Abstract:
Objective:To compare and analyze the effects of time-restricted feeding (TRF) and exercise intervention on postoperative outcomes in obese children with concealed penis following corrective surgery, and to identify more effective postoperative management strategies.Methods:A retrospective study was conducted on the clinical data of obese boys aged 6-12 years who underwent modified Devine surgery for concealed penis in the Department of Pediatric Surgery, the Second Affiliated Hospital of Shandong First Medical University, between October 1, 2022, and June 30, 2024. According to the postoperative weight management intervention, patients were divided into three groups: an exercise group, a TRF group, and a non-intervention group. The exercise and TRF groups received 6 months of structured exercise or TRF-based weight management, respectively. During TRF intervention, all caloric intake was confined to a 10-hour period each day, with no energy intake during the remaining 14 hours. Postoperative follow-up was conducted daily for 6 months. The preoperative suprapubic fat thickness (h1) and penile length (d1), immediate postoperative penile length (d2), and 6-month postoperative suprapubic fat thickness (h2) and penile length (d3) were measured. At 6 months after surgery, changes in body mass index (BMI), penile exposure increment (Δd = d3-d1), and suprapubic fat thickness were compared among the three groups. Statistical analyses were performed using SPSS version 27.0.1. Data conforming to a normal distribution were expressed as Mean ± SD. One-way analysis of variance (ANOVA) or Welch’s ANOVA was used for intergroup comparisons, followed by independent sample t-test and Bonferroni correction or Games-Howell tests for post hoc multiple comparisons when significant differences were identified. A P value < 0.05 was considered statistically significant. Results:A total of 101 male patients were enrolled: 35 in the exercise group, 31 in the TRF group, and 35 in the non-intervention group. No significant differences were observed among the three groups in age, preoperative BMI, h1, d1, or d2 (all P > 0.05), indicating comparable baseline characteristics. At 6 months postoperatively, the BMI of the TRF group was significantly lower than that of the exercise and non-intervention groups [(20.82±1.19) kg/m 2 vs. (22.46±2.00) kg/m 2 vs. (23.52±2.52) kg/m 2,P < 0.05]; the BMI in the exercise group showed a decreasing trend compared with the non-intervention group, although the difference was not statistically significant ( P>0.05); the penile exposure increment (Δd) was greater in the TRF group than in the exercise and non-intervention groups [(2.08±0.43) cm vs. (1.68 ± 0.37) cm vs. (1.47 ± 0.16) cm], while the suprapubic fat thickness (h2) was smaller [(8.65±1.96) mm vs. (10.43±1.32) mm vs. (11.26±1.53) mm]; the exercise group also demonstrated a larger Δd and a smaller h2 than the non-intervention group, and these differences were statistically significant (all P<0.05). Conclusion:Both TRF and regular exercise are effective postoperative weight management interventions for maintaining surgical outcomes in obese children with concealed penis after modified Devine surgery. Among these approaches, TRF demonstrates superior efficacy.
