Objective To investigate the intervention ways of endoscopes in the treatment of esophagus stenosis due to carcinoma of esophagus and improvement of quality. Method 11 cases of advanced carcinoma of esophagus were included in this study. Operation and chemical therapy were unavailable for these patients. Memory trestle with membrane and made of alloy of Nickel－ titanium was inserted under intervention of endoscope. Trestle was posed in stenosis part of esophagus under direction of X－ ray. Trestle could be dilated 3－ 7 days after operation due to its reaction characteristics to temperature. So, redilated therapy was unnecessary. Trestle could reconstruct swallowing tract and made feeding through mouth become available during limited survival time.Results All trestles were successfully inserted.Half－ fluid feeding was available after operation. Obstruction was removed in all patients(100％ ).Conclusion Method described in this study was safe and effective .Effective swallowing tracts were reconstructed in all patients after trestle was planted and quality of life and survival time were both improved.

OBJECTIVETo retrospectively investigate the effectiveness of sphenzygomatic suture as a guide in the reduction of zygomatic complex fracture.

METHODS55 cases of zygomatic complex fracture classified according to Zingg classification were treated, sphenozygomatic suture in group 1 (n = 36) was reduced first, then the other fracture line was reduced, in group 2 (n = 19), malar bone was reduced according to superficial fracture line. Patients were followed up for 4 weeks to 3 months, aesthetic result and X-ray symmetry were observed.

RESULTSAll patients in group 1 were restored with satisfactory facial contour, 35 cases got precise reduction, 5 cases in group 2 were asymmetry.

CONCLUSIONDuring open reduction of complex zygomatic fracture, sphenozygomatic suture should be reduced at first as a guide, so as to get precise zygomatic complex reconstruction and normal aesthetic outcome.

Objective:To compare the clinical effectiveness of laparoscopic cholecystectomy (LC)+ laparoscopic choledocholithotomy (LCBDE)+ one-stage suture and primary choledocholithotomy with endoscopic retrograde cholangiopancreatography (ERCP)+ endoscopic duodenal sphincterotomy (EST)+ nasobiliary drainage (ENBD)+ LC in the treatment of choledocholithiasis complicated with gallbladder stones.Methods:A total of 200 patients with choledocholithiasis complicated with gallbladder stones admitted to the General Surgery Department of Shanxi Bethune Hospital from June 2015 to February 2021 were collected, and patients were divided into LC+ LCBDE+ one-stage suture (one-stage suture group, n=130) and ERCP+ EST+ ENBD+ LC (endoscopic surgery group, n=70) according to different treatments. The amount of intraoperative blood loss, operation time, postoperative feeding time, postoperative incidence of pancreatitis, cholangitis and other complications (biliary leakage, abdominal bleeding, wound infection), hospitalization costs, postoperative hospital stay, etc were compared between two groups. Results:The postoperative incidence of pancreatitis in the one-stage suture group (0.7% vs 5.7%) and the hospitalization cost [(2.74±0.39) ten thousand yuan vs (3.86±0.63) ten thousand yuan] were significantly lower than those in the endoscopic surgery group. The operation time [(103.21±9.36) min vs (88.18±7.20)min] was significantly longer than that of the endoscopic surgery group, and postoperative feeding time [(3.3±0.3)d vs (2.2±0.8)d] were significantly later than the endoscopic surgery group ( P<0.05). The amount of intraoperative blood loss [(36.0±3.0)ml vs (37.3±2.7)ml], the incidence of postoperative cholangitis (1.5% vs 2.9%) and other complications [biliary leakage (2.3% vs 1.4%), abdominal bleeding (1.5% vs 4.3%), wound infection(0 vs 0)], postoperative hospital stay [(6.8±1.3)d vs (7.1)d] had no significant differences between the two group. Conclusions:The two minimally invasive methods for the treatment of choledocholithiasis complicated with gallbladder stones had good efficacy, but LC+ LCBDE+ one-stage suture can retain the sphincter function of Oddis, maintain the normal anatomy and physiology of the biliary tract, reduce the incidence of related complications, and contribute to the recovery of patients, with high safety, effectiveness and feasibility.

Objective:To investigate the safety and efficacy of early oral feeding in the treatment of mild acute pancreatitis (MAP).Methods:Data of 100 MAP patients from April 2015 to June 2018 admitted in Department of General Surgery in Shanxi Bethune Hospital were collected. According to the time of food intake through the mouth, the patients were divided into early oral feeding group (food intake started when the symptoms of abdominal pain and abdominal distension were alleviated with gastrointestinal functional recovery, but serum amylase and lipase did not decrease to a level below 2 times of normal upper limits) and traditional oral feeding group (food intake started when the symptoms of abdominal pain and abdominal distension were alleviated with gastrointestinal functional recovery, but serum amylase and lipase decreased to a level below 2 times of normal upper limits), with 50 cases in each group. The incidence of abdominal pain or bloating, serum amylase, CRP, organ dysfunction, morbidity and mortality, and median length of hospital stay after eating were compared between the two groups.Results:There were no statistically significant differences on gender, age, etiology, abdominal pain and distension, increased serum amylase, increased blood CRP, and number of organ dysfunction cases between two groups, and there were no deaths in either group. However, the feeding time and length of hospital stay in the early oral feeding group were significantly shorter than those in the traditional oral feeding group, and the differences were statistically significant [(3.00±0.18)d versus (4.84±0.27)d, (8.24±0.33) D versus (9.00±0.26)d, both P<0.05]. Conclusions:Early oral feeding in MAP patients did not aggravate the disease, but helps to correct the nutritional status of the patients, with higher safety and effectiveness.

Objective To evaluate open reduction and internal fixation (ORIF) combined with Ilizarov joint distraction in the treatment of comminuted talar body fractures.Methods Between July 2010 and May 2016,16 patients with comminuted talar body fracture underwent ORIF followed by ankle joint distraction by Ilizarov external fixator at our department.They were 9 males and 7 females,aged from 17 to 56 years (average,35.6 years).Radiological assessments were conducted by plain radiographs and computed tomography (CT) scans pre-and post-operatively.Clinical outcomes were evaluated according to visual analogue scale (VAS),American Orthopedic Foot and Ankle Society (AOFAS) hindfoot score,the short form (SF)-36 health survey scores and patients' satisfaction.Results Two patients were lost to follow-up.The remaining 14 patients were followed up for an average duration of 33.3 months (from 13 to 52 months).All the fractures united.Superficial wound infection occurred in one case.Eight patients developed post-traumatic osteoarthris;4 patients presented with avascular necrosis.At final follow-ups,the AOFAS scores ranged from 30 to 97 points (mean,69.8 points),the VAS scores from 0 to 6 points (mean,2.5 points),the physical component summary in SF-36 from 18.0 to 55 points (mean,41.7 points),and the mental component summary from 40 to 70 points (mean,54.1 points).Two patients reported strong satisfaction,5 satisfaction,4 moderate satisfaction,and 3 dissatisfaction.Conclusion For comminuted talar body fractures,ORIF combined with Ilizarov joint distraction is a new and effective treatment which can not only provide adequate fixation strength but also reduce the incidence of post-traumatic osteoarthris or avascular necrosis.

Objective To analyze the clinical outcomes of a standard protocol of open reduction and internal fixation using a variable angle foot plate for a consecutive series of patients with acute Lisfranc joint injury.Methods This study retrospectively evaluated the clinical outcomes of 11 Chinese patients(13 feet) with acute Lisfranc joint injury who had been treated by open reduction and internal fixation with a variable angle foot plate from December 2016 to June 2017 at Department of Orthopaedics,West China Hospital.They were 8 men(10 feet) and 3 women(3 feet),aged from 19 to 57 years(average,36.4 years).Of them,10 were complicated with fracture of metatarsus,6 with cuneiform fracture and/or dislocation,4 with cuboid fracture,and one with cuboid fracture.According to the Myerson classification for Lisfranc fracture-dislocations,one case(one foot) belonged to type A,2(2 feet) to type Bl,5(6 feet) to type B2,2(3 feet) to type Cl and one(one foot) to type C2.The outcomes were evaluated using the visual analogue scale(VAS) and the midfoot scores of American Orthopedic Foot and Ankle Society(AOFAS).Results This cohort was followed up for 18 to 24 months(average,22 months).Their VAS scores were decreased significantly from preoperative 7.3±1.2(from 6 to 9) to postoperative 1.2±0.2(from 0 to 2)(P<0.05);their AOFAS midfoot scores were increased significantly from preoperative 0 to postoperative 84.6±4.6(P<0.05) Anatomic reduction was obtained in all the patients and all the fractures united successfully without any delayed union or nonunion.Superficial necrosis of the wound edge occurred in 2 cases without deep infection;skin anesthesia occurred in 2 and skin hypesthesia in 4,indicating a lesion of the superficial peroneal nerve.Conclusion Fixation of acute Lisfranc joint injury with a variable angle foot plate can lead to rigid stability,precise reduction and satisfactory short-term clinical outcomes.
