RESUMEN

BACKGROUND: Arteriovenous fistula (AVF) is the vascular access of choice for hemodialysis patients. A correct microsurgical vascular anastomoses is essential to the optimal care of patients. Loupes can help surgeons perform such procedures, but often cause neck or back pain and fatigue. AIM: This study aimed to evaluate whether a video telescopic operating microscope (VITOM®; Karl Storz Endoscopy GmbH, Tuttlingen, Germany) could be used as a substitute for loupes to create microsurgical vascular anastomoses. METHODS: We evaluated microsurgical anastomoses with VITOM® in 10 patients (6 male, 4 female) from January 2019 to December 2019. The created anastomoses were 7 side-to-side, 2 side-to-end and 1 end-to-end. RESULTS: A valid thrill was always present on palpation. Surgical procedures had an average time of 87.6 min, ranging from 49 to 110 min. Eight patients had AVF maturation; in the remaining 2, one had a thrombosis after 25 days and one couldn't be dialyzed due to low flow in AVF. CONCLUSIONS: The VITOM® system makes it possible to carry out anastomosis in difficult cases. It is both safe and useful for the training of young surgeons.

RESUMEN

BACKGROUND: laparoscopic adrenalectomy has become the standard treatment for adrenal lesions. The better clinical outcoms of laparoscopic technique are valid for treatment of small benign masses (< 5-6 cm), instead there are still open questions in literature regarding the correct management of larger lesions (> 6 cm) or in case of potentially malignant adrenal tumors. The aim of this study is to evaluate the outcomes of laparoscopic adrenalectomy in a referral surgical department for endocrine surgery. METHODS: at the University Hospital Policlinico "P. Giaccone" of Palermo between January 2010 and December 2017 we performed a total of 81 laparoscopic adrenalectomy. We created a retrospective database with analysis of patients data, morphologic and hormonal characteristics of adrenal lesions, surgical procedures and postoperative results with histological diagnosis and complications. RESULTS: Mean size of adrenal neoplasm was 7,5 cm (range 1.5 to 18 cm). The mean operative time was 145 min (range 75-240). In statistical analysis lenght of surgery was correlated to the lesion diameter (p < 0.05) but not with pre-operative features or histological results. 5 intraoperative complications occurred. Among these patients 4 presented bleeding and 1 a diaphagmatic lesion. No conversion to open surgery was necessary and no intraoperative blood transfusion were required. Mean estimated blood loss was 95 ml (range 50-350). There was no capsular disruption during adrenal dissection. Mean length of hospital stay was 3.7 days (range 3-6 days). CONCLUSIONS: Laparoscopic adrenalectomy is a safe procedure with low rate of morbidity. An accurate preoperative radiological examination is fundamental to obtain a stringent patients selection. The lesion diameter is related to longer operative time and appeares as the main predictive parameter of intraoperative complications but these results are not statistically significant. On the other side secreting adrenal tumors require more attention in operative management without increased rate of postoperative complications.

RESUMEN

Automatic vascular staplers for vascular anastomoses in kidney transplantation may dramatically reduce the operative time and, in particular, warm ischemia time, thus increasing the outcome of transplantation. Ten pigs underwent kidney auto-transplantation by automatic anastomotic device. Kidneys were collected by laparotomy with selective ligations at the renal hilum and perfused with cold storage solution. To overcome the shortage in length of renal hilum, a tract of the internal jugular vein was harvested to increase the length of the vessels. The anastomoses were totally performed by the use of the anastomotic device. On 10 kidney transplants, nine were successful and no complications occurred. Renal resistive indexes showed a slight increase in the immediate postoperative period returning normal at 10 days of follow-up. We demonstrated the possibility to perform renal vascular anastomoses by means of an automatic anastomotic device. This instrument developed for coronary bypass surgery by virtue of the small caliber of the vessels could be adopted on a larger scale for renal transplantation. The reduced warm ischemia time needed for anastomosis may help to achieve a better outcome for the graft and expand the pool of marginal donors in renal transplantation.

RESUMEN

Adenomyotic cysts are uncommon findings, usually in the context of diffuse adenomyosis and <5 mm in diameter. Herein we report a 4.5-cm adenomyotic cyst in a 25-year-old nulliparous woman with severe dysmenorrhea and pelvic pain. Transvaginal ultrasonography and magnetic resonance imaging revealed a well-circumscribed hypoechogenic mass in the posterior uterine wall, well separated from the uterine cavity. Pathologic analysis demonstrated that the cyst was lined with endometrial epithelium and stroma and was surrounded by smooth muscle hyperplasia. In the literature, we found 30 reports of cysts with similar characteristics. Because this cyst has not been clearly defined, it has been called by various names including adenomyotic cyst, cystic adenomyosis, and cystic adenomyoma. We believe this lesion should not be called an adenomyoma, but is more correctly called an adenomyotic cyst or, depending on age at onset, a juvenile adenomyotic cyst.

RESUMEN

To date, the exact pathophysiology of haemorrhoids is poorly understood. The different philosophies on haemorrhoids aetiology may lead to different approaches of treatment. A pathogenic theory involving a correlation between altered anal canal microflora, local inflammation, and muscular dyssynergia is proposed through an extensive review of the literature. Since the middle of the twentieth century, three main theories exist: (1) the varicose vein theory, (2) the vascular hyperplasia theory, and (3) the concept of a sliding anal lining. These phenomena determine changes in the connective tissue (linked to inflammation), including loss of organization, muscular hypertrophy, fragmentation of the anal subepithelial muscle and the elastin component, and vascular changes, including abnormal venous dilatation and vascular thrombosis. Recent studies have reported a possible involvement of gut microbiota in gut motility alteration. Furthermore, dysbiosis seems to represent the leading cause of bowel mucosa inflammation in any intestinal district. The alteration of the gut microbioma in the anorectal district could be responsible for haemorrhoids and other anorectal disorders. A deeper knowledge of the gut microbiota in anorectal disorders lays the basis for unveiling the roles of these various gut microbiota components in anorectal disorder pathogenesis and being conductive to instructing future therapeutics. The therapeutic strategy of antibiotics, prebiotics, probiotics, and fecal microbiota transplantation will benefit the effective application of precision microbiome manipulation in anorectal disorders.

RESUMEN

BACKGROUND: Anatomic unexpected variations in biliary tree may be discovered during laparoscopic cholecystectomy. CASE REPORT: A 57-year-old man was admitted for abdominal pain, vomiting and mild jaundice. Abdominal ultrasonography revealed a gallbladder containing multiple stones and biliary sludge. All pre-operative investigations showed no anatomical variations in extrahepatic biliary tree. During surgical intervention an accessory extrahepatic duct, connecting the IV segment of the liver to the fundus of gallbladder, was discovered. CONCLUSIONS: Pre-operative routine investigations for gall stones diseases may not reveal anatomic variations of biliary tree.

RESUMEN

The gut of a healthy adult harbours a myriad of different microbial species. It is estimated that approximately 10 14 are present in total bacterial colony forming units (CFU). Each colony colonizes a specific intestinal tract. In healthy adult, the main control of intestinal bacterial colonization occurs through gastric acidity but also other factors can influence the intestinal microenvironment such as pH, temperature, competition among different bacterial strains, peristalsis, drugs, radiotherapy and much more. Impaired microbial homeostasis leads to an alteration of the permeability of tissue, together with the activation of the intestinal immune system MALT (mucosal associated lymphoid tissue). In this regard we discuss the increasing experimental evidences of the role of commensal microbiota in the activation of specific intestinal immunocompetent cells. The aforementioned micro-environmental changes provide the substrate for the etiopathogenetic outbreak of numerous pathologies of gastro-intestinal tract, such as intestinal chronic inflammation (Crohn's disease and Ulcerative Colitis), together with a miscellany of extra intestinal disorders. This article is an overview of the latest scientific findings about the close causal relationship between intestinal microbial flora and inflammatory bowel diseases or other extra-intestinal diseases; it is also mentioned the possible relationship between mycobacteria and Chron's disease. Finally we analyse the beneficial role of probiotics.

RESUMEN

Airway cancers have been increasing in recent years. Tracheal resection is commonly performed during surgery and is burdened from post-operative complications severely affecting quality of life. Tracheal resection is usually carried out in primary tracheal tumors or other neoplasms of the neck region. Regenerative medicine for tracheal replacement using bio-prosthesis is under current research. In recent years, attempts were made to replace and transplant human cadaver trachea. An effective vascular supply is fundamental for a successful tracheal transplantation. The use of biological scaffolds derived from decellularized tissues has the advantage of a three-dimensional structure based on the native extracellular matrix promoting the perfusion, vascularization, and differentiation of the seeded cell typologies. By appropriately modulating some experimental parameters, it is possible to change the characteristics of the surface. The obtained membranes could theoretically be affixed to a decellularized tissue, but, in practice, it needs to ensure adhesion to the biological substrate and/or glue adhesion with biocompatible glues. It is also known that many of the biocompatible glues can be toxic or poorly tolerated and induce inflammatory phenomena or rejection. In tissue and organ transplants, decellularized tissues must not produce adverse immunological reactions and lead to rejection phenomena; at the same time, the transplant tissue must retain the mechanical properties of the original tissue. This review describes the attempts so far developed and the current lines of research in the field of tracheal replacement.

RESUMEN

BACKGROUND: Wound healing is a complex and dynamic process. Healing of acute and chronic wounds can be impaired by patient factors (that is, comorbidities) and/or wound factors (that is, infection). Regenerative medicine products, such as autologous/homologous platelet-rich plasma gel, may speed up the healing process. Autologous/homologous platelet-rich plasma is an advanced wound therapy used for hard-to-heal acute and chronic wounds. The cytokines and growth factors contained in platelet-rich plasma play a crucial role in the healing process. CASE PRESENTATION: A 61-year-old Caucasian male patient, suffering from mental retardation following meningitis, with a transplanted kidney due to prior renal impairment, and under immunosuppressant therapy, was submitted to aneurysmectomy of his proximal left forearm arteriovenous fistula. A few days later, the patient came to our attention with substantial blood loss from the surgical site. The wound presented no signs of healing, and after fistula reparation and considering persistent infection of the surgical site (by methicillin-resistant Staphylococcus aureus), surgeons decided for second-intention healing. To favor healing, 10 mL homologous platelet concentrate gel was sequentially applied. After each application, wound was covered with nonadherent antiseptic dressing. After only seven applications of homologous platelet concentrate gel, wound completely recovered and no amputation was necessary. CONCLUSIONS: Topical application of homologous platelet-rich plasma gel in healing wound shows beneficial results in wound size reduction and induces granulation tissue formation. Platelet-rich plasma could be a safe and cost-effective treatment for managing the cutaneous wound healing process to shorten the recovery period and thereby improve patient quality of life.

RESUMEN

A simple technique for implanting a long-term jugular catheter in piglets under general anesthesia is described. We report our experience in 10 young female pigs with a body weight of 20-30 Kg. The surgical procedure involves implantation of a jugular central venous catheter (11Fr polyurethane) tunneled in the subcutaneous fat layer of the neck. This procedure may be performed in about 15 minutes. The maintenance of the catheter is described which allows several daily blood samples to be taken. This procedure reduces both the stress in piglets and the chance of catheter dislodgement due to the animals scratching or rubbing. Blood sampling can be easily performed with a low incidence of infection or thrombosis.

RESUMEN

BACKGROUND: Anastomotic recurrences of the colon are postulated to arise due to inadequate margins, tumor implantation by exfoliated cells, altered biological properties of bowel anastomosis, and missed synchronous lesions. In this paper, a case of unexpected early local recurrence after surgery for colon cancer is presented. CASE PRESENTATION: A 68-year-old Caucasian man underwent right hemicolectomy for invasive G2 adenocarcinoma. Two months later, endoscopy revealed a wide and well-functioning anastomosis with a hyperemic, hard, and thickened mucosal area of about 2 cm in diameter. Biopsies showed the presence of an adenocarcinoma with the same grading of the previous lesion. Ten days later, the patient underwent a new intervention; the last 10 cm of the ileum and half of the remaining transverse colon were resected, and the patient started adjuvant therapy. Specimen examination confirmed the presence of an adenocarcinoma (G2) penetrating the muscular layer of the wall; also, in this case, resection edges were free from tumoral invasion, and the removed lymph nodes were exempt from neoplastic colonization. The patient was seen in follow-up for about 5 years, and he did not show local or systemic manifestations. CONCLUSIONS: Whenever a neoplastic recurrence on the anastomotic line occurs, in the presence of negative intestinal margins, as usual in right colectomies, the implantation of neoplastic cells could be the possible cause.

RESUMEN

BACKGROUND: The lobar airway stenting remains an endoscopic procedure not well standardized in patients with locally advanced lung cancer disease. The goal of this study was to evaluate technical feasibility, clinical outcome, and complications of different stents in patients with malignant lesions involving lobar bronchi, primary and secondary carina. METHODS: Between November 2008 and October 2013, we retrospectively analyzed 146 patients with benign and malignant tracheobronchial stenosis who underwent airway stent insertion below main carina and main bronchi. RESULTS: In all, 170 airway stenting procedures were performed on 146 patients. In all, 51 of them with malignant peripheral airway stenosis underwent stents placement below main carina. In all but one patient, the deployment of stents was successful with improvement of symptoms. The chest radiograph after the procedure detected the lung re-expansion in 29 of 51 patients. The mean follow-up duration was 123 days ± 157. Complications observed included stent migration, tumor overgrowth, infections, granulation tissue formation, and obstruction due to tenacious secretions. Longer survival was observed in patients who received additional treatment after airway stenting compared to those who did not (p <0.01). CONCLUSIONS: Stenting of lobar bronchi and primary or secondary carina is technically feasible, effective, and acceptably safe.

RESUMEN

INTRODUCTION: Hepatic abscess can be defined as an encapsulated collection of suppurative material within the liver parenchyma. Hepatic abscess can be distinguished as pyogenic, amebic, or fungal. Biliary tract disease remains the most common cause of hepatic abscess today, and the most common complications range from pleural effusion, empyema, and bronchohepatic fistula to subphrenic abscess and rupture into the peritoneal cavity, stomach, colon, vena cava, or kidney. A large abscess compressing the inferior vena cava and the hepatic veins may result in Budd-Chiari syndrome. In this report, we present a rare case of hepatic abscess with an unusual evolution that was treated with a noninvasive approach. CASE PRESENTATION: A 79-year-old Caucasian woman underwent endoscopic bile stone extraction and laparoscopic cholecystectomy. Six months later, a hepatic abscess in association with bilateral effusion was diagnosed. The prompt imaging-guided drainage solved the case. Three years later, she came to our attention complaining of dull, diffuse abdominal pain and high body temperature (38 °C). A retroperitoneal abscess was diagnosed that was spreading to the right lateral wall of the abdomen and extending across the muscular wall to the subcutaneous layer. The fluid collection also involved the right pleural cavity, forming an empyema. Also in this case, an imaging-guided drainage was performed, and the patient's clinical picture resolved in a few days. The retroperitoneal abscess recurred 14 months later, and it was dealt with using the same treatment. Three months from the last follow-up, the patient came back to our attention with an evident swelling of her right lumbar region. Computed tomography revealed a right inferior lumbar hernia comprising adipose tissue and the right kidney. A surgical intervention was recommended to the patient, but, owing to her poor general health, she refused any invasive approach. CONCLUSIONS: Retroperitoneal abscess is an uncommon complication of biliary tract surgery and represents a potential cause of death, especially in those patients with multiple diseases. Prompt drainage is crucial to the treatment. Failure in eliminating the primary infective focus could bring complications and, in general, a weakness of lumbar muscular wall, even resulting in a rare case of lumbar hernia.

RESUMEN

Idiopathic granulomatous mastitis (IGM) is a chronic benign inflammatory disease of the breast that may mimic breast cancer. It is most common in parous young fertile women, although it can occur in nulliparous women and in men. IGM is an idiopathic disease due to the influence of some environmental factors in genetically predisposed subjects. Several pathogenic hypothesis have been proposed in the last years (autoimmune, hormonal, infective genesis). IGM presents as a painful palpable mass located in one of the two udders. The skin is usually normal but could present signs of inflammation with or without lymph nodes involvement. Ultrasonography, mammography, magnetic resonance can be diagnosed an IGM, but pathognomonic radiological signs has not yet reported in literature. Biopsy findings show granulomatous lesion centered on the breast lobule, as in granulomatous mastitis induced by tuberculosis or sarcoidosis. The aim of this review of literature is to verify the development of new advanced diagnostic techniques and multidisciplinary approach for this condition. In the last years innovative approaches have modified IGM diagnosis and therapy, avoiding surgery in most of cases, introducing a more conservative medical approach based on recent etiopathological hypothesis.

RESUMEN

BACKGROUND: A suitable, effective and free of complications anesthetic protocol is very important in experimental studies on animal models since it could bias the outcome of a trial. To date there is no universally accepted protocol for induction, maintenance and recovery from anesthesia. The endotracheal intubation with the use of inhalation anesthesia is used very especially in the from of large size laboratory animals, because it is a secure and easy control mode. However, it is not common for small laboratory animals because of the high technical skills required. AIM: The aim of this paper is a review of the main methods of induction of anesthesia in laboratory animals. MATERIALS AND METHODS: We performed an electronic search of MEDLINE (PubMed interface), ISI Web of Science and Scopus using the keywords "anesthesia" and "animal (s)" or "protocol (s)" or "surgery", without the data or the language restriction. We consider only the most common laboratory animals (rats, mice, rabbits, pigs). We identify all the scientific articles that refer to the use of anesthetics for studies on laboratory animals in all areas: experimental surgery, CT, MRI, PET. All documents identified the search criteria are subject to review only by identifying relevant studies. CONCLUSIONS: There is a strong need for application of existing guidelines for research on experimental animals; specific guidelines for anesthesia and euthanasia should be considered and reported in future studies to ensure comparability and quality of animal experiments.

RESUMEN

BACKGROUND: Secondary hyperparathyroidism is a common acquired disorder seen in chronic renal failure. Its pathophysiology is mainly due to hyperphosphatemia and vitamin D deficiency and resistance. When medical treatment fails, subtotal and total parathyroidectomy with autotransplantation are the standard procedures, although both are associated with high recurrence rates. METHODS AND RESULTS: 4 patients experienced persistence and 9 relapse. The first 4 were subjected to reoperation after 6 months for the persistence of symptoms due to the finding of a supernumerary adenomatous gland while the remaining patients at the reoperation showed in 5 cases 2 more glands in over thymic position, and 4 an hyperplasia of the residual glandular tissue. A classic cervicotomy was sufficient to remove the residual parathyroid in patients with persistent hyperparathyroidism. For cases of recurrent hyperparathyroidism it was enough a medial approach and sometimes lateral for the complete excision of the hyperplastic tissue. The advent of the intraoperative technique of parathyroid hormone dosage allowed a better performance of the surgical technique for the last 3 patients undergoing reoperation. After reoperation all patients had immediate regression of clinical symptoms with normalization of serum calcium and PTH levels. CONCLUSIONS: On the basis of these considerations, diagnostic imaging has a not negligible role because during the first intervention helps to have an idea of the possible location of the glands and thus to avoid the risk of recurrence and relapse due to ectopic or supernumerary tissue.

RESUMEN

BACKGROUND: Plasmoblastic lymphoma is a rare and aggressive subtype of diffuse large B cell lymphoma, which occurs usually in the jaw of immunocompromised subjects. CASE PRESENTATION: We describe the occurrence of plasmoblastic lymphoma in the mediastinum and chest wall skin of an human immunodeficiency virus-negative 63-year-old Caucasian man who had had polycytemia vera 7 years before. At admission, the patient showed a superior vena cava syndrome, with persistent dyspnoea, cough, and distension of the jugular veins. Imaging findings showed a 9.7 × 8 × 5.7 cm mediastinal mass. A chest wall neoformation biopsy and ultrasound-guided fine-needle aspiration biopsy of the mediastinal mass allowed diagnosis of plasmoblastic lymphoma and establishment of an immediate chemotherapeutic regimen, with rapid remission of compression symptoms. CONCLUSIONS: Plasmoblastic lymphoma is a very uncommon, difficult to diagnose, and aggressive disease. The presented case represents the first rare mediastinal plasmoblastic lymphoma in a human immunodeficiency virus-/human herpesvirus-8-negative patient. Pathologists should be aware that this tumor does appear in sites other than the oral cavity. Fine-needle aspiration biopsy is a low-cost, repeatable, easy-to-perform technique, with a high diagnostic accuracy and with very low complication and mortality rates. Fine-needle aspiration biopsy could represent the right alternative to surgery in those patients affected by plasmoblastic lymphoma, being rapid and minimally invasive. It allowed establishment of prompt medical treatment with subsequent considerable reduction of the neoplastic tissue and resolution of the mediastinal syndrome.

RESUMEN

BACKGROUND AND AIM: The aim of the present work is to evaluate the effectiveness of the use of ultrasound scalpel during laparoscopic ovariectomy in the bitch. METHODS: Two groups of 10 subjects each, of different races and ages, were compared. In the first group, ovariectomy was performed laparoscopically, using harmonic scalpel to remove ovary. In the second group surgery was performed by means of classical laparotomy. RESULTS: Pre-operative time was similar in both groups. Total operative time, from incision to skin suture, showed significant difference between the two groups, being laparoscopy faster than laparotomy. Partial operative time for bilateral oophorectomy resulted lower using open technique, but, considering each ovary, there was no significant difference in both groups. CONCLUSIONS: The use of harmonic scalpel to perform ovariectomy during laparoscopy is an effective time-sparing surgical approach compared to the already great practicality of laparotomy.

RESUMEN

INTRODUCTION: Endotracheal intubation in the rat is difficult because of the extremely small size of anatomical structures (oral cavity, epiglottis and vocal cords), small inlet for an endotracheal tube and the lack of proper technical instruments. MATERIAL AND METHODS: In this study we used seventy rats weighting 400-500 g. The equipment needed for the intubation was an operating table, a longish of cotton, a cotton tip, orotracheal tube, neonatal laryngoscope blades, KTR4 small animal ventilator and isoflurane for inhalation anaesthesia. Premedication was carried out by medetomidine hydrochloride 1 mg/mL; then, thanks to a closed glass chamber, a mixture of oxygen and isoflurane was administered. By means of a neonatal laryngoscope the orotracheal tube was advanced into the oral cavity until the wire guide was visualized trough the vocal cords; then it was passed through them. The tube was introduced directly into the larynx over the wire guide; successively, the guide was removed and the tube placed into the trachea. Breathing was confirmed using a glove, cut at the end of a finger, simulating a small balloon. RESULTS: We achieved a fast and simple orotracheal intubation in all animals employed. CONCLUSIONS: We believe that our procedure is easier and faster than those previously reported in scientific literature.

RESUMEN

Primary Neuroendocrine Tumours (NETs) of the gallbladder are rare. Among all NETs of the gallbladder, large cell neuroendocrine carcinoma (LCNEC) is exceedingly rare. In most of the cases LCNECs are combined with other histological components. We reviewed clinical presentation and management of all patients with "pure" LCNEC from published literature since the first case was published in 2000, as well as one patient from our experience. Only 7 cases of "pure" LCNEC has been described in the last 15 years, our case is the eighth. The diagnosis of gallbladder NETs is rarely made preoperatively since the presentation generally consists of non-specific symptoms including upper abdominal pain, discomfort, jaundice, weight loss. The majority of patients are identified incidentally at the time of cholecystectomy for cholelithiasis. It is not possible to differentiate preoperatively between gallbladder adenocarcinoma and gallbladder neuroendocrine carcinoma (NEC) with imaging techniques. The only curative therapeutic modality for LCNECs is a complete en bloc surgical resection, including regional lymph node clearances and hepatic lobectomy, but only in patients without multiple metastasis. LCNECs benefit from an aggressive surgical resection in combination with chemotherapy, if resectability is possible. If the tumour is non-resectable, the primary management is therefore medical and not surgical. All patients with LCNEC presented a poor prognosis with a median survival of 10 months after the initial diagnosis. Only in five patients (62.5%) a wide surgical excision was performed, while in the other cases the tumour was non-resectable or multiple liver metastases were present at diagnosis.
