Abstract
While both Crohn' disease (CD) and ulcerative colitis (UC) are known to predispose patients to certain intestinal malignancies, the exact mechanism of carcinogenesis remains unknown and optimal screening guidelines have not been established. This article will explore the history of our understanding of intestinal malignancy in inflammatory bowel disease (IBD). To contextualize the medical community's difficulty in linking each condition to cancer, the first section will review the discovery of CD and UC. Next, we discuss early attempts to define IBD's relationship with small bowel adenocarcinoma and colorectal cancer. The article concludes with a review of each disease's surgical history and the ways in which certain procedures produced poor oncologic outcomes.

Abstract
Chron’s Disease is a chronic inflammatory intestinal disease, first described at the beginning of the last century. The disease is characterized by the alternation of periods of flares and remissions influenced by a complex pathogenesis in which inflammation plays a key role. Crohn’s disease evolution is mediated by a complex alteration of the inflammatory response which is characterized by alterations of the innate immunity of the intestinal mucosa barrier together with a remodeling of the extracellular matrix through the expression of metalloproteins and increased adhesion molecules expression, such as MAcCAM-1. This reshaped microenvironment enhances leucocytes migration in the sites of inflammation, promoting a TH1 response, through the production of cytokines such as IL-12 and TNF-α. IL-12 itself and IL-23 have been targeted for the medical treatment of CD. Giving the limited success of medical therapies, the treatment of the disease is invariably surgical. This review will highlight the role of inflammation in CD and describe the surgical approaches for the prevention of the almost inevitable recurrence.

Abstract
Elective abdominal surgery for inflammatory bowel disease is common. Surgery for Crohn's disease is not curative, and treatment must be individualized to the disease process. Surgery for ulcerative colitis generally is curative but consideration of patient-specific factors is important for staging of the procedure and determining whether ileal pouch-anal anastomosis is appropriate.

Abstract
BACKGROUND AND AIMS Crohn's disease [CD] is associated with an increased risk of small bowel adenocarcinoma [SBA]. There are no recommendations on endoscopic screening of SBA in CD patients. The aim of this study was to evaluate the feasibility and value of endoscopic screening for SBA in CD patients at high-risk of SBA. METHODS We performed an exploratory multi-centre study in a prospective cohort of CD patients at high-risk of SBA defined as long-term small bowel disease without bowel resection for the past 10 years. Depending on the location of the disease, baseline upper and/or lower enteroscopies were performed. Random and targeted biopsies using chromoendoscopy were taken. Patients were followed-up for at least 1 year after inclusion. RESULTS In total, 101 patients [62 men; median age: 48 years; median duration of disease: 19 years] were recruited in ten centres. The endoscopic procedure was incomplete in 47 cases because of impassable strictures and dilation was performed in four patients. Indeterminate small bowel dysplasia was identified in two patients at endoscopic screening; SBA was confirmed in one after surgical resection. With an at least 1-year follow-up duration, two additional cases of SBA were identified in patients who underwent surgery for obstruction, resulting in a 33% sensitivity rate for SBA endoscopic screening. CONCLUSION In a cohort of high-risk patients, the prevalence of dysplasia and SBA on CD was 4%. Because of its low sensitivity, endoscopic screening cannot be recommended for surveillance in CD patients at high-risk of SBA.

Abstract
Patients with inflammatory bowel disease (IBD) have an increased risk of developing intestinal cancer. The magnitude of that increased risk as well as how best to mitigate it remain a topic of ongoing investigation in the field. It is important to quantify the risk of colorectal cancer in association with IBD. The reported risk varies widely between studies. This is partly due to the different methodologies used in the studies. Because of the limitations of surveillance strategies based on the detection of dysplasia, advanced endoscopic imaging and techniques involving the detection of alterations in mucosal antigens and genetic abnormalities are being investigated. Development of new biomarkers, predicting future occurrence of colonic neoplasia may lead to more biomarker-based surveillance. There are promising results that may lead to more efficient surveillance in IBD patients and more general acceptance of its use. A multidisciplinary approach, involving in particular endoscopists and pathologists, together with a centralized patient management, could help to optimize treatments and follow-up measures, both of which could help to reduce the IBD-associated cancer risk.

Abstract
Patients with inflammatory bowel diseases (IBD) have an excess risk of certain gastrointestinal cancers. Much work has focused on colon cancer in IBD patients, but comparatively less is known about other more rare cancers. The European Crohn's and Colitis Organization established a pathogenesis workshop to review what is known about these cancers and formulate proposals for future studies to address the most important knowledge gaps. This article reviews the current state of knowledge about small bowel adenocarcinoma, ileo-anal pouch and rectal cuff cancer, and anal/perianal fistula cancers in IBD patients.

Abstract
Surgery is well-established option for the treatment of Crohn's disease that is refractory to medical therapy and for complications of the disease, including strictures, fistulas, abscesses, bleeding that cannot be controlled endoscopically, and neoplastic degeneration. For a condition like Crohn's disease, where medical management is the rule, other indications for surgery are considered controversial, because the therapeutic effects of surgery are limited to the resolution of complications and the rate of recurrence is high, especially at sites of the surgical anastomosis. In the authors' opinion, however, surgery should not be considered a last-resort treatment: in a variety of situations, it should be regarded as an appropriate solution for managing this disease. Based on a review of the literature and their own experience, the authors examine some of the possibilities for surgical interventions in Crohn's disease and the roles played in these cases by diagnostic imaging modalities.

Abstract
PURPOSE The aim of this study was to analyze the clinical, pathological, and CT-enterography findings of small bowel adenocarcinomas in Crohn disease patients. MATERIALS AND METHODS Clinical, histopathological, and imaging findings were retrospectively evaluated in seven Crohn disease patients with small bowel adenocarcinoma. CT-enterography examinations were reviewed for morphologic features and location of tumor, presence of stratification, luminal stenosis, proximal dilatation, adjacent lymph nodes, and correlated with findings at histological examination. RESULTS The tumor was located in the terminal (n = 6) or distal (n = 1) ileum. On CT-enterography, the tumor was visible in five patients, whereas two patients had no visible tumor. Four different patterns were individualized including small bowel mass (n = 2), long stenosis with heterogeneous submucosal layer (n = 2), short and severe stenosis with proximal small bowel dilatation (n = 2), and sacculated small bowel loop with irregular and asymmetric circumferential thickening (n = 1). Stratification, fat stranding, and comb sign were present in two, two, and one patients, respectively. CONCLUSION Identification of a mass being clearly visible suggests strongly the presence of small bowel adenocarcinoma in Crohn disease patients but adenocarcinoma may be completely indistinguishable from benign fibrotic or acute inflammatory stricture. Knowledge of these findings is critical to help suggest the diagnosis of this rare but severe complication of Crohn disease.

Abstract
BACKGROUND Patients with long-standing colitis carry an increased risk of colorectal cancer and are therefore enrolled in colonoscopic surveillance programs. It is presently not known if endoscopic surveillance of patients with colitis with a closed rectal stump after a subtotal colectomy is justified. Neither is it clear which of these patients might be at increased risk for rectal stump cancer. OBJECTIVE The aim of this study is to identify the risk factors for rectal stump cancer. DESIGN This investigation is a retrospective descriptive case-control study. SETTINGS This study was conducted at tertiary referral centers in the Netherlands. PATIENTS Colorectal cancer cases associated with inflammatory bowel disease diagnosed between 1990 and 2006 were selected in a nationwide pathology archive. Patients with rectal stump cancer were selected from this group. The pathology archive was also used to identify inflammatory bowel disease controls matched for referral center with a closed rectal stump after subtotal colectomy, but without neoplasia. Follow-up started at the date of subtotal colectomy with the formation of a rectal stump. Demographic and disease characteristics were collected at baseline. MAIN OUTCOME MEASUREMENTS Hazard ratios with 95% confidence intervals were calculated for factors associated with the development of rectal stump cancer with the use of univariate Cox regression analysis. End points were rectal stump cancer, end of follow-up, or death. RESULTS A total of 12 patients with rectal stump cancer and 18 matching controls without neoplasia were identified. Univariate analysis showed an association between rectal stump cancer and primary sclerosing cholangitis, and disease duration until subtotal colectomy. LIMITATIONS This study is limited by its retrospective design, and, despite being the largest series to date, it still has a limited number of cases. CONCLUSIONS Risk factors for rectal stump cancer in a closed rectal stump after subtotal colectomy were primary sclerosing cholangitis and disease duration until subtotal colectomy.

Abstract
Chronic inflammation is thought to be the leading cause of many human cancers including colorectal cancer (CRC). Accordingly, epidemiologic and clinical studies indicate that patients affected by ulcerative colitis and Crohn’s disease, the two major forms of inflammatory bowel disease, have an increased risk of developing CRC. In recent years, the role of immune cells and their products have been shown to be pivotal in initiation and progression of colitis-associated CRC. On the other hand, activation of the immune system has been shown to cause dysplastic cell elimination and cancer suppression in other settings. Clinical and experimental data herein reviewed, while confirming chronic inflammation as a risk factor for colon carcinogenesis, do not completely rule out the possibility that under certain conditions the chronic activation of the mucosal immune system might protect from colonic dysplasia.

Abstract
BACKGROUND An association between small bowel adenocarcinoma and Crohn's disease (CD) is well-established. We present our recent experience with this entity in order to further elucidate its clinicopathological features and update our series from 1991. METHODS A retrospective review was undertaken of all surgical patients with small bowel adenocarcinoma and CD seen at our institution between 1993 and 2009. Follow-up was assessed until time of death or by interview with survivors. Survival was calculated based on TNM (tumor extent, lymph node status, metastases staging) staging and comparing between our current and previous series. RESULTS Twenty-nine patients (ten females and 19 males) were identified and followed for a median of 2 years. The median age at onset of CD symptoms was 25, and the median age at cancer diagnosis was 55.4, for a mean interval of 25.3 years. Twenty-two cancers were ileal and five were jejunal. There were no cancers in excluded intestinal loops. Significant differences in 2-year survival were determined for: node-negative (79.3%, 95%CI 58.3-100%) versus node-positive cancers (49% %, 95%CI 20.0-78.0%), and for localized (92.3%, 95%CI 77.8-100%) versus metastatic disease (33.3%, 95%CI 6.6-60%). Overall 36-month survival was 69.3% (95%CI 51.5-87.1%) compared to 40% among those without excluded loops in our series from 1991. Sixteen patients had long periods of quiescent disease before diagnosis (7-45 years), and 16 required surgery for bowel obstruction that was refractory to medical management. Adequate information was not retrievable for three patients. CONCLUSIONS A comparison to our previous series reveals similar clinical characteristics and a high rate of node-positive cancer at diagnosis. Our findings also confirm two important clinical indicators of malignancy: recrudescent symptoms after long periods of relative quiescence and small bowel obstruction that is refractory to medical therapy.

Abstract
PURPOSE The mucosa of the small intestine encompasses about 90% of the luminal surface area of the digestive system, but only 2% of the total annual gastrointestinal cancer incidence in the United States. METHODS The remarkable contrast in age-standardized cancer incidence between the small and large intestine has been reviewed with respect to the cell type patterns, demographic features, and molecular characteristics of neoplasms. RESULTS Particularly noteworthy is the predominance of adenocarcinoma in the colon, which exceeds 98% of the total incidence by cell type, in contrast to that of 30% to 40% in the small intestine, resulting in an age-standardized ratio of rates exceeding 50-fold. The prevalence of adenomas and carcinomas is most prominent in the duodenum and proximal jejunum. The positive correlation in global incidence rates of small and large intestinal neoplasms and the reciprocal increases in risk of second primary adenocarcinomas suggest that there are common environmental risk factors. The pathophysiology of Crohn inflammatory bowel disease and the elevated risk of adenocarcinoma demonstrate the significance of the impaired integrity of the mucosal barrier and of aberrant immune responses to luminal indigenous and potentially pathogenic microorganisms. CONCLUSION In advancing a putative mechanism for the contrasting mucosal susceptibilities of the small and large intestine, substantial differences are underscored in the diverse taxonomy, concentration and metabolic activity of anaerobic organisms, rate of intestinal transit, changing pH, and the enterohepatic recycling and metabolism of bile acids. Experimental and epidemiologic studies are cited that suggest that the changing microecology, particularly in the colon, is associated with enhanced metabolic activation of ingested and endogenously formed procarcinogenic substrates.

Abstract
Patients with long-standing inflammatory bowel disease (IBD) have an increased risk of developing colorectal cancer (CRC). Many of the molecular alterations responsible for sporadic colorectal cancer, namely chromosomal instability, microsatellite instability, and hypermethylation, also play a role in colitis-associated colon carcinogenesis. Colon cancer risk in inflammatory bowel disease increases with longer duration of colitis, greater anatomic extent of colitis, the presence of primary sclerosing cholangitis, family history of CRC and degree of inflammation of the bowel. Chemoprevention includes aminosalicylates, ursodeoxycholic acid, and possibly folic acid and statins. To reduce CRC mortality in IBD, colonoscopic surveillance with random biopsies remains the major way to detect early mucosal dysplasia. When dysplasia is confirmed, proctocolectomy is considered for these patients. Patients with small intestinal Crohn's disease are at increased risk of small bowel adenocarcinoma. Ulcerative colitis patients with total proctocolectomy and ileal pouch anal-anastomosis have a rather low risk of dysplasia in the ileal pouch, but the anal transition zone should be monitored periodically. Other extra intestinal cancers, such as hepatobiliary and hematopoietic cancer, have shown variable incidence rates. New endoscopic and molecular screening approaches may further refine our current surveillance guidelines and our understanding of the natural history of dysplasia.

Abstract
Both ulcerative colitis and Crohn’s disease carry an increased risk of developing colorectal cancer. Established risk factors for cancer among patients with inflammatory bowel disease (IBD) include the younger age at diagnosis, greater extent and duration of disease, increased severity of inflammation, family history of colorectal cancer and coexisting primary sclerosing cholangitis. Recent evidence suggests that current medical therapies and surgical techniques for inflammatory bowel disease may be reducing the incidence of this complication. Nonetheless heightened vigilance and a careful, comprehensive approach to prevent or minimize the complications of invasive cancer are warranted in this unique cohort of patients. Current guidelines for the prevention and early detection of cancer in this high risk population are grounded in the concept of an inflammation-dysplasia-carcinoma sequence. A thorough understanding of the definition and natural history of dysplasia in IBD, as well as the challenges associated with detection and interpretation of dysplasia are fundamental to developing an effective strategy for surveillance and prevention, and understanding the limitations of the current approach to prevention. This article reviews the current consensus guidelines for screening and surveillance of cancer in IBD, as well as presenting the evidence and rationale for chemoprevention of cancer and a discussion of emerging technologies for the detection of dysplasia.

Abstract
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.

Abstract
Colonic adenocarcinoma frequently complicates inflammatory bowel disease of the colon, but small bowel adenocarcinoma (SBA) is a rare complication of Crohn's disease (CD). We present two patients with SBA in CD and review the literature with regards to CD-related SBA. A 45-year-old male with a 17-year history of ileal CD presented with obstructive symptoms but no radiographic evidence of a mass. After laparoscopic ileocolectomy and repair of incidental ileosigmoid fistula, pathology showed a T3N0 adenocarcinoma within the ileal CD. Two years after his resection he was without evidence of disease. A 59-year-old male with a 15-year history of CD presented with an acute exacerbation. Small bowel follow through demonstrated a long ileal stricture for which he underwent an ileocolic resection. Postoperative pathology confirmed a T3N1 CD-related SBA. He died from metastatic cancer 3 months later. Review of the literature identified 154 cases of SBA complicating CD with several distinguishing features from de novo SBA. Patients with SBA and CD are, as a group, younger and more likely to be male. SBA is rarely diagnosed preoperatively in these patients, and has a poor prognosis due to its advanced stage at diagnosis.

Abstract
PURPOSE This study was designed to review safety and efficacy of strictureplasty for Crohn's disease. METHODS A literature search was performed to identify studies published between 1975 and 2005 that reported the outcome of strictureplasty. Systematic review was performed on the following subjects separately: 1) overall experience of strictureplasty; 2) postoperative complications; 3) postoperative recurrence and site of recurrence; 4) factors affecting postoperative complications and recurrence; 5) short-bowel syndrome; and 6) cancer risk. Meta-analysis of recurrence rate after strictureplasty was performed by using random-effect model and meta-regressive techniques. RESULTS A total of 1,112 patients who underwent 3,259 strictureplasties (Heineke-Mikulicz, 81 percent; Finney, 10 percent; side-to-side isoperistaltic, 5 percent) were identified. The sites of strictureplasty were jejunum and/or ileum (94 percent), previous anastomosis (4 percent), duodenum (1 percent), and colon (1 percent). After jejunoileal strictureplasty, including ileocolonic strictureplasty, septic complications (leak/fistula/abscess) occurred in 4 percent of patients. Overall surgical recurrence was 23 percent (95 percent confidence interval, 17-30 percent). Using meta-regressive analysis, the five-year recurrence rate after strictureplasty was 28 percent. In 90 percent of patients, recurrence occurred at nonstrictureplasty sites, and the site-specific recurrence rate was 3 percent. Two patients developed adenocarcinoma at the site of previous jejunoileal strictureplasty. The experience of duodenal or colonic strictureplasty was limited. CONCLUSIONS Strictureplasty is a safe and effective procedure for jejunoileal Crohn's disease, including ileocolonic recurrence, and it has the advantage of protecting against further small bowel loss. However, the place for strictureplasty is less well defined in duodenal and colonic diseases.

Abstract
There has been a multitude of case reports, case series, hospital-based, and population-based studies that link CD to various types of cancers. When each of these studies is scrutinized, however, there is only enough evidence to support a link between colorectal adenocarcinoma, SBA, and squamous and adenocarcinomas that are associated with perianal fistulizing disease. All of the studies of large bowel adenocarcinoma or SBA follow patients in an era during which there were far fewer effective medicines to treat CD and surgery was more commonplace. The only surveillance study of patients who had extensive, long-duration Crohn's colitis showed a 22% risk for developing neoplasia (low-grade, high-grade, or cancer) after four surveillance examinations. Overall results from this study and the multitude of the other studies show that the risk for cancer in Crohn's colitis is equal to that in UC given equal extent and duration of disease. Patients who have Crohn's colitis that affects at least one third of the colon and with at least 8 years of disease should undergo screening and surveillance, just as in UC. Although the absolute risk for SBA in CD is low (2.2% at 25 years in one study), we should not rule out screening and surveying for this complication that is associated with significant morbidity and mortality in patients who have long-standing, extensive, small bowel disease. The risk for lymphoma and leukemia in CD is low, but immunomodulators and biologics may increase this risk. The evidence that links carcinoid tumors to CD is weak, and population-based studies need to be done. The study of cancers that are associated with CD is an evolving field that surely will change given that immunomodulators and biologics are being used with greater frequency.

Abstract
BACKGROUND Patients with longstanding ulcerative colitis and colonic Crohn's disease have an increased risk of colorectal cancer compared with the general population. This review assesses the evidence that endoscopic surveillance may prolong life by allowing earlier detection of colon cancer or its pre-cursor lesion, dysplasia, in patients with inflammatory bowel disease. OBJECTIVES To assess the effectiveness of cancer surveillance programs in reducing the death rate from colorectal cancer in patients with ulcerative colitis and colonic Crohn's disease. SEARCH STRATEGY The following strategies were used to identify relevant studies:1. MEDLINE and the Cochrane Central Register of Controlled Trials were searched from 1966 to August 2005. The medical subject headings "Ulcerative Colitis", "Crohn Disease" or "Inflammatory Bowel Disease" and "Surveillance" or "Cancer" were used to perform key-word searches of the databases.2. Hand searching of reference lists from papers. SELECTION CRITERIA Potentially relevant articles were reviewed independently and unblinded by three authors to determine if they fulfilled the selection criteria. Each article was rated as being eligible, ineligible, or without sufficient information to determine eligibility. Any disagreement between reviewers was resolved by consensus. Any trials published in abstract form were only considered if it was possible to obtain full details of the protocol and results from the authors. DATA COLLECTION AND ANALYSIS Eligible articles were reviewed in duplicate and the results of the primary research trials were abstracted onto specially designed data extraction forms. The proportion of patients dying from bowel cancer or other causes in the control and surveillance groups of each study was derived from life tables, survival curves or where possible, by calculating life tables from the data provided. Data from the original research articles were converted into 2x2 tables (survival versus death x surveillance versus control) for each of the individual studies for comparable follow-up intervals. The presence of significant heterogeneity among studies was tested by the chi-square test. Because this is a relatively insensitive test, a P value of less than 0.1 was considered statistically significant. Provided statistical heterogeneity was not present, the fixed effects model was used for the pooling of data. The 2x2 tables were combined into a summary test statistic using the pooled relative risk (RR) and 95% confidence intervals as described by Cochrane and Mantel and Haenszel. MAIN RESULTS Karlen 1998a in a nested case-control study comprising 142 patients from a study population of 4664 UC patients, found that 2/40 patients dying of colorectal cancer had undergone surveillance colonoscopy on at least one occasion compared with 18/102 controls (RR 0.28, 95% CI 0.07 to 1.17). One of 40 patients who died from colorectal cancer had undergone surveillance colonoscopies on two or more occasions compared with 12/102 controls (RR 0.22, 95% CI 0.03 to 1.74) in contrast to a more modest effect observed for patients who had only one colonoscopy (RR 0.43, 95% CI 0.05 to 3.76). Choi 1993 found that carcinoma was detected at a significantly earlier stage in the surveilled patients; 15/19 had Duke's A or B carcinoma in the surveilled group compared to 9/22 in the non-surveilled group (P = 0.039). The 5-year survival rate was 77.2% for cancers occurring in the surveillance group and 36.3% for the no-surveillance group (P = 0.026). Four of 19 patients in the surveillance group died from colorectal cancer compared to 11 of 22 patients in the non-surveillance group (RR 0.42, 95% CI 0.16 to 1.11). Lashner 1990 found that four of 91 patients in a surveillance group died from colorectal cancer compared to 2 of 95 patients in a non-surveilled group (RR 2.09, 95% CI 0.39 to 11.12). Colectomy was less common in the surveillance group, 33 compared to 51 (P < 0.05) and was performed four years later (after 10 years of disease) in the surveillance group. For the pooled data analysis 8/110 patients in the surveillance group died from colorectal cancer compared to 13/117 patients in the non-surveillance group (RR 0.81, 95% CI 0.17 to 3.83). AUTHORS' CONCLUSIONS There is no clear evidence that surveillance colonoscopy prolongs survival in patients with extensive colitis. There is evidence that cancers tend to be detected at an earlier stage in patients who are undergoing surveillance, and these patients have a correspondingly better prognosis, but lead-time bias could contribute substantially to this apparent benefit. There is indirect evidence that surveillance is likely to be effective at reducing the risk of death from IBD-associated colorectal cancer and indirect evidence that it may be acceptably cost-effective.

Abstract
One of the most common beliefs in the management of Crohn's disease is that surgery should be considered only as a last resort. Surgery is often considered by patients and gastroenterologists to represent a "failure." However, the role of surgery in the care of patients with Crohn's disease has increasingly become a collaborative effort, with surgeons involved in many aspects of the management of these patients. This is particularly true in pediatric patients, as issues of growth and development may involve surgical intervention at earlier stages than might be required in older patients. In fact, surgical interventions may be indicated at any stage of the disease process. For example, early examination under anesthesia with abscess drainage and delineation of fistula tracts has proven very useful in patients with complex perineal disease. Surgery may contribute to the medical management of the disease by way of providing chronic enteral or parenteral access for nutritional interventions such as elemental feedings and total parenteral nutrition. Finally, surgical treatment of intra-abdominal complications including fistulas, phlegmon, and bowel strictures may have a dramatic impact on patient symptoms and side effects. Although bowel resection carries the long-term risk of short bowel syndrome should future resections be required, the improvements in medical therapy continue to reduce the risk of recurrent disease, making surgical resection more palatable. Surgical treatment of complicated disease offers significant potential to limit toxic medical therapy and improve quality of life. In addition, application of minimally invasive techniques can minimize the impact of insults to body image in this vulnerable patient population as well as speed recovery. Future interventions may be facilitated by reducing adhesion formation through the use of minimally invasive techniques. The dynamic nature of growth and development in the pediatric population presents unique complications from medical therapies that are different from those seen in adults. Criteria for surgical intervention must be interpreted in light of the specific challenges facing the pediatric population as frequently pointed out in the oft-quoted maxim, "children are not small adults!"

Abstract
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.

Abstract
BACKGROUND Small bowel adenocarcinoma is an uncommon complication of Crohn's disease. We sought to describe the clinical features, outcomes, and risk factors of small bowel adenocarcinoma in Crohn's disease. METHODS A centralized diagnostic index identified all patients with Crohn's disease with small bowel adenocarcinoma evaluated at our institution between 1976 and 2000, and the medical records were abstracted. Two controls with Crohn's disease were selected for each case, matched by gender and age. RESULTS Nine cases (four males) were identified. The patients presented with abdominal pain (89%), obstruction (89%), and weight loss (78%). Cancer was located in the ileum in 8 patients (89%) and the jejunum in 1 patient (11%). All cases but 1 had either lymph node involvement or metastasis. All cases had surgery, with 1 receiving adjuvant chemotherapy. No significant risk factors were found. The mortality rates at 1 and 2 years were 42% and 61%. CONCLUSIONS Small bowel adenocarcinoma is a rare complication of Crohn's disease that typically involves the ileum. Affected patients have symptomatic, advanced malignancies upon diagnosis. No significant risk factors were identified.

Choi 1993 found that carcinoma was detected at a significantly earlier stage in the surveillance group; 15/19 had Duke's A or B carcinoma in the surveilled group compared to 9/22 in the non-surveilled group (P= 0.039). The 5-year survival rate was 77.2% for cancers occurring in the surveillance group and 36.3% for the no-surveillance group (P= 0.026). Four of 19 patients in the surveillance group died from colorectal cancer compared to 11 of 22 patients in the non-surveillance group (RR 0.42, 95% CI 0.16 to 1.11). Lashner 1990 found that four of 91 patients in the surveillance group died from colorectal cancer compared to 2 of 95 patients in the non-surveilled group (RR 2.09, 95% CI 0.39 to 11.12). Colectomy was less common in the surveillance group, 33 compared to 51 (p < 0.05) and was performed four years later (after 10 years of disease) in the surveillance group. For the pooled data analysis 8/110 patients in the surveillance group died from colorectal cancer compared to 13/117 patients in the non-surveillance group (RR 0.81, 95% CI 0.17 to 3.83). REVIEWERS' CONCLUSIONS There is no clear evidence that surveillance colonoscopy prolongs survival in patients with extensive colitis. There is evidence that cancers tend to be detected at an earlier stage in patients who are undergoing surveillance and these patients have a correspondingly better prognosis but lead-time bias could contribute substantially to this apparent benefit. There is indirect evidence that surveillance is likely to be effective at reducing the risk of death from IBD-associated colorectal cancer and indirect evidence that it is acceptably cost-effective.

Abstract
The heterogeneous nature of Crohn's disease (CD) is reflected in the diversity of treatment options available for individual patients. The stratification of CD patients into more homogeneous groups based on disease location and disease behavior may provide clinicians with a more focused approach to therapeutic decision-making. Uncomplicated disease behaviors are typically treated medically. When complications arise and patterns of disease become more aggressive, combined medical and surgical approaches are often necessary and yield favorable results. The surgical management of CD can be as complex as the disease itself, and should involve a surgeon who professes a special expertise in inflammatory bowel disease. Progress in our understanding of the role of the interaction between the environment and the immune system in disease development has led to major advancements in the area of CD therapeutics. Current therapies target the various elements of the inflammatory cascade implicated in the pathogenesis of CD. The anti-inflammatory properties of the pharmacologic therapies presented in this review vary from actions that are extremely broad to those that are cellular or cytokine specific. Maximizing the efficacy of CD-directed therapies while minimizing their toxicity remains the principal objective in developing management strategies for CD patients. Maintaining good quality of life and maximizing adherence to therapies are also important considerations. Despite the various therapeutic options available for CD patients, chosen therapies should be based on the overall treatment goal for individual patients. Therapeutics can be broadly categorized as induction therapies (goal to treat active disease) and maintenance therapies (goal to prevent relapse of disease).

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
PURPOSE The aim of this study was to review the long-term outcome of strictureplasty for small-bowel Crohn's disease. METHODS We reviewed 111 patients who underwent 285 primary strictureplasties (Heineke-Mikulicz, 236; Finney, 49) between 1980 and 1997. RESULTS Eighty-seven patients (78 percent) had had previous bowel resections. Forty-six patients (41 percent) required synchronous resection for perforating disease (abscess or fistula) or long strictures (>20 cm). The mean number of strictureplasties was three (range, 1-11). There were no operative deaths. Septic complications (fistula or intra-abdominal abscess) related to strictureplasty developed in eight patients (7 percent), of whom two required a proximal ileostomy. Abdominal symptoms were relieved in 95 percent of patients. The majority (95 percent) of patients with preoperative weight loss gained weight (median gain, +2 kg; range, -6 to +22.3 kg). After a median follow-up of 107 months, symptomatic recurrence occurred in 60 patients (54 percent). In 11 patients symptomatic recurrence was successfully managed by medical treatment. Forty-nine patients (44 percent) required reoperation for recurrence: strictureplasty alone in 22 patients, resection alone in 19 patients, strictureplasty and resection in 6 patients, and ileostomy alone in 2 patients. Eighteen patients (16 percent) required a third operation. One patient died from a small-bowel carcinoma which developed in the vicinity of a previous strictureplasty. Two of 19 patients with diffuse jejunoileal disease developed short-bowel syndrome, and were receiving longterm parenteral nutrition. Two other patients were taking corticosteroids for recurrent symptoms. All other patients were asymptomatic, receiving neither medical treatment nor nutritional support. CONCLUSIONS Strictureplasty is a safe and efficacious procedure for small-bowel Crohn's disease in the long-term.

Abstract
OBJECTIVE The long-term outcome of strictureplasty for Crohn's disease is unknown. There have been few reports that have examined the predictive factors for outcome after strictureplasty. This study was undertaken to assess the long-term results and predictive factors for outcome following strictureplasty for jejunoileal Crohn's disease. PATIENTS AND METHODS Thirty-eight patients who underwent primary strictureplasty for jejunoileal Crohn's disease between 1980 and 1987 were reviewed. RESULTS Four patients developed an enterocutaneous fistula, of whom two had an intra-abdominal abscess. Two patients died during this study (one from leukaemia and another from small bowel carcinoma) and one patient was lost to follow up. All other patients have been followed for> 10 years. The 5- and 10-year cumulative reoperation rates for recurrence at the previous jejunoileal strictureplasty sites (site-specific recurrence) were 26% and 29%, respectively, after a median follow up of 13.5 years. After 5 years only one patient required surgery for site-specific recurrence. The only factor associated with a high rate of reoperation for site-specific recurrence was youth (<35 years). Gender, duration of symptoms, smoking habits, preoperative steroids therapy, preoperative albumin level, intra-abdominal abscess at laparotomy, number or length of strictureplasties, or previous or synchronous small bowel resection did not affect the reoperation rate. CONCLUSIONS Strictureplasty is a safe and efficacious procedure for jejunoileal Crohn's disease in the long term. Recurrence tends to develop early after strictureplasty, and late recurrence is uncommon. Only youth was a significant risk factor for site-specific recurrence requiring reoperation.

Abstract
Despite recent advances in the medical therapy of Crohn's disease, surgery continues to play a central role in the treatment of the disease. The strategy for surgical management of Crohn's disease continues to evolve. This chapter reviews many of the controversies surrounding surgical palliation of complications of Crohn's disease. Included is a discussion of indications for strictureplasty in treatment of intractable intestinal obstruction. Factors influencing long-term outcome with sphincter-saving resection in the treatment of Crohn's colitis are reviewed. Experience with definitive treatment of anal Crohn's disease and repair of rectovaginal fistulas is examined. Finally, recent experience supporting ileocolic resection when acute Crohn's ileitis is identified during laparotomy for right lower quadrant pain is critically evaluated. These controversial aspects of the surgical treatment of Crohn's disease reflect an improved understanding of the natural history of the disease as well as refinement in surgical techniques and better definition of criteria for surgical intervention.

Abstract
BACKGROUND Surgery for Crohn's disease is not intended for cure, but rather to relieve symptoms and treat complications. Perioperative morbidity, the fear of creating short bowel syndrome, and the tendency of the disease to recur convinced many physicians to refer their Crohn's patients for surgery only when life-threatening complications occur. METHODS This is a retrospective analysis of 47 patients operated on for Crohn's disease between 1989 and 1994. Twenty-six patients were operated on for "classic" indications ("classic" group) and the other 21 were operated on to improve their quality of life ("quality" group). RESULTS There was no operative or postoperative mortality during a mean follow-up period of 50 (27 to 84) months. All major postoperative complications occurred only in patients operated on for the classic indications (four abscesses, two fistulas, one wound dehiscence, and two small bowel obstructions). During the follow-up period, a total of 13 patients (50%) in the classic group and only 5 patients (24%) in the quality group required reintroduction of medical therapy or additional operations for exacerbations and complications of Crohn's disease. CONCLUSIONS Our data suggest that surgical intervention intended to improve the quality of life for Crohn's disease patients is safe and effective for carefully selected patients. It does improve quality of life, may prevent life-threatening complications, and offers a lower recurrence rate following surgery.

Abstract
The occurrence of small-bowel cancer in Crohn's disease (CD) is a rare event. The risk seems to be greatest in patients with long-standing disease. Strictureplasty has proved to be a valuable alternative in the management of Crohn's strictures of the small-bowel. Critics and proponents of strictureplasty for selected patients with small-bowel Crohn's disease have voiced their concerns about cancer risk in the strictured or strictureplasty site. To date, there has been no clear or detailed report of such an occurrence. The authors report the first case of small-bowel adenocarcinoma arising at the site of a previous strictureplasty. In this patient, biopsies of the strictures at the original operation confirmed CD and excluded both cancer and dysplasia. Malignancy occurred seven years later at a strictureplasty site. The main clinical sign associated with the adenocarcinoma was severe, persistent anemia. The authors conclude that the risk of adenocarcinoma developing at the site of a previous strictureplasty for CD, although small, is real.

Abstract
OBJECTIVE The authors' aim was to review the clinical features and estimate the long-term survival of patients with colorectal carcinoma complicating Crohn's disease. SUMMARY BACKGROUND DATA Recent studies have demonstrated a significantly increased risk of colorectal carcinoma in patients with Crohns disease. METHODS The authors reviewed retrospectively the medical records of 30 patients with Crohn's disease admitted to The Mount Sinai Hospital between 1960 and 1989 in whom colorectal adenocarcinoma developed. All patients were operated on and follow-up was complete for all patients to 10 years after operation, to the time of death, or to the closing date of the study in December 1989. RESULTS The 30 patients in the series had 33 colorectal adenocarcinomas; three patients (10%) presented with two synchronous cancers. The patients were relatively young (mean age, 53 years) and had long-standing Crohn's disease (duration >20 years in 87%). The 5-year actuarial survival was 44% for the overall series: 100% for stage A, 86% for stage B, 60% for stage C. All five patients with excluded bowel tumor died of large bowel cancer within 2.4 years; by contrast, the actuarial 5-year survival for patients with in-continuity tumors was 56%. CONCLUSIONS The incidence, characteristics, and prognosis of colorectal carcinoma complicating Crohn's disease are similar to the features of cancer in ulcerative colitis, including young age, multiple neoplasms, long duration of disease, and greater than a 50% 5-year survival rate (without excluded loops). These observations suggest the advisability of surveillance programs for Crohn's disease of the colon similar to those for ulcerative colitis of comparable duration and extent.

Abstract
An increased incidence of carcinoma of the small bowel and colon has been described in patients with Crohn's disease. Tumours arising in the rectum and anus are reported less often. Between 1940 and 1992, of some 2500 patients with Crohn's disease seen at this hospital, 15 are known to have developed carcinoma of the lower gastrointestinal tract. Malignancy occurred in the colon in two patients, in the upper two thirds of rectum in one, in the lower third of rectum in seven, and in the anus in five. The 12 patients with carcinoma arising in the anus or lower rectum had longstanding severe anorectal Crohn's disease, which included a stricture in four, fistula in four, proctitis in one, abscess in two, and enlarged anal skin tags in one. The development of malignancy in patients with Crohn's disease may apply particularly to those with chronic complicated anorectal disease.

Abstract
The clinical course of 44 patients undergoing elective proximal fecal diversion for Crohn's disease of the colon is reported. Sustained disease remission was obtained in 31 patients (70 percent). Diversion was associated with a significant reduction in steroid requirements (P < 0.01) and a significant improvement in hemoglobin (P < 0.001), erythrocyte sedimentation rate (P < 0.001), and albumin (P < 0.05). Sixteen patients (36.4 percent) have required a proctocolectomy, 19 patients (43.2 percent) remain defunctioned, and four patients (9 percent) have died. Five patients have had intestinal continuity restored, which has remained intact in four patients for a mean follow-up of 99 (range 21-153) months. Fecal diversion for Crohn's disease of the colon produces a high incidence of sustained disease remission, but for the majority of patients the prospect of future restoration of intestinal continuity is limited.

Abstract
We report on 14 cases of intestinal adenocarcinoma complicating Crohn's disease, seven occurring in the small bowel and seven in the large bowel. In both locations, two-thirds of patients were male. The average ages at the time of diagnosis of Crohn's disease and of cancer were similar between the two groups of patients: 28 and 48 years, respectively. The diagnosis of cancer was suspected or obtained preoperatively in only four cases of large bowel cancer; in two patients with large bowel cancer and five with small bowel cancer, the diagnosis was made at laparotomy. In the remaining cases, only careful histologic examination revealed the carcinoma. Six small bowel cancers were located in the ileum, and five colonic cancers were distal to the splenic flexure. Two small bowel and one large bowel cancer were multifocal and had surrounding mucosal dysplasia. All tumors, except one small bowel cancer, underwent resection. Survival correlated with stage of tumor at resection; no patient with regional or distant metastasis survived five years, in comparison with an 83 percent five-year actuarial survival rate of patients with tumor confined to the intestinal wall. Mean survival was six months for patients with small bowel cancer in comparison with 65 months for patients with large bowel cancer, reflecting a tendency toward more advanced lesions in the small bowel cancer group.

Abstract
Because Crohn's disease of the small bowel is often diffuse, strictureplasty has been advocated as an alternative or adjunct to resection(s) of strictured segments. We reviewed 116 patients with obstructive Crohn's disease undergoing 452 primary strictureplasties (Heineke-Mikulicz, 405; Finney, 47). The median age was 34 years (range, 13-72 years); the male-to-female ratio 1.4:1; and the median follow-up was three years (range, six months to seven years). Seventy-six patients (66 percent) had at least one previous small bowel resection. Perforative disease was present in 18 patients (15 percent), and synchronous resections were performed in 71 patients (61 percent). The median number of strictureplasties was three (range, 1-15). There was no mortality. Septic complications (intra-abdominal abscess/fistula) occurred in seven patients (6 percent), and reoperation for sepsis was needed in two patients. Relief of obstructive symptoms was achieved in 99 percent of the patients. After surgery, the median weight gain was 4 kg, and two-thirds of the patients were weaned off steroids. Symptomatic recurrence occurred in 28 patients (24 percent), and 17 patients (15 percent) needed reoperation. Rates of restricture and new stricture/perforative disease were 2.8 percent and 24 percent, respectively.
