Intussusception is primarily a disease of children and is the primary cause of intestinal obstruction in the pediatric age group. It accounts for around 5–16% of cases of intestinal obstruction in adults of the western population. Most cases of adult intussusception (up to 90%) are secondary to an identified structural lesion or a lead point contrary to pediatric intussusception. Adults with intussusception present with subacute or chronic symptoms of partial obstruction. CT is the best imaging to make a preoperative diagnosis of adult intussusception. The standard treatment for adult intussusception is surgery, and non-operative reduction should not be attempted. Here, we present a rare case of idiopathic small bowel intussusception in a 50-year-old woman. She presented with crampy abdominal pain for one-week duration. It was associated with frequent vomiting of bilious matter. She claimed to have had similar symptoms for the past 2 months and had repeatedly visited nearby health facilities. She had an abdominal CT, which suggested a complicated small bowel intussusception. Exploratory laparotomy was done, and there was a small bowel intussusception and an inflammatory stricture at the end of the intussusceptum, which is believed to form a closed-loop like obstruction. The intussusceptum was resected en-bloc then end-to-end jejuno-jejunal anastomosis was performed. This case report makes physicians aware of this rare condition in adults. So that they have a high index of suspicion when a patient presents with symptoms of subacute or chronic intestinal obstruction and inform that abdominal CT should be done in these circumstances and surgery is the mainstay of treatment. Our case is unique, and there is no report in the literature similar to ours.

Tuberculosis (TB) is a chronic granulomatous inflammatory disease that affects any part of our body. TB is a significant problem in developing countries. Intestinal TB accounts for 2% of TB cases worldwide. Terminal ileum and cecum are the two commonly affected regions because of abundant lymphoid tissue, physiologic stasis, limited digestive activity and increased fluid and electrolyte absorption rate. Intestinal obstruction is the leading complication of intestinal TB, and it occurs because of intestinal luminal narrowing, multiple strictures or adhesions. The clinical presentation of patients with intestinal TB and post-TB intestinal obstruction is non-specific. It can be acute, chronic, or acute on chronic. Uncomplicated cases of intestinal TB can be managed medically. Surgery is reserved for complicated cases of intestinal TB, which includes peritonitis, intestinal obstruction and perforations. Here, we present a 37-year-old man who presented with long-standing, intermittent crampy abdominal pain and vomiting. He was diagnosed with chronic partial small bowel obstruction secondary to possibly small bowel carcinoma. We did segmental ileal resection and end-to-end ileo-ileal anastomosis. Postoperatively, the histopathology result turned out to be intestinal TB. This case report aims to make physicians aware of the rare condition of small bowel obstruction secondary to intestinal TB. Clinicians need to have a high index of suspicion in any patient with long-standing symptoms of partial obstruction and consider surgery and anti-TB once diagnosed.
