Background: Thoracoscopic surgery has been increasingly used for a variety of indications. Posterior mediastinal tumors form an important component of a thoracic surgeon’s workload. This report represents a summary of our initial experience in thoracoscopic management of such tumors. Methods: We retrospectively reviewed the clinical and operative data from records over the study period. We also describe our usual perioperative management and surgical techniques. Results: A total of 11 patients, 8 being females, were operated during the period of 30 months. Seven were incidental findings, and chest pain was the commonest presentation in symptomatic patients. The mean age of the patients was 38.7 years; mean tumor diameter was 4.4 cm; eight had benign schwannoma, and no patient had a malignant tumor. Mean operative duration was 175.5 min; there were no conversions and no transfusion was required. Mean length of stay in the hospital was 5.6 days. There were no perioperative deaths or major complications. Three minor complications were recorded. Follow-up (4 to 18 months) was uneventful. Conclusions: Thoracoscopic management of posterior mediastinal tumors is feasible and safe.

Background: Cartilage repair algorithms use lesion size to choose surgical techniques when selecting a cartilage repair procedure. The association of fresh osteochondral allograft (OCA) size with graft survivorship and subjective patient outcomes is still unknown. Purpose: To determine if lesion size (absolute or relative) affects outcomes after OCA transplantation. Study Design: Cohort study; Level of evidence, 3. Methods: The study included 156 knees in 143 patients who underwent OCA transplantation from 1998 to 2014 for isolated femoral condyle lesions. The mean age was 29.6 ± 11.4 years, and 62.9% were male. The majority of patients (62.2%) presented for cartilage repair because of osteochondritis dissecans. The mean graft area, used as a surrogate for absolute size of the lesion, was 6.4 cm2 (range, 2.3-11.5 cm2). The relative size of the lesion was calculated as the tibial width ratio (TWR; ratio of graft area to tibial width) and affected femoral condyle ratio (AFCR; ratio of graft area to affected femoral condyle width) using preoperative radiographs. All patients had a minimum follow-up of 2 years. Further surgical procedures were documented, and graft failure was defined as revision OCA transplantation or conversion to arthroplasty. International Knee Documentation Committee (IKDC) pain, function, and total scores were obtained. Satisfaction with OCA transplantation was assessed. Results: The mean follow-up among patients with grafts remaining in situ was 6.0 years (range, 1.9-16.5 years). The OCA failure rate was 5.8%. Overall survivorship of the graft was 97.2% at 5 years and 93.5% at 10 years. No difference in postoperative outcomes between groups was found in absolute or relative size. Change in IKDC scores (from preoperative to latest follow-up) was greater for knees with large lesions compared to knees with small lesions, among all measurement methods. Overall satisfaction with the results of OCA transplantation was 89.8%. Conclusion: The size of the lesion, either absolute or relative, does not influence outcomes after OCA transplantation for isolated femoral condyle lesions of the knee.

BACKGROUND: The surgical treatment for non-tuberculous mycobacterial pulmonary disease (NTM-PD) has an important adjunctive role and reported outcomes have been generally good; however, the prognostic factors remain unclear.METHODS: Sixty-one patients with NTM-PD who underwent surgical resection for a therapeutic purpose from January 2000 to March 2017 at five affiliated institutions were enrolled. We explored the factors that influence complications and prognosis by retrospectively referring to the medical records.RESULTS: The mean age of the present cohort was 61.8 ± 11.4 years. The pathogen was Mycobacterium avium complex in 49 patients, M. abscessus in 5. The most common indications were refractory to medication in 39. The surgical techniques employed were lobectomy or further resection in 49, sublobar resection in 8, with video-assisted thoracoscopic surgery in 21. Sputum culture conversion rate was 95.1%. Univariate analysis of factors associated with deterioration revealed significant differences related to age (P = 0.025), pre-operative albumin level (P = 0.001) and development of postoperative complications (P = 0.037), while pre-operative albumin level alone was a significant factor in multivariate analysis (P = 0.009).CONCLUSION: Outcomes after resection were generally good in the present cases. Nutritional status, as indicated by albumin level, may affect prognosis after surgical treatment.

Object The authors sought to determine the long-term tumor control and side effects of Gamma Knife radiosurgery (GKRS) in patients with vestibular schwannomas (VS). Methods One hundred seventeen patients with VS underwent GKRS between January 1997 and February 2003. At the time of analysis, at least 5 years had passed since GKRS in all patients. The mean patient age was 60.9 years. The mean maximal tumor diameter was 1.77 ± 0.71 cm. The mean tumor volume was 1.95 ± 2.42 ml. Eighty-two percent of lesions received 1300 cGy and 14% received 1200 cGy. The median dose homogeneity ratio was 1.97 and the median dose conformality ratio was 1.78. Follow-up included MR imaging or CT scanning approximately every 6–12 months. Rates of progression to surgery were calculated using the Kaplan-Meier method. Results Of the 117 patients in whom data were analyzed, 103 had follow-up MR or CT images and 14 patients were lost to follow-up. Fifty-three percent of patients had stable tumors and 37.9% had a radiographically documented response. Imaging-documented tumor progression was present in 8 patients (7.8%), but in 3 of these the lesion eventually stabilized. Only 5 patients required a neurosurgical intervention. The estimated 1-, 3-, and 5-year rates of progression to surgery were 1, 4.6, and 8.9%, respectively. One patient (1%) developed trigeminal neuropathy, 4 patients (5%) developed permanent facial neuropathy, 3 patients (4%) reported vertigo, and 7 patients (18%) had new gait imbalance following GKRS. Conclusions Gamma Knife radiosurgery results in excellent local control rates with minimal toxicity for patients with VS. The authors recommend standardized follow-up to gain a better understanding of the long-term effects of GKRS.

New Treatment

Transoral incisionless fundoplication is a new treatment for patients with gastroesophageal reflux disease. We present our initial experience with 10 patients undergoing this procedure with varying past surgical histories. All procedures were performed under general nasotracheal anesthesia. RAND-36 and Visual Analog Scale symptom scores were collected at pre and postoperative appointments for a mean of 9.2 months. The mean procedure time was 68 minutes. There were no intraoperative or postoperative complications. Patients with prior pancreaticoduodenectomy had observed reduced working space due to prior distal gastrectomy and required additional insufflation due to no pyloric resistance to insufflation of the small bowel. The patient with prior fundoplication required additional time and force for fastener penetration of the resultant scar from the partially disrupted fundoplication. All patients were discharged within 23 hours of the procedure. Throughout the follow-up period, patients reported gradual changes in medication requirements and symptom scores. There were no late complications. Transoral incisionless fundoplication is technically safe in well-selected patients including those with prior esophageal and gastric surgery.

Cuff Repair

Background: Rotator cuff repair is one of the most common surgical procedures performed on the shoulder. Previous studies have indicated that pain and disability can vary significantly between patients with similarly appearing rotator cuff tears on diagnostic imaging. Prior literature has compared functional outcomes between operative and nonoperative treatments as well as variability in surgical techniques. However, few studies have examined postoperative outcomes based on patient factors such as sex. Purpose: To compare patient-reported outcomes after rotator cuff repair between men and women. Study Design: Cohort study; Level of evidence, 2. Methods: A total of 283 patients (153 male, 130 female) who underwent primary arthroscopic rotator cuff repair were included in this study; of those, 275 patients (97.2%) completed 1-year follow-up. Patient-reported pain visual analog scale (VAS), Veterans RAND 12-item Health Survey (VR-12 mental and physical components), American Shoulder and Elbow Surgeons (ASES), and Single Assessment Numeric Evaluation (SANE) scores were collected preoperatively and at 2 weeks, 6 weeks, 3 months, 6 months, and 1 year postoperatively using an electronic outcomes system. Results: Women reported higher VAS pain scores when compared with men preoperatively ( P < .01) and at 2 weeks ( P < .01), 6 weeks ( P < .01), and 3 months ( P = .02) postoperatively. Additionally, women experienced a greater overall change in the mean VAS score preoperatively when compared with 1 year postoperatively ( P < .01). The use of narcotic pain medication 2 weeks after surgery was greater in women ( P = .032). Women had significantly lower preoperative VR-12 mental scores ( P = .03) and experienced a greater increase in the mean VR-12 mental score preoperatively when compared with 1 year postoperatively ( P < .01). Men had higher ASES scores preoperatively ( P < .01) and at 3 months postoperatively ( P < .01). Women experienced a greater overall change in the ASES score preoperatively when compared with 1 year postoperatively ( P < .01). Conclusion: Women reported greater pain and decreased shoulder function compared with men during the initial 3 months after arthroscopic rotator cuff repair. There were no sex-based differences in patient-reported outcomes at 1-year follow-up. The results of this study indicate that there are sex-related differences in the early postoperative recovery of patients undergoing rotator cuff repair, contributing to postoperative expectations for both clinicians and patients alike.

Abstract The prevalence of growth hormone (GH)-secreting pituitary adenoma is around 11-13% of all pituitary adenomas. Giant GH-secreting pituitary adenomas (≥ 4 cm) are rare tumors, and its prevalence of among acromegalic patients is &lt;5%. This is a retrospective cohort study including patients with giant GH-secreting pituitary adenomas. The study population consisted of 10 patients (5 M/5 F). The mean age at diagnosis was 33.0±12.9 yrs (11-55 yrs). The mean delay between first symptom onset and diagnosis was 2.9 years. The most frequent symptoms were acral enlargement and facial changes (80%), followed by headache (70%) and visual deterioration (50%). One patient had epilepsy. Amenorrhea was presented in three females but obvious galactorrhea in two. The mean adenoma diameter was 42.6±4.7 mm (40-51 mm) at diagnosis. The vast majority of adenomas presented suprasellar extension (100%) or cavernous sinus invasion (80%). Cystic adenomas accounted for 50%. At presentation, mean GH and IGF-1 levels were 40.0±21.4 ng/mL (14.8-51.0) and 2.62±1.09 x ULN (1.08-3.96), respectively. Six patients presented with PRL cosecretion. At diagnosis maximal tumor diameter was not correlated with GH or IGF-1 levels. All patients underwent pituitary surgery as first-line treatment. Three cases were treated with an endoscopic approach and four cases with a microscopic approach. Transcranial approach was also employed in three cases. Postoperative mean GH and IGF-1 levels were 14.9±16.1 ng/mL (0.6-51.0) and 2.25.±0.82 x ULN (1.48-3.74), respectively. After first surgery, only one patient had more than 50% reduction in IGF-1 levels. Five patients (50%) underwent repeat surgery on two to three procedures because remission was not achieved. Postoperative somatostatin receptor ligands (SRLs) were used by all patients. Six patients were treated with dopamine agonist in combination with SRL. Six patients (60%) received postoperative radiotherapy. The mean follow-up period was 12.6±5.3 yrs (4-21 yrs). The mean GH and IGF-1 levels were 1.47±1.54 ng/mL (0.08-5.25) and 0.73±0.44 x ULN (0.08-1.56), respectively at the last visit. Residual adenoma was present at the last MRI in eight patients (mean diameter 9.0±3.6 mm). Panhypopituitarism rose from 10% at baseline to 30% at the last visit. During follow-up, one patient diagnosed breast cancer, while another diagnosed thyroid papillary cancer. Giant GH-secreting pituitary adenomas can have a clinically aggressive behavior with mass effect. Moreover, treatment in patients with giant GH-secreting pituitary adenoma is complex and multimodal therapy is necessary.

Severe Hallux Valgus

Introduction: Hallux valgus is a multifactorial disease, and heredity is the main associated factor. Pain and discomfort when using closed-toed shoes occur in many cases, adversely affecting quality of life. Surgical treatment is indicated when pain and disability persist after conservative treatment. Currently, more than 150 surgical techniques are described for hallux valgus correction, with no consensus regarding the best treatment. With the advent of minimally invasive techniques for hallux valgus correction, Vernois developed the percutaneous chevron osteotomy. This technique allows up to 100% lateral translation of the contact area of the osteotomy. Objective: the objective of the present study was to assess the correction of radiographic parameters, clinical improvement and potential complications of the first 30 cases of moderate and severe hallux valgus operated on at our hospital using the percutaneous chevron technique. Methods: A total of 26 patients (30 feet) underwent surgery. The following parameters were measured in the pre- and postoperative periods: the first metatarsophalangeal (MTP) angle, the intermetatarsal angle between the 1st and 2nd metatarsals (IMA), the distal metatarsal articular angle (DMAA) and the pre- and postoperative American Orthopedic Foot and Ankle Society (AOFAS) scores, with a minimum follow-up period of 6 months. Results: The mean age of the patients was 52.3 years. During the preoperative period, the mean AOFAS score was 45.6; it increased to 90.3 after the procedure, indicating a statistically significant improvement. The mean MTP angle, IMA and DMAA were 29.7°, 14.2° and 14.2° before surgery and 12.8°, 8.2° and 11.1° after surgery, respectively. The improvements in the MTP angle and the IMA were also significant. There was no decrease in angles or worsening of AOFAS scores during follow-up. Conclusion: The percutaneous chevron technique was safe and effective for correcting cases of moderate and severe hallux valgus, with significant improvements in clinical and radiological parameters and a low rate of postoperative complications.

Purpose:To describe the initial experience of laparoscopic hand-assisted Miami pouch in a group of patients undergoing pelvic exenterations for pelvic malignancies.Materials and Methods:Thirteen female patients underwent laparoscopic-assisted pelvic exenteration in our center between September 2000 and November 2007. Six of them had the Miami pouch created for urinary diversion. The continent diversion was created extracorporeally through a right iliac fossa minilaparotomy.Results:The mean total operative time for the laparoscopic-assisted exenteration and reconstruction was 382 minutes (range, 270-480 minutes), but specifically for the Miami pouch, it took a mean time of 106 minutes (range, 90-130 minutes). Four patients (66.7%) had postoperative urinary tract infection that resolved with antibiotics. One patient had a ureteral stenosis requiring stenting and one had a Miami pouch cutaneous fistula that required a fistulectomy. The mean follow-up was 23 months (range, 9-48 months). All patients were continent and were able to self-catheterize approximately 3 to 6 times/d.Conclusions:It is technically feasible to incorporate the creation of the Miami continent urinary pouch through a minilaparotomy during laparoscopic pelvic exenteration without compromising the benefits of laparoscopic surgery.

CONTEXT: Non-derivative surgical techniques are the treatment of choice for the control of upper digestive tract hemorrhages after schistosomotic portal hypertension. However, recurrent hemorrhaging due to gastroesophagic varices is frequent. OBJECTIVE: To evaluate the outcome of treatment based on embolization of the left gastric vein to control the reoccurrence of hemorrhages caused by gastroesophagic varices in patients with schistosomiasis previously submitted to non-derivative surgery. METHODS: Rates of reoccurrence of hemorrhages and the qualitative and quantitative reduction of gastroesophagic varices in patients undergoing transhepatic embolization of the left gastric vein between December 1999 and January 2009 were studied based on medical charts and follow-up reports. RESULTS: Seven patients with a mean age of 39.3 years underwent percutaneous transhepatic embolization of the left gastric vein. The mean time between azigoportal disconnections employed in combination with splenectomy and the percutaneous approach was 8.4 ± 7.3 years, and the number of episodes of digestive hemorrhaging ranged from 1 to 7 years. No episodes of reoccurrence of hemorrhaging were found during a follow-up period which ranged from 6 months to 7 years. Endoscopic postembolization studies revealed reductions in gastroesophagic varices in all patients compared to preembolization endoscopy. CONCLUSIONS: Percutaneous transhepatic embolization of the left gastric vein in patients with schistosomiasis previously submitted to surgery resulted in a decrease in gastroesophagic varices and was shown to be effective in controlling hemorrhage reoccurrence.

Extramedullary hematopoiesis is a rare condition characterized by the formation of blood cells outside the bone marrow. It is commonly seen in patients with hematopoietic disorders or chronic anemia. Here, we report the case of a 55-year-old patient who had extramedullary hematopoiesis that manifested as an asymptomatic posterior mediastinal mass. Chest computed tomography showed a 30 × 35-mm mass located on the left side of the D11 vertebra. Laboratory investigations revealed no signs of anemia. The tumor was safely and completely removed using video-assisted thoracoscopic surgery. Pathological studies confirmed the extramedullary hematopoiesis nature of the tumor.
