Long-term efficacy of strictureplasty for Crohn’s disease

First Mexican Consensus on Crohn's disease

INTRODUCTION

Crohn's disease (CD) is a subtype of chronic and incurable inflammatory bowel disease. It can affect the entire gastrointestinal tract and its etiology is unknown.

OBJECTIVE

The aim of this consensus was to establish the most relevant aspects related to definitions, diagnosis, follow-up, medical treatment, and surgical treatment of Crohn's disease in Mexico.

MATERIAL AND METHODS

Mexican specialists in the areas of gastroenterology and inflammatory bowel disease were summoned. The consensus was divided into five modules, with 69 statements. Applying the Delphi panel method, the pre-meeting questions were sent to the participants, to be edited and weighted. At the face-to-face meeting, all the selected articles were shown, underlining their level of clinical evidence; all the statements were discussed, and a final vote was carried out, determining the percentage of agreement for each statement.

RESULTS

The first Mexican consensus on Crohn's disease was produced, in which recommendations for definitions, classifications, diagnostic aspects, follow-up, medical treatment, and surgical treatment were established.

CONCLUSIONS

Updated recommendations are provided that focus on definitions, classifications, diagnostic criteria, follow-up, and guidelines for conventional medical treatment, biologic therapy, and small molecule treatment, as well as surgical management.

Strictureplasty may lead to increased preference in the surgical management of Crohn's disease: a case-matched study

BACKGROUND

Resection and strictureplasty are the two surgical modalities used in the management of Crohn's disease (CD). The objective of this study was to compare morbidity and clinical recurrence between patients who underwent strictureplasty and patients who underwent resection.

METHODS

Patients with CD who underwent strictureplasty between January 2012 and December 2022 were enrolled. The patients were well matched with patients who underwent resection without strictureplasty. Patient- and disease-specific characteristics, postoperative morbidity, and clinical recurrence were also analyzed.

RESULTS

A total of 118 patients who underwent a total of 192 strictureplasties were well matched to 118 patients who underwent resection. The strictureplasty group exhibited significantly less blood loss (30 ml versus 50 ml, p < 0.001) and stoma creation (2.5% versus 16.9%, p < 0.001). No significant difference was found regarding postoperative complications or length of postoperative stay. At the end of the follow-up, the overall rate of clinical recurrence was 39.4%, and no difference was observed between the two groups. Postoperative prophylactic use of biologics (odds ratio = 0.2, p < 0.001) was the only protective factor against recurrence.

CONCLUSION

Strictureplasty does not increase the risk of complications or recurrence compared with resection. It represents a viable alternative to resection in selected patients, and as such, it should have a broader scope of indications and greater acceptance among surgeons.

Results of the Eighth Scientific Workshop of ECCO: Diagnosing Postoperative Recurrence of Crohn's Disease After an Ileocolonic Resection With Ileocolonic Anastomosis

Despite the introduction of potent biologic therapies, many patients with Crohn's disease [CD] still require an ileocolonic resection [ICR] during the course of their disease. Furthermore, the need of redo ICR has not decreased over the past few decades, highlighting the need for better strategies to prevent and treat postoperative recurrence [POR]. The first step to develop such a strategy would be to define and standardise the description of POR with adequate diagnostic instruments. In this article, we will describe the different methodologies used to report POR [endoscopic, histological, radiological, biochemical, clinical, and surgical], and review their potential benefits and limitations, as well as the optimal timing of evaluation.

Endoscopy in the Surgically Altered Bowel

Improved utilization of surgical interventions to improve patient outcomes has led to an increased need to endoscopically evaluate and treat the bowel after surgery. The best outcomes are attained when the endoscopist coordinates with the surgeon, and in some cases the pathologist or radiologist to plan the procedure. Understanding the anatomy and pathology anticipated can allow planning for sedation, bowel cleanse and equipment needed. Surgically altered anatomy can create challenges that with planning can be overcome. This article will review how to prepare and navigate several of the most commonly encountered surgical interventions.

Intriguing Role of the Mesentery in Ileocolic Crohn's Disease

Crohn's disease (CD) is a chronic relapsing inflammatory bowel disease with unknown etiology. Up to 80% of patients will eventually require surgery throughout their lifetime, and often repeated resections are required for disease recurrence. Observations of “creeping fat” surrounding the diseased intestine renewed interest in the mesentery, recently defined as an organ with endocrine and immune functions. According to the inside-out model, the mesentery may be primarily affected in CD and subsequent cause alterations in the mucosa. Recently, lower surgical recurrence rates have been reported with en-bloc excision of the mesentery adjoining the diseased intestine. Results of ongoing randomized controlled trials may clarify the role of the mesentery in CD and possibly lead to its adoption as standard during surgery for Crohn's disease.

Non-conventional Versus Conventional Strictureplasties for Crohn's Disease. A Systematic Review and Meta-analysis of Treatment Outcomes

BACKGROUND

Strictureplasties [SXP] represent an alternative to bowel resection in Crohn's disease [CD]. Over the years, there has been growing interest in the role of non-conventional SXP for the treatment of extensive CD. A systematic review was performed on complications and recurrence following conventional and non-conventional SXP.

METHODS

The available literature was screened according to the PRISMA statement, until June 2020. Results were categorised into three groups: studies reporting on conventional SXPs; studies with a mixed cohort of conventional and non-conventional SXPs [% non-conventional SXPs ≤15%]; and studies reporting on non-conventional SXPs. Considered endpoints were postoperative complications and overall and SXP site-specific surgical recurrence. Random-effect meta-analysis and meta-regression were used to obtain and compare combined estimates between groups.

RESULTS

A total of 26 studies for a total of 1839 patients with CD were included. The pooled postoperative complication rates were was 15.5% (95% confidence interval [CI] 11.2%-20.3%), 7.4% [95% CI 0.2%-22.9%], and 19.2% [95% CI 5-39.6%] for the three groups, respectively. The rates of septic complications were 4% [95% CI 2.2%-6.2%], 1.9% [95% CI 0.4%-4.3%], and 4.2% [95% CI 0.9%-9.8%], respectively. Cumulative overall surgical recurrence rates were 27.5% [95% CI 18.5%-37.6%], 13.2% [95% CI 8.6%-18.7%], and 18.1% [95% CI 6.8%-33.3%]; and SXP site-specific surgical recurrence rates were 13.2% [95% CI 6.9%-21.2%], 8.3% [95% CI 1.6-19.3%], and 8.8% [95% CI 2.2%-19%], respectively. Formal comparison between the groups revealed no differences.

CONCLUSIONS

Non-conventional SXP did not differ from conventional SXP with respect to safety and long-term recurrence. Consistent heterogeneity was observed and partially limits the conclusions of this study.

Guidelines for the management of patients with Crohn's disease. Recommendations of the Polish Society of Gastroenterology and the Polish National Consultant in Gastroenterology

This paper is an update of the diagnostic and therapeutic recommendations of the National Consultant for Gastroenterology and the Polish Society of Gastroenterology from 2012. It contains 46 recommendations for the diagnosis and treatment, both pharmacological and surgical, of Crohn's disease in adults. The guidelines were developed by a group of experts appointed by the Polish Society of Gastroenterology and the National Consultant in the field of Gastroenterology. The methodology related to the GRADE methodology was used to assess the quality and strength of the available recommendations. The degree of expert support for the proposed statement, assessment of the quality of evidence and the strength of the recommendation was assessed on a 6-point Likert scale. Voting results, quality and strength ratings with comments are included with each statement.

Endoscopic evaluation of surgically altered bowel in inflammatory bowel disease: a consensus guideline from the Global Interventional Inflammatory Bowel Disease Group

The majority of patients with Crohn's disease and a proportion of patients with ulcerative colitis will ultimately require surgical treatment despite advances in diagnosis, therapy, and endoscopic interventions. The surgical procedures that are most commonly done include bowel resection with anastomosis, strictureplasty, faecal diversion, and ileal pouch. These surgical treatment modalities result in substantial alterations in bowel anatomy. In patients with inflammatory bowel disease, endoscopy plays a key role in the assessment of disease activity, disease recurrence, treatment response, dysplasia surveillance, and delivery of endoscopic therapy. Endoscopic evaluation and management of surgically altered bowel can be challenging. This consensus guideline delineates anatomical landmarks and endoscopic assessment of these landmarks in diseased and surgically altered bowel.

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.

Surgical treatment of intestinal stricture in inflammatory bowel disease

Fibroblast infiltration and collagen deposition result in structural changes in the bowel wall, and lead to strictures in intestinal inflammatory disease. While strictures can also occur in other contexts, such as malignancy, this review focuses on the surgical treatment of stricture secondary to inflammatory bowel disease. Distinguishing between predominantly inflammation vs established fibrosis as the cause of a stricture can be challenging. While inflammatory strictures may be responsive to medication, predominantly fibrotic strictures usually need surgical intervention. Both endoluminal and extraluminal approaches are described in this review. Endoscopic dilatation of strictures is suitable for short-segment isolated small bowel strictures. Other options are to divide the stricture surgically but preserve the length, performing a strictureplasty or resecting the strictured segment. The mesentery is increasingly recognized as playing a role in stricture recurrence. In a relapsing-remitting disease such as Crohn's disease, the preservation of intestinal length is essential and balance is needed between this and a complete resection to reduce the risk of recurrence. Pre- and postoperative involvement of the multidisciplinary team is essential to improve outcomes in this challenging clinical scenario.

ECCO Guidelines on Therapeutics in Crohn's Disease: Surgical Treatment

This article is the second in a series of two publications relating to the European Crohn's and Colitis Organisation [ECCO] evidence-based consensus on the management of Crohn's disease. The first article covers medical management; the present article addresses surgical management, including preoperative aspects and drug management before surgery. It also provides technical advice for a variety of common clinical situations. Both articles together represent the evidence-based recommendations of the ECCO for Crohn's disease and an update of previous guidelines.

The current therapeutic options for Crohn's disease: from medical therapy to intestinal transplantation

Crohn's disease (CD) has an annual incidence per 100.000 person-year of 20.2 in North America and 12.7 in Europe, and the purpose of this review is to evaluate its medical management, from diagnosis to transplant. Pharmacologic manipulation with nutritional care aims to achieve and maintain remission, but more than half of patients will undergo an intestinal resection, very often repeated over time. They could experience short bowel syndrome (SBS) requiring total parenteral nutrition (TPN). Intestinal transplantation (ITx) represents an alternative in case of irreversible intestinal failure (IF) with life-threatening TPN complications. Patient survival after ITx is 79%, 53% and 43% at 1, 3 and 5 years respectively, with no differences among ITx for other disorders. Areas covered: The research discussed medical therapy with nutritional support, evaluating the role of endoscopy, surgery and transplant in CD. A systematic literature review was conducted using the PubMed search engine up to May 31^th, 2017 without restriction of the language. The decision on paper's eligibility was reached by consensus between the 3 screening authors. Expert commentary: CD treatment is mainly medical, leaving endoscopy and surgery for a complex course. ITx represents a therapeutic option if TPN complications with IF arise.

Current challenges in the surgical management of Crohn's disease: a systematic review

BACKGROUND

Crohn's disease is a chronic inflammatory disorder, and the broad variability in phenotypic presentations makes the treatment of this disease a true multidisciplinary approach. We sought to review the current recommendations regarding the surgical management of Crohn's disease.

DATA SOURCE

A Systematic literature review of surgical techniques was performed from 1979 through 2015. We evaluated 30 articles focusing on findings over the past 5 years.

CONCLUSIONS

Crohn's is a complex disease with no surgical cure. Invasive techniques vary from strictureplasty to resection and percutaneous drainage of penetrating disease when indicated. There is a paucity of well-controlled randomized studies evaluating these surgical techniques, and therefore, we continue to rely on smaller studies and historical data. The surgical goals are to minimize postoperative complications while preserving intestinal length and slowing the progression to clinical recurrence. The evidence discussed is one strategy against this complex pathology.

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.

Resection leads to less recurrence than strictureplasty in a paediatric population with obstructive Crohn's disease

Introduction. Resection and strictureplasty are used to treat patients with obstructive Crohn's disease. Strictureplasty is preferable in adults as it retains bowel length. This study aims to identify differences in outcomes of children undergoing strictureplasty and resection for obstructive Crohn's disease. Method. Patients under 20 years undergoing surgery over a nine-year period were included. Data was collected on procedures for stenotic Crohn's disease. Patients were divided into 2 groups: Group 1 treated with strictureplasties and Group 2 resections. Postoperative complications and recurrence rates were recorded. Kaplan-Meier method was used to analyze the data. Results. Twenty-six patients and 40 operations were identified. Mean age was 15.6 years (7.2–19.4) with equal numbers of males and females. Mean follow-up was 45.9 months (0.1–149.9). 20/40 procedures involved the terminal ileum; 9/40, the ileocolic junction; 8/40, the upper GI tract; and 3/40, the colon. Group 1 consisted of 19 strictureplasties and Group 2 consisted of 13 resections and 8 combined procedures. Significantly more patients in Group 1 required further surgery (11/19 versus 3/21; P = 0.008). Conclusion. Allowing for variations in disease duration, severity, and previous medical management, these data suggest that resection is preferable to strictureplasty in treating obstructive Crohn's disease in children and adolescents.

Surgical stricturoplasty in the treatment of ileal pouch strictures

OBJECTIVE

The objective of this study was to evaluate the efficacy of stricturoplasty and endoscopic balloon dilatation in the treatment for ileal pouch strictures.

METHOD

Consecutive inflammatory bowel disease patients with pouch strictures seen at our Pouch Center from 2002 to 2012 were studied. The efficacy and safety of stricturoplasty (vs. endoscopic balloon dilation) were evaluated with both univariate and multivariate analyses.

RESULTS

A total of 167 patients met the inclusion criteria, including 16 (9.6 %) with surgical stricturoplasty and 151 (90.4 %) with endoscopic balloon dilation. Ninety-four patients (56.3 %) were male, with a mean age at the diagnosis of pouch stricture of 41.6 ± 13.2 years. Fifty-one patients (30.5 %) had multiple pouch strictures, while 100 (59.9 %) patients had strictures at the pouch inlet. The mean length of pouch strictures was 1.2 ± 0.6 cm. No difference was found between the stricturoplasty and endoscopic dilation groups in clinicopathological variables, except for the degree of strictures (p = 0.019). After a mean follow-up of 4.1 ± 2.6 years, pouch stricture recurred in 92 patients (55.1 %) and 21 (12.6 %) patients developed pouch failure. The time interval between the procedure and pouch stricture recurrence or pouch failure was longer in the stricturoplasty group than that in the endoscopic dilation group (p < 0.001). Patients in the two groups had similar overall pouch survival rates and stricture-free survival rates. In the multivariate analysis, stricturoplasty vs. endoscopic dilation was not significantly associated with either overall pouch survival or stricture-free survival. There was no difference in the procedure-associated complication rates between the two groups.

CONCLUSION

Surgical stricturoplasty and endoscopic dilation treatment are complimentary techniques for pouch strictures. Repeated endoscopic dilatations are often required, while surgical stricturoplasty appeared to yield a longer time interval to stricture recurrence or pouch failure.

Difference in recurrence patterns between anastomosis and strictureplasty after surgical treatment for crohn disease

This study aimed to investigate whether the initial indication for surgery or type of surgery (strictureplasty or resection) performed determines recurrence patterns in patients with Crohn disease. Recurrence patterns of 41 patients (31 patients: only resection and anastomosis of the intestine, and 10 patients: strictureplasty with/without resection and anastomosis) who underwent operation for recurrent Crohn disease (June 2002-December 2010) were evaluated. Strictureplasty for nonperforating disease was performed at 17 sites, and reoperation was required at 11 sites (10 sites for nonperforating disease and 1 site for perforating disease). There was a significant difference in the recurrence pattern in patients who underwent resection and anastomosis (P < 0.01) and in patients who underwent strictureplasty with resection and anastomosis (P < 0.05) between sites at which resection and anastomosis was performed for nonperforating and for perforating disease. Initial indication for surgery, but not the type of surgery, appeared to determine recurrence patterns.

A comprehensive review of inflammatory bowel disease focusing on surgical management

The two main diseases of inflammatory bowel disease are Crohn's disease and ulcerative colitis. The pathogenesis of inflammatory disease is that abnormal intestinal inflammations occur in genetically susceptible individuals according to various environmental factors. The consequent process results in inflammatory bowel disease. Medical treatment consists of the induction of remission in the acute phase of the disease and the maintenance of remission. Patients with Crohn's disease finally need surgical treatment in 70% of the cases. The main surgical options for Crohn's disease are divided into two surgical procedures. The first is strictureplasty, which can prevent short bowel syndrome. The second is resection of the involved intestinal segment. Simultaneous medico-surgical treatment can be a good treatment strategy. Ulcerative colitis is a diffuse nonspecific inflammatory disease that involves the colon and the rectum. Patients with ulcerative colitis need surgical treatment in 30% of the cases despite proper medical treatment. The reasons for surgical treatment are various, from life-threatening complications to growth retardation. The total proctocolectomy (TPC) with an ileal pouch anal anastomosis (IPAA) is the most common procedure for the surgical treatment of ulcerative colitis. Medical treatment for ulcerative colitis after a TPC with an IPAA is usually not necessary.

Comparison of conventional and nonconventional strictureplasties in Crohn's disease: a systematic review and meta-analysis

BACKGROUND

The Heineke-Mikulicz and Finney techniques are conventional strictureplasties that have been used to manage short (<10 cm) and medium-length (>10 cm and <20 cm) strictures from Crohn's disease. Nonconventional strictureplasty techniques have emerged to facilitate bowel conservation for atypical strictures. These techniques include the modified Finney, combined Heineke-Mikulicz and Finney, modified Heineke-Mikuliczs, Michelassi, and modifications of it and others.

OBJECTIVE

The aim of this study is to compare conventional vs nonconventional strictureplasties with respect to short-term complications and long-term results.

DATA SOURCES AND STUDY SELECTION

A MEDLINE search was performed using "Crohn's disease", "surgical therapy", "strictureplasty", "complications", "reoperation", and "recurrence" as medical subject headings. Studies conducted between 1975 and June 31, 2010 were found via PubMed, Ovid, Embase, and Cochrane databases and categorized into 3 groups. These groups consist of centers performing conventional strictureplasties, nonconventional strictureplasties, or both. Studies with at least 3 patients were reviewed.

INTERVENTIONS

A mixed-effects meta-analysis for each outcome was performed by use of Supermix software by SSI Scientific Software International.

MAIN OUTCOME MEASURES

We focused on immediate and long-term complication rates among the groups. The 6 immediate complications include small-bowel obstructions, sepsis, other infections, reoperations, early postoperative GI bleeds, and other early complications. The 5 long-term complications include recurrent strictures, small-bowel obstructions, reoperations, carcinoma, and deaths.

RESULTS

We reviewed 32 studies with 1616 patients who underwent 4538 strictureplasties. One thousand one hundred fifty-seven patients underwent conventional strictureplasties with an early complication rate of 15%; 459 patients underwent nonconventional strictureplasties with an early complication rate of 8%. A late complication rate of 29% for the conventional strictureplasty group and 17% for the nonconventional strictureplasty group was noted.

LIMITATIONS

We are limited by the data published with the inherent risk of finding and analyzing mostly articles with positive results.

CONCLUSION

The nonconventional strictureplasty techniques were noninferior to the conventional strictureplasty procedures with respect to all prespecified outcomes.

A comprehensive review of strictureplasty techniques in Crohn's disease: types, indications, comparisons, and safety

INTRODUCTION

Crohn's disease is one of the chronic inflammatory diseases of the gastrointestinal tract that is often complicated by stricture formation with resulting obstructive symptoms. The technical repertoire of strictureplasty procedures has increased over the years in an effort to manage the diverse presentations of this condition while limiting the need for bowel resection. In this comprehensive review, we describe, compare, categorize, and appraise the strengths and weaknesses of 15 unique strictureplasty techniques.

METHODS

To identify all unique strictureplasty procedures, a Medline search utilizing "Crohn's disease," "surgical therapy," "strictureplasty," "enteroenterostomy," "Heineke-Mikulicz," and "side-to-side isoperistaltic" strictureplasty as medical subject headings was completed. PubMed, Ovid, Embase, and Cochrane database searches were conducted. Relevant articles between 1980 to December 2010 were reviewed. We initially selected 58 articles, but only 18 introduced novel surgical procedures related to 15 types of strictureplasty in Crohn's disease.

RESULTS

We identified 15 types of strictureplasty techniques. These were categorized into three main groups. The revised nomenclature will facilitate the reader to understand the differences and utility of each technique. These groups include the Heineke-Mikulicz-like strictureplasties, the intermediate procedures, and the enteroenterostomies. Heineke-Mikulicz strictureplasty was the most frequently used technique.

CONCLUSION

Various techniques of strictureplasty have been reported in the published literature. Strictureplasty has been shown to be a safe and efficacious technique that is comparable to bowel resection for stricturing Crohn's disease. This technique spares bowel length and puts the Crohn's disease patient at a lower risk of developing short bowel syndrome with repeated resections.

Risk factors for short bowel syndrome in patients with Crohn's disease

PURPOSE

Patients with Crohn's disease (CD) often need home parenteral nutrition for short bowel syndrome (SBS), as a result of frequent surgery and extended bowel resections. We conducted this study to evaluate the influence of the patient's condition on the occurrence of SBS in CD.

METHODS

The subjects of this study were 721 patients, who underwent bowel resections for CD at Hyogo College of Medicine between September 1974 and September 2010. The collective total of bowel resection operations was 1286. The possible risk factors for SBS were analyzed by univariate and multivariate logistic regression analyses to determine their predictive significance.

RESULTS

SBS was diagnosed in 24 patients. A stepwise logistic regression model revealed that penetrating type (odds ratio 14.9, p = 0.02), remaining small intestine <200 cm (odds ratio 141.4, p < 0.01), ostomy creation (odds ratio 7.5, p = 0.03), and post-total colectomy (odds ratio 17.6, p < 0.01) were independent risk factors for SBS.

CONCLUSION

These results indicate that the length of remaining small bowel is closely related to SBS in patients who have undergone surgery for CD. At least 200 cm of small bowel should be preserved to prevent SBS when total colectomy and ostomy creation are performed for CD.
