Sliding appendiceal inguinal hernia with a congenital fibrovascular band connecting the appendix vermiformis to the right testis

It is not uncommon to find the appendix vermiformis within a hernia sac; however, sliding appendiceal inguinal hernia is rare. A 9-month-old boy with an incarcerated right scrotal hernia is presented in this case report. Although the hernia was reduced through a conservative approach, appendix vermiformis remained in the hernia sac because of its attachment to the upper pole of the right testis. Exploratory surgery during the inguinal hernia repair revealed a connecting band that extended from the appendix vermiformis into the scrotum and attached to the right testicle. Histologic examination showed that the band was congenital. After reduction of an incarcerated hernia, the persistence of a thickened or a cord-like structure is a warning for the presence of a sliding hernia. We suggest that this uncommon developmental anomaly is likely to cause the processus vaginalis to remain patent, thus facilitating hernia formation. Electronic Publication     

An inguinal hernia with cryptorchidism with a Leydig cell tumor in an elderly man: A case report

IntroductionCryptorchidism is common in children but is rare in the elderly. It often presents with a constellation of signs and symptoms similar to routine inguinal hernias. We present the case of an elderly man with cryptorchidism containing a Leydig cell tumor and provide clinical insights.Presentation of caseAn-84-year old man was admitted with an incarcerated right lower quadrant hernia. Both testes were absent on palpation of the scrotum. After reduction of the hernia, computed tomography scan revealed a round lesion in the hernia sac, which was suspected to be the ectopic testis. Laparoscopic exploration was performed in combination with an open anterior approach. The hernia orifice was the right internal inguinal ring, and the inguinal canal was obliterated by adhesions because the spermatic cord did not pass through it. The ectopic testis was resected with the hernia sac, and the hernia repaired with a KUGEL™ patch (Bard, USA).DiscussionLaparoscopic exploration was useful to delineate the anatomy of this unusual inguinal hernia. The open anterior approach was necessary to dissect the ectopic testis and the hernia sac. Pathological findings revealed tumor cells with clear cytoplasm in the resected testis, diagnosed as a Leydig cell tumor.ConclusionThe combination of laparoscopic and anterior approaches facilitated the surgical treatment of an unusual inguinal hernia with cryptorchidism. The resected ectopic testis should undergo thorough histopathologic examination.     

A case of 46, XY DSD presenting as a crossed ectopic gonad with a contralateral sliding inguinal hernia

A three-month-old boy was referred to our facility for the treatment of a right impalpable testis, left inguinal hernia, and penoscrotal hypospadias with asymmetric external genitalia. The left gonad was palpated in the left scrotum. The chromosomal study revealed a normal male 46, XY karyotype. Operative findings showed that the right streak gonad, uterus, and fallopian tubes were in the wall of the left hernia sac, forming a sliding hernia. Laparoscopy confirmed that the right gonadal vessels had crossed to the left internal inguinal ring. Herniorrhaphy was done and the right streak gonad, uterus, and fallopian tubes were excised. An exploration of the left gonad revealed an ovotestis. The ovary was removed, and a left testicular biopsy was simultaneously performed. A one-stage hypospadias repair using Koyanagi procedure was also performed. The pathological findings showed an ovarian stroma in the right gonad and left ovary. Only Sertoli cells were detected in the biopsied specimen from the left testis.     

Epidermoid cyst of the scrotum: report of a case

A 61-year-old male visited our hospital with the chief complaint of a mass in the right scrotum on October 4, 1985. Under the diagnosis of intrascrotal tumor, the mass was resected surgically. It was a subcutaneous tumor, and had no relation to any intrascrotal organ, such as testis, epididymis or spermatic cord. The mass was 7 x 6 x 5 cm. Pathological diagnosis was epidermoid cyst of the scrotum. Epidermoid cyst of the scrotum is a rare disease and only 7 cases have been reported in Japan.     

Left Acute Scrotum Associated with Appendicitis

A 10-year-old boy, who had a mild inguinal hernia in his left scrotum, was referred to our clinic because of redness of the scrotal skin and tenderness of the left scrotal contents. Scrotal echography showed a hypoechoic lesion around the normal testis and epididymis. Because torsion of either the testis or testicular appendage was suspected, the scrotum was opened and 1.5 mLof purulent fluid was observed in the tunica vaginalis with inflammatory tissue around the testis and epididymis. On the first postoperative day, a low grade fever and abdominal tenderness persisted, however, the abdomen was flat and soft. There was no marked tenderness over McBurney's point, butthere was moderate tenderness over Lanz's point on deep palpation. Abdominal sonography and magnetic resonance imaging revealed abscess formation between the bladder and the sacrum. With a diagnosis of perforation of the appendix, a laparotomy was performed. The inguinal hernia sac could not be observed on inspection, and it was not possible to palpate the left side because of severe adhesion due to infection. Also, the neck of the right inguinal sac could not be seen. The appendix specimen was gangrenous. On the second postsurgical day, all symptoms and signs disappeared. We present this rare condition and discuss the difficulty in establishing a diagnosis.     

A case of hernia uteri inguinalis with a left crossed ectopic testis

A 70-year-old man with the complaint of dysuria and painless swelling of the right scrotal sac and inguinal region was operated on for suspected right inguinal hernia. The hernia sac contained two testis and immature uterine tissue, which were pathognomonic of left crossed ectopic testis complicated by hernia uteri inguinalis. The chromosomes were normal. Statistics on 57 similar cases indicated that this was the eldest of all such patients reported in Japan; since he had two children, he seems to have been fertile.     

A case of giant obsolete hydrocele testis

A 58-year-old man visited the urological clinic in Prefectural Tohkamachi Hospital with complaint of swelling of bilateral scrotal contents. He had no history of fever, pain or difficulty of urination. Physical examination revealed a giant mass of adult-head size in right scrotum and left inguinal hernia of fist growth. Surgical extirpation of the right scrotal mass and left inguinal herniorrhaphy was performed and the mass was diagnosed as obsolete hydrocele testis and weighed 1,600 g. The excised hydrocele sac showed marked thickening and dark brown pus amounted to about 1,400 ml, which was negative in bacterial culture. Histological examination revealed partial deposits of cholesterol and calcification in tunica vaginalis with extremely atrophic testis and destructive spermatogenesis. The findings suggested the existence of long-term infection in hydrocele testis. The etiology and pathogenesis of this disease is discussed.     

Intraparietal (interstitial) hernia. A rare variety of a common condition

Summary A rare variety of intraparietal hernia is described in a five-months-old boy. It was an extension of a right inguinal hernial sac with undescended; testis. The sac passed upwards and laterally between the external oblique aponeurosis and the internal oblique muscle. The patient was treated surgically by excision of the hernial sac and the right undescended testis fixed in a subdartous pouch. The baby was discharged from hospital in good condition.     

Report of a 45, X male with monoorchism and distal hypospadias

We present the rare case of a 5-year-old boy with a 45, X karyotype. The boy's family pedigree analysis was unremarkable. On admission, he was 97.4 cm tall (2.0 SD below normal references) and weighed 13.9 kg (1.0 SD below normal references). Mild mental retardation was suspected on the PPVT scale. Physical examination revealed a well-developed penis with subglanular hypospadias. His left testis was located well down at the bottom of the scrotum and the right testis was impalpable. Unilateral testicular agenesis and persistence of müllerian remnants within the hernia sac were noted on the previous records of inguinal exploration on the right side. The left testis was biopsied through a scrotal incision and prepubertal testicular tissue was confirmed. No ovary was found on laparotomy exploration. Hypospadias was repaired with meatal advancement and glanuloplasty (MAGPI) urethroplasty. His postoperative course was uneventful. Our report represents a rare case of a boy with a 45, X karyotype. Current theories for testicular development were reviewed.

Influence of the hernia sac treatment method on the occurrence of seroma after laparoscopic transabdominal preperitoneal hernia repair

PurposeTo determine whether transection of the hernia sac during laparoscopic transabdominal preperitoneal hernia repair (TAPP) affects the occurrence of seroma, and to explore the risk factors for seroma.MethodsIn total, 330 consecutive male patients with indirect inguinal hernia who underwent TAPP repair at the Qingdao University Affiliated Hospital from January 2020 to June 2021 were retrospectively enrolled in this study. According to the intraoperative hernia sac treatment, patients were divided into a completely reduced sac group and a transected sac group.ResultsAmong the 330 inguinal hernia male patients, 240 received hernia sac reduction and 90 received hernia sac transection. Fifty-four patients developed seroma, with an incidence of 16.4%. In patients with a hernia defect measuring ≥3 cm and extension into the scrotum, the difference in the incidence of seroma between the two treatment groups approached significance (P = 0.052). The risk factors for seroma, high body mass index, hernia sac ≥3 cm, extension of the hernia into the scrotum and operation time were significantly associated with postoperative seroma.ConclusionThis study showed that the incidence of seroma after TAPP was as high as 16.4%. For patients with a hernia sac that is too large and descended extends into the scrotum, transection may be better than complete dissection of the hernia sac and preventive measures should be taken for patients with high body mass index, hernia sac measuring ≥3 cm, and a high risk of the hernia extending into the scrotum.     

Perforated caecal diverticulum as a content of inguinal hernia — report of a rare case

A tablet induced perforation of a caecal diverticulum into a hernial sac is a rare happening. The report discusses the presentation and outcome of a patient with such an unusual disease. A 55-year-old man presented with features of irreducible right sided indirect inguinal hernia. A hard swelling near upper pole of right testis was noted. Scrotal ultrasound revealed a normal testis. At operation caecum and proximal ascending colon were found in the hernial sac with the caecum adherent to the testis. As caecal malignancy could not be ruled out and enbloc Rt Haemicolectomy with Rt orchidectomy was performed. The patient had an uneventful recovery. Pathological examination of the specimen revealed a perforated caecal diverticulum with presence of multiple tablets in its lumen invaginating the upper pole of right testis without any evidence of malignancy. Tablet induced perforation of a caecal diverticulum into a hernial sac is a rare clinical entity. If malignancy cannot be negated at operation, a right haemicolectomy is a safe and feasible option.     

Tunica albuginea cyst: a case report]

A 47-year-old male visited our hospital complaining of painless swelling of the right scrotum. Ultrasonography demonstrated hydrocele and a 13 x 12 x 10 mm cystic space along the margin of the right testis. Hydrocelectomy and simple resection of the cyst were performed. Pathologic examination of the excised cyst showed a serous cyst lined with simple flattened epithelium. Ultrasonography is useful for the diagnosis of tunica albuginea cyst.     

Laparoscopic management of persistent mullerian duct syndrome

Persistent mullerian duct syndrome (PMDS), characterized by the presence of mullerian structures in a virilized male, frequently presents as undescended testis, either intraabdominal or within a hernial sac. We describe a 10-month-old infant with PMDS successfully managed by the laparoscopic approach. At the age of 1.5 months, the patient presented with a left inguinal hernia and bilateral nonpalpable gonads in another center and underwent left inguinal exploration. The uterus and a gonadlike structure along with the hernia sac were found in the inguinal canal. Left inguinal herniotomy was performed after reduction of the uterus and gonadlike structure. No gonadal biopsy was obtained. The patient was further investigated in the same center. His karyotype was 46,XY. Magnetic resonance imaging of the abdomen and pelvis revealed a uterinelike structure posterior to the urinary bladder, but neither testis nor ovaries were visualized. At 10 months of age, he was referred to our department for further management. A laparoscopic single-stage orchiopexy was performed. Both testes were identified and brought to the scrotum by splitting the uterus in the midline and then bringing the testes with the vas and attached uterine tissue into the scrotum. The aim of placement of well-vascularized testes in the scrotum was achieved as confirmed on follow-up color Doppler ultrasound study 6 months postoperatively, which showed normal vascularity. Laparoscopic surgical techniques for this condition are also discussed.     

The embryology of the inguinofemoral area: an overview

Summary This paper is an essay to understand the formation of the inguinal and femoral areas by means of an overview of the embryogenesis of the anterior abdominal wall below the umbilicus, as well as by examining the genesis and the descent of the gonads. Developmental considerations of the femoral canal lead to a discussion of the potential explanations for the developmental formation of a femoral hernia sac. The main argument against the congenital origin of femoral hernia is its rarity in infants and children. Despite the lack of irrevocable proof of a developmental defect, femoral hernias do occur in children and they can become strangulated. Some attractive embryological theories which attempt to explain this fact are discussed. “At this time of life the testis is connected in a very particular manner with the parietes of the abdomen, at that place where in adult bodies the spermatic vessels pass out, and likewise to the scrotum. This connection is by means of a substance which runs down from the lower end of the testis to the scrotum, and which at present I shall call the ligament, or gubernaculum testis, because it connects the testis with the scrotum, and directs its course in its descent.” This paper is dedicated to the memory of Omar Askar, who was the real student of the anterior abdominal wall.     

Torsion of a benign cyst arising from the tunica vaginalis testis

We describe a rare case of torsion of a benign cyst originating from the parietal layer of tunica vaginalis. This case presented with acute scrotum. Surgical exploration revealed a cyst arising from the parietal layer of tunica vaginalis of which the pedicle was twisted. When a cystic mass is detected in the scrotum of boys with acute scrotum, torsion of a cyst in the cavum tunica vaginalis testis should be considered.     

A rare simultaneous presentation of testicular mixed germ cell tumor with a contralateral testis torsion

We report a rare case of a 27-year-old man presenting with an acute scrotum with simultaneous occurrence of testicular tumor and contralateral torsion. Preoperative imaging demonstrated the testicular missed torsion, yet findings were equivocal with regard to the testicular tumor. On scrotal exploration the left testis was found to be ischemic due to threefold rotation. The right testis was not identifiable, being composed of numerous necrotic lesions. Frozen section suggested malignancy, hence high right orchiectomy was performed. Histologic examination of the right testis showed mixed germ cell tumor, containing all the subtypes. To our knowledge no similar case has been reported.     

残端疝囊剥离联合腹股沟管引流对巨大腹股沟斜疝术后阴囊并发症的影响

目的探讨残端疝囊剥离联合腹股沟管引流对巨大腹股沟斜疝术后相关阴囊并发症的影响及残端疝囊剥离的手术技巧。方法回顾性分析2010年1月至2013年10月,成都军区总医院收治的巨大腹股沟斜疝患者20例临床资料,疝囊直径≥10cm,进入同侧阴囊。术中均完整剥离残端疝囊并在腹股沟管内放置血浆引流管引流。结果手术均取得成功,剥离残端疝囊时间为3～7min,平均4．6min。剥离残端疝囊出血量：出血量≤2ml12例,出血量～5ml 8例,术后住院时间1～3d,平均1．6d。术后阴囊无明显肿胀,无积液积血。患者无阴囊下坠等不适。结论精细解剖和分离疝外组织,完整剥离疝囊,彻底止血并联合腹股沟管内引流,可减少腹股沟疝术后阴囊并发症的发生。     

Carcinoma of the sigmoid presenting as a right inguinal hernia

We present the case of a 44-year-old man who presented with nausea, vomiting and acute pain in the right groin. On physical examination an irreducible mass was palpated in the right inguinal region. Ultrasound suggested an inguinal hernia sac with bowel contents. Subsequent right inguinal exploration revealed only unspecified necrotizing tissue, but no hernia sac or bowel contents were identified. Two days later laparotomy was required since the inguinal wound produced faecal discharge. The sigmoid appeared to be necrotic and perforated, and was subsequently resected. Histology revealed a perforated adenocarcinoma without lymph node involvement. Incarcerated inguinal hernias containing an adenocarcinoma of the colon are rare, but should be considered in patients presenting with an irreducible palpable mass in the inguinal region. Moreover, a carcinoma of the sigmoid may invade the right inguinal region. An intestinal perforation to skin-level in this population is even rarer and is associated with high morbidity and mortality rates.
