Buddhist culture places a high priority on the eyes. The restoration of light through the treatment of eye conditions represents the dispelling of the illusion of the transmigratory worlds and the attainment of enlightenment. The treatment of eye disorders was a difficult medical issue that involved numerous prescriptions, procedures, and mantras in the Tang Dynasty medicine. It was not simply a metaphor for wisdom. The narrative of Bai Juyi’s 白居易 (772–846) fighting against eye diseases highlights the value of the golden scalpel technique (jinbi shu 金篦術) and medical texts attributed to Ngârjuna Bodhisattva (Longshu 龍樹), which profoundly affected Chinese medicine on treating the eyes throughout the Tang Dynasty. Furthermore, the tale of Li Shangyin’s 李商隱 (813–858) eyes being treated by Zhixuan 知玄 can only be fully explored within the context of the Esoteric Buddhism, where mandalas, prescriptions, rituals, and dhāraṇīs are frequently used in conjunction with eye care. The case of Qin Minghe 秦鳴鶴, however, suggests that ophthalmology practiced by Buddhists may become more popular as a result of religious competition. Full article

This study aimed to evaluate the sealing quality of swine small intestine using different laparoscopic radiofrequency vessel sealing devices (two 5 mm: RFVS-1 and -2; one 10 mm: RFVS-3) and a harmonic scalpel (HS) compared to golden standard closure technique. The study was divided into two arms. In study arm 1: n = 50 swine intestinal loops (10 per group) were transected with each instrument and the loops in which the devices provided complete sealing, at the gross inspection, were tested for maximum burst pressure (BP) and histological evaluation and compared to an automatic linear stapler. After the BP tests, the devices that achieved significantly lower BP values were excluded from the second arm. The RFVS-1 and -3 provided statistically significant results and were used in study arm 2, to obtain full-thickness biopsies along the antimesenteric border of the loop and were compared with hand-sewn intestinal closure (n = 30; 10 per group). The biopsies were histologically evaluated for thermal injury and diagnostic features, and intestinal loops tested for BP. RFVS-3 achieved comparable results (69.78 ± 4.23 mmHg, interquartile range (IQR) 5.8) to stapler closing technique (71.09 ± 4.22 mmHg, IQR 4.38; p > 0.05), while the RFVS-1 resulted in significantly (p < 0.05) lower BP (45.28 ± 15.23 mmHg, IQR 24.95) but over the physiological range, conversely to RFVS-2 (20.16 ± 7.19 mmHg, IQR 12.02) and HS (not measurable). RFVS-3 resulted not significantly different (p > 0.05) (45.09 ± 8.75 mmHg, IQR 10.48) than Suture (35.71 ± 17.51 mmHg, IQR 23.77); RFVS-1 resulted significantly lower values (23.96 ± 10.63 mmHg, IQR 9.62; p < 0.05). All biopsies were judged diagnostic. Data confirmed that RFVS-1 and -3 devices provided suitable intestinal sealing, with BP pressures over the physiological range. Conversely, the HS and RFVS-2 should not be considered for intestinal sealing. RFVS devices could be employed to obtain small intestine stump closure or full-thickness biopsies. However, further studies should be performed in live animals to assess the role of the healing process. Full article
