Abstract
BACKGROUND Staged total thyroidectomy has been advised to prevent bilateral recurrent laryngeal nerve paralysis when loss of the signal from neural monitoring is observed after dissection of the initial thyroid lobe. This is supported by expert opinion but hard evidence is lacking. A lost signal can return during surgery or, even if it persists, its positive predictive value is only in the range 60-70 per cent. The aim of the present study was to investigate the clinical outcome of patients in whom total thyroidectomy was performed following loss of signal after dissection of the first thyroid lobe. METHODS This was a prospective observational study of adult patients scheduled for neural monitoring during total thyroidectomy. The prevalence of first-side absence or loss of signal was recorded. The contralateral thyroid lobe was approached routinely. The vagus and recurrent laryngeal nerves on the first side were retested during and at the end of the contralateral procedure. RESULTS Some 462 patients were included. Loss (32 patients) or initial absence (8) of signal at dissection of the first thyroid lobe was noted in 40 patients (8·7 per cent). Total thyroidectomy was completed in 29 patients, and a change of surgical strategy adopted in 11 patients with benign disease. At retesting, 15 of 37 initially silent nerves recovered electromyographic signal after a mean(s.d.) interval of 30(14) min. Postoperative vocal cord palsy/paresis was demonstrated in 24 of 40 patients. One patient developed a bilateral paresis that could be managed conservatively. CONCLUSION After an absence or loss of signal of the recurrent laryngeal nerve following dissection of the first thyroid lobe, contralateral thyroidectomy can be performed safely, avoiding the expense, psychological burden and potential complications of a second procedure.

Abstract
Abstract
Background
Parathyroid failure is the most common complication after total thyroidectomy but factors involved are not completely understood. Accidental parathyroidectomy and parathyroid autotransplantation resulting in fewer than four parathyroid glands remaining in situ, and intensity of medical treatment of postoperative hypocalcaemia may have relevant roles. The aim of this study was to determine the relationship between the number of parathyroid glands remaining in situ and parathyroid failure after total thyroidectomy.
Methods
Consecutive patients undergoing first-time total thyroidectomy were studied prospectively, recording the number of Parathyroid Glands Remaining In Situ (PGRIS = 4 − (glands autografted + glands in the specimen)) and the occurrence of postoperative hypocalcaemia, and protracted and permanent hypoparathyroidism. Demographic, disease-related, laboratory and surgical variables were recorded. Patients were classified according to the PGRIS number into group 1–2 (one or two PGRIS), group 3 (three PGRIS) and group 4 (all four glands remaining in situ), and were followed for at least 1 year.
Results
A total of 657 patients were included, 43 in PGRIS group 1–2, 186 in group 3 and 428 in group 4. The prevalence of hypocalcaemia, and of protracted and permanent hypoparathyroidism was inversely related to the PGRIS score (group 1–2: 74, 44 and 16 per cent respectively; group 3: 51·1, 24·7 and 6·5 per cent; group 4: 35·3, 13·1 and 2·6 per cent; P < 0·001). Intact parathyroid hormone concentrations at 24 h and 1 month were inversely correlated with PGRIS score (P < 0·001). Logistic regression identified PGRIS score as the most powerful variable influencing acute and chronic parathyroid failure. In addition, a normal–high serum calcium concentration 1 month after thyroidectomy influenced positively the recovery rate from protracted hypoparathyroidism in all PGRIS categories.
Conclusion
In situ parathyroid preservation is critical in preventing permanent hypoparathyroidism after total thyroidectomy. Active medical treatment of postoperative hypocalcaemia has a positive synergistic effect.

Abstract
Abstract
Background
Staged thyroidectomy has been recommended when loss of the signal from intraoperative nerve monitoring is observed after first-side dissection of the recurrent laryngeal nerve. There is no high-quality evidence supporting this recommendation. In addition, it is not clear whether signal loss predicts postoperative vocal cord paralysis.
Methods
This was a prospective observational study of consecutive adult patients undergoing neuromonitored total thyroidectomy for either malignancy or multinodular goitre. The prevalence of first-side loss of signal was recorded. Surgery was completed, and vagus and laryngeal nerves on the first side were rechecked at the end of the procedure.
Results
Two-hundred and ninety patients were included. Loss of signal on the first side was noted in 16 procedures (5·5 per cent). Thyroidectomy was completed and, at retesting, 15 of 16 initially silent nerves recovered an electromyographic signal with a mean(s.d.) amplitude of 132(26) mcV. Mean time to recovery was 20·2 (range 10–35) min. In no patient was the signal lost on the opposite side. Only three of 15 nerves with a recovered signal were associated with transient vocal cord dysfunction.
Conclusion
After loss of signal of the recurrent laryngeal nerve dissected initially, there was a 90 per cent chance of intraoperative signal recovery. In this setting, judicious bilateral thyroidectomy can be performed without risk of bilateral recurrent nerve paresis.

Abstract
Neural monitoring is increasingly applied to thyroid surgery and yet few surgeons have received formal training in intraoperative neuromonitoring (IONM). Standardized application of neural monitoring is an expected outcome of formal training programs in IONM. This study was designed to document a systematic training course that focuses on standardized state-of-art IONM knowledge. Seventeen 1-day courses were organized by the Department of Surgical Sciences, University of Insubria Medical School (Varese-Como, Italy), between 2009-2010. The course included didactic and practical training sessions. Some specific steps and checklist identified for courses included: knowledge of IONM technology and troubleshooting algorithms; IONM anesthetic perspectives, standards of IONM equipment set up and technique. A total of 75 trainees completed a questionnaire after completion of the respective courses. Questions probed demographic data, operative IONM experience and evaluation of course content. Data gathered showed that 97% of participants had no prior experience with the standardized approach of IONM technique (i.e. stimulation of the vagal nerve). The most useful parts of the course were judged to be (a) algorithms for perioperative IONM problem solving (30%), (b) live surgery with hands-on training (25%), (c) standardization of IONM technique (25%), and (d) IONM equipment set-up (20%). Poor reimbursement for hospital thyroid procedures is the main reason of limitation of IONM technology. The course offered participants novel knowledge and training and gave participants a systematic and standard approach to IONM technique.

Abstract
BACKGROUND Although the variables that influence the development of post-thyroidectomy hypocalcaemia are now better understood, the risk factors and long-term outcome of persistent hypoparathyroidism (HPP) are poorly defined. A retrospective review of a prospective protocol for the management of post-thyroidectomy hypocalcaemia was performed. METHODS Patients with a serum calcium level below 8 mg/dl (2 mmol/l) 24 h after total thyroidectomy were prescribed oral calcium with or without calcitriol and followed for at least 1 year. Protracted HPP was defined as an intact parathyroid hormone (iPTH) level below 13 pg/ml and need for calcium medication at 1 month after thyroidectomy. RESULTS Of 442 patients (343 with goitre, 99 with carcinoma) undergoing total thyroidectomy, 222 (50.2 per cent) developed postoperative hypocalcaemia. Eleven patients were lost to follow-up. Parathyroid function recovered in 131 patients within 1 month and 80 developed protracted HPP, which was associated with lymphadenectomy, fewer than three glands left in situ and incidental parathyroidectomy. Parathyroid function recovered within 1 year in 78 per cent of patients with protracted HPP. Factors associated with late recovery of parathyroid function were higher serum calcium and low but detectable iPTH levels 1 month after surgery. These factors were associated with higher calcitriol and calcium dosages at hospital discharge. Parathyroid autotransplantation did not protect against permanent HPP. CONCLUSION Higher serum calcium levels at 1 month after total thyroidectomy are associated with recovery of parathyroid function. It is hypothesized that intensive medical treatment of hypocalcaemia-'parathyroid splinting'-may improve the outcome of patients with protracted HPP.

Abstract
Abstract
Background
The bone mineral density (BMD) response to parathyroidectomy is heterogeneous and difficult to predict. Available data come from mixed populations of men and women, of different age and degrees of disease severity, and preoperative BMD loss.
Methods
This was a longitudinal, prospective cohort study of 103 postmenopausal women with osteopenia or osteoporosis at the femoral neck site, successfully operated on for primary hyper parathyroidism. BMD and metabolic variables were recorded before and 1 year after parathyroidectomy.
Results
After surgery, there was a 1·3 per cent increase in the median BMD at the femoral neck site (0·615 versus 0·623 g/cm2; P = 0·001). Overall, positive responses were also observed at total hip (0·4 per cent) and lumbar spine (2·3 per cent) sites. Analysing the individual responses, however, only 45 (46 per cent) of 97 patients showed a significant (at least 3·7 per cent) increase in BMD at the femoral neck site compared with the preoperative value and 52 had a decreased (15) or unchanged (37) femoral neck BMD. Patients who gained BMD were younger, had more severe hyperparathyroidism and better renal function.
Conclusion
Almost half of the postmenopausal women with hyperparathyroidism and low BMD have a significant remineralization response 1 year after parathyroidectomy. Differential mineralization responses of BMD after surgery appear to be related to severity of primary hyperparathyroidism, age and renal function.

Abstract
BACKGROUND Sacral nerve stimulation (SNS) has better results and safety than other surgical procedures for faecal incontinence. This prospective study assessed the clinical effectiveness and costs of SNS at a single centre. METHODS Patients who had experienced one or more episodes of faecal incontinence were studied for up to 5 years by continence diary, anorectal manometry and quality of life questionnaires. Direct medical costs were calculated and the cost-effectiveness of the treatment was analysed. RESULTS Fifty-seven percutaneous nerve evaluations were performed in 47 patients between June 1999 and February 2006; 29 patients underwent permanent implantation. After a median follow-up of 34.7 (range 2.3-81.2) months, 25 of the 29 patients had a significant reduction in incontinence episodes; 14 patients were in complete remission. At 3-year follow-up, the mean reduction in incontinence episodes was 89 per cent. No change was observed in anal manometric values. Patients reported a significant improvement in quality of life. The introduction of SNS has an incremental cost-effectiveness ratio, below the accepted Spanish threshold. CONCLUSION The introduction of SNS to the management of faecal incontinence within the Spanish setting is both effective and efficient.

Abstract
Abstract
Background
Transient recurrent laryngeal nerve palsy affects to 5–10 per cent of patients after extracapsular thyroidectomy. This prospective study assessed the impact of surgical injury and extralaryngeal branching of the inferior laryngeal nerve (ILN) on vocal cord dysfunction (VCD).
Methods
Total thyroidectomy or lobectomy was performed in 188 patients, with 302 ILNs at risk. The anatomy of the ILN and degree of injury to the nerve, based on the Laryngeal Nerve Injury Score (LNIS), were recorded. Fibreoptic laryngoscopy was performed a mean(s.d.) of 10·6(4·1) days after thyroidectomy.
Results
Some 37·4 per cent of ILNs showed extralaryngeal branching. In all, 10·9 per cent of patients developed VCD; 4·3 per cent had paresis and 6·6 per cent paralysis. All paretic and all but one paralytic cords recovered fully after 61(17) days. VCD was more frequently associated with branched than non-branched ILNs (15·8 versus 8·1 per cent; P = 0·022). Injuries were more common in branched nerves (mean(s.e.m.) total LNIS 0·94(0·08) versus 0·51(0·05); P < 0·001). Branched nerves were more likely to be associated with VCD (odds ratio 2·2 (95 per cent confidence interval 1·1 to 4·5)).
Conclusion
Branched ILNs suffer more surgical injuries and are twice as likely to be associated with VCD.

Abstract
59 patients with suspected central venous catheter related bacteraemia (CRB), while receiving parenteral nutrition, were studied prospectively. 41 (Group 1) were managed conservatively: cultures were taken from the catheter hub lumen, skin at the catheter entry site and peripheral blood; the catheter was then heparinised and locked for 24-48 h. The catheter was withdrawn only if cultures were positive; otherwise parenteral nutrition was resumed. In 18 patients the catheter was immediately withdrawn (Group 2) and the same cultures plus tip culture were performed. 13 patients of Group 1 with positive hub or skin cultures, had their catheters removed and 12 had blood cultures matching for the same micro-organism. Negative skin and hub cultures had a negative predictive value for CRB of 96%. A positive hub culture had a 100% positive predictive value for CRB. CRB was diagnosed in 11 patients out of the 18 in whom catheters were withdrawn immediately (Group 2). Thus, 1 out of 41 catheters and 7 out of 18 catheters were removed unnecessarily in Groups 1 and 2 respectively (p = 0.001, Fisher's test). In all, 24 CRBs were documented and 15 were due to coagulase negative staphylococci. The catheter hub was the commonest origin of CRB followed by the infusate and the skin. In febrile patients on parenteral nutrition, negative skin and hub cultures accurately predict or rule out CRB and should be used more often to avoid withdrawal of sterile catheters.

Abstract
BACKGROUND The aim was to evaluate the factors determining preoperative renal dysfunction in patients with obstructive jaundice. METHODS In a prospective cross-sectional observational study, 63 patients, 27 with benign and 36 with malignant obstructive jaundice, were investigated at admission and compared with 25 healthy control subjects. Variables analysed included extracellular body water (ECW) compartment, plasma levels of aldosterone, renin, atrial natriuretic peptide, vasopressin, nitric oxide, endothelin (ET) 1 and prostaglandin E2 (PGE2), urinary nitric oxide and PGE2, serum albumin and renal function. RESULTS The metabolic profile of obstructive jaundice was characterized by a depletion of the ECW (P = 0.004), and increased plasma levels of atrial natriuretic peptide (P < 0.001), ET-1 (P = 0.044), vasopressin (P = 0.017), aldosterone (P = 0.005) and renin (P = 0.001). Increased plasma (P < 0.001) and urinary (P = 0.001) PGE2 levels were also found. Fifty-four per cent of patients had a creatinine clearance of less than 70 ml/min. In multivariate analysis, serum bilirubin, renin, ET-1, PGE2, decreased urinary sodium excretion and age were identified as predictors of renal dysfunction. CONCLUSIONS Renal dysfunction in patients with obstructive jaundice was associated with the degree of biliary obstruction, age of the patient and reduced urinary sodium excretion. These alterations were closely related to derangements in sodium- and water-regulating hormones.

Abstract
BACKGROUND Renal dysfunction in patients with biliary obstruction is associated with extracellular water depletion. This study examined the effect of preoperative saline infusion before biliary drainage on hormonal and renal functional derangements in patients with obstructive jaundice. METHODS In a randomized study, 49 patients with malignant obstructive jaundice were investigated at baseline, on the day of drainage, and at 24 h, 72 h and 7 days after internal endoscopic biliary drainage. Patients were randomized to receive (n = 22) or not to receive (n = 27) 3000 ml normal saline intravenously for 24 h before drainage. Variables analysed included extracellular water volume, creatinine clearance, and serum levels of aldosterone, renin, atrial natriuretic peptide (ANP), vasopressin and albumin. RESULTS Preoperative saline infusion produced a rise in creatinine clearance, diuresis, ANP concentration and extracellular water volume but this did not translate into better recovery of renal function after operation. Drainage produced a fall in creatinine clearance in all patients, but hormonal and renal function had recovered by 2 days after restoration of bile flow, independently of preoperative hydration. CONCLUSION Fluid administration expands the extracellular water compartment before drainage but fails to improve renal function after drainage. Definitive improvement in endocrine and renal function requires the restoration of bile flow into the duodenum.

Abstract
BACKGROUND The prevalence of enterococcal isolation and factors associated with postoperative enterococcal infection remain ill defined. METHODS A prospective longitudinal observational study was conducted of consecutive patients with a first episode of intra-abdominal infection and a positive microbiological culture who did or did not develop a postoperative septic complication involving enterococci. The prevalence of initial enterococcal isolation was determined for each focus of infection. Postoperative enterococcal infections were related to whether appropriate (piperacillin--tazobactam), suboptimal (carbapenems) or inappropriate (cefotaxime plus metronidazole) antienterococcal therapy had been administered empirically. RESULTS Enterococci were isolated in 42 (21 per cent) of the 200 patients investigated. The isolation rates were 11 per cent for community-acquired peritonitis, 50 per cent for postoperative peritonitis and 23 per cent for intra-abdominal abscesses of both origins. No enterococci were isolated from 49 patients with perforated appendicitis. Independent factors for postoperative enterococcal infection were type of intra-abdominal infection (P = 0.006), Acute Physiology And Chronic Health Evaluation (APACHE) II score greater than 12 (P = 0.04) and inappropriate empirical antibiotic cover (P = 0.05). Postoperative enterococcal infections were associated with a high mortality rate (21 versus 4 per cent; P < 0.0007). CONCLUSION Enterococci are frequently isolated from intra-abdominal infections of non-appendiceal origin and are often involved in postoperative infectious complications, particularly peritonitis. Empirical antibiotic therapy covering Enterococcus faecalis should be contemplated in some circumstances.

Abstract
OBJECTIVE To investigate myocardial function in patients with obstructive jaundice before and after internal biliary drainage. SUMMARY BACKGROUND DATA Increased plasma levels of atrial natriuretic peptide (ANP) have been found in patients with biliary obstruction. METHODS Thirteen patients with newly diagnosed obstructive jaundice and no previous heart, lung, or renal disease were studied using a Swan-Ganz catheter. Hemodynamic measurements were taken before and 4 days after internal biliary drainage. Levels of ANP and brain natriuretic peptide (BNP) were obtained and liver function tests were also determined. RESULTS Plasma levels of ANP and BNP were increased twofold to fourfold in the basal state and declined after biliary drainage. Independent variables predicting left ventricular systolic work were total bilirubin concentrations, duration of jaundice, and BNP. In addition, bilirubin concentrations correlated with pulmonary vascular resistance, mean arterial pulmonary pressure, and right ventricular systolic work. Internal biliary drainage resulted in an improvement in left ventricular systolic work. A correlation was found between decreasing ANP concentrations and increasing cardiac output. CONCLUSIONS Increased plasma levels of natriuretic peptides in patients with obstructive jaundice may reflect a subclinical myocardial dysfunction correlating with the degree of jaundice. After internal biliary drainage, there is a measurable improvement of cardiac function.

Abstract
BACKGROUND AND AIMS There seems to be no clear-cut indications for routine TPN support after major elective surgery. The present study was designed to investigate whether TPN could improve the results of standard surgical care for acute peritonitis (laparotomy plus antibiotics). ANIMALS AND METHODS Peritonitis was induced in 48 New Zealand rabbits (day -2). On day 0, appendectomy and peritoneal lavage were performed, ceftriaxone (250 mg, i.m./24 h.) was started and animals were randomly assigned to receive regular fluids (RF), glucose-based TPN (G-TPN) or isocaloric fat-based TPN (F-TPN) for 6 days. MAIN OUTCOME MEASURES Balance studies (days 1-3), s-albumin, thyroid hormones and urinary catecholamines were determined at various points of the experiment. At postmortem, wound infection, residual intra-abdominal infection and laparotomy wound breaking strength were recorded. RESULTS Peritonitis produced a fall in weight, s-albumin and T3. At day 6, weight-loss was more pronounced in RF than in G-TPN or F-TPN (-7 vs 1.5 vs -1.2%;P=0.0001) but s-albumin and T3 concentrations were similar. Diuresis (377 vs 268 vs 269 mL/3 days; P=0.01) was higher and water balance lower (373 vs 511 vs 480 mL/3 days; P=0.01) in Group RF. Although the differences were not statistically significant (P<0.2), persistent infection and wound breaking strength were slightly worse in the pooled TPN groups compared with the RF group (19 vs 6% and 542 vs 701 g, respectively). CONCLUSIONS TPN failed to improve relevant biochemical markers and clinical outcome after laparotomy for peritonitis.

Abstract
BACKGROUND Anorexia is a frequent finding in patients with biliary obstruction (BO). This study investigates the role of biochemical and hormonal factors in the pathogenesis of reduced food intake in BO and the effects of internal biliary drainage. STUDY DESIGN Sixty-two patients with BO were prospectively investigated. Transaminases, amylase, cholecystokinin, secretin, bile acids, tumor necrosis factor-alpha, and endotoxin were determined at admission. Caloric intake was quantified by a controlled diet. In a subset of 27 patients, studies were repeated after internal biliary drainage. RESULTS Sixty-six percent of patients had spontaneous food intakes below the estimated caloric requirements. Serum bilirubin, alkaline phosphatase, and cholecystokinin plasma levels were independent predictor factors for calorie intake (p = 0.0001). After internal biliary drainage, cholestasis parameters and cholecystokinin concentrations decreased significantly; this was associated with an improvement of spontaneous food intake in both benign and malignant biliary obstruction (p < 0.01 and p < 0.05, respectively). CONCLUSIONS Decreased food intake in BO was associated with the degree of obstruction and with increased cholecystokinin plasma levels. Biliary drainage improved biochemical and food intake derangements.

Abstract
Patients with obstructive jaundice (OJ) that requires surgery often have malnutrition associated with increased perioperative morbidity. This study investigated the factors influencing nutritional derangements in these patients. A series of 46 OJ patients were investigated prospectively (28 malignant tumors, 18 benign obstructions). A nutritional risk index of < 83.5 was used to define protein-calorie malnutrition. Liver function, cholecystokinin (CCK), tumor necrosis factor-alpha (TNFalpha), and endotoxin levels were determined. A multivariate analysis was performed, and an obstructive jaundice malnutrition index (OJMI) was obtained. Altogether, 22 (48%) OJ patients had malnutrition (33% with benign obstructions, 57% with malignant disease). Malnourished patients had higher serum bilirubin levels (258 +/- 120 vs. 154 +/- 62 mmol/L; p = 0.005), longer duration of jaundice (16 +/- 9 vs. 9 +/- 5 days; p = 0.03), and higher plasma levels of CCK (4.0 +/- 1.3 vs. 1.7 +/- 1.0 pmol/L; p = 0.005), alanine aminotransferase (ALT) (226 +/- 209 vs. 187 +/- 161 UI/L; p = 0.01), endotoxin (15 +/- 10 vs. 6.5 +/- 7.0 EU/L; p = 0.007), and TNFalpha (69 +/- 82 vs. 23 +/- 15 pg/ml; p = 0.008) than those without malnutrition. However, only serum bilirubin, CCK, ALT, and patient age were predictors for malnutrition by multivariate analysis. Malnutrition might be expected (95% confidence interval) in patients older than 68 years with increased bilirubin (> 290 mmol/L) and ALT (> 210 UI/L) levels that corresponded with an OJMI > 55. It was concluded that nutritional alterations in patients with obstructive jaundice were determined by the intensity of the biliary obstruction correlated with increased plasma CCK levels as well as with liver dysfunction and patient age.

Abstract
BACKGROUND/AIMS Prolonged acute-phase response and increase of cytokines have been associated with higher mortality and surgical complications. This study investigated the status of cytokines and acute-phase response markers in patients with obstructive jaundice. METHODOLOGY Forty-one patients were investigated. Endotoxin, tumor necrosis factor-alpha, interleukin-6, nitric oxide, C-reactive protein, liver enzymes, albumin and percentage of weight loss were determined at admission. RESULTS Endotoxin, interleukin-6 and C-reactive protein were significantly elevated in both benign and malignant obstructive jaundice. Increased plasma levels of tumor necrosis factor-alpha were only detected in malignant tumors (68 vs. 24 pg/mL; P < 0.001). Patients with positive acute-phase response (C-reactive protein > mean + 2 SD of controls) had greater weight loss (P = 0.02), endotoxin (P = 0.03) and interleukin-6 plasma levels (P = 0.05) than those with no inflammatory response. Prolonged biliary obstruction (> 10 days) was associated with higher weight loss (P = 0.04), tumor necrosis factor-alpha (P = 0.003) and interleukin-6 (P = 0.05) plasma levels. CONCLUSIONS A prolonged high-grade biliary tract obstruction prompted an increase in endotoxin levels, associated with a positive acute-phase response and cytokine elevation.

Abstract
Prevention of catheter-related bloodstream infections is critically dependent on an accurate knowledge of the two main routes by which intravascular devices become contaminated: the extraluminal (skin-related) and the intraluminal (hub-related) routes. Extraluminal catheter seeding results from infection of the catheter entry site by microorganisms and leads to bacteremia most often during the week following catheter placement. The main ways of preventing it are appropriate skin disinfection and the adoption of maximal antiseptic barriers at the time of catheter insertion. Avoiding the internal jugular and the femoral veins, whenever possible, will reduce the likelihood of bacteremia. Intraluminal contamination is the consequence of improper handling of the catheter hub at the time of connection and disconnection of the administration set. It is the most common origin of catheter infections after the first week of catheter placement. Multiple-lumen catheters, side-ports and multipurpose catheters particularly increase the risk of endoluminal contamination. To prevent it, strict asepsis should be observed in hub handling and hubs should be protected against environmental soiling with an antiseptic impregnated gauze at all times. New technology is available for prevention of catheter infections: antibiotic and antiseptic-coated catheters, antiseptic hubs, disinfecting caps and flushing solutions are currently undergoing scientific assessment.

Abstract
OBJECTIVES the aim of this study was to assess the severity and type of nutritional deficiencies observed in patients with benign and malignant obstructive jaundice (OJ). METHOD in this prospective cross-sectional study 51 patients with OJ (21 with benign and with 30 malignant obstruction) were investigated. Nutritional status was assessed by anthropometric parameters (ideal body weight, midarm muscle area and skinfold thickness), visceral proteins, creatinine height index and total lymphocyte count. Observed values in patients with OJ were normalized to the percentage value of the lower limit of normal (obtained from 17 healthy subjects matched for age and sex) and averaged to obtain a total score for protein-energy malnutrition. RESULTS forty-two (82%) patients with OJ had protein-calorie malnutrition (PCM). Malnutrition was mild in 55%, moderate in 35% and severe in 10%. Severity of PCM was associated with intensity (p < 0.05) and duration of jaundice (p < 0.01). Kwashiorkor (74%) was the dominant type of malnutrition. PCM was common in benign (71%) as well as in malignant obstruction (90%), but the total score (92 +/- 20 vs 80 +/- 19; p < 0.05) and the proportion of mild PCM in patients with benign obstruction (80% vs 41%, p < 0.01) was significantly higher than in patients with malignant tumors. CONCLUSIONS a high percentage of patients with OJ had PCM. The degree of nutritional alteration was associated with the intensity of jaundice. Malnutrition was equally prevalent among patients with benign obstructions and patients with malignant causes of biliary obstruction, although it was more severe in the latter. Acute malnutrition (kwashiorkor) was the dominant type of malnutrition in both groups of patients.

Abstract
Postoperative renal dysfunction in obstructive jaundice (OJ) patients has been associated with hypovolemia and depletion of the extracellular water compartment (ECW). The aim of the study was to evaluate the preoperative status of body compartments in OJ patients measured by two methods. In a prospective study 39 OJ patients (11 benign and 28 malignant obstructions) were investigated, with 15 healthy subjects used as a control group (CG). Bioelectrical impedance analysis (BIA) determinations and values derived from anthropometric measurements were used to assess body compartment status. The coefficient of variation of BIA was below 4% in both OJ and CG subjects. No differences were found in intracellular water. However total body water (TBW) and ECW were reduced in OJ patients (50.5 +/- 4.6 vs. 56 +/- 8% body weight, p = 0.05; and 21 +/- 4.5 vs. 23.8 +/- 2.5% body weight, p < 0.05, respectively). There were no differences between benign and malignant obstructions. Seventy four percent of OJ patients had an ECW volume below the mean +/- 2 SD in the CG subjects. Anthropometric and BIA determinations correlated closely for TBW measurements in both CG (r = 0.92, p < 0.001) and OJ patients (r = 0.91, p < 0.001). Bland-Altman analysis also showed that for TBW the BIA was in agreement with anthropometry. In the present study, BIA offered a good correlation with anthropometric determinations and was a reliable method for body fluid disturbances assessment in jaundiced patients.

Abstract
Catheter-related bloodstream infections (CBIs) rank among the most frequent and potentially lethal nosocomial infections. Intravascular devices become contaminated on the outer surface during nonaseptic insertion or maintenance of the catheter exit site or endoluminally during hub manipulation. CBI is heralded by spiking fever, malaise and rigors and should be promptly diagnosed to prevent endocarditis and septic metastasis. In about two-thirds of the cases the offending organisms are coagulase-negative staphylococci; Staphylococcus aureus, gram-negative bacilli, and Candida sp. are responsible for one-third of these infections and carry a worse prognosis. Diagnosis of CBI relies on proper bacteriologic techniques, some of which can be performed in situ avoiding withdrawal of the device. Prevention strategies should aim at avoiding extra- and endoluminal contamination and should be based on three main pillars: maximal aseptic barriers at insertion, appropriate site maintenance, and junctional (hub) care and protection. Treatment includes catheter withdrawal and appropriate antibiotic coverage. For long-term cuffed catheters, local treatment with intraluminal administration of antibiotics is effective and can save a significant number of catheters, particularly those colonized by coagulase-negative staphylococci.

Abstract
OBJECTIVE To evaluate the influence of internal drainage on status of nutritional markers in patients with obstructive jaundice. DESSING: Prospective longitudinal study. SETTING University hospital, Spain. SUBJECTS 39 patients with obstructive jaundice (18 benign and 21 malignant obstructions). INTERVENTIONS Nutritional state was assessed before and 10 days after endoscopic drainage. MAIN OUTCOME MEASURES One anthropometric (body weight <95% of ideal) and two biochemical (albumin <35 g/L and prealbumin < 170 mg/L) as an indication of protein calorie malnutrition. Retinol binding protein and transferrin concentrations, total lymphocyte count, and nutritional prognostic index (NPI) were also measured. RESULTS Thirty patients (77%) had protein calorie malnutrition. After internal drainage, 6 patients with benign obstruction and 11 with malignant tumours remained malnourished. No anthropometric variables or concentrations of proteins with long half-lives were affected by drainage. However, prealbumin (p < 0.01) and transferrin (p < 0.01) concentrations, and total lymphocyte count (p < 0.001) increased significantly in both groups. NPI also improved significantly after drainage from 43 (9) compared with 37 (5) in benign obstructions (p < 0.05) and 58.7 (14) compared with 52 (12) in malignant (p < 0.05), although in the latter group the mean nutritional risk index remained high. CONCLUSIONS Concentrations of some of the visceral proteins studied (prealbumin and transferrin) improved 10 days after internal biliary drainage for both benign and malignant obstruction. However, many patients with malignant tumours remained malnourished with a high nutritional risk index.

Abstract
INTRODUCTION Obstructive jaundice is often accompanied by protein-caloric malnutrition. The objective of the present study is to analyze the incidence and the degree of alterations in the food ingestion of patients with obstructive jaundice. MATERIAL AND METHODS In a prospective, cross-sectional study 50 patients with obstructive jaundice (19 benign and 31 malignant) were evaluated. The anorexia was evaluated using Welch's test (subjective evaluation) and by means of quantifying the caloric ingestion. An anthropometric parameter (ideal weigh < 95%) and two biochemical ones (albumin < 3.5 g/dl and pre-albumin < 17 mg/dl) were used to define the degree of malnutrition. RESULTS 96% of the patients presented alterations in the Welch test and in 72% of the patients the caloric ingestion was below the estimated needs. Overall, the ingestion of food was reduced by 76.3 +/- 30% of the estimated needs (84.7 +/- 28% in the benign cases and 70.9 +/- 32% in the malignant cases). Both the Welch test (r = 0.59; p = 0.01) and the caloric ingestion (r = 0.53; p < 0.001) were inversely correlated with the serum bilirubin. In patients with malnutrition criteria, the caloric ingestion was reduced by 30% against the 12% reduction in the non-malnourished patients (p < 0.05). There was a direct correlation between the two methods used in the assessment of the anorexia (r = 0.71; p < 0.001). CONCLUSIONS Obstructive jaundice is associated with an important reduction in the caloric ingestion, and this is manifested in both biliary obstructions of a benign origin, and in those of neoplasic origins.

Abstract
BACKGROUND Immunosuppression associated with homologous blood transfusion was first observed in renal allograft transplantation. Clinical effects of transfusion-induced immunosuppression in surgical patients have been debated in the literature for more than a decade with contradictory results. OBJECTIVE To investigate whether homologous blood transfusions significantly affect postoperative septic morbidity and mortality in patients undergoing elective surgery for gastric cancer. DESIGN Case series. SETTING Hospitalized care. PATIENTS The hospital records of 209 patients who underwent elective surgery for gastric cancer at the Department of Surgery of the Hospital del Mar, Autonomous University of Barcelona in Spain, and at the Department of Surgery of the Catholic University of Rome in Italy from April 1984 to December 1990 were reviewed, and 179 patients were included in the study. MAIN OUTCOME MEASURES The following variables were entered into univariate and multivariate analyses to identify factors potentially affecting postoperative septic morbidity: demographic data, weight loss, preoperative serum albumin level and lymphocyte count, type and duration of operative procedure, amount and timing of blood transfusion, and stage of disease. RESULTS Univariate analysis showed that a large quantity of blood transfused (> 1500 mL) and transfusion in the postoperative period (group C) were associated with a worse clinical outcome. Postoperative transfusion was an independent predictor of septic morbidity in multivariate analysis. CONCLUSIONS Despite transfusion-induced immunomodulation, homologous blood transfusion should not be considered a risk factor for postoperative septic morbidity in patients undergoing elective major abdominal surgery. The timing-response relationship between transfusions and septic morbidity in multivariate analysis may be the effect of uncontrolled confounders such as variation of volemia induced by stress response in patients who were developing or had just developed infectious complications.

Abstract
BACKGROUND The empiric antibiotic treatment of intraabdominal infections is in constant evolution. Monotherapy appears to be a desirable goal because of the simplicity of its administration, lack of toxic effects and wide spectrum. PATIENTS AND METHODS A multicentre, prospective, randomized, open study was carried out to compare two antibiotic regimens in the treatment of intraabdominal infections in patients undergoing surgery. Ninety-eight consecutive patients were randomly allocated into two groups. One group (GM, n = 51) received meropenem (1 g/8 h) and the other (GCM, n = 47) a combination of cefotaxime (2 g/8 h) plus metronidazol (0.5 g/8 h). Clinical and bacteriological responses were assessed at the end of treatment and at 2-4 weeks. RESULTS The severity of patients as assessed by the APACHE II score was similar in both groups (GM: 7.2 and GCM: 8.1). Three patients in each group could not be evaluated due to premature interruption of treatment or deviation from the protocol. The mean duration of treatment was 7.4 days in GM and 7.9 days in GCM. A satisfactory clinical response was obtained in 95% of patients in both groups. 31 patients (61%) in GM and 26 patients (55%) in GCM were bacteriologically evaluable. Bacteriological erradication was achieved in 94% of patients in GM and in 92% of patients in GCM. CONCLUSION Meropenem is a good alternative for single antibiotic therapy in intraabdominal infections of moderate severity.

Abstract
Portal cavernomatosis consists in the substitution of the portal vein by many fine, twisting venules leading to the liver. This phenomenon is produced as a consequence of anterior thrombosis of the portal vein and is associated with chronic pancreatitis, cancer of the pancreas, intraabdominal sepsis and cholelithiasis. The symptomatology may be nul or present as obstructive jaundice or portal hypertension. Diagnosis is made by Doppler echography. The treatment is portal shunt when symptomatology is produced. In patients with cholelithiasis requiring surgery, the shunt is advised prior to biliary surgery since perioperative hemorrhage, if present, may be incoercible as in the case herein described. We present a 84-year-old woman with portal cavernomatosis the etiology of which was a hydatidic cyst located in the hepatic bifurcation and treated with mebendazol 10 years previously. This etiology has not been previously reported.

Abstract
BACKGROUND Emergency operation in the elderly carries a high risk of death. We investigated the incidence of euthyroid sick syndrome (ESS) and associated nutritional and endocrine abnormalities and their relationship to postoperative outcome in this population. METHODS Sixty-six patients older than 70 years of age requiring emergency operations were assessed before any therapeutic intervention. Values for thyroid hormones, catecholamines, cortisol, interleukin-6, interleukin-1, C-reactive protein, and the Acute Physiology and Chronic Health Evaluation II score were determined. Nutritional assessment was carried out. Mortality rates and duration of hospital stay were related to ESS and albumin concentrations. RESULTS ESS was diagnosed in 34 patients (51.50%) and was associated with worse Acute Physiology and Chronic Health Evaluation II scores (10.9 vs 8.6; p = 0.004), hypoalbuminemia (34.7 vs 40.8 gm/L; p = 0.0001), lower triceps skinfold (11.8 vs 14.6 mm; p = 0.03), and higher cortisol and norepinephrine levels (937 vs 741 nmol/L [p = 0.04] and 358 vs 250 pg/ml [p = 0.02], respectively), interleukin-6 plasma concentrations (347 vs 113 pg/ml; p = 0.01), death rate (20% vs 0%; p = 0.02), and length of hospital stay (17.2 vs 11.8 days; p = 0.03). A serum albumin level less than 35 gm/L was virtually always associated with ESS. CONCLUSIONS ESS is highly prevalent in the elderly with acute surgical problems and is associated with poor nutrition, higher sympathetic response, and worse postoperative outcome. The serum albumin level at admission is a specific marker of ESS.

Abstract
BACKGROUND Biliary obstruction in the rabbit causes increased release of atrial natriuretic peptide (ANP). Circulating bile, raised biliary pressure or absence of bile in the duodenum may be implicated in this hepatocardiac syndrome. METHODS An experimental model was developed to elucidate the mechanism linking obstructive jaundice and increased plasma ANP. Hepatic and renal function, biliary tree pressure and ANP plasma concentrations were investigated in conscious rabbits 4 and 24 h after common bile duct ligation, biliovenous shunting or external drainage via a biliary fistula. RESULTS Bilirubin concentration increased after bile duct ligation and creation of a biliovenous shunt. Plasma creatinine increased abruptly in rabbits with a biliovenous shunt. At 4 h, the ANP increase in animals with a biliovenous shunt was ninefold that observed after bile duct obstruction while no change was noted after external biliary diversion (mean 350 versus 45 versus 9 fmol/l; P < 0.01). Relief of biliary tree obstruction was associated with a return of ANP levels towards basal normal values. CONCLUSION Raised plasma ANP in obstructive jaundice is not the result of an increased biliary pressure per se or absence of bile in the proximal duodenum but of the passage of bile components to the circulation.

Abstract
BACKGROUND Hypovolaemia may cause renal dysfunction in obstructive jaundice. This study investigated whether, in patients with obstructive jaundice: (1) atrial natriuretic peptide (ANP) is increased; (2) fluid-regulating hormones are altered; and (3) biliary drainage improves fluid homoeostasis. METHODS Forty-three patients with obstructive jaundice were investigated. A renal profile was obtained and levels of ANP, renin, aldosterone and vasopressin were determined. In a subset of 18 patients, studies were repeated 3 days after endoscopic biliary drainage and changes in extracellular volume were measured. RESULTS Creatinine clearance was impaired in ten of 30 patients. Patients with obstructive jaundice had higher mean levels of ANP (118 versus 40 pg/ml, P = 0.0001) and aldosterone (156 versus 43 pg/ml, P = 0.0001) than matched controls. Increased renin levels were observed in ten of the 43 patients and were associated with impaired creatinine clearance. After biliary drainage ANP concentration decreased (110 versus 67 pg/ml, P = 0.004) as well as aldosterone level (182 versus 85 pg/ml, P = 0.0002) and the mean extracellular volume increased (20.5 versus 23.1 per cent of body-weight, P = 0.001). CONCLUSION Plasma ANP concentration is increased in obstructive jaundice. Endocrine markers of hypovolaemia are activated in obstructive jaundice. After biliary drainage there is an improvement of endocrine and fluid derangements.

Abstract
Total parenteral nutrition may induce harmful water and sodium retention. Few efforts have been made to elucidate the mechanisms of this deleterious response to total parenteral nutrition. In this review we discuss the different factors involved in its pathophysiology and possible changes in total parenteral nutrition regimes in order to modulate such a response: reduction of the proportion of non-protein calories given as glucose, restriction of water and sodium, and the possible benefits of pharmaceutical nutritional therapy with glutamine and growth hormone.
