Mesh closure of epiploic foramen by ventral laparotomy in 17 horses with entrapment

BackgroundEpiploic foramen entrapment (EFE) of small intestine is a severe cause of strangulating small intestinal obstruction (SSI) with long-term survival seeming lower than for other causes of SSI in horses. Different techniques via laparoscopy or laparotomy for epiploic foramen (EF) closure have been developed.MethodsThis study describes a technique of peroperative mesh closure of the EF in clinical cases and their long-term follow up.ResultsIn the study period of 5.5 years, 36 horses were admitted to the clinic with EFE. Of these, 17 horses had peroperative mesh closure, with resection anastomosis in 4 cases and enterotomy in 4 other cases. Fifteen of these survived to discharge. Long-term follow-up (one to three years, median three years) was favourable in all 15 horses not showing recurrence of EFE nor other related signs of colic. Laparoscopic evaluation of the EF was performed in two cases and showed integration of the mesh. One horse was euthanased 3.5 years after mesh placement for an unrelated cause and the mesh was well adherent obliterating the EF.ConclusionMesh closure of EF during emergency coeliotomy did not cause short-term complications even in horses with resection or enterotomy and may reduce the risk of recurrence of EFE in horses.

Comparative analysis of the data on the structure of omental bursa

This essay is about the differences in the description of the upper story of the peritoneal cavity, the omental bursa and omental (epiploic) foramen, which connects the omental bursa (lesser sac) with the rest of the peritoneal cavity (greater sac). The difference in the description of the omental bursa causes misunderstanding during the study of the topic «The stories of the peritoneal cavity». The misunderstanding is especially well expressed when we teach the foreign students because there is a great difference in the description of the omental bursa in Russian and English literature. That is why we decided to analyze the data of the omental bursa in different literal sources. We analyzed 11 textbooks, 5 of the mare Russian and 6 of the mare English, most useful for the students during the preparing the material for Anatomy classes. The results are given in tables.
