Robotic Bariatric Surgery in Mexico: What the Evidence Shows

The robotic bariatric procedure has been performed in selected proven programs in Mexico and from the medical literature, it has been shown that although this approach is considered to be safe, it does not appear to be superior to the traditional laparoscopic approach.  At Renew Bariatrics, the scientific literature is presented to the patients and this gives them an opportunity to make a well-informed decision regarding the technique they wish to use. We suggest that you visit our surgeons page to see our selected surgical partners. 

The surgical system used (e.g., da Vinci) provides the surgeon with a magnified 3D view and wristed instruments, which can be helpful in precise performance in complex or revision cases. However, the data also indicate that robotic surgery tends to be more expensive and more time-consuming than laparoscopic surgery, and that while there is a mixed picture when it comes to complications, this area must be closely tracked. This article reviews the head to head evidence, and then explores the question of which hospitals in Mexico do have a robotic bariatric program available, so you can ask informed questions before booking.

The short answer: Robotic bariatric surgery is a technique that’s just as real as laparoscopic surgery and is gaining in popularity and has Mexican peer-reviewed outcomes data to back it up, but it’s not necessarily the “better” option for every procedure or every patient.

Key takeaways

• Robotic sleeve gastrectomy is associated with an extra 27.5 minutes of operation time and about $5,831 in costs compared to laparoscopic sleeve surgery based on a 2024 meta-analysis (PubMed).
• According to a 2025 MBSAQIP research involving more than 823,000 patients, robotic sleeve gastrectomy was characterized by greater risks of morbidity, leakage, and hemorrhage compared to laparoscopic sleeve, while robotic gastric bypass resulted in a lower risk of morbidity than laparoscopic bypass (PubMed).
• There are three peer-reviewed robotic bariatric surgical case series from Mexico where there were no deaths and low incidences of complications (PubMed; PMC/Cureus; PubMed).
• Robotic gastric bypass rather than robotic sleeve resulted in outcomes that are equal to those of laparoscopic bypass in different systematic reviews (PubMed).
• Da Vinci robotic surgery programs are reported at Hospital Angeles institutions and at Christus Muguerza, although it is not confirmed from publicly available sources that all these facilities use robotic bariatric procedures (Hospital Angeles; Christus Muguerza).
• The choice of the technique is not the most important one, but the surgeon and the hospital’s experience regarding the safety and the volume of cases.

What robotic bariatric surgery actually is

Robotic assisted bariatric surgery is the use of a surgeon-controlled robotic platform, most typically da Vinci, rather than the surgeon’s hand-held laparoscopic instruments. A surgeon sits at a console and controls the movement of robotic arms carrying a camera and the wristed surgical tools through small incisions made into the abdomen. The sleeve gastrectomy, gastric bypass or revisional procedure is performed the same, the only difference is the instrument control method.

The 3D magnified view and wristed movement are proposed to aid in fine suturing in technically demanding or revisional surgical procedures. Critics point out that it imposes “docking” time before the operation and extends the overall operating room time, and that facility costs will be higher per case. Below are the facts that prove both sides.

Robotic vs. laparoscopic bariatric surgery: the comparison table

The clearest way to see the trade-offs is side by side. The table below is based on the 2024 meta-analysis of sleeve gastrectomy, and the systematic review of gastric bypass, and the large national outcomes study in 2025.

As you can see from the pattern that emerges, the advantage (or the disadvantage) of the robot in the marketing materials is dependent upon the procedure you’re undergoing. In the case of sleeve gastrectomy, the massive 2025 study of 823,902 cases actually showed higher complication rates with robotic surgery compared to laparoscopic (PubMed). In gastric bypass, the same study revealed the opposite: The robotic bypass was found to have fewer hemorrhages and lower morbidity compared to the laparoscopic bypass (PubMed). Another systematic review of gastric bypass techniques found that “RRYGB is not superior to LRYGB” (systematic review) though there were similar outcomes.

This is why an honest response to “is robotic bariatric surgery better?” has to begin with “for which procedure and how?”

Why the sleeve and bypass results diverge

The percentage of sleeve cases used for robotic surgery has increased from 6.7% to 29.5% from 2015 to 2022, and the percentage of bypass cases used for robotic surgery has increased from 6.9% to 31.8% (PubMed). However, as the number of sleeve gastrectomies increased, the aggregate national data indicated increased morbidity, leak and bleeding rates compared to laparoscopic sleeve. In bypass — a more complicated procedure and reconstruction of the intestine — the increased dexterity of wristed instruments may mean a more consistent advantage, similar to the lower odds of morbidity and bleeding found in the same data set (PubMed).

It does not imply that robotic surgery is dangerous – the number of complications in either group is small absolute numbers. It means that the instrument platform should reflect the complexity of the operation, and not generalizations that robotics itself is more complex.

The three Mexico-specific robotic bariatric studies

Even though large clinical trials have been conducted in the U.S., it is also necessary to consider local cases at Mexican facilities. At the moment, there are three published case series in peer-reviewed literature that focus on the safety and efficacy of robotic weight loss procedures at Mexican hospitals.

1. Super-obese patients at Centro Médico Nacional 20 de Noviembre

In 2024, research was carried out among 44 obese patients (BMI 50 or above) who underwent the da Vinci robot-assisted surgery at the Centro Médico Nacional 20 de Noviembre, a renowned ISSSTE facility situated in Mexico City between 2018 and 2023 (PubMed). 

Patients with a BMI of 50-59.9 had a mean total operative time of 95.73 minutes (docking 10.09 min and console 86.23 min), while patients with a BMI ≥60 had a mean total operative time of 92.2 minutes (docking 9.80 min and console 82.4 min) (PubMed). No serious complications, no deaths, and patients demonstrated excellent weight and BMI improvements over 54 months of follow-up, with some weight recurrence after 24 months (PubMed).

2. Robotic revisional bariatric surgery, also at 20 de Noviembre

A separate study published in Cureus looked at 90 patients who underwent revisional bariatric surgery at the same ISSSTE hospital from January 2021 to December 2024, comparing patients who had robot-assisted surgery (62 patients, 68.9%) with those who had laparoscopic surgery (28 patients) (PMC/Cureus). 

The mean operative time was 193.1 ± 25 minutes for robot-assisted surgery and 145.6 ± 18 minutes for laparoscopic surgery (p<0.0001), which is a clinically significant difference in operative time for revisional cases compared with primary surgery, which is technically more difficult (PMC/Cureus). 

There were no mortalities, the average length of stay was 2.1 ± 1 days, and the rate of conversion was 8.1% (PMC/Cureus), which is significant because all of these complications occurred in the laparoscopic group, not the robotic group. One of the more positive points regarding robotic surgery in the revisional setting is that there is a higher value in added precision in this context.

3. A Mexican medical-tourism center’s robotic case series

Third peer-reviewed series is about robotic-assisted bariatric surgery in a Mexican hospital treating medical tourism setting during the time period of January 2023 through May 2025 and including 94 patients (PubMed). Mean age was 42.8 years, mean BMI was 41.8 while 84% of patients were females; sleeve gastrectomy was done in 56.4% of cases (PubMed). Mean docking time was 7.6 min; total operation time was 111.6 min; console time was 69.6 min, with a decrease in docking time due to learning curve (PubMed). This might be the best evidence supporting the possibility of robotic bariatric surgery in medical tourism care models rather than in large academic hospitals only.

All three series have common features – total operation times varying between 90 and 195 minutes depending on the complexity of the procedure, no deaths among 228 patients overall, and a low complication rate. However, these are case series, not randomized controlled trials, which means that these are facts, not guaranteed results of any particular center.

Which Mexican hospitals have documented Da Vinci programs?

That’s where it’s important for patients to be able to distinguish between what has been marketed and what has been published or otherwise confirmed. There are two hospital systems with publicly documented, verifiable da Vinci robotic-surgery programs in Mexico:

Hospital Angeles claims to be a leader in advanced surgical technology in Mexico and uses da Vinci robotic surgical systems. In addition, Hospital Angeles has Joint Commission International (JCI) Gold Seal accreditation in multiple facilities such as Pedregal, Lomas, Puebla, Universidad, Acoxpa and Centro Sur Querétaro (Hospital Angeles JCI page). The publicly available program page doesn’t say how many robots the system is using, where exactly they are being used, or if bariatric surgery is one of the specialties using the platform (which is the case at the hospital, but should be confirmed on a case-by-case basis instead of taken for granted).

Christus Muguerza announced the launch of the “Programa de Cirugía Robótica de Mínima Invasión” (Minimally Invasive Robotic Surgery Program) in the following surgical specialties: urology, transplants, obstetrics and general surgery (Christus Muguerza press release). It does not specifically mention bariatric or metabolic surgery at the bottom of the list, and should be treated as a general-surgery robotic program at the moment until a patient or coordinator verifies that bariatric surgery is available for their specific program.

In addition to the two systems described above, the best documented experiences with robotic bariatrics in Mexico are from the academic public-sector hospital, Centro Médico Nacional 20 de Noviembre (ISSSTE) in Mexico City, as described in the two studies above, and one undisclosed medical-tourism center described in the third study (PubMed; PMC/Cureus; PubMed). 

However, the current literature did not include any peer-reviewed robotic-bariatric case series by any medical-tourism clinic that specifically mentioned the clinic by name, though this does not mean it is not possible to exist, just that the available sources above were the only ones that were reviewed at this level of specificity. Patients should inquire from the hospital directly about its size and experience with the procedure in question, as well as outcomes data — preferably published or self-aggregated.

What this means if you’re choosing between robotic and laparoscopic

Most patients who are looking at a standard primary sleeve gastrectomy should consider laparoscopic surgery to be a safe bet, as the evidence has shown that it is quicker, less expensive, and associated with fewer (not more) complications as compared to robotic sleeve surgery (MBSAQIP, 2025). 

But in the case of choosing gastric bypass surgery or if you require a revision due to having undergone surgery before, then the use of a robotic system becomes significantly more relevant since improved visualization and articulation of the robot makes clinical outcomes in these highly complicated operations completely equal, and sometimes better than the traditional laparoscopy; this is especially noted in the Mexican revisional study in which the robotic group had no complications (PMC/Cureus).

None of this is to be used in selecting a hospital due to the presence of a robot and not because of its track record. In the field of bariatric surgery as a whole, surgeon and center case volume consistently has been one of the most repeatable safety predictors.

How Renew Bariatrics approaches this

Renew Bariatrics collaborates with accredited hospitals and board-certified surgical teams. In addition, we recommend that you pose evidence-based questions regarding your surgery technique — such as whether or not the procedure is going to be performed with the use of robotic or laparoscopic surgical devices. Renew Bariatrics does not try to persuade you into undergoing robot-assisted surgery simply because the technology is available; rather, we aim to select the surgical method that is the most effective in your case, based on the same type of peer-reviewed data, as outlined in this article. 

Every consultation provided by us involves consideration of the surgeon’s qualifications, hospital accreditation and postoperative plan that you can choose from based on evidence-based information and not by marketing claims. You can see our current surgical partners on our bariatric surgeons showcase.

Frequently asked questions

Is robotic bariatric surgery safer than laparoscopic surgery? It will be based on what kind of surgery is performed. According to a comprehensive study involving more than 823,000 patients in 2025, the robotic gastric sleeves had a higher incidence of problems, leaks, and bleeding compared to the laparoscopic sleeves. On the other hand, the number of complications and bleedings was lower for robotic gastric bypass surgeries (PubMed). Each bariatric procedure has different answers.

Does robotic bariatric surgery cost more? Yes. In one meta-analysis study conducted in 2024, it was found that the cost for a robotic sleeve gastrectomy is, on average, $5,831 higher than a traditional laparoscopic sleeve gastrectomy. It was also observed that there could be 27.5 more minutes in operating time for a robotically assisted procedure (PubMed). 

Are there hospitals in Mexico with documented robotic bariatric programs? Yes, indeed. There are peer-reviewed clinical journals that feature the success of a robotic bariatric surgery conducted on high-BMI patients and revisional patients at the Centro Médico Nacional 20 de Noviembre in Mexico City (PubMed; PMC/Cureus). A third peer-reviewed study reports bariatric surgery using robots at an unnamed medical-tourism facility in Mexico (PubMed). Hospital Angeles and Christus Muguerza also have more extensive da Vinci robotic surgery programs, but there is not any public information confirming that bariatric surgery is performed at all centers (Hospital Angeles; Christus Muguerza).

Is robotic surgery better for revisional bariatric surgery specifically? Initial Mexican-specific evidence is promising. All 90 patients undergoing revisional bariatric surgery at a hospital in Mexico City had a complication (3.3%) with none of the patients in the robot-assisted group (PMC/Cureus).  It is reassuring to see that the robot helps add an extra layer of precision during the revisions, but it is a small-scale, non-randomized cohort study

How long does robotic bariatric surgery take compared with laparoscopic? It usually takes longer. A meta-analysis showed that robotic sleeve gastrectomy took an average of nearly 28 minutes longer than laparoscopic sleeve gastrectomy (PubMed), while a study of revisional surgery in Mexico revealed a mean difference of 193.1 minutes for robot-assisted SLEEVE compared to laparoscopic SLEEVE (PMC/Cureus).

Does robotic surgery lead to less weight loss or more weight loss? Evidence available indicates that there is no difference in weight loss between robotic and laparoscopic procedures. In the 2024 sleeve gastrectomy meta-analysis, there were no differences in the extent of weight loss in the robotic vs. non-robotic groups and similar rates of complications (PubMed) while the Mexico-based super-obesity study showed that patients in the robotic group experienced significant weight and BMI reductions after 54 months, with some weight recurrence after 24 months  (PubMed).

Should I choose a hospital in Mexico specifically because it has a robotic surgery system? No, you should never do something just for the sake of using some new technology. Sure, there are lots of benefits that can be gained from having a robot as your surgical platform, but the thing is, those benefits are very procedure-specific and the experience of the surgeon is a lot more important than the platform itself. Don’t forget to check on the bariatric surgery case volume.

Is robotic bariatric surgery still considered experimental? No. Robotic weight-loss surgery is a safe and proven surgical procedure that boasts considerable data worldwide and has had hundreds of thousands of success stories proven by research. During the period from 2015 to 2022, the proportion of robotic sleeves and bypass surgeries out of the total number of procedures done reached nearly one-third in the USA (PubMed). It is an established, FDA-cleared surgical platform rather than an experimental technology, though its comparative advantage over laparoscopic surgery still varies by procedure.
