VALIDITAS HADIS TENTANG JUAL BELI GHARAR
Authors: Hamnah Hamnah 
Published: January 2023

The Qur'an is a source of Islamic law that is Qath'I, where all of its people must obey the laws that exist in it and no one disagrees or refutes it. Hadith is a source of Islamic teachings, which is second to the Qur'an. From the point of view of the narration, it is clear that there is a difference between the Hadith and the Qur'an. For the Qur'an, all its narrations are mutawatir. While the narration of Hadith takes place in part mutawatir and partly takes place on a week. So starting from here arise various opinions in assessing the quality of hadith. Hadith, even though it is the second source of Islamic law, is still disputed by scholars about its validity to be used as a legal basis, especially those related to vague cases both in the fields of aqidah, worship and muamalah. Currently, what is being discussed a lot is about the validity of the hadith in terms of trade law (buying and selling), especially vague buying and selling (gharar) because it will have an impact on aspects of the sale and purchase results are halal or haram to be used (used and eaten). The validity of this hadith in terms of buying and selling gharar needs to be re-analyzed in terms of its narration, which is related to the sanad and matan aspects. Hadith can only be said to be the second source of Islamic law when its quality is valid, both in terms of sanad and matan. A hadith can only be said to be valid if it meets the criteria for the validity of the hadith sanad, namely: the chain is continued, the narrator is 'fair, the narrator is dhabit, avoids syaz and avoids 'illat. In addition to the validity of the sanad, the validity of the matan is also important to prove the quality of a hadith, according to the jurists, the rules of the validity of the matan hadith are: Not maqlub, not mudraj, not experiencing ziyadah al-Tsiqah, not mudhtarib and not mushahhaf and muharraf.

Summary. The purpose of the work is to conduct a cytological examination of swabs-imprints of experimental purulent wounds that have not healed for a long time, when treated with silver nanoparticles in comparison with 0.05 % Chlorhexidine solution.
Research materials and methods. The study of the features of the cytological picture of skin regeneration was carried out on 60 white non-linear laboratory rats.
Research results. The obtained results of the cytological examination of purulent wounds that did not heal for a long time indicate faster wound healing processes in the group using nanostructured silver compared to the control group: there was a faster decrease in the number of leukocytes in the field of view and the percentage of their destruction, faster activation of monocyte-macrophage cells series, the appearance of fibroblasts and epithelial cells and, as a result, a faster change in the types of cytograms from necrotic to regenerative.
Conclusions. It was established that the presented method of using nanostructured silver contributes to a better elimination of microbial insemination, leads to a significant decrease in the number of neutrophil leukocytes and leukocytes in the stage of destruction, an increase in the percentage of phagocytic leukocytes, fibrocytes, fibroblasts, endotheliocytes and epithelial cells, which indicates a better antibacterial and anti-inflammatory effect and indicates much faster processes of cleaning and regeneration of purulent wounds. The use of silver nanoparticles has significant advantages compared to traditional treatment with a 0.05 % solution of Chlorhexidine and is promising for use in the practice of purulent surgery.

Summary. Introduction. According to the opinion of a number of experts, acute biliary pancreatitis should be considered a combination of acute pancreatitis with chronic or acute diseases of the biliary tract.
Aim. To assess intraoperative morphological changes during laparoscopy in patients with acute biliary pancreatitis.
Materials and methods. We treated 65 patients with acute biliary pancreatitis who had isolated cholecystolithiasis. Forty-two patients had acute calculous cholecystitis, twenty-three patients had chronic calculous cholecystitis. All patients underwent laparoscopy, which included diagnostic and treatment stages.
Results. Signs of acute biliary pancreatitis were: serous fluid (6.2 %), fibrinous fluid (10.8 %), hemorrhagic fluid (41.5 %), fatty spots (7.7 %), mesenteric hemorrhagic edema of the large intestine (64.6 %), pancreas edema (23.1 %), omentum edema (50.8 %), vitreous edema of the hepatoduodenal ligament (36.9 %), enlarged gallbladder (60.0 %), destructive acute cholecystitis (9.2 %). When the head of the pancreas was damaged, we observed hemorrhagic fluid, hepatoduodenal ligament edema, an enlarged gallbladder, and acute cholecystitis. When the body of the pancreas was damaged, we observed serous fluid, fatty spots, mesenteric edema of the large intestine, and parapancreatic infiltrate. In the inflammatory process of the pancreas tail, we often observed fibrinous fluid in the abdominal cavity.

Summary. Goal. Develop tactics for diagnostic monitoring of traumatic liver injuries.
Materials and methods of research.The study is based on an analysis of 56 victims with liver damage. A set of studies, including clinical, laboratory, and instrumental methods, was used to examine victims with abdominal injuries.
Research results and their discussion.The tactics of treatment for patients were primarily determined by the results of ultrasound and CT scans. Diagnostic monitoring was carried out in several stages: the first immediately after hospitalization in the admission department or intensive care unit, then, as is, taking into account the data found during the initial examination. The decision to choose conservative tactics was made within the first 3 hours after admission to the clinic. In the future, the patient’s management tactics will be determined depending on the severity of his condition, volume of hydroperitoneum, the intensity of blood loss, and hemodynamic parameters. In the case of hematomas of the liver, in the absence of signs of hydroperitoneum and stable hemodynamics, conservative therapy was performed with dynamic instrumental control over the condition of the hematoma.
Conclusions. Predicting the outcome of liver damage largely depends on the correct choice of methods of instrumental diagnosis and consistency in the analysis of information obtained from dynamic monitoring. This makes it possible to predict the severity of the condition and tactics of the patient, expanding the indications for conservative therapy. Conservative tactics are allowed only with repeated instrumental monitoring.

Summary. The aim of the study was to improve the results of surgical treatment of patients with malignant neoplasms of the pancreas complicated by mechanical jaundice, as well as to prove the feasibility of combined treatment and staged approach to it using minimally invasive technologies.
Materials and methods of the study. The results of treatment of 112 patients with pancreatic cancer who were treated in the surgical department of the Municipal non-commercial enterprise of the Kharkov regional council «Regional Clinical Hospital» from 2018 to 2021 were analyzed. The age of the examined patients averaged (53,2 ± 12,7) (from 37 to 88 years), of which women — 43 (38,0 %), men — 69 (62,0 %). All patients were examined in the laboratory and instrumentally.
Results of the study. Mechanical jaundice was observed in 81 (72,0 %) patients. According to the classification of VE Smirnov (1974), in 16 (14,2 %) patients acute jaundice was observed, in 56 (50 %) — acute prolonged and in 40 (35,8 %) — chronic mechanical jaundice. Among the results of the study of the analyzed patients, the minimum level of total bilirubin in mechanical jaundice was 44 μmol/l, the maximum — 546 μmol/l. All patients with mechanical jaundice underwent endoscopic retrograde cholangiopancreatography. Eight (9,8 %) patients developed complications after endoscopic retrograde cholangiopancreatography: bleeding from a papillotomy wound (4), clinic of acute pancreatitis (3), injury of the posterior wall of the duodenum (1). In 2 cases, the procedure failed due to total obstruction of the large duodenal nipple. Among the 79 patients who managed to undergo endoscopic intervention, only 5 cases, according to the commission on cancer care, were recognized as resectable in the future.
Conclusions. Minimally invasive methods of restoring bile in mechanical jaundice caused by cancer of the pancreas are effective as independent treatment procedures, staged, which may precede laparotomy.

Published: January 2023

Summary. Differential diagnosis of cystic lesions of the pancreas remains one of the most problematic sections of abdominal surgery. Endoscopic ultrasonography is gaining more and more importance in the diagnosis and determination of treatment tactics of cystic lesions.
The goal is to determine the place of endoscopic ultrasonography in the diagnosis of patients with cystic lesions of the pancreas.
Materials and methods. Analyzed literary sources that were devoted to the use of endoscopic ultrasonography for the diagnosis of cystic lesions of the pancreas.
Results and their discussion. Endoscopic ultrasonography, thanks to its high resolution and the absence of interposition of air-containing organs, allows you to visualize both the characteristic features of the structure of the cystic tumor itself and the ductal system of the pancreas, as well as to evaluate the thickness of the cyst wall, the presence of intracystic membranes and a solid component, the nature of the contents, the number of cystic cavities in the lesions.
Conclusions. Endoscopic ultrasonography is a clarifying method of diagnosis, which should be used in all patients at the stages of examination, planning treatment tactics and choosing a surgical intervention method.
OPTIMIZATION OF SURGICAL TACTICS IN PATIENTS WITH POSTNECROTIC PANCREATIC CYSTS
Authors: Merkulov A. O. , Shevchenko O. M. 
Published: January 2023

Summary. The predominance of people of working age (21–60 years) among patients with pancreatic necrosis, the occurrence of permanent disability in a significant part of patients, high overall and postoperative mortality (20–85 %), due to various complications, turns the treatment of pancreatic necrosis into an important social problem. The frequency of formation of false cysts in acute pancreatitis is 5–16 %, and in destructive forms it increases to 60–80 %.
Materials and methods. The scope of endoscopic interventions in the treatment of 16 patients with pancreatic cysts of the pancreas directly depended on the preoperative findings and, first of all, on the presence of the connection of the cyst with the pancreatic ducts. Favorable conditions for endoscopic correction in the treatment of pancreatic pseudocysts were a small (less than 10 mm) distance between their cavity and the lumen of the gastrointestinal tract, minimal thickness of the capsule (no more than 2 mm), large dimensions (over 6 cm), as well as localization in the projection body and isthmus of the pancreas.
Research results. When analyzing the results of the treatment of complications of pancreatic necrosis, we formulated an algorithm for the rational choice of operative interventions. We believe that rational treatment is based on early diagnosis of PN complications, including hemorrhagic ones.
Conclusions. The use of the developed algorithm allowed us to reliably reduce postoperative mortality among patients of this category.

Summary. Introduction. Postoperative abdominal wall wound infevtions became significant problem om modern surgery impacting approximatly 110,800 patients in 2015.
Aim of study. Comparison of postoperative abdominal wall wound complications treatment methods in cancer patients.
Materials and method. 24 cases of patients with purulent-septic complications of postoperative wounds were analised. 10 (41,6 %) — men and 14 (58,4 %) — women. The average age of patients was 63,8±17,1 years. Patients were divided into two groups: a comparative group — 12 patients (routine treatment), and an experimental group — 12 patients, which was treated using the VAC system. Both groups received infusion and antibacterial therapy.
Research results. In cultures of wound contents, the following were found: (1) Staphylococcus aureus — 38,9 %, (2) Staphylococcus epidermidis — 19,5 %, (3) Enterococcus faecalis — 19,1 %, (4) Escherichia coli — 15,4 %, (5) Pseudomonas aeruginosa — 5,8 %, (6) Proteus vulgaris — 0,9 %, as well as (7) gram-positive aerobic and facultatively anaerobic pathogens — 0,4 %.
According to the results of bacteriological examination of the wound contents in the patients of the experimental group, the microbial count decreased statistically significantly (to 105-106, p>0,05) starting from the third day of treatment. In the comparative group — all indicators remained at the previous levels (108-109).
Conclusions. VAC-therapy appeared superior in postoperative abdominal wall wound complications treatment in cancer patients. VAC significantly reduces both duration of hospital stay and mortality.

Summary. Aim. To determine the influence of elastic compression on the venous and arterial velocity of the main blood flow of the lower limb and the skin microcirculation of the anterior part of the foot in patients with a decompensated form of postthrombophlebotic syndrome.
Materials and methods. 21 patient with post-thrombophlebotic syndrome in the stage of decompensation participated in the study. Among them were 12 (57 %) women and 9 (43 %) men. The average age of the patients was (58.5±6.4) years. All subjects of the study were measured for the ankle-brachial pressure index, deep femoral-popliteal index, regional perfusion index, tcpO2, tcpCO2, arterial blood flow velocity in the femoral artery, and venous blood flow velocity distal to the saphenofemoral junction. After the measurements, the following measurements were performed after using elastic medical knitwear of different compression classes.
Research results. With I class compression, the venous blood flow rate was (0.064±0.007) (p=0.0001). The venous velocity of the femoral blood flow significantly decreased, on average, by 7.4 times compared to the initial conditions when using class IV compression (p=0.0001). values of tcpCO2 increased significantly already at the 1st compression class. (p=0.0001) and continued to increase until the end of the study. Analyzing the changes in tcpO2 and tcpCO2, it was established that at the 3rd compression class, there was a cross between the oxygen and carbon dioxide tension indicators, which was accompanied by the predominance of tcpCO2 pressure over tcpO2 at the next increase in the compression class.
Conclusions. The arterial blood flow rate decreased by 8.5 times compared to the input data at the maximum pressure of the fourth compression class (p=0.0001). Venous velocity of blood flow in the femoral vein at the maximum pressure of elastic compression decreased venous velocity by 7.4 times compared to the initial normal (p=0.0001). tcpCO2 significantly increases at compression of 15 mmHg (p=0.0001).

Summary. The aim of the study. Based on the analysis of the nature and course of postoperative complications in the treatment of patients with lung cancer, to improve the results of surgical treatment of this category of patients.
Materials and methods. The results of the analysis of postoperative complications of 363 patients with lung cancer who were treated in the oncological department of the thoracic cavity of the clinic of the Communal Non-Commercial Enterprise «Regional Center of Oncology» in Kharkiv for the period from 2017 to 2021 are presented. There were 234 men (64.6 %) , women - 128 (35.4 %), the age of patients ranged from 43 to 84 years, the average age was (59.8±2.4 years). All patients underwent radical surgery for primary lung cancer. Lobectomies were performed most often. In this volume, 296 patients were operated on, which was 81.5 %. Pneumonectomy was performed on 51 patients, which was 14.1 %. Anatomical segmentectomy was performed in 16 patients (4.4 %). Postoperative complications and factors causing them were analyzed.
Research results and their discussion. The main complications typical for the postoperative period of lung cancer patients are highlighted. Complications in the postoperative period occurred in 10.5 % of patients. Complications related to failure of bronchus stump sutures and tracheobronchial tree anastomoses occurred in 8 patients (2.2 %). In two patients, this led to the development of pleural empyema and death.Thanks to early diagnosis, 4 patients underwent rethoracotomy, bronchus stump suturing, resection or final pneumonectomy.
Cardiovascular complications (acute myocardial infarction, acute cardiovascular failure, stroke, pulmonary embolism) were found in 5 patients (1.4 %). 3 patients died of stroke, acute myocardial infarction and acute cardiovascular failure. Two patients survived, and one of them was diagnosed with Pulmonary embolism (PE), COVID-19 and bilateral pneumonia.
Postoperative mortality was 2.5 % (9 patients died). Two patients (0.6 %) died from failure of the bronchus stump sutures, which led to empyema of the pleura. Two patients (0.6 %) died from the consequences of intrapleural bleeding. Another 2 (0.6 %) patients died of acute myocardial infarction. One patient each (0.3 %) died of stroke, postoperative pneumonia, and pericux abscess, which led to empyema of the pleura.
Conclusions. The surgical method of treating patients with lung cancer remains the main one despite the number of postoperative complications, the majority of which are «non-surgical». Analysis of the nature and course of postoperative complications in the treatment of patients with lung cancer, and the improvement of the method of determining functional operability, made it possible to reduce the frequency of complications and form a concept for improving the results of surgical treatment of this category of patients.
