Key Takeaway
Note that massive hemorrhage occurred in 57.1% of patients undergoing resection of giant abdominal masses in this retrospective cohort.

This retrospective cohort study evaluated perioperative characteristics and outcomes in 21 patients undergoing resection of giant abdominal masses. The population included cases with tumors originating from the abdominal wall (8 cases, 38.10%), abdominopelvic cavity (6 cases, 28.57%), and retroperitoneum (7 cases, 33.33%). Pathological diagnoses revealed malignant tumors in 11 cases (52.38%) and borderline tumors in 7 cases (33.33%).

All patients received general anesthesia. Single-lumen endotracheal intubation was utilized in 16 cases (76.2%). Intraoperative monitoring included invasive arterial pressure monitoring in 16 cases (76.2%), central venous pressure monitoring in 15 cases (71.4%), and FloTrac-based cardiac output monitoring in 8 cases (38.1%). Operative duration ranged from 110 to 440 minutes.

Safety and tolerability data indicate that massive hemorrhage (≥ 1,000 mL) occurred in 57.1% of patients. Postoperative ICU stay ranged from 0 to 12 days, while postoperative hospital stay ranged from 7 to 58 days. Patients with retroperitoneal masses exhibited higher preoperative ASA physical status classification, larger tumor diameter, and longer ICU and hospital stays compared to others. Similarly, those with malignant tumors were older, had higher ASA classification, experienced longer operative duration, and had prolonged ICU stays.

Limitations include the retrospective design and lack of a comparator group. The practice relevance suggests that anesthetic management requires individualized strategies, preoperative multidisciplinary consultation, and interventional embolization may reduce surgical risk. Intraoperative advanced hemodynamic monitoring and meticulous volume management warrant particular attention.

Imagine waking up to find a mass the size of a watermelon pressing on your organs. Now imagine that mass is so large it requires a major surgery to remove. This is the reality for patients with giant abdominal tumors.

These tumors are rare but dangerous. They can grow anywhere from 15 to 50 centimeters across. That is huge. They can push on your intestines, block blood flow, or press on your spine.

Most of these growths are cancerous or borderline cases. That means they need careful handling. The problem is that standard surgery plans often fail for these massive cases. Patients face high risks of bleeding and long recovery times.

The Surprising Shift

Doctors used to treat these cases with a one-size-fits-all approach. They would just try to cut out the tumor. But here is the twist: this new analysis shows that size alone changes everything.

Patients with tumors in the back of the abdomen (retroperitoneum) are sicker before surgery. They have higher risk scores and need more time in the hospital. Malignant tumors also mean older patients and longer operations.

What Scientists Didn't Expect

The biggest surprise was how much blood loss occurs. More than half of the patients lost over 1,000 milliliters of blood during surgery. That is a lot of blood.

Think of the body like a complex plumbing system. When a giant tumor sits inside, it blocks the pipes. Surgeons have to cut through tough tissue while keeping the system stable.

The key is monitoring. Doctors need to know exactly how much blood is flowing. They use special tubes in the arteries to watch pressure. They also track heart output to ensure the heart is not overworking.

Researchers looked at 21 patients treated between 2016 and 2024. All 21 patients received general anesthesia. Most had a standard breathing tube.

However, many had advanced monitoring. About three-quarters had arterial lines. Over 70% had central venous pressure checks. Some even had cardiac output monitors to track blood flow in real time.

The most important finding is about safety. Massive bleeding happened in 57% of cases. This is not normal for routine surgeries. It requires a very skilled team.

Patients with tumors in the back of the abdomen stayed in the ICU longer. Their hospital stay ranged from one to two months. The surgery itself took between 110 and 440 minutes. That is two to seven hours of intense work.

But there is a catch.

This is where things get interesting. The study suggests that doing nothing extra is not an option.

The data points to a clear need for teamwork. Before surgery, doctors must talk to specialists. They might use embolization to block blood vessels feeding the tumor. This reduces bleeding risk during the cut.

Advanced monitoring is not optional. It is essential. Without it, the team cannot react fast enough to sudden changes in blood pressure or heart function.

If you or a loved one has a giant abdominal mass, talk to your doctor about a plan. Do not assume a standard surgery is enough. Ask about pre-surgery embolization. Ask about advanced monitoring during the operation.

These steps may reduce risk. They might shorten your hospital stay. But remember, this is still based on a small group of 21 patients.

This research highlights that every case is unique. Future trials will likely test new embolization techniques. They will also look at better ways to manage blood loss.

Until then, the focus remains on individualized care. Doctors must tailor the plan to the tumor's size and location. Careful planning saves lives in these difficult cases.

ObjectiveTo summarize perioperative anesthetic management in patients undergoing resection of giant abdominal masses.MethodsPerioperative data from 21 patients who underwent resection of giant abdominal masses between January 2016 and December 2024 were retrospectively analyzed. Descriptive statistical methods and stratified comparative analyses were applied to evaluate perioperative characteristics and outcomes.ResultsThe maximum tumor diameter ranged from 15 to 50 cm. Tumors originated from the abdominal wall in 8 cases (38.10%), the abdominopelvic cavity in 6 cases (28.57%), and the retroperitoneum in 7 cases (33.33%). Pathological diagnoses predominantly included malignant tumors in 11 cases (52.38%) and borderline tumors in 7 cases (33.33%). General anesthesia was administered to all 21 patients, with single-lumen endotracheal intubation used in 16 cases (76.2%). Intraoperative monitoring consisted of invasive arterial pressure monitoring in 16 cases (76.2%), central venous pressure monitoring in 15 cases (71.4%), and FloTrac-based cardiac output monitoring in 8 cases (38.1%). Operative duration ranged from 110 to 440 min, and massive hemorrhage (≥ 1,000 mL) occurred in 57.1% of patients. Postoperative intensive care unit (ICU) stay ranged from 0 to 12 days, while postoperative hospital stay ranged from 7 to 58 days. Stratified analyses indicated that patients with retroperitoneal masses presented with higher preoperative American Society of Anesthesiologists (ASA) physical status classification, larger tumor diameter, and longer ICU and hospital stays. Patients with malignant tumors were older and demonstrated higher ASA classification, longer operative duration, and prolonged ICU stay.ConclusionAnesthetic management for resection of giant abdominal masses requires individualized strategies. Preoperative multidisciplinary consultation and interventional embolization may reduce surgical risk. Intraoperative advanced hemodynamic monitoring and meticulous volume management warrant particular attention.
