Objective To observe the clinical effect of neuroendoscopic minimal invasive surgery in treating the patients with intraventricular hemorrhage cast.Methods The prospective non-randomized con-trolled study was adopted.Sixty-eight inpatients with intraventricular hematoma cast receiving surgical treat-ment in the neurosurgery department of this hospital from January 2020 to January 2023 were selected as the study subjects;thirty-four cases adopting neuroendoscopic minimal invasive surgery served as the observation group and 34 cases adopting lateral ventricle drilling drainage served as the control group;the surgical time,in-traoperative bleeding volume,hospitalization duration,ICU duration,clearance time of postoperative ventricle hematoma,postoperative hydrocephalus occurrence,occurrence rate of recurrent bleeding in operating area and postoperative complications occurrence rate were observed in the two groups.The levels of serum TNF-α,L-6,CRP,GFAP,S100-β and NSE before operation and on postoperative 7 d were detected;the GCS scores,BI,NIHSS scores before operation and on postoperative 14 d were observed;the GOS scores in postoperative 6 months were observed.Results The surgical time and intraoperative bleeding amount in the control group were significantly less than those in the observation group(P＜0.05);the hospitalization duration,ICU dura-tion,clearance time of postoperative ventricular hematoma and incidence rate of hydrocephalus in the observa-tion group were significantly short or less than those in the control group(P＜0.05);there was no statistical-ly significant difference in postoperative rebleeding incidence rate between the two groups(P＞0.05);the in-cidence rates of pulmonary infection,urinary tract infection,deep venous thrombosis and surgical site infection in the observation group were significantly less than those in the control group(P＜0.05);there was no sta-tistically significant difference in organ dysfunction incidence rate between the two groups(P＞0.05);the lev-els of postoperative TNF-α,L-6,CRP,GFAP,S100-β and NSE in the both groups were significantly decreased compared with those before operation(P＜0.05);the observation group was significantly lower than the con-trol group(P＜0.05);the GCS,BI and NIHSS scores on postoperative 14 d in the two groups were signifi-cantly improved compared with before operation(P＜0.05);the observation group was significantly better than the control group(P＜0.05);the GOS score at postoperative 6 months in the observation group was bet-ter than that in the control group(P＜0.05).Conclusion Neuroendoscopic minimally invasive surgery is ef-fective in treating intraventricular hemorrhage cast with low incidence rate of postoperative complications,which is worthy of clinical promotion.

OBJECTIVETo investigate the indication, timing and methods of surgery for acute necrotizing pancreatitis.

METHODSThere were 5 538 patients with acute pancreatitis (AP) were treated in the Union Hospital, Tongji Medical College from January 2005 to December 2014. Of all AP cases, 2 415 patients with acute necrotizing pancreatitis proved by computed tomography, and 732 patients underwent surgical treatment. Among 732 patients with surgical treatment, 439 (60.0%) were males and two hundreds and ninety-three (40.0%) were females. The median age was 45 years, ranging 20-76 years. Two hundreds and eighty-nine cases were treated with minimally invasive debridement and drainage and 684 cases were treated with open debridement.

RESULTSThe cure rate of minimally invasive operation was 16.6% (48/289). The rest of the 241 patients were treated furtherly with open necrosectomy. Among 684 patients with open surgery, 523 patients (76.5%) were infected, and the median time from the onset of symptom to first open operation was 46 d (range 19-205 d). There were 115 patients need to surgery again because of necrotic tissue residual and the reoperation rate was 16.81% (115/684), 684 patients were performed open surgery on average 1.26 times per person. The main postoperative complications were intra-abdominal hemorrhage (37 cases), upper digestive tract fistula (34 cases), colonic fistula (12 cases), gastrointestinal obstruction (29 cases) and pancreatic fistula (83 cases). The overall incidence of complications were 28.5% (195/684). Forty-nine cases died after surgery and the mortality rate was 6.7% (49/732).

CONCLUSIONRational surgical indications and timing of surgical intervention are the key to improve the efficacy of necrotizing pancreatitis, open debridement is still an effective method for necrotizing pancreatitis.
