BILE DUCT INJURY REPAIR IN A PATIENT WITH SITUS INVERSUS TOTALIS.

BACKGROUND: Bile duct injury (BDI) causes significant sequelae for the patient in terms of morbidity, mortality, and long-term quality of life, and should be managed in centers with expertise. Anatomical variants may contribute to a higher risk of BDI during cholecystectomy. AIMS: To report a case of bile duct injury in a patient with situs inversus totalis. METHODS: A 42-year-old female patient with a previous history of situs inversus totalis and a BDI was initially operated on simultaneously to the lesion ten years ago by a non-specialized surgeon. She was referred to a specialized center due to recurrent episodes of cholangitis and a cholestatic laboratory pattern. Cholangioresonance revealed a severe anastomotic stricture. Due to her young age and recurrent cholangitis, she was submitted to a redo hepaticojejunostomy with the Hepp-Couinaud technique. To the best of our knowledge, this is the first report of BDI repair in a patient with situs inversus totalis. RESULTS: The previous hepaticojejunostomy was undone and remade with the Hepp-Couinaud technique high in the hilar plate with a wide opening in the hepatic confluence of the bile ducts towards the left hepatic duct. The previous Roux limb was maintained. Postoperative recovery was uneventful, the drain was removed on the seventh post-operative day, and the patient is now asymptomatic, with normal bilirubin and canalicular enzymes, and no further episodes of cholestasis or cholangitis. CONCLUSIONS: Anatomical variants may increase the difficulty of both cholecystectomy and BDI repair. BDI repair should be performed in a specialized center by formal hepato-pancreato-biliary surgeons to assure a safe perioperative management and a good long-term outcome.

RESUMO RACIONAL: As lesões de via biliar (LVB) impõem sequelas significativas ao paciente em termos de morbidade, mortalidade e qualidade de vida a longo prazo, devendo ser manejadas em centros especializados. Variantes anatômicas podem contribuir para um maior risco de LVB durante colecistectomia. OBJETIVOS: Relatar paciente com lesão de via biliar associado a situs inversus totalis. MÉTODOS: Paciente do sexo feminino, 42 anos, com histórico prévio de situs inversus totalis e LVB inicialmente reparada simultaneamente à lesão, há 10 anos, por um cirurgião não especializado. Ela foi encaminhada a um centro especializado devido a episódios recorrentes de colangite e um padrão laboratorial colestático. Colangiressonância revelou uma grave estenose anastomótica. Devido à sua idade jovem e colangites recorrentes, foi submetida a uma revisão cirúrgica da hepaticojejunostomia com técnica de Hepp-Couinaud. Até onde sabemos, este é o primeiro relato de reparo de LVB em um paciente com situs inversus totalis. RESULTADOS: A hepaticojejunostomia realizado prèviamente foi desfeita e refeita empregando a técnica de Hepp-Couinaud, alta na placa hilar, com uma ampla abertura na confluência dos ductos biliares em direção ao ducto hepático esquerdo. A alça de roux anterior foi mantida. A recuperação pós-operatória transcorreu sem intercorrências, o dreno foi removido no sétimo dia pós-operatório, e a paciente está agora assintomática, com bilirrubina e enzimas canalículares normais, e sem mais episódios de colestase ou colangite. CONCLUSÕES: Variantes anatômicas podem aumentar a dificuldade tanto da colecistectomia quanto do reparo de LVB, o qual deve ser realizado em um centro especializado por cirurgiões hepatobiliares para garantir um manejo perioperatório seguro e um bom resultado a longo prazo.

Subtotal Cholecystectomy After Failed Critical View of Safety Is an Effective and Safe Bail Out Strategy.

BACKGROUND: Bile duct injury (BDI) is accompanied by significant morbidity and long-term impact in quality of life. Subtotal cholecystectomy (STC) is an alternative to prevent this outcome but is associated with other complications. The aim of this work is to demonstrate that BDI associated morbidity exceeds STC associated morbidity, underscoring STC as a reasonable bail out strategy. METHODS: We compared 115 patients who underwent STC with 293 patients who were referred to our center with BDI type E1-E3 and underwent surgical repair. The groups were comparable because in both instances the surgeon had the opportunity to decide not to perform a total cholecystectomy once critical view of safety (CVS) was not achieved. RESULTS: Bile leakage was found in 21% of the STC group with only one BDI (0.9%). More Accordion ≥ 4 were found in the STC group (10.4% vs 4.8%, p = 0.035); however, reoperations were more frequent in the BDI group (8.2% vs 0.9%, p = 0.006). No patient in the STC group required reintervention for completion cholecystectomy. After 3.8 years follow-up, 2.4% of patients had secondary biliary cirrhosis in the BDI group; none in the STC group. CONCLUSIONS: Despite complications of STC, morbidity associated with BDI is much higher due to high long-term reoperation rate, in addition to secondary biliary cirrhosis. STC is a safe alternative that can prevent BDI if properly and timely performed in the context of difficult cholecystectomy.

Choices of Therapeutic Strategies for Colorectal Liver Metastases Among Expert Liver Surgeons: A Throw of the Dice?

OBJECTIVE: To test the degree of agreement in selecting therapeutic options for patients suffering from colorectal liver metastasis (CRLM) among surgical experts around the globe. SUMMARY/BACKGROUND: Only few areas in medicine have seen so many novel therapeutic options over the past decades as for liver tumors. Significant variations may therefore exist regarding the choices of treatment, even among experts, which may confuse both the medical community and patients. METHODS: Ten cases of CRLM with different levels of complexity were presented to 43 expert liver surgeons from 23 countries and 4 continents. Experts were defined as experienced surgeons with academic contributions to the field of liver tumors. Experts provided information on their medical education and current practice in liver surgery and transplantation. Using an online platform, they chose their strategy in treating each case from defined multiple choices with added comments. Inter-rater agreement among experts and cases was calculated using free-marginal multirater kappa methodology. A similar, but adjusted survey was presented to 60 general surgeons from Asia, Europe, and North America to test their attitude in treating or referring complex patients to expert centers. RESULTS: Thirty-eight (88%) experts completed the evaluation. Most of them are in leading positions (92%) with a median clinical experience of 25 years. Agreement on therapeutic strategies among them was none to minimal in more than half of the cases with kappa varying from 0.00 to 0.39. Many general surgeons may not refer the complex cases to expert centers, including in Europe, where they also engage in complex liver surgeries. CONCLUSIONS: Considerable inconsistencies of decision-making exist among expert surgeons when choosing a therapeutic strategy for CRLM. This might confuse both patients and referring physicians and indicate that an international high-level consensus statements and widely accepted guidelines are needed.

Acute Cholangitis After Bilioenteric Anastomosis for Bile Duct Injuries.

BACKGROUND/PURPOSE: The study aims to describe the clinical features, microbiology, and associated factors of acute cholangitis (AC) after bilioenteric anastomosis (BEA) for biliary duct injury (BDI). Additionally, we assessed the performance of the Tokyo Guidelines 2013 (TG13) recommendations in these patients. METHODS: We conducted a case-control study of 524 adults with a history of BEA for BDI from January 2000 to January 2014. A propensity score adjustment was performed for the analysis of the independent role of the main factors identified during the univariate logistic regression procedure. RESULTS: We identified 117 episodes of AC in 70 patients; 51.3% were definitive AC according to the TG13 diagnostic criteria, and 39.3% did not fulfill the imaging criteria of AC. A history of post-operative biliary complications (OR 2.55, 95% CI 1.38-4.70) and the bile duct confluence preservation (OR 0.46, 95% CI 0.24-0.87) were associated with AC. Eighty-nine percent of the microorganisms were Enterobacteriaceae; of them, 28% were extended spectrum ß-lactamase (ESBL) producers. CONCLUSIONS: AC is a common complication after BEA and must be suspected even in the absence of imaging findings, particulary in patients with a history of post-operative biliary complications, and/or without bile duct confluence preserved. An empirical treatment for ESBL-producing Enterobacteriaceae may be appropriate in patients living in countries with a high rate of bacterial drug resistance.

A rare case of choledochal cyst with pancreas divisum: case presentation and literature review.

Choledochal cysts are rare congenital malformations of the bile duct characterized by dilatations of the intrahepatic and/or extrahepatic portion of the biliary tree, they are associated to an anomalous arrangement of the pancreaticobiliary duct. Pancreas divisum results from a fusion failure of the pancreatic buds. The coexistence of pancreas divisum and choledochal cyst in adults has been reported in less than 10 well documented cases. This article presents a case of a 42-year-old Peruvian man with intermittent episodes of abdominal pain, initially diagnosed with choledocholithiasis, who underwent open cholecystectomy. During surgery, a diagnosis of choledochal cyst and pancreas divisum was made, and therefore a hepaticoduodenostomy was performed. The patient was referred to our hospital due to persistence of abdominal pain. After admission, a papillectomy was achieved without further complications. A cyst resection and dismantling of hepaticoduodenostomy with Roux-en-Y was performed 8 years later. During the subsequent 18-month follow-up, the patient remains asymptomatic.

Iatrogenic bile duct injury with loss of confluence.

AIM: To describe our experience concerning the surgical treatment of Strasberg E-4 (Bismuth IV) bile duct injuries. METHODS: In an 18-year period, among 603 patients referred to our hospital for surgical treatment of complex bile duct injuries, 53 presented involvement of the hilar confluence classified as Strasberg E4 injuries. Imagenological studies, mainly magnetic resonance imaging showed a loss of confluence. The files of these patients were analyzed and general data were recorded, including type of operation and postoperative outcome with emphasis on postoperative cholangitis, liver function test and quality of life. The mean time of follow-up was of 55.9 ± 52.9 mo (median = 38.5, minimum = 2, maximum = 181.2). All other patients with Strasberg A, B, C, D, E1, E2, E3, or E5 biliary injuries were excluded from this study. RESULTS: Patients were divided in three groups: G1 (n = 21): Construction of neoconfluence + Roux-en-Y hepatojejunostomy. G2 (n = 26): Roux-en-Y portoenterostomy. G3 (n = 6): Double (right and left) Roux-en-Y hepatojejunostomy. Cholangitis was recorded in two patients in group 1, in 14 patients in group 2, and in one patient in group 3. All of them required transhepatic instrumentation of the anastomosis and six patients needed live transplantation. CONCLUSION: Loss of confluence represents a surgical challenge. There are several treatment options at different stages. Roux-en-Y bilioenteric anastomosis (neoconfluence, double-barrel anastomosis, portoenterostomy) is the treatment of choice, and when it is technically possible, building of a neoconfluence has better outcomes. When liver cirrhosis is shown, liver transplantation is the best choice.

Quality of life in bile duct injury: 1-, 5-, and 10-year outcomes after surgical repair.

BACKGROUND: Quality of life after bile duct injury is a relevant health issue besides physician-oriented outcomes. A prospective study was performed to explore short- and long-term outcomes after surgical repair. METHOD: We studied a cohort of patients with Strasberg E injuries who underwent Roux-en-Y jejunal anastomosis from 1990 to 2008. The Short Form Health Survey (SF-36) was selected as the appropriate quality of life assessment instrument. Two groups were comprised: Group I included patients with 10-year follow-up after surgery. Group II included patients operated during 2008 with preoperative 1- and 5-year questionnaires. RESULTS: Group I patients (N = 41) were operated from 1990 to 2003 and Group II (N = 44) during 2008. There is a significant improvement in quality of life after the first year of repair in all domains. Readmissions (48 vs 25 %; p < 0.01), colangitis (46 vs 14 %; p < 0.001), and hepatojejunal redo (26 vs. 4 %; p < 0.0001) were less frequent in Group II. No differences in quality of life summary scores were found between Group I and II. CONCLUSIONS: Quality of life improves significantly after the first year of surgical repair, reaching a plateau at 5 years. No correlation exists with physician-centered outcomes.

Hepatolithiasis with secondary cholangitis and supernumerary left hepatic lobe.

We report the case of a 31-year old woman with recurrent cholangitis secondary to hepatolithiasis. The stones were composed of calcium bilirubinate. The patient also had a supernumerary hepatic lobe connected to the inferior aspect of the segment III of the liver. The role of the supernumerary hepatic lobe in the development of hepatolithiasis is unclear and may be coincidental.

Adenocarcinoma with pyloric gland phenotype of the extrahepatic bile ducts: a previously unrecognized and distinctive morphologic variant of extrahepatic bile duct carcinoma.

Carcinomas of the extrahepatic bile ducts are uncommon and morphologically heterogeneous. We report 3 unique examples of adenocarcinomas that show predominantly pyloric gland differentiation (80%-100%) and compare their immunohistochemical profile with that of pyloric gland adenomas of the gallbladder, foveolar, and intestinal-type adenocarcinomas of the extrahepatic bile duct. The 3 patients with pyloric gland adenocarcinomas were younger than those with conventional adenocarcinomas. The 3 tumors were very well differentiated but showed extensive perineural invasion. They consisted of a variable proportion of small, medium-sized, and cystically dilated glands separated by abundant desmoplastic stroma. The glands were lined by columnar cells with abundant mucin-containing cytoplasm and small hyperchromatic basally placed nuclei with inconspicuous nucleoli. A characteristic feature of these pyloric gland adenocarcinomas was that the glands had a stellar pattern that was not seen in foveolar-, intestinal-, or biliary-type adenocarcinomas. Two pyloric gland adenocarcinomas coexpressed MUC6 and MUC5AC. The diffuse pattern of reactivity of MUC5AC and MUC6 was similar to that of 10 pyloric gland adenomas of the gallbladder and 2 foveolar adenocarcinomas of the extrahepatic bile duct. In contrast, 5 intestinal adenocarcinomas of the extrahepatic bile duct labeled with the intestinal marker CDX2 and 3 with the colonic MUC2 but were negative for MUC6 and MUC5AC. We believe that these pyloric gland adenocarcinomas represent a previously unrecognized distinct clinicopathologic entity. Despite their deceptively benign microscopic appearance, 1 patient died with local recurrence and liver metastasis, another patient is living with tumor, and the third patient is asymptomatic but only 5 months after surgery.

Transition from a low: to a high-volume centre for bile duct repair: changes in technique and improved outcome.

BACKGROUND: Improvements in bile duct injury repairs have been shown in centres with specialized surgeons. The aim of the present study was to demonstrate the temporal change in the pattern of referral, technical variation associated with repair and long-term outcome of bile duct injuries at a tertiary referral centre in Mexico City. METHODS: A retrospective case note review was performed. Patients were divided into two groups: group I (GI) 1990 to 2004 and group II (GII) 2005-2008, and appropriate statistical analysis undertaken. RESULTS: Over a 20-year period, 312 patients with iatrogenic bile duct injuries required surgical treatment (GI = 169, GII = 140 patients). All injuries were reconstructed using a Roux-en-Y hepaticojejunostomy. The proportion of patients who had undergone a laparoscopic cholecystectomy increased from 24% to 36% (P = 0.017) over the two time periods. In the second time period there was an increase in segment IV and V partial resections (P = 0.020), a reduction in the use of transanastomotic stents (42% to 2%, P = 0.001) and an increase in the proportion of patients requiring a neoconfluence (2% to 11%, P = 0.003). In the second time period, the number of patients requiring a hepatectomy during repair (2% to 1%, P = 0.001), a portoenterostomy (16% to 9%, P = 0.060) or a double-barrel hepatico-jejunostomy (5% to 1%, P = 0.045) significantly decreased. During follow-up, patients in the second time period had a reduction in the incidence of post-operative cholangitis (11% to 6%, P = 0.310) and the frequency of post-operative anastomotic stenoses (13% to 5%, P = 0.010). Mortality remained low throughout the series but was absent in the second group. CONCLUSIONS: Changes in technique and growing experience of the multidisciplinary team improved operative and long-term results of bile duct injury repair.

Liver segment IV hypoplasia as a risk factor for bile duct injury.

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.

Classification and management of bile duct injuries.

To review the classification and general guidelines for treatment of bile duct injury patients and their long term results. In a 20-year period, 510 complex circumferential injuries have been referred to our team for repair at the Instituto Nacional de Ciencias Médicas y Nutrición "Salvador Zubirán" hospital in Mexico City and 198 elsewhere (private practice). The records at the third level Academic University Hospital were analyzed and divided into three periods of time: GI-1990-99 (33 cases), GII- 2000-2004 (139 cases) and GIII- 2004-2008 (140 cases). All patients were treated with a Roux en Y hepatojejunostomy. A decrease in using transanastomotic stents was observed (78% vs 2%, P = 0.0001). Partial segment IV and V resection was more frequently carried out (45% vs 75%, P = 0.2) (to obtain a high bilioenteric anastomosis). Operative mortality (3% vs 0.7%, P = 0.09), postoperative cholangitis (54% vs 13%, P = 0.0001), anastomosis strictures (30% vs 5%, P = 0.0001), short and long term complications and need for reoperation (surgical or radiological) (45% vs 11%, P = 0.0001) were significantly less in the last period. The authors concluded that transition to a high volume center has improved long term results for bile duct injury repair. Even interested and tertiary care centers have a learning curve.

Intrahepatic bilioenteric anastomosis after biliary complications of liver transplantation: operative rescue of surgical failures.

BACKGROUND: Biliary complications after orthotopic liver transplantation (OLT) are multifactorial in origin. In most series, the frequency of such complications ranges from 5-20%. Most can be treated by endoscopy and/or interventional radiology. For cases in which this option is not successful, surgical approach is indicated. We report the results of reoperation using an intrahepatic bilioenteric anastomosis. METHODS: The medical charts of patients with biliary complications after OLT during a 10-year period (1997-2007), who failed to respond to nonsurgical treatment and were surgically treated, were reviewed. Roux-en-Y hepatojejunostomy was performed. Segments IV and V were partially removed after cutting the hilar plate, thus obtaining healthy ducts without ischemic or inflammatory reaction and allowing a wide hepatojejunostomy. RESULTS: Five cases (8.4%) with biliary complications after duct-to-duct anastomosis not amenable to further endoscopic management or interventional radiology were identified. Hepaticojejunostomy was achieved in all cases (wide, tension-free, nonischemic, fine hydrolyzable sutures), and segments IV and V were partially removed. No cholangitis, jaundice, and liver function test abnormalities were present in the postoperative. Mean follow-up was 24 months. Only one patient died of causes not related to bile duct reconstruction during follow-up. CONCLUSIONS: Intrahepatic hepatojejunostomy with partial resection of segments IV and V offers an excellent therapeutic alternative for biliary complications that require a surgical approach after OLT.

Voluntary and involuntary ligature of the bile duct in iatrogenic injuries: a nonadvisable approach.

BACKGROUND: Bile duct injuries related to laparoscopic and/or open cholecystectomy are a frequent finding and require surgical treatment. Complete obstruction is due to either intentionally or unintentionally placed ligatures or clips. The intentional application is usually performed to "facilitate identification of the duct by bile duct dilation." Considering that we are a national referral center for such injuries, we decided to analyze our cases of voluntary and involuntary duct ligation after iatrogenic bile duct injury. METHODS: We reviewed the files of patients with voluntary or involuntary bile duct ligation. Results of preoperative evaluation of the ducts, operative treatment, and postoperative results were analyzed. RESULTS: A total of 413 patients were included. Forty-five patients presented with complete obstruction. In 15 cases, the ligature was intentional, and in 30 cases, occlusion was involuntary. Bile duct dilation (>10 mm) was demonstrated in one case of voluntary (6%) and three cases of involuntary ligations (10%). The remaining cases in both groups had no duct dilation and developed necrosis at the blinded duct and leakage proximal to the ligature, with different degrees of bilioperitoneum and/or biloma. In all cases, a Roux-en-Y hepatojejunostomy was performed. CONCLUSION: Bile duct ligature produces dilation in a very small number of patients (less than 10%) and usually produces necrosis of the blinded stump with subsequent bile leakage. Placement of a subhepatic drain and transference of the patient to a qualified center for reconstruction is the best approach if the primary surgeon is not able to do the repair.

Intrahepatic repair of bile duct injuries. A comparative study.

INTRODUCTION: The frequency of bile duct injuries associated to cholecystectomy remains constant (0.3-0.6%). A multidisciplinary approach (endoscopical, radiological, and surgical) is necessary to optimize the outcome of the patient. Surgery is indicated when complete section of the duct is identified (Strasberg's E injuries) requiring a bilioenteric anastomosis as treatment. Nowadays, the most frequent technique used for reconstruction is a Roux-en-Y hepatojejunostomy. Long-term results of reconstruction are related to several technical and anatomic factors, but an ischemic duct (with subsequent scarring) plays a mayor role. In this paper, we report the results of biliary reconstructions comparing the extrahepatic-probably ischemic -- to intrahepatic -- non ischemic -- repairs. METHODS: We reviewed the files of patients referred to our hospital (third-level teaching hospital) for bile duct repair after iatrogenic injury from 1990 to July 2006. Injury classification, time lapse since injury, surgical repair technique, and long-term follow-up were noted. In all cases, a Roux-en-Y hepatojejunostomy was done. Partial resection of segment IV was performed in 136 patients to obtain noninflamed, nonscarred, nonischemic biliary ducts with the purpose of reaching the confluence and achieving a high-quality bilioenteric anastomosis. An anastomosis at the level of the confluence was attempted in 293 patients (in 198 the confluence was preserved and in 95 it was lost). In the remaining 80 patients, a low bilioenteric anastomosis was done at the level of the common hepatic duct. We compared intrahepatic (198) and extrahepatic (80) repairs. RESULTS: A total of 405 cases (88 males, 317 females) were identified, with a mean age of 42 years (range 17-75). All of the injuries were classified as Strasberg E1, E2, E3, E5 (less frequent); those with E4 classification (separated ducts) were excluded. In all cases, the confluence was preserved (N = 293). Thirty-two cases were repaired minutes to hours after the injury occurred. The remaining 373 patients arrived weeks after the injury. In 198 cases, an intrahepatic repair was done, including the 136 in which resection of segments IV and V was part of the surgery. In the remaining 80 cases (operated between 1990 and 1997), an extrahepatic repair was done at the level of the common hepatic duct where the surgeon found a healthy duct. Twelve (15%) of the 80 cases with extrahepatic anastomosis required a new intervention (surgical or radiological), compared to only 8 of the 198 (3%) that had an intrahepatic anastomosis (P = 0.00062). Good results were obtained in 85% and 97% of the cases with extrahepatic anastomosis and intrahepatic anastomosis, respectively. Both groups had a reintervention rate of 7% (20/278). CONCLUSIONS: An intrahepatic anastomosis requires finding nonscarred, nonischemic ducts, thus allowing a safe and high-quality anastomosis with significantly better results when compared to the low-level anastomosis group.
