Primary Squamous Cell Carcinoma of the Remnant Stomach after Subtotal Gastrectomy.

Primary squamous cell carcinoma (SCC) of the stomach is a very rare disease. However, the pathogenesis, clinical characteristics, and prognosis of gastric SCC are controversial and remain to be elucidated. Herein, we report a case of primary gastric SCC of the remnant stomach after subtotal gastrectomy.

Comparison of the outcomes of laparoscopic and open approaches in the treatment of periappendiceal abscess diagnosed by radiologic investigation.

Background: Although laparoscopic appendectomy (LA) has been performed widely, the role of LA for complicated appendicitis remains controversial, and its role for periappendiceal abscess (PA) remains undefined. This study compared the clinical outcomes of LA and open appendectomy (OA) for PA diagnosed by radiologic investigation.

Patients And Methods: We conducted a retrospective review of 84 patients who underwent surgery for PA diagnosed by radiologic investigation between 2010 and 2013.

Clinical characteristics of acute appendiceal diverticulitis.

Purpose: Diverticulitis of vermiform appendix is known as a rare cause of acute appendicitis, most of which are diagnosed after surgery. We compared appendiceal diverticulitis with acute appendicitis to study the clinical characteristics of appendiceal diverticulitis.

Methods: Among 1,029 patients who received appendectomy from January 2009 to May 2011, 38 patients with appendiceal diverticulitis (diverticulitis group) were compared with 98 randomly collected patients with acute appendicitis (appendicitis group) during the same period.
