The attempt to further reduce operative trauma in laparoscopic cholecystectomy has led to new techniques such as natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopic surgery (SILS). These new techniques are considered to be painless procedures, but no published studies investigate the possibility of different pain scores(More)
A clinical trial was designed to assess the use of preincisional and intraperitoneal ropivacaine, combined or not with normal saline, to reduce pain after laparoscopic cholecystectomy (LC). For this trial, 120 patients were randomly assigned to six groups. For all the patients, preincisional local infiltration of ropivacaine around the trocar wounds was(More)
BACKGROUND Primary torsion of the greater omentum is an uncommon cause of acute abdominal pain that mainly affects adults in their fourth or fifth decade. It was first described by Eitel in 1899. Since then, more than 300 cases have been reported in the published literature. Clinical presentation and imaging findings are often of limited value in the(More)
BACKGROUND Recurrence after laparoscopic ventral hernioplasty is a severe problem despite surgeons' increased experience in recent years. It is well known that the main reasons for recurrences are lack of experience, bad technique, infection, and seroma. The aim of this study was to investigate the events, what caused recurrences, and the technique to(More)
OBJECTIVE The aim of this study was to assess morbidity, mortality, and outcome in select patients after laparoscopic cholecystectomy performed by consultants or by Specialist Registrars (SpRs) and Senior House Officers (SHO), in the General Hospital of Ioannina 'G. Hatzikosta' in northwestern Greece. METHODS Between January 1, 2001 and December 31, 2005,(More)
Surgical interventions activate a cascade of reactions that result in an aseptic inflammatory reaction. This inflammatory response initiates the organism’s innate immunity. Laparoscopic surgery reduces the trauma, and patients benefit from diminished surgical trauma and maintained immune function. Cytokine levels and C-reactive protein (CRP) are related to(More)
Laparoendoscopic single-site (LESS) surgery is an evolution of laparoscopic surgery aiming at decreasing the patient’s parietal trauma associated with abdominal operations. LESS has been found so far to be efficient and have the same good results as the standard four-port laparoscopic cholecystectomy. α-Defensins are antimicrobial peptides of the organism.(More)
BACKGROUND This was a retrospective study that evaluated the surgical outcomes of laparoscopic surgery (LS) for rectal cancer, in comparison with a case control series of open surgery (OS), during an 8-year period. METHODOLOGY Between October 1998 and December 2006, 203 patients with rectal malignancies underwent colectomy; 146 of them had colectomy with(More)
Laparoscopic Nissen fundoplication (LNF) has become established as the procedure of choice in the surgical management of the majority of patients suffering from gastroesophageal reflux disease (GERD). Postoperative paraesophageal herniation has an incidence range up to 7% in the immediate postoperative period. A prospective randomized trial was scheduled to(More)
BACKGROUND This study was designed to analyze and compare plasma levels of 8-isoprostane (8-epiPGF2α), a biomarker of lipid peroxidation, and uric acid (UA), a marker of the antioxidant status, in standard laparoscopic (LC) and laparoendoscopic single-site cholecystectomy (LSSC). MATERIALS AND METHODS Forty patients with noncomplicated cholelithiasis were(More)
