Patients Engaged in Losing Weight Preoperatively Experience Improved Outcomes After Hiatal Hernia Repair.

BACKGROUND: Adherence to preoperative weight loss recommendations may serve as a surrogate for the level of engagement in hiatal hernia (HH) patients. This study aims to evaluate the relationship between achieving preoperative weight loss goals and outcomes after HH repair. METHODS: A retrospective review of 235 patients undergoing laparoscopic HH repair at a single institution was performed. Patients were grouped based on the percentage of weight loss goal achieved. Low achievement was defined as the bottom quartile of goal achievement (≤75%); high achievement was defined as the top quartile (≥140%). Baseline characteristics, clinical outcomes, and patient reported outcomes (PROMs) were compared between groups. RESULTS: 131/235 (55.7%) achieved their weight loss goal. No differences in baseline characteristics or clinical outcomes were observed between the low and high achievement groups. While both groups experienced improvements in PROMs postoperatively, patients in the high achievement group demonstrated significantly lower symptom burden at one-month postoperatively. Further, high-achievement patients were more likely to experience complete resolution of common HH symptoms at one-month postoperatively, including no difficulty swallowing food, no breathing difficulties or choking episodes, no choking when eating food, no choking when drinking liquid, and no regurgitation of food or liquid. CONCLUSIONS: In patients undergoing laparoscopic HH repair, patients achieving their preoperative weight loss goals experienced less overall symptom burden and lower prevalence of common symptoms one-month postoperatively than those with low levels of goal achievement. These results demonstrate that patients can take an active role in improving their own surgical outcomes and health status.

Comparison of Kinect and Leap Motion for Intraoperative Image Interaction.

Background. Touchless interaction devices have increasingly garnered attention for intraoperative imaging interaction, but there are limited recommendations on which touchless interaction mechanisms should be implemented in the operating room. The objective of this study was to evaluate the efficiency, accuracy, and satisfaction of 2 current touchless interaction mechanisms-hand motion and body motion for intraoperative image interaction. Methods. We used the TedCas plugin for ClearCanvas DICOM viewer to display and manipulate CT images. Ten surgeons performed 5 image interaction tasks-step-through, pan, zoom, circle measure, and line measure-on the 3 input interaction devices-the Microsoft Kinect, the Leap Motion, and a mouse. Results. The Kinect shared similar accuracy with the Leap Motion for most of the tasks. But it had an increased error rate in the step-through task. The Leap Motion led to shorter task completion time than the Kinect and was preferred by the surgeons, especially for the measure tasks. Discussion. Our study suggests that hand tracking devices, such as the Leap Motion, should be used for intraoperative imagining manipulation tasks that require high precision.

Morgagni Hernia Repair: A Review.

Anteromedial subcostosternal defects, also known as a diaphragmatic hernia of Morgagni (MH), allow potentially life-threatening herniation of the abdominal organs into the thorax. Constituting only a small fraction of all types of congenital diaphragmatic hernias, correct diagnosis of MH is often delayed, owing in large part to nonspecific associated respiratory and gastrointestinal complaints. Once identified, the primary management for both symptomatic and incidentally discovered asymptomatic cases of MH are surgical correction because the herniated contents present increasing risk for strangulation. Various thoracic and abdominal surgical approaches have been described without a clear consensus on preference for operative repair technique. In this article, the literature regarding management of MH within the past decade is reviewed, and an illustrative case of laparoscopic repair of a MH with novel reinforcement using a Falciform ligament onlay flap is presented.

Intraoperative "Micro Breaks" With Targeted Stretching Enhance Surgeon Physical Function and Mental Focus: A Multicenter Cohort Study.

OBJECTIVE: The aim of this study was to investigate the effect of intraoperative targeted stretching micro breaks (TSMBs) on the experienced pain and fatigue, physical functions, and mental focus of surgeons. BACKGROUND: Surgeons are routinely subject to mental and physical stresses through the course of their work in the operating room. One of the factors most contributory to the shortening of a surgeon's career is work-related pain and its effects on patient safety and personal relationships. METHODS: Surgeons and operating room staff from 4 medical centers rated pain/fatigue, physical, and mental performance using validated scales during 2 operative days: 1 day without implementing TSMB, the other including standardized (1.5 to 2 minutes) guided TSMB at appropriate 20 to 40-minute intervals throughout each case. Case type and duration were recorded as were surgeon pain data before and after each procedure and at the end of the surgical day. Individual body part pre/postdiscomfort difference was modeled, controlling for clinical center. Random coefficient mixed models accounted for surgeon variability. RESULTS: Sixty-six participants (69% men, 31% women; mean 47 years) completed 193 "non-TSMB" and 148 "TSMB" procedures. Forty-seven percent of surgeons were concerned that musculoskeletal pain may shorten their career. TSMB improved surgeon postprocedure pain scores in the neck, lower back, shoulders, upper back, wrists/hands, knees, and ankles. Operative duration did not differ (P> 0.05). Improved pain scores with TSMB were statistically equivalent (P > 0.05) for laparoscopic and open procedures. Surgeons perceived improvements in physical performance (57%) and mental focus (38%); 87% of respondents planned to continue TSMB. CONCLUSIONS: Many surgeons are concerned about career-ending or limiting musculoskeletal pain. Intraoperative TSMB may represent a practical, effective means to reduce surgeon pain, enhance performance, and increase mental focus without extending operative time.

Primary versus redo paraesophageal hiatal hernia repair: a comparative analysis of operative and quality of life outcomes.

INTRODUCTION: We compared patient outcomes after initial versus redo paraesophageal hernia (PEH) repair at two high-volume GI surgery centers. MATERIALS AND METHODS: Retrospective review analyzed one-year outcomes after initial versus redo elective laparoscopic PEH repair, including wound/non-wound-related complications and quality of life benefits as measured by four validated instruments: reflux symptom index, gastroesophageal reflux disease health-related, laryngopharyngeal reflux, and swallowing scales. RESULTS: Three hundred and seventeen patients (271 initial and 46 redo) underwent laparoscopic PEH repair. Groups differed with respect to age (64.6 vs. 60.2 years, p = 0.027), but were comparable in gender (71.2 vs. 67.4% female, p = 0.596), BMI (29.0 vs. 27.6 kg/m2, p = 0.100), and ASA score (2.3 vs. 2.3 p = 0.666). Redo surgery was more complex with longer mean operative times (112.2 vs. 139.1 min, p < 0.001). Groups did not statistically differ with respect to 30-day wound (0.7 vs. 2.2%, p = 0.363) and non-wound (6.0 vs. 8.7%, p = 0.511)-related complications. After one year of follow-up, QOL analysis revealed that initial versus redo groups significantly benefited from operative intervention. CONCLUSIONS: Although redo PEH repairs are more complex, patients enjoy equivalent operative outcomes and quality of life benefits compared to initial surgery lending support to the significance of surgeon experience and high-volume centers in optimizing outcomes.

"See one, do one, teach one": inadequacies of current methods to train surgeons in hernia repair.

INTRODUCTION: Residency/fellowship training in hernia repair is still too widely characterized by the "see one, do one, teach one" model. The goal of this study was to perform a needs assessment focused on surgical training to guide the creation of a curriculum by SAGES intended to improve the care of hernia patients. METHODS: Using mixed methods (interviews and online survey), the SAGES hernia task force (HTF) conducted a study asking subjects about their perceived deficits in resident training to care for hernia patients, preferred training topics about hernias, ideal learning modalities, and education development. RESULTS: Participants included 18 of 24 HTF members, 27 chief residents and fellows, and 31 surgical residents. HTF members agreed that residency exposes trainees to a wide spectrum of hernia repairs by a variety of surgeons. They cited outdated materials, techniques, and paucity of feedback. Additionally, they identified the "see one, do one, teach one" method of training as prevalent and clearly inadequate. The topics least addressed were system-based approach to hernia care (46 %) and patient outcomes (62 %). Training topics residents considered well covered during residency were: preoperative and intraoperative decision-making (90 %), complications (94 %), and technical approach for repairs (98 %). Instructional methods used in residency include assisted/supervised surgery (96 %), Web-based learning (24 %), and simulation (30 %). Residents' preferred learning methods included simulation (82 %), Web-based training (61 %), hands-on laboratory (54 %), and videos (47 %), in addition to supervised surgery. Trainees reported their most desired training topics as basic techniques for inguinal and ventral hernia repairs (41 %) versus advanced technical training (68 %), which mirrored those reported by attending surgeons, 36 % and 71 %, respectively. CONCLUSIONS: There was a consensus among HTF members and surgical trainees that a comprehensive, dynamic, and flexible educational program employing various media to address contemporary key deficits in the care of hernia patients would be welcomed by surgeons.

Raising the quality of hernia care: Is there a need?

INTRODUCTION: With a focus on raising the quality of hernia care through creation of educational programs, SAGES formed the Hernia Task Force (HTF). This study used needs assessment survey to target opportunities for improving surgical training and thus patient outcomes and experience. METHODS: This qualitative study included structured interviews and online surveys of key stakeholders: HTF members, surgeons, nurses, patients, hospital administrators, healthcare payers and medical suppliers. Questions included perceptions of recurrence and complication rates, their etiologies, perceived deficits in current hernia care and the most effective and training modalities. RESULTS: A total of 841 participants included 665 surgeons, 66 patient care team members, 12 hospital administrators and 14 medical supply providers. Assessment of technical approach revealed that nearly 26 % of surgeons apply the same, limited range of techniques to all patients without evaluation of patient-specific factors. The majority (71 %) of surgeon respondents related hernia recurrence rates nearing 25 % or more. HTF members implicated surgeon factors (deficits in knowledge/technique, etc.) as primary determinants of recurrences, whereas nurses, medical supply providers and hospital administrators implicated patient health factors. Surgeons preferred attending conferences (82 %), reading periodicals/publications (71 %), watching videos (59 %) and communicating with peers (57 %) for learning and skill improvement. Topics of the greatest interest were advanced techniques for hernia repairs (71 %), preoperative and intraoperative decision making (56 %) and patient outcomes (64 %). Eighty-six percent of nurses felt that there was room for improvement in hernia patient safety and teamwork in the OR. Only 24 % believed that the patients had adequate preoperative education. CONCLUSIONS: Major reported deficits in hernia care include: lack of standardization in training and care, "one size fits all" technical approach and inadequate patient follow-up/outcome measures. There is a need for a comprehensive, flexible and tailored educational program to equip surgeons and their teams to raise the quality of hernia care and bring greater value to their patients.

Comparative assessment of physical and cognitive ergonomics associated with robotic and traditional laparoscopic surgeries.

BACKGROUND: We conducted this study to investigate how physical and cognitive ergonomic workloads would differ between robotic and laparoscopic surgeries and whether any ergonomic differences would be related to surgeons' robotic surgery skill level. Our hypothesis is that the unique features in robotic surgery will demonstrate skill-related results both in substantially less physical and cognitive workload and uncompromised task performance. METHODS: Thirteen MIS surgeons were recruited for this institutional review board-approved study and divided into three groups based on their robotic surgery experiences: laparoscopy experts with no robotic experience, novices with no or little robotic experience, and robotic experts. Each participant performed six surgical training tasks using traditional laparoscopy and robotic surgery. Physical workload was assessed by using surface electromyography from eight muscles (biceps, triceps, deltoid, trapezius, flexor carpi ulnaris, extensor digitorum, thenar compartment, and erector spinae). Mental workload assessment was conducted using the NASA-TLX. RESULTS: The cumulative muscular workload (CMW) from the biceps and the flexor carpi ulnaris with robotic surgery was significantly lower than with laparoscopy (p < 0.05). Interestingly, the CMW from the trapezius was significantly higher with robotic surgery than with laparoscopy (p < 0.05), but this difference was only observed in laparoscopic experts (LEs) and robotic surgery novices. NASA-TLX analysis showed that both robotic surgery novices and experts expressed lower global workloads with robotic surgery than with laparoscopy, whereas LEs showed higher global workload with robotic surgery (p > 0.05). Robotic surgery experts and novices had significantly higher performance scores with robotic surgery than with laparoscopy (p < 0.05). CONCLUSIONS: This study demonstrated that the physical and cognitive ergonomics with robotic surgery were significantly less challenging. Additionally, several ergonomic components were skill-related. Robotic experts could benefit the most from the ergonomic advantages in robotic surgery. These results emphasize the need for well-structured training and well-defined ergonomics guidelines to maximize the benefits utilizing the robotic surgery.

GOALS-incisional hernia: a valid assessment of simulated laparoscopic incisional hernia repair.

The Global Operative Assessment of Laparoscopic Skills (GOALS) is a valid and reliable measure of basic, non-procedure-specific laparoscopic skills. GOALS-incisional hernia (GOALS-IH) was developed to evaluate performance of laparoscopic incisional hernia repair (LIHR). The purpose of this study was to assess the validity and reliability of GOALS-IH during LIHR simulation. GOALS-IH assesses 7 domains with a maximum score of 35. A total of 12 experienced surgeons and 10 novices performed LIHR on the Surgical Abdominal Wall simulator. Performance was assessed by a trained observer and by self-assessment using GOALS-IH, basic GOALS and a visual analog scale (VAS) for overall competence. Both interrater reliability and internal consistency were high (.76 and .95 respectively). Experienced surgeons had higher mean GOALS-IH scores than novices (32.3 ± 2 versus 22.7 ± 5). There was excellent correlation between GOALS-IH and other measures of performance (GOALS r = .93 and VAS r = .93). GOALS-IH is easy to use, valid and reliable for assessment of simulated LIHR.

A research portfolio for innovation in the surgical environment.

The University of Maryland Medical Center and School of Medicine have sponsored a program of research targeted at the enabling of technologies for enhanced training, clinical effectiveness and patient safety. The pillars of this research included scientific approaches related to Informatics, Smart Image, Simulation and Ergonomics and Human Factors. The evolving research effort opened the door to a revised concept of basic surgical sciences that underpin training and performance in the operative environment.

Laparoscopic repair of ventral incisional hernias: pros and cons.

Abdominal wall hernias are a familiar surgical problem. Millions of patients are affected each year, presenting most commonly with primary ventral, incisional, and inguinal hernias. Whether symptomatic or asymptomatic, hernias commonly cause pain or are aesthetically distressing to patients. These concerns, coupled with the risk of incarceration, are the most common reasons patients seek surgical repair of hernias. This article focuses on incisional hernias, reported to develop in 3% to 29% of laparotomy incisions.

Development of a more robust tool for postural stability analysis of laparoscopic surgeons.

BACKGROUND: Physical difficulties experienced by surgeons performing minimally invasive surgery (MIS) are being given extensive attention by ergonomic researchers. Postural stability, not commonly addressed, is our prime focus. Center of pressure (COP) alone is used in the few existing postural stability studies. Using COP, we previously correlated postural stability to instrument type, task difficulty, and skill level. This study, including center of mass (COM), sway area analysis, and what we uniquely term postural stability demand (PSD), extends our investigation. METHODS: Six surgeons from different experience levels were recruited to complete three fundamentals of laparoscopy (FLS(TM)) tasks. Standing on two force plates, participants performed each task as a motion capture system recorded body movements. An ellipse was created for sway area analysis of COP, the point where the ground reaction force was located, and COM, the point at which body mass was concentrated. PSD was defined as the mean distance between the COP and COM locations in the anterior-posterior (A-P) or medial-lateral (M-L) directions. Postural parameters and performance time were correlated. RESULTS: COM and COP sway areas positively correlated with pegboard transfer performance time (r = 0.928, p < 0.05; r = 0.864, p < 0.05) and also with circle-cutting performance time (r = 0.858, p < 0.05; r = 0.779, p = 0.06). However, COM and COP sway areas negatively correlated with endo-loop placement performance time (r = -0.925, p < 0.05; r = -0.935, p < 0.05). These results indicate unique postural controls based on skill level. During all tasks, PSD in the A-P direction strongly correlated with performance time (r = 0.829, p < 0.05; r = 0.913, p < 0.05; r = 0.880, p < 0.05), indicating that less-skilled participants experienced increased postural demands. CONCLUSIONS: This study demonstrated that variance in postural adjustments, as evidenced by sway area analysis, correlate to skill level and individual task. Strong correlation between PSD and performance time shows potential as a predictor of skill levels. Combining COM, COP, and PSD data produces a more robust analytic tool for identifying postural adjustments that can be correlated with skill level.

Integration of virtual reality and conventional skills trainers: a mixed resource model.

Training surgical skills in virtual reality (VR) trainers holds promise for successful skill acquisition. VR can simulate complex procedures, present varied physiology, and provide detailed performance feedback. However, VR trainers have not gained wide acceptance as a dominant training modality. Simple mechanical "box trainers" are still used more widely for training basic skills, with the possibility of training more complex skills using more sophisticated physical models of physiology. Combining both VR and mechanical box trainers in a unified curriculum can capitalize on the strengths of VR and the strengths of simple mechanical trainers in an integrated program of practice and feedback. Diagnostics from performance on VR trainers can be used to develop a personalized curriculum for practice on box trainers, with detailed feedback provided through intermittent VR sessions. This integrated approach can increase resource utilization, improve training efficiency, and may lead to better transfer of training to the patient-care environment.

Postural instability does not necessarily correlate to poor performance: case in point.

BACKGROUND: It is very important for surgeons who perform minimally invasive surgery (MIS) to maintain proper postural stability, which kinematic research can determine. Previous studies in surgical ergonomics have shown that postural stability is correlated to instrument type, task difficulty, and skill level. What should also be considered is that surgeons may strategically change stance or joint movement to achieve better surgical outcomes while potentially subjecting themselves to greater risk. Background information about subjects, e.g., joint impairment, should be considered an important surgical ergonomic element. Such information can lead to more realistic and accurate conclusions about postural stability and joint kinematics. METHODS: A highly experienced and skilled right-handed surgeon developing carpal tunnel syndrome in both wrists was recruited into a small (6 subjects) performance study of pegboard transfer and circle-cutting tasks from the Fundamentals of Laparoscopic Surgery (FLS) skill set. Joint kinematics and postural data were collected using two associated force plates and a motion capture system of 12 digital, high-resolution, high-speed, infrared cameras. RESULTS: Each task was completed in less than 90 s. In pegboard transfer, the subject increased shoulder abduction angle to align his hand and forearm and minimize wrist flexion. When circle-cutting required excessive wrist flexion, the subject maintained his lower body position and stance while twisting his torso, a strategy that appeared to stabilize tangential direction related to cutting while maintaining a fixed orientation of forearm, wrist, and hand. In another circle-cutting trial, the subject changed his stance primarily by shifting foot position as necessary to obtain better scissor approach angles. These compensatory, strategic movements caused an increase in overall postural sway but did not represent postural instability. CONCLUSION: This case study indicated that poor joint kinematics or postural stability does not necessarily correlate to poor performance. Instead, they may indicate positive compensatory or strategic movements.

Do shorter lengths of stay increase readmissions after total joint replacements?

BACKGROUND: Enhanced recovery after surgery protocols for total joint replacements (TJRs) emphasize early discharge, yet the impact on readmissions is not well documented. We evaluate the impact of a one-day length of stay (LOS) discharge protocol on readmissions. METHODS: We conducted a retrospective review of all primary TJRs (hip and knee) from April 2014 to March 2015. Patients who had adequate support to be discharged home were categorized into 2 groups, 1-day (n = 174) vs 2-day (n = 285) LOS groups. Patients discharged to rehabilitation were excluded (n = 196). RESULTS: Patients in the 1 day group were more likely to be younger (61.7 vs 64.8 years, P < .001), be male (56.3% vs 40.4%, P = .001), and have a lower body mass index (30.0 vs 31.4 kg/m2, P = .012). One-day LOS patients had shorter surgical times (79.7 vs 85.6 minutes, P = .001) and more likely had spinal anesthesia (46.0% vs 31.2%, P = .001). The overall 30-day all-cause (2.3% vs 2.5%, P = .591) and 90-day wound-related (1.1% vs 1.1%, P = .617) readmission rates were equivalent between groups. CONCLUSIONS: Early discharge does not increase readmissions and may help attenuate costs associated with TJRs. Further refinement of protocols may allow for more patients to be safely discharged on postoperative day 1.

Patients are well served by Collis gastroplasty when indicated.

BACKGROUND: Debate persists over the impact of Collis gastroplasty (CG) on outcomes after anti reflux surgery. This study analyzed operative and quality of life (QOL) outcomes from one of the largest series of laparoscopic anti reflux surgery (LARS) with CG reported to date. METHODS: A retrospective review was conducted to compare outcomes between patients undergoing LARS with CG versus without CG at two large centers with expertise in foregut surgery from October 2004-December 2011 and July 2012-September 2016. Demographic, perioperative, and QOL data were reviewed. Four validated surveys were used for QOL outcomes: reflux symptom index (RSI), gastroesophageal reflux disease health-related QOL (GERD-HRQL), laryngopharyngeal reflux health-related QOL (LPR-HRQL), and swallowing QOL (SWAL-QL). RESULTS: 480 patients consisted of 149 Collis vs 331 non-Collis with mean age of 66.3 vs 58.9 years (P ≤ .001), BMI of 28.6 vs 29.7 (P = .040) and ASA score of 2.4 vs 2.2 (P = .005) were included. Collis patients underwent longer duration operations (133.2 mins vs 94.2; P ≤ .001) with greater duration of hospital stay (3.1 vs 1.8; P ≤ .001). Thirty-day readmission and reoperation rates were equivalent between the two groups. Wound and non-wound related complications were also comparable. After mean 12 month follow up, QOL assessment revealed significant improvements for all patients post-surgery with comparable results between Collis and non-Collis patients. Furthermore, CG did not contribute to post-operative dysphagia, reflux, or a significant leak rate. CONCLUSION: Patients who require a CG to address a true short esophagus during LARS have comparable operative and QOL benefits as non-Collis patients without added morbidity or mortality.

Potential Operating Room Fire Hazard of Bone Cement.

Approximately 600 cases of operating room (OR) fires are reported annually. Despite extensive fire safety education and training, complete elimination of OR fires still has not been achieved. Each fire requires an ignition source, a fuel source, and an oxidizer. In this case report, we describe the potential fire hazard of bone cement in the OR. A total knee arthroplasty was performed with a standard medial parapatellar arthrotomy. Tourniquet control was used. After bone cement was applied to the prepared tibial surface, the surgeon used an electrocautery device to resect residual lateral meniscus tissue-and started a fire in the operative field. The surgeon suffocated the fire with a dry towel and prevented injury to the patient. We performed a PubMed search with a cross-reference search for relevant papers and found no case reports outlining bone cement as a potential fire hazard in the OR. To our knowledge, this is the first case report identifying bone cement as a fire hazard. OR fires related to bone cement can be eliminated by correctly assessing the setting time of the cement and avoiding application sites during electrocautery.

Management of gastroesophageal reflux disease: medications, surgery, or endoscopic therapy? (Current status and trends).

Gastroesophageal reflux disease (GERD) is a common chronic disorder in the Western world. The basic cause of GERD has been well characterized--the fundamental defect is a loss of integrity of the gastroesophageal barrier. What is less clear is the most appropriate means of addressing this reflux. GERD has a variety of symptoms, ranging from typical presentations of heartburn and regurgitation (without esophagitis) to atypical presentations, such as severe erosive esophagitis and its associated complications. Because of its symptomatic diversity, physicians may select from a variety of therapeutic approaches. Medical therapy aims at decreasing acidity by suppressing proton secretion and has been well established. Available medications include antacids and alginates, H2-receptor antagonists, motility agents, and proton pump inhibitors (PPIs). Antireflux surgery, commonly performed laparoscopically, aims at reinforcing and repairing the defective barrier through plication of the gastric fundus. The earliest performed successful procedures were the Nissen and Toupet fundoplications, to which several modifications have since been made. It has been demonstrated in preliminary studies and long-term outcomes of such open surgery and preliminary studies of such laparoscopic surgery that antireflux surgery is an effective approach, with overall outcomes superior to those achieved with medications. The precise indications for the surgical treatment of patients with GERD, however, remain controversial. In recent years, endoscopic intraluminal antireflux approaches have attracted the attention of physicians, surgeons, and commercial companies, especially after the approval of two endoscopic intraluminal methods by the United States FDA in 2000. The common element is prevention of acid reflux by construction of a functional or controlled barrier in the lower esophageal sphincter zone. Three main methods are currently employed: endoscopic intraluminal valvuloplasty, endoscopic radiofrequency therapy, and endoscopic injection or implantation of foreign material. The endoluminal suturing method is highly demanding technically, and its short-term results are encouraging, although largely dependent on the experience of the endoscopist. Several prospective cohort studies have shown that the radiofrequency procedure (Stretta) significantly improves GERD symptoms and quality of life while reducing esophageal acid exposure and eliminating the need for antisecretory medications in the majority of patients within 6-12 months. Most recently, some researchers have studied the endoluminal implantation of polymers, such as Plexiglas (polymethyl-methylacrylate), Gatekeeper hydrogel, and Enteryx (ethylene vinyl alcohol copolymer). The preliminary results of these studies showed that the implantation method was feasible and safe; however, the only multicenter trial related to outcome that has been published has included just 1 year of follow-up. Here, we review the treatment of GERD: medical, surgical, and endoscopic. In addition, we provide an algorithm based on symptoms and response to treatment for management of these patients.
