OBJECTIVE: To evaluate the safety and prognosis for patients with early esophageal cancer and precancerous lesions after endoscopic submucosal dissection (ESD).
 METHODS: A total of 89 patients were admitted to the Department of internal medicine in the First People's Hospital of Anqing from August 2008 to August 2011. All patients were treated with ESD at the early stage of esophageal cancer and precancerous lesions. The patients' laboratory data and relevant medical history were collected. The postoperative complications and long-term effects of ESD were analyzed.
 RESULTS: Eighty-nine patients were followed up with 100% response rate. Among 89 cases, 16 were early esophageal cancer, 38 were high-grade esophageal neoplasia and 35 were low-grade esophageal neoplasia. The one-time whole piece resection rate, complete resection rate and curative resection rate was 93.3% (84/89), 92.1% (82/89) and 92.1% (82/89), respectively. Two cases suffered intraoperative perforation with a rate of 2.2% and these 2 patients performed the intraoperative endoscopic repair; one case suffered the postoperative delayed bleeding with a rate of 1.1% and the patient underwent the conservative treatment; three cases suffered the esophageal stenosis with a rate of 3.4%. All patients were followed-up for 10-58 (36.3±21.2) months. In this period, one case recurred after ESD for 3 years with a rate of 1.1%; two cases were dead. The three-year survival rate was 97.8%.
 CONCLUSION The early esophageal cancer and precancerous lesions can be treated with ESD. The method is safe and the prognosis is good.

We experienced a case of unusual complication following esophageal reconstruction. In 1969, accidentally the patient swallowed lye and was developed benign esophageal stricture one year later. In 1972, esophageal reconstruction with right colon was done but pus was drained out of the abdominal wound. After then wound disruption and healing were repeated. In 1996, stenosis of colonic graft was found and resection of stenotic area and end to end anastomosis was done. We concluded that it was developed inflammatory change of graft by intraoperative infection.

There are diverse ring-like narrowings in the lower esophagus: mucosal ring, muscular ring, ring-like annular peptic stricture. Esophageal muscular ring is extremely rare and generally asymptomatic. It occurs at the proximal border of the esophageal vestibule that corresponds to the upper end of the lower esophageal sphincter. We experienced a case of lower esophageal muscular ring with a symptom of intermittent mild dysphagia for 40 years and report the findings with a review of the literature.

OBJECTIVES: To investigate the clinical application of endoscopic esophageal dilation in the treatment of corrosive esophageal strictures in children. METHODS: A retrospective analysis was performed on the clinical data of 15 children with corrosive esophageal strictures who underwent endoscopic esophageal dilation in Children's Hospital, Zhejiang University School of Medicine. The clinical features, treatment modality of endoscopic esophageal dilation, number of dilations, complications, and prognosis were reviewed. RESULTS: A total of 96 esophageal dilations were performed in the 15 children with corrosive esophageal strictures, with a median of 6 dilations per child. Among them, 9 children (60%) underwent 6 or more dilations. The children with a stricture length of >3 cm had a significantly higher number of dilations than those with a stricture length of ≤3 cm (P<0.05). The children with strictures in a single segment had a significantly better treatment outcome than those with strictures in multiple segments (P=0.005). No complication was observed during all sessions of dilation. The overall effective rate (including significant improvement and improvement) of endoscopic esophageal dilation treatment was 87%, with 2 cases of failure. CONCLUSIONS Endoscopic esophageal dilation is an effective and relatively safe treatment method for corrosive esophageal strictures in children, and children with strictures in a single segment tend to have a better treatment outcome than those with strictures in multiple segments.

Caustic esophageal burn is a common ailment in clinical practice. In some patients, scar stricture was formed in the late stage of injury, and it seriously undermined quality of life of the patients. We adopted various clinical interventions at an early stage in order to relieve and alleviate the formation and development of corrosive esophageal stricture as a result of chemical injury as well as to avoid invasive operations to make it more acceptable for the patients. This article summarized the progress in etiology, pathological changes, identification, early prevention, and surgical management of corrosive esophageal stricture.

OBJECTIVECongenital esophageal stenosis owing to tracheobronchial remnants (TBR) is a rare condition. This study was conducted to understand the clinical features of TBR.

METHODThe data of the four cases with TBR admitted to our hospital and 76 patients identified from the literature were reviewed. The clinical manifestation, X-ray, endoscopy, biopsy and treatment were studied retrospectively.

RESULTOf the total of 80 cases, 45 were male, 33 were female, and for 2 cases the gender was unknown. Symptoms of dysphagia and regurgitation developed at the age of 1-day to 12-month. Definitive treatment was carried out at the age of 1-month to 16-year. Twenty-seven patients had associated anomalies with esophageal atresia being the most prevalent. X-ray esophagography showed segmental stenosis at the distal third of the esophagus in all patients except three. An abrupt narrow segment at the lower esophagus with marked proximal dilatation was found in 32 cases. Esophagography of 12 cases showed distal esophageal stenosis with tapered narrowing. Esophagography of 20 cases showed flask-shaped shadow of distal esophageal stenosis and one patient showed linear projection of barium at the level of stenosis. Endoscopy found almost complete obstruction of the lower esophageal lumen without signs of the esophagitis or reflux. Esophagoscopic dilatation of the stenosis was attempted in 24 cases, but was ineffective, and 3 patients suffered esophageal perforation. Seventy-nine patients underwent resection of the stenotic segment. Histologic examination of the resected specimen showed cartilage, mucus glands, resembling bronchal tissue. Post-operative complication included anastomotic stenosis, anastomotic leakage, hiatal hernia, and gastroesophageal reflux.

CONCLUSIONTBR should be suspected in patients who present with a typical history of dysphagia after ingestion of solid food. Esophagography and esophagoscopy are the essential means for diagnosis. TBR should be different from achalasia and should be diagnosed by biopsy. Operation is the only choice of treatment.

OBJECTIVETo observe the effect of the modified artificial esophagus on postoperative stenosis in dogs.

METHODSThe models of defected esophagus were established in dogs. The double-layered membrane tube (modifying type) was implanted in the test group (n = 10) and the esophageal stent was further inserted when the stenosis occurred. The single pattern tube (original type) was transplanted to the control group (n = 30). The dilation treatment was performed to relieve the postoperative stenosis; alternatively, the esophageal stent was implanted in the unsuccessful dogs.

RESULTSThe average artificial esophagus removal time was 19.10 days in the test group, which was significantly lower than 39.07 days in the control group (t = 15.6, P = 0.000). No obstruction after removal was observed in the experimental group. The incidence of postoperative stenosis had no significant difference between these two groups.

CONCLUSIONThe double-layered membrane tube can make the tube removal safer by shortening the removal time.
