Rupture Of The Bladder

Introduction. Еven though open bladder suturing is a traditional method of surgical treatment of intraperitoneal rupture of the bladder, laparoscopic bladder suturing is a prospective method for treating such injuries. Materials and methods. In N.V. Sklifosovsky Research Institute of Emergency Care during the period from January 2016 to April 2020, 22 patients with bladder injury were treated. 15 of them had an intraperitoneal rupture, 5 had an extraperitoneal rupture, and 2 had a bladder rupture. Among the affected men there were 15 (68%), women - 7 (32%), the average age of patients was 42 ± 18 years. The clinical picture was dominated by gross hematuria and pain in the lower abdomen. All patients underwent ultrasound examination (US) according to the FAST protocol, and cystography was performed in some patients. Results. 20 (91%) patients were operated and 2 (9%), with extraperitoneal rupture of the bladder, were drained by urethral catheters. Patients were divided by the method of surgical treatment into 2 groups. In the 1st group, 2 (10%) patients underwent laparoscopic suturing of the bladder with drainage of the bladder with a urethral catheter. 18 (90%) patients of the 2nd group underwent laparotomy with suturing of the bladder. Depending on the method of bladder drainage, patients were divided into the cystostomy group (group A) and the urethral catheter group (group B). Group A - 16 (73%) patients who underwent laparotomy, suturing a rupture or ruptures of the bladder, epicystostomy, drainage of the abdominal cavity and lower pelvis. Group B-4 (18%) patients after laparotomy, laparoscopy, as well as patients who underwent conservative therapy with the installation of an urethral catheter – 2 (9%). Discussion. In the world literature, there are few scientific articles on the laparoscopic method of treating bladder injury, and the presented works are based on a small sample of patients. But, despite this, the method seems to be a promising and effective method for treatment and can be used in patients with intraperitoneal rupture of the bladder with stable hemodynamics, without life-threatening concomitant injuries. Conclusion. Тhe use of open or laparoscopic suturing of the bladder without epicycostomy significantly reduces the hospital stay and allows to restore natural urination on average 7 days after surgery. Laparoscopic suturing of the bladder is an effective and alternative treatment for bladder rupture.

Rupture Of The Bladder

INTRODUCTION: In closed intraperitoneal bladder trauma, an alternative to laparotomy is laparoscopy. The rupture is closed with endoscopic sutures, and the bladder is drained with a urethral catheter. In the literature, the issue of the placement of a trocar cystostomy during laparoscopic treatment of patients with intraperitoneal bladder ruptures requiring prolonged drainage is insufficiently covered. PURPOSE OF THE STUDY: Determination of the optimal trocar cystostomy method during laparoscopic treatment of intraperitoneal bladder rupture. MATERIALS AND METHODS: Trocar cystostomy was performed in 8 patients with intraperitoneal bladder ruptures, among whom 7 had concomitant diseases of the prostate gland, and 1 had urethral stricture. Trocar cystostomy during laparoscopic surgery was performed in three different ways. Results. In the first method, the rupture of the bladder was initially sutured. Then, through the urethral catheter, the bladder was filled with saline. A trocar cystostomy was inserted through the suprapubic region. The second method consisted in the installation of a trocar cystostomy under the control of a laparoscope even before the suturing of the bladder rupture. In the third method proposed by us (patent No. 2592023), a Foley-type catheter with a balloon capacity of at least 200 ml was inserted into the abdominal cavity through the laparoscopic port. A catheter was inserted from the abdomen through an intraperitoneal rupture into the bladder. Inside the bladder, the catheter balloon was filled with saline. Then, through the suprapubic region, the anterior abdominal wall, the bladder and the inflated balloon of the catheter were pierced layer by layer with a trocar. Another catheter was inserted through the trocar into the bladder. After removal of the catheter with a ruptured balloon, the intraperitoneal rupture of the bladder was sutured. FINDINGS: According to the results of the study, the third method of inserting a trocar cystostomy turned out to be the most optimal and safe.

Abstract Background The aim of this study is to analyse the re-operation rate after surgical treatment of osteochondral lesions of the talus (OCLTs) in children and adolescents. Methods Between 2009 and 2019, 27 consecutive patients with a solitary OCLT (10 male, 17 female; mean age 16.9 ± 2.2 years; 8 idiopathic vs. 19 traumatic) received primary operative treatment (arthroscopy + bone marrow stimulation [BMS], n = 8; arthroscopy + retrograde drilling, n = 8; autologous chondrocyte implantation [ACI]/autologous bone grafting, n = 9; arthroscopy + BMS + retrograde drilling; n = 1; flake fixation, n = 1). Seventeen OCLTs were located at the medial and ten at the lateral talus. ‘Re-operation’ as the outcome measure was evaluated after a median follow-up of 42 months (range 6–117 months). Patients were further subdivided into groups A (re-operation, n = 7) and B (no re-operation, n = 20). Groups A and B were compared with respect to epidemiological, lesion- and therapy-related variables. Results Seven of 27 patients needed a re-operation (re-operation rate 25.9% after a median interval of 31 months [range 13–61 months]). The following operative techniques were initially used in these seven patients: arthroscopy + BMS n = 2, arthroscopy + retrograde drilling n = 4, ACI + autologous bone grafting n = 1. A comparison of group A with group B revealed different OCLT characteristics between both groups. The intraoperative findings according to the International Cartilage Repair Society (ICRS) classification revealed significantly more advanced cartilage damage in group B than in group A (p = 0.001). Conclusions We detected a re-operation rate of 25.9% after primary surgical OCLT treatment. Patients with re-operation had significantly lower ICRS classification stages compared to patients without re-operation.

Abstract PurposeThe present study aimed to explore the influence of ulnar bow on the surgical treatment of Bado type I missed Monteggia fracture in children.MethodsThis study is a retrospective review of 24 patients between November 2010 and March 2019. All patients were treated with open reduction of the radial head and ulnar opening wedge osteotomy without annular ligament reconstruction. The mean interval between injury onset and surgery was five months (range: 2–12 months). The average age of participants at the time of surgery was 6.4 years (range: 3–10 years). We evaluated the maximum ulnar bow (MUB) and MUB position (P-MUB) via radiography. The patients were divided into middle group (group A: 14 cases, MUB located at 40% to 60% of the distal ulna) and distal group (group B: 10 cases, MUB located at 20% to 40% from the distal end of the ulna) based on P-MUB. The mean period of follow-up was 37 months (range: 6–102 months).ResultsAt the last follow-up, all the children showed stable reduction of the radial head, and the flexion function of elbow joint improved after operation (P<0.05). Group A presented a larger the ratio of maximum ulnar bow(R-MUB) and angle of ulnar osteotomy(OA) than group B (P<0.05). There was statistically significant difference between group A and Group B in the P-MUB (P < 0.05). The osteotomy angle was positively correlated with the R-MUB (R2 =0.497,P=0.013), The osteotomy angle was positively correlated with the P-MUB (R2=0.731,P=0.000), The R-MUB is proportional to the P-MUB (R2 =0.597,P=0.002). The regression equation of P-MUB and osteotomy angle: Angle=7.064+33.227* P-MUB (R2=0.459, P =0.000).ConclusionWhen the ulnar bow is positioned at the middle ulna, a stable reduction of radial head need to be achieved through a larger angle in the ulnar osteotomy. If the position of maximum ulnar bow (P-MUB) is closer to the middle of the ulna or the ratio of maximum ulnar bow (R-MUB) is larger, the osteotomy angle is larger.

The purpose of this prospective double blind clinical study was to evaluate the analgesic efficacy of meloxicam with/without a buprenorphine patch for pain management after ovariohysterectomy in cats. Cats were randomly divided into two groups: ten cats were treated with meloxicam s.c. after ovariohysterectomy (Group A), and eight cats were treated with s.c. meloxicam and a 20 µg/h buprenorphine transdermal patch (Group B). For patch treatment, the cat’s hair was clipped on the left side in the thoracic area. Pain scores were assessed at 0.5, 1, 2, 4, 6, 8, 24 and 30 h post-ovariohysterectomy extubation. To evaluate postoperative pain, 4A-VET pain scale and visual analogue scale pain scores were used. In addition, blood was collected from all cats to determine the cortisol levels at –2 h and at 0.5, 4, 6 and 24 h after extubation. The 4A-VET scores for Group B were significantly lower at 1, 4, 6, 8, 24 and 30 h than the scores for Group A. The visual analogue scale pain scores for Group B were significantly lower at 4, 6, 24 and 30 h than the scores for Group A. Serum cortisol concentrations were not significantly different between Groups A and B at any of the measured intervals. There was a significant positive correlation between postoperative visual analogue scale and 4A-VET pain scores in both groups. Our results should be subject to careful interpretation as the study was limited by its small sample size and by observer subjectivity.

Background: Osteoarthritis (OA) is the most common form of arthritis accounting for about 30% of general physician visits. Objectives: To detect the effects of ultrasound therapy on patients with osteoarthritis of the knee joint.Methodology: It was a prospective non randomized clinical study, conducted in the Department of Physical Medicine and Rehabilitation, Bangabandhu Sheikh Mujib Medical University, Shahbagh, Dhaka during the periods of 1st March, 2012 to 31st August, 2012. Fifty four patients between 35-75 years of age without consideration of gender with a history of not less than three months knee pain with radiographic confirmation of primary osteoarthritis were selected purposefully. Then they were divided randomly in group A & group B. Group A received g NSAID [Aceclofenac 100mg B.D.-10 days]+Omeprazol (20mg B.D.-10days) + Therapeutic exercise + ADL and Group B received gUST+NSAID [Aceclofenac 100mg B.D.-10 days]+ Omeprazol (20mg B.D.-10days) + Therapeutic exercise + ADL. In both groups the patients were observed for six weeks. Outcome measured by VAS, ROM, 50 feet walking time and WOMAC index.Results: Mean ± SD of age in group A and group B were 52.33 ± 9.62 years and 52.29 ± 9.67 years respectively. Among the 27 patients in group A 9 (33.3%) were male and 18 (66.7%) were female. Among the 27 patients in group B 10 (37.0%) were male and 18 (63.0%) were female. Mean ± SD of VAS during pre treatment in group A and group B were 6.22 ± 1.60 and 7.15 ± 1.56 respectively. Mean ± SD of ROM during pre treatment in group A and group B were 117.33 ± 13.05 and 112.37 ± 19.01 respectively. Mean ± SD of time taken to walk 50 feet during pre treatment in group A and group B were 18.22 ± 2.39 and 18.81 ± 2.13 minutes respectively. Mean ± SD of WOMAC index in group A and group B were 60.85 ± 15.86 and 67.33 ± 16.33 minutes respectively. After treatment in both groups VAS, time taken to walk 50 feet and WOMAC index gradually decreased and ROM gradually increased.Conclusion: Although the study conducted with small sample size in a single centre in Dhaka city which may not be representative for the whole country it was found that there was statistically significant difference found in VAS, ROM, and time taken to walk 50 feet and WOMAC index between the groups.KYAMC Journal Vol. 7, No.-2, Jan 2017, Page 750-757

Background: Treatment of granular myringitis (GM) is diverse with no definitive management. Objective: The aim of the present study was to see the effectiveness of different interventions for treating granular myringitis. Methodology: This was a single centred, parallel, randomized control trial. This study was done at the Specialized ENT Hospital of SAHIC, Dhaka from July 2010 to June 2012. Patients presenting with granular myringitis of 18 years of age or more with both sexes were included. All patients were divided into two groups by simple random sampling method of which patients of group A were treated by surgical treatment and that of group B were treated by medical treatment. Medical treatment was given in the form of topical ear drops and surgical treatment was performed by surgical debridement of granulation tissue followed by chemical cauterization. Repeated follow up was performed up to 6 months in both groups of treated patients. The primary outcome was the resolution of granulation tissue. During follow-up the secondary outcome variables were recurrence, perforation of the TM and any other complications or complain from the patients. Results: A total number of 60 patients were studied of which 30 patients were treated medically and 30 patients were treated surgically. The cure rate was higher in surgical treatment (80%) than conservative (16.7%) (p=0.011). The recurrence rate (17.24%) is also less in surgical group compared to medical treatment group (77.27%) (p=0.001). Conclusion: Surgical treatment is a more successful treatment modality for granular myringitis. Journal of National Institute of Neurosciences Bangladesh, 2019;5(1): 64-68

Abstract OBJECTIVES Few experiences comparing paediatric and adult patients treated for pulmonary sequestration (PS) have been reported. Surgical treatment is considered the best choice, but the time of surgery is still controversial. We present our experience in this setting, comparing characteristics, histological results and outcome of paediatric and adult patients undergoing PS resection. METHODS Between 1998 and 2017, a total of 74 patients underwent lobectomy or sublobar resection for PS. Sixty patients were children (group A: ≤16 years old) and 14 were adults (group B: &gt;16 years old). Preoperative diagnosis was radiological. PS was intralobar (42 cases) and extralobar (32 cases). The operation was a muscle-sparing lateral thoracotomy or video-assisted thoracoscopic surgery. Preoperative characteristics, histological results and short-/long-term results of the 2 groups were retrospectively analysed and compared. RESULTS Thirty-seven percent of the patients in group A presented with respiratory symptoms and 79% in group B (P = 0.44). Most symptomatic patients were treated with a lobectomy. In group A, 2 patients (3%) had a malignant transformation of the lesion. Patients with a prenatal diagnosis treated after the age of 1 year became more symptomatic than those operated on before the age of 1 year (57% vs 23%; P = 0.08). No differences were found in postoperative complications. Long-term stable remission of respiratory symptoms was obtained in 91% of patients in group A and 100% in group B. Adulthood (P = 0.03) and the association with congenital cystic adenomatoid malformation (P = 0.03) were negative prognostic factors for the development of respiratory symptoms. CONCLUSIONS Surgical treatment of PS is safe and feasible. Despite the small number of patients included, study results indicated that an early operation during childhood may prevent the subsequent development of respiratory symptoms. Surgical treatment is also recommended to prevent the rare transformation into malignancy.

616 Background: Surgical treatment of metastatic colorectal cancer remains the only method that improves overall 5-year survival. This study aimed to compare the surgical outcome and survival benefit between synchronous and staged resection of liver metastases from colorectal cancer. Methods: Clinicopathologic data, treatments, and postoperative outcomes from 110 patients who underwent simultaneous (48 patients, group A) or staged (62 patients, group B) colorectal and hepatic resections at clinic of National cancer institute in period of 2008-2013 were reviewed. Results: Postoperative complications in patients with simultaneous resections (group A) were observed in 13 cases (27.1%), including 5, 1, 4, 2, 0, and 1 of grades I, II, IIIa, IIIb, IV, and V, respectively. Similar results have been reported in group B after staged resections, where overall postoperative complications registered in 16 patients (25.8 %), including 4, 3, 6, 3, 0 of grades I, II, IIIa, IIIb, and IV respectively. Overall level of post-operative complications in the groups A and B after surgical stages finishing did not differ statistically (p=0.96). Shorter operative intervention duration was registered in the group A – (311±10.1) min, whereas in the group B it was (496.6±16.2) min (р<0.001). Patients after staged resection stayed in clinic for a longer time – 23.9±0.8 bed-days, when simultaneous resections provided with shorter recovery terms in post-operative period – 9.8±0.5 bed-days (p<0.001). Overall 3-year survival in the group of patients with simultaneous resections (group А) was 42 % and in the group B 55 % (р=0.22). Conclusions: Analysis of our research indicated necessity of the development of differentiated approach in management of synchronous colorectal liver metastatic cancer. Simultaneous resections of colorectal cancer primary lesions and hepatic metastases were safe and could serve as a primary option for selected patients. Subsequent research should be directed towards study of prognosis factors and criteria for patients’ selection for surgical treatment groups, assessment of economic effect, and patients life quality.

This study compared surgical and non-surgical treatment of 46 calcaneal fractures in children aged 3-17 years. Patients were divided into: Group A ranging 3-14 years and Group B 15-17 years, and classified according to surgical or non-surgical treatment. Mean follow-up was 22.8 years. Extra-articular fractures were treated non-surgically and all results were satisfactory. Results of articular fractures in Group A were satisfactory regardless of the type of treatment. Articular fractures surgically treated in group B were satisfactory, and those non-surgically treated were mainly poor. Extra-articular fractures can be treated non-surgically. Articular fractures in skeletally immature children can be treated non-surgically; conversely, those in children with skeletal maturity must be treated surgically.

Mosaic Aneuploidy

Mosaicism, known as partial aneuploidies, mostly originates from mitotic errors during the post-zygotic stage; it consists of different cell lineages within a human embryo. The incidence of mosaicism has not been shown to correlate with maternal age, and its correlation with individual chromosome characteristics has not been well investigated. In this study, the results of preimplantation genetic testing for aneuploidy (PGT-A) derived from 4,036 blastocysts (930 IVF couples) were collected from 2015 to 2017. Via next-generation sequencing for comprehensive chromosome screening, embryo ploidy was identified as aneuploid, mosaic, and euploid. Total mosaicism was classified into two categories: “mosaic euploid/aneuploidy” (with mosaic aneuploidy between 20 and 80%) and “mosaic and aneuploidy” (a uniformly abnormal embryo superimposed with mosaic aneuploidies). Frequency of mosaicism was analyzed according to the function of chromosomal lengths, which divides involved chromosomes into three groups: group A (156–249 Mb), group B (102–145 Mb), and group C (51–90 Mb). The results show that the aneuploidy was more frequent in group C than in group A and group B (A: 23.7%, B: 35.1, 41.2%, p &lt; 0.0001), while the mosaicism was more frequent in group A and group B than in group C [(Mosaic euploid/aneuploid) A: 14.6%, B: 12.4%, C: 9.9%, p &lt; 0.0001; (mosaic and aneuploid) A: 21.3%, B: 22.9%, C: 18.9%, p &lt; 0.0001; (Total mosaicism) A: 35.9%, B: 35.3%, C: 28.8%, p &lt; 0.0001]. The significantly higher frequency of aneuploidy was on the shorter chromosome (&lt; 90 Mb), and that of mosaicism was on the longer chromosomes (&gt; 100 Mb). The length association did not reach significance in the patients with advanced age (≥ 36 years), and of the chromosome-specific mosaicism rate, the highest prevalence was on chromosome 14 (5.8%), 1 (5.7%), and 9 (5.6%). Although the length association was observed via group comparison, there may be affecting mechanisms other than chromosomes length. Eventually, twenty patients with mosaic embryo cryotransfers resulted in six live births. No significant correlation was observed between the transfer outcomes and chromosome length; however, the analysis was limited by small sample size.
