Redo surgery with longitudinal resection for dilated bowel in Hirschsprung disease: an illustrative case series
- 191 Downloads
Patients with Hirschsprung disease (HD) can have persistent obstructive symptoms after resection of the aganglionic segment. If obstructive symptoms are treated inadequately, this may lead to recurrent faecal stasis and impaction, and may result in severe distension of the bowel. A permanently distended bowel which not responds to conservative treatment may be an indication for redo surgery. The aim of this study is to describe our experiences and the short-term results of a novel technique: longitudinal antimesenteric resection with a longitudinal anastomosis.
We reviewed the medical records of our three patients who underwent longitudinal resection of severe distended bowel. This technique aims to improve defecation by improving faecal passage and is characterized by resection of the antimesenteric side of the distended intestinal segment, followed by plication with a longitudinal anastomosis. In this paper, this novel technique is described in detail, as well as short-term outcomes.
All patients had an uneventful recovery after longitudinal antimesenteric resection. During follow-up, the functional outcomes were excellent, with a large improvement of bowel function. All patients were continent for faeces, and treated with low-dose laxatives or occasional preventive irrigation in one patient. There were no more complaints of persistent constipation or soiling.
Longitudinal resection is a surgical redo-procedure offering large benefits for patients with Hirschsprung disease with distended bowel after primary surgery.

Hirschsprung disease (HD) is a congenital motility disorder characterized by aganglionosis of the distal colon, for which surgery to resect aganglionic bowel is necessary. Thirty to 50% of patients experience defecation problems after primary surgical treatment [1, 2], of which persistent obstructive problems such as constipation are the most common. Possible causes for persistent obstructive complaints include anastomotic stricture, residual aganglionosis, mechanical obstruction due to adhesions, sphincter problems and stool holding behaviour . Persistent obstructive defecation problems are primarily treated with conservative measures, including laxatives, rectal irrigation, intrasphincteric botulinum toxin injections or anal dilatation . If obstructive symptoms are treated inadequately, this may lead to recurrent faecal stasis and impaction resulting in progressing and permanent distension of the bowel. Severe bowel distension negatively affects bowel motility, thereby aggravating faecal stasis and increasing the risk of developing Hirschsprung-associated enterocolitis (HAEC), which can be life-threatening [4, 5]. In these patients with persistent obstructive symptoms and permanently dilated bowel, redo surgery may be indicated . Most often a redo pull-through is performed in order to surgically remove the distended non-motile bowel and restore faecal passage. However, redo surgery is complex and associated with relatively high rates of soiling or faecal incontinence and enterocolitis [7, 8, 9].
In this paper, we present a case series of three patients successfully treated with an alternative technique for redo surgery in patients with extremely dilated non-motile bowel: resection of the antimesenteric side of the dilated non-motile bowel segment, followed by plication with a longitudinal anastomosis.
The medical records of three patients who underwent longitudinal resection and plication were retrospectively reviewed. Data on (1) demographic characteristics of patients (i.e. sex, age at primary pull-through, age at longitudinal resection), (2) disease characteristics and clinical course (i.e. length of the initial affected and resected segment, previous interventions), (3) the procedure of longitudinal resection (i.e. what bowel segment was treated with longitudinal resection, how long this segment was, whether an open or laparoscopic procedure was performed, what type of suturing was used, whether the operation was performed under the protection of an ostomy) and (4) clinical course after longitudinal resection (i.e. occurrence of complications, occurrence of obstructive symptoms, use of laxatives or rectal irrigation, faecal continence and length of follow-up) was extracted from the medical records. Based on this data, a summary of our experiences with the clinical course of these patients before redo surgery, description of the operation technique and a summary of experiences with the clinical recovery of these patients were provided in this paper.

Description of the procedure
Clinical outcomes in follow-up
Our study shows excellent short to medium term results after longitudinal resection in patients who developed distended bowel and obstructive symptoms after primary surgery because of Hirschsprung disease, with good clinical recovery. This indicates that longitudinal antimesenteric resection might be a safe and effective alternative treatment strategy for Hirschsprung patients with extremely dilated bowel because of persistent obstructive defecation problems after a pull through.
There is currently no consensus on the best surgical procedure for this group of patients [7, 10, 11, 12, 13]. Frequently used techniques for secondary surgery include resection of the dilated segment with or without a redo pull-through, myotomy of the sphincter or a permanent colostomy. Disadvantages of re-resection of the dilated segment without a redo pull-through are further omission of bowel length and vascular supply, as well as jeopardizing the distal segment if the original distal anastomosis remains in place. Simultaneous resection of the distal segment as well carries higher risk of future defecation disorders, especially faecal incontinence . Disadvantage of a permanent colostomy is the time-consuming daily care, as well as the risk of stoma-related complications such as skin problems, prolapse and parastomal herniation . A longitudinal resection leads to recovery of normal bowel diameter, thus decreasing bowel wall tension and increasing intraluminal pressure, thereby improving peristalsis and passage of faeces through the bowel. Moreover, this technique offers the benefit of preservation of larger sections of the colon and thus its resorbing function, as well as sustaining optimal vascularization of the gut. This is important as both damage of the vascular arcade and interruption of intramural blood supply may result in bowel necrosis or fibrosis with possible devastating consequences for continence later in life. In this small series, we had no complications of longitudinal antimesenteric resection.
Despite the good results in terms of bowel diameter and clinical improvement in our patients, we still have limited experience with longitudinal antimesenteric resection. This technique is suitable for patients with a permanent severely dilated colon, without any signs of residual aganglionosis or an anastomotic stricture as cause of obstruction. Therefore, this treatment option can only be applied for a small and specific subgroup of patients with HD and obstructive symptoms. We have described our experience with longitudinal resection in three patients, but in the future, more and longer experience with this technique is necessary, to assess if the good results can be confirmed and which patients would benefit most of this technique.
In conclusion, longitudinal antimesenteric resection is a surgical procedure offering multiple benefits for patients with HD with obstructive complaints and distended bowel for whom redo surgery is indicated: the preservation of bowel and vascularization. In this case series, clinical outcomes were good, but further research on outcomes in long-term follow-up and possible complications is necessary before clinical implications can be recommended.
