Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Objective The aim of this study is to compare the analgesic efficacy of bilateral subcostal transversus abdominis plane (TAP) and modified thoracoabdominal (M-TAPA) blocks in reducing intraoperative opioid consumption and postoperative analgesic needs in patients undergoing laparoscopic sleeve gastrectomy (LSG). This will be a retrospective study conducted at Haseki Training and Research Hospital between January and November 2024. The study will include patients with a Body mass index (BMI) greater than 35 kg/m², aged between 18 and 65, who are scheduled to undergo LSG surgery. Patients will receive either a subcostal TAP or M-TAPA block before surgery. Data will be collected from patient records, including intraoperative opioid usage, postoperative analgesic consumption, and pain scores (NRS) assessed at rest and during activity in the first 24 hours. Secondary outcomes will include mobilization times and incidence of postoperative nausea and vomiting (PONV).

Objective The aim of this study is to compare the analgesic efficacy of bilateral subcostal transversus abdominis plane (TAP) and modified thoracoabdominal (M-TAPA) blocks in reducing intraoperative opioid consumption and postoperative analgesic needs in patients undergoing laparoscopic sleeve gastrectomy (LSG).

Study Design This will be a retrospective study conducted at Haseki Training and Research Hospital between January and November 2024. The study will include patients with a BMI greater than 35 kg/m², aged between 18 and 65, who are scheduled to undergo LSG surgery. Patients will receive either a subcostal TAP or M-TAPA block before surgery. Data will be collected from patient records, including intraoperative opioid usage, postoperative analgesic consumption, and pain scores (NRS) assessed at rest and during activity in the first 24 hours. Secondary outcomes will include mobilization times and incidence of postoperative nausea and vomiting (PONV).

Study Procedures Patients who meet the inclusion criteria will be included in the study, and data will be retrospectively reviewed. Intraoperative hemodynamic data, surgical duration, and total opioid consumption will be collected from anesthesia records. Postoperative analgesic use and pain scores will be assessed from nurse documentation and medical records. Patients with incomplete data or pre-existing chronic pain conditions will be excluded.

Outcome Measures

* Primary Outcome: Comparison of the analgesic efficacy of M-TAPA and subcostal TAP blocks during intraoperative and postoperative periods (first 24 hours).
* Secondary Outcomes: Resting and active NRS pain scores, mobilization times, incidence of nausea and vomiting, and complications related to the block procedures.
