RESUMO

Background and purpose:

Although headaches are often comorbid with psychological symptoms, the underlying psychological processes, e.g. the role of personality dimensions as headache determinants remains unclear. Studies found associations between headaches and various personality traits; according to the Big Five model of personality, persons suffering from headaches exhibit a higher rate in neuroticism, while a lower rate in extraversion, openness to experiences and positive emotions. This is the first study to clarify the associations among duration, intensity, and frequency of headaches and personality dimensions. Through this study we could get into the personality dimensions in the background of pain experience and that which personality dimensions bear a part in the behaviour of the persons, who suffered from headache, but do not seek treatment through this complaint. 

. Methods:

Treated (Group1) and untreated (Group2) headache patients and healthy controls (Group3) were investigated (total of 360 participants). The main headache components of intensity, duration, and frequency were used as dependent variables with personality dimensions in the Big Five concept investigated by the NEO-PI-R Personality Inventory.

. Results:

Employing multiple regression analysis, facets of personality described 14.7% of headache intensity, 10.9 % of duration, and 18.7 % of frequency variance. Group1 and Group2 reached significantly higher values on the dimension of anxiety, depression, and vulnerability to stress than Group3. Group1 showed a significantly higher value on trust personality dimension than Group3 and Group2. Group3 exhibited a significantly higher value in the trust dimension than Group2. Concerning vulnerability to stress, the highest value was yielded by the “treated and suffering from headaches” group and there was a significant difference also with the “untreated and suffering from headaches” group and with the control group. In this dimension, the “untreated and suffering from headaches” group’s point value was significantly higher than the control group’s (p<0.01, U=-4.501).

. Conclusion:

Our study demonstrates that the three headache components are not independent from personality traits, and personality traits may interact with treatment seeking behavior even in the presence of significant headache complaints. The role of the personality traits are significant in the intensity, duration and frequency of headaches.

RESUMO

Migraine is a neurovascular disorder that can be debilitating for individuals and society. Current research focuses on finding effective analgesics and management strategies for migraines by targeting specific receptors and neuropeptides. Nonetheless, newly approved calcitonin gene-related peptide (CGRP) monoclonal antibodies (mAbs) have a 50% responder rate ranging from 27 to 71.0%, whereas CGRP receptor inhibitors have a 50% responder rate ranging from 56 to 71%. To address the need for novel therapeutic targets, researchers are exploring the potential of another secretin family peptide, pituitary adenylate cyclase-activating polypeptide (PACAP), as a ground-breaking treatment avenue for migraine. Preclinical models have revealed how PACAP affects the trigeminal system, which is implicated in headache disorders. Clinical studies have demonstrated the significance of PACAP in migraine pathophysiology; however, a few clinical trials remain inconclusive: the pituitary adenylate cyclase-activating peptide 1 receptor mAb, AMG 301 showed no benefit for migraine prevention, while the PACAP ligand mAb, Lu AG09222 significantly reduced the number of monthly migraine days over placebo in a phase 2 clinical trial. Meanwhile, another secretin family peptide vasoactive intestinal peptide (VIP) is gaining interest as a potential new target. In light of recent advances in PACAP research, we emphasize the potential of PACAP as a promising target for migraine treatment, highlighting the significance of exploring PACAP as a member of the antimigraine armamentarium, especially for patients who do not respond to or contraindicated to anti-CGRP therapies. By updating our knowledge of PACAP and its unique contribution to migraine pathophysiology, we can pave the way for reinforcing PACAP and other secretin peptides, including VIP, as a novel treatment option for migraines.

RESUMO

We report the case of a 42-year-old woman with paraparesis associated with transverse myelitis. For differential diagnostics detailed microbiological, cerebrospinal fluid (CSF) and neuroimaging examinations were performed. Syphilis was confirmed, but diagnosis of neurosyphilis was only probable based on the CSF microbiological test results. The beneficial treatment response to application of the therapeutic protocol for syphilis supported the supposed diagnosis of syphilis-associated myelitis in our case. In this case report we reviewed the differential diagnostic tools of myelopathies/myelitis.
Nowadays regarding to growing prevalence of syphilis worldwide physicians should face on its presence and medical consequences.

RESUMO

Migraine as a common primary headache disorder has a significant negative effect on quality of life of the patients. Its pharmacotreatment includes acute and preventative therapies. Based on the shared therapeutic guideline of the European Headache Federation and the European Academy of Neurology for acute migraine treatment a combination of triptans and non-steroidal anti-inflammatory drugs is recommended for acute migraine treatment in triptan-nonresponders. In this short review we summarized the results of the randomized controlled clinical trials evaluating the effectiveness and safety of sumatriptan (85 mg)/naproxen sodium (500 mg) fix-dose combination. It was revealed that the fix-dose combination was better than placebo for the primary outcomes of exemption of pain and headache relief at 2 hours. Furthermore the combination showed beneficial effect on accompanying symptoms of migraine attack (i.e. nausea, photo- and phonophobia). Adverse events were mild or moderate in severity and rarely led to withdrawal of the drug.
It can be concluded that sumatriptan (85 mg)/naproxen sodium (500 mg) fix-dose combination is effective, safe and well-tolerated in the acute treatment of migraine.

RESUMO

Background and purpose:

Using patient registries is essential both in clinical research and in medical practice. Headaches, more specifically migraines are one of the most common complaints that can detract the quality of a patient’s life and these complaints also have a significant socio-econo­mic effect. Our goal is to create a national Headache Registry and to also provide the pre-analysis of the registry’s database.

. Methods:

Our research is based on the national Multiple Sclerosis Registry, which we modified using the latest version of diagnostic criteria published by the International Headache Society. This clinical study contains data collected from patients suffering from migraines and currently receiving care at the Headache Outpatient Department at the Neurologic Clinic of the University of Szeged.

. Results:

The data of 412 patients (363 wo­men and 49 men) suffering from migraine (migraine without aura: n = 313 and migraine with aura: n = 99) were added to the Headache Registry. The average age of participants was 44.1 ± 12.5 SD years. Regarding the attributes of migraine headaches we examined the following characteristics: localization, quality and intensity (based on the Visual Analogue Scale) of the pain, frequency (the number of headache days per month), medications (acute or prophylactic), comorbidities (depression, anxiety, hypertension, asthma, epilepsy and others), family history and the occurrence of stroke among patients.

. Conclusion:

Based on international expe­rience, patient registries are the most optimal systems for structured patient mo­nitoring. For high level management and long-term follow up of the patients the application of registries is essential. The registries include the detailed medical history and the diagnostic and therapeutic data of the patients, and they trace the changes during the follow up medical visits. Registries are able to record the entire course of the disease in digital way. The numerous data can be set out any time from the digital database. Extensive spread of patients’ registries is fundamental not only in every day clinical practice, but also in clinical research.

RESUMO

INTRODUCTION: The small molecule non-peptide calcitonin gene-related peptide (CGRP) receptor antagonists named gepants offer a breakthrough novel approach in migraine acute and prophylactic drug treatment. This review aimed to determine the place of gepants in the treatment of episodic and chronic migraine. AREAS COVERED: The new generation gepants are ubrogepant, atogepant, rimegepant, and zavegepant. Ubrogepant is ratified for acute migraine treatment, atogepant is validated for preventive therapy, whereas rimegepant is ratified for both indications, all via oral administration and while zavegepant is administered intranasally for migraine attacks. Gepants are effective, safe, and well-tolerated in acute or prophylactic therapy. The PubMed literature search included randomized controlled trials, meta-analyses, real-world data, and review articles published in English until January 2023. EXPERT OPINION: Whether gepants will be real game changers in the acute treatment of migraine compared to triptans and ditans or in the prophylactic therapy compared to standard-of-care preventive drugs or CGRP-targeting monoclonal antibodies cannot be answered yet based on the available literature data.

RESUMO

BACKGROUND: The glutamatergic neurotransmission has important role in the pathomechanism of primary headache disorders. The kynurenine metabolites derived from catabolism of tryptophan (Trp) have significant involvement not only in glutamatergic processes, but also in the neuroinflammation, the oxidative stress and the mitochondrial dysfunctions. Previously we identified a depressed peripheral Trp metabolism in interictal period of episodic migraineurs, which prompted us to examine this pathway in patients with episodic cluster headache (CH) as well. Our aims were to compare the concentrations of compounds both in headache-free and attack periods, and to find correlations between Trp metabolism and the clinical features of CH. Levels of 11 molecules were determined in peripheral blood plasma of healthy controls (n = 22) and interbout/ictal periods of CH patients (n = 24) by neurochemical measurements. FINDINGS: Significantly decreased L-kynurenine (KYN, p < 0.01), while increased quinolinic acid (QUINA, p < 0.005) plasma concentrations were detected in the interbout period of CH patients compared to healthy subjects. The levels of KYN are further reduced during the ictal period compared to the controls (p < 0.006). There was a moderate, negative correlation between disease duration and interbout QUINA levels (p < 0.048, R = - 0.459); and between the total number of CH attacks experienced during the lifetime of patients and the interbout KYN concentrations (p < 0.024, R = - 0.516). Linear regression models revealed negative associations between age and levels of Trp, kynurenic acid, 3-hdyroxyanthranilic acid and QUINA in healthy control subjects, as well as between age and ictal level of anthranilic acid. CONCLUSIONS: Our results refer to a specifically altered Trp metabolism in CH patients. The onset of metabolic imbalance can be attributed to the interbout period, where the decreased KYN level is unable to perform its protective functions, while the concentration of QUINA, as a toxic compound, increases. These processes can trigger CH attacks, which may be associated with glutamate excess induced neurotoxicity, neuroinflammation and oxidative stress. Further studies are needed to elucidate the exact functions of these molecular alterations that can contribute to identify new, potential biomarkers in the therapy of CH.

RESUMO

Chronic pain conditions have a high socio-economic impact and represent a burden for patients, and their management is a challenge for healthcare professionals. Chronic migraine is one of the chronic primary headache disorders, which belong to chronic primary pain syndromes as per the new concept of multiple parenting. The aims of this review were to provide an overview of the latest classification systems involving both entities, the epidemiological data, and the currently recommended prophylactic treatment options for chronic migraine. Randomized controlled clinical trials, meta-analyses, real-world data, and review articles were analyzed. Chronic migraine is a prevalent and highly burdensome disease and is associated with high headache-related disability and worsening health-related quality of life. Treatment of chronic migraine includes pharmacological or, in drug-refractory cases, non-pharmacological (e.g., neuromodulatory) approaches. Among pharmacological treatment options, injectable botulinum toxin type A and calcitonin gene-related peptide-targeting human and fully humanized monoclonal antibodies (i.e., eptinezumab, erenumab, fremanezumab, and galcanezumab) are highly recommended in the preventive treatment of chronic migraine. Novel migraine-specific therapies offer a solution for this devastating and difficult-to-treat chronic pain condition.

RESUMO

IgG4-related (IgG4-RD) disease is a relatively newly identified, chronic autoimmune disorder that can affect any organ system. The disease is relatively rare. It has mostly systemic presentation, however it can also appear in isolated form in one single organ. In our report, we demonstrate an elderly male patient's case with IgG4-RD presented in the form of diffuse meningeal inflammation and hypertrophic pachymeningitis with one-sided cranial nerve and intraventricular involvement.

RESUMO

Migraine and neuropathic pain (NP) are both painful, disabling, chronic conditions which exhibit some symptom similarities and are thus considered to share a common etiology. The calcitonin gene-related peptide (CGRP) has gained credit as a target for migraine management; nevertheless, the efficacy and the applicability of CGRP modifiers warrant the search for more effective therapeutic targets for pain management. This scoping review focuses on human studies of common pathogenic factors in migraine and NP, with reference to available preclinical evidence to explore potential novel therapeutic targets. CGRP inhibitors and monoclonal antibodies alleviate inflammation in the meninges; targeting transient receptor potential (TRP) ion channels may help prevent the release of nociceptive substances, and modifying the endocannabinoid system may open a path toward discovery of novel analgesics. There may exist a potential target in the tryptophan-kynurenine (KYN) metabolic system, which is closely linked to glutamate-induced hyperexcitability; alleviating neuroinflammation may complement a pain-relieving armamentarium, and modifying microglial excitation, which is observed in both conditions, may be a possible approach. Those are several potential analgesic targets which deserve to be explored in search of novel analgesics; however, much evidence remains missing. This review highlights the need for more studies on CGRP modifiers for subtypes, the discovery of TRP and endocannabinoid modulators, knowledge of the status of KYN metabolites, the consensus on cytokines and sampling, and biomarkers for microglial function, in search of innovative pain management methods for migraine and NP.

RESUMO

BACKGROUND: Migraine is a primary headache with genetic susceptibility, but the pathophysiological mechanisms are poorly understood, and it remains an unmet medical need. Earlier we demonstrated significant differences in the transcriptome of migraineurs' PBMCs (peripheral blood mononuclear cells), suggesting the role of neuroinflammation and mitochondrial dysfunctions. Post-transcriptional gene expression is regulated by miRNA (microRNA), a group of short non-coding RNAs that are emerging biomarkers, drug targets, or drugs. MiRNAs are emerging biomarkers and therapeutics; however, little is known about the miRNA transcriptome in migraine, and a systematic comparative analysis has not been performed so far in migraine patients. METHODS: We determined miRNA expression of migraineurs' PBMC during (ictal) and between (interictal) headaches compared to age- and sex-matched healthy volunteers. Small RNA sequencing was performed from the PBMC, and mRNA targets of miRNAs were predicted using a network theoretical approach by miRNAtarget.com™. Predicted miRNA targets were investigated by Gene Ontology enrichment analysis and validated by comparing network metrics to differentially expressed mRNA data. RESULTS: In the interictal PBMC samples 31 miRNAs were differentially expressed (DE) in comparison to healthy controls, including hsa-miR-5189-3p, hsa-miR-96-5p, hsa-miR-3613-5p, hsa-miR-99a-3p, hsa-miR-542-3p. During headache attacks, the top DE miRNAs as compared to the self-control samples in the interictal phase were hsa-miR-3202, hsa-miR-7855-5p, hsa-miR-6770-3p, hsa-miR-1538, and hsa-miR-409-5p. MiRNA-mRNA target prediction and pathway analysis indicated several mRNAs related to immune and inflammatory responses (toll-like receptor and cytokine receptor signalling), neuroinflammation and oxidative stress, also confirmed by mRNA transcriptomics. CONCLUSIONS: We provide here the first evidence for disease- and headache-specific miRNA signatures in the PBMC of migraineurs, which might help to identify novel targets for both prophylaxis and attack therapy.

RESUMO

For the centenary of the Department of Surgery, University of Szeged we have investigated and summarized the results and outcomes of 779 anti-reflux surgery cases between 1. January 2000 ­ 31. May 2021. The indication for surgery was made in close collaboration with the internal medicine workgroup depending on the results of endoscopy and functional tests. The primer indication for surgery was medical therapy-resistant reflux disease. Based on our clinical practice we performed laparoscopic Nissen fundoplication in 98,2% of the cases. Besides the long- and short-term postoperative complications, we investigated the long-term effect of anti-reflux surgery on acid and bile reflux, and the improvement of the patients' quality of life using the Visick score, and modified GERD-HRLQ score. Our investigations have proven the effect of acid and bile reflux in the pathogenesis of Barrett's esophagus and furthermore we have confirmed that laparoscopic anti-reflux surgery restores the function of the lower esophageal sphincter and eliminates acid and bile reflux, so in certain cases Barrett's esophagus regression can be achieved. But due to the heterogeneity of GERD and Barrett's esophagus long-term and regular endoscopic control is necessary.

RESUMO

Introduction. An estimated 20­30% of patients with ulcerative colitis need surgery. The generally accepted procedure for the surgical treatment is total proctocolectomy with ileal pouch-anal anastomosis. Nowadays laparoscopic technique is used more frequently. Minimally invasive surgical technique is used during the surgical treatment of colorectal diseases in the Department of Surgery in Szeged since 2005. Aim. We aimed to compare the last 16 years' results of patients treated with conventional and laparoscopic methods. Methods. Between 01. 01. 2005. and 31. 03. 2021. 99 patients (53 female, 46 male) received surgery. The laparoscopic technique was used in 74 (74.7%) and the conventional method in 25 (25.3%) cases. General status of patients, early and late results of surgical treatment, and mainly complications were analyzed. Results. There was no difference between the groups in-hospital stay, the number of days spent in the intensive care unit and the need for transfusion. During the follow-up period the time to the recovery of the bowel function, and the occurrence of late complications were significantly lower in the laparoscopically operated group of patients. Conclusions. Laparoscopic surgical treatment can be used safely for both emergency and elective cases in UC patients. The short-term perioperative results and the morbidity showed no differences between the laparoscopic and open techniques. The long-term effect of laparoscopic surgery insured a lower rate of complications.

RESUMO

BACKGROUND: Migraine is a highly prevalent primary headache with an unclear pathomechanism. During the last 40 years, numerous hypotheses have arisen; among them, the theory of the trigeminovascular system is the primary one. It serves as a skeleton in successful preclinical studies and in the development of effective therapeutic options for migraine headache. OBJECTIVE: The brain prize (awarded annually by the Lundbeck Foundation) is the most prestigious tribute in neuroscience. The winners in 2021 were Lars Edvinsson, Peter Goadsby, Michael Moskowitz and Jes Olesen. They are the fathers of migraine pathomechanism, which led to revolutionary new treatments. This review summarizes their landmark findings. METHODS: Data related to this topic were reviewed from PubMed records published between 1979 and May 2021. Searches were based on preclinical and clinical studies in the covered field. The findings were listed in chronological order. From a therapeutic perspective, only randomized controlled trials and meta-analysis were discussed. RESULTS: The calcitonin gene-related peptide-related pathogenesis of migraine is based on the activation of the trigeminovascular system. The therapeutic triad for migraine is triptans, gepants, and calcitonin gene-related peptide-targeted monoclonal antibodies. CONCLUSION: In the past 40 years, the systematic work of leading headache scientists has resulted in robust theoretical and therapeutic knowledge in the preclinical and clinical study of migraine.

RESUMO

BACKGROUND: Recent data suggest that gene expression profiles of peripheral white blood cells can reflect changes in the brain. We aimed to analyze the transcriptome of peripheral blood mononuclear cells (PBMC) and changes of plasma metabolite levels of migraineurs in a self-controlled manner during and between attacks. METHODS: Twenty-four patients with migraine were recruited and blood samples were collected in a headache-free (interictal) period and during headache (ictal) to investigate disease- and headache-specific alterations. Control samples were collected from 13 age- and sex-matched healthy volunteers. RNA was isolated from PBMCs and single-end 75 bp RNA sequencing was performed using Illumina NextSeq 550 instrument followed by gene-level differential expression analysis. Functional analysis was carried out on information related to the role of genes, such as signaling pathways and biological processes. Plasma metabolomic measurement was performed with the Biocrates MxP Quant 500 Kit. RESULTS: We identified 144 differentially-expressed genes in PBMCs between headache and headache-free samples and 163 between symptom-free patients and controls. Network analysis revealed that enriched pathways included inflammation, cytokine activity and mitochondrial dysfunction in both headache and headache-free samples compared to controls. Plasma lactate, succinate and methionine sulfoxide levels were higher in migraineurs while spermine, spermidine and aconitate were decreased during attacks. CONCLUSIONS: It is concluded that enhanced inflammatory and immune cell activity, and oxidative stress can play a role in migraine susceptibility and headache generation.

RESUMO

BACKGROUND: Altered glutamatergic neurotransmission and neuropeptide levels play a central role in migraine pathomechanism. Previously, we confirmed that kynurenic acid, an endogenous glutamatergic antagonist, was able to decrease the expression of pituitary adenylate cyclase-activating polypeptide 1-38, a neuropeptide with known migraine-inducing properties. Hence, our aim was to reveal the role of the peripheral kynurenine pathway (KP) in episodic migraineurs. We focused on the complete tryptophan (Trp) catabolism, which comprises the serotonin and melatonin routes in addition to kynurenine metabolites. We investigated the relationship between metabolic alterations and clinical characteristics of migraine patients. METHODS: Female migraine patients aged between 25 and 50 years (n = 50) and healthy control subjects (n = 34) participated in this study. Blood samples were collected from the cubital veins of subjects (during both the interictal/ictal periods in migraineurs, n = 47/12, respectively). 12 metabolites of Trp pathway were determined by neurochemical measurements (UHPLC-MS/MS). RESULTS: Plasma concentrations of the most Trp metabolites were remarkably decreased in the interictal period of migraineurs compared to healthy control subjects, especially in the migraine without aura (MWoA) subgroup: Trp (p < 0.025), L-kynurenine (p < 0.001), kynurenic acid (p < 0.016), anthranilic acid (p < 0.007), picolinic acid (p < 0.03), 5-hydroxy-indoleaceticacid (p < 0.025) and melatonin (p < 0.023). Several metabolites showed a tendency to elevate during the ictal phase, but this was significant only in the cases of anthranilic acid, 5-hydroxy-indoleaceticacid and melatonin in MWoA patients. In the same subgroup, higher interictal kynurenic acid levels were identified in patients whose headache was severe and not related to their menstruation cycle. Negative linear correlation was detected between the interictal levels of xanthurenic acid/melatonin and attack frequency. Positive associations were found between the ictal 3-hydroxykynurenine levels and the beginning of attacks, just as between ictal picolinic acid levels and last attack before ictal sampling. CONCLUSIONS: Our results suggest that there is a widespread metabolic imbalance in migraineurs, which manifests in a completely depressed peripheral Trp catabolism during the interictal period. It might act as trigger for the migraine attack, contributing to glutamate excess induced neurotoxicity and generalised hyperexcitability. This data can draw attention to the clinical relevance of KP in migraine.

RESUMO

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.

RESUMO

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.

RESUMO

INTRODUCTION: An estimated 20-30% of patients with ulcerative colitis need surgery. The generally accepted procedure for the surgical treatment is total proctocolectomy with ileal pouch-anal anastomosis. Nowadays laparoscopic technique is used more frequently. AIM: Our aim was to compare the last 13 years results of patients treated with conventional and laparoscopic methods. METHOD: Between 01. 01. 2005 and 31. 05. 2018, 89 patients (n = 48 female, n = 41 male) received surgery. The mean age of the patients was 45.06 ± 14.4 and 39.8 ± 13.4 years in the laparoscopy and the open surgery groups. General status of patients, early and late results of surgical treatment, mainly complications and quality of life, were analyzed. RESULTS: There was no difference between the groups in hospital stay (10.3 ± 3.3 vs. 11.2 ± 3.7 days) and need for transfusion (2.6 ± 2.2 vs. 2.8 ± 1.7 units). During the follow-up period, the time to the recovery of the bowel function (1.2 ± 0.5 vs. 1.6 ± 0.7 days), the number of days spent in the intensive care unit (2.1 ± 0.9 vs. 2.5 ± 1.6 days) and the occurrence of late complications, such as intestinal obstruction, septic condition, postoperative hernias and 'other' complications were significantly lower in the laparoscopically operated group of patients. In the case of acute operations, the laparoscopic technique provided significantly better recovery of the bowel function (1.2 ± 0.4 vs. 1.8 ± 0.7 days). CONCLUSION: During the surgical treatment of ulcerative colitis, the minimally invasive technique provided more favourable perioperative results and a better long-term quality of life due to the lower rate of late complications and the more stable psychic status.
