Predictive Potential of RNA Polymerase B (II) Subunit 1 (RPB1) Cytoplasmic Aggregation for Neoadjuvant Chemotherapy Failure.

We aimed to investigate the contribution of co-translational protein aggregation to the chemotherapy resistance of tumor cells. Increased co-translational protein aggregation reflects altered translation regulation that may have the potential to buffer transcription under genotoxic stress. As an indicator for such an event, we followed the cytoplasmic aggregation of RPB1, the aggregation-prone largest subunit of RNA polymerase II, in biopsy samples taken from patients with invasive carcinoma of no special type. RPB1 frequently aggregates co-translationally in the absence of proper HSP90 chaperone function or in ribosome mutant cells as revealed formerly in yeast. We found that cytoplasmic foci of RPB1 occur in larger sizes in tumors that showed no regression after therapy. Based on these results, we propose that monitoring the cytoplasmic aggregation of RPB1 may be suitable for determining-from biopsy samples taken before treatment-the effectiveness of neoadjuvant chemotherapy.

Surgical outcome of percutaneous transhepatic gallbladder drainage in acute cholecystitis: Ten years' experience at a tertiary care centre.

BACKGROUND: Percutaneous transhepatic gallbladder drainage (PTGBD) plays an important role in the treatment of elderly patients and/or patients in poor health with acute cholecystitis (AC). The primary aim of this study is to determine how these factors influence the clinical outcome of PTGBD. Moreover, we assessed the timing and results of subsequent cholecystectomies. PATIENTS AND METHODS: We retrospectively examined the results of 162 patients undergoing PTGBD between 2010 and 2020 (male-female ratio: 51.23% vs. 48.77%; mean age: 71.43 ± 13.22 years). Patient's performance status and intervention outcomes were assessed with clinical success rates (CSR) and in-hospital mortality. The conversion rate (CR) of possible urgent or delayed, elective laparoscopic cholecystectomies (LC) after PTGBD were analysed. RESULTS: PTGBD was the definitive treatment in 42.18% of patients, while it was a bridging therapy prior to cholecystectomy (CCY) for the other patients. CSR was 87.97%, it was only 64.29% in grade III AC. In 9.87% of the cases, urgent LC was necessary after PTGBD, and its conversion rate was approximately equal to that of elective LC (18.18 vs. 17.46%, respectively, p = 0.2217). Overall, the post-PTGBD in-hospital mortality was 11.72%, while the same figure was 0% for grade I AC, 7.41% for grade II and 40.91% for grade III. Based on logistic regression analyses, in-hospital mortality (OR 6.07; CI 1.79-20.56), clinical progression (OR 7.62; CI 2.64-22.05) and the need for emergency CCY (OR 14.75; CI 3.07-70.81) were mostly determined by AC severity grade. CONCLUSION: PTGBD is an easy-to-perform intervention with promising clinical success rates in the treatment of acute cholecystitis. After PTGBD, the level of gallbladder inflammation played a decisive role in the course of AC. In a severe, grade III inflammation, we have to consider low CSR and high mortality.

Complete laparoscopic-transhiatal removal of duplex benign oesophageal tumour: case report and review of literature.

BACKGROUND: Leiomyoma is the most common benign oesophageal tumour. Half of all leiomyoma patients have oesophagus-associated complaints, such as dysphagia and epigastric pain, and the other 50% are asymptomatic with a diagnosis made on incidental discovery. Endoscopic ultrasonography is essential for an accurate preoperative workup and can enable guided-tissue acquisition for immunohistochemistry in certain cases. Smaller tumours are amenable to traditional and novel endoscopic removal in specialized centres, but some complex cases require surgical enucleation with a minimally invasive approach. CASE PRESENTATION: An asymptomatic 60-year-old woman was accidentally diagnosed with a bifocal oesophageal mass, which was discovered by chest computed tomography. We report a rare case of a duplicated lower-third oesophageal leiomyoma, which was completely removed via the laparoscopic transhiatal approach. The patient has recovered successfully from the surgery. She has been followed up for six months with a normal oesophagram, adequate oesophageal function and no complaints observed. Pathological examination confirmed the diagnosis of leiomyoma in both lesions. CONCLUSIONS: To the best of our knowledge, this is the first reported case of duplex oesophageal leiomyomas removed laparoscopically. Using the minimally invasive abdominal technique, the lower oesophagus can be mobilised to the mediastinum without pleura injury and offers a good alternative to the thoracoscopic approach in patients with possible intrathoracic difficulties. At experienced centres, laparoscopic transhiatal enucleation of lower oesophageal leiomyomas and other benign tumours with a combination of intraoperative oesophagoscopy is a safe, fast and effective operation.

Evaluation of the conversion rate as it relates to preoperative risk factors and surgeon experience: a retrospective study of 4013 patients undergoing elective laparoscopic cholecystectomy.

BACKGROUND: Our aim is to determine the relationships among patient demographics, patient history, surgical experience, and conversion rate (CR) during elective laparoscopic cholecystectomies (LCs). METHODS: We analyzed data from patients who underwent LC surgery between 2005 and 2014 based on patient charts and electronic documentation. CR (%) was evaluated in 4013 patients who underwent elective LC surgery. The relationships between certain predictive factors (patient demographics, endoscopic retrograde cholangiopancreatography (ERCP), acute cholecystitis (AC), abdominal surgery in the patient history, as well as surgical experience) and CR were examined by univariate analysis and logistic regression. RESULTS: In our sample (N = 4013), the CR was 4.2%. The CR was twice as frequent among males than among females (6.8 vs. 3.2%, p < 0.001), and the chance of conversion increased from 3.4 to 5.9% in patients older than 65 years. The detected CR was 8.8% in a group of patients who underwent previous ERCP (8.8 vs. 3.5%, p < 0.001). From the ERCP indications, most often, conversion was performed because of severe biliary tract obstruction (CR: 9.3%). LC had to be converted to open surgery after upper and lower abdominal surgeries in 18.8 and 4.8% cases, respectively. Both AC and ERCP in the patient history raised the CR (12.3%, p < 0.001 and 8.8%, p < 0.001). More surgical experience and high surgery volume were not associated with a lower CR prevalence. CONCLUSIONS: Patient demographics (male gender and age > 65 years), previous ERCP, and upper abdominal surgery or history of AC affected the likelihood of conversion. More surgical experience and high surgery volume were not associated with a lower CR prevalence.

Incarcerated gallbladder in inguinal hernia: a case report and literature review.

BACKGROUND: Treating hernias is one of the oldest challenges in surgery. The gallbladder as content in the case of abdominal hernias has only been reported in a few cases in the current literature. Cholecyst has only been described in the content of an inguinofemoral hernia in one case to date. CASE PRESENTATION: A 73-year-old female patient was admitted to the Emergency Department due to complaints in the right inguinal area, which had started 1 day earlier. The patient complained of cramp-like abdominal pain and nausea. Physical examination confirmed an apple-sized, irreducible hernia in the right inguinal region. Abdominal ultrasound confirmed an oedematous intestinal loop in a 70-mm-long hernial sac, with no circulation detected. Abdominal X-ray showed no signs of passage disorder. White blood cell count and C-reactive protein level were elevated, and hepatic enzymes were normal in the laboratory findings. Exploration was performed via an inguinal incision on the right side, an uncertain cystic structure was found in the hernial sac, and several small abnormal masses were palpated there. The abdominal cavity was explored from the middle midline laparotomy. During the exploration, the content of the hernial sac was found to be the fundus of the significantly ptotic, large gallbladder. Cholecystectomy and Bassini's repair of the inguinal hernia were performed safely. CONCLUSIONS: Following a review of the literature, it can be concluded that the finding of incarcerated gallbladder in the content of an inguinal hernia is a rare finding. No other similar emergency case and successful surgical intervention have been reported before.

Laparoscopic transperitoneal and retroperitoneal adrenalectomy: a 20-year, single-institution experience with an analysis of the learning curve and tumor size [lap transper and retroper adrenalectomy].

BACKGROUND: The superiority of laparoscopic transperitoneal (TP) versus retroperitoneal (RP) adrenalectomy is an ongoing debate. METHODS: Data from 163 patients (TP: n = 135; RP: n = 28) undergoing minimally invasive adrenalectomy were analyzed. Both operative [intraoperative blood loss, previous abdominal surgery, conversion rate, operative time and tumor size] and perioperative [BMI (body mass index), ASA (American Society of Anesthesiologists) score, time of hospitalization, time of oral intake, histology and postoperative complications] parameters were compared. Both the learning curve (LC) and tumor size were analyzed. RESULTS: We found significant differences in the mean operative time (p = 0.019) and rate of previous abdominal surgery (p = 0.038) in favor of TP. Significantly larger tumors were removed with TP (p = 0.018). Conversion rates showed no significant difference (p = 0.257). Also, no significant differences were noted for time of hospitalization, intraoperative blood loss and postoperative complications. In terms of the LC, we saw significant differences in previous abdominal surgery (p = 0.015), conversion rate (p = 0.011) and operative time (p = 0.023) in favor of TP. Large (LT) and extra-large tumors (ELT) were involved in 47 lesions (LT: 40 vs. ELT: 7), with a mean tumor size of 71.85 and 141.57 mm, respectively. Mean intraoperative blood loss was 64.47 ml vs. 71.85 ml, time of hospitalization was 5.10 vs. 4.57 days and mean operative time was 76.52 vs. 79.28 min for LT and ELT, respectively. CONCLUSION: A shorter operative time and lower conversion rate in favor of TP were noted during the learning curve. TP proved to be more effective in the removal of large-, extra-large and malignant lesions. The RP approach was feasible for smaller, benign lesions, with a more prolonged learning curve.

Evaluating the distribution of the locations of colorectal cancer after appendectomy and cholecystectomy.

BACKGROUNDS: The number of appendectomies and cholecystectomies performed is gradually increasing worldwide. An increasing incidence of colorectal cancer (CRC) after appendectomy and cholecystectomy has been reported, but the location of tumors in certain segments of the colon and rectum after appendectomy and cholecystectomy is still uncertain. We aimed to evaluate the distribution of the locations of colorectal cancer after appendectomy and/or cholecystectomy in patients who underwent CRC surgery. METHODS: We reviewed the medical records of patients who had undergone CRC surgery between 2015 and 2017 for the presence of previous appendectomy/cholecystectomy. Data were collected from the Colorectal Data Base of the University of Szeged, Department of Surgery. RESULTS: Surgery for CRC was performed in 640 patients during the study period. Data of 604 patients were analyzed. Appendectomy was performed in 100 patients (16.6%), cholecystectomy in 65 (10.8%), and both interventions in 18 (3%) before the CRC surgery. Out of those patients who underwent appendectomy alone, 92 (92%) had undergone appendectomy more than 10 years before the CRC surgery. Also in these 100 patients, the prevalence of right-sided colon cancer (CC) was 35% (n = 35), in comparison with the prevalence among the 504 other patients (20.4%, n = 103). The prevalence of right-sided CC among patients who underwent cholecystectomy alone was 36.9% (n = 24), in comparison with 21.2% (n = 114) of the 539 other patients. CONCLUSIONS: A significant left to right side shift in CRC was noted among patients who had previously undergone appendectomy/cholecystectomy. Because right-sided CC has a worse prognosis, the role of incidental appendectomy and routine cholecystectomy seems that need re-evaluation.

What contributes to long-term quality of life in breast cancer patients who are undergoing surgery? Results of a multidimensional study.

PURPOSE: This study aims to examine the key determinants of long-term quality of life in breast cancer patients who are undergoing surgery using a multidimensional approach and taking into account preoperative and post-operative psychological characteristics such as anxiety, depression, posttraumatic growth, body image, and physical activity as well as medical parameters. METHODS: The study involved 63 breast cancer patients from the Department of Surgery at the University of Szeged. Assessments occurred 1 day before surgery as well as 3 days and 18 months after surgery using the Spielberger State and Trait Anxiety Inventory (STAI), Beck's Depression Inventory (BDI), Functional Assessment of Cancer Therapy-Breast Cancer Scale (FACT-B), Posttraumatic Growth Inventory (PTGI) and Breast Impact of Treatment Scale (BITS). Data relating to physical activity, medical parameters and sociodemographic characteristics were also collected. RESULTS: The level of depression did not change over time. State anxiety decreased 18 months after the surgery compared to before the surgery; however, there was a greater decrease immediately after the surgery and then anxiety increased again 18 months later. Trait anxiety was associated with quality of life, posttraumatic growth and body image. Posttraumatic growth and the level of depression were found to be possible contributing factors to the increase in long-term quality of life. CONCLUSIONS: The results show that the timely detection and proper management of psychological distress and the enhancement of posttraumatic growth are of great value, as they might be important contributing factors to long-term quality of life in breast cancer patients.

[Removal of giant adrenal tumors using the laparoscopic transperitoneal technique. A report of three successful cases]. / Óriás mellékvesetumorok eltávolítása laparoszkópos transperitonealis technikával három sikeres eset kapcsán.

With the development of laparoscopic adrenalectomy, indications for resection gradually span from small and benign to bigger and even malignant lesions. We studied the results of laparoscopic adrenalectomy for giant (>10 cm) adrenal tumors in three cases. Three patients (2 female, 1 male, mean age 49.33 years, BMI 31) underwent laparoscopic transperitoneal adrenalectomy due to giant (>10 cm) adrenal lesions with a limited size Pfannenstiel incision. Mean operative time was 126.66 minutes, with a mean intraoperative blood loss of 150 ml. Final histology confirmed adrenocortical carcinoma in two cases, and neurofibroma in one case. Mean hospital stay was 4 days, without perioperative complications. R0 resection was carried out in all cases. During a mean follow-up period of 24 months no local or distant metastasis occurred. Under appropriate conditions adrenalectomy performed by the laparoscopic transperitoneal technique for giant malignant tumors proved to be a safe method fulfilling oncological requirements.

[Tension-type headache in ulcerative colitis]. / Tenziós típusú fejfájás és colitis ulcerosa.

BACKGROUND AND PURPOSE: Tension-type headache is a very common disease with a high socio-economic impact as its lifetime prevalence is 30-78% in the general population. The incidence of inflammatory bowel diseases is continuously rising. Limited data are accessible on quality of life in patients with surgically treated ulcerative colitis. The aim of our study is to examine quality of life, concerning headache, among patients who had undergone surgery due to ulcerative colitis. METHODS: Between 1 January 2005 and 1 March 2016, surgery was performed due to ulcerative colitis in 75 patients. During this retrospective analysis the average duration of the follow-up was 46 (1-124) months. The pre-sence of headache was evaluated by the use of Brief Illness Perception and Headache Questionnaires. RESULTS: Among the primary headache disorders (n=27), tension-type headache occurred in 19 (70.4%) cases, and 8 (29.6%) patients had migraine (without aura). Among tension-type headache cases 17 (89.5%) patients experienced episodic form and 2 (10.5%) suffered from chronic form. Patients with headache had obtained a significantly higher score on Brief Illness Perception Questionnaire. CONCLUSION: According to our study tension-type headache is common among patients with ulcerative colitis. This observation raises the question whether stress plays role in the pathogenesis of both diseases, which influences and worsens considerably quality of life. Neurological examination, psychological and psychiatric guidance are worth considering in patients with ulcerative colitis.

[Laparoscopic removal of large spleens: Pfannenstiel incision as an alternative specimen extraction method]. / Laparoscopos technika alkalmazása nagyméretu lépek eltávolítására: Pfannenstiel-metszés mint alternatív specimeneltávolítási mód.

BACKGROUND: Removing the extremely enlarged spleen from the abdominal cavity is a common technical problem in case of laparoscopic splenectomy ( LS). In general, the specimen is placed into a plastic bag and removed after morcellation. In case of massive splenomegaly , when the spleen weight is 1000-2000 grams, this method is often not feasible, because the spleen size is larger than the maximum capacity of the EndoBag. According to the literature in this case the splenic extraction was performed by specimen fragmentation in the abdominal cavity (risk of splenosis) or by a laparotomy. To solve this problem our team removes the specimen via a Pfannenstiel incision since 2009. METHODS: Between January 1, 2002 and September 30, 2014, 74 LS procedures were performed at our department. The specimen was retrieved with morcellation in a conventional manner through the lateral port site in 56 cases, whereas in 12 cases, the large spleen was retrieved through a 10-12 cm long Pfannenstiel incision. RESULTS: The mean duration of surgery was 121 (50-220) minutes. In those cases where the specimen was retrieved through a Pfannenstiel incision the mean duration of surgery was significantly shorter (108 vs. 125 minutes; p=0.05), and the mean spleen size was significantly larger (1032 vs. 338 grams; p=0.0001) than in the case of morcellation. In the duration of the mean postoperative hospital stay there was no significant difference (4.7 vs. 5.2 days; p=0.178). CONCLUSION: Our study supports that laparoscopic splenectomy is safe and has numerous advantages even in the case of massive splenomegaly. The retrieval of the specimen through a Pfannenstiel incision is considered a safe and cosmetically acceptable alternative.

[Modern surgical treatment of breast cancer. 3rd Breast Cancer Consensus Conference]. / Az emlorák korszeru sebészi kezelése. III. Emlorák-konszenzuskonferencia.

Therapy for breast cancer today is characterised by ever more precise diagnostic methods and ever more effective oncological treatments, a trend which will certainly continue into the future. Breast preservation and the application of oncoplastic principles are increasingly popular. A sentinel lymph node biopsy in the surgical treatment of the axilla is primary, with the indication for axillary block dissection (ABD) narrowing and radiation therapy becoming an alternative to ABD in certain cases. This publication summarises our recommendations on the surgical treatment of breast cancer based on the content of the 3rd Breast Cancer Consensus Conference and considering the latest international studies and professional recommendations.

Role of laparoscopic surgery in the treatment of ulcerative colitis; short- and mid-term results.

OBJECTIVES: Laparoscopy is used more widely for the surgery of ulcerative colitis. The objective of this study was a comparison of the surgical and 3-year follow-up results of patients treated with conventional and minimally invasive methods. MATERIALS AND METHODS: A total of 45 patients received surgery for ulcerative colitis, 16 as emergency and 29 as elective cases. Laparoscopy was used in 23 and a conventional method in 22 cases. No difference was found between the two groups from the aspects of American Society of Anesthesiologists physical status (ASA) class, mean body mass index (BMI) and age. There were 4 emergency cases in the laparoscopy group, and 12 in the open group. Nineteen elective surgeries were performed in the laparoscopy group, and 10 in the open group. RESULTS: There was no significant difference between the groups as concerns the length of hospital or intensive care unit (ICU) stay, the time to bowel function recovery, but the duration of open surgery was significantly shorter. There was no difference between the groups in the rate of early postoperative complications, whereas among potential late complications, the rates of intestinal obstruction (8.7% vs. 45%) and a septic condition (0% vs. 27%) were significantly lower in the laparoscopy group. There was a significant improvement in the quality of life after surgery in both groups, and better cosmetic results were observed in the laparoscopy group. CONCLUSION: Laparoscopy can be used for ulcerative colitis both emergency and elective cases, it provides a good quality of life and the mid-term rate of complications is lower as compared with open surgery.

[Minimally invasive surgical treatment of ulcerative colitis--long-term results]. / Colitis ulcerosa minimálisan invazív sebészi kezelése--hosszú távú eredmények.

INTRODUCTION: For the surgical treatment of ulcerative colitis, laparoscopy is used more widely, but less data are available on long-term results in Hungary. AIM: The aim of the authors was to compare the mean 47.8-month follow-up results of patients treated with conventional and minimally invasive surgical methods. METHOD: Between January 1, 2005 and December 31, 2014, 56 patients were treated with surgery (20 emergencies, and 36 elective cases). Laparoscopy was used in 33 and conventional method in 23 cases. RESULTS: There was no difference between the two groups in hospital and intensive care unit stay, bowel function recovery, need for transfusion, and complications during the perioperative period. Regarding long-term complications, the occurrence of intestinal obstruction, septic condition and other complications were significantly fewer in the laparoscopy group. The quality of life improved in both groups after the surgery. CONCLUSIONS: Laparoscopy can be used safely; it provides good quality of life and better cosmetic results, and the long-term rate of complications is lower as compared to open surgery.

[Treatment of pregnancy-associated breast cancer]. / A terhességgel összefüggo emlodaganatok kezelése.

CASE REPORT: A 25-year-old primipara, in the thirty-second week of her pregnancy observed a nodule in the upper outer quadrant of her left breast during self-examination. Complex breast examination revealed calcification with 4 cm of diameter. Ductal malignant cells (C5) were identified by fine-needle aspiration biopsy, while core biopsy verified invasive ductal carcinoma, grade III (B5b). No manifestations of metastases were presented. After pregnancy termination wide excision with additional axillary sentinel lymph node biopsy was performed. Because of its positivity block dissection of axillary lymph nodes was carried out. The surgical therapy was followed by adjuvant chemo-, radio- and hormonal therapy. Later an angiomyxoma appeared in the right inguinal region, which was excised in toto. DISCUSSION: The incidence of pregnancy related malignant diseases is increasing, of which breast cancer predominates. Breast cancer, which is diagnosed during pregnancy or within the first year of delivery is called pregnancy-associated breast cancer. Because of the physiological changes in pregnancy the recognition of the disease is difficult. Therapy is complex, as besides the treatment of the mother, the safety of the fetus should be emphasized. The treatment strategies are different in the three trimesters. The surgical treatment can be performed during the whole pregnancy. The use of radiotherapy is controversial, because of teratogenic effects, while chemotherapy is permitted in the second and third trimesters. Nearly three years after the operation, our patient does not have any symptoms, her son is healthy.

[Comparison of surgical patients with gastroesophageal reflux disease and Barrett's esophagus]. / Refluxbetegség és Barrett-nyelocso miatt mutétre kerülo betegek összehasonlító vizsgálata.

INTRODUCTION: Barrett's esophagus (BE) is the only known precursor of adenocarcinoma occuring in the lower third of the esophagus. According to statistics, severity and elapsed time of gastroesophageal reflux disease (GERD) are major pathogenetic factors in the development of Barrett's esophagus. PATIENTS AND METHODS: In a retrospective study between 2001 and 2008, we compared the preoperative results (signs and sympthoms, 24 hour pH manometry, esophageal manometry, Bilitec) and treatment efficacy of 176 GERD patients and 78 BE patients, who have undergone laparoscopic Nissen procedure for reflux disease. RESULTS: The two groups of patients had similar demographic features, and elapsed time of reflux sympthoms were also equal. Both groups were admitted for surgery after a median time of 1.5 years (19.87 vs. 19.20 months) of ineffective medical (proton pump inhibitors) treatment. Preoperative functional tests showed a more severe presence of acid reflux in the BE group (DeMeester score 18.9 versus 41.9, p < 0.001). On the other hand, mano-metry - despite confirming lower esophageal sphincter (LES) damage - did not show difference between the two groups (12.10 vs. 12.57 mmHg, p = 0.892). We did not experience any mortality cases with laparoscopic antireflux procedures, although in two cases we had to convert during the operation (1 due to extensive adhesions, and 1 due to injury to the spleen). 3 months after the procedure - according to Visick score - both groups experienced a significant decrease, or lapse in reflux complaints (group I: 73%, group II: 81% of patients), LES functions improved (17.58 vs.18.70 mmHg), and the frequency and exposition of acid reflux decreased (DeMeester score 7.73 vs. 12.72). CONCLUSION: The severity of abnormal acid reflux occuring parallel with the incompetent function of the damaged LES triggers not only inflammation in the gastroesophageal junction (GEJ), but also metaplastic process, and the development of Barrett's esophagus. Laparoscopic Nissen procedure for reflux disease can further improve outcome among patients with GERD not responding to conservative therapy.

[Comparison of laparoscopic and open splenectomy]. / Laparoscopos és nyitott splenectomia összehasonlítása.

INTRODUCTION: Conventional operative techniques are gradually being replaced by minimally invasive surgical methods in the surgery of the spleen. We summarized our 10-year-experience after the introduction of laparoscopic splenectomy at the University of Szeged, Department of Surgery, comparing open and minimally invasive techniques. MATERIAL AND METHOD: Between 1st January 2002 and 1st December 2011 we performed 141 splenectomies of which 17 were acute operations. Of the 124 elective procedures 54 were laparoscopic and 70 open operations. In 40 cases (open procedures) splenectomy was part of multivisceral surgery which were excluded from the analysis. In this retrospective analysis a comparison of laparoscopic and open elective technique was carried out. RESULTS: Average operating time of laparoscopic procedures was slightly longer than that of open technique (133 vs. 122 minutes, p = 0.074). After the learning period, duration of laparoscopic procedures became shorter (first five years: 147 min., second five years: 118 min, p = 0.003), larger spleens were removed (220 vs. 450 grams, p = 0.063) and conversion rate became lower. In cases of laparoscopic procedures fewer reoperations needed to be performed (1.5% vs. 6%, p = 0.718), bowel motility recovered earlier (2 vs. 3 days, p = 0.002) and hospital stay was shorter (5 vs. 8 days, p ≤ 0.001). CONCLUSION: Our study proves that laparoscopic splenectomy is a safe method with many advantages. Our results correlate with data of international publications.

Impact of neoadjuvant FLOT treatment of advanced gastric and gastroesophageal junction cancer following surgical therapy.

Introduction: Therapeutic treatment for advanced-stage (T2-T4) gastroesophageal junction (GEJ) and gastric cancer involves neoadjuvant chemotherapy with subsequent surgical intervention. Method: Neoadjuvant oncological treatment for GEJ and gastric cancer previously consisted of the intravenous administration of epirubicin, cisplatin and fluorouracil (ECF) or epirubicin, cisplatin and capecitabine (ECX) combination (Group 1). The new protocol (FLOT, F: 5-FU, L: leucovorin, O: oxaliplatin, T: docetaxel), included patients with resectable GEJ and gastric cancer who had a clinical stage cT2 or higher nodal positive cN+ disease (Group 2). Between 31 December 2008 and 31 October 2022, the effect of different oncological protocols in terms of surgical outcomes in cases of T2-T4 tumours were retrospectively evaluated. Results of randomly assigned patients from the earlier ECF/ECX protocol (n = 36) (Group 1) and the new FLOT protocol (n = 52) (Group 2) were compared. Effect of different neoadjuvant therapies on tumour regression, types of possible side effects, type of surgery, and oncological radicality of surgical procedures were analysed. Results: When comparing the two groups, we found that in case of the FLOT neoadjuvant chemotherapy (Group 2, n = 52), complete regression was achieved in 13.95% of patients, whereas in the case of ECF/ECX (Group 1, n = 36), complete regression occurred in only 9.10% of patients. Furthermore, in the FLOT group, the mean number of lymph nodes removed was slightly higher (24.69 vs. 20.13 in the ECF/ECX group). In terms of the safety resection margin (proximal), no significant difference was found between the two treatment groups. Nausea and vomiting were the most common side effects. The occurrence of diarrhea was significantly higher in the FLOT group (p = 0.006). Leukopenia and nausea occurred more commonly with the old protocol (Group 1). The rate of neutropenia was lower following FLOT treatment (p = 0.294), with the lack of grade II and III cases. Anaemia occured at a significantly higher rate (p = 0.036) after the ECF/ECX protocol. Conclusions: As a result of the FLOT neoadjuvant oncological protocol for advanced gastro-esophageal junction and gastric cancer, the rate of complete tumour regression increased significantly. The rate of side effects was also appreciably lower following the FLOT protocol. These results strongly suggest a significant advantage of the FLOT neoadjuvant treatment used before surgery.

The effects of laparoscopic Nissen fundoplication on Barrett's esophagus: long-term results.

OBJECTIVE: The aim of our study was to conduct a retrospective investigation of the efficacy of laparoscopic Nissen fundoplication in patients with Barrett's esophagus. MATERIAL AND METHODS: A total of 78 patients with Barrett's esophagus underwent surgery. Patients were divided into three groups on the basis of the preoperative endoscopic biopsies: a non-intestinal group (n = 63) with fundic or cardiac metaplasia, an intestinal group (n = 18) with intestinal metaplasia, and a dysplastic group (n = 7) with low-grade dysplasia. Clinical follow-up was available in the case of 64 patients at a mean of 42 ± 16.9 months after surgery. RESULTS: Check-up examination revealed total regression of Barrett's metaplasia in 10 patients. Partial regression was seen in 9 cases, no further progression in 34 patients, and progression into cardiac or intestinal metaplasia in 11 patients. No cases of dysplastic or malignant transformation were registered. Where we observed the regression of BE, among the postoperative functional examinations results of manometry (pressure of lower esophageal sphincter) and pH-metry were significantly better compared with those groups where no changes occurred in BE, or progression of BE was found. Discussion. Our results highlight the importance of the cases of fundic and cardiac metaplasia, which can also transform into intestinal metaplasia. CONCLUSIONS: Antireflux surgery can appropriately control the reflux disease in a majority of the patients who had unsuccessful medical treatment, and it may inhibit the progression and induce the regression of Barrett's metaplasia in a significant proportion of these patients.
