Cyst of the canal of Nuck is a very rare female hydrocele, which is often caused by developmental disorders. The incidence of this disease is very low in the world, and misdiagnosis and missed diagnosis often occur due to insufficient understanding of it by clinical staff. We present these 2 case studies with the objective of enhancing awareness and comprehension of the disease, as well as offering valuable insights for its management and treatment.
A 38-year-old female patient was admitted to the hospital with a reversible mass in the left groin area that was painful during the menstrual period.A 50-year-old emergency patient who was admitted to the hospital for the discovery of an incarcerated mass in the left groin area for 2 hours.
In case 1, inguinal hernia was considered before operation, and the canal Nuck type I complicated with hernia was found intraoperatively.In case 2, cyst of the canal of Nuck was considered before operation, and the canal Nuck type Ⅲ was found intraoperatively.
In case 1, the patient was given tension-free hernioplasty combined with resection of a cyst of the round ligament of uterus. In case 2, the patient underwent transabdominal preperitoneal prosthesis plus cyst dissection of the round ligament of uterus.
In both patients, the mass in the groin area was completely removed and the pain caused by the mass disappeared.
These 2 cases emphasize that the possibility of hydrocele of the canal Nuck should be taken into account when discovering a female groin mass. Ultrasound, computed tomography, and magnetic resonance imaging are conducive to diagnosis, but the diagnosis also needs intraoperative findings and postoperative pathology. For this disease, surgical treatment is the first choice.For cyst of the canal of Nuck type I, transabdominal preperitoneal patch implantation is recommended. When cyst of the canal of Nuck type III is found under laparoscopy and it is difficult to simply use laparoscopic dissection, a small auxiliary incision can be made in the inguinal region to preserve the round ligament of the uterus and completely peel off the cyst.
努克管囊肿是一种非常罕见的女性鞘膜积液，通常由发育障碍引起。该病在全球发病率极低，临床工作人员对其认识不足，常导致误诊和漏诊。我们展示这2例病例研究的目的是提高对该疾病的认识和理解，并为其管理和治疗提供有价值的见解。
一名38岁女性患者因左腹股沟区有一可复性肿块且在月经期疼痛而入院。一名50岁急诊患者因左腹股沟区发现嵌顿性肿块2小时而入院。
病例1，术前考虑为腹股沟疝，术中发现为努克管I型合并疝。病例2，术前考虑为努克管囊肿，术中发现为努克管Ⅲ型。
病例1，患者接受了无张力疝修补术并切除子宫圆韧带囊肿。病例2，患者接受了经腹腹膜前补片植入术加子宫圆韧带囊肿切除术。
两名患者腹股沟区的肿块均被完全切除，肿块引起的疼痛消失。
这2例病例强调，发现女性腹股沟肿块时应考虑努克管鞘膜积液的可能性。超声、计算机断层扫描和磁共振成像有助于诊断，但诊断还需要术中发现和术后病理。对于这种疾病，手术治疗是首选。对于努克管I型囊肿，建议行经腹腹膜前补片植入术。当在腹腔镜下发现努克管Ⅲ型囊肿且难以单纯用腹腔镜切除时，可在腹股沟区做一个小的辅助切口，保留子宫圆韧带并完整剥离囊肿。
