BACKGROUND: Over the years, many sutures were developed and then abandoned. Until now was not found an ideal suture to the intestinal tract or other tissues in general, making the choice a difficult task. AIM: To evaluate, macroscopically and microscopically, the healing process of intestinal anastomoses in dogs using polyglecaprone 25, polyglactin 910 and cotton sutures. METHODS: Twenty adult male dogs were operated on and underwent to three small bowel anastomosis using the technique with submucosal sutures. Were used three threads and the anastomoses were evaluated at different postoperative periods - group I - three days; group II - seven days; group III - 14 days and group IV - 21days. Macroscopic analysis was to assess the presence or absence of peritonitis, aspect of the anastomosis and adhesions. Histological studies of the anastomoses, using hematoxylin and eosin and Masson's trichrome analyzed the exudative inflammation, granulomatous inflammation, the mucosal epithelial coating and collagen fibers. RESULTS: The macroscopic analysis showed good coaptation of the edges with a moderate degree of adhesion between the intestines and omentum three to 21 days after surgery. The microscopic evaluation revealed exudative inflammation with neutrophils and fibrin, which ranged from mild to moderate until the 14th day; granulomatous inflammation with macrophages, multinucleated giant cells and epithelioid cells were more evident at 14th day for the cotton, presence of granulation tissue (fibroblasts) and collagen fibers, a moderate way, from the 7th for the three threads. CONCLUSION: All three threads showed similar behavior and thus they can be indicated for anastomoses of the small intestine.
Fifty-five percent of Americans aged 50-65 are submitted to colonoscopy. For over 65-year, this number increases to 64%. In Brazil, it is forecast that the population submitted to colonoscopy will grow, even though inadequate preparation is still a major problem.
To analyze the quality of a new intestinal preparation technique, Aquanet EC-2000®, compared to oral Mannitol solution.
This prospective longitudinal study enrolled 200 patients with indication for colonoscopy. The sample was randomly allocated to two groups of 100; one group received Aquanet EC-2000® to prepare for colonoscopy and the other Mannitol solution. The Boston scale was used to analyze the results.
As expected both preparations produced similar results with the bowel cleansing of the different regions of the colon being classified as Boston scale 3 (excellent) in most patients (p>0.05).
The results of bowel preparation using Aquanet EC-2000® were similar to using Mannitol solution.
There have been an increasing number of articles that demonstrate the potential benefits of minimally invasive liver surgery in recent years. Most of the available evidence, however, comes from retrospective observational studies susceptible to bias, especially selection bias. In addition, in many series, several modalities of minimally invasive surgery are included in the same comparison group.
To compare the perioperative results (up to 90 days) of patients submitted to total laparoscopic liver resection with those submitted to open liver resection, matched by propensity score matching (PSM).
Consecutive adult patients submitted to liver resection were included. PSM model was constructed using the following variables: age, gender, diagnosis (benign vs. malignant), type of hepatectomy (minor vs. major), and presence of cirrhosis. After matching, the groups were redefined on a 1:1 ratio, by the nearest method.
After matching, 120 patients were included in each group. Those undergoing total laparoscopic surgery had shorter operative time (286.8±133.4 vs. 352.4±141.5 minutes, p<0.001), shorter ICU stay (1.9±1.2 vs. 2.5±2.2days, p=0.031), shorter hospital stay (5.8±3.9 vs. 9.9±9.3 days, p<0.001) and a 45% reduction in perioperative complications (19.2 vs. 35%, p=0.008).
Total laparoscopic liver resections are safe, feasible and associated with shorter operative time, shorter ICU and hospital stay, and lower rate of perioperative complications.
