With a high incidence of esophageal cancer in our country, the treatment of esophageal cancer is a major clinical challenge. Most of the patients with esophageal cancer do not receive treatment at early stage, and the 5-year survival rate is less than 20%. The change of esophageal cancer is a slow, multi-stage, multi-step evolution process, so the early treatment of esophageal cancer is of great significance. For early esophageal carcinoma involving only in the mucous membrane or shallow submucosal membrane, the endoscopic treatment can achieve a radical cure, which is comparable to surgical curative efficacy, and has the advantages of little trauma, less pain and quicker recovery. The 5-year survival rate can be more than 95%. This paper summarizes the progress and development of endoscopic treatment of early esophageal cancer in recent years in China in order to standardize the clinical application and improve the clinical curative efficacy.

OBJECTIVETo compare the long-term efficacy of procedure for prolapse and hemorrhoids (PPH) and Milligan-Morgan hemorrhoidectomy (MMH) in the treatment of III and IV degree internal hemorrhoids.

METHODSOne hundred patients were randomly divided into two groups and received PPH (n=42) and MMH (n=58) respectively. After two years, the efficacy, complications and function of defecation were compared.

RESULTSTwo years after operation, the morbidities of hydrorrhea (2.38% vs 20.69%, P=0.007), dermal neoplasm formation (9.52% vs 25.86%, P=0.040) and narrowing in the caliber of the stools (2.38% vs 18.97%, P=0.027) were significantly lower in PPH group than those in MMH group (P<0.05). The morbidities of overall complication (9.52% vs 25.86%, P=0.040) and overall abnormal function of defecation (9.52% vs 29.31%, P=0.017) were lower in PPH group than those in MMH group (P<0.05). However, there were no significant differences of the morbidity of relapse (14.29% vs 10.34%, P=0.549), patient satisfactory degree (92.86% vs 87.93%, P=0.636) and overall symptom recurrence rate (19.05% vs 25.86%, P=0.424) between the two groups.

CONCLUSIONSLong-term efficacies of procedure for prolapse and hemorrhoids and Milligan-Morgan haemorrhoidectomy in the treatment of III and IV degree internal hemorrhoids are similar. PPH has better safety, less complications and less effect on abnormal function of defecation compared with MMH.

OBJECTIVETo explore the application of sinusitis mixture (SM) in endoscopic sinussurgery, thereby improving clinical curative rate of chronic sinusitis and nasal polyps.

METHODSA totalof 50 chronic sinusitis patients were equally assigned to the experimental group (nasal douching by SM)and the control group (nasal douching by Compound Sodium Chloride Injection). Mucosa tissue 0.1 cmbefore natural opening was collected before surgery, at week 4, 12, and 24 after surgery. Changes ofmucosa cilia cells, goblet cells, stroma of mucosal membrane, inflammatory cells, and mucous glandwere observed. The numbers of goblet cells in the upper epithelia and ciliated cells, as well as their ratioswere calculated.

RESULTSThere was statistical difference in cavity cleaning time, cavity mucosal epithelization time, numbers of goblet cells in the upper epithelia and ciliated cells, as well as their ratio between the two groups (t = -2.342, -2.015, -2.145, respectively; P < 0.05).

CONCLUSIONSM could effectively promote and accelerate cleaning and mucosal epithelization of functional endoscopic sinus surgery, and significantly promote mucosal ciliary structure and function recovery of ostium-meatus nasicomplex.

The technique of endoscopic submucosal dissection is occasionally used for resection of myogenic tumors originating from muscularis mucosa or muscularis propria of stomach and esophagus. However, endoscopic treatments for esophageal myogenic tumors >2 cm have rarely been reported. Herein, we report a case of large leiomyoma originating from muscularis propria in the upper esophagus. A 59-year-old woman presented with dysphagia. Esophagoscopy and endoscopic ultrasonography revealed an esophageal subepithelial tumor which measured 25x20 mm in size, originated from muscularis propria, and was located at 20 cm from the central incisors. The tumor was successfully removed by endoscopic submucosal dissection and there were no complications after en bloc resection. Pathologic examination was compatible with leiomyoma.

OBJECTIVETo evaluate the success rate of dental implants and the changes of sinus membrane thickness after sinus lift in cases of thickened sinus membrane.

METHODSSixteen patients without maxillary sinusitis and with 5-8 mm residual alveolar bone heights were included in this study. The sinus membrane thickeness of these patients were more than 2 mm. All patients received sinus lift surgery and dental implants insertion. The changes of sinus membrane was evaluated by cone-beam CT (CBCT) pre-surgery and 6 months after sinus lift surgery, and the short term success rate of dental implants was also evaluated.

RESULTSA total of 18 implants from 16 subjects were inserted. The thickness of membrane was decreased in 14 cases after sinus lift and increased in 2 cases. All the orifice of maxillary sinus was unobstructed before surgery, one case was obstructed after surgery without inflammation. All the dental implants succeeded.

CONCLUSIONSSinus augmentation with thickened sinus membrane is not contraindication of sinus lift.

OBJECTIVETo investigate the prevention of esophageal varices recurrence by laser inducing esophageal mucosal fibrosis.

METHODSOur study included 42 patients after esophageal varices eradicated by endoscopic varices ligation, and they were divided into 2 groups randomly, each group included 21 patients. One group was assigned to received laser treatment, and indocyanine green solution (1 mg/ml) was injected submucosally, a diode laser (power 10 watts) was applied to the surface from the esophagogastric junction to 5 cm above it. Another group was controlling without any treatments. All patient were followed up by endoscopy every 3 months until 12 months.

RESULTSLaser irradiation was performed safely without any major complications. And lower esophageal mucosa produced fibrosis widely after laser irradiated 1 month. After 12 months follow up, the cumulative recurrence rate was significantly lower than the control group, 14% (3/21) vs 43% (9/21) (chi(2) = 4.20, P < 0.05).

CONCLUSIONSOur study indicates that laser inducing mucous fibrosis is safely and can prevent recurrence of esophageal varices.

We report a case of primary mucosa-associated lymphoid tissue (MALT) lymphoma in the esophagus that manifested as a large submucosal tumor (SMT). Primary esophageal lymphoma is very rare, occurring in less than 1% of all patients with gastrointestinal lymphoma. Only a few cases of MALT lymphoma in the esophagus have been reported in the English literature. A 53-year-old man was referred to Dongguk University Ilsan Hospital (Goyang, Korea) in July 2012 for further evaluation and treatment of an esophageal SMT. Endoscopy showed a cylindrically elongated submucosal mass with normal overlying mucosa in the mid esophagus, 25-30 cm from the incisor teeth. He underwent surgery to confirm the diagnosis. Pathologic findings showed diffuse small atypical lymphoid cells which were stained with Bcl-2, CD20, but not with CD3, CD5, CD23, Bcl-6, or cyclin D1. These cells showed a positive monoclonal band for immunoglobulin heavy chain gene rearrangement. Based on the pathological, immunohistochemical, and molecular biological features, the esophageal mass was diagnosed as extranodal marginal zone B-cell lymphoma of the MALT type.
