Objective To report a new approach of splenic hilar lymph nodes dissection in radical gastrectomy for gastric cancer. Methods 193 cases of gastric cancer patient receiving radical resection of gastric cancer between May 2008 and October 2008 were studied. The tail and body of spleen and pancreas were thoroughly freed with retroperitoneal way retrogressively and extruded out of abdominal cavity in 80 cases. The other 113 cases received operation with routine way. Results In 80 cases who received operation with retroperitoneal approach retrogressively, the total splenic hilar lymph nodes were 519, the positive ones were 65, the positive rate was 12.5 %; In the other 113 cases the total splenic hilar lymph nodes were 565, the positive ones were 58, the positive rate was 10.3 %. The positive rate had statistic significance between these two groups. Conclusion Extruded splenic hilar lymph nodes dissection with retroperitoneal approach retrogressively is safe and has the same effect with splenectomy in gastric cancer operation.

Objective To investigate the surgical management of huge pelvic tumor.Methods The clinical data of 56 patients with huge pelvic tumor who were admitted to the Cancer Hospital of Henan Province from February 2005 to January 2012 were retrospectively analyzed.Tumor resectability was assessed via enhanced computed tomography or three-dimensional reconstruction,and the tumors were freed and resected by combination of muliiple surgical approaches.All the patients were followed up via telephone or re-examination at the out-patient department to learn the recurrence and metastasis of tumor.The survival rate was calculated using the life table.Results Fifty patients received preoperative computed tomography examination,and the imaging data of 6 patients were three-dimensionally reconstructed.Preoperative evaluation showed that 49 patients needed combined multivisceral resection,5 needed tumor resection,and the tumors of 2 patients were unresectable.Fourteen patients were diagnosed preoperatively,and 8 patients were diagnosed by intraoperative rapid frozen section examination,and the rest 34 patients were diagnosed by postoperative pathological examination.The surgical approaches including anterior median sacral approach combined with transperineal coccyx anterior approach (21 patients),anterior median sacral approach (11 patients),obturator approach (8 patients),retropubic approach (8 patients) and obturator approach combined with transperineal approach of coccyx (8 patients).Tumor and rectum resection was carried out on 18 patients,tumor and partial bladder resection on 12 patients,tumor,uterus and ovariectomization on 12 patients,tumor,part of the small intestine and colorectal resection on 10 patients,tumor and total pelvic exenteration on 4 patients.In all the 56 patients,53 achieved R0 resection,2 cases reached naked eye clean,1 case had residual tumor.The mean operation time was 100 minutes.Fifty patients recovered uneventfully.Six patients had postoperative complications,including 3 patients with intestinal obstruction (2 patients were cured by conservative treatment,and 1 patient was cured by surgery),2 patients with pelvic infection and 1 patient with colostomy hernia,and they were cured by drainage and nutritional support.One patient died of postoperative myocardial infarction.The results of postoperative pathologic study showed that 25 patients were with adenocarcinoma,16 with sarcoma and 15 with gastrointestinal stromal tumor.Forty-seven patients were followup to December 2012,and the 5-year survival rate was 26.7％ for patients with adenocarcinoma,18.9％ for patients with sarcoma,and 52.6％ for patients with gastrointestinal stromal tumor.Conclusion Preoperative assessment of resectability of huge pelvic tumor can reduce unnecessary laparotomy and improve the safety of operation.

Objective To explore the relations between the post pancreatoduodenectomy pancreatic anastomotic hemorrhage and the length of pancreatic duct endoprosthesis placed in the jejunum.Methods From August 2006 to August 2011,63 patients underwent pancreaticoduodenectomy with the adopted child method for digestive tract reconstruction,while pancreaticojejunostomy reconstruction was divided into A,B,C groups.There were 22 cases in A group,and patients underwent pancreaticojejunostomy with anastomosis of the pancreatic stump into the jejunum strapping method,the length of pancreatic duct endoprosthesis placed in the jejunum was 15 cm; there were 21 cases in B group,and patients received the same operation as patients in group A,but the length of pancreatic duct endoprosthesis placed in the jejunum was 5 cm; there were 20 cases in C group,and patients received pancreatic stump and jejunal mucosa anastomosis,the length of pancreatic duct endoprosthesis placed in the jejunum was 5 cm.Results In group A,two cases (9.1％) of pancreatic anastomotic hemorrhage occurred,and patients were cured by conservative treatment.In group B,eight cases (38.1％) of pancreatic anastomotic hemorrhage occurred,and two cases died of gastrointestinal bleeding; 3 cases received surgical operation to stop bleeding,and 3 patients were cured by conservative treatment.There was no anastomotic hemorrhage occurred in group C.The bleeding times of group A and group B were about 15 days after surgery,the difference of incidence of anastomotic bleeding between the two groups was statistically significant (x2 =9.428,P =0.009).Conclusions Post pancreaticojejunostomy anastomotic hemorrhage is associated with short length of pancreatic duct endoprosthesis placed in the jejunum.

Objective To investigate the clinical effects of pedicled omentum covering the intestinal anastomotic stoma in preventing anastomotic fistula.Methods The clinical data of 133 patients with high risk of intestinal anastomotic stoma who were admitted to the Henan Tumor Hospital from May 2009 to May 2012 were retrospectively analyzed.All patients were divided into the improvement group (69 patients) and the control group (64 patients) according to whether the anastomotic stoma was covered by pedicled omentum.All the operations were done by the surgeons in the same group,and the intestinal reconstruction was done by the equipment produced by the same company.All the patients with intestinal tumors received radical resection.The clinical data of the patients in the 2 groups were reviewed and the therapeutic effects of the 2 approaches were compared.All data were analyzed using the chi-square test.Results Three (4.3％) patients had intestinal fistula in the improvement group,including 1 had small bowel anastomotic fistula,1 had small bowel and colonic anastomotic fistula,1 had colonic anastomotic fistula.Eight (12.5％) patients in the control group had intestinal anastomotic fistula,including 1 had duodenal anastomotic fistula,2 had small bowel anastomotic fistula,2 had small bowel and colonic anastomotic fistula,and 3 had colonic anastomotic fistula.There was a significant difference in the incidence of anastomotic fistula between the 2 groups (x2 =5.483,P ＜ 0.05).The highest body temperatures of the 3 patients in the improvement group were under 38.2 ℃,and the mean white blood cell count was 8.4 × 109/L;no peritonitis was detected; turbid drainage was observed in the peritoneal tube around the anastomotic stoma.The results of computed tomography showed local inflammation.The highest body temperatures of the 8 patients in the control group were above 38.5 ℃,and the mean white blood cell count was 14.4 × 109/L; obvious pressing pain and rebound tenderness were detected; intestinal contents were observed in the peritoneal drainage tube.The 3 patients in the improvement group were cured by symptomatic treatment.Of the 8 patients in the control group,7 received two-stage debridement,and 1 received jejunostomy and 3 received ileostomy.The condition of the 7 patients was recovered after operation,and reversion of the ileum at postoperative month 4.One patient died of multiple organs dysfunction syndrome and systemic inflammatory response syndrome.Conclusion Intestinal anastomotic stoma covered by pedicled omentum could effectively decrease the incidence of anastomotic fistula and alleviate systemic inflammatory response syndrome caused by anastomotic fistula.

Objective To explore the safety and feasibility of operation procedure improvement and process optimization for pancreatoduodenectomy.Methods The effect of the duation time of opertion and postoperative complications of operation procedure improvement and process optimization for pancreatoduodenectomy in 98 patients in the Tumour Hospital Affiliated to Zhengzhou University from August 2008 to May 2015 were retrospective analyzed.Results The duation time of opertion was 145-205 min,average time was 175 min.There were 5 cases (5.1％) of bile leakage,6 case (6.12％) of pancreatic fistula and 4 cases (4.08％) of hemorrhage,and laparotomy revealed that one of them with pancreas-intestinal anastomotic hemorrhage,the haemorrhage stop after sufficient drainage,but due to infection,organ failure,this case was dead half a year after the operation.The remaining patients recovered uneventfully through open drainage,partial flush,somatostatin application,and other conservative treatment.Conclusion The improved pancreatoduodenectomy can shorten operation time and reduce operation complication,is a safe and feasible method,and worthy of clinical popularization.

Objective To investigate application of modified abdominal closure technique by an all layer in ventro-pelvic part operation and evaluate its value and significance. Methods 3200 cases with ventre-pelvic part operation between May 2002 and Aug 2007, were subjected to single layer closure with non absorbable suture material. The clinic data and some results of follow-up were retrospectively analyzed. Results Operative incisions of 1780 (55.6%) cases were in epigastric zone and their rate of primary healing was 98.5%, others (44.3%) in hypogastric zone (including pelvic cavity) and rate of primary healing was 98.2% (P>0.05). Rate of primary healing in older age-group was 97.9% and control group 98.8%, and primary healing of group diabetes 97.4%, control group 98.2% (P > 0.05). Average time of abdmenal closure was only 11±4 min. Primary complications included dehiscence of wound (0.5%), infection (1.4%) and incisional hernia (0.2%). Follow-up (66%) was performed at 30 days, 3 and 6 months, and at 1, 2 and 3 years. Conclusion It is concluded that closure of an abdominal incision can be effected by a multifilament interrupted absorbable sutures without an increased risk of wound dehiscence or incisional hernia, meanwhile economic and fast. It is the optimal method of abdominal closure and can be generalized.

Objective To study the trans-bladder operative approach in resection of the complicated pelvic tumors with bladder invasion.Methods Twelve patients with complicated pelvic tumors were analyzed from Oct.2007 to Oct.2010.There were 8 males and 4 females.Patient's age was ranging from 35 to 65 years.There were 3 patients with tumor diameter from 10 to 16 cm and 9 patients with tumor diameter greater than 16 cm.All the tumors were located in the pelvic and the stage of all tumors was T4N0M0.The technology of trans-bladder to approach the lower edge of the pelvic tumor and then retrograde up to remove the tumor out of the presacral tissue,pelvic wall,and pelvic organ was applied.The length of hospital stay,operative time,blood loss,death during peri-operative period and the post-operative survival were analyzed retrospectively.Results The median operative time was 126 (110-150) min.The median blood loss was 521 (300-1200) ml.The median hospital stay was 22 (14-28) d.No patient died after surgery.Ten patients were followed up for 6 to 48 months.Three cases died of metastasis or recurrence.Conclusion With the trans-bladder operative approach,the resection of pelvic retroperitoneal tumors is effective and safe.

Objective To investigate the application value of the curved cutter stapler device combined with trans-orally inserted anvil (OrVil) in the radical resection of Siewert type Ⅱ adenocarcinoma of the esophagogastric junction (AEG).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 206 patients with Siewert type Ⅱ AEG who were admitted to the Henan Tumor Hospital between March 2011 and March 2016 were collected.All the 206 patients underwent radical resection and 3-step clock wise total gastrectomy + D2 lymph node dissection.Observation indicators:(1) surgery and postoperative recovery situations:surgical approach,overall operation time,hammer anvil placing time,esophagojejunal anastomosis time,volume of intraoperative blood loss,number of lymph node dissected,time to anal exsufflation,postoperative complications and duration of postoperative hospital stay;(2) postoperative pathological examination and chemotherapy;(3) follow-up and survival situations.Follow-up using telephone interview and outpatient examination was performed to detect tumor-free survival of patients up to April 2016.Measurement data with normal distribution were represented as x±s.The survival rate was calculated by the Kaplan-Meier method.Results (1) Surgery and postoperative recovery situations:all the 206 patients received successful operations,including 85 with abdominal operation,50 with abdominal incision through the diaphragmatic muscle into thoracic surgery and 71 with thoracic-abdominal surgery.Overall operation time,hammer anvil placing time,esophagojejunal anastomosis time,volume of intraoperative blood loss,number of lymph node dissected,time to anal exsufflation and duration of hospital stay were (113.7± 15.4)minutes,(3.5± 1.2)minutes,(10.4±2.9)minutes,(128±25) mL,32± 6,(2.4 ± 0.9) days and (12.3 ± 1.9) days,respectively.Of 206 patients,15 with postoperative complications were cured by conservative treatment,including 6 with implicit anastomotic fistula,3 with dominant anastomotic fistula,2 with pancreatic leakage,2 with intestinal obstruction,1 with anastomotic stenosis and 1 with thoracic and abdominal infection.There was no reoperation due to perioperative complications.(2) Postoperative pathological examination and chemotherapy:postoperative pathological results showed that distance from resection margin of the esophagus to tumor was (5.2±0.4) cm,without cancer cells in the resection margin.Among 206 patients,171 received postoperative chemotherapy by S1 single agent combined with oxaliplatin for 6-8 cycles or oral S1 single agent for 1 year.(3) Follow-up and survival situations:206 patients were followed up for (2.7± 0.3)years,with a tumor-free 3-year survival rate of 58％.During the follow-up,there was no recurrent anastomotic tumor.Conclusion The curved cutter stapler device combined with OrVil in the radical resection of Siewert type Ⅱ AEG can simplify the difficulty of esophagojejunal anastomosis and guarantee the safe resection margin of the lower esophagus.
