Laparoscopic-assisted versus open resection of right-sided colonic cancer--a prospective randomized controlled trial.

Purposes: This study aims to compare the perioperative outcomes and survival between laparoscopic-assisted right hemicolectomy (LARH) and open right hemicolectomy (ORH) for right-sided colon cancer.

Methods: Between July 1996 and October 2005, 145 patients were randomized to receive LARH (n = 71) or ORH (n = 74).

Results: The median follow-up of living patients was 99.

Emergency laparoscopic-assisted right hemicolectomy: can we achieve outcomes similar to elective operation?

The aim of this study was to compare short-term clinical outcomes of elective and emergency laparoscopic-assisted right hemicolectomy. Between January 2005 and December 2009, 181 patients had laparoscopic-assisted right hemicolectomy performed at our institute (148 elective and 33 emergency cases). The demographic data, operative details, and short-term outcomes were collected.

Chinese validation of Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire.

Introduction And Hypothesis: The purpose of this study was to investigate the reliability and validity of the Chinese version of Pelvic Floor Distress Inventory (PFDI) and Pelvic Floor Impact Questionnaire (PFIQ).

Methods: Women who presented for pelvic floor disorders completed the Chinese version of PFDI and PFIQ, SF-36, a 3-day urinary and fecal diary. POP-Q assessment, urodynamic study, anal manometry, and ultrasound were performed where appropriate.

Giant Meckel's diverticulitis: a rare condition complicating pregnancy.

A 33-year-old pregnant woman presented with peritonitis at the right iliac fossa. Preoperative ultrasonography identified an 8-cm tubular structure at the tender point that was mistaken as appendicitis. Emergency operation finally confirmed a 12-cm giant Meckel's diverticulum with genuine inflammation and imminent perforation.

Telerobotic-assisted laparoscopic abdominoperineal resection for low rectal cancer: report of the first case in Hong Kong and China with an updated literature review.

Telerobotic surgery is the most advanced development in the field of minimally invasive surgery. The da Vinci surgical system, which is currently the most widely used telerobotic device, was approved by the Food and Drug Administration of the United States of America for clinical use in all abdominal operations in July 2000. The first da Vinci surgical system in China was installed in November 2005 at our institution.

Outcome of radical excision of anorectal gastrointestinal stromal tumors in Hong Kong Chinese patients.

Anorectal gastrointestinal stromal tumor (GIST) is a rare disease entity with malignant potential. Medical records of six patients (median age 68 years) with anorectal GIST who underwent surgical treatment at our institution between 1992 and 1999 were retrospectively reviewed. Four patients presented with rectal bleeding.

Portal venous gas and thrombosis in a Chinese patient with fulminant Crohn's colitis: a case report with literature review.

Ever since its earliest reports, portal venous gas (PVG) has been associated with numerous intraabdominal catastrophes and has served as an indication for urgent surgical exploration. It is traditionally regarded to be an ominous finding of impending death, with highest mortality reported in patients with underlying bowel ischemia. Today, computed tomography has demonstrated a wider range of clinical conditions associated with PVG, some of which are "benign" and do not necessarily require surgery, unless when there are signs of intraabdominal catastrophe or systemic toxicity.

Polypoid lesions of the gallbladder.

Background: Polypoid lesions of the gallbladder encompass a wide variety of pathology. Although most of these lesions are benign, some early carcinomas of the gallbladder do present as polypoid lesions. Problems remain in selecting patients with polypoid lesions of the gallbladder for surgery, the operative approach, and the method of follow-up of those deemed not needing surgery.
