Is Laparoscopy-assisted Radical Gastrectomy Safe in Patients with Child-Pugh Class A Cirrhosis?

PURPOSE: We investigated early postoperative morbidity and mortality in patients with liver cirrhosis who had undergone radical gastrectomy for gastric cancer. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 41 patients who underwent radical gastrectomy at the Chonnam National University Hwasun Hospital (Hwasun-gun, Korea) between August 2004 and June 2009. There were few patients with Child-Pugh class B or C; therefore, we restricted patient selection to those with Child-Pugh class A. RESULTS: Postoperative complications were observed in 22 (53.7%) patients. The most common complications were ascites (46.3%), postoperative hemorrhage (22.0%) and wound infection (12.2%). Intra-abdominal abscess developed in one (2.4%) patient who had undergone open gastrectomy. Massive ascites occurred in 4 (9.8%) patients. Of the patients who underwent open gastrectomy, nine (21.9%) patients required blood transfusions as a result of postoperative hemorrhage. However, most of these patients had advanced gastric cancer. In contrast, most patients who underwent laparoscopic gastrectomy had early stage gastric cancer, and when the confounding effect from the different stages between the two groups was corrected statistically, no statistically significant difference was found. There was also no significant difference between open and laparoscopic gastrectomy in the occurrence rate of other postoperative complications such as ascites, wound infection, and intra-abdominal abscess. No postoperative mortality occurred. CONCLUSIONS: Laparoscopic gastrectomy is a feasible surgical procedure for patients with moderate hepatic dysfunction.

Definition and classification of complications of gastrectomy for gastric cancer based on the accordion severity grading system.

BACKGROUND: Postoperative complications still comprise the marker used most frequently to assess the quality of gastrectomy. However, the definition and grading of morbidity is not standardized, hampering meaningful comparisons over time and among centers. This study proposes specific definitions and a reproducible classification of complications following gastrectomy using standardized grading tools. METHODS: We defined each complication based on the literature, and adopted the Accordion Severity Grading System to stratify morbidity. The classification was applied to 890 patients with gastric cancer seen between January 2010 and April 2011. The correlation between the complication grades and the length of hospital stay (LOS) was analyzed, and risk factors for complications were examined with special reference to severity grade. RESULTS: The overall morbidity rate was 18.1 %. Mild complications occurred in 31 patients (3.5 %), moderate in 77 patients (8.7 %), severe--invasive procedure/no general anesthesia (GA) in 27 patients (3.0 %), severe--invasive procedures/GA in 18 patients (2.0 %), and severe--organ failure in 3 patients (0.3 %). Five patients (0.6 %) died postoperatively. The grade of complications had a significant effect on the LOS (p < 0.001). Operating time and cardiovascular and pulmonary co-morbidities were independent risk factors for severe complications [odds ratio (OR) 1.001, p = 0.016; OR 2.226, p = 0.006; OR = 2.896, p = 0.003, respectively]. CONCLUSIONS: The complications after gastrectomy could be classified into different severity grades that had distinct clinical outcomes. The use of this classification provides more reliable, practical outcome data. Consequently, complications should be reported using a standardized classification tool such as the Accordion Severity Grading System, which requires consensus on the definition of specific complications.

Modified radical lymphadenectomy without splenectomy in patients with proximal gastric cancer: comparison with standard D2 lymphadenectomy for distal gastric cancer.

BACKGROUND AND OBJECTIVES: We assessed the optimal extent of lymph node dissection and the effect of splenectomy in patients with proximal gastric cancer. METHOD: Recurrence and survival rates were compared between 881 patients with proximal gastric cancer who underwent modified radical lymphadenectomy and 3,098 patients with distal gastric cancer who underwent standard D2 lymphadenectomy. RESULTS: The recurrence rate was significantly higher in the total than in the distal gastrectomy group (32.5% vs. 16.5%, P < 0.001), but the rates were similar after adjustment for TNM stage. The overall 5-year survival rate was significantly higher in the distal than in the total gastrectomy group (80.4% vs. 66.2%, P < 0.001), but this difference was not observed after adjustment for TNM stage. Multivariate analysis showed that patient age, number of retrieved lymph nodes, depth of invasion, and nodal metastasis were independent prognostic determinants for survival, whereas type of lymphadenectomy was not. CONCLUSION: Long-term outcomes were similar in patients with proximal gastric cancer who underwent modified lymphadenectomy without splenectomy and in patients with distal gastric cancer who underwent standard D2 lymphadenectomy. These findings indicate that modified radical lymphadenectomy without splenectomy is sufficient for optimal lymph node dissection in patients with proximal gastric cancer.
