Influence of age on operative mortality and long-term survival after lung resection for bronchogenic carcinoma.

The proportion of elderly patients presenting with bronchogenic carcinoma is increasing. To study the impact of age on clinical presentation, management and outcome of patients, the authors have reviewed their clinical experience over the last 20 yrs. Between 1977 and 1996, 1,079 patients underwent thoracotomy for primary lung carcinoma in the authors' institution. Patients were grouped by age at the time of surgery as <60 yrs, 60-69 yrs and > or =70 yrs. Although the mode of clinical presentation was similar between all age groups, patients <60 yrs were more prone to have advanced stage carcinoma at the time of diagnosis. The rates of exploratory thoracotomy and pneumonectomy were higher in patients <70 yrs, whereas lobectomies and lesser resections largely predominated in patients > or =70 yrs. The mortality rate following lobectomy and lesser resection increased from 1.3% in patients <60 yrs to 5.5% in patients > or =60 yrs (p=0.04) and the mortality rate following pneumonectomy increased from 6.5% in patients <60 yrs to 13.7% in patients > or =70 yrs (p=0.24). The specific long-term survival, which included only the patients who died from primary lung carcinoma, was similar in all age groups. Operative mortality and survival rates are acceptable in patients > or =70 yrs. Therefore, age in itself should not constitute a contraindication to surgical lung resection for primary lung carcinoma as long as a careful preoperative assessment is performed to appropriately select surgical candidates.

Management of bleeding pseudoaneurysms in patients with pancreatitis.

BACKGROUND: Bleeding pseudoaneurysm is a rare but frequently fatal complication in patients with pancreatitis. METHOD: The medical records of ten patients who presented to this institution with a bleeding pseudoaneurysm between 1978 and 1997 were reviewed retrospectively. Six patients had chronic pancreatitis and four had acute pancreatitis. The splenic artery was involved in six cases, a pancreaticoduodenal artery in two, the gastroduodenal artery in one and the cystic artery in one. RESULTS: Computed tomography (CT) revealed the bleeding pseudoaneurysm in all patients (n = 6) with chronic pancreatitis but in only one of three with acute pancreatitis. Arteriography always gave the correct diagnosis. Seven patients underwent pancreatic resection as an emergency (n = 3) or within 48 h (n = 4), and survived. Three patients presenting with acute pancreatitis and massive bleeding underwent transcatheter arterial embolization. Two of them had a favourable outcome and one died from a recurrent haemorrhage 7 days later. Overall, two patients suffered significant perioperative complications and one died. CONCLUSION: CT is accurate in the diagnosis of pseudoaneurysms complicating pseudocysts. Primary resection of the pseudoaneurysm, which frequently requires pancreatic resection, is the treatment of choice. Angiography followed by transcatheter embolization is effective, but should be rapidly followed by operation.

Incidence, risk factors and management of bronchopleural fistulae after pneumonectomy.

Postpneumonectomy bronchopleural fistula (BPF) remains a serious and often life-threatening complication. Over a seven-year period, seven cases of BPF occurred in a series of 100 consecutive pneumonectomies performed for lung carcinoma by the same surgical team. The incidence increased from 3% (1/33) prior to 1993 to 9% (6/67) thereafter. The presence of tumour within the main stem bronchus and the need for postoperative mechanical ventilation correlated significantly with the occurrence of BPF. However, it is likely that other risk factors, such as the introduction of systematic mediastinal lymph nodes dissection since 1992 and bronchial stapling since 1993, were involved. In four patients, closure of BPF was achieved by transposition of pedicled latissimus dorsi (LD) muscle flap and closed-chest irrigaiton of the pleural cavity. Patients were discharged after a median stay of 19 d; fistula recurred in one case and was successfully treated with an omental flap. No complications related to the LD division were observed. In conclusion, mediastinal lymph node dissection may increase the risk of post-pneumonectomy BPF. Systematic bronchial stapling should be used cautiously, especially if the tumour is present within the main stem bronchus. Treatment with predicted LD muscle flap or omental flap associated with closed-chest irrigation proved to be simple, time-saving and efficient.

Primary pulmonary meningioma presenting as lung metastasis.

A benign primary pulmonary meningioma, an extremely rare tumour, was incidentally detected in a 57-year-old woman in association with a contralateral pulmonary adenocarcinoma. The meningioma was initially suspected to be a metastasis. Both tumours were excised, with excellent outcome. Anatomic features of primary pulmonary meningioma and differential diagnosis are discussed.

Management of true aneurysms of the pancreaticoduodenal arteries.

OBJECTIVE: To review the authors' recent experience and that of the literature since 1973 and to provide management guidelines for true aneurysms of the pancreaticoduodenal arteries (PDA). SUMMARY BACKGROUND DATA: True aneurysms of the PDA are rare, with a total of only 52 cases reported since 1973. METHODS: Six patients were admitted to the authors' institution between 1985 and 1995 for rupture of a true aneurysm of the PDA. They were analyzed with regard to the mode of presentation, preoperative workup, management, and outcome. RESULTS: All patients had severe epigastric pain from retroperitoneal hemorrhage. Computed tomography scanning and angiography were performed in all cases. Aneurysms ranged from 0.7 to 1.2 cm (median 0.9 cm). The celiac axis was stenotic or occluded in five cases. Three patients underwent emergency pancreatoduodenectomy. Two of them survived. In one case, section of the median arcuate ligament was associated with the procedure, and the patient died from an aortic dissection. Embolization was performed in the last three patients. The procedure was definitive in two cases. In one, hemorrhage recurred 8 days later and required surgical ligation of the bleeding artery. CONCLUSIONS: The authors recommend rapid treatment of all true aneurysms of the PDA. Because most of these aneurysms result from a stenosis of the celiac axis, selective embolization may help to preserve patency of the PDA and should, therefore, be the primary therapeutic choice in ruptured aneurysms. Close follow-up is mandatory because of possible recurrent bleeding. Appropriate and expeditious management of true PDA aneurysms should help reduce the mortality rate.

[Primary pulmonary carcinoma and Pancoast syndrome].

INTRODUCTION: Although the treatment of Pancoast tumours usually combines radiotherapy and surgery, poor prognosis has been reported. The influence of clinical signs and extension of surgical resection on long-term survival has not yet been systematically investigated. METHODS: Between 1977 and 1997, among 1129 patients operated consecutively in our institution for a bronchogenic carcinoma, 14 (1.2%) presented a Pancoast tumour. Delay between the onset of symptoms and definite diagnosis ranged from 1 to 14 months (median 7 months). A complete surgical resection was performed in 7 patients, 6 of whom did not have mediastinal lymph node metastasis. Radiotherapy or radiochemotherapy was performed in all patients. RESULTS: Overall 5-year survival rate is 36%. However, 5-year survival rate increases up to 60% if the diagnosis is established within 6 months after the onset of symptoms, and up to 67% if the tumour has been removed without mediastinal lymph node metastasis. In contrast, the 5-year survival rate decreases to 20% or 0% respectively, if symptoms last more than 6 months, or if tumoral resection is incomplete. CONCLUSIONS: The incidence of Pancoast tumours compared to other bronchogenic carcinomas is low. An early diagnosis allows complete resection of the tumour and contributes to improve survival.

[Hemosuccus pancreaticus: a rare cause of upper gastrointestinal hemorrhage].

We report on a patient with alcoholic chronic pancreatitis and intermittent upper gastrointestinal haemorrhage. Old blood was seen in the duodenum but no bleeding source could be identified by endoscopy. Computed tomography scanner and angiography disclosed an arterial pseudoaneurysm of the pancreatic tail, and left splenopancreatectomy was performed. In cases of upper gastrointestinal haemorrhage, the pancreas should be considered as a bleeding source if endoscopies remain negative and the patient presents with chronic pancreatitis.

[Surgical treatment of severe emphysema: lung transplantation or volume reduction?].

In recent years, lung transplantation (LT) and volume reduction surgery (LVRS) have been proposed for selected patients with end-stage pulmonary emphysema. Retrospectively, we analyzed the perioperative time course of 30 patients with emphysema who underwent either LVRS (n = 17) or LT (n = 13). In the LVRS group, patients were significantly older, presented less severe functional disability and all but one could be extubated at the end of surgery. In contrast, patients undergoing LT required postoperative mechanical ventilation (19 +/- 11 hrs) and had a prolonged hospital stay (37 [25-60] days vs 19 [11-42] days in LVRS patients) due to reperfusion lung edema, infection, hemorrhage and acute rejection. Six months postoperatively, forced expiratory volume in 1 second was improved and was significantly larger after LT compared with LVRS (+200% vs +63%). Our preliminary results suggest that, although LT produces greater functional improvement, LVRS is associated with lower surgical risk and is an alternative therapy in selected patients with severe emphysema.

Management of true aneurysms of the splenic artery.

BACKGROUND: Splenic artery aneurysms (SAA) are detected with increasing frequency but their management still remains controversial. This paper relates our experience in the outcome and management of ruptured aneurysms of the splenic artery. METHODS: Between 1977 and 1996, 8 patients presented to our institution with a ruptured SAA. Their ages ranged from 25 to 72 years (mean 55 ys). RESULTS: All patients presented with rupture as the first sign of SAA. One patient was at 32 weeks of gestation and rupture suggested placental abruption. Three patients required cardiopulmonary reanimation prior to surgical procedures. Splenopancreatectomy (n = 4), splenectomy (n = 2), and ligation of the splenic artery (n = 1) were performed. Seven of the 8 patients survived. Size of aneurysms ranged from 2 cm to 3.5 cm (mean 3 cm). CONCLUSIONS: SAA may rupture at any age. Diagnosis during pregnancy rests upon a high index of suspicion. The mortality rate remains low if immediate resuscitation is performed and an aggressive surgical approach is taken.

Muscle-sparing anterior thoracotomy for one-stage bilateral lung volume reduction operation.

Bilateral lung volume reduction produces significant clinical and physiologic improvement in selected patients with end-stage emphysema. Current surgical approaches consist of median sternotomy and video-assisted thoracoscopy. This report describes an alternate technique of single-stage, bilateral lung volume reduction using muscle-sparing anterior thoracotomy in 18 patients with severe lung emphysema.

Massive contralateral pneumonia following thoracotomy for lung resection.

Separation of the lungs with a double-lumen endobronchial tube facilitates the surgical approach and protects the bronchial system from contamination by pus or blood from the operated lung. We report a case of a 49-year-old man who suffered a gram-negative pneumonia requiring mechanical ventilatory support and prolonged hospitalization after pulmonary resection. Contamination of the ventilated-dependent lung was documented intraoperatively. Current information on postoperative infectious complications and preventive measures are discussed.

Abdominal lymphangioma in adults and children.

BACKGROUND: Abdominal lymphangioma is a rare tumour usually classified with mesenteric and retroperitoneal cysts. This experience of abdominal lymphangiomas contrasts the differences between tumours in children and adults. METHODS: Between 1970 and 1996, six patients had surgical resection of an abdominal lymphangioma. RESULTS: There were three children aged 4 years or less and three adults aged 36-76 years. Two children presented with an acute abdomen and one with a rapidly enlarging abdominal girth. Lymphangiomas were located in the mesentery and gastrointestinal tract. In adults, symptoms lasted from months to years and lymphangiomas were found in the pancreas, spleen and retroperitoneum. CONCLUSION: In this series, abdominal lymphangioma presented more acutely in children and usually involved the mesentery, whereas in adults the history was longer and the tumour was found in the retroperitoneum.

Successful combined lung and kidney transplantation for pulmonary lymphangioleiomyomatosis and renal angiolipomas.

Pulmonary lymphangioleiomyomatosis (LAM) and renal angiolipomas are rare but distinct clinical entities that share similar morphological features. Lung transplantation is considered as a valuable therapeutic modality in patients with end-stage pulmonary LAM. However, in some patients, renal complications due to bleeding angiomyolipomas and cyclosporin-induced nephropathy have become newly identified problems. This study reports the first case of combined lung and kidney transplantation for pulmonary lymphangioleiomyomatosis and renal angiolipomas. Two years after transplantation, renal and pulmonary function have remained stable and the patient has resumed a normal daily life, including a full-time professional activity.

Long-term results after surgical management of chronic pancreatitis.

BACKGROUND/AIMS: Long-term outcome in surgery for chronic pancreatitis remains relatively unknown. METHODOLOGY: Between 1963 and 1993, we performed 123 pancreatic resections and 35 drainage procedures for severe chronic pancreatitis. We reviewed 131 patients with a mean follow-up of 48 months (4 months to 18 years). RESULTS: Actual 10-year survival was 82% for nonalcoholic patients and 51% for alcoholic pancreatitis. Pain was successfully treated in 71% with pancreatic resection and in 42% with drainage procedures (p<0.01). Although post-operative diabetes mellitus occurred in 56% of patients after pancreatic resection, long-term nutritional status was similar after pancreatic resection and drainage procedures. Weight gain could be observed in 75 patients (47%) and quality-of-life was good to excellent in 97 patients (74%). CONCLUSIONS: In conclusion, long-term survival was mainly conditioned by the etiology of the disease. Pancreatic resections were more successful in treating intractable pain than drainage and required fewer re-interventions. As presumed, resections were associated with a higher rate of diabetes mellitus, but this, however, had no impact on long-term nutritional status and quality-of-life.

Do aneurysms and pseudoaneurysms of the splenic artery require different surgical strategy?

BACKGROUND/AIMS: Although aneurysms and pseudoaneurysms of the splenic artery may result in life-threatening hemorrhage, their etiology, mode of presentation, and surgical strategy seem to differ. In an attempt to clarify their management, we reviewed our experience with aneurysms and pseudoaneurysms of the splenic artery. METHODOLOGY: Between 1977 and 1997, 10 patients were operated on for true aneurysm and 6 for pseudoaneurysm of the splenic artery. RESULTS: True aneurysms required resection because of rupture (n=7), size (n=2), and anticipated pregnancy (n=1). They remained asymptomatic unless rupture had occurred. Treatment consisted in aneurysmectomy with preservation of the pancreas and spleen when asymptomatic and required splenectomy or splenopancreatectomy when ruptured. Pseudoaneurysms were always associated with chronic pancreatitis and symptoms had lasted from several hours to 4 weeks prior to hospitalization. Caudal splenopancreatectomy was required in all but one case. CONCLUSIONS: To contrast true aneurysms, pseudoaneurysms most often present with massive or intermittent bleeding. While the spleen and pancreas should be preserved when treating asymptomatic true aneurysms, management of ruptured aneurysms and pseudoaneurysms of the splenic artery usually consists of splenectomy or splenopancreatectomy.
