Article Abstract
Objective: Our aim was to develop an insufflation system for CT colonography enabling even and quick air inflation as well as pressure control and optional emergency decompression.
Patients And Methods: A modified air insufflation system for CT colonography, consisting of an electric air pump, manometer, safety valve, and a balloon tip is presented. Thirty one patients underwent CT colonography from August to December, 2004.
Results: Optimal distension was achieved in 30 patients; the distension was incomplete (partial) only in one case. The insufflation was performed within 60 seconds in 28 of the cases, in 2 patients--within 180 seconds and in one patient--after 180 seconds.
Conclusions: The presented insufflation system allows optimization of CT colonography technique, reduces the risk of adverse events during examination and improves the precision of the method.

Introduction: Complex gastroschisis requires timely intervention to protect the fetal intestine from inflammation and strangulation and avoid viscero-abdominal disproportion (VAD). Earlier results in ovine models for the fetoscopic management of gastroschisis highlight the benefits of minimally invasive coverage; yet specialized instruments appear to be needed for better procedural execution. The aim of this study was to create and validate a first prototype instrument for the prenatal covering of the protruded intestines in gastroschisis.

Background: Gel immersion endoscopy is a novel method that uses gel to enhance the visual field. This study aimed to analyze the efficacy of magnified endoscopy under gel immersion for optimal visualization and characterization of colorectal tumors.
Methods: We retrospectively examined 107 lesions observed with blue-laser/light imaging (BLI) or narrow-band imaging (NBI) between June 2022 and July 2023 using the Japan NBI Expert Team classification.

Background: Robot-assisted breast-conserving surgery has a potentially better cosmetic benefit than conventional breast-conserving surgery without any scarring on the breast. However, data on the feasibility and safety are limited. This study presents the results of early robot-assisted breast-conserving surgery.

Patients with severe emphysematous bullae present significant anesthetic challenges, especially during laparoscopic or robotic-assisted surgeries, where positive pressure ventilation and pneumoperitoneum increase the risk of barotrauma. Rupture of a bulla can cause life-threatening tension pneumothorax, and intervention may be delayed in robotic cases due to limited access. A 62-year-old male patient with chronic obstructive pulmonary disease (COPD) and extensive bilateral bullous disease was scheduled for robotic-assisted laparoscopic inguinal hernia repair.

Objective: Surgical procedures in small cetaceans are rarely considered as treatment options due to anatomic considerations limiting exposure, concerns with achieving a watertight incisional closure, and logistical complexities of both anesthesia and surgery in completely aquatic mammals. The objective is to provide a video tutorial on laparoscopic-guided abdominal approaches with the goal to expand diagnostic and treatment capabilities for common diseases in these species.
Animals: Small cetaceans undergoing laparoscopy for diagnostic or therapeutic purposes.
