Inferior mesenteric plexus block(IMPB) is a nerve block for lower abdominal pain originating from GI tract of distal transverse colon to sigmoid colon and other polvic organ where the inferior mesenteric plexus contains visceral afferent fibers of that organ. We performed IMPB on two patients with lower abdominal pain. Case I: 61 year old female diagnosed with cancer of stomach and uterine cervix and carcinomatosis, experienced complete relief from pain for a period of 7 months after IMPB. Case II: male, 28 years old, who had contracted cancer of the descending colon with obstructive jaundice and pancreatitis had complained of pain in the whole of the abdominal area. IMPB was performed for lower abdominal pain. Seven days after, a celiac plexus block was also performed for upper abdominal pain. The patient complained of recurring pain in the left & upper lower abdomen 30 days after the IMPB. The intensity of the pain was visual analogue scale 4 and it was managed by continuous epidural block. Conclusion: It is our recommendation that IMPB is a reliable method for treatment of lower abdominal pain originating from malignant condition of GI tract from distal transverse colon to sigmoid colon and urinary bladder.

Inferior mesenteric plexus block(IMPB) sa useful nerve block for the relief of intractable lower abdominal and pelvic pain caused by a lower abdominal visceral or a pelvic malignancy. IMPB has been performed in the prone position. But there are many patients who can't lie in the prone position, because ascites is frequently noticed in cancer patients and they also frequently received abdominal operations. We performed IMPB in the lateral position on two patients with lower abdominal pain, Case 1: A 77 year old female who had a right ovarian cancer with metastatic cancer of descending colon and rectum, experienced complete pain relief. Case 2: A 72 year old female who had a far advance pancreatic cancer with intestinal obstruction due to carcinomatosis received right and left celiac plexus block and right and left IMPB. The patient was satisfied with the result of these pain blocks. Conclusion; IMAPB performed in the lateral position on two patients with lower abdominal pain and their results were excellent for pain relief.
