Abstract
Crohn's disease is an idiopathic inflammatory disorder of unknown etiology with genetic, immunologic, and environmental influences. The incidence of Crohn's disease has steadily increased over the past several decades. The diagnosis and treatment of patients with Crohn's disease has evolved since the last practice guideline was published. These guidelines represent the official practice recommendations of the American College of Gastroenterology and were developed under the auspices of the Practice Parameters Committee for the management of adult patients with Crohn's disease. These guidelines are established for clinical practice with the intent of suggesting preferable approaches to particular medical problems as established by interpretation and collation of scientifically valid research, derived from extensive review of published literature. When exercising clinical judgment, health-care providers should incorporate this guideline along with patient's needs, desires, and their values in order to fully and appropriately care for patients with Crohn's disease. This guideline is intended to be flexible, not necessarily indicating the only acceptable approach, and should be distinguished from standards of care that are inflexible and rarely violated. To evaluate the level of evidence and strength of recommendations, we used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The Committee reviews guidelines in depth, with participation from experienced clinicians and others in related fields. The final recommendations are based on the data available at the time of the production of the document and may be updated with pertinent scientific developments at a later time.

Tech Coloproctol 2017; 21:217-223. [PMID: 28205051 DOI: 10.1007/s10151-017-1591-2] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/23/2016] [Accepted: 12/28/2016] [Indexed: 02/06/2023]
Abstract
BACKGROUND Evaluating the impact of steroid or immunosuppressants (SI) therapy prior to colectomy in Crohn's disease (CD) patients on postoperative septic and colectomy-specific outcomes using the American College of Surgeons (ACS)-National Surgical Quality Improvement Program (NSQIP)-targeted colectomy database. METHODS All CD patients undergoing colectomy were retrieved from the 2012-2013 NSQIP-targeted database. Thirty-day postoperative outcomes were compared for patients who were on steroids or immunosuppressants (SI) within the 30 days prior to colectomy to the others using univariable and multivariable analyses. RESULTS Of 2208 CD patients, 1387 (63%) were on SI. Patients in the SI group were younger, and a greater proportion underwent laparoscopic surgery (p < 0.05). SI use was associated with a higher rate of sepsis (7.6 vs. 5.2%), anastomotic leak (5.6 vs. 3.5%), and return to operating room (6.8 vs. 3.3%). On multivariable analysis, SI was associated with sepsis, septic shock, and anastomotic leak [odds ratio = 1.58, 95% confidence interval 1.09-2.27]. CONCLUSIONS These results suggest that SI use within 30 days of colectomy is associated with a higher rate of sepsis and septic shock and anastomotic leak in CD patients. Withholding SI prior to surgery, or the selective use of an ostomy to mitigate the consequences of a leak and hence sepsis need due consideration prior to surgery.

Abstract
Patients with inflammatory bowel disease who experience abdominal pain and gastrointestinal symptoms often seek care in the emergency department (ED). These patients commonly undergo abdominopelvic computed tomography (CT) as part of their evaluation, and the rate of imaging appears to be increasing without a corresponding increase in identification of clinically actionable findings or effect on disposition. Studies demonstrate that the yield of CT tends to be fairly high. Yet, because inflammatory bowel disease is often diagnosed at an early age, these patients are repeatedly imaged during their lifetime, a subset of whom accumulate high levels of ionizing radiation exposure, increasing their risk of cancer. This compounds an already increased risk of cancer in these patients because of inflammatory bowel disease alone. Lack of intimate knowledge of a patient's disease phenotype and disease progression contributes to uncertainty in distinguishing between an inflammatory exacerbation; a complication such as obstruction, abscess, perforation, fistula, or stricture; and a noninflammatory-bowel-disease-related condition. This uncertainty can lead to overuse of imaging with CT. Limited availability of and lack of awareness of alternate imaging modalities and strategies may prevent providers from pursuing strategies that avoid ionizing radiation. In this article, we review options for imaging inflammatory bowel disease patients in the ED and attempts undertaken to risk stratify these patients, and we discuss ways in which details of a patient's disease might guide imaging decisionmaking.

Abstract
Anti-tumor necrosis factor therapy has revolutionized the treatment of Crohn's disease. Despite the increased use in the past decade and a half, a majority of patients with Crohn's disease with ultimately require operative management of their disease. No clear consensus has been made in the literature regarding the surgical outcomes in patients who have been exposed to anti-tumor necrosis factor therapy. This review highlights the most recent and relevant literature regarding the safety and effects of anti-tumor necrosis factor use in the perioperative period.

Abstract
BACKGROUND The impact of pregnancy on the course of Crohn disease is largely unknown. Retrospective surveys have suggested a variable effect, but there are limited population-based clinical data. We hypothesized pregnant women with Crohn disease will have similar rates of surgical disease as a nonpregnant Crohn disease cohort. MATERIAL AND METHODS International Classification of Diseases, Ninth Revision, Clinical Modification codes were used to identify female Crohn patients from all patients admitted using the Nationwide Inpatient Sample (1998-2009). Women were stratified as either pregnant or nonpregnant. We defined Crohn-related surgical disease as peritonitis, gastrointestinal hemorrhage, intra-abdominal abscess, toxic colitis, anorectal suppuration, intestinal-intestinal fistulas, intestinal-genitourinary fistulas, obstruction and/or stricture, or perforation (excluding appendicitis). RESULTS Of the 92,335 women admitted with a primary Crohn-related diagnosis, 265 (0.3%) were pregnant. Pregnant patients were younger (29 versus 44 y; P<0.001) and had lower rates of tobacco use (6% versus 13%; P<0.001). Pregnant women with Crohn disease had higher rates of intestinal-genitourinary fistulas (23.4% versus 3.0%; P<0.001), anorectal suppuration (21.1% versus 4.1%; P<0.001), and overall surgical disease (59.6% versus 39.2%; P<0.001). On multivariate logistic regression analysis controlling for malnutrition, smoking, age, and prednisone use, pregnancy was independently associated with higher rates of anorectal suppuration (odds ratio [OR], 5.2; 95% confidence interval [CI], 3.8-7.0; P<0.001), intestinal-genitourinary fistulas (OR, 10.4; 95% CI, 7.8-13.8; P<0.001), and overall surgical disease (OR, 2.9; 95% CI, 2.3-3.7; P<0.001). CONCLUSIONS Pregnancy in women with Crohn disease is a significant risk factor for Crohn-related surgical disease, in particular, anorectal suppuration and intestinal-genitourinary fistulas.

Abstract
Inflammatory bowel disease is a chronic inflammatory disorder of the gastrointestinal tract that includes both Crohn disease (CD) and ulcerative colitis. Abdominal pain, rectal bleeding, diarrhea, and weight loss characterize both CD and ulcerative colitis. The incidence of IBD in the United States is 70 to 150 cases per 100,000 individuals and, as with other autoimmune diseases, is on the rise. CD can affect any part of the gastrointestinal tract from the mouth to the anus and frequently will include perianal disease. The first description connecting regional enteritis with perianal disease was by Bissell et al in 1934, and since that time perianal disease has become a recognized entity and an important consideration in the diagnosis and treatment of CD. Perianal Crohn disease (PCD) is defined as inflammation at or near the anus, including tags, fissures, fistulae, abscesses, or stenosis. The symptoms of PCD include pain, itching, bleeding, purulent discharge, and incontinence of stool. In this report, we review and discuss the etiology, diagnosis, evaluation, and treatment of PCD.

Abstract
Although Crohn disease (CD) is considered an inflammatory bowel disease, extraintestinal gynecologic manifestations are varied, frequent, and oftentimes difficult to manage. Its predilection for young and reproductive-age women makes it an important disease process for the gynecologist to understand, as its complications can have long-term repercussions on the developmental, sexual, reproductive, and psychological health of affected women. Patients may present with a variety of vulvovaginal, perineal, perianal, and urologic complaints. Perianal involvement from an intestinal fistula is the most common skin manifestation seen in CD. Other gynecologic manifestations include metastatic CD and rectovaginal and urovaginal fistulas. Recognition and accurate diagnosis of extraintestinal gynecologic manifestations, as well as a good understanding of the gynecologic effects of chronic disease, are necessary for optimal management. The article provides an overview of CD and highlights the gynecologic considerations in caring for women affected by this disease.

Abstract
Crohn disease involves the perineum and rectum in approximately one-third of patients. Symptoms can range from mild, including skin tags and hemorrhoids, to unremitting and severe, requiring a proctectomy in a small, but significant, portion. Fistula-in-ano and perineal sepsis are the most frequent manifestation seen on presentation. Careful diagnosis, including magnetic resonance imaging or endorectal ultrasound with examination under anesthesia and aggressive medical management, usually with a tumor necrosis factor-alpha, is critical to success. Several options for definitive surgical repair are discussed, including fistulotomy, fibrin glue, anal fistula plug, endorectal advancement flap, and ligation of intersphincteric fistula tract procedure. All suffer from decreased efficacy in patients with Crohn disease. In the presence of active proctitis or perineal disease, no surgical therapy other than drainage of abscesses and loose seton placement is recommended, as iatrogenic injury and poor wound healing are common in that scenario.

Abstract
Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) with uncertain etiopathogenesis. CD can involve any site of gastrointestinal tract from the mouth to anus and is associated with serious complications such as bowel strictures, perforations, and fistula formation. The incidence and prevalence rates of CD in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Although there are no definitive curative modalities for CD, various medical and surgical therapies are currently applied for diverse clinical situations of CD. However, a lot of decisions on the management of CD are made depending on the personal experiences and choices of physicians. To suggest preferable approaches to diverse problems of CD and to minimize the variations according to physicians, guidelines for the management of CD are needed. Therefore, IBD Study Group of the Korean Association for the Study of the Intestinal Diseases has set out to develop the guidelines for the management of CD in Korea. These guidelines were developed using the adaptation methods and encompass the treatment of inflammatory disease, stricturing disease, and penetrating disease. The guidelines also cover the indication of surgery, prevention of recurrence after surgery, and CD in pregnancy and lactation. These are the first Korean guidelines for the management of CD and the update with further scientific data and evidences is needed.

Abstract
BACKGROUND Whereas Crohn's disease is traditionally thought to represent a wasting disease, little is currently known about the incidence and impact of obesity in this patient cohort. OBJECTIVE This study aimed to evaluate the perioperative outcomes in patients with Crohn's disease who were obese vs those who were not obese undergoing major abdominal surgery. DESIGN This study is a retrospective review of the American College of Surgeons National Surgical Quality Improvement Program database (2005-2008). Risk-adjusted 30-day outcomes were assessed by the use of regression modeling accounting for patient characteristics, comorbidities, and surgical procedures. PATIENTS Included were all patients with Crohn's disease who were undergoing abdominal operations. MAIN OUTCOME MEASURE The primary outcomes measured were short-term perioperative outcomes. Obesity was defined as a BMI of 30 or greater. RESULTS We identified 2319 patients (mean age, 41.6 y; 55% female). Of these patients, 379 (16%) met obesity criteria, 2% were morbidly obese, and 0.3% were super obese. Rates of obesity significantly increased each year over the study period. Twenty-five percent of the surgeries were performed laparoscopically (obese 21% vs nonobese 26%). Six percent were emergent, with no difference in patients with obesity. Operative times were significantly longer among patients with obesity (177 min) compared with patients who were not obese (164 min). After adjusting for differences in comorbidities and steroid use, overall perioperative morbidity was significantly higher in the obese cohort (32% vs 22% nonobese; OR 1.9). In addition, the rates of postoperative complications increased directly with rising BMI. Irrespective of procedure type, the patients who were obese were significantly more likely to experience wound infections (OR 1.7), which increased even further in patients who were morbidly obese (BMI >40; OR 7.1). By specific operation, postoperative morbidity was increased in patients with obesity following colectomies with primary anastomosis for both open and laparoscopic approaches (OR 2.9 and OR 3.8). Cardiac, pulmonary, and renal complications as well as overall mortality did not differ significantly based on BMI. LIMITATIONS This study was limited by being a retrospective review, and by using data limited to the American College of Surgeons National Surgical Quality Improvement Program database. CONCLUSION Increasing BMI adversely affects perioperative morbidity in patients with Crohn's disease.

Abstract
Crohn's disease manifests with perianal or rectal symptoms in approximately one-third of patients, and is associated with a more aggressive natural history. Due to the chronic relapsing nature of the disease, surgery has been traditionally avoided. However, combined medical and surgical intervention when treating perianal fistulae has been shown to offer the best chance for success. Endoanal ultrasound examination or pelvic magnetic resonance imaging should be done in conjunction with an examination under anesthesia to characterize the disease. Any abscess should be drained and setons placed if there is active rectal inflammation or complex fistulae. Antibiotics and immunosuppressive therapy (especially with infliximab) should also be initiated. Simple fistulae can be treated surgically by fistulotomy or anal fistula plug. Complex fistulae can be closed with either an anal fistula plug or covered with flaps. Up to 20% of patients anorectal Crohn's disease require proctectomy for persistent and disabling disease.

Abstract
PURPOSE The laparoscopic approach to Crohn's disease has demonstrated benefits in several small series. We sought to examine its use and outcomes on a national level. METHODS All admissions with a diagnosis of Crohn's disease requiring bowel resection were selected from the 2000-2004 Nationwide Inpatient Sample. Regression analyses were used to compare outcome measures and identify independent predictors of undergoing laparoscopy. RESULTS Of 396,911 patients admitted for Crohn's disease, 49,609 (12%) required surgical treatment. They were predominately Caucasian (64%), female (54%), and with ileocolic disease (72%). Most had private insurance (71%) and had surgery in urban hospitals (91%). Laparoscopic resection was performed in 2,826 cases (6%) and was associated with lower complications (8% vs. 16%), shorter length of stay (6 vs. 9 days), lower charges ($27,575 vs. $38,713), and mortality (0.2% vs. 0.9%, all P < 0.01). Open surgery was used more often for fistulas (8% vs. 1%) and when ostomies were required (12% vs. 7%). Independent predictors of laparoscopic resection were age <35 [odds ratio (OR) = 2.4], female gender (OR = 1.4), admission to a teaching hospital (OR = 1.2), ileocecal location (OR = 1.5), and lower disease stage (OR = 1.1, all P < 0.05). Ethnic category, insurance status, and type of admission (elective vs. non-elective) were not associated with operative method (P > 0.05). CONCLUSIONS A variety of patient- and system-related factors influence the utilization of laparoscopy in Crohn's disease. Laparoscopic resection is associated with excellent short-term outcomes compared to open surgery.

Abstract
INTRODUCTION We performed a meta-analysis to compare the clinical and endoscopic recurrence of medical treatment and placebo treatment for preventing postoperative recurrence in Crohn's disease. MATERIALS AND METHODS Trials were located through Medline, Embase, the Cochrane Central Register of Controlled Trials, Ovid, Sciencedirect, and Ingenta electronic databases. From 124 articles screened, 14 were identified as randomized placebo-controlled trials and were included for data extraction. Main outcome measures were clinical recurrence, endoscopic recurrence, and severe endoscopic recurrence. The meta-analysis was performed with the fixed-effects model. RESULT Fourteen studies with 1,497 participants were analyzed. In the intention-to-treat analysis, medical treatment was associated with a significantly lower incidence of clinical recurrence (relative risk of 0.74, 95% confidence interval 0.64-0.87, P = 0.000], but there were no significant differences in endoscopic recurrence (0.94, 0.83-1.07, P = 0.353) and severe endoscopic recurrence (0.83, 0.60-1.16, P = 0.281) between the two groups. When using per-protocol analysis, the results is similar, medical treatment was associated with a significantly lower incidence of clinical recurrence (0.84, 0.72-0.97, P = 0.020), but there were no significant differences in endoscopic recurrence (0.94, 0.85-1.05, P = 0.268) or severe endoscopic recurrence (0.76, 0.55-1.04, P = 0.084) between the two groups of patients. CONCLUSIONS Medical treatment has a sufficiently beneficial effect on decreasing the risk of clinical postoperative recurrence in patients with CD.

Abstract
Guidelines for clinical practice are intended to suggest preferable approaches to particular medical problems as established by interpretation and collation of scientifically valid research, derived from extensive review of published literature. When data that will withstand objective scrutiny are not available, a recommendation may be made based on a consensus of experts. Guidelines are intended to apply to the clinical situation for all physicians without regard to specialty. Guidelines are intended to be flexible, not necessarily indicating the only acceptable approach, and should be distinguished from standards of care that are inflexible and rarely violated. Given the wide range of choices in any health-care problem, the physician should select the course best suited to the individual patient and the clinical situation presented. These guidelines are developed under the auspices of the American College of Gastroenterology and its Practice Parameters Committee. Expert opinion is solicited from the outset for the document. The quality of evidence upon which a specific recommendation is based is as follows: Grade A: Homogeneous evidence from multiple well-designed randomized (therapeutic) or cohort (descriptive) controlled trials, each involving a number of participants to be of sufficient statistical power. Grade B: Evidence from at least one large well-designed clinical trial with or without randomization, from cohort or case-control analytic studies, or well-designed meta-analysis. Grade C: Evidence based on clinical experience, descriptive studies, or reports of expert committees. The Committee reviews guidelines in depth, with participation from experienced clinicians and others in related fields. The final recommendations are based on the data available at the time of the production of the document and may be updated with pertinent scientific developments at a later time.
