"Wandering spleen" as a rare cause of recurrent abdominal pain: a systematic review

Wandering spleen causing small bowel obstruction: Laparoscopic surgical treatment (with video)

INTRODUCTION

Wandering 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 CASE

We 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.

DISCUSSION

WS 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.

CONCLUSION

This 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.

Diagnosis and treatment of splenic torsion in children: preoperative thrombocytosis predicts splenic infarction

Background

Pediatric splenic torsion is a rare entity, and the most common cause is wandering spleen. This study aimed to summarize our clinical experience in the diagnosis and surgical treatment pediatric patients with splenic torsion, and to use preoperative thrombocytosis as a preoperative predictive factor for splenic infarction.

Methods

From January 1st, 2016 to December 31st, 2021, 6 children diagnosed as splenic torsion were included. All patients were surgically treated and followed up. The clinical data was collected including clinical presentations, laboratory tests, imaging results, surgical procedures, and prognosis. Clinical experience of diagnosis and surgical treatment were summarized.

Results

There were 4 females and 2 males, with median age at surgery 102.6 (range 9.4–170.7) months. Abdominal pain and abdominal mass were the most common presentations. The diagnosis of splenic torsion depended on imaging studies, and adjacent organ involvement (gastric and pancreas torsion) was observed on contrast CT in one patient. Five patients were diagnosed as torsion of wandering spleen, and one was torsion of wandering accessory spleen. Emergent laparoscopic or open splenectomy was performed in all patients. Pathology revealed total splenic infarction in 4 patients, partial infarction in 1 patient, and viable spleen with congestion and hemorrhage in 1 patient. Preoperative platelet counts were elevated in all 4 patients with splenic infarction, but normal in the rest 2 with viable spleen. Postoperative transient portal vein branch thromboembolism occurred in one patient.

Conclusions

Imaging modalities are crucial for the diagnosis of pediatric splenic torsion and adjacent organ involvement. Preoperative thrombocytosis may predict splenic infarction. Spleen preserving surgery should be seriously considered over splenectomy in patients with a viable spleen.

Splenectomy for Torsion of a Wandering Spleen in a Patient with Myeloproliferative Disease

We herein report a rare case of torsion of a wandering spleen in a patient with myeloproliferative disease. A 66-year-old Japanese woman presented to our hospital with abdominal pain and a fever. She had a medical history of polycythemia and secondary myelofibrosis. Abdominal enhanced computed tomography showed an enlarged spleen without enhancement in the lower pelvic region. The clinical diagnosis was severe torsion of a wandering spleen in a patient with myeloproliferative disease, necessitating surgical intervention. Splenectomy was performed after de-rotating to revascularize the spleen. After the operation, the platelet count gradually increased, and aspirin was administered to prevent thrombosis.

The left gastro-omental vessels are able to maintain the entire spleen blood supply

The spleen is supplied by blood flow through the splenic artery and vein. The purpose of this communication is to report an ectopic spleen supplied only by reverse flow through the left gastro-omental vessels. A 14-year-old boy presented with pelvic splenomegaly supplied only by the left gastro-omental artery and veins connected to the inferior polar vessels, which were the only vessels communicating with the spleen. After detorsion of the spleen and splenopexy, the spleen returned to normal dimensions. The patient had uneventful follow-up. In conclusion, the left gastroepiploic vessels are able to maintain the entire spleen blood supply.

Torsion of spleen and portal hypertension: Pathophysiology and clinical implications

The displacement of spleen from its normal location to other places is known as wandering spleen (WS) and is a rare disease. The repeated torsion of WS is due to the presence of long pedicle and absence/laxity of anchoring ligaments. A WS is an extremely rare cause of left-sided portal hypertension (PHT) and severe gastric variceal bleeding. Left-sided PHT usually occurs as a result of splenic vein occlusion caused by splenic torsion, extrinsic compression of the splenic pedicle by enlarged spleen, and splenic vein thrombosis. There is a paucity of data on WS-related PHT, and these data are mostly in the form of case reports. In this review, we have analyzed the data of 20 reported cases of WS-related PHT. The mechanisms of pathogenesis, clinico-demographic profile, and clinical implications are described in this article. The majority of patients were diagnosed in the second to third decade of life (mean age: 26 years), with a strong female preponderance (M:F = 1:9). Eleven of the 20 WS patients with left-sided PHT presented with abdominal pain and mass. In 6 of the 11 patients, varices were detected incidentally on preoperative imaging studies or discovered intraoperatively. Therefore, pre-operative search for varices is required in patients with splenic torsion.

Surgical Approach of Wandering Spleen in Infants and Children: A Systematic Review

Introduction: Splenopexy has been proposed as the treatment of choice in case of wandering spleen (WS). We report our experience and review the current literature focusing on surgical management and outcomes of children affected by WS. Materials and Methods: Data regarding demographics, clinical manifestations, diagnosis, and treatment of children treated for WS at our Institution were analyzed. Systematic review was registered on Prospero (CRD42018089971). Scientific databases were searched using defined keywords. Articles were selected using predefined exclusion and inclusion criteria. Analysis was conducted adding our center's cases. Results: One hundred sixty-six articles were included in the review, 197 cases were analyzed, 3 of which unpublished. Female/male ratio was 1.5:1 and median age at diagnosis was 8 years. Most frequent clinical manifestation was isolated abdominal pain (42.6%). Torsion of splenic pedicle was diagnosed in 56.3%. Among surgical procedures, 39% underwent splenopexy and 54.8% underwent splenectomy. In case of splenopexy, the most commonly used techniques were using of a mesh (45.5%) or creation of a retroperitoneal pouch (30.9%). In 48.2% of splenopexies, minimally invasive surgery (MIS) was used. Splenopexy was effective in 94.8% (88% considering only cases with a spleen torsion). Conclusion: WS is a rare condition potentially leading to torsion of the spleen. This entity has to be kept in mind as a differential diagnosis in case of abdominal pain. Splenopexy should be the treatment of choice; its success rate in terms of preserved spleens can be affected by the presence of a torted organ. Retroperitoneal pouch or mesh fixation are the most preferred techniques. Authors recommend MIS approach.

The likely association between wandering spleen and absent left kidney

Wandering spleen is a cause of acute surgical abdomen with serious consequences. It arises from an absence or weakness of the supporting suspensory splenic ligaments. There is often a delayed diagnosis due to its non-specific clinical presentation. This leads to stalled acquisition of confirmatory diagnostic imaging with resultant increased morbidity and mortality. Congenital or acquired absence of the left kidney results in loss of the splenorenal ligament, a key ligament to maintain normal splenic position in the abdomen. Two patients, one with OHVIRA (obstructed hemivagina ipsilateral renal anomaly) syndrome and another who underwent a left nephrectomy during infancy, developed a wandering spleen with acute splenic torsion in the setting of an absent left kidney. This case series aims to increase awareness to the likely predisposition for individuals with an absent left kidney to develop a wandering spleen.

Laparoscopic splenectomy for polysplenia with splenic torsion: a case report

Background

Polysplenia refers to the presence of two or more equal-sized spleens. Very rarely, one of the multiple spleens may develop torsion and infarction.

Case presentation

A 21-year-old woman presented with left upper quadrant pain, the cause of which could not be diagnosed. She returned to our hospital, 2 days later, without any pain improvement. Enhanced computed tomography showed splenic infarction and polysplenia. Initially, we could not identify the cause of the infarction and started conservative therapy, which did not result in any improvement. Hence, we performed a splenectomy, after securing informed consent. Because the patient was a young woman, we opted for a laparoscopic approach. During surgery, we identified the cause of the infarction as spleen pedicle torsion; the infarcted spleen was excised using an automated suturing device. We completed the laparoscopic surgery without converting it to an open laparotomy, and the patient was discharged 4 days later. This was a rare case of polysplenia with splenic torsion.

Conclusion

Laparoscopic splenectomy is minimally invasive and has cosmetic advantages. Thus, this approach may be considered as a treatment option for this condition.
