Trans-bronchoscopy with implantation of 125I radioactive seeds in patients with pulmonary atelectasis induced by lung cancer

Abstract Objective The aim of this study was to explore the safe and effective method of expectoration in the preoperative period of patients with lung cancer resection and to promote the rehabilitation of patients. Methods A total of 100 cases of lung cancer patients undergoing elective surgery were divided into the observation group and the control group, with 50 cases in each group. The control group was treated with vibration expectoration vest for expectoration during the perioperative period, and the observation group was treated with respiratory function exerciser that has expectoration function in the perioperative period, three times a day, and the effect was evaluated after 5 days. Results The number of patients in the observation group after the first expectoration time was significantly less than that of the control group (P<0.001). Pain score, pulmonary atelectasis, and pulmonary infection rate of the observation group were significantly lower than those of the control group; the hospitalization time was significantly shorter than that of the control group; and the difference was statistically significant (P<0.05). Conclusions Lobectomy for lung cancer patients with perioperative respiratory training for respiratory function exercise, compared with conventional methods, is helpful for postoperative expectoration and to reduce the incidence of adverse events.

Abstract To transfer the preplan for the head and neck brachytherapy to the clinical implantation procedure, a preplan-based 3D-printed individual template for needle insertion guidance had previously been designed and used. The accuracy of needle insertion using this kind template was assessed in vivo. In the study, 25 patients with head and neck tumors were implanted with 125I radioactive seeds under the guidance of the 3D-printed individual template. Patients were divided into four groups based on the site of needle insertion: the parotid and masseter region group (nine patients); the maxillary and paranasal region group (eight patients); the submandibular and upper neck area group (five patients); and the retromandibular region group (six patients). The distance and angular deviations between the preplanned and placed needles were compared, and the complications and time required for needle insertion were assessed. The mean entrance point distance deviation for all 619 needles was 1.18 ± 0.81 mm, varying from 0.857 ± 0.545 to 1.930 ± 0.843 mm at different sites. The mean angular deviation was 2.08 ± 1.07 degrees, varying from 1.85 ± 0.93 to 2.73 ± 1.18 degrees at different sites. All needles were manually inserted to their preplanned positions in a single attempt, and the mean time to insert one needle was 7.5 s. No anatomical complications related to inaccurately placed implants were observed. Using the 3D-printed individual template for the implantation of 125I radioactive seeds in the head and neck region can accurately transfer a CT-based preplan to the brachytherapy needle insertion procedure. Moreover, the addition of individual template guidance can reduce the time required for implantation and minimize the damage to normal tissues.
