Background: The management of the intersegmental plane (ISP) is challenging during uniport videoassisted thoracoscopic (VATS) pulmonary segmentectomy. Staplers and electrocautery have been used extensively in ISP management. However, both of them have their respective drawbacks. Currently, we have provided a revised technique termed as "Combined Dimensional Reduction Method" (CDR method), for managing the ISP with combined application of ultrasonic scalpel and staplers. The study aimed to review the outcomes of patients who underwent uniport VATS segmentectomy with or without the CDR method in our institute and assess the feasibility and safety of the CDR method.Methods: From March 2017 to February 2018, 220 patients who underwent uniport VATS segmentectomy were retrospectively reviewed. By using IQQA software, pulmonary structures were reconstructed as three-dimensional (3D) images, making the targeted structures could be identified preoperatively. For the management of the ISP, in the CDR group, we firstly used the ultrasonic scalpel to trim the 3D pulmonary structure along the intersegmental demarcation, making the remaining targeted parenchyma both sufficiently thin enough and located on a 2D plane; thus, enabling easy use of staplers in managing ISP. Whereas, in the non-CDR group, we only use the staplers to manage the ISPs. The clinical characteristics, complications, and postoperative pulmonary functions were compared between the two groups.Results: Propensity score analysis generated 2 well-matched pairs of 71 patients in CDR and non-CDR groups. There was no 30-day postoperative death or readmission in either group. The CDR group was significantly associated with the shorter operative time (178.3±35.8 vs. 209.2±28.7 min) (P=0.031) and postoperative stay (4.5±2.3 vs. 5.7±4.2 days) (P=0.041), compared to the non-CDR group. Moreover, no significant difference was observed in blood loss, a period of chest tube drainage, a period of ultrafine tube drainage, and postoperative pulmonary complications between the two groups. Moreover, the recovery rate of postoperative forced expiratory volume in 1 second (FEV1) or vital capacity (VC) at 1 and 3 months after segmentectomy was comparable between them. Conclusions:The CDR method could make segmentectomy easier and more accurate, and therefore has the potential to be a viable and effective technique for uniport VATS pulmonary segmentectomy.
Introduction Subxiphoid uniportal video-assisted thoracoscopic surgery (VATS) has been gradually applied for the treatment of anterior mediastinal tumour (AMT). However, whether obesity is a risk factor for subxiphoid uniportal VATS for AMT is still unknown. Aim To explore the safety and short-term outcome of subxiphoid uniportal VATS for AMT in obese patients. Material and methods The clinical data of 142 patients who received VATS via subxiphoid approach for AMT were analysed. According to body mass index (BMI), the patients were divided into an obese group (BMI ≥ 28 kg/m 2 ) and a non-obese group (BMI < 28 kg/m 2 ). Then, the clinical and surgical characteristics between the obese group and the non-obese group were analysed to explore the effect of obesity on VATS for AMT. The pain scores were evaluated by the Numeric Rating Scale. Results The operative time and tracheal intubation time using subxiphoid uniportal VATS for AMT in the obese group were longer than that in the non-obese group (p < 0.05). However, there was no obvious difference in intraoperative blood loss, chest tube drainage time, chest tube drainage volume, and length of hospital stay between the obese group and the non-obese group (p > 0.05). Moreover, there was also no significant difference in postoperative complications, including pulmonary complications, wound infection, arrhythmia, and pulmonary leak, between the obese group and the non-obese group. In addition, the pain scores in the obese group were similar to those in the non-obese group. Conclusions Although obesity might prolong operative time of subxiphoid uniportal VAST for AMT, it does not increase the rate of postoperative complications. An experienced centre can properly conduct VAST via subxiphoid approach when treating AMT in obese patients.
A 27-year-old man presented with intermittent right knee pain for 1 year with no previous trauma. Physical examination revealed only tenderness over the patella. Typical fluid–fluid levels were visible on magnetic resonance imaging (MRI), which highly suggested aneurysmal bone cyst (ABC) of the patella. After removal of a large window of thin cortical bone, curettage and bone grafting followed by cerclage wiring was performed. Histology confirmed the initial diagnosis of primary ABC of the patella. At the final follow-up visit at 71 months after surgery, the patient had normal joint activity with no pain or evidence of recurrence. Previous publications indicated patellectomy in the initial series, but curettage and bone grafting have more recently provided excellent results and good graft incorporation in most cases, even for aggressive lesions. In our patient, thorough curettage and bone grafting through a wide cortical window followed by cerclage wiring fixation and figure-eight sutures was a successful treatment option for primary ABC of the patella without articular disruption.
