ABSTRACT
A total of 1 789 patients with gastric cancer underwent radical gastrectomy in our hospital from September 2015 to August 2017, internal hernia (IH) developed in 7 cases with a incidence rate of 0.4%. The general condition, the symptoms, imaging findings, treatment methods and prognosis as well as the types of digestive tract reconstruction of patients were retrospective analyzed. There were 4 cases of Petersen′s hernia, 2 cases of jejuno-jejuno mesenteric hernia and 1 case of diaphragm hernia. All patients developed mechanical obstruction. Imaging examination showed mesenteric vessels overriding sign and double whirl sign. Six patients recovered smoothly, 1 patient gave up treatment due to extensive small bowel infarction. It is indicated that the formation of abnormal channels in the abdominal cavity after radical gastrectomy may lead to IH. The mesenteric vessels overriding sign and the double whirl sign are the unique imaging findings of IH after radical gastrectomy. Closing the abnormal channel can prevent the occurrence of IH after gastrectomy.

ABSTRACT
Objective To investigate the clinical outcomes of radical surgery for pancreatic body and tail tumors accompanied with sinistral portal hypertension (SPH).Method The clinicopathological data of 35 patients with pancreatic body and tail tumors accompanied with SPH operated from January 2004 to December 2014 were retrospectively analyzed.Results Of 35 patients,22 patients had body and tail pancreatic carcinomas,10 patients had malignant solid pesudopaillary tumors and 1 patients had a neuroendocrine tumor.All these patients developed splenomegaly and varices in the gastric fundus with normal hepatic function.The splenic vein pressure was (27.3 ±3.8)cmH2O (1 cmH2O =0.098 kPa),its average diameter was (1.3 ± 0.3) cm,and the speed of splenic vein blood flow was (8.9 ± 0.8) cm/s.Of the 35 patients with pancreatic body and tail tumors who underwent radical resectional operations,22 patients in addition underwent devascularization.There were 13 of these 22 patients who underwent pericardical devascularization and the remaining 9 underwent total or proximal gastrectomy.The main complications were pancreatic fistula (n =5,14.2％),intra-abdominal infection (n =4,11.5％),delayed gastric emptying (n =1,2.8％),lymphatic fistula (n =1,2.8％) and gastric perforation (n =1,2.8％).The post-complication morbidity rate was 34％.All these patients were followed-up for 6 to 60 months after operations.There was no upper gastrointestinal bleeding which occurred within 6 months of operation.Conclusion Multi-disciplinary treatment,complete preoperative evaluation,correct perioperative and individualized management enhanced efficacy in the surgical treatment of patients with pancreatic body and tail tumors with SPH.
ABSTRACT
Objective To investigate the clinical efficacy of radical operation for gastric cancer with liver cirrhosis.Methods The clinicopathological data of 56 gastric caner patients with liver cirrhosis performed on between Jan 2000 and Dec 2013 were analyzed retrospectively.Results The morbidity rate was 71％.The main complications of the group with liver cirrhosis were postoperative ascites (7 cases),delayed gastric emptying(6 cases),pulmonary infection(8 cases),intra-abdominal infection (5 cases),anastomotic leakage (3 cases).wound infection (2 cases)and,astrointestinal bleeding(1 cases).Postoperative complications of gastric cancer with liver cirrhosis were associated with age (＞ 60 yrs),Child-pugh grade(B),lymph node dissection(D2).There were no mortality.The 1-,3-and 5-year survival rates of the 56 cases were 73.2％,41％ and 26.7％.Conclusion Multi-disciplinary treatment,complete preoperative evaluation,correct perioperative management,individualized principle were the best mode on effective treatment of the patients with liver cirrhosis.
ABSTRACT
Objective To assess the effect of three different liver vascular exclusions on prognosis of patients undergoing hemihepatectomy.Methods Clinical data of 216 patients undergoing hemihepatectomy were analyzed retrospectively.Ninety-eight out of 216 patients received Pringle maneuver during hepatectomy in group A,71 patients of selective liver inflow and outflow vascular exclusions in group B,47 patients using liver hanging maneuver combining with selective liver inflow and outflow vascular exclusions were in group C.Results There was no difference in operation time between the three groups ( t =0.72,0.83,and 0.67,P ＞ 0.05 ).The intraoperative blood loss and transfusion in group B and C were less than that in group A (t =3.72,3.83 and 4.11,4.07,P ＜0.05).Serum albumin level on day 1 and day 3 in group B and C were higher than that in group A (t =3.65,3.77,and 3.90,3.74,P ＜0.05 ).Serum total bilirubin level on day 3 and 5 in group B and C were lower than that in group A ( t =4.13,5.01,and 4.09,3.99,P ＜0.05).Serum alanine aminotransferase on day 1,3 and 5 in group B and C were lower than that in group A ( t =5.36,6.14,and 5.70,7.01,and 4.94,3.98,P ＜ 0.05 ).Postoperative complication rate in group A was higher than that in group B and C ( x2 =13.71 and 23.56,P ＜ 0.05 ).The 3-year survival rate of patients with malignant tumor in the three groups were not significantly different (t =2.38,P ＞ 0.05 ).Conclusions Intraoperative blood loss and transfusion and postoperative complication rate can be reduced,and liver injury can be diminished in hemihepatectomy using selective liver inflow and outflow vascular exclusion alone and or in combination with a liver hanging maneuver.
ABSTRACT
Objective To evaluate the result of multiple segmentectomy under selective occlusion of hepatic inflow for complicated intrahepatic cholangiolithiasis. Methods In this study 12 cases of complicated intrahepatic cholangiolithiasis receiving multiple segmentectomy under selective occlusion of hepatic inflow during 2004. 1 - 2010. 10 were reviewed retrospectively. The short-term and long-term outcomes of the patients were analyzed. Results There was no surgical mortality in this group. The segmentectomy performed were Ⅱ + Ⅲ + Ⅴ in 1 case; Ⅱ + Ⅲ + Ⅵ in 2 cases; Ⅱ + Ⅲ + Ⅴ + Ⅵ in 1 case;Ⅱ +Ⅲ+Ⅵ +Ⅶ in4 cases; Ⅱ +Ⅲ +Ⅳ +Ⅵ in 3 cases and Ⅱ + Ⅲ +Ⅳ +Ⅵ +Ⅶ in 1 case. The average intraoperative blood loss was 560 ± 291 ml. Postoperative complications were wound infection in 2 cases, bile leakage in 1 case, abdominal infection in 1 case. There were no liver failure, intrabdominal hemorrhage or hemobilia; stone clearance rate at 10 days after operation was 83% (10/12) and 92%(11/12) at 6 weeks after operation following postoperative choledochoscopic lithotripsy. 92% (11/12) cases were followed-up with the median follow-up period of 31 months. The result was excellent or good in 92% (11/12) cases. Conclusions Multiple segmentectomy was the choice for complicated intrahepatic cholangiolithasis, and the procedure could be safely performed under selective occlusion of the hepatic inflow.
