Summer E Hanson, Matthew B Mitchell, Nihanth Palivela, S Andrew Peng, Lei Feng, Rene D Largo, Charles E Butler, Patrick B Garvey
BACKGROUND: Smaller anastomotic coupling devices may increase the risk of complications in free flap reconstructions; however, the relationship between coupler size and venous thrombosis rates has not been adequately evaluated. We hypothesized that smaller-diameter coupling devices are associated with higher rates of venous thrombosis than larger diameter devices in free tissue transfer. METHODS: We retrospectively reviewed data prospectively entered into a central departmental database for all patients who underwent microsurgical free tissue transfer at our institution in 2001-2013...

Davis G Taylor, John A Jane, Edward H Oldfield
OBJECTIVE Extracapsular resection of pituitary microadenomas improves remission rates, but the application of pseudocapsular techniques for macroadenomas has not been well described. In larger tumors, the extremely thin, compressed normal gland or its complete absence along the tumor's anterior surface limits the application of the traditional pseudocapsular technique that can be used for microadenomas. However, in the authors' experience, the interface between the pseudocapsule at the posterior margin of the adenoma and the compressed normal gland behind it is universally present, providing a surgical dissection plane...

BACKGROUND: The Japanese Classification of Gastric Carcinoma includes the left gastric artery (#7) lymph nodes (LNs) in the recommended extent of D1 LN dissection, but this recommendation has not been validated in western institutions. METHODS: We reviewed data from a prospectively maintained database of gastric cancer patients who underwent resection at our academic cancer center and had a separate pathologic assessment of #7 LN in 2005-2016. Risk factors for #7 LN metastases and overall survival were examined by uni- and multivariable analyses...

BACKGROUND: The creation of a diverting loop ileostomy is associated with the risk of readmission due to stoma-related complications. We hypothesized that the assessment of our institution-specific readmissions following ileostomy creation would help identifying at-risk groups which should be the focus of future preventative strategies. METHODS: Patients who underwent loop ileostomy formation from 2009 to 2013 were reviewed. We evaluated readmissions within 30 days after discharge following loop ileostomy construction...

Tricuspid valve disease has been neglected for a long time by cardiologists and surgeons, but for some years now leakage of tricuspid valve has been demonstrated as a prognostic factor in the evolution of patients with left heart valve disease undergoing surgery. Several techniques for plastic repair of tricuspid valve have been developed and the published studies differ on the results of these techniques; we conducted this study to assess the results of plastic repair of tricuspid valve in a population of patients with a high prevalence of rheumatic disease and to compare Carpentier's ring annuloplasty techniques with DEVEGA plasty...

BACKGROUND: Patients with secondary unilateral cleft lip are regularly affected by serious nasal deformities especially of the alar and nasal floor. A large number of techniques for correction have been published, but symmetrical restoration of severe nasal deformation is difficult to achieve. We propose an innovative approach for anatomical restoration for this entity of nasal deformities to achieve long-term symmetrical appearance and muscular function. METHODS: A total of 68 patients with severe nasal deformity due to secondary unilateral cleft lip underwent reconstructive surgery using a double composite tissue Z-plasty technique for anatomical restoration of cartilage, muscle, and soft tissue layers...
