In laparoscopic cholecystectomies, ultrasound-guided interfascial plane blocks are commonly used for postoperative analgesia. The aim of our study was to compare the postoperative analgesic efficacy of thoracoabdominal nerve block with the perichondral approach (TAPA) with transversus abdominis plane (TAP) block in patients undergoing laparoscopic cholecystectomy.
Laparoscopic cholecystectomy (LC) is one of the most frequently performed surgical operations and the postoperative hospital stay is short (1). Although there is less postoperative pain in laparoscopic surgeries than in open surgeries, severe pain is a common complaint, especially in the first 24 hours. Therefore, various modalities have been tried to reduce postoperative pain (2). In recent years, the effectiveness of ultrasound-guided interfascial plane blocks has come to the fore in the field of regional anaesthesia and pain management. There has always been a search for a regional anaesthesia method that provides effective analgesia of the anterolateral part of the upper abdomen. In addition to anterolateral blocks, such as pectoralis nerve block (PECS) and serratus intercostal plane block (SIBP), other posterior blocks like quadratus lumborum blocks and erector spinus plane blocks have been used for this purpose. TAP block is the application of local anaesthetic agents into the neurofascial space between the internal oblique and transversus abdominis muscle layers located in the anterolateral region of the abdomen. This procedure, in which the anterior branches of the 7th-12th thoracic intercostal and first lumbar (L1) nerves are blocked, is frequently used to provide pain control after operations involving the abdominal and inguinal regions (3,4). Recently introduced thoracoabdominal nerve blockage with perichondrial approach (TAPA) has been reported to provide sensory blockade between midaxillary line and midabdominal/sternum in dermatomes between T5-T12 (5,6). In TAPA block, local anesthesia is applied to two points, the upper part of the chondrium and the lower part of the chondrium. In this way the anterior and lateral cutaneous branches of the intercostal nerves are blocked. In light of this information, our hypothesis is that the analgesic effect will be greater in TAPA block since the lateral branches of the intercostal nerves are also affected. The aim of our study is to compare the postoperative analgesic efficacies of TAP and TAPA blocks to be applied to patients undergoing laparoscopic cholecystectomy.

: It was performed under USG guidance using 30 ml of 0.25% bupivacaine with an 80 mm insulated peripheral block needle. Local anaesthetic was applied between the upper fascia of the transversus abdominus muscle and the fascia of the internal oblique muscle at the midpoint of the distance between the costal margin and the iliac crest in the midaxillary line under USG imaging guidance.
Under USG guidance, 20 ml of 0.25% bupivacaine was administered between the upper fascia of the transversus abdominis muscle and the lower fascia of the costochondral tissue at the level of the 9th and 10th ribs (arcus costarum) in the midclavicular line with an 80 mm insulated peripheral block needle. Then, 10 ml of 0.25% bupivacaine was injected into the upper fascia of the costochondral tissue and the lower fascia of the external oblique muscle. The block was performed by following the needle path in the ultrasound image.

postoperative analgesic efficacy
NRS (Numerical Rating Scale) was used for pain monitoring. Patients were informed about the NRS assessment for pain. It was stated that a score of 0 meant no pain and a score of 10 meant the worst pain imaginable. After the first assessment hour when NRS \>4 was noted in patients, IV analgesia treatment was started (dexketoprofen 50 mg IV as additional analgesic). If NRS \<4 and the patient did not request analgesic, the drug dose was skipped.
Time frame: At the postoperative 2nd, 6th, 12th and 24th hours, the patient's request and administrations from the patient-controlled analgesia (PCA) device, total tramadol dose and the first additional analgesic drug if needed, and application times were recorded.
