Two-stage laparoscopic transversus abdominis plane block as an equivalent alternative to thoracic epidural anaesthesia in bowel resection-an explorative cohort study.

PURPOSE: We evaluated the effect of the two-stage laparoscopic transversus abdominis plane block (TS-L-TAPB) in comparison to thoracic epidural anaesthesia (TEA) and a one-stage L-TAPB (OS-L-TAPB) in patients who underwent elective laparoscopic bowel resection. METHODS: We compared a TS-L-TAPB (266 mg bupivacaine), which was performed bilaterally at the beginning and end of surgery, with two retrospective cohorts. These were patients who had undergone a TEA (ropivacaine/sufentanil) or an OS-L-TAPB (200 mg ropivacaine) at the beginning of surgery. Oral and i.v. opiate requirements were documented over the first 3 postoperative days (POD). RESULTS: Patients were divided into three groups TEA (n = 23), OS-L-TAPB (n = 75), and TS-L-TAPB (n = 49). By the evening of the third POD, patients with a TEA had a higher cumulative opiate requirement with a median of 45.625 mg [0; 202.5] than patients in the OS-L-TAPB group at 10 mg [0; 245.625] and the TS-L-TAPB group at 5.625 mg [0; 215.625] (p = 0.1438). One hour after arrival in the recovery room, significantly more patients in the TEA group (100%) did not need oral and i.v. opioids than in the TS-L-TAPB (78%) and OS-L-TAPB groups (68%) (p = 0.0067).This was without clinical relevance however as the median in all groups was 0 mg. On the third POD, patients in the TEA group had a significantly higher median oral and i.v. opioid dose at 40 mg [0; 80] than the TS-L-TAPB and OS-L-TAPB groups, both at 0 mg [0; 80] (p = 0.0009). CONCLUSION: The TS-L-TAP showed statistically significant and clinically meaningful benefits over TEA and OS-L-TAP in reducing postoperative opiate requirements.

[Pneumothorax, what kind of therapy is necessary? A clinical overview]. / Pneumothorax, welche Therapie ist notwendig? Ein klinischer Überblick.

Pneumothorax is defined as the accumulation of air in the pleural space. A distinction is made between a primary (idiopathic) spontaneous pneumothorax (PSP), secondary spontaneous pneumothorax (SSP) as well as between iatrogenic pneumothorax and traumatic pneumothorax. Primary spontaneous pneumothorax (PSP) occurs mainly in otherwise healthy people (mainly tall and thin young men) without any clinical sign of lung disease. In contrast, secondary pneumothorax (SSP) mostly occurs in patients with diagnosed and clinically manifested lung disease and is most frequent in older subjects (> 50 years). Smokers have a higher risk of developing pneumothorax. Most pneumothorax cases require a therapeutic intervention using thorax drainage. Observation alone is recommended for only those few patients suffering from pneumothorax without clinical symptoms. Although simple needle aspiration is often recommended as a first-line treatment, our clinical experience shows no advantage for most of the patients. All patients with symptomatic pneumothorax should be treated with immediate intercostal tube drainage. In the surgical therapy of pneumothorax, VATS (video-assisted thoracic surgery) is the current effective standard treatment. Open posterolateral thoracotomy is the recommend approach rather than the minimally invasive procedure in patient with serious illness or complications. The aim of both interventions is to reduce the recurrence rate of pneumothorax as much as possible.

Sleeve resections for the treatment of non-small cell lung cancer.

Parenchyma-sparing sleeve lobectomies were originally developed as a surgical strategy for patients not fit for a pneumonectomy, because of impaired pulmonary function. As promising short- and long-term results were demonstrated, sleeve lobectomy was accepted as an alternative surgical procedure to pneumonectomy. Nowadays, sleeve resections are associated with prolonged long-term survival and better quality of life, compared to pneumonectomy. Therefore, sleeve resections should be performed for centrally located non-small cell lung cancer (NSCLC) whenever technically, anatomically and oncologically possible. In this review, we discuss the current status of sleeve resections in the management of NSCLC.

[Intrathoracic injuries]. / Intrathorakale Verletzungen.

Severe intrathoracic injuries are uncommon but immediately life-threatening. These injuries are mostly associated with polytrauma. After stabilization of polytraumatized patients imaging is a prerequisite for treatment and operation planning. The assessment warrants an interdisciplinary approach primarily between the specialties of anesthesia, trauma surgery and thoracic surgery and further specialties should be involved depending on the injury pattern. This article gives an overview about the current management of the most important intrathoracic injuries.

[Diagnostic assessment and treatment concepts for thoracic trauma]. / Diagnostik und Behandlungskonzepte beim Thoraxtrauma.

Most patients with chest trauma can be successfully treated with tube thoracostomy and appropriate pain medication. Initial care of these patients is usually straightforward and performed by an emergency doctor or an emergency room surgeon, e.g. a general surgeon. If more extensive therapy of these polytraumatized patients appears to be required, tertiary care should be done in specialized centers or clinics with network structures. An appropriate structured network of surgical centers guarantees sufficient and efficient care of patients with severe chest trauma. In a best-case scenario the specialist disciplines work in a rendezvous system with close cooperation. Early communication with a thoracic surgeon is essential to minimize mortality and long-term morbidity. Improvement in understanding the underlying molecular physiological mechanisms involved in the various traumatic pathological processes and the advancement of diagnostic techniques, minimally invasive approaches and pharmacologic therapy, will contribute to decreasing morbidity of these critically injured patients.
