RESUMEN
A 65-year-old male complained of persistent melena for 6 days, and displayed anemia symptoms without hematemesis, vomiting, and abdominal distention. He was diagnosed as ruptured aneurysm of aortic sinus Valsalva, and had received coronary artery occlusion 1 month ago. After the operation, he was continually prescribed clopidogrel 75 mg once daily. The laboratory examination showed blood hemoglobin concentration was 60 g/L without other conspicuous abnormality. Unfortunately, neither esophagogastroduodenoscopy (EGD) nor colonoscopy found no obvious bleeding lesions. And abdominal computed tomography angiography (CTA) and enhanced computed tomography (CT) showed no obvious abnormal findings. Moreover, capsule endoscopy revealed small intestinal with mucosal erosion (Figure 1A). After discontinued clopidogrel, blood transfusion, and support therapy, his symptoms was resolved with negative fecal occult blood, continued clopidogrel 75 mg once daily, and uneventfully discharged 1 week later.

BACKGROUND: Esophageal-gastro varices bleeding (EGVB) is the most widely known cause of mortality in individuals with cirrhosis, with an occurrence rate of 5% to 15%. Among them, gastric varices bleeding (GVB) is less frequent than esophageal varices bleeding (EVB), but the former is a more critical illness and has a higher mortality rate. At present, endoscopic variceal histoacryl injection therapy (EVHT) is safe and effective, and it has been recommended by relevant guidelines as the primary method for the treatment of GVB. However, gastric varices after endoscopic treatment still have a high rate of early rebleeding, which is mainly related to complications of its treatment, such as bleeding from drained ulcers, rebleeding of varices etc. Therefore, preventing early postoperative rebleeding is very important to improve the quality of patient survival and outcomes. AIM: To assess the efficacy of aluminium phosphate gel (APG) combined with proton pump inhibitor (PPI) in preventing early rebleeding after EVHT in individuals with GVB. METHODS: Medical history of 196 individuals with GVB was obtained who were diagnosed using endoscopy and treated with EVHT in Shenzhen People's Hospital from January 2016 to December 2021. Based on the selection criteria, 101 patients were sorted into the PPI alone treatment group, and 95 patients were sorted into the PPI combined with the APG treatment group. The incidences of early rebleeding and corresponding complications within 6 wk after treatment were compared between both groups. Statistical methods were performed by two-sample t-test, Wilcoxon rank sum test and χ 2 test. RESULTS: No major variations were noted between the individuals of the two groups in terms of age, gender, Model for End-Stage Liver Disease score, coagulation function, serum albumin, hemoglobin, type of gastric varices, the dose of tissue glue injection and EV that needed to be treated simultaneously. The early rebleeding rate in PPI + APG group was 3.16% (3/95), which was much lower than that in the PPI group (12.87%, 13/101) (P = 0.013). Causes of early rebleeding: the incidence of gastric ulcer bleeding in the PPI + APG group was 2.11% (2/95), which was reduced in comparison to that in the PPI group (11.88%, 12/101) (P = 0.008); the incidence of venous bleeding in PPI + APG group and PPI group was 1. 05% (1/95) and 0.99% (1/101), respectively, and there was no significant difference between them (0.999). The early mortality rate was 0 in both groups within 6 wk after the operation, and the low mortality rate was related to the timely hospitalization and active treatment of all patients with rebleeding. The overall incidence of complications in the PPI + APG group was 12.63% (12/95), which was not significantly different from 13.86% (14/101) in the PPI group (P = 0.800). of abdominal pain in the PPI + APG group was 3.16% (3/95), which was lower than that in the PPI group (11.88%, 12/101) (P = 0.022). However, due to aluminum phosphate gel usage, the incidence of constipation in the PPI + APG group was 9.47% (9/95), which was higher than that in the PPI group (1.98%, 2/101) (P = 0.023), but the health of the patients could be improved by increasing drinking water or oral lactulose. No patients in either group developed spontaneous peritonitis after taking PPI, and none developed hepatic encephalopathy and ectopic embolism within 6 wk of EVHT treatment. CONCLUSION: PPI combined with APG can significantly reduce the incidence of early rebleeding and postoperative abdominal pain in cirrhotic patients with GVB after taking EVHT.
RESUMEN
Rectal neuroendocrine tumors (rNETs) measuring less than 10 mm in diameter are defined as small rNETs. Due to the low risk of distant invasion and metastasis, endoscopic treatments, including modified endoscopic mucosal resection, endoscopic submucosal dissection, and other transanal surgical procedures, are effective. This review article proposes a follow-up plan according to the size and histopathology of the tumor after operation.
RESUMEN
AIM: We compared endoscopic "calabash" ligation and resection (ECLR) and endoscopic submucosal excision (ESE) in treating endophytic gastric stromal tumors (GSTs) ≤15 mm in diameter originating from the muscularis propria. METHODS: We performed a retrospective study and included patients who visited our hospital for removal of small endophytic GSTs (diameter ≤ 15 mm) confirmed by postoperative pathological reports between February 2019 and December 2020. Patients were assigned to the study (received ECLR) or control (accepted ESE) groups, and their medical records were reviewed. Age, sex, GST size, resection outcomes, procedure measurements, lengths of hospital stays, medical expenses, intraoperative and postoperative complications, and follow-up outcomes were documented and compared between the two groups. Propensity score matching was used to avoid retrospective biases. RESULTS: A total of 277 patients were included in the analysis, with 135 in the study group and 142 in the control group. After propensity score matching, 119 cases in each group were finally included in the study. Compared to the control group, the study group had significantly shorter procedure durations and lengths of hospital stays, as well as reduced medical expenses. Compared to the control group, the study group also had significantly lower incidence rates of intraoperative stomach perforation, postoperative intraperitoneal infection, and postoperative electrocoagulation syndrome, as well as a lower intensity of postoperative pain. There were no significant differences in the other measurements between the two groups. CONCLUSION: ECLR is an effective and safe procedure for treating patients with endophytic GSTs ≤15 mm in diameter originating from the muscularis propria.

RESUMEN
Introduction and aim: duodenal subepithelial lesions (SELs) are increasingly detected during endoscopic examinations. However, no feasible and safe methods are available to remove duodenal SELs. The present study aimed to assess the feasibility and safety of endoscopic resection in combination with ligation (ER-L) for the removal of duodenal SELs.Patients and methods: a total of 101 patients with duodenal SELs underwent ER-L from February 2010 to February 2020. The primary outcomes were complete resection, en bloc resection and R0 resection. The secondary outcomes included procedure duration, bleeding, perforation and residual lesions. A total of 101 patients with 101 duodenal SELs (ranged from 8.4 mm to 20.2 mm in size) were included in the study.Results: most of the SELs (95.1 %) originated from the submucosal layer and were successfully removed using ER-L. The rates of complete resection, en bloc resection and R0 resection were 100 %, 96.0 % and 88.1 %, respectively. The median procedure duration was eight minutes. There were no severe complications, except for four patients who developed post-procedure bleeding (4.0 %) and recovered after conservative treatment. Furthermore, no residual lesions were detected during the follow-up period (median of 36 months). In fact, logistic regression analysis showed that the size of duodenal SELs was an independent factor for R0 resection during the ER-L procedure.Conclusion: in conclusion, ER-L is feasible and safe to remove duodenal SELs that originate from the submucosal layer and are less than 20 mm. However, the feasibility and safety of the ER-L should be further confirmed when removing the duodenal SELs that originate from the muscularis propria (MP) layer and are larger than 20 mm in diameter.

Background: Ascites is a common clinical finding caused by many different diseases, so we developed a technique termed single orifice percutaneous endoscopic surgery (SOPES) which can access peritoneal cavity through the contralateral McBurney's point or umbilicus to seek the underlying causes. In this study, we describe the initial clinical experience of SOPES and compare the application of two accesses. Methods: This is a retrospective study performed between 2007 and 2018. Patients with ascites of unknown origin who underwent these two kinds of SOPES were included. Main outcomes were measured by diagnostic accuracy, complication rate, procedure time, time till stitches removal, length of hospital stay, and hospital cost. Results: 148 patients successfully undergone SOPES via the contralateral McBurney's point (IM group, n = 70) or the umbilicus (UM group, n = 78). 63 patients in the IM group and 71 patients in the UM group reached clear diagnosis (90.0% vs. 91.0%, p = 0.831). The overall complication rate was 5.4%, while the UM group was higher than the IM group (10.3% vs. 0%, p = 0.017). All complications were resolved after medical treatment, and no mortality resulted from this procedure. The procedure time and the time until stitches removal in the UM group were longer than that in the IM group. There were no significant differences in length of hospital stay and hospital cost between the two groups. Conclusions: SOPES, which combines the strength of minimally invasive single orifice incision and flexible angles of examination and instrumentation, is a newly developed flexible endoscopic surgical modality that provides new important clinical valuable in evaluation of ascites of unknown origin. Moreover, SOPES via the contralateral McBurney's point was safer than the umbilicus approach.
RESUMEN
BACKGROUND: Esophageal stenosis is one of the main complications of endoscopic submucosal dissection (ESD) for the treatment of large-area superficial esophageal squamous cell carcinoma and precancerous lesions (≥ 3/4 of the lumen). Oral prednisone is useful to prevent esophageal stenosis, but the curative effect remains controversial. AIM: To share our experience of the precautions against esophageal stenosis after ESD to remove large superficial esophageal lesions. METHODS: Between June 2019 and March 2022, we enrolled patients with large superficial esophageal squamous cell carcinoma and high-grade intraepithelial neoplasia experienced who underwent ESD. Prednisone (50 mg/d) was administered orally on the second morning after ESD for 1 mo, and tapered gradually (5 mg/wk) for 13 wk. RESULTS: In total, 14 patients met the inclusion criteria. All patients received ESD without operation-related bleeding or perforation. There were 11 patients with ≥ 3/4 and < 7/8 of lumen mucosal defects and 1 patient with ≥ 7/8 of lumen mucosal defect and 2 patients with the entire circumferential mucosal defects due to ESD. The longitudinal extension of the esophageal mucosal defect was < 50 mm in 3 patients and ≥ 50 mm in 11 patients. The esophageal stenosis rate after ESD was 0% (0/14). One patient developed esophageal candida infection on the 30th d after ESD, and completely recovered after 7 d of administration of oral fluconazole 100 mg/d. No other adverse events of oral steroids were found. CONCLUSION: Oral prednisone (50 mg/d) and prolonged prednisone usage time may effectively prevent esophageal stricture after ESD without increasing the incidence of glucocorticoid-related adverse events. However, further investigation of larger samples is required to warrant feasibility and safety.
RESUMEN
BACKGROUND: A disposable upper gastrointestinal endoscope can effectively decrease infectious outbreaks associated with endoscope reuse. In the present study, we aimed to evaluate the feasibility and safety of a disposable endoscope for upper gastrointestinal examination. METHODS: In a prospective, randomized trial, 144 upper endoscopic procedures were allocated to either the disposable endoscope group or the conventional endoscope group. The primary outcomes were rates of excellent and good image qualities and maneuverability satisfaction. The second outcome included procedure duration, endoscopic diagnosis, and adverse events. RESULTS: A total of 144 subjects were enrolled in the present analysis and prospectively randomized to 2 study groups. Finally, 70 and 69 subjects were enrolled in the novel disposable endoscope group and the conventional endoscope group, respectively, due to the schedule cancellation of 5 subjects. The baseline characteristics of the patients were similar in both groups. The excellent and good image quality rates and maneuverability satisfaction of the novel disposable endoscope were not inferior to the conventional endoscope (p = 0.99 and p = 0.99, respectively). Moreover, no significant between-group difference was observed in the endoscopic results and adverse events (p = 0.30 and p = 1, respectively). However, the procedure duration in the novel disposable endoscope was longer compared with the conventional endoscope (8.40 ± 4.28 min vs. 5.12 ± 2.65 min, p < 0.001). CONCLUSIONS: The novel disposable endoscope was as safe, effective, and maneuverable as a conventional endoscope. However, the novel disposable endoscope was associated with a longer procedure duration.

Background and Aims: Simethicone (SIM), as an antifoaming agent, has been shown to improve bowel preparation during colonoscopy. However, the optimal timing of SIM addition remained undetermined. We aimed to investigate the optimal timing of SIM addition to polyethylene glycol (PEG) to improve bowel preparation. Methods: Eligible patients were randomly assigned to two groups: the SIM evening group (SIM addition to PEG in the evening of the day prior to colonoscopy) and the SIM morning group (SIM addition to PEG in the morning of colonoscopy). The primary outcome was Bubble Scale (BS). The secondary outcomes were Boston Bowel Preparation Scale (BBPS) and adenoma detection rate (ADR). Results: A total of 419 patients were enrolled in this study. The baseline characteristics of the patients were similar in both groups. No significant differences were observed in terms of BS (8.76 ± 0.90 vs. 8.65 ± 1.16, P = 0.81), ADR (34.1% vs. 30.8%, P = 0.47), Boston Bowel Preparation Scale (BBPS) (8.59 ± 0.94 vs. 8.45 ± 1.00, P = 0.15), and withdrawal time (8.22 ± 2.04 vs. 8.01 ± 2.51, P = 0.094) between the two groups. Moreover, safety and compliance were similar in both groups. However, the SIM evening group was associated with shorter cecal intubation time (3.80 ± 1.81 vs. 4.42 ± 2.03, P < 0.001), higher BS (2.95 ± 0.26 vs. 2.88 ± 0.38, P = 0.04) in the right colon, and diminutive ADR (62.5% vs. 38.6%, P = 0.022) in the right colon, when compared to the SIM evening group. Conclusions: The SIM addition to PEG in the evening of the day prior to colonoscopy can shorten cecal intubation time and improve BS scores and diminutive ADR of the right colon compared with the SIM addition to PEG in the morning of colonoscopy in bowel preparation.

BACKGROUND: Ulcerative colitis (UC) is a chronic inflammatory disease with increasing prevalence worldwide. Barrier defect in intestinal epithelial cells (IECs) is one of the main pathogeneses in UC. Pyroptosis is a programmed lytic cell death and is triggered by inflammatory caspases, while little is known about its role in UC. METHODS: Differentially expressed genes (DEGs) were identified by comparing UC patients with healthy controls from the GEO datasets. The candidate genes involved in pyroptosis were obtained, and the underlying molecular mechanism in the progression of UC was explored in vivo and in vitro. RESULTS: Pleckstrin homology domain leucine-rich repeat protein phosphatase 2 (PHLPP2), a protein phosphatase, was downregulated and involved in regulating inflammation-induced IEC pyroptosis by modulating the NF-κB signaling in UC through bioinformatics analysis. Moreover, we demonstrated that PHLPP2 was downregulated in UC patients and UC mice. Besides, we found that PHLPP2 depletion activated the NF-κB signaling and increased the expressions of caspase-1 P20, Gasdermin N, IL-18, and IL-1ß contributing to IEC pyroptosis and inflammation in UC mice. Furthermore, we found that PHLPP2-/- mice developed hypersensitivity to dextran sulfate sodium (DSS) treatment toward colitis showing activated NF-κB signaling and dramatically induced expressions of caspase-1 P20, Gasdermin N, IL-18, and IL-1ß. Mechanically, this inflammation-induced downregulation of PHLPP2 was alleviated by an NF-κB signaling inhibitor in intestinal organoids of PHLPP2-/- mice and fetal colonic cells. CONCLUSIONS: PHLPP2 downexpression activated the NF-κB signaling and promoted the IEC pyroptosis, leading to UC progression. Therefore, PHLPP2 might be an attractive candidate therapeutic target for UC.

Background: Submucosal tunneling endoscopic resection (STER) has effectively removed esophageal submucosal tumors (SMTs) originating from the muscularis propria (MP) layer. However, clinical failure and adverse events of STER remain concerned. In this study, we described a mark-guided STER (markings before creating entry point) and evaluated its feasibility and safety for esophageal SMTs originating from MP. Methods: Patients receiving the mark-guided STER from October 2017 to July 2020 were included and followed up (ranged from 3 to 30 months). The primary outcomes included complete resection, en bloc resection, and R0 resection rates. The secondary outcomes included procedure duration, main complication, and residual lesions. Results: A total of 242 patients with 242 SMTs (median diameter of 22 mm, ranging from 7 mm to 40 mm) received the mark-guided STER. The median procedure duration was 55 min (ranging from 35 min to 115 min). The complete resection, en bloc resection, and R0 resection rates were 100%, 98.3%, and 97.5%, respectively. The adverse event rate was 4.5%. However, there was no severe complication. No residual SMTs were detected during the follow-up period. Logistic regression demonstrated that the SMT size and procedure duration were independent factors associated with en bloc resection (P=0.02 and P=0.04, respectively). Moreover, logistic regression demonstrated that the SMT size was an independent risk factor for main complications (P=0.02). Conclusion: Mark-guided STER was feasible and safe to remove esophageal SMTs â¦40 mm. However, it is necessary to further verify the feasibility and safety for the esophageal SMTs >40 mm.

Gastrointestinal stromal tumors can occur in any part of the gastrointestinal tract, but gastric stromal tumors (GSTs) are the most common. All GSTs have the potential to become malignant, and these can be divided into four different grades by risk from low to high: Very low risk, low risk, medium risk, and high risk. Current guidelines all recommend early complete excision of GSTs larger than 2 cm in diameter. However, it is not clear whether small GSTs (sGSTs, i.e., those smaller than 2 cm in diameter) should be treated as early as possible. The National Comprehensive Cancer Network recommends that endoscopic ultrasonography-guided (EUS-guided) fine-needle aspiration biopsy and imaging (computed tomography or magnetic-resonance imaging) be used to assess cancer risk for sGSTs detected by gastroscopy to determine treatment. When EUS indicates a higher risk of tumor, surgical resection is recommended. There are some questions on whether sGSTs also require early treatment. Many studies have shown that endoscopic treatment of GSTs with diameters of 2-5 cm is very effective. We here address whether endoscopic therapy is also suitable for sGSTs. In this paper, we try to explain three questions: (1) Does sGST require treatment? (2) Is digestive endoscopy a safe and effective means of treating sGST? and (3) When sGSTs are at different sites and depths, which endoscopic treatment method is more suitable?
RESUMEN
BACKGROUND: Liver cirrhosis is the main cause of portal hypertension. The leading cause of death in patients with liver cirrhosis is its most common complication, esophageal variceal bleeding (EVB). Endoscopic variceal ligation (EVL) is recommended by many guidelines to treat EVB and prevent rebleeding; however, esophageal ulcers occur after treatment. Delayed healing of ulcers and unhealed ulcers lead to high rebleeding and mortality rates. Thus, the prevention of early postoperative rebleeding is of great significance in improving the quality of life and prognosis of patients. AIM: To evaluate the efficacy of aluminum phosphate gel (APG) plus a proton pump inhibitor (PPI) in the prevention of early rebleeding after EVL in patients with EVB. METHODS: The medical records of 792 patients who were diagnosed with EVB and in whom bleeding was successfully stopped by EVL at Shenzhen People's Hospital, Guangdong Province, China from January 2015 to December 2020 were collected. According to the study inclusion and exclusion criteria, 401 cases were included in a PPI-monotherapy group (PPI group), and 377 cases were included in a PPI and APG combination therapy (PPI + APG) group. We compared the incidence rates of early rebleeding and other complications within 6 wk after treatment between the two groups. The two-sample t-test, Wilcoxon rank-sum test, and chi-squared test were adopted for statistical analyses. RESULTS: No significant differences in age, sex, model for end-stage liver disease score, coagulation function, serum albumin level, or hemoglobin level were found between the two groups. The incidence of early rebleeding in the PPI + APG group (9/337; 2.39%) was significantly lower than that in the PPI group (30/401; 7.48%) (P = 0.001). Causes of early rebleeding in the PPI group were esophageal ulcer (3.99%, 16/401) and esophageal varices (3.49%, 14/401), while those in the PPI + APG group were also esophageal ulcers (5/377; 1.33%) and esophageal varices (4/377; 1.06%); such causes were significantly less frequent in the PPI + APG group than in the PPI group (P = 0.022 and 0.024, respectively). The early mortality rate within 6 wk in both groups was 0%, which was correlated with the timely rehospitalization of all patients with rebleeding and the conduct of emergency endoscopic therapy. The incidence of adverse events other than early bleeding in the PPI + APG group (28/377; 7.43%) was significantly lower than that in the PPI group (63/401; 15.71%) (P < 0.001). The incidence of chest pain in the PPI + APG group (9/377; 2.39%) was significantly lower than that in the PPI group (56/401; 13.97%) (P < 0.001). The incidence of constipation in the PPI + APG group (16/377; 4.24%) was significantly higher than that in the PPI group (3/401; 0.75%) (P = 0.002) but constipation was relieved after patients drank more water or took lactulose. In the PPI and PPI + APG groups, the incidence rates of spontaneous peritonitis within 6 wk after discharge were 0.50% (2/401) and 0.53% (2/377), respectively, and those of hepatic encephalopathy were 0.50% (2/401) and 0.27% (1/377), respectively, presenting no significant difference (P > 0.999). CONCLUSION: PPI + APG combination therapy significantly reduces the incidence of early rebleeding and chest pain in patients with EVB after EVL.
