RESUMO
BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) is an effective, minimally invasive gastric remodeling procedure to treat mild and moderate obesity. Early adoption of ESG may be desirable to try to halt progression of obesity, but there are few data on its efficacy and safety for overweight patients. METHODS: This was a multicenter, international, analytical case series. Six U.S., 1 Brazilian, 1 Mexican, and 1 Indian center were included. Overweight patients according to local practice undergoing ESG were considered eligible for the study. The end points were percent total weight loss (%TWL), body mass index (BMI) reduction, rate of BMI normalization, and rate of adverse events. RESULTS: One hundred eighty-nine patients with a mean age of 42.6 ± 14.1 years and a mean BMI of 27.79 ± 1.17 kg/m2 were included. All procedures were successfully accomplished, and there were 3 intraprocedural adverse events (1.5%). The mean %TWL was 12.28% ± 3.21%, 15.03% ± 5.30%, 15.27% ± 5.28%, and 14.91% ± 5.62% at 6, 12, 24, and 36 months, respectively. At 12 and 24 months, 76% and 86% of patients achieved normal BMI, with a mean BMI reduction of 4.13 ± 1.46 kg/m2 and 4.25 ± 1.58 kg/m2. There was no difference in mean %TWL in the first quartile versus the fourth quartile of BMI in any of the time points. However, the BMI normalization rate was statistically higher in the first group at 6 and 12 months (6 months, 100% vs 48.5% [P < .01]; 12 months, 86.2% vs 50% [P < .01]; 24 months, 84.6% vs 76.1% [P = .47]; 36 months, 86.3% vs 66.6% [P = .26]). CONCLUSIONS: ESG is safe and effective in treating overweight patients with high BMI normalization rates. It could help halt or delay the progression to obesity.

BACKGROUND AND AIMS: Opioid-induced esophageal dysfunction (OIED) often presents as spastic esophageal disorders (SEDs) and esophagogastric junction outflow obstruction (EGJOO). The aim of this study was to evaluate and compare clinical outcomes of peroral endoscopic myotomy (POEM) for SEDs and EGJOO among opioid users and nonusers. METHODS: This propensity score (PS) matching study included consecutive opioid users and nonusers who underwent POEM for SEDs and EGJOO between January 2018 and September 2022. The following covariates were used for the PS calculation: age, sex, duration of symptoms, Eckardt score, type of motility disorder, and length of myotomy during POEM. Clinical response was defined as a post-POEM Eckardt score ≤3. RESULTS: A total of 277 consecutive patients underwent POEM during the study period. PS matching resulted in the selection of 64 pairs of patients strictly matched 1:1 (n = 128) with no statistically significant differences in demographic, baseline, or procedural characteristics or in the parameters considered for the PS between the 2 groups. Clinical response to POEM was significantly lower among opioid users (51 of 64 [79.7%]) versus nonusers (60 of 64 [93.8%]) (P = .03) at a median follow-up of 18 months. Among opioid users, higher opioid dose (>60 morphine milligram equivalents per day) was associated with a higher likelihood of failure to respond to POEM (odds ratio, 4.59; 95% confidence interval, 1.31-3.98; P = .02). CONCLUSIONS: Clinical response to POEM for SEDs and EGJOO is significantly lower among opioid users versus nonusers. There was a dose-relationship between opioids and response to POEM, with higher daily opioid usage associated with a higher likelihood of treatment failure.

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

BACKGROUND: Endoluminal functional impedance planimetry and panometry assesses secondary peristalsis in response to volumetric distention under sedation. We hypothesize that impedance planimetry and panometry can replace high-resolution manometry in the preoperative assessment prior to anti-reflux surgery. METHODS: Single institution prospective data were collected from patients undergoing anti-reflux surgery between 2021 and 2023. A 16-cm functional luminal imaging probe (FLIP) assessed planimetry and panometry prior to surgery under general anesthesia at the start of each case. Panometry was recorded and esophageal contractile response was classified as normal (NCR), diminished or disordered (DDCR), or absent (ACR) in real time by a single panometry rater, blinded to preoperative HRM results. FLIP results were then compared to preoperative HRM. RESULTS: Data were collected from 120 patients, 70.8% female, with mean age of 63 ± 3 years. There were 105 patients with intraoperative panometry, and 15 with panometry collected during preoperative endoscopy. There were 60 patients (50%) who had peristaltic dysfunction on HRM, of whom 57 had FLIP dysmotility (55 DDCR, 2 ACR) resulting in 95.0% sensitivity. There were 3 patients with normal secondary peristalsis on FLIP with abnormal HRM, all ineffective esophageal motility (IEM). No major motility disorder was missed by FLIP. A negative predictive value of 91.9% was calculated from 34/37 patients with normal FLIP panometry and normal HRM. Patients with normal HRM but abnormal FLIP had larger hernias compared to patients with concordant studies (7.5 ± 2.8 cm vs. 5.4 ± 3.2 cm, p = 0.043) and higher preoperative dysphagia scores (1.5 ± 0.7 vs. 1.1 ± 0.3, p = 0.021). CONCLUSION: Impedance planimetry and panometry can assess motility under general anesthesia or sedation and is highly sensitive to peristaltic dysfunction. Panometry is a novel tool that has potential to streamline and improve patient care and therefore should be considered as an alternative to HRM, especially in patients in which HRM would be inaccessible or poorly tolerated.

INTRODUCTION: Zenker's diverticulum (ZD) is a false pulsion diverticulum of the cervical esophagus. It is typically found in older adults and manifests with dysphagia. The purpose of this study is to describe our experience with Per-oral endoscopic myotomy for Zenker's (Z-POEM) and intraoperative impedance planimetry (FLIP). METHODS: We performed a single institution retrospective review of patients undergoing Z-POEM in a prospective database between 2014 and 2022. Upper esophageal sphincter (UES) distensibility index (DI, mm2/mmHg) was measured by FLIP before and after myotomy. The primary outcome was clinical success. Secondary outcomes included technical failure, adverse events, and quality of life as assessed by the gastroesophageal health-related quality of life (GERD-HRQL), reflux severity index (RSI), and dysphagia score. A statistical analysis of DI was done with the paired t-test (p < 0.05). RESULTS: Fifty-four patients underwent Z-POEM, with FLIP measurements available in 30 cases. We achieved technical success and clinical success in 54/54 (100%) patients and 46/54 patients (85%), respectively. Three patients (6%) experienced contained leaks. Three patients were readmitted: one for aforementioned contained leak, one for dysphagia, and one post-operative pneumonia. Three patients with residual dysphagia underwent additional endoscopic procedures, all of whom had diverticula > 4 cm. Following myotomy, mean DI increased by 2.0 ± 1.7 mm2/mmHg (p < 0.001). In those with good clinical success, change in DI averaged + 1.6 ± 1.1 mm2/mmHg. Significant improvement was found in RSI and GERD-HRQL scores, but not dysphagia score. CONCLUSION: Z-POEM is a safe and feasible for treatment of ZD. We saw zero cases of intraoperative abandonment. We propose that large diverticula (> 4 cm) are a risk factor for poor outcomes and may require additional endoscopic procedures. An improvement in DI is expected after myotomy, however, the ideal range is still not known.

INTRODUCTION: Numerous studies comment on quality of life outcomes comparing complete and partial fundoplication with or without a bougie. Society guidelines are moving toward recommending partial fundoplication over complete fundoplication due to improved side effect profile with similar outcomes. Retrospective studies and randomized trials have elucidated that use of a bougie during Nissen fundoplication does impact long-term dysphagia. To date there are no retrospective or prospective data that guide practice for partial fundoplications. OBJECTIVE: The purpose of this project is to investigate the clinical implications of using a bougie for Toupet fundoplication with regard to short-term and long-term dysphagia and need for further therapeutic interventions. METHODS: A retrospective review of a prospectively maintained gastroesophageal database was performed. Demographic, pre-operative quality of life outcomes data, perioperative, and post-operative quality of life outcomes data of 373 patients from 2011 to 2022 undergoing Toupet fundoplication without bougie or with a traditional Savary 56Fr or 58Fr bougie were reviewed. The two groups were compared using student's t-test to identify statically significant differences between the groups. RESULTS: Between 2011 and 2022, 373 patients underwent Toupet fundoplication (276 with traditional bougie, 97 without). Median follow-up in the bougie group was 19 months, versus 9 months in the non bougie group. There was no difference between early (3 weeks) and late dysphagia scores (6 months). In the bougie group there were two mucosal perforations due to the bougie. There were no statistically significant differences in GERD-HRQL, gas bloat, and dysphagia scores between groups at one year. CONCLUSION: There is no difference observed in early or late dysphagia scores, GERD-HRQL, gas bloat or need for dilation in patients undergoing Toupet fundoplication with or without a traditional bougie. It is reasonable to discontinue the use of a traditional bougie during Toupet fundoplication, especially due to risk of esophageal perforation.
RESUMO
BACKGROUND: Per-oral plication of the (neo)esophagus (POPE) is an endoscopic procedure used to improve emptying of the defunctionalized esophagus or gastric conduit, with the hope of improving symptoms and quality of life. As this procedure has only been performed in the United States for the past 4 years, safety and efficacy have not been well established. METHODS: This is a retrospective case series for patients who underwent POPE from a single institution between 2019 and 2023. Data collected included demographics, preoperative diagnoses and treatments, imaging, endoscopic data, operative intervention, 90-day complications, and response to treatment. Quality of life and patient satisfaction data were collected by phone survey. RESULTS: Seventeen cases were identified, encompassing 13 primary procedures and 4 repeat POPEs (re-POPE). Eight patients had end-stage achalasia and 5 had impaired gastric emptying after esophagectomy with gastric conduits. Median age was 65 years and median ASA was 3, with 38.5% female patients. POPE was performed with 2-6 plication sutures in an average of 75 min. The majority of patients discharged home the same day. For the 17 procedures, there were 4 complications. Two patients required antibiotics for pneumonia, while 4 required procedural intervention. There were no deaths. Preoperative symptoms improved or resolved at initial follow up in 82.3% of patients. Four patients experienced symptom recurrence and required re-POPE, 1 with achalasia and 3 with gastric conduits. Although all achalasia patients had an "end-stage esophagus," none have required esophagectomy since the introduction of POPE. CONCLUSIONS: POPE is an endoscopic procedure that is efficacious in relieving emptying difficulties for the end-stage esophagus and gastric conduit. It may obviate the need for esophagectomy or conduit replacement. Also, it can be repeated in select patients. While the risk profile of complications is favorable compared to alternative operations, patients with gastric conduits are at higher risk.
RESUMO
BACKGROUND: Anti-reflux operations are effective treatments for GERD. Despite standardized surgical techniques, variability in post-operative outcomes persists. Most patients with GERD possess one or more characteristics that augment their disease and may affect post-operative outcomes-a GERD "phenotype". We sought to define these phenotypes and to compare their post-operative outcomes. METHODS: We performed a retrospective review of a prospective gastroesophageal database at our institution, selecting all patients who underwent an anti-reflux procedure for GERD. Patients were grouped into different phenotypes based on the presence of four characteristics known to play a role in GERD: hiatal or paraesophageal hernia (PEH), hypotensive LES, esophageal dysmotility, delayed gastric emptying (DGE), and obesity. Patient-reported outcomes (GERD-HRQL, dysphagia, and reflux symptom index (RSI) scores) were compared across phenotypes using the Wilcoxon rank-sum test. RESULTS: 690 patients underwent an anti-reflux procedure between 2008 and 2022. Most patients underwent a Nissen fundoplication (302, 54%), followed by a Toupet or Dor fundoplication (205, 37%). Twelve distinct phenotypes emerged. Non-obese patients with normal esophageal motility, normotensive LES, no DGE, with a PEH represented the most common phenotype (134, 24%). The phenotype with the best post-operative GERD-HRQL scores at one year was defined by obesity, hypotensive LES, and PEH, while the phenotype with the worst scores was defined by obesity, ineffective motility, and PEH (1.5 ± 2.4 vs 9.8 ± 11.4, p = 0.010). There was no statistically significant difference in GERD-HRQL, dysphagia, or RSI scores between phenotypes after five years. CONCLUSIONS: We have identified distinct phenotypes based on common GERD-associated patient characteristics. With further study these phenotypes may aid surgeons in prognosticating outcomes to individual patients considering an anti-reflux procedure.

BACKGROUND: Laparoscopic cholecystectomy with common bile duct exploration (LCBDE) is equivalent in safety and efficacy to endoscopic retrograde cholangiopancreatography (ERCP) plus laparoscopic cholecystectomy (LC) while decreasing number of procedures and length of stay (LOS). Despite these advantages LCBDE is infrequently utilized. We hypothesized that formal, simulation-based training in LCBDE would result in increased utilization and improve patient outcomes across participating institutions. METHODS: Data was obtained from an on-going multi-center study in which simulator-based transcystic LCBDE training curricula were instituted for attending surgeons and residents. A 2-year retrospective review of LCBDE utilization prior to LCBDE training was compared to utilization up to 2 years after initiation of training. Patient outcomes were analyzed between LCBDE strategy and ERCP strategy groups using χ2, t tests, and Wilcoxon rank tests. RESULTS: A total of 50 attendings and 70 residents trained in LCBDE since November 2020. Initial LCBDE utilization rate ranged from 0.74 to 4.5%, and increased among all institutions after training, ranging from 9.3 to 41.4% of cases. There were 393 choledocholithiasis patients analyzed using LCBDE (N = 129) and ERCP (N = 264) strategies. The LCBDE group had shorter median LOS (3 days vs. 4 days, p < 0.0001). No significant differences in readmission rates between LCBDE and ERCP groups (4.7% vs. 7.2%, p = 0.33), or in post-procedure pancreatitis (0.8% v 0.8%, p > 0.98). In comparison to LCBDE, the ERCP group had higher rates of bile duct injury (0% v 3.8%, p = 0.034) and fluid collections requiring intervention (0.8% v 6.8%, p < 0.009) secondary to cholecystectomy complications. Laparoscopic antegrade balloon sphincteroplasty had the highest technical success rate (87%), followed by choledochoscopic techniques (64%). CONCLUSION: Simulator-based training in LCBDE results in higher utilization rates, shorter LOS, and comparable safety to ERCP plus cholecystectomy. Therefore, implementation of LCBDE training is strongly recommended to optimize healthcare utilization and management of patients with choledocholithiasis.

BACKGROUND: Endoscopic sleeve gastroplasty (ESG) is an endolumenal, organ-sparing therapy for obesity, with wide global adoption. We aimed to explore the efficacy and safety of ESG with lifestyle modifications compared with lifestyle modifications alone. METHODS: We conducted a randomised clinical trial at nine US centres, enrolling individuals aged 21-65 years with class 1 or class 2 obesity and who agreed to comply with lifelong dietary restrictions. Participants were randomly assigned (1:1·5; with stratified permuted blocks) to ESG with lifestyle modifications (ESG group) or lifestyle modifications alone (control group), with potential retightening or crossover to ESG, respectively, at 52 weeks. Lifestyle modifications included a low-calorie diet and physical activity. Participants in the primary ESG group were followed up for 104 weeks. The primary endpoint at 52 weeks was the percentage of excess weight loss (EWL), with excess weight being that over the ideal weight for a BMI of 25 kg/m2. Secondary endpoints included change in metabolic comorbidities between the groups. We used multiple imputed intention-to-treat analyses with mixed-effects models. Our analyses were done on a per-protocol basis and a modified intention-to-treat basis. The safety population was defined as all participants who underwent ESG (both primary and crossover ESG) up to 52 weeks. FINDINGS: Between Dec 20, 2017, and June 14, 2019, 209 participants were randomly assigned to ESG (n=85) or to control (n=124). At 52 weeks, the primary endpoint of mean percentage of EWL was 49·2% (SD 32·0) for the ESG group and 3·2% (18·6) for the control group (p<0·0001). Mean percentage of total bodyweight loss was 13·6% (8·0) for the ESG group and 0·8% (5·0) for the control group (p<0·0001), and 59 (77%) of 77 participants in the ESG group reached 25% or more of EWL at 52 weeks compared with 13 (12%) of 110 in the control group (p<0·0001). At 52 weeks, 41 (80%) of 51 participants in the ESG group had an improvement in one or more metabolic comorbidities, whereas six (12%) worsened, compared with the control group in which 28 (45%) of 62 participants had similar improvement, whereas 31 (50%) worsened. At 104 weeks, 41 (68%) of 60 participants in the ESG group maintained 25% or more of EWL. ESG-related serious adverse events occurred in three (2%) of 131 participants, without mortality or need for intensive care or surgery. INTERPRETATION: ESG is a safe intervention that resulted in significant weight loss, maintained at 104 weeks, with important improvements in metabolic comorbidities. ESG should be considered as a synergistic weight loss intervention for patients with class 1 or class 2 obesity. This trial is registered with ClinicalTrials.gov, NCT03406975.

BACKGROUND: Zenker's diverticulum peroral endoscopic myotomy (zPOEM) is a minimally invasive treatment strategy for Zenker's diverticulum, with excellent results for management of small-to-moderate Zenker's diverticulum. We evaluated its use in the management of large Zenker's diverticulum. METHODS: This was a retrospective multicenter cohort study across 11 international centers including adult patients with large Zenker's diverticulum ≥â40âmm treated by zPOEM between March 2017 and March 2022.âThe primary outcome was clinical success (dysphagia score ≤â1 without need for further intervention). Secondary outcomes included technical success (complete myotomy as intended), adverse events (AEs), and rate of recurrence. RESULTS: 83 patients (male 62.7â%, mean age 72.6 [SD 11.5] years) underwent zPOEM for treatment of large Zenker's diverticulum (median size 50âmm, interquartile range [IQR] 41-55âmm, range 40-80âmm). The zPOEM procedure was technically successful in 82 patients (98.8â%), with a mean procedure time of 48.7 (SD 23.2) minutes. Clinical success was achieved in 71 patients (85.5â%). Median (IQR) symptom scores improved significantly from baseline for dysphagia (2 2 3 vs. 0 [0-2]; Pâ<â0.001), regurgitation (3 2 3 4 vs. 0 [0-0]; Pâ<â0.001), and respiratory symptoms (2 [0-3] vs. 0 [0-0]; Pâ<â0.001). Among patients achieving clinical success, only one recurrence (1.4â%) was recorded during a median follow-up of 12.2 months (IQR 3-28). Post-procedure AEs, all mild to moderate, occurred in four patients (4.8â%). CONCLUSION: This study demonstrated safe and effective use of zPOEM in the management of large Zenker's diverticulum.

BACKGROUND: Surgical treatment options of gastroesophageal reflux disease have changed significantly in the last 50 years. Magnetic Sphincter Augmentation (MSA) and Anti-reflux Mucosectomy (ARMs) are gaining traction but there is a paucity of literature comparing these novel options to Toupet fundoplication and gold standard Nissen fundoplication. METHODS: This is a retrospective review of a prospectively maintained database, evaluating patients undergoing Nissen, Toupet, MSA, and ARMs. Pre-operative, intra-operative, and post-operative variables including Reflux symptom index (RSI), Gastroesophageal Reflux Disease-Health Related Quality of Life questionnaire (GERD-HRQL), and Dysphagia scores were compared between groups. RESULTS: During the study period, 649 patients underwent anti-reflux surgery. Patients who underwent Nissen or Toupet were younger than those undergoing MSA or ARMs (65 ± 12 and 67 ± 14 years vs 56 ± 14 and 56 ± 18 years, P < 0.01). Average operative time for Nissen was 127 ± 40 min which was similar to a Toupet at 122 ± 32 min. These durations were significantly longer than for MSA, averaging 79 ± 29, and ARMs, at a mean 35 ± 3 min (all P < 0.001). Length of stay was significantly different among all four groups with Nissen, Toupet, MSA, and ARMs patients staying a median of 31, 24, 7, and 3 h post operatively, respectively (all P < 0.001). Complications and re-admissions were similarly low among all groups. Despite minor differences in RSI and GERD-HRQL scores at isolated follow-up time points, quality of life scores seems to be similar overall at up to 5 years follow-up. Gas bloat and dysphagia did not differ among groups at any time point. CONCLUSIONS: Novel anti-reflux surgery options provide similar GERD-related quality of life compared to traditional full or partial fundoplications with the added benefit of shorter operative time and faster recovery.

BACKGROUND: Peroral endoscopic myotomy (POEM) is a mainstay of treatment for achalasia. Tailored myotomy based on compliance, as measured with impedance planimetry (FLIP), has yet to be described. In this study we describe the associations between Eckardt score, postoperative GERD, and compliance. METHODS: A retrospective review of a prospectively maintained database was performed, evaluating patients who underwent POEM and intraoperative FLIP between January 2019 and November 2021. Group comparisons were made using two-tailed Wilcoxon rank-sum and Fisher's exact tests. Spearman's correlation coefficients (r) were used to assess the relationship between compliance and outcomes, all with two-tailed statistical significance of p < 0.05. RESULTS: Thirty five patients underwent POEM with intraoperative FLIP. At a 30 mL and 40 mL fill, respectively, compliance increased by 80% (180 ± 152%) and 77% (177 ± 131%) from pre to post myotomy. Mean Eckardt score improved from 5.5 ± 2.6 preoperatively to 1.3 ± 1.6 and 1.8 ± 1.9 at first and second follow up, respectively. Median times to first and second follow up were 22 days (IQR 16-23) and 65 days (IQR 58-142). A higher compliance at 40 mL fill was moderately associated with lower Eckardt score at first (r = -0.49, p = 0.012) and second (r = -0.64, p = 0.014) follow up. Post myotomy compliance ≥ 125 mm3/mmHg at 40 mL fill was associated with lower Eckardt scores, < 3, at first (0.4 ± 0.5 vs 1.8 ± 1.3, p = 0.008) and second (0.4 ± 0.5, vs 2.0 ± 1.4, p = 0.027) follow up. Compliance ≥ 125 mm3/mmHg performed better than previously defined ideal ranges of DI and CSA in predicting postoperative Eckardt scores. Compliance was not significantly associated with development of postoperative GERD. CONCLUSIONS: A target post myotomy compliance of ≥ 125 mm3/mmHg at a 40 mL fill is associated with normal Eckardt scores at first and second postoperative visits, and performs better than previously defined ideal ranges of DI and CSA in predicting post-operative Eckardt scores. Compliance is a poor predictor of developing GERD after POEM.

INTRODUCTION: Impedance planimetry (FLIP) provides objective feedback to optimize fundoplication outcomes. Ideal FLIP ranges for differing wraps and bougies have not yet been established. We report FLIP measurements during fundoplication grouped by choice of wrap and bougie with associated outcomes. METHODS: A retrospective review of a prospective gastroesophageal database was performed for all Nissen or Toupet fundoplication with intraoperative FLIP using an 8-cm catheter, 30-mL and/or 40-mL fill and/or 16-cm catheter, 60-mL fill. Surgeons used no bougie, the FLIP balloon as bougie, or a hard bougie. Outcomes included perioperative data, Reflux Symptom Index, GERD-HRQL, Dysphagia scores, need for dilation, postoperative EGD findings, and hernia recurrence. Group comparisons were made using two-tailed Kruskal-Wallis and Fisher's exact tests. RESULTS: Between 2016 and 2022, 333 patients underwent fundoplication and intraoperative FLIP. Procedures included Toupet with hard bougie (TFHB, N = 147), Toupet with FLIP bougie (TFFB, N = 69), Toupet without bougie (TFNB, N = 78), Nissen with hard bougie (NFHB, n = 20), or Nissen with FLIP bougie (NFFB, N = 19). FLIP measurements at 30-mL/40-mL fills varied significantly between groups, notably distensibility index at crural closure (CCDI) and post-fundoplication (FDI). No significant differences in FLIP measurements were seen between those who developed poor postoperative outcomes and those who did not, including when grouping by choice of wrap and bougie. At a 40-mL fill, abnormal motility patients with CCDI > 3.5 mm2/mmHg developed zero postoperative dysphagia. TFFB abnormal motility patients with CCDI > 3.5 mm2/mmHg or FDI > 3.6 mm2/mmHg developed zero postoperative dysphagia. CONCLUSION: Intraoperative FLIP measurements vary by fundoplication and bougie choice. A CCDI > 3.5 mm2/mmHg (40 mL fill) should be sought in abnormal motility patients, regardless of wrap or bougie, to avoid postoperative dysphagia. TFFB abnormal motility patients with FDI > 3.6 mm2/mmHg (40 mL fill) also developed zero postoperative dysphagia. FDI > 6.2 mm2/mmHg (40 mL fill) was seen in all postoperative hernia recurrences.

BACKGROUND: Mesh reinforced cruroplasty during laparoscopic paraesophageal hernia repair remains controversial due to wide variation in surgical technique and mesh composition. This study aims to review outcomes and rates of recurrence following laparoscopic paraesophageal hernia repair (LPEHR) with mesh reinforced cruroplasty utilizing absorbable mesh at a single institution. METHODS: A retrospective review of all patients who underwent LPEHR with mesh was performed. Medical records were reviewed for patient reported, radiographic or endoscopic evidence of recurrence, defined as > 2 cm of vertical intrathoracic stomach. If no studies were available for review, patients were considered to have no recurrence. Outcomes and mesh-related complications were also reviewed. RESULTS: Between 10/2008 and 9/2021, 473 patients underwent LPEHR with absorbable mesh; 1.3% type 2 hernias, 86.0% type 3 hernias, 12.7% type 4 hernias. Three types of mesh were used: initially biologic mesh (n = 83), then heavyweight synthetic bioabsorbable mesh (n = 261), and finally lightweight synthetic bioabsorbable mesh (n = 111). There were no significant differences in age, ASA, BMI, gender, smoking status, chronic steroid use, preoperative acid suppression, hernia type, or recurrent hernia between groups. There were no significant differences in 30-day postoperative outcomes. Reflux Symptom Index, GERD-HRQL, and Dysphagia Scores at 1- and 2-year postoperative timepoints were not significantly different. The overall recurrence rate was 16.7%, with no significant differences in recurrence rates between biologic, heavyweight or lightweight biosynthetic absorbable mesh through 2 years after surgery. A shorter median time to recurrence (10 months, p = 0.016) was seen in the lightweight group. CONCLUSION: LPEHR with absorbable mesh reinforced cruroplasty is feasible and safe, with equivalent patient-reported outcomes, including dysphagia, up to 2-years postop regardless of mesh choice. No significant differences in recurrence rates between biologic, heavyweight, or lightweight synthetic bioabsorbable mesh were seen up to 2 years after LPEHR.

BACKGROUND: As flexible endoscopy becomes an increasingly valuable minimally invasive approach to surgical challenges, an efficient and comprehensive training curriculum is needed to train surgeons in therapeutic endoscopy. We developed a modular curriculum utilizing a simulation-based, "into the fire" approach to endoscopic foreign body removal for practicing physicians with task performance pre- and post-testing. METHODS: From 2020 to 2021, two sessions of our advanced flexible endoscopy course were taught by two expert surgical endoscopists using ex-vivo porcine models. The course focused on safe removal techniques for various foreign bodies as part of an overall endoscopy curriculum that uses hands-on simulation-based pre-testing, didactics, and mentored practice sessions, followed by post-course examination. Pre- and post-course assessments and surveys were used to evaluate knowledge, performance, and confidence of participants, and subsequently analyzed using the Wilcoxon-signed rank test. RESULTS: Of the 16 practicing physicians who participated in the course, 43.8% were certified in Fundamentals of Endoscopic Surgery, and 62.5% had completed > 200 prior upper endoscopies. Upon course completion, scoring on knowledge-based written examinations improved from 3.4 ± 1.9 to 5.8 ± 2.0 (p < 0.001). Technical facility of each participant demonstrated significant overall improvement with post-course score increased from 15.8 ± 2.5 to 23.6 ± 1.6 (p < 0.001), with skill refinement noted in technical subcategories of appropriate instrument use (p < 0.001), foreign body manipulation (p < 0.001), and successful foreign body removal (p < 0.001). Confidence surveys likewise demonstrated significant increase in confidence after completion of the curriculum 11.6 ± 3.4 to 23.0 ± 5.5 (p < 0.001). CONCLUSIONS: The "into the fire" approach to teaching endoscopic foreign body removal utilizing our simulation module provides an effective curriculum to improve knowledge, confidence, and overall technical performance. Our methodology utilizes hands-on, simulation-based pre-testing prior to instruction. This introduces clinical scenarios and technical challenges, while accounting for and tailoring to provider-specific variation in knowledge and experience, facilitating training efficiency.

BACKGROUND: Despite the advantages of laparoscopic cholecystectomy, major bile duct injury (BDI) rates during this operation remain unacceptably high. In October 2018, SAGES released the Safe Cholecystectomy modules, which define specific strategies to minimize the risk of BDI. This study aims to investigate whether this curriculum can change the knowledge and behaviors of surgeons in practice. METHODS: Practicing surgeons were recruited from the membership of SAGES and the American College of Surgeons Advisory Council for Rural Surgery. All participants completed a baseline assessment (pre-test) that involved interpreting cholangiograms, troubleshooting difficult cases, and managing BDI. Participants' dissection strategies during cholecystectomy were also compared to the strategies of a panel of 15 experts based on accuracy scores using the Think Like a Surgeon validated web-based platform. Participants were then randomized to complete the Safe Cholecystectomy modules (Safe Chole module group) or participate in usually scheduled CME activities (control group). Both groups completed repeat assessments (post-tests) one month after randomization. RESULTS: Overall, 41 participants were eligible for analysis, including 18 Safe Chole module participants and 23 controls. The two groups had no significant differences in pre-test scores. However, at post-test, Safe Chole module participants made significantly fewer errors managing BDI and interpreting cholangiograms. Safe Chole module participants were less likely to convert to an open operation on the post-test than controls when facing challenging dissections. However, Safe Chole module participants displayed a similar incidence of errors when evaluating adequate critical views of safety. CONCLUSIONS: In this randomized-controlled trial, the SAGES Safe Cholecystectomy modules improved surgeons' abilities to interpret cholangiograms and safely manage BDI. Additionally, surgeons who studied the modules were less likely to convert to open during difficult dissections. These data show the power of the Safe Cholecystectomy modules to affect practicing surgeons' behaviors in a measurable and meaningful way.

BACKGROUND: Criteria to diagnose gastroesophageal reflux disease (GERD) vary. The American Gastroenterology Association (AGA) 2022 Expert Review on GERD focuses on acid exposure time (AET) rather than DeMeester score from ambulatory pH testing (BRAVO). We aim to review outcomes following anti-reflux surgery (ARS) at our institution, grouped by differing criteria for the diagnosis of GERD. METHODS: A retrospective review of a prospective gastroesophageal quality database was performed for all patients undergoing evaluation for ARS with preoperative BRAVO ≥ 48 h. Group comparisons were made using two-tailed Wilcoxon rank-sum and Fisher's exact tests and two-tailed statistical significance of p < 0.05. RESULTS: Between 2010 and 2022, 253 patients underwent an evaluation for ARS with BRAVO testing. Most patients (86.9%) met our institution's historical criteria: LA C/D esophagitis, Barrett's, or DeMeester ≥ 14.72 on 1+ days. Fewer patients (67.2%) met new AGA criteria: LA B/C/D esophagitis, Barrett's, or AET ≥ 6% on 2+ days. Sixty-one patients (24%) met historical criteria only, with significantly lower BMI, ASA, less hiatal hernias, and less DeMeester and AET-positive days, a less severe GERD phenotype. There were no differences between groups in perioperative outcomes or % symptom resolution. Objective GERD outcomes (need for dilation, esophagitis, and postop BRAVO) were equivalent between groups. Patient-reported quality of life scores, including GERD-HRQL, RSI, and Dysphagia Score did not differ between groups from preop through 1 year postop. Those who met our historical criteria only reported significantly worse RSI scores (p = 0.03) and worse GERD-HRQL scores at 2 years postop, though not statistically significant (p = 0.07). CONCLUSION: Updated AGA GERD guidelines exclude a portion of patients who historically would have been diagnosed with and surgically treated for GERD. This cohort appears to have a less severe GERD phenotype but equivalent outcomes up to 1 year, with more atypical GERD symptoms at 2 years postop. AET may better define who should be offered ARS than DeMeester score.

BACKGROUND AND AIMS: A small percentage of patients with esophageal dysmotility disorders (EDDs) fail to improve or relapse after management by laparoscopic Heller myotomy (LHM) and peroral endoscopic myotomy (POEM). In this study, we aimed to describe the role of functional luminal imaging probe (FLIP) in identifying patients who might benefit from lower esophageal sphincter (LES)-directed retreatment. METHODS: This was a retrospective study at 6 tertiary care centers (United States, 4; Europe, 1; Asia, 1) between January 2015 and April 2021 involving patients with prior failed myotomy. The primary outcome was the impact of the use of FLIP on the management of patients with prior failed myotomy. RESULTS: One hundred twenty-three patients (62 women [50%]; mean age, 53 ± 21.1 years) who underwent LHM (n = 53, 43%) or POEM (n = 70, 57%) for the management of achalasia (n = 98) or other EDDs (n = 25) had clinical failure at a median time of 10.8 months (interquartile range, .8-17.3) postprocedure. Twenty-nine patients had apposing "abnormal" diagnoses in terms of integrated relaxation pressure (IRP) >15 mm Hg on HRM and distensibility index (DI) <2.8 mm2/mm Hg on FLIP, with ultimate change in management noted in 15 patients (10 directed toward conservative management, 5 directed toward LES-directed retreatment). The impact of FLIP on both diagnosis and management was noted in 15 of 29 patients (52%). In the subgroup analysis of 44 patients who underwent LES-directed retreatment, clinical success was highest among patients with both abnormal IRP and DI (21/25 [84%]) versus patients with only abnormal IRP (8/14 [57%]) or only abnormal DI (3/5 [60%], P = .04), with DI at 40-mL distension volume on FLIP identified as an independent predictor of clinical success (odd ratio, 1.51; 95% confidence interval, 1.02-2.1; P = .03). CONCLUSIONS: The finding of this study further suggests the important role of using FLIP in addition to HRM in evaluating patients with clinical failure postmyotomy.

BACKGROUND: Treatment of Zenker's diverticulum has evolved from open surgery to endoscopic techniques, including flexible and rigid endoscopic septotomy, and more recently, peroral endoscopic myotomy (Z-POEM). This study compared the effectiveness of flexible and rigid endoscopic septotomy with that of Z-POEM. METHODS: Consecutive patients who underwent endoscopic septotomy (flexible/rigid) or Z-POEM for Zenker's diverticulum between 1/2016 and 9/2019 were included. Primary outcomes were clinical success (decrease in Dakkak and Bennett dysphagia score toâ≤â1), clinical failure, and clinical recurrence. Secondary outcomes included technical success and rate/severity of adverse events. RESULTS: 245 patients (110 females, mean age 72.63 years, standard deviation [SD] 12.37 years) from 12 centers were included. Z-POEM was the most common management modality (nâ=â119), followed by flexible (nâ=â86) and rigid (nâ=â40) endoscopic septotomy. Clinical success was 92.7â% for Z-POEM, 89.2â% for rigid septotomy, and 86.7â% for flexible septotomy (Pâ=â0.26). Symptoms recurred in 24 patients (15 Z-POEM during a mean follow-up of 282.04 [SD 300.48] days, 6 flexible, 3 rigid [Pâ=â0.47]). Adverse events occurred in 30.0â% rigid septotomy patients, 16.8â% Z-POEM patients, and 2.3â% flexible septotomy patients (Pâ<â0.05). CONCLUSIONS: There was no difference in outcomes between the three treatment approaches for symptomatic Zenker's diverticulum. Rigid endoscopic septotomy was associated with the highest rate of complications, while flexible endoscopic septotomy appeared to be the safest. Recurrence following Z-POEM was similar to flexible and rigid endoscopic septotomy. Prospective studies with long-term follow-up are required.
