RESUMEN
BACKGROUND: Perihilar cholangiocarcinoma is a challenging technique to be performed by minimally invasive approach being the type III among the most complex procedure. Nowadays, the robotic approach is gaining increasing interest among the surgical community, and more and more series describing robotic liver resection have been reported. However, few cases of minimally invasive Bismuth type IIIA cholangiocarcinoma have been reported. Robotic approach allows for a better dissection and suture thanks to the flexible and precise instruments movements, overcoming some of the limitations of the laparoscopic technique. Therefore, robotic technique can facilitate some of the critical steps of a technically demanding procedure, such as the extended right hepatectomy for perihilar cholangiocarcinoma Bismuth IIIA type. METHODS: In this multimedia video we describe, for the first time in the literature, a full robotic surgical step-by-step technique with some tips and tricks for treating a perihilar cholangiocarcinoma Bismuth IIIA type, performing a radical extended right hemihepatectomy, including segment I combined with regional lymphadenectomy anf left bile duct reconstruction. A 55-year-old woman with obstructive jaundice (10 mg/dl) was referred to our center. The endobiliary brushing confirmed adenocarcinoma, and MRI/CT showed a focal perihilar lesion of 2 cm, including the main biliary duct bifurcation and extending up to the right duct (Bismuth Type IIIA hilar cholangiocarcinoma). After endoscopic biliary stents placement and 6 weeks after right portal vein embolization, the future liver remnant, including segments II and III, reached an enough hypertrophy volume with a ratio of 30%. A right hemihepatectomy with caudate lobe, including standard standard lymphadenectomy and left biliary duct reconstruction was performed. RESULTS: The operation lasted 670 min with an estimated blood loss of 350 ml. Postoperative pathological examination revealed a moderately differentiated adenocarcinoma pT1N0 with 15 retrieved nodes and free margins. The patient experienced a type A biliary fistula and was discharged on the 21st postoperative day without abdominal drainage. CONCLUSIONS: Through the tips and tricks presented in this multimedia article, we show the advantages of the robotic approach for performing correctly one of the most complex surgeries.1-7.

BACKGROUND: Hepatectomy combined with hepatic artery reconstruction in the operation for hilar cholangiocarcinoma (Klatskin tumor) is a challenging procedure. We present a video of left hepatectomy combined with right hepatic artery reconstruction for hilar cholangiocarcinoma. PATIENT AND METHODS: The patient was a 60-year-old male who presented with obstructive jaundice. The imaging examination showed that the confluence of left and right hepatic ducts and the wall of common hepatic duct were thickened, the local lumen was narrowed, the intrahepatic bile duct was dilated, and the right hepatic artery was invaded by tumors nearly 2.3 centimeters. Left hepatectomy with total caudate lobectomy, resection with reconstruction of right hepatic artery, hilar lymphadenectomy, and Roux-en-Y hepaticojejunostomy were performed. RESULTS: The operation time was 345 min, and the amount of bleeding was about 400 ml. There was no blood transfusion. The pathology showed poorly differentiated adenocarcinoma, with negative margins of common bile duct and right hepatic duct, and negative results of all lymph nodes. The patient's recovery was uneventful and he was discharged on postoperative day 14. The patient was disease free at 12-month follow-up evaluation. CONCLUSIONS: Hepatic artery resection and reconstruction procedure is safe and feasible for hilar cholangiocarcinoma in a highly tertiary hepatobiliary center.

BACKGROUND: Minimally invasive resection for perihilar cholangiocarcinoma is a complicated and technically demanding surgical procedure. Radical surgical resection is regarded as the best treatment for hepatic hilar cholangiocarcinoma.1,2 Right hepatectomy with caudate lobe resection is necessary as the treatment for bismuth IIIa hilar cholangiocarcinoma.3 The left-liver-first anterior radical modular orthotopic right hemihepatectomy (LARMORH), which can simplify surgical steps and decrease procedural difficulty, may be a better choice for Bismuth IIIa hilar cholangiocarcinoma.4 However, there are no reports of this approach using robotic technique for this operation. We will provide a detailed introduction to this method through this video. METHODS: A 45-year-old female patient was diagnosed with a hilar cholangiocarcinoma. Following a 7-day percutaneous biliary drainage of the left intrahepatic bile duct and obtaining informed consent, we performed a robotic radical resection of the HCCA using the LARMORH approach. The patient was positioned supine with the entire bed elevated 20° and tilted 15° to the left. Trocars were placed in position (Fig. 1). After entering the abdominal cavity, it was explored for tumor metastasis. The surgery adopted a left approach, initially exploring the left hepatic artery and vein to further assess resectability. After confirming resectability, the right hepatic artery and gastroduodenal artery (GDA) were dissected. The common bile duct was dissected and transected at its distal end, ensuring R0 surgical margins. Lymph nodes were cleared from the foot side to the head side, confirming the metastasis to the lymph node group 13a, so we further cleared the group 16 and 9 lymph nodes.5 Subsequently, we approached the resection of the right half and the entire caudate lobe with the reverse thinking of left hepatic resection mode, preserving only the left branch of the portal vein and left hepatic artery, and dissecting the liver tissue along the resection plane of the left liver. After transection of the left hepatic duct, the activity space of the left liver was larger and the caudate lobe could be better exposed. The Spiegel lobe was lifted to the right in a "turn the page" fashion for in situ resection of the entire caudate lobe and the right half of the liver. Finally, a bilioenteric anastomosis was performed using the Roux-en-Y method. RESULTS: Robotic right hepatectomy with caudate lobectomy was successfully performed in 450 min, with an estimated blood loss of 200 ml. The histological grading was determined as T1aN1M0 (stage IIIB) on the basis of postoperative pathological biopsy results. The patient achieved a satisfactory postoperative recovery and was discharged on the 14th postoperative day without any major complications. Following the operation, the patient received capecitabine chemotherapy according to the Chinese Society of Clinical Oncology (CSCO) criteria. Since September 2022, our team has completed three radical resections for Bismuth IIIa HCCA using this technique. All patients achieved a satisfactory postoperative recovery without any further complications. CONCLUSIONS: Robotic left-liver-first anterior radical modular orthotopic right hemihepatectomy for Bismuth IIIa HCCA is both safe and feasible. This method may provide a new surgical approach for patients with type IIIA HCCA or liver diseases requiring right hemihepatectomy combined with total caudate lobectomy.

BACKGROUND: The application of three-dimensional (3D) reconstruction has been extensively adopted in hepatectomy navigation,1 yet its utilization in laparoscopic radical resection of perihilar cholangiocarcinoma (pHCCA) remains underexplored. VIDEO: A 54-year-old male patient, classified as Child-Pugh B, presented a small neoplasm situated at the left hepatic duct proximate to the right hepatic and common hepatic ducts. An enhanced abdominal computed tomographic scan identified a solitary lesion measuring 2.8 × 2.4 cm. 3D reconstruction exposed tumor invasion into the left hepatic artery and left portal vein. Given the lesion's unique location, a pure laparoscopic left hepatectomy and caudate lobectomy were executed using a no-touch en block technique post patient consent. Concurrently, extrahepatic bile duct resection, radical lymphadenectomy with skeletonization, and biliary reconstruction were performed. RESULTS: The 3D reconstruction-guided laparoscopic left hepatectomy and caudate lobectomy were successfully completed in 425 min with minimal blood loss (50 mL). The histological grading was T2bN0M0 (stage II). The patient was discharged on the sixth postoperative day without complications, and postoperative treatment included mono-drug chemotherapy with capecitabine. No recurrence was observed at the 6-month follow-up. CONCLUSION: Our experience suggests that 3D reconstruction-guided laparoscopic radical resection may offer increased precision and efficiency in selected pHCCA patients. This approach can potentially yield outcomes comparable with or superior to open surgery, given standardized lymph node dissection by skeletonization, use of the no-touch en block technique, appropriate digestive tract reconstruction, and reduced bleeding and liver damage.

BACKGROUND: A right- or left-sided liver resection can be considered in about half of patients with perihilar cholangiocarcinoma (pCCA), depending on tumor location and vascular involvement. This study compared postoperative mortality and long-term survival of right- versus left-sided liver resections for pCCA. METHODS: Patients who underwent major liver resection for pCCA at 25 Western centers were stratified according to the type of hepatectomy-left, extended left, right, and extended right. The primary outcomes were 90-day mortality and overall survival (OS). RESULTS: Between 2000 and 2022, 1701 patients underwent major liver resection for pCCA. The 90-day mortality was 9% after left-sided and 18% after right-sided liver resection (p < 0.001). The 90-day mortality rates were 8% (44/540) after left, 11% (29/276) after extended left, 17% (51/309) after right, and 19% (108/576) after extended right hepatectomy (p < 0.001). Median OS was 30 months (95% confidence interval [CI] 27-34) after left and 23 months (95% CI 20-25) after right liver resection (p < 0.001), and 33 months (95% CI 28-38), 27 months (95% CI 23-32), 25 months (95% CI 21-30), and 21 months (95% CI 18-24) after left, extended left, right, and extended right hepatectomy, respectively (p < 0.001). A left-sided resection was an independent favorable prognostic factor for both 90-day mortality and OS compared with right-sided resection, with similar results after excluding 90-day fatalities. CONCLUSIONS: A left or extended left hepatectomy is associated with a lower 90-day mortality and superior OS compared with an (extended) right hepatectomy for pCCA. When both a left and right liver resection are feasible, a left-sided liver resection is preferred.

BACKGROUND: Robotic technology is increasingly utilized in perihilar cholangiocarcinoma treatments, requiring expertise in minimally invasive liver surgeries and biliary reconstructions. These resections often involve vascular and multiple sectoral bile duct reconstructions. Minimally invasive vascular repairs are now emerging with promising outcomes, potentially altering criteria for selecting minimally invasive hepatobiliary tumor resections. In this multimedia article, we describe our technique of robotic portal venous tangential primary reconstruction with right sectoral bile duct unification ductoplasty for the treatment of perihilar cholangiocarcinoma using the robotic approach. METHODS: The robotic technique was chosen in this operation with preoperative anticipation of needing vascular resection and reconstruction due to left portal vein tumor involvement. Additionally, a Roux-en-Y hepaticojejunostomy to the right anterior and posterior sectoral duct was planned for biliary reconstruction. Proximal and distal vascular control of the portal vein bifurcation was obtained by placing vascular bulldog clamps across the main and right portal veins. Once an R0 vascular margin was obtained on the left portal vein, portal bifurcation was tangentially repaired. Perfusion to the liver was then restored, and left hemihepatectomy with en bloc extrahepatic biliary resection was carried out, followed by Roux-en-Y hepaticojejunostomy reconstruction to the right anterior and posterior sectoral bile ducts, as a single anastomosis. RESULTS: The operation was uneventful without vascular or biliary complications. Robotic unification ductoplasty circumvented the need for multiple anastomoses. CONCLUSION: The robotic approach for left-sided perihilar cholangiocarcinoma resections, requiring precise biliovascular management, is safe, feasible, and efficient. This method demonstrates the potential of robotic techniques as an alternative to traditional open surgery.

BACKGROUND: The prognostic impact of positive peritoneal lavage cytology (CY+) in patients with perihilar cholangiocarcinoma (PHC) remains unclear. The present study investigated the clinical significance of primary tumor resection of CY+ PHC. METHODS: We retrospectively evaluated 282 patients who underwent surgery for PHC between September 2002 and March 2022. The patients' clinicopathological characteristics and survival outcomes were compared between the CY negative (CY-) resected (n = 262), CY+ resected (n = 12), and CY+ unresected (n = 8) groups. Univariate and multivariate analyses were performed to identify prognostic factors for overall survival. RESULTS: The expected residual liver volume was significantly higher in the CY+ resected group (61%) than in the CY- resected (47%) and CY+ unresected (37%) groups (p = 0.004 and 0.007, respectively). The CY+ resected group had a higher administration rate of postoperative therapy than the CY- resected group (58% vs. 16%, p = 0.002). Overall survival of the CY+ resected group was similar to that of the CY- resected group (median survival time [MST] 44.5 vs. 44.6, p = 0.404) and was significantly better than that of the CY+ unresected group (MST 44.5 vs. 17.1, p = 0.006). CY positivity was not a prognostic factor according to a multivariate analysis in patients with primary tumor resection. CONCLUSIONS: The CY+ resected group showed better survival than the CY+ unresected group and a similar survival to that of the CY- resected group. Resection of the primary tumor with CY+ PHC may improve the prognosis in selected patients.

BACKGROUND: The management of Bismuth-Corlette type IV hilar cholangiocarcinoma typically necessitates extensive hepatectomy, resection of the extrahepatic bile ducts, regional lymph node dissection, and reconstruction of the biliary tract; however, there is a high incidence of postoperative liver dysfunction and failure. METHODS: A 64-year-old male patient was admitted to our department after 1 month of escalating jaundice and abdominal discomfort. Upon admission, his total bilirubin was 334 µmol/L and his direct bilirubin was 221 µmol/L. His carbohydrate antigen 19-9 was > 1200.00 U/mL, his carcinoembryonic antigen was 98.90 U/mL, and his α-fetoprotein was normal. Enhanced computed tomography (CT) and magnetic resonance imaging scans revealed a thickened and enlarged biliary tree extending from the common hepatic duct to the orifices of the left and right hepatic ducts. RESULTS: The patient underwent total laparoscopic radical resection of S1 + S4, accompanied by radical lymphadenectomy with skeletonization and biliary reconstruction. The surgery was successfully conducted within 450 min, with a minimal blood loss of 200 mL. The histological grading was T2bN1M0 (stage III). CT on postoperative day 5 showed satisfactory postoperative recovery. The patient was discharged from the hospital on postoperative day 10 without complications, following which the patient underwent a regimen of single-agent capecitabine chemotherapy. Over a 20-month follow-up period, no recurrence was observed. CONCLUSIONS: Resection of hepatic segments S1 + S4 is a viable surgical option for hilar carcinoma in cases with poor liver function or when the carcinoma is confined to both hepatic ducts without invasion of the hepatic artery and portal vein.

BACKGROUND: Surgical resection for perihilar cholangiocarcinoma (pCCA) is associated with high operative risks. Impaired liver regeneration in patients with pre-existing liver disease may contribute to posthepatectomy liver failure (PHLF) and postoperative mortality. This study aimed to determine the incidence of hepatic steatosis and fibrosis and their association with PHLF and 90-day postoperative mortality in pCCA patients. METHODS: Patients who underwent a major liver resection for pCCA were included in the study between 2000 and 2021 from three tertiary referral hospitals. Histopathologic assessment of hepatic steatosis and fibrosis was performed. The primary outcomes were PHLF and 90-day mortality. RESULTS: Of the 401 included patients, steatosis was absent in 334 patients (83.3%), mild in 58 patients (14.5%) and moderate to severe in 9 patients (2.2%). There was no fibrosis in 92 patients (23.1%), periportal fibrosis in 150 patients (37.6%), septal fibrosis in 123 patients (30.8%), and biliary cirrhosis in 34 patients (8.5%). Steatosis (≥ 5%) was not associated with PHLF (odds ratio [OR] 1.36; 95% confidence interval [CI] 0.69-2.68) or 90-day mortality (OR 1.22; 95% CI 0.62-2.39). Neither was fibrosis (i.e., periportal, septal, or biliary cirrhosis) associated with PHLF (OR 0.76; 95% CI 0.41-1.41) or 90-day mortality (OR 0.60; 95% CI 0.33-1.06). The independent risk factors for PHLF were preoperative cholangitis (OR 2.38; 95% CI 1. 36-4.17) and future liver remnant smaller than 40% (OR 2.40; 95% CI 1.31-4.38). The independent risk factors for 90-day mortality were age of 65 years or older (OR 2.40; 95% CI 1.36-4.23) and preoperative cholangitis (OR 2.25; 95% CI 1.30-3.87). CONCLUSION: In this study, no association could be demonstrated between hepatic steatosis or fibrosis and postoperative outcomes after resection of pCCA.

BACKGROUD: We aimed to develop a novel preoperative nomogram to predict lymph node metastasis (LNM) in perihilar cholangiocarcinoma (pCCA) patients. METHODS: 160 pCCA patients were enrolled at Lihuili Hospital from July 2006 to May 2022. A novel nomogram model was established to predict LNM in pCCA patients based on the independent predictive factors selected by the multivariate logistic regression model. The precision of the nomogram model was evaluated through internal and external validation with calibration curve statistics and the concordance index (C-index). Receiver operating characteristic (ROC) curve and decision curve analysis (DCA) were used to evaluate and determine the clinical utility of the nomogram. RESULTS: Multivariate logistic regression demonstrated that age (OR = 0.963, 95% CI: 0.930-0.996, P = 0.030), CA19-9 level (> 559.8 U/mL vs. ≤559.8 U/mL: OR = 3.162, 95% CI: 1.519-6.582, P = 0.002) and tumour diameter (OR = 1.388, 95% CI: 1.083-1.778, P = 0.010) were independent predictive factors of LNM in pCCA patients. The C-index was 0.763 (95% CI: 0.667-0.860) and 0.677 (95% CI: 0.580-0.773) in training cohort and validation cohort, respectively. ROC curve analysis indicated the comparative stability and adequate discriminative ability of nomogram. The sensitivity and specificity were 0.820 and 0.652 in training cohort and 0.704 and 0.649 in validation cohort, respectively. DCA revealed that the nomogram model could augment net benefits in the prediction of LNM in pCCA patients. CONCLUSIONS: The novel prediction model is useful for predicting LNM in pCCA patients and showed adequate discriminative ability and high predictive accuracy.

BACKGROUND AND OBJECTIVES: We aimed to describe our outcomes of robotic resection for perihilar cholangiocarcinoma, the largest single institutional series in the Western hemisphere to date. METHODS: Between 2016 and 2022, we prospectively followed all patients who underwent robotic resection for perihilar cholangiocarcinoma. RESULTS: In total, 23 patients underwent robotic resection for perihilar cholangiocarcinoma, 18 receiving concomitant hepatectomy. The median age was 73 years. Operative time was 470 min with an estimated blood loss of 150 mL. No intraoperative conversions to open or other intraoperative complications occurred. Median length of stay was 5 days. Four postoperative complications occurred. Three readmissions occurred within 30 days with one 90-day mortality. R0 resection was achieved in 87% of patients and R1 in 13% of patients. At a median follow-up of 27 months, 15 patients were alive without evidence of disease, two patients with local recurrence at 1 year, and six were deceased. CONCLUSIONS: Utilization of the robotic platform for perihilar cholangiocarcinoma is safe and feasible with excellent perioperative outcomes. Further studies are needed to determine the long-term oncological outcomes.

BACKGROUND: To assess the outcome of previously untreated patients with perihilar cholangiocarcinoma who present to a cancer referral center with or without pre-existing trans-papillary biliary drainage. METHODS: Consecutive patients with a diagnosis of perihilar cholangiocarcinoma presenting between January 1, 2013, and December 31, 2017, were identified from a prospective surgical database and by a query of the institutional database. Of 237 patients identified, 106 met inclusion criteria and were reviewed. Clinical information was obtained from the Electronic Medical Record and imaging studies were reviewed in the Picture Archiving and Communication System. RESULTS: 73 of 106 patients (69%) presenting with a new diagnosis of perihilar cholangiocarcinoma underwent trans-papillary biliary drainage (65 endoscopic and 8 percutaneous) prior to presentation at our institution. 8 of the 73 patients with trans-papillary biliary drainage (11%) presented with and 5 developed cholangitis; all 13 (18%) required subsequent intervention; none of the patients without trans-papillary biliary drainage presented with or required drainage for cholangitis (p = 0.008). Requiring drainage for cholangitis was more likely to delay treatment (p = 0.012) and portended a poorer median overall survival (13.6 months, 95%CI [4.08, not reached)] vs. 20.6 months, 95%CI [18.34, 37.51] p = 0.043). CONCLUSION: Trans-papillary biliary drainage for perihilar cholangiocarcinoma carries a risk of cholangitis and should be avoided when possible. Clinical and imaging findings of perihilar cholangiocarcinoma should prompt evaluation at a cancer referral center before any intervention. This would mitigate development of cholangitis necessitating additional drainage procedures, delaying treatment and potentially compromising survival.

BACKGROUND/PURPOSE: Endoscopic biliary stenting (EBS) is commonly used for preoperative drainage of localized perihilar cholangiocarcinoma (LPHC). This study retrospectively compared the utility of inside stent (IS) and conventional stent (CS) for preoperative EBS in patients with LPHC. METHODS: EBS was performed in 56 patients with LPHC. EBS involved the placement of a CS (n = 32) or IS (n = 24). Treatment outcomes were compared between these two groups. RESULTS: Preoperative recurrent biliary obstruction (RBO) occurred in 23 patients (71.9%) in the CS group and 7 (29.2%) in the IS group, with a significant difference (p = 0.002). The time to RBO (TRBO) was significantly longer in IS than in CS (log-rank: p < 0.001). The number of stent replacements was significantly lower in IS than CS [0.38 (0-3) vs. 1.88 (0-8), respectively; p < 0.001]. Gemcitabine-based neoadjuvant chemotherapy (NAC) was administered to 26 patients (46.4%). Among patients who received NAC, TRBO was longer in IS than in CS group (log-rank: p < 0.001). The IS group had a significantly shorter preoperative and postoperative hospital stay than the CS group (20.0 vs. 37.0 days; p = 0.024, and 33.5 vs. 41.5 days; p = 0.016).ã Both the preoperative and the postoperative costs were significantly lower in the IS group than in the CS group (p = 0.049 and p = 0.0034, respectively). CONCLUSION: Compared with CS, IS for preoperative EBS in LPHC patients resulted in fewer complications and lower re-intervention rates. The fact that the IS group had shorter preoperative and postoperative hospital stays and lower costs both preoperatively and postoperatively compared to the CS group may suggest that the use of IS has the potential to benefit not only the patient but also the healthcare system.

BACKGROUND: Prognosis of perihilar cholangiocarcinoma (PHCC) is poor, and curative-intent resection is the most effective treatment associated with long-term survival. Surgery is technically demanding since it involves a major hepatectomy with en bloc resection of the caudate lobe and extrahepatic bile duct. Furthermore, to achieve negative margins, it may be necessary to perform concomitant vascular resection or pancreatoduodenectomy. Despite this aggressive approach, recurrence is often observed, considering 5-year recurrence-free survival below 15% and 5-year overall survival that barely exceeds 40%. SUMMARY: The literature reports that survival rates are better in patients with negative margins, and surprisingly, R0 resections range between 19% and 95%. This variability is probably due to different surgical strategies and the pathologist's expertise with specimens. In fact, a proper pathological examination of residual disease should take into consideration both the ductal and the radial margin (RM) status. Currently, detailed pathological reports are lacking, and there is a likelihood of misinterpreting residual disease status due to the missing of RM description and the utilization of various definitions for surgical margins. KEY MESSAGES: The aim of PHCC surgery is to achieve negative margins including RM. More clarity in reporting on RM is needed to define true radical resection and consistent design of oncological studies for adjuvant treatments.

BACKGROUND: Postoperative complications after perihilar cholangiocarcinoma surgical procedure are still very high. The implementation of a multimodal prehabilitation program could improve these outcomes. Based on our experience and that of the literature in hepatobiliary and pancreatic surgery, we propose a protocol to promote its implementation. METHODS: First, we performed a retrospective analysis of the implementation feasibility of a multimodal prehabilitation program in patients' candidates for elective perihilar cholangiocarcinoma surgery in our center. Second, we conducted a literature search of publications in PubMed until December 2022. Relevant data about hepato-pancreato-biliary surgery and prehabilitation programs in features and postoperative outcomes was analyzed. RESULTS: Since October 2020, 11 patients were evaluated for prehabilitation in our hospital. Two of them could not be resected intraoperatively due to disease extension. The median hospital stay was 10 days (iqr, 7-11). There were no major complications and 1 patient died. Of a total of 17 articles related to prehabilitation in hepato-biliary-pancreatic surgery, no reports focusing exclusively on perihilar cholangiocarcinoma were found. Six of the studies had nutritional therapies in addition to physical interventions, and 12 studies used home-based exercise therapy. CONCLUSIONS: Based on our experience and the data obtained from other studies, a prehabilitation program could be useful to improve perioperative physical and mental fitness in patients' candidates for elective perihilar cholangiocarcinoma surgery. However, more well-designed studies are needed to allow us to obtain more evidence.

INTRODUCTION: Explorative laparotomy without subsequent curative-intent liver resection remains a major clinical problem in the treatment of perihilar cholangiocarcinoma (pCCA). Thus, we aimed to identify preoperative risk factors for non-resectability of pCCA patients. MATERIAL AND METHODS: Patients undergoing surgical exploration between 2010 and 2022 were eligible for the analysis. Separate binary logistic regressions analyses were used to determine risk factors for non-resectability after explorative laparotomy due to technical (tumor extent, vessel infiltration) and oncological (peritoneal carcinomatosis, distant nodal or liver metastases)/liver function reasons. RESULTS: This monocentric cohort comprised 318 patients with 209 (65.7%) being surgically resected and 109 (34.3%) being surgically explored [explorative laparotomy: 87 (27.4%), laparoscopic exploration: 22 (6.9%)]. The median age in the cohort was 69 years (range 60-75) and a majority had significant comorbidities with ASA-Score ≥ 3 (202/318, 63.5%). Statistically significant (p < 0.05) risk factors for non-resectability were age above 70 years (HR = 3.76, p = 0.003), portal vein embolization (PVE, HR = 5.73, p = 0.007), and arterial infiltration > 180° (HR = 8.05 p < 0.001) for technical non-resectability and PVE (HR = 4.67, p = 0.018), arterial infiltration > 180° (HR = 3.24, p = 0.015), and elevated CA 19-9 (HR = 3.2, p = 0.009) for oncological/liver-functional non-resectability. CONCLUSION: Advanced age, PVE, arterial infiltration, and elevated CA19-9 are major risk factors for non-resectability in pCCA. Preoperative assessment of those factors is crucial for better therapeutical pathways. Diagnostic laparoscopy, especially in high-risk situations, should be used to reduce the amount of explorative laparotomies without subsequent liver resection.

BACKGROUND/PURPOSE: This study compared the clinical efficacy and safety of laparoscopic versus open resection for hilar cholangiocarcinoma (HCCA) and analyzed potential prognostic factors. METHODS: The study included patients who underwent HCCA resection at our center from March 2012 to February 2022. Perioperative complications and postoperative prognosis were compared between the laparoscopic surgery (LS) and open surgery (OS) groups. RESULTS: After screening 313 HCCA patients, 68 patients were eligible for the study in the LS group (n = 40) and OS group (n = 28). Kaplan-Meier survival curve analysis revealed that overall survival > 2 years and 3-year disease-free survival (DFS) were more common in the LS than OS group, but the rate of 2-year DFS was lower in the LS group than OS group. Cox multivariate regression analysis revealed age (< 65 years), radical resection, and postoperative adjuvant therapy were associated with reduced risk of death (hazard ratio [HR] = 0.380, 95% confidence interval [CI] = 0.150-0.940, P = 0.036; HR = 0.080, 95% CI = 0.010-0.710, P = 0.024 and HR = 0.380, 95% CI = 0.150-0.960, P = 0.040), whereas preoperative biliary drainage was an independent factor associated with increased risk of death (HR = 2.810, 95% CI = 1.130-6.950, P = 0.026). Perineuronal invasion was identified as an independent risk factor affecting DFS (HR = 5.180, 95% CI = 1.170-22.960, P = 0.030). CONCLUSIONS: Compared with OS, laparoscopic HCCA resection does not significantly differ in terms of clinical efficacy. Age (<65 years), radical resection, and postoperative adjuvant therapy reduce the risk of death, and preoperative biliary drainage increases the risk of death.

BACKGROUND: Additional resection for invasive cancer at perihilar cholangiocarcinoma (pCCA) resection margins has become a consensus. However, controversy still exists regarding whether additional resection is necessary for residual biliary intraepithelial neoplasia (BilIN). METHOD: Consecutive patients with pCCA from two hospitals were enrolled. The incidence and pattern of resection margin BilIN were summarized. Prognosis between patients with negative margins (R0) and BilIN margins were analyzed. Cox regression with a forest plot was used to identify independent risk factors associated with overall survival (OS) and recurrence-free survival (RFS). Subgroup analysis was performed based on BilIN features and tumor characteristics. RESULTS: 306 pCCA patients receiving curative resection were included. 255 had R0 margins and 51 had BilIN margins. There was no significant difference in OS (P = 0.264) or RFS (P = 0.149) between the two group. Specifically, 19 patients with BilIN at distal bile ducts and 32 at proximal bile ducts. 42 patients showed low-grade BilIN, and 9 showed high-grade. Further analysis revealed no significant difference in long-term survival between different locations (P = 0.354), or between different grades (P = 0.772). Portal vein invasion, poor differentiation and lymph node metastasis were considered independent risk factors for OS and RFS, while BilIN was not. Subgroup analysis showed no significant difference in long-term survival between the lymph node metastasis subgroup, or between the portal vein invasion subgroup. CONCLUSION: For pCCA patients underwent curative resection, residual BilIN at resection margin is acceptable. Additional resection is not necessary for such patients to achieve absolute R0 margin.

BACKGROUND: Perihilar cholangiocarcinoma (phCCC) is a dismal malignancy. There is no consensus regarding the best treatment for patients with unresectable phCCC. The present review aimed to gather the current pieces of evidence for liver transplantation and liver resection as a treatment for phCCC and to build better guidance for clinical practice. DATA SOURCES: The search was conducted in PubMed, Embase, Cochrane, and LILACS. The related references were searched manually. Inclusion criteria were: reports in English or Portuguese literature that a) patients with confirmed diagnosis of phCCC; b) patients treated with a curative intent; c) patients with the outcomes of liver resection and liver transplantation. Case reports, reviews, letters, editorials, conference abstracts and papers with full-text unavailability were excluded from the analysis. RESULTS: Most of the current literature is based on observational retrospective studies with low grades of evidence. Liver resection has better long-term outcomes than systemic chemotherapy or palliation therapy and liver transplantation is a good alternative for selected patients with unresectable phCCC. All candidates for resection or transplantation should be medically fit and free of intrahepatic or extrahepatic diseases. As a general rule, patients presenting with a tumor having a longitudinal size > 3 cm or extending below the cystic duct, lymph node disease, confirmed extrahepatic dissemination; intraoperatively diagnosed metastatic disease; a history of other malignancies within the last five years, and did not complete chemoradiation regimen and were medically unfit should not be considered for transplantation. Some of these criteria should be individually assessed. Liver transplantation or resection should only be considered in highly experienced hepatobiliary centers, and any decision-making must be based on a multidisciplinary evaluation. CONCLUSIONS: phCCC is a complex condition with high morbidity. Surgical therapies, including hepatectomy and liver transplantation, are the best option for better long-term disease-free survival.

BACKGROUND AND STUDY AIMS: Laparoscopic approach of perihilar cholangiocarcinoma (PHC) is still challenging. We report the original use of a endoscopic hepaticogastrostomy (EHG) for definite biliary drainage in order to avoid biliary reconstruction. PATIENTS AND METHODS: A 70-year-old man presenting with jaundice was referred for resection of a Bismuth type IIIa PHC. Repeated endoscopic retrograde cholangiopancreatography failed to drain the future liver remnant, enabling only right anterior liver section drainage. EHG was performed three weeks before surgery. A hepatogastric anastomosis was created, placing a half-coated self-expanding endoprosthesis between biliary duct of segment 2 and the lesser gastric curvature. RESULTS: A laparoscopic right hepatectomy extended to segment 1, common bile duct, and hepatic pedicle lymphadenectomy was performed. The left hepatic duct was sectioned and ligated downstream to the biliary confluence of segment 2-3 and 4 allowing exclusive biliary flow through the EHG. The patient was disease free at 12 months, postoperative outcomes were uneventful except three readmissions for acute cholangitis due to prosthesis obstruction. CONCLUSIONS: EHG may be used as definite biliary drainage technique in laparoscopic PHC resection, at the expense of prosthesis obstruction and cholangitis.
