RESUMO
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± â13.4 years and BMI of 30.2 â± â5.7 âkg/m2. Repairs predominantly utilized synthetic mesh in the preperitoneal space (95.1 â%). After 29.9 â± â13.1 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.
RESUMO
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.
RESUMO
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.
RESUMO
This systematic review evaluates the fragility of randomized clinical trials that used mesh in abdominal wall reconstruction.
