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 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 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 study the therapeutic value of endoscopy for primary duodenal lesions. Methods Data of 79 consecutive patients with primary duodenal lesions, who underwent endoscopic treatment from January 2015 to January 2018 at Beijing Friendship Hospital, were retrospectively analyzed. Patients were divided into the complication group and the non-complication group, and further grouped according to lesion locations and endoscopic categories. Baseline data of patients, endoscopic treatment, wound closure method, pathological results, the occurrence and outcome of complications were studied. Results A total of 79 patients successfully went through endoscopic treatment, including 59 cases of endoscopic mucosal resection ( EMR) , 5 cases of endoscopic submucosal dissection ( ESD) , 6 cases of full-thickness resection with OTSC metal clips, and 9 cases of endoscopic piecemeal mucosal resection ( EPMR) . In all 79 cases, complications occurred in 8 patients ( 10. 1％) during the perioperative period, all at the duodenal descending segment and duodenal papilla. In all 47 cases whose lesions located at duodenal papilla and duodenal descending segment, the complication incidence was 17. 0％ ( 8/47) , significantly higher than that of non-descending and papilla part [ 0 ( 0/32 ) , P=0. 012 ] . Two ( 2. 5％) cases had complications requiring further intervention with endoscopy or surgery. Among 8 patients with complications, 1 patient ( 2. 1％) developed intraoperative perforation, 1 patient ( 2. 1％) developed delayed bleeding, 6 patients ( 12. 8％) developed mild acute pancreatitis, and these 8 patients recovered after treatment. These 47 patients were further divided into the duodenoscopy group and the gastroscopy group according to endoscopic categories, the complications incidence in the duodenoscopy group ( 28. 0％, 7/25) was also significantly higher than that in the gastroscopy group [ 4. 5％( 1/22) , P=0. 037] . Conclusion Endoscopic treatment is safe and effective for primary duodenal lesions. But for the operations in the duodenal descending segment and the duodenal papilla, as well as in the case of duodenoscopy, it is necessary to be more vigilant about the occurrence of complications.
ABSTRACT
Objective To evaluate the clinical and esophageal dynamics characteristics, and initial treatment effect of patients with untreated achalasia using high resolution manometry. Methods From January 2012 to June 2016, patients newly diagnosed with achalasia were retrospectively recruited. Clinical information, endoscopy and X-ray findings, manometric variables and treatment outcomes were collected and compared among manometric subtypes. Results Among 133 patients with achalasia, 32 ( 24. 0%) were classified as type Ⅰ, 84 ( 63. 2%) as typeⅡ and 17 ( 12. 8%) as typeⅢ. Compared with the typeⅢ, the symptom of regurgitation was more common in the types I and typeⅡachalasia patients ( P=0. 020) . While compared with the type Ⅰ, the score of chest pain was higher in the patients with type Ⅱ and type Ⅲ ( P=0. 006) , as well as the basal lower esophageal sphincter pressure ( P=0. 015, P=0. 023 for type Ⅱ and type Ⅲ, respectively) . Integrated relaxation pressure was similar among the 3 subtypes ( P=0. 158) . Forty-five and 47 patients received pneumatic dilation ( PD ) and peroral endoscopic myotomy ( POEM ) respectively, and all of the patients were followed-up for at least 6 months. The success rate was higher in the POEM group than that of the PD group in all the 3 manometric subtypes, but only the difference between POEM and PD in the type Ⅲ was statistically significant ( 90. 0% VS 40. 0%, P = 0. 041 ) . Conclusion The clinical characteristics and treatment response are different among the 3 achalasia subtypes. Patients with type Ⅲ achalasia are probably the best candidates for POEM.

ABSTRACT
Objective To evaluate a method named “one-step procedure”,i.e.,combined duode-noscopy,laparoscopy and choledochoscopy for choledocholithiasis accompanied with cholecystolithiasis.Meth-ods Fifty-three cases with gallbladder stones combined with common bile duct stones diagnosed from February 2012 to February 2014 were assigned to two groups,29 cases in “one-step procedure”group,who underwent duodenoscopy,laparoscopy and choledochoscopy in one operation,and 24 cases in the control group,who first-ly underwent endoscopic sphincterotomy to remove common bile duct stones,and then LC was performed after several days.The rate of complications related to the procedure,success rate of complete stone removal,length of hospital stay and hospitalization expenses were compared between the two groups.Results All 53 patients underwent the surgery and ERCP procedure successfully.There were no significant differences between the“one-step procedure”group and the control group in complication rates[3.4%(1 /29)VS 12.5%(3 /24),P =0.21],complete stone removal rates[96.6%(28 /29)VS 100.0%(24/24),P =0.37].Differences were sig-nificant in length of hospital stay (6.7 ±1.3d VS 10.9 ±1.6d,P <0.01 )and hospitalization expenses (15 724 ±1 613 yuan VS 19 829 ±2 433 yuan,P <0.05)between the “one-step procedure”group and the control group.Conclusion The “one-step procedure”,the combined duodenoscopy,laparoscopy and chole-dochoscopy,is safe,effective,and has smaller length of hospital stay and lower hospitalization expenses.
ABSTRACT
Objective To explore the value of SpyGlass (direct visualization system) guided laser lithotripsy for large bile duct stones in ERCP.Methods Thirty-three patients with large bile duct stones were randomly assigned to two groups: SpyGlass guided laser lithotripsy group (n =16) and mechanical lithotripsy group (n =17).All patients underwent ERCP procedures for stones extraction.The success rate of complete stone removal, the early complication rate related to the procedure and procedure time were compared between the two groups.Results The success rate of complete stone removal in SpyGlass guided laser lithotripsy group was higher than that of the mechanical lithotripsy group [75.0％ (12/16) VS 41.2％ (7/17) ,P ＜ 0.05].There were no significant differences between two groups in either procedure time [(51.6 ± 18.6) min VS (60.4 ± 12.3) min, P ＞ 0.05] or the early complication rate related to the procedure (18.8％ VS 5.9％ ,P ＞ 0.05).Conclusion SpyGlass guided laser lithotripsy is safe and effective for large bile duct stones.
ABSTRACT
BacKground:AchaIasia of cardia is categorized into 3 subtypes by Chicago cIassification criteria defined by high-resoIution manometry( HRM). These different subtypes present different cIinicaI and esophageaI dynamic characteristics. Aims:To study the cIinicaI and esophageaI dynamic characteristics of patients with achaIasia of cardia categorized by Chicago cIassification criteria. Methods:Twenty-five untreated achaIasia of cardia patients from January 2012 to ApriI 2014 at Beijing Friendship HospitaI,CapitaI MedicaI University were enroIIed. CIinicaI data incIuding cIinicaI symptoms, manifestations of endoscopy and barium meaI radiography and data of HRM were anaIyzed retrospectiveIy. Results:Of the 25 patients,5 patients(20. 0%)were cIassified as type Ⅰ,15(60. 0%)as type Ⅱ and 5(20. 0%)as type Ⅲ. AII patients compIained as having dysphagia,and 26. 7%( 4/15 ) of type Ⅱ patients had chest pain. Incidences of regurgitation in typeⅠ,ⅡandⅢwere 60. 0%(3/5),53. 3%(8/15)and 20. 0%(1/5),respectiveIy,no significant difference was found among the three types(P>0. 05). Incidences of diIatation of esophagus in type Ⅰ,ⅡandⅢwere 60. 0%(3/5),73. 3%(11/15)and 20. 0%(1/5),respectiveIy,no significant difference was found among the three types (P=0. 11). No differences in Iength of Iower esophageaI sphincter(LES),abdominaI LES Iength,LES resting pressure, upper esophageaI sphincter( UES)resting pressure and integrated reIaxation pressure( IRP)among the three types were found(P>0. 05). Incidences of muItipIe swaIIowing and spontaneous UES reIaxation were 32. 0%(8/25)and 24. 0%(6/25),respectiveIy,no significant difference was found among the three types(P>0. 05). Conclusions:Of the patients with achaIasia of cardia ,typeⅡis more common. Large-sampIe muIticenter studies are needed for further research.
