[Laparoscopic appendectomy as training procedure for all stages of appendicitis]

Current analysis of endoloops in appendiceal stump closure. Surg Endosc. 2011;25:124-129. [PMID: 20552371 DOI: 10.1007/s00464-010-1144-5]

BACKGROUND

An inadequate closure of the appendix stump leads to intra-abdominal surgical site infection. The effectiveness of various appendiceal stump closure methods, for instance, staplers or endoloops, was evaluated. Many analyses show that the use of a stapler for transection and closure of the appendiceal stump lowers the risk of this infection but a statistically significant risk of postoperative intra-abdominal abscess or wound infection was not considered in any randomized study. The aim of this study was to evaluate the complications after using endoloops in a high-volume center.

METHODS

The data of 1,790 patients who underwent laparoscopic appendectomy between January 1998 and December 2006 and a single center was prospectively acquired. The standard procedure used was an appendiceal stump closure using endoloops and a selective use of staplers. The outcome criteria for inclusion in the study were intra-abdominal abscess formations, other specific intraoperative and postoperative complications, and the different costs of the operation.

RESULTS

Laparoscopic appendectomy was performed in 1,790 (80.8%) patients and open appendectomy in 425 (19.2%) patients. Conversion to open surgery occurred in 74 (4.13%) patients. Laparoscopic appendectomy with stump closure using endoloops was performed in 1,670 (97.3%) patients and stump closure using a stapler in 46 (2.7%) patients. Among 851 patients with acute appendicitis, 284 patients with perforated appendicitis, and 535 patients with other or no pathology, the rate of intra-abdominal abscess after using an endoloop or a stapler was not significantly different (1.5 vs. 0%, p = 0.587; 3.5 vs. 4.2%, p = 0.870; 0.7% vs. 0, p = 0.881, respectively). There were no significant differences between the endoloop group and the stapler group with respect to the other specific intraoperative and postoperative complications.

CONCLUSION

This study shows the safety of the endoloop for clinical daily routine. A selective procedure for stump closure has been established. Appendiceal stump closure using an endoloop is an easy, safe, and cost-effective procedure.

Laparoscopic appendectomy in a district hospital: does the technique influence the outcome?

BACKGROUND

Laparoscopic appendicectomy (LA) has proved to be a safe, effective procedure for appendicitis. However, its application in the current surgical practice is still far less than the laparoscopic cholecystectomy. Therefore, its role as a gold standard operation for acute appendicitis (AA) is less well established.

METHODS

Between September 1999 and January 2007, a series of 200 patients (112 female, 88 male) with AA underwent LA in our surgical unit. A single consultant surgeon performed all the cases. Outcomes, including the length of stay, operative time, and complications, were evaluated. Follow-up assessment of patients was performed by outpatient appointment.

RESULTS

The indications for LA were clinical diagnosis of AA for 177 patients (85%) and interval appendicectomy for 23 patients (15%). The mean age of these patients was 18.8 years (range, 8-83). Operative diagnosis of inflamed appendix, including perforated appendicitis in 9 patients (7.5%), was made in 139 patients (69.5%), and the appendix was macroscopically normal in 40 patients (20%). Different pathologies were found in 21 patients (11.5%). Of the 40 (20%) macroscopically normal appendices, 10 (5%) appendices were reported as inflamed by histopathology examination. The operative time ranged from 13 to 62 minutes, with a mean of 18 minutes. Minor morbidity was reported in 11 patients (5.5%)

CONCLUSION

In experienced hands using a meticulous technique, LA provides diagnostic and therapeutic options, decreased operative time, rapid recovery, short hospital stay, fewer postoperative complications, and no intra-abdominal abscesses. Appendicectomy has cured right iliac fossa pain in almost all the patients.
