ObjectiveToevaluatetheclinicalvalueoflaparoscopicrenalcystdecorticationandopencyst decortication surgery in the treatment of polycystic kidney disease.Methods Various clinical parameters were retro-spectively analyzed in 108 patients with polycystic kidney,include laparoscopic 60cases and open surgery 48cases.The observation indexes include operative time,operative bleeding,restoration time of bowel functions,postoperative drain-age volume,hospital time,postoperative complications,kidney function,blood pressure,and the clinical effects were estimated.Results In the laparoscopic group,the average operation time was (57.7 ±13.2) min,the average blood was (35.9 ±17.3)mL,the average time of exsufflation was (1.6 ±0.7)d,the average postoperative drainage volume was (23.2 ±4.3)mL,the average hospital time was (5.1 ±0.8)d.As compared with the open surgery group,the op-eration time,hospital stay,operative bleeding,postoperative drainage and hospital time of the laparoscopic group short-ened significantly(all P<0.05).The complication rate of the laparoscopic group and open surgery group were 5.0%and 16.7%separately.The complication incidence was significantly lower in the laparoscopic group than that in the open surgery group(P<0.05).At 3 months postoperative,the levels of serum creatinine(Cr),urea nitrogen(UN)and systolic blood pressure were obviously decreased compared with preoperative.There were no significant difference be-tween the two groups(P>0.05).The follow-up data showed that the cure rate and effective rate of the open surgery group were 81.2%and 18.8%,and the cure rate and effective rate of the laparoscopic group were 85.0% and15. 0%respectively.There were no significant difference of the clinical effects between the two groups (P >0.05). Conclusion The laparoscopic was superior to the open surgery in the operation time,hospital time,operative bleed-ing,postoperative drainage and hospital time.Laparoscopic renal cyst decortication in polycystic kidney is open surgery safer,little injury,quick recovery.Laparoscopic renal cyst decortication is safe and effective therapy,which can be used as primary surgical treatment for patients with polycystic kidney.

OBJECTIVE: To investigate the endoscopic and pathological characteristics of gastric adenomatous polyps and to assess the potential risk factors for canceration of gastric adenomatous polyps. METHODS: The endoscopic and pathological characteristics of the patients with gastric adenomatous polyps from January 1, 2005 to December 31, 2019 were summarized retrospectively, and the risk factors of canceration were analyzed. RESULTS: A total of 125 patients with gastric adenomatous polyps were included, 51.20% of whom were females. The average age was (66.7±12.3) years. 64.80% of patients with gastric adenomatous polyps equal or more than 65 years old, and only 5.60% of the patients less than 45 years old. Adenomatous polyps were mostly distributed in the corpus and antrum with 40.80% and 32.80%, respectively. The majority of them were single (90.40%) and sessile (76.81%). 65.4% of adenomatous polyps were no more than 1.0 cm in diameter, and 23.20% of patients with adenomatous polyps were combined with hyperplastic polyps and/or fundus glandular polyps, and 1.60% had both pathological types of polyps. 58.62% (17/29) patients with hyperplastic polyps and/or fundus glandular polyps had multiple polyps. 1.60% (2/125) of the patients had gastric neuroendocrine tumor of G1 stage. Synchronous gastric cancer was detected in 13.60% (17/125) of the patients with adenomatous polyps, and the proportion of low-grade intraepithelial neoplasia was 18.40% (23/125). The main types of synchronous gastric cancer were progressive (70.59%) and undifferentiated (66.67%). Chronic atrophic gastritis with intestinal metaplasia was found in 52.80% of the patients, and autoimmune gastritis accounted for 11.20%. The positive rate of Helicobacter pylori was 21.60%. The canceration rate of gastric adenomatous polyps was 20.80%. The cancer was mainly differentiated, but there was sigmoid ring cell carcinoma as well. Diameter of >1.0 cm (OR=5.092, 95%CI: 1.447-17.923, P=0.011), uneven surface morphology and erosion (OR=13.749, 95%CI: 1.072-176.339, P=0.044) were independent risk factors of adenomatous polyps. CONCLUSION The synchronous gastric cancer is common and the canceration of gastric adenomatous polyps is high with diameter and surface morphology as independent risk factors. We should pay attention to the identification of the pathological types of polyps and the evaluation of the whole gastric mucosa during the endoscopic examination.

Kaposi's sarcoma (KS) is an unusual vascular tumor associated with human herpesvirus-8 (HHV-8) infection, which is common in immunosuppressors. Although extremely rare, iatrogenic (drug-related) KS can occur in human immunodeficiency virus (HIV)-negative patients under immunosuppressive therapy. We report a 64-year-old male diagnosed with ulcerative colitis for 1 year. He was treated with methylprednisolone because of an acute severe disease flare. He presented with several popular violet lesions on the body 4 months after steroid therapy. Histological examination of skin biopsies showed Kaposi's sarcoma associated with HHV-8. The skin lesions regressed after steroid withdrawal and chemotherapy. Two key words "Kaposi's sarcoma" and "inflammatory bowel disease" were searched in Wanfang data and CNKI, but no relevant articles were found. Thirty-eight articles in English were retrieved on PubMed with the key words of ("ulcerative colitis" OR "Crohn's disease" OR "inflammatory bowel disease") AND (Kaposi sarcoma). Twenty-five cases of Kaposi's sarcoma related to inflammatory bowel disease (IBD) were reported. Including this case, the majority of 26 Kaposi's sarcoma related IBD patients were male (80.8%, 21/26). The average age was (51.1 ± 16.4) years. Twenty cases were ulcerative colitis and 6 were Crohn's disease. All the patients received immunomodulatory therapy, including glucocorticoid, azathioprine/mercaptopurine, methotrexate, cyclosporin and anti tumor necrosis factor α antibody. Thirteen cases were positive for HHV-8. There were 18 cases involving the distal ileum and colorectum only, 3 cases involving skin only, and 5 cases involving both skin and colorectum at the same time. Overall, the prognosis was good. Three patients only stopped immunosuppressive therapy, 1 received radiotherapy, 1 received chemotherapy, and 20 received surgery. Kaposi's sarcoma could be seen in IBD patients with immunomodulatory therapy. It is very important to distinguish from the skin lesions related to IBD or drug treatment. The adverse reactions of immunomodulatory therapy should not be ignored. In addition, attention should be paid to the cooperation of multi-disciplinary team, which can diagnose and treat rare cases earlier and more accurately.
