Oblique Subcostal Tap Block Efficacy in Laparoscopic Cholecystectomy

• Status: Unknown status
• Trial end date: 2016-06-01
• Target enrollment: 0
• Participant gender: All

Summary

Laparoscopic cholecystectomy although a minimally invasive procedure, may be accompanied by considerable pain after surgery. More recently transversus abdominis plane (TAP) block was extensively studied as a potential analgesic maneuver after laparoscopic cholecystectomy. The subcostal approach (OSTAP block) is a variation on the TAP block that produces reliable supraumbilical analgesia.
