Anastomotic leakage is one of the most serious complications following laparoscopic low anterior resection (LAR) for rectal cancers. The purpose of this study was to investigate whether transanal tube placement can reduce anastomotic leakage following laparoscopic LAR. Retrospective assessment was performed on 205 patients with rectal cancers who underwent(More)
Background. Standard treatment of early gastric cancer (EGC) after endoscopic resection with risk factors of nodal metastases and incomplete resection is controversial. We investigated optimal management for the patients with potentially noncurative EGC after endoscopic resection. Methods. We retrospectively examined clinicopathological data and surgical(More)
Although laparoscopic surgery is frequently performed for the treatment of gastric cancer, laparoscopic total gastrectomy is not widely performed because of its technical difficulty. Since December 2007 we have performed esophagojejunostomy after totally laparoscopic total gastrectomy (TLTG) in more than 110 cases in our institution by using a circular(More)
BACKGROUND We report an extremely rare case of resection of localized biphasic malignant peritoneal mesothelioma of the transverse colon. CASE REPORT Computed tomography and magnetic resonance imaging in a 72-year-old man showed a tumor with enhanced borders consistent with the transverse colon. Colonoscopy showed ulcerative lesions in the transverse(More)
In this study, we demonstrated the complete resection of untinate process that was performed by the hybrid laparoscopic surgery using our original new technique of Shuriken shaped umbilicoplasty with sliding window`s method. A 70-year-old weman was hospitalized for surgery of intraductal papillary mucinous neoplasm located in the uncinate process of(More)
BACKGROUND In this study, we demonstrated our new device for open donor liver surgery with left-sided heptectomy by use of the real-time moving windows (RTMW) method with 8-cm transverse skin incision for living donors from the viewpoints of cosmetic, economic, and safety procedures. METHODS After the upper abdominal 8-cm transverse skin incision was(More)
The rupture of a nonparasitic hepatic cyst with biliary communication is rare. We report the case of a patient with a hepatic cyst with biliary communication that spontaneously ruptured and was successfully treated by laparoscopic deroofing and closure of the communication. A 61-year-old woman presented at our hospital with a chief complaint of right upper(More)
A 77-year-old man underwent surgery for sigmoid colon cancer. He was diagnosed with Stage IIIa colon cancer; there- fore, we initiated oral administration of adjuvant chemotherapy comprising uracil/tegafur(UFT)plus Leucovorin(LV). However, chemotherapy was stopped after 21 days because of fatigue and diarrhea. He recovered after 3 weeks, and we administered(More)
BACKGROUND Carcinomas occurring at colostomy sites are rare, and most of these are metachronous colorectal cancers. The median time between colostomy and development of a carcinoma at a colostomy site is 22 years, which exceeds the length of the recommended follow-up period. We report a rare case of a carcinoma of the transverse colon occurring at a(More)
