Methods A total of 121 patients with B-PLG diagnosed by CDU combined with HFU between January 2008 and November 2011 were randomly selected. All of the patients underwent the surgery and had the record of surgical pathological examination results, which were compared with the results of the ultrasonography in order to evaluate the diagnostic accuracy of CDU combined with HFU for B-PLG. Results In 121 patients with B-PLG diagnosed by CDU combined with HFU before the surgery, cholesterol polyp was found in 62 (51.24%), infective polyp was found in 27 (22.31%), adenoma was found in 6 (4.96%), adenocarcinoma was found in 3 (2.48%), gallstones was found in 14 (11.57%), adenomyosis was found in 3 (2.48%), the wall structure gland disorder was found in 3 (2.48%), and submucosal soft nodules was found in 3 (2.48%) after the surgical pathological examination. Coincidence rate between CDU combined with HFU diagnosis and surgical pathological diagnosiswas 78.51% (95/121), and the misdiagnosis rate of CDU combined with HFU was 21.49% (26/121). Conclusion The accuracy of CDU combined with HFU diagnosing B-PLG is high, which can help to prevent precancerous lesion of gallbladder cancer.
The expression of p21, p53, bcl-2 oncoprotein was evaluated using immunohistochemistry in 40 patients with gallbladder carcinoma and 8 patients with gallbladder adenomous polyp. In the study, the positive rate of expression of p21, p53 and bcl-2 oncoprotein was 52.5%, 52.5% and 70.0% respectively in gallbladder carcinoma, while, in gallbladder polyp, they were 0%, 0% and 100% respectively. The positive rate of expression of p53 oncoprotein was significantly higher in poor-differentiated adenocarcinomas than in well-differentiated ones (Ｐ＜0.05). The converse was true for bcl-2 oncoprotein. The positive rate of expression of p21 and p53 oncoprotein was significantly higher in metastatic group than in non-metastatic one. These results suggest that the patients with the expression of p21, p53 might be of poor-prognosis.
目的探讨腹腔镜与开腹胆囊切除术对患者肝功能及免疫功能的影响。 方法根据手术方式将84例胆囊良性病变患者分为腹腔镜胆囊切除术组（LC组，50例）及开腹胆囊切除术组（OC组，34例），比较2组患者手术前后肝功能及免疫功能指标的变化。 结果2组患者肝功能在手术前后不同时间点的差异均无统计学意义（P＞0.05）；LC组患者术后免疫功能各指标与术前比较无明显变化（P＞0.05），OC组CD3+、CD4+及CD4+/CD8+在术后1 d及3 d均较术前明显降低（P＜0.05），术后7 d恢复至术前水平（P＞0.05）。 结论LC术可引起患者术后肝功能短暂异常，但对免疫功能无明显影响，可作为胆囊切除的首选术式。
Objective To analyze clinicopathologic characteristics of 1 008 patients with gallbladder polyps by minimally invasive gallbladder-preserving surgery, and to explore hemostatic effect of 0–4 ℃ cold saline plus different concentrations norepinephrines in flushing gallbladder mucosa bleeding. Methods The clinical data of 1 008 patients with gallbladder polyps by the minimally invasive gallbladder-preserving surgery from 2009 to 2016 in the General Hospital of Xinjiang Military Command were retrospectively analyzed. The clinicopathologic types of gallbladder polyps and the relationship between the operation time and the recurrence of gallbladder polyps were analyzed, the hemostatic effects of 0–4 ℃ cold saline plus different concentrations (0, 16, 24, and 30 mg/L) norepinephrines in flushing gallbladder mucosa bleeding (The hemostatic effect was reflected by the time of flushing gallbladder mucosa bleeding) were compared. Results One thousand patients with non-tumorous gallbladder polyps successfully underwent the minimally invasive gallbladder-preserving surgery, another 8 cases patients with tumorous gallbladder polyps underwent the cholecystectomy immediately. There were 128 cases of single polyps and 880 cases of multiple polyps. The polyp diameters of 910 cases were 5–10 mm and 98 cases were 10–15 mm. The pathological analysis indicated that there were 912 (90.5%) cases of the cholesterol polyps, 74 (7.3%) cases of the inflammatory polyps, 14 (1.4%) cases of the adenoid hyperplasia, and 8 (0.8%) cases of the neoplastic polyps ［adenoma 6 cases, adenocarcinoma (T0N0M0) 2 cases］. The gallbladder polyps recurrences were found in 30 (3.0%) cases during 1–8 years of follow-up (average 4 years), all of them were the multiple and cholesterol polyps. The flushing gallbladder mucosa bleeding time of 0–4 ℃ cold saline plus 0, 16, 24, and 30 mg/L concentraions norepinephrine was (44±5) min, (33±6) min, (17±5) min, and (17±4) min in the 125, 230, 555, and 98 patients with gallbladder polyps, respectively. The time of flushing gallbladder mucosa bleeding between the other concentration groups had significant difference (P<0.05) except for between the 24 mg/L concentration group and the 30 mg/L concentration group (P>0.05). The operation time was (62±21) min and (60±19) min of the 30 patients with gallbladder polyps recurrence and the 970 patients without gallbladder polyps recurrence, which had no significant difference (P>0.05). Conclusions Cholesterol polyp is a common pathological type of gallbladder polyp, inflammatory polyp and adenomyosis polyp are uncommon, and multiple polyps are common. Hemostatic effects of 0–4 ℃ cold saline plus different concentraions norepinephrine in flushing gallbladder mucosa bleeding are desirable, expecially at a 24 mg/L concentraion norepinephrine is the most effective. No correlation is found between operation time and recurrence of gallbladder polyp.
Gallbladder polypoid lesion (GPL) is a common gallbladder disease, mainly including tumor lesions such as gallbladder cancer and gallbladder adenoma and non-tumor lesions such as cholesterol polyps and gallbladder adenomyomatosis. Contrast-enhanced ultrasound (CEUS) can improve the diagnostic accuracy of GPL. This paper reviews the application progress of CEUS in the diagnosis of gallbladder cancer, gallbladder adenoma, gallbladder cholesterol polyps and gallbladder adenomyosis, and the limitations of CEUS in the diagnosis of GPL.
With the development and popularization of imaging technology, the discovery of gallbladder lesions has become common, among which non-neoplastic lesions (such as gallbladder stones, cholecystitis, gallbladder polyps, gallbladder adenomyosis, etc.) are common but sometimes the imaging manifestations are not specific, and there are many kinds of such diseases, so accurate imaging diagnosis is still quite challenging. Familiarity and understanding of the typical imaging manifestations of these diseases will help to improve the early and accurate diagnosis and help to distinguish them from gallbladder malignant diseases, which is of great significance to the diagnosis, guiding treatment and prognosis of patients.
ObjectiveTo explore the related risk factors of polypoid lesions of gallbladder (PLG) in civil aviation flight cadets and the health management measures for the risk factors. MethodsRetrospective analysis of the 2022 flight annual medical students, according to the B ultrasound examination results have PLG, divided into PLG group (n=128) and non-PLG group (n=150), collect the basic data of the students, and establish a multivariate logistic regression equation model to analyze the related risk factors of gallbladder polypoid lesions. ResultsThe results of univariate analysis showed that there was no significant difference between groups with hypertension, hyperlipidemia and hyperglycemia (P>0.05), but with age and body mass index, high total bilirubin in serum and hyperuricemia, regular schedule and diet, and sufficient exercise (P<0.05). The results of multivariate logistic regression equation model analysis showed that age, high serum total bilirubin, hyperuricemia, irregular sleep and rest, irregular diet and lack of exercise were independent risk factors for PLG. ConclusionsAge, high serum total bilirubin, hyperuricemia, irregular work and rest, irregular diet and lack of exercise are the main reasons for PLG in civil aviation flight cadets. Intervention and prevention of risk factors can effectively ensure their health and flight safety.
