Parenchyma-preserving hepatectomy including segments I + IV resection and bile duct resection in a patient with type IV perihilar cholangiocarcinoma: A case report with video clip.

ABSTRACT: It has been reported that parenchyma-preserving hepatectomy (PPH) might lower surgical curability with an increased likelihood of bile duct resection margins (BDRMs). Apparently, PPH is indicated for patients expected to achieve curative resection. The author herein presents a case of a 77-year-old male patient with type IV perihilar cholangiocarcinoma and decreased cardiac function treated with hepatic segments I + IV resection and bile duct resection. During the operation, he underwent two hepatic parenchymal transections matched with right trisectionectomy and left hepatectomy. After removing segments VI and I and extrahepatic bile duct, six hepatic duct openings were exposed at the left and right hila. As some of them were conjoined, two hepaticojejunostomies at the right liver and one hepaticojejunostomy at the left lateral section were performed consecutively. This operation took 7 hours. Eight sessions of intraoperative frozen-section biopsy were performed. All BDRMs were tumor-negative. According to the 8th edition of the American Joint Committee on Cancer staging system, the extent of the tumor was pT2bN2M0. It was regarded as stage IVA tumor. The patient recovered uneventfully. He was discharged on the 18th postoperative day. The patient underwent concurrent chemoradiation therapy and adjuvant chemotherapy. The patient has been doing well without tumor recurrence for the past 24 months to date. In conclusion, PPH can lead to curative resection and improved outcomes through reasonable adjustment of the extent of hepatectomy.

Project description:Open surgery is the standard of care for perihilar cholangiocarcinoma (pCCA). With the aim of oncologic radicality, it requires a complex major hepatectomy with biliary reconstruction. The postoperative course is consequently often complicated, with severe morbidity and mortality rates of up to 27.5-54% and 18%, respectively. Robotic liver surgery is emerging as a safe, minimally-invasive technique with huge potential for pCCA management. After the first case described by Giulianotti in 2010, here we present the first western series of robot-assisted liver resections with biliary reconstruction for pCCA with the aim to preliminarily assess the feasibility and repeatability of the procedure. At our high-volume teaching hospital center dedicated to HPB surgery, 128 pCCA patients have been surgically treated in the last 15 years whereas more than 800 laparoscopic liver resections have been performed. Since the Da Vinci Xi Robotic platform was introduced in late 2018, 6 major robotic liver resections with biliary reconstruction have been performed, 4 of which were for pCCA. All 4 cases involved a left hepatectomy with caudate lobectomy. The median operating time was 840 min, with a median blood loss of 700 ml. One case was converted to open surgery during the reconstruction due to a short mesentery preventing the hepatico-jejunostomy. None of the patients experienced major complications, while minor complications occurred in 3 out of 4 cases. One biliary leak was managed conservatively. The median postoperative stay was 9 days. Negative biliary margins were achieved in 3 of the 4 cases. An included video clip shows the most relevant technical details. This preliminary series demonstrates that robot-assisted liver resection for pCCA is feasible. We speculate that the da Vinci platform has a relevant potential in pCCA surgery with particular reference to the multi-duct biliary reconstruction. Further studies are needed to better clarify the role of this high-cost technology in the minimally-invasive treatment of pCCA.

Project description:ObjectiveTo evaluate the effect of vascular resection (VR), including portal vein resection (PVR) and hepatic artery resection (HAR), on short- and long-term outcomes in patients with perihilar cholangiocarcinoma (PHC).BackgroundResection surgery and transplantation are the main treatment methods for PHC that provide a chance of long-term survival. However, the efficacy and safety of VR, including PVR and HAR, for treating PHC remain controversial.MethodsThis study was registered at the International Prospective Register of Systematic Reviews (CRD42020223330). The EMBASE, PubMed, and Cochrane Library databases were used to search for eligible studies published through November 28, 2020. Studies comparing short- and long-term outcomes between patients who underwent hepatectomy with or without PVR and/or HAR were included. Random- and fixed-effects models were applied to assess the outcomes, including morbidity, mortality, and R0 resection rate, as well as the impact of PVR and HAR on long-term survival.ResultsTwenty-two studies including 4,091 patients were deemed eligible and included in this study. The meta-analysis showed that PVR did not increase the postoperative morbidity rate (odds ratio (OR): 1.03, 95% confidenceinterval (CI): [0.74-1.42], P = 0.88) and slightly increased the postoperative mortality rate (OR: 1.61, 95% CI [1.02-2.54], P = 0.04). HAR did not increase the postoperative morbidity rate (OR: 1.32, 95% CI [0.83-2.11], P = 0.24) and significantly increased the postoperative mortality rate (OR: 4.20, 95% CI [1.88-9.39], P = 0.0005). Neither PVR nor HAR improved the R0 resection rate (OR: 0.70, 95% CI [0.47-1.03], P = 0.07; OR: 0.77, 95% CI [0.37-1.61], P = 0.49, respectively) or long-term survival (OR: 0.52, 95% CI [0.35-0.76], P = 0.0008; OR: 0.43, 95% CI [0.32-0.57], P < 0.00001, respectively).ConclusionsPVR is relatively safe and might benefit certain patients with advanced PHC in terms of long-term survival, but it is not routinely recommended. HAR results in a higher mortality rate and lower overall survival rate, with no proven benefit.
