Giant fibrovascular polyp of the esophagus.

Giant fibrovascular polyps are uncommon benign esophageal tumors almost always originating from the cervical esophagus, frequently from the upper esophageal sphincter. The case of a 74-year-old man with a long history of dysphagia and a weight loss of 9 kg is presented. Neither barium esophagogram, computed tomogram or magnetic resonance imaging correctly evidenced the lesion. Only fiberoptic endoscopy suggested the correct diagnosis because the mass fluctuated endoluminally with the spasm of vomiting. A left cervical exploratory incision with esophagotomy was performed following the experience of two previous similar cases. A giant fibrovascular polyp was observed and excised. If a malignant or benign extensive intramural tumor had been identified, a total esophagectomy would have been performed. In our opinion the possibility of the presence of a fibrovascular polyp should always be considered in the presence of an undetermined esophageal mass, and in these cases a left cervical incision is the preferred surgical access. Once the correct diagnosis is established, a major esophageal resection should always be avoided.

[The choice of surgical therapy in adenocarcinoma of the cardia]. / La scelta della terapia chirurgica nell'adenocarcinoma del cardias.

AIM: From 1996 the adenocarcinoma of the esophago-gastric junction (AEG) is divided into 3 types according to Siewert's classification. For AEG type I and III the surgical treatment is codified, while for type II is still controversial. The aim of our study is to understand what is the better surgical treatment for AEG type II. METHODS: From 1990 to 2002 we have performed 111 resections for adenocarcinoma of the cardia: 25 for AEG type I (all esophago-gastric resection), 39 for type II (22 esophago-gastric resection, 17 extended total gastrectomy with esophageal resection) and 47 for type III (8 esophago-gastric resection, 39 extended total gastrectomy with esophageal resection). RESULTS: The morbidity and mortality rates are 17 and 5.4%, without significant difference between the different surgical treatment (p>0.01). The 5 year survival rate is 35%. Significant prognostic factors are the staging TNM (p=0.002) and principally the presence of metastatic lymph nodes (p=0.001). For AEG type II any significant difference in survival is associated with surgical strategy, also in early stage (p>0.01). CONCLUSIONS: According to the results of our study and those of the other authors, who have showed that a 10 cm distance of the neoplasm by the gastric side and the esophageal one could assure oncologic radicality and also that metastatic lymph nodes below pylorus and near greater curvature are uncommon, we can consider esophago-gastric resection for AEG II a speedy, safe and oncologically correct surgical treatment.

Acute hyperparathyroidism: our experience with 36 cases.

OBJECTIVES: Acute hypercalcemia is a serious condition and represents a physician-surgical emergency: the difficulty in setting a precise diagnosis is due to several possibilities that can cause the condition. It is our purpose to critically evaluate the most actual schemes of treatment and the conditions that could favour the appearance of a hypercalcemic acute crisis. MATERIALS AND METHODS: A retrospective study was performed considering 1321 patients (638 primary HPT, 683 secondary or tertiary HPT) operated from 1975 to December 2002 for Primary, Secondary and Tertiary HPT. RESULTS: It should be noticed that out of 638 cases of Primary HPT this syndrome was present in 35 patients (Ca higher than 15 mg/dl): if you compare these cases with the hyperparathyroid population with calcium less than 15 mg/dl it is possible to observe that a double adenoma or a carcinoma were more frequently found in acute HPT, as the cystic appearance of the lesion. The weight of the adenoma and the PTH assay are strictly correlated with the appearance of this syndrome. The mortality rate is also higher (2.8% to 0.1%) than in the hyperparathyroid patient who underwent parathyroidectomy without hypercalcemic crisis. CONCLUSION: These characteristics suggest that an early operation is mandatory in the patients in whom such a possibility could be expected, before serious involvement of the cardiovascular, renal or neuromuscular system. We can point out the rarity of this syndrome in Secondary and Tertiary HPT: just one case in Secondary out of 683 patients operated on from 1975 until December 2002.

[Adenocarcinoma of the cardia: surgical strategies compared]. / Adenocarcinoma del cardias: strategie chirurgiche a confronto.

BACKGROUND: The incidence of adenocarcinoma of the cardia is increasing. The choice of surgical strategy for AEG type II of Siewert classification is the subjects of controversial discussion. The aim of our retrospective study is to analyse the surgical results in 12 years. MATERIAL AND METHODS: Since 1990 to 2002, 111 patients underwent resection for adenocarcinoma of the cardia at III Division of General Surgery, University of Turin. Twenty-five patients had AEG type I, 39 had type II and 47 type III. Transthoracic or transhiatal oesophagectomy with resection of the proximal stomach were performed in 55 cases and extended total gastrectomy with transthoracic or transhiatal oesophagectomy in 56. RESULTS: The morbidity and mortality rates are 17% and 5.4%. The 5 years survival rate is poor (35%) for all Siewert type. Survival is significantly associated with stage and the presence of lymph node metastasis, but not correlated with Siewert classification and surgical approach. Also in the AEG II the survival is not modified by the surgical approach. CONCLUSION: In patient with AEG I the therapy of choice is a radical transthoracic or transhiatal oesophagectomy with resection of the proximal stomach. For type III extended total gastrectomy with transthoracic or transhiatal oesophagectomy is the procedure of choice. The superiority of the thoracoabdominal approach is therefore evident in terms of oncologic radicality. Survival is similar in AEG type II patients for both operations. A oesophagectomy with proximal gastric resection should be adopted for these tumors as the standard procedure in the majority of cases.

[Continuous brachial plexus blockade for shoulder surgery]. / Il blocco continuo del plesso brachiale per la chirurgia della spalla.

Continuous brachial plexus block is the technique of choice for postoperative shoulder pain treatment. The localization of the plexus is usually obtained drawing landmarks on the skin and using the electrical nerve stimulator; these and other different modalities are applied in order to reach safely and precisely nerve roots to be blocked with an anaesthetic solution. The Author presents a new anatomical perspective to guide the localization of the brachial plexus. It is shown how it is possible to detect the pathway of the brachial plexus from the cutaneous surface, linking between each other various landmarks: a) the apex of the scalene triangle, at the cross of a line leaving from the cricoid process and directed posterior to the posterior border of the sternocleidomastoid muscle, b) the midline of the clavicle c)the deltoid-pectoral sulcus d) the midpoint between the coracoid process and the chest profile e) the pulsation of the artery in the axylla. Following the guide of the so formed anesthetic line, is possible to place the needle, with a direction from distal to proximal, in a tangential route towards the interscalenic groove, thus allowing to perform a block of the plexus in a simple and efficacious way.

[Two in one block for carotid surgery]. / Blocco 2 in per la chirurgia della carotide.

The choose of the best anaesthesia for carotid surgery is a very debated item: the locoregional techniques probably offer more hemodynamic stability and a direct neurologic monitoring, while general anaesthesia allows the complete control of airways and ventilation and reduces the global stress for the patient. This review analyzes the data of studies that compare general and locoregional anaesthesia. Among the latter, possibly elective techniques, the one described by Winnie combines an optimal analgesic efficacy with the lowest rate of adverse effects. A single bolus of a local anesthetic injected at a C4 level (apex of scalene muscles triangle) guarantees a complete block of the superficial and deep cervical plexuses.

[Cervical mechanical anastomosis by transhiatal approach with a new circular stapler, Ehicon ECS 21]. / Anastomosi meccanica cervicale per via transiatale con una nuova suturatrice circolare, Ethicon ECS 21.

Authors describe a new technique of mechanical cervical anastomosis using a new, particularly long, stapler, the ECS Ethicon. Mechanical anastomosis at neck level is difficult to perform with stapler now in use, so manual anastomosis is usually preferred. However the percentage of leakage is relatively high. The possibility of doing a mechanical anastomosis introducing the stapler through the pylorus is described. At the moment cases are too few to give a full evaluation of this new technique, but certainly it could be a valid alternative, safer and quicker, to manual anastomosis.

[The combined radiochemotherapy of inoperable esophageal neoplasms: a feasibility study]. / Radio-chemioterapia combinata delle neoplasie esofagee inoperabili: studio di fattibilità.

January, 1994, through January, 1995, eighteen patients (17 men; median age: 59.9, range: 32-73) with biopsy-proved squamous cell carcinoma (n = 15), adenocarcinoma (n = 2) or undifferentiated carcinoma (n = 1) of the esophagus were treated with concurrent chemo-radiotherapy. All patients had inoperable lesions for unresectable disease (11 patients) or concomitant illness (7 patients); median Karnofsky score was 70 (range: 60-80). According to the 1988 American Joint Committee on Cancer Staging system, one patient was graded as Stage IIA (T2N0 + oropharyngeal cancer T4N1), two Stage IIB (T2N1), twelve Stage III (8 T3N1, 1 T4N0, 3 T4N1) and three Stage IV (2 T3N0M1, 1 T4N0M1). Treatment consisted of two courses of chemotherapy by cisplatin (75 mg/m2 i.v. on days 1 and 29) and 5-FU (1000 mg/m2/24 hours by continuous infusion from days 1 to 4 and from days 29 to 32) along with one course of concomitant radiotherapy at 45 Gy (1.8 Gy per fraction, one fraction per day and 5 fractions a week). After 15-30 days, the patients were treated with a boost dose of 7 Gy by high-dose-rate intraluminal brachytherapy. All patients are assessable for toxicity and seventeen for response. The combined treatment was generally well tolerated, with only one case of WHO grade III toxicity (thrombocytopenia). Eight of the eighteen patients had a complete response (47%); four a partial response (24%); four a minimal response (24%) and one showed stable disease (5%). Only one patient developed local progression, and four distant metastases. All the eight patients with CR are alive without local recurrence (two distant metastases) with a mean follow-up of 6 months. This treatment regimen provides good local tumor resolution with no major toxicity. The value of this study protocol will be determined by the rate of long-term survivors.
