Cricopharyngomyotomy: Outcomes of flexible endoscopic management of small and medium sized Zenker's diverticulum.

BACKGROUND: Zenker's diverticulum (ZD) was historically treated with an open transcervical myotomy with diverticulectomy, but endoscopic approaches have gained popularity, though with little recent data. This study aimed to report flexible endoscopic cricopharyngomyotomy (FEC) outcomes, particularly in smaller diverticula. METHODS: Patients with ZD treated with FEC at a tertiary center were reviewed. Patients were grouped by diverticulum size: small (sZD)≤1.5 â€‹cm; medium (mZD) â€‹> â€‹1.5 â€‹cm. RESULTS: Of 30 patients, median age, BMI, sex, and comorbidities were similar between sZD (n â€‹= â€‹18) and mZD (n â€‹= â€‹12). Overall, 80.0 â€‹% had the procedure performed with a needle knife. Median number of clips for mucosotomy closure (5.0[5.0,6.0]vs.7.0[5.0,7.0]clips;p â€‹= â€‹0.051), operative time (59.5[51.0,75.0]vs.74.5[51.0,93.5]minutes;p â€‹= â€‹0.498), length-of-stay (1.0[1.0,1.0]vs.1.0[1.0,1.0]days;p â€‹= â€‹0.397), and follow-up (20.8[1.1,33.4]vs.15.6[5.4,50.4]months;p â€‹= â€‹0.641) were comparable. There were no postoperative leaks; incomplete myotomy occurred in one sZD, yielding a clinical success rate of 96.7 â€‹%. CONCLUSIONS: FEC has a high success rate for ZD and an advantage in small diverticula, difficult to treat with stapling or open technique.

Racial and Socioeconomic Disparities in Complex Abdominal Wall Reconstruction Referrals.

Background: Health disparities are pervasive in surgical care. Particularly racial and socioeconomic inequalities have been demonstrated in emergency general surgery outcomes, but less so in elective abdominal wall reconstruction (AWR). The goal of this study was to evaluate the disparities in referrals to a tertiary hernia center. Methods: A prospectively maintained hernia database was queried for patients who underwent open ventral hernia (OVHR) or minimally invasive surgical (MISR) repair from 2011 to 2022 with complete insurance and address information. Patients were divided by home address into in-state (IS) and out-of-state (OOS) referrals as well as by operative technique. Demographic data and outcomes were compared. Standard and inferential statistical analyses were performed. Results: Of 554 patients, most were IS (59.0%); 334 underwent OVHR, and 220 underwent MISR. IS patients were more likely to undergo MISR (OVHR: 45.6% vs. 81.5%, laparoscopic: 38.2% vs. 14.1%, robotic: 16.2% vs. 4.4%; p < 0.001) when compared to OOS referrals. Of OVHR patients, 44.6% were IS and 55.4% were OOS. Patients' average age and BMI, sex, ASA score, and insurance payer were similar between IS and OOS groups. IS patients were more often Black (White: 77.9% vs. 93.5%, Black: 16.8% vs. 4.3%; p < 0.001). IS patients had more smokers (12.1% vs. 3.2%; p = 0.001), fewer recurrent hernias (45.0% vs. 69.7%; p < 0.001), and smaller defects (155.7 ± 142.2 vs. 256.4 ± 202.9 cm2; p < 0.001). Wound class, mesh type, and rate of fascial closure were similar, but IS patients underwent fewer panniculectomies (13.4% vs. 34.1%; p < 0.001), component separations (26.2% vs. 51.4%; p < 0.001), received smaller mesh (744.2 ± 495.6 vs. 975.7 ± 442.3 cm2; p < 0.001), and had shorter length-of-stay (4.8 ± 2.0 vs. 7.0 ± 5.5 days; p < 0.001). There was no difference in wound breakdown, seroma requiring intervention, hematoma, mesh infection, or recurrence; however, IS patients had decreased wound infections (2.0% vs. 8.6%; p = 0.009), overall wound complications (11.4% vs. 21.1%; p = 0.016), readmissions (2.7% vs. 13.0%; p = 0.001), and reoperations (3.4% vs. 11.4%; p = 0.007). Of MISR patients, 80.9% were IS and 19.1% were OOS. In contrast to OVHR, MISR IS and OOS patients had similar demographics, preoperative characteristics, intraoperative details, and postoperative outcomes. Conclusion: Although there were no differences in referred patients for MISR, this study demonstrates the racial disparities that exist among our IS and OOS complex, open AWR patients. Awareness of these disparities can help clinicians work towards equitable access to care and equal referrals to tertiary hernia centers.

The Utilization of Laparoscopic Ventral Hernia Repair (LVHR) in Incarcerated and Strangulated Cases: A National Trend in Outcomes.

INTRODUCTION: Early after its adoption, minimally invasive surgery had limited usefulness in emergent cases. However, with improvements in equipment, techniques, and skills, laparoscopy in complex and emergency operations expanded substantially. This study aimed to examine the trend of laparoscopy in incarcerated or strangulated ventral hernia repair (VHR) over time. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was queried for laparoscopic repair of incarcerated and strangulated hernias (LIS-VHR) and compared over 2 time periods, 2014-2016 and 2017-2019. RESULTS: The utilization of laparoscopy in all incarcerated or strangulated VHR increased over time (2014-2016: 39.9% (n = 14 075) vs 2017-2019: 46.3% (n = 18 369), P < .001). Though likely not clinically significant, demographics and comorbidities statistically differed between groups (female: 51.7% vs 50.0%, P = .003; age 54.5 ± 13.7 vs 55.4 ± 13.8 years, P < .001; BMI 34.9 ± 8.0 vs 34.6 ± 7.8 kg/m2, P < .001). Patients from 2017 to 2019 were less comorbid (18.9% vs 16.8% smokers, P < .001; 18.2% vs 17.3% diabetic, P = .036; 4.6% vs 4.1% COPD, P = .021) but had higher ASA classification (III: 43.3% vs 45.7%; IV: 2.5% vs 2.7%, P < .001). Hernia types (primary, incisional, recurrent) were similar in each group. Operative time (89.7 ± 59.3 vs 97.4 ± 63.4 min, P < .001) became longer but length-of-stay (1.4 ± 3.3 vs 1.1 ± 2.6 days, P < .001) decreased. There was no statistical difference in surgical complications, medical complications, reoperation, or readmission rates between periods. CONCLUSION: Laparoscopic VHR has become a routine method for treating incarcerated and strangulated hernias, and its utilization continues to increase over time. Clinical outcomes have remained the same while hospital stays have decreased.

Open repair of flank and lumbar hernias: 142 consecutive repairs at a high-volume hernia center.

BACKGROUND: Flank and lumbar hernias (FLH) are challenging to repair. This study aimed to establish a reproducible management strategy and analyze elective flank and lumbar repair (FLHR) outcomes from a single institution. METHODS: A prospective analysis using a hernia-specific database was performed examining patients undergoing open FLHR between 2004 and 2021. Variables included patient demographics and operative characteristics. RESULTS: Of 142 patients, 106 presented with flank hernias, and 36 with lumbar hernias. Patients, primarily ASA Class 2 or 3, exhibited a mean age of 57.0 â€‹± â€‹13.4 years and BMI of 30.2 â€‹± â€‹5.7 â€‹kg/m2. Repairs predominantly utilized synthetic mesh in the preperitoneal space (95.1 â€‹%). After 29.9 â€‹± â€‹13.1 months follow-up, wound infections occurred in 8.3 â€‹%; hernia recurrence was 3.5 â€‹%. At 6 months postoperatively, 21.2 â€‹% of patients reported chronic pain with two-thirds of these individuals having preoperative pain. CONCLUSIONS: Open preperitoneal FLHR provides a durable repair with low complication and hernia recurrence rates over 2.5 years of follow-up.

Factors Associated With Respiratory Failure After Open Ventral Hernia Repair: An Evaluation of the NSQIP Database.

An analysis of ACS-NSQIP open ventral hernia repair (OVHR) data (2017-2019) was performed. Respiratory failure (RF) occurred in 643 patients (1%) and not in 63,213 (99%) (nRF). Respiratory failure patients were older (63.7 vs 57 years, P < .001) and more comorbid: insulin-dependent diabetes (14.7% vs 5.8%, P < .001), COPD (19.4% vs 5.2%, P < .001), BMI (36.0 vs 32.8, P < .001), and current tobacco use (24.9% vs 17.6%, P < .001). Respiratory failure patients had greater ASA scores (ASA 3: 63.3% vs 47.8%, P < .001), bowel resection (8.2% vs 1.3%, P < .001), component separation (20.1% vs 9.0%, P < .001), operative times (178.4 vs 98.8 minutes, P < .001), complications (deep wound infections 3.6% vs 1.0%, organ space infections 13.2% vs 1.0%, wound dehiscence 3.1% vs 0.6%, acute renal failure 11.7% vs 0.1%), and hospital stay (13.7 vs 2.3 days), with fewer home discharges (44.3% vs 96.4%) (all P < .001). Respiratory failure patients had higher mortality compared to nRF (20.2% vs 0.1%, P < .001). Respiratory failure after OVHR is rare but correlates closely with significant wound, systemic, and social complications. Preoperative management of risk factors would be appropriate in high-risk patients.
