Patient Reviews, Ratings

“I also had a gastric sleeve performed by doctor Alejandro Lopez and I must say it was very different experience than the others posted.I also am from Canada and traveled to San Diego. I was picked up by a driver who was very polite,cautious when driving (I’m usually a nervous passenger and I can say I was at ease!) We were brought to the Marriott the first day ,met with Sandra, had blood tests done she told us next am we would be picked up at 8 am sharp and did the EKG then off to Vida for surgery. Yes the place for EKG is small….oh well I didn’t lose sleep over it. My main concern was where i was getting my surgery I wanted it to be EXTREMELY clean and that it was. The doctor came to speak with me before the surgery ,he is a very caring doctor (and very smart as he is the one who teaches others!!! ) Surgery went great within hours I was up and walking. They actually do three leak test on you.One when you are in OR ,one the first night in hospital and the following day they did another.For me the leak test again wasn’t a big issue at how clean it was(it was a paper cup they give you,you stand there and an X-Ray is taken.) There was talk that hopefully soon these tests could be done at Vida where you have your surgery. Sandra is an amazing lady that goes beyond her call of duty (I called her at 11 pm to get some Imodium and within 15 minutes she was there with meds in hand). When you take a moment to think how much this lady those for all the patients …yes she can forget some things …shes only human shes a driver a caretaker a nurse a friend a shoulder to cry on and the list goes on! Like anything and anyone …we each have our expectations and each have our own opinions…. I didn’t have an infection but i made sure I cleaned my incisions! and I drank the water I was told to drink …those are things that are NOT the fault of the doctor! I have referred a few people and i will continue to refer people to Dr. Alejandro Lopez.”

“On 1/3/14 I wired $5,550 to Cathy to prepay for the LAP-BAND to gastric sleeve surgery performed by Dr. Alejandro Lopez in Puerto Vallarta, MX on January 17, 2014. I emailed 1, 2, 6 and 11 mo. post-op followups with only an 11 lb reported weight loss and subsequent weight gain despite following the post-op diet. I knew something was very wrong when I did not experience restriction and I was frequently hungry. This surgery, when performed correctly, it supposed to resemble a cigar (vs. an hourglass shape which I now have) and the fundus wasn’t removed (which houses the hunger hormone, Ghrelin). On 12/17/14 my endoscopy confirmed that the surgery was performed incorrectly, indicating a “Significantly dilated gastric sleeve”, especially in the fundus in body, measuring 15cm (widest diameter) by 3cm (smallest). I emailed the endoscopy report to Dr. Alejandro Lopez. His response on July 24, 2014 was ” You need think about it if you are not success with restriction procedure you will need something else like bypass”. THIS IS CLEARLY MALPRACTICE. Dr. Lopez has not made any attempts to reimburse me for his malpractice and now I will need a corrective surgery.”

“Read if you REALLY want to know what goes on for your weight loss surgery in Tijuana. I went to Tijuana to see Dr. Alejandro Lopez for my surgery revision gastric bypass on April 6th. I did know I was in the risk of having to have another open surgery again, since my original one was done open. I ended up in the hospital when I came home. My surgery site was getting infected and very dehydrated. I was checked out and all is good now. I am under Bariactric doctors care. Here is what I will say to sum up, do not by any circumstance go alone. Don’t do revision surgery in Mexico I feel to risky. And go other location then Tijuana. Place seems very unsafe. Most people go for sleeve and get 3 or 4 stitches. So risk is minimal. All in all I am lucky when I refused to pay more that I came home safe. Sorry so long but this is the entire story so you can make a very informed decision to go or not go.”
