Introduction Investigations have demonstrated that trocar site hernia (TSH) is an under-appreciated complication of laparoscopic surgery, occurring in as many as 31%. We determined the incidence of fascial defects prior to laparoscopic appendectomy and its impact relative to other risk factors upon the development of TSH. Methods TSH was defined as a fascial separation of ≥ 1 cm in the abdominal wall umbilical region on abdominal computerized tomography scan (CT) following laparoscopic appendectomy. Patients admitted to our medical center who had both a preoperative CT and postoperative CT for any reason (greater than 30 days after surgery) were reviewed for the presence of TSH from May 2010 to December 2018. CT scans were measured for fascial defects, while investigators were blinded to film timing (preoperative or postoperative) and patient identity. Demographic information was collected. Results 241 patients undergoing laparoscopic appendectomy had both preoperative and late postoperative CT. TSH was identified in 49 (20.3%) patients. Mean preoperative fascial gap was 3.3 ± 4.3 mm in those not developing a postoperative hernia versus 14.8 ± 7.3 mm in those with a postoperative hernia ( P < .0001). Preoperative fascial defect on CT was predictive of TSH ( P < .001, OR = 1.44), with an Area Under the Curve (AUC) of .921 (95%CI: .88–.92). Other major risk factors for TSH were: age greater than 59 years ( P < .031, OR = 2.48); and obesity, BMI > 30 ( P < .012, OR = 2.14). Conclusions The incidence of trocar site hernia was one in five following laparoscopic appendectomy. The presence of a pre-existing fascial defect, advanced age, and obesity were strong predictors for the development of trocar site hernia.

Risk Of Malignancy

The next diagnostic step in cases of indeterminate radial probe endobronchial ultrasound (radial EBUS)-guided biopsy results remains uncertain. This study aimed to identify risk factors for malignancy based on clinical findings, chest computed tomography (CT), and radial EBUS images, and to estimate the risk of malignancy in lung nodules that showed indeterminate radial EBUS-guided biopsy results by constructing a nomogram. This retrospective study included 157 patients with indeterminate results on an initial radial EBUS biopsy performed at the Samsung Medical Center from January 2017 to December 2018, but with a definitive final diagnosis. Medical records, chest CT, radial EBUS images, and the final diagnoses were reviewed. Patients were randomly divided into training and validation sets. Factors related to malignancy were identified through logistic regression analysis, and a nomogram was constructed using the training set and subsequently applied to the validation set. Six factors in univariable and multivariable analyses, including upper lobe location, spiculation, satellite nodules, echogenicity, presence of dots or linear arcs, and patency of vessels and bronchi predicted malignancy. A nomogram was constructed based on these predictors. The area under the curve (AUC) value of the nomogram was 0.858 using the chest CT factors, which improved to 0.952 when radial EBUS factors were added. The calibration curve showed good agreement between the actual and nomogram-predicted malignancy outcomes. The utility of radial EBUS images for revealing risk factors of malignancy was confirmed. Furthermore, our nomogram was able to predict the probability of malignancy in lung nodules with indeterminate radial EBUS-guided biopsy results.

Abstract Aim Laparoscopy is common in abdominal surgery. Trocar site hernia (TSH) is a most likely underestimated complication. Among risk factors, obesity, the use of larger trocars and the umbilical trocar site has been described. In a previous study, CT scan in the prone position upon a ring was found to be a reliable method for the detection of TSH in obese. Our aim was to examine the incidence of TSH after gastric sleeve. Material and Methods 79 patients subjected to laparoscopic gastric sleeve in 2011-2016 were examined using CT in the prone position upon a ring. Symptoms of TSH were assessed using a digital survey. Results The incidence of trocar site hernia was 17 out of 79 (21,5 %), all at the umbilical trocar site. The mean follow-up time was 37 months. There was no clear correlation between symptomatic TSH and TSH on CT. Conclusions The incidence of TSH is high in this group of patients. Up to follow-up, none of the patients had been subjected to hernia repair. Although the consequence of trocar site hernia can be serious, the proportion of symptomatic TSH is unknown.

Trocar site hernia (TSH) is a type of incisional hernia occurring at the trocar sites after minimal invasive surgeries, most often in adult patients with non-sutured trocar sites. This is a case report of a 5 mm trocar site omental herniation six years after laparoscopic appendectomy in a nine-year-old boy to emphasize that incisions should be closed using fascial and cutaneous sutures, regardless of trocar size and localization, to prevent TSH. We conducted a brief review of the literature on this topic.

Abstract Background Laparoscopy is common in abdominal surgery. Trocar site hernia (TSH) is a most likely underestimated complication. Among risk factors, obesity, the use of larger trocars and the umbilical trocar site has been described. In a previous study, CT scan in the prone position was found to be a reliable method for the detection of TSH following gastric bypass (LRYGB). In the present study, our aim was to examine the incidence of TSH after gastric sleeve, and further to investigate the proportion of symptomatic trocar site hernias. Methods Seventy-nine patients subjected to laparoscopic gastric sleeve in 2011–2016 were examined using CT in the prone position upon a ring. Symptoms of TSH were assessed using a digital survey. Results The incidence of trocar site hernia was 17 out of 79 (21.5%), all at the umbilical trocar site. The mean follow-up time was 37 months. There was no significant correlation between patient symptoms and a TSH. Conclusions The incidence of TSH is high after laparoscopic gastric sleeve, a finding in line with several recent studies as well as with our first trial on trocar site hernia after LRYGB. Up to follow-up, none of the patients had been subjected to hernia repair. Although the consequence of a trocar site hernia can be serious, the proportion of symptomatic TSH needs to be more clarified.

High Grade Gliomas

SummaryA retrospective study was done to determine the incidence of and the risk factors predisposing to clinical venous thromboembolism (VTE) in patients treated for high grade gliomas. Medical records of 68 consecutive patients diagnosed and treated at Saint Francis Hospital and Medical Center from January 1986 to June 1991 were reviewed. The follow up was to time of death or at least 6 months (up to December 1991). All clinically suspected episodes of VTE were confirmed by objective tests. Sixteen episodes of VTE were detected in 13 patients for an overall episode rate of 23.5%. Administration of chemotherapy (p = 0.027, two tailed Fisher exact test) and presence of paresis (p = 0.031, two tailed Fisher exact test) were statistically significant risk factors for the development of VTE. Thrombotic events were more likely to occur in the paretic limb and this difference was statistically significant (p = 0.00049, chi square test, with Yates correction). No major bleeding complications were seen in the nine episodes treated with long term anticoagulation.We conclude that venous thromboembolic complications are frequently encountered in patients being treated for high grade gliomas and the presence of paresis and the administration of chemotherapy increases the risk of such complications.

Background: Stroke is a great public health problem in Ethiopia. According to reports, in-hospital stroke mortality was estimated to be 14.7% in Ethiopia. Despite this, in this country researches done on factors associated with stroke sub-types were inadequate. Objective: To assess the Characteristics and risk factors associated with stroke sub-types among patients admitted to JUMC. Methods and materials: A retrospective cross sectional study was conducted from May 2017 to May 2018 in stroke unit of Jimma University Medical Center. A total of 106 medical charts of patients diagnosed with stroke were reviewed. Checklist comprising of relevant variables was used to collect data. SPSS version 21 was employed for data entry and analysis. Chi-square test was used to point-out association and difference among stroke sub-types. The data was presented using text, tables and figures. Result: From a total of 106 patients, 67(63.2%) were men. The mean ± SD of age was 52.67±12.46 years, and no significant association was found. Of all the patients, 59(55.6%) had ischemic strokes and 47(44.4%) had hemorrhagic strokes. The most common risk factor in the patients was alcohol use with a prevalence of 69.9%. Of all the risk factors, only sex, cigarettes smoking and dyslipidemia were significantly associated to sub-types of stroke. Conclusion: Ischemic stroke was the most common subtype of stroke. Sex of patient, cigarette smoking and dyslipidemia are significantly associated with the two stroke subtypes.

The squash function in capsule networks (CapsNets) dynamic routing is less capable of performing discrimination of non-informative capsules which leads to abnormal activation value distribution of capsules. In this paper, we propose vertical squash (VSquash) to improve the original squash by preventing the activation values of capsules in the primary capsule layer to shrink non-informative capsules, promote discriminative capsules and avoid high information sensitivity. Furthermore, a new neural network, (i) skip-connected convolutional capsule (S-CCCapsule), (ii) Integrated skip-connected convolutional capsules (ISCC) and (iii) Ensemble skip-connected convolutional capsules (ESCC) based on CapsNets are presented where the VSquash is applied in the dynamic routing. In order to achieve uniform distribution of coupling coefficient of probabilities between capsules, we use the Sigmoid function rather than Softmax function. Experiments on Guangzhou Women and Children’s Medical Center (GWCMC), Radiological Society of North America (RSNA) and Mendeley CXR Pneumonia datasets were performed to validate the effectiveness of our proposed methods. We found that our proposed methods produce better accuracy compared to other methods based on model evaluation metrics such as confusion matrix, sensitivity, specificity and Area under the curve (AUC). Our method for pneumonia detection performs better than practicing radiologists. It minimizes human error and reduces diagnosis time.

Abstract Background The COVID-19 pandemic resulted in a transformation of clinical care practices to protect both patients and providers. These changes led to a decrease in patient volume, impacting physician trainee education due to lost clinical and didactic opportunities. We measured the prevalence of trainee concern over missed educational opportunities and investigated the risk factors leading to such concerns. Methods All residents and fellows at a large academic medical center were invited to participate in a web-based survey in May of 2020. Participants responded to questions regarding demographic characteristics, specialty, primary assigned responsibility during the previous 2 weeks (clinical, education, or research), perceived concern over missed educational opportunities, and burnout. Multivariable logistic regression was used to assess the relationship between missed educational opportunities and the measured variables. Results 22% (301 of 1375) of the trainees completed the survey. 47% of the participants were concerned about missed educational opportunities. Trainees assigned to education at home had 2.85 [95%CI 1.33–6.45] greater odds of being concerned over missed educational opportunities as compared with trainees performing clinical work. Trainees performing research were not similarly affected [aOR = 0.96, 95%CI (0.47–1.93)]. Trainees in pathology or radiology had 2.51 [95%CI 1.16–5.68] greater odds of concern for missed educational opportunities as compared with medicine. Trainees with greater concern over missed opportunities were more likely to be experiencing burnout (p = 0.038). Conclusions Trainees in radiology or pathology and those assigned to education at home were more likely to be concerned about their missed educational opportunities. Residency programs should consider providing trainees with research or at home clinical opportunities as an alternative to self-study should future need for reduced clinical hours arise.
