Lay Summary To prevent intraoperative organ injury, surgeons strive to identify anatomical structures as early and accurately possible during surgery. The objective of this prospective observational study was develop artificial intelligence (AI)-based real-time automatic recognition models in laparoscopic surgery compare its performance with that surgeons. time taken recognize target anatomy between AI both expert novice compared. demonstrated faster than surgeons, especially These findings...
Conversion to laparotomy is among the serious intraoperative complications and carries an increased risk of postoperative complications. In this cohort study, we investigated whether or not Endoscopic Surgical Skill Qualification System (ESSQS) affects conversion rate patients undergoing laparoscopic surgery for rectal cancer.
Epoxy-silicate nanocomposites were prepared by dispersing synthetic layered silicates modified with alkylammonium ions. In the process, organically mixed in epoxy resin shearing, and aggregations of removed centrifugal separation after mixing silicates. Micrographs taken transmission electron microscopy (TEM) indicate that have a morphology including both parallel silicate layers (0.1-0.5 /spl mu/m, 5-15 layers) exfoliated (nano-scale dispersion) area. terms thermal resistance properties,...
The surge discharge capability and the thermal stability of a metal oxide arrester were examined experimentally.
A semi-analytical approach is proposed for potential distribution of metal-oxide surge arresters under normal condition. Conventional approaches like the finite-element method are also applicable. The authors suggest that more appropriate a general approach; an analysis in combination with lumped constants R, L and C possible. Environmental conditions pollution snow-covering on surface insulators may disturb at Potential distributions were experimentally measured artificial test, naturally...
Abstract Introduction Disadvantages of bowel perfusion assessment with indocyanine green fluorescence angiography include the need for a fluorophore and subjective nature assessment. This study was performed to evaluate clinical efficacy using laser speckle contrast imaging (LSCI) during laparoscopic colorectal surgery. Methods The population comprised first 27 consecutive patients who underwent left‐sided resection intraoperative LSCI. operative outcomes these were compared those matched...
Abstract A 43‐year‐old woman was diagnosed with a hydrocele of the canal Nuck, for which laparoscopic total extraperitoneal excision successfully undertaken. The located entirely within inguinal and barely visible at internal ring, even strong retraction. inferior epigastric vessels were risk injury secondary to excessive tension when retracting round ligament. To overcome these problems, approached from medial side across transversalis fascia. This approach allowed us reach distal end avoid...
The voltage-current, watt loss, and characteristics of three kinds ZnO elements were compared when subjected to ac dc voltages.
Colorectal metastases from primary colorectal cancers are very rare, and little is known about their epidemiological aspects or the best diagnostic therapeutic strategies. Herein, we report a case of 65-year-old woman with suspected metachronous metastasis to rectum transverse colon cancer.The patient underwent laparoscopic extended right hemicolectomy for cancer. Histopathological examination showed moderately differentiated adenocarcinoma, tumor was diagnosed as stage IIA (T3, N0, M0)....
Abstract We report a rare case of visceral injury after totally extraperitoneal endoscopic inguinal hernia repair. A 48‐year‐old man underwent needlescopic repair direct hernia. Bleeding from branch the inferior epigastric vessels occurred at beginning dissection with monopolar electrosurgical device. Hemostasis was prolonged. However, herniorrhaphy and mesh were successfully performed, no peritoneal disruption or pneumoperitoneum visible. The patient discharged home on next day. 30 h this...

It is found that the polarised quasi-elastic light scattering (QELS) in three investigated glasses, namely silica, o-terphenyl and ethanol, exhibits a step-wise increase of intensity when passing frequency longitudinal Brillouin line towards lower frequencies, keeping, however, same dependence as depolarised spectrum. The latter shows no such excess QELS. amplitude this QELS proportional to ratio integral intensities boson peak, while relaxation mechanisms are for both spectra. This we take...
