Gallbladder Malignancy

Summary A gallbladder polyp (GP) is defined as an elevation of the gallbladder mucosa that protrudes into the gallbladder lumen. Gallbladder polyps (GPs) have an estimated prevalence in adults of 0.3–12.3%. However, only 5% of polyps are considered “true” GPs that have malignant potential or are even already cancerous. The most important imaging method for diagnosis and follow-up of GPs is transabdominal ultrasound, but it fails to discriminate between true and pseudo polyps at a clinically relevant level. Although gallbladder cancer (GBC) arising from polyps is a rare event, malignancy is significantly more common among polyps from a size of 10 mm. In light of this, the consensus, which is reflected in current guidelines, is that surgery should be considered for polyps of 10 mm or greater. However, 10 mm is an arbitrary cutoff, and high-quality evidence to support this is lacking. Lowering the threshold for cholecystectomy when patients have additional risk factors for gallbladder malignancy may improve the cancer detection rate in polyps smaller than 10 mm. Nevertheless, the evidence behind this is also weak. This review shows the shortcomings in the available evidence and underlines the decision-making process regarding the surgical indication, surveillance, or both.

Abstract Background Gallbladder polyps are common findings on ultrasound with a prevalence between 0.3-9.5%. Their significance is not clear but are theorised to have potential risk of transformation into gallbladder malignancy which have poor prognosis if not caught early. Current guidelines recommend surveillance of polyps and that laparoscopic cholecystectomy should be offered if certain criteria are met. Most patients are asymptomatic and regular reviews in clinic is time consuming for patients and adds to strain on services. This study looks at the use of virtual clinics in gallbladder polyp surveillance. Methods Since January 2019 patients identified with gallbladder polyps have been added to virtual clinic. Each patient is added to a database which is maintained by one upper GI surgeon. Current guidelines are followed: laparoscopic cholecystectomy is offered if polyps are greater than 1cm, there is an increase greater than 2mm between scans, and in high-risk groups or in symptomatic patients. All other patients are offered interval scans as per guidelines and a template letter is generated informing patients of their scan results and date of their follow up scan. Results Since January 2019, 70 patients have been identified to have gallbladder polyps. Of these 48 patients so far have benefitted from involvement from follow up in virtual clinic to date, this has resulted in 88 clinic appointments being saved. 12 patients have undergone laparoscopic cholecystectomy due to increase in size of their gallbladder polyps or secondary to symptoms. 7 patients have been lost to follow up, 2 discharged due to the gallbladder polyps disappearing and the other 49 remain under surveillance in the virtual clinic. Conclusions Long term polyp surveillance can be time consuming for both the patient and clinician. This model of a virtual clinic maintains clear communication with patients about their scan findings, the risks associated and plans for future scans. This is an efficient method of monitoring these patients that has good compliance and identifies patients appropriate for surgery.

The most common mesenchymal tumors are gastrointestinal stromal tumors (GISTs), which have malignant potential and can occur anywhere along the gastrointestinal system. Imaging methods are important and indispensable of GISTs in diagnosis, risk staging, therapy, and follow-up. The recommended imaging method for staging and follow-up is computed tomography (CT) according to current guidelines. Artificial intelligence (AI) applies and elaborates theses, procedures, modes, and utilization systems for simulating, enlarging, and stretching the intellectual capacity of humans. Recently, researchers have done a few studies to explore AI applications in GIST imaging. This article reviews the present AI studies in GISTs imaging, including preoperative diagnosis, risk stratification and prediction of prognosis, gene mutation, and targeted therapy response.

Retrospective Multicenter Study

Summary:Aim: For the surgical therapy of differentiated thyroid cancer precise guidelines are applied by the German medical societies. In a retrospective multicenter study, we investigated the following issues: Are the current guidelines respected?. Is there a difference concerning the surgical radicalism and the outcome?. Does the perioperative morbidity increase with the higher radicalism of the procedure?. Patients, methods: Data gained from 102 patients from 17 regional referral hospitals who underwent surgery for thyroid cancer and a following radioiodine treatment (mean follow up: 42.7 [24-79] months) were analyzed. At least 71 criterias were analyzed in a SPSS file. Results: 46.1% of carcinomas were incidentally detected during goiter surgery. The thyroid cancer (papillary n = 78; follicular n = 24) occurred in 87% unilateral and in 13% bilateral. Papillary carcinomas <1 cm were detected in 25 cases; in five of these cases (20%) contralateral carcinomas <1 cm were found. There were significant differences concerning the surgical radicalism: a range from hemithyroidectomy to radical thyroidectomy with lateral neck dissection. Analysis of the histopathologic reports revealed that lymph node dissection was not performed according to guidelines in 55% of all patients. The perioperative morbidity was lower in departments with a high case load. The postoperative dysfunction of the recurrent laryngeal nerve (mean: 7.9% total / 4.9% nerves at risk) variated highly, depending on differences in radicalism and hospitals. Up to now these variations in surgical treatment have shown no differences in their outcome and survival rates, when followed by radioiodine therapy. Conclusion: Current surgical regimes did not follow the guidelines in more than 50% of all cases. This low acceptance has to be discussed. The actual discussion about principles of treatment regarding, the socalled papillary microcarcinomas (old term) has to be respected within the current guidelines.

BACKGROUND: Lung ultrasound (LUS) is a bedside technique that can be used on diagnosis and follow-up of neonatal respiratory diseases. However, there are rare reports on the ultrasound features of bronchopulmonary dysplasia (BPD) which is one of the most common chronic lung diseases in preterm infants. OBJECTIVE: To describe the ultrasound features of different BPD levels, and to investigate the value of ultrasound in evaluating moderate-to-severe BPD. METHODS: In this prospective cohort study, newborns of less than 37 weeks’ gestational age in neonatal intensive care unit (NICU) were included. The LUS characteristics including pleural line, alveolar-interstitial syndrome (AIS), retrodiaphragmatic hyperechogenicity and diaphragmatic morphology were observed and recorded. The reliability of LUS in evaluating moderate and severe BPD were compared and calculated. RESULTS: A total of 108 infants were enrolled in our study: 39, 24, 29, 16 infants had non, mild, moderate and severe BPD. The median(IQR) pleura thickness in the moderate-to-severe BPD group was 1.7(1.6–1.85) mm, which was thicker than that in the none-to-mild BPD infants (P <  0.001), meanwhile the proportions of rough pleural lines, diffuse AIS, retrodiaphragmatic hyperechogenicity, small cysts above the diaphragm and rough diaphragm in the moderate-to-severe BPD group were also higher than those in none-to-mild BPD group (86.7% vs 36.5, 57.8% vs 7.9%, 37.8% vs 0, 33.3% vs 0, P <  0.001). In evaluating moderate-to-severe BPD, rough pleura had 91.1% (95% confidence interval [CI]: 0.793–0.965) in sensitivity, 91.3% (95% CI: 0.797–0.966) in negative predictive value (NPV), and 66.7% (95% CI: 0.544–0.771) in specificity. Small cysts had 100% (95% CI: 0.941-1) in specificity, 100% (95% CI: 0.816-1) in PPV, and 37.8% in sensitivity (95% CI: 0.251–0.524). Rough diaphragm had 100% (95% CI: 0.943-1) in sensitivity, 100% (95% CI: 0.796-1) in PPV and 33.3% (95% CI: 0.211–0.478) in specificity. CONCLUSIONS: Depending on its unique advantages such as convenient, no radiation and repeatable, LUS is a valuable imaging method in assessing the severity of BPD, especially in moderate and severe BPD.

Haemorrhage in patients with haemophilia is common after minor trauma but may occur spontaneously. Despite the diversity of bleeding sites, spontaneous haemothorax, on a non-traumatic basis, is an exceedingly rare event and only a few cases had been reported. We present a case of a 43-year-old man with a history of haemophilia A who had pleuritic chest pain for 1 day without significant history of trauma. Diagnostic thoracentesis showed bloody pleural fluid in which neither abnormal cell nor organism was found. He was treated by cryoprecipitate replacement and therapeutic thoracentesis for releasing haemothorax. After discharge, the patient returned for follow-up with complete radiological resolution. Regarding the consequences of retained haemothorax from conservative approach and the procedure-related bleeding of given therapeutic intervention in haemothorax making its management in patients with haemophilia to be more challenging. Our case illustrates a conservative treatment of spontaneous haemothorax in patient with haemophilia resulting in a good clinical outcome.

Abdominal Aortic Dissection

Isolated acute abdominal aortic dissection is a relatively rare event. Its natural history is not fully understood and its optimal treatment is not established. Open surgery represents the most described treatment but endovascular intervention has had increasing application. Isolated chronic abdominal aortic dissection  is even less described in the literature. We describe three patients with isolated chronic abdominal aortic dissection who underwent endovascular treatment in our institution. Mean age at presentation was 82 years. Indication for surgical intervention was aneurismal degeneration. Mean aortic diameter at presentation was 46.7 mm. There was no perioperative mortality or reinterventions. Mean follow-up was 5.3 years (2-12 years). Late reintervention was needed in one patient, eight years after initial surgery, due to type 1 endoleak. According to our experience, endovascular intervention represents an effective and durable treatment option in isolated chronic abdominal aortic dissection. However, long-term follow-up is mandatory. Furthermore, larger studies are still needed to understand this disease and its adequate treatment.

Abstract Background Early detection and treatment of cardiometabolic diseases (CMD) in high-risk patients is a promising preventive strategy to anticipate the increasing burden of CMD. The Dutch guideline ‘the prevention consultation’ provides a framework for stepwise CMD risk assessment and detection in primary care. The aim of this study was to assess the outcome of this program in terms of newly diagnosed CMD. Methods A cohort study among 30 934 patients, aged 45–70 years without known CMD or CMD risk factors, who were invited for the CMD detection program within 37 general practices. Patients filled out a CMD risk score (step 1), were referred for additional risk profiling in case of high risk (step 2) and received lifestyle advice and (pharmacological) treatment if indicated (step 3). During 1-year follow-up newly diagnosed CMD, prescriptions and abnormal diagnostic tests were assessed. Results Twelve thousand seven hundred and thirty-eight patients filled out the risk score of which 865, 6665 and 5208 had a low, intermediate and high CMD risk, respectively. One thousand seven hundred and fifty-five high-risk patients consulted the general practitioner, in 346 of whom a new CMD was diagnosed. In an additional 422 patients a new prescription and/or abnormal diagnostic test were found. Conclusions Implementation of the CMD detection program resulted in a new CMD diagnosis in one-fifth of high-risk patients who attended the practice for completion of their risk profile. However, the potential yield of the program could be higher given the considerable number of additional risk factors—such as elevated glucose, blood pressure and cholesterol levels—found, requiring active follow-up and presumably treatment in the future.

Abstract Background: Women with unilateral breast cancer are at an increased risk for the development of contralateral breast cancers. We hypothesis that combined breast MRI would detect more contralateral synchronous breast cancer than conventional imaging alone, and resulted in less contralateral metachronous breast cancer during follow-up. Methods: In this case control analysis, we retrospectively collected two groups of patients for evaluating the effectiveness and value of adding pre-operative breast MRI to conventional breast images (mammography and sonography) for detection of contralateral synchronous breast cancer. The new metachronous contralateral breast cancer diagnosed during follow-up was prospectively evaluated and compared. Results: Group A (n=733) comprised patients who underwent conventional preoperative imaging and group B (n=735) combined with MRI were enrolled and compared. Seventy (9.5%) of the group B patients were found to have contralateral lesions detected by breast MRI, and 65.7% of these lesions only visible with MRI. The positive predictive value of breast MRI detected contralateral lesions was 48.8%. With the addition of breast MRI to conventional imaging studies, more surgical excisions were performed in contralateral breasts (6% (44/735) versus 1.4% (10/733), P< 0.01), more synchronous contralateral breast cancer detected (2.9% (21/735) versus 1.1% (8/733), P=0.02), and resulted in numerical less (2.2% (16/714) versus 3% (22/725), p=0.3) metachronous contralateral breast cancer during a mean follow-up of 102 months. Conclusions: Combining pre-operative breast MRI evaluation resulted in an increase of contralateral synchronous breast cancer detection, and a numerical less subsequent contralateral metachronous breast cancer occurrence compared to conventional imaging alone.
