Computer tomography-guided negative pressure drainage treatment of intrathoracic esophagojejunal anastomotic leakage:A case report

BACKGROUND Esophagojejunal anastomotic leakage(EJAL)is a serious and potentially crucial complication of total gastrectomy and represents the major cause of postoperative death,with a mortality rate of up to 50%.However,treatment remains challenging and controversial.We report here the case of a patient whose intrathoracic EJAL was successfully treated with computer tomography(CT)-guided negative pressure drainage treatment.CASE SUMMARY A 69-year-old male patient complained of difficulty swallowing within the last six months.He was diagnosed with esophagogastric junction carcinoma,Siewert II,cT3N0M0 stage II.Total gastrectomy and Roux-en-Y esophagojejunostomy were performed.High fever,left chest pain and dyspnea appeared on postoperative day 5,and EJAL was confirmed by CT,gastroscopy and oral blue-dimethylene tests.Conservative treatment measures were applied immediately,including antibiotics,nasojejunal tubes,and repeated thoracic puncture and drainage under ultrasound guidance.However,without sufficient and effective drainage,the thoracic infection and systemic condition continued to deteriorate.With the cooperation of multiple departments,percutaneous CT-guided drainage(24 Fr 7 mm)in the thoracic cavity was successfully placed near the anastomotic leakage.Because of continuous negative pressure suction,the infection symptoms were effectively controlled and the general situation gradually recovered.Subsequent follow-up examination showed that the patient was in good condition.CONCLUSION Negative pressure drainage via CT may represent an effective minimally invasive approach to treating intrathoracic EJAL.

Choice and management of negative pressure drainage in anterior cervical surgery

BACKGROUND Postoperative unobstructed drainage is an important measure for avoiding hematoma formation and preventing complications from anterior cervical surgery.AIM To discuss the characteristics and key points of clinical management of two types of commonly used negative pressure drainage systems in clinical settings.METHODS Two types of commonly used silica gel negative pressure drainage balls and a type of gastrointestinal decompression apparatus were fully emptied and then injected with different amounts of water and air.Following this,the negative pressure values of the three devices were measured.Meanwhile,we undertook a retrospective analysis of the clinical data of 1328 patients who had been treated with different negative pressure drainage apparatuses during their anterior cervical surgery in our department between January 2007 and January 2018.RESULTS As the amount of injected air or water increased,the negative pressure of the silica gel negative pressure drainage ball decreased rapidly,dropping to zero when 150 mL of water or air was injected.In contrast,the negative pressure of gastrointestinal decompression apparatus decreased slowly,maintaining an ideal value even when 300 mL of water or air was injected.And statistical analysis demonstrated that patients who had been treated with the gastrointestinal decompression apparatus were less likely to develop severe complications than those who had been treated with the silica gel negative pressure drainage ball(P<0.05).CONCLUSION This study showed that the gastrointestinal decompression apparatus has the advantages of large suction capacity,long duration of continuous negative pressure,and good drainage effect,all of which are the favorable factors for the use of this apparatus for negative pressure drainage in anterior cervical surgery.

A New Technique for The Therapy of Complicated Deep Tissue Infection(with 4 Cases)

Objective: The objective of this study was to discuss the effect of double perfusion cannula accompanied with low negative pressure drainage in the treatment of complexity of abdominopelvic and perineal infections. Methods: The technology of the double perfusion cannula accompanied with low negative pressure drainage was used to treat complexity of abdominopelvic and perineal infections. Results: Double perfusion cannula accompanied with low negative pressure drainage can be applied to the treatment of complexity of abdominopelvic and perineal infections. It has an obvious effect on infection control and reduces recovery time. Conclusion: Double perfusion cannula accompanied with low negative pressure drainage has a good effect on complexity of abdominopelvic and perineal infections; it can be used in wider surgical fields to prevent infections.
