Predictive factors and the prognosis of recurrence of colorectal cancer within 2 years after curative resection.

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.

Transvaginal specimen extraction versus conventional minilaparotomy after laparoscopic anterior resection for colorectal cancer: mid-term results of a case-matched study.

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.

Laparoscopic cytoreductive surgery and early postoperative intraperitoneal chemotherapy for patients with colorectal cancer peritoneal carcinomatosis: initial results from a single center.

Background: In recent decades, a combination of cytoreductive surgery and intraperitoneal chemotherapy has yielded improvements in the survival of patients with peritoneal carcinomatosis. Laparoscopic cytoreductive surgery and intraperitoneal chemotherapy comprise a challenging and rarely reported surgical procedure.

Methods: Between November 2004 and February 2010, 29 patients underwent cytoreductive surgery and early postoperative intraperitoneal chemotherapy for peritoneal carcinomatosis secondary to colorectal cancer.

Urinary and erectile function in men after total mesorectal excision by laparoscopic or robot-assisted methods for the treatment of rectal cancer: a case-matched comparison.

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 were matched 1:1 with patients who underwent LTME.

Robotic-assisted transabdominal intersphincteric resection: a technique involving a completely abdominal approach and coloanal anastomosis.

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.

Short-term clinical outcome of robot-assisted intersphincteric resection for low rectal cancer: a retrospective comparison with conventional laparoscopy.

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 laparoscopic ISR for distal rectal cancer.

Influence of surgical manipulation and surgical modality on the molecular detection of circulating tumor cells from colorectal cancer.

Purpose: The aim of this study was to evaluate the relationship between the detection of circulating tumor cell molecular markers from localized colorectal cancer and the time-course of a surgical manipulation or surgical modality.

Methods: From January 2010 to June 2010, samples from the peripheral blood and the inferior mesenteric vein were collected from 42 patients with cancer of the sigmoid colon or rectum. Pre-operative, intra-operative (both pre-mobilization and post-mobilization), and post-operative samples were collected.

Single-incision Laparoscopic Surgery for Appendiceal Mucoceles: Safety and Feasibility in a Series of 16 Consecutive Cases.

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.

Abdominal aortic aneurysm repair in patient with a renal allograft: a case report.

Renal transplant recipients requiring aortic reconstruction due to abdominal aortic aneurysm (AAA) pose a unique clinical problem. The concern during surgery is causing ischemic injury to the renal allograft. A variety of strategies for protection of the renal allograft during AAA intervention have been described including a temporary shunt, cold renal perfusion, extracorporeal bypass, general hypothermia, and endovascular stent-grafting.
