Gallbladder cancer is suspected preoperatively in only 30 % of all patients, while the other 70 % of cases are discovered incidentally by the pathologist (incidental or occult gallbladder cancer or IGBC). If gallbladder cancer is suspected preoperatively, an open cholecystectomy must be performed. The increasing rate of cholecystectomies via laparoscopy has lad to the detection of more gallbladder cancers in an early stage. Extended resection with regional lymph node dissection for T2 carcinomas and for more advanced cancer has been suggested. If IGBC is detected postoperatively by the pathologist after simple cholecystectomy, radical re-resection in cases of T2 tumours and more advanced stages is recommended. However, it has been argued that T1b cancers may have spread regionally or systemically at presentation and, thus, it remains debatable whether T1b cancers should be treated by simple cholecystectomy or by radical resection. PATIENTS / MATERIAL AND METHOD: This investigation was based on the German Registry of "Incidental Gallbladder Cancer" of the German Society of Surgery. In the present study, we evaluated whether T1 carcinoma patients do profit from a radical re-resection and if the different techniques of liver resection have comparable results in T1 carcinomas. ⋯ For T1a cancer a simple cholecystectomy is sufficient. An immediate re-resection is highly recommended for patients with IGBC in T1b stage. The wedge resection technique combined with a locoregional lymphadenectomy of the hepatoduodenal ligament seems to be the strategy of choice for T1b cancer. An extended re-resection is necessary to determine the nodal status exactly, and to determine an exact definite staging for patients with T1b cancer.

Following surgical procedures in thoracic surgery a chest X-ray is routinely performed and its necessity is rarely questioned. However, there are differences in the time frame of such radiological procedures. Especially after minor procedures such as mediastinoscopy there is a wide variation from a chest X-ray immediately after surgical intervention to an image only on the following day. Also, in some hospitals patients undergo only clinical but no radiological examination. No recommendations are available in the literature. ⋯ There are only sparse data concerning postoperative chest X-rays in thoracic surgery patients. In a study on children and young adults undergoing a Nuss procedure routine radiological examination was substituted by clinical indication resulting in a lower rate of thoracic drain placement. A chest X-ray to document the location of the metal bar prior to discharge was felt to be sufficient. In patients undergoing cardiac procedures daily routine chest X-rays on the intensive care ward were replaced by on-demand X-ray in a study without any change in length of stay, readmission or mortality. The same was found for chest X-rays following drain removal in cardiac patients: routine radiological examination seems not to be indicated. As a consequence of our own observational study on mediastinoscopy we have discontinued postoperative X-ray as the patients are examined clinically. All other patients undergoing thoracic surgery procedures who are observed in the intensive care unit receive the first chest X-ray in the morning following surgery. Only if complete expansion of the lung is warranted (pleurodesis, pneumothorax) an X-ray is performed on the day of surgery.

Randomized Controlled Trial Comparative Study
[Postoperative pain in the acute phase after surgery: VATS lobectomy vs. open lung resection - results of a prospective randomised trial].
Minimally invasive procedures, e.g. video-assisted thoracoscopic lobectomy, are less traumatic and thus one may expect a lower level of postoperative pain compared to open procedures. This assumption is supported by several studies/metaanalyses. However, confirmation by larger prospective randomised studies is lacking. In the present study we analysed 2 groups of patients with lobectomy for early-stage lung cancer performed by VATS or by antero-lateral thoracotomy. ⋯ Regardless of procedure (VATS vs. open) pain control can be achieved with an adequate analgetic regime. For VATS during the first days a lower amount of medication is required. The VATS group showed a higher proportion of patients with very low postoperative pain profile: patients with pain score always under 4 and patients without pain at certain points before the 10th postoperative day or at discharge.

Video-assisted thoracic surgery (VATS) procedures might reduce operative stress by minimising operative trauma. However VATS, in particular VATS lobectomy, is still associated with moderate acute postoperative pain. A gold standard for regional analgesia for VATS procedures has not yet surfaced, the studies published so far are very heterogeneous. ⋯ Although thoracic epidural analgesia (TEA) may not have been shown to be superior to other analgesic regimens, it is undoubtedly efficient as an analgesic treatment. With the increasing popularity of VATS procedures, there is growing demand from both surgeons and anaesthesiologists for an evidence-based approach to pain management for these procedures. Further studies on this topic are crucial to establish guidelines for pain management in VATS procedures.

The efficient and persisting treatment of the pain accompanying thoracic surgery is fundamental and beneficial for patients, since severe postoperative pulmonary complications and the incidence of chronic pain will be reduced. In this review the role of thoracic epidural analgesia in preventing and treating pain after thoracic surgery will be discussed critically and alternative strategies presented.
