Professor Nam Kyu Kim's research lab specializes in colorectal cancer surgery, with a focus on improving surgical outcomes through advanced imaging, minimally invasive techniques, and oncologic staging. The lab investigates optimal preoperative assessment methods such as transrectal ultrasonography and MRI, evaluates surgical strategies like double-stapling technique and robotic surgery, and emphasizes the preservation of pelvic autonomic nerves to maintain quality of life. Key research directions include minimizing complications, enhancing oncologic outcomes, and refining surgical staging and treatment protocols for rectal cancer.
Figures are computed from collected data and may differ slightly.
Both transrectal ultrasonography and magnetic resonance imaging with endorectal coil exhibited similar accuracy and were superior to conventional computed tomography in preoperative assessment of depth of invasion and adjacent organ invasion. Because transrectal ultrasonography is a safer and more cost-effective modality than magnetic resonance imaging, transrectal ultrasonography is an appropriate method for preoperative staging of rectal cancer. Further efforts will be needed to provide a bett
A reduction in the number of linear stapler firings is necessary to avoid anastomotic leakage after laparoscopic colorectal anastomosis with a double stapling technique. We recommend that a diverting ileostomy is mandatory in patients with middle and lower rectal cancer where multiple linear staplers were used.
Total mesorectal excision with pelvic autonomic nerve preservation showed relative safety in preserving sexual and voiding function. The International Prostate Symptom Score and International Index of Erectile Function questionnaires were useful in assessing urinary and sexual function.
Pathologic complete remission showed excellent oncologic outcomes, and the pathologic N stage was the most important factor for oncologic outcomes.
These data show that insertion of SEMS as a bridge to surgery in the management of left-sided colon cancer obstruction is possibly associated with adverse oncologic outcomes compared with nonobstructing elective surgery, but it is unclear what magnitude of this effect is related to the underlying obstruction rather than to the SEMS.
The true benefits of robotic surgery are controversial, and whether robotic total mesorectal excision (R-TME) can be justified as a standard treatment for rectal cancer patients needs to be clarified. This case-matched study aimed to compare the postoperative complications and short- and long-term outcomes of R-TME and laparoscopic TME (L-TME) for rectal cancer.Among 1029 patients, we identified 278 rectal cancer patients who underwent R-TME. Propensity score matching was used to match this grou
