RESUMEN
BACKGROUND: Emergent repairs of incarcerated and strangulated ventral hernia repairs (VHR) are associated with higher perioperative morbidity and mortality than those repaired electively. Despite increasing utilization of minimally invasive techniques in elective repairs, the role for laparoscopy in emergent VHR is not well defined, and its feasibility has been demonstrated only in single center studies. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database (2009-2016) was queried for emergent VHR. Laparoscopic and open techniques were compared using univariate and multivariate analyses. RESULTS: A total of 11,075 patients who underwent emergent ventral and incisional hernia repairs were identified: 85.5% open ventral hernia repair (OVHR), 14.5% laparoscopic ventral hernia repair (LVHR). Patients who underwent emergent OVHRs were older, more comorbid, and more likely to be septic at the time of surgery than those undergoing emergent LVHRs. Emergent OVHR patients were more likely to have minor complications (22.1% versus 11.0%; OR 1.7; 95% CI 1.069-2.834). After controlling for confounding variables, LVHR and OVHR had similar outcomes, with the exception of higher rates of superficial surgical site infection in OVHR (5.0% versus 1.8%; odd's ratio (OR) 2.7; 95% confidence interval (CI) 1.176-6.138). Following multivariate analysis, laparoscopic approach demonstrated similar outcomes in major complications, reoperation, and 30-d mortality compared to open repairs. However, when controlling for other confounding factors, LVHR had reduced length of stay compared to OVHR (6.7 versus 4.0 d; 1.6 d longer, standard error 0.77, P < 0.03). CONCLUSIONS: Emergent LVHR is associated with fewer superficial surgical site infection and shorter length of stay than OVHR but no difference in major complications, reoperation or 30-d mortality is associated with LVHR in the emergency setting.

PURPOSE: To compare the effect of home intravenous (IV) versus oral antibiotic therapy on complication rates and resource utilization following appendectomy for perforated appendicitis. METHODS: This was a randomized controlled trial of patients aged 4-17 with surgically treated perforated appendicitis from January 2011 to November 2013. Perforation was defined intraoperatively and divided into three grades: I-contained perforation, II-localized contamination to right gutter/pelvis, and III-diffuse contamination. Patients were randomized to complete a ten-day course of home antibiotic therapy with either IV ertapenem or oral amoxicillin-clavulanate. Thirty-day postoperative complication rates including abscess, readmission, wound infection, and charges were compared. RESULTS: Eighty-two patients were enrolled. Forty four (54%) were randomized to the IV group and 38 (46%) to the oral group. IV patients were older (12.3 ± 3.6 versus 10.1 ± 3.6, p < 0.05) with higher BMI (20.9 ± 5.8 versus 17.9 ± 3.5, p < 0.05). There were no differences in gender, comorbidities, or perforation grade (I-20.4% vs. 26.3%, II-36.4% vs. 34.2%, III-43.2% vs. 39.5%, all p > 0.05). Comparing IV to oral, there was no difference in length of stay (4.4 ± 1.5 versus 4.4 ± 2.0 days, p > 0.05), postoperative abscess rate (11.6% vs. 8.1%, p > 0.05), or readmission rate (14.0% vs. 16.2%, p > 0.05). Hospital and outpatient charges were higher in the IV group (p < 0.0001). CONCLUSION: Oral antibiotics had equivalent outcomes and incurred fewer charges than IV antibiotics following appendectomy for perforated appendicitis.

BACKGROUND: Optimal management following index laparotomy is poorly defined in secondary peritonitis patients. Although "open abdomen" (OA), or temporary abdominal closure with planned relaparotomy, is used to reassess bowel viability or severity of contamination, recent studies demonstrate comparable morbidity and mortality with primary abdominal closure (PC). This study evaluates differences between OA and PC following emergent laparotomy. METHODS: Using the Premier database at a quaternary care center (2012-2016), nontrauma patients with secondary peritonitis requiring emergent laparotomy were identified (N = 534). Propensity matching for PC (n = 331; 62%) or OA (n = 203; 38%) was performed using variables: Mannheim Peritonitis Index, lactate, and vasopressor requirement. One hundred eleven closely matched pairs (PC:OA) were compared. RESULTS: Five hundred thirty-four patients (55.0% female; mean age, 59.6 ± 15.5 years) underwent emergent laparotomy. Of the OA patients, 136 (67.0%) had one relaparotomy, while 67 (33.0%) underwent multiple reoperations. Compared to daytime cases, laparotomies performed overnight (6 pm-6 am) had more temporary closures with OA (42.8% OA vs. 57.2% PC, p = 0.04). When assessing by surgeon type, PC was performed in 78.7% of laparotomies by surgical subspecialties compared to 56.7% (p < 0.0001) of acute care surgeons. After propensity matching, OA patients had increased postoperative complications (71.2% vs. 41.4%, p < 0.0001), mortality (22.5% vs. 11.7%, p = 0.006), and longer median length of stay (13 vs. 9 days, p = 0.0001). CONCLUSION: Open abdomen was performed in 38.0% of patients, with one-third of those requiring multiple reoperations. Complications, mortality rates, and costs associated with OA were significantly increased when compared to PC. Given these findings, future studies are needed to determine appropriate indications for OA. LEVEL OF EVIDENCE: Therapeutic/care management, level IV.

BACKGROUND: Mesh choice in open ventral hernia repair (OVHR) remains controversial. Our aim was to analyze prospective outcomes among heavyweight, midweight, and lightweight (LW) mesh. METHODS: A study of the International Hernia Mesh Registry was performed for OVHR. Operative details, complications, recurrence, and quality of life (QOL) at 1, 6, 12, 24, and 36 months were evaluated. RESULTS: There were 549 OVHRs, 99 using heavyweight, 262 midweight, and 188 LW mesh. Heavyweight group had larger defects (P ≤ .008). Midweight patients had fewer superficial surgical site infections (P = .04) and shorter LOS (P < .0001). Recurrence rates were equal (6.1% vs 6.1% vs 8.0%; P = .71). After controlling for surgical location, component separation, and preoperative pain with multivariate analysis, LW mesh was associated with an overall worse QOL at 6 months and pain at 1 year. CONCLUSIONS: MW mesh had fewer superficial surgical site infections and shorter LOS. After controlling for potential confounding variables, LW mesh had a worse QOL at 6 and 12 months.

BACKGROUND: Complications of bariatric surgeries are common, can occur throughout the patient's lifetime, and can be life-threatening. We examined bariatric surgical complications presenting to our acute care surgery service. METHODS: Records were reviewed from January 2007 to June 2013 for patients presenting with a complication after bariatric surgery. RESULTS: Laparoscopic Roux-en-Y gastric bypass was the most common index operation (n = 20), followed by open Roux-en-Y gastric bypass (n = 6), laparoscopic gastric band (n = 4), and vertical banded gastroplasty (n = 3). Diagnoses included internal hernia (n = 10), small bowel obstruction (n = 5), lap band restriction (n = 4), biliary disease (n = 3), upper GI bleeding or ulcer (n = 3), ischemic bowel (n = 2), marginal ulcer (n = 2), gastric outlet obstruction (n = 2), perforated ulcer (n = 2), intussusception (n = 1), and incarcerated ventral hernia (n = 1). Operations were required in 91% of the patients. Laparoscopic outcomes were similar to open; however, open cases were more emergent (23.5% vs 69.2%) and had longer hospital length of stay (4.8 ± 3.5 vs 11.0 ± 10.3 days, P < .05). All patients survived. CONCLUSIONS: The acute care surgeon will encounter complications of bariatric surgery. Internal hernias or obstructive etiologies are the most common presentations and often require emergent or urgent surgery.

AIM: To characterize differences of arterial (ABG) and venous (VBG) blood gas analysis in a rabbit model of hemorrhagic shock. METHODS: Following baseline arterial and venous blood gas analysis, fifty anesthetized, ventilated New Zealand white rabbits were hemorrhaged to and maintained at a mean arterial pressure of 40 mmHg until a state of shock was obtained, as defined by arterial pH ≤ 7.2 and base deficit ≤ -15 mmol/L. Simultaneous ABG and VBG were obtained at 3 minute intervals. Comparisons of pH, base deficit, pCO2, and arteriovenous (a-v) differences were then made between ABG and VBG at baseline and shock states. Statistical analysis was applied where appropriate with a significance of P < 0.05. RESULTS: All 50 animals were hemorrhaged to shock status and euthanized; no unexpected loss occurred. Significant differences were noted between baseline and shock states in blood gases for the following parameters: pH was significantly decreased in both arterial (7.39 ± 0.12 to 7.14 ± 0.18) and venous blood gases (7.35 ± 0.15 to 6.98 ± 0.26, P < 0.05), base deficit was significantly increased for arterial (-0.9 ± 3.9 mEq/L vs -17.8 ± 2.2 mEq/L) and venous blood gasses (-0.8 ± 3.8 mEq/L vs -15.3 ± 4.1 mEq/L, P < 0.05). pCO2 trends (baseline to shock) demonstrated a decrease in arterial blood (40.0 ± 9.1 mmHg vs 28.9 ± 7.1 mmHg) but an increase in venous blood (46.0 ± 10.1 mmHg vs 62.8 ± 15.3 mmHg), although these trends were non-significant. For calculated arteriovenous differences between baseline and shock states, only the pCO2 difference was shown to be significant during shock. CONCLUSION: In this rabbit model, significant differences exist in blood gas measurements for arterial and venous blood after hemorrhagic shock. A widened pCO2 a-v difference during hemorrhage, reflective of poor tissue oxygenation, may be a better indicator of impending shock.
