ABSTRACT
Objective:To summarize the experience of surgical treatment of pelvic retroperitoneal neoplasms.Methods:A total of 107 patients with pelvic retroperitoneal neoplasms underwent surgical treatment from Apr 2015 to Sep 2020. According to the neoplasm location, size, and the relationship with the surrounding tissues, individualize the surgical plan, analyze the patient's basic condition, bleeding volume, tumor size, whether it is the first operation,or combined organ resection, etc.to find out the relevant factors affecting the surgical complications.Results:The surgical route included anterior approach in 67 cases , sacrococcygeal approach in 21 cases, combined abdominal-sacral approach in 13 cases, and laparoscopy in 5 cases. Twenty-nine patients underwent combined organ resection, postoperative complications occurred in 27 patients including colorectal anastomotic leakage in 6 cases, urinary fistula in 6 cases, delayed pelvic floor healing in 6 cases, rectovaginal fistula in 3 cases, and postoperative bleeding in 2 cases. The statistical analysis show whether or not first operation is related to the occurrence of complications ( χ2=4.79, P<0.05) Conclusion:Pelvic retroperitoneal neoplasms need to be fully prepared before surgery and individualized design. Intraoperative combined bleeding control measures and combined organ resection can effectively increase the resection rate and ensure the safety of surgery.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the method and effect of percutaneous nephroscopic necrosectomy (PNN) for post-operatively resident infection of severe acute pancreatitis (SAP).</p><p><b>METHODS</b>Data of the 15 SAP patients with post-operatively resident infection treated by PNN from June 2008 to December 2014 in Chinese People's Liberation Army General Hospital were reviewed. Twelve of the patients underwent the laparotomy within 1 week, 1 in 3(rd) week, 1 in 4(th) week and the other one on the 127(th) day. All of the referrals firstly received (multi-)percutaneous catheter drainage (PCD), and then PNN operation according to the disease, followed by continuous irrigation-drainage.</p><p><b>RESULTS</b>Eleven patients were healed after received only one PNN operation, 2 patients for twice, 1 for three times and 1 for four times. The average post-operative time of hospital stay was 66.2 days (10-223 days). The complications after operation contained colon fistula (n = 1), abdominal hemorrhage (n = 1), pancreatic pseudocyst (n = 1), severe pulmonary infection (n = 1). Three patients eventually died.</p><p><b>CONCLUSIONS</b>Percutaneous nephroscopic necrosectomy is a minimally invasive approach which could prevent the complicated re-laparotomy operation, result in less complication. It is an ideal method for treating SAP patients with post-operatively resident infection.</p>
