Abstract
Objective: To determine the importance of a critical view of safety (CVS) techniques and Rouviere's sulcus (RS) in laparoscopic cholecystectomy (LC) and its relation to biliary duct injuries (BDIs) and to determine the frequency and the type of RS. Design, Setting, and Participants: A descriptive study was carried out among 76 patients presenting to the surgery department of a tertiary care center in Nepal. The study population included all patients in the age group 16-80 years undergoing LC. Outcome Measures: The main outcome of interest was to calculate the percentage of BDIs along with the frequency and the type of RS. Results: A total of 76 patients were enrolled in the study, out of which 57(75%) were female patients with a male-to-female ratio of 1:3 and a mean age of 45.87 ± 15.33 years. Seventy-one (93.4%) patients were diagnosed with symptomatic gallstone disease. The CVS was achieved in 75 (98.7%) of the cases, whereas in 1 case, the CVS could not be achieved, and in the same patient routine LC was converted into open cholecystectomy owing to the difficult laparoscopic procedure. In 56 (73.7%) cases, RS was first visible to the operating surgeons after port installation, alignment, and adequate traction of the gallbladder; in 20 (26.3%) cases, RS was not originally apparent. Conclusion: According to the findings of this study and the literature's critical assessment of safety, this method will soon become a gold standard for dissecting gall bladder components. The technique needs to be extended further, especially for training purposes. Major difficulties can be avoided by identifying RS before cutting the cystic artery or duct during LC.

Abstract
BACKGROUND Bile duct injury is a serious surgical complication of laparoscopic cholecystectomy. The aim of this study was to identify distinct visual gaze patterns associated with the prompt detection of bile duct injury risk during laparoscopic cholecystectomy. METHODS Twenty-nine participants viewed a laparoscopic cholecystectomy that led to a serious bile duct injury ('BDI video') and an uneventful procedure ('control video') and reported when an error was perceived that could result in bile duct injury. Outcome parameters include fixation sequences on anatomical structures and eye tracking metrics. Surgeons were stratified into two groups based on performance and compared. RESULTS The 'early detector' group displayed reduced common bile duct dwell time in the first half of the BDI video, as well as increased cystic duct dwell time and Calot's triangle glances count during Calot's triangle dissection in the control video. Machine learning based classification of fixation sequences demonstrated clear separability between early and late detector groups. CONCLUSION There are discernible differences in gaze patterns associated with early recognition of impending bile duct injury. The results could be transitioned into real time and used as an intraoperative early warning system and in an educational setting to improve surgical safety and performance.

Abstract
As transanal total mesorectal excision (taTME) becomes increasingly utilized, its technical challenges and potential pitfalls have become more clearly appreciated. This chapter explores the differences in how anatomy presents itself from the taTME vantage point as compared with traditional approaches to taTME, and how special problems unique to taTME pose a new set of operative challenges. Morbidity related, specifically, to the technique of taTME is also delineated with particular focus on male urethral injury.

Abstract
BACKGROUND Transanal total mesorectal excision is a new approach to curative-intent rectal cancer surgery. Training and surgeon experience with this approach has not been assessed previously in America. OBJECTIVE The purpose of this study was to characterize a structured training program and to determine the experience of delegate surgeons. DESIGN Data were assimilated from an anonymous, online survey delivered to attendees on course completion. Data on surgeon performance during hands-on cadaveric dissection were collected prospectively. SETTINGS This study was conducted at a single tertiary colorectal surgery referral center, and cadaveric hands-on training was conducted at a specialized surgeon education center. MAIN OUTCOME MEASURES The main outcome measurement was the use of the course and surgeon experience posttraining. RESULTS During a 12-month period, eight 2-day transanal total mesorectal excision courses were conducted. Eighty-one colorectal surgeons successfully completed the course. During cadaveric dissection, 71% achieved a complete (Quirke 3) specimen; 26% were near complete (Quirke 2), and 3% were incomplete (Quirke 1). A total of 9.1% demonstrated dissection in the incorrect plane, whereas 4.5% created major injury to the rectum or surrounding structures, excluding the prostate. Thirty eight (46.9%) of 81 surgeon delegates responded to an online survey. Of survey respondents, 94.6% believed training should be required before performing transanal total mesorectal excision. Posttraining, 94.3% of surgeon delegates planned to use transanal total mesorectal excision for distal-third rectal cancers, 74.3% for middle-third cancers, and 8.6% for proximal-third cancers. The most significant complication reported was urethral injury; 5 were reported by the subset of survey respondents who had performed this operation postcourse. LIMITATIONS The study was limited by inherent reporting bias, including observer and recall biases. CONCLUSIONS Although this structured training program for transanal total mesorectal excision was found to be useful by the majority of respondents, the risk of iatrogenic injury after training remains high, suggesting that this training pedagogy alone is insufficient.

Abstract
Simulation has been used for medical teaching and testing for at least four decades in some form, such as that used for cardiopulmonary resuscitation training; however, new technology applied to medical and procedural training has recently led to a marked increase in the use of simulation-based instruction. Educational theory has further supported simulation for medical education and procedural training. Simulation-based testing to demonstrate competence with new procedures is already required by the US Food and Drug Administration for one angiographicallyplaced device, and it is likely that simulationbased credentialing for procedures will be increasingly prevalent. Anesthesiologists, like other physicians, may be credentialed or certified based on their performance in a simulated environment in the future. This review describes some of the current simulation-based education techniques related to cardiovascular and thoracic anesthesiology. Additional discussion covers some of the applicable educational theory and the expected future uses of simulation modalities in healthcare education, testing, and practice.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) is a commonly performed surgical procedure; however, it is associated with an increased rate of bile duct injury (BDI) when compared to the open approach. The critical view of safety (CVS) provides a secure method of ductal identification to help avoid BDI. CVS is not universally utilized by practicing surgeons and/or taught to surgical residents. We aimed to pilot a safe cholecystectomy curriculum to demonstrate that educational interventions could improve resident adherence to and recognition of the CVS during LC. METHODS Forty-three general surgery residents at Thomas Jefferson University Hospital were prospectively studied. Fifty-one consecutive LC cases were recorded during the pre-intervention period, while the residents were blinded to the outcome measured (CVS score). As an intervention, a comprehensive lecture on safe cholecystectomy was given to all residents. Fifty consecutive LC cases were recorded post-intervention, while the residents were empowered to "time-out" and document the CVS with a doublet photograph. Two independent surgeons scored the videos and photographs using a 6-point scale. Residents were surveyed pre- and post-intervention to determine objective knowledge and self-reported comfort using a 5-point Likert scale. RESULTS In the 18-week study period, 101 consecutive LCs were adequately captured and included (51 pre-intervention, 50 post-intervention). Patient demographics and clinical data were similar. The mean CVS score improved from 2.3 to 4.3 (p < 0.001). The number of videos with CVS score >4 increased from 15.7 to 52 % (p < 0.001). There was strong inter-observer agreement between reviewers. The pre- and post-intervention questionnaire response rates were 90.7 and 83.7 %, respectively. A greater number of residents correctly identified all criteria of the CVS post-intervention (41-93 %, p < 0.001) and offered appropriate bailout techniques (77-94 %, p < 0.001). Residents strongly agreed that the CVS education should be included in general surgery residency curriculum (mean Likert score = 4.71, SD = 0.54). Residents also agreed that they are more comfortable with their LC skills after the intervention (4.27, σ = 0.83). CONCLUSION The combination of focused education along with intraoperative time-out significantly improved CVS scores and knowledge during LC in our institution.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) has been performed clinically for more than 20 years. However, the incidence of bile duct injury (BDI) remains high despite attempts to prevent and reduce it. The aim of this study was to use an intraoperative unfavorable factors ratings system to identify unfavorable intraoperative factors and evaluate the effectiveness of application of the system in reducing BDI during LC. PATIENTS AND METHODS Between January 2009 and December 2010, 780 patients who underwent LC were reviewed retrospectively, including 384 LC patients without graded treatment of intraoperative unfavorable factors (GTIUF) during 2009 and 396 LC patients with routine GTIUF during 2010. RESULTS BDI was decreased significantly after routine GTIUF (5 cases without GTIUF versus 0 cases with routine GTIUF; P=.029). There was no significant difference in postoperative morbidity and mortality between the two groups. The mean operation duration of the routine GTIUF group was prolonged significantly (P<.0001). Laparoscopic cholecystitis grading, GTIUF, and doctor's experience were important factors affecting the duration of operation (P<.0001, P<.0001, and P<.0001, respectively). CONCLUSIONS GTIUF is an effective method that emphasizes identification of the course of the extrahepatic bile duct and reduces the occurrence of BDI, especially for inexperienced operators.

Abstract
Laparoscopic cholecystectomy, obesity, insurance status, and hospital volume were not associated with an increased risk of bile duct injury. Background and Objectives: Previously, risk factors for bile duct injury have been identified as acute cholecystitis, male gender, older age, aberrant biliary anatomy, and laparoscopic cholecystectomy. Methods: A retrospective analysis of the Nationwide Inpatient Sample from 1998 to 2006 was performed with an inclusion criterion of cholecystectomy performed on hospital day 0 or 1. Patient- and hospital-level factors potentially associated with bile duct injury were examined by logistic regression. Results: A total of 377,424 cholecystectomy patients were identified. There were 1124 bile duct injuries (0.30%), with 177 (0.06%) in the laparoscopic cholecystectomy group and 947 (1.46%) in the open cholecystectomy group (P < .001). On multivariate analysis, significant risk factors for bile duct injury were male gender (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.06–1.38; P = .006), age >60 years (OR, 2.23; 95% CI, 1.61–3.09; P < .001), and academic hospital status (OR, 1.37; 95% CI, 1.05–1.79; P = .02). Acute cholecystitis was associated with a lower risk of bile duct injury (OR, 0.67; 95% CI, 0.46–0.99; P = .044). Conclusion: Independent risk factors for bile duct injury included male gender, age >60 years, and academic hospital status. Laparoscopic cholecystectomy, obesity, insurance status, or hospital volume was not associated with an increased risk of bile duct injury.

Abstract
There is a significant learning curve in acquiring singleincision laparoscopic appendectomy skills in pediatric patients. Introduction: Laparoscopic appendectomy is accepted as the gold standard technique for the treatment of acute appendicitis. Recently single-incision laparoscopic surgery (SILS) was tried in the pediatric population and was shown to be both feasible and safe. We describe our early experience in teaching the SILS procedure for appendicitis in a large community hospital center surgical residency program. Methods: SILS appendectomy was performed in 40 consecutive patients with acute appendicitis who were admitted by a single surgeon from May 2011 to August 2011. All patients over the age of 4 y presenting with noncomplicated and complicated appendicitis (perforated) were offered SILS appendectomy. Execution of the technical aspects of 20 SILS operations done by 3 PGY III residents was evaluated. Results: The average age of the patient was 11.1 y (range, 7 to 15). SILS was performed successfully in 19 out of 20 patients. Nineteen patients underwent emergent or urgent appendectomy, while 1 patient underwent an interval procedure. Nine patients were found to have perforated appendicitis, while the other 11 had noncomplicated acute appendicitis. One patient was converted to conventional 3-port laparoscopy due to difficulties during the procedure. The mean operative time was 73 min (range, 47 to 112). A significant learning curve to successfully execute the critical steps of the SILS procedure was noted in all residents evaluated. Conclusion: SILS technology appears promising for the treatment of acute appendicitis. However, its successful incorporation into surgical training programs will depend on the development of innovative simulation strategies.

Abstract
The use of endoscopic retrograde cholangiopancreatography for treating benign biliary strictures has become the standard of practice, with surgery and percutaneous therapy reserved for selected patients. The gold-standard endoscopic therapy is dilation of the stricture followed by placing and exchanging progressively larger and more numerable plastic stents over a 1-year period. Newer modalities, including the use of fully covered metal stents, are currently under investigation in an effort to improve the treatment of benign biliary strictures.

Abstract
Bile duct injury (BDI) is the most serious iatrogenic complication during laparoscopic cholecystectomy (LC) and occurs easily in inexperienced surgeons since the position of common bile duct (CBD) and its related ductal junctions are hard to precisely identify in the hepatic anatomy during surgery. BDI can be devastating, leading to chronic morbidity, high mortality, and prolonged hospitalization. In addition, it is the most frequent injury resulting in litigation and the most likely injury associated with a successful medical malpractice claim against surgeons. This study introduces a novel method for conveniently and rapidly indicating the anatomical location of CBD during LC by the direct fiber-optic illumination of 532-nm diode-pumped solid state laser through a microstructured plastic optical fiber to avoid the wrong identification of CBD and the injury from mistakenly cutting the CBD that can lead to permanent and even life threatening consequences. Six porcine were used for preliminary intra-CBD illumination experiments via laparotomy and direct duodenal incision to insert the invented CBD illumination laser catheter with nonharmful but satisfactory visual optical density.

Abstract
AbstractIntroduction:Until early 2003, the Consultative Committee on Road Traffic Fatalities (CCRTF) in Victoria, Australia was the main body investigating and publishing data about prehospital errors resulting from road traffic fatalities. The objective of this study was to identify and interpret prehospital error rate trends associated with road traffic fatalities during a 10-year period of the CCRTF reports.Methods:This study is a review of the prehospital errors defined in Victorian CCRTF reports of preventable deaths of road traffic fatalities over a 10-year period.Results:Six CCRTF reports contained prehospital data for errors associated with road traffic fatalities. From 1992 to 1998, system errors decreased.However, over the same timeframe, management, technical, and diagnostic errors increased. There was a marked jump in system, technique, and diagnosis errors from 1998 to 2001–2003. However, management errors declined over the same timeframe. The jump in errors in the 1998 to 2001–2003 timeframe coincided with the introduction of advanced life support (ALS) for Victorian paramedics in 2000.The number of preventable deaths decreased from 1992 to 1998, however, there was an increase from 1999 onwards, coinciding with the introduction of the state trauma system and ALS for paramedics.Conclusions:This study demonstrates that there has been an increase in prehospital error rates, especially from 2000, which coincided with the introduction of ALS for paramedics and the state trauma system in Victoria, even though the state trauma system had an overall decrease in error rates.

Abstract
Laparoscopic cholecystectomy is now one of the most frequently performed abdominal surgical procedures in the world. The most common major complication is bile duct injury, which can have catastrophic repercussions for patients and it has been suggested that intraoperative cholangiography may reduce the rate of bile duct injury. Whether this procedure should be performed routinely is still an active subject of debate. We discuss the available evidence and likely implications for the future.

Abstract
Endoscopic treatment is the mainstay of therapy for benign billiary strictures, and surgery is reserved for selected patients in whom endoscopic treatment fails or is not feasible. The endoscopic approach depends mainly on stricture etiology and location, and generally involves the placement of one or multiple plastic stents, dilation of the stricture(s), or a combination of these approaches. Knowledge of biliary anatomy, endoscopy experience and a well-equipped endoscopy unit are necessary for the success of endoscopic treatment. This Review discusses the etiologies of benign biliary strictures and different endoscopic therapies and their respective outcomes. Data on newer therapies, such as the placement of self-expandable metal stents, and the treatment of biliary-enteric anastomotic strictures is also reviewed.

Abstract
OBJECTIVE To evaluate the prognosis of patients with iatrogenic bile duct injury (IBDI) regarding time of referral (RT) to the unit of liver transplantation (LT). METHODS We reviewed 51 charts of patients who had suffered some kind of IBDI during cholecystectomy and who were referred to the Bonsucesso General Hospital (HGB) LT unit. Lesions were grouped according to the Bismuth classification. Besides cholecystectomy (time of injury), we also evaluated the RT and outcome. RESULTS Among the 51 patients studied, there were 17 men and 34 women, with a mean age of 42.7 years. Twenty-two patients (43.1%) had a type II lesion, 13 (25.5%) type III, 10 (19.6%) type I, 5 (9.8%) type IV and only 1 (2%) type V. Forty patients were operated, and three did not return for medical review, therefore, 37 were evaluated in relation to outcome. Among these, 25 patients (67.6%) had excellent or good results with average RT of 11.5 months (range: 2-48 months) and 47.2 months (range: 3-180 months) respectively. The 12 patients (32.4%) with poor results had a mean RT of 65.9 months (range: 3 264 months), which was significantly higher than the group with excellent or good results (p=0.004). Seven patients were listed for LT, but only two were transplanted. The RT of these seven patients was significantly higher (p=0.04) than those patients not listed. Seven patients died, six of which were due to liver complications. CONCLUSION RT significantly influenced the prognosis of patients in our sample.

Abstract
OBJECTIVE The aim of this study is to analyze surgeon's proficiency, based on the different aspects of his learning curve as a risk factor for iatrogenic biliary tract injuries associated with Laparoscopic Cholecystectomy. METHODS a retrospective study was conducted using the report information from charts of patients January 1992 through December 2007; at Hospital Universitário Clementino Fraga Filho da Universidade Federal do Rio de Janeiro. Analysis from data collected from charts of 2285 patients who had undergone laparoscopic cholecystectomies. Data from surgeons involved with this type of surgery was also analyzed. RESULTS a total of six injuries (0.26%) were found. This result is similar to that found in international publications. All injuries had occurred in the surgeon's second phase of the learning curve with more than 50 video surgeries. CONCLUSION it was conclude that Video surgery Certificate and previous training are not related to biliary tract injuries in this series. Surgeon's age was not a risk factor in this study. There was statistical significance between surgeons' experience and injuries.

Abstract
OBJECTIVE To assess the results of percutaneous transparieto-hepatic dilation of benign biliary stenosis achieved over a period of 5 years. DESIGN A retrospective study to assess the technique, complications and the clinical, analytical and radiology results. PATIENTS Data was gathered on 13 patients diagnosed in our Hospital between the years 2002 and 2006 with benign biliary stenosis and who had been treated using percutaneous dilation. Patients diagnosed with malignant disease and those who had a prosthesis were excluded. Seven of the patients had received a liver transplant. One patient had an endoscopic dilation on two occasions, with the stenosis persisting. RESULTS A clinical and radiological improvement was observed in 60% of the cases, and an analytical improvement in 69% (61% normal). Re-stenosis occurred in 30% of the cases, of which 50% were rescue support using re-dilation. The complications presented (30.7%) were resolved conservatively. No significant differences were observed between the transplanted and the non-transplanted groups. CONCLUSIONS Transparieto-hepatic dilation of benign biliary stenosis is a fairly safe technique and has a high rate of resolution in the medium term, and avoids the use of surgery in 75% of patients. The results need to be confirmed in larger samples.

Abstract
AIM To compare the outcome of endoscopic therapy for postoperative benign bile duct stricture and benign bile duct stricture due to chronic pancreatitis, including long-term prognosis. METHODS The subjects were 20 patients with postoperative benign bile duct stricture and 13 patients with bile duct stricture due to chronic pancreatitis who were 2 years or more after initial therapy. The patients underwent transpapillary drainage with tube exchange every 3 to 6 months until being free from the tube. Successful therapy was defined as a stent-free condition without hepatic disorder. RESULTS Endoscopic therapy was successful in 90% (18/20) of the patients with postoperative bile duct stricture. The stent was removed (stent free) in 100% (20/20) of the patients, but jaundice resolved in only 10% (2/20) of patients while biliary enzymes kept increasing. Restructure occurred in 5% (1/20) of the patients, but after repeat treatment the stent could be removed. In patients with bile duct stricture due to chronic pancreatitis the therapy was successful in only 7.7% (1/13) of the patients; the stent was retained in 92.3% (12/13) of the patients during a long period. Severe acute pancreatitis occurred in 3.0% (1/33) of the patients as an accidental symptom attributable to endoscopic retrograde cholangiopancreatography (ERCP); however, it remitted after conservative treatment. CONCLUSION Our results further confirm the usefulness of endoscopic therapy for postoperative benign bile duct strictures and good long-term prognosis of the patients.

Abstract
BACKGROUND When laparoscopic cholecystectomy (LC) is performed successfully, recovery is faster than after open cholecystectomy. However, LC results in higher incidences of biliary, bowel and vascular injury. METHODS We performed a retrospective review of LC-related claims reported to the National Health Service Litigation Authority (NHSLA) during 2000-2005. The data were analysed from a medicolegal perspective to assess the effects of type of injury and delay in recognition on litigation costs. RESULTS A total of 208 claims following laparoscopic procedures in general surgery were reported to NHSLA during 2000-2005, of which 133 (64%) were related to LC. Bile duct injury (BDI) accounted for the majority of claims (72%); bowel injury and 'others' accounted for 9% and 19%, respectively. Only 20% of BDIs were recognized during surgery; the majority were missed and diagnosed later. Claims related to LC resulted in payments totalling 6 m pound sterling, of which 4.3 m pound sterling was paid out for BDIs. The average cost was higher for patients who suffered a delay in diagnosis, as was the chance of a successful claim. CONCLUSIONS Bile duct injury incurred during LC remains a serious hazard for patients. The resulting complications have led to litigation that has caused a huge financial drain on the health care system. Delayed recognition appears to correlate with more costly litigation.

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
Several conditions may cause benign biliary stricture formation. Intraoperative bile duct injury, most often sustained during laparoscopic cholecystectomy, is the leading cause. Although surgical bypass procedure was the traditional treatment of choice for benign extrahepatic biliary strictures, therapeutic endoscopic retrograde cholangiopancreatography has recently come into favor; however, success rates have been variable and largely dependent on the underlying etiology. Because endoscopic therapy may be unsuccessful, a multidisciplinary approach to management, with surgical or radiological intervention if necessary, should be considered.

Abstract
BACKGROUND Biliary injuries during laparoscopic cholecystectomy (LC) are complications better avoided than treated. These injuries cause long-lasting morbidity and can be fatal. The authors present their experience with biliary injury in LC during a period exceeding 13 years. METHODS Between January 1992 and December 2005, 13,305 LCs were performed at the authors' institution. The biliary injuries in these cases were recorded and analyzed retrospectively. RESULTS A total of 52 biliary injuries were identified in 13,305 LCs, for an overall incidence of 0.39%. Of these, 32 (0.24%) were diagnosed intraoperatively and 20 (0.15%) were diagnosed postoperatively. The perioperative bile duct injuries (BDIs) included 6 complete transections (5 treated by hepaticojejunostomy and 1 by primary T-tube repair (TTR), all performed by conversion to open procedure), 11 lateral BDIs (2 treated by laparoscopic choledochojejunostomy [CJ], 1 by open CJ, 5 by laparoscopic TTR, 1 by open TTR, and 2 by primary suture repair, both performed laparoscopically), 11 duct of Luschka injuries, and 4 sectoral duct injuries. The BDIs detected postoperatively included 6 patients with bilioma (treated with ultrasonography-guided aspiration), 4 patients with biliary peritonitis (requiring relaparoscopy and peritoneal lavage and drainage followed by endoscopic retrograde cholangiography [ERC] and biliary stenting), and 10 patients with persistent biliary leak-controlled biliary fistula (requiring ERC and stenting). There was no mortality related to BDI in the series. Patients with Strasberg type A/C/D injuries (46 cases) were followed 3 months to 3 years with no major complaints. Two patients with complete transection were lost to follow-up evaluation, whereas the other four patients, followed 18 months to 3 years, were asymptomatic. CONCLUSIONS According to the findings, LC is a safe procedure with an incidence of biliary injury comparable with that for open cholecystectomy. Single-center studies such as this are important to ensure that standards of surgery are maintained in the community.

Abstract
Benign biliary strictures are being increasingly treated with endoscopic techniques. The benign nature of the stricture should be first confirmed in order to ensure appropriate therapy. Surgery has been the traditional treatment, but there is increasing desire for minimally invasive endoscopic therapy. At present, endoscopy has become the first line approach for the therapy of post-liver transplant anastomotic strictures and distal (Bismuth Iand II) post-operative strictures. Strictures related to chronic pancreatitis have proven more difficult to treat, and endoscopic therapy is reserved for patients who are not surgical candidates. The preferred endoscopic approach is aggressive treatment with gradual dilation of the stricture and insertion of multiple plastic stents. The use of uncovered self expandable metal stents should be discouraged due to poor long-term results. Treatment with covered metal stents or bioabsorbable stents warrants further evaluation. This area of therapeutic endoscopy provides an ongoing opportunity for fresh research and innovation.

Abstract
BACKGROUND/PURPOSE Patient safety is an important issue in medical quality control. To our knowledge, no studies have been conducted to specifically address patient safety in surgery in Taiwan. The purposes of this study were to determine the incidence of surgical errors in Taiwan, to evaluate the effectiveness of a campaign to mark the planned operation site, and the factors that influence the frequency of this preoperative safety maneuver. METHODS In March 2004, each member of the Taiwan Orthopaedic Association was given a 12-question survey regarding wrong-site, wrong-patient, and wrong-procedure errors to provide baseline data. We then implemented a campaign to encourage orthopedic surgeons to mark the planned operation site ("Mark op site" campaign). A follow-up survey was done in October 2004, and the results of both surveys were compared. RESULTS On the second survey, the number of surgeons who marked the incision site had significantly increased (p < 0.05), and the incidences of reported wrong-site (0.5%) and wrong-procedure errors (2.4%) were lower than on the first survey (4.8%, p < 0.05 and 5.6%, p < 0.05). On the second survey, preoperative marking of the incision site was significantly correlated with the location of the surgeon's practice. CONCLUSION Orthopedic surgeons marked the incision sites more frequently after our campaign than before, suggesting that the campaign was effective in changing their behavior. In Taiwan, this campaign reduced the risk of wrong-site and wrong-procedure errors.

Abstract
BACKGROUND/PURPOSE The management of recurrent bile duct strictures is a challenge for surgeons. This study reports the experience of revision surgery in patients referred following the failure of primary repair, and compares the outcome with that in patients who underwent management of recurrent stricture following primary repair at our institution. METHODS Over a period of 15 years, 300 patients with postcholecystectomy benign biliary stricture underwent surgical repair at our institution; 36 patients (12%) were referred after a failed primary repair. RESULTS In 25 (69%) patients, the primary repairs were done at peripheral hospitals. Twelve (33%) had had an early repair, at the time of cholecystectomy while 24 (67%) had a delayed repair at a later date; 83% and 67% of the patients who had undergone early and delayed repair, respectively, had not had a preoperative cholangiogram. Primary repairs performed were a bilioenteric anastomosis (22; 61%) or an end-to-end bile duct repair (14; 39%). Twenty-seven (75%) patients presented within 90 days after the primary repair, and the median interval to recurrent symptoms was 45 days (range, 1 day to 6.1 years). The median delay in referral after the development of symptoms of restricture was 175 days (range, 30 days to 22 years). Twenty-three (64%) patients had high strictures (Bismuth types III-V). All patients underwent a Roux-en-Y hepaticojejunostomy. At a median follow-up of 37 months (range, 12-144 months), 33 of 35 evaluable patients (94%) with recurrent stricture had an excellent/good outcome compared to 223 of 242 evaluable patients (92%) who had had their primary repair at our institution. Ten (4%) patients had a poor result following primary repair at our center. There was a significant difference in the stricture repair-to-recurrence interval between those patients referred to us with recurrent strictures and those who failed after primary repair at our institution (median interval, 1.5 vs 20 months; P = 0.001) CONCLUSIONS Patients referred with recurrent strictures had had their primary repair at peripheral settings; the failures were technical, presenting early (median, 1.5 months) with recurrent symptoms, compared to findings in patients with recurrent strictures following primary repair at our center. The long-term outcome following the repair of the primary and the recurrent strictures was no different in our experience.

Abstract
BACKGROUND Laparoscopic cholecystectomy has a higher incidence of bile-duct injuries than open cholecystectomy. Although a learning curve phenomenon was attributed to biliary injuries early after its introduction, we were interested in trends in biliary injury rates over time as laparoscopic cholecystectomy has become a mature technology. OBJECTIVE To analyze the frequency and anatomic distribution of bile-duct injuries referred after laparoscopic cholecystectomy over a 10-year period. DESIGN Retrospective, case-series. SETTING Tertiary, referral hepatobiliary unit. PATIENTS Referrals to ERCP unit for diagnosis and treatment of biliary injuries after laparoscopic cholecystectomy. INTERVENTION ERCP to diagnose level and severity of bile duct injury. MAIN OUTCOME MEASUREMENTS Type and anatomy of bile-duct injury, reason for cholecystectomy, mean time between injury and diagnosis, presenting symptoms, ratio of bile-duct injuries diagnosed over total ERCPs done per year. RESULTS There were 87 bile-duct leaks, 28 leaks with stones, 51 strictures, and 17 complete duct transactions. The bile-duct injury rate calculated per 100 ERCPs per year was 0.84 (1994), 0.99 (1995), 1.36 (1996), 1.41 (1997), 1.03 (1998), 1.31 (1999), 0.84 (2000), 0.75 (2001), 1.15 (2002), and 0.94 (2003). LIMITATIONS Single institution, retrospective analysis, unknown denominator of cholecystectomies done in referral area per year to calculate true bile-duct injury rate. CONCLUSIONS Static incidence in frequency, anatomic distribution, and rate per 100 ERCPs per year of postcholecystectomy bile-duct injuries at a tertiary referral hepatobiliary unit over a 10-year period of observation.

Abstract
OBJECTIVES Surgical simulation has been shown to enhance the training of general surgery residents. Since catheter-based techniques have become an important part of the vascular surgeon's armamentarium, we explored whether simulation might impact the acquisition of catheter skills by surgical residents. METHODS Twenty general surgery residents received didactic training in the techniques of catheter intervention. Residents were then randomized with 10 receiving additional training with the Procedicus, computer-based, haptic simulator. All 20 residents then participated in 2 consecutive mentored catheter-based interventions for lower extremity occlusive disease in an OR/angiography suite. Resident performance was graded by attending surgeons blinded to the resident's training status, using 18 procedural steps as well as a global rating scale. RESULTS There were no differences between the 2 resident groups with regard to demographics or scores on a visuospatial test administered at study outset. Overall, residents exposed to simulation scored higher than controls during the first angio/OR intervention: procedural steps (simulation/control) (50 +/- 6 vs. 33 +/- 9, P = 0.0015); global rating scale (30 +/- 7 vs. 19 +/- 5, P = 0.0052). The advantage provided by simulator training persisted with the second intervention (53 +/- 6 vs. 36 +/- 7, P = 0.0006); global rating scale (33 +/- 6 vs. 21 +/- 6, P = 0.0015). Moreover, simulation training, particularly for the second intervention, led to enhancement in almost all of the individual measures of performance. CONCLUSION Simulation is a valid tool for instructing surgical residents and fellows in basic endovascular techniques and should be incorporated into surgical training programs. Moreover, simulators may also benefit the large number of vascular surgeons who seek retraining in catheter-based intervention.

This study sought to determine whether the unique autofluorescent properties of bile could facilitate intraoperative identification of the biliary anatomy in mice using fluorescent cholangiography. METHODS Fluorimetry was performed on samples of mouse bile to determine excitation and emission spectra. For seven mice, chevron laparotomy was performed, followed by liver retraction to expose the porta hepatis. Using stereomicroscopy, photographs were taken in brightfield and fluorescent modes without a change in depth or focus. Six surgical residents evaluated the pictures and identified the gallbladder, cystic duct, common bile duct, and whether the cystic duct joined the right hepatic duct or the common bile duct. RESULTS Fluorimetry demonstrated autofluorescence of bile at an excitation wavelength of 475 nm. Intense emission was observed at 480 nm. At these settings, fluorescent stereomicroscopy easily identified the gallbladder and biliary tree in mice. This technique decreased diagnostic errors of the biliary anatomy 11-fold (2% vs 22%; p < 0.01), as compared with brightfield visualization. Fluorescent stereomicroscopy also was used to diagnose bile leak, obstruction, and complex anatomy. Using a prototype 5-mm laparoscope equipped with fluorescent filters, the results were reproduced. CONCLUSIONS Fluorescent cholangiography based solely on the autofluorescence of bile may facilitate real-time identification of the biliary anatomy during laparoscopic procedures, without the need for extraneous dye administration or the use of radiography. This technique has the potential to decrease the rate of iatrogenic biliary tract injuries during laparoscopic cholecystectomy.

Abstract
OBJETIVO: O objetivo do presente estudo foi avaliar os casos de lesões iatrogênicas de vias biliares tratados na clínica cirúrgica do Hospital Getúlio Vargas - HGV nos últimos oito anos. MÉTODO: Foi realizada análise retrospectiva dos prontuários dos pacientes internados no HGV, com hipótese diagnóstica de lesão iatrogênica de vias biliares. Foram incluídos pacientes com lesões provenientes do próprio serviço e de outras instituições. Os prontuários foram revisados e obtidas as seguintes variáveis: procedência do paciente, idade, sexo, data da cirurgia inicial, sintomas, tempo de evolução, valores da bilirrubina, fosfatase alcalina, AST e ALT, TAP, creatinina, além da cirurgia realizada para correção da lesão, complicações, permanência hospitalar e condições do paciente na alta hospitalar. RESULTADOS: Foram confirmados 10 casos de lesão iatrogênica de vias biliares. Todos os paciente eram do sexo feminino, com idades variando entre 18 e 49 anos. Os sinais ou sintomas mais freqüentes foram icterícia, colúria e dor abdominal. Em relação à terapêutica cirúrgica, a hepático-jejunostomia em "Y" de Roux foi o procedimento mais empregado. CONCLUSÕES: As lesões iatrogênicas das vias biliares ainda representam um desafio para os cirurgiões e sua ocorrência está mais relacionada a procedimentos realizados em hospitais não especializados, por cirurgiões sem treinamento adequado. A principal medida a ser adotada é a prevenção da lesão. Após sua ocorrência, esta deve ser corrigida em hospitais com equipe médica treinada.

Abstract
INTRODUCTION Computer simulation has been used in a variety of training programs, ranging from airline piloting to general surgery. In this study we evaluate the use of simulation to train novice and advanced interventionalists in catheter-based techniques. METHODS Twenty-one physicians underwent evaluation in a simulator training program that involved placement of a carotid stent. Five participants were highly experienced in catheter-based techniques (>300 percutaneous cases), including carotid angioplasty and stenting (CAS); the remaining 16 participants were interventional novices (<5 percutaneous cases). The Procedicus VIST simulator, composed of real-time vascular imaging simulation software and a tactile interface coupled to angiographic catheters and guide wires, was used. After didactic instruction regarding CAS and use of the simulator, each participant performed a simulated CAS procedure. The participant's performance was supervised and evaluated by an expert interventionalist on the basis of 50 specific procedural steps with a maximal score of 100. Specific techniques of guide wire and catheter manipulation were subjectively assessed on a scale of 0 to 5 points based on ability. After evaluation of the initial simulated CAS procedure, each participant received a minimum of 2 hours of individualized training by the expert interventionalist, with the VIST simulator. Each participant then performed a second simulated CAS procedure, which was graded with the same scale. After completion, participants assessed the training program and its utility via survey questionnaire. RESULTS The average simulated score for novice participants after the training program improved significantly from 17.8 +/- 15.6 to 69.8 +/- 9.8 (P < .01), time to complete simulation decreased from 44 +/- 10 minutes to 30 +/- 8 minutes (P < .01), and fluoroscopy time decreased from 31 +/- 7 minutes to 23 +/- 7 minutes ( P < .01). No statistically significant difference in score, total time, or fluoroscopy time was noted for experienced interventionalists. Improvement was noted in guide wire and catheter manipulation skills in novices. Analysis of survey data from experienced interventionalists indicated that the simulated clinical scenarios were realistic and that the simulator could be a valuable tool if clinical and tactile feedback were improved. Novices also thought the simulated training was a valuable experience, and desired further training time. CONCLUSIONS An endovascular training program using the Procedicus VIST haptic simulator resulted in significant improvement in trainee facility with catheter-based techniques in a simulated clinical setting. Novice participants derived the greatest benefit from simulator training in a mentored program, whereas experienced interventionalists did not seem to derive significant benefit.

Abstract
BACKGROUND The 1990s were associated with a dramatic increase in bile duct injuries with the widespread use of laparoscopic cholecystectomy (LC). Interventional radiology has an integral role in diagnosing and managing these injuries. Definitive percutaneous management with balloon dilatation might be possible in select patients with intact biliary-enteric continuity, but longterm data are limited. STUDY DESIGN Data were collected prospectively on 51 consecutive patients with major bile duct stricture or injury associated with LC, treated with percutaneous management, January 1, 1990, to December 31, 1999. Percutaneous transhepatic cholangiography and biliary catheter placement were followed by balloon dilatation and stenting. Outcomes were assessed with direct patient contact or hospital records. RESULTS All patients completed treatment, and 50 (98%) were stent free at mean followup of 76 months. The success rate of percutaneous management was 58.8%, without need for subsequent intervention. Presenting symptoms, level of injury, and number of stents or dilatations did not predict outcomes. Percutaneous treatment was more likely to fail in patients stented for less than 4 months (p < 0.001). Operative repair at Hopkins before percutaneous management was predictive of a successful outcome (p < 0.05). Including subsequent operations or percutaneous management, successful outcomes were achieved in 98% of patients. CONCLUSIONS Major bile duct injuries after LC remain a clinical challenge. Although surgical reconstruction is the treatment cornerstone, selected patients with biliary-enteric continuity can achieve successful long-term results with definitive percutaneous management. The combination of percutaneous management and surgical reconstruction results in successful outcomes in virtually all patients.

Abstract
BACKGROUND Bile duct injuries (BDIs) during laparoscopic cholecystectomy (LC) still are reported with greater frequency than during open cholecystectomy (OC). METHODS In 1999, a retrospective study evaluating the incidence of BDIs during LC in the area of Rome from 1994 to 1998 (group A) was performed. In addition, a prospective audit was started, ending in December 2001 (group B). RESULTS In group A, 6,419 LCs were performed (222 were converted to OC; 3.4%). In group B, 7,299 LCs were performed (225 were converted to OC; 3.1%). Seventeen BDIs (0.26%) occurred in group A and 16 (0.22%) in group B. Overall, mortality and major morbidity rates were 12.1% and 30.3%, respectively, without significant differences between the two groups. CONCLUSIONS The incidence and clinical relevance of BDIs during LC in the area of Rome appeared to be stable over the past 8 years and were not influenced by the use of a prospective audit, as compared with a retrospective survey.

Abstract
BACKGROUND Bile duct injuries remain one of the most devastating injuries during laparoscopic cholecystectomy. Few studies target surgeons who have experienced bile duct injuries for their insight, their perspective, and their suggestions concerning this problem. METHODS A confidential questionnaire was sent to all practicing general surgeons under the age of 65 years in British Columbia, Canada. RESULTS Seventy-five percent of surgeons responded to the survey. Of the 114 questionnaires completed, more than 97% of respondents had completed formal training in laparoscopic cholecystectomy. One half of surgeons reported experience with laparoscopic bile duct injury. A significant difference in years in practice between surgeons with injury and surgeons without injury was noted. The majority of injuries occurred after the surgeons's first 100 cholecystectomies performed. The first thoughts of surgeons after injury uniformly concerned the patient's well being. The next most common thoughts were in relation to obtaining help or a second opinion from another surgeon. Surgeons cited inflammation and short or anomalous cystic ducts as the most responsible factors contributing to injury. The majority of surgeons felt that these injuries are unavoidable and less than half felt that it was always a surgical error. Fewer than 15% thought injuries could be avoided by performing a cholangiogram. Surgeons suggested meticulous dissection and less haste to divide structures may prevent an injury. Surgeons recommend educating colleagues to remove the stigma of failure associated with conversion to laparotomy. CONCLUSIONS General surgeons in British Columbia have a one in two chance of experiencing a bile duct injury in their career. There were more injuries in surgeons who had already been in practice for 10 years at the time of introduction of laparoscopic cholecystectomy. The injuries are likely to occur despite high volumes of procedures and increased experience. The incidence of bile duct injuries does not seem to be different in surgeons who perform routine cholangiography and most surgeons feel that cholangiography would have little effect on injury incidence. Surgeons tend to have patient-centered concerns after injury and little concern for medicolegal issues. The majority of surgeons felt that these injuries could not be anticipated and as such it is an inherent risk of this procedure.

Abstract
INTRODUCTION Injuries to the extrahepatic biliary tree at laparoscopic cholecystectomy cause major morbidity and are a major source of litigation. Injuries are often diagnosed late, leading to further complications and decreasing the chance of a successful repair. METHODS A prospective study was carried out of all patients with extrahepatic biliary injuries from cholecystectomy who were referred to the surgeons of the Universities of Melbourne Hepatobiliary Group between 1997 and 1999. RESULTS Twenty-seven patients sustained biliary injuries to the extrahepatic biliary tree. Twenty patients (74%) had unrecognized injuries at the time of cholecystectomy. The median time to referral was 9 days. Only two of 11 operative cholangiograms were interpreted as showing a biliary injury. CONCLUSION Biliary injuries are still occurring at laparoscopic cholecystectomy. Guidelines about the management of a suspected biliary injury are discussed. Clinical, radiological and pathological assessment should enable prompt diagnosis and management should be instituted early, preferably with the involvement of a hepatobiliary specialist.

Abstract
BACKGROUND Hospitals with one or only a few practicing surgeons need a valid way to analyze the quality of their work. Head-to-head comparisons, especially in a competitive small environment, are not likely to be fruitful. METHODS We compared the quality of surgical care delivered by a single surgeon whose practice was located in rural Kentucky with that of a group of peers in the same region. A surgical data sheet was completed by each of the participating surgeons from July 1, 1998, to September 1, 2001. The cases were entered into a database maintained by a professional limited liability corporation, which was founded to enhance the quality of surgical care. We measured quality of care based on complication rate, patient education, resource utilization, use of diagnostic testing, and number of days the patient returned to work. RESULTS A total of 11,761 cases were entered into the database during the 38 months recorded. Of those, 256 cases were performed by the studied surgeon. The cases included skin and subcutaneous biopsies (n = 145), colonoscopies (n = 80), upper endoscopies (n = 25), and inguinal hernia repair (n = 6). The studied surgeon performed better than the peer group in the categories of patient education, complication rates, and use of diagnostics. Resource utilization, as measured by length of stay, was identified as an area that could be improved. CONCLUSIONS By using this organization and its methods, a good way to identify strengths and weaknesses of delivered surgical care is enabled.

Abstract
OBJECTIVE To assess the quality of life (QOL) of patients after surgical reconstruction of a major bile duct injury from laparoscopic cholecystectomy (LC). SUMMARY BACKGROUND DATA The incidence of bile duct injuries has increased dramatically since the introduction and widespread use of LC. Previous reports show that at long-term follow-up, most patients surgically repaired will have a successful outcome as measured by standard clinical parameters. However, there is a general impression that these patients have an impaired QOL. Data addressing QOL of these patients are limited. METHODS A standard QOL questionnaire was sent to 89 patients after successful surgical repair of a major bile duct injury from a LC treated at the Johns Hopkins Hospital between 1990 and 2000. The instrument consisted of 30 items on a visual analog scale categorized into physical (15 items), psychological (10 items), and social (5 items) domains. The same questionnaire was sent to age- and sex-matched healthy controls (n = 100) and to patients who underwent uncomplicated LC (n = 100). An additional portion of the questionnaire inquired about outcome measures and legal action undertaken by patients. RESULTS Overall QOL scores for bile duct injury patients in the three domains (physical, psychological, and social) were 76%, 77%, and 75%, respectively. QOL scores were comparable to those of patients undergoing uncomplicated LC and healthy controls in the physical and social domains but were significantly different in the psychological domain. Presenting symptoms, prior repair, level of injury, number of stents, length of postoperative stenting, and length of follow-up did not influence QOL scores. Repaired patients reported similar rates of abdominal pain, change in bowel habits, use of pain medications, and recent symptoms of fever or chills as LC controls. Thirty-one percent of responding bile duct injury patients reported having sought legal recourse for their injury. All QOL domain scores were significantly lower in the patients who pursued a lawsuit versus those who did not. CONCLUSIONS This study provides formal data evaluating QOL after surgical repair of major bile duct injuries from LC. Although there was a significant difference in the QOL as evaluated from a psychological dimension, bile duct injury patients reported QOL scores in the physical and social domains comparable to those of control patients. The decreased QOL assessment in the psychological dimension may be attributable to the prolonged, complicated, and unexpected nature of these injuries. The presence of a lawsuit appears to be associated with a poorer QOL assessment.

Abstract
BACKGROUND Laparoscopic cholecystectomy (LC) has become the first-line surgical treatment of calculous gall-bladder disease and the benefits over open cholecystectomy are well known. In the early years of LC, the higher rate of bile duct injuries compared with open cholecystectomy was believed to be due to the 'learning curve' and would dissipate with increased experience. The purpose of the present paper was to review a tertiary referral unit's experience of bile duct injuries induced by LC. METHODS A retrospective analysis was performed on all patients referred for management of an iatrogenic bile duct injury from 1981 to 2000. For injuries sustained at LC, details of time between LC and recognition of the injury, time from injury to definitive repair, type of injury, use of intraoperative cholangiography (IOC), definitive repair and postoperative outcome were recorded. The type of injury sustained at open cholecystectomy was similarly classified to allow the severity of injury to be compared. RESULTS There were 131 patients referred for management of an iatrogenic bile duct injury that occurred at open cholecystectomy (n = 62), liver resection (n = 5) and at LC (n = 64). Only 39% of bile duct injuries were recognized at the time of LC. Following conversion to open operation, half the subsequent procedures were considered inappropriate. When the injury was not recognized during LC, 70% of patients developed bile leak/peritonitis, almost half of whom were referred, whereas the rest underwent a variety of operative procedures by the referring surgeon. The remainder developed jaundice or abnormal liver function tests and cholangitis. An IOC was performed in 43% of cases, but failed to identify an injury in two-thirds of patients. The bile duct injuries that occurred at LC were of greater severity than with open cholecystectomy. Following definitive repair, there was one death (1.6%). Ninety-two per cent of patients had an uncomplicated recovery and there was one late stricture requiring surgical revision. CONCLUSIONS The early prediction that the rate of injury during LC would decline substantially with increased experience has not been fulfilled. Bile duct injury that occurs at LC is of greater severity than with open cholecystectomy. Bile duct injury is recognized during LC in less than half the cases. Evidence is accruing that the use of cholangiography reduces the risk and severity of injury and, when correctly interpreted, increases the chance of recognition of bile duct injury during the procedure. Prevention is the key but, should an injury occur, referral to a specialist in biliary reconstructive surgery is indicated.

Abstract
OBJECTIVE To determine whether surgical residency training has influenced the occurrence of common bile duct injuries during laparoscopic cholecystectomy, and to asses the anatomic and technical details of bile duct injuries from the practices of surgeons trained in laparoscopic cholecystectomy after residency versus surgeons trained in laparoscopic cholecystectomy during residency. SUMMARY BACKGROUND DATA Shortly after the introduction of laparoscopic cholecystectomy, the rate of injury to the common bile duct increased to 0.5%, and injuries were more commonly reported early in each surgeon's experience. It is not known whether learning laparoscopic cholecystectomy during surgery residency influences this pattern. METHODS An anonymous questionnaire was mailed to 3,657 surgeons across the United States who completed an Accreditation Council for Graduate Medical Education (ACGME)-approved residency between 1980 and 1990 (group A) or 1992 and 1998 (group B). All surgeons in group A learned laparoscopic cholecystectomy after residency, and all those in group B learned laparoscopic cholecystectomy during residency. Information obtained included practice description, number of laparoscopic cholecystectomies completed since residency, postgraduate training in laparoscopy, and annual volume of laparoscopic cholecystectomy in the surgeon's hospital. In addition, technical details queried included the completion of a cholangiogram, the interval between injury and identification, the method of repair, and the site of definitive treatment. The primary endpoint was the occurrence of a major bile duct injury during laparoscopic cholecystectomy (bile leaks without a major bile duct injury were not tabulated). RESULTS Forty-five percent (n = 1,661) of the questionnaires were completed and returned. Mean practice experience was 13.6 years for group A and 5.4 years for group B. At least one injury occurrence was reported by 422 surgeons (37.6%) in group A and 143 surgeons (26.5%) in group B. Forty percent of the injuries in group A occurred during the first 50 cases compared with 22% in group B. Thirty percent of bile duct injuries in group A and 32.9% of all injuries in group B occurred after a surgeon had performed more than 200 laparoscopic cholecystectomies. Independent of the number of laparoscopic cholecystectomies completed since residency, group A surgeons were 39% more likely to report one or more biliary injuries and 58% more likely to report two or more injuries than their counterparts in group B. Bile duct injuries were more likely to be discovered during surgery if a cholangiogram was completed than if cholangiography was omitted (80.9% vs. 45.1%). Sixty-four percent of all major bile duct injuries required biliary reconstruction, and most injuries were definitively treated at the hospital where the injury occurred. Only 14.7% of injuries were referred to another center for repair. CONCLUSIONS Accepting that the survey bias underestimates the true frequency of bile duct injuries, residency training decreases the likelihood of injuring a bile duct, but only by decreasing the frequency of early "learning curve" injuries. If one accepts a liberal definition of the learning curve (200 cases), it appears that at least one third of injuries are not related to inexperience but may reflect fundamental errors in the technique of laparoscopic cholecystectomy as practiced by a broad population of surgeons in the United States. Intraoperative cholangiography is helpful for intraoperative discovery of injuries when they occur. Most injuries are repaired in the hospital where they occur and are not universally referred to tertiary care centers.

Abstract
Benign bile duct strictures are usually iatrogenic and result from surgery near the porta hepatis. If a bile duct injury is suspected intraoperatively, cholangiography is essential, and a careful Roux-en-Y biliary-enteric anastomosis is often required to achieve the best postoperative result. Alternatively, the patient may be transferred to a tertiary referral center for further management by dedicated biliary surgeons, endoscopists, and radiologists. If transfer is contemplated, a catheter should be passed surgically into the bile duct for postoperative cholangiography with a second drain located alongside the injured bile duct to prevent bilious peritonitis. Benign strictures recognized in the office setting require operative intervention and should be thoroughly investigated by cholangiography and cross-sectional imaging to define the lesion and exclude malignancy. Because indwelling catheters help the surgeon to identify the injured bile duct, we favor the combination of percutaneous transhepatic cholangiography and CT scan or magnetic resonance imaging during the preoperative evaluation. The stenotic bile duct should be resected to exclude malignancy, after which an end-to-side biliary-enteric anastomosis is created by the Roux-en-Y technique. Balloon dilation and percutaneous stent placement are acceptable alternatives to surgical therapy in patients with significant medical comorbidities and may be used successfully as primary therapy for postoperative anastomotic strictures.

Abstract
BACKGROUND AND PURPOSE Laparoscopic cholecystectomy (LC) is the primary treatment of gallstone disease. Although refinements have made it safer, bile duct injury remains more common than with the open approach. The major difference in these techniques is that open cholecystectomy approaches the gallbladder from the fundus downward, whereas conventional laparoscopic cholecystectomy proceeds in the reverse direction. A handful of fundus-down techniques appear in the literature. The use of special instruments or port sites is common. We present a technique that is safe and utilizes instruments familiar to the surgeon performing conventional LC. PATIENTS AND METHODS Fifty consecutive LCs were included in the study. The variables monitored were age, comorbidities, postoperative diagnosis, pathologic diagnosis, length of operation, hospital length of stay, and complications. RESULTS The average operating time for chronic cholecystitis was 1 hour, and the average time for acute cholecystitis was less than 2 hours. Except for one early case of bleeding, in which the procedure was completed using the familiar conventional method, no complications and no unusual technical difficulties were encountered. There were no differences between conventional and fundus-down LC with regard to time and complications. CONCLUSIONS This technique is safe and has several benefits: (1) standard trocar sites that offer the surgeon flexibility in the approach; (2) the ability to resect as much cystic duct as desired; and (3) utilization of standard instruments familiar to the surgeon, thus avoiding costly special instruments. The approach may offer the benefit of reducing the rate of common bile duct injury to that of open cholecystectomy.

Abstract
OBJECTIVE To describe the management and outcome after surgical reconstruction of 156 patients with postoperative bile duct strictures managed in the 1990s. SUMMARY BACKGROUND DATA The management of postoperative bile duct strictures and major bile duct injuries remains a challenge for even the most skilled biliary tract surgeon. The 1990s saw a dramatic increase in the incidence of bile duct strictures and injuries from the introduction and widespread use of laparoscopic cholecystectomy. Although the management of these injuries and short-term outcome have been reported, long-term follow-up is limited. METHODS Data were collected prospectively on 156 patients treated at the Johns Hopkins Hospital with major bile duct injuries or postoperative bile duct strictures between January 1990 and December 1999. With the exception of bile duct injuries discovered and repaired during surgery, all patients underwent preoperative percutaneous transhepatic cholangiography and placement of transhepatic biliary catheters before surgical repair. Follow-up was conducted by medical record review or telephone interview during January 2000. RESULTS Of the 156 patients undergoing surgical reconstruction, 142 had completed treatment with a mean follow-up of 57.5 months. Two patients died of reasons unrelated to biliary tract disease before the completion of treatment. Twelve patients (7.9%) had not completed treatment and still had biliary stents in place at the time of this report. Of patients who had completed treatment, 90. 8% were considered to have a successful outcome without the need for follow-up invasive, diagnos tic, or therapeutic interventional procedures. Patients with reconstruction after injury or stricture after laparoscopic cholecystectomy had a better overall outcome than patients whose postoperative stricture developed after other types of surgery. Presenting symptoms, number of stents, interval to referral, prior repair, and length of postoperative stenting were not significant predictors of outcome. Overall, a successful outcome, without the need for biliary stents, was obtained in 98% of patients, including those requiring a secondary procedure for recurrent stricture. CONCLUSIONS Major bile duct injuries and postoperative bile duct strictures remain a considerable surgical challenge. Management with preoperative cholangiography to delineate the anatomy and placement of percutaneous biliary catheters, followed by surgical reconstruction with a Roux-en-Y hepaticojejunostomy, is associated with a successful outcome in up to 98% of patients.
