ABSTRACT
Objective To summarize the endoscopic appearance,endoscopic ultrasound findings and histopathological characteristics of gastric inflammatory fibroid polyp (IFP) in order to improve diagnosis of IFP.Methods From September 2011 to November 2016,49 patients with pathologically comfirmed gastric IFP,who underwent endoscopy in Taizhou Hospital of Zhejiang Province,were enrolled.The medical history,endoscopic examination,treatment and follow-up were retrospectively enalyzed.Results Among 49 patients with gastric IFP (16 males and 33 females;average age 54 years) the maximum diameter of 33 cases (67.3％) was between 1.0 cm and 2.0 cm.Forty-eight cases had single lesion and one case had multiple lesions.The lesions of 17 cases (34.7％) were located at the anterior wall of gastric antrum,the lesions of seven cases (14.3％) were at the posterior wall of gastric antrum,the lesions of seven cases (14.3％) were at the lesser curvature of gastric antrum and the lesions of seven cases (14.3％) were at the great curvature of gastric antrum.Among the lesions of 41 patients who received endoscopic ultrasonography,28 lesions were located in the submucosa of stomach,13 lesions were located in mucosa and muscularis mucosa.The rate of misdiagnosis of endoscopic ultrasonography was 29.3％ (12/41).The endoscopic ultrasound findings of the lesions included 26 hypoechoic structures,11 hyperechoic structures and four slightly hypoechoic structures.The lesions of all the patients were successfully removed by endoscopic polypectomy without any complication.Thirty-seven lesions were treated by endoscopic submucosal dissection (ESD) and 12 lesions by endoscopic mucosal resection (EMR).All the patients were not clearly diagnosed before operation and were finally diagnosed by pathological examination.Postoperative pathological examination showed that in the suhmucosa and mucosa lamina propria,spindle-shaped cells proliferated and arranged in an interwoven pattern or cells around vessels or mucosal glands formed vortex-like or onion skin like pattern.Forty-seven patients were followed up and the median follow-up time was 31 months.All patients survived withont recurrence or metastasis until the submission of this paper.Conclusions The rate of misdiagnosis of gastric IFP is high before operation,and the diagnosis is depended on histopathological examination.Endoscopic resection is the first choice because the diameter of most lesions are less than 5 cm.
ABSTRACT
Objective To evaluate the safety and effectiveness of three endoscopic methods for re-moval of common bile duct stones (CBDs)accompanied with periampullary diverticula(PAD).Methods A total of 154 patients hospitalized at Taizhou Hospital and Taizhou No.1 People′s Hospital of Zhejiang prov-ince from December 2012 to July 2013 were divided randomly into three groups,i.e.,EST,EPBD and ES-BD group,and received the treatment of EST,EPBD and limited EST plus EPBD (ESBD)to extract CBDs, respectively.After 12 months of follow-up,the rate of full stone clearance,stones clearance rate in one time,the rate of mechanical lithotripsy,the rate of urgent lithotripsy,the average procedures,the average removal time and the complication incidence among three groups were compared.Results The rates of stone clearance in one time in group ESBD was higher than those of group EST and group EPBD (94.12% VS 78.43%,73.08%;P <0.05)with significant difference.The average procedures in group ESBD was lower than that of group EPBD (1.08 VS 1.31,P <0.05),which also showed significant difference.The occur-rence rates of early complication in group ESBD was lower than that of group EPBD (15.69% VS 34.61%, P <0.05).The occurrence rates of post-ERCP hyperamylasemia in group ESBD was lower than that of group EPBD (5.88% VS 21.15%)with significant difference (P <0.05).The incidence of pneumobilia in group EST was higher than those of group EPBD (52.27% VS 26.19%,P =0.013)and group ESBD (52.27%VS 27.66%,P =0.016).Conclusion The stone extraction efficiency of ESBD is better than that of EST and EPBD.Compared with conventional EST,ESBD shows similar safety level,and is safer than EPBD.So ESBD is a safe and effective method to remove CBDs with PAD.
