Purpose. Patients who have undergone low anterior resection (LAR) of the rectum occasionally complain of symptoms related to impaired neorectal evacuation. Using scintigraphy, we assessed neorectal evacuation in 22 patients who underwent LAR and straight anastomosis, and correlated the results with clinical defecatory function, clinical factors, and(More)
We review the techniques and outcomes of the intragastric resection for gastric submucosal tumors (GSTs) using laparoscope and oral endoscope. In the literature, the mean operation time, intraoperative blood loss, pathological size of the tumor and postoperative hospital stay were 134 min, minimal, 31 mm and 6.4 d, respectively. There were no particular(More)
BACKGROUND Recent advances in colonoscopy have resulted in an increasing number of endoscopic resections of colorectal neoplasms. However, endoscopic resection of submucosal invasive cancer remains a controversial issue. METHODS The subjects for this study were the surgically treated patients with submucosal invasive colorectal cancer. These patients were(More)

Background and aims. Colonic J-pouch anastomosis after low anterior resection of the rectum has been reported to be associated with an increased risk of evacuation difficulty. Using scintigraphy we compared neorectal emptying after stapled low anterior resection between colonic J-pouch anastomosis and straight anastomosis. Patients and methods. We studied(More)
Appendico-vesical fistula is a rare condition. In total, 109 cases, most secondary to appendicitis, have been reported in the English-language litera-ture. We report the first case, to our knowledge, of appendico-ileo-vesical fistula secondary to appendiceal diverticulitis. An enterovesical fistula was diagnosed by urine culture, cystoscopy, and computed(More)
INTRODUCTION Paraesophageal hiatal hernia is often associated with a number of complications such as intestinal obstruction, gastric volvulus and acute pancreatitis, each of which can result in critical conditions requiring surgery. Herein, we report our surgical procedure for paraesophageal hiatal hernia. METHODS Since 2003, we have surgically treated(More)
Liver biopsy (LB) is an important procedure in the diagnosis and treatment of liver diseases. However, procedures for performing LB vary amongst institutions, and no universal guide‐ lines exist. LB is performed for two main reasons: diagnosis of a liver condition itself, and as an adjunct to an existing surgical procedure. Recently, it has become possible(More)
INTRODUCTION Cage migration into the retroperitoneal space during posterior lumbar interbody fusion rarely occurs. Here, we report a patient who underwent laparoscopic surgery to remove a migrated cage from the retroperitoneal space. CASE PRESENTATION A 76-year-old woman had a cage that had migrated into the retroperitoneal space during posterior lumbar(More)
