Long-term prognosis of laparoscopic gastrectomy for patients on antithrombotic therapy: a retrospective cohort study.

PURPOSE: Few studies have reported on the interactions between gastrectomy and antithrombotic therapy, especially the long-term prognosis. We aimed to clarify the short- and long-term prognosis of gastrectomy for patients on antithrombotic therapy. METHODS: We reviewed the perioperative data and survival rate of patients who underwent laparoscopic distal gastrectomy (LDG) at our institute between 2010 and 2013. RESULTS: There were 119 patients enrolled in this retrospective study: 31 who were taking antithrombotic drugs (antithrombotic therapy (ATT) group), and 88 who were not (non-ATT group). The mean age was significantly higher in the ATT group than in the non-ATT group. No significant differences were observed in the amount of intraoperative bleeding or blood hemoglobin level after surgery between the groups. Bleeding complications occurred in only one patient from the ATT group, and the postoperative complication rate was comparable between the groups. During follow-up, cerebrovascular or cardiovascular events developed in 19.4% of the ATT group patients and 4.5% of the non-ATT group patients; however, there were no significant differences in the 5-year overall survival rates between the groups (ATT group, 76.9%; non-ATT group, 82.9%). CONCLUSIONS: Antithrombotic therapy did not affect the short-term or long-term prognosis of patients after LDG.

Tumor Screening, Incidence, and Treatment for Patients with Severe Motor and Intellectual Disabilities.

BACKGROUND: The increasing age of patients with severe motor and intellectual disabilities (SMID) has become a serious concern. Few studies have investigated tumor treatment in this population. METHODS: Tumor treatments for 12 SMID patients were examined. RESULTS: Blood tests and ultrasonography were useful for screening. With regard to treatment, surgery for SMID patients was performed in the same manner as for patients without SMID, and the results were generally satisfactory, without major complications. Typically, cancer was diagnosed at an advanced stage, and many metachronous double cancers were observed. CONCLUSIONS: Treatment yielded satisfactory results for patients with SMID and their families. Future studies should examine the clinical significance of screening and tumor operative method for patients with SMID.

The arrival time of indocyanine green in tissues can be a quantitative index because of its correlation with tissue oxygen saturation: A clinical pilot study.

Indocyanine green (ICG) fluorescence angiography has recently been reported useful as a method for predicting intestinal blood flow and may reduce anastomotic leakage. However, the quantification method for ICG fluorescence angiography has not been established. We usually measure the tissue oxygen saturation (StO2 ) in the intestinal tract via near-infrared spectroscopy, as it is able to measure the oxygen concentration accurately and immediately shows objective data. In this study, we propose that the time to reach the anastomotic site after intravenous ICG injection is an effective parameter for quantifying ICG fluorescence angiography from the comparison to the data of StO2 in the intestinal tract.

Hypertensive Cardiomyopathy with Congestive Heart Failure in an Infant with Unilateral Wilms Tumor: A Case Report.

Wilms tumor (WT) is the most common malignant kidney tumor in children. High blood pressure is seen in up to 55% of children with WT. However, hypertensive cardiomyopathy with congestive heart failure due to WT is remarkably rare, with only several cases reported worldwide. In this report, a pediatric case of WT with hypertension causing hypertensive cardiomyopathy and congestive heart failure is presented. An 8-month-old male child with abdominal distension was seen by his primary physician. He was referred to our hospital for further examination and treatment. Abdominal contrast-enhanced computed tomography demonstrated a weakly enhancing, large abdominal mass, which was larger than 12 cm. Two-dimensional transthoracic echocardiography showed a diffuse hypokinetic left ventricle. The patient was diagnosed with cardiomyopathy caused by hypertension. Open surgical resection of the mass was successfully performed. His postoperative course was uncomplicated, and the patient was successfully discharged. The plasma renin activity was maintained at a high level even after left nephrectomy, suggesting that the right kidney was likely the source of renin secretion. Mechanical compression of the right renal blood vessels by a greatly enlarged left kidney can cause right renal ischemia, which activates renin excretion. Nephrectomy can be an effective treatment for a WT patient with hypertension causing hypertensive cardiomyopathy, and then cardiac function will be improved within several weeks. We recommend routine echocardiography surveillance in patients with WT. This report can help pediatric surgeons become more familiar with cardiomyopathy caused by WT.
