OBJECTIVE: To describe a novel arthroscopic technique of modified tri-anchor double-pulley suture-bridge in repairing medium-sized supraspinatus tendon tears and evaluate the early effectiveness. METHODS: Between June 2021 and January 2024, 26 patients with medium-sized supraspinatus tendon tears who underwent arthroscopic modified tri-anchor double-pulley suture-bridge repair and met the selective criteria were included. There were 11 males and 15 females with an average age of 61.4 years (range, 43-74 years). Five patients had a significant history of trauma, while the remaining 21 patients had no apparent cause. The time from symptom onset to hospitalization was 3-25 months (mean, 7.9 months). The effectiveness was evaluated during follow-up, including the scores of University of California at Los Angeles (UCLA), American Shoulder and Elbow Surgeons (ASES), visual analogue scale (VAS), the range of forward flexion, abduction, external rotation, and internal rotation, and patient's satisfaction. Either MRI or ultrasound examination were used to evaluate structural integrity of the tendon. RESULTS: The operation time was 65-110 minutes (mean, 81.8 minutes). All patients were followed up 12-43 months (mean, 23.0 months). At 3 and 12 months after operation, the shoulder range of flexion, abduction, external rotation, and internal rotation, and the scores of VAS, UCLA, and ASES significantly improved when compared with those before operation ( P<0.05). The improvement was further observed at 12 months compared to 3 months ( P<0.05). At last follow-up, 13 patients were very satisfied with the effectiveness, 11 patients were satisfied, 1 was relatively satisfied, and 1 was dissatisfied. During follow-up, 15 patients underwent imaging examination and imaging reexamination showed that the re-tear rate of tendon was 6.6%(1/15). The remaining 11 patients refused imaging examination. Complications included partial anchor withdrawal in 1 case, shoulder stiffness in 5 cases, and mild pain in shoulder joint in 2 cases in physical activity or heavy physical activity. CONCLUSION Arthroscopic modified tri-anchor double-pulley suture-bridge technique is a novel surgical technique that uses double-loaded suture anchors as medial- and lateral-row anchors. In repairing medium-sized supraspinatus tendon tears, 6 sets of double-pulley suture-bridges can be created from one medial-row anchor; knotless medial-row can reduce re-tear rate of the tendon; good early effectiveness is obtained.

Immune checkpoint inhibitors (ICIs) have been approved for the treatment of a variety of solid tumors and hematological malignancies. Adverse reactions caused by ICIs have been gradually focused on. Cytomegalovirus (CMV) gastritis after ICIs treatment is relatively rare. Here we reported a case of advanced lung adenocarcinoma who experienced recurrent upper abdominal pain and vomiting after Pembrolizumab treatment. CMV gastritis was diagnosed through gastroscopy. The patient's symptoms improved after antiviral treatment. During the treatment of ICIs, attention should be paid to the differential diagnosis of upper abdominal pain symptoms, and vigilance should be maintained against CMV gastritis. It is difficult to differentiate CMV gastritis and immune-related gastritis judging from symptoms, and gastroscopy is important for differential diagnosis.

Objective:To compare the clinical outcomes and costs in arthroscopic repair of small and medium-sized supraspinatu tendon tears between double-pulley suture-bridge (DPSB) and traditional suture bridge (SB).Methods:A retrospective study was conducted at Department of Joint Surgery, The Second Hospital Affiliated to Hengyang Medical School to analyze the data of 26 patients with small and medium-sized supraspinatus tendon tears who had been treated by SB repair from May 2018 to December 2020 (SB group) and those of 35 patients with small and medium-sized supraspinatus tendon tears who had been treated by DPSB repair from January 2021 to December 2022 (DPSB group). There were 61 patients in the 2 groups, including 44 males and 17 females, with an age of (59.1±7.5) years. The left shoulder was affected in 26 patients and the right shoulder in 35 patients. The tear size was small in 25 cases and medium in 36 ones. The total number of anchors used, total anchoring costs, and surgical time were recorded and compared between the 2 groups. Visual analogue scale (VAS), American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) score and shoulder range of motion were used to evaluate the clinical outcomes of the 2 groups before surgery and at the last follow-up. Comparisons were made within and between the 2 groups. Tendon integrity was assessed using MRI or ultrasound at 3, 6, 12 months or at the last follow-up.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). DPSB and SB groups were followed up for (28.1±3.5) and (27.1±1.8) months, respectively. There was no statistically significant difference between DPSB group and SB group in surgical time or total number of anchors ( P>0.05). The total costs of anchoring in DPSB group [(6,028.6±173.4) yuan] were significantly lower than those in SB group [(13,257.1±554.2) yuan] ( P<0.05). At the last follow-up, the anterior flexion, abduction, external rotation and internal rotation of the shoulder, as well as VAS pain score, ASES score and UCLA score, were significantly better in both DPSB group and SB group than their preoperative values ( P<0.05), but there were no statistically significant differences between DPSB group and SB group ( P>0.05). There was no significant difference either in tendon retear between DPSB group (2 cases) and SB group (1 case) ( P>0.05). No such complication as wound infection or nerve damage was found in either group. Conclusions:In arthroscopic repair of small and medium-sized supraspinatu tendon tears, both DPSB and SB techniques can achieve satisfactory and comparable clinical outcomes. However, DPSB leads to lower total costs of anchoring.

Objective:To analyze the characteristics of transabdominal bowel ultrasound (TBUS) in immune checkpoint inhibitor-related colitis (IRC) and their correlation with endoscopic manifestations.Methods:A cross-sectional study was conducted. Clinical data from 10 patients with IRC treated at Peking Union Medical College Hospital from January 2022 to January 2024 were collected. The ulcerative colitis endoscopic index of severity (UCEIS) and Limberg classification were used to assess the severity of colonoscopy and TBUS examinations, respectively. Kendall's tau-b method was applied for correlation analysis between UCEIS scores and Limberg classification.Results:All the 10 patients were male with a median age of 65 years (59-74 years). The majority had lung cancer (8 patients) and all were in advanced stages, with 6 patients in stage Ⅲ and 4 in stage Ⅳ. They all received anti-programmed death 1 (PD-1) /anti-programmed death ligand 1 (PD-L1) combined with chemotherapy, among whom 2 patients were combined with anti-angiogenic drug treatment. The median time from the first immunotherapy to the onset of IRC was 1.50 (0.25-12.00) months; the median time from IRC treatment to clinical symptom relief to G1 was 2.45 (0.50-8.00) weeks. Nine patients were in the active phase, mainly G3 (8 patients) ; 1 was in the remission phase after treatment. TBUS showed that among the 9 active IRC patients, the entire colon was mainly involved (7 patients), with combined small intestine involvement (3 patients) ; the main manifestations were thickening of the bowel wall, with the thickest bowel wall being 7.0 (5.0-8.0) mm, mainly located in the sigmoid colon (3 patients) and descending colon (3 patients) ; increased bowel wall blood flow signals (Limberg classification 2-4) occurred in 7 patients; 3 active patients had perienteric fat wrapping, and 2 had blurred bowel wall stratification. The Kendall's tau-b correlation coefficient r between the entire colon UCEIS scores and Limberg classification was 0.891 ( P = 0.003), and the Kendall's tau-b correlation coefficient r between the colon segment UCEIS scores and Limberg classification was 0.690 ( P < 0.001) . Conclusion:During the active phase, the left colon of IRC is more severe in TBUS, which mainly manifests as the thickening bowel wall and increased blood flow signals, and the TBUS has good correlation with colonoscopy evaluation.

Objective:To discuss the risk factors for postoperative venous thromboembolism (VTE) in patients undergoing pancreatic surgery.Methods:The clinical data of 488 patients who underwent pancreatectomy at the First Affiliated Hospital of Harbin Medical University from Jan 2016 to Sep 2024 was retrospectively analyzed.Results:One hundred and sixteen patients (23.8%) developed VTE after pancreatic surgery. Logistic analysis showed that advanced age, abdominal surgery history, high preoperative white blood cell count, high platelet lymphocyte ratio (PLR), distal pancreatectomy with splenectomy, open surgery, conversion to open surgery, and long surgery duration were risk factors.Nomogram prediction model based on the above risk factors was constructed and the area under the ROC curve was subsequently measured to be 0.781 (95% CI: 0.731-0.830). Conclusion:The prevention and control of VTE should be strengthened for patients undergoing pancreatic surgery with advanced age, abdominal surgery history, high preoperative white blood cell count, high PLR, distal pancreatectomy with splenectomy, open surgery, conversion to open surgery, and long surgery duration.
