"Clinical presentation "
"Closed-loop obstructions may also present as non-obstructive or partially obstructive conditions, in which venous congestion occurs subtly without significant luminal obstruction. This scenario can arise when the defect trapping the bowel is larger or less constrictive, such as in internal hernias post-gastric bypass 12. In these cases, bowel loops appear congested with vessels orientated toward the transition point, but without marked dilation. Patients may experience fewer acute symptoms and more intermittent discomfort."
"Strangulation refers to impaired blood flow (decreased perfusion) to the small bowel caused by obstruction, which can lead to bowel ischaemia. Closed-loop obstructions are at particular risk for ischaemia and infarction. This is mainly seen when the diagnosis is delayed (10-35% of small bowel obstructions) and associated with high mortality 6,15. Features are non-specific and include 13,14,15:"

"Clinical presentation "
"Complications"
"Closed loop obstructions are a specific type of bowel obstruction in which two points along the course of the bowel are obstructed; classically, but not always, the transition points are adjacent at a single location 7,15."
