Introduction:

Laparoscopic assisted single port appendectomy offers an alternative approach to acute appendicitis. This study compares this technique versus open appendectomy and determine its therapeutic benefit.

Materials and methods:

retrospective cohort analytical observational study at the San Rafael Clinical University Hospital, Bogotá.

Results:

We included 106 patients older than 15 years with acute appendicitis who underwent appendectomy for single port assisted by laparoscopy versus appendectomy. The relationship between exposed and unexposed was 1:1. Sociodemographic, clinical and surgical variables were included (surgical time, frequency of infection of the operative site, hospital stay, pain, readmissions, and aesthetic result). Average age was 32 years, being the majority males. We observed less operative time in appendectomy for single port assisted by laparoscopy (34.1 min), postoperative pain measured according to analogous pain scale, was 2.2 in laparoscopy and 3.2 in open appendectomy (p: <0.05). Eight times more readmissions were observed in open appendectomy versus lap appendectomy, with satisfactory aesthetic results of 100% in single port. No significant differences were found in hospital stay and operative site infection. OR less than 1 was observed in variables such as pain, readmission and shorter surgical time indicating lower probability in single port.

Discussion:

The single port technique is a safe, reproducible technique, comparable in terms of days of hospital stay and operative site infection and even with better results in surgical time, pain scales and fewer re-admissions.
