Scott JE, Auzenne DA, Massari F, Singh A, Donovan V, Mayhew PD, Case B, Scharf VF, Buote N, Wallace ML. Complications and outcomes of thoracoscopic-assisted lung lobectomy in dogs. Vet Surg 2023; 52:106-115. [PMID: 36168280 DOI: 10.1111/vsu.13886] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2021] [Revised: 07/10/2022] [Accepted: 08/09/2022] [Indexed: 12/31/2022]
Abstract
OBJECTIVE To describe complications and outcomes of dogs undergoing thoracoscopic-assisted (TA) lung lobectomy. STUDY DESIGN Multi-institutional, retrospective study. ANIMALS Client-owned dogs (n = 30). METHODS Medical records of dogs that underwent TA lung lobectomy were reviewed. Signalment, bodyweight, clinical signs, imaging findings, surgical variables, complications, and short-term/long-term outcome were assessed. Thoracoscopic-assisted lung lobectomy was performed with a mini-thoracotomy. RESULTS Twelve intraoperative complications were recorded in 11 dogs, 6 requiring conversion to open thoracotomy. Reasons for conversion were reported in 5/6 dogs and included adhesions (2), difficultly manipulating the lesion through the mini-thoracotomy (2), and acute oxygen desaturation (1). One lung ventilation was successful in 4 of the 7 dogs in which this was attempted. A linear stapling device (DST series Medtronic, Minneapolis, Minnesota) was used for lung lobe ligation in 14 dogs. Twenty-three dogs underwent surgery for a neoplastic lesion, with 19 of these being carcinoma. The median lesion size was 4.3 cm (range 1-10 cm); margins were clean, except in 1 dog. Complications were documented in 8 dogs prior to discharge, 5 of these being classified as mild. Twenty-nine dogs were discharged at a median of 47 h postoperatively (range 24-120 h). Death was reported in 9 dogs, with a median survival time of 168 days (range 70-868 days). CONCLUSION Thoracoscopic-assisted lung lobectomy was achieved with few major complications in the population reported here. Dogs were able to be discharged from hospital quickly, with most surviving beyond the follow-up period. CLINICAL SIGNIFICANCE Thoracoscopic-assisted lung lobectomy may be considered to facilitate the excision of larger pulmonary lesions or to treat smaller dogs, in which a thoracoscopic excision may be technically more challenging.

Abstract
OBJECTIVES To compare the perioperative and oncologic outcomes following pneumonectomy performed by uniportal video-assisted thoracoscopic surgery (U-VATS) and thoracotomy in patients with centrally located non-small cell lung cancer (NSCLC). MATERIALS AND METHODS Patients with NSCLC who underwent pneumonectomy at the Shanghai Pulmonary Hospital (SPH) and Sun Yat-sen University Cancer Center (SYUCC) with the U-VATS approach or open approach between 2011 and 2016 were selected. Propensity score matching (1:3) was performed to balance the baseline covariates. Overall survival (OS) rates and recurrence-free survival (RFS) rates were estimated and compared using the Kaplan-Meier method, respectively. RESULTS The enrollees in the study were 579 patients in the SPH cohort, with 501 (86.5%) in the open group and 48 (13.5%) in the U-VATS group, and 271 patients in the SYUCC cohort, with 245 (90.4%) in the open group and 26 (9.6%) in the U-VATS group. After propensity score matching, morbidity rates and 30-day mortality rates were found to be similar between the U-VATS group and open group in both the SPH and SYUCC cohorts. The long-term OS rate of patients who underwent U-VATS pneumonectomy did not significantly differ compared with the patients who underwent open pneumonectomy in both cohorts (SPH, p = .900; SYUCC, p = .240). Cox regression analysis revealed that the surgical option was not a risk factor for the OS rate (SPH: hazard ratio [HR], 0.925; 95% confidence interval [CI], 0.555 to 1.542; SYUCC: HR, 1.524; 95% CI, 0.752 to 3.087). CONCLUSION U-VATS can be used to safely perform pneumonectomy in patients with centrally located NSCLC without compromising the perioperative and oncologic outcomes compared with an open approach.

Abstract
Case summary A 2-year-old female neutered domestic shorthair cat was presented for
investigation of acute onset tachypnoea and dyspnoea. Pyothorax was
diagnosed based on thoracic radiographs and fluid analysis. Medical
treatment consisted of bilateral thoracostomy tube placement, antibiotic
therapy and thoracic lavage. After 12 days of medical management infection
was still present, warranting exploratory thoracotomy. At surgery,
encapsulated abscesses were found in the left lung, right cranial and right
middle lobes. The right caudal lobe was the only macroscopically
non-abscessated lobe, and appeared to have a parenchymal laceration 8 mm
long over the dorsolateral surface. Following partial pericardiectomy,
mediastinectomy and debridement of abscesses, a pericardial flap was
reflected caudolaterally and apposed over the laceration to seal the
affected lung lobe. This flap was sutured to a rim of fibrinous adhesion
that was partially covering this lobe. After 8 days the cat was discharged
with antibiotic therapy for 3 more weeks. Follow-up assessment at 19 and 38
weeks postoperatively confirmed the cat to have good exercise tolerance.
Thoracic radiographs at 19 weeks revealed good bilateral aeration of the
pulmonary parenchyma without pleural effusion. Relevance and novel information Lung lobe laceration can be treated by lung lobectomy or direct suturing of
the lung parenchyma. This is the first report using a pericardial flap to
repair a lung laceration. Pericardial flap was successfully used to treat
this lung laceration where lobectomy was contraindicated. Encouraging
results were present at 8 months postoperatively.

Abstract
Pneumonectomy is the resection of all lung lobes from one side of the thorax. The clinical findings, treatment and outcome of four cases of feline chronic pyothorax managed with exploratory thoracotomy and pneumonectomy are reported. All cases were initially medically managed with thoracic drain placement and antibiosis. However, resolution was not achieved with medical therapy and diagnostic imaging findings consistent with an area of abscessation or marked lung lobe consolidation were identified, supporting a decision for surgical management. Surgical exploration was performed via median sternotomy and, on the basis of gross inspection, non-functional lung was removed. A left-sided pneumonectomy was performed in three cats and a right-sided pneumonectomy in one. All cases survived to discharge and an excellent quality of life was reported on long-term follow-up. Pneumonectomy appears to be well tolerated in the cat.

Abstract
OBJECTIVE To report the signalment, presenting clinical signs, surgical complications, histologic diagnosis, postoperative complications, and outcome of dogs and cats undergoing pneumonectomy. STUDY DESIGN Retrospective case series; multicenter study. ANIMALS Client-owned dogs (n=17) and cats (n=10). METHODS Signalment, clinical signs, side affected, surgical data, preoperative diagnostic tests (including complete blood count, serum biochemistry, cytologic diagnosis, chest radiographs, and computed tomography), histologic diagnosis, surgical complications, adjunctive therapy, and date and cause of death were collected from records of dogs and cats that underwent pneumonectomy. Survival estimates and complication were assessed. RESULTS Seventeen animals had a left-sided pneumonectomy performed (12 dogs, 5 cats) and 10 animals had a right-sided pneumonectomy (5 dogs, 5 cats). Fourteen animals were diagnosed with neoplasia (52%). The overall incidence of complications for dogs and cats were 76 and 80%, respectively, with major complications in 41 and 50%, respectively. Respiratory complications (persistent pleural effusion, oxygen dependence, persistent increased respiratory rate, or coughing) were the most frequent complications. No animals died or were euthanatized intraoperative or within the first 24 hours postoperative. One dog (6%) and 2 cats (20%) died, or were euthanatized in the first 2 weeks postoperative. CONCLUSION Based on this case series, right and left pneumonectomy can be performed with low perioperative mortality in dogs and cats, with some animals experiencing prolonged survival.

Abstract
OBJECTIVE To describe indications for, and outcomes after, pneumonectomy in dogs and cats, including assessment of immediate postoperative respiratory function in comparison to dogs undergoing single lung lobectomy. STUDY DESIGN Retrospective case series. ANIMALS Dogs (n=16) and cats (n=7) with naturally occurring pulmonary disease. METHODS Medical records (1990-2014) of dogs and cats undergoing right or left pneumonectomy were reviewed. Data retrieved included signalment, history, preoperative diagnostics, operative descriptions, postoperative data including respiratory function, and postdischarge outcomes. For respiratory function comparisons, medical records of dogs having undergone a single lung lobectomy via median sternotomy (n=15) or intercostal thoracotomy (n=15) were reviewed. RESULTS Twenty-three cases (16 dogs, 7 cats) were included. Pneumonectomy was performed for congenital (1 dog, 1 cat), neoplastic (8 dogs, 1 cat), and infectious (7 dogs, 5 cats) disease. Postoperative aspiration pneumonia occurred in 2 dogs; 15 of 16 dogs (94%) and 6/7 cats (86%) survived to hospital discharge. After pneumonectomy, dogs had a significantly higher postoperative PaO2 on 21% oxygen (P=.033) and lower postoperative A-a gradient (P=.004) compared to dogs undergoing single lung lobectomy. Survival times (right-censored at last follow-up) for dogs ranged from 2 days to 7 years (estimated median=1,868 days) and for cats from 1-585 days. CONCLUSION Dogs and cats have acceptable respiratory function immediately postoperatively and most have protracted long-term survival after pneumonectomy for a variety of pulmonary diseases.

Abstract
Although left- or right-sided pneumonectomy is tolerated by normal dogs, complications impacting the respiratory, cardiovascular, and gastrointestinal systems are not uncommon. Pneumonectomy in dogs results in secondary changes in the remaining lung, which include: decreased compliance and vital capacity; and increased pulmonary vascular resistance potentially leading to right ventricular hypertrophy. Such alterations make the anesthetic management of an animal with one lung particularly challenging. This report describes a dog with a history of left pneumonectomy due to Aspergillus fumigatus pneumonia 3 yr before presentation. The dog presented with a vaginal wall prolapse, and surgical resection of the protruding vaginal wall, ovariectomy, and prophylactic gastropexy were performed. Anesthesia was induced with midazolam, fentanyl, and propofol and was maintained with isoflurane using intermittent positive pressure ventilation and a constant rate infusion of fentanyl. Epidural anesthesia was also used. Recovery and postoperative management were uncomplicated. Intensive hemodynamic and respiratory monitoring and appropriate response and treatment of any detected abnormalities, taking into consideration the pathophysiologic alterations occurring in a pneumonectomized animal, are required for successful perianesthetic management.

Abstract
This study aimed to assess the influence of lobectomy and pneumonectomy on cardiac rhythm and on the dimensions and function of the right-side of the heart. Twelve dogs undergoing lobectomy and eight dogs undergoing pneumonectomy were evaluated preoperatively and one month postoperatively with electrocardiography and Doppler echocardiography at rest. Pulmonary artery systolic pressure (PASP) was estimated by the tricuspid regurgitation jet (TRJ) via the pulse wave Doppler velocity method. Systemic inflammatory response syndrome criteria (SIRS) were also evaluated based on the clinical and hematological findings in response to lobectomy and pneumonectomy. Following lobectomy and pneumonectomy, we predominantly detected atrial fibrillation and varying degrees of atrioventricular block (AVB). Dogs that died within seven days of the lobectomy (n = 2) or pneumonectomy (n = 1) had complete AVB. Preoperative right atrial, right ventricular, and pulmonary artery dimensions increased gradually during the 30 days (p<0.05) following pneumonectomy, but did not undergo significant changes during that same period after lobectomy. Mean PASP was 56.0 ± 4.5 mmHg in dogs having significant TRJ after pneumonectomy. Pneumonectomy, but not lobectomy, could lead to increases (p<0.01) in the SIRS score within the first day post-surgery. In brief, it is important to conduct pre- and postoperative cardiac evaluation of dogs undergoing lung resections because cardiac problems are a common postoperative complication after such surgeries. In particular, complete AVB should be considered a life-threatening complication after pneumonectomy and lobectomy. In addition, pneumonectomy appears to increase the likelihood of pulmonary hypertension development in dogs.

Abstract
O propósito das ressecções pulmonares em cães e gatos, quer sejam por lobectomia ou pneumonectomia, é a cura ou paliação de processos broncopulmonares sempre que os meios conservadores de tratamento clínico sejam considerados ineficientes. Tendo em vista as significativas alterações resultantes da pneumonectomia, novos estudos experimentais devem ser feitos para avaliar as vantagens dessa intervenção cirúrgica e determinar a maneira como aplicá-la com segurança. O presente estudo tem como objetivo avaliar as alterações eletrocardiográficas em dez cães adultos de ambos os sexos, sem raça definida, com 10-30 kg, submetidos à pneumonectomia direita. Foram avaliados diariamente os parâmetros clínicos de cada cão e as alterações em todas as derivações do eletrocardiograma. Todos os cães apresentaram um bom desenlace pós-operatório. Apenas um cão apresentou alteração de relevância clínica, um caso de complexos ventriculares prematuros, possivelmente decorrente da parada cardiorrespiratória, que foi revertido com sucesso. Houve diminuição da amplitude dos complexos QRS nos primeiros 14 dias, retornado ao normal após 60 dias de pós-operatório.

Abstract
The comparison of the histologic healing and bronchopleural fistula (BPF) complications encountered with three different BS closure techniques (manual suture, stapler and manual suture plus tissue flab) after pneumonectomy in dogs was investigated for a one-month period. The dogs were separated into two groups: group I (GI) (n = 9) and group II (GII) (n = 9). Right and left pneumonectomies were performed on the animals in GI and GII, respectively. Each group was further divided into three subgroups according to BS closure technique: subgroup I (SGI) (n = 3), manual suture; subgroup II (SGII) (n = 3), stapler; and subgroup III (SGIII) (n = 3), manual suture plus tissue flab. The dogs were sacrificed after one month of observation, and the bronchial stumps were removed for histological examination. The complications observed during a one-month period following pneumonectomy in nine dogs (n = 9) were: BPF (n = 5), peri-operative cardiac arrest (n = 1), post-operative respiratory arrest (n = 1), post-operative cardiac failure (n = 1) and cardio-pulmonary failure (n = 1). Histological healing was classified as complete or incomplete healing. Histological healing and BPF complications in the subgroups were analyzed statistically. There was no significant difference in histological healing between SGI and SGIII (p = 1.00; p > 0.05), nor between SGII and SGIII (p = 1.00; p > 0.05). Similarly, no significant difference was observed between the subgroups in terms of BPF (p = 0.945; p > 0.05). The results of the statistical analysis indicated that manual suture, stapler or manual suture plus tissue flab could be alternative methods for BS closure following pneumonectomy in dogs.
