Combined hepatocellular-cholangiocarcinoma (cHCC-CCA) is a unique type of liver tumor that contains both hepatocellular carcinoma and cholangiocarcinoma components within a single tumor. The fifth edition of the World Health Organization classification provides a definition and diagnostic criteria for cHCC-CCA. However, the heterogeneous histomorphology and presentation resulting from variation of the proportion of each component poses challenges for clinical diagnosis and treatment. A diagnosis of cHCC-CCA may be suggested by the synchronous elevation of serum tumor markers for hepatocellular carcinoma and cholangiocarcinoma, a mixed enhancement pattern on imaging, and a discrepancy between the elevation of tumor marker and the imaging enhancement pattern...

INTRODUCTION AND IMPORTANCE: Colorectal cancer ranks as one of the most common cancer globally. About half of the patients experience a disease recurrence in the form of сolorectal cancer liver metastasis (CRLM) within the first 5 years of the course of the disease. However, there are rare cases of delayed onset of liver metastasis, that occur after cessation of standard follow-up. CASE PRESENTATION: A 38-year-old woman was referred to our institute with a metastatic liver mass adjacent to the liver hilum...

This paper provides insights into the conventional understanding of biliary tract malignancies, with a specific focus on cholangiocarcinoma (CCA). We then delve into the groundbreaking ideas presented by Dr. James Cleary. CCA, originating from biliary tree cells, manifests diverse subtypes contingent upon anatomical localization and differentiation status. These variants exhibit discrete genetic aberrations, yielding disparate clinical phenotypes and therapeutic modalities. Intrahepatic, perihilar, and distal CCAs intricately involve distinct segments of the biliary tree, further categorized as well-differentiated, moderately differentiated, or poorly differentiated adenocarcinomas based on their histological differentiation...

OBJECTIVE: To determine the impacts and outcomes of laparoscopic anatomic liver resection (LAR) and laparoscopic nonanatomic resection (LNAR) in patients with large hepatocellular carcinoma (HCC) in the right lobe of the liver. BACKGROUND: There are few comparative studies of LAR and LNAR for large HCC. METHOD: Three hundred thirty-seven patients underwent liver resection for large HCC (≥5 cm) at Seoul National University Bundang Hospital, Seoul, Korea, between January 2004 and December 2022...

BACKGROUND: Hepatic vein reconstruction (HVR) is occasionally necessary for resecting hepatic malignancies to ensure surgical margins while preserving remnant liver function [1]. Reports of multiple HVR are rare due to the highly technical demanding procedure and high risk of morbidity [2]. We introduce our procedure of double HVR for metastatic liver tumors invading the right hepatic vein (RHV) and middle hepatic vein (MHV). METHODS: The patient was a 66-year-old man with colorectal liver metastasis in segment 8, invading RHV and MHV...

BACKGROUND: In the era of innovating minimal invasive surgery, laparoscopic right posterior sectionectomy (RLPS) is considered a technically challenging procedure for its deeply anatomic location.1,2 Performed by experienced surgeons, it has been shown to be a safe and feasible procedure.3-6 The purpose of this video was to show the technique of a RLPS. METHODS: This is the case of a 70-year-old man who was treated for a mid-rectum adenocarcinoma with two synchronous liver metastases located in the posterior sector of the right liver...

PURPOSE: To simulate the advantages of anatomical resection, a new strategy of anatomical thermal ablation was proposed. The objective of this study was to evaluate the clinical value of anatomical thermal ablation (ATA) to treat subcapsular hepatocellular carcinoma by comparing it with anatomical resection (AR) and non-anatomical resection (NAR). METHODS: This retrospective cohort study enrolled hepatocellular carcinoma patients with subcapsular tumor diameter ≤ 50 mm treated by ATA or surgical resection at our center from October 2015 to December 2018...

Accurate minimally invasive anatomic liver (sub)segmentectomy (MIAS) is technically demanding and not yet standardized, and its surgical outcomes are undefined. To study the impact of the minimally invasive approach on perioperative outcomes of anatomic liver (sub)segmentectomy (AS), we retrospectively studied and compared perioperative outcomes of 99 open AS (OAS) and 112 MIAS (laparoscopic 77, robotic 35) cases using the extrahepatic Glissonean approach, based on the 1:1 propensity score matched analyses...

Many patients undergo small bowel and colon surgery for reasons related to malignancy, inflammatory bowel disease (IBD), mesenteric ischemia, and other benign conditions, including post-operative adhesions, hernias, trauma, volvulus, or diverticula. Some patients arrive in the operating theatre severely malnourished due to an underlying disease, while others develop complications (e.g., anastomotic leaks, abscesses, or strictures) that induce a systemic inflammatory response that can increase their energy and protein requirements...

BACKGROUND: Three-dimensional reconstructive visualization (3D-RVT) is an important tool in the preoperative assessment of patients undergoing liver resection. However, it is not clear whether this technique can improve short- and long-term outcomes in patients with hepatocellular carcinoma compared with two-dimensional (2D) imaging. METHOD: A total of 3402 patients from five centers were consecutively enrolled from January 2016 to December 2020, and grouped based on the use of 3D-RVT or 2D imaging for preoperative assessment...

BACKGROUND: To date, most laparoscopic anatomic bi-segmentectomy practices have been performed vertically, such as the resection of segments 6 and 7, segments 5 and 8, and segments 2 and 3;1-3 however, transversal hepatectomy may be more appropriate for certain lesions that are located in a specific area.4,5 Herein, we present a video of a pure laparoscopic anatomic bi-segmentectomy (S5 and S6) using Takasaki's approach and indocyanine green fluorescence navigation. METHOD: A 58-year-old male with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) was admitted to our institution...

Cholangiocarcinoma is a heterogeneous group of aggressive tumors that correspond to the second most common primary liver tumor. They can be classified according to their anatomical position concerning the biliary tree, and each subtype demonstrates different behavior and treatment. A 38-year-old male patient presenting solely right lumbar pain was diagnosed with a 7 cm hepatic tumor involving segments I, Iva, and VIII associated with involvement of the hepatic veins. He underwent a bloc resection of hepatic segments I, II, III, IV, partial V, partial VII, and VIII; right, middle, and left hepatic veins; and inferior vena cava segment, with perfusion of the remaining liver in situ with a preservation solution...

UNLABELLED: Purpose: To present a single-centre experience in bi- and uni-segmentectomies for primary liver tumours in children. METHODS: This study included 23 patients that underwent (bi)segmentectomy. There were 15 malignant tumours (hepatoblastoma-13 patients), 7 benign tumours, and 1 calcifying nested stromal epithelial tumour. RESULTS: The median tumour diameter was 52 mm (range 15-170 mm). Bisegmentectomy 2-3 was most frequently performed (seven patients), followed by bisegmentectomy 5-6 (four patients)...

BACKGROUND: Surgical resection for liver-only synchronous metastases of pancreatic ductal adenocarcinoma remains controversial. We investigated the role of conversion surgery in patients with a favorable response to systemic chemotherapy. METHODS: Patients (n=49) were diagnosed liver-only synchronous metastases using staging laparoscopy or open laparotomy between 2007 and 2022. Clinical outcomes were retrospectively compared among patients who underwent conversion surgery (n=10), upfront surgery with or without short-term neoadjuvant chemotherapy (UpS/short NAC) for oligometastases and occult metastases limited to the liver (n=8), and chemotherapy only for resectable or borderline resectable disease with occult liver-only metastases (n=31)...

The celiac trunk is the first branch of the abdominal aorta which arises from the anterior surface of the abdominal aorta and usually extends 1-2 cm before it branches into 3 branch arteries: the left gastric artery, the common hepatic artery, and the splenic artery. It is essential to comprehend the intricate arterial branch anatomy of the abdominal aorta to carry out abdominal surgeries as well as interventional radiology procedures safely. A 63-year-old woman who had been experiencing right upper quadrant adnominal pain for 2 months along with weight loss and appetite presented to the surgical unit of Tikur Ambessa Hospital...

Biliary tract cancers are molecularly and anatomically diverse cancers which include intrahepatic cholangiocarcinoma, extrahepatic (perihilar and distal) cholangiocarcinoma, and gallbladder cancer. While recognized as distinct entities, the rarer incidence of these cancers combined with diagnostic challenges in classifying anatomic origin has resulted in clinical trials and guideline recommended strategies being generalized patients with all types of biliary tract cancer. In this review, we delve into the unique aspects, subtype-specific clinical trial outcomes, and multidisciplinary management of patients with extrahepatic cholangiocarcinoma...

The shortage of deceased donor organs has prompted the development of alternative liver grafts for transplantation. Living-donor liver transplantation (LDLT) has emerged as a viable option, expanding the donor pool and enabling timely transplantation with favorable graft function and improved long-term outcomes. An accurate evaluation of the donor liver's volumetry (LV) and anatomical study is crucial to ensure adequate future liver remnant, graft volume and precise liver resection. Thus, ensuring donor safety and an appropriate graft-to-recipient weight ratio...
