OBJECTIVE Transanal endoscopic microsurgery (TEM) allows locally complete excision of rectal neoplasms and provides an alternative to conventional surgery for benign tumours. However, its role in the curative treatment of invasive carcinoma is controversial. This paper examines the results of TEM compared with radical surgery (RS) for T1 rectal cancer. (More)
OBJECTIVE Transanal endoscopic microsurgery (TEM), a minimally invasive technique has been employed in the excision of benign and well-selected malignant rectal tumours since June 1998. We present a prospective descriptive study and analyse the currently accepted indications. PATIENTS AND METHODS Over a 4-year period 100 patients underwent TEM for(More)
Increasing the rate of pathological complete remissions after neoadjuvant chemoradiation of rectal cancer has become a strategy to further improve the long-term oncological outcome of patients. This report evaluates the influence of preoperative intensified radiochemotherapy on the rate and outcome of surgical complications. Patients with primary rectal(More)
Hand-assisted laparoscopic surgery (HALS) has been proposed as a useful alternative to conventional laparoscopic and open surgery. As compared with conventional laparoscopic surgery, it offers the advantages of tactile feedback, better exposure, and a shorter learning curve. There is increasing evidence that HALS retains the advantages of minimal-access(More)
This quantitative in vivo fluorescence microscopy study investigated the relative impact of an optimized rinse solution (warm Carolina rinse) and that of an established storage solution (University of Wisconsin solution) on various pathomechanisms of hepatic reperfusion injury after cold storage. Syngeneic orthotopic, arterialized liver transplantation was(More)
BACKGROUND Visceral artery aneurysms (VAA), although uncommon, are increasingly being detected. We describe a case of spontaneous retroperitoneal hemorrhage from a ruptured IMA aneurysm associated with stenosis of the superior mesenteric artery (SMA) and celiac trunk, successfully treated with surgery. METHODS A 65-year-old man presented with abdominal(More)
Tumours within the retrorectal space are uncommon. Due to their rarity and diverse symptoms they are often misdiagnosed or mistreated. We report three cases of women presenting a variety of symptoms including increased rectal pain, recurrent abscesses/fistulas and constipation. Upon clinical examination and further investigations using MR scan, endorectal(More)
OBJECTIVES Chronic infection with oncogenic HPV genotype is associated with the development of anal dysplasia. Antiretroviral therapy (ART) has been shown to decrease the incidence of cervical carcinoma in women with HIV. We sought to: 1) describe the prevalence and grade of anal dysplasia and HPV infection in our study subjects; 2) analyze the grade of(More)
OBJECTIVE This study analyzed the pathophysiologic sequela of different modes of graft reperfusion in liver transplantation. SUMMARY BACKGROUND DATA The grafted liver may be reperfused either immediately after completion of portal anastomosis followed by delayed arterial reconstruction or simultaneously by portal and arterial blood if all vascular(More)
