Appendico-ileal knot: A rare form of small bowel obstruction: A case report.

INTRODUCTION AND IMPORTANCE

Small bowel obstruction (SBO) is a common surgical emergency with various causes. However, SBO resulting from appendicitis is uncommon and often overlooked. Appendico-ileal knotting, a rare and dangerous form of SBO, occurs when the appendix becomes twisted around the small intestine, leading to strangulation. Despite being reported since 1901, there have been very few documented cases of this condition. Diagnosing appendico-ileal knotting preoperatively is challenging, and even imaging techniques like computed tomography scans may not provide definitive diagnostic findings. Our current case report is a valuable addition to the limited literature and enhances understanding of this infrequent cause of SBO from a resource limited setting.

CASE PRESENTATION

We present the case of a 28-year-old female who presented with symptoms of dynamic SBO, including abdominal pain, vomiting, and constipation. Preoperative evaluation couldn't determine the exact cause.

CLINICAL DISCUSSION

Diagnosis of a strangulated ileum was discovered, with the appendix identified as the source intraoperatively, leading to an open retrograde appendectomy. Postoperatively, the patient received IV ceftriaxone (1 g daily), metronidazole (500 mg tds), paracetamol (1 g tds), and IV crystalloids. Oral intake resumed gradually, and discharge occurred on day 4. Follow-up on 10th day was uneventful.

CONCLUSION

Appendico ileal knotting is a rare cause of mechanical SBO. Knowledge of its pathophysiology, diagnosis, and management is very crucial to reduce its associated morbidity and mortality.
