Objective To compare clinical outcome between 3D and 2D laparoscopic nephron sparing surgery for renal tumor. Methods Ninety patients who underwent laparoscopic nephron sparing surgery for renal tumor were collected. The patients were divided into 3D laparoscopic nephron sparing surgery (observation group) and traditional laparoscopic nephron sparing surgery (control group) according to the surgery method with 45 cases in each group. The operating time, renal warm ischemia time, blood loss, postoperative length of stay, hospitalization cost and rate of postoperative complications were compared between 2 groups. Results The operating time and renal warm ischemia time in observation group were significantly shorter than those in control group:(80.3 ± 10.7) min vs. (94.6 ± 18.5) min and (17.8 ± 3.1) min vs. (23.4 ± 4.7) min, and there were statistical differences (P<0.01 or 0.05). There were no statistical differences in blood loss, postoperative length of stay, hospitalization cost and rate of postoperative complications between 2 groups (P>0.05). Conclusions Compared with the traditional 2D laparoscopic technology, 3D laparoscopic technology has obvious advantage in spatial location and the sense of depth. To some extent, 3D laparoscopy reduces the operation difficulty, and shortens the operative time and renal warm ischemia time.

Objective To describe the ureteroplasty of congenital obstructive megaureter by laparoscopy and to evaluate the efficacy and feasibility of laparoscopic intervention for congenital obstructive megaureter. Methods Six patients with congenital obstructive megaureter were prepared for the laparoscopic surgery.The surgical procedure was briefly described as follows.The dilated ureter was dissected and cut off near the ureter orifice to the bladder by laparoscopy.Next,the free ureter was pulled out through the skin trocar site and was tailored as open surgery.After that,the ureter was placed back to the abdominal cavity and reimplanted laparoscopically into the bladder. Results The operation duration was 2 to 4 h (mean 2.4 h) and blood loss was very little (20~35 ml).No complication developed.The double J stent was removed at 3 months after the operation.Follow-up for half to 2 years showed that all the ureter drainage in the 6 cases was well without any infection. Conclusions Our preliminary result shows that laparoscopic surgery is a safe and effective method for treatment of megaureter.

Objective To study the anatomical feature s of the retroperitoneal cavity around kidney under laparoscope and to provide ana tomical guidance for laparoscopic surgery. Methods Lapar oscopic renal and ureteral operations were performed on 241 patients (145 men an d 96 women; age range,16-75 years;mean age,45.3 years).Through the videos and ph otographs of these operations,the anatomical features were analyzed.The atlas wa s drawn and surgical access was designed. Results Under laparoscope lateral conal fascia continues from the fascia of quadratus lumborum at its lateral border.This fascia covers posterior lamella of Gerota’s fascia and fuses into transversalis fascia beneath peritoneum. Fusion fascia lies befor e anterior lamella of Gerota’s fascia. It extends laterally and disappears grad ually to the lateral reflexion of peritoneum.The plane between fusion fascia and anterior lamella of Gerota's fascia, the plane between lateral conal fascia and posterior lamella of Gerota’s fascia, the plane before the quadratus lumborum and psoas major, are all vessel-free planes.Lateral border of colon,peritoneum and fusion fascia form a triangle lateral to colon.Fusion fascia,lateral conal f ascia and Gerota’s fascia form a vessel-free triangle. Conclusions Dissection through the vessel-free planes prevents laparoscopic op erations from bleeding and organ injury.Full understanding of the laparoscopic a natomical features of the retroperitoneal cavity around kidney provides the anat omic theoretical basis for laparoscopic operations.

Objective To analyze the epidemiologic data of patients withClostridium botulinum food poisoning, and to improve the understanding, diagnosis and treatment of food borne botulism.Methods A retrospective study was conducted. Fifty-three patients withClostridium botulinum food poisoning admitted to Chinese PLA Center of Poisoning and Treatment from January 2009 to December 2016 were enrolled, and they were divided into mild, moderate, and severe groups according to the severity of disease. The clinical data including medical history, epidemiology data, routine blood test and blood biochemistry at hospital admission, the vital signs and arterial blood gas analysis before and after treatment, as well as the occurrence frequency of symptom and sign on set were collected.Results Fifty-three patients with food borne botulism were enrolled, with 33 patients in mild group, 13 in moderate group, and 7 in severe group. Most of the patients were female, the age distribution was in large span, the outbreak of disease was in groups mainly with the family, and patients were mainly located in Hebei Province, Beijing and Henan Province. The outbreaks were mainly happened in Spring and Summer, and homemade fermentation products were still the first cause of poisoning with the average latent period of (51.01±4.78) hours. The majority of patients with botulism were in mild resulted from the type A toxin. With the aggravation of disease, hospitalization time was gradually increased, white blood cell (WBC) and neutrophils (NEUT) at hospitalization admission, and respiratory rate (RR), heart rate (HR), fraction of inspired oxygen (FiO2) before the treatment were shown in obviously rising trend, albumin (ALB) at hospitalization admission and pH, arterial partial pressure of oxygen (PaO2), arterial oxygen saturation (SaO2) before treatment were in decline. The parameters in severe group were most severe, and had significant differences as compared with those of mild group [hospitalization time (days): 72.57±39.52 vs. 6.61±3.72, WBC (×109/L): 13.01±6.44 vs. 6.85±2.07, NEUT: 0.85±0.07 vs.0.63±0.14, RR (bpm): 32.14±4.33 vs. 15.18±1.70, HR (bpm): 132.29±5.19 vs. 75.54±8.24, FiO2: 0.32±0.05 vs. 0.21±0.00, ALB (g/L): 38.57±4.65 vs. 42.09±4.57, pH: 7.08±0.10 vs. 7.38±0.07, PaO2 (mmHg, 1 mmHg = 0.133 kPa): 75.16±5.24 vs. 98.39±1.50, SaO2: 0.78±0.06 vs. 0.97±0.02, allP < 0.05]. The symptom and sign on set of 53 patients with food borne botulism was dizziness, followed by fatigue, blurred vision, nausea, and other symptoms and signs were lower than 50%, and the occurrence of dizziness with rank one happen rate was significantly higher than blurred vision and nausea (χ2 values were 7.209 and 10.502 respectively, andP values were 0.007 and 0.004 respectively). After the on time prescription of botulinum antitoxins treatment, the clinical symptoms of patients could be relived quickly. All the patients were discharged without deaths.Conclusion In order to improve the recovery of the food borne botulism poisoning patients, adequate antitoxin and the related organ supports should be prescribed on time.
