Objective: To evaluate the clinical outcomes, histopathological features, and obstetric and oncological outcomes of uterine smooth muscle tumor of uncertain malignant potential (STUMP).
Methods: We conducted a single-center, database review of patients with STUMP between January 2001 and December 2015. We investigated the clinical, operative, histopathologic, recurrence, and fertility outcomes of the included cases.
Results: Nineteen patients with STUMP were studied. Three were reclassified as sarcoma after slide review, and 16 patients were finally included in the study. The mean age was 45 years. Ki-67 expression was ≥10% in 25.0% of cases and 30% in the only recurrent case. Recurrence occurred 52 months after a diagnosis of STUMP in a 56-year-old female patient who underwent hysterectomy. Two of six patients who underwent myomectomy had fertility requirements, and both successfully delivered babies without recurrence. Recurrence was not related to mitosis, degree of atypia, or necrosis. There was also no relationship between type of surgery or surgical approach and recurrence.
Conclusions: Patients with STUMP warrant a pathological review process in centers with experience. Fertility-preservation is worth attempting, but young patients must be followed-up closely. Ki-67 might be a valuable marker predicting recurrence.

Intrapericardial Pulmonary Vein Ligation to Prevent Stump Thrombosis During Left Upper Lobectomy.
Ann Thorac Surg Short Rep

Background: Postoperative cerebral infarction, a serious complication of surgery, is occasionally experienced with pulmonary vein stump thrombosis (PVST), which is frequently observed after left upper lobectomy (LUL). Herein, we prospectively investigated whether PVST could be safely prevented by intrapericardial ligation of the superior pulmonary vein (SPV) to shorten the SPV stump during LUL.
Methods: In a consecutive 21 patients who underwent LUL, we ligated the proximal intrapericardial SPV with 1-0 silk suture and divided the distal hilar SPV by an automatic stapling device.
Percutaneous transhepatic arterial access for coil embolization of hepatic artery infusion pump-associated bleeding.

Background: Hepatic artery infusion pump (HAIP) chemotherapy is a locoregional treatment for intrahepatic malignancies. HAIPs are surgically implanted, and the catheter tip is typically inserted into a ligated gastroduodenal artery stump. Potential complications at the catheter insertion site include dehiscence, pseudoaneurysm or extravasation, and adjacent hepatic arterial stenosis and thrombosis.

There is renewed interest in anterior cruciate ligament (ACL) preservation techniques. Prior studies have shown good outcomes and low failure rates with ACL preservation in patients with good tissue quality and more proximal tears. We describe a technique intended to assist surgeons in obtaining maximal length of the ACL stump during ACL preservation surgery.

Objective: The objective of this study was to investigate the utility of preoperative 18F-FDG PET/CT scanning in preoperative evaluation and surgical planning for pulmonary tuberculosis.
Methods: The study involved a retrospective analysis of clinical data and preoperative chest 18F-FDG PET/CT data of 24 patients with pulmonary tuberculosis who underwent pneumonectomy at the Shanghai Public Health Clinical Center between December 2017 and January 2022.
Results: All 24 patients successfully underwent chest 18F-FDG PET/CT imaging, and complete data pertaining to the maximum standardized uptake value, mean standardized uptake value, minimum standardized uptake value, total lesion glycolysis, and metabolic tumor volume were obtained.
Encountering Arc of Bühler during pancreaticoduodenectomy surgery.

The Arc of Bühler (AoB) is a rare anatomical variant in gastrointestinal vasculature where there is an aberrant anastomotic vessel between coeliac and superior mesenteric arteries. We present a rare case where AoB was noted intraoperatively to have haemodynamically significant flow in the context of coeliac artery stenosis, supplementing arterial supply to the hepatic artery proper via the gastroduodenal artery (GDA). An interpositional jump graft between the aorta and the GDA stump was created using the long saphenous vein, and flow was restored.
