Necrotic gangrenous intrathoracic appendix in a marfanoid adult patient: a case report
BACKGROUND: A diaphragmatic hernia is defined as a defect in part of the diaphragm through which abdominal contents can protrude into the thorax. It may be congenital or acquired. In this case report, we aim to demonstrate a congenital diaphragmatic hernia in an adult marfanoid patient which required emergency treatment CASE PRESENTATION: A 43 year old woman was admitted with classical appendicitis requiring surgery. She incidentally had Marfan's clinical features with a positive family history for the syndrome. At operation she had grossly abnormal abdominal anatomy. Radiological investigations demonstrated a large right congenital diaphragmatic hernia with an intrathoracic hernial sac containing a perforated gangrenous appendix. The hernial sac was opened surgically and the appendix excised. The patient made a full recovery. CONCLUSION: Diaphragmatic hernias are usually congenital in nature often requiring early corrective surgery for future survival. We have demonstrated the presence of an unusually large diaphragmatic defect, almost a hemidiaphragmatic defect, of unknown direct etiology, but of some possible association with Marfan's syndrome in an adult patient presenting with an acute perforated gangrenous appendix requiring emergency life-saving surgery
Diaphragmatic rupture with right colon and small intestine herniation after blunt trauma: a case report
<p>Abstract</p> <p>Introduction</p> <p>Traumatic diaphragmatic hernias are an unusual presentation of trauma, and are observed in about 10% of diaphragmatic injuries. The diagnosis is often missed because of non-specific clinical signs, and the absence of additional intra-abdominal and thoracic injuries.</p> <p>Case presentation</p> <p>We report a case of a 59-year-old Italian man hospitalized for abdominal pain and vomiting. His medical history included a blunt trauma seven years previously. A chest X-ray showed right diaphragm elevation, and computed tomography revealed that the greater omentum, a portion of the colon and the small intestine had been transposed in the hemithorax through a diaphragm rupture. The patient underwent laparotomy, at which time the colon and small intestine were reduced back into the abdomen and the diaphragm was repaired.</p> <p>Conclusions</p> <p>This was a unusual case of traumatic right-sided diaphragmatic hernia. Diaphragmatic ruptures may be revealed many years after the initial trauma. The suspicion of diaphragmatic rupture in a patient with multiple traumas contributes to early diagnosis. Surgical repair remains the only curative treatment for diaphragmatic hernias. Prosthetic patches may be a good solution when the diaphragmatic defect is severe and too large for primary closure, whereas primary repair remains the gold standard for the closure of small to moderate sized diaphragmatic defects.</p
Chest Wall Resection for Adult Soft Tissue Sarcomas and Chondrosarcomas: Analysis of Prognostic Factors
Background: Wide resection with tumor-free margins is necessary in soft-tissue sarcomas to minimize local recurrence and to contribute to long-term survival. Information about treatment outcome and prognostic factors of adult sarcoma requiring chest wall resection (CWR) is limited. Methods: Sixty consecutive patients were retrospectively studied for overall survival (OS), local recurrence-free survival (LRFS), and disease-free survival (DFS). Twenty-one prognostic factors regarding survival were analyzed by univariate analysis using the Kaplan-Meier method and the log-rank test. Results: With a median survival of 2.5 years, the OS was 46% (33%) at 5 (10) years. The LRFS was 64% at 5 and 10 years, and the DFS was 30% and 25% at 5 and 10 years. At the end of the study period, 26 patients (43%) were alive, of which 20 patients (33%) had no evidence of disease and 40 patients (67%) had no chest wall recurrence. In the group of 9 patients with a radiation-induced soft-tissue sarcoma, the median survival was 8 months. Favorable outcome in univariate analysis in OS and LRFS applied for the low-grade sarcoma, bone invasion, and sternal resection. For OS only, age below 60 years and no radiotherapy were significant factors contributing to an improved survival. CWR was considered radical (R0) at the pathological examination in 43 patients. There were 52 patients with an uneventful recovery. There was one postoperative death. Conclusions: CWR for soft-tissue sarcoma is a safe surgical procedure with low morbidity and a mortality rate of less than 1%. With proper patient selection acceptable survival can be reached in a large group of patients. Care must be given to patients with radiation-induced soft-tissue sarcoma who have a significantly worse prognosis
Acromegaly caused by growth hormone-releasing hormone-producing tumors: long-term observational studies in three patients
We report on three newly diagnosed patients with extracranial ectopic GHRH-associated acromegaly with long-term follow-up after surgery of the primary tumor. One patient with a pancreatic tumor and two parathyroid adenomas was the index case of a large kindred of MEN-I syndrome. The other two patients had a large bronchial carcinoid. The first patient is still in remission now almost 22 years after surgery. In the two other patients GHRH did not normalize completely after surgery and they are now treated with slow-release octreotide. IGF-I normalized in all patients. During medical treatment basal GH secretion remained (slightly) elevated and secretory regularity was decreased in 24 h blood sampling studies. We did not observe development of tachyphylaxis towards the drug or radiological evidence of (growing) metastases. We propose life-long suppressive therapy with somatostatin analogs in cases with persisting elevated serum GHRH concentrations after removal of the primary tumor. Independent parameters of residual disease are elevated basal (nonpulsatile) GH secretion and decreased GH secretory regularity
Cellular Basis of Tissue Regeneration by Omentum
The omentum is a sheet-like tissue attached to the greater curvature of the stomach and contains secondary lymphoid organs called milky spots. The omentum has been used for its healing potential for over 100 years by transposing the omental pedicle to injured organs (omental transposition), but the mechanism by which omentum helps the healing process of damaged tissues is not well understood. Omental transposition promotes expansion of pancreatic islets, hepatocytes, embryonic kidney, and neurons. Omental cells (OCs) can be activated by foreign bodies in vivo. Once activated, they become a rich source for growth factors and express pluripotent stem cell markers. Moreover, OCs become engrafted in injured tissues suggesting that they might function as stem cells

Uniportal Versus Multiportal Video-Assisted Thoracoscopic Lobectomy for Lung Cancer: An Updated Meta-analysis
Objective: We reviewed the available literature on patients with lung cancer undergoing either uniportal (UVATS) or multiport video-assisted thoracoscopic surgery (MVATS). Methods: Original research studies that evaluated perioperative and long-term outcomes of UVATS versus MVATS were identified, from January 1990 to April 2020. The perioperative, along with the oncologic and long-term survival outcomes, were calculated according to either a fixed or a random effect model, appropriately. The Q statistics and I2 statistic were used to test for heterogeneity among the studies. Results: Twenty studies were included, incorporating a total of 1,469 patients treated with UVATS and 3,231 treated with MVATS. The incidence of complications was lower in patients treated with UVATS [OR: 0.76 (95% CI 0.62, 0.93); p = 0.008]. The chest tube duration was significantly lower in the UVATS group (WMD: − 0.63 [95% CI − 1.03, − 0.23]; p = 0.002). Length of hospital stay (L.O.S.) was also lower in the UVATS patient group (WMD: − 0.54 [− 0.94, − 0.13]; p = 0.009), along with postoperative pain [WMD: − 0.57 (95% CI − 0.97, − 0.18); p = 0.004]. No significant differences were found regarding the mean operative time (M.O.T.), mean blood loss, the number of resected lymph nodes, the 30-day mortality, along with the survival at 1 and 3 years postoperatively. Conclusions: The present meta-analysis indicates that UVATS is associated with enhanced outcomes in patients undergoing surgery for lung cancer. Well-designed, randomized studies, comparing UVATS to MVATS, are necessary to further assess their long-term clinical outcomes. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC part of Springer Nature

Updated meta-analysis of survival after extrapleural pneumonectomy versus pleurectomy/decortication in mesothelioma
Objective: We reviewed the available literature on patients with MPM undergoing either extrapleural pneumonectomy (EPP) or pleurectomy/decortication (P/D). Methods: Original research studies that evaluated long-term outcomes of P/D versus EPP were identified, from January 1990 to July 2018. The 30 and 90 days mortality, along with the 1-, 2-, 3-, 5-year survival, the median overall survival and the complications were calculated according to both a fixed and a random effect model. The Q statistics and I 2 statistic were used to test for heterogeneity among the studies. Results: Fifteen studies were included, incorporating a total of 1672 patients treated with EPP and 2236 treated with P/D. The 30-day mortality was significantly higher in the EPP group [OR 3.24 (95% CI 1.70, 6.20); p < 0.001]. The median overall survival was significantly increased in the P/D group [WMD − 4.20 (− 5.66, − 2.74); p < 0.001]. No significant differences were found regarding the 90-day mortality and the 1-, 2-, 3-, 5-year survival between the EPP and P/D groups. The incidence of postoperative atrial fibrillation, hemorrhage, empyema, bronchopleural fistula and air leak was significantly increased in the EPP group (p < 0.05). Conclusions: The present meta-analysis indicates that P/D is associated with enhanced outcomes regarding 30-day mortality, median overall survival, and complications. The P/D approach, should, therefore be preferred when technically feasible. However, the decision regarding the procedure of choice should be made on the basis of the disease status and the surgeon’s experience. Well-designed, randomized studies, comparing EPP to P/D, are necessary to further assess their clinical outcomes. © 2018, The Japanese Association for Thoracic Surgery
