Alarming Incidence of Gastric Outlet Obstruction Related to NSAIDS and Synthetic Opioid in North West India.

ABSTRACT

BACKGROUND: In recent years, there has been an alarming increase in cases of gastric outlet obstruction (GOO) at our center due to drug abuse. So, we conducted this study to know the incidence of nonsteroidal anti-inflammatory drugs (NSAIDs) and synthetic opioid abuse in cases of GOO. METHODS: This was an observational study involving consecutive cases of GOO diagnosed from September 2017 to February 2019. A detailed history, including drug addiction history and clinical examination, was done. Investigations included routine biochemical and hematological tests, upper gastrointestinal endoscopy (UGIE), ultrasonography, rapid urease test (RUT), and histopathology of the diseased area. RESULTS: Among the 102 cases diagnosed with GOO, 62 (60.78%) cases had a history of drug addiction. The drug addiction history was as follows NSAIDs and opioids in 56, opioids alone in four, and NSAIDs alone in two cases. The most common site of stricture was the second part of the duodenum. The features on histopathology were ulcerations of the mucosa infiltrated by eosinophils, plasma cells, and lymphocytes. CONCLUSION: There is an alarming increase in the incidence of GOO due to NSAIDs and opioid abuse at our center. Efforts should be made to control the indiscriminate use of these over-the-counter drugs to prevent dreaded complications.
