Inguinal hernias occur when a loop of intestine pushes through the abdominal wall and down into the inguinal canal in the groin, either because of an inborn weakness or excessive strain. The result is a bulge that is usually painless in its first stages, but that might lead to pain and complications on later. Men are tenfold much more likely than women to have the condition. One plus of laparoscopy is certainly that it allows the surgeon to put the mesh within the abdominal wall structure, where it could be held set up by the natural outward pressure of the abdomen. Laparascopy also enables the surgeon to check for hernias elsewhere in the abdomen. With either method, most patients go back home after a couple of hours.Methods Study Participants Data on all infants who have had received a transplant for SCID in each of 25 centers between January 1, 2000, and December 31, 2009, were reviewed centrally. Of the 285 infants who met the requirements for SCID, the 240 infants with traditional SCID who had undergone allogeneic hematopoietic-cell transplantation were included in the study . Coded data were entered into an electronic database with institutional-review-board authorization at all centers.27,28 Transplants We recorded age group at transplantation, infection status, conditioning routine, donor type, degree of HLA match, cell source, method of T-cell depletion, and graft-versus-web host disease prophylaxis. Infection position was categorized as no infections before transplantation, contamination resolved before transplantation, and active infection during transplantation.
