Brief Summary

1. 1.This study looks at whether newer surgical tools-like the da Vinci robotic system-can help patients recover better after major abdominal surgeries. It compares three surgery methods: traditional open surgery, standard laparoscopic (minimally invasive) surgery, and robotic surgery.
2. 2.The research focused on four common operations: Stomach surgery (gastrectomy), Pancreas surgery (pancreatectomy), Liver surgery (hepatectomy) and andWhipple procedure
3. 3.Researchers looked at medical records from 486 patients over five years. They compared how long each surgery took, how much blood was lost, and how many days patients stayed in the hospital.
4. 4.The study wanted to see if robotic and laparoscopic surgeries help patients by making the surgery faster, safer, and with a quicker recovery.
5. 5.The benefits depended on the type of surgery. In many cases, robotic and laparoscopic surgery led to shorter hospital stays, less bleeding, or faster surgeries. These results suggest that using newer technology can help make surgeries safer and recovery easier for patients.

Outcome Measures

Primary Outcomes (2)

• operative time

  The duration of the operation

  From entry into the operating room for anesthesia induction to completion of skin closure at the end of surgery (Day 1, intraoperative period), assessed over an estimated duration of up to 10 hours

• bleeding

  The amount of intraoperative bleeding

  From initiation of surgery (skin incision) to completion of wound closure during surgery (Day 1, intraoperative period), assessed over an estimated duration of up to 10 hours.

Secondary Outcomes (1)

• hospital stay

  From the date of surgery to the date of hospital discharge, assessed up to 55 days postoperatively

Study Arms (1)

Study Population

A population that needs robotic surgery for gastrectomy, liver resection, or pancreatectomy

You may qualify if:

• Adult patients (age ≥ 18 years)
• Underwent one of the following surgeries: gastrectomy, liver resection, or pancreatectomy
• Received surgery at Chung Shan Medical University Hospital between July 2015 and September 2019
• Surgery performed by the general surgery team with experience in open, laparoscopic, and robotic (da Vinci) surgery
• Surgical method included one of the following: open surgery (laparotomy), laparoscopic surgery, or robotic (da Vinci) surgery

You may not qualify if:

• Patients who underwent surgeries outside the specified types (i.e., not gastrectomy, liver resection, or pancreatectomy)
• Patients with incomplete or missing perioperative data (e.g., operative time, blood loss, or hospital stay)
• Patients who underwent combined or staged surgical procedures unrelated to the HPB domain
