Summary
Postoperative pneumoperitoneum (PP) after abdominal surgery can be difficult to interpret. This review examines factors influencing PP prevalence and duration, aiding in differentiating residual air from surgical complications.
Area of Science:
- Abdominal Surgery
- Radiology
- Gastroenterology
Background:
- Free intraperitoneal air post-abdominal surgery presents a diagnostic challenge.
- Distinguishing residual postoperative pneumoperitoneum (PP) from complications like anastomotic leaks or perforations is crucial.
Purpose of the Study:
- To review factors influencing the prevalence of postoperative pneumoperitoneum (PP).
- To discuss the range of duration for residual PP.
- To aid in the diagnostic dilemma of free air after abdominal surgery.
Main Methods:
- Review of existing literature on plain film radiography and CT findings.
- Analysis of factors affecting PP prevalence and duration.
Main Results:
- Residual PP is typically benign and self-resolving.
- Free air indicating a leak or perforation signifies a surgical emergency.
Conclusions:
- Understanding PP prevalence and duration is key for accurate diagnosis.
- Radiological assessment aids in differentiating benign PP from critical intra-abdominal events.
