Outcomes of laparoscopic tumor ablation for neuroendocrine liver metastases: a 20-year experience.

Background: Since neuroendocrine tumors have an indolent behavior, studies looking at oncologic outcomes should report a long-term follow-up. Over the years, we have been treating selected patients with neuroendocrine liver metastases (NELM) with laparoscopic ablation (LA) and reported favorable local tumor control. The aim of this study is to see whether this local efficacy translates into long-term oncologic outcomes.

Is it beneficial to use clinical scoring systems for acute appendicitis in adults?

Background: Clinical scoring systems have been used to reduce negative appendectomy rate for several decades. However, the use of these systems has been questioned due to differences in their diagnostic accuracies.

[Leriche syndrome].

Leriche syndrome is a disease characterized by thrombotic occlusion in the aorta, frequently in the distal renal artery. Classic symptoms of this syndrome include pain in the lower extremities emerging during activity (claudication), impalpability of femoral pulses, and impotency in male patients. Definitive diagnosis of claudication due to insufficient circulation as well as claudication that is neurogenic in origin, is difficult.

Mesh Inguinal Hernia Repair and Appendectomy in the Treatment of Amyand's Hernia with Non-Inflamed Appendices.

Amyand's hernia is defined as protrusion of the vermiform appendix in an inguinal hernia sac. It is a rare entity with variable clinical presentation from normal vermiform appendix to abscess formation due to perforation of acute appendicitis. Although surgical treatment includes appendectomy and hernia repair, appendectomy in the absence of an inflamed appendix and use of a mesh in cases of appendectomy remain to be controversial.
