Pal P, Reddy DN. Interventional endoscopy in inflammatory bowel disease: a comprehensive review. Gastroenterol Rep (Oxf) 2024; 12:goae075. [PMID: 39055373 PMCID: PMC11272179 DOI: 10.1093/gastro/goae075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Revised: 07/03/2024] [Accepted: 07/11/2024] [Indexed: 07/27/2024] Open
Abstract
Interventional endoscopy can play a key role in the multidisciplinary management of complex inflammatory bowel disease (IBD) as an adjunct to medical and surgical therapy. The primary role of interventional IBD (IIBD) includes the treatment of Crohn's disease-related stricture, fistula, and abscess. Endoscopic balloon dilation (EBD), endoscopic stricturotomy, and placement of endoscopic stents are different forms of endoscopic stricture therapy. EBD is the most widely used therapy whereas endoscopic stricturotomy has higher long-term efficacy than EBD. Fully covered and partially covered self-expanding metal stents are useful in long and refractory strictures whereas lumen-apposing metal stents can be used in short, and anastomotic strictures. Endoscopic fistula/abscess therapy includes endoscopic fistulotomy, seton placement, endoscopic ultrasound-guided drainage of rectal/pelvic abscess, and endoscopic injection of filling agents (fistula plug/glue/stem cell). Endoscopic seton placement and fistulotomy are mainly feasible in short, superficial, single tract fistula and in those with prior surgical seton placement. Similarly, endoscopic fistulotomy is usually feasible in short, superficial, single-tract fistula. Endoscopic closure therapies like over-the-scope clips, suturing, and self-expanding metal stent should be avoided for de novo/bowel to hollow organ fistulas. Other indications include management of postoperative complications in IBD such as management of surgical leaks and complications of pouchitis in ulcerative colitis. Additional indications include endoscopic resection of ulcerative colitis-associated neoplasia (by endoscopic mucosal resection, endoscopic submucosal dissection, and endoscopic full-thickness resection), retrieval of retained capsule endoscope, and control of bleeding. IIBD therapies can potentially act as a bridge between medical and surgical therapy for properly selected IBD patients.

Abstract
Acute or chronic anastomotic leak is a common complication after any gastrointestinal surgery in inflammatory bowel disease (IBD). The underlying disease of the bowel, comorbidities, malnutrition, anemia, and concurrent use of corticosteroids increase the risk for the development of anastomotic leaks. Anastomotic leak is traditionally managed with surgery. However, recent innovation has allowed the use of endoscopic methods in the management of some anastomotic leaks and their consequences. This article discusses a variety of endoscopic techniques that have either been established or are under current evaluation, for the management of anastomotic leaks in patients with IBD.

Abstract
Interventional inflammatory bowel disease (IBD) or endoscopic therapy for IBD or IBD surgery-associated complications has emerged as a main treatment modality bridging medical and surgical treatment. It delivers therapy more definitive than medical therapy and less invasive than surgical treatment. The main applications of interventional IBD are strictures, fistulas, abscesses, bleeding, foreign bodies, postoperative complications, and colitis-associated neoplasia. The major endoscopic treatment modalities are balloon dilation, stricturotomy, strictureplasty, fistulotomy, sinusotomy, septectomy, banding ligation, incision and drainage, polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection.

Abstract
Endoscopic therapy for inflammatory bowel diseases (IBD) or IBD surgery-associated complications or namely interventional IBD has become the main treatment modality for Crohn’s disease, bridging medical and surgical treatments. Currently, the main applications of interventional IBD are (i) strictures; (ii) fistulas and abscesses; (iii) bleeding lesions, bezoars, foreign bodies, and polyps; (iv) post-operative complications such as acute and chronic anastomotic leaks; and (v) colitis-associated neoplasia. The endoscopic treatment modalities include balloon dilation, stricturotomy, strictureplasty, fistulotomy, incision and drainage (of fistula and abscess), sinusotomy, septectomy, banding ligation, clipping, polypectomy, endoscopic mucosal resection, and endoscopic submucosal dissection. The field of interventional IBD is evolving with a better understanding of the underlying disease process, advances in endoscopic technology, and interest and proper training of next-generation IBD interventionalists.

Abstract
Ileal pouch-anal anastomosis (IPAA) or "J"-pouch as it is commonly referred to, is the treatment of choice in patients with medically refractory ulcerative colitis. IPAA can have infectious, inflammatory, and mechanical complications. Currently, there are no Food and Drug Administration-approved medical therapies for these complications. Surgery that may be eventually required can have significant morbidities due to the complexity of IPAA. Endoscopy is fast emerging as a leading modality of treatment for some of these pouch complications. Endoscopy in adjunct with medical treatment can help manage the majority of pouch-related disorders and improve the outcome.

Abstract
Ulcerative colitis (UC) is an autoimmune-mediated colitis which can present in varying degrees of severity and increases the individual’s risk of developing colon cancer. While first-line treatment for UC is medical management, surgical treatment may be necessary in up to 25–30% of patients. With an increasing armamentarium of biologic therapies, patients are presenting for surgery much later in their course, and careful understanding of the complex interplay of the disease, its management, and the patient’s overall health is necessary when considering he appropriate way in which to address their disease surgically. Surgery is generally a total proctocolectomy either with pelvic pouch reconstruction or permanent ileostomy; however, this may need to be spread across multiple procedures given the complexity of the surgery weighed against the overall state of the patient’s health. Minimally invasive surgery, employing either laparoscopic, robotic, or transanal laparoscopic approaches, is currently the preferred approach in the elective setting. There is also some emerging evidence that appendectomy may delay the progression of UC in some individuals. Those who treat these patients surgically must also be familiar with the numerous potential pitfalls of surgical intervention and have plans in place for managing problems such as pouchitis, cuffitis, and anastomotic complications.

Abstract
Backgrounds Endoscopic stricturotomy (ESt) has been shown to be effective in treating inflammatory bowel disease (IBD)-associated anastomotic strictures. However, the outcome of ESt in benign, non-IBD conditions has not been described. The aim of this study was to evaluate the outcome of ESt in the management of IBD and non-IBD-associated strictures. Methods Data of all consecutive IBD and non-IBD patients with benign anastomotic strictures treated with ESt from 2009 to 2016 were extracted. The primary outcomes were surgery-free survival and procedure-related complications. Results A total of 49 IBD and 15 non-IBD patients were included in this study. The IBD group included 25 patients with Crohn’s disease and 24 with ulcerative colitis and ileal pouches. Underlying diseases in the non-IBD group included colorectal cancer (n = 7), diverticulitis (n = 5), large bowel prolapse (n = 2), and constipation (n = 1). Immediate technical success was achieved in all patients in both groups. Bleeding complications occurred on five occasions (4.7% per procedure) in the IBD group, while no complication occurred in the non-IBD group (P = 0.20). Stricture improvement on follow-up endoscopy was found in 10 (20.4%) and 5 (33.3%) patients in the IBD and non-IBD groups, respectively (P = 0.32). Six (12.2%) patients in the IBD group and four (26.7%) patients in the non-IBD group eventually required stricture-related surgery (P = 0.23). IBD patients appeared to have a higher tendency for maintaining surgery-free after the procedure than non-IBD patients (P = 0.08). Conclusions Endoscopic stricturotomy was shown to have comparable outcomes, though non-IBD patients seem to have a higher need for subsequent surgery but a lower complication rate than IBD patients.

Abstract
Patients who undergo restorative protocolectomy with ileal pouch-anal anastomosis may develop mechanical complications such as presacral sinuses and fistulas. The current method of treatment may include medical therapy or redo surgery. Recently, endoscopic management for postoperative complications has shown effective results. We present a unique case of a pouch-to-pouch fistula, from the tip of the "J" to the anastomosis that was successfully treated with endoscopic needle-knife sinusotomy and over-the-scope clips.

Abstract
Interventional (or therapeutic) inflammatory bowel disease (IBD) endoscopy has an expanding role in the treatment of disease and surgical adverse events. Endoscopic therapy has been explored and used in the management of strictures, fistulas/abscesses, colitis-associated neoplasia, postsurgical acute or chronic leaks, and obstructions. The endoscopic therapeutic modalities include balloon dilation, stricturotomy, stent placement, fistulotomy, fistula injection and clipping, sinusotomy, EMR, and endoscopic submucosal dissection. With a better understanding of the disease course of IBD, improved long-term impact of medical therapy, and advances in endoscopic technology, we can foresee interventional IBD becoming an integrated part of the multidisciplinary approach to patients with complex IBD.

Abstract
BACKGROUND AND AIMS Pouch sinus may be a serious adverse event in patients undergoing ileal pouch-anal anastomosis. The aim of this study was to compare endoscopic sinusotomy (ESi) and redo pouch surgery in the management of pouch sinus. METHODS All consecutive ulcerative colitis patients with chronic pouch sinuses treated with ESi versus redo surgery from 2006 to 2016 were identified. The primary outcomes were recurrence-free and surgery-free survivals. The secondary outcome was postprocedural adverse events. RESULTS This historical cohort study included 226 patients (ESi, n = 141; redo surgery, n = 85). Complete healing of the sinus was achieved in 75 patients (53.2%) and partial healing in 23 patients (16.3%) with ESi, and an initial complete healing (ie, no anastomotic leak before ileostomy closure) was obtained in 80 patients (94.1%) receiving redo surgery. Sinus recurrence after complete healing was seen in 17 patients (22.7%) treated with ESi and 28 patients (32.9%) treated with surgery (P = .15). Subsequent surgery was needed in 34 patients (24.1%) with ESi therapy and 18 patients (21.2%) with initial redo surgery (P = .70). Kaplan-Meier recurrence-free and surgery-free survivals after initial procedures showed no statistical difference between the 2 groups (P = .42 and P = .65, respectively). The rate of adverse events in the ESi group was significantly lower than that in the surgery group (2.5% vs 43.5%, P < .0001). CONCLUSIONS Recurrence-free and surgery-free survivals were comparable between patients treated with ESi and redo surgery, whereas pouch redo surgery was found to be associated with a higher immediate complete healing rate yet a higher morbidity.

Abstract
BACKGROUND AND AIMS Pouch sinus is a serious complication in patients undergoing ileal pouch-anal anastomosis. The aim of this study was to verify the efficacy and safety of endoscopic needle knife sinusotomy (NKSi) in the management of pouch sinus. METHODS All consecutive patients with a pouch sinus treated with NKSi from 2008 to 2016 were identified. The primary outcomes were complete healing of the sinus and pouch survival. RESULTS A total of 109 patients were included. During a median follow-up of 2.1 years (interquartile range: 0.7-4.4), 54 (49.5%) patients achieved complete healing and 20 (18.3%) patients had partial healing, Twenty-two (20.2%) patients developed sinus-related pouch failure. In multivariable analysis for the sinus healing, Crohn's disease of the pouch was a risk factor [odds ratio (OR): 0.3, 95% confidence interval (CI): 0.1-0.8), whereas a longer interval between NKSi (OR: 1.1, 95%CI: 1.0-1.1) and high body mass index (OR: 1.2, 95%CI: 1.0-1.3) were protective factors. In the multivariable analysis for surgery-free survival, previously documented acute anastomotic leak (OR:3.5, 95%CI: 1.2-10.4), toxic megacolon (OR: 7.4, 95%CI: 1.9-29.1), an increased length of sinus (OR: 1.4, 95%CI: 1.0-2.0), and increased duration from sinus diagnosis to NKSi (OR: 2.6, 95%CI: 1.1-6.2) were risk factors; and a longer interval between NKSis (OR: 0.9, 95%CI: 0.9-0.99), and concurrent use of dextrose 50% (OR: 0.2, 95%CI: 0.04-0.6) and doxycycline during the NKSi procedure (OR: 0.2, 95%CI: 0.04-0.7) were protective factors. NKSi-associated complications were reported in 6 (1.8% per procedure) cases. CONCLUSIONS NKSi is an effective and safe procedure for treating pouch sinus.

Abstract
Inflammatory bowel disease (IBD) has been traditionally managed by IBD medical doctors or IBDologists and colorectal surgeons. Complications related to IBD and IBD surgery, such as stricture, fistula, and abscess, are common. For the past decade, endoscopic therapy has emerged as a valid treatment option for those complications. Endoscopic therapy provides more effective therapy for those structural complications than medical treatment, while being a less invasive approach than surgery. Endoscopic therapy plays a growing role in bridging medical and surgical therapies and is becoming an important component in the multidisciplinary approach to complex IBD. In fact, endoscopic therapy has become the treatment of choice for anastomotic stricture and anastomotic sinus. The role of endoscopic resection of colitis-associated neoplasia is currently being explored. Interventional IBD is intellectually and technically challenging. We are calling for proper teaching and training of our next generation of IBD interventionists.

Abstract
Restorative proctocolectomy with an ileoanal pouch anastomosis (IAPA) is the surgical therapy of choice for patients with refractory ulcerative colitis and/or associated (pre)neoplastic lesions. It is predominantly performed laparoscopically. Reconstruction with a J‑pouch is the most frequently applied variant due to the ideal combination of technical simplicity and good long-term results. In the present review, potential postoperative pouch complications, their risk factors, diagnostics and surgical management, as well as mid-term and long-term quality of life after pouch construction are differentially presented based on the current literature.

Abstract
Fistula and abscess represent penetrating disease phenotypes of Crohn's disease (CD) and can develop in patients with or without prior history of CD-related surgery. While CD fistula and abscess have been traditionally treated with medical and surgical therapy, the role of endoscopic therapy in this particular phenotype of CD is expanding recently, thanks to advanced endoscopic techniques and a better understanding of pathogenesis and natural history of the disease and principle of treatment. The success of endoscopic treatment for inflammatory bowel disease depends on comprehension and appreciation of principles, then techniques, followed by instrument and device. Attempts should be made to temporarily or permanently close the feeding side (or the primary) orifice at the gut, by various forms of clipping. Endoscopic fistulotomy is feasible, particularly for perianal fistula and surgery-associated distal bowel fistula. Perianal abscess can be treated with endoscopic incision and drainage and even seton placement. Endoscopic treatment for fistula and abscess as well as for stricture has become an important part of the multidisciplinary approach to complex CD.

Patients may develop fistulas due to Crohn’s disease or as a postoperative complication after restorative proctocolectomy with ileal pouch anal anastomosis. Unfortunately, the treatment of fistulas can be challenging. The current standard of care may include medical therapy and/or surgical intervention. However, endoscopic treatment for postoperative pouch complications has emerged as a valid alternative option. We describe a case of persistent drainage from a Y-shaped entero-entero-cutaneous fistula that resolved after endoscopic fistulotomy with needle knife.

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

Abstract
BACKGROUND AND AIMS The impact of gender on the development of chronic ileal pouch disorders following ileal pouch-anal anastomosis (IPAA) has not been evaluated. This study was aimed to assess the association between gender and pouch outcomes. METHODS Comparisons of long-term pouch outcomes between male and female patients were performed using both univariate and multivariate analyses. RESULTS Of all patients enrolled (n = 1564), 881(56.3 %) were males. Male patients were older at the time of inflammatory bowel disease (IBD) diagnosis and pouch construction. The frequencies of neoplasia as the indication for colectomy and significant comorbidity were higher in males, while fewer male patients had IBD-related extra-intestinal manifestations or concurrent autoimmune disorders. There was no significant difference between the genders in other clinicopathological characteristics. More male patients (n = 144, 16.3 %) developed chronic antibiotic-refractory pouchitis (CARP) than females (n = 73, 10.7 %) (P = 0.001). Seventy-four males (8.4 %) had ileal pouch anastomotic sinus versus 22 female patients (3.2 %) (P < 0.001). Multivariate logistic regression analyses confirmed the association between male gender and CARP (odds ratio (OR) 1.64, 95 % confidence interval (CI) 1.21-2.24, P = 0.002) and male gender and ileal pouch anastomotic sinus (OR 2.85, 95 % CI 1.48-5.47, P = 0.002). After a median follow-up of 9.0 (interquartile range 4.0-14.0) years, pouch failed in a total of 126 patients (8.1 %). No significant difference was identified between male and female patients in pouch failure (P = 0.61). CONCLUSIONS Among the pouch patients referred to our subspecialty Pouch Center, male patients were found to have an increased risk for the CARP and ileal pouch sinus. The pathogenic mechanisms of the association warrant further study.

Abstract
PURPOSE OF REVIEW Restorative proctocolectomy with ileal pouch-anal anastomosis is the surgical treatment of choice for patients with ulcerative colitis or familial adenomatous polyposis who require colectomy. Although the surgical procedure significantly improves the patients' quality of life, complications are common. Mechanical or structural complications related to surgical techniques as well as chronic pouchitis are common after the procedure. RECENT FINDINGS Recent literature has suggested some of those mechanical complications, along with chronic pouchitis, may share similar risk factors, particularly between anastomotic leak or sinus and chronic pouchitis. Those factors include male gender, obesity, weight gain, and Clostridium difficile infection. SUMMARY Mounting clinical evidence suggests that ischemia or excessive fat deposition plays an important role in the development of the surgical procedure-associated mechanical complication as well as chronic antibiotic-refractory pouchitis. Those findings along with the theory of ischemia/fat deposition will shed some light on the pathogenesis of the complex pouch disorders, providing the guidance for the risk stratification, prevention, diagnosis, and management.

Abstract
Stricture and fistula are common complications of Crohn's disease. Endoscopic balloon dilation and needle-knife stricturotomy has become a valid treatment option for Crohn's disease-associated strictures. Endoscopic therapy is also increasingly used in Crohn's disease-associated fistula. Preprocedural preparations, including routine laboratory testing, imaging examination, anticoagulant management, bowel cleansing and proper sedation, are essential to ensure a successful and safe endoscopic therapy. Adverse events, such as perforation and excessive bleeding, may occur during endoscopic intervention. The endoscopist should be well trained, always be cautious, anticipate for possible procedure-associated complications, be prepared for damage control during endoscopy, and have surgical backup ready. In this review, we discuss the principle, preparation, techniques of endoscopic therapy, as well as the prevention and management of endoscopic procedure-associated complications. We propose that inflammatory bowel disease endoscopy may be a part of training for "super" gastroenterology fellows, i.e., those seeking a career in advanced endoscopy or in inflammatory bowel disease.

Abstract
Ileal pouch-anal anastomosis surgery can be complicated by anastomotic leaks, leading to the formation of abscess and chronic sinus that have been routinely managed by a surgical approach. We developed the endoscopic needle knife sinusotomy (NKSi) technique, which has become a valid alternative. The basic principle of endoscopic NKSi is dissection and drainage of the sinus through its orifice internally into the lumen of pouch body. The success of NKSi requires an access to the sinus from the pouch side. One of the most challenging situations for NKSi is a closed orifice of the sinus, which leaves an isolated chronic abscess cavity. Here we report a case of complicated presacral sinus with a closed orifice that was not amenable to NKSi, necessitating a CT-guided guide wire placement and subsequent NKSi.

Abstract
Patients with inflammatory bowel diseases often undergo surgical procedures for medically refractory disease or colitis associated dysplasia. Endoscopic evaluation of the surgically altered bowel is often needed to assess for disease recurrence, its severity, and for therapy. It is important to obtain and review the operative report and abdominal imaging before performing the endoscopy. Diagnostic and therapeutic endoscopy can be safely performed in most patients with inflammatory bowel disease with altered bowel anatomy under conscious sedation without fluoroscopy. Carefully planned stricture therapy with balloon dilation or needle knife stricturotomy can be performed for simple, short, and fibrotic strictures. A multidisciplinary approach involving a team of endoscopist, endoscopy nurse, colorectal surgeon, gastrointestinal pathologist, and gastrointestinal radiologist is important for a safe and effective endoscopy. We attempt to review the aspects that need consideration before the endoscopy, the technique of endoscopy, and briefly the therapies that can be performed during endoscopy of the bowel through an ileostomy, a colostomy, in the diverted large bowel or ileal pouch, and small bowel after stricturoplasty and bowel bypass surgery in patients with inflammatory bowel diseases.

Abstract
Endoscopy plays a key role in the diagnosis and treatment of patients with inflammatory bowel disease (IBD). Colonoscopy has been traditionally used in the diagnosis of IBD and helps in determination of an important end point in patient management, “mucosal healing”. However, the involvement of an advanced endoscopist has expanded with innovations in therapeutic and newer imaging techniques. Endoscopists are increasingly being involved in the management of anastomotic and small bowel strictures in these patients. The advent of balloon enteroscopy has helped us access areas not deemed possible in the past for dilations. An advanced endoscopist also plays an integral part in managing ileal pouch-anal anastomosis complications including management of pouch strictures and sinuses. The use of rectal endoscopic ultrasound has been expanded for imaging of perianal fistulae in patients with Crohn’s disease and appears much more sensitive than magnetic resonance imaging and exam under anesthesia. Advanced endoscopists also play an integral part in detection of dysplasia by employing advanced imaging techniques. In fact the paradigm for neoplasia surveillance in IBD is rapidly evolving with advancements in endoscopic imaging technology with pancolonic chromoendoscopy becoming the main imaging modality for neoplasia surveillance in IBD patients in most institutions. Advanced endoscopists are also called upon to diagnose primary sclerosing cholangitis (PSC) and also offer options for endoscopic management of strictures through endoscopic retrograde cholangiopancreatography (ERCP). In addition, PSC patients are at increased risk of developing cholangiocarcinoma with a 20% lifetime risk. Brush cytology obtained during ERCP and use of fluorescence in situ hybridization which assesses the presence of chromosomal aneuploidy (abnormality in chromosome number) are established initial diagnostic techniques in the investigation of patients with biliary strictures. Thus advanced endoscopists play an integral part in the management of IBD patients and our article aims to summarize the current evidence which supports this role and calls for developing and training a new breed of interventionalists who specialize in the management of IBD patients and complications specific to those patients.
