The clinical impact of combined pancreatoduodenectomy (PD) for advanced gallbladder cancer remains unclear. ⋯ Combined PD, including major HPD, is beneficial for selected patients of advanced gallbladder cancer; however, the indications should be carefully evaluated because of greater morbidity rates.

Limited data are available for pancreatic neuroendocrine carcinomas (NEC) defined by 2010 World Health Organization (WHO) criteria (mitotic count >20 mitoses/10 high-power fields and/or a Ki67 index of >20%), because most studies encompass heterogeneous cohorts of extrapulmonary/gastrointestinal NEC. Our aim was to evaluate the clinicopathologic characteristics, treatment, and prognosis of patients with pancreatic NEC defined by the 2010 WHO criteria. ⋯ Pancreatic NEC constitute a heterogeneous group of tumors. Although NEC is an aggressive disease, curative resection in localized disease is associated with improved survival. Morphologic WD pancreatic NEC represents a subgroup with what seems to be a markedly improved survival. Within the NEC category, tumor treatment should be individualized considering tumor morphology as well as the other 2010 WHO criteria.

Randomized Controlled Trial Comparative Study
Randomized prospective comparison of midline and off-midline closure techniques in pilonidal sinus surgery.
Pilonidal sinus is a chronic inflammatory disorder of the intergluteal sulcus. The disorder often negatively affects patients' quality of life, and there are numerous possible methods of operative treatment for pilonidal sinus. The aim of our study was to compare the results of 3 different operative procedures (tension-free primary closure, Limberg flap, and Karydakis technique) used in the treatment of pilonidal disease. ⋯ The search for an ideal treatment modality for pilonidal sinus disease is still ongoing. The main conclusion of our study is that a tension-free healing side is much more important than a midline suture line. Also, tension-free primary closure is as effective as a flap procedure, and it is also easier to perform.

Comparative Study
Complement C5a inhibition improves late hemodynamic and inflammatory changes in a rat model of nonocclusive mesenteric ischemia.
Nonocclusive mesenteric ischemia (NOMI) can evolve in a variety of low-flow states. Although the mechanisms leading to NOMI-related intestinal necrosis are largely unknown, circumstantial evidence suggests that excessive vasoconstriction and complement activation both play important roles in this process. Because targeting of the circulatory malfunction of the splanchnic area could be of therapeutic relevance, we set out to investigate the long-term effects of treatment with a complement C5a antagonist in a rat model of partial aortic occlusion (PAO)-induced transient mesenteric hypoperfusion. ⋯ C5a inhibition ameliorated the potentially harmful local mesenteric hypoperfusion and global long-term inflammatory consequences of PAO. This approach is of promise for use in NOMI-associated situations.
