BACKGROUND Although conventional laparoscopic and hand-assisted laparoscopic surgery for colorectal cancer is widely used today, there remain many technical challenges especially for right colon cancer in obese patients. Herein, we develop a novel hand-assisted laparoscopic surgery (HALS) with complete mesocolic excision (CME), D3 lymphadenectomy, and a total "no-touch" isolation technique (HAL...
HYPOTHESIS Laparoscopic splenectomy (LS) is the procedure of choice for elective splenectomy. Splenomegaly may preclude safe mobilization and hilar control using conventional laparoscopic techniques. Hand-assisted LS (HALS) may offer the same benefits of minimally invasive surgery for splenomegaly while allowing safe manipulation and splenic dissection. DESIGN A retrospective review of patien...
BACKGROUND Uridine has been advocated for the treatment of HIV-1/HAART-associated lipodystrophy (HALS), although its metabolism in HIV-1-infected patients is poorly understood. METHODS Plasma uridine concentrations were measured in 35 controls and 221 HIV-1-infected patients and fat uridine in 15 controls and 19 patients. The diagnosis of HALS was performed following the criteria of the Lipod...
Nonnegative Matrix Factorization (NMF) is a data analysis technique which allows compression and interpretation of nonnegative data. NMF became widely studied after the publication of the seminal paper by Lee and Seung (Learning the Parts of Objects by Nonnegative Matrix Factorization, Nature, 1999, vol. 401, pp. 788–791), which introduced an algorithm based on Multiplicative Updates (MU). More...
Background: This study aims to comparative treatment outcomes of hand-assisted laparoscopic surgery (HALS) versus open surgery (OS) in radical gastrectomy of advanced distal gastric cancer. Methods: This was a prospective randomized controlled study of 124 patients who underwent radical treatment for advanced distal gastric cancer from May 2008 and April 2012. Among them, the patients were divi...
Objective: This retrospective study aims to compare the clinical outcomes between conventional laparotomy and hand-assisted laparoscopic surgery (HALS) with D3 lymph node dissection in the treatment of right colon cancer and to analyze and evaluate the feasibility and safety of HALS with D3 lymph node dissection. Methods: Among 63 patients, 35 underwent HALS with D3 lymph node dissection (study...
INTRODUCTION Minimally invasive surgery has revolutionized general surgery during the past 10 years. However, for more advanced surgical procedures, the acceptance of the minimally invasive approach has been slower than expected. Advanced laparoscopic surgery is complex and time-consuming. The major drawbacks of laparoscopic surgery are two-dimensional view, lack of depth perception and loss of...
