Results of rectoanal manometry after a novel laparoscopic technique: laparoscope-assisted heart-shaped anastomosis for Hirschsprung's disease

Post-operative anorectal manometry in children with Hirschsprung disease: A systematic review

BACKGROUND

Hirschsprung disease is commonly encountered by pediatric surgeons. Despite advances in the surgical management, these children may experience symptoms of bowel dysfunction throughout adulthood. Anorectal manometry may be used to assess post-operative anorectal structure and function. This review aimed to consolidate and evaluate the literature pertaining to post-operative findings of anorectal manometry in children with Hirschsprung disease.

PURPOSE

(1) Synthesize the available data regarding anorectal motility patterns in children following repair of Hirschsprung disease. (2) Evaluate the reported anorectal manometry protocols.

DATA SOURCES

We performed a systematic review of four databases: Embase, MEDLINE, the Cochrane Library, and PubMed.

STUDY SELECTION

This systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Studies reporting results of post-operative anorectal manometry in children with Hirschsprung disease were evaluated for inclusion.

RESULTS

Twenty-three studies satisfied inclusion criteria, with a combined cohort of 939 patients. Post-operative anorectal manometry results were reported for 682 children. The majority of included studies were assessed as "poor quality." Disparate manometry protocols, heterogeneous cohorts, and lack of standardized outcome assessments introduced a risk of outcome reporting bias, limited the comparability of results, and impeded clinical translation of findings.

CONCLUSIONS

This systematic review demonstrated the lack of high-quality evidence underlying the current understanding of post-operative anorectal motility in children with HD. There was little consistency in reported manometry outcomes between studies. In future work, emphasis must be placed on the application of standardized manometry protocols, cohort reporting, and patient outcome assessments.

Laparoscopic-assisted Soave procedure for Hirschsprung disease: 10-year experience with 106 cases

Background

The purpose of this study was to summarize the clinical experience and 10 year follow-up results of laparoscopic assisted Soave procedure for the treatment of long-segment Hirschsprung disease (HD).

Methods

From January 2010 to February 2020, 106 children with long-segment HD participated in this study. The laparoscopic-assisted Soave procedure was performed for the treatment of long-segment HD. The follow-up time was two weeks, one month, and three months after the operation, and then every six months to one year.

Results

The operation was successful for all 106 children. All patients were discharged 5–7 days after the operation. The median time in surgery was 150 (100–190) minutes, and the median volume of bleeding was 6 (3–10) ml. The short-term postoperative daily defecation frequency was 4–11 times, 3–7 times within 6 months, and 2–3 times after 6–12 months. Postoperative complications included anastomotic leakage in two cases, perianal dermatitis in 13 cases, anastomotic stenosis in four cases, adhesive bowel obstruction in two cases, enterocolitis in 16 cases, soiling in 11 cases, and constipation recurrence in three cases.

Conclusions

The laparoscopic-assisted Soave procedure is a safe and effective surgical method for treating long-segment HD, and it causes little trauma or bleeding and has a fast postoperative recovery. Yet some complications may occur. Preoperative diagnosis, intraoperative and postoperative standardized processing can reduce the postoperative complications.

Long-term outcomes of single-incision laparoscopic technique in Soave procedure compared with heart-shaped anastomosis for Hirschsprung disease

PURPOSE

This retrospective study compared the long-term outcomes of single-incision laparoscopy-assisted Soave procedure (SILSP) with single-incision laparoscopy-assisted heart-shaped anastomosis (SILHSA) in patients with Hirschsprung disease (HSCR).

METHODS

Patients diagnosed with HSCR that underwent SILSP or SILHSA between January 2009 and January 2015 at our institute were enrolled in this retrospective study. Data on the clinical characteristics, perioperative complications, and postoperative quality of life were retrospectively collected and analyzed.

RESULTS

There were 109 patients in the SILSP group and 95 patients in the SILHSA group. No differences in clinical characteristics, including age, weight, hospitalization length, blood loss volume, and operation time, were noted between the two groups. The incidence rates of constipation and soiling were lower in the SILHSA group than those in the SILSP group. The SILHSA group showed lower scores in constipation and soiling compared with the SILSP group, indicating a better surgical outcome for patients receiving SILHSA procedure.

CONCLUSION

SILHSA is a feasible and reliable minimally invasive surgical procedure for patients with HSCR. Patients who underwent SILHSA had lower incidence rates of constipation and soiling than patients who underwent SILSP, suggesting that SILHSA could be a better choice for patients with HSCR.
