They are mainly acquired and usually associated with inguinal hernia. The external and the internal variety of SVH is commonly presented as direct inguinal hernia and intestinal obstruction or undiagnosed abdominal pain respectively. Case Report: A 40 year old male was posted for TransAbdominal PrePeritoneal (TAPP) hernia repair for a direct inguinal hernia. Intraoperatively we diagnosed him with a supravesical hernia with an unusual internal opening over the medial umbilical ligament. Discussion: SVH is a rare variety of pelvic hernia which protrudes through Supra Vesical or Paravesical Fossa (SVF). SVF is an area above the urinary bladder between the median umbilical ligament and medial umbilical ligament. CT/MRI sometimes helps in obtaining the diagnosis but mainly it was made intraoperatively. Simple closure of the internal opening is sufficed for treating this form of hernia. Conclusion: Preoperative diagnosis of SVH is difficult to establish. CT/MRI can sometimes diagnose internal SVH but in majority, the diagnosis was made intraoperatively. Whenever we are dealing with direct inguinal hernia we should be aware of the possibility of this rare form of hernia especially if there is any difference in anatomical relation during surgery. _____________________________________________________________________________________________________ *Corresponding author: E-mail: [email protected]; Shyam; AJCRS, 2(2): 1-4, 2019; Article no.AJCRS.46765 Keywords: Supravesical fossa; Supravesical hernia; medial inguinal fossa; intestinal obstruction. 1. INTRODUCTION We refashioned 15 × 15 polypropylene mesh into 12 × 15 cm size, and we used one or two Supravesical fossa (SFV) is the area between absorbable tackers each to fix the mesh with the median and medial umbilical ligaments [1] Cooper’s ligament, medial border of rectus and hernia which develop from this fossa are muscle, medial and lateral space to epigastric termed as Supravesical hernia (SVH) or vessels. Postoperative hospital stay was paravesical hernia [2]. It is a rare condition, and uneventful. The Patient was on regular follow up Sir Astley Cooper reported the first case of for his associated hemorrhoid problem and till his Supravesical hernia in 1804 [1].

The Patient gave a the cause of SVH [2]. Primary SVH is very rare history of occasional constipation and chronic compared to secondary SVH [5], which are smoking for 28 years. There was no history of mostly acquired and usually associated with an chronic cough, difficulty in passing urine, inguinal hernia or followed by surgery [3]. bleeding per rectum or any surgical intervention or trauma in the past. Physical examination There are two variants of SVH: the external revealed a 4 cm soft oval swelling above the variety which occurs in the superior portion of the inguinal ligament. The swelling was reducible SFV is due to the laxity of the vesical and positive for cough impulse test.
