Long-term outcome of indwelling colon observed seven years after radical resection for rectosigmoid cancer: A case report.

Background: Indwelling colon is characterized by an excluded segment of the colon after surgical diversion of the fecal stream with colostomy so that contents are unable to pass through this part of the colon. We report a rare case of purulent colonic necrosis that occurred 7 years after surgical colonic exclusion.

Case Summary: A 73-year-old male had undergone extended radical resection for rectosigmoid cancer.

Hand-assisted laparoscopic right hemicolectomy with complete mesocolic excision and central vascular ligation: a novel technique for right colon cancer.

Background: It can be difficult to locate the superior mesenteric vein and dissect around middle colic vessels during laparoscopic right hemicolectomy with complete mesocolon excision due to a high rate of vascular variations in the superior mesenteric vessels. Therefore, we report a modified technique for hand-assisted laparoscopic right hemicolectomy with complete mesocolic excision and central vascular ligation, which addresses these two problems.

Methods: Thirty-one consecutive patients with right colon cancer underwent this procedure from March 2014 to August 2015.

[The Comparison Between Extraction Methods of Exosomes From Ascites of Colorectal Cancer].

Objective: To compare the two different methods to isolate the exosome from the ascites of colorectal cancer (CRC) patient and find the efficient one.

Methods: Exosome from the ascites of CRC patient were isolated by two different methods: density gradient exosome isolation (DG-Exo) and Exo-Quick isolation, and followed by identification with transmission electron microscopy observation and Western blot analysis. And then, Nanodrop was used for protein quantification.

Unenhanced Computed Tomography to Visualize Hollow Viscera and/or Mesenteric Injury After Blunt Abdominal Trauma: A Single-Institution Experience.

To identify and describe the major features of unenhanced computed tomography (CT) images of blunt hollow viscera and/or mesenteric injury (BHVI/MI) and to determine the value of unenhanced CT in the diagnosis of BHVI/MI. This retrospective study included 151 patients who underwent unenhanced CT before laparotomy for blunt abdominal trauma between January 2011 and December 2013. According to surgical observations, patients were classified as having BHVI/MI (n = 73) or not (n = 78).

Transthoracic vs transhiatal surgery for cancer of the esophagogastric junction: a meta-analysis.

Aim: To compare the efficacy and safety of the transthoracic and transhiatal approaches for cancer of the esophagogastric junction.

Methods: An electronic and manual search of the literature was conducted in PubMed, EmBase and the Cochrane Library for articles published between March 1998 and January 2013. The pooled data included the following parameters: duration of surgical time, blood loss, dissected lymph nodes, hospital stay time, anastomotic leakage, pulmonary complications, cardiovascular complications, 30-d hospital mortality, and long-term survival.

Laparoscopic versus open hepatectomy with or without synchronous colectomy for colorectal liver metastasis: a meta-analysis.

Background: To compare short-term and long-term results of colorectal patients undergoing laparoscopic and open hepatectomy. Moreover, outcomes of laparoscopic versus open procedures for simultaneous primary colorectal tumor and liver metastasis resection were compared.

Methods: A systematic search was conducted in the PubMed and EmBase databases (until Oct.

Is Dor fundoplication optimum after laparoscopic Heller myotomy for achalasia? A meta-analysis.

Aim: To compare the outcome of acid reflux prevention by Dor fundoplication after laparoscopic Heller myotomy (LHM) for achalasia.

Methods: Electronic database PubMed, Ovid (Evidence-Based Medicine Reviews, EmBase and Ovid MEDLINE) and Cochrane Library were searched between January 1995 and September 2012. Bibliographic citation management software (EndNote X3) was used for extracted literature management.

Association between RAD51 gene polymorphism (-135G/C) and susceptibility of myelodysplastic syndrome and acute leukemia: evidence based on a meta-analysis.

Study results on the association between RAD51 gene -135G/C polymorphism and risk of myelodysplastic syndrome (MDS) or acute leukemia are inconsistent. A meta-analysis was conducted to identify the association. A systematic search was performed in PubMed, Embase, CNKI, VIP, Wanfang databases to collect all relevant studies until January 2013.

[Transabdominal and transhiatal esophagogastrostomy or esophagojejunostomy using novel double stapling technique].

Objective: To explore the techniques of esophagogastrostomy or esophagojejunostomy in the mediastinum through the abdomen and hiatus after extended proximal gastrectomy or total gastrectomy.

Methods: From May 2010 to January 2012, 15 patients with esophagogastric junction carcinoma underwent open transhiatal extended gastrostomy or total gastrectomy. After full mobilization, the anvil was reversely introduced into the esophagus and the esophagus was transected with curved stapler.
