Locally advanced carcinoma of the cecum presenting as a right inguinal hernia: a case report and review of the literature

Perforated sigmoid colon adenocarcinoma within an irreducible inguinal hernia: A case report

Inguinal hernia is a potentially occult common surgical condition. Its association with asymptomatic adenocarcinoma is uncommon. However, malignancy-associated perforation of the large bowel within an irreducible hernia is rare. We report a case of 78-year-old male presenting with a long-standing inguinal hernia with a 2-day history of irreducibility. Examination revealed a large left-sided irreducible inguinal hernia. Patient underwent urgent inguinal herniotomy, during which multiple perforations were noted in the sigmoid colon. Patient underwent Hartmann’s procedure following bowel resection. Histology revealed a mucinous adenocarcinoma with extensive metastasis involving the resection margins. Elderly patients with long-standing inguinal hernia presenting with acute symptoms should be evaluated further for this rare but sinister diagnosis.

Metastatic colon adenocarcinoma presenting as a giant inguinal hernia: A case report

INTRODUCTION AND IMPORTANCE

Giant inguinoscrotal hernias (GIH) are a rare form of inguinal hernia. There have been few reported cases of GIH containing colon adenocarcinoma.

CASE PRESENTATION

This case describes a 72-year-old male with a right GIH containing the right colon, terminal ileum, and associated mesentery with a large heterogenous, irregular mass with necrosis involving the cecum and ascending colon measuring 14 × 8 × 9 cm. The patient initially presented with pain and evidence of partial large bowel obstruction. Due to suspected extensive local invasion of tumor, the patient was scheduled for evaluation for possible neoadjuvant chemotherapy. Unfortunately, the patient re-presented with a large bowel obstruction and was subsequently taken for an exploratory laparotomy with trans-scrotal incision for en bloc resection of cecal adenocarcinoma and involved hernia contents.

CLINICAL DISCUSSION

Due to the rarity of this pathology, there is not a standard approach to management or optimal surgical technique described. In this case, a trans-scrotal incision paired with an exploratory laparotomy allowed for superior access to the adhered cancer containing bowel as well as skin excision, following standard oncologic principle of high ileocolic mesenteric excision.

CONCLUSION

The complexity of management of GIH containing colon cancer has been documented, however a standard oncologic approach has not been described. This case report presents exploratory laparotomy with trans-scrotal incision as an approach.

A Rare Case of Sigmoid Colon Carcinoma in Incarcerated Inguinal Hernia

Incarcerated inguinal hernia is a common diagnosis in patients presenting a painful and nonreducible groin mass. Although the diagnosis is usually made by physical examination, the content of the hernia sac and the extent of the surgical operation may vary and can require multimodal imaging integration (e.g., ultrasonography, computed tomography); the usual finding is a segment of small bowel and, less commonly, large bowel. We present an extremely rare case of a sigmoid cancer incarcerated in a left inguinal hernia and infiltrating the spermatic cord. The patient underwent whole-body computed tomography (CT) with contrast agent injection for staging, followed by a left hemicolectomy paralleled by a unilateral orchiectomy.

A rare case of ascending colon adenocarcinoma incarcerated in an inguinoscrotal hernia: case report and literature review

Background

Inguinal hernias and colorectal cancers are common conditions, but the presentation of a loop of bowel containing cancer within a hernia is rare. Principles of surgery include oncological resection of the involved colonic segment as well as lymphatic drainage. Based on case reports of the last several decades, there have been no reports of a case where the reduction of an inguinoscrotal hernia and oncological colectomy were performed completely laparoscopically. We present the first instance of a completely laparoscopically assisted resection and hernia repair on a patient with T4 ascending colon cancer. A literature search on recent case reports over the last 30 years has also been presented with a focus on trends in treatment.

Case presentation

An 83-year-old man presented for further investigation of his iron deficiency anaemia and was diagnosed with adenocarcinoma of the ascending colon. This was demonstrated radiologically to be found within a large right inguinoscrotal hernia. He underwent a laparoscopically assisted right hemicolectomy and laparoscopic closure of the internal ring and recovered well.

Conclusions

Colorectal cancers within inguinal hernias are rare and can often present with complications such as perforation. As such, treatment has mostly involved an open operation. The last few years have shown feasibility of a laparoscopic approach and can be attempted safely when indicated.

Inguinoscrotal herniation of a caecal adenocarcinoma

An 84-year-old man with multiple comorbidities presented from a residential care home with a 1-month history of asthenia and moderate abdominal pain. On examination, he was found to have an irreducible right-sided inguinoscrotal hernia. Subsequent blood tests revealed a significant anaemia (haemoglobin 48 g/L), for which he was transfused. A CT scan of the abdomen and pelvis revealed a large caecal tumour, herniating through the right inguinal canal into the scrotum. The patient underwent an elective open right hemicolectomy with inguinal hernia defect repair, from which he recovered well. He was discharged from the ward 12 days postoperatively and is awaiting outpatient follow-up.

Parasitised large intestinal diverticulum of the spermatic cord

We present a 70-year-old male patient with an unusual incidental finding at an elective repair of an indirect left inguinal hernia (LIH). A black nodule resembling a melanoma metastasis in a lymph node was discovered attached to the spermatic cord. There was no contiguity with the large bowel on the same side. Histological examination showed an isolated, detached colonic diverticulum containing a faecolith. We postulate derivation from an incarcerated colonic diverticulum that became 'parasitised' onto the spermatic cord.
