Abstract
BACKGROUND AND AIMS Sarcopenia is an important prognostic factor for cancer patients. The aim of this study was to assess the ability of sarcopenia to predict recurrent biliary obstruction (RBO) in patients with unresectable cancer after EUS-guided biliary drainage (EUS-BD). METHODS The study enrolled 113 patients who underwent EUS-BD using the self-expandable metal stent (SEMS) for unresectable malignant biliary obstruction (MBO) between April 2016 and December 2021 at Wakayama Medical University Hospital. The skeletal muscle index at the third lumbar spine level (L3) was calculated from computed tomography images. We analyzed the cumulative incidence of RBO at 180 days after stent insertion. Univariate and multivariate analyses were performed to identify variables significantly associated with RBO. RESULTS Seventy-six patients were assigned to the sarcopenia group, and 37 were assigned to the non-sarcopenia group. The 180-day cumulative incidence of RBO was 11% in the non-sarcopenia group and 29% in the sarcopenia group (p = 0.034). The time to RBO was significantly shorter for the sarcopenia group (p = 0.028; Gray's test). Multivariate analyses identified sarcopenia as an independent prognostic factor for RBO (present vs absent; HR 4.61; 95% CI 1.76-12.10, p = 0.001). The rates of biliary sludge/food impaction were significantly higher in the sarcopenia group for the causes of RBO (p = 0.048). There were no significant differences between the sarcopenia and the non-sarcopenia groups with respect to related EUS-BD adverse events. CONCLUSION Sarcopenia is an independent indicator of RBO in patients with MBO who receive EUS-BD with SEMS.

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

Abstract
BACKGROUND Acute cholecystitis is a significant adverse event after self-expandable metal stent (SEMS) placement for malignant biliary obstruction (MBO); however, no appropriate treatment strategy has been established for its management. AIMS This study aimed to examine the feasibility and utility of endoscopic ultrasound-guided naso-gallbladder drainage (EUS-NGBD) for the management of acute cholecystitis occurring after SEMS placement. METHODS This retrospective study investigated consecutive patients with acute cholecystitis after SEMS placement for unresectable MBO, in whom EUS-NGBD was attempted. The study outcomes included technical success, clinical success, procedure time, adverse event, and cholecystitis recurrence, associated with the procedure. RESULTS During the study period, EUS-NGBD was performed for SEMS-related acute cholecystitis in 30 patients with MBO. The technical and clinical success rates were 96.7% (29/30) and 96.6% (28/29), respectively. The median procedure time was 15 min, and rate of procedure-related adverse event was 3.3% (1/30). The median duration from the procedure to tube removal was 9 days. No adverse events were observed after removal. The median hospitalization duration after the procedure was 14 days, and the median duration to the (re-)start of chemotherapy from cholecystitis onset was 13 days. The median overall survival after EUS-NGBD was 123 days, and the rate of cholecystitis recurrence until death was 4.2% (1/28). CONCLUSIONS This study demonstrated that EUS-NGBD possesses good technical and clinical feasibility with an acceptable adverse event rates and short hospitalization and chemotherapy withdrawal period. Therefore, EUS-NGBD may be a good option for the treatment of SEMS-related cholecystitis in patients with MBO.

Abstract
BACKGROUND A self-expandable metal stent is often placed as a bridge to elective surgical treatment of left-sided malignant obstruction of the colon because it allows for primary anastomosis without the need for a temporary stoma, which has a positive impact on the patient's quality of life. However, although a relatively safe procedure, colonic stenting can have complications that require emergency surgery. This case report describes a rare case of abdominal compartment syndrome that occurred as a complication of endoscopic insufflation during colonic stenting. CASE PRESENTATION The patient was a 72-year-old woman who presented complaining of several days of constipation and loss of appetite. Computed tomography of the abdomen revealed obstruction of the sigmoid colon by a tumor. There were no symptoms or computed tomography findings to suggest perforation. Therefore, an attempt was made to insert a self-expandable metal stent. Acute respiratory disturbance and a change in consciousness occurred during the stenting procedure, with marked abdominal distention. Abdominal compartment syndrome was diagnosed and treated by decompressive laparotomy. CONCLUSIONS To the best of our knowledge, this is the first reported case of abdominal compartment syndrome as a complication of endoscopic insufflation during colonic stenting. The possibility of abdominal compartment syndrome should be considered if acute respiratory disturbance or altered consciousness occurs during endoscopic procedure in a patient with malignant bowel obstruction.

Abstract
Endoscopic therapy is the first line of management for chronic pancreatitis (CP)-related benign biliary strictures. Multiple plastic stents (MPS) exchanged at regular intervals and temporary placement of fully covered self-expanding metal stents (FCSEMS) are preferred modalities of endotherapy. FCSEMS placement is non-inferior to MPS and requires fewer sessions of endoscopic retrograde cholangiopancreatography than MPS placement. The presence of head calcifications, severe CP, and length of stricture are predictors of failure or recurrence after endotherapy. Failure of endotherapy should be considered after 1 year when surgery should be considered.

Abstract
BACKGROUND AND GOALS: Gastric outlet obstruction (GOO) usually occurs at the pylorus or the duodenum through primary gastric, duodenal, or pancreatic tumors. However, metastatic GOO is relatively rare. Although self-expandable metal stent (SEMS) placement is often performed as an alternative and practical palliative approach for primary GOO, there are few reports of metastatic GOO treatment with SEMS. This study aimed to investigate the efficacy, safety, stent patency, and complications of SEMS for treating primary and metastatic GOO. METHODS The data of 42 patients with GOO who received SEMS from November 2016 to April 2022 were reviewed retrospectively. Patients were divided into primary group (n = 25) and metastatic group (n = 17) according to the cause of GOO. The rates of technical and clinical success, stent patency, and complications were compared between the two groups. RESULTS The overall technical and clinical success rates were 97.9% and 93.5%, respectively. The total SEMS implantation time was 48.2 ± 33.5 (10.0-140.0) minutes. The primary technical success rate was 100.0% in both primary and metastatic groups, and the primary clinical success rate was 96.0% (24/25) in the primary group vs 88.2% (15/17) in the metastatic group (P = 0.350). After reintervention, the secondary technical success rate was 100.0% (27/27) in the primary group vs 95.0% (19/20) in the metastatic group (P = 0.330); and the secondary clinical success rate was 96.3% (26/27) in the primary group vs 89.5% (17/19) in the metastatic group (P = 0.367). No serious complications, such as gastrointestinal perforation, stent migration, bleeding, or aspiration pneumonia, were observed in these patients. CONCLUSIONS SEMS under fluoroscopic guidance is an effective and safe treatment for primary and metastatic GOO. The etiology of obstruction did not influence stent patency or complications. Therefore, stent implantation is recommended for patients with metastatic GOO caused by multiple peritoneal metastases to improve their quality of life.

Abstract
BACKGROUND AND AIMS Self-expandable metallic stents (SEMS) can be used to treat malignant colorectal obstruction (MCO). Guidewire insertion to the proximal site of MCO is the most important step for SEMS placement. However, some patients cannot undergo guidewire insertion because of total obstruction or location at anatomically challenging areas. We report a guidewire insertion technique using an ultrathin endoscope (UTE) in patients with MCO in whom conventional SEMS insertion failed. METHODS This study was a retrospective cohort study conducted at three academic centers in Korea. The medical records of 956 consecutive patients who underwent SEMS placement during 2012-2021 were analyzed. After failing guidewire insertion using a colonoscope, a UTE was inserted. Guidewire insertion was done through the working channel of the UTE. Following guidewire insertion, the endoscope was removed from the patient. While removing the endoscope, the guidewire was advanced to be located at the originally inserted site. Then, the colonoscope was inserted over the guidewire, and SEMS was replaced. RESULTS Conventional SEMS insertion failed in 75 patients. Of these, guidewire insertion using a UTE was tried in 59 patients. The rate of technical success was 91.5% (54/59). Considering all patients, the overall technical success rate of SEMS placement was 97.8% (935/956). This technique increased the technical success rate by 5.6% among the total cohort. CONCLUSIONS The UTE facilitated guidewire insertion and enhanced the overall success rate for SEMS placement. In addition, this technique can be used as a rescue method when guidewire insertion fails using a colonoscope.

Abstract
BACKGROUND Management of anastomotic leaks after Ivor-Lewis esophagectomy remains a challenge. Although intracavitary endoscopic vacuum therapy (EVT) has shown great efficacy for large dehiscences, the optimal management of smaller leaks has not been standardized. This study aims to compare EVT versus self-expandable metal stent (SEMS) in the treatment of leaks < 30 mm in size, due to the lack of current data on this topic. METHODS Patients undergoing EVT (cases) or SEMS (controls) between May 2017 and July 2022 for anastomotic leaks < 3 cm following oncologic Ivor-Lewis esophagectomy were enrolled. Controls were matched in a 1:1 ratio based on age (± 3 years), BMI (± 3 kg/m2) and leak size (± 4 mm). RESULTS Cases (n = 22) and controls (n = 22) showed no difference in baseline characteristics and leak size, as per matching at enrollment. No differences were detected between the two groups in terms of time from surgery to endoscopic treatment (p = 0.11) or total number of procedures per patient (p = 0.05). Remarkably, the two groups showed comparable results in terms of leaks resolution (90.9% vs. 72.7%, p = 0.11). The number of procedures per patient was not significant between the two cohorts (p = 0.05). The most frequent complication in the SEMS group was migration (15.3% of procedures). CONCLUSION EVT and SEMS seem to have similar efficacy outcomes in the treatment of anastomotic defects < 30 mm after Ivor-Lewis esophagectomy. However, larger studies are needed to corroborate these findings.

Abstract
BACKGROUND This study aimed to determine short-term and long-term outcomes according to time intervals after stenting and compared them with those of emergency surgery (ES) in colorectal cancer (CRC) with malignant obstruction. METHODS CRC with malignant obstructions was reviewed retrospectively between January 2008 and July 2018. Of a total of 539 patients who visited the emergency room and underwent ES, 133 were enrolled in the ES group. Of a total of 567 patients who initially received stenting and subsequently underwent elective surgery, 220 were enrolled in the SEMS group. The interval between SEMS placement and elective surgery was classified as < 11 days, 11-17 days, and > 17 days. RESULTS For those who received SEMS (n = 220), those with a time interval of 11-17 days (n = 97) had fewer hospital days than those with a time interval of < 11 days (n = 68) (8 days vs. 15 days) and less stoma formation than those with a time interval of > 17 days (n = 55) (1.0% vs. 14.6%). Multivariable analysis revealed a decreased risk of death for the group with a time interval of 11-17 days (20.6%) compared to the ES group (31.6%) (hazard ratio: 0.48; 95% confidence interval: 0.24-0.97). Disease-free survival was comparable between the SEMS and ES groups regardless of the time interval (log-rank p = 0.52). CONCLUSIONS The time interval of 11-17 days after stenting to elective surgery appeared to be associated with the most favorable outcomes.

Abstract
BACKGROUND Stenosis is one of the most common complications in patients with Crohn's disease (CD). Endoscopic balloon dilation (EBD) is the treatment of choice for a short stenosis adjacent to the anastomosis from previous surgery. Self-expandable metal stents (SEMS) may be a suitable treatment option for longer stenoses. To date, however, there is no scientific evidence as to whether endoscopic (EBD/SEMS) or surgical treatment is the best approach for de novo or primary stenoses that are less than 10 cm in length. METHODS/DESIGN Exploratory study as "proof-of-concept", multicentre, open-label, randomized trial of the treatment of de novo stenosis in the CD; endoscopic treatment (EBD/SEMS) vs surgical resection (SR). The type of endoscopic treatment will initially be with EDB; if a therapeutic failure occurs, then a SEMS will be placed. We estimate 2 years of recruitment and 1 year of follow-up for the assessment of quality of life, costs, complications, and clinical recurrence. After the end of the study, patients will be followed up for 3 years to re-evaluate the variables over the long term. Forty patients with de novo stenosis in CD will be recruited from 15 hospitals in Spain and will be randomly assigned to the endoscopic or surgical treatment groups. The primary aim will be the evaluation of the patient quality of life at 1 year follow-up (% of patients with an increase of 30 points in the 32-item Inflammatory Bowel Disease Questionnaire (IBDQ-32). The secondary aim will be evaluation of the clinical recurrence rate, complications, and costs of both treatments at 1-year follow-up. DISCUSSION The ENDOCIR trial has been designed to determine whether an endoscopic or surgical approach is therapeutically superior in the treatment of de novo stenosis in CD.

Abstract
BACKGROUND Endoscopic placement of a self-expandable metal stent (SEMS) is a minimally invasive treatment for use in malignant and benign colonic obstruction. However, their widespread use is still limited with a nationwide analysis showing only 5.4% of patients with colon obstruction undergoing stent placement. This underutilization could be due to perceived increase risk of complications with stent placement.
AIM To review long- and short-term clinical success of SEMS use for colonic obstruction at our center.
METHODS We retrospectively reviewed all the patients who underwent colonic SEMS placement over a eighteen year period (August 2004 through August 2022) at our academic center. Demographics including age, gender, indication (malignant and benign), technical success, clinical success, complications (perforation, stent migration), mortality, and outcomes were recorded.
RESULTS Sixty three patients underwent colon SEMS over an 18-year period. Fifty-five cases were for malignant indications, 8 were for benign conditions. The benign strictures included diverticular disease stricturing (n = 4), fistula closure (n = 2), extrinsic fibroid compression (n = 1), and ischemic stricture (n = 1). Forty-three of the malignant cases were due to intrinsic obstruction from primary or recurrent colon cancer; 12 were from extrinsic compression. Fifty-four strictures occurred on the left side, 3 occurred on the right and the rest in transverse colon. The total malignant case (n = 55) procedural success rate was 95% vs 100% for benign cases (P = 1.0, NS). Overall complication rate was significantly higher for benign group: Four complications were observed in the malignant group (stent migration, restenosis) vs 2 of 8 (25%) for benign obstruction (1-perforation, 1-stent migration) (P = 0.02). When stratifying complications of perforation and stent migration there was no significant difference between the two groups (P = 0.14, NS).
CONCLUSION Colon SEMS remains a worthwhile option for colonic obstruction related to malignancy and has a high procedural and clinical success rate. Benign indications for SEMS placement appear to have similar success to malignant. While there appears to be a higher overall complication rate in benign cases, our study is limited by sample size. When evaluating for perforation alone there does not appear to be any significant difference between the two groups. SEMS placement may be a practical option for indications other that malignant obstruction. Interventional endoscopists should be aware and discuss the risk for complications in setting of benign conditions. Indications in these cases should be discussed in a multi-disciplinary fashion with colorectal surgery.

Abstract
BACKGROUND Digestive tract reconstruction is required after the surgical resection of a colorectal malignant tumor. Some patients may have concomitant anastomotic complications, such as anastomotic stenosis with fistula (ASF), postoperatively. Therefore, we evaluated the efficacy and safety of endoscopic fully covered self-expandable metal stent and homemade vacuum sponge-assisted drainage (FSEM-HVSD) for the treatment of ASF following the radical resection of colorectal cancer. METHODS Patients treated with FESM-HVSD were prospectively analyzed and followed up for ASF following colorectal cancer treatment in our medical center from 2017 to 2021 for the observation and evaluation of its safety and efficacy. RESULTS Fifteen patients with a mean age of 55.80 ± 11.08 years were included. Nine patients (60%) underwent protective ileostomy. All 15 patients were treated with endoscopic FSEM-HVSD. The median time from the index operation to the initiation of FSEM-HVSD was 80 ± 20.34 days in patients who underwent protective ileostomy versus 11.4 ± 4.4 days in those who did not. The average number of endoscopic treatments per patient was 5.70 ± 1.25 times. The mean length of hospital stay was 27.60 ± 4.43 days. FSEM-HVSD treatment was successful in 13 patients, and no patients had any complications. The follow-up time was 1 year. Twelve of 15 (80%) patients achieved prolonged clinical success after FSEM-HVSD treatment, 1 experienced anastomotic tumor recurrence and underwent surgery again, and 1 patient required balloon dilation for anastomotic stenosis recurrence. CONCLUSIONS FSEM-HVSD is an effective, safe, and minimally invasive treatment for ASF following colorectal cancer treatment. This technique could be the preferred treatment strategy for patients with ASF.

Abstract
A 69-year-old man was referred to our hospital with obstructive jaundice. A tumor with poor contrast enhancement was found in the pancreatic head, but there was no evidence of pancreatic atrophy, irregular stenosis, or dilation of the main pancreatic duct. He was diagnosed with borderline resectable pancreatic cancer with distal malignant biliary obstruction. After plastic stent placement, serum bilirubin levels improved, and chemotherapy was started. However, he developed cholangitis; thus, the plastic stent was replaced with a covered self-expandable metallic stent. He subsequently developed a delayed pancreatic fistula due to main pancreatic duct disruption. An endoscopic nasopancreatic duct drainage tube was placed to bridge the main pancreatic duct disruption after removing the covered self-expandable metallic stent. In addition, endoscopic ultrasound-guided transmural drainage was performed for the infected fluid collection caused by the pancreatic fistula, and the clinical symptoms quickly improved. This case presents the possibility of a delayed pancreatic fistula due to self-expandable metallic stent deployment. The need for considering such delayed complications when placing self-expanding metallic stents is highlighted.

Abstract
Self-expandable metal stent (SEMS) for malignant colorectal obstruction is widely used as a bridge to elective surgery or palliative treatment. However, with the increasing use of SEMS for treatment, complication rates associated with stents have been raised as a concern. We experienced a rare migration-related complication that a stent partially migrated out of the anus with an incarceration. A 62-year-old man was admitted with sigmoid malignant obstruction. Due to multiple metastases, he refused to undergo colostomy, and an uncovered SEMS was placed. Subsequently, he started chemotherapy. Seven months after placement, the stent migrated into the rectum. After unsuccessful attempts to extract the stent, he sought our assistance. We observed that half of the stent was outside the anus, and a 15 mm lump of mucosa was embedded in the proximal end of the stent. After several attempts, we successfully removed the SEMS. Stent incarceration following migration is not a common occurrence, but it serves as a reminder that clinicians need to be more vigilant about complications that may arise after stent implantation. We describe this unusual complication and share our experience about the removal of the stent.

Abstract
BACKGROUND Outcomes of partially covered self-expandable metal stents (SEMS) as an additional stent after recurrent duodenal obstruction (RDO) have not been elucidated. In this study, we compared outcomes of partially covered and uncovered SEMS placement after RDO in patients with malignant duodenal obstruction and explored factors affecting re-recurrent obstruction and overall survival in this population. METHODS We conducted a retrospective study of patients undergoing SEMS placement for RDO at a cancer institute in Japan from July 2014 to June 2021. Clinical variables and outcomes of patients undergoing partially covered and uncovered SEMS placement were compared. RESULTS Sixty-one patients underwent SEMS placement after RDO, for which the COMVI stent was used in 38 cases and uncovered stents were used in 23 cases. Stent ingrowth was the most common cause of RDO (51.4%). Stent migration only occurred after partially covered stent placement (20% vs. 0%, p = 0.018). Choice of SEMS had no impact on time to re-RDO (median 2.8 vs. 4.1 months, p = 0.776) or overall survival (median 2.6 vs. 2.4 months, p = 0.703). Median overall survival was longer in patients receiving chemotherapy after second stenting (4.6 vs. 1.8 months, p < 0.001) and shorter in those with early RDO, regardless of the SEMS used. Use of the partially covered stent had no impact on survival or time to RDO. CONCLUSIONS While outcomes after partially covered SEMS placement for RDO were not significantly different from uncovered SEMS, migration remains a concern when they are used as a second stent. Chemotherapy after second stenting was associated with longer overall survival but not with longer time to re-RDO.

Abstract
Approximately 7%-29% of patients with colorectal cancer present with colonic obstruction. The concept of self-expandable metal stent (SEMS) insertion as a bridge to surgery (BTS) is appealing. However, concerns on colonic stenting possibly impairing oncologic outcomes have been raised. This study aimed to review current evidence on the short- and long-term oncologic outcomes of SEMS insertion as BTS for left-sided malignant colonic obstruction. For short-term outcomes, colonic stenting facilitates a laparoscopic approach, increases the likelihood of primary anastomosis without a stoma, and may decrease postoperative morbidity. However, SEMS-related perforation also increases local recurrence and impairs overall survival. Moreover, colonic stenting may cause negative oncologic outcomes even without perforation. SEMS can induce shear forces on the tumor, leading to increased circulating cancer cells and aggressive pathological characteristics, including perineural and lymphovascular invasion. The conflicting evidence has led to discordant guidelines. Well-designed collaborative studies that integrate both oncologic outcomes and data on basic research (e.g., alteration of circulating tumors) are needed to clarify the actual benefit of colonic stenting as BTS.

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
Little is known about the efficacy and safety of esophageal stents for the management of esophageal strictures in children and adolescents. A systematic review was performed to assess the efficacy and safety of esophageal stents for the management of benign esophageal strictures in children and adolescents. Observational studies related to the examination of esophageal stents in pediatrics were extracted using the original databases by December 2021. We found 18 retrospective and prospective studies with a total of 340 children and adolescents. Overall, our findings show that different therapeutic modalities based on esophageal stents were offered to children and adolescents for various indications, in which most studies reported successful cases, although ineffective claims cannot be ignored. Fully covered self-expandable metal stent, self-expandable metal stent, and silastic esophageal stent were the stent types most used, although different materials and prototypes were reported as well. The number of stents used per patient and the duration of the stenting therapy varied widely (ranging from 1 to 584 days). Such treatments were not standardized because of different factors, such as different tolerance to complications in subjects aged 1 month and 16 years, frequent stent migration requiring removal followed or not by its replacement, different guides provided by each stent manufacturer, and successful healing of esophageal lesions. Different esophageal stents may be a reasonable therapeutic approach for the management of benign esophageal strictures in children and adolescents. We believe that esophagus-sparing methods like stents represent a promising alternative or adjunctive treatment to be considered in pediatrics.

Abstract
BACKGROUND Endoscopic radiofrequency ablation (RFA) is expected to prolong stent patency for malignant biliary obstruction (MBO). However, its feasibility when used in conjunction with a balloon enteroscope (BE) in patients with surgically altered anatomy (SAA) remains unknown. AIMS This study aimed to investigate the feasibility of RFA combined with metal stent insertion under BE guidance for MBO in patients with SAA. METHODS Thirty-seven patients who underwent treatment between October 2016 and January 2021 and met the eligibility criteria were investigated retrospectively. Study outcomes included technical and clinical success, recurrent biliary obstruction (RBO), and other adverse events besides RBO associated with RFA with metal stent placement using BE. RESULTS Technical and clinical success rates were 100% (37/37) each. The rates of early and late adverse events were 8.1% (3/37) and 8.1% (3/37), respectively. RBO occurred in 32.4% (12/37) of the patients, and the median time to RBO was 296 days. The cause of RBO was ingrowth in eight patients, overgrowth in three patients, and indeterminate in one patient. All reinterventions for RBO were successful using the BE approach; all ingrowths, except one, were recanalized using additional RFA without additional stent placement. The frequency of reintervention-related adverse events was 9.1% (1/11). The median time to RBO after reintervention was 166 days. CONCLUSIONS This study demonstrated the technical safety and feasibility as well as good long-term outcomes of endobiliary RFA combined with metal stent placement under BE guidance. This approach may be a useful option for treating MBO in patients with SAA.

Abstract
BACKGROUND The impacts of chemotherapy on patients with malignant gastrointestinal obstructions remain unclear, and multicenter evidence is lacking.
AIM To evaluate the effectiveness and safety of chemotherapy in patients with unresectable malignant gastrointestinal obstructions.
METHODS We conducted a multicenter retrospective cohort study that compared the chemotherapy group who received any chemotherapeutics after interventions, including palliative surgery or self-expandable metal stent placement, for unresectable malignant gastrointestinal obstruction vs the best supportive care (BSC) group between 2014 and 2019 in nine hospitals. The primary outcome was overall survival, and the secondary outcomes were patency duration and adverse events, including gastrointestinal perforation and gastrointestinal bleeding.
RESULTS In total, 470 patients in the chemotherapy group and 652 patients in the BSC group were analyzed. During the follow-up period of 54.1 mo, the median overall survival durations were 19.3 mo in the chemotherapy group and 5.4 mo in the BSC group (log-rank test, P < 0.01). The median patency durations were 9.7 mo [95% confidence interval (CI): 7.7-11.5 mo] in the chemotherapy group and 2.5 mo (95%CI: 2.0-2.9 mo) in the BSC group (log-rank test, P < 0.01). The perforation rate was 1.3% (6/470) in the chemotherapy group and 0.9% (6/652) in the BSC group (P = 0.567). The gastrointestinal bleeding rate was 1.5% (7/470) in the chemotherapy group and 0.5% (3/652) in the BSC group (P = 0.105).
CONCLUSION Chemotherapy after interventions for unresectable malignant gastrointestinal obstruction was associated with increased overall survival and patency duration.

Abstract
Background Self-expandable metal stent (SEMS) placement is commonly used as a bridge to surgery (BTS) for left-sided malignant colorectal obstruction (MCO). However, the optimal time interval between BTS stenting and surgery for left-sided MCO is unclear, and the results of previous studies are conflicting. This study aimed to determine the differences in clinical outcomes according to the time interval between BTS stenting and surgery in left-sided MCO. Methods Data from 594 patients who underwent SEMS placement for MCO between January 2009 and December 2018 were reviewed. Among them, 148 patients who underwent SEMS placement as BTS treatment and curative surgery were enrolled. The enrolled patients were divided into three groups according to the interval between BTS stenting and surgery: group 1 (interval ≤2 weeks), group 2 (interval 2–3 weeks), and group 3 (interval >3 weeks). Results Group 2 and 3 patients underwent significantly higher rates of laparoscopic surgery than those in group 1 (83.7, 81.0 vs. 53.2 %, respectively; P=0.003, P=0.003, respectively). Also, rates of stoma formation directly after resection were significantly higher in group 1 compared to groups 2 and 3 (21.3 vs 2.3, 6.9%, respectively; P=0.008, P=0.043, respectively). Bridging interval had no effect on SEMS-related complications, resection-related complications, 90-day mortality, permanent stoma formation, 3-year disease-free survival, and 3-year overall survival. Conclusions A bridging interval of > 2 weeks between BTS stenting and surgery for left-sided MCO is preferable for lower stoma formation rates and higher rates of laparoscopic approach operation, with no difference in short-term and long-term outcomes including complication, mortality, and survival.

Abstract
Objective To assess the safety and clinical efficacy of percutaneous transhepatic enteral stent placement for recurrent malignant obstruction in patients with surgically altered bowel anatomy. Materials and Methods Between July 2009 and May 2019, 36 patients (27 men and 9 women; mean age, 62.7 ± 12.0 years) underwent percutaneous transhepatic stent placement for recurrent malignant bowel obstruction after surgery. In all patients, conventional endoscopic peroral stent placement failed due to altered bowel anatomy. The stent was placed with a transhepatic approach for an afferent loop obstruction (n = 27) with a combined transhepatic and peroral approach for simultaneous stent placement in afferent and efferent loop obstruction (n = 9). Technical and clinical success, complications, stent patency, and patient survival were retrospectively evaluated. Results The stent placement was technically successful in all patients. Clinical success was achieved in 30 patients (83.3%). Three patients required re-intervention (balloon dilatation [n = 1] and additional stent placement [n = 2] for insufficient stent expansion). Major complications included transhepatic access-related perihepatic biloma (n = 2), hepatic artery bleeding (n = 2), bowel perforation (n = 1), and sepsis (n = 1). The 3- and 12-months stent patency and patient survival rates were 91.2%, 66.5% and 78.9%, 47.9%, respectively. Conclusion Percutaneous enteral stent placement using transhepatic access for recurrent malignant obstruction in patients with surgically altered bowel anatomy is safe and clinically efficacious. Transhepatic access is a good alternative route for afferent loop obstruction and can be combined with a peroral approach for simultaneous afferent and efferent loop obstruction.

Abstract
BACKGROUND AND AIM Fully covered self-expandable metal stents (FCSEMSs) have been increasingly used in the management of benign or malignant biliary disorders. However, the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) with transpapillary placement of the FCSEMS remains controversial. This study therefore aimed to investigate the risk of PEP in patients who received FCSEMS implantation. METHODS In total, 602 patients who underwent endoscopic transpapillary FCSEMS placement at five Chinese medical centers, between 2011 and 2018, were included in this retrospective study. Patients who were younger than 18 years and with stent placement above the papilla were excluded from the study. PEP and the risk factors were reviewed. RESULTS PEP occurred in 56 (9.3%) patients, and eight (1.3%) of them experienced moderate-to-severe PEP. The incidence of PEP rose to 14.6% (51/349) when patients had no pancreatic duct (PD) dilation, and even to 18.6% if no prophylactic approaches were adopted. Prophylactic PD stenting showed better efficacy in reducing the incidence of PEP than did rectal use of indomethacin (3.5% vs 10.8%, P = 0.023). Multivariate logistic regression revealed that difficult cannulation (OR 2.837, 95% CI 1.245-6.465, P = 0.013), PD dilation (OR 0.145, 95% CI 0.05-0.422, P < 0.001), and PD stenting (OR 0.247, 95% CI 0.089-0.686, P = 0.007) were significantly associated with PEP risk. Post-procedure cholecystitis was found in 4.0% of patients. CONCLUSION The risk of post-procedure pancreatitis is modestly increased in patients receiving transpapillary FCSEMS placement, particularly when there is absence of PD dilation. Thus, prophylactic pancreatic stenting is recommended in such a condition.

Abstract
Gastrointestinal leaks and fistulae are serious, potentially life threatening conditions that may occur with a wide variety of clinical presentations. Leaks are mostly related to post-operative anastomotic defects and are responsible for an important share of surgical morbidity and mortality. Chronic leaks and long standing post-operative collections may evolve in a fistula between two epithelialized structures. Endoscopy has earned a pivotal role in the management of gastrointestinal defects both as first line and as rescue treatment. Endotherapy is a minimally invasive, effective approach with lower morbidity and mortality compared to revisional surgery. Clips and luminal stents are the pioneer of gastrointestinal (GI) defect endotherapy, whereas innovative endoscopic closure devices and techniques, such as endoscopic internal drainage, suturing system and vacuum therapy, has broadened the indications of endoscopy for the management of GI wall defect. Although several endoscopic options are currently used, a standardized evidence-based algorithm for management of GI defect is not available. Successful management of gastrointestinal leaks and fistulae requires a tailored and multidisciplinary approach based on clinical presentation, defect features (size, location and onset time), local expertise and the availability of devices. In this review, we analyze different endoscopic approaches, which we selected on the basis of the available literature and our own experience. Then, we evaluate the overall efficacy and procedural-specific strengths and weaknesses of each approach.

Abstract
BACKGROUND/AIM Self-expandable metal stent (SEMS) as a bridge to surgery (BTS) for obstructive colorectal cancer (CRC) raises concerns regarding the short-term as well as oncological outcome. The present study aimed to investigate the safety of SEMS placement and risk factors of worse short-term and oncological outcomes as BTS. PATIENTS AND METHODS Twenty-four patients with obstructive CRC who underwent SEMS placement as BTS were included. Success rate of SEMS placement and 2-year relapse-free survival (RFS) rates in stage II/III BTS patients were assessed. RESULTS Technical and clinical success rates for SEMS placement were 100% and 87.5%, respectively. In Multivariate analyses, longer tumour length, longer interval to surgery, and angular positioning were risk factors related with the complication of stent placement. Two-year RFS rates were significantly higher in the no-complication than in the complication group (100% vs. 75%, log-rank test, p<0.01). CONCLUSION A long tumour length, long interval between SEMS insertion and surgery, and angular positioning of the SEMS were identified as risk factors for SEMS-related complications. Moreover, SEMS insertion and/or surgery complications were associated with worse oncological outcome in CRC patients.

Abstract
PURPOSE Whether deferring surgery after endoscopic self-expandable metal stent (SEMS) placement for neoplastic stricture, and operating patients in a quasi-elective situation, may result in similar oncologic outcomes to elective operations is unclear. This study aimed to evaluate the disease-free survival (DFS) rates of patients who underwent an interval colon resection after SEMS placement or an elective operation with comparable cancer stages. METHODS From a prospective dataset, we retrospectively selected patients with the following characteristics: (1) left-sided colon cancer and (2) cancer stage I to III. Exclusion criteria were as follows: (1) palliative surgery and (2) emergency operation. Then we stratified patients into two groups: (A) full-elective left colon resection and (B) quasi-elective left colon resection, defined as surgery performed after SEMS placement for obstructive colon cancer. DFS function was studied by the Kaplan-Meier method. RESULTS After 1:2 matching based on cancer stage, 106 patients of the group A were compared with 53 patients of group B. In each group, there were 9.4% of stage I, 39.4% of stage II, and 50.9% of stage III patients. The rate of technical failure in SEMS placement was 3.8%. After a mean follow-up of 54 months, 16 (15.1%) patients in the full-elective groups and 10 (18.9%) in the quasi-elective group experience cancer recurrence (log rank = 0.588). DFS curve did not reach the median value. CONCLUSIONS SEMS placement with interval colon resection for obstructive neoplastic strictures seems to provide similar long-term oncologic outcomes to operations performed in an elective setting when a low rate of technical failure is achieved.

Abstract
Advanced colorectal cancer can cause acute colonic obstruction, which is a life-threatening condition that requires emergency bowel decompression. Malignant colonic obstruction has traditionally been treated using emergency surgery, including primary resection or stoma formation. However, relatively high rates of complications, such as anastomosis site leakage, have been considered as major concerns for emergency surgery. Endoscopic management of malignant colonic obstruction using a self-expandable metal stent (SEMS) was introduced 20 years ago and it has been used as a first-line palliative treatment. However, endoscopic treatment of malignant colonic obstruction using SEMSs as a bridge to surgery remains controversial owing to short-term complications and longterm oncological outcomes. In this review, the current status of and recommendations for endoscopic management using SEMSs for malignant colonic obstruction will be discussed.

Abstract
A covered self-expandable metal stent is an efficient and established tool for solution of biliary obstruction. The use of multiple fully covered self-expandable metal stents (SEMSs) for distal malignant biliary obstruction has never been reported. The first case, a 33-year-old female with pancreatic head cancer had low bifurcation of the hepatic ducts and developed obstructive cholangitis by the first single SEMS. The second case, a-59-year-old female with pancreatic head cancer repeatedly underwent biliary decompression by a single SEMS (10-mm, 12-mm), because placed SEMSs were repeatedly dislocated. For solving these problems, we performed side-by-side placement of covered self-expandable metal stents. Finally, side-by-side placement of SEMSs across the papilla for distal malignant biliary obstruction was feasible and available for the two cases.

Abstract
The role of endoscopic retrograde cholangiopancreatography (ERCP) has dramatically changed in the last years, mainly into that of a therapeutic procedure. The treatment of benign biliary disease, like “difficult” choledocolithiasis, with endoscopic papillary large balloon dilation combined with endoscopic sphinterotomy has proven an effective and safe technique. Moreover, safety in ERCP has improved as well, with the prevention of post-ERCP pancreatitis and patient-to-patient transmission of infections. The advent of self-expandable metal stenting has radically changed the management of biliopancreatic malignant strictures, while the role for therapy of benign strictures is still controversial. In addition, cholangioscopy (though the direct visualization of the biliopancreatic ductal system) has allowed for characterization of indeterminate biliary strictures and facilitated rescue therapy of large biliary stones deemed removable. Encouraging data from tissue ablation techniques, such as photodynamic therapy and radiofrequency ablation, need to be confirmed by large sample size clinical controlled trials. On the other hand, we have no drug-coated stents yet available to implant and evidence for the use of biodegradable stents is still weak. The competency and privileging of ERCP and endoscopic ultrasonography have been analyzed longer but the switch between the two procedures, at the same time, is becoming ordinary; as such, the endoscopist interested in this field should undergo parallel edification through training plans. Finally, the American Society for Gastrointestinal Endoscopy’s statement on non-anesthesiologist administration of propofol for gastrointestinal endoscopy is not actually endorsed by the European Society of Anaesthesiology, having many medical-legal implications in some European countries.

Abstract
OBJECTIVE Compare efficacy, safety and long-term outcomes of bridge-to-surgery and emergency surgery in acute malignant colorectal obstruction. METHODS Retrospective study of 94 consecutive patients with left-sided acute malignant colorectal obstruction treated with curative intent between 2010-2017. RESULTS 48 patients underwent stent placement and 46 underwent emergency surgery. Technical and clinical success were 100% and 87%. Laparoscopy and one-staged operation were more frequent in bridge-to-surgery (44% vs 2%, p < 0.001; 73% vs 30%, p < 0.001). Fewer permanent stomas were created in bridge-to-surgery (15% vs 35%, p = 0.013). Overall morbidity was 36%. Immediate and post-procedure stent related-complications occurred in 6% and 13%; surgery-related complications occurred in 28% (bridge-to-surgery: 15% vs emergency surgery: 41%, p = 0.004). No differences were found regarding tumor recurrence, recurrence-free survival and overall survival. R1 resection (HR 47.2, 95%CI:4.1-543.7), number of lymph nodes harvested (HR 0.9 95%CI:0.8-0.99) and adjuvant therapy (HR 0.1 95%CI:0.01-0.9) predicted recurrence-free survival; pTMN stage IV (HR 7.3, 95%CI:1.1-47.6), number of lymph nodes harvested (HR 0.90, 95%CI:0.8-0.97), adjuvant therapy (HR 0.1, 95%CI:0.02-0.4) and surgery-related complications (HR 5.3, 95%CI:1.02-27.3) influenced overall survival. CONCLUSION Stent placement has a high success, similarly to emergency surgery, being associated with higher primary anastomosis and lower stoma rates. Tumor recurrence rate, recurrence-free survival and overall survival were comparable between groups; surgery-related complications influenced overall survival.

Abstract
As an alternative treatment to immediate surgical repair, endotracheal stent placement has been recently proposed in cases of iatrogenic tracheal damages. We report a case of a 91-year-old male who developed sudden subcutaneous emphysema during a total laryngectomy for laryngeal carcinoma. A tracheal tear at the distal third of the posterior tracheal wall was endoscopically assessed about 2 cm above the carina; CT confirmed the breach approximately 4 cm in length with associated pneumomediastinum and bilateral pneumothorax. Two covered self-expandable metal stents were then coaxially released under fluoroscopic control to cover the defect, restoring the tracheal integrity and leading to a normal thoracic appearance at CT and X-ray after 72 hours.

Abstract
AIM To investigate the efficacy and safety of endoscopic stent insertion in patients with delayed gastric emptying after gastrectomy.
METHODS In this study, we prospectively collected data from patients who underwent stent placement for delayed gastric emptying (DGE) after distal gastrectomy between June 2010 and April 2017, at a tertiary referral academic center. Clinical improvement, complications, and consequences after stent insertion were analyzed.
RESULTS Technical success was achieved in all patients (100%). Early symptom improvement was observed in 15 of 20 patients (75%) and clinical success was achieved in all patients. Mean follow-up period was 1178.3 ± 844.1 d and median stent maintenance period was 51 d (range 6-2114 d). During the follow-up period, inserted stents were passed spontaneously per rectum without any complications in 14 of 20 patients (70%). Symptom improvement was maintained after stent placement without the requirement of any additional intervention in 19 of 20 patients (95%).
CONCLUSION Endoscopic stent placement provides prompt relief of obstructive symptoms. Thus, it can be considered an effective and safe salvage technique for post-operative DGE.

Abstract
PURPOSE Wide-neck aneurysms (WNAs) associated with a dilated parent artery (PA) are not uncommon morphological abnormalities and usually cause inappropriate wall apposition and incomplete neck coverage of a tubular stent in stent-assisted coiling of aneurysms. We aimed to introduce a fusiform-shaped stent (FSS) and test its effectiveness in treating intracranial WNAs associated with a dilated PA using a three-dimensional (3D) model. MATERIALS AND METHODS Two FSS types were designed with the middle one-third segment dilated by 10% (FSS10) and 20% (FSS20) and were compared with the tubular-shaped stent (TSS). A patient-specific 3D WNA model was prototyped and produced, and in vitro stent placement was performed. Angiographic images of the three stent types were analyzed and compared using predetermined parameters. RESULTS The stent lumens were significantly larger in FSS10 and FSS20 than in TSS in the middle segments (P=0.046), particularly FSS20 (P=0.018). The non-covered area at the ostium tended to be smaller in FSS10 and FSS20 than in TSS, but the difference was not significant (P>0.05). The stent length was significantly longer in FSS10 and FSS20 than in TSS. The stent cell size was significantly larger in FSS than in TSS. CONCLUSION Better vessel wall apposition and aneurysmal neck coverage was observed for FSS than for TSS. No significant difference was observed between FSS10 and FSS20.

Abstract
BACKGROUND Both fully covered (FC) and partially covered (PC) self-expandable metal stents (SEMSs) are now commercially available for distal malignant biliary obstruction (MBO). While FCSEMS can be easily removed at the time of re-interventions, it is theoretically prone to migration. However, few comparative data between FC and PC SEMSs have been reported. AIMS The aim of this study was to compare clinical outcomes of FCSEMS with those of PCSEMS. METHODS This was a multicenter, prospective study of FCSEMS for unresectable distal MBO with a historical control of PCSEMS, which was previously reported as the WATCH study. The primary outcome was recurrent biliary obstruction (RBO), and secondary outcomes were stent migration, stent removal, stent-related adverse events, and survival. RESULTS A total of 151 cases with unresectable distal MBO undergoing FCSEMS placement were enrolled and compared with a historical cohort of 141 cases undergoing PCSEMS placement. No significant differences were found in the rate of RBO (29 vs. 33%; P = 0.451), time to RBO (318 vs. 373 days; P = 0.382), and survival (229 vs. 196 days; P = 0.177) between FCSEMS and PCSEMS. The rate of stent migration also did not differ significantly between the two groups (14 vs. 8%; P = 0.113). The removal of FCSEMSs was successful in all 24 attempted cases (100%). CONCLUSIONS FCSEMSs appeared comparable to PCSEMSs in terms of RBO without a significant increase in stent migration rate in patients with unresectable distal MBO.

Abstract
BACKGROUND Long-term studies evaluating self-expandable metal stents in patients who have unresectable malignant hilar biliary obstruction (UMHBO) after surgical reconstruction of the intestine remain inadequate. We developed a side-by-side (SBS) technique using a two-channel endoscope to place self-expandable metal stents in patients with UMHBO occurring after Billroth II reconstruction. AIMS We validated the long-term outcomes obtained with this technique. METHODS The study group comprised seven patients with UMHBO in whom we attempted to place metal stents by the SBS technique using a two-channel scope. The procedure was validated retrospectively. RESULTS The technical success rate was 86% and functional success rate was 100%. The median time to recurrent biliary obstruction (RBO) was 222 days (95% CI 4.9-439.1). Besides RBO, there were no other complications. CONCLUSIONS The SBS procedure performed using a two-channel scope is a safe and useful new technique for the treatment of UMHBO occurring after Billroth II reconstruction.

Abstract
PURPOSE Self-expandable metallic stents (SEMSs) may be used to effectively palliate malignant gastric outlet obstructions (GOOs), but their utility and efficacy in patients under best supportive care (BSC) have not been explored. METHOD In this multicenter retrospective study, we reviewed data on patients under BSC who underwent endoscopic SEMS placement to treat malignant GOO without chemotherapy. We evaluated the safety and efficacy of the procedure. RESULTS We enrolled a total of 208 patients. SEMS placement was technically successful in 207 (99.5%) and clinically successful in 164 (78.8%). The mean procedure time was 25.6 ± 2.8 min. Stent dysfunction later developed in 30 (14.4%) patients, of whom 90% (27/30) underwent reintervention. The procedure-related mortality rate was 1.44%; all deaths were due to pneumonia. Subgroup analysis by Karnofsky performance status (KPS) revealed that neither technical success, stent dysfunction, reintervention rate, procedure-related pneumonia or death, nor death within 14 days differed between patients with good and poor KPS. However, the clinical success rate and the median survival time were significantly lower and shorter, respectively, in those with poor KPS (p < 0.001). CONCLUSIONS Duodenal SEMS placement is an effective palliative treatment for malignant GOO in BSC patients. Although the GOO score did not dramatically improve in patients with poor KPS, the procedure was safe and palliatively feasible. Procedure-related pneumonia was fatal; thus, it is essential to proceed with great caution. TRIAL REGISTRATION Clinical trial registration number: UMIN000028367.

Abstract
AIM To evaluate the use of fully covered self-expandable metal stents (FCSEMSs) for pancreatic duct strictures in children with chronic pancreatitis.
METHODS Eight patients with refractory benign dominant stricture of the main pancreatic duct (MPD) were enrolled through chart reviews between December 2014 and June 2017 in a single center. Endoscopic retrograde cholangiopancreatography (ERCP) with placement of a 6-mm FCSEMS with dual flaps was performed. Endoscopic removal of FCSEMSs was performed with a snare or rat-tooth forceps. All procedures were performed by a pediatric gastroenterologist. For the assessment of outcomes, technical and clinical success, adverse events, and stent patency were evaluated retrospectively.
RESULTS The placement and removal of the FCSEMSs were successful in all 8 patients. Five patients were boys and 3 were girls. The median age at initial FCSEMS placement was 12 years (range, 5-18 years). The diameters of all the inserted stents were 6 mm, and the lengths were 4-7 cm. The median indwelling time was 6 mo (range, 3-10 mo). No pancreatic sepsis, pancreatitis, cholestasis, or mortality occurred. There was no proximal and distal migration. All subjects showed a patent stent. On follow-up ERCP, the mean diameter of the stricture improved from 1.1 mm to 2.8 mm (P < 0.05), whereas that of upstream dilation improved from 8.4 mm to 6.3 mm (P < 0.05).
CONCLUSION This initial experience showed that temporary FCSEMS placement is feasible and safe for the management of refractory benign MPD stricture in children.

Abstract
The prognosis of pancreatic cancer remains poor, even after initial surgical therapy. Local recurrence after Whipple’s pancreatico-duodenectomy may lead to intestinal obstruction at the level of the afferent limb or the alimentary limb. Endoscopic insertion of a self-expandable metal stent (SEMS) into the intestinal malignant stricture is the preferred method of choice for palliation. We describe two new endoscopic techniques to treat a malignant intestinal obstruction with the insertion of a SEMS into the afferent limb and the alimentary limb. A case of malignant gastric outlet obstruction after a Whipple’s resection was treated by the creation of an endoscopic gastrojejunostomy by the insertion of a lumen apposing HotAxios stent in between the stomach and the alimentary limb under fluoroscopic and endoscopic ultrasound control. Biliary obstruction and jaundice caused by a malignant stricture of the afferent limb after a Roux-en-Y Whipple’s resection was treated by the insertion of a SEMS by means of the single-balloon overtube-assisted technique under fluoroscopic control. Feasibility and advantages of both techniques are discussed.

Abstract
AIM To evaluate the safety and efficacy of limited endoscopic sphincterotomy (ES) before placement of self-expandable metal stent (SEMS).
METHODS This was a retrospective analysis of 244 consecutive patients with unresectable malignant biliary obstruction, who underwent placement of SEMSs following limited ES from December 2008 to February 2015. The diagnosis of malignant biliary obstruction and assessment of patient eligibility for the study was established by a combination of clinical findings, laboratory investigations, imaging and pathological results. All patients were monitored in the hospital for at least 24 h following endoscopic retrograde cholangio pancreatography (ERCP). The incidence of immediate or early post-ERCP complications such as post-ERCP pancreatitis (PEP) and bleeding related to limited ES were considered as primary outcomes. Also, characteristics and complications according to the cancer type were classified.
RESULTS Among the 244 patients included, the underlying diagnosis was cholangiocarcinoma in 118 patients, pancreatic cancer in 79, and non-pancreatic or non-biliary malignancies in the remaining 47 patients. Early post-ERCP complications occurred in 9 patients (3.7%), with PEP in 7 patients (2.9%; mild, 6; moderate, 1) and mild bleeding in 2 patients (0.8%). There was no significant association between the incidence of post-ERCP complications and the type of malignancy (cholangiocarcinoma vs pancreatic cancer vs others, P = 0.696) or the type of SEMS used (uncovered vs covered, P = 1.000). Patients who had more than one SEMS placed at the first instance were at a significantly higher risk of post-ERCP complications (one SEMS vs two SEMS, P = 0.031). No other factors were predictive of post-ERCP complications.
CONCLUSION Limited ES is feasible and safe, and effectively facilitates the placement of SEMS, without any significant risk of PEP or severe bleeding.

Abstract
AIM: To assess anti-migration potential of six biliary covered self-expandable metal stents (C-SEMSs) by using a newly designed phantom model.
METHODS: In the phantom model, the stent was placed in differently sized holes in a silicone wall and retracted with a retraction robot. Resistance force to migration (RFM) was measured by a force gauge on the stent end. Radial force (RF) was measured with a RF measurement machine. Measured flare structure variables were the outer diameter, height, and taper angle of the flare (ODF, HF, and TAF, respectively). Correlations between RFM and RF or flare variables were analyzed using a linear correlated model.
RESULTS: Out of the six stents, five stents were braided, the other was laser-cut. The RF and RFM of each stent were expressed as the average of five replicate measurements. For all six stents, RFM and RF decreased as the hole diameter increased. For all six stents, RFM and RF correlated strongly when the stent had not fully expanded. This correlation was not observed in the five braided stents excluding the laser cut stent. For all six stents, there was a strong correlation between RFM and TAF when the stent fully expanded. For the five braided stents, RFM after full stent expansion correlated strongly with all three stent flare structure variables (ODF, HF, and TAF). The laser-cut C-SEMS had higher RFMs than the braided C-SEMSs regardless of expansion state.
CONCLUSION: RF was an important anti-migration property when the C-SEMS did not fully expand. Once fully expanded, stent flare structure variables plays an important role in anti-migration.

Abstract
INTRODUCTION Anastomotic or staple-line leak after foregut surgery presents a formidable management challenge. In recent years, with advancement of endoscopy, self-expanding covered stents have been gaining popularity. In this study, we aimed to determine the safety and effectiveness of self-expanding covered stents in management of leak after foregut surgery. METHODS Consecutive patients who received a fully covered self-expandable metal stent (SEMS) due to an anastomotic leak after upper gastrointestinal surgery between 2009 and 2014 were retrospectively reviewed. Demographic data, stent placement and removal, clinical success, time to resolution, and complications were collected. Predictive factors for clinical success rate were assessed. RESULTS A total of 20 consecutive patients underwent placement of fully covered SEMS for anastomotic leak, following esophagectomy (n = 5), esophageal diverticulectomy (n = 1), gastric sleeve (n = 4), gastric bypass (n = 3), partial gastrectomy (n = 4), and total gastrectomy (n = 3). All the stents were removed successfully, and clinical resolution was achieved in 18 patients (90 %) after a median of two (range 1-3) procedures and a mean of 6.2 weeks (range 0.4-14). Complications presented in 12 patients (60 %), including stent migration (n = 8), mucosal friability (n = 4), tissue integration (n = 2), and bleeding (n = 2). Two (10 %) patients' treatment was complicated by aorto-esophageal fistula formation resulting in one death. Demographic factors, comorbidities, and type of surgery were not predictive of clinical success rate or time to resolution. CONCLUSION SEMS are effective tools for the management of leaks after foregut surgery. The biggest challenge with this approach is stent migration. Caution is warranted due to the risk of fatal complications such as aorto-esophageal fistula formation. No type of surgery or particular patient factor, including age, sex, BMI, albumin, history of radiation, malignancy, and comorbid diabetes or coronary artery disease, appeared to be correlated with success rate. Larger studies are needed to determine factors predictive of clinical success.

Abstract
BACKGROUD The efficacy and safety of self-expandable metallic stents (SEMSs) as a bridge for patients with acute malignant colorectal obstructions (AMCOs) are still controversial. We conducted this study to evaluate the outcomes of patients with AMCOs treated by different strategies. METHODS From January 2010 to March 2014, a total of 171 patients with AMCOs from Zhongshan Hospital were retrospectively enrolled in this study. One hundred twenty patients successfully received stent placement followed by one-stage laparoscopic or open resection in the stent group, and 51 patients received emergency operations in the emergency group. RESULTS The operation duration and postoperative hospital stay were significantly shorter in the stent group (114.51 ± 28.65 vs. 160.39 ± 58.94 min, P < 0.001; 8.00 ± 3.97 vs. 12.59 ± 9.07 days, P = 0.001). The stent group also had significantly reduced intraoperative blood loss and the incidence of postoperative complications compared with the emergency group (61.00 ± 43.70 vs. 121.18 ± 85.90 ml, P < 0.001; 16.7 vs. 37.3%, P = 0.003). Kaplan-Meier survival curves showed that the median survival time in the stent group was significantly longer than that in the emergency group (53 vs. 41 months, P = 0.034). In subgroup analysis of stent group, the stent laparoscopy group had significantly decreased postoperative complications (P = 0.025), and similar long-term survival (P = 0.81). CONCLUSIONS Stent placement as a bridge to surgery is a safe and feasible procedure and provides significant advantages in terms of short-term outcomes and favorable prognoses for patients with AMCOs. Laparoscopic surgery could be considered as an optimal treatment after stent placement.

Abstract
BACKGROUND In patients with unresectable colorectal cancer (CRC) obstruction, choosing whether to perform self-expandable metal stent (SEMS) or palliative surgery is challenging, especially in those with good performance status. We aimed to compare the long-term outcomes of SEMS with those of palliative surgery in patients with unresectable CRC obstruction. METHODS This retrospective study comprised 114 patients with unresectable CRC obstruction who underwent SEMS placement (n = 73) or palliative surgery (n = 41). The main outcome measurements were success rate, adverse events, patency, and survival duration. RESULTS Early clinical success rates did not differ between SEMS and surgery. However, the rate of late adverse events was significantly higher in the SEMS group (27.4 vs. 9.8 %; P = .005). Patency duration was shorter after SEMS than after surgery (163 vs. 349 days; P < .001), even after additional intervention (202 vs. 349 days; P < .001). The median survival was significantly shorter after SEMS than after surgery (209 vs. 349 days; P = .005). Survival differed between treatments in patients with Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 (P = .016) but not in those with ECOG 2 or 3 (P = .487), and this was confirmed by multivariate analysis, which showed that surgery was a significant favorable predictor of survival for patients with ECOG 0 or 1 (hazard ratio .442; 95 % confidence interval .234-.835; P = .016). CONCLUSIONS Surgery may be preferable to SEMS for the palliation of unresectable CRC obstruction in patients with good performance status, especially ECOG 0 or 1.

Abstract
Stents are tubular devices made of plastic or metal. Endoscopic stenting is the most common treatment for obstruction of the common bile duct or of the main pancreatic duct, but also employed for the treatment of bilio-pancreatic leakages, for preventing post- endoscopic retrograde cholangiopancreatography pancreatitis and to drain the gallbladder and pancreatic fluid collections. Recent progresses in techniques of stent insertion and metal stent design are represented by new, fully-covered lumen apposing metal stents. These stents are specifically designed for transmural drainage, with a saddle-shape design and bilateral flanges, to provide lumen-to-lumen anchoring, reducing the risk of migration and leakage. This review is an update of the technique of stent insertion and metal stent deployment, of the most recent data available on stent types and characteristics and the new applications for biliopancreatic stents.

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

Abstract
Endoscopic stenting has become a widely method for the management of various malignant and benign pancreatico-biliary disorders. Biliary and pancreatic stents are devices made of plastic or metal used primarily to establish patency of an obstructed bile or pancreatic duct and may also be used to treat biliary or pancreatic leaks, pancreatic fluid collections and to prevent post-endoscopic retrograde cholangiopancreatography pancreatitis. In this review, relevant literature search and expert opinions have been used to evaluate the outcome of stenting in biliary and pancreatic benign and malignant diseases.

Abstract
Endoscopic management of unresectable hilar malignant biliary stricture (MBS) is currently challenging, and the best approach is still controversial. Liver volume is the key to adequate biliary drainage in hilar MBS and multiple stenting is mandatory to drain over 50% of liver volume in most cases. The self-expandable metallic stent (SEMS) has shown superior patency to plastic stents in recent reports. There are two methods of multiple stenting for hilar MBS: stent-in-stent (SIS) and side-by-side (SBS). Advantages of SIS include multiple SEMS placement in one stent caliber at the common bile duct (CBD), which is considered physiologically ideal. The through-the-mesh (TTM) technique with guidewires and the SEMS delivery system can be technically difficult in SIS, although the recent development of dedicated SEMSs having a loose portion facilitating the TTM technique makes SIS technically feasible both at stent deployment and re-interventions. Conversely, the SBS technique, if placed across the papilla, is technically simple at initial placement and re-intervention at stent occlusion. However, SBS has potential disadvantages of overexpansion of the CBD because of parallel placement of multiple SEMS, which can lead to portal vein thrombosis. Given the limited evidence available, a well-designed randomized controlled trial comparing these two techniques is warranted.

Abstract
AIM: To review results of endoscopic treatment for anastomotic biliary strictures after orthotopic liver transplantation (OLT) during an 8-year period.
METHODS: This is a retrospective review of all endoscopic retrograde cholangiopancreatographys (ERCPs) performed between May 2006 and June 2014 in deceased OLT recipients with anastomotic stricture at a tertiary care hospital. Patients were divided into 2 groups, according to the type of stent used (multiple plastic or covered self-expandable metal stents), which was chose on a case-by-case basis and their characteristics. The primary outcome was anastomotic stricture resolution rate determined if there was no more than a minimum waist at cholangiography and a 10 mm balloon could easily pass through the anastomosis with no need for further intervention after final stent removal. Secondary outcomes were technical success rate, number or ERCPs required per patient, number of stents placed, stent indwelling, stricture recurrence rate and therapy for recurrent anastomotic biliary stricture (AS). Stricture recurrence was defined as clinical laboratorial and/or imaging evidence of obstruction at the anastomosis level, after it was considered completely treated, requiring subsequent interventional procedure.
RESULTS: A total of 195 post-OLT patients were assessed for eligibility. One hundred and sixty-four (164) patients were diagnosed with anastomotic biliary stricture. ERCP was successfully performed in 157/164 (95.7%) patients with AS, that were treated with either multiple plastic (n = 109) or metallic billiary stents (n = 48). Mean treatment duration, number of procedures and stents required were lower in the metal stent group. Acute pancreatitis was the most common procedure related complication, occurring in 17.1% in the covered self-expandable metal stents (cSEMS) and 4.1% in the multiple plastic stent (MPS) group. Migration was the most frequent stent related complication, observed in 4.3% and 5.5% (cSEMS and MPS respectively). Stricture resolution was achieved in 86.8% in the cSEMS group and in 91% in MPS group. Stricture recurrence after a median follow up of 20 mo was observed in 10 (30.3%) patients in the cSEMS and 7 (7.7%) in the plastic stent group, a statistically significant difference (P = 0.0017). Successful stricture resolution after secondary treatment was achieved in 66.6% and 62.5% of patients respectively in the cSEMS and plastic stents groups.
CONCLUSION: Multiple plastic stents are currently the first treatment option for AS in patients with duct-to-duct anastomosis. cSEMS was associated with increased pancreatitis risk and higher recurrence rate.
