[Surgical therapy of gastro-esophageal reflux (clinical contribution)].

The Authors, on the basis of 119 cases of gastroesophageal reflux, submitted to intervention at the Surgical Department of Verona from 1970 up to 1983, seize this opportunity for some remarks about the problem: in fact, its physiopathology is still discussed, and numerous were the surgical techniques suggested for its treatment. 56 patients, treated according to Nissen-Rossetti's technique, and 16, in whom the antireflux plastic operation was complemented by a selected proximal vagotomy with pyloroplastics, were remote-checked. The good results got till now mean the SPV + P can be usefully associated to the antireflux plastics for hiatal hernia.

[Traumatic rupture of the diaphragm. Diagnostic problems and surgical therapy].

The Authors show 10 cases of traumatic disruption of diaphragm, subsequent to close or open trauma, all subjected to urgency operation. They discuss the problems concerning diagnosis and surgical tactics, and point out the frequency of visceral and osseous associated lesions and their importance in conditioning prognosis.

[Delayed recognition of traumatic rupture of the diaphragm. Diagnostic and therapeutic problems].

The Authors face the diagnostic and therapeutical problems involved in the tardy recognition of diaphragmatic breakages. On the basis of two clinical cases observed, they emphasize the relative frequency of this lesion, the variability of the clinical pictures, the limits of the clinical and radiological diagnostics, the utmost seriousness of the complications. They face the problem of the choice of the surgical way of approach and the techniques for repairing the diaphragmatic lacerations.

[Multivariate statistical analysis in predicting bronchopulmonary complications after surgical interventions in cancer of the lung].

A multivaried statistic process, the linear discriminant analysis, applied to VEMS, CV, I.T., FEF 25-75, pH, PaO2, PaCO2, was used by the authors to foresee, in 42 patients suffering from bronchogenous carcinoma, the arising or absence of respiratory complications after operation. With such method, the falsely positive or negative previsions, resulted to be 13 with a total percentage of error as high as 30%. These results suggest that, even when elaborated through the multivaried analysis, the parameters studied do not allow to adequately discriminate the patients who would develop, after operation, bronchopulmonary complications from those who would be exent from them.

[Endobronchial lipomas].

The authors report three cases of endobronchial lipoma, and study the etiopathogenesis and the main clinical and therapeutical aspects of such neoplasiae. Both diagnosis and treatment should be timely, in order to prevent irreversible damages to lung parenchyma, compelling surgeons to mutilating operations making the function of the apparatus heavier.

[Our experience with selective proximal vagotomy].

The authors show a casuistry of 125 operations of SPV, and comment on the clinical and physiopathologic presuppositions justifying the indications to SPV in the field of gastroduodenal peptic pathology. They report the results of the gastric probings, both basal and after stimulation with pentagastrin in the pre- and postoperative phase, and after a year. They face the problem of pyloroplastics, and appraise the elements indicating and contra-indicating it in association to SPV.

[Long-term survival of patients operated on for carcinoma of the lung (author's transl)].

The long-term fate of patients treated surgically for carcinoma of the lung is not well known. In a careful review of the literature the authors found only nine papers with a postoperative followup of at least 10 years; the mean survival was 16,3% of patients so treated. Factors making for a good long-term prognosis include small initial tumor size, absence of mediastinal lymph node invasion, a favorable histologica type, and the type of surgery performed (partial exeresis). Translated into TNM code, this means that the best candidates for prolonged survival are patients with lung carcinoma of the squamous cell type, stage I, treated by limited lung exeresis.

[Palliative treatment of esophageal cancer].

The AA. describe the indications, the technique and the complications of application of oesophageal endoprosthesis (Celestin or Haring) for palliative treatment of oesophageal cancer and they value the results of 34 applications of these prosthesis that were executed about Surgical Clinic in Verona with satisfactory results during the period 1974-77. They show the improvement of survival conditions in these patients, the rareness of complications, the absence of absolute contra-indications.

[Oncocytoma of the lung: presentation of 1 case (author's transl)].

The Authors describe one case of pulmonary oncocytoma successfully treated by ablative surgery. The patient was a man aged 38 with an asymptomatic nodule, about the size of a walnut, in his right lower lobe. The whole right lower lobe was removes surgically, and histological examination resulted i na diagnosis of pulmonary oncocytoma. In the discussion, the authors point out that this type of malignancy is extremely rare, with only 7 cases reported in the more recent literature to the best of their knowledge.

[Cancer of the gastric stump (author's transl)].

On the evidence of 24 cases of cancer of the gastric stump the authors discuss the real incidence of this dread complication; they conclude that starting 8 years after primary surgery, all patients carrying a gastric stump must be regarded as high-risk subjects for malignancy; further, they recommend that pyloro-gastrectomy after Billroth (II) be considered for execution in young patients with all possible reluctance.

[Complications of lung surgery in the aged: relapsing postresection atelectasis (author's transl)].

The authors describe one case of relapsing postoperative atelectasis occurring with considerable severity after an upper left lobectomy for malignancy in a man of 68. Said complication recurred no fewer than six times during a hospital stay of 44 days and constituted a major threat to the good outcome of surgery. The patient was finally discharged in good conditions, and a later recheck revealed no important alterations in the surviving lower left lobe.

[Perforation of the esophagus during pneumatic dilatation in achalasia].

Esophageal perforation is a serious complication of pneumatic dilatation. We studied the cases of 4 patients (2 men and 2 women, mean age 58 years, range 56-62) who had surgical treatment for achalasia, two of which had had previous dilatation. The main symptoms were pain and dyspnea. Pneumomediastinum was present in all patients, pleural effusion in 2 and cervical emphysema in 1. Esophagographic results showed evidence of perforation in all four cases and gastric patches were surgically placed on the esophageal tear within 12 hours. Three patients received enteral nutrition for an average of 13 days. Mean hospital stay was 14 days. No post-operative complications were exhibited although one patient did develop gastroesophageal reflux 3 months later and underwent surgery to repair a hernia in the thorax 5 years later. Early and aggressive treatment is considered the best therapy and the gastric patch, in our opinion, is an effective and reliable technique for esophageal perforation repair in achalasia patients.

Strangulated traumatic hernia of the diaphragm. A report of two cases.

The herniation of abdominal viscera in the thorax can immediately follow diaphragmatic rupture or be delayed even years after the injury. The herniated viscera can strangulate; this consequence may lead to a dangerous misdiagnosis which could be lethal for the patient. Radiological procedures, serial chest X-ray studies, CT and MRI scans are mandatory to confirm diagnosis. The insertion of a naso-gastric tube is a very helpful method in ruling out hypertensive pneumothorax in the presence of an air-fluid level in the thorax. We report 2 cases of strangulated traumatic hernia of the diaphragm occurring just a few hours (case 1) and 18 months (case 2) after the trauma. During thoracotomy, a rupture of the left diaphragmatic cupola was demonstrated with herniation of the stomach in case 1, the stomach, spleen and transverse colon in case 2. No postoperative mortality or morbidity were detected.

Non ductal-adenocarcinoma neoplasms of the pancreas.

Pancreatic Non Ductal-Adenocarcinoma Neoplasms (PNDAN) represent about 20% of pancreatic and periampullary tumors and should be considered in differential diagnosis with ductal adenocarcinoma in the presence of isolated pancreatic mass. From January 1992 to December 1998, 238 patients were operated on for pancreatic and periampullary masses. Fifty-five patients had PNDAN: 24 endocrine tumors, 7 serous cystadenomas, 6 intraductal papillary-mucinous tumors, 5 acinar carcinomas, 4 mucinous cystadenomas, 3 metastatic tumors, 2 cystic papillary tumors, 2 solid cystadenocarcinomas, 1 neurilemmoma, and 1 pancreatoblastoma; 19 were benign and 36 were malignant or borderline tumors. A correct preoperative diagnosis was obtained in 58% of the cases. In all other cases, diagnosis was achieved intraoperatively. Major (18 pancreaticoduodenectomies, 17 left splenopancreatectomies, 1 total pancreatectomy) and minor resections (5 central pancreatectomy, 10 enucleations) were performed; curative surgical operations were carried out on 39/55 patients (curative resectability: 71%). Operative mortality and morbidity were 1.8% and 21.8%, respectively. Three and 5-year actuarial survival for malignant or borderline PNDANs are 65% and 40% versus 31% (3-year) for ductal adenocarcinoma of pancreatic head treated by pancreaticoduodenectomy (p-value = 0.03). We believe that pancreatic masses that are not ductal adenocarcinomas, can be aggressively resected even if large in size, resulting in a better outcome than ductal adenocarcinoma itself.

Long-term results of aggressive surgical treatment of primary and recurrent retroperitoneal liposarcomas.

The aim of this study was to establish the role of surgery in the treatment of retroperitoneal liposarcomas. Data concerning 28 patients submitted to surgery for retroperitoneal liposarcoma in our department over the period from 1972 to 1999 were reviewed retrospectively and analysed. Seventy-four operations were performed; in 54% of the operations it was necessary to resect contiguous organs (kidney 60%, colon 50%, adrenal gland 35%). In 89%, grossly curative resection was achieved at the first operation; 20 patients had at least one local recurrence after first operation (median time interval: 22 months). The mean follow-up was 80 months; median survival time was 51 months and 5-year actuarial survival time 51%. Patients with low-grade liposarcoma showed a statistically significant improvement (P < 0.001) in median survival (153 months) versus those with medium- (37 months) and high-grade sarcomas (8 months). At present surgery is still the treatment of choice in the treatment of primary and recurrent liposarcoma; in the case of low-grade liposarcomas especially, an aggressive surgical approach can result in long-term survival.
