PREVALENCE OF IATROGENIC PERFORATIONS ACCORDING TO THEIR LOCATION AND AFFECTED ROOT SURFACES

Iatrogenic perforations during colonoscopy.

The incidence of iatrogenic colonic perforations in the medical literature ranges between 0.005% and 0.63% with the majority of patients requiring laparotomy for repair. Colonoscopic perforation may occur due to several mechanisms: blunt trauma to the colonic wall, barotrauma from air insufflation, unintentional endoscopic resection or excessive thermal injury. Our clinical experience includes ...

Translation surfaces according to a new frame

In this paper we studied the translation surfaces according to a new frame called q-frame in three dimensional Euclidean space. The curvatures of the translation surface are obtained in terms of q-frame curvatures. Finally some special cases are investigated for these surfaces.

Incidence and Management of Iatrogenic Colonoscopic Perforations

nosis, treatment and follow-up of colorectal pathologies. However, this invasive procedure is performed with some risk of hemorrhage, perforation and even death. 2 The incidence of perforation is reported to range between 0.2% to 0.8% for diagnostic colonoscopy and from 0.15% to 3% for therapeutic colonoscopy. With increasing numbers of colonoscopies being performed for screening purposes, this...

Management of Idiopathic and Iatrogenic Esophageal Perforations.

DA Esophageal perforations can generally be classified as iatrogenic or idiopathic. Iatrogenic perforations are usually caused by gastroenterologists or surgeons performing endoscopy who inadvertently perforate the esophagus over the course of the procedure. Iatrogenic perforations can occur via a variety of other means, including when a nasogastric or feeding tube placement goes wrong or, less...
