Introduction-The Joint Commission Surgical Care Improvement Project (SCIP) includes performance measures aimed at reducing surgical site infections (SSI). One measure defines approved perioperative antibiotics for general operative procedures. However, there may be a subset of procedures not adequately covered with the use of approved antibiotics. We hypothesized that piperacillin-tazobactam is a more appropriate perioperative antibiotic for pancreaticoduodenectomy (PD).

Histopathologic phenotype is a better prognosticator of survival in patients with periampullary adenocarcinomas than tumor anatomic location. Those with PB-type duodenal, ampullary, or distal CBD adenocarcinomas have survival similar to those with PDAC.

Background: The treatment of type 1 Chiari malformation (CM-1) with posterior fossa decompression without (PFD) or with duraplasty (PFDD) is controversial. The authors analyze both options in a national sample of pediatric patients. Methods: Utilizing the Kids' Inpatient Database, CM-1 patients undergoing PFD or PFDD from 2000 through 2009 were analyzed. Results: 1,593 patients with PFD and 1,056 with PFDD were evaluated. The average age was 10.3 years, slightly younger in PFD (9.8 vs. 10.9 years, p = 0.001). PFDD patients were more likely White (81.2 vs 75.6%, p = 0.04) and less likely admitted emergently (8.4 vs. 13.8%, p = 0.007). They also underwent more reoperations (2.1 vs. 0.7%, p = 0.01), had more procedure-related complications (2.3 vs. 0.8%, p = 0.003), a longer length of stay (4.4 vs. 3.8 days, p = 0.001) and higher charges (USD 35,321 vs. 31,483, p = 0.01). Conclusions: This large national study indicates that PFDD is performed more often in Caucasians, less so emergently, and associated with significantly more complications and immediate reoperations, while PFD is more frequent in those with syringomyelia and more economical, requiring fewer hospital resources. Overall, PFD is more favorable for CM-1, though it would be prudent to conduct a prospective trial, as this analysis is limited by data on preoperative presentations and long-term outcomes.

Our approach to patients with LA/BR PDAC, which includes prolonged preoperative chemotherapy, is associated with a high incidence of LN-negative disease and excellent OS. After surgical resection, HP treatment response, perineural invasion, and SMAD4 status should help determine who should receive adjuvant therapy in this select subset of patients.

Oesophageal self-dilation is an effective way of maintaining oesophageal patency in refractory benign oesophageal strictures, with safety comparable to current standard of care. Prospective studies are needed to further validate the role of self-dilation in treatment of refractory benign oesophageal strictures.

SUMMARY BackgroundOesophageal lichen planus is an idiopathic inflammatory disorder characterized by significant oesophageal stricturing. Oesophageal lichen planus is a rare, difficult to diagnose, and likely an under recognized disease. As a result, there is no standardized approach to therapy and treatment strategies vary.
