Background:
Using a previously unreported Peruvian registry of patients treated for early-stage non-small cell lung cancer (NSCLC), this study explored whether wedge resection and lobectomy were equivalent regarding survival and impact on radiologic-pathologic variables.
Methods:
This observational, analytical, longitudinal study used propensity scorematched (PSM) analysis of a single-center retrospective registry of 2,570 patients with pathologic stage I–II NSCLC who were treated with wedge resection (n=1,845) or lobectomy (n=725) during 2000–2020. After PSM, 650 cases were analyzed (resection, n=325;lobectomy, n=325) through preoperative and clinical variables, including patients with ≥1 lymph node removed. Kaplan-Meier curves and multivariable Cox proportional hazard models were created for 5-year overall survival (OS), disease-free survival (DFS), and locoregional-recurrence-free survival (LRFS).
Results:
The principal complication was operative pain persisting >7 days for lobectomy versus wedge resection (58% vs. 23%, p=0.034) and shorter hospital stays for resection than for lobectomy (5.3 days vs. 12.8 days, p=0.009). The 5-year OS (84.3% vs. 81.2%, p=0.09) and DFS (79.1% vs. 74.1%, p=0.07) were similar and statistically insignificant between resections and lobectomies, respectively. LRFS was worse overall following wedge resection than lobectomy (79.8% vs. 91.1%, p<0.02). Nevertheless, in the PSM analysis, both groups experienced similar LRFS when the resection margin was >10 mm (90.9% vs. 87.3%, p<0.048) and ≥4 lymph nodes were removed (82.8% vs. 79.1%, p<0.011).
Conclusion
Both techniques led to similar OS and DFS at 5 years; however, successful LRFS required a wedge resection with a surgical margin and adequate lymph node removal to obtain outcomes similar to lobectomy.

Congenital diaphragmatic hernia consists of a defect in the embryonic development of the diaphragm that allows the passage of the abdominal viscera into the thoracic cavity, its diagnosis during pregnancy is quite rare. We present the case of a 31-year-old woman, with 23 weeks of gestation, who consulted for epigastric pain, nausea, and repetitive emetic episodes, without improvement with the medication provided. Due to the intense abdominal pain, a computed tomography of the abdomen and thorax was performed where the 28 mm defect was found at the left diaphragmatic level with protrusion of the gastric fundus to the thoracic cavity. She was taken to surgical management by laparoscopy with abdominal and thoracic approach, with a successful result and without maternal perinatal complications. Although the integrity of the diaphragmatic suture could be feared in relation to the increase in intraabdominal pressure due to uterine growth, the evolution of our patient and previous reports show that postoperative complications are not frequent. Successful vaginal delivery has even been described in some reports. Diaphragmatic hernias diagnosed during pregnancy are quite rare. We suggest that the optimal management of them during pregnancy is immediate surgical correction in case of persistent symptoms, more studies are needed to establish firm recommendations on the management of this pathology.
