Malignant obstruction in the ileocecal region treated by selfexpandable stent placement under the fluoroscopic guidance: A case report

BACKGROUND Malignant tumors of the ileocecal region often cause intestinal obstruction.Emergency surgery is the main treatment for patients presenting with an obstruction.However,this procedure is associated with a high mortality rate and frequent complications.The placement of colon stents is commonly performed for obstructions in the distal colon and is a less invasive and safer procedure.However,obstructions in the proximal colon are more challenging to treat by stent placement due to the increased distance from the anus.CASE SUMMARY This case report concerns an 88-year-old man with malignant intestinal obstruction in the ileocecal region.He was contraindicated for general anesthesia and surgical enterostomy.The placement of a self-expandable metallic stent seems an alternative to surgery,although stenting in this area is thought to be difficult and few studies have been reported so far.After three attempts at different interventional approaches,a stent was successfully placed in the obstructed segment under fluoroscopic guidance.After the procedure,the patient's abdominal distension and abdominal pain were significantly better than before.CONCLUSION For patients with proximal colonic obstruction,self-expandable metallic stent placement under fluoroscopic guidance could be considered as a feasible treatment to relieve abdominal distension and pain in patients with acute bowel obstruction.It has the characteristics of high safety and high patient tolerance.However,further study is still needed.

Decompression of the small bowel by endoscopic long-tube placement

AIM:To investigate and compare the decompression effect on small bowel obstruction of a long tube inserted using either endoscopic or fluoroscopic placement.METHODS:Seventy-eight patients with small bowel obstruction requiring decompression were enrolled in the study and divided into two groups.Intubation of a long tube was guided by fluoroscopy in one group and by endoscopy in the other.The duration of the procedure and the success rate for each group were evaluated.RESULTS:A statistically significant difference in the mean duration of the procedure was found between the fluoroscopic group(32.6±14.6 min)and the endoscopic group(16.5±7.8 min)among the cases classified as successful(P<0.05).The success rate was significantly different between the groups:88.6%in the fluoroscopic group and 100%in the endoscopic group(P <0.05).CONCLUSION:For patients with adhesive small bowel obstruction,long-tube decompression is recommended and long-tube insertion by endoscopy was superior to fluoroscopic placement.
