Motility of the oesophagus and small bowel in adults treated for Hirschsprung's disease during early childhood

Comparison of clinical outcomes after total transanal and laparoscopic assisted endorectal pull-through in patients with rectosigmoid Hirschsprung disease

BACKGROUND

Total transanal (TERPT) and laparoscopic endorectal pull-through (LERPT) are the most common procedures to treat rectosigmoid Hirschsprung's disease (HD). Since few studies have compared the two methods, we aimed to assess clinical outcomes after TERPT and LERPT in this cross-sectional study.

METHODS AND PATIENTS

All patients with rectosigmoid HD operated with TERPT and LERPT between 2001 and 2018 were eligible. Peri-operative data were registered from patients' records, and bowel function was assessed according to the Krickenbeck classification.

RESULTS

91/97 (94%) patients were included; 46 operated with TERPT and 45 with LERPT. Bowel function was assessed in 80 patients at median seven (4-17) years. There was no difference in functional outcome between the procedures. Unplanned procedures under general anesthesia were frequent; 28% after TERPT and 49% after LERPT (p = 0.04). 11% of TERPT and 29% of LERPT patients got botulinum toxin injections (p = 0.03). In the TERPT group, patients operated in the neonatal period had poorer outcome (78%) than those operated later (24%) (p = 0.005). No difference in operative time, length of hospital stay, and rate of early and late complications was found between the procedures.

CONCLUSION

There was no difference in long-term bowel function in patients with rectosigmoid HD operated with TERPT or LERPT. More LERPT patients had an unplanned procedure under general anesthesia, mostly due to obstructive symptoms.

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

BACKGROUND

A significant proportion of children experience bowel dysfunction (including constipation and fecal incontinence) following surgical repair of Hirschsprung disease (HD). Persistent symptoms are thought to relate to underlying colonic and/or anorectal dysmotility. Manometry may be used to investigate the gastrointestinal motility patterns of this population.

PURPOSE

To (1) evaluate the colonic manometry equipment and protocols used in the assessment of the post-operative HD population and (2) summarize the available evidence regarding colonic motility patterns in children with HD following surgical repair.

DATA SOURCES

We performed a systematic review of the Cochrane Library, Embase, MEDLINE, and PubMed databases (January 1, 1980 and March 9, 2020). Data were extracted independently by two authors.

STUDY SELECTION

This systematic review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Studies reporting the post-operative assessment of children with HD using colonic manometry were considered for inclusion.

RESULTS

Five studies satisfied selection criteria, providing a combined total of 496 children. Of these, 184 children with repaired HD underwent colonic manometry. Studies assessed heterogeneous populations, utilized variable manometry equipment and protocols, and reported limited baseline symptom characteristics, thus restricting comparability. All studies used low-resolution colonic manometry.

CONCLUSIONS

This systematic review highlighted the paucity of evidence informing the understanding of colonic dysmotility in the post-operative HD cohort. Current literature is limited by variable methodologies, heterogeneous cohorts, and the lack of high-resolution manometry.

Reoperation in an adult female with "right-sided" Hirschsprung's disease complicated by refractory hypertension and cough

Hirschsprung’s disease (HD) is an intestinal malformation caused by the innate absence of ganglion cells in the neural plexus of the colorectal wall, and is most common in male infants. It is rare in adult, and is usually left-sided. Herein we reported based on the CARE guidelines a case of a 47-year-old adult female suffering from “right-sided” HD complicated by refractory hypertension and cough. The patient with a history of cesarean section and with digestive unfitness (abdominal pain, distention, and constipation) only since 20 years old had recurrence of HD after initial surgery due to the incomplete removal of the HD-affected bowel based on a diagnosis of “chronic ileus”, leading to the relapse of the digestive symptoms and the emergence of some intractable circulatory and respiratory complications which could be hardly controlled by conservative treatment. During the long interval before coming to our department for help, she had been re-hospitalized for several times with various misdiagnoses and supplied merely with symptomatic treatment which could only achieve temporary symptomatic relief. At her admission to our department, the imaging examinations strongly indicated recurrent HD which was further supported by pathological examinations, and right hemi-colectomy was performed to remove the remnant aganglionic intestinal segment. Intraoperative and postoperative pathology supported the completeness of the definitive resection. Post-operation, the patient’s bowel motility significantly improved, and interestingly, the complications disappeared. For adult patients with long-term constipation combined with cough and hypertension, rare diseases like HD which requires definite surgery and which could be “right-sided” should not be overlooked. It is vital to diagnose and cure HD patients in childhood. Through the comparison of the two surgeries, it is noteworthy that for diagnosed HD, sufficient removal of the non-functional intestine confirmed by intraoperative pathology is essential.

Anal endosonography and bowel function in patients undergoing different types of endorectal pull-through procedures for Hirschsprung disease

BACKGROUND

The reasons for fecal incontinence after surgery for Hirschsprung disease (HD) remain unclear. The aim of this study was to examine the anal sphincters by anal endosonography and manometry after transanal endorectal pull-through, with or without laparotomy or laparoscopy, in HD patients. Furthermore, we aimed to correlate these findings to bowel function.

PATIENTS AND METHODS

Fifty-two HD patients were followed after endorectal pull-through. Anal endosonography and manometry were performed without sedation at the age of 3 to 16 years.

RESULTS

Endosonographic internal anal sphincter (IAS) defects were found in 24/50 patients, more frequently after transanal than transabdominal procedures (69 vs. 19%, p=0.001). In a multiple variable logistic regression model, operative approach was the only significant predictor for IAS defects. Anal resting pressure (median 40mm Hg, range 15-120) was not correlated to presence of IAS defects. Daily fecal incontinence occurred more often in patients with IAS defects (54 vs. 25%, p=0.03).

CONCLUSIONS

Postoperative IAS defects were frequently detected and were associated with daily fecal incontinence. IAS defects occurred more often after solely transanal procedures. We propose that these surgical approaches are compared in a randomized controlled trial before solely transanal endorectal pull-through is performed as a routine procedure.

Effect of colon transection on spontaneous and meal-induced high-amplitude--propagating contractions in children

BACKGROUND

After Hirschsprung disease (HD) surgery, many children experience fecal incontinence caused by increased number of high-amplitude-propagating contractions (HAPCs) through the neorectum to the anal verge. The aim of this study was to determine whether children with HD have more HAPCs than children with colon transections for reasons other than HD.

METHODS

We reviewed 500 colon manometries. Children (age 7.6 ± 5.1 years, 275 boys) with functional constipation (n = 237, age 7.4 ± 5.0 years, 126 boys) and chronic abdominal pain (n = 48, age 9.8 ± 5.8 years, 25 boys) served as controls compared with subjects with HD (n = 56, age 6.9 ± 4.1 years, 44 boys) and colon transection for other reasons (n = 24, age 6.1 ± 5.8 years, 12 boys). We excluded 139 subjects without HAPCs. We documented HAPCs during 1-hour fasting and 1-hour postprandial. Results are in mean ± SD.

RESULTS

During fasting, HD subjects had more HAPCs (2.2 ± 3.4/hour) versus functional constipation (0.8 ± 2.2/hour, P = 0.0004) and chronic pain (0.5 ± 1.1/hour, P = 0.001), but not more than colon transection (1.9 ± 3.2/hour, P = 1.0). HD showed more postprandial HAPCs (4.0 ± 5.4/hour) than functional constipation (1.5 ± 2.5/hour, P < 0.0001) and chronic pain (0.9 ± 1.6/hour, P < 0.0001), but not more than colon transection (2.4 ± 3.0/hour, P = 0.6). There were more HAPCs fasting and postprandial after colon transection (1.9 ± 3.2/hour and 2.4 ± 3.0/hour) than functional constipation (0.8 ± 2.2/hour, P = 0.3 and 1.5 ± 2.5/hour, P = 1.0) and chronic pain (0.5 ± 1.1/hour, P = 1.0 and 0.9 ± 1.6, P = 1.0). HD subjects were divided by chief complaint: fecal incontinence or constipation. HD subjects with incontinence (n = 23) only had more HAPCs fasting (P = 0.01) and postprandial (P = 0.01) than HD subjects with constipation (n = 28) only.

CONCLUSIONS

Increased HAPCs followed colon transection, regardless of a cause. HD subjects with incontinence had more HAPCs than subjects with colon transection for other reasons.

Esophageal dysmotility is more common than gastroparesis in diabetes mellitus and is associated with retinopathy

OBJECTIVES

Gastroparesis is a well-known complication of diabetes mellitus, both in symptomatic and asymptomatic patients. Esophageal dysmotility has also been described, but is not as well-characterized. The etiology and effect of these complications need to be clarified. The aim of the present study was to evaluate esophageal and gastric motility, complications, gastrointestinal symptoms, and plasma biomarkers in a cross-sectional study comprising patients with diabetes mellitus.

METHODS

Patients with diabetes were consecutively asked to participate, and eventually 84 volunteers were included in the study. Esophageal manometry and the gastric emptying test were performed in all patients. Type of diabetes, symptoms, diabetic complications, body mass index (BMI), and biomarkers were recorded. Patients were interviewed about gastrointestinal symptoms.

RESULTS

Esophageal dysmotility was present in 63% of patients and gastroparesis in 13% of patients. There was no difference in dysmotility between patients with type 1 and type 2 diabetes or between genders. Gastrointestinal symptoms did not correlate to objective findings. Age correlated negatively with gastric emptying rate (p = 0.004). Patients with esophageal dysmotility had longer duration of diabetes compared to those without dysmotility (p = 0.043). In logistic regression analysis, retinopathy was strongly associated with esophageal dysmotility, independent of duration (p = 0.003).

CONCLUSIONS

Esophageal dysmotility is more common than gastroparesis in diabetes mellitus independent of gender, symptoms, and type of diabetes. There is a strong association between retinopathy and esophageal dysmotility.
