A Case of Bilateral Cryptococcal Olecranon Bursitis.

Non-septic olecranon bursitis (NSOB) is the inflammation of the olecranon bursa, which is usually self-limiting with aseptic clinical manifestations. NSOB can be idiopathic or secondary to repetitive trauma or rheumatological conditions. Septic olecranon bursitis (SOB) is usually caused by bacterial skin colonisers, such as staphylococci and streptococci, and patients tend to present with systemic symptoms requiring medical and/or surgical interventions. Herein we present a case of disseminated cryptococcal infection stemming from bilateral septic olecranon bursitis in a previously healthy immunocompetent 24-year-old female. Fluid cultures were positive for Cryptococcus neoformans. Patient underwent bilateral olecranon bursectomy, washouts and debridement. Moreover, the patient was started on long-term intravenous amphotericin B and later switched to oral flucytosine and fluconazole with good effect. Patient had good clinical outcomes at one-year follow-up.  SOB secondary to unusual pathogens, such as Cryptococcus neoformans, is a rare occurrence, and tends to affect immunocompromised individuals. The clinical course of such infections has shown to be subtle and insidious, which in turn hinders the diagnosis and leads to inappropriate treatment administration. Early follow-up and consideration of these organisms, together with appropriate discussion with microbiologists and/or infectious disease teams is crucial to reduce long-term morbidity and mortality.

Minimum 5-Year Clinical and Return-to-Sport Outcomes After Primary Arthroscopic Scapulothoracic Bursectomy and Partial Scapulectomy for Snapping Scapula Syndrome.

BACKGROUND: Snapping scapula syndrome (SSS) is a rare condition that is oftentimes debilitating. For patients whose symptoms are resistant to nonoperative treatment, arthroscopic surgery may offer relief. Because of the rarity of SSS, reports of clinical outcomes after arthroscopic SSS surgery are primarily limited to small case series and short-term follow-up studies. PURPOSE: To report minimum 5-year clinical and sport-specific outcomes after arthroscopic bursectomy and partial scapulectomy for SSS and to identify demographic and clinical factors at baseline associated with clinical outcomes at minimum 5-year follow-up. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients who underwent arthroscopic bursectomy and partial scapulectomy for SSS between October 2005 and February 2016 with a minimum of 5 years of postoperative follow-up were enrolled in this single-center study. Clinical outcome scores, including the 12-Item Short Form Health Survey (SF-12), American Shoulder and Elbow Surgeons (ASES) Shoulder Score, shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, Single Assessment Numeric Evaluation (SANE), and visual analog scale (VAS) score for pain, were collected at a minimum 5-year follow-up. Additionally, it was determined which patients reached the minimal clinically important difference. Bivariate analysis was used to determine whether baseline demographic and clinical factors had any association with the outcome scores. RESULTS: Of 81 patients eligible for inclusion in the study, follow-up was obtained for 66 patients (age 33.6 ± 13.3 years; 31 female). At a mean follow-up of 8.9 ± 2.5 years (range, 5.0-15.4 years), all of the outcome scores significantly improved compared with baseline. These included the ASES (from 56.7 ± 14.5 at baseline to 87.2 ± 13.9 at follow-up; P < .001), QuickDASH (from 38.7 ± 17.6 to 13.1 ± 14.6; P < .001), SANE (from 52.4 ± 21.2 to 82.7 ± 19.9; P < .001), SF-12 Physical Component Summary (from 39.7 ± 8.3 to 50.3 ± 8.2; P < .001), SF-12 Mental Component Summary (from 48.2 ± 11.7 to 52.0 ± 9.0; P = 0.014) and VAS pain (from 5.2 ± 2.1 to 1.4 ± 2.0; P < .001). The minimal clinically important difference in the ASES score was reached by 77.6% of the patients. Median postoperative satisfaction was 8 out of 10. It was found that 90.5% of the patients returned to sport, with 73.8% of the patients able to return to their preinjury level. At the time of final follow-up, 8 (12.1%) patients had undergone revision surgery for recurrent SSS symptoms. Older age at surgery (P = .044), lower preoperative SF-12 Mental Component Summary score (P = .008), lower preoperative ASES score (P = .019), and increased preoperative VAS pain score (P = .016) were significantly associated with not achieving a Patient Acceptable Symptom State on the ASES score. CONCLUSION: Patients undergoing arthroscopic bursectomy and partial scapulectomy for SSS experienced clinically significant improvements in functional scores, pain, and quality of life, which were sustained at a minimum of 5 years and a mean follow-up of 8.9 years postoperatively. Higher patient age, inferior mental health status, increased shoulder pain, and lower ASES scores at baseline were significantly associated with worse postoperative outcomes.

Clinical Outcomes Following Open Olecranon Bursa Excision for Septic and Aseptic Olecranon Bursitis: An Observational Study.

Background and objective Olecranon bursitis (aseptic or septic) is caused by inflammation in the bursal tissue. While it is typically managed with conservative measures, refractory cases may indicate surgical intervention. There is currently limited research about outcomes following bursal excision for both septic and aseptic etiologies. In light of this, the purpose of this study was to determine if patients experienced improvement following surgical olecranon bursa excision and to compare outcomes between septic and aseptic forms. Materials and methods A retrospective review was performed involving patients who underwent olecranon bursa excision from 2014 to 2021. Demographic data, patient characteristics, surgical data, and outcome-related data were collected from the medical records. Patients were classified into subgroups based on the type of olecranon bursitis (septic or aseptic). Preoperative and one-year postoperative 12-item short-form survey (SF-12) results and range of motion (ROM) outcomes were evaluated for the entire cohort as well as the subgroups. Results We included 61 patients in our study and found significant improvement in the Physical Component Scale 12 (PCS-12) score for all patients (42.0 vs. 45.5, p=0.010) following surgery. However, based on subgroup analysis, the aseptic group improved in PCS-12 following surgery (41.5 vs. 46.8, p<0.001), but the septic group did not (43.6 vs. 40.5, p=0.277). No improvements were found in the Mental Component Scale 12 (MCS-12) scores following surgery in either group. Eighteen of the 61 patients experienced postoperative complications (29.5%), but only 6.5% required a second surgical procedure. Specifically, 14 of the 18 complications occurred in the aseptic group while two septic and two aseptic patients required additional surgeries. Elbow ROM did not change significantly after surgery but more patients were found to have full ROM postoperatively (83.0% to 91.8%, p=0.228). Conclusion Our findings suggest that patients with refractory olecranon bursitis, particularly if aseptic, tend to gain significant physical health benefits from open bursectomy.

Excision of trochanteric bursa during total hip replacement: Does it reduce the incidence of post-operative trochanteric bursitis?

BACKGROUND: Trochanteric bursitis is a common complication following total hip replacement (THR), and it is associated with high level of disability and poor quality of life. Excision of the trochanteric bursa prophylactically during THR could reduce the occurrence of post-operative trochanteric bursitis. AIM: To evaluate whether synchronous trochanteric bursectomy at the time of THR affects the incidence of post-operative trochanteric bursitis. METHODS: This retrospective cohort study was conducted in the secondary care setting at a large district general hospital. Between January 2010 and December 2020, 954 patients underwent elective primary THR by two contemporary arthroplasty surgeons, one excising the bursa and the other not (at the time of THR). All patients received the same post-operative rehabilitation and were followed up for 1 year. We reviewed all cases of trochanteric bursitis over this 11-year period to determine the incidence of post-THR bursitis. Two proportion Z-test was used to compare incidences of trochanteric bursitis between groups. RESULTS: 554 patients underwent synchronous trochanteric bursectomy at the time of THR whereas 400 patients did not. A total of 5 patients (incidence 0.5%) developed trochanteric bursitis following THR; 4 of whom had undergone bursectomy as part of their surgical approach, 1 who had not. There was no statistically significant difference between the two groups (Z value 1.00, 95%CI: -0.4% to 1.3%, P = 0.32). There were also 8 other patients who had both trochanteric bursitis and hip osteoarthritis prior to their THR; all of whom were treated with THR and synchronous trochanteric bursectomy, and 7 had resolution of their lateral buttock pains but 1 did not. CONCLUSION: Synchronous trochanteric bursectomy during THR does not materially affect the incidence of post-operative bursitis. However, it is successful at treating patients with known trochanteric bursitis and osteoarthritis requiring THR.

Septic retrocalcaneal bursitis in a young soccer player treated with hindfoot endoscopic bursectomy: a case report.

Septic retrocalcaneal bursitis (RB) is extremely rare with no reports on surgical treatment. Here, we describe a rare case of septic RB in a 14-year-old male soccer player who was treated with hindfoot endoscopic bursectomy. A 14-year-old male soccer player complained of right heel pain without trauma histories when he was playing a soccer. Based on physical examination, radiological findings and laboratory results, we diagnosed the patient with septic RB and started to treat with conservative treatment including a non-weightbearing splint and intravenous antibiotics therapy. However, his symptoms and laboratory results did not improve at 4 days after starting intravenous antibiotics therapy, and so we applied hindfoot endoscopic bursectomy for him. At 4 weeks after the surgery, he could return to the original sport at preinjury level without symptoms and complications. Septic RB in a 14-year-old male soccer player was successfully treated with hindfoot endoscopic bursectomy.

Good functional outcomes after endoscopic treatment for greater trochanteric pain syndrome.

PURPOSE: Greater trochanteric pain syndrome (GTPS) is a term covering different conditions generating lateral hip pain. Recalcitrant cases may require surgery but there are only a few studies evaluating endoscopic treatment. This study aimed to evaluate the outcome of endoscopically treated GTPS at minimum two years postoperatively using patient-reported outcome measures (PROMs), and to assess the complication rate associated with endoscopic surgery. METHODS: A total of 33 patients, mean age 43.2 years, 88% women, with a mean symptom duration of 3.5 years, were included in the study. A total of 36 operated hips were included. Pre- and at minimum two years postoperatively the patients completed questionnaires consisting of the International Hip Outcome Tool (iHOT-12) and the Hip Sports Activity scale (HSAS), the Visual analogue scale for overall hip function (VAS-OHF), the Copenhagen Hip and Groin Outcome Score (HAGOS), the EuroQoL-5 Dimension Questionnaire (EQ-5D) and the EQ-VAS. Complications were assessed using the Clavien-Dindo classification. RESULTS: Median follow-up time was 24.5 months postoperatively. Statistically significant improvements were seen for the following PROMs (p < 0.05); iHOT-12 (36.3 vs 54.0), HAGOS different subscores (40.8 vs 59.0, 46.5 vs 62.6, 29.9 vs 53.1, 33.5 vs 51.4, 20.7 vs 41.4, 23.4 vs 43.3), EQ-VAS (55.9 vs 63.3) and EQ-5D (0.392 vs 0.648). VAS-OHF and HSAS did not reach significance. There was a 71% satisfaction rate with the surgery. Three Clavien-Dindo grade 1 and one grade 2 complications were registered postoperatively, with 41% of patients achieving PASS for iHOT-12 at two years follow-up. CONCLUSION: Endoscopic surgery for greater trochanteric pain syndrome improved patient-reported outcomes and the procedure was associated with low risk of complications. LEVEL OF EVIDENCE: Level IV.

Surgical Management of Scapulothoracic Bursitis in a Patient with Systemic Lupus Erythematosus: A Case Report.

Scapulothoracic bursitis involves inflammation of the scapulothoracic bursa caused by overuse of the shoulder or traumatic injury. Conservative management is recommended initially, and a surgical approach, such as bursectomy or scapular angle resection, is indicated later. Scapulothoracic bursitis in a patient with systemic lupus erythematosus (SLE) has been rarely reported in the literature. A 34-year-old woman was hospitalized in our hospital for a palpable mass on the right side of her back. She had a history of SLE, which was diagnosed and treated with medication 13 years prior. Chest magnetic resonance imaging (MRI) revealed fluid collection measuring 6.0 cm × 6.0 cm × 2.0 cm between the rib cage and subscapularis muscle. Histopathological examination identified the mass as bursitis with cystic degeneration. Surgical excision was performed at the infrascapular area. About 11 months later, the mass recurred in the same area. Surgical excision was again performed in the same way as before, and the same diagnosis was confirmed. Every 6 months, ultrasound examination is being conducted to assess for recurrence. The patient has not had any further complications or a relapse for the last 3 years. Prompt bursectomy can be a definitive and long-lasting treatment option for scapulothoracic bursitis accompanied by SLE.

Outcomes after arthroscopic scapulothoracic bursectomy for the treatment of symptomatic snapping scapula syndrome.

Background: The purpose of our study was to examine the clinical outcomes after arthroscopic scapulothoracic bursectomy for the treatment of scapulothoracic bursitis at a minimum of 2-year follow-up. Methods: Twenty patients who underwent arthroscopic scapulothoracic bursectomy for the treatment of symptomatic snapping scapula syndrome were identified from a single surgeon's database. Patients were indicated for surgery if their symptoms persisted for more than 6 months and if they failed nonoperative treatment. Acquired data included patient demographics, shoulder range of motion, American Shoulder and Elbow Surgeon score, visual analog scale scores for pain, and the following Patient-Reported Outcomes Measurement Information System scores: Upper Extremity Computer Adaptive Test Version 2.0, pain intensity, and pain interference scores. Patient satisfaction and subjective shoulder value were also recorded out of 100. Fisher's test and unpaired t tests were performed for statistical analysis, and P values <.05 were considered significant. Results: A total of 20 patients (24 scapulae) were included in our study, with an average follow-up period of 44 (range: 27-91) months. The mean postoperative Patient-Reported Outcomes Measurement Information System scores for Upper Extremity Computer Adaptive Test Version 2.0, pain interference, and pain intensity were 44.2 ± 10.7, 50.9 ± 9.5, and 42.1 ± 9.5, respectively. The mean postoperative American Shoulder and Elbow Surgeon score was 79.0 ± 21.5, and the mean subjective shoulder value was 82.7 ± 12.9. Visual analog scale pain levels showed a significant decrease from 4.95 ± 2.26 preoperatively to 2.27 ± 2.7 (P < .05) postoperatively. There was no significant difference in shoulder range of motion after surgery. The mean patient satisfaction was 72.9, with 65% (13/20) of patients reporting satisfaction levels ≥ 80%. Two patients did not report the resolution of their symptoms and required revision surgery. Conclusion: Arthroscopic treatment of scapulothoracic bursitis is a safe, reliable technique that is effective in providing symptomatic relief with a low rate of recurrence, with most patients reporting a significant reduction in periscapular pain.

Case report: Primary chronic calcaneal bursitis treated with subtotal bursectomy in a cat.

A 6-year-old, female spayed Bengal cat with a bodyweight of 6.4 kg was presented with swelling of the bilateral calcaneal region and weight-bearing hindlimb lameness with a 4-month history of unsuccessful conservative therapy. On orthopedic examination, a cyst-like mass around the calcaneal tendon was palpated. Palpating the mass and flexing the tarsal joint triggered pain. Through ultrasonography and magnetic resonance imaging, an inflamed or fluid-accumulated lesion was suspected around the calcaneal tendon, but there was no evidence of calcaneal tendonitis. Swollen calcaneal bursae were removed surgically. Histopathologic examination revealed fibrosis and an edematous feature. The cat was diagnosed with bilateral chronic primary calcaneal bursitis based on history, clinical signs, and diagnostic results. Hence, subtotal bursectomy was performed. At 4 weeks postoperatively, the cat had no pain around the tarsal joints and was ambulating normally. Radiographic and ultrasonographic exams revealed no recurrence of swelling or inflammation in the calcaneal region. Thirteen-month follow-up confirmed acceptable function and no relapse of clinical signs. The inflammation of calcaneal bursa alone can be the primary cause of hindlimb lameness in cats. A cat with hindlimb lameness and swelling on the calcaneal region should be assessed with the possibility of primary calcaneal bursitis. Subtotal calcaneal bursectomy can be considered as an effective treatment for primary chronic bursitis.

The Importance of the Bursa of Fabricius, B Cells and T Cells for the Pathogenesis of Marek's Disease: A Review.

The importance of the bursa of Fabricius (BF) for the pathogenesis of Marek's disease (MD) has been studied since the late 1960's. In this review, the results of these studies are analyzed in the context of the developing knowledge of the immune system of chickens and the pathogenesis of MD from 1968 to 2022. Based on the available techniques to interfere with the development of the BF, three distinct periods are identified and discussed. During the initial period between 1968 and 1977, the use of neonatal bursectomy, chemical methods and irradiation were the main tools to interfere with the B lymphocyte development. The application of these techniques resulted in contradictory results from no effects to an increase or decrease in MD incidence. Starting in the late 1970's, the use of bursectomy in 18-day-old embryos led to the development of the "Cornell model" for the pathogenesis of MD, in which the infection of B lymphocytes is an important first step in MD virus (MDV) replication causing the activation of thymus-derived lymphocytes (T cells). Following this model, these activated T cells, but not resting T cells, are susceptible to MDV infection and subsequent transformation. Finally, B-cell knockout chickens lacking the J gene segment of the IgY heavy chain gene were used to further define the role of the BF in the pathogenesis of MD.

[Evidence-Based Treatment and Differential Diagnoses of Olecranon Bursitis]. / Evidenz-basierte Behandlung und Differenzialdiagnostik der Bursitis olecrani.

Evidence-Based Treatment and Differential Diagnoses of Olecranon Bursitis Abstract. Bursitis olecrani is a common clinical diagnosis that can have systemic, infectious and traumatic causes. In this article we want to present the diagnostics, possible differential diagnoses, complications and the current therapy recommendations as a practical guide.

Arthroscopic treatment of type I and II greater trochanteric pain syndrome.

The goal of this study was to describe and evaluate endoscopic bursectomy combined with fascia lata lengthening in the treatment of type I and II greater trochanteric pain syndrome recalcitrant to conservative management. This was a retrospective study of 20 patients (7 type I, 13 type II) reviewed with a minimum follow-up of 2 years. The mean follow-up was 44±11 [26-65] months. While significant improvements in pain, mHHS and NAHS were found, 80% of patients still had hip pain graded at≥3 on VAS. The satisfaction rate was 7/10±2 [3-10]. Snapping in the hip had been eliminated in 100% of cases. No complications were observed. This is a minimally invasive surgery that is feasible in patients who have failed an optimal course of conservative treatment. But patients must be informed that pain might not be completely eliminated by this procedure. LEVEL OF EVIDENCE: IV; retrospective, case series.

B cells do not play a role in vaccine-mediated immunity against Marek's disease.

BACKGROUND: Marek's disease virus (MDV), a highly oncogenic α-herpesvirus, is the etiological agent of Marek's disease (MD) in chickens. The antiviral activity of vaccine-induced immunity against MD reduces the level of early cytolytic infection, production of cell-free virions in the feather follicle epithelial cells (FFE), and lymphoma formation. Despite the success of several vaccines that have greatly reduced the economic losses from MD, the mechanism of vaccine-induced immunity is poorly understood. METHODS: To provide insight into possible role of B cells in vaccine-mediated protection, we bursectomized birds on day of hatch and vaccinated them eight days later. The birds were challenged 10 days post vaccination with or without receiving adoptive lymphocytes from age-matched control birds prior to inoculation. The study also included vaccinated/challenged and non-vaccinated challenged intact birds. Flowcytometric analysis of PBMN cells were conducted twice post bursectomy to confirm B cell depletion and assess the effect of surgery on T cell population. Immunohistochemical analysis and viral genome copy number assessment in the skin samples at termination was performed to measure the replication rate of MDV in the FFE of the skin tissues of the challenged birds. RESULTS: The non-vaccinated/challenged birds developed typical clinical signs of MD while the vaccinated/challenged and bursectomized, vaccinated/challenged groups with or without adoptive lymphocyte transfer, were fully protected with no sign of transient paralysis, weight loss, or T cell lymphomas. Immunohistochemical analysis and viral genome copy number evaluation in the skin samples revealed that unlike the vaccinated/challenged birds a significant number of virus particles were produced in the FFE of the non-vaccinated/challenged birds at termination. In the bursectomized, vaccinated/challenged groups, only a few replicating virions were detected in the skin of birds that received adoptive lymphocytes prior to challenge. CONCLUSIONS: The study shows that B cells do not play a critical role in MD vaccine-mediated immunity.

Open Versus Arthroscopic Surgical Management for Recalcitrant Trochanteric Bursitis: A Systematic Review.

Background: While excision of the trochanteric bursae to treat lateral hip pain has increased in popularity, no comparison exists between the surgical outcomes and complications of the open and arthroscopic techniques involving trochanteric bursectomy. The purpose of this study was to determine the efficacies and complication rates of arthroscopic and open techniques for procedures involving trochanteric bursectomy. Methods: The terms "trochanteric," "bursectomy," "arthroscopic," "open," "outcomes," and "hip" were searched in five electronic databases. Fifteen studies from 120 initial results were included. Patient-reported outcomes (PRO), pain, satisfaction, and complications were included for analysis. Results: Five hundred-two hips in 474 total patients (77.7% female) were included in this study. The average age was 54. The fourteen distinct PRO scores that were reported by the included studies improved significantly from baseline to final mean follow-up (12-70.8 months for open; 12-42 months for arthroscopic) for both approaches, demonstrating statistically significant patient benefit in a variety of hip arthroscopy settings (P > 0.05). The complication rates of all procedures ranged from 0%-33% and failure to improve pain ranged from 0%-8%. Patient satisfaction with surgery was high at 95% and 82% reported a willingness to undergo the same surgery again. No significant mean differences were found between the open and arthroscopic techniques. Conclusion: The open and arthroscopic approaches for trochanteric bursectomy are both safe and effective procedures in treating refractory lateral hip pain. No significant differences in PROs, pain, total complications, severity of complications, and total failures were seen between technique outcomes.Level of Evidence: IV.

Clinical Management of Olecranon Bursitis: A Review.

Olecranon bursitis is a disease characterized by inflammation of the olecranon bursa, most often due to microtrauma. Although it is a common condition, there is a lack of evidence-based recommendations for the management of nonseptic olecranon bursitis. The condition is often self-limited and resolves with conservative methods such as rest, ice, compression, orthosis wear, and nonsteroidal anti-inflammatory medications. Older studies have shown resolution of symptoms with intrabursal corticosteroid injections and surgical bursectomy. More recent literature has demonstrated adverse effects of intrabursal injections and surgery compared with noninvasive management for initial treatment of nonseptic olecranon bursitis. In order to better tailor decision-making, it is important that hand surgeons understand the comparative efficacies of each option for management of nonseptic olecranon bursitis.

Saline Load Test and Quilting Sutures to Treat Intractable Lateral Malleolar Bursitis.

The purpose of this study was to evaluate the clinical outcomes of patients with intractable lateral malleolar bursitis who were treated using the intraoperative saline load test to find communication between the bursal sac and the ankle joint and the quilting sutures after bursectomy to reduce the dead space. We reviewed a total of 28 patients who had been treated with quilting sutures after bursectomy between April 2014 and June 2017. When there was capsular opening detected with the saline load test, it was closed with sutures or augmented with periosteum. On the final follow-up office visit, the lateral malleolus was examined for the recurrence of bursitis. Patient medical records were reviewed for postoperative wound dehiscence, skin necrosis, infections, and nerve symptoms. The saline load test was positive in 11 (42%) cases. The mean foot function index improved from 25.94 ± 20.46 to 11.73 ± 5.27 (p = .003). Fourteen (54%) patients were very satisfied with the results, 9 (35%) were satisfied, 2 (8%) rated their satisfaction as fair, and 1 (4%) was dissatisfied. No cases required skin graft or flap surgery. Intractable lateral malleolar bursitis was successfully treated using the saline load test and quilting sutures after bursectomy. Closure of the capsular opening prevented fluid drainage around the wound. Quilting sutures after bursectomy reduced dead space underneath the wound to prevent fluid accumulation and promoted healing of the skin on the underlying soft tissue.

Lack of Oncological Benefit from Bursectomy in Radical Gastrectomy: A Systematic Review.

BACKGROUND: Resection of the omental bursa has been suggested to reduce peritoneal recurrence and facilitate a complete oncological resection during a gastrectomy. The addition of this procedure increases technical complexity and prolongs the procedure. Published data regarding the oncological benefit of this procedure are conflicting. We hypothesized that a bursectomy during a radical gastrectomy does not improve overall survival. METHODS: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guideline, a comprehensive literature search of 3 electronic databases (PubMed, Scopus, and Embase) was conducted to identify the clinical studies that compared bursectomy with no-bursectomy in radical gastrectomy for gastric adenocarcinoma. Qualitative and quantitative data synthesis was performed using RevMan software. A random-/fixed-effect modeling was used depending upon the heterogeneity. Bias and quality assessment tools were applied. The study was registered with the International Prospective Register of Systematic Reviews (PROSPERO) (CRD42019116556). RESULTS: Of 8 studies assessing the role of bursectomy in gastric adenocarcinoma, 6 (75%) were included - of which 2 (33%) are randomized controlled trials. Of 2,904 patients, 1,273 (%) underwent a bursectomy. There was no statistically significant difference in either overall survival (hazard ratio [HR] = 0.89, 95% CI 0.75-1.06, I2 = 14%) or disease recurrence (HR = 1.01, 95% CI 0.84-1.20, I2 = 22%) in the bursectomy group compared to the no-bursectomy group. CONCLUSION: There is no additional oncological benefit of adding bursectomy to radical gastrectomy in all patients with gastric adenocarcinoma.

Subacromial bursal preservation can enhance rotator cuff tendon regeneration: a comparative rat supraspinatus tendon defect model study.

BACKGROUND: The role of subacromial bursa in rotator cuff surgery is unknown. This study aimed to assess the subacromial bursa's role in the healing of supraspinatus tendon injury in a rat model. METHODS: Twenty-three male Sprague-Dawley rats (9 weeks old; weight, approximately 296 g) were used in this study. Three rats used as biomechanical study controls were killed at 12 weeks of age. A supraspinatus tendon defect was made bilaterally in 20 rats, whereas an additional subacromial bursa sectioning was performed on the left side. Six rats were killed for biomechanical testing and 4 were killed for histologic observation at 3 and 9 weeks, respectively. RESULTS: The regenerated tendon in the bursal preservation group showed significantly superior biomechanical properties in maximum load to failure at 3 and 9 weeks and stiffness at 9 weeks after surgery compared with the bursal removal group. The modified Bonar scale scores showed better regenerated supraspinatus tendons in the bursal preservation group. CONCLUSION: The present study found that the subacromial bursa plays an important role in rotator cuff regeneration in this rat supraspinatus injury model. Extensive bursectomy of the subacromial bursa may not be recommended in rotator cuff repair surgery, though future in vivo human studies are needed to confirm these observations.

Factors associated with revision surgery for olecranon bursitis after bursectomy.

BACKGROUND: The primary aim of our study was to identify the factors associated with revision surgery after bursal excision in patients with olecranon bursitis. The secondary aims were to describe the revision rate after bursectomy and to assess which factors are associated with flap surgery after bursectomy and describe the most common complications after bursectomy of the olecranon bursa. METHODS: We included 191 adult patients with olecranon bursitis who underwent olecranon bursa excision between January 2002 and October 2018. Patients who were pregnant, patients with incomplete records of the primary surgical procedure, and patients who underwent bursectomy during elbow arthroplasty were excluded. After manual chart review, we found that 22 patients had undergone revision surgery. Bivariate analysis was performed to assess the association between revision surgery and patient characteristics, comorbidities, and clinical characteristics. Additionally, we collected data regarding postoperative complications and intraoperative variables such as the use of drains, vacuum assisted closure therapy, and flap surgery. RESULTS: The overall revision rate in our cohort was 11.5% (22 of 191 patients). Bivariate analysis showed that patients who underwent revision surgery were more frequently women (P = .004), more often had a history of ipsilateral (P = .020) or contralateral (P = .012) olecranon bursitis, and more often received a diagnosis of rheumatoid arthritis (P = .001) or diabetes mellitus (P = .019). The most common complications were delayed wound healing (n = 8, 4.2%) and osteomyelitis (n = 8, 4.2%). Flap surgery was performed in 5 patients (2.6%). Bivariate analysis showed that patients with rheumatoid arthritis underwent flap surgery more frequently (P = .011). CONCLUSION: The revision rate after bursectomy for olecranon bursitis was 11.5% (22 of 191 patients). Patients with rheumatoid arthritis, diabetes mellitus, or a history of ipsilateral and contralateral olecranon bursitis and female patients underwent revision surgery after bursectomy for olecranon bursitis more frequently. In addition, patients with rheumatoid arthritis underwent flap surgery after bursectomy more frequently.
