Summary background data Right hemicolectomy can be performed using either a conventional open or a minimally invasive laparoscopic technique. It is not clear whether these different access routes differ with regard to short-term postoperative outcomes. Methods Patients documented in the German Society for General and Visceral Surgery StuDoQ|ColonCancer registry who underwent right hemicolectomy were analyzed regarding early postoperative complications according to Clavien-Dindo (primary endpoint), operation (OP) time, length of postoperative hospital stay (LOS), MTL30 and number of lymph nodes retrieved (secondary endpoints). Results A total of 4.997 patients were identified as undergoing oncological right hemicolectomy without additional interventions. Of these, 4.062 (81.3%) underwent open, 935 (18.7%) laparoscopic surgery. Propensity score analysis showed a significantly shorter LOS (OR: 0.55 CI 95%0.47-.64) and a significantly longer OP time (OR2.32 CI 1.98–2.71) for the laparoscopic route. Risk factors for postoperative complications, anastomotic insufficiency, ileus, reoperation and positive MTL30 were higher ASA status, higher age and increasing BMI. The surgical access route (open / lap) had no influence on these factors, but the laparoscopic group did have markedly fewer lymph nodes retrieved. Conclusion The present registry-based analysis could detect no relevant advantages for the minimally invasive laparoscopic access route. Further oncological analyses are needed to clarify the extent to which the smaller lymph node harvest in the laparoscopic group is accompanied by a poorer oncological outcome.

However, the role of adjuvant postoperative CTx (postCTx) in addition to neoadjuvant preoperative CTx (preCTx) in this setting remains controversial. Methods Between 4/2006 and 12/2013, 116 patients with locally advanced gastric cancer were treated with preCTx. 72 patients (62 %), in whom complete tumor resection (R0, subtotal/total gastrectomy with D2-lymphadenectomy) was achieved, were divided into two groups, one of which receiving adjuvant therapy (n = 52) and one without (n = 20). These groups were analyzed with regard to survival and exclusion criteria for adjuvant therapy. Results Postoperative complications, as well as their severity grade, did not correlate with fewer postCTx cycles administered (p = n.s.). Long-term survival was shorter in patients receiving postCTx in comparison to patients without postCTx, but did not show statistical significance. In per protocol analysis by excluding two patients with perioperative death, a shorter 3-year survival rate was observed in patients receiving postCTx compared to patients without postCTx (3-year survival: 71.2 % postCTx group vs. 90.0 % non-postCTx group; p = 0.038). Conclusion These results appear contradicting to the anticipated outcome. While speculative, they question the value of post-CTx. Prospectively randomized studies are needed to elucidate the role of postCTx.

Often, the physicians who first treat patients with ACC have no prior experience with the disease. The aim of our study was to evaluate the quality of medical care for patients with ACC in Germany. Methods: Data from the German ACC registry were analyzed with regard to the patients’ preoperative diagnostic evaluation, histopathological reporting, and clinical followup. The findings were compared with the recommendations of the European Network for the Study of Adrenal Tumors (ENSAT). Results: Data were analyzed from 387 patients who had been given an initial diagnosis of ACC in the years 1998 to 2009. 21% of them underwent no hormonal evaluation before surgery, and 59% underwent an inadequate hormonal evaluation. This exposed the patients to unnecessary perioperative risks and impaired their follow-up. 48% did not undergo CT scanning of the chest, even though the lungs are the most frequent site of metastases of ACC. For 13% of the patients, the diagnosis of ACC was later revised by a reference pathologist. For 11% of the patients, the histopathology report contained no information about resection status, even though this is an important determinant of further treatment and prognosis. Optimal management requires re-staging at three-month intervals, yet some patients underwent re-staging only after a longer delay, or not at all. Conclusion: We have identified significant deficits in the care of patients with ACC in Germany. We suspect that the situation is similar for other rare diseases. The prerequisite to better care is close and early cooperation of the treating physicians with specialized centers.
