134 Background: Self-expandable covered metal stents are an important component of palliative care for malignant dysphagia; however significant complication rates have been associated with large diameter stents. We hypothesized that small-caliber, fully covered, self-expandable metal stents (sccSEMS) would prove adequate palliation of dysphagia in the absence of major complications. Methods: Prospective observational study of 17 patients presenting with severe malignant dysphagia between 12/1/08 and 7/30/10. 31 sccSEMS with internal diameters ranging from 8 mm to 16 mm were placed in 17 patients with pre-stent luminal diameters of < 8 mm (n = 13) or 8-10 mm (n = 4). 7 tracheobronchial stents (internal diameter 14–16 mm), 2 biliary stents (internal diameter 8–10 mm), and 22 specially constructed esophageal stents (internal diameter 12–16 mm) were placed. All stents were placed under direct endoscopic vision without fluoroscopic support. Dysphagia scores, migration rates, and complications were identified through review of endoscopy reports, outpatient clinical encounters, and 24-hour post-procedure phone surveys. Anticipated stent migration was defined as events which occurred during chemoradiation. Unanticipated stent migration was defined as events which occurred in the absence of treatment. Results: The post-stent median dysphagia score improved (decreased) from 3 to 2 (p = 0.0003). The overall median duration of first stent placement was 64 days, IQR 32 – 110 days. The overall migration rate was 35.5% (11/31). The anticipated migration rate was 60% (9/15); the unanticipated migration rate was 18.2% (2/11) (p = 0.051). All 11 of the migrated stents were retrieved endoscopically without complication. 9.7% (3/31) of patients reported self-limited sore throat or chest pain within 24-hours of stent placement. All 3 patients were managed conservatively without need for narcotic analgesics, hospitalization, or repeat endoscopy. No other complications occurred. Conclusions: The direct endoscopic placement of sccSEMS in patients presenting with severe malignant dysphagia significantly improved dysphagia scores, provided excellent durability, and resulted in no major complications. No significant financial relationships to disclose.

151 Background: Use of large caliber ( ≥ 18 mm body diameter) self expanding metal stents (SEMS) for management of malignant dysphasia is associated with substantial adverse event (AE) and mortality rates (MRs). We sought to determine dysphagia response, stent migration rates, and AE and MRs, for small caliber covered SEMS (sccSEMS) with body diameters (BDs) between 10 - 16 mm in malignant dysphagia. Methods: We identified 31 patients underwent direct endoscopic placement of 50 sccSEMS. Patients were monitored for change in dysphagia score (DS), stent migration, AEs, and death. Results: The cohort consisted of 23 (74%) men and 8 (26%) women with a median age of 64 years (35 - 87 years). Esophageal adenocarcinoma (AC) was present in 19 (61%) patients and squamous cell carcinoma (SCCA) in 12 (39%) patients. Of the patients with SCCA, 2 tumors were located in the proximal esophagus, 7 in the mid-esophagus and 3 in the distal esophagus. All 19 ACs were located in the distal esophagus. The AJCC clinical stages at time of sccSEMS placement were: 1 (3%) Stage II, 8 (26%) Stage III, and 22 (71%) Stage IV. The initial pre-stent lumen diameter was less than 8 mm in 77% (24/31) of patients. The initial pre-stent lumen diameter was equal to 9 mm in 1 patient (3%), equal to 10 mm in 4 patients (13%), and equal to 11 mm in 2 patients (6%). The median pre-stent tumor length was 5.0 cm (interquartile range 4.0 – 7.0 cm). Dysphagia score improved in 30 of 31 patients (97%). The median DS decreased from 3 to 2 (p < 0.0001). The median effective duration of first sccSEMS placement was 116 (95% CI: 75-196) days. Major and minor AE rates were 6.5% and 19.4% respectively. No stent related deaths were encountered. The overall migration rate was 36% (18/50). The anticipated migration rate was 45.7% (16/35) and the unanticipated migration rate was 13.3% (2/15) (p = 0.052). Positive effective clinical outcome occurred in 93.5% (29/31) of cases. Conclusions: In malignant dysphagia, direct endoscopic sccSEMS placement provided acceptable dysphagia control and migration rates with substantial reductions in stent related AEs and MRs compared to those reported for large caliber SEMS.

Abstract Background and study aims Stent migration is a common complication of fully-covered self-expanding metal stents (FCSEMS), but the rate of clinically relevant migration as defined by stent migration followed by reintervention via endoscopy for stent replacement is unknown. The goal of this study is to gain insight into the total migration rate and clinically relevant migration rate of different types of FCSEMS placed within benign and malignant strictures with specific attention paid to stent manufacturer, diameter, and length. Patients and methods Multicenter retrospective analysis of endoscopic data from patients with FCSEMS placed within benign or malignant strictures. FCSEMS used included a variety of sizes and manufacturers. Results A total of 369 patients were included, 161 of whom had benign strictures and 208 of whom had malignant strictures. The total migration rate and clinically relevant migration rate in benign strictures were 30 % and 17 %, respectively. For benign strictures, Wallflex stents had a clinically relevant migration rate of 15 %, compared to Endomaxx stents with 19 %, and Evolution stents with 25 % (P = 0.52). The total migration rate and clinically relevant migration rates in malignant strictures were 23 % and 14 %, respectively. Evolution stents had a significantly higher clinically relevant migration rate (29 %) than the Wallflex stents (7 %) and the endomaxx stents (12 %), P = 0.003. Conclusion This study is the largest to investigate migration rates for FCSEMS in benign and malignant strictures. Clinically relevant migration is a relatively common occurrence with all stent types studied and better anti-migration features are needed.

Summary Esophageal stents are widely used for the palliation of malignant esophageal obstruction. Advances in technology have made esophageal stenting technically feasible and widespread for such obstruction, but complications remain frequent. We present outcomes of a large cohort undergoing esophageal stent placement for malignant esophageal obstruction at a tertiary care cancer center. Patients who underwent placement of esophageal stents for malignancy-related esophageal obstruction between 1 January 2001 and 31 July 2020 were identified. Exclusion criteria included stents placed for benign stricture, fistulae, obstruction of proximal esophagus (proximal to 24 cm from incisors), or post-surgical indications. Patient charts were reviewed for demographics, procedure and stent characteristics, complications, and follow-up. A total of 242 patients underwent stent placement (median age: 64 years, 79.8% male). The majority, 204 (84.3%), had esophageal cancer. During the last two decades, there has been an increasing trend in the number of esophageal stents placed. Though plastic stents were previously used, these are no longer utilized. Complications are frequent and include early complications of pain in 68 (28.1%) and migration in 21 (8.7%) and delayed complications of recurrent symptoms of dysphagia in 46 (19.0%) and migration in 26 (10.7%). Over the study period, there has not been a significant improvement in the rate of complications. During follow-up, 92 (38%) patients required other enteral nutrition modalities after esophageal stent placement. No patient, treatment, or stent characteristics were significantly associated with stent complication or outcome. Esophageal stent placement is an increasingly popular method for palliation of malignant dysphagia. However, complications, particularly pain, migration, and recurrent symptoms of dysphagia are common. Almost 40% of patients may also require other methods of enteral access after esophageal stent placement. Given the high complication rates and suboptimal outcomes, removable stents should be considered as first-line in the case of poor palliative response.

Introduction. Colonic obstruction is one of the manifestations of colon cancer for which self-expanding metal stents (SEMS) have been effectively used, to restore the luminal patency either for palliative care or as a bridge to resective surgery. The aim of our study is to evaluate the efficacy and safety of large diameter SEMS in patients with malignant colorectal obstruction.Methods and Results. A four-year retrospective review of the Medical Archival System was performed and identified 16 patients. The average age was 70.8 years, of which 56% were females. The most common cause of obstruction was colon cancer (9/16, 56%). Rectosigmoid was the main site of obstruction (9/16) and complete obstruction occurred in 31% of cases. The overall technical and clinical success rates were 100% and 87%, respectively. There were no immediate complications (<24 hours), but stent stenosis due to kinking occurred within one week of stent placement in 2 patients. Stent migration occurred in 2 patients at 34 and 91 days, respectively. There were no perforations or bleeding complications.Conclusion. Large diameter SEMS provide a safe method for palliation or as a bridge to therapy in patients with malignant colonic obstruction with high technical success and very low complication rates.

Background: Bilateral total knee arthroplasty (BTKA) procedures are associated with an increased risk of complications when compared with unilateral approaches. In 2006, in an attempt to reduce this risk, our institution implemented selection criteria that specified younger and healthier patients as candidates for BTKA. Questions/Purpose: We sought to investigate the effect of these selection criteria on perioperative outcomes. Methods: In a retrospective cohort study, we used institutional data to identify patients who underwent BTKA between 1998 and 2014. Patients were divided into 2 groups: those who underwent surgery before the 2006 introduction of our selection criteria (1998–2006) and those who underwent surgery after (2007–2014). Groups were compared in terms of demographics, comorbidity burden, and incidence of perioperative complications. Regression analysis was performed, calculating incidence rate ratios to evaluate changes in complication rates. Results: Before the selection criteria were implemented in 2006, patients who underwent BTKA were older and had a higher comorbidity burden. The rate of major complications per 1000 hospital days decreased from 31.5 in 1998 to 7.9 in 2014. A reduction in cardiac complications was the most significant contributor to this decrease in major complications. Conclusion: After stringent criteria for BTKA candidates were implemented at our institution, selection of younger patients with lower comorbidity burden was accompanied by a reduction in the incidence of operative complications. This suggests that introducing such criteria can be associated with a reduction in adverse perioperative outcomes.

A thread-fix stent entails long hospitalization and patient discomfort. We aimed to evaluate the efficacy of a novel stent with silicone-covered outer double layers without external fixation (Beta stent) for anastomotic leakage after total or proximal gastrectomy. The outcomes were compared between gastric cancer patients who underwent stent placement using a thread-fix stent between 2014 and 2015 (Thread-Fix Group) and those who received a Beta stent in the succeeding period until October 2018 (Beta Stent Group). The Beta Stent Group (n = 14) had a significantly higher leakage healing rate by the first stent placement (92.9% vs. 53.8%; p = 0.021) and had a shorter hospitalization period (median: 16 days vs. 28 days; p = 0.037) than the Thread-Fix Group (n = 13). Further, 50% of the Beta stent patients received outpatient management until stent removal. Stent maintenance duration was significantly longer in the Beta Stent Group (median, 28 days vs. 18 days; p = 0.006). There was no significant between-group difference in stent-related complications except for stent migration (7.1% (Beta Stent Group) vs. 0% (Thread-Fix Group), p = 0.326). In conclusion, the Niti-S Beta stent is an effective treatment for anastomotic leakage from total or proximal gastrectomy for gastric cancer. Stent maintenance is possible without hospitalization.

Biliary Strictures

Context Biliary strictures after liver transplantation are recognized as its Achilles’ heel. The strictures are classified in anastomotic and ischemic or non-anastomotic biliary strictures, and they figure among the most common complications after liver transplantation. There are some treatment options including balloon dilation, the placement of multiple plastic stents and the placement of self-expandable metal stents and all of them seem to have good results. Objectives The aim of this study was to systematically review the literature concerning the results of the endoscopic treatment of anastomotic biliary strictures after liver transplantation. Methods A systematic review of the literature was performed on the management of anastomotic biliary strictures post- orthotopic liver transplantation. The Medline-PubMed, EMBASE, Scielo-LILACS, and Cochrane Databases were electronically searched from January 1966 to April 2013. Results No well-designed randomized controlled trial was found. Most studies were retrospective or prospective comparisons in design. One study (86 patients) compared the endoscopic and the percutaneous accesses. The sustained clinical success rates were similar but the treatment duration was longer in the percutaneous group access. Two studies (56 patients) compared balloon dilation with balloon dilation and multiple plastic stents. There were no differences concerning sustained clinical success and complication rates. Conclusions Balloon dilation is as effective as balloon dilation plus multiple plastic stenting for the resolution of the anastomotic biliary strictures. Well-designed randomized trials are still needed to compare balloon dilation versus multiple plastic stenting versus metallic stenting.

Duodenal stenting has been widely used on malignant pathology on selected patients with poor prognosis and advanced disease. In these last years, there has been a clear ampliation of the clinical applications of endoscopy procedures and stents. Its use on benign pathology is spreading but there is a lack of literature about the complications in this context. The incidence of stent migration is about 10-25% in self-expandable metal stent (SEMS), and 2-5% on covered self-expanding metal stents (CSEMS). We reported a clinical case of a 48 years old patient who developed a duodenal ulcer. The patient was submitted to exploratory laparotomy, with duodenal primary closure of the ulcer. Later, the patient developed a enterocutaneous fistula because of the duodenal leak. It was referred to our third level hospital to the hepatopancreatobiliary surgery service. A new exploratory laparotomy with duodenal exclusion was planned, but it was impossible to access due to frozen abdomen. CSEMS was placed in the duodenal bulb resulting in the resolution of leaking, but the stent could not be removed because of migration. The stent trajectory was followed by abdominal x ray and tomography. The patient developed multiple intestinal an fecal enterocutaneous fistulas. It was submitted to multiples endoscopies, colonoscopies and enteroscopy without any success to reaching it. It was decided to perform a right lumbotomy to extract the prothesis. The stent was surgically removed, a planned stoma was left on the right flank on the extraction site.
