Abstract
Bile leaks arise from various causes such as trauma, complications after hepatobiliary surgery, and intrahepatic malignancies or their associated liver-directed treatments. Bile leaks can result in significant morbidity and mortality. Delayed diagnosis is not uncommon due to nonspecific manifestations; therefore, a high clinical suspicion is needed. A multidisciplinary approach for treatment of biliary leaks with prompt referral to tertiary care centers with experienced hepatobiliary surgeons, advanced endoscopists, and interventional radiologists is needed to address these challenging complications. Management of biliary leaks can range from conservative management to open surgical repair. Minimally invasive procedures play a crucial role in biliary leak treatment, and the interventional radiologist can help guide appropriate management on the basis of a clear understanding of the pathophysiology of biliary leaks and a current knowledge of the armamentarium of treatment options. In most cases, a simple diversion of bile to decompress the biliary system may prove effective. However, persistent and high-output biliary leaks require delineation of the source with tailored treatment options to control the leak. This may be done by additional diversions, occluding the source, reestablishing connections, or using a combination of therapies to bridge to more definitive surgical interventions. The authors describe the different treatment options and emphasize the role of interventional radiology. ©RSNA, 2024.

Surgeons vs ChatGPT: Assessment and Feedback Performance Based on Real Surgical Scenarios. JOURNAL OF SURGICAL EDUCATION 2024; 81:960-966. [PMID: 38749814 DOI: 10.1016/j.jsurg.2024.03.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 03/06/2024] [Accepted: 03/15/2024] [Indexed: 06/11/2024]
Abstract
INTRODUCTION Artificial intelligence tools are being progressively integrated into medicine and surgical education. Large language models, such as ChatGPT, could provide relevant feedback aimed at improving surgical skills. The purpose of this study is to assess ChatGPT´s ability to provide feedback based on surgical scenarios. METHODS Surgical situations were transformed into texts using a neutral narrative. Texts were evaluated by ChatGPT 4.0 and 3 surgeons (A, B, C) after a brief instruction was delivered: identify errors and provide feedback accordingly. Surgical residents were provided with each of the situations and feedback obtained during the first stage, as written by each surgeon and ChatGPT, and were asked to assess the utility of feedback (FCUR) and its quality (FQ). As control measurement, an Education-Expert (EE) and a Clinical-Expert (CE) were asked to assess FCUR and FQ. RESULTS Regarding residents' evaluations, 96.43% of times, outputs provided by ChatGPT were considered useful, comparable to what surgeons' B and C obtained. Assessing FQ, ChatGPT and all surgeons received similar scores. Regarding EE's assessment, ChatGPT obtained a significantly higher FQ score when compared to surgeons A and B (p = 0.019; p = 0.033) with a median score of 8 vs. 7 and 7.5, respectively; and no difference respect surgeon C (score of 8; p = 0.2). Regarding CE´s assessment, surgeon B obtained the highest FQ score while ChatGPT received scores comparable to that of surgeons A and C. When participants were asked to identify the source of the feedback, residents, CE, and EE perceived ChatGPT's outputs as human-provided in 33.9%, 28.5%, and 14.3% of cases, respectively. CONCLUSION When given brief written surgical situations, ChatGPT was able to identify errors with a detection rate comparable to that of experienced surgeons and to generate feedback that was considered useful for skill improvement in a surgical context performing as well as surgical instructors across assessments made by general surgery residents, an experienced surgeon, and a nonsurgeon feedback expert.

Abstract
BACKGROUND Iatrogenic bile duct injury (BDI) during cholecystectomy is associated with a complex and heterogeneous management owing to the burden of morbidity until their definitive treatment. This study aimed to define the textbook outcomes (TOs) after BDI with the purpose to indicate the ideal treatment and to improve it management. METHODS We collected data from patients with an BDI between 1990 and 2022 from 27 hospitals. TO was defined as a successful conservative treatment of the iatrogenic BDI or only minor complications after BDI or patients in whom the first repair resolves the iatrogenic BDI without complications or with minor complications. RESULTS We included 808 patients and a total of 394 patients (46.9%) achieved TO. Overall complications in TO and non-TO groups were 11.9% and 86%, respectively (P < .001). Major complications and mortality in the non-TO group were 57.4% and 9.2%, respectively. The use of end-to-end bile duct anastomosis repair was higher in the non-TO group (23.1 vs 7.8, P < .001). Factors associated with achieving a TO were injury in a specialized center (adjusted odds ratio [aOR], 4.01; 95% CI, 2.68-5.99; P < .001), transfer for a first repair (aOR, 5.72; 95% CI, 3.51-9.34; P < .001), conservative management (aOR, 5.00; 95% CI, 1.63-15.36; P = .005), or surgical management (aOR, 2.45; 95% CI, 1.50-4.00; P < .001). CONCLUSION TO largely depends on where the BDI is managed and the type of injury. It allows hepatobiliary centers to identify domains of improvement of perioperative management of patients with BDI.

Abstract
Acute gallbladder diseases are a common surgical emergency faced by General Surgeons that can sometimes be quite challenging. These complex biliary diseases require multifaceted and expeditious care, optimized based on hospital facility and operating room (OR) resources and the expertise of the surgical team. Effective management of biliary emergencies requires two foundational principles: achieving source control while mitigating the risk of injury to the biliary tree and its blood supply. This review article highlights salient literature on seven complex biliary diseases: acute cholecystitis, cholangitis, Mirizzi syndrome, gallstone ileus with cholecystoenteric fistula, gallstone pancreatitis, gall bladder cancer, and post-cholecystectomy bile leak.

Inhibition of PCSK9 prevents and alleviates cholesterol gallstones through PPARα-mediated CYP7A1 activation. Metabolism 2024; 152:155774. [PMID: 38191052 DOI: 10.1016/j.metabol.2023.155774] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 12/28/2023] [Accepted: 12/31/2023] [Indexed: 01/10/2024]
Abstract
BACKGROUND & AIMS Dysregulated cholesterol metabolism is the major factor responsible for cholesterol gallstones (CGS). Proprotein convertase subtilisin/kexin type 9 (PCSK9) plays a critical role in cholesterol homeostasis and its inhibitors secure approval for treating various cholesterol metabolic disorders such as hypercholesterolemia and cardiovascular diseases, but its role in CGS remains unclear. Our study aims to clarify mechanisms by which PCSK9 promotes CGS formation and explore the application of the PCSK9 inhibitor, alirocumab, in preventing and treating CGS. APPROACH & RESULTS The expressions of PCSK9 were notably increased in CGS patients' serum, bile, and liver tissues compared to those without gallstones. Moreover, among CGS patients, hepatic PCSK9 was positively correlated with hepatic cholesterol and negatively correlated with hepatic bile acids (BAs), suggesting PCSK9 was involved in disrupted hepatic cholesterol metabolism related to CGS. Mechanistically, in vitro experiments demonstrated that inhibition of PCSK9 enhanced nuclear expression of PPARα by diminishing its lysosomal degradation and subsequently activated CYP7A1 transcription. Finally, inhibition of PCSK9 prevented CGS formation and dissolved the existing stones in CGS mice by elevating the conversion of cholesterol into BAs through PPARα-mediated CYP7A1 activation. Additionally, serum PCSK9 level may function as a prognostic signature to evaluate the therapeutic efficacy of PCSK9 inhibitors. CONCLUSIONS Inhibition of PCSK9 exerts preventive and therapeutic effects on CGS by activating PPARα-mediated CYP7A1 expression and facilitating the conversion of cholesterol into BAs, which highlights the potential of PCSK9 inhibition as a promising candidate for preventing and treating CGS in clinical applications. IMPACT AND IMPLICATIONS PCSK9 plays a pivotal role in cholesterol metabolism and its inhibitors are approved for clinical use in cardiovascular diseases. Our study observes inhibition of PCSK9 prevents and dissolves CGS by activating PPARα-mediated CYP7A1 expression and facilitating the conversion of cholesterol into BAs. Mechanistically, PCSK9 inhibition enhanced the nuclear expression of PPARα by diminishing its lysosomal degradation and subsequently activated CYP7A1 transcription. Our study sheds light on the new function and mechanism of PCSK9 in CGS, providing a novel preventive and therapeutic target with potential clinical applications.

Abstract
INTRODUCTION This systematic review and meta-analysis aimed to compare clinical outcomes in patients with complicated acute cholecystitis undergoing laparoscopic total vs subtotal cholecystectomy. METHODS This systematic review and meta-analysis was conducted according to PRISMA guidelines and queried PubMed, Embase, ProQuest, Google Scholar, and Cochrane databases from inception to May 2023. The primary outcome was complication rates including common bile duct injury, wound infection, reoperation, bile leak, retained stones, and subhepatic collection, whereas secondary outcomes were in-hospital mortality and hospital length of stay. RESULTS A total of 7 studies with 135,233 cases were included for meta-analysis. Patients who underwent laparoscopic total cholecystectomy had a significantly lower risk of postoperative bile leaks (RR: .15; 95% CI: .03, .80) and subhepatic fluid collection (RR: 0.19; 95% CI: .06, .63) and were 2.94 times less likely to die compared to those who underwent subtotal cholecystectomy (RR .34; 95% CI: .15, .77). Patients who underwent subtotal cholecystectomy had significantly longer hospital length of stay (mean difference 1.0 days; 95% CI: .5 days, 1.4 days). CONCLUSIONS In adult patients presenting with complicated cholecystitis, management with laparoscopic subtotal cholecystectomy presents a unique complication profile with increased risk of postoperative bile leak and subhepatic fluid collection, in-hospital mortality, and longer hospital length-of-stay when used as an alternative approach to laparoscopic total cholecystectomy. Further research into the most appropriate clinical scenarios and patient populations for the use of the subtotal cholecystectomy approach may prove useful in improving its associated outcomes.

Abstract
INTRODUCTION Bile duct injuries (BDI) following laparoscopic cholecystectomy occurs in approximately 0.6% of the cases, often being more severe and complex. Roux-en-Y hepaticojejunostomy (RYHJ) is considered the optimal therapeutic option, with success rates ranging from 75% to 98%. Several series have demonstrated the advancements of the laparoscopic approach for resolving this condition. The objective of this study is to describe our experience in the laparoscopic repair of BDI. METHODS A retrospective, descriptive study was conducted, including patients who underwent laparoscopic repair after BDI. Demographic, clinical, surgical, and postoperative variables were analysed using descriptive statistical analyses. RESULTS Eight patients with BDI underwent laparoscopic repair (out of 81 surgically repaired patients). Women comprised 75% of the sample. A complete laparoscopic repair was achieved in 75% (6) of cases. The mean age was 40.8 ± 16.61 years (range 19-65). Injuries at or above the confluence (Strasberg-Bismuth ≥ E3) occurred in 25% of cases (2). Primary repair was performed in two cases. Half of the cases underwent a Hepp-Couinaud laterolateral RYHJ, while three patients received a terminolateral RYHJ, and one underwent a bi-terminolateral RYH. The mean operative time was 260 min (range 120-360). Overall morbidity was 37.5% (3 cases): two minor complications (bile leak grade A and drainage-related bleeding) and one major complication (bile leak grade C). No mortality was recorded. The maximum follow-up period reached 26 months (range 6-26). CONCLUSIONS Our study demonstrates the feasibility of laparoscopic RYHJ in a selected group of patients, offering the benefits of a minimally invasive approach.

Predictive Factors for Difficult Laparoscopic Cholecystectomies in Acute Cholecystitis. Diagnostics (Basel) 2024; 14:346. [PMID: 38337862 PMCID: PMC10855974 DOI: 10.3390/diagnostics14030346] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 02/02/2024] [Accepted: 02/03/2024] [Indexed: 02/12/2024] Open
Abstract
Laparoscopic cholecystectomy (LC) is the gold standard treatment in acute cholecystitis. However, one in six cases is expected to be difficult due to intense inflammation and suspected adherence to and involvement of adjacent important structures, which may predispose patients to higher risk of vascular and biliary injuries. In this study, we aimed to identify the preoperative parameters with predictive value for surgical difficulties. A retrospective study of 255 patients with acute cholecystitis admitted in emergency was performed between 2019 and 2023. Patients in the difficult laparoscopic cholecystectomy (DLC) group experienced more complications compared to the normal LC group (33.3% vs. 15.3%, p < 0.001). Age (p = 0.009), male sex (p = 0.03), diabetes (p = 0.02), delayed presentation (p = 0.03), fever (p = 0.004), and a positive Murphy sign (p = 0.007) were more frequently encountered in the DLC group. Total leukocytes, neutrophils, and the neutrophil-to-lymphocyte ratio (NLR) were significantly higher in the DLC group (p < 0.001, p = 0.001, p = 0.001 respectively). The Tongyoo score (AUC ROC of 0.856) and a multivariate model based on serum fibrinogen, thickness of the gallbladder wall, and transverse diameter of the gallbladder (AUC ROC of 0.802) showed a superior predictive power when compared to independent parameters. The predictive factors for DLC should be assessed preoperatively to optimize the therapeutic decision.

Abstract
BACKGROUND The surgical difficulty of laparoscopic cholecystectomy (LC) for acute cholecystitis varies from case to case, and appropriate intraoperative evaluation would help prevent bile duct injury (BDI). METHODS We analyzed 178 patients who underwent LC for acute cholecystitis. Expert surgeons and trainees individually evaluated the surgical difficulty. The inter-rater agreement was analyzed using Conger's κ and Gwet's agreement coefficient (AC). Furthermore, we analyzed the predictive surgical difficulty item for performing subtotal cholecystectomy (STC). RESULTS Regarding the inter-rater agreement between expert surgeons and trainees, 15 of the 17 surgical difficulty items had a Gwet's AC of 0.5 or higher, indicating "moderate" agreement or higher. Furthermore, the highest and total surgical difficulty scores were deemed "substantial" agreement. Scarring and dense fibrotic changes around the Calot's triangle area with easy bleeding with/without necrotic changes were predictive of whether STC should be performed. CONCLUSIONS This surgical difficulty grading system is expected to be a tool that can be used by any surgeon with LC experience. STC should be performed to prevent BDI according to the changes around the Calot's triangle area.

A multi-national, video-based qualitative study to refine training guidelines for assigning an "unsafe" score in laparoscopic cholecystectomy critical view of safety. Surg Endosc 2024; 38:983-991. [PMID: 37973638 DOI: 10.1007/s00464-023-10528-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Accepted: 10/12/2023] [Indexed: 11/19/2023]
Abstract
BACKGROUND The critical view of safety (CVS) was incorporated into a novel 6-item objective procedure-specific assessment for laparoscopic cholecystectomy (LC-CVS OPSA) to enhance focus on safe completion of surgical tasks and advance the American Board of Surgery's entrustable professional activities (EPAs) initiative. To enhance instrument development, a feasibility study was performed to elucidate expert surgeon perspectives regarding "safe" vs. "unsafe" practice. METHODS A multi-national consortium of 11 expert LC surgeons were asked to apply the LC-CVS OPSA to ten LC videos of varying surgical difficulty using a "safe" vs. "unsafe" scale. Raters were asked to provide written rationale for all "unsafe" ratings and invited to provide additional feedback regarding instrument clarity. A qualitative analysis was performed on written responses to extract major themes. RESULTS Of the 660 ratings, 238 were scored as "unsafe" with substantial variation in distribution across tasks and raters. Analysis of the comments revealed three major categories of "unsafe" ratings: (a) inability to achieve the critical view of safety (intended outcome), (b) safe task completion but less than optimal surgical technique, and (c) safe task completion but risk for potential future complication. Analysis of reviewer comments also identified the potential for safe surgical practice even when CVS was not achieved, either due to unusual anatomy or severe pathology preventing safe visualization. Based upon findings, modifications to the instructions to raters for the LC-CVS OPSA were incorporated to enhance instrument reliability. CONCLUSIONS A safety-based LC-CVS OPSA has the potential to significantly improve surgical training by incorporating CVS formally into learner assessment. This study documents the perspectives of expert biliary tract surgeons regarding clear identification and documentation of unsafe surgical practice for LC-CVS and enables the development of training materials to improve instrument reliability. Learnings from the study have been incorporated into rater instructions to enhance instrument reliability.

Abstract
AIMS The identification of the anatomical components of the Calot's Triangle during laparoscopic cholecystectomy (LC) might be challenging and its difficulty may increase when a surgical trainee (ST) is in charge, ultimately allegedly affecting also the incidence of common bile duct injuries (CBDIs). There are various methods to help reach the critical view of safety (CVS): intraoperative cholangiogram (IOC), critical view of safety in white light (CVS-WL) and near-infrared fluorescent cholangiography (NIRF-C). The primary objective was to compare the use of these techniques to obtain the CVS during elective LC performed by ST. METHODS This was a multicentre prospective observational study (Clinicalstrials.gov Registration number: NCT04863482). The impact of three different visualization techniques (IOC, CVS-WL, NIRF-C) on LC was analyzed. Operative time and time to achieve the CVS were considered. All the participating surgeons were also required to fill in three questionnaires at the end of the operation focusing on anatomical identification of the general task and their satisfaction. RESULTS Twenty-nine centers participated for a total of 338 patients: 260 CVS-WL, 10 IOC and 68 NIRF-C groups. The groups did not differ in the baseline characteristics. CVS was considered achieved in all the included case. Rates were statistically higher in the NIR-C group for common hepatic and common bile duct visualization (p = 0.046; p < 0.005, respectively). There were no statistically significant differences in operative time (p = 0.089) nor in the time to achieve the CVS (p = 0.626). Three biliary duct injuries were reported: 2 in the CVS-WL and 1 in the NIR-C. Surgical workload scores were statistically lower in every domain in the NIR-C group. Subjective satisfaction was higher in the NIR-C group. There were no other statistically significant differences. CONCLUSIONS These data showed that using NIRF-C did not prolong operative time but positively influenced the surgeon's satisfaction of the performance of LC.

Abstract
BACKGROUND A novel 6-item objective, procedure-specific assessment for laparoscopic cholecystectomy incorporating the critical view of safety (LC-CVS OPSA) was developed to support trainee formative and summative assessments. The LC-CVS OPSA included two retraction items (fundus and infundibulum retraction) and four CVS items (hepatocystic triangle visualization, gallbladder-liver separation, cystic artery identification, and cystic duct identification). The scoring rubric for retraction consisted of poor (frequently outside of defined range), adequate (minimally outside of defined range) and excellent (consistently inside defined range) and for CVS items were "poor-unsafe", "adequate-safe", or "excellent-safe". METHODS A multi-national consortium of 12 expert LC surgeons applied the OPSA-LC CVS to 35 unique LC videos and one duplicate video. Primary outcome measure was inter-rater reliability as measured by Gwet's AC2, a weighted measure that adjusts for scales with high probability of random agreement. Analysis of the inter-rater reliability was conducted on a collapsed dichotomous scoring rubric of "poor-unsafe" vs. "adequate/excellent-safe". RESULTS Inter-rater reliability was high for all six items ranging from 0.76 (hepatocystic triangle visualization) to 0.86 (cystic duct identification). Intra-rater reliability for the single duplicate video was substantially higher across the six items ranging from 0.91 to 1.00. CONCLUSIONS The novel 6-item OPSA LC CVS demonstrated high inter-rater reliability when tested with a multi-national consortium of LC expert surgeons. This brief instrument focused on safe surgical practice was designed to support the implementation of entrustable professional activities into busy surgical training programs. Instrument use coupled with video-based assessments creates novel datasets with the potential for artificial intelligence development including computer vision to drive assessment automation.

Abstract
BACKGROUND The aim of this manuscript is to illustrate a new method permitting safe cholecystectomy in terms of complications with respect to the common bile duct (CBD). METHODS The core of this new technique is identification of the continuity of the cystic duct with the infundibulum. The cystic duct can be identified between the inner gallbladder wall and inflamed outer wall. RESULTS In the last 2 years, from January 2019 until December 2021, 3 patients have been treated with the reported technique without complications. CONCLUSIONS Among the various cholecystectomy procedures, this is a new approach that ensures the safety of the structures of Calot's triangle while providing the advantages gained from total removal of the gallbladder.

Abstract
OBJECTIVE To compare the effects of ampulla-guided realignment and conventional gallbladder triangle anatomy in difficult laparoscopic cholecystectomy (DLC). METHODS From June 2021 to August 2022, data from 100 patients undergoing DLC at Nanjing Hospital of Traditional Chinese Medicine were analyzed retrospectively. Patients were divided into two groups: the experimental group (LC with the ampulla-guided realignment) and the control group (conventional LC with triangular gallbladder anatomy), with 50 patients per group. The intraoperative blood loss, operation time, postoperative drainage tube indwelling time, hospitalization time, bile duct injury rate, operation conversion rate, and incidence of postoperative complications were recorded and compared between the two groups. The pain response and daily activities of the patients in the two groups were evaluated 48 h after the operation. RESULTS The amount of intraoperative blood loss, postoperative drainage tube indwelling time, hospital stay, operation conversion rate, pain degree at 24 and 48 h after operation, bile duct injury incidence, and total postoperative complication rate were shorter or lower in the experimental group than those in the control group (p < 0.05). The Barthel index scores of both groups were higher 48 h after the operation than before the operation, and the experimental group was higher than the control group (p < 0.05). CONCLUSION The ampulla-guided alignment in DLC surgery was more beneficial in promoting postoperative recovery, reducing postoperative pain response, reducing the incidence of postoperative complications, and reducing bile duct injury.

Abstract
Common bile duct (CBD) exploration and T-tube drainage are the main surgical methods for the removal of bile duct stones (BDSs), which can now be completed by laparoscopy. However, the feasibility and safety of primary closure of the CBD (PCCBD) in laparoscopic CBD exploration (LCBDE) without biliary drainage are still uncertain. From January 1, 2021, to June 30, 2022, patients who were diagnosed with BDSs and underwent LCBDE and primary closure of the CBD without biliary drainage in our hospital were included. The clinical and prognostic data of the patients were retrospectively analyzed to determine the feasibility and safety of PCCBD in LCBDE without biliary drainage. Forty-nine patients successfully underwent PCCBD in LCBDE without biliary drainage. The operation time was 158.8 ± 50.3 (90-315,150) minutes, the bile duct suture time was 17.6 ± 4.46 (10-26, 18) minutes, the intraoperative blood loss volume was 70.4 ± 52.6 (5-200, 80) ml, the hospitalization cost was 28,141.2 ± 7011.3 (15,005.45-52,959.34, 26,815.14) CNY Yuan, the hospitalization time was 13.22 ± 5.16 (8-32, 12) days, and the postoperative hospitalization time was 7.31 ± 1.94 (3-15, 7) days. There were 3 cases of postoperative bile leakage (3/49, 6.12%), all of them healed by nonsurgical treatment. During the follow-up of 17.2 ± 11.01 (10-26, 17) months, no residual BDSs, biliary stricture or other complications classified as Clavien-Dindo grade I or higher occurred. For some selected patients who meet certain criteria, PCCBD in LCBDE without biliary drainage is feasible and safe and is more conducive to the rapid postoperative recovery of patients.

Abstract
Objective: Compare the clinical efficacy of anterior and posterior Calot's triangle approach in laparoscopic cholecystectomy (LC) for chronic atrophic cholecystitis, to find out which approach is much safer and more reliable. Patients and Methods: From June 2020 to June 2022, 102 patients with chronic atrophic cholecystitis underwent LC in our hospital. They were divided into anterior Calot's triangle approach group and posterior Calot's triangle approach group. In addition, their clinical data, intraoperative conditions, surgical results, and postoperative recovery were analyzed. Results: LC was performed in 41 females and 28 males by the anterior Calot's triangle approach, and in 20 females and 13 males by the posterior Calot's triangle approach. There were no differences in age, gender, and body mass index between the two groups (P > .05). The probability of rupture of cystic artery between both groups was not significantly different (P = .549), and the intraoperative blood loss was more in the anterior group (P = .014). The operative time of the posterior approach appeared to be shorter (P = .013). Bile duct injury and conversion to open cholecystectomy revealed no significant difference (P > .05). The recovery time of gastrointestinal function, wound infection, white blood cell count, liver function, and postoperative hospital stay time were found to be not significantly different (P > .05). Conclusion: By the posterior Calot's triangle approach, LC is a convenient and feasible surgical procedure for chronic atrophic cholecystitis with less blood loss and can become easier without increasing the risk of surgery.

Abstract
INTRODUCTION Bile duct injuries (BDIs) are a significant source of morbidity among patients undergoing laparoscopic cholecystectomy (LC). GoNoGoNet is an artificial intelligence (AI) algorithm that has been developed and validated to identify safe ("Go") and dangerous ("No-Go") zones of dissection during LC, with the potential to prevent BDIs through real-time intraoperative decision-support. This study evaluates GoNoGoNet's ability to predict Go/No-Go zones during LCs with BDIs. METHODS AND PROCEDURES Eleven LC videos with BDI (BDI group) were annotated by GoNoGoNet. All tool-tissue interactions, including the one that caused the BDI, were characterized in relation to the algorithm's predicted location of Go/No-Go zones. These were compared to another 11 LC videos with cholecystitis (control group) deemed to represent "safe cholecystectomy" by experts. The probability threshold of GoNoGoNet annotations were then modulated to determine its relationship to Go/No-Go predictions. Data is shown as % difference [99% confidence interval]. RESULTS Compared to control, the BDI group showed significantly greater proportion of sharp dissection (+ 23.5% [20.0-27.0]), blunt dissection (+ 32.1% [27.2-37.0]), and total interactions (+ 33.6% [31.0-36.2]) outside of the Go zone. Among injury-causing interactions, 4 (36%) were in the No-Go zone, 2 (18%) were in the Go zone, and 5 (45%) were outside both zones, after maximizing the probability threshold of the Go algorithm. CONCLUSION AI has potential to detect unsafe dissection and prevent BDIs through real-time intraoperative decision-support. More work is needed to determine how to optimize integration of this technology into the operating room workflow and adoption by end-users.

Abstract
BACKGROUND Acute cholecystitis (AC) is one of the most prevalent diseases in clinical practice. Poor surgical candidates may benefit from early percutaneous cholecystostomy (PC) drainage followed by interval cholecystectomy (IC), which is the definitive treatment. The optimal timing between the PC drainage and the IC has not been identified. This study aimed to investigate how the duration between PC and IC affects perioperative outcomes and identify the optimal IC timing to minimize complications. METHODS This retrospective cohort study included all adult patients diagnosed with AC who underwent PC followed by IC at a single institution center between 2014 and 2022. Patients with a history of hepatobiliary surgery, stones in the common bile duct, cirrhosis, active malignancy, or prolonged immunosuppression were excluded. The analysis did not include cases with major concurrent procedures during cholecystectomy, previously aborted cholecystectomies, or failure of the PC drain to control the inflammation. Linear and logistic regression models were used to analyze the impact of the interval between PC and IC on intra- and perioperative outcomes. RESULTS One hundred thirty-two patients (62.1% male) with a mean age of 64.4 ± 15 (mean ± SD) years were diagnosed with AC (25% mild, 47.7% moderate, 27.3% severe). All patients underwent PC followed by IC after a median of 64 [48-91] days. Longer ICU stay was associated with longer time intervals between PC and IC (Coef 105.98, p < 0.001). No significant variations were detected in the intraoperative and perioperative outcomes between patients undergoing IC within versus after 8 weeks from PC placement. However, a higher percentage of patients with delayed IC (after 8 weeks) were discharged home (96.4% vs. 83.7%; p = 0.019). CONCLUSIONS Patients may benefit from undergoing IC after the 8-week cutoff after PC. However, very long periods between PC and IC procedures may increase the risk of longer ICU stay.

Abstract
INTRODUCTION Bile duct injuries avoidance is a key goal of biliary surgery. In this prospective study we evaluate the safety and feasibility of ICG fluorescent cholangiography during laparoscopic cholecystectomy (LC) focusing on the optimization of timing and dose administration. MATERIAL AND METHODS From February to December 2022 fifty-four LC were performed with fluorescence imaging in our surgical department. 2.5 mg ICG were administered intravenously between 5 h and 24 h before surgery. Near-infrared fluorescent cholangiography (NIRF-C) was performed. Adequate fluorescence was evaluated by comparing agent accumulation in the gallbladder and the extrahepatic duct and the background of liver parenchyma. RESULTS Biliary anatomy was identified in all cases. Median time of ICG administration was 11 h previous surgery and three groups of patients were identified: group A receiving ICG 5-9 h, group B 10-14 h, group C 15-24 h before surgery. Peak contrast was gained in group B, with minimal fluorescence of liver parenchyma and more intense visibility of the biliary tract. Intraoperative cholangiogram was unnecessary in all cases. CONCLUSION Fluorescent cholangiography during LC is safe and feasible overcoming the limits of other techniques available. 2.5 mg ICG administered 10-14 h before surgery produces optimal outcomes for near-infrared (NIR) fluorescent cholangiography.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LapC) is one of the most frequently performed surgical procedures worldwide. Reaching technical competency in performing LapC is considered one essential task for young surgeons. Investigating the learning curve for LapC (LC-LapC) may provide important information regarding the learning process and guide the training pathway of residents, improving educational outcomes. The present study aimed to investigate LC-LapC among general surgery residents (GSRs). METHODS Operative surgical reports of consecutive patients undergoing LapC performed by GSRs attending the General Surgery Residency Program at the University of Milan were analysed. Data on patient- and surgery-related variables were obtained from the ICD-9-CM diagnosis codes and gathered. A multidimensional assessment of the LC was performed through Cumulative Sum (CUSUM) and Risk-Adjusted (RA)-CUSUM analysis. RESULTS 340 patients operated by 6 GSRs were collected. The CUSUM and RA-CUSUM graphs based on surgical failures allowed to distinguish two defined phases for all GSRs: an initial phase ending at the peak, so-called learning phase, followed by a phase in which there was a significant decrease in failure incidence, so-called proficiency phase. The learning phase was completed for all GSRs at most within 25 procedures, but the trend of the curves and the number of procedures needed to achieve technical competency varied among operators ranging between 7 and 25. CONCLUSIONS The present study suggested that at most 25 procedures might be sufficient to acquire technical competency in LapC. The variability in the number of procedures needed to complete the LC, ranging between 7 and 25, could be due to the heterogeneous scenarios in which LapC was performed, and deserves to be investigated through a prospective study involving a larger number of GSRs and institutions.

Abstract
INTRODUCTION Cholecystectomy represents one of the most performed surgical procedures. Bile duct injuries (BDIs) are a dangerous complication of this intervention. With the advent of the laparoscopy, the rate of BDIs showed a growing trend that was partially justified by the learning curve of this technique. EVIDENCE ACQUISITION A literature search was conducted on Embase, Medline, and Cochrane databases to identify studies published up to October 2022 that analyzed the intraoperative detection and management of BDIs diagnosed during cholecystectomy. EVIDENCE SYNTHESIS According to the literature, approximately 25% of BDIs is diagnosed during the laparoscopic cholecystectomy. In the clinical suspicion of BDI, an intraoperative cholangiography is performed to confirm it. Complimentary technology, such as near-infrared cholangiography, can be also adopted. Intraoperative ultrasound represents a useful tool to furtherly define the biliary and the vascular anatomy. The proper classification of the type of BDI allows to identify the correct treatment. When a good expertise in hepato-pancreato-biliary surgery is available, a direct repair is performed with good outcomes both in case of simple and complex lesions. When the local resources are limited or there is a lack of dedicated surgical experience, patient referral to a reference center shows better outcomes. In particular, complex vasculo-biliary injuries require a highly specialized treatment. The key elements to transfer the patients are a good documentation of the injury, a proper drainage of the abdomen, and an antibiotic therapy. CONCLUSIONS BDI management requires a proper diagnostic process and prompt treatment to reduce the morbidity and mortality of this feared complication occurring during cholecystectomy.

Abstract
BACKGROUND An increasing body of literature supports subtotal cholecystectomy (STC) in the management of patients with difficult gallbladder anatomy; however, large-scale studies examining outcomes of total cholecystectomy and STC are lacking. METHODS All adults undergoing total cholecystectomy or STC were tabulated from the 2016-2019 Nationwide Readmissions Database. Entropy balancing was performed to adjust for patient differences based on extent of resection. Subsequent multivariable regression models were used to assess the association of STC with major adverse events, postoperative length of stay (pLOS), hospitalization costs, and 30-day non-elective readmission rates. RESULTS Of an estimated 854 357 patients, 7089 (.8%) underwent STC. Compared to total, STC patients were significantly older, less commonly female, and had a higher Elixhauser Index (all P < .001). Both cohorts had similar rates of postoperative ERCP (1.7% vs 1.5%, P = .33); however, the STC cohort had significantly higher utilization of subsequent drainage procedures (1.8% vs .5%, P < .001). After entropy balancing and multivariable risk-adjustment, STC was not associated with greater odds of MAE (AOR 1.11, 95% CI .99-1.23, P = .06). Notably, relative to total, STC was associated with longer pLOS (β .14, 95% CI .11-.17, P < .001) and greater hospitalization costs (β + $1,900, 95% CI 1300-2,500, P < .001). However, the extent of resection was not associated with the likelihood of 30-day non-elective readmission (AOR 1.01, 95% CI .91-1.13, P = .86). DISCUSSION Our findings suggest that STC is a viable, yet resource intensive, option in the management of complex cholecystitis.

Abstract
INTRODUCTION Although laparoscopic cholecystectomy (LC) has been standard of care for symptomatic gallstone disease for almost 30 years, the use of routine intraoperative cholangiogram (IOC) remains controversial. There are marked variations in the use IOC during LC internationally. Debate has continued about its benefit, in part because of inconsistent benefit, time, and resources required to complete IOC. This literature review is presented as a debate to outline the arguments in favour of and against routine IOC in laparoscopic cholecystectomy. METHODS A standard literature review of PubMed, Medline, OVID, EMBASE, CINHIL and Web of Science was performed, specifically for literature pertaining to the use of IOC or alternative intra-operative methods for imaging the biliary tree in LC. Two authors assembled the evidence in favour, and two authors assembled the evidence against. RESULTS From this controversies piece we found that there is little discernible change in the number of BDIs requiring repair procedures. Although IOC is associated with a small absolute reduction in bile duct injury, there are other confounding factors, including a change in laparoscopic learning curves. Alternative technologies such as intra-operative ultrasound, indocyanine green imaging, and increased access to ERCP may contribute to a reduction in the need for routine IOC. CONCLUSIONS In spite of 30 years of accumulating evidence, routine IOC remains controversial. As technology advances, it is likely that alternative methods of imaging and accessing the bile duct will supplant routine IOC.

Abstract
Iatrogenic bile duct injury remains the most severe complication of gallbladder surgeries. To reduce post-operation complication, we introduce an improved approach for bile duct injury repairment, named transhepatic percutaneous cholangial drainage (TPCD) which combined with end-to-end biliary anastomosis. Clinical data obtained from 12 patients between February 2012 and May 2022 were retrospectively analyzed. Patient demographic, clinical, operative, and follow-up data were analyzed using descriptive statistics. All injuries were repaired successfully and no fatal cases occurred. The mean operative time and hospital stay duration were 367.5 ± 103.2 min and 11.3 ± 3.5 days, respectively. In two cases (16.7%), bile leakage occurred at the bile duct anastomosis site. Three patients (25.0%) developed low-grade fever and one patient (8.3%) developed a postoperative infection of the incision site. No postoperative bleeding or bile duct strictures occurred in any of the cases. The patients were followed up from 12 to 122 months (median, 70.5 months). No cholangitis or bile duct restenosis was observed after biliary drainage tube removal. There were no long-term bile duct-related complications seen in the follow-up time. It is safe and feasible for TPCD combined with end-to-end biliary anastomosis using in bile duct injury.

Bile duct injury after cholecystectomy: timing of surgical repair should be based on clinical presentation. The experience of a tertiary referral center with Hepp-Couinaud hepatico-jejunostomy. Updates Surg 2023; 75:1509-1517.

Abstract
Impact of timing of repair on outcomes of patients repaired with Hepp-Couinaud hepatico-jejunostomy (HC-HJ) after bile duct injury (BDI) during cholecystectomy remains debated. This is an observational retrospective study at a tertiary referral hepato-biliary center. HC-HJ was always performed in patients without sepsis or bile leak and with dilated bile ducts. Timing of repair was classified as: early (≤ 2 weeks), intermediate (> 2 weeks, ≤ 6 weeks), and delayed (> 6 weeks). 114 patients underwent HC-HJ between 1994 and 2022: 42.1% underwent previous attempts of repair at referring institutions (Group A) and 57.9% were referred without any attempt of repair before referral (Group B). Overall, a delayed HC-HJ was performed in 78% of patients; intermediate and early repair were performed in 17% and 6%, respectively. In Group B, 10.6% of patients underwent an early, 27.3% an intermediate, and 62.1% a delayed repair. Postoperative mortality was nil. Median follow-up was 106.7 months. Overall primary patency (PP) attainment rate was 94.7%, with a 5- and 10-year actuarial primary patency (APP) of 84.6% and 84%, respectively. Post-repair bile leak was associated with PP loss in the entire population (odds ratio [OR] 9.75, 95% confidence interval [CI] 1.64-57.87, p = 0.012); no correlation of PP loss with timing of repair was noted. Treatment of anastomotic stricture (occurred in 15.3% of patients) was performed with percutaneous treatment, achieving absence of biliary symptoms in 93% and 91% of cases at 5 and 10 years, respectively. BDI can be successfully repaired by HC-HJ regardless of timing when surgery is performed in stable patients with dilated bile ducts and without bile leak.

A comparison between real-time intraoperative voice dictation and the operative report in laparoscopic cholecystectomy: a multicenter prospective observational study. Langenbecks Arch Surg 2023; 408:334. [PMID: 37624422 PMCID: PMC10457217 DOI: 10.1007/s00423-023-03079-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 08/17/2023] [Indexed: 08/26/2023]
Abstract
PURPOSE The current operative report often inadequately reflects events occurring during laparoscopic cholecystectomy (LC). The addition of intraoperative video recording to the operative report has already proven to add important information. It was hypothesized that real-time intraoperative voice dictation (RIVD) can provide an equal or more complete overview of the operative procedure compared to the narrative operative report (NR) produced postoperatively. METHODS SONAR is a multicenter prospective observational trial, conducted at four surgical centers in the Netherlands. Elective LCs of patients aged 18 years and older were included. Participating surgeons were requested to dictate the essential steps of LC during surgery. RIVDs and NRs were reviewed according to the stepwise LC guideline of the Dutch Society for Surgery. The cumulative adequacy rates for RIVDs were compared with those of the postoperatively written NR. RESULTS 79 of 90 cases were eligible for inclusion and available for further analysis. RIVD resulted in a significantly higher adequacy rate compared to NR for the circumferential dissection of the cystic duct and artery (NR 32.5% vs. RIVD 61.0%, P = 0.016). NR had higher adequacy rates in reporting the transection of the cystic duct (NR 100% vs. RIVD 77.9%, P = < 0.001) and the removal of the gallbladder from the liver bed (NR 98.7% vs. RIVD 68.8%, P < 0.001). The total adequacy was not significantly different between the two reporting methods (NR 78.0% vs. RIVD 76.4%, P = 1.00). CONCLUSION Overall, the adequacy of RIVD is comparable to the postoperatively written NR in reporting surgical steps in LC. However, the most essential surgical step, the circumferential dissection of the cystic duct and artery, was reported more adequately in RIVD.

Abstract
The incidence of common bile duct injuries following laparoscopic cholecystectomy (LC) remains three times higher than that following open surgery despite numerous attempts to decrease intraoperative incidents by employing better training, superior surgical instruments, imaging techniques, or strategic concepts. This paper is a narrative review which discusses from a contextual point of view the need to standardise the surgical approach in difficult laparoscopic cholecystectomies, the main strategic operative concepts and techniques, complementary visualisation aids for the delineation of anatomical landmarks, and the importance of cognitive maps and algorithms in performing safer LC. Extensive research was carried out in the PubMed, Web of Science, and Elsevier databases using the terms "difficult cholecystectomy", "bile duct injuries", "safe cholecystectomy", and "laparoscopy in acute cholecystitis". The key content and findings of this research suggest there is high intersocietal variation in approaching and performing LC, in the use of visualisation aids, and in the application of safety concepts. Limited papers offer guidelines based on robust data and a timid recognition of the human factors and ergonomic concepts in improving the outcomes associated with difficult cholecystectomies. This paper highlights the most relevant recommendations for dealing with difficult laparoscopic cholecystectomies.

Abstract
BACKGROUND Misidentification of anatomical structures is one of the most common causes of bile duct injury following laparoscopic cholecystectomy. Achieving Critical View of Safety (CVS) is a standard step in conducting safe cholecystectomy all over the world. In our institute, we achieve CVS via a unique technique called Triple One or 111 and find it very helpful and easy to achieve CVS. Moreover, the rate of conversion has also decreased while achieving CVS via this technique. The unique aspect of the Triple One technique is that by following this method, even new laparoscopic surgeons can achieve CVS very easily in difficult cases and, hence, it decreases the chances of vasculobiliary injury (VBI). OBJECTIVE This study aimed to determine how effective the Triple One technique is in achieving CVS as well as in lessening the chances of VBI. MATERIAL AND METHODS A total of 545 patients were admitted through the outpatient department, ranging in age from 30 to 70 years, with a mean of 50 years. The study comprised patients with American Society of Anaesthesiologists (ASA) I & II, acute and chronic cholecystitis, and symptomatic cholelithiasis. The study excluded patients with co-morbidities, prior abdominal procedures, and suspected complications. On the second postoperative day, all patients received their discharge papers and on the seventh postoperative day, follow-up was completed. RESULTS Successful gallbladder extraction using the Triple One technique was achieved in 540 (99%) cases. The other five (1%) cases converted to open cholecystectomy because of the difficult gallbladder anatomy and extensive scarring. No VBI or bile duct injury was noted. No mortality was recorded during the study period. CONCLUSION By incorporating CVS using the Triple One technique into our policies and curriculum, we may encourage safe cholecystectomy practices and prevent bile duct injuries.

Abstract
BACKGROUND We hypothesized that routine cholangiography during laparoscopic cholecystectomy may increase use of postoperative imaging and invasive testing. METHODS A retrospective review was performed of laparoscopic cholecystectomy cases at 6 community hospitals from 2017 through 2020. For surgeons performing routine vs selective cholangiography, we compared primary outcomes of operative time, 30-day complications, and postoperative imaging or procedures. RESULTS In total, 2359 laparoscopic cholecystectomy procedures were performed. Eighteen surgeons performed routine cholangiography (1125 cases), and 13 performed selective (1234 cases). Mean operative time was longer in the routine group (125.3 vs 98.7 min, P < .001). Between groups, 30-day complications were similar. Two common bile duct injuries were identified in the routine group. Postoperatively, the routine group underwent 2.5 times more imaging and invasive testing (P < .001). CONCLUSIONS In community hospitals, laparoscopic cholecystectomy can be performed safely by surgeons using cholangiography routinely or selectively. Routine cholangiography resulted in more postoperative imaging and invasive testing.

Abstract
INTRODUCTION Surgical studies evaluating a device or technology in comparison to an established surgical technique should accurately report all the important components of the surgical technique in order to reduce the risk of intervention bias. In the debate of visualization of the recurrent laryngeal nerve alone (VONA) versus intraoperative nerve monitoring (IONM) during thyroidectomy, surgical technique plays a key role in both strategies. Our aim was to investigate whether the surgical technique was considered as a risk of intervention bias by relevant meta-analyses and reviews and if steps of surgical intervention were described in their included studies. METHODS We searched PUBMED, CENTRAL-Cochrane library, PROSPERO and GOOGLE for reviews and meta-analyses focusing on the comparison of IONM to VONA in primary open thyroidectomy. Τhen, primary studies were extracted from their reference lists. We developed a typology for surgical technique applied in primary studies and a framework approach for the evaluation of this typology by the meta-analyses and reviews. RESULTS Twelve meta-analyses, one review (388,252 nerves at risk), and 84 primary studies (128,720 patients) were included. Five meta-analyses considered the absence of typology regarding the surgical technique as a source of intervention bias; 48 primary studies (57.14%) provided information about at least one item of the typology components and only 1 for all of them. DISCUSSION Surgical technique of thyroidectomy in terms of a typology is underreported in studies and undervalued by meta-analyses comparing VONA to IONM. This missing typology should be reconsidered in the comparative evaluation of these two strategies.

Impact of AI system on recognition for anatomical landmarks related to reducing bile duct injury during laparoscopic cholecystectomy. Surg Endosc 2023:10.1007/s00464-023-10224-5.

Abstract
BACKGROUND According to the National Clinical Database of Japan, the incidence of bile duct injury (BDI) during laparoscopic cholecystectomy has hovered around 0.4% for the last 10 years and has not declined. On the other hand, it has been found that about 60% of BDI occurrences are due to misidentifying anatomical landmarks. However, the authors developed an artificial intelligence (AI) system that gave intraoperative data to recognize the extrahepatic bile duct (EHBD), cystic duct (CD), inferior border of liver S4 (S4), and Rouviere sulcus (RS). The purpose of this research was to evaluate how the AI system affects landmark identification. METHODS We prepared a 20-s intraoperative video before the serosal incision of Calot's triangle dissection and created a short video with landmarks overwritten by AI. The landmarks were defined as landmark (LM)-EHBD, LM-CD, LM-RS, and LM-S4. Four beginners and four experts were recruited as subjects. After viewing a 20-s intraoperative video, subjects annotated the LM-EHBD and LM-CD. Then, a short video is shown with the AI overwriting landmark instructions; if there is a change in each perspective, the annotation is changed. The subjects answered a three-point scale questionnaire to clarify whether the AI teaching data advanced their confidence in verifying the LM-RS and LM-S4. Four external evaluation committee members investigated the clinical importance. RESULTS In 43 of 160 (26.9%) images, the subjects transformed their annotations. Annotation changes were primarily observed in the gallbladder line of the LM-EHBD and LM-CD, and 70% of these shifts were considered safer changes. The AI-based teaching data encouraged both beginners and experts to affirm the LM-RS and LM-S4. CONCLUSION The AI system provided significant awareness to beginners and experts and prompted them to identify anatomical landmarks linked to reducing BDI.

J Clin Med 2023; 12:3786. [PMID: 37297981 PMCID: PMC10253433 DOI: 10.3390/jcm12113786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 05/18/2023] [Accepted: 05/28/2023] [Indexed: 06/12/2023] Open
Abstract
PURPOSES The management of patients with iatrogenic bile duct injuries (IBDI) is a challenging field, often with dismal medico legal projections. Attempts to classify IBDI have been made repeatedly and the final results were either analytical and extensive but not useful in everyday clinical practice systems, or simple and user friendly but with limited clinical correspondence approaches. The purpose of the present review is to propose a novel, clinical classification system of IBDI by reviewing the relevant literature. METHODS A systematic literature review was conducted by performing bibliographic searches in the available electronic databases, including PubMed, Scopus, and the Cochrane Library. RESULTS Based on the literature results, we propose a five (5) stage (A, B, C, D and E) classification system for IBDI (BILE Classification). Each stage is correlated with the recommended and most appropriate treatment. Although the proposed classification scheme is clinically oriented, the anatomical correspondence of each IBDI stage has been incorporated as well, using the Strasberg classification. CONCLUSIONS BILE classification represents a novel, simple, and dynamic in nature classification system of IBDI. The proposed classification focuses on the clinical consequences of IBDI and provides an action map that can appropriately guide the treatment plan.

Abstract
BACKGROUND Anastomotic stricture is a common underlying cause of long-term morbidity after hepaticojejunostomy (HJ) for bile duct injury (BDI) following cholecystectomy. However, there are no methods for predicting stricture risk. This study was aimed at establishing two online calculators for predicting anastomotic stricture occurrence (ASO) and stricture-free survival (SFS) in this patient population. METHODS The clinicopathological characteristics and follow-up information of patients who underwent HJ for BDI after cholecystectomy from a multi-institutional database were reviewed. Univariate and multivariate analyses of the risk factors of ASO and SFS were performed in the training cohort. Two nomogram-based online calculators were developed and validated by internal bootstrapping resamples ( n =1000) and an external cohort. RESULTS Among 220 screened patients, 41 (18.64%) experienced anastomotic strictures after a median follow-up of 110.7 months. Using multivariate analysis, four variables, including previous repair, sepsis, HJ phase, and bile duct fistula, were identified as independent risk factors associated with both ASO and SFS. Two nomogram models and their corresponding online calculators were subsequently developed. In the training cohort, the novel calculators achieved concordance indices ( C -indices) of 0.841 and 0.763 in predicting ASO and SFS, respectively, much higher than those of the above variables. The predictive accuracy of the resulting models was also good in the internal ( C -indices: 0.867 and 0.821) and external ( C -indices: 0.852 and 0.823) validation cohorts. CONCLUSIONS The two easy-to-use online calculators demonstrated optimal predictive performance for identifying patients at high risk for ASO and with dismal SFS. The estimation of individual risks will help guide decision-making and long-term personalized surveillance.

Abstract
BACKGROUND The rate of bile duct injury in laparoscopic cholecystectomy (LC) continues to be high due to low critical view of safety (CVS) achievement and the absence of an effective quality control system. The development of an intelligent system enables the automatic quality control of LC surgery and, eventually, the mitigation of bile duct injury. This study aims to develop an intelligent surgical quality control system for LC and using the system to evaluate LC videos and investigate factors associated with CVS achievement. MATERIALS AND METHODS SurgSmart, an intelligent system capable of recognizing surgical phases, disease severity, critical division action, and CVS automatically, was developed using training datasets. SurgSmart was also applied in another multicenter dataset to validate its application and investigate factors associated with CVS achievement. RESULTS SurgSmart performed well in all models, with the critical division action model achieving the highest overall accuracy (98.49%), followed by the disease severity model (95.45%) and surgical phases model (88.61%). CVSI, CVSII, and CVSIII had an accuracy of 80.64, 97.62, and 78.87%, respectively. CVS was achieved in 4.33% in the system application dataset. In addition, the analysis indicated that surgeons at a higher hospital level had a higher CVS achievement rate. However, there was still considerable variation in CVS achievement among surgeons in the same hospital. CONCLUSIONS SurgSmart, the surgical quality control system, performed admirably in our study. In addition, the system's initial application demonstrated its broad potential for use in surgical quality control.

Abstract
Although rare, iatrogenic bile duct injury (BDI) after laparoscopic cholecystectomy may be devastating to the patient. The cornerstones for the initial management of BDI are early recognition, followed by modern imaging and evaluation of injury severity. Tertiary hepato-biliary centre care with a multi-disciplinary approach is crucial. The diagnostics of BDI commences with a multi-phase abdominal computed tomography scan, and when the biloma is drained or a surgical drain is put in place, the diagnosis is set with the help of bile drain output. To visualize the leak site and biliary anatomy, the diagnostics is supplemented with contrast enhanced magnetic resonance imaging. The location and severity of the bile duct lesion and concomitant injuries to the hepatic vascular system are evaluated. Most often, a combination of percutaneous and endoscopic methods is used for control of contamination and bile leak. Generally, the next step is endoscopic retrograde cholangiography (ERC) for downstream control of the bile leak. ERC with insertion of a stent is the treatment of choice in most mild bile leaks. The surgical option of re-operation and its timing should be discussed in cases where an endoscopic and percutaneous approach is not sufficient. The patient's failure to recover properly in the first days after laparoscopic cholecystectomy should immediately raise suspicion of BDI and this merits immediate investigation. Early consultation and referral to a dedicated hepato-biliary unit are essential for the best outcome.

Abstract
BACKGROUND There are no prediction models for bile leakage associated with subtotal cholecystectomy (STC). Therefore, this study aimed to generate a multivariable prediction model for post-STC bile leakage and evaluate its overall performance. METHODS We analysed prospectively managed data of patients who underwent STC by a single consultant surgeon between 14 May 2013 and 21 December 2021. STC was schematised into four variants with five subvariants and classified broadly as closed-tract or open-tract STC. A contingency table was used to detect independent risk factors for bile leakage. A multiple logistic regression analysis was used to generate a model. Discrimination and calibration statistics were computed to assess the accuracy of the model. RESULTS A total of 81 patients underwent the STC procedure. Twenty-eight patients (35%) developed bile leakage. Of these, 18 patients (64%) required secondary surgical intervention. Multivariable logistic regression revealed two independent predictors of post-STC bile leak: open-tract STC (odds ratio [OR], 7.07; 95% confidence interval [CI], 2.191-25.89; P = 0.0170) and acute cholecystitis (OR, 5.449; 95% CI, 1.584-23.48; P = 0.0121). The area under the receiver-operating characteristic curve was 82.11% (95% CI, 72.87-91.34; P < 0.0001). Tjur's pseudo-R2 was 0.3189 and the Hosmer-Lemeshow goodness-of-fit statistic was 4.916 (P = 0.7665). CONCLUSIONS Open-tract STC and acute cholecystitis are the most reliable predictors of bile leakage associated with STC. Future prospective, multicentre studies with higher statistical power are needed to generate more specific and externally validated prediction models for post-STC bile leaks.

Abstract
Background Defining critical view of safety (CVS) is one of the most crucial steps during laparoscopic cholecystectomy (LC). This study aimed to determine the preoperative predictors of failure to achieve CVS during LC. Methods All patients undergoing LC from December 2020 to July 2022 were prospectively included. Results There were 180 females and 93 males. CVS was achieved during LC in 238 (87.2%) patients. Conversion to open surgery was performed for 11 patients. Bile leak occurred in three patients which resolved spontaneously. No patient developed bile duct injury. On univariate analysis, age, male sex, American Society of Anaesthesiologists (ASA) grading, Murphy's sign, emergency surgery, neutrophil percentage, lymphocyte percentage, gallbladder wall thickness > 3mm, and impacted gallstone on abdominal ultrasound were predictors of failure to achieve CVS. On multivariate analysis, neutrophil and lymphocyte percentages were independent predictors of failure to achieve CVS. Patients in whom CVS could not be achieved had significantly longer operative time, higher blood loss, complications, and hospital stays. Discussion Inability to achieve CVS during LC can be predicted preoperatively using various parameters including neutrophil and lymphocyte percentages. Such cases must be operated by senior surgeons or referred to experienced general or hepatobiliary surgeons for cholecystectomy to avoid bile duct injury. The proposed algorithm can help in intraoperative decision-making in difficult cases.

Abstract
BACKGROUND Principles of safe cholecystectomy include dissection of the hepatocystic triangle and identification of the bilio-vascular structures to achieve critical view of safety. The aim of the present study was to document the variations in anatomical landmarks and bilio-vascular structures exposed during laparoscopic cholecystectomy. METHODS All consecutive patients who underwent laparoscopic cholecystectomy were included in the study. Recommended techniques of safe cholecystectomy were followed. Rouviere's sulcus was classified into four types. Cystic duct was assessed for its length and diameter. A new classification was suggested for cystic artery. RESULTS Five hundred patients were included in the study. Critical view of safety was achieved in 463 (92.6%) patients. Type1 Rouviere's sulcus was the most common variant found in 263 (52.6%). Normal cystic duct was present in 339 (67.8%). Wide cystic duct of normal length was the most common variant found in 71 (14.2%). Single cystic artery supero-medial to cystic duct (type1-s) was the most common variant found in 384 (76.8%). Inferior cystic artery i.e. artery infero-lateral to cystic duct (type-2) was the second most common variant, found in 40 (8%). Multiple cystic arteries in the hepatocystic triangle were due either to early division of single cystic artery (type-1m) or double cystic artery (type-3). Aberrant right hepatic artery giving off a small cystic artery (type-4) was seen in 12 (2.4%). CONCLUSION Wide variation in the anatomical structures is noted when principles of safe laparoscopic cholecystectomy is followed. Awareness is paramount to avoid bilio-vascular injury during surgery.

Abstract
BACKGROUND Bile duct injury (BDI) following cholecystectomy is associated with malpractice litigation. Aim of this study was to evaluate risk factors for litigation in patients with BDI referred in a tertiary care center. METHODS Patients treated for BDI between 1994 and 2016. Stabilized inverse probability therapy weighting was used and multivariable logistic regression analysis identified risk factors for malpractice litigation. RESULTS Of the 211 treated patients, 98 met the inclusion criteria: early-referral group (<20 days; 51.0%), late-referral (≥20 days; 49.0%). 36 patients (36.7%) initiated malpractice litigation with verdict in favor of plaintiff in 86.7% of cases (median payment = €90 500, up to €600 000). Attempts at surgical and endoscopic repair before referral were significantly higher in late-referral group. Failed postoperative management (delayed referral, attempts at repair before referral) was one of the strongest predictors for litigation. Risk of litigation progressively increased from 23.8%, when referral time was within 19 days, to 54.5% (61-120 days), to 60.0% (121-210 days) and to 65.1% (211-365 days). DISCUSSION Litigation rate after BDI was 37%. Delayed referral to tertiary care center was one of the strongest predictors for litigation. Prompt referral to tertiary experienced centers without any attempt at repair may reduce the risk of litigation.

Abstract
BACKGROUND Since the introduction of the Critical View of Safety approach in laparoscopic cholecystectomy, exposure of the common bile duct, and common hepatic duct is not recommended, therefore, the length of the cystic duct remnant is no longer controlled. The aim of this case‒control study is to evaluate the relationship between the length of the cystic duct remnant and the risk for bile duct stone recurrence after cholecystectomy. METHODS All MRIs with dedicated sequences of the biliary tract taken between 2010 and 2020 from patients who underwent prior cholecystectomy were reviewed. The length of the cystic duct remnant was measured and compared between the patients with and without bile duct stones using multivariate logistic regression analysis. RESULTS A total of 362 patients were included in this study, 23.5% of whom had bile duct stones on MRI. The cystic duct remnant was significantly longer in the patients with stones than in the control group (median 31 mm versus 18 mm, P < 0.001). In the MRIs performed > 2 years after cholecystectomy, the cystic duct remnant was also significantly longer in the patients with bile duct stones (median 32 mm versus 21 mm, P < 0.001). A cystic duct remnant ≥ 15 mm in length increased the odds of stones (OR = 2.3, P = 0.001). Overall, the odds of bile duct stones increased with an increasing cystic duct remnant length (≥ 45 mm, OR = 5.0, P < 0.001). CONCLUSIONS An excessive cystic duct remnant length increases the odds of recurrent bile duct stones after cholecystectomy.

Abstract
BACKGROUND Many surgical adverse events, such as bile duct injuries during laparoscopic cholecystectomy (LC), occur due to errors in visual perception and judgment. Artificial intelligence (AI) can potentially improve the quality and safety of surgery, such as through real-time intraoperative decision support. GoNoGoNet is a novel AI model capable of identifying safe ("Go") and dangerous ("No-Go") zones of dissection on surgical videos of LC. Yet, it is unknown how GoNoGoNet performs in comparison to expert surgeons. This study aims to evaluate the GoNoGoNet's ability to identify Go and No-Go zones compared to an external panel of expert surgeons. METHODS A panel of high-volume surgeons from the SAGES Safe Cholecystectomy Task Force was recruited to draw free-hand annotations on frames of prospectively collected videos of LC to identify the Go and No-Go zones. Expert consensus on the location of Go and No-Go zones was established using Visual Concordance Test pixel agreement. Identification of Go and No-Go zones by GoNoGoNet was compared to expert-derived consensus using mean F1 Dice Score, and pixel accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). RESULTS A total of 47 frames from 25 LC videos, procured from 3 countries and 9 surgeons, were annotated simultaneously by an expert panel of 6 surgeons and GoNoGoNet. Mean (± standard deviation) F1 Dice score were 0.58 (0.22) and 0.80 (0.12) for Go and No-Go zones, respectively. Mean (± standard deviation) accuracy, sensitivity, specificity, PPV and NPV for the Go zones were 0.92 (0.05), 0.52 (0.24), 0.97 (0.03), 0.70 (0.21), and 0.94 (0.04) respectively. For No-Go zones, these metrics were 0.92 (0.05), 0.80 (0.17), 0.95 (0.04), 0.84 (0.13) and 0.95 (0.05), respectively. CONCLUSIONS AI can be used to identify safe and dangerous zones of dissection within the surgical field, with high specificity/PPV for Go zones and high sensitivity/NPV for No-Go zones. Overall, model prediction was better for No-Go zones compared to Go zones. This technology may eventually be used to provide real-time guidance and minimize the risk of adverse events.

Abstract
Background: Common bile duct (CBD) stones associated with cholecystitis can be treated by single-stage CBD exploration at the time of cholecystectomy or a two-stage approach with endoscopic stone extraction before or after cholecystectomy. The ideal management remains a matter of debate. The aim of this study is to analyze our outcomes with transcystic laparoscopic common bile duct exploration (LCBDE). Material and Methods: A retrospective review of patients who underwent transcystic LCBDE between 2015 and 2019 was performed. Results: A total of 106 patients underwent transcystic LCBDE over 5 years. We performed 1192 laparoscopic cholecystectomies with cholangiograms from March 2015 to December 2019. Fifteen patients had a preoperative endoscopic retrograde cholangiopancreatography (ERCP) for CBD stones seen on magnetic resonance cholangiopancreatography that during laparoscopic cholecystectomy with intraoperative cholangiogram (IOC), there were stones and/or sludge found in the CBD, which required clearance through a transcystic approach. Of the 91 patients who did not have a preoperative ERCP, clearance of the CBD was successful through a transcystic approach in 78 patients (86%). In the 13 patients that intraoperative clearance was not achieved (n = 13, 14%), a postoperative ERCP was performed. A total of 28 patients underwent either pre- or postoperative ERCP (n = 28, 26%). Choledochotomy was not performed in any of the patients. The mean operative time was 127 minutes (127 ± 48). The mean hospital length of stay (LOS) was 4 days (3.9 ± 2.8) with a median LOS of 3 days. Complications observed include wound infection (n = 2, 2%), pancreatitis after ERCP (n = 1, 1%), pneumonia (n = 1, 1%), and right hepatic duct injury (n = 1, 1%). Conclusion: Transcystic LCBDE is an effective and safe option for treatment of CBD stones. While a transcystic approach does not guarantee clearance of the CBD, it avoids the morbidity associated with a choledochotomy and can often prevent patients from having to undergo an additional procedure.

Review of the Literature on Partial Resections of the Gallbladder, 1898-2022: The Outline of the Conception of Subtotal Cholecystectomy and a Suggestion to Use the Terms 'Subtotal Open-Tract Cholecystectomy' and 'Subtotal Closed-Tract Cholecystectomy'. J Clin Med 2023; 12:jcm12031230. [PMID: 36769878 PMCID: PMC9917859 DOI: 10.3390/jcm12031230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 01/29/2023] [Accepted: 02/01/2023] [Indexed: 02/05/2023] Open
Abstract
Current descriptions of the history of subtotal cholecystectomy require more details and accuracy. This study presented a narrative review of the articles on partial resections of the gallbladder published between 1898 and 2022. The Scale for the Assessment of Narrative Review Articles items guided the style and content of this paper. The systematic literature search yielded 165 publications. Of them, 27 were published between 1898 and 1984. The evolution of the partial resections of the gallbladder began in the last decade of the 19th century when Kehr and Mayo performed them. The technique of partial resection of the gallbladder leaving the hepatic wall in situ was well known in the 3rd and 4th decades of the 20th century. In 1931, Estes emphasised the term 'partial cholecystectomy'. In 1947, Morse and Barb introduced the term 'subtotal cholecystectomy'. Madding and Farrow popularised it in 1955-1959. Bornman and Terblanche revitalised it in 1985. This term became dominant in 2014. From a subtotal cholecystectomy technical execution perspective, it is either a single-stage (when it includes only the resectional component) or two-stage (when it also entails closure of the remnant of the gallbladder or cystic duct) operation. Recent papers on classifications of partial resections of the gallbladder indicate the extent of gallbladder resection. Subtotal cholecystectomy is an umbrella term for incomplete cholecystectomies. 'Subtotal open-tract cholecystectomy' and 'subtotal closed-tract cholecystectomy' are terms that characterise the type of completion of subtotal cholecystectomy.

Abstract
INTRODUCTION Bile duct injury (BDI) continues to occur despite technological advances and improvements in surgical training over the past 2 decades. This study was conducted to audit our data on laparoscopic cholecystectomies performed over the past 2 decades to determine the role of Critical View of Safety (CVS) and proctored preceptorship in preventing BDI and postoperative complications. MATERIALS AND METHODS All patients undergoing elective laparoscopic cholecystectomy were analyzed retrospectively. The data were obtained from a prospectively maintained database from January 2004 to December 2019. Proctored preceptorship was used in all cases. Intraoperative details included the number of patients where CVS was defined, number of BDI and conversions. Postoperative outcomes, including hospital stay, morbidity, and bile duct stricture, were noted. RESULTS Three thousand seven hundred twenty-six patients were included in the final analysis. Trainee surgeons performed 31.6% of surgeries and 9.5% of these surgeries were taken over by the senior surgeon. A CVS could be delineated in 96.6% of patients. The major BDI rate was only 0.05%. CONCLUSION This study reiterates the fact that following the basic tenets of safe laparoscopic cholecystectomy, defining and confirming CVS, and following proctored preceptorship are critical in preventing major BDI.

SAGES safe cholecystectomy modules improve practicing surgeons' judgment: results of a randomized, controlled trial. Surg Endosc 2023; 37:862-870. [PMID: 36006521 DOI: 10.1007/s00464-022-09503-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 07/23/2022] [Indexed: 10/15/2022]
Abstract
BACKGROUND Despite the advantages of laparoscopic cholecystectomy, major bile duct injury (BDI) rates during this operation remain unacceptably high. In October 2018, SAGES released the Safe Cholecystectomy modules, which define specific strategies to minimize the risk of BDI. This study aims to investigate whether this curriculum can change the knowledge and behaviors of surgeons in practice. METHODS Practicing surgeons were recruited from the membership of SAGES and the American College of Surgeons Advisory Council for Rural Surgery. All participants completed a baseline assessment (pre-test) that involved interpreting cholangiograms, troubleshooting difficult cases, and managing BDI. Participants' dissection strategies during cholecystectomy were also compared to the strategies of a panel of 15 experts based on accuracy scores using the Think Like a Surgeon validated web-based platform. Participants were then randomized to complete the Safe Cholecystectomy modules (Safe Chole module group) or participate in usually scheduled CME activities (control group). Both groups completed repeat assessments (post-tests) one month after randomization. RESULTS Overall, 41 participants were eligible for analysis, including 18 Safe Chole module participants and 23 controls. The two groups had no significant differences in pre-test scores. However, at post-test, Safe Chole module participants made significantly fewer errors managing BDI and interpreting cholangiograms. Safe Chole module participants were less likely to convert to an open operation on the post-test than controls when facing challenging dissections. However, Safe Chole module participants displayed a similar incidence of errors when evaluating adequate critical views of safety. CONCLUSIONS In this randomized-controlled trial, the SAGES Safe Cholecystectomy modules improved surgeons' abilities to interpret cholangiograms and safely manage BDI. Additionally, surgeons who studied the modules were less likely to convert to open during difficult dissections. These data show the power of the Safe Cholecystectomy modules to affect practicing surgeons' behaviors in a measurable and meaningful way.

Abstract
INTRODUCTION At present, the pre- and postdissection regions during laparoscopic cholecystectomy (LC) are uniformly described by the term "hepatocystic triangle" (HCT). It is unclear whether a distinction needs to be made. An observational study was undertaken to evaluate the predissection hepatocystic region (pre-HCR) and the postdissection hepatocystic region (post-HCR). Also, the dissection-related changes to the contents of the pre-HCR ("proper HCT") were evaluated. METHODS A retrospective review of a prospectively maintained database was done. The operative videos of patients who underwent fluorescence-guided surgery from December 2021 to February 2022 were reviewed. Patients with gallstone disease without complications (GSD) were included in the study. Exclusion criteria were acute cholecystitis, choledocholithiasis, biliary pancreatitis, biliary fistulas, and gallbladder wall thickening of ≥3 mm on ultrasonography. RESULTS Thirteen patients underwent LC for GSD using standard dissection methods. The boundaries of the pre-HCR were identified before dissection in all patients. The dissection resulted in a quadrangular space lateral to the "proper HCT" in all. The post-HCR contained the undissected "proper-HCT" and the quadrangular space in all. The post-HCR area was 4.4 times that of the pre-HCR (3.2-13.1). The peritoneum over the "proper HCT" was unbreached in all patients, and the target structures were delineated outside of it. A critical view of safety (CVS) was demonstrated outside of the "proper HCT" in all patients. CONCLUSION During near-infrared fluorescence-guided LC for GSD, there is no fat clearance in the "HCT." The hepatocystic region before and at the conclusion were distinctly different. The uniform usage of the term "HCT" does not convey this change.
