Randomized control trial on effectiveness and safety of direct trocar versus Veress needle entry techniques in obese women during diagnostic laparoscopy.

Purpose: To determine the benefits and safety of direct trocar insertion versus Veress needle technique in obese women undertaking diagnostic laparoscopy procedures.

Methods: Randomized-controlled trial on 135 obese women undergoing diagnostic laparoscopy and dye test for infertility was conducted. Women were randomly assigned to either direct trocar access (n = 68) or Veress needle access (n = 67) before achieving pneumoperitoneum.

A Randomized Controlled Trial on Efficacy and Safety of Trocar-Site Infiltration with Lidocaine for Postoperative Pain Relief after Diagnostic Laparoscopy.

Background/aims: To compare the efficacy and safety of trocar-site infiltration with lidocaine and no intervention for postoperative pain relief after diagnostic laparoscopy.

Methods: A randomized clinical trial of women with infertility scheduled for diagnostic laparoscopy without additional procedures in Life Institute for Endoscopy at Life Specialist Hospital, Nnewi, Nigeria. One hundred and ninety nine women were assigned at random to either trocar-site infiltration with lidocaine (n = 100) or no intervention (n = 99).
