"Postoperative fluid collections from lower abdominal or pelvic surgery and abscesses from the intraperitoneal spread of pelvic infections are more common in subcompartments of the right supramesocolic space than subcompartments of the left supramesocolic space. This is due to the communication between the pelvic peritoneal space and the right supramesocolic spaces via the right paracolic gutter. Conversely, the left paracolic gutter is shallower and the phrenicocolic ligament tends to limit communication between the left paracolic gutter to the left supramesocolic space. However, this ligament is variable in its presence, structure and location and therefore its ability to limit the spread of fluid and infection between the pelvic cavity and left supramesocolic space 1."
