Risk factors of esophageal stricture after endoscopic submucosal dissection for early stage esophageal cancer / 中华消化内镜杂志

Objective To analyze the risk factors for postoperative stricture after endoscopic submucosal dissection (ESD) for early stage esophageal cancer.Methods The data of 362 patients with early esophageal cancer treated by ESD from January 2007 to February 2012 were reviewed to investigate the risk factors of postoperative stricture.Results Esophageal stricture after ESD occurred in 42 patients (11.6％)with a mean time from ESD to stricture of (58.5 ± 12.3) days.The rates of mild,median and severe stricture were 16.7％ (7/42),38.1％ (16/42) and 45.2％ (19/42),respectively.Multivariate analysis revealed that lesion range ＞ 3/4 esophageal circumference (odds ration [OR]:44.2 ; 95％ confidence interval [CI]:4.4-443.6) and tumor invasion beyond m2 (OR:14.2; 95 ％ CI:2.7-74.2) were independent risk factors.Stricture level was related to lesion's circumferential extension (relational coefficient (φ) =0.47,P ＜ 0.05) and tumor invasion depth (relational coefficient (φ) =0.647,P ＜ 0.05).Conclusion Circumferential extension and invasion depth of early esophageal cancer were independent risk factors for post-ESD esophageal stricture and related with the degree of stricture.

Conservative Treatment of Transmural Perforation with Mediastinal Leakage after Balloon Dilation: A Case Report

A 43-year-old man was admitted complaining of swallowing difficulties. The esophagography revealed severe stenosis at the esophagogastric anastomotic site. Esophagography after balloon dilatation showed a transmural perforation with mediastinal leakage. The patient was treated conservatively for one week at which time the esophagography showed no further leakage at the anastomotic site and the good passage of barium. A 2-year follow-up chest computed tomography (CT) showed good patency of the esophageal lumen and the marked resorption of barium in the mediastinum.

Case Report: A new surgical technique for Transverse Vaginal Septum / 대한산부인과학회지

Transverse vaginal septum, especially completely imperforate condition, is a rare congenital anomaly of female genital tract. The patient was 26 years old and visited for primary amenorrhea and low abdominal pain. Secondary sexual characteristics were all normal, but the depth of the vagina was only about 1cm. Hematometra was suspected and two large cystic structures were detected in the pelvis on ultrasonography. Intravenous pyelography and other laboratory results were normal. Vaginoplasty was needed to drain out the hematometra. We tried a new surgical technique using radial incisions of the closed vaginal end. To prevent postoperative contracture, we used a sterile pen case. and educated the patient to dilatate the vagina with that, daily. Here, we report a case of complete imperforate transverse septum with reviews of literatures.

Transverse Vaginal Septum: Difficult Management Concerning Postoperative Stricture: Report of 2 Cases / 대한산부인과학회잡지

Two cases of incomplete transverse vaginal septum with a small opening in the upper third of vagina were presented. One case was a patient presenting at 31 years of age for evaluation of primary infertility and oligomenorrhea. Diagnosis was made by hysterosalpingography, tranvaginal ultrasonography, MRI, and diagnostic pelviscopy for evaluation of abnormality of endopelvic organs. The patient was treated with surgical resection of septum (simple septectomy). Examination 3 months later demonstrated narrowing of the vaginal lumen. Another case was a patient presenting intrauterine pregnancy at 8 weeks and 2 days accompanying transverse vaginal septum with small opening. She had previous septotomy history and presented postoperative scarring. She had septectomy and anastomosis of the mucosa, and presented postoperative narrowing again about a month postoperatively. In this report we describe the two cases of transverse vaginal septum. We also reviewed the literature including diagnostic and treatment guidelines. Prevention of postoperative scarring is the most important factor in management of transverse vaginal septum. For that, first of all, initial septectomy should be done with approximation of the mucosa and postoperative dilatation is necessary. Importance of the initial accurate septectomy is too important to be over-emphasized.
