电视腹腔镜子宫切除术与阴式、腹式子宫切除术的临床评价

本文对腹腔境辅助阴式子宫切除术、阴式子宫切除术、腹式子宫切除术三组术式进行信床评价。每组10制，对其手术指征、腹腔镜组、腹式组以子宫肌瘤、卵巢肿瘤为主各为90％、100％，而阴式组则以子宫脱垂为主占100％(P值＜O．001)。腹腔镜组还能同时行胆囊切除术占30％。所切除子宫大小阴式组小于正常子宫占90％。而腹腔境组、腹式组均超过正常子宫大小(P＜0．001)。术后肠功能恢复在24h之内．腹腔镜组占100％、阴式组占80％、腹式组占20％(P＜0．001)。腹腔境组术后无需用镇痛剂。术后住院日腹腔镜组平均5天乏与腹式组平均7．3天比较。P＜0．001。得出腹腔镜辅助阴式子宫切除术兼阴式、腹式子宫切除术的优点。虽然出现2例非损伤性并发症．但只要仔细操作，该项手术在妇科手术领域有很大空间。     

超声造影技术在腹腔镜T1期肝细胞癌切除术中的应用价值

目的：探讨超声造影(CEUS)技术在腹腔镜T1期肝细胞癌(HCC)切除术中的应用价值。方法：选择2018年1月—2020年12月于天津医科大学第二医院行腹腔镜T1期HCC切除术的患者80例,根据是否行术前CEUS将患者分为造影组和对照组(每组40例)。均在距肿瘤边缘0.5 cm处切开患者肝脏实质并完整切除肿瘤,然后在切缘3个不同位置取组织活检。采用免疫组化检测癌组织中增殖细胞核抗原(PCNA)及Bcl-2相关X蛋白(Bax)的表达水平。记录患者手术时间、术中出血量、住院时间、肿瘤直径、切缘长度、术后进食时间、拔除引流管时间、术后最高丙氨酸氨基转移酶(ALT)和总胆红素(TBIL)及其恢复正常时间。术后均行规律随访观察。结果：与对照组相比,造影组手术时间(t=11.69,P<0.001)及住院时间更短(t=9.40,P<0.001),术中出血量更少(t=14.86,P<0.001);而两组患者在肿瘤直径(t=0.28,P=0.78)、切缘长度(t=0.18,P=0.86)、术后进食时间(t=0.44,P=0.66)及拔除引流管时间(t=1.16,P=0.25)方面差异均...     

Pregnancy following treatment of symptomatic myomas with laparoscopic bipolar coagulation of uterine vessels

BACKGROUND: Laparoscopic bipolar coagulation of uterine vessels (LBCUV) has been employed for women with symptomatic uterine myomas, but its effect on subsequent pregnancy has not been characterized. METHODS: Four-hundred and twenty-three women entered the study between March 1999 and December 2001. Of these, 142 women (33.6%) were under the age of 40 years at the time of LBCUV, 36 of whom (36/142, 25.3%) were sexually active without contraception. In a prospective study of 142 patients (<40 years old) undergoing LBCUV for symptomatic myomas, 15 women became pregnant (17 total pregnancies) and were evaluated by physical and ultrasound examinations. RESULTS: The volume of the dominant myoma was 117.4 +/- 118.4 and 36.8 +/- 56.8 cm(3) before and after LBCUV respectively. Volume of the dominant myoma after pregnancy was 46.2 +/- 76.7 cm(3) (mean +/- SD). There was a significant difference in myoma volume before and after LBCUV (P = 0.002), but no significant difference in myoma volume when comparing post-partum size with post-LBCUV size (P = 0.269). Pregnancy outcomes included seven miscarriages in the first trimester and one premature rupture of membrane (PPROM). Although the other pregnancies were regarded as uncomplicated, only two women were delivered of normal neonates as the other seven pregnancies were terminated secondary to patient request. CONCLUSIONS: The pregnancy and term pregnancy rates in sexually active women without contraception were 41.6% (15/36) and 5.6% (2/36) respectively. Because a relatively high rate (7/17, 41.2%) of early miscarriages was observed, we recommend that this procedure be employed only for women who do not desire additional children.     

Cystic duct and Heister's "valves"

The anatomy and physiology of the cystic duct have been relatively neglected by anatomists and the function of the spiral mucosal folds or "valves" of Heister, first described in 1732, remains obscure. The gross and microscopic anatomy of the cystic duct is reviewed together with results from laboratory investigations into the function of the cystic duct and its spirally arranged folds. The duct and spiral folds contain muscle fibers responsive to pharmacologic, hormonal, and neural stimuli. There is, however, no convincing evidence of a discrete muscular sphincter within the duct. Although the cystic duct is unlikely to play a major role in gallbladder filling and emptying, it appears to function as more than a passive conduit. Coordinated, graded muscular activity in the cystic duct in response to hormonal and neural stimuli may facilitate gallbladder emptying. The principal function of the internal spiral folds that are found in man and other animals may be to preserve patency of this narrow, tortuous tube rather than to regulate bile flow.

目的探析腹腔镜与传统手术治疗小儿腹股沟斜疝的临床效果。方法集合本院2016年1月-2019年9月期间接收小儿腹股沟斜疝(年龄<13周岁)234例,以实际治疗术式来分组,传统手术组201例,腹腔镜组33例,对比组行传统手术,腹腔镜组予以腹腔镜手术治疗,对比两组术中失血量、住院时间、初次下床活动时间、术后禁食时长、治疗费用,统计术后并发症并行组间对比。结果此次研究显示腹腔镜组术中失血量更少、术后禁食时长及初次下床活动时间更短(P<0.05),住院时间及、治疗费用组间对照中,腹腔镜组住院时间显著更短但治疗费用显著更高(P<0.05),术后并发症统计显示,腹腔镜组并发症发生率显著更低(P<0.05)。结论在小儿腹股沟斜疝治疗中腹腔镜手术虽费用较高,但患儿术后并发症更少,恢复更快,可优先选用。     

Robot-Assisted vs Laparoscopic Right Hemicolectomy in Octogenarians

ObjectiveWith increasing age, there is greater need for right-sided colonic resections than its left-sided counterparts. Older age is associated with limited physical and functional status, which carries greater operative risk. Improvements in robotic surgery questions its role, especially in older adults, compared with laparoscopy. The objective is to investigate whether robotic right hemicolectomy (RRH) is as safe and effective as laparoscopic right hemicolectomy (LHR) in octogenarians (age >80 years).DesignRetrospective cross-sectional analysis.Settings and ParticipantsOctogenarians who underwent elective RRH and LRH by the Tweed Colorectal Group over 5 years.MethodsComplications within 30 days, age, gender, smoking status, immunocompromised status, presence of diabetes, American Society of Anesthesiologists (ASA) physical status score, preoperative Eastern Cooperative Oncology Group (ECOG) performance status, mFI-5 (modified frailty index), operative time, method of anastomosis, postoperative length of stay (LOS), need for rehabilitation, and short-term oncologic data using the TNM criteria were compared using univariate and multivariate analysis.ResultsSeventy-eight elective patients were included. LRH and RRH groups had similar median ages, gender distribution, and comorbidities. Across the entire cohort, 61.5% had no 30-day complications. RRH had nonsignificantly shorter operative time but significantly shorter LOS (5 vs 8 days) and fewer minor complications (24.5% vs 34.5%). Major complications and overall complications were not significantly different between the groups. Lower ASA and ECOG status were associated with lower complication rates across both groups. Oncologic resection outcomes were similar for both approaches.Conclusions and ImplicationsRRH does not confer an increased risk of complications compared to LRH in the octogenarians and may be a viable alternative in the field of minimally invasive surgery for older patients. Future research should focus on intracorporeal anastomoses, as it is a potential confounder leading to the shorter inpatient LOS shown in our robotic group.
