Background: Minimally invasive surgery, such as laparoscopic adrenalectomy and robotic adrenalectomy, has become a treatment of choice for benign adrenal tumors. Efforts are ongoing to minimize the invasiveness of the procedure and to reduce the number of port sites. The primary endpoint of this study was the safety and feasibility of a reduced-port site technique for robotic posterior retroperitoneal adrenalectomy (RPRA).
Methods: This study retrospectively analyzed 74 RPRAs performed by a single surgeon, including 30 conventional three-port site early-phase RPRAs, 30 three-port site late-phase RPRAs, and 14 reduced-port site RPRAs. Reduced-port site RRPA was defined as using two port sites: one for a multi-glove port and one for an additional side port. The clinicopathological features and surgical outcomes were compared in these three groups.
Results: No major complications were observed following RPRA in the three groups of patients. Operation time, pain score, and hospital stay did not differ significantly among these three groups.
Conclusions: RPRA using a reduced-port site system was safe and feasible and may be a good alternative to conventional three-port site RPRA for benign adrenal tumors in certain situations.

Background: This study demonstrates our experience of single-port robotic posterior retroperitoneal adrenalectomy (RPRA) using the da Vinci SP robot system and evaluates its technical feasibility and surgical outcomes.
Methods: We conducted a retrospective analysis of 250 RPRAs, including 117 conventional 3-port RPRAs, 103 reduced 2-port RPRAs, and 30 single-port RPRAs. Each RPRA type was compared by analyzing 30 patients in the early phase of surgery.

Background: Minimally invasive pancreatic surgery the multi-port approach has become a primary surgical method for distal pancreatectomy (DP) due to its advantages of lower wound pain and superior cosmetic results. Some studies have applied reduced-port techniques for DP in an attempt to enhance cosmetic outcomes due to the minimally invasive effects. Numerous recent review studies have compared multi-port laparoscopic DP (LDP) and multi-port robotic DP (RDP); most of these studies concluded multi-port RDP is more beneficial than multi-port LDP for spleen preservation.

Background: The purpose of this study was to clarify the oncological safety of reduced-port laparoscopic surgery (single-incision plus one port) (RPS) for patients with rectal cancer.
Methods: The clinicopathological data of 63 selected patients with clinical Stage I-III (T1-3 and N0-2) rectal cancer who underwent RPS of radical anterior resection between 2012 and 2017 were retrospectively analyzed. The median distance of tumor from anal verge was 11 cm.

Total pleural covering is implemented to reinforce the visceral pleura with surgical sheets. It has been adopted for diffuse cystic lung diseases such as lymphangioleiomyomatosis to prevent pneumothorax and has achieved good results. The procedure is technically demanding, because it is difficult to cover the entire visceral pleura without disarrangement and jamming of surgical sheets, especially during thoracoscopic surgery, where grasping of a wrong site might happen when unfolding the sheets.
