Surgical treatment of thymoma: personal experience.

INTRODUCTION: Thymomas (THs) are rare epithelial tumors of the thymus gland. In this study we report our personal experience in the management and surgical treatment of THs. CASE REPORTS: We report two clinical cases treated with combined therapy (surgery followed by adjuvant therapy). RESULTS: Total transternal thymectomy was performed in both patients. The post-operative course was uneventful. The patients received adjuvant radiotherapy and chemotherapy. No relapse has been observed during follow-up. DISCUSSION: THs are usually slowly growing tumors with similar incidence in both sexes. They occur through a wide age range, with a peak in the fifth and sixth decades. Distinctive features reminiscent of the normal thymus make the pathologic diagnosis of THs easy in most cases. Malignant behaviour is indicated by microscopic or macroscopic invasion of the tumor capsule or surrounding organs or by the presence of metastases. Although there is no standardized staging system for thymoma, the one proposed by Masaoka is commonly employed. Total thymectomy is the procedure of choice, even for encapsulated tumors, with carefully exploration of the mediastinum for evidence of ectopic thymic tissue or local invasion. CONCLUSIONS: Despite an indolent course and a cytologically bland appearance, all thymic tumors can manifest a malignant behavior. Surgery continues to be the mainstay of treatment, and the ability to achieve complete resection seems to be the most important prognostic factor. Multimodality treatment involving postoperative chemotherapy and radiotherapy appears to increase the rate of complete resection and improves survival in advanced THs.

Bilateral lung and liver hydatid cysts. Case report.

Introduction. Synchronous occurrence of pulmonary and hepatic hydatid cysts is an uncommon manifestation of hydatid disease that is observed in less than 10% of cases. We report a rare case of bilateral lung (with bronchial fistula) and liver cyst, surgically treated after medical therapy. Case report. A 44-year-old housewife reporting fever, anorexia and fatigue that had been present for the previous 20 days received diagnosis of bilateral lung and liver hydatid cyst. Because of the dimensions of right lung cyst and the successive bronchial fistolization, we proceeded to three-stage operation of two thoracotomies and a laparotomy to control the risk of further rupture. After surgery, all post-operatives were uneventful. Complete resolution of the therapy with no evidence of recurrence at 2 years follow-up. Conclusion. We emphasize the need to search for additional hydatids in patients who present with either pulmonary or liver hydatids. The simultaneous treatment of liver and lung should be reserved to patients in good conditions; in all other cases, especially when one cyst is more symptomatic than the others or has more risk of rupture, we prefer to treat single cyst.

Neck node dissection in thyroid cancer. A review.

INTRODUCTION: thyroid cancer recurs most commonly in one or more cervical lymph nodes. Surgical treatment for differentiated or medullary thyroid carcinoma consists of total thyroidectomy (TT). The aim is to elucidate the potential benefits and drawbacks of neck dissection TT related. MATERIALS AND METHODS: differences between therapeutic and prophylactic neck dissection were analysed to prevent post-operative morbidity, neck recurrences and improve survival. DISCUSSION: there is considerable controversy regarding the treatment of patients with cervical node metastases specially in differentiated thyroid cancer. Considering that a neck dissection might help to reduce local recurrence, especially in medullary carcinoma, controversial remains regarding the modality and extension of cervical dissection. There are several surgical strategies to cervical lymphadenectomy as a prophylactic node dissection or a dissection only in symptomatic patients or the "node-picking" technique for selective lymphadenectomy or sentinel node biopsy. So it is possible to employ several kind of neck-node compartment related dissection. The risk of iatrogenic lesion during neck dissection is relatively high specially for nerve structures (i.e.: recurrent laryngeal nerve or spinal accessory nerve), so an experienced surgeon must mind the risk is higher during a re-operation in an anatomical subverted region. CONCLUSIONS: the extent of dissection and the experience of the surgeon both play important roles in determining the risk of surgical complications and recurrence. The decision to add neck dissection to total thyroidectomy weighed against documented benefits and risks. Injuries may also occur as a result of inadequate technique or as a result of poor expertise of the surgeon. We believe that deep knowledge of the thyroid region's surgical anatomy is necessary to realize a skilled and careful surgery of the neck.

Herpes simplex esophagitis in immunocompetent host: a case report.

Introduction. Herpes simplex esophagitis is well recognized in immunosuppressed subjects, but it is infrequent in immunocompetent patients. We present a case of HSE in a 53-year-old healthy man. Materials and Methods. The patient was admitted with dysphagia, odynophagia, and retrosternal chest pain. An esophagogastroduodenoscopy revealed minute erosive area in distal esophagus and biopsies confirmed esophagitis and findings characteristic of Herpes Simplex Virus infection. Results. The patients was treated with high dose of protonpump inhibitor, sucralfate, and acyclovir, orally, with rapid resolution of symptoms. Discussion. HSV type I is the second most common cause of infectious esophagitis. The majority of symptomatic immunocompetent patients with HSE will present with an acute onset of esophagitis. Endoscopic biopsies from the ulcer edges should be obtained for both histopathology and viral culture. In immunocompetent host, HSE is generally a self-limited condition. Conclusions. HSE should be suspected in case of esophagitis without evident cause, even if the patient is immunocompetent. When the diagnosis of HSE is confirmed, careful history and assessment for an immune disorder such as HIV infection is crucial, to look for underlying immune deficiency.

[Complications of elective esophago-gastro-duodenoscopy (EGDS). Personal experience and literature review]. / Le complicanze della esofagogastroduodenoscopia (egds) in elezione. Esperienza personale e revisione della letteratura.

INTRODUCTION: Although upper gastrointestinal (GI) endoscopy is reasonably safe, it is not perfectly so. The complication rate is about 0.1% for EGDS. Aim of this study is to schedule and evaluate all possible complications, starting from personal experience in Operative Unit of Surgical Endoscopy. PATIENTS AND METHODS: We evaluated all EGDS performed at the Operative Unit of Surgical Endoscopy of Policlinico in Palermo between January 2000 and January 2008. A single staff of endoscopists performed diagnostic and therapeutic exam. All complications were tabulated and scheduled to identify possible risk factors or indicators procedure- or patient-related. RESULTS: 5.258 patients (43.6 %) experienced temporary and self-limiting hypoxia (SaO2 < 85%); we report totally 18 complications (0.15%), according to literature data: 2 hypopharinx perforations (0.016%), 2 middle esophagus perforation (either with death of patients = 0.016%), 3 post-biopsy hematomas of the gastric wall (0.02%) and 2 duodenal wall (0.016%) 6 (0.04%) post-polypectomy bleeding, 1 abscess post-percutaneous endoscopic gastrostomy (PEG) (0.008%) and 1 accidentally PEG remove (0.008%). DISCUSSION: EGDS-related complications may occur and cannot be prevented completely even in expert hands however, early recognition and proper management will lead to better outcome. Because of the complexity of endoscopic procedures has increased, endoscopists need to be aware of all possible procedure-related complications and should use strategies to minimize it. CONCLUSIONS: Endoscopic complications will inevitably occur if an endoscopist does many procedures. The knowledge of potential complications and their expected frequency can lead to improved risk-benefit analysis by physicians and patients as well as true informed consent by patients. Early recognition of complications and prompt intervention may minimize patient morbidity.

The importance of pyramidal lobe in thyroid surgery.

INTRODUCTION: Pyramidal lobe (PL) is an embryological remnant of the thyro-glossal duct; its incidence varies from 15% to 75% but data concerning its size are lacking and limited to autoptic and radiologic evidences. Aim of our study is to elucidate the intraoperative frequency, location and surgical management of the PL. PATIENTS AND METHODS: 604 total thyroidectomy were performed between 1999 and 2007 in Unit of General and Thoracic Surgery of the University Policlinico of Palermo. The intraoperative incidence of PL was 12% (57% male, 43% female, mean age 42.5 years), but only about 50% were identified preoperatively with ultrasonography (US) (4% false positive) or with Tc-99m pertechnetate scintigraphy (8% false positive). RESULTS: In 77% of cases the lobe was affected by nodular pathology in multinodular goiter, in 1.3% by papillary cancer; in the rest of cases was normal. PL branched off more frequently from the left part of the isthmus (96%) than from the right part (4%) and in 25% of cases was associated with delphian lymph node. No PL exceeded 2 cm in length in pathologic specimen. There was no difference in thyroidectomy operative time with or without PL. At US, scintigraphic and laboratory follow-up (2 months-8 years), no incomplete resection of the gland due to the presence of PL were recorded. DISCUSSION: In anatomical studies the frequency of the PL is between 15% and 75%; PL is in 10-17% of normal subject and in 43% of patients with multinodular goiter. The PL is of great importance to the thyroid surgeon during thyroidectomy: it is crucial to look for, identify, and remove the PL, as this can be a cause of incomplete resection of the gland. If left behind in a patient who will require postoperative radioactive iodine, its presence will virtually nullify the anticipated benefit of I131 by absorbing most of the radioactive material; may exist relapse of cancer from PL left in situ. CONCLUSIONS: The intraoperative frequence of PL is 12%, and it is considered a normal component of the thyroid. Scintigraphic visualization of the PL depends on the kind of thyroid disorder and on the experience of radiologist, so the PL can often not be diagnosed by scintigraphic imaging. Finally, the whole anterior cervical region has to be investigated very carefully during thyropidectomy not to overlook a long or thin pyramidal lobe or other ectopic thyroid tissue because actually doesn't exist the goldstandard preoperative method to diagnoses PL.

[Thoracentesis and pleurodesis in the treatment of pleural effusion. Personal experience]. / Toracentesi e pleurodesi nel trattamento dei versamenti pleurici. Esperienza personale.

AIM: The pleural effusion is a sign of pulmonary, pleural or extrapulmonary, benign or malignant pathology. Our aim is to bring our experience on the treatment of the malignant pleural effusion through thoracentesis and successive pleurodesis. PATIENTS AND METHODS: From January 2000 to January 2007 we performed 217 thoracentesis of which 123 (57%) in subjects with malignant pleural effusion. In 92 of 123 subjects (75%) we performed a drainage with small size thoracic tube to realize directly the pleurodesis with sterile des-asbestos talc. RESULTS: None complication was registered during and after thoracentesis and pleurodesis and no mortality was recorded. We usually used talc slurry technique. Relapse rate after first treatment was of 12.2%. CONCLUSIONS: The pleural effusion is a pathological condition that usually needs repeated operative procedures with serious danger for the patient, however without definitive results. On the basis of our experience and considering the characteristics of sclerosing agents, we conclude that the sure, effective and economic agent for the pleurodesis is the des-asbestos talc.

What to do when endoscopic retrograde cholangio-pancreatography fails? Personal experience.

BACKGROUND: Endoscopic retrograde cholangio pancreatography failure is a rare and some dramatic reality too for the management of bilio-pancreatic tract disorders and in these cases it needs to utilize others operative technique. PATIENTS AND METHODS: Over a 6-year period, a total of 757 ERCPs were performed. In seventeen of these ERCPs the standard endoscopic technique failed and we employed alternative techniques such as interventional radiology or surgical management or double endoscopic approach. RESULTS: In all 17 failed ERCPs the alternative procedures allowed us to success in bilio-pancreatic disease. CONCLUSION: ERCP is an operator-dependent procedure. Even in expert hands failure occurs in 3% to 10% of cases. ERCP failure doesn't be considerated a dramatic situation in the management of the bilio-pancreatic disease for a multidisciplinary team (endoscopist, surgeon and interventional radiologist) whose cooperation allows to success.

[Surgical management of medullary thyroid carcinoma. Personal experience]. / Trattamento chirurgico del carcinoma midollare della tiroide. Esperienza personale.

INTRODUCTION: Medullary Thyroid Carcinoma (MTC) is a rare malignancy of the parafollicular C cells of the thyroid gland. Aim of our study is reporting retrospective analysis of our experience about the surgical treatment of MTC, especially pointing on lymphadenectomy. PATIENTS AND METHODS: from January 2000 to March 2006, were performed 546 thyroidectomy, 6 of them for MTC (1.09%): 5 sporadic and 1 familiar. All the patients were operated with standard technique (total thyroidectomy) and submitted to endocrinologic and instrumental follow-up. RESULTS: in our experience, we do not registered early or late complications as bleeding, laryngeal nerves lesions and parathyroid lesions or intra-postoperative deaths. DISCUSSION: MTC occurs sporadically or as part of the multiple endocrine neoplasia type 2 (MEN 2 a/b) syndromes in patients who have inherited a mutation in the RET proto-oncogene. The diagnosis is made by fine needle aspiration biopsy (FNAB) and by measuring calcitonin levels in the blood. Primary treatment consists of surgical resection including a total thyroidectomy, central neck nodal dissection and functional lateral neck nodal dissections. Most patients with a palpable primary tumour have nodal disease at the time of operation, and nodal involvement is often bilateral. CONCLUSIONS: adequate resection of the primary tumour and cervical lymph nodes is important to optimize outcome and minimize the risk of recurrent disease. Following primary surgical resection, more than 50% of the patients will have recurrent disease with persistent elevation of calcitonin levels. Currently, there is no adequate systemic therapy for recurrent disease. Surgical reoperation or conservative observation are the best available options.

[Clavicle fracture complicated by pneumothorax. Case report and literature review]. / Pneumotorace da frattura del terzo laterale della clavivola. Caso clinico e revisione della letteratura.

INTRODUCTION: the clavicle is one of the most commonly fractured bones, accounting for up to 4-10% of all adult's fractures. These fractures are comparatively easy to manage and typically heal with routine immobilisation. CASE REPORT: a 28 year old man had direct driving trauma to the left shoulder and reported a displaced fracture of the third lateral of left clavicle and an apical pneumothorax. The pneumothorax was treated by the insertion of a chest drain under local anaesthesia. The chest drain was removed 12 days after the injury and the patient was transferred in Traumatology for specific therapy. RESULT: 6 months after the accident, the clavicular fracture had united and the chest radiograph and CT were normal. DISCUSSION: most clavicular fractures result from a fall or a trauma on ipsilateral shoulder. However, the incidence of complications associated with isolated clavicle fracture, including vascular, brachial plexus, and penumothorax, are low but potentially serious. CONCLUSION: careful history and physical examination with particular attention to the neurovascular and chest examination are vital. Close inspection of the radiographs for such potential complication are mandatory in all clavicular fractures and cannot be overstated. From the analysis of international literature, we can affirm that thoracostomy and immobilization are effective to heal pneumothorax and clavicle fracture.

Unusual acute onset of pedunculated extragastric leiomyosarcoma. Case report.

INTRODUCTION: A case report of 25 yrs-old man with pedunculated exogastric leiomyosarcoma (with acute onset) surgically treated is presented. CASE REPORT: The patient was operated after clinical, instrumental and blood sample tests. We performed a 5 cm wedge resection of the stomach in continuity with the omentum. Careful inspection revealed neither adenopathy nor metastases. RESULTS: Actual complete remission of pathology. Negative 1 year follow up by endoscopy and CT. DISCUSSION: Information on gastric leiomyosarcoma (LM), such as prognostic factors, patterns of disease recurrence, and optimal methods of treatment, are derived from limited clinical experience. Although about 25% of the gastric mesenchymal tumors present an exogastric growth, pedunculated exogastric leiomyosarcomas are extremely rare. Lymphatic spread of gastric LM is uncommon, therefore a formal lymph node dissection is not standard surgical management. At present, there is no evidence of intraperitoneal seeding from exogastric leiomyosarcomas. Consequently, a local resection with an adequate margin is sufficient when no invasion to the adjacent structures is observed. Neither the addition of lymphadenectomy nor the wider tumor-free margins of a radical gastrectomy seemed superior to the more conservative local excision. CONCLUSIONS: Further studies are called for to elucidate if exogastric tumours lead to peritoneal seeding and, thereby, affect tumour survival.

[Bowel preparation before colonoscopy: personal experience and brief literature review]. / La preparazione intestinale alla colonscopia. Esperienza personale e breve review della letteraura.

INTRODUCTION: Colonoscopy is the most commonly used technique for inspection of the colonic mucosa. The safety and effectiveness of colonoscopy in identifying important colonic pathology is directly impacted by the operator experience and by the quality of the bowel preparation performed in anticipation of the procedure. PATIENTS AND METHODS: From December 2000 to June 2006, we performed 8328 total colonoscopy (M:F ratio =1:1.8, mean age 54.7 years, range 16-93). All the patients were submitted to routinary bowel preparation with polyethylenglycol (PEG) the evening before the exam, with fibres diet restriction 5 days before the exam. RESULTS: On 8328 colonoscopy, 1243 were not actable for worst/absent intestinal toilette. 423 colonoscopy were completed after visceral washing with saline solution during the exam. On 1243 colonoscopy repeated, 852 were in subjects affected by diabetes (p < 0.05); in these patients we prescribed 5 litres solution of PEG one day before the endoscopy, diet without fibers 7 days before the exam and the use of 250 ml solution of PEG (bid): with these method, all the patients were submitted successfully to colonoscopy and retrograde ileoscopy. DISCUSSION: Physicians favor preparations associated with the best patient compliance to achieve the best results. Patients favour preparations that are low in volume, palatable, have easy to complete regimens, and are reimbursed by health insurance or are inexpensive. Both patients and physicians favor preparations that are safe to administer in light of existing comorbid conditions and those that will not interact with previously prescribed medications. CONCLUSIONS: Today doesn't exist the "gold standard" for bowel preparation before colonoscopy. Basing on our experience, the 4 litres PEG solution mentioned above is well tolerated and effective. In patients with severe comorbidity (diabetes, renal failure, high blood pressure) only little modifications are required to optimize the colon cleansing.

[Pull percutaneous endoscopic gastrostomy: personal experience]. / La gastrostomia percutanea endoscopica (PEG) metodo pull: nostra esperienza.

OBJECTIVE: To review the indications, complications, and outcomes of percutaneous endoscopic gastrostomy (PEG), that are placed routinely in patients unable to obtain adequate nutrition from oral feeding for swallowing disorders (neurological diseases, head and neck cancer, oesophageal cancer, psychological disorders). DESIGN: Retrospective review of patients referred for PEG placement from 2003 to 2005. SETTING: Endoscopic Surgery in Section of General and Thoracic Surgery, Faculty of Medicine and Surgery, Palermo, Italy. PATIENTS AND METHODS: A total of 50 patients, 11 women and 39 men, referred our Section for PEG placement. Indications for PEG placement included various neurologic impairment (82%), oesophageal non-operable cancer (6%), cardia non-operable cancer (4%), cerebrovascular accident (2%), anorexia (2%), pharyngeal esophageal obstruction (2%), head and neck cancer (2%). All patients received preoperative antibiotics as short-term profilaxis. RESULTS: 51 PEGs were positioned in 50 patients. No major complications were registered; 45 patients (90%) were alive at 1 year follow-up and no mortality procedure-related was registered. Percutaneous endoscopic gastrotomy removal had been performed on 2 patients as end-point of treatment, and 43 patients continued to have PEGs in use at 2006. CONCLUSIONS: Outpatients PEG placement using conscious sedation is a safe and effective method for providing enteral nutrition. This technique constitutes the gold standard treatment for enteral nutrition in patients with neurologic impairment or as prophylactic in patients affected by head and neck cancer who needs demolitive surgery. Patients should be carefully assessed, and discussion with the patient and their families should be held to determine that the patient is an appropriate candidate. The Authors feel prophylactic antibiotics lessened the incidence of cutaneous perigastrostomy infection.

[Total thyroidectomy of choice in papillary microcarcinoma]. / La tiroidectomia totale di principio nel microcarcinoma papillare.

INTRODUCTION: Today, the "gold standard" of surgical management of benign thyroid disease is still controversy. There are different surgical approaches to the thyroid gland, from a radical, total thyroidectomy to a conservative treatment, lobectomy with or not isthmectomy. In consideration of the more frequent incidence of small carcinomas accidentally founded in the context of the thyroid parenchyma removed for another pathology, the aim of this study is to bring a contribute to resolve the debate on the therapeutic choice in the surgical management of the thyroid benign disease. PATIENTS AND METHODS: From January 2000 to January 2006 502 thyroidectomy were performed in the Section of General and Thoracic Surgery of University of Palermo: 458 total thyroidectomy (91.3%), 2 partial thyroidectomy (0.3%), 24 (4.8%) lobectomy with isthmectomy and 18 (3.6%) reinterventions for relapse; 34 patients (6.8%) were preoperative suspected (cytological or ultrasonography) for thyroid cancer. RESULTS: After total thyroidectomy in 17 patients (3.4%) we founded a papillary incidental "microcarcinoma", diameter range 2-10 mm (mean 6.9 mm). In 2 cases (11.7%) we found infiltrative and multifocal tendency. Histologically, were 11 cases of classical papillary (64.7%), 4 cases (23.6%) of follicular and 2 (11.7%) sclerosing, in 9 cases of multinodular goiter, 3 of follicular adenoma, 3 cases of follicular carcinoma, 1 case of Graves disease and 1 case of Hashimoto thyroiditis. DISCUSSION: Papillary microcarcinoma is a "thyroid papillary cancer with a diameter < or = 1 cm?". From the analysis of literature, we observed a progressive increasing of papillary microcarcinoma from 12% (1980) to 25% (1990), with a prevalence of diameters < or = 5. Actually, there are no univocal data on natural history, nodal metastasis, biological and clinical behaviour, morbidity and mortality of these neoplasms; the certain data is that only the radical surgery can prevent relapse and incidentalomas that modify surgical approach. CONCLUSIONS: In our opinion, the surgical management of the all thyroid disease must be the more radical since the first time, because we think other approaches not correct to improve the complete health from the benign thyroid disease and to prevent (secondary prevention) papillary microcarcinoma not pre-operative diagnosed, because there are no preoperative pattern to make a correct diagnosis of this tumour.

[Endoscopic treatment of pancreatic pseudocysts]. / Il trattamento endoscopico delle pseudocisti pancreatiche.

AIM: the Authors report their experience about the endoscopic treatment of pancreatic pseudocysts (PP). PATIENTS AND METHODS: report of 10 cases; evaluation of effectiveness, morbidity and mortality of treatment. SETTING: Section of General and Thoracic Surgery, AOUP ?Paolo Giaccone?, University of Palermo. PROCEDURE: endoscopic drainage was performed in all 10 patients, with 2 cysto-gastrostomy, 5 cysto-duodenostomy and 3 trans-papillary cystic drainage. RESULTS: 100% successful; one case of bleeding post-procedure (10%), one case of sepsis (10%) and one case of stricture of fistula between PP and duodenum. CONCLUSION: endoscopic drainage of PP is a safe and simple treatment, with high rates of success and low rate of complication procedure-related, complementary to surgery.

[Prevention of complications in thyroid surgery recurrent laryngeal nerve injury personal experience on 313 cases]. / Prevenzione delle complicanze in chirurgia tiroidea: la lesione del nervo laringeo ricorrente. Esperienza personale su 313 casi.

INTRODUCTION: Thyroidectomy poses many challenges for the surgeon who undertakes endocrine surgery and iatrogenic injury of inferior laryngeal nerve (ILN) is one of the most serious (0-20%). We report our personal experience of a series of 313 thyroidectomy with intraoperative identification of ILN. METHODS: 313 patients (253 females, 60 males, whose age was between 17 and 86 years, mean 41 years) had undergone thyroidectomy in our Operative Unit from January 2000 to January 2004. Among them, 259 patients underwent total extracapsular thyroidectomy, 38 subtotal thyroidectomy, 5 isthmo-lobectomy and 11 were completions of thyroidectomy in patients who had previously undergone a first thyroid surgical intervention. RESULTS: We identified 588 ILN (in all cases), in the left or in the right side only in case of isthmo-lobectomy or completion of thyroidectomy. In two cases (0.63%) we noticed on the right side a non recurrent laryngeal nerve. Concerning the postoperative results we noticed only one case (0.38%) of ILN injury with monolateral vocal cord hypomotility and temporary dysphonia, actually on phoniatric therapy at follow-up. CONCLUSION: A strong knowledge of the anatomy and embryology of the thyroid region, a commitment to meticulous attention to detail, the awareness of the extremely varying course of the ILN and the inferior thyroid artery and their relations, and adequate experience are all required to maintain a level of expertise and avoid ILN. Thyroid carcinoma, recurrent goitre, total thyroidectomy operation, duration of the operation are factors which increase the risk of postoperative ILN injury.

[Non recurrent laryngeal nerve. Personal experience]. / Il nervo ricorrente che non ricorre. Esperienza personale.

PURPOSE: Damage to the recurrent laryngeal nerve (RLN) during thyroid or parathyroid surgery is the most common iatrogenic cause of vocal cord paralysis. Identification of the RLNs and meticulous surgical technique can significantly decrease the incidence of this complication. Nonrecurrent RLNs (NRRLNs) are exceedingly rare. Surgeons need to be aware of their position to avoid injuries. PATIENT AND METHODS: A retrospective review of 263 right RLN exposures (and 251 left RNL) over a 5-year period was performed. RESULTS: Two NRRLNs were encountered, for an incidence of 0.39% (0.76% only for right dissection), without anatomic anomalies on the left side. The nerve anomaly was never preoperatively diagnosed. CONCLUSION: NRRLNs are rare and is associated with a right subclavian artery arising from distal aortic arch. Awareness of their existence and correct surgical technique will prevent the surgeon from accidentally lesion of NRRLN one if it is encountered during thyroid or parathyroid surgery.

[Intestinal endometriosis: an obscure cause of cyclic rectal bleeding]. / Endometriosi intestinale: una causa oscura di rettorragia ciclica.

OBJECTIVE: Authors report their experience about a case of intestinal endometriosis that lead cyclic and recurrent rectal bleeding in a fertile-age woman. DESIGN: Report of 1 case with multidisciplinary approach and surgical treatment. Surgical effectiveness evaluation and 2 years follow-up. Brief review on the recent literature and the diagnostic and therapeutic implications. SETTING: Section of General and Thoracic Surgery, Department of General Surgery, Emergency and Organ Transplantation, Policlinico "Paolo Giaccone", Palermo. INTERVENTION: After correct and sure diagnosis, the patient was submitted to sigmoid segmental resection with radical and curative intention. RESULTS: Complete recovery. Follow-up (24 months) negative. CONCLUSIONS: Diagnosis of endometriosis should be considered in women with recurrent monthly abdominal pain and bowel symptoms, especially if accompanied by gynaecologic complaints, even because the significant symptoms overlap with the irritable bowel syndrome (IBS) and makes the differentiation extremely difficult. Treatment of GI endometriosis is best approached in collaboration between gynaecologist experienced and intestinal surgeon. The high accuracy and low complications suggested that EUS-FNA was effective for the correct histologic diagnosis of intestinal endometriosis.

[Regression of primary low-grade gastric mucosa-associated lymphoma by eradication of Helicobacter pylori infection: case report]. / Regressione di un maltoma gastrico primitivo attraverso l'eradicazione della infezione da HP: report di un caso.

OBJECTIVE: The Authors report their experience in diagnosis and treatment of one case of primary low-grade gastric lymphoma of mucosa associated lymphoid tissue (MALT); recent international literature review. EXPERIMENTAL DESIGN: Complete clinical report. Diagnostic, clinical and prognostic indication, evaluation of effectiveness of eradication therapy and short follow-up. SETTING: Operative Unit of General and Thoracic Surgery. University "Paolo Giaccone" of Palermo. INTERVENTION: Treatment of H. Pylori infection (lansoprazole, amoxicillin and metronidazole twice a day for 14 days; after that, lansoprazole for another 4 weeks), according to international guide-lines. RESULTS: H. Pylori was completed eradicated. Disappearance and total regression of the lymphomatous tissue was observed. No relapse were recorded at short follow-up. CONCLUSIONS: Our reports confirm the recent anecdotal reports on regression of gastric MALT lymphoma after eradication of H. Pylori and indicates that the growth of these extranodal lymphomas may depend on H. Pylori.

[Gastric foreign body: bezoars. Apropos of two cases]. / Corpi estranei gastrici: i bezoari. A proposito di due casi.

OBJECTIVE: The authors report their experience about the treatment of two cases of gastric bezoar, treated in curative mode, the first endoscopically and the second with surgical intervention. SETTING: Operative Unit of General and Thoracic Surgery, Department of General and Emergency Surgery, Organ Transplantation, Policlinico, University of Palermo. INTERVENTION: The patients were submitted to curative treatment, one with endoscopic treatment (mechanical fragmentation of phytobezoar and fragments extraction via-overtube), the second with surgical gastrotomy (stamp trichobezoar). There were no procedure-related complications. RESULTS: The two patients were curative and radically treated. Negative 2 years follow-up. CONCLUSIONS: There is no standardized method for the treatment of gastric bezoars. Endoscopic removal of gastric bezoars after fragmentation and using overtube is effective and safe. Surgical intervention, equally safe, is reserved to huge, stamp, impacted or complicated bezoars.
