Abstract
BACKGROUND Although findings from drip infusion cholangiography with computed tomography (DIC-CT) are useful in preoperative anatomic evaluation for laparoscopic cholecystectomy (LC), their relationship with intraoperative surgical difficulty based on the difficulty score (DS) proposed by Tokyo Guidelines 2018 is unclear. We examined this relationship. METHODS Data were collected from 202 patients who underwent LC for benign gallbladder (GB) disease with preoperative DIC-CT in our department. DIC-CT findings were classified into GB-positive and GB-negative groups based on GB opacification, and clinical characteristics were compared. DS assessed only on findings from around Calot's triangle was considered "cDS", and patients were divided into cDS ≤2 and ≥3 groups. Preoperative data including DIC-CT findings were evaluated using multivariate analysis. RESULTS DIC-CT findings showed 151 (74.8%) GB-positive and 51 (25.2%) GB-negative patients. Surgical outcomes were significantly better in the GB-positive versus GB-negative group for operation time (107 vs. 154 min, p < .001), blood loss (8 vs. 25 mL, p < .001), cDS (0.8 vs. 2.2, p < .001), and critical view of safety score (4.0 vs. 3.1, p < .001). cDS was ≤2 in 174 (86.1%) and ≥3 in 28 (13.9%) patients. By multivariate analysis, DIC-CT findings and alkaline phosphatase values were independent factors predicting intraoperative difficulty. CONCLUSION DIC-CT findings are useful for predicting cDS in LC.

Abstract
BACKGROUND Gaming can serve as an educational tool to allow trainees to practice surgical decision-making in a low-stakes environment. LapBot is a novel free interactive mobile game application that uses artificial intelligence (AI) to provide players with feedback on safe dissection during laparoscopic cholecystectomy (LC). This study aims to provide validity evidence for this mobile game. METHODS Trainees and surgeons participated by downloading and playing LapBot on their smartphone. Players were presented with intraoperative LC scenes and required to locate their preferred location of dissection of the hepatocystic triangle. They received immediate accuracy scores and personalized feedback using an AI algorithm ("GoNoGoNet") that identifies safe/dangerous zones of dissection. Player scores were assessed globally and across training experience using non-parametric ANOVA. Three-month questionnaires were administered to assess the educational value of LapBot. RESULTS A total of 903 participants from 64 countries played LapBot. As game difficulty increased, average scores (p < 0.0001) and confidence levels (p < 0.0001) decreased significantly. Scores were significantly positively correlated with players' case volume (p = 0.0002) and training level (p = 0.0003). Most agreed that LapBot should be incorporated as an adjunct into training programs (64.1%), as it improved their ability to reflect critically on feedback they receive during LC (47.5%) or while watching others perform LC (57.5%). CONCLUSIONS Serious games, such as LapBot, can be effective educational tools for deliberate practice and surgical coaching by promoting learner engagement and experiential learning. Our study demonstrates that players' scores were correlated to their level of expertise, and that after playing the game, most players perceived a significant educational value.

Management and patient outcomes following admission with acute cholecystitis in Ireland: A national registry-based study. Surgeon 2024:S1479-666X(24)00085-4. [PMID: 39142970 DOI: 10.1016/j.surge.2024.08.004] [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: 12/14/2023] [Revised: 06/25/2024] [Accepted: 08/05/2024] [Indexed: 08/16/2024]
Abstract
INTRODUCTION Acute cholecystitis is a common general surgical emergency, accounting for 3-10 % of all patients attending with acute abdominal pain. International guidelines suggest that emergency cholecystectomy is the treatment of choice for uncomplicated acute cholecystitis where feasible. There is a paucity of published data on the uptake of emergency cholecystectomy in Ireland. AIM The aim of this study was to evaluate the management of acute cholecystitis in Ireland and to establish the rate of emergency cholecystectomy performed. METHODS All patients with acute cholecystitis presenting to public hospitals in Ireland between January 2017 and July 2023 were identified using the National Quality Assurance and Improvement System (NQAIS). Data were collected on patient demographics, co-morbidities, length of stay, operative intervention, endoscopic intervention, critical care admissions, in-patient mortality, and readmissions. Propensity score matched analysis and logistic regression were performed to account for selection bias in comparing patients managed with cholecystectomy and those managed conservatively. RESULTS 20,886 admission episodes were identified involving 17,958 patients. 3585 (20 %) patients underwent emergency cholecystectomy in total. 3436 (96 %) of these were performed laparoscopically, with 140 (4 %) requiring conversion to an open procedure, and common bile duct injuries occurring in 4 (0.1 %) of patients. In comparison to patients treated conservatively, patients who underwent cholecystectomy were younger (median 50 v 60 years, p < 0.001) and more likely to be female (64 % v 55 % p < 0.001). Following propensity score matched analysis, those who had an emergency cholecystectomy had reduced length of stay (LOS) (median 5 days (IQR 3-8) v 6 days (interquartile range (IQR) 3-10), p < 0.001) and fewer readmissions to hospital (282 (8 %) v 492 (14 %), p < 0.001). On logistic regression, age >65 (OR 1.526), CCI >3 (OR 2.281) and non-operative management (OR 1.136) were significant risk factors for adverse outcome. CONCLUSION Uptake of emergency cholecystectomy in Ireland remains low, and is carried out on a younger, fitter cohort of patients. In those patients, however, it is associated with improved outcomes for cholecystitis compared to conservative management, including shorter LOS and reduced readmission rates for matched cohorts.

Abstract
Backgrounds Laparoscopic cholecystectomy (LC) is the gold standard for surgical removal of gallbladder today. In challenging cholecystectomy cases, conversion to an open technique may be necessary. Therefore, the preoperative prediction of conversion to open technique holds significant importance for patient safety and surgical strategy. In the literature, conversion to open cholecystectomy has been associated with many contradictory predictive factors. The aim of this study is to identify and comprehensively evaluate the predictive laboratory parameters and ratios associated with the conversion from laparoscopic to open cholecystectomy. Methods In this historical cohort study, the data of patients who were scheduled for and underwent LC between January 1, 2018, and September 1, 2023, were retrospectively evaluated. The preoperative laboratory findings and surgical notes of the patients were reviewed retrospectively from the archives. The correlation between patient data and the cholecystectomy groups was analyzed, and comparisons were made between the groups. Results All 160 patients initially underwent a laparoscopic approach. In emergency cases, a statistically significant association was found between lymphocyte count (p = 0.017) and lymphocyte-to-monocyte ratio (LMR) (p = 0.041) with operations completed laparoscopically and between neutrophil-to-lymphocyte ratio (NLR) (p = 0.007) and Systemic Inflammatory Response Index (SIRI) (p = 0.031) with operations converted to open surgery. In elective cases, gamma-glutamyl transferase (GGT) (p = 0.024) and total bilirubin (TBIL) (p = 0.003) were found to have a statistically significant association with operations converted to open surgery. In the logistic regression analysis, hematological parameters and ratios were not found to have a statistically significant relationship in predicting the conversion to open surgery. Conclusion Although significant differences were observed in laboratory parameters and derived ratios such as the NLR and LMR, logistic regression analysis did not identify any of these measures as significant predictors of conversion from laparoscopic to open surgery. Further prospective studies with larger sample sizes are needed in this area.

Abstract
Laparoscopic cholecystectomy (LC) is the gold standard technique for gallbladder diseases in both emergency and elective surgery. The incidence of the disease related to an increasingly elderly population coupled with the efficacy and safety of LC treatment resulted in an increase in the frequency of interventions without an increase in surgical mortality. For these reasons, managers implement strategies by which to standardize the process of patients undergoing LC. Specifically, the goal is to ensure, in accordance with the guidelines of the Italian Ministry of Health, a reduction in post-operative length of stay (LOS). In this study, a Lean Six Sigma (LSS) methodological approach was implemented to identify and subsequently investigate, through statistical analysis, the effect that corrective actions have had on the post-operative hospitalization for LC interventions performed in a University Hospital. The analysis of the process, which involved a sample of 478 patients, with an approach guided by the Define, Measure, Analyze, Improve, and Control (DMAIC) cycle, made it possible to reduce the post-operative LOS from an average of 6.67 to 4.44 days. The most significant reduction was obtained for the 60-69 age group, for whom the probability of using LC is higher than for younger people. The LSS offers a methodological rigor that has allowed us, as already known, to make significant improvements to the process, standardizing the result by limiting the variability and obtaining a total reduction of post-operative LOS of 67%.

Abstract
INTRODUCTION Laparoscopy has a clear patient benefit related to postoperative morbidity but may not be as commonly performed in low-and middle-income countries. The decision to convert to laparotomy can be complex and involve factors related to the surgeon, patient, and procedure. The objective of this work is to analyze the factors associated with conversion in laparoscopic surgery in a low-resource setting. METHODS This is a single-center prospective study of patients who underwent laparoscopic surgery between May 1, 2018 and October 31, 2021. The parameters studied were age, sex, body mass index (BMI), intraoperative complication (e.g., accidental enterotomy, hemorrhage), equipment malfunction (e.g., technical failure of the equipment, break in CO2 supply line), operating time, and conversion rate. RESULTS A total of 123 laparoscopic surgeries were performed. The average age of patients was 31.2 years (range 11-75). The procedures performed included appendix procedures (48%), followed by gynecological (18.7%), gallbladder (14.6%), digestive (10.56%), and abdominal procedures (4%). The average length of hospitalization was 3 days (range 1-16). Conversion to laparotomy was reported in 8.9% (n = 11) cases. Equipment malfunction was encountered in 9.8% (n = 12) cases. Surgical complications were noted in 11 cases (8.9%). Risk factors for conversion were shown to be BMI > 25 kg/m2 (OR 4.6; p = 0.034), intraoperative complications (OR 12.6; p = 0.028), and equipment malfunction (OR 9.4; p = 0.002). CONCLUSION A better understanding of the underlying factors associated with high conversion rates, such as overweight/obesity, intraoperative complications, and equipment failure, is the first step toward surgical planning to reduce postoperative morbidity in low-resource settings.

Abstract
Cholecystectomy is a common surgical procedure performed worldwide for acute cholecystitis. Acute cholecystitis occurs when the cystic duct is obstructed by a gallstone, which causes gallbladder distension and subsequent inflammation of the gallbladder. Acute cholecystitis is characterized by pain in the right upper quadrant, anorexia, nausea, fever, and vomiting. Cholecystectomy is the treatment of choice for acute cholecystitis. The two commonly performed types of cholecystectomies are open cholecystectomy and laparoscopic cholecystectomy. However, the approach of choice widely fluctuates with regard to various factors such as patient history and surgeon preference. It is imperative to understand the variations in outcomes of different approaches and how best they fit an individual patient when deciding the technique to be undertaken. This article reviews several studies and compares the two techniques in terms of procedure, mortality rate, complication rate, bile leak/injury rate, conversion rate, and bleeding rate.

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
INTRODUCTION Educating residents on laparoscopic operations requires direct teaching and deliberate practice. Attending surgeons are often systematic when performing surgery, which creates a challenge when instructing surgery residents. The aim of this study was to use cognitive task analysis to expand laparoscopic cholecystectomy into microsteps reflecting expert surgeon cognition (perceptions, assessments, decisions, etc.) throughout the operation such that these could be better formalized and conveyed to residents in educational materials or assessments and to attending surgeons as teaching scripts. MATERIALS AND METHODS One surgeon, a surgical resident, and a human factors specialist conducted cognitive task analyses with three expert general surgeons and one hepatobiliary surgeon using semi-structured interviews. These interviews expanded an existing task model of laparoscopic cholecystectomy to specifically add patient safety aspects including injury prevention, risk management, and complication detection for each step. Interview analysis resulted in an expanded task diagram. RESULTS Cognitive task analysis expanded the current laparoscopic cholecystectomy task model from 19 to 97 microsteps. In addition to microsteps, an additional major step was identified, the planning step or step zero. Steps with the greatest number of microsteps included dissection with 15 microsteps and intraoperative cholangiogram with 10 microsteps. DISCUSSION Laparoscopic cholecystectomies are complex operations with multiple microsteps. Identification of these steps can lead to explicit strategies that can improve training of surgeons, with an end towards efficacy and safety. The identification of a planning step prior to beginning the operation is a significant finding that should arguably be included in all future cognitive task analyses regardless of operation or procedure, to emphasize to trainees what senior surgeons have learned through experience. These findings inform the development of interventions for surgical training and evaluation of competency.

Abstract
BACKGROUND Less invasive alternatives than early cholecystectomy (EC) for acute calculous cholecystitis (ACC) treatment have been spreading in recent years. We still lack a reliable tool to select high-risk patients who could benefit from these alternatives. Our study aimed to prospectively validate the Chole-risk score in predicting postoperative complications in patients undergoing EC for ACC compared with other preoperative risk prediction models. METHOD The S.P.Ri.M.A.C.C. study is a World Society of Emergency Surgery prospective multicenter observational study. From 1st September 2021 to 1st September 2022, 1253 consecutive patients admitted in 79 centers were included. The inclusion criteria were a diagnosis of ACC and to be a candidate for EC. A Cochran-Armitage test of the trend was run to determine whether a linear correlation existed between the Chole-risk score and a complicated postoperative course. To assess the accuracy of the analyzed prediction models-POSSUM Physiological Score (PS), modified Frailty Index, Charlson Comorbidity Index, American Society of Anesthesiologist score (ASA), APACHE II score, and ACC severity grade-receiver operating characteristic (ROC) curves were generated. The area under the ROC curve (AUC) was used to compare the diagnostic abilities. RESULTS A 30-day major morbidity of 6.6% and 30-day mortality of 1.1% were found. Chole-risk was validated, but POSSUM PS was the best risk prediction model for a complicated course after EC for ACC (in-hospital mortality: AUC 0.94, p < 0.001; 30-day mortality: AUC 0.94, p < 0.001; in-hospital major morbidity: AUC 0.73, p < 0.001; 30-day major morbidity: AUC 0.70, p < 0.001). POSSUM PS with a cutoff of 25 (defined in our study as a 'Chole-POSSUM' score) was then validated in a separate cohort of patients. It showed a 100% sensitivity and a 100% negative predictive value for mortality and a 96-97% negative predictive value for major complications. CONCLUSIONS The Chole-risk score was externally validated, but the CHOLE-POSSUM stands as a more accurate prediction model. CHOLE-POSSUM is a reliable tool to stratify patients with ACC into a low-risk group that may represent a safe EC candidate, and a high-risk group, where new minimally invasive endoscopic techniques may find the most useful field of action.

Background
Less invasive alternatives than early cholecystectomy (EC) for acute calculous cholecystitis (ACC) treatment have been spreading in recent years. We still lack a reliable tool to select high-risk patients who could benefit from these alternatives. Our study aimed to prospectively validate the Chole-risk score in predicting postoperative complications in patients undergoing EC for ACC compared with other preoperative risk prediction models.

To assess the accuracy of the analyzed prediction models—POSSUM Physiological Score (PS), modified Frailty Index, Charlson Comorbidity Index, American Society of Anesthesiologist score (ASA), APACHE II score, and ACC severity grade—receiver operating characteristic (ROC) curves were generated. The area under the ROC curve (AUC) was used to compare the diagnostic abilities.
Results
A 30-day major morbidity of 6.6% and 30-day mortality of 1.1% were found. Chole-risk was validated, but POSSUM PS was the best risk prediction model for a complicated course after EC for ACC (in-hospital mortality: AUC 0.94, p < 0.001; 30-day mortality: AUC 0.94, p < 0.001; in-hospital major morbidity: AUC 0.73, p < 0.001; 30-day major morbidity: AUC 0.70, p < 0.001).

Abstract
BACKGROUND The assessment of laparoscopic cholecystectomy (LC) skills using operating times has not been well reported. We examined the total and partial operating times for LC procedures performed by surgical trainees to determine the required number of surgeries until the surgical time stabilizes. METHODS We reviewed the video records of 514 consecutive LCs using the three-port method, performed by 16 surgical trainees. The total and partial surgical times were calculated and correlated to the surgeons' experience. RESULTS The median total surgical time for a trainee's first LC was 112 (range 71-226) minutes. It reduced rapidly after the first 20 LCs and plateaued to its minimum after approximately 60 cases. A statistically significant time decrease was observed between the first 10 (median, range 112, 46-252 min) and the next 50-59 cases (64, 34-198 min), but not between the 50-59 and the subsequent 100-109 cases (71, 33-127 min). The total times taken by trainees who had performed > 50 operations were not significantly different from those taken by instructors during the study period. Surgery for 125 patients with acute cholecystitis took a significantly longer time (median 99 vs. 74 min with non-acute cholecystitis); however, the abovementioned time reduction findings showed similar results regardless of the patient's acute inflammation status. The partial operating times around the cervical/cystic duct and gallbladder bed reduced uniformly between the first 10 and the following 50-59 cases. Although time variations in total and cervical/cystic duct operating times were not correlated to the surgical experience, time fluctuation of gallbladder bed procedures reduced after 60 cases. CONCLUSION The time required to perform an LC was inversely correlated with the experience of surgical trainees and halved after the first 60 cases. The surgical experience required for LC time stabilization is approximately 60 cases.

Abstract
INTRODUCTION Vasculobiliary injury (VBI) is a rare but critical complication of laparoscopic cholecystectomy (Lap-C). Dividing first the gallbladder body and then the gallbladder neck from the gallbladder bed (the "body-first approach") may decrease the possibility of VBI. METHODS The surgical outcome of 62 patients who underwent Lap-C with a body-first approach were evaluated. In this procedure, after serosal resection of the gallbladder, the gallbladder body is divided from the cystic plate; then the gallbladder neck and cystic duct are isolated. No connective tissue of the hepatic hilum is touched. RESULTS A total of five patients had anatomical anomalies of the biliary tract that raised concerns of cholecystectomy. Furthermore, seven patients underwent subtotal cholecystectomy. No patients required conversion to open surgery, and none developed VBI or postoperative complications of Clavien-Dindo grade 3a or worse. CONCLUSION The body-first approach may minimize the risk of VBI during Lap-C.

Abstract
BACKGROUND Tokyo Guidelines 2018, clinical practice guidelines for acute cholangitis and cholecystitis, recommend bailout procedures to prevent bile duct injury (BDI) during laparoscopic cholecystectomy (LC) for difficult gallbladder. We first insert an additional port (AP) for difficult gallbladder that may require bailout procedures. Because the usefulness of an AP during LC is unclear, we therefore examined the efficacy of the AP during LC in this study. METHODS Data were collected from 115 patients who underwent LC for acute cholecystitis in our department. The indications for AP were excessive bleeding, scarring, and poor visual field around Calot's triangle. AP was inserted into the right middle abdomen so as not to interfere with other trocars and was used by the assistant. Surgical outcomes were evaluated based on AP use during LC. RESULTS AP was inserted in 19 patients during LC (AP group). The indications for AP were excessive bleeding in nine patients, scarring around Calot's triangle in seven patients, and poor visual field around Calot's triangle in three patients. Open conversion was performed in two patients in the non-AP group. BDI occurred in one patient in the non-AP group. In patients with Difficulty Score 3, operation time was significantly shorter (P = .038) and Critical View of Safety (CVS) score was significantly higher in the AP group (P = .046). CONCLUSION AP is useful in patients with excessive bleeding to shorten operation time and increase the CVS score. AP may be one useful option for difficult gallbladder.

Abstract
We herein report a case in which a cystic artery arising from the middle hepatic artery (MHA) was encountered during cholecystectomy. A 42-year-old man visited the outpatient department complaining of chronic epigastric pain and a laparoscopic cholecystectomy was decided upon. During the preoperative evaluation, an interesting finding was observed on computed tomography. The patient had a cystic artery arising from the MHA. An MHA derived from the hilum of the proper hepatic artery runs along the medial border of the gallbladder and enters segment IV. In the operative field, the MHA that entered segment IV was observed. Dissecting downward along the MHA, a cystic artery was observed around the cystic duct. The cystic artery and duct were isolated and each was separately ligated and cut. Rare anatomical variations of the cystic artery, as in this case, can be a pitfall inducing complications during cholecystectomy.

Abstract
BACKGROUND Laparoscopic cholecystectomies continue to pose trouble for surgeons in the face of severe inflammation. In the advent of inability to perform an adequate dissection, a "bailout cholecystectomy" is advocated. Conversion to open or subtotal cholecystectomy is among the standard bailout procedures in such instances. METHODS We performed a retrospective single institution review from January 2016 to August 2019. All patients who underwent a cholecystectomy were included, while those with a concurrent operation, malignancy, planned as an open cholecystectomy, or performed by a low volume surgeon were excluded. Patient characteristics, operative reports, and outcomes were collected, as were surgeon characteristics such as years of experience, case volume, and bailout rate. Univariable and multivariable analysis were performed. RESULTS 2458 (92.6%) underwent laparoscopic total cholecystectomy (LTC) and 196 (7.4%) underwent a bailout cholecystectomy (BOC). BOC patients tended to be older (p < 0.001), male (p < 0.001), have a longer duration of symptoms (p < 0.001), and higher ASA class (p < 0.001). They also had more signs of biliary inflammation, as evidenced by increased leukocytosis (p < 0.001), tachycardia (p < 0.001), bilirubinemia (p = 0.003), common bile duct dilation (p < 0.001), and gallbladder wall thickening (p < 0.001). The BOC cohort also had increased rates of complications, including bile leak (16%, p < 0.001), retained stone (5.1%, p = 0.005), operative time (114 min vs 79 min, p < 0.001), and secondary interventions (22.7%, p < 0.001). Male gender (aOR = 2.8, p < 0.001), preoperative diagnosis of acute cholecystitis (aOR = 2.2, p = 0.032), right upper quadrant tenderness (aOR = 3.0, p = 0.008), Asian race (aOR = 2.7, p = 0.014), and intraoperative adhesions (aOR = 13.0, p < 0.001) were found to carry independent risk for BOC. Surgeon bailout rate ≥ 7% was also found to be an independent risk factor for conversion to BOC. CONCLUSIONS Male gender, signs of biliary inflammation (tachycardia, leukocytosis, dilated CBD, and diagnosis of acute cholecystitis), as well as surgeon bailout rate of 7% were independent risk factors for BOC.

Abstract
BACKGROUND: Laparoscopic cholecystectomy considers a golden surgery for gallbladder removal nowadays, and it carries some complications like biliary injuries, which can manage successfully by endoscopic retrograde cholangiopancreatography.
AIM: To estimate the role of endoscopic management of bile duct injury (BDI) following laparoscopic cholecystectomy.
PATIENT AND METHODS: A prospective study conducted at Al-Sader Medical City, Najaf City, Iraq, during the period between September 2018 and December 2020, included 44 patients complicated by the biliary injury resulting in a persistent biliary leak and/or jaundice after laparoscopic cholecystectomy and evaluated by endoscopic retrograde cholangiopancreatography (ERCP).
RESULTS: Findings revealed that 25% of cases had complete BDI, only one managed by plastic stent placement, the other 10 referred for open surgical constructions, 61% had partial injury associated with the biliary leak, all managed by sphincterotomy and plastic stent placement through ERCP, almost 7% had a partial clipping of bile duct all managed with sphincterotomy, balloon dilatation/stone extraction, and plastic stent placement, 5% had slipped clips of cystic duct stump, are managed with sphincterotomy and plastic stent placement. Moreover, only one patient, 2%, had distal common bile duct stone with bile leak, managed by sphincterotomy and stone extraction.
CONCLUSIONS: Laparoscopic cholecystectomy, a gold standard therapeutic option for symptomatic cholecystolithiasis, is associated with an increased risk of biliary injury due to many factors. ERCP is a safe means of diagnosing the cause of bile leakage after laparoscopic cholecystectomy. It also offers definitive treatment in most cases by endoscopic sphincterotomy and plastic stent placement.

[PMID: 33882292 DOI: 10.1016/j.athoracsur.2021.04.009] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 03/01/2021] [Accepted: 04/01/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Expedited discharge (within 24 hours) following lung resection has received scrutiny due to concerns for higher readmissions and paradoxically increased costs. The present study examined the impact of expedited discharge on hospitalization costs and unplanned readmissions using a nationally-representative sample. In addition, we sought to determine inter-hospital practice variation. METHODS Adults undergoing elective lobar or sublobar resection were identified using the 2016-2018 Nationwide Readmissions Database, while those with postoperative duration of hospitalization >5 days or experienced any perioperative complication, were excluded. Patients were classified as Expedited if postoperative hospitalization was 0 or 1 day and otherwise as Routine. Inverse probability of treatment weighing was utilized to adjust for intergroup differences. Hospitals were ranked according to risk-adjusted early discharge rates. Multivariable regression models were developed to assess the association of expedited discharge on nonelective 30-day readmissions as well as associated mortality and costs. RESULTS Of an estimated 84,152 patients, 13,834 (16.4%) comprised the Expedited group. Compared to Routine, Expedited were younger, less likely to have chronic obstructive pulmonary disease and undergo open procedures. Following adjustment, early discharge was associated with lower incremental costs (β coefficient: -$3.6K, 95%CI: -4.4 - -2.8) as well as similar readmissions (odds ratio: 0.89, 95%CI: 0.70 - 1.13) and related-mortality. Nearly half (48.1%) of all hospitals performed zero early discharges. CONCLUSIONS Expedited discharge following lung resection is a feasible management strategy and is associated with decreased costs and similar readmission risk compared to the norm. Select individuals should be strongly considered for expedited discharge following lung resection.

Abstract
Backgrounds/Aims In the absence of national registry of laparoscopic cholecystectomy (LC) or its complications, it is impossible to determine incidence of bile duct injury (BDI) in India. We conducted an e-survey among practicing surgeons to determine prevalence and management patterns of BDI in India. Our hypothesis was that majority of surgeons would have experienced a BDI during LC despite large experience and that most surgeons who have a BDI tend to manage it themselves. Methods An 18-question e-survey of practicing laparoscopic surgeons in India was done. Results 278/727 (38%) surgeons responded. 240/278 (86%) respondents admitted to a BDI during LC and 179/230 (78%) affirmed to more than one BDI. A total of 728 BDIs were reported. 36/230 (15%) respondents experienced their first BDI even after >10 years of practice and 40% had their first BDI even after having performed >100 LCs. 161/201 (80%) of the respondents decided to manage the BDI themselves, including 56/99 (57%) non-biliary surgeons and 44/82 (54%) surgeons working in non-biliary center. 37/201 (18%) respondents admitted to having a mortality arising out of a BDI; the mortality rate of BDI was 37/728 (5%) in this survey. Only 13/201 (6%) respondents have experienced a medico-legal case related to a BDI during LC. Conclusions Prevalence of BDI is high in India and occurs despite adequate experience and volume. Even inexperienced non-biliary surgeons working in non-biliary centers attempt to repair the BDI themselves. BDI is associated with significant mortality but litigation rates are fortunately low in India.

Abstract
INTRODUCTION Laparoscopic cholecystectomy (LC) is considered difficult in patients with an impacted gallstone (IG). We examined the efficacy of releasing an IG after percutaneous transhepatic gallbladder drainage (PTGBD) for acute cholecystitis (AC) and the usefulness of the Difficulty Score (DS) proposed in the Tokyo Guidelines 2018. METHODS Data were collected from 28 patients who underwent LC after PTGBD for AC caused by an IG in our department. The IG was released by flushing the gallbladder with saline or performing cholecystography. Release of the IG was evaluated based on cholecystography or drainage findings. Surgical outcomes were evaluated by comparing whether the IG could be released. RESULTS Nine patients had an IG (IG group) and 19 had a released IG at the time of surgery. Operation time was significantly longer (P = .008), Critical View of Safety score was significantly lower (P = .019), and DS was significantly higher (P < .001) in the IG group. In multivariate analysis, DS was the only independent factor for operation time (odds ratio = 8.943, 95% confidence interval 1.179-167.032; P = .033). CONCLUSION Releasing an IG may reduce surgical difficulty and maintain surgical safety. DS can be useful in predicting surgical outcomes.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17207571. [PMID: 33080991 PMCID: PMC7588875 DOI: 10.3390/ijerph17207571] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/27/2020] [Revised: 10/01/2020] [Accepted: 10/15/2020] [Indexed: 12/24/2022]
Abstract
Laparoscopic cholecystectomy is a standard treatment for cholelithiasis. In situations where laparoscopic cholecystectomy is dangerous, a surgeon may be forced to change from laparoscopy to an open procedure. Data from the literature shows that 2 to 15% of laparoscopic cholecystectomies are converted to open surgery during surgery for various reasons. The aim of this study was to identify the risk factors for the conversion of laparoscopic cholecystectomy to open surgery. A retrospective analysis of medical records and operation protocols was performed. The study group consisted of 263 patients who were converted into open surgery during laparoscopic surgery, and 264 randomly selected patients in the control group. Conversion risk factors were assessed using logistic regression analysis that modeled the probability of a certain event as a function of independent factors. Statistically significant factors in the regression model with all explanatory variables were age, emergency treatment, acute cholecystitis, peritoneal adhesions, chronic cholecystitis, and inflammatory infiltration. The use of predictive risk assessments or nomograms can be the most helpful tool for risk stratification in a clinical scenario. With such predictive tools, clinicians can optimize care based on the known risk factors for the conversion, and patients can be better informed about the risks of their surgery.

Predicting the difficult laparoscopic cholecystectomy: development and validation of a pre-operative risk score using an objective operative difficulty grading system. Surg Endosc 2020; 34:4549-4561. [PMID: 31732855 DOI: 10.1007/s00464-019-07244-5] [Citation(s) in RCA: 41] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Accepted: 10/28/2019] [Indexed: 01/25/2023]
Abstract
BACKGROUND The prediction of a difficult cholecystectomy has traditionally been based on certain pre-operative clinical and imaging factors. Most of the previous literature reported small patient cohorts and have not used an objective measure of operative difficulty. The aim of this study was to develop a pre-operative score to predict difficult cholecystectomy, as defined by a validated intra-operative difficulty grading scale. METHOD Two cohorts from prospectively maintained databases of patients who underwent laparoscopic cholecystectomy were analysed: the CholeS Study (8755 patients) and a single surgeon series (4089 patients). Factors potentially predictive of difficulty were correlated to the Nassar intra-operative difficulty scale. A multivariable binary logistic regression analysis was then used to identify factors that were independently associated with difficult laparoscopic cholecystectomy, defined as operative difficulty grades 3 to 5. The resulting model was then converted to a risk score, and validated on both internal and external datasets. RESULT Increasing age and ASA classification, male gender, diagnosis of CBD stone or cholecystitis, thick-walled gallbladders, CBD dilation, use of pre-operative ERCP and non-elective operations were found to be significant independent predictors of difficult cases. A risk score based on these factors returned an area under the ROC curve of 0.789 (95% CI 0.773-0.806, p < 0.001) on external validation, with 11.0% versus 80.0% of patients classified as low versus high risk having difficult surgeries. CONCLUSION We have developed and validated a pre-operative scoring system that uses easily available pre-operative variables to predict difficult laparoscopic cholecystectomies. This scoring system should assist in patient selection for day case surgery, optimising pre-operative surgical planning (e.g. allocation of the procedure to a suitably trained surgeon) and counselling patients during the consent process. The score could also be used to risk adjust outcomes in future research.

Abstract
BACKGROUND Cholecystitis before cholecystectomy may increase risk of cancers in the hepato-pancreato-biliary area. METHODS A population-based cohort study of all patients undergoing cholecystectomy in Denmark during 1996-2015, using nationwide healthcare registries. We retrieved information on cholecystitis within two years before the date of surgery and information on pancreatic cancer, hepatocellular carcinoma (HCC), and biliary tract cancer. We examined cancer risk using a Cox model to calculate the hazard ratios (HRs). We also computed cumulative incidence functions with 95% CIs, comparing patients with and without cholecystitis before cholecystectomy. RESULTS We included 132,794 patients, of which 73.0% were women. In the first five years of follow-up, we observed an increased risk of biliary tract cancer, but not pancreatic cancer or HCC, in patients with prior cholecystitis. After more than five years of follow-up, patients with prior cholecystitis had an increased risk of pancreatic cancer (adjusted HR: 1.26; 95% CI: 0.98-1.63) and possibly biliary tract cancer (adjusted HR: 1.33; 95% CI: 0.64-2.77). Long-term risk of HCC was decreased in patients with prior cholecystitis. For all cancers, the 20-year absolute risks were less than 1%. CONCLUSION In patients undergoing cholecystectomy, prior cholecystitis was associated with increased risk of pancreatic and possibly biliary tract cancer.

Abstract
BACKGROUND Patients with typical biliary pain, no gallstones on ultrasound and low gallbladder ejection fraction (GBEF) on cholescintigraphy (gallbladder dyskinesia) may be considered for a laparoscopic cholecystectomy. However, some studies have suggested that symptoms alone are an adequate indication for laparoscopic cholecystectomy. The aim was to determine the role of cholescintigraphy in predicting outcomes of cholecystectomy in patients with typical and atypical biliary symptoms and normal biliary ultrasound. METHODS Meta-analysis using Preferred Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines of published literature using several electronic databases. RESULTS Twenty-four articles were selected with a total of 1710 patients. The majority (n = 1633, 94.4%) of patients had typical biliary symptoms. A total of 1047 patients with typical symptoms and a reduced GBEF had a cholecystectomy with 852 (81.4%) having complete resolution of symptoms. A total of 148 with typical symptoms and normal GBEF had a cholecystectomy with 103 (69.5%) having complete resolution, which was significantly less than those with a reduced GBEF (odds ratio 1.65, confidence interval 1.08-2.05, P = 0.01). Forty-five patients with atypical symptoms and a reduced GBEF had a cholecystectomy with 31 (68.9%) having complete resolution of symptoms, which is significantly lower than those with typical symptoms (odds ratio 1.97, confidence interval 0.95-3.90, P = 0.05). CONCLUSION Cholescintigraphy improved the predication of outcome of cholecystectomy in biliary dyskinesia by 10%. However, the presence of typical symptoms does predict an effective response in 70% of patients. Atypical symptoms predict a poorer response.

Abstract
BACKGROUND The occurrence of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is an important medical issue. Expert surgeons prevent intraoperative BDI by identifying four landmarks. The present study aimed to develop a system that outlines these landmarks on endoscopic images in real time. METHODS An intraoperative landmark indication system was constructed using YOLOv3, which is an algorithm for object detection based on deep learning. The training datasets comprised approximately 2000 endoscopic images of the region of Calot's triangle in the gallbladder neck obtained from 76 videos of LC. The YOLOv3 learning model with the training datasets was applied to 23 videos of LC that were not used in training, to evaluate the estimation accuracy of the system to identify four landmarks: the cystic duct, common bile duct, lower edge of the left medial liver segment, and Rouviere's sulcus. Additionally, we constructed a prototype and used it in a verification experiment in an operation for a patient with cholelithiasis. RESULTS The YOLOv3 learning model was quantitatively and subjectively evaluated in this study. The average precision values for each landmark were as follows: common bile duct: 0.320, cystic duct: 0.074, lower edge of the left medial liver segment: 0.314, and Rouviere's sulcus: 0.101. The two expert surgeons involved in the annotation confirmed consensus regarding valid indications for each landmark in 22 of the 23 LC videos. In the verification experiment, the use of the intraoperative landmark indication system made the surgical team more aware of the landmarks. CONCLUSIONS Intraoperative landmark indication successfully identified four landmarks during LC, which may help to reduce the incidence of BDI, and thus, increase the safety of LC. The novel system proposed in the present study may prevent BDI during LC in clinical practice.

Abstract
OBJECTIVE Although minimally invasive techniques have led to shorter hospitalizations, discharge on postoperative day 1 is still uncommon. We hypothesized that day 1 discharge could be performed safely and that there might be significant variation in day 1 discharge rates between hospitals. METHODS We identified patients with lung cancer who underwent lobectomy and segmentectomy in the Society of Thoracic Surgeons Database from 2012 to 2017. The 10% longest hospital stay outliers were excluded. A multivariable regression model was created to assess for factors associated with day 1 discharge and readmission. RESULTS A total of 46,325 patients were examined, and 1821 patients (3.9%) were discharged on day 1. This rate increased from 3.4% to 5.3% over the course of the study (P < .0001). In multivariable analysis, factors associated with day 1 discharge included age, Zubrod score, body mass index greater than 25, forced expiration value at 1 second, middle or upper lobectomy, minimally invasive technique, and procedure time. Outpatient 30-day mortality was similar (0.3% vs 0.4%, P = .472). Patients discharged on day 1 were not at increased risk of readmission. Readmission after day 1 discharge was associated with male sex, coronary artery disease, chronic obstructive pulmonary disease, and longer procedure time. There was substantial variation in day 1 discharge rate between institutions, with 11 centers (4.0%) discharging more than 20% of their patients on day 1, whereas 102 centers (36.7%) had no day 1 discharges. CONCLUSIONS Day 1 discharge after anatomic lung resection is uncommon but is becoming more common. Carefully selected patients may be discharged on day 1 without an increased risk of readmission or death.

Abstract
INTRODUCTION iatrogenic bile duct injury (IBDI) is a complication with a high morbidity after cholecystectomy. In recent years, endoscopy has acquired a fundamental role in the management of this pathology. METHODS a retrospective study of IBDI after open cholecystectomy (OC) or laparoscopic cholecystectomy (LC) of patients treated in our center between 1993 and 2017 was performed. Clinical characteristics, type of injury according to the Strasberg-Bismuth classification, diagnosis, repair techniques and follow-up were analyzed. RESULTS 46 patients were studied and IBDI incidence was 0.48%, 0.61% for LC and 0.24% for OC. A diagnosis was made intraoperatively in 12 cases (26%) and by endoscopic retrograde cholangiopancreatography (ERCP) in 10 (21.7%) cases. The most common IBDI patient characteristics were acute cholecystitis (20/46, 43.5%), previous admission due to biliary pathology (16/46, 43.2%) and ERCP prior to cholecystectomy (7/46, 18.9%). The most frequent types of IBDI were D (17/46, 36.9%) and A (15/46, 32.6%). The most commonly used treatment was primary suture (13/46, 28.3%) followed by ERCP (11/46, 23.9%) with sphincterotomy and/or stents. In addition, ERCP was performed during the immediate postoperative period in 6 (13%) patients with a surgical IBDI repair in order to resolve immediate complications. CONCLUSION ERCP is useful in the management of IBDI that is not diagnosed intraoperatively. This procedure facilitates the localization of the injured area of the bile duct, therapeutic maneuvers and successful outcomes in postoperative complications.

Routine near infra-red indocyanine green fluorescent cholangiography versus intraoperative cholangiography during laparoscopic cholecystectomy: a case-matched comparison. Surg Endosc 2019; 34:1959-1967. [PMID: 31309307 DOI: 10.1007/s00464-019-06970-0] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2019] [Accepted: 07/01/2019] [Indexed: 12/18/2022]
Abstract
BACKGROUND The aim is to evaluate safety and efficacy of near infra-red (NIR) indocyanine green (ICG) fluorescence structural imaging during laparoscopic cholecystectomy (LC) (Group A) and to compare perioperative data, including operative time, with a series of patients who underwent LC with routine traditional intraoperative cholangiography (IOC) (Group B). METHODS Forty-four patients with acute or chronic cholecystitis underwent NIR-ICG fluorescent cholangiography during LC. ICG was administered intravenously at different time intervals or by direct gallbladder injection during surgery. Fluorescence intensity and anatomy identification were scored according to a visual analogue scale between 1 (least accurate) and 5 (most accurate). Group B patients (n = 44) were chosen from a prospectively maintained database of patients who underwent LC with routine IOC, matched for age, sex, body mass index, and diagnosis with group A patients. RESULTS No adverse reactions were recorded. In group A, mean time between intravenous administration of ICG and surgery was 10.7 ± 8.2 (range 2-52) h. Administered doses ranged from 3.5 to 13.5 mg. Fluorescence was present in all cases, scoring ≥ 3 in 41 patients. Mean operative time was 86.9 ± 36.9 (30-180) min in group A and 117.9 ± 43.4 (40-220) min in group B (p = 0.0006). No conversion to open surgery nor bile duct injuries were observed in either group. CONCLUSIONS LC with NIR-ICG fluorescent cholangiography is safe and effective for early recognition of anatomical landmarks, reducing operative time as compared to LC with IOC, even when residents were the main operator. NIR-ICG fluorescent cholangiography was effective in patients with acute cholecystitis and in the obese. Data collection into large registries on the results of NIR-ICG fluorescent cholangiography during LC should be encouraged to establish whether this technique might set a new safety standard for LC.

Abstract
Backgrounds/Aims Traditional outcome measures (e.g., length of hospital stay, morbidity, and mortality) are used to determine the quality of care, but these may not be most important to patients. It is unclear which outcomes matter to patients undergoing elective laparoscopic cholecystectomy (ELC). We aim to identify patient-reported outcome measures (PROM) which patients undergoing ELC valued most. Methods A 45-item questionnaire with Four-point Likert-type questions developed from prior literature review, prospectively administered to patients treated with ELC at a tertiary institution in Singapore. Results Seventy-five patients participated. Most essential factors were technical skill and experience level of a surgeon, long-term quality of life (QoL), patient involvement in decision-making, communication skill of a surgeon, cleanliness of the ward environment, and standards of nursing care. Least important factors were hospitalization leave duration, length of hospital stay, a family's opinion of the hospital, and scar cosmesis. Employed patients were more likely to find hospitalization leave duration (p<0.001) and procedure duration (p=0.042) important. Younger patients (p=0.048) and female gender (p=0.003) were more likely to perceive scar cosmesis as important. Conclusions Patients undergoing ELC value long-term QoL, surgeon technical skill and experience level, patient involvement in decision-making, surgeon communication skill, cleanliness of the ward environment, and nursing care standards. Day-case surgery, medical leave, family opinion of hospital, and scar cosmesis were least important. Understanding what patients value will help guide patient-centric healthcare delivery.

Abstract
BACKGROUND Symptomatic gall stones are treated safely and efficiently with laparoscopic cholecystectomy. Conversion to open cholecystectomy may be associated with adverse outcomes. Accurate prediction of conversion should decrease the incidence of conversion and improve patient care. METHODS The recent literature on conversion at laparoscopic cholecystectomy is reviewed to identify robust prediction models that are both internally and externally validated. RESULTS Two prediction models are identified which meet these criteria. CONCLUSIONS The Cairns Prediction Model using nomograms, is an easily applied tool predicting conversion, which is presently in use. Routine use of this tool should decrease conversion, and improve the process of patient consent.

Abstract
Background The average hospitalization after lung resection is 6 days, but some patients are discharged early in the post-operative period. The patient factors associated with early discharge (ED) and the safety of this approach are unknown. We hypothesized that specific patient populations are associated with ED, and that complications in this practice are low. Methods A prospective database of lung resections performed at an academic medical center between Jan 1, 2007 and Jan 1, 2017 was queried. Demographic and outcome variables were assessed using standard techniques. ED was defined as the length of stay (LOS) for the quintile with the lowest LOS for patients with anatomic resection (AR) or patients with wedge resection (WR). We then compared clinical factors between patients with ED to those patients discharged by day 7, to determine factors associated with ED (relative to "average" discharge). Results During the study period, there were 922 AR and 1,150 WR performed. A total of 448 (39.0%) patients had WRED and 211 patients (22.9%) had ARED. The rate of WRED varied by surgeon, but ARED did not. ARED and WRED patients was associated with several factors, including younger age, better lung function, and were less likely to have elevated American Society of Anesthesiologist (ASA) class. Multivariable analysis suggested that patient factors and primary surgeon influence ED. WRED was associated with 30-day mortality of 0.22% vs. 1.14% for longer LOS (P=0.08). After AR, there were no post-operative deaths within 30 days among 211 patients discharged on postoperative day 1 or 2 [(vs. 2/541, 0.4%, P=0.376) with longer LOS, P=0.048]. Conclusions ED after lung resection is multifactorial but is safe among selected patients. Age, lung function, procedure duration, and surgeon all influence ED. Complications after ED were rare. Individual surgeon comfort with ED likely impacts LOS, and education or enhanced recovery protocols may help overcome this barrier. Standardized pathways would likely help identify low-risk patients for expeditious discharge.

Abstract
The study covered a cohort of 236 patients with transection of hepatic duct. It aimed to assess the long-term outcome of the reconstruction and a patient's quality of life.The literature contains many controversies over timing of biliary reconstruction and who ought to repair the injury but just few reports on the long-term outcomes and patient's quality of life.The bile duct system was reconstructed by hepaticojejunostomy in 236 patients. Of these, 139 patients were initially repaired at a public hospital and referred because of stricture (Group A, N = 59) or of an anastomosis dehiscence (Group B, N = 80); 97 were unrepaired and referred because of a surgical clip occluding the duct (Group C, N = 39) or bile leakage from an open duct (Group D, N = 58). All patients were surveyed in 2015 for quality of life using WHOQOL-BREF.The mean time of follow-up was 150 months. The time without symptoms amounted to >5 years in 78.6% of patients. The mean time before anastomosis renewal ranged from 8.9 to 4.7 years (P < .04). Multivariate analysis showed infection, failure of reconstruction in public hospital, and female sex as factors responsible for poor long-term outcome.Patients in Group C had better quality of life than the others (P < .001) with respect to physical health (median 67.85) and psychological condition (median 79.16). The overall mortality was 15.2%.The long-term result of reconstruction depends on the cause of referral which, in turn, arises from subsequent intervention taken in local hospitals.

Abstract
PURPOSE Choledochocystolithiasis and its associated complications such as cholangitis and pancreatitis are managed by endoscopic retrograde cholangiography (ERC), with endoscopic stone extraction followed by laparoscopic cholecystectomy (LC). However, affected patients present with complex conditions linked to operative difficulties in performing LC. The aim of this study was to elucidate the predictive factors for a prolonged LC procedure following ERC for treating patients with choledochocystolithiasis. MATERIALS AND METHODS The medical records of 109 patients who underwent LC after ERC for choledochocystolithiasis from September 2012 to August 2014 were evaluated retrospectively. The cases were divided into long and short operative duration groups using a cutoff operative time of 90 minutes. We used univariate and multivariate analyses to investigate predictive factors associated with long operative duration according to clinical variables, ERC-related factors, and peak serum levels of laboratory test values between the initial presentation and LC (intervening period). RESULTS Seventeen patients needed >90 min to complete LC. The presence of acute cholecystitis, placement of percutaneous transhepatic gallbladder drainage, higher peak serum white blood cell count and levels of C-reactive protein (CRP), and lower peak serum levels of lipase during the intervening period were associated with prolonged operative duration. Multivariate analysis showed that the independent predictive factors for long operative duration were the presence of acute cholecystitis (hazard ratio, 5.418; P=0.016) and higher peak levels of CRP (hazard ratio, 1.077; P=0.022). CONCLUSION When patients with choledochocystolithiasis are scheduled for LC after ERC, the presence of acute cholecystitis and high CRP levels during the intervening period could predict a protracted operation.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC), one of the most commonly performed surgical procedures, remains associated with significant major morbidity including bile leak and bile duct injury (BDI). The effect of changes in practice over time, and of interventions to improve patient safety, on morbidity rates is not well understood. The aim of this review was to describe current incidence rates and trends for BDI and other complications during and after LC, and to identify risk factors and preventative measures associated with morbidity and BDI. METHODS PubMed, MEDLINE, and Web of Science database searches and data extraction were conducted for studies which reported individual complications and complication rates following laparoscopic cholecystectomy in a representative population. Outcomes data were pooled. Meta-regression analysis was performed to assess factors associated with conversion, morbidity, and BDI rates. RESULTS One hundred and fifty-one studies reporting outcomes for 505,292 patients were included in the final quantitative synthesis. Overall morbidity, BDI, and mortality rates were 1.6-5.3%, 0.32-0.52%, and 0.08-0.14%, respectively. Reported BDI rates reduced over time (1994-1999: 0.69(0.52-0.84)% versus 2010-2015 0.22(0.02-0.40)%, p = 0.011). Meta-regression analysis suggested higher conversion rates in developed versus developing countries (4.7 vs. 3.4%), though a greater degree of reporting bias was present in these studies, with no other significant associations identified. CONCLUSIONS Overall, trends suggest a reduction in BDI over time with unchanged morbidity and mortality rates. However, data and reporting are heterogenous. Establishment of international outcomes registries should be considered.

Abstract
Laparoscopic cholecystectomy (LC) is considered the gold standard for treatment of symptomatic gallbladder stones and has replaced the traditional open cholecystectomy (OC). The aim of this study is to evaluate the proper indications of the primary OC and conversion from LC and their predictive factors. This study includes all patients who underwent cholecystectomy between January 2011 and June 2016, whether open from the start (group A), conversion from laparoscopic approach (group B), or laparoscopic cholecystectomy (group C). There were 3269 patients underwent cholecystectomy. LC was completed in 3117 (95.4%) patients. The overall conversion rate was 83 (2.5%). The main two causes of conversion were adhesion in 35 (42.2%) patients and unclear anatomy in 29 (34.9%) patients. Primary OC was indicated in 69 (2.1%) patients due to previous history of upper abdominal operations in 16 (23.2%) patients and anesthetic problem in 21 (30.4%) patients. Age >60 years, male sex, diabetic patients, history of endoscopic retrograde cholangiopancreatography, dilated common bile duct, gallbladder status, adhesion, and previous upper abdominal operation were demonstrated to be independent risk factors for OC. Open cholecystectomy still has a place in the era of laparoscopy. Conversion should not be a complication, but it represents a valuable choice to avoid an additional risk. Safe OC required training because of the causes of conversion, usually unsafe anatomy, occurrence of complications, or anesthetic problems, in order to prevent disastrous complications.

Abstract
Bile duct injury (BDI) during laparoscopic cholecystectomy remains a serious iatrogenic surgical complication. BDI most often occurs as a result of misidentification of the anatomy; however, clinical evidence on its precise mechanism and surgeons' perceptions is scarce. Surgeons from Japan, Korea, Taiwan, and the USA, etc. (n = 614) participated in a questionnaire regarding their BDI experience and near-misses; and perceptions on landmarks, intraoperative findings, and surgical techniques. Respondents voted for a Delphi process and graded each item on a five-point scale. The consensus was built when ≥80% of overall responses were 4 or 5. Response rates for the first- and second-round Delphi were 60.6% and 74.9%, respectively. Misidentification of local anatomy accounted for 76.2% of BDI. Final consensus was reached on: (1) Effective retraction of the gallbladder, (2) Always obtaining critical view of safety, and (3) Avoiding excessive use of electrocautery/clipping as vital procedures; and (4) Calot's triangle area and (5) Critical view of safety as important landmarks. For (6) Impacted gallstone and (7) Severe fibrosis/scarring in Calot's triangle, bail-out procedures may be indicated. A consensus was reached among expert surgeons on relevant landmarks and intraoperative findings and appropriate surgical techniques to avoid BDI.

Abstract
Laparoscopic cholecystectomy (LC) is one of the first laparoscopic procedures performed by surgical trainees. This study aims to determine preoperative and/or intraoperative predictors of difficult LC and to compare complications of LC performed by trainees with that performed by trained surgeons. A cohort of 180 consecutive patients with cholelithiasis who underwent LC was analyzed. We used univariate and binary logistic regression analyses to predict factors associated with difficult LC. We compared the rate of complications of LCs performed by trainees and that performed by trained surgeons using Pearson's chi-square test. Patients with impacted stone in the neck of the gallbladder (GB) (OR, 5.0; 95% CI, 1.59-15.77), with adhesions in the Triangle of Calot (OR, 2.9; 95% CI, 1.27-6.83), or with GB rupture (OR, 3.4; 95% CI, 1.02-11.41) were more likely to experience difficult LC. There was no difference between trainees and trained surgeons in the rate of cystic artery injury (p = .144) or GB rupture (p = .097). However, operative time of LCs performed by trained surgeons was significantly shorter (median, 45 min; IQR, 30-70 min) compared with the surgical trainees' operative time (60 min; IQR, 50-90 min). Surgical trainees can perform difficult LC safely under supervision with no increase in complications albeit with mild increase in operative time.

Abstract
Background: Laparoscopic cholecystectomy (LC) has been a standard operation and replaced the open cholecystectomy (OC) rapidly because the technique resulted in less pain, smaller incision, and faster recovery. This study was to evaluate the value of blunt dissection in preventing bile duct injury (BDI) in laparoscopic cholecystectomy (LC). Methods: From 2003 to 2015, LC was performed on 21,497 patients, 7470 males and 14,027 females, age 50.3 years (14–84 years). The Calot's triangle was bluntly dissected and each duct in Calot's triangle was identified before transecting the cystic duct. Results: Two hundred and thirty-nine patients (1.1%) were converted to open procedures. The postoperative hospital stay was 2.1 (0–158) days, and cases (46%) had hospitalization days of 1 day or less, and 92.8% had hospitalization days of 3 days or less; BDI was occurred in 20 cases (0.09%) including 6 cases of common BDI, 2 cases of common hepatic duct injury, 1 case of right hepatic duct injury, 1 case of accessory right hepatic duct, 1 case of aberrant BDI 1 case of biliary stricture, 1 case of biliary duct perforation, 3 cases of hemobilia, and 4 cases of bile leakage. Conclusion: Exposing Calot's triangle by blunt dissection in laparoscopic cholecystectomy could prevent intraoperative BDI.

Abstract
BACKGROUND Several authors have demonstrated the safety and feasibility of laparoscopy in selected cases of abdominal emergencies. The aim of the study was to analyse the current Italian practice on the use of laparoscopy in abdominal emergencies and to evaluate the impact of the 2012 national guidelines on the daily surgical activity. METHODS Two surveys (42 closed-ended questions) on the use of laparoscopy in acute abdomen were conducted nationwide with an online questionnaire, respectively, before (2010) and after (2014) the national guidelines publication. Data from two surveys were compared using Chi-square or Fisher's exact test, and data were considered significant when p < 0.05. RESULTS Two-hundred and one and 234 surgical units answered to the surveys in 2010 and 2014, respectively. Out of 144,310 and 127,013 overall surgical procedures, 23,407 and 20,102, respectively, were abdominal emergency operations. Respectively 24.74 % (in 2010) versus 30.27 % (in 2014) of these emergency procedures were approached laparoscopically, p = 0.42. The adoption of laparoscopy increased in all the considered clinical scenarios, with statistical significance in acute appendicitis (44 vs. 64.7 %; p = 0.004). The percentage of units approaching Hinchey III acute diverticulitis with laparoscopy in 26-75 % of cases (14.0 vs. 29.7 %; p = 0.009), those with >25 % of surgeons confident with laparoscopic approach to acute diverticulitis (29.9 vs. 54 %; p = 0.0009), the units with >50 % of surgeons confident with laparoscopic approach to acute appendicitis, cholecystitis and perforated duodenal ulcer, all significantly increased in the time frame. The majority of respondents declared that the 2012 national guidelines influenced their clinical practice. CONCLUSIONS The surveys showed an increasing use of laparoscopy for patients with abdominal emergencies. The 2012 national guidelines profoundly influenced the Italian surgical practice in the laparoscopic approach to the acute abdomen.

Abstract
PURPOSE Iatrogenic bile duct injury (BDI) is the most significant associated complication to laparoscopic cholecystectomy (LC). Little is known about the evolution of the pattern of BDI in the era of laparoscopy. The aim of the study is to assess the pattern of post-LC BDIs managed in a tertiary referral centre. METHODS Post-LC BDI referred over two decades were studied. Demographic data, type of BDI (classified using the Strasberg System), clinical symptoms, diagnostic investigations, timing of referral, post-referral management and morbidity were analysed. The pattern of injury, associated vascular injuries rate and their management were compared over two time periods (1992-2004,2005-2014). RESULTS 78 BDIs were referred. During the second time period Strasberg A injuries decreased from 14% to 0 and Strasberg E1increased from 4% to 23%, the rate of associated vascular injury was six time higher (3.6% versus 22.7%), more patients had an attempted repair at the index hospital (16% versus 35%) sand fewer patients could be managed without surgical intervention at the referral hospital (28% versus 4%). CONCLUSION Complexity of referred BDIs and rate of associated vascular injuries have increased over time. These findings led to more patients managed requiring surgical intervention at the referral hospital.

Abstract
BACKGROUND Errors in judgment during laparoscopic cholecystectomy can lead to bile duct injuries and other complications. Despite correlations between outcomes, expertise and advanced cognitive skills, current methods to evaluate these skills remain subjective, rater- and situation-dependent and non-systematic. The purpose of this study was to develop objective metrics using a Web-based platform and to obtain validity evidence for their assessment of decision-making during laparoscopic cholecystectomy. METHODS An interactive online learning platform was developed ( www.thinklikeasurgeon.com ). Trainees and surgeons from six institutions completed a 12-item assessment, developed based on a cognitive task analysis. Five items required subjects to draw their answer on the surgical field, and accuracy scores were calculated based on an algorithm derived from experts' responses ("visual concordance test", VCT). Test-retest reliability, internal consistency, and correlation with self-reported experience, Global Operative Assessment of Laparoscopic Skills (GOALS) score and Objective Performance Rating Scale (OPRS) score were calculated. Questionnaires were administered to evaluate the platform's usability, feasibility and educational value. RESULTS Thirty-nine subjects (17 surgeons, 22 trainees) participated. There was high test-retest reliability (intraclass correlation coefficient = 0.95; n = 10) and internal consistency (Cronbach's α = 0.87). The assessment demonstrated significant differences between novices, intermediates and experts in total score (p < 0.01) and VCT score (p < 0.01). There was high correlation between total case number and total score (ρ = 0.83, p < 0.01) and between total case number and VCT (ρ = 0.82, p < 0.01), and moderate to high correlations between total score and GOALS (ρ = 0.66, p = 0.05), VCT and GOALS (ρ = 0.83, p < 0.01), total score and OPRS (ρ = 0.67, p = 0.04), and VCT and OPRS (ρ = 0.78, p = 0.01). Most subjects agreed or strongly agreed that the platform and assessment was easy to use [n = 29 (78 %)], facilitates learning intra-operative decision-making [n = 28 (81 %)], and should be integrated into surgical training [n = 28 (76 %)]. CONCLUSION This study provides preliminary validity evidence for a novel interactive platform to objectively assess decision-making during laparoscopic cholecystectomy.
