Comment on “Surgical treatment of ovarian endometriomas: state of the art?”

13 11 2012

To the Editor:

We read with interest the recent review conducted by Jadoul et al. (1) on the surgical treatment of ovarian endometriomas. The authors stress, as we do, that laparoscopic cystectomy for ovarian endometriomas may be difficult, and that a meticulous surgical technique should be used. The stripping technique, similar to that used for other benign cysts, cannot be used for this situation as it may induce severe bleeding and damage to the ovary (2, 3, 4). As we published before, the authors suggest that whenever the plane is adequately exposed, the surgeon may identify “arrows” on the surface of the cyst wall. These “arrows” help the surgeon to identify the correct cleavage plane. Indeed, a precise cut on the top of the arrow will present a safe and bloodless plane close to the cyst wall and away from the normal ovarian tissue, which should be preserved as much as possible.

However, we found that the “arrows” shown by the authors of this paper are not well representative of this very important laparoscopic sign. Looking at their pictures, readers may understand that the “arrows” are visible on the remaining ovarian stroma, whereas we emphasized several times that the “arrows” are visible on the surface of the cyst (4). Some examples of what we consider good surgical “arrows,” which should be followed to avoid unnecessary ovarian damage, are presented in Figure 1.

Finally, we would like to emphasize that this very accurate surgical sign is visible only when exposure and hemostasis are adequate.

Figure 1. In all examples C means cyst wall and O means ovarian tissue. The surgeon should cut the arrows visible on the cyst wall (green arrows), not those more rarely identified on the normal ovarian tissue (red arrows).
