Enterolithiasis-Induced Intestinal Obstruction: A Single-Center Retrospective Series of Six Cases and Comprehensive Review of Literature
This retrospective study of six cases and a literature review highlights that enterolithiasis, though rare, is a significant cause of intestinal obstruction with diverse etiologies such as gallstone ileus and intestinal strictures, emphasizing the critical role of contrast-enhanced CT in diagnosis and the necessity of tailored surgical management.

Imagine your digestive system as a bustling, high-speed train network. The tracks are your intestines, and the cargo is the food you eat, moving smoothly from one station to the next. Usually, this system runs on autopilot, but sometimes, a rogue object gets stuck on the tracks, bringing the whole line to a screeching halt. In the world of medicine, these rogue objects are called enteroliths. Think of them as hard, rocky pebbles that form inside the gut itself, or perhaps as boulders that fall in from a nearby cliff (like a gallstone slipping from the gallbladder through a hole). When these stones get too big to pass, they cause a mechanical intestinal obstruction—a fancy way of saying the train has hit a brick wall. This isn't just a minor delay; it's a medical emergency that can cut off blood flow to the gut, causing serious damage. Doctors need to know exactly what kind of "pebble" is stuck and why it got there to fix the problem without making things worse.
This paper tells the story of six women who walked into a hospital in New Delhi with their digestive trains completely blocked by these mysterious stones. The doctors, led by Dr. Shashank Agrawal, looked back at their records from 2019 to 2022 to figure out what happened. They found that these stones didn't all come from the same place. Some were like "homegrown" rocks that formed because the gut had a narrow spot (a stricture) or a blind pocket where food got stuck and hardened. Others were "invaders"—gallstones that had escaped the gallbladder through a fistula (a weird, accidental tunnel) and rolled right into the intestine. The team used special X-ray scans (called CECT) to spot the stones before surgery, acting like a detective using a metal detector to find buried treasure.
The results were a mix of the expected and the shocking. In three of the six cases, the culprit was a gallstone that had made a break for it from the gallbladder. In one case, the stone was caused by a hidden infection called intestinal tuberculosis, which had scarred the gut and created a trap. But the most surprising discovery was in one patient: while the doctors were removing a stone from a narrowed section of the intestine, they found a tiny, hidden tumor (a low-grade appendicular mucinous neoplasm) hiding right next to it, like a surprise guest at a party. The treatment wasn't one-size-fits-all. Sometimes, they just had to cut out the stone. Other times, they had to remove a whole section of the intestine or even the gallbladder. Tragically, one patient passed away a week after surgery due to a sudden heart issue, showing how dangerous these blockages can be, especially for older or sicker patients.
The big takeaway from this story is that there is no single rulebook for fixing these blockages. The doctors learned that you have to be a master tailor, stitching together a plan that fits the specific stone, the specific reason it got stuck, and the specific health of the patient. If you just pull the stone out but ignore the narrow tunnel that caught it, the problem will likely come back. If you ignore a hidden infection or a sneaky tumor, you might miss a bigger danger. By using high-tech scans to see the whole picture before making a single cut, surgeons can save lives and avoid the worst outcomes. This paper suggests that while these stone blockages are rare, they are tricky puzzles that require a sharp eye and a flexible mind to solve.
