retrospective studies, 3 prospective studies and 2 randomised control trials from a total of 11 countries. There were 1433 in the no cholecystectomy cohort (55.2%) and 1165 in the prophylactic cholecystectomy (44.8%) cohort. Cholecystectomy resulted in a decreased risk of cholecystitis (OR = 0.15; CI 0.07-0.36; p < 0.0001), cholangitis (OR = 0.51; CI 0.26-1.00; p = 0.05) and mortality (OR = 0.38; CI 0.16-0.9; p = 0.03). In addition, prophylactic cholecystectomy resulted in a significant reduction in biliary events, biliary pain and pancreatitis.

CONCLUSIONS

In patients undergoing CBD clearance, consideration should be given to performing prophylactic cholecystectomy to optimise outcomes.

Early versus delayed laparoscopic cholecystectomy after endoscopic retrograde cholangiopancreatography: A meta-analysis

PURPOSES

Patients with cholecysto- and choledocholithiasis usually undergo endoscopic retrograde cholangiopancreatography (ERCP)/-endoscopic sphincterotomy followed by laparoscopic cholecystectomy (LC). However, differences in the timing of LC after the ERCP may alter the post-operative outcomes. The aim of this study was to compare the effect of early (≤3 days) or delayed LC (>3 days) following ERCP on the post-operative outcomes.

METHODS

A comprehensive search of the 3 databases PubMed, EMBASE and the Cochrane Library was performed. Articles related to LC at different time-points after ERCP were retrieved. Dichotomous and continuous outcomes were analyzed by risk ratio (RR) and mean difference, and RevMan was used to analyze each group.

RESULTS

A total of 7 studies, including 5 randomized controlled studies and 2 retrospective studies, involved a total of 711 patients. There were 332 patients in early LC group and 379 in delayed LC group. The conversion rate was lower in the early LC group compared to the delayed LC group (RR 0.38, 95% confident interval 0.19 to 0.74, P = .005, I2 = 0%). Early LC resulted in a shorter operation time (RR -6.2, 95% CI -27.2 to -5.2, P = .004, I2 = 97%) and fewer complications (RR 0.48, 95% CI 0.29 to 0.79, P = .004, I2 = 17%). Subgroup analysis found that there were no significant differences in the conversion rate (RR 0.61, 95% CI 0.25 to 1.45, P = .26, I2 = 0%) or complications between the early LC group and the delayed group who underwent LC after 1 month.

CONCLUSION

Early LC after ERCP is the preferred treatment for patients with concurrent cholecysto- and choledocholithiasis due to improved clinical outcomes as compared to those who undergo delayed LC.

The role of cholecystectomy following endoscopic sphincterotomy and bile duct stone removal

INTRODUCTION

Choledocholithiasis is common, with patients usually treated with endoscopic retrograde cholangiopancreatography (ERCP) and subsequent cholecystectomy to remove the presumed source of common bile duct (CBD) stones. However, previous investigations into the management of patients following ERCP have focused on recurrent CBD stones, negating the risks of cholecystectomy. This article appraises the role of cholecystectomy following successful endoscopic clearance of bile duct stones.

METHODS

Patients undergoing ERCP and CBD clearance for choledocholithiasis at St James's University Hospital January 2015-December 2018 were included. Patients were divided into those who received cholecystectomy and those managed non-operatively. Readmissions, operative morbidity, mortality and treatment costs were investigated.

RESULTS

Eight hundred and forty-four patients received ERCP and CBD clearance with 3.9 years follow-up. Two hundred and nine patients underwent cholecystectomy with 15% requiring complex surgery. Three hundred and seventy-three patients were non-operatively managed. Unplanned readmissions occurred in 15% following ERCP, mostly within two years. There was no difference in readmissions between the two groups. Accounting for the entire patient pathway, non-operative management was less expensive.

CONCLUSIONS

The majority of patients do not require readmission following ERCP for CBD stones, and cholecystectomy did not reduce the risk of readmission. Few patients have recurrent CBD stones, but complex biliary surgery is frequently required. Routine cholecystectomy following ERCP needs to be re-evaluated and a more stratified approach to future risk developed.

Is early laparoscopic cholecystectomy after clearance of common bile duct stones by endoscopic retrograde cholangiopancreatography superior?: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

With medical advancement, common bile duct stones were treated by endoscopic retrograde cholangiopancreatography (ERCP), considered the standard treatment. However, ERCP might induce complications including pancreatitis and cholecystitis that could affect a subsequent laparoscopic cholecystectomy (LC), leading to conversion to open cholecystectomy perioperative complications. It is not yet known whether or not the time interval between ERCP and LC plays a role in increasing conversion rate and complications. Bides, in the traditional sense, after ERCP, for avoiding edema performing LC was several weeks later. Even no one study could definite whether early laparoscopic cholecystectomy after ERCP affected the prognosis or not clearly.

OBJECTIVE

Comparing some different surgical timings of LC after ERCP.

METHOD

Searching databases consist of all kinds of searching tools, such as Medline, Cochrane Library, Embase, PubMed, etc. All the included studies should meet the demands of this meta-analysis. In all interest outcomes below, we took full advantage of RevMan5 and WinBUGS to assess; the main measure was odds ratio (OR) with 95% confidence. Moreover, considering the inconsistency of the specific time points in different studies, we set a subgroup to analyze the timing of LC after ERCP. For this part, Bayesian network meta-analysis was done with WinBUGS.

RESULT

In the pool of conversion rate, the result suggested that the early LC group was equal compared with late LC (OR = 0.68, I2 = 0%, P = .23). Besides, regarding morbidity, there was no significant difference between the 2 groups (OR = 0.74, I2 = 0%, P = .26). However, early LC, especially for laparoscopic-endoscopic rendezvous that belonged to performing LC within 24 hours could reduce the post-ERCP pancreatitis (OR = 0.16, I2 = 29%, P = .0003). Considering early LC included a wide time and was not precise enough, we set a subgroup by Bayesian network, and the result suggested that performing LC during 24 to 72 hours was the lowest conversion rate (rank 1: 0%).

CONCLUSION

In the present study, LC within 24 to 72 hours conferred advantages in terms of the conversion rate, with no recurrence of acute cholecystitis episodes.

Common bile duct stones management: A network meta-analysis

BACKGROUND

Timely management is critical for treating symptomatic common bile duct (CBD) stones; however, a single optimal management strategy has yet to be defined in the acute care setting. Consequently, this systematic review and network meta-analysis, comparing one-stage (CBD exploration or intraoperative endoscopic retrograde cholangiopancreatography [ERCP] with simultaneous cholecystectomy) and two-stage (precholecystectomy or postcholecystectomy ERCP) procedures, was undertaken with the main outcomes of interest being postprocedural complications and hospital length of stay (LOS).

METHODS

PubMed, SCOPUS, MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were methodically queried for articles from 2010 to 2021. The search terms were a combination of medical subject headings terms and the subsequent terms: gallstone; common bile duct (stone); choledocholithiasis; cholecystitis; endoscopic retrograde cholangiography/ERCP; common bile duct exploration; intraoperative, preoperative, perioperative, and postoperative endoscopic retrograde cholangiography; stone extraction; and one-stage and two-stage procedure. Studies that compared two procedures or more were included, whereas studies not recording complications (bile leak, hemorrhage, pancreatitis, perforation, intra-abdominal infections, and other infections) or LOS were excluded. A network meta-analysis was conducted to compare the four different approaches for managing CBD stones.

RESULTS

A total of 16 studies (8,644 participants) addressing the LOS and 41 studies (19,756 participants) addressing postprocedural complications were included in the analysis. The one-stage approaches were associated with a decrease in LOS compared with the two-stage approaches. Common bile duct exploration demonstrated a lower overall risk of complications compared with preoperative ERCP, but there were no differences in the overall risk of complications in the remaining comparisons. However, differences in specific postprocedural complications were detected between the four different approaches managing CBD stones.

CONCLUSION

This network meta-analysis suggests that both laparoscopic CBD exploration and intraoperative ERCP have equally good outcomes and provide a preferable single-anesthesia patient pathway with a shorter overall length of hospital stay compared with the two-stage approaches.

National clinical practice guidelines for the treatment of symptomatic gallstone disease: 2021 recommendations from the Danish Surgical Society

BACKGROUND AND OBJECTIVE

Gallstones are highly prevalent, and more than 9000 cholecystectomies are performed annually in Denmark. The aim of this guideline was to improve the clinical course of patients with gallstone disease including a subgroup of high-risk patients. Outcomes included reduction of complications, readmissions, and need for additional interventions in patients with uncomplicated gallstone disease, acute cholecystitis, and common bile duct stones (CBDS).

METHODS

An interdisciplinary group of clinicians developed the guideline according to the GRADE methodology. Randomized controlled trials (RCTs) were primarily included. Non-RCTs were included if RCTs could not answer the clinical questions. Recommendations were strong or weak depending on effect estimates, quality of evidence, and patient preferences.

RESULTS

For patients with acute cholecystitis, acute laparoscopic cholecystectomy is recommended (16 RCTs, strong recommendation). Gallbladder drainage may be used as an interval procedure before a delayed laparoscopic cholecystectomy in patients with temporary contraindications to surgery and severe acute cholecystitis (1 RCT and 1 non-RCT, weak recommendation). High-risk patients are suggested to undergo acute laparoscopic cholecystectomy instead of drainage (1 RCT and 1 non-RCT, weak recommendation). For patients with CBDS, a one-step procedure with simultaneous laparoscopic cholecystectomy and CBDS removal by laparoscopy or endoscopy is recommended (22 RCTs, strong recommendation). In high-risk patients with CBDS, laparoscopic cholecystectomy is suggested to be included in the treatment (6 RCTs, weak recommendation). For diagnosis of CBDS, the use of magnetic resonance imaging or endoscopic ultrasound prior to surgical treatment is recommended (8 RCTs, strong recommendation). For patients with uncomplicated symptomatic gallstone disease, observation is suggested as an alternative to laparoscopic cholecystectomy (2 RCTs, weak recommendation).

CONCLUSIONS

Seven recommendations, four weak and three strong, for treating patients with symptomatic gallstone disease were developed. Studies for treatment of high-risk patients are few and more are needed.

Which octogenarian patients are at higher risk after cholecystectomy for symptomatic gallstone disease? A single center cohort study

BACKGROUND

Incidence of gallstones in those aged ≥ 80 years is as high as 38%-53%. The decision-making process to select those oldest old patients who could benefit from cholecystectomy is challenging.

AIM

To assess the risk of morbidity of the “oldest-old” patients treated with cholecystectomy in order to provide useful data that could help surgeons in the decision-making process leading to surgery in this population.

METHODS

A retrospective study was conducted between 2010 and 2019. Perioperative variables were collected and compared between patients who had postoperative complications. A model was created and tested to predict severe postoperative morbidity.

RESULTS

The 269 patients were included in the study (193 complicated). The 9.7% of complications were grade 3 or 4 according to the Clavien-Dindo classification. Bilirubin levels were lower in patients who did not have any postoperative complications. American Society of Anesthesiologists scale 4 patients, performing a choledocholithotomy and bilirubin levels were associated with Clavien-Dindo > 2 complications (P < 0.001). The decision curve analysis showed that the proposed model had a higher net benefit than the treating all/none options between threshold probabilities of 11% and 32% of developing a severe complication.

CONCLUSION

Patients with American Society of Anesthesiologists scale 4, higher level of bilirubin and need of choledocholithotomy are at the highest risk of a severely complicated postoperative course. Alternative endoscopic or percutaneous treatments should be considered in this subgroup of octogenarians.

Long-term mortality and intestinal obstruction after laparoscopic cholecystectomy: A systematic review and meta-analysis

BACKGROUND

Long-term outcomes of cholecystectomy are largely unknown though it is a common procedure in general surgery. We aimed to investigate the long-term mortality rate and incidence of intestinal obstruction after laparoscopic cholecystectomy.

MATERIALS AND METHODS

This systematic review and meta-analysis was reported according to the PRISMA 2020 and AMSTAR guidelines. A protocol was registered on PROSPERO (CRD42020178906). The databases PubMed, EMBASE, and Cochrane CENTRAL were last searched on February 9, 2022 for original studies on long-term complications with n > 40 and follow-up ≥ 6 months. Outcomes were long-term mortality and incidence of intestinal obstruction, and meta-analyses were conducted. Risk of bias was assessed with Newcastle-Ottawa Scale and Cochrane "Risk of bias"-tool according to study design.

RESULTS

We included 41 studies that reported long-term follow-up on 1,000,534 patients. Of these, 38 studies reported on mortality (514,242 patients) that ranged from 0 to 32%. Meta-analysis estimated a long-term mortality rate of 2.0% (95% CI 1.7-2.3%) after laparoscopic cholecystectomy. Five studies including 486,292 patients reported on intestinal obstruction that ranged from 0 to 6%. Meta-analysis estimated a long-term rate of intestinal obstruction of 1.3% (95% CI 0.8-1.8%).

CONCLUSION

Long-term mortality after laparoscopic cholecystectomy was 2%. The incidence of long-term intestinal obstruction after laparoscopic cholecystectomy was 1.3%.

Long-Term Outcomes of Elderly Patients Managed Without Early Cholecystectomy After Endoscopic Retrograde Cholangiopancreatography and Sphincterotomy for Choledocholithiasis

Background

Prophylactic cholecystectomy following endoscopic retrograde cholangiopancreatography with sphincterotomy (ERCP-S) remains the gold standard management of choledocholithiasis. Some clinicians propose ERCP-S alone as the definitive management in the elderly, given perioperative complication risks. This retrospective cohort study aimed to assess the long-term efficacy and safety of non-operative management of choledocholithiasis in adults aged ≥70.

Methodology

A total of 252 patients aged ≥70 underwent ERCP from 2004 to 2014 at a single institution. The rates of cholecystectomy, ERCP, complications, and mortality were gathered. Data were linked to a provincial health database to capture follow-up visits to alternate hospitals. Predictors of operation, recurrence, and mortality were analyzed using multivariable regression.

Results

Following ERCP, of the 252 patients, 33 (13.1%) underwent prophylactic cholecystectomy within three months, while 219 (86.9%) were initially managed conservatively. Of the 219 patients, 147 (67.1%) experienced no further choledocholithiasis after conservative management, while 23 (10.5%) patients underwent cholecystectomy. The mean follow-up was 2.9 years. Delayed operative patients were younger (mean age: 77.56 vs. 82.90; p < 0.001) and had lower Charlson Comorbidity Index (CCI) (1.04 vs. 1.84; p = 0.030). When adjusted for age, CCI score, and sex, cholecystectomy was associated with increased survival, with an odds ratio of 0.48 (95% confidence interval = 0.26-0.90; p = 0.021). Perioperative complications occurred in 7/56 (12.5%) patients.

Conclusions

Recurrent choledocholithiasis is common in elderly patients. Despite recurrent symptoms, these patients are unlikely to undergo cholecystectomy. Surgeons operate on patients with greater life expectancy and fewer comorbidities with high success despite advanced patient age. Future prospective studies should examine objective criteria for prophylactic cholecystectomy in this population, given purported safety and benefits.

Low long-term incidence of incisional hernia after cholecystectomy: A systematic review with meta-analysis

BACKGROUND

Various surgical approaches are available for cholecystectomy, but their long-term outcomes, such as incidence of incisional hernia, are largely unknown. Our aim was to investigate the long-term incidence of incisional hernia after cholecystectomy for different surgical approaches.

METHODS

This systematic review and meta-analysis was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A protocol was registered on PROSPERO (CRD42020178906). Three databases were searched for original studies on long-term complications of cholecystectomy with n > 40 and follow-up ≥6 months for incisional hernia. Risk of bias within the studies was assessed using the Newcastle-Ottawa Scale and the Cochrane "risk of bias" tool. Meta-analysis of the incidence of incisional hernia after 6 and 12 months was conducted when possible.

RESULTS

We included 89 studies. Of these, 77 reported on multiport or single-incision laparoscopic cholecystectomy. Twelve studies reported on open cholecystectomy and 4 studies on robotic cholecystectomy. Weighted mean incidence proportion of incisional hernia after multi-port laparoscopic cholecystectomy was 0.3% (95% confidence interval 0-0.6) after 6 months and 0.2% after 12 months (95% confidence interval 0.1-0.3). Weighted mean incidence of incisional hernia 12 months postoperatively was 1.5% (95% confidence interval 0.4-2.6) after open cholecystectomy and 4.5% (95% confidence interval 0.4-8.6) after single-incision laparoscopic cholecystectomy. No meta-analysis could be conducted for robotic cholecystectomy, but incidences ranged from 0% to 16.7%.

CONCLUSION

We found low 1-year incidences of incisional hernia after multiport laparoscopic and open cholecystectomy, whereas risks of incisional hernia were considerably higher after single-incision laparoscopic and robotic cholecystectomy.

Perioperative outcomes after laparoscopic cholecystectomy in elderly patients: a systematic review and meta-analysis

BACKGROUND

Laparoscopic cholecystectomy is increasingly performed in an ever ageing population; however, the risks are poorly quantified. The study aims to review the current evidence to quantify further the postoperative risk of cholecystectomy in the elderly population compared to younger patients.

METHOD

A systematic literature search of PubMed, EMBASE and the Cochrane Library databases were conducted including studies reporting laparoscopic cholecystectomy in the elderly population. A meta-analysis was reported in accordance with the recommendations of the Cochrane Library and PRISMA guidelines. Primary outcome was overall complications and secondary outcomes were conversion to open surgery, bile leaks, postoperative mortality and length of stay.

RESULTS

This review identified 99 studies incorporating 326,517 patients. Increasing age was significantly associated with increased rates of overall complications (OR 2.37, CI95% 2.00-2.78), major complication (OR 1.79, CI95% 1.45-2.20), risk of conversion to open cholecystectomy (OR 2.17, CI95% 1.84-2.55), risk of bile leaks (OR 1.50, CI95% 1.07-2.10), risk of postoperative mortality (OR 7.20, CI95% 4.41-11.73) and was significantly associated with increased length of stay (MD 2.21 days, CI95% 1.24-3.18).

CONCLUSION

Postoperative outcomes such as overall and major complications appear to be significantly higher in all age cut-offs in this meta-analysis. This study demonstrated there is a sevenfold increase in perioperative mortality which increases by tenfold in patients > 80 years old. This study appears to confirm preconceived suspicions of higher risks in elderly patients undergoing cholecystectomy and may aid treatment planning and informed consent.

Outcome of acute pancreatitis in octogenarians: A retrospective study

Background and Aim

Acute pancreatitis (AP) is a common disease, but data on outcomes in octogenarians are scarce in the literature. The aim of this study is to analyze results from patients aged 80 years old and over who were treated for AP at a single center.

Methods

Patients aged 80 years and older diagnosed with AP from April 2010 to October 2015 were considered. Demographics, American Society of Anesthesiologists (ASA) score, Charlson Comorbidity Index (CCI), serum biochemistry at 24 and 48 h after admission, and revised Atlanta severity score were analyzed and correlated with hospital mortality rate and length of stay using the multiple regression and Kaplan–Meier tests.

Results

A total of 100 consecutive patients were included in the study. There were 52 women, and the mean age was 87.5 years (range 80–95). Gallstones were the most common cause of AP (69.7%). The ASA score was ≥III in 51 patients. Eight patients had severe, disease and all of them died in hospital. A CCI > 4 was associated with higher disease severity and mortality (P < 0.00001). The median hospital stay was 9 days (range 1–59). Longer hospital stay was associated with serum C‐reactive protein ≥242 mg/L (P = 0.01) and serum albumin ≤30 g/L (P = 0.01) at 48 h. Over a 5‐year period, 22% of patients were readmitted to hospital with recurrent AP. Gallstones were the main cause of disease (63.6%).

Conclusions

AP in octogenarians has low mortality. Higher death rate is associated with disease severity. In the presence of gallstone disease, cholecystectomy is recommended whenever possible as the risk of disease recurrence is significant.

Outcomes and risk factors of cholecystectomy in high risk patients: A case series

Introduction

Many studies looked at outcomes and risk factors in laparoscopic cholecystectomies in general, including a few studies on risk factors and scoring systems in predicting conversion to open surgery. Little data has been produced on high-risk patients undergoing cholecystectomy. Identifying risk factors in this group could help stratify decision making regarding best management strategies.

The aim of this study was to investigate outcomes of laparoscopic cholecystectomies in patients with ASA 3 and 4.

Methods

Data was collected and collated from a prospectively maintained database of all laparoscopic cholecystectomies performed by 13 general surgeons in a single unit. Case notes were reviewed for all patients with ASA 3 and 4 between 2013 and 2017. Data analysis was performed using R studio v 3.4.

Results

244 cases were reviewed. Common bile duct was dilated in 52 cases (21.31%). Gall bladder wall was thick in 102 (41.8%) of the patients. Surgery was elective in 203 (83.2%) of the patients. ERCP was performed in 41 (16.9%) of the patients prior to surgery. 150 patients (62.2%) stayed for 1 day while 36 (14.9%) stayed for 2 days and the remaining 55 (22.9%) stayed for 3 days or more. Complications occurred in 37 (15.16%) of the patients while 23 (9.43%) of the patients were readmitted. 7 patients (2.87%) returned to theatre and 8 (3.28%) stayed in ITU post-op. Two patients died (0.82%).

Conclusion

Laparoscopic cholecystectomies in higher risk populations are safe. Alternative methods such as cholecystostomy and ERCP may be of benefit in these patients.

•

Gallstone disease represents a significant volume of elective and emergency work in the United Kingdom.

•

The primary aim of the study was to explore the factors that lead to complications in high risk patients (ASA 3-4).

•

Histological gallbladder thickness and emergency surgery were the factors most strongly associated with negative outcomes.

•

Age greater than 65 as an independent variable does not lead to an increase in negative outcomes.

•

Cholecystectomy is a relatively safe procedure in what is typically considered higher risk patients.

Early laparoscopic cholecystectomy is associated with less risk of complications after the removal of common bile duct stones by endoscopic retrograde cholangiopancreatography

BACKGROUND/AIMS

Several studies recommend prompt laparoscopic cholecystectomy (LC) following endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. However, histopathological alterations in the gallbladder during this time interval and the role played by ERCP in causing these changes have not been sufficiently elucidated. To compare early period LCs with delayed LCs following common bile duct stone extraction via ERCP with regard to operation time, hospitalization period, conversion to open cholecystectomy rate, morbidity, mortality, and histopathological alterations in the gallbladder wall.

MATERIALS AND METHODS

A total of 85 patients were retrospectively divided into three groups: early period LC group (48-72 h; n=30), moderate period LC group (72 h-6 weeks; n=25), and delayed period LC group (6-8 weeks; n=30).

RESULTS

The operation time was significantly shorter, and the total number of complication rates and hospital readmission was significantly less frequent in the early period LC group (p<0.05). Ultrasound showed a significantly thicker gallbladder wall (>3 mm) in the moderate and late period LC groups than in the early period LC group (p<0.001). Culture growth was significantly higher, and fibrosis/collagen deposition in the gallbladder wall with injury to the mucosal epithelium was significantly more frequently detected by histopathological examination in the moderate and late period LC groups than in the early period LC group (p<0.05).

CONCLUSION

Early period LC following stone extraction by ERCP is associated with shorter operation time, fewer fibrotic changes in the gallbladder, and lower risk for the development of complications. Therefore, LC can be performed safely in the early period after ERCP.

Safety and outcomes of laparoscopic cholecystectomy in the extremely elderly: a systematic review and meta-analysis

Background: Gallstones are a common cause of morbidity in the elderly. Operative treatment is often avoided due to concerns about poor outcomes but the evidence for this is unclear. We aim to consolidate available evidence assessing laparoscopic cholecystectomy outcomes in the extreme elderly (>80s) compared to younger patients. Methods: Studies comparing laparoscopic cholecystectomy in >80s with younger patients were considered. Total complications, mortality, conversion, bile duct injury, and length of stay were compared between the two groups. Results: Twelve studies including 366,522 patients were included. They were of moderate overall quality. The elderly group had more complicated gallbladder disease and also had more co-morbidities and a higher ASA grade. The risk of morbidity was lower in the younger group (RR 0.58 (95% CI 0.58-0.59)) with a slightly lower risk of conversion (RR 0.96 (0.94-0.98)) Length of stay was significantly longer for the elderly patients. Differences in mortality and bile duct injury were non-significant in all but one study. Conclusion: Laparoscopic cholecystectomy is safe and effective in the extreme elderly. Higher complication rates are predominantly related to increased co-morbidities and more complex gallbladder disease. Patients should be carefully selected, and cholecystectomy performed at an earlier stage to minimize these problems.

Cholecystectomy after Endoscopic Papillotomy for Choledocholithiasis in the Elderly—Is It Necessary?

Although elective laparoscopic cholecystectomy is the accepted strategy after endoscopic retrograde cholangiopancreatography (ERCP), papillotomy, and common bile duct (CBD) clearance, the decision to perform a cholecystectomy in high-risk elderly comorbid patients remains subjective and is controversial. The aim of this study was to examine the outcome of elderly patients with cholecystectomy deferral after successful initial endoscopic removal of CBD stones. The study examined a retrospective patient database, which included all patients aged >60 years who underwent an ERCP for CBD stones at the Chaim Sheba Medical Center. The study cohort was divided according to whether a subsequent cholecystectomy was performed and also by age 60 to 80 or >80 years. All biliary-related complications were recorded. The primary outcome measures were biliary complications, perioperative and periprocedural mortality, CBD stone recurrence, and the need for future surgical intervention. There were 111 patients (mean age 79.4 ± 9.1 years) who underwent ERCP with follow-up. After excluding 11 patients, 100 patients were left for analysis, 46 of whom underwent a cholecystectomy and 54 were observed without operation. There were significant longer term biliary complications in five of the operated patients (10.9%) and in four of the unoperated cases (7.4%). All biliary-related complications were managed successfully by conservative means except for one fatality in the nonoperated group. Biliary-related complications after successful ERCP for CBD stones were unaffected by surgery but were more commonly observed in older cases. A watch and wait policy may be justified in elderly comorbid patients.

One-stage laparoscopic procedure versus two-stage procedure in the management of common bile duct stones in patients aged 75 and more

INTRODUCTION

The management strategy for common bile duct stones (CBD) in patients over 75years is a real challenge that requires balancing the efficacy of a multiplicity of procedures against their own morbidity. The objective is to compare one-stage surgical treatment versus the two-stage combination of endoscopy and surgery in terms of efficacy of clearing the CBD of stones and the morbidity and mortality in elderly patients.

MATERIAL AND METHODS

This study included eighty-two patients over 75years of age with symptomatic CBD stones who presented between 2010 and 2017. Patients were treated either by one-stage surgery alone (S group, n=40) or by sequential endoscopy and surgery (ES group, n=42).

RESULTS

Immediate and 30-day mortality, morbidity and duration of hospitalization were comparable. The failure rate for clearing CBD lithiasis was significantly higher in the ES group (26.2% vs. 7.5%, P=0.038, 95% CI). In multivariate analysis, two-stage treatment and multiple CBD stones were associated with a significantly higher risk of failure. Fewer anesthetic procedures were needed in the S group. Twelve patients (14.4%) had multiple stones packing the CBD (>3 stones); four were treated with choledocho-duodenal anastomosis and eight with endoscopic sphincterotomy and stone removal with 100% and 50% efficacy, respectively.

CONCLUSION

The "surgery alone" attitude compared to 2-stage endoscopic and surgical management is associated with better efficacy in terms of clearing the CBD of lithiasis and requires fewer anesthetic procedures in elderly subjects while being comparable in terms of morbidity and mortality. In patients whose CBD is packed with multiple stones, choledocho-duodenal anastomosis is an alternative to endoscopy for management of choledocholithiasis.

Laparoscopic common bile duct exploration; a preferential pathway for elderly patients

Background

Laparoscopic common bile duct exploration (LCBDE) has emerged as a recommended alternative to endoscopic retrograde cholangiopancreatography (ERCP) for the management of choledocholithiasis. However, its use in the elderly has been limited, and evidence of its safety and efficacy in these patients is yet to be established. This study describes our experience of LCBDE in elderly patients, analysing the safety and efficacy of this technique in comparison to younger patients.

Methods

All patients undergoing laparoscopic cholecystectomy (LC) with LCBDE for choledocholithiasis in our unit between January 2015 and January 2017 were included. Data pertaining to patient demographics, comorbidities, investigations, operative technique and outcomes were analysed. Patients were divided into 2 groups based on age (Group A:<65 years vs Group B: >/ = 65 years) for comparative analysis.

Results

124 patients (Group A: 65, Group B: 59) were included. Group B were more co-morbid and had a higher ASA grade than Group A. However, there was no significant difference between groups in rates of conversion to open or complications, including bile leak (3.1% vs 5.1%, p = 0.67), retained stone (4.6% vs 1.7%, p = 0.62), or complications according to Clavien-Dindo classification (p = 0.78). Re-intervention rates were also similar between groups (7.7% vs 3.4%, p = 0.44 and 3.1% vs 3.4%, p = 1.0 respectively), as was length of stay.

Conclusion

Despite higher frequency of comorbidities and ASA grade, LCBDE in elderly patients is safe and effective, and has similar outcomes to younger patients. Therefore elderly patients with choledocholithiasis should be offered LCBDE as an alternative to ERCP.

Single-stage laparoscopic common bile duct exploration and cholecystectomy versus two-stage endoscopic stone extraction followed by laparoscopic cholecystectomy for patients with gallbladder stones with common bile duct stones: systematic review and meta-analysis of randomized trials with trial sequential analysis

BACKGROUND

The ideal management of common bile duct (CBD) stones associated with gall stones is a matter of debate. We planned a meta-analysis of randomized trials comparing single-stage laparoscopic CBD exploration and cholecystectomy (LCBDE) with two-stage preoperative endoscopic stone extraction followed by cholecystectomy (ERCP + LC).

METHODS

We searched the Pubmed/Medline, Web of science, Science citation index, Google scholar and Cochrane Central Register of Controlled trials electronic databases till June 2017 for all English language randomized trials comparing the two approaches. Statistical analysis was performed using Review Manager (RevMan) [Computer program], Version 5.3. Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration, 2014 and results were expressed as odds ratio for dichotomous variables and mean difference for continuous. p value ≤ 0.05 was considered significant. Trial sequential analysis (TSA) was performed using TSA version 0.9.5.5 (Copenhagen: The Copenhagen Trial Unit, Centre for Clinical Intervention Research, 2016). PROSPERO trial registration number is CRD42017074673.

RESULTS

A total of 11 trials were included in the analysis, with a total of 1513 patients (751-LCBDE; 762-ERCP + LC). LCBDE was found to have significantly lower rates of technical failure [OR 0.59, 95% CI (0.38, 0.93), p = 0.02] and shorter hospital stay [MD - 1.63, 95% CI (- 3.23, - 0.03), p = 0.05]. There was no significant difference in mortality [OR 0.37, 95% CI (0.09, 1.51), p = 0.17], morbidity [OR 0.97, 95% CI (0.70, 1.33), p = 0.84], cost [MD - 379.13, 95% CI (- 784.80, 111.2), p = 0.13] or recurrent/retained stones [OR 1.01, 95% CI (0.38, 2.73), p = 0.98]. TSA showed that although the Z-curve crossed the boundaries of conventional significance, the estimated information size is yet to be achieved.

CONCLUSIONS

Single-stage LCBDE is superior to ERCP + LC in terms of technical success and shorter hospital stay in good-risk patients with gallstones and CBD stones, where expertise, operative time and instruments are available.

Surgery in biliary lithiasis: from the traditional "open" approach to laparoscopy and the "rendezvous" technique

BACKGROUND

According to the current literature, biliary lithiasis is a worldwide-diffused condition that affects almost 20% of the general population. The rate of common bile duct stones (CBDS) in patients with symptomatic cholelithiasis is estimated to be 10% to 33%, depending on patient's age. Compared to stones in the gallbladder, the natural history of secondary CBDS is still not completely understood. It is not clear whether an asymptomatic choledocholithiasis requires treatment or not. For many years, open cholecystectomy with choledochotomy and/or surgical sphincterotomy and cleaning of the bile duct were the gold standard to treat both pathologies. Development of both endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic surgery, together with improvements in diagnostic procedures, influenced new approaches to the management of CBDS in association with gallstones.

DATA SOURCES

We decided to systematically review the literature in order to identify all the current therapeutic options for CBDS. A systematic literature search was performed independently by two authors using PubMed, EMBASE, Scopus and the Cochrane Library Central.

RESULTS

The therapeutic approach nowadays varies greatly according to the availability of experience and expertise in each center, and includes open or laparoscopic common bile duct exploration, various combinations of laparoscopic cholecystectomy and ERCP and combined laparoendoscopic rendezvous.

CONCLUSIONS

Although ERCP followed by laparoscopic cholecystectomy is currently preferred in the majority of hospitals worldwide, the optimal treatment for concomitant gallstones and CBDS is still under debate, and greatly varies among different centers.

Laparoscopic common bile duct exploration: a safe and definitive treatment for elderly patients

BACKGROUND

Common bile duct (CBD) stone is one of the most common diseases among elderly people. In recent decades, there are numerous studies regarding the safety and efficacy of laparoscopic common bile duct exploration (LCBDE). Elderly patients are often regarded as high-risk patients because they are more likely to present with age-specific deterioration of organ function and coexisting chronic diseases, which may reduce their tolerance of laparoscopic surgery. Although laparoscopic surgery for choledocholithiasis is now widely accepted as the treatment for CBD stone, its appropriateness for the treatment of elderly patients or those with coexisting high-risk patients has not been well established. Therefore, the objective of this paper is to analyze the safety and efficacy of LCBDE in elderly patients.

METHODS

Between January 2012 and November 2015, 376 patients underwent LCBDE in our center. Based on their ages, they were divided into two groups, and a retrospective study was performed. By making comparisons between younger group who were younger than 70 years (n = 253) and elderly group who were 70 years old or older (n = 123), the demographics, clinical characteristics, laboratory data, operative parameters and outcomes were analyzed.

RESULTS

Before operation, elderly patients had more coexisting chronic diseases and risk factors, such as arterial hypertension, heart diseases, pulmonary diseases and previous abdominal surgery (P < 0.05). In both groups, LCBDE was equally successful with a high clearance rate (100 % in elderly patients vs. 98.8 % in younger group, P = 0.554). Besides, the operating time, intraoperative blood loss, postoperative hospital stay, total costs and overall complication showed no significant difference between two groups (P > 0.05). There was no major bile duct injury or death in either group.

CONCLUSION

Although elderly patients are frequently confronted with coexisting disorders, LCBDE can be considered as a safe and effective technique in choledocholithiasis treatment for elderly patients.

High rate of common bile duct stones and postoperative abscess following percutaneous cholecystostomy

INTRODUCTION

The short and long-term outcomes in patients managed with percutaneous cholecystostomy (PCY) at a single institution are described.

METHODS

A retrospective study was conducted for patients treated between February 2000 and November 2012. Patient charts, imaging and biochemical data were reviewed. Patient demographics, presenting clinical features and treatment variables were noted. Outcome variables were length of admission, 30-day mortality, 30-day unplanned readmission, tube dislodgement, abscess formation, subsequent endoscopic retrograde cholangiography and surgery, complications after surgery and median overall survival.

RESULTS

PCY was performed for 55 patients for acute cholecystitis where surgical risk was very high. The 30-day readmission rate was 20% (n=11), the 30-day mortality rate was 9% (n=5) and median survival was 59 months (95% confidence interval: 30-88 months). The median follow-up duration was 68 months. Tubes were dislodged in 15 patients (27%) and an abscess occurred after PCY in 5 patients (9%). Subsequent endoscopic common bile duct stone extraction was required in 20 patients (36%). Cholecystectomy was planned in 22 patients and an abscess occurred following the cholecystectomy in 5 (23%).

CONCLUSIONS

Although a PCY is lifesaving, significant morbidity can arise during recovery. This study demonstrates a high rate of choledocholithiasis (44%), tube dislodgement (27%) and postoperative abscess (23%) compared with previous reports.

Diagnosis and management of choledocholithiasis in the golden age of imaging, endoscopy and laparoscopy

Biliary lithiasis is an endemic condition in both Western and Eastern countries, in some studies affecting 20% of the general population. In up to 20% of cases, gallbladder stones are associated with common bile duct stones (CBDS), which are asymptomatic in up to one half of cases. Despite the wide variety of examinations and techniques available nowadays, two main open issues remain without a clear answer: how to cost-effectively diagnose CBDS and, when they are finally found, how to deal with them. CBDS diagnosis and management has radically changed over the last 30 years, following the dramatic diffusion of imaging, including endoscopic ultrasound (EUS) and magnetic resonance cholangiography (MRC), endoscopy and laparoscopy. Since accuracy, invasiveness, potential therapeutic use and cost-effectiveness of imaging techniques used to identify CBDS increase together in a parallel way, the concept of “risk of carrying CBDS” has become pivotal to identifying the most appropriate management of a specific patient in order to avoid the risk of “under-studying” by poor diagnostic work up or “over-studying” by excessively invasive examinations. The risk of carrying CBDS is deduced by symptoms, liver/pancreas serology and ultrasound. “Low risk” patients do not require further examination before laparoscopic cholecystectomy. Two main “philosophical approaches” face each other for patients with an “intermediate to high risk” of carrying CBDS: on one hand, the “laparoscopy-first” approach, which mainly relies on intraoperative cholangiography for diagnosis and laparoscopic common bile duct exploration for treatment, and, on the other hand, the “endoscopy-first” attitude, variously referring to MRC, EUS and/or endoscopic retrograde cholangiography for diagnosis and endoscopic sphincterotomy for management. Concerning CBDS diagnosis, intraoperative cholangiography, EUS and MRC are reported to have similar results. Regarding management, the recent literature seems to show better short and long term outcome of surgery in terms of retained stones and need for further procedures. Nevertheless, open surgery is invasive, whereas the laparoscopic common bile duct clearance is time consuming, technically demanding and involves dedicated instruments. Thus, although no consensus has been achieved and CBDS management seems more conditioned by the availability of instrumentation, personnel and skills than cost-effectiveness, endoscopic treatment is largely preferred worldwide.

[Biliary diseases in the elderly]

Gallstone disease is more common in the elderly. In this short review, we summarize guideline-based recommendations for the diagnosis and treatment of biliary diseases in elderly patients. Warning episodes of biliary colic represent a general indication for cholecystectomy to avoid stone-related complications. Elderly patients with mild and moderate acute cholecystitis should undergo urgent cholecystectomy. After endoscopic retrograde cholangiography and stone extraction as well as mild acute biliary pancreatitis, cholecystectomy should be performed during the same hospital admission. Since the elevated risk of gallstone carriers to develop biliary cancer increases with age, cholecystectomy also protects against cancer.

Rendezvous technique for cholecystocholedochal lithiasis in octogenarians: is it as effective as in younger patients, or should endoscopic sphincterotomy followed by laparoscopic cholecystectomy be preferred?

BACKGROUND

The treatment of cholecystocholedochal lithiasis (CCL) requires cholecystectomy and common bile duct (CBD) clearance, which can be achieved surgically or with a combination of surgery and endoscopy. The latter includes a two-stage-approach-preoperative retrograde cholangiography (ERC) and sphincterotomy (ST) followed by delayed laparoscopic cholecystectomy (LC), or vice versa-or a one-stage-approach-the rendezvous technique (RVT), where ERC, ST, and LC are performed during the same procedure. No data on the use of RVT in octogenarians have been reported in the literature so far. The study aims to show whether the RVT is as effective in elderly as in younger patients. Moreover, results of RVT are compared with those of a two-stage sequential treatment (TSST) in octogenarians, to identify the best approach to such a population.

SUBJECTS AND METHODS

Prospectively collected data of 131 consecutive patients undergoing RVT for biliary tract stone disease were retrospectively analyzed. Two analyses were performed: (1) results of RVT (operative time, conversion rate, CBD clearance, morbidity/mortality, hospital stay, costs, and need for further endoscopy) were compared between octogenarians and younger patients, and (2) results of RVT in the elderly were compared with those of 27 octogenarians undergoing TSST for CCL.

RESULTS

Octogenarians undergoing RVT were in poorer general condition (P<.0001) and had a higher conversion rate (P<.0001) and a longer hospital stay (P<.007) than younger patients. No differences in the rates of CBD clearance, surgery-related morbidity, mortality, and costs were recorded. Although octogenarians undergoing RVT were in poorer general condition than those undergoing TSST, the results of the two approaches were similar.

CONCLUSIONS

RVT in the elderly seems to be as cost-effective as in younger patients; nevertheless, it may lead to a higher conversion rate and longer hospital stay. In octogenarians, RVT is not inferior to TSST in the treatment of CCL even for patients in poor condition.

Recurrent cholangitis after endoscopic lithotripsy of common bile duct stones with gallstones in situ: predictive factors with and without subsequent cholecystectomy

BACKGROUND

Common bile duct stones are a frequent complication of gallstones. Endoscopic retrograde cholangiopancreatography and sphincterotomy are often performed to evaluate the etiology of obstructive jaundice and for concomitant therapeutic removal of common bile duct stones. We aimed to evaluate the recurrence rate of cholangitis or cholecystitis after endoscopic lithotripsy with gallstones in situ and to identify associated predictive factors.

PATIENTS AND METHODS

We retrospectively reviewed 183 patients who had received endoscopic lithotripsy between July 2007 and June 2010. We divided patients into two groups: One group who had received subsequent cholecystectomy (n=66) and one observational group (n=117). Patients with previous cholecystectomy or without gallstones were excluded. All included patients were followed up at our outpatient department. Our end point was the presence of symptoms of recurrent cholangitis or cholecystitis.

RESULTS

Subjects included 86 males and 97 females with a mean age of 62.5±16.3 years (range, 43-81 years). Cholangitis or cholecystitis recurred in 6 patients in the cholecystectomy group and 30 patients in the observational group. Findings revealed a lower recurrence rate and longer recurrence-free period in patients who received subsequent cholecystectomy. The recurrence rate of the observational group was significantly higher than that of the cholecystectomy group (25.6% versus 9.1%, P=.007). Univariate and multivariate Cox regression analyses revealed that common bile duct dilatation was an independent predictive factor for recurrence.

CONCLUSIONS

Cholecystectomy is recommended after endoscopic lithotripsy. Common bile duct dilatation is associated with the rate of recurrent cholangitis or cholecystitis.

The timing of laparoscopic cholecystectomy after endoscopic retrograde cholangiopancreaticography in cholelithiasis coexisting with choledocholithiasis

BACKGROUND

An accepted treatment strategy for cholelithiasis with secondary choledocholithiasis is the laparoscopic cholecystectomy (LC) following endoscopic retrograde cholangiopancreaticography (ERCP). Although early cholecystectomy is advised, there is no consensus about the time interval between LC and ERCP. The aim of this study is to evaluate the effects of the time interval between ERCP and ERCP on operation outcomes.

METHODS

Patients with cholelithiasis and a risk of choledocholithiasis underwent ERCP. Patients were grouped as those operated on between 24 and 72 h after ERCP (group 1) and those operated on more than 72 h after ERCP (group 2). Patients' age, gender, body mass index, American Society of Anesthesiologists Physical Status, abdominal ultrasonography findings, white blood cell count, total serum bilirubin, ALP, amylase, ALT, AST, GGT levels, ERCP findings, time interval between ERCP and LC, conversion rate, median postoperative hospital stay, median operation time, intraoperative complication and postoperative complication rates were collected.

RESULTS

There was no significant difference between the demographics of the patients in both groups. The median operation time, median postoperative hospital stay and conversion rate in group 2 were significantly higher than those of group 1. More postoperative complications were seen in group 2.

CONCLUSION

Early cholecystectomy after ERCP, within 72 h, has better outcomes, probably due to the inflammatory processes.

[Laparoscopic cholecystectomy in patients aged 80 and over]

INTRODUCTION

The increasing aging of the population also increases the prevalence of symptomatic gallbladder diseases. It is important to analyse their surgical treatment in the elderly.

METHODS

All the laparoscopic cholecystectomies performed in our surgery department on patients aged 80 years-old or over from 1992 to 2007 were included in this study.

RESULTS

Laparoscopic cholecystectomy was performed on 133 patients 80 years-old and over, with 63% of them women, and an average age of 83.23 years. Biliary colic (29%) and acute pancreatitis (44%) were the main reasons for surgery. Associated diseases were found in 73% of them. Only 7.5% needed urgent surgery, even although 71% were admitted urgently. There were 13.5% conversions to open surgery, 17% morbidity and 2.3% mortality.

CONCLUSIONS

Laparoscopic cholecystectomy can be recommended in symptomatic gallbladder disease in the elderly.

Laparo-endoscopic “Rendezvous” to treat cholecysto-choledocolithiasis: Effective, safe and simplifies the endoscopist’s work

AIM: To investigate our clinical experience with combined laparo-endoscopic Rendezvous (RV) for the treatment of patients affected by gallstones and common bile duct (CBD) stones and especially to study the never evaluated opinion of the endoscopist concerning the difficulty of the intraoperative endoscopic procedure during the RV in comparison with standard endoscopic retrograde cholangio-pancreatography (ERCP).

METHODS: Eighty consecutive patients affected by cholecystolithiasis and diagnosed or suspected CBD stones were treated with a standardized “tailored” RV. The relevant technical features, the feasibility, the effectiveness in stone clearance, the safety but also the simple evaluation of difficulty and agreement of the endoscopist were analyzed with a questionnaire.

RESULTS: The feasibility was 97.5% and the effectiveness 100% concerning CBD clearance and solution of coexisting problems at the papilla. Minor morbidity was 3.3%, the operating time was prolonged by a mean of 14 min, the mean hospital stay was 3.8 d and only one stone’s recurrence occurred. The endoscopist evaluated the procedure to be simpler than standard ERCP-ES in 81.2% of the cases.

CONCLUSION: Simultaneous RV carries high effectiveness and safety at least comparable to those reported for other options. The endoscopist is very often satisfied with this approach because of the minimization of some steps of the endoscopic procedure and avoidance of relevant iatrogenic risk factors. If the mandatory collaboration between surgeons and endoscopists is guaranteed, this approach can often be preferable for the patient, the surgeon, the endoscopist and the hospital.

Considerations concerning laparoscopic cholecystectomy in the extremely elderly

BACKGROUND

Since octogenarians become a growing part of the population and surgical care is possible in them, this study was conducted to evaluate the outcome of laparoscopic cholecystectomy in patients 80 years of age and over.

METHODS

From June 1993 to May 2006, a total of 1263 patients underwent a laparoscopic cholecystectomy, applying the four-trocar American technique; 21 among them were >/=80 years. We retrospectively reviewed patients' age, gender, indication for surgery, comorbid conditions, American Society of Anesthesiologists (ASA) score, conversion to open procedure, postoperative complications, and length of hospital stay.

RESULTS

The mean age in the >/=80 group was 82.5+/-3 and 57% were women, while in the <80 group 72% of patients were women. Recurrent biliary colic was the most frequent (62%) indication for surgery among the elderly patients. Endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy were performed preoperatively in 6 elderly patients (29%); there were 4 cases of acute calculus pancreatitis and 2 cases of acute cholangitis. A high surgical risk (ASA score of III and IV) was estimated in 11 patients (52%) from the >/=80 group versus 32% in the <80 group (P =0.047). Conversion rate was higher (19%) and hospital stay was longer (4.9 days) in the >/=80 group, compared to younger patients (P =0.01). Mortality was zero and morbidity was 14% versus 3% in the <80 group (P =0.03), including 1 case of postoperative bleeding, 1 case of wound infection, and 1 case of pulmonary atelectasis, respectively.

CONCLUSIONS

Laparoscopic cholecystectomy in the extremely elderly is safe and well tolerated; however, it is associated with a higher conversion rate, increased morbidity, and a longer hospital stay.
