 Adhesions from prior abdominal or pelvic surgery may obscure visibility and access at subsequent abdominal or pelvic surgery.In a very large study (29,790 participants) published in British medical journal "The Lancet", 35% of patients who underwent open abdominal or pelvic surgery were readmitted to the hospital an average of two times after their surgery, due to adhesion-related or adhesion-suspected complications.Over 22% of all readmissions occurred in the first year after the initial surgery.
