Purpose: We investigated the prognostic significance of postoperative infections for the outcome of 192 patients with colon cancer.
Methods: The 5-year survival rates were analyzed by the Kaplan-Meier technique. Univariate and multivariate analyses were done to evaluate prognostic variables using Cox's proportional hazard model.
Results: Forty-three patients developed deep incisional or organ/space surgical site infections. The groups with and without infection were comparable. Multivariate analysis showed that only Dukes' stage (p=0.048) and postoperative infection (p=0.011) were independently associated with outcome. In patients with infective complications, the survival rate was significantly lower than in subjects without infection (log rank p=0.0004).
Conclusions: These results stress the importance of evaluating variables other than the classical tumor stage in predicting long-term cancer outcome.

Background: Direct-to-implant (DTI) breast reconstruction offers immediate aesthetic and psychological benefits, but the role of acellular dermal matrix (ADM) remains debated. Using a multi-institutional database, this study evaluates and compares outcomes between ADM-assisted and non-ADM DTI procedures.
Methods: The American College of Surgeons National Surgical Quality Improvement Program database from 2008 to 2022 was queried to identify female patients who underwent DTI breast reconstruction for oncological purposes.

Background: One-stage direct-to-implant (DTI) breast reconstruction is increasingly popular with the use of prepectoral reconstruction leading to increased demand for structural scaffolds. It is vital to determine if differences in safety profiles exist among scaffolds.
Methods: We performed a retrospective cohort study of consecutive patients in our breast cancer center undergoing DTI reconstruction.

Objective: The relationship among body mass index (BMI), postoperative complications, and clinical outcomes in patients undergoing gastrectomy for gastric cancer remains unclear. This study aimed to evaluate this association using a meta-analysis.
Method: We conducted a systematic search of the PubMed, Embase, and Cochrane Library databases up to February 25, 2024.
Unicoronal synostosis is a rare condition leading to anterior plagiocephaly with facial scoliosis and deformation of the anterior cranial fossa. Fronto-orbital advancement and remodelling (FOAR) is the standard of care for management, aiming to normalise the brow shape and position while ameliorating the risk of raised intracranial pressure (ICP) throughout childhood. Published long-term surgical outcome data for unicoronal synostosis is lacking.

Background: We sought to determine the wound complications associated with a straight midline incision overlying the Achilles tendon. Data on sex, age, body mass index (BMI), surgery performed, date of surgery, and wound development were collected.
Methods: We retrospectively collected data on 217 patients with a mean ± SD age of 46.
