Clinical characteristics and treatment outcomes of symptomatic Meckel diverticulum: a comparative study among children, adolescent, and adult patients

Abstract

Purpose: We investigated the clinical characteristics and treatment outcomes of symptomatic Meckel diverticulum (MD) in adolescents by comparison with children and adults.

Methods: We retrospectively reviewed the medical records of patients who underwent symptomatic MD surgery from January 2002 to December 2019. Demographic information, clinical presentations, preoperative evaluations, operative variables, postoperative outcomes, and pathologic findings were collected. We performed analyses by dividing all patients into three groups according to age at surgery: child group (<10 years), adolescent group (10-19 years), and adult group (≥20 years).

Results: Forty-three patients underwent symptomatic MD surgery (the child group, 14; the adolescent group, 17; and the adult group, 12). Vomiting and intestinal obstruction decreased significantly with age (P = 0.042 and 0.001), whereas hematochezia and gastrointestinal bleeding showed an increasing trend with age, although not statistically significant (P = 0.064 and 0.064). Ultrasound performance decreased significantly with age (P = 0.002), whereas CT performance showed an increasing trend with age, although not statistically significant (P = 0.193). Preoperative diagnosis rate increased significantly with age (P = 0.029). Laparoscopic surgery was performed significantly more in the adult group than in other groups (P = 0.001). The sizes of MD were significantly greater in the adolescent group than in other groups (P = 0.006 and 0.002).

Conclusion: The clinical characteristics and treatment outcomes of symptomatic MD in adolescents exhibit a transitional pattern between children and adults. Therefore, it is important for clinicians to recognize that adolescent patients with symptomatic MD have the characteristics of both children and adult patients to ensure optimal care.
