Study Objective:
To determine the frequency of postoperative adhesions to the anterior abdominal wall peritoneum that could affect safe placement of the initial laparoscopic umbilical cannula at subsequent procedures.
Design:
Prospective cohort study.
Setting:
Reproductive endocrinology and infertility service of a tertiary care referral hospital.
Patients:
Two hundred fifteen women, 124 with prior abdominal surgery and 91 with no prior surgery.
Interventions:
Surgical histories were reviewed, abdominal skin scars noted, and extent of anterior abdominal wall adhesions prospectively recorded. Statistical analysis was performed with the chi2 test.
Measurements And Main Results:
No anterior abdominal wall adhesions were present in 91 patients with no previous surgery or 45 patients with previous laparoscopy (12 had more than 1 laparoscopy; p <0.001 vs laparotomy). Seventeen (59%) of 29 patients with a midline vertical incision had anterior wall adhesions (p <0.05 vs suprapubic transverse incision). Eleven (28%) of 39 with a suprapubic transverse incision had anterior wall adhesions (p <0.001 vs no surgery or laparoscopy). Ninety-six percent of adhesions involved omentum and 29% included bowel.
Conclusion:
Prior laparotomy, whether through a midline vertical or suprapubic transverse incision, significantly increased the frequency of anterior abdominal wall adhesions, and these adhesions may complicate the placement of the laparoscopic cannula through the umbilicus.
