Our purpose was to conduct a bibliometric study investigating the prevalence of underpowered randomized controlled trials (RCTs) in trauma surgery. ⋯ A concerningly large proportion of recently published RCTs in trauma surgery do not report a priori sample size calculations, do not meet enrollment targets, and are not adequately powered to detect even large effect sizes. There exists opportunity for improvement of trauma surgery study design, conduct, and reporting.

The etiology of diverticulitis is multifactorial and poorly understood. We estimated the familiality of diverticulitis using the Utah Population Database, a statewide database linking medical records with genealogy data. ⋯ Our results indicate that the first-, second-, and third-degree relatives of diverticulitis patients are at elevated risk of developing diverticulitis. This information may aid surgeons in counseling patients and family members about diverticulitis risk and can inform the development of future risk-stratification tools. Further work is needed to clarify the causal role and relative contribution of various genetic, lifestyle, and environmental factors in the development of diverticulitis.

Low anterior resection syndrome (LARS) is a well-described consequence of rectal cancer treatment. Studying the degree to which bowel dysfunction exists in the general population may help to better interpret to what extent LARS is related to disease and/or cancer treatment. Currently, North American LARS normative data are lacking. The aim of this study was to describe the prevalence of bowel dysfunction, as measured by the LARS score, and quality of life (QoL) in a reference North American sample. Quality of life was measured and associations between participant characteristics and LARS were identified. ⋯ Our study identified the baseline prevalence of LARS in asymptomatic adults who have not undergone a low anterior resection. These normative data will allow for more accurate interpretation of ongoing studies on LARS in North American rectal cancer patients.

The effect of lymphadenectomy around the recurrent laryngeal nerve (RLN) in open esophagectomy has been demonstrated with the efficacy index (EI). However, it remains unclear whether this effect exists for minimally invasive esophagectomy (MIE) in the prone position. The purpose of this study was to clarify whether the upper mediastinal lymphadenectomy contributed to improved prognosis in patients with esophageal squamous cell carcinoma. ⋯ Upper mediastinal lymphadenectomy contributes to improved prognosis with high EIs in MIE in the prone position.

Although patient-risk stratification is important for selecting individualized treatment for pancreatic ductal adenocarcinoma (PDAC), predicting the oncologic outcomes after surgery remains a challenge. In this study, we identified a nectin family gene panel (NFGP) that can accurately stratify oncologic outcomes in patients with PDAC. ⋯ This study established the predictive significance of NFGP for oncologic outcomes after surgery in PDAC. Our data demonstrate its clinical impact as a potent biomarker for optimal patient selection for individualized treatment strategies.
