Local control of sphincter-preserving procedures and abdominoperineal resection for locally advanced low rectal cancer: Propensity score matched analysis.

Sphincter-preserving procedures (SPPs) for surgical treatment of low-lying rectal tumors have advanced considerably. However, their oncological safety for locally advanced low rectal cancer compared with abdominoperineal resection (APR) is contentious. We retrospectively analyzed cohort data of 1500 consecutive patients who underwent elective resection for stage II-III rectal cancer between 2010 and 2011.

Effectiveness of Pelvic Floor Rehabilitation for Bowel Dysfunction After Intersphincteric Resection for Lower Rectal Cancer.

Background: The aim of this study was to evaluate the effectiveness of pelvic floor rehabilitation (PFR) for patients with bowel dysfunction after intersphincteric resection (ISR) and to compare the treatment response to that of patients after low anterior resection (LAR).

Methods: Thirty patients with postoperative bowel dysfunction for more than 6 months were enrolled and treated with PFR for 6 months.

Results: In the ISR group, significant improvements in the number of bowel movements and the use of antidiarrheal medications were observed, but no significant improvement was observed in the Wexner score (WS) and the fecal incontinence severity index (FISI).

Reappraisal of the lateral rectal ligament: an anatomical study of total mesorectal excision with autonomic nerve preservation.

Purpose: The term "lateral rectal ligament" in surgery for rectal cancer has caused confusion regarding its true existence and contents. In previous studies, investigators claimed the existence of the ligament and described its topographical features as neurovascular structures and their surrounding connective tissues located at the anterolateral aspect of the distal rectum or the posterolateral aspect of the middle rectum. The purpose of this study is to evaluate the structure of the so-called "lateral rectal ligament" in cadaver dissections.

Preventive effect of diverting stoma on anastomotic leakage after laparoscopic low anterior resection with double stapling technique reconstruction applied based on risk stratification.

Introduction: During laparoscopic low anterior resection with double stapling technique reconstruction, it is necessary to securely implement rectal transection and anastomosis to prevent anastomotic leakage (AL). However, risk factors and preventive measures for AL are not known sufficiently. Therefore, this study aimed to elucidate risk factors associated with AL and to clarify strategies to prevent it.

A novel transanal tube designed to prevent anastomotic leakage after rectal cancer surgery: the WING DRAIN.

Purpose: We introduce a novel transanal tube (TAT), named the "WING DRAIN", designed to prevent anastomotic leakage after rectal cancer surgery, and report the fundamental experiments that led to its development.

Materials And Methods: We performed the basic experiments to evaluate the effect of TATs on intestinal decompression, the changes they make in patterns of watery fluid drainage, the changes in their decompression effect when the extension tube connecting the TAT to the collection bag fills with watery drainage fluid, and the variations in intestinal contact and crushing pressure made by some types of TAT.

Results: Any type of TAT contributed to decompression in the intestinal tract.

[A Case of Ascending Colon Cancer Showing Marked Reduction of Ascites by Bevacizumab Combination Chemotherapy].

A 68-year-old woman presented to our hospital with abdominal fullness. Computed tomography(CT)revealed ascites and massive tumors in the abdominal cavity. She was diagnosed with ascending colon cancer with peritoneal dissemination and ovarian metastasis.

Effectiveness of a transanal tube for the prevention of anastomotic leakage after rectal cancer surgery.

Aim: We evaluated the effectiveness and safety of a transanal tube placed for the prevention of anastomotic leakage after rectal surgery.

Methods: Between 2007 and 2011, a total of 243 patients underwent anterior resection using the double stapling technique for rectal cancer at our institution. We excluded 67 patients with diverting stoma and divided the remaining patients into two groups: patients who did not receive a transanal tube and diverting stoma (n = 140; control group) and those who received a transanal tube (n = 36).

Laparoscopic surgery for palliative resection of the primary tumor in incurable stage IV colorectal cancer.

Background: The purpose of the study was to evaluate the feasibility and efficacy of laparoscopic palliative resection in patients with incurable stage IV colorectal cancer.

Methods: We reviewed 100 patients with incurable stage IV colorectal cancer who underwent palliative resection of the primary tumor between 2002 and 2009 at National Cancer Center Hospital East (NCCHE). Outcomes and postoperative course were compared between patients who underwent open and laparoscopic surgery.

Postoperative chylous ascites after colorectal cancer surgery.

Purpose: To evaluate the diagnosis, epidemiology, risk factors, and treatment of chylous ascites after colorectal cancer surgery.

Methods: Among 907 patients who underwent colorectal cancer resection at our institution between 2006 and 2009, chylous ascites developed in 9. We analyzed the clinical data for these 9 patients.
