Tracking pylorus in ultrasonic image sequences is an important step in the analysis of duodenogastric reflux (DGR). We propose a joint prediction and segmentation method (JPS) which combines optical flow with active contour to track pylorus. The goal of the proposed method is to improve the pyloric tracking accuracy by taking account of not only the connection information among edge points but also the spatio-temporal information among consecutive frames. The proposed method is compared with other four tracking methods by using both synthetic and real ultrasonic image sequences. Several numerical indexes: Hausdorff distance (HD), average distance (AD), mean edge distance (MED), and edge curvature (EC) have been calculated to evaluate the performance of each method. JPS achieves the minimum distance metrics (HD, AD, and MED) and a smaller EC. The experimental results indicate that JPS gives a better tracking performance than others by the best agreement with the gold curves while keeping the smoothness of the result.

Alimentary tract duplications are a rare congenital malformation. They can present with varied symptoms owing to the locality of the duplication, along the gastrointestinal tract. Out of these duplications, the ones along the pylorus are the most rare. These are usually only diagnosed intraoperatively, as it is not a common differential on imaging due to its rarity. In lieu of the literature currently available, pyloric duplication cyst can present anytime from 1 week of age to 5 years, with some cases being detected antenatally due to the prevalence of regular antenatal scanning. Surgery remains the main stay of treatment with the goal of complete excision of the cyst and complete removal of the cyst mucosal lining. We report the case of a 5-year-old girl, which to our knowledge is the first ever reported case from Karachi, Pakistan.

The rate of return to normal of the pylorus muscle in infantile hypertrophic pyloric stenosis was measured by ultrasound, using a simple pyloric volume calculation and a pyloric muscle index. The muscle hypertrophy took from two to 12 weeks to resolve.

The gastric emptying of a liquid (5% dextrose) and a digestible solid (liver) were studied in 8 dogs with an intact stomach, after pylorectomy, after antrectomy, and after distal (Billroth I) gastrectomy. Pylorectomy and particularly Billroth I gastrectomy resulted in more rapid gastric emptying of the liquid. With an intact stomach, the digestible solid was broken down predominantly (93.8%) into very small particle size (less than 0.15 mm) before being passed into the duodenum. This ability was largely preserved after both pylorectomy or antrectomy. Billroth I gastrectomy resulted in the small bowel being presented with much larger particles of a digestible solid than if the antrum or the pylorus, or both, were preserved. After excision of both the antrum and the pylorus, 38.2% of the liver emptied in particle size greater than 1 mm as opposed to 2.5% from the intact stomach, 4.9% after pylorectomy, and 6.1% after antrectomy. Thus, both the pylorus and the antrum can control the gastric emptying of both a liquid and a digestible solid.

BACKGROUND
Fine anatomical knowledge enables us to use safer laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG). Detailed anatomical knowledge of the infra-pyloric vein (IPV) remains obscure. In this study, the aim was to classify the IPV vessel flow.
METHODS
From April 2009 to November 2012, 43 patients with clinical T1 gastric cancer underwent LAPPG with preservation of IPV. Operative videos were retrospectively reviewed, and an anatomical classification of IPV was proposed.
RESULTS
The IPV flow came into the right gastro-epiploic vein (RGEV) and/or the anterior superior pancreaticoduodenal vein (ASPDV). The IPV anatomical flow pattern was classified according to the following 4 types: Type I, the IPV more than 2 flow into RGEV; Type IIa, only 1 IPV into RGEV without into ASPDV; Type IIb, one IPV flow into RGEV and one flow into ASPDV; Type III, IPV only into ASPDV. The proportion of each type was 39.5% (17/43) in Type I, 30.2% (13/43) in Type IIa, 14% (6/43) in Type IIb, and 16.3% (7/43) in Type III.
CONCLUSIONS
The anatomical flow pattern of the IPV was described. It would be beneficial to improve the anatomical knowledge of the IPV for more elaborate and safer lymph node dissection during laparoscopic gastrectomy.
