title: Trocar introduction performed during laparoscopy of the obese patient.
abstract: Obesity, especially morbid obesity, is reported to be a relative contraindication to laparoscopy. A technique for trocar introduction and laparoscopy of the obese patient to eliminate this contraindication is described. The technique presented herein differs from the traditional method by: 1, primary trocar entry at a 90 degree angle to the horizontal plane, and 2, confirmation for intraperitoneal position of the instruments before creating the pneumoperitoneum. A retrospective study was done to compare demographic, medical and surgical data of obese and non-obese patients. No important differences were found and it was also found that obesity was not a relative contraindication to laparoscopy. Obesity was defined by a ponderal index of less than 11.7. No operative complications were found for the 344 obese patients studied and all laparoscopy procedures were completed as intended. These differences in technique can avoid the pitfalls commonly reported concerning laparoscopy of the obese patient.
