Abstract

OBJECTIVE:

Several radiological studies have suggested that the base of the Appendix often does not correspond with Mc Burney's point. The aim of our study is to assess the value of using CT localization of the appendicocaecal junction to guide placement of the appendicectomy incision.

DESIGN & METHOD:

32 consecutive patients, booked for open appendicectomy were prospectively included in this study. Coronal and axial CT scans with IV contrast were studied to assess site of the appendicocaecal junction. This information was used to guide placement of the incision.

RESULTS:

28 out of 32 patients studied, the appendicocaecal junctions were accurately identified. It was noted that the final incision sites were cephalad to Mc Burney's point in 8, at the point in 3 and caudal in 17. In 1 patient, it was necessary to extend the incision medially by 2cm to retrieve the distal Appendix which had been detached through the site of rupture.

CONCLUSION:

Mc Burney's point often does not correspond to the base of the appendix. We propose that using CT imaging to guide the appendicectomy incision is safe, facilitates locating the Appendix at surgery, minimizes incision size and decreases the need to extend it.
