Locate a gastrointestinal twist, assess viability, and distinguish sigmoid, cecal, midgut and gastric treatment routes while planning prevention of recurrence.
Same twist, different rescue. A stable sigmoid volvulus may be untwisted endoscopically. A cecal volvulus usually needs surgery. A newborn with midgut volvulus cannot wait for an adult colonic treatment pathway. First locate the twist, then assess whether blood flow or bowel integrity is threatened.
A twist can obstruct both contents and circulation
Volvulus occurs when part of the gastrointestinal tract twists around its supporting attachments. The twist can block the lumen and compromise the vessels traveling with it. Venous congestion and swelling can progress to impaired arterial perfusion, ischemia, and perforation. The clinical task is therefore not just to empty distended bowel. It is to identify the affected segment and protect viable tissue. [1][2]
Separate the emergency from the procedure
Increasing continuous pain, peritonitis, shock, fever, acidosis, or suspicious wall enhancement requires urgent assessment for ischemia or perforation. A patient does not need every finding before the situation becomes dangerous. CT can define the twist, obstruction, and complications when appropriate. A recognizable radiographic shape helps localize the problem but does not prove that the bowel is viable. [1][2]
Initial care addresses circulation, pain, vomiting, and the need for decompression while surgical expertise is engaged. The route of definitive treatment depends on the segment and its condition. Do not carry the sigmoid endoscopy rule into cecal or midgut volvulus. Even at one location, viable bowel and perforated bowel require different plans. [1][3]
The segment twists. Passage through the lumen becomes obstructed. [1]
Vascular drainage is compromised. Congestion and edema can make the trapped segment less safe. [2]
Perfusion may fail. Ischemia or perforation changes the urgency and the procedure. [1]
Two questions stay on the screen. Which segment is twisted? Is it still viable? [1]
