Lumboaortic and iliac lymphadenectomy: what is the role today?
No full textPURPOSE:
The aim of this study was to evaluate the roles of the lymphadenectomy in the surgical treatment of rectal cancer.
METHODS:
On the basis of our experience of 252 curative operations for rectal cancer, we analyze survival and recurrence in relation to the lymph node involvement and to the level of the lymph nodes where the metastases are located. All patients underwent a lymphadenectomy with high ligation of the inferior mesenteric artery and removal of the lumboaortic lymph nodes from the left renal vein to the aortic bifurcation. Pelvic lymphadenectomy was performed in 16 cases.
RESULTS:
Five-year survival was 70.6 percent in patients with no lymph node involvement, 68.2 percent in patients with pararectal lymph nodes N+, 25 percent in patients with involvement of intermediate lymph nodes, and 30 percent in patients with involvement of lumboaortic lymph nodes. In no case was there involvement of the hypogastric lymph nodes. On the basis of our experience and from results in the literature, we consider an upward extended lymphadenectomy with high ligation of the inferior mesenteric artery is warranted since it enables the tumor to be staged accurately and may lead to survival even in cases of advanced lymph node involvement
Four-year outcomes of intragastric balloon for morbid obesity: a retrospective study.
No full textThe intragastric balloon is a safe procedure inducing weight loss in selected obese patients, especially for those who are not suitable for bariatric surgery. The balloon can play a role in the preoperative treatment of obese patients who will undergo elective surgery, by lowering mortality and morbidity risks
Six-Year outcomes of Laparoscopic Adjustable Gastric Banding, Laparoscopic Gastric Bypass and Sleeve Gastrectomy: a retrospective study.
No full textPresentation of the 6-year follow-up after laparoscopic gastric bypass, laparoscopic adjustable gastric banding and sleeve gastrectomy. The study suggests a superior weight loss and improvement in obesity-associated complications for the laparoscopic gastric bypass. The laparoscopic adjustable gastric banding is effective if patient selection is done by a multidisciplinary team
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
