Laparoscopic surgery for rectal cancer is much more challenging than that for colon cancer because of the confined space within the pelvis. Further, because of the tumor's location in the pelvis, maintenance of resection margins is of greater concern. Nonrandomized studies by groups experienced in laparoscopic surgery have shown both that it produces short-term outcomes equivalent to those for ...

BACKGROUND Polyarteritis nodosa (PAN) is a primary systemic necrotizing vasculitis with diffuse organ involvements, resulting in a high mortality rate due to multiple organ failure. Although the small bowel is the frequently targeted organ of PAN-associated vasculitis, rectal involvement is very rare, and only one case of rectal bleeding has been previously reported. The mortality rate of PAN w...

Laparoscopic surgery for colorectal cancer has been shown to be less invasive than open surgery, while maintaining a similar safety level in many clinical trials. Furthermore, there are no significant differences between laparoscopic surgery and open surgery with respect to the long-term outcomes in colon cancer. Thus, laparoscopic surgery has been accepted as one of the standard treatments for...

During the last decade, robotic surgery for rectal cancer has rapidly gained acceptance among colorectal surgeons worldwide, with well-established safety and feasibility. The lower conversion rate and better surgical specimen quality of robotic compared with laparoscopic surgery potentially improves survival. Earlier recovery of voiding and sexual function after robotic total mesorectal excisio...

SHORT-COURSE RADIOTHERAPY FOLLOWED BY DELAYED SURGERY BECOMES A VALIDATED ALTERNATIVE TO TREAT INTERMEDIATE-RISK LOCALISED RECTAL CANCER The full publication in Lancet Oncology of the Stockholm III trial helps us to understand that short-course radiotherapy in patients with localised rectal cancer could also be followed by delayed surgery. During more than 14 years, more than 800 patients with ...

Robotic surgery, used generally for colorectal cancer, has the advantages of a three-dimensional surgical view, steadiness, and seven degrees of robotic arms. However, there are disadvantages, such as a decreased sense of touch, extra time needed to dock the robotic cart, and high cost. Robotic surgery is performed using various techniques, with or without laparoscopic surgery. Because the resu...

the aim of this study was to evaluate the morbidity and mortality in patients with operable stage ii and iii rectal cancers within one or two months after surgery, who has been treated pre-operatively with short course radiotherapy. twenty-eight patients with rectal adenocarcinoma, consecutively referred to the cancer institute of imam khomeini hospital from march 2009 to march 2010, were selec...

PURPOSE The safety and the feasibility of performing laparoscopic surgery for rectal cancer after preoperative chemoradiotherapy (CRT) have not yet been established. Thus, the aim of this study was to evaluate the efficacy and the safety of laparoscopic rectal cancer surgery performed after preoperative CRT. METHODS We enrolled 124 consecutive patients who underwent laparoscopic surgery for r...
