Pituitary Stalk Thickening

Abstract Little has been reported on the safety and efficacy of pituitary biopsy in the pediatric population for suspected germinoma. An updated review is needed. Patients who underwent biopsy (endoscopic endonasal vs. open craniotomy) for isolated pituitary stalk thickening were identified. Age, pre- and post-operative endocrine status, surgical approach, length of surgery, estimated blood loss, surgical morbidity, length of ICU stay, total length of stay, and pathology reports were reviewed. Nine patients met inclusion criteria. Germinoma diagnosis was rendered in 7 of 9 patients; 1 patient required two biopsy attempts. Two-patients had histology consistent with inflammation and a subsequently self-limited disease course. Average operative time, blood loss, ICU stay and overall length of stay was just over 2 h, 28 mL, 1.6 days and 3.7 days respectively. There were no intraoperative complications and all patients were discharged home. One patient developed new diabetes insipidus post-operatively. Patients who underwent endoscopic biopsy had decreased operative times and shorter hospitalizations. Biopsy for isolated pituitary stalk thickening for suspected germinoma is generally safe with high diagnostic utility. Importantly, 22% of presumed germinomas on imaging yielded alternative diagnoses on biopsy, adding support for pathology-proven data to guide treatment in relevant cases.

OBJECTIVE Odontogenic ventral brainstem compression can be a source of significant morbidity in patients with craniocervical disease. The most common methods for odontoidectomy are the transoral and endoscopic endonasal routes. In this study, the authors investigated the use of an institutional protocol for endoscopic transnasal/transoral odontoidectomy in the pediatric population. METHODS From 2007 to 2017, a multidisciplinary institutional protocol was developed and refined for the evaluation and treatment of pediatric patients requiring odontoidectomy. Preoperative assessment included airway evaluation, a sleep study (if indicated), discussion of possible tonsillectomy/adenoidectomy, and thorough imaging review by the neurosurgery and otolaryngology teams. Further preoperative anesthesia consultation was obtained for difficult airways. Intraoperatively, adenoidectomy was performed at the discretion of otolaryngology. The odontoidectomy was performed as a combined procedure. Primary posterior pharyngeal closure was performed by the otolaryngologist. The postoperative protocol called for immediate extubation, advancement to a soft diet at 24 hours, and no postoperative antibiotics. Outcome variables included time to extubation, operative time, estimated blood loss, hospital length of stay, and postoperative complications. RESULTS A total of 13 patients underwent combined endoscopic transoral/transnasal odontoid resection with at least 3 years of follow-up. All patients had stable to improved neurological function in the postoperative setting. All patients were extubated immediately after the procedure. The average operative length was 201 ± 46 minutes, and the average estimated blood loss was 44.6 ± 40.0 ml. Nine of 13 patients underwent simultaneous tonsillectomy and adenoidectomy. The average hospital length of stay was 6.6 ± 5 days. The first patient in the series required revision surgery for removal of a small residual odontoid. One patient experienced pharyngeal flap dehiscence requiring revision. CONCLUSIONS A protocolized, institutional approach for endoscopic transoral/transnasal odontoidectomy is described. The use of a combined, multidisciplinary approach leads to streamlined patient management and favorable outcomes in this complex patient population.

Abstract Background To compare the perioperative outcomes of transperitoneal laparoscopic (TLA), retroperitoneal laparoscopic (RLA), and robot-assisted transperitoneal laparoscopic (RATLA) adrenalectomy for adrenal tumors in our center. Methods Between April 2012 and February 2018, 241 minimally invasive adrenalectomies were performed. Cases were categorized based on the minimally invasive adrenalectomy technique. Demographic characteristics, perioperative information and pathological data were retrospectively collected and analyzed. Results This study included 37 TLA, 117 RLA, and 87 RATLA procedures. Any two groups had comparable age, ASA score, Charlson Comorbidity Index, and preoperative hemoglobin. The tumor size for RLA patients was 2.7 ± 1.1 cm, which was significantly smaller compared to patients who underwent TLA/RATLA (p = 0.000/0.000). Operative time was similar in any two groups, while estimated blood loss was lower for RATLA group (75.6 ± 95.6 ml) compared with the TLA group (131.1 ± 204.5 ml) (p = 0.041). Conversion to an open procedure occurred in only one (2.7%) patient in the TLA group for significant adhesion and hemorrhage. There were no significant differences between groups in terms of transfusion rate and complication rate. Length of stay was shorter for the RATLA group versus the TLA/RLA group (p = 0.000/0.029). In all groups, adrenocortical adenoma and pheochromocytoma were the most frequent histotypes. Conclusions Minimally invasive adrenalectomy is associated with expected excellent outcomes. In our study, the RATLA approach appears to provide the benefits of decreased estimated blood loss and length of stay. Robotic adrenalectomy appears to be a safe and effective alternative to conventional laparoscopic adrenalectomy.

Objective. To establish short-term surgical outcomes of three-port laparoscopic risk-reducing salpingo-oophorectomy (RRSO) in women with hereditary breast-ovarian cancer syndrome (HBOC). Methods. The medical records of all HBOC women that underwent laparoscopic RRSO between January 2001 and December 2010 were retrospectively reviewed. Demographic data, operative details, and short-term surgical outcomes were obtained and subjected to SAS. Statistical univariate and multivariate analyses were performed. Results. 358 patients met study criteria with 277 (77.4%) carrying a documented BRCA mutation. The predominant technique utilized three ports (two 5 mm and one 10/12 mm), a 5 mm laparoscope and a 5 mm Ligasure pulsatile bipolar device. Mean operative time was 58.3 minutes (SD 22.6, 26.0–197.0), significantly affected by BMI greater than 30 (P<0.0001) and status of adhesions (P=0.001). Estimated blood loss (EBL) was negligible in 96.9% of cases. Seven patients required conversion to laparotomy. No major intraoperative complications were recorded. One-night hospital admission rate was less than 2.0% while postoperative complication rate was 3.1%. Malignancy was revealed in 14 patients (3.9%). Conclusion. In HBOC population, three-port laparoscopic RRSO is a simple, reproducible, and safe procedure with low conversion rate, short operative time, minimal EBL, low surgical morbidity, and rapid postoperative recovery.

Background. Craniosynostosis is the premature fusion of one or more cranial sutures that produce abnormal head shape. Plagiocephaly is a general term that describes unilateral flattening of the anterior or posterior quarter of the cranium. Anterior plagiocephaly is almost always due to unilateral coronal synostosis. Early surgical treatment is the best option for these patients. The aim of this study was to investigate the surgical correction results of unicoronal craniosynostosis with frontal bone symmetrization and staggered osteotomies. Methods. All unicoronal craniosynostosis cases treated surgically from 2013 to 2016 at our hospital, with frontal bone symmetrization and staggered osteotomies and fronto-orbital advancement, were reviewed. The following variables were analyzed: sex, age, weight, hospital stay time, ICU stay time, per os (PO) starting time, anesthetic time, estimated blood loss volume (ml), estimated blood loss as percentage of total volume, surgical complication, follow-up time, and Whitaker grade. All data were analyzed with SPSS. Results. The study consisted of 33 patients (19 females, 14 males). Average age was 10.24 months, average weight was 8.97 Kg, average hospital stay time was 7.84 days, average ICU stay time was 1.69 days, average PO starting time was 1.24 days after surgery, average anesthetic time was 397.72 minutes, average estimated blood loss was 213.78 ml, and estimated blood loss as percentage of total volume was 31.69%. One case (3.03%) needed reoperation and two cases had postoperative seizure. No mortality was seen. Conclusion. It is supposed that surgical correction of unicoronal craniosynostosis with frontal bone symmetrization and staggered osteotomies results in lower blood loss, lower complication rate and reoperation, and more durable results.

Abstract BACKGROUND: The length of construct can potentially influence perioperative risks in adult spinal deformity (ASD) surgery. A head-to-head comparison between open and minimally invasive surgery (MIS) techniques for treatment of ASD has yet to be performed. OBJECTIVE: To examine the impact of MIS approaches on construct length and clinical outcomes in comparison to traditional open approaches when treating similar ASD profiles. METHODS: Two multicenter databases for ASD, 1 involving MIS procedures and the other open procedures, were propensity matched for clinical and radiographic parameters in this observational study. Inclusion criteria were ASD and minimum 2-year follow-up. Independent t-test and chi-square test were used to evaluate and compare outcomes. RESULTS: A total of 1215 patients were identified, with 84 patients matched in each group. Statistical significance was found for mean levels fused (4.8 for circumferential MIS [cMIS] and 10.1 for open), mean interbody fusion levels (3.6 cMIS and 2.4 open), blood loss (estimated blood loss 488 mL cMIS and 1762 mL open), and hospital length of stay (6.7 days cMIS and 9.7 days open). There was no significant difference in preoperative radiographic parameters or postoperative clinical outcomes (Owestry Disability Index and visual analog scale) between groups. There was a significant difference in postoperative lumbar lordosis (43.3° cMIS and 49.8° open) and pelvic incidence-lumbar lordosis correction (10.6° cMIS and 5.2° open) in the open group. There was no significant difference in reoperation rate between the 2 groups. CONCLUSION: MIS techniques for ASD may reduce construct length, reoperation rates, blood loss, and length of stay without affecting clinical and radiographic outcomes when compared to a similar group of patients treated with open techniques.

Total pelvic exenteration is a highly morbid procedure performed for locally advanced pelvic malignancies. We describe our experience with three patients who underwent robotic total pelvic exenteration with laparoscopic rectus flap and compare perioperative characteristics to our open experience. Demographic, tumor, operative, and perioperative factors were examined with descriptive statistics reported. Mean operative times were similar between the two groups. When compared to open total pelvic exenteration cases(n=9), median estimated blood loss, ICU stay, and hospital stay were all decreased. These data show robotic pelvic exenteration with laparoscopic rectus flap is technically feasible. The surgery was well tolerated with low blood loss and comparable operative times to the open surgery. Further study is needed to confirm the oncologic efficacy and the suggested improvement in surgical morbidity.

Object Multiple surgical procedures have been described for the management of isolated nonsyndromic sagittal synostosis. Minimally invasive techniques have been recently emphasized, but these techniques necessitate the use of an endoscope and postoperative helmeting. The authors assert that a safe and effective, more “minimalistic” approach is possible, avoiding the use of endoscopic visualization and routine postoperative application of a cranial orthosis. Methods A single-institution cohort analysis was performed on 18 cases involving infants treated for isolated nonsyndromic sagittal synostosis between 2008 and 2010 using a nonendoscopic, minimally invasive calvarial vault remodeling (CVR) procedure without postoperative helmeting. The surgical technique is described. Variables analyzed were: age at time of surgery, sex, estimated blood loss (EBL), operative time, intraoperative complications, postoperative complications, length of stay, pre- and postoperative cephalic index (CI), clinical impressions, and results of a 5-question nonstandardized questionnaire administered to patient caregivers regarding outcome. Results Eleven male and 7 female infants (mean age 2.3 months) were included in the study. The mean duration of follow-up was 16.4 months (range 6–38 months). The mean procedural time was 111 minutes (range 44–161 minutes). The mean length of stay was 2.3 days (range 2–3 days). The mean EBL in all 18 patients was 101.4 ml (range 30–475 ml). One patient had significant bone bleeding resulting in an EBL of 475 ml. Excluding this patient, the mean EBL was 79.4 ml (range 30–150 ml). There were no deaths or intraoperative complications; one patient had a superficial wound infection. The mean CI was 69 preoperatively versus 79 postoperatively, a statistically significant difference (p < 0.0001). Two patients were offered helmeting for suboptimal surgical outcome; one family declined and the single helmeted patient showed improvement at 2 months. No patient has undergone further surgery for correction of primary deformity, secondary deformities, or bony irregularities. Complete questionnaire data were available for 14 (78%) of the 18 patients; 86% of the respondents were pleased with the cosmetic outcome, 92% were happy to have avoided helmeting, 72% were doubtful that helmeting would have provided more significant correction, and 86% were doubtful that further surgery would be necessary. Small, palpable, aesthetically insignificant skull irregularities were reported by family members in 6 cases (43%). Conclusions The authors present a nonendoscopic, minimally invasive CVR procedure without postoperative helmeting. Their small series demonstrates this to be a safe and efficacious procedure for isolated nonsyndromic sagittal synostosis, with improvements in CI at a mean follow-up of 16.1 months, commensurate with other techniques, and with overall high family satisfaction. Use of a CVR cranial orthosis in a delayed fashion can be effective for the infrequent patient in whom this approach results in suboptimal correction.

Abstract BACKGROUND: The minimally invasive lateral retroperitoneal approach for lumbar fusions is a novel technique with good results, but also with significant sensory and motor complications. OBJECTIVE: To present the early results of a modified surgical technique, in which the psoas muscle is dissected under direct visualization. METHODS: Thirteen consecutive patients with L4-5 or L3-4 pathology were prospectively followed after being treated using a minimally invasive lateral approach with direct exposure of the psoas muscle before dissection. There were 7 woman and 6 men with a mean age of 52.3 years. Perioperative parameters like operative time, estimated blood loss, and length of stay, were noted. Pain, paresthesia, and motor weakness, as well as any other complications, were evaluated at 2 weeks and 3 months postoperatively. RESULTS: The mean operative time, estimated blood loss, and length of stay were 163 minutes, 126 mL, and 3 days, respectively. One patient exhibited anterior thigh pain and paresthesia at 2 weeks, both of which resolved by 3 months. Two patients experienced superficial wound infections that healed with antibiotics. The genitofemoral nerve was identified and protected in 7 patients; in 4 patients, it had a more posterior anatomic location than expected. The femoral nerve was not exposed or detected in the operative field by neuromonitoring, nor were there any symptoms related to a femoral nerve injury in any patient. CONCLUSION: Dissection of the psoas muscle under direct visualization during the minimally invasive lateral approach may provide increased safety to the genitofemoral and femoral nerves.

Thoracoabdominal Incision

The thoracoabdominal incision was first described in 1946 as an approach to concomitant abdominal, retroperitoneal, and thoracic injuries. In urology, this technique was popularized in 1949 for the resection of large renal tumours. Today, it is reserved for complex cases where optimal exposure of the renal hilum and adrenal and superior pole of the kidney is necessary. We present four consecutive cases in which this approach was taken by a single surgeon at our tertiary surgical centre. The outcomes, postoperative course, and pathology are described. We provide a comprehensive literature review and outline the indications, advantages, and disadvantages of this approach. Objectives. To present a case series outlining the efficacy and safety of the thoracoabdominal incision in complex oncologic procedures in urology. Methods. Four cases utilizing the thoracoabdominal incision, performed by a single surgeon at our tertiary care center, were reviewed. Case history, preoperative imaging, intraoperative experience, postoperative course, final pathology, and complications were examined. A thorough literature review was performed and comparison made with historical cohorts for estimated blood loss, length of stay, and complications encountered versus other common surgical approaches. The indications, advantages, and disadvantages of the thoracoabdominal approach were outlined. Results. All patients had large retroperitoneal masses of varying complexity, requiring maximal surgical exposure. Surgery was straightforward in all cases, without any significant perioperative or postoperative complications. Postoperative pain, length of hospital stay, estimated blood loss, and analgesia requirements were all similar to open and mini-flank approaches in review of historical case series cohorts. Laparoscopic approaches had lower estimated blood loss and length of stay. Conclusions. The thoracoabdominal approach is rarely utilized in urological surgery, due to the perceived morbidity in violating the thoracic cavity. These cases outline the benefit of the thoracoabdominal approach in select cases requiring maximal surgical exposure, and the generally benign postoperative course that appropriately selected patients may hope to endure. Postoperative pain, length of hospital stay, estimated blood loss, and analgesia requirements can be expected to be similar open and mini-flank approaches. As expected, laparoscopic approaches had lower estimated blood loss and length of stay.
