Pulmonary endometriosis (PEM) is a rare disease with diverse clinical manifestations, most commonly presenting as hemoptysis, while patients presenting solely with pulmonary nodules are less common. Here, we report three female patients (aged 32, 19, and 46 years, respectively). One patient sought medical attention due to hemoptysis during menstruation, while the other two had no obvious symptoms and were found to have pulmonary nodules during routine physical examinations. Two patients had a history of cesarean section, and one had a history of miscarriage. Pathologically, one patient of PEM showed extensive hemorrhage in the alveolar spaces, with fragmented endometrial glandular epithelium observed within the hemorrhagic foci. The other two patients exhibited proliferative endometrial glands and stroma, surrounded by old hemorrhage. Immunohistochemistry revealed that the endometrial glands and stroma in all three patients were positive for estrogen receptor, progesterone receptor, and vimentin, with CD10 positivity in the endometrial stroma. All three patients were definitively diagnosed as PEM by pathology and underwent thoracoscopic pulmonary wedge resection. Follow-up periods were 18, 31, and 49 months, respectively, with no recurrence observed in any of the patients.
ObjectivesTo systematically review the safety of harmonic scalpel and conventional resection in superficial parotidectomy.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and CBM databases were electronically searched to collect randomized controlled trials (RCTs) or cohort studies of harmonic scalpel and conventional resection in superficial parotidectomy from the inception of the database to December, 2018. Two reviewers independently screened literatures, extracted data and assessed risk of bias of the included studies. Then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 10 studies involving 671 post-cesarean section patients (361 patients in harmonic scalpel group and 310 patients in conventional resection group) were included. The results of meta-analysis showed that: compared with conventional resection, harmonic scalpel had shorter operative time (MD=−23.82, 95%CI −31.20 to −16.44, P<0.000 01), less postoperative drain output (MD=−26.25, 95%CI −38.95 to −13.55, P<0.000 1), less intraoperative blood loss (MD=−23.78, 95%CI −28.64 to −18.91, P<0.000 01), shorter duration of hospital stay (MD=−1.19, 95%CI −2.14 to −0.23, P=0.02), and lower temporary facial nerve palsy rate (OR=0.27, 95%CI 0.14 to 0.50, P<0.000 1). However, there was no significant difference in the incidence of parotid gland leakage between two groups (OR=0.42, 95%CI 0.16 to 1.06, P=0.07).ConclusionsThe current evidence demonstrates that, compared to conventional resection, harmonic scalpel resection is safer. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
To evaluate the efficacy and the surgical procedures of submandibular sialoadenectomy by a modified retroauricular approach. Methods Between October 2008 and April 2009, 8 patients with benign submandibular gland disorders underwent removal of benign submandibular gland lesions using a retroauricular approach. There were 4 males and 4 females with an average age of 38.5 years (range, 32-54 years), including 3 pleomorphic adenoma and 5 chronic sialadenitis with sialol ithiasis. The disease duration was from 2 months to 5 years. The anterior facial vein and the facial artery were reserved only by the l igation of branching vessels in the submandibular gland. Results Submandibular sialoadenectomy were successfully performed in 8 cases. The operative time was 45-75 minutes (mean, 60 minutes). All incisions obtained heal ing by first intention. No nerve paralysis occurred, including marginal mandibular branch of the facial nerve, the l ingual nerve, and hypoglossal nerve. One patient had poor blood circulation of flap due to excessive traction during operation, but it returned normal after 24 hours without special treatment. Other flaps had good blood circulation. All patients were followed up 1-6 months (mean, 3 months). The incision scars were hidden with satisfactory appearance. Conclusion The modified retroauricular approach has some advantages such as simple operation, better cosmetic outcome, and no compl ication.
ObjectiveTo identify the risk factors of postoperative recurrence and survival for patients with hepatocellular carcinoma within Milan criteria following liver resection. MethodsData of 267 patients with hepatocellular carcinoma within Milan criteria who received liver resection between 2007 and 2013 in our hospital were retrospectively analyzed. ResultsAmong the 267 patients, 123 patients suffered from recurrence and 51 patients died. The mean time to recurrence were (16.9±14.5) months (2.7-75.1 months), whereas the mean time to death were (27.5±16.4) months (6.1-75.4 months). The recurrence-free survival rates in 1-, 3-, and 5-year after operation was 76.8%, 56.3%, and 47.6%, respectively; whereas the overall survival rates in 1-, 3-, and 5-year after operation was 96.6%, 82.5%, and 74.5%, respectively. Multivariate analyses suggested the tumor differentiation, microvascular invasion, and multiple tumors were independent risk factors for postoperative recurrence; whereas the tumor differentiation, positive preoperative HBV-DNA load, and preoperative neutrophil-to-lymphocyte ratio adversely influenced the postoperative survival. ConclusionsFor patients with hepatocellular carcinoma within Milan criteria after liver resection, the tumor differentiation, microvascular invasion, and multiple tumors contribute to postoperative recurrence; whereas the tumor differentiation, positive preoperative HBV-DNA load, and preoperative neutrophil-to-lymphocyte ratio adversely influence the postoperative survival.
In order to observe the morphological feature and blood supply of the pedicled trapezius myocutaneous flap, dissection was carried out on 114 sides of 54 cadavers. It was demostrated that trapezius muscle had multiple sources for its blood supply, including (1) dorsal scapular artery; (2)transvers cervical artery; (3) occipital artery and (4)spinal perforating artery. The dorsal scapular artery may originate from the same stem with the transvers cervical artery (68.4%), or originate seperatly (31.6%). Thirteen patients had radical resection for malignant tumour of head and neck, and were combined with pedicled trapezius myocutaneous flap, in which 6 with upper trapezius myocutaneous flap and 7 with lower trapezius myocutaneous flap. The results were fairly good. the advantages and disadvantages of the lower and upper trapezius myocutaneous flaps as well as the pectorlis major myocutaneous flap were discussed.
ObjectiveTo summarize the diagnosis and treatment process of a patient who underwent laparoscopic local excision of duodenal papillary tumor, and to explore the safety and feasibility of this surgery. MethodThe clinicopathologic characteristics and surgical procedure of the patient with duodenal papillary neuroendocrine tumor admitted to the West China Hospital of Sichuan University in June 2021 were retrospectively analyzed. ResultsThe patient underwent the laparoscopic local excision of duodenal papillary tumor + in situ cholangiojejunostomy and pancreaticojejunostomy. The operation lasted about 3 hours, the blood loss was about 20 mL, and the patient exhausted on the 3rd day after the operation. On the 7th postoperative day, the gastric tube was pulled out and oral feeding was started. On the 8th day, the plasma drainage tube was pulled out and the patient was discharged smoothly. There was no duodenal fistula, bleeding, wound infection, and other complications. After 6 months of follow-up, the general condition of this patient was good, and no tumor recurrence or metastasis was found. ConclusionLaparoscopic local excision is an appropriate option for benign or low-grade malignancies involving the duodenal papillary tumor.
ObjectiveTo explore the adjuvant treatment options for elderly patients or those with low cardiopulmonary function who cannot tolerate lobectomy for peripheral solid pathological stage ⅠA (pⅠA) non-small cell lung cancer (NSCLC). MethodsA retrospective analysis was conducted on the clinical data of patients with peripheral solid pⅠA stage NSCLC treated with lobectomy and compromised sublobar resection (CSR) in our center from 2018 to 2019. The incidence of postoperative complications and independent predictors of postoperative recurrence were analyzed. Patients in the CSR group were divided into a targeted therapy group, a chemotherapy group, and an observation group based on postoperative treatment measures. The 3-year recurrence-free survival (RFS) rate and 5-year overall survival (OS) rate of the three subgroups before and after propensity score matching (PSM) were compared. ResultsA total of 586 patients were included, including 288 males (49.15%) and 298 females (50.85%), with a median age of 64.00 years. There were 335 patients of lobectomy and 251 patients of compromised sublobar resection. There was no statistically significant difference in the incidence of postoperative complications between the lobectomy group and CSR group [RR=0.987, 95%CI (0.898, 1.085), P=0.789). Multivariate analysis showed that gender, tumor location, and size were independent risk factors for recurrence after CSR. After PSM, 17 patients were enrolled in each of the three subgroups of CSR. Kaplan-Meier survival curve analysis showed that there was no statistically significant difference in the 3-year RFS rate (P=0.115) and 5-year OS rate (P=0.101) between the targeted therapy group and the chemotherapy group after PSM, but both were significantly better than those in the observation group (P=0.041, P=0.009). Compared with lobectomy, there was no statistically significant difference in the 3-year RFS rate (P=0.069) and 5-year OS rate (P=0.540) in the targeted therapy group, while the chemotherapy group and observation group were significantly inferior to the lobectomy group (P<0.05). ConclusionCSR for treating elderly patients or those with low cardiopulmonary function with peripheral solid pⅠA stage NSCLC does not increase the incidence of postoperative complications. Gender, tumor location, and size are independent risk factors for postoperative recurrence. In terms of 3-year RFS rate and 5-year OS rate, adjuvant targeted therapy after CSR is not only superior to chemotherapy or observation but is also not inferior to lobectomy.
ObjectiveTo evaluate the mid- and long-term outcomes of different surgical techniques for subaortic stenosis.MethodsThe clinical data of 75 patients with subaortic stenosis who underwent surgery in our hospital from January 2008 to January 2018 were retrospectively analyzed, including 48 males and 27 females, with a median age of 72 (48, 132) months and mean weight of 21.35±15.82 kg. There were 40 (53.3%) patients combined with aortic regurgitation; 38 (50.7%) patients were the first time and 37 patients were the second time to receive the operation. According to the surgical techniques, 75 patients were divided into two groups: a group A (40 patients with simple subaortic membrane resection) and a group B (35 patients with subaortic membrane and muscle resection or modified Konno procedure).ResultsTwo (2.67%) patients died in hospital. There was one late death in the group B. The average preoperative and postoperative pressure gradient of all patients was 69.96±42.02 mm Hg and 7.44±12.45 mm Hg, respectively. All patients were followed up for 51 (12, 120) months. Pressure gradient at follow-up in the group A and the group B was 8.83±14.52 mm Hg and 5.86±9.53 mm Hg, respectively with no statistical difference (P=0.294). Four patients in the group A and 2 patients in the group B needed reintervention. However, there was no statistical difference in the long-term reintervention rate between the two groups (P=0.480).ConclusionFor the different degree of lesions in the left ventricular outflow tract, our management strategy is feasible. Although there is no statistical difference between two the groups in the long-term reintervention rate after simple valvular membrane resection, prolonged follow-up is necessary to examine the long-term outcomes of different surgical techniques.
ObjectiveTo investigate the effectiveness of levator muscle resection combined with Mustarde’s double Z-plasty to correct blepharophimosis-ptosis-epicanthus inversus syndrome (BPES).MethodsBetween March 2015 and June 2017, one-stage operation of levator muscle resection combined with Mustarde’s double Z-plasty were performed on 26 children with bilateral BPES. There were 16 boys and 10 girls with an average age of 7 years (range, 4-14 years). All patients marked the four typical signs of BPES. There were 7 cases accompanied with a low nasal bridge, and 20 cases with amblyopia and strabismus. The length of eye fissure was (19.5±4.5) mm, the width of eye fissure was (2.5±1.6) mm, the diameter of inner canthus was (42.1±6.5) mm, and the muscular strength of levator palpebrae superioris was (5.5±1.3) mm.ResultsAll the incisions healed by first intention. Twenty-three patients were followed up 2-12 months, with an average of 10 months. Among which, 2 cases were less corrected, 3 cases were over corrected, 6 cases had poor curvature of the eyelid. No eyelid internal and external pronation or keratitis occurred. Amelioration of blepharoptosis and epicanthus was achieved in the other patients, and the double eyelid fold was naturally smooth. At 7 days after operation, the length of eye fissure was (27.2±1.9) mm, the width of eye fissure was (12.5±1.3) mm, and diameter of inner canthus was (29.4±2.6) mm, which were superior to preoperative values (t=0.127, P=0.042; t=0.341, P=0.029; t=0.258, P=0.038). There was no angular deformity caused by the width and length regressions of eye fissures.ConclusionThe levator muscle resection combined with Mustarde’s double Z-plasty can effectively correct BPES and obtain good effectiveness.
ObjectiveTo summarize short-term and long-term effects of ex vivo liver resection followed by autotransplantation (Abbreviation: autotransplantation) in treatment of advanced hepatic alveolar echinococcosis (HAE).MethodThe clinical data and follow-up data of 17 patients with advanced HAE who underwent autotransplantation from November 2016 to July 2019 in the Ganzi Tibetan Autonomous Prefecture People’s Hospital were retrospectively analyzed.ResultsThe autotransplantations were performed successfully in the 17 patients with advanced HAE. Ten patients underwent the inferior vena cava (IVC) reconstruction with autologous saphenous veins, 5 patients underwent the artificial revascularization, 1 patient underwent the direct anastomosis of the original IVC, and 1 patient didn’t reconstructed (the retroperitoneal collateral circulation was abundant). The mean liver graft mass was 681.3 g (365–1 350 g) and operation time was 11.5 h (9–16 h). The median anhepatic period was 312 min (175–450 min), blood loss was 2 000 mL(950–4 500 mL), red blood cell suspension transfusion was 6.4 U (1–20 U), and fresh frozen plasma was 1.1 L (0.8–2.0 L). The postoperative hospital stay was 5 to 45 d with an average of 25.6 d. There were 4 patients with the postoperative hepatic enveloping effusion, 1 patient with bile leakage, and 1 patient with bile duct stenosis. All of them were treated and cured, and no death occurred. The follow-up time of 17 patients was 3 to 35 months with an average of 9.5 months, no recurrence of HAE and distant metastasis were observed.ConclusionsIn highlands, autotransplantation in treatment of advanced HAE patients with different IVC reconstruction is satisfactory, but it has a higher risk and is difficult. Choice of intraoperative reconstruction materials, judgment of posterior peritoneal collateral circulation, presence or absence of tension in end-to-end anastomosis of the IVC require precise consideration. At the same time, anticoagulation therapy and complications management are difficult, and it is only suitable for plateau medical center with rich experience.
