    Roux-en-Y gastric bypass (RYGB) is a leading surgical treatment for severe obesity, combining restrictive and malabsorptive mechanisms.

  • 2

    Roux-en-O complications arise from misidentifying bowel loops, leading to anastomosis errors that create functional obstructions.

  • 3

    The incidence of Roux-en-O is rare, with one study reporting 1.67% in a low-volume center, often linked to inexperienced surgical practices.

  • 4

    Patients with Roux-en-O present symptoms similar to small bowel obstruction, including nausea, abdominal pain, and bilious vomiting.

  • 5

    Radiologic diagnosis of Roux-en-O is challenging, often requiring surgical exploration for definitive confirmation of the misconstructed anatomy.
