Single-stage resection of multiple pulmonary ground-glass opacities: A clinical analysis / 中国胸心血管外科临床杂志

@#Objective    To summarize our experience of surgical resection of multiple ground-glass opacity (GGO) in recent years. Methods    Clinical data of patients who underwent one-stage resections of multiple GGO from November 2015 to May 2019 in our hospital were collected, including 13 males and 52 females at an average age of 56.0±9.4 years. The clinical effects and pathological types of GGO were evaluated. Results    Time interval from first discovery to surgery was 8-1 447 (236.5±362.4) days. There were 48 patients with unilateral surgery and 17 patients with bilateral surgery during the same period. Except for 2 patients who underwent open thoracotomy due to total thoracic adhesions, other patients underwent video-assisted thoracoscopic surgery (VATS). The mean postoperative hospital stay was 12.2±4.3 days. No severe perioperative complication or death occurred. A total of 156 GGO lesions were resected, 80 lesions were pure GGO, including 58 (72.5%) malignant lesions and 22 (27.5%) benign lesions, with an average diameter of 7.7±3.3 mm and 5.5±2.6 mm, respectively. Another 76 lesions were mixed GGO, including 69 (90.8%) malignant lesions and 7 (9.2%) benign lesions, with an average diameter of 13.6±6.6 mm and 7.7±3.5 mm, respectively. Conclusion    Patients with multiple GGO should be treated with anti-inflammatory therapy firstly. When conservative treatment is ineffective and no benign outcomes are observed, surgical treatment should be considered. And when lung function is sufficient for patients to underwent surgeries, the simultaneous unilateral or bilateral thoracoscopic resection is suggested, and the sublobar resection or lobectomy methods can be adopted flexibly according to the clinical features of the lesion and the rapid pathological results, which will not increase the risk of postoperative complications. Otherwise, surgical resection should be given priority for pure GGO lesions with a diameter > 7.7 mm and mixed GGO lesions.

Single Stage Transanal Endorectal Pull-through Operation for Hirschsprung’s Disease in Neonate: A Single Center Experience / 소아외과

PURPOSE: The single stage transanal pull-through (SSPT) for Hirschsprung’s disease is becoming the most popular procedure. This single center study compared the result of single stage operation with two-stage operation for Hirschsprung’s disease in neonates. METHODS: We retrospectively reviewed medical records of all patients who were diagnosed as Hirschsprung’s disease and underwent SSPT or two-stage operation operation in Asan Medical Center between January 2003 and July 2014. RESULTS: There were 17 SSPT and 28 two-stage operation. The mean age of SSPT group was 14.2±7.1 days, and the mean age of two-stage operation group was 15.4±8.6 days for stomy formation, and 188.6±36.3 days for Duhamel operation. The operation time of SSPT was shorter than Duhamel operation (145.0±37.0 minutes vs. 193.0±36.0 minutes, p<0.001). The mean follow-up period of SSPT and two-stage operation was 35.5±34.9 months (range, 2-132 months) and 56.6±35.5 months (range, 1-121 months), respectively. Defecation problem rate such as fecal soiling or fecal impaction showed no significant difference between the two groups (p=0.719). Two SSPT patients required botulinum toxin injection due to rectal stenosis. Three patients of SSPT group underwent re-do endorectal pull-through due to remnant aganglionic or hypoganglionic bowel. CONCLUSION: The SSPT showed shorter hospital days. However, few patients experienced rectal stenosis, but were manageable with botulinum toxin injection. The SSPT requires experienced-pathologist, as well as surgeon, because intra-operation pathology reading is critical for appropriate SSPT. SSPT is a feasible and reasonable option to treat Hirschsprung’s disease.

Single-Stage Removal of Thoracic Dumbbell Tumors from a Posterior Approach Only with Costotransversectomy

PURPOSE: Thoracic dumbbell tumors are relatively rare, usually arising from neurogenic elements. Methods for surgical removal thereof remain controversial. The purpose of this study was to evaluate the surgical results of a single-stage posterior approach with laminectomy and costotransversectomy only for the management of thoracic dumbbell tumors. MATERIALS AND METHODS: Eight cases of thoracic large dumbbell tumor were analyzed retrospectively: seven men and one woman (mean age, 49 years). Pathologic findings included schwannoma in five patients, neurofibroma in two patients (Recklinghausen in one patient), and ganglioneuroma in one patient. All patients underwent single-stage removal of dumbbell tumors by a posterior approach followed by laminectomy and costotransversectomy combined with instrumentation. Clinical and radiologic outcomes were reviewed, thereafter. RESULTS: Operative time ranged from 185 to 420 minutes (mean, 313 minutes), with estimated blood loss ranging from 71 to 1830 mL (mean, 658 mL). Postoperative complications included atelectasis in one case. All patients had tumors successfully removed with no neurological deterioration. Spinal deformities were not observed in any patients at the last follow-up (mean, 52 months), with instrumentation. CONCLUSION: Single-stage surgery with laminectomy and costotransversectomy may be useful for removing thoracic dumbbell tumors without a combined anterior approach.

Four Cases of Single-Stage Surgery of Abdominal Aortic Aneurysm with MIDCAB on Revascularization / 日本心臓血管外科学会雑誌

Many patients with abdominal aortic aneurysm have coexisting coronary artery disease. There is no evidence regarding the safety or efficacy of surgery, or whether surgery should be done in 1 session or in more than 1 session. Single-stage surgery is generally more invasive. We performed single-stage surgery using minimally invasive direct coronary artery bypass graft surgery (MIDCAB) for revascularization in 4 patients with abdominal aortic aneurysm and coronary artery disease. The average operation time was 399 min. The average number of bypassed grafts was 1.75 per patient. All patients were extubated within 24 h after surgery. The average discharge time was 29.3 postoperative days. No patients died during surgery or during hospitalization. Multidetector-row CT scan showed all bypassed grafts to be patent. MIDCAB surgery is safe and effective for revascularization in performing single-stage surgery in patients with abdominal aortic aneurysm and coronary artery disease.
