Laparoscopic cholecystectomy is the gold standard for cholelithiasis, yet postoperative pain remains a clinical challenge. Ultrasound-guided transversus abdominis plane (TAP) block has been proposed as an effective analgesic strategy. The objective of this study is to evaluate the effectiveness of prophylactic bilateral TAP block in patients undergoing elective laparoscopic cholecystectomy.
A prospective, randomized clinical trial was conducted at the "Dr. Salvador Zubirán Anchondo" General Hospital in Chihuahua, where adult patients scheduled for elective laparoscopic cholecystectomy were included. The intervention group received an ultrasound-guided bilateral TAP block prior to incision, while the control group received conventional analgesic management. Pain intensity was assessed using the Numerical Rating Scale (NRS) at 2, 6, 12, and 24 hours postoperatively; opioid consumption and adverse events were also recorded.
272 studies on the registry are indexed under Cholecystitis; 46 are open to participants now.
This study's enrollment of 60 is below the median of 87 across 172 interventional studies indexed under Cholecystitis.

Exclusion Criteria:
Usual pain management
Drug: Analgesic
Ultrasound-guided bilateral TAP block prior to incision
Procedure: Analgesic transversus abdominal plane blockade (Bupivacaine)
Administration of any analgesic medication (e.g. paracetamol, diclofenac, etc.)
Ultrasound-guided bilateral TAP blockade before incision.
Post-operative abdominal pain
Discomfort or nociceptive signaling originating in the abdominal wall that occurs as a direct consequence of the surgical procedure. Pain intensity was assessed using the Numerical Rating Scale (NRS) at predefined postoperative intervals (2, 6, 12, and 24 hours).
Time frame: From the end of the surgical procedure and for up to 24 hours
Opioid consumption
The cumulative amount of opioid medication the patient takes during a specific recovery timeframe following the surgical procedure
Time frame: From the end of the surgical procedure and for up to 24 hours
Nausea/Vomiting
A common side effect of surgery and anesthesia defined as any nausea, retching, or vomiting that happens within the first 24 to 48 hours after a procedure
Time frame: From the end of the surgical procedure and for up to 24 hours
