Diathermy versus Scalpel incision in elective midline laparotomy: A prospective randomized controlled clinical study
Abstract
Methods: This was a prospective randomized clinical study which was conducted in the surgical wards of Bugando Medical Centre between January 2010 and December 2011. Patients were randomly assigned to two groups i.e. Group A (Scalpel group) and Group B (Diathermy group).
Results: A total of 214 patients were enrolled in the study. Of these, 108 patients were randomized to Group A (Scalpel group) and 106 patients to Group B (Diathermy group). The two groups did not differ significantly in relation to age and sex (p > 0.001). Laparotomy skin incisions using diathermy were significantly quicker than scalpel incisions (p = 0.001). There was significantly less blood loss in the diathermy group compared with the scalpel group (P =0.012). The mean visual analogue scale was significantly reduced more in the diathermy group than in Group Scalpel group patients on postoperative day 1 (p =0.001), day 2 (p =0.011) and 3 (p =0.021) respectively. The mean amount of intramuscular analgesic
requirement was significantly less in the Diathermy group than in the Scalpel group (p=0.021). Postoperative complication rates did not differ significantly between the Scalpel and Diathermy groups (p = 0.243). There was no significant difference between two groups with respect to the mean length of hospital stay (p = 0.834).
Conclusion: We conclude that diathermy incision in elective midline laparotomy has significant advantages compared with the scalpel because of reduced incision time, less blood loss, reduced early postoperative pain and analgesic requirements.
