Gastric outlet obstruction in adults is usually caused by pyloric stenosis secondary to peptic ulcer disease or malignancy. However, there are few other causes such as a foreign body and external compression due to pseudocyst pancreas. We present a rare aetiology of a large collection of pus in the lesser sac in our patient causing gastric outlet obstruction. A perforated peptic ulcer was suspected in our patient who had symptoms of sudden onset pain in epigastric region which was referred to back. This was followed by pain in upper abdomen, vomiting, constipation and fever for which patient was being managed conservatively before being referred to us. The CECT didn`t show any leakage of contrast to the lesser sac making the possibility of healed perforation likely as all other causes were ruled out at the time of presentation to our hospital. The CECT scan ruled out other causes of gastric outlet obstruction with normal wall thickness of the stomach and duodenum along with normal looking liver, pancreas and no lymphadenopathy. The liver function tests and serum amylase were within normal limits. Along with this, there was another unrelated rare coincidental finding of aortoiliac occlusive disease termed as Leriche`s syndrome. Ultrasound guided percutaneous drainage was done following which the patient`s obstruction was relieved and patient was referred to the department of vascular surgery for the mangement of aortoiliac occlusive disease.
