- Traumatic rupture.
- Site of excessive blood cell destruction.
- Idiopathic Thrombocytopenia Purpura (ITP).

- Some neoplastic disease conditions.
What are the methods of splenectomy?
There are two methods for surgical removal of spleen.
- Classical open method and
- Modern laparoscopic method.
Laparoscopic splenectomy is a safe procedure, and can provide less postoperative morbidity in experienced hands, as open splenectomy. Most cases require splenectomy can be treated laparoscopically. Laparoscopic splenectomy is a useful method for reducing hospital stay, complications and return to normal activity. With better training in minimal access surgery now available, the time has arrived for it to take its place in the surgeon's repertoire.
Is all types of splenectomy possible laparoscopically?
Small to moderate sized spleen is very easy to remove laparoscopically. The large sized spleen is difficult to remove by laparoscopic method and better should be approached by open method.
Which organ will work for spleen if spleen is removed?

The spleen acts to provide an early recognition of certain types of bacterial infections, specifically some types of pneumonia. The immunity against certain micro organism is become very less after splenectomy, sometime necessitate long term prophylactic antibiotic and periodic vaccination.
What are the contraindications of laparoscopic splenectomy?
Relative contra-indications of Laparoscopic splenectomy.
1 Hugely enlarged appendix
2 Poor risk for general anaesthesi
3 some cases of previous extensive abdominal surgery
The general anaesthesia and the pneumoperitoneum required as part of the laparoscopic procedure do increase the risk in certain groups of patients. Most surgeons would not recommend laparoscopic splenectomy in those with pre-existing disease conditions. Patients with Cardiac diseases and COPD should not be considered a good candidate for laparoscopy. The laparoscopic splenectomy may also be more difficult in patients who have had previous abdominal surgery. The elderly may also be at increased risk for complications with general anaesthesia combined with pneumoperitoneum.
Can the spleen ever grow back?
It is impossible that after removal spleen grows. But, if small pieces are left behind at the time of surgery after a ruptured spleen, they may survive and some time start functioning. Some people have accessory spleens difficult to find during an operation to remove.
Is this all very expensive? How can one justify the cost of the equipment and surgery ?
The cost of laparoscopic equipment and instrument increases the cost of surgery. Unfortunately these are still imported and will remain expensive till thy are locally produced. However, the increased cost should be compared with the gain associated by a quicker and more productive return to work by the majority of the patients. The hidden lowering of cost is due to less leave, early return to normal activity and work, and also from the greatly reduced disruption of the family routine.
