Distribution of carnivorous benthic invertebrate in the northeastern part of Lutzow-Holm Bay, Antarctica
Benthic invertebrates were collected by bait traps at 35 stations scattered in the northeastern part of Lutzow-Holm Bay from May to September 1980. A total of 1103 carnivorous benthic invertebrates was obtained. They consisted of 41 species belonging to eight classes. Ophionotus victoriae was collected as many as 659 specimens occupying 59.7% of total invertebrates and Neobuccinum eatoni was the second in number. While, only one specimen was collected in 22 species out of 41 species. Species number tended to be larger in the shallow continental shelf than in the deep glacial trough. Species number was also large in the northern part of the study area compared with the southern part. The relation between the distribution of invertebrates and the bottom topography in a small area was studied in the Kita-no-ura Cove

Does modified Blumgart anastomosis without intra-pancreatic ductal stenting reduce post-operative pancreatic fistula after pancreaticojejunostomy?
Summary: Background: Post-operative pancreatic fistula (POPF) is one of the most common and serious complications after pancreaticoduodenectomy (PD). The aim of this study is to retrospectively compare clinically relevant (CR) POPF and other complications after pacreaticojejunostomy (PJ) after modified Kakita (m-Kakita) or modified Blumgart (m-Blumgart) anastomoses without stenting in a single institution. Methods: One hundred twenty-eight patients underwent PJ using m-Kakita anastomoses (two interrupted penetrating sutures) between January 2009 and December 2011. One hundred eighteen patients underwent m-Blumgart anastomoses (two transpancreatic/jejunal seromuscular sutures to cover the pancreatic stump with jejunal serosa) between January 2014 and December 2015. Demographics, clinical characteristics, and post-operative mortality and morbidity were retrospectively compared between the two groups. Results: There were no significant differences in demographics or clinical characteristics between the two groups except operative time. A significantly lower rate of CR-POPF was found in the m-Blumgart group relative to the m-Kakita group (10% vs. 19%, p = 0.038). Univariate and multivariate analyses revealed that the m-Blumgart anastomosis and fistula risk category (Negligible, Low) were independently protective against CR-POPF (p < 0.05). Conclusion: This retrospective single-center study demonstrated that the modified Blumgart method without pancreatic duct stenting was associated with a lower rate of CR-POPF.
