Primary sclerosing cholangitis (PSC) is a progressive, cholestatic liver disease, and liver transplantation (LT) is considered the only therapeutic option for patients with end-stage liver disease secondary to PSC. Intestinal obstruction in adults after LT surgery is a rare complication with diverse clinical presentations. The most common etiology is intestinal adhesions, but this can also result from other rare causes such as enterolith. We describe the first case report of small bowel obstruction secondary to biliary stone formation in the common limb of Roux-en-Y hepaticojejunostomy 13 years after the deceased donor LT. The patient failed initial conservative management and developed peritonitis, requiring urgent surgical exploration to remove the enterolith and resect the involved small bowel. In conclusion, small bowel obstructions due to enteroliths are unusual clinical complications following LT, which require a high degree of suspicion in patients who develop a bowel obstruction in the setting of a previous hepaticojejunostomy.

Enterolithiasis is an uncommon medical condition. It's defined by the formation of gastrointestinal concretion in the setting of intestinal stasis. Enteroliths are typically incidentally discovered during imaging and are a rare cause of acute small bowel obstruction. We report the case of acute small bowel obstruction, secondary to primary true enterolithiasis, in a 73-year-old male, with unremarkable medical history. He presented with clinical features in keeping with acute small bowel obstruction, for 2 days. An abdominal contrast-enhanced CT scan suggested a small bowel obstruction caused by a 32mm diameter enterolith located in the terminal ileum. The surgical management was successful and consisted of the removal of the enterolith after enterotomy.

True primary enterolithiasis is an uncommon condition, and nontraumatic perforation of the small intestine (NTPSI) is also an unusual entity. Therefore, NTPSI due to true primary enteroliths is an exceptionally rare complication. Moreover, enterolithiasis and radiation enteritis are also unique combinations. Herein, we present an exceedingly rare case of NTPSI induced by multiple true primary enteroliths associated with radiation enteritis.

A 92-year-old woman with acute abdominal pain was transferred to our hospital because a computed tomography (CT) scan performed by her family doctor revealed free air and fluid collection within her abdomen. Our initial diagnosis was upper gastrointestinal perforation, and we selected nonoperative management (NOM) with adnominal drainage. Although her general condition was stable, jejunal juice was drained continuously. Given that the CT performed 10 days after onset demonstrated perforation of the small intestine and adjacent concretion, we performed an emergency partial resection of the small intestine and jejunostomy. The resected bowel was 1 m in length and had many strictures that contained multiple enteroliths in their proximal lumens. The patient’s postoperative course was uneventful. The enteroliths were composed of deoxycholic acid (DCA). She was diagnosed with peritonitis due to NTPSI derived from multiple true primary enteroliths associated with radiation enteritis, as she had previously undergone hysterectomy and subsequent internal radiation therapy.

Clinicians should consider the rare entity of true primary enteroliths associated with radiation enteritis in NTPSI cases with unknown etiologies.

Primary enterolithiasis is a relatively uncommon but important cause of small bowel obstruction. We present a case of a 69-year-old male with a history of laparoscopic Roux-en-Y gastric bypass and asymptomatic duodenal diverticulum diagnosed with small bowel obstruction. CT imaging showed an obstruction distal to the jejunojejunostomy, and surgical intervention was warranted. A 4.5 cm enterolith removed from the distal jejunum was found to contain 100% bile salts, consistent with a primary enterolith. Clinicians should retain a high index of suspicion for enteroliths as a cause of small bowel obstruction, especially if multiple risk factors for enterolith formation are present.

Small bowel obstruction is a common surgical emergency. The common causes are adhesions, malignancies, and hernias. We present a rare case of small intestinal obstruction caused by an enterolith in the distal ileum in a patient with an apparently normal gut. 

A 59-year-old male who underwent gastrojejunostomy 15 years back presented with features of intestinal obstruction of five days' duration. After initial conservative management, the patient was taken up for laparotomy. An enterolith causing obstruction was found in the distal ileum, and it was crushed and milked into the colon. The patient made an uneventful recovery. 

The chyme crossing the ileum is usually liquid or semi-solid and hence luminal obstruction by the faecal bolus in the ileum is very unusual. In patients with previous gastric surgeries where the pylorus is bypassed, the solid food particles enter the small intestine and can form a bezoar. This patient was managed with laparotomy and milking of the stool bolus into the colon. Other treatment options include enterotomy or resection of the diseased bowel and removal of the enterolith. 

Small bowel obstruction due to an enterolith is very rare and can pose a diagnostic challenge.

Enterolithiasis or formation of gastrointestinal concretions is an uncommon medical condition that develops in the setting of intestinal stasis in the presence of the intestinal diverticula, surgical enteroanastomoses, blind pouches, afferent loops, incarcerated hernias, small intestinal tumors, intestinal kinking from intra-abdominal adhesions, and stenosing or stricturing Crohn’s disease and intestinal tuberculosis. Enterolithiasis is classified into primary and secondary types. Its prevalence ranges from 0.3% to 10% in selected populations. Proximal primary enteroliths are composed of choleic acid salts and distal enteroliths are calcified. Clinical presentation includes abdominal pains, distention, nausea, and vomiting of occasionally sudden but often fluctuating subacute nature which occurs as a result of the enterolith tumbling through the bowel lumen. Thorough history and physical exam coupled with radiologic imaging helps establish a diagnosis in a patient at risk. Complications include bowel obstruction, direct pressure injury to the intestinal mucosa, intestinal gangrene, intussusceptions, afferent loop syndrome, diverticulitis, iron deficiency anemia, gastrointestinal hemorrhage, and perforation. Mortality of primary enterolithiasis may reach 3% and secondary enterolithiasis 8%. Risk factors include poorly conditioned patients with significant obstruction and delay in diagnosis. Treatment relies on timely recognition of the disease and endoscopic or surgical intervention. With advents in new technology, improved outcome is expected for patients with enterolithiasis.
