Surgical management and outcome of rectal carcinoids in a university hospital.

Background: Rectal carcinoids are an uncommon entity comprising only 1%-2% of all rectal tumors. Rectal carcinoids are frequently diagnosed during colonoscopy, but management after polypectomy is still controversial. The aims of this study were to review the surgical procedures for rectal carcinoids and to compare the outcomes of patients after different treatment modalities in a university hospital in Hong Kong.

Detection of colorectal adenoma by narrow band imaging (HQ190) vs. high-definition white light colonoscopy: a randomized controlled trial.

Objectives: The benefits of narrow band imaging (NBI) on enhancing colorectal adenoma detection remain questionable. We tested whether the new generation of NBI (190-NBI), which is twice as bright as the previous version, would improve adenoma detection when compared with high-definition white light (HD-WL) colonoscopy.

Methods: It was a randomized controlled trial with tandem colonoscopy.

Colorectal resection after stent insertion for obstructing cancer: comparison between open and laparoscopic approaches.

Aim: To evaluate surgical outcomes after stent insertion for obstructing colorectal malignancy and to compare between laparoscopic and open approach.

Methods: Surgical resection was performed after stent insertion for malignant colorectal obstruction in 36 patients with a median age of 73 years. Eighteen patients were treated with open resection, whereas 18 underwent a laparoscopic resection.

Survival following laparoscopic versus open resection for colorectal cancer.

Background: This study aimed to compare the overall and disease specific survivals of patients who underwent laparoscopic and open resection of colorectal cancer in a high volume tertiary center.

Methods: Consecutive patients who underwent elective resection for colorectal cancer (open resection, n = 1,197; laparoscopic resection, n = 814) from January 2000 to December 2009 were included. The operative details, postoperative complications, postoperative outcomes, and survival data were collected prospectively.

Enhanced recovery program in laparoscopic colectomy for cancer.

Introduction: Both laparoscopic colectomy and application of enhanced recovery program (ERP) in open colectomy have been demonstrated to enable early recovery and to shorten hospital stay. This study evaluated the impact of ERP on results of laparoscopic colectomy and comparison was made with the outcomes of patients prior to the application of ERP.

Methods: An ERP was implemented in the authors' center in December 2006.

Impact of neoadjuvant treatment on total mesorectal excision for ultra-low rectal cancers.

Background: This study reviewed the impact of pre-operative chemoradiotherapy or post-operative chemotherapy and/or radiotherapy on total mesorectal excision (TME) for ultralow rectal cancers that required either low anterior resection with peranal coloanal anastomosis or abdomino-perineal resection (APR). We examined surgical complications, local recurrence and survival.

Methods: Of the 1270 patients who underwent radical resection for rectal cancer from 1994 till 2007, 180 with tumors within 4 cm with either peranal coloanal anastomosis or APR were analyzed.

Multimodality minimally invasive autopsy--a feasible and accurate approach to post-mortem examination.

Background: Autopsy examination has been the bedrock of western medicine. With the decline in the autopsy rate secondary to the negative psychological impact to the deceased's relatives, the benefits of autopsy have been undermined. Minimally invasive autopsy has been introduced but has not been widely adopted as an alternative to the 'traditional' open approach.

Impact of laparoscopic colorectal resection on surgical site infection.

Objectives: This study aimed to identify the risk factors of surgical site infection (SSI) in elective colorectal resection and the strategy for prevention of SSI in modern era of colorectal surgery.

Background: The practice of colorectal surgery has undergone remarkable evolution recently because of application of laparoscopic resection. This could affect SSI in colorectal patients.

Laparoscopic bowel resection in the setting of metastatic colorectal cancer.

Background: This study aimed to review the outcomes of laparoscopic colorectal resection for patients with stage IV colorectal cancer.

Methods: From the prospectively collected database for patients who underwent surgery for colorectal cancer in our institution, those with stage IV colorectal cancer who underwent elective resection of tumor during the period from January 2000 to June 2006 were included. The outcomes of those with laparoscopic resection were reviewed and comparison was made between patients with laparoscopic and open resection.

Early outcomes of surgery for small bowel obstruction: analysis of risk factors.

Objectives: The study aimed to review the etiologies of patients who underwent surgery for small bowel obstruction (SBO) and to evaluate the risk factors affecting the early postoperative outcomes.

Materials And Methods: A case series of 430 patients (252 men) with a mean age of 64.5 years, who underwent 437 operations for SBO, were retrospectively reviewed.
