Short- and long-term outcomes following pelvic exenteration for gynae-oncological and colorectal cancers: A 9 year consecutive single-centre cohort study.

Objectives: Radical pelvic exenteration can be undertaken for locally invasive or recurrent disease in both colorectal and gynaecological malignancies. In the UK this procedure is usually undertaken by the respective surgical specialties who have undergone divergent surgical training. This study describes and compares outcomes between colorectal and gynae-oncological teams following pelvic exenteration for primary and recurrent gynaecological and colorectal cancers in a single-centre multi-disciplinary team.

The novel appearance of low rectal anastomosis on contrast enema following laparoscopic anterior resection: discriminating anastomotic leaks from "dog-ears" on water-soluble contrast enema and flexible sigmoidoscopy.

Purpose: Interpretation of water-soluble contrast enema following laparoscopic low anterior resection can be very challenging for both radiologists and colorectal surgeons. Discriminating the radiological appearances secondary to anastomotic configuration from those caused by actual anastomotic dehiscence is a common problem and may be made worse with the advent of laparoscopic surgery. The aim of this study is to identify potential novel appearances of the water-soluble contrast enema (WSCE) images of rectal anastomosis following laparoscopic low anterior resection to radiologists and surgeons.

Longterm -ostomy as a quality marker: Comparison of outcomes from a six year series of laparoscopic surgery in MRI defined low rectal cancer.

Aim: We propose long-term -ostomy rate following laparoscopic rectal cancer resection must be included as an overall quality indicator of treatment in conjunction with frequently reported and readily available end points.

Method: A database was collated prospectively of consecutive rectal cancer resections over a 6-year period. Recorded data included pre-operative MRI (tumour stage and height from the anal-verge), as well as demographics, treatment, local recurrence rate, survival and -ostomy rate as the primary outcome measure.

Covered metallic stents for the palliation of colovesical fistula.

Colovesical fistula is a distressing condition that is usually managed surgically. For some patients in whom surgery is not feasible, covered colonic stents offer palliation. We present two challenging cases with contrasting outcomes.

Genetic variants in XRCC2: new insights into colorectal cancer tumorigenesis.

Polymorphisms in DNA double-strand break repair gene XRCC2 may play an important role in colorectal cancer etiology, specifically in disease subtypes. Associations of XRCC2 variants and colorectal cancer were investigated by tumor site and tumor instability status in a four-center collaboration including three U.K.

Meta association of colorectal cancer confirms risk alleles at 8q24 and 18q21.

Background: Genome-wide association studies of colorectal cancer (CRC) have identified genetic variants that reproducibly associate with CRC. Associations of 12 single nucleotide polymorphisms at 8q24, 9p24, and 18q21 (SMAD7) and CRC were investigated in a three-center collaborative study including two U.K.

MLH1 -93G>A promoter polymorphism and risk of mismatch repair deficient colorectal cancer.

Rare inherited mutations in the mutL homolog 1 (MLH1) DNA mismatch repair gene can confer an increased susceptibility to colorectal cancer (CRC) with high penetrance where disease frequently develops in the proximal colon. The core promoter of MLH1 contains a common single nucleotide polymorphism (SNP) (-93G>A, dbSNP ID:rs1800734) located in a region essential for maximum transcriptional activity. We used logistic regression analysis to examine the association between this variant and risk of CRC in patients in the United Kingdom.

Intermittent torsion of a megapouch: report of a case.

We report an unusual presentation of pouch dysfunction because of excessive pouch enlargement or "mega pouch" and probable torsion. The patient presented with abdominal pain that was positional. Contrast-enhanced computerized tomography showed pouch anastomotic staples extending into the right upper quadrant.

Nicorandil and idiopathic anal ulceration.

Purpose: Several reports have implicated nicorandil as a reversible cause of anal ulceration. We have recently commenced a specialist clinic for patients presenting with severe anal ulceration to assess treatment in this difficult group. Recognition of this association may avoid unnecessary surgery.
