Background |
Postoperative radiographs demonstrating pneumoperitoneum are a vexing problem for surgeons. This dilemma stems from uncertainty regarding the length of time for resolution of gas introduced operatively via either an open or a laparoscopic approach. We attempted to quantify the duration of pneumoperitoneum after both laparoscopic and open surgery in an animal model.
Methods |
A prospective study using 2 groups of 10 pigs (Sus scrofa) was performed. The animals were assigned to undergo either an exploratory laparoscopy or an open abdominal exploration. Postoperatively, sequential computed tomography (CT) scans were performed to assess for the presence of pneumoperitoneum.
Results |
Pneumoperitoneum resolution occurred sooner than average on CT scan in the laparoscopic group when compared to open group (1.79 days vs 4.73 days respectively; P value of .02).
Conclusions |
Postoperative pneumoperitoneum resolves more quickly after laparoscopy when compared to open surgery in the porcine model. This information may aid in evaluating postoperative CT scans demonstrating pneumoperitoneum.
