Background: Acute appendicitis is the most common acute abdomen in general surgery. Show-Chwan Memorial Hospital began an AITS/IRCAD laparoscopic training program in late May 2008. In this retrospective analysis, we surveyed the impact of the AITS training program on surgeons’ preference for open appendectomy (OA) versus laparoscopic appendectomy (LA). Methods: From January 1, 2004 to July 31, 2009, patients diagnosed with acute appendicitis in Changhua Show-Chwan Memorial Hospital and Chang-Bing Show-Chwan Memorial Hospital were retrospectively analyzed. Demographic data, laboratory examinations, surgical methods, hospital stay, and complication rate data were collected and analyzed. The LA rate and effect of surgeons’ preference before and after AITS were compared. Results: In all, 1,267 patients (58.2% male and 41.8% female; mean age, 36.6 years) were diagnosed with acute appendicitis during this period. Among them, 78.9% of patients had uncomplicated and 21.1% complicated appendicitis; 784 patients (61.9%) underwent OA, and 465 (36.7%) received LA. In 2004, only 8.1% of patients underwent LA, but the number increased rapidly to 90.4% in 2009 ( P < 0.001). The average LA rate before AITS was 21%; however, after AITS, the LA rate increased to 84.6% ( P < 0.001). The LA rate increased for all surgeons completing the training course, ranging from 16 to 83%. The overall appendectomy complication rate was 8.4%, with no significant difference between OA (9.7%) and LA (6.5%; P = 0.174). Hospital stay was shorter in the LA group (4.05 ± 1.9 days) compared with the OA group (4.55 ± 3.6; P = 0.006). Conclusions: Attending the laparoscopic training course significantly increased surgeons’ preference for LA. [ABSTRACT FROM AUTHOR]

Laparoscopic adrenalectomy offers distinct benefits to patients and has now become the gold standard for the removal of adrenal lesions. Nonetheless, the procedure poses a challenge for surgeons in regards to the maneuverability of instruments, the two-dimensional operating field and the counterintuitive movements. This study reports our experience using the Zeus robotic surgical system in laparoscopic adrenalectomy compared with traditional laparoscopic adrenalectomy. From January 2003 to February 2005, a total of 12 patients were prospectively enrolled to receive robot-assisted laparoscopic adrenalectomy (RALA) or traditional laparoscopic adrenalectomy (TLA). The time necessary for robotic setup and operation was recorded, as well as complications, technical problems, postoperative hospital stay, morbidity, and mortality. Five RALA procedures and seven TLA were successfully completed. There was no significant difference between the groups in terms of age, body mass index, and tumor size. Resection times were longer in the RALA group (168.0 ± 30.7 min vs. 131.4 ± 29.0 min, p = 0.05). There were no perioperative complications. There was neither postoperative mortality nor morbidity at the time of discharge and during one year follow-up. RALA is as safe and technically feasible as TLA, It provides a real benefit for the surgeon with the three dimensional view, a comfortable sitting position, the elimination of the surgeon’s tremor, and increased degrees of freedom of the operative instruments compared with TLA. However, patient outcomes and operative costs should be evaluated further. [ABSTRACT FROM AUTHOR]
