Background: A Billroth I reconstruction with a mechanically sutured anastomosis is commonly performed in gastric cancer patients. Some surgeons prefer to use large circular staplers during suturing to minimize risks for anastomotic stricture and gastric stasis after surgery. The effect of stapler size on anastomotic complications has not been validated.

Methods: From January 2008 through June 2008, 669 patients who underwent curative gastrectomy for gastric cancer were included in a retrospective study. Medical records of consecutive patients were collected and analyzed to determine postoperative wound complication rates.
Purpose: The incidence of lymph node metastasis has been reported to range from 2.6 to 4.8% in early stage gastric cancer with mucosal invasion (T1a cancer).

Methodology: Sixty-one consecutive patients with upper third early gastric cancer that underwent radical total gastrectomy from May 2009 to December 2009 were included in this prospective cohort study. Patients were stratified by BMI (in accordance with the WHO guidelines) into a normal group (18.
Background And Objectives: The purpose of the present study was to investigate clinicopathologic features of gastric cancer patients with only positive peritoneal cytology in the absence of overt peritoneal metastases, and which might distinguish patients with poorer prognosis.
Methods: Between September 1994 and August 2006, clinicopathological features were retrospectively evaluated in 37 consecutive patients with gastric cancer who underwent a curative resection and had positive peritoneal cytology in the absence of overt peritoneal metastases. Survival including disease-free survival (DFS) and overall survival (OS), and recurrence patterns were analyzed according to clinicopathologic characteristics.
Background And Objectives: The seventh edition of the AJCC has more detailed staging categories for gastric cancer than does the sixth edition. The aim of our study was to compare the prognostic accuracies of the sixth and seventh AJCC editions for gastric cancer patients.
Methods: We analyzed survival rates by category using the sixth and seventh editions of the AJCC in 10,060 patients with gastric cancer who had undergone gastrectomy between 1994 and 2007 at Samsung Medical Center.
Background And Objectives: The correlation between perioperative CEA, CA 19-9, and CA 72-4 and recurrence of gastric cancer has not been clarified. The aim of this study was to investigate the relationships between perioperative CEA, CA 19-9, and CA 72-4 and recurrence of gastric cancer.
Methods: We retrospectively analyzed the relationships between the tumor markers CEA, CA 19-9, and CA 72-4 and recurrence of gastric cancer.
The circular stapling technique has been widely applied for gastrointestinal anastomosis in gastrectomies (open or laparoscopic) for distal gastric cancers. We describe this method for use in performing Billroth II anastomosis in distal gastrectomies. From 2002-2009, we report the results following the use of the circular stapling technique performed in 520 patients at a single institution.

December 2008
Aim: To analyze the risk factors of pancreatic leakage after pancreaticoduodenectomy.
Methods: We retrospectively reviewed 172 consecutive patients who had undergone pancreatico-duodenectomy at Inha University Hospital between April 1996 and March 2006. We analyzed the pancreatic fistula rate according to the clinical characteristics, the pathologic and laboratory findings, and the anastomotic methods.
