Short- and Long-term Outcomes of Laparoscopic Total Mesenteric Excision for Neuroendocrine Tumors of the Rectum.

Background: To our knowledge, no studies to date have assessed the short- and long-term outcomes of laparoscopic total mesenteric excision in patients with neuroendocrine tumors of the rectum.

Objective: The purpose of this study was to investigate the short- and long-term outcomes of patients who underwent laparoscopic rectal resection plus total mesenteric excision for rectal neuroendocrine tumors at our institution.

Design: This was a single center, retrospective study.

Recurrent colorectal cancer after endoscopic resection when additional surgery was recommended.

Aim: To evaluate the type of recurrence after endoscopic resection in colorectal cancer patients and whether rescue was possible by salvage operation.

Methods: Among 4972 patients who underwent surgical resection at our institution for primary or recurrent colorectal cancers from January 2005 to February 2015, we experienced eight recurrent colorectal cancers after endoscopic resection when additional surgical resection was recommended.

Results: The recurrence patterns were: intramural local recurrence (five cases), regional lymph node recurrence (three cases), and associated with simultaneous distant metastasis (three cases).

The significance of extended lymphadenectomy for colorectal cancer with isolated synchronous extraregional lymph node metastasis.

Background/objective: The significance of extended lymphadenectomy for colorectal cancer with extraregional lymph node metastasis, such as para-aortic lymph node metastasis, has not been established. The purpose of this study was to evaluate the significance of extended lymphadenectomy for colorectal cancer with synchronous isolated extraregional lymph node metastasis.

Methods: Between July 2004 and December 2013, 16 patients with synchronous extraregional lymph node metastasis without other organ metastases underwent curative resection and extended lymphadenectomy (R0 group).

Surgery for synchronous colorectal cancers with double colonic anastomoses: A comparison of laparoscopic and open approaches.

Introduction: The aim of this study was to evaluate the safety of laparoscopic double colon resection and synchronous anastomosis for synchronous colorectal cancer.

Methods: We reviewed 42 consecutive patients who underwent double colon resection and synchronous anastomosis for synchronous colorectal cancer between 2000 and 2014. Clinical characteristics and short-term outcomes were compared between laparoscopic (n = 27) and open (n = 15) groups.

Clinicopathological features of gastric cancer in young patients.

Background: Early-onset gastric cancer is relatively rare. To evaluate the clinicopathological features and surgical outcome of young patients with gastric cancer, this retrospective comparative study was conducted.

Methods: From 2000 to 2010, 4882 patients underwent surgery for gastric adenocarcinoma in our institution.
