Acute appendicitis is one of the most common emergency general surgical conditions worldwide and represents the leading cause of emergency abdominal surgery in children. In some cases, appendectomy may result in persistent or recurrent pain in the right iliac fossa, which may negatively affect quality of life, particularly in children. The primary aim of this study is to determine the prevalence of chronic pain at the third postoperative month in pediatric patients who underwent appendectomy. The age, sex, body mass index, and comorbidities of patients aged 8-18 years who underwent appendectomy will be recorded. Pain in children who met the inclusion criteria was assessed using the Numeric Rating Scale (NRS). To evaluate the effects of pain on quality of life, the child and parent versions of the Pediatric Quality of Life Inventory (PedsQL) were administered at the third postoperative month. In addition, the Functional Disability Inventory (FDI) was used at the third postoperative month to assess the impact of pain on the patient's functional status.

Acute appendicitis is one of the most common surgical emergencies in childhood, with appendectomy being the standard and most frequently performed emergency surgical treatment. Although appendectomy is generally considered a safe and routine surgical procedure, various postoperative complications such as surgical site infection, intra-abdominal adhesions, abscess formation, and nerve injury may occur. In addition to these well-known complications, some patients may experience persistent or recurrent pain following surgery. Chronic postsurgical pain (CPSP) is defined as pain that develops or increases in intensity after a surgical procedure and persists beyond the healing process (for longer than 3 months), localized to the surgical site or radiating to the related area. CPSP in children is associated with adverse psychological outcomes such as depressive mood and anxiety, restricted functionality including avoidance of daily activities and decreased school attendance, and poorer health outcomes (1).

After approval from the Local Ethics Committee was obtained, records of children aged 8-18 years who underwent appendectomy, including age, sex, ASA score, and type of surgical procedure, were obtained by reviewing the hospital information system and anesthetic records. The inclusion criteria were defined as children aged 8-18 years, patients classified as ASA I-II, and children who agreed to participate in the study. Patients with an ASA score of 3 or higher, a history of another operation in the right lower quadrant of the abdomen, chronic abdominal pain in the preoperative period, or psychiatric disorders were excluded from the study. At the third postoperative month, patients will be contacted by telephone to assess chronic pain, quality of life, and functional status. The primary endpoint of this study is to determine the prevalence of chronic pain at the third postoperative month in pediatric patients who underwent appendectomy. The secondary endpoints are to investigate the effects of surgical technique and patient characteristics on chronic pain, as well as the impact of chronic pain on quality of life and functional status in pediatric patients.

Pain is defined as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage," and is described as a personal experience influenced to varying degrees by biological, psychological, and social factors. Children were asked whether they experienced pain at rest or during exercise. Pain was evaluated using the Verbal Numeric Rating Scale (VNRS). The effects on quality of life at the third postoperative month were assessed using the Pediatric Quality of Life Inventory (PedsQL) parent and child forms, while the impact on functionality was evaluated using the Functional Disability Inventory (FDI).

Inclusion Criteria:

Children between the ages of 8-18 years who underwent appendectomy, who had ASA physical status I-II

Exclusion Criteria:

Children who aged under 8 and over 18 years, who had American Society of Anesthesiologists (ASA) physical status III or higher, who had a history of previous surgery in the right lower abdominal quadrant, who had psychiatric disorders, who had preoperative chronic abdominal pain

Pediatric patients who underwent appendectomy for acute appendicitis at Kocaeli City Hospital will be recruited for this study.
