Laparoscopic radical and conservative surgery for hydatid liver echinococcosis: PSM based comparative analysis of immediate and long-term outcomes.

Background: The diffusion of laparoscopic radical surgery for hydatid liver echinococcosis remains limited. There are no published data on a comparative analysis of the immediate and long-term results of radical and conservative laparoscopic surgery for liver hydatid cysts. Comparison of the immediate and long-term outcomes after laparoscopic radical and conservative cystectomies was aimed.

A randomized prospective study of the immediate outcomes of the use of a hydro-jet dissector and an ultrasonic surgical aspirator for laparoscopic liver resection.

Background: No prospective randomized trials comparing transection techniques for the liver parenchyma transection during laparoscopic liver resection have been performed. The aim of the study was to compare the immediate outcomes of hydro-jet dissection with ultrasonic surgical aspirator in laparoscopic liver parenchyma transection in a prospective randomized single-center study.

Methods: Consecutive patients with liver benign and malignant tumors presenting to a single center from May 2017 to May 2020 were enrolled in the study.

Pancreas-preserving duodenal resections pancreatoduodenectomy for groove pancreatitis. Should we revisit treatment algorithm for groove pancreatitis?

Background: The management of cystic dystrophy of the duodenal wall (CDDW), or groove pancreatitis (GP), remains controversial. Although pancreatoduodenectomy (PD) is considered the most suitable operation for CDDW, pancreas-preserving duodenal resection (PPDR) has also been suggested as an alternative for the pure form of GP (isolated CDDW). There are no studies comparing PD and PPDR for this disease.

Combining E-PASS model and disease specific risk factors to predict severe morbidity after liver and bile duct resection for perihilar cholangiocarcinoma.

Background: Estimation of physiologic ability and surgical stress system (E-PASS) has been shown to be effective in predicting morbidity after surgery for perihilar cholangiocarcinoma (PHCC). Nevertheless, E-PASS does not include an assessment of the disease specific risk factors. The aim of the study was to estimate the combined impact of E-PASS and specific preoperative factors on major morbidity for PHCC patients.

Percutaneous radiofrequency-assisted liver partition versus portal vein embolization before hepatectomy for perihilar cholangiocarcinoma.

Background: Percutaneous radiofrequency-assisted liver partition with portal vein embolization in staged liver resection (PRALPPS) represents an alternative to portal vein embolization (PVE) followed by major liver resection in patients with perihilar cholangiocarcinoma.

Methods: This was an observational case-control study. Both procedures were applied in patients with a future liver remnant (FLR) volume of less than 40 per cent.
