Incidence of radiographic and clinically significant pneumothorax or hemothorax after thoracic discectomy via mini-open lateral retropleural approach without prophylactic chest tube placement.

OBJECTIVE: The mini-open lateral retropleural (MO-LRP) approach is an effective option for surgically treating thoracic disc herniations, but the approach raises concerns for pneumothorax (PTX). However, chest tube placement causes insertion site tenderness, necessitates consultation services, increases radiation exposure (requires multiple radiographs), delays the progression of care, and increases narcotic requirements. This study examined the incidence of radiographic and clinically significant PTX and hemothorax (HTX) after the MO-LRP approach, without the placement of a prophylactic chest tube, for thoracic disc herniation. METHODS: This study was a single-institution retrospective evaluation of consecutive cases from 2017 to 2022. Electronic medical records were reviewed, including postoperative chest radiographs, radiology and operative reports, and postoperative notes. The presence of PTX or HTX was determined on chest radiographs obtained in all patients immediately after surgery, with interval radiographs if either was present. The size was categorized as large (≥ 3 cm) or small (< 3 cm) based on guidelines of the American College of Chest Physicians. PTX or HTX was considered clinically significant if it required intervention. RESULTS: Thirty patients underwent thoracic discectomy via the MO-LRP approach. All patients were included. Twenty patients were men (67%), and 10 (33%) were women. The patients ranged in age from 25 to 74 years. The most commonly treated level was T11-12 (n = 11, 37%). Intraoperative violation of parietal pleura occurred in 5 patients (17%). No patient had prophylactic chest tube placement. Fifteen patients (50%) had PTX on postoperative chest radiographs; 2 patients had large PTXs, and 13 had small PTXs. Both patients with large PTXs had expansion on repeat radiographs and were treated with chest tube insertion. Of the 13 patients with a small PTX, 1 required 100% oxygen using a nonrebreather mask; the remainder were asymptomatic. One patient, who had no abnormal findings on the immediate postoperative chest radiograph, developed an incidental HTX on postoperative day 6 and was treated with chest tube insertion. Thus, 3 patients (10%) required a chest tube: 2 for expanding PTX and 1 for delayed HTX. CONCLUSIONS: Most patients who undergo thoracic discectomy via the MO-LRP approach do not develop clinically significant PTX or HTX. PTX and HTX in this patient population should be treated with a chest tube only when there are postoperative clinical and radiographic indications.

Cerebral Myiasis, An Unexpected Intraoperative Finding - A Case Report and Systematic Review.

Postoperative complications, exemplified by surgical site infections, are commonplace in the realm of daily surgical interventions. Conversely, certain infectious entities, such as cerebral myiasis (CM), are distinctly rare. This report elucidates the clinical presentation of a 74-year-old female afflicted with a CSF fistula, within the context of a preceding surgical microvascular decompression employing a suboccipital craniotomy approach. Notably, the course of evaluation and treatment unveiled an intraoperative manifestation of severe CM. This case report underscores the critical significance of prompt identification, precise diagnostic elucidation, and comprehensive multidisciplinary management to optimize patient outcomes in instances of CM. Furthermore, a systematic literature review on CM supplements this report, contributing to the understanding of this infrequent complication.
