To evaluate the ultrasound imaging characteristics and diagnostic criteria for acute abdominal Meckel's diverticulum disease (MD), we retrospectively analyzed the ultrasonic characteristics, clinical data of 58 cases of pathologically proved MD from January 2009 to May 2012. We found that among all the 58 patients, 21 patients were diagnosed with the preoperative clinical diagnosis of MD. Fourteen cases of MD inflammation with acute appendicitis were evaluated by pathological examinations after the surgery. We also found 4 cases of MD with perforation, 15 cases of MD with intussusceptions, 14 cases MD with intestinal obstruction, 5 cases of MD secondary to intestinal obstructionor intestinal necrosis, and 5 cases of MD without any obvious complications. Emergency ultrasound examinations revealed 8 cases of simple MD, 1 case of MD with intussusceptions, 9 cases of MD with acute appendicitis, 12 cases of MD with intestinal obstruction, 2 cases of MD with intussusceptions and intestinal obstruction, 1 case of MD with omphalocele and 1 case of MD with abdominal abscess. The emergency sonographic findings suggested that MD was relatively fixed bowel or thick-walled cystic mass, with one end connected to small intestine, and the other end connected to the blind side, at the periumbilicus region or at the lower right abdomen. A conclusion could be drawn that MD is difficult to be detected by ultrasound (detection rate was about 15.5%), and MD with complications such as intussusceptions, intestinal obstruction, acute appendicitis can usually be more easily detected (detection rates were 24.1%, 24.1% and 15.5%, respectively). Sonography is a simple, effective way to make diagnosis and differential diagnosis of MD with different acute abdomen symptoms from other disease.
Objective To investigate the clinical and imaging manifestations, laboratory examination, diagnosis, treatment and prognosis of hepatic tuberculosis, and improve the understanding of hepatic tuberculosis. Methods One case of hepatic tuberculosis that treated by author was reported, at the same time, the domestic literatures were retrieved from 2000 to 2015, 158 cases of hepatic tuberculosis were collected, and the clinical manifestations, imaging examination, diagnosis and prognosis of 159 cases were analyzed. Results ①In 159 cases, male patients were in the majority, male and female ratio was about 2:1. Symptom with fever (68.55%), liver discomfort (43.40%), loss of appetite and fatigue (40.88%) were the main performance. ②Results of laboratory examination: erythrocyte sedimentation rate increased (71.76%), abnormal liver function (58.49%), and lower hemoglobin (52.83%). ③The comparation of imaging diagnosis: the positive rates of CT and B-ultrasound were no significant difference (P＞0.05), there existed significantly difference between MRI, B-ultrasound and CT, MRI had a higher positive rate (P＜0.05). ④The preoperative diagnosis rate of hepatic tuberculosis about 13.84%, was low. The misdiagnosis rate was high, during which liver cancer were the most common misdiagnosed. Diagnosis mainly depends on pathological examination. ⑤Medical treatment was the main treatment, and it’s effect was good. Conclusions Hepatic tuberculosis lacked specific clinical manifestations, and the imaging features of various, the diagnostic rate of hepatic tuberculosis was low, and the misdiagnosis rate was high. In order to definite it, histopathological examination is necessary. The first choice of treatment is drug therapy, which is good.
Objective To understand pathogenesis, clinical manifestations, diagnosis, treatment, and prognosis of metaplastic breast cancer (MBC), and to provide some new ideas for clinical diagnosis and treatment, and exploration of scientific research for it. Method The relevant literatures of the latest research on MBC were reviewed and analyzed. Results At present, the pathogenesis of the MBC was still uncertain. The incidence of the MBC was lower, and it’s clinical manifestations were not specific. Compared with the invasive breast cancer, the tumor diameter was larger, the growth was faster, the differentiation degree was lower, the risks of the local and distant metastases were higher, while the lymph node metastasis was rare. Because of the clinical manifestation, auxiliary examination, and imaging examinations were lack of specificity, the diagnosis was difficult. Although the preoperative puncture could provide a reliable diagnosis evidence, it was difficult for distinguishing and accurate diagnosis due to it’s more subtypings. Some of the specific molecular targets could provide a help for it. At present, the modified radical mastectomy was often performed, the axillary lymph node metastasis was relatively rare in the MBC, so the sentinel lymph node biopsy was more important in the treatment of the MBC. The therapeutic effect was limited by the endocrine therapy, targeted therapy, or neoadjuvant chemotherapy and was poor by the systemic chemotherapy. Although the radiotherapy and chemotherapy could improve the overall survival and prolong the disease-free survival and control the local recurrence, the difference of it’s therapeutic effect was great due to the complex MBC typing. Conclusions MBC is a highly malignant and strongly invasive tumor, and it has more subtypings. Clinical manifestation and preoperative examination are lack of specificity, hence it is easy for misdiagnosis or missed diagnosis. Unified treatment guideline is lack of, prognosis is poor. So, it needs to explore some new treatment methods and formulate standardized treatment guidelines in order to achieve a better therapeutic effect.
Objective To investigate the clinicopathological features and clinical subtypes of Peutz-Jeghers syndrome (PJS) in Chinese cases. Methods The clinical and pathological data of 295 patients with PJS who were treated in Air Force General Hospital from Nov. 1994 to Aug. 2017 were retrospectively analyzed and a multifactor statistical study was carried out on. Results Two hundreds and ninety-five patients with PJS belonged to 7 nationalities and came from 26 provinces and urban areas. 99.0% (292/295) of the patients had black spots on the lip and buccal mucosa, and the median occurrence time was 2 years old (0–33 years). The median age of inital diagnosis and treatment was 15 years old (1–45 years). The median interval time between the occurrence of black spots and abdominal symptoms was about 10 years (0–45 years). PJS hamartoma polyps were found in alimentary canals of 293 patients (99.3%), and 96.9% distributed in the duodenum and small intestine (n=284), 90.4% distributed in the colorectal (n=265), 79.9% distributed in the stomach (n=234). Patients of black spot appearing at age <3 years and (or) initial treatment at age <14 years were classified as early-onset subtype, otherwise they could be included in delayed-onset subtype. Conclusions The clinical features of PJS are prominent and the harm of PJS hamartoma polyps is serious. The black spots on the lip and buccal mucosa can be used as an early warning signal to divide the PJS patients into 2 clinical subtypes, which should be differentiated in clinical therapy and follow-up strategy.
ObjectiveTo re-understand the nerve sheath tumors of the breast, to improve its diagnosis and cure rate.MethodSearched the relevant literatures of nerve sheath tumors of the breast, to analyze and summarize the origin, etiology, clinical manifestations, imaging characteristics, pathological characteristics, treatment, and prognosis of this disease.ResultsNerve sheath tumors of the breast was a very rare disease, which originated in the neuromembrane Snowwang cells. its specific cause was unknown and clinical manifestations were not specific, and other breast diseases were difficult to identify, such as leaf ybrilloma, mammary vascular epidermal cytoma, breast fibroids, and so on. Imaging data could provide some reference value, but the gold standard relied on pathology and immunohistochemical examination. Surgery could cure benign nerve sheath tumors of the breast, but there was a possibility of malignant changes that required follow-up after surgery. Malignant neuroblastoma was mainly surgically removed, supplemented by chemotherapy, which could effectively prevent the recurrence of tumor and distant metastasis. The prevention of nerve sheath tumors of the breast could be referred to breast cancer screening.ConclusionsDuring clinical practice, we need to understand the diagnosis and treatment of nerve sheath tumors of the breast to achieve early detection, early diagnosis, and early treatment, as well as improve the diagnosis rate and cure rate of the disease, in order to protect women’s physical and mental health.
Objective To summarize the research progress in the diagnosis and treatment of pancreatic cystic neoplasms (PCNs). Method The guidelines and literatures related to the diagnosis and treatment of PCNs were collected and reviewed. Results At present, there was still no clear method to distinguish the types of PCNs and their benign and malignant, and there was still a dispute between domestic and foreign guidelines on the diagnosis and treatment of PCNs. Conclusion Clinical researchers still need to carry out more research, provide higher quality evidence, resolve the disputes existing in different guidelines, standardize the diagnosis and treatment process of PCNs, thus, PCNs can be identified early, diagnosed accurately and intervened in time.
ObjectiveTo investigate the research progress of diagnosis and treatment of iliac vein compression syndrome (IVCS) so as to find the optimal diagnosis and treatment method in clinic. MethodLiterature about etiology, pathophysiology, clinical manifestations, diagnosis and treatment of IVCS in recent years was reviewed. ResultsIVCS was one of the pelvic vein obstructive diseases. The compression of left common iliac vein by right common iliac artery was more common in clinic, and it could also cause partial or complete occlusion of the iliac vein due to other external pressures. Clinical manifestations mainly included venous pain, edema, varicose veins, venous ulcer, skin pigmentation, and other skin nutritional changes. The examination methods mainly included color Doppler ultrasound, computed tomography venography, magnetic resonance venography, intravascular ultrasound, and venography. The treatment method had been changed from the original open venous reconstruction to intravascular treatment. Endovascular treatment was included thrombolysis, thrombectomy, percutaneous mechanical thrombectomy, balloon angioplasty, and endovascular stent treatment or combination treatment according to whether they were combined with iliac-femoral venous thrombosis or not. ConclusionBased on the existing researches, intravascular ultrasound is the first choice to diagnose and guide the intravascular treatment, and iliac vein stenting is an effective method for the treatment of IVCS with a good long-term patency and obvious symptom improvement.
