RESUMO
The National quality Forum (NQF) published in 2002 a report defining 27 "serious reportable events" in healthcare, with one additional event added in 2006, completing a total of 28 "never events", which are events that should not occur or are highly preventable. A goal in this era of measuring quality through outcomes, is to not have any of these so-called "never events". A very successful way to improve outcomes in healthcare is achieved by simulation.

This paper includes commentaries on outcomes of esophageal surgery, including the mechanisms by which fundoduplication improves lower esophageal sphincter (LES) pressure; the efficacy of the Linx™ management system in improving LES function; the utility of radiologic characterization of antireflux valves following surgery; the correlation between endoscopic findings and reported symptoms following antireflux surgery; the links between laparoscopic sleeve gastrectomy and decreased LES pressure, endoscopic esophagitis, and gastroesophageal reflux disease (GERD); the less favorable outcomes following fundoduplication among obese patients; the application of bioprosthetic meshes to reinforce hiatal repair and decrease the incidence of paraesophageal hernia; the efficacy of endoluminal antireflux procedures, and the limited efficacy of revisional antireflux operations, underscoring the importance of good primary surgery and diligent work-up to prevent the necessity of revisional procedures.

BACKGROUND: We developed a novel curriculum teaching 20 open surgical skills in 5 general domains (instrument handling, knot tying, simple wound closure, advanced wound closure, and hemostasis). The curriculum includes online didactics, skills practice, and defined performance metrics, but is entirely self-guided with no expert oversight or teaching. METHODS: Subjects included first- and second-year medical students (n = 9). Subjects first viewed a demonstration video depicting proper technique. The pretest was video-recorded performance of each skill. Subjects then completed the self-guided skills curriculum at their own pace, returning for posttesting once they met defined self-assessment criteria. Performance was evaluated through both self-assessment and blinded video review by 2 expert reviewers using previously validated scales. RESULTS: After completion of the curriculum, performance improved significantly by both self-assessment (3,754 ± 1,742 to 6,496 ± 1,337; P < .01, Wilcoxon signed ranks) and expert assessment (10.1 ± 2.6 to 14.6 ± 2.7; P = .015). When analyzed by the 5 general domains, performance was significantly better for all domains by self-assessment (P < .05 for all domains) and in 4 domains by expert assessment (P < .04 for all domains other than instrument handling). CONCLUSION: Completion of a self-guided basic surgical skills curriculum allows novice learners to significantly improve performance in basic open surgical skills, without traditional expert teaching. This curriculum is useful for medical students and incoming junior residents.

BACKGROUND: Treatment for achalasia is aimed at the lower esophageal sphincter (LES), although little is known about the effect, if any, of these treatments on esophageal body function (peristalsis and clearance). We sought to measure the effect of various treatments using combined manometry (peristalsis) with Multichannel Intraluminal Impedance (MII) (esophageal clearance). METHODS: We enrolled 56 patients with Achalasia referred to the University of Washington Swallowing Center between January 2003 and January 2006. Each was grouped according to prior treatment: 38 were untreated (untreated achalasia), 10 had undergone botox injection or balloon dilation (endoscopic treatment), and 16 a laparoscopic Heller myotomy. The preoperative studies for 8 of the myotomy patients were included in the untreated achalasia group. Each patient completed a dysphagia severity questionnaire (scale 0-10). Peristalsis was analyzed by manometry and esophageal clearance of liquid and viscous material by MII. RESULTS: Mean dysphagia severity scores were significantly better in patients after Heller Myotomy than in either of the other groups (2.0 vs. 5.3 in the endoscopic group and 6.5 in untreated achalasia, p < 0.05). Peristaltic contractions were observed in 63% of patients in the Heller myotomy group, compared with 40% in the endoscopic group and 8% in untreated achalasia (p < 0.05 for both treatment groups vs. untreated achalasia). Liquid clearance rates were significantly better in both treatment groups: 28% in Heller myotomy and 16% in endoscopic treatment compared to only 5% in untreated achalasia (p < 0.05). Similarly, viscous clearance rates were 19% in Heller myotomy and 11% in endoscopic treatment, vs. 2% in untreated achalasia (p < 0.05). In the subset of patients who underwent manometry/MII both pre- and postoperatively, peristalsis was observed more frequently postoperatively than in preop studies (63% of patients exhibiting peristalsis vs. 12%), as was complete clearance of liquid (35% of swallows vs. 14%) and viscous boluses (22% of swallows vs. 14%). These differences were not significant, however. In the patients who had a myotomy the return of peristalsis correlates with effective esophageal clearance (liquid bolus: r = 0.46, p = 0.09 and viscous bolus: r = 0.63, p < 0.05). There is no correlation between peristalsis and bolus clearance in the endoscopic treatment group. CONCLUSIONS: With treatment Achalasia patients exhibit some restoration in peristalsis as well as improved bolus clearance. After Heller Myotomy, the return of peristalsis correlates with esophageal clearance, which may partly explain its superior relief of dysphagia.
