Lipomatosis of the ileocecal valve leading to episodes of partial small bowel obstruction.
The cases of two female patients with lipomatosis of the ileocecal valve inducing episodes of intestinal obstruction are presented. A barium enema with air contrast was performed in patient 1; patient 2 was operated on to treat ileus. Resection of the fatty tissue from the ileocecal valve was performed at operation, after histologic diagnosis on frozen section. These cases suggest that limited resection removing fatty tissue is effective and preferable to more radical resection.

Peritonitis associated with continuous ambulatory peritoneal dialysis: the pseudo-surgical abdomen.
In this work, 12 patients undergoing continuous ambulatory peritoneal dialysis with peritonitis showing clinical symptomatology of "acute surgical abdomen" were studied. The infective cause of peritonitis was Staphylococcus epidermidis (eight cases) and Staphylococcus aureus (four cases). All patients, under strict and continuous observation, were managed with conventional chemotherapy and showed improvement within 6 to 24 hours. The need of prompt recognition and correct evaluation of this condition by surgeons familiar with it is emphasized in order to avoid an unnecessary surgical procedure.

Combination of serum carcino-embryonic antigen and C-reactive protein--a useful test in preoperative staging of colorectal cancer.
The value of the simultaneous estimation of serum carcino-embryonic antigen (CEA) and C-reactive protein (CRP) concentrations in staging patients with colorectal neoplasias was evaluated. The study included 95 patients with benign or malignant epithelial tumors of colon and rectum. The simultaneous negative values of CEA and CRP were able to exclude stage D tumors with a specificity of 92.6% (P less than 0.001). Simultaneously positive values of CEA and CRP were able to diagnose stage C or D tumors with a specificity of 92.1% (P less than 0.001). It is concluded that the combination of CEA and CRP tests can substantially contribute to the preoperative staging and assessment of the extent of colorectal cancer.

Value of serum acute-phase reactant proteins and carcinoembryonic antigen in the preoperative staging of colorectal cancer. A multivariate analysis.
In 55 patients with benign or malignant neoplasias of the large bowel, serum carcinoembryonic antigen (CEA), C-reactive protein (CRP), alpha 1-antitrypsin (AAT), alpha 1-acid glycoprotein (AAG) levels, and the percentage of serum protein electrophoretic components were measured. Statistical analysis showed significant correlations between serum CEA, CRP, AAG, and AAT levels and the percentage of serum beta-globulins with the stage of the disease. Multivariate discriminant analysis gave a final prognostic model that included serum CEA, CRP, and AAT levels and the percentage of the serum beta-globulins with a significance of P less than 0.000001. The authors conclude that the serum acute-phase protein levels, in combination with serum CEA concentrations, have a definite role in the preoperative staging of large bowel cancer.

Adenomyoma of the common bile duct.
Adenomyomas are rare pseudotumors of the extrahepatic biliary tract. Their microscopic appearance does not differ significantly from similar malformations of the peritoneal cavity. We describe a patient who presented with obstructive jaundice and who was treated successfully with a surgical resection and a hepaticojejunal anastomosis.

[Changes in free thyroid hormones after epidural anesthesia].
The changes of FT4 and FT3 hormone levels were measured in 14 patients who were submitted to various light operations after epidural anesthesia. The FT3 changes were similar to those usually detected after general anesthesia, a fact that leads to the hypothesis that the afferent stimuli are not the only responsible for the thyroid hormone changes after stress.

Unusual primary locations of hydatid disease. Case report.
Two unusual cases of primary hydatid disease are described. In one of them a retroperitoneal cyst, presenting as a palpable abdominal mass, was strongly adherent to the inferior vena cava and dislocated the right kidney. Partial cystectomy and drainage were performed. The other cyst, of the right ischiorectal fossa, was initially misinterpreted as a perineal of sciatic hernia. It was completely removed. No other site of hydatid disease was found and the patients remain well 3 and 4 years postoperatively.

The incidence of postoperative hernia as related to the site of insertion of permanent peritoneal catheter.
Fifteen per cent of patients with end stage renal insufficiency are being treated in Greece with continuous ambulatory peritoneal dialysis (CAPD). Postoperative hernia, which is mostly incisional, is a complication which may compromise the efficacy of the method. We present our experience on patients undergoing CAPD, concerning this complication.

Serum and bile digoxin levels in patients subjected to cholecystectomy with or without choledochostomy.
Digoxin levels were measured perspectively in the serum of 12 patients subjected to cholecystectomy and in serum and bile (Kehr) of 15 patients who underwent cholecystectomy plus choledochostomy in order to assess adequate digitalization. All patients were volunteers with no cardiac problems. In the cholecystectomy group serum digoxin levels increased in all patients from the second to the fourth postoperative day (P = 0.0001), while in patients with choledochostomy both serum and bile digoxin levels displayed wide variations. This last finding was associated with signs reflecting inadequate digitalization, probably due to significant digoxin losses through the choledochostomy.

Prophylactic cholecystectomy during splenectomy for beta thalassemia homozygous in Greece.
The impact of prophylactic cholecystectomy upon early mortality and morbidity of splenectomy for patients with beta TH H was investigated. The results of our study suggested that it is a safe procedure that is not associated with any increase in operative mortality and postoperative complications. This was true even when beta TH H was complicated by pigment cirrhosis and ascites. In view of increasing longevity of those patients with beta TH H, as well as the increased risk for gallstones even after splenectomy, we recommend the use of prophylactic cholecystectomy as a standard approach for all patients undergoing splenectomy for beta thalassemia homozygous.

Postoperative changes in serum bromine value.
The changes in bromine levels in the blood serum of 40 patients who were operated upon are discussed herein. The results of this study demonstrate that all patients who received anesthetics rich in bromine (halothane and Fluothane) have an increase in serum bromine levels postoperatively. Eight of ten patients with high serum bromine levels postoperatively had intense symptomatologic findings which could be attributed to an instance of acute brominism.

Serum phosphate levels in acute bowel ischemia. An aid to early diagnosis.
Serum phosphate levels were studied in 18 patients with acute intestinal infarction as proved by laparotomy. Serum phosphate was increased preoperatively (6.12 +/- 0.75 mg/dl) in 94.4 per cent of cases. False-positive results were not recorded. The rise in phosphate was observed 4-12 hr (6.82 +/- 2.65) after the beginning of symptoms and was significantly higher when compared with both normal limits (3-5 mg/dl) and phosphate levels of 24 patients with acute abdominal conditions not associated with intestinal ischemia. This study suggests that determination of serum phosphate should be used as screening method for early detection and treatment of patients with acute intestinal ischemia.

Long term consequences of bacterial colonization of the biliary tract after choledochostomy.
We studied 48 patients--36 who underwent cholecystectomy and choledochotomy-choledochostomy for cholesterol gallstones and 12 patients as controls who underwent different types of extrabiliary operations. In our material, we observed that, in a high proportion of instances, infected bile during the early postoperative period remained contaminated for six months postoperatively--in an obviously unobstructed bile duct. In patients in whom Escherichia coli was isolated both early and late postoperatively, a statistical significancy was found. This phenomenon consists of a favorable condition for precipitation of calcium bilirubinate, triggering new pigment stone formation.

The influence of corticosteroids on ileostomy discharge of patients operated for ulcerative colitis.
The ileostomy output and electrolyte loss was studied in 23 patients undergoing operation for ulcerative colitis, to determine corticosteroid influence. Ten patients did not use corticosteroids and 13 patients received postoperatively 400 mg hydrocortisone intravenously for 4 to 5 days followed by 90 mg prednisone per os thereafter. Ileostomy volume and electrolyte concentration and total loss were measured on the 4th and 8th postoperative days. Patients on corticosteroids presented with a reduction of volume lost from the ileostomy (P less than 0.001), lower sodium concentration and total loss (P less than 0.00001), higher potassium concentration (P less than 0.00001) with similar total loss (P is not significant) and higher calcium concentration (P less than 0.00001) but lower total loss (P less than 0.05). It is concluded that corticosteroid administration influences significantly both volume and electrolyte loss due to the ileostomy discharge in patients operated for ulcerative colitis, suggesting a need for careful maintenance of fluid and electrolyte balance in the early postoperative period.

The effect of preoperative treatment with cimetidine on postoperative wound sepsis.
The results of preoperative treatment of uncomplicated duodenal ulcer patients with Cimetidine are presented. Cimetidine given preoperatively increases the pH of gastric aspirates and alters the bacterial flora of the stomach at the time of operation, resulting in an increased incidence of postoperative wound sepsis. Discontinuing Cimetidine 2 days before surgery is a safe step against the risk wound sepsis.

A comparative study of trace elements in normal and cancerous colorectal tissues.
Quantitative study of the Zn, Cu, K, Rb, Mn, Pb and Ni trace elements by the x-ray fluorescence method in normal and cancerous tissue samples, obtained from 18 patients suffering from cancer of the colon and rectum, shows that cancerous tissues exhibit statistically higher K, Rb, and Cu concentration than corresponding normal tissues. There are evidences that also Ni and Pb are elevated in cancerous tissues. Finally Zn and Mn do not show any appreciable difference in normal and cancerous tissues.
