“…This suture reinforcement in the stapling line is also recommended by other authors and can be performed with additional stapling or with manual suturing over the area of air leakage [5,23,25]. Complementing the staple line with other surgical sutures or devices could guarantee better resistance at supraphysiological levels of ventilatory pressure [26][27][28]. However, this was not evaluated in our study.…”

Pulmonary loborraphy can be performed using manual sutures and staples, although other methods, such as tissue adhesives, are also cited in the veterinary literature. Although the surgery is well tolerated in the canine species, failure in pulmonary aerostasis is still a reality since all the methods described so far eventually lead to air leakage after the use of the partial lobectomy technique in the lungs. Within this context, the aim of this research was to compare the effectiveness of different hermetic sealing methods after partial lobectomy of the right caudal lung lobe (RCLL) in dogs. 30 cadavers models were divided in 6 groups: G1—cobbler suture associated with simple continuous; G2—overlapping continuous suture associated with simple continuous suture; G3—Ford interlocking suture; G4—Stapling device; G5—Tissue glue (cyanoacrylate). After performing the sealing techniques, the lungs were submerged in water and inflated with oxygen at positive ventilatory pressures at physiological (up to 14.7 mmHg, which is equivalent to up to 20 cmH2O) and supraphysiological levels (above 14.7 mmHg) to evaluate the performance of the sealing methods. At physiological ventilatory pressure levels, there was no difference between groups. Sealing with surgical glue was superior to interlocking sutures and stapling devices at supraphysiological levels of ventilatory pressure.

“…These results are in accordance with those obtained by various authors. (9)(10)(11)(12)(13)(14) The incidence of fistulas has also been less frequent after mechanical suture, (15,16,26) although some authors have found the frequency of this complication to be higher. (17,27) The rupture pressure values obtained by various authors suggest that the process of cicatrization can have a beneficial effect on the increased resistance to pressure.…”

“…Studies comparing manual and mechanical sutures of the bronchial stump show that the latter is more resistant on post-operative day 14, (9,10) that it is more resistant from post-operative day 1 to post-operative day 14, (11)(12)(13) especially when covered with bovine pericardium and biological glue, (14) and that it presents a lower incidence of BPF. (4,6,14,15) It is accepted that, although mechanical suture is safe, easily performed, and rapid, it is not totally free of complications.…”

Objective: To compare the resistance of manual suture with that of mechanical suture immediately after the suture of the left bronchial stump of dogs submitted to pneumonectomy. Methods: A total of 15 mixed-breed dogs of both genders, each weighing between 8 and 23 kg, were randomly divided into 2 groups. In group I (n = 7), the bronchial stump was sutured manually (the Sweet method) and, in group II (n = 8), it was stapled. Immediately after the closure of the bronchial stump, the intratracheal pressure was progressively increased in a controlled manner. Results: The mean rupture pressure of the bronchial stump suture line was 33.71 mmHg in group I and 89.87 mmHg in group II (p < 0.01). Conclusion: These data allowed us to conclude that mechanical suture of the bronchial stump, submitted to pressure immediately after closure, is more resistant than is manual suture in dogs submitted to pneumonectomy.

Background: Pulmonary loborraphy can be performed using manual sutures and staples, although other methods such as tissue adhesives are also cited in the veterinary literature. However, despite the wide availability, no efficient suture material has yet been recognized that is completely safe in preventing any air leakage, a complication that is heavily investigated in medicine and not uncommon in veterinary medicine, despite the few studies and reports in dogs. Although the surgery is well tolerated in the canine species, failure in pulmonary aerostasis is still a reality, since all the methods described so far eventually lead to air leakage after the use of the partial lobectomy technique in the lungs. Within this context, the aim of this research was to compare the effectiveness of different hermetic sealing methods after partial lobectomy of the right caudal lung lobe (RCLL) in dogs. Using 30 cadaver models of canine lungs obtained immediately after death. The 30 cadavers models were divided in 6 groups: G1 - cobbler suture associated with simple continuous; G2 - overlapping continuous suture associated with simple continuous suture; G3 - Ford interlocking suture; G4 - Stapling device; G5 - Tissue glue (cyanoacrylate). After performing the sealing techniques, the lungs were submerged in water, inflated with oxygen at positive ventilatory pressures at physiological (20 cmH2O) and supraphysiological levels (above 20 cmH2O) to evaluate the performance of the sealing methods and to asses the level of ventilatory pressures at which air leakage occur. Results: At physiological ventilatory pressure levels there was no difference between groups. However, when evaluating such methods at ventilation pressure levels above 20 cmH2O, it was found a superiority of G5 over G3 and G4. Conclusion: Manual sutures, as well as staples and synthetic tissue glue were able to promote aerostasis after partial lobectomy of the RCLL at physiological ventilatory pressures. Sealing with surgical glue was superior to Ford interlocking suture and stapling device at supraphysiological levels of ventilatory pressure. This study supports the efficay of all manual, mechanical sutures and synthetic glue sealant when used after partial lobectomy in dogs.
