ABSTRACT

Background/Aims@#In patients with acute nonvariceal upper gastrointestinal bleeding (ANVUGIB), the optimal timing of endoscopy is still a matter of dispute. We conducted a systematic review and meta-analysis to determine the clinical benefit of early endoscopy. @*Methods@#A literature search of the MEDLINE, Embase, and Cochrane databases was conducted to identify publications from inception to March 1, 2022. Eligible studies included observational cohort studies and randomized controlled trials that reported clinical outcomes of endoscopy in patients with ANVUGIB. ANVUGIB patients who underwent endoscopy within 24 hours of admission were considered to have had an early endoscopy. The primary outcome was the mortality rate in ANVUGIB patients who had early or nonearly endoscopy. @*Results@#The final analysis included five randomized controlled studies (RCTs) and 20 observational studies from the 1,206 identified articles. The mortality rate was not significantly reduced among patients who received endoscopy performed within 24 hours, whether in cohort studies nor in RCTs. For subgroup analysis, a higher mortality rate was found only among patients who received very early endoscopy within 12 hours (odds ratio, 1.66; p<0.001, I 2 =0) in cohort studies. No significant difference in mortality rates was found among patients at high risk of bleeding who received early versus nonearly endoscopy. @*Conclusions@#Early endoscopy within 24 hours does not appear to significantly reduce the mortality rates of patients with ANVUGIB. Further well-designed studies are warranted to address if very early endoscopy within 12 hours can provide a clinical benefit for patients at high risk of bleeding.

ABSTRACT

Objective:To analyze the clinicopathological features of de novo early colorectal cancer and to evaluate the efficacy of endoscopic treatment.Methods:Patients with de novo early colorectal cancer who underwent endoscopic resection in Beijing Friendship Hospital, Capital Medical University from June 2020 to May 2022 were enrolled. The baseline data, endoscopic manifestations, treatment methods, postoperative pathological results and prognosis of the patients were collected retrospectively.Results:A total of 33 patients with de novo early colorectal cancer were enrolled with the age of 62.67 ± 8.62 years, and the male to female ratio was 7.25∶1. The long diameter of lesions was 0.96 ± 0.36 cm. The lesion morphology was mainly superficial phenotype (type 0-Ⅱ), accounting for 72.7% (24/33). Endoscopic submucosal dissection (ESD) was performed in 29 cases and endoscopic mucosal resection (EMR) was performed in 4 cases. Postoperative pathology showed that 11 cases (33.3%) were well differentiated tubular adenocarcinoma, of which the superficial submucosal layer was invaded in 2 cases. Twenty cases (60.6%) were moderately differentiated tubular adenocarcinoma, of which the superficial submucosa layer was invaded in 5 cases and the deep submucosa layer in 15 cases. Two cases (6.1%) were moderately-poorly differentiated tubular adenocarcinoma, where the deep submucosa layer was invaded in both. There was significant correlation between the depth of invasion and the degree of differentiation ( P<0.001), and moderately and moderately-poorly differentiated lesions were more likely to invade the deep submucosa layer. The en bloc resection rate was 100.0% (33/33), the complete resection rate was 97.0% (32/33), and the curative resection rate was 42.4% (14/33). Among the 19 patients who did not achieve curative resection, 13 patients received supplementary surgical treatment. No tumor residue or lymph node metastasis was found in the postoperative pathology. All patients were followed up for 3-25 months, and no signs of local recurrence or metastasis were found. Conclusion:Most de novo early colorectal cancers are superficial phenotype under endoscopy. The pathology is mainly moderately differentiated tubular adenocarcinoma. Endoscopic resection of de novo early colorectal cancer shows encouraging short-term efficacy.

ABSTRACT

Objective:To investigate the clinical features, characteristics under white-light endoscopy and endoscopic ultrasonography, and treatment strategies of gastritis cystica profunda (GCP) accompanied with or without neoplastic lesions.Methods:Clinical data of 35 patients, who were pathologically diagnosed as having GCP after endoscopic or surgical resection in Beijing Friendship Hospital, Capital Medical University from January 2015 to February 2021, were retrospectively collected, including 27 patients with neoplastic lesions. The demographic information, clinical manifestations, endoscopic features, treatment methods, and pathological results of GCP were summarized.Results:Thirty-five patients with GCP were 68.26±8.08 years old, and mostly male (80.00%, 28/35). The most common symptom was upper abdominal pain, accounting for 31.43% (11/35), and 25.71% (9/35) had no symptoms. Other symptoms included acid reflux, heartburn, abdominal distension, anemia, and choking sensation after eating. The most common site of GCP was cardia (51.43%, 18/35), and the main endoscopic manifestations of GCP were flat mucosal lesions (68.57%, 24/35), mainly 0-Ⅱa and 0-Ⅱa+Ⅱc type lesions, accounting for 66.67% (16/24). The second common endoscopic manifestation was polypoid eminence (20.00%, 7/35). Endoscopic ultrasonography was performed in 15 patients, with main manifestations of uniform hypoechoic with or without cystic echo (73.33%, 11/15). Among the GCP cases, 33 patients received endoscopic resection, and 2 received surgical treatment. The treatment processes were all successfully completed, and en-bloc resection was accomplished for all lesions receiving endoscopy, with the mean endoscopic operation time of 86.13 min. One patient suffered postoperative delayed bleeding after ESD which was stopped by endoscopic hemostasis. Final pathological results showed that the proportion of GCP complicated with neoplastic lesions was 77.14% (27/35), 68.57% (24/35) with early gastric cancer or precursor. Twenty-three cases achieved R0 resection. One case showed positive basal resection margin and vascular invasion, and recurrence happened in situ at the 5th month of follow-up, surgical resection was then performed. The endoscopic complete resection rate was 95.83% (23/24).Conclusion:GCP usually occurs in middle-aged and elderly male, often located in cardia, manifested mainly as flat mucosal lesions and polypoid changes. Endoscopic ultrasonography shows a high diagnostic value for GCP, and endoscopic treatment is safe and effective minimally invasive treatment for GCP.

ABSTRACT

Objective:To compare the efficacy of domestic and imported hemostatic clips in preventing delayed post-polypectomy bleeding (DPPB) after endoscopic resection of colorectal polyps ≥ 10 mm.Methods:Clinical data of 789 patients who underwent endoscopic resection of colorectal polyps (polyp diameter ≥10 mm) in Beijing Friendship Hospital, Capital Medical University from January 2018 to December 2019 were collected. The patients were divided into DPPB group ( n=15) and non-DPPB group ( n=774). Univariate and multivariate logistic regression models were used to analyze the influential factors for DPPB. The patients using one type of hemostatic clip were divided into the domestic hemostatic clip group ( n=499) and the imported hemostatic clip group ( n=208). The efficacy of hemostatic clips in preventing DPPB in the two groups was compared. Results:Among the 789 patients undergoing endoscopic resection of colorectal polyps, 1.9% (15/789) suffered from DPPB. Multivariate logistic regression analysis showed that pedunculated polyp was an independent risk factor for DPPB ( OR=6.621, 95% CI: 2.278-19.241, P=0.001), and closure of mucosal defect was an independent protective factor for DPPB ( OR=0.169,95% CI: 0.050-0.570, P=0.004). Regardless of physician experience, there was no significant difference between the domestic and imported hemostatic clip group in preventing DPPB after endoscopic resection of colorectal polyps ≥10 mm [experienced physicians: 1.8% (7/385) VS 0.6% (1/175), χ2=1.314, P=0.445; common physicians: 2.6% (3/114) VS 3.0% (1/33), χ2=0.010, P>0.999]. The domestic hemostatic clip group paid for less medical expenses than the imported hemostatic clip group (experienced physicians: 1 433.51±889.02 yuan VS 3 033.97±1 686.87 yuan, t<0.001 , P<0.001; common physicians: 1 181.58±815.29 yuan VS 3 303.46±1 690.43 yuan, t<0.001 ,P<0.001). Conclusion:Pedunculated polyp is an independent risk factor for DPPB after endoscopic resection of colorectal polyp larger than 10 mm, and clipping can significantly reduce the risk for DPPB. There is no significant difference in the prevention of DPPB between domestic and imported clips, but domestic clips compared with imported clips yield less medical burden, which are suitable for promotion to primary hospitals and major clinical centers.

ABSTRACT

Objective:To evaluate the application of three-dimensional (3D) imaging device to colonoscopy.Methods:A total of 60 patients who underwent painless colonoscopy in Beijing Friendship Hospital, Capital Medical University from November to December, 2019 were enrolled and divided into 2 groups according to random code. Each patient underwent colonoscopy twice, while 2D colonoscopy was used for cecal intubation. Thirty patients were assigned to the experimental group (primary withdrawal used 3D colonoscopy, and secondary withdrawal used 2D colonoscopy), and 30 others to the control group (primary withdrawal used 2D colonoscopy, and secondary withdrawal used 3D colonoscopy). The detection of polyps, the withdrawal time, operating experience, image quality and complication were evaluated in the two groups.Results:The polyp detection rate at the first colonoscopy in the experimental group was 77.3% (17/22), which was higher than 43.5% (10/23) in the control group ( χ2=5.351, P=0.021). Ten operators in the experimental group had dizziness, while the operators in the control group had no dizziness ( P=0.001). There were no significant differences between the two groups in the polyp diameter [0.50 (0.70) cm VS 0.30 (0.20) cm, U=57.000, P=0.170], withdrawal time (4.6±1.5 min VS 5.2±1.9 min, t=-1.189, P=0.239) or image quality (27 cases with 3 points in the identification of lesion nature, and 28 cases with 3 points in the identification of duct both in the two groups, P=1.000) at the first colonoscopy. No complication occurred in either group. Conclusion:Application of 3D imaging device is feasible for colonoscopic polyp detection, and it can be used in clinical practice.

ABSTRACT

Objective:To evaluate the effects of hemoclips on preventing delayed bleeding for early gastric cancer (EGC) after endoscopic submucosal dissection (ESD).Methods:Clinical data of 459 patients who underwent ESD for EGC in Beijing Friendship Hospital from June 2013 to August 2020 were collected retrospectively. Patients were divided into group A (hemoclip group, n=162) and group B (non-hemoclip group, n=297) according to whether preventive hemostatic clip treatment was performed after resection. Delayed bleeding within 2 weeks after ESD was observed. Univariate analysis and subgroup analysis were conducted for the delayed bleeding incidence and clinicopathological features. Results:Delayed bleeding incidences of group A and group B were 3.1% (5/162) and 8.1% (24/297) with significant difference between the two groups ( χ2=4.418, P=0.036). Subgroup analysis showed that there were significant differences in the delayed bleeding incidence between the two groups when the diameter of the tumor >20 mm [3.5% (2/57) VS 15.3% (13/85), χ2=5.016, P=0.025], the tumor located in the lower part of the stomach [1.0% (1/97) VS 10.4% (20/192), χ2=8.425, P=0.004], and the depth of tumor invasion was M/SM1 [3.2% (5/157) VS 8.1% (23/285), χ2=4.072, P=0.044]. There were no significant differences in the delayed bleeding incidence between group A and group B when the diameter of the tumor ≤20 mm, the tumor located in the upper/medial part of the stomach and the depth of tumor invasion was SM2 ( P>0.05). Conclusion:Hemoclips can prevent delayed bleeding after ESD for EGC, which is mainly observed in a tumor of diameter >20 mm, located in the lower part of the stomach and M/SM1 tumor invasion. It has little effect on the prevention when the tumor diameter ≤20 mm and located in the upper/medial part of the stomach.

ABSTRACT

Objective:To evaluate the clinical efficacy of endoscopic treatment for early nonampullary duodenal cancer.Methods:Data of patients with early nonampullary duodenal cancer, who underwent endoscopic treatment from January 2015 to January 2021 at Beijing Friendship Hospital were retrospectively analyzed. Baseline data, endoscopic treatment methods, wound closure, pathology, the occurrence and outcome of complications of patients were studied.Results:A total of 47 patients who successfully went through endoscopic treatment were enrolled. Seventeen cases received endoscopic mucosal resection (EMR), 5 cases received endoscopic submucosal dissection (ESD), and 7 cases received ESD+EMR (hybrid ESD). Six cases were converted to hybrid ESD due to difficulty in ESD. Four cases received full-thickness resection with over-the-scope clip system (OTSC), and 8 cases received endoscopic piecemeal mucosal resection (EPMR). Among the 47 cases of early cancer, the en bloc resection rate was 83.0% (39/47), and the complete resection rate was 85.1% (40/47). Four patients (8.5%) had perforation which occurred at the duodenal descending part during the perioperative period, among whom, 2 patients (4.3%) recovered after endoscopic treatment, 2 others (4.3%) recovered after surgical intervention. There were no complications such as postoperative bleeding or infection during the perioperative period.Conclusion:Endoscopic treatment for early nonampullary duodenal cancer is safe and effective. A specific treatment plan can be selected according to the location, size and specific conditions of the lesion. For the operation of the descending part, it is necessary to be more vigilant to against the occurrence of perforation complications.

ABSTRACT

Objective:To evaluate the effects of single spay of L-menthol (NPO-11) on suppressing gastric peristalsis during upper gastrointestinal endoscopy and the influencing factor.Methods:This study was a multicenter, randomized, double-blind, placebo-parallel controlled study. The eligible patients were randomly divided into two groups by randomized blocks. Patients received local spray of either NPO-11 (160 mg L-menthol) or placebo 20 mL during upper gastrointestinal endoscopy. The gastric peristalsis was recorded and evaluated before, 2 minutes after and at the end of endoscopy. The complexity of the procedure was evaluated by the researchers. The influencing factors for antiperistaltic effect of NPO-11 were analyzed.Results:A total of 220 patients were enrolled from five research centers. There were 109 cases in the NPO-11 group and 111 cases in the placebo group. The baseline data of the two groups were similar and comparable. The proportion of patients with grade 1 peristalsis at 2 minutes after the treatment and at the end of endoscopy was significantly higher in the NPO-11 group than that in the placebo group [40.37% (44/109) VS 16.22% (18/111), χ2=15.93, P<0.001]. Compared with the placebo group, the proportions of weak peristalsis (grade 1 and 2) were higher in the NPO-11 group at 2 minutes after the treatment [67.89% (74/109) VS 46.85% (52/111)] and at the end of endoscopy [79.82% (87/109) VS 48.65% (54/111)]. Subgroup analysis showed that the inhibitory effect of NPO-11 on gastric peristalsis was more significant in Helicobacter pylori antibody positive group. Conclusion:Local spray of NPO-11 can effectively inhibit gastric peristalsis during upper gastrointestinal endoscopy, and its effect is more significant in Helicobacter pylori antibody positive group. It could be recommended for no obvious adverse reactions , its safety, and the convenient procedure.

ABSTRACT

Objective:To compare the efficacy of oral sulfate solution (OSS) and polyethylene glycol (PEG) electrolyte powder for colonoscopy bowel preparation.Methods:A total of 283 randomized patients from 9 centers in China taking OSS ( n=143) or PEG ( n=140) using two-day split bowel preparation regimen received colonoscopy and assessment. The primary index was the bowel preparation success rate [global Boston bowel preparation scale (BBPS)≥ 6 by independent assessment center]. Secondary indices included BBPS global and segmental scores, investigator satisfaction (5-point Likert scale) with the quality of bowel preparation, patient satisfaction assessed by questionnaires, and patient tolerance assessed by Sharma scale. Compliance and safety were compared between the two groups. Results:The bowel preparation success rates were 100.0% for OSS and 99.3% for PEG [adjusted difference 0.7% (95% CI: -5.3% - 6.7%), P<0.001 for non-inferiority]. The BBPS global score in OSS group was significantly higher than that in PEG group (8.1 VS 7.7, P<0.001). The segment BBPS scores were also higher in OSS group than those in PEG group for all 3 segments (right colon: 2.4 VS 2.3, P=0.002; transverse colon: 2.8 VS 2.7, P=0.018; left colon: 2.8 VS 2.7, P=0.007). Investigator Likert score in the OSS group was significantly higher than that in the PEG group (2.6 VS 2.3, P<0.001). There was no significant difference in compliance between OSS and PEG, except for the second dose (90.9% VS 82.6%, P=0.039). There was no significant difference in patient satisfaction, Sharma score or proportion of patients with tolerance-related symptoms between the two groups. Safety was comparable between the two groups, and all adverse events were mild to moderate. Conclusion:OSS has comparable efficacy with PEG, with higher BBPS scores in all segments, better investigator satisfaction, better compliance in split dose, and comparable patient tolerance and safety.

ABSTRACT

Objective:To evaluate the clinical efficacy of endoscopy for early cancer of duodenal papilla.Methods:A retrospective analysis was performed on data collected from 23 consecutive patients with early cancer of duodenal papilla, who underwent endoscopic treatment from January 2015 to January 2021 in Beijing Friendship Hospital. Baseline data, endoscopic and pathological data, occurrence and outcome of complications were studied.Results:Twenty-three patients successfully received endoscopic treatment. The maximal diameter of lesions evaluated under endoscopy was 1.90±0.83 cm. Among the 23 cases, 20 underwent endoscopic mucosal resection and 3 underwent endoscopic piecemeal mucosal resection. Delayed bleeding occurred in 5 cases (21.7%), 3 patients (13.0%) developed postoperative hyperamylasemia, 6 patients (26.1%) developed mild acute pancreatitis, and 1 patient (4.3%) had pancreatic duct stent displacement after the operation, which improved after medical or endoscopic treatment. No perforation occurred during the perioperative period. In terms of final pathology, the en bloc resection rate was 82.6% (19/23), and the complete resection rate was 78.3% (18/23). Preoperative endoscopic ultrasonography showed that 19 lesions were confined to the mucosal layer, which were all demonstrated by postoperative pathology. Four other cases were suspected to be involved in the submucosa or the end of the pancreaticobiliary duct under endoscopic ultrasonography, two of which were confined to the mucosal layer, and the other 2 cases involved the submucosal layer, so additional surgery was performed. A total of 18 patients were followed up, among whom 14 achieved complete resection of postoperative pathology, and 2 patients (14.3%, 2/14) were found to have recurrence at 12 and 51 months respectively after the treatment and did not relapse after surgical treatment and endoscopic treatment respectively. Among 4 other patients of follow-up whose pathology did not achieve complete resection, 1 had no recurrence, and the other 3 received additional surgical treatment without recurrence.Conclusion:Endoscopic treatment for early cancer of duodenal papilla is safe and effective. It is necessary to improve preoperative evaluation, stay alert to perioperative complications, and pay attention to regular postoperative endoscopic follow-up.

ABSTRACT

Objective:To evaluate the efficacy and safety of rubber band traction-assisted endoscopic submucosal dissection (ESD).Methods:A total of 49 patients with rectal endocrine tumor who underwent ESD at Beijing Friendship Hospital Affiliated to Capital Medical University from January 2016 to December 2019 were reviewed. Thirty-two patients who underwent traditional ESD from January 2016 to May 2018 were assigned to the non-traction group. Seventeen patients who underwent the operation with a rubber band as auxiliary traction from June 2018 to December 2019 were assigned to the traction group. Basic information, ESD procedure time, complications were compared between the two groups.Results:There were no significant differences in age, gender or lesion size between the traction group and the non-traction group ( P>0.05). The ESD operation time of the traction group was significantly shorter than that of the non-traction group (13.76±5.71 min VS 22.99±10.32 min, t=-3.408, P=0.001). There were no postoperative complications in the traction group, but 3 cases of perforation occurred in the non-traction group. There was no significant difference in the incidence of perforation between the two groups ( P=0.542). Conclusion:Rubber band traction can safely improve the efficiency of ESD.

ABSTRACT

Objective:To investigate the clinicopathological features of missed synchronous multiple early gastric cancer (SMEGC).Methods:Clinical and pathological data of 10 missed SMEGC patients in Beijing Friendship Hospital collected from January 2015 to December 2019 were reviewed for the clinicopathological and endoscopic features.Results:Ten missed SMEGC patients were all over 60 years old, and 6 of them were males. Six patients had family history of tumor and 6 had comorbidity (hypertension, diabetes, dyslipidemia, cardiovascular or cerebrovascular diseases). In terms of endoscopic and pathological manifestations, missed lesions of 6 cases were not smaller than the initial lesions, and more than half of the missed lesions had the same vertical location in the stomach (6/10), infiltration depth (8/10), histological classification (9/10), atrophic (8/10) and intestinal metaplasia (8/10) as the initial lesions.Conclusion:Physicians should be aware of the possibility of missed lesions during the first endoscopic treatment and the follow-up, especially at the same vertical location of the initial lesions in elderly males with family history of tumor and comorbidity.

ABSTRACT

To investigate the clinical and endoscopic characteristics and endoscopic treatment efficacy of cap polyposis, data of 14 patients (56 polyps) who were histologically diagnosed as having cap polyposis after endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) in Beijing Friendship Hospital from June 2017 to February 2021 was retrospectively analyzed. Of the 14 patients, 8 were males and 6 were females. The age ranged from 14 to 74 years, including 7 cases of <60 years old and 7 cases of ≥60 years old. 7 patients (50.0%) had clinical manifestations. Four cases had multiple polyps and 10 cases (71.4%) had single polyps. There were 42 polyps (75.0%) located in the rectum, 13 (23.2%) in the sigmoid colon and 1 in the transverse colon. According to the classification of Yamada, 44 polyps (78.6%) were type Ⅰ, 3 polyps were type Ⅱ, 5 polyps were type Ⅲ and 4 polyps were type Ⅳ. Under endoscopy, there were 41 polyps (73.2%) with obvious white cap-like coverings on the surface and 23 polyps with obvious hyperemia and redness on the mucosa, 8 of which were both visible. Two cases were treated with ESD and 12 cases were treated with EMR, all of which were completely excised. No bleeding, perforation, infection or other complications occurred during and after operation. The clinical symptoms of 7 patients were relieved. During the follow-up period, 11 cases (78.6%) completed colonoscopy, and no polyp recurrence was found. In conclusion, there is no gender or age difference in patients of cap polyposis. It is usually single and located in the rectum and sigmoid colon with Yamada type Ⅰ. The surface of lesions is mostly covered with white cap. Patients may have no obvious clinical symptoms. Treatment of ESD and EMR is safe and effective for cap polyposis.

ABSTRACT

Objective:To evaluate the efficacy and safety of SPOT (GI Supply, USA), a new carbon-based permanent marker approved by the Food and Drug Administration (FDA), in the endoscopic marking for gastrointestinal lesions.Methods:A total of 115 patients with gastrointestinal lesions who underwent endoscopic treatment or surgery in Beijing Friendship Hospital or Beijing Chao-Yang Hospital from April 2019 to November 2019 were enrolled in the study. SPOT was used to mark the lesions, and marking points were found during endoscopic treatment or surgery to calculate the effective marking rate by single-group target value method. Adverse events after marking were recorded, and the changes of blood routine test, liver and kidney functions before and after marking were compared.Results:The effective rate of endoscopic marking with SPOT was 99.13% (114/115). The longest marking time was 57 days. There was no puncture of intestinal wall or injection into abdominal cavity during the marking process. One patient developed mild fever after marking. The incidence of adverse events was 23.48% (27/115), which were all unrelated to the test equipment. There was no significant difference in blood routine tests or liver and kidney functions before and after marking ( P>0.05). Conclusion:SPOT produced by GI Supply can effectively mark gastrointestinal lesions without serious adverse events, which meets the requirements of clinical use.

ABSTRACT

Clinical data of 5 patients with pancreatic and liver lesions who underwent endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in the Department of Gastroenterology of Beijing Friendship Hospital from February to May 2020 were analyzed retrospectively. Pancreatic lesions were located in the head of pancreas in 3 cases, the neck of pancreas in 1 case and the body of pancreas in 1 case, with the maximum diameter of 3.2-4.6 cm. The histological and cytologic results of pancreas were all positive in 5 patients after 2-4 needles of aspiration. Three patients had single lesion in left lobe of liver, 1 had multiple lesions in left lobe of liver, and 1 had multiple lesions in left and right lobe of liver. The maximum diameter of liver lesions were 0.4-1.2 cm. After 1-3 needles of aspiration, the histological and (or) cytologic results of liver were positive in 4 of 5 patients, only 1 patient's cytologic result was negative. No associated complications were recorded. EUS-FNA for pancreatic and liver lesions is safe and effective.

ABSTRACT

To investigate the risk factors for early colorectal cancer in patients with dyslipidemia and the possible role of statins, data of 266 patients with colorectal mass and dyslipidemia who received endoscopic treatment in Beijing Friendship Hospital from February 2018 to February 2021 were collected. The patients were divided into the colorectal adenoma group ( n=174) and the early colorectal cancer group ( n=92) according to colonoscopic and pathological results. Clinical data of the two groups were analyzed. Logistic regression analysis was used to evaluate the risk factors for early colorectal cancer in patients with dyslipidemia. The results showed compared with the colorectal adenoma group, the early colorectal cancer group had a higher proportion of males (64.1% VS 25.9%), smoking (41.3% VS 14.4%) and drinking (37.0% VS 17.2%) and higher low density lipoprotein cholesterol (LDL-C) (3.06±0.81 mmol/L VS 2.60±0.74 mmol/L) and total cholesterol (TC) values (5.27±1.22 mmol/L VS 4.61±1.06 mmol/L), while the proportion of statin use was lower (27.2% VS 52.9%). There were significant differences in the above indices (all P<0.05). Multivariate logistic regression analysis showed that male ( OR=3.641, 95% CI:1.694-7.826), smoking ( OR=2.920, 95% CI:1.159-7.356), higher LDL-C ( OR=2.203,95% CI:1.481-3.277) and higher TC level ( OR=1.744,95% CI:1.329-2.289) were risk factors for early colorectal cancer in patients with hyperlipidemia, while the history of statin use ( OR =0.469, 95% CI: 0.236-0.932) had a protective effect. Smoking cessation education, early screening of LDL-C, TC level, statin use if necessary to reach the standard lipids and screening of early colorectal cancer should be actively carried out in patients with dyslipidemia.

ABSTRACT

Objective:To determine the accuracy and influencing factors for endoscopic ultrasound (EUS) in predicting the invasive depth of early gastric cancer (EGC).Methods:A retrospective analysis was conducted on data of patients with EGC who were staged T1 with EUS and were treated at Beijing Friendship Hospital from January 2014 to August 2020. The consistency between the invasive depth determined by EUS and postoperative pathology were compared, and the accuracy, the sensitivity and the specificity of EUS were calculated. Logistic regression model was used for univariate and multivariate analysis to explore the relevant factors that affected the accuracy of EUS.Results:A total of 380 lesions were included. While 301 intramucosal (T1a) lesions and 79 submucosal (T1b) lesions were detected with EUS, postoperative pathology diagnosed 320 T1a lesions and 60 T1b lesions. The accuracy of EUS in predicting the invasive depth of EGC was 77.1% (293/380), the sensitivity and the specificity were 83.4% (267/320) and 43.3% (26/60) respectively. Multivariate analysis indicated that the lesions located in the upper 1/3 of the stomach ( OR=2.272, 95% CI: 1.266-4.080, P=0.006), ≥20 mm in size ( OR=2.013, 95% CI: 1.200-3.377, P=0.008) and poorly differentiated cancer ( OR=2.090, 95% CI: 1.018-4.294, P=0.045) were the independent risk factors affecting the accuracy of EUS. Poorly differentiated EGC ( OR=4.046, 95% CI: 1.737-9.425, P=0.001) was the risk factor for over-staging of EUS. Conclusion:EUS is useful in predicting the invasive depth of EGC. Factors affecting the accuracy of EUS include location in the upper 1/3 of the stomach, ≥20 mm in size and poorly differentiated EGC. Additionally, poor differentiation is the risk factor for over-staging of EUS.

ABSTRACT

Objective:To analyze the risk factors for the most common adverse events, i.e. abdominal pain and distension in sedation-free colonoscopy.Methods:This was a multicenter clinical study, in which clinical data of patients including outpatients and inpatients who underwent selective sedation-free colonoscopy at six gastrointestinal endoscopy centers from July 2017 to December 2019 were collected, including patients' general information, complicating diseases, examination time, examination results, and occurrence of adverse events of abdominal pain and distension. Univariate and multivariate logistic regression was performed to analyze the risk factors for adverse events of abdominal pain and distension during sedation-free colonoscopy.Results:A total of 2 394 patients underwent sedation-free colonoscopy, among whom 690 (28.8%) suffered from abdominal pain, and 1 151 (48.1%) experienced abdominal distension. The results of multivariate logistic analysis showed that overweight ( OR=1.33, 95% CI:1.09-1.62, P=0.005), obesity ( OR=1.55, 95% CI:1.14-2.11, P=0.005) and combination of hypertension ( OR=1.58, 95% CI:1.23-2.02, P<0.001) were independent risk factors for abdominal pain during sedation-free colonoscopy, and overweight ( OR=1.40, 95% CI:1.17-1.68, P<0.001) and combination of hypertension ( OR=1.39,95% CI:1.10-1.76, P=0.006) were independent risk factors for abdominal distension during sedation-free colonoscopy. Conclusion:Obesity, overweight and combination of hypertension are independent risk factors for abdominal pain, and overweight and combination of hypertension are independent risk factors for abdominal distension during sedation-free colonoscopy.

ABSTRACT

Acute cholecystitis is a common acute abdominal disease, and it can be classified into grade Ⅰ (mild), grade Ⅱ (moderate), and grade Ⅲ (severe) based on severity. Gallbladder drainage is an important treatment method for patients with severe disease conditions and a high surgical risk. Percutaneous transhepatic gallbladder drainage is commonly used in clinical practice and has a clinical success rate of more than 65%. With the development of endoscopic technology, some centers in China and globally have begun to apply endoscopic gallbladder drainage to the management of acute cholecystitis. This article introduces the methods of gallbladder drainage commonly used in clinical practice, such as percutaneous hepatic gallbladder drainage, endoscopic ultrasound-guided gallbladder drainage, endoscopic transpapillary gallbladder drainage, as well as the progress in endoscopic interventional treatment of acute cholecystitis in recent years.
