Comparative Study Clinical Trial
A comparative study on comprehensive, objective outcomes of laparoscopic Heller myotomy with per-oral endoscopic myotomy (POEM) for achalasia.
To compare symptomatic and objective outcomes between HM and POEM. ⋯ POEM is an endoscopic therapy for achalasia with a shorter hospitalization than HM. Patient symptoms and esophageal physiology are improved equally with both procedures. Postoperative esophageal acid exposure is the same for both. The POEM is comparable with laparoscopic HM for safe and effective treatment of achalasia.

This study hypothesized that tumor size, number of tumors, surgical approach, and tumor histology significantly affected microwave ablation (MWA) success and recurrence-free survival. ⋯ In this large data set, patients with 3 cm or more tumors showed a propensity for early recurrence, regardless of histology. Higher rates of local recurrence were noted in HCC patients, which may reflect underlying liver disease. There were no significant differences in morbidity or survival based on the surgical approach; however, local recurrence rates were highest for percutaneously ablated tumors.

Observational Study
The clinical utility of the combination of T stage and venous invasion to predict survival in patients undergoing surgery for colorectal cancer.
To examine the clinical utility of improved detection of venous invasion (VI) in patients undergoing potentially curative resection of colorectal cancer. ⋯ The results of the present study have prompted the development of a novel tumor staging system based on TVI. The TVI has clinical utility, especially in node-negative disease, in predicting outcome following curative resection for CRC.

Born in the early 20th century, the Vietnamese surgeon Ton That Tung received his medical education in French colonial Indochina at the fledgling l'Ecole de Médecine de Hanoi, the first indigenous medical school in Southeast Asia. The benefactor of a postgraduate position at the medical school, Ton That Tung subsequently obtained his surgical training at the Phù Doãn Hospital in Hanoi and concurrently developed a passion for the study of liver anatomy, pathology, and surgery. ⋯ Nevertheless, Ton That Tung remains a pioneer in liver anatomy and liver surgery. His commitment to surgical science and, more importantly, to the Vietnamese people stands as a tribute to the tireless pursuit of his ideals.

Postoperative cognitive decline is emerging as a significant complication of surgery among older adults. Animal models indicate a central role of hippocampal inflammatory responses in the pathophysiology of postoperative cognitive decline. We hypothesized that atorvastatin, shown to exert neuroprotective potential in central nervous system (CNS) disorders, would attenuate neuroinflammation and improve cognitive function in mice after surgery and anesthesia. ⋯ These findings indicate that cognitive decline is very likely associated with synaptic pathology after systemic and central inflammation induced by peripheral surgery/isoflurane anesthesia and suggest that the anti-inflammatory and neuroprotective properties of atorvastatin provide a rationale for its use as a therapeutic strategy for postoperative cognitive decline.
