Introduction The authors introduce the history of liver surgery in Szeged on the occasion of the 100th anniversary of the Surgery Department's establishment. Material and methods After the initiation of liver surgery in Szeged by Professor Karácsonyi 1982 we are treating not only patients with benign and malignant focal liver diseases but also others with surgery required because of complications of portal hypertension. Patients are presented in two periods. Discussion We operated on 46.5% of the patients with malignant and 53.5% of the patients with benign diseases between 1981 and 1991. The surgical spectrum extended to trisegmentectomy. There were 14% of minor and 9.9% of major complications, the mortality was 3.23% which meets international standards. In the second period, 50.5% of the patients were operated on because of malignant and 46.5% of the patients suffered from benign focal diseases from 1992. Among the patients who had been operated on because of liver malignancy, there were 51% metastasis mostly of colorectal cancer, 22% were hepatocellular, 16% were cholangiocellular carcinoma and in 11% were other malignant tumors. In those patients who had been operated on because of benign focal liver diseases, there were 32% cysts, 25% echionococcus cysts, 26% haemangiomas, 8% adenomas, 7% FNH, and 2% because of others. The summarized mortality rate was 1.3%. There were peritoneo-venous shunt implantations in 126 cases because of therapy-refracter ascites. We performed oesophageal transection with a circular stapler after failed endoscopic haemostasis in 50 cases. Conclusion Chances of liver surgery have been basically widened because of the financial investment that is connected to the Department of Surgery's move to a new building. The liver unit in Szeged today can take care of patients in a full spectrum of liver surgery.

Introduction. Thymoma is the most common tumour of the anterior mediastinum. Video-Assisted Thoracic Surgery technique of thymoma resection is spreading world-wide, but the thoracoscopic method is still contentious in many ways. Authors evaluate the early and mid-term results of a 17 years period of VATS unilateral approach at 2 Hungarian thoracic surgical centers. Method. Depending on the anatomical situation of the thymoma, we performed thymectomy, or partial thymectomy (thymomectomy) for the Masaoka–Koga I–II–III stage thymoma from the right or left side through 2 or 3 intercostal ports. We managed the operations with ultrasonic dissector and electrocauter. By using international standards we evaluated perioperative morbidity, mid-term oncological results and clinical symptoms of myasthenia. Results. 23 of the 54 patients were man, 31 were woman, the average age was 58 (26–79) years, 23 of them had myasthenia. The conversion rate was 11,5% (7/61). The average operation time was 84 (39–150) minutes. The average hospitalisation time was 5.5 (3–19) days. The average size of the thymomas was 46 (18–90) mm. The histology resulted thymoma type A in 2 cases, AB in 19 cases, B1/2/3 in 11/11/1 cases, mixed B in 10 cases. The examination of the resection line was R0/1/2 in 42/11/1 cases. The Masaoka–Koga stages were: I (17), IIA (28), IIB (2), III (7). There was 25 thymomectomies, and 29 thymectomies. In seven cases there were extension of the operation to the pericardium (2), to the lung (2), to the phrenic nerve (6), and to innominate vein (1). The in-hospital mortality over 30 day was in 1 case (1.85%). The morbidity was 11/54 (20.4%). The average follow-up time was 62.56 (5–198) months. In the group with myasthenia the effectivity of the operation was 18/21 (85.7%), including complete remission of 5/21 (23.8%). Post-thymectomy myasthenia gravis developed in 2/31 cases (6.5%). The average 5 years survival was 100%, tumour-free 5 years survival was 96%. Conclusions. The higher proportion of the thymomectomy in the early results, higher conversion rate and lower R0 proportion might be in connection with the attitude of the surgeons, with the learning curve and with the limitations of the unilateral method. After a longer follow-up time late results may become more real and comparable. Instead of unilateral VATS technique we have changed to the subxyphoideal approach of VATS because of its better visualisation.

Since its introduction in 1991, laparoscopic splenectomy has been considered the gold standard in spleen surgery, and the advantages of this technique over open surgery are indisputable. The technique was initiated in the Department of Surgery, University of Szeged in 1994 and since then our working group has gained one of the greatest experiences in this field in Hungary. Based on our results, similarly to literature data, it may be established that laparoscopic splenectomy can be considered a surgical procedure with low morbidity after gaining the necessary experience. In our study, the bowel motility recovered earlier, and hospital stay was significantly shorter after laparoscopic procedures. We proved laparoscopic splenectomy is a safe method in cases of extremely large spleens, and the Pfannenstiel incision is a cosmetically acceptable alternative for the retrieval of the spleen. Although several medications are available for second-line ITP therapy, laparoscopic splenectomy provides the longest-lasting results. In our study, young age and a preoperative response to steroids (steroid-dependent cases) were positive predictors for the success of splenectomy. Based on our experiences in the case of an immediate complete response to splenectomy, relapse occurred significantly less often.

Introduction. Appendicitis is one of the most common causes of acute abdominal surgical indications. WHO declared the SARS-CoV-2 (COVID-19) virus infection a pandemic on the 11.03.2020., affecting all segments of healthcare. Management of the acute cases also faced new challenges as a result of the restrictive measures taken during the pandemic, affecting the population and healthcare providers. In our surgical department, during the medical care of those diagnosed with acute appendicitis, in the absence of uniform professional protocols, we often required individual considerations. In the absence of universal professional guidelines, during the medical care of those who had been diagnosed with acute appendicitis we often required individual considerations in our surgical department. Aim. the comparison of the time elapsed between the onset of the symptoms and the time the patients arrived to our surgical department, the frequency of hospitalisation and the frequency and difference between postoperative complications in patients diagnosed with acute appendicitis during the pre-pandemic period of SARS-CoV-2 and the III. wave of COVID-19. Methods. in our retrospective analysis we included those more than 18-years old patients who were diagnosed with the clinic-radiological picture of acute appendicitis during the pre-pandemic 6 months (16. 09. 2019. – 16. 03. 2020.) and the III. wave of COVID-19 (01. 11. 2020. – 01. 04. 2021.). We compared the length of time between the onset of symptoms and the beginning of hospitalisation, the complexity of appendicitis, the method of surgery used, the duration of hospitalisation and the development of postoperative complications. Statistical significance was examined by t-test and Fischer-test. Results. 64 patients were included, 47 in the pre-pandemic period and 17 in the III. wave of COVID-19. During the pandemic, the number of people diagnosed with acute appendicitis showed a declining trend, however the incidence of complicated appendicitis increased (26% « 35%). In the III. wave of COVID-19, the time between the onset of symptoms and the examination was 27,3 h longer on average (P = 0.275), the hospitalisation was 17.3 h longer (P = 0.412) and the postoperative complications (2.12% « 23.5%) and surgical conversions (0% « 21%) were also significantly different (P = 0.264), but there was no significant correlation in either case. Conclusion. although there was no significant correlation in our analysis, it appears that during the pandemic, patients sought medical attention later and with more severe symptoms, resulting in progression of acute appendicitis.

Introduction. Non-intubated spontaneous ventilated (NITS) minimally invasive surgery (video-assisted thoracic surgery VATS) is a widespread procedure, but there are some doubts regarding its safety. We developed a safe method, spontaneous ventilation with intubation (SVI) to resolve these concerns. In this study, the early postoperative results of the SVI sublobar resections are presented. Methods. Between 2020 May 25 and 2021 March 26, 20 SVI VATS sublobar resection was performed with a double lumen intratracheal tube. Results. Surgeries were performed for 9 females and 11 males with a mean age of 66.1. The mean BMI was 27.8, FEV1 was 89.1%, and Carlson Comorbidity score was 6.1. The mean surgical time was 61.5 min, drainage time was 1.85 days and hospital stay was 3.35 days. Morbidity was found to be 5%. Primer lung cancer was removed in 9 cases, we performed 6 metastasectomies and in 5 cases benign lesion was removed. Conclusion. According to the early postoperative results spontaneous ventilated VATS sublobar resections with double lumen intratracheal tube can be considered a safe thoracic surgical method.

The first Hungarian kidney transplantation was performed in 1962, in Szeged, by András Németh (1924–1999). The first semester at the university in Szeged started in 1921, so this year we celebrate the centenary. This event inspired authors to review the history of kidney transplantation in Szeged, remembering the first one and point of the cornerstones in the transplant program. The donor of the first Hungarian kidney transplantation was the brother of the recipient. The operation itself was technically successful, but the lack of immunosuppression caused graft rejection, and the patient died after 79 days. His brother, the donor was healthy, after 50 years, and he encouraged everybody to donate organs. The organized kidney transplant program started more than 10 years later, in 1973, in Budapest. The program was supported by the Ministry of Health. Szeged joined the program in 1979 led by Ernő Csajbók and Pál Szenohradszky. In the Transplant Center in Szeged, developed organizationally as well as professionally, 1701 kidney transplantation has been performed up to the end of the year 2021.
