Small bowel diverticulum with enterolith causing intestinal obstruction: A case report

BACKGROUND Small bowel diverticula are rare in clinics,and small intestinal obstruction caused by coprolites is rarer and difficult to diagnose early.The true incidence of these diverticula may be underestimated due to their clinical symptoms not differing from those of small bowel obstruction resulting from other causes.It is common in the elderly,although it can occur at any age.CASE SUMMARY This is a case report of a 78-year-old man with epigastric pain for 5 d.Conservative treatment does not effectively relieve pain,inflammatory indicators are elevated,and computed tomography suggests jejunal intussusception and mild ischemic changes in the intestinal wall.Laparoscopic exploration showed that the left upper abdominal loop was slightly edematous,the jejunum mass at the near Flex ligament was palpable,the size was about 7 cm×8 cm,the local movement was slight,and the diverticulum was seen 10 cm downward,and the local small intestine was dilated and edema.Segmentectomy was performed.After the short parenteral nutrition after surgery,the fluid and enteral nutrition solution were pumped through the jejunostomy tube,and the patient was discharged after the treatment was stable,and the jejunostomy tube was removed in an outpatient clinic one month after the operation.Postoperative pathology:Jejunectomy specimen:(1)Small intestinal diverticulum with chronic inflammation,ulcer with full-thickness activity,and necrosis of the intestinal wall in some areas;(2)also see that the hard object is consistent with stone changes;and(3)the incision margin on both sides shows chronic inflammation of mucosal tissue.CONCLUSION Clinically,the diagnosis of small bowel diverticulum is difficult to distinguish from jejunal intussusception.Combined with the patient’s condition,rule out other possibilities after a timely disease diagnosis.According to the patient’s body tolerance adopt personalized surgical methods to achieve better recovery after surgery.
