Anatomical Schemata Revealed by the Critical View of Safety Approach: A Proposal of the Hellenic Task Force on the Typology of Safe Laparoscopic Cholecystectomy (HETALCHO).

: Laparoscopic cholecystectomy (LC) is the most commonly performed operation in general surgery in the Western World. Gallbladder surgery, although most of the time simple, always offers the possibility of unpleasant surprises. Despite progress, the incidence of common bile duct injury is 0.

Oncological resection and perioperative outcomes of robotic, laparoscopic and open pancreatoduodenectomy for ampullary adenocarcinoma: a propensity score matched international multicenter cohort study.

Background: Ampullary adenocarcinoma (AAC) typically presents at an early stage due to biliary obstruction and therefore might be specifically suitable for minimally invasive pancreatoduodenectomy (MIPD). However, studies assessing MIPD specifically for AAC, including the robotic and laparoscopic approach, are limited. The aim of this study is to compare short- and long-term oncological resection and perioperative outcomes of robotic (RPD), laparoscopic (LPD) and open pancreatoduodenectomy (OPD) performed specifically for AAC.

Malignant Peripheral Nerve Sheath Tumor of the Small Bowel: A Case Report and Review of the Literature.

Malignant peripheral nerve sheath tumor (MPNST) is an uncommon type of sarcoma that arises from a peripheral nerve or any tissue with nerve sheath differentiation. It does not have any specific symptoms and shows great variability in clinical and radiological findings. It is usually associated with neurofibromatosis type 1 (NF1).

Aberrant anatomy in the context of the critical view of safety.

Background: The protective impact of the Critical View of Safety (CVS) approach on the vasculo-biliary injuries during laparoscopic cholecystectomy (LC) depends largely upon the understanding of the normal and variant anatomy. Structures exposed during the acquisition of the CVS can deviate from the typical dual configuration of the cystic duct and artery (gallbladder pedicle) representing either a third (supernumerary) or atypical in course (heterotopic) element. The aim of this study was to determine the identity and the frequency of these anatomical elements and to propose anatomic schemata that can guide the achievement of CVS by surgeons.

Efficacy of atezolizumab-bevacizumab combination therapy early after recurrence of hepatocellular carcinoma following resection or ablation with a curative intent.

Background: The pattern of hepatocellular carcinoma (HCC) recurrence after resection/ablation is intrahepatic and/or systemic. The efficacy of atezolizumab-bevacizumab treatment as early therapy after recurrence has not been extensively evaluated.

Methods: We evaluated 32 patients (group A) with early HCC recurrence after resection/ablation and 24 patients (group B) initially diagnosed as Barcelona Clinic Liver Cancer (BCLC)-C, all treated with atezolizumab-bevacizumab.
