Abstract
BACKGROUND Radiographic imaging of the abdomen and pelvis plays an important role in the diagnosis and management of ileal pouch disorders with modalities including CT, MRI, contrasted pouchography, and defecography. OBJECTIVES To perform a systematic review of the literature and describe applications of cross-sectional imaging, pouchography, defecography, and ultrasonography. DATA SOURCES PubMed, Google Scholar, and Cochrane database. STUDY SELECTION Relevant articles on endoscopy in ileal pouches published between January 2003 and June 2023 in English were included on the basis of Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. INTERVENTION Main abdominal and pelvic imaging modalities and their applications in the diagnosis of ileal pouch disorders were included. MAIN OUTCOME MEASURES Accuracy in characterization of ileal pouch disorders. RESULTS CT is the test of choice for the evaluation of acute anastomotic leaks, perforation, and abscess(es). MRI of the pelvis is suitable for the assessment of chronic anastomotic leaks and their associated fistulas and sinus tracts, as well as for the penetrating phenotype of Crohn's disease of the pouch. CT enterography and magnetic resonance enterography are useful in assessing intraluminal, intramural, and extraluminal disease processes of the pouch and prepouch ileum. Water-soluble contrast pouchography is particularly useful for evaluating acute or chronic anastomotic leaks and outlines the shape and configuration of the pouch. Defecography is the key modality to evaluate structural and functional pouch inlet and outlet obstructions. Ultrasonography can be performed to assess the pouch in experienced IBD centers. LIMITATIONS This is a qualitative, not quantitative, review of mainly case series and case reports. CONCLUSIONS Abdominopelvic imaging, along with clinical and endoscopic evaluation, is imperative for accurately assessing structural, inflammatory, functional, and neoplastic disorders.

Abstract
BACKGROUND Structural and inflammatory adverse sequelae are common after restorative proctocolectomy and IPAA. On rare occasions, neoplasia can occur in patients with ileal pouches. Pouchoscopy plays a key role in the diagnosis, differential diagnosis, disease monitoring, assessment of treatment response, surveillance, and delivery of therapy. OBJECTIVE A systematic review of the literature was performed, and principles and techniques of pouchoscopy were described. DATA SOURCES PubMed, Google Scholar, and Cochrane databases. STUDY SELECTION Relevant articles on endoscopy in ileal pouches published between January 2000 and May 2023 were included based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. INTERVENTION Diagnostic, surveillance, and therapeutic endoscopy in ileal pouch disorders were included. MAIN OUTCOME MEASURES Accurate characterization of the ileal pouch in healthy or diseased states. RESULTS The main anatomic structures of a J- or S-pouch are the stoma closure site, prepouch ileum, inlet, tip of the "J," pouch body, anastomosis, cuff, and anal transition zone. Each anatomic location can be prone to the development of structural, inflammatory, or neoplastic disorders. For example, ulcers and strictures are common at the stoma closure site, inlet, and anastomosis. Leaks are commonly detected at the tip of the "J" and anastomosis. Characterization of the anastomotic distribution of inflammation is critical for the differential diagnosis of subtypes of pouchitis and other inflammatory disorders of the pouch. Neoplastic lesions, albeit rare, mainly occur at the cuff, anal transition zone, or anastomosis. LIMITATIONS This is a qualitative, not quantitative, review of mainly case series. CONCLUSIONS Most structural, inflammatory, and neoplastic disorders can be reliably diagnosed with a careful pouchoscopy. The endoscopist and other clinicians taking care of pouch patients should be familiar with the anatomy of the ileal pouch and be able to recognize common abnormalities. See video from symposium.

Abstract
Ileal pouch-anal anastomosis (IPAA) is the procedure of choice for reconstruction after total proctocolectomy in pediatric patients with ulcerative colitis. 30-60 % of patients undergoing IPAA will experience a postoperative complication. The primary objective of this article is to address the most common complications specific to IPAA in the pediatric population and provide an up-to-date review of their presentation, risk factors, workup, and management. We also share our preferred approaches to management and prevention of complications, where relevant. We intend to provide a concise review on the topic aimed at pediatric surgeons and healthcare providers involved in the care of this population with the goal of contributing to improved outcomes and patient quality of life.

Abstract
BACKGROUND Patients with ulcerative colitis refractory to medication or familial adenomatous polyposis may require ileal pouch-anal anastomosis after a colectomy. IPAA is generally well tolerated. However, patients can experience posttreatment complications, including pouch strictures and leaks. Medical therapy has a limited role in mechanical fibrotic strictures, whereas surgery is invasive and costly. In the past few decades, endoscopic therapies have provided a less invasive and less costly intervention for pouch strictures and leaks. OBJECTIVE This systematic literature review aimed to describe the status of advancements in endoscopic therapy for pouch leaks and strictures. DATA SOURCES The sources used were PubMed and Cochrane databases. STUDY SELECTION Studies between January 1990 and January 2022, in any language, were included. Articles regarding surgical management or pouches other than adult ileal pouch-anal anastomosis were excluded. INTERVENTIONS Endoscopic management of acute and chronic leaks and strictures ileal pouch-anal anastomosis was included. MAIN OUTCOME MEASURES Successful management (including persistent leak or stricture, pouch failure, subsequent endoscopy, or surgery) was measured. RESULTS Sixty-one studies were included in this review, including 4 meta-analyses or systematic reviews, 11 reviews, 17 cohort studies, and 18 case series. LIMITATIONS The limitations include qualitative review of all study types, with no randomized controlled studies available. CONCLUSION Ileal pouch-anal anastomosis leaks are various in configuration, and endoscopic therapies have included clipping leaks at the tip of the "J" as well as endoscopic sinusotomy. Endoscopic therapies for pouch strictures have included endoscopic balloon dilation, endoscopic stricturotomy, and endoscopic stricturoplasty, which are now considered first-line therapies for pouch strictures. Endoscopic balloon dilation has shown safety and efficacy in single, short, and straight strictures and endoscopic stricturotomy for refractory long, fibrotic, anastomotic strictures. Endoscopic therapies can delay or prevent invasive surgeries. Key tenets of successful endoscopic therapy include patient and lesion candidacy, an experienced endoscopist, and adequate rescue surgery plans.

Abstract
BACKGROUND Pouchitis is the most common inflammatory complication in ulcerative colitis patients undergoing postoperative construction of an IPAA. Pouchitis refers to a spectrum of diseases, and as such, it lacks a universally accepted definition as well as validated instruments to measure disease activity and treatment response. Assessing pouchitis activity is challenging, and methods for diagnosis and classification of severity of pouchitis are not universally agreed upon. CLINICAL FEATURES Pouchitis is characterized by a constellation of clinical symptoms, including increased stool frequency, urgency, incontinence, bleeding, and rarely constitutional symptoms such as malaise and low-grade fever. However, these symptoms are subjective, and similar symptoms can be caused by noninflammatory conditions including anal sphincter dysfunction, anastomotic strictures, occult leaks, pouch inlet obstruction, and cuffitis. Objective scores that include endoscopic and histologic criteria have been developed for subjects with an IPAA. However, these instruments are not validated for measuring pouchitis disease activity and are associated with a number of challenges. In addition, the clinical components of the scores correlate poorly with endoscopic and histologic findings. CONCLUSION AND FUTURE DIRECTIONS There is a need for prospective studies to facilitate the development and validation of novel instruments that are valid, reliable, and responsive to change that would facilitate the development of therapeutic agents for the treatment of pouchitis.

Abstract
BACKGROUND AND AIMS The diagnosis and follow up of patients with inflammatory bowel disease [IBD] requires cross-sectional imaging modalities, such as intestinal ultrasound [IUS], magnetic resonance imaging [MRI] and computed tomography [CT]. The quality and homogeneity of medical reporting are crucial to ensure effective communication between specialists and to improve patient care. The current topical review addresses optimized reporting requirements for cross-sectional imaging in IBD. METHODS An expert consensus panel consisting of gastroenterologists, radiologists and surgeons convened by the ECCO in collaboration with ESGAR performed a systematic literature review covering the reporting aspects of MRI, CT, IUS, endoanal ultrasonography and transperineal ultrasonography in IBD. Practice position statements were developed utilizing a Delphi methodology incorporating two consecutive rounds. Current practice positions were set when ≥80% of the participants agreed on a recommendation. RESULTS Twenty-five practice positions were developed, establishing standard terminology for optimal reporting in cross-sectional imaging. Assessment of inflammation, complications and imaging of perianal CD are outlined. The minimum requirements of a standardized report, including a list of essential reporting items, have been defined. CONCLUSIONS This topical review offers practice recommendations to optimize and homogenize reporting in cross-sectional imaging in IBD.

Abstract
This review summarizes the relevant literature for the selection of the initial imaging in 4 clinical scenarios in patients with suspected inflammatory disease or postoperative complication of the anorectum. These clinical scenarios include suspected perianal fistula or abscess; rectovesicular or rectovaginal fistula; proctitis or pouchitis; and suspected complication following proctectomy, coloproctectomy, or colectomy with a pouch or other anastomosis. The appropriateness of imaging modalities as they apply to each clinical scenario is rated as usually appropriate, may be appropriate, and usually not appropriate to assist the selection of the most appropriate imaging modality in the corresponding clinical scenarios of anorectal disease. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
BACKGROUND Megapouch is a rare functional complication of restorative proctocolectomy with ileal pouch-anal anastomosis characterized by pouch ± small bowel dilatation with no evidence of obstruction on endoscopy and imaging. Little is known about clinical characteristics and outcomes of this entity. METHODS We included all patients diagnosed with megapouch at our institution, identified from a pouch database. Data on baseline characteristics, management, and outcomes were documented and analyzed from electronic medical records. Appropriate statistical measures were used. p < 0.05 was considered significant. RESULTS Twenty-three patients with megapouch were identified. The mean age was 40.7 years; 95.6% had underlying ulcerative colitis; most common indication for colectomy was medically refractory disease (56.5%). Abdominal pain (82.6%) and bloating (52.2%) were most common presenting symptoms. Most common finding on pouchoscopy was pouch dilatation (81.8%), while barium or gastrografin enemas and MRI/CT mostly revealed dilatation of pouch and/or small bowel. Fourteen (66.7%) patients required some forms of surgery-six patients required pouch excision and three required either pouch redo or revision. Rates of pouch failure and IBD-related 1-year hospitalization were higher among patients managed surgically versus those managed medically (p = 0.007 and 0.024, respectively), while need for escalation of IBD-therapy was comparable between the groups (p = 0.133). No deaths were reported and no patient had recurrence of megapouch. IPAA revision or redo did not lead to more IBD-related morbidity. CONCLUSIONS Majority of our patients with megapouch required surgery. In selected patients, redo pouch offered cure. Rates of pouch failure and IBD-related 1-year hospitalization were higher among patients managed surgically.

Abstract
OBJECTIVES Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the "gold standard" procedure for patients with ulcerative colitis (UC) requiring surgical intervention. A de-functioning ileostomy is usually performed, as a step for the IPAA procedure. The aim of this study is to present the methodology and results of the routine double assessment of IPAA integrity in asymptomatic patients prior to the ileostomy reversal and evaluate its necessity. METHODS This is a retrospective study of 61 UC patients, who underwent IPAA construction, in 2010-2016. A diverting ileostomy was created after IPAA construction, which was reversed at least 3 months later. A double assessment, with pouchogram and pouchoscopy, of IPAA integrity was performed, before stoma closure. Post-operative symptoms and signs of complications, imaging studies, and endoscopic findings were recorded during follow-up. RESULTS Prior to the ileostomy reversal, both pouchoscopy and pouchogram identified no patient with evidence of anastomotic leakage. During a mean follow-up of 3.67 years after ileostomy reversal, 11 patients developed complications but only one had signs of leakage, which presented as a pouch-vaginal fistula. The specificity of both the pouchogram and pouchoscopy reached 100% and the negative predictive value ranged between 98.4 and 100%. CONCLUSIONS The specificity of pouchoscopy and pouchogram prior to ileostomy closure, in asymptomatic patients with IPAA for UC, is very high in recognizing an intact anastomosis, but their combination did not alter the diagnostic accuracy or had any effect in further management. At least, pouchogram could be selectively performed only in patients with high-risk clinical indicators. KEY POINTS • The double assessment of ileal pouch-anal anastomosis with pouchogram and pouchoscopy, prior to ileostomy closure, specifically in patients with ulcerative colitis has not been evaluated before. • The specificity of pouchoscopy and pouchogram prior to ileostomy closure, in asymptomatic patients with IPAA for UC, is very high in recognizing an intact anastomosis. • However, their combination did not alter the diagnostic accuracy or had any effect in further management, in asymptomatic patients.

Abstract
PURPOSE Variability in functional outcome after ileal pouch-anal anastomosis (IPAA) is to a large extent unexplained. The aim of this study was to use MRI to evaluate the morphology, emptying pattern and other pathology that may explain differences in functional outcome between well-functioning and poorly functioning pouch patients. A secondary aim was to establish a reference of normal MRI findings in pelvic pouch patients. METHODS From a previous study, the best and worst functioning patients undergoing IPAA surgery between 2000 and 2013 had been identified and examined with manovolumetric tests (N = 47). The patients were invited to do a pelvic MRI investigating pouch morphology and emptying patterns, followed by a pouch endoscopy. RESULTS Forty-three patients underwent MRI examination. We found no significant morphological or dynamic differences between the well-functioning and poorly functioning pouch patients. There was no correlation between urge volume and the volume of the bony pelvis, and no correlation between emptying difficulties or leakage and dynamic MRI findings. Morphological MRI signs of inflammation were present in the majority of patients and were not correlated to histological signs of inflammation. Of the radiological signs of inflammation, only pouch wall thickness correlated to endoscopic pouchitis disease activity index scores. CONCLUSION It seems MRI does not increase the understanding of factors contributing to functional outcome after ileal pouch-anal anastomosis. Unless there is a clinical suspicion of perianal/peripouch disease or pelvic sepsis, MRI does not add value as a diagnostic tool for pelvic pouch patients. Endoscopy remains the golden standard for diagnosing pouch inflammation.

Abstract
Restorative proctocolectomy with ileal-pouch anal anastomosis (IPAA) is the operation of choice for medically refractory ulcerative colitis (UC), for UC with dysplasia, and for familial adenomatous polyposis (FAP). IPAA can be a treatment option for selected patients with Crohn’s colitis without perianal and/or small bowel disease. The term “pouchitis” refers to nonspecific inflammation of the pouch and is a common complication in patients with IPAA; it occurs more often in UC patients than in FAP patients. This suggests that the pathogenetic background of UC may contribute significantly to the development of pouchitis. The symptoms of pouchitis are many, and can include increased bowel frequency, urgency, tenesmus, incontinence, nocturnal seepage, rectal bleeding, abdominal cramps, and pelvic discomfort. The diagnosis of pouchitis is based on the presence of symptoms together with endoscopic and histological evidence of inflammation of the pouch. However, “pouchitis” is a general term representing a wide spectrum of diseases and conditions, which can emerge in the pouch. Based on the etiology we can sub-divide pouchitis into 2 groups: idiopathic and secondary. In idiopathic pouchitis the etiology and pathogenesis are still unclear, while in secondary pouchitis there is an association with a specific causative or pathogenetic factor. Secondary pouchitis can occur in up to 30% of cases and can be classified as infectious, ischemic, non-steroidal anti-inflammatory drugs-induced, collagenous, autoimmune-associated, or Crohn’s disease. Sometimes, cuffitis or irritable pouch syndrome can be misdiagnosed as pouchitis. Furthermore, idiopathic pouchitis itself can be sub-classified into types based on the clinical pattern, presentation, and responsiveness to antibiotic treatment. Treatment differs among the various forms of pouchitis. Therefore, it is important to establish the correct diagnosis in order to select the appropriate treatment and further management. In this editorial, we present the spectrum of pouchitis and the specific features related to the diagnosis and treatment of the various forms.

Abstract
Radiographical modalities have become important diagnostic tools in cases of ulcerative colitis (UC). Imaging can be used non-invasively to determine the extent of involvement, severity of disease and to detect disease-related complications and extra-intestinal inflammatory bowel disease (IBD) manifestations. While abdominal X-rays and barium enemas still retain their relevance in specific clinical settings, the use of computed tomography enterography (CTE) or magnetic resonance enterography (MRE) are now used as first-line investigations to exclude active small bowel disease in IBD patients and can be utilized to detect active colonic inflammation. Additionally, CT colonography and MR colonography are emerging techniques with potential applications in UC. Ultrasonography, leukocyte scintigraphy and positron emission tomography are novel abdominal imaging modalities currently being explored for IBD interrogations. This plethora of radiological imaging options has become a vital component of UC assessments.

Outcomes of computed tomography and magnetic resonance enterography in clinical practice of inflammatory bowel disease. Dig Dis Sci 2014; 59:838-49. [PMID: 24323180 DOI: 10.1007/s10620-013-2964-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2013] [Accepted: 11/15/2013] [Indexed: 12/20/2022]
Abstract
BACKGROUND Computed tomography (CT) and magnetic resonance (MR) enterography are now widely used to diagnose and monitor Crohn's disease. AIM We sought to assess the use of enterography for management of inflammatory bowel disease (IBD) in our medical center. METHODS We performed a retrospective review of all patients diagnosed with IBD who underwent MR or CT enterography from November 1, 2010 to October 25, 2012 at our institution. We assessed disease complications identified by enterography, agreement between disease activity determined by endoscopy and enterography, association between inflammatory markers and enterography-determined disease activity and recommended changes in medical and surgical management following enterography. RESULTS A total of 311 enterography studies (291 MR and 20 CT enterographies) were performed on 270 patients, including 258 (83.0 %) on patients with presumed Crohn's disease and 53 (17.0 %) with presumed ulcerative colitis. Active small bowel (SB) disease was noted in 73/311 (23.5 %) studies. Complications including strictures, perianal fistulas, abscesses and SB fistulas were noted in 108/311 (34.7 %) studies. Endoscopic and enterography defined active disease had an agreement of κ = 0.36 in the ileum (n = 179). A total of 142/311 (45.7 %) enterographies were associated with recommended medication changes within 90 days while surgery or endoscopic dilation of stricture was recommended following 41/311 (13.2 %) enterographies. Enterography resulted in a change in diagnosis from ulcerative colitis to Crohn's in 5/311 (1.6 %) studies. CONCLUSION Enterography reveals active disease and complications not evident on endoscopy and should be considered in the initial diagnosis, assessment of disease activity, and monitoring of therapy in patients with IBD.

Abstract
Endoscopic therapies are important modalities in the treatment of IBD, adjunct to medical and surgical approaches. These therapeutic techniques are particularly useful in the management of IBD-associated or IBD surgery–associated strictures, fistulas, and sinuses and colitis-associated neoplasia. Although the main focus of endoscopic therapies in IBD has been on balloon stricture dilation and ablation of adenoma-like lesions, new endoscopic approaches are emerging, including needle-knife stricturotomy, needle-knife sinusotomy, endoscopic stent placement, and fistula tract injection. Risk management of endoscopy-associated adverse events is also evolving. The application of endoscopic techniques in novel ways in the treatment of IBD is just beginning and will likely expand rapidly in the near future.

Abstract
Pouchitis is the most common complication among patients with ulcerative colitis who have undergone restorative proctocolectomy with ileal pouch-anal anastomosis. Pouchitis is actually a spectrum of diseases that vary in etiology, pathogenesis, phenotype, and clinical course. Although initial acute episodes typically respond to antibiotic therapy, patients can become dependent on antibiotics or develop refractory disease. Many factors contribute to the course of refractory pouchitis, such as the use of nonsteroidal anti-inflammatory drugs, infection with Clostridium difficile, pouch ischemia, or concurrent immune-mediated disorders. Identification of these secondary factors can help direct therapy.

Abstract
Approximately 20%-30% of patients with ulcerative colitis will eventually require colectomy despite recent advances in medical therapy. Ileal pouch-anal anastomosis has become the surgical treatment of choice. A subset of patients with ileal pouches can develop Crohn's disease or a Crohn's-disease-like condition of the ileal pouch after surgery. Diagnosis, differential diagnosis, and management of Crohn's disease of the ileal pouch have been challenging. A combined assessment of clinical history, endoscopy, histology, abdominal/pelvic imaging, and examination under anesthesia is often necessary for accurate diagnosis, disease classification, management, and prognosis. A multidisciplinary approach with gastroenterologists, colorectal surgeons, gastrointestinal pathologists, and radiologists is advocated.

Abstract
BACKGROUND Anastomotic sinus is a relatively uncommon complication after an IPAA. Disease course is poorly defined, and management can be challenging. OBJECTIVE The purpose of this study was to evaluate the frequency, management, and outcome of anastomotic pouch sinus. DESIGN This research is a retrospective cohort study from a prospectively collected database. SETTING The investigation took place in a high-volume specialized colorectal surgery department. PATIENTS Patients with an anastomotic sinus after pouch surgery from 1997 to 2009 were included. MAIN OUTCOMES MEASURES The primary outcomes measured were sinus healing and pouch failure. RESULTS Of 2286 patients who underwent an IPAA, 45 (2.0%) patients were identified with an anastomotic pouch sinus. There were 32 (71%) males, and the mean age was 40 (±13) years. The pouch sinus was initially managed by observation in 23 (51%) patients, drainage of the sinus in 9 (20%) patients, unroofing of the sinus tract in 8 (18%) patients, sinus closure in 3 (7%) patients, and a diverting ileostomy in 2 (4%) patients. In 28 patients (62%), subsequent treatment was necessary. Sinus healing was achieved in 27 (60%) patients, whereas 15 (33%) eventually developed pouch failure. Of the treatment modalities applied, a strategy with observation as initial treatment was the most successful with a healing rate of 65%. The healing rate was significantly lower in symptomatic patients in comparison with asymptomatic patients (30% vs 84%, p = 0.001). Pouch failure was also higher (45% vs 24%, p = 0.14). No other factors associated with healing rate or pouch failure were identified. LIMITATIONS This study was limited by its nonrandomized retrospective design. CONCLUSION Anastomotic pouch sinuses after pouch surgery are associated with a high rate of pouch failure. Symptomatic presentation is a significant predictor for low healing rates and is associated with a high risk of pouch failure. Observation and watchful monitoring is the initial treatment of choice when permitted by the patient's condition.

Abstract
Although restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the surgical treatment of choice for patients with refractory ulcerative colitis (UC) or UC with dysplasia, surgical, inflammatory, and noninflammatory adverse sequelae are common. Pouchitis, representing a spectrum of disease phenotypes, is the most common long-term complication of IPAA. De novo Crohn disease (CD) of the pouch can occur in patients with a preoperative diagnosis of UC. Differential diagnosis between fibrostenotic or fistulizing CD and surgery-associated strictures, sinuses, and fistulas often requires a combined assessment of symptom, endoscopy, histology, radiography, and examination under anesthesia. There is a role for endoscopic therapy for stricturing complications of IPAA. Chronic antibiotic-refractory pouchitis, refractory cuffitis, as well as fibrostenotic or fistulizing CD of the pouch are the leading late-onset causes for pouch failure.
