Abstract
BACKGROUND METHODS The question prompt list content was derived through a modified Delphi process consisting of 3 rounds. In round 1, experts provided 5 answers to the prompts "What general questions should patients ask when given a new diagnosis of Barrett's esophagus" and "What questions do I not hear patients asking, but given my expertise, I believe they should be asking?" Questions were reviewed and categorized into themes. In round 2, experts rated questions on a 5-point Likert scale. In round 3, experts rerated questions modified or reduced after the previous rounds. Only questions rated as "essential" or "important" were included in Barrett's esophagus question prompt list (BE-QPL). To improve usability, questions were reduced to minimize redundancy and simplified to use language at an eighth-grade level (Fig. 1). RESULTS Twenty-one esophageal medical and surgical experts participated in both rounds (91% males; median age 52 years). The expert panel comprised of 33% esophagologists, 24% foregut surgeons, and 24% advanced endoscopists, with a median of 15 years in clinical practice. Most (81%), worked in an academic tertiary referral hospital. In this 3-round Delphi technique, 220 questions were proposed in round 1, 122 (55.5%) were accepted into the BE-QPL and reduced down to 76 questions (round 2), and 67 questions (round 3). These 67 questions reached a Flesch Reading Ease of 68.8, interpreted as easily understood by 13 to 15 years olds. CONCLUSIONS With multidisciplinary input, we have developed a physician-derived BE-QPL to optimize patient-physician communication. Future directions will seek patient feedback to distill the questions further to a smaller number and then assess their usability.

Abstract
AIMS The increased use of endoscopy as a minimally invasive therapeutic technique has created a great demand for endoscopic training. The Basic Endoscopic Skills Training (BEST) box provides a low-cost solution by adapting the Fundamentals of Laparoscopic Surgery (FLS) box for flexible endoscopic simulation. The BEST box consists of six endoscopic tasks with a 5-min time limit per task. This study aims to develop a scoring system for objective evaluation of user performance. METHODS A total of 165 participants were tested on the BEST box. Participants were divided into two groups: retrospective analysis (n = 100) and prospective analysis (n = 65). From the retrospective group, 55 individuals were also scored on the Global Assessment of Gastrointestinal Endoscopic Skills-Upper Endoscopy (GAGES-UE). Linear regression between user performance on BEST box and GAGES-UE was performed to develop the scoring system. Receiver Operating Characteristic curve was used to determine a threshold score to help users appreciate their endoscopic expertise. Prospective scoring of 65 individuals was then performed using the formula developed (20 experts and 45 trainees). RESULTS The minimum and maximum possible scores are 30 and 110, respectively. Retrospective analysis showed that the scoring system was able to distinguish between experts and trainees (p < 0.001), correlated with GAGES-UE (p < 0.001), and had a reliability constant of r = 0.765 (p < 0.001). On prospective testing using the scoring system the expert group received a final average score of 92, whereas the average score for the trainee group was 61 (p < 0.001). CONCLUSIONS The developed BEST box scoring system correlates with the experience level of the test taker as well as with the GAGES-UE scoring system. The results of this study add further evidence to the validity of the BEST box as an effective, low-cost endoscopic simulator with the scores used by trainees to track their performance level overtime.

Abstract
INTRODUCTION Laparoscopic paraesophageal hernia (PEH) is associated with a low morbidity and mortality but an objective hernia recurrence rate in excess of 50% at 5 years. Biologic mesh has not been shown to reduce hernia recurrence rates. Recently, a new bioresorbable mesh made with poly-4-hydroxybutyrate with a Sepra-Technology coating on one side (Phasix-ST mesh) has become available. The aim of this study was to evaluate the feasibility, safety, and short-term efficacy of Phasix-ST mesh for reinforcement of the primary crural closure in patients undergoing elective, laparoscopic PEH repair. METHODS A prospective database was initiated and maintained for all patients undergoing PEH repair with the use of Phasix-ST mesh. We retrospectively reviewed the records of consecutive patients who had an elective, first-time laparoscopic PEH repair with Phasix-ST mesh and who completed their 1-year objective follow-up study. Patients having a reoperation, non-laparoscopic repair, or who failed to comply with the objective follow-up were excluded. RESULTS To achieve the desired 50 patients with 1-year objective follow-up, we reviewed the records of 90 consecutive PEH patients. In the final cohort of 50 patients, there were 32 females (64%) and 18 males. The median age of the patients at surgery was 67 years (range 44-84). The operation was PEH repair with fundoplication alone in 29 patients (58%) and PEH repair with Collis gastroplasty and fundoplication in 21 patients (42%). Phasix-ST mesh was used for crural reinforcement in all patients, and there were no intraoperative issues with the mesh or any difficulty placing or fixating the mesh at the hiatus. A diaphragm relaxing incision was performed in 2 patients (4%). The mean length of hospital stay was 2.8 days, and there was no major morbidity or mortality. On the 1-year objective follow-up study (median 12 months) a recurrent hernia was found in 4 patients (8%). No patient that had a Collis gastroplasty or a relaxing incision had a recurrent hernia. No patient had a reoperation. No patient had a mesh infection or mesh erosion. CONCLUSIONS Phasix-ST mesh reinforcement of the crural closure during laparoscopic primary, elective PEH repair was associated with no adverse mesh-related events such as infection or erosion. Phasix-ST crural reinforcement in combination with tension-reduction techniques when necessary resulted in a very low (8%) objective hernia recurrence rate at a median follow-up of 1 year. These results demonstrate the safety of Phasix-ST mesh for use at the hiatus for crural reinforcement. This safety, along with the encouraging short-term efficacy for reducing hernia recurrence, should encourage further studies using the combination of resorbable biosynthetic mesh crural reinforcement and tension-reducing techniques during repair of paraesophageal hernias.

Abstract
BACKGROUND Cost-effectiveness of robotic-assisted surgery is still debatable. Robotic-assisted inguinal hernia repair has no clear clinical benefit over laparoscopic repair. We performed a comprehensive cost-analysis comparison between the two approaches for evaluation of their cost-effectiveness in a large healthcare system in the Western United States. METHODS Health records in 32 hospitals were queried for procedural costs of inguinal hernia repairs between January 2015 and March 2017. Elective robotic-assisted or laparoscopic unilateral inguinal hernia repairs were included. Cost calculations were done using a utilization-based costing model. Total cost included: fixed cost, which comprises medical device and personnel costs, and variable cost, which comprises disposables and reusable instruments costs. Other outcome measures were length of stay (LOS), conversion to open, and operative times. Statistics were done using t test for continuous variables and χ2 test for categorical variables. A p-value < 0.05 was considered significant. RESULTS A total of 2405 cases, 734 robotic-assisted (633 Primary: 101 recurrent) and 1671 laparoscopic (1471 Primary: 200 recurrent), were included. The average total cost was significantly higher (p < 0.001) in the robotic-assisted group ($5517) compared to the laparoscopic group ($3269). However, the average laparoscopic variable cost ($1105) was significantly higher (p < 0.001) than the robotic-assisted cost ($933). Whereas there was no significant difference between the two groups for LOS and conversion to open, average operative times were significantly higher in the robotic-assisted group (p < 0.001). Subgroup analysis for primary and recurrent inguinal hernias matched the overall results. CONCLUSIONS Robotic-assisted inguinal hernia repair has a significantly higher cost and significantly longer operative times, compared to the laparoscopic approach. The study has shown that only fixed cost contributes to the cost difference between the two approaches. Medical device cost plus the longer operative times are the main factors driving the cost difference. Laparoscopic unilateral inguinal hernia repair is more cost-effective compared to a robotic-assisted approach.

Abstract
Peroral endoscopic myotomy (POEM) is an advanced endoscopic procedure classically performed for the treatment of achalasia. The procedure is based on principles of submucosal endoscopy and is composed of a mucosal incision, submucosal tunneling, myotomy, and mucosal closure. Multiple published studies that collectively include more than 6000 patients reported clinical success in more than 80% to 90% of patients. Recent literature also suggested durability of response over a medium-term follow-up. POEM is associated with a low rate of adverse events when performed by experienced operators. Gastroesophageal reflux is not infrequent after POEM but does not seem significantly different from reflux that occurs after Heller myotomy. POEM also seems to be effective in the treatment of spastic esophageal disorders (eg, jackhammer and diffuse esophageal spasm). Last, the role of gastric POEM (G-POEM) in the treatment of gastroparesis has been investigated in recent studies with promising results.

Abstract
BACKGROUND Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that originate from the submucosa of the cervical esophagus [Owens et al. (JAMA 103: 838-842, 1994), Totten et al. (JAMA 25:606-622, 1953)]. Due to their indolent course, these tumors tend to reach enormous proportions before patients develop symptoms. Accurately diagnosing these tumors is difficult, as endoscopy may miss 25% of these lesions because these polyps exhibit normal intact esophageal mucosa [Levine et al. (JAMA 166: 781-787, 1996)]. METHODS Surgical resection has been the treatment of choice. We present a video that illustrates the feasibility of an endoscopic approach. TECHNIQUE/CASE A 62-year-old man presented to our clinic with a pedunculated esophageal mass. During this time, he developed progressive dysphagia to solid foods. A complete workup confirmed the presence of a giant polyp and endoscopic resection under general anesthesia was planned. Using an endoscopic snare-technique, a 16 cm × 3 cm polyp was amputated and retracted out of the oropharynx. Upon repeat endoscopy a second 7 cm × 3 cm polyp was discovered originating proximal to the larger polyp. Again, removal of this polyp was attempted using a snare-technique. Following amputation of the polyp, a broad-based component of the polyp remained. Given its proximal location in the esophagus, we were able to use a snare to pull the broad base of the remaining polyp into the oropharynx and remove it at its origin. Postoperative endoscopy and endoscopic ultrasound confirmed that the polyps were completely removed and the muscular resection bed was hemostatic. Clinically, the patient's symptoms resolved and he encountered no adverse sequela as a result of the operation. CONCLUSION Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that can lead to obstructive symptoms. Surgical resection is the treatment of choice, and may be possible with an endoscopic approach. An endoscopic snare technique can be used to resect these lesions while minimizing patient morbidity.

Abstract
BACKGROUND Laparoscopic surgery for gastrointestinal reflux disease was introduced in 1991. Early safety, efficacy, and 5-10-year durability have been amply documented, but long-term patient outcomes have been criticized. This study presents 20-year outcomes after laparoscopic fundoplication (LF) in a consecutive patient cohort. METHODS Patients who underwent primary LF procedures for gastroesophageal reflux disease (GERD) were identified from a prospectively collected IRB-approved database (1991-1995). A phone symptom questionnaire was administered using a 5-point validated GERD scoring system (heartburn, regurgitation, and dysphagia). Symptomatic success was defined by a lack of surgical re-intervention and a low symptom score. RESULTS One-hundred and ninety-three patients were identified during the time period. Fifty-one patients completed the survey (100 lost to follow-up, 40 deceased, 2 declined to answer). Respondents had a median follow-up of 19.7 years. Overall, 38/51 (74.5%) of patients reported complete control of heartburn and regurgitation. Ten patients reported only occasional heartburn. Eight of fifty-one (16%) reported daily dysphagia, and 22/51 (43%) of respondents were using proton pump inhibitors at the time of telephone interview. Nine of fifty-one (18%) underwent revision of the original surgery which did not negatively impact the satisfaction rating, with 8/9 (89%) of these patients reporting the highest satisfaction rating. Overall, 46/51 (90%) were satisfied with their choice of surgery. CONCLUSION Long-term results from the early experience with LF are excellent with 94% of patients reporting only occasional or fewer reflux symptoms at 20-year follow-up. However, 18% required surgical revision surgery to maintain their results. There is a relatively high rate of daily dysphagia but 90% of patients are happy to have had LF.

Abstract
Per-oral endoscopic myotomy (POEM) is a new minimally invasive endoscopic treatment for achalasia. Since the first modern human cases were published in 2008, around 2,000 cases have been performed worldwide. This technique requires advanced endoscopic skills and a learning curve of at least 20 cases. POEM is highly successful with over 90 % improvement in dysphagia while offering patients the advantage of a low impact endoscopic access. The main long-term complication is gastroesophageal reflux (GER) with an estimated incidence of 35 %, similar to the incidence of GER post-laparoscopic Heller with fundoplication. Although POEM represents a paradigm shift in the treatment of achalasia, more long-term data are clearly needed to further define its role in the treatment algorithm of this rare disease.

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
This paper includes commentaries on outcomes of esophageal surgery, including the mechanisms by which fundoduplication improves lower esophageal sphincter (LES) pressure; the efficacy of the Linx™ management system in improving LES function; the utility of radiologic characterization of antireflux valves following surgery; the correlation between endoscopic findings and reported symptoms following antireflux surgery; the links between laparoscopic sleeve gastrectomy and decreased LES pressure, endoscopic esophagitis, and gastroesophageal reflux disease (GERD); the less favorable outcomes following fundoduplication among obese patients; the application of bioprosthetic meshes to reinforce hiatal repair and decrease the incidence of paraesophageal hernia; the efficacy of endoluminal antireflux procedures, and the limited efficacy of revisional antireflux operations, underscoring the importance of good primary surgery and diligent work-up to prevent the necessity of revisional procedures.

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
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 AND STUDY AIMS Gastrointestinal stents have become an important therapeutic option for several indications. However, migration in up to 40 % of cases represents a significant drawback, especially when covered prostheses are used. We hypothesized that a novel endoscopic suturing device could enable endoluminal stent fixation, which might increase attachment and thereby potentially reduce migration. PATIENTS AND METHODS In an initial ex vivo porcine model, stents were attached to the esophageal wall with either endoscopic hemoclips or by endoscopic suture stent fixation (ESSF). The distal tension force required to induce dislocation was measured in Newtons (N) by a digital force gauge and was compared with conventional stent placement. ESSF was then performed clinically in five patients, in whom self-expanding metal stents were sutured in place for endoscopic treatment of gastrointestinal fistulas or strictures. RESULTS Esophageal ESSF was achieved in all experiments and significantly increased the force needed to displace the stent (n = 12; mean force 20.4 N; 95 % confidence interval [CI]: 15.4 - 25.4; P < 0.01) compared with clip fixation (n = 8; mean 6.1 N; 95 %CI 4.7 - 7.6) or stent placement without fixation (n = 16; mean 4.8 N; 95 %CI 4.0 - 5.6). All clinical cases of ESSF were performed successfully (5 /5) and took a median of 15 minutes. Elective stent removal was achieved without complications. One stent migration (1 /5) due to sutures being placed too superficially was observed. More loosely tied sutures remained intact, with the stent attached in place. CONCLUSION Endoscopic suture fixation of gastrointestinal stents provided significantly enhanced migration resistance in an ex vivo setting. In addition, early clinical experience found ESSF to be technically feasible and easy to accomplish.

Abstract
BACKGROUND Laparoscopic Hill repair (LHR) and laparoscopic Nissen fundoplication (LNF) are established surgical antireflux procedures but have never been compared in a prospective trial. This trial was designed to compare the effectiveness of LHR against the gold-standard LNF. METHODS Patients with uncomplicated gastroesophageal reflux from two esophageal centers were randomly assigned and blinded from 2003 to 2007. Preoperative and postoperative evaluation included two quality of life metrics--Quality of Life in Reflux and Dyspepsia, and Dysphagia--as well as endoscopy, video esophogram, manometry, and pH testing. RESULTS Of 121 patients who consented to the trial, 102 underwent surgery; 46 LNF and 56 LHR were performed, with a mean follow-up of 12 months. Postoperatively, the DeMeester score normalized for both repairs, with no difference between them (LNF 6.8, LHR 11.1, p=0.26). Postoperative medication use was 4%, and the groups were equivalent. Lower esophageal sphincter pressure increased significantly for LNF (14.93 to 24.10, p=0.001) but not for LHR (19.91 to 20.25, p=0.87). Quality of life scores improved significantly for both repairs (LNF 3.77 to 6.65; LHR 3.84 to 6.54, p<0.001), and postoperative results were equivalent (p=0.99). Dysphagia scores preoperative/postoperative were LNF 33.88 to 38.33 and LHR 35.44 to 38.72, and were equivalent postoperatively (p=0.94). Two LNF and two LHR required reoperation for failed repair. CONCLUSIONS The LHR and the LNF both yield excellent and equivalent results for uncomplicated gastroesophageal reflux at 12 months. Their mechanisms of action may be different.

Abstract
OBJECTIVE We recently reported in a multi-institutional, randomized study of laparoscopic paraesophageal hernia repair (LPEHR) that the anatomic recurrence rate at a median of approximately 5 years was >50%. This study focuses exclusively on the symptomatic response to LPEHR and its relationship with the development of a recurrent hernia. METHODS During 2002 to 2005, 108 patients underwent LPHER with or without biologic mesh. A standardized symptom severity questionnaire, SF-36 health survey, and upper gastrointestinal series were performed at baseline, 6 months, and during 2008-2009. RESULTS Of 108 patients, 72 (average age of 68 ± 10 years) underwent clinical assessment, and 60 of them also had radiologic studies at a median follow-up of 58 (40-78) months. Radiographic recurrence (≥ 20 mm) was 14% at 6 months and 57% at the time of follow-up, and the average recurrence size was 40 ± 10 mm. All symptoms were significantly improved at long-term follow-up and, with the exception of heartburn, were unaffected by the presence or size of the recurrence. Two patients (3%) with recurrent symptoms related to their hernia underwent reoperation. CONCLUSION Despite frequent radiologic recurrences after LPEHR, symptoms remain well controlled, patient satisfaction is high, and the need for reoperation is low.

Abstract
BACKGROUND A transrectal (TR) approach for natural orifice translumenal endoscopic surgery (NOTES) makes sense for colorectal surgery because the colotomy can be incorporated into subsequent anastomosis. Because cancer is a primary indication for left-sided colon resection, oncologic standards will have to be met by a NOTES procedure. This study aimed to assess whether pure TR rectosigmoidectomy can be performed with strict adherence to oncologic principles compared with a conventional laparoscopically assisted approach (LAP). METHODS Human male cadavers were allocated to either TR (n = 4) or LAP (n = 2). A simulated sigmoid lesion was created at 25 cm. Transrectal retrograde mobilization of the rectosigmoid was performed using conventional transanal endoscopic microsurgery (TEM) instrumentation. After ligation of the superior hemorrhoidal artery and further mobilization, the specimen was delivered transanally and divided extracorporeally. Using a circular stapler, NOTES colorectal anastomosis was performed. Lymph node yield, adequate resection margins, and operative time were compared with LAP. RESULTS Transrectal retrograde rectosigmoid dissection was achieved in all attempts (4/4) and showed numbers of lymph nodes (median, 5; range, 3-6) similar to the LAP group (median, 4.5; range, 2-7). One pure TR approach failed to resect the lesion. Three TR procedures required additional mobilization via an abdominal approach to provide adequate margins. The mean length of TR specimens was 16 ± 4 cm compared with 31 ± 9 cm achieved by LAP (p < 0.01). The TR operative time was significantly longer (247 ± 15 vs 110 ± 14 min). CONCLUSION Lymph node yield during TR rectosigmoidectomy was similar to that achieved by the LAP approach. However, conventional TEM instrumentation alone did not permit adequate colon mobilization. This indicates a need for flexible instrumentation or other technical solutions to perform true NOTES colectomies.

Abstract
BACKGROUND Despite trends toward regionalization of care, the majority of pancreaticoduodenectomies (PD) are performed in community hospitals by surgeons with varying degrees of experience. We analyzed the impact of several variables, including surgeon volume, on outcomes following PD within a high-volume community-based teaching hospital system. METHODS Patients who underwent PD from 2005 to 2008 were reviewed retrospectively. Perioperative data, complications, and hospital financial data was queried. A high-volume (HV) surgeon was defined as an average of 10 or more PD per year. RESULTS Ninety-four patients underwent PD with an overall operative mortality rate of 9.6% (HV 2.2%, LV 16.0%), major complication rate of 32% (HV 18%, LV 44%), and median cost of $30,860 (HV $27,185, LV $33,007). Factors predictive of death were age (p < 0.02), body mass index (p < 0.01), and surgeon volume (p < 0.05). Factors predictive of major complication were surgeon volume (p < 0.01) and body mass index (p < 0.01). Factors predictive for increased length of stay for patients discharged from the hospital were surgeon volume (p < 0.02) and preoperative ASA classification (p < 0.05). CONCLUSIONS Surgeon volume and patient body mass index have a significant impact on perioperative morbidity following PD in a community teaching hospital.

Abstract
Natural orifice transluminal endoscopic surgery (NOTES) is a new concept that attempts to reduce the impact of surgery on the patient. In surgical oncology several studies have already revealed that a minimally invasive approach provides at least the same, if not a better, long-term outcome. One could hypothesize that a less invasive approach such as NOTES could further enhance such advantages. Since its initial description, NOTES has become clinical reality and today nearly every organ is accessible by a transluminal approach, in at least the experimental setting. Subsequent to published research, first clinical studies on NOTES in oncology were reported and the accuracy of transgastric peritoneoscopy for staging of pancreas cancer was shown to be similar to laparoscopy in humans. A NOTES gastro-jejunostomy via transgastric access has also been proposed to decrease invasiveness of palliative treatment of duodenal, biliary and pancreatic cancers. Colorectal cancer resection via transanal access would offer a clear-cut patient advantage over laparoscopic and would not be subject to the frequent criticism of violating an innocent second organ, as the colon or rectum is always breached in a colectomy. Natural orifice endoluminal therapies, such as endoscopic submucosal dissection, already have been clinically applied for several years. Improved techniques or instruments evolving from NOTES technology might enhance its widespread use for the treatment of early malignancies and thereby again will provide a tremendous benefit for the patient. Although still somewhat controversial, the subject of natural orifice surgery in oncological disease indicates that current laboratory efforts to introduce NOTES into cancer surgery could be ready for cautious clinical investigations. The final determination of patient benefit will need well-constructed prospective study.

Abstract
BACKGROUND Recommended procedure numbers for upper endoscopy (UE) and colonoscopy (C) are 35 and 50 for surgical residents, and 130 and 140 for gastroenterology fellows, respectively. The purpose of this study was to challenge the methods used to determine proficiency in flexible endoscopy. METHODS Global assessment of gastrointestinal endoscopic skills (GAGES) was used to evaluate 139 procedures. Scores for UE were compared using self-reported case numbers and grouped according to requirements for each discipline. C scores were compared using the requirements to define novice and experienced endoscopists. Procedure volumes were plotted against GAGES scores. RESULTS Three groups were compared for UE based on case volumes: fewer than 35 cases (group 1), 35 to 130 cases (group 2), and more than 130 cases (group 3). There was no difference between group 2 (17.8 +/- 1.8) and group 3 (19.1 +/- 1.1), but both scored higher than group 1 (14.4 +/- 3.7; P < .05). For C, the scores were 11.8 +/- 3.8 (novices) and 18.8 +/- 1.34 (experienced; P < .001) at a 50-case minimum and 12.4 +/- 4.2 and 18.8 +/- 1.3 (P < .001) for a 140-case proficiency cut-off level, respectively. The curve of procedures versus GAGES plateaued at 50 (UE) and 75 (C). CONCLUSIONS The surgical and gastroenterology case recommendations may not represent the experience needed to achieve proficiency. GAGES scores could help define proficiency in basic endoscopy.
