Background: Patients' need to improve outcomes and to reduce the number of complications triggers the development of new materials and surgery concepts. Currently, there are many implants and fixation systems dedicated for intraperitoneal onlay mesh procedure. The aim of this study was to compare two different mesh/fixation system concepts (PH: Physiomesh/Securestrap and VS: Ventralight ST/SorbaFix) for laparoscopic ventral hernia repair with respect to pain.
Methods: A single-center, prospective, randomized study was designed to include 50 patients per group with a planned interim analysis for safety after 25 patients. The endpoints were pain occurrences and intensity, which was measured with the visual analogue scale 7 days, 30 days, 3 months and 6 months after surgery. The safety parameters included the number of recurrences and postoperative complications.
Results: During the interim analysis, the study was stopped due to safety reasons. We observed five (20 %) recurrences in the PH group in first 6 months and none in the VS group. We observed a significantly higher pain rate in the PH group after 3 months (p < 0.0001) and no difference after 7 days (p = 0. 7019). The pain intensity decreased significantly over time (p < 0.0001) and was significantly higher in the PH group (p < 0.0001).
Conclusions: Although this clinical trial was terminated prior to the preplanned recruitment goal, the obtained results from the enrolled patients indicate that the PH system associated with significantly greater hernia recurrences and postoperative pain compared with the VS system. This confirms the superiority of the elastic mesh concept, which may be a safer and more efficacious option for laparoscopic ventral hernia repairs.

Laparoscopic liver resection utilizing the ventral avascular area of the inferior vena cava: A retrospective cohort study.

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.

Spigelian hernia and cryptorchidism syndrome in children is increasingly reported in the literature. A variety of phenotypes have been reported, so diagnostic approaches and operative techniques remain poorly defined. The case of an infant male who presented with a left spigelian hernia and ipsilateral cryptorchidism who was initially misdiagnosed with an ectopic inguinal testis is presented.

Introduction: The last decade has witnessed several modifications in the laparoscopic techniques for ventral hernia. The aim of this study was to compare an established repair such as laparoscopic intraperitoneal onlay mesh repair with defect closure (IPOM plus) with subcutaneous onlay endoscopic approach (SCOLA) for medium ventral hernia.
Patients And Methods: From June 2019 to November 2021, 29 patients undergoing IPOM plus and 22 patients undergoing SCOLA for medium ventral hernia (umbilical and epigastric hernia of size 2-4 cm) were included in the study.
