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
Endoscopic luminal stenting (ELS) represents a minimally invasive option for the management of malignant obstruction along the gastrointestinal tract. Previous studies have shown that ELS can provide rapid relief of symptoms related to esophageal, gastric, small intestinal, colorectal, biliary, and pancreatic neoplastic strictures without compromising cancer patients’ overall safety. As a result, in both palliative and neoadjuvant settings, ELS has largely surpassed radiotherapy and surgery as a first-line treatment modality. Following the abovementioned success, the indications for ELS have gradually expanded. To date, ELS is widely used in clinical practice by well-trained endoscopists in managing a wide variety of diseases and complications, such as relieving non-neoplastic obstructions, sealing iatrogenic and non-iatrogenic perforations, closing fistulae and treating post-sphincterotomy bleeding. The abovementioned development would not have been achieved without corresponding advances and innovations in stent technology. However, the technological landscape changes rapidly, making clinicians’ adaptation to new technologies a real challenge. In our mini-review article, by systematically reviewing the relevant literature, we discuss current developments in ELS with regard to stent design, accessories, techniques, and applications, expanding the research basis that was set by previous studies and highlighting areas that need to be further investigated.

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
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
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.

Strictures in Crohn's Disease: From Pathophysiology to Treatment. Dig Dis Sci 2020; 65:1904-1916.

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.

Feasibility and safety of self-expandable metal stent in nonmalignant disease of the lower gastrointestinal tract. World J Gastrointest Endosc 2020; 12:60-71. [PMID: 32064031 PMCID: PMC6965004 DOI: 10.4253/wjge.v12.i2.60] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2019] [Revised: 12/08/2019] [Accepted: 12/13/2019] [Indexed: 02/06/2023] Open
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
Anastomotic leakage reflects a major problem in visceral surgery, leading to increased morbidity, mortality, and costs. This review is aimed at evaluating and summarizing risk factors for colorectal anastomotic leakage. A generalized discussion first introduces risk factors beginning with nonalterable factors. Focus is then brought to alterable impact factors on colorectal anastomoses, utilizing Cochrane systematic reviews assessed via systemic literature search of the Cochrane Central Register of Controlled Trials and Medline until May 2019. Seventeen meta-anaylses covering 20 factors were identified. Thereof, 7 factors were preoperative, 10 intraoperative, and 3 postoperative. Three factors significantly reduced the incidence of anastomotic leaks: high (versus low) surgeon's operative volume (RR = 0.68), stapled (versus handsewn) ileocolic anastomosis (RR = 0.41), and a diverting ostomy in anterior resection for rectal carcinoma (RR = 0.32). Discussion of all alterable factors is made in the setting of the pre-, intra-, and postoperative influencers, with the only significant preoperative risk modifier being a high colorectal volume surgeon and the only significant intraoperative factors being utilizing staples in ileocolic anastomoses and a diverting ostomy in rectal anastomoses. There were no measured postoperative alterable factors affecting anastomotic integrity.

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 Although self-expandable metal stents are used as a bridge to surgery in patients with colorectal cancer obstruction, their long-term oncological outcomes are unclear. OBJECTIVE The aim of this study was to investigate long-term oncological outcomes of self-expandable metal stents as a bridge to surgery (stent group) compared with direct surgery (direct operation group) in patients with left-sided colorectal cancer obstruction. DESIGN This was a retrospective chart review. SETTINGS This study was conducted at a single tertiary academic center. PATIENTS Of 113 patients who underwent curative surgery for left-sided colorectal cancer obstruction at Asan Medical Center between 2005 and 2011, 42 underwent direct surgery and 71 underwent self-expandable metal stent insertion followed by elective surgery. After 1:1 propensity-score matching, 42 patients were enrolled in both groups, and their postsurgical outcomes were compared. MAIN OUTCOME MEASURES The primary outcomes of this study were long-term oncological outcomes, including overall survival and recurrence-free survival of patients in both groups. RESULTS Three- and 5-year overall survival rates were similar in the stent (87.0% and 71.0%) and direct operation (76.4% and 76.4%) groups (p = 0.931). Three- and 5-year recurrence-free survival rates were also similar in the stent (91.9% and 66.4%) and direct operation (81.2% and 71.2%) groups (p = 0.581), as were postsurgical complication rates (9.5% and 16.7%; p = 0.344). No patient in either group experienced a permanent stoma. LIMITATIONS This study was limited by its small patient numbers and retrospective nature. CONCLUSIONS The long-term oncological outcomes of self-expandable metal stents as a bridge to surgery may not be inferior to those of direct surgery for left-sided colorectal cancer obstruction.

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
BACKGROUND Self-expandable metallic stents can be used to treat patients with symptomatic anastomotic complications after colorectal resection. METHODS Twenty patients with symptomatic anastomotic stricture after colorectal resection were treated with endoscopic placement of a self-expandable metal stent. Ten patients had "simple" anastomotic stricture. In the remaining 10 patients, a leak was associated with the stricture. RESULTS The anastomotic leakage healed without evidence of residual stricture or major fecal incontinence in 8 of 10 patients. Overall, the anastomotic stricture was resolved in 14 of the 20 patients. CONCLUSIONS Self-expandable metal stents represent a valid adjunctive to treat patients with symptomatic anastomotic complications after colorectal resection for cancer. They have a complementary role to balloon dilatation in case of simple anastomotic stricture, and they improve the rate of healing when the stricture is associated with a leak.

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.

Liang J, Church JM, Stocchi L, Fazio V, Kiran RP. Should bypass or stoma creation be undertaken for unresectable stage IV colorectal carcinoma? ANZ J Surg 2013; 84:275-9. [PMID: 23890342 DOI: 10.1111/ans.12267] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/14/2013] [Indexed: 11/30/2022]
Abstract
BACKGROUND When patients with stage IV colorectal cancer are deemed to have an unresectable primary colorectal cancer or extensive metastases at surgery, bypass or stoma creation may be the only surgical options. Whether this surgical approach provides extra months of life or instead leads to prohibitive post-operative morbidity and mortality has not previously been well characterized. This study was conducted to evaluate early and long-term outcomes for stage IV colorectal cancer patients with unresectable primary tumour. METHODS Patients with unresectable colorectal cancer who underwent palliative bypass or stoma creation were identified from a prospective colorectal cancer database. Early and long-term outcomes were evaluated. Survival was determined using Kaplan-Meier survival curves. RESULTS From 1980 to 2008, 81 patients with stage IV colorectal cancer had an unresectable primary or extensive metastases and underwent palliative bypass or stoma creation. Mean age was 61.5 ± 13.9 years, 44 (54.3%) were male. Location of the colorectal cancer was left-sided in 82.7%. Of the patients, 38.3% had emergency or urgent surgery. Sixty-two (76.5%) patients underwent a diverting stoma, 15 (18.5%) underwent enteric bypass procedures and 4 (4.9%) had both a diverting stoma and proximal bypass created. Twenty-five complications occurred in 24 patients (29.6%) with 2 patients (2.5%) requiring further re-operation. There was no anastomotic leak. Mean length of hospital stay was 13.8 ± 11.2 days. Thirty-day mortality rate was 16%. The median overall survival was 4.7 months, while the overall survival at 1 year was 24.7%. At 2 years, 6.1% patients were alive, all with a stoma. CONCLUSION Palliative bypass or stoma creation is associated with survival for several months for a significant proportion of patients with stage IV colorectal cancers, who have unresectable primaries or extensive metastases. The findings of this study support the use of bypass or diversion when faced with an unresectable primary in patients with colorectal cancer with metastases.

World J Gastrointest Surg 2012; 4:289-95.

Abstract
AIM: To verify the clinical results of the endoscopic stenting procedure for colorectal obstructions followed by laparoscopic colorectal resection with “one stage anastomosis”.
METHODS: From March 2003 to March 2009 in our surgical department, 48 patients underwent endoscopic stenting for colorectal occlusive lesion: 30 males (62.5%) and 18 females (37.5%) with an age range from 40 years to 92 years (median age 69.5). All patients enrolled in our study were diagnosed with an intestinal obstruction originating from the colorectal tract without bowel perforation signs. Obstruction was primitive colorectal cancer in 45 cases (93.7%) and benign anastomotic stricture in 3 cases (6.3%).
RESULTS: Surgical resection was totally laparoscopic in 69% of cases (24 patients) while 17% (6 patients) of cases were video-assisted due to the local extension of cancer with infiltrations of surrounding structures (urinary bladder in 2 cases, ileus and iliac vessels in the others). In 14% of cases (5 patients), resection was performed by open surgery due to the high American Society of Anesthesiologists score and the elderly age of patients (median age of 89 years). We performed a terminal stomy in only 7 patients out of 35, 6 colostomies and one ileostomy (in a total colectomy). In the other 28 cases (80%), we performed bowel anastomosis at the same time as resection, employing a temporary ileostomy only in 5 cases.
CONCLUSION: Colorectal stenting transforms an emergency operation in to an elective operation performable in a totally laparoscopic manner, limiting the confection of colostomy with its correlated complications.

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
BACKGROUND The role of endoluminal stenting in benign obstruction, especially for Crohn's disease (CD), is controversial, with limited data and widely disparate outcomes. The purpose of this study was to determine the long-term efficacy and safety of this technology in the treatment of fibrostenotic CD and to review the existing literature on this topic. METHODS We undertook a retrospective review of all patients undergoing endoluminal stenting for CD strictures at our institution from 2001 to 2010. Outcome measures included technical success, clinical improvement, duration of stent and luminal patency, and need for re-intervention. RESULTS Five patients underwent this procedure with a 100% rate of technical and an 80% rate of clinical success. Mean follow-up was 28 months (range 3 weeks to 109 months) and mean long-term luminal patency was 34.8 months (range 4.5-109 months). There was one complication involving reobstruction which required surgical intervention and no mortalities. CONCLUSIONS Endoluminal stenting of CD strictures is a safe and effective alternative to surgery which can provide lasting benefit in select patients. Further studies are necessary to clarify the full impact of this technology on long-term management of this complex disease.

Abstract
Background/Aims There are limited data regarding the clinical outcomes of self-expandable metal stents in the treatment of proximal colon obstruction. We compared the clinical outcomes of stent placement in patients with malignant proximal to distal colon obstructions. Methods We reviewed medical records from 37 consecutive patients from three institutions (19 men; mean age, 72 years) who underwent endoscopic stent placement at a malignant obstruction of the proximal colon. We also examined the records from 99 patients (50 men; mean age, 65 years) who underwent endoscopic stent placement for a distal colon obstruction. Technical success, clinical improvements, complications and stent patency were compared between treatments. Results The technical success rate tended to be lower in stents inserted to treat proximal colon obstructions than in those used to treat distal colon obstructions (86% vs 97%, p=0.06). Clinical improvement was achieved in 78% of patients (29/37) with proximal colonic stenting and in 91% of patients (90/99) with distal colonic stenting (p=0.08). Complications (24% vs 27%), stent migration (8% vs 8%) and stent reocclusion rates (11% vs 17%) did not differ significantly between groups. Two cases of bowel perforation related to stenting (5%) occurred in patients with proximal colonic stenting. Conclusions The technical success and clinical improvement associated with self-expandable metal stents used to treat proximal colon obstruction tend to be lower than cases of distal colon obstruction. Technical failure is an important cause of poor clinical improvement in patients with proximal colon stenting. Complication rates and stent patency appear to be similar in both groups.

Abstract
BACKGROUND The application of stents in benign colorectal strictures is considered controversial. The aim of the present study was to assess effectiveness and complications associated with colorectal stent placement in benign colorectal disease. PATIENTS AND METHODS Fourteen patients with benign colorectal strictures who had undergone previous surgery (colorectal anastomotic stenosis, 13; neosphincter scar stenosis, one) were treated with covered self-expanding metal stent or plastic stent. Placement of the stent was performed with combined endoscopy and contrast enhanced fluoroscopy. RESULTS Self-expanding stents were successful implanted in all 14 patients without acute procedure-related complications. All patients experienced immediate decompression after stent placement with expansion and patency of the stent. Relief of bowel obstruction for at least 12 months was achieved in seven of 14 patients (50%). Anastomotic fistula healed in four of six patients (67%). Despite the initial success of stenting, re-operations had to be performed in two of seven patients because of late recurrence of the stricture after a mean follow-up of 37 months. CONCLUSIONS Temporary insertion of self-expanding stents is a safe procedure that may be effective in selected cases of benign colorectal stricture. However, repeat surgery will be necessary in a considerable number of patients due to primary or secondary failure of stenting.

Abstract
Self-expanding metal stents (SEMS) are used to manage malignant colorectal obstruction. Colonic perforation is the most worrisome complication from colonic stenting. We reviewed causes and contributing factors of perforation with colonic stent placement in patients with malignant colorectal obstruction. Articles from both English and foreign language publications were identified from Medline. Data were collected on causes, timing, treatment and mortality related to perforation. A total of 2287 patients from 82 articles were included in this analysis, which showed an overall perforation rate of 4.9%. Perforation rates for palliation and bridge to surgery (BTS) were not significantly different (4.8% vs. 5.4%, p = 0.66); over 80% occurred within 30 days of stent placement (half during or within one day of the procedure). The mortality rate related to perforation was 0.8% per stented patient, but the mortality of patients experiencing perforation was 16.2%. There was no significant difference (p = 0.78) in the mortality rates between the palliation and the BTS group and concomitant chemotherapy, steroids, and radiotherapy are risk factors of perforation. The overall perforation related mortality is far less than that of patients undergoing emergency surgery for bowel obstruction.

Abstract
BACKGROUND Permanent metal stent placement for malignant intestinal obstruction has been proven to be efficient. Temporary stents for benign conditions of the colon and rectum are less studied. This is a case study, review of the literature, and observation from an animal model on placement of stents in the colorectum for benign disease. MATERIALS AND METHODS A 55-year-old man presented with recurrent obstructions from a benign stricture of the distal sigmoid colon. After failed balloon dilations, a polyester coated stent was placed. The purpose of the stent was to improve symptoms and avoid surgery. The stent was expelled after 5 days. We conducted a literature review of stents placed for benign colorectal strictures and an animal study to evaluate stent migration. RESULTS In the literature, there were 53 reports of uncovered metal stents, four covered metal stents, and six polyester stents. Patency rates were 71%, and migration rate was 43%. Migration occurred earlier with polyester stents (mean=8 days) versus covered (32 days) or uncovered metal stents (112 days). Severe complications were seen in 23% of patients. Four 45-kg pigs underwent rectosigmoid transection with a 21-mm anastomosis and endoscopic placement of a Polyflex stent. Two stents were secured with suture. Stents without fixation were expelled within 24 h of surgery. Stents with fixation were expelled between postoperative days 2 and 14. CONCLUSION Stents for the treatment of benign colorectal strictures are safe, with comparable patency rates between stent types. Metal stents can cause severe complications. In a pig model, covered polyester stents tend to migrate early even with fixation. Further investigation needs to focus on new stent designs and/or better fixation.

Abstract
BACKGROUND Emergency surgery for malignant colon obstruction entails relatively high morbidity and mortality rates and typically necessitates a 2-step resection. These problems might be potentially mitigated by placement of a self-expanding metal stent (SEMS) as a bridge to surgery. A nitinol colorectal SEMS may offer several advantages, but available evidence on the utility of this SEMS type remains highly limited. OBJECTIVE Our purpose was to evaluate the effectiveness and safety as a bridge to surgery of a nitinol SEMS designed for colorectal use. DESIGN Prospective and retrospective multicenter clinical study. SETTING Sixteen European study centers. PATIENTS Thirty-six patients with malignant colonic obstruction. INTERVENTIONS Nitinol colorectal SEMS placement. MAIN OUTCOME MEASURES Technical success in accurate SEMS placement with coverage of the entire stricture length, clinical success in alleviating colonic obstructive symptoms, and bridging to elective surgery. RESULTS Technical success was achieved in 97% of patients with a 95% CI of 85% to 100% and clinical success in 81% (95% CI, 64%-92%). Elective surgery was performed in 94% (95% CI, 81%-99%) of patients at a median of 11 days (95% CI, 7-15 days) after SEMS placement. SEMS-related perforation occurred in 3 patients. LIMITATIONS No control group was included in this nonrandomized cohort study. CONCLUSIONS In this first comparatively large clinical study of a nitinol colorectal SEMS as a bridge to surgery, a high proportion of patients successfully proceeded to elective surgery after prior decompression by SEMS placement.

Abstract
Patients with advanced incurable colorectal cancer (CRC) face a grim prognosis. The goal of palliative intervention is directed at alleviating disease-related symptoms and improving quality of life. The provision of optimal palliative care for these patients is a compound and demanding process. This dilemma becomes more challenging when patients with advanced metastatic colorectal disease present with an incurable and asymptomatic primary lesion. Treatment options are numerous and include a variety of surgical and nonsurgical interventions. Most data regarding the role of surgery in palliation of CRC are from retrospective, nonrandomized case series. Surgical resection may provide good palliation of symptoms and prevent future tumor-related complications. Metal stents are also able to provide good palliative relief of obstruction and should be used when appropriate. The best palliative care will often require a multidisciplinary approach that involves input from surgical and nonsurgical teams, where treatment plans will be made in accordance with the wishes of the patient and family with a goal of decreasing morbidity and a focus on quality of life.

Abstract
BACKGROUND Self-expandable metal stents are used throughout the GI tract to relieve malignant obstructions. OBJECTIVE Our purpose was to determine the outcome after colonic stent placement into the proximal colon. DESIGN Medical records of patients from 3 institutions who underwent attempts at placement of self-expandable metal stents for malignant obstructions of the proximal colon were retrospectively reviewed. Extracted data included patient characteristics, obstruction location, and goal of procedure (palliation vs bridge to surgery). SETTING Academic medial centers. PATIENTS Those with right-sided malignant colonic obstruction. INTERVENTIONS Placement of colonic stent. MAIN OUTCOME MEASUREMENTS Initial technical success, relief of obstruction, and early and long-term complications. RESULTS Twenty-one patients (15 men, 6 women; mean age 67 years) were included. Tumor type was colonic adenocarcinoma in 19 patients. Obstruction was complete in 8 patients and subtotal in 13 patients. Stenting was attempted as a bridge to surgery in 8 patients and as palliation in 13 patients. Initial technical success was achieved in 20 of 21 patients (95%). Complete relief of obstruction was achieved in 17 of 20 patients who had technical success (85%), unachieved in 2 patients (No. 14 and 17), and unknown in 1 patient (No. 6). There were no procedure-related complications (bleeding, perforation, etc). The only long-term complication was stent reocclusion from tumor ingrowth. LIMITATIONS Retrospective, single-arm analysis. CONCLUSIONS Self-expandable metal stents appear to be safe and effective in the treatment of malignant obstruction of the proximal colon. Technical and clinical success rates are comparable to those seen with distal colonic stenting.

Abstract
BACKGROUND Census data predict a 43% increase in individuals who are 80 years and older by 2010. There is a lack of information concerning surgical outcomes in this patient population regarding colon cancer. Herein we report a 10-year experience of surgical outcomes. METHODS Medical records of patients age 80 years and older undergoing surgery for colon cancer from 1996 to 2006 were reviewed (study group). Patient demographics and clinical outcomes were compared with a randomly sampled control group of patients younger than 80 years. RESULTS Forty-seven patients 80 years and older underwent surgery. Study group patients had an increased length of stay (P = .02), more cardiopulmonary complications (P = .01), and 32% presented emergently. Emergent patients had a significantly longer hospital stay and a higher incidence of complications. Study group patients also had decreased 1-, 3-, and 5-year survival rates (71%, 48%, and 31%, respectively). CONCLUSIONS Patients age 80 years and older have increased postoperative cardiopulmonary complications, lower long-term survival rates, and often present emergently. Clinicians should make all attempts to optimize the cardiopulmonary status preoperatively in this patient population and attempt to perform these surgeries in nonemergent situations.

Abstract
OBJECTIVE To assess the safety and efficacy of self-expanding metallic stents (SEMS) placement for the relief of malignant colorectal obstruction in comparison to surgical procedures through a systematic review of the literature. SUMMARY BACKGROUND DATA Conventional therapies for relieving colorectal obstructions caused by cancer have high rates of morbidity and mortality, particularly when performed under emergency conditions, and palliative procedures resulting in colostomy creation can be a burden for patients and caregivers. METHODS A systematic search strategy was used to retrieve relevant studies. Inclusion of papers was established through application of a predetermined protocol, independent assessment by 2 reviewers, and a final consensus decision. Eighty-eight articles, 15 of which were comparative, formed the evidence base for this review. RESULTS Little high-level evidence was available. However, the data suggested that SEMS placement was safe and effective in overcoming left-sided malignant colorectal obstructions, regardless of the indication for stent placement or the etiology of the obstruction. Additionally, SEMS placement had positive outcomes when compared with surgery, including overall shorter hospital stays, and a lower rate of serious adverse events. Postoperative mortality appeared comparable between the 2 interventions. Combining SEMS placement with elective surgery also appeared safer and more effective than emergency surgery, with higher rates of primary anastomosis, lower rates of colostomy, shorter hospital stays, and lower overall complication rates. CONCLUSIONS Stenting appears to be a safe and effective addition to the armamentarium of treatment options for colorectal obstructions. However, the small sample sizes of the included studies limited the validity of the findings of this review. The results of additional comparative studies currently being undertaken will add to the certainty of the conclusions that can be drawn.

OBJECTIVE To assess the safety and efficacy of self-expanding metallic stents (SEMS) placement for the relief of malignant colorectal obstruction in comparison to surgical procedures through a systematic review of the literature. SUMMARY BACKGROUND DATA Conventional therapies for relieving colorectal obstructions caused by cancer have high rates of morbidity and mortality, particularly when performed under emergency conditions, and palliative procedures resulting in colostomy creation can be a burden for patients and caregivers. METHODS A systematic search strategy was used to retrieve relevant studies. Inclusion of papers was established through application of a predetermined protocol, independent assessment by 2 reviewers, and a final consensus decision. Eighty-eight articles, 15 of which were comparative, formed the evidence base for this review. RESULTS Little high-level evidence was available. However, the data suggested that SEMS placement was safe and effective in overcoming left-sided malignant colorectal obstructions, regardless of the indication for stent placement or the etiology of the obstruction. Additionally, SEMS placement had positive outcomes when compared with surgery, including overall shorter hospital stays, and a lower rate of serious adverse events. Postoperative mortality appeared comparable between the 2 interventions. Combining SEMS placement with elective surgery also appeared safer and more effective than emergency surgery, with higher rates of primary anastomosis, lower rates of colostomy, shorter hospital stays, and lower overall complication rates. CONCLUSIONS Stenting appears to be a safe and effective addition to the armamentarium of treatment options for colorectal obstructions. However, the small sample sizes of the included studies limited the validity of the findings of this review. The results of additional comparative studies currently being undertaken will add to the certainty of the conclusions that can be drawn.

Abstract
Surgical resection of colorectal carcinoma is the only curative treatment currently available. In the elective setting peri-operative mortality is low and refinements in surgical technique and peri-operative care have resulted in high primary anastamosis rates and progressively reduced postoperative morbidity. In those presenting with large bowel obstruction the mortality and morbidity remains high. Many of those undergoing surgery will have incurable disease and a short life expectancy. Increasingly self-expanding metal stents are being deployed as either a 'bridge to surgery' or for palliation. This review covers the imaging appearances, detection and management of complications of colonic stenting.

Abstract
BACKGROUND Colorectal stents are being used for palliation and as a "bridge to surgery" in obstructing colorectal carcinoma. The purpose of this study was to review our experience with self-expanding metal stents (SEMS) as the initial interventional approach in the management of acute malignant large bowel obstruction. METHODS Between February 2002 and May 2006, 67 patients underwent the insertion of a SEMS for an obstructing malignant lesion of the left-sided colon or rectum. RESULTS In 55 patients, the stents were placed for palliation, whereas in 12 they were placed as a bridge to surgery. Stent placement was technically successful in 92.5% (n = 62), with a clinical success rate of 88% (n = 59). Two perforations that occurred during stent placement we retreated by an emergency Hartmann operation. In intention-to-treat by stent, the peri-interventional mortality was 6% (4/67). Stent migration was reported in 3 cases (5%), and stent obstruction occurred in 8 cases (13.5%). Of the nine patients with stents successfully placed as a bridge to surgery, all underwent elective single-stage operations with no death or anastomotic complication. CONCLUSIONS Stent insertion provided an effective outcome in patients with malignant colonic obstruction as a palliative and preoperative therapy.

Abstract
BACKGROUND General surgeons are frequently confronted with colorectal diseases in their daily practice, whereby colorectal cancer is the second most common malignant tumour, with almost 5000 new cases every year in Austria. The incidence of benign colon disorders requiring surgery (e.g. colon polyps, sigmoid diverticulitis) is also increasing. The first aim in colon surgery should be to avoid complications and if they occur to treat them properly. METHODS We basically distinguish between general and special complications. As general complications, prevention of malnutrition and support of the immune system should receive special attention. As the number of elderly patients increases, so does the risk not only of thrombembolic complications but also of critical cardiocirculatory situations, and renal and hepatic failure. Special complications depend either on the type of surgery (laparoscopic assisted, conventional open surgery) or the techniques employed (stapled, hand sutured). Handling of the tissue also plays a major role (e.g. dry versus wet pads). RESULTS Shortening of the postoperative stay decreases both hospital costs and the incidence of infections, meaning that minimally invasive surgery and postoperative "fast track nutrition" should be promoted. Emergency operations should be avoided (e.g. bridging through colonic stents), as morbidity and mortality are clearly increased in comparison to (semi-) elective operations. During the operation itself, new equipment and techniques (such as Ultracision®, Ligasure®) as well as a well coordinated team help to reduce complications and duration of surgery. CONCLUSIONS To avoid is better than to repair. If complications do occur, appropriate surgical and intensive - care measures should be taken immediately.

Abstract
Much of the workload of a typical gastroenterologist is devoted to screening patients for gastrointestinal malignancies. Efforts such as colorectal cancer screening via colonoscopy and endoscopic surveillance of patients with Barrett's esophagus are widespread and widely endorsed. In recent years, the armamentarium of endoscopy has broadened considerably and now affords physicians a variety of nonsurgical means to palliate malignant obstruction of the gastrointestinal tract. This article reviews endoscopic techniques to treat malignant esophageal, biliary, small bowel, and colonic obstruction.

Abstract
Creating blow-hole colostomy for decompression could provide a time-saving and efficient surgical procedure for a severely debilitated case with a completely obstructed colorectal cancer. Complications are reported as prolapse, retraction, and paracolostomal abscess. However, complication with an ischemic distal limb has not been reported. We report a case of critical intra-abdominal disease after decompressed colostomy for relieving malignant sigmoid colon obstruction; a potential fatal condition should be alerted. A 76-year-old male visited our emergency department for symptoms related to obstructed sigmoid colon tumor with foul-odor vomitus containing fecal-like materials. An emergent blow-hole colostomy proximal to an obstructed sigmoid lesion was created, and resolution of complete colon obstruction was pursued. Unfortunately, extensive abdominal painful distention with board-like abdomen and sudden onset of high fever with leukocytopenia developed subsequently. Such surgical abdomen rendered a secondary laparotomy with resection of the sigmoid tumor along with an ischemic colon segment located proximally up to the previously created colostomy. Eventually, the patient had an uneventful postoperative hospital stay. In the present article, we have described an emergent condition of sudden onset of distal limb ischemia after blow-hole colostomy and concluded that despite the decompressed colostomy would resolve acute malignant colon obstruction efficiently; impending ischemic bowel may progress with a possible irreversible peritonitis. Any patient, who undergoes a decompressed colostomy without resection of the obstructed lesion, should be monitored with leukocyte count and abdominal condition survey frequently.

Abstract
OBJECTIVE The use of stents for benign colorectal obstruction is considered controversial because of a lack of data and perceived high failure and complication rates. The aim of this study was to evaluate the indications and outcomes following stent placement for benign colorectal disease in a UK district general hospital and to review the published literature. PATIENTS AND METHODS Between 1997 and 2004, 11 of 90 attempted stent insertions were performed for benign colorectal disease (diverticular disease, 4; anastomotic strictures, 4; idiopathic rectal stricture, 1; rectal endometriosis, 1; caecal volvulus, 1). Complications and outcomes were analysed from a prospective database. RESULTS Stent insertion was successful in nine patients. Early complications occurred in two patients (both with diverticular disease): one patient failed to decompress and needed a colostomy and laparotomy was performed in a second patient who developed peritonitis after five days although no stent perforation of the bowel was identified. Two patients were successfully decompressed and underwent subsequent elective surgery with full bowel preparation. Stent placement resulted in symptomatic improvement in three out of four patients with anastomotic strictures (allowing closure of defunctioning stomas) and in the one patient with an idiopathic rectal stricture. Stent migration occurred in two of these patients without recurrence of symptoms. Stent fracture occurred in one patient, who remained symptomatic. CONCLUSIONS Self-expanding metallic stents are an effective treatment for benign colorectal obstructions, especially anastomotic strictures with long-term patency. Stents should be avoided in acute diverticular disease because of a higher incidence of complications.

Abstract
Malignant large bowel obstruction remains a clinical entity that is commonly encountered despite our advances in screening for colorectal cancer. Patients with malignant large bowel obstruction usually have advanced colorectal cancer and are often poor operative candidates, yet these patients are in need of treatment and colonic decompression. Surgical therapies are available and can offer good outcomes in selected patients. Patients who have curative or palliative surgeries planned should routinely undergo preoperative endoscopic decompression. Available options for decompression include the placement of colonic decompression tubes, ablative methods such as the use of lasers, argon plasma coagulators, and the use of self-expanding metal stents. The author favors the use of self-expanding metal stents, as these devices provide rapid colonic decompression, create a wide luminal diameter, and are applicable in patients requiring preoperative decompression and bowel preparation as well as in patients undergoing palliative therapy only. Patients who go on to surgery can have the stent and tumor removed en bloc at the time of the procedure, whereas patients who are only candidates for palliation can have the stents left in place as permanent decompressive devices with minimal morbidity and mortality.

Abstract
OBJECTIVE Acute large-bowel obstruction (LBO) is considered a surgical emergency. In gynecologic oncology patients with LBO due to recurrent tumor, surgery has been the standard treatment. However, operative intervention has significant associated morbidity and mortality. Recent reports have addressed the use of colorectal stents for the treatment of colonic malignancies. We are reporting our experience with colorectal stents in gynecologic oncology patients. METHODS We reviewed the records of all patients who underwent colorectal stent placement for palliation of LBO due to recurrent gynecologic malignancy from August 2001 to January 2003. RESULTS Six patients were identified; five patients had recurrent ovarian cancer and one had recurrent endometrial cancer. The mean age of the six patients at the time of stent placement was 51.5 years (range, 22-83 years). The length of LBO ranged from 2 to 10 cm. Two patients had a lumen of 1 to 2 mm before stent placement, while the other four had a complete obstruction and needed balloon dilatation before the deployment of the stent. Four (67%) of six patients had immediate relief, with passage of stool and flatus noted at the time of the colorectal stent placement. Stent placement failed to relieve the LBO in two patients (33%); these patients went on to receive colostomies. Of the four patients who had successful stent placement, the mean survival after stent placement was 120 days. One patient had a contained sigmoid bowel perforation noted 12 days after stent placement, which resolved with conservative measures. CONCLUSION Colonic stents appear to be a useful option in the management of patients with LBO due to recurrent gynecologic malignancy.

Abstract
AIM: To assess the effectiveness of and complications associated with metallic stent placement for treatment of anastomotic colonic strictures.
METHODS: A 46-year-old man underging two procedures of surgery for perforation of descending colon due to a traffic accident presented with pain, abdominal distention, and inability to defecate. Single-contrast barium enema radiograph showed a severe stenosis in the region of surgical anastomosis and the patient was too weak to accept another laparotomy. Under fluoroscopic and endoscopic guidance, we placed two metallic stents in the stenosis site of the anastomosis of the patient with anastomotic colonic strictures.
RESULTS: In this case of postsurgical stenosis, the first stent relieved the symptoms of obstruction, but stent migration happened on the next day so an additional stent was required to deal with the stricture and relieve the symptoms.
CONCLUSION: This case confirms that metallic stenting may represent an effective treatment for anastomotic colonic strictures in the absence of other therapeutic alternatives.

Abstract
BACKGROUND Acute colonic obstruction because of malignancy is often a surgical emergency. Surgical decompression with colostomy with or without resection and eventual re-anastomosis is the traditional treatment of choice. Endoscopic colonic stent insertion effectively decompresses the obstructed colon, allowing for surgery to be performed electively. This study sought to determine the cost-effectiveness of colonic stent vs. surgery for emergent management of acute malignant colonic obstruction. METHODS Decision analysis was used to calculate the cost-effectiveness of two competing strategies in a hypothetical patient presenting with acute, complete, malignant colonic obstruction: (1) emergent colonic stent followed by elective surgical resection and re-anastomosis; (2) emergent surgical resection followed by diversion (Hartmann's procedure) or primary anastomosis. Cost estimates were obtained from a third-party payer perspective. Primary outcome measures were mortality, stoma requirement, and total number of operative procedures. RESULTS Colonic stent resulted in 23% fewer operative procedures per patient (1.01 vs. 1.32 operations per patient), an 83% reduction in stoma requirement (7% vs. 43%), and lower procedure-related mortality (5% vs. 11%). Colonic stent was associated with a lower mean cost per patient ($45,709 vs. $49,941). CONCLUSIONS Colonic stent insertion followed by elective surgery appears more effective and less costly than emergency surgery under base-case conditions. This finding remains robust over a wide range of assumptions for clinical inputs in sensitivity analysis. Our findings suggest that colonic stent insertion should be offered, whenever feasible, as a bridge to elective surgery in patients presenting with malignant colonic obstruction.

Abstract
BACKGROUND Self-expanding metal stents have been used in the management of colorectal obstruction as an alternative to emergency surgery. Our aim was to systematically review the efficacy and safety of these stents in the setting of malignant colorectal obstruction. METHODS Both English and foreign language reports were identified from Medline, Embase, Cancerlit, Science Citation Index, Cochrane Library, and proceedings of relevant meetings. Data were collected on technical success, clinical success, and safety parameters. RESULTS Fifty-four studies reported the use of stents in a total of 1,198 patients. The median technical and clinical success rates were 94% (i.q.r. 90-100) and 91% (i.q.r. 84-94), respectively. The clinical success when used as a bridge to surgery was 71.7%. Major complications related to stent placement included perforation (3.76%), stent migration (11.81%), and reobstruction (7.34%). Factors related to an increased complication risk were identified. Stent-related mortality was 0.58%. Limited available data suggest that this approach may be cost effective in the preoperative setting. CONCLUSION Placement of self-expanding metal stents is an effective and safe definitive procedure in the palliation of malignant colorectal obstruction. In operable patients, it provides a useful option to avoid colostomy, by facilitating safer single-stage surgery.

Abstract
A case of an 82-year-old woman is reported who developed a lower gastrointestinal hemorrhage secondary to metastatic ovarian carcinoma to the colon. The bleeding, associated with an incomplete obstruction of the large bowel, was successfully treated with the endoscopic insertion of two self-expanding metal stents. A technique of stent placement is presented which differs from that previously reported, where both stents were via colonoscopy and without the use of fluoroscopy.

Abstract
The primary mode of therapy for colon cancer continues to be surgery. Although little has changed in the technical aspects of colonic resection, a great deal of research has taken place to develop procedures that enhance staging of disease, optimize postoperative recovery, and improve outcomes in obstructed patients without compromising cancer-related morbidity and mortality. This review explores the current use of laparoscopy, sentinel node biopsy, intraoperative ultrasound, and colonic stents in the elective and emergent management of colon cancer.

Abstract
BACKGROUND Colorectal stents are being used for palliation and as a 'bridge to surgery' in obstructing colorectal cancers. METHODS A systematic review of the published data on stenting for the treatment of colorectal obstruction was carried out by searching Medline and other online databases for the period from January 1990 to December 2000. A total of 58 publications (case series, single case reports and reviews) was found, of which 29 case series were included in the analysis. Technical and clinical success, complications and reobstruction, both in palliation and as a 'bridge to surgery', were assessed. Both descriptive statistics and pooled analyses were carried out. RESULTS Pooled results showed that stent insertion was attempted in 598 instances. Technical success was achieved in 551 (92 per cent) and clinical success in 525 (88 per cent). Palliation was achieved in 302 (90 per cent) of 336 cases, while 223 (85 per cent) of 262 insertions succeeded as a 'bridge to surgery' (95 per cent had a one-stage surgical procedure). There were three deaths (1 per cent). Perforation occurred 22 times (4 per cent). Stent migration was reported in 54 (10 per cent) of 551 technically successful cases. The rate of stent reobstruction was 52 (10 per cent) of 525, mainly in the palliative group. CONCLUSION Evidence suggests that colorectal stents offer good palliation, and are safe and effective as a 'bridge to surgery'. Stent usage can avoid the need for a stoma, and is associated with low rates of mortality and morbidity. Dilatation of malignant strictures at the time of stent placement appears to be dangerous and should be avoided.

Abstract
BACKGROUND The purpose of this study was to review our experience with self-expanding metal stents as the initial interventional approach in the management of acute malignant large-bowel obstruction. METHODS Twenty-six patients who underwent placement of colonic stents at our institution between June 1994 and June 2000 were identified and reviewed. RESULTS In 14 patients, the stents were placed for palliation, whereas in 12, they were placed as a bridge to surgery. In 22 patients (85%), stent placement was successful on the first occasion. In the remaining four individuals, one was successfully stented at the second occasion, and three required emergency surgery. Nine of the 12 patients (75%) in the bridge-to-surgery group underwent elective colon resection. In the palliative group, four patients (29%) had reobstruction of the stents, and in one (9%), the stent migrated. In the remaining nine patients (64%), the stent was patent until the patient died or until the time of last follow-up (median, 156 days). CONCLUSIONS In our experience with 26 patients who developed a complete bowel obstruction as a consequence of a malignant tumor, placement of colonic stents to achieve immediate nonoperative decompression proved to be both safe and effective. Subsequent elective resection was accomplished in the majority of resectable cases.

Abstract
BACKGROUND The purpose of this paper is to review and report our experience with colorectal stenting in the management of malignant large bowel obstruction. METHODS Twelve consecutive patients with malignant left-sided large bowel obstruction between June 1998 and January 2001 underwent insertion of self-expanding metallic stents. One patient required two stents. Eight stents were inserted under fluoroscopic guidance, and five were inserted with combined fluoroscopic and endoscopic guidance. Patients were followed up until death, stent removal or the time of publication. RESULTS Thirteen stents were inserted. Eleven patients with acute large bowel obstruction had relief of obstruction with stenting, and one of these patients required a second stent because relief had been incomplete. One patient was stented in order to subsequently close a problematic stoma. Technical success was 92.9% and clinical success was 100%. Three patients proceeded to surgical resection. In nine patients, the stent was left as the definitive procedure. Of these, six patients have died within 4 months. Complications included one case of migration, one case of reobstruction, one intestinal haematoma and one case of cheesewiring. CONCLUSIONS Colorectal stenting is an important treatment modality for malignant large bowel obstruction. It may be definitive treatment alone, or a bridge to elective surgical resection.

Abstract
Large bowel obstruction in the terminally ill patient can be difficult to manage. We describe a patient with sigmoid colon obstruction caused by metastatic prostate cancer in the pelvis who required hospitalization because of severe pain and obstructive symptoms. Treatment with an endoscopically placed self-expandable metal stent allowed the patient to have immediate resolution of symptoms and to receive hospice care at home.
