Risk of venous thromboembolism in patients undergoing gastric cancer surgery: a systematic review and meta-analysis

BMC Cancer. 2023 Oct 3;23(1):933. doi: 10.1186/s12885-023-11424-x.

ABSTRACT

BACKGROUND: Venous thromboembolism (VTE) is a common postoperative complication in patients undergoing surgery for gastric cancer (GC). Although VTE incidence may vary among cancers, guidelines rarely stratify preventive methods for postoperative VTE by cancer type. The risk of VTE in patients undergoing surgery for GC remains unclear.

METHODS: A systematic review and meta-analysis was undertaken to determine the risk of VTE after GC surgery and discuss the clinical value of pharmacological thromboprophylaxis in these cases. Medline, Embase, Web of Science, and Cochrane Library databases were searched for articles published from their inception to September 2022.

RESULTS: Overall, 13 studies (111,936 patients) were included. The overall 1-month incidence of VTE, deep vein thrombosis (DVT), and pulmonary embolism (PE) after GC surgery was 1.8% (95% CI, 0.8-3.1%; I²=98.5%), 1.2% (95% CI, 0.5-2.1%; I²=96.1%), and 0.4% (95% CI, 0.1-1.1%; I²=96.3%), respectively. The prevalence of postoperative VTE was comparable between Asian and Western populations (1.8% vs. 1.8%; P > 0.05). Compared with mechanical prophylaxis alone, mechanical plus pharmacological prophylaxis was associated with a significantly lower 1-month rate of postoperative VTE and DVT (0.6% vs. 2.9% and 0.6% vs. 2.8%, respectively; all P < 0.05), but not PE (P > 0.05). The 1-month postoperative incidence of VTE was not significantly different between laparoscopic and open surgery (1.8% vs. 4.3%, P > 0.05).

CONCLUSION: Patients undergoing GC surgery do not have a high risk of VTE. The incidence of VTE after GC surgery is not significantly different between Eastern and Western patients. Mechanical plus pharmacological prophylaxis is more effective than mechanical prophylaxis alone in postoperative VTE prevention. The VTE risk is comparable between open and laparoscopic surgery for GC.

Anticoagulation for the treatment of septic cerebral venous sinus thrombosis in the setting of pediatric sinogenic and otogenic intracranial infections

Neurosurg Focus. 2023 Oct;55(4):E8. doi: 10.3171/2023.7.FOCUS23374.

ABSTRACT

OBJECTIVE: Septic cerebral venous sinus thrombosis (CVST) is a recognized complication of pediatric sinogenic and otogenic intracranial infections. The optimal treatment paradigm remains controversial. Proponents of anticoagulation highlight its role in preventing thrombus propagation and promoting recanalization, while others cite the risk of hemorrhagic complications, especially after a neurosurgical procedure for an epidural abscess or subdural empyema. Here, the authors investigated the diagnosis, management, and outcomes of pediatric patients with sinogenic or otogenic intracranial infections and a septic CVST.

METHODS: All patients 21 years of age or younger, who presented with an intracranial infection in the setting of sinusitis or otitis media and who underwent neurosurgical treatment at Connecticut Children's, Rady Children's Hospital-San Diego, or Ann and Robert H. Lurie Children's Hospital of Chicago from March 2015 to March 2023, were retrospectively reviewed. Demographic, clinical, and radiological data were systematically collated.

RESULTS: Ninety-six patients were treated for sinusitis-related and/or otitis media-related intracranial infections during the study period, 15 (15.6%) of whom were diagnosed with a CVST. Of the 60 patients who presented prior to the COVID-19 pandemic, 6 (10.0%) were diagnosed with a septic CVST, whereas of the 36 who presented during the COVID-19 pandemic, 9 (25.0%) had a septic CVST (p = 0.050). The superior sagittal sinus was involved in 12 (80.0%) patients and the transverse and/or sigmoid sinuses in 4 (26.7%). Only 1 (6.7%) patient had a fully occlusive thrombus. Of the 15 patients with a septic CVST, 11 (73.3%) were initiated on anticoagulation at a median interval of 4 (IQR 3-5) days from the most recent neurosurgical procedure. Five (45.5%) patients who underwent anticoagulation demonstrated complete recanalization on follow-up imaging, and 4 (36.4%) had partial recanalization. Three (75.0%) patients who did not undergo anticoagulation demonstrated complete recanalization, and 1 (25.0%) had partial recanalization. None of the patients treated with anticoagulation experienced hemorrhagic complications.

CONCLUSIONS: Septic CVST is frequently identified among pediatric patients undergoing neurosurgical intervention for sinogenic and/or otogenic intracranial infections and may have become more prevalent during the COVID-19 pandemic. Anticoagulation can be used safely in the acute postoperative period if administered cautiously, in a monitored setting, and with interval cross-sectional imaging. However, some patients exhibit excellent outcomes without anticoagulation, and further studies are needed to identify those who may benefit the most from anticoagulation.

Extended Venous Thromboembolism Prophylaxis after Robotic Staging for Endometrial Cancer

South Med J. 2023 Oct;116(10):790-794. doi: 10.14423/SMJ.0000000000001611.

ABSTRACT

OBJECTIVES: Our objectives were to estimate the incidence of venous thromboembolism (VTE) after robotic staging for endometrial cancer and to compare the incidence of VTE in patients who received a single dose of preoperative prophylaxis of enoxaparin with those who received extended postoperative prophylaxis.

METHODS: This study is a retrospective chart review of patients who underwent robot-assisted surgical staging for endometrial cancer. Patients were categorized into two groups: preoperative prophylaxis (PP), patients who received a single dose of enoxaparin preoperatively, and extended prophylaxis (EP), patients who received 28 days of enoxaparin postoperatively.

RESULTS: In total, 148 patients were included, with 117 patients in the PP group and 31 patients in the EP group. The overall incidence of VTE within 30 days postoperatively was 0.67%. No significant difference was found between the PP and the EP groups (0.9% and 0%, respectively; P = 1.00). Most patients in the cohort had endometrioid adenocarcinoma (78%) with low-grade disease (70%), although there were a greater number of patients in the PP group with uterine serous carcinoma compared with the EP group (17% vs 10%; P = 0.034). The PP group had higher estimated blood loss (106 vs 81 mL; P = 0.009) and longer operative times (178 vs 151 min; P = 0.028) compared with the EP group. Significantly more patients in the PP group underwent lymph node dissection compared with the EP group (32% vs 7%; P = 0.008).

CONCLUSIONS: The incidence of VTE following robot-assisted surgical staging for endometrial cancer in this study was 0.67%. No significant difference was found in VTE incidence between the PP group compared with the EP group. Mechanical prophylaxis plus a single dose of preoperative pharmacologic prophylaxis may suffice for low-risk patients following robotic surgical staging for endometrial cancer.

Major Intraoperative Complications During Minimally Invasive Esophagectomy

Ann Surg Oncol. 2023 Oct 2. doi: 10.1245/s10434-023-14340-3. Online ahead of print.

ABSTRACT

BACKGROUND: Studies have shown minimally invasive esophagectomy (MIE) to be a feasible surgical technique in treating esophageal carcinoma. Postoperative complications have been extensively reviewed, but literature focusing on intraoperative complications is limited. The main objective of this study was to report major intraoperative complications and 90-day mortality during MIE for cancer.

METHODS: Data were collected retrospectively from 10 European esophageal surgery centers. All intention-to-treat, minimally invasive laparoscopic/thoracoscopic esophagectomies with gastric conduit reconstruction for esophageal and GE junction cancers operated on between 2003 and 2019 were reviewed. Major intraoperative complications were defined as loss of conduit, erroneous transection of vascular structures, significant injury to other organs including bowel, heart, liver or lung, splenectomy, or other major complications including intubation injuries, arrhythmia, pulmonary embolism, and myocardial infarction.

RESULTS: Amongst 2862 MIE cases we identified 98 patients with 101 intraoperative complications. Vascular injuries were the most prevalent, 41 during laparoscopy and 19 during thoracoscopy, with injuries to 18 different vessels. There were 24 splenic vascular or capsular injuries, 11 requiring splenectomies. Four losses of conduit due to gastroepiploic artery injury and six bowel injuries were reported. Eight tracheobronchial lesions needed repair, and 11 patients had significant lung parenchyma injuries. There were 2 on-table deaths. Ninety-day mortality was 9.2%.

CONCLUSIONS: This study offers an overview of the range of different intraoperative complications during minimally invasive esophagectomy. Mortality, especially from intrathoracic vascular injuries, appears significant.
