ABSTRACT
Com o objetivo de promover, por meio de acesso único e com o uso de endoscópio flexível, ampla exploração da cavidade peritoneal de equinos em estação, foi concebida uma cânula laparoscópica para dar sustentação ao endoscópio e possibilitar o acesso sob visualização. O procedimento foi realizado a partir da fossa paralombar. Após pequena incisão cutânea, o endoscópio foi inserido na cânula e os músculos e o peritônio foram divulsionados mediante rotação da cânula. Logo depois da perfuração do peritônio, foi realizada a exploração da cavidade e a identificação das estruturas. Em seguida à exploração do lado ipsilateral ao acesso, realizou-se a transposição do conjunto cânula/endoscópio ventralmente à porção caudal do cólon descendente, seguida de exploração do lado contralateral. Concluída a técnica, foi executado, para fins de comparação, o mesmo procedimento por meio da fossa paralombar contralateral. Foi possível a transposição do conjunto cânula/endoscópio para o lado contralateral ao acesso em todos os procedimentos. Também foi possível a identificação da maioria das estruturas abdominais tanto pelo acesso esquerdo quanto pelo direito. A abordagem por acesso único mostrou-se viável para a exploração ampla da cavidade peritoneal, demonstrando ser uma alternativa à técnica laparoscópica convencional.(AU)
A laparoscopic cannula was designed to support a single access approach with a flexible endoscope for the wide exploration of the peritoneal cavity of standing horses. It provides support to the endoscope and allows access to the peritoneal cavity with a visual aid. This procedure was performed through the paralumbar fossa. After a small cutaneous incision, the endoscope was inserted into the cannula, and the muscles and peritoneum were divulsed through the rotation of the cannula. After the peritoneal perforation, cavity exploration and identification of structures were performed. After the exploration of the ipsilateral side of the access, the cannula/endoscope was transposed ventrally to the caudal portion of the descending colon; this was followed by the exploration of the contralateral side. Once this process was completed, the same procedure was performed through the contralateral paralumbar fossa for comparison. It was possible to transpose the cannula/endoscope set to the contralateral access side in all procedures. Further, it was possible to identify most of the abdominal structures in both the left and right access. This single access approach proved to be feasible for the extensive exploration of the peritoneal cavity, thereby indicating it can be an alternative to the conventional laparoscopic technique.(AU)

Objective@#To evaluate the safety, feasibility and operational effectiveness of master-slave system controlled Robot-assisted flexible endoscopy 'YunSRobot’ in upper gastrointestinal endoscopy examination in living pigs. @*Methods@#Seven Guangxi BA-MA Mini-pigs underwent upper gastrointestinal endoscopy examination with master-slave system controlled Robot-assisted flexible endoscopy 'YunSRobot’ and Olympus GIF-Q260J gastroendoscope (Japan). The experiment divided into manual operation group and robot operation group. Nine gastroenterologists skilled with endoscopy operation handled the robot once in vitro to familiar with the mechanism and method of robot operation. And then performed manual operation and robot operation four times each. Endoscopy pictures and operation time were recorded. T test and one-way analysis of variance were performed for statistical analysis. @*Results@#Both manual operation and robot operation could successfully finish standard esophagus and stomach endoscopic examination. There were no complications such as hemorrhage, perforation, mistaken insertion into of trachea, injures of pharynx and larynx and inhalation pneumonia. Esophagus, gastric cardia, gastric fundus, gastric body, gastric angle, gastric antrum and gastric pylorus could be clearly observed in both groups. The manual operating time of nine gastroenterologists was (3.67±1.95) minutes, which was shorter than that of robot operating time ((7.60±2.00) minutes), and the difference was statistically significant (t=8.445, P<0.01). The time of first in vitro operation performed by nine gastroenterologist was (13.10±6.32) minutes. The operation times of each case of nine gastrienterologist were (8.49±0.90) minutes, (7.50±1.19) minutes, (7.30±1.33) minutes and (7.12±1.61) minutes. The difference was statistically significant (F=7.901, P<0.01). Operation time gradually shortened and operation proficiency significantly improved. @*Conclusion@#Master-slave system controlled Robot-assisted flexible endoscopy 'YunSRobot’ which provides a clear observation of esophagus and stomach is safe in endoscopic examination of living animal.
ABSTRACT

ABSTRACT
Objective:To observe the clinical application of flexible endoscope assisted by general versus pillow-under-shoulder supine position in nasotracheal intubation of the patients with difficult airway, and to explore the influence of intubation position in the intubation effect.Methods: A total of 168 patients with difficult airway who underwent nasotracheal intubation and oromaxillofacial surgery under general anesthesia were randomly divided into general supine position (control group) and pillow-under-shoulder supine position (experimental group) with 84 cases in each group.The first-time and the total success rate of intubation, the intubation time, and the rate of direct glottis exposure of the patients in two groups were recorded.The mean arterial pressure(MAP), heart rate (HR), and complications of intubation of the patients in two groups before induction, before tracheal intubation, during intubation, 1 and 5 min after intubation, were also recorded.Results:The first-time success rate of intubation in experimental group (94.0 %, 79/84) was significantly higher than that in control group (71.4%, 60/84) (P0.05);the intubation time (57 s±12 s) was significantly shorter than that in control group (146 s±29 s) (P0.05).There were no significant differences in the MAP and HR between different time points (P>0.05).The incidence rates of complications including pharyngalgia, hoarseness and epistaxis had no differences between two groups (P>0.05).Conclusion: Flexible endoscope assisted by pillow-under-shoulder in nasotracheal intubation has a higher intubation success rate, shorter intubation time and it is a superior procedure for the patients with difficult airway.
ABSTRACT
Sinus is a cavity within a bone. Most are commonly found in the bones of the face. Specially, paranasal sinuses are air cavities in the cranial bones, especially those near the nose. They include the frontal sinuses, the ethmoid sinuses, the sphenoid sinuses and the maxillary sinuses. There are many types of sinus disease. They are classified as acute (quick onset) and chronic (over a long period of time). Besides, there are several other types of sinus diseases due to fungus and polyps. Sinus tumors also happen although it is relatively uncommon. Navigation software for general sinus surgery has been developed and are being used in the operation room. However, there are still many blind regions in the sinus area by using conventional straight type endoscope and devices. To cope with such a problem, flexible endoscope and devices are being developed along with advanced navigation algorithms. In this review, many research activities associated with computer-aided sinus surgery are discussed.

@#BACKGROUND: The study aimed to estimate the value of embryonal natural orifice transluminal endoscopic surgery (ENOTES) in treating severe acute pancreatitis (SAP) complicated with abdominal compartment syndrome (ACS). METHODS: The patients, who were randomized into an ENOTES group and an operative group, underwent ENOTES and laparotomy, respectively. The results and complications of the two groups were compared. RESULTS: Enterocinesia was observed earlier in the ENOTES group than in the operative group. Acute Physiology and Chronic Health Evaluation II (APACHE II) score of patients in the ENOTES group was lower than that of the operative group on the 1st, 3rd and 5th post-operative day (P<0.05). The cure rate was 96.87％ in the ENOTES group, which was statistically different from 78.12％ in the operative group (P<0.05). There were significant differences in complications and mortality between the two groups (P<0.01). CONCLUSION: Compared with surgical decompression, ENOTES associated with flexible endoscope therapy is an effective and minimal invasive procedure with less complications.

ABSTRACT
PURPOSE: There have been a few data about esophageal length in children and previous data are improper for application to various procedures. Because of the variability in height and weight of each the individuals especially in children, measurable external parameters are needed. METHODS: We measured distance from upper incisor to esophago-gastric junction using a flexible endoscope and compared these data with age, height and weight in 262 children who underwent upper gastrointestinal endoscopy. RESULTS: The mean age was 9.0+/-3.6 year (from 2 days to 16 year of age), mean height was 132.89+/-23.49 cm and mean length from upper incisor to esophago-gastric junction was 33.34+/-5.42 cm. Correlation between distance from upper incisor to esophago-gastric junction and height was the mostly predictable indicator of the esophageal length (Pearson correlation=0.944). We propose a formula [Esophageal length=4.419+(0.218 x height)] as a indicator of the esophageal length (p=0.000, R2=0.891). CONCLUSION: The esophageal length in children and for application to various procedures can be reliably predicted by using the height.
