Summary
This High Court decision concerns an appeal by Dr Eric Gan Keng Seng (“Dr Gan”) against the Singapore Medical Council’s disciplinary findings that he committed professional misconduct under s 45(1)(d) of the Medical Registration Act (Cap 174, 2004 Rev Ed) (“the Act”). The disciplinary charge that resulted in conviction related not to the performance of an ERCP-related technique itself (for which Dr Gan was acquitted), but to the manner in which he managed and investigated the patient’s post-operative condition over a critical period from 6 December 2005 to 8 December 2005.
The patient, Mr Toh Hock Ken (“the Patient”), underwent an ERCP procedure at Alexandra Hospital in the afternoon of 6 December 2005. After unsuccessful cannulation attempts and an attempted pre-cut technique, the Patient developed symptoms consistent with a known complication risk of ERCP: perforation of the duodenum. The DC found that Dr Gan wilfully neglected his duties and grossly mismanaged the post-operative treatment by failing to carry out appropriate clinical investigations—particularly timely CT imaging—to rule out perforation, and by managing the patient in a way that delayed recognition and treatment of the eventual intra-abdominal perforation and sepsis. The High Court upheld the DC’s finding and sanctions.
Practically, the case underscores that disciplinary liability in Singapore’s medical regulatory framework can attach to clinical decision-making and escalation/investigation practices after a procedure, even where the practitioner is acquitted on the initial technical performance charge. It also illustrates the evidential and standard-of-review approach the High Court applies when reviewing disciplinary committee decisions.
What Were the Facts of This Case?
Dr Gan was a consultant surgeon with approximately 19 years of standing, practising at Mount Elizabeth Hospital and serving as a visiting consultant surgeon at National University Hospital and Alexandra Hospital. The Patient first came under Dr Gan’s care when admitted to Alexandra Hospital on 13 November 2005 for severe, colicky upper abdominal pain. After treatment, the Patient was discharged on 15 November 2005. At a follow-up outpatient appointment on 29 November 2005, Dr Gan identified a possibility of stones in the common bile duct and advised an ERCP. The Patient agreed after being told that ERCP was a common procedure with minimal risk.
On 6 December 2005 at about 3.00 pm, Dr Gan performed an ERCP at Alexandra Hospital. Initial cannulation attempts were unsuccessful. Dr Gan then attempted a further procedure described as the “Pre-cut Technique” on the Patient. Despite this, Dr Gan still failed to gain access to the bile duct and halted the Pre-cut Technique to consider an alternative plan. The DC later treated the failed ERCP and attempted pre-cut technique as clinically significant because perforation of the duodenum is a known risk of ERCP and of the pre-cut technique.
After the procedure, the Patient was kept nil-by-mouth post-procedure, which the DC noted was not Dr Gan’s usual practice in previous cases. Over the evening of 6 December 2005, the Patient developed signs and symptoms that raised concern for complications: abdominal distension, discomfort and tenderness, bilious vomiting, epigastric pain radiating to the back, and voluntary guarding. The on-call registrar, Dr Eugene Lim, assessed the situation as possible post-ERCP complications and Dr Gan instructed investigations including blood tests and an erect chest X-ray. The Patient’s serum amylase was elevated to more than five times normal, and the chest X-ray did not show certain radiological signs such as subcutaneous emphysema or pneumomediastinum.
On 7 December 2005, the Patient remained symptomatic, including abdominal pain and a slightly distended abdomen with tenderness. Dr Gan visited the Patient at about 8.50 am and ordered a second chest X-ray, which confirmed a right pleural effusion. Later that day, Dr Gan observed changes in the abdominal signs, including spread of tenderness and guarding, and ordered a CT scan of the abdomen and pelvis to ascertain whether there was duodenal perforation. The CT scan performed at about 10.00 pm revealed a retroduodenal perforation. Dr Gan then performed an emergency exploratory laparotomy in the early hours of 8 December 2005. The surgery revealed bile-stained fluid and haemoserous fluid in the peritoneal cavity and retroperitoneal spaces. Despite subsequent efforts, the Patient died on 22 January 2006 from septicaemia due to intra-abdominal sepsis.
What Were the Key Legal Issues?
The central legal issue was whether the DC was correct to find that Dr Gan’s conduct amounted to professional misconduct under s 45(1)(d) of the Act. That provision criminalises or regulates professional misconduct by registered medical practitioners, and the DC’s finding turned on whether Dr Gan’s post-operative management amounted to “wilful neglect of duties” and “gross mismanagement” in relation to the Patient’s treatment.
In practical terms, the dispute focused on clinical investigation and escalation: whether Dr Gan failed to carry out appropriate investigations within a reasonable time to rule out duodenal perforation, given the Patient’s post-procedure symptoms and the known complication risks of ERCP and the attempted pre-cut technique. The DC’s conviction on the second charge required it to be satisfied that the omissions and management decisions were not merely errors of judgment but rose to the level of wilful neglect and gross mismanagement.
On appeal, a further legal issue concerned the High Court’s approach to reviewing disciplinary decisions. The court had to determine the appropriate standard of review—particularly whether it should defer to the DC’s findings of fact and evaluation of expert evidence, or whether it should intervene because of legal error, misapprehension of evidence, or a conclusion that was plainly wrong.
How Did the Court Analyse the Issues?
The High Court, delivering judgment through Chao Hick Tin JA (with Andrew Phang Boon Leong JA and Steven Chong J concurring), approached the appeal by first identifying the DC’s factual findings and the reasoning underpinning the conviction. The court noted that the DC acquitted Dr Gan on the first charge concerning the performance of the pre-cut technique beyond the scope of competence. That acquittal narrowed the focus of the appeal to the second charge: the manner in which Dr Gan managed the Patient after the procedure and whether he failed to investigate and respond appropriately to signs suggesting perforation.
In analysing the mismanagement charge, the court emphasised the clinical context known to Dr Gan at the time. The DC had found that perforation of the duodenum was a known risk of ERCP and the pre-cut technique. Importantly, Dr Gan was aware that the cannulation attempts had failed and that the pre-cut technique had been attempted. After the procedure, the Patient developed symptoms—bilious vomiting, epigastric tenderness, guarding, and elevated amylase—that were consistent with post-ERCP complications. The court treated these as objective indicators that should have triggered timely and appropriate investigation to rule out perforation.
The court’s reasoning also addressed the timing of CT imaging. While Dr Gan ordered blood tests and an erect chest X-ray on the evening of 6 December 2005, the DC found that the appropriate clinical investigation by CT scan of the abdomen and pelvis to ascertain perforation was not carried out within a reasonable time. The CT scan was arranged on the evening of 7 December 2005 and revealed free air and fluid. The High Court accepted that the delay was material because perforation, once present, can progress rapidly to intra-abdominal sepsis. The court therefore considered that the failure to rule out perforation earlier constituted wilful neglect and gross mismanagement rather than an acceptable clinical variation.
Another aspect of the court’s analysis concerned the management steps taken in the interim. Based on a working diagnosis of acute pancreatitis, Dr Gan instituted pancreatitis treatment and instructed measures such as fasting, IV drip, nasogastric tube insertion, and pethidine, along with close observation. The High Court did not treat these steps as inherently improper; rather, it assessed whether, in light of the Patient’s evolving symptoms and the known risks, Dr Gan’s approach sufficiently addressed the need to exclude a perforation diagnosis promptly. The court’s conclusion was that the clinical pathway chosen by Dr Gan did not adequately meet the standard expected of a consultant surgeon managing a post-ERCP complication where perforation was a realistic possibility.
Finally, the High Court addressed the evidential basis for the DC’s conclusion, including the expert evidence. The DC had heard expert testimony from Dr Cheng (who later became the sole expert witness for the SMC before the DC) and from Dr Gan’s expert, Prof Ho. The High Court’s analysis reflected the principle that disciplinary bodies are entitled to evaluate expert evidence and draw conclusions about professional standards. Unless the appellant could show legal error or that the DC’s conclusion was not reasonably open on the evidence, the High Court would not readily disturb the DC’s findings.
What Was the Outcome?
The High Court dismissed Dr Gan’s appeal and upheld the DC’s decision finding him guilty of professional misconduct under s 45(1)(d) of the Act. The conviction therefore remained in place, including the DC’s characterisation of Dr Gan’s conduct as wilful neglect of duties and gross mismanagement of the Patient’s post-operative treatment.
Accordingly, the sanctions imposed by the DC were maintained: suspension from practice for six months, censure, a written undertaking to the SMC not to engage in the conduct complained of or similar conduct, and an order that Dr Gan pay 70% of the costs and expenses of the proceedings, including the solicitor’s costs for the SMC and the costs of the Legal Assessor. The practical effect is that Dr Gan faced a period of suspension and ongoing regulatory obligations, while also bearing a substantial portion of the disciplinary costs.
Why Does This Case Matter?
This case is significant for practitioners because it clarifies how Singapore’s medical disciplinary framework evaluates post-procedure clinical management. Even where a practitioner is acquitted on a technical performance charge, disciplinary liability may still arise from failures in investigation, escalation, and management after the procedure. The decision therefore reinforces that professional responsibility extends beyond the operating theatre and includes the duty to respond appropriately to complications as they develop.
From a doctrinal perspective, the case illustrates the application of s 45(1)(d) of the Act to conduct characterised as “wilful neglect” and “gross mismanagement”. While the precise threshold between an error of judgment and professional misconduct can be fact-sensitive, the court’s reasoning indicates that where known risks exist and objective symptoms emerge, a failure to investigate within a reasonable time may be treated as more than mere negligence. The case thus provides guidance on how disciplinary bodies may interpret “gross” mismanagement in the context of diagnostic delay.
For law students and legal practitioners advising medical professionals, the decision is also useful for understanding the appellate posture in disciplinary matters. The High Court’s approach reflects deference to the DC’s evaluation of evidence and professional standards, absent demonstrable legal error. Accordingly, appeals in this domain often turn on whether the DC misdirected itself on the law, misunderstood key evidence, or reached a conclusion not reasonably open on the record.
