Retroperitoneal-first dissection approach at the dorsal space for a huge serous cystic neoplasm of the pancreatic tail: a case report.

Background: Large tumors of serous cystic adenomas in the pancreatic body-to-tail severely compress the surrounding organs and retroperitoneal space.

Case Presentation: We present a unique surgical challenge for distal pancreatectomy (DP). We present the case of a patient who had a massive mass lesion measuring more than 20 cm in size that had been misdiagnosed as a retroperitoneal tumor by the previous hospital.

Prognostic Value of Repeat Hepatectomy for Hepatocellular Carcinoma Patients.

Background/aim: The potential for repeat hepatectomy has been increasing in hepatocellular carcinoma (HCC) patients.

Patients And Methods: To assess its significance, we examined the clinical features, surgical records, and survival of 279 HCC patients who underwent hepatectomy as primary treatment. Patients were divided into three groups: single hepatectomy without HCC relapse in 97 patients (Group 1), single hepatectomy with HCC relapse in 133 patients (Group 2) and repeat hepatectomy for HCC relapse in 49 patients (Group 3).

Relationship of immunonutritional factor with changes in liver volume after portal vein embolization.

Background: To identify predictors of changes in hepatic volumes after portal vein embolization, we examined the relationship with preoperative nutritional and immunological parameters.

Patients And Methods: Ninety-three patients who underwent portal vein embolization were included. The control group comprised 13 patients who underwent right hepatectomy without portal vein embolization.
