BACKGROUND
The incidence of anastomotic leakage in gastrointestinal surgery is highest after esophagogastric anastomosis, with leakage rates of 10% to 38% still being reported, but little consensus as to cause or corrective. The role of anastomotic tension from a series of physiological forces acting on the anastomosis from the moment of recovery from anesthesia may be underestimated. It was hypothesized that anchoring the conduit in the mediastinum would provide the greatest protection during the vulnerable healing phase.
PATIENTS AND METHODS
A prospectively maintained database was interrogated for anastomotic leakage following the introduction of an anastomotic technique employing anchoring sutures where the gastric conduit was secured to the mediastinal pleura with 3 obliquely inserted load-bearing sutures. A contrast study was performed between days 5 and 7 and all intrahospital mortalities underwent autopsy. Clinical, radiological, and autopsy leaks were recorded.
RESULTS
Of 146 intrathoracic esophagogastric anastomoses in 144 patients, 81 (55%) of which were stapled, there was 1 clinical leak and 1 patient with an aortoenteric fistula, considered at autopsy to be possibly due to an anastomotic leak, to give an anastomotic leak rate of 2 in 146 (1.37%).
CONCLUSION
The low anastomotic leak rate in this series is potentially due to the protective effect of anchoring sutures, the chief difference from an otherwise standard anastomotic technique. These sutures protect the anastomosis from a series of distracting forces during the most vulnerable phase of healing. It is intuitive that the absence of tension would also reduce any risk posed by a minor impairment of blood supply or any imperfection of the technique.

Investigation of the efficacy and feasibility of combined therapy of PD-L1-enhanced exogenous peripatetic adoptive natural killer (NK) cells in combination with antiangiogenic targeted therapy in the treatment of extensive-stage small cell lung cancer.
A 67-year-old male patient presented with extensive-stage small cell lung cancer with the primary lesion located in the right upper lung, accompanied by multiple metastases to the pleura and abdominal cavity with enlarged mediastinal lymph nodes. A combination therapy approach was used to target the patient's multiple systemic metastases after localized radiotherapy. The approach involved adoptive transfer of programmed death ligand 1 (PD-L1) enhanced exogenous natural killer (NK) cells, along with antiangiogenic treatment. Allogeneic cord blood NK cells were infused back into the patient over two consecutive days. On the first day, the treatment was followed by a dose of 1200 mg of atezolizumab. Subsequently, the patient received a daily dose of 10 mg of anlotinib administered orally for 14 days. This was followed by a 7-day break, and each cycle lasted 21 days. After delivering localized radiation to the primary lesion in the right lung and metastatic mediastinal lymph nodes, complete remission was achieved in the local lesion, effectively avoiding the risk of superior vena cava syndrome. Following six cycles of combined therapy, most of the metastatic lesions had disappeared, and the remaining metastatic lesions had significantly reduced in size. The recent therapeutic effect resulted in partial remission. The combination therapy of immune checkpoint inhibitor PD-L1-enhanced exogenous adoptive transfer NK cells, along with antiangiogenic targeted treatment, demonstrated a satisfactory short-term effect, with disappearance of most of the metastases and noticeable shrinkage in the remaining metastatic lesions.

Pleural epithelioid hemangioendothelioma (EHE) is a rare malignancy of vascular origin. It can affect various organs; pleural involvement is rare and lack of suspicion leads to delay in diagnosis. We present a case of pleural EHE with metastasis to lung parenchyma that presents with chest pain and dyspnea. Chest imaging showed loculated pleural effusion, pleural thickening, mediastinal lymphadenopathy, and pulmonary nodules.

INTRODUCTION AND IMPORTANCE
Echinococcus granulosus causes hydatid disease. The most affected organ is the liver which is followed by the lungs. The pleural cavity being the primary location of hydatid cysts is rare and should be discussed further. This paper documents a rare case of primary pleural hydatidosis which can present with a merely isolated cough followed by dyspnea. The diagnosis and surgical treatment along with post-operative medications are vital in this case.
CASE PRESENTATION
We present a case of a 45-year-old who suffered from a cough for more than one week which did not subside after taking medications. This symptom was followed by dyspnoea for which an X-ray was done which showed left-sided pleural effusion, a complication of pleural hydatidosis. Computed tomography showed multiple cysts in the pleural cavity which confirmed the diagnosis of primary pleural hydatidosis as the cysts were not present in any other sites. Blood work revealed eosinophilia which is significant in parasitic diseases. A left posterolateral thoracotomy was performed, and the cysts were surgically removed. Additionally, empyemectomy and pleurectomy were done. The patient was then treated with anti-parasitic therapy and was advised to get X-rays during the follow-up visits. The X-rays were normal and indicated that there was no disease recurrence.
CLINICAL DISCUSSION
Echinococcus granulosus is a parasitic worm that causes hydatid disease. The primary location is the liver. A diagnosis of intrathoracic but extrapulmonary disease, which involves the presence of hydatid cysts in the pleura, heart, pericardium, mediastinum, chest wall, and diaphragm, is difficult in individuals lacking a primary cyst in a common location (Isitmangil et al., 2003; Saeedan et al., 2020).
CONCLUSION
This case implies the significance of a cough of more than a week that is not relieved by medications. This should be carefully evaluated and followed in cases that have a rare diagnosis requiring surgery. A diagnosis of primary pleural hydatidosis with left-sided pleural effusion and atelectasis with mediastinal shift to the right side was made which was treated with a surgical procedure.

Review
The paraspinal region encompasses all tissues around the spine. The regional anatomy is complex and includes the paraspinal muscles, spinal nerves, sympathetic chains, Batson's venous plexus and a rich arterial network. A wide variety of pathologies can occur in the paraspinal region, originating either from paraspinal soft tissues or the vertebral column. The most common paraspinal benign neoplasms include lipomas, fibroblastic tumours and benign peripheral nerve sheath tumours. Tumour-like masses such as haematomas, extramedullary haematopoiesis or abscesses should be considered in patients with suggestive medical histories. Malignant neoplasms are less frequent than benign processes and include liposarcomas and undifferentiated sarcomas. Secondary and primary spinal tumours may present as midline expansile soft tissue masses invading the adjacent paraspinal region. Knowledge of the anatomy of the paraspinal region is of major importance since it allows understanding of the complex locoregional tumour spread that can occur via many adipose corridors, haematogenous pathways and direct contact. Paraspinal tumours can extend into other anatomical regions, such as the retroperitoneum, pleura, posterior mediastinum, intercostal space or extradural neural axis compartment. Imaging plays a crucial role in formulating a hypothesis regarding the aetiology of the mass and tumour staging, which informs preoperative planning. Understanding the complex relationship between the different elements and the imaging features of common paraspinal masses is fundamental to achieving a correct diagnosis and adequate patient management. This review gives an overview of the anatomy of the paraspinal region and describes imaging features of the main tumours and tumour-like lesions that occur in the region.

RATIONALE
To explore the clinical role of F-fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT) in differentiating malignant pleural effusion (MPE) from benign pleural effusion (BPE) in patients with lung cancer.
METHODS
Over a 8-year period, we retrospectively reviewed PET/CT data of lung cancer patients with pleural effusion, with 237 participants enrolled for analysis. The nature of pleural effusion was confirmed using pleural cytology or biopsy. MPE versus BPE comparison and multiple regression analysis were performed. Receiver operating characteristic (ROC) curve analysis was used for evaluating the diagnostic performance.
RESULTS
Of the 237 participants, 170 had MPEs and 67 had BPEs. Compared with BPEs, MPEs had higher pleural SUVmax and thicker pleura and were more common among non-small cell lung cancers, peripheral tumors, and women (p < 0.05). BPEs had larger and higher F-FDG uptake thoracic lymph nodes and more complications of pneumonia (p < 0.05) than MPEs. Multiple regression analysis was used to identify the pleural SUVmax (odds ratio, OR = 38.8), sex (OR = 0.033), and mediastinal lymphoid node size (OR = 0.86) as independent risk factors for MPEs. The sensitivity, specificity, and area under the ROC curve (AUC) in the combined ROC curve analysis by using the three factors were 95.3%, 95.5%, and 0.989, respectively.
CONCLUSION
F-FDG PET/CT integrated imaging is an effective non-invasive method for differential diagnosis of MPE in patients with lung cancer. Pleural SUVmax combined with thoracic lymph nodes and sex has high diagnostic value.
