Mo1969 Per-Oral Endoscopic Tumor Resection for Submucosal Tumors of the Esophageal and Gastric Cardia

AbstractThe last decade has seen the growth of a completely new and exciting entity called the third space endoscopy (TSE) that has brought about a paradigm shift in the way we manage various disorders of the gastrointestinal tract. The journey started with per oral endoscopic myotomy (POEM) for achalasia cardia and within a decade the concept has been exploited to its best potential for disorders including submucosal tumor resection, pyloromyotomy for gastroparesis, complete division of septum without the risk of perforation in diverticular diseases of esophagus, restoration of esophageal lumen in long strictures, restoration of bowel movement in Hirschsprung’s disease, and then taking the concept to the next level of pure NOTES (natural orifice transluminal endoscopic surgery) by entering the peritoneal cavity and performing fundoplication. This review will discuss the history of TSE with brief discussion about the various applications and what has been achieved till present.

Endoscopic Tumor Resection

Introduction: Visual dysfunction is one of the primary indications for surgical management of pituitary tumors with the goal of terminating the progressive decline in vision. Unfortunately, it is difficult to predict how successful surgical decompression will be in these patients. The purpose of this study was to assess the structural changes seen in the anterior visual pathway after pituitary tumor resection. Methods: 13 patients (7F) underwent endoscopic tumor resection for pituitary macroadenoma. Each patient underwent a full ophthalmologic assessment including optical coherence tomography (OCT) preoperatively and postoperatively at 3-6months and 9-12months. Post-surgical changes in the retinal nerve fiber layer thickness (RNFLT) for each eye (N=26) were compared in cases with normal preoperative RNFLT (greater than 80 μm) versus those with abnormally thinned RNFLT (less than 80 μm). Results: For 9 cases with thinned RNFLT preoperatively (mean=70.1 μm±8.5), there was a significant decline in RNFLT at 3-6 months follow-up (mean change= −3.8 μm;p=0.002), which did not recover even at 9-12months after surgery (mean=67.6 μm±12.7). Contrastingly, eyes with normal RNFLT preoperatively (mean=89.7 μm±9.4) did not show significant postoperative thinning (mean change= −1.9 μm). Conclusion: Even after a complete surgical decompression, there are ongoing structural changes in the anterior visual pathway in patients with compressive neuropathy. There may be a point of no return where surgical decompression may not prevent further structural degeneration.

Endoscopic Tumor Resection

Cardiac myxoma is the most common benign cardiac tumor. Its tremendous size and fragile character severely bother the surgeons. Several minimal invasive approaches had been applied for radical tumor excision. The wound was forcibly enlarged for en-bloc specimen removal and prevention of debris sputtering. We reported a case of huge tricuspid valve (TV) myxoma managed by robot-assisted endoscopic tumor resection and TV repair. The tumor was downsized with a morcellator and removed through a keyhole wound (1.1 cm in diameter). The patient recovered uneventfully and was discharged after four days.
