MRI assessment of the bony pelvis may help predict resectability of rectal cancer.

OBJECTIVE: The outcome after surgical treatment of rectal cancer may be influenced by the technical difficulty of the operation, which is thought to be affected by pelvic size. The aim of this study was to examine the association between bony pelvic dimensions and CRM involvement. PATIENTS AND METHODS: All patients with primary rectal cancer between December 1999 and January 2002 were studied. Staging was performed by pelvic MRI. Nine pelvic dimensions were measured from the MR images on a workstation. Pathology reports were obtained for all patients and the mesorectal specimen was examined. Technical difficulty was assessed by circumferential resection margin (CRM) involvement. RESULTS: Of 126 patients with primary rectal cancer, 88 had staging MRI and rectal excision; there were significant differences between the sexes in all 9 pelvic dimensions (P < 0.05). In females, the interspinous diameter was significantly shorter in patients with CRM involvement compared with patients with a negative CRM. In female patients predicted to have a negative CRM, the anteroposterior diameter of the inlet, the anteroposterior diameter of the midplane and the transverse diameter of the midplane (interspinous distance) were significantly shorter in patients who actually had a positive CRM compared with those in whom the CRM was negative. In male patients, there was no correlation between pelvic dimensions and CRM status. CONCLUSIONS: In certain patients with rectal cancer, CRM positivity may be predicted from pre-operative MRI pelvic measurements. This may influence the choice of adjuvant therapy.

Long-term outcome of per anum intersphincteric rectal dissection with direct coloanal anastomosis for lower rectal cancer.

OBJECTIVE: The authors have performed per anum intersphincteric rectal dissection. With direct coloanal anastomosis for cases of lower rectal cancer in which the distal surgical margin is difficult to secure by the double stapling technique. The aim of this study was to evaluate the long-term outcome and to clarify the surgical indications for this operation. PATIENTS AND METHODS: Between 1993 and 2002, 31 patients underwent per anum intersphincteric rectal dissection with direct coloanal anastomosis. Of these, two patients (one stage 0 and one stage IV) were excluded from the analysis of oncological outcome. The remaining 29 patients formed the basis of this study. The median follow-up was 57 months (range 6-106 months). RESULTS: Local recurrence and distant metastasis developed in 9 and 3 patients, respectively. Local recurrence rate for pT1 was significantly lower than that for pT2/T3 disease. The local recurrence rate cases with tumours less than 3 cm was significantly lower than that for tumours sized 3 cm or more. The distant metastasis rate for cases with lymph node metastasis was significantly higher than that for cases without lymph node metastasis. There was an association between distant metastasis and TNM or pT stage. The overall survival rates for stage I, II and III were 85%, 80% and 89%, respectively. No significant difference was seen in total Cleveland Clinic incontinence score between per anum intersphincteric rectal dissection with direct coloanal anastomosis and the double stapling technique. CONCLUSION: The surgical indications of this operation should be limited to patients with T1 rectal cancer or tumours less than 3 cm.

Ileal pouch anal anastomosis for ulcerative colitis is feasible for septuagenarians.

OBJECTIVE: Proctocolectomy and ileal pouch anal anastomosis (IPAA) has become the standard surgery for patients with mucosal ulcerative colitis (MUC). Although there is no absolute age limitation, there are concerns as to its use in elderly patients due to the risks of potential complications and poor function. The aim of this study was to assess the complications and outcome of patients over the age of 70 years with MUC who underwent IPAA. Results in these patients were compared to the results in a group of patients aged less than 70 years who had IPAA. METHODS: After Institutional Review Board approval, a retrospective review of the medical records of patients with MUC who underwent IPAA was undertaken. These patients were divided into four age groups: <30 years of age, 30-49 years, 50-69 years, >or=70 years. RESULTS: From 1989 to 2001, 330 patients underwent IPAA for preoperative clinical and histopathological and postoperative histopathologically confirmed MUC; 17 were aged>or=70 years. The mean hospital stay was 5.8 (SEM 0.7) days in the patients aged<70 years and 6.0 (SEM 0.4) days in the patients aged>or=70 years (P=0.911). Postoperative complications occurred in 39% of patients>or=70 years and in 40% in the <70 years group (P=0.08). Pouch failure occurred in two (11.8%) patients>or=70 years and in 6 (1.9%)<70 (P=0.2). CONCLUSION: IPAA is a safe and feasible option in MUC patients over the age of 70 with functional results similar to results seen in younger patients.

Ileal pouch-anal anastomosis: the Australasian experience.

OBJECTIVE: The aim of this project was to establish and maintain an internet-based database of all ileal pouch procedures performed in major centres in Australasia. METHOD: The initial three colorectal units contributing data are Auckland, northern Brisbane and Central Sydney Area Health Service. A web-based database was designed. The data collection method was tested on a subgroup of 20 patients to ensure functionality. Data were collected in five main categories: patient demographics, preoperative data, operative details, postoperative complications and functional results. RESULTS: Initial data are presented for 516 patients [363 J, (70%), 133 W (26%), 16 S pouches (3%)]. There were two deaths within 30 days (0.4%). The anastomotic leak rate overall, in handsewn (HSA) and stapled anastomoses (SA) respectively was 5.0%, 8.5% and 3.3% (P=0.02 for difference HSA vs SA). Incidence of pouchitis was 20% (ulcerative colitis 23%, Crohn's disease 20%, indeterminate colitis 22%, familial adenomatous polyposis 9%). Incidence of anal stricture requiring intervention (11% overall) was significantly greater in HSAs than in SAs (16%vs 9%, P=0.02). Incidence of small bowel obstruction at any time postoperatively was 16%. Functional data were available for 234 patients. The median frequency of bowel actions during waking hours was significantly less in W pouches than in J pouches (four vs five, P=0.0005). CONCLUSION: A national web-based database has been developed for access by all Australasian colorectal units. Initial Australasian data compare favourably with other international studies. Pouchitis continues to be a long-term problem. The leak rate and rate of late anal stricture requiring a procedure are higher if the anastomosis is handsewn rather than stapled. Functional results are better with the W pouch than with the J pouch.

Histopathological changes in Kock pouch.

To investigate whether tumour recurrence or histological changes occur in the Kock pouch, periodic endoscopy with biopsy of the pouch was performed in 15 patients 6 to 66 months after radical cystectomy and urinary diversion for invasive bladder cancer. Endoscopy was undertaken 1 to 4 times in each patient (a total of 37 times in all patients). During endoscopy, random biopsies were taken from the pouch wall, and from the afferent and the efferent nipples. The histological changes were graded as: (1) villous atrophy (grade 0 to 3, 0: nearly normal; 1: shortening, villi/crypt of Lieberkuhn [length] between 1.5 and 4.0; 2: moderate flattening, villi/crypt < 1.5; and 3: almost complete disappearance of villi); (2) fibrosis; and (3) chronic inflammation (grade 0 to 3, based on the amount of fibrous tissue and inflammatory cell infiltration in the lamina propria, respectively). There was no dysplasia or malignant tumour in the Kock pouch in any of the 15 patients. The histology of the ileum changed in terms of villous atrophy, fibrosis and chronic inflammation in the lamina propria and thickening of the muscularis mucosa. The same grade of villous atrophy of the pouch wall, the afferent and the efferent nipples was only found in 3 patients. More fibrosis and less chronic inflammation in the lamina propria were found at the efferent nipple than at the afferent nipple or pouch wall in 8 patients and 5 patients, respectively. Thickening of the muscularis mucosa was found in 13 of 15 patients (86.7%). In conclusion, there was no dysplasia or recurrent tumour in the Kock pouch in patients who were followed for up to 66 months. Various grades of histological changes of the ileum in terms of villous atrophy, fibrosis and chronic inflammation of the lamina propria, and thickening of the muscularis mucosa were found in the pouch wall, and in the afferent and efferent nipples. More fibrosis and less chronic inflammation were commonly observed at the efferent nipple than at the afferent nipple or pouch wall. The degree of histological changes varied even among patients followed over the same period after operation. The time to progression of villous atrophy also varied. The histological changes in some patients were dissimilar even at the same site of the Kock pouch.

Pelvic exenteration without external urinary or fecal diversion in gynecological cancer patients.

In 1993, the authors introduced an orthotopic bladder replacement technique in the treatment of gynecological cancer patients. In this series, they report their long-term experience with orthotopic urinary reconstruction in case of primary- and radiotherapy-treated recurrent gynecological malignancies. Between 1993 and 2003, in 29 patients orthotopic ileocecal ascending colon reservoirs (Budapest pouch) were created. Twenty-one of the 29 patients received radiotherapy prior to their operation. In 12 out of these 29 cases, the fecal stream was reconstructed with the use of low rectal anastomosis. Two patients (6.9%) died in the perioperative period. Orthotopic reconstruction of the lower urinary system was successful in 77% of the cases. Success rate was 68% in the irradiated cohort of patients. All orthotopic bladder replacement patients voided voluntarily at the time of their follow-up, without the need of self-catheterization, and 23.5% of them complained of some degree of daytime incontinence and 47% of nighttime incontinence. Low rectal anastomosis reconstruction of the fecal stream was successful in all but one case. Our present experience demonstrated that anterior and total supralevator pelvic exenteration in patients with gynecological malignancies is feasible with orthotopic reconstruction of the lower urinary tract.

Factors related to the presence of IgA class antineutrophil cytoplasmic antibodies in ulcerative colitis.

OBJECTIVES: Few studies have assessed the IgA antineutrophil cytoplasmic antibody (ANCA) positivity in ulcerative colitis patients and there is no information about factors related to its synthesis and its status after colectomy. The aims of the study were to assess the serum IgA ANCA prevalence in ulcerative colitis patients, both nonoperated and operated, and to determine the clinical factors related to this positivity. METHODS: Fifty-four ulcerative colitis patients, 63 ulcerative colitis colectomized patients (32 with Brooke's ileostomy and 31 with ileal pouch anal anastomosis), and 24 controls were studied. Antineutrophil cytoplasmic antibodies were detected by specific indirect immunofluorescent assays. RESULTS: The percentage of IgA ANCA was significantly higher in patients with ileal pouch anal anastomosis (45%) than in patients with Brooke's ileostomy (22%). There were no differences related to the presence of pouchitis in ileal pouch anal anastomosis patients. Patients with nonoperated extensive colitis (47%) had a significantly higher percentage of IgA ANCA than patients with proctitis (19%). Total percentage of ANCA (IgA and/or IgG) tended to be higher in ulcerative colitis and in patients with ileal pouch anal anastomosis than in patients with Brooke's ileostomy. However, in ileal pouch anal anastomosis patients, ANCA positivity was mainly due to exclusive IgA production. CONCLUSIONS: A substantial percentage of ulcerative colitis patients, and especially colectomized patients with ileal pouch anal anastomosis, had IgA ANCA, suggesting that ANCA production in ulcerative colitis might be stimulated by an immune reaction in the intestinal mucosa.

A prospective evaluation of health-related quality of life after ileal pouch anal anastomosis for ulcerative colitis.

OBJECTIVES: The ileal pouch anal anastomosis is a safe and effective procedure but is also associated with pouchitis, small bowel obstruction, and incontinence. We prospectively evaluated the health-related quality of life using generic and disease-specific measures in a cohort of patients with ulcerative colitis undergoing ileal pouch anal anastomosis. METHODS: Health-related quality of life measures included the Time Trade-off, Rating Form of IBD Patient Concerns, and the Short-Form 36. Assessments occurred preoperatively and 1, 6, and 12 months postoperatively. RESULTS: Time Trade-off scores had significantly improved at the 1-month postoperative assessment and approached perfect health at the 12-month postoperative assessment. The Rating Form of IBD Patient Concerns revealed a significant reduction in patient concerns at 1 month, and this difference persisted at 6 and 12 months. Seven of the eight subscales of the Short-Form 36 revealed improved health-related quality of life postoperatively. CONCLUSIONS: Health-related quality of life improved after ileal pouch anal anastomosis when assessed with both generic and disease-specific measures. Improvements were observed as early as 1 month postoperatively. These results may guide patients and physicians as they consider and prepare for the impact of ileal pouch anal anastomosis.

Irritable pouch syndrome: a new category of diagnosis for symptomatic patients with ileal pouch-anal anastomosis.

OBJECTIVE: Pouchitis often is diagnosed based on symptoms alone. However, increased stool frequency, urgency, and abdominal pain could be due to a condition resembling irritable bowel syndrome. This study was designed to assess the etiology of bowel symptoms using the Pouchitis Disease Activity Index (PDAI). METHODS: Symptoms, endoscopy, and histology were assessed in 61 consecutive symptomatic patients with ulcerative colitis after ileal pouch-anal anastomosis. Pouchitis was defined as a PDAI score of > or = 7, cuffitis was defined as endoscopic and histological inflammation of the rectal cuff and no inflammation of the pouch, and irritable pouch syndrome (IPS) was defined as symptoms with a PDAI of <7 and the absence of cuffitis. RESULTS: Thirty-one patients (50.8%) had pouchitis, four (6.5%) had cuffitis, and 26 (42.6%) had IPS. Demographics were similar in the three groups. Increased stool frequency, urgency, and abdominal cramps were the most common symptoms in the three groups. Rectal bleeding was seen only in cuffitis (p < 0.001). No patient in the three groups had fever. Twenty-seven patients (87.1%) with pouchitis responded to a 2-wk course of ciprofloxacin or metronidazole with a reduction in PDAI scores of > or = 3. All four patients with cuffitis responded to topical hydrocortisone or mesalamine with a reduction in the PDAI symptom component score of > or = 1. Twelve patients with IPS (46.2%) responded to antidiarrheal, anticholinergic, and/or antidepressant therapies with a reduction in the PDAI symptom component score of > or = 1, whereas the remaining patients had persistent symptoms despite therapy. CONCLUSIONS: A substantial number of symptomatic patients after ileal pouch-anal anastomosis do not meet the diagnostic criteria for either pouchitis or cuffitis and have been classified as having IPS. There is an overlap of symptoms among patients with pouchitis, cuffitis, and IPS, and endoscopic evaluation can differentiate among these groups. Distinction between these three groups has therapeutic implications.

Management of Crohn's disease of the ileoanal pouch with infliximab.

OBJECTIVES: The occurrence of Crohn's disease (CD) in a patient with an ileal-pouch anastomosis (IPAA) often results in severe morbidity and significant chance of reservoir loss. We report our experience of the use of infliximab in these patients. METHODS: Medical records of 26 patients with an IPAA and CD-related complications were reviewed. The median time between the IPAA and the diagnosis of CD was 4.5 yr (range 0.1-16 yr). The main reasons for changing the original ulcerative colitis diagnosis to CD were complex perianal or pouch fistulizing disease in 14 patients (54%), prepouch ileitis in five (19%), and both prepouch ileitis and complex fistula in seven (27%). Patients received one to three doses of infliximab over 8 wk as induction therapy. Subsequently the patients received a variable number of maintenance infusions. RESULTS: At a short term follow-up, 16/26 patients (62%) had a complete response, six of 26 (23%) had a partial response, and four of 26 (15%) had no response. Information regarding long term follow-up was available in 24 patients. After a median follow-up of 21.5 months (range 3-44 months), eight patients (33%) either had their pouch resected or had a persistent diverting ileostomy. The pouch was functional in 16/24 (67%) patients, with either good (n = 7) or acceptable (n = 7) clinical results in 14/24 (58%). Of those 14 patients, 11 were under long term, on demand, or systematic maintenance treatment with infliximab. CONCLUSIONS: Infliximab is beneficial in both the short and long term treatment of patients with an IPAA performed for a presumed diagnosis of ulcerative colitis who subsequently develop CD-related complications. Good pouch function requires long term treatment with infliximab in most patients.
