The use of endoscopic submucosal dissection (ESD) for treating undifferentiated-type early gastric cancer is controversial. The objective of this study was to perform a meta-analysis to compare the long-term outcomes of ESD and surgery for undifferentiated-type early gastric cancer.

The PubMed, Cochrane Library, and EMBASE databases were used to search for relevant studies comparing ESD and surgery for undifferentiated-type early gastric cancer. The methodological quality of the included publications was evaluated using the Risk of Bias Assessment tool for Nonrandomized Studies. The rates of overall survival, recurrence, adverse event, and complete resection were determined. Odds ratios (ORs) and 95% confidence intervals (CIs) were also evaluated.

This meta-analysis enrolled five studies with 429 and 1,236 participants undergoing ESD and surgery, respectively. No significant difference was found in the overall survival rate between the ESD and surgery groups (OR, 2.29; 95% CI, 0.98-5.36; p=0.06). However, ESD was associated with a higher recurrence rate and a lower complete resection rate. The adverse event rate was similar between the two groups.

ESD with meticulous surveillance esophagogastroduodenoscopy may be as effective and safe as surgery in patients with undifferentiated-type early gastric cancer. link= find more Further large-scale, randomized, controlled studies from additional regions are required to confirm these findings.

Endoscopic ultrasound (EUS) demonstrated a unilocular cyst located between the pancreas, gastric wall, and left adrenal gland, with a regular wall filled with dense fluid with multiple hyperechoic floating spots. A 19-G needle was used to puncture the cyst, but no fluid could be aspirated. Therefore, EUS-guided through-the-needle biopsy (EUS-TTNB) was performed. Histological analysis of the retrieved fragments revealed a fibrous wall lined by "respiratory-type" epithelium with ciliated columnar cells, consistent with the diagnosis of a bronchogenic cyst. Laparoscopic excision was performed, and the diagnosis was confirmed based on the findings of the surgical specimen. Abdominal bronchogenic cysts are extremely uncommon, and a definitive diagnosis is commonly obtained after the examination of surgical specimens due to the lack of pathognomonic findings on cross-sectional imaging and poor cellularity on EUS-guided fine-needle aspiration cytology. EUS-TTNB is useful for establishing a preoperative histological diagnosis, thus supporting the decision-making process.
The coronavirus disease 2019 (COVID-19) pandemic has necessitated modifications to allow the safe practice of clinical gastroenterology and gastrointestinal endoscopy. This study aimed to investigate the characteristics of clinical gastroenterology and gastrointestinal endoscopy practices during the COVID-19 pandemic in Indonesia.

This cross-sectional study enrolled physician members of the Indonesian Society for Digestive Endoscopy. We used an online self-administered questionnaire disseminated via social media. The 32-item survey determined the baseline characteristics of the participants, characteristics of clinical gastroenterology and gastrointestinal endoscopy practices, involvement of the physicians in the management of COVID-19, and overall impact of the pandemic on practice. find more All collected data were analyzed using descriptive statistics.

The 200 participants in this study had a median age of 50 (34-76) years. Modifications in clinical gastroenterology practice were frequently reported in the outpatient (95.5%) and inpatient (100%) settings. All participants reported changes in the gastrointestinal endoscopy practice patterns. Of the participants, 86.0% were working in high-risk zones, and several of them reported inadequate protective personal equipment (34.0%). The median overall impact score of the pandemic on practice was 9 (2-10).

Physicians practicing clinical gastroenterology and gastrointestinal endoscopy in Indonesia work in high-risk settings. Modifications in clinical gastroenterology and gastrointestinal endoscopy practices are prevalent during the COVID-19 pandemic.

Based on our experience, digital single-operator peroral cholangioscopy-guided electrohydraulic lithotripsy with endoscopic nasogallbladder drainage is a feasible minimally invasive approach for the management of high-grade Mirizzi syndrome.
Endoscopic resection (ER) for superficial non-ampullary duodenal epithelial tumors (SNADETs) is challenging. link3 Conventional endoscopic mucosal resection (CEMR) is also problematic due to the anatomical features of the duodenum. We compared the safety and efficacy of underwater endoscopic mucosal resection (UEMR) with those of CEMR through a retrospective analysis.

Altogether, 44 consecutive patients with 46 SNADETs underwent ER (18 CEMR cases and 28 UEMR cases) between January 2016 and October 2019. We investigated the proportions of en bloc resection, R0 resection, complications, resection time, and total procedure time and compared the outcomes of patients from the CEMR group with those of patients from the UEMR group.

The median tumor size was 8.0 mm (range, 2.0-20.0 mm). The UEMR group showed a higher proportion of en bloc resection (96.4% vs. 72.2%, p<0.05) and significantly lower median resection time and total procedure time (4 min vs. find more 9.5 min, p<0.05 and 13 min vs. 19 min, p<0.05; respectively) than the CEMR group. link3 No complications were observed. However, two patients treated with piecemeal resection in the CEMR group had residual tumors.

UEMR is a feasible therapeutic option for SNADETs. It can be recommended as a standard treatment.

MicroRNA-552 (miR-552) has been reported to correlate with the development and progression of various cancers, including colorectal cancer (CRC). This study aimed to investigate miR-552 expression in cancer tissue samples compared to normal mucosal tissue and its role as a diagnostic or prognostic marker in CRC patients.

Normal mucosal tissues and primary cancer tissues from 80 surgically resected CRC specimens were used. Quantitative real-time polymerase chain reaction was performed for miR-552 and U6 small nuclear RNA to analyze miR-552 expression and its clinicopathological significance. Immunohistochemistry for p53 and phosphatase and tension homolog (PTEN) was performed to evaluate their association with miR-552 expression.

miR-552 expression was significantly higher in primary cancer tissues compared to normal mucosal tissues (p<.001). The expression level of miR552 was inversely correlated with that of PTEN (p=.068) and p53 (p=.004). Survival analysis showed that high miR-552 expression was associated with worse prognosis but this was not statistically significant (p=.255). However, patients with CRC having high miR-552 expression and loss of PTEN expression had significantly worse prognosis than others (p=.029).

Our results suggest that high miR-552 expression might be a potential diagnostic biomarker for CRC, and its combined analysis with PTEN expression can possibly be used as a prognostic marker.

CD200 and BCL2 overexpression is independently associated with inferior survival in acute myeloid leukemia (AML), and these two factors are frequently co-expressed; however, no data are available on the role of concomitant aberrant CD200 and BCL2 expression on outcome of AML patients. We aimed to elucidate the prognostic role of CD200/BCL2 co-expression and its association with specific leukemia subsets.

We analyzed 242 adult AML patients uniformly treated with intensive chemotherapy, evaluating the impact of CD200 and BCL2 expression on complete remission (CR), disease-free survival, and overall survival (OS).

CD200 and BCL2 were expressed in 139 (57.4%) and 137 (56.6%) cases, respectively, with 92 patients (38%) displaying double positivity (DP), 58 (24%) displaying double negativity (DN), and 92 patients expressing only either CD200 (n=47) or BCL2 (n=45). CR was achieved in 71% of cases, being less frequent in DP patients (60%) compared to other groups (76%-81%, p<0.001). In the whole population 3-year OS was 44%, being lower in DP patients (28%) than in patients with single CD200 or BCL2 expression (47%) or DN cases (60%; p=0.004). Other factors associated with worse OS were advanced age, CD34 positivity, secondary AML, and high white blood cell count at diagnosis; combining these 4 factors with CD200/BCL2 DP, we identified 6 groups with significantly different rates of survival (3-year OS ranging from 90% to 0%).

Our data support a synergistic effect of CD200 and BCL2 in AML cells, conferring an enhanced survival capacity in a permissive microenvironment and resulting in worse prognosis.

Three-dimensional (3D) measurement of intracranial aneurysms is important in planning endovascular treatment, and 3D rotational angiography (RA) is effective in accurate measurement. The purpose of this study was to evaluate the feasibility of low dose 3D RA (5 seconds 0.10 μGy/frame) in measuring an intracranial aneurysm using an in vitro phantom.

We investigated an in vitro 3D phantom of an intracranial aneurysm with 10 acquisitions of 3D RA with a conventional dose (5 seconds 0.36 μGy/frame) and 10 acquisitions with a low-dose (5 seconds 0.10 μGy/frame). 3D size and neck diameters of the aneurysm were measured and compared between the 2 groups (conventional and low-dose) using noninferiority statistics.

The aneurysm measurements were well-correlated between the 2 readers, and noninferiority in the measurement of aneurysmal size of low-dose 3D RA was demonstrated, as the upper margin of the 1-sided 97.5% confidence interval did not cross the pre-defined noninferiority margin of 0.2 mm by the 2 readers.
