Thoracotomy for esophageal leiomyomas. Preoperative, intraoperative, and postoperative care

Robotic-assisted enucleation of a large lower esophageal leiomyoma and review of literature

Leiomyoma is the most common benign esophageal neoplasm. Different invasive surgical approaches have been described for management of such lesions. The literature is reviewed and a robotic assisted left thoracoscopic enucleation with the patient in the right side position is described. A 40-year-old male patient, otherwise healthy, found to have a lower midiastinal mass on screening X-ray, is described. Physical examination and blood tests were within normal limits. Diagnostic work-up included: computerized tomography (CT) scanning of the chest and midiastinum that revealed a 40 × 30 mm mass of the distal esophagus, an upper gastrointestinal endoscopy showed a lower protruding esophageal submucosal mass with intact mucosa, a filling defect was apparent on esophagography. Endoscopic ultrasonography (EUS) showed the same findings, biopsies were taken and leimyoma was diagnosed. Under general anesthesia with a double-lumen endotracheal tube, the patient was positioned on his right side. A 30 robotic scope was introduced in the left 7th intercostal space on the posterior axillary line. Two 8-mm robotic trocars were inserted in the left 5th and 9th intercostals spaces on the same line. Operative field was clearly exposed and an additional 5-mm ethicon trocar was inserted. The inferior pulmonary ligament was released, the parietal pleural space opened, proximal and distal control was achieved using Penrose. The muscular layer of the lower esophagus was opened by coagulation hook, the lesion was enucleated without mucosal penetration. Intraoperative endoscopy permitted localization of the lesion and ensured mucosal integrity. The muscular layer was not closed and the chest drain was left. Total operative time was 200 min and blood loss was less than 20 mL. A Gastrograffin swallow on the first post-operative day showed good esophageal clearance and absence of leak, the patient was allowed a liquid diet. He was discharged on the third post-operative day in a good general condition, benign pathology was confirmed.

Robotic Fourth-Arm Enucleation of an Esophageal Leiomyoma and Review of Literature

Esophageal leiomyomas are resected in symptomatic and/or malignancy-suspicious cases. Traditionally, they have been removed by laparotomy or thoracotomy and more recently by thoracoscopy and laparoscopy. Mucosal injury is reported as high as 7% of cases but may be higher in unreported general practice. Robotic technology seems to offer advantages. We describe a robotic approach that seems to minimize mobilization of the esophagus, potentially decreasing the likelihood of mucosal injury and postoperative recovery time. We review the literature to evaluate the reports of mucosal injury with the open, minimally invasive, and robotic techniques and describe our own method. To improve efficiency, we use a four-arm technique.

Stomach tumors and gastric surgery

Malignant and benign tumors of the stomach must be resected. Some can be removed endoscopically, but larger lesions must be removed via traditional surgical methods. This article provides an overview of malignant and benign stomach tumors and outlines the determination of diagnosis and the recommended treatment. It describes different types of gastric surgery and the RN first assistant's role in these procedures. A case study of a rare type of benign stomach tumor also is presented.
