Chemical pleurodesis with Viscum album L. extract for secondary spontaneous pneumothorax in elderly patients

Early Pleurodesis for Postoperative Air Leak with Autologous Blood and 50% Glucose Solution

Background

Postoperative air leaks after pulmonary resection prolong the duration of chest drainage and the length of hospital stay. One of the many treatment options is bedside pleurodesis using various agents. This study evaluated the feasibility of an early intervention to stop postoperative air leaks with either autologous blood or a 50% glucose solution.

Methods

We retrospectively reviewed 323 patients who underwent bedside pleurodesis between January 2017 and March 2022. Sixty-four patients received autologous blood patch pleurodesis, and 36 were treated with a 50% glucose solution after pulmonary resection. The primary endpoints were the total postoperative tube indwelling time, post-pleurodesis tube indwelling time, and hospital stay. A propensity score-matched analysis was performed.

Results

In the autologous blood patch pleurodesis and 50% glucose solution groups, the mean initiation timing of postoperative pleurodesis were 2.06±1.62 and 3.28±1.56 days, the mean duration of the tube indwelling time after surgery was 6.58±3.02 and 6.42±4.92 days, and the mean duration of the tube indwelling time after pleurodesis, it was 4.53±3.10 and 3.11±4.80 days, respectively. In addition, the total length of hospital stay was 9.11±5.42 and 7.83±4.75 days in the autologous blood patch pleurodesis and 50% glucose solution groups, respectively.

Conclusion

Early postoperative air leak cessation with autologous blood patch pleurodesis or 50% glucose solution pleurodesis is a feasible procedure with acceptable outcomes that effectively shortens the hospital stay.

Alternative management of intractable chylous ascites following robot-assisted pancreaticoduodenectomy of Viscum album sclerotherapy: a case report

A patient showed signs of fever and Hemovac insertion site discharge 8 days after surgery and was admitted. Abdominal paracentesis found milky ascites with triglyceride levels of the peritoneal fluid as high as 1,603 g/mL. Diagnosed as chylous ascites, symptomatic therapy such as empirical antibodies and diuretics was administered with paracentesis before being discharged. The ascites volume increased again, and the patient was re-admitted. The patient was treated with orlistat, octreotide, total parenteral nutrition administration, ascites drainage, and diuretics. Ascites levels increased further and intraperitoneal Viscum was administered. Clear ascites was observed, and the patient was discharged. We reported a case where conventional treatment for chylous ascites that occurred after pancreaticoduodenectomy was shown to be ineffective while Viscum extracted from mistletoe was able to manage chylous ascites.

Simultaneous Viscum pleurodesis and video-assisted thoracic surgery (VATS) bullectomy in patients with primary spontaneous pneumothorax

Although surgery is the gold standard for treatment of primary spontaneous pneumothorax (PSP), recurrence after surgery remains a concern. This study sought to evaluate the efficacy of simultaneous pleurodesis using Viscum album (VA) extract and video-assisted thoracic surgery (VATS) bullectomy for the treatment of PSP. From March 2016 to June 2020, 175 patients with PSP underwent bullectomy and intraoperative pleurodesis with VA extract at a single institution. All operations were performed through thoracoscopy by one surgeon. Upon completion of bullectomy, a polyglycolic acid sheet was used to cover the stapler lines, and 40 mg of VA extract was instilled over the entire chest wall before chest tube placement. The median operating time was 20 min (interquartile ranges, 15–30) and the median indwelling time of chest drainage was 2 days (interquartile ranges, 2–3). There were no postoperative complications over grade 3. During the median follow-up period of 38 months (interquartile ranges, 15–48), no recurrence of pneumothorax was observed. The results of this study demonstrated that simultaneous Viscum pleurodesis and VATS bullectomy provides a feasible and effective treatment option for preventing postoperative pneumothorax in patients with PSP.
