UNASSIGNED: Retroperitoneal leiomyomas are rare benign smooth muscle tumours. Diagnosing these tumours is often challenging due to their unique growth site and nonspecific clinical manifestations. There are a few reports of leiomyomas with intratumoral bleeding.
UNASSIGNED: A patient with a giant retroperitoneal leiomyoma presented with multiple-organ dysfunction syndrome accompanied by a progressive decrease in haemoglobin. Computed tomography (CT) revealed two cystic tumours in the abdominal cavity. The patient was underwent transabdominal retroperitoneal tumour resection. During surgery, we found two retroperitoneal tumours-one contained approximately 9000 mL of dark red fluid and the other contained 1000 mL of light brown fluid. She has recovered well without any complications.
UNASSIGNED: There have been only a few reports of retroperitoneal leiomyomas with intratumoral bleeding. This case highlights the importance of recognizing intratumoral haemorrhage in patients with large leiomyomas and a progressive decrease in haemoglobin after ruling out external haemorrhage. If necessary, dynamic monitoring via CT may help clarify the diagnosis.

Minimally invasive percutaneous nephrolithotomy (mini-PCNL) maintains a stone clearance rate similar to standard PCNL while reducing blood loss. Bleeding is a complex and serious complication that can arise after PCNL surgery. Pseudoaneurysm (PA) is an uncommon type of delayed bleeding problem, which affects less than 1% of patients after PCNL. The most effective treatment for severe post-PCNL hemorrhage is super-selective renal angiographic embolization (SRAE), but it can fail in some patients and require additional surgical intervention. This report details the case of a male patient, 55 years old, who experienced severe bleeding four times and had three SRAE procedures and one laparoscopic procedure after PCNL. The presence of a renal artery pseudoaneurysm was not initially identified during the first two attempts of angiography due to arterial spasm and a small, undeveloped lesion. This case report is intended to enhance awareness of tiny pseudoaneurysms, emphasizing the importance of avoiding oversight to improve the success rate of embolization.

Surgery is the primary treatment of choice for tumours, and improves prognosis, prolongs survival and is potentially curative. Previous studies have described the effects of anaesthesia and changes in the neuroendocrine, circulatory and sympathetic nervous systems on postoperative cancer progression. There is growing evidence that intraoperative blood loss is an independent prognostic factor for tumour recurrence, postoperative inflammation is a predictor of cancer prognosis, and immunosuppressive status correlates with the degree of surgical damage. This paper outlines the potential mechanisms by which blood loss, surgical trauma and postoperative immunosuppressive status contribute to tumour growth and recurrence by reducing intraoperative haemorrhage and perioperative immunotherapy, thereby reducing tumour growth and recurrence, and improving long-term prognosis.

OBJECTIVE: Caveolin-1 (Cav-1) is reported to mediate blood-brain barrier integrity after ischaemic stroke. Our purpose was to assess the role of circulating Cav-1 levels in predicting symptomatic intracranial haemorrhage (sICH) amongst ischaemic stroke patients after endovascular thrombectomy (EVT).
METHODS: Patients with large-vessel occlusive stroke after EVT from two stroke centres were prospectively included. Serum Cav-1 level was tested after admission. sICH was diagnosed according to the Heidelberg Bleeding Classification.
RESULTS: Of 325 patients (mean age 68.6 years; 207 men) included, 47 (14.5%) were diagnosed with sICH. Compared with patients without sICH, those with sICH had a lower concentration of Cav-1. After adjusting for potential confounders, multivariate regression analysis demonstrated that the increased Cav-1 level was associated with a lower sICH risk (odds ratio 0.055; 95% confidence interval 0.005-0.669; p = 0.038). Similar results were obtained when Cav-1 levels were analysed as a categorical variable. Using a logistic regression model with restricted cubic splines, a linear and negative association of Cav-1 concentration was found with sICH risk (p = 0.001 for linearity). Furthermore, the performance of the conventional risk factors model in predicting sICH was substantially improved after addition of the Cav-1 levels (integrated discrimination index 2.7%, p = 0.002; net reclassification improvement 39.7%, p = 0.007).
CONCLUSIONS: Our data demonstrate that decreased Cav-1 levels are related to sICH after EVT. Incorporation of Cav-1 into clinical decision-making may help to identify patients at a high risk of sICH and warrants further consideration.

OBJECTIVE: Many countries have detailed recommendations for haemophilia patients to reduce the risk of vaccination-related bleeding. However, data from developing countries are lacking. We investigated scheduled vaccinations and vaccination-related bleeding complications in Chinese children with haemophilia and analysed issues related to vaccinations.
METHODS: Children with haemophilia in the PUMCH Haemophilia Treatment Centre were contacted via telephone. We distributed a vaccination questionnaire to their parents. The severity of haemophilia, coagulation factor infusions before vaccination, injection mode, and vaccination-related complications were analysed.
RESULTS: A total of 440 valid questionnaires were received from 27 of 34 provinces in China. 31.3% (138/440) of the children with haemophilia did not receive all of their vaccinations. Among the children who received vaccinations, 48.1% (197/409) experienced bleeding complications. In patients with severe haemophilia, those on regular prophylaxis had a lower incidence of local hematoma compared to those on intermittent or no prophylaxis (14.3% vs. 26.5% vs. 39.7%, P < 0.05). The incidence of local hematomas was lower by subcutaneous (SQ) injections than by intramuscular injections (24.6% vs. 35.3%, P < 0.05).
CONCLUSIONS: The vaccination rate is quite insufficient in Chinese children with haemophilia. Missed vaccinations are related to vaccination-related bleeding complications. Prophylaxis before vaccination and SQ injections would help reduce bleeding complications.

Sacrospinous ligament fixation (SSLF) is widely applied to the treatment of female pelvis organ prolapsed. Contradictory findings have already been reported in the comparison of sacrocolpopexy (SC) with SSLF. The objective of this study is to evaluate the efficacy of SC versus SSLF in treating pelvis organ prolapsed after operation. We conducted a meta-analysis of both operative approaches, including PubMed, Embase, and Cochrane Library. In this research, 822 articles were chosen from three databases, 201 were copied, and 10 were included. Among them, 7248 cases were operated on the prolapsed pelvis. It was found that SSLF surgery could significantly decrease the rate of postoperative wound infection after operation (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.42-0.82; p = 0.001). No statistical significance was found among the SSLF and the SC surgery for the post-operation haemorrhage of the patient (OR, 0.81; 95% CI, 0.23-2.83; p = 0.75). No statistical significance was found among the SSLF and the SC surgery for the postoperative period of the patient\'s operation (mean difference, -15.46; 95% CI, -52.87 to 21.94; p = 0.42). Applying SSLF surgery to treat pelvic prolapse in women may benefit from a reduction in the number of post-operative wound infections. However, SSLF had no statistical significance with respect to the amount of haemorrhage after operation or operation time.

At present, it is regarded as a safe and efficient operation to treat terminal pancreatic disease. In this paper, we present a summary of the results of the clinical trials that have been conducted to evaluate the efficacy of laparoscopic and open-access pancreatic resection for pancreatic carcinoma of the end of the pancreas. Systematic review of the comparison between laparoscopy and open-access pancreatic resection was conducted. Comparative studies published before October 2023 were included. The selection of the studies was done according to a particular classification and exclusion criterion. A few of our results, which were post-surgery, were associated with injury, were compared. Where appropriate, the reliability of the data has been corroborated by a sensitive analysis. Six trials of 2075 patients with pancreatic cancer who underwent distal pancreatic resection to be included in the definitive data analysis. Among them, 447 were treated with open-access surgery and 296 were treated with laparoscope. Six trials showed that there was no statistically significant difference in the risk of postoperative wound infection in patients with pancreas cancer who received a distal pancreatectomy between laparoscopy and open surgery(OR, 1.66; 95% CI, 0.76-3.61 p = 0.20). Four trials did not reveal any statistically significant differences in the risk of postoperative haemorrhage among patients with pancreas cancer who received a distal pancreatectomy between laparoscopy and open surgery (OR, 1.84; 95% CI, 0.54-6.26 p = 0.33). Both trials did not reveal any statistically significant difference in the duration of operation for patients with pancreas cancer who received a distal pancreatectomy between laparoscopy and open surgery (MD, 13.58; 95% CI, -7.31-34.46 p = 0.2). Based on these meta-analyses, the use of laparoscopy or open surgery was not associated with an increase in the risk of postoperative infection or haemorrhage. Furthermore, the duration of the two operations did not differ significantly. These two procedures appear to be a safe and viable choice in the treatment of pancreatic carcinoma. Nevertheless, a randomized, controlled study should be performed to verify the validity of this observation.

OBJECTIVE: To explore the feasibility of using marking and fusion image-guided technique with cone-beam CT (CBCT) in cases of kidney ruptured haemorrhage without extravascular leakage in digital subtraction angiography (DSA) images.
METHODS: This is a retrospective case-control study that included 43 patients who underwent transcatheter arterial embolization for kidney ruptured haemorrhage and difficult haemostasis. The patients were divided into two groups: the CBCT group (cases without extravascular leakage observed in angiography) and the control group (cases with clearly identifiable target vessels in angiography). The baseline characteristics and clinical outcomes were collected and analysed.
RESULTS: The results showed no statistically significant differences in the duration of the procedure and intraoperative blood transfusion between the control and CBCT groups (P > .05). The study clarified that the CBCT group had a significantly higher rate of improvement of gross haematuria compared to the control group (P < .05). The CBCT group showed a greater increase in haemoglobin and a lesser increase in creatinine. The clinical success rates were 87.5% in the control group and 90.9% in the CBCT group (P > .05).
CONCLUSIONS: The marking and fusion image-guided technique is useful in cases of kidney ruptured haemorrhage without extravascular leakage of contrast agent. The technique is safe, feasible, and effective, and we believe it is superior to purely DSA-guidance.
CONCLUSIONS: The use of the marking and fusion image-guided technique is recommended to overcome the challenge of undetectable target vessels during interventional procedures. This technique is considered as non-inferior to purely DSA-guided interventional procedures where the target vessels are clearly identifiable.

The effect of obesity on wound-related outcomes in post-ovarian cancer patients is not clear. A number of studies on the association of fat with post-operation injury in ovarian carcinoma have produced contradictory findings. This study aims to conduct a study of the available data to assess the association of obese individuals with significant surgery results in ovarian cancer. We looked up Cochrane Library, Embase, and PubMed for qualifying research on ovarian cancer operations to determine the primary evidence for evaluating the association of obesity with post-surgical wound injury in ovarian cancer. The odds ratio (OR) was analysed with a fixed effect model if the variability of the study was small; otherwise, the analysis of the data was done with a random effect model. Out of 1259 related trials which were reviewed for eligibility, 6 publications were chosen from 2009 to 2019, 3076 patients who had had an operation for ovarian cancer. Obesity has been linked to an increased rate of wound-related complications in ovarian cancer operations compared to those without obesity (OR, 0.50; 95% CI, 0.37, 0.69 p < 0.0001). Non-obesity was significantly less likely to occur with respect to operation time compared to those with obesity (MD, -48.00; 95% CI, -55.33, -40.68 p < 0.00001). There were no statistically significant differences in the rate of haemorrhage after the operation (OR, 0.26; 95% CI, 0.04, 1.57, p = 0.14). Because of the limited number of trials in this meta-analysis, caution should be exercised in their treatment. More high-quality research with a large sample is required in order to confirm the findings.

Pulmonary sarcomatoid carcinoma (PSC) is a rare and highly invasive malignant tumour. It has similar clinical manifestations and imaging features to ordinary lung cancer. This current case report describes a 65-year-old male patient who had a mass in the apicoposterior segment of the left upper lobe with haemoptysis. Imaging studies revealed a central parenchymal mass surrounded by areas of ground-glass opacity, strongly indicating the presence of a pulmonary malignancy. Intraoperatively, the tumour was discovered to have invaded the chest wall and exhibited a significant propensity for bleeding. Consequently, a left upper lobe resection accompanied by extensive pleural debridement were performed. Subsequent postoperative histopathological examination confirmed the diagnosis of PSC. Unfortunately, 1 month after the surgery, the patient presented with left-sided haemothorax. Despite employing various haemostatic interventions, the patient eventually succumbed to haemorrhagic shock. This study provides a treatment strategy reference for patients with PSC presenting as haemothorax.
