Concomitant cholecystectomy and coronary artery bypass.
(73/893)
INTRODUCTION AND METHODS: Cholelithiasis is a common disorder which may be present with coronary artery disease. Concomitant cholecystectomy and coronary artery bypass grafting (CABG) was performed in selected patients and retrospective study was performed to verify the safety of the concomitant surgery. RESULTS: A total of 55 patients (41 males and 14 females, mean age 64.6 8.7 years) underwent concomitant cholecystectomy and CABG between 1992 and 2001 at the Shin-Tokyo Hospital Group. Exclusion from concomitant surgery was choledocholithiasis and/or acute cholecystitis. Cholecystectomy was performed via an upper abdominal incision extending the mid-sternal incision. In 48 patients (87.3%), the gastroepiploic artery (GEA) was used for coronary revascularization. The mean number of bypass grafts was 3.6 1.2. The mean operative time, intubation period, ICU stay, and postoperative hospital stay were 376 minutes, 15.6 hours, 3.9 days, and 23.0 days, respectively. Postoperative feeding was resumed 1 day after extubation. No intra-abdominal complications, delays in feeding, abdominal wound complications or postoperative bowel obstruction were observed. CONCLUSIONS: Concomitant surgery of cholecystectomy and CABG did not increase the postoperative complications, and it is a feasible procedure of choice. (+info)

Cholecystectomy and the risk for developing colorectal cancer and distal colorectal adenomas.
(75/893)
Earlier work describes a modest association between cholecystectomy and the risk of colorectal cancer. We conducted a prospective study of 85 184 women, 36-61 years old, who had no history of cancer to evaluate whether known risk factors for colorectal cancer, including dietary history, that have not been controlled for in previous analyses can help explain the observed association. During 16 years of follow-up, 877 cases of colorectal cancer were documented and 1452 women who underwent endoscopy during the follow-up time were diagnosed with distal adenomas. After adjustment for age and other known or suspected risk factors, we found a significant, positive association between cholecystectomy and the risk of colorectal cancer (multivariate relative risk RR 1.21, 95% CI 1.01-1.46). The risk was highest for cancers of the proximal colon (RR 1.34, 95% CI 0.97-1.88) and the rectum (RR 1.58, 95% CI 1.05-2.36). However, we did not observe a significant association between cholecystectomy and distal colorectal adenomas. In this large prospective cohort study, a history of cholecystectomy appears to increase modestly the risk of colorectal cancer, even after adjustment for other colorectal cancer risk factors.

Gallstone disease in heart transplant recipients.
(76/893)
OBJECTIVE: To review the outcome of cholecystectomy after heart transplant. SUMMARY BACKGROUND DATA: The optimal timing for gallbladder surgery in heart transplant patients is controversial. METHODS: Between April 1985 and October 2000, 518 cardiac transplants were performed at Ochsner Foundation Hospital. Data gathered included ultrasound reports, cholecystectomy operative reports, gallbladder pathologic reports, complications, and deaths. RESULTS: Charts were available for 509 patients (98%), 68 (13%) of whom underwent cholecystectomy before transplantation. Of the 509, 53 (10%) had serial ultrasound examinations and 29 of the 53 (55%) developed gallstones. After transplant, 47 (9%) underwent cholecystectomy. Five cholecystectomies were performed during the immediate postoperative course. Two patients who underwent cholecystectomy had acalculous cholecystitis; one was incidental. Four patients died (one with rejection and three with sepsis). After discharge, 42 cholecystectomies were performed: 16 for biliary colic (no deaths, three patients with complications), 19 for acute cholecystitis (one death, nine patients with complications), 5 for biliary pancreatitis (1 death, 1 patient with complications), and 2 others. CONCLUSIONS: The risk of morbidity and mortality from gallstone disease is high in cardiac transplant patients, particularly immediately posttransplant. Posttransplant patients require annual ultrasound examinations to detect the onset of gallstone disease, and this risk is higher than in the general population. Gallstones alone are an indication for cholecystectomy in the cardiac transplant patient. Pretransplant cholecystectomy should be considered in clinically stable patients with gallstones. (+info)
Tissue and serum concentrations of levofloxacin 500 mg administered intravenously or orally for antibiotic prophylaxis in biliary surgery.
(77/893)
OBJECTIVES: Levofloxacin is a third-generation fluoroquinolone with a broad spectrum of antibacterial activity, comprising enterobacteria, non-fermenters, Gram-positive cocci and some anaerobic species. Members of these species are common pathogens in acute and chronic cholecystitis. This suggests that levofloxacin may be used as peri-operative prophylaxis in gall-bladder surgery. The purpose of our study was to determine serum and tissue levels of levofloxacin in cholecystectomy patients following pre-operative dosing. PATIENTS AND METHODS: Patients with gall-bladder surgery were given levofloxacin 500 mg as a single dose either intravenously (iv) or orally pre-operatively, at the treating physician's decision. Gall-bladder tissue and serum samples were collected, and drug concentrations were determined by HPLC with fluorescence detection. Additionally, all tissue samples underwent routine microbiological diagnostics. MICs for aerobic isolates were determined using the Etest. RESULTS: A total of 61 patients (48 female, 13 male) were included. The medians of the levofloxacin concentrations in serum were 11.37 mg/L (iv) and 9.65 mg/L (oral), and in gall-bladder tissue they were 15.61 mg/kg (iv) and 17.93 mg/kg (oral). Eleven pathogens were isolated from gall-bladder samples. Post-operative wound infection was observed in two of the 61 patients. CONCLUSION: Our data suggest that levofloxacin may be considered for peri-operative prophylaxis in biliary tract surgery. (+info)
Does using a laparoscopic approach to cholecystectomy decrease the risk of surgical site infection?
(78/893)
OBJECTIVE: To assess the impact of laparoscopy on surgical site infections (SSIs) following cholecystectomy in a large population of patients. SUMMARY BACKGROUND DATA: Previous investigations have demonstrated that laparoscopic cholecystectomy is associated with a shorter postoperative stay and fewer overall complications. Less is known about the impact of laparoscopy on the risk for SSIs. METHODS: Epidemiologic analysis was performed on data collected during a 7-year period (1992-1999) by participating hospitals in the National Nosocomial Infections Surveillance (NNIS) System in the United States. RESULTS: For 54,504 inpatient cholecystectomy procedures reported, use of the laparoscopic technique increased from 59% in 1992 to 79% in 1999. The overall rate of SSI was significantly lower for laparoscopic cholecystectomy than for open cholecystectomy. Overall, infecting organisms were similar for both approaches. Even after controlling for other significant factors, the risk for SSI was lower in patients undergoing the laparoscopic technique than the open technique. CONCLUSIONS: Laparoscopic cholecystectomy is associated with a lower risk for SSI than open cholecystectomy, even after adjusting for other risk factors. For interhospital comparisons, SSI rates following cholecystectomy should be stratified by the type of technique. (+info)
The fate of gallstones: traditional practice questioned.
(79/893)
AIMS: Gallstones are traditionally handed back to patients as a souvenir of their cholecystectomy. The aim of this study was to review the potential hazards of this practice, the final fate of gallstones and the patients' perception of the risks. PATIENTS AND METHODS: A total of 86 consecutive patients undergoing cholecystectomy for cholelithiasis were surveyed prospectively. An unrestricted Medline database search was performed to gather pertinent literature. RESULTS: Of the 86 patients studied, 64% took their gallstones home, out of whom 29% actually handled the stones. In 9%, gallstones were accessible to children. Of all patients surveyed, 19% thought that the stones could be harmful. No patient received any information about the potential risks. Of the study group, 35% had discarded their stones by 6 weeks and 16% were planning to discard them. The rest were unsure or had decided to keep the stones. CONCLUSIONS: Available literature establishes the presence of viable pathogenic bacteria in gallstones, but their infective potential is unknown. These bacteria are possibly more pathogenic than similar gut flora. This study has shown that gallstones are handled by a significant number of patients and are even accessible to children. The majority of patients do not consider them harmful and no information is provided to them. In this age of increasing health awareness, we recommend that patients taking their gallstones home should be informed of the potential risks. (+info)
Operative stress response and energy metabolism after laparoscopic cholecystectomy compared to open surgery.
(80/893)
AIM: To determine the least invasive surgical procedure by comparing the levels of operative stress hormones, response-reactive protein (CRP) and rest energy expenditure (REE) after laparoscopic (LC) and open cholecystectomy (OC). METHODS: Twenty-six consecutive patients with noncomplicated gallstones were randomized for LC (14) and OC (12). Plasma concentrations of somatotropin, insulin, cortisol and CRP were measured. The levels of REE were determined. RESULTS: In the third postoperative day, the insulin levels were lower compared to that before operation (P<0.05). In the first postoperative day, the levels of somatotropin and cortisol were higher in OC than those in LC. After operation the parameters of somatotropin, CRP and cortisol increased, compared to those in the preoperative period in the all patients (P<0.05). In the all-postoperative days, the CRP level was higher in OC than that in LC (7.46+/-0.02; 7.38+/-0.01, P<0.05). After operation the REE level all increased in OC and LC (P<0.05). In the all-postoperative days, the REE level was higher in OC than that in LC (1438.5+/-418.5; 1222.3+/-180.8, P<0.05). CONCLUSION: LC results in less prominent stress response and smaller metabolic interference compared to open surgery. These advantages are beneficial to the restoration of stress hormones, the nitrogen balance, and the energy metabolism. However, LC can also induce acidemia and pulmonary hypoperfusion because of the penumoperitonium it uses during surgery. (+info)
