Is Percutaneous Transhepatic Biliary Drainage Better than Endoscopic Drainage in the Management of Jaundiced Patients Awaiting Pancreaticoduodenectomy? A Systematic Review and Meta-analysis.

Purpose: To compare postoperative complications in patients who underwent pancreatoduodenectomy after either endoscopic or percutaneous biliary drain (BD).

Material And Methods: Data from studies comparing the rate of postoperative complications in patients who underwent endoscopic BD or percutaneous BD before pancreatoduodenectomy were extracted independently by 2 investigators. The primary outcome compared in the meta-analysis was the risk of postoperative complications.

Does neoadjuvant doxorubicin drug-eluting bead transarterial chemoembolization improve survival in patients undergoing liver transplant for hepatocellular carcinoma?

Purpose: We aimed to compare the overall (OS) and disease-free survival (DFS) of patients undergoing orthotopic liver transplant (OLT) for hepatocellular carcinoma who did and did not have neoadjuvant doxorubicin drug-eluting bead transarterial chemoembolization (DEB-TACE).

Methods: This is a retrospective study of 94 patients with HCC transplanted between 2000 and 2014 in a single tertiary center. Pre- and postoperative features, DFS and OS were compared between patients who received pre-OLT DEB-TACE (n=34, DEB-TACE group) and those who did not (n=60, non-TACE group).

Completion Proctectomy for Crohn's Colitis: Lessons Learned.

Surgical management of Crohn's disease is reserved for patients refractory to medical therapy and those who develop complications alleviated by surgery. Surgical resection may be the most efficient way to restore health in patients with stricturing and or fistulizing disease of the terminal ileum / small bowel. However, decision-making in patients with Crohn's colitis is more difficult.

Total hepatectomy and liver transplantation as a two-stage procedure for fulminant hepatic failure: A safe procedure in exceptional circumstances.

Aim: To evaluate the outcomes of two-stage liver transplant at a single institution, between 1993 and March 2015.

Methods: We reviewed our institutional experience with emergency hepatectomy followed by transplantation for fulminant liver failure over a twenty-year period. A retrospective review of a prospectively maintained liver transplant database was undertaken at a national liver transplant centre.

Awareness and uptake of family screening in patients diagnosed with colorectal cancer at a young age.

Background. One-fifth of people who develop colorectal cancer (CRC) have a first-degree relative (FDR) also affected. There is a large disparity in guidelines for screening of relatives of patients with CRC.

Early recurrence and progression of a rare rectal squamous cell carcinoma after initial response to primary chemoradiotherapy.

Rectal squamous cell carcinomas represent an extremely rare malignancy which carries a significant morbidity and mortality. Diagnosis requires distinction from squamous cell carcinoma of the anus and colonic adenocarcinoma by endoscopy and histopathological examination of a biopsy. Due to the rarity of the pathology, available evidence is limited and optimum management has yet to be elucidated.

Impact of mesenchymal stem cell secreted PAI-1 on colon cancer cell migration and proliferation.

Mesenchymal Stem Cells are known to engraft and integrate into the architecture of colorectal tumours, with little known regarding their fate following engraftment. This study aimed to investigate mediators of Mesenchymal Stem Cell (MSC) and colon cancer cell (CCC) interactions. Mesenchymal Stem Cells and colon cancer cells (HT29 and HCT-116) were cultured individually or in co-culture on 3-dimensional scaffolds.

A nodal positivity constant: new perspectives in lymph node evaluation and colorectal cancer.

Purpose: To date, associations between the number of lymph nodes evaluated, staging, and survival have been examined in the context of large population-based studies conducted by a small number of investigators. Therefore, although high-quality data are available, perspective is lacking.

Methods: Studies for this paper were identified by searches of Medline, Scopus, PubMed, and manual searching of references from articles, using the search terms ''colorectal cancer'', ''nodal status'' and ''lymph node''.

Heterotopic ossification of the abdominal wall.

Introduction: Heterotopic ossification is a rare, benign condition which occurs when bone develops in tissues that do not normally ossify.

Presentation Of Case: We herein report the case of a 73-year-old gentleman who underwent a laparotomy for a large splenic flexure tumour considered unresectable at initial intervention. Following delivery of chemotherapy, he was referred for a second opinion and the tumour with adjacent structures was removed at a subsequent laparotomy.

Surgical management of locally recurrent rectal cancer.

Developments in chemotherapeutic strategies and surgical technique have led to improved loco regional control of rectal cancer and a decrease in recurrence rates over time. However, locally recurrent rectal cancer continues to present considerable technical challenges and results in significant morbidity and mortality. Surgery remains the only therapy with curative potential.

Mesenchymal stem cells in the colorectal tumor microenvironment: recent progress and implications.

Mesenchymal stem cells (MSCs) are nonhematopoietic multipotent adult stem cells. They have been shown to have a natural tropism for many tumors types, including colorectal, and are capable of escaping host immune surveillance. MSCs are known to engraft at tumors and integrate into their architecture, potentially as carcinoma-associated fibroblasts.
