Torsion causing interruption of the ampullary portion of the fallopian tube

Unilateral Partial Absence of the Fallopian Tube in a Female Patient With Infertility: A Case Report and Literature Review

Unilateral partial absence of the fallopian tube is rare, and its clinical importance in fertility is unclear. A 35-year-old nulligravid female patient with infertility was suspected to have a left hydrosalpinx on hysterosalpingography and sonography. Therefore, the patient underwent diagnostic laparoscopy. The left fallopian tube lacked the ampullary portion, and its proximal end had a hydrosalpinx. A left salpingectomy was performed, and the pathological finding was a unilateral partial absence of the ampullary portion of the fallopian tube with hydrosalpinx. Postoperatively, she conceived via in vitro fertilization-embryo transfer-and delivered a healthy baby. Hydrosalpinx is a well-known cause of infertility and can develop due to the partial absence of a fallopian tube. Furthermore, salpingectomy may be effective in improving fertility in female patients with a unilateral partial absence of the fallopian tube.

Isolated fallopian tube torsion with paraovarian cysts: a case report and literature review

BACKGROUND

Isolated fallopian tube torsion (IFTT) is a rare cause of gynecological acute abdomen, is easily misdiagnosed and often has a delay in diagnosis. IFTT with paraovarian cysts is most frequently reported in studies. Here, we reported a patient diagnosed with IFTT associated with a paraovarian cyst, and we conducted a literature review for IFTT, aiming to identify valuable information that will be helpful for diagnosis and treatment for fallopian tube torsions.

CASE PRESENTATION

A 13-year-old girl presented with a 10-day history of right lower abdominal pain that worsened 2 days before presentation. On presentation, ultrasound showed a 5.8 * 5.5 cm hypoechoic cyst adjacent to the right ovary, and between the cyst and ovary, a tortuous thickened tube was visualized. Laparoscopy revealed a triple torsion of the right fallopian tube with a 6-cm paraovarian cyst, and tubal conservation surgery was performed. The postoperative course was uneventful. Histopathological diagnosis revealed serous papillary cystadenoma.

CONCLUSION

Paraovarian cystic dilatation often occurs in adolescence and can induce fallopian torsion when the size of the cyst reaches 5-cm. In our review, the median age of patients diagnosed with IFTT with paraovarian cysts was 15 years old, and the main clinical manifestation was emergency abdominal pain. The associated symptoms were variable, and vomiting was the most commonly associated symptom. Salpingectomy was the most common procedure performed; however, timely surgical intervention can effectively avoid salpingectomy.

Laparoscopic treatment of isolated salpingeal torsion in children: case series and a 20-year review of the literature

BACKGROUND

Isolated torsion of the Fallopian tube, without ovarian torsion, is a rare cause of lower abdominal pain. We report our experience with 4 recent cases, along with data from a 20-year review of the pediatric literature.

SUBJECTS AND METHODS

The records of 4 cases encountered during a 3-year period were reviewed. A literature review was completed by searching Medline, Medline in Process, Embase, Current Contents, and BIOSIS from 1990 to 2010.

RESULTS

All 4 patients were diagnosed on laparoscopy. Laparoscopic salpingectomy was performed in 3 cases and laparoscopic detorsion in 1. All three resected specimens revealed hemorrhage and gangrene of the salpinx, with an associated cyst in one. The pediatric literature review, including our report, revealed 33 case reports and case series with 45 patients. Fifty-six percent of cases represented primary torsion, and 44% were secondary to underlying tubal pathology. Thirty percent of girls were premenarchal. The mean age at presentation and symptom duration were 13.2±2.1 years and 5.8±12.5 days, respectively. Fever and leukocytosis were present in 27% and 63%, respectively. Ultrasound, computed tomography scan, and magnetic resonance imaging showed a sensitivity of 22% (8/36), 14% (1/7), and 40% (2/5), respectively. A correct preoperative diagnosis was considered in only 13%. Eighty-eight percent of cases were treated by salpingectomy, and 12% were treated by tubal detorsion. Long-term outcomes of detorsion were not reported.

CONCLUSIONS

Isolated salpingeal torsion in girls is rarely diagnosed preoperatively, regardless of imaging technique. Laparoscopy is the intervention of choice for definitive diagnosis and management. Salpingectomy is the most frequent treatment. Detorsion without resection may be considered for selected cases, but the long-term outcomes of this approach are unknown.
