Incidental gallbladder cancer after cholecystectomy: 1990 to 2014

Introduction Cancer of the gallbladder is a serious diagnostic and therapeutic problem. According to the literature, 30% of cases are not confirmed before surgery. Other cases are detected incidentally by histopathology. Clinical trials and meta-analyses show that incidental gallbladder cancer (iGBC) occurs in 0.19%–2.8% of patients after cholecystectomy. The aim of this study was to analyze the incidence and severity of iGBC in cholecystectomy procedures performed in the surgical department at the 4th Military Teaching Hospital in Wroclaw during the years 1990–2014. Patients and methods In the years 1990–2014, a total of 7,314 cholecystectomies were performed in the surgical department because of cholecystolithiasis: 6,145 were performed using the laparoscopic approach (84.02%), 867 were performed as open surgery (11.8%), and 302 cases required conversion (5.1%). In this group, 5,214 of the patients were females (71.3%) and 2,100 were males (28.7%), with an average age of 54.7 years. Results We found 64 iGBC cases which were confirmed by histopathology. This represented 0.87% of all cases. In this group, 50 patients were females (78.1%) and 14 were males (21.8%), with an average age of 67.1 years. Of this group, 40 patients underwent a classic cholecystectomy, while 24 underwent laparoscopic procedures, out of which 13 cases ultimately required traditional surgery. The histopathology showed 15 carcinomas that were classified as G1 (23.4%), 28 were G2 (43.75%), and 21 were G3 (32.8%). Conclusion iGBC detected after a cholecystectomy due to cholecystolithiasis is a rare disease. We found iGBC in 0.87% of cases, which is on a comparable scale to the world literature. In the case of cancer, we frequently found it necessary to convert to an open surgical procedure. This cancer is more common in females and in people over 60 years of age.

An evaluation of the diagnostic efficacy of fine needle aspiration biopsy in patients operated for a thyroid nodular goiter

Background Thyroid cancer (TC) comprises 1% of all carcinomas and is the most common malignancy of the endocrine system. The disease is more common in women, with its peak morbidity observed in 40–50-year-old patients. The main risk factors include radiation, iodine deficiency, hereditary background, and genetic mutations. Among all diagnosed thyroid nodules, 5%–30% will evolve into cancer. The gold-standard procedure in the preoperative evaluation of a nodular goiter, apart from ultrasonography, is fine needle aspiration (FNA) biopsy. The FNA biopsy is favored for its simplicity, safety, and high specificity and sensitivity rates. Aim The aim of our study was to evaluate the clinical efficacy of FNA based on the patients’ register. Materials and methods In the Department of Surgery at the 4th Military Teaching Hospital in Wroclaw, 2,133 patients underwent thyroid surgery for thyroid goiter between 1996 and 2015. One hundred and eight cases of TC were diagnosed and of these, 66 patients had a preoperative FNA. Results Fourteen FNA biopsies (21%) revealed cancer, all of which were confirmed in the postoperative histopathology, although six cases of FNA-diagnosed cancer revealed a different histological type postoperatively. Eighteen FNA biopsies (27%) were suspected of being malignant. A disturbingly high rate of “benign” FNA biopsies (32 cases; 48%) revealed TC after surgery. Conclusion It is of great importance that the quality and quantity of FNA biopsies that are performed have been improved, especially due to the wide adoption of the Bethesda cytological evaluation system. FNA biopsy remains an obligatory and valuable diagnostic tool in thyroid nodules, but it is still insufficient as a standard procedure. A preoperative biopsy should always be related to all the available clinical data in order to provide the best treatment option for each patient individually.

Ex vivo pyelotomy, nephroscopy and holmium laser lithotripsy of a staghorn stone in a donor kidney prior to renal transplant

This case report presents the diagnostic and treatment procedures of stone removal from the kidney of a 67-year-old donor, the transplantation of the kidney to a 65-year-old recipient, and the postoperative course until the end of hospitalization. Computed tomography performed before collecting the organ showed a staghorn stone in the renal pelvis and lower calyces in the right donor kidney. The stones were removed ex-vivo using a rigid ureteroscope and a holmium laser prior to transplantation. Then the organ was transplanted to the left iliac fossa of a 65-year-old man with end-stage renal failure. The authors think there is a possibility of increasing the kidney pool, by using organs containing large calculi. In such cases stones should be removed before the operation and the patient should be monitored regularly, especially in the first months after the transplant.

Glomus Tumor of the Stomach - A Case Report and A Literature Review.

The study presented a case of a patient with a glomus tumor of the stomach, a mesenchymal neoplasm manifesting with upper gastrointestinal bleeding (Forrest IB). The patient was operated twice. First, he underwent elective laparotomy, during which Billroth I (Rydygiers method) gastric resection was performed. This his was followed by Billroth II resection with Brauns anastomosis. Histopathological examination revealed glomus tumor tissue. Literature data on the glomus tumor of the stomach are presented.

Giant saccular superior vena cava aneurysm-a rare and difficult clinical case.

A superior vena cava (SVC) aneurysm is an extremely rare case of vascular malformation in the chest cavity. This is a report of a case of a 57-year-old woman with a saccular SVC aneurysm which was 8 cm wide. The chest computed tomography (CT) scan confirmed a giant 75 mm × 79 mm × 81 mm mass containing the contrast medium from SVC, constricting the right lung parenchyma, narrowing the right innominate vein, in contact with the anterolateral chest cavity wall, and adjoining the superior mediastinum. Under general anesthesia and employing the median sternotomy approach, using a cardiopulmonary bypass (CPB), the venous aneurysm was successfully resected. The postoperative period was uneventful. Radical surgical resection using a sternotomy and a CPB is recommended.

The endovascular emergency treatment of an acute carotid artery dissection after Krav Maga training—a case report

Carotid artery dissection accounts for 20%–30% of all ischemic strokes in young patients aged <50 years. Recent guidelines on carotid disease management do not differentiate between traumatic and spontaneous dissection. We present a case of a 36-year-old male patient with the right internal carotid artery dissection treated with two XACT Abbot 6–8 mm × 40 mm stents placement after he was strangled during Krav Maga training. It is the most effective way to prevent the imminent stroke in the penumbral region. The safety and outcome of stent placement in internal carotid artery dissection remains unclear and further randomized trials are needed.

Ruptured Deep Femoral Artery Aneurysm: A Case Report

A deep femoral artery (DFA) aneurysm is a very rare pathology of the vascular system. Peripheral arterial aneurysms constitute 4.6% of all aneurysms, of which 0.13% are DFA aneurysms. In the literature, there are still few reports on this vascular system pathology. As a result, its diagnosis and treatment remain a serious clinical problem. This case study is of a 95-year-old patient admitted to our Department with anemia, swelling, and lower left leg pain. Generally, open surgery seems to be the treatment of choice for DFA aneurysms although the possibilities of intravascular therapy require further investigation.

Management of gastrointestinal stromal tumors: A 10-year experience of a single surgical department

BACKGROUND Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the digestive system. The primary location of GISTs is mainly the gastrointestinal system. Clinical symptoms are nonspecific and mainly depend on the location and size of the tumor. OBJECTIVES The aim of this study was to conduct a clinical and pathological analysis of 18 cases of GISTs from the medical records of the Department of Surgery at the 4th Military Teaching Hospital in Wrocław, Poland. MATERIAL AND METHODS The medical records were of women and men at the age of 36-84 years who were treated in the Surgical Clinic. The medical data that was gathered included clinical records, histopathological results and the type of surgical treatment. The study also encompassed the anatomical location and size of the tumor as well as microscopic examination of the tumor. RESULTS In most cases, GISTs were located in the stomach. The most common symptoms were stomachaches and signs of bleeding into the digestive system. Usually, the tumor presented a diameter of <5 cm and a low grade of malignancy. Out of 18 patients, 16 were treated with laparoscopic resection, whereas in the remaining 2 cases, multiorgan resections were carried out, because the tumor was locally advanced. CONCLUSIONS It is essential to distinguish stromal tumors from other mesenchymal tumors, since GISTs are among the cancers that have a high risk of malignant progression. The conditions for successful treatment are a properly established histopathological diagnosis, accompanied by immunohistochemical tests for CD117, and a combination of antibodies for a differential diagnosis of other mesenchymal tumors.

Carotid artery stenting versus endarterectomy for the treatmentof both symptomatic and asymptomatic patientswith carotid artery stenosis: 2 years’ experience in a high-volume center

BACKGROUND Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are the 2 current standard treatments for carotid artery stenosis. There is still no well-defined consensus with regard to their superiority. However, the minimally invasive nature of endovascular treatment makes CAS increasingly popular among vascular surgeons. OBJECTIVES The aim of the study is to compare the safety and efficacy of CEA and CAS in patients with symptomatic and asymptomatic carotid artery stenosis. MATERIAL AND METHODS A single-center, retrospective analysis of patients who were treated for carotid artery stenosis using CAS or CEA between January 2014 and December 2015 was carried out. There were 471 patients (266 CEA and 205 CAS) who were eligible for inclusion. The vast majority of the patients had significant (>70%) stenosis of the internal carotid artery (92.1% of CEA and 87.8% of CAS). The occlusion of the contralateral carotid artery was observed in 9.8% of all cases (2.6% of CEA vs 17.7% of CAS). RESULTS The occurrence of complications, such as stroke, myocardial infarction (MI) and death, did not vary statistically between the groups. There were 9 events of stroke in the CEA group (3.4%) and 8 in the CAS group (3.9%), 3 of which were fatal. There were no significant differences between the 2 groups (χ2 = 0.76; p > 0.05). There was no higher risk of mortality in any group (Fishers exact test; p = 0.08). Symptomatic patients had a higher incidence of stroke than asymptomatic patients across both groups (χ2 = 6.36; p < 0.05; hazard ratio 3.03 (1.26-7.33)). CONCLUSIONS Carotid endarterectomy is equally effective as CAS in stroke prevention, but is associated with a higher incidence of cranial nerve palsy, access site hematoma and other non-stroke complications. Symptomatic patients had a higher incidence of stroke, regardless of the treatment method.

Diagnosis and treatment of pelvic congestion syndrome: Single-centre experiences

BACKGROUND One of the underestimated causes of chronic pelvic pain (CPP) in women may be pelvic congestion syndrome (PCS) that is defined as the presence of varicose of ovarian and pelvic veins associated with chronic pain in the region of the pelvis. This pain is present longer than 6 months and intensifies with prolonged standing, coitus and menstruation. The disease constitutes a diagnostic as well as therapeutic problem, thus posing a challenge for the clinician. Transcatheter ovarian vein embolization might be a safe and effective option for PCS treatment. OBJECTIVES The objective of this study was to evaluate the efficacy of ovarian vein embolization ovarian as a method of the PCS treatment. MATERIAL AND METHODS Between 2002-2012, 11 embolization procedures were performed in 10 women (age range: 34-43; median age 39) with the diagnosis of PCS. One patient underwent embolization procedure twice. In 1 case the combined therapy of endovascular embolization and surgical phlebectomy of vulvar varices was performed. RESULTS There were no major intrainterventional complications. In all the patients (100%) a significant improvement in the clinical status was noted. The procedure improved the quality of life in the patients. Three women (30%) had a mild recurrence of the symptoms at mid-term follow-up. Among 8 women who had complained of dyspareunia prior to embolization 6 patients reported complete pain relief, in other 2 cases the pain subsided partially. There was a significant decrease in the severity of symptoms associated with hemorrhoids. CONCLUSIONS We consider embolization of insufficient ovarian veins an effective and safe way of treatment in a well-selected group of patients with PCS.
