From January 1982 to June 1995, 45 patients underwent operation at our department for T3N0M0 non-small cell lung cancer. Tumors invaded chest wall in 38 patients (parietal pleura in 17, subpleural fat tissue in 10, and rib in 11), diaphragm in 3, mediastinum in 3, and pericardium in 1. Extrapleural dissection was performed in 17 patients and en bloc resection of chest wall and lung was performed in 21. Complete resection was possible in 43 patients (96%). Operative mortality was 2.2%. The actuarial overall 5-year survival rate was 63% for the patients with parietal pleura invasion, 45% for those with subpleural invasion, 45% for those with rib invasion, and 56% for those with diaphragm, mediastinal pleura or pericardial invasion. Recurrence at the resected margin was observed in 5 patients with chest wall invasion (subpleural tissue in 3, rib in 2) and 1 with diaphragmatic invasion. In conclusion, we recommend an en bloc resection of the chest wall with enough surgical margin for peripheral tumors firmly adherent to the parietal pleura. 相似文献

OBJECTIVE: To compare chemotherapy with no chemotherapy as palliative treatment for oesophageal squamous cell carcinoma. DESIGN: Randomised study. SETTING: Multicentre trial in France. SUBJECTS: Of 161 patients with histologically confirmed oesophageal squamous cell carcinoma located more than 5 cm from the mouth of the oesophagus, five were withdrawn because of protocol violation. The remaining 156 patients, 149 men and 7 women, mean (SD) age 58 (9) years range 36 to 77, were randomly allocated to either a control group without chemotherapy (n = 84) or a group treated by chemotherapy (n = 72). Patients were divided into four strata: I = complete resection of the tumour but with lymph node involvement (n = 62); II = incomplete resection of tumour leaving gross tumour behind (n = 58); III = no resection because of local or regional invasion (n = 22) ; and IV = no resection because of distant metastasis (n = 14). Exclusion criteria were histologically confirmed tracheobronchial involvement, oesophagotracheal fistula, Karnosky score < 50, cerebral metastases, or hepatic metastases occupying more than 30% of the liver, peritoneal carcinomatosis, associated or previously treated ear-nose-throat carcinoma, or complete resection of tumour without lymph node involvement. INTERVENTIONS: 5 fluorouracil (5FU) and cisplatin (CDDP) were given in 5-day courses, once every 28 days, for a maximum of eight cycles. 5 FU, 1 g/m2, was infused for 24 hours after a water overload, during five days. Cisplatin was given either in one dose of 100 mg/m2 at the beginning of the cycle or 20 mg/m2/day over three hours for five days. Duration of treatment ranged from 6-8 months. OUTCOME MEASURES: Median and actuarial survival. The subsidiary endpoint was quality of survival judged by complications of treatment, swallowing disorders, and the duration of ability to feed normally. RESULTS: There was no difference in survival, either overall (median = 12 months) or in any of the strata. There were however significantly more patients with neurological (p < 0.003), haematological (p < 0.0001), and renal (p < 0.0002) complications in the treated group compared with the control group. Four patients (6%) died of complications of chemotherapy. The course of swallowing disorders did not differ between the two groups. The duration of autonomous oral feeding was exactly the same in both groups (median = 10.5 months). CONCLUSION: The results suggest that 5FU and CDDP do not help in patients with squamous cell carcinoma of the oesophagus whether or not the tumour has been resected. 相似文献

A total of 277 patients with hepatocellular carcinoma (HCC) underwent hepatic resection over a 20-year period. Twelve of 36 patients with recurrence confined to extrahepatic organs underwent surgical resection. There were no complications but one patient died in hospital from secondary intrahepatic recurrence. The 1-, 2- and 5-year survival rates for these 12 patients after hepatic resection were 92, 52 and 26 per cent respectively and were better than those of 24 patients who did not undergo resection for recurrence. The mean survival following resection for recurrent disease was 19.7 months and the longest survival time was nearly 8 years. Secondary recurrence after resection of metastases developed more commonly in the liver than in extrahepatic organs. Among the eight patients who survived for more than 4 months after the second operation, secondary recurrence developed in the liver and extrahepatic organs in eight and four patients respectively. In selected patients with isolated extrahepatic recurrence of HCC, surgery is effective in controlling extrahepatic disease and offers the only chance of long-term survival. 相似文献

We investigated the prognosis of completely resected 119 non-small cell lung cancer patients according to the invaded organs. There was no significant difference in prognosis between T3N0M0 and T3N1M0 patients (5-year survival rate: 34% vs. 38%). However, the prognosis of T3N2M0 patients (5-year survival rate: 11%) was too poor to be regarded as the same category. Therefore, we investigated only T3N0M0 and T3N1M0 patients to assess the contribution of the invaded organs to prognosis. Of the 5 patients with diaphragm invasion, there was no 3-year survivor, and the prognosis of patients with diaphragm invasion was very poor. The chest wall invasion was divided into three parts: parietal pleural invasion, subpleural tissue invasion and intercostal muscular invasion. The 5-year survival rates of patients with such invasion was 35%, 29% and 27%, respectively. The patients with Pancoast tumor had very poor prognosis. T3 factor was heterogeneous, and the prognosis of the patients with T3 tumor was various according to invaded organs. 相似文献

Ultrasonographic features of seven patients with diaphragmatic rupture due to blunt trauma were analyzed. The ruptures occurred at the left hemidiaphragm in four patients and at the right in three. Direct ultrasonographic findings were as follows: disrupted diaphragm in four patients; nonvisualized diaphragm in three patients; floating diaphragm in two patients; and herniation of the liver or bowel loops through the diaphragmatic defect in three patients. Indirect sonographic findings included pleural effusion or subphrenic fluid collection in five patients and splenic laceration in one. Although the number of patients was limited, ultrasonography was very useful for the diagnosis of diaphragmatic rupture. 相似文献

The subjects of this study were 48 asymptomatic patients who had surgery for small hepatocellar carcinoma (HCC). There were 42 men and six women with mean (s.d.) tumour size of 3.31 (1.46) cm and age 55.0 (7.4) years. Follow-up was for a minimum of 10 years. The main concern of this study was a univariate analysis of factors that might affect long-term survival after surgery, which was 50 per cent at 5 years and 31 per cent at 10 years. A high incidence of recurrent HCC (37 of 48 patients) was observed but reoperation further prolonged life in some cases. The significant prognostic factors detected by multivariate analysis were: histological classification, functional liver reserve and histology of the resection margin. Tumour size, gross appearance of tumour, presence of liver cirrhosis, serum alpha-fetoprotein level, age or sex did not affect the prognosis. 相似文献

OBJECTIVE: Hepatitis C virus (HCV) infection is associated with development of hepatocellular carcinoma (HCC). The aim of this study was to examine clinical characteristics and outcome of patients with HCV with or without HCC undergoing liver transplant. METHODS: We reviewed the charts of all 55 patients transplanted between November 1990 and December 1996 for HCV cirrhosis with HCC and compared them with a control group of HCV patients without HCC. Patients with a history of alcohol abuse or HBsAg positivity were excluded. There were 37 men and 18 women, with a mean age of 57.6 yr (range, 19-70 yr) in the HCC group. RESULTS: There was no significant difference between the HCC and nonHCC groups regarding Child's class or United Network for Organ Sharing (UNOS) status at the time of transplant. Twenty-six (45%) patients were diagnosed or suspected of having HCC before transplant. Twenty-five patients (45.5%) had a single focus of HCC. Fourteen percent (seven of 50) of the patients with HCC had been treated with interferon, whereas 12% (six of 52) of patients in the nonHCC group had received interferon. Duration of interferon therapy ranged from 1 to 9 months. All interferon treatment occurred within 5 yr of transplant. A history of intravenous drug use or transfusion was identified in 37 (67%) of HCC patients. Thirty-two patients (58%) without HCC had a parenteral exposure. There was no significant difference in patient or graft survival rates between the patients with and without HCC. CONCLUSION: Approximately one-half of HCC was not detected before liver transplant. There was no significant difference in the mode of transmission, clinical status at the time of transplant, or outcome between the HCV patients with and without HCC. 相似文献

BACKGROUND/AIMS: Pancreatic cancer has a poor prognosis, which is, in part due, to the unfortunately advanced stage, in which the tumor is diagnosed. Since 1973, we have utilized a unique method of extended radical pancreatectomy, using the translateral retroperitoneal approach (TRA) to facilitate combined portal resection. The advantages of this operation are described herein, for patients with carcinoma of the head of the pancreas. In addition, the problems associated with this operation are discussed. METHODOLOGY: Survival was calculated based on type of resection, degree of invasion of the retroperitoneal tissues, degree of lymph node involvement, and cancer stage. Extensive surgery has been performed for pancreatic carcinoma 216 patients. Of these, 14 patients had carcinoma of the head of the pancreas. There were 58 patients who underwent macroscopically curative resections. RESULTS: Only 39 patients were microscopically curative. Ten of the patients who underwent microscopically curative resections, survived for 5 years (34.0%). There were no statistically significant differences in survival based on tumor size. However, there was a significant difference in survival based on extent of invasion of the anterior capsule of the pancreas, extent of invasion of the retroperitoneal tissue, extent of lymph node involvement, cancer stage, and extent of invasion at the surgical margin of resection. CONCLUSION: The results suggest that extended radical pancreatectomy may be indicated for the treatment of cancer of the head of the pancreas. 相似文献

Approximately 80% of hepatocellular carcinoma (HCC) patients in Japan have associated liver cirrhosis, which increases the difficulty of surgical treatment. Liver dysfunction associated with liver cirrhosis is one of the most important predictive prognostic factors for HCC patients. Percutaneous ethanol injection therapy (PEIT) is useful for patients with small HCC or with poor hepatic functional reserve. Transcatheter arterial chemoembolization (TACE) is also useful both for patients with unresectable HCC and patients with multiple intrahepatic recurrence. Liver resection, however, lead to better outcome than other treatments when liver function is maintained after surgery. To determine operative procedures, it is important to evaluate the exact function of remnant liver, based on the preoperative liver function test and the evaluation of tumor character. For advanced HCC patients with vascular invasion, non-surgical treatments such as PEIT or TACE are not indicated, and surgical intervention can be an effective modality to improve their survival. Improvements of surgical technique and perioperative management have decreased fatal complications at a major liver resection and allowed us to carry out liver resection on patients with advanced HCC. 相似文献

The selective delivery of a high dose of radiation to malignant hepatic tumours by infusion of non-biodegradable yttrium-90 (90Y) microspheres via the hepatic artery while sparing the non-tumorous liver parenchyma depends on the tumour-to-normal uptake ratio (T/N) of the therapeutic radiopharmaceutical. Using intrahepatic arterial technetium-99m macroaggregated albumin (99Tcm-MAA), the effect of tumour type, tumour vascularity assessed by hepatic angiography (HAG), tumour size and the degree of extrahepatic shunting on the T/N was investigated in 377 patients with hepatocellular carcinoma (HCC) and 25 patients with colorectal liver metastases. HCC was shown to have a wider range of T/N (0.2-26.5) compared with liver metastases (2.3-7.2). HCC with vascularity grade 1 on HAG had significantly lower T/N but there was no significant difference in HCC with higher vascularity grades. This confirmed that vascularity on HAG does not predict T/N. Overall there was no correlation between T/N and tumour size. Large tumours (> 20 cm) had a significantly lower T/N, probably due to necrosis in the tumour centres. A decrease in mean T/N with increasing percentages of lung shunting was observed in HCC. Determination of T/N by simulation with 99Tcm-MAA is recommended before internal radiation therapy with 90Y microspheres. 相似文献

Repair of fetal diaphragmatic hernia has proven technically difficult especially when the left lobe of the fetal liver is incarcerated in the chest. A step-wise approach from both above and below the diaphragm solves several frustrating technical problems. 相似文献

BACKGROUND: Microwave coagulation therapy (MCT) for hepatocellular carcinoma, which induces tumor coagulonecrosis, is now recognized as an efficient treatment. However, when a tumor is located just below the top of the diaphragmatic dome, laparotomical MCT requires a large incision, and percutaneous MCT is sometimes impossible. PATIENTS AND METHODS: The patients were four men and two women. There were four cases of hepatocellular carcinoma and two cases of liver metastasis from colorectal cancer. All tumors were located below the top of the diaphragmatic dome. Thoracoscopic transdiaphragmatic MCT (TTMCT) was performed under general anesthesia using an endotracheal double-lumen tube. Identification of the tumor site in the liver was performed using an ultrasonic probe under thoracoscopic observation. After the diaphragm above the tumor was opened, a needle electrode to transmit microwaves was inserted directly into the tumor. Microwave irradiation was repeated to coagulate the entire lesion. After completion of TTMCT, the diaphragm was closed thoracoscopically. RESULTS: TTMCT was successfully administered to cancerous lesions in all six patients. The postoperative course was uneventful, and the average postoperative hospitalization period was 10.5 days. None of the patients has shown any recurrence during a follow-up period of 4-23 months. CONCLUSIONS: TTMCT was performed without any difficulty using the thoracoscopic surgical technique, and its therapeutic outcome was satisfactory. This is effective for tumors located just below the top of the diaphragmatic dome. 相似文献

Investigation of the value of the sucking effect of the diaphragm in 44 patients was carried out. The first group consisted of 28 patients who have not undergone hepatic resection. The second group included patients after hepatic resections of various volume in local pathology. The balloon method in modification of this clinic was used for measurement of the value of the sucking effect. In patients of the first group the value of sucking effect was almost two times more under the right cupula of the diaphragm (130.33 + 4.78 mm of water column) in comparison with the left infradiaphragmatic space. It is responsible for presence of the slot between the right half of the liver and the diaphragm, which aggravates the sucking effect. In the second group of patients the value of the sucking effect under the right diaphragmatic cupula was practically the same as in patients of the first group. After right-sided hemihepatectomy the value of the sucking effect under right cupula of the diaphragm has significantly diminished. After resection of the right lobe of the liver as well as after left-sided hemihepatectomy, or without them, the value of sucking effect under left cupula of the diaphragm did not significantly differ. The investigations showed that vacuum-aspiration with vacuum of not less than 150 mm water column should be used for effective drainage of infradiaphragmatic space. 相似文献

A 56-year-old woman was admitted to our hospital with the chief complaint of left back pain. We detected left pleural effusion on chest X-ray and performed chest drainage. No malignant cells were detected in the effusion. Chest CT demonstrated a tumor shadow over the left diaphragm and left pleural effusion 6 months later. She underwent en bloc resection of the tumor and left diaphragm. Histological evaluation revealed malignant fibrous histiocytoma (MFH). Recurrent tumors were found in the abdomen 8 months after the operation, and she underwent resection of the abdominal recurrent tumors. Histological evaluation of the recurrent tumors also showed MFH. The patient died 28 months after the first operation. 相似文献

BACKGROUND: Phrenic nerve palsy in infants and young children usually results from birth injury or iatrogenic damage. The newborn almost invariably presents with severe respiratory distress, diaphragmatic elevation, and paradoxical movement at the affected side. METHODS/RESULTS: In this retrospective analysis a group of 23 patients below the age of 1 year with an obstetric or postoperative phrenic nerve injury was studied and compared with cases in the literature. All patients were admitted between 1986 and 1997 to the Pediatric Surgical Center, Amsterdam. Thirteen of 18 patients with an obstetric phrenic nerve injury underwent plication of the diaphragm after an average observation period of 100 days. In the remaining five children with an obstetric phrenic nerve injury, spontaneous recovery appeared within 1 month. Only one of five patients with a phrenic nerve palsy after a cardiac surgical procedure underwent plication of the diaphragm. Fifteen of the 34 patients described in the literature underwent plication of the diaphragm after an average of 54 days. CONCLUSIONS: If after 1 month no spontaneous recovery of the diaphragmatic paralysis caused by a phrenic nerve injury occurs, plication of the diaphragm is indicated. This operation proved to be successful for relief of symptomatic phrenic nerve injury in all cases. If the condition of the patient clinically deteriorates during this first month of life, the patient should be operated on immediately. 相似文献

The influence of associated viral hepatitis status on 119 patients with primary hepatocellular carcinoma (HCC) undergoing hepatic resection was investigated. Operative morbidity and mortality were examined in three patient groups: 31 patients (group B) positive for hepatitis B surface antigen (HBsAg), 14 (group Be) positive for both HBsAg and hepatitis B e antigen, and 74 (group C) positive for hepatitis C virus antibody (HCVAb). Preoperative liver function in groups Be and C was similar and more impaired than that of patients in group B; combined active hepatitis was seen most frequently in group C (68 per cent). The tumour size in group B was significantly greater than that in groups Be and C. Postoperative complications occurred more frequently in group C (39 per cent) and early postoperative deaths, other than those from cancer, were seen in nine patients positive for HCVAb, of whom three developed postoperative liver failure. Patients with HCC and hepatitis B without seroconversion as well as hepatitis C frequently have active hepatitis, which may impair liver function and play an important role in operative morbidity and mortality. 相似文献

The aim of the study is to discuss our observations concerning oesophagogastric bypass anastomosis in cases with scar stricture of cardia in long-term achalasia (megaoesophagus). The Heller operation is ineffective in such patients and the resection of cardia with oesophagogastric anastomosis is a large and controversial operation. 16 patients were operated (6 of them after ineffective cardiomyotomy). In all cases long-term dysphagia, big loss of weight and large, S-shaped oesophagus lying on the diaphragm were found. The left side thoracotomy was performed and fundus of the stomach was dislocated to the chest through dilatatored oesophageal hiatus and with the oesophagus above the cardia. There were no postoperative complications. However, dysphagia regressed. The remote results (from 1 year to 7 years) in 11 patients were analysed. The general condition was satisfactory. No dysphagia and gastrooesophageal reflux was revealed. Anastomosis was efficient in X-ray examination. Our observations indicate that oesophagogastric anastomosis is a procedure of choice in the treatment of long-term achalasia with stricture of cardia and megaoesophagus. 相似文献

BACKGROUND: The development of endocrine tumours of the duodenopancreatic area (ETDP) is thought to be slow, but their natural history is not well known. The aim of this study was to determine the factors that influence survival of patients with ETDP. PATIENTS/METHODS: Eighty two patients with ETDP (44 non-functioning tumours, 23 gastrinomas, seven calcitonin-secreting tumours, four glucagonomas, three insulinomas, one somatostatinoma) followed from October 1991 to June 1997 were included in the study. The following factors were investigated: primary tumour size, hormonal clinical syndrome, liver metastases, lymph node metastases, extranodular/extrahepatic metastases, progression of liver metastases, local invasion, complete resection of the primary tumour, and degree of tumoral differentiation. The prognostic significance of these factors was investigated by uni- and multi-variate analysis. RESULTS: Twenty eight patients (34%) died within a median of 17 months (range 1-110) from diagnosis. Liver metastases (p = 0.001), lymph node metastases (p = 0.001), progression of liver metastases (p < 0.00001), lack of complete resection of the primary tumour (p = 0.001), extranodular/extrahepatic metastases (p = 0.001), local invasion (p = 0.001), primary tumour size > or = 3 cm (p = 0.001), non-functioning tumours (p = 0.02), and poor tumoral differentiation (p = 0.006) were associated with an unfavourable outcome by univariate analysis. Multivariate analysis identified only liver metastases (risk ratio (RR) = 8.3; p < 0.0001), poor tumoral cell differentiation (RR = 8.1; p = 0.0001), and lack of complete resection of the primary tumour (RR = 4.8; p = 0.0007) as independent risk factors. Five year survival rates were 40 and 100% in patients with and without liver metastases, 85 and 42% in patients with and without complete resection of primary tumour, and 17 and 71% in patients with poor and good tumour cell differentiation respectively. CONCLUSION: Liver metastases are a major prognostic factor in patients with ETDP. Progression of liver metastases is also an important factor which must be taken into account when deciding on the therapeutic approach. The only other independent prognostic factors are tumoral cell differentiation and complete resection of the primary tumour. 相似文献

Excess parenchymal loss associated with hepatectomy is the leading risk factor/for liver failure especially in patients with impaired hepatic function. Selective portal embolization (PE) before hepatectomy is aimed to induce an atrophy of the embolized lobe to be resected, with a compensatory hypertrophy of the/counterlobe to be preserved. We performed PE followed by hepatectomy in 58 patients with hepatocellular carcinoma (HCC, n. = 44) or metastatic liver tumour (MLT, n. = 14). All the patients well tolerated PE, and hepatic functional data returned to the baseline levels within a week. The left lobe volume increased by about 10% after the right PE. Hepatectomy procedures undertaken comprised right or extended right lobectomy (n. = 39), central bisegmentectomy (n. = 3), extended segmentectomy (n. = 12), and limited resection (n. = 4). The 25 of HCC patients underwent right-sided lobectomy despite a presence of hepatic functional impairment, and the 3 of MLT patients under went right lobectomy with additional resection of the left lobe. As a whole, the operative morbidity and mortality rates were 15.5% and 1.7%, respectively (one patient died of liver failure). The 5-year over all survival rates were 46.8% in HCC patients and 38.0% in MLT patients, respectively. Preoperative PE therefore can be an ancillary procedure for patients, despite with hepatic dysfunction or with bilobar tumours, who may need extensive hepatectomy. 相似文献
