[Value of ultrasonography in diagnosis and classification of Masson's tumor].

A retrospective analysis was performed on 11 cases of Masson's tumor admitted to Liaocheng People's Hospital from January 2010 to July 2021. Among them, there were 4 males and 7 females, aged from 14 to 62 years, with a medical history of 1 to 24 months. All of the patients complained of touching the mass under the skin. In this group, 9 cases were pure form, 1 case was mixed form and 1 case was extravascular form. Ultrasound imaging can reflect the characteristics of Masson's tumor to a certain extent, which has a certain value in the diagnosis, classification and differential diagnosis.

[Preliminary efficacy analysis of Cheng's Giraffe reconstruction after proximal gastrectomy in adenocarcinoma of esophagogastric junction].

Objective: To investigate the safety and feasibility of proximal partial gastrectomy with Cheng's Giraffe esophagogastric reconstruction for the treatment of early Siewert II adenocarcinoma of esophagogastric junction (AEG). Methods: Indication of Cheng's Giraffe esophagogastric reconstruction: (1) Siewert II AEG or Siewert III AEG with diameter < 4 cm; (2) preoperative staging as cT1-2N0M0. A descriptive case series study was carried out. Clinical data of 34 patients with Siewert II AEG undergoing proximal partial gastrectomy and Cheng's Giraffe esophagogastric reconstruction at Department of Abdominal Surgery of Zhejiang Cancer Hospital and Department of Gastrointestinal Surgery, The First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from February to July 2018 were retrospectively collected and analyzed, including 14 cases in IA stage, 11 cases in IIA stage and 8 cases in IIB stage. Brief procedure of Cheng's Giraffe esophagogastric reconstruction was as follows: Firstly, 12 cm long tubular stomach was formed by longitudinal incision 4 cm away from the great curvature of the stomach. Secondly, the gastric fundus and His angle were formed. Finally, the distance from His angle to esophagal-tubular gastric anastomosis should be more than 5 cm. The reflux disease questionare (RDQ) scores, radionuclide gastric emptying scintigraphy, and 24-hour multichannel intraluminal (MII)-pH monitoring technology were used to evaluate postoperative gastric emptying and gastroesophageal reflux. Result: All 34 patients successfully completed proximal partial gastrectomy with Cheng's Giraffe esophagogastric reconstruction, including 13 cases by open surgery and 21 cases by laparoscopic surgery. The operation time was (144.6±39.8) minutes, the blood loss during operation was (35.4±17.2) ml. No laparoscopic case was converted to open surgery and no postoperative complication was observed. The postoperative hospital stay was (8.4±2.5) days. The postoperative RDQ score was 4.4±3.1 one month after operation, and 3.3±2.5 six months after operation. Gastric-half emptying time was (67.0±21.5) minutes, and the residual ratio was (52.2±7.7)% in 1 hour, (36.4±3.1)% in 2 hours and (28.8±3.6)% in 3 hours at postoperative 1-month. The 24-hour MII-pH monitoring at postoperative 2-month revealed the frequency of acid reflux was (12.6±7.9) times, frequency of non-acid reflux was (19.6±9.7) times, DeMeester score was 5.8±2.9. Conclusion: Cheng's Giraffe esophagogastric reconstruction is safe and feasible in the treatment of Siewert type II AEG, and has good dynamic and anti-reflux effects.

PFNA vs. DHS helical blade for elderly patients with osteoporotic femoral intertrochanteric fractures.

OBJECTIVE: This study sought to compare the effects of proximal femoral nail anti-rotation (PFNA) and dynamic hip screw (DHS) helical blade treatments in patients with osteoporotic femoral intertrochanteric fractures. PATIENTS AND METHODS: Eighty elderly osteoporosis patients with femoral intertrochanteric fracture complications admitted to the hospital between January 2013 and December 2014 were selected and divided into control (n=40) and observation (n=40) groups. The control group received DHS internal fixation while the observation group received PFNA treatment. Patients were followed up for 18 months, during which pre- and post-operative duration, Harris hip joint function scale, pain, bone mineral density and calcitonin level, 10 meter walking speed, five-fold-sit-to-stand test time, fracture healing and weight bearing time, and related complications were compared between groups. RESULTS: Operational duration, hemorrhaging and drainage volume were all decreased in the observational group relative to the control group (p<0.05). Pre-operative Harris hip joint function scale scores were not significantly different between the two groups, but were superior in the observation group post-operation (p<0.05). A similar trend was observed for pain degree, bone mineral density and calcitonin levels, 10-meter walking speed, five-fold-sit-to-stand test time, and fracture and weight healing time (p<0.05). Complication incidence, such as coxa vara, loose nail, bone nonunion, delayed union of fracture, femoral head necrosis and deep venous thrombosis, etc., in the observation group was significantly lower than in the control group (p<0.05). CONCLUSIONS: PFNA is characterized by minimal invasiveness, shorter time of operation, and accelerated post-operative recovery during the treatment of osteoporotic intertrochanteric fractures, and effectively improved patient bone density post-operatively, thus further promoting joint function recovery and reducing complication incidence.
