BACKGROUND/AIMS A retained foreign body in the abdominal cavity following surgery is a continuing problem. Despite precautions, the incidence is grossly underestimated. The purpose of this study is to report the result of surgical treatment on 24 consecutive cases treated by the authors during a 10-year period. METHODOLOGY All consecutive patients with a(More)
BACKGROUND The effect of parenteral GLN on recovery from severe acute pancreatitis has not been thoroughly investigated. The aims of this study were to determine whether parenteral GLN improves nutrition status and immune function, and to determine its ability to reduce morbidity and mortality in patients with this condition. METHODS In a randomized(More)
BACKGROUND The risk of presenting with oesophageal cancer is associated with Barrett's oesophagus, with a higher prevalence in some Asian and African countries. Human papillomavirus (HPV) DNA has been identified in oesophageal carcinomas, which share common features with cervical cancers and originate in stratified epithelium. MATERIALS AND METHODS(More)
BACKGROUND Acute pancreatitis is the most common major complication after endoscopic retrograde cholangiopancreatography (ERCP). Many drugs have been evaluated for prophylaxis, including nonsteroidal anti-inflammatory drugs (NSAIDs), which are potent inhibitors of phospholipase A2 and play a role in the pathogenesis of acute pancreatitis. Rectal NSAIDs have(More)
AIM To assess the efficacy of allopurinol to prevent hyperamylasemia and pancreatitis after endoscopic retrograde cholangiopancreatography (PEP). METHODS One hundred and seventy patients were enrolled and randomized to two groups: a study group (n = 85) who received 300 mg of oral allopurinol at 15 h and 3 h before endoscopic retrograde(More)
Dexamethasone has been reported to reduce postoperative nausea and vomiting (PONV) after laparoscopic cholecystectomy (LC). However, its effects on other surgical outcomes, such as pain and fatigue, have been unclear. We evaluated the efficacy of preoperative dexamethasone for ameliorating postoperative symptoms after LC. In this prospective, double-blind,(More)
A major complication in 30% to 75% of cases of surgical treatment of alveolar cleft is resorption of the bone graft. A treatment alternative is the application of fibrin glue, which has the capacity to favor the integration of the graft. The main objective of the study was to evaluate if the use of the fibrin glue reduces bone resorption when it is applied(More)
BACKGROUND/AIM Facial injury in adults can commonly result in fractures of the mandible. Autologous mesenchymal stem cells (AMSCs) transplantation is proposed as an alternative to conventional graft treatment to improve bone regeneration. The aim was to evaluate the effectiveness of AMSCs application in mandibular fractures to reduce regeneration time and(More)
Gastrocutaneous fistulas are infrequent after gastrostomy tube removal. However, if the fistulous tract remains permeable, even low-volume output can produce significant cutaneous burns. The use of biodegradable adhesives has been described, where fibrin glue is applied directly over the fistulous tract or under the guidance of procedures such as upper or(More)
AIM To assess whether the use of fibrin sealant shortens the closure time of postoperative enterocutaneous fistulas (ECFs). METHODS The prospective case-control study included 70 patients with postoperative ECFs with an output of < 500 mL/d, a fistulous tract of > 2 cm and without any local complication. They were divided into study (n = 23) and control(More)
