Adult left lobe living donor liver transplantation has long been practiced nearly exclusively in Japan. To overcome the potential risks of small-for-size syndrome and hepatic venous outflow obstruction associated with the use of left lobe grafts, center-specific countermeasures such as splenectomy, meticulous hepatic venous reconstruction, and inclusion of the caudate lobe have been implemented, resulting in short- and long-term results comparable with those of right lobe graft in high-volume centers. A recent systematic review and meta-analysis confirmed these observations; however, the indications and techniques of adult left lobe living donor liver transplantation have yet to be standardized.

Background/Aims: The objective of this study was to evaluate the impact of the resected caudate lobe on survival, particularly in the context of anatomical resection of liver metastases in colorectal cancers without metastases in the caudate lobe. Materials and Methods: Patient data were extracted from the dataset titled "Preoperative CT and Survival Data for Patients Undergoing Resection of Colorectal Liver Metastases (CRLM)." The analysis specifically concentrated on individuals who underwent complete cau- date lobe resection in the absence of radiological signs of metastasis within the caudate lobe itself.

Point-of-care ultrasound in the diagnosis of hepatic gas gangrene.

Argentinian Critical Care Ultrasonography Association (ASARUC), Buenos Aires, Argentina.

Hepatic gas gangrene (HGG) is a rare but life-threatening condition typically caused by anaerobic bacteria such as Clostridium perfringens, though Gram-negative bacteria like Escherichia coli and Klebsiella species have also been implicated. Traditionally diagnosed via computed tomography (CT), point-of-care ultrasound (POCUS) has emerged as a valuable tool in critical care settings for its non-invasive, bedside utility. We report the case of a 51-year-old female with choledochal syndrome secondary to cholangiocarcinoma who developed HGG following left extended hepatectomy and biliary reconstruction.

: Resection of the caudate lobe of the liver is considered a highly challenging surgical procedure due to the deep anatomic location of this segment and the relationships with major vessels. There is no clear evidence about the safety and effectiveness of robotic resection of the caudate lobe. The aim of this systematic review was to report data about the safety, technical feasibility, and postoperative outcomes of robotic caudate lobectomy.

Perivascular epithelioid cell tumors (PEComas) belong to a family of rare mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid cells. Li-Fraumeni syndrome (LFS), an autosomal dominant cancer predisposition syndrome, is caused by a germline variant of the tumor suppressor gene TP53. Here, we report the case of a 20-year-old woman with LFS who developed a PEComa of the liver.
