Background. This prospective randomized study compares the incidence of silent deep venous thrombosis (DVT) among 2 groups of patients who underwent laparoscopic bariatric surgery. The first group received mechanical thromboprophylaxis only, while the second group received a combination of mechanical and chemical thromboprophylaxis. Methods. This study included 150 morbidly obese patients who underwent primary one-stage laparoscopic bariatric surgery (sleeve gastrectomy and mini-gastric bypass) over a 6-month period. Patients were randomly assigned to 2 groups: group A (n = 75) was subjected to mechanical thromboprophylaxis in the form of perioperative elastic stockings on both lower limbs and early postoperative ambulation, and group B (n = 75) was subjected to combined mechanical thromboprophylaxis and chemical thromboprophylaxis in the form of 40 mg subcutaneous enoxaparin 12 hours before surgery and postoperative enoxaparin (40 mg subcutaneous every 24 hours) for 2 weeks. Bilateral lower limb venous duplex was done for all patients before discharge, on the second and fourth weeks postoperatively, to detect silent DVT. Results. Nine patients out of 150 patients developed silent DVT (6%). All patients among group A were subjected to mechanical thromboprophylaxis only (12%) [ P = .247, relative risk: .45, 95% confidence interval; .37-.62]. There was no silent DVT among group B who received combined mechanical and chemical thromboprophylaxis. No bleeding complications were reported in both groups. Conclusion. Combined mechanical and mechanical thromboprophylaxis is effective and safe in the prevention of silent DVT after laparoscopic bariatric surgery. Trial registration: The trial was registered in the Thai Clinical Trials Registry (TCTR20200127002) on January 20, 2020 retrospectively.

Background:We focused on determining the most reliable transthoracic ultrasound (TUS) criteria that can predict malignancy of the pleural and peripheral pulmonary lesions and correlating our data with CT and cyto-histological findings. Sixty-nine patients (38 males and 31 females) were enrolled in our prospective study. They were divided into group I (48 patients), which included patients with pleural effusion, and group II (21 patients), which included patients with peripheral pulmonary lesions. All patients underwent chest X-ray (postero-anterior and lateral views), transthoracic ultrasound (TUS), CT chest, guided Tru-cut or surgical biopsies and histopathology, and/or needle aspiration and cytology. Results: In group I, the presence of pleural nodularity was a predictor of malignancy with significant statistical difference (b value < 0.001) and receiver operating curve (ROC) curve analysis showed pleural thickening cutoff value of 7 mm at a maximum combined sensitivity and specificity of 75% and 80% respectively and area under the curve 0.825. In group II, distorted intralesional vascular pattern, pleural, and chest wall invasion were statistically significant ultrasonographic malignant predictors (b values are <0.001, 0.016, and 0.004 respectively).Conclusion: TUS is a valuable and safe complementary method in differentiation between benign and malignant pleural effusion and peripheral pulmonary lesions but is not a substitute for CT.
