ABSTRACT

Objective:To identify the risk factors for functional delayed gastric emptying(FDGE)after retroperitoneal tumor resection.Meth-ods:Sixty-seven patients with postoperative FDGE after retroperitoneal tumor resection from September 2017 to December 2022 admited in Peking University International Hospital were included in the observation group,and 836 normal patients who underwent ret-roperitoneal tumor resection during the same period were included in the control group.Medical histories and clinical treatment data were obtained for each group and compared to identify the risk factors for FDGE after retroperitoneal tumor resection.Results:The overall incid-ence of postoperative FDGE was 7.42%.Factors that were significantly elevated(P<0.05)in the observation group relative to the control group included adverse mental factors(37.31%),preoperative digestive tract obstruction(41.79%),postoperative abdominal cavity complic-ations(79.10%),diabetes(29.86%),average age of(61.85±6.11)years,and blood loss(1 011.94±507.30)mL.Pre-and post-surgery albumin levels[(38.22±3.75)g/L and(30.22±3.36)g/L,respectively]were significantly reduced(P<0.05)in the observation group compared to the control group.Risk factor analyses revealed that advanced age,diabetes,preoperative digestive tract obstruction,intraoperative blood loss,perioperative albumin level,postoperative abdominal cavity complications,and adverse mental factors were correlated with postoperative FDGE.Conclusions:Diverse factors could impact the risk of FDGE after retroperitoneal tumor resection.Patients should be accurately evalu-ated;reasonable and detailed prevention and treatment plans should be developed.

ABSTRACT

Objective:To explore the clinical diagnosis and treatment methods and curative effect of retroperitoneal ganglioneuromaMethods:The clinical data of 32 cases of retroperitoneal ganglioneuroma admitted to Peking University International Hospital from Apr 2015 to May 2022 were retrospectively analyzed, and their clinical characteristics, surgical efficacy and prognosis were discussed.Results:Of the 32 patients with retroperitoneal ganglioneuroma, 17 had no obvious clinical symptoms, 7 complained abdominal distension and pain, 6 had lower back pain, and 2 had abdominal mass. Tumors were located near the adrenal and renal regions in 18 cases, on both sides of the spine below the kidneys in 11 cases, and in the pelvis in 3 cases. tumors were single in 28 cases, multiple in 4 cases.Tumors were surrounded by major blood vessels in 12 cases. R 0 or R 1 resection was carried out in 27 cases, and palliative R 2 resection in 5 cases, combined organ resection in 6 cases, and piecemed resection in 8 cases. The maximum tumor diameter was (13.2±4.9)cm, the intraoperative blood loss was 500 (50-6 000 ml), and 6 cases suffered from major postoperative complications. Between patients with tumors encircling and encroaching major blood vessels or not, there were significant differences in age, intraoperative blood loss, R 2 resection rate, and pieceneal resection rate between the two groups ( t=2.44, P=0.021; Z=2.37, P=0.018; χ2=4.57, P=0.033; χ2=11.38, P=0.001). There was no recurrence in patients with R 0 or R 1 resection. Conclusions:The prognosis of complete resection of retroperitoneal ganglioneuroma is good .Major blood vessels encroachment of the tumor often leads to incomplente (R 2) resection.

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

Objective:To evaluate the clinicopathological features of primary retroperitoneal paragangliomas.Methods:Data of 24 patients with retroperitoneal paragangliomas who underwent surgical treatment in our hospital from Jan 2015 to Dec 2018 was collected and analyzed.Results:Hypertension, abdominal pain/discomfort and headache were the most common complaints while 10 patients were asymptomatic and were diagnosed accidently in routine body examination. Tumor size ranged from 3.4-13.0 cm (6.9±2.5) cm, and all the tumors were located in the vicinity of abdominal aorta and inferior vena cava. All the patients received surgical treatment. Intraoperative blood pressure fluctuations were significantly correlated with prolonged operation time, more blood loss, more blood transfusion and prolonged length of stay (all P<0.05). The median follow-up time was 29 months and 1 patient died from tumor recurrence and progression. The other patients have had a tumor free survival. Conclusions:Surgical resection was the principal treatment of primary paraganglioma. Preoperative assessment was very important for perioperative safety.

ABSTRACT

Objective:To investigate the pathogeny, diagnosis and treatment of solitary fibrous tumors of the abdomen and pelvis.Methods:Retrospective analysis was made on the clinical data of 12 SFT patients undergoing surgical resection in Peking University International Hospital from Jul 2015 to Jul 2019.Results:All patients underwent radical resection. After operation, complications in clued pelvic hemorrhage in 1 case and ureteral fistula in 1 case, all improved after conservative treatment.According to pathological and immunohistochemical results, 7 cases were MSFT and 5 cases were SFT. All patients were followed up for 2-53 months. 5 cases were recurrent, among which 1 case died of intestinal obstruction caused by tumor compression.Conclusion:The clinical manifestations of solitary fibrous tumors are mostly nonspecific.Imaging examination and puncture pathology are of great significance for preoperative diagnosis. Radical resection is an important means to improve the prognosis of patients.
