The effectiveness and safety of computed tomographic peritoneography and video-assisted thoracic surgery for hydrothorax in peritoneal dialysis patients: A retrospective cohort study in Japan.

ABSTRACT: INTRODUCTION:Albeit uncommon, hydrothorax is an important complication of peritoneal dialysis (PD). Due to paucity of evidence for optimal treatment, this study aimed to evaluate the effectiveness and safety of computed tomographic (CT) peritoneography and surgical intervention involving video-assisted thoracic surgery (VATS) for hydrothorax in a retrospective cohort of patients who underwent PD in Japan. METHODS:Of the 982 patients who underwent PD from six centers in Japan between 2007 and 2019, 25 (2.5%) with diagnosed hydrothorax were enrolled in this study. PD withdrawal rates were compared between patients who underwent VATS for diaphragm repair (surgical group) and those who did not (non-surgical group) using the Kaplan-Meier method and log-rank test. RESULTS:The surgical and non-surgical groups comprised a total of 11 (44%) and 14 (56%) patients, respectively. Following hydrothorax diagnosis by thoracentesis and detection of penetrated sites on the diaphragm using CT peritoneography, VATS was performed at a median time of 31 days (interquartile range [IQR], 20-96 days). During follow-up (median, 26 months; IQR, 10-51 months), 9 (64.3%) and 2 (18.2%) patients in the non-surgical and surgical groups, respectively, withdrew from PD (P = 0.021). There were no surgery-related complications or hydrothorax relapse in the surgical group. CONCLUSIONS:This study demonstrated the effectiveness and safety of CT peritoneography and VATS for hydrothorax. This approach may be useful in hydrothorax cases to avoid early drop out of PD and continue PD in the long term. Further studies are warranted to confirm these results.

Project description:Minimally invasive surgical techniques offer several advantages over traditional open procedures, yet the pathway to minimally invasive proficiency can be difficult to navigate. As a part of an effort of the Joint Council of Thoracic Surgical Education to increase access to this skill set in the general thoracic community, recent graduates of thoracic residencies were surveyed to determine the self-reported achievement of video-assisted thoracic surgery (VATS) lobectomy proficiency and the merits of various educational opportunities. The objective of this study was to estimate the comfort level of recent graduates with the minimally invasive approach, as this demographic not only reflects the current status of training, but represents the future of the specialty. Surgeons graduating North American thoracic residencies between 2006 and 2008 identifying themselves as practitioners of general thoracic surgery were surveyed. A total of 271 surgeons completed training between 2006 and 2008 and indicated general thoracic to be a part of their practice (84 dedicated thoracic and 187 mixed). One hundred and forty-six surgeons completed the survey (54%) including 74 of 84 (88%) dedicated thoracic surgeons. Overall, 58% of recent graduates who perform general thoracic procedures consider themselves proficient in VATS lobectomies (86% of dedicated thoracic surgeons and 28% of surgeons with a mixed practice, P < 0.0001). Of surgeons considering themselves to be proficient at VATS lobectomies, 66% felt thoracic residency was critical or very important to achieving proficiency. Fellowships after completing board residency, animal labs, and follow-up VATS courses put on by experts were much less consistently beneficial. The vast majority of the 25 dedicated general thoracic surgeons who graduate each year consider themselves proficient in VATS lobectomies, largely due to training in their thoracic residencies. On the other hand, the minority of surgeons performing general thoracic procedures as a part of a mixed practice consider themselves proficient in VATS lobectomies. Further study is warranted to enhance the VATS lobectomy experience of mixed practice surgeons particularly during their thoracic residencies.

Project description:Background:Pulmonary segmentectomies are generally classified into simple (tri-segmentectomy or lingulectomy as well as apical or basilar segmentectomy) and complex (individual or bi-segmentectomy of the upper, middle and lower lobes). Complex segmentectomies are technically feasible by video-assisted thoracic surgery (VATS) but remain challenging, and reports on post-operative outcomes are scarce. This study analyzes the differences between simple and complex VATS segmentectomy in terms of peri- and post-operative outcomes. Methods:We retrospectively reviewed records of all patients who underwent anatomical pulmonary segmentectomy by VATS from 2014 to 2018 in two university hospitals. Results:A total of 232 patients (114 men; median age 67 years; range, 29-87 years) underwent VATS segmentectomy for primary lung cancer (n=177), metastases (n=26) and benign lesions (n=29). The overall 30-day mortality and morbidity rates were 0.8% and 29.7%, respectively. The re-operation rate was 4.7%. Complex segmentectomy was realized in 111 patients including 86 (77.5%) upper lobe segmentectomies and 44 (39.6%) bi-segmentectomies. There was no statistical difference between complex and simple segmentectomy in terms of operative time (145 vs. 143 min, respectively; P=0.79) and chest tube duration [median: 1 (range, 0-33) vs. 2 (range, 1-19) days, respectively; P=0.95]. Post-operative overall complication rates were similar for both groups (30% vs. 30%, respectively; P=0.99) and were not correlated with the type of segmentectomy. However, complex segmentectomy patients had a shorter length of hospitalization compared to simple segmentectomy patients [median: 5 (range, 1-36) vs. 7 (range, 2-31) days; P=0.026]. Interestingly, complex segmentectomies were realized most frequently 2 years after implementation of VATS segmentectomy (23% vs. 77%; P=0.01). Conclusions:In comparison with simple segmentectomy, complex segmentectomy by VATS seems to present similar post-operative complication rates. Learning curve and progressive increase in acceptance by surgeons seem to be key elements for successful implementation of complex segmentectomies and could explain the shorter length of stay we observed.
