Background: The incidence of gastric cancer has been increasing among elderly persons in Japan. This study aimed to clarify risk factors for postoperative complications in oldest old patients with gastric cancer., Methods: One-hundred ninety patients more than 75 years old with gastric cancer underwent gastrectomy between 2000 and 2011. Patients were classified into two groups: group A included 29 patients who were 85 years or older (oldest old patients), and group B included 161 patients who were 75-84 years of age. Perioperative parameters associated with complications were compared in each group., Results: The preoperative estimated glomerular filtration rate was significantly lower in group A (p = 0.03). The two groups significantly differed in performance status (p = 0.018). Patients in group A received a lesser extent of lymph node dissection and had fewer lymph nodes excised. As a result, the duration of the operation was significantly shorter in group A. There were no significant differences in the frequency or grade of total complications or mortality between the two groups. Operative hemorrhage (>300 ml) and Hiroshima POSSUM (predicted morbidity risk >40) were risk factors in both groups A and B; the risk factors of preoperative serum albumin level and prognostic nutritional index (PNI) were specific to group A., Conclusions: Adjustments to the extent of surgery among oldest old patients most likely reduces the incidence of postoperative complications in this group. Preoperative serum albumin level and PNI are significant predictors of postoperative complications in oldest old patients with gastric cancer.

Background: Delayed gastric emptying (DGE) is a common complication following left-sided hepatectomy. The goal of this study was to clarify the clinical implications of an omental flap wrapping procedure that includes fixation to the cut surface of the liver to reduce the incidence of DGE after left-sided hepatectomy., Methods: The study included 50 consecutive patients who underwent left-sided hepatectomy between January 2000 and July 2011. Clinicopathologic risk factors for DGE after left-sided hepatectomy were identified using univariate and multivariate models. The incidence of DGE, digestive symptoms, and postoperative complications were compared between two groups: 25 patients treated with the omental flap wrapping and fixation procedure and 25 patients who did not receive such a flap., Results: A univariate analysis revealed that a lack of the omental flap, the lymph node clearance, and use of left hemihepatectomy were associated with postoperative DGE. The multivariate analysis indicated that the lack of the omental flap was the only independent significant factor associated with the DGE (odds ratio, 21.23; p = 0.0002). There was a significant difference in the incidence of DGE between the patients with (4 %) and without an omental flap (36 %). The incidence of gastric distension and the use of prokinetic drugs were also significantly lower in patients with an omental flap than in patients without the flap, and patients with an omental flap resumed a solid diet significantly earlier., Conclusions: This retrospective single-center study revealed that it was possible to reduce the incidence of DGE using a procedure involving omental flap wrapping with fixation to the cut surface of the liver after left-sided hepatectomy.

Although extraperitoneal colostomy is often performed to prevent postoperative parastomal hernia formation following an open abdominoperineal resection of lower rectal cancer, it has not been widely employed laparoscopically because of the difficulty associated with the extraperitoneal route. This paper describes a laparoscopic extraperitoneal sigmoid colostomy using the Endo Retract™ Maxi instrument. This surgical technique is easy, and helps to prevent the development of parastomal hernias.

Background/purpose: A consistent predictor for pancreatic fistula (PF) development in the early period after pancreatic resection is still lacking., Patients and Methods: A total of 54 consecutive patients undergoing pancreatic resection were enrolled between June 2007 and April 2010. Pancreaticoduodenectomy (PD) and distal pancreatectomy (DP) were performed in 38 and 16 patients, respectively. For the purpose of finding an early predictor for PF development, we investigated drain amylase levels (d-Amy, IU/mL), drain output volume (d-Vol, mL/day) and drain amylase output (Amy-V, IU/day) on postoperative days (POD) 1 and 3. Amy-V was calculated as the product of d-Amy and d-Vol, and was expressed as the sum of values obtained from all drains. In addition, the ratio of d-Amy or Amy-V on POD3 to that on POD1 was calculated as the persisting ratio in each patient., Results: The overall incidence of clinical PF (International Study Group on Pancreatic Fistula Grade B and C) was 16.7%, occurring in 13.1% after PD and 25% after DP. All PF occurred in cases with a remnant pancreas of soft texture. There was no significant difference in d-Amy, d-Vol, or Amy-V on POD1 and POD3 between patients with and without clinical PF. The persisting ratio of Amy-V was significantly lower in patients without clinical PF compared to those with clinical PF (p = 0.029). Furthermore, the persisting ratio of Amy-V was significantly lower in patients with Grade A PF compared to those with Grade B PF (p = 0.03)., Conclusion: The persisting ratio of drain amylase output is a new significant predictive factor for clinical PF development., (© 2011 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)
