Comparative Study of Pulse Wave Analysis and Other Hemodynamic Parameters in Medical Students: Initial Data

Background: Controversial evidence exists regarding the laparoscopic approach in patients with acute appendicitis complicated with peritonitis due to a higher rate of surgical complications. The aim of this study was to compare post-operatory outcomes in patients with acute appendicitis complicated exclusively with peritonitis approached by laparoscopy versus open surgery. Methods: Single center retrospective analysis of clinical records of patients with appendicitis complicated with peritonitis operated from January 2003 until October 2013. Demographic data, intra-operative variables, length of stay, surgical complications, mortality, readmissions and reoperations were retrieved. Results: 227 patients were identified, 43% males, mean age 39 ± 17 years (range: 12–85 years). Ninety-seven patients (43%) underwent laparoscopic appendectomy, 13 of them were converted to open surgery (13%). Ninety-four patients presented with diffuse peritonitis (41.4%). Laparoscopic appendectomy showed longer operative time but shorter hospital stay (p < 0.05). There were no differences in post-operatory complications (intra-abdominal abscess, surgical site infection and prolonged ileus). Laparoscopic appendectomy was associated with lower odds for developing any surgical complication in the multivariate analysis (OR 0.301, p = 0.036). Conclusion: Both approaches showed no differences in complications in the management of appendicitis complicated exclusively with peritonitis. In our experience, laparoscopic appendectomy is a safe approach in cases of appendicitis complicated exclusively with peritonitis.
