INTRODUCTIONThe aim of this study was to conduct an audit of the sensitivity and specificity of ultrasound, fi ne needle aspiration cytology (FNAC) and frozen section in the evaluation of thyroid malignancies in our practice.

MATERIALS AND METHODSThe medical records of all the patients who underwent thyroid surgery in a tertiary institution's General Surgery Department between January 2005 and December 2007 were retrospectively reviewed using a standardised data collection template. Results of the ultrasounds, FNACs and frozen sections were compared with the fi nal histological diagnosis.

RESULTSA total of 112 patients underwent thyroid surgery in the 3-year study period. Thyroid malignancy constituted 34 (30%) of all patients who underwent thyroid surgery. The most popular diagnostic tools used were ultrasound (81%), FNAC (69%) and frozen section (59%). The sensitivity of ultrasound, FNAC and frozen section were 41.4%, 86.4% and 68.8%, respectively. FNAC was shown to be a superior diagnostic test in detecting malignancy compared to ultrasound. FNAC was able to pick up 53% of thyroid cancers missed by ultrasound. Frozen section was able to pick up 33% of thyroid cancers that were missed by both ultrasound and FNAC.

CONCLUSIONFNAC is the most reliable tool in detecting malignancies and ought to form the mainstay for investigation of thyroid nodules. The utilisation of ultrasonographic features in the evaluation of thyroid nodules might not necessary improve the detection rate of thyroid malignancy. Frozen section helps to improve the detection rate of thyroid malignancy but further studies into its cost-effectiveness ought to be performed.

INTRODUCTIONConventionally, patients who failed endoscopic removal of common bile duct stones (CBDS) by endoscopic retrograde cholangiopancreaticography (ERCP) would be treated with open cholecystectomy and common bile duct exploration. Laparoscopic common bile duct exploration (LCBDE) is an established option for treating CBDS. The aim of this paper was to look at the feasibility of LCBDE as a salvage procedure after failed endoscopic stone extraction (ESE). The secondary endpoint was to examine the short-term outcomes of our LCBDE series.

METHODSWe retrospectively reviewed a prospective database to study the feasibility of LCBDE as a salvage procedure for failed ERCP.

RESULTSSince its inception in 2006, 43 patients had undergone LCBDE at our centre. This was achieved via a transcystic approach in 25 patients and laparoscopic choledochotomy in 15 patients. There were three conversions. Of these 43 patients, 21 had a pre-operative attempt at ESE, but only six patients had their ducts cleared endoscopically. The 15 patients who failed ESE underwent LCBDE, of which 14 achieved successful stone clearance and one required open conversion. One patient developed a bile leak, which resolved spontaneously. The median length of stay (LOS) for these 15 patients was three days, while the median LOS for the whole cohort was two days.

CONCLUSIONLCBDE has been shown to be a safe and effective method for treating CBDS, with the added bonus of a short hospital stay. Where the expertise is available, LCBDE is a safe option as a salvage procedure for failed ESE.

INTRODUCTIONLaparoscopic common bile duct exploration (CBDE) is becoming more popular in the management of choledocholithiasis due to improved laparoscopic expertise and advancement in endoscopic technology and equipment. This study aimed to evaluate the safety and short-term outcome of laparoscopic CBDE in a single institution over a 3-year period.

MATERIALS AND METHODSA retrospective review of the records of all patients who underwent laparoscopic CBDE in Tan Tock Seng Hospital between January 2006 and September 2008 was conducted.

RESULTSFifty consecutive patients, with a median age of 60 years (range, 27 to 85) underwent laparoscopic CBDE for choledocholithiasis during the study period. About half of our patients presented as an emergency with acute cholangitis (32.0%) accounting for the majority. A total of 22 (44.0%) patients underwent laparoscopic CBDE as their primary procedure while the remaining 28 (56.0%) were subjected to preoperative ERCP initially. Of the latter group, documented stone clearance was only documented in 5 (17.9%) patients. Laparoscopic CBDE via the transcystic route was performed in 27 (54.0%) patients while another 18 patients (36.0%) had laparoscopic choledochotomy and 1 patient (2.0%) had laparoscopic choledocho-duodenostomy. There were 4 (8.0%) conversions in our series. The median operative time for laparoscopic CBDE via the transcystic route and the laparoscopic choledochotomy were 170 (75-465) and 250 (160-415) minutes, respectively. For the 18 patients who underwent a laparoscopic choledochotomy, T-tube was inserted in 8 (44.4%) patients while an internal biliary stent was placed in 4 (22.2%) with the remaining 6 patients (33.3%) undergoing primary closure of the choledochotomy. The median length of hospital stay was 2 days (range, 1 to 15) with no associated mortality. The main complications (n = 4, 8.0%) included retained CBD stones and biliary leakage. These were treated successfully with postoperative endoscopic retrograde cholangiopancreatography (ERCP) with/without percutaneous drainage with no further surgery required.

CONCLUSIONLaparoscopic CBDE is a safe operation with good outcome in managing choledocholithasis. Its dividends include the numerous benefits of minimally invasive surgery. If possible, transcystic extraction is preferred to choledochotomy, as this obviates the need for biliary diversion. ERCP will still hold an important role in certain instances in the management of choledocholithiasis.
