How long do patients wait for elective general surgery?
(9/190)
OBJECTIVE: Because data published on waiting times are largely determined from questionnaire-type surveys, which generate inconclusive opinion-based results, the objective of this study was to provide a quantitative measure of the extent and variance of waiting times among 3 elective general surgery procedures DESIGN: A prospective case study. SETTING: The Royal Alexandra Hospital, Edmonton. PATIENTS: From Feb. 1 to Mar. 15, 1999, all cases (90 patients) for each designated procedure--open or laparoscopic cholecystectomv for biliary colic or cholelithiasis, segmental resection or modified radical mastectomy for breast carcinoma and colon or rectal resection for colorectal carcinoma--were tabulated daily from the hospital elective operating lists. Data were prospectively acquired from individual surgeon offices (11 surgeons). Sixteen of the 90 patients were excluded, leaving 74 for analysis. OUTCOME MEASURES: Time in days from initial referral by the general practitioner to the surgeon (T1), time in days from the initial visit with the surgeon to operation for patients requiring no further diagnostic work-up by the surgeon (T2A), and time in days from the initial visit with the surgeon to operation for patients requiring further diagnostic work-up (T2B). RESULTS: The waiting period for patients who underwent non-cancer-related procedures (cholecystectomy) ranged from 83 to 106 days; patients with breast cancer waited an average of 24 (T1 + T2A) to 66 (T1 + T2B) days from the day of referral to the date of surgery and those with colorectal cancer waited an average of 32 (T1 + T2A) to 51 (T1 + T2B) days from the time of referral to operation (p < 0.05). CONCLUSION: This preliminary report aimed at quantitative measurement of time spent waiting for elective general surgery indicates that patients who underwent non-cancer-related procedures waited significantly longer for their surgery than patients who required procedures for cancer.

Duct-to-duct biliary reconstruction in living donor liver transplantation utilizing right lobe graft.
(10/190)
OBJECTIVE: To assess the feasibility and safety of duct-to-duct biliary anastomosis for living donor liver transplantation (LDLT) utilizing the right lobe. SUMMARY BACKGROUND DATA: Biliary tract complications remain one of the most serious problems after liver transplantation. Roux-en-Y hepaticojejunostomy has been a standard procedure for biliary reconstruction in LDLT with a partial hepatic graft. However, end-to-end choledochocholedochostomy is the technique of choice for biliary reconstruction and yields a more physiologic bilioenteric continuity than can be achieved with Roux-en-Y hepaticojejunostomy. The authors performed right lobe LDLT with end-to-end duct-to-duct biliary anastomosis, and this study assessed retrospectively the relation between the manner of reconstruction and complications. METHODS: Between July 1999 and December 2000, 51 patients (11-67 years of age) underwent 52 right lobe LDLTs with duct-to-duct biliary reconstruction and remained alive more than 1 month after their transplantation. Interrupted biliary anastomosis was performed for 24 transplants and the continuous procedure was used for 28. A biliary tube was inserted downward into the common bile ducts through the recipient's cystic duct in 16 transplants (cystic drainage), or a biliary stent tube was pushed upward into the anastomosis through the cystic duct in four transplants (cystic stent), or upward into the anastomosis through the wall of the common bile duct in 31 transplants (external stent). RESULTS: Biliary anastomotic procedures consisted of 34 single end-to-end anastomoses, 11 double end-to-end anastomoses, and 7 single anastomoses for double hepatic ducts. Overall, 5 patients developed leakage (9.6%) and 12 patients suffered stricture (23.0%). For biliary anastomosis with interrupted suture, the incidence of stricture was significantly higher in the cystic drainage group (53.3%, 8/15) than in the stent group consisting of cystic stent and external stent (0%, 0/8). While the respective incidences of leakage and stricture were 20% and 53.3% for intermittent suture with a cystic drainage tube (n = 15), they were 7.7% and 15.4% for a continuous suture with an external stent (n = 26). There was a significant difference in the incidence of stricture. CONCLUSIONS: Duct-to-duct reconstruction with continuous suture combined with an external stent represents a useful technique for LDLT utilizing the right lobe, but biliary complications remain significant.

A ten-year study on non-surgical treatment of postoperative bile leakage.
(11/190)
AIM: To summarize systematically our ten-year experience in non-surgical treatment of postoperative bile leakage, and explore its methods and indications. METHODS: The clinical data of 57 patients with postoperative bile leakage treated non-surgically from January 1991 to December 2000 were reviewed retrospectively. RESULTS: The site of the leakage was mainly the disrupted or damaged fistulous tracts of T tube in 25 patients (43.9 %), the fossae of gallbladder in 14 cases (24.6 %), the cut surface of liver in 7 cases(12.3 %), and it was undetectable in the other 2 cases. Besides bile leakage, the wrong ligation of bile ducts was found in 3 patients, residual stones of the distal bile duct in 5 patients, benign papillary strictures in 3, and biloma resulting from bile collections in 2. The diagnoses were made according to the history of surgery, clinical situation, abdominal paracentesis, ultrasonography, ERCP, PTC, MRI/MRCP, gastroscopy and percutaneous fistulography. All 57 patients were treated non-surgically at the beginning of bile leakage. The non-surgical methods included keeping original drainage unobstructed, percutaneous abdominal paracentesis or drainage, percutaneous transhepatic cholangial/biliary drainage (PTCD/PTBD),endoscopic management, traditional Chinese medicine and so on. Of the 57 patients,2 patients died,5 were converted to reoperation later, the other 50 were directly cured by non-surgical methods without any complication. The cure rate of the non-surgery was 82.5 %(50/57). CONCLUSION: Many nonoperative methods are available to treat postoperative bile leakage. Non-surgical treatment may serve as the first choice for the treatment of bile leakage for its advantages in higher cure rate, convenience and safety in practice. It is important to choose the specific non-surgical method according to the volume, site of bile leakage and patient's condition. (+info)
Tissue and serum concentrations of levofloxacin 500 mg administered intravenously or orally for antibiotic prophylaxis in biliary surgery.
(12/190)
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)
Incidence and consequence of an hepatic artery injury in patients with postcholecystectomy bile duct strictures.
(13/190)
OBJECTIVE: To compare the clinical presentation and results of treatment of postcholecystectomy bile duct injuries in patients with and without arterial injuries. SUMMARY BACKGROUND DATA: Incidence and impact of arterial injuries in patients with a postcholecystectomy biliary injury are unknown, although they are claimed to increase the risk of septic complications, difficulty of biliary repair and risk of recurrent stricture. METHODS: Fifty-five patients referred for postcholecystectomy biliary strictures and who underwent surgical repair were prospectively evaluated by celiac and superior mesenteric angiography. Circumstance and presenting symptoms of the biliary injury in patients with and without vascular injury as well as intra- and postoperative outcome in the 43 patients who underwent a Hepp-Couinaud biliary repair were compared. RESULTS: Incidence of vascular injury was 47%, the most frequent of which was right-sided hepatic artery disruptions (36%). Indication of cholecystectomy (cholecystitis, 42 vs. 45%), technique of resection (laparoscopy, 80 vs. 79%) as well as delay of recognition and presenting symptom of the biliary injury were comparable in patients with and without vascular injury. Among patients undergoing a biliary repair, the level of the biliary injury (Bismuth's type III or IV 63% vs. 54%), duration of surgery, and incidence of postoperative complications (21 vs. 21%) were also comparable in patients with and without arterial injury. One patient in each group experienced recurrent biliary stricture. CONCLUSIONS: The discovery of a disruption of the right branch of the hepatic artery should not affect management of the biliary stricture when if a Hepp-Couinaud repair is performed. (+info)
Postoperative bile leakage: endoscopic management.
(14/190)
Bile leakage is an infrequent but serious complication after biliary tract surgery. This non-randomised single centre study evaluated the endoscopic management of this problem in 55 consecutive cases. Treatment consisted of standard sphincterotomy and, if needed, subsequent stone extraction with or without endoprosthesis placement. The aim of all treatments was to facilitate bile flow into the duodenum. The biliary tract and the site of the leakage were visualised during endoscopic retrograde cholangiopancreatography (ERCP) in 98%. There was distal obstruction in 33--caused by retained gall stones in 15 patients and concomitant strictures in 18. Overall, 48 of 55 patients were treated endoscopically. An excellent outcome (clinical and radiological resolution of the bile leak) was achieved in 43 patients (90%). Five patients (10%) had continuing sepsis from which they died. Postoperative bile leakage can be diagnosed safely and effectively by ERCP and subsequent endoscopic management is successful in most cases. (+info)
Reconstructive operations on the biliary tract.
(15/190)
Fifty cases in which reconstruction of the biliary system was carried out were reviewed. In 25 cases the operation was done during the treatment of malignant neoplasms. The other 25 patients were treated for benign conditions. Delayed stricture of the biliary anastomosis occurs more frequently following operation for benign post-traumatic obstruction than following reconstruction for other conditions. This is probably a result of: (1) greater regional scarring, (2) local infection, and (3) technical imperfections in the reconstituted biliary anastomosis. Certain primary malignant tumors may be difficult to recognize by both gross and microscopic examination. In six cases of biliary obstruction resulting from malignant neoplasms in the present series, exploration had been carried out some time previously, and in four of them an erroneous diagnosis of benign biliary obstruction was made.End-to-end anastomosis of the duct above and below the point of obstruction is the method preferred in the treatment of benign biliary stricture. Intrahepatic and extrahepatic biliary-enteric anastomoses have been used successfully in selected cases. (+info)
Etiology and surgical treatment of hilar bile duct stricture.
(16/190)
OBJECTIVE: To improve the surgical effects of hilar duct stricture. METHODS: The clinical data of 76 patients with hilar bile duct stricture treated at our hospital from 1990 to 2000 were analyzed. The diagnosis was determined by triad signs of cholangitis, increase of ALP and gamma-GGT levels, dilation of intrahepatic and extrahepatic bile ducts confirmed by ultrasonography (US), computed tomography (CT), percutaneous transhepatic cholangiography (PTC) or endoscopic retrograde cholangiopancreatography (ERCP). The location of stricture was divided according to the Bismuth classification standard. RESULTS: Among the 76 patients, 46 (60.5%) suffered from injurious stricture, including 13% of Bismuth type I, 39% of type II, 19.4% of type III, and 28.2% of type IV. Inflammatory stricture was found in 28 patients, locating in the left hepatic duct (LHD) 46.4% (13/28), the right hepatic duct (RHD) 35.7% (10/28), and the common hepatic duct (CHD) 17.9% (5/28), respectively. The percentages of patients with stricture due to Mirizzi's syndrome, bile duct cyst, and sclerosing cholangitis were 9.2%, 3.9% and 2.6%, respectively. Bile duct repair procedures included biliary reconstruction with pedicled umbilical vein graft for 9.2% of the patients, and proximal cholangiojejunostomy combined with LHD and RHD plasticity for 92.2%. Seventy of the 76 patients were followed up for 2-10 years, and the excellent outcome rate was 94.7%. CONCLUSIONS: Injurious stricture is the major type of hilar bile duct stricture. Inflammatory stricture is mainly composed of RHD. Hilar bile duct stricture should be treated surgically according to various etiological features and technical principles of biliary repair. (+info)
