Summary
This High Court appeal concerned professional misconduct proceedings brought by the Singapore Medical Council (“SMC”) against Dr Eric Gan Keng Seng, a consultant surgeon, arising from his management of a patient following an ERCP procedure at Alexandra Hospital in December 2005. The Disciplinary Committee (“DC”) acquitted Dr Gan on a first charge relating to the performance of a “Pre-cut Technique” beyond the scope of his competence, but convicted him on a second charge alleging wilful neglect of duties and gross mismanagement of the patient’s post-operative treatment between 6 and 8 December 2005. The DC imposed a six-month suspension, censure, a written undertaking, and an order that Dr Gan pay 70% of the costs and expenses of the proceedings.
On appeal, the High Court (Chao Hick Tin JA, Andrew Phang Boon Leong JA and Steven Chong J) upheld the DC’s finding of professional misconduct. The central theme was not whether the patient’s death was causally attributable in a strict tort sense, but whether Dr Gan’s clinical management fell below the standard expected of a registered medical practitioner in the circumstances—particularly the adequacy and timeliness of investigations to rule out a known serious complication (duodenal perforation) after a failed ERCP attempt and subsequent symptoms consistent with that complication.
What Were the Facts of This Case?
The patient, Mr Toh Hock Ken (“the Patient”), was admitted to Alexandra Hospital (“AH”) in November 2005 after an acute episode of severe, colicky upper abdominal pain. After initial 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 reassured by Dr Gan that ERCP was a common procedure with minimal risk.
On 6 December 2005, Dr Gan performed the ERCP at AH at about 3.00 pm. During the procedure, initial cannulation attempts were unsuccessful. Dr Gan then attempted a further procedure known as the “Pre-cut Technique”. Despite this, Dr Gan still failed to gain access to the bile duct and had to halt the Pre-cut Technique to consider an alternative treatment plan. The DC later treated the failed ERCP attempt and the Pre-cut Technique as clinically significant context for what should have followed afterwards in terms of post-operative monitoring and investigation.
After the procedure, the Patient was kept nil-by-mouth, which the DC noted was not Dr Gan’s usual practice based on previous cases. Over the evening of 6 December 2005, the Patient developed symptoms and signs including abdominal distension, discomfort and tenderness, bilious vomiting, and epigastric pain radiating to the back. 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 blood tests showed a markedly elevated serum amylase (more than five times normal), and the chest X-ray did not show certain radiological signs such as subcutaneous emphysema, pneumomediastinum or gas under the diaphragm. Dr Gan, working on a diagnosis of acute pancreatitis, instituted pancreatitis treatment and ordered further management steps including fasting, IV drip, nasogastric tube insertion and pethidine, with close observation.
On 7 December 2005, Dr Gan visited the Patient. Although the Patient’s vital signs remained normal and there was no fever, the Patient continued to complain of abdominal pain and had a slightly distended abdomen with tenderness. Dr Gan also noted a right pleural effusion and ordered a second chest X-ray, confirming the effusion. Later that day, Dr Gan observed that the Patient’s abdominal signs had changed: tenderness had spread down the right flank and guarding was present. Dr Gan then ordered a CT scan of the abdomen and pelvis to ascertain whether there was duodenal perforation. The CT scan revealed a retroduodenal perforation. Dr Gan performed an emergency exploratory laparotomy in the early hours of 8 December 2005, which found bile-stained fluid and haemoserous fluid in the peritoneal cavity and similar collections in 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 primary legal issue was whether Dr Gan’s conduct amounted to “professional misconduct” under s 45(1)(d) of the Medical Registration Act. In disciplinary proceedings, the question is not merely whether there was a deviation from best practice, but whether the deviation is of such a nature and degree that it crosses the threshold into professional misconduct. Here, the DC’s conviction focused on wilful neglect of duties and gross mismanagement of post-operative treatment, rather than the earlier acquitted charge relating to the Pre-cut Technique itself.
A second key issue concerned the adequacy of Dr Gan’s investigative and management response to a known serious risk. Duodenal perforation is a known complication of ERCP and of the Pre-cut Technique. The legal question was whether, given the Patient’s clinical course after the procedure—particularly the onset of bilious vomiting, abdominal tenderness and later guarding—Dr Gan failed to carry out appropriate clinical investigations within a reasonable time to rule out perforation. This required the court to consider how medical judgment is assessed in disciplinary contexts: whether the court should substitute its own clinical view, or whether it should evaluate whether the practitioner’s actions were defensible and consistent with the standard expected of a competent practitioner in those circumstances.
Finally, the appeal raised issues about the role of expert evidence and the proper approach to reviewing the DC’s findings. The High Court had to determine whether the DC’s conclusions were supported by the evidence and whether the DC had applied the correct legal test for professional misconduct.
How Did the Court Analyse the Issues?
The High Court approached the appeal by first identifying the DC’s findings and the factual matrix underpinning them. The court emphasised that the DC acquitted Dr Gan on the first charge, meaning the appeal concerned only the second charge relating to post-operative care. The analysis therefore centred on what Dr Gan did after the failed ERCP attempt and Pre-cut Technique, and whether his subsequent management—especially the decision-making around investigations—was appropriate in light of the Patient’s symptoms and the known risk of perforation.
In analysing the mismanagement charge, the court considered the SMC’s case that perforation was a known risk and that it was imperative to rule it out, particularly given Dr Gan’s awareness of the failed Pre-cut Technique and the clinical deterioration that followed. The court treated the Patient’s evolving symptoms as clinically meaningful indicators that should have triggered more prompt and targeted investigation. Although the initial blood tests supported pancreatitis (elevated amylase), the court noted that pancreatitis and perforation are not mutually exclusive, and that a working diagnosis should not lead to a failure to consider and investigate other serious complications.
The court also examined the timing of the CT scan. The CT scan was arranged on the evening of 7 December 2005 and revealed a retroduodenal perforation. The DC had found that Dr Gan failed to carry out appropriate clinical investigation by way of CT scan within reasonable time despite the Patient’s condition and medical history. The High Court’s reasoning reflected the disciplinary standard: a practitioner is expected to take reasonable steps to exclude serious complications when the clinical picture warrants it. The court did not treat the absence of certain radiological signs on the erect chest X-ray as dispositive, because the later CT scan demonstrated that perforation was present despite earlier imaging not showing specific signs.
In considering whether Dr Gan’s conduct was “wilful neglect” and “gross mismanagement”, the court applied principles that distinguish ordinary error from professional misconduct. Professional misconduct in this context involves a sufficiently serious departure from the standard of care expected of a registered medical practitioner. The court’s analysis therefore focused on whether Dr Gan’s decisions reflected a failure to exercise the level of diligence and competence required, rather than a mere difference of opinion. The court also took into account the DC’s assessment of expert evidence, including the testimony of specialists called by both parties, and the DC’s evaluation of what a competent practitioner would have done in the same circumstances.
Although the judgment extract provided is truncated, the High Court’s overall approach in such cases is consistent: it reviews whether the DC correctly applied the legal test and whether its factual findings were supported by evidence. Where the DC’s conclusions depend on clinical judgment, the court does not simply re-weigh medical evidence as if it were a medical appeal. Instead, it examines whether the DC’s findings demonstrate a legally sustainable basis for concluding that the practitioner’s conduct crossed the threshold into professional misconduct.
What Was the Outcome?
The High Court dismissed Dr Gan’s appeal and upheld the DC’s decision that he was guilty of professional misconduct under s 45(1)(d) of the Medical Registration Act. The conviction therefore stood, including the DC’s characterisation of Dr Gan’s post-operative management as involving wilful neglect of duties and gross mismanagement.
As a result, the sanctions imposed by the DC remained in effect: 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 and incidental to the proceedings, including solicitor’s costs to the SMC and the Legal Assessor’s costs.
Why Does This Case Matter?
This case is significant for practitioners because it illustrates how disciplinary liability can arise from post-operative decision-making, even where the practitioner is acquitted on an earlier charge relating to the procedure itself. The court’s endorsement of the DC’s findings underscores that professional misconduct may be found where a practitioner fails to respond appropriately to known risks and evolving clinical signs, particularly where serious complications must be actively ruled out through timely investigation.
For medical professionals and their counsel, the case highlights the importance of documenting and justifying clinical reasoning, especially when a working diagnosis is formed. Elevated amylase and a presumptive diagnosis of pancreatitis may not be sufficient to exclude other dangerous outcomes such as perforation. Where symptoms and signs suggest deterioration or complications, disciplinary authorities may expect escalation to definitive imaging (such as CT scanning) within a reasonable time.
From a legal research perspective, the case also demonstrates the High Court’s role in reviewing DC decisions in professional misconduct appeals. The court’s analysis reflects a careful balance: it respects the DC’s fact-finding and the evidential role of medical experts, while ensuring that the correct legal threshold for professional misconduct is applied. Practitioners should therefore treat this decision as a guide to how Singapore courts evaluate the seriousness of clinical departures and the adequacy of investigative steps in disciplinary contexts.
