Brief summary: Cholecystectomy is a widespread surgical procedure performed worldwide for acute cholecystitis. This operation can be performed using open surgery or laparoscopic techniques. Laparoscopic technique is superior to open surgery in terms of less pain at incision sites, shorter hospital stay, improved quality of life, and faster recovery times.However, despite being a minimally invasive surgery, laparoscopic cholecystectomy (LC) can still cause moderate to severe pain. Severe pain can lead to delayed postoperative ambulation, decreased patient satisfaction, the development of chronic pain, and is associated with increased lung and heart complications. Postoperative pain in LC can stem from various causes. To reduce the postoperative pain caused by LC, non-steroidal anti-inflammatory drugs, paracetamol, opioids, local anesthetics, and various regional anesthesia techniques are used.Multimodal analgesia has shown that the use of regional anesthesia and analgesia is crucial in reducing the neuroendocrine stress response in pain and trauma situations. The use of interfascial plane blocks performed under ultrasound guidance in LC surgery, considered easy and safe, has increased in recent years. The thoracoabdominal plane block (TAPA) applied through a perichondrial approach reaches a broader dermatomal area than the transversus abdominis plane (TAP) block and the oblique subcostal transversus abdominis plane (OSTAP) block.Serratus intercostal plane block (SIPB) has been found effective for somatic analgesia in a case series after gastrectomy and cholecystectomy surgeries. Subsequent studies have indicated the effectiveness of SIPB for open upper abdominal surgeries. Rectus sheath block (RSB) is used to provide postoperative analgesia after various surgeries, including laparoscopic and upper abdominal surgeries. Ultrasound-guided RSB in LC has significantly reduced postoperative pain.In this study, similar to the combination of RSB and SIPB was planned to be applied to enhance the effectiveness and quality of analgesia in the mid-abdomen. A group in LC surgery was administered bilateral M-TAPA, while another group received bilateral RSB + right SIPB, aiming to compare the postoperative analgesic effectiveness.

Detailed description: The gallbladder is a small organ located in the right upper quadrant of the abdomen. Bile, which aids in the digestion of food, is collected in this organ. Gallstones are solid particles that form as a result of changes in the composition and concentration of bile caused by hormones, medications, diet, and weight changes. Sometimes, gallstones that form can block the normal flow of bile by exiting the gallbladder, leading to a condition known as acute cholecystitis when the cystic duct is obstructed by a gallstone. This condition causes distension and inflammation of the gallbladder.

Cholecystectomy is a common surgical procedure performed worldwide for acute cholecystitis. The management of acute cholecystitis is divided into medical and surgical approaches. Medical management includes bed rest, analgesic agents, antibiotic therapy, and intravenous fluid replacement. Surgical management involves a procedure called cholecystectomy, which is the surgical removal of the gallbladder. This operation can be performed using open surgery or laparoscopic techniques. The laparoscopic technique is superior to open surgery in terms of less pain at incision sites, shorter hospital stay, improved quality of life, and faster recovery times. However, laparoscopic cholecystectomy (LC), despite being a minimally invasive surgery, can still cause moderate to severe pain.

Severe pain can lead to delayed postoperative ambulation, decreased patient satisfaction, the development of chronic pain, and is associated with increased lung and heart complications. Postoperative pain in LC can arise from various causes. While a significant portion of postoperative pain in LC is attributed to incision sites (50-70%), it also originates from pneumoperitoneum (20-30%) and cholecystectomy (10-20%). Multimodal analgesia, including non-steroidal anti-inflammatory drugs, paracetamol, opioids, local anesthetics, and various regional anesthesia techniques, should be considered for pain control. Opioids may cause side effects such as postoperative nausea and vomiting (PONV), constipation, and respiratory depression. Neuraxial analgesia is rarely used in LC due to possible complications and technical difficulties.

The use of interfascial plane blocks under ultrasound guidance, considered easy and safe, has increased in LC surgery. The thoracoabdominal plane block (TAPA) applied through a perichondrial approach, showing that it spreads to a broader dermatomal area than the transversus abdominis plane (TAP) block and the oblique subcostal transversus abdominis plane (OSTAP) block. The rectus sheath block (RSB) is used to provide postoperative analgesia after various surgeries, including laparoscopic and upper abdominal surgeries. Ultrasound-guided RSB in LC has significantly reduced postoperative pain.

In this study, the combination of RSB and SIPB was planned to be applied to enhance the effectiveness and quality of analgesia in the mid-abdomen. Patients will be asked to fill out the Quality of Recovery-15 (QoR-15) scale, a self-report questionnaire used to assess the quality of postoperative recovery, in the preoperative waiting area on the morning of the surgery and 24 hours after the surgery. The QoR-15 scale measures recovery quality in five areas: physical comfort, pain, physical independence, psychological support, and emotional state, providing a one-dimensional measurement of recovery quality with scores ranging from 0 to 150. A higher score indicates better recovery quality.

In this study, in laparoscopic cholecystectomy, one group will receive bilateral M-TAPA, and another group will receive bilateral RSB + right SIPB to investigate their superiority in terms of postoperative NRS (Numeric Rating Scale) score, opioid consumption, dermatomal spread, PONV score, and complications, aiming to determine which is more effective.
