BACKGROUND Little data are available about the learning curve for robotic rectal resection. OBJECTIVE The purpose of this work was to provide a multidimensional analysis of the learning process in patients undergoing robotic total mesorectal excision for rectal cancer. DESIGN This was a retrospective review of a prospectively collected database designed(More)
BACKGROUND A robotic system (da Vinci(®) Surgical System, Intuitive Surgical Inc., Sunnyvale, CA, USA) has technical advantages over conventional laparoscopic surgery because it increases the precision and accuracy of anatomical dissection. The present study aimed to compare the short-term outcomes between robot-assisted intersphincteric resection (ISR) and(More)
BACKGROUND Urinary and sexual dysfunction are recognized complications of rectal cancer surgery in men. This study compared robot-assisted total mesorectal excision (RTME) and laparoscopic total mesorectal excision (LTME) with regard to these functional outcomes. METHODS A series of 32 men who underwent RTME between February 1, 2009 and December 31, 2010(More)
BACKGROUND Few studies that meticulously match individual lymph nodes seen on MRI with their precise histologic counterparts after total mesorectal excision have been reported. OBJECTIVE The objective of this study was to determine whether preoperative MRI could detect lymph node metastases accurately in the node-by-node analysis. DESIGN This was a(More)
PURPOSE We evaluated the short- and long-term outcomes of laparoscopic total proctocolectomy with ileal pouch-anal anastomosis (TPC/IPAA) for treatment of familial adenomatous polyposis (FAP). Also, we assessed the oncologic outcomes in FAP patients with coexisting malignancy. METHODS From August 1999 to September 2010, 43 FAP patients with or without(More)
PURPOSE Robotic surgery is known to provide an improved technical ability as compared to laparoscopic surgery. We aimed to compare the efficiency of surgical skills by performing the same experimental tasks using both laparoscopic and robotic systems in an attempt to determine if a robotic system has an advantage over laparoscopic system. METHODS Twenty(More)
PURPOSE This study was conducted to evaluate the technical feasibility and safety of robotic extended lateral pelvic lymph node dissection (LPLD) in patients with advanced low rectal cancer. METHODS A review of a prospectively-collected database at Kyungpook National University Medical Center from January 2011 to November revealed a series of 8(More)
PURPOSE We compared oncologic outcomes of laparoscopic surgery following self-expandable metallic stent (SEMS) insertion with one-stage emergency surgical treatment of obstructive left-sided colon and rectal cancers. METHODS From April 1996 to October 2007, 95 consecutive patients with left-sided obstructive colorectal cancers were included: 25 underwent(More)
BACKGROUND A surgical robot (the da Vinci system) was developed to overcome the disadvantages of laparoscopic surgery, and applications of this system have been widely used. In this study, we present our standardized technique of robotic right colectomy with lymphadenectomy and intracorporeal anastomosis, with an assessment of feasibility in a series of 15(More)
OBJECTIVES The clinical significance of aquaporin-1 (AQP1), aquaporin-3 (AQP3), and aquaporin-5 (AQP5) expression was analyzed in a large number of patients with colon cancer. METHODS AQP1, AQP3, and AQP5 expression was investigated based on the immunohistochemistry of tissue microarray specimens from 486 colon cancer patients who underwent curative(More)
