The Minimally Invasive Inguinal Hernia: Current Trends and Considerations.

Inguinal hernias are one of the most common surgical pathologies faced by the general surgeon in modern medicine. The cumulative incidence of an inguinal hernia is around 25% in men and 3% in women. The majority of inguinal hernias can be repaired minimally invasively, utilizing either robotic or laparoscopic approaches.

The impact of frailty on outcomes following laparoscopic repair of 'giant' paraesophageal hernias.

BACKGROUND: Frailty is a measure of physiologic reserve and correlates with surgical outcomes in the elderly. Patients who present with giant paraesophageal hernias (PEH) are typically older than 65. We defined 'giant' as a PEH with 50% or more of the stomach in the chest. We hypothesized that frailty correlates with 30-day complications, length of stay, and discharge destination following laparoscopic giant PEH repair. METHODS: Patients older than 65 to undergo primary laparoscopic repair of a giant PEH at a single academic medical center between 2015 and 2022 were included. Hernia size was determined by preoperative imaging. Frailty was assessed clinically prior to surgery using the modified Frailty Index (mFI), an 11-item instrument that counts clinical deficits associated with frailty. A score ≥ 3 was considered frail. A major complication was a Clavien grade IIIB or higher. RESULTS: Of the 162 patients included in the study, mean age was 74.4 ± 7.2, and 66% of patients were female (n = 128). The mFI was ≥ 3 in 37 patients (22.8%). Frail patients were older (78 ± 7.9 vs. 73 ± 6.6 years, p = 0.02). There was no difference in overall complication rate (40.5% vs. 29.6%, p = 0.22) or major complication rate (8.1% vs. 4.8%, p = 0.20) between frail and non-frail patients. Functionally impaired patients (METS < 4) were more likely to develop a major complication (17.9% vs. 3.0%, p < 0.01). Average length of stay was 2.4 days, and frail patients experienced a longer mean hospital stay (2.5 ± 0.2 vs. 2.3 ± 1.8, p = 0.03). Frail patients were more likely to be discharged to a destination other than home. CONCLUSION: Increased frailty as assessed by the mFI is correlated with length of stay and discharge destination following laparoscopic repair of giant PEH in patients > 65. Complication rates were comparable for both frail and non-frail cohorts.

The role of weight control in the management of type 2 diabetes mellitus: Bariatric surgery.

Diabetes mellitus is one of the major epidemics in the United States. It is heavily associated with obesity and multiple metabolic derangements that lead to long term morbidity, mortality as well as financial burden. Although medical therapy has been the mainstay in the management of diabetes mellitus, there remains a large portion of this patient population which struggles to obtain adequate glycemic control and long-term weight control with medical management alone. Bariatric surgery is a powerful tool in combating diabetes mellitus and affects glucose homeostasis through a variety of pathways. While it does provide a durable pathway for weight loss, improvement in glucose homeostasis is not only affected by the weight loss seen after bariatric surgery. Changes in gut hormone secretion, insulin regulation, and gut microbial composition also affect how these operations improve glucose homeostasis. Through improvement in the management of diabetes mellitus, comorbidities including cardiovascular disease, in turn demonstrate improvement. In this article, we will discuss the role of bariatric (metabolic) surgery as it relates to long term weight loss and the impact that weight loss has on improvement in diabetes mellitus.

Nationwide Bibliometric Analysis of Integrated Plastic Surgery Program Directors.

Studies have linked bibliometric indices with the academic level of plastic surgeons, but this relationship has not been explored with residency program directors (PDs). As teachers of the next generation, PDs' academic performance is an important component of residency program success. We sought to identify distinguishing characteristics of integrated plastic surgery programs, focusing on their PD bibliometric indices. Methods: We identified plastic surgery programs based on 2021 Doximity reputation and research output rankings, respectively, and then divided them into four quartiles (Q1-Q4). PD academic history and bibliometric indices (h-index, the number of publications, and citations) were collected through Doximity profiles and program websites: PubMed, Scopus, Google Scholar, American Society of Plastic Surgeons, and Accreditation Council for Graduate Medical Education. Results: Eighty-four programs were identified. There was a significant positive relationship between h-index, the number of publications, and type of research with reputation ranking (P < 0.05). After adjusting for years of experience post-training, h-index (OR = 1.24; P < 0.001) and the number of publications (OR = 1.05, P < 0.001) were significantly associated with reputation ranking. There was a statistically significant relationship between PD research fellowship completion and research output ranking (P < 0.01). After adjusting for years of experience post-training, h-index (OR = 1.05; P = 0.047) and the number of publications (OR = 1.01; P = 0.04) were significantly associated with research output ranking. Conclusion: Higher ranked programs tend to have PDs who have a strong record of scholarly activity, as evidenced by certain bibliometric indices.

Understanding Opioid Prescribing Practices of Resident Physicians.

BACKGROUND: To compare opioid prescribing practices of resident physicians across a variety of surgical and nonsurgical specialties; to identify factors which influence prescribing practices; and to examine resident utilization of best practice supplemental resources. METHODS: An anonymous survey which assessed prescribing practices was completed by residents from one of several different subspecialties, including internal medicine, obstetrics and gynecology, general surgery, neurosurgery, orthopedic surgery, and urology. Fisher's exact test assessed differences in prescribing practices between specialties. RESULTS: Only 35% of residents reported receiving formal training in safe opioid prescribing. Overall, the most frequently reported influences on prescribing practices were the use of standardized order sets for specific procedures, attending preference, and patient's history of prescribed opioids. Resident physicians significantly underutilize best practice supplemental resources, such as counseling patients on pain expectations prior to prescribing opioid medication; contacting established pain specialists; screening patients for opioid abuse; referring to the Prescription Monitoring Program; and counseling patients on safe disposal of unused pills (P < .001). DISCUSSION: The incorporation of comprehensive prescribing education into resident training and the utilization of standardized order sets can promote safe opioid prescribing.

Trends in Antibiotic Duration for Complicated Intra-Abdominal Infections : Adaptation to Current Guidelines.

INTRODUCTION: The 2017 surgical infection society (SIS) guidelines recommend 4 days of antibiotic therapy after source control for complicated intra-abdominal infections (cIAIs). Inappropriate exposure to antibiotics has a negative impact on outcomes in individual patients and populations. The goal of this study was to evaluate our institution's practice patterns and adherence to current antibiotic guidelines. METHODS: Medical records from 2010 to 2018 for cIAIs were examined. Complicated appendicitis and complicated diverticulitis cases were included. Exclusion criteria included other etiologies of IAIs, pediatric cases, and cancer operations. RESULTS: Fifty-nine complicated appendicitis cases and 96 complicated diverticulitis cases were identified. For all cases, antibiotic duration prior to publication of the SIS guidelines was significantly longer than post-SIS duration (appendicitis: 12.6 ± 1.1 days pre-SIS [n = 37] vs 9.0 ± 1.1 days post-SIS [n = 22], P = .01; diverticulitis: 15.1 ± 0.8 days pre-SIS [n = 49] vs 11.2 ± 0.5 post-SIS [n = 47], P = .04). Surgical management (SM) was associated with shorter duration of postsource control antibiotic exposure compared with percutaneous drainage (PD) for both appendicitis (SM 10.0 ± 1.2 days vs PD 13.4 ± 1.0 days, P = .02) and diverticulitis (SM 12.8 ± 1.5 days vs PD 16.0 ± 1.5, P = .07). Patients with complicated appendicitis received shorter duration of antibiotics when managed by acute care surgeons compared to general surgeons (8.4 ± 1.1 vs 11.9 ± 0.8, P = .02). CONCLUSION: Despite improvements after the SIS guidelines' publication, the antibiotic duration is still longer than recommended. Surgical intervention and management by acute care specialists were associated with a shorter duration of antibiotic exposure.

Patient Race and Insurance Status Do Not Impact the Treatment of Simple Mandibular Fractures.

INTRODUCTION: Health-care disparities have been reported throughout medical literature for decades. While blatant explicit bias is not prevalent, a substantial body of research has been published suggesting that systemic biases related to sex, race, income, and insurance status likely exist. To our knowledge, no study has assessed the impact of patient race and insurance status on clinical decision-making in facial fracture repair in the United States. Thus, the objective of this project was to assess if race and insurance status impacted whether patients obtained open or closed treatment of simple mandibular fractures. METHODS: Patients who had either open or closed treatment of mandibular fractures were extracted from the 2012 and 2013 National Inpatient Sample and analyzed. Patients who had a length of stay longer than 3 days or died during their inpatient stay were excluded. These exclusion criteria were used to control for patients with polytrauma as well as complicated fractures. Univariate analysis was undertaken to elucidate different variable associations with the type of reduction performed. All covariates were then entered into a multivariable logistic regression model to test the variables simultaneously. RESULTS: Patients with simple condylar, alveolar border, and closed mandibular fractures were more likely to undergo closed reduction (CR) on univariate analysis, as were patients with female gender and a fall mechanism (P value < .05). African Americans, Hispanics, and patients without insurance were more likely to undergo open reduction on univariate analysis (P value < .05). Multivariate analysis demonstrated that patients with simple condylar, subcondylar, alveolar border, or closed mandibular fractures were more likely to undergo a CR, as were patients with female gender and a firearm or fall mechanism (P < .05). However, neither race nor insurance status demonstrated a statistically significant association with closed or open reduction. CONCLUSION: Anatomic location and mechanism of injury were the variables found to be significantly associated with patients undergoing open reduction versus CR of simple mandibular fractures-not race or insurance status.

Global Contributions and Trends in Research within the Top-ranked Plastic Surgery Journal.

BACKGROUND: We aimed to longitudinally study the relative research contributions of US and international plastic surgeons by evaluating publications within the premier plastic surgery journal over the last 2 decades. We hypothesized that even with an increased pressure to publish in this journal, the relative research contributions from American plastic surgeons will continue to be the largest overall and in all subspecialties. METHODS: Data for the surgical subspecialty, corresponding author's country of origin, and region were extracted from all original articles in 2 randomly selected monthly issues of Plastic & Reconstructive Surgery (PRS) from the last 2 decades to evaluate longitudinal trends. Data were also extracted from all of the original articles published in PRS for the last 3 years to analyze the recent distribution of research output. RESULTS: During the last 2 decades, the relative proportion of total original articles written by US authors has increased. They have published proportionally more articles in the Reconstructive and Breast field while publishing relatively less in the hand/peripheral nerve field. From the first decade of analysis, US authors wrote relatively fewer articles in the hand/peripheral nerve field, whereas in the second decade, the US authors wrote relatively fewer articles in the Experimental field. In the last 3 years, US authors published relatively fewer articles in the Experimental and Cosmetic fields. CONCLUSIONS: Each country's scientific productivity in PRS is related to funding, interest, patients' demand, and healthcare market pressure. In this study, we see that these factors influence trends within research publications over the last 2 decades.

Antithrombotic prescriptions for many general surgery patients significantly increases the likelihood of post-operative bleeding complications.

BACKGROUND: The investigators hypothesized that despite cessation recommendations for peri-operative antithrombotic management in the elective setting, the use of these drugs is likely associated with increased odds for bleeding complications. METHODS: Humana® insurance claims (22 million covered lives) from 2007 through 2017 were analyzed. Only patients undergoing elective general surgery procedures were included. Patient Safety Indicator 09 (PSI-09) coding for post-operative hemorrhage and hematoma were analyzed. RESULTS: Despite the existence of peri-operative management guidelines, patients prescribed antithrombotic agents were 2.3 times more likely to develop post-operative bleeding complications (OR: 2.3436, 95% CI: 2.2155-2.4792, P < 0.0001). Nearly all antithrombotics prescribed in the pre-operative period led to a two-fold increased likelihood of post-operative bleeding-the odds ratios of enoxaparin and rivaroxaban approached seven. CONCLUSION: The data should remind surgeons to closely monitor the peri-operative management and post-operative course of patients pre-operatively prescribed antithrombotics-especially enoxaparin and rivaroxaban given the high risk of postoperative bleeding complications.

Properdin homeostasis requires turnover of the alternative complement pathway.

Properdin is a plasma protein and is also released from neutrophil granules following stimulation. At inflammatory sites it can bind bacteria and apoptotic bodies to trigger alternative pathway (AP) activation. Principles governing properdin homeostasis are unknown. We monitored properdin during AP activation and in complement-deficient mice. There was a >90% reduction of properdin in the Crry single-knockout mice (Crry SKO). These membrane complement regulatory protein-deficient mice feature accelerated AP turnover, leading to reduced C3 and fB. Injecting cobra venom factor into wild-type mice activated the AP and led to the consumption of C3, fB, and properdin. However, and unexpectedly, properdin was also deficient in C3(-/-), fB(-/-), and fD(-/-) mice. It was present in C1q(-/-), C4(-/-), and C5(-/-) mice. These findings implicate AP turnover in the maintenance of basal levels of properdin in the blood. To explore the mechanism, classical pathway-activating immune complexes were infused. Within 10 min, properdin was partially restored in fB(-/-) but not in C3(-/-) mice. Markedly reduced properdin in mice deficient in an AP component and its partial restoration by activating C3 suggest a requirement for continuous C3 activation via AP tickover to maintain properdin homeostasis. The mechanism underlying this C3-dependent process was not identified. Engagement of C3a and C5a receptors was ruled out. These findings represent an instructive example of how a positive regulator of an innate immune recognition and effector pathway is controlled. A rationale for such a means to supply properdin for immune reactions is proposed.
