Objective:To summarize the clinical experience of surgical treatment abdominal gastrointestinal foreign body in children, thus to provide a theoretical basis for clinical decision-making.Methods:The clinical data, including age distribution, clinical manifestations, surgical treatment strategy and prognosis, from 60 children with abdominal gastrointestinal foreign body treated by operation in Children's hospital of Hu′nan Province from January 2015 to June 2020, were retrospectively analyzed. Among the 60 children, 38 males and 22 females, with a median age of 2.9 years. Observation data included the type and location of foreign bodies in the digestive tract, clinical manifestations and surgical methods, operation time, intraoperative blood loss, postoperative hospital stay. The following-up time was 6 months to 2 years by telephone or clinic. The short/long-term complications was observed.Results:Children under 3 years old accounted for 56.7%. Types of foreign bodies included magnetic foreign bodies, sharp objects[paper clips, nails, screws, fish bone and others, etc], crystal ball, jujube pit, gastric hair stone, batteries and badminton holder. The foreign bodies were mainly located in stomach and small intestine. Abdominal pain and vomiting were the most common symptoms. The patients of foreign body with long residence time had peritonitis such as fever and abdominal pain, among 21 cases were combined with gastrointestinal perforation. There were varieties kind of operaion methods, including gastrointestinal incision and foreign bodies removal( n=22), appendectomy and foreign bodies removal( n=7), repair of gastrointestinal perforation( n=6), intestinal resection and anastomosis( n=17), intestinal resection plus enterostomy( n=5)but whose fistula was closed after 3 months, lateral wall of rectum repair( n=3). Fifty-two patients underwent common open abdomen operation, 8 patients underwent laparoscopic operation. The operating time was(93.5±19.3) min. Intraoperative blood loss was(20.2±4.3) mL. The postoperative hospitalization was 13(5, 19) d. The postoperative complications occurred in 3 patients who were nonoperative treatment recovery. Conclusions:Magnetic foreign body, sharp foreign body, crystal ball, jujube nucleus and corrosive foreign body are the main causes of digestive tract obstruction and perforation in children. Individualized operation plan should be selected as soon as possible according to the number of foreign bodies, retention position and whether or not digestive tract perforation.

Objective To discuss the effect of a moving folding multifunction operating platform in operation room so as to solve time-consuming and efforts in the putting lithotomy position of repeating placement and removal surgery bed legs plate and supply the operating platform in the surgery of the upper limb, inva-sive puncture and anesthesia operation.Methods A moving folding multifunction operating platform was self-designed. A number of 160 cases undergoing operation in lithotomy position in the urology department from March to June 2016 were randomly divided into the experimental group (80 cases) and the control group (80 cases). The routine nursing method were carried out in patients in the control group, while adopted operating platform were used in patients in the experimental group. Time-consuming pre and post operation were investigated. Application effects of moving folding multifunction operating platform in 114 cases including the surgery of the upper limb, invasive puncture and anesthesia operation were evaluated.Results During continues lithotomy position surgery, time consuming of changing position and position placement in the experimental group were (209.41±33.36) s and (622.33±62.16) s respectively, while those in the control group were (665.83±90.92) s and (1118.33±88.86) s. The differences were statistically significant between two groups (t=16.324, 15.844;P<0.05). In one lithotomy position surgery, time consuming of position placement pre and post operation were reduced 44.03% (saved 8.16 minutes/surgery) compared to that in the control group. It alleviated 60 kg body burden of nurses. The safety and performance evaluation in the surgery of the upper limb, invasive puncture and anesthe-sia operation were in high levels with scores of (26.13±1.53) and (27.42±1.56) respectively.Conclusions The platform, which is practical and easy to use, contributes to meet the needs of a variety of technical operation in the operation room and helps optimizing procedure in transformation, reducing work load of nurse so as to im-prove efficiency and quality of work.

Objective:To explore the feasibility and effect of applying spherical fitting technology in CT three-dimensional reconstruction in preoperative planning of the resection range of Cam-type femoral acetabular impingement (FAI).Methods:46 Cam-type FAI patients who underwent arthroscopic femoroplasty in the Department of Sports Medicine in the Third Affiliated Hospital of Southern Medical University from July 2020 to June 2022 were enrolled in the spherical fitting group, including 26 females and 20 males, with an average age of 38.4±15.2 years (range of 24-53 years). The preoperative planning was performed using spherical fitting technology in CT three-dimensional reconstruction. Another 42 Cam-type FAI patients who underwent arthroscopic femoroplasty from July 2018 to June 2020 were enrolled in the observation group, including 25 females and 17 males, with an average age of 43.6±18.4 years (range 24-61 years). The preoperative planning was performed using CT three-dimensional reconstruction observation method. This study evaluated the impact of femoroplasty planned by spherical fitting technique on patients' prognosis though comparing the differences of postoperative α angle, femoral head-neck offset ratio, modified Harris hip score (mHHS), and visual analog score (VAS) at 3, 6, 9, and 12 months between two groups.Results:The average follow-up time was 11.8±0.6 months in spherical fitting group and 11.3±0.8 months in observation group. There was no significant difference regarding α angle, femoral head-neck offset ratio, mHHS, and VAS between two groups preoperatively ( P>0.05). The mHHS in two groups increased gradually, while VAS decreased sequentially at 3, 6, 9, and 12 months postoperatively. The postoperative mHHS and VAS were significantly better than those before surgery ( P<0.05). The mHHS was 83.2±14.8 vs. 70.5±11.2 in spherical fitting group and observation group at the followup of 9 months with significant difference ( t=4.471, P=0.007). It was 85.7±13.3 vs. 73.2±12.5 at the followup of 12 months with significant difference ( t=4.596, P=0.008). No significant difference was found in α angle, femoral head-neck offset ratio or mHHS at 3 and 6 months postoperatively ( P>0.05), and no significant difference was found in VAS at 3, 6, 9, and 12 months postoperatively between two groups. Conclusion:The spherical fitting technology in CT three-dimensional reconstruction could assist surgeons with planning of the resection range of Cam deformity preoperatively, and achieve a smooth progress of arthroscopic femoroplasty intraoperatively; after short term follow-up, we found that patients who underwent femoroplasty using this technology achieved satisfactory outcomes.

OBJECTIVE: To testify the spatial relationship between the subscapularis muscle splitting window and the axillary nerve in modified arthroscopic Latarjet procedure, which could provide anatomical basis for the modification of the subscapularis muscle splitting. METHODS: A total of 29 adult cadaveric shoulder specimens were dissected layer by layer, and the axillary nerve was finally confirmed to walk on the front surface of the subscapularis muscle. Keeping the shoulder joint in a neutral position, the Kirschner wire was passed through the subscapularis muscle from back to front at the 4 : 00 position of the right glenoid circle (7 : 00 position of the left glenoid circle), and the anterior exit point (point A, the point of splitting subscapularis muscle during Latarjet procedure) was recorded. The vertical and horizontal distances between point A and the axillary nerve were measured respectively. RESULTS: In the neutral position of the shoulder joint, the distance between the point A and the axillary nerve was 27.37 (19.80, 34.55) mm in the horizontal plane and 16.67 (12.85, 20.35) mm in the vertical plane. CONCLUSION In the neutral position of the shoulder joint, the possibility of axillary nerve injury will be relatively reduced when radiofrequency is taken from the 4 : 00 position of the right glenoid (7 : 00 position of the left glenoid circle), passing through the subscapularis muscle posteriorly and anteriorly and splitting outward.
