Adult groin hernias

A groin hernia is a common presenting complaint for adults and surgical repair is usually recommended. Patients may present with swelling or pain in the groin and one should be cognisant of the surgical emergency of a strangulating or obstructing hernia. A careful history and examination will help determine differential diagnoses and with planning the potential approach for repair. Surgical techniques have developed in recent years with a swing towards favouring laparoscopy in the elective patient. For both open and laparoscopic approaches, there are recognized techniques to consider. It is crucial to have a clear understanding of the anatomy in order to develop the skills required for accurate dissection, reduction and repair. Complications, although rare, can lead to severe morbidity. Laparoscopy has the advantage of reducing postoperative chronic pain but requires greater skill and experience to perform successfully. This chapter outlines the key considerations and surgical techniques for groin hernia repair and should be used in conjunction with practical training.

超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌根治术中的应用

目的:研究超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌根治术中的应用价值。方法:选取90例择期进行腹腔镜结直肠癌根治术患者作为研究对象，随机分为观察组和对照组，各45例。对照组采用传统腰麻联合丙泊酚麻醉，观察组采用超声引导下腰方肌阻滞联合丙泊酚麻醉，比较两组患者术中（麻醉后5、15、30、60 min）收缩压（SBP）、舒张压（DBP）、心率（HR）和术后不同时间段的疼痛评分（VAS评分），以及加用镇痛药情况和肠道恢复排气时间和术后48 h内不良反应发生情况。结果:两组患者SBP、DBP、HR组间、不同时间点及交互差异均有统计学意义（P<0.05），且观察组麻醉后上述指标波动较对照组小（P<0.05）；麻醉前，两组患者皮质醇、肾上腺素水平无显著差异（P>0.05），麻醉后各时间点观察组患者上述指标水平均显著低于对照组（P<0.05）；两组患者VAS评分组间、不同时间点及交互差异均有统计学意义（P<0.05），且观察组术后各时间点VAS评分均显著低于对照组（P<0.05）；观察组不良反应发生率显著低于对照组（8.89% vs 24.44%, P<0.05）；观察组患者加用镇痛药的人数、剂量和肠道恢复排气时间均显著少于对照组（P<0.05）。结论:超声引导下腰方肌阻滞联合丙泊酚麻醉在腹腔镜结直肠癌手术中具有良好、稳定的麻醉效果，可有效缓解患者疼痛，减少术后不良反应发生。     

Outcomes of robot-assisted partial nephrectomy for completely endophytic renal tumors: A multicenter analysis

IntroductionMulticenter retrospective analysis of robotic partial nephrectomy for completely endophytic renal tumors (i.e. 3 points for the ‘E’ domain of the R.E.N.A.L. nephrometry score) was performed.Materials and methodsPatients’ demographics, tumor characteristics, perioperative, functional, pathological and oncological data were analyzed and compared with those of patients with exophytic and mesophytic masses (i.e. 1 and 2 points for the ‘E’ domain, respectively). Multivariable logistic regression analysis was used to assess variables for trifecta achievement (negative margin, no postoperative complications, and 90% estimated glomerular filtration rate [eGFR] recovery).ResultsOverall, 147 patients were included in the study group. Patients with a completely endophytic mass had bigger tumors (mean 4.2 vs. 4.1 vs. 3.2 cm; p < 0.001) on preoperative imaging and higher overall R.E.N.A.L. score. There was no difference in mean operative time. Estimated blood loss was higher in the endophytic group (mean 177.75 vs. 185.5 vs. 130 ml; p = 0.001). Warm ischemia time was shorter for the exophytic group (median 16 vs. 21 vs. 22 min; p < 0.001). Postoperative complications were more frequent in patients with endophytic tumor (24.8% vs. 19.5% vs. 14.8%; p < 0.001). Six (4.5%) patients had positive surgical margins, there was no difference between groups. Trifecta was achieved in 44 patients in endophytic group (45.4 vs. 68.8 and 50.9%, p < 0.001). Multivariable analysis for trifecta revealed that clinical tumor size (odds ratio: 0.667, 95% confidence interval: 0.56–0.79, p < 0.001) was only significant predictor for trifecta achievement.ConclusionsOur findings confirm that RAPN in case of completely endophytic renal masses can be performed with acceptable outcomes in centers with significant robotic expertise.     

Proseal喉罩在妇科腹腔镜手术麻醉中的应用研究

目的探究分析Proseal喉罩在妇科腹腔镜手术麻醉中的具体应用和临床价值。方法此项研究的考察对象为本院妇科于2017年7月—2019年7月期间医治的80名腹腔镜手术患者,经随机方式把这些患者归入参照组(n=40)、试验组(n=40)。前者在手术麻醉中安排气管插管,试验组患者在手术麻醉中安排Proseal喉罩,对比两组腹腔镜手术患者的生命体征(心率HR、平均动脉压MBP)的变化、术中并发症发生率和术后不良反应率。结果试验组腹腔镜患者插罩前和取罩后的生命体征无明显变化,差异无统计学意义(P>0.05),对照组患者插管前和拔管后的生命体征有明显变化,且试验组患者的术中并发症发生率与术后不良反应率相较参照组皆偏低(P<0.05)。结论Proseal喉罩在妇科腹腔镜手术麻醉中的应用相对于气管插管具有更高的稳定性和安全性,能够保证患者血流动力学平稳,且并发症的发生率更低。     

Gastric volvulus and giant Bochdalek hernia in an adult patient that were safely repaired by endoscopic reduction and elective laparoscopic surgery

A Bochdalek hernia (BH) is a congenital abnormality with incomplete closure of the diaphragm. It is usually manifested in infants but rarely in adults. Here, we report an adult patient with gastric volvulus and giant BH that were safely repaired by endoscopic reduction and elective laparoscopic surgery, respectively. A 79-year-old woman presented with left upper abdominal pain but no history of trauma. CT revealed a giant BH with gastric volvulus. After emergency endoscopic reduction of the volvulus, elective laparoscopic repair of the BH was performed. The 8 × 8-cm defect was repaired with interrupted nonabsorbable sutures and a mesh. The patient's postoperative course was uneventful, and no complications or recurrence were observed in the 6 months that followed.     

Laparoscopic surgery for familial multiple gastrointestinal stromal tumors with germ line c-kit gene mutation

Familial gastrointestinal stromal tumor (GIST) is an exceedingly rare disease characterized by mutations in the c-kit and platelet-derived growth factor receptor alpha genes. We report the case of a 73-year-old woman with multiple submucosal tumors (SMTs) in the stomach and small intestine. Her elder sister had previously presented with multiple SMTs on examination and underwent surgery to remove the tumors because they showed a tendency to increase in size during follow-up. The sister's tumors were pathologically diagnosed as GISTs, and a germ line mutation was recognized in exon 17 of c-kit. Subsequently, the patient presented with multiple SMTs and the same germ line mutation as her sister. After 9 years of follow-up, a single tumor was found to have grown in size, and SILS was performed for this SMT, which was also pathologically diagnosed as a GIST. To our knowledge, this is the first report of laparoscopic surgery for a case of familial GIST.
