ABSTRACT
Objective:To investigate the effect of visceral obesity on the short-term curative effect of Da Vinci robotic-assisted radical resec-tion for rectal cancers.Methods:Clinical and pathological data of patients with rectal cancer undergoing Da Vinci robotic-assisted surgery,admitted to People's Hospital of Zhengzhou University and Cancer Hospital of Zhengzhou University from November 2019 to June 2022 were retrospectively analyzed.Visceral fat area(VFA)≥100 cm2 was used as the standard to define visceral obesity.Patients were categorized in-to visceral and non-visceral obesity groups.The short-term efficacy of the two groups was evaluated,and the influencing factors of post-operative complications were analyzed using univariate and multivariate Logistic regression.Results:Among a total of 169 patients,93 were included in the visceral obesity group and 76 in the non-visceral obesity group.There was no significant difference in the baseline data between the two groups(P>0.05).There was no conversion to laparotomy in the non-visceral obesity group,and the conversion rate was 1.1%(1/93)in the visceral obesity group.The second operation rate was 2.2%(2/93)in the visceral obesity group and 1.3%(1/76)in the non-visceral obesity group with no statistical difference between the two groups.There were no significant differences in the operation dur-ation,intraoperative blood loss,number of lymph node dissections,and total postoperative complication rate between the two groups(P>0.05).Multivariate Logistic regression analysis revealed that an NRS≥3 independently contributed as a risk factor for postoperative com-plications(OR=3.190,95%CI:1.240-8.210,P=0.016).Conclusions:An NRS≥3 is an independent risk factor for complications post-robotic rad-ical rectal cancer surgery.The robotic surgical platform can overcome obesity-related limitations and is equally safe and effective for pa-tients with visceral obesity presenting with rectal cancer.
ABSTRACT
Objective To investigate surgical techniques and curative effects of stereotactic operation in the treatment of cerebellopontine hemorrhage.Methods Ten cases of cerebellopontine hemorrhage were treated by using the model FY-98 Ⅱ stereotactic apparatus.Under the guidance of CT scanning,three-dimension coordinates of the target that was located at the center of the maximum section of the hematoma were calculated.Then a catheter was introduced into the target for aspiration and urokinase irrigation under the guidance of the stereotactic system.Results The operation was successfully completed in all the 10 cases.The operation time was 50~80 min(mean,60 min) and the intraoperative blood loss,25~40 ml(mean,30 ml).Postoperatively,3 fatal cases were encountered because of brainstem function failure or upper digestive tract bleeding.The remaining 7 cases survived after operation and were followed for 3~12 months(mean,8 months).The postoperative hospital stay was 16~30 days(mean,21 days).Assessment with the Activities of Daily Living(ADL) scale showed grade Ⅱ in 3 cases,grade Ⅲ in 2,Ⅳ in 1,and vegetative state in 1.Conclusions Stereotactic surgery in the treatment of cerebellopontine hemorrhage has advantages of accurate location,high reliability,and satisfactory effect.
