Two patients have undergone to myocardial revasculairisation with venous segments, removed from the lower leg. In one patients, two anastomosis has been performed (left anterio-descending artery and first diagonal branch). In the another, the anastomosis has been completed by continuous over and over suture on the left anterior descending artery, obtuse marginal artery and left postero-lateral branch. There are no morbidity and operative mortality.

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.

Despite significant progress in medical therapy for ulcerative colitis, surgical intervention is still required in a portion of patients with ulcerative colitis. Ileal pouch-anal anastomosis has been commonly used in western countries, while ileorectal anastomosis may be appropriate in specific scenarios. The surgical decision should be made based upon the clinical situation and sufficient patient consent.

The aim of the study is to describe the technique of operation for Hirschprung's disease by a Soave modified procedure through the posterior sagittal approach, to propose the indications and to evaluate the early result. From January 2000 to April 2000, 26 children suffering from Hirschprung's disease were operated by this technique. There was no mortality during and after operation. The anastomosis leakage occurred in one patient. The posterior sagittal approach is a convenient and safe one in survey for Hirschprung's disease with the ganglionic segment involves in the rectum and sigmoid.

Magnetic compression anastomosis can compress tissues together and restore the continuity. Magnetic compression anastomosis mainly experienced three stages: magnetic ring, magnetic ring and column, and smart self-assembling magnets for endoscopy (SAMSEN). Nowadays, the magnetic compression anastomosis has been applied in vascular and different digestive tract surgeries, especially for complex surgery, such as anastomotic stenosis of biliary ducts after liver transplantation or congenital esophageal stenosis. Although only case reports are available at present, the advantages of the magnetic compression anastomosis includes lower cost, simplicity, individualization, good efficacy, safety, and minimally invasiveness. We are building a better technical platform to make magnetic compression anastomosis more advanced and popularized.

This paper describes some new concepts and new technologies about the current colorectal surgery, such as minimally invasive, bloodless surgery, no touch technique, and some new techniques of gastrointestinal anastomosis. Meantime, bloodless technique and closed resection in our clinic practice are introduced. These new concepts and new techniques widely used improve significantly the efficacy of colorectal surgery.

Methods of digestive tract reconstruction after distal gastrectomy include Billroth I, Billroth II and Roux-en-Y. Each of them has advantages and disadvantages respectively. Alkaline reflux gastritis (ARG) is one of the complications after distal gastrectomy, which is common after Billroth II. In the past 100 years, the ways of digestive tract reconstruction have been continuously improved and developed to prevent the occurrence of alkaline reflux gastritis, and Roux-en-Y is one of them. Still, there is a high incidence of Roux stasis syndrome resulting from Roux-en-Y, with impact on quality of life. Therefore, the appropriate reconstruction is needed urgently. Braun anastomosis was proposed in 1892 to lower the incidence of afferent syndrome. Because of its effect of diverting some alkaline digestive juice, it was applied to pancreaticoduodenectomy and distal gastrectomy. Some studies have proved its effect of diverting some alkaline digestive juice, but the diverted quantity was rarely shown. Besides, compared with Roux-en-Y, Billroth II with Braun anastomosis is safer and more convenient. Meantime it is likely to have benefits in aspect of preventing anemia and malnutrition. In order to provide evidence to clinical practice, this article summarizes the history and research advance of Billroth II with Braun anastomosis by reviewing previous reports.

A new anastomat for digestive tract operations, based on the magnetic compressive technique and mechanical transmission mechanism, is composed of a removable head and a reusable body. The head includes two parts: the proximal end can be fixed to the body, and the distal end could be used for performing a purse string suture. The procedure of anastomosis is similar to that of the stapler, and the anastomoses is established using a pair of magnetic rings. The instrument makes magnamosis more simple and feasible, and it would facilitate the clinical application. The body of the anastomat is reusable and the head could be replaced according to the clinical scenarios, these could reduce the medical cost. The magnetic rings would be excreted with the feces, and there is no foreign body response at last.

BACKGROUNDA new procedure of colonic anastomosis with a degradable stent has already been proven to be simple, feasible, and safe in our porcine model. In this study, we evaluated its impact on the colonic physiologic functions.

METHODSA total of 20 pigs were assigned randomly to either a stent anastomosis group (SA, n = 10) or a conventional anastomosis group (CA, n = 10). Colonic anastomosis with a degradable stent was performed in the SA group, and conventional hand-sewn anastomosis was performed in the CA group. Body weight, fecal weight, total colonic transit time, immunohistochemistry staining of interstitial cells of Cajal (ICC), plasma diamine oxidases (DAO) levels, and Western blotting analysis of occludin were evaluated before and after anastomosis.

RESULTSNo obvious diarrhea or constipation was observed in all pigs. No significant difference in body weight between the groups was detected at any time. Yet, the fecal weight was less in the CA group compared with the SA group on postoperative day (POD) 7. No observable colonic paralysis or retention occurred. For total colonic transit time, there was no significant difference between the two groups at any time or among different time points in the same group. The integrated optical density of ICC showed no significant difference on either POD 14 or 30. The plasma DAO levels were remarkably elevated after surgery, and began to decrease since POD 3. However, there was no significant difference between both two groups in plasma DAO levels at any time either. For both groups, the expression of occludin was not significantly different from their pre-surgery level on either POD 14 or 30.

CONCLUSIONSAccording to these results, this procedure with a degradable stent was supposed to be the same as the conventional hand-sewn procedure in their impact on the colonic physiologic functions.
