Study population
In total 475 procedures were registered. Nine cases were removed because of diagnostic procedures and 47 cases were removed because no deep endometriosis was present in compartment A, B, C or F. This resulted in a total of 419 DE cases. Baseline characteristics are presented in Table 1. The mean age of women who underwent surgery was 35.3±6.5 years, with a median BMI of 24 (IQR 21-28) kg/m2. The majority of women had one or more previous abdominal surgeries; 13% reported more than 2 procedures. The primary indication for surgery were pain symptoms (82%).
