Abstract
Schwannomas localized in the sacrum are relatively infrequent, accounting for 1-5% of all spinal axis schwannomas; they present with vague symptoms or are symptomless, so often grow to a considerable size before detection. Sacral schwannomas occasionally present with enormous dimensions, and these tumors are termed giant sacral schwannomas. However, their surgical removal is challenging owing to an abundant vascularity. The present study retrospectively analyzed the clinical and follow-up data of a patient with a giant sacral schwannoma. The patient experienced numbness in the left buttock and lower extremity, with radiating pain in the sole of the foot that had persisted for 3 years. A presacral mass was found by computed tomography examination 6 months after the stool had become thin. A tumor resection was performed using the anterior abdominal approach. A schwannoma was diagnosed by postoperative pathology. The postoperative course was uneventful, with the complete resolution of symptoms during the 21-month clinical follow-up. Overall, the present study reports the case of a giant sacral schwannoma with pelvic pain that was resected without complications and also discusses its successful management. Additionally, the study presents a systematic review of the literature. We consider that the surgical treatment of giant sacral schwannomas with piecemeal subtotal excision can achieve good outcomes, avoiding unnecessary neurological deficits.

Abstract
BACKGROUND Research on laparoscopic schwannoma resection (LSR) in the lateral pelvic space (LPS) remains limited. This study aimed to compare the short-term and oncological outcomes of LSR and conventional open schwannoma resection (OSR). METHODS Clinical data of 38 patients with lateral pelvic schwannomas were retrospectively collected. LSR in the LPS was based on fascial-oriented techniques. Operation-related results, neurological function, and oncological outcomes were compared. RESULTS A total of 38 patients were enrolled, including 18 and 20 patients who underwent LSR and OSR, respectively. The baseline characteristics showed no significant differences between the groups. The median blood loss and incision length in the LSR group were significantly lower (40.0 vs. 300 mL, 4.5 vs. 15 cm, P < 0.001). The LSR group showed less time to the first flatus (2.0 vs. 3.0 days, P = 0.029), time to pull drainage (5.0 vs. 6.0 days, P = 0.042), time to pull catheter (3.0 vs. 4.0 days, P = 0.027), and postoperative hospital stay (6.0 vs. 8.0 days, P = 0.048). The LSR group also showed fewer postoperative complications than the OSR group, although the difference was not significant (40.0% vs. 16.7%, P = 0.113). At a median follow-up of 36 months, no local recurrence was observed. CONCLUSIONS Fascial-oriented laparoscopic resection of schwannomas in the LPS is feasible without compromising oncological safety. LSR shows clear advantages, most notably small incisions, less blood loss, and quick recovery, as well as potential benefits of neurological function.

Abstract
Peripheral nerve sheath tumors (PNST) of the retroperitoneum are rare and are often treated by general surgeons dealing with retroperitoneal cancers. However, resection without the correct microsurgical technique can cause permanent neurological deficits and pain. Here, we discuss our interdisciplinary approach based on the integration of expertise from neurosurgery and abdominal surgery, allowing for both safe exposure and nerve-sparing microsurgical resection of these lesions. We present a series of 15 patients who underwent resection of benign retroperitoneal or pelvic PNST at our institution. The mean age of patients was 48.4 years; 67% were female. Tumors were 14 schwannomas and 1 neurofibroma. Eight patients (53%) reported neurologic symptoms preoperatively. The rate of complete resection was 87% (n = 13); all symptomatic patients showed improvement of their preoperative symptoms. There were no postoperative motor deficits; one patient (7%) developed a permanent sensory deficit. At a mean postoperative follow-up of 31 months, we observed no recurrences. To our best knowledge, this is the second-largest series of benign retroperitoneal PNST consistently managed with microsurgical techniques. Our experience confirms that interdisciplinary management allows for safe treatment of these tumors with good neurological and oncological outcomes.

Abstract
Schwannoma is a type of tumor originating from Schwann cells of peripheral
nerves. In this study, we report a rare case of two giant connected
retroperitoneal schwannomas. The patient presented to our department with a
1-day history of abdominal pain and without other symptoms. There were no
abnormalities in the patient’s tumor markers. Abdominal plain computed
tomography (CT) revealed two (combined) retroperitoneal masses appearing as soft
tissue-density shadows with uneven internal density, cystic low-density shadows,
and patchy calcification shadows. The larger mass measured approximately
12.0 cm × 12.3 cm in size. The tumors were completely excised by a reasonable
surgical approach while the surrounding organs closely related to the tumor were
preserved. Postoperative pathology confirmed that the tumors were benign
schwannomas. In the 18-month follow-up, the patient had no recurrences and was
asymptomatic. We summarize the diagnosis and treatment of two rare combined
giant retroperitoneal schwannomas in a single patient. Laparotomy for the
management of retroperitoneal giant schwannomas may be safe and effective.

Abstract
The aim of the present study was to investigate the feasibility of da Vinci robotic surgery in the treatment of presacral tumors, and to observe its efficacy and safety. Between March 2016 and April 2019, 12 patients with presacral nerve sheath tumors underwent da Vinci robotic surgery, and the integrity of the tumor resection, surgical duration, pre- and postoperative visual analog scale (VAS) score, intra- and postoperative blood losses, postoperative bedtime, hospital stay and complications were observed. The tumor was completely removed in all 12 patients, the surgical duration ranged between 76 and 245 min (mean, 106.08 min) and the intraoperative blood loss was 76-145 ml (mean, 101.67 ml). The average preoperative VAS score of the patients was 3.25, and the average VAS score at 1 week, 1 month and 3 months post operation were 1.08, 0.42 and 0.08, respectively. All patients were out of bed on the second day after surgery, and the postoperative drainage was 10-50 ml (mean, 33.50 ml). The patients were hospitalized for 3-5 days (mean, 3.92 days). No complications occurred peri- or postoperatively, and wound pain was the main source of postoperative discomfort. In conclusion, the da Vinci robot can be applied to presacral nerve sheath tumors with high surgical safety, low-level bleeding, a rapid recovery and a short hospital stay, making it worthy of further study.

Abstract
RATIONALE Retroperitoneal schwannomas are very rare and may grow very close to major abdominal vessels. Since the surgical approach to the retroperitoneal space may be complex due to surrounding vital organs, including major vessels, laparoscopic surgery is challenging and has only been recently adopted. Here, we report a case of laparoscopic resection of a large retroperitoneal schwannoma attached to large vital vessels. PATIENT CONCERNS A 62-year-old woman presented with a chief complaint of pain in the lower right limb with consequent claudication, which had lasted for approximately 1 year. DIAGNOSES Magnetic resonance imaging revealed a solid oval mass measuring 45 × 32 × 39 mm, located medially to the right iliopsoas muscle at the level of the intersomatic space between the 5th lumbar vertebra and the 1st sacral vertebra. This mass was inhomogeneously hypointense in T2 due to the presence of cystic areas, with intense and inhomogeneous contrast enhancement, compatible with the diagnosis of a schwannoma. The mass compressed the inferior caval vein near its bifurcation and the right common iliac vein, anteriorly dislocating the ipsilateral iliac arterial axis. INTERVENTIONS A multidisciplinary team skilled in vascular and pelvic laparoscopy was involved. The patient underwent laparoscopic surgery via an anterior transperitoneal approach with right adnexectomy and radical excision of the tumor. The surgery lasted 120 minutes without intraoperative complications. Blood loss was less than 100 mL. The histologic diagnosis was a benign Schwannoma; grade I according to World Health Organization classification. OUTCOMES The postoperative course was uneventful. At the 10-month follow-up, the patient had no recurrences and was asymptomatic. LESSONS Laparoscopic removal of large retroperitoneal schwannomas, even if attached to major vital vessels, is feasible and safe when performed by experienced surgeons.

Abstract
OBJECTIVE Giant presacral schwannomas are rare sacral tumors found in less than 1 of every 40,000 hospitalizations. Current management of these tumors is based solely upon case reports and small case series. In this paper the authors report the results of a systematic review of the available English literature on presacral schwannoma, focused on identifying the influence of tumor size, tumor morphology, surgical approach, and extent of resection (EOR) on recurrence-free survival and postoperative complications. METHODS The medical literature (PubMed and EMBASE) was queried for reports of surgically managed sacral schwannoma, either involving 2 or more contiguous vertebral levels or with a diameter ≥ 5 cm. Tumor size and morphology, surgical approach, EOR, intraoperative and postoperative complications, and survival data were recorded. RESULTS Seventy-six articles were included, covering 123 unique patients (mean age 44.1 ± 1.4 years, 50.4% male). The most common presenting symptoms were leg pain (28.7%), lower back pain (21.3%), and constipation (15.7%). Most surgeries used an open anterior-only (40.0%) or posterior-only (30%) approach. Postoperative complications occurred in 25.6% of patients and local recurrence was noted in 5.4%. En bloc resection significantly improved progression-free survival relative to subtotal resection (p = 0.03). No difference existed between en bloc and gross-total resection (GTR; p = 0.25) or among the surgical approaches (p = 0.66). Postoperative complications were more common following anterior versus posterior approaches (p = 0.04). Surgical blood loss was significantly correlated with operative duration and tumor volume on multiple linear regression (both p < 0.001). CONCLUSIONS Presacral schwannoma can reasonably be treated with either en bloc or piecemeal GTR. The approach should be dictated by lesion morphology, and recurrence is infrequent. Anterior approaches may increase the risk of postoperative complications.
