Abstract
Introduction & Objective: Transverse and midline abdominal incisions are both commonly used for elective major upper abdominal surgery. Both incisions have specific effects on abdominal wall function, leading to postoperative differences in clinical parameters such as pulmonary function, pain and wound healing. We conducted a prospective study to compare the effects of midline and transverse incision on pulmonary function. Materials & Methods: We studied 70 patients undergoing elective upper abdominal surgery in two groups: transverse group (35 patients) and midline group (35 patients). The parameters of forced vital capacity (FVC) forced. Expiratory volume in one second (FEV1) and the ratio of FEV1/FVC were measured in all patients before and after laparotomy by two spirometries. Finally the SPSS (version 13) was used for completing all the statistical analyses, and P< 0.05 was considered as significant. Results: The mean in all parameters decreased after laparatomy in both groups, but the decrease in midline incision was significantly higher than the case of transverse Incision (P<0.05). Conclusions: Transverse incisions in abdominal surgery are based on better anatomical and physiological principles. Thus, this incision is the preferred for upper abdominal surgery.
