Subcutaneous metastasis of pancreatic cancer in the site of percutaneous biliary drainage.

A subcutaneous metastatic lesion from a carcinoma of the pancreas or common bile-duct along the tract of a percutaneous transhepatic biliary drainage is a rare finding. Prompted by a case that came to our observation by chance, we reviewed the literature and analysed the 29 cases collected. Neoplastic cell seeding along a percutaneous drainage tract, albeit rare, must be kept in mind. The complication can be avoided if patients at risk, whenever possible, undergo endoscopic drainage.

Giant diverticulum of the sigmoid colon with perforation. Report of a case.

We present a case of perforated giant diverticulum of the sigmoid colon. This condition is extremely rare and only a few cases have so far been reported in the literature. Our case involved a 55-year old woman. Diagnosis was easy with barium enema and CT scan examination. Laparotomy revealed a giant diverticulum of the sigmoid colon compressing adjacent structures with signs of inflammation. An en bloc resection of the sigmoid colon, ovary and fallopian tube was performed with primary colon-rectal anastomosis. The post-operative course was uneventful.

Bronchioloalveolar carcinoma: clinical, radiographic, and pathological findings. Surgical results.

BACKGROUND: Bronchioloalveolar carcinoma (BAC) remains one of the most controversial of lung cancer subtypes. METHODS: From 1980 to 1998, 374 resected patients for NSCLC were followed up in our department. Of the 147 cases histologically defined as adenocarcinoma, 34 were pure BAC. The records of these 34 patients were retrospectively reviewed in order to evaluate patient and tumor characteristics and to identify which variables had a prognostic impact on survival and recurrence rate. RESULTS: Patient age, sex, smoking habits and symptoms were not differentiating characteristics when related to radiographic presentation or to natural history. Mucinous cell-type (23.6% of cases) was more frequent with non-smokers, presence of a single nodule or mass and stage I. Favorable characteristics were: a) the prevalence of stage I and N0 cases (59% and 76.7% of cases, respectively) with a mean survival time of 66 and 77 months, respectively; and b) the radiographic presentation of a solitary pulmonary nodule or mass (76.4% of cases), that, independently of nodal involvement, showed a higher mean survival time (62 months). Independently significant adverse prognostic factors were: stage II-IV, lymph node involvement, and patient age over sixty years. The radiographic presence of multiple or satellite nodules was related to a significantly adverse prognosis (mean survival time: 18 months) by univariate analysis; this was not confirmed by multivariate analysis. CONCLUSIONS: In our experience BAC was the NSCLC subtype more frequently associated with a good outcome after resection; surgery should not to be denied also in patients with multiple nodules, when under sixty years of age and no lymph node involvement.

[Lipoma of the small intestine: a rare cause of intestinal invagination].

Lipomas are an uncommon cause of small-bowel obstruction. The symptoms are intermittent and nonspecific. The Authors report a case in which intussusception was diagnosed with echography and the obstruction was treated with resection. They conclude that lipomas must always be considered in the differential diagnosis of intrabdominal neoplasms and in intestinal obstructions.

Surgical approach to non-small cell lung cancer involving the chest wall.

Treatment of NSCLC invading the chest wall (T3) remains controversial. Surgery is undoubtedly the only chance for these neoplasms, but its role regarding the T3N2 tumors is highly questionable. Between 1975 and 1994, 710 NSCLC patients underwent surgery in our department. Of these, 38 with tumor involvement of the chest wall underwent curative resection: en bloc resection or extrapleural resection, and 31 of these patients (19 with T3N0 tumors and 12 with T3N1-N2 tumors) were available for estimating long-term survival. The overall survival was 20.5% at 5 years and 15.4% at 10 years. Patients without lymph-node involvement had a survival rate of 26.2% at 5 years and 19.27% at 10 years. No patient with T3N2 tumor was alive 5 years after surgery. Patients with T3N1 tumor had a survival rate of 16.7% at both 5 and 10 years. The difference between T3N0 and T3N2 tumors was statistically significant. Neither histologic type nor depth of chest wall involvement had a significant impact on survival. En bloc or extrapleural resection, if curative, can be effective in T3N0-N1 tumors. Surgery is inadequate for the treatment of T3N2 tumors with chest wall involvement.

Diagnosis controversies for adrenal ganglioneuroma.

The authors report a case of adrenal ganglioneuroma which was incidentally diagnosed performing preoperative examination for a sigmoid carcinoma. The authors took this finding as a starting point to underline the rarity of this condition and its chance discovery, this being due to the rare presence of signs and symptoms and its frequent association with other synchronous neoplasms; all this makes differential diagnosis rather difficult.

Technetium-99m tetrofosmin single photon emission computed tomography in the evaluation of suspected lung cancer.

Technetium-99m-tetrofosmin is a radiopharmaceutical employed for myocardial imaging, which has recently emerged as useful in the visualization of tumors. In this study technetium-99m-tetrofosmin was evaluated for its accuracy in differentiating malignant from benign pulmonary lesions, and in detecting mediastinal node metastasis due to lung cancer. Eighty-one patients with a solitary lung lesion on the chest radiograph and/or CT scan were submitted to chest single photon emission computed tomography after technetium-99m-tetrofosmin injection (740 MBq i.v.). The scintigraphic findings were correlated to the final histopathological diagnosis, demonstrating abnormal tracer accumulation in 51 of 54 malignant lesions (sensitivity 94%) and in 4 out of 27 benign conditions (specificity 85%), yielding an accuracy of 91%. Mediastinal lymph-node involvement was evaluated in 35 patients with non small cell lung cancer who underwent mediastinoscopy and/or surgery. Tetrofosmin accuracy (89%) was significantly higher than that of CT (69%, p < 0.05); the false negative scintigraphic results were in nodes sized less than 1 cm. In conclusion, technetium-99m-tetrofosmin imaging is useful in distinguishing malignant from benign pulmonary lesions, and in non-invasively assessing mediastinal node metastases from non small cell lung cancer, especially in patients with enlarged nodes by CT scan.

[The usefulness and limits of echo-endoscopy in the clinical staging of esophageal cancer].

Endoscopic ultrasonography (EUS) is a diagnostic method of considerable value for the local staging of esophageal cancer, in particular for T and N evaluation. After an extensive review of the literature, the authors underline the possibility of using EUS to improve the treatment and prognosis of esophageal neoplasms based on the use of various stage-dependent therapeutic strategies. EUS is regarded as a gold-standard technique for esophageal cancer staging in order to select appropriate treatment options, but is currently hampered by the intrinsic difficulty and subjectivity of interpreting ultrasonographic images. In order to ensure safe and reliable data, EUS must be carried out by operators who have undergone suitable training at a specialised centre.

Small bowel schwannoma with diffuse subcutaneous lipomatosis. Case report and literature review.

A case of a small-bowel schwannoma with diffuse familiar lipomatosis is described. This case underlines the rarity of the neoplasm and its probably chance association with subcutaneous lipomatosis. The intestinal neoplasm was diagnosed preoperatively by upper gastrointestinal endoscopy and a small-bowel enema; computed tomography scan confirmed the intestinal lesion. Attention is focused on the morphological features of intestinal schwannomas and their biological behaviour.

Pericardial cysts of the mediastinum.

Pericardial cysts are an uncommon benign disease. Their treatment, in the past, was based on excision by thoracotomy or, in selected cases, on percutaneous aspiration. The progress of video-assisted thoracoscopy gave new possibilities, but most surgeons still consider the thoracotomic approach as the treatment of choice. The aim of this study is to report our experience and to discuss the role of different therapeutic procedures in the management of pericardial cysts. Between 1970 and 1996, 24 patients with pericardial cysts were treated at the first Department of Surgery of the University of Rome < >. Of 24 cysts, six were located in the right cardiophrenic angle, three in the left cardiophrenic angle, two in the subcarenal areas, one in the paracardiac area and one on the posterior mediastinum. Ten patients were asymptomatic. Diagnosis was performed preoperatively only in patients with cysts typically located in the cardiophrenic angle. Twenty-three patients were surgically treated by a standard posterolateral thoracotomy or limited thoracotomy with sparing of muscles. One patient underwent CT-guided transparietal fine-needle aspiration. There were no cases of operative mortality. Morbidity was 12.5% and consisted of retained secretions, moderate hypoxemia and partial atelectasis. All patients were submitted to a long-term follow-up and no cyst recurrences were found. We conclude that excision via thoracotomy is an optimal treatment for pericardial cysts. Limited thoracotomy with sparing muscles offers a good cosmetic result and a rapid functional respiratory recovery. Percutaneous cyst aspiration may be, in selected patients, an attractive alternative to surgery.

Hemodynamic and pulmonary changes during and after laparoscopic cholecystectomy. A comparison with traditional surgery.

BACKGROUND: The cardiopulmonary changes experienced by patients who undergo laparoscopic cholecystectomy (LC) and the prognostic value of patient characteristics are not well understood. METHODS: Cardiorespiratory changes were investigated in 120 patients undergoing LC or open cholecystectomy (OC). The results and their relation to patient variables were statistically evaluated. RESULTS: The most significant cardiorespiratory changes were (A-a)PO2 increase during OC; decrease of pH and compliance and increase of peak airway pressure during LC; impairment of arterial blood gas mean values and respiratory muscle strength; atelectasis and pneumonia (five cases) after OC; and lamellar atelectasis (two cases) after LC. Significant adverse prognostic factors related to intra- and postoperative LC cardiorespiratory changes were ASA class greater than I, FEF75-85% < 900 ml, and PaO2 < 10.4 kPa (PPV, 71.4% and 46.6%, respectively). CONCLUSIONS: LC carries no significant cardiorespiratory changes provided that intraoperative monitoring of hemodynamics and respiratory parameters is done for the study of blood gas values in all patients at risk.

[Adenomatous tissue in colorectal carcinomas: clinical significance and probable histogenetic implications of morphological differences].

In this study we tested the hypothesis that colorectal cancers containing adenoma (CCA) could be a different entity from colon cancers without adenoma (CSA). Clinical data, histologic preparations of operative specimens and survival of 210 patients who underwent resective surgery for colorectal cancer were studied. Adenomatous tissue within the cancer was found in 62 of 210 carcinomas (CCA), the other 148 cancers were lacking adenomatous features (CSA). CCA occurred more frequently in female patients (p = 0.003). Synchronous adenomas were detected in the resected colon of 19 out 62 CCA and of 24 out 148 CSA (p = 0.04). CCA showed the extent of intraparietal spread (p = 0.001), grade (p = 0.007) and stage (p = 0.004) lower than CSA. These characteristics also appeared statistically related to size of the cancers. The adenomatous tissue within CCA was tubular in 4 cases, tubulo-villous in 34 and villous in 24 cases. The villous histotype was statistically related to the older age of patients (p < 0.0001), larger cancer size (p = 0.01), presence of synchronous adenomas in the resected colon (p = 0.02) and higher histologic grade of the cancer (p < 0.05). Patients with CCA evidenced a higher 5-year survival rate (p = 0.02). Our results evidence epidemiologic, clinical and pathologic differences between CCA and CSA and suggest a possible double histogenesis of colon cancer.

Carcinoma of the duodenum: management and survival in 14 cases.

AIMS: The aim of this study is to evaluate the role of surgery in the treatment of adenocarcinoma of the duodenum. METHODS: From 1955 to 1994, 14 patients with primary adenocarcinoma of the duodenum underwent surgical treatment in our department. Presenting signs and symptoms were mainly related to obstruction and bleeding. Upper gastrointestinal contrast study, Computed Tomography (CT) and duodenoscopy were the primary diagnostic procedure modalities. All diagnoses were confirmed histologically. The tumors were staged pathologically according to the new TNM classification (UICC, 1992). Eight patients received palliative treatment or exploratory laparotomy. The remaining 6 patients were resectable for cure. RESULT: Operative mortality was 35.7%. The 5-year survival rate for patients who underwent curative resection was 33.3%. None of the patients who underwent palliative procedures or exploratory laparotomy survived for more than 11 months. CONCLUSIONS: In the management of resectable adenocarcinomas of the duodenum surgical radicality including lymphadenectomy should be pursued. Unresectable adenocarcinomas treated with palliative procedure had a very poor prognosis.

Rhodococcus equi pneumonia in a patient with occult HIV infection: successful therapy.

We report a case of Rhodococcus equi cavitary pneumonia in a 37-year-old patient with occult HIV infection. Because of his good immune status, the patient was given oral erythromycin and rifampin which rapidly resolved the infection. This modality of treatment may be sufficient in HIV-positive selected patients fur the resolution of Rhodococcus equi pneumonia.

[Evaluation of the respiratory function by lung scintigraphy in patients candidates for pulmonary resection].

Sixty-one patients undergoing pulmonary resection were studied pre- and post-operatively by spirometry, arterial gas determination, and quantitative ventilation/perfusion lung scanning. Our results showed that ventilation and/or perfusional scintigraphic scanning is currently the most reliable method in identifying patients at risk for postoperative respiratory insufficiency. Specifically, this technique was successful in detecting pulmonary areas other than those to be resected presenting ventilation or perfusional abnormalities. Therefore, the technique is particularly useful in predicting residual pulmonary function.

[The experience of an outpatient service of breast pathology. I. The diagnostic procedure for screening].

The authors underline the importance of correct screening in the female population in order to achieve as early a diagnosis as possibly of malignant breast tumours. In view of the high frequency of this neoplasia, as well as the encouraging results of numerous tested diagnostic protocols in terms of their positive influence on the progress of this disease, the authors prepared a screening protocol within a breast pathology service, and report the results achieved during the course of about seven years. Out of a total of 5000 patients aged between 30 and 90 years old, a total of 261 cases were diagnosed with pathologies requiring surgery with a 57.9% incidence of carcinoma, among which, in compliance with reports in the literature, a net predominance was found of initial stage tumours with diameter of less than 2 cm (58.3%).
