3. Treatment strategy for gastrointestinal tumor under the outbreak of novel coronavirus pneumonia in China
Chinese Journal of Gastrointestinal Surgery 2020;23(2):I-IV
The outbreak of the novel coronavirus pneumonia (NCP) has become a public health emergency in China. Chinese authorities and health agencies had devoted great efforts to control this disease. As surgeons specialized in the treatment of gastrointestinal tumors, we should always be aware of the prevention for NCP and incorporate this awareness into every detail of clinical practice. For the patients with gastrointestinal tumors, pre-admission screening should be done in order to rule out NCP. Real-time RT-PCR panel and chest CT scan should be conducted for patients with fever (>37.3℃), travel history to Hubei Province within 14 days, or contact history with residents from Wuhan district within 14 days. Prevention measures for both medical staffs and the screen-negative admitted patients should also be enhanced because false negative is possible. Medical instruments should be properly discarded or disinfected according to standardized procedures established by the local center for disease control and prevention (CDC). Surgical operation should be reduced at a minimal level to prevent cross infection in this special period.Surgical intervention for benign tumor should be postponed. For malignant tumor, multidisciplinary therapy (MDT) is recommended and non-surgical anti-tumor therapy should be selected with higher priority. Neoadjuvant therapy is highly recommended for gastrointestinal cancer at advanced stages that meet the indications of NCCN guideline (gastric cancer T stage ≥ 2/rectal cancer T stage ≥ 3/unresectable colon cancer). Gastric or esophagogastricjunction (EGJ) malignant tumor with obstruction can be managed with gastric tube decompression or stent placement to relieve the symptoms. Transnasal enteral feeding tube intubation/percutaneous endoscopic gastrostomy could be adopted to ensure enteral nutrition supply. For colorectal malignancy with simple intestinal obstruction, stent placement can achieve a high success rate, which not only helps avoid emergency surgery, but also creates a better condition for subsequent surgery. Transcatheter arterial embolization for hemostasis is an alternative choice for gastrointestinal tumor with bleeding. However, emergency operation still must be performed for patients with acute uncontrolled bleeding, obstruction or after other alternative treatment measures fail. All cases with suspicious or confirmed with NCP must be reported to the local CDC department. All invasive intervention must be performed in a designated isolation area. Tertiary prevention measure must be adopted for all anesthetists with additional face mask or medical goggle protection to prevent respiratory droplet transmission. Preventive enterostomy is preferable in lower digestive tract surgery. Thoroughly disinfecting the operating room after surgery is necessary. Fever after surgery must be carefully differentiated whether it's caused by post-surgery abdominal infection/inflammation or NCP. Single-room isolation and related examinations should be performed according to the standard procedures. We believe that with the unprecedentedly joint efforts of doctors and patients, we will eventually win this war against NCP.

OBJECTIVETo describe and analyze the complications of subcutaneous venous access port for patients with gastrointestinal malignancy.
METHODSData of 1 912 patients with gastrointestinal malignancy who accepted chemotherapy in our department via subcutaneous venous access ports, including 127 cases in upper arm, 865 cases in subclavicular vein and 920 cases in internal jugular vein, from June 2007 to April 2016 were analyzed retrospectively. Associated complications and risk factors were emphatically investigated.
RESULTSPostoperative complications were confirmed in 233 patients(12.2%), and complication morbidity was 37.0%(47/127), 15.5%(134/865), 6.7%(62/920) in upper arm group, subclavicular vein group, internal jugular vein group respectively, whose difference was statistically significant (χ=71.060, P=0.000). Sixty-one(3.2%) patients developed early complications (in the day of insertion, including catheter dislocation, pneumothorax, arterial damage). Early complication morbidity of upper arm group (14.2%, 18/127) was higher as compared to subclavicular vein group (3.4%, 29/865) and internal jugular vein group(1.5%, 14/920) with significant difference (χ=57.867, P=0.000). Postoperative long-term complications (catheter dislocation, thrombosis, pinch-off syndrome, infusion base exposure, catheter detachment) were found in 182(9.5%) patients. Morbidity of long-term complication was 5.2%(48/920) in internal jugular vein group, which was significantly lower than 22.8% (29/127) in upper arm group and 12.1% (105/865) in subclavicular vein group with statistically significant difference (χ=50.828, P=0.000). Multivariate analysis indicated that subclavicular vein intubation (OR=0.536, 95%CI: 0.341 to 0.843; P=0.007 OR=0.156, 95%CI: 0.096 to 0.253, P=0.000), internal jugular vein intubation (OR=0.156, 95%CI: 0.096 to 0.253, P=0.000), operation time <40 minutes (OR=0.458, 95%CI: 0.342 to 0.613, P=0.000) and standardized training (OR=0.233,95%CI: 0.171 to 0.318, P=0.000) were protective factors of postoperative complication; besides, subclavicular vein intubation (OR=0.458, 95%CI: 0.342 to 0.613, P=0.000), internal jugular vein intubation (OR=0.233, 95%CI: 0.171 to 0.318, P=0.000) and standardized training (OR=0.313, 95%CI: 0.173 to 0.568, P=0.000) were protective factors of thrombosis.
CONCLUSIONSSubcutaneous venous access port implantation is a preferable access to central vein. Appropriate intubation approach and standardized training may reduce postoperative complications effectively. Internal jugular vein approach is safer and more reliable than upper arm vein and subclavian vein approach.
