Sigmoid carcinoma in an inguinal hernia: a blessing in disguise?

Non-operative management of gallstone sigmoid ileus in a patient with a prostatic cancer

Gallstone ileus is an uncommon complication of calculus cholecystitis through the formation of a biliary enteric fistula. The risk of mechanical obstruction caused by gallstones is increased with its size, in addition to chronic constipation, neoplasm and diverticulitis, to name a few. Here, we present a case of an 89-year-old male patient who presented with signs of bowel obstruction, which was found to be a gallstone impacted in the sigmoid colon. Considering the patient's stable condition and his comorbidities, a conservative approach was opted including IV fluids, fleet enema and bowel rest. Colonoscopy was performed and confirmed the passage of the stone. With no consensus regarding the management, the literature emphasizes a tailored approach to each case considering all possible operative and non-operative approaches. Some reports show promising results with non operative management. Gallstone ileus remains a challenging case, and further studies for the best treatment modalities are needed.

Perforated sigmoid colon cancer presenting as an incarcerated inguinal hernia: A case report

BACKGROUND

Inguinal hernias are common among the population and usually contain part of the omentum or small bowel, however, other unusual contents have been reported. We report a case of a patient who presented for an incarcerated left inguinal hernia and was found to have an underlying perforated sigmoid cancer.

SUMMARY

An 87 years old man presented with typical signs of an incarcerated left inguinal area. During surgery, we dissected free a herniated hard inflammatory mass until it was found to be covering an underlying perforated sigmoid tumor. Inguinal hernia is a common condition affecting many individuals, and colorectal cancer is one of the rare contents reported inside these hernias. Due to the rarity of such a presentation, the surprise encounter during groin surgery may lead to suboptimal treatment. Perforated colorectal cancer, like in our case, may signify a more aggressive disease, and hence a correct diagnosis is crucial to improve outcomes. When underlying colon cancer is suspected during hernia surgeries, proper exploration and oncologic resection might be the optimal choice.

CONCLUSION

Surgeons should keep the possibility of underlying colorectal cancer in mind when operating on inguinal hernias and opt for oncologic resection of the identified tumor along with proper lymph node dissection.

An irreducible left scrotal hernia containing a sigmoid colon tumor (adenocarcinoma) - Case report

INTRODUCTION

In relation to all inguinal hernias, large irreducible scrotal hernias are quite rare, while such hernias containing colon tumors in the sac have so far been described in fewer than 30 cases.

PRESENTATION OF CASE

A 61-year-old patient was admitted for a planned surgery because of a large irreducible left-sided scrotal hernia. Intraoperatively, a large tumor of the sigmoid colon was found in the hernial sac. In a histopathological examination it was diagnosed as adenocarcinoma. A palliative operation was performed and he was referred to further systemic and palliative treatment (because of numerous coexisting liver metastases).

DISCUSSION

Until now, only about 30 cases of colon tumor in inguinal hernia sac have been reported.

CONCLUSION

It should be remembered that even the most obvious preoperative diagnosis may be verified intraoperatively.
