Stem Cells International 2019To report our experience in a compassionate use program for complex perianal fistula.
AIM
To report our experience in a compassionate use program for complex perianal fistula.
METHODS
Under controlled circumstances and approved by European and Spanish laws, a compassionate use program allows the use of stem cell therapy for patients with nonhealing diseases, mostly complex fistula-in-ano, who do not meet criteria to be included in a clinical trial. Candidates had previously undergone multiple surgical interventions that had failed. The intervention consisted of surgery (with closure of the internal opening or a surgical flap performance), followed by stem cell injection. Three types of cells were used for implant: stromal vascular fraction, autologous expanded adipose-derived, or allogenic adipose-derived stem cells. Healing was evaluated at 6 month follow-up. Outcome was classified as partial response or healing. Relapse was evaluated 1 year later. Maximum follow-up period was 48 months.
RESULTS
45 patients (24 male) were included; the mean age was 45 years, which ranged from 24 to 69 years. Since some of them received repeated doses, 52 cases were considered (42 fistula-in-ano, 7 rectovaginal fistulas, 1 urethrorectal fistula, 1 sacral fistula, and 1 hidradenitis suppurativa). Regarding fistula-in-ano, there were 18 Crohn's-associated and 24 cryptoglandular. 49 cases (94.2%) showed partial response starting 6.5 weeks of follow-up. 24 cases (46.2%) healed in a mean time of 5.5 months. A year later, all patients cured remained healed. No adverse effects related to stem cell therapy were reported.
CONCLUSION
Stem cells are safe and useful for treating anal fistulae. Healing can be achieved in severe cases.

BACKGROUND
At present, anastomotic fistula cannot be avoided after adenocarcinoma of the esophagogastric junction (AEG). Once the anastomotic leakage occurs, the posterior mediastinum and the left thoracic cavity are often seriously infected, which further impairs respiratory and circulatory function, heightening the danger of the disease course. The aim of this study was to identify the characteristics of superior anastomotic leakage after surgery for AEG and recommend corresponding treatment strategies to improve the diagnosis and treatment of superior anastomotic leakage after surgery for AEG.
METHODS
The clinical data of 57 patients with superior anastomotic leakage after surgery for AEG in the Affiliated Cancer Hospital of Zhengzhou University from January 2017 to March 2019 were retrospectively analyzed, including 27 cases referred from external hospitals and 30 cases at the Affiliated Cancer Hospital of Zhengzhou University. According to the diameter and risk level of anastomotic leakage, the high anastomotic leakage is divided into types I, II, III, and IV.
RESULTS
Patients with preoperative comorbidities or those treated with the transabdominal approach or laparoscopic surgery often had type I and type II anastomotic leakage; meanwhile, patients with preoperative comorbidities and sacral perforation or those treated with a thoracic and abdominal approach or open surgery often had type III and IV fistula. The difference between types I-II and types III-IV was statistically significant (P<0.05). The mortality rate of patients with type III and type IV leakage was 14.8% within 90 days after operation, while no deaths occurred among patients with type I and type II leakage, and the difference in mortality between the two groups was statistically significant (P<0.05).
CONCLUSIONS
After surgery for AEG, suitable treatment measures should be adopted according to the type of superior anastomotic leakage that occurs. Types III and IV superior anastomotic leakages are associated with higher mortality and require greater attention from surgeons.

Acquired Lumbosacral Spinal Dural Arteriovenous Fistula in Association with Degenerative Lumbosacral Disc Herniation and Spinal Canal Stenosis: Report of Two Cases and Review of the Literature.
The authors describe two cases harboring lumbosacral spinal dural arteriovenous fistulas (SDAVFs) manifested with nonspecific initial symptoms, leading to misdiagnosis and unnecessary procedures. A curvilinear flow void in the lumbar region and thoracic cord congestion with subtle perimedullary flow voids were detected on magnetic resonance imaging (MRI) in both patients. Contrast-enhanced magnetic resonance angiography and spinal angiography confirmed the SDAVFs in the lower lumbar and sacral region. Both fistulas were located at the same level of disc herniation and spinal canal stenosis and supplied by branches of the internal iliac arteries (i.e., iliolumbar and lateral sacral arteries) with cranial drainage from the dilated vein of the filum terminale, corresponding to a curvilinear flow void, to the perimedullary veins. The first case was successfully treated with embolization. Another case had recanalization of the fistula 4 months after endovascular treatment and was successfully treated with surgical interruption of the fistula. Our two case reports may provide additional evidence supporting an acquired etiology of SDAVFs, probably secondary to lumbosacral disc herniation and spinal canal stenosis. The authors also reviewed literature about preexistent lumbosacral SDAVFs associated with disc herniation and spinal canal stenosis. From our review, the level of SDAVFs in most patients is correlated with the level of disc herniation, spondylolisthesis, and/or spinal stenosis.

OBJECTIVE
To present 10 consecutive, standardized, and reproducible surgical steps allowing complete excision of deep endometriosis nodules infiltrating the parametrium and sacral roots.
DESIGN
Surgical video presenting the 10 surgical steps. Local institutional review board approval was not required for this video article, because the video describes a technique and the patient cannot be identified whatsoever.
SETTING
Endometriosis Center.
PATIENTS
Patients undergoing excision of deep endometriosis nodules of the parametrium and sacral roots.
INTERVENTION
The excision of deep endometriosis infiltrating the parametrium down to the sacral roots may be performed following 10 steps: complete ureterolysis and removal of ureteral stenosis; opening of the pararectal space in contact with the rectum in a sagittal plane; dissection caudally toward the rectovaginal space, section of the rectovaginal nodule in two separate blocks infiltrating the rectum and vagina, respectively, all the way down to the levator ani muscles; dissection of the presacral space and identification of the superior hypogastric plexus and hypogastric nerve; transverse incision of the peritoneum at the level of the promotorium, extended laterally above the origin of the hypogastric vessels; anterograde dissection of the hypogastric artery and identification of the hypogastric vein; anterograde dissection of the hypogastric vein and opening of Okabayashi space, followed by identification and, when required, ligation of hypogastric vein tributaries; dissection is extended behind the venous network with identification of the pyriform muscles and sacral roots S2, S3, and S4; anterograde dissection of the nerve network and inferior hypogastric plexus, up to the posterior limits of the deep endometriosis nodule; and excision of the deep endometriosis nodule from the posterior limit to the inferior limit in contact with the sacral roots, which should be released or shaved, then to the lateral limit in contact with the pyriform muscle and lateral pelvic wall. Additional steps may be required to remove adjacent infiltration of the vagina, rectum, bladder, or ureters. The movie does not reflect a similar approach in cases of isolated nodules of the sciatic nerves involving a specific lateral dissection plane between the external iliac vessels and the iliopsoas muscle.
MAIN OUTCOME MEASURES
Description of 10 successive surgical steps.
RESULTS
The 10-step procedure already has been employed in 70 women with deep endometriosis of the parametria involving sacral roots, in whom sensory or motor complaints were not completely relieved by continuous amenorrhea provided by contraceptive pill intake or gonadotropin-releasing hormone analogs. Baseline complaints included somatic pain (85.7%), severe bladder dysfunction (10%), or hydronephrosis (24.3%). Main localizations concerned sacral roots (95.7%), sciatic nerves (7.1%), mid/low rectum (87.1%), and bladder (21.4%). Operative time was 224 ± 94 minutes. Among postoperative complications, we recorded rectovaginal fistulae (14.3%), urinary tract fistulae (4.3%), and bladder dysfunction at 3 weeks (22.9%) and 12 months (5.7%) after the surgery.
CONCLUSIONS
Laparoscopic excision of deep endometriosis nodules of the parametria involving the sacral roots is a challenging procedure, requiring good anatomic and surgical skills. Teaching such a complex procedure is a delicate task. By following 10 sequential steps, the surgeon may reduce the risk of hemorrhage originating from the hypogastric venous network, preserve as much as possible autonomic nerves and organ function, and successfully excise deep endometriosis nodules. However, transection of the internal iliac artery and vein should not be systematic, as it may adversely affect the vascular supply of the pelvis. Transection of small pelvic splanchnic nerves should be performed only if they actually are included in fibrous nodules, as it may be followed by sexual, bladder, and rectal dysfunction or perineal sensory effects. Although the 10 steps attempt to standardize the surgical approach in a challenging localization of deep endometriosis, they are not mandatory and their use should be individualized.

BACKGROUND
Anterior sacral meningocele (ASM) is a rare congenital anomaly. It is characterized by herniation of the dura through a defect in the anterior sacrum. Rarely, however, it may extend to the rectal area through a rectothecal fistula with or without rectorrhea.
CASE DESCRIPTION
Here, we present a case of ASM associated with a rectothecal fistula and rectorrhea. Surgical closure of the ostium of the cyst through a posterior approach resulted in long-term improvement.
CONCLUSION
An ASM with both rectothecal fistula and rectorrhea is extremely rare.

Caudal regression syndrome (CRS) is a rare congenital disorder characterized by arrest of caudal spinal growth and associated with wide spectrum multisystemic anomalies. Herein, we presented a case of a newborn baby who did not pass meconium due to imperforated anus and was referred to the pediatric surgeon for urgent diverting loop colostomy. The conventional X-ray, abdominal ultrasound and abdominal pelvic magnetic resonance imaging (1.5 T) at 2-month-old age revealed right kidney agenesis, sacrococcygeal agenesis, vertebral bodies dysraphism and the spinal cord ends at D12-L1 with anterior and posterior bands of the terminating filaments. The diagnosis of CRS was confirmed. Through this case report, we hope to draw attention to this rare syndrome and the wide range of associated anomalies, also to consider this syndrome on the top of differential diagnosis list once the newborn has anorectal malformation mainly imperforated anus.

BACKGROUND
Inferior mesenteric arterioportal fistula (APF) is rare as only 35 case reports in the literature. We herein presented a case of simultaneously double cancer in the rectum and stomach with inferior mesenteric APF, which is the first case report by searching using PubMed. Combination of interventional embolization and surgical operation seemed to be optimal treatment for avoiding postoperative complications and the curability.
CASE PRESENTATION
A 66-year-old male with epigastric pain was admitted to a practitioner. He underwent a gastroscopy with biopsy, and cancer located in the lesser curvature of the gastric cardia was found. Enhanced CT did not reveal wall thickening of the stomach and distant metastases, but several swollen lymph nodes were observed in the right cardia. In the arterial phase, dilation of inferior mesenteric vein (IMV) and superior rectal artery (SRA) were noted, which raised suspicions of an arterioportal communication. Colonoscopy revealed a type 2 rectal tumor located 12 cm from the anal verge. The histological diagnosis of well-differentiated tubular adenocarcinoma was confirmed by biopsy. At a first step, we planned to perform a radiological embolization of inflow vessels to APFs except for SRA. Additionally, we determined the interval time of 1 month between the first low anterior rectal resection and the sequential gastrectomy for the purpose of decreasing portal pressure. The postoperative course was uneventful without hemorrhagic complications, and S-1 was taken internally 1 year as adjuvant chemotherapy for gastric cancer. The patient still lives without recurrence of this cancer with APF and portal vein thrombosis 2.5 years after the aforementioned surgeries.
CONCLUSION
Inferior mesenteric APF and/or arteriovenous fistula (AVF) would be consisted of the several inflow arteries as superior rectal, internal iliac, and median sacral arteries, and outflow veins as inferior mesenteric, internal iliac, and median sacral veins. To determine the therapeutic strategy for left-sided colorectal cancers with abnormal vessel communications of the pelvis, it is significant to comprehend distribution and component vessels of APF and/or AVF.

Review
The occurrence of pneumorrhachis (PR), defined as the presence of air within the spinal canal, presents a complex clinical picture with diverse etiological factors. We report an exceedingly rare case of PR arising from locally advanced rectal cancer accompanied by a pre-sacral abscess. This report aims to enhance awareness and understanding of rare causes of PR within the medical community, particularly among surgeons engaged in emergency procedures. The patient survived the acute phase of the disease through multiple surgical interventions and admission to the intensive care unit, but succumbed to cardiovascular complications three weeks later. We also offer a brief review of the literature concerning PR originating from the colorectal lumen.

We report the clinical course of a patient who developed a sacral radiation ulcer 19 years after treatment for cervical cancer. The patient's postoperative course after a free latissimus dorsi muscle flap transfer was favorable, but various late radiation complications, including rectal perforation, a rectal fistula, sacral necrosis, a rectointestinal fistula, and sacroiliac joint osteomyelitis, occurred within 11 years. Plastic surgeons who treat such ulcers need to know that patients may develop other serious radiation-related complications. Being aware of these complications will allow appropriate measures to be taken and aid decisions regarding future surgical strategies. More careful assessment of sacral necrosis and bone resection may have ameliorated some of the complications. When encountering similar patients, we believe that careful magnetic resonance imagery (MRI) and intraoperative evaluation are warranted, as sacral necrosis may be detectable in some patients.
