Given curricular time constraints, the complex relationships of pelvic viscera can be difficult for students to master. We developed an interactive 3‐dimensional virtual pelvic model using high‐resolution 3‐Telsa magnetic resonance and 64‐slice computed tomographic datasets of a healthy male. The aim of this study was to determine if use of this curricular adjunct was associated with improved comprehension of pelvic anatomy as measured by a 33 item test. The software was distributed to 47 first year medical students during their 3‐day pelvic anatomy curriculum. Forty students (85%) completed the test. Students used the software for a median of 15 (interquartile range [IQR] 10 – 22) minutes; total minutes studying pelvic anatomy was 240 (IQR 125 – 525) minutes. Minutes of software use was strongly associated with the total study time (p<0.0001). On univariate analysis, pelvic anatomy test scores were associated with both minutes of software use (p=0.05) and total study time (p=0.04). On multivariate analysis both software use (p=0.12) and total study time (p=0.08) trended towards significant association with test scores. Most students used the software alongside books to aid in initial spatial orientation to the pelvis. Virtual anatomy software can be a valuable, effective adjunct to traditional anatomy education.

Short-term outcomes after elective minimally invasive colectomy for diverticulitis
Abstract Background The role of minimally invasive surgery in complicated diverticulitis is still being elucidated. The aim of this study was to compare short-term outcomes in patients undergoing minimally invasive surgery for complicated or uncomplicated diverticular disease. Methods All patients who had elective minimally invasive surgery for diverticulitis between 2003 and 2008 were identified from a prospectively maintained database. Complicated disease was defined as diverticulitis associated with abscess, fistula, stricture or bleeding. Univariable analysis was performed to compare safety and short-term outcomes in patients with complicated and uncomplicated diverticulitis. Results A total of 361 patients (136 with complicated and 225 with uncomplicated diverticulitis) were operated on with either a laparoscopic (36·0 per cent) or a hand-assisted laparoscopic (64·0 per cent) surgical technique. There were no significant differences between the groups with respect to age, sex, body mass index, laparoscopic approach, postoperative recovery protocol or previous open surgery. Conversion rates were similar for complicated and uncomplicated disease (14·0 versus 11·6 per cent respectively; P = 0·514). There was no difference between the groups with respect to return of bowel function (mean 3·1 versus 3·2 days respectively; P = 0·156), morbidity (27·9 versus 19·6 per cent; P = 0·070) or mean length of stay (5·4 versus 4·8 days; P = 0·186). There were no deaths within 30 days. Conclusion Elective minimally invasive colectomy is feasible for patients with uncomplicated and complicated diverticulitis, with equivalent outcomes.
