Endoscopic balloon dilatation (EBD) and surgical intervention are two most common and effective treatments for gastric outlet obstruction. Correction of gastric outlet obstruction without the need for surgery is an issue that has been tried to be resolved in these decades; this management has developed with EBD, advanced treatments like local steroid injection, electrocauterization, and stent have been added recently. The most common causes of pediatric gastric outlet obstruction are idiopathic hypertrophic pyloric stenosis, peptic ulcer disease followed by the ingestion of caustic substances, stenosis secondary to surgical anastomosis; antral web, duplication cyst, ectopic pancreas, and other rare conditions...

BACKGROUND AND AIMS: Benign gastrointestinal strictures occur typically in the esophagus and pyloric channel, but can occur anywhere in the GI tract and at anastomotic sites. Such strictures can be treated with dilation, incisional therapy, steroid injection and stents. Our aim was to describe the use of a lumen-apposing metal stent (LAMS) to treat short, benign gastrointestinal strictures. PATIENTS AND METHODS: Retrospective review of consecutive patients who underwent LAMS placement for various benign strictures at 2 tertiary care centers from August 2014 to November 2015...

Pylorus-preserving gastrectomy (PPG) is a function-preserving surgery for the treatment of early gastric cancer (EGC), aiming to decrease the complication rate and improve postoperative quality of life. According to the Japanese gastric cancer treatment guidelines, PPG can be performed for cT1N0M0 gastric cancer located in the middle-third of the stomach, at least 4.0 cm away from the pylorus. Although the length of the antral cuff gradually increased, from 1.5 cm during the initial use of the procedure to 3...

BACKGROUND: Several studies report on the outcomes of self-expandable metallic stents (SEMS) deployment for malignant gastric outlet obstruction (GOO). However, data was based on the analysis of single center studies. Additionally, only a small number of patients was included, despite a prospective multicenter study in most reports. AIMS: The evaluation of clinical outcomes after the deployment of SEMS in patients with malignant GOO in addition to a comparison of the clinical outcomes of two metallic stents with different designs...

Carter Lebaras, Lee L Swanstrom
A growing body of literature supports the use of laparoscopic pyloroplasty as a minimally invasive treatment of refractory gastroparesis that has failed conservative measures and for benign gastric outlet obstruction. Endoscopic pyloric dilation, stent placement, and Botox have been described for similar indications, but often with transient or mixed results. Per-oral pyloromyotomy has recently been proposed as an endoscopic alternative to surgical pyloroplasty or pylormyotomy because it is less invasive by its nature and potentially more durable than current endoscopic treatments...

This review of the pathophysiologic basis for gastroparesis and recent advances in the treatment of patients with gastroparesis shows that there are several novel approaches to advance treatment of gastroparesis including diet, novel prokinetics, interventions on the pylorus, and novel forms of gastric electrical stimulation. The field of gastroparesis is likely to advance with further studies, with help from a guidance document from the Food and Drug Administration on gastroparesis, and with recent approval of the stable isotope gastric emptying test to ensure eligibility of participants in multicenter trials...

A 68-year-old man presenting with anorexia was admitted to our hospital; he was diagnosed with pyloric stenosis arising from a type 3 tumor in the antrum of the stomach. Pathological examination revealed a poorly differentiated adenocarcinoma; immunohistochemical staining tested positive for alpha fetoprotein(AFP), and negative for human epidermal growth factor receptor 2(HER2). Abdominal computed tomography (CT) showed a portal vein thrombus and enlarged lymph nodes. Since the clinical finding was Stage IV(T4aN3M1), curative surgery was ruled out...

Gastroparesis is a syndrome characterized by delayed gastric emptying with associated symptoms. Gastric emptying is a complex process and pyloric dysfunction may play a key role in select subsets of patients with gastroparesis. Diagnostic tests to measure pyloric physiology are now available and have the potential to be more widely used in clinical practice. Targeted therapies including botulinum toxin, transpyloric stent placement, surgical pyloroplasty and endoscopic pyloromyotomy have been developed. Data are emerging regarding efficacy and durability, but these therapies may play a prominent role in select patients with gastroparesis and pyloric dysfunction...

We observed a case of unresectable Stage IV human epidermal growth factor receptor 2(HER2)-positive advanced gastric cancer treated by using trastuzumab combined with chemotherapy. A 55-year-old man was admitted to our hospital because of dysphagia for 4 months. He was diagnosed with advanced gastric cancer with pyloric stenosis, multiple lung metastases, multiple liver metastases, peritoneal dissemination, and rectal muscle invasion. First, we initiated weekly chemotherapy with paclitaxel. Because the biopsy tissue was HER2-positive, we added trastuzumab to the weekly paclitaxel regimen...

BACKGROUND: Controversy still exists about the need for pyloric drainage procedures after esophagectomy with gastric conduit reconstruction. Although pyloric drainage may prevent postoperative delayed gastric emptying (DGE), it may also promote dumping syndrome and bile reflux. The aims of this study were to audit the incidence and management of DGE in patients without routine pyloric drainage after esophagectomy in a university medical center. PATIENTS AND METHODS: From July 2006 to June 2012, data from 356 consecutive patients who underwent esophagectomy with a gastric conduit without pyloric drainage for esophageal or gastric cardia carcinoma were reviewed...

Herein, we report the case of 57-year-old woman who visited our hospital for abdominal distention, difficulty in walking, and edema of the legs in January 2012. She underwent gastroendoscopy, resulting in a diagnosis of advanced gastric cancer of the pyloric antrum. A diagnosis of unresectable advanced gastric cancer was made because computed tomography (CT) showed the presence of ascites (suspected to indicate peritoneal dissemination), para-aortic lymph node metastases, and brain metastases. Stenting was performed for pyloric stenosis and cell-free and concentrated ascites reinfusion therapy (CART) was administered to facilitate oral intake...

We examined 11 gastric cancer patients undergoing gastroduodenal stent placement for the treatment of gastric outlet obstruction at our hospital, and assessed the significance and problems associated with stenting. None of the patients exhibited any complications associated with stenting, and the median post-stenting fasting period was 3 days(range, 1-7 days). Oral intake improved significantly in all the patients; in patients with nasogastric tubes, the tubes were removed after stenting. However, in patients with peritoneal dissemination, oral intake alone was not sufficient, and additional parenteral nutrition was required...

BACKGROUND/AIMS: The use of self-expandable metallic stents (SEMS) is an established palliative treatment for malignant stenosis in the gastrointestinal tract; therefore, its application to benign stenosis is expected to be beneficial because of the more gradual and sustained dilatation in the stenotic portion. We aimed in this prospective observational study to evaluate the efficacy and safety of temporary SEMS placement in benign pyloric stenosis. METHODS: Twenty-two patients with benign stenosis of the prepylorus, pylorus, and duodenal bulb were enrolled and underwent SEMS placement...
