A 30-year-old Japanese woman presented at our hospital with a pancreatic tumor. Contrast-enhanced CT revealed a tumor with a 12-cm diameter in the pancreatic body and tail. In the preoperative setting, endoscopic ultrasound-guided fine-needle aspiration permitted a histopathological diagnosis of solid pseudopapillary neoplasm. Twhe patient underwent laparoscopic distal pancreatectomy with splenectomy. Our procedure involved three steps. Firstly, the splenic artery was occluded to block inflow of blood to the tumor...

Synchronous multiple malignant colorectal lesions are rare, and there have been very few studies about one-stage laparoscopic operations in these cases. Here, we evaluated the short-term outcomes of laparoscopy-assisted colectomy (LAC) for synchronous double colorectal cancers. Seven patients underwent one-stage LAC that required two resections and anastomoses in our hospital from 2010 to 2014. We retrospectively examined each patient's background and subsequent surgical outcomes. The median age of patients was 78 years, and the median BMI was 19...

INTRODUCTION: Laparoendoscopic single-site surgery is a recently innovated urologic surgical procedure. Transumbilical laparoendoscopic single-site adrenalectomy (LESS-A) is technically safe and feasible in patients with benign adrenal tumors. To improve patient counseling and informed consent, we evaluated patient-reported postoperative pain, body image, and cosmetic satisfaction after transumbilical LESS-A. METHODS: We reviewed 24 patients who underwent transumbilical LESS-A and assessed their operative and esthetic outcomes and incisional pain...

INTRODUCTION: Laparoscopy-assisted distal gastrectomy is one of the major treatments for early stage gastric cancer, particularly in the East Asia. In this method, extracorporeal anastomosis is performed via a small laparotomy wound, but excessive tissue traction may be encountered during the anastomotic procedure. Therefore, we developed an original procedure for extracorporeal Billroth-I reconstruction: end-to-end stapling gastroduodenostomy with complete double stapling technique. This procedure aims to reduce the problems related to maneuvers through a small laparotomy...

For neuroendocrine tumor G1, local resection is one of the primary treatment options. Endoscopic submucosal dissection has been proven to ensure complete resection with sufficient margins. However, duodenal endoscopic submucosal dissection has a high risk of duodenal perforation because of the thin duodenal wall and poor endoscopic maneuverability. During laparoscopic dissection, suturing can resolve perforation. Therefore, laparoscopic-endoscopic cooperative surgery (LECS) can ensure complete resection with a minimal margin to prevent stenosis, and suturing can resolve perforation...

INTRODUCTION: Accidental gallbladder perforation frequently occurs during laparoscopic cholecystectomy and may increase the risk of infection. However, the necessity of antimicrobial prophylaxis for these patients is unclear. The aim of this study was to examine the clinical outcomes and necessity of antimicrobial prophylaxis after laparoscopic cholecystectomy with gallbladder perforation. METHODS: One hundred patients who underwent laparoscopic cholecystectomy were divided into two groups: patients with gallbladder perforation (Group A, n = 37) and patients without perforation (Group B, n = 63)...

INTRODUCTION: CT angiography has gained widespread acceptance for preoperative evaluation of blood supply in patients with colorectal cancer. However, there have been few reports that pertain to the splenic flexure, for which surgery is technically difficult. We used preoperative CT angiography and CT colonography to evaluate blood supply to the splenic flexure. METHODS: We defined the splenic flexure as the junction of the distal third of the transverse colon and the proximal third of the descending colon...

BACKGROUND: Intraoperative hypothermia is linked to postoperative adverse events. The use of warmed, humidified CO2 to establish pneumoperitoneum during laparoscopy has been associated with reduced incidence of intraoperative hypothermia. However, the small number and variable quality of published studies have caused uncertainty about the potential benefit of this therapy. This meta-analysis was conducted to specifically evaluate the effects of warmed, humidified CO2 during laparoscopy...

INTRODUCTION: Laparoscopic liver resection (LLR) has been widely performed throughout the world. Although prospective registry studies to clarify the safety of LLR have been feasible, no prior multicenter prospective study has addressed this issue. We have conducted a multicenter prospective cohort study to reveal the current status of LLR in Japan. METHODS: From April 2015 to March 2016, candidates for LLR were preoperatively enrolled at 12 institutions. The primary end-point was surgical safety, which was evaluated based on surgical factors and on short-term and midterm outcomes...

Laparoscopic-assisted abdominoperineal resection and en-bloc prostatectomy using the trans-sacral approach for locally invasive rectal cancer that invades only the prostate is useful in order to avoid total pelvic exenteration. The patient was a 63-year-old man with cT4b (prostate) N1M0, stage IIIC rectal cancer. Curative resection was performed. Histopathological findings did not indicate definitive invasion into the prostate gland. The patient was discharged from the hospital on postoperative day 32 with an anastomotic leak and a ureteral catheter...

INTRODUCTION: Although endoscopic procedures for lumbar disc diseases have improved greatly, treating migrated disc herniation is still a challenging task. Because of anatomic limitations, a rigid endoscope cannot effectively reach the herniated nucleus pulposus (HNP) in the hidden zone. The purpose of this study was to describe the transpedicle approach for HNP in the hidden zone using the percutaneous endoscopic lumbar discectomy system and to demonstrate the clinical results. Materials and Surgical Technique: Under fluoroscopy, the percutaneous endoscopic lumbar discectomy cannula is placed on the superior articular process, and a trephine with a diameter of 7...

INTRODUCTION: Laparoscopic hepatectomy is difficult because surgeons must perform the transection using many (four and more) energy devices and without direct manual maneuvers. Here we introduce hepatic transection by the classical method with a few (two or three) energy devices. MATERIALS AND SURGICAL TECHNIQUE: We performed laparoscopic hepatectomy for 40 patients with hepatic tumor and liver dysfunction. For parenchymal transection, we used bipolar radiofrequency coagulation forceps connected to a voltage-controlled electrosurgical generator and ultrasonic dissector...

INTRODUCTION: We employed a safe approach during laparoscopic splenectomy by first mobilizing the pancreatic tail and then dissecting the splenic vessels at the splenic hilum before mobilizing the spleen. MATERIALS AND SURGICAL TECHNIQUE: Patients were placed in the lithotomy position, and only the upper body was twisted to the right side. Five trocars were placed. After the bursa omentalis was opened, an avascular layer was identified behind the pancreas. This avascular layer was bluntly dissected, and the pancreatic tail was isolated from the retroperitoneum...

INTRODUCTION: The intra-operative detection of hepatocellular carcinoma (HCC) by ultrasonography is indispensable for laparoscopic partial hepatectomy. However, it is occasionally difficult to localize an HCC on an ultrasound in chronic liver disease. Two cases of partial hepatectomy using hookwire marking under CT guidance are presented. MATERIALS AND SURGICAL TECHNIQUE: The location of the HCC was identified by CT scan, and the puncture site was determined. A hookwire system, made of a stainless steel hook, was used to localize the HCC...

INTRODUCTION: To minimize the resection of stomach tissue, especially for lesions close to the esophagogastric junction or pyloric ring, we developed laparoscopic wedge resection with the serosal and muscular layers incision technique (SAMIT) for gastric gastrointestinal stromal tumors. MATERIALS AND SURGICAL TECHNIQUE: SAMIT involves resection of the mucosal and submucosal layers and then an incision in serosal and muscular layers around the tumor. SAMIT is simple and does not require special devices...
