Hirschsprung disease with debut in adult age as acute intestinal obstruction: Department of General and Gastrointestinal Surgery. Hospital Universitario Virgen Macarena.
Hirschsprung’s disease is characterized by absence of ganglion cells in submucosal and myenteric plexus of distal bowel. Most cases become manifest during the neonatal period, but in rare instances, this disease is initially diagnosed in adult age. It usually presents as severe constipation with colonic dilatation proximal to the aduotos segment.
The treatment is surgical, removing the aganglionic segment and restoring continuity of digestive tract. The disease rarely presents as an acute intestinal obstruction. We report a case not previously diagnosed, which presented as a massive colonic dilatation with a maximum diameter of 44 cm, with imminent risk of drilling that forced to perform an emergency surgery.
We include a review of existing literature. Suele diagnosticarse en el periodo neonatal, siendo muy poco frecuente que se descubra en el adulto. Hirschsprung’s disease HD is a malformation of the large intestine characterized by the absence of ganglion cells in submucosal and myenteric plexus, which produces a functional obstruction and dilatation proximal to the affected segment 1.
This congenital disease is usually detected in neonatal period. It is rarely diagnosed in adult age. Approximately cases have been reported in literature. These patients tend to have milder forms of the disease, in which hypertrophy of innervated proximal colon compensates the functional obstruction by lack of innervation of the distal area 2. We report a case of a year-old male patient that was admitted in the Emergency Department because of a massive megacolon that required a total colectomy with ileum-rectal anastomosis.
enfermedas A year-old male was admitted in the Emergency Department by generalized abdominal enfermedar accompanied by anorexia of several days duration. Previous history of meningioma operated inintestinal resection in childhood unknown etiologychronic constipation, smoker of 20 cigarettes per day and moderate drinker. The patient reported difficulty for expelling gases, although he expelled stools without pathological products.
No nausea or vomiting. Abdomen was very distended and tympanic, with previous laparotomy scar, painful on palpation diffusely. Peritoneal irritation was not found. Abdominal X-rays showed a dilated enfermedsd occupying abdominal cavity. Laboratory studies revealed leukocytosis with left deviation and elevated C-reactive protein. A CT scan was performed, showing a massive dilatation of sigmoid colon, which compresses liver to the hirschspeung upper quadrant, stomach hirschsprunf the left upper quadrant and bowel loops into the right flank Figs.
A transition zone was appreciated in distal sigmoid colon. Rectum had a normal size. Peripheral aerial imagery was found in the dilated segment, gas-like wall, which is thickened in this segment. Given these findings, emergency surgery was decided.
A midline laparotomy was performed, finding a massive dilatation of sigmoid colon, attaining a diameter fnfermedad 44 cm at its more dilated portion. The adultls of the colon was also dilated. Rectum had normal caliber.
It was decided to perform a total colectomy with ileum-rectal anastomosis. After 24 hours, the patient presented hemodynamic instability, with severe abdominal pain. CT scan was performed, showing signs of peritonitis caused by dehiscence of ileum-rectal suture. Emergency surgery was indicated, performing an anastomosis resection and end ileostomy. Postoperative evolution was torpid, with difficulty feedback by adynamic ileus and infection of surgical wound.
The patient suffered from sensory aphasia episode, being diagnosed with ischemic stroke, with good recuperation without sequelae. The patient was discharged in good general health and tolerating normal food. The pathologist’s report showed the existence of ulceration foci with acute inflammation in the submucosa.
Observing the Meissner and Auerbach plexus with immunohistochemical techniques and enolase S, loss of neurons ganglion cells and lower density of such plexuses were observed with respect to a normal colon Figs. There was neuronal dysplasia with scarce presence of ganglion cells on both edges of resection.
Pathological diagnosis was Hirschsprung disease. Hirschsprung’s disease affects about 1 in 5, live births and usually presents in neonatal period. Only a small number of cases remain undiagnosed after 5 years of age 2. Only cases of HD have been described in adults, with male hirschhsprung in enfermddad 4: The age of patients ranges from 10 to 73 years old.
Fifty per cent of the patients are younger than 30 years of age 3.
Nowadays its incidence in adult is unknown as this diagnosis is often overlooked in adult ebfermedad 4. The primary defect is absence of ganglion cells in Meiss-ner plexus submucosal and Auerbach plexus myenteric in the affected segment of large bowel. This is the result of a lack of migration of neuroblasts from the neural crest to the large intestine during embryonic period.
Other proposed mechanisms include defects in the neuroblast differentiation and accelerated destruction of ganglion cells in the intestine 4. Aganglionic segment remains permanently contracted, while proximal segment retains peristalsis, enfemedad in hypertrophy, megacolon and sometimes perforation of normally innervated segment 2.
Fecal incontinence is not typical in adults, unlike children. The diagnosis of HD in adults is much harder than in hirschprung, due to their rarity as they are often short or ultrashort aganglionic segments, which produce mild symptoms in early stages of the disease.
Plain films typically show a massive expansion of proximal colon, with a small distal segment. A CT scan is a useful tool, not only to show the transition zone, but to exclude other causes of chronic constipation and megacolon in adults, such as colorectal cancer, volvulus, stricture, slowing of colonic re, Chagas disease, anatomical or functional obstruction to defecation or idiopathic megacolon 2.
The diagnosis is made by barium enema, anorectal manometry and rectal biopsy.

The key finding in barium enema is the existence of a transition zone “funnel” between distal aduotos bowel normal or narrow and proximal dilated.
Not displaying this transition zone does not exclude the diagnosis of HD. Anorectal manometry shows lack of relaxation of internal anal sphincter in response to rectal distension. The rectal biopsy should be made on the back side of rectum, about 6 cm height, dnfermedad it shows absence hirsfhsprung ganglion cells, nerve fibers hyperplasia and an increased level of acetylcholinesterase 7. The treatment is surgical, in order to remove the aganglionic segment and restore digestive continuity.
The surgical approach will depend on length of aganglionic area, length and reversibility of colonic dilatation, and nutritional status of patient. In our case, we are in a situation of irreversible dilatation of entire colon, so we opted for a total colectomy, restoring intestinal transit by ileo-rectal anastomosis.
Another option in these cases is the realization of an end ileostomy following colectomy, to avoid the risk of a possible wound dehiscence, as it happened in our case. The disadvantage of this technique is that it requires sdultos new intervention to restore the intestinal transit.
The choice of either technique will depend on general condition of patient and abdominal conditions existence of enfemedad, peritonitis, etc. Several procedures have been designed to treat HD, of which the most important are the following 7: The aganglionic segment is sectioned into the abdomen. This segment is everted and extracted by transanal way. Then we proceed to perform a resection and anastomosis between healthy colon and anal enfermeda.
In this case, the aganglionic segment is not removed, but a rear dissection is performed. The healthy colon is descended from behind of the aganglionic segment, performing the anastomosis between the two segments Fig. With this technique an extensive dissection of the anterior wall of the rectum is avoided, thus avoiding the risk of injuring adjacent structures.
A resection of distal rectal mucosa of the aganglionic segment is performed, maintaining muscular wall of this segment. Then, normal colon is lowered through the aganglionic segment, making an anastomosis at level of Morgagni columns.
It consists in a rear section of muscular wall of rectum starting from dentate line by transanal waywhich removes some of the top segment of internal anal sphincter, getting relief stenosis.
Given the low incidence of Adultow in adults, it is difficult to compare different procedures.

In recent years, the Duhamel technique has been considered as the best option. Compared with the Soave and Swenson procedures, it is superior in terms of impotence rate, anastomotic dehiscence and reservoir function to minimize soiling 8. Myomectomy has the advantage of being technically easier and presenting a low morbidity, but it has worse functional outcomes and can only be used in ultra-HD 7,8. We can conclude that HD is a rare entity in adults and should be suspected in patients with megacolon with a history of constipation refractory to treatment since childhood.
As in our case, it may rarely occur as massive colonic dilatation with risk of perforation, which requires emergency surgery.
