The decision to use water-soluble enema or stenting as a bridge to definitive surgery depends on which factors?

• A. Location of obstruction and patient condition
• B. Time since obstruction
• C. Patient age
• D. Extent of metastasis

Answer: (A)

The idea behind bridging to definitive surgery is to relieve the obstruction safely before a planned operation, so where the blockage is and how well the patient can tolerate procedures largely decide which decompression method to use. The location of the obstruction matters because certain segments of the colon are easier to access and stent endoscopically; left-sided or distal lesions are generally more amenable to colonic stenting, while more proximal or technically challenging obstructions may not be suitable for a stent and might be managed with a decompression approach such as a water-soluble enema. The patient’s condition matters because endoscopic or radiologic decompression carries procedural risks and requires the patient to be reasonably stable, without signs of perforation or generalized peritonitis, and with enough physiological reserve to undergo a procedure. If someone is unstable or has concerning signs that mandate urgent surgery, bridging procedures may not be appropriate regardless of location. Age and extent of metastasis affect overall prognosis but do not directly determine the immediate choice of bridging technique. Time since obstruction can influence urgency, but the primary determinants are where the obstruction is and how well the patient can tolerate the decompression approach.
