We read the clinical review on Inguinal Hernias by Jenkins and O’Dwyer,
and sincerely applauded their insightful recommendation that all medically fit patients with an inguinal hernia should have it repaired (1) Inguinal hernias account for 75% of abdominal wall hernias, with a lifetime risk of 27% in men and 3% in women.(1)
An inguinal hernia isn't necessarily dangerous always. However, if it doesn't improve on its own, or if patients aren't able to push the hernia in, the contents of the hernia can be trapped (incarcerated) in the abdominal wall. An incarcerated hernia can become strangulated, which cuts off the blood flow to the tissue that's trapped and can lead to life-threatening complications.
Excruciating pain due to ischaemic changes in entrapped gastrointestinal tissue may endanger life causing neurogenic shock. If surgical interventions are delayed, toxic materials from strangulated gut may spread and cause further deterioration of the patient’s overall general condition. Such irreversible complications may often ensue sudden unexpected death in elderly patients.
Less expensive watchful waiting under periodic evaluation, may be a popular endeavour among young patients with inguinal hernia to postpone surgical interventions and also to differ certain uncomfortable postoperative events like sexual dysfunction. (2, 6)
However, repair of inguinal hernia is one of the most common operations in general surgery, with rates ranging from 10 per 100 000 of the population in the United Kingdom to 28 per 100 000 in the United States (1).
Ironically, there is no definite sign for early detection of strangulation of herniated tissue in inguinal hernia and therefore, it seems difficult for patients or their relatives to ascertain when to terminate “watchful waiting period” and decide to seek surgical procedures for remote rural area patients in particular. (3) A third of patients scheduled for surgery have no pain, and severe pain is uncommon (1.5% at rest and 10.2% on movement) (1)
Moreover, there are reports about postoperative death of strangulated inguinal hernia patients who most commonly report for lifesaving surgical intervention late. (4) Postoperative mortality after elective and emergency surgery for inguinal hernia has also been reported (5).
Sudden unwitnessed, unexpected deaths when the bodies are found in public places require a complete and meticulous medico-legal autopsy to ascertain the cause and manner of death to avoid further unnecessary investigations by the legal authorities (7, 8).
