Abstract
BACKGROUND AND AIMS On-demand insufflation during endoscopic peritoneoscopy causes wide variations in intra-abdominal pressure. Its effects on splanchnic microcirculation may differ from those of steady intra-abdominal pressure, because pressure characteristics affect crucial intravascular hemodynamic forces--pressure and shear--adapting flow to local metabolic needs. Our aim was to assess the effect of natural orifice transluminal endoscopic surgery (NOTES) peritoneoscopy on splanchnic microcirculatory blood flow. METHODS Twenty-one swine were randomized to the following: cholecystectomy by transgastric NOTES (n = 8), cholecystectomy by standard laparoscopy (Lap) (n = 8), and a sham group (n = 5). During NOTES, CO2 was manually insufflated with a maximum allowed pressure of 30 mm Hg. In the Lap group, intra-abdominal pressure was maintained at 14 mm Hg. Systemic hemodynamics were measured, and microcirculatory blood flow was quantified by using colored microspheres. RESULTS Mean intra-abdominal pressure was lower in NOTES than in the Lap group (P = .038). In both groups, cardiac index and preload remained unchanged, whereas systemic vascular resistances increased over time, with a lesser increase in the Lap group (2-way analysis of variance; P = .041). In pneumoperitoneum groups, microcirculatory blood flow decreased similarly in the renal medulla, stomach, small bowel, colon, and mesocolon by 30%, 45%, 34%, 32%, and 37%, respectively. In NOTES, there was a greater microcirculatory blood flow decrease in the renal cortex (NOTES 41% vs Lap 35%; P = .044) and mesentery (NOTES 44% vs Lap 38%; P = .041). CONCLUSIONS These findings suggest that both types of pneumoperitoneum have similar physiologic effects on microcirculatory blood flow. However, on-demand pneumoperitoneum (NOTES group) caused a greater microcirculatory blood flow decrease in areas with low metabolic needs, redistributing blood flow toward metabolically active areas.

Lu HY, Chu Y, Wu YC, Liu CY, Hsieh MJ, Chao YK, Wu CY, Yuan HC, Ko PJ, Liu YH, Liu HP. Hemodynamic and inflammatory responses following transumbilical and transthoracic lung wedge resection in a live canine model. Int J Surg 2015; 16:116-122. [PMID: 25769396 DOI: 10.1016/j.ijsu.2015.02.027] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2014] [Revised: 02/14/2015] [Accepted: 02/28/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND Single-port transumbilical surgery is a well-established platform for minimally invasive abdominal surgery. The aim of this study was to compare the hemodynamics and inflammatory response of a novel transumbilical technique with that of a conventional transthoracic technique in thoracic exploration and lung resection in a canine model. METHODS Sixteen dogs were randomly assigned to undergo transumbilical thoracoscopy (n = 8) or standard thoracoscopy (n = 8). Animals in the umbilical group received lung resection via a 3-cm transumbilical incision in combination with a 2.5-cm transdiaphragmatic incision. Animals in the standard thoracoscopy group underwent lung resection via a 3-cm thoracic incision. Hemodynamic parameters (e.g., mean arterial pressure, heart rate, cardiac index, systemic vascular resistance, and global end-diastolic volume index) and inflammatory parameters (e.g., neutrophil count, neutrophil 2',7' -dichlorohydrofluorescein [DCFH] expression, monocyte count, monocyte inducible nitric oxide synthase expression, total lymphocyte count, CD4+ and CD8+ lymphocyte counts, the CD4+/CD8+ratio, plasma Creactive protein level, interleukin-6 level) were evaluated before surgery, during the operation, and on postoperative days 1, 3, 7, and 14. RESULTS Lung resections were successfully performed in all 16 animals. There were 2 surgery-related mortality complications (1 animal in each group). In the transumbilical group, 1 death was caused by early extubation before the animal fully recovered from the anesthesia. In the thoracoscopic group, 1 death was caused by respiratory distress and the complication of sepsis at 5 days after surgery. There was no significant difference between the two techniques with regard to the hemodynamic and immunologic impact of the surgeries. CONCLUSION This study suggests that the hemodynamic and inflammatory changes with endoscopic lung resection performed by the transumbilical approach are comparable to those after using the conventional transthoracic approach. This information is novel and relevant for surgeons interested in developing new surgical techniques in minimally invasive surgery.

Gastric endoscopic submucosal dissection under steady pressure automatically controlled endoscopy (SPACE); a multicenter randomized preclinical trial. Surg Endosc 2014; 29:2748-55. [PMID: 25480619 DOI: 10.1007/s00464-014-4001-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2014] [Accepted: 11/09/2014] [Indexed: 01/29/2023]
Abstract
BACKGROUND Steady pressure automatically controlled endoscopy (SPACE) is a new modality that eliminates on-demand insufflation but enables automatic insufflation in the gastrointestinal tract. Though its use in porcine esophageal ESD was reported to be promising, its applicability and potential effectiveness to gastric procedures have not been evaluated. OBJECTIVE The aims were (1) to evaluate feasibility and safety of SPACE in the stomach, and (2) to assess its potential advantages over conventional endoscopy in preventing "blind insufflation"-related complications. DESIGN A multicenter randomized preclinical animal study. SETTING Laboratories at three universities. INTERVENTIONS Experiment 1: Gastric ESD was attempted in the swine (n = 17), under either SPACE or manual insufflation. Experiment 2: Gastroscopy was performed for 10 min in the perforated stomach (n = 10) under either SPACE or manual insufflation. MAIN OUTCOME MEASUREMENTS Experiment 1: ESD time, energy device activation time, number of forceps exchanges, specimen size, en block resection rate, vital signs and any intraoperative adverse events. Experiment 2: Intra-gastric and intra-abdominal pressures, vital signs, and any adverse events. RESULTS Experiment 1: Gastric ESD was completed in all animals. ESD time tended to be shorter in SPACE than in the control, though the difference was not significant (p = 0.18). Experiment 2: Although both intra-gastric and intra-abdominal pressures remained within preset values in SPACE, they showed excessive elevation in control. LIMITATIONS An animal study with small sample size. CONCLUSIONS SPACE is feasible and safe for complicated and lengthy procedures such as gastric ESD, and is potentially effective in preventing serious consequences related to excessive blind insufflation.

Abstract
Natural orifice transluminal endoscopic surgery (NOTES) is an evolving field of minimally invasive surgery. NOTES reaches the target organ by inserting the endoscope through a natural orifice (e.g. mouth, anus, urethra, vagina) and offers advantages of less postoperative pain and lower complication rate. Since its first description in 2004, NOTES has progressed from use on animal models to humans. We experienced anesthetic care of two patients who underwent transoral NOTES under general anesthesia.

Abstract
BACKGROUND Transesophageal natural-orifice transluminal endoscopic surgery (NOTES) mediastinoscopy has been described as a feasible, less-invasive alternative to video-assisted mediastinoscopy (VAM). We aimed to investigate hemodynamic and respiratory effects during transesophageal NOTES mediastinoscopy compared with VAM. PATIENTS AND METHODS This was a short-survival experiment in 20 female pigs randomized to NOTES (n = 10) or VAM (n = 10) mediastinoscopy. In the NOTES group, an endoscopist accessed the mediastinum through a 5-cm submucosal tunnel in the esophageal wall, and CO2 was used to create the pneumomediastinum. Conventional VAM was carried out by thoracic surgeons. A 30-minute systematic exploration of the mediastinum was then performed, including invasive monitoring for hemodynamic and respiratory data. Blood samples were drawn for gas analyses. RESULTS All experiments except 2 in the NOTES group (one because of technical difficulties, the other because of thoracic lymphatic duct lesion) were completed as planned, and animals survived 24 hours. Also, 3 animals in the NOTES group presented a tension pneumothorax that was immediately recognized and percutaneously drained. VAM and NOTES animals showed similar pulmonary and systemic hemodynamic behavior during mediastinoscopy. Pulmonary gas exchange pattern was mildly impaired during the NOTES procedure, showing lower partial arterial oxygen pressure associated with higher airway pressures (more important in animals that presented with pneumothorax). CONCLUSIONS NOTES mediastinoscopy induces minimal deleterious respiratory effects and hemodynamic changes similar to conventional cervical VAM and could be feasible when performed under strict hemodynamic and respiratory surveillance. Notably, serious complications caused by the injury of pleura are more frequent in NOTES, which mandates an improvement in technique and suitable equipment.
