Balloon dilatation followed by triamcinolone acetonide injection for colostomy stenosis: A case report.

Introduction: Stenosis is a serious complication associated with stomas. The initial treatment for stoma stenosis is mainly the finger-bougie technique or balloon dilatation, and recurrence requires stomal reconstruction. However, the use of local triamcinolone injections for treating stoma stenosis has not been reported.

A technique for esophagojejunostomy following robot-assisted gastrectomy: a liner stapler and barbed suture device-based technique: a case series.

Unlabelled: Intracorporeal esophagojejunostomy after total or proximal robot-assisted gastrectomy is technically more demanding than gastroduodenostomy and gastrojejunostomy for distal gastrectomy, as well as laparoscopic surgery. We have established a safe and simple esophagojejunostomy procedure using a liner stapler attached to the Da Vinci Surgical System and a barbed suture device.

Patients And Methods: For esophagojejunostomy after total gastrectomy or proximal gastrectomy with double-tract reconstruction, we choose the "overlap method," in which entry holes were made at the left of the esophageal stump and at 5 cm of the anal side in antimesentric area of the jejunum, followed by anastomosis on the left of the esophagus using SureForm (blue 45 mm) and hand-sewing closure of the common entry hole with V-Loc.

Usefulness of percutaneous transesophageal gastrotubing for gastric outlet obstruction secondary to duodenal ulcer, a case report.

Severe duodenal ulcer stenosis requires continuous decompression, which makes oral ingestion difficult, yet poor nutritional status before surgery increases the risk postoperative complications. Double percutaneous transesophageal gastrotubing (dPTEG) is a new treatment that provides both decompression and enteral nutrition. We report a case of duodenal ulcer scar stenosis in which dPTEG was used for preoperative management.

Double percutaneous transesophageal gastrotubing precluded high risk surgery for intestinal malignant lymphoma.

Primary gastrointestinal lymphoma is relatively rare and typically treated by chemotherapy. In some cases, surgery for obstruction in the proximal small intestine is challenging and has a high risk for anastomotic leakage. An 80-year-old woman presented to our hospital with vomiting and abdominal distension.

Indocyanine green fluorescence-guided laparoscopic colorectal cancer surgery with prophylactic retrograde transileal conduit ureteral catheter placement after previous total cystectomy: a case report.

Background: Iatrogenic ureteral injury (UI) is a potentially serious complication of colorectal cancer surgery. Performing perioperative placement of ureteral stents or intraoperative fluorescence navigation surgery for the ureter using indocyanine green (ICG) has been employed as a method of preventing UI. However, transileal conduit stent placement has been considered challenging because it is difficult to identify the ureteral orifice due to the anatomical changes caused by a previous surgery.

New Technique for Magnetic Compression Anastomosis Without Incision for Gastrointestinal Obstruction.

Background: Magnetic compression anastomosis (MCA) is a novel technique of anastomosis similar to that with surgery, but in a minimally invasive manner. Few reports are available on the utility and feasibility of MCA for gastrointestinal anastomosis without requiring general anesthesia in humans, owing to the difficulty of delivering magnets. We evaluated the safety, efficacy, and feasibility of MCA in gastrointestinal obstruction without requiring general anesthesia.

Magnetic compression anastomosis is effective in treating stenosis after esophageal cancer surgery: a case report.

Background: Esophagostomy is important in the treatment of esophageal cancer. However, esophagectomy has a higher risk of postoperative complications. Treatment for complications is often difficult, and in some cases, oral intake is no longer possible.

One-stage fluoroscopy-guided laparoscopic transcystic papillary balloon dilation and laparoscopic cholecystectomy in patients with cholecystocholedocholithiasis who previously had undergone gastrectomy for gastric cancer.

Background: Patients with a history of gastrectomy have a higher incidence of cholecystocholedocholithiasis (CCL) and related morbidities than the general population. However, the management of common bile duct (CBD) stones with endoscopic retrograde cholangiopancreatography is challenging in patients after Roux-en-Y or Billroth II reconstruction because of the altered gastrointestinal anatomy. The aim of the current study was to evaluate the safety and efficacy of one-stage laparoscopic transcystic papillary balloon dilation and laparoscopic cholecystectomy (LTPBD+LC) in patients with previous gastrectomy for gastric cancer.

One-stage fluoroscopic-guided laparoscopic transcystic papillary balloon dilation and laparoscopic cholecystectomy for the treatment of choledocholithiasis after Roux-en-Y reconstruction.

Patients with a history of gastrectomy have a higher incidence of cholecystocholedocholithiasis and morbidities. In particular, the management of choledocholithiasis with endoscopic retrograde cholangiopancreatography (ERCP) has been challenging in patients after Roux-en-Y or Billroth II reconstruction due to the altered gastrointestinal anatomy. A 92-year-old man presented with high fever.

Magnetic compression anastomosis for non-anastomotic stenosis of the proximal jejunum after total gastrectomy with Roux-en-Y reconstruction: a case report.

Background: Postoperative non-anastomotic stenosis of the proximal jejunum after total gastrectomy with Roux-en-Y reconstruction is a rare complication. If endoscopic balloon dilation proves ineffective, patients need re-operation under general anesthesia and experience a high rate of postoperative complications. Magnetic compression anastomosis is a nonsurgical procedure that can create an anastomosis similar to that obtained through surgery.

Fluoroscopic balloon dilation for early jejunojejunostomy obstruction after gastrectomy with roux-en-Y reconstruction: a case series of three patients.

Background: Small bowel obstruction after gastrectomy with Roux-en-Y reconstruction (R-Y reconstruction) is not a rare complication. However, patients who need re-operation for this complication have a high rate of postoperative complications. We report a case series of three patients who underwent fluoroscopic balloon dilation (FBD) for early jejunojejunostomy obstruction (JJO) after gastrectomy with Roux-en-Y reconstruction (R-Y reconstruction).

Magnetic compression anastomosis with atypical anastomosis for anastomotic stenosis of the sigmoid colon: a case report.

Background: Magnetic compression anastomosis (MCA) is mainly applied in the gastrointestinal and biliary tracts through a nonsurgical procedure that can create an anastomosis similar to that obtained through surgery. Magnets usually adsorb in the end-to-end direction (end-to-end anastomosis), exert a strong magnetic force and create an anastomosis according to the size of the magnets. Regular endoscopic dilation is required to prevent restenosis when the anastomotic size is small.

Double Percutaneous Transesophageal Gastrotubing for Gastric Cancer: A Pilot Study.

Background: The management of gastric cancer causing gastric outlet obstruction and dilatation must include decompression of the stomach and intravenous nutrition. Percutaneous transesophageal gastrotubing (PTEG) is an effective technique for either gastric decompression or enteral nutrition. Here, we investigated the efficacy and safety of double PTEG (dPTEG), that is, using PTEG for both purposes simultaneously, in patients with gastric cancer.

Magnetic compression anastomosis for the complete dehiscence of hepaticojejunostomy in a patient after living-donor liver transplantation.

Background: Magnetic compression anastomosis (MCA) is a minimally invasive method of anastomosis that does not involve a surgical procedure in patients with stricture, obstruction, or dehiscence of anastomosis after surgery. We experienced a case of complete dehiscence of bilioenteric anastomosis that was successfully treated by MCA.

Case Presentation: A 55-year-old woman received ABO-incompatible right-lobe living-donor liver transplantation with hepaticojejunostomy for the right anterior duct (RAD) and right posterior duct (RPD).

Serum matrix metalloproteinase-1 level represents disease activity as opposed to fibrosis in patients with histologically proven nonalcoholic steatohepatitis.

Background/aims: Nonalcoholic steatohepatitis (NASH) is prevalent in both economically developed and developing countries. Twenty percent of NASH progresses to cirrhosis with/without hepatocellular carcinoma, and there is an urgent need to find biomarkers for early diagnosis and monitoring progression of the disease. Using immunohistochemical and immunoelectron microscopic examination we previously reported that expression of matrix metalloproteinase-1 (MMP-1) increased in monocytes, Kupffer cells and hepatic stellate cells in early stage NASH.

Magnetic compression anastomosis for postoperative biliary atresia.

We report a case of successful magnetic compression anastomosis (MCA) for obstructed cyst-jejunostomy in a young woman who had undergone surgery for type 1 biliary atresia (BA) on day 78 of life. A 16-year-old girl was admitted with obstructive jaundice. Jaundice resolved with percutaneous trans-hepatic cholangiodrainage (PTCD) but contrast medium injected from the PTCD tube did not flow through the anastomosis.

Proposed cut-off value of the intrahepatic lipid content for metabolically normal persons assessed by proton magnetic resonance spectroscopy in a Japanese population.

Aims: To determine the threshold intrahepatic lipid (IHL) content separating metabolically normal from abnormal in a Japanese population based on proton magnetic resonance spectroscopy ((1)H-MRS).

Methods: A total of 305 Japanese subjects aged 20-69years were investigated. The subjects underwent general examination, blood tests, and (1)H-MRS of the liver after an overnight fast.

Endoscopic computerized tomography guided percutaneous trans-gastric drainage: A case report on this hybrid approach.

Percutaneous drainage, percutaneous transgastric drainage, and endoscopic ultrasound (EUS)-guided transgastric drainage are primarily utilized for drainage of fluid collections dorsal to the stomach. Percutaneous transgastric drainage is performed with computed tomography (CT) guidance, but it requires inflation of a balloon in the stomach, and gastric peristalsis makes it difficult to ensure a reliable puncture route via the stomach. Using endoscopy-assisted CT-guidance, we were able to safely and effectively perform percutaneous transgastric drainage.

Proposed cut-off values of the waist circumference for metabolic syndrome based on visceral fat volume in a Japanese population.

Aim/introduction: Waist circumference (WC) is the most important parameter for diagnosis of metabolic syndrome. The present study was carried out to obtain optimal WC cut-off values for diagnosis of metabolic syndrome in a Japanese population based on the measurement of total intra-abdominal visceral fat volume (VFV), which could be expected to reflect visceral obesity more precisely than visceral fat area.

Materials And Methods: A total of 405 Japanese persons undergoing health screening were investigated.

Fibrogenesis and Carcinogenesis in Nonalcoholic Steatohepatitis (NASH): Involvement of Matrix Metalloproteinases (MMPs) and Tissue Inhibitors of Metalloproteinase (TIMPs).

Nonalcoholic steatohepatitis (NASH) is emerging worldwide because life-styles have changed to include much over-eating and less physical activity. The clinical and pathophysiological features of NASH are very different from those of HBV- and HCV-chronic liver diseases. The prognosis of NASH is worse among those with nonalcoholic fatty liver diseases (NAFLD), and some NASH patients show HCC with or without cirrhosis.

Magnetic compression anastomosis for biliary obstruction: review and experience at Tokyo Medical University Hospital.

Background: Magnetic compression anastomosis (MCA) is a revolutionary, minimally invasive method of performing choledochoenterostomy or choledochocholedochostomy without using surgical techniques in patients with biliary stricture or obstruction. Herein, we describe a case series of MCA for severe biliary stricture or obstruction, which could not be treated with conventional therapies.

Patients And Methods: Two patients with biliary obstruction were treated using MCA for choledochocholedochostomy and choledochoenterostomy at Tokyo Medical University Hospital and Tokyo Medical University Hachioji Medical Center.
