Laparoscopic splenectomy for a wandering spleen complicating gastric varices: report of a case

Successful treatment of floating splenic volvulus: Two case reports and a literature review

BACKGROUND

The floating spleen refers to the spleen moving away from the normal anatomical position to other parts of the abdominal cavity.

CASE SUMMARY

In this report, we describe two cases of torsion of floating spleen, which were successfully treated by laparoscopic partial splenectomy and retroperitoneal fixation of the residual spleen. The clinical characteristics of previously reported cases are also discussed.

CONCLUSION

In conclusion, laparoscopic partial resection of splenic volvulus infarction and extraperitoneal fixation of residual spleen are safe and reliable.

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.

Metachronous port site, muscular and subcutaneous metastases from a gastric adenocarcinoma: a case report and review of articles

Background

Port site metastasis (PSM) after curative gastrectomy for gastric cancer and muscular metastasis from gastric cancer are rare manifestations. Similarly, subcutaneous metastasis from gastric cancer is rare, and muscular and subcutaneous metastases are associated with poor prognosis. We report a case of long-term survival in a patient who underwent curative resection of gastric cancer and repeated recurrence of port site, muscular and subcutaneous metastases from gastric cancer, treated by resection.

Case presentation

A 75-year-old man was diagnosed with gastric cancer and referred to our department. Upper endoscopy demonstrated a 5-cm circumferential ulcerated lesion at the cardia. Biopsy findings showed a poorly differentiated tubular adenocarcinoma. He underwent laparoscopic total gastrectomy with lymph node dissection, and pathologic examination revealed a moderately differentiated tubular adenocarcinoma stage T4aN1M0 and IIIA according to the UICC (Union for International Cancer Control) classification. He refused adjuvant chemotherapy and was only carefully observed. Twenty-three months after the primary gastrectomy, computed tomography (CT) revealed an irregular mass near the port site wounds. Then the patient underwent mass resection, and the pathological diagnosis was consistent with metastatic adenocarcinoma, located in the subcutaneous tissue at the port site wounds. Thirteen months after the second surgery, CT revealed an enhanced mass in the abdominal wall. Positron emission tomography (PET) CT showed an elevated uptake in the rectus abdominis muscle and a standardized uptake value (SUV) of 3.1. The patient underwent another mass resection, and the pathological diagnosis was consistent with metastatic adenocarcinoma in the rectus abdominis muscle. Thirty-five months after the third surgery, CT revealed a mass in the left gluteal subcutaneous region. Furthermore, PET-CT revealed a 35-mm mass with an elevated SUV of 9.6. Another mass resection procedure was performed, and the pathological diagnosis was consistent with metastatic adenocarcinoma in the subcutaneous tissue. Since tumor cells were present at the resection margin, additional radiation therapy was performed. The patient has survived 78 months after primary gastrectomy.

Conclusion

The prognosis of muscular and subcutaneous metastases from gastric cancer is poor. However, if the metastatic tumor is solitary, surgical excision could be a feasible treatment option and might prolong survival.

Wandering spleen: a rare complication of sleeve gastrectomy

The spleen is an intraperitoneal organ typically located in the left upper quadrant. Ectopic ('wandering') spleen refers to the displacement of the spleen from its normal anatomical location to another region in the abdominal cavity or pelvis. It's a relatively rare condition with no clear aetiology. We present, here, a case of a wandering spleen following sleeve gastrectomy in a 23-year-old female patient, whose spleen, prior to this event, was demonstrated by imaging in a normal anatomical position. A splenectomy was performed, and after an uneventful postoperative period, the patient was discharged. No similar case description was found in the relevant medical literature. Possible causes and decision-making process are discussed. We conclude that the wandering spleen phenomenon should be considered in the differential diagnosis of patients presenting with abdominal pain and new abdominal mass following sleeve gastrectomy.

Torsion of a wandering spleen as a cause of portal hypertension and mesenteric varices: a rare aetiology

A wandering spleen is a condition characterized by excessive splenic mobility due to the mal-development or the laxity of its ligaments that leads to migration from its normal anatomical location. This condition renders its long mobile vascular pedicle liable to torsion and occasional infarction. Herein, we report a case of a 27-year-old nulliparous woman who presented with acute abdominal pain and a tender right-sided pelvi-abdominal mass. CT scan of the abdomen and pelvis revealed a torted, infarcted wandering spleen with portal hypertension and mesenteric varices that mandated an emergency splenectomy. Although there are a few reported cases describing the association of wandering spleen with portal hypertension and fundal varices, cases of mesenteric varices are extremely rare. To the best of our knowledge, this case is considered the third reported case of a wandering spleen which was subsequently complicated by portal hypertension and mesenteric varices that was managed effectively with splenectomy.
