OBJECTIVE The aim of this study was designed to determine whether the period of drain insertion influences the incidence of postoperative complications. BACKGROUND DATA The significance of prophylactic drains after pancreatic head resection is still controversial. No report discusses the association of the period of drain insertion and postoperative(More)
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. This cohort study analyzed 245 patients (stage II disease, n = 70;(More)
The efficacy and safety outcomes of laparoscopy-assisted distal gastrectomy (LADG) with D2 lymph node dissection for locally advanced gastric cancer remain unclear. Therefore, we conducted a randomized, controlled phase II trial to confirm the feasibility of LADG in terms of technical safety, and short-term surgical outcomes were investigated. Eligibility(More)
OBJECTIVE To determine if an antecolic or a retrocolic duodenojejunostomy during pylorus-preserving pancreaticoduodenectomy (PpPD) was associated with the least incidence of delayed gastric emptying (DGE), in a prospective, randomized, controlled trial. SUMMARY BACKGROUND DATA The pathogenesis of DGE after PpPD has been speculated to be related to factors(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)
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 For early gastric cancer located in the upper third of the stomach, we have adopted laparoscopic 1/2-proximal gastrectomy (PG) with two types of reconstruction: double tract reconstruction (L-DT) and jejunal interposition reconstruction with crimping of the jejunum on the anal side of the jejunogastrostomy with a knifeless linear stapler (L-JIP).(More)
INTRODUCTION AND AIMS The survival of pancreatic cancer patients with portal vein resection is extremely poor due to the high incidence of liver metastasis. The occurrence of liver metastasis is decreased by locoregional arterial infusion after pancreatic surgery. Chemosensitivity tests can provide the basis for individualized chemotherapy in each patient(More)
OBJECTIVE This study was conducted to examine the long-term prognosis of after treatment of patients with choledocholithiasis, including the recurrence of lithiasis, and to thereby determine the best treatment modality for choledocholithiasis based on its pathological entity. SUMMARY BACKGROUND DATA Choledocholithiasis can be caused by either primary bile(More)
BACKGROUND/PURPOSE The aim of this study was to clarify the prognostic factors of intrahepatic cholangiocarcinoma (ICC) following hepatectomy and to examine the impact of lymph node metastasis on survival. This study was therefore carried out as a Project Study of the Japanese Society of Hepato-Biliary-Pancreatic Surgery. METHODS Three hundred and(More)
