The purpose of this study is to validate a Jacobian-based iterative method for real-time localization of magnetically controlled endoscopic capsules. The proposed approach applies finite-element solutions to the magnetic field problem and least-squares interpolations to obtain closed-form and fast estimates of the magnetic field. By defining a closed-form expression for the Jacobian of the magnetic field relative to changes in the capsule pose, we are able to obtain an iterative localization at a faster computational time when compared with prior works, without suffering from the inaccuracies stemming from dipole assumptions...

BACKGROUND AND AIMS: There a shortage of robust information about profiles of gastrointestinal disease in sub-Saharan Africa. The endoscopy unit of the University Teaching Hospital in Lusaka has been running without interruption since 1977 and this 38-year record is largely intact. We report an analysis of endoscopic findings over this period. METHODS: Written endoscopy records from 29th September 1977 to 16th December 2014 were recovered, computerised, coded by two experienced endoscopists and analysed...

We present a 74-year-old woman, who developed massive haematemesis and hypovolaemic shock. Her management was challenging, as the bleeding site could not be identified during oesophagogastroduodenoscopy, she was not fit for a general anaesthesia and not able to lie flat due to heart failure, caused by pericardial effusion. She underwent an emergency laparotomy and gastrotomy under a combined thoracic epidural and lumbar spinal regional anaesthesia in a sitting position, 45° to horizontal plane. The bleeding site was identified as a Dieulafoy lesion on the posterior wall of the stomach and was controlled by under running the lesion...

In spite of the economic development through the past six decades post-independence, nearly 70% of the Indian population still live in villages, and these people very often have limited access to the advanced health-care technology. In an attempt to render cost-effective gastrointestinal care to the rural dwellers, we have initiated a Rural Health Care Project. We have tailor-made and converted a bus into a mobile hospital equipped with basic diagnostic facilities including a custom-made endoscopy unit. This bus travels to rural areas and renders basic diagnostic and therapeutic services including endoscopy...

We investigated the microbial contamination of suction tubes attached to wall-type suction instruments. Microbial contamination of suction tubes used for endoscopy or sputum suction in hospital wards was examined before and after their disinfection. In addition, disinfection and washing methods for suction tubes were evaluated. Suction tubes (n=33) before disinfection were contaminated with 10(2)-10(8) colony-forming units (cfu)/tube. The main contaminants were Pseudomonas aeruginosa, Acinetobacter baumannii, and Stenotrophomonas maltophilia...

AIM: The increase in the average life led an increase of diseases, acute and chronic, not only cardiovascular and respiratory system, but also gastrointestinal. Likewise we see an increase in neoplastic lesions, sometimes diagnosed in advanced stage of disease, not susceptible to radical therapy. The purpose of this work is to evaluate the usefulness, reliability and security of colonoscopy in elderly patients, age 75 years or more. MATHERIALS END METHODS: We analysed 2407 colonoscopies, performed from January 2005 to December 2006 in Unit of Digestive Endoscopy of Gastrointestinal Surgery ("Federico II" University of Naples) and in Unit of Digestive Endoscopy of "Villa Maria Clinica" (Mirabella Eclano)...

BACKGROUND: Autopsy studies confirm that many intensive care unit (ICU) patients die from unrecognized sources of abdominal sepsis or ischemia. Computed tomography (CT) scans can be of limited use for these diagnoses and difficult to obtain in critically ill patients who require significant support for transport. Bedside laparoscopy has been described but still is cumbersome to perform. Bedside flexible endoscopy as a diagnostic tool or for placement of gastrostomy tubes is a standard ICU procedure...

In August 2001 the Mater Hospital in Belfast opened a new day procedures unit. The unit comprises an admissions area, two theatres, an endoscopy suite and a 23-bed ward, with one theatre almost solely dedicated to ophthalmic surgery. There are three consultant ophthalmologists who currently perform cataract, orbital, corneal, vitreoretinal and plastic surgery on a regular basis. In the four years that the unit has been running we have had a 57% increase in ophthalmic day case surgery.

The telementoring of surgical procedures is currently achieved via a wired infrastructure that usually requires sophisticated videoconference systems. This project represents the first step in assessing the potential for using handheld computers as a mobile alternative to current telementoring systems. Specifically, this project compares a handheld computer to a standard CRT monitor regarding their capability to accurately display video images from an endoscopic procedure. Video images from two previously recorded endoscopic procedures were transmitted from a standard VCR to: 1) a handheld computer (iPAQ 3670 running Pocket PC) via a wireless LAN and 2) a standard CRT monitor via a wired analog connection...

HYPOTHESES: Task performance improves with the use of a balanced degree of shadow and illumination compared with no or maximum shadow contrast; and overhead shadow-casting illumination is better than side illumination. DESIGN: The standard task entailed touching target points on an undulating surface by using a surgical hook. Each run consisted of 13 target points in a random sequence. Five settings were investigated: no shadow; 22%, 42%, and 65% shadow contrast created by overhead illumination; and 22% shadow contrast produced by side illumination...

Despite advancements in endoscopy and pharmacology in the treatment of peptic ulcer disease the overall mortality has remained constant at 10% for the past four decades. The aim of this study was to determine the age, gender, racial distribution, incidence and causes of endoscopically diagnosed cases of upper gastrointestinal (UGI) bleeding to summarise treatments undertaken and to report their outcome. A prospective study of UGI bleeding in 128 patients was performed in two surgical wards of Kuala Lumpur Hospital, involving both elective and emergency admissions...

Intravenous acid inhibition is used in the prevention of upper gastrointestinal bleeding in intensive care unit patients and in the treatment of peptic ulcer bleeding. The strongest risk factors for upper gastrointestinal bleeding are mechanical ventilation for more than 48 hours and coagulopathy. However, a subgroup of critically ill patients without these risk factors may still be at risk of upper gastrointestinal bleeding. Stress ulcer prophylaxis with sucralfate is not effective. Patients who receive intravenous ranitidine (50 mg every 8 hours) run a significantly lower risk of gastrointestinal bleeding...

BACKGROUND: Screening with a fecal occult blood test (FOBT) has been shown to reduce colorectal cancer mortality in controlled trials. Recently, Medicare approved payment for FOBT screening. We evaluated the pattern of diagnostic testing following the initial FOBT in elderly Medicare beneficiaries. Such follow-up testing would in the long run influence both the cost and the benefit of widespread use of FOBT. METHODS: Using Medicare's National Claims History System, we identified 24 246 Americans 65 years old or older who received FOBT at physician visits between January 1 and April 30, 1995...

The clinical need for sphincter of Oddi manometry (SOM) was investigated by retrospective analysis of 736 consecutive endoscopic retrograde cholangiopancreatography (ERCP) referrals (1985-89). During this period SOM was not performed in any unit in Greece including our own. Assuming a conservative or a more liberal policy in the utilization of SOM, a biliary and a pancreatic group of patients were established respectively, depending on the clinical presentation. ERCP was diagnostic in 168/194 (86.6%) of patients referred for post-cholecystectomy symptoms, but SOM was considered to be necessary to establish a diagnosis in the remaining 26 (13...

The introduction of powerful and inexpensive personal computers (PC) enabled us to develop a documentation system for upper gastrointestinal endoscopy. The system was programmed using the database management system dBASE III. It works on-line, and no computer knowledge or additional staff is needed to run the system. It is now routinely used in the endoscopic units of three different hospitals. Features of performance are a menu-driven data input, automatic report generation and record retrieval, listing according to different criteria as well as other dBASE III facilities...
