During the past four years three patients have been seen with ischemia of the colon segment following colon interposition. Colon interposition was done for esophageal cancer in two patients and for esophageal stricture following ingestion of lye. Colon ischemia was manifested as early as two weeks in one patient and as late as eight weeks in the others. Colon ischemia presented a frank gangrene with cervical fistula or as dysphagia due to stricture formation. Dysphagia in two patients prompted mechanical dilatation of the colon segment which led to perforation in both cases. All three patients had empyemas. The management of these patients includes proper diagnosis, drainage of abscesses and antibiotic treatment, hyperalimentation and visceral arteriography to delineate the residual colon for reinterposition. Two of the three patients in the series are long-term survivors and are well.

The number of aged surgical patients is increasing due to the increase of aged people in the general population. Aged surgical patients above 65 years of age constituted about 30% of all ICU patients in our institution. Perioperative care for aged patients has now become one of the most important clinical activities in the ICU. The perioperative management for those aged patients should be performed with great care because these patients have some abnormalities in water and electrolyte metabolism. Aged patients showed decreased blood levels of atrial natriuretic peptide (ANP) and decreased creatinine clearance even in the preoperative period. The ANP level and the creatinine clearance showed significant negative correlation, indicating that one of the reasons for impaired renal function among aged patients could be the decreased ANP level in blood. The intraoperative insults to the aged surgical patients undergoing radical operation for esophageal cancer tended to be smaller compared to that in the younger patients. Intraoperative infusion volume and urinary output were also smaller in the aged group compared to those in the younger group. The postoperative infusion therapy in the ICU mainly consisted of intravenous hyperalimentation with decreased Na content and the transfusion of fresh frozen plasma. This regimen should be more suitable for the aged patients. Even though the aged and the younger group received the same infusion therapy during their postoperative ICU stay up to the 7th day, the aged patients showed the tendency of Na and Cl retention and increase in anion gap. However, these abnormalities in water and electrolyte metabolism were not so severe as to cause clinical symptoms.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied on 66 patients with esophageal cancer with preoperative enteral hyperalimentation by elemental diet, comparing with 64 patients without it, and the following results were obtained; Items such as TP, Alb, etc. in surviving patients, as well as those who died within 3 months, were worse immediately before operation than those at the time of admission when neither TPN nor ED was yet in use. In 35 of 66 patients, there were significant differences between the patients with or without postoperative complications, and who were died after surgery, in arm circumference (AC), triceps skinfold (TSF), arm muscle circumference (AMC), albumin (Alb), prealbumin (PA), retinol-binding protein (RBP) and PPD skin test. From the studies of about 60 items with the computer, the index as follow were obtained. Nutritional Assessment Index (NAI) = 2.64 AC + 0.6 PA + 3.76 RBP + 0.017 PPD - 53.8 Nutritional status of the patients was divided retrospectively broadly to three groups, good (NAI greater than or equal to 60), intermediate (60 greater than NAI greater than or equal to 40), and poor (40 greater than NAI) in preoperative period. The incidence of postoperative complications and mortality rates were reflected significantly in NAI. NAI would be useful to know prospectively the probability of all kinds of postoperative complications as well as estimating the nutritional assessment.

Because of the development in parenteral nutrition, the replacement of thyroid hormones in hypothyroid or athyroid patients under intravenous hyperalimentation has become a new problem to be considered. We tried parenteral replacement of the hormones, intravenously or by enema, in three such patients. Two patients, 54 y-o and 64 y-o females, who underwent laryngo-esophago-thyroidectomy for cervical esophageal cancer or thyroid cancer, had replacement with intravenous l-thyroxine with an initial dose of 100 micrograms/day for 9 and 22 days, respectively. Another patient, a 56 y-o female with dysphagia due to local recurrence of cervical esophageal cancer after laryngo-esophago-thyroidectomy, was given 100 mg of desiccated thyroid by enema for 8 days followed by intravenous l-thyroxine for 104 days. Serum levels of thyroxine, triiodothyronine and TSH before l-thyroxine treatment indicated severe hypothyroidism in all cases. During the first 7 days of the intravenous therapy, serum thyroxine and triiodothyronine levels increased by 0.87 +/- 0.14 microgram/dl/day and 6.7 +/- 4.7 ng/dl/day, respectively, while serum TSH levels decreased by 7.8 +/- 6.4 microU/ml/day. Plasma T4 levels reached the normal level within 7 days, and plasma T3 levels within 11 days, while it took 14 days for plasma TSH levels to decrease to the normal level. The maintenance dose checked by the normal TSH levels in a patient undergoing a long term therapy was 75 micrograms/day or 1.83 micrograms/kg of body weight/day.(ABSTRACT TRUNCATED AT 250 WORDS)

Postoperative phosphate dynamics were studied in 30 patients who underwent radical surgery for thoracic esophageal cancer and who were postoperatively nourished by total parenteral nutrition. There was a significant fall in the serum phosphate level on the 2nd and 3rd postoperative days in all patients. Postoperative hypophosphatemia was due to an increase in urinary phosphate excretion which was indicated by the fall in TRP% and TmPO4/GFR. A highly significant positive correlation was observed between the increase in urinary phosphate loss and the enhanced secretion of parathyroid hormone which was possibly triggered by surgical stress, a decrease in the serum level of calcium, the action of phosphate buffer or diuretics. All the patients except for those with postoperative pulmonary complications responded to the drop in serum phosphate by renal conservation of phosphate. A slight decrease in the serum level of phosphate was also found on the 6th postoperative day in most patients who were receiving parenteral hyperalimentation. The second fall in phosphate was due to transcellular shifts of phosphate. It is concluded that patients with postoperative pulmonary complications develop severe hypophosphatemia which should be prevented by replacement therapy with phosphate in the immediate postoperative period.

Indications of rethoracotomy after esophagectomy for esophageal cancer are reviewed in this paper. Hemothorax, pneumothorax, pyothorax and chylothorax are the main causes of rethoracotomy. Complications indicating rethoracotomy are summarized as follows: 1) Hemothorax; emergency rethoracotomy is indicated in cases of bleeding through the chest drain over 100ml/hr, which is continuing over 5 hours or in cases when normal blood pressure cannot be maintained without blood transfusion. In many cases the bleeding point is the chest wall, from the branches of the intercostal artery. 2) Pneumothorax; reoperation for pneumothorax is rare. But rethoracotomy and bullectomy or closure of fustula is indicated when a large volume of air leakage and lung collapse continues over a week. 3) Pyothorax; old pyothorax with bronchial fistula is treated by closure of fistula and plombage with omentum or muscle flap. 4) Chylothorax; chylothorax is not a frequent complication of esophageal surgery but when it occurs reoperation is not rare. In cases with 1,500ml/day or more of chyle drainage for over 5 days under fasting with intravenous hyperalimentation, rethoracotomy and ligation of thoracic duct is indicated.

Many studies, both national and international, have shown that tea has protective effects on many chronic diseases and their risk factors. In cancer prevention, our studies indicated that tea drinking could inhibit the carcinogenicity of various chemical carcinogens, including oral tumors induced by 7,12-dimethylbenz[a]anthracene (DMBA) in Golden hamsters, esophageal tumors in rats by blocking in vivo synthesis of N-Nitroso-methylbenzylamine (NMBzA), esophageal cancer induced by NMBzA in rats, precancerous liver lesions (r-GT and GST-P) induced by diethylnitrosamine (DENA) in rats, intestinal preneoplastic lesion (ACF) and intestinal tumors induced by 1,2-dimethyl-hydrazine (DMH) in rats, lung carcinoma induced by nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone(NNK) in A/J mice. Our studies have also shown that the protective effects of tea against cancer is a combined effects of various tea ingredients, among which the major ones are polyphenols and tea pigments. Based on animal studies, antioxidant properties, protection against DNA damage and modulation of immune functions were found to be the main mechanisms of anticancer effects of tea. In human trials, tea drinking showed protective effects against oxidative damage and DNA damage caused by cigarette smoking. Mixed tea drinking significantly blocked lesion progress in patients with oral mucosa leukoplakia, therefore, demonstrated its protective effects on oral cancer. Our studies have also shown effects of tea on prevention of cardiovascular diseases (CVD). For example, tea pigments was found to significantly inhibit LDL oxidation induced by Cu2+, Fe2+ in in vitro studies. In vivo studies showed that tea could prevent blood coagulation, facilitate fibrinogen dissolution, inhibit platelet aggregation, lower endothelin levels, enhance GSH-Px activities, protect against oxidated LDL-induced damage in endothelium cells, and prevent atherosclerosis of coronary arteries. The mechanisms of these protective effects of tea are possibly related to its antioxidant properties or its inhibition of lipid oxidation. Green tea and pigments was also found to inhibit cardiac hypertrophy induced by renal hypertension in rat models, whose mechanisms might, at least partly, involve its modulation on nitric oxide, angiotensin II and endothelin-1. Clinical intervention trials have indicated that tea and tea extracts decreased blood lipid, improved blood flow of coronary artery, and played an important role in atherosis inhibition and prevention. Our studies also showed that tea drinking has protective effects on diabetes. White tea drinking could significantly relieve symptoms including polyuria, polydipsia, polyphagia and weight loss in diabetic mice, decrease fasting plasma glucose level and improve glucose tolerance. In human trial, continuous white tea drinking could significantly improve symptoms of diabetic patients, such as relieve polydipsia, decrease plasma glucose levels, both fasting and 2 hours after meal, and increase insulin secretion. The effective rate for glucose lowering is 48% in clinical study.
