We report a case of a robotic-assisted excision of a retrocaval ancient schwannoma. A 40-year-old female presented with generalized weakness and abdominal pain that led to the diagnosis of a retroperitoneal mass adjacent to the pancreas and inferior vena cava. Because of the clinical, imaging, and needle biopsy findings, the patient underwent an elective robotic-assisted retroperitoneal exploration. We provide an overview of the pathology and highlight the significance of utilizing a minimally invasive approach for excision of retroperitoneal masses.

“…2 Our case, a schwannoma, is a benign tumour which arises from Schwann cells. 4,5 Alongside other neurogenic entities they account for 10% of pre-sacral lesions. 2 The majority are benign; 5-18% are associated with Neurofibromatosis I, which may undergo malignant changes.…”

BackgroundPost‐operative complications following rectal resection pose significant health and cost implications for patients and health providers. The objective of this study is to review the associated cost of complications following rectal resection. This included reporting on the proportion and severity of these complications, associated length of stay and surgical technique used. Studies were sourced from Embase OVID, MEDLINE OVID (ALL) and Cochrane Library databases by utilizing a search strategy.MethodsThis search contained studies from 1 January 2010 until 13 February 2019. Studies were included from the year 2010 to account for the implementation of enhanced recovery after surgery protocols. Studies that reported the financial cost associated with complications were included. Any indication for rectal resection was considered. Data was extracted into a formatted table and a narrative synthesis was performed.ResultsWe identified 13 eligible studies for inclusion. There was strong evidence to suggest that complications are associated with increased costs. There was considerable variation as to the costs attributable to complications ($1443 (P < 0.001) to $17 831 (P < 0.0012), n = 12). The presence of complications was associated with an increased length of stay (5.54 (P‐value not given) to 21.04 (P < 0.0001) days, n = 7). There was significant variation in the proportion of complications (6.41 to 64.71%, n = 8). Weak evidence existed around surgical technique used and the associated cost of complications. There was considerable heterogeneity among included studies.ConclusionsComplications following rectal resection increased health costs. Costs should be standardized and provide a clear methodology for their calculation. Complications should be standardized and include a grading of severity.

“…Generally, schwannomas are less than 5cm in diameter. But retroperitoneum is a nonrestrictive space which allows the tumors to reach a large size over a long time of growth (1). According to our search on Pubmed, we found out about 30 cases on giant retroperitoneal schwannoma.…”

“…Those in pararenal space are even rarer. Although most schwannomas are <5 cm in diameter, retroperitoneal schwannomas are able to grow into a large size in such a non-restrictive space (1). They are mostly asymptomatic until they grow too large to cause compression, which is usually ambiguous pain.…”

Giant posterior pararenal schwannoma: A�case report and review of literature

Schwannomas, arising from Schwann cells of peripheral nerve sheaths, are primarily benign tumors. They are rarely found in the retroperitoneal space. To date, ~30 cases on giant retroperitoneal schwannomas have been reported. Those with a location of pararenal space are even rarer. Clinically, they are often misdiagnosed as malignancies. In the present study, a case of a 35-year-old woman with a giant schwannoma measuring 13 × 8.5 × 6.5 cm in the posterior pararenal space of left retroperitoneum was presented, which was thought to be a malignant tumor from the result of computed tomography scan. Later postoperative pathology and immunohistochemistry were consistent with benign schwannoma. To the best of our knowledge, this was the largest posterior pararenal schwannoma reported in literature. It is significant to report this case, and summarize the characteristics, diagnosis, treatment and prognosis of the similar cases. Furthermore, a brief review of the previously published cases in literature is provided.
