In a medical milestone, surgeons have documented the first case of a revisional metabolic procedure performed entirely through Regional Anesthesia Bariatric Surgery. Traditionally, clinicians manage complex procedures like the Roux-en-Y gastric bypass (RYGB) using general anesthesia. However, this novel approach utilizes combined thoracic spinal-epidural anesthesia (CTSEA) to minimize respiratory risks. Consequently, the case highlights a paradigm shift in how anesthesiologists approach high-risk patients with obesity.
The case involved a 41-year-old female patient suffering from weight regain and reflux after a previous sleeve gastrectomy. Her body mass index (BMI) was 37.1 kg/m². Notably, the patient requested regional anesthesia to avoid the potential complications of general anesthesia. The surgical team successfully converted her sleeve gastrectomy to an RYGB under CTSEA and bilateral superficial cervical plexus blocks. These blocks specifically helped prevent shoulder pain during the laparoscopic inflation phase.
The outcomes of this approach were remarkably positive for the patient and the surgical team. For instance, the patient ambulated and resumed oral intake within hours of the procedure. Moreover, the medical team discharged her on postoperative day one. By avoiding systemic opioids, the patient experienced excellent pain control without typical narcotic side effects. Furthermore, the surgeons reported high satisfaction with the operating conditions and patient cooperation. This feasibility suggests that regional techniques are viable alternatives for selected complex cases.
CTSEA is an advanced regional technique that provides deep surgical anesthesia for the abdomen while keeping the patient conscious. It combines spinal and epidural methods to ensure stable hemodynamic conditions during complex bariatric procedures without requiring a ventilator.
While primary bariatric surgeries occasionally use regional blocks, this case represents the first successful laparoscopic revisional surgery performed entirely without general anesthesia. This proves the feasibility of regional techniques in technically challenging, long-duration metabolic conversions where general anesthesia risks are higher.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
