The ROGER randomised clinical trial compared robotic transabdominal preperitoneal repair (rTAPP) with laparoscopic totally extraperitoneal repair (TEP) for elective primary inguinal hernia. In this single-centre, patient- and investigator-blinded Swiss RCT, 182 patients were randomised 1:1 (mostly male, mean age ~56 years, BMI ~25 kg/m²).
The ROGER randomised clinical trial compared robotic transabdominal preperitoneal repair (rTAPP) with laparoscopic totally extraperitoneal repair (TEP) for elective primary inguinal hernia.
In this single-centre, patient- and investigator-blinded Swiss RCT, 182 patients were randomised 1:1 (mostly male, mean age ~56 years, BMI ~25 kg/m²). The primary endpoint was postoperative pain while coughing at 24 hours.
Results showed no significant difference in pain between approaches (median score 5 for TEP vs 4 for rTAPP, P = 0.431). Postoperative complication rates were also similar (11% vs 10%).
However, key differences emerged:
Operating time was significantly longer with rTAPP (80 vs 64 minutes for unilateral repairs).
Surgeon workload, measured using the NASA Task Load Index, was substantially lower with rTAPP (mean 18 vs 34, P < 0.001).
Thus, while robotic repair did not improve early postoperative pain or reduce complications, it significantly reduced perceived surgical workload—at the cost of longer operative time.
Clinical takeaway: For patients, outcomes are equivalent. For surgeons, robotics may improve ergonomics and reduce fatigue. The decision to adopt robotic repair may therefore depend more on institutional resources and surgeon factors than on short-term patient benefit.
Introduction: Pancreatoduodenectomy remains one of the most complex abdominal operations. Robotic pancreatoduodenectomy (RPD) has been proposed to improve postoperative recovery, but robust randomized evidence has been limited. The PORTAL trial compared robotic and open pancreatoduodenectomy...
Introduction: Surgery is an inherently high-stress profession, where complications, patient deaths, and difficult decisions can lead to burnout, moral injury, and mental health disorders. Inspired by the US Marine Corps' Combat and Operational Stress Control...
Introduction: As surgical techniques and perioperative therapies have advanced, vascular resection during pancreatic cancer surgery has become increasingly common in selected patients with locally advanced disease. This study evaluated the long-term outcomes of venous and...
Introduction: Optimal drain management after pancreatoduodenectomy (PD) remains critical for preventing postoperative pancreatic fistula (POPF) while supporting enhanced recovery. This study proposes a dynamic, risk-adapted algorithm based on intraoperative risk and postoperative biochemical markers. Why...
Introduction: Diverticulitis is a common cause of acute abdominal hospitalization and contributes substantially to healthcare utilization worldwide. While seasonal variation has been recognized in several gastrointestinal and surgical conditions, whether diverticulitis follows a reproducible temporal...
Introduction: Postoperative hypertension is frequently encountered in hospitalized surgical patients and often triggers immediate clinical intervention. Elevated blood pressure readings after surgery may result from pain, anxiety, fluid shifts, medication changes, or physiological stress responses....
