RESUMO
BACKGROUND: The aim of this study was to evaluate the initial experience of a single robotic center with the Senhance® robotic systems (TransEnterix Surgical Inc, Morrisville, NC, USA) in colorectal surgery. METHODS: We performed a retrospective analysis of prospectively collected data of patients who underwent colorectal surgery using the Senhance® robotic systems, from November 2018 to November 2020. Perioperative, intraoperative, and short-term postoperative data were assessed. RESULTS: There were 57 patients (28 women and 29 men, mean age 61.7 ± 6.2 years [range 23-84 years]). Forty-eight (84.2%) patients underwent surgery for colorectal cancer (22 colon cancer and 26 rectal cancer) and 9 (15.8%) for benign conditions. Mean operating time was 194 min ± 57.8 min (range 90-380 min). In total, 27(47.4%) operations were performed on the colon and 30 (52.6%) on the rectum; mean length of postoperative hospital stay was 8 ± 6.2 days (range 3-48 days). There were 2 (3.4%) conversions to open surgery. No intraoperative complications occurred. Seven patients (12.3%) had postoperative complications 3 (5.3%) of whom had to be treated under general anesthesia. There was no mortality. In 48 patients operated on for colorectal cancer, the mean lymph-node harvest was 18 ± 7.9 (range 7-38 lymph nodes). In the rectal cancer group of 26 patients, the distal resection margin was 3.3 ± 1.8 cm. CONCLUSIONS: In our experience, surgery using the new Senhance® robotic system was safe and feasible in surgery of the colon and rectum. Randomized controlled trials comparing this type of colorectal surgery with laparoscopic and/or other types of robotic surgery are needed.

PURPOSE: The purpose of this article was to provide feasibility and safety results of robotic transabdominal preperitoneal inguinal hernia repair (Robotic TAPP). METHODS: We included 271 cases of robotic inguinal hernia TAPP repair using the Senhance® robotic platform from four different centers between March 2017 and March 2020. Key data points were intraoperative and postoperative complication rate, operating time, length of hospital stay, postoperative pain score and time required to get back to a daily routine that were inserted in the TransEnterix European Patient Registry for Robotic assisted Laparoscopic Procedures in Urology, Abdominal Surgery, Thoracic and Gynecologic Surgery (TRUST). RESULTS: We report 203 cases of unilateral and 68 cases of bilateral inguinal hernia repairs. Mean operative time was 74 ± 35 min (range 32-265 min), postoperative complications occurred in five (1.85%) cases, the intraoperative complication rate was five (1.85%). The average subjective patient-related pain score after the procedure was 3 ± 1.9 (range 1-9), length of hospital stay was 39 ± 28 h (range 4-288 h), and recovery time was 9.65 ± 8 days (range 1-36 days). CONCLUSION: Robotic inguinal hernia TAPP repair shows inspiring results. It is a safe and doable procedure. However, cost analysis should be performed in future to show the superiority over other techniques.

BACKGROUND: Pancreatic infiltration by leucocytes represents a hallmark in acute pancreatitis. Although leucocytes play an active role in the pathophysiology of this disease, the relation between leucocyte activation, microvascular injury and haemorrhage has not been adequately addressed. METHODS: We investigated intrapancreatic leucocyte migration, leucocyte extravasation and pancreatic microperfusion in different models of oedematous and necrotising acute pancreatitis in lys-EGFP-ki mice using fluorescent imaging and time-lapse intravital microscopy. RESULTS: In contrast to the current paradigm of leucocyte recruitment, the initial event of leucocyte activation in acute pancreatitis was represented through a dose- and time-dependent occlusion of pancreatic capillaries by intraluminally migrating leucocytes. Intracapillary leucocyte accumulation (ILA) resulted in dense filling of almost all capillaries close to the area of inflammation and preceded transvenular leucocyte extravasation. ILA was also initiated by isolated exposure of the pancreas to interleukin 8 or fMLP, demonstrating the causal role of chemotactic stimuli in the induction of ILA. The onset of intracapillary leucocyte accumulation was strongly inhibited in LFA-1(-/-) and ICAM-1(-/-) mice, but not in Mac-1(-/-) mice. Moreover, prevention of intracapillary leucocyte accumulation led to the development of massive capillary haemorrhages and transformed mild pancreatitis into lethal haemorrhagic disease. CONCLUSIONS: ILA represents a novel protective and potentially lifesaving mechanism of haemostasis in acute pancreatitis. This process depends on expression of LFA-1 and ICAM-1 and precedes the classical steps of the leucocyte recruitment cascade.

The aim of this study was to compare the effect of different kinds of surgical meshes on postoperative adhesion formation. Forty-two New Zealand White rabbits were studied. The rabbits were grouped into six groups, according to the type of surgical meshes (Prolene, Mersilene, Vypro, polytetraflouroethylene (PTFE), Proceed and control group) implanted into the peritoneum cavity. Thirty days after the operation, the relaparotomies were carried out, and any adhesions observed between the implanted mesh and tissues were evaluated and graded. The mean adhesion degree was 9.2 in the Mersilene mesh group, 9.5 in the Prolene mesh group, 9.7 and in the Vypro mesh group (P > 0.05). The mean adhesion degree was 1 in the control group, 2.75 in the Proceed mesh group and 2.25 in the PTFE mesh group. There was a significant difference in adhesion degree between the control, Proceed and PTFE groups and the Prolene, Mersilene and Vypro mesh groups. The adhesion degree was significantly lower in the Proceed and PTFE mesh groups when comparing them with the Prolene, Mersilene and Vypro meshes.
