Intra-operative pathological diagnosis of chronic ulcerative colitis in the two stage ileal pouch anal anastomosis

[Differential indications for ileoanal pouch anastomosis : Ulcerative colitis, familial adenomatous polyposis, synchronous colorectal cancer - Crohn's disease, constipation]

Ileoanal pouch anastomosis is the procedure of choice for patients with drug refractory ulcerative colitis, indeterminate colitis and familial adenomatous polyposis (FAP). In selected patient groups this procedure is a treatment option for patients with Crohn's disease, hereditary nonpolyposis colorectal cancer (HNPCC), synchronous colorectal cancer and for severe colorectal constipation refractory to conservative drug treatment. The pouch procedure provides the opportunity to avoid a permanent ileostomy. The majority of surgeons prefer the ileal J‑pouch as the construction is the easiest to perform and complications and dysfunction rates are low. Due to functional reasons most pouch surgeons favor a circular stapled ileoanal pouch anastomosis. The more radical proctocolectomy can produce sensory defects in the anal canal with subsequent soiling and incontinence. Studies have shown that even after proctocolectomy residual rectal mucosa was found in the anal canal. Therefore, the functionally important anorectal transitional zone should be preserved if possible. Ulcerative colitis can be "healed" with proctocolectomy; however, pouchitis can still occur in one third of the patients. Patients must be informed about the risk of pouchitis and a multidisciplinary monitoring and treatment strategy must be available. In Crohn's disease the ileoanal pouch survival rate of 80% in the long-term follow-up is surprisingly good despite an increased postoperative complication rate. The anal pouch anastomosis is the standard operation in patients with drug refractory ulcerative colitis, indeterminate colitis and FAP. Synchronous colorectal cancer, HNPCC and severe therapy refractive constipation represent rare indications for proctocolectomy where decisions must be made on an individual basis.

National trends of 3- versus 2-stage restorative proctocolectomy for chronic ulcerative colitis

BACKGROUND

Patients undergoing surgical treatment of chronic ulcerative colitis usually undergo a staged approach to IPAA.

OBJECTIVE

The purpose of this work was to identify the national trends in approach to IPAA for chronic ulcerative colitis and to evaluate 30-day outcomes using the American College of Surgeons National Surgical Quality Improvement Program.

DESIGN

This was a retrospective review study

SETTINGS

: This study was conducted at a tertiary care cancer center.

PATIENTS

Patients with chronic ulcerative colitis who underwent IPAA from 2005 to 2011 were identified. Those who underwent colectomy with pouch procedure were placed in a 2-stage cohort, and those without simultaneous colectomy were part of a 3-stage cohort. Emergent operations were excluded.

MAIN OUTCOME MEASURES

Trends in procedure mix, preoperative characteristics, and postoperative 30-day outcomes were compared. Multivariate analysis was used to identify independent risk factors for postoperative infection.

RESULTS

Of 2002 patients who underwent IPAA, 1452 (72.5%) underwent 2-stage and 550 (27.5%) underwent 3-stage surgery. Since 2007, the distribution of 2- versus 3-stage procedures has not changed (p = 0.66). At the time of pouch surgery, patients who had undergone 3-stage surgery were less likely to have preoperative corticosteroid therapy, albumin <3 mg/dL, preoperative sepsis, and weight loss (all p < 0.05). Superficial surgical site infection was more common after 3-stage surgery (11.5% vs 7.3%; p < 0.01). After controlling for preoperative factors, wound classification was the only independent predictor of deep incisional or organ space infection (p < 0.01; OR, 1.76; 95% CI, 1.23-2.53).

LIMITATIONS

This was a retrospective study.

CONCLUSIONS

National trends of 2- versus 3-stage IPAA have remained stable over the last 5 years. Patients who underwent a 3-stage approach were healthier at the time of pouch surgery, with decreased corticosteroid use, hypoalbuminemia, and weight loss. Mixed results were seen for infectious complications with either approach. Prospective research is needed to determine the best approach to IPAA for chronic ulcerative colitis.

Review article: restorative proctocolectomy, indications, management of complications and follow-up--a guide for gastroenterologists

BACKGROUND

Restorative proctocolectomy with ileal pouch-anal anastomosis is the procedure of choice for the majority of patients with ulcerative colitis who require surgery. Over 2500 patients in the UK have undergone restorative proctocolectomy. It is now increasingly being performed in district general hospitals as well as in specialist inflammatory bowel disease units. Gastroenterologists are increasingly involved in the management of patients following restorative proctocolectomy.

AIM

To provide gastroenterologists with a clear understanding of the investigation and evidence-based management of complications and the aftercare required in patients who have undergone restorative proctocolectomy.

RESULTS

Following restorative proctocolectomy, most patients have an excellent long-term functional outcome. Pouchitis, pelvic sepsis and poor function are the most common causes of failure. The development of cancer is rare; nevertheless, long-term follow-up is required.

CONCLUSIONS

The investigation and management of patients who develop complications require a multidisciplinary team approach to optimize the outcome. Protocols are suggested for investigation and management of patients with complications and for long-term cancer surveillance.
