Purpose: Identification of the infrapyloric artery (IPA) type is a key component of pylorus-preserving gastrectomy. As the indocyanine green (ICG) fluorescence technique is known to help visualize blood vessels and flow during reconstruction, we speculated that this emerging technique would be helpful in identifying the IPA type. Materials and Methods: From August 2015 to February 2016, 20 patients who underwent robotic or laparoscopic gastrectomy were prospectively enrolled. After intravenous injection of approximately 3 mL of ICG (2.5 mg/mL), a near-infrared fluorescence apparatus was applied. The identified shape of the IPA was confirmed by examining the actual anatomy following infrapyloric dissection. Results: The mean interval time between ICG injection and visualization of the artery was 22.2 seconds (range, 14-30 seconds), and the mean duration of the arterial phase was 16.1 seconds (range, 9-30 seconds). The overall positive predictive value (PPV) of ICG fluorescence in identifying the IPA type was 80% (16/20). The IPA type was incorrectly predicted in four patients, all of whom were obese with a body mass index (BMI) of more than $25kg/m^2$. Conclusions: Our preliminary results indicate that intraoperative vascular imaging using the ICG fluorescence technique may be helpful for robotic or laparoscopic pylorus-preserving gastrectomy.

Purpose: To report our experience of endoscopic botulinum toxin injection in patients who experienced severe delayed gastric emptying after pylorus-preserving gastrectomy (PPG). Materials and Methods: We reviewed the medical records of 6 patients who received the botulinum toxin injection. They presented with severe delayed gastric emptying in the early postoperative period. Endoscopic botulinum toxin was administered as 4 injections of 25-50 IU into each of the 4 quadrants of the prepyloric area. Results: All botulinum toxin injections were successful without any complications, enabling 5 patients to tolerate soft solid diets and one to tolerate a soft fluid diet within 10 days. The endoscopic criteria of 4 patients improved. Symptom recurrence caused 2 patients to undergo repeat injections that were successful. The median follow-up period was 27 months, and all patients could ingest normal regular diets at the last follow-up. Conclusions: Endoscopic botulinum toxin injection is a feasible treatment option for early delayed gastric emptying after PPG.

Objectives This study aimed to observe the effect of Taeumjowi-tang on the cisplatin-induced gastrointestinal dysfunctions in rats. Methods Four groups, each of 8 rats per group, were used in this study. Saline and distilled water treated control rats were intact vehicle control group. Delayed gastrointestinal motility was induced by intraperitoneal treatment of cisplatin 2mg/kg, once a week for 5 weeks(Cisplatin control group). Taeumjowi-tang aqueous extracts(TJ) were orally administered in a volume of 5ml/kg, once a day for 14 days from 4th cisplatin treatment(TJ group). Ondansetron 1mg/kg was subcutaneously treated, in a volume of 1ml/kg, as same as TJ(ondansetron group). We measured the body weights, intestinal charcoal transit ratio, fecal parameters, fundus MDA(malondialdehyde), GSH(glutathione) contents and SOD(superoxide dismutase), CAT(catalase) activities, TPH(tryptophanhydroxylase) and MAO(monoamine oxidase) activities, pyloric gastrin and serotonin contents with their immunoreactive cells, colonic serotonin-immunoreactive cells, the histopathology of pylorus, fundus mucosa and colon. Results 1) The body weight gains, the small intestinal charcoal transfer rates, the fecal parameters(numbers, weights and water contents) were increased in TJ, ondansetron group. 2) The inhibit of fundus antioxidant defense systems by cisplatin were decreased in TJ, ondansetron group. 3) The pyloric TPH activities were increased and the pyloric MAO activities were decreased in TJ group. 4) The pyloric gastric contents and the gastrin-immunoreactive cells were increased and the pyloric serotonin contents and the pyloric and colonic serotonin-immunoreactive cells were decreased in TJ group. 5) The pylorus atrophic changes and the gastric surface erosive damage regions by cisplatin were favorably inhibited by treatment of TJ group. Conclusions The results obtained in this study suggest that TJ favorably retarded the cisplatin related GI(gastrointestinal) dysfunctions and constipation through modulations of GI enterochromaffin cells, serotonin and gastrin-producing cells and antioxidative systems.

Rapunzel syndrome refers to a very rare condition in which swallowed hair forms a gastric trichobezoar that has a long tail extending into the small bowel. We describe a case of Rapunzel syndrome in an 8-year-old girl who presented with abdominal mass, epigastric pain and vomiting. Abdominal computed tomography scan showed a markedly dilated stomach filled with coarse heterogeneous materials. Upper gastrointestinal endoscopy revealed a huge hairy ball with a tail extending through the pylorus. We performed a surgical laparotomy and successfully removed a huge trichobezoar with a long tail extending into the middle portion of jejunum. Psychiatric consultation with review showed her past history of trichotillomania and trichophagia 4 years ago. But her parents denied further psychiatric therapy and she was lost to the follow-up. Rapunzel syndrome should be included in the differential diagnosis in children with chronic abdominal pain and trichophagia.

A 4-month-old, intact male, Tosa with a history of a regurgitation, vomiting, and weight loss for three weeks was presented to Animal Medical Center, Chonbuk National University. In Serial plain radiographs, a severely distended stomach was seen and ultrasonogram revealed a nonfunctional pylorus with normal layer comparable with an obstruction of pyloric region by pyloric achalasia. An esophagram and endoscopy revealed normal peristalsis with failure of the lower esophageal sphincter to open, supporting the diagnosis of esophageal achalasia. Megaesophagus was observed on reradiograph and esophagram 11 days later. The clinical signs and esophageal dilation were resolved without resorting to any treatment.

Surgical treatment was performed in 507 heads out of 1078 dairly cows which were diagnosed as abomasal displacement. Out of 507 heads. bar suture was performed in 280 heads. Twelve heads out of 280 heads(4.9%) recurred. Incorrective suture of the reticulum or pylorus instead of abomasum occurred in 3 cows. The cows in which abdominal wall was sutured but the suture was not inserted into the abomasum were 4 heads. The cows in which bar was broken are 4 heads. A cow suffered peritonitis after bar suture. Bar suture technique is thought to be a good method as a first choice for the correction of abomasal displacement.

In a preliminary screening of plant extracts for the antigastritic and antiulcer actions in rats, the extracts of head of Panax ginseng Radix showed positive activity in HCl ethanol-induced gastric lesion. Among the systematic fractions of hexane, chloroform, butanol and water, the most potent butanol fraction reduced significantly HCl ethanol-induced gastric lesion at the oral dose of 500 mg/kg. In pylorus ligated rats, hexane and butanol fraction showed decreases in the volume of gastric secretion and acid output, of which effects were stronger in butanol fraction. Further assays with butanol fraction disclosed that it significantly suppressed the aspirin-induced and Shay ulcer. The butanol fraction at the intraduodenal dose of 500 mg/kg showed significant stimulation of mucus secretion.

A 2-year-old neutered male Bengal cat presented with a 6-month history of weight loss and chronic vomiting. An abdominal ultrasound revealed increased thickness of the pylorus and ascending duodenum with concurrent enlargement of the mesenteric lymph nodes. Histologically, branching and anastomosing trabecular pattern of dense collagen was the characteristic feature, and large populations of spindle cells were also observed. These large spindle-shaped cells were positive for smooth muscle actin and vimentin on immunohistochemical examination. Based on these findings, the cat was diagnosed with feline gastrointestinal eosinophilic slcerosing fibroplasia (FGESF), and immunosuppressive therapy was initiated immediately. Unfortunately, the cat's condition deteriorated despite treatment; the cat died 56 days after initiation of therapy. This is the first report of FGESF in South Korea.

Alnus japonica cortex has been used as antidiarrhea, antihemorrhage and the remedy of indigestion. This study was performed to investigate the effectiveness of the methanol extracts of the Alnus japonica cortex on the gastric lesion and ulcer. The methanol extract was fractionated with hexane, chloroform and butanol, followed by bioassay on antigastritic and antiulcer activity. The methanol extract showed low acute toxicity with minimum lethal dose of more than 5000 mg/kg, p.o. in mice. The chloroform and the butanol fraction reduced gastric lesion in HCI. ethanol induced gastritic model. On gastric secretion in pylorus ligated rat, the hexane and chloroform fraction decreased the volume and acidity. The butanol fraction had significant inhibitory effects on aspirin and Shay's ulcer. The butanol fraction showed a tendency to inhibit the decrease of mucin secretion due to ingestion of absolute ethanol.
