Concordance and survival implications of preoperative subclassification of T3 rectal cancers by depth of mesorectal invasion using a 5-mm cut-off point with endorectal ultrasound and magnetic resonance imaging.
BACKGROUND: Validated rectal cancer staging groups T3 tumours in a single stage and depth of mesorectal invasion subclassification is not standard practice. Our aim is to report concordance between magnetic resonance imaging (MRI) and endorectal ultrasound (ERUS) for preoperative staging of T3 rectal tumours using a 5-mm cut-off point and possible survival implications. METHODS: Prospective cohort study including patients staged preoperatively as cT3 by ERUS or magnetic resonance imaging. The maximum depth of penetration beyond the outer longitudinal muscle layer was measured according to a 5-mm cut-off point. Concordance rate and Kappa coefficient were calculated for both techniques.

Is laparoscopic approach still a risk factor for postappendectomy intra-abdominal abscess?
Background The impact of laparoscopic appendectomy (LA) on the incidence of intra-abdominal abscess (IAA) remains controversial. We aimed to identify risk factors for postappendectomy IAA and assess the impact of appendectomy approach in postoperative morbidity. Methods A retrospective single-center study including consecutive patients who underwent appendectomy for acute appendicitis between 2015 and 2018 was performed. Demographic, clinical, intraoperative, and perioperative variables were collected. Univariate and multivariate analyses was performed to detect independent risk factors for IAA. Comparison of LA and open appendectomy was conducted, and propensity score model (PSM) was used …
