Abstract Aim Robotic-assisted ventral hernia repair (rVHR) has become an attractive alternative to current laparoscopic and open procedures. The present study aims to determine short-and long-term complications following rVHR Material and Methods Patients undergoing rVHR from 01/01 2017 until 21/06 2020 were identified from the electronic medical record system. The medical case notes were reviewed and a telephone interview conducted to determine short and long-term complications. Patients with symptoms related to the repair were examined by a specialist in hernia surgery. US or CT scan was performed to determine the presence of absence of complications Results 85 patients were included. Mean age was 57.8 years, 54 were males (63.5%). Mean ASA-score was 2.12 and BMI was 30.2 kg/m2. 11 patients (13%) had diabetes, 22 (26%) were active smokers, 37 (44%) had hypertension and 7 (8%) were taking anti-coagulants. The mean hernial defect was 16.1 cm2 and the mesh size was 205.4 cm2. Mean length of stay was 0.5 days and the follow-up time was 94 weeks. Hematoma was encountered in 10 (11.8%) patients. 8 (9.4%) reported of seroma and 1 (1.2%) of a superficial wound infection complicated by skin necrosis. 5 patients (5.9%) reported of chronic pain. 2 patients (2.3%) developed recurrence. Conclusions The study demonstrates that rVHR is feasible and associated with few complications and a very low recurrence rate. Patients who had pain before surgery were likely to have less pain following the procedure. Due to the short hospital stay the procedure is suitable as an outpatient procedure.

According to the principle of magnetic flux leakage testing and the finite element numerical simulation, 3D finite element model (FEM) for MFL testing of tank bottom was established. Through simulative analysis, influence law between defect size and defect magnetic flux leakage field and the relationship curve of defect leakage magnetic field change with its size was obtained. The result showed that: When the length vary with sequence, the peak valley length of defects leakage magnetic signal increase with the increase of defect length, the relationship curve between each other is approximate linear; When the depth vary with sequence, the relationship between peak valley height of defects leakage magnetic signal and defect depth is also approximate linear, but this relationship was different with different length; When the width vary with sequence, on the defect symmetry plane, the peak of magnetic flux density along the width direction corresponded with the defect edge, and the length of the two peaks were equal to the width of the defect. According to simulation data and theory of regression analysis linear regression equation and relation surface between defect length depth and the characteristic quantity of its signal was established, quantitative method of defects signal was also proposed. Then experimental study was carried out in the Laboratory, the result show that the quantitative size was consistent with the actual defect size.

Abstract Aim “COVID has been a great challenge for Hospitals around the world. At our surgical department a new protocol of TAP block was designed and implemented in our laparoscopic incisional ventral hernia repairs, to allow these patients to be operated in ambulatory regime, without compromising pain control and the outcomes. In this video we aim to present the technique for the Laparoscopic-guided TAP Block during a Laparoscopic IPOM Plus ventral hernia repair.” Material and Methods “We implemented this protocol in July 2020 and since then, we performed 18 TAP block in laparoscopic incisional hernia repairs, laparoscopic guided by the Surgeon or ultrasound-guided by the Anesthesiologist. In this case, the video reports to a Laparoscopic IPOM Plus incisional hernia repair performed on a 54-year-old patient, male, with obesity, arterial hypertension and dyslipidemia. He had a 6 centimeter incisional hernia post-colorectal surgery in 2013.” Results “As detailed in the video, we show all the steps to perform a TAP block under laparoscopic direct visualization” Conclusions “TAP block can be performed by the Surgeon, with direct visualization at the beginning of the laparoscopic procedure.”

Composition of Trichiuridae and Gempylidae larvae (Teleostei) and their association with water masses in the Southwest Atlantic OceanIn this paper the relationship between temporal changes in the occurrence of water masses and Trichiuridae and Gempylidae larvae composition and distribution in the Southwest Atlantic ocean were analysed between 25° and 40° S. Ichthyoplankton was collected during the three expeditions of the Subtropical Convergence Project: Winter and Spring 1977, Autumn 1978 and Summer 1981, realized in the Southwest Atlantic waters. Oblique tows were conducted using a Hensen net with 250 μm mesh size. Steep salinity and temperature gradient were found, where the river outflows from La Plata river (Argentina) and Patos Lagoon (Brazil) met the Tropical Water over the continental shelf between 32 and 36° S. We examined 524 Hensen-net samples that contained about 283 larvae from five species of Trichiuridae and Gempylidae. The most abundant and frequent specie were

Background Morbid obesity is a serious chronic condition with, among other symptoms, increased intra-abdominal pressure and subsequent abdominal wall hernias. The optimal management of these manifestations is still controversial. The objective of this study was to assess the early postoperative outcomes of a surgical approach combining laparoscopic ventral hernia repair (LVHR) with sleeve gastrectomy in morbidly obese patients. Methods In this retrospective study, we reviewed the files of patients who are obese with a primary ventral hernia of less than 10 cm in diameter who received simultaneous laparoscopic sleeve gastrectomy and LVHR at our institution between February 2016 and July 2018. LVHR was performed using an intraperitoneal only mesh. The individual mesh size was chosen based on the number and size of the defects. Clinical and radiological follow-ups were performed between 9 and 15 months. Results A total of 15 patients were included. Five of them were males. The mean body mass index was 45.2 kg/m2 (range: 38.7–56.2 kg/m2). The mean hernia defect size was 2.6 cm (range: 1.3–4.2 cm). Mesh size was 10 × 15 cm in five, 20 × 15 cm in seven, and 25 cm× 20 cm in three patients. All patients were discharged without complications on the second postoperative day. Mean follow-up was at 12 months. One patient presented with hernia recurrence 14 months after surgery and four patients presented with self-limited seroma. Conclusion Despite ambiguous guidelines and ongoing debate regarding simultaneous bariatric surgery and ventral hernia repair, the short-term outcomes of this approach appeared promising, provided that patients are carefully selected and receive an individually tailored approach.
