Impedance planimetry during per-oral endoscopic myotomy is associated with decreased inadvertent capnoperitoneum.

BACKGROUND: Per-oral endoscopic myotomy (POEM) has become an accepted minimally invasive alternative to Heller myotomy for the treatment of achalasia and other disorders of esophageal dysmotility. One associated adverse event is the inadvertent creation of capnoperitoneum. A proposed mechanism is that extension of the submucosal tunnel below the esophageal hiatus and onto the gastric wall leads to transmural perforation. We hypothesized that the use of impedance planimetry with the endoscopic functional luminal imaging probe (EndoFLIP) more accurately identifies the esophagogastric junction and helps to better define the myotomy's ideal limits, thus lowering the incidence of inadvertent capnoperitoneum. METHODS: This is a single-center, retrospective review of consecutive POEM cases from 06/11/2011 to 08/08/2022, with EndoFLIP introduced in 2017. Patient and procedural characteristics, including the incidence of clinically significant capnoperitoneum and decompression, were analyzed using univariate and multivariable linear regression statistics. RESULTS: There were 140 POEM cases identified, 74 (52.9%) of which used EndoFLIP. Clinically significant capnoperitoneum was encountered in 26 (18.6%) cases, with no differences in patient characteristics between those who had capnoperitoneum and those who did not. There was a decreased incidence of capnoperitoneum in cases using EndoFLIP compared to those without (n = 6, 23% vs n = 20, 77%, p = 0.001), with zero instances in the final 56 cases. After adjusting for potentially confounding factors, EndoFLIP use was associated with a - 15.93% (95% confidence interval - 30.68%, - 1.18%) decrease in procedure duration. CONCLUSIONS: The routine use of EndoFLIP during POEM was associated with decreased incidence of clinically significant capnoperitoneum, potentially due to improved myotomy tailoring and decreased duration of insufflation with shorter procedure times.

Expert laparoscopist performance on virtual reality simulation tasks with and without haptic features.

BACKGROUND: Virtual reality (VR) simulation for laparoscopic training is available with and without haptic feedback features. Currently, there is limited data on haptic feedback's effect on skill development. Our objective is to compare expert laparoscopists' skills characteristics using VR delivered laparoscopic tasks via haptic and nonhaptic laparoscopic surgical interfaces. METHODS: Five expert laparoscopists performed seven skills tasks on two laparoscopic simulators, one with and one without haptic features. Tasks consisted of 2-handed instrument navigation, retraction and exposure, cutting, electrosurgery, and complicated object positioning. Laparoscopists alternated platforms at default difficulty settings. Metrics included time, economy of movement, completed task elements, and errors. Progressive change in performance for the final three iterations were determined by repeated measures ANOVA. Iteration quartile means were determined and compared using paired t-tests. RESULTS: No change in performance was noted in the last three iterations for any metric. There were no significant differences between platforms on the final two quartiles for most metrics except avoidance of over-stretch error for retraction; and cutting task was significantly better with haptics on all iteration quartiles (p < 0.03). Economy of movement was significantly better with haptics for both hands for clip application (p < 0.01) and better for right hand on complex object positioning (p < 0.05). Accuracy was better with haptics for retraction and cutting (p < 0.05) and clip application (p < 0.05). CONCLUSION: Results showed higher performance in accuracy, efficient instrument motion, and avoidance of excessive traction force on selected tasks performed on VR simulator with haptic feedback compared to those performed without haptics feedback. Laparoscopic surgeons interpreted machine-generated haptic cues appropriately and resulted in better performance with VR task requirements. However, our results do not demonstrate an advantage in skills acquisition, which requires additional study.

What role does the submucosa play in the pathophysiology and treatment of achalasia? An analysis of impedance planimetry during POEM.

BACKGROUND: It is thought the therapeutic benefit of per-oral endoscopic myotomy (POEM) in the treatment of esophageal dysmotility disorders is from longitudinal myotomy creation, but it is unknown if the submucosa contributes to the pathophysiology. This study investigates if submucosal tunnel (SMT) dissection alone contributes to POEM's luminal changes as measured by EndoFLIP. METHODS: A single-center, retrospective review of consecutive POEM cases from June 1, 2011 to September 1, 2022 with intraoperative luminal diameter and distensibility index (DI) data as measured by EndoFLIP. Patients with diagnoses of achalasia or esophagogastric junction outflow obstruction were grouped by those with pre-SMT and post-myotomy measurements (Group 1) and those with a third measurement post-SMT dissection (Group 2). Outcomes and EndoFLIP data were analyzed using descriptive and univariate statistics. RESULTS: There were 66 patients identified, of whom 57 (86.4%) had achalasia, 32 (48.5%) were female, and median pre-POEM Eckardt score was 7 [IQR: 6-9]. There were 42 (64%) patients in Group 1, and 24 (36%) patients in Group 2, with no differences in baseline characteristics. In Group 2, SMT dissection changed luminal diameter by 2.15 [IQR: 1.75-3.28]cm, which comprised 38% of the median 5.6 [IQR: 4.25-6.3]cm diameter of complete POEM change. Similarly, the median post-SMT change in DI of 1 [IQR: 0.5-1.2]units comprised 30% of the median 3.35 [2.4-3.98]units overall change in DI. Post-SMT diameters and DI were both significantly lower than the full POEM. CONCLUSIONS: Esophageal diameter and DI are significantly affected by SMT dissection alone, though not equaling the magnitude of diameter or DI changes from full POEM. This suggests that the submucosa does play a role in achalasia, presenting a future target for refining POEM and developing alternative treatment strategies.

Factors influencing surgeon well-being: qualitatively exploring the joy of surgery.

BACKGROUND: There has been considerable research into burnout but much less into how surgeons thrive and find joy. This study, conducted by the SAGES Reimagining the Practice of Surgery Task Force, explored factors influencing surgeon well-being, the eventual goal being translating findings into tangible changes to help restore the joy in surgery. METHODS: This was a qualitative, descriptive study. Purposive sampling ensured representation across ages, genders, ethnicities, practice types, and geographies. Semi-structured interviews were recorded and transcribed. We coded inductively, finalized the codebook by consensus, and then constructed a thematic network. Global themes formed our conclusions; organizing themes gave additional detail. Analysis was facilitated by NVivo. RESULTS: We interviewed 17 surgeons from the US and Canada. Total interview time was 15 hours. Our global and organizing themes were: Stressors (Work-life Integration, Administration-related Concerns, Time and Productivity Pressures, Operating Room Factors, and Lack of Respect). Satisfaction (Service, Challenge, Autonomy, Leadership, and Respect and Recognition). Support (Team, Personal Life, Leaders, and Institutions). Values (Professional and Personal). Suggestions (Individual, Practice, and System level). Values, stressors, and satisfaction influenced perspectives on support. Experiences of support shaped suggestions. All participants reported stressors and satisfiers. Surgeons at all stages enjoyed operating and being of service. Supports and suggestions included compensation and infrastructure, but human resources were most critical. To experience joy, surgeons needed high-functioning clinical teams, good leaders/mentors, and supportive family/social networks. CONCLUSIONS: Our results indicated organizations could (1) better understand surgeons' values, like autonomy; (2) provide more time for satisfiers, like patient relationship building; (3) minimize stressors, like time and financial pressures; and (4) at all levels focus on (4a) building teams and leaders and (4b) giving surgeons time and space for healthy family/social lives. Next steps include developing an assessment tool for individual institutions to build "joy improvement plans" and to inform surgical associations' advocacy efforts.

Gastroparesis: an evidence-based review for the bariatric and foregut surgeon.

Gastroparesis is a gastric motility disorder characterized by delayed gastric emptying. It is a rare disease and difficult to treat effectively; management is a dilemma for gastroenterologists and surgeons alike. We conducted a systematic review of the literature to evaluate current diagnostic tools as well as treatment options. We describe key elements in the pathophysiology of the disease, in addition to current evidence on treatment alternatives, including nutritional considerations, medical and surgical options, and related outcomes.

Per-oral endoscopic myotomy for the treatment of non-achalasia esophageal dysmotility disorders: experience from a single high-volume center.

BACKGROUND: Achalasia is a rare disorder of esophageal motility that induces progressive intolerance to oral intake. Other esophageal dysmotility disorders include esophagogastric junction outflow obstruction (EGJOO), distal esophageal spasm (DES), hypercontractile esophagus (HE), and other minor disorders of peristalsis (MDP) and can present similarly to achalasia despite different pathophysiologies. Prior studies have demonstrated the safety and efficacy of POEM in the treatment of achalasia, but little is reported regarding POEM's role in treating non-achalasia esophageal dysmotility disorders (NAEDD). This study aims to assess the safety and efficacy of POEM in the treatment of NAEDD. STUDY DESIGN: This is a retrospective review of consecutive POEM cases from June 1, 2011, to February 1, 2021. NAEDD were characterized according to the Chicago classification. Primary outcome measure was the resolution of preoperative symptoms. Secondary outcomes include preoperative diagnosis, myotomy length, conversion to laparoscopic or open procedure, operative time, and length of stay (LOS). Technical success was defined as the completion of an 8 cm myotomy including the esophagogastric junction (EGJ) and extending 2 cm distal to the EGJ. Clinical success was defined as a postoperative Eckardt score ≤ 3. RESULTS: Of 124 cases of POEM performed during the study period, 17 were performed for NAEDD. Technical success was achieved in all 17 patients (100%). Of the fifteen patients that had documented postoperative Eckardt scores, 13 were ≤ 3, achieving a clinical success rate of 87%. Subgroup analysis (HE/MDP/DES vs. EGJOO) showed no significant differences in the preoperative or postoperative Eckardt scores between groups, and both groups demonstrated a significant decrease in Eckardt scores after POEM. No cases were aborted for technical or clinical reasons, and there were no adverse outcomes. CONCLUSION: POEM is a safe and efficacious treatment modality for NAEDD. Further work is needed to develop optimal treatment strategies for this complex group of diseases.

Long-Term, Prospective, Multicenter Study of Poly-4-Hydroxybutyrate Mesh (Phasix Mesh) for Hernia Repair in Cohort at Risk for Complication: 60-Month Follow-Up.

BACKGROUND: Long-term resorbable mesh represents a promising technology for ventral and incisional hernia repair (VIHR). This study evaluates poly-4-hydroxybutyrate mesh (P4HB; Phasix Mesh) among comorbid patients with CDC class I wounds. STUDY DESIGN: This prospective, multi-institutional study evaluated P4HB VIHR in comorbid patients with CDC class I wounds. Primary outcomes included hernia recurrence and surgical site infection. Secondary outcomes included pain, device-related adverse events, quality of life, reoperation, procedure time, and length of stay. Evaluations were scheduled at 1, 3, 6, 12, 18, 24, 30, 36, and 60 months. A time-to-event analysis (Kaplan-Meier) was performed for primary outcomes; secondary outcomes were reported as descriptive statistics. RESULTS: A total of 121 patients (46 male, 75 female) 54.7 ± 12.0 years old with a BMI of 32.2 ± 4.5 kg/m 2 underwent VIHR with P4HB Mesh (mean ± SD). Fifty-four patients (44.6%) completed the 60-month follow-up. Primary outcomes (Kaplan-Meier estimates at 60 months) included recurrence (22.0 ± 4.5%; 95% CI 11.7% to 29.4%) and surgical site infection (10.1 ± 2.8%; 95% CI 3.3 to 14.0). Secondary outcomes included seroma requiring intervention (n = 9), procedure time (167.9 ± 82.5 minutes), length of stay (5.3 ± 5.3 days), reoperation (18 of 121, 14.9%), visual analogue scale-pain (change from baseline -3.16 ± 3.35 cm at 60 months; n = 52), and Carolinas Comfort Total Score (change from baseline -24.3 ± 21.4 at 60 months; n = 52). CONCLUSIONS: Five-year outcomes after VIHR with P4HB mesh were associated with infrequent complications and durable hernia repair outcomes. This study provides a framework for anticipated long-term hernia repair outcomes when using P4HB mesh.

Use of minimally invasive surgery for the management of hollow viscus traumatic injuries.

BACKGROUND: The objective of this study is to assess surgical outcomes following the initial use of laparoscopy versus laparotomy when managing patients with hollow viscus injuries due to trauma. METHODS: Using the database from the American College of Surgeons Trauma Quality Improvement Program we identified all patients from 2015-2017 with ICD-10 Diagnosis codes for hollow viscus trauma. Types of procedures were identified by ICD-10 PCS codes. Patient outcomes were stratified by major trauma(ISS > 15) and minor trauma. Continuous variables were compared by ANOVA and categorical variables compared by Chi-Square. Analysis performed using STATA 16. RESULTS: We identified 16,284 patients that matched inclusion criteria within the study time frame. Of those, 1986 patients received a surgical intervention, 1911(96%) were open and 75(4%) were laparoscopic. In blunt trauma there were 106 diagnostic procedures, 87(82%) were open and 19(18%) were laparoscopic. There were 574 therapeutic procedures, 543(95%) were open and 31(5%) were laparoscopic. In penetrating trauma there were 223 diagnostic procedures, 215(96%) were open and 8(4%) were laparoscopic. There were 1039 therapeutic procedures for penetrating trauma, 1023(98%) were open and 16(2%) were laparoscopic. For minor trauma, mean length of stay(days) after open surgery was 5 while for laparoscopy it was 2 (p = 0.04). There were 203 complications noted in the open group and 7 in the laparoscopic group (p = 0.19). For major trauma, mean length of stay(days) after open surgery was 5 and 6 for laparoscopy p = 0.54). There were 242 complications in the open group and 1 in the laparoscopic group (p = 0.07). There was no noted significant difference noted in the disposition at discharge in either group in both major and minor trauma. CONCLUSIONS: For those that required surgery for hollow viscous injury, laparoscopy appeared to be safe, had less adverse outcomes and was underutilized, particularly when only a diagnostic procedure was required.

Metabolic and bariatric surgery is likely safe, but underutilized in adolescents aged 13-17 years.

BACKGROUND: Bariatric surgery is now accepted for adolescents; however, we may need to improve access to surgery for this vulnerable age group. OBJECTIVES: To compare the demographic characteristics and short-term safety outcomes of adolescents, college-aged individuals, and young adults who have had metabolic and bariatric surgery. SETTING: Bariatric surgery centers. METHODS: Patients aged 13-25 years in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database from 2015-2018 with a Current Procedural Terminology (CPT) code for sleeve gastrectomy (SG) or gastric bypass (GB) were included. Patients were stratified by operation and analyzed by age: adolescents (13-17 yr), college-aged (18-21 yr), and young adults (22-25 yr). RESULTS: Of the 760,076 patients in the database, 1047 adolescents (.1%), 10,429 college-aged individuals (1.4%), and 24,841 young adults (3.8%) underwent SG or GB. The majority of patients in each group were female and white. Diabetes was most common among adolescents, hypertension among college-aged individuals. The most prevalent co-morbidity among young adults was diabetes. Preoperative BMI was 47 across all age strata. SG was performed in 27,292 patients: 879 (3.2%) adolescents, 7955 (29.2%) college-aged, and 18,447 (67.6%) young adults. Postoperative complications occurred in approximately 1% of individuals and were similar between age groups (P = .23). A total of 8292 patients underwent GB: 146 (1.8%) adolescents, 2207 (26.6%) college-aged, and 5939 (71.6%) young adults. There was no difference in 30-day complication rates between age groups (P = .32). CONCLUSIONS: There may be a disparity in access to metabolic and bariatric surgery among adolescents, particularly for racial and ethnic minorities; however, these procedures are likely safe in adolescents as young as 13.

Impedance planimetry values for predicting clinical response following peroral endoscopic myotomy.

BACKGROUND: There is growing interest in developing impedance planimetry as a tool to enhance the clinical outcomes for endoscopic and surgical management of achalasia. The primary aim of this study was to determine whether impedance planimetry measurements can predict clinical response and reflux following peroral endoscopic myotomy (POEM). METHODS: A multicenter cohort study of patients with achalasia undergoing POEM was established from prospective databases and retrospective chart reviews. Patients who underwent impedance planimetry before and after POEM were included. Clinical response was defined as an Eckardt score of ≤ 3. Tenfold cross-validated area under curve (AUC) values were established for the different impedance planimetry measurements associated with clinical response and reflux development. RESULTS: Of the 290 patients included, 91.7 % (266/290) had a clinical response and 39.4 % (108/274) developed reflux following POEM. The most predictive impedance planimetry measurements for a clinical response were: percent change in cross-sectional area (%ΔCSA) and percent change in distensibility index (%ΔDI), with AUCs of 0.75 and 0.73, respectively. Optimal cutoff values for %ΔCSA and %ΔDI to determine a clinical response were a change of 360 % and 272 %, respectively. Impedance planimetry values were much poorer at predicting post-POEM reflux, with AUCs ranging from 0.40 to 0.62. CONCLUSION: Percent change in CSA and distensibility index were the most predictive measures of a clinical response, with a moderate predictive ability. Impedance planimetry values for predicting reflux following POEM showed weak predictive capacity.

Prospective, multicenter study of P4HB (Phasix™) mesh for hernia repair in cohort at risk for complications: 3-Year follow-up.

BACKGROUND: This study represents a prospective, multicenter, open-label study to assess the safety, performance, and outcomes of poly-4-hydroxybutyrate (P4HB, Phasix™) mesh for primary ventral, primary incisional, or multiply-recurrent hernia in subjects at risk for complications. This study reports 3-year clinical outcomes. MATERIALS AND METHODS: P4HB mesh was implanted in 121 patients via retrorectus or onlay technique. Physical exam and/or quality of life surveys were completed at 1, 3, 6,12, 18, 24, and 36 months, with 5-year (60-month) follow-up ongoing. RESULTS: A total of n = 121 patients were implanted with P4HB mesh (n = 75 (62%) female) with a mean age of 54.7 ± 12.0 years and mean BMI of 32.2 ± 4.5 kg/m2 (±standard deviation). Comorbidities included: obesity (78.5%), active smokers (23.1%), COPD (28.1%), diabetes mellitus (33.1%), immunosuppression (8.3%), coronary artery disease (21.5%), chronic corticosteroid use (5.0%), hypo-albuminemia (2.5%), advanced age (5.0%), and renal insufficiency (0.8%). Hernias were repaired via retrorectus (n = 45, 37.2% with myofascial release (MR) or n = 43, 35.5% without MR), onlay (n = 8, 6.6% with MR or n = 24, 19.8% without MR), or not reported (n = 1, 0.8%). 82 patients (67.8%) completed 36-month follow-up. 17 patients (17.9% ± 0.4%) experienced hernia recurrence at 3 years, with n = 9 in the retrorectus group and n = 8 in the onlay group. SSI (n = 11) occurred in 9.3% ± 0.03% of patients. CONCLUSIONS: Long-term outcomes following ventral hernia repair with P4HB mesh demonstrate low recurrence rates at 3-year (36-month) postoperative time frame with no patients developing late mesh complications or requiring mesh removal. 5-year (60-month) follow-up is ongoing.

The COVID-19 reset: lessons from the pandemic on Burnout and the Practice of Surgery.

BACKGROUND: Burnout among physicians is an increasing concern, and surgeons are not immune to this threat. The ongoing COVID-19 pandemic has caused dramatic changes to surgeon workflow, often leading to redeployment to other clinical areas, slowdown and shutdown of elective surgery practices, and an uncertain future of surgical practice in the post-pandemic setting. Paradoxically, for many surgeons who had to prepare for but not immediately care for a major surge, the crisis did allow for reflective opportunities and a resetting of priorities that could serve to mitigate chronic patterns contributory to Burnout. METHODS: SAGES Reimagining the Practice of Surgery task force convened a webinar to discuss lessons learned from the COVID pandemic that may address burnout. RESULTS: Burnout is multifactorial and may vary in cause among different generation/experience groups. Those that report burnout symptoms often complain of lacking purpose or meaning in their work. Although many mechanisms to address Burnout are from a defensive standpoint-including coping mechanisms, problem solving, and identification of a physician having wellness difficulties-offensive mechanisms such as pursuing purpose and meaning and finding joy in one's work can serve as reset points that promote thriving and fulfillment. Understanding what motivates physicians will help physician leaders to develop and sustain effective teams. Reinvigorating the surgical workforce around themes of meaning and joy in the service rendered via our surgical skills may diminish Burnout through generative and aspirational strategies, as opposed to merely reactive ones. Fostering an educational environment free of discriminatory or demeaning behavior may produce a new workforce conducive to enhanced and resilient wellbeing at the start of careers. CONCLUSION: Surgeon wellness and self-care must be considered an important factor in the future of all healthcare delivery systems, a need reaffirmed by the COVID-19 pandemic.

S054: incidence and management of jejunojejunal intussusception after Roux-en-Y gastric bypass: a large case series.

INTRODUCTION: Jejunojejunal intussusception after Roux-en-Y gastric bypass (RYGBP) for morbid obesity is a rare but potentially catastrophic complication. There are limited data regarding the incidence of intussusception and the different surgical options for management of this disease. METHODS: This is a retrospective review of all patients that underwent RYGBP and subsequently developed intussusception at the jejunojejunostomy. Data were collected between 1/1/2008 and 5/31/2018 and included demographics, details related to the index procedure, presentation, and management of intussusception. Perioperative outcomes and complications were also collected. RESULTS: 665 patients underwent RYGBP. A total of 34 patients developed intussusception, with 31 (4.7%) of them having undergone RYGBP in our hospital. Demographics included age, gender, and BMI at both the index surgery and at the time of intussusception. The jejunojejunostomy was created during RYGBP using a linear stapler in all patients with 64.5% of them achieving a length of 90 mm. All intussuscepted patients presented acutely with abdominal pain. All but one patient required surgical intervention. 42.4% of the patients were found to have intraoperative intussusception which appeared to be retrograde in 78.6% of them. Reduction followed by enteropexy or just enteropexy was performed in 20 patients (60.6%) that required surgery. No immediate post-operative complications were noted but 8 patients (26.5%) had recurrence of intussusception requiring another surgical intervention. In the reoperated group, 75% of the patients were treated with reduction followed by enteropexy or just enteropexy. CONCLUSIONS: This is the largest case series describing jejunojejunal intussusception following RYGBP. All patients that developed intussusception had jejunojejunostomy length greater than 60 mm. The most commonly performed surgical repair was reduction of the intussuscepted segment (if present) followed by enteropexy. Jejunojejunostomy length greater than 60 mm might be associated with the occurrence of intussusception and could explain the higher incidence noted in our series. Minimal intervention with enteropexy can offer effective treatment for most patients.

Systematic review of management of gallbladder disease in patients undergoing minimally invasive bariatric surgery.

The introduction and subsequent widespread adaptation of minimally invasive approaches for bariatric surgery have not only changed the outcomes of bariatric surgery but also called into question the management of co-morbid surgical conditions, in particular gallbladder disease. The American Society for Metabolic and Bariatric Surgery Foregut Committee performed a systematic review of the published literature from 1995-2018 on management of gallbladder disease in patients undergoing bariatric surgery. The papers reviewed generated the following results. (1) Routine prophylactic cholecystectomy at the time of bariatric surgery is not recommended. (2) In symptomatic patients who are undergoing bariatric surgery, concomitant cholecystectomy is acceptable and safe. (3) Ursodeoxycholic acid may be considered for gallstone formation prophylaxis during the period of rapid weight loss. (4) Routine preoperative screening and postoperative surveillance ultrasound is not recommended in asymptomatic patients. In the era of minimally invasive surgery, the management of gallbladder disease in patients undergoing bariatric surgery continues to evolve.

Public reporting and transparency: a primer on public outcomes reporting.

INTRODUCTION: Healthcare consumers seeking accurate information about where to find quality surgical care face a confusing constellation of rating systems that lack transparency or consistency of opinion. For example, a 2016 report in Health Affairs demonstrated that no hospital was rated as a high performer by all four prominent national ratings systems: Consumer Reports, Leapfrog, Healthgrades and U.S. News & World Report (Austin et al. Health Aff 34:423-430, 2015). Surgeons should have an understanding of the current state of public reporting of quality; hospital ratings and data sources; physician ratings and data sources; and transparency of reporting. METHODS: We conducted a non-systematic review of the literature. RESULTS: Hospital quality ratings remain nebulous and there is not universal opinion on the utility of voluntary participation in ranking systems, leaving the current systems largely opinion-based. Early attempts at physician ranking systems are rudimentary at best and suffer from methodological concerns. Publicly reported metrics should be easily understandable, accessible, clinically relevant, reliable, non-punitive, and shielded from legal discovery. Transparency is increasing within institutions to help align staff to institutional objectives, while specialty specific registries are helping to standardize care pathways and outcomes measures across organizations. Measuring surgical outcomes beyond 30-day morbidity and mortality has been plagued by a lack of understanding on how to create metrics that matter; the four attributes of relevance, scientific soundness, feasibility and comprehensiveness set a high bar for the development of effective and efficient quality measures in surgery. DISCUSSION: SAGES, via the Quality, Outcomes, and Safety Committee, is committed to learning how to develop meaningful quality metrics in general surgery and will continue to work in other areas that impact quality, such as opioid prescribing, and surgeon wellness.

Developing minimally invasive procedure quality metrics: one step at a time.

BACKGROUND: Despite extensive first-hand surgical experience, rank and file members of surgical societies are generally not trained in and have not therefore been included in surgical quality measure development. The purpose of this exercise was to determine if a structured quality metric design tool could bridge this gap, facilitating rapid development of focused quality metrics by minimally invasive surgeon attendees of the April 2018 SAGES Annual Meeting. METHODS: Expert minimally invasive surgeons attended a 90-min workshop with didactic and interactive quality metric design sessions during the Annual Meeting. The interactive portion was formed around a novel structured quality measure development tool that graded presenting symptoms, short-term complications, and long-term disutility of care. RESULTS: For first-time symptomatic inguinal hernia repair, first-time small to moderate size ventral hernia repair, and elective laparoscopic cholecystectomy, each workgroup was able to develop one quality, one short-term complication, and one long-term disutility metric. CONCLUSIONS: A structured quality metric design tool facilitates application of knowledge through rapid development of multifaceted, patient-centric outcomes measures by expert minimally invasive surgeons, otherwise not formally trained in metric development. The exercise also highlighted the need to rigorously define denominator populations and to guard against metric-driven undertreatment.

Myotomy length informed by high-resolution esophageal manometry (HREM) results in improved per-oral endoscopic myotomy (POEM) outcomes for type III achalasia.

INTRODUCTION: High-resolution esophageal manometry (HREM) is essential in characterizing achalasia subtype and the extent of affected segment to plan the myotomy starting point during per-oral endoscopic myotomy (POEM). However, evidence is lacking that efficacy is improved by tailoring myotomy to the length of the spastic segment on HREM. We sought to investigate whether utilizing HREM to dictate myotomy length in POEM impacts postoperative outcomes. METHODS: Comparative analysis of HREM-tailored to non-tailored patients from a prospectively collected database of all POEMs at our institution January 2011 through July 2017. A tailored myotomy is defined as extending at least the length of the diseased segment, as initially measured on HREM. RESULTS: Forty patients were included (11 tailored versus 29 non-tailored). There were no differences in patient age (p = 0.6491) or BMI (p = 0.0677). Myotomy lengths were significantly longer for tailored compared to non-tailored overall (16.6 ± 2.2 versus 13.5 ± 1.8; p < 0.0001), and for only type III achalasia (15.9 ± 2.4 versus 12.7 ± 1.2; p = 0.0453), likely due to more proximal starting position in tailored cases (26.0 ± 2.2 versus 30.0 ± 2.7; p < 0.0001). Procedure success (Eckardt < 3) was equivalent across groups overall (p = 0.5558), as was postoperative Eckardt score (0.2 ± 0.4 versus 0.8 ± 2.3; p = 0.4004). Postoperative Eckardt score was significantly improved in the tailored group versus non-tailored for type III only (0.2 ± 0.4 versus 1.3 ± 1.5; p = 0.0435). A linear correlation was seen between increased length and greater improvement in Eckardt score in the non-tailored group (p = 0.0170). CONCLUSIONS: Using HREM to inform surgeons of the proximal location of the diseased segment resulted in longer myotomies, spanning the entire affected segment in type III achalasia, and in lower postoperative Eckardt scores. Longer myotomy length is often more easily achieved with POEM than with Heller myotomy, which raises the question of whether POEM results in better outcomes for type III achalasia, as types I and II do not generally have measurable spastic segments.

Treatment of Achalasia with Per-Oral Endoscopic Myotomy: Analysis of 50 Consecutive Patients.

BACKGROUND: Peroral endoscopic myotomy (POEM) has become an acceptable incisionless treatment for achalasia based on encouraging outcomes in multiple series worldwide. This report reflects our early experience. METHODS: Data were collected prospectively on all patients undergoing POEM between June 2011 and April 2016 under IRB approval. Diagnosis of achalasia was confirmed by standard preoperative work-up. Primary outcome was symptom relief, measured by Eckardt score. Secondary outcomes were operative time, length of stay (LOS), adverse events, failure, and recurrence. RESULTS: Fifty patients were included; 30 were female. Mean age was 55.7 ± 17.7 years. Mean BMI was 29.5 ± 9.2. Median OR time was 133.5 minutes (range 70-462); average myotomy was 13.1 ± 2.3 cm. One early case was converted to a laparoscopic Heller myotomy due to extensive submucosal fibrosis from a recent Botox injection. Two cases were aborted; one due to extensive submucosal fibrosis and the other to intraoperative capnopericardium. Median LOS was 1 day (range 0.8-8). Two major complications occurred: intraoperative cardiac arrest due to capnopericardium and postoperative submucosal hemorrhage. There were no deaths. Mean postoperative Eckardt score was 1.0 ± 1.9 (range 0-8) at 2-6 weeks (vs. preoperative score 7.7 ± 2.8; P < .0001); mean dysphagia component 0.35 ± 0.28 (vs. preoperative score 2.6 ± 0.7; P < .0001). Two recurrences were identified, both at 6 months. CONCLUSIONS: POEM is a safe and durable treatment for achalasia in the short term. We demonstrated marked improvement of symptoms in all completed cases. There was an acceptable serious adverse event rate of 4%, failure of 6% due to patient selection, and recurrences occurring in only 4% of cases.

An international multicenter study evaluating the clinical efficacy and safety of per-oral endoscopic myotomy in octogenarians.

BACKGROUND AND AIMS: Per-oral endoscopic myotomy (POEM) for achalasia is particularly appealing in the elderly because it is minimally invasive. However, data in patients aged ≥80 years are scarce. The aim of this study was to assess the clinical outcome of POEM in octogenarians. METHODS: This was a multicenter retrospective study at 8 centers. Consecutive octogenarians with achalasia who underwent POEM between 2010 and 2016 were included. Rates of technical success (completion of myotomy), clinical response (Eckardt score ≤3), and adverse events (severity graded as per American Society for Gastrointestinal Endoscopy lexicon) were assessed. RESULTS: A total of 76 patients (47.4% female, mean age 84 years) underwent POEM for treatment of achalasia: type I, 17.1%; type II, 35.5%; type III, 17.1%; and unspecified, 30.3%. Overall, 41.1% were treatment naïve, whereas others had previous botulinum toxin injection and/or pneumatic dilation. The mean (± standard deviation [SD]) age-adjusted Charlson comorbidity index score was 6.2 ± 2.4, with the majority of patients having American Society of Anesthesiologists Physical Status Classification System (ASA) scores of II/III. Technical success was 93.4%, with a median follow-up of 256 days. Fourteen adverse events occurred in 11 patients (14.5%). There were 3 inadvertent mucosotomies, 6 cases of symptomatic capnoperitoneum and/or capnomediastinum, 2 esophageal leaks, 1 cardiac arrhythmia, and 2 other). The severities of these adverse events were mild (78.6%), moderate (14.3%), and severe (7.1%). Clinical success was achieved in 90.8% of patients, with a mean (± SD) Eckardt score reduction from 7.0 ± 2.3 to 0.8 ± 0.1 (P < .001), a median follow-up of 256 days, and interquartile range of 66 to 547. CONCLUSION: Although the rate of technical success may be somewhat lower and the rate of adverse events slightly higher than previously reported, our data suggest that POEM in octogenarians is safe and effective, supporting its role as a primary modality for achalasia in this patient population.
