## Abstract

We describe here a two-year-old male who required urgent laparotomy to relieve a strangulated small bowel caused by internal herniation around an intra-abdominal testis. This clinical presentation has not been reported previously.

## Body

## 1. Case Report

A 2-year-old boy presented with a 3-day history of diffuse abdominal cramping, nausea, vomiting, constipation, and progressive abdominal distension. There was no perinatal history of exposure to toxins, and prenatal ultrasound revealed no abnormalities.Physical examination showed that the child was dehydrated, with a diffusely distended and tender abdomen, but no erythema or crepitus. His right scrotum was empty, with no testis present in his groin, while the contralateral testis was normal. Plain abdominal radiology revealed typical features of low-mechanical small bowel obstruction with numerous gas-fluid levels (Figure1). Abdominopelvic sonography showed a fair amount of ascites in the pelvis with localized thickening of bowel loop walls in the right lower abdominal quadrant. Moreover, radiology showed no testis in his pelvis or scrotum.Figure 1
A plain abdominal X-ray shows small bowel intestinal obstruction.We performed urgent laparotomy through a right transverse supraumbilical incision that revealed an ischemic loop of terminal small bowel herniating below an intra-abdominal testis residing freely in the peritoneal cavity, with its gubernaculum adherent to the terminal ileum (Figure2). We performed simple reduction of the ischemic loop, which regained its viability shortly afterward. The gubernaculum was freed from its attachment to the terminal ileum. The testis was viable and of normal size and could be brought down and fixed to the scrotum utilizing additional small inguinal creases and scrotal incisions (Figure 3).Figure 2

Followup in our outpatient clinic 3 months later revealed a normal-sized right testis properly residing in the scrotum.


## 2. Discussion

Failure of a testis to reside properly within the scrotum after birth usually leads to increased rates of infertility and malignancy. Other dangers include increased risks of torsion and trauma, in addition to the psychological impact of an absent testis [1, 2].Intestinal obstruction due to internal herniation is rare, reported in only 1% of patients with these obstructions [3].  Intestinal obstructions usually occur in the paraduodenal area (50%), but they may also occur in the transmesenteric, pericecal, intersigmoid, and supravesical areas [4]. Acute small bowel obstruction in the absence of previous surgery or external hernia is suggestive of internal hernia, despite its rarity. Compressed internal hernias may also cause strangulation and immediate gangrene [5].We report what is, to our knowledge, the first case of a young child with an acutely strangulated small bowel that internally herniated around an intra-abdominal testis and was obstructed by it.  It remains unclear whether the testis is an intra- or extraperitoneal organ. Although adult anatomy texts favor an extraperitoneal position, intraperitoneal testes have been observed in patients with gastroschisis, spigelian hernia, and testicular torsion [6].Moreover, it has been suggested that, instead of following the processus vaginalis, the testis actually pulls out the peritoneal pouch into the scrotum [7, 8]. In contrast, the processus vaginalis may be an invagination of the peritoneal cavity into the extraperitoneal gubernacular mesenchyme, suggesting that the testes are extraperitoneal [9]. The findings in our patient, however, support the theory that the testes are intraperitoneal organs.
