Our initial single port robotic cholecystectomy experience: A feasible and safe option for benign gallbladder...

Although single-port laparoscopic cholecystectomy has been performed for over 25 years, it is still not popular. The narrow working space used in this surgery limits the movement of instruments and causes ergonomic challenges. Robotic surgery not only resolves the ergonomic challenges of single-port laparoscopic surgery but is also considered a good option with its additional technical advantages, like a three-dimensional display and not being affected by tremors. However, the extent to which these technical and ergonomic advantages positively affect the surgical outcomes and how safe the single-port robotic surgeries need to be assessed for each particular surgery.

To evaluate the feasibility and safety of single-port robotic cholecystectomy for patients with cholelithiasis.

The electronic records of the first 40 consecutive patients with gallbladder lithiasis who underwent single-port robotic cholecystectomy from 2013 to 2021 were analyzed retrospectively. In addition to the demographic characteristics of the patients, we analyzed American Society of Anesthesiologists (ASA) scores and body mass index. The presence of an accompanying umbilical hernia was also noted. The amount of blood loss during the operation, the necessity to place a drain in the subhepatic area, and the need to use grafts during the closure of the fascia of the port site were determined. Hospital stay, readmission rates, perioperative and postoperative complications, the Clavien-Dindo complication scores and postoperative analgesia requirements were also evaluated.

The mean age of the 40 patients included in the study was 49.5 ± 11.6 years, and 26 were female (65.0%). The umbilical hernia was present in 24 (60.0%) patients, with a body mass index median of 29.3 kg/m² and a mean of 29.7 ± 5.2 kg/m². Fifteen (37.5%) of the patients were evaluated as ASA I, 18 (45.0%) as ASA II, and 7 (17.5%) as ASA III. The mean bleeding amount during the operation was 58.4 ± 55.8 mL, and drain placement was required in 12 patients (30.0%). After port removal, graft reinforcement during fascia closure was preferred in 14 patients (35.0%). The median operation time was 93.5 min and the mean was 101.2 ± 27.0 min. The mean hospital stay was 1.4 ± 0.6 d, and 1 patient was readmitted to the hospital due to pain (2.5%). Clavien-Dindo I complications were seen in 14 patients (35.0%), and five (12.5%) complications were wound site problems.

In addition to the technological and ergonomic advantages robotic surgery provides surgeons, our study strongly supports that single-port robotic cholecystectomy is a feasible and safe option for treating patients with gallstones.
