OBJECTIVETo explore the safety and feasibility of cervical triangulating stapled anastomosis(TSA) for esophagogastric anastomosis(EGA) after minimally invasive esophagectomy (MIE).
METHODSClinical data of 137 patients undergoing MIE for esophageal cancer(EC) in our department from January 2013 to March 2014 using end to side circular stapled anastomosis (CSA, 60 cases) or end-to-end triangulating stapled anastomosis (TSA, 77 cases) in the neck were retrospectively analyzed. The short-term outcomes between the two groups were evaluated and compared.
RESULTSCervical anastomotic leakage occurred in 3 patients(3.9%) of TSA group, but in six(10.0%) of CSA group (P=0.152). The incidence of anastomotic stenosis was 1.3%(1/77) and 15.0%(9/60) in TSA and CSA group respectively(P=0.002). The median hospital stay and perioperative mortality were not significantly different between the two groups as well as postoperative respiratory and cardiovascular complications.
CONCLUSIONSTSA is a safely and effectively alternative method for EGA with lower incidence of postoperative gastrointestinal complications, especially in anastomotic stricture.

The incidence of adenocarcinoma of esophagogastic junction (AEG) has been rising in recent years. Despite that multimodality therapy including surgery advances tremendously, the 5-year survival rate of AEG patients remains poor. Due to the particularity of anatomy and pathology of AEG, controversies persist with regard to staging, surgical approaches, scope of lymph node dissection, extent of gastrectomy as well as the reconstruction of digestive tract. High level of evidence based on clinical trials is still lacking. Here, in light of recent progress in surgical treatment of AEG, the authors investigate the related strategies of surgical treatment of AEG from the perspective of thoracic surgeon, in order to provide references to surgeons.

Objective:To investigate the short-term clinical efficacy of laparo-gastroscopic esophagectomy (LGE).Methods:The retrospective and descriptive study was conducted. The clini-copathological data of 11 patients with esophageal cancer who underwent LGE in the Zhongshan Hospital of Fudan University from June 2020 to October 2021 were collected. There were 8 males and 3 females, aged (68±4)years. Sorted by operation time, the sentinel lymph nodes navigation (SLN) was performed since the sixth patient in the cohort, and abdominal surgery and neck surgery were performed simultaneously to complete LGE. Observation indicators: (1) surgical situations; (2) postoperative situations; (3) follow-up. Follow-up was conducted using outpatient examination or telephone interview to detect death of patients during postoperative 30 days. Patients were followed up during postoperative 30 days. Measurement data with normal distribution were represented as Mean± SD, and count data were described as absolute numbers. Results:(1) Surgical situations. Of the 11 patients, 5 cases received SLN with satisfactory visualization, 6 cases did not receive SLN, 1 case terminated the operation as sentinel lymph nodes biopsy showing positive results and the rest of 10 cases completed LGE successfully without conversion to thoracotomy. The operation time and tumor diameter of the 10 patients completing LGE was (204±27)minutes and (2.5±1.0)cm, respec-tively. (2) Postoperative situations. Of the 10 patients completing LGE, 2 cases had pulmonary complications after surgery and recovered well with symptomatic treatment, and none of patient had anastomotic leakage or other serious complication. Results of postoperative histopathological examination showed squamous cell carcinoma in the 10 patients completing LGE. Nine patients were classified as T1b?3N0M0 stage and 1 patient was classified as T1bN1M0 stage. Ten patients completing LGE had R 0 resection and the number of lymph nodes dissected was 14±4. There were 3 cases with nerve bundle invasion, 2 cases with vascular invasion and 5 cases without nerve bundle and vascular invasion. The postoperative treatment time at intensive care unit and duration of hospital stay of the 10 patients completing LGE were (4.0±2.4)days and (7.2±1.5)days. (3) Follow-up. The 10 patients completing LGE were followed up and none of them died during the postoperative 30 days. Conclusions:LGE is safe and feasible. Combined with SLN can guarantee the oncology effect of surgery.

Objective To demonstrate the changes in flexor digitorum and extensor digitorum tension in the affected hands with shear-wave elastography (SWE) before and after manual digitorum sensory stimulation (MDSS) in hemiplegic patients with stroke. Methods A total of 51 hemiplegic post-stroke inpatients in the Department of Rehabilitation Medicine in Second Hospital of Anhui Medical University from April to June, 2020, underwent MDSS completed by a researcher who used a bare thumb and index finger to squeeze each nail bed as well as the sides of each fingertip in the affected hand. The stimulation intensity was the minimum that could cause finger extension without obvious pain, and the interval between two stimulations was five to ten seconds. Muscular tension of the flexor digitorum superficialis, flexor digitorum profundus, flexor pollicis longus and extensor digitorum were assessed with modified Ashworth Scale (MAS) and shear-wave velocity (SWV) of SWE on the affected side before and immediately after MDSS. MAS score was -1 as low muscular tension. Results The MAS scores of all the muscles significantly reduced after MDSS (|Z| > 2.843, P < 0.001); while the changes of SWV were not significantly in all the muscles with initially MAS score of 0 or -1 (t < 1.052, P > 0.05), and it reduced in those muscles with initial MAS scores of one to three (t > 2.672, P < 0.05). The SWV were positively correlated with the MAS scores both before and after MDSS (r > 0.334, P < 0.05). Conclusion MDSS can effectively, immediately, and safely relieves muscle spasms of the flexor digitorum and facilitate active finger extension in the affected hand for hemiplegic patients with stroke. SWE is useful for quantitatively and objectively evaluating muscular tension in the affected hand for hemiplegic patients with stroke.

ObjectiveTo investigate the changes of surface electromyography (sEMG) of the flexors and extensors of the affected fingers after manual digitorum sensory stimulation (MDSS) in the hemiplegic patients after stroke. MethodsFrom April to August, 2020, 50 stroke patients in Department of Rehabilitation Medicine, the Second Hospital of Anhui Medical University accepted MDSS on the nail beds and the third knuckles of affected fingers, until the fingers extended actively. The tension of affected flexor pollicis brevis, flexor digitorum superficialis and extensor digitorum were assessed with modified Ashworth Scale (MAS) before and immediately after stimulation; while the root mean square (RMS) of sEMG of bilateral flexor pollicis brevis, flexor digitorum superficialis and extensor digitorum were recorded. ResultsThe MAS score of all the muscles decreased after stimulation (|Z| > 2.699, P < 0.01), while the RMS of affected extensor digitorum increased (t = -2.069, P < 0.05). Compared with the unaffected ones, RMS of affected flexor pollicis brevis and extensor digitorum decreased before and after stimulation (t > 2.450, P < 0.05). ConclusionMDSS may immediately relieve the spasm of flexors of hemiplegic fingers after stroke, which associates with the promoting muscle strength of the extensors.
