Surgery · Appendix, Small Intestine and Intestinal Obstruction

A 70-year-old man presents with acute large bowel obstruction. CT abdomen shows a sigmoid colon carcinoma causing 95% luminal narrowing, no peritonitis, no perforation. The preferred treatment approach in a non-specialized center is:

  • A Emergency Hartmann's procedure
  • B Self-expanding metallic stent (SEMS) as bridge to surgery
  • C Primary resection and anastomosis with on-table colonic lavage
  • D Defunctioning loop colostomy followed by elective resection
Correct answer: B. Self-expanding metallic stent (SEMS) as bridge to surgery

Explanation

Self-expanding metallic stent (SEMS) as a bridge to elective surgery (BTS) is the recommended strategy for left-sided colonic obstruction without perforation or peritonitis in centers with adequate endoscopic expertise, as it decompresses the colon, allows staging, patient optimization, and enables a one-stage elective resection with primary anastomosis rather than a Hartmann's procedure. CREST trial and ESCO trial data favor SEMS-BTS in suitable candidates. Emergency Hartmann's procedure carries higher morbidity; primary anastomosis without stenting carries anastomotic leak risk in unprepared bowel.
