RESUMO
BACKGROUND: Venous thromboembolism (VTE) occurs in 3-11% of esophagectomy patients and is associated with increased mortality and morbidity. The use of validated VTE risk assessment tools and compliance with recommended practice guidelines remains unclear. In this study, we seek to determine the use of Caprini guideline indicated VTE prophylaxis and its effect on VTE and bleeding complications following esophagectomy. METHODS: Esophagectomy cases were identified from the Mayo Clinic electronic health records. Caprini score and VTE prophylaxis regimen received were determined retrospectively. VTE prophylaxis was identified as appropriate or inappropriate based on the Caprini score and prophylaxis received preoperative, during hospitalization, and after hospital discharge. Study cohorts were compared by Pearson Chi-square test, Fisher's Exact test, Kruskal-Wallis test, and logistic regression models. Stata/MP 16.1 was used for analysis. Odds ratios and 95% confidence intervals were reported for logistic regression models. A p-value < 0.05 was considered significant. RESULTS: Four hundred and fifty-six esophagectomy cases were analyzed. The median Caprini score was thirteen. Appropriate prophylaxis resulted in a 6.9-fold reduction in inpatient VTE. All 30- and 90-day post-discharge VTEs occurred in those not receiving Caprini guideline-indicated VTE prophylaxis. Inpatient, 30- and 90-day post-discharge bleeding rates were 7.68%, 0.91%, and 2.11%, respectively; however, bleeding was not increased with receipt of appropriate prophylaxis. CONCLUSION: In this esophagectomy cohort, Caprini guideline indicated VTE prophylaxis resulted in reduced inpatient VTE events without increasing bleeding complications. Risk-based VTE prevention measures should be considered in this patient cohort known to be at heightened risk for postoperative VTE.

INTRODUCTION: Different techniques have been proposed for reoperation after failed anti-reflux surgery. However, there is no consensus on which should be preferred. We aim to report and compare the outcomes of different revisional techniques for failed anti-reflux surgery. METHODS: We performed a retrospective analysis of patients who underwent redo fundoplication (RF) or Roux-en-Y gastric bypass (RYGB) conversion after a failed fundoplication at our institution between 2016 and 2021. The primary outcome was long-term presence of reflux or dysphagia following revisional surgery. Secondary outcomes included 30-day perioperative complications as well as long-term use of anti-reflux medication and radiographic recurrence of hiatal hernia (HH). RESULTS: A total of 165 (median age 63 years, 73.9% female) patients were included. RF was performed in 120 (73 Toupet and 47 Nissen), RYGB in 38, and 7 patients had fundoplication takedown alone. The RYGB group had a significantly higher BMI, and more prior revisional surgeries compared to the other groups. Median operative time and length of stay were longer for RYGB. Twenty (12.1%) patients experienced postoperative complications, with the highest incidence in the RYGB group. Reflux and dysphagia improved significantly for the whole cohort, with the greatest improvement noted with reflux in the RYGB group (89.5% with preoperative reflux vs. 10.5% with postoperative reflux, p = < .001). On multivariable regression we found that prior re-operative surgery was associated with persistent reflux and dysphagia, whereas RYGB conversion was protective against reflux. CONCLUSION: Conversion to RYGB may offer superior resolution of reflux than RF, especially for obese patients.

Background: Enhanced recovery after surgery (ERAS) pathways focus on decreasing surgical stress and promoting return to normal function for patients undergoing surgical procedures. The aim of our study was to evaluate the impact of an ERAS protocol on outcomes of patients undergoing primary sleeve gastrectomy and Roux-en-Y gastric bypass. Outcomes included hospital length of stay (LOS), and management of postoperative pain and postoperative nausea and vomiting (PONV) measured by pain medications and antiemetic use, respectively. Incidence of 90-day emergency department (ED) visits, readmissions, and complications were also analyzed. Methods: A retrospective review was performed from October 1, 2016 to October 31, 2018 of patients enrolled in the ERAS versus the conventional pathway. Patient baseline characteristics, pain and nausea scores, LOS, and postoperative outcome variables were collected. Results: Non-ERAS (n = 193) and ERAS (n = 173) groups had similar patient characteristics. Fewer ERAS patients required postoperative opioids and antiemetics (P < .01), with a significant difference in postoperative nausea control in favor of ERAS patients (P < .05). There was a decreasing trend in median LOS (2 versus 1, P = .28), 90-day postoperative readmissions (10.4% versus 8.1%, P = .47), and major adverse events (5.2% versus 1.7%, P = .07) after ERAS implementation. The ED visits and postoperative need for intravenous fluid for dehydration were significantly lower in the ERAS group (P = .01). Conclusion: Implementation of ERAS pathway for bariatric surgery was associated with less opioid usage, PONV, ED visits, and postoperative need for intravenous fluids, without increasing LOS, 90-day readmission or rates of adverse effects.

Cancer arising in lichen planus of the esophagus (LPE) is extremely rare. We report 2 elderly female patients with LPE who developed squamous cell carcinoma. Both underwent laparoscopic ischemic gastric preconditioning followed 2 weeks later by 3-field esophagectomy. Final pathological stages were carcinoma in situ and pT3N2, respectively. No adjuvant therapy was given. The patient with in situ cancer has no evidence of recurrence at 24 months. The second patient opted to follow up locally and died 8 months later. LPE should be closely monitored for malignant degeneration. Esophagectomy should be considered when malignancy is detected.

BACKGROUND: The respiratory coefficient (RQ), as determined by indirect calorimetry (IC), classifies diet as being carbohydrate rich (RQ = 0.7-0.8), fat rich (RQ = 0.9-1.0), or overfeeding (RQ > 1). We hypothesized that preoperative RQ may be associated with weight-loss outcomes after bariatric surgery. METHODS: From 2016 to 2018, 137 obese patients were enrolled in a Bariatric Registry and underwent dietary and behavioral counseling, followed by preoperative IC. Resting energy expenditure (REE) and RQ of all patients was measured. Patients were classified as over-feeders (OF; 42, 31%) with RQ > 1 or non-over-feeders (NOF; 95, 69%) with RQ < 1. At baseline, there was no difference between groups in gender [female: 105 (76.6%), male: 32 (23.4%)], body mass index (BMI; OF: 46.8 ± 7.8 vs. NOF: 44.8 ± 7.4 kg/m2, p = 0.40), or baseline REE (OF: 1897 ± 622 vs. NOF: 1874 ± 579, p = 0.74), although OF were younger [mean age (OF: 47.1 ± 13.0 years vs. NOF: 43.1 ± 13.4; p = 0.009). At 6-month follow-up 94 patients [53.28%; OF: 35 (83%) vs. NOF: 59 (62%), p = 0.016] were seen and 48 [35.03%; OF: 23 (55%) vs. NOF: 25 (59%), p = 0.001] at 12-month follow-up. On preoperative psychological assessment, OF had a significantly higher rate of childhood neglect (OF: 28 (47.46%) vs. NOF: 40 (28.99%); p = 0.01). RESULTS: At 1 year postoperatively, the OF had a significantly higher BMI (OF: 34.3 ± 6.5 vs. NOF: 29.3 ± 5.1 kg/m2, p = 0.009). Differences in weight were not significant at 6-month (OF: 36.0 ± 6.5 vs. NOF: 33.5 ± 5.9 kg/m2, p = 0.07). There was no difference between type of operation and RQ group (RYGB; OF: 55 (75%) vs. NOF: 18 (25%) and SG; OF: 40 (62%) vs. NOF: 24 (38%), p = 0.14), nor in BMI loss after operation. CONCLUSION: Evidence of overfeeding in the preoperative period prior to bariatric surgery is associated with higher resultant BMI at 1 year. Calculation of the RQ with IC has prognostic significance in bariatric surgery, and calculation of REE based on assumed normal RQ potentiates error. It is unclear if overfeeding is purely behavioral or secondary to potentially reversible metabolic etiology.

INTRODUCTION: Laparoscopic magnetic sphincter augmentation (MSA) has been shown to be efficacious therapy for gastroesophageal reflux disease (GERD) refractory to maximal medical management. Herein, we present our experience with this procedure and an analysis of our outcomes. MATERIALS AND METHODS: Medical records were retrospectively reviewed of 98 patients who underwent laparoscopic MSA for GERD at a single institution from 2012 to 2016. Symptoms were assessed with gastroesophageal reflux disease-health-related quality of life (GERD-HRQL) questionnaire. Objective testing included pH testing, manometry, endoscopy, and upper GI series. Postimplantation interventions were recorded. Median follow-up was 46 months. RESULTS: Median preoperative DeMeester score was 32 (interquartile range 21-46). Esophagitis was present in 18%. Hiatal hernia was present in 59%. Operation required full hiatal dissection in 16%. There were no intraoperative complications. Mean hospital stay postimplantation was 18 hours. Reoperative intervention with device explant was necessary in 5 cases, one of which was for intraluminal device erosion. Median GERD-HRQL scores were 25 preoperatively, 8 in short-term follow-up at median 1 month, and 5 in long-term follow-up at median 46 months. Improvement in GERD-HRQL scores was statistically significant with both short and long term compared with preoperative (P < .05), but no different between short- and long-term follow-up. Daily bothersome dysphagia was present in 19 patients preoperatively and in 9 at long-term follow-up. CONCLUSIONS: Laparoscopic MSA is associated with excellent outcomes with decrease in GERD-HRQL scores in short term that are durable to longer term follow-up, and with low rates of new-onset dysphagia.

BACKGROUND: Outcomes are not well studied in patients undergoing remediation for multi-fundoplication failure, that is, two or more prior failed fundoplications. Re-operation must balance reflux control and restoration of the ability to eat with the challenge of reconstructing a distorted hiatus and GE junction. The purpose of this study is to present our experience with surgical remediation for multi-fundoplication failure. METHODS: Medical records were retrospectively reviewed of 91 patients who underwent third time or more esophagogastric operation for fundoplication failure at a single institution from 2007 to 2016. Dysphagia was present in 56% and heartburn in 51%. Median number of prior operations was 2 with range up to 6. Anatomic failure consisted of slipped wrap in 26 cases, wrap herniation in 23, hiatal stenosis in 24, hiatal mesh complication in 8, and wrap dehiscence in 10. Operative approaches generally followed an institutional algorithm and consisted of hiatal hernia repair with: re-do fundoplication in 55%, takedown of fundoplication alone in 24%, Roux-en-Y gastrojejunostomy in 14%, and GE junction resection in 7%. Laparoscopic approach was successful in 81%. RESULTS: Mean duration of operations was 217 min and median length of stay was 3 days. The complication rate was 13%, with 7% undergoing unplanned early re-operation. Patients were followed for mean 11 months, and recurrent hiatal hernia was detected in 13%. Late re-operation was performed in 6% for recurrent hiatal hernia. Recurrent reflux symptomatology resolved in 93%. Dysphagia resolved in 84%. There were no significant differences in outcomes with regard to number of prior operations, operative approach, BMI, or age. CONCLUSIONS: There is no single best approach to remediation in the multi-fundoplication failure patient. Re-do fundoplication is appropriate in over half of patients. Reoperation for multi-fundoplication failure can be performed via minimally invasive approach with excellent remediation of symptoms, low morbidity, and low recurrence rates.

AIM: To evaluate outcomes of surgical remediation for symptomatic or anatomic failure after a transoral incisionless fundoplication (TIF). METHODS: This retrospective study was performed on 11 patients who underwent a remedial operation following TIF failure between June 2011 and September 2016 at the Mayo Clinic in Florida for persistent foregut symptoms. Upper gastrointestinal workup characterized 1 patient as having normal post-TIF anatomy and 10 as having anatomic failure. Ambulatory pH testing was performed in 7 patients and was abnormal in all. All patients underwent a laparoscopic takedown of the prior endoscopic fundoplication and removal of all accessible polypropylene T-fasteners. RESULTS: All patients had esophageal salvage and have not required a reoperation. Anatomical findings included hiatal hernia (7), esophageal diverticulum (2), hiatal mesh erosion of esophagus (1), long-segment esophageal stricture (1), and normal anatomy (1). Remedial operations included laparoscopic explant of fasteners in all patients with conversion to fundoplication (7), resection/imbrication of esophageal diverticulum (2), Heller myotomy (1), and mesh explant and complex esophageal repair (1). Mean operative time was 177 minutes and median length of stay 3 days (range 2-13 days). At mean follow-up of 10.7 months (range 1-42 months), 7 patients had persistent complaints. Esophagogastroduodenoscopy was repeated in these 7 patients and was normal (n = 3), mild stenosis requiring dilation (n = 2), Los Angeles grade B esophagitis (n = 1), and Barrett's esophagus (n = 1). CONCLUSION: Anatomic distortion of the distal esophagus after TIF can be significant, making subsequent operations complex. After remedial surgery, few patients will continue to have troublesome symptoms such as dysphagia.

BACKGROUND: Sporadic nonampullary duodenal neoplasms (SNADN) can have malignant potential for which endoscopic and surgical resections are offered. We report combined gastroenterologic and surgical experience for treatment of SNADN, including endoscopic mucosal resection (EMR) and pancreas-preserving partial duodenectomy (PPPD). METHODS: We retrospectively reviewed 121 consecutive patients, who underwent 30 PPPDs and 91 EMRs for mucosal and submucosal SNADN. Decision to undergo EMR or surgical resection was based on expert endoscopist and surgeon discretion including multidisciplinary tumor board review. Main outcomes were recurrence rate of neoplasia and adverse events requiring hospital admission or prolonged care. EMRs were performed with submucosal lifting followed by snare resection. PPPD included total duodenectomy, supra-ampullary PPPD for neoplasms proximal to the ampulla, and infra-ampullary PPPD for lesions distal to the ampulla. Follow-up data were available for 65% of EMR and 73% of surgical patients. RESULTS: Surgically resected neoplasia was larger with more advanced neoplasia and submucosal lesions. En bloc resection was achieved in all surgical resections and in 53% of EMRs. Post-EMR, mucosal and submucosal neoplasia recurred in 32 and 0%, respectively, including five neoplasms (26%) after an initial negative esophagogastroduodenoscopy. All recurrences were treated endoscopically. Complications occurred in 14 endoscopically and eight surgically treated patients, none requiring surgical intervention. CONCLUSIONS: Post-EMR patients had higher recurrence of mucosal neoplasia, whereas submucosal neoplasms, mainly carcinoid, did not recur. Polyp size and positive resection margin were not associated with neoplasia recurrence. Patients with SNADN could benefit from a multidisciplinary approach to stratify the optimal treatment based on local expertise.

RESUMO
Although there has been debate regarding the optimal procedure to palliate dysphagia in patients with achalasia, emerging reports of longer term follow-up of patients after peroral endoscopic myotomy (POEM) suggest that the POEM procedure is efficacious in relief of dysphagia, and that there is infrequent need for subsequent procedures for treatment of failure or reflux. The number of centers in the United States of America performing POEM for esophageal achalasia continues to increase. This report assess the current knowledge of technical issues of POEM, outcomes after POEM and the status of POEM centers in the U.S.A., and presents the argument for surgeons to participate in the practice of POEM.

BACKGROUND: Repair of giant paraesophageal hernia (PEH) is associated with a favorably high rate of symptom improvement; however, rates of recurrence by objective measures remain high. Herein we analyze our experience with laparoscopic giant PEH repair to determine what factors if any can predict anatomic recurrence. METHODS: We prospectively collected data on PEH characteristics, variations in operative techniques, and surgeon factors for 595 patients undergoing laparoscopic PEH repair from 2008 to 2015. Upper GI study was performed at 6 months postoperatively and selectively thereafter-any supra-diaphragmatic stomach was considered hiatal hernia recurrence. Exclusion criteria included revisional operation (22.4%), size <5 cm (17.6%), inadequate follow-up (17.8%), and confounding concurrent operations (6.9%). Inclusion criteria were met by 202 patients (31% male, median age 71 years, and median BMI 28.7). RESULTS: At a median follow-up of 6 months (IQR 6-12), overall anatomic recurrence rate was 34.2%. Symptom recurrence rate was 9.9% and revisional operation was required in ten patients (4.9%). Neither patient demographics nor PEH characteristics (size, presence of Cameron erosions, esophagitis, or Barrett's) correlated with anatomic recurrence. Technical factors at operation (mobilized intra-abdominal length of esophagus, Collis gastroplasty, number of anterior/posterior stitches, use of crural buttress, use of pledgeted or mattress sutures, or gastrostomy) were also not correlated with recurrence. Regarding surgeon factors, annual volume of fewer than ten cases per year was associated with increased risk of anatomic failure (54 vs 33%, P = 0.02). Multivariate analysis identified surgeon experience (<10 cases per year) as an independent factor associated with early hiatal hernia recurrence (OR 3.7, 95% CI 1.34-10.9). CONCLUSIONS: Laparoscopic repair of giant PEH is associated with high anatomic recurrence rate but excellent symptom control. PEH characteristics and technical operative variables do not appear to significantly affect rates of recurrence. In contrast, surgeon volume does appear to contribute significantly to durability of repair.

BACKGROUND: Helping patients determine which type of bariatric surgery, Roux-en-Y gastric bypass (RYGB) or vertical sleeve gastrectomy (VSG), may be the best treatment can be challenging. This study investigated psychological correlates and their influence on weight loss for patients who underwent RYGB or VSG. METHODS: Four hundred twenty-two patients (RYGB = 305; VSG = 117) completed screening questionnaires presurgery and underwent surgery between August 2012 and April 2015. Associations between demographics and questionnaires with percentage weight change were evaluated using multivariable linear regression models. RESULTS: Median age was 48 years and median BMI 45.3 kg/m2 presurgery. Median percentage changes in weight from baseline to years 1 and 2 follow-up were - 31.5% (range - 52.2 to - 9.2%) and - 31.2% (range - 50.0 to - 1.2%) for RYGB and 25.3% (range - 49.8 to - 4.7%) and - 23.3% (range - 58.9 to - 1.6%) for VSG, respectively. Linear regression models revealed that younger patients lost more weight than older patients at years 1 (RYGB p < 0.0001; VSG p = 0.0001) and 2 (RYGB p = 0.005; VSG p = 0.002). No psychological correlates were significantly associated with weight loss outcomes. Post hoc analyses comparing patients who had surgery to those in the same cohort who did not have surgery revealed significantly higher rates of depression (p < 0.001), anxiety (p < 0.001), binge eating (p = 0.003), night eating (p < 0.001), food addiction (p = 0.042), and lower self-efficacy (p < 0.001) among patients who did not have surgery. DISCUSSION: Patients who are psychologically higher functioning are more likely to complete the evaluation process and undergo bariatric surgery. For patients who had surgery, psychological correlates were not associated with weight loss outcome for either RYGB or VSG. Implications for surgical choice are discussed.

BACKGROUND: Treatment failure with recurrent dysphagia after Heller myotomy occurs in fewer than 10 % of patients, most of whom will seek repeat surgical intervention. These reoperations are technically challenging, and as such, there exist only limited reports of reoperation with esophageal preservation. METHODS: We retrospectively reviewed the records of patients who sought operative intervention from March 1998 to December 2014 for obstructed swallowing after esophagogastric myotomy. All patients underwent a systematic approach, including complete hiatal dissection, takedown of prior fundoplication, and endoscopic assessment of myotomy. Patterns of failure were categorized as: fundoplication failure, inadequate myotomy, fibrosis, and mucosal stricture. RESULTS: A total of 58 patients underwent 65 elective reoperations. Four patients underwent esophagectomy as their initial reoperation, while three patients ultimately required esophagectomy. The remainder underwent reoperations with the goal of esophageal preservation. Of these 58, 46 were first-time reoperations; ten were second time; and two were third-time reoperations. Forty-one had prior operations via a trans-abdominal approach, 11 via thoracic approach, and 6 via combined approaches. All reoperations at our institution were performed laparoscopically (with two conversions to open). Inadequate myotomy was identified in 53 % of patients, fundoplication failure in 26 %, extensive fibrosis in 19 %, and mucosal stricture in 2 %. Intraoperative esophagogastric perforation occurred in 19 % of patients and was repaired. Our postoperative leak rate was 5 %. Esophageal preservation was possible in 55 of the 58 operations in which it was attempted. At median follow-up of 34 months, recurrent dysphagia after reoperation was seen in 63 % of those with a significant fibrosis versus 28 % with inadequate myotomy, 25 % with failed wrap, and 100 % with mucosal stricture (p = 0.10). CONCLUSIONS: Laparoscopic reoperation with esophageal preservation is successful in the majority of patients with recurrent dysphagia after Heller myotomy. The pattern of failure has implications for relief of dysphagia with reoperative intervention.

The diagnosis of esophageal motility disorders has been greatly enhanced with the development of high-resolution esophageal manometry studies and the Chicago Classification. Both hypomotility disorders and hypercontractility disorders of the esophagus have new diagnostic criteria. For the foregut surgeon, new diagnostic criteria for esophageal motility disorders have implications for decision-making during fundoplication and may expand the role of surgical therapy for esophageal achalasia by clarifying diagnostic criteria.

Weight gain or loss is determined by the difference between calorie intake and energy expenditure. The Mifflin metabolic equation most accurately predicts resting energy expenditure (REE) in morbidly obese patients. Hypometabolizers have a measured REE that is much less than predicted and pose the greatest challenge for weight loss induced by restriction of calorie intake. We studied 628 morbidly obese patients (467 female and 161 men, aged 52.5 ± 15.7 years, body mass index [BMI] of 42.6 ± 7.6 m/kg(2) [mean ± SD]). REE was measured using the MedGem® device (REEm) and the percentage variance (ΔREE%) from the Mifflin-predicted expenditure (REEp) was calculated. Patients with ΔREE% more than 1 standard deviation from the mean were defined as hypometabolizers (REEm greater than 27% below REEp) and hypermetabolizers (REEm less than 13% above REEp), respectively. Hypometabolizers had greater REEp (1900 ± 301 vs 1719 ± 346 calories, P = 0.005) and lower REEm (1244 ± 278 vs 2161 ± 438 calories, P < 0.0001) than hypermetabolizers. Hypometabolizers, when compared with hypermetabolizers, were taller (167.2 ± 8.4 vs 164.0 ± 10.9 cm, P = 0.04), heavier (123.6 ± 22.2 vs 110.2 ± 23.1 kg, P = 0.006), and had increased BMI (44.1 ± 6.5 vs 40.8 ± 6.5 kg/m(2), P = 0.04). Other measured anthropometrics were not different between hypo- and hypermetabolizers. Hypometabolizers were less likely to be diabetic (23 vs 43%, P = 0.03) and more likely to be black (25 vs 5%, P = 0.002) than hypermetabolizers. This study defines hypometabolizers as having variance in REEm more than 27 per cent below that predicted by the Mifflin equation. We could not identify any distinguishing phenotypic characteristics of hypometabolizers, suggesting an influence unrelated to body composition.

AIMS: To prospectively examine the effect of modern bariatric surgery on 24-hour urine parameters in a comprehensive care bariatric practice (CCBP). MATERIALS AND METHODS: 47 consecutive patients in our CCBP underwent serum and 24-hour urine analysis pre-operatively, and 30 returned at 12 months for repeat testing. Paired comparisons for serum metabolite and 24-hour urine measures were performed using a Wilcoxon signed-rank test for continuous variables and McNemar's test for categorical variables. Statistical tests were two-sided, with threshold of significance set at p = 0.05. RESULTS: All 30 patients with pre-operative and 12-month follow-up analysis were free of stone events. 20 (67%) had Roux-en-Y gastric bypass (RYGB), 6 (20%) had laparoscopic gastric banding (LGB), and 4 (13%)h ad laparoscopic sleeve gastrectomy (LSG). 24-hour urinary parameters were available for 27 patients. Median urine oxalate (mmol) was 0.29 pre-operatively and 0.21 at 12 months (p = 0.048). Median urine calcium (mg) was 143 pre-operatively and 180 at 12 months (p = 0.11). Median citrate excretion was 527 pre-operatively and 782 at 12 months (p = 0.22). Median serum creatinine was 0.7 pre-operatively and 0.8 at 12 months (p < 0.001). These trends were preserved with the exclusion of LGB and LSG patients. CONCLUSIONS: Modern bariatric surgery (RYGB, LGB, and LSG) as part of a CCBP can still demonstrate alterations of select urinary parameters (particularly oxalate and citrate) in select patients associated with an increased risk of urolithiasis at 1 year follow-up.

OBJECTIVE: To evaluate the use of 2 inexpensive laparoscopic trainers (iTrainers) constructed of easily attainable materials and portable tablets (iPads). METHODS: Two different laparoscopic trainers were constructed using a cardboard box, thumbtacks, and Velcro tape (box trainer). A separate box was constructed using the same supplies with a 3-ring binder (binder trainer). An iPad was used as the camera and monitor for both trainers. A total of 10 participants, including 4 junior surgical residents, 4 senior surgical residents, and 2 surgical staff, completed 3 Fundamentals of Laparoscopic Surgery (FLS) tasks using the 2 "iTrainers." Participants then completed the same tasks on a traditional FLS box trainer. All 10 participants were asked to complete a 13-question survey after the exercises. RESULTS: All the participants (100%) had access to an "iPad" for the visualization component. The 10 participants completed all 3 tasks on all 3 trainers. Senior residents outperformed junior residents on 6 of the 9 total tasks. Attending surgeons outperformed all residents on all tasks and trainers. Survey results revealed the cardboard box "iTrainer" to be the most practical and easiest to construct. CONCLUSION: "iTrainers" are an inexpensive and easy-to-construct alternative to traditional box trainers that might have construct validity as demonstrated in this trial. The box trainer might be easier to construct and have more similarities to the FLS trainer than the binder iTrainer.
