Endoscopic ultrasound (EUS)-guided interventions have revolutionized the management of malignant biliary obstruction (MBO) and gastric outlet obstruction (GOO), providing minimally invasive alternatives with improved outcomes. These procedures have significantly reduced the need for high-risk surgical interventions or percutaneous alternatives and have provided effective palliative care for patients with advanced gastrointestinal and bilio-pancreatic malignancies. EUS-guided biliary drainage (EUS-BD) techniques, including hepaticogastrostomy (EUS-HGS), choledochoduodenostomy (EUS-CDS), and antegrade stenting (EUS-AS), offer high technical and clinical success rates, with a good safety profile particularly when Endoscopic Retrograde Cholangiopancreatography (ERCP) is not feasible. EUS-HGS, which allows biliary drainage by trans-gastric route, is primarily used for proximal stenosis or in case of surgically altered anatomy; EUS-CDS with Lumen-Apposing Metal Stent (LAMS) for distal MBO (dMBO), EUS-AS as an alternative of EUS-HGS in the bridge-to-surgery scenario or when retrograde access is not possible and EUS-guided gallbladder drainage (EUS-GBD) with LAMS in case of dMBO with cystic duct patent without dilation of common bile duct (CDB). EUS-guided gastroenterostomy (EUS-GE) has already established its role as an effective alternative to surgical GE and enteral self-expandable metal stent, providing relief from GOO with fewer complications and faster recovery times. However, we do not yet have strong evidence on how to combine the different EUS-guided drainage techniques with EUS-GE in the setting of double obstruction. This comprehensive review aims to synthesize growing evidence on this topic by randomized controlled trials, cohort studies, and case series not only to summarize the efficacy, safety, and technical aspects of these procedures but also to propose a treatment algorithm based essentially on the anatomy and stage of the neoplasm to guide clinical decision-making, incorporating the principles of personalized medicine. This review also highlights the transformative impact of EUS-guided interventions on the treatment landscape for MBO and GOO. These techniques offer safer and more effective options than traditional approaches, with the potential for widespread clinical adoption. Further research is needed to refine these procedures, expand their applications, and improve patient care and quality of life. [ABSTRACT FROM AUTHOR]

Background: A bezoar is defined as a foreign body resulting from the accumulation of ingested material or food in the stomach. However, they can also be found in the duodenum and other segments of the intestine. The average age of occurrence is 11 years, predominantly affecting females. Among its complications, gastric outlet obstruction is the most frequent, though secondary gastric perforation is extremely rare. Material and Methods: Four clinical cases are presented from a third‐level care facility in Mexico City over the period 2022–2024, all resolved surgically. Results: Four clinical cases involved females aged between 11 and 14 years. All cases presented with generalized abdominal pain, an epigastric mass, nausea, and vomiting. In one case, a gastric perforation occurred. Postsurgical complications included superficial surgical site infections in two cases, an average of 5 days of nil per oral (NPO), and an average hospital stay of 9.2 days. All patients were referred to the pediatric psychiatry service for follow‐up after discharge. Conclusion: Trichobezoar is a rare pathology with a marked incidence in our population, having multiple cases within such a short period. This situation provides a new path to establish an epidemiological basis in our Mexican population and to explore the link between these clinical cases, offering insights into their causes, symptoms, and treatment options.

Purpose of review: Gastric outlet obstruction is a syndrome that is caused by several benign and malignant diseases. Endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) is a novel treatment that seems to combine the advantages of the two traditional treatments: enteral stent placement (ES) and surgical gastrojejunostomy (SGJ). This review aims to determine the current position of EUS-GE amidst the two traditional treatment options. Recent findings: Different approaches can be adopted to facilitate EUS-GE. Direct gastroenterostomy seems to have the shortest procedure time. All methods possess high technical success rates. Several retrospective analyses have compared EUS-GE to ES and SGJ. EUS-GE seems to have better stent patency compared to ES and a lower adverse event rate compared to SGJ. Recently, randomized trials have been initiated which compare EUS-GE with ES or SGJ. Summary: Although the currently published literature unequivocally shows the great promises of EUS-GE, properly powered and controlled studies are warranted to ascertain the definitive position of EUS-GE within the treatment repertoire of GOO. Until reliable data has been collected, EUS-GE can be considered a safe and effective alternative to ES and SGJ. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 16-year-old girl who was admitted with worsening abdominal pain, nausea, and vomiting. It details her medical history, including iron-deficiency anemia, anxiety disorder, and pica, as well as her symptoms over a four-week period. It is reported that despite multiple visits to the emergency department and initial treatments, her condition persisted, leading to further investigations.

The authors presented a case of duodenal obstruction in a 61-year-old man, resulting from an annular pancreas diagnosed on imaging (computed tomography, magnetic resonance cholangiopancreatography, and endoscopic ultrasound). The patient underwent a diagnostic laparoscopy. Intraoperatively, given a straightforward appearance and anatomy of the annular pancreas overlying the second part of the duodenum, and due to extensive adhesions in the abdomen, a primary division of the annular pancreas was performed, instead of a bypass procedure such as gastrojejunostomy. He had some residual symptoms 1 week postoperatively which was treated with duodenal dilatation endoscopically. On review and follow-up at 1 year, he has remained well with resolution of symptoms, supported by radiological improvement on a computed tomography performed at 4 months post-operatively. We believe this approach has resulted in less morbidity and a shorter period of recovery as compared to a bypass procedure and represents a reasonable therapeutic option for annular pancreas.

Background: Malignant Distal Biliary Obstruction (MBDO) is a common event occurring along the natural history of both pancreatic cancer and cholangiocarcinoma. Epidemiological and biological features make MBDO one of the key elements of the clinical management of patients suffering for of pancreatic cancer or cholangiocarcinoma. The development of dedicated biliary lumen-apposing metal stents (LAMS) is changing the clinical work up of patients with MBDO. i-EUS is an Italian network of clinicians and scientists with a special interest in biliopancreatic endoscopy, EUS in particular. Methods: The scientific methodology was chosen in line with international guidance and in a fashion similar to those applied by broader scientific associations. PICO questions were elaborated and subsequently voted by a broad panel of experts within a simplified Delphi process. Results and conclusions: The manuscripts describes the results of a consensus conference organized by i-EUS with the aim of providing an evidence based-guidance for the appropriate use of the techniques in patients with MBDO.

Background: Effective hospital discharge planning is crucial, particularly in educating caregivers on handling medical devices. This education helps manage the patient's signs and symptoms, prevents post-discharge complications, and reduces early readmissions. This study aimed to understand aspects involved in the acquisition of mastery by home caregivers, in handling care of a patient who just underwent gastrostomy, after educational intervention during hospitalization and telemonitoring upon return home. Methods: Qualitative descriptive study. It followed 15 caregivers of people with percutaneous endoscopic gastrostomy. The intervention took place between November 2022 and July 2023 in the neuromusculoskeletal unit of a Brazilian university hospital. Results: The educational intervention had four stages. In stage 1, caregivers felt confused and uncertain about managing PEG. By stage 2, they expressed a desire to be capable of handling care, especially in the event of potential complications, and showed increased awareness and engagement. Stage 3 highlighted the effectiveness of hands-on training with feedback from professionals. In stage 4, during monitoring, several complications were noted, including granuloma formation in the stoma, tube obstruction, and accidental tube loss. However, caregivers demonstrated the ability to handle these situations, indicating the effectiveness of the training and telemonitoring interventions. Conclusions: Nursing professionals should consider various factors when training caregivers in a hospital setting, including providing adequate space, allocating sufficient time for educational interventions, offering both theoretical and practical demonstrations, ensuring effective communication, and taking into account the caregivers' context, as they play a direct role in acquiring a safe and effective skill set.

A 79-year-old female presented with a 3-week history of dysphagia and vomiting, and an upper abdominal mass which had increased in size over the previous 2 weeks. CT scan showed a partial gastric outlet obstruction secondary to an epigastric hernia. This was assessed further on fluoroscopy, showing the distal stomach in the hernial sac and a delay in gastric emptying. We present the CT and fluoroscopic findings of this rare cause of gastric outlet obstruction.

Introduction: Acute gastric dilatation (AGD) is a massive distension of the stomach caused by the accumulation of gas, gastric secretions, or food material. AGD is a radiological diagnosis with no clear etiopathogenesis and is often misdiagnosed owing to a lack of clear diagnostic criteria and physician awareness. Case Presentation: In this case series, we describe the clinical presentations and outcomes of 4 patients with AGD. Three (75%) of the patients were female, and one (25%) was male. The patients’ ages ranged from 53 to 84 years, with an average age of 73.5 years. Abdominal pain, nausea, and vomiting were the most frequently reported complaints. Two (50%) patients had cancer, one (25%) had an acquired duodenal stenosis, and the fourth patient experienced an ileus. Conclusion: AGD is a surgical emergency with a 50–100% mortality rate; thus, prompt diagnosis and management are crucial. Herein, we describe a case series of AGDs that were diagnosed and managed at our institution. We aim to raise awareness about this fatal yet underrecognized clinical entity.

Malignant gastric outlet obstruction (GOO) is a condition characterized by blockage or narrowing where the stomach empties its contents into the small intestine due to primary malignant tumors or metastatic diseases. This condition leads to various symptoms such as nausea, vomiting, abdominal pain, and weight loss. To manage malignant GOO, different treatment options have been employed, including surgical gastrojejunostomy (SGJ), gastroduodenal stenting (GDS) using self-expandable metallic stent (SEMS), and endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ). This review focuses on comparing the clinical outcomes of endoscopic stenting (GDS and EUS-GJ) with SGJ for malignant GOO. Studies have shown that GDS with SEMS provides comparable clinical outcomes and safety for the palliation of obstructive symptoms. The choice between covered and uncovered SEMS remains controversial, as different studies have reported varying results. EUS-GJ, performed via endoscopic ultrasound guidance, has shown promising efficacy and safety in managing malignant GOO, but further studies are needed to establish it as the primary treatment option. Comparative analyses suggest that GDS has higher recurrence and reintervention rates compared to EUS-GJ and SGJ, with similar overall procedural complications. However, bleeding rates were lower with GDS than with SGJ. Randomized controlled trials are required to determine the optimal treatment approach for malignant GOO.

Background/purpose: Endoscopic stenting at malignant distal duodenum stenosis (MDDS) is challenging because of the duodenal C-loop configuration, the acute angle of the duodenojejunal junction, and the limited length of the endoscope. Few studies have investigated the clinical outcomes of stenting at the distal duodenum. Therefore, this study aimed to investigate the clinical outcomes of treating MDDS with different types of metallic stents. Methods: From January 2012 to December 2020, fifty-six patients with MDDS who underwent duodenal stenting were enrolled for analysis. Thirty-five patients received uncovered self-expandable metallic stents (UC-SEMS), and twenty-one patients received partially covered self-expandable metallic stents (PC-SEMS). All patients were followed up till death or for 18 months. The clinical success rate, stent dysfunction rate, and stent patency were compared between the groups. Multivariate analysis was conducted to identify factors related to stent dysfunction. Results: The clinical success rates were 85.7 % in both the UC-SEMS and PC-SEMS groups. Stent dysfunction rates (UC-SEMS: 34.3 %, PC-SEMS: 38.1 %, p = 0.773) and the average stent patency (UC-SEMS: 117.2 days, PC-SEMS: 100.0 days, p = 0.576) were not statistically different between the groups. Multivariate analysis disclosed the age ≥65 years was significantly related to stent dysfunction (odds ratio: 4.78, p = 0.031). Conclusion: Both UC-SEMS and PC-SEMS are safe and effective treatment options for MDDS. However, stent dysfunction remains a significant issue to overcome, particularly in the elderly. Further research is needed to explore novel strategies that can improve the effectiveness of stent placement and reduce the risk of stent dysfunction.

Abstract Background Ingestion of foreign bodies may be seen unconsciously or intentionally in patients with mental health problems. Most cases pass through the esophagus slowly; however, in some cases, the tumor may be located in narrower areas of the digestive tract that require endoscopic or surgical intervention. This study describes a rare case of successful removal of more than 450 pieces of metal objects from the stomach of a 36-year-old man via ingestion of foreign bodies at Imam Khomeini Hospital in Ahvaz. Case presentation A 36-year-old male patient (Aryan race) presented with complaints of chronic abdominal pain, frequent vomiting, and intolerance to liquids and food. The patient’s companions mentioned a history of gradual ingestion of small metal objects 3 months prior. The patient was conscious and had stable vital signs. In the patient’s X-ray and endoscopy, multiple metal objects inside the patient’s stomach were observed, causing gastric outlet obstruction. The patient underwent gastrostomy surgery, and 452 screws, nuts, keys, stones, and other metal parts weighing 2900 g were removed from the stomach. Five days after the operation, the patient was transferred to the psychiatric service in good general condition and was diagnosed with psychosis, and her condition returned to normal at follow-up. Conclusion Successful removal of this foreign body is rare. In chronic abdominal pain, especially in the context of psychiatric disorders, attention should be given to the ingestion of foreign bodies. In swallowing large amounts of sharp and metallic foreign objects, surgical intervention is necessary, especially in cases of obstruction, and saves the patient’s life.

Abstract Background Gastric adenomyoma is a rare benign tumor composed of glandular structures and smooth muscle fibers. While some classify gastric adenomyoma as a hamartoma, others view it as an abortive form of heterotopic pancreas. Despite its benign nature, there is a risk of malignant transformation. Predominantly found in the antrum, gastric adenomyoma affects all ages but is most common in adults aged 40–60 years. Symptoms are nonspecific, and its similarity to other lesions complicates diagnosis. This paper aims to provide a review of medical literature on gastric adenomyoma and its diagnosis and treatment methods, along with presenting an additional case report on the same topic. Case presentation We present the case of a 55-year-old Syrian man who experienced vomiting, weight loss, and chronic partial constipation. An obstructing mass in the pylorus was detected, and then an open surgery was performed to excise the lesion. A biopsy of the resected mass was obtained for histopathological examination. The final diagnosis of the lesion was pyloric-region adenomyoma with severe pyloric stenosis. After the successful surgery, the patient recovered without any recurrence or complications. Conclusions Several diagnostic approaches are available, including radiological studies, endoscopic examination, and fine needle aspiration guided by endoscopic ultrasonography. Treatment options involve endoscopic submucosal dissection and complete laparotomy resection. Further studies and thorough reviews are recommended to better understand the best clinical practices. Practitioners should consider gastric adenomyoma when encountering a mural gastric lesion.

Simple Summary: Delayed gastric conduit emptying (DGCE) is a common complication of esophageal surgery. The current study compares three endoscopic procedures—Intra-Pyloric Injection of Botulinum Toxin (IPBT), Pneumatic Balloon Dilation (PBD), and a combination of both in the same session (BTPD)—to determine which approach is the most effective in DGCE treatment. By analyzing data from 64 patients endoscopically treated, results showed that the combination approach (BTPD) was associated with a higher rate of symptom resolution. BTPD allowed patients to resume eating and be discharged more quickly. These findings suggest that BTPD may be the most effective treatment for DGCE, offering better patient outcomes and potentially guiding future treatment strategies. Background/Objectives: Delayed gastric conduit emptying (DGCE) occurs in 15–39% of patients who undergo esophagectomy. Intra-Pyloric Injection of Botulinum Toxin (IPBT), Pneumatic Balloon Dilation (PBD), and the same session combination (BTPD) represent the main endoscopic procedures, but comparative data are currently unavailable. Methods: We retrospectively analyzed prospectively collected data on all consecutive patients with DGCE treated endoscopically with IPBT, PBD, or BTPD. ISDE Diagnostic Criteria were used for DGCE diagnosis and classification. A Gastric Outlet Obstruction Score was used for clinical staging. All patients undergoing IPBT received 100 UI of toxin, while those undergoing PBD were dilated up to 20 mm. Clinical success (CS) was defined as the resolution of symptoms/resumption of feeding at discharge or expanding dietary intake at any rate. Recurrence was defined as symptom relapse after more than 15 days of well-being requiring endoscopic/surgical intervention. Results: A total of 64 patients (81.2% male, 90.6% Ivor-Lewis esophagectomy, 77.4% adenocarcinoma) with a median age of 62 years (IQR 55–70) were enrolled: 18 (28.1%) in the IPBT group, 24 (37.5%) in the PBD group, and 22 (34.4%) in the BTPD group. No statistically significant differences were found in the baseline characteristics, surgical techniques, and median follow-up among the three groups. BTPD showed a higher CS rate (100%) compared to the PD and BTPD groups (p = 0.02), and a Kaplan–Meier analysis with a log–rank test revealed that the BTPD group was associated both with a significatively shorter mean time to refeed of 1.16 days (95% CI 0.8–1.5; p = 0.001) and a shorter median time to discharge of one day (95% CI 1–3; p = 0.0001). Conclusions: Endoscopic management of DGCE remains challenging. Waiting for further strong evidence, BTPD can offer patients a higher clinical efficacy rate and a shorter time to refeed and be discharged. [ABSTRACT FROM AUTHOR]

Objectives Methods Results Conclusion Gastrojejunostomy is a critical procedure for managing gastric outlet obstruction. While surgical gastrojejunostomy has traditionally been the standard approach, endoscopic ultrasound (EUS)‐guided gastroenterostomy has emerged as a promising endoscopic alternative. This comprehensive review aims to explore the development, techniques, outcomes, and comparative effectiveness of EUS‐guided gastroenterostomy in comparison to duodenal stenting and surgical gastrojejunostomy.A comprehensive literature search was conducted using electronic databases to identify relevant studies published up to April 2024. The search included keywords related to EUS‐guided gastrojejunostomy, surgical gastrojejunostomy, and duodenal stenting. Studies reporting on technical success, clinical success, complications, recurrence rates, quality of life, and long‐term outcomes were included for analysis.The development of EUS‐guided gastroenterostomy has evolved significantly over the years, driven by device advancements and improved endoscopic techniques. Comparative studies have shown that the technique offers several advantages, including the ability to create an anastomosis without the need for surgery, reduced invasiveness, shorter hospital stays, and potentially improved patient outcomes as compared to duodenal stenting and surgical gastrojejunostomy.Endoscopic ultrasound‐guided gastroenterostomy represents a promising alternative to surgical gastrojejunostomy and duodenal stenting for the management of gastric outlet obstruction. The technique has evolved significantly, offering a less invasive and more effective treatment option. [ABSTRACT FROM AUTHOR]

Key Clinical Message: Isolated gastric outlet obstruction secondary to breast carcinoma is a rare and often challenging diagnosis. Clinicians must be cognizant of this diagnosis even in cases where breast cancers have been in remission alongside more common causes of mechanical obstruction including pancreatic and gastric carcinomas and peptic ulcer disease.

Simple Summary: The aim of our retrospective study was to compare EUS-guided gastroenteroanastomosis (EUS-GE) and enteral stenting (ES) for the palliation of gastric outlet obstruction (GOO) in patients already treated with EUS-guided choledocoduodenostomy (EUS-CDS) for distal malignant biliary obstruction (DMBO). Our results on 77 patients demonstrated that both EUS-GE and ES are safe and effective for palliation of GOO, but EUS-GE is associated with less recurrence of symptoms. Background: EUS-guided gastroenterostomy (EUS-GE) is a novel and effective procedure for the management of malignant gastric outlet obstruction (GOO) with more durable results when compared to enteral stenting (ES). However, data comparing EUS-GE to ES in patients already treated with EUS-guided choledocoduodenostomy (EUS-CDS) for distal malignant biliary obstruction (DMBO) are lacking. We aimed to compare outcomes of EUS-GE and ES for the palliation of GOO in this specific population of patients. Methods: A multicenter, retrospective analysis of patients with DMBO treated by EUS-CDS and subsequent GOO treated by EUS-GE or ES from 2016 to 2021 was conducted. Primary outcomes were overall AEs rate and dysfunction of the EUS-CDS after GOO treatment. Secondary outcomes included clinical success, technical success, procedure duration, length of hospital stay and relapse of GOO symptoms. Results: A total of 77 consecutive patients were included in the study: 25 patients underwent EUS-GE and 52 underwent ES. AEs rate and patency outcomes of the EUS-CDS after GOO treatment were comparable between the two groups (12.5% vs. 17.3%; p = 0.74). No recurrence of GOO symptoms was registered in the EUS-GE group while 11.5% of ES patients had symptoms recurrence, even if not statistically significant (p = 0.16), after a mean follow-up period of 63.5 days. Conclusion: EUS-GE and ES are both effective and safe for the palliation of GOO in patients already treated by EUS-CDS for DMBO with no difference in the biliary stent dysfunction rate and overall AEs. EUS-GE is associated with less recurrence of GOO symptoms. [ABSTRACT FROM AUTHOR]

Background The optimal treatment for malignant gastric outlet obstruction (GOO) remains uncertain. This systematic review aimed to comprehensively investigate the efficacy and safety of four palliative treatments for malignant GOO: gastrojejunostomy, endoscopic ultrasound-guided gastroenterostomy (EUS-GE), stomach-partitioning gastrojejunostomy (PGJ), and endoscopic stenting. Methods We searched PubMed, Embase, Cochrane Library, Scopus, and Web of Science databases, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform for randomized controlled trials (RCTs) and cohort studies comparing the four treatments for malignant GOO. We included studies that reported at least one of the following clinical outcomes: clinical success, 30-day mortality, reintervention rate, or length of hospital stay. Evidence from RCTs and non-RCTs was naïve combined to perform network meta-analysis through the frequentist approach using an inverse variance model. Treatments were ranked by P score. Results This network meta-analysis included 3617 patients from 4 RCTs, 4 prospective cohort studies, and 32 retrospective cohort studies. PGJ was the optimal approach in terms of clinical success and reintervention (P scores: 0.95 and 0.90, respectively). EUS-GE had the highest probability of being the optimal treatment in terms of 30-day mortality and complications (P scores: 0.82 and 0.99, respectively). Cluster ranking to combine the P scores for 30-day mortality and reintervention indicated the benefits of PGJ and EUS-GE (cophenetic correlation coefficient: 0.94; PGJ and EUS-GE were in the same cluster). Conclusion PGJ and EUS-GE are recommended for malignant GOO. PGJ could be the alternative choice in centers with limited resources or in patients who are unsuitable for EUS-GE.

Bouveret's syndrome, a rare complication of gallstone disease, poses a significant diagnostic and therapeutic challenge, particularly in elderly individuals with multiple comorbidities. The mortality rate ranges from 12-30%, emphasizing the importance of prompt and accurate diagnosis. Nonspecific symptoms, such as nausea, vomiting, and abdominal pain, contribute to delayed diagnosis. Healthcare professionals, especially those involved in gastroenterology and surgery, require comprehensive education on Bouveret's syndrome. Training should emphasize the diverse diagnostic modalities, including the use of imaging techniques such as X-rays, ultrasound, and MRI. Awareness of the syndrome's rarity and collaboration among specialists from various fields are crucial for effective management. Additionally, educational programs should underscore the need for individualized treatment plans, considering patient parameters such as age, comorbidities, and the inflammatory state of surrounding tissues. While endoscopic procedures exhibit lower success rates, they are often preferred due to the high risk associated with open surgical procedures in elderly patients. Continuous medical education should also highlight the potential link between diabetes and Bouveret's syndrome, emphasizing the importance of recognizing risk factors and ensuring timely medical intervention. In conclusion, enhancing the knowledge base of healthcare professionals through targeted education is essential for improving the diagnosis and management of Bouveret's syndrome, ultimately contributing to better patient outcomes.

Introduction: We aimed at evaluating the safety and efficacy of self-expandable metallic stent (SEMS) insertion for managing patients with benign gastric outlet obstruction (GOO). Methods: This prospective interventional study included 23 patients. All consecutive treatment-naïve symptomatic patients with benign GOO were recruited. Fully covered SEMS were deployed across the stricture under fluoroscopic and endoscopic guidance. Technical success, clinical success and sustained treatment response (STR) were assessed. Technical success was defined as the successful deployment of SEMS at the desired anatomic location. Clinical success was defined as the resolution of symptoms and an increase in Gastric Outlet Obstruction Scoring System (GOOSS) of at least 1 point from the baseline score on Day 7. STR was assessed at four and eight weeks post stent removal in patients who had a response at week four. Factors associated with stent migration and non-response at week four were also assessed. Results: The median age of the study population was 30 years (range 19–65 years). Males constituted 65.22%. Most patients presented with vomiting (100%) and abdominal pain (95.65%). Peptic stricture was most common etiology for GOO (60.9%) followed by tubercular (26.1%) and corrosive (13%). Most common site of obstruction was junction of first and second part of duodenum (69.57%) followed by pyloric (30.43%). Median length of stricture was 2 cm (range 1.5–4). Technical success was achieved in all 23 patients (100%). Clinical success was achieved in 21 patients (91.3%). Response at Day 28 was seen in 20 patients (86.95%). Eighteen of 20 (90%) patients who had a response at week four had STR at week four and week eight after stent removal. Stent migration occurred in five (21.7%) patients. On univariate analysis, stricture length, calibre and stent length were found to predict migration. Conclusions: Fully covered SEMS was an effective and safe management modality in patients with benign GOO. Stent migration remains a troublesome disadvantage. [ABSTRACT FROM AUTHOR]

Objectives Methods Results Conclusion Endoscopic ultrasound‐guided gastrojejunostomy (EUS‐GJ) is an alternative to duodenal stenting and surgical GJ (SGGJ) in malignant gastric outlet obstruction (MGOO). European Society of Gastrointestinal Endoscopy guidelines restricted EUS‐GJ for MGOO only, because of misdeployment. The aim was to evaluate its outcomes focusing on benign indications.This was a retrospective study conducted from 2016 to 2023 in a tertiary center. Patients included had malignant or benign GOO indicated for EUS‐GJ. Techniques were the direct approach until August 2021, and the wire endoscopic simplified technique (WEST) afterwards. The main objective was to compare outcomes in benign vs. MGOO. Secondary end‐points were technical success, adverse events rates, and describing the evolution of techniques and indications.In all, 87 patients were included, 46 men, mean age 66 ± 16.2 years. Indications were malignant in 60.1% and benign in 39.1%. The EUS‐GJ technique was direct in 33 patients (37.9%) and WEST in 54 (62.1%). No difference was found in terms of technical, clinical, or adverse events rates. The initial technical success rate was 88.5%. The final technical and clinical success rates were 96.6% and 94.25%, respectively. In the last year, benign exceeded malignant indications (70.4% vs. 29.6%, P < 0.05). Seven misdeployments occurred, six being addressed with the rescue technique. The misdeployment rate was significantly decreased using the WEST approach compared to the direct one: 3.7% vs. 18% (P < 0.05). The severe postoperative adverse events rate was 2.3%.This study demonstrated similar outcomes of EUS‐GJ between benign and MGOO, with a decreasing misdeployment rate (<4%) applying WEST. This represents an additional step towards recommending EUS‐GJ in benign indications. [ABSTRACT FROM AUTHOR]

Endoscopic ultrasound (EUS) is increasingly used as a therapeutic approach for gastrointestinal diseases, especially with the advent of lumen‐apposing metal stents (LAMS). This has led to a rise in of EUS‐guided gastrointestinal anastomosis procedures. Due to the reliability of intestinal conduits with LAMS, indications for EUS‐guided gastrointestinal anastomosis are becoming more common and trend to potentially be standard care for gastric outlet obstruction, afferent loop syndrome, and EUS‐directed transgastric interventions such as EUS‐directed endoscopic retrograde cholangiopancreatography. Retrospective and prospective data indicate that the procedure is becoming widely adopted with promising outcomes. This article aims to review the existing literature on EUS‐guided gastrointestinal anastomosis and predict its future developments. [ABSTRACT FROM AUTHOR]

Background/Aims: Advanced pancreatic and biliary tract cancers can invade the duodenum and cause duodenal hemorrhagic stenosis. This study aimed to evaluate the efficacy of covered self-expandable metal stents in the treatment of cancer-related duodenal hemorrhage with stenosis. Methods: Between January 2014 and December 2016, metal stents were placed in 51 patients with duodenal stenosis. Among these patients, a self-expandable covered metal stent was endoscopically placed in 10 patients with hemorrhagic duodenal stenosis caused by pancreatobiliary cancer progression. We retrospectively analyzed the therapeutic efficacy of the stents by evaluating the technical and clinical success rates based on successful stent placement, degree of oral intake, hemostasis, stent patency, and overall survival. Results: The technical and clinical success rates were 100%. All 10 patients achieved a gastric outlet obstruction scoring system score of three within two weeks after the procedure and had no recurrence of melena. The median stent patency duration and overall survival after stent placement were 52 days (range, 20-220 days) and 66.5 days (range, 31-220 days), respectively. Conclusions: Endoscopic placement of a covered metal stent for hemorrhagic duodenal stenosis associated with pancreatic or biliary tract cancer resulted in duodenal hemostasis, recanalization, and improved quality of life.

Background: Gastric adenomyoma is a rare benign tumor composed of glandular structures and smooth muscle fibers. While some classify gastric adenomyoma as a hamartoma, others view it as an abortive form of heterotopic pancreas. Despite its benign nature, there is a risk of malignant transformation. Predominantly found in the antrum, gastric adenomyoma affects all ages but is most common in adults aged 40–60 years. Symptoms are nonspecific, and its similarity to other lesions complicates diagnosis. This paper aims to provide a review of medical literature on gastric adenomyoma and its diagnosis and treatment methods, along with presenting an additional case report on the same topic. Case presentation: We present the case of a 55-year-old Syrian man who experienced vomiting, weight loss, and chronic partial constipation. An obstructing mass in the pylorus was detected, and then an open surgery was performed to excise the lesion. A biopsy of the resected mass was obtained for histopathological examination. The final diagnosis of the lesion was pyloric-region adenomyoma with severe pyloric stenosis. After the successful surgery, the patient recovered without any recurrence or complications. Conclusions: Several diagnostic approaches are available, including radiological studies, endoscopic examination, and fine needle aspiration guided by endoscopic ultrasonography. Treatment options involve endoscopic submucosal dissection and complete laparotomy resection. Further studies and thorough reviews are recommended to better understand the best clinical practices. Practitioners should consider gastric adenomyoma when encountering a mural gastric lesion. [ABSTRACT FROM AUTHOR]

Background: Ingestion of foreign bodies may be seen unconsciously or intentionally in patients with mental health problems. Most cases pass through the esophagus slowly; however, in some cases, the tumor may be located in narrower areas of the digestive tract that require endoscopic or surgical intervention. This study describes a rare case of successful removal of more than 450 pieces of metal objects from the stomach of a 36-year-old man via ingestion of foreign bodies at Imam Khomeini Hospital in Ahvaz. Case presentation: A 36-year-old male patient (Aryan race) presented with complaints of chronic abdominal pain, frequent vomiting, and intolerance to liquids and food. The patient's companions mentioned a history of gradual ingestion of small metal objects 3 months prior. The patient was conscious and had stable vital signs. In the patient's X-ray and endoscopy, multiple metal objects inside the patient's stomach were observed, causing gastric outlet obstruction. The patient underwent gastrostomy surgery, and 452 screws, nuts, keys, stones, and other metal parts weighing 2900 g were removed from the stomach. Five days after the operation, the patient was transferred to the psychiatric service in good general condition and was diagnosed with psychosis, and her condition returned to normal at follow-up. Conclusion: Successful removal of this foreign body is rare. In chronic abdominal pain, especially in the context of psychiatric disorders, attention should be given to the ingestion of foreign bodies. In swallowing large amounts of sharp and metallic foreign objects, surgical intervention is necessary, especially in cases of obstruction, and saves the patient's life. [ABSTRACT FROM AUTHOR]

Background: Recently, endoscopic ultrasound-guided (EUS) gastrojejunostomy (GJ) has emerged as an alternative option to surgical palliation and endoscopic duodenal stenting for malignant gastric outlet obstruction (GOO). Although early success rates are commonly reported with the technique, there is a paucity of data regarding the long-term efficacy of this approach. In this study, we investigated long-term outcomes in patients that underwent EUS-guided GJ for palliation of periampullary malignancies. Methods: From a total of 192 studies that were reviewed, 6 studies with a follow-up time frame of a minimum of 5 months were analyzed, totaling 238 patients. Outcome variables included technical success rate, clinical success rate, adverse events, symptom recurrence, and re-intervention rates. Results: The cohort of 238 patients had a technical success rate of 93.7% and a clinical success rate of 92.9%. A total of 25 patients (10.5%) experienced adverse events associated with EUS-GJ. A total of 14 patients (5.9%) experienced recurrence of GOO symptoms within 5 months. A total of 14 patients (5.9%) underwent re-intervention with the first 5 months. Conclusions: This systematic review shows that data are scarce regarding long-term effectiveness of EUS-guided GJ. Even though early success rates have been reported, further studies are needed to focus on long-term efficacy of this approach. Until such studies become available, surgical palliation should continue to be the treatment of choice for patients with malignant GOO with a prolonged life expectancy. [ABSTRACT FROM AUTHOR]

Objective: To develop and validate a simple prediction model to diagnose female bladder outlet obstruction (fBOO) because of the invasive nature of standard urodynamic studies (UDS) for diagnosing fBOO. Methods: We retrospectively analyzed the data of 728 women who underwent UDS at Tongji Hospital between 2011 and 2021. The definition of fBOO was Pdet.Qmax − 2.2 × Qmax > 5 (BOOIf > 5). Independent predictive factors of fBOO were determined by multivariable logistic regression analysis. These predictive factors were incorporated into a predictive model to assess the risk of fBOO. Results: Of the 728 patients, 249 (34.2%) were identified as having fBOO and these women were randomly assigned to two groups, a model development group and a model validation group. Multivariate logistic regression demonstrated that age, Qmax, flow time, and voiding efficiency were independent risk factors for fBOO. The predictive model of fBOO showed a satisfactory performance, with area under the curve being 0.811 (95% confidence interval [CI] 0.771–0.850, P < 0.001), which was confirmed to be 0.820 (95% CI 0.759–0.882, P < 0.001) with external validation. The calibration curve indicated that the predicted probability had an excellent correspondence to observed frequency. Decision curve analysis demonstrated a greater clinical net benefit compared with the strategies of treat all or treat none when the predicted risk was in a range of 3% and 75%. Conclusion: A novel predictive model of fBOO was developed and validated based on clinical features and noninvasive test parameters in female patients with lower urinary tract symptoms. The model is a quick and easy‐to‐use tool to assess the risk of fBOO for urologists in their routine practice without an invasive UDS. Synopsis: A noninvasive predictive model for diagnosing female bladder outlet obstruction was developed and validated by incorporating age, Qmax, flow time, and voiding efficiency.

The therapeutic possibilities of endoscopy have rapidly increased in the last decades and now allow organ-sparing treatment of early upper gastrointestinal malignancy as well as an increasing number of options for symptom palliation. This review contains an overview of the interventional endoscopic procedures in upper gastrointestinal malignancies. It describes endoscopic treatment of early oesophageal and gastric cancers, and the palliative options in managing dysphagia and gastric outlet obstruction. It also provides an overview of the therapeutic possibilities of biliary endoscopy, such as retrograde stenting and radiofrequency biliary ablation. Endoscopic ultrasound-guided therapeutic options are discussed, including biliary drainage, gastrojejunostomy and coeliac axis block. To aid in clinical decision making, the procedures are described in the context of their indication, efficacy, risks and limitations. • Endoscopy now offers curative treatments for early oesophageal and gastric cancer. • Interventional endoscopy can offer effective symptom palliation for dysphagia, pain and jaundice. • Duodenal stents and EUS-guided interventions provide effective palliation in gastric obstruction.

Introduction: Gastric outlet obstruction (GOO) is a common complication in advanced stage upper gastrointestinal malignancies. The symptoms of severe nausea and protracted vomiting can lead to a decline in quality of life and cachexia. Symptoms of GOO can be effectively managed with either operative or nonoperative palliative interventions. In our article, we aim to compare laparoscopic gastrojejunostomy (GJ) to endoscopic stenting as palliative interventions for GOO. Methods: We retrospectively evaluated the charts of patients who underwent palliative procedure for gastric outlet obstruction. Group I included patients who underwent endoscopic stenting, and group II patients underwent Laparoscopic GJ. The groups' demographics (age, gender), length of procedure, length of stay, days to oral intake, overall survival, complications rate, and 30-day mortality rates were compared. Results: Overall, 38 patients were included in the study. Nineteen patients underwent endoscopic stenting and 19 underwent laparoscopic GJ. Comparing the groups, no significant differences were noted. Surgical time was significantly longer than the endoscopic procedures (83 minutes versus 25 minutes, P =.001). No significant differences were noted in days of oral intake initiation, overall survival and 30-day mortality rates. Five patients in the stenting group had complications (26.3%) versus none in the surgical group (P =.046). No postoperative complications were noted. Conclusion: Laparoscopic GJ is a safe and feasible treatment for GOO, demonstrating early resumption of oral intake. The relative short hospital stay, combined with an encouraging postoperative complications profile and low reintervention rate, should be kept in mind especially among patients with longer life expectancy.

Endoscopic stenting at malignant distal duodenum stenosis (MDDS) is challenging because of the duodenal C-loop configuration, the acute angle of the duodenojejunal junction, and the limited length of the endoscope. Few studies have investigated the clinical outcomes of stenting at the distal duodenum. Therefore, this study aimed to investigate the clinical outcomes of treating MDDS with different types of metallic stents. From January 2012 to December 2020, fifty-six patients with MDDS who underwent duodenal stenting were enrolled for analysis. Thirty-five patients received uncovered self-expandable metallic stents (UC-SEMS), and twenty-one patients received partially covered self-expandable metallic stents (PC-SEMS). All patients were followed up till death or for 18 months. The clinical success rate, stent dysfunction rate, and stent patency were compared between the groups. Multivariate analysis was conducted to identify factors related to stent dysfunction. The clinical success rates were 85.7 % in both the UC-SEMS and PC-SEMS groups. Stent dysfunction rates (UC-SEMS: 34.3 %, PC-SEMS: 38.1 %, p = 0.773) and the average stent patency (UC-SEMS: 117.2 days, PC-SEMS: 100.0 days, p = 0.576) were not statistically different between the groups. Multivariate analysis disclosed the age ≥65 years was significantly related to stent dysfunction (odds ratio: 4.78, p = 0.031). Both UC-SEMS and PC-SEMS are safe and effective treatment options for MDDS. However, stent dysfunction remains a significant issue to overcome, particularly in the elderly. Further research is needed to explore novel strategies that can improve the effectiveness of stent placement and reduce the risk of stent dysfunction. [ABSTRACT FROM AUTHOR]

Endoscopic bariatric therapies can provide treatment options for obesity in non-surgical candidates, as a part of combination or serial treatment plans, and for the reduction of obesity-related comorbidities. Several complications of intragastric balloons have been documented, but spontaneous hyperinflation is a risk that has not been well reported previously. We describe two cases of spontaneous intragastric balloon hyperinflation and their outcomes. [ABSTRACT FROM AUTHOR]

Endoscopic stenting is an area of endoscopy that has witnessed noteworthy advancements over the last decade, resulting in evolving clinical practices among gastroenterologists around the world. Indications for endoscopic stenting have progressively expanded, becoming a frequent part of the management algorithm for various benign and malignant conditions of the gastrointestinal tract, from esophagus to rectum. In addition to expanded indications, continuous technological enhancements and development of novel endoscopic stents have resulted in an increased success of these approaches and, in some cases, allowed new applications. This review aimed to summarize best practices in esophageal, gastroduodenal, and colonic stenting.

Endoscopic or fluoroscopic guided naso-enteric placement for stenting and decompression has been used in mechanical enteric limb obstruction after gastrectomy or gastric bypass surgery. However, the use of double naso-enteric tube for treatment of multiple enteric limbs obstruction has not been described to date. We present a 61-year-old female with afferent limb syndrome with concomitant efferent limb obstruction which caused by kinking of anastomosis after loop gastrojejunostomy for benign gastric outlet obstruction. Two naso-enteric tubes were placed in efferent limb and afferent limb by endoscopic and fluoroscopic guidance. The patient was able to resume oral intake after 2 weeks of tube placement.

Gastric outlet obstruction (GOO) is a clinical syndrome characterized by hindrance in the passage of gastric contents into the duodenum, with various etiologies including bezoars. Phytobezoars, composed of undigested food fibers, represent a rare but significant cause of GOO. Herein, we present a case of a 34-year-old female with recurrent vomiting and early satiety, diagnosed with GOO caused by an impacted phytobezoar in the duodenum. Despite initial unsuccessful attempts at endoscopic removal, alternative techniques led to successful extraction. Postprocedure evaluation revealed a large duodenal diverticulum. Our experience underscores the complexity of managing duodenal phytobezoars and highlights the efficacy of combined therapeutic approaches. Heightened awareness among gastroenterologists regarding this condition is essential to optimize patient outcomes. Recurrence prevention strategies include dietary modifications and periodic endoscopic interventions for challenging cases. [ABSTRACT FROM AUTHOR]
