Retroperitoneal trauma

A 38-year-old female with an etonogestrel implant in place and history of previous ectopic pregnancy presented with acute abdominal pain and vaginal bleeding. She was found to have a beta-hCG of >12,000 mIU/mL and free fluid noted on a focused assessment with sonography in trauma exam. She underwent an emergent diagnostic laparoscopy due to the suspicion of a ruptured ectopic pregnancy. Findings at the time of surgery included a normal-appearing uterus and left fallopian tube, a surgically absent right fallopian tube and large volume hemoperitoneum with a rapidly expanding left retroperitoneal hematoma...

AIM: To analyse the clinicoradiological characteristics of traumatic inferior vena cava (IVC) injury level on preoperative computed tomography (CT). MATERIALS AND METHODS: This retrospective study evaluated patients from a single trauma centre treated for traumatic IVC injury between January 2014 and January 2021. Data on demographics, mechanism of injury, Injury Severity Score, radiological findings on CT and angiography, IVC injury level in surgical findings, complications, and clinical outcomes were collected...

BACKGROUND: Necrotizing fasciitis (NF) is associated with a high mortality rate. Adequate incision and drainage and repeated debridement are necessary for NF management. After drainage, daily local irrigation should be performed. CASE PRESENTATION: A 72-year-old male patient complained of left lower quadrant pain. Computed tomography revealed a 7 cm mass in the descending colon, with retroperitoneal penetration. Hence, he underwent emergency surgery. The left abdomen was widely incised, and a transverse colostomy was performed for local wound control...

OBJECTIVE: To investigate the effect of laparoscopy on the diagnosis and treatment of closed abdominal injury. METHODS: A total of 26 patients with closed abdominal injury admitted to our hospital from January 2016 to January 2019 were searched. All patients were treated by laparoscopy. All patient reports were made with the informed consent of the patients. RESULTS: All patients were diagnosed clearly during operation. Among them, there were 3 cases of gastric perforation, 2 cases of liver rupture, 13 cases of spleen rupture, 3 cases of small intestine rupture, 1 case of liver round ligament laceration, 2 cases of small mesenteric vascular laceration, 1 case of colon liver mesenteric laceration, and 1 case of retroperitoneal hematoma...

Carcinoma of rete testis is an extremely rare malignant tumor arising from its epithelium. Prognosis is poor with mean survival of 8 months. Lymph node metastases and the size of the tumor larger than 5 cm are poor prognostic factors. We report a case of primary undifferentiated carcinoma of the rete testis in a 46-year-old man who presented with testicular enlargement without previous trauma or cryptorchidism, and with extensive peritoneal carcinomatosis, retroperitoneal lymph node metastases and fatal outcome...

A 53-year-old man suddenly developed chest and back pain while driving, resulting in an accident. Computed tomography revealed acute type A aortic dissection with malperfusion of the left lower extremity, retroperitoneal extravasation, hematoma in the anterior mediastinum, and ascites in the rectovesical pouch. Exploratory laparotomy before aortic repair revealed intestinal perforation and retroperitoneal bleeding, which were repaired, and an ascending aortic replacement was performed. Visceral trauma with active bleeding should be treated with priority, even if the need for systemic heparinization accompanies acute type A aortic dissection during surgery for aortic dissection...

By virtue of material differentiation capabilities afforded through dedicated postprocessing algorithms, dual-energy CT (DECT) has been shown to provide benefit in the evaluation of various diseases. In this article, we review the diagnostic use of DECT in the assessment of genitourinary diseases, with emphasis on its role in renal stone characterization, incidental renal and adrenal lesion characterization, retroperitoneal trauma, reduction of radiation, and contrast dose and cost-effectiveness potential. We also discuss future perspectives of the DECT scanning mode, including the use of novel contrast injection strategies and photon-counting detector computed tomography...

Complete uterine avulsion is an extremely rare complication of trauma sustained during pregnancy. We present the case of a 21-year-old nullipara at 16 weeks' gestation who was involved in a high-speed motor vehicle collision with subsequent fetal demise. Initially she was hemodynamically stable and demonstrated small amounts of intraabdominal free fluid, therefore multidisciplinary conservative measures were undertaken. However, as her condition worsened, she was taken for exploratory laparotomy, revealing complete gravid uterine avulsion at the level of the cervicoisthmic junction...

OBJECTIVE: To investigate the efficacy and safety of ultrasound-guided percutaneous intracystic deroofing for the treatment of simple renal cysts. METHODS: A retrospective study was conducted to analyze the clinical data of 46 patients with dorsal exophytic simple renal cysts treated at the First Affiliated Hospital of Nanchang University between February 2017 and June 2022. The patients were divided into two groups according to the surgical method, with 20 cases undergoing ultrasound-guided percutaneous intracystic deroofing being assigned to the observation group and 26 cases treated by retroperitoneal laparoscopic renal cyst removal included in the control group...

An arteriovenous-enteric fistula is a 3-way connection between the vascular and enteric system and associated with high mortality. We describe a case of iliac artery-inferior vena cava-duodenal fistula in a young female with a retroperitoneal mass presenting with sepsis and hemorrhagic shock with a catastrophic clinical course. These fistulas can be missed on endoscopy/colonoscopy and are usually diagnosed on computed tomography angiogram of the abdomen. Complex vasculoenteric fistula should be among differentials in patients presenting with gastrointestinal bleeding, especially with a history of malignancy, radiation, foreign bodies, and trauma...

BACKGROUND: Surgical approaches to the equine rectum and perirectal area are described in the literature. However, surgeries in this region can be challenging. OBJECTIVE: To describe the surgical anatomy of the presacral space and to evaluate its access using a retroperitoneoscopic approach. STUDY DESIGN: Ex vivo experiment. METHODS: Preliminary dissections were performed in two cadavers to define the boundaries of the presacral space and to determine portal locations for the surgical approach...

Splanchnic artery pseudoaneurysms are a known complication of necrotizing pancreatitis. Lumbar artery pseudoaneurysms are rare and usually associated with trauma, renal biopsy, or spinal procedures. We present a rare case of lumbar artery pseudoaneurysms as a complication of necrotizing pancreatitis. A 55-year-old man initially presented with necrotizing biliary pancreatitis complicated by peripancreatic necrotic fluid collections and walled-off necrosis requiring multiple endoscopic ultrasound-guided necrosectomies...

BACKGROUND:  Retroperitoneal and rectus sheath hemorrhage (RRSH) has been described as a potentially fatal condition with mortality rates of up to 30 % due to the risk of exsanguination in combination with often nonspecific clinical symptoms. Patients at risk are > 65 years of age as well as those receiving anticoagulation/antiplatelet medicine. Classifications based on etiology consist of trauma, surgery, and/or underlying vascular pathologies, though spontaneous occurrences without precipitating factors have been reported and are expected to increase with the high number of patients undergoing anticoagulant therapy...

Chylous ascites is an uncommon condition of accumulation of milky fluid rich in lymph and chylomicrons in the peritoneal cavity. Post-surgical complications following dissection near the base of the mesentery, retroperitoneum, or near the cisterna chyli, malignancies (e.g., pancreatic adenocarcinomas, lymphoma, gastric carcinoma), cirrhosis, and trauma are the prime causes of chylous ascites. Here we report a rare case of chylous ascites following clearance of isolated paraaortic nodal recurrence in a 28-year-old female with dysgerminoma of ovary...

UNLABELLED: The authors present the case of a 42-year-old male who was evaluated in a community hospital emergency department (ED) with right upper quadrant and flank pain after falling onto his couch. His evaluation included computed tomography (CT) of his abdomen with intravenous contrast that identified a large right retroperitoneal hematoma measuring an impressive 17 centimeters (cm) in length. The patient was transferred to a receiving trauma center. Upon arrival a focused assessment with sonography in trauma (FAST) ultrasound was obtained...

Here we present a rare case of life-threatening spontaneous renal haemorrhage following elective vascular surgery. A 73-year-old gentleman presents to the ED with acute onset right sided flank pain, 24 hours post bilateral renal artery stent insertion for renal artery stenosis. Subsequent angiography demonstrated bilateral renal artery stent occlusion with near complete bilateral kidney infarction. The patient urgently underwent bilateral renal artery thrombectomy. Post-operatively the patient developed severe unilateral flank pain and became haemodynamically unstable...

Traumatic pelvic injuries usually include high-energy crush injuries and are associated with significant morbidity and mortality. Mortality rates range from 6% to 15% and increase to 36%-54% in cases of fractures that result in increased pelvic volume. Therefore, retroperitoneal hemorrhage can spiral and progress to hemorrhagic shock. Pelvic hemorrhage most commonly occurs secondary to disrupted pelvic veins or fractured bones, and 10%-20% of cases involve arterial injuries. Owing to extensive bleeding and limitations of surgery for pelvic hemorrhage, interventional treatment is at the forefront of pelvic hemorrhage management...

A 63-year-old man presented with left abdominal pain, abdominal distention, and black stool following emotional stress and strenuous exercise. CT examination revealed a large cystic mass in the left abdominal cavity, as well as the presence of a teratoma in the hepatogastric space and a descending duodenal diverticulum. Subsequently, he underwent surgical resection, and the pathological findings indicated that the cyst wall consisted of mucinous glandular epithelium and smooth muscle, displaying a structure similar to normal intestinal wall tissue...

While rib fractures are common in blunt thoracic trauma, dislocations of the costovertebral joints (CVJs) are extremely rare and typically involve the first, eleventh, or twelfth rib. We report a rare case of dislocation of the left fourth and sixth CVJs in a 36-year-old man who was run over by a car. The rib heads were displaced anteriorly, abutting the aorta. Additional injuries included bilateral hemopneumothoraces, pneumomediastinum, pulmonary contusions, grade 3 splenic injury, left adrenal hematoma, retroperitoneal hematoma, Morel-Lavallée lesions at bilateral hips, and multiple fractures, including at the ribs and pelvis...

Appendicitis is the most common emergency abdominal surgery today. Although its common complications are well-known, retroperi-toneal abscess and scrotal abscess are rare and less known complications. In this study, we presented our patient who presented with appendicitis complicated with retroperitoneal abscess and scrotal fistula after appendectomy, and the literature review we conducted through PubMed. A 69-year-old man was admitted to the emergency department with complaints of abdominal pain, nausea-vomiting continuing for about 7 days, and fever and mental status change in the last 24 h...
