Foot venous pressure measurements showed a good correlation with clinical severity and degree of venous reflux and were very useful for evaluating the outcome of therapy for venous insufficiency.
Objective:This study aimed to determine whether retrocolic alimentary tract reconstruction is noninferior to antecolic reconstruction in terms of DGE incidence after pancreatoduodenectomy (PD) and investigated patients’ postoperative nutritional status.Summary of Background Data:The influence of the route of alimentary tract reconstruction on DGE after PD is controversial.Methods:Patients from 9 participating institutions scheduled for PD were randomly allocated to the retrocolic or antecolic reconstruction groups. The primary outcome was incidence of DGE, defined according to the 2007 version of the International Study Group for Pancreatic Surgery definition. Noninferiority would be indicated if the incidence of DGE in the retrocolic group did not exceed that in the antecolic group by a margin of 10%. Patients’ postoperative nutrition data were compared as secondary outcomes.Results:Total, 109 and 103 patients were allocated to the retrocolic and antecolic reconstruction group, respectively (n = 212). Baseline characteristics were similar between both groups. DGE occurred in 17 (15.6%) and 13 (12.6%) patients in the retrocolic and antecolic group, respectively (risk difference; 2.97%, 95% confidence interval; −6.3% to 12.6%, which exceeded the specified margin of 10%). There were no differences in the incidence of other postoperative complications and in the duration of hospitalization. Postoperative nutritional indices were similar between both groups.Conclusions:This trial could not demonstrate the noninferiority of retrocolic to antecolic alimentary tract reconstruction in terms of DGE incidence. The alimentary tract should not be reconstructed via the retrocolic route after PD, to prevent DGE.
FVP parameters correlate well with the severity of clinical manifestations and venous reflux, and could be used quantitatively to evaluate the severity of CVI.
An 80-year-old woman with a pleomorphic carcinoma (PC) producing hCG was admitted to Nippon Steel Hirohata Hospital because of an abnormal shadow on CT seen during a follow-up examination after surgery for breast cancer. A right upper lobectomy was performed due to rapid growth of the shadow 3 months later. Macroscopically the tumor was a 4.8 x 4.0 cm well-circumscribed grayish-white mass. On histology the tumor consisted mostly of intermingled spindle and polygonal cells, while evidence of poorly differentiated adenocarcinoma was seen in a few areas. A diagnosis of PC was made due to hCG expression in approximately 20% of the spindle and polygonal cells on immunohistology. Six months after the operation metastasis to the liver and adrenal gland was seen on CT. The patient died due to metastases 1 year after the operation, even though the patient had been at stage 1B at the time of the operation and appropriate chemotherapy had been given. PC patients with immunohistochemical hCG expression have elevated risk of local recurrence and metastasis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
