    ABSTRACT: Background In thyroidectomy, little has been reported on the differential recurrent laryngeal nerve (RLN) palsy rates between the left and right sides. Even less is known about the potential differences causing these differential rates. This study reports the left versus right RLN palsy rates of total thyroidectomy cases in a single institution, relating them to the comparative stiffness of the left and right porcine RLNs. Computed stress modelling was also used to estimate the differential levels of tension within each RLN.Methods For the comparison of the left and right RLN palsy rates, 1926 cases of total thyroidectomy (between 2007 and 2013) from the Monash University Endocrine Surgery Unit were included. Stiffness of porcine RLNs was experimentally determined by measuring nerve extension against incremental increase in load. Additionally, the tension of intraoperatively stretched RLNs was estimated by computer modelling.ResultsThe left RLN had a palsy rate of 0.9% (18/1926), which was significantly lower (P = 0.025) than the right RLN palsy rate of 1.8% (34/1926). The left porcine RLN was 22% stiffer than the right RLN (P = 0.004). The stress modelling estimated that at the apex of the artificial RLN genu during anteromedial rotation of the thyroid lobe, the right RLN experiences twice the tension experienced by the left RLN.Conclusion The stiffer left RLN and the higher tension generated in the right RLN during thyroidectomy may jointly contribute to the higher right RLN palsy rate.

    ABSTRACT: Although right colonic diverticulitis is more common than sigmoid diverticulitis, and its incidence has been increasing in Asian countries, there is no definitive treatment strategy for right colonic diverticulitis. This retrospective clinical study assessed the effect of conservative management in patients with right colonic diverticulitis. Of the 169 patients who were diagnosed with right colonic diverticulitis at Chonbuk National University Hospital, South Korea, from 2005 to 2012, 152 patients evaluated by abdominopelvic computed tomography (CT) and managed conservatively were included. CT findings were categorized by modified Hinchey classification, with stages Ib, II, III and IV, as well as fistula and obstruction defined as complicated diverticulitis. Factors associated with recurrence of diverticulitis were determined. The mean age of 152 patients (87 males, 65 females) was 42.9 ± 13.8 years, median follow-up interval was 61 months (range, 17-113 months). At diagnosis, five patients (3.3%) had complicated diverticulitis. After treatment of first attack, 15 patients (9.9%) experienced recurrence of right colonic diverticulitis, including 10 (6.6%) within 12 months. Fourteen of these patients were successfully treated conservatively, whereas one failed conservative management and required surgical resection. Statistical analysis found no variables related to recurrence of right colonic diverticulitis. Right colonic diverticulitis has a low rate of complicated diverticulitis at first attack and a low recurrence rate, with most recurrences being uncomplicated. Therefore, conservative management is effective in patients with right colonic diverticulitis. Close follow-up of patients for 12 months is required because most recurrences may occur within 12 months. © 2015 Royal Australasian College of Surgeons.

    ABSTRACT: Many surgical techniques have been described for the treatment of pilonidal sinus, yet rates of recurrence and prolonged wound healing remain high and consensus on the optimal technique is lacking. This retrospective study evaluates outcomes of the use of the house advancement flap in the treatment of pilonidal sinus including time to wound healing, sinus recurrence, wound infection and flap necrosis. Thirty-three consecutive patients who underwent excision and house advancement flap for pilonidal sinus, of whom seven patients (21%) had recurrent pilonidal sinus disease following previous surgical intervention, were reviewed retrospectively. Follow-up ranged from 4 to 59 months (mean 28 months). All 33 patients completed a follow-up survey. Age at time of operation ranged from 14 to 44 years with a mean of 25 years. No patients developed wound infection or flap necrosis. Four patients (12%) failed to achieve primary wound healing; mean time to wound healing for the remaining 29 patients was 62 days. Recurrence of pilonidal sinus occurred in eight patients (24%), at a mean time of 22 months post-operatively. The house advancement flap achieves primary wound closure in almost 90% of cases with few acute post-operative complications. However delayed wound healing and sinus recurrence remain issues with this technique and it appears to have little advantage over other primary closure techniques. © 2015 Royal Australasian College of Surgeons.

    ABSTRACT: In screening, the distinction between phyllodes tumour (PT) and fibroadenoma (FA) is imprecise, often needing surgery. In this retrospective cohort study and literature review, we wished to (i) present our experience with PT diagnosed among screening participants; (ii) identify discriminating features between FA and PT; (iii) assess the efficacy of cancer screening in identifying PT; and (iv) for women diagnosed with PT, determine appropriate breast cancer screening schedules. During a 23.7 years time frame, PT was diagnosed in 30 women, reflecting an incidence of 2.53 per 100 000 women screened. Only 22 (73.3%) PT were found by screening. The remaining eight (26.7%) presented as interval tumours. Thirteen PT were benign, eight borderline and nine malignant. Six of eight (75%) malignant PT were symptomatic. A circumscribed mass, mean diameter 34.7 mm, was the dominant finding. Enlargement (14 imaging, seven clinical) was documented in 21 (70%) cases. Diagnostic open biopsy was required in 67.9%. Follow-up of at least 12 months is available in 20 cases. Only two developed recurrence. One woman died of metastatic PT and one PT recurred locally. The extreme rarity of PT in screening contrasts with the prevalence of FAs. The peak incidence of PT in women is 40-50, whereas screening is targeted at women 50-74. Two yearly screening mammography is not designed to detect PT reliably. In particular, malignant PT grows rapidly and becomes symptomatic. Women with benign PT can continue with screening. Women with borderline and malignant PT should resume screening after 5 years of specialist surveillance. © 2015 Royal Australasian College of Surgeons.

    ABSTRACT: Balloon dilatation of the ampulla at endoscopic retrograde cholangiopancreatography (ERCP) is increasingly utilized in the management of large bile duct stones. The aim of this study was to review and compare the outcomes of using endoscopic sphincterotomy with endoscopic balloon dilatation (sphincteroplasty) in a combined approach as a single-stage (immediate) or a two-stage procedure (delayed). A retrospective review of medical records for all patients undergoing ERCP and balloon dilatation for choledocholithiasis between January 2010 and December 2012 was undertaken. Outcomes measured included patient demographics, stone size, degree of dilatation performed, success of stone extraction, number of procedures required for duct clearance and procedure-related complications. One hundred and thirty-six ERCPs were performed with balloon sphincteroplasty. One hundred and four had a previous sphincterotomy with a delayed balloon dilatation and 32 had sphincterotomy with immediate dilatation. The overall clearance rate of the common bile duct for immediate and delayed groups was 93% (28/30) and 93% (81/87), respectively. Bile duct clearance after the first procedure was achieved in 70% (21/30) of patients in the immediate group and 74% (64/87) in the delayed group. There were six complications in the delayed group and four in the immediate group. The most frequently used balloon size was 10 mm for both groups with mean sizes of 10.34 (2.93) and 11.73 (2.87) in the immediate and delayed groups, respectively. Our study suggests that use of a combined approach is safe and effective and may provide benefits over using endoscopic balloon dilatation or endoscopic sphincterotomy alone in the treatment of choledocholithiasis. © 2015 Royal Australasian College of Surgeons.

    ABSTRACT: The role and type of pelvic lymph node dissection for clinically localized prostate cancer is controversial in Australia. Our study aims to determine the incidence of pelvic lymph node involvement and the complication rate of extended lymphadenectomy in a group of West Australian patients who underwent a robotic assisted radical prostatectomy plus extended pelvic lymph node dissection. Forty-nine patients underwent a robotic assisted radical prostatectomy with extended pelvic lymph node dissection between 2008 and 2012 by a single private urological surgeon. The inclusion criteria for the extended lymph node dissection were clinical localized, intermediate and high-risk prostate cancer based on preoperative D'Amico classification. Of the 49 patients, eight patients had positive nodes giving a nodal positivity rate of 16.33%. Six patients had a complication giving a total complication rate of 12.24%. Three of these complications have been attributed to the nodal dissection, thus giving an extended pelvic lymph node dissection complication rate of 6.12%. Rates of nodal involvement in our West Australian cohort are in keeping with those published in the literature. Extended pelvic lymph node dissection can be performed with an acceptable complication rate. Further research is required to investigate the therapeutic role of pelvic lymph node dissection. © 2015 Royal Australasian College of Surgeons.

    ABSTRACT: The aim of this study was to audit the blood transfusion practice throughout the Epworth Healthcare Hospitals for patients undergoing primary total hip replacement (THR). We determined if blood-saving techniques were having an impact on the risk of allogenic blood transfusion and which patients were at risk of receiving allogenic blood transfusion. This study uses a retrospective audit of 787 patients who had undergone primary THR surgery at three Melbourne hospitals: Epworth Richmond, Epworth Eastern and Epworth Freemasons in 2010. Patient demographics, transfusion requirements and blood-conserving techniques were recorded. One hundred and eighty (23%) patients received allogenic blood transfusion and 18 (2.3%) patients received autologous blood transfusion. On multivariate analysis, preoperative anaemia (odds ratio (OR) 4.7, P < 0.0001), female gender (OR 3.1, P < 0.0001) and patient age (OR 1.07 per year of age increase, P < 0.0001) were shown to be significantly associated with higher risk of allogenic blood transfusion. Use of spinal anaesthetic was found to be associated with lower risk of transfusion (OR 0.6, P = 0.0180) compared with general anaesthetic alone. Cell saver, acute normovolaemic haemodilution and re-infusion drain tube usage did not have a significant impact on reducing the risk of allogenic blood transfusion. Identification of patients at risk of blood transfusion, correction of preoperative anaemia and a restrictive transfusion policy are important factors to consider in effective perioperative blood management. © 2015 Royal Australasian College of Surgeons.

    ABSTRACT: After ileocecal resection for Crohn's disease, a temporary faecal diversion is indicated in high-risk patients. The impact of a temporary stoma on post-operative morbidity has been poorly assessed so far. The aim was to analyse post-operative morbidity of temporary faecal diversion after ileocecal resection for Crohn's disease. Patients undergoing temporary faecal diversion combined with ileocecal resection were retrospectively included. Patients presenting with complications were compared with patients with an uneventful post-operative course, to identify any predictive factor for morbidity. Eighty faecal diversions were performed (43 males, 33.5 (18-75) years), including 63 split stoma (79%) and 17 covering loop ileostomies (21%). Fifty-two patients (65%) presented with a perforating disease. Post-operative complications occurred in 15 patients (19%), 15 days after surgery (1-30). The main complications were intra-abdominal abscess (n = 6), functional renal failure (n = 6), fistula (n = 2) and stomal prolapse (n = 2). Two patients required surgery. Previous bowel resections (60% versus 28%, P = 0.01) were significantly associated with post-operative morbidity. Temporary faecal diversion is useful in high-risk patients after ileocecal resection for Crohn's disease. Patients' information about post-operative risks remains an important issue. Risk factors for post-operative morbidity despite faecal diversion are previous bowel resections. © 2015 Royal Australasian College of Surgeons.

    ABSTRACT: Technical advances have improved the detection of small mammographic lesions. In the context of mammographic screening, accurate sampling of these lesions by percutaneous biopsy is crucial in limiting diagnostic surgical biopsies, many of which show benign results. Women undergoing core biopsy between January 1997 and December 2007 for <10-mm lesions are included. Patient demographics, imaging features and final histology were tabulated. Performance indices were evaluated. This audit includes 803 lesions <10 mm. Based on core histology, 345 women (43.0%) were immediately cleared of malignancy and 300 (37.4%) were referred for definitive cancer treatment. A further 157 women (19.6%) required diagnostic surgical biopsy because of indefinite or inadequate core results or radiological-pathological discordance, and one woman (0.1%) needed further imaging in 12 months. The open biopsies were malignant in 46 (29.3%) cases. The positive predictive value of malignant core biopsy was 100%. The negative predictive value for benign core results was 97.7%, and the false-negative rate was 2.6%. The lesion could not be visualized after core biopsy in 5.1% of women and in 4.0% of women with malignant core biopsies excision specimens did not contain residual malignancy. Excessive delays in surgery because of complications of core biopsy were not reported. Even at this small size range, core biopsy evaluation of screen-detected breast lesions is highly effective and accurate. A lesion miss rate of 3.1% and under-representation of lesions on core samples highlight the continued need for multidisciplinary collaboration and selective use of diagnostic surgical biopsy. © 2015 Royal Australasian College of Surgeons.

    ABSTRACT: The reduced availability of human cadavers and their associated high costs, coupled with an increasing requirement for meeting continuing professional development targets, has accentuated the need for alternative training models that meet current ethical standards. The aim of this study is to identify suitable substitutes that are accessible and cost effective for use as training models for meniscal repairs and small joint arthroscopy. Ovine, bovine and porcine stifles were analysed for comparable anatomy to the human knee, arthroscopic access, arthroscopic view and ease of meniscal repair. The bovine stifle joint was found to be too large and offered limited access due to a large anterior fat pad and thick surrounding soft tissue. The ovine and bovine stifles were both easily available and had comparable anatomy to the human knee. Advantages of the porcine stifle include better availability and easier accessibility, comparable anatomy to the human knee and its relatively larger size that made it easier to arthroscope. Porcine stifles are cost effective, accessible, allow for meniscal repair and are suitable for arthroscopic access and view. Our view is that they are an ideal training model for arthroscopic meniscal repair, small joint arthroscopy and anterior cruciate ligament reconstruction. © 2015 Royal Australasian College of Surgeons.
