Abstract
BACKGROUND Transoral incisionless fundoplication (TIF) treats gastroesophageal reflux disease (GERD) by creating a full-thickness esophagogastric plication using transmural fasteners. If unsuccessful, revision laparoscopic anti-reflux surgery (rLARS) may be performed. This study evaluated operative findings and clinical outcomes of rLARS in 28 patients with prior primary TIF. METHODS Intraoperative findings, complications, and symptomatic outcomes with GERD health-related quality of life (GERD-HRQL) were evaluated prospectively in patients having rLARS after TIF. Results are median with interquartile range (IQR). RESULTS Between 03/2009 and 08/2013, 28 patients underwent rLARS at 14 (13-50) months post-TIF for recurrent symptoms after initial improvement. Pre-rLARS endoscopies found hiatal hernia (9) and wrap disruption (12). All revisions were completed laparoscopically in 88 (70-90) min. Eight patients underwent partial fundoplication, the rest Nissen. No intraoperative or postoperative complications occurred. Operative findings included: No axial hernia in 65%; Dense adhesions in 14%; Fasteners incorporating the lateral crus in 95%; Traction diverticuli from esophagus to crura in 21%. Residual plication was noted anteriorly in 75%, posteriorly in 0%. Operative approaches: (1) Areas where the TIF fundoplication remained were left intact. This necessitated rolling the fundoplication over the fused area to prevent an endoscopic appearance of 'fold'. (2) Fasteners were cut and left to migrate into the lumen, rather than being pulled out. (3) In 8 patients with fusion of the lateral crus to TIF fundoplication and no axial hernia, revision fundoplication was performed without mediastinal mobilization but with posterior hernia repair. One patient required subsequent surgery for small paraesophageal hernia, one for refractory gas-bloat after rLARS. Dysphagia in 2 patients resolved with dilation. GERD-HRQL improved from a median of 20 (8-27) pre-TIF and 10 (1-20) pre-rLARS to 3 (0-4) at 28 months (12-40) post-rLARS (p = 0.020 for pre-rLARS to post-rLARS). CONCLUSION rLARS after TIF can be performed safely with excellent clinical outcomes.

Abstract
BACKGROUND Fistulae between the tracheobronchial tree and the gastric conduit post-esophagectomy are a rare but sometimes fatal complication. Clinical presentation can range from asymptomatic to acute pulmonary decompensation. Traditional management options, such as esophageal exclusion alone or combined with transthoracic fistula division, and closure (with tissue interposition), are highly invasive, technically difficult, and associated with variable success rates. This video presents closure of highly complex, chronic esophagobronchial fistula (EBF) using simultaneous bronchoscopic and upper endoscopic techniques. METHODS Diagnostic bronchoscopy and upper endoscopy are performed to assess the size and location of fistulae. Fistulae with sufficient luminal size to accommodate a biologic plug were selected for treatment. Steps of EBF plug insertion. (1) Wire across fistula with ends exposed through the mouth. (2) Delivery sheath passed across wire from bronchial side to esophageal side (3) Plug loaded on the esophageal side of the sheath. (4) Plug pulled into position across the fistula from esophageal to bronchial side. (5) Delivery sheath released from bronchial side. RESULTS Two of four fistulae were suitable for plug therapy. A temporary covered-stent was placed to help maintain the plugs in place. Endoscopy at 1 month showed healing of the plugged fistula following stent removal. Respiratory symptoms were improved with no further episodes of pneumonia. Over course of 2 years, the patient has required three additional endoscopic procedures to control new fistulae from this broad area of exposed lung paranchyma, but the initial fistula plug repair is durable. CONCLUSION Post-esophagectomy fistula is a morbid complication and the surgical treatments available are highly morbid and have variable success rates. Due to the development of new endoscopic technologies, the endotherapy has assumed new prominence for treatment of enteric fistula. This complex case illustrates feasibility of endoscopic fistula treatment using dual scope, biologic plug application which effectively controlled this patient's EBF symptoms.

Abstract
POEM is an effective treatment of functional manometric esophageal outflow obstructive disorders with excellent relief of dysphagia. Reflux rates seem to be similar to that seen with traditional Heller myotomy with fundoplication. The POEM technique provides a true surgical esophageal myotomy without incisional pain. As such, POEM represents the first truly practical application of natural orifice surgery.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a very prevalent disorder. Medical therapy improves symptoms in some but not all patients. Antireflux surgery is an excellent option for patients with persistent symptoms such as regurgitation, as well as for those with complete symptomatic resolution on acid-suppressive therapy. However, proper patient selection is critical to achieve excellent outcomes. STUDY DESIGN A panel of experts was assembled to review data and personal experience with regard to appropriate preoperative evaluation for antireflux surgery and to construct an evidence and experience-based consensus that has practical application. RESULTS The presence of reflux symptoms alone is not sufficient to support a diagnosis of GERD before antireflux surgery. Esophageal objective testing is required to physiologically and anatomically evaluate the presence and severity of GERD in all patients being considered for surgical intervention. It is critical to document the presence of abnormal distal esophageal acid exposure, especially when antireflux surgery is considered, and reflux-related symptoms should be severe enough to outweigh the potential side effects of fundoplication. Each testing modality has a specific role in the diagnosis and workup of GERD, and no single test alone can provide the entire clinical picture. Results of testing are combined to document the presence and extent of the disease and assist in planning the operative approach. CONCLUSIONS Currently, upper endoscopy, barium esophagram, pH testing, and manometry are required for preoperative workup for antireflux surgery. Additional studies with long-term follow-up are required to evaluate the diagnostic and therapeutic benefit of new technologies, such as oropharyngeal pH testing, multichannel intraluminal impedance, and hypopharyngeal multichannel intraluminal impedance, in the context of patient selection for antireflux surgery.

Abstract
Esophageal adenocarcinoma is the most rapidly increasing gastrointestinal cancer. Barrett's esophagus has been identified as a precancerous condition and major risk factor for esophageal cancer. Radiofrequency ablation has been shown to be a highly efficient in promoting remission of intestinal metaplasia. This technology has seen widespread clinical use since 2005. Radiofrequency ablation is common with all other ablative techniques; the concern that sound oncological principles are not being adhered to, that is, appropriate pathological staging, followed by appropriate definitive therapy. Endoscopic mucosal excision techniques are technically demanding; however, they are more attractive from an oncological perspective. Future research endeavors focusing on facilitation of large population screening, the identification of high risk phenotypes, endoscopic mucosal resection techniques will combat the esophageal adenocarcinoma epidemic.

Abstract
OBJECTIVE The cultural desire to avoid cervical incisions and increasing concern for cosmetic outcomes has motivated surgeons to develop alternative approaches to thyroid surgery. The Direct Drive Endoscopic System (DDES) platform combines a flexible endoscope with a pair of separately controlled articulating instruments through a single, flexible, access system. We hypothesized that the DDES platform would permit single-incision minimally invasive thyroid lobectomy without robotic assistance. METHODS This is a single-cadaver feasibility study. A single, 2.2-cm subxyphoid incision was used for access. The platform's 55-cm flexible sheath was secured to the operating table rails and introduced into the subcutaneous space. A flexible pediatric endoscope was simultaneously introduced with 2 interchangeable 4-mm instruments. Blunt dissection and electrocautery were used to create the tunnel in the otherwise free central plane. The thyroid was dissected using a superior to inferior technique while maintaining the critical steps of traditional thyroid surgery. A Veress needle introduced through the lateral neck provided additional retraction. RESULTS The total operating time was 2.5 hours. The subcutaneous tunnel was safe and accommodated the DDES well. Visualization was adequate. Graspers, scissors, and hook cautery were used to complete the lobectomy. The ergonomics, articulation, and strength of the instrumentation were sufficient. CONCLUSIONS Subxyphoid thyroidectomy is technically possible and avoids the difficulties inherent to a transaxillary approach while still avoiding cosmetically unappealing cervical scars. Continued technological refinement will only expand the therapeutic possibilities of flexible endoscopy while minimizing the physical insult to patients and maximizing aesthetics for patients.

Abstract
BACKGROUND Per-oral endoscopic myotomy (POEM) requires advanced flexible endoscopic skills, especially in the management of complications. METHODS We present a full-thickness esophagotomy while performing POEM and repair using an endoscopic suturing device. STANDARD OPERATIVE TECHNIQUE An anterior esophageal 2 cm mucosectomy is created 7-10 cm proximal to the gastroesophageal junction after a submucosal wheal is raised. A submucosal tunnel is created and extended to 2 cm on the gastric cardia. A selective circular myotomy is performed. The mucosectomy is closed using endoscopic clips. CASE PRESENTATION An inadvertent full-thickness esophagotomy was created while performing the mucosotomy on an inadequate submucosal wheal. We were able to resume the POEM technique at the initial esophagotomy site. There was a discussion to convert to laparoscopy. However, as we succeeded in creating the tunnel, we continued with the POEM technique. After the selective myotomy was completed, we used an endoluminal suturing device (Overstitch, Apollo Endosurgery, Austin TX) to close the full-thickness esophagotomy in two layers (muscular, mucosal). A covered stent was not an option because the esophagus was dilated, which precluded adequate apposition. The patient had an uneventful postoperative course. At 9-month follow-up, had excellent palliation of dysphagia without reflux. CONCLUSIONS This case demonstrates the importance of identifying extramucosal intrathoracic anatomy, thus emphasizing the need for an experienced surgeon to perform these procedures, or at a minimum to be highly involved. Raising an adequate wheal is crucial before mucosectomy. Inadequacy of the wheal may reflect local esophageal fibrosis. If this fails at multiple locations in the esophagus, it may be prudent to convert to laparoscopy. This case also demonstrates the need for advanced flexible endoscopic therapeutic tools and a multidisciplinary approach to manage potential complications.

Abstract
OBJECTIVES To review transabdominal esophagocardiomyotomy (surgical treatment of achalasia) of the esophagus and to compare outcomes of partial anterior vs partial posterior fundoplication. DATA SOURCES An electronic search was conducted among studies published between January 1976 and September 2011 using the keywords achalasia, myotomy, antireflux surgery, and fundoplication. STUDY SELECTION Prospective studies of transabdominal esophagocardiomyotomy were selected. DATA EXTRACTION Outcomes selected were recurrent or persistent postoperative dysphagia and an abnormal 24-hour pH test result. Studies were divided into the following 3 groups: myotomy only, myotomy with anterior fundoplication, and myotomy with posterior fundoplication. Studies were weighted by the number of patients and by the follow-up duration. Event rates were calculated using meta-regression of the log-odds with the inverse variance method. DATA SYNTHESIS Thirty-nine studies with a total of 2998 patients were identified. The odds of postoperative dysphagia were 0.06 (95% CI, 0.03-0.12) for myotomy only, 0.11 (95% CI, 0.09-0.14) for myotomy with anterior fundoplication, and 0.06 (95% CI, 0.04-0.08) for myotomy with posterior fundoplication. The odds of a postoperative abnormal 24-hour pH test result were 0.37 (95% CI, 0.12-1.08) for myotomy only, 0.16 (95% CI, 0.11-0.24) for myotomy with anterior fundoplication, and 0.18 (95% CI, 0.13-0.25) for myotomy with posterior fundoplication. The increased odds of postoperative dysphagia in the group undergoing myotomy with anterior fundoplication compared with the group undergoing myotomy with posterior fundoplication were statistically significant (P < .001). However, the incidence of a postoperative abnormal 24-hour pH test result was statistically similar. CONCLUSION Partial posterior fundoplication when combined with an esophagocardiomyotomy may be associated with significantly lower reintervention rates for postoperative dysphagia, while providing similar reflux control compared with partial anterior fundoplication.

Abstract
OBJECTIVES To determine if laparoscopic colectomy is safer and more effective than open colectomy in patients older than 80 years of age. METHODS An operating room database of all colectomies performed on patients >or=80 years, from January 2002 to September 2007, was analyzed retrospectively. Data reviewed included type of operation, type of resection, length of procedure, length of stay (LOS), estimated blood loss, American Society of Anesthesiologists (ASA) grade, diagnosis, complications, mortality rates, and discharge destination, with p-values <0.05 considered significant. RESULTS One hundred thirty-nine patients underwent open procedures (Open group) during the study period versus 150 patients who underwent laparoscopic procedures (Lap group). Of the Lap group, 15 patients were converted to open cases. Forty-four patients from the Open group were excluded from the analysis as they were treated emergently, leaving 95 patients in the Open group. The mortality for open procedures was significantly higher at 9/95 (9.4%), compared with 3/150 (2%) following laparoscopic procedures (p = 0.0132). LOS was significantly longer for open procedures (11.16 days) versus laparoscopic procedures (7.11 days), p = 0.0001. Open procedures were associated with an increased risk of postoperative ileus (p < 0.02). The Open group had a higher likelihood of discharge to a nursing facility (43/87) than the Lap group (33/147), p < 0.0001. There were no significant differences in the length of procedure, estimated blood loss and postoperative complications. CONCLUSIONS Laparoscopic colectomy is a safer option that offers an improved outcome compared with open colectomy in elderly patients. Significant improvements in LOS, mortality rates, and discharge destination were observed.
