Background: To investigate the similarities and differences of laparoscopic complete mesocolic excision (CME) to a colon resection with a D3 lymphadenectomy for the stage II/III left-sided colon carcinoma.

Methods: Patients between July 2011 and August 2014 were randomized into D3 and CME groups. Mesenteric area, log odds of positive lymph nodes (LODDS), and other operative parameters were collected and assessed.

Challenge or opportunity: outcomes of laparoscopic resection for rectal cancer in patients with high operative risk.

This study investigated the impact of laparoscopic rectal cancer resection for patients with high operative risk, which was defined as American Society of Anesthesiology (ASA) grades III and IV. This study was conducted at a single center on patients undergoing rectal resection from 2006 to 2010. After screening by ASA grade III or IV, 248 patients who met the inclusion criteria were identified, involving 104 open and 144 laparoscopic rectal resections.

Objective: The purpose of this study was to evaluate the feasibility, the safety, and outcomes of renal replacement therapy with the laparoscopic technique for peritoneal dialysis (PD) catheter implantation with an intra-abdominal fixation.

Methods: Medical records of 53 patients with end-stage renal disease who underwent laparoscopic PD catheter implantation with an intra-abdominal fixation in our department from December 2008 to October 2009 were reviewed retrospectively. Their surgical procedure, operative outcomes, postoperative complications, and follow-up outcomes were analyzed.

[Clinical prognostic multivariate analysis of incidental gallbladder cancer: a case controlled retrospective study].

Objective: To investigate the prognostic risk factors in incidental gallbladder cancer (IGBC) and evaluate the effect of laparoscopic cholecystectomy (LC) applied in treating IGBC.

Methods: The retrospective study enrolled 55 patients with incidental gallbladder adenocarcinoma treated between January 2001 and December 2008. The patients were divided into three groups according to different surgical approaches: laparoscope group (n = 23), conversion group (n = 6) and laparotomy group (n = 26).

Direct and indirect costs and long-term survival of laparoscopic anterior resection for rectal cancer.

Background: Few studies evaluate the cost-effectiveness issues of laparoscopic anterior resection (LAR) for rectal cancer. This study evaluates direct and indirect costs of LAR and its long-term survival rate in rectal cancer patients.

Material/methods: This prospective nonrandomized controlled trial included 2 endpoints (direct and indirect costs, and disease-free survival).

Long-term outcome of laparoscopic total mesorectal excision for middle and low rectal cancer.

This study aimed to assess the feasibility and long-term outcome of laparoscopic total mesorectal excision for middle and lower rectal cancer. Retrospective assessment was performed on 612 patients with middle and low rectal cancer in the surgery department of our hospital. Three-hundred and three patients underwent laparoscopic total mesorectal excision (LTME), and 309 patients underwent open TME (OTME).

Laparoscopic low anterior resection for rectal carcinoma: complications and management in 132 consecutive patients.

Aim: To analyze the clinical manifestations and risk factors of complications in laparoscopic low anterior resection (LAR) for rectal cancer patients.

Methods: A series of 132 consecutive patients who received laparoscopic LAR for rectal cancer in our center were included. The etiology, diagnosis, treatment and prevention of rectal cancer were studied among the patients with surgery-related complications using both univariate and multivariate regression analysis.

[Impact of previous abdominal operations on the outcome of laparoscopic colorectal cancer surgery: a non-randomized cohort study].

Objectives: To investigate the impact of previous abdominal operations on the outcome of laparoscopic colorectal cancer surgery and to evaluate the feasibility and safety of laparoscopic reoperation in treatment for colorectal cancer.

Methods: According to the statistical standards, 653 consecutive patients treated from March 2002 and March 2009 were enrolled in this study. The patients were divided into three groups: upper abdominal surgery group (n = 48), middle-lower abdominal surgery group (n = 110) and non-previous abdominal surgery group (n = 495).

Intraoperative cholangiography in combination with laparoscopic ultrasonography for the detection of occult choledocholithiasis.

Background: There is still a debate about the utility of intraoperative cholangiography (IOC) or laparoscopic ultrasonography (LUS) for detection of occult choledocholithiasis during laparoscopic cholecystectomy (LC). The aim of this study was to assess the value of IOC combined with LUS for detection of occult common bile duct (CBD) stones at LC.

Material/methods: From Dec 2002 to Aug 2006, 103 patients with moderate risk of CBD stones underwent IOC and LUS simultaneously during LC.

[Safety study of laparoscopic surgery for colorectal cancer in elderly patients].

Objective: To compare the outcomes of laparoscopic colorectal surgery in elderly (> or = 70 years) and younger(< 70 years) patients, and to evaluate the safety of laparoscopic colorectal surgery in elderly.

Methods: From Aug. 2007 to Dec.

Simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach.

Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity, a shorter treatment time, and similar outcomes. However, simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature. Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort.

[Comparison of inflammatory response after laparoscopic and conventional surgery for colorectal carcinoma].

Objective: To compare the systemic and local inflammatory response after laparoscopic and conventional surgery for colorectal carcinoma.

Methods: From April 2004 to August 2004, 51 colorectal cancer patients undergoing laparoscopic (n=25) and conventional open (n=26) colorectal resection were enrolled in the study. The general clinical data,and inflammatory response were compared between the two groups.

Clinical advantages of laparoscopic colorectal cancer surgery in the elderly.

Background And Aims: Elderly patients have a high incidence of colorectal cancer, which may be associated with increased morbidity and mortality due to complex comorbidity and diminished cardiopulmonary reserves. The aims of this study were to compare the outcomes of laparoscopic colorectal cancer surgery with those observed in traditional open surgery in patients aged over 70 years.

Methods: Between January 2003 and October 2004, 51 patients aged over 70 years with colorectal cancer, who underwent laparoscopic surgery (LAP group), were evaluated and compared with 102 controls (also over 70 years old) treated by traditional open surgery (OPEN group) in the same period.

[Experience of laparoscopic salvage surgery for locally recurrent rectal cancer].

Objective: To investigate the feasibility of the laparoscopic salvage surgery for locally recurrent rectal cancer.

Methods: Seven cases with recurrent rectal carcinoma treated by laparoscopic salvage surgery from February 2004 to July 2005 were retrospectively analyzed. Among them, four were males and 3 females, and the median age was 60 years (range 37-74).

Laparoscopic pancreaticoduodenectomy for ductal adenocarcinoma of common bile duct: a case report and literature review.

Background: Minimal access techniques have gained wide acceptance in surgical practice, but the role of laparoscopic pancreaticoduodenectomy is still controversial. Laparoscopic pancreaticoduodenectomy has seldom been described. In this report, we assessed the feasibility and safety of laparoscopic pancreaticoduodenectomy for ductal adenocarcinoma of the common bile duct.

Laparoscopic versus open right hemicolectomy with curative intent for colon carcinoma.

Aim: Laparoscopic surgery, especially laparoscopic rectal surgery, for colorectal cancer has been developed considerably. However, due to relatively complicated anatomy and high requirements for surgery techniques, laparoscopic right colectomy develops relatively slowly. This study was designed to compare the outcomes of laparoscopic right hemicolectomy (LRH) with open right hemicolectomy (ORH) in the treatment of colon carcinoma.
