Recurrence and reoperation after strictureplasty for obstructive Crohn's disease: long-term results [corrected]

Surgical and non-surgical risk factors affecting the insufficiency of ileocolic anastomosis after first-time surgery in Crohn’s disease patients

BACKGROUND

Crohn's disease (CD) often necessitates surgical intervention, particularly when it manifests in the terminal ileum and ileocecal valve. Despite undergoing radical surgery, a subset of patients experiences recurrent inflammation at the anastomotic site, necessitating further medical attention.

AIM

To investigate the risk factors associated with anastomotic insufficiency following ileocecal resection in CD patients.

METHODS

This study enrolled 77 patients who underwent open ileocolic resection with primary stapled anastomosis. Patients were stratified into two groups: Group I comprised individuals without anastomotic insufficiency, while Group II included patients exhibiting advanced anastomotic destruction observed endoscopically or those requiring additional surgery during the follow-up period. Surgical and non-surgical factors potentially influencing anastomotic failure were evaluated in both cohorts.

RESULTS

Anastomotic insufficiency was detected in 12 patients (15.6%), with a mean time interval of 30 months between the initial surgery and recurrence. The predominant reasons for re-intervention included stenosis and excessive perianastomotic lesions. Factors associated with a heightened risk of anastomotic failure encompassed prolonged postoperative obstruction, anastomotic bleeding, and clinically confirmed micro-leakage. Additionally, patients in Group II exhibited preoperative malnutrition and early recurrence of symptoms related to CD.

CONCLUSION

Successful surgical outcomes hinge on the attainment of a fully functional anastomosis, optimal metabolic status, and clinical remission of the underlying disease. Vigilant endoscopic surveillance following primary resection facilitates the timely identification of anastomotic failure, thereby enabling noninvasive interventions.

Crohn disease: before and after 1932 year

The article describes the historical milestones in the study of Crohn's disease from the time of its original description in the 17th century, the revolution in the medical community after the landmark paper in 1932, to the present day. The history of Crohn's disease testifies to the discoveries of the past years, which open up to us the advantages of a scientific approach to the diagnosis and treatment of this disease.

The Predictive Value of Inflammation at Ileocecal Resection Margins for Postoperative Crohn's Recurrence: A Cohort Study

BACKGROUND

Resections for Crohn's disease should be limited and only resect macroscopically affected bowel. However, recent studies suggest microscopic inflammation at resection margins as a predictor for postoperative recurrence. The clinical impact remains unclear, as non-uniform pathological criteria have been used. The aim of this study was to assess the predictive value of pathological characteristics at ileocecal resection margins for recurrence.

METHODS

Both resection margins of 106 consecutive patients undergoing ileocecal resection for Crohn's disease between 2002 and 2009 were revised and scored for active inflammation, myenteric plexitis, and granulomas. Pathological findings were correlated to recurrence, defined as recurrent disease activity demonstrated by endoscopy (modified Rutgeerts score ≥i2) requiring upscaling medical treatment, using multivariate analysis.

RESULTS

Active inflammation was found at the proximal and distal resection margin in 27% and 15% of patients, respectively, myenteric plexitis in 37% and 32%, respectively, and granulomas in 4% and 6%, respectively. In total, 47 out of 106 patients developed recurrence. Only active inflammation at the distal colonic resection margin was an independent significant predictor for recurrence (88% vs 43% vs 51% for distal, proximal, and no involved margins, respectively; P < 0.01).

CONCLUSION

Active inflammation at the distal colonic resection margin after ileocecal resection identifies a patient group at high risk for postoperative recurrence both at the anastomotic site and the colon because it identifies undiagnosed L3 disease. These patients have a different and more aggressive natural history and require more intense medical treatment. Therefore, pathological evaluation of the distal resection margin should be implemented in daily practice.

Short- and long-term outcomes of strictureplasty for obstructive Crohn's disease

AIM

To evaluate the frequency and outcome of strictureplasty in the era of biologicals and to compare patients operated on by strictureplasty alone, resection alone or a combination of both.

METHOD

A retrospective review of all patients undergoing strictureplasty for obstructing jejunoileal Crohn's disease (CD) in Oxford between 2004 and 2016 was conducted. For comparison, a cohort of CD patients with resection only during 2009 and 2010 was included.

RESULTS

In all, 225 strictureplasties were performed during 85 operations, 37 of them in isolation and 48 with simultaneous resection. Another 82 procedures involved resection only; these patients had shorter disease duration, fewer previous operations and longer bowel preoperatively. The frequency of strictureplasty procedures did not alter during the study period and was similar to that in the preceding 25 years. There was no postoperative mortality. One patient required re-laparotomy for a leak after strictureplasty. None developed cancer. The 5-year reoperation rate for recurrent obstruction was 22% (95% CI 12-39) for resection alone, 30% (17-52) for strictureplasty alone and 42% (27-61) for strictureplasty and resection (log rank P = 0.038). Young age was a risk factor for surgical recurrence (log rank P = 0.006).

CONCLUSION

The use of strictureplasty in CD has not changed significantly since the widespread introduction of biologicals. Surgical morbidity remains low. The risk of recurrent strictures is high and young age is a risk factor. In this study, strictureplasty alone was associated with a lower rate of reoperation compared with strictureplasty with resection.

Analysis of the Risk Factors of Surgery after Endoscopic Balloon Dilation for Small Intestinal Strictures in Crohn's Disease Using Double-balloon Endoscopy

Objective Balloon-assisted endoscopy enables access to and treatment of strictures in the small intestine using endoscopic balloon dilation (EBD); however, the long-term outcomes of EBD have not been sufficiently evaluated. This study evaluated the long-term outcomes of EBD in Crohn's disease to identify the risk factors associated with the need for subsequent surgical intervention. Methods We retrospectively analyzed patients with Crohn's disease who had undergone EBD with double-balloon endoscopy (DBE) for small intestinal strictures at a single center between 2006 and 2015. The long-term outcomes were assessed based on the cumulative surgery-free rate following initial EBD. Results Seventy-two EBD with DBE sessions and 112 procedures were performed for 37 patients during this period. Eighteen patients (48.6%) required surgery during follow-up. Significant factors associated with the need for surgery in a multivariate analysis were multiple strictures (adjusted hazard ratio, 14.94; 95% confidence interval, 1.91-117.12; p=0.010). One patient (6.7%) required surgery among 15 who had single strictures compared to 17 (77.3%) among 22 patients with multiple strictures. Conclusion In a multivariate analysis, the presence of multiple strictures was a significant risk factor associated with the need for surgery; therefore, a single stricture might be a good indication for EBD using DBE for small intestinal strictures in Crohn's disease patients.

Endoscopy in the Diagnosis and Management of Complications of Inflammatory Bowel Disease

The role of endoscopy in inflammatory bowel disease (IBD) has grown over the last decade in both diagnostic and therapeutic realms. It aids in the initial diagnosis of the disease and also in the assessment of the extent and severity of disease. IBD is associated with development of multiple complications such as strictures, fistulae, and colon cancers. Endoscopy plays a pivotal role in the diagnosis of colon cancer in patients with IBD through incorporation of chromoendoscopy for surveillance. In addition, endoscopic resection with surveillance is recommended in the management of polypoid dysplastic lesions without flat dysplasia. IBD-associated benign strictures with obstructive symptoms amenable to endoscopic intervention can be managed with endoscopic balloon dilation both in the colon and small intestine. In addition, endoscopy plays a major role in assessing the neoterminal ileum after surgery to risk-stratify patients after ileocolonic resection and assessment of a patient with ileoanal pouch anastomosis surgery and management of postsurgical complications. Our article summarizes the current evidence in the role of endoscopy in the diagnosis and management of complications of IBD.

Therapeutic Armamentarium for Stricturing Crohn's Disease: Medical Versus Endoscopic Versus Surgical Approaches

One-third of patients with Crohn's disease (CD) present as stricturing phenotype characterized by progressive luminal narrowing and obstructive symptoms. The diagnosis and management of these patients have been intriguing and challenging. Immunomodulators and biologics have been successfully used in treating inflammatory and fistulizing CD. There are issues of efficacy and safety of biological agents in treating strictures in CD. Rapid mucosal healing from potent biological agents may predispose patients to the development of new strictures or worsening of existing strictures. On the other hand, strictures constitute one-fifth of the reasons for surgery in patients with CD. Disease recurrence is common at or proximal to the anastomotic site with the majority of these patients developing new endoscopic lesions within 1 year of surgery. The progressive nature of the disease with repetitive cycle of inflammation and stricture formation results in repeated surgery, with a risk of small bowel syndrome. There is considerable quest for bowel conserving endoscopic and surgical strategies. Endoscopic balloon dilation and stricturoplasty have emerged as valid alternatives to resection. Endoscopic balloon dilation has been shown to be feasible, safe, and effective for the short primary or anastomotic strictures. However, repeated dilations are often needed, and long-term outcomes of endoscopic balloon dilation remain to be investigated. The introduction of stricturoplasty has added another dimension to bowel saving strategy. Although postoperative recurrence rate after stricturoplasty is comparable with surgical resection, there are concerns for increased risk of malignancy in preserved bowel. Laparoscopic surgery has widely been performed with similar outcomes to open approach with fewer complications, quicker recovery, better cosmesis, and lower cost. All of these issues should be considered by physicians involved in the management of patients with stricturing CD.

Three-dimensional geometry of the Heineke-Mikulicz strictureplasty

BACKGROUND

The objective of this study was to assess the regional geometry of the Heineke-Mikulicz (HM) strictureplasty. The HM intestinal strictureplasty is commonly performed for the treatment of stricturing Crohn's disease of the small intestine. This procedure shifts relatively normal proximal and distal tissue to the point of narrowing and thus increases the luminal diameter. The overall effect on the regional geometry of the HM strictureplasty, however, has not been previously described in detail.

METHODS

HM strictureplasties were created in latex tubing and cast with an epoxy resin. The resultant casts of the lumens were then imaged using computed tomography. Using 3-dimensional vascular reconstruction software, the cross-sectional areas were determined and the surface geometry was examined.

RESULTS

The HM strictureplasty, while increasing the lumen at the point of the stricture, also results in a counterproductive luminal narrowing proximal and distal to the strictureplasty. Within the model used, cross-sectional area was diminished 25% to 50% below baseline. This effect is enhanced when 2 strictureplasties are placed in close proximity to each other.

CONCLUSIONS

The HM strictureplasty results in alterations in the regional geometry that may result in a compromise of the lumen proximal and distal to the location of the strictureplasty. When 2 HM strictureplasties are created in close proximity to each other, care should be undertaken to assure that the lumen of the intervening segment is adequate.

Short and long-term outcomes of endoscopic balloon dilatation for Crohn’s disease strictures

AIM: To investigate the short and long-term outcomes of endoscopic balloon dilatation (EBD) for Crohn’s disease (CD) strictures.

METHODS: Between January 1995 and December 2011, 47 EBD procedures were performed in 30 patients (8 females and 22 males) with CD. All patients had strictures through which an endoscope could not pass, and symptoms of these strictures included abdominal pain, abdominal fullness, nausea, and/or vomiting. The 47 strictures included 17 anastomotic and 30 de novo strictures. Endoscopy and dilatation were performed under conscious sedation with intravenous diazepam or flunitrazepam. The dilatations were all performed using through-the-scope balloons with diameters from 8 mm to 20 mm on inflation and lengths of 30-80 mm. Each dilatation session consisted of two to four, 3-min multistep inflations of the balloon, repeated at intervals of 1 wk until adequate dilatation (up to 15-20 mm in diameter) was achieved. The follow-up data were collected from medical records and analyzed retrospectively. Primary success was defined as passage of the scope through the stricture after EBD. Long-term outcomes were analyzed focusing on intervention-free survival and surgery-free survival demonstrated by the Kaplan-Meier method. (Intervention-free meant cases in which neither endoscopic balloon re-dilatation nor surgery was needed after the first dilatation during the observation period). The log rank test was used to evaluate the difference in long-term outcomes between anastomotic and de novo stricture cases.

RESULTS: Primary success was achieved in 44 of the 47 strictures (93.6%). Balloon dilatations failed in 3 cases (6.4%). In 1 case, EBD was a technical failure because the guide-wire could not be passed through the stricture which showed severe adhesion and was a flexural lesion of the intestine. In 2 cases, unexpected perforations occurred immediately after balloon dilatation. Of the 47 treatments, complications occurred in 5 (10.6%). All 5 patients had de novo strictures. One suffered bleeding, two high fever and there were colorectal perforations. One of the patients with a colorectal perforation was treated surgically, the other was managed conservatively. These 2 cases correspond to the two aforementioned EBD failures. Long-term outcomes were evaluated for the 44 successfully-treated strictures after a median follow-up of 26 mo (range, 2-172 mo). During the observation period, re-strictures after EBDs occurred in 26 cases (60.5%). Fourteen of these 26 re-stricture cases underwent EBD again, but in two EBD failed and surgery was ultimately performed in both cases. Twelve of the 26 re-stricture cases were initially treated surgically when the re-strictures occurred. Finally, 30 of the 47 strictures (63.8%) were successfully managed with EBD, allowing surgery to be avoided. Intervention-free survival evaluated by the Kaplan-Meier method was 75% at 12 mo, 58% at 24 mo, and 43% at 36 mo. There was no significant difference between the anastomotic strictures (n = 16) and de novo strictures (n = 28) in the intervention-free survival as evaluated by the log-rank test. Surgery-free survival evaluated by the Kaplan-Meier method was 90% at 12 mo, 75% at 24 mo, and 53% at 36 mo. The 16 anastomotic strictures were associated with significantly better surgery-free survivals than the 28 de novo strictures (log-rank test: P < 0.05).

CONCLUSION: Anastomotic strictures were associated with better long-term outcomes than de novo strictures, indicating that stricture type might be useful for predicting the long-term outcomes of EBD.

How I do it: Side-to-side isoperistaltic strictureplasty for extensive Crohn's disease

INTRODUCTION

Bowel-sparing surgical techniques, such as the Heineke-Mikulicz and the Finney strictureplasty, have been proposed as an alternative to lengthy intestinal resection in the treatment of small bowel strictures in Crohn's disease. However, these conventional strictureplasty techniques lend themselves poorly to cases of multiple short strictures closely clustered over a lengthy small bowel segment.

DISCUSSION

In this article, we present the surgical technique of the side-to-side isoperistaltic strictureplasty, which is optimal in addressing these specific situations.

Postoperative recurrent luminal Crohn's disease: a systematic review

Despite improved immunosuppressive therapy, surgical resection is still often required for uncontrolled inflammatory disease and the stenosing and perforating complications of Crohn's disease. However, surgery is not curative. A majority of patients develop disease recurrence at or above the anastomosis. Subclinical endoscopically identifiable recurrence precedes the development of clinical symptoms; identification and treatment of early mucosal recurrence may therefore prevent clinical recurrence. Therapy to achieve mucosal healing should now be the focus of postoperative therapy. A number of clinical risk factors for the development of earlier postoperative recurrence have been identified, and reasonable evidence is now available regarding the efficacy of drug therapies in preventing recurrence. This evidence now needs to be incorporated into prospective treatment strategies.

Intralesional steroid injection after endoscopic balloon dilation in pediatric Crohn's disease with stricture: a prospective, randomized, double-blind, controlled trial

BACKGROUND

Endoscopic balloon dilation (EBD) is an attractive conservative therapy for Crohn's disease (CD) with stricture; however, its long-term efficacy has been questioned because many patients require more dilations or postdilation surgery. Most reports are retrospective, and no pediatric data are available.

OBJECTIVE

To assess the effectiveness of corticosteroid intralesional injection after EBD in preventing stricture recurrence.

DESIGN

Single-center prospective, randomized, double-blind, controlled trial.

SETTING

Tertiary-referral university hospital.

PATIENTS

Between November 2005 and January 2009, 29 pediatric patients with stricturing CD were enrolled.

INTERVENTIONS

Enrolled patients were randomized to receive intrastricture injection of corticosteroid (CS) (n = 15) or placebo (n = 14) after EBD. Patients were followed clinically via small intestine contrast US and intestinal magnetic resonance imaging at 1, 3, 6, and 12 months; all underwent colonoscopy 12 months after dilation.

MAIN OUTCOME MEASUREMENTS

Time free of repeat dilation and time free of surgery in the 2 groups.

RESULTS

One of the 15 patients receiving CS required redilation, whereas the latter was needed in 5 of the 14 placebo patients; surgery was needed in 4 of the placebo patients, but in none of those receiving CS. The 2 groups statistically differed in the time free of redilation (P = .04) as well as for time free of surgery after EBD (P = .02), which were worse in the placebo group compared with the CS group. There were no significant differences in baseline demographics between the 2 groups.

LIMITATIONS

Sample size, participation bias, and short-term follow-up.

CONCLUSION

In pediatric CD with stricture, intralesional CS injection after EBD is an effective strategy for reducing the need both for redilation and surgery.

Comparison of strictureplasty and endoscopic balloon dilatation for stricturing Crohn's disease--review of the literature

BACKGROUND

Stricturing Crohn's disease is accompanied by a high-risk for bowel resection and subsequent short bowel syndrome. Strictureplasty (SP) and endoscopic balloon dilatation (EBD) have been developed to prevent, or at least delay, the requirement for resection. The goal of this study was to compare the outcome of these two procedures with regard to complications and disease recurrence.

METHODS

We conducted a MEDLINE literature search to give a current overview about the safety and efficacy of EBD and SP.

RESULTS

The initial search yielded 744 articles. Case reports, reviews and meta-analyses were excluded. Finally, 63 articles (SP, 40 articles; EBD, 23 articles) were used for the review. None of the studies compared the two methods directly. A total of 2,532 patients (SP, n = 1,958; EBD, n = 574) were included. The incidence of perioperative complications after SP was 11% and the incidence of major complications was 5%. The median surgical recurrence rate was 24% after a median follow-up of 46 months. The median technical success for EBD was 90%. Major complications occurred in 3% of the cases. According to an intention-to-treat protocol, the median surgical recurrence rate was 27.6%. Per-protocol analysis revealed a median surgical recurrence rate of 21.4% after a median follow-up of 21 months.

CONCLUSION

Due to the lack of comparable data, there is currently no reliable information on whether one treatment option is superior to the other. Regarding the limited applicability of EBD in strictures of the small bowel, only a controlled trial would provide evidence as a basis for clinical decision making in CD strictures that are potentially treatable by EBD and SP.

The response of Crohn's strictures to endoscopic balloon dilation

BACKGROUND

Endoscopic balloon dilation has been shown to be an alternative to surgery in the treatment of Crohn's symptomatic strictures.

AIM

To analyse the impact of the type of the strictures -de novo or anastomotic - their location and their length on the outcome of endoscopic balloon dilation.

METHODS

Between December 1999 and June 2008, 55 patients underwent 93 balloon dilations for 74 symptomatic strictures. One stricture was located in the duodenum, 39 strictures were in the terminal ileum, 17 at the ileocoecal anastomosis after a preceding resection and 17 in the colon.

RESULTS

Endoscopic treatment was successful in 76% of the patients during an observation period of 44 (1-103) months. Of the patients, 24% required surgery. All patients who underwent surgery had de novo strictures in the terminal ileum. These strictures were significantly longer compared with the ileal strictures that responded to endoscopic treatment [7.5 (1-25) cm vs. 2.5 (1-25) cm; P = 0.006].

CONCLUSIONS

The long-term success of endoscopic balloon dilation depends on the type of the strictures, their location and their length. Failure of endoscopic treatment was observed only in long-segment strictures in the terminal ileum.

Enteroscopy in the diagnosis and management of Crohn disease

Crohn disease is a chronic disorder that can affect any part of the gastrointestinal tract, and is characterized by mucosal and transmural inflammation of the bowel wall. The disease most commonly involves the small bowel. Evaluation of patients with suspected Crohn disease has traditionally involved the use of ileocolonoscopy, push enteroscopy, and barium small bowel radiography. A large proportion of patients with mild small bowel disease or involvement of the mid small bowel can potentially be missed if only these tests are utilized. Enteroscopy is defined as direct visualization of the small bowel using a fiber optic or wireless endoscope. Following recent advances in technology, enteroscopy currently plays a pivotal role not only in the diagnosis of small bowel Crohn disease but also in the management of its complications, such as bleeding and strictures. Enteroscopy may have additional roles in the future, including the objective assessment of mucosal response to therapy, and surveillance for small bowel malignancy. This article focuses on the utility of enteroscopy, and its advantages and limitations in the evaluation and longterm management of Crohn disease.

The multidisciplinary team for management of inflammatory bowel diseases

Crohn's disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases (IBD) characterized by a relapsing clinical pattern that typically affect people during their adult and economically productive lives. Affected patients require clinical follow-up because of periodic disease flare-up and of the risk of long-term complications. Extensive diagnostic procedures, medical and surgical treatments are often needed over a lifetime. The challenge posed by management of IBD is better faced by a multidisciplinary team that includes health care providers with complementary diagnostic or therapeutic skills. The team is expected to provide the best practice to manage IBD by defining a realistic "diagnostic and therapeutic pathway" for the patients to follow based on locally available professional, structural and technological resources. This approach appears to improve quality of care for IBD patients and to be cost-effective.

[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.

Strictureplasty vs resection in small bowel Crohn's disease: an evaluation of short-term outcomes and recurrence

AIM

To compare postoperative adverse events and recurrence following strictureplasty or bowel resection in patients with small bowel Crohn's disease (CD).

METHOD

A literature search was performed to identify studies published between 1980 and 2006 comparing outcomes of CD patients undergoing either strictureplasty or bowel resection. Hazard ratios were calculated from Kaplan-Meier plots of cumulative recurrence data. Quality assessment of the included studies was performed. Random-effect meta-analytical techniques were employed. Sensitivity analysis and assessment of heterogeneity were performed.

RESULTS

Seven studies comprising 688 CD patients (strictureplasty n = 311, 45%; resection with or without strictureplasty n = 377, 55%) were included. Patients undergoing strictureplasty alone had a lower risk of developing postoperative complications than those who underwent resection (OR = 0.60, 95% CI: 0.31-1.16) although this was not statistically significant (P = 0.13). Surgical recurrence after strictureplasty was more likely than after resection (OR = 1.36, 95% CI: 0.96-1.93, P = 0.09). Patients who had a resection had a significantly longer recurrence-free survival than those undergoing strictureplasty alone (HR = 1.08, 95% CI: 1.02-1.15, P = 0.01).

CONCLUSION

Patients with small bowel CD undergoing strictureplasty alone may have fewer postoperative complications than those undergoing a concomitant bowel resection. However, surgical recurrence maybe higher following strictureplasty alone than with a concomitant small bowel resection. Patients may require appropriate preoperative counselling regarding the pros and cons of each operative technique.

Efficacy and safety of endoscopic balloon dilation for Crohn's strictures

PURPOSE

This study was designed to investigate retrospectively the efficacy and safety of endoscopic balloon dilation for intestinal strictures in Crohn's disease.

METHODS

Sixteen patients with 20 strictures were treated. The stricture sites were as follows: at the ileocolonic (n = 6) or ileoileal (n = 1) anastomosis, in the colon (n = 10), ileum (n = 2), and at the ileocecal valve (n = 1). The dilations were performed with through-the-scope balloons, with diameters of 15 to 20 mm on inflation and lengths of 30 to 80 mm.

RESULTS

In 15 of 16 patients, the strictures were successfully dilated and the symptoms caused by the strictures disappeared after the first session. The patients were followed for a median of 38.5 months. Repeat symptomatic stricture formation occurred after a mean of 19.7 months in seven patients. Four patients needed second-round dilation and three patients were treated surgically. Complications occurred in four patients who had primary strictures: bleeding in one, high fever in one, and colorectal perforation in two. One of the patients complicated with colorectal perforation was treated surgically, and the other was treated conservatively. The cumulative nonsurgical rates for the dilation strictures were 93 percent at 12 months and 65 percent at 36 months, respectively. Three patients were treated surgically because of strictures or fistulas that were not related to the procedure of dilation. As a whole, the cumulative nonsurgical rates were 81 percent at 12 months and 46 percent at 36 months. Nine patients (56.3 percent) were able to avoid surgery.

CONCLUSIONS

Using endoscopic balloon dilation, it may be possible to avoid or postpone surgery. Primary strictures seem to have increased risk of perforation.

Strictureplasty for active Crohn's disease

BACKGROUND AND AIMS

Several studies over the last 20 years have confirmed the safety and efficacy of strictureplasty in the treatment of obstructive Crohn's disease. However, almost all of these studies use strictureplasty to treat fibrotic strictures: limited resection being preferred to treat active disease strictures. One study dating from 1986 used strictureplasty to treat purely active disease strictures, with disappointing results. No other similar studies have been published. We investigate the complication and recrudescence rates together with the intervention-free intervals in patients undergoing strictureplasty for active disease strictures.

METHODS

A retrospective review of 14 patients who underwent strictureplasty either in isolation or in combination with limited resection for active small bowel Crohn's disease between 1996 and 2004 was undertaken.

RESULTS

A total of 73 strictureplasties were carried out. There was no operative mortality; however, one patient subsequently died from metastatic small bowel adenocarcinoma arising from existing Crohn's disease. One patient subsequently developed complications directly attributed to strictureplasty and required further surgery. Three patients developed recrudescent disease and required further surgery in the form of either strictureplasty, limited resection or both. All patients undergoing strictureplasty with resection and over 70% of patients undergoing strictureplasty alone were intervention-free at 41 months. With extended follow-up, the same proportion of patients would remain intervention-free at 70 months or longer.

CONCLUSIONS

The use of strictureplasty in active disease strictures is well tolerated and has similar, if not better, recurrence and complication rates when compared with limited resection in patients with similar disease profiles.

Inflammatory bowel disease: the view of the surgeon

Despite advances in medical therapy, surgery is required in approximately 30-40% of patients with ulcerative colitis (UC) and 70-80% of patients with Crohn's disease (CD) at some point during their lifetime. For patients with UC, surgery may be curative, whereas recurrence of CD following surgery is common due to the potentially pan-enteric distribution of the disease. As a result, the indications and surgical management of the disease may be quite different. For UC, the surgeon is involved in the identification of new cases, management of severe disease, recognition of dysplasia and restorative proctocolectomy. Most of the advances in surgery for UC have been in novel techniques relating to the ileal pouch-anal anastomosis, which can now be performed safely for UC with a 10% pouch failure rate long term. For CD, the surgeon is involved in the management of small bowel and ileo-colonic disease, Crohn's colitis and perianal disease. Advances in the surgical management of CD include strictureplasty for extensive small bowel disease, laparoscopic ileo-caecal resection and a combined medical and surgical approach to perianal disease. For both CD and UC close liaison between the gastroenterologist and colorectal surgeon is essential.

Intervention-free Interval following Strictureplasty for Crohn’s Disease

INTRODUCTION

Strictureplasty is now well established as a bowel-sparing alternative for surgical treatment of complicated Crohn's disease. Limited resection is still preferred in patients with uncomplicated disease, as subsequent reoperation rates are low.

METHODS

A retrospective review of 26 patients who underwent surgery for small bowel Crohn's disease between 1996 and 2004 was undertaken. A total of 96 small bowel strictureplasties had been performed; 19 patients had strictureplasties performed in isolation, and the remaining 7 patients underwent strictureplasty with concomitant limited resection.

RESULTS

There was no operative mortality. The median follow-up was 41 months. Four patients developed complications that required further surgery. At 41 months, 73.3% of patients undergoing strictureplasty alone and 79.7% undergoing strictureplasty with concomitant resection were intervention-free. If followed up to 70 months or more, the same proportion of patients would remain intervention-free. Four patients developed further recrudescent disease and required surgery: strictureplasty, limited resection, or both. Of these patients, 25% were intervention-free at 41 months.

CONCLUSIONS

Our results show that strictureplasty alone or with concomitant resection can confer intervention-free periods of 41 months or more in 73.3% of patients, suggesting that strictureplasty can be utilized as an alternative to limited resection in uncomplicated Crohn's disease.

Long-term follow-up of strictureplasty for Crohn's disease

BACKGROUND

Strictureplasty is an effective means of alleviating obstructive Crohn's disease while conserving bowel length. The aim of this study was to establish long-term outcomes of strictureplasty.

METHODS

Between 1978 and 2003, 479 strictureplasties were performed in 100 patients during 159 operations. Information on Crohn's disease, medical therapy, laboratory indices, surgical details, complication rates and outcomes was recorded. The primary endpoint was abdominal reoperation.

RESULTS

Mean follow-up was 85.1 (range 0.2-240.9) months. The overall morbidity rate was 22.6 per cent, with septic complications in 11.3 per cent, obstruction in 4.4 per cent and gastrointestinal haemorrhage in 3.8 per cent. The 30-day mortality rate was 0.6 per cent and the procedure-related series mortality rate 3.0 per cent. Perioperative parenteral nutrition was the only marker for morbidity (P < 0.001). Reoperation rates were 52 per cent at a mean of 40.2 (range 0.2-205.8) months after a first, 56 per cent at 26.1 (range 3.5-63.5) months after a second, 86 per cent at 27.4 (range 1.4-74.5) months after a third, and 62.5 per cent at 25.9 (range 7.3-70.5) months following a fourth strictureplasty procedure. The major risk factor for reoperation was young age (P < 0.001).

CONCLUSION

Long-term follow-up has confirmed the safety of strictureplasty in Crohn's disease. Morbidity is appreciable, although the surgical mortality rate is low. Reoperation rates are comparable following first and repeat strictureplasty procedures.

Hospitalization, surgery, and readmission rates of IBD in Canada: a population-based study

BACKGROUND

We aimed to define the rates of hospitalization and readmission for inflammatory bowel disease in Canada.

METHODS

The data source was Statistics Canada Person Oriented Information Database (1994-2001). The number of stays for a diagnosis of Crohn's disease (CD) or ulcerative colitis (UC) by ICD-9-CM code 555 or 556 was extracted (and assessed when CD or UC was the first diagnosis or was 1 of 16 diagnoses on the patient discharge abstract). Age-, gender-, and disease-specific rates of hospitalization, length of stay, readmission, and surgery were assessed.

RESULTS

The age-adjusted hospitalization rate for CD declined over 1994-2001 from 29.2 to 26.9/100,000 but was stable for UC at 12.6-13.3 per 100,000. In the 7 yr, 39.4% of CD patients (21.3-24.0%/yr) and 33.7% of UC patients (18.5-20.3%/yr) got readmitted at least once. The average length of stay declined from 10.3 (1994-1995) to 9.1 days (2000-2001) (p = 0.029) in CD and in UC declined from 12.2 to 10.1 days (p = 0.054). Of all hospitalizations, major surgery occurred in 48% of CD (44.8-49.8% per yr) and 55% of UC (51.5-59.0% per yr).

CONCLUSIONS

Rates of hospitalization declined slightly for CD over the 7 yr but still remained twice as great as the rates for UC. Approximately 20% of CD and UC subjects got readmitted per year and over 7 yr approximately 35% got readmitted. Major surgery was a more common reason for hospitalization in UC than in CD.

Factors affecting recurrence after surgery for Crohn’s disease

Although in Crohn’s disease post-operative recurrence is common, the determinants of disease recurrence remain speculative. The aim of this study was to examine factors affecting post-operative recurrence of Crohn’s disease. A Medline-based literature review was carried out. The following factors were investigated: age at onset of disease, sex, family history of Crohn’s disease, smoking, duration of Crohn’s disease before surgery, prophylactic medical treatment (corticosteroids, 5-amino salicylic acid [5-ASA] and immunosuppressants), anatomical site of involvement, indication for surgery (perforating or non-perforating disease), length of resected bowel, anast-omotic technique, presence of granuloma in the specimen, involvement of disease at the resection margin, blood transfusions and post-operative complications. Smoking significantly increases the risk of recurrence (risk is approximately twice as high), especially in women and heavy smokers. Quitting smoking reduces the post-operative recurrence rate. A number of studies have shown a higher risk when the duration of the disease before surgery was short. There were, however, different definitions of ‘short’ among the studies. Prophylactic cortic-osteroids therapy is not effective in reducing the post-operative recurrence. A number of randomized controlled trials offered evidence of the efficacy of 5-ASA (mesalazine) in reducing post-operative recurrence. Recently, the thera-peutic efficacy of immunosuppressive drugs (azathioprine and 6-mercaptopurine) in the prevention of post-operative recurrence has been investigated and several studies have reported that these drugs might help prevent the recurrence. Further clinical trials would be necessary to evaluate the prophylactic efficacy of immunosuppressants. Several studies showed a higher recurrence rate in patients with perforating disease than in those with non-perforating disease. However, evidence for differing recurrence rates in perforating and non-perforating diseases is inconclusive. A number of retrospective studies reported that a stapled functional end-to-end anastomosis was associated with a lower recurrence rate compared with other types of anastomosis. However, prospective randomized studies would be necessary to draw a definite conclusion. Many studies found no difference in the recurrence rates between patients with radical resection and non-radical resection. Therefore, minimal surgery including strictureplasty has been justified in the management of Crohn’s disease. In this review, the following factors do not seem to be predictive of post-operative recurrence: age at onset of disease, sex, family history of Crohn’s disease, anatomical site of disease, length of resected bowel, presence of granuloma in the specimen, blood transfusions and post-operative complications. The most significant factor affecting post-operative recurrence of Crohn’s disease is smoking. Smoking significantly increases the risk of recurrence. A short disease duration before surgery seems, albeit to a very minor degree, to be associated with a higher recurrence rate. 5-ASA has been shown with some degree of confidence to lead to a lower recurrence rate. The prophylactic efficacy of immunosuppressive drugs should be assessed in future. A wider anastomotic technique after resection may reduce the post-operative recurrence rate, though this should be investigated with prospective randomized controlled trials.

Crohn's disease--when to operate?

Crohn's disease is a chronic bowel condition, which can present as a number of different clinical and pathological presentations, depending on localization and activity of the inflammatory process. The aethiology of the disease has not been explained. In each case the treatment should be individually tailored depending on the type of the changes. The indications for surgical intervention are continuous bleedings, recurrent ileus, perforation of the intestine, abscesses, fistulas, failure of pharmacological treatment, resistance to steroids and steroid dependence. In case of the mild type of the disease with few symptoms pharmacological treatment is the right choice In case of the mild type of the disease with few symptoms pharmacological treatment is the right choice process. In malign form of Crohn's disease lack of improvement after 7-10 days of intensive treatment is generally accepted indication for surgical treatment. Fulminant form of the disease is still a clear-cut indication for immediate surgical intervention. Decision on surgical intervention is more difficult and controversial when patient presents with series of subileus recurrences subsiding after conservative treatment. Patients with stenotic form of Crohn's disease usually require multiple operations most of which are bowel resections. Patients with stenotic form of Crohn's disease usually require multiple operations most of which are bowel resections therapy. External and internal asymptomatic fistulas should be treated conservatively. The timing of surgical treatment is essential in Crohn's disease however the prevention from recurrences is also fundamental. It is well proved that preventive administration of 5-ASA (especially mesalazine) and metronidazol can reduce the risk of early recurrences after surgery.

Postoperative change of mucosal inflammation at strictureplasty segment in Crohn's disease: cytokine production and endoscopic and histologic findings

PURPOSE

This study was designed to examine postoperative change of mucosal inflammation at strictureplasty segment in Crohn's disease mainly by cytokine measurements.

METHODS

Patients who underwent strictureplasty for Crohn's disease in the terminal ileum were investigated. Mucosal samples at the strictureplasty site were obtained during operation. At 3, 6, and 12 months after operation, biopsy specimens were taken from the strictureplasty site and macroscopically normal ileum at endoscopy. Mucosal cytokine concentrations were measured by enzyme-linked immunosorbent assay.

RESULTS

The mucosal concentrations of proinflammatory cytokines (interleukin-1beta, interleukin-6, interleukin-8, and tumor necrosis factor-alpha) and anti-inflammatory mediator (interleukin-1 receptor antagonist) at the strictureplasty segment greatly increased at the time of operation. Interleukin-1beta, interleukin-1 receptor antagonist, interleukin-6, interleukin-8, and tumor necrosis factor-alpha concentrations at the strictureplasty segment decreased during a 12-month period after operation. Twelve months after operation there was no significant difference in each cytokine concentration between the strictureplasty and macroscopically normal segments. The mucosal interleukin-1 receptor antagonist/interleukin-1beta ratio at the strictureplasty segment increased during a 12-month period after operation. Twelve months after operation there was no significant difference in the ratio between the strictureplasty and macroscopically normal segments. The endoscopic and histologic severities of mucosal inflammation at the strictureplasty site also decreased; however, their findings were not normalized during the study.

CONCLUSIONS

During one year after strictureplasty for Crohn's disease, cytokine production at the strictureplasty segment was decreased to the level of the macroscopically normal ileum and an imbalance between proinflammatory and antiinflammatory cytokines was corrected.

Role of strictureplasty in surgical treatment of Crohn's disease

BACKGROUND

The aim of this study was to review early and late results of strictureplasty for patients affected by Crohn's disease.

METHODS

We reviewed 103 patients with obstructive Crohn's disease undergoing 293 strictureplasties (Heineke-Mikulicz, 235; Finney, 22; Jaboulay, 35; side-to-side isoperistaltic strictureplasty, 1). Mean age at surgery was 31.4 years. Forty-four patients had at least one previous surgery, and synchronous other surgical procedures were performed in 62 patients. For 41 patients with strictureplasty alone, 154 strictureplasties were done. The site and number of strictures treated by strictureplasty were as follows: duodenum (2), small intestine (265), ileocecal region (6), colon (4), recurrence at previous anastomosis (11), and recurrence at previous strictureplasty (5). The mean number of structureplasties per patient was 2.8. Reoperation has been used as the definitive endpoint for recurrence, and the long-term outcome of strictureplasty was examined.

RESULTS

There was no operative mortality. Septic complications related to strictureplasty developed in 4 patients and reoperation was needed in 2 patients (1.9%). Mean duration of follow-up was 80.3 months. For all patients, the 5- and 10-year reoperation rate was 45.0% and 61.9%, respectively. Forty-five patients (43.7%) required further operation for recurrence, of whom 21 patients (20.4%) had recurrence at the site of strictureplasty, which was restricture in 14 patients and perforating disease in 7 patients. Perforating disease for recurrence was more frequent at the site treated by the Finney or Jabouley procedure compared with Heineke-Mikulicz.

CONCLUSIONS

It is considered that, in the long term, strictureplasty is safe and useful for preserving the intestine in the surgical treatment of Crohn's disease if strictures are carefully selected.

Strictureplasty

BACKGROUND

Advances in the use of bowel-sparing surgery for Crohn's disease have led to the development of strictureplasty as an important technique to conserve small bowel length and reduce morbidity associated with malabsorption.

METHODS

A literature review of long-term studies on strictureplasty was undertaken, and evidence of its safety and efficacy was evaluated.

RESULTS

The safety and efficacy of strictureplasty is confirmed in retrospective studies carried out over a period of 5-10 years, particularly when employed in patients at risk of short bowel syndrome, but certain questions regarding bowel function and disease activity after surgery remain unanswered. There is also concern that diseased tissue is left in situ after strictureplasty; this tissue has the potential for malignant transformation in the long term.

CONCLUSION

Strictureplasty has been used in surgery for Crohn's disease for the past 25 years. Studies have proven its efficacy in the treatment of carefully selected patients at risk of malabsorption owing to short bowel syndrome.

Azathioprine and mesalamine for prevention of relapse after conservative surgery for Crohn's disease

BACKGROUND & AIMS

Because the reoperation rate for Crohn's disease is high after resective surgery, use of conservative surgery has increased. Mesalamine was investigated for the prevention of postoperative relapse, with disappointing results. The role of azathioprine in the postoperative setting is unknown. We aimed to compare the efficacy and safety of azathioprine and mesalamine in the prevention of clinical and surgical relapse in patients who have undergone conservative surgery for Crohn's disease.

METHODS

In a prospective, open-label, randomized study, 142 patients received azathioprine (2 mg. kg -1. day -1 ) or mesalamine (3 g/day) for 24 months. Clinical relapse was defined as the presence of symptoms with a Crohn's Disease Activity Index score >200 and surgical relapse as the presence of symptoms refractory to medical treatment or complications requiring surgery.

RESULTS

After 24 months, the risk of clinical relapse was comparable in the azathioprine and mesalamine groups, both on intention-to-treat (odds ratio [OR], 2.04; 95% confidence interval [CI], 0.89-4.67) and per-protocol analyses (OR, 1.79; 95% CI, 0.80-3.97). No difference was observed with respect to surgical relapse at 24 months between the 2 groups. In a subgroup analysis, azathioprine was more effective than mesalamine in preventing clinical relapse in patients with previous intestinal resections (OR, 4.83; 95% CI, 1.47-15.8). More patients receiving azathioprine withdrew from treatment due to adverse events than those receiving mesalamine (22% vs. 8%; P = 0.04).

CONCLUSIONS

While no difference was observed in the efficacy of azathioprine and mesalamine in preventing clinical and surgical relapses after conservative surgery, azathioprine is more effective in those patients who have undergone previous intestinal resection.

Colonoscopic balloon dilation of Crohn's strictures: a review of long-term outcomes

OBJECTIVE

To study the long-term outcomes of patients who have had endoscopic balloon dilation of Crohn's strictures.

DESIGN

Retrospective case-note review over a 16-year period.

PATIENTS

Patients with a Crohn's stricture causing obstructive symptoms and who had at least 6 months' follow-up data or a surgical outcome following dilation were sought; 59 patients (124 dilations) were identified.

INTERVENTION

Patients all underwent endoscopic balloon dilation.

RESULTS

Strictures were anastomotic in 53 patients (111 dilations) and de novo in six patients (13 dilations). The median stricture length was 3.0 cm. Median follow-up time was 29.4 months. Out of the total group, 41% of patients achieved long-term clinical benefit following dilation and in 17% after only a single dilation. The median number of dilations per patient was one. A total of 35 (59%) patients required surgery for their stricture during follow-up. There were two (1.6%) perforations as a result of dilation, one in an anastomotic stricture (managed conservatively) and one in a de-novo stricture (requiring surgery). There were no deaths.

CONCLUSIONS

Colonoscopic balloon dilation of Crohn's strictures can achieve long-term clinical benefit in many patients. Repeat dilations are justified in initial non-responders. In this series, the procedure appears safe with low morbidity.

Therapeutic options in the management of strictures in Crohn's disease

Intestinal strictures are a commonly encountered problem in patients with Crohn's disease. Endoscopic management with hydrostatic balloon dilation is an effective alternative to surgery in patients with endoscopically accessible lesions that are shorter than 7-8 cm. Endoscopic balloon dilation is the preferred initial modality in anastomotic strictures. The presence of inflammation near the stricture should not be considered a contraindication to dilation, and intralesional steroid injection should be considered in these patients with inflammation present in the area of the stricture. Further technological developments in endoscopes and balloon dilators may allow for broader application of these techniques.

Review article: indication and type of surgery in Crohn's disease

The large majority of patients affected by Crohn's disease require surgery during their clinical history. Radical resection originally advocated for Crohn's disease does not decrease the recurrence rate, and repeated resections predispose patients to the development of short-bowel syndrome. Over the last few years, conservative surgery has become accepted by many authors as a safe means of treating obstructive Crohn's disease. In this review article we analyse the efficacy and safety of conservative techniques, in comparison with resective surgery. Indications, advantages and technical aspects of resective and conservative surgery are reported. The experience with 489 patients treated for complicated or treatment refractory Crohn's disease in our Institution suggests that strictureplasty is a safe and effective procedure in many cases, as reported by other authors. The risk of cancer in areas of active disease as in stenosis treated with strictureplasty seems to be negligible. Resective surgery still represents the 'gold standard' in patients with perforating Crohn's disease; however, conservative surgery, usually contraindicated in perforating Crohn's disease, can be advocated in patients with localized perforating disease presenting an actual risk of short bowel syndrome.

Preoperative characteristics and postoperative behavior of bowel wall on risk of recurrence after conservative surgery in Crohn's disease: a prospective study

OBJECTIVE

To evaluate in patients with Crohn's disease, using transabdominal ultrasound, the morphologic characteristics of the diseased bowel wall before and after conservative surgery and to assess whether these characteristics and their behavior in the postoperative follow-up are useful and reliable prognostic factors of clinical and surgical recurrence.

SUMMARY BACKGROUND DATA

Ultrasound is effective for evaluating the thickness of bowel wall, the most typical and constant finding of Crohn's disease. No data are currently available concerning the behavior of the diseased intestinal wall after conservative surgery and whether the preoperative characteristics of bowel wall or its behavior after conservative surgery may predict recurrence.

METHODS

In 85 consecutive patients treated with strictureplasty and miniresections for Crohn's disease, clinical and ultrasonographic evaluations were performed before and 6 months after surgery. Assessed before surgery were the maximum bowel wall thickness, the length of bowel wall thickening, the bowel wall echo pattern (homogeneous, stratified, and mixed), and the postoperative bowel wall behavior, classified as normalized, improved, unchanged, or worsened.

RESULTS

A significant correlation was found between a long preoperative bowel wall thickening and surgical recurrence. Bowel wall thickness after surgery was unchanged or worsened in 43.3% of patients; in these patients, there was a high frequency of previous surgery. Patients with unchanged or worsened bowel wall thickness had a higher risk of clinical and surgical recurrence compared with those with normalized or improved bowel wall thickness.

CONCLUSION

With the use of abdominal ultrasound, the authors found that the thickening of diseased bowel wall may unexpectedly improve after conservative surgery, and this is associated with a favorable outcome in terms of clinical and surgical recurrence. In addition to its diagnostic usefulness, ultrasound also provides reliable prognostic information concerning clinical and surgical recurrence in patients with Crohn's disease in the postoperative follow-up.

Safety and longterm efficacy of strictureplasty in 314 patients with obstructing small bowel Crohn's disease

BACKGROUND

Since its introduction in the early 1980s, strictureplasty (SXP) has become a viable option in the surgical management of obstructing small bowel Crohn's disease. Questions still remain regarding its safety and longterm durability in comparison to resection. Precise indications and contraindications to the procedure are also not well defined.

STUDY DESIGN

A retrospective review of all patients undergoing SXP for obstructing small bowel Crohn's disease at the Cleveland Clinic between 1984 and 1999 was conducted. A total of 314 patients underwent a laparotomy that included the index SXP The total number of SXPs performed was 1,124, with a median of two (range 1 to 19) per patient. Sixty-six percent of patients underwent a synchronous bowel resection. Recurrence was defined as the need for reoperation. Followup information was determined by personal interviews, phone interviews, or both.

RESULTS

The overall morbidity rate was 18%, with septic complications occurring in 5% of patients. Preoperative weight loss (p = 0.004) and older age (p = 0.008) were found to be significant predictors of morbidity. The surgical recurrence rate was 34%, with a median followup period of 7.5 years (range 1 to 16 years). Age was found to be a significant predictor of recurrence (p = 0.02), with younger patients having a shorter time to reoperation.

CONCLUSIONS

This large series of patients with longterm followup confirms the safety and efficacy of strictureplasty in patients with obstructing small bowel Crohn's disease. The 18% morbidity and 34% operative recurrence rates compare favorably with reported results of resective surgery. Caution should be used in patients with preoperative weight loss, because they experienced higher complication rates. Although young patients seem to follow an accelerated course, SXP remains indicated as part of an overall strategy to conserve intestinal length.

The history of Crohn's disease

Although it is likely that cases of what we know as granulomatous inflammatory bowel disease (Crohn's disease) may have been recorded as early as 1769, this illness is basically a disease of the 20th century. This historical review traces the development of our understanding of the disease and the evolution of its operative management.

Crohn's disease of the small bowel

Crohn's disease of the small bowel frequently requires surgical intervention. While dealing with the disease complications that require intervention, treatment should be based on a long-term strategic plan that recognizes the likelihood of recurrent disease, repeat surgeries, and the possibility of a future ostomy. Resection forms the basis for surgical treatments, but strictureplasty, abscess drainage, intestinal and diversion bypasses also are used, selectively.

Long-term outcome of surgical management for diffuse jejunoileal Crohn's disease

BACKGROUND

In diffuse jejunoileal Crohn's disease, resectional surgery may lead to short-bowel syndrome. Since 1980 strictureplasty has been used for jejunoileal strictures. This study reviews the long-term outcome of surgical treatment for diffuse jejunoileal Crohn's disease.

METHODS

The cases of 46 patients who required surgery for diffuse jejunoileal Crohn's disease between 1980 and 1997 were reviewed.

RESULTS

Strictureplasty was used for short strictures without perforating disease (perforation, abscess, fistula). Long strictures (<20 cm) or perforating disease was treated with resection. During an initial operation, strictureplasty was used on 63 strictures in 18 patients (39%). After a median follow-up of 15 years, there were 3 deaths: 1 from postoperative sepsis, 1 from small-bowel carcinoma, and 1 from bronchogenic carcinoma. Thirty-nine patients required 113 reoperations for jejunoileal recurrence. During 75 of the 113 reoperations (66%), strictureplasty was used on 315 strictures. Only 2 patients experienced the development of short-bowel syndrome and required home parenteral nutrition. At present, 4 patients are symptomatic and require medical treatment. All other patients are asymptomatic and require neither medical treatment nor nutritional support.

CONCLUSIONS

Most patients with diffuse jejunoileal Crohn's disease can be restored to good health with minimal symptoms by surgical treatment that includes strictureplasty.
