The effect of alcohol cessation on complications following surgery | CochraneHazardous drinking affects human health in several ways, even in patients without an alcohol-related disease. These include an increased risk of surgical complications. In addition to the well known alcohol-induced disorders of the liver, pancreas, and nervous system; heavy drinking affects cardiac function, immune capacity (the body's ability to defend itself against infections), haemostasis (blood clot formation), and surgical stress responses. Cardiac insufficiency and arrhythmias (a disorder of the heart rate) are common among hazardous drinkers. Both are important risk factors for the development of postoperative complications, such as postoperative infections, cardiopulmonary complications (heart and lung complications), and bleeding episodes. Reduced immune capacity is found in most patients drinking three or more alcohol units (AU) per day.. The objective of this review was to assess the effect of ...

(1/18686) Effect of intravenous dextran 70 and pneumatic leg compression on incidence of postoperative pulmonary embolism.
The incidence of pulmonary embolism and deep vein thrombosis was measured in 50 matched pairs of patients undergoing common surgical procedures with preoperative and postoperative ventilation-perfusion lung scans and the fibrinogen uptake test. One patient in each pair was treated with intravenous dextran 70 and pneumatic leggings. The incidence of pulmonary embolism among the treated patients was significantly reduced from 24% to 8%, but the incidence of deep vein thrombosis was not significantly reduced (34% to 24%). (+info)
(2/18686) Analysis of the effect of conversion from open to closed surgical intensive care unit.
OBJECTIVE: To compare the effect on clinical outcome of changing a surgical intensive care unit from an open to a closed unit. DESIGN: The study was carried out at a surgical intensive care unit in a large tertiary care hospital, which was changed on January 1, 1996, from an open unit, where private attending physicians contributed and controlled the care of their patients, to a closed unit, where patients' medical care was provided only by the surgical critical care team (ABS or ABA board-certified intensivists). A retrospective review was undertaken over 6 consecutive months in each system, encompassing 274 patients (125 in the open-unit period, 149 in the closed-unit period). Morbidity and mortality were compared between the two periods, along with length-of-stay (LOS) and number of consults obtained. A set of independent variables was also evaluated, including age, gender, APACHE III scores, the presence of preexisting medical conditions, the use of invasive monitoring (Swan-Ganz catheters, central and arterial lines), and the use of antibiotics, low-dose dopamine (LDD) for renal protection, vasopressors, TPN, and enteral feeding. RESULTS: Mortality (14.4% vs. 6.04%, p = 0.012) and the overall complication rate (55.84% vs. 44.14%, p = 0.002) were higher in the open-unit group versus the closed-unit group, respectively. The number of consults obtained was decreased (0.6 vs. 0.4 per patient, p = 0.036), and the rate of occurrence of renal failure was higher in the open-unit group (12.8% vs. 2.67%, p = 0.001). The mean age of the patients was similar in both groups (66.48 years vs. 66.40, p = 0.96). APACHE III scores were slightly higher in the open-unit group but did not reach statistical significance (39.02 vs. 36.16, p = 0.222). There were more men in the first group (63.2% vs. 51.3%). The use of Swan-Ganz catheters or central and arterial lines were identical, as was the use of antibiotics, TPN, and enteral feedings. The use of LDD was higher in the first group, but the LOS was identical. CONCLUSIONS: Conversion of a tertiary care surgical intensive care unit from an open to closed environment reduced dopamine usage and overall complication and mortality rates. These results support the concept that, when possible, patients in surgical intensive care units should be managed by board-certified intensivists in a closed environment. (+info)
(3/18686) Colon and rectal anastomoses do not require routine drainage: a systematic review and meta-analysis.
OBJECTIVE: Many surgeons continue to place a prophylactic drain in the pelvis after completion of a colorectal anastomosis, despite considerable evidence that this practice may not be useful. The authors conducted a systematic review and meta-analysis of randomized controlled trials to determine if placement of a drain after a colonic or rectal anastomosis can reduce the rate of complications. METHODS: A search of the Medline database of English-language articles published from 1987 to 1997 was conducted using the terms "colon," "rectum," "postoperative complications," "surgical anastomosis," and "drainage." A manual search was also conducted. Four randomized controlled trials, including a total of 414 patients, were identified that compared the routine use of drainage of colonic and/or rectal anastomoses to no drainage. Two reviewers assessed the trials independently. Trial quality was critically appraised using a previously published scale, and data on mortality, clinical and radiologic anastomotic leakage rate, wound infection rate, and major complication rate were extracted. RESULTS: The overall quality of the studies was poor. Use of a drain did not significantly affect the rate of any of the outcomes examined, although the power of this analysis to exclude any difference was low. Comparison of pooled results revealed an odds ratio for clinical leak of 1.5 favoring the control (no drain) group. Of the 20 observed leaks among all four studies that occurred in a patient with a drain in place, in only one case (5%) did pus or enteric content actually appear in the effluent of the existing drain. CONCLUSIONS: Any significant benefit of routine drainage of colon and rectal anastomoses in reducing the rate of anastomotic leakage or other surgical complications can be excluded with more confidence based on pooled data than by the individual trials alone. Additional well-designed randomized controlled trials would further reinforce this conclusion. (+info)
(4/18686) Peripheral hepatojejunostomy as palliative treatment for irresectable malignant tumors of the liver hilum.
OBJECTIVE: To evaluate the concept of surgical decompression of the biliary tree by peripheral hepatojejunostomy for palliative treatment of jaundice in patients with irresectable malignant tumors of the liver hilum. SUMMARY BACKGROUND DATA: Jaundice, pruritus, and recurrent cholangitis are major clinical complications in patients with obstructive cholestasis resulting from malignant tumors of the liver hilum. Methods for palliative treatment include endoscopic stenting, percutaneous transhepatic drainage, and surgical decompression. The palliative treatment of choice should be safe, effective, and comfortable for the patient. METHODS: In a retrospective study, surgical technique, perioperative complications, and efficacy of treatment were analyzed for 56 patients who had received a peripheral hepatojejunostomy between 1982 and 1997. Laparotomy in all of these patients had been performed as an attempt for curative resection. RESULTS: Hepatojejunostomy was exclusively palliative in 50 patients and was used for bridging to resection or transplantation in 7. Anastomosis was bilateral in 36 patients and unilateral in 20. The 1-month mortality in the study group was 9%; median survival was 6 months. In patients surviving >1 month, a marked and persistent decrease in cholestasis was achieved in 87%, although complete return to normal was rare. Among the patients with a marked decrease in cholestasis, 72% had no or only mild clinical symptoms such as fever or jaundice. CONCLUSIONS: Peripheral hepatojejunostomy is a feasible and reasonably effective palliative treatment for patients with irresectable tumors of the liver hilum. In patients undergoing exploratory laparotomy for attempted curative resection, this procedure frequently leads to persistent-although rarely complete-decompression of the biliary tree. In a few cases it may also be used for bridging to transplantation or liver resection after relief of cholestasis. (+info)
(5/18686) Reconstruction for chronic dysfunction of ileoanal pouches.
OBJECTIVE: A retrospective review was performed to determine the results after surgical reconstruction for chronic dysfunction of ileal pouch-anal procedures for ulcerative colitis and familial colonic polyposis at a university medical center. METHODS: During the 20-year period from 1978 to 1998, 601 patients underwent colectomy and ileal pouch-anal anastomosis (IPAA) for ulcerative colitis, familial colonic polyposis, or Hirschsprung's disease. A J pouch was used for 351 patients, a lateral pouch for 221, an S pouch for 6, and a straight pull-through for 23. Acute complications after pouch construction have been detailed in previous publications and are not included in this study. Chronic pouch stasis with diarrhea, frequency, urgency, and soiling gradually became more severe in 164 patients (27.3%), associated with pouch enlargement, an elongated efferent limb, and obstruction to pouch outflow, largely related to the pouch configuration used during the authors' early clinical experience. These patients were sufficiently symptomatic to be considered for reconstruction (mean 68 months after IPAA). Transanal resection of an elongated IPAA spout was performed on 58 patients; abdominoperineal mobilization of the pouch with resection and tapering of the lower end (AP reconstruction) and ileoanal anastomosis on 83; pouch removal and new pouch construction on 7; and conversion of a straight pull-through to a pouch on 16. RESULTS: Good long-term results (mean 7.7 years) with improvement in symptoms occurred in 98% of transanal resections, 91.5% of AP reconstructions, 86% of new pouch constructions, and 100% of conversions of a straight pull-through to a pouch. The average number of bowel movements per 24 hours at 6 months was 4.8. Complications occurred in 11.6% of reconstructed patients. Five of the 164 patients (3.1%) required eventual pouch removal and permanent ileostomy. The high rate of pouch revision in this series of patients undergoing IPAA is due to a policy of aggressive correction when patients do not experience an optimal functional result, or have a progressive worsening of their status. CONCLUSIONS: Although occasionally a major undertaking, reconstruction of ileoanal pouches with progressive dysfunction due to large size or a long efferent limb has resulted in marked improvement in intestinal function in >93% of patients and has reduced the need for late pouch removal.

(6/18686) Risk of major liver resection in patients with underlying chronic liver disease: a reappraisal.
OBJECTIVE: To explore the relation of patient age, status of liver parenchyma, presence of markers of active hepatitis, and blood loss to subsequent death and complications in patients undergoing a similar major hepatectomy for the same disease using a standardized technique. SUMMARY BACKGROUND DATA: Major liver resection carries a high risk of postoperative liver failure in patients with chronic liver disease. However, this underlying liver disease may comprise a wide range of pathologic changes that have, in the past, not been well defined. METHODS: The nontumorous liver of 55 patients undergoing a right hepatectomy for hepatocellular carcinoma was classified according to a semiquantitative grading of fibrosis. The authors analyzed the influence of this pathologic feature and of other preoperative variables on the risk of postoperative death and complications. RESULTS: Serum bilirubin and prothrombin time increased on postoperative day 1, and their speed of recovery was influenced by the severity of fibrosis. Incidence of death from liver failure was 32% in patients with grade 4 fibrosis (cirrhosis) and 0% in patients with grade 0 to 3 fibrosis. The preoperative serum aspartate transaminase (ASAT) level ranged from 68 to 207 IU/l in patients with cirrhosis who died, compared with 20 to 62 in patients with cirrhosis who survived. CONCLUSION: A major liver resection such as a right hepatectomy may be safely performed in patients with underlying liver disease, provided no additional risk factors are present. Patients with a preoperative increase in ASAT should undergo a liver biopsy to rule out the presence of grade 4 fibrosis, which should contraindicate this resection. (+info)
(7/18686) Perioperative growth hormone treatment and functional outcome after major abdominal surgery: a randomized, double-blind, controlled study.
OBJECTIVE: To evaluate short- and long-term effects of perioperative human growth hormone (hGH) treatment on physical performance and fatigue in younger patients undergoing a major abdominal operation in a normal postoperative regimen with oral nutrition. SUMMARY BACKGROUND DATA: Muscle wasting and functional impairment follow major abdominal surgery. METHODS: Twenty-four patients with ulcerative colitis undergoing ileoanal J-pouch surgery were randomized to hGH (12 IU/day) or placebo treatment from 2 days before to 7 days after surgery. Measurements were performed 2 days before and 10, 30, and 90 days after surgery. RESULTS: The total muscle strength of four limb muscle groups was reduced by 7.6% in the hGH group and by 17.1% in the placebo group at postoperative day 10 compared with baseline values. There was also a significant difference between treatment groups in total muscle strength at day 30, and at the 90-day follow-up total muscle strength was equal to baseline values in the hGH group, but still significantly 5.9% below in the placebo group. The work capacity decreased by approximately 20% at day 10 after surgery, with no significant difference between treatment groups. Both groups were equally fatigued at day 10 after surgery, but at day 30 and 90 the hGH patients were less fatigued than the placebo patients. During the treatment period, patients receiving hGH had reduced loss of limb lean tissue mass, and 3 months after surgery the hGH patients had regained more lean tissue mass than placebo patients. CONCLUSIONS: Perioperative hGH treatment of younger patients undergoing major abdominal surgery preserved limb lean tissue mass, increased postoperative muscular strength, and reduced long-term postoperative fatigue.

(8/18686) Is early post-operative treatment with 5-fluorouracil possible without affecting anastomotic strength in the intestine?
Early post-operative local or systemic administration of 5-fluorouracil (5-FU) is under investigation as a means to improve outcome after resection of intestinal malignancies. It is therefore quite important to delineate accurately its potentially negative effects on anastomotic repair. Five groups (n = 24) of rats underwent resection and anastomosis of both ileum and colon: a control group and four experimental groups receiving daily 5-FU, starting immediately after operation or after 1, 2 or 3 days. Within each group, the drug (or saline) was delivered either intraperitoneally (n = 12) or intravenously (n = 12). Animals were killed 7 days after operation and healing was assessed by measurement of anastomotic bursting pressure, breaking strength and hydroxyproline content. In all cases, 5-FU treatment from the day of operation or from day 1 significantly (P<0.025) and severely suppressed wound strength; concomitantly, the anastomotic hydroxyproline content was reduced. Depending on the location of the anastomosis and the route of 5-FU administration, even a period of 3 days between operation and first dosage seemed insufficient to prevent weakening of the anastomosis. The effects of intravenous administration, though qualitatively similar, were quantitatively less dramatic than those observed after intraperitoneal delivery. Post-operative treatment with 5-FU, if started within the first 3 days after operation, is detrimental to anastomotic strength and may compromise anastomotic integrity. (+info)
