LAPAROSCOPIC ANASTOMOSIS IN THE ATRESIA OF SMALL BOWEL

Introduction. A complete laparoscopic intestinal anastomosis remains a challenge for pediatric surgeons. The aim of the study is to demonstrate its effectiveness in patients with small bowel atresia. Material and methods. This article describes laparoscopic surgery in a patient with small bowel atresia of type I. During laparoscopy, stitches were placed on the blind end of the atresia segment of the intestine to stabilize the movable intestinal segment; the stitches were passed transdermally to the outside. The design of the laparoscopic anastomosis did not differ from that of the open technique proposed by Jannie Louw. At the final stage of the trial, the researchers assessed immediate and long-term results after this new surgical intervention. Results. Laparoscopic intervention for small bowel atresia of type I was performed on the second day of life. The surgery lasted for 75 minutes. No complications were registered during it. The enteral nutrition was started after the decrease in the rate of losses in the gastric tube lower than 10 ml / kg / day. It was on day 3 after the surgery. A gradual increase in the volume of feeding promoted patient’s transfer to the full enteral nutrition on day 7 after the surgery. Next day, the baby was discharged from the hospital. Early follow-up revealed no any signs of anastomosis failure. One-year follow-up revealed no signs of impaired intestinal transit too. Conclusion. It seems that the care of small bowel atresia has taken a significant step forward. Anastomoses constructed laparoscopically in such patients are not only a possible option, they have demonstrated their effectiveness and safety as well.

Analysis of pregnancy outcome after anastomosis of oviduct and its influencing factors

Background This study aims to investigate the influencing factors of pregnancy after laparoscopic oviduct anastomosis. Methods The data of 156 cases of laparoscopic oviduct anastomosis in our hospital were analyzed. Results The pregnancy rate decreased with age (P < 0.005). The pregnancy rate after six years of anastomosis was higher in those with ligation (P < 0.005). The postoperative pregnancy rate significantly increased in subjects with oviduct lengths of > 7 cm (P < 0.01). The pregnancy rate of isthmus end-to-end anastomosis was higher (P < 0.005). The pregnancy rate after bilateral tubal recanalization was higher than that after unilateral tubal recanalization (P < 0.005). The pregnancy rate after laparoscopic tubal ligation and laparoscopic anastomosis was higher than that of open tubal ligation and laparoscopic anastomosis (P < 0.005). Conclusion The pregnancy rate after laparoscopic oviduct anastomosis is higher in subjects below 35 years old, with a ligation duration of < 6 years, and a length of oviduct of > 7 cm, and those who underwent isthmus anastomosis and laparoscopic oviduct ligation and recanalization.

Multicenter Controlled Study of Intracorporeal Mechanical Side-to-Side Isoperistaltic Anastomosis versus Extracorporeal Anastomosis in Laparoscopic Right Hemicolectomy: HEMI-D-TREND-Study

Colorectal cancer is the second most frequent cancer in the Western world. A third of colorectal tumors are located in the right colon, and right hemicolectomy is the treatment in nondisseminated right colon cancer. The most serious complication of this procedure is anastomotic leak, which occurs in 8.4% of cases. At present, there is no standardized technique for laparoscopic ileo-colic anastomosis. In previous observational studies, intracorporeal side-to-side ileo-colic laparoscopic anastomosis has shown better results than extracorporeal anastomosis in terms of morbidity and mortality. It is known that randomized studies provide higher levels of evidence, but multicenter randomized controlled studies may imply a learning curve bias due to the differences in technical experience acquired at each hospital. As a result, we propose to carry out a prospective, controlled, nonrandomized TREND-study design (Transparent Reporting of Evaluations with Non-randomized Designs-TREND) in a large sample of 416 patients (208 per group) in order to assess the use of intracorporeal side-to-side ileo-colic laparoscopic anastomosis as the gold standard in right hemicolectomy.

Totally Laparoscopic Aortic Surgery: Comparison of the Apron and Retrocolic Techniques in a Porcine Model

This study evaluated the learning curve for a second-year general surgery resident and compared 2 totally laparoscopic aortic surgery techniques in 10 pigs: the transretroperitoneal apron approach and the transperitoneal retrocolic approach. Five end points were compared: success rate, percentage of conversion, time required, laparoscopic anastomosis quality, and learning curve. The first 3 interventions required an open conversion. The last 7 were done without complications. Mean dissection time was significantly higher with the apron approach compared with the retrocolic approach. The total times for operation, clamping, and arteriotomy time were similar. All laparoscopic anastomoses were patent and without stenosis. The initial learning curve for laparoscopic anastomosis was relatively short for a second-year surgery resident. Both techniques resulted in satisfactory exposure of the aorta and similar mean operative and clamping time. Training on an ex vivo laparoscopic box trainer and on an animal model seems to be complementary to decrease laparoscopic anastomosis completion time.
