- Chronic obstructive pulmonary disease,
- Obstruction to free flow of urine due to various causes or
- Intra-abdominal rise of pressure due to pathology inside the abdomen.
Hernia contents mainly comprises of intestines, a fatty intra-abdominal apron called omentum; and sometimes urinary bladder and other organs. Complications usually arise due to obstruction to the flow of blood to intestine and obstruction to passage of semi-digested food matter in the lumen of intestine. This occurs due to squeezing action tissue surrounding the potential space through which the hernia sac with contents passes out. There may be death or gangrene of the organs contained in the sac, to be called as a strangulated hernia. Emergency surgery is conducted on such patients and the contents returned inside the abdomen, if can be saved; otherwise are sacrificed to save the life of the patient. Such emergency unscheduled surgeries have inherent problems associated with anaesthesia and general fitness to undergo such procedure.
It is better said; “A stitch in time saves nine”.
