Endoscopic self-expandable metal stent placement for malignant afferent loop obstruction caused by peritoneal recurrence after total gastrectomy

Abstract

Afferent loop obstruction (ALO) caused by cancer recurrence after total gastrectomy (TG) can be managed by either surgical or non-surgical treatment. The general condition of patients with recurrent gastric cancer is often poor, so a less invasive non-surgical treatment is desirable. We report the case of a 75-year-old male who had undergone TG for gastric cancer 6months previously and who presented at our hospital with abdominal pain and vomiting. Abdominal computed tomography scan showed a dilated afferent loop, and additionally a low-density lesion around jejunojejunal anastomosis, suggesting that ALO is associated with peritoneal recurrence. A self-expandable metal stent (SEMS) was endoscopically placed to treat ALO after decompression of the dilated afferent loop using an intestinal tube. He retained a good quality of life until his death due to cancer progression 5months after the SEMS placement. Our case indicates that SEMS could be a less invasive alternative to surgery, and may confer a better quality of life for patients with ALO due to cancer recurrence after TG. This is the valuable report of case in which endoscopic metallic stent placement succeeded for ALO caused by peritoneal recurrence after TG.
