Diagnostic transgastric flexible peritoneoscopy: is pure natural orifice transluminal endoscopic surgery a fantasy?
We present the first transgastric peritoneoscopy in a 20-year-old man. The objectives were to evaluate the impact of the site of viscerotomy on the technical feasibility of natural orifice transluminal endoscopic surgery (NOTES), assess transgastric peritoneoscopy as a complementary procedure, determine the safety and efficacy of NOTES, and attempt inspection/biopsy of the gallbladder. The patient was admitted with a benign gastric outlet obstruction, chronic cholecystitis and radiological suspicion of a mass in the gallbladder which was not visualised on diagnostic laparoscopy. Complementary transgastric peritoneoscopy was performed to gain deeper penetration of the tumour with the flexible tip of the gastroscope. The visceral "aperture" was created in the antrum where gastrojejunal anastomosis would be fashioned. Laparoscopic transillumination of the anterior gastric wall facilitated this part of the procedure. During transgastric peritoneoscopy, the gallbladder and structures in the upper and left hemi-abdomen appeared retrograde due to the unusual location of the gastrotomy. The right hemi-abdomen and pelvis were easily examined with a "straight shaft" approach. The gallbladder could not be identified with exploratory laparoscopy and transgastric peritoneoscopy. Due to risk of visceral injury, open gastrojejunal anastomosis and cholecystectomy were performed. Intraoperatively, an inflamed, thick-walled gallbladder was found adherent to the proximal duodenum. Transgastric peritoneoscopy was safely performed in our patient. The postoperative course was uneventful. Our patient showed significant improvement at 13 weeks after surgery without any procedure-related complication. In conclusion, transgastric peritoneoscopy may be used to complement diagnostic laparoscopy. Laparoscopic assistance during transluminal access facilitates simple tasks inside the peritoneal cavity to be performed safely.
