Laparoscopic liver resection utilizing the ventral avascular area of the inferior vena cava: A retrospective cohort study.
World J Gastroenterol
January 2025
Department of Hepatobiliary Surgery, The First Affiliated Hospital of Chongqing Medical University, Chongqing 400000, China.
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.

Traditional methods involve the Nathanson retractor, associated with ischemia and necrosis complications. In addition, these techniques require an additional trocar with an incision that increases postoperative pain.

Introduction: Laennec's capsule serves as a critical anatomical landmark in anatomical liver resection. Despite its potential, a lack of large-scale prospective studies limits the widespread use of the Laennec approach for minimally invasive hepatectomy. This multicenter cohort study aimed to compare the outcomes of the traditional and Laennec approaches in minimally invasive anatomical hepatectomy across multiple centers in China.

Department of Digestive Surgery, Kawaguchi Municipal Medical Center, Kawaguchi City, Saitama, 180, Nishiaraijuku333-0833, Japan.
Background: Devices that help educate young doctors and enable safe, minimally invasive surgery are needed. Eureka is a surgical artificial intelligence (AI) system that can intraoperatively highlight loose connective tissues (LCTs) in the dissected layers and nerves in the surgical field displayed on a monitor. In this study, we examined whether AI navigation (AIN) with Eureka can assist trainees in recognizing nerves during colorectal surgery.

Int J Gynaecol Obstet
January 2025
FIGO, London, UK.
The incidence of cesarean section is dramatically increasing worldwide, whereas the training opportunities for obstetrician/gynecologists to manage complex cesarean section appear to be decreasing. This may be attributed to changing working hours directives and the increasing use of laparoscopy for gynecological surgical procedures, including in gynecological oncology. Various situations can create surgical difficulties during a cesarean section; however, two of the most frequent are complications from previous cesarean (myometrial defects, with or without placental intrusion and peritoneal adhesions) and the high risk of postpartum hemorrhage (uterine overdistension, abnormal placentation, uterine fibroids).
