  1. (*) Group A: 26 patients, 6 lost to follow-up: 20 evaluable.
  2. (**) Group B: 75 patients, 17 lost to follow-up: 58 evaluable.
  3. (***) 1 intervention = initial laparotomy only.
  4. 2 interventions = first laparotomy + 1 laparostomy revision.
  5. 3 interventions = first laparotomy + 2 laparostomy revisions.
  6. 4 interventions = first laparotomy + 3 laparostomy revisions.
  7. > 4 interventions = first laparotomy + > 3 laparostomy revisions.
