Purpose: Numerous clinical practice guidelines and consensus statements have been published in hernia surgery, however, there is still a need for high-quality evidence to address remaining unanswered questions. The aim of this study was to conduct research priority setting through a modified Delphi process to identify a list of top research priorities in hernia surgery.

Methods: A structured literature review of clinical practice guidelines was performed by the steering committee.

Background: Venous thromboembolism is a significant cause of morbidity and mortality among patients undergoing ventral hernia repair. Several risk-assessment models have been developed to predict venous thromboembolism risk for various surgical procedures. However, these models do not include hernia-specific risk factors.

Background: As the population ages, more older adults are presenting for surgery. Age-related declines in physiological reserve and functional capacity can result in frailty and poor outcomes after surgery. Hence, optimizing perioperative care in older patients is imperative.

Background: Many surgical risk assessment tools emphasize patient-specific risk factors. Our objective was to use a hernia-specific database to assess risk factors of complications in ventral hernia repair (VHR) focusing on hernia-specific and procedural factors.

Methods: The ACHQC database was queried for elective VHR in adults from 2012 to 2023.

Background: In January 2023, significant changes were implemented to ventral hernia repair Current Procedural Terminology codes, with new codes replacing previous codes. The new codes were assigned a 0-day global period. The impact of these changes on clinical productivity remains unclear.

Background: Preoperative optimization cut-offs are frequently utilized to determine eligibility for elective ventral hernia repair. Our objective was to assess the relationship between gender, race, and socioeconomic status and preoperative optimization goals.

Methods: We queried our institutional database for adults with ventral hernia diagnoses between 2016 and 2021.

Background: Ergonomic development and awareness are critical to the long-term health and well-being of surgeons. Work-related musculoskeletal disorders affect an overwhelming majority of surgeons, and various operative modalities (open, laparoscopic, and robotic surgery) differentially affect the musculoskeletal system. Previous reviews have addressed various aspects of surgical ergonomic history or methods of ergonomic assessment, but the purpose of this study is to synthesize ergonomic analysis by surgical modality while discussing future directions of the field based on current perioperative interventions.

Background: Smoking has been shown to negatively affect surgical outcomes, so smoking cessation prior to elective operations is often recommended. However, the effects of smoking status on inguinal hernia repair outcomes have not been extensively studied. Hence, we investigated the association between smoking status and short-term adverse outcomes following inguinal hernia repair.

Background: The SAGES Guidelines Committee has implemented processes for Quality Assessment of SAGES-endorsed guidelines, with the aim of improving the quality of published guidelines.

Methods: We provide details of the processes developed, using standardized tools for assessing the methodological quality of practice guidelines. As an example, we describe the application of our processes to the recent multi-societal GERD consensus guideline.

Introduction: Different approaches and mesh positions are used for minimally invasive ventral hernia repair (MIS-VHR). Our aim was to evaluate the trends and short-term outcomes of intraperitoneal onlay mesh (IPOM), preperitoneal, and retromuscular repairs for small ventral hernias.

Methods: We conducted a retrospective cohort study using the Abdominal Core Health Quality Collaborative (ACHQC).

Introduction: Elevated preoperative glycated hemoglobin (HbA1c) is believed to predict complications in diabetic patients undergoing ventral hernia repair (VHR). Our objective was to assess the association between HbA1c and outcomes of VHR in diabetic patients.

Methods: We conducted a retrospective cohort study using the Abdominal Core Health Quality Collaborative (ACHQC) database.

Introduction: There are a paucity of data regarding the safety of laparoscopic inguinal hernia repair in patients on antiplatelet and anticoagulant therapy (APT/ACT). We aim to compare the postoperative outcomes of laparoscopic (LIHR) vs. open repair of inguinal hernias (OIHR) in patients on APT/ACT.

Introduction: Partial nephrectomy (PN) is associated with a non-negligible risk of postoperative cardiovascular morbidity and mortality. Identification of high-risk patients may enable optimization of perioperative management and consideration of alternative approaches. The authors aim to develop a procedure-specific cardiovascular risk index for PN patients and compare its performance to the widely used revised cardiac risk index (RCRI) and AUB-HAS2 cardiovascular risk index.

Background: The utility of preoperative computed tomography for urgent abdominal wall hernia repair is unclear. This study tests the hypothesis that there is no difference in patient outcomes for acutely incarcerated ventral or inguinal hernias diagnosed by preoperative computed tomography versus clinical assessment alone.

Methods: This retrospective cohort analysis included 270 adult patients undergoing urgent repair of ventral or inguinal hernia.

Introduction: Patients with coagulopathy requiring emergent appendectomy constitute a challenging patient population. It is unclear whether laparoscopic appendectomy (LA) is as safe as open appendectomy (OA) in these patients.

Methods: We queried the ACS-NSQIP database for adults with coagulopathy undergoing emergent appendectomy from 2014 to 2017.

Objectives: Radical cystectomy (RC) is a complex urologic procedure performed for the treatment of bladder cancer and causes significant morbidity. Wound dehiscence (WD) is a major complication associated with RC and is associated with multiple risk factors. The objectives of this study are to identify clinical risk factors for incidence of WD and develop a risk-prediction model to aid in patient risk-stratification and improvement of perioperative care.

Introduction: Recent studies have shown that software-generated 3D stone volume calculations are better predictors of stone burden than measured maximal axial stone diameter. However, no studies have assessed the role of formula estimated stone volume, a more practical and less expensive alternative to software calculations, to predict spontaneous stone passage (SSP).

Methods: We retrospectively included patients discharged from our emergency department on conservative treatment for ureteral stone (≤10 mm).

Purpose: Volumetric analysis is being increasingly utilized in the preoperative evaluation of complex incisional hernias. Three-dimensional (3D) reconstruction of abdominal computed tomography (CT) scan has been used to obtain surface area (SA) and volume (Vol.) measurements, while others have used simple mathematical formulas to obtain SA and Vol.

Background: Confocal laser endomicroscopy (CLE) is a novel endoscopic adjunct that allows real-time in vivo histological examination of mucosal surfaces. By using intravenous or topical fluorescent agents, CLE highlights certain mucosal elements that facilitate an optical biopsy in real time. CLE technology has been used in different organ systems including the gastrointestinal tract.
