684 - The Influence of Hospital Volume and Payor Status on 5-Year Outcomes in Patients Undergoing Laparoscopic vs Open Bilateral Inguinal Hernia Repair
New Disposable Transanal Endoscopic Surgery Platform: Longer Channel, Longer Reach
Abstract: Background: Transanal endoscopic surgical (TES) resection using rigid transanal platforms (TEM, TEO) is associated with improved outcomes compared to traditional transanal excision (TAE) of rectal lesions. An alternative technique using a disposable single incision surgery platform was developed in 2009, transanal minimally invasive surgery (TAMIS), resulting in a surge in interest and access to transanal access platforms to perform TES. However, compared to rigid transanal access platforms, the disposable platforms do not facilitate internal rectal retraction and have limited proximal reach. A new long channel disposable transanal access platform has been developed (15 cm in length, 4 cm in width) thereby facilitating endoluminal surgical access to the upper rectum and rectosigmoid colon. Methods: This is a retrospective case series report. Patient demographics and peri-operative outcome variables were recorded. The Gelpoint Path Long Channel was utilized in three patients with proximal rectal lesions that were not accessible using a standard disposable transanal access platform.Results: Three patients underwent TES excision of rectal adenomas using a long channel, disposable, transanal access platform. All patients were female, aged 51 – 53, BMI 23-32 kg/m2. The tumor size ranged from 2.4 – 8.5 cm, 15-100% circumference, and proximal location from the dentate line ranged from 9 – 11 cm. Final pathology revealed adenoma with negative margins in all three cases. The hospital length of stay ranged from 1 – 3 days and there were no perioperative complications. None of the patients have developed a local recurrence during the follow up period ranging from 5 – 11 months.Conclusions: The new long channel, disposable, transanal access platform facilitates transanal endoluminal surgical removal of lesions in the mid to upper rectum that may be difficult to reach using the standard disposable transanal access devices. We have successfully achieved 100% margin negative rate using this new device in this small series of patients with proximal rectal adenomas
607 Etamis: Transanal Minimally Invasive Surgical Submucosal Excision of a Large, Circumferential, Rectal Adenoma With Endoscopic Visualization
Intraoperative Endoscopic Botox Injection During Total Esophagectomy Prevents the Need for Pyloromyotomy or Dilatation
Background: Esophagectomy may lead to impairment in gastric emptying unless pyloric drainage is performed. Pyloric drainage may be technically challenging during minimally invasive esophagectomy and can add morbidity. We sought to determine the effectiveness of intraoperative endoscopic injection of botulinum toxin into the pylorus during robotic-assisted esophagectomy as an alternative to surgical pyloric drainage. Materials and Methods: We performed a retrospective analysis of patients with adenocarcinoma and squamous cell carcinoma of the distal esophagus or gastroesophageal junction who underwent robotic-assisted transhiatal esophagectomy (RATE) without any surgical pyloric drainage. Patients with and without intraoperative endoscopic injection of 200 units of botulinum toxin in 10 cc of saline (BOTOX group) were compared to those that did not receive any pyloric drainage (noBOTOX group). Main outcome measure was the incidence of postoperative pyloric stenosis; secondary outcomes included operative and oncologic parameters, length of stay (LOS), morbidity, and mortality. Results: From November 2006 to August 2014, 41 patients (6 females) with a mean age of 65 years underwent RATE without surgical drainage of the pylorus. There were 14 patients in the BOTOX group and 27 patients in the noBOTOX group. Mean operative time was not different between the comparison groups. There was one conversion to open surgery in the BOTOX group. No pyloric dysfunction occurred in the BOTOX group postoperatively, and eight stenoses in the noBOTOX group (30%) required endoscopic therapy (P<.05). There were no differences in incidence of anastomotic strictures or anastomotic leaks. One patient in group noBOTOX required pyloroplasty 3 months after esophagectomy. There was one death in the noBOTOX group postoperatively (30-day mortality 2.4%). Mean LOS was 9.6 days, and BOTOX patients were discharged earlier (7.4 versus 10.7, P<.05). Conclusion: Intraoperative endoscopic injection of botulinum toxin into the pylorus during RATE is feasible, safe, and effective and can prevent the need for pyloromyotomy
