Management of a solitary pulmonary arteriovenous malformation by video-assisted thoracoscopic surgery and anatomic lingula resection: video and review.
Pulmonary arteriovenous malformations are abnormal communications between the pulmonary arterial and venous vasculature leading to a right-to-left blood shunt. Based on possible complications, including hypoxemia, hemorrhage, infection and paradoxical embolism, deactivation of the malformation from the circulation is the treatment option of choice, either by interventional embolization or by surgery. Embolization is less invasive and has widely replaced surgery, but bears the risk of revascularization, recanalization and downstream migration of the device with paradoxical embolism. ⋯ Although interventional embolism of the feeding artery of a pulmonary arteriovenous malformation is the current therapeutic gold standard, minimally invasive anatomic lung resection by video-assisted thoracoscopic surgery can be considered, especially for the treatment of solitary large arteriovenous malformations. By anatomic lung resection, the risk of recanalization, collateralization and peri-interventional paradoxical embolism may be reduced.

Full-thickness laparoendoscopic excision has been reported for complex endoscopically unresectable colonic polyps. However, the endpoints used in these studies vary significantly and therefore making definitive conclusions regarding the novel procedure would be improved if a common data set were adopted. This study sought to define most appropriate endpoints that should be measured and reported for research on full-thickness laparoendoscopic excision of colonic polyps. ⋯ This study has developed a provisional consensus on a minimum number of feasible and clinically meaningful outcome measures to use in studies of full-thickness laparoendoscopic excision of colonic polyps. Widespread adoption will allow better reporting of the technique and more efficient development in clinical practice.

Laparoscopic resection is a standard procedure for gastric submucosal tumors. Herein, we analyzed the features of various laparoscopic approaches. ⋯ For gastric submucosal tumors with appropriate locations and growth types, laparoscopic tailored resection which facilitates safer and more precise resection can be good alternative treatment option.

Per-oral endoscopic myotomy (POEM) is an emerging treatment for achalasia. Pneumatic dilation, botulinum toxin injection, and previous myotomy increase the difficulty of subsequent Heller myotomy, but their impact on POEM remains unknown. The purpose of this study was to compare patients who had undergone prior treatment for their achalasia to those undergoing POEM as an initial therapy. ⋯ Per-oral endoscopic myotomy is a safe and effective treatment for achalasia which improves dysphagia and disease-specific quality of life. Previous endoscopic or laparoscopic treatment of achalasia does not affect the performance or early outcome of POEM.

Recurrent tracheoesophageal fistula (RTEF) is a serious complication after primary repair of esophageal atresia and tracheoesophageal fistula (EA/TEF). Treatment of RTEF involved an open surgery by thoracotomy. Technically it is a challenge with a high morbidity and mortality. Congenital tracheoesophageal fistula (CTEF) traditionally involved an open surgery by thoracotomy or cervicotomy. Many endoscopic techniques have been developed since the past decades: thoracoscopic or bronchoscopic approach for the treatment of RTEF and CTEF; nevertheless, optimal treatment is not still determined because of few numbers of patients, short-term follow-up, and different procedures. We report our experience and evaluated the efficacy in the chemocauterization of CTEF and RTEF, with the use of 50% trichloroacetic acid (TCA) as a technique minimally invasive. ⋯ Endoscopic management of congenital and recurrent TEF with the use of 50% TCA is as a minimally invasive, effective, simple and safe technique in these patients and avoids the morbidity of open surgery.
