Objective To summarize the experiences of middle pancreatectomy. Methods Eleven female and 4 male with a mean age of 49.4 years (23.8-73.1 years) who underwent middle pancreatectomy from January 2001 to October 2005 were collected. Eight patients with neuroendocrine tumor (non-function of 5 cases), 5 with serous cystadenomas and 2 with mucinous cystadenomas were included. The proximal apical end of pancreas was sutured, while distal end of pancreas was anastomosed to a Roux-en-Y jejunal loop. Results Mean operative time was 275 min (179-370 min), mean length of resected pancreas was 45 mm (30-60 mm) and max diameter of tumor was 23 mm (15-40 mm). Complication after operation was pancreatic fistula 〔4 cases (26.7%)〕, in which 3 cases (20.0%) had intraabdominal blood. The mean time of follow-up was 23 months (3 months-5 years). one patient was died of multiple organs failure for pulmonary infections in month 3 after operation, and the others were alive without novo-diabetes. Conclusion Middle pancreatectomy is an effective operation for benign and borderline tumors of neck and body of pancreas without a significant increase of postoperative morbidity.
Objective To explore the important role of preperitoneal space in laparoscopic transabdominal preperitoneal （TAPP） and totally extraperitoneal （TEP） hernia repair. Methods The clinical data of 66 patients （78 sides） performed laparoscopic TAPP and TEP hernia repair from January 2008 to April 2011 in this hospital were analyzed retrospectively. Results TAPP hernia repair were performed in 16 cases （20 sides），TEP hernia repair were performed in 50 cases （58 sides）. Three cases of TEP hernia repair transferred to TAPP hernia repair. The unilateral operation time was （86.92±36.38） min，intraoperative bleeding was （6.08±3.43） ml. Postoperative complication rate was 16.7% （11/66），including 3 cases of postoperative serum swelling，3 cases of temporary paraesthesia of nerve feeling in the repair area，2 cases of scrotum emphysema，2 cases of urinary retention，and 1 case of intestinal obstruction. There were 2 cases of recurrence. The hospital stay was （4.52±0.99） d. The return to activities and working time was （10.32±1.86） d after discharge. Sixty-six cases were followed up for （18.56±1.96） months （range 1-38 months），the patch infection，chronic pain，and testicular atrophy complications were not been observed. Conclusions Acquainting and mastering laparoscopic preperitoneal space and its important structure are the key to avoid intraoperative and postoperative complications of laparoscopic inguinal hernia repair.
ObjectiveTo discuss application of " counter clockwise resection” in total laparoscopic pan-creaticoduodenectomy (TLPD) and summarize it’s preliminary experiences.MethodThe clinical data of consecutive 8 patients underwent TLPD in the Department of Pancreatic Surgery, Affiliated Shengjing Hospital of China Medical University from July 2016 to January 2017 were analyzed retrospectively.ResultsThere were 3 males and 5 females in these 8 patients. The age was (64.13±15.01) years. The results of postoperative pathology included 1 duodenal cancer, 2 distal biliary tract cancers, 4 pancreatic head cancers, and 1 solid pseudopapillary tumor of pancreatic head. All the 8 patients were performed with TLPD successfully, and the time of the operation was (527.50±69.44) min, the resection time of the specimen was (241.25±38.71) min, and the blood loss was (368.75±162.43) mL, the postoperative hospitalization stay was (18.67±4.00) d. There were no postoperative bleeding, perioperative death, and delayed gastric emptying．Four patients suffered from the pancreatic fistula including 3 cases of grade A and 1 case of grade B pancreatic fistulas, and 1 case suffered from the intra-abdominal infection, who were cured after the conservative treatment. All the patients were following-up, and there was no abnormality.ConclusionPreliminary results of limited cases in this study show that " counter clockwise resection” might be a safe, effective, and easy method of TLPD, but further research is need to study.
Objective To review the effects of pulmonary surfactant in adult patients with acute lung injury ( ALI) /acute respiratory distress syndrome ( ARDS) . Methods Randomized controlled trials ( RCTs) were recruited from PubMed ( 1966.1-2011.3) , ISI Web of Knowledge ( all the years) and Wanfang Database ( 1982-2011) . Related published data and attached references were hand searched. All the RCTs about pulmonary surfactant for the adult patients with ALI/ARDS were included, then a meta-analysis was performed. Results Eight eligible trials were enrolled. Pooled analysis showed that treatment with pulmonary surfactant was not associated with reduction in 28 or 30-day mortality compared with the control group [ OR 1.05, 95% CI ( 0.90, 1.22 ) , P = 0.55] , neither did subgroup analysis in the pneumoia/ aspiration, sepsis, and trauma/ surgery induced ALI/ARDS patients. Three RCTs showed the oxygenation was significantly improved in adult ALI/ARDS patients receiving pulmonary surfactant compared with the control group( Plt;0.05) . Shorter mechanical ventilation days was shown in the ALI/ARDS patients receiving pulmonary surfactant in one RCT(Plt;0.05) . Conclusions Meta-analysis showed pulmonary surfactant did not reduce the 28 or 30-day mortality of adult patients with ALI/ARDS, however, improved the oxygenation. Pulmonary surfactant can be considered a therapy in ALI/ARDS.
Objective To summarize preliminary experience of laparoscopic pancreaticoduodenectomy for periampullary carcinoma. Method The clinical data of patients with periampullary carcinoma underwent laparoscopic pancreaticoduodenectomy from July 2016 to September 2016 in the Shengjing Hospital of China Medical University were analyzed retrospectively. Results Two patients underwent complete laparoscopic pancreaticoduodenectomy, 2 patients underwent laparoscopic resection and anastomosis assisted with small incision open. The R0 resection and duct to mucosa pancreaticojejunal anastomosis were performed in all the patients. The operative time was 510–600 min, intraoperative blood loss was 400–600 mL, postoperative hospitalization time was 15–21d, postoperative ambulation time was 6–7 d. Three cases of pancreatic fistula were grade A and all were cured by conservation. No postoperative bleeding, delayed gastric emptying, intra-abdominal infection, and bile leakage occurred. The postoperative pathological results showed that there was 1 case of pancreatic head ductal adenocarcinoma, 1 case of cyst adenocarcinoma of pancreas uncinate process, 1 case of papillary carcinoma of duodenum, and 1 case of terminal bile duct carcinoma. Conclusion The preliminary results of limited cases in this study show that laparoscopic pancreaticoduodenectomy has been proven to be a safe procedure, it could reduce perioperative cardiopulmonary complications, its exhaust time, feeding time, and postoperative ambulation time are shorter, but its operative complications could not be reduced.
Objective To investigate the cause, treatment, and prognosis of the postpancreaticoduodenectomy hemorrhage (PPH) . Method A total of 779 patients who underwent pancreaticoduodenectomy at Fudan University Shanghai Cancer Center between January 2015 and December 2016 were enrolled, and the data of them were retrospectively analyzed. Results Sixteen patients (PPH group) suffered from PPH and 763 patients didn’t suffered from PPH (non-PPH group) of 779 patients. There was no significant difference in the age, gender, type of disease, operative time, blood loss, and ratio of blood transfusion between the 2 groups (P>0.05), but the incidences of pancreatic fistula and delayed gastric emptying, postoperative drainage time, hospital stay, and mortality were all higher or longer in PPH group compared with non-PPH group (P<0.001). Of the 16 PPH patients, early haemorrhage occurred in 3 patients (including 2 patients with gastrointestinal haemorrhage and 1 patient with intra-abdominal haemorrhage) and delayed haemorrhage occurred in 13 patients (including 6 patients with gastrointestinal haemorrhage and 7 patients with intra-abdominal haemorrhage). All the 3 patients with early haemorrhage were cured by surgery. Of the 13 patients with delayed haemorrhage, 5 patients were cured by radiological intervention, 2 patients were cured by endoscopic hemostasis, and 3 patients were cured by conservative treatment, but 3 patients with sentinel bleeding died after interventional embolization+surgery. Conclusions The mortality of PPH is high. Surgery is optimal to early haemorrhage and radiological intervention is optimal to delayed haemorrhage, including embolization or covered stent implantation. The sentinel bleeding should be given great attention.
Objective To investigate the cl inical appl icabil ity and value of internal fixator for the reconstruction of lumbar isthmus in the treatment of lumbar vertebral spondylolysis and to lay a fundation for its cl inical appl ication. Methods Sixteen healthy goats weighing 22.65-31.22 kg were selected to establ ish the models of vertebral spondylolysis at L5, which thereafter were randomized into two groups (n=8): bone graft group in which 0.8-1.1 g fresh autogenous bone was transplanted into the isthmus spondylolysis area, and internal fixation with bone graft group in which internal fixator was installed before transplanting 0.8-1.1 g fresh autogenous bone into the isthmus spondylolysis area. All animals were killed 8 weeks after operation to receive imaging, topographic anatomy and histology detection. Meanwhile, biomechanics test was performed by using 5 donated vertebral body specimens (4 males and 1 female aged 35-51 years old). The left isthmus of L5 vertebra was transected to serve as lumbar vertebral spondylolysis model. A mini-displacement sensor was put at the transected ends of the isthmus. Then loading was conducted with a constant velocity of 2 mm/min by electronic omnipotent tester simulating the direction of fixation force of the internal fixator, and the deformation value of the transected ends was collected by a dynamic data collector and analyzer. The loading wascontinued until the vertebra specimens were damaged. The deformation of displacement sensor and the closure of transected ends of the lumbar isthmus were observed. Results All the goats behaved normally shortly after operation, and no nerve injury induced by operation and no wound infection occurred. Bilaterally obl ique X-ray films of lumbar vertebra and topographic anatomy 8 weeks after operation showed the fusion rate of the internal fixation and bone graft group and the bone graft group was 100% and 62.5%, respectively, indicating there was a significant difference (P lt; 0.05). Histology observation showed 3 goats in the bone graft group presented empty bone trabecula, empty bone lacuna and the disappearance of osteocytes at the transected ends of lumbar isthmus; while in the internal fixation and bone graft group, the bone trabecula grew into cancellous structures with hematopoietic and fatty bone marrow tissue inside, and parts of the bone trabecula had various degrees of mosaic-l ike pattern. During the upload, the biomechanics test and data processing results showed when the external load was 40 N, the deformation of displacement sensor was identified and the gap between the transected ends of lumbar isthmus started to close; then with the increase of external load, the displacement sensor tended to ascend in a l inearity manner; while when the external load was 212 N, the displacement sensor had no further deformation, the gap between the transected ends of lumbar isthmus wascompletely closed, and the pressor effect appeared. Conclusion The internal fixator for the reconstruction of lumbar isthmus has mechanical effects of stabil izing and elevating pressure with a high fusion rate.
