Background
/Aims: To overcome the technical limitations of classic endoscopic resection for gastric gastrointestinal stromal tumors (GISTs), various methods have been developed. In this study, we examined the role and feasibility of clip-and-cut procedures (clip-and-cut endoscopic full-thickness resection [cc-EFTR]) for gastric GISTs.
Methods
Medical records of 83 patients diagnosed with GISTs after endoscopic resection between 2005 and 2021 were retrospectively reviewed. Moreover, clinical characteristics and outcomes were analyzed.
Results
Endoscopic submucosal dissection (ESD) and cc-EFTR were performed in 51 and 32 patients, respectively. The GISTs were detected in the upper third of the stomach for ESD (52.9%) and cc-EFTR (90.6%). Within the cc-EFTR group, a majority of GISTs were located in the deep muscularis propria or serosal layer, accounting for 96.9%, as opposed to those in the ESD group (45.1%). The R0 resection rates were 51.0% and 84.4% in the ESD and cc-EFTR groups, respectively. Seven (8.4%) patients required surgical treatment (six patients underwent ESD and one underwent cc-EFTR,) due to residual tumor (n=5) and post-procedure adverse events (n=2). Patients undergoing R0 or R1 resection did not experience recurrence during a median 14-month follow-up period, except for one patient in the ESD group.
Conclusions
cc-EFTR displayed a high R0 resection rate; therefore, it is a safe and effective therapeutic option for small gastric GISTs.

Background
/Aims: The treatment of superficial esophageal neoplasms (SENs) in cirrhotic patients is challenging and rarely investigated. We evaluated the outcomes of endoscopic submucosal dissection (ESD) to determine the efficacy and safety of treating SENs in patients with liver cirrhosis.
Methods
The baseline characteristics and treatment outcomes of patients who underwent ESD for SENs between November 2005 and December 2017 were retrospectively reviewed.
Results
ESD was performed in 437 patients with 481 SENs, including 15 cirrhotic patients with 17 SENs. En bloc resection (88.2% vs. 97.0%) and curative resection (64.7% vs. 78.9%) rates were not different between the cirrhosis and non-cirrhosis groups (p=0.105 and p=0.224, respectively). Bleeding was more common in cirrhotic patients (p=0.054), and all cases were successfully controlled endoscopically. The median procedure and hospitalization duration did not differ between the groups. Overall survival was lower in cirrhotic patients (p=0.003), while disease-specific survival did not differ between the groups (p=0.85).
Conclusions
ESD could be a safe and effective treatment option for SENs in patients with cirrhosis. Detailed preprocedural assessments are needed, including determination of liver function, esophageal varix status, and remaining life expectancy, to identify patients who will obtain the greatest benefit.

Over-the-Scope Clip in the Treatment of Gastrointestinal Leaks and Perforations
Mike T. Wei, Ji Yong Ahn, Shai Friedland
Clin Endosc 2021;54(6):798-804.   Published online November 30, 2021
DOI: https://doi.org/10.5946/ce.2021.250
AbstractAbstract PDFPubReaderePub
While perforations, postoperative fistulas, and leaks have traditionally led to surgical or interventional radiology consultation for management, the introduction of the over-the-scope clip has allowed increased therapeutic possibilities for endoscopists. While primarily limited to case reports and series, the over-the-scope clip successfully manages gastrointestinal bleeding, perforations, as well as postoperative leaks and fistulas. Retrospective studies have demonstrated a relatively high success rate and a low complication rate. Given the similarity to variceal banding equipment, the learning curve with the over-the-scope clip is rapid. However, given the higher risk of procedures involving the use of the over-the-scope clip, it is essential to obtain the scope in a stable position and grasp sufficient tissue with the cap using a grasping tool and/or suction. From our experience, while closure may be successful in lesions sized up to 3 cm, successful outcomes are obtained for lesions sized <1 cm. Ultimately, given the limited available data, prospective randomized trials are needed to better evaluate the utility of the over-the-scope clip in various clinical scenarios, including fistula and perforation management.

AbstractAbstract PDFPubReaderePub
Background
/Aims: Percutaneous endoscopic gastrostomy (PEG) is usually performed on patients with chronic underlying diseases in the general ward (GW). This study evaluated the clinical outcomes of PEG performed on patients in the surgical intensive care unit (SICU) compared with those of PEG performed in the GW.
Methods
The medical records of 27 patients in the SICU and 263 in the GW, who underwent PEG between January 2013 and July 2017, were retrospectively reviewed.
Results
The median age of the 27 SICU patients was 66 years, and their median body mass index was 21.1 kg/m2. In the SICU group, the median baseline Sequential Organ Failure Assessment (SOFA) score was 4, and the median Acute Physiology and Chronic Health Evaluation II (APACHE II) score was 16. The median interval between surgery and PEG in SICU patients was 30 days, with a PEG failure rate of 3.7%. Acute complications in SICU patients included bleeding (7.4%) and ileus (11.1%), while chronic complications included aspiration pneumonia (7.4%) and tube obstruction (3.7%). The rates of acute and chronic complications did not differ significantly between the SICU and GW groups. The 30-day mortality rate was 14.8% in SICU patients and 5.3% in GW patients (p=0.073).
Conclusions
PEG is a safe and feasible method of enteral feeding for critically ill patients who require ICU care after surgery.

AbstractAbstract PDFPubReaderePub
Background
/Aims: To report the long-term survival and tumor recurrence outcomes in patients with superficial esophageal cancer (SEC) after complete non-curative endoscopic resection (ER).
Methods
We retrieved ER data for 24 patients with non-curatively resected SEC. Non-curative resection was defined as the presence of submucosal and/or lymphovascular invasion on ER pathology. Relevant clinical and tumor-specific parameters were reviewed.
Results
The mean age of the 24 study patients was 66.3±8.3 years. Ten patients were closely followed up without treatment, while 14 received additional treatment. During a mean follow-up of 59.0±33.2 months, the 3- and 5-year survival rates of all cases were 90.7% and 77.6%, respectively. The 5-year overall survival rates were 72.9% in the close observation group and 82.1% in the additional treatment group (p=0.958). The 5-year cumulative incidences of all cases of recurrence (25.0% vs. 43.3%, p=0.388), primary EC recurrence (10.0% vs. 16.4%, p=0.558), and metachronous EC recurrence (16.7% vs. 26.7%, p=0.667) were similar between the two groups.
Conclusions
Patients with non-curatively resected SEC showed good long-term survival outcomes. Given the similar oncologic outcomes, close observation may be an option with appropriate caution taken for patients who are medically unfit to receive additional therapy.

AbstractAbstract PDFPubReaderePub
Background
/Aims: The detection of multifocal lesions is important for the successful management of gastric neoplasms. We investigated the characteristics of missed simultaneous lesions and the reason for the missed diagnoses.
Methods
A total of 140 patients who underwent repeat endoscopy before endoscopic resection between June 2013 and June 2014 were retrospectively reviewed. We classified simultaneous lesions into three groups based on a review of earlier images: group 1, no images of the location of simultaneous lesions were taken; group 2, no corresponding lesion was evident in the previous images; and group 3, simultaneous lesions were visible in the earlier images but a biopsy was not performed.
Results
Simultaneous lesions were found in 12 patients (8.6%) with 13 lesions, comprising 10 dysplasia (76.9%) and three adenocarcinoma (23.1%). Regarding the reasons for missed diagnoses, seven lesions (53.8%) were classified as group 3, five (38.5%) as group 1, and the remaining lesion (7.7%) as group 2. There were no significant differences in the characteristics of the patients with and without simultaneous lesions.
Conclusions
Lesions disregarded or unnoticed during endoscopic examination were the main reason for missed diagnosis of simultaneous lesions. Endoscopists should consider the possibility of simultaneous lesions and attempt to meticulously evaluate the entire gastric mucosa.

AbstractAbstract PDFPubReaderePub
In most cases of ingested foreign bodies, endoscopy is the first treatment of choice. Moreover, emergency endoscopic removal is required for sharp and pointed foreign bodies such as animal or fish bones, food boluses, and button batteries due to the increased risks of perforation, obstruction, and bleeding. Here, we presented two cases that needed emergency endoscopic removal of foreign bodies without sufficient fasting time. Foreign bodies could not be visualized by endoscopy due to food residue; therefore, fluoroscopic imaging was utilized for endoscopic removal of foreign bodies in both cases.

Two Cases of Cerebral Air Embolism That Occurred during Esophageal Ballooning and Endoscopic Retrograde Cholangiopancreatography
Suyeon Park, Ji Yong Ahn, Young Eun Ahn, Sang-Beom Jeon, Sang Soo Lee, Hwoon-Yong Jung, Jin-Ho Kim
Clin Endosc 2016;49(2):191-196.   Published online February 22, 2016

AbstractAbstract PDFPubReaderePub
Cerebral air embolism is an extremely rare complication of endoscopic procedure and often life threatening. We present two cases of cerebral infarction due to air embolization caused by an endoscopic intervention. The first case occurred during esophageal balloon dilatation for the treatment of a stricture of an anastomosis site in a 59-year-old man and the second case occurred during endoscopic papillary balloon dilatation in a 69-year-old man who had distal common bile duct stones. After the procedure, cardiopulmonary instability and altered mental status were observed in both patients, and cerebral air embolism was diagnosed in both cases. Hyperbaric oxygen therapy was started in the first case, and high FiO2 therapy was applied in the second case. Although this complication is rare, patient outcomes can be improved if physicians are aware of this potential complication, and immediately begin proper management.

AbstractAbstract PDFPubReaderePub
Background/Aims

To evaluate the yields and utility of 19-gauge (G) Trucut biopsy (TCB) versus 22 G fine needle aspiration (FNA) for diagnosing gastric subepithelial tumors (SETs).

Methods

We retrieved data for 152 patients with a gastric SET larger than 2 cm who had undergone endoscopic ultrasonography (EUS)-guided 19 G TCB (n=90) or 22 G FNA (n=62). Relevant clinical, tumor-specific, and EUS procedural information was reviewed retrospectively.

Results

A specific diagnosis was made for 76 gastrointestinal stromal tumors (GISTs) and 51 non-GIST SETs. The diagnostic yield of TCB was greater than that of FNA (77.8% vs. 38.7%, p<0.001). The percentage of non-diagnostic specimens (suspicious and insufficient) was significantly lower in the TCB group (6.7% and 15.5%, respectively) than in the FNA group (22.6% and 38.7%, respectively; both p<0.001). TCB accurately diagnosed 90.9% of GISTs and 81.1% of non-GIST SETs, whereas FNA accurately diagnosed 68.8% of GISTs and 14.3% of non-GIST SETs. There were nine technical failures with TCB, and the rate of adverse events did not differ between the groups (TCB vs. FNA, 3.3% vs. 8.1%; p=0.27).

Conclusions

Nineteen-gauge TCB is safe and highly valuable for diagnosing gastric SETs larger than 2 cm if technical failure can be avoided.

AbstractAbstract PDFPubReaderePub
Background/Aims

Percutaneous endoscopic gastrostomy (PEG) is a method of providing enteral nutrition using endoscopy. The PEG techniques differ according to the insertion method, and include the pull type, push type, and introducer type. The aim of this study was to compare the clinical outcomes associated with the pull-type and introducer-type PEG insertion techniques, which included the adverse events, at our tertiary care center in Korea.

Methods

We retrospectively reviewed 141 cases that had undergone PEG insertion at our center from January 2009 to June 2012. The indications for PEG insertion and the acute and chronic complications caused by each type of PEG insertion were analyzed.

Results

The indications for PEG insertion in our cohort included neurologic disease (58.7%), malignancy (21.7%), and other indications (19.6%). Successful PEG insertions were performed on 136 cases (96.5%), and there were no PEG-associated deaths. Bleeding was the most frequent acute complication (12.8%), and wound problems were the most frequent chronic complications (8.8%). There were no statistically significant differences between the pull-type and introducer-type PEG insertion techniques in relation to complication rates in our study population.

Conclusions

PEG insertion is considered a safe procedure. The pull-type and introducer-type PEG insertion techniques produce comparable outcomes, and physicians may choose either of these approaches according to the circumstances.

AbstractAbstract PDFPubReaderePub

Jejunal polypoid arteriovenous malformations (AVMs) and jejunojejunal intussusceptions are both rare. Here, we present the case of a 61-year-old woman who suffered intermittent episodes of abdominal pain over the course of 13 years. A computed tomography scan of her abdomen and pelvis revealed a distal jejunojejunal intussusception. A suspected low density mass was observed at the tip of the intussusception. Treatment comprised laparoscopic small bowel resection with end-to-end jejunostomy. The final diagnosis was a polypoid AVM measuring 5×3.5×3 cm. We suggest that polypoid AVM should be considered as a differential diagnosis in patients presenting with small intestinal neoplasms.

AbstractAbstract PDFPubReaderePub

Although acupuncture is known as a safe procedure that is widely used in many countries, complications including infection, hemorrhage, hematoma, pneumothorax, nerve damage, and cardiac tamponade have been reported. A needle penetrating the stomach after acupuncture, however, is very rare. Here, we report the case of 47-year-old woman who experienced abdominal pain 2 days after receiving acupuncture. Upper gastrointestinal endoscopy identified an approximately 2.5-cm long needle in the posterior wall of the antrum. The needle was removed endoscopically using rat tooth forceps with no complications.

Long-Term Outcome of Extended Endoscopic Submucosal Dissection for Early Gastric Cancer with Differentiated Histology
Ji Yong Ahn, Hwoon-Yong Jung
Clin Endosc 2013;46(5):463-466.   Published online September 30, 2013
DOI: https://doi.org/10.5946/ce.2013.46.5.463
AbstractAbstract PDFPubReaderePub

Endoscopic mucosal resection was introduced in the 1990s, and endoscopic submucosal dissection (ESD) in 2003. Currently, ESD is becoming the main procedure for the resection of early gastric cancer (EGC) and is leading to the development of extended indications for endoscopic resection. Many reports showed that the endoscopic and oncologic outcome of endoscopic treatment in the extended indication group was acceptable in terms of curability and safety. Especially, ESD showed better results to remove extended indication EGCs with relatively high resection rate and low local recurrence rate. However, more long-term follow-up data are needed for clinical application of the extended criteria of ESD due to the risk of lymph node metastasis. We should also keep in mind that accurate diagnosis, characterization of the lesion, and proper appreciation of technical aspects are most essential in therapeutic endoscopy.

AbstractAbstract PDFPubReaderePub

Bezoars are concretions of undigested material and are most often observed in the stomach. They can occur at any site in the gastrointestinal tract; however, duodenal localization is very rare. We report the case of a 71-year-old male who had undergone subtotal gastrectomy with gastroduodenostomy and experienced severe epigastric discomfort, abdominal pain, and vomiting for a few days. An approximately 7×8 cm-sized mass was found on an abdominal computed tomography scan. On following endoscopy, a large bezoar was revealed in the duodenum and was removed using an endoscopic removal technique, assisted by a large amount of Coca-Cola infusion.
