ABSTRACT
BACKGROUND AND OBJECTIVES: Use of ultrasound-guided regional anesthesia (UGRA) requires considerable training. An embedded electronic tutorial as an element of an ultrasound machine may help to identify sonoanatomy for novices. Therefore, we investigated whether an electronic tutorial could improve accuracy or speed of performance in identifying anatomical structures. METHODS: Thirty-five novices in UGRA participated in a workshop on brachial plexus sonoanatomy. Following a lecture and training in handling of ultrasound machines and hand-eye coordination, participants were randomized in either group S, using a standard ultrasound machine, or group T, using the same type of machine with an onboard electronic tutorial. Each participant had to identify 27 anatomical structures from the brachial plexus of a volunteer. A correctly identified structure scored 1 point. An experienced observer noted scores and time required. Scores ± SD (in %) and times ± SD (in seconds) were compared between groups by analyses of independent-samples t test and analysis of variance. Influence of anesthesia experience was determined by multivariate analyses. RESULTS: Group T scored significantly higher (16.8 ± 3.6 [62%] vs. 13.4 ± 4.4 [50%], P = 0.018), whereas time required was longer (1053 ± 244 vs. 740 ± 244 seconds, P = 0.001). Multivariate analysis revealed that experience had no influence on scores or time required. Examination of structures took more time in the beginning than at the end in group T. CONCLUSIONS: An electronic tutorial can help novices in UGRA identify anatomical structures. A significant increase in correct identifications was gained at the expense of significantly longer time required for this process. Increased time required may partly be related to unfamiliarity with the tutorial.

BACKGROUND: Medical treatment of obesity often fails, and surgical treatment, although successful, is aggressive. OBJECTIVE: To evaluate the short-term safety and efficacy of an endoscopic restrictive implant procedure in the treatment of obesity. DESIGN: Prospective, observational study. SETTING: Tertiary-care referral hospital in The Netherlands. PATIENTS: This study involved 13 patients with body mass indexes of between 40 and 50 kg/m(2) or between 35 and 40 kg/m(2) with obesity-related comorbidities. INTERVENTION: A new transoral endoscopic restrictive implant procedure in the treatment of obesity. MAIN OUTCOME MEASUREMENTS: Safety of the procedure, percentage of excess weight loss, change in body mass index. RESULTS: In 1 patient, the procedure was abandoned after a gastric perforation related to stapler malfunctioning. In 2 patients, pneumoperitoneum was detected. This was desufflated with a percutaneous hollow needle in one patient and treated conservatively in the other. After these complications, technical adjustments were made in the procedure, and no subsequent procedural complications were seen. At 3 months postprocedure, patients obtained a median excess weight loss of 28%. Median body mass index decreased from 42.1 to 37.9 kg/m(2). LIMITATIONS: Small number of patients. CONCLUSION: Preliminary results of this transoral endoscopic restrictive implant system for the treatment of obesity showed successful placement in 12 of 13 patients. Procedural complications occurred in 3 patients. Weight loss was comparable to that of laparoscopic gastric band placement. Further long-term studies are under way.

BACKGROUND: The aim of this prospective double-cohort pilot study is to evaluate the feasibility and desirability of laparoscopic Nissen fundoplication (LNF) performed in day-care when compared with laparoscopic cholecystectomy (LC) in day-care. METHODS: Patients who underwent a LNF in day-care were prospectively evaluated. LNF patients were treated according to LC in day-care protocol. Outcome parameters were EQ-5D, visual analogue scale (VAS), and patient satisfaction. RESULTS: From October 2005 to March 2008, 22 patients underwent LNF and 48 patients LC in day-care. After LNF, 21 out of 22 (95%) patients were discharged the same day. Seven (32%) patients were seen postoperatively in the Emergency Department with dysphagia or pain and two (9%) patients were readmitted. After LC, 45 out of 48 (94%) patients were discharged the same day. Six (12.5%) patients were seen postoperatively in the Emergency Department because of wound infection or pain and three (6%) were readmitted. EQ-5D and VAS scores were significantly worse after LNF in day-care (repeated measurements, p < 0.0001 and p < 0.0001). In a telephone survey 66.7% preferred a short hospital stay over day-care surgery after LNF compared with 30.9% after LC (p = 0.011). CONCLUSIONS: LNF in day-care is feasible and safe, but postoperative pain scores are high and most prefer short hospital stay.
