INTRODUCTIONMale breast cancer is a rare disease entity, with little data from the Southeast Asian perspective. Hence, this study aims to review the data from our local experience in order to better delineate the disease characteristics in our population.
MATERIALS AND METHODSMale patients with histologically proven breast cancer were identified from a prospectively collected database. The clinical, histopathological and survival data were reviewed retrospectively and analysed.
RESULTSTwenty-one patients were identified. The median age at diagnosis was 68 years. Eighteen patients underwent simple mastectomy with curative intent, with the remaining patients having metastatic disease at presentation. Almost half of the patients presented with stage III or IV disease. At the time of analysis, median overall survival was 50 months and median disease-free survival was 47.5 months. None of the patients had any documented family history or risk factors for male breast cancer.
CONCLUSIONThe disease appears to be a sporadic and rare occurrence in the local male population. A high index of suspicion should be maintained in males presented with a unilateral breast lump so that appropriate treatment can be instituted.

INTRODUCTIONThe SingHealth Residency General Surgery Programme replaced the basic and advanced specialist training (AST) system in Singapore in 2010. The relative merits of both systems continue to be debated, especially the operational readiness of graduating residents. We set out to compare the operative and endoscopic volumes of graduates from the AST system with those from the first graduating batch of the residency programme during their registrar (or equivalent) years, as a reflection of procedural experience gained during traineeship.
METHODSOperative and endoscopic records of four graduating residents and seven AST system trainees were extracted from the cluster-wide Operating Theatre Management system and compared. Surgeries were analysed as registrar-level operations and their corresponding subspecialties.
RESULTSRegistrars and senior residents performed a mean of 1,182 and 533 general surgical operations, respectively. Median percentage loss in operative volume was 50.6% (range 9.6%-75.5%). The mean number of total gastroscopies and colonoscopies performed by registrars (total gastroscopy, n = 819; total colonoscopy, n = 743) and senior residents (total gastroscopy, n = 376; total colonoscopy, n = 412) indicated a mean loss of 54.1% and 44.6%, respectively, in gastroscopic and colonoscopic experience.
CONCLUSIONThe residency programme aims to provide robust and complete surgical training. The operational readiness of its graduates is often scrutinised against that from the old system. Although a significant difference in surgical and endoscopic volumes was observed between the two trainee groups, this is only one marker of surgical experience and technical competence.

INTRODUCTIONWe aimed to analyse the changing trends, safety and outcomes associated with the adoption of laparoscopic liver resection (LLR) at a single centre.
METHODSA retrospective review of patients who underwent LLR from 2006 to 2014 at our institution was performed. To explore the evolution of LLR, the study was divided into three equal consecutive time periods (Period 1: 2006-2008, Period 2: 2009-2011, and Period 3: 2012-2014).
RESULTSAmong 195 patients who underwent LLR, 24 (12.3%) required open conversions, 68 (34.9%) had resection of tumours in the difficult posterosuperior segments and 12 (6.2%) underwent major (≥ 3 segments) hepatectomies. Median operation time was 210 (range 40-620) minutes and median postoperative stay was 4 (range 1-26) days. Major postoperative morbidity (> Grade II) occurred in 11 (5.6%) patients and 90-day/in-hospital mortality was 1 (0.5%). During the study, the number of LLRs performed showed an increasing trend (Period 1: n = 22; Period 2: n = 19; Period 3: n = 154). Other statistically significant trends were: (a) increase in malignant neoplasms resected; (b) increase in resections of difficult posterosuperior segments; (c) longer median operation time; and (d) decrease in open conversion rates.
CONCLUSIONOver the study period, the number of LLRs increased rapidly. LLR was increasingly performed for malignant neoplasms and lesions located in the difficult posterosuperior segments, resulting in longer operation times. However, open conversion rates decreased, and there was no change in postoperative morbidity and other perioperative outcomes.
