The pattern of hydatid disease-a retrospective study from himachal pradesh, India.

Hydatid disease is a common but little studied disease in Himachal Pradesh, India. This is a retrospective study from the Lady Willingdon Hospital, Manali. 115 patients presenting from April 1996 to March 2007 were included. Outcome measures were mortality and morbidity. 70 patients were female and 46 were male. (One female patient was operated on twice). 78% (n = 90) of the occurrences were hepatic. There were other varied sites. There were fourteen pulmonary hydatids. All patients underwent surgical cystectomy. An "AIR Technique" (Aspiration, Injection, Reaspiration) is described for scolicidal deactivation after March 2003 utilized in thirty two patients. There was no mortality. There were five documented recurrences in our series all of which occurred in cystectomy done without the AIR (Aspiration, Injection, Reaspiration) technique. Hydatid disease is a common disease in Himachal Pradesh warranting a high index of suspicion leading to an early diagnosis. A simple technique called the "AIR TECHNIQUE" (Aspiration, Injection, Reaspiration) is described.
