OBJECTIVE In this study, we evaluated the efficacy of dual-phase 3D CT angiography (CTA) during a single breath-hold using 16-MDCT in the assessment of vascular anatomy before laparoscopic gastrectomy. MATERIALS AND METHODS The study involved 20 consecutive patients (10 men, 10 women; mean age, 59 years) scheduled for laparoscopic gastrectomy for the(More)
BACKGROUND In laparoscopic operations for rectal carcinoma, only a few multicenter studies of a large number of patients have examined the impact of conversion on outcomes and determined risk factors for conversion. This study was designed to evaluate short-term outcomes and risk factors for conversion to open operation in laparoscopic operations for rectal(More)
BACKGROUND Because of the inability to palpate colonic tumors during laparoscopy, their location must be precisely identified before resection is undertaken. METHOD A retrospective study was performed of 58 patients in order to be able to describe our methods of tumor localization for laparoscopic colorectal operations and to review their effectiveness.(More)
BACKGROUND Hepatectomy is recommended as the most effective therapy for liver metastasis from colorectal cancer (CRCLM). It is crucial to elucidate the prognostic clinicopathological factors. METHODS Eighty-three patients undergoing initial hepatectomy for CRCLM were retrospectively analyzed with respect to characteristics of primary colorectal and(More)
BACKGROUND Laparoscopic gastrectomy has recently been gaining popularity as a treatment for cancer; however, little is known about the benefits of intracorporeal (IC) gastrointestinal anastomosis with pure laparoscopic distal gastrectomy (LDG) compared with extracorporeal (EC) anastomosis with laparoscopy-assisted distal gastrectomy (LADG). METHODS(More)
BACKGROUND The role of laparoscopic surgery in management of transverse and descending colon cancer remains controversial. The aim of the present study is to investigate the short-term and oncologic long-term outcomes associated with laparoscopic surgery for transverse and descending colon cancer. METHODS This cohort study analyzed 245 patients (stage II(More)
OBJECTIVE The impact of previous abdominal surgeries on the need for conversion to open surgery and on short-term outcomes during/after laparoscopic colectomy was retrospectively investigated. DESIGN This retrospective cohort study was conducted from December 1996 through December 2009. SETTING This study was conducted at Osaka Medical College Hospital.(More)
BACKGROUND Laparoscopic intersphincteric resection (Lap ISR) is not yet an established technique and its safety and feasibility are unclear. Our aim was to clarify the safety and feasibility of Lap ISR for clinical stage 0/I rectal cancer (Lap RC) in a prospective multicenter study of laparoscopic surgery in Japan. METHODS To examine the technical and(More)
BACKGROUND The aim of this study was to clarify the feasibility of laparoscopic surgery for rectal cancer retrospectively in 28 centers throughout Japan. METHODS Between May 1994 and February 2006, 1,057 selected patients with rectal cancer underwent laparoscopic surgery. All the data regarding the patient details, and operative and postoperative outcome(More)
BACKGROUND Laparoscopic low anterior resection for rectal cancer is considered to be more technically demanding than laparoscopic colectomy. This study aimed to analyze the learning curve for laparoscopic low anterior resection and to identify the factors that influence this learning curve. METHODS Data from 250 consecutive patients undergoing(More)
