With the advances in laparoscopic instruments and surgical techniques, the use of laparoscopic appendectomy (LA) has been increasing rapidly in recent years. In this retrospective analysis, we aimed to determine the competitive edge of LA versus open appendectomy (OA) in different settings of disease complexity, gender, and age difference.A retrospective analysis of the patients diagnosed with acute appendicitis at Changhua and Chang-Bing Show-Chwan Memorial Hospitals from January 1, 2004 to December 31, 2009 was conducted. Trend and indication of OA and LA were recorded, combined with a comparison of medical costs, complication rates, wound infection rates, and hospital stays in different settings of disease complexity, gender, and age group.A total of 1366 appendicitis patients were enrolled, and the rate of LA use increased rapidly, from 8.1% in 2004 to 90.3% in 2009. The increased use of LA was seen in both the uncomplicated and complicated appendicitis patients and in both gender and age groups (pediatric, adult, and elderly). Compared with OA, LA was associated with a lower complication rate (9.5% versus 5.8%; P = .013), a lower wound infection rate (8.6% versus 4.2%; P = .001), and a shorter hospital stay (4.60 ± 3.64 versus 4.06 ± 1.84 days; P = .001), but a higher mean cost (32,670 ± 28,568 versus 37,567 ± 12,064 New Taiwan dollars). In the subgroup analysis, the patients with complicated appendicitis, female patients, and pediatric and elderly patients benefited from a reduced hospital stay. LA is about 15% more expensive than OA.LA is as safe and effective as OA in many settings of appendicitis and may be selectively advantageous in patients with complicated appendicitis and in elderly subgroups.

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). 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. 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

Background Mucoceles resulting from cystadenomas of the appendix are uncommon. Although rare, rupture of the mucoceles can occur with or without causing any abdominal complaint. There are several reports associating colonic malignancy with cystadenomas of the appendix. Herein, we report an unusual and interesting case of right inguinal hernia associated with left colon cancer. Case presentation A case of ruptured mucocele resulting from cystadenoma of the appendix was presented as right inguinal hernia in a 70-year-old male. The patient underwent colonoscopy, x-ray, ultrasound and computed tomography. Localized pseudomyxoma peritonei associated with adenocarcinoma of the descending colon was diagnosed. The patient underwent segmental resection of the colon, appendectomy, debridement of pseudomyxoma and closure of the internal ring of right inguinal canal. He is free of symptoms in one year follow-up. Conclusion Synchronous colon cancer may occur in patients with appendiceal mucoceles. In such patients, the colon should be investigated and colonoscopy can be performed meticulously in cases of ruptured mucoceles and localized pseudomyxoma peritonei. Surgical intervention is the current choice of management.
