P-OGC91 Significance of the number, size and type of drains used for intercostal drainage after oesophagectomy for cancer

Background Pleural space drainage with intercostal drains (ICD) is performed after oesophagectomy to allow the lung to reinflate, remove excess fluid post-operatively, and signal chyle or enteric content. Enhanced recovery protocols encourage the use of the minimum number of drains for the shortest duration to facilitate rapid recovery after surgery. There is wide variability in the type, number and size of drains inserted at operation. This study sought to identify the most effective drain pattern insertion, using the need for respiratory reintervention as the primary end point and secondary outcome of the presence of pleural effusions. Methods All patients undergoing oesophagectomy for cancer in one unit were included between November 2014 and December 2020. The operation performed, drain sizes, sides and type were recorded. Respiratory reintervention was defined as replacement of an ICD, bronchoscopy, pleural aspiration or reintubation. The primary and secondary end points, and potential confounders such as age, histology, pre-operative stage of disease, neoadjuvant therapy, pre-existing lung disease, and anastomotic or chyle leak were recorded. Results The study period encompassed 258 patients who underwent oesophagectomy for cancer. Median age 69 (range 32-82), 211 male, 226 ACA:32 SCC, 224 neoadjuvant therapy, 212 right-sided thoracic operations, 46 left thoracoabdominal approach. Post-operative respiratory reinterventions occurred in 47 patients (18.2%). At least one post-operative pleural effusion was present in 52 patients (20.2%): 9 bilateral; 26 contralateral; 17 ipsilateral to the side of thoracic surgery. 67% of effusions were contralateral to the operated side. The use of two or three ICDs (HR 371683269, p < 1), one or two operative side ICDs (HR 0, p < 1), Blake’s drains in place of rigid ICDs (HR 0.938 [0.422-2.085], p < 0.875), and size 24F compared to 28F drains (HR 0, p < 0.999) are not significantly associated with post-operative respiratory reinterventions. Similarly, the presence of post-operative pleural effusions is not significantly associated with the use of two or three ICDs (HR 240242843, p < 1), one or two operative side ICDs (HR 0, p < 1), Blake’s drains in place of rigid ICDs (HR 1.505 [0.665-3.405], p < 0.327), and size 24F compared to 28F drains (HR 1.055 [0.109-10.2], p < 0.963). Conclusions This study supports the use of contralateral pleural space drainage as two thirds of effusions were contralateral to the operated side. It shows no correlation between the size of drains, number of drains or use of Blakes drains and the likelihood of requiring a post-operative respiratory intervention or development of post-operative pleural effusion. Therefore the ERAS principles of the fewest number of drains for the shortest duration should be adopted.

Giant posterior mediastinal schwannoma requiring a thoracoabdominal approach for excision: Case report and literature review

Background: A schwannoma is a tumor of the peripheral nerve sheath. They are the most common benign tumor; presenting at any age, and at any site of the body and also one of the most common posterior mediastinal tumors. Posterior mediastinal schwannoma is usually identified incidentally in chest radiographs and with follow-up imaging such as CT scan. Large posterior mediastinal schwannoma usually presents with local symptoms. To confirm diagnosis and obtain local control, surgical excision is the usual approach. Case Description: Here, we present a case of a 56-year-old female who presented with chronic low back pain. The lesion was picked up on an ultrasound scan to look at her kidneys. She was not experiencing any neurological symptoms. Excision of the tumor was made through a right thoracoabdominal approach. A WHO Grade 1 tumor was diagnosed on histology. There were no signs of recurrence in the follow-up scans. Conclusion: Giant posterior mediastinal schwanommas are very rare with only one other reported case requiring a thoracoabdominal approach for excision. Though giant schwanommas raise concern for malignancy due to their large size, they generally turn out to be benign

Ten-year Review of Patients with Resected Esophagogastric Junction Adenocarcinoma in the Philippine General Hospital

Objective. To describe the clinicopathologic profile, management, and outcomes of patients with esophagogastric junction (EGJ) adenocarcinoma in the local setting. Methods. Data was obtained from patients who had curative surgery for EGJ adenocarcinoma from 2004–2013 in the Philippine General Hospital. We used student's T-tests, analysis of variance, chi-squared and Fisher’s exact tests for comparisons and Cohen’s kappa index for correlation. A P value of less than or equal to 0.05 was considered significant. Results. We included 88 patients (81.2% male) with mean age of 55.2 years. Eight percent were clinical Siewert type I; 23.9% were type II; 15.9% were type III; and majority (52.3%) were unknown type. Surgical approach and resection differed across the Siewert types (P<0.000). Thoracoabdominal approach (72.7%) and distal esophagectomy with total gastrectomy (77.3%) were the most common procedures. Many had at least pathologic T3 (80.6%), N2 (54.5%), and stage III (68.2%) disease. Neoadjuvant and adjuvant chemotherapy was given in 1.2% (1/82) and 48.6% (18/37), respectively. In-hospital morbidity was 40%; mortality was 4.5%; 1-year disease-free survival rate was 69.4%; and overall survival rate was 76.5%. Correlation was fair between preoperative and pathologic Siewert type (P=0.003) and poor between clinical and pathologic stage (P=0.115). Patients with recurrence had higher pathologic lymph nodes (P=0.029) and more advanced stage (P=0.022). Conclusion. EGJ adenocarcinomas were locally advanced and had poor outcomes. Surgery should be individualized and multimodality approach considered.

A Prospective Study of Posterior (Transpedicular) Approach versus Anterior (Transthoracic/Thoracoabdominal) Approach for Posttraumatic Compression Fracture of Thoracolumbar Vertebra in a Tertiary Care Center: Comparison of Clinical and Radiological Outcomes

Objective The aim of this article was to analyze the clinical and radiological outcomes of transpedicular decompression (posterior approach) and anterolateral approach in patients with traumatic thoracolumbar spinal injuries. Methods It was a prospective study of patients with fractures of dorsolumbar spine from December 2011 to December 2013. A total of 60 patients with traumatic spinal injuries were admitted during the study period (December 2011–2013), of which 51 cases were finally selected and taken for operations while 3 were eventually lost in follow-up. Twenty patients were operated by anterolateral approach, titanium mesh cage, and fixation with bicortical screws. Twenty-eight patients were treated with posterior approach and transpedicular screw fixation. Clinical and radiographic evaluations were performed on all 48 patients before and after surgery. Results There were 48 patients of thoracolumbar burst fractures with 40 male and 8 female patients. Range of follow-up was from 1 month to 20 months, with a mean of 7.4. Preoperatively in anterior group, 65% of the patients were bed ridden, 20% patients were able to walk with support, and 15% of the patients were able to walk without support. In posterior group, 78.57% patients were bed ridden, 10.71% were able to walk with support, and 10.71% patients were able to walk without support. Kyphotic angle changes were seen in 16 patients out of 18 in anterior group and 20 patients in posterior group out of 25. Out of 18 patients in anterior group, 14 showed reduction in kyphotic angle of 10 to 100 (improvement), with mean improvement of 4.070. In posterior group, 7 patients showed improvement of 10 to 80 (reduction in kyphotic angle) whereas 13 patients showed deterioration of 1 to 120. The mean improvement was 2.140 in 7 patients and mean deterioration was 4.920. No statistical difference was found (p > 0.05) regarding improvement in urinary incontinence during the follow-up period. Conclusion There are significant differences in anterior and posterior approaches in terms of clinical improvement. Compared with posterior approach, the anterolateral approach can reduce fusion segment and well maintain the kyphosis correction. The selection of treatment should be based on clinical and radiological findings, including neurological deficit.

Laparoscopic-assisted left thoracoabdominal esophagectomy (LLTA): an innovative approach for locally advanced tumors of the gastroesophageal junction

ABSTRACT Purpose To report a novel approach for locally advanced tumors located at the gastroesophageal junction (GEJ) using a laparoscopic abdominal phase and open left thoracotomy with the patient in a single right lateral decubitus position. Background The standard open left thoracoabdominal approach offers excellent exposure and access to the GEJ and lower esophagus. It also involves a single position for the procedure, shortening the operation time. The disadvantages are a large incision, division of the costochondral junction, and a low-level thoracotomy. The laparoscopic-assisted left thoracoabdominal esophagectomy (LLTA) is performed with the patient in the same right lateral decubitus position, but initially rolled away from the operator at 45° allowing laparoscopic gastric mobilization and lymphadenectomy. The patient is then tilted back to the lateral position for the thoracic phase. An anterolateral left thoracotomy is performed through the higher fifth intercostal space allowing a high intrathoracic anastomosis, just below the aortic arch. No disruption of the costochondral junction is made. Methods Consecutive patients selectively treated for locally advanced GEJ tumors with an LLTA approach between 2013 and 2019 were analyzed and compared to national standards (NOGCA). Results This series of 74 consecutive patients had a mean age of 63 years. The median operation time was 235 minutes. The median inpatient stay was 10 days (NOGCA 9 [11–17]). The tumors were predominantly adenocarcinoma (95%) and located at the GEJ (92%). The majority were locally advanced T3 or T4 tumors. Postoperative morbidity was low, Clavien–Dindo (C–D) 0 in 52.7% patients, C–D1 (1.4%), C–D2 (31.1%), C–D3a (5.4%), C–D4a (9.5%), and C–D5 (1.4%). The median number of total lymph nodes (LN) excised was 28 (NOGCA &gt;15); LN % yield ≥18 was 90% (NOGCA 82.5%). Positive nodes were located at the lesser-curve (40%), paraesophageal (32.4%), and subcarinal regions (2.7%). Positive circumferential resection margins (&lt;1 mm) were present in 28.4% of resected specimens (NOGCA 25.1%). This is reflective of the high proportion T3/T4 tumors selected for this approach. Hospital and 30-day mortality was 1.4% (NOGCA 2.7%). Recurrence after LLTA was 25.7% (local 5.4%, systemic 17.6%, mixed 2.7%) at a median of 311 days (62–1,158). Conclusion This series demonstrates a novel, safe, and reproducible approach for locally advanced cancer of the GEJ. It offers a better exposure of the hiatus than the right-sided approach and avoids division of the costochondral junction and low thoracotomy seen with the open left thoracoabdominal approach.

P95 LAPAROSCOPIC ASSISTED LEFT THORACOABDOMINAL OESOPHAGECTOMY (LLTA); AN INNOVATIVE APPROACH FOR TUMOURS OF THE GASTRO-OESOPHAGEAL JUNCTION

Aim To report a novel approach for tumours located at the gastro-oesophageal junction (GOJ) using a laparoscopic abdominal phase combined with a left thoracoabdominal approach. Background and Methods The standard left thoracoabdominal approach offers excellent exposure and access to GOJ and lower oesophagus. It also involves a single position for the procedure, shortening the operation time. The disadvantages are a large incision, dividing the costochondral junction, and a low level thoracotomy. Laparoscopic Left Thoracoabdominal Oesophagectomy (LLTA) is performed with the patient in the same right lateral decubitus position, but rolled away from the operator at 45xxx. allowing laparoscopic gastric mobilisation and lymphadenectomy. The thoracic phase uses an anterolateral left thoracotomy through the higher 5th intercostal space, giving a higher intrathoracic anastomosis, just below the aortic arch. No disruption of the costochondral junction is made. Consecutive patients treated for GOJ tumours with LLTA operated on during 2013-2019 were analysed and compared to national standards (NOGCA). Results This series of 70 consecutive patients had a mean age of 63 years. Median operation time was 235 minutes. Median inpatient hospital stay was 10 days (NOGCA 9 (11-17)). The majority were adenocarcinoma; predominantly located in the GOJ (Siewert Type1 (37.14%), Type2 (45.71%), Type3 (2.86%)); 90% of the tumours were T3 or T4. Postoperative morbidity was low (Clavien-Dindo 0 in 50% of the patients). The median number of total lymph nodes excised was 27.77 (NOGCA &gt;15). Positive nodes were predominantly located in the lesser-curve (40%), Para-oesophageal 34.29%; Sub-carinal 2.86%. Positive circumferential resection margins (&lt;1mm) were present in 28.57% of patients (NOGCA 25.1%). In-Hospital and 30 day mortality was 1.43% (NOGCA 2.7%). Recurrence after LLTA was 24.29% at a mean 371 days (local 5.7%, systemic 15.7%, mixed 2.86%). Conclusion This series demonstrates a novel, safe and reproducible left sided approach for cancer of the GOJ. There is good exposure at the hiatus, without the division of the costochondral junction and low thoracotomy.
