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.

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.

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.

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.

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.

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.

Tracheoesophageal fistula (TEF) after prolonged intubation could present as chronic aspiration and could be mistaken as unilateral or bilateral vocal fold palsy, especially when there was combined posterior glottic synechia. We present a case of post-intubation TEF which was successfully treated with tracheal resection and anastomosis with primary esophageal closure. The accompanying posterior glottic web was treated by endoscopic technique of web lysis, with topical application of mitomycin C solution.

PURPOSE: A model and a program was developed for training surgeons in laparoscopic urethrovesical anastomosis in order to improve the laparoscopic suture technique for urologists with no previous experience. MATERIALS AND METHODS: The procedures were performed on a pelvic trainer using a videolaparoscopic unit. The program consisted of a simple suture, urethrovesical anastomosis with interrupted sutures, and urethrovesical anastomosis with continuous sutures. The trainees enrolled in this study were 5 residents from the urologic department who had little experiences in laparoscopic suturing. The trainees performed each procedure 10 times and the elapsed time was recorded. Univariate analysis of the general linear model was used to assess the significance of progression. RESULTS: In the first lesson of the simple suture, the mean elapsed time was 5.45+/-3.00 minutes (range 2.78-9.83minutes) and each trainee demonstrated a difference in the elapsed time for suturing. After the tenth lesson was complete, the mean elapsed time was 1.48+/-0.17 minutes (range 1.35- 1.70 minutes) and the time differences between each trainee decreased. In urethrovesical anastomosis with interrupted sutures, the mean elapsed time decreased from 24.07+/-3.97 minutes at the 1st lesson (range 16.13- 29.47 minutes) to 13.10+/-2.53 minutes (range 11.75-19.47 minutes) after 10 lessons. In urethrovesical anastomosis with continuous sutures, the mean time decreased from 39.61+/-3.60 minutes (range 34.41-45.71 minutes) after one lesson to 30.42+/-5.75 minutes (range 19.50-38.82 minutes) after 10 lessons. There were significant differences in the elapsed time up to the 2nd lesson compared with the 10th lesson in all procedures (p-value<0.05). CONCLUSIONS: The skills of the trainee can be improved by a model and a program for training laparoscopic urethrovesical anastomosis. In particular, urethrovesical anastomosis, in which many urologists find difficulty, may become more accessible using this model and program.

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.
