Uniportal video-assisted thoracic surgery (VATS) lung wedge resection usually requires three devices, thoracoscope, lung retracting instrument and an endo-stapler cutter to perform the procedure. With advances in miniaturization of the thoracoscope and lung retracting instruments, a major limitation to operating through a smaller uniportal incision has become the endo-stapler. We describe the surgical technique for uniportal VATS laser lung resection which uses a much narrower laser catheter device to replace the endo-stapler for resection...

BACKGROUND: Formation of clots in the left atrial appendage (LAA) may lead to embolism and consecutive cerebral stroke. This risk is reduced by closure and resection. To address the efficacy of surgical LAA closure, resilience to pneumatic pressure was studied. Different surgical techniques were compared in an experimental model. METHODS: From freshly slaughtered pigs cardiopulmonary preparations were taken. The left atrium was clamped airtight and the LAA was cannulated...

BACKGROUND: Esophageal reconstruction after esophagectomy is a complex procedure with high morbidity and mortality. Anastomotic leakage is more severe and frequent in patients with preoperative comorbidities and may present with septic conditions. Considering the possibility of an easier management of such cases, we evaluated the safety and feasibility of subcutaneous esophageal reconstruction in patients with high operative risks. METHODS: We performed a non-randomized retrospective observational study on the 75 (subcutaneous: 21, intrathoracic: 54) esophageal cancer patients who underwent esophageal reconstruction either through subcutaneous or intrathoracic route between January 2003 and February 2015...

BACKGROUND: Lung Cancer is a primary tumor with poor prognosis. For early stage lung cancer, treatment options include surgical resection and microwave techniques. Percutaneous ablative techniques emerged as best therapeutic options for nonsurgical patients. METHODS: The aim of this study was to retrospectively analyze the clinical effect of CT-guided microwave ablation (MWA) treatment for patients with lung cancer who were not eligible for surgical resection. MWA was used to treat the tumor lesion of 113 patients with lung cancer who were in our hospital from Jan, 2013 to Jun, 2015...

Robotically guided knee arthroplasty systems generally require an individualized, preoperative 3D model of the knee joint. This is typically measured using Computed Tomography (CT) which provides the required accuracy for preoperative surgical intervention planning. Ultrasound imaging presents an attractive alternative to CT, allowing for reductions in cost and the elimination of doses of ionizing radiation, whilst maintaining the accuracy of the 3D model reconstruction of the joint. Traditional phased array ultrasound imaging methods, however, are susceptible to poor resolution and signal to noise ratios (SNR)...

Osteogenesis imperfecta (OI) is a rare disabling genetic connective tissue disorder. General anesthesia in these patients is associated with increased risks. Regional anesthesia is favored wherever feasible, but there are limited reports of use of a sole regional technique in OI in pediatric patients. Moreover, combined spinal-epidural anesthesia has never been described previously. We are reporting the use of combined spinal-epidural anesthesia for a prolonged surgery (multiple osteotomies) of lower limbs in a 10-year-old wheelchair-bound child with OI type III...

Humaid Ahmad, Sheeraz Shakoor Siddiqui
Skin carbuncles are debilitating skin infections commonly seen in elderly patients with diabetes. These infections develop when a cluster of adjacent furuncles coalesce to form one inflammatory mass. While they commonly occur on the nape of the neck and back, rarer sites involving the face and head have been noted. Management of these rare sites is urgent because of the potential intracranial complications and the surgical outcome is often unsatisfactory due to associated facial scarring. Intraoral drainage is advocated to avoid this; however, when the carbuncle involves a larger area, debridement from the exterior is necessary...

BACKGROUND: Surgical site infections (SSIs) are one of the most common hospital-acquired infections. To reduce SSIs, prophylactic intra-operative wound irrigation (pIOWI) has been advocated, although the results to date are equivocal. To develop recommendations for the new World Health Organization (WHO) SSI prevention guidelines, a systematic literature review and a meta-analysis were conducted on the effectiveness of pIOWI using different agents as a means of reducing SSI. METHODS: The PUBMED, Embase, CENTRAL, CINAHL, and WHO databases were searched...

In the study of adult stem cells and regenerative mechanisms, planarian flatworms are a staple in vivo model system. This is due in large part to their abundant pluripotent stem cell population and ability to regenerate all cell and tissue types after injuries that would be catastrophic for most animals. Recently, planarians have gained popularity as a model for eye regeneration. Their ability to regenerate the entire eye (comprised of two tissue types: pigment cells and photoreceptors) allows for the dissection of the mechanisms regulating visual system regeneration...

Accessory respiratory muscles help to maintain ventilation when diaphragm function is impaired. The following protocol describes a method for repeated measurements over weeks or months of accessory respiratory muscle activity while simultaneously measuring ventilation in a non-anesthetized, freely behaving mouse. The technique includes the surgical implantation of a radio transmitter and the insertion of electrode leads into the scalene and trapezius muscles to measure the electromyogram activity of these inspiratory muscles...

BACKGROUND: Uterine fibroids are the commonest benign tumor of the female genital tract. They affect a significant proportion of reproductive aged women and may cause excessive menstrual bleeding, pelvic pain or pressure, and adversely affect reproductive outcomes. However, many women remain asymptomatic. Fibroids are the first indication for hysterectomy, but myomectomy is the most suitable surgical option for women who desire preservation of their fertility potential. Only a selected group of women of childbearing age will benefit from a myomectomy, as the consequences of myomectomy on reproductive function have remained controversial...

The altered anatomy in patients after bariatric surgery who have undergone a Roux-en-Y gastric bypass may pose a technical challenge for surgical removal of the pancreatic head. We treat patients with pancreas cancer with multimodality therapy in a neoadjuvant fashion followed by pancreaticoduodenectomy (PD). In patients with Roux-en-Y gastric bypass anatomy, the gastric remnant is preserved and used for pancreaticogastrostomy reconstruction and subsequently drained by the same jejunal limb used for the hepaticojejunostomy...

BACKGROUND: Performing a safe esophagojejunostomy is important for the standardization of laparoscopic total gastrectomy. We have performed intracorporeal esophagojejunostomy by a circular stapler using the purse-string suturing device that we co-developed. The advantage of this device is that it makes use of the same surgical procedure as open surgery, but it does not depend on the surgeon's technical skills since this device does not require the laparoscopic hand-sewn technique. Furthermore, we have also adapted this device for double-tract reconstruction after laparoscopic proximal gastrectomy...
