Risk of venous thromboembolic complications in pregnant trauma patients: A matched cohort study.

Background: Trauma and pregnancy are both risk factors for venous thromboembolism (VTE). We hypothesized that pregnant blunt trauma patients would have a higher incidence of VTE complications compared with matched nonpregnant females.

Methods: We conducted a retrospective cohort study using National Trauma Data Bank data from 2017 to 2022.

Contrasting roles of different mismatch repair proteins in basal-like breast cancer.

The mismatch repair (MMR) pathway is known as a tumor suppressive pathway and genes involved in MMR are commonly mutated in hereditary colorectal or other cancer types. However, the function of MMR genes/proteins in breast cancer progression and metastasis are largely unknown. We found that MSH2, but not MLH1, is highly enriched in basal-like breast cancer (BLBC) and that its protein expression is inversely correlated with overall survival time (OS).

Is Cystogastrostomy a Definitive Operation for Pancreatitis Associated Pancreatic Fluid Collections?

Background: Pancreatic-enteric drainage procedures have become standard therapy for symptomatic pancreatic pseudocysts and walled-off pancreatic necrosis. The need for pancreatic resection after cyst-enteric drainage procedure in the event of recurrence is not well studied. This study aimed to quantify the percentage of patients requiring resection due to recurrence after surgical cystogastrostomy and identify predictors of drainage failure.

"Infiltrative" Versus "Mass-Forming" Pancreatic Cancer: A New Radiological Classification System for Pancreatic Head Ductal Carcinoma and Its Pathological Correlation.

Purpose: Resectability in localized pancreatic ductal adenocarcinoma (PDAC) is deemed through radiological criteria. Despite initial evaluation classifying tumors as "resectable," they often have ill-defined borders that can result in more extensive cancer than predicted on final pathology analysis. We attempt to categorize these tumors radiologically and define them as "infiltrative" and contrast them to more well-defined or "mass-forming" tumors and assess their correlation with surgical oncological outcomes.

Esophagectomy in octogenarians: is it at a cost?

Background: Surgical intervention in the geriatric population has a higher risk of perioperative morbidity and mortality due to frailty, comorbidities, and lack of compensatory physiologic reserve. The literature on esophagectomy in octogenarians is limited and there is concern about elderly patients being with-held surgery. The purpose of this study is to analyze the outcomes of esophagectomies for esophageal cancer in octogenarians to assess the safety of esophagectomy in this population.

Blueprint for safe transition from a low- to high-volume pancreatic surgery center.

We describe a straightforward model to implement a high volume specialty surgery program at a community hospital. Using pancreatic surgery as an example, we employed published processes in three arenas. First, mandatory multidisciplinary tumor board presentations captured all the patients considered for surgery.

A self-selecting prophecy: prevalence of burnout in surgical fellows.

Background: Burnout has become a prominent topic, yet there are limited data on the manifestation of this phenomenon among surgical fellows. The goal of this study is to elucidate the prevalence of burnout and determine if there are protective or predisposing factors in surgical fellowship training.

Methods: A confidential electronic survey was distributed to Fellowship Council accredited fellows during the 2020-2021 academic year.

Transduodenal resection for duodenal adenomas may be an underutilized tool - A single institution experience.

Background: Duodenal adenomas are pre-malignant lesions. Transduodenal resection and pancreaticoduodenectomy remain the only two surgical options. The optimal surgical management remains controversial between these two strategies.

Whipple pancreatoduodenectomy: A technical illustration.

Background: The Whipple procedure in its current form owes its evolution to the groundbreaking and innovative work of giants in the field of surgery. From being a multistep procedure with high morbidity and mortality, it is now ubiquitously performed in a single setting, often offered via minimally invasive approaches. Training to perform this procedure is an arduous task, and different training paradigms vary significantly.

Fosfomycin vs Ertapenem for Outpatient Treatment of Complicated Urinary Tract Infections: A Multicenter, Retrospective Cohort Study.

Background: We sought to determine the comparative efficacy of fosfomycin vs ertapenem for outpatient treatment of complicated urinary tract infections (cUTIs).

Methods: We conducted a multicenter, retrospective cohort study involving patients with cUTI treated with outpatient oral fosfomycin vs intravenous ertapenem at 3 public hospitals in Los Angeles County between January 2018 and September 2020. The primary outcome was resolution of clinical symptoms 30 days after diagnosis.

To Wrap or Not to Wrap After Heller Myotomy.

Background And Objectives: The primary aim of this study is to assess the necessity of fundoplication for reflux in patients undergoing Heller myotomy for achalasia. The secondary aim is to assess the safety of the robotic approach to Heller myotomy.

Methods: This is a single institution, retrospective analysis of 61 patients who underwent robotic Heller myotomy with or without fundoplication over a 4-year period (January 1, 2015 - December 31, 2019).

Hiatal Hernia After Esophagectomy: A Single-Center Retrospective Analysis of a Rare Postoperative Phenomenon.

Development of a post-esophagectomy hiatal hernia (PEHH) is a rare, but problematic, sequela with the current reported prevalence ranging up to 20%. To determine the incidence rate of PEHH at our institution, a retrospective review of all transhiatal esophagectomies performed from 2012 to 2020 was conducted. Demographic, operative, and oncologic data were collected, rates of PEHH were calculated, and characteristics of subsequent repair were reviewed and analyzed.

Spine surgery complexity score predicts outcomes in 671 consecutive spine surgery patients.

Background: The spine surgery complexity score (SSCS), previously reported by us, is a simple grading system to predict postoperative complications and hospital length of stay (LOS). This scale is based on the technical difficulty of the spinal procedures being performed.

Methods: We performed a retrospective chart review to validate SSCS in 671 consecutive patients undergoing spine procedures at a quaternary academic hospital.

Investigating Factors at Play in Hepatopancreatobiliary Fellowship Selection: Beliefs versus Reality.

Background: Selection biases affecting candidate matches to fellowship programs directly influence diversity within the surgical community. The review of selection bias has never been distinctively investigated in the Hepatopancreatobiliary (HPB) surgery community. This study seeks to (i) evaluate factors affecting selection of candidates to HPB fellowships, (ii) examine explicit biases among program directors and faculty of HPB programs in North America, and (iii) compare the demography of the HPB faculty and recently graduated fellows to general surgery residents.

AP-2α Regulates S-Phase and Is a Marker for Sensitivity to PI3K Inhibitor Buparlisib in Colon Cancer.

Activating protein 2 alpha (AP-2α; encoded by ) functions as a tumor suppressor and influences response to therapy in several cancer types. We aimed to characterize regulation of the transcriptome by AP-2α in colon cancer. CRISPR-Cas9 and short hairpin RNA were used to eliminate expression in HCT116 and a panel of colon cancer cell lines.

68Ga-DOTATATE PET/CT compared to standard imaging in metastatic neuroendocrine tumors: a more sensitive test to detect liver metastasis?

Purpose: 68Ga-DOTATATE PET is becoming a popular imaging technique for detecting neuroendocrine tumors (NETs). The sensitivity and specificity of 68Ga-DOTATATE PET compared to standard cross-sectional imaging with triple phase CT or MRI with Eovist has not been studied extensively.

Methods: 68Ga-DOTATATE PET scans ordered at our institution between 11/2017 and 7/2018 were reviewed.

Hepatopancreatobiliary Fellowship Graduates: Where Do They Stand today?

Background: The Americas Hepato-Pancreato-Biliary Association (AHPBA) Education and Training Committee standardized a Hepatopancreatobiliary (HPB) Surgery Fellowship certification process in 2010. Several classes of fellows have since graduated from HPB, combined Society of Surgical Oncology/AHPBA, and combined American Society of Transplant Surgeons/AHPBA fellowships, but there is little information on their career outcomes. We seek to offer long-term data on the careers of HPB fellowship graduates.

Advanced Gastrointestinal Surgery Fellowship Programs: Filling a Gap in Surgical Training?

Objective: The goal of the 1-year Advanced Gastrointestinal (AGI) surgery fellowship is to train the general surgeon to perform advanced and complex operations that they had insufficient experience with in residency training. This study examines the case logs of AGI fellows that have completed Society for Surgery of the Alimentary Tract (SSAT)-sponsored Fellowship Council (FC)-accredited AGI fellowships to determine the role of these fellowships in providing complex gastrointestinal operative experience.

Design/participants: Institutional Review Board-approved retrospective surgical case log analysis.

Minimally Invasive Esophagectomy for Achieving R0.

Background: Minimally invasive esophagectomy (MIE) is becoming increasing popular. Since it was introduced, there has been debate about its safety and efficacy when compared with open esophagectomies (OE). We sought to compare the oncologic outcomes of MIE and OE in this study specifically with regards to margin status and nodal retrieval.

AP-2γ Is Required for Maintenance of Multipotent Mammary Stem Cells.

Mammary gland ductal morphogenesis depends on the differentiation of mammary stem cells (MaSCs) into basal and luminal lineages. The AP-2γ transcription factor, encoded by Tfap2c, has a central role in mammary gland development but its effect in mammary lineages and specifically MaSCs is largely unknown. Here, we utilized an inducible, conditional knockout of Tfap2c to elucidate the role of AP-2γ in maintenance and differentiation of MaSCs.

Overcoming the Arduous Transition for Robotic Hepatopancreatobiliary Cases: A Multi-Procedure Learning Curve Study Utilizing CUSUM Analysis.

Background/objective: Quick optimization and mastery of a new technique is an important part of procedural medicine, especially in the field of minimally invasive surgery. Complex surgeries such as robotic pancreaticoduodenectomies (RPD) and robotic distal pancreatectomies (RDP) have a steep learning curve; therefore, findings that can help expedite the burdensome learning process are extremely beneficial. This single-surgeon study aims to report the learning curves of RDP, RPD, and robotic Heller myotomy (RHM) and to review the results' implications for the current state of robotic hepatopancreaticobiliary (HPB) surgery.

Frailty predicts worse outcomes after intracranial meningioma surgery irrespective of existing prognostic factors.

Objective: Frailty has been recognized as a predictor of adverse surgical outcomes across multiple surgical disciplines, but until now the relationship between frailty and intracranial meningioma surgery has not been studied. The goal of the present study was to determine the relationship between increasing frailty (determined using the modified Frailty Index [mFI]) and intracranial meningioma resection outcomes (including hospital length of stay [LOS], discharge location, and reoperation and readmission rates).

Methods: This is a single-center retrospective cohort study of patients who underwent intracranial meningioma resection between August 2012 and May 2018.
