Long-term follow-up of patients with Crohn's disease. Relationship between the clinical pattern and prognosis

In a study of 615 new patients with Crohn's disease consecutively diagnosed at the Cleveland Clinic between 1966 and 1969, 592 patients were observed (mean greater than 13 yr, minimum 7 yr), giving a follow-up rate of 96.3%. The original hypothesis was that initial anatomic involvement (the clinical pattern) bears directly on clinical course and prognosis. Disease sites were as follows: 246 ileocolic, 165 small intestine, and 181 colon/anorectal. Among patients with ileocolic disease, 225 (91.5%) had surgery. For the small intestine pattern, the operative incidence was 65.5%; for the colon/anorectal pattern, it was 58%. Operations were for specific reasons: internal fistula with abscess or intestinal obstruction for ileocolic pattern; intestinal obstruction for small intestine pattern; and severe perianal disease or toxic megacolon for colon/anorectal pattern. Complications among nonoperated patients included perianal fistulas and extraintestinal manifestations. No statistical correlation existed between type and duration of medical treatment and prognosis. Seventy-five deaths occurred (12.8%), 36 of which related directly to Crohn's disease. Even after many years, symptoms continued and quality of life tended to be suboptimal among operated patients. For nonoperated patients, the most favorable quality of life was experienced by those with segmental involvement of the colon or ileum. Poor prognosis correlated with ileocolic disease and presence of sepsis because of an internal fistula.     

Recurrence after surgery in Crohn's disease. Relationship to location of disease (clinical pattern) and surgical indication

Among 615 patients with Crohn's disease originally diagnosed at the Cleveland Clinic Foundation from 1966 to 1969, 592 have been followed (96%) for a mean of 13 yr. Of these, 438 had undergone operation. The purpose of this study was to determine how many of these patients had developed recurrences requiring another operation and to relate recurrences to the original anatomic location of disease (the clinical pattern) and surgical indication. Those patients with ileocolic disease had the highest recurrence: 53% compared with 45% for colonic and 44% for small intestinal patterns. Second recurrences were ileocolic pattern 35%, colon 34%, small intestine 38%. The estimated median time of recurrence was similar among these three groups. The presence of internal fistula or perianal disease as an indicator for surgery were associated with a higher likelihood of recurrence and a shortened estimated median time to recurrence. This study supports the concept of conservatism with regard to the management of these two complications for patients with Crohn's disease.     

Emergency and elective surgery for small bowel Crohn's disease

Advancements in the medical treatment of Crohn's disease have reduced the need for surgery. The indications for surgery include the failure of medical management, especially the persistence or worsening of symptoms in spite of proper treatment and complications of the disease process. These complications include intestinal obstruction, intestinal perforation with fistula formation or abscess, free perforation, gastrointestinal bleeding, urologic complications, cancer, and perianal disease. In these cases, operative therapy should be directed to the specific indication for surgery, resecting only the segment of bowel involved in the complicating process while preserving as much bowel length as possible in order to prevent short-bowel syndrome. Laparoscopic surgery has been gaining acceptance as an alternative surgical approach for properly selected patients with Crohn's disease. In conclusion, identifying the need for surgery and determining the timing of operation are the cornerstones to successful surgical management of patients with Crohn's disease.     

Anatomical involvement and clinical features in 91 Japanese patients with Crohn's disease

Ninety-three patients with Crohn's disease who had not undergone bowel resection at the time of diagnosis (during the years 1969-1983) were selected for the study, to elucidate whether initial anatomical involvement correlates with clinical manifestations, complications, laboratory findings, and prognosis. Forty-one patients had isolated small intestine disease (44%), 37 ileocolic (40%), 13 colonic disease alone (14%), and two rectal or appendix involvement (2%). Statistically significant symptoms were fever and rectal bleeding with colon involvement, and number of liquid or very soft stools in 1 week with ileocolic or colon involvement. Statistically significant complications included intestinal obstruction with ileocolic disease, perianal fistulas, and arthritis with colonic disease. Increases in ESR, C-reactive protein, and white blood cell in patients with colon involvement were among the statistically significant laboratory findings. Gammaglobulin was significantly higher in patients with ileocolic or colon involvement than in those with small intestine disease. Red cell count and hemoglobin were significantly lower in patients with ileocolitis than in patients with small intestine involvement. Crohn's disease activity index (CDAI) was significantly higher in patients with ileocolic or colon involvement than in those with small intestine involvement only. These findings confirm that colonic involvement renders the disease more severe than involvement of the small intestine. Surgery was required for 22 patients (24%) during a 2.8-year follow-up, but the difference among the three groups was not significant.     

Occurrence and outcome after primary treatment of anal fistulae in Crohn's disease.

During the period 1955 to 1974 inclusive, 826 patients developed Crohn's disease and were registered citizens of Stockholm County at the time of definite diagnosis. These patients were followed up and investigated with reference to the occurrence of and outcome after treatment for anal fistulae. These fistulae were recorded in 184 patients (23%). The incidence of anal fistulae increased the further distally the intestinal lesion was located. Healing followed local operation for anal fistula before curative intestinal resection in approximately 60% of the patients with small intestinal and combined ileocolic disease. However, patients with colonic Crohn's disease did not heal after such treatment. When curative intestinal resection was the primary procedure, 47% of the patients healed spontaneously. Small intestinal and combined ileocolic disease was associated with a good prognosis--90% were healed at follow-up, while patients with colonic disease had a poor prognosis. The combination of rectal Crohn's disease and anal fistula invariably led to proctocolectomy.     

Perianal Crohn's disease

PURPOSE: This study relates our experience with local surgical management of perianal Crohn's disease. METHOD: Of 1,735 patients with Crohn's disease seen between 1980 and 1990, records of 66 patients (3.8 percent) with symptomatic perianal Crohn's disease treated by local operations were retrospectively reviewed to study outcome of local surgical intervention. RESULTS: All patients had intestinal disease that was limited to the colon in 32 patients (48 percent), ileocolonic region in 22 patients (33 percent), and ileum in 12 patients (18 percent). Types of perianal disease encountered included perianal suppuration (57), anal fistula (47), anal fissure (21), anal stenosis (5), gluteal abscess (3), scrotal abscess (2), and anovaginal fistula (2). A total of 321 episodes of anal complications necessitated 256 local surgical interventions. Local anorectal operations performed included simple incision and drainage of abscess (57), fistulotomy (35), incision and drainage of complex anorectal abscesses and fistulas and insertion of seton (24), internal sphincterotomy (6), fissurectomy (1), and anal dilation (3). Of 24 patients with horseshoe abscesses and fistulas managed with insertion of a seton and 35 patients who underwent fistulotomy as a primary procedure or in conjunction with drainage of an abscess, none experienced fecal incontinence as a direct result of the operation. Thirteen patients required proctectomy to control perianal disease, and a similar number underwent total proctocolectomy for extensive intestinal disease. Forty patients (61 percent) continue to retain a functional anus. CONCLUSION: Patients with symptomatic low anal fistula involving minimum sphincter musculature can be treated safely with fistulotomy. In treatment of patients with horseshoe abscesses and high fistulas, aggressive local surgical intervention using a seton permits preservation of the sphincter and good postoperative function.Poster presentation at the meeting of the American Gastroenterological Association, Digestive Disease Week, San Diego, California, May 14 to 17, 1995.     

Risk factors for recurrence after bowel resection for Crohn's disease

BACKGROUND Complications of Crohn's disease such as intestinal obstruction, fistula or perforation often need surgical treatment. Nearly 70%-80% patients with Crohn's disease would receive surgical treatment during the lifetime. However, surgical treatment is incurable for Crohn's disease. The challenge of recurrence postoperatively troubles both doctors and patients. Over 50% patients would suffer recurrence postoperatively. Some certain risk factors are associated with recurrence of Crohn's disease.AIM To evaluate the risk factors for endoscopic recurrence and clinical recurrence after bowel resection in Crohn's disease.METHODS Patients diagnosed Crohn's disease and received intestinal resection between April 2007 and December 2013 were included in this study. Data on the general demographic information, preoperative clinical characteristics, surgical information, postoperative clinical characteristics were collected. Continuous data are expressed as median(inter quartile range), and categorical data as frequencies and percentages. Kaplan-Meier method was applied to estimate the impact of the clinical variables above on the cumulative rate of postoperative endoscopic recurrence and clinical recurrence, then log-rank test was applied to test the homogeneity of those clinical variables. Multivariate Cox proportional hazard regression analysis was performed to identify the risk factors of postoperative endoscopic recurrence and clinical recurrence.RESULTS A total of 64 patients were included in this study. The median follow-up time for the patients was 17(9.25-25.75) mo. In this period, 41 patients(64.1%) had endoscopic recurrence or clinical recurrence. Endoscopic recurrence occurred in34(59.6%) patients while clinical recurrence occurred in 28(43.8%) patients, with the interval between the operation and recurrence of 13.0(8.0-24.5) months and 17.0(8.0-27.8) mo, respectively. In univariate analysis, diagnosis at younger age(P 0.001), disease behavior of penetrating(P = 0.044) and preoperative use of anti-tumor necrosis factor(TNF)(P = 0.020) were significantly correlated with endoscopic recurrence, while complication with perianal lesions(P = 0.032) and preoperative use of immunomodulatory(P = 0.031) were significantly correlated with clinical recurrence. As to multivariate analysis, diagnostic age(P = 0.004),disease behavior(P = 0.041) and preoperative use of anti-TNF(P = 0.010) were independent prognostic factors for endoscopic recurrence, while complication with perianal lesions(P = 0.023) was an independent prognostic factor for clinical recurrence.CONCLUSION Diagnostic age, disease behavior, preoperative use of anti-TNF and complication with perianal lesions were independent risk factors for postoperative recurrence in Crohn's disease.     

Enterovesical fistula complicating Crohn's ileocolitis

An enterovesical fistula, an infrequent complication of Crohn's ileocolitis which is considered to constitute a difficult surgical problem, was encountered in 29 patients. These patients had been treated for Crohn's disease by medical means for years and several had previously undergone bowel resections. An exacerbation of the Crohn's disease occurred in all patients coincident with the appearance of dysuria or the obvious clinical presentation (fecaluria) of the fistula. Other manifestations of active Crohn's disease frequently coexisted. Radiographic evaluation was of limited help in establishing the presence of the fistula. Cystoscopy was suggestive of the diagnosis in 18 of 20 patients so examined. Treatment consisted of ileocecal resection with primary anastomosis (25) or exteriorization (4). The bladder defect was sparingly excised and closed with absorbable sutures. One patient developed a bladder leak which closed spontaneously. Recovery was uneventful in the others. An ileovesical fistula constitutes an indication for operation not only to eradicate the urinary sepsis but also to correct the other complications (malnutrition, obstruction, abscess) of Crohn's disease. To assure an uncomplicated course, emphasis must be placed on an individually designed correct approach to the (causative) intestinal problem, while the surgical aspects of the bladder defect can be a matter of routine.     

Surgical treatment for small bowel Crohn's disease: an experience of 28 cases.

BACKGROUND: Crohn's disease is increasingly encountered in India. This paper reviews our experience with surgery for small bowel involvement in Crohn's disease. METHODS: Retrospective analysis of prospectively collected data of patients who underwent surgical resection for Crohn's disease during a period of 8.8 years from 1997-2006 at a tertiary care center. RESULTS: Twenty-eight patients (mean age 31.2 years; 18 men) underwent surgical treatment for Crohn's disease. The diagnosis was made only after surgery in 17 patients; 5 of them were receiving anti-tuberculosis treatment. The most common indication for elective surgery was subacute intestinal obstruction (n=15) followed by enterocutaneous fistula (3) and protein-losing enteropathy (2). Emergency surgery was performed in 4 patients who presented with perforation and peritonitis. Resection of the maximally involved segment and primary anastomosis was done in all elective cases. Resection and exteriorization of resected ends was done in patients who presented with peritonitis. Multiple strictureplasties combined with resection were done in 9 patients. Predominant colonic involvement was observed in 2 patients. The type of small bowel involvement included strictures (n=25), fistulizing disease (8) and perforation (6); 11 patients had more than one pathology. Postoperative morbidity was observed in nine patients; 6 patients underwent re-operation for anastomotic leak. Stoma had to be created in 11 patients either primarily or at re-operation, which could be closed after a median interval of 3.2 months. During a median follow up of 29 months, 3 patients required more than one hospital admission for abdominal symptoms. Pre-operative anemia, malabsorption and/or growth retardation, steroid and/or immunosuppressant therapy and mid small bowel resection had a negative impact on anastomotic integrity leading to anastomotic dehiscence. Indication for surgery, the type or extent of disease did not have any impact on postoperative morbidity. CONCLUSION: This retrospective analysis from a tertiary referral center indicates that sub-acute intestinal obstruction and perforation-peritonitis were the most common indications for surgery in Crohn's disease. Pre-operative anemia, malabsorption state, steroid/immunosuppressant and mid small bowel resection were associated with higher postoperative morbidity.     

Crohn's disease small bowel strictureplasties: early and late results

BACKGROUND: Strictureplasty is an alternative surgical procedure for Crohn's disease, particulary in patients with previous resections or many intestinal stenosis. AIM: To analyze surgical complications and clinical follow-up in patients submitted to strictureplasty secondary to Crohn's disease. METHODS: Twenty-eight patients (57.1% male, mean age 33.3 years, range 16-54 years) with Crohn's disease and intestinal stenosis (small bowel, ileocecal region and ileocolic anastomosis) were submitted to strictureplasty, at one institution, between September 1991 and May 2004. Thirteen patients had previous intestinal resections. The mean follow-up was 58.1 months. A total of 116 strictureplasties were done (94 Heineke-Mikulicz--81%, 15 Finney--13%, seven side-to-side ileocolic strictureplasty--6%). Three patients were submitted to strictureplasty at two different surgical procedures and two in three procedures. RESULTS: Regarding to strictureplasty, postoperative complication rate was 25% and mortality was 3.6%. Early local complication rate was 57.1%, with three suture leaks (10.7%) and late complication was present in two patients, both with incisional hernial and enterocutaneous fistulas (28.6%). Patients remained hospitalized during a medium time of 12.4 days. Clinical and surgical recurrence rates were 63% and 41%, respectively. Among the patients submitted to another surgery, two patients had two more operations and one had three. Recurrence rate at strictureplasty site was observed in 3.5%, being Finney technique the commonest one. Presently, 19 patients had been asymptomatic with the majority of them under medical therapy. CONCLUSION: Strictureplasties have low complication rates, in spite of having been done at compromised site, with long term pain relief. Considering the clinical course of Crohn's disease, with many patients being submitted to intestinal resections, strictureplasties should be considered as an effective surgical treatment to spare long intestinal resections.     

Surgery for Crohn's disease in Greece: a follow-up study of 79 cases

BACKGROUND/AIMS: The aim of this prospective study was to elucidate the clinical features, indications for surgery and long-term outcome of a series of 79 Greek patients operated on for Crohn's disease. METHODOLOGY: The clinical features and follow-up of 79 out of 155 patients with definite diagnosis of Crohn's disease (51%), who were operated on at least once during the course of their disease, are analyzed. Three main locations of the disease were identified (small bowel, large bowel and small and large bowel). The need for surgery, indications for surgery and outcome of patients were analyzed and compared separately for these three main locations. The mean follow-up period after the first operation was 8.8 +/- 6.5 years. RESULTS: The proportion of men to women was 1.55:1 (P = 0.068). The main indication for surgery was poor response to conservative treatment, followed by obstructive ileus, erroneous diagnosis of acute appendicitis and development of fistulae or abscesses. Statistically significant differences between the three main locations of the disease were found for obstructive ileus (P < 0.01), and bowel perforation (P < 0.0297). Enterectomy and end-to-end anastomosis was the most frequently performed operation. Minor surgical procedures were performed mainly for drainage of perianal abscess. Differences in the number of operations required (one, two and three or more) according to the three main locations of the disease were statistically significant (P < 0.044). Emergency operation was required in 17.3%. Most of the urgently operated patients had only small bowel involvement. Twenty-six percent of patients required a surgical procedure for perianal disease. One or more, major or minor, perioperative complications occurred in 13 out of 79 operated patients (16.4%). No perioperative deaths were noticed. Evolution to cancer was observed in 2% (3 patients). The outcome of patients after the operation was characterized by exacerbations and remissions. A mortality rate of 11.6% was noticed in the follow-up period. However, most deaths were unrelated to the underlying Crohn's disease. CONCLUSIONS: The clinicoepidemiological characteristics of patients with Crohn's disease of Greek origin operated-on for their disease do not differ significantly from those reported from other Western or neighboring Mediterranean countries. However, other parameters such as the relatively low incidence of overall surgical need, the low incidence of colorectal cancer and the low incidence of surgery for perianal disease, all underline the importance of various genetic and environmental factors on the evolution and behavior of the disease in different parts of the world.     

Use of endoscopic ultrasound to guide combination medical and surgical therapy for patients with Crohn's perianal fistulas

BACKGROUND: This study was performed to assess if using endoscopic ultrasound (EUS) to assess and guide combination medical and surgical therapy during fistula healing will lead to a high rate of durable fistula closure and a low or absent incidence of perianal abscess formation in patients with Crohn's perianal fistulas. METHODS: This is a retrospective analysis of 21 patients who presented with a symptomatic Crohn's perianal fistula. Patients were enrolled in a clinical practice protocol of serial EUS exams. All patients underwent a baseline rectal EUS and were placed on maximal medical treatment with 6-mercaptopurine (6-MP) or azathioprine, Cipro, and infliximab (5 mg/kg at 0, 2, and 6 wk and then every 8 wk). Patients were also assessed at baseline by a colorectal surgeon who was aware of the EUS findings. Seton placement and incision and drainage were performed when appropriate. Serial EUS examinations were performed, and the findings were used to guide therapy (i.e., the presence of fistula healing on EUS was used to guide seton removal, discontinuation of infliximab, and Cipro). RESULTS: In the 21 patients enrolled, the median duration of active perianal symptoms was 9 wks (1-36). 10 patients (48%) had previous perianal surgery and 5 (24%) had received infliximab previously. The fistulas treated included 8 trans-sphincteric, 2 superficial, 3 recto-vaginal, and 7 with multiple and horseshoe fistulas. 13 patients (62%) had associated abscesses at presentation. Eighteen of 21 patients (86%) had complete cessation of drainage initially. Median time to cessation of drainage was 10.6 weeks (range, 4-32 wk). Sixteen of 21 patients (76%) maintained long-term cessation of drainage. The median length of follow-up was 68 weeks (range, 35-101 wk). No abscess developed during treatment in any patient. EUS evidence of persistent fistula activity was seen in 10 patients (48%). Of the 11 patients (52%) in whom EUS showed no persistent fistula activity, 7 (64%) have maintained fistula closure off of infliximab and Cipro. Median duration from last infliximab infusion was 47 weeks (range, 20-80 wk). The remaining 4 patients continued infliximab to maintain remission of their luminal disease. Only 1 patient with a horseshoe fistula showed complete healing on EUS. CONCLUSION: In conclusion, using EUS to guide therapy for Crohn's perianal fistulas with infliximab, an immunosuppressive, and an antibiotic is associated with a high short and long-term fistula response rate. EUS may identify a subset of patients who can discontinue infliximab without recurrence of fistula drainage.     

Colonic Crohn's disease

The present review deals with the elective and emergency management of colonic Crohn's disease (CD). Failed medical therapy is among the most common indications for the operative treatment. In case of fistula the operation is usually a resection of the diseased segment of colon with wedge or segmental excision and closure of the secondarily involved organ. The incidence of Crohn's colonic stricture ranges from 5% to 17%. The main indication for performing a total colectomy and ileoproctostomy in patients with extensive Crohn's colitis is to avoid a permanent ileostomy and preserve rectal function. The authors performed 60 laparoscopic procedures: 35 ileocolic resections, 10 total colectomies, 10 loop ileosigmoidectomies, and 1 proctectomy. In conclusion, the choice of operation depends on many factors, such as the site and extent of disease. In some select instances a segmental resection of CD may afford better function than an ileoproctostomy. Received: 21 June 1999 / Accepted in revised form: 8 March 2000     

Management of perianal Crohn's disease

PURPOSE: Management of perianal Crohn's disease is still controversial, and reports on large series are very few in the literature. The aim of this multicenter study was to investigate the outcome of both medical and surgical treatment in 225 patients. METHODS: Patients cared for at different institutions were followed up for a median of six years. Most of them had either anal fistula or an abscess (86 percent and 43 percent, respectively), but fissures were also present in 26 percent of the cases. Diarrhea and anal pain were the most common symptoms. Anal lesions preceded the onset of intestinal symptoms in 19 percent of cases. RESULTS: Medical treatment was curative only in 21 of 123 patients. Overall, medical and surgical treatment either cured or improved 62 percent of the cases. Fifty percent had an intestinal resection. Abscess drainage and fistulotomy were the most common anal surgeries. Rectovaginal fistulas (n=30) required intestinal surgery in 36 percent and anal surgery in 20 percent of the cases, 50 percent with good results. Of 166 patients who had anal surgery, 97 (58 percent) had a positive outcome. Recurrence of anal disease requiring further surgery occurred in 24.5 percent of the cases. CONCLUSIONS: Limited surgeries seem to achieve satisfactory results in more than one-half of the patients affected by perianal Crohn's lesions, whereas medical treatment alone is curative in a small portion of them.Read at the Falk Symposium, Estoril, Portugal, May 6 to 8, 1994.     

Factors influencing postoperative recurrence of Crohn's disease in childhood.

We have reviewed the outcome of all patients undergoing their first intestinal resection for Crohn's disease at this hospital between 1970 and 1987. Recurrence rates, defined by recurrent intestinal symptoms and radiological confirmation of mucosal disease, were calculated using survival analysis. Age, sex, anatomical location of disease, indication for surgery, preoperative duration of symptomatic disease, use of preoperative bowel rest, and pathological features of the resected bowel were analysed individually and jointly as potential risk factors influencing postoperative recurrence of disease. Eighty two patients (age, mean (SD) 14.8 (2.5) years) underwent intestinal resection and were followed postoperatively for a minimum of one year (mean 5.3 (3.3) years). Anatomical location of disease, indication for surgery, and preoperative duration of symptomatic disease were the only factors that significantly influenced the duration of the recurrence free interval. Patients with diffuse ileocolonic inflammation experienced earlier recurrence (50% at one year) than children with predominantly small bowel disease (50% recurrence at five years, p less than 0.0001). Failure of medical therapy independent of disease location as the sole indication for surgery was associated with an earlier relapse than when surgery was performed for a specific intestinal complication such as abscess or obstruction (p less than 0.003). Patients undergoing resection within one year of onset of symptoms experienced delayed recrudescence of active disease (30% recurrence by eight years) compared with patients whose preoperative duration of symptomatic disease was longer (50% recurrence by four years when preoperative duration of disease was one to four years and 50% by three years when disease had been present greater than four years preoperatively, p = 0.03). The mean height velocity of patients with growth potential increased from 2.4 (2.3) cm per year preoperatively to 8.1 (3.4) cm per year in the first postoperative year (p=0.0001). These results support an early approach to surgery in the management of ileal Crohn's disease with or without caecal or right colonic involvement, especially when complicated by persistent growth failure. The higher recurrence rates in more diffuse ileocolonic disease emphasise the need for alternative treatment strategies in these children.     

Surgical management of entero and colocutaneous fistulae in Crohn's disease: 17 year's experience

BACKGROUND AND AIMS: Fistulous disease is common in Crohn's disease, and entero- and colocutaneous fistulae are particularly debilitating and difficult to manage. We present the results of surgical management of these fistulas. PATIENTS AND METHODS: Retrospective chart review of all 51 patients with Crohn's disease (56 surgical procedures) undergoing surgery for cutaneous fistulae between 1983 and 2000. RESULTS: Previous surgery for Crohn's disease had been carried out in 43 patients (84%). The fistula site was enterocutaneous in 36 patients (64%), colocutaneous in 12 (21%), and anastomotic in 8 (14%); 9 patients (16%) also had associated enteroenteric fistulas. The onset of the fistula followed abscess drainage in 15 (27%) and occurred at the site of recurrent disease in 41 (73%). Forty patients (71%) initially underwent conservative management prior to surgery; 16 (28%) underwent surgery directly. Surgical procedures were: 25 ileocolic resections, 8 stoma revisions with resection, 8 small bowel resections 7 subtotal colectomies, 4 partial colectomies, 3 proctocolectomies, and one fistula tract excision. Mean total length of stay was 18 days (postoperative 10.7 days). Six (11%) patients had eight postoperative complications. Mean follow-up was 48.6 months (range 3-187). Recurrence as defined by either clinical examination or reoperation was documented in nine fistulas (16%), with a mean time to recurrence of 27 months. CONCLUSION: Entero-and colocutaneous fistulae usually occur from a site of active disease. Surgical management with bowel resection, including the fistula, is the preferred method of treatment. Morbidity has been low and recurrence rate lower than expected.     

Pediatric jejunoileitis: a severe Crohn's disease phenotype that requires intensive nutritional management

BACKGROUND: Jejunoileitis (JI) is an unusual manifestation of Crohn's disease (CD) that has been associated with high morbidity and the frequent need for surgical intervention. Although the disease has been well-described in adults, the true prevalence and clinical phenotype in children is unknown. AIM: To compare the clinical course and nutritional impact of CD in children with and without proximal small bowel involvement. METHODS: Patients with either Crohn's jejunitis or JI with or without colonic involvement were identified through a clinical database (1996--2002). All radiologic studies were reviewed by an experienced radiologist blinded to the clinical diagnosis. Thirty-six patients with CD without histologic or radiologic signs of proximal small bowel involvement were used for comparison. All medical, surgical, and hematologic parameters were compared in both disease groups. RESULTS: Among the 134 patients with CD, 23 (17%) had radiologic signs of JI, including intestinal fold thickening (57%), luminal narrowing (31%), and skip lesions (13%). Enteric fistula (6%) and strictures (6%) were less common. Patients with JI were likely to be stunted at the time of diagnosis, require surgical intervention (P < 0.03) and nutritional therapy in the form of nasogastric tube feeds (P < 0.03). Nutritional therapy was also associated with an improvement in height in patients with proximal small bowel disease (OR:5.87). DISCUSSION: JI is a relatively common disease phenotype in children with CD that requires aggressive nutritional and surgical intervention. Future studies are required to determine if the early detection and use of immune modulators may lessen the morbidity associated with proximal small bowel disease.     

Surgical treatment of enterovesical fistulas in Crohn's disease

A review of the surgical treatment of enterovesical fistula in Crohn's disease was undertaken to evaluate its effectiveness and long-term results. Sixty-three patients, 39 men and 24 women, with a mean age of 34.4 years were identified with enterovesical fistula. They had documented Crohn's disease for a mean period of 7.0 years. Distribution of anatomic pattern was 34.9 percent ileal, 7.9 percent colonic, and 57.2 percent ileocolic. Nineteen (30.1 percent) had previous abdominal surgery for Crohn's disease. Presenting symptoms included frequency and dysuria in 93.6 percent, pneumaturia in 79.3 percent, and fecaluria in 63.4 percent; 60.3 percent of patients had all three features. Enterovesical fistula was confirmed preoperatively in 43 patients, suspected clinically in 15 patients, and diagnosed intraoperatively in 5 patients. Sixty-one of 63 patients underwent surgery with resection of the phlegmon or abscess with the diseased bowel and curettage or resection of the fistula. After curettage of the bladder defect, pelvic and bladder drainage was instituted. Coexistent fistulas, most commonly ileosigmoid, occurred in 31 patients. Intra-abdominal abscesses were found in 21 patients, of whom 15 required two-stage procedures. One patient died (mortality 1.6 percent), urine leak occurred in 3.2 percent, and wound infection occurred in 1.6 percent. Follow-up (mean, 106 months) has identified one recurrence of enterovesical fistula due to Crohn's disease, and a further recurrence from concomitant sigmoid diverticulitis. Enterocutaneous fistulas developed in 6.4 percent and 11 patients (17.4 percent) have required further resections for Crohn's disease. Surgical treatment of enterovesical fistula in Crohn's disease is a safe and effective treatment.Study performed at The Cleveland Clinic Foundation.Read at the meeting of The American Society of Colon and Rectal Surgeons, Toronto, Canada, June 11 to 16, 1989.     

Infliximab treatment and prognostic factors for response in patients with Crohn's disease.

OBJECTIVE: The aim of this study is to report our experience with infliximab and analyse prognostic factors for response in Crohn's disease (CD). MATERIAL AND METHODS: Consecutive patients were prospectively enrolled in the study when referred for infliximab infusion. Data collected included indication for infusion, patient epidemiological characteristics, Vienna classification, previous surgery, previous medications and extra-intestinal manifestations. Adverse events and clinical response were tabulated separately for patients with luminal or fistulous Crohn's disease. RESULTS: 28 patients were treated (7 with inflammatory and 21 with fistulizing disease). Patients received a total of 116 infusions of infliximab: 57.1% (4 of 7) of patients with luminal disease had complete response within a median of 17.5 days (range 15-28 days), and 62% (13 of 21) of patients with fistulizing disease had complete response within a median of 9 days (range 6-51 days). All patients (5) without relapse received concomitant treatment with immune modifiers. The group of patients with previous resection or perianal fistula repair had complete response more frequently p = 0.03 (OR = 30; IC 95% = 1.47-119.8). CONCLUSIONS: Infliximab is safe and beneficial in clinical practice for Crohn's disease. The re-treatment regimen of infliximab is effective in maintaining clinical response. Immunosuppressant therapy may have a role in the duration of maintained clinical remission in patients with fistulizing disease. In patients with perianal fistulizing disease infliximab treatment is more effective when previous resection or fistula repair is present.     

Does Infliximab Infusion Impact Results of Operative Treatment for Crohn’s Perianal Fistulas?

PURPOSE: Infliximab is an effective treatment for active intestinal Crohn's disease; however, the efficacy of infliximab in perianal Crohn's disease is controversial. This study was designed to compare patients with Crohn's disease who underwent perianal fistula surgery with or without infliximab infusion. METHODS: A retrospective chart review of 226 consecutive patients with Crohn's disease who underwent operative treatment with or without infliximab (3-6 infusions of 5 mg/kg) from March 1991 through December 2005 was completed. Patients were classified as completely healed, minimally symptomatic (seton placement with minimal drainage and/or infliximab dependence), and failure (persistent or recurrent symptomatic fistula, diverting procedure, or proctectomy). RESULTS: A total of 226 patients underwent operative treatment alone (n = 147) or in combination with infliximab infusion (n = 79). Age, gender, and preoperative history of intestinal and perianal Crohn's disease were similar between groups. Mean follow-up was 30 (range, 6-216) months. Operative treatment consisted of seton drainage (n = 112), conventional fistulotomy (n = 92), fibrin glue injection (n = 14), advancement flap (n = 5), collagen plug insertion (n = 2), and transperineal repair (n = 1). Eighty-eight patients (60 percent) healed completely with operative treatment alone, and 47 patients (59 percent) healed after operative treatment in combination with infliximab (P = not significant). CONCLUSIONS: Operative treatment of perianal fistulas in patients with Crohn's disease resulted in complete healing in approximately 60 percent of patients. Preoperative infliximab infusion did not affect overall healing rates.
