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)
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 laparoscopic(More)
Although the vagina is considered a viable route during laparoscopic surgery, a number of concerns have led to a need to demonstrate the safety of a transvaginal approach in colorectal surgery. However, the data for transvaginal access in left-sided colorectal cancer are extremely limited, and no study has compared the clinical outcomes with a conventional(More)
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. From April 1996 to October 2007, 95 consecutive patients with left-sided obstructive colorectal cancers were included: 25 underwent preoperative(More)
PURPOSE The aim of this study was to evaluate the technical feasibility, safety, and oncological outcomes of transumbilical single-incision laparoscopic surgery in patients with an uncomplicated appendiceal mucocele. METHODS A review of a prospectively collected database at the Kyungpook National University Hospital from January 2006 to September 2010(More)
Endometrial carcinoma is the most common gynecologic cancer, yet the mechanisms underlying this disease process are poorly understood. We hypothesized that Lef1 is required for endometrial gland formation within the uterus and is overexpressed in endometrial cancer. Using Lef1 knockout (KO) mice, we compared uterine gland development to wild-type (WT)(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)
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. A series of 32 men who underwent RTME between February 1, 2009 and December 31, 2010 were matched 1:1 with(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)
