Between March and April 2009, three consecutive patients underwent single-incision laparoscopic gastric wedge resection for a submucosal tumor located in the anterior wall or greater curvature of the stomach. First, we placed two or three trocars through the same infra-umbilical skin incision. Then, we either elevated the tumor with a mini-loop retractor or(More)
INTRODUCTION Single-port laparoscopic adrenalectomy is one of the most interesting surgical advances. Here, we evaluate the safety and feasibility of single-port laparoscopic adrenalectomy as treatment for a right-sided aldosterone-producing adenoma. CASE PRESENTATION A 39-year-old Japanese woman presented with hypertension and hypokalemia. Abdominal(More)
Non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are increasingly common cause of chronic liver disease worldwide. The diagnosis of NASH is challenging as most affected patients are symptom-free and the role of routine screening is not clearly established. Most patients with severe obesity who undergo bariatric surgery have(More)
Laparoscopic major hepatectomy (LMH) is an innovative procedure that is still in the exploration phase. Although new surgical techniques have learning curves, safety should be maintained from the onset. This retrospective study was conducted to evaluate the safe introduction of LMH. We retrospectively reviewed data from 245 consecutive patients who(More)
Single-port laparoscopic cholecystectomy (SPLC) is an emerging technique and gaining increased attention by its superiority in cosmesis. A 1.5-cm vertical transumbilical incision is used for the single port, followed by the glove method. Indications for SPLC are the same as those for standard 4-port laparoscopic cholecystectomy, including patients with(More)
Between March 2003 and March 2007, three patients with benign pancreatic tumors underwent a planned laparoscopic spleen-preserving distal pancreatectomy with conservation of the splenic artery and vein. Four trocars were placed, and an endoscopic linear stapler was used to transect of the pancreas. The perioperative data and surgical outcomes were examined.(More)
BACKGROUND AND AIM The aim of the present study was to evaluate gastric motor function by magnetic resonance imaging (MRI) and investigate whether this examination is a useful tool for therapeutic efficacy or postoperative gastric motor function. METHODS Twenty-five healthy volunteers and 10 gastric cancer patients with pylorus-preserving gastrectomy(More)
We herein report a case of single-port laparoscopic and endoscopic cooperative surgery (LECS) for a gastric gastrointestinal stromal tumor (GIST). A 75-year-old female with an endoluminal GIST located near the esophagogastric junction underwent LECS. Both the mucosal and submucosal layers around the tumor were circumferentially dissected using endoscopic(More)
Totally laparoscopic liver resection (TLLR) is still a challenging procedure, although experienced liver surgeons have performed this operation successfully. Between May 1997 and October 2009, 97 patients at Iwate Medical University Hospital underwent TLLR, which included 79 partial resections, 15 left lateral sectionectomies, two S5 subsegmentectomies, and(More)
Our objective was to establish the efficiency of single-incision laparoscopic Heller myotomy and Dor fundoplication (SILHD) as treatment for esophageal achalasia. A 58-year-old man underwent SILHD for achalasia. The left triangular ligament was retracted using a suture thread and fixed to the body surface, providing a good operative field at the cardia. We(More)
