Objective  To observe perioperative indexes and postoperative serum stress indexes of modified Stoppa surgery in treatment of pelvic and acetabular fracture.

  Methods  A total of 70 patients with pelvic and acetabular fractures were selected and randomly divided into modified group and conventional group, with 35 cases in each group. The conventional group was operated through the conventional ilioinguinal approach, and the modified group was given modified Stoppa approach surgery. The operative time, intraoperative hemorrhage, incision length, hospital stay and postoperative Visual Analogue of Pain (VAS) were compared between the two groups. The levels of serum cortisol (Cor), norepinephrine (NE) and epinephrine (E) before and after operation were compared between the two groups. The Majeed function score and postoperative complications of the two groups were compared.

  Results  The operation time, incision length and hospital stay of the modified group were significantly shorter, and intraoperative blood loss was significantly less than those of the conventional group (P < 0.05). The NE, E and Cor levels after operation in the modified group were significantly higher than before operation, but were lower than those in the conventional group (P < 0.05). The scores of sexual function and gait in the modified group were significantly higher than those in the conventional group after operation (P < 0.05). The total incidence of postoperative complications in the modified group was 17.14%, which was significantly lower than 40.00% in the conventional group (P < 0.05).

  Conclusion  Modified Stoppa surgery can shorten operative time, reduce bleeding loss and postoperative complications, accelerate postoperative recovery, and relieve stress response.
