RESUMEN
BACKGROUND: It has been reported that higher surgeon experience leads to better patient outcomes. In this study, we look at surgeon experience and its association with postoperative outcomes and variation among the practice of surgeons performing paraesophageal hernia repairs (PEH). METHOD: This was a retrospective study of 1155 patients who underwent PEH repair at a single institution (2010-2023). Surgeon experience was defined as the number of surgeries performed per surgeon and was split using the median surgeries (n = 100), with surgeons performing at or above the median categorized as high-experience and below the median as low-experience surgeons. A multivariable logistic regression model was used to test correlation between surgeon experience and variables, including demographics and intra- and post-operative outcomes. RESULTS: High-experience surgeons performed more elective cases (93.4% vs 85.5%), but low-experience surgeons operated more on emergent (2.7% vs 0.9%), semi-elective (2.3% vs 1.4%), and urgent cases (9.5% vs 4.3%). Low-experience surgeons operated more on patients who were older (67.5 vs 63.2 years, p < 0.001) and had an increased risk of CVD (72.9% vs 61.5%, p < 0.001). Intraoperative OR time was considerably less for high-experience surgeons (115.8 vs 172.9 min, p < 0.001). Low-experience surgeons had increased risk of intra-operative complications (4.5% vs 1.8%, p = 0.021) and post-op pneumonia within 30 days (1.8% vs 0.3%). However, long-term outcomes such as hernia recurrence (OR: 1.10, CI: 0.78-1.54) and redo-operations for hiatal hernia (OR: 1.10, CI: 0.65-1.75) were similar for both groups. CONCLUSION: High-experience surgeons perform more complex revisional surgeries in less time with fewer complications. Low-experience surgeons operated more on patients with higher comorbidities but had significantly higher OR times. Long-term results of recurrence and redo-operations were comparable. These variations suggest that high-experience surgeons are more efficient while operating on more complex cases. These findings have pivotal implications to facilitate mentorship and education among less-experienced surgeons.
RESUMEN
BACKGROUND: Per oral endoscopic myotomy (POEM) is a safe therapy for the treatment of achalasia. Long-term effects of untreated achalasia include worsening dysmotility and disruptions in esophageal anatomy, i.e., tortuosity and dilation. We hypothesize that long-standing achalasia prior to intervention will have worse outcomes following POEM than in patients with symptoms for shorter duration. METHODS: We retrospectively analyzed achalasia patients who underwent POEM at our institution from 2011 to 2023, categorizing them into symptom duration cohorts (< 1 year, 1-3 years, 4-10 years, > 10 years). Inclusion criteria comprised patients with documented achalasia diagnosis who received POEM treatment at our facility. Exclusion criteria encompassed individuals lacking data pertaining to achalasia diagnosis, the time frame before intervention, or those missing pre and postoperative Eckardt scores. POEM failure was defined as symptom recurrence, necessity for repeat intervention, or high postoperative Eckardt score. We compared demographic, preoperative, and postoperative outcomes across these cohorts, and employed multivariable logistic regression to explore the link between symptom duration and POEM response. RESULTS: During the study period, in our increased cohort 234 patients met inclusion criteria. 75 patients had symptoms for < 1 year, 78 patients had symptoms from 1 to 3 years, 47 patients had symptoms from 4 to 10 years, and 34 patients had symptoms > 10 years. Patient demographics such as age, sex, BMI, Charleson-Deyo-Comorbidity-Index, and diabetes did not differ amongst cohorts. High-resolution manometry data, including achalasia type, Median IRP, LES residual pressure, and Basal LES pressure did not differ between groups. Preoperative Eckardt scores ranged from 4 to 5 across groups (p 0.24). Patients endorsed an average of three total preoperative symptoms across groups (p 0.13). Patients with symptoms greater than 4 years had significantly more endoscopic interventions prior to POEM (37% vs, 68% p .001). There was no significant difference in post-procedure mean Eckardt scores between cohorts. All cohorts experienced the same number of post-POEM symptoms. Post-POEM manometric measurements remained consistent across cohorts. Similarly, there were no significant differences in terms of symptom recurrence, requirement for repeat interventions, or repeat POEM among the cohorts. Multivariable logistic regression analysis determined achalasia symptoms greater than a decade did not result in increased odds of having a higher postoperative Eckardt score, worse dysphagia, regurgitation, or weight loss. CONCLUSIONS: In this increased cohort, this data once again suggests that longer symptom duration is not associated with increased rates of POEM failure.
RESUMEN
INTRODUCTION: The routine use of post-operative esophogram has come under evaluation for multiple upper GI surgeries such as with bariatric surgery and gastric resections. A major complication following Per Oral Endoscopic Myotomy (POEM) is a leak from the myotomy site. A post-operative contrast esophogram is often utilized to evaluate the presence of a leak, however it is not a standardized care practice for all patients. Presently it is selectively performed depending on physician assessment intra-operatively. This project will evaluate the necessity of post-operative contrast esophogram following POEM. MATERIALS AND METHODS: We retrospectively reviewed 277 patients diagnosed with achalasia who underwent POEM by two surgeons from 2011 to 2022. 173 patients met the inclusion criteria. A post-operative esophogram was used for the evaluation of a leak. Post-operative esophagram were selectively performed on day 1 following surgery using a water-soluble material. Data was evaluated using Stata. RESULTS: There were 3 detected leaks in the group that underwent esophagrams compared to the non-esophagram group in the early post-operative period. The overall complication rate was 5.5% in the non-esophagram versus 7.9% in the esophagram group. Length of stay was 1.48 days in the non-UGI vs 1.76 days in the esophagram group. Readmission rate was 10.9% in non-esophagram versus 8.7% in esophagram group. CONCLUSION: There was no statistically significant difference in outcomes in patients undergoing POEM who received post-operative esophagram verses patients who did not receive post-operative esophagram. The routine use of a contrast esophogram to detect a leak following POEM may not be justified. This study suggests that esophagrams should be performed depending on the clinical signs/symptoms post-operatively that would warrant imaging and intervention.
RESUMEN
OBJECTIVE: There are few assessments of the competence and growth of surgical residents as educators. We developed and piloted an observation-based feedback tool (FT) to provide residents direct feedback during a specific teaching session, as perceived by medical students (MS). We hypothesized that residents' performance would improve with frequent, low stakes, observation-based feedback. SETTING: This prospective study took place at an academic general surgery program. PARTICIPANTS: Focus groups of MS, surgical residents, and faculty informed FT development. MS completed the FT regarding resident teaching. DESIGN: The FT utilized 5 slider-bar ratings (0 to 100) about the teaching encounter and a checklist of 16 desirable teaching behaviors. QR codes and weekly email links were distributed for 12 months (6 clerkship blocks) to promote use. Residents were sent their results after each block. A survey after each block assessed motivation for use and gathered feedback on the FT. Descriptive statistics were used for analysis (medians, IQRs). Primary measures of performance were median of the slider-bar scores and the number of teaching behaviors. RESULTS: The FT was used 111 times; 37 of 46 residents were rated by up to 65 MS. The median rating on the slider-bars was 100 and the median number of desirable teaching behaviors was 12; there were no differences based on gender or PGY level. 10 residents had 5 or more FT observations during the year. Four residents had evaluations completed in 4 or more blocks and 19 residents had evaluations completed in at least 2 blocks. Over time, 13 residents had consistent slider-bar scores, 1 resident had higher scores, and 5 residents had lower scores (defined as a more than 5-point change from initial rating). Frequency of use of the FT decreased over time (38, 32, 9, 21, 7, 5 uses per block). The post-use survey was completed by 24 MS and 19 residents. Most common reasons for usage were interest in improving surgical learning environment, giving positive feedback (MS), and improving teaching skills (residents). Most common reasons for lack of usage from residents were "I did not think I taught enough to ask for feedback," "I forgot it existed," and "I did not know it existed." CONCLUSIONS: The FT did not lead to any meaningful improvement in resident scores over the course of the year. This may be due to overall high scores, suggesting that the components of the FT may require reevaluation. Additionally, decreased utilization of the instrument over time made it challenging to assess change in performance of specific residents, likely due to lack of awareness of the FT despite frequent reminders. Successful implementation of observation-based teaching assessments may require better integration with residency or clerkship objectives.

AIM: The heterogeneity in data quality presented in studies regarding Crohn's anal fistula (CAF) limit extrapolation into clinical practice. The ENiGMA collaborators established a core descriptor set to standardize reporting of CAF. The aim of this work was to quantify the use of these descriptors in recent literature. METHOD: We completed a systematic review of PubMed and the Cochrane Library, extracting publications from the past 10 years specific to the clinical interventions and outcomes of CAF, and reported in line with PRISMA guidance. Each article was assessed for inclusion of ENiGMA descriptors. The median number of descriptors per publication was evaluated along with the overall frequency of each individual descriptor. Use of ENiGMA descriptors was compared between medical and procedural publications. RESULTS: Ninety publications were included. The median number of descriptors was 15 of 37; 16 descriptors were used in over half of the publications while 17 were used in fewer than a third. Descriptors were more frequently used in procedural (n = 16) than medical publications (n = 14) (p = 0.031). In procedural publications, eight descriptors were more frequently used including Faecal incontinence, Number of previous fistula interventions, Presence and severity of anorectal stenosis and Current proctitis. Medical publications were more likely to include Previous response to biological therapy and Duration and type of current course of biological therapy. CONCLUSION: With many descriptors being used infrequently and variations between medical and procedural literature, the colorectal community should assess the need for all 37 descriptors.

BACKGROUND: It is unclear how patients with anal fissures are treated in real-world settings, particularly since patients may not see colorectal surgeons. This study describes trends in treatment with medical therapies (calcium-channel blockers [CCBs], nitroglycerin [NTG], and narcotics) and surgical treatments. METHODS: Cohorts were created within the TriNetX database platform using codes for anal fissures and surgical interventions. Demographics were compared between patients that received surgical intervention within 1 year of diagnosis, CCB or NTG within 1 year (or preoperatively), or narcotics within 30 days or postoperatively vs those who did not. RESULTS: 121,213 patients were included of which 4.0% had surgical intervention. Factors associated with surgical intervention were male sex (OR 1.40), White race (OR 1.17), and Hispanic ethnicity (OR 1.11). Male patients were more likely to undergo sphincterotomy (OR 1.49). Female (OR 1.27), non-Hispanic (OR 1.34), and White patients (OR 1.41) were more likely to have chemodenervation. Regarding nonoperatively managed patients, non-Hispanic (OR .91) and White patients (OR .89) were less likely to receive CCB/NTG. Male (OR 1.21), non-Hispanic (OR 1.08), and Black patients (OR 1.20) were more likely to receive narcotics. Male patients that required surgery were more likely to be prescribed CCB/NTG preoperatively (OR 1.27). Non-Hispanic surgical patients were more likely to receive narcotics (OR 1.84). DISCUSSION: Male fissure patients were more likely to undergo surgical intervention other than chemodenervation. Differences in the rates of surgery and medical therapy (especially narcotics) between races and ethnicities require exploration to enhance the care of patients with anal fissures.

BACKGROUND: Per oral endoscopic myotomy (POEM) has been shown to be an efficacious and safe therapy for the treatment of achalasia. Compared to laparoscopic Heller myotomy however, no antireflux procedure is routinely combined with POEM and therefore the development of symptomatic or silent reflux is of concern. This study was designed to determine if various patient factors and anatomy would predict the development of gastroesophageal reflux disease post-operatively. METHODS: This was a retrospective cohort study of all patients who underwent a POEM at a single institution by a single surgeon over an eight-year period (2014-2022). It has been our practice to obtain a postoperative ambulatory pH test on all patients 6 months after POEM off all acid reducing medications. Patients without a postoperative ambulatory esophageal pH monitoring test were excluded. Age, sex, obesity (BMI > 30), achalasia type, presence of a hiatal hernia, history of prior endoscopic achalasia treatments or myotomy were analyzed using univariate analysis as predictive factors for the development of postoperative GERD (DeMeester score > 14.7 on ambulatory pH monitoring). RESULTS: There were 179 total patients included in the study with 42 patients (23.5%) having undergone postoperative ambulatory pH testing. The majority of patients (137 or 76.5%) were lost to follow up and did not undergo ambulatory pH testing. Twenty-three out of those 42 patients (55%) had evidence of GERD on ambulatory pH testing. Multiple preoperative patient characteristics including demographics, manometric results, EGD findings, and history of prior achalasia interventions did not correlate with the development of post-operative GERD. CONCLUSIONS: Despite the high rate of reflux after POEM, there does not appear to be any reliable preoperative indicators of which patients have a higher risk of developing post-operative GERD after POEM.

BACKGROUND: While per oral endoscopic myotomy (POEM) has been shown to be efficacious in the treatment of achalasia, it can be difficult to predict who will have a robust and durable response. Historically, high lower esophageal sphincter pressures have been shown to predict a worse response to endoscopic therapies such as botox therapy. This study was designed to evaluate if modern preoperative manometric data could predict a response to therapy after POEM. METHODS: This was a retrospective study of 144 patients who underwent a POEM at a single institution by a single surgeon over an 8-year period (2014-2022) who had high-resolution manometry performed preoperatively and had an Eckardt symptom score performed both preoperatively and postoperatively. The achalasia type and integrated relaxation pressures (IRP) were then tested for potential correlation with need for any further achalasia interventions postoperatively as well as the degree of Eckardt score reduction using univariate analysis. RESULTS: The achalasia type on preoperatively manometry was not predictive of need for further interventions or degree of Eckardt score reduction (p = 0.74 and 0.44, respectively). A higher IRP was not predictive of need for further interventions however it was predictive of a greater reduction in postoperative Eckardt scores (p = 0.03) as shown by a nonzero regression slope. CONCLUSION: In this study, achalasia type was not a predictive factor in need for further interventions or degree of symptom relief. While IRP was not predictive of need for further interventions, a higher IRP did predict better symptomatic relief postoperatively. This result is opposite that of other endoscopic treatment modalities. Therefore, patients with higher IRP on high-resolution manometry would likely benefit from myotomy which provides significant symptomatic relief postoperatively.

BACKGROUND: Studies assessing outcomes of patients undergoing peroral endoscopic myotomy (POEM) after botulinum injection or dilation have had various results with respect to failure, although this has not been differentiated between lack of clinical response and recurrence. We hypothesize that patients with previous endoscopic intervention(s) are more likely to recur than treatment-naïve patients. METHODS: This is a retrospective cohort study of patients that underwent POEM for achalasia at a single tertiary care center between 2011 and 2022. Patients were excluded if they had previous myotomy (POEM or Heller). The remaining patients were stratified into treatment-naïve patients (TN), those with previous botulinum injection (BTX), those with previous dilatation (BD), and those with both previous endoscopic interventions (BOTH). Primary outcome was recurrence indicated by clinical symptoms or need for repeat endoscopic intervention or surgery after originally having clinical resolution (Eckardt ≤ 3). Multivariate logistic regression using preoperative and intraoperative factors was completed to assess odds of recurrence. RESULTS: A total of 164 patients were included in the analysis, 90 TN, 34 BD, 28 BTX, and 12 BOTH. There were no other significant differences in demographics or in preoperative Eckardt score (p = 0.53). There was no difference in the proportion of patients that had postoperative manometry (p = 0.74), symptom recurrence (p = 0.59), surgical intervention (p = 0.16). BTX (14.3%) and BOTH (16.7%) patients had a higher rate of repeat endoscopic intervention than BD and TN patients (5.9% and 1.1%). In the logistic regression analysis, there was no association among the BTX, BD, or BOTH groups compared to the TN group. No odds ratios achieved statistical significance. CONCLUSIONS: There were no increased likelihood of recurrence with botulinum injection or dilatation prior to POEM, implying that they are similarly good candidates compared to treatment-naïve patients.

BACKGROUND: Malignant bowel obstruction (MBO) is a sequela of advanced intraabdominal cancer and has a profound impact on quality of life. Common therapy is endoscopic decompressive gastrostomy tube placement. Standard gastrostomy tubes are poorly designed to completely evacuate the dependent portions of the stomach due to their location on the anterior gastric wall. In our institution we have begun placing the ASPIRE Assist gastrostomy tube (ASPIRE Bariatrics, Exton, PA) which includes a 15 cm long, 30Fr fenestrated gastric tube extension for enhanced gastric decompression. This tube is FDA indicated for gastric decompression and marketed for endoscopic weight loss. The purpose of this study is to review our experience managing MBO utilizing the ASPIRE Assist tube. METHODS: This is a retrospective analysis of outcomes at a single institution. All decompressive endoscopic gastrostomy tubes placed by two surgeons between November 2019 and July 2021 were reviewed. Endoscopic placement was performed utilizing standard safe tract and Ponsky pull techniques. RESULTS: Fourteen patients were identified (10F:4 M), mean age 70 (range 35-89). Primary cancer diagnoses included gynecologic (8), colorectal (3), bladder (1), small bowel (1), peritoneal serous (1). During the 12 months before decompressive gastrostomy tube placement, mean number of hospital admissions for MBO was 1.6 (range 1-3). Following tube placement, twelve patients had no further hospital admissions for MBO over their lifespan of mean 270 days (range 8-679 days). One patient had 1 admission for MBO in the 12 months before tube placement and 3 admissions in the 4 months after placement. A second patient had 2 admissions in the 12 months before tube placement and 1 admission in their 54-day lifespan after placement. There were no major complications. CONCLUSIONS: Endoscopic placement of the ASPIRE Assist gastrostomy tube is safe for palliation of MBO and may improve gastric decompression compared with standard endoscopic gastrostomy tubes. Enhanced gastric decompression can better manage symptoms, reduce hospital encounters, and improve quality of life. Further study is needed, however, our initial data appears promising.
