Laparoscopic resection of ileocaecal duplication in children (report of 15 cases)

Ileocecal duplication in children: a single-center experience of 115 cases

To evaluate the clinical features, surgical management, and prognosis of ileocecal duplication in children. A total of 115 patients diagnosed with ileocecal duplication at Beijing Children's Hospital between January 2010 and June 2021 were retrospectively reviewed. Ileocecal duplications were divided into ileal intraluminal (n = 41), ileal extraluminal (n = 24), ileocecal valve (n = 11), cecal intraluminal (n = 18), and cecal extraluminal (n = 3) types according to their locations. Median age at diagnosis was 9.5 (0.1-169.2) months. Intussusception was only observed preoperatively in patients with the ileal intraluminal (8/41), ileocecal valve (4/11), and cecal intraluminal (7/18) types (P = 0.004). Ileocecal resection and ileocolostomy and cyst excision without ileocecal resection were performed in 41 (35.7%) and 74 (64.3%) patients, respectively. The proportions of cyst excision without ileocecal resection performed in patients with different types were 78.0% (32/41), 91.7% (22/24), 27.3% (3/11), 27.8% (5/18), and 100.0% (3/3) (P < 0.001). Time of oral intake (P = 0.003) and hospital stay after surgery (P < 0.001) were significantly shorter in patients undergoing cyst excision without ileocecal resection. There were no significant differences in the complications, growth, and stool frequency (older than 4 years) between patients undergoing different surgical procedures. Regarding the stool consistency (older than 4 years), there was a lower proportion of dry stool in patients undergoing cyst excision (P = 0.008).

CONCLUSIONS

Ileocecal duplications at specific locations are prone to intussusception and can influence the surgical procedure choice. At mid-term follow-up, the children's growth and defecation patterns do not seem to be affected by ileocecal resection.

WHAT IS KNOWN

• How to address ileocecal duplication has always been challenging in clinical management. • Children who have an ileocecal resection can develop some early postoperative complications.

WHAT IS NEW

• Ileocecal duplications at specific locations are prone to intussusception and can influence the surgical procedure choice. • Children's growth and defecation patterns do not seem to be affected by ileocecal resection.

Does Ileocecal Resection Affect Children's Medium-Long-Term Growth and Defecation Patterns? A Matched Case-Control Study

BACKGROUND

Ileocecal resection leads to some early complications, but it is unknown whether it affects children's medium-long-term growth and defecation patterns. To determine if there was an association, we conducted this matched case-control study.

METHODS

This study was conducted in Beijing Children's Hospital and included three groups: the case group (n = 30) included patients with ileocecal duplication undergoing ileocecal resection between January 2010 and June 2021, the control group (n = 90) included outpatient patients without ileocecal resection in January 2022, and the appendectomy group (n = 90) included patients who underwent appendectomy between January 2010 and June 2021. The 1:1 matching criteria included gender and age (within 1 year). The evaluation indicators were growth (height-for-age, BMI) and defecation patterns (stool frequency, stool consistency) over 6 months after surgery. Defecation patterns were assessed in patients older than 4 years. Stool consistency was evaluated by the modified Bristol Stool Form Scale.

RESULTS

There were no significant differences, except for stool consistency, between the case and control groups regarding their growth and defecation patterns before case-control matching. The patients in the case group had a significantly higher prevalence of dry stool (P < 0.008). After case-control matching, there were no significant differences in the growth and defecation patterns between the case and control groups. Before and after case-control matching, there were no significant differences in the defecation patterns between the control group and the appendectomy group.

CONCLUSION

Children's medium-long-term growth and defecation patterns were not affected by ileocecal resection.
