Accuracy of transition zone in contrast enema to predict intraoperative aganglionosis level in patients with Hirschsprung disease.

ABSTRACT: OBJECTIVE:While frozen section methods have been widely conducted to determine aganglionosis segment during transanal endorectal pull-through (TEPT) for Hirschsprung disease (HSCR) patients in most institutions, some hospitals still rely on contrast enema to predict aganglionosis segments due to unavailability of frozen section facilities. We determined the accuracy of transition zone in contrast enema to predict aganglionosis segments during TEPT. We retrospectively reviewed all contrast enema and frozen sections for HSCR patients under 2 years of age who underwent TEPT at our institution. RESULTS:We recruited 36 HSCR patients: twenty-six patients (72.2%) had radiographic transition zones limited to rectum, while ten subjects (27.8%) were limited to rectosigmoid. The rectum subgroup of patients showed a concordance of 30.8%, whereas the rectosigmoid subgroup had a concordance of 100%. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of contrast enema compared with intraoperative histopathological findings for aganglionosis level were 100% (95% CI 0.60-1.0), 35.7% (95% CI 0.19-0.56), 30.8% (95% CI 0.15-0.52), 100% (95% CI 0.66-1.0), and 50% (95% CI 0.33-0.67), respectively. In conclusions, contrast enema has low accuracy to predict intraoperative aganglionosis segments in HSCR patients, indicating that it might not be utilized to determine aganglionosis level during TEPT.

Project description:Objective: The aim of this study was to describe the details of laparoscopic-assisted reoperative surgery for Hirschsprung's disease (HSCR) with overflow fecal incontinence, and to retrospectively compare laparoscopic-assisted surgery with transabdominal pull-through surgery. Methods: We retrospectively analyzed patients with HSCR with overflow fecal incontinence after the initial surgery in our center between January 2002 and December 2018. Pre-operative, peri-operative, and post-operative data were recorded for statistical analysis. Results: Thirty patients with overflow fecal incontinence after initial megacolon surgery [17 who underwent transanal pull-through (TA-PT) and 13 who underwent laparoscopic-assisted pull-through (LA-PT)] required a secondary surgery [reoperation with LA-PT (LAR-PT) (n = 16) or reoperation with transabdominal pull-through (TR-PT) (n = 14)]. Indications for reoperation were residual aganglionosis (RA) (7/30, 23.3%) or transition zone pathology (TZP) (23/17, 76.7%). Blood loss was significantly decreased in the LAR-PT group (75 ± 29.2 ml) compared to the TR-PT group (190 ± 51.4 ml) (P = 0.001). The length of hospital stay was significantly shorter in the LAR-PT group (10 ± 1.5 days) than that in the TR-PT group (13 ± 2.4 days). No significant differences were found between two groups in surgical methods, defecation function score, or post-operative complications except for wound infection (LAR-PT vs. TR-PT 0 vs. 28.6%, P < 0.05). Conclusions: It is necessary to make a comprehensive analysis of the causes of fecal incontinence after HSCR surgery and make an accurate judgment using appropriate methods. If a reoperation was inevitable for patients with overflow fecal incontinence due to RA or TZP, a comprehensive evaluation prior to the operation is required to maximize the benefit from reoperation. Although laparoscopic reoperation with heart-shaped anastomosis was safe and feasible for patients with failed initial Soave technique, unnecessary reoperation should be avoided as much as possible.
