Abstract. Introduction. In recent years, a method of surgical treatment of hemorrhoids by the method of ligation of hemorrhoidal arteries under Doppler control (THD technique), as well as with additional rectoanal reconstruction (HAL-RAR) has been developed and widely used. The aim of the study. The aim of our study was to compare methods of treatment of chronic complicated hemorrhoids stage II-III: classical Milligan-Morgan surgery, staple mucopexy according to Longo, as well as a combined technique: Doppler desarterization by HAL-RAR with additional removal of the external anodermal component. Materials and methods. In the clinic of coloproctology of Military medical: Clinical Center of the Southern Region of Odessa performed an analysis of three groups of patients for the period from 2011 to 2021, who underwent hemorrhoidectomy for complicated forms of hemorrhoids (bleeding, nodular prolapse, mucosal prolapse, anal fissure). All patients suffered from chronic complications of stage II or III hemorrhoids, with one or more of the above complications. Selected cases are divided into three groups: Group I (control) operations on Milligan-Morgan — 240 patients, including -64 women and 176 men; Distribution by age from 18 to 75 years; Group II staple hemorrhoidopexy for Longo — 276 patients, including 89 women and 115 men. Distribution by age from 18 to 72 years; Combined interventions using the wireless Doppler surgical complex Wi-3 HAL-RAR and additional removal of excess anoderm (from January 2019 to May 2021) operated on 53 patients, including 31 (58%) men and 22 (42%) women . Distribution by age from 28 to 62 years. Results and discussion. According to our data: bed day ranged from 1 to 8 days, mostly it was lower in group III — 1.3 (± 0.4) bed per day compared to 3.1 (± 0.8) in group II and 4.8 (± 1,7) in group III resorptive fever was not observed; the highest pain syndrome for VASH (average 7 points) in the group of patients of group I — compared with patients from group II (average 4 points) and patients of group III (average 2 points); the highest number of early postoperative complications was found in the group of patients operated on Milligan- Morgan: 1) acute urinary retention was observed in 43 cases (18%) of group I, compared with 38 cases (14%) of group II. The lowest number of cases of urinary retention was observed in group III — 2 cases (4%) (p <0.05). 2) postoperative bleeding from the wound was significantly more common in group I — 9 cases (3.75%), compared with group II — 6 cases (2.5%). No postoperative bleeding was observed in group III. 3) resorptive fever was most common in group I — 43 cases (18%) compared with group II - 33 cases (12%). Resorptive fever did not occur in group III (p<0.05). In all patients using the combined intervention HAL-RAR + excision of the external component of the anoderm, the pain was acquired by taking nonspecific anti-inflammatory drugs without the use of narcotic analgesics. No complications were observed. All patients noted no reduction in quality of life in the postoperative period. Conclusions. 1. Surgical treatment of hemorrhoids by the combined method of HAL-RAR + excision of the external component is a simple and effective method that in the postoperative period reduces the patient’s stay in the hospital, relatively lower in pain and the frequency of early postoperative complications. 2. HAL-RAR technology with excision of the outer component of the anoderm can be the operation of choice in the surgical treatment of chronic complicated hemorrhoids stage II-III.

Background/Aim. Esotropia is the most common manifestation form of strabism accompanied by refraction deviations and amblyopia. The aim of this prospective study was to present the outcomes of surgical treatment of esotropia in children and adolescents. Methods. Within the period from January 1st 2006 to February 1st 2007 at the Clinic for Ophtalmology, Military Medical Academy, Belgrade a total of 25 patients with esotropia (34 eyes) and previously corrected refraction anomaly and treated amblyopia were operated on. The patients were 4-19-year of age. All of the patients were submitted to a complete ophtalmologic and orthoptic examination prior to the surgery, and a month, three months and six months after the surgery. The surgery was performed under general anesthesia. Out of the total number of the patients nine were operated on both eyes, while 16 patients on one eye with amblyopia or frequent esodeviation. Nine patients were submitted to retroposition of the inner straight muscle, two to myectomy of the outer straight muscle, while in 14 of the patients a combination of retroposition and myectomy was performed. The patients were divided into three groups according to the preoperative angle at the distance and followed-up accordingly after the surgery. Deviation angle at the distance in the group I was 18-25 DP, in the group II 26-35 PD, while in the group III it was 36-60 PD. Results. The most numerous, group I (12 patients; 48%), a month following the surgery showed angle reduction by 55.58%, after three months 63.25%, and after six months 63.92%. The group II consisted of 8 patients (32%) showed angle reduction by 70.75% a month following the surgery, by 76% after three months, and by 79.12% after six months. The group III (5 patients; 20%) showed angle reduction by 72.20% a month following the surgery, 79.20 after three months, and 80.12% after six months following the surgery. Conclusion. The best postoperative outcomes after a month, three and six months were obtained in the group of patients with the highest esodeviation angle at the distance solved by the surgery on both eyes. Timely surgical treatment befell into major precondition for developing and maintaining the elements of binocular vision in the operated on patients. .

The purpose of the study was to investigate the efficacy of Mastodynon in terms of indications in elevated doses versus the standard dose. Materials and methods. Data were analyzed for 60 patients after surgical treatment of fibro-cystic mastopathy. Depending on the postoperative therapy received by the patients, they were divided into three groups. Group I (n = 20): patients were observed in accordance with the standards established in mammal practice and did not receive special agents that affect hormonal homeostasis. Group II (n = 20): In addition to observation, patients received Mastodynon® (1 tablet or 30 drops 2 times a day) for 6 months. Group III (n = 20): Patients were given for a post-operative rehabilitation Mastodynon® in a double dose (2 tablets or 60 drops 2 times a day) for 6 months. Results Surgical treatment without conservative therapy eliminates organic changes in the thoracic glands (GH), but hormonal disorders that have led to pathologic and histological changes in the tissues of GZ continue to exist for a long time and can lead to repeated nodal formations. In group І, 25% of patients within 2 years performed repeated sectoral resections on recurrence of nodule formation. In group І, 25% of patients within 2 years performed repeated sectoral resections on recurrence of nodule formation. The use of Mastodynon® in standard doses (group II) for postoperative rehabilitation contributes to a significant improvement in hormonal homeostasis (normalization of prolactin, estradiol and progesterone levels), a 24.7 mm decrease in the degree of cyclic mastodynia according to the visual analog scale (VAS), and the improvement of ultrasound scan Pictures of GZ in 75% of patients. The most pronounced effect of this rehabilitation approach after the surgical treatment phase was noted for the use of Mastodynone in doble doses (2 tablets or 60 drops 2 times a day) in Group III. In these patients, the degree of reduction of cyclic mastodynia was 30 mm for VAS and positive changes in the tissues of GH were noted in 85% of patients. However, the highest incidence of adverse events was also noted in Group III, although they were temporary in nature and did not require withdrawal or dose reduction. Conclusion. Despite the presence of short-term side effects and rapid rebounding in the double-dose Mastodynon® group, our study showed better results than standard doses, faster and more stable therapeutic effect. Taking into account the results obtained, it can be argued that the use of high doses of Mastodynon® may be recommended to patients for the treatment of mastopathy. For a more complete study of such an important aspect as the tolerability of high doses of Mastodynon®, it is advisable to conduct more extensive studies, taking into account the dosage form and the use of other drugs. Key words: mastopathy, postoperative rehabilitation, Mastodynon®, mastodynia.

Objective. To compare the efficacy of methods of miniinvasive palliative treatment of malignant hilar strictures with the jaundice syndrome. Materials and methods. Into the investigation 71 patients, suffering proximal obturation jaundice of tumoral genesis, were included. The patients were divided into three Groups: Group I - 26 patients, to whom external-internal suprapapillary cholangiostomy was done; Group II - 28 patients, in whom transcutaneous transhepatic antegrade endobiliary stenting was performed; Group III -17 patients, to whom endoscopic retrograde biliary stenting was accomplished. Results. Technical success in all the Groups have constituted 100%; clinical one - in 94.0%: in Group I - 96.2%, in Group II - 89.3%, and in group III - 82.4% (p>0.05). In Group I general rate of morbidity was lesser, including cholangitis and pancreatitis. The duration of cholangitis was lesser as well. Cumulative survival were the highest in Group of patients, to whom external-internal suprapapillary cholangiostomy was performed (135 days at average), while the least one - in Group of the patients, in whom endoscopic retrograde biliary stenting was done (90,6 days). In Group of patients, to whom transcutaneous transhepatic antegrade endobiliary stenting was performed, this index have constitited 101.2 days. Conclusion. In proximal strictures of biliary ducts of tumoral genesis on background of jaundice the priority method of palliative treatment must be external-internal suprapapillary cholangiostomy, while the second-line of surgical treatment must constitute transcutaneous transhepatic antegrade endobiliary stenting. Endoscopic retrograde biliary stenting owes the lowest priority.

Background. One of the reasons for the development of the “pincer” type of femoroacetabular impingement are various reorienting pelvic osteotomies, which are widely used in the treatment of children with developmental dysplasia of the hip (DDH).The aim of the study was to evaluate the frequency of formation of retroversion of the acetabulum after reorienting pubic-iliac, iliac-sciatic and triple pelvic osteotomies in children over 7 years old with DDH I–II degree according to Crowe.Material and Methods. The retrospective study is based on the results of radiometry of 60 patients (69 hip joints) at an average age of 11.6±2.9 years with DDH I–II degree according to Crowe who underwent surgical treatment in 2014-2016. The patients were divided into three groups of 20 patients each. Group I underwent an iliac osteotomy. Group II underwent an ilio-sciatic osteotomy. In group III patients, the acetabulum was reoriented by triple (pubo-ilio-sciatic) pelvic osteotomy. In addition to standard radiometry of the hip joints, the following indicators were evaluated: signs of acetabular retroversion (“cross-over”, “posterior wall”, “ischial spine”), as well as the index of acetabular retroversion (ARI).Results. The assessment of the main radiometric parameters of the spatial position and the correction value of the acetabulum was carried out at least 36 months after the surgical treatment. There were no statistically significant differences in the radiometric parameters of the spatial orientation of the acetabulum in group I and II patients (p>0.05), except for the degree of bone coverage, which was significantly higher in group II patients (p<0.05) than in group II patients, which indicated the presence of hypercorrection. In patients of group III, the values of the above-mentioned indicators varied within the physiological values. Retroversion of the acetabulum was observed in more than half of the patients in group I and in almost all patients in group II. In group III patients, acetabular retroversion was observed in only 3 patients.Conclusion. In the vast majority of cases, a double pelvic osteotomy (pubo-iliac and ilio-sciatic) leads to the formation of hypercorrection of the acetabular fragment and its retroversion in comparison with a triple pelvic osteotomy. The pathological orientation of the acetabulum, despite the achieved stability of the hip joint, can be a morphological substrate for the development of femoro-acetabular impingement and, as a result, coxarthrosis. In the treatment of children with DDH over 7 years old the operation of choice is a triple pelvic osteotomy.

Introduction: The predictive value of the platelet to lymphocyte ratio (PLR) has been demonstrated in several cardiovascular diseases. The aim of this study was to investigate the interest of the preoperative PLR as a predictor of 30-day postoperative outcome in patients with abdominal aortic aneurysm (AAA) undergoing open or endovascular surgical repair. Material and Methods: Two hundred twenty-four consecutive patients with infrarenal AAA were retrospectively included and divided into 4 quartiles according to the value of the preoperative PLR: PLR < 91.5 (group I), 91.5 < PLR < 120.8 (group II), 120.8 < PLR < 163.3 (group III), and PLR > 163.3 (group IV). Results: The AAA diameter was similar among the groups (54.9 mm vs 58.6, 57.5, and 58.7 mm; P = .4655). The proportion of symptomatic AAA and the procedural characteristics did not differ. Patients from group I and IV had significantly higher rates of all-cause postoperative complications compared to group II and III (55.4% and 64.3% vs 39.3% and 46.4%, respectively; P = .0478). The all-cause mortality tended to be higher in group I and IV (7.1% and 8.9% vs 0% and 3.6%, respectively; P = .1305). Conclusion: Extreme values of PLR are associated with a higher risk of complications following AAA surgical repair, suggesting its interest as a biomarker to evaluate the surgical risk.

Objectives. To study the effectiveness of layered dermatolipectomy and endoscopic fasciotomy in the surgical treatment of refractory venous trophic ulcers.Materials and methods. Patients (n = 105) of the C6 clinical class underwent crossectomy and short stripping. In group I (n = 35), free autodermoplasty of trophic ulcers with a perforated flap was performed. In group II (n = 36), shave therapy and autodermoplasty were performed. In group IIІ (n = 34), fasciotomy, shave therapy and autodermoplasty were performed. Long-term results of treatment were studied in the period from 1 to 12 months.Results. Complete healing of venous trophic ulcers was observed in group I at 49,4 ± 7,2, in II – at 31,4 ± 4,7, in III – at 32,1 ± 3,6 days сутки (t1-2 = 2,09; p1-2 = 0,049; t1-3 = 2,24; p1-3 = 0,024; t2-3 = 0,03; p2-3 = 0,763). Full engraftment of an autograft graft was recorded in 7 (19,4 %) patients of group I, in 27 (77,1 %) cases in group II and in 27 (79,4 %) patients of comparison group III (χ21-2 = 23,674; p1-2 = 0,001; χ21-3 = 25,173; p1-3 = χ22-3 = 0,052; p2-3 = 0,826).Conclusion. Layered dermatolipectomy with autodermoplasty and endoscopic decompression fasciotomy is an effective method for the treatment of persistent refractory venous trophic ulcers.

AbstractThere is no consensus on the optimal timing of laparoscopic cholecystectomy (LC) after percutaneous transhepatic gallbladder drainage (PTGBD) for patients with acute cholecystitis (AC). We retrospectively evaluated patients who underwent LC after PTGBD between 1 February 2016 and 1 February 2020. We divided patients into three groups according to the interval time between PTGBD and LC as follows: Group I (within 1 week), (Group II, 1 week to 1 month), and Group III (> 1 month) and analyzed patients’ perioperative outcomes. We enrolled 100 patients in this study (Group I, n = 22; Group II, n = 30; Group III, n = 48). We found no significant difference between the groups regarding patients’ baseline characteristics and no significant difference regarding operation time and estimated blood loss (p = 0.69, p = 0.26, respectively). The incidence of conversion to open cholecystectomy was similar in the three groups (p = 0.37), and we found no significant difference regarding postoperative complications (p = 0.987). Group I had shorter total hospital stays and medical costs (p = 0.005, p < 0.001, respectively) vs Group II and Group III. Early LC within 1 week after PTGBD is safe and effective, with comparable intraoperative outcomes, postoperative complications, and conversion rates to open cholecystectomy. Furthermore, early LC could decrease postoperative length of hospital stay and medical costs.

Abstract. Twenty-four patients with non-secreting tumours of the hypothalamic-pituitary region, diagnosed by radiographic procedures and confirmed at surgery, were examined before and after the surgical treatment to establish a correlation between Prl responsiveness to dynamic tests and the location of pathological tissue. Three groups of patients were identified. In 10 patients with an intrasellar tumour (group I), Prl had a positive response to TRH, metoclopramide (MCP), and nomifensine (NOM), both pre- and postoperatively. In 4 patients with tumours located entirely in the hypothalamus (group II), Prl responded to TRH, but remained unresponsive to MCP and NOM. Only a partial normalization of the Prl responses was obtained after surgery. Finally, 10 patients had an intra- and extrasellar tumour (group III). In 8 of them Prl responded to TRH, but the increment was lesser than that observed in hypothalmic tumours. Prl did not respond to MCP and NOM. After surgery, Prl responsiveness reappeared in some patients (6 after TRH, 4 after MCP, 3 after NOM). In 2 patients with extensive pituitary damage, Prl did not respond to all dynamic tests pre- or postoperatively. In conclusion, Prl dynamic tests are a reliable tool for studying the altered control of Prl secretion in these patients, since plasma Prl stems from only normal lactotropes surrounding the tumoural tissue. The location of the tumour has a key role in influencing the pattern of Prl response to direct and indirect dynamic tests.

Background In the Ponseti technique, the residual equinus deformity is corrected with percutaneous tenotomy. This experimental study aimed to compare the safety and effectiveness of a large-gauge needle, a corneal knife, and a No. 11 blade in percutaneous achillotomy performed in rats. Methods Ninety Achilles tendons of 45 Sprague-Dawley rats were analyzed, following division into three study groups. In the study, group I (needle), group II (corneal knife), and group III (No. 11 blade) were compared on the basis of bleeding, incision length, requirement for primary suture, range of motion, and resulting neurovascular injury at day 0. Moreover, the groups were compared in terms of range of motion, macroscopic and microscopic adhesions, and tenocyte morphology at days 21 and 42 postoperatively. Results On day 0, one suture was required in group III, whereas in groups I and II, no sutures were required. Postoperative bleeding was greater in group III and similar in groups I and II. Neurovascular injury was not observed in any of the groups. Three incomplete tenotomies were observed in group III and one incomplete tenotomy was observed in group II. Importantly, all tenotomies were complete in group I. In all groups, the range of motion was similar. The macroscopic adhesion score revealed high adhesion in group III (P = .009). According to Tang's criteria, microscopic adhesion was significantly higher on day 21 in group III compared with the other groups (P &lt;0.001). No significant differences were observed in tenocyte morphology based on the Bonar criteria (P = .850). Conclusions In the results obtained from this animal study, we observed less bleeding, less adhesion, and less incomplete tenotomy in the large-gauge needle and corneal knife groups compared with the No. 11 blade group during the percutaneous Achilles tenotomy performed in rats.
