A mucocele is the most common minor salivary gland disease and among the most common biopsied oral lesions in pediatric patients. Clinically, a mucocele appears as a round well-circumscribed painless swelling ranging from deep blue to mucosa alike in color. Mucoceles rarely resolve on their own and surgical removal under local anesthesia is required in most cases. Different treatment options are described in the literature, including cryosurgery, intra-lesion injection of corticosteroid, micro-marsupialization and conventional surgical removal using a scalpel, and laser ablation...

REVIEW
Taufiek Konrad Rajab
The first lung transplantation in the rat was achieved by Asimacopoulos et al using sutured anastomoses in 1971. Subsequent development of a cuffed technique to construct the anastomoses by Mizuta and colleagues in 1989 represented a breakthrough that resulted in simplification of the procedure and shorter warm ischemic times. Since then, a number of further variations on the technique of rat lung transplantation have been described. In spite of this, the procedure remains technically demanding and involves a long learning curve...

Systemic inflammatory response and hemodilution are prominent factors associated with cardiopulmonary bypass and result in increased morbidity and mortality in children. Miniaturized systems have evolved in order to decrease such effects and restrict use of blood products, especially in the neonatal population. We have developed a table mounted cardiopulmonary bypass system that allows closer proximity of the system to the patient with consequent decrease in priming volumes, hemodilution, its associated effects and contributes to the development into an ideally bloodless surgical approach...

BACKGROUND: Although bloodless cardiac surgery has been successfully performed for many years, studies with controls permitting transfusion are few and their results inconclusive. This study compares the outcome of cardiac surgery on Jehovah's Witnesses (JW) refusing transfusion, with that of controls permitting transfusion if required. METHODS: Data from 172 operations in 162 JW were compared with 172 matched controls. Risk factors, preoperative, operative, 48 hour postoperative variables, outcome data and transfusions were recorded...

Introduction Laparoscopic cholecystectomy (LC) is the most commonly done, minimally invasive surgical procedure. Routinely used electrocautery produces more smoke, which masks the operating field, thereby prolongs the surgery and posing an increased risk of gallbladder (GB) perforation. The titanium clips used for clipping the cystic artery and cystic duct have a risk of slippage, which may lead to bleeding, and an increased risk for bile leakage. In addition, it may act as a nidus for stone formation. Advanced energy sources, such as the harmonic scalpel, though expensive, may provide the advantage of shorter operating time by reducing smoke, bloodless dissection in the GB bed, lower risk of bleeding from the cystic artery due to secure vessel sealing, and avoiding the use of a larger number of titanium clips...

Introduction: Cataract surgery has undergone various advances since it was evolved from ancient couching to the modern phacoemulsification cataract surgery. Surgically induced astigmatism (SIA) remains one of the most common complications. The introduction of sutureless clear corneal incision has gained increasing popularity worldwide because it offers several advantages over the traditional sutured limbal incision and scleral tunnel. A clear corneal incision has the benefit of being bloodless and having an easy approach, but SIA is still a concern...

Achieving pediatric cardiac surgery using cardiopulmonary bypass (CPB) without allogeneic blood transfusion is challenging. There are many clinical and economic factors that point to the importance of avoiding blood transfusions. In some instances, honoring patients or parents beliefs may be the reason for avoiding blood transfusions. For example, patients or parents of the Jehovah's Witness faith refuse blood transfusion based on their religious beliefs. Over the last decade, our institution has seen a steady increase in our pediatric Jehovah's Witness patient population...

A contribution of pulmonary blood distension to alveolar opening was first proposed more than 100 years ago. To investigate the contribution of blood distension to lung mechanics, we studied control mice (normal perfusion), mice after exsanguination (absent perfusion) and mice after varying degrees of parenchymal resection (supra-normal perfusion). On inflation, mean tracheal pressures were higher in the bloodless mouse (4.0 ± 2.5 cm H2 O); however, there was minimal difference between conditions on deflation (0...

We describe a novel patient position for endoscopic transphenoidal surgery - the 'conversational position'. This position is a safe and effective alternative to the standard supine position, incorporating a semi-sitting position with the additional innovation of achieving a 'conversational position' by flexing the neck and turning the patient's head turned to face the surgeon. The 'conversational' position offers improvements in the surgical approach to sellar region, addressing specific intraoperative challenges such as maintaining a bloodless operative field, and enabling more intuitive and ergonomic surgical workflow...

According to expansion of dialysis-dependent population, more than half of patients with critical ischemic limbs are dialysis-dependent in Japan. Although patients with end-staged renal disease are well-known as poor life prognosis, well-managed dialysis patients in Japan can survive much longer compared to dialysis patients in the United States and Europe. Therefore, some dialysis patients can enjoy the long-term benefits of bypass surgery. To decide the indication of bypass surgery, patient's general condition, nutrition status, and vein availability are more important rather than arterial disease anatomy...

PURPOSE: Minor hand surgeries can be done under field sterility in procedure rooms. Surgeons are still sceptical about the usage of wide awake local anaesthesia no tourniquet (WALANT) technique. They perceive that patients can tolerate tourniquet for a brief period while they perform minor surgeries under local anaesthesia (LA). We compared the perceived comfort experienced by patients during minor hand surgeries with WALANT and LA/tourniquet. We investigated the difference in preoperative preparation time, operating time and blood loss between the two groups...

BACKGROUND: Cardiac surgery on Jehovah's Witnesses (JW) can be challenging, given the desire to avoid blood products. Establishment of a blood conservation program involving the pre-, intra- and post-operative stages for all patients may lead to a minimized need for blood transfusion in all patients. METHODS: Pre-operatively, all JW patients were treated with high dose erythropoietin 500 IU/kg twice a week. JW patients were compared to matching non-JW patients from the congenital cardiac database, two per JW to serve as control...

Various methods for surgical repair of the aortic arch are described throughout the literature with many focused on cannulation techniques and degree of systemic cooling in an effort to reduce postoperative morbidities. Despite advancements in techniques, this surgery is still often associated with higher levels of blood loss and subsequent allogenic blood transfusions. Although blood products can be safely transfused to the majority of patients undergoing repair of the aortic arch, the complexity and risk is further multiplied when the patient is of Jehovah's Witness faith and refuses blood transfusions...

REVIEW
Manjula Sarkar, Vishal Prabhu
Cardiopulmonary bypass (CPB) provides a bloodless field for cardiac surgery. It incorporates an extracorporeal circuit to provide physiological support in which venous blood is drained to a reservoir, oxygenated and sent back to the body using a pump. Team effort between surgeon, perfusionist and anaesthesiologist is paramount for the successful use of CPB. However, it also has its share of complications and strategies to reduce these complications are the area of the current research.

Invasion of a renal cell carcinoma thrombus into the inferior vena cava and right atrium is infrequent. Reaching and completely excising a tumor from the inferior vena cava is particularly challenging because the liver covers the surgical field. We report the case of a 61-year-old man who underwent surgery for a renal cell carcinoma of the right kidney that extended into the inferior vena cava and right atrium. During dissection of the liver to expose the inferior vena cava, transesophageal echocardiograms revealed right atrial mass migration into the tricuspid valve...
