BACKGROUND: Laparoscopic surgery for gastric tumor is considered a demanding procedure because of lymph node dissection and reconstruction. Billroth-I (B-I) reconstruction after laparoscopic distal gastrectomy is commonly performed extracorporeally because of the complexity of an intracorporeal procedure. Robotic surgery overcomes some limitations of laparoscopy, allowing to reproduce the basic maneuvers of open surgery. We describe a new technique to perform robotic B-I anastomosis. METHODS: Between January 2012 and February 2015, 5 patients underwent distal gastrectomy with intracorporeal B-I-stapled anastomosis...

Zhencheng Fan, Guowen Chen, Junchen Wang, Hongen Liao
We develop a spatial position measurement system using three-dimensional (3-D) image marker-based tracking tools targeted at surgical navigation in minimally invasive surgery. We generate 3-D image markers with spatial information encoded to 2-D images, design tracking tools with the 3-D image markers, and analyze the tracking tools' theoretical spatial errors, which are primarily limited by the spatial distribution of reconstructed fiducial 3-D markers. A pattern analysis-based positional measurement algorithm is developed to calculate the tool's spatial information using its spatial configuration...

BACKGROUND: Peripheral arterial disease (PAD) is a complex and highly prevalent pathology. It has been estimated that ∼8.5 million people in the United States are affected by PAD, of which 12%-20% are older than age 60. The TransAtlantic Inter-Society Consensus (TASC) guidelines classified aortoiliac atherosclerotic disease based on morphology and level of lesions. TASC II guidelines recommend bilateral surgical bypass to the femoral arteries for TASC II C and D lesions. The aortobifemoral bypass (ABF) has been considered the gold standard in the treatment of aortoiliac occlusive disease (AIOD)...

This single-centre, prospective trial was designed to assess the efficacy of a new retrograde transillumination device called the 'Infrared Red Intubation System' (IRRIS) to aid videolaryngoscopic tracheal intubation. We included 40 adult patients, who were undergoing elective urological surgery under general anaesthesia. We assessed the ability to differentiate the transilluminated glottis from other structures and found a median (IQR [range]) larynx recognition time of 8 (5-14 [3-28]) s. The difference in laryngeal visibility on the screen between the deactivated vs...

BACKGROUND: Intersphincter resection (ISR) is considered to be a superior technique offering sphincter preservation in patients with ultralow rectal cancer.1 Because high-definition laparoscopy offers wider and clearer vision into the narrow pelvic cavity and intersphincteric space, ISR has been further refined.2 However, functional outcome after ISR has not been optimal. More than half of patients receiving ISR suffer partial or even complete anal incontinence.3 We therefore propose a laparoscopic-assisted modified ISR, with the aim of improving sphincter function following ISR...

BACKGROUND: Ureteral stents are commonly placed before colorectal resection to assist in identification of ureters and prevent injury. Acute kidney injury (AKI) is a common cause of morbidity and increased cost following colorectal surgery. Although previously associated with reflex anuria, prophylactic stents have not been found to increase AKI. We sought to determine the impact of ureteral stents on the incidence of AKI following colorectal surgery. METHODS: All patients undergoing colon or rectal resection at a single institution between 2005 and 2015 were reviewed using American College of Surgeons National Surgical Quality Improvement Program dataset...

Avoidance of red blood cell (RBC) transfusions in patients awaiting heart transplantation (HTx) has been suggested to minimize the risk of allosensitization. Although recent studies have suggested that an immature immune system in younger HTx recipients may reduce risks associated with RBC transfusion, the role of age in moderating the influence of transfusion on HTx outcomes remains unclear. We used available data from a national transplant registry to explore whether the association between pre-transplant transfusions and outcomes of pediatric HTx varies by patient age...
