Laparoscopic Appendectomy: Outcomes of 10 mmHg Versus 15 mmHg Intra-abdominal Pressure
Comparison of Standard Pneumoperitoneum Pressures in Laparoscopic Appendectomy: Clinical Outcomes of 10 mmHg Versus 15 mmHg Intra-abdominal Pressure
Přehled studie
Postavení
Detailní popis
Laparoscopic appendectomy is the standard surgical treatment for acute appendicitis. Carbon dioxide pneumoperitoneum is essential for adequate visualization and operative exposure; however, the optimal intra-abdominal pressure remains controversial. Standard pneumoperitoneum pressures of 12-15 mmHg provide satisfactory visualization but may contribute to increased postoperative pain and adverse cardiopulmonary effects. Lower-pressure pneumoperitoneum has the potential to reduce postoperative discomfort but may increase technical difficulty during surgery.
This single-center, prospective, randomized controlled trial will be conducted at Ankara Etlik City Hospital. Adult patients undergoing laparoscopic appendectomy for acute appendicitis will be randomly assigned to undergo surgery with either 10 mmHg or 15 mmHg pneumoperitoneum. All other perioperative management and surgical techniques will be standardized.
The primary outcome is postoperative pain assessed using the Numeric Rating Scale (NRS). Secondary outcomes include operative time, conversion to open surgery, time to first flatus, time to first bowel movement, length of hospital stay, postoperative ileus, postoperative intra-abdominal abscess, emergency department readmission, and postoperative complications. Patients will be followed according to the institutional postoperative care protocol, including outpatient follow-up for the assessment of postoperative complications.
The results of this study are expected to provide evidence regarding the optimal pneumoperitoneum pressure during laparoscopic appendectomy by balancing surgical exposure with postoperative recovery and patient safety.
