Article Synopsis
- The study examines differences in presentation and outcomes between patients with incidental gallbladder carcinoma (GBC) and those with suspected GBC, finding that over half of GBC cases are discovered incidentally.
- Out of 571 patients analyzed, 22.4% had preoperative suspicion of malignancy, while 77.6% were found incidentally; incidentally discovered tumors were generally smaller, better differentiated, and less likely to have metastasized.
- The median survival rate for incidentally discovered GBC was significantly better at 32.3 months compared to 5.8 months for suspected GBC, highlighting that preoperative suspicion is a significant risk factor for worse outcomes.
Aim: To assess whether the use of fibrin sealant shortens the closure time of postoperative enterocutaneous fistulas (ECFs).
Methods: The prospective case-control study included 70 patients with postoperative ECFs with an output of < 500 mL/d, a fistulous tract of > 2 cm and without any local complication. They were divided into study (n = 23) and control groups (n = 47).
Objective: We undertook this study to determine the relationship between clinical symptoms as predictors for staging colorectal cancer (CRC).
Methods: We performed a cross-sectional study from January 2000 to January 2005 at the "Hospital Civil Fray Antonio Alcalde." All patients with histological diagnosis of CRC were included.
Introduction: Urethrocutaneous fistulas (UCF) and flap dehiscence (FD) are the most common postoperative complications after hypospadias (HS) surgical repair. The aim of this study was to evaluate whether the application of fibrin sealant over the site of surgery and suture lines reduces these complications.
Materials And Methods: A prospective cohort of consecutive patients was treated over a 3-year period.
Background: The presentation of heart tumors is very uncommon. Eighty percent of primary heart neoplasias are benign, and myxomas represent the first cause in frequency among adult populations. Due to the frequency of presentation of these tumors, it is common to make the clinical/surgical diagnosis without obtaining histopathologic confirmation.

An increase in its presentation has been seen due to certain pathologies or clinical conditions associated with immune suppression, endocarditis being one of the most frequent causes. Gram-positive aerobes are the main causal agents with non-specific clinical manifestations.

Introduction: Ulcerative colitis (UC) is a disease characterized by relapsing and remitting non-infectious inflammation of the colorectal mucosa. Its heterogeneity makes assessment of the disease's activity a prerequisite for a rational choice of therapy. We aimed to determine sensitivity, specificity, positive and negative predictive values of hemoglobin, hematocrit, and platelets to develop a simplified activity index of UC.

Material And Methods: A total of 43 women treated surgically were randomly assigned to receive 10 ml of fibrin glue at the end of the breast resection plus closed suction drains (n = 22), or drain system only as a control group (n = 23). Outcome variables were fluid collected in the drainage system measured each 24 h.
