Abstract Background EUS guided gallbladder drainage has gradually emerging as an option among patients with cholecystitis. Stent bridged endoscope intervention in the gallbladder was further introduced. The aim of this study was to assess the effectiveness and safety of the ECE-LAMS and this newly designed retrievable puncture anchor applied in the transmural Cholecystolithotomy. Method We retrospectively reviewed consecutive patients undergoing EUS-guided transmural cholecystoscopic therapy. The main outcome measures for the EUS-GBD procedure were techniques success and adverse events, which were also compared between guided assisted group and retrievable anchor assisted group. The main outcome measures for the transmural cholecystoscopy after EUS-GBD were the stent indwelling time, clinical success and adverse events. Results A total of 24 (15 female) patients with gallstones were received the transluminal Cholecystolithotomy. Mean age is 36.08±13.69 years old. The successful rate of the anchor assisted group was high than the guidewire assisted group (92.9% Vs 70%, P=0.07). On the average of 12.25±2.77 (range 8-17) days after the initial BD drainage procedure, 20 patients received the per-oral cholecystoscopy via the fistula. Fistula broken was found in 2 patients in which the per-oral cholecystoscopy was applied on the ninth day after the EUS-GBD. During the follow-up period (mean 314.2± 213.7 days) no GB stones recurrence or other long term complications reported. Conclusion In conclusion, we have demonstrated that EUS-assisted per-oral cholecystoscopy technique with ECE-LMAS is an efficient and safe procedure. For the EUS-GBD procedure, retrievable anchor could significantly increase the success rate compared with the guidewire.

Abstract Background Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is gradually emerging as an option among patients with cholecystitis. A stent-bridged endoscopic intervention in the gallbladder (GB) was further introduced. The aim of this study was to assess the effectiveness and safety of the electrocautery-enhanced delivery of a lumen apposing metal stent (ECE-LAMS) and this newly designed retrievable anchor (RA) applied in the transmural cholecystolithotomy. Method We retrospectively reviewed consecutive patients undergoing EUS-guided transmural cholecystoscopic therapy. The main outcome measures for the EUS-GBD procedure were technical success and adverse events, which were also compared between the guided assisted group and the RA-assisted group. The main outcome measures for transmural cholecystoscopy after EUS-GBD were the stent indwelling time, clinical success, and adverse events. Results A total of 24 (15 female) patients with gallstones received transluminal cholecystolithotomy. The mean age of the patients was 36.08±13.69 years. The success rate of the anchor-assisted group was higher than that of the guidewire-assisted group (92.9% vs. 70%, P=0.07). On an average of 12.25±2.77 (range 8-17) days after the initial GB drainage procedure, 20 patients received per-oral cholecystoscopy via the fistula. A ruptured fistula was found in 2 patients in whom the per-oral cholecystoscopy was applied on the ninth day after EUS-GBD. During the follow-up period (mean 314.2± 213.7 days), no GB stone recurrence or other long-term complications were reported. Conclusion We demonstrated that the EUS-assisted per-oral cholecystoscopy technique with ECE-LMAS is an efficient and safe procedure. For the EUS-GBD procedure, a RA could significantly increase the success rate compared with the guidewire.

Abstract Background Repeat per-oral endoscopic myotomy is occasionally performed for persistent/recurrent symptoms in patients with achalasia, and yields favorable outcomes. We investigated a novel technique, per-oral endoscopic dual myotomy (dual-POEM), where a second myotomy was performed during a single session to augment the efficacy and avoid repeat interventions. The aim of this study was to evaluate its feasibility, safety and efficacy. Methods Consecutive patients diagnosed with achalasia who underwent dual-POEM (1/2018–5/2019) were prospectively collected and retrospectively analyzed. Patients with baseline Eckardt score ≥ 9, ≥ 10 years of symptoms, and/or having prior interventions other than myotomy received dual-POEM. The primary outcome was clinical success (Eckardt score ≤ 3). Secondary outcomes were procedure-related adverse events, change in lower esophageal sphincter (LES) pressure, and reflux complications. Results Seventeen patients received dual-POEM. Procedure-related adverse events were observed in 2 (11.8%) patients (mucosal injury and pneumonitis). Both were minor in severity. During a median follow-up of 33 months (interquartile range, IQR [31,35]; range, 19–36), clinical success was achieved in 16 (94.1%) patients. The median Eckardt score decreased from 9 (IQR [8, 11.5]; range 7–12) to 1 (IQR [1, 2]; range 0–4) (P < 0.001), and LES pressure decreased from 25.8 mmHg (IQR [21.7, 33.5]; range 17.7–46.3) to 7.4 mmHg (IQR [6.3, 10.4]; range 2.2–12.6) (P < 0.001). Seven (41.2%) patients developed postprocedural reflux either by gastroesophageal reflux disease questionnaire or esophagitis endoscopically, all successfully treated with proton pump inhibitors. Conclusion Dual-POEM preliminarily demonstrated high efficacy with a favorable safety profile in patients with achalasia with predictors of treatment failure.

Abstract Background: Data on the long-term outcomes of gastric peroral endoscopic myotomy (G-POEM) for refractory gastroparesis are lacking. We report the results of a large multicenter long-term follow-up study of G-POEM for refractory gastroparesis. Methods: This was a retrospective multicenter study of all G-POEM operations performed in seven expert French centers for refractory gastroparesis with at least 1 year of follow-up. The primary endpoint was the 1-year clinical success rate, defined as at least a 1-point improvement in the Gastroparesis Cardinal Symptom Index (GCSI). Results: 76 patients were included (60.5 % women; age 56 years). The median symptom duration was 48 months. The median gastric retention at 4 hours (H4) before G-POEM was 45 % (interquartile range [IQR] 29 % – 67 %). The median GCSI before G-POEM was 3.6 (IQR 2.8 – 4.0). Clinical success was achieved in 65.8 % of the patients at 1 year, with a median rate of reduction in the GCSI score of 41 %. In logistic regression analysis, only a high preoperative GCSI satiety subscale score was predictive of clinical success (odds ratio [OR] 3.41, 95 % confidence interval [CI] 1.01 – 11.54; P = 0.048), while a high rate of gastric retention at H4 was significantly associated with clinical failure (OR 0.97, 95 %CI 0.95 – 1.00; P = 0.03). Conclusions: The results confirm the efficacy of G-POEM for the treatment of refractory gastroparesis, as evidenced by a 65.8 % clinical success rate at 1 year. Although G-POEM is promising, prospective sham-controlled trials are urgently needed to confirm its efficacy and identify the patient populations who will benefit most from this procedure.

Abstract Background Bile duct injury (BDI) remains a daunting complication of laparoscopic cholecystectomy. In patients with complex BDI, a percutaneous-endoscopic rendezvous procedure may be required to establish bile duct continuity. The aim of this study was to assess short- and long-term outcomes of the rendezvous procedure. Methods All consecutive patients with BDI referred to our tertiary referral center between 1995 and 2016 were analyzed. A rendezvous procedure was performed when endoscopic or radiologic intervention failed, and when deemed feasible by a dedicated multidisciplinary team including hepatopancreaticobiliary surgeons, gastrointestinal endoscopists, and interventional radiologists. Classification of BDI, technical success of the rendezvous procedure, procedure-related adverse events, and outcomes were assessed. Results Among a total of 812 patients, rendezvous was performed in 47 (6 %), 31 (66 %) of whom were diagnosed with complete transection of the bile duct (Amsterdam type D/Strasberg type E injury). The primary success rate of rendezvous was 94 % (44 /47 patients). Overall morbidity was 18 % (10 /55 procedures). No life-threatening adverse events or 90-day mortality occurred. After a median follow-up of 40 months (interquartile range 23 – 54 months), rendezvous was the final successful treatment in 26 /47 patients (55 %). In 14 /47 patients (30 %), rendezvous acted as a bridge to surgery, with hepaticojejunostomy being chosen either primarily or secondarily to treat refractory or relapsing stenosis. Conclusions In experienced hands, rendezvous was a safe procedure, with a long-term success rate of 55 %. When endoscopic or transhepatic interventions fail to restore bile duct continuity in patients with BDI, rendezvous should be considered, either as definitive treatment or as a bridge to elective surgery.

Abstract Background and study aims Per-oral endoscopic myotomy (POEM) is associated with a short-term clinical response of 82 % to 100 % in treatment of patients with achalasia. Data are limited on the long-term durability of the clinical response in these patients. The aim of this study was to determine the long-term outcomes of patients undergoing POEM for management of achalasia. Methods This was a retrospective multicenter cohort study of consecutive patients who underwent POEM for management of achalasia. Patients had a minimum of 4 years follow-up. Clinical response was defined by an Eckardt score ≤ 3. Results A total of 146 patients were included from 11 academic medical centers. Mean (± SD) age was 49.8 (± 16) years and 79 (54 %) were female. The most common type of achalasia was type II, seen in 70 (47.9 %) patients, followed by type I seen in 41 (28.1 %) patients. Prior treatments included: pneumatic dilation in 29 (19.9 %), botulinum toxin injection in 13 (8.9 %) and Heller myotomy in seven patients (4.8 %). Eight adverse events occurred (6 mucosotomies, 2 pneumothorax) in eight patients (5.5 %). Median follow-up duration was 55 months (IQR 49.9–60.6). Clinical response was observed in 139 (95.2 %) patients at follow-up of ≥ 48 months. Symptomatic reflux after POEM was seen in 45 (32.1 %) patients, while 35.3 % of patients were using daily PPI at 48 months post POEM. Reflux esophagitis was noted in 16.8 % of patients who underwent endoscopy. Conclusion POEM is a durable and safe procedure with an acceptably low adverse event rate and an excellent long-term clinical response.

Abstract Background Elbow arthroscopy is becoming increasingly important for the treatment of a wide range of acute and chronic elbow pathologies. Even if elbow arthroscopy is technically demanding, in the pediatric population this minimally invasive technique is preferred by many surgeons for the treatment of pathologies such as osteochondritis dissecans (OCD), posttraumatic stiffness (PTS), or elbow posterior impingement (PI). The aim of this study is to evaluate outcomes and safety of elbow arthroscopy in the pediatric and adolescent population after long-term follow-up. Materials and methods In this retrospective study, 26 patients younger than 18 years old undergoing elbow arthroscopy were evaluated. All surgeries were performed by a single senior surgeon. Patients were divided into three subgroups based on preoperative diagnosis: OCD, PTS, and PI. After at least 60 months follow-up, several outcome measures, including range of motion (ROM), Mayo Elbow Performance Score (MEPS), and visual analog scale (VAS) were evaluated in relation to preoperative values. The level of patient satisfaction on a five-level Likert scale, any limitation or change in sport activity, and the onset of any possible complications were also evaluated. Results In the study population, we found an improvement in ROM (flexion of 14.4 ± 13.6°, extension of 19.5 ± 13.9°, pronation of 5.8 ± 5.7°, and supination of 8.5 ± 11.6°) and in validated outcome measures (MEPS of 21.0 ± 13.5 points and VAS of 3.8 ± 2.2 points). The satisfaction rate was 4.5, with no dissatisfaction. Eighty-seven percent of patients fully recovered their performance levels, 9% changed sport, and 4% were unable to return to sport. We identified one major and one minor complication, with an overall complication rate of 7.7%. No neurovascular injuries were detected. Conclusions Elbow arthroscopy in a pediatric population can be considered an effective and safe procedure for selected pathologies when performed by an experienced surgeon. At long-term follow-up, we reported excellent clinical outcomes (both objective and subjective), with a relatively low complication rate without permanent injuries. Level of evidence Level IV—case series.

Abstract Background and study aims The aim of this study was to assess long-term clinical outcomes beyond 6 years in patients who underwent per-oral endoscopic myotomy (POEM) for the treatment of achalasia. Patients and methods Patients with achalasia who underwent POEM between 2010 and 2012 and had follow-up of at least 6 years were retrospectively identified at eight tertiary care centers. The primary outcome evaluated was clinical success defined by an Eckardt symptom score (ESS) ≤ 3 for the duration of the follow-up period. The clinical success cohort was compared to failure (ESS > 3 at any time during follow-up) in order to identify characteristics associated with symptom relapse. The incidence of patient-reported gastroesophageal reflux (GER) was also evaluated. Results Seventy-three patients with 6-year follow-up data were identified. Sustained clinical remission was noted in 89 % (65/73) at 6-years. Mean ESS decreased from 7.1 ± 2.3 pre-procedure to 1.1 ± 1.1 at 6 years (P < 0.001). Symptomatic reflux was reported by 27 of 72 patients (37.5 %). Type I achalasia (OR 10.8, P = 0.04) was found to be associated with clinical failure on logistic regression analysis. Conclusions In patients with achalasia, POEM provides high initial clinical success with excellent long-term outcomes. There are high rates of patient-reported gastroesophageal reflux post-procedure which persist at long-term follow-up.

Abstract Background and study aims The rate of gastroesophageal reflux disease (GERD) after per oral endoscopic myotomy (POEM) is concerning. Endoscopic anti-reflux methods, such as Trans Oral Incisionless Fundoplication (TIF), are crucial for the long-term success of POEM, especially if they can be performed in the same session. Methods We completed a proof-of-concept canine pilot study (n = 6) to assess safety and feasibility of POEM and TIF in a single session (POEM-TIF). Subsequently, POEM-TIF was also performed in patients with achalasia (n = 5). Herein, we report on the safety, technical and clinical success of the first-in-human cases with symptom follow-up at 1, 3 and 6 months and pH testing at 6 months. Results POEM was completed successfully in six canines (3 anterior and 3 posterior myotomies), followed by TIF in the same session. Necropsy and extensive testing demonstrated no evidence of mucosal injury and no leaks. The reconstructed valve was 220 to 240 degrees, 3 to 4 cm in length, and resulted in concomitant esophageal lengthening (2–5 cm). Using similar principles, the first-in-human cases were performed without intraprocedural or delayed adverse events. pH testing at 6 months showed that four of five patients had no evidence of GERD (DeMeester > 14.72), and in one case, there was evidence of esophagitis. Conclusions Single session POEM-TIF appears to be safe and feasible. Early clinical human data suggests that it may be able to reduce post POEM GERD, however the additional secondary benefits such as lengthening and straightening of the esophagus, may prove to be equally important for the long-term success of POEM.

Few studies have reported on simultaneous endovascular stenting for tandem posterior circulation (PC) stenoses and its long-term outcomes. Thus, our aim was to investigate the safety and efficacy of simultaneous stenting in patients with symptomatic tandem extra- and intracranial PC stenoses. From September 2014 to June 2018, 16 such patients with symptomatic stenoses who underwent simultaneous stent placement were analyzed. The primary outcome was occurrence of any stroke, TIA, or death within 30 days after the procedure. The secondary outcomes were technical success, clinical success, and the occurrence of in-stent restenosis ≥50% during follow-up. Technical success was defined as stent coverage of all tandem lesions and residual stenosis &lt;30%. Clinical success was determined based on any occurrence of neurological events or death within 3 months after the procedure. All stents (19 intracranial and 14 extracranial) were placed with a technical success rate of 100%. One patient experienced a pontine ischemic stroke 2 days after the procedure and had recovered well at discharge. One patient experienced a minor complication of groin hematoma. The clinical success rate was 93.75% (15/16). During a median follow-up of 36.0 ± 11.0 months, two patients developed ISR ≥50% at the 1-year follow-up. None of the patients experienced stroke, TIA, or death after discharge during follow-up. Simultaneous stenting for symptomatic tandem extra- and intracranial PC stenoses is safe and feasible. Its impact on long-term stroke prevention is promising, and further study of a larger patient population is needed.

OBJECT Endoscopic third ventriculostomy (ETV) is the procedure of choice in the treatment of obstructive hydrocephalus. The excellent clinical and radiological success rates are well known. Nevertheless, very few papers have addressed the very long term outcomes of the procedure in very large series. The authors present a large case series of 113 patients who underwent 126 ETVs, and they highlight the initial postoperative outcome after 3 months and long-term follow-up with an average of 7 years. METHODS All patients who underwent ETV at the Department of Neurosurgery, Mainz University Hospital, between 1993 and 1999 were evaluated. Obstructive hydrocephalus was the causative pathology in all cases. RESULTS The initial clinical success rate was 82% and decreased slightly to 78% during long-term follow-up. Long-term success was analyzed using Kaplan-Meier curves. Overall, ETV failed in 31 patients. These patients underwent a second ETV or shunt treatment. A positive impact on long-term success was seen for age older than 6 months, and for obstruction due to cysts or benign aqueductal stenosis. The complication rate was 9% with 5 intraoperative and 5 postoperative events. CONCLUSIONS The high clinical success rate in short-term and long-term follow-up confirms ETV’s status as the gold standard for the treatment of obstructive hydrocephalus, especially for distinct pathologies. The patient’s age and underlying pathology may influence the outcome. These factors should be considered carefully preoperatively by the surgeon.
