Spigelian hernia the morbidity and cost associated with foreign material. Adriaan van den Spiegel, a surgeon-anatomist born in Brussels, described this hernia. The first publication was in 1645, twenty years after Spiegel's death. Dr. Raveenthiran of SRM Hospital, Kattankulathur described a new syndrome in which Spigelian hernia and cryptorchidism (undescended testis) occur together. Spigelian hernia A Spigelian hernia (or lateral ventral hernia) is a hernia through the Spigelian fascia, which is the aponeurotic layer between the rectus abdominis muscle medially, and the semilunar line laterally.

Human body and about 23 litres of fluid inside cells. The content, acidity and composition of the water inside and outside cells is carefully maintained. The main electrolytes in body water outside cells are sodium and chloride, whereas within cells it is potassium and other phosphates. The body contains trillions of cells, the fundamental unit of life. At maturity, there are roughly 30–37 trillion cells in the body, an estimate arrived at by totalling the cell numbers of all the organs of the body and cell types. The body is also host to about the same number of non-human cells as well
