Results of rectoanal manometry after a novel laparoscopic technique: laparoscope-assisted heart-shaped anastomosis for Hirschsprung’s disease
The present research utilizes a mid-term follow-up study to assess the results of anorectal manometry after laparoscope-assisted heart-shaped anastomosis (LHSA) for Hirschsprung’s disease (HSCR), and compares it to a more generally applied approach, the laparoscope-assisted Soave procedure (LSP).
Retrospectively, patients from January 2015 to June 2017 who received LHSA or LSP were included in this study. After surgery, anorectal manometry was performed by the outpatient department. Anal sphincter resting pressure, anal canal length, amplitude of anal contraction, and frequency of anal contraction pre- and postoperatively were recorded. Additionally, mid-term complications were also monitored.
Preoperative manometry showed no statistically significant difference between the LHSA and LSP groups. Postoperatively, anal sphincter resting pressure was lower in the LHSA group (60.64 ± 9.33 vs. 68.84 ± 11.80 mmHg, p = 0.001). Furthermore, anal canal length of the LHSA group was shorter than that of the LSP group (1.41 ± 0.18 vs. 1.53 ± 0.25 cm, p = 0.015). Frequency of anal contraction also showed a statistically significant difference between the LHSA and LSP groups (13.53 ± 2.17 vs. 12.50 ± 2.03 per minute, p = 0.032). The complication rates showed no significant difference and were as follows: incidence of enterocolitis was 13.89% in the LHSA group and 20.45% in the LSP group, incidence of constipation was 11.11% after LHSA and 27.27% after LSP, and incidence of soiling was 13.89% after LHSA and 25.00% after LSP.
Manometric results of this study show satisfactory outcomes after LHSA. LHSA is an advanced surgical technique to make intestinal anastomosis easy and ensure a good prognosis.
