Thoracoscopic vagotomy

BACKGROUND: Chronic cough is common after lobectomy. Vagus nerves are part of the cough reflex. Accordingly, transection of the pulmonary branches of vagus nerve may prevent chronic cough. And there are no clear recommendations on the management of the pulmonary branches of vagus in any thoracic surgery guidelines. METHODS: This is a single-center, randomized controlled trial. Adult patients undergoing elective video-assisted thoracoscopic lobectomy and lymphadenectomy were randomized at a 1:1 ratio to undergo a sham procedure (control group) or transection of the pulmonary branches of the vagus nerve that innervate the bronchial stump plus the caudal-most large pulmonary branch of the vagus nerve...

Marginal ulcer (MU) is a potential complication following Roux-en-Y gastric bypass (RYGB), with a mean prevalence of 4.6%. Early identification and prompt intervention are crucial to mitigating further complications. The pathophysiology of MU is complex and involves multiple factors, including smoking, Helicobacter pylori infection, non-steroidal anti-inflammatory drug (NSAID) use, and larger pouch size. Patients with MU may experience acute or chronic abdominal pain. Rarely, they may present with a complication from the ulceration, such as bleeding, perforation, or strictures...

A subset of patients with marginal ulcers after Roux-en-Y gastric bypass (RNYGB) is refractory to medical management. Here we report a retrospective review of a single institution cohort (N = 10) of video- or robotic-assisted thoracoscopic (VATS or RATS) truncal vagotomies performed between 2013 and 2018. All patients had recurrent marginal ulcers following RNYGB complicated by bleeding or perforation, refractory to medical management for a median of 3.5 months prior to undergoing truncal vagotomy. With a median of 23 months' follow-up, only three patients had continued symptoms (70% symptom resolution) post-operatively...

INTRODUCTION: Marginal ulcer is a common complication following Roux-en-Y gastric bypass with incidence rates between 1 and 16%. Most marginal ulcers resolve with medical management and lifestyle changes, but in the rare case of a non-healing marginal ulcer there are few treatment options. Revision of the gastrojejunal (GJ) anastomosis carries significant morbidity with complication rates ranging from 10 to 50%. Thoracoscopic truncal vagotomy (TTV) may be a safer alternative with decreased operative times...

BACKGROUND: Marginal ulcers (MUs) are potentially complex complications after Roux-en-Y gastric bypass. Although most resolve with medical management, some require surgical intervention. Many surgical options exist, but there is no standardized approach, and few reports of outcomes have been documented in the literature. The objective of this study was to determine the outcomes of surgical management of marginal ulcers. METHODS: Data from all patients who underwent surgical intervention between 2004 and 2012 for treatment of MU after previous Roux-en-Y gastric bypass were reviewed...

OBJECTIVES: This study evaluated the effect of high selective bilateral vagotomy of hilus pulmonis with video-assisted thoracoscopy on asthma. METHODS: Eight dogs with skin sensitive to Ascaris suum antigens were randomly divided into groups A and B. Asthma was induced by aerosol inhalation of A suum antigens. Respiratory rate and peak airway pressure were significantly increased (P < .05) in both groups. Dynamic compliance was dramatically increased (P < ...

Marginal ulcer is a significant complication of laparoscopic Roux-en-Y gastric bypass (LRYGB). Most marginal ulcers resolve with medical management, but nonhealing ulcers may require revision of the gastrojejunostomy, a procedure with significant morbidity and mortality. Traditionally, surgical therapy for refractory peptic ulcers includes a vagotomy. The current study evaluates the effectiveness of thoracoscopic truncal vagotomy (TTV) in the management of refractory marginal ulcers. All patients at two institutions with an intractable marginal ulcer after LRYGB treated with TTV between 2003 and 2010 were reviewed...

OBJECTIVES: The limited information available on thoracoscopic pulmonary vein isolation combined with ganglionated plexi ablation and the lack of studies regarding its effect on quality of life and physical capacity urged us to study its acute and long-term results in patients with atrial fibrillation. METHODS: Forty-three patients (mean age 57.1 years) with symptomatic atrial fibrillation referred for thoracoscopic off-pump epicardial pulmonary vein isolation and ganglionated plexi ablation using radiofrequency energy were included...

The present study stems from our recent demonstration (Moreau-Bussiere F, Samson N, St-Hilaire M, Reix P, Lafond JR, Nsegbe E, Praud JP. J Appl Physiol 102: 2149-2157, 2007) that a progressive increase in nasal intermittent positive pressure ventilation (nIPPV) leads to active glottal closure in nonsedated, newborn lambs. The aim of the study was to determine whether the mechanisms involved in this glottal narrowing during nIPPV originate from upper airway receptors and/or from bronchopulmonary receptors. Two groups of newborn lambs were chronically instrumented for polysomnographic recording: the first group of five lambs underwent a two-step bilateral thoracic vagotomy using video-assisted thoracoscopic surgery (bilateral vagotomy group), while the second group, composed of six lambs, underwent chronic laryngotracheal separation (isolated upper airway group)...

Various modalities for the treatment of hypertrophic pulmonary osteoarthropathy (HPOA) associated with lung cancer have been suggested since 1958. Although the etiology remains speculative, unilateral vagotomy on the side of the lung cancer achieves symptomatic relief. We report a case of a 50-year-old woman with disabling HPOA and inoperable lung cancer who experienced effective pain relief and regained full mobility after video-assisted thoracoscopic surgery was used to perform truncal vagotomy. This relatively safe and simple procedure should be considered for terminal lung cancer patients with intractable HPOA...

Aiming to minimize the surgical trauma and interventional risks of treatment, as well as to reach the most precise visualization and safe separation of the n. vagus, in order to increase the efficacy of truncal vagotomy during correction of severe post-gastric-resection dumping syndrome we have developed the new method of thoracoscopic supradiafragmal vagotomy. The suggested method of bilateral thoracoscopic supradiafragmal truncal vagotomy allows to decrease the surgical intervention trauma, and the risk of post operative complications, as well as to better the immediate and remote results of treatment of the dumping syndrome...

BACKGROUND: Evaluating the introduction of endoscopic surgery in Senegal may be useful for assessing the role of this technology in developing countries. METHODS: The endoscopic surgery performed at the Hospital Principal and the Hospital Le Dantec, Dakar, from January 1995 to December 2000 was evaluated retrospectively. Operative time, postoperative stay, patients, and hospital costs were compared in samples of 100 patients treated endoscopically and 80 patients treated with open techniques...
