ABSTRACT  
Original Article  
Aim. This study was done to determine the feasibility and effectiveness of the proposed  
method of thoracoscopic hemostasis and aerostasis. Methods. The study included 85  
patients operated for bullous lung disease, closed chest injury and penetrating chest  
wounds in the Lung and Mediastinum surgery department of the Republican Specialized  
Scientific and Practical Medical Center of Surgery named after Academician V.Vakhidov for  
the period from 2015 to 2019. Total of 33 patients made up the main group: thoracoscopy  
using the proposed technique and 52 patients for the comparison group: thoracoscopic  
aerostasis was performed using known methods. In 21 (40.4%) cases of comparison group, we  
performed video-assisted thoracoscopic (VATS) excision and suturing with pleurodesis; in 14  
(26.9%) cases VATS with stitching of a lung wound. VATS excision and flashing of bullae of

the lung using a stapler was performed in 19.2% (10 of 52) cases of the comparison group and Keywords  
24.2% in the main group, where all VATS were supplemented with Geprotsel gel application.  
Results. Using the Geprotsel in VATS interventions allowed to reduce the necessity of lung  
tissue stitching from 67.7% to 27.3%, respectively, to limit excision in 36.4% of patients, to  
achieve complete tightness after hardware stitching (χ2 - 17.304; Df=3; p<0.001), which  
generally leveled the risk of postoperative pneumonia and impaired hemostasis.  
Recommendation. We suggest that applying Geprotsel gel during VATS for lung tissue  
damages allows to reduce the application of additional sutures, improve the efficiency of  
minimally invasive operations with a decrease in the frequency of postoperative disorders of  
aero- and hemostasis.

INTRODUCTION  
The number of complications in thoracoscopic lung surgery associated with the development of postoperative  
intrapleural bleeding and leakage of the pulmonary parenchyma, as well as with a violation of the tightness of  
the sutured bronchus stump, remains significant and does not have a noticeable downward trend [1]. Under  
conditions of persistent pneumothorax, prerequisites are created for the development of infectious  
complications, the formation of a persistent residual cavity, which, in turn, may require repeated interventions  
or prolonged drainage [2].  
Some studies showed that air leakage occurs immediately after surgery in 28-60% of patients who  
undergo conventional lung resections, including lobectomy and smaller resections [3]. On the 1st day after  
surgery, air leakage is observed in 26-48% of patients; on the 2nd day, air leakage is present in 22-24% of cases;  
on the 4th day - in 8% of cases [4]. The National Emphysema Treatment Trial assumes that air leakage occurs at  
some point in the postoperative period in 90% of patients undergoing bilateral procedures with both  
thoracotomy and thoracoscopy, with average air leak duration of 7 days, and 12% of patients had a constant air  
leak even 30 days after surgery [5, 6].  
To achieve adequate hemoaerostasis - reliable sealing of the resection line - various methods of  
strengthening the wound surfaces of the lung are used in clinical practice: laser exposure, plasma factors,  
ultrasound, electrical coagulation, applying synthetic and biological adhesives to the surgical wound,  
application of adhesive collagen plates and synthetic materials [7, 8].  
This study aimed to determine the feasibility and effectiveness of the proposed method of thoracoscopic  
hemostasis and aerostasis.

MATERIAL AND METHODS  
The study included 85 patients operated in the Lung and Mediastinum surgery department of the Republican  
Specialized Scientific and Practical Medical Center of Surgery named after Academician V.Vakhidov (Tashkent,  
Uzbekistan) for the period from 2015 to 2019. Total of 33 patients of whom made up the main group  
(thoracoscopy using the proposed technique) and 52 patients considered as the comparison group  
(thoracoscopic aerostasis was performed using known methods).  
The study included patients with the following nosologies: bullous lung disease was diagnosed in 62.4% of  
cases, closed chest injury - 21.2%, penetrating chest wounds - 16.5% of cases.  
Surgery was performed as the main treatment. Video-assisted thoracoscopic (VATS) excision and suturing  
with pleurodesis was performed in most cases of comparison group (40.4%; 21 out of 52). The next most frequent  
surgical intervention was VATS with stitching of a lung wound (26.9%; 14 out of 52). VATS excision and flashing of  
bullae of the lung using a stapler was performed in 19.2% (10 of 52) cases of the comparison group and 24.2% in the  
main group, where all VATS were supplemented with Geprotsel gel application. The following operations were  
also performed in the main group: VATS excision of bullae of the lung with application of Geprotsel gel [9] (24.2%),  
VATS with application of Geprocel gel on the wound of the lung (21.2%)  
Ethical approval  
The review board and ethics committee of RSCS named after acad. V.Vakhidov approved the study  
protocol and informed consents were taken from all the participants.  
Statistical analysis  
The obtained results were subjected to the statistical processing with the using the standard package of  
Microsoft Excel 2010 software by the method of variation statistics with the estimation of indexes’ values  
(M±m).  
RESULTS AND DISCUSSION  
The most frequent complications of VATS were hemostasis and aerostasis disorders and, as a result,  
recondensing hemothorax and pneumothorax. Comparative analysis of complications frequency after VATS in  
comparison groups is presented in Table 1. Thus, at the comparative analysis of the complications frequency  
after VATS it was noted that only 3 (5.8%) patients of the control group had a recurrence of bleeding, while one  
of them had a recurrence of hemothorax (1.9%). Violations of aerostasis were registered in one (3.0%) case in the  
main group patient and in 6 (11.5%) patients from the comparison group. Pneumothorax relapse was only  
reported in one (1.9%) patient from the comparison group.  
Exudative pleuritis was also observed only in 3 (5.8%) patients from the comparison group. Thus, the  
frequency of complicated course in the control group significantly exceeded these parameters in the main  
group (9 vs. 1) with the difference reliability (criterion χ2) - 3,964; Df=1; P=0.047.

Out of 31 patients with bulla in the comparison group, a bulla rupture less than 5 cm occurred in 21  
patients and 10 patients with bulla were over 5 cm in size. At the same time, pneumonia after aerostasis was  
noted in 4 (12.9%), 2 (9.5%) with bull less than 5 cm and 2 (20.0%) with bull more than 5 cm. In the main group of  
this type of complication in 22 patients (8 patients with bulla more than 5 cm and 14 patients with bulla less

than 5 cm) with bull disease was not noted (criterion χ2 - 3.918; Df=1; P=0.048). Hemostasis disorder was noted  
in only one (10%) patient from the comparison group with a bulla size greater than 5 cm.  
When considering the technical aspects of HTS performance at the break of the bulla (Figure 1), it was  
noted that the use of gel composite material allowed in 36.4% of cases in the main group to limit the bulla  
excision without piercing the wound surface, while in the comparison group in 67.7% of cases the bulla excision  
was necessarily complemented by piercing the wound surface. Sealed hardware piercing was practically  
comparable in the comparison groups and was required in 8 (36.4%) cases in the main group and in 8 (25.8%)  
comparison groups. Additional sewing after the mechanical stitching was performed in two (6.5%) patients  
from the comparison group.  
The next comparative analysis in the compared groups depending on the reason for which VATS  
interventions were performed was the analysis of treatment results in case of lung injury (Figure 2). So, from 11  
patients of the main group after VATS, in one case (9.1%) there was a pneumonia and there were no cases of  
hemostasis disturbance, whereas, from 21 patients of the comparison group in 2 cases there was a pneumonia  
(9.5%) and in 2 cases (9.5%) hemostasis disturbance.

When considering the technical aspects of VATS in the lung injury (Figure 3), it was noted that in 36.4% of  
cases in the main group the use of gel composite material allowed achieving good results without piercing the  
wound surface, while in the comparison group in 33.3% of patients the effectiveness of hemostasis and  
aerostasis was achieved by electrocoagulation. Hermetic suturing of the lung wound was practically  
comparable in the comparison groups and was required in 6 (54.5%) cases in the main group and in 10 (47,6%)  
cases in the comparison group. Additional suturing after mechanical suturing was performed in one (9.1%)  
patient from the main group and in 4 (19.0%) patients from the comparison group.  
One of the evaluation criteria that determine not only the effectiveness of manipulations with VTS  
interventions, but also the quality of life of the patient is the duration of drainage of the pleural cavity and  
drainage.  
Table 2 shows the duration of pleural cavity drainage in comparable groups. Thus, during two days the  
pleural cavity drainage was required in 31 (93.9%) patients of the main group and in 42 (80.8%) patients from the  
comparison group. The pleural cavity drainage was required for three days in 1 (3.0%) patient from the main  
group and in 1 (1.9%) patient from the comparison group. From 4 to 5 days and from 6 to 7 days drainage was  
observed only in the comparison group patients: 4 (7.7%) and 3 (5.8%) patients, respectively. Drainage was  
prescribed for 2 (3.8%) patients from the comparison group.  
Summary results of VATS interventions in comparison groups are presented in Fig. 4. As can be seen from  
the diagram, complications were noted in only 3.0% of patients in the main group versus 17.3% in patients from  
the comparison group; pleural puncture (1.9%) and thoracoscopy for hemothorax (1.9%) were required only in  
patients of the comparison group. Only patients (3.8%) from the comparison group were also discharged with  
drainage.

CONCLUSION  
The use of Geprocel gel during VATS interventions reduced the need for flashing of lung tissue after excision  
from 67.7% to 27.3%, respectively, limited to excision in 36.4% of patients, to achieve complete tightness after  
hardware flashing (χ2 - 17.304; Df=3; p<0.001), which generally ensured the risk of postoperative pneumorrhea  
and hemostasis, reducing the overall frequency of all complications from 16.1% to 0% (χ2 - 3.918; Df=1; p=0.048).  
In case of wound damage of the lung tissue application of the composite material in the form of gel in the  
course of VATS interventions allows to improve the tightness of primary sutures from 71.4% to 85.7%,  
respectively, to reduce the probability of additional sutures from 28.6% to 14.3%, and in general to improve  
the efficiency of mini-invasive operations with a decrease in the frequency of postoperative manifestations of  
air and hemostasis abnormalities from 19.0% to 9.1%. The developed of VATS-technique for aero- and  
hemostasis abnormalities in case of pulmonary tissue injuries by means of local application of composite  
material in the form of a gel by means of the suggested delivery device allowed to reduce the frequency of the  
mentioned complications in the postoperative period from 17.3% to 3.0%, to reduce the necessity of prolonged  
drainage of the pleural cavity from 19.2% to 6.1%, to level out the necessity of repeated mini-invasive  
manipulations (3.8% in the comparison group) and, accordingly, to increase the share of patients without  
complications.
