Again, I fully support this organization. In no way am I trying to discourage members or scare them.
[email protected] There are excellent surgeons out there, please choose wisely.

I just believe since the CPSO conceals the truth, prospective patients of Dr. Klein should be able to access information about him. Yes, many have found him to be great. But I would disagree. I think the major problem is lack of attention during post surgery and he does have a somewhat negligent habit of not providing antibiotics should an infection develop. Quote from Dr. Klein when a nurse asked about prescribing antibiotics for an abdominal incision infection oozing puralent discharge and all staples removed. "The Body Will Heal Itself". Nope, my daughter died. Terra Dawn Kilby

RE: Ms. Terra Dawn Kilbv - Your File #77429

"The independent assessor is correct that Ms. Kilby did not receive preoperative antibiotics. I agree with the independent assessor's opinion in response to your subsequent letter that preoperative antibiotics would not have been a contributing factor to the anastomotic leak. Antibiotics are used to prevent or treat an infection. They have no preventative or beneficial effect for an anastomotic leak.

Furthermore, it is not my practice to prescribe antibiotics for a planned laparoscopic surgery with possibility of conversion to an open procedure.

As I have explained in my initial response, Ms. Kilby did develop a superficial wound infection postoperatively that was treated appropriately. I do not feel that the wound infection 'was in any way related to the outcome of this case. L KLEIN


Oh, my God!!!! Dr. Klein has not learned a thing from Terra's death and is obviously going to continue as he did!
This is detrimental to the safety of patients that are under his care!!!!!!
CPSO statement:
"The routine use of antibiotics prior to bowel surgery is an important aspect of care that was neglected by Dr. Klein in this case. The Committee would suggest that Dr. Klein consider the routine use of antibiotics in such circumstances. Having said that, we do not consider this oversight to have contributed to the unfortunate outcome in this case."

AWKILBY’s Response: Neglected equals Negligence

Notice how the College brings into the discussion my daughter's death from these example below: reason to deflect away from the standards of care to the Terra's death

View the following to see how Laz Klein is being protected by the Hospital, the Chief Coroner's Office, the College of Physicians and Surgeons and the Health Professions Appeal and Reveiw Board;

The Chief Coroner's Office without public knowledge temporarily shut down his department in 2010 due to 5 or 6 deaths. It is difficult to ascertain the total of deaths associated with Dr. Klein. I tried to access only the number of deaths of patients under his care, no names, just the number. I used the Freedom of Information. What I got back and paid for was 50 photocopied pages on bariatric surgery. My daughter did not have this. The other 20 pages were blacked out with many white sections. From looking at some pages that had the same protection of privacy rules, I came to the conclusion that there are three or four. If any of the institutions had truly investigated my daughter's death in 2006, those deaths that followed and are probably continue may very well have been averted. 27 year old Crystal Rose did have bariatric surgery and she died in hospital in December of 2012. How many are there, no one knows? Well the CPSO, Dr. Klein, Humber River Hospital, and the Chief Coroner's Office does but they are not telling.

Here is why:

"Defamation is comprised of two subcategories between libel (libel refers to written defamatory statements)and slander(broadcasting of spoken defamatory words)

Proving a Claim in Libel and/or Slander
"the statement must be false!"

Defences to Actions in Libel and Slander

"The first defence is the defence of truth. The defence can be made that the statement was truthful and therefore there was nothing false about the statement, meaning therefore, that the statement was not defamatory."

"The second defence to an allegation of libelous statement is that the statements made were made as a fair comment. The defence of fair comment would be considered by the Court in situations where, by looking at the statement made, the facts and the situation, a conclusion can be made that the statements made were in actuality a fair commentary on the situation at hand and that the comments were fair and were not malicious."

"The defence of qualified privilege arises normally in situations where the individual publishing these statements will escape any liability if it can be proven that the public good could be furthered in open debate.

Health Professions Appeal and Review Board's Second Decision re: Kilby vs Klein

Excerpts From Their Decision:

The second point that remains is of the greatest concern to the Board. That is so because the Record includes conflicting information concerning the standard of care concerning the use of preoperative antibiotics.

The routine use of antibiotics prior to bowel surgery is an important aspect of care that was neglected by [the Respondent] in this case. The Committee would suggest that [the Respondent] consider the routine use of antibiotics in such circumstances. Having said that, we do not consider this oversight to have contributed to the unfortunate outcome in this case.

This passage appears to the Board to be contradictory. Although the Committee states that the "routine use" of antibiotics prior to surgery is an "important aspect of care" that was "neglected" by the Respondent, it does no more than "suggest" that the Respondent "consider the routine use" of preoperative antibiotics for future surgery. The Committee goes on to describe the Respondent's decision not to provide antibiotics prior to the patient's surgery as an "oversight", which suggests a failure of pre-operative care, regardless of whether the failure contributed to the outcome in the patient's case.

The second question related to whether perioperative antibiotics should have been prescribed. [The IOP] stated that he found no evidence in the record that any antibiotics had been prescribed perioperatively. He staled that it is the standard of practice with bowel surgery to administer antibiotics, either orally or intravenously, approximately 2 hours prior to surgery so that the drugs are circulating before the incision is made. While it makes intuitive sense to administer antibiotics postoperatively, [the IOP] indicated that studies show it is the preoperative dosage that is most important, while postoperative dosing has been found to be "icing on the cake", [emphasis added]

According to this information, the IOP advised the Committee that the standard of practice required the administration of preoperative antibiotics. This appears inconsistent with the statement he made in his written opinion that the patient's "preoperative care, operative care and post operative care seemed appropriate". The matter is further confused, because in answer to the question: "Could this omission [of preoperative antibiotics] be a contributing factor to the defect in the anastomosis seen at autopsy?", the IOP answered "No".

The Board is left in some doubt as to the nature of the IOP's opinion and the Committee's decision concerning the Respondent's decision not to provide preoperative antibiotics. The IOP does not specify whether the standard of care to which he referred included laparoscopic surgery or open surgery, or both. Nor is it clear how, if at all, the IOP's advice, that the omission of preoperative antibiotics was not relevant to the anastomosis, relates to his more general advice on the standard of practice.

In these circumstances, it is necessary to return the matter to Committee for further consideration and clarification of its decision on this aspect of the complaint.

The Board's only remaining concern is with the question whether the Respondent met the standard of practice concerning the use of preoperative antibiotics.

The matter is being returned to the Committee solely for further consideration and clarification of this important matter.

Pursuant to section 35(1) of the Health Professions Procedural Code, Schedule 2 to the Regulated Health Professions Act, 1991, the Board returns the decision to the Committee and requires it to further consider and clarify its decision concerning the use of preoperative antibiotics and the standard of practice. The Committee's decision to counsel the Respondent on timely documentation of discharge summaries and to take no further action on the other aspects of the complaint is confirmed.

There were 6 more deaths by the bariatric department of this hospital during 2009 and up to Feb. 2010 under similar circumstances— And this past year, a woman who had a hysterectomy bled out before they could get her to the OR. It is almost impossible for me to obtain the details but the Chief Coroner’s Office and the hospital would have them-----these deaths may have been prevented if my daughter’s death was thoroughly investigated the first time.

From someone who worked at the hospital.

“I forgot to let you know that last year a doctor from a university hospital was sent to HRRH to train surgeons for Bariatric surgeries, of course after people died of hemorrhages and they did not know what was happening in OR.”

re: death of daughter who bled to death 12 hours after being released from HRRH

Again, I support this site completely. But it is important for prospective patients to ask the questions that need to be asked.

The College doesn't even agree with its own expert: ie --- their expert stated that the surgeon neglected (this word is used as a verb, the noun would be negligence) to have anti-biotic prophylaxis delivered but the College ignores it
--the experts also states that the low protein count had to have occurred while Terra was hospitalized and the College ignores this ---their expert states that she should not have been released without a bowel movement and of course the College ignores this as well

From Surgeons outside of Canada --- two responses out of 99 and I only sent the the details today

Apparent lapses in care are: 1) Lack of peri-operative antibiotics . 2) Discharging your daughter with ongoing diarrhea of unexplained etiology, 3) Prolonged period of inadequate nutrition, 4) nursing records that appear to be at odds with the physician record of the abdominal exam, 5) failure to distinguish the intra-abdominal catastrophe from the wound infection.

It is self-evident that she was discharged prematurely or she would not have died outside the hospital of a devastating post-operative complication.

my review of the information
you sent me my opinion is that your daughter received suboptimal care
approaching malpractice-at least by US standards. I would have to
assume that Canadian standards are equivalent to US standards but from
the response I read perhaps they are not.

I totally support you but a MIS surgeon failed my daughter. L Klein was the surgeon. Negligence

Please read my blog at: No Accountability or Transparency in Ontario

Great surgeon with a great personality. I felt very comfortable with him from the first meeting.

Did an awesome job with my surgery. No complaints!

Would recommend him to everyone!

I am so pleased with Dr. Laz Klein. I can honestly say he has completely changed my life. Even being 480 lbs. on surgery day, I had absolutely no complications at all. I would not hesitate to recommend Dr. Klein. He works out of Humber River Hospital (Finch Site).

Nice guy, excellent surgeon. Too bad the women at the office he shares with Hagen and Huynh are awful. One repugnant jackass just hung up in my ear.

Sept. 21, 2012


When I first met Dr. Klein I found him to be very open, upfront, and easy to talk to. He took his time and listened to what I had to say and didn't make me feel rushed at all. At my follow up before surgery he took the time to answer my list of questions and explained everything to me in easy to understand terms which you don't often get.
Day of surgery he was awesome very reassuring and kind as I was a upset and sooo nervous, and I found his bedside manner great also.
Post op follow up at his office I had been having trouble and he took time to listen to my concerns and put the appropriate action into place for follow up as I had a stricture.
His office staff are very friendly and helpful. I would highly reccommended him to others that are thinking of having the same surgery....I defiantely felt like and still do that I am in great hands and being well taken care of.

After 17 months from when I started looking into this, I had my first visit with Dr Starr, quite a wait though, so expect to be there awhile. Good thing you don't have to pay for parking He was very nice and personable, unlike a lot of doctors i've seen over the years.

This week has been hell. I've been transferred to Dr Hagen on top of everything - I'm thrilled about Dr Hagen doing my surgery. At least now I know it won't be until at least January.

Dr. Klein seems really knowledgeable. He is an assistant Prof at U.of T. and was one of the key factors in getting Laproscopic surgery at the bariatric program at Humber River Regional Hospital.

He has answered all of my questions(including the stupid ones - without cracking a smile)and I feel really comfortable with him.

Another fantastic point is that he has great staff, and his office runs on time!!

Overall I am really pleased with Dr. Klein, and I will update more after surgery.

My first impression wasn't a good one he seemed rushed and cold like ice, i though t he was some sort of work out buff. Over time i realizeed that he was a man with compassion and wanted to help me he is truly a nice man. His staff is extremly friendly and nice. I least liked the wait times at the office sometimes i had to wait an hour later than my sceduled appointment. Dr.Klien cares about each and every one of his patients. He prefers for you to stay the whole duration in the hospital. I would rate him a 10. Both surgical competence and bedside manner are equally important.
