Project description:BackgroundWandering spleen (WS) is a rare clinical entity resulting from the absence or maldevelopment of the ligaments normally involved in the attachment of the spleen in its normal position. WS can be a cause of acute abdomen leading to different complications ranging from torsion of the vascular pedicle to spleen infarction. Often, in absence of symptoms, it is an occasional finding during radiological exams and surgery represents the gold standard in the management of this unusual condition.Case presentationWe present a case of wandering spleen in a young nulliparous female with an history of recurrent abdominal pain. A preoperative CT-scan of the abdomen showed the presence of a multi-infarcted spleen twisted several times around its vascular pedicle, involving the tail of pancreas. The patient was electively treated with laparoscopic splenectomy.ConclusionsA laparoscopic approach is feasible in the treatment of this pathology. A correct and timely diagnosis of this condition is crucial to allow an organ preserving surgery. There are only few reported cases in literature describing an involvement of the tail of the pancreas in the torsion of the vascular pedicle. Complete excision of the ectasic veins tributaries of the splenic vein avoids the risk of postoperative vein thrombosis and bleeding.

Project description:Wandering spleen is a rare disease that is easily misdiagnosed. When combined with splenic pedicle torsion and even splenic infarction, wandering spleen is a rare and critical cause of surgical acute abdomen. We report an 18-year-old male patient with abdominal organ inversion diagnosed as acute appendicitis before operation. Laparoscopic exploration confirmed wandering spleen with splenic pedicle torsion led to splenic infarction and was complicated by appendicitis. He was treated with laparoscopic appendectomy and abdominal splenectomy. The patient recovered well after the operation and was discharged from the hospital in 7 days. During the 4-year follow-up, there was no report of complicated infections such as pneumonia or sepsis.

Project description:Accessory spleens are found in 10-15% of the population, and are even more prevalent in patients with hematological disorders (Rudowski, 1985). It infrequently may become symptomatic due to torsion, spontaneous rupture or hemorrhage which may lead to death. Torsion of an accessory spleen is extremely rare, and requires prompt medical attention [2] (Coote et al., 1999).We report the case of a 27-year-old Mediterranean lady with thalassemia trait, who presented to the emergency department with an acute surgical abdomen due to torsion of a giant accessory spleen, measuring 13cm. She was diagnosed with the aid of ultrasound and computed tomography (CT) scan and was treated surgically through resection of the spleen.Torsion of an accessory spleen is not common, and is the surgical indication in about 0.2-0.3% of splenectomies (Mortele et al., 2004). It has variable clinical presentations, and is a difficult preoperative diagnosis due to lack of specificity of symptoms. Accessory spleens are usually smaller than 3cm, with few cases being reported as larger than 10cm larger accessory spleens have a higher rate of torsion. Knowledge of this pathology, and familiarity with its radiological findings are fundamental to accurately diagnosing and manageming this challenging condition.

Project description:A wandering spleen is a rare condition in which the spleen is not located in the left upper quadrant, but instead is found in the lower abdomen or in the pelvic region because of the laxity of the peritoneal attachments. The unusually long pedicle is susceptible to twisting, which can lead to ischemia, and eventually to necrosis. We herein report a case of an enlarged wandering spleen with torsion, successfully treated by single-incision laparoscopic splenectomy and autotransplantation. The transplanted splenic tissues could be identified on a spleen scintigram obtained 3 months after the surgery. Howell-Jolly bodies were not observed in blood specimens. This procedure is able to prevent an overwhelming postsplenectomy infection, and leads to satisfactory cosmetic results.

Project description:A 15-year-old boy with extralobar sequestration torsion is presented, who presented as an acute abdomen. Chest X-ray and computed tomography on admission revealed an apparent posterior mediastinal mass on the right side at the lower thoracic vertebral level. MR imaging, however, clearly showed scanty fluid around the mass and the subpleural fat layer between the vertebral body and the mass, suggesting its extrapulmonary and intrapleural cavity location. Its hemorrhagic nature was also suggested by the reduced signal on the in-phase as compared to out-of-phase chemical shift images, which helped make correct preoperative diagnosis.

Project description:Introduction and importanceThe spleen is normally found in the left hypochondrium and it is fixed in its place by numerous suspensory ligaments. When the ligaments are elongated or abnormally developed, it causes a rare medical condition called Wandering spleen. A persistent ascending and descending mesocolon is also a congenital anomaly, resulting from the failure of fusion of the primitive dorsal mesocolon.Case presentationHerein, a 5-year-old male child with sudden and acute onset of abdominal pain, constipation, nausea, tachycardia, and low urine output, imaging and blood tests revealed evidence of intestinal obstruction and normocytic anemia and neutrophilia. A laparotomy revealed persistent ascending and descending mesocolon, with a torsioned vascular pedicle of the spleen, resulting in splenomegaly and infarction. The surgeon successfully derotated the torsioned pedicle and performed a splenectomy. The patient had an uneventful postoperative course and was discharged without complications.Clinical discussionThis case could be asymptomatic and the diagnosis is incidental or it could be presented with ambiguous symptoms. The differential diagnosis of WS varies according to the clinical presentation and the associated complication. For instance, in the case of WS torsion and acute presentation, the differential diagnosis is ovarian torsion, acute appendicitis, and intestinal obstruction. Currently, surgery is the only suggested treatment option even in asymptomatic patients as well.ConclusionThis case of a Wandering Spleen is associated with a persistent ascending and descending mesocolon, suggesting that there may be certain risk factors. Therefore, we suggest making more research about wandering spleen in association with persistent mesocolon.

Project description:ObjectiveThe purpose of our study was to assess computed tomographic (CT) findings of adnexal torsion through a matched case-control analysis.Materials and methodsThis retrospective, single-institution case-control study included 43 women with adnexal torsion and 43 age- and ovarian mass-matched control women. CT images were evaluated independently by two readers for the following: prominent peripheral follicles, uterine deviation, thickened pedicles, a whirl sign, and a navel sign. Comparisons of CT findings were performed using the Chi square test and receiver operating characteristic (ROC) curves were obtained to assess the diagnostic performance. Differences between the areas under the ROC curves (AUCs) were compared by using a Delong test.ResultsThe CT findings significant for adnexal torsion were uterine deviation toward the side of the affected ovary (P = < .01 for reader 1 and P = .02 for reader 2) and thickened pedicles with ancillary findings including a whirl sign, a navel sign, and uterine deviation facing thickened pedicles (P < .01 for both readers). Thickened pedicles with ancillary findings had the highest diagnostic accuracy, as measured with ROC curves (AUC, 0.86 in reader 1 and 0.85 in reader 2). Combining uterine deviation toward the side of the affected ovary with thickened pedicles with ancillary findings did not increase the performance relative to that of thickened pedicles with ancillary findings alone.ConclusionsThickened pedicles with ancillary findings including a whirl sign, a navel sign, and uterine deviation facing thickened pedicles could be helpful for the diagnosis of adnexal torsion.

Project description:For acute adnexal torsion of pregnant women, appropriate treatment based on an accurate diagnosis is especially important for fertility preservation and timely treatment. The 2017 American College of Obstetricians and Gynecologists (ACOG) Committee Opinion No. 723 announced its practice-changing guidelines to ensure that diagnostic magnetic resonance imaging (MRI) conducted during the first trimester and gadolinium exposure at any time during pregnancy are safe for fetal stability. Unfortunately, few studies have been performed to evaluate the usefulness of the diagnostic accuracy of MRI for acute adnexal torsion during pregnancy. We sought to determine the efficacy of diagnostic MRI modality using multiparameter for maternal adnexal torsion during pregnancy. From 1 January 2007 to 31 January 2019, 131 pregnant with MRI tests were reviewed. In this retrospective cohort study, 94 women were excluded due to conditions other than an adnexal mass, and 37 were identified through MRI analyses conducted before surgery for suspected adnexal torsion. The primary outcome was the diagnostic accuracy of sonography and MRI, and the secondary outcome was the usefulness of Apparent diffusion coefficient (ADC) values for predicting the severity of hemorrhagic infarction between the medulla and cortex of the torsed ovarian parenchyma. Our study demonstrates that in the diagnosis of adnexal torsion during pregnancy, the sensitivity, specificity, positive predictive value, and negative predictive value are 62.5%, 83.3%, 90.9%, and 45.5% for sonography and 100%, 77.8%, 90.5%, and 100% for MRI. MRI results in surgical-proven adnexal torsion patients revealed unilocular ovarian cysts (36.8% (7/19)), multilocular ovarian cysts (31.6% (6/19)), and near normal-appearing ovaries (31.6% (6/19)). Pathology in adnexal torsion revealed a corpus luteal ovarian cyst (63.2% (12/19)) and underlying adnexal pathology (46.8% (7/19)). Maternal adnexal torsion during pregnancy was more likely to occur in corpus luteal ovarian cysts than in underlying adnexal masses (odds ratio, 2.14; 95% confidence interval (CI), 0.428-10.738). MRI features for adnexal torsion were as follows: tubal wall thickness, 100% (19/19); ovarian stromal (medullary) edema, 100% (19/19); symmetrical or asymmetrical ovarian cystic wall, 100%(19/19); prominent follicles in the ovarian parenchyma periphery, 57.9% (11/19); periadenxal fat stranding, 84.2% (16/19); uterine deviation to the twisted side, 21.1% (4/19); and peritoneal fluid, 42.1% (8/19). The signal intensity of the ADC values of the ovarian medulla and cortex were compared between the cystectomy and detorsion (CD) and salpingo-oophorectomy (SO) groups. The ADC values of the CD and SO groups were 1.81 ± 0.09 × 10-3 mm2/s and 1.91 ± 0.18 × 10-3 mm2/s, respectively (P = 0.209), in the ovarian medulla and 1.37 ± 0.32 × 10-3 mm2/s and 0.96 ± 0.36 × 10-3 mm2/s, respectively (P = 0.022), in the ovarian cortex. The optimal cut-off value of ADC values for predictable total necrosis in the torsed ovarian cortex was ≤ 1.31 × 10-3 mm2/s (area under the curve (AUC) = 0.81; 95% CI 0.611-1.0; P = 0.028). Our data showed that maternal adnexal torsion during pregnancy occurred in most corpus luteal cystic ovary cases and some normal-appearing ovary during the 1st and 2nd trimesters of gestation. Therefore, this study is the first study to elaborate on the existence or usefulness of the diagnostic MRI for acute maternal adnexal torsion during pregnancy and to provide a predictive diagnosis of the severity of hemorrhagic infarction for deciding surgical radicality.

Project description:Purpose: Aim of the study was to investigate the incidence, progress, management and outcome of adnexal torsion after controlled ovarian hyperstimulation in embryo transfer cycles. Materials and Method: A retrospective analysis was done of 1007 patients of a private IVF centre. The literature on adnexal torsion is reviewed. Results: In the literature, the incidence of adnexal torsion after assisted reproductive technologies (ART) is given as around 0.2?%. A significant increase of up to 33?% has been reported for cases with additional ovarian hyperstimulation syndrome (OHSS) and in pregnant women. In our retrospective analysis of 1007 women (incidence 0.46?%) with 1411 fresh embryo transfer cycles, we found an incidence of 0.35?% per embryo transfer. All adnexal torsions were treated by laparoscopic derotation to preserve fertility. All 5 cases with torsion were pregnant, 2 patients had mild OHSS. We recorded 3 term deliveries, 1 induced abortion for sirenomelia, and 1 missed abortion. Conclusion: Adnexal torsion must be kept in mind after hyperstimulation and embryo transfer, especially when pregnancy or OHSS is also present. With early diagnosis, it should be possible to preserve fertility using laparoscopic derotation.

Project description:IntroductionWandering spleen (WS) is a clinical entity in which the spleen is not located in its normal anatomical site. Few cases have been reported, mainly in women of childbearing age. This condition can be congenital or acquired due to excessive elasticity of the spleen's suspensory ligaments. WS may cause acute complications requiring emergency surgery, especially related to the rotation of its vascular pedicle, leading to chronic or acute ischemia. The aim of the present case is to show a rare complication of WS, small bowel obstruction (SBO), and its management.Presentation of caseWe report the case of a 40-year-old female presenting with abdominal pain, nausea, and vomiting. CT scan showed SBO caused by WS located in the pelvis with an enlarged spleen vascular pedicle (SVP). Laparoscopic exploration, splenectomy, small bowel resection and anastomosis were performed.DiscussionWS may cause chronic or acute complications, mainly linked with enlargement and torsion of SVP, including acute ischemia and spleen necrosis, or compression of the near organs such as small intestine, stomach, pancreas. The diagnosis is based on physical examination, CT scan and blood exams. Generally, the WS's treatment is laparoscopic splenectomy or splenopexy. In case of vital spleen, splenopexy can be performed, in case of not vital spleen, splenectomy should be preferred.ConclusionThis case provides an excellent example of SBO related to WS. In the video, the management of this complex situation is shown. In these cases, splenectomy represents a valuable option.
