Segmental Colectomy for Ulcerative Colitis: Is There a Place in Selected Patients Without Active Colitis? An International Multicentric Retrospective Study in 72 Patients.

BACKGROUND AND AIMS: The aim of this study was to report a multicentric experience of segmental colectomy [SC] in ulcerative colitis [UC] patients without active colitis, in order to assess if SC can or cannot represent an alternative to ileal pouch-anal anastomosis [IPAA]. METHODS: All UC patients undergoing SC were included. Postoperative complications according to ClavienDindo's classification, long term results, and risk factors for postoperative colitis and reoperation for colitis on the remnant colon, were assessed. RESULTS: A TOTAL OF: 72 UC patients underwent: sigmoidectomy [n = 28], right colectomy [n = 24], proctectomy [n = 11], or left colectomy [n = 9] for colonic cancer [n = 27], 'diverticulitis' [n = 17], colonic stenosis [n = 5], dysplasia or polyps [n = 8], and miscellaneous [n = 15]. Three patients died postoperatively and 5/69 patients [7%] developed early flare of UC within 3 months after SC. After a median followup of 40 months, 24/69 patients [35%] were reoperated after a median delay after SC of 19 months [range, 2-158 months]: 22/24 [92%] underwent total colectomy and ileorectal anastomosis [n = 9] or total coloproctectomy [TCP] [n = 13] and 2/24 [8%] an additional SC. Reasons for reoperation were: colitis [n = 14; 20%], cancer [n = 3] or dysplasia [n = 3], colonic stenosis [n = 1], and unknown reasons [n = 3]. Endoscopic score of colitis before SC was Mayo 23 in 5/5 [100%] patients with early flare vs 15/42 without early flare [36%; p = 0.0101] and in 9/12 [75%] patients with reoperation for colitis vs 11/35 without reoperation [31%; p = 0.016]. CONCLUSIONS: After segmental colectomy in UC patients, postoperative early colitis is rare [7%]. Segmental colectomy could possibly represent an alternative to IPAA in selected UC patients without active colitis.

Decrease in primary but not in secondary abdominal surgery for Crohn's disease: nationwide cohort study, 1990-2014.

BACKGROUND: Treatment of patients with Crohn's disease has evolved in recent decades, with increasing use of immunomodulatory medication since 1990 and biologicals since 1998. In parallel, there has been increased use of active disease monitoring. To what extent these changes have influenced the incidence of primary and repeat surgical resection remains debated. METHODS: In this nationwide cohort study, incident patients of all ages with Crohn's disease, identified in Swedish National Patient Registry between 1990 and 2014, were divided into five calendar periods of diagnosis: 1990-1995 and 1996-2000 with use of inpatient registries, 2001, and 2002-2008 and 2009-2014 with use of inpatient and outpatient registries. The cumulative incidence of first and repeat abdominal surgery (except closure of stomas), by category of surgical procedure, was estimated using the Kaplan-Meier method. RESULTS: Among 21 273 patients with Crohn's disease, the cumulative incidence of first abdominal surgery within 5 years of Crohn's disease diagnosis decreased continuously from 54·8 per cent in 1990-1995 to 40·4 per cent in 1996-2000 (P < 0·001), and again from 19·8 per cent in 2002-2008 to 17·3 per cent in 2009-2014 (P < 0·001). Repeat 5-year surgery rates decreased from 18·9 per cent in 1990-1995 to 16·0 per cent in 1996-2000 (P = 0·009). After 2000, no further significant decreases were observed. CONCLUSION: The 5-year rate of surgical intervention for Crohn's disease has decreased significantly, but the rate of repeat surgery has remained stable despite the introduction of biological therapy.

ANTECEDENTES: El tratamie nto de pacientes con enfermedad de Crohn ha evolucionado en las últimas décadas con un uso cada vez mayor de medicamentos inmunomoduladores desde 1990 y tratamientos biológicos desde 1998. Al mismo tiempo, ha aumentado la utilidad de la vigilancia activa de la enfermedad. Hasta qué punto estos cambios han influido en la incidencia de la resección quirúrgica primaria y repetida sigue siendo objeto de debate. MÉTODOS: Estudio de cohortes a nivel nacional de pacientes incidentes con enfermedad de Crohn de todas las edades identificados en el registro sueco nacional de pacientes entre 1990-2014, que se dividió en cinco períodos de diagnóstico: 1990-1995 y 1996-2000 con el uso de registros de pacientes hospitalizados, 2001, y 2002-2008 y 2009-2014 con uso de registros de pacientes ambulatorios y hospitalizados. Se estimó la incidencia acumulada de la primera cirugía abdominal y de las cirugías abdominales subsiguientes (excepto el cierre de estomas), por categoría de procedimiento quirúrgico, mediante el método de Kaplan-Meier. RESULTADOS: Entre 21.273 pacientes con enfermedad de Crohn, la incidencia acumulada de la primera cirugía abdominal durante los 5 años posteriores al diagnóstico de la enfermedad disminuyó continuamente del 54,8% en la cohorte 1990-1995 al 40,4% en la cohorte 1996-2000 (P < 0,001) y nuevamente del 19,8% en cohorte 2002-2008 al 17,3% en la cohorte 2009-2014 (P < 0,001). Las tasas cirugías iterativas a los 5 años disminuyeron de 18,9% en la cohorte 1990-1995 a 16,0% en la cohorte 1996-2000 (P = 0,017). Después del 2000, no se observaron más disminuciones significativas. CONCLUSIÓN: La tasa de intervención quirúrgica a los 5 años para la enfermedad de Crohn ha disminuido significativamente, pero la cirugía iterativa se ha mantenido estable a pesar de la introducción de la terapia biológica.

Temporary faecal diversion in ileocolic resection for Crohn's disease: is there an impact on long-term surgical recurrence?

AIM: Temporary faecal diversion after ileocolic resection (ICR) for Crohn's disease reduces postoperative anastomotic complications in high-risk patients. The aim of this study was to assess if this approach also reduces long-term surgical recurrence. METHOD: This was a multicentre retrospective review of prospectively maintained databases. Patient demographics, medical and surgical details were collected by three specialist centres. All patients had undergone an ICR between 2000 and 2012. The primary end-point was surgical recurrence. RESULTS: Three hundred and twelve patients (80%) underwent an ICR without covering ileostomy (one stage). Seventy-seven (20%) had undergone an ICR with end ileostomy/double-barrel ileostomy/enterocolostomy followed by closure (two stage). The median follow-up was 105 months [interquartile range (IQR) 76-136 months]. The median time to ileostomy closure was 9 months (IQR 5-12 months). There was no significant difference in surgical recurrence between the one- and two-stage groups (18% vs 16%, P = 0.94). We noted that smokers (20% vs 34%, P = 0.01) and patients with penetrating disease (28% vs 52%, P < 0.01) were more likely to be defunctioned. A reduced recurrence rate was observed in the small high-risk group of patients who were smokers with penetrating disease behaviour treated with a two-stage strategy (0/10 vs 4/7, P = 0.12). CONCLUSION: Despite having higher baseline risk factors, the results in terms of rate of surgical recurrence over 9 years are similar for patients having a two-stage compared with a one-stage procedure.

The Handling of the Rectal Stump Does Not Affect Severe Morbidity After Subtotal Colectomy For Ulcerative Colitis: A Retrospective Cohort Study.

BACKGROUND AND AIMS: Colectomy due to ulcerative colitis is associated with complications. One severe complication is the risk for blow-out of the remaining rectal remnant. The aim of this study was to compare the frequency and severity of complications in patients with the rectal remnant left subcutaneously versus patients with the rectal remnant left intra-abdominally. A secondary aim was to identify risk factors for complications. MATERIALS AND METHODS: Consecutive patients at two tertiary centers in Sweden were retrospectively reviewed regarding surgical procedures; complications classified according to Clavien-Dindo; and possible risk factors for complications such as preoperative medication, emergency surgery, and body mass index. RESULTS: 307 patients were identified. Minor complications were more common than previously reported (85%-89%). Severe surgical complications were not related to the handling of the rectal remnant. Leaving the rectal remnant subcutaneously was associated with local wound problems. Risk factors for severe complications were emergency surgery and preoperative medication with 5-aminosalicylic acid. CONCLUSION: Minor complications after colectomy for ulcerative colitis are very common and need to be addressed. Leaving the rectal stump intra-abdominally seems safe and may be advantageous to reduce local wound morbidity.

Restorative surgery after colectomy for ulcerative colitis in England and Sweden: observations from a comparison of nationwide cohorts.

AIM: A longstanding disparity exists between the approaches to restorative surgery after colectomy for patients with ulcerative colitis (UC) in England and Sweden. This study aims to compare rates of colectomy and restorative surgery in comparable national cohorts. METHOD: The English Hospital Episode Statistics (HES) and Swedish National Patient Register (NPR) were interrogated between 2002 and April 2012. Patients with two diagnostic episodes for UC (age ≥ 15 years) were included. Patients were excluded if they had an episode of inflammatory bowel disease or colectomy before 2002. The cumulative incidences of colectomy and restorative surgery were calculated using the Kaplan-Meier method. RESULTS: A total of 98 691 patients were included in the study, 76 129 in England and 22 562 in Sweden. The 5-year cumulative incidence of all restorative surgery after colectomy in England was 33% vs 46% in Sweden (P-value < 0.001). Of the patients undergoing restorative surgery, 92.3% of English patients had a pouch vs 38.8% in Sweden and 7.7% vs 59.1% respectively had an ileorectal anastomosis (IRA). The 5-year cumulative incidence of colectomy in this study cohort was 13% in England and 6% in Sweden (P-value < 0.001). CONCLUSION: Following colectomy for UC only one-third of English patients and half of Swedish patients underwent restorative surgery. In England nearly all these patients underwent pouches, in Sweden a less significant majority underwent IRAs. It is surprising to demonstrate this discrepancy in a comparable cohort of patients from similar healthcare systems. The causes and consequences of this international variation in management are not fully understood and require further investigation.

Anti-TNF treatment in Crohn's disease and risk of bowel resection-a population based cohort study.

BACKGROUND: TNF inhibitors (TNFi) have been shown to reduce the need for surgery in Crohn's disease, but few studies have examined their effect beyond the first year of treatment. AIM: To conduct a register-based observational cohort study in Sweden 2006-2014 to investigate the risk of bowel resection in bowel surgery naïve TNFi-treated Crohn's disease patients and whether patients on TNFi ≥12 months are less likely to undergo bowel resection than patients discontinuing treatment before 12 months. METHODS: We identified all individuals in Sweden with Crohn's disease through the Swedish National Patient Register 1987-2014 and evaluated the incidence of bowel resection after first ever dispensation of adalimumab or infliximab from 2006 and up to 7 years follow-up. RESULTS: We identified 1856 Crohn's disease patients who had received TNFi. Among these patients, 90% treatment retention was observed at 6 months after start of TNFi and 65% remained on the drug after 12 months. The cumulative rates of surgery in Crohn's disease patients exposed to TNFi years 1-7 were 7%, 13%, 17%, 20%, 23%, 25% and 28%. Rates of bowel resection were similar between patients with TNFi survival <12 months and ≥12 months respectively (P=.27). No predictors (eg, sex, age, extension or duration of disease) for bowel resection were identified. CONCLUSIONS: The risk of bowel resection after start of anti-TNF treatment is higher in regular health care than in published RCTs. Patients on sustained TNFi treatment beyond 12 months have bowel resection rates similar to those who discontinue TNFi treatment earlier.

Surgical and not analgesic technique affects postoperative inflammation following colorectal cancer surgery: a prospective, randomized study.

AIM: Epidural analgesia reduces the surgical stress response. However, its effect on pro- and anti-inflammatory cytokines in the genesis of inflammation following major abdominal surgery remains unclear. Our main objective was to elucidate whether perioperative epidural analgesia prevents the inflammatory response following colorectal cancer surgery. METHODS: Ninety-six patients scheduled for open or laparoscopic surgery were randomized to epidural analgesia (group E) or patient-controlled intravenous analgesia (group P). Surgery and anaesthesia were standardized in both groups. Plasma cortisol, insulin and serum cytokines [interleukin 1ß (IL-1ß), IL-4, IL-5, IL-6, IL-8, IL-10, IL-12p70, IL-13, tumour necrosis factor α, interferon γ, granulocyte-macrophage colony-stimulating factor, prostaglandin E2 and vascular endothelial growth factor] were measured preoperatively (T0), 1-6 h postoperatively (T1) and 3-5 days postoperatively (T2). Mixed model analysis was used, after logarithmic transformation when appropriate, for analyses of cytokines and stress markers. RESULTS: >There were no significant differences in any serum cytokine concentration between groups P and E at any time point except for IL-10 which was 87% higher in group P [median and range 4.1 (2.3-9.2) pg/ml] compared to group E [2.6 (1.3-4.7) pg/ml] (P = 0.002) at T1. There was no difference in plasma cortisol and insulin between the groups at any time point after surgery. A significant difference in median serum cytokine concentration was found between open and laparoscopic surgery with higher levels of IL-6, IL-8 and IL-10 at T1 in patients undergoing open surgery compared to laparoscopic surgery. No difference in serum cytokine concentration was detected between the groups or between the surgical technique at T2. CONCLUSIONS: Open surgery, compared to laparoscopic surgery, has greater impact on these inflammatory mediators than epidural analgesia vs intravenous analgesia.

The role of a defunctioning stoma for colonic and perianal Crohn's disease in the biological era.

OBJECTIVE: A defunctioning stoma is a therapeutic option for colonic or perianal Crohn's disease. In the pre-biologic era the response rate to defunctioning in our unit was high (86%), but intestinal continuity was only restored in 11-20%. Few data exist on the outcome of defunctioning since the widespread introduction of biologicals. MATERIAL AND METHODS: All patients undergoing a defunctioning stoma for colonic/perianal Crohn's disease since 2003-2011 were identified from a prospective database. Indications for surgery, medical therapy, response to defunctioning and long-term clinical outcome were recorded. Successful restoration of continuity was defined as no stoma at last follow up. RESULTS: Seventy-six patients were defunctioned (57 with biologicals) and at last follow up, 20 (27%) had continuity restored. Early clinical response rate (<3 months) was 15/76 (20%) and overall response 31/76 (41%). Complex anal fistulae/stenosis were associated with a very low chance of restoring continuity (10% and 0%, respectively), while colitis was associated with a higher chance of restoring continuity (48%). Endoscopic or histological improvement in colitis after defunctioning was associated with a higher rate of restoring continuity (10/16, 63%) compared to no such improvement (4/15, 27%, p = 0.05). Those failing biologics had similar chance of restoration as those not receiving biologics, 15/57 (26%) and 5/19 (26%), respectively. CONCLUSION: Overall response to colonic defunctioning was 41%. Successful restoration of continuity occurred in 27%, but 48% in the absence of perianal disease. Response is appreciably less in the pre-biologic era, so patient and physician expectations need to be managed appropriately.

Probability, rate and timing of reconstructive surgery following colectomy for inflammatory bowel disease in Sweden: a population-based cohort study.

AIM: Many patients with inflammatory bowel disease (IBD) need colectomy, but the rate of reconstructive surgery with restoration of intestinal continuity is unknown. The aim of this study was to investigate the probability, rate and timing of reconstructive surgery after colectomy in patients with IBD in a population-based setting. METHOD: The study cohort included all patients with IBD in Sweden who underwent colectomy from 2000 to 2009. Each patient was followed from admission for colectomy to admission for reconstructive surgery, date of death, migration or 31 December 2010. Kaplan-Meier survival curves and multivariable Poisson regression models were used to describe the probability, rate and timing of reconstructive surgery. RESULTS: Out of 2818 IBD patients treated with colectomy, 61.0% were male and 78.9% had ulcerative colitis. No reconstructive surgery had been performed in 1595 (56.6%) patients by the end of follow-up. Of the remaining 1223 patients, 526 underwent primary reconstructive surgery and 697 had a secondary reconstruction following a median interval of 357 days from primary surgery in the form of colectomy. The probability of reconstructive surgery was dependent on age (55.6% and 18.1% at ages 15-29 and ≥ 59 years, respectively), and the chance of reconstructive surgery was higher in hospitals that performed more than 13 colectomies for IBD per year [incidence rate ratio and 95% confidence interval 1.27 (1.09-1.49)]. CONCLUSION: Fewer than half of the patients having a colectomy for IBD underwent subsequent reconstructive surgery. Older age and low hospital volume were risk factors for no reconstructive surgery.

Complications in surgery for Crohn's disease after preoperative antitumour necrosis factor therapy.

BACKGROUND: The use of biological therapy (biologicals) is established in the treatment of Crohn's disease. This study aimed to determine whether preoperative treatment with biologicals is associated with an increased rate of complications following surgery for Crohn's disease with intestinal anastomosis. METHODS: All patients receiving biologicals and undergoing abdominal surgery with anastomosis or strictureplasty were identified at six tertiary referral centres. Demographic data, and preoperative, operative and postoperative details were registered. Patients who were treated with biologicals within 2 months before surgery were compared with a control group who were not. Postoperative complications were classified according to anastomotic, infectious or other complications, and graded according to the Clavien-Dindo classification. RESULTS: Some 111 patients treated with biologicals within 2 months before surgery were compared with 187 patients in the control group. The groups were well matched. There were no differences between the treatment and control groups in the rate of complications of any type (34·2 versus 28·9 per cent respectively; P = 0·402), anastomotic complications (7·2 versus 8·0 per cent; P = 0·976) and non-anastomotic infectious complications (16·2 versus 13·9 per cent; P = 0·586). In univariable regression analysis, biologicals were not associated with an increased risk of any complication (odds ratio (OR) 1·33, 95 per cent confidence interval 0·81 to 2·20), anastomotic complication (OR 0·89, 0·37 to 2·17) or infectious complication (OR 1·09, 0·62 to 1·91). CONCLUSION: Treatment with biologicals within 2 months of surgery for Crohn's disease with intestinal anastomosis was not associated with an increased risk of complications.

Split stoma in resectional surgery of high-risk patients with ileocolonic Crohn's disease.

AIM: The aim of this retrospective study of ileocolonic resection in patients with Crohn's disease was to compare the outcome of primary anastomosis with that of split stoma and delayed anastomosis in a high-risk setting. METHOD: From 1995 to 2006, 132 patients had 146 operations for ileocolonic Crohn's disease. Preoperative data, including risk factors for complications, were obtained from a prospectively registered database. Operations on patients who had two or more preoperative risk factors (n = 76) were considered to be high-risk operations and formed the main study. Primary outcome variables were postoperative anastomotic complications and the alteration in the number of preoperative risk factors achieved by a delayed anastomosis. Secondary outcome was time in hospital and the number of operations performed. RESULTS: Early anastomotic complications were diagnosed in 19% (11/57) of patients receiving a primary anastomosis compared with 0% (0/19) of patients after a delayed anastomosis (P = 0.038). The mean number of risk factors in the split stoma group was 3.5 at the time of resection and 0.2 when the split stoma was reversed (P < 0.0001). The total number of operations was 1.9 ± 1.5 (mean ± SD) after a primary anastomosis and 2.0 ± 0.2 after a split stoma (P = 0.70). Total in-hospital time for all operations was 20.9 ± 35.6 days after a primary anastomosis and 17.8 ± 10.4 days after a delayed anastomosis (P = 0.74). CONCLUSION: Delayed anastomosis after ileocolonic resection in high-risk Crohn's disease patients was associated with a reduction in the number of preoperative risk factors and fewer anastomotic complications. Hospital stay and number of operations were similar after delayed and primary anastomosis in high-risk patients.

Randomized clinical trial of groin hernia repair with titanium-coated lightweight mesh compared with standard polypropylene mesh.

BACKGROUND: Groin hernia repair is one of the commonest operations in general surgery. Existing techniques have very low and acceptable recurrence rates, but chronic pain and discomfort remain a problem for many patients. New mesh materials are being developed to increase biocompatibility, and the aim of this study was to compare a new titanium-coated lightweight mesh with a standard polypropylene mesh. METHODS: A randomized controlled single-centre clinical trial was designed, with the basic principle of one unit, one surgeon, one technique (Lichtenstein under general anaesthesia) and two meshes. Pain before and after surgery, and during convalescence (primary outcomes) was estimated in 317 patients. At 1-year clinical follow-up, recurrence, pain, discomfort and quality of life (secondary outcomes) were evaluated. RESULTS: Patients with the lightweight mesh returned to work after 4 days, compared with 6.5 days for the standard mesh (P = 0.040). The lightweight group returned to normal activity after 7 days, versus 10 days for the standard group (P = 0.005). There was no difference in postoperative pain or recurrence at the 1-year follow-up. CONCLUSION: Patients with the lightweight mesh had a shorter convalescence than those with the standard heavyweight mesh. REGISTRATION NUMBER: ISRCTN36979348 (http://www.controlled-trials.com).

Atopic manifestations are more common in patients with Crohn disease than in the general population.

BACKGROUND: The role of TNF-alpha in Crohn disease is now well established and anti-TNF-alpha is frequently used as a second- or third-line treatment. Tumor necrosis factor-alpha (TNF-alpha) is traditionally associated with macrophages but has recently also been found in mast cells of the ileal wall in patients with Crohn disease. As it is well known that mast cells and TNF-alpha play important roles in atopic manifestations like asthma, allergic rhinitis; and eczema the aim of this study was to investigate whether these are seen more commonly in Crohn patients than in the general population. METHODS: Patients with Crohn disease (n = 308), aged 18-50 years, living in the Linköping region in southeast Sweden, were asked to answer a questionnaire regarding the presence of any kind of atopic manifestations. The questionnaire was also sent to 930 controls collected from the Southeastern Region Population Registry. The controls were matched according to age, sex, and place of residence. RESULTS: The response rate among the Crohn patients was 91% (280/308) and among controls 84% (779/930). Eczema was a significantly more frequent manifestation, being almost twice as common in Crohn patients (27%) as in the general population (16%). Adjustment by logistic regression for place of residence, gender, age and coexistence of any other atopic manifestation did not change the odds ratios significantly. CONCLUSION: Atopic manifestations as a group, and eczema as a single manifestation, are significantly more frequent in Crohn patients than in the general population.

Anal and rectal cancer in Crohn's disease.

Several epidemiological studies have been published regarding the risk of Crohn's disease- associated colorectal cancer. The findings are, however, contradictory and it has been particularly difficult to obtain indisputable information on the incidence of cancer limited to the rectum and the anus. During 1987-2000 rectal or anal cancer was diagnosed in 335 patients in Sweden (153 males, 182 females). In other words, approximately 3 Crohn patients per million inhabitants were diagnosed with rectal or anal cancer every year during that time period which is 1% of the total number of cases. At diagnosis of cancer 36% were aged below 50 years and 58% below 60 years. Corresponding figures for all cases of anal and rectal cancer were 5% and 18%, respectively. Present knowledge from the literature implies that there is an increased risk of rectal and anal cancer only in Crohn's disease patients with severe proctitis or severe chronic perianal disease. However, the rectal remnant must also be considered a risk factor. Multimodal treatment is similar to that in sporadic cancer but proctectomy and total or partial colectomy is added depending on the extent of the Crohn's disease. The outcome is the same as in sporadic cancer at a corresponding stage but the prognosis is often poor due to the advanced stage of cancer at diagnosis. We suggest that six high-risk groups should be recommended annual surveillance after a duration of Crohn's disease of 15 years including extensive colitis, chronic severe anorectal disease, rectal remnant, strictures, bypassed segments and sclerosing cholangitis.

Health related quality of life in Crohn's proctocolitis does not differ from a general population when in remission.

OBJECTIVE: All treatment in Crohn's disease, although palliative, aims at restoring full health. The objective of this study was to compare health-related quality of life and psychosocial conditions in patients with Crohn's proctocolitis with a general population. PATIENTS AND METHODS: One hundred and twenty-seven patients with Crohn's proctocolitis (median age 44 years, 44.1% men) were compared with 266 controls (median age 45 years, 50.7% men). A questionnaire consisting of the Short Form-36 (SF-36), the Psychological General Well-Being Index (PGWB) and a visual analogue scale (VAS) evaluating general health as well as questions regarding psychosocial conditions was used. Disease activity was evaluated by Best's modification of the classical Crohn's Disease Activity Index. RESULTS: Patients in remission had a health related quality of life similar to controls according to the SF-36 apart from general health where scores were lower (P < 0.01). Patients with active disease scored lower in all aspects of the SF-36 (P < 0.001 or P < 0.0001) as well as the PGWB (P < 0.0001). In a model for multiple regression including age, gender, concomitant small bowel disease, permanent stoma, previous colonic surgery, disease activity, duration, and aggressiveness, disease activity was the only variable negatively predicting all 8 domains of the SF-36 in the patient group (P < 0.001). The mean annual sick-leave for patients and controls were 33.9 and 9.5 days (P < 0.0001), respectively. Sixty-eight percent of the patients and 78.4% of the controls (P = 0.04) were married or cohabited, 67.7% and 78.0% (P = 0.04), respectively, had children. CONCLUSION: The health related quality of life for patients with Crohn's proctocolitis in remission does not differ from the general population. The disease has, however, a negative impact on parenthood, family life and professional performance.
