BACKGROUND Although early reports on laparoscopy-assisted colectomy (LAC) in patients with colon cancer suggested that it reduces perioperative morbidity, its influence on long-term results is unknown. Our study aimed to compare efficacy of LAC and open colectomy (OC) for treatment of non-metastatic colon cancer in terms of tumour recurrence and survival.(More)
OBJECTIVE The aim of this study was to compare the long-term outcome of laparoscopy-assisted colectomy (LAC) and open colectomy (OC) for nonmetastatic colon cancer. METHODS From November 1993 to July 1998 all patients with adenocarcinoma of the colon were assessed for entry in this single center, clinically randomized trial. Adjuvant therapy and(More)
OBJECTIVE The aim of this study was to compare short-term results obtained with transanal total mesorectal excision (TME) and laparoscopic surgery. BACKGROUND Transanal TME appears as an alternative in the treatment of rectal cancer and other rectal disease. Natural orifices transluminal endoscopic surgery using the rectum as access in colorectal surgery(More)
The transanal minilaparoscopy-assisted natural orifice transluminal endoscopic surgery (NOTES) approach holds significant promise as a safe and less morbid alternative to conventional low anterior rectal resection. Previous reports have shown satisfactory short-term oncologic results. We evaluated the safety and short-term outcomes in rectal cancer subjects(More)
The authors examined the impact of the laparoscopic approach on the early outcome of resected colon carcinomas. The role of laparoscopic techniques in the treatment of colon carcinomas is questionable. Previous studies have suggested technical feasibility of surgical resections of these cancers by laparoscopic means and have implied a benefit to(More)
Natural orifice translumenal endoscopic surgery (NOTES) represents the evolution of surgery towards less invasive procedures. The feasibility of NOTES transrectal approach has increased its clinical applicability. This report describes a first series of minilaparoscopy-assisted transrectal low anterior resection with double purse-string end-to-end circular(More)
PURPOSE Although systematic postoperative surveillance of patients with colorectal cancer has been demonstrated to improve survival, it remains unknown whether a more intensive strategy provides any significant advantage. This prospective, multicenter, randomized, controlled trial was aimed at comparing the efficacy of two different surveillance strategies(More)
CONTEXT The mechanisms underlying weight loss after Roux-en-Y gastric bypass (RYGBP) are not well understood. OBJECTIVE The objective of the study was to assess the changes in active glucagon-like peptide 1 (GLP-1) and total peptide YY (PYY) after RYGBP and examine their relationship with changes in hunger and satiety. DESIGN This was a prospective(More)
OBJECTIVE To perform a meta-analysis of trials randomizing patients with colon cancer to laparoscopically assisted or open colectomy to enhance the power in determining whether laparoscopic colectomy for cancer is oncologically safe. DATA SOURCES The databases of the Barcelona, Clinical Outcomes of Surgical Therapy (COST), Colon Cancer Laparoscopic or(More)
With available laparoscopic and endoscopic instruments/technology a standard radical sigmoid resection is feasible and safe using transvaginal minilaparoscopic-assisted natural orifice surgery (MA-NOS). The intervention was a transvaginal MA-NOS sigmoidectomy in a 78-year-old woman with a sigmoid adenocarcinoma. Maintaining triangulation the surgeon(More)
