BACKGROUND The effect of obesity on gastrectomy in patients with gastric cancer is controversial. The degree of abdominal fat increases the technical difficulty of abdominal surgery. This study examined the effect of visceral fat on total gastrectomy and risk factors associated with the formation of pancreatic fistula. METHODS Between February 2001 and(More)
BACKGROUND The clinical value of synbiotics in patients undergoing esophagectomy remains unclear. This study investigated the effects of synbiotics on intestinal microflora and surgical outcomes in a clinical setting. METHODS We studied 70 patients with esophageal cancer who were scheduled to undergo esophagectomy. They were randomly allocated to 2(More)
Gastro-tracheobronchial fistula (GTF) is a rare but life-threatening complication specifically observed after esophagectomy and reconstruction using posterior mediastinal gastric tube. Ten cases of GTF were encountered in three hospitals in 2000-2009. Their clinicopathological, surgical, and postoperative care are summarized, together with a review of(More)
BACKGROUND Esophagectomy remains the mainstay treatment for clinical T1bN0M0 esophageal cancer because pathologic lymph node metastases in these patients are not negligible. Recently, chemoradiotherapy (CRT), which can preserve the esophagus, has been reported to be a promising therapeutic alternative to esophagectomy. However, to our knowledge, no(More)
BACKGROUND This study evaluated the usefulness of photodynamic diagnosis (PDD) using oral 5-aminolevulinic acid (ALA) for the detection of peritoneal metastases in advanced gastric cancer. METHOD First, the numbers of peritoneal metastatic nodules that were visible under conventional white light (WL) and ALA-induced fluorescence (ALA-F) were quantified in(More)
BACKGROUND Pancreatic fistula (PF) is a common complication after pancreatectomy. Previous reports indicate that preoperative irradiation decreases the risk of PF after pancreatoduodenectomy. In this context, the impact of preoperative chemoradiation therapy (CRT) on PF formation after distal pancreatectomy is of interest. METHODS Fifty-eight patients(More)
BACKGROUND A lateral pelvic lymph node dissection (LPLD) for lower rectal cancer may be beneficial for a limited number of patients. If sentinel node (SN) navigation surgery could be applied to lower rectal cancer, then unnecessary LPLDs could be avoided. The aim of this study was to investigate the feasibility of lateral region SN biopsy by means of(More)
OBJECTIVE Esophageal squamous cell carcinoma (ESCC) is refractory to current therapeutic regimens and more effective therapies are imperative. To this end, we conducted a multicenter phase I/II trial of docetaxel, cisplatin, and fluorouracil (DCF) combination chemotherapy for ESCC. METHODS The study subjects were 46 patients with advanced or recurrent(More)
OBJECTS Recently, we reported that diagnostic laparoscopy with photodynamic diagnosis using oral 5-aminolevulinic acid (ALA-PDD) is a promising tool for diagnosing early peritoneal metastases in gastric cancer. The present study evaluated the usefulness of adding ALA-PDD to conventional diagnostic laparoscopy and assessed the association of the ALA-PDD(More)
