ABSTRACT
A 63-year-old male presented to our clinic with computed tomography data of a large tumor of the left adrenal gland. The formation is highly suspicious for malignancy with central necrosis and hemorrhage, and a total size of 197/183/201 mm. Due to elevated D-dimer values of 7.17 mg/l (reference range <0.5 mg/l), treatment with dabigatran etexilate 2x150 mg was prescribed following a cardiology consult. On the third day of therapy, the patient noticed a large swelling in the left abdominal flank, which caused discomfort. No additional symptoms were reported. No previous abdominal surgical interventions or trauma were reported. Following a thorough physical examination, the patient was referred for a computer tomography that reported a diagnosis of a tumor of the left adrenal gland. Due to the size of the neoplasm, the suspicion of malignancy, compression of adjacent structures, and significant anemia with an Hb of 112 g/L, operative treatment was chosen as the best treatment modality. The mass was reported as a large organizing adrenal hematoma with no suspicion of malignancy on histology. Following a review of available literature, no other cases of unilateral adrenal hematoma with a size of 201x197 mm, following oral anticoagulant therapy with dabigatran etexilate, without any prior surgery or trauma have been reported. Most clinical cases report bilateral adrenal hemorrhage during the postoperative period, following prophylaxis with heparin and the development of heparin-induced thrombocytopenia. The patient underwent operative treatment, after which the patient recovered normally and was discharged from the clinic without complications.
ABSTRACT
The solid pseudopapillary tumor (SPT) is a rare pancreatic lesion that usually affects young and middle-aged patients and has a female predominance and low malignant potential. The exact histogenesis of this tumor is still unclear. We present the case of a 60-year-old female patient with occasional abdominal pain. Positron emission tomography/computed tomography (PET/CT) and magnetic resonance imaging (MRI) revealed a tumor mass in the pancreatic tail. Distal pancreatectomy and splenectomy were performed. The result from the pathology report was solid pseudopapillary neoplasm (SPN). The patient underwent four cycles of adjuvant chemotherapy with gemcitabine, which she tolerated well without complaints. A control computed tomography (CT) scan and PET/CT of the abdomen (five months after the operation) showed a cystic lesion suspicious for local recurrence in the pancreatic tail during the follow-up period. The patient underwent a second surgery operation. Subsequent histological examination showed chronic indurative pancreatitis, areas with steatonecrosis, lipogranulomas, and fibrosis without evidence of relapse. SPT is a rare pancreatic tumor that most commonly affects young women. Although the tumor has locally aggressive characteristics, the prognosis is excellent after surgical excision. Our case emphasizes that this tumor can occur not only in young women but also in older patients. Chronic granulomatous inflammation and indurative pancreatitis can sometimes mimic a relapse on CT and PET/CT image tests.
ABSTRACT
Background: Colorectal cancer is a major cause of morbidity and mortality in the world. Approximately, one of three diagnosed colorectal cancers is a rectal cancer. Recent developments in the field of rectal surgery have promoted the use of surgical robots, which are of great need when surgeons face anatomical difficulties, such as a narrowed male pelvis, bulky tumor, or obese patients. This study aims to evaluate the clinical results of robotic rectal cancer surgery during the introduction period of a surgical robot system. Moreover, the period of the introduction of this technique coincided with the first year of the COVID-19 pandemic. Methods: Since December 2019, the Surgery Department of the University Hospital of Varna has become the newest and the most modern Robotic Surgery Center of Competence in Bulgaria, equipped with the most advanced da Vinci Xi surgical system. From January 2020 to October 2020 a total number of 43 patients have underwent surgical treatment, of which 21 had roboticassisted procedures and the rest - open procedures. Results: Patient characteristics were close between the studied groups. The mean patient age in robotic surgery was 65 years, as six of these patients were females, while in case of open surgery these values were to 70 and 6, respectively. Two thirds (66.7%) of the patients operated on with da Vinci Xi were with tumor stage 3 or 4 and approximately 10% had the tumor located in the lower part of the rectum. The median value of the operation time was 210 min, while the length of hospital stay was 7 days. These short-term parameters were not found to have a large difference in respect to the open surgery group. A significant difference is depicted for the number of lymph nodes resected and the blood loss, with both parameters demonstrating advantage for the robot-assisted surgery. The blood loss is more than twice less than the case of open surgery. Conclusions: The results confidently showed the successful introduction of the robot-assisted platform in the surgery department despite the limitations caused by the COVID-19 pandemic. This technique is expected to become the main choice of minimally invasive technique applied to all types of colorectal cancer surgery in the Robotic Surgery Center of Competence.
