RESUMEN
Objective:To investigate the clinical efficacy of bilateral route minimal- incision necrosectomy combined with continuous lavage for the treatment of infected necrotizing pancreatitis (INP).Methods:The retrospective and descriptive study was conducted. The clinical data of 20 patients with IPN who were admitted to Daping Hospital, Army Medical University from April 2016 to July 2019 were collected. There were 11 males and 9 females, aged (42±9)years. All the 20 patients underwent bilateral route minimal-incision necrosectomy, and then be continuous perfused and drainage within the purulent cavity postoperatively. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up using outpatient examination and telephone interview was performed to detected patients fever, abdominal pain, abdominal distension, diarrhea, peripancreatic residual infection and survival up to January 2020. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers. Results:(1) Surgical situations: of the 20 patients who underwent surgery successfully, 14 patients underwent upper abdomen combined with left retroperitoneal approach, 1 patient underwent upper abdomen combined with right retroperitoneal approach, and the other 5 patients underwent upper abdomen combined with bilateral retroperitoneal approach. Fourteen of the 20 patients underwent additional surgery including 10 cases undergoing jejunostomy, 2 cases undergoing gastrostomy combined with jejunostomy, 1 case undergoing laparoscopic cholecystectomy combined with jejunostomy, and 1 case undergoing cholecystectomy. The operation time and volume of intraoperative blood loss of 20 patients were (228±41) minutes and 100 mL (range, 50-700 mL), respectively. (2) Postoperative situations: 20 patients began continuous perfused with 0.9% sodium chloride solution within the purulent cavity at postoperative day 2 (range, day 1-14). Six of the 20 patients had postoperative complications including 1 case with postoperative gastric fistula combined with intraperitoneal hemorrhage who underwent laparotomy hemostasis combined with gastrostomy at day 13 postoperatively, 1 case with postoperative duodenal fistula who underwent gastrointestinal anastomosis and jejunostomy at day 111 postoperatively, 1 case with postoperative retroperitoneal residual tissue necrosis and infection who underwent peripancreatic necrotic tissue debridement and drainage at day 11 postoperatively, 1 case with postoperative gallbladder fistula who underwent cholecystectomy at day 71 postoperatively, and 2 cases with postoperative pancreatic fistula who were cured with conservative treatment. The duration of hospital stay after 1st operation of the 20 patients were 42 days (range,20-178 days). (3) Follow-up: all 20 patients were followed up for 6.0 to 45.0 months, with a median follow-up time of 14.5 months. During the follow-up, 1 case developed secondary diabetes, and none of patient showed clinical manifestation such as fever, abdominal pain, abdominal distension and diarrhea. The peripancreatic residual tissue of all 20 patients absorbed well, and none of patient died.Conclusion:Bilateral route minimal-incision necrosectomy combined with continuous lavage is safe and feasible for the treatment of INP.
RESUMEN
Objective To study the expression and clinical significance of the SALL4 in human gastric carcinoma tissues. Methods The expression of SALL4 in 91 samples of gastric carcinoma and 37 samples of normal gastric tissues was detected by RT-PCR,Western blot and immunohistochemistry,and its relationship with the clinical data were analyzed statistically.Results The positive expression rate of SALL4 in gastric carcinoma(74.7%)was significantly higher than that(18.9%)in normal gastric mucosa tissues(P <0.05).Moreover,with the decreased with the differentiation of gastric carcinoma,the positive expression rate of SALL4 was increased.The expression of SALL4 mRNA and protein in gastric carcinoma tissues were significantly higher than that in normal gastric tissues(P <0.050).The expression levels of SALL4 were relevant to lymph node metastasis(P =0.001),infiltra-tion depth(P =0.029)and the differentiation degree of gastric carcinoma(P =0.050).Conclusion SALL4 was highly expressed in gastric cancer tissues and relevant to lymph node metastasis,infiltration depth and the differentiation degree,which may have play an important role in the development of gastric cancer.
RESUMEN
Cultivating clinical comprehensive ability is one of the core and main purposes for surgical clinical education.According to the characteristics in clinical teaching of hepatobiliary surgery,we combined basic theory with clinical practice and discussed on the problems of how to improve medical students' clinical comprehensive abilities including clinical operational ability,logical thinking ability,scientific research innovative ability and the doctor-patient communication ability and how to cultivate medical ethics and professional competence from aspects of basic clinical skills training,translational medicine concept,etc.
RESUMEN
Pancreatoblastoma is a rare kind of malignant tumor of pancreas,which is commonly seen among children.A female child aged 5 years was admitted to the Dapiag Hospital with the chief complaint of painless abdominal mass on June 18,2010.The results of B ultrasound showed acoustic shadow of tumor calcification and an absent of normal pancreatic echo.The results of computed tomography(CT)showed that the tumor was located at the body and tail of the pancreas with a low-density and isopycnic shadow of intermixed huge block.The parenchyma of tumor showed unequal enhancement,the periphery showed lobular-like reticular enhancement,the central necrotic area showed no enhancement,and multiple metastatic foci were observed in spleen and liver under enhanced CT scan.The patient underwent resection of the body and tail of the pancreas and the spleen.Chemotherapeutics with vincristine,cyclophosphamide and doxorubicin were adopted postoperatively.After a period of 6-month follow-up,the results of CT showed that the size of tumor was decreased.
