BACKGROUND Laparoscopic colorectal surgery remains one of the most challenging techniques to learn. METHODS The authors collected studies that have compared hand-assisted laparoscopic surgery (HALS) and open surgery for the treatment of colorectal disease over the past 17 years. Data of interest for HALS and open surgery were subjected to meta-analysis. RESULTS Twelve studies that included ...

PURPOSE The laparoscopic colectomy is avoided principally because of its technical difficulty, steep learning curve, and increased operative time. Hand-assisted laparoscopic surgery (HALS) is an alternative technique that addresses these problems while preserving the short-term benefits of a laparoscopic colectomy. Our study was aimed to describe the characteristics of patients admitted due to ...

OBJECTIVE The objective of this study is to systematically assess the clinical efficacy of hand-assisted laparoscopic surgery (HALS) and laparoscopic right colectomy (LRC). METHODS The randomized controlled trials (RCTs) and non-RCTs were collected by searching electronic databases (Pubmed, Embase, and the Cochrane Library). The outcomes included intraoperative outcomes, postoperative outcome...

PURPOSE To compare and assess the efficacy, safety and utility of hand-assisted laparoscopic surgery (HALS) with open surgery (OS) in total colectomy with ileorectal for colonic inertia. METHODS From January 2001 to February 2012, 56 patients diagnosed with colonic inertia who failed to respond to medical treatments underwent hand-assisted laparoscopic total colectomy with ileorectal anastomo...

Iodine containing disinfection by-products (I-DBPs) and haloacetaldehydes (HALs) are emerging disinfection by-product (DBP) classes of concern. The former due to its increased potential toxicity and the latter because it was found to be the third most relevant DBP class in mass in a U.S. nationwide drinking water study. These DBP classes have been scarcely investigated, and this work was perfor...

Non-negative tensor factorization (NTF) has been successfully applied to analyze event-related potentials (ERPs), and shown superiority in terms of capturing multi-domain features. However, the time-frequency representation of ERPs by higher-order tensors are usually large-scale, which prevents the popularity of most tensor factorization algorithms. To overcome this issue, we introduce a non-ne...

BACKGROUND Hand assist laparoscopy (HALS) is a minimally invasive technique which allows for the placement of the surgeon's non-dominant hand through a hand-port device while maintaining pneumoperitoneum. There is no standardization of this procedure and it is rarely used in gynecology. METHODS The multidisciplinary team of authors, with experience in minimally invasive pelvic surgery, has de...

Minimally invasive laparoscopic surgery has become widespread and the indications for such surgery have recently been extended to various conditions, including rectal cancer. The objective of this study was to compare the clinical outcome of hand-assisted laparoscopic surgery (HALS) and conventional laparotomy (CL) in patients with rectal cancer. Patients who underwent radical resection of stag...

Polymeric hindered amine light stabilizers (polymeric HALS) have been extensively studied because they combine a high ability to protect the polymers against harmful effects of weathering with minimum physical loss. In this study a new polymeric N-methylated HALS was synthesized by the radical copolymerization of a cyclic tertiary amine with vinyl acetate (VAc). 4-Acryloyloxy-1,2,2,6,6-pentamet...

Objective: To compare the treatment outcomes of hand-assisted laparoscopic surgery (HALS) versus laparoscopic-assisted surgery (LAS) in radical gastrectomy for advanced distal gastric cancer. Methods: The prospective randomized control study was carried out to compare the short-term and long-term outcomes of the 124 patients who underwent radical treatment for advanced distal gastric cancer fro...
