There is wide variation among laparoscopic colon resection techniques, including the approach for mobilization and the extent of intracorporal vessel ligation, bowel division or anastamosis. We compared the short-term outcomes of laparoscopic right hemicolectomy (LRHC) with intracorporeal (IA) versus extracorporeal (EA) anastamosis. We retrospectively reviewed all elective laparoscopic right hemicolectomies performed at St. Joseph's Hospital between January 2008 and September 2009 and compared the demographic, pathologic, operative and outcome data. Fifty LRHCs were completed during the study period: 21 IA and 29 EA. The groups were similar in age, sex, body mass index, American Society of Anesthesiologists score, previous laparotomy and preoperative invasive pathology. There was no difference between IA and EA in mean duration of surgery (170 v. 181 min, p = 0.78), estimated blood loss (14 v. 42 mL, p = 0.15), perioperative blood transfusions (5% v. 14%, p = 0.29), in-hospital morbidity (33% v. 41%, p = 0.56), out-of-hospital morbidity (19% v. 31% p = 0.34), emergency department visits (10% v. 17%, p = 0.16) or 30-day readmissions (5% v. 7%, p = 0.75). There was 1 anastamotic leak in each group and no perioperative deaths. Median length of stay was significantly shorter for IA (4 v. 5 d, p = 0.05). There were 6 extraction site hernias with EA and none with IA (p = 0.026). Laparoscopic right hemicolectomy with IA has the advantage of a less hernia-prone Pfannenstiel extraction site, faster recovery and shorter stay in hospital EA.

The Focused Assessment with Sonography for Trauma (FAST) examination has become a valuable tool in trauma resuscitation. Despite the widespread use of FAST training among traumatologists, no evidence-based guidelines exist to support optimal training requirements or to provide quantitative objective assessments of imaging capabilities. Both Task-Specific Checklist (TSC) and Global Rating Scale (GRS) have been validated as objective skill assessment tools; we developed both types of scoring checklist and assessed them for construct validity with the FAST examination. Two scoring checklists, collectively termed the Quality of Ultrasound Imaging and Competence (QUICk) Score, were developed and subjected to a modified Delphi consensus process. Two cohorts of 12 novice and 12 expert sonographers performed the FAST examination and were evaluated by two experts according to the QUICk model. Total scores as well as anatomic subsets were compared via comparison of means, and logistic regression modeling was used to determine sensitivity and specificity. Experts achieved significantly higher total scores than novices on both scoring systems (17.2 vs. 11.1 of 24, p < 0.01 TSC, 29.8 vs. 18.4 of 40, p < 0.01 GRS). Sensitivity (85.7% TSC, 92.9% GRS) and specificity (75.0% TSC, 91.7% GRS) as well as area under the receiver operating characteristic curve (89.9% TSC, 97.6% GRS) were consistent with a highly discriminant tool. The QUICk Score is the first validated objective tool for assessment of the quality of FAST examination imaging. Use of this tool may be instrumental in developing an evidence-based minimum-performance standard and for assessing quality-improvement modifications in FAST examination training.

Background: Gastrointestinal endoscopy is an integral tool in the evaluation and management of many gastrointestinal and hepatobiliary conditions. Although rare, media reports of infectious complications following gastrointestinal endoscopy persist in this new millennium. With only limited data available, society guidelines continue to suggest that endoscopes undergo a reprocessing cycle before the first patient of the day. This preliminary study aimed to assess the microbiological stability of gastrointestinal endoscopes after high-level disinfection. Methods: In this multiphase study, four endoscopic retrograde cholangiopancreatography (ERCP) scopes and three colonoscopes were evaluated. In phase 1, endoscopes were assayed after initial high-level disinfection and daily for a period of 2 weeks. In phase 2, this procedure was repeated to confirm phase 1 results. In phase 3, endoscopes were assayed after high-level disinfection and again following a 7-day storage period. Results: In phase 1, 6 of 70 (8.6 %) assays were positive. This involved 4 of 7 (57 %) endoscopes (2 colonoscopes and 2 ERCP scopes) and was limited to the first 5 days of the study. No cultures were positive in phase 2. In phase 3, one endoscope had a positive culture. Positive cultures grew only Staphylococcus epidermidis, a low-virulence skin organism. Discussion: With proper disinfection and storage, it appears that reprocessing of gastrointestinal endoscopes is unnecessary after periods of disuse of at least 7 days and possibly up to 2 weeks. Despite recent media reports of infectious complications, society guidelines that recommend more frequent reprocessing seem to lack scientific merit and need to be revisited.
