Modified Incisional Negative Pressure Wound Therapy Increases Seroma Evacuation: An Ex Vivo Model

Background. Incisional negative wound pressure therapy (iNPWT) is a relatively novel dressing technique with the aim of reducing postoperative wound infections and dehiscence in high-risk wounds after all kinds of surgical procedures. There is a lack of theoretical knowledge about the way those dressing would ameliorate wound healing. One aspect is the reduction of superficial tension, but significant remaining seroma might still cause deep wound infections. The aim of this study was the evaluation of technical modifications of the standard iNPWT dressing to increase seroma evacuation. Methods. iNPWT dressings were applied on the porcine abdominal wall, and an incremental pressure ramp from 50 to 200 mmHg was performed. The resulting wound pressures were measured using (i) balloon manometry and (ii) esophageal manometry catheter. Seroma evacuation was analyzed with a seroma model. All measurements were performed with (i) standard iNPWT dressing, (ii) wound gauze diverted through the incision, and (iii) placement of suction drain tube into iNPWT. Results. Due to the modifications of the iNPWT dressing, the vacuum applied by the iNPWT dressing could be transferred into the wound and was not only restricted to superficial layers. More importantly, placement of wound gauzes or suction drain tubes led to complete extraction of wound seroma. The placement of the suction drain tube showed the best combination of increased intrawound pressure as well as seroma evacuation. Conclusion. Addition of a suction drain tube to the iNPWT dressing leads to an improved function of the iNPWT dressing in our ex vivo model.

Unusual pericuff leak around proseal-laryngeal mask airway corrected by clamping gastric drain port: A case report

ProSealTM-Laryngeal Mask Airway (PLMA) (Laryngeal Mask Company, Henley-on Thames, UK) is commonly used for securing the airway with an added advantage over classic LMA as its gastric drain tube allows the insertion of Ryle’s tube and suctioning of gastric contents. The ProSeal LMA is designed in such a way that it allows controlled mechanical ventilation. During controlled mechanical ventilation, air leaks can occur because of positive airway pressures. Air leaks from the gastric drain port are almost always due to the malposition of PLMA. Here, we report a case of air leak from gastric drain port despite correctly placed PLMA and its successful management without removing the device.

Short-Term Outcome of Video Assisted Thoracoscopic Decortication in Empyema Thoracis

Background: Video-assisted thoracoscopic surgical decortication (VATS Decortication) is one of the technique for treating empyema thoracis. Objective: The purpose of the present study was to assess radiologic and functional short-term outcomes of VATS decortication in comparison with open decortication among empyema thoracis patients. Methodology: This comparative type of observational study was done at Department of Thoracic Surgery at National Institute of Diseases of Chest and Hospital (NIDCH), Dhaka, Bangladesh from July 2018 to June 2019 for a period of one year. Patients with empyema thoracis in stage II or III were included. Short-term outcomes were measured according to collection of chest drain tube in post-operative observational days (PODs), post-operative lung expansion, time taken for chest drain tube removal, postoperative hospital stay and post-operative pain (numeric rating scale) observations up to discharge from hospital. Result: A total number of 70 patients were recruited. The mean age was 36.20 ± 12.50 years. In post-operative phase apical chest drain tube collection followed by VATS procedure was found significantly lower than that of open decortication (2nd POD: p= 0.04; 3rd POD: p =0.039). Both the apical (p=0.001) and basal (p=0.039) chest drain tubes were removed earlier in patients with VATS decortication. Again, patients with VATS decortication had to stay less days in post-operative time (p=0.01). The mean post-operative pain scores was significantly higher among the patients underwent open decortication (p<0.001). Conclusion: VATS decortication has shown better outcome in terms of collection of chest drain tube in post- operative days, time taken for chest drain tube removal, post-operative hospital stay and post-operative pain in managing patients with empyema thoracis.

Tractotomy using the Penrose drain guide for deep lung injury caused by chest drainage: a case report

Background Pulmonary tractotomy effectively treats deep pulmonary penetrating injuries; however, it requires the accurate insertion of forceps or a stapler into the wound tract. This report describes a case of tractotomy using the Penrose drain guide for a deep lung injury caused by chest drainage. Case presentation A 75-year-old man suffered multiple rib fractures and hemothorax. After admission, chest tube drainage was performed because the patient’s respiratory condition deteriorated due to increased right pleural effusion. However, as the chest tube was stabbing into the right upper lobe, a pulmonary tractotomy was performed to treat the injury. Cutting the visceral pleura just over the tip of the chest tube caused the tube to completely penetrate the lung. A Penrose drain tube was fixed to the chest tube, which was then removed. The Penrose drain tube completely penetrated the lung and was coupled to the anvil side of the stapler to guide it smoothly into the wound tract. After stapling left the wound tract open, selective suture ligation of the damaged vessel and bronchioles was performed. Conclusions Although the indications for tractotomy using the Penrose drain guide are limited, we believe that this technique can be useful in patients with deep stabbing or penetrating lung injuries with rod- or tube-shaped foreign body remnants.

METHOD OF STOMA FORMATION IN PATIENTS WITH ACUTE INTESTINAL OBSTRUCTION

Surgery is the main method to treat obstructive intestinal obstruction. Stoma formation is desirable in emergency colon surgery. The aim of the study was to compare the results of the newly developed and traditional stoma formation techniques according to the number of wound purulent-inflammatory complications in the early postoperative period in patients with acute intestinal obstruction. Materials and Methods. The authors examined 62 patients with acute intestinal obstruction. The patients were divided into two groups according to the method of stoma formation. The comparison group consisted of 30 patients, who underwent traditional colostomy after obstructive resection of the sigmoid colon (rectosigmoid part of the colon). The main group included 32 patients in whom a stoma was formed using a newly developed method (patent No. 2704477). In patients of the main group, the paracolostomy space was isolated from the abdominal cavity, the preperitoneal and subgaleurotic zones of the paracolostomy space were drained. During the postoperative period local anesthetics and antibacterial drugs were administered through the drain tube. Results. Patients of the comparison group demonstrated more purulent-inflammatory complications of the median postoperative and paracolostomy wounds than those of the control group, 20.2 % (p=0.047) and 23.6 % (p=0.024), respectively. Conclusion. The proposed method of stoma formation helps to reduce wound purulent-inflammatory complications and can be used in the surgical treatment of patients with intestinal obstruction. Keywords: colon cancer, acute intestinal obstruction, postoperative complications, new method of stoma formation.

Risk Factors for Mortality and Neurodevelopmental Impairment among Neonates Born at 22–23 Weeks’ Gestation

Introduction: We aimed to evaluate the risk factors for mortality and neurodevelopmental impairment (NDI) among infants of 22–23 weeks’ gestational age, which currently remain unclear. Methods: This retrospective case-control study included 104 infants delivered at 22–23 weeks’ gestation at Kagoshima City Hospital from 2006 to 2015. We compared 65 and 34 cases of survival to discharge and postnatal in-hospital death (5 excluded), respectively, and 26 and 35 cases with and without NDI, respectively, using maternal, prenatal, and postnatal records. A high rate of survivors’ follow-up (61/65) was achieved in this study. Results: The survival rate was 75.0% (21/28) and 62.0% (44/71) among infants born at 22 and 23 weeks’ gestation, respectively. Infants who died weighed less (525.5 vs. 578 g, p = 0.04) and their intrauterine growth retardation (IUGR) rate (<5th percentile) was higher (14.7 vs. 1.5%, p = 0.02). Mortality was associated with an increased incidence of bradycardia on fetal heart rate monitoring (11.8 vs. 1.5%, p = 0.046), periventricular hemorrhagic infarction (PVHI; 32.4 vs. 6.2%, p = 0.001), necrotizing enterocolitis (NEC, surgery or drain tube; 14.7 vs. 0.0%, p = 0.004), and tension pneumothorax (29.4 vs. 6.2%, p = 0.004). There were significant differences in the proportion of PVHI (15.4 vs. 0%, p = 0.03) between infants with and without NDI. Conclusions: IUGR, bradycardia, PVHI, NEC, and tension pneumothorax were associated with neonatal mortality among infants born at 22–23 weeks’ gestation. NDI at 36–42 months’ chronological age was associated with PVHI.

Case Report: Massive Spontaneous Pneumothorax—A Rare Form of Presentation for Severe COVID-19 Pneumonia

Background and Objectives: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection is a viral disease that is spreading worldwide and became a pandemic. Although most of the time, the symptoms of the infection are flu like, a percentage of patients develop severe forms, along with severe complications. Many of them are known among front-line health workers, but the number of uncommon presentations and complications has increased. This case report aims to alert healthcare workers on less common forms of presentation, and to introduce this differential diagnosis in the evaluation of patients with COVID-19, given the increasing occurrence of pneumothorax in patients who are not mechanical ventilated. Case presentation: A 57-year-old female patient came to the Emergency Department (ED) by ambulance, with acute respiratory failure. She had SpO2 (peripheral O2 saturation ) = 43% on room air at home, and 86% on admission in ED after oxygen delivery (on a reservoir mask). SARS-CoV-2 infection was suspected based on symptoms that started three days ago (fever, dry cough, dyspnea, and fatigability). Blood was taken for lab tests, pharyngeal and nasal swabs for the reverse transcription–PCR (RT-PCR) test, and native computed tomography (CT) was scheduled. The thoracic CT scan showed massive right pneumothorax, partially collapsed lung, multiple bilateral lung infiltrates with a ground glass aspect and the RT-PCR test came back positive for SARS-CoV-2 infection. Despite the prompt diagnosis and treatment of pneumothorax (thoracostomy was performed and the drain tube was placed), the patient died after a long hospitalization in the intensive care unit. Conclusion: Secondary spontaneous pneumothorax (SSP), as a complication in severe forms of COVID-19 pneumonia, especially in female patients without risk factors is rare, and early diagnosis and treatment are essential for increasing the survival chances of these patients.
