Over a 16-year period 34 patients underwent surgery for idiopathic megarectum or megacolon; 18 had megarectum with or without megasigmoid, one megacolon only and 15 megarectum and total megacolon (nine with a previous colectomy). Ten patients underwent low rectal or anal anastomosis without pouch formation (colodistal proctostomy, eight; coloanal anastomosis, two), eight had colonic pouch-anal anastomosis (J pouch) and 14 had an ileal J pouch after restorative proctocolectomy; one underwent subtotal colectomy with ileorectal anastomosis and one loop ileostomy alone. There was one death, from intestinal obstruction 24 months after operation. Twenty-seven of 32 evaluable patients without a stoma became fully continent following resection and sphincter-saving procedures. Three of 18 had a poor result after resection for megarectum because of recurrent constipation. One of 14 patients became incontinent after restorative proctocolectomy for megacolon and megarectum and in a further four persistent abdominal distension and pain was treated by pouch excision.

Patients with intractable chronic constipation should be evaluated with physiologic tests after structural disorders and extracolonic causes have been excluded. Conservative treatment options should be tried excessively. If surgery is indicated subtotal colectomy with IRA is the treatment method of choice. However, segmental resection may be a good option for isolated megasigmoid, sigmoidocele or recurrent sigmoid volvulus. In general patients with GID should not be offered any surgical options because of their anticipated poor results. Moreover, patients with psychiatric disorders should be actively discouraged from resection as they tend to have poorer prognosis. Patients must be counseled that preoperative pain and/or bloating will likely persist even if surgery normalizes bowel frequency. Patients with associated problems may be better served by having a stoma without resection as both a therapeutic maneuver and a diagnostic trial. Colectomy is no option to treat pain and/or abdominal bloating.

Patients with intractable chronic constipation should be evaluated with physiological tests after structural disorders and extracolonic causes have been excluded. Conservative treatment options should be tried unstintingly. It should be pointed out that especially new drugs such as prucalopride and linaclotide seem to be a big step forward in treating patients with chronic constipation. If surgery is indicated, for many years subtotal colectomy with IRA was the treatment of choice, although segmental resections were also a good option for isolated megasigmoid, sigmoidocele or recurrent sigmoid volvulus. Nowadays, less invasive procedures like sacral nerve modulation (SNM) should be tried first. If unsuccessful, colectomy can still be considered. In general, patients with a gastrointestinal dysmotility syndrome (GID) should not be offered any surgical options because of their anticipated poor results. Moreover, patients with psychiatric disorders should be actively discouraged from resection, as they tend to have a poorer prognosis. Patients must be counseled that pain and/or bloating will likely persist even if surgery normalizes bowel frequency. Patients with associated problems may be better served by having a stoma without resection as both a therapeutic maneuver and a diagnostic trial. Colectomy is not an option for the treatment of pain and/or abdominal bloating. In most cases outlet obstruction can be treated successfully with a conservative approach. However, nowadays there are also a variety of surgical options on the market. Each technique has its special place in the armamentarium of a colorectal surgeon but its exact role is not defined yet.The aim of this article is to give a brief overview, how to diagnose and treat chronic constipation from the standpoint of a colorectal surgeon.Surgical treatment of chronic constipation is not routine and is performed only in exceptional cases. But one thing first: a "too long gut" (dolichocolon) per se is never an indication for surgery. The aim of this manuscript is to give a brief overview about possible mechanisms of constipation, diagnostic methods and tools and the various conservative and operative treatment options. Moreover, please always keep in mind that constipation may not only be a symptom, but even a distinct disease!
