Many patients with endometriosis come to a consultation at Pacific Endometriosis and Pelvic Surgery with a history of one or more prior abdominal or pelvic surgeries. These may include Cesarean sections, prior laparoscopies for ovarian cysts or endometriosis, and even hysterectomies. It is important to recognize that each operation leaves behind changes in the pelvis that can influence future symptoms and surgeries.

A known risk of any prior surgery is the formation of adhesions. This concern is often raised as a reason not to pursue excision surgery—out of fear that surgery itself will create problematic scar tissue. While adhesions are a real and well-described part of the healing process, their likelihood and severity depend heavily on surgical technique. When an operation is performed meticulously, with careful tissue handling and attention to minimizing bleeding and inflammation, the risk of clinically significant adhesions is often far lower than many patients imagine.

One of the most challenging situations, however, occurs when advanced stage endometriosis was not fully excised at a prior surgery. In this scenario, the issue is not simply scar tissue from healing—it is the combination of ongoing active disease and scarring from the prior operation. Examples include endometriomas that were drained or only partially excised, or hysterectomies performed without addressing nearby deeply infiltrating endometriosis. Over time, this combination of persistent disease and reactive scarring can significantly distort pelvic anatomy. At a subsequent operation, it may take considerably longer to address both the scar tissue and the endometriosis. It can also be technically more difficult to distinguish dense, fibrotic endometriosis from surgical scar tissue, as the two can appear remarkably similar.

The takeaway is that the first endometriosis surgery is critical and carries long-term implications. When endometriosis is carefully evaluated and thoroughly excised by a surgeon experienced in complex pelvic disease, it can help preserve anatomy, limit progressive distortion, and reduce the likelihood of avoidable repeat procedures. Thoughtful planning from the start can make a meaningful difference in long-term outcomes—and in how patients feel moving forward.
