Pancreaticoduodenectomy combined with splenectomy for a patient with pancreatic cancer and pancytopenia due to liver cirrhosis: Case report

Introduction and importanceThe incidence of patients with liver cirrhosis (LC) is increasing. Patients with LC are known to have a greater risk of postoperative morbidity and mortality than patients without LC. A treatment option such as pancreaticoduodenectomy (PD) has not been validated to be safe for these patients, especially those with pancytopenia due to portal hypertension (PH). Providing an effective treatment option for these patients is essential.Case presentationHerein, we describe a patient with pancreatic cancer with pancytopenia due to LC that was successfully treated with PD combined with splenectomy. The patient was a 70-year-old woman who was referred to our hospital for evaluation of a mass in the pancreatic head after she developed obstructive jaundice. She was diagnosed with T2N0M0, Stage IB pancreatic cancer and pancytopenia due to PH associated with LC. She received 2 cycles of adjuvant gemcitabine/S-1 chemotherapy and underwent radical subtotal stomach-preserving pancreaticoduodenectomy with splenectomy to improve her pancytopenia. Histopathological examination of the resected specimen revealed an R0 resection showing an Evans grade IIa histological response. Her pancytopenia improved rapidly after surgery.Clinical discussionStrict indications for PD, haemostatic control of intraoperative bleeding, and optimal perioperative management were important for preventing hepatic decompensation in this patient. Splenectomy is effective for thrombocytopenia due to LC; however, attention to postoperative complications such as overwhelming post-splenectomy infection and portal vein thrombosis is required.ConclusionFor patients with pancreatic cancer with pancytopenia due to LC, PD combined with splenectomy plus optimal perioperative management is effective.     

胃肠胰腺神经内分泌肿瘤诊治进展

胃肠胰腺神经内分泌肿瘤是临床少见的恶性肿瘤,主要表现为过量分泌肿瘤相关物质所引起的症状,如皮肤潮红、轻度或者中度腹泻、右心瓣膜病变、哮喘、呼吸困难等疾病。多发生于中老年患者,且女性多于男性,呈现散发特点。多数患者无特异性临床症状,难以早期发现,降低了患者生存质量。胃肠胰腺神经内分泌瘤源于神经内分泌细胞的肿瘤,可起源于不同的神经内分泌器官。近年来,伴随着医学技术的不断发展,此疾病的诊断及治疗技术得到了提高。本文针对胃肠胰腺神经内分泌肿瘤诊断及治疗进行综述,以期提高此疾病诊治水平,为后续的相关临床实践研究提供参考依据。     

Intrapancreatic course of the splenic artery with combined pancreatic anomalies

Summary In a 47-year-old male cadaver the splenic artery traveled partially through the substance of the pancreas. Additionally, the pancreas was apparently large and had an unusual shape; the neck of the organ could not be differentiated; the uncinate processus was absent; two pancreatic ducts were present. The probable reason for this combined anomaly was abnormal fusion of the ventral and dorsal pancreatic buds due to different levels of origin.

Trajet intra-pancréatique de l'artère splénique associé à des anomalies pancréatiques

Résumé Sur le cadavre d'un homme de 47 ans, l'artère splénique présentait un trajet partiel à travers le pancréas. De plus, le pancréas paraissait volumineux et avait une forme inhabituelle, il n'était pas possible de différencier le col du pancréas, le processus uncinatus était absent, il y avait deux conduits pancréatiques. La raison probable de ces variations multiples se trouverait dans la fusion anormale des bourgeons pancréatiques dorsal et ventral en raison de leurs niveaux d'origine différents.

     

Anatomic basis of vascular distribution in combined removal of liver and pancreas (28.5.93)

Summary Based on the study of the arterial distribution of 120 hepatic grafts removed from brain-dead patients, the authors assess the possibilities of vascular partition in cases of combined removal of the liver and pancreas. The discussion deals with the vascular distribution of each organ. The presence of a right hepatic artery arising from the superior mesenteric a. (SMA) requires preservation of the SMA with the hepatic graft, while the pancreas is removed with the celiac trunk (CT) and its branches. The presence of a left hepatic artery arising from the CT requires its preservation with the hepatic graft, the pancreas being removed with the SMA and the splenic artery.

Partage vasculaire des prélèvements hépatiques et pancréatiques combinés : bases anatomiques (28.5.93)

Résumé A partir de l'étude de la distribution artérielle de 120 greffons hépatiques prélevés sur des patients en état de mort cérébrale, les auteurs apprécient les possibilités de partage vasculaire en cas de prélèvement combiné foie-pancréas. La discussion porte sur la distribution vasculaire de chaque organe. L'existence d'une artère hépatique droite naissant de l'artère mésentérique supérieure (AMS) nécessite de conserver l'AMS avec le greffon hépatique, le pancréas est prélevé avec le tronc coeliaque (TC) et ses branches. La présence d'une artère hépatique gauche naissant du TC impose de le conserver avec le greffon hépatique, le pancréas est prélevé avec l'AMS et l'artère splénique.

     

Effects of tri-iodothyronine (T3), insulin, insulin-like growth factor I (IGF-I) and transforming growth factor beta1 (TGFβ1) on the proportion of insulin cells in cultured embryonic chick pancreas

 With a view to ultimately identifying factors involved in the development of pancreatic insulin cells, we have cultured dorsal pancreatic buds from 5-day chick embryos on a basement membrane matrix (Matrigel) in a serum-free medium supplemented with selected factors. The endodermal components of the buds were freed of almost all the mesenchyme so as to eradicate as much as possible of this source of some such factors. In 7-day cultures, insulin and glucagon cells were demonstrated immunocytochemically; numbers of insulin cells were expressed as a percentage of insulin plus glucagon cell counts. Our standard medium contained insulin. Addition of tri-iodothyronine to this medium did not increase the proportion of insulin cells, but in combination with raised concentrations of glucose and essential amino acids it improved somewhat the marked increase previously recorded for these nutrient conditions. Omission of insulin from the standard medium greatly reduced the proportion of these cells; substitution of insulin by insulin-like growth factor I increased the proportion considerably more than did insulin. To test for an overall effect of growth factors, explants were cultured in standard medium on Matrigel containing reduced amounts of growth factors: the proportion of insulin cells proved to be increased over that reached on normal Matrigel. The suspicion that transforming growth factor β1, a component of Matrigel, might act to reduce the proportion of insulin cells was tested and found to be correct. It is suggested that the different factors studied here may affect either or both of proliferation and determination in the differentiation pathway of insulin vis-à-vis glucagon cells.

小儿假性胰腺囊肿的诊断和治疗

目的探讨准确地诊断和治疗小儿假性胰腺囊肿.方法总结近10年来我们收治经B超、钡餐、CT和MRI以及手术证实的假性胰腺囊肿15例.结果发现15例中男11例,女4例,年龄最小1岁4个月,最大13岁,平均年龄9.4岁.而且7例有明显外伤史(7/15,占40%),恶心呕吐(14/15,占93%)、腹痛(11/15,占73%),腹部肿块(10/15,占66%)为主要临床表现,其次有发热、消瘦、贫血.此外,在诊断上除依靠病史、体检和临床表现外,B超是最适宜和有价值的诊断依据,钡餐、CT和MRI可以帮助诊断和鉴别诊断,还发现一旦血清淀粉酶下降后又重新回升,不但对确诊有重要意义,也是手术的重要指证.14例接受手术治疗患儿均恢复良好,无1例死亡.结论①小儿假性胰腺囊肿诊断除主要依靠病史、体征外,B超对小儿仍是有价值的辅助检查,诊断困难时可结合钡餐、CT和MRI加以鉴别.②小儿假性胰腺囊肿多与外伤有关,男＞女,因男孩好动、顽皮受伤机率多.③囊肿形成超过6周,或者B超显示囊肿壁形成明显时应选用内引流手术,较大囊肿仅外引流难以治愈.     

Einfluβ bildgebender diagnostischer verfahren auf therapiewahl und prognose traumatischer pankreas- und duodenalverletzungen

27 patients with pancreatic and 8 with duodenal injuries were studied, 66% of whom had associated abdominal injuries. Peritoneal lavage was performed in 10 cases, and ultrasonography in 15. Laparotomy was considered to be indicated on the basis of the results in 9 cases of peritoneal lavage and in 12 cases of ultrasound examination, but in only 1 case and 2 cases, respectively, did the findings constitute the only reason for performing a laparotomy. Pancreatic and duodenal injuries were directly confirmed by ultrasonography and computer tomography only in a minority of cases. The morbiditiy of pancreatic and duodenal injuries was 66% and 25%, respectively, and lethality, 19% and 25%. Despite modern imaging techniques, clinical examination is of paramount importance for the decision as to whether operative therapy is indicated; delay leads to increased morbidity and lethality.     

Intracisternal injection of TRH antibody blocks gastric emptying stimulated by 2-deoxy-d-glucose in rats

We evaluated the effect of 2-deoxy-d-glucose (2-DG) on gastric emptying of a non nutrient solution in conscious rats using a Phenol red method. Intravenous injection of 2-deoxy-d-glucose dose-dependently increased the rate of gastric emptying. This stimulatory action of 2-DG was abolished by subdiaphragmatic vagotomy. Intracisternal injection of thyrotropin-releasing hormone (TRH) antibody blocked intracisternal TRH and intravenous 2-DG-induced enhancement of gastric empyting but not the stimulation of gastric emptying induced by intracisternal pancreatic polypeptide. The TRH antibody injected intraperitoneally had no effect. These results suggest that endogenous TRH in the brain is involved in vagal-dependent stimulation of gastric emptying by 2-DG.
