Abstract
Large bowel obstruction is a serious event that occurs in approximately 25% of all intestinal obstructions. It is attributed to either benign, malignant, functional (pseudo-obstruction), or mechanical conditions. Benign etiologies of colonic obstructions include colon volvulus, anastomotic strictures, radiation injury, ischemia, inflammatory processes such as Crohn's disease, diverticulitis, bezoars, and intussusception.

Walayat S, Johannes AJ, Benson M, Nelsen E, Akhter A, Kennedy G, Soni A, Reichelderfer M, Pfau P, Gopal D. Outcomes of colon self–expandable metal stents for malignant vs benign indications at a tertiary care center and review of literature. World J Gastrointest Endosc 2023; 15:309-318. [PMID: 37138935 PMCID: PMC10150280 DOI: 10.4253/wjge.v15.i4.309] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 02/09/2023] [Accepted: 04/04/2023] [Indexed: 04/14/2023] Open
Abstract
BACKGROUND Endoscopic placement of a self-expandable metal stent (SEMS) is a minimally invasive treatment for use in malignant and benign colonic obstruction. However, their widespread use is still limited with a nationwide analysis showing only 5.4% of patients with colon obstruction undergoing stent placement. This underutilization could be due to perceived increase risk of complications with stent placement.
AIM To review long- and short-term clinical success of SEMS use for colonic obstruction at our center.
METHODS We retrospectively reviewed all the patients who underwent colonic SEMS placement over a eighteen year period (August 2004 through August 2022) at our academic center. Demographics including age, gender, indication (malignant and benign), technical success, clinical success, complications (perforation, stent migration), mortality, and outcomes were recorded.
RESULTS Sixty three patients underwent colon SEMS over an 18-year period. Fifty-five cases were for malignant indications, 8 were for benign conditions. The benign strictures included diverticular disease stricturing (n = 4), fistula closure (n = 2), extrinsic fibroid compression (n = 1), and ischemic stricture (n = 1). Forty-three of the malignant cases were due to intrinsic obstruction from primary or recurrent colon cancer; 12 were from extrinsic compression. Fifty-four strictures occurred on the left side, 3 occurred on the right and the rest in transverse colon. The total malignant case (n = 55) procedural success rate was 95% vs 100% for benign cases (P = 1.0, NS). Overall complication rate was significantly higher for benign group: Four complications were observed in the malignant group (stent migration, restenosis) vs 2 of 8 (25%) for benign obstruction (1-perforation, 1-stent migration) (P = 0.02). When stratifying complications of perforation and stent migration there was no significant difference between the two groups (P = 0.14, NS).
CONCLUSION Colon SEMS remains a worthwhile option for colonic obstruction related to malignancy and has a high procedural and clinical success rate. Benign indications for SEMS placement appear to have similar success to malignant. While there appears to be a higher overall complication rate in benign cases, our study is limited by sample size. When evaluating for perforation alone there does not appear to be any significant difference between the two groups. SEMS placement may be a practical option for indications other that malignant obstruction. Interventional endoscopists should be aware and discuss the risk for complications in setting of benign conditions. Indications in these cases should be discussed in a multi-disciplinary fashion with colorectal surgery.

Abstract
Background: Interventional inflammatory bowel disease (IIBD) therapies can play a key role in inflammatory bowel disease (IBD) related stricture/fistula/abscess deferring or avoiding invasive surgery. Methods: A total of 112 studies pertaining to IIBD therapy for strictures/fistula/abscess between 2002 and December 2022 were included by searching Pubmed, Medline and Embase with a focus on technical/clinical success, recurrence, re-intervention and complications. Results: IIBD therapy for strictures include endoscopic balloon dilation (EBD), endoscopic stricturotomy (ES) and self-expanding metal stent (SEMS) placement. EBD is the primary therapy for short strictures while ES and SEMS can be used for refractory strictures. ES has higher long-term efficacy than EBD. SEMS is inferior to EBD although it can be useful in long, refractory strictures. Fistula therapy includes endoscopic incision and drainage (perianal fistula)/endoscopic seton (simple, low fistula) and endoscopic ultrasound-guided drainage (pelvic abscess). Fistulotomy can be done for short, superficial, single tract, bowel-bowel fistula. Endoscopic injection of filling agents (fistula plug/glue/stem cell) is feasible although durability is unknown. Endoscopic closure therapies like over-the-scope clips (OTSC), suturing and SEMS should be avoided for de-novo/bowel to hollow organ fistulas. Conclusion: IIBD therapies have the potential to act as a bridge between medical and surgical therapy for properly selected IBD-related stricture/fistula/abscess although future controlled studies are warranted.

Abstract
Self-expandable metal stent (SEMS) are widely utilized as a bridge to surgical intervention and for palliative treatment of malignant bowel obstructions. The risk of complications associated with SEMS is low in well-selected patients. Stent erosion is a rare but serious adverse event that is associated with high morbidity and mortality. Here, we report the case of a 74-year-old patient with a colonic obstruction secondary to a pelvic mass that was treated with SEMS and radiotherapy, who developed a partial thickness stent erosion and recurrent hematochezia 6 years after placement. Endoscopic retrieval was not technically feasible. During attempted surgical resection, massive hemorrhage occurred from a colonic-arterial fistula to the left external iliac artery resulting in death. While SEMS remain an effective, minimally invasive approach for the management of bowel obstructions, prolonged in-situ lifetime may confer an increased risk of serious adverse events including erosion and fistula formation.

Abstract
Colonic diverticulitis is one of the most common gastrointestinal diseases. There are several complications in colonic diverticulitis, such as stenosis, perforation, and abscess. Stenosis is a rare complication and can cause bowel obstruction. We report a case of colonic diverticulitis complicated by stenosis causing bowel obstruction. A 66-year-old Japanese man was referred to our hospital for abdominal pain. Computed tomography (CT) scans showed the presence of diverticula, concentric wall thickening, and pericolic fat stranding in the descending colon. He was diagnosed with descending colon diverticulitis. His abdominal pain improved with fasting and intravenous antibiotics. However, after three months, diverticulitis complicated by stenosis occurred in the descending colon. The stenosis was severe and was treated with left hemicolectomy. Histologic examination revealed diverticula, chronic inflammation, and fibrosis in the stenosis, with no malignancy. Stenosis caused by colonic diverticulitis can cause bowel obstruction. Conservative treatment may lead to recurrence, and surgical treatment is preferable.

Abstract
Strictures are among the most frequent complications in patients with Crohn's disease (CD), usually requiring a combined medical, surgical, and/or endoscopic approach to treatment. Currently, endoscopic balloon dilation (EBD) is the endoscopic treatment of choice, but its effectiveness is not universal, especially in the long term, and it is not free of complications. The technological evolution of stents in recent years has allowed their use in benign diseases of any origin and location, including inflammatory bowel disease (IBD). The current scientific evidence regarding the use of stents in strictures in IBD is limited and it should not be considered the first option in endoscopic treatment. Self-expandable metal stents (SEMS), but no biodegradable stents (BS), can work in cases that are refractory to anterior endoscopic treatment with EBD, in cases in which EBD is not possible, and in cases with strictures of greater length.

Abstract
Fluoroscopic-guided stent placement has become an advantageous treatment option for diverse gastrointestinal disorders. In addition to palliative stent placement in patients with inoperable cancers, stenting has gradually expanded to other conditions, including as a bridge to surgery, as well as in patients' benign lesions and anastomotic strictures or leaks. This narrative review describes the indications, efficacy and safety of stent placement from the esophagus to the colon, including current recommendations, recent updates, and novel stents.

Abstract
Endoscopic stenting is a well-established option for the treatment of malignant obstruction, temporary management of benign strictures, and sealing transmural defects, as well as drainage of pancreatic fluid collections and biliary obstruction. In recent years, in addition to expansion in indications for endoscopic stenting, considerable strides have been made in stent technology, and several types of devices with advanced designs and materials are continuously being developed. In this review, we discuss the important developments in stent designs and novel indications for endoluminal and transluminal stenting. Our discussion specifically focuses on (i) biodegradable as well as (ii) irradiating and drug-eluting stents for esophageal, gastroduodenal, biliary, and colonic indications, (iii) endoscopic stenting in inflammatory bowel disease, and (iv) lumen-apposing metal stent.

Abstract
OBJECTIVE Fibrotic strictures in the gastrointestinal tract are frequent in Crohn's disease. Endoscopic dilation is a standard treatment. However, recurrence is common after dilation and there are complications such as bleeding or perforation. Endoscopic treatment using self-expandable metal stents has shown diverging results. The aim of this study was to evaluate the outcome of endoscopic treatment with a self-expandable stent in ileocecal Crohn's disease. DESIGN/METHOD Patients with Crohn's disease and a symptomatic ileocecal stricture were eligible for prospective, consecutive inclusion in a single-centre setting. Patients were randomised to treatment with either 18 mm balloon dilatation (GroupDIL) or stenting (GroupSTENT) using a 20 mm diameter, partially covered Hanarostent NCN. Patients were followed for a minimum of 24 months postendoscopy. Outcomes were technical success, adverse events and clinical success (defined as no need for repeated interventions). RESULTS Thirteen patients (GroupDIL n=6; GroupSTENT=7) were included with twelve patients (GroupDIL n=5; GroupSTENT=7) being eligible for complete follow-up. Technical success was achieved in all cases. Adverse events were border-line significantly more common in the GroupSTENT: 4/7 (57%) (pain: n=3; pain and rectal bleeding: n=1) compared with the GroupDIL: 0/5 (0%), p=0.08, which resulted in preterm termination of the study. The clinical success rate was GroupSTENT: 6/7 (86%) vs GroupDIL: 1/5 (20%), p=0.07. CONCLUSION Patients with strictures related to Crohn's disease may benefit from treatment with self-expandable metal stents rather than dilatation. However, there seems to be an increased risk for patient pain after stenting, which has to be considered and handled. TRAIL REGISTRATION NUMBER The study was registered at Clinical Trials (NCT04718493).

Abstract
BACKGROUND Diverticular disease is one of the more common abdominal disorders. In 2016, approximately 130 000 patients received inpatient treatment for diverticular disease in Germany. The disease has a number of subtypes, each of which has an appropriate treatment. In this article, we present the current surgical indications and optimal timing of surgery for diverticular disease. METHODS This review is based on publications that were retrieved by an extensive, selective search in Medline and the Cochrane Library (1998-2018) for studies and guidelines with information on the indications for surgery in diverticular disease. RESULTS Studies of evidence grades 2 to 4 were available. Patients receiving a diagnosis of freely perforated diverticulitis and peritonitis (Classification of Diverticular Disease [CDD] type 2c) should be operated on at once. Covered perforated diverticulitis with a macroabscess (>1 cm, CDD type 2b) may be an indication for elective surgery after successful conservative treatment. New evidence from a randomized, controlled trial suggests that elective surgery should also be considered for patients with chronic recurrent diverticulitis (CDD type 3b). The decisive factor in such cases is the impairment of the quality of life for the individual patient. Elective surgery is indicated in chronic recurrent diverticulitis with complications (fistulae, stenoses). Asymptomatic diverticulosis (CDD type 0) and uncomplicated diverticulitis (CDD type 1) are not surgical indications. Likewise, in diverticular hemorrhage (CDD type 4), surgery is only indicated in exceptional cases, when conservative treatment fails. CONCLUSION The surgical indication and the proper timing of surgery depend on the type of disease that is present. Future studies should more thoroughly investigate the effect of surgery on the quality of life in patients with the various types of diverticular disease.

Abstract
Self-expandable metal stent (SEMS) placement has been suggested as a therapeutic modality for treating benign colorectal strictures. Covered stents are generally used, given the concerns regarding the efficacy and safety of uncovered stents. Hence, few studies have evaluated the efficacy and safety of uncovered SEMSs (UCSEMSs) in patients with refractory benign colorectal anastomotic strictures. In this study, 12 patients with postoperative benign symptomatic anastomotic strictures refractory to pneumatic dilation (range, 2–9) and transient indwelling-covered SEMSs were treated using UCSEMS. All enrolled patients were men (mean age, 61 years). Stent placement was successful in all 12 patients, and early clinical success was achieved in 11 (92%) patients. Four patients (25%) showed successful clinical outcomes without further intervention, but eight patients (75%) were clinically unsuccessful, and showed stricture recurrence or functional obstructive symptoms. Three patients underwent surgery, and the remaining five patients required repeat stent procedures. Despite the high reobstruction rate, the median follow-up period after UCSEMS placement was 16.7 months, demonstrating that UCSEMS may be able to achieve medium-term symptom relief without any complications. Therefore, UCSEMS may be an alternative option in exceptional circumstances in carefully selected patients, where invasive surgical treatments, such as stoma diversion, are not an option, thereby improving patients’ quality of life.

Abstract
Despite recent advances aimed to treat transmural inflammation in Crohn's disease (CD) patients, the progression to a structuring behavior still represents an issue for clinicians. As inflammation becomes chronic and severe, the attempt to repair damaged tissue can result in an excessive production of extracellular matrix components and deposition of connective tissue, thus favoring the formation of strictures. No specific and accurate clinical predictors or diagnostic tools for intestinal fibrosis exist, and to date, no genetic or serological marker is in routine clinical use. Therefore, intestinal fibrosis is usually diagnosed when it becomes clinically evident and strictures have already occurred. Anti-fibrotic agents such as tranilast, peroxisome proliferator-activated receptor gamma agonists, rho kinase inhibitors, and especially mesenchymal stem cell therapy have provided interesting results, but most of the evidence has been derived from studies performed in vitro. Therefore, current therapy of fibrotic strictures relies mainly on endoscopic and surgical procedures. Although its long-term outcomes may be debated, endoscopic balloon dilation appears to be the safest and most effective approach to treat appropriately selected strictures. The use of endoscopic stricturotomy is currently limited by the expertise needed to perform it and by the few data available in the literature. Some good results have been achieved by the positioning of self-expandable metal stents (SEMS). However, there is no concordance regarding the type of stent to use and for how long it should be left in place. The development of new specific SEMS may lead to better outcomes and to an increased use of this alternative in CD-related strictures.

Abstract
In recent years, self-expandable metal stents (SEMSs) have been employed to treat benign gastrointestinal strictures secondary to several conditions: Acute diverticulitis, radiation colitis, inflammatory bowel disease (IBD), and postanastomotic leakages and stenosis. Other applications include endometriosis and fistulas of the lower gastrointestinal tract. Although it may be technically feasible to proceed to stenting in the aforementioned benign diseases of the lower gastrointestinal tract, the outcome has been reported to be poor. In fact, in some settings (such as complicated diverticulitis and postsurgical anastomotic strictures), stenting seems to have a limited evidence-based benefit as a bridge to surgery, while in other settings (such as endometriosis, IBD, radiation colitis, etc.), even society guidelines are not able to guide the endoscopist through decisional algorithms for SEMS placement. The aim of this narrative paper is to review the scientific evidence regarding the use of SEMSs in nonmalignant diseases of the lower gastrointestinal tract, both in adult and pediatric settings.

Abstract
There are a variety of causes of intestinal obstruction, with the most common cause being malignant diseases; however, volvulus, inflammatory bowel disease or diverticulitis, radiation injury, ischemia, and pseudo-obstruction can also cause colonic obstruction. These are benign conditions; however, delayed diagnosis of acute intestinal obstruction owing to these causes can cause critical complications, such as perforation. Therefore, high levels of clinical suspicion and appropriate treatment are crucial. There are variable treatment options for colonic obstruction, and endoscopic treatment is known to be a less invasive and an effective option for such. In this article, the authors review the causes of benign colonic obstruction and pseudo-obstruction and the role of endoscopy in treating them.

Abstract
Colorectal cancer is the most common cancer in Japan. Approximately 10%-20% of the patients with colorectal cancer present with large bowel obstruction, and those who present with malignant colonic obstruction (MCO) require urgent decompression because MCO can cause electrolytic fluid imbalance, colonic necrosis, bacterial translocation, and death. Placement of colonic stents (self-expandable metallic stents) for MCO is a major and standard endoscopic treatment that has been available since 2012 in Japan. This review presents the current conditions and future prospects of this procedure based on the literature. The current indication of colonic stent placement is malignant colorectal stenosis. One of the purposes of using stents is palliative treatment; further, its advantages over emergency surgery with colostomy include avoidance of colostomy, relief of obstruction, shorter hospitalization, and better quality of life. In addition, stent placement can also be used as a bridge to surgery since the duration of the hospitalization is shorter and postoperative complications, colostomy rates, and mortality rates are lower with elective than with emergency surgery. Although recent studies have reported low complication rates related to colonic stents, complications may still occur, highlighting the importance of good preparation, adequate staffing, backup systems, and informed consent. The current major problem related to colonic stents is the lack of evidence on patients' long-term prognoses for bridge to surgery purposes, awaiting the results of ongoing clinical research.

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
INTRODUCTION The self-expanding metal stent (SEMS) has been used in malignant colorectal obstruction as a bridge to surgery or for palliative treatment. We report a case of obstructive descending colon diverticulitis in-stent restenosis, which is difficult to distinguish from colon cancer. PRESENTATION OF CASE A 48-year-old man presented with abdominal pain. Computed tomography demonstrated a segment of thickened wall in the descending colon with near-complete obstruction. Colonoscopy revealed stenosis over the entire circumference of the descending colon. Biopsy revealed no malignant findings. SEMS was inserted to improve bowel obstruction. However, bowel obstruction did not improve, and stent-in-stent insertion was performed. Because colon cancer could not be completely excluded, left hemicolectomy with lymph node dissection was performed. The pathological examination revealed colon diverticulitis and no malignant finding. DISCUSSION Benign colorectal diseases can present with symptoms similar to those of obstructive colorectal cancer. As a result, it was benign colorectal stenosis, but it was thought that resection should be considered when the malignant lesion is suspected. The use of SEMS in benign colorectal disease has been reported a few. Reinsertion of the stent for restenosis, in bridge to surgery, was also considered useful from the viewpoint of avoiding emergent operation and reducing complications. CONCLUSION For colon stenosis suspected of malignant disease, it was thought that resection by inserting SEMS should be taken into consideration even for benign disease as a result.

Abstract
Benign colonic anastomotic stenosis sometimes occurs after surgical resection and usually requires surgical or endoscopic dilation. Limited data are available on the effectiveness and safety of the endoscopic radial incision and cutting (RIC) method at sites other than the esophagus. The aim of this retrospective study was to investigate the effectiveness and safety of RIC dilation for severe benign anastomotic colonic stenosis. Subjects were 3 men (median age 72 years, range 65 - 76 years) who developed severe benign anastomotic stenosis after surgical resection for colorectal carcinoma and were subsequently treated by RIC dilation at Hiroshima City Asa Citizens Hospital between May 2014 and December 2016. Severe anastomotic stenosis was defined as a narrowed anastomosis through which a standard colonoscope could not be passed. The median interval from surgery to RIC was 21 months (range 9 - 29 months). RIC was successful in all 3 patients and reduced the severity of dyschezia postoperatively; 2 patients experienced improvement after a single RIC session and the other after 6 RIC sessions. No treatment-related adverse events or re-stenosis requiring repeat dilation was noted during a median follow-up of 27 months (range 8 - 37 months). Our findings indicate that the RIC technique can be applied safely and effectively to various sites in the colon, avoiding the need for reoperation.

Abstract
BACKGROUND Complications in colorectal surgery include a wide range of clinical conditions, which increase mortality, morbidity, hospital stay and costs. In some cases, the placement of a self-expanding metal stent may represent a possible therapeutic strategy, avoiding further surgery. METHODS In order to verify the feasibility and safety of the technique, we reviewed the medical literature, between January 1997 and 2015, selecting 32 studies. Inclusion criteria were based on Preferred Reporting Items for Systematic reviews and Meta-Analyses recommendations. RESULTS The estimated rate of early success was 73.3% (95% CI 66.3-79.3), raising from 25 to 68% in the time frame 1997-2007. The rate of early complications was 31.4% (95% CI 25.3-38.3%), progressively decreasing from 75 to 43% up to 2009. The rate of surgery for acute complication was 9.3% (95% CI 6.0-14.2%), reduced on time course from 25 to 9%. The rate of closure of dehiscence was 74.5% (95% CI 62.8-83.5%), while the rate of long-lasting success was 57.3% (95% CI 50.3-64.0%). CONCLUSIONS Endoscopic stenting in the early postoperative management of anastomotic complications after colorectal surgery should be considered in patients with minimal risk for sepsis, as a safe and often effective alternative to surgery. However, in order to establish the safety and efficacy of this technique, prospective studies involving a larger cohort of patients are required.

Abstract
Ischemic colitis (IC) is a common reason of acute lower gastrointestinal bleeding, and it is frequently seen in elderly people. In recent years, both the incidence and prevalence of IC have been rising. Most episodes of IC are transient and self-limited and only a minority of cases are severe. IC often has missed and delayed diagnosis. This review mainly focuses on the progress in the understanding of the diagnosis and therapy of IC.

Abstract
Colonic postanastomotic strictures occur in 1.5–8% of patients following colorectal surgery. Traditionally, colonic strictures were treated by multiple modalities including endoscopic dilatation. Self-expanding metal stents (SEMS) have been indicated in the management of benign colonic strictures; however, there are limited available data with regard to their efficacy. We present the case of a 68-year-old male who had perforated sigmoid diverticulitis followed by Hartmann's procedure with eventual reanastomosis 6 months later. He subsequently developed benign colonic stricture, which was treated with a metal stent. SEMS are associated with a low mortality rate and are appropriate in treating acute colonic obstruction as a result of benign stricture in the setting of postanastomosis.

Abstract
BACKGROUND AND AIMS Stenosis is one of the most frequent local complications in Crohn's disease (CD). Surgery is not the ideal treatment because of the high rate of postoperative recurrence. Endoscopic balloon dilation (EBD) currently is the current treatment of choice for short strictures amenable to the procedure. However, it is not applicable or effective in all the cases, and it is not without related complications. Our goal was to summarize the published information regarding the use and the role of the stents in the treatment of CD stricture. A Medline search was performed on the terms "stricture," "stenosis," "stent" and "Crohn's disease." RESULTS a total of 19 publications met our search criteria for an overall number of 65 patients. Placing a self-expanding metal stent (SEMS) may be a safe and effective alternative to EBD and/or surgical intervention in the treatment of short stenosis in patients with CD. Indications are the same as those for EBD. In addition, SEMS may be useful in stenosis refractory to EBD and may be suitable in the treatment of longer or more complex strictures that cannot be treated by EBD. With the current information, it seems that the best treatment option is the placement of a fully covered stent for a mean time of 4 weeks. Regarding the use of biodegradable stents, the information is limited and showing poor results. CONCLUSIONS the use of stents in the treatment of strictures in CD should be taken into account either as a first endoscopic therapy or in case of EBD failure.

Abstract
Acute malignant colorectal obstruction is a complication of colorectal cancer that can occur in 7%-29% of patients. Self-expanding metallic stent placement for malignant colorectal obstruction has gained popularity as a safe and effective procedure for relieving obstruction. This technique can be used in the palliation of malignant colorectal obstruction, as a bridge to elective surgery for resectable colorectal cancers, palliation of extracolonic malignant obstruction, and for nonmalignant etiologies such as anastomotic strictures, Crohn’s disease, radiation therapy, and diverticular diseases. Self-expanding metallic stent has its own advantages and disadvantages over the surgery in these indications. During the insertion of the self-expanding metallic stent, and in the follow-up, short term and long term morbidities should be kept in mind. The most important complications of the stents are perforation, stent obstruction, stent migration, and bleeding. Additionally, given the high risk of perforation, if a patient is treated or being considered fortreatmentwith antiangiogenic agents such as bevacizumab, it is not recommended to use self-expanding metallic stent as a palliative treatment for obstruction. Therefore, there is a need for careful clinical evaluation for each patient who is a candidate for this procedure. The purpose of this review was to evaluate self-expanding metallic stent in the management of the obstruction of the colon due to the colorectal and extracolonic obstruction.

Abstract
Since the development of uncovered self-expanding metal stents (SEMS) in the 1990s, endoscopic stents have evolved dramatically. Application of new materials and new designs has expanded the indications for enteral SEMS. At present, enteral stents are considered the first-line modality for palliative care, and numerous types of enteral stents are under development for extended clinical usage, beyond a merely palliative purpose. Herein, we will discuss the current status and the future development of lower enteral stents.

Abstract
BACKGROUND/AIMS There has been a lack of research comparing balloon dilatation and self-expandable metal stent (SEMS) placement to determine which is better for long-term clinical outcomes in patients with benign colorectal strictures. We aimed to compare the clinical efficacy and complication rates of balloon dilatation and SEMS placement for benign colorectal strictures from a variety of causes. METHODS Between January 1999 and January 2012, a total of 43 consecutive patients who underwent endoscopic treatment for benign colorectal stricture (balloon only in 29 patients, SEMS only in seven patients, and both procedures in seven patients) were retrospectively reviewed. RESULTS Thirty-six patients underwent endoscopic balloon dilatation, representing 65 individual sessions, and 14 patients received a total of 17 SEMS placements. The initial clinical success rates were similar in both groups (balloon vs SEMS, 89.1% vs 87.5%). Although the reobstruction rates were similar in both groups (balloon vs SEMS, 54.4% vs. 57.1%), the duration of patency was significantly longer in the balloon dilatation group compared with the SEMS group (65.5±13.3 months vs. 2.0±0.6 months, p=0.031). CONCLUSIONS Endoscopic balloon dilatation is safe and effective as an initial treatment for benign colorectal stricture and as an alternative treatment for recurrent strictures.

Abstract
Advances in stents design have led to a substantial increase in the use of stents for a variety of digestive diseases. Initially developed as a non-surgical treatment for palliation of esophageal cancer, the stents now have an emerging role in the management of malignant and benign conditions as well as in all segments of the gastrointestinal tract. In this review, relevant literature search and expert opinions have been used to evaluate the key-role of stenting in gastrointestinal benign and malignant diseases.

Abstract
Colonic strictures, both benign and malignant, are commonly encountered in clinical practice. Benign strictures are most commonly treated by balloon dilation and less frequently with stents. Balloon dilation can help forestall or obviate surgery in some patients. Colonic strictures of malignant etiology generally need to be managed by stents and/or surgery. This article reviews endoscopic approaches to the management of colonic strictures.

Abstract
BACKGROUND Colonic stenting has failed to show an improvement in mortality rates in comparison with emergency surgery for acute large-bowel obstruction. However, it remains unclear which patients are more likely to benefit from this procedure. OBJECTIVE The aim of this study is to identify factors that may be predictive of successful outcome of colonic stenting in acute large-bowel obstruction. DESIGN All patients undergoing colonic stenting for acute large-bowel obstruction between 1999 and 2013 were studied. The demographics and characteristics of the obstructing lesion were analyzed. SETTINGS This investigation was conducted at a district general hospital. PATIENTS A total of 126 (76 men; median age, 76 y; range, 42-94 y) with acute large-bowel obstruction were included in the analysis. INTERVENTION The insertion of a self-expanding metal stent was attempted for each patient to relieve the obstruction. MAIN OUTCOME MEASURES The primary outcomes measured were technical success in the deployment of the stent, clinical decompression, and perforation rates. RESULTS Technical deployment of the stent was accomplished in 108 of 126 (86%) patients; however, only 89 (70%) achieved clinical decompression. Successful deployment and clinical decompression was associated with colorectal cancer (p = 0.03), shorter strictures (p = 0.01), and wider angulation distal to the obstruction (p = 0.049). Perforation was associated with longer strictures (p = 0.03). LIMITATIONS This study was limited by its retrospective nature. CONCLUSION Colonic stenting in acute large-bowel obstruction is more likely to be successful in shorter, malignant strictures with less angulation distal to the obstruction. Longer benign strictures are less likely to be successful and may be associated with an increased risk of perforation.

Abstract
BACKGROUND Some patients with benign colorectal obstruction do not respond to endoscopic balloon dilation. Fully covered self-expandable metal stents (FCSEMSs) have several potential advantages over non-covered stents, including a higher likelihood of retrieval owing to limited local tissue reaction. However, the efficacy and safety of FCSEMSs in benign colorectal strictures have not yet been established. METHODS Retrospective analysis of prospectively collected data concerning patients with post-surgical benign symptomatic anastomotic colorectal strictures, refractory to endoscopic dilation and in whom FCSEMSs had been placed at our center. Technical success was defined as successful stent placement and deployment at the stricture site. Early clinical success was defined as symptom relief persisting at least for 3 days. Follow-up was based on monthly clinical evaluation and quarterly endoscopic assessment. Endoscopic stent removal was planned on the basis of clinical or endoscopic assessment. Prolonged clinical success was defined as persistent symptom relief during follow-up. RESULTS Technical and early clinical success were obtained in 16 of 16 (100%) patients. The median follow-up was 21 months. Prolonged clinical success was achieved in 9/16 (56%) cases. There was no major complication, including perforation and bleeding. Stent migration occurred in 3 (19%) cases, in two of them associated with clinical failure. The median stent diameter was significantly higher in patients with successful than in those with unsuccessful clinical outcome (26 vs. 20 mm, P = 0.006). The clinical success rate was 1/6 (17%) in patients who received a 20-22 mm stent and 8/10 (80%) in those who received a 24-26 mm stent, respectively (P = 0.035). CONCLUSIONS FCSEMSs can represent effective and safe treatment for refractory anastomotic colorectal strictures. Large diameter stents are warranted for better results.

Abstract
Self-expanding metal stents (SEMS) have emerged as an alternative to surgery in the treatment of malignant colorectal obstructions. There is limited data about their use for benign colonic obstructions, especially in regards to safety and long-term patency. We present a case in which long-term SEMS placement proved to be a durable option for over 4 years in a patient with a benign colonic stricture.

Abstract
AIM UK cancer guidelines recommend patients with colonic obstruction due to suspected malignancy be considered for stenting with a self-expanding metal stent (SEMS). Considerable variation in practice exists due to a lack of expertise, technical difficulties and other, as yet ill-defined features. This retrospective multi-centre study aims to determine the outcome following colonic stenting for large bowel obstruction and identify factors associated with successful intervention. METHOD A regional programme of colonic stenting for large bowel obstruction, in five UK centres from 2005 to 2010 was evaluated for outcome including technical and clinical success, survival, complications and reoperation. RESULTS A SEMS was inserted in 334 patients, including 264 (79.0%) for palliation and 52 (15.6%) as a bridge to surgery. Technical success was achieved in 292 (87.4%) patients, with 46 (13.8%) experiencing a complication or technical failure. Reoperation was required in 39 (14.8%) patients stented for palliation of colorectal cancer of whom 16 (6.1%) subsequently required a colostomy. A one-stage primary anastomosis was achieved in 35 (67.3%) of the 52 patients undergoing stenting as a bridge to resection. Technical success did not vary by indication or site of obstruction (P = 0.60) but was higher for operators who had performed more than 10 procedures (OR 3.34, P = 0.001). ASA grade ≥3 predicted a worse clinical outcome (OR 0.43, P = 0.04). The through-the-scope (TTS) endoscopy technique was more successful than radiological placement alone (90.3% vs 74.8%, P < 0.001). CONCLUSION Experienced operators using a TTS technique achieved a better outcome for the emergency management of large bowel obstruction. Older, sicker patients and those with extracolonic and benign strictures fared less well.

Abstract
AIM Colorectal obstruction due to benign disease is likely to become more prevalent. Self-expanding stents have been shown to be effective in reducing morbidity and allowing one-stage resection or improved palliation in colorectal cancer. This review assessed the use of self-expanding stents in benign colorectal obstruction. METHOD A systematic review was performed using PubMed, Embase and the Cochrane Library. Keywords included: 'benign disease' 'colorectal obstruction', 'stent', 'endoprosthesis' and 'prosthesis' Original articles from all relevant listings were sourced. These were hand searched for further articles of relevance. The main outcome measures assessed were technical and clinical success, perforation, reobstruction and stoma avoidance in the bridge to surgery population. RESULTS The search strategy identified 130 articles; the 21 included studies yielded a pooled analysis of 122 patients. Diverticulitis was the predominant aetiology (66/122, 54%). Technical success was achieved in 115/122 (94%) and clinical success in 108/120 (87%) patients. Overall, the perforation rate was 12% (15/122) and the reobstruction rate was 14% (17/122). A stoma was avoided in 48% (23/48) of bridge to surgery patients. Perforation and stoma avoidance in the bridge to surgery group were worse with an aetiology of diverticulitis. CONCLUSION Complication rates in stenting for benign colorectal obstruction are higher than for malignant obstruction. On the basis of limited published evidence, stenting cannot be recommended for benign colorectal obstruction.

Abstract
BACKGROUND The need for newer gastrointestinal (GI) stents has been continuously raised. Newly developed stents are generally tested for physical properties in vitro and directly introduced to clinical practice because there is no reliable animal model of GI obstruction. The aim of this study was to establish an animal model both that can represent obstruction of the GI tract and be used to develop new stents. MATERIAL AND METHODS Surgical obstruction of the descending colon by wrapping with a nonabsorbable synthetic mesh and rubber bands was made in 17 healthy mongrel dogs. Four days later, a covered self-expanding metallic stent was placed for the obstructed segment in each dog under fluoroscopic guidance. Patency and migration of the inserted stents were evaluated clinically on a daily basis and fluoroscopically on a weekly basis. After sacrifice of the dogs, the degree and extent of residual colonic obstruction were assessed fluoroscopically. The specimen of the colonic obstructed segment was examined microscopically. RESULTS In all 17 mongrel dogs, segmental obstruction in the descending colon was successfully created and confirmed with fluoroscopic examination using a contrast medium. The percentage of luminal narrowing ranged from 99%-100%. Stent placement was technically successful in all 17 dogs. During the follow-up period, stent migration occurred in 12 dogs and indwelling time of a stent ranged from 0-95 d (mean 29.2 ± 38.8 d). On postmortem pathologic examination, it was found that fibrosis had newly formed outside the colonic longitudinal muscle layer in all dogs. CONCLUSIONS Our canine colonic obstruction model is the first animal model that can be feasible for developing a new design of stent and provide in vivo data on complications, particularly stent migration.

Abstract
Complications following gastrointestinal surgery may require re-intervention, can lead to prolonged hospitalization, and significantly increase health costs. Some complications, such as anastomotic leakage, fistula, and stricture require a multidisciplinary approach. Therapeutic endoscopy may play a pivotal role in these conditions, allowing minimally invasive treatment. Different endoscopic approaches, including fibrin glue injection, endoclips, self-expanding stents, and endoscopic vacuum-assisted devices have been introduced for both anastomotic leakage and fistula treatment. Similarly endoscopic treatments, such as endoscopic dilation, incisional therapy, and self-expanding stents have been used for anastomotic strictures. All these techniques can be safely performed by skilled endoscopists, and may achieve a high technical success rate in both the upper and lower gastrointestinal tract. Here we will review the endoscopic management of post-surgical complications; these techniques should be considered as first-line approach in selected patients, allowing to avoid re-operation, reduce hospital stay, and decrease costs.

Abstract
We present a rare case of toxic megacolon accompanied by necrosis of the colon due to chronic dilation caused by stenosis of the sigmoid colon as a complication of diverticulitis. The patient presented at the emergency department with diffuse abdominal pain, fever (38.8°C) and tachycardia (120 beats/min). Physical examination revealed distension and tenderness on deep palpation on the left lower quadrant without peritoneal signs. Abdominal computed tomography showed located stenosis in the sigmoid colon and marked dilation of the descending (12 cm diameter) and transverse (7.5 cm diameter) colon. A few hours later, the patient developed severe septic shock with electrolyte abnormalities. He had a history of two prior admissions to our hospital due to crises of acute diverticulitis. Based on Jalan's criteria the diagnosis was compatible with toxic megacolon. The patient's condition deteriorated suddenly and an emergency colectomy was performed. The operative findings revealed a necrotic colon. Histology examination confirmed the diagnosis of ischemia of the colon. To our knowledge this is the first published report in the literature which refers to a rare complication of diverticulitis, namely chronic stenosis which complicated to colonic ischemia and toxic megacolon.

Abstract
Recently, placement of self-expandable metallic stents has been used for the treatment of colorectal obstruction. As domestic awareness of colorectal cancer has increased, the number of colorectal stenting procedures performed has also increased. We aimed to provide evidence-based recommendations for colorectal stenting to aid gastroenterologists in making informed decisions regarding the management of patients who present with colorectal obstruction. The working group consisted of eight gastroenterologists who actively practice and conduct research in the field of colorectal stenting and are the members of the Stent Study Group of the Korean Society of Gastrointestinal Endoscopy. A literature search was conducted using the PubMed, Embase, KoreaMed, and the Cochrane Library databases to identify relevant articles published between January 2001 and June 2012. Based on the modified Delphi process, 10 recommendation statements regarding indications, usefulness, methodology and complications of colorectal stenting, and alternative treatments for malignant colorectal obstruction were determined. The contents will be widely distributed, and periodically revised to reflect the latest knowledge. These evidence-based recommendations for colorectal stenting will provide gastroenterologists and patients with appropriate and balanced information, and will improve the quality of care.

Abstract
BACKGROUND There has been no research on the clinical outcomes of secondary self-expandable metal stent (SEMS) placement after initial stent migration. Therefore, this study aimed to assess the clinical outcomes of secondary SEMS placement after initial stent migration compared to the outcomes of secondary SEMS placement done for reasons other than migration and identify factors predictive of long-term outcomes. METHODS Between January 2005 and February 2011, a total of 422 patients underwent SEMS insertion for malignant colorectal obstruction at Severance Hospital. Of these, there were 98 cases of secondary SEMS placement, 38 of which were due to previous stent migration. We compared the clinical outcomes of secondary SEMS between stent migration and nonmigration groups. We also sought to identify risk factors for long-term outcomes of secondary SEMS after initial stent migration. RESULTS The baseline clinical characteristics were similar between the two groups. The technical and clinical success rates of secondary SEMS insertion in the migration and nonmigration groups were 94.7% and 83.3% (p = 0.09) and 73.7% and 53.3% (p = 0.122), respectively. In the migration group, sustained clinical success after secondary SEMS was associated with the absence of complications after insertion of the first stent (p < 0.001) and a longer time interval (more than 100 days) between the first and second stent insertion (p = 0.011). CONCLUSIONS Our data showed that secondary colorectal SEMS after stent migration is safe and effective. Moreover, the sustained clinical success of the secondary stent following migration was dependent on the outcomes of the first stent.

Abstract
BACKGROUND Balloon dilation (with or without steroid injection) is the endoscopic treatment of choice for short strictures in Crohn's disease (CD). The placement of a stent has only rarely been reported in this setting, and it may be a good alternative. AIM To describe the efficacy of temporary placement of a self-expanding metallic stent (SEMS) in the endoscopic treatment of symptomatic strictures in CD. METHODS We included 17 CD patients treated with SEMS (4 partially covered SEMS and 21 fully covered SEMS) for symptomatic strictures refractory to medical and/or endoscopic treatment. RESULTS We placed 25 stents in 17 patients with stenosis (<8 cm), in the colon and in the ileocolonic anastomosis. In two cases, two stents were placed in the same endoscopic procedure. All except three cases had previously been unsuccessfully treated with endoscopic dilatation. The stents were maintained for an average of 28 days (1–112). The treatment was effective in 64.7% of the patients after a mean follow-up time of 60 weeks (5–266). In four cases, removal of the stents was technically difficult due to stent impaction (moderate adverse events-AEs) and one patient had a proximal stent migration requiring delayed surgery (severe AE). CONCLUSION The placement of self-expanding metallic stent in Crohn's disease maintained over a period of 4 weeks is a safe, effective treatment for strictures refractory to medical treatment and/or balloon dilatation, and might be an alternative endoscopic

Abstract
Ischemic colitis is the most common type of intestinal ischemia. The etiology of this condition is multifactorial, and the diagnosis is based on a combination of clinical symptoms, as well as endoscopic and histological findings. Although conservative therapy is effective in most cases, surgery still plays a key role in the treatment of ischemic colitis. Here, we describe a case of a 73-year-old man in whom laparoscopy-assisted left colectomy was performed 80 d after the onset of ischemic colitis. He recovered completely after surgery, and the pathological findings were consistent with ischemic colitis. To the best of our knowledge, there are no detailed reports of laparoscopic surgery for chronic segmental stenotic ischemic colitis. We discussed the usefulness of laparoscopic surgery, comparing it with endoscopic treatment, and we propose an optimal treatment strategy from a viewpoint of stenosis length and duration of disease.

Abstract
AIM Endoscopic decompression of malignant colorectal obstruction is often dealt with using expandable metallic stents. Endoscopic decompression of benign large bowel obstruction is more difficult. We report the technique and outcome of transanal endoscopic decompression for benign large bowel obstruction. METHOD From January 2001 to June 2010, endoscopic decompression using a transanal drainage tube placement was attempted in consecutive patients with benign large bowel obstruction. The clinical features, technical success, complications, treatment after the tube placement and clinical success were retrospectively evaluated. RESULTS There were 13 patients (seven males, age 47-87, mean 69 years). The sites of obstruction were transverse colon [5 (38%)], sigmoid colon [3 (23%)], ileocecal valve [2 (15%)], splenic flexure [1 (8%)], descending colon [1 (8%)] and rectum [1 (8%)]. The most common cause of obstruction was anastomotic stricture [9 (69%)]. In 12 (92%) patients transanal decompression was technically successful with one perforation. An overtube, the reinsertion of colonoscope along the decompression tube, or the use of a small-diameter endoscope was required for the tube placement in seven (54%). In seven (54%) patients tube placement alone resulted in relief of bowel obstruction without operation. CONCLUSION Endoscopic decompression using a transanal drainage tube is effective for the management of benign large bowel obstruction.
