Impact of Neoadjuvant Chemotherapy on Postoperative Morbidity after Gastrectomy for Gastric Cancer

Background/Aims: Patients with locally advanced gastric cancer benefit from neoadjuvant chemotherapy. Potential disadvantages of neoadjuvant chemotherapy include increased surgical complications, leading to increased postoperative morbidity. Methods: We retrospectively studied medical records of 135 patients with resectable cancer of the stomach who underwent gastrectomy between 2002 and 2009. The impact of neoadjuvant chemotherapy on postoperative morbidity was investigated. We compared demographic, clinical and operative data, morbidity and mortality from 105 patients who received surgical treatment immediately after diagnosis (SURG group), versus 30 patients who first received neoadjuvant chemotherapy (CHEMO group). Results: Demographic, clinical and surgical procedure parameters did not differ significantly between both groups. Postoperative morbidity was 46.7% in CHEMO- and 41.9% in SURG-patients (p = 0.680). There were eight cases of death, 2/30 (6.7%) in CHEMO and 6/105 (5.7%) in the SURG group (p = 1). The overall complications according to Clavien- classification did not differ significantly (p = 0.455). The wound infection rate (23.3 vs. 3.8%; p = 0.002) and insufficiency of the duodenal stump (13.3 vs. 1.9%; p = 0.022) were significantly higher in the CHEMO group. Conclusion: This study showed no significant impact of neoadjuvant chemotherapy on postoperative morbidity after gastrectomy using the Clavien-classification. Only an increase in wound infections in CHEMO compared with the SURG group were noted. Therefore, neoadjuvant chemotherapy can be considered safe and feasible

The Clavien-Dindo Classification in Pancreatic Surgery: A Clinical and Economic Validation

Background/Aims: In 2004 P. A. Clavien and D. Dindo published the well-known grading system of postoperative complications. It is established in several surgical disciplines. The aim of this study was to assess its validity in pancreatic surgery. The impact of complication grade on economic resources was investigated as well. Methods: From a prospective database, we retrospectively evaluated all patients who underwent pancreatic resection between January 2009 and December 2014 at our department. 309 patients received pancreatic head resection (pylorus-preserving pancreatoduodenectomy (PPPD) or Kausch-Whipple), total pancreatectomy or left resection. We performed a univariate analysis of the correlation between the Clavien-Dindo classification-grade (CDC-grade) with length of postoperative stay (LOS) and DRG-related (diagnosis related groups) remuneration using Kruskal-Wallis test. Furthermore, we performed a subgroup analysis (chi-square test and Fishers-test) of demographic, clinical, and perioperative data. Results: American Society of Anesthesiologists (ASA) score (p = 0.0014), operation time (p = 0.0229) and intraoperative blood loss (p = 0.0016) showed significant correlation with CDC-grade. Increasing LOS and DRG-related remuneration correlated significantly with increasing CDC-grade (p < 0.0001). Conclusion: The CDC-grading system shows high correlation to clinical outcome and case-related remuneration in pancreatic surgery. Therefore, it is a valid tool for evaluation and comparison of surgical techniques and surgical centers

Clinical pathways for oncological gastrectomy: are they a suitable instrument for process standardization to improve process and outcome quality for patients undergoing gastrectomy? A retrospective cohort study

(1) Background: Oncological gastrectomy requires complex multidisciplinary management. Clinical pathways (CPs) can potentially facilitate this task, but evidence related to their use in managing oncological gastrectomy is limited. This study evaluated the effect of a CP for oncological gastrectomy on process and outcome quality. (2) Methods: Consecutive patients undergoing oncological gastrectomy before (n = 64) or after (n = 62) the introduction of a CP were evaluated. Assessed parameters included catheter and drain management, postoperative mobilization, resumption of diet and length of stay. Morbidity, mortality, reoperation and readmission rates were used as indicators of outcome quality. (3) Results: Enteral nutrition was initiated significantly earlier after CP implementation (5.0 vs. 7.0 days, p < 0.0001). Readmission was more frequent before CP implementation (7.8% vs. 0.0%, p = 0.05). Incentive spirometer usage increased following CP implementation (100% vs. 90.6%, p = 0.11). Mortality, morbidity and reoperation rates remained unchanged. (4) Conclusions: After implementation of an oncological gastrectomy CP, process quality improved, while indicators of outcome quality such as mortality and reoperation rates remained unchanged. CPs are a promising tool to standardize perioperative care for oncological gastrectom

Influence of clinical pathways on treatment and outcome quality for patients undergoing pancreatoduodenectomy? – a retrospective outcome cohort study

Background: Pancreatic surgery demands complex multidisciplinary management. Clinical pathways (CPs) are a tool to facilitate this task, but evidence for their utility in pancreatic surgery is scarce. This study evaluated the effect of CPs on quality of care for pancreatoduodenectomy. Methods: Data of all consecutive patients who underwent pancreatoduodenectomy before (n = 147) or after (n = 148) CP introduction were evaluated regarding catheter and drain management, postoperative mobilization, pancreatic enzyme substitution, resumption of diet and length of stay. Outcome quality was assessed using glycaemia management, morbidity, mortality, reoperation and readmission rates. Results: Catheters and abdominal drainages were removed significantly earlier in patients treated with CP (p 3 was significantly higher in the CP group (p < 0.0001). There was no significant difference in mortality, morbidity, reoperation and readmission rates. Conclusions: Following implementation of a CP for pancreatoduodenectomy, several indicators of process and outcome quality improved, while others such as mortality and reoperation rates remained unchanged. CPs are a promising tool to improve quality of care in pancreatic surgery
