Mechanic sutures represent an enormous benefit for digestive surgery in decreasing postoperative complications. Currently, the advantages of motorized stapler are under evaluation.
To compare the efficacy of mechanic versus motorized stapler in gastric surgery, analyzing rate of leaks, bleeding, time of stapling, and postoperative complications.
Ninety-eight patients were submitted to gastric surgery, divided into three groups: laparoscopic sleeve gastrectomy (LSG) (n=47), Roux-en-Y gastric bypass (LRYGB) (n=30), and laparoscopic distal gastrectomy (LDG) (n=21). Motorized staplers were employed in 61 patients. The number of firings, number of clips, time of total firings, total time to complete the surgery, and postoperative outcome were recorded in a specific protocol.
Patients submitted to LSG, LRYGB, and LDG recorded a shorter time to complete the procedure and a smaller number of firings were observed using motorized stapler (p<0.0001). No differences were identified regarding the number of clips used in patients submitted to LSG. In the group that used mechanic stapler to complete gastrojejunostomy, jejuno-jejuno-anastomosis, and jejunal transection, it was observed more prolonged time of firing and total time for finishing the procedure (p=0.0001). No intraoperative complications were found comparing the two devices used. Very similar findings were noted in the group of patients undergoing LDG.
The motorized stapler offers safety and efficacy as demonstrated in prior reports and is relevant since less total time of surgical procedure without intraoperative or postoperative complications were confirmed.
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.
When finishing a continuous suture, often a thread segment is too short to be tied. In this situation, the knots are made with the aid of needle holders or hemostatic forceps, but the result may be unsatisfactory1,2,3. Another option is to fix it with another thread, which is tied with the short thread, increasing the cost of the operation.
The use of an auxiliary thread to facilitate the making the end knot of a continuous short-threaded suture has been used by the author for over 40 years with good results. It is likely that other surgeons have also discovered this tactic and use it, but the author has not found published information and has only disclosed it personally during the operative acts.

In high-income countries, morbid obesity is a growing health problem that has already reached epidemic proportions. When performing a laparoscopic gastric bypass several operative methods exist.
To describe the institutional experience using a knotless unidirectional barbed suture (V-Loc 180/Covidien, Mansfield, MA) to create a hand-sewn gastrojejunostomy (GJ) and jejunojejunostomy (JJ) during bariatric surgery.
Evaluation of a case series of 87 morbidly obese patients who underwent laparoscopic gastric bypass with a hand-sewn gastrojejunostomy (GJA) and jejunojejunostomy (JJA) between 01/2015 and 06/2017. The patients were divided into two groups: in group I, GJA und JJA sutures were performed using the knotless unidirectional barbed suture; in group II, GJA and JJA were sutured with resorbable multifilament thread (Vicryl® 3/0 Ethicon, Livingstone, UK). The recorded data on gender, age, BMI, ASA score, operative time, postoperative morbidity, length of hospital stay, and reoperation, were analyzed and compared.
All procedures were completed laparoscopically with no mortality. The mean operative time was 123.23 (±30.631) in group I and 127.57 (±42.772) in group II (p<0.05). The postoperative complications did not differ significantly between the two groups. Early complications were observed for two patients (0.9%) in the barbed suture group and for one patient (0.42%) in the multifilament suture group (p<0.05). In group I two patients (0.9%) required reoperation: on the basis of jejunojejunal stenosis in one patient, and local abscess near the gastrojejunostomy, without a leakage, in the other. In group II one patient (0.42%) required reoperation due to stenosis of the GJA. The duration of hospital admission was similar for both groups: 3.36 (±0.743) days in group I vs. 3.38 (±1.058) days in group II (p<0.05).
The novel anastomotic technique is a safe and effective method and can be applied to gastrojejunal anastomosis and jejunojejunal anastomosis in laparoscopic gastric bypass.
