Full textAim: This is a prospective study on the surgical treatment of patients who suffered from degenerative spinal stenosis of lumbar spine in multiple levels (2 or more). Our goal was to show if our technique improves substantially patient’s symptoms and if the improvement is long lasting. Patients and Method: Between 1997 and 2004, 41 patients were participated in this study, which took place at the Orthopaedic Department of Patras University Hospital. All patients had completed 1-year postoperative follow up. Mean age was 61 years (range 33 – 79 years). All patients underwent preoperatively detailed radiological and clinical evaluation. Radiological aproach included face, profile and dynamic x-rays, computer tomography (CT), magnetic resorance (MRI) and/or myelography with myelo-CT. Clinical evaluation was done using Oswestry Disability Index (ODI) and Visual Analog Scale (VAS). Twenty-three patients suffered from degenerative stenosis in 2 levels (included 3 vertebral bodies), in 16 patients were involved 3 levels and in 2 patients were involved 4 levels. Furthermore 12 patients suffered from concomitant scoliosis, 18 patients from concomitant spondylolisthesis (1st grade), 9 patients from segmental instability and 2 patients from scoliosis and spondylolisthesis. Patients’ symptoms were low back pain, sciatica and/or neurologic intermittent claudication. In 6 patients neurologic deterioration was observed. Surgical technique was wide posterior decompression. This included removal of spinous process, vertebral lamina and ligamentum flavum, and lead to fully posterior exposure of the spinal canal. Decompression was taken place in all the stenotic segments and was extended from one to another root canal in each segment. In order to achieve stability of the spine we used transpedicular screw fixation system, which extended one segment above and one below the decompressed area. Finally we used osseous graft and allograft between transverse processes. Mean surgical time was 228 (120-420) min. Patients’ follow up was done once per year and included the completion of ODI and VAS and face profile and dynamic x-rays for clinical and radiological assessment respectively. Results: Mean follow up was 3,7 (1-6) years. The quality of patients’ life, as is estimated with ODI, showed substantial improvement, which lasted all years. In specific from 61% preoperatively, improved to 16% the 4th postoperative year. Pain also presented statistical significant improvement, as is estimated with VAS. In specific from 7,9 preoperatively improved to 2,3 the 4th postoperative year. Evaluation of ODI’s parameters showed that the greater improvement was achieved in pain, personal care, sitting, sleeping and traveling. More than 90% of the patients had normal or nearly normal activity in these aforementioned parameters, the 4th postoperative year. Two patients had instability in an adjacent level (4,9%). Also one screw breakage in 1 patient (2,4%) and one screw loosening in another one (2,4%), both in S1 vertebral, was observed. These 4 patients underwent second surgical intervention due to instability. Finally there was possibility 90,2% for the patients not to underwent second operation due to mechanical failure. The rest of the patients presented with solid fusion, confluent osseous bridging between the transverse processes and stable adjacent vertebral levels. Conclusions: Wide posterior decompression combined with posterolateralinstrumented fusion, lead to satisfactory and reproducible clinical and radiological results to patients who suffer from degenerative lumbar spinal stenosis in multiple levels with concomitant instability (degenerative scoliosis and/or degenerative spondylolisthesis). The aforementioned technique avoids substantial bone regrowth and stenosis recurrence. Proper use in carefully selected patients has low complication rate, giving us a good and long-lasting result.

Full textMicrosurgical free tissue transfer considered as the best choice for the reconstruction of head and neck extended and complex tissue defects due to tumor resection or trauma. A total of 48 patients underwent free tissue transfer between 2003-2010. There were 34 patients underwent one stage tumor resection and microsurgical free flap reconstruction and 16 patients for free flap reconstruction due to head and neck trauma. The defect in 12 patients 25% was on the scalp and forehead, the middle third in 9 patients 18.7% lower third in neck in 27 patients 56.25%. We used a combination of double free flaps for reconstruction in 7 cases and in 41 patients a single free flap. Vane grafts were used in 16 cases (33.3%). We used in total 56 free flaps with success rate 92.8% (52/56). Four flaps were lost due to anastomotic thromboses. Work horse flaps in our series include the radial forearm 28.5%, fibula 17.8%, ALT 14.2%, VRAM 12.5%, TRAM 5.3%, latissimus dorse 8.9%, gracilis 7.1% and serratus anterior 1.7%. The neck recipient vessels were used in 96.2%. One patient died in post surgical period after systemic complications. Preoperative surgical and reconstruction plan, flaps selection, high microsurgical experience and team collaboration are essential for the good functional and aesthetic results in microsurgery reconstruction of head and neck tissue defects.

Full textΗ θρεπτική κατάσταση κατά τη διάρκεια της εγκυμοσύνης και οι συνέπειες διατροφικών ανεπαρκειών στην έκβαση της, που ακολουθεί μια χειρουργική επέμβαση για κλινική σοβαρή παχυσαρκία αποτελεί θέμα που χρήζει περαιτέρω έρευνας. Σκοπός της συγκεκριμένης μελέτης ήταν η διερεύνηση της θρεπτικής κατάστασης και της έκβασης της εγκυμοσύνης, τόσο στις μητέρες όσο και στα νεογνά, σε γυναίκες που είχαν υποβληθεί στο παρελθόν σε περιοριστικές και δυσαπορροφητικές επεμβάσεις για κλινικά σοβαρή παχυσαρκία. Μελετήθηκαν 113 γυναίκες που γέννησαν 150 παιδιά μετά από χολοπαγκρεατική εκτροπή (BPD), Roux-en-Y γαστρική παράκαμψη (RYGB) και επιμήκη γαστρεκτομή μεταξύ Ιουνίου 1994 και Δεκεμβρίου 2011. Συγκρίθηκαν τα αποτελέσματα των θρεπτικών δεικτών και της έκβασης της εγκυμοσύνης μεταξύ των επεμβάσεων καθώς και με τα 20ετή στοιχεία γεννήσεων του νοσοκομείου μας και τα αποτελέσματα από 56 προεγχειρητικές εγκυμοσύνες σε 36 από τις ίδιες γυναίκες. Αναιμία παρατηρήθηκε σε 24.2% και 15.6% των κυήσεων μετά από BPD και RYGB, αντίστοιχα. Τα επίπεδα της βιταμίνης B12 μειώθηκαν μετεγχειρητικά σε όλες τις ομάδες, χωρίς περαιτέρω μείωση κατά τη διάρκεια της εγκυμοσύνης• όμως, χαμηλά επίπεδα παρατηρήθηκαν σε κάποιες γυναίκες όχι μόνο μετά από BPD (11.7%) και RYGB (15.6%), αλλά και μετά από SG (13.3%). Τα επίπεδα του φυλλικού οξέος αυξήθηκαν μετεγχειρητικά και κατά τη διάρκεια της εγκυμοσύνης. Η τιμή της αλβουμίνης μειώθηκε σε όλες τις ομάδες κατά τη διάρκεια της εγκυμοσύνης, αλλά υποπρωτεϊναιμία παρατηρήθηκε μόνο μετά από BPD. Τα νεογνά μετά από BPD είχαν χαμηλότερο μέσο όρο βάρους γέννησης (p<0.05), χωρίς να υπάρχει μεγαλύτερη συχνότητα χαμηλού βάρους γέννησης (<2500gr). Η σύγκριση μεταξύ των νεογνών που γεννήθηκαν πριν και μετά το χειρουργείο έδειξε ότι τα νεογνά που γεννήθηκαν μετά είχαν χαμηλότερο βάρος (p<0.001) χωρίς σημαντικές διαφορές στη διάρκεια κύησης, στο μήκος ή στην περίμετρο της κεφαλής και καθόλου μακροσωμία. Συμπερασματικά, η δική μας μελέτη έδειξε σχετικά καλή θρεπτική κατάσταση και έκβαση στη εγκυμοσύνη μετά από όλους τους τύπους επεμβάσεων στη συγκεκριμένη πληθυσμιακή ομάδα εφόσον υπάρχει συστηματική παρακολούθηση και ακολουθούνται οι διατροφικές οδηγίες. Πιο στενή παρακολούθηση χρειάζεται μετά από δυσαπορροφητικές επεμβάσεις ιδιαίτερα ως προς το θέμα της πρωτεϊνικής θρέψης

Full textBariatric surgery has been shown to be effective in providing substantial and sustained long-term weight loss with minimum complications. Following bariatric surgery and consequent loss of body weight, the skin begins to sag in various regions of the body, forming skin-folds, which cause serious functional, dermatological and aesthetic deformities. The regions of the body most commonly affected by excess skin tissue are the medial part of the arms, the breasts, the thoracic and abdominal wall, especially in the lateral areas and the inner and outer thigh. In order to correct this deformity, it is essential that they undergo a series of one or more regional dermolipectomies. In this article, we present our experience on how we manage these patients. From October 1996 until December 2002, 46 patients had 67 regional dermolipectomies. Forty-five patients underwent abdominal dermolipectomy. The average operative time was 188,1 min (105-420min). The average amount of tissue excised was 2839,2 gr (850-7525gr). Four patients (8,8%) required blood transfusion. Seven patients (15,5%) developed complications, which included 1 case of post-operative bleeding, 3 wound infections, 2 skin dehiscences and 1 seroma. Average length of hospital stay was 8,9 days (5- 22 days). Twenty-five of these patients (55,5%) simultaneously underwent abdominal incisional hernia repair; in 9 (20%), a goretex mesh was used. Eight patients (17,3%) had mammaplasty, with average operative time 166,2 min (130-210 min). In one of them, breast implants were placed. There was no morbidity, and the average hospitalization was 7,1 days (4-9 days). Transverse flank-thigh-buttock lift was done in seven patients (8,6%), and arm reduction plasty in three (6,5%). The average operative time was 297,1 min (160-420 min), 246,2 min (230-280 min) and 203,3 min (180-240) respectively. Average tissue excised was 2245 gr (725-4403 gr), 1342,5 gr (1050-1550 gr) and 572,7 gr (400-848 gr) respectively. Morbidity was related to wound infection in 2 patients, minor skin dehiscence in 5 patients and persistent edema of the left lower extremity in another. Average hospitalization was 10,6 days (6-23 days), 8 days (7-8 days) and 6 days (5-7 days) respectively. Regional dermolipectomies constitute the only available treatment for deformities following massive weight loss after bariatric surgery. Based on our experience, these procedures are safe, without serious complications and with good functional and esthetic results.

Full textNatural Orifice Transluminal Endocopic Surgery (NOTES) is perhaps the most interesting achievement of today’s surgery in terms of technique. The development of computer technology and robotics is a powerful tool for the modern surgeon. The progress of micro-robotics today is remarkable. Robotic working teams continuously produce smaller in size robots with more potential motion and signal processing that can enter into the peritoneal cavity through the body’s natural orifices. NOTES surgery is perhaps ideal for use of micro-robots. This combination could be a revolution for the Telesurgery. The aim of our work is to highlight the role of medical informatics in the use of micro-robots in NOTES surgery. We designed and simulated a model of an articulated micro-robot composed of subunits (modular robot) that can enter the gastrointestinal tract or the peritoneal cavity through the body’s natural orifices. It is capable of motion and surgical manipulations and can also provide sensor information to the user.-
