Excellent antibacterial activity of Slovak honeys on bacteria mostly infecting chronic wounds.

INTRODUCTION AND AIM OF STUDY: Chronic wounds are commonly colonized by various bacterial species and colonization frequently turns into wound infection, severely impairing healing process. With increasing antimicrobial resistance, the antimicrobial treatment of chronic wounds may be extremely challenging. Rediscovery of old and forgotten antimicrobial therapeutic options, such as apitherapy, may contribute to solving the problem of incurable chronic wound infections. Aim of this study was to evaluate the antimicrobial properties of four kinds of Slovak honey from ecological beekeeping against the most common bacterial species contaminating and infecting chronic wounds, and to compare these antimicrobial activities with those of the approved medical-grade Manuka honey. The impact of honey sterilisation methods and long-lasting storage on the bactericidal activity was also examined. MATERIAL AND METHODS: Antimicrobial activity of honey was detected against 7 bacterial collection strains by broth microdilution antimicrobial susceptibility test according to EUCAST. The results were statistically analysed by Fisherꞌs exact test. RESULTS AND CONCLUSIONS: Slovak ecologically produced honey samples demonstrated an excellent in vitro antibacterial activity, superior to the monofloral medical-grade Manuka honey activity. Neither the gamma-irradiation, nor the three-year-long storage had impact on the bactericidal activity of the tested honey (Tab. 4, Fig. 2, Ref. 53).

Design of abdominal retractor.

INTRODUCTION: The purpose of this paper is to present the development and design of an abdominal retractor which allows a single person to perform operations and the fixation of the operation instruments can be done with one hand. The additional devices make the operation more comfortable for surgeons. METHODS: Conventional measuring devices have been designed and applied for determining axial forces in a surgeon's forearm during operations. The same forces must be transmitted by the frame of the retractor. Thus a simple truss structure of a retractor was done. Several types of fixations have been proposed and tested using the rapid prototyping. Finally, the abdominal retractor was manufactured from stainless steel. RESULTS: The simple-to-use abdominal retractor was built. The standard surgery instruments were modified due to the fixation system of the frame. A wide variety of additional useful devices, such as a lamp, video camera etc., were also proposed. CONCLUSION: The present abdominal retractor is user-friendly and all components are easily sterilized by conventional methods (Fig. 7, Ref. 6) Keywords: abdominal retractor, stainless steel retractor, standard surger, fixation system of the frame, lamp, video camera, conventional methods.

Maggot therapy in treatment of a complex hand injury complicated by mycotic infection.

Complex injuries of the hand remain a therapeutic challenge for surgeons. We present the case of a male who suffered a devastating injury of the hand caused by a conveyor belt. The patient developed a progressive Absidia corymbifera infection of the affected soft tissues. Initial treatments with serial surgical debridement and topical and intravenous itraconazole were unsuccessful in eliminating the infection. We decided to use maggot debridement therapy in a new special design to debride all necrotic, devitalized tissue and preserve only healthy tissue and functioning structures. This maneuverer followed by negative pressure therapy allowed progressive healing. In such complex hand injuries, maggot debridement combined with negative pressure therapy could be considered to achieve effective and considerable results, although future functional morbidity may occur (Fig. 4, Ref. 18).

Monitoring of hands movement trajectories in the field of laparoscopic and endoscopic surgeries and options in the clinical practice.

Within the project "Applied research trajectory hands in laparoscopic and endoscopic operations", ITMS Project code 26240220056, funded by the European Regional Development Fund and the state budget of the Slovak Republic, we created a technical background and algorithms for monitoring and evaluating the hand movements of the surgeon during laparoscopic and endoscopic operations. This is a unique idea and unique project transformed into clinical practice, which is promising to assist in laparoscopic training and inclusion of surgeon / endoscopist to "skilfulness" group on the evaluation of the effectiveness of movements of his hands (Tab. 2, Ref. 11).

Gastric stimulation in treatment in type 2 diabetes mellitus.

UNLABELLED: Metabolic surgery is a dynamic field providing a wide range of new techniques. The aim of our paper is to inform about gastric electrostimulation in the treatment of type 2 diabetes mellitus. Gastric electrostimulation in type 2 diabetes mellitus treatment is performed by means of implanting Tantalus system (Metacure). When triggered by food intake, the Tantalus system generates signals for the stomach to contract. Early after the food intake, thus before the stomach distends completely, the system increases spontaneous stomach contractions. Via afferent vagal signals, these increased contractions are evaluated by the central nervous system as a sign that satiety has been reached. Three pairs of electrodes connected with a stimulator are implanted laparoscopically. The system comes equipped with a battery as well. Laparoscopically implanted system of stomach electrostimulation presents a simple and easily regulated system without disturbing the integrity of gastrointestinal tract. It is a reversible system. In accord with preliminary results, Tantalus offers a safe and effective treatment of type 2 diabetes mellitus by reducing other cardiometabolical risky factors. The operation safety is comparable with that of similar minimally invasive surgical techniques. In order to improve our understanding of diabetes mellitus pathophysiology as well as of effects of gastric electrostimulation, more trials need to be performed. The surgical diabetes treatment represents an interesting chance for patients and it might become a common technique in the future (Fig. 1, Ref. 29). KEYWORDS: diabetes mellitus, obesity, gastric stimulation, pacemaker.

Reccurent bleeding from Meckel's diverticulum - surgeon's challenge.

The authors of this paper want to share their experience with diagnostic and therapeutic problems in case of chronic small intestinal bleeding from Meckel's diverticulum, which ended with acute episode of massive gastrointestinal bleeding requiring emergent surgery.Despite the progress achieved in diagnosing the sources of gastrointestinal bleeding, the diagnosis of small intestinal bleeding is very frequently beyond the ability of making it right, and thus emergent surgery is often the only possibility of saving the patient's life on the one hand, and allowing stating the correct diagnosis on the other (Fig. 1, Ref. 6).

The role of laparoscopic Heller myotomy in the treatment of achalasia.

AIM: To evaluate the results of laparoscopic Heller myotomy in our group of patients. METHOD: A retrospective clinical trial was carried out to evaluate the indication, technique and controversies of laparoscopic Heller myotomy in the achalasia treatment. The following symptoms were evaluated prior and after Heller myotomy: dysphagia, heartburn, nausea/vomiting after meal and asthma/coughing. The patients were evaluated by the use of Likert score. Statistical analysis was performed by using Student t test. The intra-operative (operation time, intraoperative complications, blood loss, conversion rate), and peri-operative parameters (morbidity, mortality, hospital stay) were evaluated as well. The patients who underwent laparoscopic Heller myotomy were included in the trial. All patients were perioperatively managed by a multidisciplinary team. RESULTS: The evaluation of fourteen patients was performed (average age: 53.2 yrs., eleven men, two women, BMI 23.6 kg/m(2)). The patients were indicated for surgery in all of the stages (I-III). Previous semiconservative therapeutic modalities were performed in thirteen patients. The standard laparoscopic technique for Heller myotomy with semifundoplication was applied. All the observed symptoms were statistically improved after the surgery (p=0.05). The average operating time was 89 minutes. Intraoperative blood loss was below 20 ml. There was no conversion to open surgery. An average hospital stay was 4.3 days. Morbidity was 14.3 % and mortality 0 %. In one patient esophageal mucosa perforation was intra-operatively identified and sutured. Post-operative course in this patient was without any complications. CONCLUSION: The laparoscopic Heller myotomy has become the "gold standard" procedure for achalasia. It is an excellent method allowing precise operation technique with good visualization of the esophagogastric junction. The operation with this approach is safe, efficient, and with excellent reproducible operative results. The correct and early indication for surgery is crucial. The delayed diagnosis with a late indication for surgery is not an exemption (Tab. 2, Fig. 2, Ref. 36).

Comparison of self-gripping mesh with mesh fixation with fibrin-glue in laparoscopic hernia repair (TAPP).

AIM: Comparison of self-gripping mesh with fibrin-glue mesh fixation for laparoscopic hernia repair using TAPP technique. MATERIALS AND METHODS: The trial has a prospective randomized design. The primary end-point was the evaluation of pain at 2 days, 1 month, and 3 months after surgery. The pain occurring 3 months after the surgery was considered as chronic pain. RESULTS: We have compared a group of 50 patients with self-gripping mesh with a group of 50 patients with fibrin glue mesh fixation using TAPP technique. There was no statistical difference between the basic group parameters (sex distribution, average age). There was no significant difference between the groups in terms of postoperative pain 1 month and 3 months after the surgery (p>0.05). There was no patient with chronic pain at 3-month follow-up in our trial. The mean operation time was 44 minutes in the group with self-gripping mesh and 48.5 minutes in the group with fibrin glue mesh fixation. There was a significant difference between both groups (p=0.006) CONCLUSION: Both fixation methods appear to be a well-tolerated alternative to classical methods for mesh fixation with clips. According to our trial there is no difference in the postoperative pain incidence in self-gripping mesh and fibrin glue mesh fixation groups for laparoscopic hernia repair. Our data has showed that self-gripping mesh represents a tendency to a faster technique in comparison with fibrin-glue fixation. Both techniques are easy-to-use. There is no superior technique according to our trial (Tab. 2, Fig. 2, Ref. 23).

The combined algorithm of venous ulcer therapy.

AIM: This prospective study was undertaken to find a new combined algorithm to help patients suffering from long-term chronic non-healing venous ulcers. METHODS: A total number of 20 patients suffering from chronic venous ulcers and important co-morbidities such as diabetes mellitus or cardiac failure and not responding to other therapeutic modalities were treated at our surgical department with a combination of compressive sclerotherapy, and maggot debridement therapy (MDT) using larvae of green blowfly Lucilia sericata. RESULTS: Using the combined therapy we have achieved a significant clinical effect in 19 patients (95 %). In 1 patient, this effect was only impermanent while 5 patients (25 %) were completely cured. Eleven patients (55 %) benefited despite incomplete healing of the ulcer. With three of our patients we have lost contact. CONCLUSIONS: Even though the number of patients in our study is not large, we have achieved remarkable results with the combined algorithm of venous ulcer therapy. We start the healing process with compressive sclerotherapy and when this kind of therapy does not bring about the expected effect, we continue with Maggot debridement therapy. This combination of therapeutic modalities appears to be very effective and efficient (Fig. 2, Ref. 16).

Rare conditions of gastrointestinal bleeding.

The aim of this paper is to analyze and discuss an infrequent topic, i. e. rare conditions of gastrointestinal bleeding.Bleeding from gastrointestinal system is a common cause of acute abdomen and the most frequent causes are generally known.Clinicians, first of all emergency medicine staff, surgeons and internists (gastroenterology specialists), general practitioners, or less frequently other specialists, sometimes meet with less common causes of acute or chronic bleeding from gastrointestinal organs. It is quite important to be aware of the possibility the bleeding being caused by some rare condition, which is not so often met in medical practice, because of their great diagnostic and therapeutic problem. The low index of expectation of such a rare etiological unit could be the reason why destiny of such patients can be extremely problematic and why clinicians may fail at management of these patients (Fig. 4, Ref. 8).

[Retroperitoneoscopic adrenalectomy with dorsal approach]. / Retroperitoneoskopická adrenalektomie dorzálním prístupem.

UNLABELLED: INTRODUSTION: Various surgical mininvasive approaches for adrenalectomy have been established over the last two decades. We are evaluating the retroperitoneoscopic adrenalectomy with dorsal approach. MATERIAL AND METHODS: The prospective open clinical trial was carried out to evaluate intra-operative (operations time, intraoperative complications, blood loss, conversion rate) and peri-operative parameters (morbidity, mortality, hospital stay). Patients who underwent retroperitoneoscopic adrenalectomy with dorsal approach were included in the trial. A tumor size above 12 cm or BMI higher than 35 kg/m2 were considered asexclusion criteria. All the patients were perioperatively managed by a multidisciplinary team. RESULTS: A total of 81 patients were assessed (average age: 45.7 yrs, 37 males, 44 females, BMI 27.8 kg/m2). The average operating time was 61 minutes. The intraoperative blood loss was below 20 ml. The mean hospital stay was 2.1 days. Morbidity was 2.7% and mortality 0%. CONCLUSION: Retroperitoneoscopic adrenalectomy with dorsal approach is considered a method of choice in our hospital. The use of this approach is safe, efficient, with excellent reproducible operative results and impressive patient recovery.

Laparoscopic management of spontaneous intraperitoneal perforation of urinary bladder.

The authors present two cases of spontaneous intraperitoneal perforation of urinary bladder. The first case was a 56-year old female patient with history of urothelial cancer with partial urinary bladder resection and subsequent radiotherapy six years ago. The diagnostic laparoscopy was indicated because of the clinical signs of peritonitis. The diagnostic laparoscopy revealed a perforation of urinary bladder and the management of perforation was done laparoscopically. The histological examination of specimen revealed urothelial cancer. The postoperative course was uncomplicated and the patient underwent further oncologic treatment. The second patient was a 61-year old man admitted with abdominal pain lasting for one day after excessive alcohol intake. An indication to diagnostic laparoscopy was done according to the clinical signs of peritonitis. Also in this case, perforation of urinary bladder was identified and laparoscopic management was carried out. The postoperative course was uncomplicated. Both patients denied any trauma. The diagnosis of urinary bladder perforation was not done preoperatively. The diagnosis of spontaneous perforation of urinary bladder is difficult. The case history data with no trauma do not lead to this diagnosis. It is important to consider this diagnosis in case of acute abdomen. The treatment of urinary bladder perforation is based on the identification of the defect, lavage of the peritoneal cavity, excision of the defect, reconstruction of the bladder with intact blood supply, bladder drainage supporting the defect healing, and exclusion of malignancy. The laparoscopic treatment of spontaneous perforation according to literature is not common, however very effective (Fig. 1, Ref. 41).

From preoperative to intraoperative detection of hyperfunctioning parathyroid glands using tetrofosmin (99mTc) in primary hyperparathyroidism.

The impact of preoperative scintigraphy on the management of patients with primary hyperparathyroidism has been largely documented for more than two decades. More recently, preoperative scintigraphy has also been used to select patients for intraoperative detection of hyperfunctioning parathyroid glands thanks to a gamma-probe. This procedure is now widely used, with MIBI as the main radiopharmaceutical for both preoperative scintigraphy and intraoperative detection. However MIBI was not available in Slovakia until very recently and tetrofosmin (TF), the alternative 99mTc labelled radiopharmaceutical for myocardial imaging has some advantages over MIBI and a close biological behaviour. Thus we have been using TF also for parathyroid preoperative scintigraphy and for intraoperative detection, a systematic indication which has never been reported by others. This article aims to demonstrate the feasibility and to present our protocol for TF parathyroid imaging and intraoperative detection, closely associating surgeons, nuclear medicine specialists, pathologists and also biologists as intraoperative assay of intact PTH is necessary. The results of literature are subsequently reported and discussed (Tab. 2, Fig. 4, Ref. 35). Full Text in free PDF www.bmj.sk.

Complicated course after sleeve gastrectomy for obesity.

The authors present a case of a 52-year old female patient with sleeve gastrectomy for obesity. Two major complications occured after the surgery. The first one was a leakage on the third day after the surgery. The routine swallow examination on the first day after the surgery was normal. The pathological secretion from the drainage occurred on the third day after the surgery with a simultaneous increase in inflammatory markers. There were no clinical signs of sepsis. An indication for laparoscopic revision was done and a small defect in the staple line was identified. The oversewing of the small defect on the stomach was performed. Immediately after the second surgery the patient was clinicaly without any problems. The inflammatory markers decreased promptly after the surgery. The second complication was presented with decompensated psychosis, which developed on the 4th day after the second surgery. The patient complained of problems with swallowing despite the fact that the swallow contrast examination was normal. The patient received her psychiatric medication intravenously. The problem with swallowing was not based on any organic reason, and lasted for 4 weeks. During this period the patient was fed only parenterally. Almost 6 weeks after the surgery the patient became compensated and was dismissed. We would like to point out to the problems potentially occuring in patients with a psychiatric disease. Good compensation and stabilization of psychiatric disease is a condition that has to be met before a surgery (Tab. 1, Fig. 1, Ref. 21).

Autogenous venous valve construction.

AIM: The aim of this study was to assess the results of a new type of antireflux operation on the deep venous system in patients with venous ulceration not responding to treatment of the superficial system and compression. METHODS: In the period comprised between 1991-2002, the authors treated 56 patients with venous ulceration by Fegan's technique, that consists in compression sclerotherapy combined with antireflux operation of the deep veins. All patients selected had pathological reflux in the deep venous system and their ulcers did not respond to superficial and perforating vein therapy, and elastic compression. RESULTS: Using this technique of complex antireflux treatment, it was possible to heal 53 (95.4%) of the 56 ulcers with average time of complete ulcer epitelisation within 39+/-12 days. The recurrence rate, within the 5 year follow-up was 18% (10 patients), but 7 of the recurrent ulcers responded to compression sclerotherapy and healed within 3 months. CONCLUSIONS: In situ made valvuloplasty has several advantages: the valve is constructed from autogenous vein wall; all luminal valve surfaces have native venous endothelium; intraluminal foreign material is not introduced; the likelihood of thrombosis is reduced; the valve is size-matched to the host vein and this technique provides a competent bicuspid valve.

Ductal carcinoma of the breast in the pacemaker generator's pocket.

Authors present a case of a 78-year-old female patient with invasive ductal adenocarcinoma in the pacemaker, s pocket. A decubitus-like tumor had developed in this place, and has been missinterpretated as a benign lesion for 5 months. Diagnosis was done with a time delay. An excisional biopsy revealed annvasive ductal adenocarcinoma. The first step was the implantation of a new pacemaker generator performed on the opposite side. The second step was a modified radical mastectomy, according to Madden, and the removal of the originally implanted pacemaker generator. Radiotherapy and hormonal adjuvant therapy were applied after surgery. The patient was followed-up at an out-patient clinic, and died 25 months after diagnosis because of generalization of the disease (Fig. 2, Ref. 35). Full Text (Free, PDF) www.bmj.sk.

Venous leg ulcers--a surgical treatment.

OBJECTIVE: To asses the complex anti-reflux treatment of pure venous ulcers on all levels of venous system. PATIENTS: In the last 20 years the authors treated 793 patients with venous ulceration and compared the therapeutic results of 4 groups of patients treated either surgically (Linton+v.v. surgery) or with sclerotherapy (Fegan's technique) combined with the anti-reflux operation on deep veins in torpid ulcerations non responding to superficial and perforators therapy. RESULTS AND CONCLUSION: The authors consider a compression sclerotherapy (the Fegan's technique) the easiest and the most effective way of treating patients with venous ulcer. The direct valve repair techniques are appropriate only in non-thrombotic deep vein reflux, which is very rare (4 patients--0.6%). In patients with torpid ulcers, where the compression sclerotherapy failed (4.6%--28 pts), the in situ construction of a new valve could help (Tab. 2, Ref. 19). Full Text (Free, PDF) www.bmj.sk.

Profuse bleeding in patients with chronic venous insufficiency.

AIM: The aim of this retrospective study was to compare the healing rates of patients where the bleeding points were sutured (n=52) against those where the bleeding was controlled using compression sclerotherapy (n=72). The incidence of re-bleeding was also followed over a 12-month period. METHODS: During 1999-2003, we treated 124 patients (86 women and 38 men; mean age: 64 years, age range: 36-85 years) with profuse bleeding from varicose veins as emergency cases. Seventy-two patients (58%) were treated with compression sclerotherapy. In the suture group of 52 patients (42%) the bleeding points were treated in the emergency outpatients department. Usually a cross stitch was used and the same type of uninterrupted compression as in the sclerotherapy group was applied for 6 weeks afterwards. RESULTS: In the group of patients where compression sclerotherapy (Fegan's method) was used to control the bleeding (65 patients), the average time taken for the wound to heal completely was 7 days (5-13 days). There was no recurrence of bleeding in the subsequent 12 months. In the group of patients where a suture was used to control the bleeding, the average time of healing was 14 days (11-19 days) and re-bleeding occurred in 12 cases (23%). CONCLUSIONS: Using Fegan's technique of compression sclerotherapy with a low concentration of sclerosant (0.2% sodium tetradecyl sulfate), it is possible to treat bleeding varicose veins effectively with significantly faster healing of the wound.

The surgical anatomy of the nervus laryngeus recurrens.

In this study, the authors remind the readers the problem traditionally discussed in the thyroid gland surgery--protection of the nervus laryngeus recurrens (NLR) from iatrogenic damage. The aim of this study is to point out some anatomical details on the course of the recurrent nerve (Ref 4).
