Are we doing too many non-therapeutic laparotomies in trauma? An analysis of the National Trauma Data Bank.

BACKGROUND: Exploratory laparotomy (EL) has been the definitive diagnostic and therapeutic modality for operative abdominal trauma in the US. Recently, many trauma centers have started using diagnostic laparoscopy (DL) in stable trauma patients in an effort to reduce the incidence of non-therapeutic laparotomy (NL). We aim to evaluate the incidence of NL in the trauma population in the US and compare the outcomes between DL and NL. METHODS: Using ICD-9 codes, the National Trauma Data Bank (2010-2015) was queried for patients undergoing any abdominal surgical intervention. Patients were divided into two groups: diagnostic laparoscopy (DL) and exploratory laparotomy (EL). Hemodynamically unstable patients on arrival and patients with abbreviated injury score (AIS) > 3 were excluded. Patients in EL group without any codes for gastrointestinal, diaphragmatic, hepatic, splenic, vascular, or urological procedures were considered to have undergone NL. After excluding patients who were converted to open from the DL group, multivariate regression models were used to analyze the outcomes of DL vs NL group with respect to mortality, length of stay, and complications. RESULTS: A total of 3197 patients underwent NL vs 1323 patients who underwent DL. Compared to DL group, the NL group were older (mean age: 35 vs. 31, P < 0.01). Rate of penetrating injury was 77% vs 86% for patients in NL vs DL. On multivariate analysis, NL was associated with increased mortality (OR 4.5, 95% CI 2.1-9.7), higher rate of complications (OR 2.2, 95% CI 1.4-3.3), and a longer hospital stay (OR 2.7, 95% CI 2.1-3.5). NL was also associated with higher rates of pneumonia, VTE, ARDS, and cardiac arrest. CONCLUSION: With increasing experience in minimally invasive surgery, DL should be a part of the armamentarium of trauma surgeons. This study supports that in well-selected trauma patients DL has favorable outcomes compared to NL. These findings warrant further investigation.

Percutaneous Gastrostomy Device for the Treatment of Class II and Class III Obesity: Results of a Randomized Controlled Trial.

OBJECTIVES: The AspireAssist System (AspireAssist) is an endoscopic weight loss device that is comprised of an endoscopically placed percutaneous gastrostomy tube and an external device to facilitate drainage of about 30% of the calories consumed in a meal, in conjunction with lifestyle (diet and exercise) counseling. METHODS: In this 52-week clinical trial, 207 participants with a body-mass index (BMI) of 35.0-55.0 kg/m2 were randomly assigned in a 2:1 ratio to treatment with AspireAssist plus Lifestyle Counseling (n=137; mean BMI was 42.2±5.1 kg/m2) or Lifestyle Counseling alone (n=70; mean BMI was 40.9±3.9 kg/m2). The co-primary end points were mean percent excess weight loss and the proportion of participants who achieved at least a 25% excess weight loss. RESULTS: At 52 weeks, participants in the AspireAssist group, on a modified intent-to-treat basis, had lost a mean (±s.d.) of 31.5±26.7% of their excess body weight (12.1±9.6% total body weight), whereas those in the Lifestyle Counseling group had lost a mean of 9.8±15.5% of their excess body weight (3.5±6.0% total body weight) (P<0.001). A total of 58.6% of participants in the AspireAssist group and 15.3% of participants in the Lifestyle Counseling group lost at least 25% of their excess body weight (P<0.001). The most frequently reported adverse events were abdominal pain and discomfort in the perioperative period and peristomal granulation tissue and peristomal irritation in the postoperative period. Serious adverse events were reported in 3.6% of participants in the AspireAssist group. CONCLUSIONS: The AspireAssist System was associated with greater weight loss than Lifestyle Counseling alone.

The relationship between neighborhood socioeconomic status and short-term outcomes following colon resection.

BACKGROUND: This study investigates the association between neighborhood socioeconomic status, measured by the Distressed Communities Index (DCI), and short-term outcomes following colon resection. METHODS: Utilizing the Maryland State Inpatient Sample database (SID 2018-2020), we determined the association between DCI and post-op outcomes following colon resection including length of stay, readmissions, 30-day in-hospital mortality, and non-routine discharges. Multivariate regression analysis was performed to control for potential confounding factors. RESULTS: Of the 13,839 patients studied, median age was 63, with 54.3 â€‹% female and 64.5 â€‹% elective admissions. Laparoscopic surgery was performed in 36.9 â€‹% cases, with a median hospital stay of 5 days. Patients in distressed communities faced higher risks of emergency admission (OR: 1.31), prolonged hospitalization (OR: 1.29), non-routine discharges (OR: 1.36), and readmission (OR: 1.33). Black patients had longer stays than White patients (OR: 1.3). Despite adjustments, in-hospital mortality did not significantly differ among neighborhoods. CONCLUSION: Our study reveals that patients residing in distressed neighborhoods face a higher risk of prolonged hospitalization, non-routine discharges, and readmission rate after colon resection.

The impact of the affordable care act on access to bariatric surgery in Maryland.

INTRODUCTION: This study aims to investigate the influence of the Affordable Care Act (ACA) on the utilization of Roux-en-Y gastric bypass (RYGB) procedures in Maryland. METHODS: Using the Maryland State Inpatient Database, this retrospective study compared all patients undergoing RYGB during the pre-ACA (2007-2009) and post-ACA (2018-2020) periods, including patient demographic factors, pre-existing conditions, and socioeconomic factors. RESULTS: A total of 16,494 RYGB procedures were performed during the study period, of which 12,089 (73.3 â€‹%) were post-ACA. This was a 179.2 â€‹% increase in patients undergoing RYGB post-ACA; nearly triple that of the pre-ACA period. There was a significant decrease in uninsured patients (5.6 â€‹%-1.5 â€‹%, p â€‹< â€‹0.01) an increase in Black patients (32.1 â€‹%-46.8 â€‹%, p â€‹< â€‹0.01) and Medicaid beneficiaries (6.0 â€‹% pre-ACA to 17.8 â€‹% post-ACA, p â€‹< â€‹0.01). There were significant reductions in adverse outcomes (long hospital stays, hemorrhage, GIT leaks, and mortality) across all insurance types (all p â€‹< â€‹0.01). CONCLUSION: The ACA increased access to RYGB procedures, especially in Black and Medicaid recipients in Maryland, enhancing healthcare across all insurance types.

Race, Insurance, and Socioeconomic Influences on Outcomes Following Roux-En-Y Gastric Bypass.

The effectiveness of Roux-en-Y gastric bypass (RYGB) might be shadowed by disparities in outcomes related to patient race and insurance type. We determine the influence of patient race/ethnicity and insurance types on complications following RYGB. We performed a retrospective analysis using data sourced from the National Inpatient Sample Database (2010 to 2019). A multivariate analysis was employed to determine the relationship between patient race/ethnicity and insurance type on RYGB complications. The analysis determined the interaction between race/ethnicity and insurance type on RYGB outcomes. We analyzed 277714 patients who underwent RYGB. Most of these patients were White (64.5%) and female (77.3%), with a median age of 46 years (IQR 36-55). Medicaid beneficiaries displayed less favorable outcomes than those under private insurance: Extended hospital stay (OR = 1.68; 95% CI 1.58-1.78), GIT Leak (OR = 1.83; 95% CI 1.35-2.47), postoperative wound infection (OR = 1.88; 95% CI 1.38-2.55), and in-hospital mortality (OR = 2.74; 95% CI 1.90-3.95).

Utilization and Outcomes of Roux-en-Y Gastric Bypass Surgery Following the Affordable Care Act in the United States.

BACKGROUND: The passage of the Affordable Care Act (ACA) in 2010 marked a pivotal moment in American health care policy, significantly expanding access to health care services. This study aims to explore the relationship between the ACA and the utilization and outcomes of Roux-en-Y Gastric Bypass (RYGB) surgery. METHODS: Using data from the National Inpatient Sample (NIS) Database, this retrospective study compares the pre-ACA period (2007-2009) with the post-ACA period (2017-2019), encompassing patients who had RYGB. Multivariable logistic analysis was done accounting for patient's characteristics, comorbidities, and hospital type. RESULTS: In the combined periods, there were 158 186 RYGB procedures performed, with 30.0% transpiring in pre-ACA and 70.0% in the post-ACA. Post-ACA, the proportion of uninsured patients decreased from 4.8% to 3.6% (P < .05), while Black patients increased from 12.5% to 18.5% (P < .05). Medicaid-insured patients increased from 6.8% to 18.1% (P < .05), and patients in the poorest income quartile increased from 20% to 26% (P < .05). Patients in the post-ACA period were less likely to have longer hospital stays (OR = .16: 95% CI .16-.17, P < .01), in-hospital mortality (OR = .29: 95% CI .18-.46, P < .01), surgical site infection (OR = .25: 95% CI .21-.29, P < .01), postop hemorrhage (OR = .24: 95% CI .21-.28, P < .01), and anastomotic leak (OR = .14: 95% CI .10-.18, P < .01) than those in the pre-ACA period. DISCUSSION: Following the implementation of the ACA, utilization of bariatric surgery significantly increased, especially among Black patients, Medicaid beneficiaries, and low-income patients. Moreover, despite the inclusion of more high-risk surgical patients in the post-ACA period, there were better outcomes after surgery.

Early Cholecystectomy in Patients with Sickle Cell Disease with Uncomplicated Cholelithiasis Is Associated with Better Outcomes.

BACKGROUND: Up to 85% of patients with sickle cell disease (SCD) will develop gallstones by their third decade. Cholecystectomy is the most commonly performed procedure in these patients. Cholecystectomy is recommended for patients with SCD with symptomatic cholelithiasis and leads to lower morbidity. No contemporary large studies have evaluated this recommendation or associated clinical outcomes. This study evaluates clinical outcomes after cholecystectomy in patients with SCD and cholelithiasis with specific advanced clinical presentations. STUDY DESIGN: The Nationwide Inpatient Sample was queried for patients with SCD and gallbladder disease between 2006 and 2015. Patients were divided into groups based on their disease presentation, including uncomplicated cholelithiasis, acute and chronic cholecystitis, and gallstone pancreatitis. Clinical outcomes associated with disease presentation were analyzed. Statistical analysis was performed using the Student's t -test, chi-square test, ANOVA, and logistic regression. RESULTS: There were 6,662 patients with SCD who presented with cholelithiasis. Median age was 20 (interquartile range 16 to 34) years and 54% were female patients. Cholecystectomy was performed in 1,779 patients with SCD with the most common indication being chronic cholecystitis (44%), followed by uncomplicated cholelithiasis (27%), acute cholecystitis (21%), and choledocholithiasis or gallstone pancreatitis (8%). On multivariable regression, advanced clinical presentation was the strongest predictor of perioperative vaso-occlusive crisis, which was the most common complication. Patients undergoing cholecystectomy for uncomplicated cholelithiasis were at lower risk than those with acute cholecystitis (odds ratio [OR] 2.37; 95% CI 1.64 to 3.41), chronic cholecystitis (OR 1.74; 95% CI 1.26 to 2.4), and choledocholithiasis or gallstone pancreatitis (OR 2.24; 95% CI 1.41 to 3.57). CONCLUSIONS: Seventy-three percent of patients with SCD have advanced clinical presentation at the time of their cholecystectomy. After cholecystectomy, perioperative vaso-occlusive events were significantly increased in patients with advanced clinical presentation. These data support screening abdominal ultrasounds and early cholecystectomy for cholelithiasis in patients with SCD.

Surgical management of esophageal diverticulum: a review of the Nationwide Inpatient Sample database.

BACKGROUND: Esophageal diverticulum is rare in the United States. The mainstay treatment of symptomatic esophageal diverticulum is surgical correction. Much of the available information regarding esophageal diverticulum and its surgical management has been derived from small studies and institutional reviews. Our study objective was to investigate the demographics, perioperative conditions, and predictors of outcomes after surgical treatment of acquired esophageal diverticulum using a nationally representative database. METHODS: A retrospective review using the Nationwide Inpatient Sample database from 2000-2009 was performed for patients with acquired esophageal diverticulum. The patients were stratified into Zenker's diverticulum (ZD) or non-Zenker's diverticulum (NZD) subgroups. The covariates retrieved included age, gender, ethnicity, insurance type, and Charlson comorbidity index. A multivariate analysis was performed to determine the predictors of postoperative morbidity. Discharge-level weights were applied. RESULTS: Overall, a total of 4253 patients met our inclusion criteria, 3197 (75%) with ZD and 1056 (25%) with NZD. In the ZD group, the mean age was 73 ± 12.3 y, and most were men (55%) and white (67%). The mean length of stay was 5.82 ± 8.08 d, and the mortality rate was 1.2%. The most common complication was septicemia or sepsis (2.0%). The black patients had higher odds of postoperative morbidity than the white patients (odds ratio [OR] 2.29, 95% confidence interval [CI] 1.02-5.17). The risk of overall postoperative morbidity was 52% greater for women (OR 1.52, 95% CI 1.01-2.29). An increasing Charlson comorbidity index was an independent predictor of morbidity. In the NZD group, the mean age was 69 ± 13.9 y, and most were also men (51%) and white (63%). The mean length of stay was 8.13 ± 10.56 d, and the mortality rate was 1.6%. The most common complication was air leak (3.1%). The black and Hispanic patients had higher odds of postoperative morbidity than the white patients (OR 1.97, 95% CI 1.05-3.72 and OR 2.37, 95% CI 1.06-5.30, respectively). An increasing Charlson comorbidity index was an independent predictor of morbidity. Compared with laparoscopy, the risk of developing postoperative morbidity was higher with the thoracotomy procedure (OR 7.45, 95% CI 1.11-50.18). CONCLUSIONS: Using a nationally representative database, our study found that female gender, black race, and the presence of comorbidities were associated with increased postoperative morbidity among patients with ZD. Among the patients with NZD, black and Hispanic patients had worse postoperative morbidity than the white patients, and the presence of comorbidities was associated with increased postoperative morbidity. Thoracotomy for the correction of NZD was associated with increased postoperative morbidity compared with the laparoscopic approach.

Open reduction internal fixation versus hemiarthroplasty versus total hip arthroplasty in the elderly: a review of the National Surgical Quality Improvement Program database.

BACKGROUND: Total hip arthroplasty (THA), hemiarthroplasty (HA), and open reduction internal fixation (ORIF) are treatment options for femoral neck fractures. However, the optimal surgical treatment remains unclear. The present study aimed to describe the 30-d postoperative outcomes of THA, HA, and ORIF among patients aged ≥65 y with femoral neck fractures within a national surgical database. MATERIALS AND METHODS: A retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program for January 2005 through December 2009 was conducted. We included patients aged ≥65 y who had undergone THA, HA, or ORIF for femoral neck fractures. We collected information on patient demographics, comorbidities, risk factors, and complication rates. A logistic regression model was used to assess the variation in overall morbidity and mortality after surgery. RESULTS: Overall, 3423 patients met the inclusion criteria: 674 underwent ORIF, 428 HA, and 2321 THA. Most patients were white (83.6%, n = 2862), female (64.4%, n = 2204), and >70 y old (78.4%, n = 2682). On adjusted multivariate analysis, no differences were found in the 30-d mortality rates among the ORIF, HA, and THA groups. Patients who underwent ORIF (odds ratio 0.51, 95% confidence interval 0.27-0.94) and HA (odds ratio 0.43, 95% confidence interval 0.22-0.84) had a lower likelihood of developing respiratory complications compared with those who underwent THA. CONCLUSIONS: No differences were found in the 30-d mortality rates among the ORIF, HA, and THA groups. ORIF and HA resulted in a lower likelihood of developing respiratory complications than THA.

Open versus laparoscopic hiatal hernia repair.

BACKGROUND: The literature reports the efficacy of the laparoscopic approach to paraesophageal hiatal hernia repair. However, its adoption as the preferred surgical approach and the risks associated with paraesophageal hiatal hernia repair have not been reviewed in a large database. METHOD: The Nationwide Inpatient Sample dataset was queried from 1998 to 2005 for patients who underwent repair of a complicated (the entire stomach moves into the chest cavity) versus uncomplicated (only the upper part of the stomach protrudes into the chest) paraesophageal hiatal hernia via the laparoscopic, open abdominal, or open thoracic approach. A multivariate analysis was performed controlling for demographics and comorbidities while looking for independent risk factors for mortality. RESULTS: In total, 23,514 patients met the inclusion criteria. By surgical approach, 55% of patients underwent open abdominal, 35% laparoscopic, and 10% open thoracic repairs. Length of stay was significantly reduced for all patients after laparoscopic repair (P < .001). Age ≥60 years and nonwhite ethnicity were associated with significantly higher odds of death. Laparoscopic repair and obesity were associated with lower odds of death in the uncomplicated group. CONCLUSION: Laparoscopic repair of paraesophageal hiatal hernia is associated with a lower mortality in the uncomplicated group. However, older age and Hispanic ethnicity increased the odds of death.

Predictors of marginal ulcers after laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a highly effective therapy for morbid obesity. As the most common postoperative complication, marginal ulcers (MU) present a significant disease burden. The etiology of marginal ulcers after gastric bypass has not been clearly defined. The purpose of this study was to identify independent risk factors for MU. METHODS: We performed a retrospective study of a single surgeon's experience performing LRYGB between July 2001 and January 2006 in a United States private practice and university hospital. We investigated patient factors and comorbidities associated with the development of marginal ulcers. The five most common comorbidities were hypertension, type 2 diabetes mellitus, gastroesophageal reflux disease, hyperlipidemia, and obstructive sleep apnea. We analyzed these factors using multivariate logistic regression adjusting for demographics, BMI, and all comorbidities. RESULTS: In our 763 patients, 89% were female, 84.7% were African-American, and the mean BMI was 50.2 kg/m(2) before surgery. Marginal ulcers occurred in 23 patients (3.01%) over a mean of 64 months. On χ(2) analysis, hypertension, gastroesophageal reflux disease, hyperlipidemia, and sleep apnea were significantly correlated with MU. On multivariate analysis, the odds of marginal ulcer formation were 7.84 among hypertensive patients with a 95% confidence interval of 1.75-35.06 (P = 0.007). Hypertension was the only significant predictor of marginal ulcer disease. CONCLUSION: In our study, marginal ulcers occurred more frequently in patients with preoperative hypertension. At higher risk, these patients could be good candidates for extended acid suppression prophylaxis after LRYGB.

Does BMI affect perioperative complications following total knee and hip arthroplasty?

BACKGROUND: Orthopedic surgeons are reluctant to perform total knee (TKA) or hip (THA) arthroplasty on patients with high body mass index (BMI). Recent studies are conflicting regarding the risk of obesity on perioperative complications. Our study investigates the effect of BMI on perioperative complications in patients undergoing TKA and THA using a national risk-adjusted database. METHODS: A retrospective analysis was performed using the 2005-2007 American College of Surgeons-National Surgical Quality Improvement Program ACS-NSQIP dataset. Inclusion criteria were patients between 18 and 90 y of age who underwent TKA or THA. Patients were stratified into five BMI categories: normal, overweight, obese class I, obese class II, and morbidly obese. Demographic characteristics, length of stay, co-morbidities, and complication rates were compared across the BMI categories. RESULTS: A total of 1731 patients met the inclusion criteria, with 66% and 34% undergoing TKA and THA, respectively. A majority were female (60%) and >60 y (70%) in age. Of the patients who underwent TKA, 90% were either overweight or obese, compared with 77% in those undergoing THA. The overall preoperative comorbidity rate was 73%. The complication and mortality rates were 7% and 0.4%, respectively. When stratifying perioperative complications by BMI categories, no differences existed in the rates of infection (P = 0.368), respiratory (P = 0.073), cardiac (P = 0.381), renal (P = 0.558), and systemic (P = 0.216) complications. CONCLUSIONS: Our study demonstrates no statistical difference in perioperative complication rates in patients undergoing TKA or THA across BMI categories. Performing TKA or THA on patients with high BMI may increase mobility leading to improved quality of life.

Laparoscopic appendectomy in children with complicated appendicitis: ethnic disparity amid changing trend.

BACKGROUND: Laparoscopic appendectomy (LA) has gained acceptance in the treatment of uncomplicated appendicitis in the pediatric population. The role of LA versus open appendectomy (OA) in complicated (perforated) appendicitis has remained controversial. METHODS: A 10-y review of the Nationwide Inpatient Sample (HCUP-NIS) and 3 y of non-overlapping data from the Kids' Inpatient Database (KID) (2000, 2003, and 2006) was performed on pediatric patients (age <18 y) with complicated appendicitis. Patients were classified based on gender, race, insurance status, and type of appendectomy performed. Multivariate regression was conducted adjusting for age, race, gender, and type of appendectomy, with mortality and length of hospital stay (LOS) as outcomes. RESULTS: An estimated 72,787 patients met the inclusion criteria with a median age of 11 y. The majorities of the patients were male (59.9%), Caucasian (38.1%), and insured (89.7%). Twenty-nine percent underwent LA while 71% had OA. Proportion of LA increased from 9.9% in 1999 to 46.6% in 2007. On multivariate analysis, African-Americans were less likely to undergo LA compared with Caucasians (OR: 0.80, CI = 0.69-0.92, P = 0.002) despite an increased odds of undergoing LA over the last decade from 1998 to 2007 in the entire study population (OR 6.27, 95% CI 4.73-8.30, P = 0.000). Increasing age and gender were also associated with likelihood of receiving LA (OR: 1.08, CI = 1.06-1.10 and OR 1.25, 95% CI 1.18-1.31, P < 0.001). CONCLUSIONS: LA is gradually gaining acceptance over the years as an alternative to OA for complicated appendicitis, However, minority difference still exists in choice of procedure. There is a need to further investigate this disparity as it may be related to access to skilled laparoscopic pediatric surgeons.

Gastric prolapse with pseudocysts following laparoscopic adjustable gastric banding.

INTRODUCTION: Laparoscopic adjustable gastric banding (LAGB) is a reversible method of surgical gastric restriction. Following LAGB, the adverse event most commonly necessitating subsequent reoperation is prolapse of the gastric corpus or fundus above the band. A review of the medical literature reveals no reports of nonpancreatic pseudocysts being associated with this adverse event. Nonpancreatic pseudocysts, encountered during revisional bariatric surgery should be considered a cause of irreducible gastric prolapse. CASE REPORT: We report the case of a 41-year-old Caucasian female who underwent laparoscopic surgery to revise an adjustable gastric band and to repair an anterior gastric prolapse. Intraoperatively, 2 pseudocysts were found on the gastric fundus above the band in association with the gastric prolapse. The pseudocysts were resected, the gastric prolapse was reduced, and the band was left in place. The patient recovered uneventfully. CONCLUSION: Nonpancreatic pseudocysts may be associated with gastric prolapse in patients who have undergone LAGB. These pseudocysts can often be excised laparoscopically without violating the gastric lumen. This atypical presentation of gastric prolapse may pose a diagnostic and therapeutic challenge as these patients may.

Should I be Concerned? Surgical Training in the Time of COVID19.

As the US healthcare system restructured to deal with the COVID-19 pandemic, medical training was significantly disrupted. During the peak of the crisis, three surgical trainees in different stages of their residency shared their experiences and concerns on how this pandemic affected their training. The article is intended to generate discussion on the concerns of derailment and stagnation of surgical training and difficulties faced at all levels of surgical training to perform clinical duties and fulfill academic responsibilities during the early months of the COVID pandemic.

Characteristics and resolution of hypertension in obese African American bariatric cohort.

Weight reduction continues to be first-line therapy in the treatment of hypertension (HTN). However, the long-term effect of bariatric malabsorptive surgical techniques such as Roux-en-Y Gastric Bypass (RYGB) surgery in the management of hypertension (HTN) is less clear. African Americans (AA) are disproportionately affected by obesity and hypertension and have inconsistent outcomes after bariatric surgery (BS). Despite a plethora of bariatric literature, data about characteristics of a predominantly AA bariatric hypertensive cohort including hypertension in obese (HIO) are scarce and underreported. The aims of this study were, (1) to describe the preoperative clinical characteristics of HIO with respect to HTN status and age, and (2) to identify predictors of HTN resolution one year after RYGB surgery in an AA bariatric cohort enrolled at the Howard University Center for Wellness and Weight Loss Surgery (HUCWWS). In the review of 169 AA bariatric patients, the average BMI was 48.50 kg/m2 and the average age was 43.86 years. Obese hypertensive patients were older (46 years vs. 37.89 years; p < .0001); had higher prevalence of diabetes mellitus (DM, 43.09% vs. 10.87%; p < .0001) and dyslipidemia (38.2% vs. 13.04%; p 0.002). Hypertensive AA who were taking ≥ 2 antihypertensive medications prior to RYGB were 18 times less likely to experience HTN resolution compared to hypertensive AA taking 0-1 medications, who showed full or partial response. Also, HIO was less likely to resolve after RYGB surgery in patients who needed ≥ 2 antihypertensive medications prior to surgical intervention.

Laparoscopic versus open appendectomy in complicated appendicitis: a review of the NSQIP database.

BACKGROUND: Laparoscopic appendectomy (LA) has been an established treatment method for uncomplicated acute appendicitis. Controversy still exits regarding the superiority of either laparoscopic or open technique for the treatment of complicated appendicitis. OBJECTIVE: To examine for benefits in postoperative morbidity comparing laparoscopic versus open appendectomy for complicated appendicitis. METHODS: A retrospective analysis was performed using the American College of Surgeon's National Surgical Quality Improvement Project (ACS-NSQIP) dataset between 2005 and 2007. Inclusion criteria were patients undergoing either open or laparoscopic appendectomy, and had complicated appendicitis. Patients with negative appendectomies and age less than 18 y old were excluded. The primary outcome variable was postoperative complications. Multivariate analysis was performed adjusting for demographics and standard NSQIP comorbidities. RESULTS: We identified 2,790 complicated appendicitis cases treated with laparoscopic or open appendectomy. The majority were male (56.6%), White (70.3%), and 39.1% were younger than 40 y of age. On unadjusted analyses, the mean length of stay was significantly shorter for LA cases (3.97 d) than OA cases (5.13 d) (P < 0.001). On multivariate analysis, superficial surgical site infection was 70% less likely to occur in LA (OR 0.304 P = 0.000), organ space infection was 2-fold more likely to occur in LA (OR 2.19 P = 0.003), and dehiscence was 78% less likely to occur in LA (OR 0.22 P = 0.015). CONCLUSION: In cases of complicated appendicitis, laparoscopic appendectomy is superior in terms of superficial and deep wound infections; however, it is associated with an increased incidence of postoperative intra-abdominal abscess.

Comparison of the clinical and economic outcomes between open and minimally invasive appendectomy and colectomy: evidence from a large commercial payer database.

BACKGROUND: Appendectomy and colectomy are commonly performed surgical procedures. Despite evidence demonstrating advantages with the minimally invasive surgical (MIS) approach, open procedures occur with greater prevalence. Therefore, there is still controversy as to whether the MIS approach is safer or more cost effective. METHODS: A retrospective analysis was performed using a large commercial payer database. The data included information on 7,532 appendectomies and 2,745 colectomies. Data on the distribution of patient demographic and comorbidity characteristics associated with the MIS and open approaches were reviewed. The corresponding complication rates and expenditures were analyzed. Summary statistics were compared using chi-square tests, and generalized linear models were constructed to estimate expenditures while controlling for patient characteristics. RESULTS: The patients undergoing MIS and open colectomy showed no significant variations in age distribution or marginal age differences for appendectomy. Significantly more patients experienced an infection postoperatively, and procedure-specific complications were more common in the open group for both procedures (P\0.05). The postsurgical hospital stay was longer for the patients treated using the open techniques, differing an average of half a day for appendectomies and significantly more (4 days) for colectomy (P\0.05). Readmission rates differed little between the two approaches. Procedures performed through an MIS approach were associated with lower expenditures than for the open technique, with differences ranging from $700 for appendectomy patients (P\0.05) to $15,200 for colectomy patients (P\0.05). CONCLUSIONS: Minimally invasive appendectomy and colectomy were associated with lower infection rates, fewer complications, shorter hospital stays, and lower expenditures than open surgery.

Decreasing anastomotic and staple line leaks after laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: Anastomotic and staple line leaks (ASL) occur after laparoscopic Roux-en-Y gastric bypass (LRYGB) with a reported incidence as high as 6%. Leaks are the second most common cause of post-LRYGB mortality after pulmonary embolism, and can be associated with significant morbidity. Prevention and early detection may limit both morbidity and mortality. METHODS: A retrospective analysis of prospectively collected data was performed on all LRYGBs performed in a community hospital by a single surgeon from August 2001 to December 2005. All operations were performed using a linear-stapled anastomosis with buttressing material, handsewn otomy closures, stay sutures, intraoperative leak testing, and fibrin sealant. RESULTS: 760 patients underwent LRYGB during the study period. Eighty-nine percent (n = 674) were female and 11% (n = 86) were male. Mean body mass index (BMI) was 50 kg/m2 (range 36-83 kg/m2). Mean age was 40 years (range 17-72 years). Two patients developed three gastric pouch staple line leaks (0.4%). There were no mortalities. CONCLUSION: Operative technique, including appropriate staple sizing, staple line reinforcement, handsewn otomy closures, placement of stay sutures, intraoperative leak testing, and placement of fibrin sealant contributed to a lower than expected incidence of ASL after LRYGB in this series.

Guillain-Barré syndrome and postbariatric surgery polyneuropathies.

BACKGROUND: Postbariatric surgery poly-neuropathies (BSP) are infrequent events. However, with the number of gastric bypasses performed each year increasing, the incidence of BSP is expected to increase as well. The long-term sequelae of BSP worsen with delays in diagnoses. Therefore, early evaluation, recognition, and treatment are important in minimizing morbidity and mortality. METHODS: We present the case report of a patient who developed a poly-neuropathy after a laparoscopic Roux-en-Y gastric bypass. RESULTS: The patient's symptoms were ultimately determined to result from Guillain-Barré syndrome. Symptoms resolved with proper treatment. CONCLUSION: Characteristic differences exist between the various surgery poly-neuropathies. With proper evaluation, this determination will aid in prompt and appropriate treatment and will prevent morbidity and mortality.
