Which ligament limits the spread of ascitic fluid into the left paracolic gutter?

• A. Gastrohepatic ligament
• B. Phrenicocolic ligament
• C. Hepatorenal ligament
• D. Transverse mesocolon

Answer: (B)

Many peritoneal reflections create routes and barriers for intraperitoneal fluid. Fluid tends to move along the paracolic gutters, which run along the sides of the colon. The left paracolic gutter is bounded superiorly by the phrenicocolic ligament, a peritoneal fold that extends from the splenic flexure to the left hemidiaphragm. This ligament acts as a barrier, limiting ascitic fluid from spreading upward into the left subphrenic region and into the left paracolic gutter. Thus, fluid is less likely to track into that gutter because the phrenicocolic ligament blocks it. The other ligaments mentioned aren’t involved in this barrier: the gastrohepatic ligament is part of the lesser omentum between liver and stomach; the hepatorenal ligament connects the liver to the kidney; and the transverse mesocolon attaches the transverse colon to the posterior abdominal wall and doesn’t specifically regulate flow into the left paracolic gutter.
