ABSTRACT
Objective:To evaluate the safety and efficacy of combination of submucosal tunneling endoscopic septum division (STESD) and peroral endoscopic myotomy (POEM) for the treatment of esophageal epiphrenic diverticulum with esophagogastric junction (EGJ) outflow tract disorder.Methods:From October 2017 to August 2021, 6 patients with esophageal epiphrenic diverticulum complicated with EGJ outflow tract disorder receiving combination of STESD and POEM in the Endoscopic Center of the First Affiliated Hospital of Nanjing Medical University were enrolled. The clinical characteristics of the patients were retrospectively analyzed, which included the ratio of male to female, age, course of disease, length of diverticula, location, whether with multiple diverticula, type of EGJ outflow tract disorders, whether the endoscopic technique was successful (the completion of all steps under endoscopy, including tunnel establishment and diverticulum cristae, lower esophageal sphincter and cardia muscularis propria incision); operation time, changes in the severity of clinical symptoms before and after operation (including weight loss, dysphagia, retrosternal pain, and reflux assessed using the Eckardt score), intraoperative and postoperative complications, and follow-up, including whether achieved clinical success (complete or nearly complete improvement of dysphagia, vomiting after eating, retrosternal pain, regurgitation, weight loss, no need for repeat endoscopic intervention during follow-up) and adverse events. Descriptive methods were used for statistical analysis.Results:The male to female ratio of the 6 patients was 3 to 3, the median age was 69.2 years old, and the median disease course was 92.3 months. The median length of the diverticula was 47.5 mm. Diverticulum was located in the right wall of esophagus in 4 cases and in the left wall of esophagus in 2 cases, of which 1 patient was multiple diverticulum of esophagus. Achalasia was found in 5 cases, and EGJ outflow obstruction was found in 1 case. All the 6 patients successfully completed combination of STESD and POEM, and all achieved successful edoscopic technique. The operation time (range) was 55 min (40 to 70 min). Clinical symptom Eckardt score (range) before and after operation was 9.0 (7.0 to 11.0) and 1.3 (1.0 to 2.0), respectively. After operation the clinical symptom improved compared with that before operation. There were no delayed bleeding, perforation, infection, subcutaneous emphysema and other complications and severe adverse events. Six patients were all cured and discharged. Follow-up period was 1 to 50 months. The symptoms of dysphagia, vomiting after eating, retrosternal pain, regurgitation and weight loss were all significantly improved compared with those before operation. There were no severe adverse events and all achieved clinical success.Conclusions:Combination of STESD and POEM is safe and effective in the treatment of esophageal epiphrenic diverticulum with EGJ outflow tract disorder, and has good short-term and long-term effects.
ABSTRACT
Objective To investigate the clinicopathological features and correlation between synchronous multiple early gastric cancer (SMEGC)and single early gastric cancer (EGC).Methods From January 2008 to December 2016,the clinical data of 994 patients with EGC who underwent open or laparoscopic gastrectomy surgery were collected from the electronic medical data base of the First Affiliated Hospital of Nanjing Medical University and Xuzhou No.1 People's Hospital.The data of patients including gender,age,tumor morphologys,tumor location,tumor size,histological type,depth of invasion,lymph nodes metastasis,lymphovascular metastasis,peripheral nerve invasion,and blood types were analyzed.T test and Chi square test were used for statistical analysis.Results Among 994 EGC patients,27 cases (2.7％) were SMEGC,and 967 cases (97.3％) were single EGC.The percentage of male and female of single EGC were 71.4％ (690/967) and 28.6％ (277/967),respectively;the percentage of male and female of SMEGC were 88.9％ (24/27) and 11.1％ (3/27),respectively,and there was statistically significant difference in the gender composition ratio between single EGC and SMEGC (x2 =3.975,P=0.046).The incidence of ulcer in single EGC and SMEGC were 50.6％ (489/ 967) and 29.6 ％ (8/27),respectively,and the difference in the incidence of ulcers between single EGC and SMEGC was statistically significant (x2 =4.653,P=0.031).There were no statistically significant differences between single EGC and SMEGC in gross morphology,depth of invasion,lymph nodes metastasis,lymphovascular metastasis,peripheral nerve invasion,tumor location,pathological type and blood types (all P＞0.05).In the SMEGC patients,the incidence of main lesions invading the mucosa was 48.1％ (13/27) and submucosa invasion was 51.9％ (14/27);and for minor lesions,the corresponding incidences were 77.8％ (21/27) and 22.2％ (6/27),respectively,and the difference was statistically significant (x2 =5.063,P＜0.05).There were no statistically significant differences between the main lesions and minor lesions in tumor size,pathological type,with or without ulcers,gross morphology and tumor location (all P＞0.05).Conclusions The main risk factors of SMEGC are male and no ulcerative lesions.The clinicopathological features are similar between main lesions and minor lesions in SMEGC.
