Background/aims: The aim of this study was to evaluate the importance of concomitant caudate lobe resection in the course of major hepatectomy for hilar cholangiocarcinoma.
Methodology: During the period between January 1995 and December 2010, 159 patients were subjected to major hepatectomy with or without total caudate lobe resection at the Gastroenterology Centre, Mansoura University. These patients were divided in two groups: 1) a caudate lobe preservation (CLP) group (79 patients) and 2) a caudate lobe resection (CLR) group (80 patients). All patient data were retrospectively reviewed.
Results: This study included 94 men and 65 women with a mean age of 53.5±0 years without operative mortality. No differences were observed between groups regarding operative time, blood loss or the development of any individual postoperative complication. There were 23 (28.8%) margin-positive resections in the CLR group and 49 (62%) margin-positive resections in the CLP group (p≤0.001). Recurrence was confirmed in 53 (67.1%) and in 41(51.3%) patients in the CLP and CLR groups, respectively (p=0.031). The median survival of the CLR group was 36 months with a 5-year survival rate of 28%, while the median survival of the CLP group was 22 months with a 5-year survival rate of 5% (p≤0.001).
Conclusions: Caudate lobe resection in combination with major hepatectomy did not affect operative or postoperative morbidity and mortality. However, it led to higher rates of margin-negative resections and significantly improved survival.

Laparoscopic liver resection utilizing the ventral avascular area of the inferior vena cava: A retrospective cohort study.

Background: Laparoscopic liver resection (LLR) can be challenging due to the difficulty of establishing a retrohepatic tunnel under laparoscopy. Dissecting the third hepatic hilum before parenchymal transection often leads to significant liver mobilization, tumor compression, and bleeding from the short hepatic veins (SHVs). This study introduces a novel technique utilizing the ventral avascular area of the inferior vena cava (IVC), allowing SHVs to be addressed after parenchymal transection, thereby reducing surgical complexity and improving outcomes in in situ LLR.

Background: Laparoscopic anatomical liver resection has become more challenging because some subsegmental Glissonean pedicles are hard to dissect. Here, we introduce how to dissect every (sub) segmental Glissonean pedicle from the first porta hepatis and perform standardized (sub) segmentectomy [from segment 1 (S1) to S8].
Aim: To summarize our methods of laparoscopic anatomical segmental and subsegmental liver resection.

Background: Conventional right hepatectomy typically involves resection of the right hemiliver, often including partial removal of the caudate lobe. However, recent advancements, particularly in indocyanine green (ICG) fluorescence imaging, have allowed for more accurate identification of anatomical boundaries between liver segments. In this context, we present a refined technique for real anatomical right hepatectomy that preserves the caudate lobe, offering enhanced surgical precision and several distinct advantages over traditional methods.

Our study aimed to investigate the relationship between δ-catenin expression and whole-brain small-world network in breast cancer patients before chemotherapy using rs-fMRI. The study was based on the hypothesis that different δ-catenin expression levels correspond to distinct brain imaging characteristics. A total of 105 pathologically confirmed breast cancer patients were collected and categorized into high δ-catenin expression (DH, 52 cases) and low expression (DL, 53 cases) groups.

Living donor liver transplantation (LDLT) constitutes the majority of liver transplants in Asia and advancements in LDLT techniques have expanded the range of allografts beyond the commonly used right lobe (RL). This review provides a comprehensive overview of lesser-known variants of allografts and LDLT techniques which include right posterior sector grafts (RPSG), dual-lobe liver transplantation (DLLT), auxiliary partial orthotopic liver transplantation (APOLT), and extended left lobe grafts with caudate concentrating on the technical aspects, current evidence, and their indications in contemporary practice of LDLT. The first section examines RPSGs, focussing on their potential as an alternative to RL grafts particularly when volumetric studies indicate a larger right posterior sector in donors.
