The effects of weight loss due to gastric banding and lifestyle modification on red blood cell aggregation and deformability in severe obese subjects

Objective:To investigate the changes in the aggregation index (AI) and the elongation index (EI), in severe obese subjects (MbObS) undergoing laparoscopic adjustable gastric banding (LAGB). AI and EI are measured by Laser assisted Optical Rotational Red Cell Analyzer (LORCA) and are markers of erythrocyte aggregation and deformability, respectively.Design and subjects:Before, 3 and 6 months after LAGB plus lifestyle changes (Mediterranean diet plus daily moderate exercise), we evaluated AI, EI, body mass index (BMI), total (ToT) cholesterol (Chol), high-density lipoprotein (HDL)-Chol, low-density lipoprotein (LDL)-Chol, triglycerides and fasting glucose and insulin levels in 20 MbObS. The Students t-test was used for comparisons between independent groups and the analysis of variance to assess differences in AI and EI at the 3 time points. Pearsons correlation coefficient was used to assess correlation among continuous variables and multiple linear regression analysis to assess predictive factors for AI and EI changes.Results:BMI and all blood parameters showed a statistically significant decline 3 and 6 months after LAGB as compared with basal, except for EI and HDL-Chol that significantly increased. Stepwise selection of predictors shows that at 3 and 6 months, EI values depended on HDL-Chol values at the same time point. In the EI model, blood glucose was also statistically significant at 6 months.Conclusion:Our data show a significant improvement in EI after LAGB-induced weight loss, which correlates with an improved lipid pattern and support the idea that the rapid weight loss induced by LAGB plus lifestyle changes might reduce the thromboembolic risk and the high mortality risk found in MbObS.

Retrobulbar metastasis from gallbladder carcinoma after laparoscopic cholecystectomy. A case report

Extra-abdominal metastases from gallbladder cancer are very rare; the sites outside the abdomen most frequently affected are the skin, bone and central nervous system. In the literature, only one case of orbital metastasis from gallbladder cancer has been reported, in a patient previously treated by open cholecystectomy. We report the case of a 53-year-old woman who underwent a laparoscopic cholecystectomy for symptomatic gallbladder stones. Postoperative histological examination revealed an unsuspected gallbladder adenocarcinoma. One month later she came to our observation after having developed diplopia and ophthalmic pain due to an orbital metastasis. We decided not to perform a surgical second look because of the already rapid dissemination of the malignant tumor. The few cases of uncommon gallbladder cancer metastases after laparoscopic cholecystectomy described in the literature are discussed, as well as the possible role of laparoscopy in the dissemination and localized seeding of malignant cells.

Laparoscopic treatment of simultaneous splenic lymphangioma and non-Hodgkin's lymphoma: report of a case.

We report, to the best of our knowledge, the first case of simultaneous splenic lymphangioma and non-Hodgkins B-cell lymphoma with liver and bone marrow involvement arising in a 69-year-old woman suffering from chronic hepatitis C infection treated with laparoscopic splenectomy followed by polychemotherapy. After 22 months from surgical treatment, the patient is alive without signs of residual disease. According to our experience, laparoscopic splenectomy followed by polychemotherapy seems to be an effective treatment for simultaneous splenic lymphangioma and non-Hodgkins B-cell lymphoma.

Successful endoscopic treatment of gastric phytobezoar: A case report

Highlights • Gastric bezoars are a rare condition.• Endoscopic fragmentation or aspiration is the best alternative among non invasive procedure.• Effective and rapid treatment in outpatient setting is described without short or long term complications.
