ABSTRACT

To investigate the evaluation and management of gastrointestinal fistula after upper gastrointestinal tunnel endoscopic surgery, a retrospective analysis was performed on 15 patients with gastrointestinal fistula after upper gastrointestinal tunnel endoscopic surgery, who were treated at the Endoscopy Center of Zhongshan Hospital, Fudan University from January 2012 to October 2022. All patients were treated successfully after comprehensive treatment. Three patients received metal clipping and gastric tube drainage; 10 patients received gastric tube drainage combined with jejunal nutritional tube placement, and 7 of them had gastric tube directly put into the fistula cavity; 2 patients received covered esophageal stent placement combined with jejunal nutritional tube placement. Five patients received wound tissue glue spraying; 2 patients underwent purse-string suture with nylon loops and metal clips after reduced fistula burned by hot biopsy forcep or argon plasma coagulation. The gastrointestinal fistula after tunnel endoscopic surgery is a complex postoperative complication, which needs early detection, careful evaluation and comprehensive treatment.

ABSTRACT

To investigate the feasibility and safety of endoscopic trans-gastric cholecystolithotomy(ETGC) combined with endoscopic retrograde cholangiopancreatography (ERCP) for cholecystolithiasis and choledocholithiasis. Data of patients with cholecystolithiasis and choledocholithiasis who underwent ETGC after ERCP in Zhongshan Hospital Affiliated to Fudan University from November 2018 to April 2019 were analyzed. Six patients with cholecystolithiasis and choledocholithiasis, 4 males and 2 females, were included in this study.The interval between ERCP and ETGC ranged from 1 to 77 days (median 5 days). All the 6 patients successfully completed ETGC after ERCP, with a surgical success rate of 100%. All the patients had multiple cholecystolithiasis and one patient was complicated with gallbladder polyps.The ETGC operation time was 22-100 min (median 65 min), and the length of hospital stay was 3-9 d (median 6.5 d). Two patients had dull pain in the upper abdomen and increased body temperature after surgery. Abdominal ultrasound in one patient suggested local effusion in the right upper abdomen.Both patients improved after conservative treatment.None of the patients had cholecystitis and cholangitis related symptoms such as right upper abdominal pain or fever during postoperative follow-up, and the follow-up rate was 100%with median follow-up time of 18 month.All the 6 patients underwent abdominal ultrasound examination after surgery. No recurrence occurred in 5 patients. One of the patients showed cholesterol crystals in the gallbladder wall and bile mud deposition.ETGC combined with ERCP is safe and feasible for cholecystolithiasis and choledocholithiasis.

ABSTRACT

Objective:To evaluate the safety, efficacy and long-term survival of endoscopic submucosal dissection (ESD) for colorectal precancerous lesions and early cancer in the elderly over 80 years old.Methods:Clinical data of colorectal precancerous lesions and early cancer treated with ESD from January 2007 to December 2014 at Endoscopy Center of Zhongshan Hospital, Fudan University were retrospectively analyzed. A total of 721 patients with 778 lesions were included in this study. These patients were stratified by age: the super-elderly group (≥80 years old, 55 patients, 7.6%) and the non-super-elderly group (<80 years old, 666 patients, 92.4%). The outcomes of ESD, complication incidences, pathological characteristics, and long-term survival were compared between the two groups.Results:Except that the incidence of chronic concomitant diseases in the super-elderly group was significantly higher than that in the non-super-elderly group [54.5% (30/55) VS 31.5% (210/666), P<0.001], other baseline characteristics were not significantly different ( P>0.05). There were no significant differences in the complete resection rate [93.1%(54/58) VS 95.3%(686/720)], the R0 resection rate [89.7% (52/58) VS 93.2% (671/720)], the curative resection rate [84.5% (49/58) VS 90.3% (650/720)], the complication incidence [5.5% (3/55) VS 2.7%(18/666)], or the median hospitalization (2.98 days VS 2.54 days) between the two groups (all P>0.05). The three-year overall survival rates of the super-elderly group and non-super-elderly group were 95.8% and 98.0%, respectively, and the five-year overall survival rates were 85.1% and 97.4%, respectively. Conclusion:Colorectal ESD is safe and effective for elderly patients (age ≥80 years old) despite a significantly higher incidence of chronic concomitant diseases than that in the non-super-elderly patients.

ABSTRACT

Objective:To compare the clinical and prognostic characteristics of ovarian endometrioid carcinoma (OEC) patients with synchronous endometrial lesions and patients with pure OEC.Methods:A retrospective review of the medical records of patients received initial treatment and a postoperative pathological diagnosis of OEC at Peking University People′s Hospital between August 1998 and December 2017 were performed. According to the inclusion criteria, a total of 56 patients with OEC were included in the study, including 13 patients concurrent with simultaneous endometrial lesions (Group A) and 43 patients with pure OEC (Group B).Results:Patients with synchronous endometrial lesions accounted for 23% (13/56). Mean age of Group A at diagnosis was (44.9±8.3) years old, 2/13 of patients were postmenopausal, and no one had a history of hypertension, the first symptom of 5/13 people was irregular vaginal bleeding. Mean age of Group B patients at diagnosis was (52.7±10.2) years old, 53% (23/43) of patients were postmenopausal, and 28% (12/43) patients had the history of hypertension, the first symptom of 4 (9%, 4/43) people was irregular vaginal bleeding. The differences of age, menopause status, history of hypertension and initial symptoms between the two groups were statistically significant (all P<0.05). There were no significant differences in fertility history, dysmenorrhea history, age of menarche, history of endometriosis, preoperative and postoperative CA 125 level, International Federation of Gynecology and Obstetrics (FIGO) stage, tumor grade, metastatic site and platinum-based chemotherapy drug resistance between the two groups (all P>0.05). The overall 5-year survival rate of OEC patients was 91.6%, and the overall 5-year progression-free survival rate was 76.6%. Among them, the 5-year survival rate of the OEC concurrent with simultaneous endometrial lesions group was 80.2%, and the pure OEC group was 93.4%; the 5-year progression-free survival rate of the OEC concurrent with simultaneous endometrial lesions group was 74.1%, and the 5-year progression-free survival rate of the pure OEC group was 77.3%. There were no significant differences between the two groups (all P>0.05). Multivariate analysis showed that the independent factors for the prognosis of OEC patients were FIGO stage ( P=0.006) and residual lesion size ( P=0.020). Conclusions:OEC patients have a high proportion of simultaneous endometrial lesions. OEC with simultaneous endometrial lesions are younger than patients with pure OEC. Synchronous endometrial lesions do not affect the prognosis of patients with OEC.

ABSTRACT

To study the clinical effect of non-ampullary duodenal mucosal lesions treated by endoscopic resection. A retrospective analysis was performed on the data of 58 cases of duodenal non-ampullary mucosal lesions treated by endoscopic resection from January 2016 to June 2019 from 3 hospitals. Among 58 cases, 27 lesions (46.6%) were located in the duodenal bulb and 31 (53.4%) in the duodenal descending part (including the ball-drop boundary). Forty-six patients (79.3%) received endoscopic mucosal resection, 7 (12.1%) received endoscopic submucosal dissection and 5 (8.6%) received pre-cut endoscopic mucosal resection. Few postoperative complications were found except for 1 case of intraoperative bleeding, 1 case of delayed bleeding 2 days after surgery, 1 case of lesion residual and 2 cases of postoperative abdominal pain. No perforation occurred. Endoscopic treatment of non-ampullary duodenal mucosal lesions is safe and effective.

ABSTRACT

Objective:To investigate the clinical value of early gastroscopy for patients with hypopharyngeal cancer.Methods:A total of 231 cases of hypopharyngeal cancer diagnosed and treated in the First Affiliated Hospital of Xiamen University from January 2010 to December 2014 were included in the retrospective analysis. The 5-year survival rate of hypopharyngeal cancer and patients accompanied with synchronous esophageal cancer (including early and advanced esophageal cancer), as well as the detection rate of synchronous esophageal cancer by gastroscopy and systemic PET-CT examination were statistically analyzed.Results:The 5-year survival rate of hypopharyngeal cancer was 38.96% (90/231). The 5-year survival rates of 62 patients accompanied with synchronous esophageal cancer and 169 patients without were 27.42% (17/62) and 43.20% (73/169), respectively, with statistic difference ( χ2=4.747, P=0.029). The 5-year survival rate of 49 patients accompanied with synchronous early esophageal cancer was 30.69% (17/49). Among the 13 patients with synchronous progressive esophageal cancer, none had a survival period of 5 years, which was significantly different compared with the patients with synchronous early esophageal cancer ( P=0.013). The detection rates of synchronous esophageal carcinoma by gastroscopy and by systemic PET-CT were 26.84% (62/231) and 14.29% (33/231), respectively, with statistic difference ( χ2=11.14, P<0.01). The detection rates of synchronous early esophageal carcinoma by gastroscopy and by systemic PET-CT were 21.21% (49/231) and 8.66% (20/231), respectively, and the difference was also statistically significant ( χ2=14.328, P<0.01). Conclusion:Hypopharyngeal cancer accompanied with synchronous esophageal cancer is of high risk, which affects the survival rate of patients. Early gastroscopy in hypopharyngeal cancer patients can significantly improve the detection rate of synchronous esophageal cancer, which helps to design individualized regimen to improve the survival rate of patients.

ABSTRACT

Objective:To evaluate the efficacy and safety of endoscopic trans-gastric gallbladder-preserving polypectomy in treatment of gallbladder polyps.Methods:A retrospective analysis was performed on data of 25 patients with gallbladder polyps who underwent endoscopic trans-gastric gallbladder-preserving polypectomy in the endoscopy center of Zhongshan Hospital from September 2017 to August 2019. Completion of operation, operation time, postoperative hospital stay, complications and follow-up results of patients were obtained and analyzed.Results:There were 13 cases of single polyp and 12 cases of multiple polyps, 13 cases of simple gallbladder polyps, and 12 cases of polyps and gallstones. The maximum diameter of polyps was 0.2-1.5 cm. The procedure failed in 1 patient (4%) because of the severe adhesion of abdominal cavity and disappearance of gallbladder when passing through the gastric wall. Twenty-four patients (96%) were successfully treated with endoscopic trans-gastric gallbladder-preserving polypectomy. The operation time was 67.1±26.8 min (35-140 min). The median hospital stay was 4 d (2-5 d). No severe adverse events including delayed bleeding, delayed perforation, diffuse peritonitis or abdominal abscess occurred. During the median follow-up time of 8 months (0-23 months), no patient was lost, no recurrence of polyps and no severe adverse events related to metal clips occurred.Conclusion:Endoscopic trans-gastric gallbladder-preserving polypectomy shows good short-term efficacy and is technically feasible, however, long-term outcome still requires further research.

ABSTRACT

Objective:To study the efficacy of dental floss traction-assisted endoscopic submucosal dissection (ESD) for gastric angle mucosal lesions.Methods:Data of 127 patients with gastric angle mucosal lesions admitted to the endoscopic center of the First Affiliated Hospital of Xiamen University from January 2015 to December 2018 were retrospectively analyzed. According to the surgical methods, patients were divided into the dental floss traction-assisted ESD group (the traction group, n=51) and the traditional ESD group (the traditional group, n=76). The 41 fibrosis cases were further divided into the traction group (n=23) and the traditional group (n=18). The operation time, en block resection rate, curative resection rate and the incidence of adverse events such as bleeding, muscle layer injury and perforation were compared between the two groups.Results:There was no significant difference in age, sex, lesion size or morphology between the traction group and the traditional group ( P > 0.05). The operation time of the traction group was significantly shorter than that of the traditional group (65.4±36.5 min VS 103.5±43.2 min, P=0.012). The en block resection rate was higher in the traction group [100.00% (51/51) VS 90.79% (69/76), P=0.026], and the curative resection rate was higher too [94.12% (48/51) VS 81.58% (62/76), P=0.042]. The incidences of muscular layer damage [5.88% (3/51) VS 25.00% (19/76), P=0.010] and intraoperative bleeding [47.06% (24/51)VS 82.89% (63/76), P=0.010] were lower in the traction group. Perforation occurred in two patients (2.63%) of fibrosis in the traditional group; no perforation occurred in the traction group. There was no significant difference in the perforation incidence ( P=0.243). In the cases of fibrosis, the operation time of the traction group was significantly shorter compared with that of the traditional group (81.4±29.3 min VS 119.3±37.6 min, P=0.010). The en block resection rate and curative resection rate were also higher in the traction group [100.00% (23/23) VS 72.22% (13/18), P=0.007; 95.65% (22/23) VS 72.22% (13/18), P=0.035]. The incidences of muscular layer damage [8.70% (2/23) VS 72.22% (13/18), P=0.001] and intraoperative bleeding [78.26% (18/23) VS 100.00% (18/18), P=0.035] were lower in the traction group. Conclusion:The dental floss traction-assisted ESD is safe and effective for gastric angle mucosal lesions and fibrotic lesions, with shorter operation time, higher curative resection rate and lower incidence of adverse events.

ABSTRACT

Objective:To investigate the indication of pre-cut-endoscopic mucosal resection (pre-cut-EMR) on the treatment of colorectal laterally spreading tumors (LSTs).Methods:A retrospective study was performed on data of colorectal LSTs patients, who underwent pre-cut-EMR in Wuxi Second People’s Hospital and Zhongshan Hospital from January 2014 to June 2019. The relationships between the clinical characteristics of the lesions and the success rate and complications of pre-cut-EMR were analyzed.Results:Data of 132 colorectal LSTs cases were included in the study. Morphology of 29 (22.0%) LSTs were homogeneous granular type, 43 (32.6%) LSTs were mixed non-granular type, 58 (43.9%) LSTs were flat elevated type, and 2 (1.5%) LSTs were pseudo-depressed type. The diameter of lesions was 2.3±1.5 cm (ranged from 2.0 cm to 5.0 cm). Among the 132 LSTs, 36 (27.3%) tumors were located in rectum, 15 (11.4%) in sigmoid colon, 10 (7.6%) in descending colon, 17 (12.9%) in splenic flexure of colon, 21 (15.9%) in transverse colon, 24 (18.2%) in hepatic flexure of colon, 6 (4.5%) in ascending colon, and 3 (2.3%) in cecum. The histopathological diagnoses of the 132 LSTs included low grade intraepithelial neoplasia in 58 cases (43.9%), high grade intraepithelial neoplasia in 69 cases (52.3%), intramucosal carcinoma in 2 cases (1.5%), and canceration in 3 cases (2.3%). Pre-cut-EMR was achieved in all 132 patients, and the operation time was 25.3±13.6 min (ranged 20-65 min). The rate of en bloc resection and complete resection were 95.5% (126/132) and 100.0% (132/132), respectively. Two cases (1.5%) had intraoperative perforation, and were both located in the sigmoid colon with the diameter of 4.0 cm and 4.5 cm, respectively. Twelve cases (9.0%) had immediate bleeding during operation, and 2 cases (1.5%) had delayed bleeding after operation. Patients had been followed up for 6-24 months, the wound healed well after operation, and no local recurrence was found.Conclusion:Pre-cut-EMR is an effective and safe therapy for colorectal LSTs with diameter less than 4.0 cm.

ABSTRACT

Objective To improve the detection rate of early esophageal cancer during endoscopy by construction of artificial intelligence assistant diagnosis system. Methods A total of 2400 esophageal images were collected from Zhongshan Hospital of Fudan University from January 2016 to December 2017, including 1200 images of early esophageal cancer and 1200 images of normal esophageal mucosa. The lesions in pictures were marked with rectangular box by using computer program. Among them, 2000 pictures were divided into the training set and 400 pictures into the test set. An assistant diagnostic model of early esophageal cancer was established by back propagation algorithm in computer deep learning. The training model was tested and the sensitivity and specificity of the system at different cut-off points in the test set was calculated. Receiver operating characteristic ( ROC) curve was used to evaluate the performance of the diagnostic model. Results The area under ROC curve ( AUC) of the auxiliary diagnostic model was 0. 9961. The sensitivity and specificity were satisfactory. Conclusion The deep learning model constructed in this study has good specificity, sensitivity and AUC value in the diagnosis of early esophageal cancer, and can assist endoscopists in real-time diagnosis in clinical examination.

ABSTRACT

Objective@#To evaluate the safety and efficacy of dental floss traction-assisted endoscopic submucosal dissection (DFS-ESD) for rectal neuroendocrine neoplasm (NEN).@*Methods@#A retrospective cohort study was performed. Clinical data of rectal NEN patients undergoing ESD at Endoscopy Center of Zhongshan Hospital, Fudan University from January 2016 to December 2017 were retrospectively analyzed. Inclusion criteria: 1) age of 18 to 80 years old; 2) maximal diameter of lesions <1.5 cm; 3) tumor locating in the submucosa without invasion into the muscularis propria; 4) no enlarged lymph nodes around bowel and in abdominal cavity; 5) ESD requested actively by patients. A total of 37 patients were enrolled, including 23 male and 14 female cases with mean age of (56.0±11.3) years. All the lesions were single tumor of stage T1, and the mean size was 0.8±0.2(0.5-1.2) cm. Postoperative pathology revealed all samples as neuroendocrine tumors (NET). Seventeen patients received DFS-ESD treatment (DFS-ESD group) and 20 patient received conventional ESD treatment (conventional ESD group). In DFS-ESD group, after the mucosa was partly incised along the marker dots, the endoscopy was extracted, and the dental floss was tied to one arm of the metallic clip. When the endoscope was reinserted, the hemoclip was attached onto the incised mucosa; another hemoclip was attached onto normal mucosa opposite to the lesion in the same way. The submucosa was clearly exposed with the traction of dental floss and the resection could proceed. The conventional ESD group received the traditional ESD operation procedure. The operation time, modified operation time (remaining time after excluding the assembly time of dental floss traction in DFS-ESD group), en bloc resection rate, R0 resection rate, morbidity of operative complication, recurrence and metastasis were compared between two groups.@*Results@#The average tumor size was (0.8±0.2) cm in DFS-ESD group and (0.7±0.2) cm in conventional ESD group (t=0.425, P=0.673). According to postoperative pathological grading of rectal neuroendocrine neoplasm, 13 were G1 and 4 were G2 in DFS-ESD group, while 17 cases were G1 and 3 cases were G2 in conventional ESD group without significant difference (P=0.680). There were no significant differences in baseline data between in the two groups (all P>0.05). All the basal resection margins were negative, the en bloc resection rate was 100% and the R0 resection rate was 100%. Pathological results showed tumor tissue close to the burning margin in 5 cases of conventional ESD group and in 2 cases of DFS-ESD group (P=0.416). The operation time was (17.9±6.6) minutes in conventional ESD group and (14.7±3.3) minutes in DFS-ESD group (t=1.776, P=0.084). The modified operation time of DFS-ESD group was (11.9±2.8) minutes, which was significantly shorter than (17.9±6.6) minutes in conventional ESD group (t=3.425, P=0.002). The hospital stay was (2.3±0.6) days and (2.0±0.5) days in conventional ESD group and DFS-ESD group, respectively, without significant difference (t=1.436, P=0.160). No patient was transferred to surgery, and no delayed bleeding or perforation occurred in either group. There was no recurrence or primary tumor-related death, and all the patients recovered well during a follow-up period of 14(1-24) months.@*Conclusion@#Dental floss traction-assisted ESD for rectal neuroendocrine neoplasm can simplify operation and ensure negative basal margin.

ABSTRACT

Endoscopic submucosal dissection (ESD) is the gold standard technique for performing en bloc resection of large superficial tumors in the upper and lower gastrointestinal tract. It has not started in China until early 2006, when it was introduced at Endoscopy Center of Zhongshan Hospital. However, ESD is technically more difficult and can result in more complications, limiting its development in China. At present, reports about ESD training system in China are still not available. Therefore, our center continuously explored and gradually established structured training courses relied on the live pig model. Between 2009 and 2013, we held 23 hands-on ESD training workshops with 550 endoscopists. Questionnaires were distributed via e-mail, and there were 460 participants performing ESD in a step-up approach on the live pigs. More than one half of trainees could perform ESD with en bloc resection in the imaginary "lesion" of colon and stomach, and there were higher rates of hemorrhage and perforation occurring in colorectal ESD as compared to gastric ESD. After graduating from our hands-on workshop, up to over 90% of participants started ESD practice in their home hospitals. It was mostly provided by high-grade hospitals (IIIA) which played a major role as tertiary referral centers, covering almost all provinces and major cities in China. The training on live pig model revealed to be safe and effective as a prior step to its application in humans. It may enable novice endoscopists to acquire ESD skills and start performing ESD as soon as possible. The role of adequate training is of course to influence the spread of this technique and promote ESD development around China.

ABSTRACT

Objective@#To investigate the feasibility and safety of endoscopic trans-gastric gallbladder-preserving cholecystolithotomy (ETGC) for gallstones.@*Methods@#The clinical data of 84 cholecystolithiasis patients, who received ETGC at Endoscopic Center of Zhongshan Hospital from March 2017 to May 2019 were analyzed retrospectively. The operation completion rate, operation time, complications and recurrence of calculus were summarized.@*Results@#In the 84 cases of cholecystolithiasis, there were 19 cases (22.6%) of single stone, 53 cases (63.1%) of multiple stones, and 12 cases (14.3%) of gallstones with gallbladder polyps. A total of 82 patients (97.6%) successfully completed ETGC with median operation time of 88 min. Ten patients (12.2%) suffered from abdominal pain after operation, of which 6 patients relieved after conservative treatments. The other 4 cases, including 2 cases of hemoperitoneum, 1 case of biliary fistula, and 1 case of choledocholithiasis with obstructive jaundice, were recovered after corresponding interventions. As of June 14, 2019, 5 cases were lost to follow-up (follow-up rate was 93.9%, 77/82). Residual stones were found in 2 cases (2.6%, 2/77). Stone recurrence was discovered in 4 cases (5.2%, 4/7), and 2 cases (2.6%, 2/77) had cholesterol crystallization in gallbladder.@*Conclusion@#ETGC is minimally invasive, feasible and safe in treatment of cholecystolithiasis, and can retain the function of gallbladder. However, how to completely remove the stones and avoid residue by ETGC still needs further exploration, and its long-term efficacy still needs further observation.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the risk factors of carcinogenesis of large colorectal polyps (diameter ≥ 10 mm) found by colonoscopy.</p><p><b>METHODS</b>Clinicopathological and follow-up data of 418 consecutive patients who were diagnosed as colorectal polyps with diameter≥10 mm by colonoscopy at two endoscopy centers of the Affiliated Wuxi Second People's Hospital, Nanjing Medical University (n=207) and Zhongshan Hospital, Fudan University (n=211) from January 2015 to December 2016 were retrospectively collected. High-grade intraepithelial neoplasia and cancer were defined as malignancy in this study. Chi square test was used for univariate analysis, and logistic regression was used for multivariate analysis (in patients with multiple polyps, if the pathological findings were all low grade intraepithelial neoplasia, one polyp with the largest diameter was selected to enter the model; in patients with high grade intraepithelial neoplasia, one polyp of high grade intraepithelial neoplasia with the largest diameter was selected to enter the model). Associated risk factors of malignancy were analyzed.</p><p><b>RESULTS</b>Among the 418 patients, 278(66.5%) were male and 140(33.5%) were female, with mean age of (58.7±10.2) (range 15-87) years old. Of 398 patients undergoing endoscopic treatment with resected 456 polyps, 142 cases with 150 polyps were malignant, including 134 polyps of high-grade intraepithelial neoplasia and 16 polyps of intra-mucosal cancer. The other 20 patients showed negative elevation signs after endoscopic submucosal injection and were transferred to surgery, of whom 20 polyps were resected. Histological examination of these 20 polyps indicated invasive cancer. Univariate analysis showed that age ≥ 50 years [40.5% (150/370) vs. 25.0% (12/48), χ² =4.323, P=0.041], multiple polyps [77.5%(31/40) vs. 34.7%(131/378), χ² =12.900, P=0.001], polyp locating at rectum [59.0%(36/61) vs. 32.3%(134/415), χ² =22.736, P=0.000], polyp diameter ≥31 mm [74.1%(20/27) vs. 33.4%(150/449), χ² =36.493, P=0.000] and tubular villous adenoma [67.4%(120/178) vs. 16.8%(50/298), χ² =71.810, P=0.000] were associated with malignancy. Multivariate analysis showed that age ≥ 50 years(OR=2.473, 95%CI:1.209-5.058, P=0.013), multiple polyps (OR=2.472, 95%CI: 1.300-4.702, P=0.006), polyp locating at rectum (OR=1.253, 95%CI: 1.091-1.439, P=0.001) and the polyp diameter ≥31 mm (OR=1.500, 95%CI:1.196-1.881, P=0.000) were independent risk factors for malignancy of large colorectal polyps. The mean follow-up time was (9.6±4.2) months. During the follow-up period, 86 patients (20.5%) who received endoscopic resection developed recurrent adenoma which all were successfully removed by colonoscopic polypectomy. Two patients(0.5%) developed colon cancer 6 months after endoscopic resection and both underwent radical surgery and chemotherapy. Their previous pathology from endoscopic resection was tubular villous adenoma and high grade intraepithelial neoplasia. All the patients were alive during the follow-up period.</p><p><b>CONCLUSIONS</b>Age ≥50 years old, multiple polyps, polyps locating at rectum and polyps with diameter ≥ 31 mm are the risk factors of malignancy. Emphasized examination should be recommended for those with the above mentioned risk factors to avoid missed diagnosis and misdiagnosis. The choice of endoscopic treatment must be reasonable for curative resection.</p>

ABSTRACT

Objective To explore the feasibility, safety and effectiveness of endoscopic submucosal dissection ( ESD) in the treatment of the synchronous multiple early cancer or precancerous lesions in esophageal and stomach. Methods A retrospective study was conducted on the data of 5 patients with synchronous multiple early cancer or precancerous lesions in esophageal and stomach who were treated by ESD in Endoscopy Center of Zhongshan Hospital from January 2008 to December 2013. The characteristics of lesions, and results of therapy and follow-up were analyzed. Results All 5 patients were male with mean age of 67. 8±13. 1 years. The mean size of esophageal lesions was 2. 1±0. 9 cm with 1 lesion located in the upper esophagus and 4 in the middle. The mean size of gastric lesions was 2. 5±1. 5 cm with 2 lesions in the antrum, 2 in the gastric angle and 1 in cardia. Lesions in 4 cases were removed at the same time and 1 at different times. All lesions achieved complete resection. Postoperative pathological results showed that there were 2 cases of esophageal precancerous lesions with gastric precancerous lesions, 2 cases of esophageal precancerous lesions with early gastric cancer, and 1 case of early esophageal cancer with early gastric cancer. The 5 patients with 10 lesions all achieved curative resection. Postoperative esophageal stricture occurred in 1 case, which was improved after dilation. Median follow-up time was 72 months, when 3 patients survived and 2 patients died. However, the cause of death was not associated with the treatment. Conclusion ESD is a minimally invasive endoscopic method for treating synchronous multiple primary early cancers in esophagus and stomach.

ABSTRACT

Objective To explore the clinical value of dental floss traction-assisted endoscopic full-thickness resection ( EFTR) for muscularis propria tumor in gastric fundus. Methods Twenty-four patients with muscularis propria tumor in gastric fundus and undergoing EFTR with traction of dental floss from January to December in 2016 in Endoscopy Center of Zhongshan Hospital were enrolled in the trial group. Another 24 patients undergoing traditional EFTR from January to December in 2015 were enrolled in the control group. The control group was paired with the trial group according to tumor size. The differences in tumor resection time, hospitalization time, and complication rate were compared between the two groups. Results There were no significant differences in the mean age and gender composition between the two groups ( both P>0. 05) . The tumor resection time of the trial group was shorter than that of the control group ( 10. 8 ± 2. 8 min VS 19. 0 ± 4. 7 min, t = 7. 298, P<0. 05 ) . There was no significant difference in postoperative hospital stay between the two groups ( 3. 2 ± 0. 5 days VS 3. 2 ± 0. 5 days, t=0. 291, P=0. 772) . No postoperative delayed bleeding or perforation and other complications occurred in the two groups. Conclusion Dental floss traction-assisted EFTR is safe and effective to treatment of muscularis propria tumors in gastric fundus, which can expose the tumor boundary, so that the surgical level may be clearer to simplify the operation and reduce the tumor resection time.
