About Dr. Lucas Bassi
Dr. Lucas Bassi works to evaluate conditions of the digestive system and intestinal and coloproctological symptoms that may require specialized monitoring. In the context of the Women's Medicine Clinic, its work can be integrated into the care of patients with endometriosis, pelvic pain, intestinal symptoms, bowel movements, suspected intestinal involvement and the need for a second surgical opinion.
The purpose of the page is to present your work within the clinical team, without replacing a medical consultation and without anticipating treatment recommendations. The assessment considers symptoms, history, available tests, patient needs and integration with other specialties when appropriate.
Areas of activity
Digestive System Surgery
Assessment of digestive tract conditions that may require clinical monitoring, additional investigation or surgical discussion according to the patient's diagnosis and history.
Coloproctological conditions
Assessment of intestinal and anorectal symptoms, such as pain, bleeding, bowel movements, constipation, fistulas, fissures and hemorrhoids, as confirmed by the clinic.
Intestinal endometriosis
In patients with endometriosis and intestinal symptoms, integrated assessment can help discuss exams, imaging findings, symptoms, care alternatives and the need or not for a surgical approach.
Abdominal wall hernias
Assessment of pain, bulging or suspected hernia, with individualized discussion about follow-up, exams and treatment possibilities when indicated.
Gallbladder
Assessment of symptoms or tests related to the gallbladder, such as gallstones, always according to clinical history and medical indication.
Anorectal diseases
Assessment of symptoms such as anal pain, bleeding, fissures, fistulas, hemorrhoids and bowel movements, without replacing in-person consultation when necessary.
Surgical second opinion
Review of diagnosis, exams, surgical indication, risks, benefits, alternatives and doubts before making a treatment decision.
Digestive care integrated with women's health
Digestive, intestinal and pelvic symptoms can be related to different women's health conditions. In some cases, evaluation of the digestive system and coloproctology may be important for patients with endometriosis, pelvic pain, constipation, change in bowel habits, suspected intestinal involvement or multidisciplinary surgical planning.
Not every intestinal symptom in women has a gynecological origin. The assessment helps to interpret signs, exams and clinical context on an individual basis.

Frequently asked questions about care with Dr. Lucas Bassi
What is Dr. Lucas Bassi’s area of expertise?
Dr. Lucas Bassi is part of the clinical staff of Clínica Medicina da Mulher, with activities related to digestive system surgery and the evaluation of intestinal symptoms and coloproctological conditions. The page uses this description in an institutional and cautious way, while CRM, RQE and registered specialty await documentary validation before being published.
Does Dr. Lucas Bassi treat patients with intestinal endometriosis?
Patients with endometriosis and bowel symptoms can seek evaluation to discuss symptoms, exams, imaging findings, clinical history, and need for integrated care. This consultation does not automatically indicate surgery. The conduct depends on the context of each patient and may involve other areas of the clinic.
When to look for a digestive system surgeon?
The evaluation can be considered when there are persistent digestive symptoms, changes in exams, suspected hernia, complaints related to the gallbladder, abdominal pain or doubts about a surgical indication already received. The objective is to interpret symptoms and exams carefully, discuss alternatives and define next steps depending on the diagnosis.
When to seek coloproctological evaluation?
Coloproctological evaluation can be useful in symptoms such as bleeding during bowel movements, anal pain, fissures, fistulas, hemorrhoids, constipation, diarrhea or persistent changes in bowel habits. These signs do not indicate a single cause. The consultation helps to organize hypotheses, review exams and guide the necessary investigation.
Can intestinal symptoms in women be related to endometriosis?
They can, but not all intestinal symptoms in women have a gynecological origin. Pelvic pain, constipation, diarrhea, bloating or pain when having a bowel movement can have different causes. When endometriosis is suspected, integrated assessment can help relate symptoms, menstrual cycle, exams and the need for multidisciplinary monitoring.
Does all intestinal endometriosis require surgery?
No. The presence of intestinal endometriosis or suspicion of intestinal involvement does not mean that surgery will be necessary. The decision depends on symptoms, location, exams, history, patient goals and assessment shared between specialties. The consultation serves to discuss possibilities, limits, risks and care alternatives.
What to bring to the appointment?
Bring reports, available images, colonoscopy if available, laboratory tests, medical reports, list of medications, previous surgeries and a summary of symptoms. There is no need to turn the first query into an extensive sending of sensitive data. The team can advise, when necessary, on the best way to present documents.
Can the consultation be a second opinion?
Yes. The consultation may focus on a second opinion to review exams, diagnosis, surgical indication, risks, benefits, alternatives and doubts before making a decision. This process does not disqualify previous professionals and does not promise a change in conduct. The analysis depends on the available material and individualized assessment.
Can the service be provided via teleconsultation?
The clinic can advise on teleconsultation depending on availability, clinical need and applicable rules. Some digestive, coloproctological or surgical situations require in-person consultation, physical examination or detailed image review. The service team will indicate the most appropriate format for each case before scheduling.
Does Dr. Lucas Bassi perform robotic or laparoscopic surgery?
This page does not confirm specific procedures, surgical techniques or technologies without institutional validation. If there is any doubt about robotic, laparoscopic surgery or another type of approach, the patient should talk to the team when scheduling and discuss the indication in consultation, considering risks, benefits, limits and alternatives.
Which clinic specialties can work alongside it?
Depending on the case, care may involve gynecology, endometriosis, gynecological surgery, pain management, nutrition, urogynecology, oncology and other areas. This integration does not mean that all patients will need multiple appointments. The need for each specialty depends on the symptoms, exams and goals of care.
How does scheduling work?
Scheduling is done by the Women's Medicine Clinic team, preferably via WhatsApp indicated on this page. When you get in touch, state that you would like a consultation with Dr. Lucas Bassi and, if applicable, mention intestinal symptoms, suspected intestinal endometriosis, hernia, gallbladder or a second opinion.
Does the doctor work at the same address as the Women's Medicine Clinic?
The in-person service is presented as linked to the Women's Medicine Clinic, in São Paulo. Address, schedule, availability and format of the appointment must be confirmed with the team at the time of scheduling. The page preserves the site's institutional channels to avoid divergent or outdated information.
Are CRM and physician EQR available?
In this version, CRM and RQE were left pending institutional validation. This data should only be displayed when confirmed by a documentary source, CMS or by the clinic team. This caution avoids publishing incorrect numbers and keeps the profile in line with good medical information practices.
Institutional update and validation
Institutional profile updated in July 2026. Specific professional information, such as CRM, RQE, training, positions, companies, hospitals and procedures, must be reviewed by the Women's Medicine Clinic team before publication.
