We report the case of a 31-year old woman with recurrent cholangitis secondary to hepatolithiasis. The stones were composed of calcium bilirubinate. The patient also had a supernumerary hepatic lobe connected to the inferior aspect of the segment III of the liver. The role of the supernumerary hepatic lobe in the development of hepatolithiasis is unclear and may be coincidental.

Rationale: Peritoneal mucinous cystadenoma is rare in the clinic, lacks specific clinical manifestations, tumor markers, and imaging features, and is easily misdiagnosed and missed. Clinical practitioners should maintain a high level of vigilance. Here, we report a case of laparoscopic peritoneal mucinous cystadenoma stripping to improve our understanding of the disease.

Perivascular epithelioid cell tumors (PEComas) are a rare group of mesenchymal neoplasms composed of perivascular epithelioid cells. While commonly found in the kidney, uterus, and soft tissues, PEComas of the liver are exceedingly rare. We present a case of a PEComa incidentally discovered in a 73-year-old female patient undergoing evaluation for abdominal pain.

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: This study aimed to evaluate the immunotherapeutic effect of irreversible electroporation (IRE) and IP-001 in pancreatic adenocarcinoma with metastasis.
Methods: Orthotopic models of pancreatic adenocarcinoma with hepatic oligometastasis were established by implantation of tumor tissues (derived from Pan02 or KPC cells) size 2 mm into the pancreas and left liver lobe in C57BL/6J mice. One week after implantation, the tumor-burden mice were subjected to saline control, IRE, IP-001, and IRE+IP-001.

This case report highlights the diagnostic challenges in distinguishing between metastatic peritoneal mesothelioma with duodenal involvement and synovial sarcoma of the duodenum, two rare and complex entities. A 59-year-old woman presented with nonspecific abdominal symptoms, and imaging revealed a heterogeneous lesion between the right hepatic lobe and duodenum. Endoscopic ultrasound-guided biopsy and subsequent histopathological analysis initially suggested synovial sarcoma, but further examination, including a FISH assay, confirmed the diagnosis of malignant peritoneal mesothelioma.
