Bariatric patients have a high prevalence of hiatal hernia (HH). HH imposes various difficulties in performing laparoscopic bariatric surgery. Preoperative evaluation is generally inaccurate, estab...

The aim of this study was to analyze dynamic patterns for scanning femoroacetabular impingement (FAI) radiographs in orthopedics, in order to better understand the nature of expertise in radiography. Seven orthopedics residents with at least two years of expertise and seven board-certified orthopedists participated in the study. The participants were asked to diagnose 15 anteroposterior (AP) pelvis radiographs of 15 surgical patients, diagnosed with FAI syndrome. Eye tracking data were recorded using the SMI desk-mounted tracker and were analyzed using advanced measures and methodologies, mainly recurrence quantification analysis. The expert orthopedists presented a less predictable pattern of scanning the radiographs although there was no difference between experts and non-experts in the deterministic nature of their scan path. In addition, the experts presented a higher percentage of correct areas of focus and more quickly made their first comparison between symmetric regions of the pelvis. We contribute to the understanding of experts’ process of diagnosis by showing that experts are qualitatively different from residents in their scanning patterns. The dynamic pattern of scanning that characterizes the experts was found to have a more complex and less predictable signature, meaning that experts’ scanning is simultaneously both structured (i.e. deterministic) and unpredictable.

(1) Background: Crohn’s disease (CD) and right-sided colorectal-carcinoma (CRC) are two common indications for right colectomies. Many studies have tried to identify risk factors associated with post-operative complications for both CD and CRC. However, data directly comparing the outcomes of the two are sparse. This study aims to compare the 30-day post-operative outcome after a right colectomy for CD versus CRC. Its secondary aim is to identify the factors associated with these outcomes for each group. (2) Methods: A retrospective cohort study of 123 patients who underwent a right colectomy for CD or CRC in a single institution between March 2011 and March 2016. (3) Results: There were no significant differences between the groups when comparing the overall complication rate, the median Clavien–Dindo score, reoperation rates and the length of hospitalization. The leak rate was higher in the Crohn’s group (13.95% (6/43) vs. 3.75% (3/80)), p = 0.049), although the stoma rate was the same (4/43 9.5%; 7/80 9.9%). (4) Conclusions: This study has shown that post-operative complication rate is similar for right colectomy in CD and CRC. However, Crohn’s disease patients did have a higher leak rate.

Background: Surgical resection in Crohn's disease is sometimes the only alternative treating disease complications or refractory disease. The implications of early resection on disease course are still debatable. We aimed to assess the influence of preoperative disease duration on long‐term postoperative disease course.Methods: A retrospective analysis of all Crohn's disease patients who underwent an elective primary ileocolic resection between 2010 and 2021 in a single tertiary medical center. The cohort was divided based on disease duration, Group A (47 patients) had a disease duration shorter than 3 years (median of 1 year) and Group B (139 patients) had a disease duration longer than 3 years (median of 11 years).Results: Surgeries were less complex among Group A as noted by higher rates of laparoscopic assisted procedures (68.1% vs. 45.3%, P = 0.006), shorter surgery duration (134 vs. 167 min, P < 0.0001) less estimated blood loss (72.5 vs. 333 mL, P = 0.016) and faster return of bowel function (3 vs. 4 days, P = 0.011). However, propensity score matching nullified all the differences. Younger age (OR = 0.86, P = 0.004), pre‐op steroids (OR = 3.69, P = 0.037) and longer disease duration (OR = 1.18, P = 0.012) were found to be independently significantly associated with severe complications. After a median follow‐up time of 71.38 months no significant differences were found between the groups in terms of endoscopic (P = 0.59), or surgical recurrences rates (P = 0.82).Conclusions: The main effect of preoperative short disease duration was noted within the surgical complexity; however, matching suggests confounders as cause of the difference. No significant long‐term implication was noted on disease recurrence.
