OBJECTIVE: To review reports on the transmission of infections by flexible gastrointestinal endoscopy and bronchoscopy in order to determine common infecting microorganisms, circumstances of transmission, and methods of risk reduction. DATA SOURCES: Relevant English-language articles were identified through prominent review articles and a MEDLINE search (1966 to July 1992); additional references were selected from the bibliographies of identified articles. STUDY SELECTION: All selected articles related to transmission of infection by gastrointestinal endoscopy or bronchoscopy; 265 articles were reviewed in detail. DATA SYNTHESIS: Two hundred and eighty-one infections were transmitted by gastrointestinal endoscopy, and 96 were transmitted by gastrointestinal endoscopy, spectrum of these infections ranged from asymptomatic colonization to death. Salmonella species and Pseudomonas aeruginosa were repeatedly identified as the causative agents of infections transmitted by gastrointestinal endoscopy, and Mycobacterium tuberculosis, atypical mycobacteria, and P. aeruginosa were the most common causes of infections transmitted by bronchoscopy. One case of hepatitis B virus transmission via gastrointestinal endoscopy was documented. Major reasons for transmission were improper cleaning and disinfection procedures; the contamination of endoscopes by automatic washers; and an inability to decontaminate endoscopes, despite the use of standard disinfection techniques, because of their complex channel and valve systems. CONCLUSIONS: The most common agents of infection transmitted by endoscopy are Salmonella, Pseudomonas, and Mycobacterium species. To prevent endoscopic transmission of infections, recommended disinfection guidelines must be followed, the effectiveness of automatic washers must be carefully monitored, and improvements in endoscope design are needed to facilitate effective cleaning and disinfection.

BACKGROUND: Although most diagnostic GI endoscopic procedures in Germany are performed on an outpatient basis, there is no large-scale prospective evaluation of complication rates. METHODS: Ninety-four gastroenterologists and internists from all regions of Germany recorded the number of EGD, colonoscopies, and polypectomies performed over a period of 1 year. All serious complications occurring in relation to the procedure, including the use of medication, were recorded in a structured protocol. RESULTS: A total of 110,469 EGDs, 82,416 colonoscopies, and 14,249 polypectomies were evaluated. The "reach-the-cecum-rate" was 97% (median). The overall complication rates for EGD, colonoscopy, and polypectomy were low compared with published data (0.009%, 0.02%, and 0.36%, respectively). The perforation rates were 0.0009%, 0.005%, and 0.06%, respectively, the rates of significant hemorrhage 0.002%, 0.001%, and 0.26%, respectively, and the mortality rates 0.0009%, 0.001%, and 0.007%, respectively. The rates of cardiorespiratory complications associated with EGD and colonoscopy were 0.005% and 0.01%, respectively. The overall complication rate for all procedures (diagnostic and therapeutic) was lower for gastroenterologists (1 per 5155 procedures) than internists (1 per 1539 procedures). Most of the adverse events associated with diagnostic endoscopy were attributable to use of medication. The severity score ranged from 2 to 5 for most of the adverse events occurring as a result of diagnostic procedures and 2 to 50 for polypectomy. The severity sum score per 10,000 procedures was 26 for EGD, 67 for colonoscopy, and 1185 for polypectomy. CONCLUSIONS: Outpatient endoscopy performed in practice settings by German gastroenterologists and internists is safe. The low complication rates may partly be explained by the high degree of experience resulting from the larger numbers of procedures performed relative to the numbers performed by gastroenterologists in hospitals and in other countries.

Percutaneous endoscopic gastrostomy has become the procedure of choice for the establishment of enteral feedings in most clinical settings. Minor modifications in the technique and tools of PEG may have had some effect on the type of complications seen with this procedure. The major and minor complications of PEG are reviewed with a focus on those manipulations that may assist in reducing the incidence of common complications of this procedure.

From September 1995 through May 1999, percutaneous endoscopic gastrostomy (PEG) was performed in 47 elderly patients, aged 65 to 93 (average 78.9). Several treatments were additionally performed to prevent serious complications in these cases, and their usefulness and problems were investigated. Gastropexy was performed to prevent peritonitis in cases of self-removal of tubes in the acute stage. Intraoperative fluoroscopy was used prevent perforation of the intestines. However, re-insertion of the endoscopic, which was necessary with the push method, was omitted to reduce the burden on the patients. In patients with tube troubles in the chronic stage such as the buried bumper syndrome or self-removal, the existing fistula was preserved and the gastrostomy was reconstructed using a narrow polyvinyl chloride tube and a flexible guide wire to prevent peritonitis by erroneous insertion of the tube. In terms of results, gastropexy was useful to prevent peritonitis in one patient with early self-removal of the tube. Data to evaluate the usefulness of fluoroscopy in preventing perforation of the intestine were insufficient, so more patients need to be studied in the future. Even when confirmation of the location of the internal bumper by endoscopy was omitted, there was no case of poor traction of the bumper, so this procedure seems unnecessary. Review of tube troubles, in the chronic stage revealed no case of peritonitis caused by erroneous insertion of tubes or erroneous injection of nutrients with our reconstruction methods, and complete reconstruction of the gastrostomy with preservation of the existing fistula appeared to be possible. However, those additional treatments require extension of the operation time and rise in cost with increased use of medical instruments, so the indications should be carefully considered.

Recent economic changes in health care delivery have led to more frequent feeding by tube enterostomy. Over the last two decades percutaneous endoscopic gastrostomy (PEG) has been established as the standard method for long-term enteral access for nutrition, though operative gastrostomy remains indicated in a few conditions. Additionally, the combined gastrojejunostomy tube is indicated in selected patients in need of concomitant access to the jejunum and gastric decompression. This report reviews data regarding the safety and efficacy of the PEG tube and the indications for operative gastrostomy. Complications of feeding tubes and strategies to avoid or remedy them are also discussed. More recent techniques, including laparoscopic gastrostomy and jejunal access via the stomach, are reviewed as are some ethical concerns regarding the appropriateness of feeding enterostomies in certain patients.
