ENDOSCOPIC ULTRASONOGRAPHY

BACKGROUND: Transaxillary endoscopic thyroidectomy (TAET) is favored for its favorable cosmetic outcomes and the preservation of anterior cervical function. Despite these benefits, postoperative analgesia has traditionally relied on pharmacological interventions, and regional anesthetic procedures may be an alternative method. This study aimed to evaluate the efficacy of an ultrasound-guided pectoserratus plane block (PSPB) combined with an intermediate cervical plexus block (ICPB) for TAET...

BACKGROUND: Gastric hamartomatous inverted polyps (GHIPs) are not well characterized and remain diagnostically challenging due to rarity. Therefore, this study aims to investigate the clinicopathologic and endoscopic characteristics of patients with GHIP. METHODS: We retrospectively reviewed clinicopathologic and endoscopic features of ten patients with GHIP who were admitted to Beijing Friendship Hospital from March 2013 to July 2022. All patients were treated successfully by endoscopic resection...

BACKGROUND: Malignant Gastric Outlet Obstruction (mGOO) has been standardly treated by surgical Gastrojejunostomy (S-GJ) or Endoscopic Stenting (ES). Recently, EUS-Gastrojejunostomy (EUS-GJ) has emerged as an alternative, despite its worldwide diffusion is heterogeneous. The aim of this survey was to assess clinical decision-making around mGOO and to explore current opinions regarding EUS-GJ. METHODS: An online survey, spread through social networks and EPC newsletter, was created exploring opinions regarding indications, contraindications, benefits/risks, availability of mGOO treatments; 2 case vignettes explored clinical decision-making in different scenarios...

BACKGROUND AND AIMS: Endoscopic multiple plastic stents are an established first-line treatment for anastomotic biliary stricture (ABS) management after liver transplantation (LT). Fully covered self-expandable metallic stents (FCSEMSs) have recently been used with favorable outcomes, but long-term treatment outcomes remain an issue for ABS. We evaluated the long-term outcomes of FCSEMS for the management of refractory ABS after LT. METHODS: We reviewed the prospectively collected and maintained endoscopic retrograde cholangiography database at Asan Medical Center to retrieve consecutive post-LT ABS cases that underwent an endoscopic FCSEMS placement between August 2009 and August 2019 after MPS placement failure...

BACKGROUND: Studies have evaluated the efficacy of endoscopic incisional therapy (EIT) for benign anastomotic strictures. We performed a systematic review and meta-analysis to evaluate stricture recurrence after EIT following esophagectomy or gastrectomy. METHODS: A systematic search of databases was performed up to April 2nd, 2023, after selection of key search terms with the research team. Inclusion criteria included human participants undergoing EIT for a benign anastomotic stricture after esophagectomy or gastrectomy, age ≥ 18, and n ≥ 5...

Gastrointestinal (GI) endoscope is one of the instruments used extensively in the diagnosis and treatment of digestive tract disorders. China is confronted with a great demand for endoscopists working in grassroots healthcare facilities. Furthermore, endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasonography (EUS), and endoscopic submucosal dissection (ESD) are becoming the prevailing methods of endoscopic treatment of digestive diseases. Therefore, there is a growing demand for senior endoscopists...

BACKGROUND: Even in cancer of unknown primary (CUP), which is rare clinical condition, solitary anterosuperior lymph node (LN) along the common hepatic artery (No.8a LN) enlargement diagnosed as metastatic adenocarcinoma has never been reported. CASE PRESENTATION: A 68-year-old Japanese male, with a history of early gastric cancer that had been completely treated by endoscopic submucosal dissection 26 years ago, was detected a single enlarged nodule along the common hepatic artery, No...

BACKGROUND: Hepatic artery infusion pump (HAIP) with floxuridine/dexamethasone and systemic chemotherapy is an established treatment regimen, which had been reported about converting 47% of patients with stage 4 colorectal liver metastasis from unresectable to resectable.1,2 To this effect, HAIP chemotherapy contributes to prolonged survival of many patients, which otherwise may not have other treatment options. Biliary sclerosis, however, is a known complication of the HAIP treatment, which occurs in approximately 5...

BACKGROUND: Large language model (LLM)-linked chatbots may be an efficient source of clinical recommendations for healthcare providers and patients. This study evaluated the performance of LLM-linked chatbots in providing recommendations for the surgical management of gastroesophageal reflux disease (GERD). METHODS: Nine patient cases were created based on key questions addressed by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) guidelines for the surgical treatment of GERD...

BACKGROUND: Leaks following bariatric surgery, while rare, are potentially fatal due to risk of peritonitis and sepsis. Anastomotic leaks and gastro-gastric fistulae following Roux-En-Y gastric bypass (RYGB) as well as staple line leaks after sleeve gastrectomy have historically been treated multimodally with surgical drainage, aggressive antibiotic therapy, and more recently, endoscopically. Endoscopic clipping using over-the-scope clips and endoscopic suturing are two of the most common approaches used to achieve full thickness closure...

Background and study aims Endoscopic ultrasound-directed transgastric intervention (EDGI) is a technique that creates an anastomosis between the gastric pouch or jejunum to the excluded stomach in Roux-en-Y gastric bypass (RYGB) anatomy to allow access to the pancreaticobiliary system. Thus far, management of anastomosis closure at the time of lumen-apposing metal stent (LAMS) removal has varied widely. This study aimed to assess the efficacy of primary closure at the time of LAMS removal using a through-the-scope (TTS) tack-based suture system...

BACKGROUND AND AIM: The microsurface structure reflects the degree of damage to the glands, which is related to the invasion depth of early gastric cancer. To evaluate the diagnostic value of quantitative microsurface structure analysis for estimating the invasion depth of early gastric cancer. METHODS: White-light imaging and narrow-band imaging (NBI) endoscopy were used to visualize the lesions of the included patients. The area ratio and depth-predicting score (DPS) of each patient were calculated; meanwhile, each lesion was examined by endoscopic ultrasonography (EUS)...

BACKGROUND: Endoscopic submucosal dissection (ESD) requires high endoscopic technical skills, and trainees should develop effective training methods. In collaboration with KOTOBUKI Medical, we developed the G-Master, which is a non-animal training model that can simulate various parts of gastric ESD. We aimed to clarify the usefulness of the G-Master for inexperienced ESD trainees. METHODS: We collected data from the first 5 gastric ESD cases conducted by 15 inexperienced ESD trainees at 5 participating centers between 2018 and 2022...

BACKGROUND AND AIMS: This pilot study aimed to evaluate safety and tissue sampling from subepithelial lesions (SEL) in the upper gastrointestinal tract with a novel electric motor driven endoscopic ultrasonography (EUS)-guided 17-gauge (G) size core needle biopsy (CNB) instrument. METHODS: An investigator-led prospective open label, performance and safety control study, including seven patients (female n  = 4, median 71 y, range 28-75) with a determined SEL (median size 30 mm, range 17-150 mm) in the upper digestive tract (stomach n  = 6, duodenum n  = 1) were eligible and later followed up 14 days after index procedure...

BACKGROUND: The preoperative pathological diagnosis of rectal lesions is crucial for formulating treatment plans. For subepithelial lesions (SELs) and larger lesions with necrosis of the rectum, endoscopic forceps biopsy (EFB) cannot provide an accurate pathological diagnosis in most cases. By comparing the efficacy and safety of transrectal contrast-enhanced ultrasound-guided transperineal core-needle biopsy (TRCEUS-TP-CNB) and EFB, this study explored the value of TRCEUS-TP-CNB in the diagnosis of complex rectal lesions, such as SELs...

This review describes the appearance of extrapulmonary tuberculosis manifestations in comprehensive and multiparametric ultrasound imaging. The aim is to increase awareness of typical ultrasound findings regarding extrapulmonary tuberculosis, correlate those with pathological features, and facilitate differential diagnosis. Point of care ultrasound protocols can be used as a screening method in high-risk populations, although the negative findings do not exclude tuberculosis. Conversely, the diagnosis of extrapulmonary tuberculosis can never be made using ultrasound alone, as many ultrasound findings in extrapulmonary tuberculosis are non-specific...

Gastric duplication cysts (GDCs) in adults are exceedingly rare, with only a few documented cases in medical literature. The spectrum of clinical presentations varies widely, ranging from asymptomatic to severe symptoms such as hematemesis, vomiting or abdominal pain. Among the less common complications associated with GDCs, segmental portal hypertension is a notable rarity. We present a compelling case report of a patient exhibiting signs of segmental portal hypertension, where ultrasound and echo-endoscopy revealed a sizable gastric duplication cyst as the underlying etiology...

BACKGROUND: Repeated episodes of jaundice and pruritus are common in a group of autosomal recessive liver diseases known as benign recurrent intrahepatic cholestasis. Benign recurrent intrahepatic cholestasis (BRIC) is divided into two types, type 1 and type 2, and is caused by mutations in the ATP8B1 and ABCB11 genes. Here, we report a rare case of BRIC type 2 mutation. CASE PRESENTATION: A 45-year-old Chinese man had three frequent episodes of jaundice marked by extensive excoriation and severe pruritis, although he had no prior history of jaundice...

BACKGROUND: To reduce the incidence of seromas, we have adapted the quilting procedure used in open abdominoplasty to the endoscopic-assisted repair of concomitant ventral hernia (VH) and diastasis recti (DR). The aim of this study was to describe the technique and assess its efficacy by comparing two groups of patients operated on with the same repair technique before and after introducing the quilting. METHODS: This retrospective study included data prospectively registered in the French Club Hernie database from 176 consecutive patients who underwent surgery for concomitant VH and DR via the double-layer suturing technique...
