The increasing use of laparoscopic cholecystectomy has led to an increased frequency of gallbladder perforation and subsequent gallstone spillage in the abdominal cavity. Occasionally unretrieved gallstones can cause infection, adhesions, and obstruction. Furthermore, spilt stones can cause erosion into adjacent organs and can migrate to distant sites, causing a variety of complications. We rep...

Spontaneous perforation of the bile duct without traumatic or iatrogenic injury is extremely rare. It is very difficult to diagnose, before surgical exploration (1). We report a case of abscess formation related to spontaneous perforation of the common bile duct (CBD) by gallstones, which presented as a choledochal cyst on computed tomography (CT). A diagnosis of spontaneous CBD perforation and...

We report a case of a 57-year-old woman who presented with a necrotizing soft tissue infection of the right anterior abdominal wall, 1 year after open cholecystectomy for gallbladder perforation. Surgical exploration revealed pigmented gallstones along with pus in the abdominal wall and gallbladder fossa. Intraoperative spillage of gallstones is common during both open and laparoscopic cholecys...

Wind power generation is variable and uncertain. In the power systems with high penetration of wind power, determination of equivalent operating reserve is the main concern of systems operator. In this paper, a model is proposed to determine operating reserves in simultaneous market clearing of energy and reserve by stochastic programming based on scenarios generated via Monte Carlo simulation ...

Renewable energy sources (RESs) have a remarkable role in advancing the goals of restructured power systems to reduce greenhouse gas emissions and increase level reliability. However, due non-uniform utilisation these resources various sectors grids, major part generated renewable energies is spilled satisfy system constraints. Motivated by this challenge, reconfiguration mechanism maximising R...

This paper introduces an ongoing EU research project called EU-MOP, which involves the design and evaluation of an intelligent and efficient robot system to respond to oil spills. The EU-MOP project addresses both unit and system level (i.e. unit design and emergency response topics) so as to draft a complete proposal/solution regarding oil spillage. The paper defines the objectives of the proj...

Objective: The main objective was to determine the complications of laparoscopic cholecystectomy (LC) and its causes at Isra University Hospital, Hyderabad. Methodology: This was a retrospective study carried out from July 2005 to June 2007. Data of all patients undergoing laparoscopic cholecystectomy during the study period and fulfilling the selection criteria was collected and analyzed retro...

Experienced laparoscopic surgeons should consider laparoscopy as an alternative to laparotomy in management of ovarian dermoid cysts in selected cases. The aim of this study was to analyze the safety of laparoscopy in ovarian dermoid cysts treatment and risk of chemical peritonitis. We report 63 cases of patients (mean age of 37) with ovarian dermoid cysts originating from the ovary, treated fr...
