Infliximab increases the risk of postoperative complications after restorative proctocolectomy and has altered the surgical approach to ulcerative colitis. Potential benefits of infliximab should be balanced against these risks.

The X-ray repair cross-complementing group 1 (XRCC1) and xeroderma pigmentosum group D (XPD) genes are involved in base excision repair and nucleotide excision repair of DNA repair pathways, respectively. A growing body of evidence suggests that XRCC1 and XPD are important in environmentally induced cancers, and polymorphisms in both genes have been identified. To determine whether the XRCC1 (codon Arg399Gln) and XPD (codon Asp312Asn and codon Lys751Gln) polymorphisms are associated with prostate cancer susceptibility, we genotyped these polymorphisms in a primarily Caucasian sample of 506 sibships (n ‫؍‬ 1,117) ascertained through a brother with prostate cancer. Sibships were analyzed with a Cox proportional hazards model with age at prostate cancer diagnosis as the outcome. Of the three polymorphisms investigated, only the XPD codon 312 Asn/Asn genotype had an odds ratio (OR) significantly different from one (OR, 1.61; 95% CI, 1.03-2.53). Analyses stratified by the clinical characteristics of affected brothers in the sibship did not reveal any significant heterogeneity in risk. In exploring two-way gene interactions, we found a markedly elevated risk for the combination of the XPD codon 312 Asn/Asn and XRCC1 codon 399 Gln/Gln genotypes (OR, 4.81; 95% CI, 1.66 -13.97). In summary, our results suggest that the XPD codon 312 Asn allele may exert a modest positive effect on prostate cancer risk when two copies of the allele are present, and this effect is enhanced by the XRCC codon 399 Gln allele in its recessive state.

An interval between chemoradiation and surgery ≥ 8 weeks is safe and is associated with a higher rate of pathologic complete response and decreased local recurrence.

Achievement of pCR after neoadjuvant chemoradiation is associated with greatly improved cancer outcomes in locally advanced rectal cancer. Future studies should evaluate the relationship between increases in pCR rates and improvements in cancer outcomes in this population.

In selected patients with ulcerative colitis IRA gives an acceptable quality of life and functional outcome that are comparable to those in patients with an IPAA. Owing to the risk of cancer, surveillance of the rectum is mandatory.

CTE is an accurate preoperative diagnostic imaging study for small-bowel Crohn's disease. The ability of this imaging study to detect both luminal and extraluminal pathology is a distinct advantage of CTE compared with small-bowel contrast studies.

Effective postsurgical analgesia is a critical aspect of patient recovery. The goal of this prospective, randomized, controlled, blinded study was to examine the effect that liposomal bupivacaine delivered by means of a transversus abdominis plane block has on pain control in women undergoing unilateral deep inferior epigastric perforator flap reconstruction. Institutional review board approval was granted for this prospective study. Patients were eligible if they were undergoing unilateral, delayed deep inferior epigastric perforator flap reconstruction. Patients were randomized to one of three groups: liposomal bupivacaine transversus abdominis plane block, or bupivacaine pain pump. Charts were reviewed for demographics, length of stay, and postoperative narcotic use. There were eight patients in the liposomal bupivacaine and bupivacaine transversus abdominis plane block groups and five patients in the pain pump group. A retrospective cohort of six patients who did not receive any intervention was included. Patients who received a liposomal bupivacaine transversus abdominis plane block used statistically significantly less intravenous and total postoperative narcotics in milligrams and milligrams per kilogram per day compared with all other cohorts. They were able to get out of bed at an earlier time point. Overall hospital costs were similar among the groups. This is the first study to investigate liposomal bupivacaine delivered as a transversus abdominis plane block in a prospective, randomized, blinded study in women undergoing unilateral, delayed, abdominally based autologous breast reconstruction. The authors were able to demonstrate a significant reduction in intravenous and total narcotic use when a liposomal bupivacaine transversus abdominis plane block was used. Future studies are needed to prospectively investigate the effect that liposomal bupivacaine would have on immediate and bilateral reconstructions.

Colon surgery for familial adenomatous polyposis has evolved as advances in surgical technique have created more options to reduce the risk of cancer. Current strategy uses polyposis severity and distribution to decide on the surgical option, and laparoscopy to minimize morbidity.
