Transarterial embolization followed by staged hepatectomy versus emergency hepatectomy for ruptured HCC: a meta-analysis

Background To compare the efficacy and safety between emergency hepatectomy (EH) and emergency transarterial embolization (TAE) followed by staged hepatectomy (SH) in the treatment of spontaneous ruptured hepatocellular carcinoma (rHCC). Methods Databases (PubMed, EMBASE, Web of science, Cochrane Library, ClinicalTrial.gov, CNKI, Wanfang and VIP) were searched for all relevant comparative studies from January 2000 to October 2020. Odds ratio (OR) and mean difference (MD) with 95% confidence interval (CI) were pooled for dichotomous and continuous variables, respectively. Subgroup analyses based on the kind of embolization were conducted. RevMan 5.3 software was adopted for meta-analysis. Results Eighteen studies with 871 patients were finally included in this meta-analysis, 448 in EH group and 423 in TAE + SH group. No significant difference was observed in successful hemostasis (P = 0.42), postoperative hospital stay (P = 0.12), complication rate (P = 0.08) between EH and TAE + SH group. However, TAE + SH group was associated with shorter operating time (P < 0.00001), fewer perioperative blood loss (P = 0.007), fewer blood transfusion (P = 0.003), lower in-hospital mortality (P < 0.00001) and higher 1-year survival as well as 3-year survival (P < 0.0001; P = 0.003) compared with EH group. Conclusion Compared with EH, TAE + SH could reduce perioperative operating time, blood loss, blood transfusion, mortality rate and increase the long-term survival rate of the rHCC patients, which may be a better treatment for resectable rHCC (AU)

Spontaneous rupture of a solitary oligometastatic hepatic melanoma.

A mid-50s woman presented with acute right upper quadrant pain 1-day post second cycle of pembrolizumab. She has a significant history for two concurrent malignancies: a solitary oligometastatic hepatic melanoma (NRAS mutant) of unknown primary diagnosed 2 months prior, and a 10-year history of breast carcinoma with pulmonary metastases on palliative chemotherapy. Multiphase CT scan demonstrated active venous bleeding without active arterial bleeding. The patient received two units of packed red blood cells, followed by selective transcatheter arterial embolisation (TAE) of the right hepatic artery branches to segment 7 and 8. Spontaneous rupture of solitary liver metastases are exceedingly rare. TAE is a safe and effective treatment choice in patients with spontaneous rupture. Given progressive tumour burden, changes in management with a different immunotherapy agent can be considered.

The Importance of Nodule Size in the Management of Ruptured Thyroid Nodule After Radiofrequency Ablation: A Retrospective Study and Literature Review.

Background: Nodule rupture is a relatively uncommon yet severe complication of radiofrequency ablation (RFA). When nodule rupture occurs, determining suitable therapeutic management is a critical issue. A study herein aimed to identify the predictive factors affecting the management of post-RFA nodule rupture. Methods: Post-RFA nodule rupture data of 9 patients were enrolled from 2 medical centers. A literature investigation was performed, uncovering nodule rupture data of 17 patients. A total of 26 patients were analyzed and divided into two groups, categorized as patients requiring either invasive or conservative therapeutic management. Data including initial symptoms, imaging, therapeutic management, and prognosis were reviewed and compared between the two groups. Results: Significant differences in nodule diameter, and the ablation time of the course prior to rupture (RUP time) were noted between the two groups (p = 0.045 and 0.008, respectively). Logistic regression analysis indicated the initial nodule diameter and RUP time significantly affected the requirement of invasive treatment (OR 1.99 and 1.11, respectively). Considering practicality, when a nodule with an initial maximum diameter of >4.5cm ruptured, invasive management was suggested (sensitivity 69% and specificity 79%). Conclusion: Though nodule ruptures can be managed conservatively, a ruptured nodule with an initial maximum diameter of >4.5cm may require invasive management. Understanding the significant clinical and imaging features will help physicians make an appropriate risk assessment to determine the correct treatment in a timely manner.

Shock caused by spontaneous rupture uterine vessels during puerperal period: a case report and literature review.

Hemoperitoneum caused by spontaneous rupture of uterine vessels during delivery is relatively rare in obstetric hemorrhage, and even rarer during the puerperal period. It can be life-threatening without timely diagnosis and treatment; therefore, the literature on this topic is very scarce. To explore its etiology and identify its diagnosis and treatment principle, we are reporting a case of shock caused by spontaneous rupture of uterine vessels admitted in our hospital. Its etiology is still unknown, its presenting symptoms are commonly unspecific, and its diagnosis is often made during the surgery. The rupture of uterine vessels during pregnancy should be differentiated from placental abruption, uterine rupture, placenta implantation through the uterus, and abdominal organ rupture. Active and timely operative intervention can prevent the mortality. This case stresses the need for careful post-delivery monitoring for revealed postpartum hemorrhage. We will discuss possible etiologies of uterine vessels rupture during pregnancy, associated imaging findings, and management options.

Successful conservative management of a spontaneous intraperitoneal urinary bladder rupture secondary to benign prostatic hyperplasia: a case report.

A spontaneous intraperitoneal bladder rupture is a rare, serious and life-threatening surgical emergency of various etiologies, with unspecific clinical presentation, and difficult diagnosis. Surgical treatment is the standard therapy for intraperitoneal bladder rupture; however, there is an increasing tendency toward conservative management in selected patients with favorable characteristics. Herein, we report a rare case of a 65-year-old male patient presented to the emergency department with intraperitoneal bladder rupture following an episode of acute urinary retention due to benign prostatic hyperplasia, and which was successfully managed conservatively with urinary bladder catheterization and antibiotic therapy, without any complication.

Spontaneous rupture of a renal artery pseudoaneurysm in a hemodialysis patient: A case report.

RATIONALE: Renal artery pseudoaneurysm is a rare vascular lesion usually caused by trauma or percutaneous urological procedures. Spontaneous rupture of pseudoaneurysms without predisposing events, especially in hemodialysis patients, has rarely been reported. PATIENT CONCERNS: A 25-year-old man receiving maintenance hemodialysis visited the emergency room because of sudden severe right flank pain. He had no history of trauma or urological procedures except for a left renal biopsy to diagnose Alport syndrome 10 years prior. DIAGNOSIS: Contrast-enhanced computed tomography revealed a right perirenal hematoma with pseudoaneurysms. INTERVENTIONS: On renal angiography, multiple pseudoaneurysms were observed in the right renal artery branches and embolization was performed. OUTCOMES: Post-angiography showed no pseudoaneurysms. His abdominal pain improved, and he was discharged 2 weeks after embolization. LESSONS: When maintenance dialysis patients complain of severe abdominal pain, spontaneous rupture of a renal pseudoaneurysm should be considered as a differential diagnosis, even if the patient has no history of trauma or previous urological procedures.

Spontaneous Rupture of a Huge Presacral Tarlov Cyst Leading to Dramatic Neurologic Recovery.

BACKGROUND: This manuscript discusses the case of huge presacral Tarlov cysts (TCs) and the substantial neurologic recovery noted in the patient following spontaneous rupture of the most prominent cyst. Perineural or TCs are nerve root cysts, which are usually incidental findings on magnetic resonance imaging (MRI) and are most frequently observed in the sacral spine. Symptomatic lesions are rarely encountered. CASE DESCRIPTION: In this case, a 44-year-old woman presented with anal and vulva pain on the right side, and bladder and bowel dysfunction. MRI of the lumbosacral spine showed multiple huge bilateral TCs located within the presacral space from S1-3. There was a substantially large right-sided S3 cyst that was presumed to be responsible for her symptoms. Surgical intervention was considered; however, her symptoms improved significantly during the waiting period for surgery because of spontaneous rupture of the right-sided S3 cyst, as confirmed on follow-up MRI. On follow-up over a 1-year period, the patient had been very well with no recurrent symptoms. CONCLUSIONS: To our knowledge, this is the first report of spontaneous cyst rupture and resultant neurologic improvement in a case of symptomatic presacral TCs.

Preoperative Wilms tumor rupture in children.

PURPOSE: According to the guidelines of International Society of Pediatric Oncology (SIOP) and National Wilms Tumor Study (NWTS), Wilms tumor with preoperative rupture should be classified as at least stage III. Few clinical reports can be found about preoperative Wilms tumor rupture. The purpose of this study was to investigate our experience on the diagnosis, treatment and prognosis of preoperative Wilms tumor rupture. METHODS: Patients with Wilms tumor who underwent treatment according to the NWTS or SIOP protocol from January 2008 to September 2017 in Beijing Children's Hospital were reviewed retrospectively. The clinical signs of preoperative tumor rupture were acute abdominal pain, and/or fall of hemoglobin. The radiologic signs of preoperative tumor rupture are as follows: (1) retroperitoneal and/or intraperitoneal effusion; (2) acute hemorrhage located in the sub-capsular and/or perirenal space; (3) tumor fracture communicating with peritoneal effusion; (4) bloody ascites. Patients with clinical and radiologic signs of preoperative tumor rupture were selected. Patients having radiologic signs without clinical symptoms were also selected. The clinical data, treatments and outcomes were analyzed. Meanwhile, patients without preoperative Wilms tumor rupture during the same period were collected and analyzed. RESULTS: 565 Patients with Wilms tumor were registered in our hospital. Of these patients, 45 patients were diagnosed with preoperative ruptured Wilms tumor. All preoperative rupture were confirmed at surgery. Spontaneous tumor rupture occurred in 41 patients, the other 4 patients had traumatic history. Of the 45 patients, 41 were classified as stage III, 3 patients with pulmonary metastases were classified as stage IV, and one patient with bilateral tumors were classified as stage V. Of these patients with preoperative tumor rupture at stage III, 30 patients had clinical and radiologic signs of tumor rupture, the other 11 patients had radiologic signs without clinical symptoms. Among the 41 patients at stage III, 13 patients had immediate surgery without preoperative chemotherapy (immediate group), and 28 patients had delayed surgery after preoperative chemotherapy (delayed group). In immediate group, 12 patients had localized rupture, 1 patient underwent emergency surgery because of continuous bleeding. In delayed group, 4 had inferior vena cava tumor embolus (1 thrombus extended to inferior vena cava behind the liver, three thrombi got to the right atrium), 4 crossed the midline with large tumors, 20 had extensive rupture without localization. In immediate group, tumor recurrence and metastasis developed in 2 patients, and no death occurred. In the delayed group, tumor recurrence and metastasis developed in 8 patients, and 7 patients died. During the same period, 41 patients were classified as stage III without preoperative rupture. In the non-ruptured group, tumor recurrence and metastasis developed in 3 patients, and 4 patients died. The median survival time in the ruptured group (both immediate group and delayed group) and non-ruptured group were (85.1 ± 7.5) and (110.3 ± 5.6) months, and the 3-year cumulative survival rates were 75.1% and 89.6%, respectively. The overall survival rate between the ruptured and non-ruptured groups showed no statistic difference (P = 0.256). However, there was significant difference in recurrence or metastasis rate between the ruptured and non-ruptured groups (24.4% vs 7.3%; P = 0.031). CONCLUSION: Contrast-enhanced computed tomography (CT) and ultrasonography (US) are of major value in the diagnosis of preoperative tumor rupture, and immediate surgery or delayed surgery are available therapeutic methods. The treatment plan was based on patients' general conditions, tumor size, position and impairment degree of tumor rupture, extent of invasion and experience of a multidisciplinary team (including surgeon and anesthesiologists). In our experience, for ruptured preoperative tumor diagnosed with stage III, the criteria for immediate surgery are as follows: tumor not acrossing the midline, tumor without inferior vena cava thrombus, localized rupture, being capable of complete resection. Selection criteria for delayed surgery after preoperative chemotherapy are as follows: large tumors, long inferior vena cava tumor thrombus, tumors infiltrating to surrounding organs, unlocalized rupture, tumors can not being resected completely. Additionally, patients with preoperative Wilms tumor rupture had an increased risk of postoperative recurrence or metastasis.

Comprehensive Treatment Strategy for Internal Carotid Artery Blowout Syndrome Caused by Nasopharyngeal Carcinoma.

OBJECTIVE: To evaluate a treatment strategy for internal carotid artery blowout syndrome caused by nasopharyngeal carcinoma. STUDY DESIGN: A retrospective analysis of a case series was performed. SETTING: Carotid blowout syndrome is a catastrophic complication caused by malignant tumor of the skull base. METHODS: A retrospective analysis based on 69 patients with internal carotid artery blowout syndrome admitted to our center between April 2018 and January 2020 was performed. The patients were divided into 2 groups: an EBBA (internal carotid artery embolization + bypass based on American Society of Intervention and Therapeutic Neuroradiology/Society of Interventional Radiology [ASITN/SIR]) group and an embolization/stent group. The follow-up time was 6 to 9 months. RESULTS: In the EBBA group, 41 patients (41/49, 83.7%) survived. Forty patients had a satisfactory quality of life after 3 months. No death occurred within 3 months. Nonoperative death occurred in 8 cases (8/49, 16.3%). The rate of mortality and disability was 18.4% (9/49). In the embolization/stent group, 16 patients (16/20, 80%) survived. Nonoperative death occurred in 4 cases (4/20, 20%), 3 of which occurred within 1 to 3 months. Four cases reported Modified Rankin Scale ≥2 after 3 months. The rate of mortality and disability was 40% (8/20). CONCLUSION: A comprehensive revascularization strategy for internal carotid artery (ICA) embolization and intracranial and extracranial bypass grafting based on ASITN/SIR score for ICA blowout syndrome patients not only can prolong the patient survival but also greatly improve the survival probability and quality of life as well as reduce their rate of mortality or disability.

Ruptured functioning adrenal tumour, atypical presentation with renal colic and hypertension.

Pheochromocytomas are uncommon tumours that originate in chromaffin cells. They are a representation of 0.1%-1% of all cases of secondary hypertension. Most pheochromocytomas are unilateral and benign, featuring catecholamine production, as well as the production of other neuropeptides. Pheochromocytomas are mostly located in the adrenal gland; the frequency of occurrence is highest between 30 and 50 years of age; however, up to 25% of cases may be linked to multiple endocrine neoplasia type 2, Von-Hippel-Landau disease and type 1 neurofibromatosis in the young.We present a case of ruptured left adrenal pheochromocytoma with an atypical presentation. A 30-year-old male patient presented with severe left flank pain and hypertension. The CT scan of the abdomen showed bleeding from the left adrenal mass, where resuscitation and angioembolisation were done. Embolisation of the inferior and superior arteries was done, but the middle failed. The patient experienced a significant drop in haemoglobin and a haemorrhagic shock post angioembolisation, which called for emergency laparotomy. The patient is currently doing well with an uneventful postoperative course.

ABSTRACT Introduction: Esophageal perforation is one of the most serious and difficult emergencies that a surgeon has to face due to the characteristics and location of the organ. Such prognosis depends mainly on the speed of the diagnosis and the choice of treatment established initially. Objectives: To present a case with such syndrome and to review the literature to update the therapeutic approach of this entity given its high mortality. Clinical case: Male patient in the fifth decade of life who presented for chest pain after an emetic condition. After a radiographic study, a spontaneous rupture of the esophagus or Boerhaave syndrome was diagnosed. Conclusions: The appropriate therapeutic approach associated with the early and timely diagnosis of the syndrome guarantees better survival rates(AU)

Contralateral spontaneous rupture of the esophagus following severe emesis after non-intubated pulmonary wedge resection.

BACKGROUND: Non-intubated thoracoscopic lung surgery has been reported to be technically feasible and safe. Spontaneous rupture of the esophagus, also known as Boerhaave's syndrome (BS), is rare after chest surgery. CASE PRESENTATION: A 60-year-old female non-smoker underwent non-intubated uniportal thoracoscopic wedge resection for a pulmonary nodule. Ultrasound-guided serratus anterior plane block was utilized for postoperative analgesia. However, the patient suffered from severe emesis, chest pain and dyspnea 6 h after the surgery. Emergency chest x-ray revealed right-sided hydropneumothorax. BS was diagnosed by chest tube drainage and computed tomography. Besides antibiotics and tube feeding, a naso-leakage drainage tube was inserted into the right thorax for pleural evacuation. Finally, the esophagus was healed 40d after the conservative treatment. CONCLUSIONS: Perioperative antiemetic therapy is an indispensable item of fast-track surgery. Moreover, BS should be kept in mind when the patients complain of chest distress following emesis after thoracic surgery.

"Hepatic rupture in preeclampsia and HELLP syndrome: A catastrophic presentation".

The objective of index study is to review the available literature on hepatic rupture or hematoma in hypertensive disorders of pregnancy to find the incidence, associated risk factors, clinical presentation, mode of management and feto-maternal outcome. Electronic database was searched using hepatic rupture or hematoma in pregnancy, preeclampsia, eclampsia, and HELLP syndrome (Hemolysis, EL: elevated liver enzymes, LP: low platelet count) as key words and literature published since January, 2000 to December, 2018 which met the inclusion criteria was reviewed. A total of 56 articles were reviewed describing 93 cases of hepatic hemorrhage in hypertensive disorders of pregnancy. Treatment varied from conservative management to abdominal packing, hepatic artery embolization, and partial hepatectomy to liver transplantation. Seven out of 93 patients with liver rupture met mortality and in one of them diagnosis was established on autopsy. Unawareness of the hepatic rupture in pregnancy by an obstetrician demands high index of suspicion for diagnosis and requires specialized, focused and exhaustive management for optimal feto-maternal outcome. Laparotomy and perihepatic packing is a viable option in patients with unstable vitals and is feasible even in limited resource settings.Short interval between diagnosis and management may enhance the feto-maternal survival rate and prevent further morbidity or mortality.

Failed angioembolization of a ruptured liver hemangioma complicated by iatrogenic injury of subclavian vein during catheter insertion.

In this study, we report a case of failed angioembolization of a ruptured liver hemangioma complicated by iatrogenic injury of the subclavian vein during catheter insertion. A 30-year-old woman experienced blunt trauma upon falling from her bed. Laceration of a seemingly preexisting hepatic hemangioma was diagnosed. No other injury was detected during a preoperative diagnostic workup. Subclavian vein catheterization was performed, followed by angioembolization to control bleeding due to the ruptured hemangioma. After angioembolization, the patient's systolic blood pressure and hemoglobin levels were 70 mmHg and 5.3 g/dL, respectively. She underwent emergency laparotomy. During the surgery, a large volume of blood in the abdominal cavity due to profuse bleeding from the ruptured hemangioma was observed. Because of a hemothorax found on chest radiography, we performed thoracoscopy, which revealed a large volume of blood in the right thoracic cavity and perforation of the subclavian vein by the catheter. After the damage-control surgery, the patient recovered safely. In this case, ruptured liver hemangioma complicated by subclavian vein catheter-related injury was treated safely using damage-control surgery. The catheter-related injury could be identified and treated using thoracoscopy.

Full recovery of near complete tear of anterior cruciate ligament without surgery: a case report.

INTRODUCTION: The anterior cruciate ligament (ACL) is the region where spraining or tearing is most prevalent when the knee is injured. Complete ACL ruptures have a much less favorable outcome without surgical intervention. Polydeoxyribonucleotide (PDRN) is a relatively safe substance widely used for regenerative therapy. PATIENT CONCERNS: A 43-year-old female patient visited our clinic with Rt. knee pain after slipping, which she rated as 7/10 on a numeric rating scale. DIAGNOSIS: She was diagnosed as having a near complete tear of the ACL at the femoral attachment, partial tear of the lateral collateral ligament. INTERVENTIONS: Ultrasound-guided PDRN injections were carried out 5 times at intervals of about 2 weeks. OUTCOMES: At 3-month follow-up, the patient demonstrated an improvement in knee symptoms (numeric rating scale 0) and ROM without any complications. Even after 2 years and 5 months since the diagnosis, she has been doing her daily life well without any pain. CONCLUSION: This is the first report of successful PDRN injection for near complete tear of ACL and partial tear of lateral collateral ligament without surgery.

Successful conservative management of a spontaneous intraperitoneal rupture of bladder diverticulum in a critical patient: A case report. A CARE-compliant article.

RATIONALE: A spontaneous rupture of the bladder diverticulum in an adult patient is extremely rare. The recommended treatment is surgery. However, some cases can be successfully treated with urinary catheterization, antibiotics, and/or percutaneous peritoneal drainage. In this case report, a spontaneous rupture of the bladder diverticulum was successfully treated non-surgically because it was deemed too risky for surgical intervention, such as non-ST segment elevation myocardial infarction (NSTEMI). PATIENT CONCERNS: A 76-year-old man presented with abdominal pain, distention, diarrhea, and oliguria for 3 days and hypotension for 1 day with no history of trauma. The patient showed direct and rebound tenderness in the lower abdomen. Computed tomography revealed an intraperitoneal bladder rupture associated with the bladder diverticula. Electrocardiography, echocardiography, and elevated cardiac enzyme suggested NSTEMI. DIAGNOSES: A spontaneous rupture of the bladder diverticulum, NSTEMI, and suspected sepsis due to gastroenteritis or urinary infection. INTERVENTIONS: The patient was treated conservatively with urinary catheterization and antibiotics for a bladder rupture and an infection. Percutaneous transluminal coronary angioplasty was performed for NSTEMI. OUTCOMES: The patient fully recovered without complications on hospitalization day 13. LESSONS: Conservative management might be an alternative for a spontaneous intraperitoneal bladder rupture in some cases. However, close observation is required, and surgical intervention is the first option for a spontaneous intraperitoneal rupture of the bladder diverticulum.
