BACKGROUND Colonoscopy is the most frequently used diagnostic and therapeutic tool for the treatment of colorectal diseases.Although the complication rate is low,it can be potentially serious.Intussusception is a rare and severe complication often associated with polypectomy.Only a handful of post-colonoscopy intussusception cases have been reported,making this study a valuable addition to the medical literature.CASE SUMMARY Case 1:A 61-year-old man underwent colonoscopy with polypectomy for chronic abdominal pain.The patient experienced abdominal pain 11 hours later but was still discharged after pain management.He was readmitted due to recurring pain.Computed tomography(CT)showed colo-colonic intussusception.Initial conservative management and attempts at endoscopic reduction failed;therefore,laparoscopic right hemicolectomy was performed.Histopathological examination revealed tubular adenomas in the polyps and inflammation in the resected specimens.Case 2:A 59-year-old woman underwent colonoscopy with polypectomy for a polyp in the transverse colon.She experienced upper abdominal pain,fever,nausea,and vomiting 9 hours after the procedure.Emergency CT and blood tests revealed a colo-colonic intussusception near the hepatic flexure and an elevated white blood cell count.Initial attempts at endoscopic reduction failed and conservative treatment showed no improvement.She underwent successful laparoscopic reduction and recovered uneventfully.Histopathological examination of the resected polyp revealed hyperplasia.CONCLUSION Post-colonoscopy intussusception in adults is rare,and polypectomy may contribute to its occurrence.Early diagnosis is crucial,with prompt CT examination serving as key.After excluding malignancies,conservative management and reduction of intussusception should be considered before surgical bowel resection. 展开更多

AIM: To elucidate the prevalence and risk factors for gallstones, primarily focusing on Helicobacter pylori(H. pylori) infection. METHODS: A total of 10016 Chinese subjects, who had undergone physical examination, fasting 13 C urea breath test and abdominal ultrasonography, had sufficient blood test data, and had finished a questionnaire, were included in this cross-sectional study. Participants(n = 1122) who had previous eradication of H. pylori were studied separately. RESULTS: Gallstones were discovered in 9.10% of men and 8.58% of women, with no significant sex difference. Multivariate analyses displayed that age, aspartate aminotransferase, total cholesterol, H. pylori infection, hepatitis C virus(HCV) infection, and fattyliver had a significant association with gallstones(P < 0.05). Successive multiple logistic regression analysis including index of odds ratio(OR) and standardized coefficient(β) indicated that older age(OR/β = 1.056/0.055), H. pylori infection(OR/β = 1.454/0.109), HCV infection(OR/β = 1.871/0.123), and fatty liver(OR/β = 1.947/0.189) had a significant positive association with gallstones. After age stratification, H. pylori infection and fatty liver still had a significant positive association with gallstones in any age-specific groups, whereas HCV infection had a significant positive association in patients aged > 40 years. The prevalence of gallstones among H. pylori-positive, H. pylori-eradicated, and H. pylori-negative subjects was 9.47%, 9.02%, and 8.46%, respectively. The matched analysis showed that gallstones among H. pylori eradicated subjects was significantly lower compared with H. pylori-positive subjects(P < 0.05).CONCLUSION: H. pylori infection and fatty liver have a significant positive association with gallstones. H. pylori eradication may lead to prevention of gallstones. 展开更多

Background:Cholesterol gallstones account for over 80%of gallstones,and the pathogenesis of gallstone formation involves genetic and environmental factors.However,data on the evolution of cholesterol gallstones with various densities are limited.This study aimed to determine the roles of microbiota and mucins on the formation of calcified cholesterol gallstones in patients with cholelithiasis.Methods:Paired gallbladder tissues and bile specimens were obtained from cholelithiasis patients who were categorized into the isodense group and calcified group according to the density of gallstones.The relative abundance of microbiota in gallbladder tissues was detected.Immunohistochemistry and enzyme-linked immunosorbent assay were performed to detect the expression levels of MUC1,MUC2,MUC3a,MUC3b,MUC4,MUC5ac and MUC5b in gallbladder tissues and bile.The correlation of microbiota abundance with MUC4 expression was evaluated by linear regression.Results:A total of 23 patients with gallbladder stones were included.The density of gallstones in the isodense group was significantly lower than that of the calcified group(34.20±1.50 vs.109.40±3.84 HU,P<0.0001).Compared to the isodense group,the calcified group showed a higher abundance of gram-positive bacteria at the fundus,in the body and neck of gallbladder tissues.The concentrations of MUC1,MUC2,MUC3a,MUC3b,MUC5ac and MUC5b in the epithelial cells of gallbladder tissues showed no difference between the two groups,while the concentrations of MUC4 were significantly higher in the calcified group than that in the isodense group at the fundus(15.49±0.69 vs.10.23±0.54 ng/mL,P<0.05),in the body(14.54±0.94 vs.11.87±0.85 ng/mL,P<0.05)as well as in the neck(14.77±1.04 vs.10.85±0.72 ng/mL,P<0.05)of gallbladder tissues.Moreover,the abundance of bacteria was positively correlated with the expression of MUC4(r=0.569,P<0.05)in the calcified group.Conclusions:This study showed the potential clinical relevance among biliary microbiota,mucins and calcified gallstones in patients with gallstones.Gram-positive microbiota and MUC4 may be positively associated with the calcification of cholesterol gallstones. 展开更多

Objective: The diagnoses of patients with duodenal protruding lesions are difficult when using conventional examinations such as computed tomography (CT) and conventional endoscope etc. Thus, we investigated the clinical value of endoscopic ultrasonography (PUS) with miniature ultrasonic probes on the diagnosis and treatment of duodenal protruding lesions. Methods: Patients with duodenal protruding lesions who were indicated for PUS were examined by PUS with 12-15 MHz miniature ultrasonic probes and double-cavity electronic endoscope. According to diagnosis of PUS, those patients were indicated for biopsy and treatment received biopsy, endoscopic resection or surgical excision. The postoperative histological results were compared with the preoperative diagnosis of PUS. Those patients without endoscopic resection or surgical excision were periodically followed up with PUS. Results: A total of 169 patients with duodenal protruding lesions were examined by PUS, of which 40 were diagnosed with cysts, 36 with inflammatory protruding or polyp, 25 with Brunner's gland adenoma, 19 with ectopic pancreas, 17 with gastrointestinal stromal tumor, 12 with extrinsic compression, 12 with minor papilla, 6 with lipoma, 1 with adenocarcinoma and 1 with lymphoma. After PUS examinations, 75 patients received biopsy, endoscopic resection or surgical excision respectively. The postoperative histological results of 70 patients were completely consistent with the preoperative diagnosis of PUS, with 93.33% diagnostic accuracy. The results of follow-up with PUS indicated that duodenal cyst, Brunner's gland adenoma, ectopic pancreas, gastrointestinal stromal tumor and lipoma remained unchanged within 1-3 years. No related complications occurred among all patients that received PUS examinations. Conclusion: PUS is an effective and reliable diagnostic method for duodenal protruding lesions. 展开更多

AIM: To explore the correlation between the expressions of gastrin (GAS), somatostatin (SS) and cyclin, cyclin- dependent kinase (CDK) in colorectal cancer, and to detect the specific regulatory sites where gastrointestinal hormone regulates cell proliferati6n. METHODS: Seventy-nine resected large intestine carcinomatous specimens were randomly selected. Immunohistochemical staining for GAS, SS, cyclin D1, cyclin E, cyclin A, cyclin B1, CDK2 and CDK4 was performed according to the standard streptavidinbiotin-peroxidase (S-P) method. According to the semiquantitative integral evaluation, SS and GAS were divided into high, middle and low groups. Cyclin D1, cyclin E, cyclin A, cydin B1, CDK2, CDK4 expressions in the three GAS and SS groups were assessed. RESULTS: The positive expression rate of cyclin D1 was significantly higher in high (78.6%, 11/14) and middle GAS groups (73.9%, 17/23) than in low GAS group (45.2%, 19/42) (P〈0.05, X^2 high vs low = 4.691; P〈0.05, X^2 middle vs low = 4.945). The positive expression rate of cyclin A was significantly higher in high (100%, 14/14) and middle GAS groups (82.6%, 19/23) than in low GAS group (54.8%, 23/42) (P〈0.01, X2high vs low = 9.586; P〈0.05, X^2 middle vs low = 5.040). The positive expression rate of CDK2 was significantly higher in high (92.9%, 13/14) and middle GAS groups (87.0%, 20/23) than in low GAS group (50.0%, 21142) (P〈0.01, X^2 high vs low = 8.086; P〈0.01,X^2 middle low = 8.715). The positive expression rate of CDK4 was significantly higher in high (78.6%, 11/14)and middle GAS groups (78.3%, 18/23) than in low GAS group (42.9%, 18/42) (P〈0.05, X^2 high vs low= 5.364; P〈0.01, X^2 middle vs low = 7.539). The positive expression rate of cyclin E was prominently higher in low SS group (53.3%, 24/45) than in high (9.1%, 1/11) and middle (21.7%, 5/23) SS groups (P〈0.05, X^2 high vs low = 5.325; P〈0.05, X^2 middle vs low = 6.212). The positive expression rate of CDK2 was significantly higher in low SS group (77.8%, 35/45) than in high SS group (27.3%, 3/11) (P〈0.01, X^2 high vs low = 8.151). There was a significant positive correlation between the integral ratio of GAS to SS and the semi-quantitative integral of cyclin D1, cyclin E, cyclin A, CDK2, CDK4 (P〈0.05, 0% = 0.252; P〈0.01, E^rs = 0.387; P〈0.01,A^rs = 0.466; P〈0.01, K2^rs = 0.519; P〈0.01, K4^rs = 0.434). CONCLUSION: The regulation and control of gastrin, SS in colorectal cancer cell growth may be directly related to the abnormal expressions of cyclins D1, A, E, and CDK2, CDK4. The regulatory site of GAS in the cell cycle of colorectal carcinoma may be at the G2, S and G2 phases. The regulatory site of SS may be at the entrance of S phase. 展开更多

Guo-Qiang XuFor a long time, it was believed that apoptosis and necrosis were the main pathways for cell death, but a growing body of research has shown that there are other pathways. Among these, necroptosis, a regulatory caspase-independent, programmed cell death pathway, is supposed to be of importance in the pathogenesis of many diseases. The mechanism of regulating, in-ducing and blocking necroptosis is a complex process that involves expression and regulation of a series of molecules including receptor interacting protein kinase 1 (RIPK1), RIPK3, and mixed lineage kinase like protein. By blocking or downregulating expression of key molecules in the necroptotic pathway, intestinal inflammation can be affected to some extent. In this paper, we introduce the concept of necroptosis, its main pathway, and its impact on the pathogenesis ofinfammatory bowel disease (IBD) and other intestinal diseases, to explore new drug targets for intestinal diseases, including IBD. 展开更多

AIM:To investigate the sonographic features and diagnostic value of endoscopic ultrasonography (EUS) for duodenal lipomas (DLs).METHODS:A total of eight consecutive patients with DL diagnosed pathologically were included in the study.One EUS expert reviewed the ultrasonic images for all lesions,including the original layer of the duodenal wall,the echo intensity and the echo homogeneity.The size of the lesions and the perifocal structures were also investigated.The diagnosis by EUS was compared with the histological results.RESULTS:Using routine endoscopy,only one case was correctly diagnosed as DL.Four cases were classified as submucosal tumors,and three cases were mistaken for stromal tumors.All tumors appeared as round or oval intensive hyperechoic lesions with distinct anterior borders that originated from the submucosal layer on EUS.Tumors ranged from 8 to 36 mm in size,with an average size of 16 mm.Homogeneous echogenicity was seen in all cases except one that had a tubular structure inside the tumor.Echo attenuation was observed only in the area behind the tumors in five cases,and it was observed both inside and behind the tumors in three cases in which the posterior border was obscure or invisible.Seven (87.5%) cases were correctly diagnosed as DL,and one (12.5%) was mistaken as Brunner's gland adenoma by EUS.Pathologically,all tumors originated from the submucosal layer and consisted of mature fat cells without heteromorphism.Among the fat cells,there was a small amount of thick-wall vessels infiltrating the lymphocytes,and abundant fibrous connective tissues.CONCLUSION:On EUS,DL is featured as an intensive homogeneous hyperechoic submucosal lesion with marked echo attenuation and without involvement of the mucosa. 展开更多

Fishbones are the most commonly ingested foreign bodies that cause gastrointestinal tract penetration. However, fishbones embedded in the gastrointestinal tract that lead to foreign body granulomas that mimic submucosal tumors are rare. Herein, we describe a 56-year-old woman who presented with a 20-day-history of upper abdominal pain. Endoscopy revealed an elevated lesion in the gastric antrum. An abdominal computed tomography scan showed a mass in the gastric antrum and a linear calcified lesion in the mass. An endoscopic ultrasonography examination revealed a 3.9 cm &#x000d7; 2.2 cm, irregular, hypoechoic mass with indistinct margins in the muscularis propria layer. The patient was initially diagnosed as having a submucosal tumor, and subsequent surgical resection showed that the lesion was a foreign body granuloma caused by an embedded fishbone. Our case indicated that the differential diagnosis of a foreign body granuloma should be considered in cases of elevated lesions in the gastrointestinal tract. 展开更多

Heterotopic gastric mucosa(HGM) in the rectum is an extremely rare clinical entity which may be missed or misdiagnosed due to a lack of knowledge.In the present study,a 14-year-old girl visited our hospital due to a 5-year history of repeated hematochezia.Colonoscopy showed a solitary superficial depressed lesion approximately 5 cm in size and a concomitant 1.5 cm deep diverticulum in the rectum.Histological examination of the endoscopic biopsy showed typical ectopic gastric mucosa in the depressed lesion and inside the diverticulum.Narrow band imaging further confirmed the histological results.Endoscopic ultrasound indicated that the lesion originated from the mucosal layer,and partially involved the submucosal layer.Endoscopic submucosal dissection was performed in this patient due to the large size and shape of the lesion.No bleeding,perforation or other adverse events were observed.The presence of HGM in the diverticular cavity greatly increased the surgical difficulty.A literature review was also carried out in our study. 展开更多

BACKGROUND Multiple myeloma(MM)bone disease is indicative of MM,and reduces patient life quality.In addition to oncological,antineoplastic systemic therapy,surgical therapy in patients with MM is an essential treatment within the framework of supportive therapy measures and involves orthopedic tumor surgery.Nevertheless,there are few reports on intramedullary(IM)nailing in the treatment of MM-induced proximal humeral fracture to prevent fixation loss.We here describe a case of pathological fracture of the proximal humerus caused by MM successfully treated with IM nailing without removal of tumors and a review of the current literature.CASE SUMMARY A 64-year-old male patient complaining of serious left shoulder pain and limited movement was admitted.The patient was finally diagnosed with MM(IgAλ,IIIA/II).After treatment of the pathological fracture with IM nailing,the patient's function recovered and his pain was rapidly relieved.Histopathological examination demonstrated plasma cell myeloma.The patient received chemotherapy in the Hematology Department.The humeral fracture displayed good union during the 40-mo follow-up,with complete healing of the fracture,and the clinical outcome was satisfactory.At the most recent follow-up,the patient's function was assessed using the Musculoskeletal Tumor Society score,which was 29.CONCLUSION Early surgery should be performed for the fracture of the proximal humerus caused by MM.IM nailing can be used without removal of tumors.Bone cement augmentation for bone defects and local adjuvant therapy can also be employed. 展开更多

In this experiment, by studying Bcl-2 over-expression transgenic (TG) mice subjected to spinal cord injury (SCI), we investigated whether Bcl-2 could reduce posttraumatic neuronal apoptosis, reduce the range of damage, and improve the behavioral functional recovery after contusive SCI.METHODS: Nine Bcl-2 TG mice and nine control mice were subjected to SCI of moderate severity at T10, with the use of weight dropping (WD) method (impact force 2.5×3.0 g/cm). At times up to 1 day, 7 days and 14 days after SCI, functional defi cits were evaluated with Basso, Beattie, and Bresnahan (BBB) scales, and apoptosis of neurons was investigated by using the TUNEL method. Another three control mice only underwent lamina opening, but were not subjected to SCI, to provide blank comparison.RESULTS: The mean functional scores for the control mice (5.05 ±0.35) were lower than those for the Bcl-2 TG mice (5.45 ±0.15), although the unpaired T-test revealed no signifi cant difference (P=0.67). On the other hand, the number of TUNEL positive neurons and integrated option density (IOD) scores for the Bcl-2 TG mice were both signifi cantly lower than those for the control mice (P〈0.05).CONCLUSIONS: This experiment suggests that overexpression of Bcl-2 may suppress neuronal apoptosis after SCI. Bcl-2 may be an important factor within the central nervous system that can relieve the damage after trauma. 展开更多

BACKGROUND Esophageal bronchogenic cyst(EBC) is a rare congenital disease that is difficult to diagnose preoperatively, and treatment remains controversial.CASE SUMMARY We report a 53-year-old Chinese woman hospitalized in our hospital following the discovery of a submucosal protruding mass of the esophagus by upper endoscopy. A preliminary diagnosis of EBC was made by endoscopic ultrasonography(EUS), and treatment was accomplished by endoscopic submucosal tunnel dissection(ESTD). The pathological results verified the diagnosis. No scar changes or cystic lesion within the original lesion were found under EUS after a 3-mo follow-up.CONCLUSION EUS is valuable for the preliminary diagnosis of EBC and surveillance. ESTD is a safe and effective treatment for EBC. Further evaluation of complications and long-term follow-ups are required. 展开更多

It is a multifactorial disease and the main pathogenesis is the increased secretion of bile cholesterol,which can increase the cholesterol saturation index (CSI) of bile.Patients with CSI greater than 1 are more likely to develop gallstones.Bile is a kind of dark green to yellowish-brown liquid containing> 90% water.Cholesterol,lecithin and bile salts are the three main lipid species in bile and combined to form the main components of gallstones[1]. 展开更多

BACKGROUND Angiolipoma is a benign tumor and is generally found in subcutaneous tissues.Angiolipomas are rare in the gastrointestinal tract,including the stomach.Preoperative diagnosis of the tumor is difficult,although there are several radiological examinations such as computed tomography and endoscopic ultrasound.CASE SUMMARY We report a 24-year-old Chinese man with multiple gastric angiolipomas,with a positive stool occult blood examination. Endoscopic biopsy only showed nonspecific inflammation. Histological examination of the specimen by endoscopic snare resection showed that the tumor consisted of adipose tissues and blood vessels. We also performed a literature review. After the use of proton pump inhibitor,the fecal occult blood test was negative. Due to the difficulty of resecting multiple lesions in the stomach completely and the benign characteristics of angiolipoma,we chose to have regular upper gastrointestinal endoscopy evaluation of the lesion. No evidence of significant change in lesion size was detected after 3-years follow-up.CONCLUSION Gastric angiolipoma is rare,and benign neoplasm should be considered when lesions occur submucosally in the gastrointestinal tract. 展开更多
