Side-to-side intestinal anastomosis is a surgical procedure where an incision is performed between two parallel segments of gut and then they are sutured together. The purpose of this paper is to investigate if the standard surgical practice diameter used in anastomosis leads to undesirable closed circulatory flows which may be harmful to the gut tissue. A finite element model for the chyme flow in a side by side anastomosis with realistic user configurable parameters is developed and solved in a wide range of situations. We analyze the flow crossing the anastomosis, the normalized pressure difference in the gut section and the streamlines that show the presence or absence of closed flow regions for a set of surgically feasible anastomosis diameter values. In contrast with the findings of simpler analytical models, closed flows do not appear in any of these cases. The study shows that the current standard surgical practice where the anastomosis diameter is similar to the gut diameter does not lead to undesirable effects predicted by some simple analytical models.

Organoid is a newly developed cellular there-dimensional culture system in recent years. Organoids have a three-dimensional structure, which is similar to that of the real organs. Together with the characteristics of self-renewal and reproduction of tissue origin, organoids can better simulate the function of real organs. Organoids provide a new platform for the study of organogenesis, regeneration, disease pathogenesis, and drug screening. The digestive system is an essential part of the human body and performs important functions. To date, organoid models of various digestive organs have been successfully established. This review summarizes the latest research progress of organoids of taste buds, esophagi, stomachs, livers and intestines, and prospects future application of organoids.

A case of tubular duplicatio of the ileum in a 2 months old infant was presented. This patient was admitted because of abdominal distention and poor general condition. Operation revealed long tubular duplicated blind intestine, measuring 57X5cm in size. The pathologic diagnosis confirmed duplication of the ileum. The patient was discharged without any complication on the 17 th postoperative day. A brief review of literature was made.

Hodgson's bats are critically endangered in South Korea. This study analyzed the concentrations of elements in liver, kidney, and intestine tissues from a Hodgson's bat found dead in the wild. The concentrations of essential elements followed the order Fe > Zn > Cu >Mn > Se in the three tissues. Hg was detected at the highest concentrations among the non-essential elements analyzed in the liver and kidney tissues, while As was the most highly concentrated non-essential element in the intestine. To the best of our knowledge, this is the first study of tissue element concentrations in Hodgson's bats.

We present the case of a patient with severe postoperative scarring from surgical treatment for gastroschisis, with the intestine located immediately under the dermal scar. Although many patients are unsatisfied with the results of scar repair treatment, few reports exist regarding severe or difficult cases involving the surgical repair of postoperative scar contracture. We achieved an excellent result via simulation involving graph paper drawings that were generated using computed tomography images as a reference, followed by dermal scar de-epithelialization. The strategy described here may be useful for other cases of severe postoperative scar contracture after primary surgery for gastroschisis.

9.Intestinal microorganisms and allergic diseases.
Journal of Clinical Otorhinolaryngology Head and Neck Surgery 2014;28(5):351-355
According to the 'hygiene hypothesis', the intestinal microbes would not only regulate local immune status, but also affect systematic immune homeostasis, which may play an important role in the pathogenesis of allergic diseases. This review will mainly focus on investigating the intricate relationships among intestinal microbes, immune system and allergic diseases. Multiple factors affecting gut microorganisms may influence the immune homeostasis directly and later become risk factors of allergic diseases. This point of view may pave the way for the design of new interventions to the diseases.
