Obstructive ileus caused by metal staples 6 years after the initial surgery: A case report.

Rationale: Complete small bowel obstruction (SBO) is a common surgical emergency often resulting from adhesive bands installed after a surgical procedure. However, SBO caused by surgical staples used in a previous operation is unusual. Herein, we report a rare case of adhesive ileus induced by surgical staples.
Patient's Concerns: A 58-year-old woman visited our Emergency Department with right lower quadrant (RLQ) pain and vomiting. The patient had undergone laparoscopic total hysterectomy with the Endo GIA stapler for uterine myoma 6 years prior.
Diagnoses: Computed tomography (CT) revealed a closed-loop obstruction with volvulus involving the distal ileum.
Interventions: After suspected failure of conservative therapy with fluid resuscitation and Levin tube decompression, emergency laparoscopic surgery was performed. A fibrous band around the surgical staples considered to have been used in a previous operation was observed which extended to the greater omentum, through which a segment of the bowel formed a closed-loop obstruction around the right ovary.
Outcomes: The patient's symptoms resolved and a follow-up on post-operative day 14 showed no symptoms.
Lessons: Surgeons using surgical staples should be aware that adhesion may occur when the staples are exposed to the abdominal cavity, which can lead to the risk of SBO several years after surgery. Thus, staples should not be exposed to the abdominal cavity, or anti-adherent substances should be used to minimize the possibility of such complications.
