Abstract
INTRODUCTION Artificial intelligence and computer vision are revolutionizing the way we perceive video analysis in minimally invasive surgery. This emerging technology has increasingly been leveraged successfully for video segmentation, documentation, education, and formative assessment. New, sophisticated platforms allow pre-determined segments chosen by surgeons to be automatically presented without the need to review entire videos. This study aimed to validate and demonstrate the accuracy of the first reported AI-based computer vision algorithm that automatically recognizes surgical steps in videos of totally extraperitoneal (TEP) inguinal hernia repair. METHODS Videos of TEP procedures were manually labeled by a team of annotators trained to identify and label surgical workflow according to six major steps. For bilateral hernias, an additional change of focus step was also included. The videos were then used to train a computer vision AI algorithm. Performance accuracy was assessed in comparison to the manual annotations. RESULTS A total of 619 full-length TEP videos were analyzed: 371 were used to train the model, 93 for internal validation, and the remaining 155 as a test set to evaluate algorithm accuracy. The overall accuracy for the complete procedure was 88.8%. Per-step accuracy reached the highest value for the hernia sac reduction step (94.3%) and the lowest for the preperitoneal dissection step (72.2%). CONCLUSIONS These results indicate that the novel AI model was able to provide fully automated video analysis with a high accuracy level. High-accuracy models leveraging AI to enable automation of surgical video analysis allow us to identify and monitor surgical performance, providing mathematical metrics that can be stored, evaluated, and compared. As such, the proposed model is capable of enabling data-driven insights to improve surgical quality and demonstrate best practices in TEP procedures.

Abstract
Background Every year, worldwide, the celebration for patient safety is carried out; since about 2.6 million people are documented who die each year from events that can potentially be avoided during their medical care, it is even estimated that around 15% of hospital costs can be attributed to treatment resulting in patient safety. As an important part of its dissemination in the medical–surgical community, we present the following article in relation to the critical vision of safety in the bile duct, promoted and published initially by Dr Steven Strasberg, which aims to reduce the number of complications during laparoscopic cholecystectomies. Materials and methods A bibliographic search was carried out in PubMed, Medline, Clinical Key, and Index Medicus. From May 2020 to July 2021 in Spanish and English with the following. Conclusions Strasberg's critical view is a proposed strategy to minimize the risk to zero during laparoscopic gallbladder surgery. It consists of obtaining a plane in which the surgeon can visualize the anatomical structures that make up the bile duct, as well as its irrigation and drainage. Being able to clearly observe these structures allows the surgeon to cut freely and safely to avoid bile duct injuries which are not so uncommon during this procedure.

Abstract
The present study was a multicenter, analytical, nonrandomized research on 108 cases of intraoperative vascular and bile duct lesions during laparoscopic cholecystectomies. We selected these cases from 16,559 cholecystectomies performed entirely laparoscopically or debuted laparoscopically and converted to an open approach. The study included two surgical centers labeled as primary, with extensive experience in hepato-biliary reconstructive surgery, and four other centers labeled as secondary that referred cases to the previous two. Our study analyzed several key parameters such as the percentage of iatrogenic lesions recorded, the variability of the main biliary pathway and conformation as well as its relationship to the adjacent critical anatomical landmarks, the anatomical and physiopathological characteristics of pathology requiring surgical intervention, factors related to laparoscopic surgical technique, the surgical technique used to repair the recorded lesions, the duration of survivability and the rate of the occurring complications. Based on the analysis of these parameters, we developed a descriptive algorithm with visual representation relying on several decisional points to guide the surgeons in choosing the optimal treatment method so that patients will benefit from a favorable clinical path.

Abstract
OBJECTIVE The aim of this study was to examine real-life patterns of care and patient outcomes associated with robot-assisted cholecystectomy (RAC) in New York State (NYS). BACKGROUND Although robotic assistance may offer some technological advantages, RACs are associated with higher procedural costs and longer operating times compared to traditional laparoscopic cholecystectomies (LCs). Evidence on long-term patient outcomes after RAC from large population-based datasets remains limited and inconsistent. METHODS Using NYS inpatient and ambulatory surgery data from the Statewide Planning and Research Cooperative System (2009-2017), we conducted bivariate and multivariate analyses to examine patterns of utilization, complications, and secondary procedures following cholecystectomies. RESULTS Among 299,306 minimally invasive cholecystectomies performed in NYS between 2009 and 2017, one thousand one hundred eighteen (0.4%) were robot-assisted. Compared to those undergoing LC, RAC patients were older, travelled further for surgery, and were more likely to have public insurance and preoperative comorbidities. RAC versus LC patients were more significantly likely to have conversions to open procedure (4.9% vs 2.8%), bile duct injuries (1.3% vs 0.4%), and major reconstructive interventions (0.6% vs 0.1%), longer median length of stay (3 vs 1 day), readmissions (7.3% vs 4.4%), and higher 12-month post-index surgery hospital charges (P < 0.01 for all estimates). Other postoperative complications decreased over time for LC but remained unchanged for RAC patients. CONCLUSIONS Patients receiving RAC in NYS experienced higher rates of complications compared to LC patients. Addressing patient-, surgeon-, and system-level factors associated with intra/postoperative complications and applying recently promulgated safe cholecystectomy strategies coupled with advanced imaging modalities like fluorescence cholangiography to RAC may improve patient outcomes.

Abstract
OBJECTIVES Artificial intelligence (AI) has numerous applications in surgical quality assurance. We assessed AI accuracy in evaluating the critical view of safety (CVS) and intraoperative events during laparoscopic cholecystectomy. We hypothesized that AI accuracy and intraoperative events are associated with disease severity. METHODS One thousand fifty-one laparoscopic cholecystectomy videos were annotated by AI for disease severity (Parkland Scale), CVS achievement (Strasberg Criteria), and intraoperative events. Surgeons performed focused video review on procedures with ≥1 intraoperative events (n = 335). AI versus surgeon annotation of CVS components and intraoperative events were compared. For all cases (n = 1051), intraoperative-event association with CVS achievement and severity was examined using ordinal logistic regression. RESULTS Using AI annotation, surgeons reviewed 50 videos/hr. CVS was achieved in ≤10% of cases. Hepatocystic triangle and cystic plate visualization was achieved more often in low-severity cases (P < 0.03). AI-surgeon agreement for all CVS components exceeded 75%, with higher agreement in high-severity cases (P < 0.03). Surgeons agreed with 99% of AI-annotated intraoperative events. AI-annotated intraoperative events were associated with both disease severity and number of CVS components not achieved. Intraoperative events occurred more frequently in high-severity versus low-severity cases (0.98 vs 0.40 events/case, P < 0.001). CONCLUSIONS AI annotation allows for efficient video review and is a promising quality assurance tool. Disease severity may limit its use and surgeon oversight is still required, especially in complex cases. Continued refinement may improve AI applicability and allow for automated assessment.

Abstract
Background: Gallstone disease is common in India, and since primary management involves surgery, it is one of the most commonly performed surgeries by a general surgeon either laparoscopically or open. There are various factors which are responsible for intra- and post-operative complications. These factors result in significant injuries which cause serious post-operative complications. Amongst them, benign biliary stricture is one such significant complication which is primarily managed by open surgery, but since advent of laparoscopy, there has been an increased interest in doing this repair laparoscopically. Materials and Methods: This is a retrospective study of 16 patients having obstructive jaundice due to benign biliary stricture on magnetic resonance cholangiopancreatography who were operated consecutively over the past 10 years laparoscopically and underwent laparoscopic Roux-en-Y hepaticojejunostomy. Results: All patients underwent laparoscopic hepaticojejunostomy. The mean surgical time was 280 min, and the mean blood loss was 176 ml. In the post-operative period, most of the patients were started orally after 48 h; four had atelectasis, eight had surgical site infection, none had seroma and two had bile leak. All post-operative complications responded to conservative management. Conclusion: The study demonstrates that laparoscopic surgery for benign biliary strictures is safe and feasible with acceptable results.

Abstract
Bile duct injury remains the most serious complication of laparoscopic cholecystectomy (LC), the main cause was misidentification of cystic duct (CD). The aim of this study was to evaluate the effectiveness and security of retrograde tracing along "cystic duct" (RTACD) method for the prevention of biliary misidentification injury in LC. The conception of RTACD method was first described and then illustrated by simulation dissection with extrahepatic biliary structure charts. A total of 840 patients undergoing LC were selected. After the "CD" was separated during operation, its authenticity was identified by RTACD method according to its course and origin. The "CD" can be clipped/divided only when it was identified to be true CD. Among 840 patients, the initially separated "CD" was identified as actual CD in 831 cases, common hepatic (bile) duct in six cases, accessory right posterior sectoral duct in two cases, and right haptic duct in one case. LCs were successfully finished in 837 patients, and converted to open cholecystectomy in three cases. The average operation time was 64.23 min (range 25-225 min), and the average blood loss was 8.07 ml (range 2-200 ml). No biliary misidentification injury was found. All patients recovered smoothly. No jaundice or abdominal pain was noted in the patients during 1-19 months follow-up. RTACD method is a safe and effective new technique of preventing biliary misidentification injury.

Abstract
BACKGROUND Intraoperative cholangiography (IOC), even though is an important tool in biliary surgery, it is still a matter of debate when used as a routine procedure, this supported in the surgical and legal safety for the patient and the surgeon. We do not have knowledge of the real expositional risk of the surgeon to ionizing radiation (IR) during the cholangiography procedure, because many surgeons do not use protection and dosimeters, so we cannot determine occupational radiation exposure. STUDY DESIGN A prospective cohort study was conducted to assess the radiation exposure of a group of surgeons performing laparoscopic cholecystectomy, regardless of the type of surgery (elective or urgent). A descriptive, bivariate analysis was made, with a linear simulation model for prediction. We evaluate the frequency of use of protection-established devices, number of images per surgery, and frequency of IOC. The radiation received was measured by dosimeters at different distances. RESULTS A total of 597 IOC were made in the evaluated period. Mean number of IOC per surgeon was five monthly, with an average of two images per surgery. 60% of surgeons did not use protection devices during IOC. The surgeon radiation received was 0.147 millisieverts (mSv) at 1 m, 0.039 mSv at 1.6 m, and 0.007 mSv at 2.5 m. CONCLUSIONS The volume, quality, and sufficiency of protection, coupled with the distance to the X-ray generator, are the major determinants to define the exposure to IR. We can predict the annual ionizing radiation according to the volume of the accomplished procedures. Although exposure doses are really low and make this a safe procedure, continuous exposure can lead to serious illnesses.

Abstract
BACKGROUND Bile duct injury during laparoscopic cholecystectomy persists as a significant problem in general surgery, resulting in complex injuries, arterial damage, and post repair strictures. METHODS We performed a retrospective analysis between 2 eras of bile duct injury repairs: 1987 to 2001 (n = 58) and 2002 to 2016 (n = 52) using logistic regression analyses to assess presentation, repair complexity, and outcomes. RESULTS No differences in demographics, incidence of cholecystitis, conversion, time to presentation, level of injury, or arterial injury were identified. The second era had an increase in patient age, transhepatic catheter use, prior repair, and utilization of complex repairs. This approach resulted in equivalent complications and mortality rates with increased resource utilization but a lesser incidence of post-repair strictures (P = .004). Regression modeling correlated strictures to prior operative repairs (OR 4.25; P = .016) and a protective effect of repairs performed in the second era (OR 0.23; P = .045). CONCLUSION The second era identified a decreasing trend of attempted repairs by referring surgeons but an increase in transhepatic catheters and complex repairs resulting in lesser rates of post-repair stricture. Final regression modeling confirmed increased operative experience decreased post-repair stricture reaffirming the benefits of early identification and referral of bile duct injuries to an experienced hepatobiliary surgeon at a specialty center.

Abstract
Introduction Cholecystectomy is associated with the risk of bile duct injury (BDI). The nature of the injury in laparoscopic cholecystectomy (LC) cases seems to be more serious. Aim We present an analysis of long-term results of the treatment of patients who underwent operations at our department due to iatrogenic excision of a part of the bile duct (EPBD). Material and methods Out of all 120 patients treated for BDI in our department we selected a group of 40 with EPBD. In all cases the corrective operation was hepaticojejunostomy. The median follow-up time was 157 (56–249) months. We evaluated risk factors for EPBD during LC compared to open cholecystectomy (OC). Results Among bile duct injuries referred to our centre, EPBD occurred more frequently during LC (46.7%) compared to OC (11%), p < 0.001. Injuries located in the hepatic hilum occurred more often in the case of LC (68.6%) than OC (20%), p = 0.056. We did not find a difference in the frequency of EPBD between LC and OC groups depending on the presence of acute or chronic cholecystitis. The narrow common hepatic duct was reported more frequently in the LC (68.6%) vs. OC (20%) group, p = 0.056. Satisfactory long-term reconstructive treatment results were observed in 36 (90%) of 40 patients. Conclusions Excision of a part of the bile duct occurs more often during LC than OC. It is often located in the hepatic hilum. Presence of a narrow common hepatic duct is a risk factor for EPBD during LC. Large diameter hepaticojejunostomy is a reconstructive procedure that promises good long-term results.

Abstract
INTRODUCTION Attempting to decrease iatrogenic injuries and preventable harm, safety initiatives have become a priority in surgery. For adult hepatobiliary surgery, it has become common to study and consider "error traps" or common pitfalls that exist for laparoscopic cholecystectomy.1-4 Extending this work to children, we have attempted to apply some of these initiatives by identifying error traps common to the care of patients born with anorectal malformations (ARM). METHODS Five error traps were identified based on a retrospective analysis of operative records and radiographic studies from 398 re operative ARM cases performed by the authors. Once identified, the authors constructed a specific safety plan for each trap to promote a culture that will hopefully prevent ARM iatrogenic injuries. RESULTS The identified error traps are: 1) creation of a colostomy too distal in the sigmoid colon, 2) inaccurate distal colostogram and definition of the patient's preoperative anatomy 3) absence of a Foley catheter during the repair of an ARM in males and the hazards of separating the anterior rectal wall from the genito-urinary (GU) tract 4) mismanagement of a post-operative anal stricture following an ARM reconstructive procedure 5) limited or unstructured follow up of these patients. For each of the five traps the authors present suggestions for their avoidance. CONCLUSION The repair on an anorectal malformation is an elective procedure and while not completely avoidable, there should be little tolerance for iatrogenic injury and preventable harm. A culture of safety should be followed, beginning with a recognition of the common error traps associated with ARM procedures.

Abstract
Objectives Laparoscopic cholecystectomy - associated bile duct injury is a clinical problem with bad outcome. The study aimed to analyze the outcome of surgical management of these injuries. Patients and methods We retrospectively analyzed 69 patients underwent surgical management of laparoscopic cholecystectomy related major bile duct injuries in the period from the beginning of 2013 to the beginning of 2018. Results Regarding injury type; the Leaking, Obstructing, leaking + obstructing, leaking + vascular, and obstructing + vascular injuries were 43.5%, 27.5%, 18.8%, 2.9%, and 7.2% respectively. However, the Strasberg classification of injury was as follow E1 = 25, E2 = 32, E3 = 8, and E4 = 4. The definitive procedures were as follow: end to end biliary anastomosis with stenting, hepaticojejunostomy (HJ) with or without stenting, and RT hepatectomy plus biliary reconstruction with stenting in 4.3%, 87%, and 8.7% of patients respectively. According to the time of definitive procedure from injury; the immediate (before 72 h), intermediate (between 72 h and 1.5months), and late (after1.5 months) management were 13%, 14.5%, and 72.5% respectively. The hospital and/or 1month (early) morbidity after definitive treatment was 21.7%, while, the late biliary morbidity was 17.4% and the overall mortality was 2.9%, on the other hand, the late biliary morbidity-free survival was 79.7%. On univariate analysis, the following factors were significant predictors of early morbidity; Sepsis at referral, higher Strasberg grade, associated vascular injury, right hepatectomy with biliary reconstruction as a definitive procedure, intra-operative bleeding with blood transfusion, liver cirrhosis, and longer operative times and hospital stays. However, the following factors were significantly associated with late biliary morbidity: Sepsis at referral, end to end anastomosis with stenting, reconstruction without stenting, liver cirrhosis, operative bleeding, and early morbidity. Conclusion Sepsis at referral, liver cirrhosis, and operative bleeding were significantly associated with both early and late morbidities after definitive management of laparoscopic cholecystectomy related major bile duct injuries, so it is crucial to avoid these catastrophes when doing those major procedures.

Abstract
Objectives Laparoscopic cholecystectomy - associated bile duct injury is a clinical problem with bad outcome. The study aimed to analyze the outcome of surgical management of these injuries. Patients and methods We retrospectively analyzed 69 patients underwent surgical management of laparoscopic cholecystectomy related major bile duct injuries in the period from the beginning of 2013 to the beginning of 2018. Results Regarding injury type; the Leaking, Obstructing, leaking + obstructing, leaking + vascular, and obstructing + vascular injuries were 43.5%, 27.5%, 18.8%, 2.9%, and 7.2% respectively. However, the Strasberg classification of injury was as follow E1 = 25, E2 = 32, E3 = 8, and E4 = 4. The definitive procedures were as follow: end to end biliary anastomosis with stenting, hepaticojejunostomy (HJ) with or without stenting, and RT hepatectomy plus biliary reconstruction with stenting in 4.3%, 87%, and 8.7% of patients respectively. According to the time of definitive procedure from injury; the immediate (before 72 h), intermediate (between 72 h and 1.5months), and late (after1.5 months) management were 13%, 14.5%, and 72.5% respectively. The hospital and/or 1month (early) morbidity after definitive treatment was 21.7%, while, the late biliary morbidity was 17.4% and the overall mortality was 2.9%, on the other hand, the late biliary morbidity-free survival was 79.7%. On univariate analysis, the following factors were significant predictors of early morbidity; Sepsis at referral, higher Strasberg grade, associated vascular injury, right hepatectomy with biliary reconstruction as a definitive procedure, intra-operative bleeding with blood transfusion, liver cirrhosis, and longer operative times and hospital stays. However, the following factors were significantly associated with late biliary morbidity: Sepsis at referral, end to end anastomosis with stenting, reconstruction without stenting, liver cirrhosis, operative bleeding, and early morbidity. Conclusion Sepsis at referral, liver cirrhosis, and operative bleeding were significantly associated with both early and late morbidities after definitive management of laparoscopic cholecystectomy related major bile duct injuries, so it is crucial to avoid these catastrophes when doing those major procedures. Sepsis at referral was associated with poor outcome after management of LC related MBDIs. Liver cirrhosis and operative bleeding were associated with poor outcome after management of these injuries. It is crucial to avoid these catastrophes when doing those major procedures.

[PMID: 29943057 DOI: 10.1007/s00464-018-6300-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2018] [Accepted: 06/18/2018] [Indexed: 12/14/2022]
Abstract
BACKGROUND Multiport laparoscopic cholecystectomy (MLC) is the gold standard technique for cholecystectomy. In order to reduce postoperative pain and improve cosmetic results, the application of the single-incision laparoscopic cholecystectomy (SILC) technique was introduced, leading surgeons to face important challenges. Robotic technology has been proposed to overcome some of these limitations. The purpose of this review is to assess the safety of single-incision robotic cholecystectomy (SIRC) for benign disease. METHODS An Embase and Pubmed literature search was performed in February 2017. Randomized controlled trial and prospective observational studies were selected and assessed using PRISMA recommendations. Primary outcome was overall postoperative complication rate. Secondary outcomes were postoperative bile leak rate, total conversion rate, operative time, wound complication rate, postoperative hospital stay, and port site hernia rate. The outcomes were analyzed in Forest plots based on fixed and random effects model. Heterogeneity was assessed using the I2 statistic. RESULTS A total of 13 studies provided data about 1010 patients who underwent to SIRC for benign disease of gallbladder. Overall postoperative complications rate was 11.6% but only 4/1010 (0.4%) patients required further surgery. A postoperative bile leak was reported in 3/950 patients (0.3%). Conversion occurred in 4.2% of patients. Mean operative time was 86.7 min including an average of 42 min should be added as for robotic console time. Wound complications occurred in 3.7% of patients. Median postoperative hospital stay was 1 day. Port site hernia at the latest follow-up available was reported in 5.2% of patients. CONCLUSIONS The use of the Da Vinci robot in single-port cholecystectomy seems to have similar results in terms of incidence and grade of complications compared to standard laparoscopy. In addition, it seems affected by the same limitations of single-port surgery, consisting of an increased operative time and incidence of port site hernia.

Abstract
Laparoscopic cholecystectomy is considered as the gold standard in the treatment of gallbladder disease. Laparoscopy presents significant advantages including decreased hospital stay, better aesthetic results, faster rehabilitation, less pain, reduced cost, and increased patient satisfaction. The complications' prevalence is low; however, the overall serious complication rate seems to be higher compared to open cholecystectomy, despite the increasing experience. Diaphragmatic injury following laparoscopic cholecystectomy is an extremely rare complication, and a high index of clinical suspicion is necessary to diagnose this situation that has a variety of clinical presentations and might be life-threatening. We present a unique case of postlaparoscopic cholecystectomy diaphragm defect with late onset. The clinical findings included those of respiratory distress syndrome along with small bowel incarceration and peritonitis.

Abstract
BACKGROUND Bile duct injury (BDI) remains the most dreaded complication following cholecystectomy with serious repercussions for the surgeon, patient and entire healthcare system. In the absence of registries, the true incidence of BDI in the United States remains unknown. We aim to identify the incidence of BDI requiring operative intervention and overall complications after cholecystectomy. METHODS Utilizing the Truven Marketscan® research database, 554,806 patients who underwent cholecystectomy in calendar years 2011-2014 were identified using ICD-9 procedure and diagnosis codes. The final study population consisted of 319,184 patients with at least 1 year of continuous enrollment and who met inclusion criteria. Patients were tracked for BDI and other complications. Hospital cost information was obtained from 2015 Premier data. RESULTS Of the 319,184 patients who were included in the study, there were a total of 741 (0.23%) BDI identified requiring operative intervention. The majority of injuries were identified at the time of the index procedure (n = 533, 72.9%), with 102 (13.8%) identified within 30-days of surgery and the remainder (n = 106, 14.3%) between 31 and 365 days. The operative cumulative complication rate within 30 days of surgery was 9.84%. The most common complications occurring at the index procedure were intestinal disorders (1.2%), infectious (1%), and shock (0.8%). The most common complications identified within 30-days of surgery included infection (1.5%), intestinal disorders (0.7%) and systemic inflammatory response syndrome (SIRS) (0.7%) for cumulative rates of infection, intestinal disorders, shock, and SIRS of 2.0, 1.9, 1.0, and 0.8%, respectively. CONCLUSION BDI rate requiring operative intervention have plateaued and remains at 0.23% despite increased experience with laparoscopy. Moreover, cholecystectomy is associated with a 9.84% 30-day morbidity rate. A clear opportunity is identified to improve the quality and safety of this operation. Continued attention to educational programs and techniques aimed at reducing patient harm and improving surgeon skill are imperative.

Abstract
Laparoscopic cholecystectomy is a common surgical procedure, and remains the gold standard for the management of benign gallbladder and biliary disease. While this procedure can be technically straightforward, it can also represent one of the most challenging operations facing surgeons. This dichotomy of a routine operation performed so commonly that poses such a hidden risk of severe complications, such as bile duct injury, must keep surgeons steadfast in the pursuit of safety. The "difficult gallbladder" requires strict adherence to the Culture of Safety in Cholecystectomy, which promotes safety first and assists surgeons in managing or avoiding difficult operative situations. This review will discuss the management of the difficult gallbladder and propose the use of subtotal fenestrating cholecystectomy as a definitive option during this dangerous situation.

Abstract
INTRODUCTION The timing of laparoscopic cholecystectomy for acute cholecystitis remains an issue for debate amongst general surgeons. The aim of this study was to compare clinical outcomes between early and delayed cholecystectomy for acute cholecystitis. The primary outcome measures included mortality rates, complication rates, length of hospital stay and conversion rates to open procedures. MATERIALS AND METHODS A search of electronic databases was performed for randomised controlled trials. Fifteen studies were included. RESULTS Early surgery has a decreased risk of wound infections (RR 0.57, 95 % CI 0.35-0.93, p=0.01) compared with delayed surgery but no difference in mortality, bile duct injuries, bile duct leaks and the risk of conversion to open surgery. Of patients in the delayed group, 9.7 % failed initial non-operative management and underwent emergency LC. Early surgery had a significantly reduced total hospital stay and mean hospital costs compared with delayed surgery. CONCLUSION Early laparoscopic cholecystectomy in acute cholecystitis demonstrated decreased incidence of wound infections, a shorter total length of stay and decreased costs with no difference in the rates of mortality, bile duct injuries, bile leaks and conversions. These results support that early laparoscopic cholecystectomy is the best care and should be considered a routine in patients presenting with acute cholecystitis.

Abstract
BACKGROUND "Tilt" of surgical view was commonly shown on the monitor due to unintentional rotation of camera along its long axis by camera driver. Surgeons may be influenced on identification of anatomical structures by the tilt vision. We aimed to analyze the surgical records and videos of laparoscopic surgery, and to reveal the correlation between intraoperative complications and tilt view. METHODS A series of 425 consecutive patients who received laparoscopic low anterior resection and abdominoperineal resection were studied, and 398 surgery videos were reviewed. Still pictures showing intraoperative injury were selected. A method was established to measure tilt angle in the still pictures according to the reference line based on several anatomic landmarks. The patients were grouped with two methods according to different study purposes. Incidence of intraoperative complication and tilt angle were calculated, and statistical analysis was performed. RESULTS The incidence of intraoperative complications was 8.3%. Tilt of the surgical field at different degrees (<15°, 15°-30° and >30°) was found in a relatively high rate in these surgery videos (31.4%). Compared with controls, comparatively bigger tilt angles were found in all cases of complication group. It is interesting to note that intraoperative complications happened more often when the tilt angle was in the range of 15°-30° (72.7%) than >30° (18.2%). We also noted a high incidence of complication (72.7%), while tilt angle was over 15° (26%) in the first 100 cases; comparatively a steady declining low rate of complication occurrence (5-7%) and also tilt angle over 15° (9-11%) were noted in the later 298 cases. CONCLUSIONS Rotation of camera is common during laparoscopic procedures. The tilt view increased the risk of laparoscopic procedures. Tilt angle at 15-30° is the most dangerous rotation for laparoscopic surgeries. Therefore, we propose the "Gravity Line Strategy" principle as one of the basic operating criteria to correct the tilt angle.

Abstract
BACKGROUND Percutaneous transhepatic balloon dilatation is an alternative to surgery when benign bilioenteric strictures (BBES) are inaccessible to endoscopic treatment. Our primary objective was to report long-term patency of balloon-dilated BBES. METHODS A total of 110 consecutive patients with 155 BBES had percutaneous transhepatic complete drainage of all biliary territories, balloon dilatation, and catheter stenting. Intracorporeal electrohydraulic lithotripsy treated associated biliary stones. Biliary drains were removed when no residual balloon waists were observed on at least 2 consecutive sessions, 6 weeks apart. RESULTS A total of 109 of 110 patients had complete drainage. Forty-five patients had successfully treated associated stones. Eleven patients had short-term complications. No patients died. The median follow-up period was 59 months (range, .5-278 mo). Twenty-three patients were lost to follow-up evaluation. Thirteen patients had recurrent biliary obstruction (15%). Life-table analysis showed 90.9% bilioenteric patency after 2,697 days. CONCLUSIONS Percutaneous balloon dilatation and calibration of BBES provides acceptable morbidity and low long-term stricture recurrence.

Abstract
OBJECTIVE Single incision laparoscopic cholecystectomy (SILC) has recently emerged as an option for selected patients undergoing gallbladder removal. While SILC appears safe when performed by experienced surgeons under controlled conditions, there are no studies evaluating the SILC learning curve for incorporation into resident education and the effect on OR efficiency. DESIGN, SETTING, AND PARTICIPANTS Chief residents were taught and evaluated by a single attending surgeon facile with SILC techniques. Residents were transitioned from assistants to primary surgeon during their clinical rotation. Outcomes data were prospectively tabulated compared with data from standard laparoscopic SLC and attending surgeon SILC outcomes. The setting was an academic, tertiary care teaching hospital. Participants were chief residents rotating on hepatobiliary surgery service. Residents previously had demonstrated mastery of basic laparoscopic surgical techniques. RESULTS Seven chief residents were evaluated with a total of 49 SILCs with a mean of 7 (range 5-12) SILCS/resident. Five conversions to SLC occurred, all within the first 3 SILCs performed by the resident as operative surgeon. Mean blood loss was 30 mL. Median length of stay was <1 day. Average length of operation increased after the first 2 cases, reflecting the transition of the attending surgeon from primary surgeon to assistant role. By the fifth case, operative times returned to the attending surgeon SILC baseline and historical operative times for SLC at our institution. Factors associated with longer-length of surgery were increasing BMI and presence of acute or chronic cholecystitis, choledocholithiasis, and use of intraoperative cholangiogram. Five postoperative complications occurred and were not associated with position along the resident's learning curve. One death occurred due to metastatic laryngeal cancer within 30 days of SILC. CONCLUSIONS Residents can safely be taught the techniques of SILC with minimal disruption to operating room efficiency. Residents already proficient in the use of standard laparoscopic techniques transition to SILC quickly with a short learning curve and proper instruction.

Abstract
INTRODUCTION Bile duct injury remains constant in the era of laparoscopic cholecystectomy and misidentification of structures remains one of the most common causes of such injuries. Abnormalities in liver segment IV, which is fully visible during laparoscopic cholecystectomy, may contribute to misidentification as proposed herein. METHODS We describe the case of a 36-year-old female who had a bile duct injury during a laparoscopic cholecystectomy where the surgeon noticed an unusually small distance between the gallbladder and the round ligament. RESULTS We define hypoplasia of liver segment IV as well as describe the variation of the biliary anatomy in the case. We also intend to fit it in a broader spectrum of developmental anomalies that have both hyopoplasia of some portion of the liver and variations in gallbladder and bile duct anatomy that may contribute to bile duct injury. DISCUSSION To our knowledge, hypoplasia of liver segment IV has not been suggested in the literature as a risk factor for bile duct injury except in the extreme case of a left-sided gallbladder. Surgeons should be vigilant during laparoscopic cholecystectomy when they become aware of an unusually small distance between the gallbladder bed and the round ligament prior to beginning their dissection, variations in the common bile duct and cystic duct should be expected.

Abstract
Most asymptomatic gallstone carriers require no therapy. Laparoscopic cholecystectomy is the best definitive therapy for symptomatic gallstone disease. Selective laparoscopic cholecystectomy can provide secondary prevention of symptoms and complications in certain instances (in a complex clinical setting such as sickle cell disease or to prevent gallbladder carcinoma from developing in those at risk with large gallstones or with a calcified gallbladder). Primary prevention is unproven but focuses on early identification and risk alteration to decrease the possibility of developing gallstones. Ursodeoxycholic acid has a limited role for stone dissolution but can prevent stone development in severe obesity during rapid weight reduction with diet or after bariatric surgery. Endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy represents the therapeutic cornerstone for managing severe pancreatitis and cholangitis.

Abstract
Single incision laparoscopic cholecystectomy (SILC) is a new minimally-invasive technique that has recently been developed to address several disease processes of the gallbladder. However, the safety and feasibility of this technique are still being evaluated. Utilizing a “two-port” technique with transabdominal suture retraction and a rigorous adherence to the critical view of safety, we evaluated our experience in a prospectively maintained database and compared this with standard laparoscopic cholecystectomy (SLC) over the same period. SILC was completed successfully in 87 per cent of patients. Operative times were found to be similar between SLC and SILC (75 and 76 minutes, respectively; P = 0.12). Operative blood loss, hospital stay, and short-term complications were not statistically different between SILC and SLC. Cholangiograms, obtained on a selective basis, were performed in 19 per cent of SILCs. No bile duct injuries occurred during SILC or SLC. Although our aggregate number is not enough to accurately assess the rate or safety of bile duct injuries, SILC seems to be safe and feasible when evaluating other metrics and does not seem to interfere with operative efficiency compared with SLC.

Abstract
BACKGROUND Injuries to the bile duct during laparoscopic cholecystectomy are often a cause of malpractice litigations. METHODS A total of 13 legal verdicts as a result of bile duct injury from 1996 to 2009 were reviewed. Comments on the verdicts and the opinions of expert witnesses were analyzed. RESULTS Out of 13 claims, 7 were upheld and 6 were rejected. Most expert witnesses from 1996 to 2002 stated that not carrying out a cholangiography and insufficient preparation of the cystic duct constituted a performance below the standard of care expected. Expert witness testimonies from 2004 to 2009, however, regarded injury to the bile duct as predominantly inherent to treatment. CONCLUSION With the expansion and acceptance of laparoscopic interventions, changes in the results of malpractice litigation have become evident. In contrast to the phase during establishment of the technology, an injury to the bile duct is nowadays judged predominantly as inherent to treatment.

Abstract
BACKGROUND Numerous recent reports describe the performance of laparoscopic procedures through a single incision. Although the feasibility of this approach for a variety of procedures is currently being established, little data are available regarding safety. CASE REPORT A 65-year-old female patient who was transferred from an outside institution had undergone a single incision laparoscopic cholecystectomy that resulted in biliary tract and vascular injuries. METHODS The patient was transferred with a known bile duct injury on the first postoperative day following single incision laparoscopic cholecystectomy. Review of her magnetic resonance imaging and percutaneous transhepatic cholangiogram studies showed a Bismuth type 3 bile duct injury. Hepatic angiogram demonstrated an occlusion of the right hepatic artery with collateralization from the left hepatic artery. She was initially managed conservatively with a right-sided external biliary drain, followed 6 weeks later by a Hepp-Couinaud procedure to reconstruct the biliary tract. CONCLUSION As new techniques evolve, it is imperative that safety, or potential side effects, or both safety and side effects, be monitored, because no learning curve is established for these new techniques. In these initial stages, surgeons should have a low threshold to add additional ports when necessary to ensure that procedures are completed safely.

Single-incision laparoscopic cholecystectomy: initial experience with critical view of safety dissection and routine intraoperative cholangiography. J Am Coll Surg 2010; 211:1-7.

Abstract
BACKGROUND Single-incision laparoscopic cholecystectomy (SILC) is emerging as a potentially less invasive alternative to standard laparoscopic cholecystectomy and natural orifice transluminal endoscopic surgery cholecystectomy. As this technique is more widely used, it is important to maintain well-established practices of the critical view of safety (CVS) dissection and intraoperative cholangiography (IOC). We present our initial experience with SILC using CVS dissection and routine IOC. STUDY DESIGN Fifty-four patients with biliary colic were offered SILC, which was performed through the umbilicus. CVS with photo documentation was attained before clipping and transecting the cystic structures. IOC was done using various needle puncture techniques. Assessment of CVS was carried out by independent surgeon review of operative still photos or videos using a 3-point grading scale: visualization of only 2 ductal structures entering the gallbladder; a clear triangle of Calot; and separation of the base of the gallbladder from the cystic plate. RESULTS SILC was performed in 54 patients (15 male and 39 female). Six patients required 1 supplementary 3- or 5-mm port. Complete IOC was successful in 50 of 54 patients (92.6%). CVS was achieved at the time of operation in all 54 patients. Photo documentation review confirmed 3 of 3 CVS criteria in 32 (64%) patients, 2 of 3 in 12 patients (24%), 1 of 3 in 3 patients (6%), and 0 in 3 patients (6%). CONCLUSIONS As laparoscopic cholecystectomy becomes less invasive, proven safe dissection techniques should be maintained. Dissection to obtain the CVS should be the goal of every patient and IOC can be accomplished in a high percentage of patients. This approach places patient safety considerations foremost in the evolution of minimally invasive cholecystectomy.

Abstract
Iatrogenic porta hepatis transection is a rare but devastating surgical complication. There are no systematic studies examining the best treatment strategy in patients with this injury. We report two cases of transection of all three portal structures, one during an open right adrenalectomy and another during a laparoscopic cholecystectomy, both of which were transferred to our tertiary care center hours postinjury. Diagnostic imaging and exploration revealed nonsalvageable livers, and both patients underwent total hepatectomies and portocaval shunting. Donor livers were available 12 to 20 hours after United Network for Organ Sharing Status 1 listing and both patients survived their postoperative course with 2- and 6-year follow up to date. Two-stage total hepatectomy with portocaval shunting followed by liver transplantation should be considered for patients presenting with porta hepatis transection.

Abstract
Iatrogenic biliary injuries most commonly occur during laparoscopic cholecystectomy. Biliary injuries are complex problems requiring a multidisciplinary approach with surgeons, radiologists, and gastroenterologists knowledgeable in hepatobiliary disease. Mismanagement can result in lifelong disability and chronic liver disease. Given the unforgiving nature of the biliary tree, favorable outcome requires a well-thought-out strategy and attention to detail.

Abstract
Bile duct injury is an important unsolved problem of laparoscopic cholecystectomy, occurring with unacceptable frequency even in the hands of experienced surgeons. This suggests that a systemic predisposition to the injury is intrinsic to cholecystectomy and indicates that an analysis of the psychology and heuristics of surgical decision-making in relation to duct identification may be a guide to prevention. Review of published reports on laparoscopic bile duct injury from 1997 to 2007 was carried out. An analysis was also carried out of the circumstances of the injuries in 49 patients who had transection of an extrahepatic bile duct and who were referred for reconstruction or were assessed in a medicolegal context. Special emphasis was placed on identifying the possible psychological aspects of duct misidentification. Review of published work showed an emphasis on the technical aspects of correct identification of the cystic duct, with few papers addressing the heuristics and psychology of surgical decision-making during cholecystectomy. Duct misidentification was the cause of injury in 42 out of the 49 reviewed patients (86%). The injury was not recognized at operation in 70% and delay in recognition persisted into the postoperative period in 57%. Underestimation of risk, cue ambiguity and visual misperception ('seeing what you believe') were important factors in misidentification. Delay in recognition of the injury is a feature consistent with cognitive fixation and plan continuation, which help construct and sustain the duct misidentification during the operation and beyond. Changing the 'culture' of cholecystectomy is probably the most effective strategy for preventing laparoscopic bile duct injury, especially if combined with new technical approaches and an understanding of the heuristics and psychology of the duct misidentification error. Training of surgeons for laparoscopic cholecystectomy should emphasize the need to be alert for cues that the incorrect duct is being dissected or that a bile duct injury might have occurred. Surgeons may also be trained to accept the need for plan modification, to seek cues that refute a given hypothesis and to apply 'stopping rules' for modifying or converting the operation.

Abstract
OBJECTIVE To determine the inter-rater agreement of expert witness testimonies in bile duct injury malpractice litigation. BACKGROUND DATA Malpractice litigation is an increasing concern in modern surgical practice. As most of the lawyers are not educated in medicine, expert witnesses are asked to testify about negligence of care in most jurisdictions. Although expert witnesses greatly determine the outcome of a claim, the reliability of expert testimony may be arbitrary. METHODS Surgical expert witnesses independently assessed whether negligence of care occurred by reviewing the complete medical history of closed litigation cases. All cases concerned iatrogenic bile duct injury, which occurred during laparoscopic cholecystectomy. The level of agreement was measured and case characteristics associated with negligence were determined. RESULTS Thirteen independent experts reviewed 10 closed litigation cases. In 1 of the 10 cases, full agreement was observed. In 7 of the 10 cases, the highest percentage of agreeing experts was 53% or less. Chance-corrected levels of agreement were in the slight to fair range (Kendall W coefficient of concordance = 0.16-0.25). Disease-related mortality was associated with judgments on negligence (P = 0.02). Judgments on negligence of care were not associated with delay in diagnosis or the severity of injury. Experts with more years of clinical experience agreed more about negligence. Experts working in an academic setting agreed less than experts working in a teaching hospital. Finally, 8 of the 13 experts plead for the assignment of more than 1 expert witness to review and comment in a surgical litigation case. CONCLUSIONS The reliability of expert witness testimonies in bile duct injury litigation is frail. Defendants, plaintiffs, experts, and lawyers should be aware of the drawbacks of expert witness testimonies. Raising consensus concerning the standards of surgical care may be required to improve agreement in judgments on negligence.

Abstract
Major bile duct injury (BDI) rates remain in the range of 0.3 to 0.5 per cent for laparoscopic cholecystectomy (LC). The dominant surgical technique worldwide continues to be the “infundibular” technique of dissection that was popularized in the early 1990s. Proponents of the “critical view of safety” (CV) technique have suggested that most of these injuries are avoidable. The objective of our study was to determine whether routine use of the CV technique reduced the observed/expected single-institution rate of major BDI over a 5-year period in a teaching hospital. All patients (n = 3042) who underwent LC for any indication at one institution over a 60-month period were identified by database search. Major BDI was identified by Common Procedural Terminology codes indicating operative repair and confirmed by review of medical records. One patient sustained a transection–excision of the common duct requiring hepaticoduodenostomy. Based on published data, the observed BDI rate was one in nine to one in 15 of the expected rate. This represents an order-of-magnitude improvement in the safety of LC at a single institution where the majority of cases were performed by residents. We suggest that the “critical view” technique should be widely adopted.

The routine use of laparoscopic ultrasound decreases bile duct injury: a multicenter study. Surg Endosc 2008; 23:384-8.

Abstract
OBJECTIVE Laparoscopic ultrasound (LUS) has been used for over 15 years to screen the bile duct (BD) for stones and to delineate anatomy during laparoscopic cholecystectomy (LC). LUS as a modality to prevent BD injury has not been investigated in a large series. This study evaluated the routine use of LUS to determine its effect on preventing BD injury. METHODS A multicenter retrospective study was performed by reviewing clinical outcome of LC in which LUS was used routinely. RESULTS In five centers, 1,381 patients underwent LC with LUS. LUS was successful to delineate and evaluate the BD in 1,352 patients (98.0%), although it was unsuccessful or incomplete in 29 patients (2.0%). LUS was considered remarkably valuable to safely complete LC, avoiding conversion to open, in 81 patients (5.9%). The use of intraoperative cholangiography (IOC) varied depending on centers; IOC was performed in 504 patients (36.5%). For screening of BD stones (which was positive in 151 patients, 10.9%), LUS had a false-positive result in two patients (0.1%) and a false-negative result in five patients (0.4%). There were retained BD stones in three patients (0.2%). There were minor bile leaks from the liver bed in three patients (0.2%). However, there were no other BD injuries including BD transection (0%). Retrospectively, IOC was deemed necessary in 25 patients (1.8%) to complete LC in spite of routine LUS. CONCLUSION LUS can be performed successfully to delineate BD anatomy in the majority of patients. The routine use of LUS during LC has obviated major BD injury, compared to the reported rate (1 out of 200-400 LCs). LUS improves the safety of LC by clarifying anatomy and decreasing BD injury.

Abstract
BACKGROUND Concomitant hepatic artery injury is a rare but severe complication associated with bile duct injury during laparoscopic cholecystectomy (LC). METHODS Sixty patients referred with biliary injury after LC between April 1998 and December 2005 were divided into two groups according to the time elapsed between injury and definitive surgical revision; patients in group 1 were referred early (within 4 days) after operation and those in group 2 were referred later. Hepatic rearterialization was performed in addition to biliary reconstruction when technically possible. RESULTS Damage to the hepatic artery was detected in ten patients. Hepatic rearterialization was carried out in five patients by end-to-end anastomosis (one), or by using an autologous graft (three) or allogeneic vascular graft (one). Three patients in group 2 underwent right hemihepatectomy without arterial reconstruction owing to liver necrosis or lobar atrophy. Three of ten patients died from postoperative complications. CONCLUSION Combined bile duct and hepatic artery injury during LC led to a complicated clinical course, with a high mortality rate. Reconstruction of the right hepatic artery might be helpful in reducing hepatic ischaemia, but is usually feasible only if the injury is identified early.

Abstract
AIM OF THE STUDY To analyze our experience with biliary injuries during cholecystectomy in order to determine associated risk factors, morbidity, and results after reconstruction. PATIENTS AND METHODS Review of the series of patients referred to our department for biliary injury during cholecystectomy over a 9-year period. Items regarding the type of lesion, risk factors, management, morbidity, and late results were recorded. RESULTS Fifteen patients were referred to our department for bile duct injury during cholecystectomy between 1997 and 2005 (14 by laparoscopy and four by laparotomy; nine women and nine men). The main surgical indication was biliary colic (n=8). Three patients were operated on in an emergency setting (for acute cholecystitis). In nine patients the gallbladder wall was inflammatory. Intraoperative cholangiography was performed in nine patients, but revealed just one injury. Lateral injury to the bile duct was the most frequent type of lesion. In nine patients, the injury was detected intraoperatively and a biliary drainage was left in place; five of them had a synchronic repair and three required later reconstruction. Nine patients had a delayed identification of biliary injury; six of them required a biliodigestive anastomosis. Two patients died, three had several episodes of acute cholangitis after reconstruction and two presented incisional hernia. CONCLUSION An inflammatory environment is the main risk factor for biliary injury during cholecystectomy. Bile duct injury is more frequent with laparoscopic cholecystectomy but can also occur with an open approach. Intraoperative cholangiography does not prevent biliary injuries nor detect them accurately. Biliary drainage can reduce morbidity for intraoperatively detected injuries and may be a sensitive approach for the surgeon with no hepatobiliary experience. Morbidity is increased in patients with delayed identification of the injury.

Abstract
BACKGROUND Medical liability is a great concern in current surgical practice. The medical liability system in the US is under discussion in surgical literature, as the system is associated with high costs and expensive liability premiums. The aim of this study was to evaluate the Dutch arbitration system for claims filed after bile duct injury (BDI). STUDY DESIGN Data were extracted from the largest Dutch insurance company for medical liability. Outcomes of the claim and factors associated with awarded financial compensation were determined. RESULTS BDI litigation after laparoscopic cholecystectomy occurred in 0.08% (+/- 0.02% SD) without a substantial increase. Currently, 88 of 133 claims are closed after a median duration of 2 years (range 5 months to 6.5 years). In 61 of 88 cases (69%) liability was rejected, and in 16 cases (18%) liability was acknowledged. Median compensation (in Euros) was euro 9.826,07 (range euro 15,88 to euro 55.301,06). Rejection of liability increased from 50% in the period 1994 to 1998 versus 72% in 2004 to 2006 (p = 0.023). Factors associated with recognition were patient employment (p = 0.005) and patient death (p = 0.01). Factors associated with an increase in financial compensation are delay in imaging (p = 0.033), delay in diagnosis (p = 0.009), and relaparotomy with repair in the initial hospital (p = 0.028). CONCLUSIONS The Dutch arbitration system for medical liability after BDI is associated with a short time to resolution and high rejection rates, and payments to BDI patients are low.

Abstract
BACKGROUND Different injury patterns of iatrogenic bile duct lesions after cholecystectomy have prompted the proposal of several different clinical classification systems. The aim of this study was to validate these systems comparatively. METHODS Results after surgical intervention for iatrogenic bile duct lesions in 74 consecutive patients at a tertiary referral centre were reviewed retrospectively. A new classification (Hannover classification) for iatrogenic bile duct lesions is proposed and compared with four other systems using the present clinical data. RESULTS Additional vascular lesions were found in 19 per cent. The hospital mortality rate was 3 per cent and the overall hospital complication rate after repair was 26 per cent. Sixteen of 74 patients required early surgical reintervention. The Hannover classification demonstrated a highly significant association between the discrimination of classifiable injury patterns and the different surgical treatments chosen (P < 0.005). The Strasberg and Neuhaus classifications do not consider vascular involvement, whereas the Stewart-Way, Siewert and Neuhaus systems do not discriminate between lesions at or above the bifurcation of the hepatic duct. CONCLUSION Additional vascular involvement and location of the lesion at or above the bifurcation of the hepatic duct have a major impact on the extent of surgical intervention required and should be reflected in any classification of bile duct injuries.

Abstract
Benign strictures of the biliary ducts are treated surgically in 90% of cases. Usually they are caused by trauma to the choledochous duct during gallbladder operations. Younger patients are frequently affected and, particularly if the strictures go untreated, can suffer from secondary complications such as cholangitis or secondary biliary cirrhosis with the serious dangers of portal hypertension and even hepatic failure and death. Although immediate treatment by end-to-end anastomosis has sometimes been described, this method is reasonable only for smooth cuts to the choledochous duct. Good long-term results have been achieved in 86% of cases with Roux-en-Y hepaticojejunostomy. In general, the best way to avoid complications is the all-important surgical maxim of correct indication for the primary operation. The best course is to limit the decision for surgery to symptomatic gallstones.
