Background and Aim. Malignant hilar strictures are a clinical challenge because of the current therapeutic approach and the poor prognosis. In recent years, self-expandable metallic stents have proven more effective than plastic stents for palliation of malignant hilar strictures, with the bilateral stent-in-stent technique registering a high success rate. We report our experience with Y-shaped endoscopic self-expandable metallic stents placement for treatment of advanced malignant hilar strictures.Methods. From April 2009 to August 2012, we prospectively collected data on patients treated with Y-shaped SEMS placement for advanced malignant hilar carcinoma. Data on technical success, clinical success, and complications were collected.Results. Twenty patients (9 males) were treated (mean age 64.2 ± 15.3 years). The grade of malignant hilar strictures according to the Bismuth classification was II in 5 patients (25%), IIIa in 1 (5%), and IV in 14 (70%). The mean bilirubin level was 14.7 ± 4.9 mg/dL. Technical success was achieved in all patients, with a significant reduction in bilirubin levels (2.9 ± 1.7 mg/dL). One patient experienced cholangitis as early complication, while in 2 patients stent ingrowth was observed. No stents migration was recorded. There was no procedure-related mortality. At the end of the follow-up (7.1 ± 3.1 months), 13 of the 20 patients (65%) had died.Conclusions. Our experience confirms endoscopic bilateral self-expandable metallic stents placement with stent-in-stent technique (Y-shaped configuration) as a feasible, effective, and safe procedure for palliation of unresectable malignant hilar strictures.

Aims. Endoscopic self-expandable metallic stent (SEMS) insertion for acute colonic obstruction caused by colorectal cancer (CRC) is always performed under fluoroscopic guidance. This study evaluated the feasibility and safety of an endoscopic stenting procedure without fluoroscopic guidance. Methods. A total of 36 patients with an acute colonic obstruction caused by CRC underwent endoscopic SEMS insertion using a colonoscope without fluoroscopic guidance, followed by analyses of the technical and clinical success and short-term complications. Results. Total technical success rate and clinical success rate were 91.7% and 86.1%, respectively. The mean procedure time was 21.2±10.3 minutes. There was no stent dislodgement. One case of hematochezia and two cases of tenesmus occurred in patients with left-sided complete obstructions. No other short-term complications occurred. Procedure time, technical success, and clinical success rate were 16.3±9.4 minutes, 93.1%, and 89.6% for left-sided obstructions, respectively, and were 26.8±10.7 minutes, 85.7%, and 71.4% for right-sided obstructions, respectively. For complete obstructions, procedure time, technical success, and clinical success rate were 22.5±8.9 minutes, 90%, and 83.3%, respectively. In the incomplete cases, procedure time, technical success, and clinical success were 13.5±6.7 minutes, 100%, and 100%, respectively. Technical success, clinical success, and short-term complications were not differed between lesion locations and degrees. Conclusions. This simple technique is feasible and safe for palliation of acute colonic obstruction caused by CRC.

Benign Biliary Strictures

Background and aims: The goals of the management of benign biliary stricture (BBS) are to relieve symptoms and resolve short-/long-term stricture. We performed fully covered self-expandable metallic stent (hereafter, FCSEMS) placement for BBS using various methods and investigated the treatment outcomes and adverse events (AEs). Methods: We retrospectively studied patients who underwent FCSEMS placement for refractory BBS through various approaches between January 2017 and February 2020. FCSEMS were placed for 6 months, and an additional FCSEMS was placed if the stricture had not improved. Technical success rate, stricture resolution rate, and AE were measured. Results: A total of 26 patients with BBSs that were difficult to manage with plastic stents were included. The mean overall follow-up period was 43.3 ± 30.7 months. The cause of stricture was postoperative (46%), inflammatory (31%), and chronic pancreatitis (23%). There were four insertion methods: endoscopic with duodenoscopy, with enteroscopy, EUS-guided transmural, and percutaneous transhepatic. The technical success rate was 100%, without any AE. Stricture resolution was obtained in 19 (83%) of 23 cases, except for three cases of death due to other causes. Stent migration and cholangitis occurred in 23% and 6.3%, respectively. Stent fracture occurred in two cases in which FCSEMSs were placed for more than 6 months (7.2 and 10.3 months). Conclusion: FCSEMS placement for refractory BBS via various insertion routes was feasible and effective. FCSEMSs should be exchanged every 6 months until stricture resolution because of stent durability. Further prospective study for confirmation is required, particularly regarding EUS-guided FCSEMS placement.

Abstract Aims This updated systematic review aimed to assess the safety and effectiveness of oesophageal stents in these two scenarios. Background Endoscopic placement of oesophageal stents may be used in benign oesophageal perforation and oesophageal anastomotic leakage to control sepsis and reduce mortality and morbidity by avoiding thoracotomy. Methods A systematic literature search of all published studies reporting use of metallic and plastic stents in the management of postoperative anastomotic leaks, spontaneous and iatrogenic oesophageal perforations were identified. Primary outcomes were technical (deploying ≥1 stent to occlude site of leakage with no evidence of leakage of contrast within 24-48 hours) and clinical success (complete healing of perforation or leakage by placement of single or multiple stents irrespective of whether the stent was left in situ or was removed). Secondary outcomes were stent migration, perforation and erosion and mortality rates. Subgroup analysis were performed for plastic versus metallic stents and anastomotic leaks versus perforations separately. Results A total of 66 studies (n=1752 patients) were included. Technical and clinical success rates were 96% and 87%, respectively. Plastic stents had significantly higher migration rates (24% vs 16%, p=0.001) and repositioning (11% vs 3%, p<0.001) and lower technical success (91% vs 95%, p=0.032) than metallic stents. In patients with anastomotic leaks, plastic stents were associated with higher stent migration (26% vs 15%, p=0.034), perforation (2% vs 0%, p=0.013), repositioning (10% vs 0%, p<0.001) and lower technical success (95% vs 100%, p=0.002). In patients with perforations only, plastic stents were associated with significantly lower technical success (85% vs 99%, p<0.001). Conclusions Covered metallic oesophageal stents appear to be more effective than plastic stents in the management of oesophageal perforation and anastomotic leakage. However, quality of evidence of generally poor and high-quality randomised trial is needed to further evaluate best management option for oesophageal perforation and anastomotic leakage.

Tamponade Effect

The role of self-expandable metallic stents is gradually evolving for a diverse group of benign and malignant gastrointestinal tract problems, with luminal obstruction being by far the most common. Although its role in refractory variceal bleeding is well established, it has rarely been tried for tumor-related bleeding, with only a few case reports in this regard. We share our experience of successfully controlling esophageal tumor–related bleeding with the use of a fully covered self-expandable metallic stent. A 58-year-old woman with irresectable distal esophageal cancer, presented with hematemesis. Esophago-gastro-duodenoscopy revealed an obstructing esophageal tumor with diffuse oozing of blood. This was unamenable to local injection of adrenaline and hemospray; therefore, a temporary self-expandable metallic stent was parked to create a tamponade effect. This successfully stopped bleeding and the patient remained asymptomatic till discharge. However, she was lost to follow-up, and therefore, the stent was removed after a period of 5 months instead of 2 weeks.

Background and aims: Post liver transplant biliary anastomotic strictures have traditionally been treated with balloon dilation and multiple plastic stents. Fully covered self-expandable metallic stents may be used as an initial alternative or after multiple plastic stents failure. Refractory strictures can occur in 10–22% and require revisional surgery. Alternatively, cholangioscopy allows direct visualization and therapeutic approaches. We aimed to assess the feasibility, safety, and efficacy of balloon dilation combined with cholangioscopy-guided steroid injection for the treatment of refractory anastomotic biliary strictures. Methods: Three post-orthotopic liver transplant patients who failed standard treatment of their biliary anastomotic strictures underwent endoscopic retrograde cholangiopancreatography with balloon dilation followed by cholangioscopy-guided steroid injection at a tertiary care center. Patients had follow-up with images and laboratorial tests to evaluate for residual stricture. Results: Technical success of balloon dilation + cholangioscopy-guided steroid injection was achieved in all patients. Cholangioscopy permitted accurate evaluation of bile ducts and precise localization for steroid injection. No adverse events occurred. Mean follow-up was 26 months. Two patients are stent free and remain well in follow-up, with no signs of biliary obstruction. No further therapeutic endoscopic procedures or revisional surgery were required. One patient did not respond to balloon dilation + cholangioscopy-guided steroid injection after 11 months of follow-up and required repeat balloon dilation of new strictures above the anastomosis. Conclusion: Cholangioscopy-guided steroid injection combined with balloon dilation in the treatment of refractory post liver transplant strictures is feasible and safe. This method may be used as a rescue alternative before surgical approach. Randomized controlled trials comparing balloon dilation + cholangioscopy-guided steroid injection to fully covered self-expandable metallic stents are needed to determine the role of this treatment for anastomotic biliary strictures.

ABSTRACT Background and Aims: Endoscopic insertion of self-expandable metallic stent (SEMS) is now accepted as first line modality of treatment for palliation in unresectable extra-hepatic biliary obstructive jaundice. This study was done to assess the clinical efficacy and duration of patency of endoscopically inserted metallic stent in un-resectable malignant biliary obstruction. Materials and Methods: Between 2015 to 2017, 101 patients who underwent ERCP and SEMS placement for palliation of malignant biliary obstruction were included prospectively. Main outcome measures were technical success, clinical success, mean duration of SEMS patency, clinical efficacy, rate of biliary re-intervention and survival of patients. Results: Overall technical success and clinical success was achieved in 93% and 82.2% respectively. Mean duration of SEMS patency was 109 days. Analysis in subgroup of patients classified according to site of obstruction (Hilar -68, Distal CBD-33) showed that median duration of stent patency was significantly better in distal biliary stricture (135 days vs 95 days), whereas re-intervention rates were higher in higher biliary stricture than distal stricture (41% Vs 6%). Seven patients with hilar biliary stricture suffered post-SEMS insertion cholangitis. Conclusion: SEMS placement is feasible palliative method for un-resectable malignant biliary obstruction with acceptable technical and clinical success. The duration of SEMS patency and clinical efficacy is significantly better in distal biliary stricture whereas re-intervention rate is higher in hilar biliary stricture.

Abstract Background and aim To assess the rate of adverse events and the technical success rate of biliary stenting with or without EBS.  Methods A literature search up to February 2017 was performed. Studies assessing adverse events (AEs) and technical success rates of stenting with or without EBS were considered. Results Seven studies (870 patients; 12 treatment arms) were included. Early AEs, i. e. those occurring within 30 days, were significantly lower in no-EBS vs. EBS-group (11 % vs. 20.1 %; OR: 0.36, 95 %CI: 0.13 – 1.00). Rates of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis were not significantly different in the two groups (no-EBS vs. EBS: 6.1 % vs 5 %; OR: 1.33, 95 %CI: 0.68 – 2.59). The rate of bleeding was significantly lower in patients without EBS (no-EBS vs EBS: 0 % vs 5 %; OR: 0.12, 95 % CI: 0.03 – 0.45). Rates of cholangitis were significantly lower in patients without EBS (no-EBS vs. EBS: 3.3 % vs. 7.4 %; OR: 0.38, 95 %CI: 0.17 – 0.83). Both late AEs and mortality rates did not significantly differ between no-EBS and EBS patients (19.9 % vs. 18.9 %; OR: 0.93, 95 %CI: 0.56 – 1.53, and 2.5 % vs. 2.9 %; OR: 1.18, 95 %CI: 0.22 – 6.29, respectively). The technical success rate for stent insertion also did not differ (98 % vs. 97.6 %; OR: 1.05, 95 %CI: 0.42 – 2.63). Conclusion EBS seems to be associated, in the first 30 days after the procedure, with an increased risk of cholangitis and bleeding. No difference was observed in the rate of post-ERCP pancreatitis.
