Intrathoracic gastric perforation: a late complication of an unknown postpartum recurrent hiatal hernia
No full textDiaphragmatic hernias occurring during pregnancy are an uncommon event. In very rare occasions, the clinical situation can suddenly worsen due to obstruction, torsion or infarction of the herniated viscera. Here, we describe a challenging case of a post-partum diaphragmatic hiatus hernia complicated by intrathoracic gastric perforation. A 23-year old woman was admitted at our hospital with a syndrome characterized by epigastralgy, dyspnoea and fever. She had previously undergone a laparoscopic antireflux surgery for hiatus hernia (6 years before) and a recent (4 months) unremarkable vaginal delivery. Due to the persistence of a pelvic pain after the delivery, she had been taking pain-killers as a self-administered medication. A CT scan showed a massive left pleural effusion and a complete herniation of the stomach into the left hemithorax. After placing a chest drainage and removing up to 3000 ml of brownish purulent fluid, a repeat CT scan (with water soluble contrast swallow) showed a leak at the level of the stomach. At surgery, we observed a complete intrathoracic herniation through a large diaphragmatic hiatal defect and a small well-defined gastric ulcer. A primary repair of both the stomach and the diaphragm was performed. We take the opportunity presented by this report to briefly discuss the patho-physiological mechanisms underlying this unusual complication

Surgeon experience influence lymphadenectomy during VATS lobectomy: National VATS database results
No full textObjectives: Aim of this study is to identify the factors that may influence the lymphadenectomy during VATS anatomical lung resection with particular interest on operator experience. Materials and methods: Clinical and pathological data from the prospective VATS Italian nationwide registry were reviewed and analysed. Patients with incomplete data regarding tumor and surgical characteristics, GGO, or with distant metastases were excluded. Patients clinical data, tumor characteristics, operation information and surgeon experience were collected and compared to resected lymph nodes number (#RN), resected N2 nodes number (#N2RN) and resected N2 stations number. A multivariable model was built using logistic regression analysis. Surgeon experience was categorized considering the number of VATS major anatomical resection and years after residency. Results: The final analysis was conducted on 3727 patients. The median #RN and #N2RN were 11 (1-51) and 5 (0-41). Regarding the analysed outcomes, #N2RN > 6 resulted in 1812 (48.8%)cases, #RN > 10 in 2124 (57.0%)cases and more than 3 N2 stations were harvested in 1447 (38.8%)patients. First operator experience with number of VATS lobectomies>50 (p < 0.001), operator seniority after residency5-10years (p < 0.001), cTNM II/III(p = 0.017), lobectomy/bilobectomy vs segmentectomy (p < 0.001), and upper/middle lobe tumor location (p < 0.005)resulted significantly associated to #N2RN > 6 at the multivariable analysis. First operator experience with number of VATS lobectomies>50 (p < 0.001), operator seniority after residency5-10years (p < 0.001) and lobectomy/bilobectomy (p < 0.001) resulted significantly associated to #RN > 10 at the multivariable analysis. Conclusions: Our study showed that lymphadenectomy during VATS lobectomy is influenced by tumor factors such as cTstage and tumor location but also by operator experience, with a higher number of resected lymph nodes in surgeons with a high number of VATS procedures and years after residency compared to surgeons with less experience
Type of lymphadenectomy does not influence survival in pIa NSCLC patients who underwent VATS lobectomy: Results from the national VATS group database
No full textIntroduction: Stage Ia presents an optimal survival rate after surgical resection, but the type of lymphadenectomy to use in these patients is still debated. The aim of this study is evaluate if one type of lymphadenectomy adopted influences survival in patients who underwent VATS lobectomy for stage Ia NSCLC.Methods: Clinical and pathological data from pIa patients in the prospective VATS Italian nationwide registry were reviewed and analysed. Patients and tumour characteristics,type of lymphadenectomy (sampling or radical nodal dissection,MRLD), were collected and correlated to Overall Survival(OS) and Disease free Survival(DFS). The Kaplan-Meier product-limit method was used to estimate OS and DFS and the log-rank test was adopted to evaluate the differences between groups. A propensity match was performed to reduce bias due to the retrospective study design.Results: The final analysis was conducted on 2039 patients, 179 died during follow-up,recurrence rate was 13%. MRLD was performed in 1287(63.1%)patients. The univariable analysis identified as favourable prognostic factors for OS the female sex(p = 0.023), low ECOG-score(0.008),low SUVmax(p < 0.001), GGO appearance(p < 0.001), pT < 2 cm(p = 0.002) and low tumour grading(p = 0.002). The multivariable analysis confirmed as independent prognostic factors low ECOG-score(p = 0.012), low SUVmax(p < 0.001) and low tumour grading(p < 0.001). Analysing survival in patients with solid/sub-solid nodules and after propensity score matching for pTdimension and number of N2 resected lymphnodes, no OS differences were present comparing sampling vs MRLD.Conclusion: Survival in pIa patients seems to be determined by patient and tumour characteristics such as performance status,grading and SUVmax. Type of lymphadnectomy did not seem to be correlated with OS in these patients

Prognostic factors for survival in advanced thymomas: The role of the number of involved structures
No full textBackground and Objectives The Masoka-Koga and tumor node metastases staging systems for thymoma are based on structures involved, but the prognostic role of the number of infiltrated/involved structures is still debated. We analyzed the prognostic role of involved structures and their combinations in locally advanced thymomas patients. Methods Data on 174 surgically treated locally advanced thymoma patients from 1/01/1990 to 31/12/2015 were reviewed. Clinical and pathological characteristic, involved structures, number of involved structures and different combinations were correlated to cancer specific survival (CSS) using Kaplan-Meier product-limit method. Results Five and 10-year CSS was 92% and 87%. Masaoka Stage 3 (p < 0.001), absence of pericardial involvement (p = 0.001), number of involved structures (p = 0.018), R0 (p < 0.001) and adjuvant radiotherapy (p = 0.008) were favorable prognostic CSS factors. A significant better prognosis was present in <= 2 involved structures vs >2 involved structures (5- and 10-year CSS: 95% and 93% vs. 80% and 51%). Multivariable analysis confirmed as independent prognostic factor R0 (p = 0.033, hazard ratio [HR]: 0.093, 95% confidence interval [CI] 0.010-0.827) and number of involved structures (p = 0.046, HR: 0.187, 95% CI: 0.036-0.968). In Masaoka Stage 3, patients with <= 2 involved structures had a significant better CSS than patients with >2 (10-year CSS: 98% vs. 73%, p = 0.008). Conclusions The number of involved structures and the concomitant involvement of the pericardium seems to be associated with a poor prognosis in surgically treated advanced thymoma patients
Surgeon experience does not influence nodal upstaging during vats lobectomy: Results from a large prospective national database
Full text linkBackground: Despite recent improvement in preoperative staging, nodal and mediastinal upstaging occur in about 5% to 15% of cN0 patients. Different clinical and tumor characteristics are associated with upstaging, whereas the role of the surgeon's experience is not well evaluated. This study aimed to investigate if operator experience might influence nodal upstaging during video-assisted thoracic surgery anatomical lung resection. Methods: Clinical and pathological data from the prospective video-assisted thoracic surgery Italian nationwide registry were reviewed and analyzed. Patients with incomplete data about tumor and surgical characteristics, ground glass opacities tumors, cN2 to 3, and M+ were excluded. Clinical data, tumor characteristics, and surgeon experience were correlated to nodal and mediastinal (N2) upstaging using Pearson's χ2 statistic or Fisher exact test for categorical variables and Mann-Whitney U and t tests for quantitative variables. A multivariable model was built using logistic regression analysis. Surgeon experience was categorized considering the number of video-assisted thoracic surgery major anatomical resections and years after residency. Results: Final analysis was conducted on 3,319 cN0 patients for nodal upstaging and 3,471 cN0N1 patients for N2 upstaging. Clinical tumor-nodes-metastasis stage was stage I in 2,846 (81.9%) patients, stage II in 533 (15.3%), and stage III (cT3N1) in 92 (2.8%). Nodal upstaging occurred in 489 (13.1%) patients, whereas N2 upstaging occurred in 229 (6.1%) patients. Years after residency (P = .60 for nodal, P = .13 for N2 upstaging) and a number of video-assisted thoracic surgery procedures(P = .49 for nodal, P = .72 for nodal upstaging) did not correlate with upstaging. Multivariable analysis confirmed cT-dimension (P = .001), solid nodules (P < .001), clinical tumor-nodes-metastasis (P < .001) and maximum standardized uptake values (P < .001) as factors independently correlated to nodal upstaging, whereas cT-dimension (P = .005), clinical tumor-nodes-metastasis (P < .001) and maximum standardized uptake values (P = .028) resulted independently correlated to N2 upstaging. Conclusion: Our study showed that surgeon experience did not influence nodal and mediastinal upstaging during -assisted thoracic surgery anatomical resection, whereas cT-dimension, clinical tumor-nodes-metastasis, and maximum standardized uptake values resulted independently correlated to nodal and mediastinal upstaging
