A resected lung weight ≥1.5 g was only significant risk factor of POBN in patients with PSP.

and O group (≥25 years, 40 sites). We used the inverse-probability of treatment weighted (IPTW) method to adjust for the heterogeneity in their backgrounds. POBN was diagnosed by computed tomography. Results: Cox regression analysis for the O group indicated that LW ≥3.0 g was a significant risk factor for POBN (P=0.049). For the Y group, no association between lung weight and POBN was observed. Conclusions: A LW ≥3.0 g is a significant risk factor for POBN in individuals aged ≥25 years.

The surgical results of mPulLE in patients with PSP with multiple lesions were equivalent to those achieved with three-port VATS under the same conditions.

We reported the feasibility of single-incision thoracoscopic surgery bullectomy using a chest wall pulley for lung excision (PulLE) in patients with primary spontaneous pneumothorax (PSP). PulLE has many merits including comfort of manipulation, cosmetic advantages, etc., compared to other procedures. However, our method was utilized for relatively straightforward cases. The PulLE was contraindicated for PSPs with multiple or comprehensive bullae. Therefore, we developed the modified PulLE (mPulLE) to treat such cases in February 2015. Although one chest wall pulley is placed in the thoracic cavity for a PulLE, two are used for an mPulLE. Herein, we describe the mPulLE technique.

Background: Omentoplasty is sometimes used to prevent perineal wound complications after abdominoperineal resection (APR) following neoadjuvant chemoradiotherapy (NACRT). However, recent studies have raised some controversy about its clinical benefit. Patients and Methods: Outcomes for rectal cancer patients who received APR after NACRT were retrospectively compared between the groups with omentoplasty (n=28) and without omentoplasty (n=14). Results: The operative time was significantly longer in the omentoplasty group (575 vs. 404 min, p<0.001). Laparoscopic surgery was performed more frequently in the omentoplasty group. Perineal wound problems including dehiscence and infection were significantly reduced in the omentoplasty group (46.4% vs. 78.6%, p<0.001). Univariate and multivariate analyses revealed that omentoplasty was the most important factor in reducing perineal wound complications (odds ratio=0.020, 95% confidence intervaI=0.001-0.393; p=0.001). Conclusion: Omentoplasty was useful in reducing perineal wound complications after APR following NACRT.Although abdominoperineal resection (APR) after neoadjuvant chemoradiotherapy (NACRT) for rectal cancer is a standard treatment strategy (1), postoperative perineal complications, such as wound infection, abscess, and wound dehiscence, Patients and MethodsPatient selection.
