What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study compares pain levels after two types of minimally invasive colon surgery: robotic and laparoscopic. About 80 adults having elective colon cancer surgery will take part. Researchers will measure pain at several time points after surgery and track recovery, complications, and quality of life for up to a year. The goal is to see if robotic surgery leads to less pain and faster recovery.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
robotic surgery and laparoscopic surgery
What this could lead to
If robotic surgery proves less painful, hospitals may adopt it more widely to improve patient comfort and speed up recovery after colon surgery.
What could go wrong
This is a small, non-randomized study with only 80 patients, so results may not apply to everyone. The two groups may differ in ways that affect pain, and the study cannot prove cause and effect.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients (≥18 years) undergoing elective colorectal surgery (right or left colon resection) for malignant disease at the Hospital General Universitario Gregorio Marañón (Madrid, Spain), following the hospital's Enhanced Recovery After Surgery (ERAS) protocol (RICA program). All participants must meet strict inclusion criteria, including cognitive capacity and ASA I-III classification, and must consent to participate. Patients will receive either laparoscopic or robotic surgical approach based on surgical planning and equipment availability. The study will exclude individuals with prior chronic opioid use, certain comorbidities, or those requiring open surgery or multivisceral resection.

Ages

Inclusion Criteria: * Adults aged 18 years or older * Signed informed consent * Meeting inclusion requirements of the hospital's Enhanced Recovery Protocol (RICA program), including: * Adequate cognitive status * ASA (American Society of Anesthesiologists) classification I, II, or III * Elective colon surgery (right or left hemicolectomy) for malignant disease * Planned laparoscopic or robotic surgical approach * Preoperative evaluation completed as per RICA protocol (nutritional, nursing, anesthetic, and pharmacy assessments) Exclusion Criteria: * Patients with a preoperative decision for open surgery * Patients undergoing rectal surgery (partial or total mesorectal excision without protective stoma) * Patients with inflammatory bowel disease requiring colorectal resection * Patients requiring multivisceral resection due to oncologic indications identified intraoperatively * Extraction incision different from Pfannenstiel approach * Current or past history of chronic opioid use or opioid abuse * Current or past history of benzodiazepine use or abuse * Chronic use of analgesics for other comorbid medical conditions * Current or past history of recreational drug use or abuse * Non-compliance with the RICA protocol, including: * Lack of preoperative nutritional, nursing, anesthetic, or pharmacy evaluation * Non-adherence to preoperative care protocols (e.g., premedication, fasting, carbohydrate loading, thromboembolism prophylaxis, antibiotic prophylaxis, anesthetic care guidelines)
