Sarcopenia in Patients Undergoing Open Ventral Hernia Repair.

Radiologic indicators of sarcopenia have been associated with adverse operative outcomes in some surgical populations. This study assesses the association of radiologic indicators of frailty with outcomes after open ventral hernia repair (OVHR). A prospective, institutional, hernia-specific database was queried for patients undergoing OVHR from 2007 to 2018 with preoperative CT. Psoas muscle cross-sectional area at L3 was measured and adjusted for height (skeletal muscle index (SMI)). L3 vertebral body density (L3 VBD) was measured. Demographics and outcomes were evaluated as related to SMI and L3 VBD. Of 1178 patients, 9.7 per cent of females and 15.8 per cent of males had sarcopenia and 11.6 per cent of females and 9.2 per cent of males had osteopenia. Neither sarcopenia nor osteopenia were associated with outcomes of wound infection, readmission, reoperation, hernia recurrence, or major complications. When examined as continuous variables or by quartile, SMI and L3 VBD were not associated with adverse outcomes, including in subsets of male or female patients, the elderly, contaminated cases, and the obese. Radiologic markers of sarcopenia and osteopenia are not associated with adverse outcomes after OVHR. Further study should examine age or other potential predictors of outcomes in this patient population, such as independent status.

Mesh reinforcement of paraesophageal hernia repair: Trends and outcomes from a national database.

BACKGROUND: Placement of paraesophageal type of "mesh" in paraesophageal hernia repair is controversial. This study examines the trends and outcomes of mesh placement in paraesophageal hernia repair. METHODS: The American College of Surgeons National Surgical Quality Improvement Program was queried for patients who underwent paraesophageal hernia repair with or without mesh (2010-2017). Demographics, operative approach, and outcomes were compared over time. RESULTS: Of 25,801, most paraesophageal hernia repair cases were elective (89.3%), without mesh (61.9%), and performed laparoscopically (91.3%).When compared with open paraesophageal hernia repair patients, the patients undergoing laparoscopic paraesophageal hernia repair had lesser rates of reoperation, readmission, mortality, overall complications and major complications (2.7% vs 4.8%, 6.2% vs 9.6%, 0.6% vs 2.9%, 7.1% vs 21.3%, 3.8% vs 11.1%, respectively; all P < .0001). Mesh placement was more common in laparoscopic paraesophageal hernia repair (38.9 vs 29.7, P < .0001) than opern paraesophageal hernia repair. During 2010-2017, mesh placement decreased from 46.2% to 35.2% of laparoscopic paraesophageal hernia repair (P < .0001). Operative times for laparoscopic paraesophageal hernia repair decreased over time, and laparoscpic paraesophageal hernia repair without mesh was consistently less (with mesh: 176.0 ± 71.0 to 149.9 ± 72.5 min, without mesh: 148.6 ± 71.4 to 134.6 ± 70.4). We observed no changes in comorbidities or adverse outcomes over time. Using multivariate analysis to control for potential confounding factors, chronic obstructive pulmonary disease was associated most strongly with adverse outcomes, including mortality (OR 2.53, CI 1.55-4.14), any complications (OR 1.80, CI 1.51-2.16), major complications (OR 1.80, CI 1.51-2.16), readmission (OR 1.63, CI 1.33-1.99) and reoperation (OR 1.49, CI 1.10-2.02). Mesh placement was not associated with adverse outcomes. CONCLUSION: The placement of mesh during laparoscopic paraesophageal hernia repair is not associated with adverse outcomes. Use of mesh with laparoscopic paraesophageal hernia repair is decreasing with no apparent adverse impact on short-term patient outcomes. Further research is needed to investigate patient factors not captured by this national database, such as characteristics of the hernia, patient symptoms, and hernia recurrence.

Short-term Outcomes of Esophagectomies in Octogenarians-An Analysis of ACS-NSQIP.

BACKGROUND: In the face of an increasingly aged population, surgical management in the elderly will rise. This study assesses the short-term outcomes of esophagectomies in octogenarians. MATERIAL AND METHODS: The National Surgical Quality Improvement Program database was queried for esophagectomy cases from 2005 to 2014. Patients aged <80 and ≥80 y were compared in univariate and multivariate analysis, controlling for confounding variables. RESULTS: Among 9354 esophagectomies, 4.3% were performed in patients aged ≥80 y. Ivor Lewis was the most common approach, comprising 43% of cases. Octogenarians more frequently had dependent functional status (P < 0.0001) and cardiovascular disease (P < 0.0001), whereas younger patients were more likely obese (P < 0.0001), smokers (P < 0.0001), and have excess preoperative weight loss (P = 0.0043). Compared to younger patients, in multivariate analysis, elderly patients were noted to have increased risk of 30-d mortality (odds ratio [OR] 1.67; confidence interval [CI] 1.03-2.67), discharge to facility (OR 3.08; CI 2.36-4.02), myocardial infarction (OR 2.49; CI 1.29-4.82), and pneumonia (OR 1.47; CI 1.12-1.910). However, regardless of age, dependent functional status demonstrated the strongest association with mortality (OR 3.41; CI 2.14-6.61). Within the elderly, each additional year above 80 y old increased the risk of discharge to a facility by 17% (OR 1.17; CI 1.04-1.30). Cases requiring nongastric intestinal conduit were also more likely to suffer from early mortality (OR 2.87; CI 1.87-4.40). CONCLUSIONS: Age is independently associated with multiple adverse outcomes, including mortality, discharge to facility, and postoperative cardiopulmonary complications. Functional dependence is even more so associated with poor outcomes. Careful selection of very elderly patients is required to minimize additional risk.

MELD-Na Score as a Predictor of Anastomotic Leak in Elective Colorectal Surgery.

BACKGROUND: For cirrhotic patients awaiting liver transplantation, the Model for End-Stage Liver Disease Sodium (MELD-Na) model is extensively studied. Because of the simplicity of the scoring system, there has been interest in applying MELD-Na to predict patient outcomes in the noncirrhotic surgical patient, and MELD-Na has been shown to predict postoperative morbidity and mortality after elective colectomy. Our aim was to identify the utility of MELD-Na to predict anastomotic leak in elective colorectal cases. METHODS: The American College of Surgeons National Surgical Quality Improvement Program targeted colectomy database was queried (2012-2014) for all elective colorectal procedures in patients without ascites. Leak rates were compared by MELD-Na score using chi-square tests and multivariate logistic regression analysis. RESULTS: We identified 44,540 elective colorectal cases (mean age, 60.5 y ± 14.4, mean body mass index 28.8 ± 6.6 kg/m2, 52% female), of which 70% were colon resections and 30% involved partial rectal resections (low anterior resections). Laparoscopic approach accounted for 64.72% while 35.3% were open. The overall complication and mortality rates were 21% and 0.7%, respectively, with a total anastomotic leak rate of 3.4%. Overall, 98% had a preoperative MELD-Na score between 10 and 20. Incremental increases in MELD-Na score (10-14, 15-19, and ≥20) were associated with an increased leak rate, specifically in partial rectal resections (3.9% versus 5.1% versus 10.7% P <0.028). MELD-Na score ≥20 had an increased leak rate when compared with those with MELD-Na 10-14 (odds ratio [OR] 1.627; 95% confidence interval [CI] [1.015, 2.607]). An MELD-Na score increase from 10-14 to 15-19 increases overall mortality (OR 5.22; 95% CI [3.55, 7.671]). In all elective colorectal procedures, for every one-point increase in MELD-Na score, anastomotic leak (OR 1.04 95% CI [1.006, 1.07]), mortality (OR 1.24; 95% CI, [1.20, 1.27]), and overall complications (OR 1.10; 95% CI [1.09, 1.12]) increased. MELD-Na was an independent predictor of anastomotic leak in partial rectal resections, when controlling for gender, steroid use, smoking, approach, operative time, preoperative chemotherapy, and Crohn's disease (OR 1.06, 95% CI [1.002, 1.122]). CONCLUSIONS: MELD-Na is an independent predictor of anastomotic leak in partial rectal resections. Anastomotic leak risk increases with increasing MELD-Na in elective colorectal resections, as does 30-d mortality and overall complication rate. As MELD-Na score increases to more than 20, restorative partial rectal resection has a 10% rate of anastomotic leak.

Predictive modeling for chronic pain after ventral hernia repair.

BACKGROUND: Few studies predict which patients have dissolution of their postoperative discomfort or develop chronic pain after ventral hernia repair (VHR). This study develops a predictive model to determine which patients are at the greatest risk of chronic pain after VHR. METHODS: A prospective study of VHR patients was performed via the International Hernia Mesh Registry. Anonymous, self-reported, quality of life data using the Carolinas Comfort Scale (CCS) was recorded preoperatively, and 1,6, and 12 months postoperatively. Pain was identified as a score of 2 or more (mild but bothersome to severe) for any Carolinas Comfort Scale pain-specific questions. Logistic regression analyses were performed to determine statistically significant predictors of chronic pain. Univariate analysis selected potential predictors with a P value less than .15, and a subsequent multivariable model was built using backward elimination setting retention criterion at P < .15. Goodness-of-fit of the model was tested using Hosmer-Lemeshow test. A value of greater than 70% for the area under the curve (AUC) was considered most accurate diagnostically. The final model was then internally validated with bootstrap analysis. RESULTS: A total of 887 patients underwent VHR between 2007 and 2014. The patients had an average age of 57.2 ± 12.8 years, 52.4% were female, 17.0% were active smokers, and 13.2% used narcotics preoperatively. With 74% follow-up at 1 year, 26.0% of the patients reported chronic discomfort. After logistic regression model, independent predictors of pain at 6 months were preoperative pain score 2 or more (P < .0001), preoperative narcotic use (P = .06), and 1-month postoperative pain score 2 or more (P < .0001), AUC = .74. Baseline, 1-month, and 6-month predictors determined the final multivariate regression model for prediction of chronic pain at 1 year, AUC = .73. Older age was protective against chronic pain (odds ratio [OR] .98, 95%confidence interval [CI] = .96 to .998, P = .03), female sex increased risk with an OR of 1.7(CI = 1.1 to 2.7, P = .02); preoperative pain, and recurrent hernia repair nearly doubled the risk of developing chronic pain postoperatively (OR = 3.0, CI = 1.8 to 4.8, P < .0001 and 1.6, CI = .98 to 2.6, P = .06, respectively). Importantly, presence of pain at 1 month was a strong predictor of chronic pain at 1-year follow-up (OR = 2.6, CI = 1.7 to 4.2, P < .0001). CONCLUSIONS: Patients who have preoperative pain and at 1 month postoperatively are significantly more likely to have chronic pain. Both short- and long-term pain can be predicted from female sex, younger age, and repair of recurrent hernias. This predictive model may aid in preoperative counseling and when considering postoperative intervention for pain management in VHR patients.
