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)
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)
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)
BACKGROUND The impact of obesity per se on the surgical strategy, ie, sphincter sacrifice (abdominoperineal resection) vs sphincter-preserving resection, outcomes, and long-term maintenance of intestinal continuity has been poorly studied in patients with mid and low rectal cancer. OBJECTIVE The aim of this study is to compare the outcomes and long-term(More)
HYPOTHESIS Single-port laparoscopic rectal surgery can be performed using the principles of oncologic surgery in institutes experienced in laparoscopy with the advantages of minimally invasive surgery. DESIGN Sphincter-saving mesorectal excision in 4 human cases via a single laparoscopic port. SETTINGS A university hospital and a private hospital. (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)
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)
PURPOSE In this study, the effects of intravenous paracetamol treatment on early postoperative period analgesia and recovery characteristics after laparoscopic cholecystectomy have been evaluated. METHODS Forty patients whose American Society of Anesthesiologists physical status I or II underwent laparoscopic cholecystectomy and randomly divided into 2(More)
