1/599. Intrathoracic suture abscess after lobectomy for early lung cancer.

    Intrathoracic suture abscess may occur around sutures on the pleura or in the lung parenchyma, although it is rare to encounter such cases clinically. We report on a 68-year-old woman with an intrathoracic (extrapulmonary) suture abscess, which was discovered on a chest x-ray film one year after right-middle lobectomy for early lung cancer. The abscess was removed surgically, and the postoperative course was uneventful. Pathological examination showed that it was caused by braided polyester sutures.

3/599. Transient pseudo-hypoaldosteronism following resection of the ileum: normal level of lymphocytic aldosterone receptors outside the acute phase.

    Pseudo-hypoaldosteronism (PHA) is due to mineralocorticoid resistance and manifests as hyponatremia and hyperkalemia with increased plasma aldosterone levels. It may be familial or secondary to abnormal renal sodium handling. We report the case of a 54-year-old woman with multifocal cancer of the colon, who developed PHA after subtotal colectomy, ileal resection and jejunostomy. She was treated with 6 g of salt daily to prevent dehydration, which she stopped herself because of reduced fecal losses. One month later she was admitted with signs of acute adrenal failure, i.e. fatigue, severe nausea, blood pressure of 80/60 mmHg, extracellular dehydration, hyponatremia (118 mmol/l); hyperkalemia (7.6 mmol/l), increased blood urea nitrogen (BUN) (200 mg/dl) and creatininemia (2.5 mg/dl), and decreased plasma bicarbonates level (HCO3-: 16 mmol/l; N: 27-30). However, the plasma cortisol was high (66 microg/100 ml at 10:00 h; N: 8-15) and the ACTH was normal (13 pg/ml, N: 10-60); there was a marked increase in plasma renin activity (>37 ng/ml/h; N supine <3), active renin (869 pg/ml; N supine: 1.120), aldosterone (>2000 pg/ml; N supine <150) and plasma AVP (20 pmol/l; N: 0.5-2.5). The plasma ANH level was 38 pmol/l (N supine: 5-25). A urinary steroidogram resulted in highly elevated tetrahydrocortisol (THF: 13.3 mg/24h; N: 1.4 /-0.8) with no increase in tetrahydrocortisone (THE: 3.16 mg/24h; N: 2.7 /-2.0) excretion, and with low THE/THF (0.24; N: 1.87 /-0.36) and alpha THF/THF (0.35; N: 0.92 /-0.42) ratios. The number of mineralocorticoid receptors in mononuclear leukocytes was in the lower normal range for age, while the number of glucocorticoid receptors was reduced. Small-bowel resection in ileostomized patients causes excessive fecal sodium losses and results in chronic sodium depletion with contraction of the plasma volume and severe secondary hyperaldosteronism. Nevertheless, this hyperaldosteronism may be associated with hyponatremia and hyperkalemia suggesting PHA related to the major importance of the colon for the absorption of sodium. In conclusion, this case report emphasizes 1) the possibility of a syndrome of acquired PHA with severe hyperkalemia after resection of the ileum and colon responding to oral salt supplementation; 2) the major increase in AVP and the small increase in ANH; 3) the strong increase in urinary THF with low THE/THF and alpha THF/THF ratios; 4) the normal number of lymphocytic mineralocorticoid receptors outside the acute episode.

4/599. Pericardial tamponade: an unusual complication of lobectomy for lung cancer.

    A rare case of pericardial tamponade developed in a 69-year-old man after a right upper lobectomy for lung cancer. This unusual complication presented in the early postoperative period and was associated with what we believed to be an aberrant right bronchial artery coming off the intrapericardial portion of the aorta. This vessel retracted into the pericardial sac where it bled causing a pericardial tamponade.

5/599. Metachronous cancers or late recurrences after resection of stage I lung cancer.

    In 2 patients with stage I lung cancer, tumors recurred at their resection lines 10 years after the original surgical resections. These cases suggest that the prognosis of late cancer occurrences after resected primary lung malignancies might be related to the interval of time between primary and subsequent cancers rather than to their categorization as recurrent or metachronous cancers.

6/599. Primary tumor of the ureteral stump following a nephrectomy for renal cell carcinoma.

    BACKGROUND: A 64-year-old man presented with asymptomatic macroscopic hematuria during a follow up for a localized renal cell carcinoma (RCC), which was treated by a right radical nephrectomy 6 years earlier. methods: x-rays and a ureteroscopic examination revealed multiple papillary tumors filling the right ureteral stump. Surgery was performed to excise the ureteral stump and bladder cuff. The tumor was histologically a grade 2-3 transitional cell carcinoma without muscle invasion. RESULTS/CONCLUSIONS: Only four patients with a ureteral stump carcinoma, including the present case, have been reported after a nephrectomy for RCC. Considering that this patient had a past history of multiple cancers, genetic or environmental factors may have contributed to the etiology of the ureteral stump tumor.

7/599. Possible development of idiopathic sclerosing encapsulating peritonitis.

    We report a rare case of idiopathic sclerosing encapsulating peritonitis (SEP). During a laparotomy before undergoing a distal gastrectomy with Billroth II reconstruction for early gastric cancer, the patient was found to have a membranous encapsulation wrapping each small bowel loop, unlike peritoneal encapsulation or typical SEP. He had complained of persistent heartburn, distension and diarrhea for 2 months in the post-operative course. The second laparotomy, which was performed to improve prolonged transit, revealed typical SEP with a thick and fibrotic membrane that encased the small bowel entirely. Stripping of the sclerosing encasing membrane, separation of the adherent loops of the proximal small bowel, and Braun's anastomosis were performed. The patient complained of epigastric fullness and diarrhea after he was relieved from the complete bowel obstruction for 45 days post-operatively. trimebutine maleate was administrated 5 months after the second operation and this markedly improved his symptoms. This case might reflect the developmental process of idiopathic SEP. In addition, the use of a motility regulator may improve symptoms related to the abnormal intestinal motility by this disease.

8/599. Correlation between clinical course and CEA levels during chemotherapy.

    In order to evaluate the correlation between clinical progress and CEA levels in gastroenteric tumours, particularly during chemotherapeutic treatment, CEA assay was performed on 330 patients (126 with gastric neoplasms, 204 with large bowel carcinoma). 175 out of these had a pre-operative assay. Moreover CEA test positivity (CEA larger than or equal to 5 ng/ml according to the technique employed by us) is higher in colon neoplasms compared with gastric neoplasms and in adenocarcinomas in comparison with undifferentiated forms; besides it depends on the pathologic stage. In colon tumours CEA test showed a higher positivity for left than for right forms (66.6% versus 38%). 240 patients were followed up with repeated CEA assays: the following observations were made: a - After radical surgery 72% of the patients shows normalized CEA values. b - In 198 patients who underwent radical surgery, not requiring chemotherapy, there was a close correlation between CEA levels and clinical evolution in 98% of the cases. c - 60 out of 68 patients (88%) submitted to chemotherapy for advanced neoplasms show a close correlation between CEA response to the chemotherapy and clinical response (p less than 0.001). These investigations stress, above all, the importance of CEA test to monitor the treatments performed (surgical and chemotherapeutic) and to adopt, eventually, more effective chemotherapeutic modalities.

9/599. Successful transvaginal repair of a rectovaginal fistula developing after double-stapled anastomosis in low anterior resection: report of four cases.

    The management of postoperative rectovaginal fistula (RVF) after low anterior resection for rectal cancer is difficult and the results are often unsatisfactory. Among 140 patients with rectal cancer who underwent low anterior resection with a double-stapled anastomosis at our hospital between 1986 and 1996, 4 (2.9%) developed RVF as a postoperative complication. The RVF developed gradually from 9 to 128 days after low anterior resection. We describe herein our technique of using a modified transvaginal approach for RVF repair with a diverting colostomy. In all four patients, the RVFs were completely eradicated with reestablishment of intestinal continuity and did not recur during the mean follow-up period of 29.5 months, ranging from 12 to 67 months. This report serves to demonstrate that emerging RVFs secondary to stapled anastomosis in low anterior resection for rectal cancer must be recognized, and that a modified transvaginal approach provides an effective method of repair.

10/599. Peritoneal sarcoidosis: case report and review of the literature.

    OBJECTIVES: This study was performed to report a patient with peritoneal sarcoidosis and review the literature for similar cases. methods: We described the clinical presentation, course, and outcome of the patient, and reviewed the medical literature from 1966 till 1997 using medline and the key words sarcoidosis, scar, and peritoneum. RESULTS: Our patient presented with a rapidly growing tumor-like mass at the site of an old appendectomy scar. laparoscopy showed a large peritoneal mass and multiple small peritoneal nodules that were found to be noncaseating granulomas by pathology. The medline search uncovered only 16 cases of peritoneal sarcoidosis, most of which presented with ascites. CONCLUSION: This case illustrates the need to consider sarcoidosis, in addition to infections and neoplasms, in the differential diagnosis of peritoneal nodules and exudative ascites.
