BACKGROUND Multiple techniques for splenectomy are now employed and include open, laparoscopic and hand-assisted laparoscopic splenectomy (HALS). Concerns regarding a purely laparoscopic splenectomy for massive splenomegaly (> 20 cm) arise from potentially longer operative times, higher conversion rates and increased blood loss. The HALS technique offers the potential advantages of laparoscopy,...

HYPOTHESIS Hand-assisted laparoscopic surgery (HALS) is a safe therapeutic approach to remove megaspleens of any size. Conventional laparoscopic splenectomy for splenomegaly is difficult because of limited exposure and complex vascular control, with increased risk of intraoperative bleeding and conversion to open surgery. HALS can overcome some of these limitations, reducing the risk of convers...

BACKGROUND Laparoscopic splenectomy (LS) has several advantages over the open procedure but can be technically demanding when performed in patients with massive splenomegaly. We hypothesized that patients who undergo hand-assisted LS (HALS) may experience the benefits of LS while having their enlarged spleens removed safely. METHODS We reviewed the charts of patients who underwent HALS or LS ...

OBJECTIVE Hand assist laparoscopic surgery (HALS) is a surgical modality rarely used in benign gynecology. We analyzed nonmalignant pelvic disorders that utilized HALS to see whether there is any benefit over standard laparotomy. METHODS A case control chart review identified patients who underwent HALS for a variety of benign gynecological conditions from 2004 through 2007. Cases were then c...

BACKGROUND This study was designed to compare the long-term surgical outcomes of patients with mid and low rectal cancer after open or hand-assisted laparoscopic surgery (HALS). METHODS A case-matched controlled prospective analysis of 116 patients who underwent hand-assisted laparoscopic surgery (HALS) for stage I to III mid and low rectal cancer from 2005 to 2010 was performed. Contemporary...

PURPOSE Hand-assisted laparoscopic surgery (HALS) is a minimally invasive surgical technique with the combined benefits of laparoscopic surgery while allowing the use of the surgeon's hand for better tactile control. Obesity has been associated with higher conversion rates with multiport laparoscopic surgery, but not with HALS. This study aimed to examine the versatility of HALS in various clin...

own advantages [2-4]. The authors compared a HALS right hemicolectomy with an open right hemicolectomy. In common with many other reports in the literature, they found the HALS technique to be equal to or better than open surgery with respect to postoperative clinical parameters [5, 6]. Among the several advantages of HALS, the authors particularly emphasized restoration of tactile feedback to ...

PURPOSE To assess in a cohort of Caucasian patients exposed to stavudine (d4T) the association of polymorphisms in pyrimidine pathway enzymes and HLA-B*40∶01 carriage with HIV/Highly active antiretroviral therapy (HAART)-associated lipodystrophy syndrome (HALS). METHODS Three-hundred and thirty-six patients, 187 with HALS and 149 without HALS, and 72 uninfected subjects were recruited. The di...

Colorectal surgeons have many options for minimally invasive surgery (MIS), including standard laparoscopic surgery (SLS), single-port surgery, robotic surgery, a transanal total mesorectal excision (TME), and hand-assisted laparoscopic surgery (HALS). Traditionally, SLS is the most common type of MIS. However, nowadays, MIS using small incisions, for example, single-port surgery and transanal ...

Abstract To clarify the effect of Hindered amine light stabilizer (HALS) on ultraviolet (UV) aging behavior asphalt binder, evolution history and characteristics UV induced micro-structure modified were characterized. Scanning Electron Microscope (SEM) Atomic Force (AFM) used to analyze microscopic morphology stabilizer-modified during aging. By defining in joints by UV, identification classifi...
