Influence of ileal pouch anal anastomosis on bone loss in ulcerative colitis patients

Background and aim

Patients with ulcerative colitis (UC) are at an increased risk for low bone mineral density (BMD). It is unclear whether proctocolectomy with ileal pouch-anal anastomosis (IPAA) for UC alters the risk of bone loss. The aim of this study was to compare BMD in UC patients with and without IPAA.

Methods

A total of 267 patients with UC and IPAA (study group) were compared to 119 UC patients without IPAA (control group) in this cross-sectional study. The demographic and clinical variables including dual-energy X-ray absorptiometry scan results were compared. Patients were classified as having normal or low BMD, based on the criteria by the International Society for Clinical Densitometry. Univariate and multivariate analyses were performed to assess risk factors associated with low BMD. Age, gender, race, smoking status, steroid use, alcohol use, body mass index, years of absent estrogen protection, use of calcium, vitamin D supplements and disease duration were selected as covariates.

Results

83 (31.1%) had low BMD in the study group vs. 18 (15.1%) in the control group (p = 0.001). 2/13 (15.4%) had low BMD before surgery. The mean age of patients in the study and control groups were 44.7 ± 14.1 vs. 52.4 ± 17.7 years, respectively (p < 0.001). The hip BMD was lower in the study group (0.93 ± 0.17 g/cm2) than that in the control group (0.98 ± 0.17 g/cm2) (p = 0.038). Fragility fracture was documented in 23 (8.6%) patients in the study group vs. 3 (2.5%) in the control group (p = 0.038) Sixty-four (24.0%) of the study group patients were using corticosteroids after surgery in contrast to 93 (78.2%) in the control group (p < 0.001). On multivariable analyses, covariate adjusted factors associated with a low BMD in UC patients were advanced age [odds ratio (OR) 1.51 per 5 years; 95% confidence interval [CI], 1.34–1.71], low body mass index (OR = 2.37 per 5 kg/m² decrease; 95% CI, 1.68–3.36), and the presence of IPAA (OR = 6.02; 95% CI, 2.46–14.70). For the 13 IPAA patients who had information available, BMD before IPAA was low. After a median of 46 (Range 7–84) months after IPAA, BMD improved in 7/13 patients (53.8%), while it continued to be low in 6/13 (46.2%) patients.

Conclusions

Low BMD is common in patients with UC. The risk appears to persist even after colectomy and IPAA surgery suggesting that these patients need to be monitored for bone loss.     

Biopsychosocial determinants of health-related quality of life after ileal pouch anal anastomosis for ulcerative colitis

BACKGROUND: In patients with ileal pouch anal anastomosis (IPAA) the influences of psychosocial variables and of extraintestinal manifestations of ulcerative colitis (UC) on health-related quality of life (HRQOL) have not been studied so far. METHODS: 61 patients with UC (age 52.7+/-13.9 years; 47% female) completed the German version of the Inflammatory Bowel Disease Questionnaire (IBDQ-D), the Short Form Health Survey (SF - 36), the German version of the Hospital Anxiety and Depression Scale (HADS-D) and the Giessener Symptom List (GBB 24). Independent of their current clinical activity 37 patients underwent endoscopies. Pouchitis was defined by the Pouch Disease Activity Score (PDAI) > or = 7. Where possible, IPAA-patients were compared with the data for the German general population and with a clinical sample of patients with UC and no IPAA. RESULTS: Patients with IPAA complained more about fatigue and arthralgia and a reduced physical and mental health (SF-36) than the German general population (P < 0.01). The IBDQ-total score could be predicted (adjusted R2 = 29.1, P < 0.01) by the number of operations due to IPAA-related complications (beta = -18.8) and HADS-D-Anxiety scores > or = 11 (beta = -29.1). The IBDQ-subscale score "Bowel" could be predicted (adjusted R2 = 13.7, P = 0.04) by PDAI > or = 7 (beta = -9.2) and the subscale score "Systemic" (adjusted R2 = 13.3, P = 0.04) by the number of extraintestinal manifestations (beta = -1.9). CONCLUSIONS: HRQOL of patients with UC and IPAA is determined not only by IPAA-related factors but also by anxiety and extraintestinal manifestations with associated musculoskeletal pain.     

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.     

Long-term functional outcome after ileal pouch anal anastomosis in 191 patients with ulcerative colitis

BackgroundA long-lasting good functional outcome of the pelvic pouch and a subsequent satisfying quality of life (QoL) are mandatory. Long-term functional outcome and QoL in a single-center cohort were assessed.Patients and methodsA questionnaire was sent to all patients with an IPAA for UC, operated between 1990 and 2010 in our department. Pouch function was assessed using the Öresland Score (OS) and the ‘Pouch Functional Score’ (PFS). QoL was assessed using a Visual Analogue Score (VAS).Results250 patients (42% females) with a median age at surgery of 38 years (interquartile range (IQR): 29–48 years) underwent restorative proctocolectomy. Median follow‐up was 11 years (IQR: 6–17 years). Response rate was 81% (n = 191). Overall pouch function was satisfactory with a median OS of 6/15 (IQR: 4–8) and a median PFS of 6/30 (IQR: 3–11). 24-hour bowel movement is limited to 8 times in 68% of patients (n = 129), while 55 patients (29%) had less than 6 bowel movements. 12 patients (6.5%) were regularly incontinent for stools, while 154 patients (82%) reported a good fecal continence. Fecal incontinence during nighttime was more common (n = 72, 39%). Pouch function had little impact on social activity (4/10; IQR: 2–6) and on professional activity (3/10; IQR: 1–6). 172 patients (90%) reported to experience an overall better health condition since their operation. The OS and the PFS correlated well (Pearson's correlation coefficient = 0.83). Overall pouch function was stable over time.ConclusionMajority of patients report a good pouch function on the long-term with limited impact on QoL.     

Outcome after proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis

BACKGROUND: During the course of their disease, about 30% of patients with ulcerative colitis (UC) will undergo proctocolectomy with ileal pouch-anal anastomosis (IPAA). We evaluated the outcome of IPAA in a Belgian referral center. METHODS: Clinical charts were reviewed for pre- and postoperative disease course, functional outcome, and complications in all patients with UC (n = 182) and indeterminate colitis (n = 2) who underwent IPAA in 1990-2004. RESULTS: Follow-up data were available in 173 out of 184 patients (67 female, median age at proctocolectomy 39.0 years). Median functional Oresland score 1 year after IPAA was 3 (range 0-11). Early postoperative complications were seen in 27% of patients. After a median (interquartile range) follow-up of 6.5 (3.4-9.9) years, 35% of patients developed septic and/or obstructive complications. Forty-six percent of patients developed at least 1 episode of pouchitis. Risk factors for pouchitis were the presence of extraintestinal manifestations (odds ratio [OR] 1.92 (1.23-3.01), P = 0.004) and younger age at proctocolectomy (P = 0.004). Chronic pouchitis was present in 33 patients and associated with extraintestinal manifestations (OR 2.93 (1.13-7.62), P = 0.027), backwash ileitis (OR 9.28 (1.71-50.49), P = 0.010), and length of follow-up (P = 0.004). Pouch failure occurred in 5% of patients. CONCLUSIONS: Although proctocolectomy with IPAA surgery has a good functional outcome, postoperative complications, especially pouchitis, remain considerable in patients with UC.

Assessment of the Japanese Inflammatory Bowel Disease Questionnaire in patients after ileal pouch anal anastomosis for ulcerative colitis

Background The Inflammatory Bowel Disease Questionnaire (IBDQ) is the most widely used disease-specific health-related quality of life questionnaire for patients with inflammatory bowel disease. However, little has been reported about the validation of IBDQ for patients with ulcerative colitis after surgery. The aim of this study was to assess the validity and reliability of the Japanese version of IBDQ in patients with ulcerative colitis after total proctocolectomy and ileal pouch anal anastomosis (IPAA). Methods The validity and reliability of the Japanese IBDQ were assessed in patients with ulcerative colitis who had received IPAA in our hospital. We mailed them the Japanese IBDQ and a supplemental questionnaire on bowel function, which was developed at our institution. Internal consistency, discriminative validity, and factor validity were assessed. Results Of the 121 patients to whom we sent the questionnaires, 64 patients (53%) participated in this study. The Japanese IBDQ scores correlated well with Cronbach's alpha value (0.800 to 0.923) and daily life satisfaction score (Pearson's r, 0.492 to 0.700). The total IBDQ score and two subscale scores of the IBDQ, “bowel symptoms” and “systemic symptoms,” correlated well with daily bowel-movement frequency (Pearson's r, −0.256 to −0.329). Factor analysis revealed a four-factor structure, and all correlations among factors were moderately positive (0.337 to 0.465). Although the factor distribution was not clearly divided into the four IBDQ subscales, these four factors showed a marked tendency to represent the IBDQ subscales independently. Conclusions The Japanese IBDQ is a valid and reliable instrument for the assessment of Japanese patients with ulcerative colitis after IPAA.     

Risk of osteopenia after proctocolectomy and ileal pouch-anal anastomosis for ulcerative colitis

BACKGROUND: The aim of our study was to evaluate the influence of pouchitis and villous atrophy on bone mineral density and metabolism at least 5 years after ileal pouch-anal anastomosis for ulcerative colitis (UC). METHODS: Eighty-eight subjects with a J-pouch operated on between 1985 and 1994, and 20 ulcerative colitis subjects with a conventional ileostomy were enrolled. Endoscopy was performed and spine and femoral neck bone mineral densities measured. Bone metabolism was assessed by measurement of serum levels of parathyroid hormone, osteocalcin, 25-hydroxyvitamin D3, calcium, alkaline phosphatase and urinary N-telopeptide cross-linked of type I collagen (NTX). RESULTS: In the lumbar spine, 37% of the J-pouch subjects with subtotal to total villous atrophy had osteopenia (Z score <-1), whereas none of the subjects with normal villous structure had reduced bone densities in the spine or femoral neck. The highest prevalence of osteopenia (66.7%) and the lowest spine (mean -0.89+/-0.36; P = 0.006) and femoral neck (mean -0.63+/-0.29; P = 0.07) Z scores were found among the patients (n = 12) with inflammation in the proximal limb of the pouch. No biochemical parameters were found to predict osteopenia and in stepwise regression analysis, the only independent risk factors for osteopenia were low body mass index and villous atrophy. CONCLUSIONS: Patients with a J-pouch showing high inflammatory activity and villous atrophy in the pouch need long-term follow-up and should be ensured adequate intake of calcium and vitamin D.     

Threefold increased risk of infertility: a meta-analysis of infertility after ileal pouch anal anastomosis in ulcerative colitis

BACKGROUND: Increased infertility in women has been reported after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis but reported infertility rates vary substantially. AIMS: (1) To perform a systematic review and meta-analysis of the relative risk of infertility post-IPAA compared with medical management; (2) to estimate the rate of infertility post-IPAA; and (3) to identify modifiable risk factors which contribute to infertility. METHODS: Medline, EMBASE, Current Contents, meeting abstracts, and bibliographies were searched independently by two investigators. The titles and abstracts of 189 potentially relevant studies were reviewed; eight met the criteria and all data were extracted independently. Consensus was achieved on each data point, and fixed effects meta-analyses, a funnel plot, and sensitivity analyses were performed. RESULTS: The initial meta-analysis of eight studies had significant heterogeneity (p = 0.004) due to one study with very high preoperative infertility (38%). When this study was omitted, the relative risk of infertility after IPAA was 3.17 (2.41-4.18), with non-significant heterogeneity. The weighted average infertility rate in medically treated ulcerative colitis was 15% for all seven studies, and the weighted average infertility rate was 48% after IPAA (50% if all eight studies are included). We were unable to identify any procedural factors that consistently affected the risk of infertility. CONCLUSIONS: IPAA increases the risk of infertility in women with ulcerative colitis by approximately threefold. Infertility, defined as achieving pregnancy in 12 months of attempting conception, increased from 15% to 48% in women post-IPAA for ulcerative colitis. This provides a basis for counselling patients considering colectomy with IPAA. Further studies of modifiable risk factors are needed.     

Comparative clinical results of ileal-pouch anal anastomosis and ileorectal anastomosis in ulcerative colitis

The aim of the study was to compare the results of ileal-pouch anal anastomosis (IAA) and total abdominal colectomy with ileorectal anastomosis (IRA) in the treatment of ulcerative colitis. The number of patients included in the comparative trial was 104 (IAA) and 197 (IRA), respectively. No clear advantage of IRA over IAA was seen: postoperative mortality and morbidity were about the same; functional results as shown by the frequency of stools and daytime continence were virtually equal. A factor favoring IAA was, among others, recurrence of proctitis after IRA which is more difficult to treat than the pouchitis occurring after IAA and is associated with a higher rate of secondary permanent end ileostomy; besides, IRA entails the risk of cancer developing in the rectal stump, while at the same time it is difficult to follow up these patients closely enough. IRA is indicated only if the diagnosis of ulcerative colitis is in doubt; if the patient is more than 60 years of age; and if IAA proves technically too difficult, IAA is usually preferable, however, if there is any doubt as to whether the patient is suffering from ulcerative colitis or Crohn's disease, ileorectostomy is preferred which does not preclude IAA at a later date in case of need.     

Pouchitis after ileal pouch‐anal anastomosis in ulcerative colitis: Diagnosis,management, risk factors,and incidence

Restorative proctocolectomy with ileal pouch‐anal anastomosis has been the surgical treatment of choice for patients with ulcerative colitis who require surgery. Quality of life after this procedure is satisfactory in most cases; however, pouchitis is a troublesome condition involving inflammation of the ileal pouch. When a patient presents with symptoms of pouchitis, such as increased bowel movements, mucous and/or bloody exudates, abdominal cramps, and fever, endoscopy is essential for a precise diagnosis. The proximal ileum and rectal cuff, as well as the ileal pouch, should be endoscopically observed. The reported incidence of pouchitis ranges from 14% to 59%, and antibiotic therapy is the primary treatment for acute pouchitis. Chronic pouchitis includes antibiotic‐dependent and refractory pouchitis. Intensive therapy including antitumor necrosis factor antibodies and steroids may be necessary for antibiotic‐refractory pouchitis, and pouch failure may occur despite such intensive treatment. Reported risk factors for the development of pouchitis include presence of extraintestinal manifestations, primary sclerosing cholangitis, non‐smoking, and postoperative non‐steroidal anti‐inflammatory drug usage. In the present review, we focus on the diagnosis, endoscopic features, management, incidence, and risk factors of pouchitis in patients with ulcerative colitis who underwent ileal pouch‐anal anastomosis.     

Long-term quality of life after ileal pouch anal restorative proctocolectomy for ulcerative colitis

Restorative proctocolectomy with ileal pouch anal anastomosis (IPAA) has evolved as the surgical procedure of choice for ulcerative colitis (UC). The aim of our study was to evaluate the quality of life (QOL) of UC patients who underwent this procedure over 5 years ago. Thirty-nine UC patients who underwent restorative proctocolectomy with IPAA were interviewed by the validated inflammatory bowel disease questionnaire (IBDQ). Each patient was assigned a score, ranging from 32 to 224, in which the highest score indicates the best QOL. QOL for postoperative patients was good in 15 (38.5 %), regular in 23 (59 %), and bad in 1 (2.6 %) patient. QOL was not significantly influenced by age or gender of the patient. The emotional aspect received the highest score in the IBDQ and for each question that was analyzed separately; most of the patients were pleased and thankful with their lives and this question received the highest score. Long-term QOL was good in UC patients who underwent IPAA. This operation should be considered as the first choice since the patients were stable after long-term follow up.     

Physiology of ileoanal anastomosis with ileal reservoir for ulcerative colitis and adenomatosis coli

A physiologic and metabolic assessment was carried out on eight patients six months after total proctocolectomy with ileal reservoir for ulcerative colitis and familial adenomatosis coli. All patients were continent and able to defecate spontaneously, stool frequency ranging from two to five per 24 hours. Anal sphincter resting pressures (35±14 mmHg) and squeeze pressures (88±24.2 mmHg) were similar to those of a healthy population, with the exception of one patient's complaint of nocturnal mucous leakage per anus. Biopsies of the ileal mucosa of the reservoirs showed a mild inflammation in seven patients; in one a subtotal villous atrophy (plus glandular pattern) was found. Anthropometric measurements, lymphocyte counts, hemoglobin, albumin, transferrin, iron, B₁₂, and folate were normal in all. In the majority of patients there was no evidence of bacterial overgrowth. Vitamin B₁₂ absorption was reduced slightly in only one patient. Lipid absorption (as judged by the¹⁴C-Triolein breath test) was abnormal in three patients. Fecal clearance of α₁ antitrypsin as protein losses index was abnormal in three patients. Bile acid malabsorption was the most important ileal dysfunction observed in the patients.     

Complications after ileal pouch-anal anastomosis in Korean patients with ulcerative colitis

AIM: To investigate the outcomes of treatments for complications after ileal pouch-anal anastomosis (IPAA) in Korean patients with ulcerative colitis.METHODS: Between March 1998 and February 2013, 72 patients (28 male and 44 female, median age 43.0 years ± 14.0 years) underwent total proctocolectomy with IPAA. The study cohort was registered prospectively and analyzed retrospectively. Patient characteristics, medical management histories, operative findings, pathology reports and postoperative clinical courses, including early postoperative and late complications and their treatments, were reviewed from a medical record system. All of the ileal pouches were J-pouch and were performed with either the double-stapling technique (n = 69) or a hand-sewn (n = 3) technique.RESULTS: Thirty-one (43.1%) patients had early complications, with 12 (16.7%) patients with complications related to the pouch. Pouch bleeding, pelvic abscesses and anastomosis ruptures were managed conservatively. Patients with pelvic abscesses were treated with surgical drainage. Twenty-seven (38.0%) patients had late complications during the follow-up period (82.5 ± 50.8 mo), with 21 (29.6%) patients with complications related to the pouch. Treatment for pouchitis included antibiotics or anti-inflammatory drugs. Pouch-vaginal fistulas, perianal abscesses or fistulas and anastomosis strictures were treated surgically. Pouch failure developed in two patients (2.8%). Analyses showed that an emergency operation was a significant risk factor for early pouch-related complications compared to elective procedures (55.6% vs 11.1%, P < 0.05). Pouchitis was related to early (35.3%) and the other late pouch-related complications (41.2%) (P < 0.05). The complications did not have an effect on pouch failure nor pouch function.CONCLUSION: The complications following IPAA can be treated successfully. Favorable long-term outcomes were achieved with a lower pouch failure rate than reported in Western patients.     

Absorption studies after ileal J-pouch anastomosis for ulcerative colitis. A prospective study

Absorption studies were performed in 17 patients with ulcerative colitis operated on with colectomy and an ileal two-limbed J-pouch anastomosis. The patients were studied 3 and greater than or equal to 18 months after closure of the temporary ileostomy. Increased stool mass (median, 609 g/24 h) was found in all patients and was unchanged with time. Moderate steatorrhoea was present in 29% of the patients 3 months postoperatively, but faecal fat excretion normalized with time. Calcium absorption was normal in all but one patient regardless of time after operation. An abnormal bacterial deconjugation, evaluated by a 14C-glycocholic acid breath test was present in 27% of the patients and increased significantly with time. Forty per cent of the patients had increased faecal bile acid excretion. B12 malabsorption was present in 29-35% of the patients. In conclusion, ileal J-pouch anastomosis for ulcerative colitis causes increased stool mass in all patients and produces moderate bile acid deconjugation and malabsorption in about one-third to half. Substitution therapy with vitamin B12 is necessary in about one-third of the patients. Intestinal adaptation as far as absorption is concerned is minimal after the first 3 postoperative months.     

Assessment of mucosal inflammation and circulation in response to probiotics in patients operated with ileal pouch anal anastomosis for ulcerative colitis

BACKGROUND: Pouchitis is a common and troublesome condition, and a disturbed microbiological flora and mucosal blood flow in the pouch have been suggested as possible causes. Laser Doppler flowmetry (LDF) has been used successfully to measure gastric and colonic mucosal perfusion in humans. The aim of this study was to evaluate the effect of intervention with probiotics on ileal pouch inflammation and perfusion in the pouch, assessed by endoscopy, histology, fecal calprotectin and LDF. METHODS: A fermented milk product (Cultura; 500 ml) containing live lactobacilli (La-5) and bifidobacteria (Bb-12) was given daily for 4 weeks to 10 patients operated with ileal-pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). Mucosal perfusion was measured with LDF and the degree of inflammation was examined at predefined levels of the distal bowel by endoscopy and histology. Stool samples were cultured for lactobacilli and bifidobacteria and calprotectin were measured before and after intervention. RESULTS: The LDF measurements were reproducible in the pelvic pouch at each of the predefined levels, but did not change after intervention. The mucosal perfusion was reduced in the distal compared to the proximal part of the pouch. Calprotectin levels did not change significantly after intervention. The median endoscopic score for inflammation was significantly reduced by 50% after intervention, whereas the histological score did not change significantly. CONCLUSION: The results suggest that probiotics primarily act superficially, with change of gross appearance of the mucosa at endoscopy, but without significant effect on histological picture, mucosal perfusion or faecal calprotectin, during a relatively short period of 4 weeks.
