== Management == | |||
=== Hepatic adenoma === | |||
Management of hepatic adenoma depends upon: | |||
* Symptoms | |||
* Size | |||
* Number | |||
* Location | |||
* Certainty of the diagnosis | |||
==== '''Asymptomatic woman on OCPs with a small adenoma''' ==== | |||
The European Association for Study of the Liver recommends | |||
* Discontinuation of contraceptive medication | |||
* Close observation of the lesion with repeated imaging and alpha fetoprotein. | |||
** Contrast-enhanced magnetic resonance imaging at a six month interval to determine if there is regression of a large adenoma to less than 5 cm. | |||
* Patients with hepatic adenomas that do not resolve or that enlarge after six months of observation should undergo treatment. | |||
==== Symptomatic patients and those with large adenomas ==== | |||
* Surgical resection is recommended for all symptomatic patients with hepatic adenoma and those with large lesions (>5 cm). | |||
* Surgical options include : | |||
** Enucleation | |||
** Resection | |||
** Liver transplantation | |||
* Nonsurgical interventions include | |||
** Transarterial embolization | |||
** Radiofrequency ablation | |||
=== Hepatic Hemangioma === | |||
* '''Asymptomatic patients''' | |||
** Patients with lesions <1.5 cm, are reassured and observed. | |||
** Follow-up imaging in patients with hemangiomas ≤5 cm in size is usually not recommended. | |||
** Patients with rapid growth of a hemangioma or with lesions >5 cm it is recommended to repeat imaging in 6 to 12 months. | |||
** It is recommended not perform additional imaging if there is no change in the size of the lesion. | |||
* '''Symptomatic patients''' | |||
** Patients who have pain or symptoms suggestive of extrinsic compression of adjacent structures should be considered for surgical options. | |||
** Surgical options include | |||
*** Liver resection | |||
*** Enucleation | |||
*** Hepatic artery ligation | |||
*** Liver transplantation | |||
** Non-surgical techniques include | |||
*** Hepatic artery embolization | |||
*** Radiotherapy | |||
*** Interferon alfa-2a | |||
=== Focal nodular hyperplasia === | |||
* Due to their benign nature of focal nodular hyperplasia, there is | |||
* Follow-up studies at three and six months will often be sufficient to confirm the stability of the lesion and its benign nature, after which no long-term follow-up is required routinely. | |||
* Surgery should be reserved for symptomatic FNH lesion. | |||

Overview
Lower gastrointestinal bleeding, commonly abbreviated LGIB, refers to any form of bleeding in the lower gastrointestinal tract.
Causes
- Coagulopathy - specifically a bleeding diathesis
- Colitis
- Hemorrhoids
- Angiodysplasia
- Neoplasm - cancer
- Diverticular disease - diverticulosis, diverticulitis
Diagnosis
The following suggest an LGIB:
- Melena and a negative oesophagogastroduodenoscopy
- Hematochezia
- Fecal occult blood
The following may suggest an LGIB:

Management
Hepatic adenoma
Management of hepatic adenoma depends upon:
- Symptoms
- Size
- Number
- Location
- Certainty of the diagnosis
Asymptomatic woman on OCPs with a small adenoma
The European Association for Study of the Liver recommends
- Discontinuation of contraceptive medication
- Close observation of the lesion with repeated imaging and alpha fetoprotein.
- Contrast-enhanced magnetic resonance imaging at a six month interval to determine if there is regression of a large adenoma to less than 5 cm.
- Patients with hepatic adenomas that do not resolve or that enlarge after six months of observation should undergo treatment.
Symptomatic patients and those with large adenomas
- Surgical resection is recommended for all symptomatic patients with hepatic adenoma and those with large lesions (>5 cm).
- Surgical options include :
- Enucleation
- Resection
- Liver transplantation
- Nonsurgical interventions include
- Transarterial embolization
- Radiofrequency ablation
Hepatic Hemangioma
- Asymptomatic patients
- Patients with lesions <1.5 cm, are reassured and observed.
- Follow-up imaging in patients with hemangiomas ≤5 cm in size is usually not recommended.
- Patients with rapid growth of a hemangioma or with lesions >5 cm it is recommended to repeat imaging in 6 to 12 months.
- It is recommended not perform additional imaging if there is no change in the size of the lesion.
- Symptomatic patients
- Patients who have pain or symptoms suggestive of extrinsic compression of adjacent structures should be considered for surgical options.
- Surgical options include
- Liver resection
- Enucleation
- Hepatic artery ligation
- Liver transplantation
- Non-surgical techniques include
- Hepatic artery embolization
- Radiotherapy
- Interferon alfa-2a
Focal nodular hyperplasia
- Due to their benign nature of focal nodular hyperplasia, there is
- Follow-up studies at three and six months will often be sufficient to confirm the stability of the lesion and its benign nature, after which no long-term follow-up is required routinely.
- Surgery should be reserved for symptomatic FNH lesion.
