Immediate cystic duct occlusion using an endoluminal absorbable polyglycolic acid screw.
Endoscopic in situ occlusion of the cystic duct and ablation of the gallbladder could constitute a useful alternative to cholecystectomy in certain patients. The purpose of this study was to examine the feasibility of endoluminal occlusion of the cystic duct using a biodegradable polyglycolic acid screw and simultaneous gallbladder mucosal ablation with a Sotradecol-ethanol mixture. Eight pigs had operative cholecystotomy. A polyglycolic acid screw was twisted into the cystic duct after the proximal cystic duct mucosa was thermally ablated using electrocautery. Cholecystography confirmed occlusion of the cystic duct. Synchronous ablation of the gallbladder mucosa was then done by instilling absolute alcohol and 2% Sotradecol. The gallbladder was drained. Animals were sacrificed on days 14, 28, and 42. All animals survived operation and showed no untoward effects. Postmortem gross inspection showed gallbladders were shrunken and surrounded with adhesions from adjacent tissue. Cholangiography and cholecystography confirmed occlusion of the cystic duct in 6 of 8 pigs (75%). Histopathologic examination showed extensive areas of mucosal necrosis mixed with small areas of epithelial regeneration. Immediate occlusion of the cystic duct is possible using an endoluminal polyglycolic acid screw.

Laparoscopy-guided intracorporeal ultrasound accurately delineates hepatobiliary anatomy.
UNLABELLED: The purpose of this study was to develop a technique and assess the ability of a laparoscopic ultrasound probe to delineate biliary antomy and to determine the presence or absence of duct stones. METHODS: Five pigs had ultrasonography of biliary structures and liver at laparoscopy followed by cholangiograms and anatomical dissection. Five patients had ultrasonography of the biliary tract at laparoscopic cholecystectomy. RESULTS: All animals had adequate visualization of important hepatobiliary structure, and an optimal method of accessing these structures at laparoscopy was established. Patients had ultrasonography which used methods developed in the animal trial. All had adequate visualization of the entire common bile duct confirmed by cholangiography. Limitations in demonstrating the relationship of the cystic duct to the common duct were technical and can be corrected. CONCLUSION: Laparoscopic ultrasonography has significant potential for delineation of biliary anatomy and determination of presence or absence of duct calculi. Clinical implementation could minimize the risk of iatrogenic duct injury and the need for operative cholangiography.

Faculty perceptions of teaching on television: one school's experience.
Videoteleconferencing (or teaching on television) represents a means of growing importance for distant learners to gain greater access to nursing education. Research has identified a number of key issues for nurse educators to consider related to videoteleconferencing: teaching/evaluation strategies, faculty workload, rewards and incentives, and support structures. The authors conducted an evaluation survey using a case study approach aimed at describing the perceptions of a convenience sample of faculty members (n = 17) regarding their recent television experiences. The survey, conducted by means of a mailed questionnaire, examined perceptions centering on sources of support, reception site logistics, rewards teaching strategies, and future directions. Key findings included: overall, respondents perceived television teaching positively; reception site, administrative support, and peer support were important to faculty; additional preparation time was required for television teaching; teaching on television required changes in style and pedagogical strategies; and student-teacher interactions were affected by the medium. Findings have implications for the implementation of videoteleconferencing operations, recruitment of faculty for television teaching, and evaluation of videoteleconferencing operations.

The M.D.R. index of function in rheumatoid arthritis.
The M.D.R. index is a new instrument which has been designed to give a measurement of physical function in inflammatory joint disease. It is very easy to apply and is not time-consuming. In preliminary assessment, the index has proven to be highly reliable. It has also been sufficiently sensitive to detect short-term changes in functional capacity which were unrelated to changes in the severity of joint inflammation. The application of the index is inexpensive and does not require extensive training of personnel for its accurate use. It is expected that the M.D.R. index will prove to be suitable for widespread use as a clinical assessment of physical function.
