Iatrogenic duodenal perforation associated with endoscopic retrograde cholangiopancreatography (ERCP) is a very uncommon complication that is often lethal. Perforations during ERCP are caused by endoscopic sphincterotomy, placement of biliary or duodenal stents, guidewire-related causes, and endoscopy itself. In particular, perforation of the medial or lateral duodenal wall usually requires pro...

Fins are protrusions on a heat transfer surface to augment heat transfer rate from it. The increase in area exposed to convection in case of finned surfaces results in increased heat transfer rate. In this study heat transfer characteristics of a pin fin with perforation is numerically analyzed. A pin fin is fabricated and experiments are done under forced convection conditions. The experimenta...

Corticosteroids are used in the treatment of many rheumatological diseases including temporal arteritis. The gastrointestinal perforation during corticosteroid treatment is a serious complication. Colon perforation after steroid use was first reported by Beck et al in 1950.1 Although the pathophysiological mechanism is not understood clearly, it is claimed that steroids probably by disturbing t...

BACKGROUND Cardiac perforation is a feared complication of implantable cardioverter-defibrillator (ICD) lead implantation because of the potential for significant morbidity and mortality. Predictors of perforation and the severity of associated adverse events have not been well studied. We sought to identify predictors of cardiac perforation from ICD lead implantation and subsequent outcomes. ...

UNLABELLED Gastrointestinal perforation is a complication associated with steroid therapy or hypercortisolism, but it is rarely observed in patients with Cushing's disease in clinical practice, and only one case has been reported as a presenting symptom. Herein, we report a rare case of Cushing's disease in which a patient presented with gastrointestinal perforation as a symptom. A 79-year-old ...

Acute cholecystitis leading to gallbladder perforation is relatively common. However, transhepatic perforation of the gallbladder leading to biliary peritonitis is very rare. We present a rare case of biliary peritonitis caused by transhepatic perforation of the gallbladder.

BACKGROUND Colonic perforation is a rare complication associated with colonoscopy. There are no population-based studies on the risk of colonic perforation in IBD inpatients. AIM We sought to determine the prevalence of colonic perforation during colonoscopy among IBD inpatients, and to assess its risk factors. MATERIALS AND METHODS We obtained patient data from the Nationwide Inpatient Sam...

BACKGROUND The intrauterine device is a popular form of long-acting reversible contraception. Although generally safe, one of the most serious complications of intrauterine device use is uterine perforation. Risk factors for perforation include position of the uterus, force exerted during intrauterine device insertion, postpartum period, and breastfeeding. This case is important and needs to be...
