Objectives: To evaluate the influence of the use of sodium fluorescein (FLS-Na) in surgery of glioblastoma (GB) on the degree of tumor resection and survival in patients treated at the National Institute of Neoplastic Diseases.
Materials And Methods: A total of 238 cases of GB treated between 2008 and 2013 were reviewed and 150 cases of GB who underwent surgical resection with clinicopathological information and adequate follow-up were selected.
Results: The mean age was 51 years, 58.7% of the cases presented a Karnofsky score of at least 90. FLS-Na was administered in 80 cases (53.3%) and a subtotal and total resection was obtained in 69 (46%) and 81 (54%) cases, respectively. The group that received FLS-Na obtained higher rates of total resection than the group operated with white light alone (77.5 vs 27.1%, p<0.001). The median overall survival (OS) was higher in the group subject to total compared to subtotal resection (17 vs 7 months, p<0.001). The median OS in those who received FLS-Na was higher than in those who did not (15.0 vs 8 months, p=0.003). Other factors affecting OS were age (p=0.002), the Karnofsky score (p=0.052) and radiation therapy (p=0.016) and chemotherapy (p=0.011).
Conclusions: The microsurgical technique with administration of FLS-Na was associated with an increase in the rate of total resection and survival.

Outcome of selective non-diverting low anterior resection after neoadjuvant chemoradiotherapy and curative surgery for proximal rectal cancer: A prospective case series.

Background: Low anterior resection (LAR) is the gold standard for curative cancer treatment in the middle and upper rectum. In radically operated patients, the local recurrence rates with total mesorectal excision (TME) after 5 and 10 years was<10%, with 80% in 5 years survival. Anastomotic leakage (AL) affects 4%-20% of patients who underwent LAR.

Epileptic spasms (ES) are a unique seizure type typically presenting in the form of infantile epileptic spasms syndrome (IESS) with characteristic hypsarrhythmia on scalp EEG and a preponderance with developmental delay or regression. While pharmacotherapy is the mainstay of treatment, surgical options, including disconnective or resective procedures, are increasingly recognized as viable therapeutic options for recurrent or persistent ES. However, limited data on safety, effectiveness, and prognostic factors hinder informed decision-making regarding surgery indications, timing, and intervention type.

Flurbiprofen axetil is a nonsteroidal anti-inflammatory drug used for analgesia. Its combination with dezocine has previously shown a superior postoperative analgesic effect compared with that of opioids. The present study compared the analgesic effect between dezocine plus flurbiprofen axetil (DFA) and sufentanil in patients with colorectal cancer (CRC) following resection of the tumor.

Objective: Extant imaging methods used for the proper identification of the parathyroid glands to prevent post-operative hypothyroidism associated with the resection of differentiated thyroid cancer (DTC) are limited by factors such as low specificity, high cost, and technical complexity. This study, therefore, sought to investigate the efficacy of the immunocolloidal gold strip method combined with nanocarbon negative imaging tracing technology for parathyroid gland imaging during radical resection of DTC in elderly patients.
Methods: A total of 100 elderly patients with DTC were enrolled and randomly divided into two groups: the control group and the observation group.

Introduction: Nonfunctioning pancreatic neuroendocrine tumors (NF-PNETs) have been diagnosed increasingly often but still represent rare pancreatic neoplasms. Surgery is a potentially curative approach for patients with NF-PNETs. In recent years, minimally invasive surgery (MIS) has been applied more frequently for surgical resection of NF-PNETs.
