Does a gender have something to do with clinical pictures of primary spontaneous pneumothorax?

Objective: Primary spontaneous pneumothorax is relatively rarer in women than in men. In addition, women develop secondary spontaneous pneumothorax, such as lymphangioleiomyomatosis, which is rare and difficult to diagnose. Therefore, the clinical characteristics of primary spontaneous pneumothorax in women remain unknown presently.

Contralateral bulla neogenesis associated with postoperative recurrences of primary spontaneous pneumothorax in young patients.

Background: Video-assisted thoracoscopic surgery (VATS) is considered an acceptable treatment for recurrent primary spontaneous pneumothorax (PSP). However, recent reports have described a high postoperative recurrence rate in young patients with PSP. We hypothesized that ineffective VATS may have been performed for these patients (aged <25 years).

Optimal margin distance of bullectomy for primary spontaneous pneumothorax reduces postoperative recurrence.

Background: For primary spontaneous pneumothorax, bullectomy using autosutures is the standard procedure. Despite performing various methods for preventing postoperative recurrence, it remains relatively high. Although considering the margin distance of bullectomy is important, no argument has been discussed for the optical margin distance until now.

The clinical characteristics and surgical results of smoking-related young pneumothorax.

Objective: Primary spontaneous pneumothorax is a common disease that develops in relatively young healthy patients. Although smoking is generally believed to have a negative effect on the lungs, some authors reported that smokers with primary spontaneous pneumothorax had significantly lower postoperative recurrence rates than nonsmokers. This unexpected result suggests that primary spontaneous pneumothorax is classified into two categories: smoking-related young pneumothorax and residual primary spontaneous pneumothorax.

Natural history of bulla neogenesis for primary spontaneous pneumothorax: a propensity score analysis.

Objective: For patients with recurrent primary spontaneous pneumothorax, surgery has been thought to be an acceptable treatment. However, even if bulla is completely resected, postoperative recurrence is relatively common due to bulla neogenesis. Bulla neogenesis seems to develop naturally in younger patients compared with the elderly, as theorized till date.

Pleural Coating by 50% Glucose Solution Reduces Postoperative Recurrence of Spontaneous Pneumothorax.

Background: Video-assisted thoracoscopic surgery is the standard procedure for treatment of spontaneous pneumothorax. However, postoperative recurrence is relatively common even if an absorbable covering sheet is used for reinforcement of the visceral pleura. Injection of a high concentration glucose solution to the thoracic cavity was recently reported to be effective in stopping postoperative air leakage or as a prophylactic procedure to prevent postoperative recurrence of spontaneous pneumothorax.

[Injection of High Concentration Glucose Solution for Pleural Coating Reduces Postoperative Recurrence of Spontaneous Pneumothorax;A Short-term Retrospective Study].

Background: Video-assisted thoracoscopic surgery (VATS) is the standard treatment for patients with spontaneous pneumothorax (SP). However, postoperative recurrence is not infrequent even with an absorbable covering sheet used to reinforce the visceral pleura. Recent reports suggest that intraoperative injection of a highly concentrated glucose solution into the thoracic cavity provides effective prophylaxis against postoperative SP recurrence.

Feasibility of single-incision thoracoscopic surgery using a modified chest wall pulley for primary spontaneous pneumothorax: a propensity score matching analysis.

Purpose: Recently, single-incision thoracoscopic surgery (SITS) has been recognized as a favorable treatment choice for primary spontaneous pneumothorax (PSP) compared with conventional three-port video-assisted thoracoscopic surgery (VATS). However, conventional SITS bullectomy often results in collisions with surgical devices. Therefore, we devised a method of SITS using a chest wall pulley for lung excision (PulLE) and modified PulLE (mPulLE) system, which substitutes threads to eliminate such collisions.

Association between postoperative bulla neogenesis at the staple line and resected lung weight for primary spontaneous pneumothorax: a retrospective study using the inverse-probability of treatment weighted method in patients grouped according to age.

Background: Bullectomy using autosutures is the standard procedure in patients with primary spontaneous pneumothorax (PSP). However, postoperative bulla neogenesis (POBN) along the staple line is relatively common and promotes PSP recurrence. We have previously reported the relationship between POBN and resected lung weight (LW).

Modified Chest Wall Pulley for Lung Excision during Single-Incision Thoracoscopic Surgery for Primary Spontaneous Pneumothorax.

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.

[Propensity-score-matched Comparison of Postoperative Pain Between Young and Elderly Patients Who Underwent Video-assisted Thoracoscopic Surgery for Spontaneous Pneumothorax].

Video-assisted thoracoscopic surgery (VATS) is the standard treatment for spontaneous pneumothorax(SP). Although VATS has decreased the postoperative pain in comparison with conventional thoracotomy, the procedure still often requires sufficient postoperative pain management especially for young patients, and the present study on the postoperative pain management focused on the age difference was designed. Using the numerical rating scale, we compared postoperative pain between the young group(36 patients) and the elderly group (36 patients) selected by propensity score matching in order to adjust for the patients' backgrounds.

Novel paravertebral block during single-incision thoracoscopic surgery for primary spontaneous pneumothorax.

Recently, the use of paravertebral block (PVB) during thoracic surgery has been re-evaluated, as it is not inferior to epidural anaesthesia for postoperative pain control, and has been associated with fewer complications (e.g., hematoma of epidural, hypotension, urinary retention, postoperative nausea and vomiting).

Relationship between postoperative bulla neogenesis at the staple line and the resected lung volume in primary spontaneous pneumothorax.

Purpose: In patients with primary spontaneous pneumothorax (PSP), bullae are generally resected using autosutures under video-assisted thoracoscopic surgery (VATS). However, postoperative bulla neogenesis (POBN) along the staple line is not rare and is a factor promoting PSP recurrence. POBN is attributed to tension along the staple line, and we surmise that the resected lung volume affects this tension.

Single-incision thoracoscopic surgery using a chest wall pulley for lung excision in patients with primary spontaneous pneumothorax.

Purpose: The aim of the study was to evaluate the feasibility and compare the outcomes of single-incision thoracoscopic surgery using a chest wall pulley for lung excision (PulLE) vs. those of conventional video-assisted thoracic surgery (cVATS) in patients with primary spontaneous pneumothorax (PSP).

Methods: Sixty-nine patients who underwent PulLE (n = 34) or cVATS (n = 35) between January 2009 and December 2013 were enrolled in this study.

[Evaluation of 2 ports video-assisted thoracoscopic surgery (VATS) using endo-close for primary spontaneous pneumothorax].

We aimed to assess the perioperative outcomes of 2 ports video-assisted thoracoscopic surgery(VATS) using Endo-Close (2 ports VATS) in patient for the primary spontaneous pneumothorax(PSP) compared to conventional 3 ports VATS in our hospital. 31 consecutive patients(11;2 ports VATS and 20;3 ports VATS) since 2009 were enrolled in this study. Endo-Close is a device that for pulling the anchoring thread by puncture 1.

[Pleuroperitoneal communication with liver cirrhosis and chronic kidney disease needed hemodialysis successfully treated by video-assisted thoracoscopic surgery; report of a case].

A 59-year-old man treated with hemodialysis for liver cirhhosis and chronic kidney disease developed right pleural effusion and ascites. Ascites always decreased after thoracocentesis for pleural effusion. In spite of repeated treatment with chest tube drainage, massive pleural effusion reappeared.
