Short-term outcomes after liver resection with vascular reconstruction: Results from a study with the National Clinical Database of Japan. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2024. [PMID: 38679741 DOI: 10.1002/jhbp.1435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 03/15/2024] [Accepted: 03/22/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND Although curative resection with vascular reconstruction improves the prognosis of blood-invading locally advanced hepatobiliary tumors, the mortality and morbidity of the procedure remains unclear. This study aimed to clarify the risk factors associated with mortality and morbidity in patients undergoing liver resection with vascular reconstruction. METHODS This retrospective observational study included 1215 patients undergoing hepatectomy of more than one section with vascular reconstruction, except for left lateral sectionectomy registered in the National Clinical Database (NCD) between 2015 and 2019. The rates of surgical mortality and relevant clinical factors were evaluated. RESULTS Among the four types of vascular reconstruction, portal venous reconstruction was frequently performed in 724 patients (59.6% of the enrolled patients). Surgical mortality was 8.1%. Patients with hepatic artery reconstruction had the highest surgical mortality rate of 15.8%. In other types of reconstruction, surgical mortality was 9.1% in the portal vein, 5.2% in inferior vena cava, and 4.9% in hepatic vein. Factors significantly associated with surgical mortality include age, sex (male), preoperative comorbidity (American Society of Anesthesiologists grade >3, respiratory distress, diabetes, preoperative pneumonia, weight loss, and obstructive jaundice), poorer liver functional reserve (indocyanine green retention rate at 15 min and prothrombin time/international normalized ratio >1.1) and accompanying biliary reconstruction. CONCLUSIONS The NCD revealed the detailed status of liver resection combined with vascular reconstruction in Japan. Based on the results of this analysis, understanding the factors that influence the outcome and postoperative course of each procedure will provide patients with accurate information and opportunities to improve future outcomes.

Novel choledochojejunostomy technique "T-shaped anastomosis" for preventing the development of postoperative cholangitis in pancreatoduodenectomy: A propensity score matching analysis. Ann Gastroenterol Surg 2024; 8:301-311. [PMID: 38455496 PMCID: PMC10914695 DOI: 10.1002/ags3.12744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2023] [Revised: 09/06/2023] [Accepted: 09/12/2023] [Indexed: 03/09/2024] Open
Abstract
Background There have been few studies of countermeasures against postoperative cholangitis, a serious complication after pancreaticoduodenectomy (PD) that impairs quality of life. Objective To evaluate our recently developed, novel method of choledochojejunostomy with a larger anastomotic diameter, the "T-shaped anastomosis." Methods The study included 261 cases of PD. The T-shaped choledochojejunostomy technique was performed with an additional incision for a distance greater than half the diameter of the bile duct at the anterior wall of the bile duct and the anterior wall of the elevated jejunum. To compensate for potential confounding biases between the standard anastomosis group (n = 206) and the T-shaped anastomosis group (n = 55), we performed propensity score matching (PSM). The primary endpoint was the incidence of medium-term postoperative cholangitis adjusted for PSM. Results In the PSM analysis, 54 patients in each group were matched, and the median bile duct diameter measured by preoperative CT was 8.8 mm versus 9.3 mm, the rate of preoperative biliary drainage was 31% versus 37%, the incidence of cholangitis within 1 month before surgery was 9% versus 13%, and the incidence of postoperative bile leakage was 2% versus 2%, with no significant differences. The incidence of medium-term postoperative cholangitis was 15% versus 4%, and multivariate logistic regression revealed that T-shaped choledochojejunostomy was an independent predictor of a reduced incidence of cholangitis (odds ratio, 0.17, 95% CI 0.02-0.81; p = 0.024). Conclusions The T-shaped choledochojejunostomy technique was shown to be effective with a significant reduction in the incidence of medium-term postoperative cholangitis. Clinical trial identification: UMIN000050990.

Impact of the COVID-19 pandemic on the number and short-term outcomes in hepatectomy for hepatocellular carcinoma: Results from the Japanese National Clinical Database, 2018-2021. Hepatol Res 2024. [PMID: 38308614 DOI: 10.1111/hepr.14014] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 12/23/2023] [Accepted: 01/08/2024] [Indexed: 02/05/2024]
Abstract
AIM The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the allocation of medical resources, including cancer screening, diagnosis, and treatment. We aimed to investigate the effects of the pandemic on morbidity and mortality following hepatectomy for hepatocellular carcinoma (HCC). METHODS We identified patients who underwent hepatectomy for HCC between 2018 and 2021 from the Japanese National Clinical Database (NCD). The number of surgical cases, the use of intensive care units, and the incidence of morbidity were assessed. The standardized morbidity / mortality ratio (SMR) was used to evaluate the rates of morbidity (bile leakage and pneumonia) and mortality in each month, which compares the observed incidence to the expected incidence calculated by the NCD's risk calculator. RESULTS The study included a total of 10 647 cases. The number of patients undergoing hepatectomy for HCC gradually decreased. The proportion of patients aged 80 years or older increased and that of cases with T1 stage decreased. The proportion of patients who were admitted to the intensive care unit did not change between the pre- and postpandemic period. The mean actual incidence rates of bile leakage, pneumonia, 30-day mortality, and surgical mortality were 9.2%, 2.3%, 1.4%, and 2.1%, respectively. The SMR for the mortalities and morbidities in each month did not increase mostly throughout the COVID-19 pandemic. CONCLUSIONS The present study showed the decreasing number of resected cases for HCC, while the surgical safety for hepatectomy was enough to be maintained by managing medical resources in Japan.

Abstract
Background The principle of hepatoblastoma (HB) treatment is complete resection. The removal of tumor-bearing section(s) or hemiliver is widely accepted. However, neither the standardized anterior approach for right hepatectomy nor parenchymal sparing anatomical liver resection has been described for HB. Methods We retrospectively reviewed the clinical course of two pediatric HB patients who underwent extended right hepatectomy using the anterior approach with the liver hanging maneuver and one who underwent parenchymal sparing anatomical liver resection of S4 apical+S8 ventral/dorsal+S7. The critical aspects of surgical techniques are described in detail. Results In all three patients, R0 resection was achieved without complications and are currently alive without recurrence after an average follow-up of 23 months. Intraoperative cardiac hemodynamics were stable, even in a trisomy 18 patient with cardiac disease. Conclusions Our findings suggest that these innovative techniques established in adults are safe and feasible for HB in children. These techniques also allow optimal anatomical liver resection to accomplish curative surgery while maintaining the functional reserve of the remnant liver.

Perioperative predictive factors of failure to rescue following highly advanced hepatobiliary-pancreatic surgery: a single-institution retrospective study. World J Surg Oncol 2023; 21:365.

Abstract
BACKGROUND Failure to rescue (FTR), defined as a postoperative complication leading to death, is a recently described outcome metric used to evaluate treatment quality. However, the predictive factors for FTR, particularly following highly advanced hepatobiliary-pancreatic surgery (HBPS), have not been adequately investigated. This study aimed to identify perioperative predictive factors for FTR following highly advanced HBPS. METHODS This single-institution retrospective study involved 177 patients at Gifu University Hospital, Japan, who developed severe postoperative complications (Clavien-Dindo classification grades ≥ III) between 2010 and 2022 following highly advanced HBPS. Univariate analysis was used to identify pre-, intra-, and postoperative risks of FTR. RESULTS Nine postoperative mortalities occurred during the study period (overall mortality rate, 1.3% [9/686]; FTR rate, 5.1% [9/177]). Univariate analysis indicated that comorbid liver disease, intraoperative blood loss, intraoperative blood transfusion, postoperative liver failure, postoperative respiratory failure, and postoperative bleeding significantly correlated with FTR. CONCLUSIONS FTR was found to be associated with perioperative factors. Well-coordinated surgical procedures to avoid intra- and postoperative bleeding and unnecessary blood transfusions, as well as postoperative team management with attention to the occurrence of organ failure, may decrease FTR rates.

Abstract
BACKGROUND The current high-level hepatectomy (HLH) is certified by the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHBPS), comprising only anatomical hepatectomies above Couinaud's segmentectomy. This multicenter study aimed to identify the conditions of non-HLH that satisfy equivalent technical difficulties to HLH. METHODS Between 2018 and 2021, 595 first open hepatectomies without biliary reconstruction (374 HLHs and 221 non-HLHs) were performed in the five institutions. Non-HLHs belonging to at least one of the three conditions; depth of hepatectomy ≥5 cm, number of resections ≥3 locations and at least one location with a depth of hepatectomy ≥3 cm, and hepatectomy involving the paracaval portion of the caudate lobe was proposed as the candidate for difficult non-HLH. The technical difficulty was estimated by the operative time and blood loss. RESULTS Difficult non-HLHs were neither associated with shorter operative time (373 min vs. 354 min, p = .184) nor lesser blood loss than those with HLHs (503 mL vs. 436 mL, p = .126). Postoperative complications such as Clavien-Dindo classification grade III or more were not significant between the two groups (18.6% vs. 13.4%, p = 0212). CONCLUSIONS Difficult non-HLHs were associated with no lesser technical difficulty than those with HLH.

Abstract
Resection is the only potential curative treatment for perihilar cholangiocarcinoma (PHC); however, complete resection is often technically challenging due to the anatomical location. Various innovative approaches and procedures were invented to circumvent this limitation but the rates of postoperative morbidity (20%-78%) and mortality (2%-15%) are still high. In patients diagnosed with resectable PHC, deliberate and coordinated preoperative workup and optimization of the patient and future liver remnant are crucial. Biliary drainage is recommended to relieve obstructive jaundice and optimize the clinical condition before liver resection. Biliary drainage for PHC can be performed either by endoscopic biliary drainage or percutaneous transhepatic biliary drainage. To date there is no consensus about which method is preferred. The volumetric assessment of the future remnant liver volume and optimization mainly using portal vein embolization is the gold standard in the management of the risk to develop post hepatectomy liver failure. The improvement of systemic chemotherapy has contributed to prolong the survival not only in patients with unresectable PHC but also in patients undergoing curative surgery. In this article, we review the literature and discuss the current surgical treatment of PHC.

Abstract
BACKGROUND Calcitonin-producing pancreatic neuroendocrine neoplasms (PanNENs) are extremely rare. There have been no reports of a patient in whom liver metastases were the presenting finding, and a calcitonin-producing PanNEN was subsequently detected after a lengthy period. CASE PRESENTATION A 53-year-old man had diarrhea for several years. Computed tomography (CT) revealed multiple liver tumors. We performed a left trisectionectomy with a bile duct resection. The histologic examination showed neuroendocrine tumors G1. Immunohistochemistry was positive for calcitonin and the serum calcitonin level was elevated. Neuroendocrine neoplasms of hepatic origin are extremely rare, so a systemic exploration was performed, but no tumor was detected. CT showed a 4-mm calcification in the pancreatic body, but no contrast-enhanced mass was noted. Although the liver tumors were resected, the diarrhea and high serum calcitonin level persisted. Serial examinations were performed for 6 years, but no tumor was identified; however, 6.5 years after the hepatectomy the serum calcitonin level increased. CT showed a 10-mm contrast-enhanced mass in the calcified area of the pancreatic body. A distal pancreatectomy was performed. The histologic examination showed a neuroendocrine tumor G1, which mimicked the liver tumors. Immunohistochemistry was positive for calcitonin. After the distal pancreatectomy, the serum calcitonin level decreased and diarrhea resolved. The calcitonin-producing neuroendocrine neoplasm was considered the pancreatic primary and the hepatic tumors were metastases. CONCLUSIONS Calcitonin-producing PanNENs may be initially recognized as liver tumors and may become evident after a lengthy period, thus long-term observation is recommended. Aggressive surgeries may contribute to long-term survival.
