PURPOSE: Two-stage minimally invasive esophagectomy (MIE) has gained popularity in the surgical treatment of esophageal cancer. MIE's limitation is embedded in the construction of intrathoracic anastomosis. Various anastomotic techniques have been reported; however, the mechanical one remains the most commonly adopted. This pilot study aims to describe an efficient, safe, and reproducible way of performing a hand-sewn intrathoracic esophagogastric anastomosis in conjunction with short-term results using 2D and 3D thoracoscopic approaches...

BACKGROUND: Colorectal cancer is common in humans where treatment involves surgical removal of the cancerous part of the intestines. In the anastomosis procedure a purse-string suture may be time consuming to perform. The aim was to replace the purse-string suture, to develop and test a self-locking loop for temporary sealing of the lumen in colon anastomosis. METHODS: A new device, a flexible band with a locking mechanism was constructed, the I-Tie(®). Small protrusions, designed for increased friction between device and tissue, were added to one side of the flexible band in order to enhance the grip at closure of the loop around tissue...

INTRODUCTION: A realistic hemorrhagic cervical cancer model was three-dimensionally (3D) printed and used in a postgraduate medical simulation training session. MATERIALS AND METHODS: Computer-assisted design (CAD) software was the platform of choice to create and refine the cervical model. Once the prototype was finalized, another software allowed for the addition of a neoplastic mass, which included openings for bleeding from the neoplasm and cervical os. 3D printing was done using two desktop printers and three different materials...

BACKGROUND: Among all procedures, surgical site infections (SSIs) in colorectal surgery continue to have the highest rate, accounting for 5%-45%. To prevent the bacterial colonization of suture material, which disables local mechanisms of wound decontamination, triclosan-coated sutures were developed. We assessed the effectiveness of triclosan-coated sutures used for skin closure on the rate of SSIs in colorectal cancer surgery. METHODS: Until August 2012, we used conventional methods for skin closure in colorectal cancer surgery at the Department of Gastroenterological Surgery, Fukuoka University Faculty of Medicine...

The transcription factor Twist is an important regulator of cranial suture during embryogenesis. Closure of the neural tube is achieved via Twist-triggered cellular transition from an epithelial to mesenchymal phenotype, a process known as epithelial-mesenchymal transition (EMT), characterized by a remarkable increase in cell motility. In the absence of Twist activity, EMT and associated phenotypic changes in cell morphology and motility can also be induced, albeit moderately, by other transcription factor families, including Snail and Zeb...

BACKGROUND AND OBJECTIVES: Laparoscopic anastomotic methods are not commonly used because of the cumbersome laparoscopic intracorporeal sutures and tying involved. The barbed suture is one of the various devices developed to simplify the placement of intracorporeal sutures. However, barbed sutures are not commonly used during reconstruction after radical gastrectomy in cancer patients or for single-layer entire-thickness running suturing for intestinal anastomoses. We describe the procedure for using barbed sutures and report on the short-term surgical outcomes...

INTRODUCTION: Laparoscopic surgery is widely used for the treatment of colorectal cancer, but it is often associated with postoperative anastomotic complications. Generally, gastrointestinal anastomosis for colorectal surgery is performed using mechanical anastomosis with a double stapling technique. Using the automatic suture device with bioabsorbable polyglycolic acid (PGA) felt is expected to adequately reinforce staple lines on fragile tissue, helping to prevent anastomotic complications, including leakage...

Lung cancer invading pulmonary trunk is a locally advanced condition, which may indicate poor prognosis. Surgical resection of the lesion can significantly improve survival for some patients. Lobectomy/Pneumonectomy with pulmonary arterioplasty via thoracotomy were generally accepted and used in the past. As the rapid development of minimally invasive techniques and devices, pulmonary arterioplasty is feasible via video-assisted thoracic surgery (VATS). However, few studies have reported the VATS surgical techniques...

Lung cancer invading the superior vena cava (SVC) is a locally advanced condition, for which poor prognosis is expected with conservative treatment alone. Surgical resection of the lesion can rapidly relieve the symptoms and significantly improve survival for some patients. Replacement, repair and partial resection of SVC via thoracotomy were generally accepted and used in the past. As the rapid development of minimally invasive techniques and devices, partial resection and repair of SVC are feasible via video-assisted thoracic surgery (VATS)...

OBJECTIVES: To evaluate the feasibility of robot-assisted laparoscopic high-intensity focused ultrasound for targeted, extravesical, transmural, full-thickness ablation of intact bladder wall and tumor. METHODS: In three fresh cadavers and one acute porcine model, the transperitoneal robotic approach was used to mobilize the bladder and create a midline cystotomy. "Mimic" bladder tumors (2 tumors/case) were created by robotically suturing a piece of striated muscle (2...

Catheterization of the intestinal lymph trunk in neonatal pigs is a technique allowing for the long-term collection of large quantities of intestinal (central) efferent lymph. Importantly, the collection of central lymph from the intestine enables researchers to study both the mechanisms and lipid constitutes associated with lipid metabolism, intestinal inflammation and cancer metastasis, as well as cells involved in immune function and immunosurveillance. A ventral mid-line surgical approach permits excellent surgical exposure to the cranial abdomen and relatively easy access to the intestinal lymph trunk vessel that lies near the pancreas and the right ventral segment of the portal vein underneath the visceral aspect of the right liver lobe...

BACKGROUND: Totally laparoscopic distal gastrectomy (TLDG) using intracorporeal anastomosis has gradually developed due to advancements in laparoscopic surgical instruments. However, totally laparoscopic total gastrectomy (TLTG) with intracorporeal esophagojejunostomy (IE) is still uncommon because of technical difficulties. Herein, we evaluated various types of IE after TLTG in terms of the technical aspects. We compared the short-term operative outcomes between TLTG with IE and laparoscopy-assisted total gastrectomy (LATG) with extracorporeal esophagojejunostomy (EE)...

Prior to the 20(th) century, the need for surgical procedures on the airway was infrequent and consisted mainly of tracheostomy to relieve airway obstruction or repair of tracheal injuries such as lacerations. Even the ability of tracheal suture lines to heal primarily was viewed with concern due to the rigidity of the tracheal wall, its precarious blood supply and uncertainty as to whether the cartilage components could heal without complications. In the 20(th) century the evolution of tracheal procedures on major airways evolved to meet the challenges provided by the expanding fields of thoracic surgery and advent of mechanical respiratory support with its associated complications...

BACKGROUND: The introduction of the minimally invasive approach changed the way abdominal surgery was carried out. Open suture and mesh reinforcement in ventral hernia repair used to be the surgeon's choice of procedure. Although the laparoscopic approach, with defect bridging and mesh fixation, has been described since 1993, the procedure remains largely unchanged. Evidence shows that defect closure and retro-muscular mesh positioning have the best outcomes and are the best surgical practice...

We present a new gaze tracking-based navigation scheme for proton beam radiation of intraocular tumors and we show the technical integration into the treatment facility. Currently, to treat a patient with such a tumor, a medical physicist positions the patient and the affected eye ball such that the radiation beam targets the tumor. This iterative eye positioning mechanism requires multiple X-rays, and radio-opaque clips previously sutured on the target eyeball. We investigate a possibility to replace this procedure with a noninvasive approach using a 3-D model-based gaze tracker...

Damage of the lymphatic vessels, commonly due to surgical resection for cancer treatment, leads to secondary lymphedema. Tissue engineering approach offers a possible solution to reconstruct this damage with the use of lymphatic graft to re-establish the lymphatic flow, hence preventing lymphedema. The aim of this study is to develop a tissue-engineered lymphatic graft using nanocomposite polymer and human dermal lymphatic endothelial cells (HDLECs). A nanocomposite polymer, the polyhedral oligomeric silsequioxane-poly(carbonate-urea)urethane (POSS-PCU), which has enhanced mechanical, chemical, and physical characteristics, was used to develop the lymphatic graft...

UNLABELLED: Anterior resection for rectal cancer carries the risk of serious complications, especially fistulas at the site of anastomosis. Numerous factors have been shown to impact anastomotic leakage. The results of studies on the influence of obesity on the frequency of anastomotic leakage after rectal resection performed due to cancer have been contradictory. The aim of the study was to evaluate the relationship between body mass index (BMI) and frequency of anastomotic leakage after anterior rectal resection performed due to cancer...
