OBJECTIVE: To assess the safety, feasibility and clinical outcome of laparoscopic radical resection for low rectal cancer with telescopic anastomosis or with colostomy by stapler through transanal resection without abdominal incisions. METHODS: From January 2010 to September 2014, 37 patients underwent laparoscopic radical resection for low rectal cancer through transanal resection without abdominal incisions. The tumors were 4-7 cm above the anal verge. On preoperative assessment, 26 cases were T1N0M0 and 11 were T2N0M0...

Colorectal cancer (CRC) is a common neoplasia in the Western countries, with considerable morbidity and mortality. Every fifth patient with CRC presents with metastatic disease, which is not curable with radical intent in roughly 80% of cases. Traditionally approached surgically, by resection of the primitive tumor or stoma, the management to incurable stage IV CRC patients has significantly changed over the last three decades and is nowadays multidisciplinary, with a pivotal role played by chemotherapy (CHT)...

Surgery has still a key role in curative treatment of digestive carcinomas, and for almost all localisations, lymph node status is a major prognostic factor. As far as oesophageal and gastric cancer are concerned, there is not yet any internationally standardized approach. Occidental guidelines recommend more limited lymph node dissections than Asiatic ones. Lymph node numbers requested during surgery of such cancers remain high, at least 23 lymph nodes for oesophageal cancer, and 25 for a D2 or D1.5 lymphadenectomy for gastric cancer...

Laparoscopic colorectal surgery has rapidly developed since the 1980s. Relative to open surgery, it offers the benefits of less invasiveness and earlier recovery. However, when a mini-laparotomy wound is needed to retrieve the specimen, the benefits of minimally invasive surgery may be compromised as a result of pain- and wound-related complications. The introduction of natural orifice transluminal endoscopic surgery (NOTES) makes "scarless" surgery a possibility; pain- and wound-related complications are totally abolished...

BACKGROUND: We conducted a randomized study of a laparoscopic technique for removing left-sided colon tumors that can reduce postoperative pain and other wound-related complications compared to the conventional technique. It is a novel technique of hybrid natural orifice translumenal endoscopic surgery (NOTES) colectomy (HNC) whereby laparoscopic colonic mobilization, transection, and anastomosis are performed intracorporeally. The specimen is then delivered through the anus using the transanal endoscopic operation (TEO) device, precluding the need for mini-laparotomy...

BACKGROUND: To demonstrate the feasibility of an innovative technique for the surgical management of rectal cancer, we performed transanal minimally invasive surgery assisted low anterior resection with total mesorectal excision (TAMIS-assisted LAR with TME) in a cadaver model. Transanal LAR via natural orifice transluminal endoscopic surgery has been reported in cadaveric series using rigid transanal platforms. This procedure has not been described using a combination of a single incision laparoscopy and TAMIS transanal endoscopic platform...

INTRODUCTION: Given the limitation of surgical access and instrumentation, pure NOTES technique currently appears challenging for colorectal surgery. As such, we would like to determine the technical feasibility and clinical results of hybrid NOTES right hemicolectomy with transrectal extraction of specimen. MATERIALS AND SURGICAL TECHNIQUE: After the right-sided colon was fully mobilized and vessels ligated, bowel resection and intracorporeal side-to-side ileocolic anastomosis were performed with endostaplers...

Thanks to the great development of laparoscopic surgery and his continuous technical evolution, echography plays more and more important role in the pre- and intraoperative diagnosis. In the hepato-pancreatic pathology the use of the laparoscopic echography reduces clearly the role of laparotomic exploration. In laparoscopic surgery of rectal-colon, the echography is more specific and sensitive in compared with pre-operative MR and CT to individualize liver metastasis, to locate them. This allows the treatment of such lesions through the cryosurgery...
