Doctors at Thanh Hoa General Hospital on Nov 5 successfully operated on Laotian traffic policeman Thao Eng, who was in critical condition from esophagus bleeding.

According to the doctors, senior lieutenant Eng, 27, from Laos’ Hua Phan province which borders northern Thanh Hoa province’s Muong Lat district, was rushed to hospital one day earlier after he vomited blood profusely and had low blood pressure and fast pulse.

The doctors later detected a serious drop in Eng’s red blood cells and promptly gave him a blood transfusion before successfully conducting an endoscopic surgery on his esophagus.

Humans typically have four million red blood cells per liter of blood, but when Eng was hospitalized, he only had 1.94 million. Without timely medical intervention, he would have suffered an acute, life-threatening blood loss.

Eng is now recovering well at the hospital.
