Trichobezoars (formations of hair balls that can not pass through the pyloric valve) are responsible of some of deaths observed in Angora rabbirs. A total of 160 trichobezoar deaths corresponding to 28.6% of total deaths were recorded during a reported period of five years. The highest mortality due to hair balls was recorded in 2001 (36.4 %) and was least in 1999 (9.4%). Of the four breeds, the highest trichobezoar death records were obtained in Russian Angoras and the lowest in German Angoras. Trichobezoars occur more frequently in winter months than other months. Besides trichobezoars, other causes of death recorded were pneumonia, suppurative pneumonia, peritonitis, rupture of stomach, gastroenteritis, cardiac failure and a small number of miscellaneous causes. In most of the cases, large, single trichobezoars were located in the stomach. The stomach contents of the trichobezoar deaths were mainly watery and scanty faeces and hard semisolid faeces. The ball obstructed the stomach occupying the opening of the pyloric valve. Pathomorphological lesions were noted in stomach, liver, lungs, heart and kidney.

Duodenal ulcer perforation is a common cause of peritonitis and is considered as one of the most catastrophic complication of duodenal ulcer. Medical management causes decrease rate of elective surgery for duodenal ulcer. However emergency operations for duodenal ulcer are on the rise. This study is aimed at comparing success rate between Omentopexy and omental plugging in emergency management of duodenal perforation. A prospective simple random study has been carried out for one year with 73patients. Omentopexy was done in 38 patients and 35 patients underwent omental plugging method. Omental plugging was associated with longer operative time but incidence of reperforation is less than Omentopexy. Mean hospital stay in Omentopexy group is higher than omental plugging group. Above all omental plugging is associated with less morbidity and mortality.
