BACKGROUND Laparoscopy was initially considered to be a risky procedure for rectal cancer patients, especially patients with an increased body weight. The literature is scarce regarding the effects of obesity on laparoscopic rectal surgery. The aim of the current study was to analyze the effect of an increased body mass index (BMI) on outcome of(More)
BACKGROUND The impact of conversion on postoperative outcomes of laparoscopic colorectal surgery remains controversial. The purpose of this study was to assess whether a conversion results in increased postoperative morbidity and mortality, and to evaluate whether any specific factors affect the outcomes of converted procedures. METHODS Outcomes of(More)
The effectiveness of laparoscopic intestinal resection in patients with previous midline laparotomy (PML) is controversial. The aim of this study was to assess the feasibility of laparoscopic surgery and identify possible factors associated with postoperative outcomes in patients with PML. Patients with PML (at least an infraumbilical incision or longer)(More)
Obese patients pose additional operative technical difficulties, and it is unclear if the outcomes of single-port colorectal surgery are equivalent to those of conventional laparoscopy in such patients. The aim of this study was to compare perioperative variables and short-term outcomes of single-port versus conventional laparoscopy in obese patients(More)
BACKGROUND Few studies have been published on liver resection alone or in combination with cytoreductive surgery for liver metastases of ovarian carcinoma. METHODS Eight patients who underwent liver resection for metastasis of ovarian cancer were included in the study. Total abdominal hysterectomy and bilateral salpingo-oophorectomy had been performed(More)
Effects of iloprost on visual evoked potentials and oxidant/antioxidant status were evaluated after bilateral carotid artery occlusion. There were three experimental groups; Sham (S) group (n=10), bilateral common carotid artery occluded (BCCAO) group (n=10) and after bilateral common carotid artery occlusion, iloprost-treated (BCCAOI) group (n=10).(More)
Operative approach for right colectomy has progressed substantially in last decades, by the application of laparoscopy in colorectal surgery. Single-port (SP) laparoscopic surgery is one of the newest branches of advanced laparoscopy. A 29-year-old woman with ileocecal Crohn's disease underwent a totally laparoscopic transumbilical SP right colectomy,(More)
OBJECTIVE To evaluate the effects of iloprost administration before unilateral nephrectomy on postoperative interleukin-6 (IL-6), nitric oxide (NO), and oxidant/antioxidant status. METHODS Malondialdehyde, glutathione, catalase and Cu-Zn superoxide dismutase were measured in the blood and remnant kidney of Adult male Wistar albino rats to assess oxidant(More)
BACKGROUND Robotic surgery is thought to be a solution to overcome the limitations of laparoscopy in sphincter-saving resections. In this study, we present our results on patients undergoing robotic and laparoscopic low anterior resection (LAR) consecutively for rectal adenocarcinoma. MATERIALS AND METHODS Between February 2008 and June 2011, consecutive(More)
BACKGROUND Increased free radical production, decreased antioxidant capacity and excessive inflammation are well-known features in the pathogenesis of inflammatory bowel disease. Vitamin E is a powerful antioxidant and a scavenger of hydroxyl radicals, and it has been shown to have anti-inflammatory activities in tissues. We investigated the effects of(More)
