Summary
Dr Eric Gan Keng Seng v Singapore Medical Council [2010] SGHC 325 concerned an appeal by a consultant surgeon against a disciplinary finding that he committed professional misconduct under s 45(1)(d) of the Medical Registration Act (Cap 174). The disciplinary charge that mattered on appeal related not to the performance of a procedure per se (the DC acquitted him on that aspect), but to the quality and timeliness of his post-operative management of a patient following an ERCP procedure complicated by a failed pre-cut sphincterotomy attempt.
The High Court (Chao Hick Tin JA, Andrew Phang Boon Leong JA and Steven Chong J) upheld the DC’s finding of guilt on the second charge. The court accepted that the patient’s clinical deterioration after the procedure required prompt and appropriate investigation to rule out a known serious complication—duodenal perforation—and that Dr Gan’s management fell below the standard expected of a registered medical practitioner. The court also affirmed the sanctions imposed, including a six-month suspension, censure, a written undertaking, and an order that Dr Gan pay 70% of the costs.
What Were the Facts of This Case?
Dr Eric Gan was a medical practitioner of about 19 years’ standing and served as a Consultant Surgeon at Mount Elizabeth Hospital, and as a Visiting Consultant Surgeon at the National University Hospital and Alexandra Hospital. The patient, Mr Toh Hock Ken (“the Patient”), first came under Dr Gan’s care when he was admitted to Alexandra Hospital (“AH”) on 13 November 2005 after an acute episode of 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 Patient’s common bile duct and advised an endoscopic retrograde cholangiopancreatogram (“ERCP”). The Patient agreed after being told that ERCP was a very common procedure with hardly any risk. On 6 December 2005, Dr Gan performed the ERCP at AH at about 3.00 pm. Initial cannulation attempts were unsuccessful, and Dr Gan attempted a further procedure described as the “Pre-cut Technique”. Despite this, he still failed to gain access to the bile duct and halted the Pre-cut Technique to consider an alternative plan.
Following the failed ERCP and Pre-cut Technique, the Patient’s condition deteriorated. The DC’s tabulation of events showed that the Patient was kept nil-by-mouth post procedure, which was not Dr Gan’s usual practice. By around 1710 hours on 6 December 2005, the Patient’s abdomen felt distended and discomfort and tenderness were noted. By 1745 hours, there were episodes of bilious vomiting. At 1800 hours, the Patient was unwell with epigastric pain radiating to the back, and voluntary guarding was detected. The on-call registrar, Dr Eugene Lim, assessed the situation as possible post-ERCP complications, and Dr Gan instructed blood tests and an erect chest X-ray.
On the evening of 6 December 2005, Dr Gan left AH for the day. Around 9.50 pm, Dr Lim conveyed test results to Dr Gan by telephone. The Patient’s serum amylase was elevated to 593U/L (more than five times normal), and the erect chest X-ray did not show subcutaneous emphysema, pneumomediastinum, or gas under the diaphragm. Based on a working diagnosis of acute pancreatitis, Dr Gan instructed treatment for pancreatitis and directed that the Patient be kept fasted, started on IV drip, given a nasogastric tube, administered pethidine, and placed under close observation with periodic abdominal review.
On 7 December 2005, Dr Gan visited the Patient at about 8.50 am. Although the Patient’s vital signs remained normal and there was no fever, he still complained of abdominal pain and had a slightly distended abdomen with tenderness in the right hypochondrium. Dr Gan detected a right pleural effusion and ordered a second chest X-ray, which confirmed the effusion. Later that day, at about 5.00 pm, Dr Gan observed that the abdominal signs had changed: tenderness had spread down the right flank and there was guarding. He ordered a CT scan of the abdomen and pelvis to ascertain whether there was a perforation of the duodenum. The CT scan revealed a retroduodenal perforation, and Dr Gan performed an emergency exploratory laparotomy in the early hours of 8 December 2005. The surgery revealed large amounts of bile-stained fluid in the peritoneal cavity and fluid in retroperitoneal spaces. Despite efforts, the Patient died on 22 January 2006 from septicaemia due to intra-abdominal sepsis.
After the Patient’s wife lodged a complaint on 12 April 2007, the Complaints Committee initially issued only a letter of advice. Dissatisfied, the complainant wrote to the Minister of Health, who invoked powers under the Act to convene a disciplinary inquiry. Two charges were brought. The first charge concerned whether Dr Gan performed the Pre-cut Technique when he knew or ought to have known it was beyond his competence; the DC acquitted him on that charge. The second charge—central to the appeal—alleged wilful neglect of duties and gross mismanagement of post-operative treatment between 6 and 8 December 2005, particularly focusing on the failure to carry out appropriate clinical investigation (a CT scan) within reasonable time to rule out duodenal perforation, a known risk of ERCP and the Pre-cut Technique.
What Were the Key Legal Issues?
The appeal raised two interrelated issues. First, the court had to determine whether the DC was correct to find that Dr Gan’s conduct amounted to professional misconduct under s 45(1)(d) of the Medical Registration Act. This required assessing whether his post-operative management—especially the timing and adequacy of investigations—constituted wilful neglect and gross mismanagement in the circumstances.
Second, the court had to consider the appropriate standard of review for disciplinary findings. In professional misconduct appeals, the High Court does not simply substitute its own view for that of the DC; it must evaluate whether the DC’s findings were supported by the evidence and whether the DC applied the correct legal approach to professional misconduct. The court also had to address whether the sanctions were proportionate given the nature of the misconduct and the resulting harm.
How Did the Court Analyse the Issues?
The High Court began by framing the appeal as an attack on the DC’s finding on the second charge. The DC had acquitted Dr Gan on the first charge relating to competence and the Pre-cut Technique itself. Accordingly, the court’s focus was on post-operative care from 6 December 2005 to 8 December 2005, and in particular whether Dr Gan’s clinical decisions and management met the standard expected of a consultant surgeon.
A central feature of the DC’s reasoning, and therefore of the High Court’s analysis, was the known risk profile of ERCP and the Pre-cut Technique. Duodenal perforation was treated as a known complication. The court considered that, once the Patient developed symptoms consistent with possible perforation—such as bilious vomiting, epigastric tenderness, guarding, and later spreading tenderness—Dr Gan had a duty to investigate promptly to rule out perforation. The charge’s particulars emphasised that Dr Gan failed to carry out an appropriate clinical investigation by CT scan within reasonable time to ascertain whether there was duodenal perforation.
The court also examined the clinical timeline and the reasoning behind the working diagnosis. The Patient’s elevated amylase and the initial chest X-ray findings were consistent with pancreatitis, and Dr Gan instituted pancreatitis treatment. However, the court’s analysis recognised that clinical deterioration and evolving signs can require reconsideration of the differential diagnosis. The presence of a right pleural effusion and the later development of guarding and spreading tenderness were treated as significant clinical indicators that should have triggered earlier imaging to exclude perforation.
In assessing whether Dr Gan’s conduct amounted to wilful neglect and gross mismanagement, the court applied the legal concept that professional misconduct involves conduct that falls seriously short of the standard expected of a medical practitioner. The High Court’s approach reflected that the disciplinary regime is protective and disciplinary in nature: it is concerned with maintaining public confidence in the medical profession and ensuring that practitioners comply with professional standards. Where a known serious complication is not investigated within a reasonable time despite clinical signs, the court considered that this can amount to gross mismanagement even if the practitioner initially made a plausible diagnosis.
The court further considered the evidence of expert medical opinion. While the extract provided does not reproduce the full expert discussion, the metadata indicates that Dr Cheng (gastroenterology and internal medicine) was the expert witness for the SMC before the DC, and that Dr Gan called Prof Ho as his expert. In disciplinary cases, expert evidence typically assists the DC in determining what a competent practitioner would have done in the same circumstances, including what investigations should be ordered, when they should be ordered, and how clinical findings should be interpreted. The High Court, in upholding the DC, effectively accepted that the DC’s evaluation of the evidence supported the conclusion that Dr Gan’s investigation and management were not merely imperfect but fell into the category of professional misconduct.
Finally, the court addressed the sanctions. The DC imposed a six-month suspension, censure, a written undertaking, and a costs order of 70%. The High Court’s reasoning on sanctions would have reflected the seriousness of the misconduct, the patient’s death, and the need for deterrence and protection of the public. The fact that Dr Gan was acquitted on the competence-related first charge did not mitigate the second charge, because the second charge concerned post-operative management and the timeliness of ruling out a known life-threatening complication.
What Was the Outcome?
The High Court dismissed Dr Gan’s appeal and upheld the Disciplinary Committee’s decision that he was guilty of professional misconduct under s 45(1)(d) of the Medical Registration Act. The court affirmed the DC’s findings that Dr Gan wilfully neglected his duties and grossly mismanaged the post-operative treatment of the Patient, particularly in relation to the failure to carry out appropriate investigation within reasonable time to rule out duodenal perforation.
The court also upheld the sanctions imposed by the DC: suspension from practice for six months, censure, a written undertaking to the SMC not to engage in the complained-of conduct or similar conduct, and an order that Dr Gan pay 70% of the costs and expenses of the proceedings, including the solicitor’s costs to the SMC and the Legal Assessor’s costs.
Why Does This Case Matter?
Dr Eric Gan Keng Seng v Singapore Medical Council is significant for practitioners because it illustrates how disciplinary liability can arise from post-operative decision-making, even where the initial diagnosis may appear clinically defensible. The case underscores that a practitioner’s duty is not limited to making an initial working diagnosis; it includes reassessing the patient as new signs emerge and ensuring that investigations are ordered promptly to exclude serious complications.
For medical professionals, the case reinforces the practical expectation that known risks associated with procedures like ERCP must be actively managed through timely investigation when symptoms suggest those risks. For lawyers and law students, it provides a clear example of how professional misconduct under s 45(1)(d) can be established through a combination of (i) clinical facts and timelines, (ii) expert evidence about standards of care, and (iii) the legal characterisation of conduct as “wilful neglect” and “gross mismanagement”.
From a disciplinary procedure perspective, the case also demonstrates the High Court’s willingness to uphold DC findings where the evidence supports the conclusion that the practitioner’s conduct fell seriously below professional standards. It therefore serves as a useful reference point for future appeals concerning the adequacy and timing of investigations, the interpretation of evolving clinical signs, and the proportionality of sanctions in professional misconduct cases.
