Long-Term Outcomes of Component Separation for Abdominal Wall Hernia Repair.

Importance: Component separation is a reconstructive technique used to facilitate midline closure of large or complex ventral hernias. Despite a contemporary surge in popularity, the incidence and long-term outcomes after component separation remain unknown.

Objective: To evaluate the incidence and long-term outcomes of component separation for abdominal wall hernia repair.

Comparisons of 30-day outcomes after ventral hernia repair by body mass index and surgical approach: a retrospective cohort study.

Introduction: Obesity is a known risk factor for postoperative complication after ventral or incisional hernia repair (VIHR). Whether minimally invasive techniques can mitigate this risk for certain patients remains unknown. This study investigates whether MIS approaches offer advantages in reducing any medical or surgical complication after VIHR across clinically meaningful BMI categories.

Understanding patient experiences to improve care for females groin hernia.

Background: Thousands of females undergo inguinal hernia repair annually, yet females have been excluded from prior clinical trials evaluating inguinal hernia repairs. Research shows females face worse outcomes after hernia repair compared to males, including higher recurrence rates, increased chronic pain, and limited data to guide treatment. Prospective studies focused on optimizing outcomes for females are critically needed.

Long-term patient reported outcomes after robotic, laparoscopic, and open ventral hernia repair.

Introduction: Current evidence demonstrates questionable incremental benefit of robotic abdominal wall (ventral) hernia repair when compared to other approaches. However, data are mainly limited to 30-day outcomes and do not capture long-term patient reported outcomes (PROs) where the robotic may provide distinct advantages.

Methods: We analyzed patients who underwent ventral hernia repair from January 2020-September 30, 2022 in the Michigan Surgical Quality Collaborative Core Optimization Hernia Registry (MSQC-COHR).

Heterogeneity in the surgical approach to recurrent abdominal wall hernias: an opportunity for quality improvement.

Background: Despite being a challenging and morbid clinical problem, operative approaches to recurrent abdominal wall hernia repairs receive little attention. Given this, we performed a retrospective study to evaluate surgical techniques of recurrent abdominal wall hernias requiring reoperation.

Methods: Adult patients from the Michigan Surgical Quality Collaborative Core Optimization Hernia Registry (MSQC-COHR) were included in this study.

SAGES White Paper on the importance of diversity in surgical leadership: creating the fundamentals of leadership development (FLD) curriculum.

Background: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) has long recognized and championed increasing diversity within the surgical workplace. SAGES initiated the Fundamentals of Leadership Development (FLD) Curriculum to address these needs and to provide surgeon leaders with the necessary tools and skills to promote diversity, equity, and inclusion (DEI) in surgical practice. In 2019, the American College of Surgeons issued a request for anti-racism initiatives which lead to the partnering of the two societies.

Paraesophageal hernia recurrence following repair: making the case for reoperative surgery in a propensity-matched cohort.

Background: Paraesophageal hernia repairs (PEHRs) have high rates of radiographic recurrence, with some patients requiring repeat operation. This study characterizes patients who underwent PEHR to identify the factors associated with postoperative symptom improvement and radiographic recurrence. We furthermore use propensity score matching to compare patients undergoing initial and reoperative PEHR to identify the factors predictive of recurrence or need for reoperation.

Optimizing ergonomics during open, laparoscopic, and robotic-assisted surgery: A review of surgical ergonomics literature and development of educational illustrations.

Background: The surgical profession is plagued with a high prevalence of work-related musculoskeletal disorders. While numerous interventions have been tested over the years, surgical ergonomics education is still uncommon.

Methods: The available literature on surgical ergonomics was reviewed, and with input from surgeons, recommendations from the review were used to create pictorial reminders for open, laparoscopic, and robot-assisted surgical modalities.

Mesh overlap for ventral hernia repair in current practice.

Introduction: Sufficient overlap of mesh beyond the borders of a ventral hernia helps prevent hernia recurrence. Guidelines from the European Hernia Society and American Hernia Society recommend ≥ 2 cm overlap for open repair of < 1-cm hernias, ≥ 3-cm overlap for open repair of 1-4-cm hernias, ≥ 5-cm overlap for open repair of > 4-cm hernias, and ≥ 5-cm overlap for all laparoscopic ventral hernia repairs. We evaluated whether current practice reflects this guidance.

Life after "no": barriers to behavior change for persons declined hernia repair due to high-risk features.

Introduction: Delaying an elective operation to mitigate risk factors improves patient outcomes. Elective ventral hernia repair is one such example. To address this issue, we developed a pre-operative optimization clinic to support high-risk patients seeking elective ventral hernia repair.

Conversion to Roux-En-Y Gastric Bypass: a successful means of mitigating reflux after laparoscopic sleeve gastrectomy.

Introduction: Laparoscopic sleeve gastrectomy (LSG) has become the most common bariatric procedure due to the technical ease and weight loss success of the operation. However, there has been concern that LSG contributes to gastroesophageal reflux disease (GERD) postoperatively with a proportion of patients requiring conversion to a Roux-En-Y Gastric Bypass (RYGB). The objective of this study was to characterize the patients who underwent revision in our hospital system and to better understand pre-operative predictors of GERD and revision.

Updated guideline for closure of abdominal wall incisions from the European and American Hernia Societies.

Background: Incisional hernia is a frequent complication of abdominal wall incision. Surgical technique is an important risk factor for the development of incisional hernia. The aim of these updated guidelines was to provide recommendations to decrease the incidence of incisional hernia.

The Aerosolization of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2): Phase I.

Introduction: The degree to which Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is aerosolized has yet to be determined. The aim of this study is to prove methods of detection of aerosolization of SARS-CoV-2 in hospitalized patients in anticipation of testing for aerosolization in procedural and operative settings.

Methods: In this prospective study, inpatients with SARS-CoV-2 were identified.

Multicenter analysis of laparoscopic versus open umbilical hernia repair with mesh: outcomes and quality of life (QoL).

Introduction: Umbilical hernia repair (UHR) is a common operation with varying surgical approaches. Laparoscopic (LUHR) and open (OUHR) operations are routinely performed, but their impact on quality of life (QoL) is not well described. Our aim was to evaluate perioperative outcomes and QoL of LUHR versus OUHR.

Robot-assisted ventral sacral Tarlov cystectomy; A case report.

Introduction And Importance: Although asymptomatic Tarlov cysts (TCs) are reported in up to 13% of the population, symptomatic TCs are rare (less than 1%), making the management of the symptomatic cysts controversial. The most common location of symptomatic TCs is sacral nerve roots where they can cause pelvic, perineal chronic discomfort and pain, and lower extremity sensory and motor changes. Ventral (intrapelvic retroperitoneal) sacral TCs are extremely rare with no management recommendations.

Factors Predicting Increased Length of Stay in Abdominal Wall Reconstruction.

Background: Enhanced recovery after surgery (ERAS) programs have become increasingly popular in general surgery, yet no guidelines exist for an abdominal wall reconstruction (AWR)-specific program. We aimed to evaluate predictors of increased length of stay (LOS) in the AWR population to aid in creating an AWR-specific ERAS protocol.

Methods: A prospective, single institution hernia center database was queried for all patients undergoing open AWR (1999-2019).

A multiparametric activity profiling platform for neuron disease phenotyping and drug screening.

Patient stem cell-derived models enable imaging of complex disease phenotypes and the development of scalable drug discovery platforms. Current preclinical methods for assessing cellular activity do not, however, capture the full intricacies of disease-induced disturbances and instead typically focus on a single parameter, which impairs both the understanding of disease and the discovery of effective therapeutics. Here, we describe a cloud-based image processing and analysis platform that captures the intricate activity profile revealed by GCaMP fluorescence recordings of intracellular calcium changes and enables the discovery of molecules that correct 153 parameters that define the amyotrophic lateral sclerosis motor neuron disease phenotype.

Outcomes and CT scan three-dimensional volumetric analysis of emergent paraesophageal hernia repairs: predicting patients who will require emergent repair.

Introduction: Elective repair versus watchful waiting remains controversial in paraesophageal hernia (PEH) patients. Generation of predictive factors to determine patients at greatest risk for emergent repair may prove helpful. The aim of this study was to evaluate patients undergoing elective versus emergent PEH repair and supplement this comparison with 3D volumetric analysis of hiatal defect area (HDA) and intrathoracic hernia sac volume (HSV) to determine risk factors for increased likelihood of emergent repair.

Development and Validation of Image-Based Deep Learning Models to Predict Surgical Complexity and Complications in Abdominal Wall Reconstruction.

Importance: Image-based deep learning models (DLMs) have been used in other disciplines, but this method has yet to be used to predict surgical outcomes.

Objective: To apply image-based deep learning to predict complexity, defined as need for component separation, and pulmonary and wound complications after abdominal wall reconstruction (AWR).

Design, Setting, And Participants: This quality improvement study was performed at an 874-bed hospital and tertiary hernia referral center from September 2019 to January 2020.
