Objective and early diagnosis of chylous fistula in the postoperative period.

OBJECTIVE: The study goal was to evaluate whether quantitative analysis of neck drainage contents is an important parameter of objective and early diagnosis of chylous fistula (CF) in the postoperative period. STUDY DESIGN AND SETTING: We prospectively evaluated 103 consecutive neck dissections during a 2-year period at a tertiary academic referral center. Six of the patients (5.8%) had CF. The data obtained from the patients with CF were matched with normal data obtained from patients without CF. RESULTS: A statistically significant difference was found between total drainage volumes of the patients with and those without CF (P < 0.05). In almost all patients with CF, drainage levels of triglycerides and cholesterol on postoperative day 1 were higher than serum levels. The difference between the drainage levels of triglycerides and cholesterol of the patients with and without CF was highly significant (P < 0.001). CONCLUSIONS: Serum and drainage levels of triglycerides and cholesterol on postoperative day 1 can be used as objective and early predictive parameters of CF.

Malignant pleural effusions.

Pleural effusions are common in cancer patients, developing either from the malignant condition or from unrelated causes, such as congestive heart failure, pulmonary infarction, or infection. Diagnosis of malignant pleural effusion rests on demonstration of the presence of malignant cells in the pleural fluid or pleural biopsy specimen. Treatment is usually aimed at relief of symptoms rather than at the underlying malignancy. Specific therapeutic measures include thoracentesis, chest tube drainage, pleurodesis with chemicals or biologic agents, radiation and systemic chemotherapy, surgical pleurodesis, and pleuroperitoneal shunt. These should be supplemented by ancillary measures to maintain fluid and nutritional balance and prevent complications.

Retroperitoneoscopic nephrolympholysis and ureterolysis for management of intractable filarial chyluria.

PURPOSE: To evaluate the feasibility of retroperitoneoscopic lymphatic disconnection in patients with intractable filarial chyluria with the aim of reducing the morbidity of the surgery. PATIENTS AND METHODS: Two patients presented to us with intractable chyluria. They did not respond to conservative measures and endoscopic sclerotherapy. In view of the severe lipid and protein loss associated with recurrent bouts of chyluria, they merited surgical correction by lymphatic disconnection. Because this operation requires extensive mobilization within the retroperitoneum over a large area, it necessitates a large flank or midline incision. In order to reduce the incision-related morbidity, it was decided to undertake the procedure laparoscopically. The retroperitoneal route was chosen for its obvious advantages. RESULTS: Surgery was carried out uneventfully in both patients, with a mean operating time of 2 hours. The patients stayed in the hospital for an average of 2.5 days. Chyluria resolved in the immediate postoperative period, and they have been asymptomatic over a follow-up of 30 and 18 months. One patient had drainage of lymph for 5 days, which resolved spontaneously. CONCLUSIONS: The objectives of open surgery can be achieved by the minimally invasive approach of retroperitoneoscopy. The new approach significantly reduces the incision-related morbidity without compromising the principles of open surgery. We propose five important steps necessary to avoid recurrence and reduce postoperative morbidity.

GI transit and absorption of solid food: multiple effects of guar.

These experiments were undertaken in dogs with midintestinal fistulas to determine whether guar added to a meal of solid food would disrupt gastric sieving and give rise to maldigestion of solid food. Dogs were fed a standard meal of steak, chicken liver, bread, margarine, and water in which there was 0, 3.3, 7.5, or 15 g guar powder. The margarine or the liver contained [14C]triolein. Using an isotope ratio method, we determined how much [14C]triolein was absorbed at midintestine. We found that guar in a dose-related fashion increased the weight of chyme collected at midintestine, markedly reduced the percent of triolein absorbed by midintestine from 88 to 38%, and profoundly increased the passage to midintestine of large, poorly digestible pieces of steak and liver. The viscosity of the guar promoted the GI transit of large, poorly digestible pieces of food but also reduced absorption by other mechanisms.

Spurious hypocalcemia in hemodialysis patients after heparinization. In-vitro formation of calcium soaps.

Patients on long-term hemodialysis via arteriovenous fistula received heparin when the fistula needle was inserted, before a sample of blood was obtained for chemical analysis. The resultant release of lipoprotein lipase activity in vivo and continued lipolytic activity in vitro sometimes produced sufficient free fatty acid to precipitate calcium soaps. The consequent spurious hypocalcemia was most frequently observed when the patients had chylomicronemia. This cause of apparent hypocalcemia was eliminated either by immediate analyses of the blood samples or by obtaining samples before systemic heparinization.
