ObjectiveTo evaluate the efficacy of XiaochengqiMixture (XM) on promoting healing of colonic stoma. MethodsForty Wistar rats were divided into two groups randomly after colonectomy: experimental group (n=20) and control group (n=20). In early postoperatively stage rats were given gastric administration of XM in the experimental group and pure water in the control group. On day 3, 7, and 14 after establishment of animal models, laparotomy was performed in two groups of rats, respectively. Anastomotic stoma and surrounding tissues were harvested to detect the context of hydroxyproline and collagen fiber proportion by Masson dying. ResultsOn day 3 after establishment of animal models, hyperplastic collagen with small fiber was observed while no fasciculus was found. Hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.05). On day 7 after operation, many fasciculuses were found in two groups of rats, hydroxyproline context and collagen fiber proportion of rats were higher in experimental group than those in control group (Plt;0.01). On day 14 after operation, fasciculuses became bigger and more regular in arrangement, but there was no significant difference between the two groups (Pgt;0.05). ConclusionXM is capable of promoting healing of colonic stoma and might prevent the occurrence of anastomotic fistula.
Objective To reconstruct the blood supply of hepatic artery of therecipient rat by a modified arterial “sleeve” anastomoses. Methods SD-SD and SD-Wistar rats liver transplantation were performed in 30 and 50 cases, respectively. The donor splenic artery, left gastric artery, right gastric artery and gastroduodenal artery were ligated, meanwhile the proper hepatic arteries were reserved. The celiac trunk of donors and the stump of right kidney artery of recipient were anastomosed by using 8-0 suture with “sleeve” technique. Results Themean time of artery anastomoses was 4.00±1.31 min.The rate of success was 96.3％. The longest survival time in the model SD-SD(29 survived) was more than 2months. In SD-Wistar(48 survived), acute rejectiion was observed 3-5 days after operation andthe mean survival time of rat was 9 d. Conclusion The modifiedarterial “sleeve” anastomoses is an effective method to reconstruct blood supply of hepatic artery of rat recipient in rat liver transplantation.
ObjectiveTo evaluate the value of real-time indocyanine green fluorescence imaging navigation (ICG-FIN) in laparoscopic rectal cancer surgery. MethodsThe patients who adopted ICG-FIN during laparoscopic rectal cancer surgery in the Department of Anorectal Surgery of Xuzhou Central Hospital from April 2022 to June 2023 according to the inclusion and exclusion criteria (ICG-FIN group) were collected, meanwhile matching (1∶1) of patients who did not adopt ICG-FIN during laparoscopic surgery from January 2021 to May 2022 (control group). The general data, surgical conditions, intraoperative and postoperative outcomes between the two groups were compared. ResultsThere were 62 patients in the ICG-FIN group and 62 patients in the control group. There were no statistical differences in the gender, age, body mass index, comorbidities, and so on between the two groups (P>0.05). The tumor localization, lymph node tracing, fluorescence imaging of the intended resection of intestinal tract and anastomotic site were observed in the ICG-FIN group. Seven patients (11.3%) had changed in the intended resection of intestinal anastomotic line during surgery, while there were no changes of the surgical plan in the control group. There were no statistical differences (P>0.05) in terms of surgical method, operative time, intraoperative bleeding, proportion of ileostomy, time of the first postoperative exhaust, postoperative hospital stay, and incidence of short-term complications between the two groups. Compared with the control group, the incidence of anastomotic leakage was lower (P=0.012), and the number of lymph nodes cleaned was more (P=0.016) in the ICG-FIN group. However, there was no statistical difference in the number of positive lymph nodes detected between the two groups (P=0.343). ConclusionsAccording to the results of this study, ICG-FIN is a reliable and effective method during laparoscopic rectal cancer surgery, which can accurately localize tumor, trace and guide lymph node dissection. Real-time evaluation of intestinal blood flow perfusion is of great practical value in reducing anastomotic leakage.
From the observation of 33 specimens of the lower extremities it was discovered that at a point where 15cm below the pubic tubercle, at the lateral or medial border of the sartorius muscle, the femoral artery gave rise a cutancous artery supplying the skin of the anteromiddle of the thigh. At the same area, the skin was innervated by the cutaneous branch of the femoral nerve. According to this anatomic peculiarity of the distribution of the artery and nerve, a skin flap having neurovascular bundle could be constructed from that area for distant transfer. From 1989, this technique had been done in 4 cases with satisfactory results. The related anatomy, operative design, surgical technique and the clinical results were detailed.
Objective
To investigate the clinical value of " O”continuous biliary-enteric anastomosis combined with percutaneous transhepatic cholangial drainage (PTCD) in pancreaticoduodenectomy (PD).
Methods
The clinical data of 35 patients with PD who were admitted to Xinyang Central Hospital from June 2015 to June 2017 were retrospectively analyzed.
Results
All patients completed the " O” continuous biliary-enteric anastomosis combined with PTCD without perioperative death. ① The preoperative indwelling time of PTCD tube was (13.24±3.39) d, total bilirubin (TBIL) was (363.67±12.26) μmol/L on admission and (155.59±17.63) μmol/L on preoperative after PTCD, respectively. ② The operative time was (231.46±18.69) min, the intraoperative blood loss was (158.30±31.33) mL, the diameter of the hepatic ductal segment was (1.3±0.2) cm, and the duration of the " O” continuous biliary-enteric anastomosis was (7.31±1.52) min. ③ After surgery, the indwelling time of PTCD tube was (8.13±1.49) d, the hospitalization time was (27.31±5.49) d. Biliary leakage occurred in 1 case, pancreatic fistula occurred in 5 cases (3 cases of biochemical sputum and 2 cases of B-stage pancreatic fistula), abdominal infection occurred in 2 cases, pneumonia occurred in 3 cases, wound infection occurred in 2 cases. No postoperative biliary-enteric anastomosis stenosis, biliary tract infection, and intra-abdominal hemorrhage occurred. There was no laparotomy patients in this group and all patients were discharged. ④ All patients were followed-up for 180 days after surgery. No death, bile leakage, biliary-enteric anastomotic stenosis, biliary tract infection, pancreatic fistula, gastro-intestinal leakage, and abdominal infection occurred. One case of delayed gastric emptying and 2 cases of alkaline reflux gastritis were cured after outpatient treatment.
Conclusions
The preoperative PTCD can improve the preoperative liver function and increase the security of PD. " O” continuous biliary-enteric anastomosis is simple, safe, feasible, and has the function of preventing biliary-enteric anastomosis stenosis. For severe jaundice patients with blood TBIL >170 μmol/L, the " O” continuous biliary-enteric anastomosis combined with PTCD is an alternative surgical procedure for PD.

The transplants were all survived. The follow-up through 5 months, a comparatively good function and appearance were achieved.The applied anatomy, the surgical technique and the matters needing attention were detailed.
Objective To study and compare the effect of end-to-end and end-to-side neurorrhaphy between the reci pient’s musculocutaneous nerve and the donor’s ulnar nerve, and to observe the regeneration of peri pheral nerve and muscle refection. Methods Sixty male SD rats (weighing 200-250 g) were randomized into 2 groups (n=30 per group), and made the musculocutaneous nerve injury model. In group A, the donor’s nerve was transected for end-to-end neurorrhaphy.In group B, an epineurial window was exposed and the distal end of the muscle branch of musculocutaneous nerve was sutured to the side of the ulnar nerve. Electromyography was performed, biceps wet weight ratio, muscle fiber cross-sectional area, and count of myel inated nerve fiber (CMF) were measured at 4 and 12 weeks postoperatively. The behavior changes of the rats were observed. Results At 4 weeks, the nerve conduction velocity (NCV) and the latency ampl itude (AMP) of group A were significantly higher than those of group B (P lt; 0.05); at 12 weeks, there was no significant difference in the NCV and AMP between groups A and B (P gt; 0.05). At 4 and 8 weeks, there was no significant difference in biceps wet weight ratio and muscle fiber cross-sectional area between groups A and B (P gt; 0.05). At 4 weeks, the CMF was 230.15 ± 60.25 in group A and 160.73 ± 48.77 in group B, showing significant difference (P lt; 0.05); at 12 weeks, it was 380.26 ± 10.01 in group A and 355.63 ± 28.51 in group B, showing no significant difference (P gt; 0.05). Conclusion Both end-to-end and end-to-side neurorrhaphy have consistent long-term effect in repair of brachial plexus upper trunk injury.
