Introduction: Laparoscopic Cholecystectomy (LC) and Intraperitoneal Onlay Meshplasty (IPOM) have established themselves as standard popular surgeries for gallstone disease ventral hernia, respectively. However, their concurrent performance co-existing hernia has never been studied. Aim: To determine the outcomes of LC IPOM in patients with hernia. Materials Methods: This retrospective observational study was conducted at Department General Surgery, Dr. L H Hiranandani Hospital, Mumbai, India...

Sometimes, during a laparoscopy, the operating surgeon may be confronted with an unexpected, previously undiagnosed secondary surgical condition. In such cases, if incidentally diagnosed condition warrants emergency therapy, must do it, albeit some modifications. Herein, authors describe patient gallstone disease who was taken up for laparoscopic cholecystectomy (LC). However, initial laparoscopy revealed complicated anterior diaphragmatic hernia. It duly repaired in same sitting,...

It to see small bowel obstruction due herniation intestine through adhesion between two adjacent AEs forming loop. We, herein, present case 64-year old male patient who had presented us with acute obstruction. During laparoscopy, culprit was found be an internal ileal loop AE sigmoid colon, were adherent at their tips. Laparoscopic transection tourniquet and excision performed, uneventful...

Multi-component gas diffusion in the continuum flow regime is often modelled using Stefan–Maxwell (SM) equations. Recent advances lattice Boltzmann (LB) mass models have made it possible to directly compare LB predictions with solutions SM In this work, one-dimensional (1D) and two-dimensional (2D), equi-molar counter-diffusion of two gases presence a third, inert studied. The work an extension validation recently proposed binary model for components having dissimilar molecular weights....

Our study explores the importance of early identification disease, probable etiopathogenesis, clinical and radiological features a treatment protocol for Associated Fungal Osteomyelitis Jaws Sinuses (CAFOJS). A one-year prospective from June 2020 to May 2021 was conducted among CAFOJS diagnosed patients tertiary care center in South India. Demographic details, infection history, time taken...

Recently, there has been a great deal of interest in extending the lattice Boltzmann method (LBM) to model transport phenomena non-continuum regime. Most these studies have focused on single-component flows through simple geometries.

Abstract The solid oxide fuel cell (SOFC) allows the conversion of chemical energy that is stored in a given fuel, including light hydrocarbons, to electrical power. Hydrocarbon fuels, such as methane, are logistically favourable and provide high densities. However, use these fuels often results decreased efficiency life. An improved understanding reactive flow SOFC anode can help address issues. In this study, transport heterogeneous internal reformation methane based addressed. effect...
