Pancreatic anastomotic leakage (Leak) is the most common major complication after pancreaticoduodenectomy (PD). In this study we tested the hypothesis that better vision would improve the technical performance of this anastomosis and result in a lower Leak rate. A retrospective review of 266 consecutive patients who underwent PD with pancreaticojejunostomy between 1996 and 2003 was carried out...
Extensive intraductal disease represents an important clinical problem in the management of patients with invasive or in situ breast cancer. The purpose of this study was to determine the value of intraoperative ductoscopy for detection of intraductal neoplasia in women with breast cancer. Intraoperative ductoscopy was performed in 54 women undergoing operation for breast cancer. A rigid gradient...
The ability of malignant tumors to metastasize presents a severe challenge in cancer treatment. Lymphatic vessels provide one of the main routes for tumor-metastasis on the way to regional lymph nodes. Increasing evidence suggests that inflammatory cells play an important role in tumor-associated angiogenesis and lymphangiogenesis. Recent data show that a specialized sub fraction of tumor-associated...
Laparoscopic suturing has been regarded as an advanced operative task, and courses to develop this skill are aimed at senior trainees and consultants. This study evaluates the role of laparoscopic suturing courses in the modern operative training curriculum. The performance of 9 senior operative trainees (course A) was compared to that of 14 junior operative trainees (course B) at identical, 2-day...
A right liver graft used almost routinely for adult living donor liver transplantation (LDLT), is associated with a higher incidence of morbidity and mortality in the donor. We compared volume regeneration and graft function between left and right liver grafts to examine the feasibility of using left liver grafts. The left liver was considered acceptable as a graft when it was estimated to be over...
Activating mutations in the RET gene, which encodes a tyrosine kinase receptor, often cause medullary thyroid carcinoma (MTC). Surgical resection is the only curative treatment; no effective systemic treatment is available. We evaluated imatinib, a tyrosine kinase inhibitor currently used to treat chronic myelogenous leukemia and gastrointestinal stromal tumors, as a potential drug for systemic treatment...
The surgical success rate of parathyroidectomy is 95%. However, in rare patients, ectopic hyperfunctioning parathyroid glands may be located in the thyroid but missed on imaging studies or during surgery. The aim of the present study was to evaluate the perioperative findings in 6 patients with intrathyroid parathyroid glands treated for hyperparathyroidism in our center over a 5-year period and to...
Liver xenotransplantation presents, apart from immunologic problems, metabolic incompatibilities between species. The liver plays a key role in blood coagulation. The aim of this study is to describe the hemostatic status of long-term surviving xenografts in a hamster-to-rat liver xenotransplantation model. Orthotopic liver transplantation with Tacrolimus and MMF was carried out with Golden Syrian...
Many surgeons believe that long turnover times between cases are a major impediment to their productivity. We hypothesized that redesigning the operating room (OR) and perioperative-staffing system to take advantage of parallel processing would improve throughput and lower the cost of care. A state of the art high tech OR suite equipped with augmented data collection systems served as a living...
The aim of this prospective study was to determine whether the change between the initial and subsequent analysis of serum inflammatory markers measured 6 to 10 hours later could improve diagnostic accuracy in appendicitis. The study group comprised 225 patients who presented to hospital with equivocal signs of appendicitis from 2003 to 2004. Based on the period from the onset of symptoms to admission,...
