Purpose: Because predicting recurrence intervals and patterns would allow for appropriate therapeutic strategies, we evaluated the clinical and pathological characteristics of early and late recurrences of colorectal cancer.
Methods: Patients who developed recurrence after undergoing curative resection for colorectal cancer stage I-III between January 2000 and May 2006 were identified. Early recurrence was defined as recurrence within 2 years after primary surgery of colorectal cancer.
Background: 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 laparoscopic procedure.
Objective: We compared the clinical outcomes of totally laparoscopic anterior resection with transvaginal specimen extraction (TVSE) with those of the conventional laparoscopic approach with minilaparotomy (LAP) for anastomosis construction and specimen retrieval in left-sided colorectal cancer.
Robotic-assisted transabdominal intersphincteric resection: a technique involving a completely abdominal approach and coloanal anastomosis.

February 2013
Background: As the use of a surgical robot allows for improved dexterity and visual field, we successfully conducted transabdominal intersphincteric resection (ISR) and perineal coloanal anastomosis for a very low lying rectal cancer. The aim of this study was to evaluate the technical feasibility of this procedure.
Materials And Methods: Eight patients underwent robotic-assisted transabdominal ISR with coloanal anastomosis for low rectal cancers.
Article Synopsis
- The study examined the results of laparoscopic total proctocolectomy with ileal pouch-anal anastomosis (TPC/IPAA) in patients with familial adenomatous polyposis (FAP) and assessed outcomes in patients with existing malignancies.
- A total of 43 patients underwent the procedure over 11 years, with an average age of 33, and showed a range of early and long-term complications, but generally favorable results.
- The findings indicated that TPC/IPAA is an effective treatment option for FAP, achieving high disease-free and overall survival rates, even in patients with coexisting cancers.
Robot-assisted right colectomy with lymphadenectomy and intracorporeal anastomosis for colon cancer: technical considerations.

October 2012
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 patients.
Methods: All robotic right colectomies with lymphadenectomy were performed by a single surgeon between April 2009 and March 2010.
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 revealed that a series of 16 consecutive patients underwent single-incision laparoscopic surgery (SILS) for an appendiceal mucocele. Data regarding patient demographics, operating time, conversion, surgical morbidity, lateral lymph node status, and mid-term oncologic result were analyzed.
