Laparoscopic cholecystectomy for acute cholecystitis: early or delayed?: Evidence from a systematic review of discordant meta-analyses

Intravenous injection versus transhepatic intracholecystic injection of indocyanine green (ICG) to outline biliary tree during laparoscopic cholecystectomy

BACKGROUND

To potentially lessen injuries and associated complications, fluorescence cholangiography has been suggested as a technique for enhancing the visualization and identification of extrahepatic biliary anatomy. The most popular way to administer indocyanine green (ICG) is intravenously, as there is currently little data on ICG injections directly into the gallbladder. In order to visualize extrahepatic biliary anatomy during laparoscopic cholecystectomy (LC), we compared the two different ICG administration techniques. We also examined variations in visualization time, as well as the effectiveness, benefits, and drawbacks of each modality.

METHODS

In this prospective randomized clinical study, 60 consecutive adult patients with chronic and acute gallbladder disease were included. Our study conducted from 2022 to 2024 in Surgical Department of Theodor Bilharz Research Institute. Thirty patients underwent LC with intravenous ICG administration (IV-ICG), thirty patients received a direct injection of gallbladder through transhepatic ICG (IC-ICG) and Preoperative, intraoperative, and postoperative patient data were examined.

RESULTS

In terms of their perioperative and demographic features, the groups were similar. Without a statistically significant difference, the IV-ICG group's total operating time was less than that of the IC-ICG group (p 0.140). Compared to the transhepatic IC-ICG method, IV-ICG was more accurate in identifying the duodenum and the common hepatic duct (p = 0.029 and p = 0.016, respectively). In the transhepatic IC-ICG and IV-ICG groups, the cystic duct could be identified prior to dissection in 66.6% and 73.3% of cases, respectively, and this increased to 86.6% and 93.3% following dissection. In the transhepatic IC-ICG group, the common bile duct was visible in 93.3% of cases; in the IV-ICG group, it was visible in 90% of cases. Two cases in the IC-ICG group and every case following IV-ICG administration had liver fluorescence (6.6% versus 100%; p < 0.001).

CONCLUSION

The current study shows that for both administration methods, ICG-fluorescence cholangiography can be useful in identifying the extrahepatic biliary anatomy during Calot's triangle dissection. By avoiding hepatic fluorescence, the transhepatic IC-ICG route can increase the bile duct-to-liver contrast with less expense and no risk of hypersensitivity reactions than the intravenous ICG injection method. We recommend to use both techniques in case of acute cholecystitis with cystic duct obstruction. In cases of liver cirrhosis, we recommend transhepatic IC-ICG as IV-ICG is limited.

Evaluation of the impact of prospective payment systems on cholecystectomy: A systematic review and meta-analysis

This systematic review and meta-analysis aimed to evaluate the impact of prospective payment systems (PPSs) on cholecystectomy. A comprehensive literature review was conducted, examining studies published until December 2023. The review process focused on identifying research across major databases that reported critical outcomes such as length of stay (LOS), mortality, complications, admissions, readmissions, and costs following PPS for cholecystectomy. The studies were specifically selected for their relevance to the impact of PPS or the transition from fee-for-service (FFS) to PPS. The study analyzed six papers, with three eligible for meta-analysis, to assess the impact of the shift from FFS to PPS in laparoscopic and open cholecystectomy procedures. Our findings indicated no significant changes in LOS and mortality rates following the transition from FFS to PPS. Complication rates varied and were influenced by the diagnosis-related group categorization and surgeon cost profiles under episode-based payment. There was a slight increase in admissions and readmissions, and mixed effects on hospital costs and financial margins, suggesting varied responses to PPS for cholecystectomy procedures. The impact of PPS on cholecystectomy is nuanced and varies across different aspects of healthcare delivery. Our findings indicate a need for adaptable, patient-centered PPS models that balance economic efficiency with high-quality patient care. The study emphasizes the importance of considering specific surgical procedures and patient demographics in healthcare payment reforms.

Improving early cholecystectomy rate in acute cholecystitis with an evidence-based local multidisciplinary protocol and a surgical audit: single-center experience through an Acute Care Surgery Division

PURPOSE

To analyze if, after implementation of an evidence-based local multidisciplinary protocol for acute cholecystitis (AC), an intermediate surgical audit could improve early cholecystectomy (EC) rate and other therapeutic indicators.

METHODS

Longitudinal cohort study at a tertiary center. The local protocol, promoted, created, and periodically revised by the Acute Care Surgery Unit (ACSu) was updated and approved on March 2019. A specific registry was prospectively fulfilled with demographics, comorbidity, type of presentation, diagnostic items, therapeutic decision, and clinical course, considering both non-operative management (NOM) or cholecystectomy, early and delayed (EC and DC). Phase 1: April 2019-April 2021. A critical analysis and a surgical audit with the participation of all the involved Departments were then performed, especially focusing on improving global EC rate, considered primary outcome. Phase 2: May 2021-May 2023. Software SPSS 23.0 was used to compare data between phases.

RESULTS

Initial EC rate was significantly higher on Phase 2 (39.3%vs52.5%, p < 0.004), as a significantly inferior rate of patients were initially bailed out from EC to NOM because of comorbidity (14.4%vs8%, p < 0.02) and grade II with severe inflammatory signs (7%vs3%, p < 0.04). A higher percentage of patients was recovered for EC after an initial decision of NOM on Phase 2, but without reaching statistical significance (21.8%vs29.2%, n.s.). Global EC rate significantly increased between phases (52.5%vs66.3%, p < 0.002) without increasing morbidity and mortality. A significant minor percentage of elective cholecystectomies after AC episodes had to be performed on Phase 2 (14%vs6.7%, p < 0.009). Complex EC and those indicated after readmission or NOM failure were usually performed by the ACSu staff.

CONCLUSION

To adequately follow up the implementation of a local protocol for AC healthcare, registering and periodically analyzing data allow to perform intermediate surgical audits, useful to improve therapeutic indicators, especially EC rate. AC constitutes an ideal model to work with an ACSu.

Effect of intramedullary fixation and plate fixation on postoperative wound complications in clavicle fractures: A meta-analysis

More and more meta-analyses have been conducted to compare the effects of intramedullary fixation (IF) and plate fixation (PF) on the outcome of midshaft clavicle fractures. It can affect the doctors' treatment decisions. A number of studies have been conducted in order to assist surgeons in selecting optimal operative procedures and to recommend operative treatment of clavicle fractures in accordance with the best available research. Our analysis of the IF and PF of clavicle fractures was done through a search for PubMed, Emabase, Web of Science, and Cochrane Library. Two different researchers analysed the research literature for quality of analysis and data extraction. The analysis of the data was done with RevMan 5.3. The 95% CI and OR models have been computed by means of either fixed-dose or randomize. In addition, RCT in 114 references have been reviewed and added for further analysis. It is concluded that the application of plate and intramedullary fixation in the middle clavicle operation has remarkable influence on the outcome of post-operation. There was a lower risk of postoperative wound infection in IF (OR, 5.92; 95% CI, 2.46, 14.27 p < 0.0001), smaller surgical incisions (MD, 6.57; 95% CI, 4.90, 8.25 p < 0.0001), and shorter operative time (MD, 17.09; 95% CI 10.42, 23.77 p < 0.0001), less blood loss (MD, 63.62; 95% CI, 55.84, 71.39 p < 0.0001) and shorter hospital stay (MD, 1.05; 95% CI, 0.84, 1.25 p < 0.0001). However, there is no statistical significance in the incidence of wound dehiscence. Thus, the effect of IF on the incidence of injury is better than that of the inner plate in the middle of the clavicle.

Cesena guidelines: WSES consensus statement on laparoscopic-first approach to general surgery emergencies and abdominal trauma

BACKGROUND

Laparoscopy is widely adopted across nearly all surgical subspecialties in the elective setting. Initially finding indication in minor abdominal emergencies, it has gradually become the standard approach in the majority of elective general surgery procedures. Despite many technological advances and increasing acceptance, the laparoscopic approach remains underutilized in emergency general surgery and in abdominal trauma. Emergency laparotomy continues to carry a high morbidity and mortality. In recent years, there has been a growing interest from emergency and trauma surgeons in adopting minimally invasive surgery approaches in the acute surgical setting. The present position paper, supported by the World Society of Emergency Surgery (WSES), aims to provide a review of the literature to reach a consensus on the indications and benefits of a laparoscopic-first approach in patients requiring emergency abdominal surgery for general surgery emergencies or abdominal trauma.

METHODS

This position paper was developed according to the WSES methodology. A steering committee performed the literature review and drafted the position paper. An international panel of 54 experts then critically revised the manuscript and discussed it in detail, to develop a consensus on a position statement.

RESULTS

A total of 323 studies (systematic review and meta-analysis, randomized clinical trial, retrospective comparative cohort studies, case series) have been selected from an initial pool of 7409 studies. Evidence demonstrates several benefits of the laparoscopic approach in stable patients undergoing emergency abdominal surgery for general surgical emergencies or abdominal trauma. The selection of a stable patient seems to be of paramount importance for a safe adoption of a laparoscopic approach. In hemodynamically stable patients, the laparoscopic approach was found to be safe, feasible and effective as a therapeutic tool or helpful to identify further management steps and needs, resulting in improved outcomes, regardless of conversion. Appropriate patient selection, surgeon experience and rigorous minimally invasive surgical training, remain crucial factors to increase the adoption of laparoscopy in emergency general surgery and abdominal trauma.

CONCLUSIONS

The WSES expert panel suggests laparoscopy as the first approach for stable patients undergoing emergency abdominal surgery for general surgery emergencies and abdominal trauma.

Timing of Elective Cholecystectomy After Acute Cholecystitis: A Population-based Register Study

BACKGROUND

Acute cholecystectomy is standard treatment for acute cholecystitis. However, many patients are still treated conservatively and undergo delayed elective surgery. The aim of this study was to determine the ideal time to perform an elective cholecystectomy after acute cholecystitis.

METHODS

All patients treated for acute cholecystitis in Sweden between 2006 and 2013 were identified through the Swedish Patient Register. This cohort was cross-linked with the Swedish Register for Gallstone Surgery, GallRiks, where information on surgical outcome was retrieved. The impact of the time interval after discharge from hospital to elective surgery was analysed by multivariate logistic regression adjusting for gender and age.

RESULTS

After exclusion of patients not subjected to surgery, not registered in GallRiks and patients treated with acute cholecystectomy, 8532 remained. This cohort was divided into six-time categories. Using the first time interval < 11 days from discharge to elective surgery as the reference category the chance of completing surgery with a minimally invasive technique was increased for all categories (p < 0.05). The risk for perioperative complication and cystic duct leakage was reduced if surgery was undertaken > 30 days after discharge (both p < 0.05). The risk for bile duct injury was significantly increased if the procedure was undertaken > 365 days after discharge (p = 0.030). The chance of completing the procedure within 100 min was not affected by time.

CONCLUSION

For patients undergoing elective cholecystectomy after acute cholecystitis, the safety of the procedure increases if surgery is performed more than 30 days after discharge from the primary admission.

Specialist-led urgent cholecystectomy for acute gallstone disease

BACKGROUND

Despite overwhelming evidence of the clinical and financial benefit of urgent cholecystectomy, there is variable enthusiasm and uptake across the UK. In 2014, following the First National Emergency Laparotomy Audit Organisational Report, we implemented a specialist-led urgent surgery service, whereby all patients with gallstone-related pathologies were admitted under the direct care of specialist upper gastrointestinal surgeons. We have analysed 5 years of data to investigate the results of this service model.

METHODS

Computerised operating theatre records were interrogated to identify all patients within a 5-year period undergoing cholecystectomy. Patient demographics, admission details, length of stay, duration of surgery, and complications were analysed.

RESULTS

Between 01/01/2016 and 31/12/2020, a total of 4870 cholecystectomies were performed; 1793 (36.8%) were urgent cases and 3077 (63.2%) were elective cases. All cases were started laparoscopically; 25 (0.5%) were converted to open surgery-14 of 1793 (0.78%) urgent cases and 11 of 3077 (0.36%) elective cases. Urgent cholecystectomy took 20 min longer than elective surgery (median 74 versus 52 min). No relevant difference in conversion rate was observed when urgent cholecystectomy was performed within 2 days, between 2 and 4 days, or greater than 4 days from admission (P = 0.197). Median total hospital stay was 4 days.

CONCLUSION

Urgent laparoscopic cholecystectomy is safe and feasible in most patients with acute gall bladder disease. Surgery under the direct care of upper gastrointestinal specialist surgeons is associated with a low conversion rate, low complication rate, and short hospital stay. Timing of surgery has no effect on conversion rate or complication rate.

How can clinicians choose between conflicting and discordant systematic reviews? A replication study of the Jadad algorithm

INTRODUCTION

The exponential growth of published systematic reviews (SRs) presents challenges for decision makers seeking to answer clinical, public health or policy questions. In 1997, an algorithm was created by Jadad et al. to choose the best SR across multiple. Our study aims to replicate author assessments using the Jadad algorithm to determine: (i) if we chose the same SR as the authors; and (ii) if we reach the same results.

METHODS

We searched MEDLINE, Epistemonikos, and Cochrane Database of SRs. We included any study using the Jadad algorithm. We used consensus building strategies to operationalise the algorithm and to ensure a consistent approach to interpretation.

RESULTS

We identified 21 studies that used the Jadad algorithm to choose one or more SRs. In 62% (13/21) of cases, we were unable to replicate the Jadad assessment and ultimately chose a different SR than the authors. Overall, 18 out of the 21 (86%) independent Jadad assessments agreed in direction of the findings despite 13 having chosen a different SR.

CONCLUSIONS

Our results suggest that the Jadad algorithm is not reproducible between users as there are no prescriptive instructions about how to operationalise the algorithm. In the absence of a validated algorithm, we recommend that healthcare providers, policy makers, patients and researchers address conflicts between review findings by choosing the SR(s) with meta-analysis of RCTs that most closely resemble their clinical, public health, or policy question, are the most recent, comprehensive (i.e. number of included RCTs), and at the lowest risk of bias.

Apparent diffusion coefficient by magnetic resonance cholangiopancreatography is useful for grading cholecystitis and surgery planning

INTRODUCTION

Laparoscopic cholecystectomy is a standard procedure for treating cholescytitis, but severe inflammation may cause complications. Our previous study showed that the apparent diffusion coefficient (ADC) values could predict difficult surgery. In the present study, relevance of ADC values in grading the severity of cholecystitis was pathologically investigated.

METHODS

We retrospectively analyzed a total of 50 patients who underwent laparoscopic cholecystectomy or laparotomic cholecystectomy/choledocholithotomy. The degree of inflammation in the neck of the gall bladder was pathologically graded into three tiers (grade 1, mild; grade 2, moderate; grade 3, severe), and ulceration, lymphoid follicle formation, and wall thickness of the gallbladder neck were recorded. All factors were statistically compared with the measured ADC values.

RESULTS

The ADC value was significantly lower in the severe inflammation group ( grade 3) than in the weak inflammation group (grades 1 and 2) (1.93 ± 0.22 vs 2.38 ± 0.67, respectively; P = .02). Ulceration and wall thickness in the gallbladder neck were significantly correlated with ADC values (P = .04 and .006, respectively), and lymphoid follicle formation was marginally correlated with ADC values (P = .06). The diagnostic utility of the ADC values decreased as the interval between imaging and cholecystectomy increased. [Correction added on 19 October 2022, after first online publication: [On the first sentence of the Results section, (grades 2 and 3) for weak inflammation group has been changed to (grades 1 and 2).] CONCLUSION: ADC values were inversely associated with the pathologic intensity of cholecystitis. We recommend that the ADC value be measured before surgery, so that the procedure can be accordingly planned.

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.

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.

Diagnosis-Related Group (DRG)-Based Prospective Hospital Payment System can be well adopted for Acute Care Surgery: Taiwanese Experience with Acute Cholecystitis

BACKGROUND

Laparoscopic cholecystectomy (LC) is a common procedure for cholelithiasis paid by diagnostic-related groups (DRGs) systems. However, acute cholecystitis (AC) patients usually have heterogeneous conditions that compromise the successful implementation of DRGs. We evaluated the quality/efficiency of treating AC patients under the DRG system in Taiwan.

METHODS

All AC patients who underwent LC between October 2015 and December 2016 were included. Patient demographics, treatment outcomes, and financial results were analyzed. Patients were reimbursed by one of the two DRG schemes based on their comorbidities/complications (CC): DRG-1, LC without CC; and DRG-2, LC with CC. Hospitals were reimbursed the costs incurred if they were below the lower threshold (balanced sector); with the outlier threshold if costs were between the lower and outlier thresholds (profitable sector); and with the outlier threshold plus 80% of the exceeding cost if costs were higher than the outlier threshold (profit-losing sector).

RESULTS

Among 246 patients, 114 were paid by DRG-1, and 132 were by DRG-2. In total, 195 of 246 patients underwent LC within 1 day after admission, and patients with mild AC had shorter hospital stays than those with moderate or severe AC. The complication rate was 7.3% with only one mortality. In total, 92.1% of patients in DRG-1 and 90.9% of patients in DRG-2 were profitable. The average margin per patient was 11,032 TWD for DRG-1 and 24,993 TWD for DRG-2.

CONCLUSIONS

DRGs can be well adopted for acute care surgery, and hospitals can still provide satisfactory services without losing profit.

Early laparoscopic cholecystectomy in acute gallbladder perforation: Single-centre experience

Background:

Acute gallbladder perforation (GBP) is associated with significant mortality and morbidity. Percutaneous drainage followed by interval cholecystectomy has been the preferred management. The outcomes of early surgery, especially by laparoscopy, have not been well studied in GBP. We present our experience in early laparoscopic cholecystectomy in GBP.

Methodology:

A retrospective analysis of patients admitted with GBP between April 2014 and December 2018 was done. Clinical presentation, preoperative imaging, surgical procedure, operative findings and the outcomes in these patients were analysed. Video of the surgeries was reviewed in case of the absence of data from the case records.

Results:

Fifteen patients were treated for GBP during the study period. Eleven patients were male, and the mean age was 61 years. Fourteen patients (93.3%) had associated co-morbidities. Systemic inflammatory response syndrome, sepsis, severe sepsis and septic shock were present in 3, 3, 6 and 3 patients, respectively. The location of the collection was gallbladder fossa, pericholecystic, subhepatic and diffuse in 3, 5, 4 and 3 patients, respectively. Intraoperatively, 13 patients were detected to have perforation at the fundus of the gallbladder. Cystic duct stump was managed with clip, endoloop, suturing and external drainage in 7, 2, 5 and 1 patient, respectively. Laparoscopic cholecystectomy was completed in 12 (80%) patients. Retroinfundibular technique was used in 12 (80%) patients. There was one conversion. Two patients required endoscopic retrograde cholangiogram + bile duct stenting, and one was reexplored for cystic artery bleed. There were no mortalities. The median duration of post-operative hospital stay and drain removal was 3 (1–19) and 3 (1–6), respectively.

Conclusion:

Early laparoscopic cholecystectomy in acute GBP is feasible and can be safely performed in centres having sufficient expertise. Retroinfundibular technique of laparoscopic cholecystectomy is useful in tackling frozen Calot's triangle in GBP.

2020 World Society of Emergency Surgery updated guidelines for the diagnosis and treatment of acute calculus cholecystitis

BACKGROUND

Acute calculus cholecystitis (ACC) has a high incidence in the general population. The presence of several areas of uncertainty, along with the availability of new evidence, prompted the current update of the 2016 WSES (World Society of Emergency Surgery) Guidelines on ACC.

MATERIALS AND METHODS

The WSES president appointed four members as a scientific secretariat, four members as an organization committee and four members as a scientific committee, choosing them from the expert affiliates of WSES. Relevant key questions were constructed, and the task force produced drafts of each section based on the best scientific evidence from PubMed and EMBASE Library; recommendations were developed in order to answer these key questions. The quality of evidence and strength of recommendations were reviewed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria (see https://www.gradeworkinggroup.org/ ). All the statements were presented, discussed and voted upon during the Consensus Conference at the 6th World Congress of the World Society of Emergency Surgery held in Nijmegen (NL) in May 2019. A revised version of the statements was voted upon via an online questionnaire until consensus was reached.

RESULTS

The pivotal role of surgery is confirmed, including in high-risk patients. When compared with the WSES 2016 guidelines, the role of gallbladder drainage is reduced, despite the considerable technical improvements available. Early laparoscopic cholecystectomy (ELC) should be the standard of care whenever possible, even in subgroups of patients who are considered fragile, such as the elderly; those with cardiac disease, renal disease and cirrhosis; or those who are generally at high risk for surgery. Subtotal cholecystectomy is safe and represents a valuable option in cases of difficult gallbladder removal.

CONCLUSIONS, KNOWLEDGE GAPS AND RESEARCH RECOMMENDATIONS

ELC has a central role in the management of patients with ACC. The value of surgical treatment for high-risk patients should lead to a distinction between high-risk patients and patients who are not suitable for surgery. Further evidence on the role of clinical judgement and the use of clinical scores as adjunctive tools to guide treatment of high-risk patients and patients who are not suitable for surgery is required. The development of local policies for safe laparoscopic cholecystectomy is recommended.

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.

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.

Controversias en el manejo de la colecistitis aguda tardía

La colecistitis aguda es la inflamación de la vesícula biliar, en la mayoría de los casos, explicada por la presencia de cálculos mixtos o de colesterol que producen obstrucción y desencadenan factores inflamatorios diversos. La colecistectomía por vía laparoscópica se ha convertido en su tratamiento estándar y definitivo. El procedimiento quirúrgico debe realizarse idealmente en las primeras 72 horas después de iniciados los síntomas, lo que habitualmente se denomina como cuadro agudo. Existe controversia sobre cuál es el manejo más adecuado cuando han pasado más de 72 horas del inicio de los síntomas, condición denominada ‘colecistitis aguda tardía’, cuando se considera que el proceso inflamatorio es mayor y, el procedimiento, técnicamente más complejo y peligroso. Para esta condición, se han establecido dos estrategias iniciales de manejo: la cirugía temprana –durante la hospitalización inicial– o el tratamiento conservador con antibióticos para la supuesta resolución completa de la inflamación, es decir, ‘enfriar el proceso’; varias semanas después, se practica una colecistectomía laparoscópica tardía –diferida o electiva–. Existen muchas publicaciones sobre ambas estrategias, en las que se exponen los beneficios y probables complicaciones de cada una; en la actualidad, se sigue debatiendo sobre el momento óptimo para practicar la intervención quirúrgica. Los trabajos más recientes y con mayor peso epidemiológico, resaltan los beneficios de la cirugía temprana pues, aunque las complicaciones intraoperatorias ocurren en las mismas proporciones, la cirugía en la hospitalización inicial reduce los costos, los reingresos y los tiempos hospitalarios. Después de revisar la literatura disponible a favor y en contra, este artículo pretende recomendar el procedimiento temprano, inclusive cuando hayan pasado más de tres días de iniciados los síntomas y, solo en casos muy seleccionados, diferir la cirugía.

Evidence-based Reviews in Surgery: Early Cholecystectomy for Cholecystitis

QUESTION

What are the clinical outcomes of early versus delayed laparoscopic cholecystectomy (LC) in acute cholecystitis with more than 72 hours of symptoms?

DESIGN

A randomized controlled trial.

SETTING

Single center at the University Hospital of Lausanne, Switzerland.

PATIENTS

Eighty-six patients were enrolled in the study that had symptoms of acute cholecystitis lasting more than 72 hours before admission.

INTERVENTION

Patients were randomly assigned to early LC or delayed LC.

MAIN OUTCOME

Primary outcome was overall morbidity following initial diagnosis. Secondary outcomes included total length of stay, duration of antibiotic used, cost, and surgical outcome.

RESULTS

Overall morbidity was lower in early laparoscopic cholecystectomy (ELC) [6 (14%) vs 17 (39%) patients, P = 0.015]. Median total length of stay (4 vs 7 days, P < 0.001) and duration of antibiotic therapy (2 vs 10 days, P < 0.001) were shorter in the ELC group. Total hospital costs were lower in ELC (9349&OV0556; vs 12,361&OV0556;, P = 0.018). Operative time and postoperative complications were similar (91 vs 88 minutes; P = 0.910) and (15% vs 17%; P = 1.000), respectively.

CONCLUSIONS

ELC for acute cholecystitis even beyond 72 hours of symptoms is safe and associated with less overall morbidity, shorter total hospital stay, and duration of antibiotic therapy, as well as reduced cost compared with delayed cholecystectomy.

The association between bowel obstruction and the management of cholelithiasis and cholecystitis in elderly patients: A population-based cohort study

AIMS

This study aimed to evaluate the risk of bowel events among elderly patients treated using only PTGBD (Percutaneous Gallbladder Drainage), or a cholecystectomy on its own, or PTGBD combined with a subsequent cholecystectomy.

METHODS

A retrospective population-based cohort study was conducted with newly diagnosed cholelithiasis and cholecystitis patients who had no bowel obstruction history and were aged over 65 years during the period of January 1, 2000 to December 31, 2010. These patients were placed into 3 separate study cohorts; PTGBD alone, cholecystectomy alone and PTGBD with subsequent laparoscopic cholecystectomy, with the cohort frequencies matched by age and gender. We defined the index date as the time of the initial cholelithiasis and cholecystitis diagnosis date and began observation and suspended follow-up when the patient had either withdrawn from their health insurance, developed bowel obstruction or reached the date of December 31, 2011.

RESULTS

The incidences of bowel obstruction were 24.6, 19.2 and 13.6 per 1000 person-years for PTGBD cohort, cholecystectomy cohort and PTGBD respectively, with a subsequent laparoscopic cholecystectomy cohort. Compared with the PTGBD cohort, (which was adjusted for age, gender, CCI score and laparotomy history), the hazard ratio of bowel obstruction was 0.77 (95% Confidence Interval (CI) = 0.59-1.00) and 0.57 (95% CI = 0.43-0.76) for the cholecystectomy cohort and PTGBD with a subsequent laparoscopic cholecystectomy cohort respectively.

CONCLUSION

For treatment of cholelithiasis and cholecystitis in elderly patients, PTGBD with a subsequent cholecystectomy could benefit patients by providing a lower risk of ileus or intestinal obstruction.

Laparoscopic cholecystectomy combined with Xiaoyanlidan tablets for treatment of acute cholecystitis patients: Curative effect and impact on prognosis and serological indicators

AIM

To observe the curative effect of laparoscopic cholecystectomy combined with Xiaoyanlidan tablets in the treatment of acute cholecystitis as well as its impact on prognosis and serological indicators.

METHODS

One hundred cases of acute cholecystitis treated at Jiaxing Hospital of Traditional Chinese Medicine from January 2017 to December 2017 were randomly divided into an observation group and a control group, with 50 cases in each group. Both groups underwent laparoscopic cholecystectomy, and the observation group was additionally treated with Xiaoyanlidan tablets. The clinical efficacy, incidence of complications, serological indicators [C reactive protein (CRP), procalcitonin (PCT), cancer antigen (CA) 19-9, thyroid-stimulating hormone (TSH), and insulin (Ins)], recurrence rate of choledocholithiasis, and indexes of liver function were observed and compared in the two groups.

RESULTS

The total effective rate of the observation group was 90%,which was significantly higher than that of the control group (76%, P < 0.05).The incidence of postoperative complications in the observation group was 2%, which was significantly lower than that in the control group (16%, P < 0.05). CRP, PCT, CA19-9, TSH, and Ins in the observation group were significantly lower than those in the control group 1 wk after operation (P < 0.05). The incidence of postoperative choledocholithiasis in the observation group was 10%, which was significantly lower than that in the control group (26%, P < 0.05). Glutamic-pyruvic transaminase and aspartate aminotransferase levels in the observation group were significantly lower than those in the control group (P < 0.05).

CONCLUSION

Laparoscopic cholecystectomy combined with Xiaoyan-lidan tablets can effectively improve the inflammatory response, reduce the incidence of postoperative complications, and improve the total effective rate in the treatment of acute cholecystitis.
