Introduction: Oral intoxication with corrosive acid agents occurs by ingestion of acid, heavy metal salts (sublimate), formalin, iodine tincture and many other chemical substances.The extent of injury that results from corrosive ingestion is estimated by the depth of resultant corrosive burn. Case Report: We report a case of 22 year female with alleged history of corrosive acid ingestion with extensive necrosis of intra–abdominal organs in which ampullo jejunostomy was done for reconstruction. Discussion: Corrosive acid injury to the upper G.I. tract is a challenge to the surgeon.Emergency surgical intervention done in esophageal and gastric perforation,in case of transmural necrosis to avoid involvement of other organs and death.Transhiatalesophagectomy and total gastrectomy are the most common surgical procedures.
