Gangrenous Appendico-ileal knotting causing strangulated small-bowel obstruction and shock in a patient with a virgin abdomen: a case report
This case report describes a rare instance of gangrenous appendico-ileal knotting causing strangulated small-bowel obstruction and shock in a 52-year-old man with no prior abdominal surgery, highlighting the critical need for urgent operative intervention despite the difficulty of preoperative diagnosis.

Inside the human abdomen, a complex network of tubes carries food and waste, held in place by a flexible membrane that allows them to move freely. Occasionally, this mobility leads to a dangerous twist where one part of the intestine loops around another, or where a small, finger-like pouch called the appendix wraps itself around a section of the bowel. When this happens, the loop tightens like a noose, cutting off blood flow and causing the tissue to die. This condition, known as a strangulated obstruction, is a surgical emergency that can quickly lead to shock and death if the blockage is not removed. While doctors often look for scar tissue from past surgeries or hernias as the usual culprits behind such blockages, there are rare cases where the cause is hidden in a body that has never been operated on before.
A team of surgeons in Ethiopia recently documented one such rare and severe case involving a 52-year-old man who arrived at the hospital in critical condition. The patient had spent two days in severe pain, with a swollen belly, vomiting green fluid, and an inability to pass gas or stool. He was dehydrated, his heart was racing, and his blood pressure had dropped dangerously low, indicating that his body was going into shock. Because he had never had abdominal surgery, doctors initially considered common causes like a twisted intestine, but his condition was too unstable to wait for detailed imaging scans. The medical team decided that the only way to save him was to open his abdomen immediately to find and fix the source of the problem.
Upon entering the abdominal cavity, the surgeons found a massive amount of bloody fluid, a sign that tissue was dying inside. They discovered that the patient's appendix, which had become inflamed and grown to 16 centimeters in length, had wrapped itself tightly around the lower part of his small intestine. This knot had created a closed loop that strangled the bowel, cutting off its blood supply and causing about one meter of the intestine to turn black and gangrenous. The surgeons carefully untied the knot, removed the dead appendix, and cut out the damaged section of the intestine. Because the remaining healthy piece of intestine was too short to reconnect to the next section in the usual way, they attached the healthy end of the small intestine directly to the side of the large intestine, creating a new path for waste to pass through.
The patient survived the ordeal, though his recovery required intensive care and medication to support his blood pressure for two days. By the second day after surgery, his shock had resolved, and he began to eat and drink again. He was discharged a week later and remained healthy a month after the procedure. This case highlights that even in patients with no history of abdominal surgery, rare mechanical blockages can occur that require immediate surgical intervention. The surgeons noted that while computer scans are helpful for stable patients, they should not delay life-saving surgery when a patient is unstable and shows clear signs of a strangulated bowel. The report serves as a reminder that the appendix can sometimes act as an unexpected trap, turning a routine organ into a cause of life-threatening obstruction.
