The operative strategy after palliative shunt for corrected transposition of great artery (cTGA) with left ventricular outflow tract obstruction and cardiac malpostion / 中国胸心血管外科临床杂志

@#Objective    To explore the operative strategy after palliative shunt for correcting congenitally corrected transposition of great artery (cTGA) patients with left ventricular outflow tract obstruction (LVOTO) and cardiac malpostion. Methods    We retrospectively analyzed the clinical data of 54 patients with onsecutive cTGA with LVOTO and cardiac malpositon from June 2011 to May 2019. The patients were devided into two groups. There were 24 patients (16 males and 8 females at mean age of 5.4±2.2 years) who underwent one and a half ventricle repair as a one and half ventricle group. And there were 30 patients (19 males and 11 females at age of 8.6±6.2 years) who underwent one ventricle repair operation as a one ventricle group. Follow-up data were collected by telephone interviews. Results    There was no statistical difference in systemic atrioventricular valve regurgitation and systemic ventricular ejection fraction between the two groups (P>0.05). Compared with one and a half ventricle group, the cardiopulmonary bypass time (CPB) time, mechanical ventilation time and intensive care unit stay were significant shorter than those in the one ventricle group (P<0.05), but prolonged pleural effusions developed more frequently in the one ventricle repair group (P<0.05). There was no in-hospital death but 1 follow-up death in each group. The follow-up time was 49 (17-38) months in the one and half ventricle group at follow-up rate of 93.9%, and 47 (12-85) months at follow-up rate at 90.9% in the one ventricle group. One and a half ventricle group had better systemic ventricular ejection fraction (EF) than that in the one ventricle repair group. And the rate of heart function (NYHA) class Ⅲ and class Ⅳ in one and a half ventricle group was lower than that in the ventricle group. No significant difference of survival and freedom from re-intervention probability between the two groups was found. Conclusion    For patients of correction of cTGA with LVOTO and cardiac malposition after palliative shunt, the one-and-a-half ventricular repair procedure is ideal operative strategy.

Perioperative care for patients undergoing secondary Stanford B-type aortic dissection / 中国实用护理杂志

Objective To explore the perioperative nursing experience of Stanford B- type aortic dissection patients who underwent re- do operations. Methods Preoperative and postoperative nursing data were collected from 14 Stanford B-type aortic dissection patients who were received reoperations from January 2015 to April 2018. Results Thirteen patients were discharged successfully postoperatively,and 1 patient was transferred to the rehabilitation hospital for further treatment. Conclusions The most important nursing principles are detailed understanding of the complicated illness of patients and personalized perioperative psychological nursing for such kind patients. It is so vital to observe preoperative clinic signs, to evaluate pain, to control of blood pressure and heart rate, to strengthen basic nursing, to monitor postoperative body temperature, respiration, and blood oxygen. Besides that, evaluating patients′ consciousness and physical activities, strengthening wound care and complications nursing,educating functional exercise and health knowledge, could make patients recover earlier and better.

Evaluation of Fallopian Tube Function After Laparoscopic Salpingotomy for Ectopic Pregnancy / 中国微创外科杂志

Objective To assess patient ’ s fallopian tube function after laparoscopic salpingotomy for tubal ectopic pregnancy.Methods We observed the degree of pelvic adhesion and previous tubal patency by laparoscopic secondary exploration. The fallopian tube function were evaluated in 24 cases ( 26 fallopian tubes ) which had experienced laparoscopic salpingotomy. Results There were 4 cases of severe adhesions (16.7%), 4 cases of moderate adhesions (16.7%), 5 cases of mild adhesions (20.8%), and 11 cases of minor adhesions (45.8%).The status of fallopian tubes:tubal rapture and tissue absence were seen in 11 oviducts (42.3%), intact but obviously shortened oviduct with distal hydrops was seen in 11 oviducts (42.3%), and normal oviduct was recorded in 4 oviducts (15.4%).The methylene blue flow test was performed in the 26 tubes, showing 23 (88.5%) occluded and 3(11.5%) patent. Conclusions The fallopian tubes have incomplete shapes after laparoscopic tubal fenestration for ectopic pregnancy in most patients.We confirm that laparoscopic salpingotomy can not preserve the fertility effectively.

Analysis of secondary surgery for neovascular glaucoma after vitrectomy in PDR / 国际眼科杂志(Guoji Yanke Zazhi)

To investigate risk factors and efficacy of reoperation for neovascular glaucoma ( NVG) secondary to vitrectomy in proliferative diabetic retinopathy (PDR). ●METHODS:Seven cases (7 eyes) from October, 2009 to December, 2012 were analyzed retrospectively. All the patients had NVG after the primary vitrectomy for PDR and were performed secondary vitrectomy combined with laser photocoagulation . ●RESULTS: The mean intraocular pressure ( lOP) was (11. 21±4. 22)mmHg before primary surgery. The number of laser spots ranged from 622 to 1124 during the first vitrectomy. Cataract extraction was performed in all 7 cases and intraocular lens was implanted in 5 cases. The mean lOP was (10. 11± 3. 62) mmHg during 2mo after the primary surgery. During follow- up, all the patients had significantly progressive intraocular inflammation. Vitreous hemorrhage was not absorbed completely in 2 cases and recurrent vitreous hemorrhage occurred in the other 5 cases. Five cases had poor glycemic control and the other 2 cases had bad blood pressure control. NVG occurred in all 7cases. The mean lOP was (41. 13 ± 7. 76) mmHg before the secondary surgery. After the secondary surgery, the lOP were under control in 5 cases. For the other 2 cases, the lOP was controlled in one case by transscleral cyclophotocoagulation, another one was lost in follow-up with uncontrolled lOP. ●CONCLUSlON: Primary vitrectomy combined with lens extraction, insufficient laser speckle, unabsorbed and recurrent vitreous hemorrhage, intraocular inflammation and systemic condition may be the risk factors associated with the occurrent of NVG after vitrectomy in PDR. Secondary vitrectomy combined with sufficient retinal photocoagulation is efficiency for NVG after vitrectomy for the PDR.

The Minimal Postoperative Follow-Up Period to Determine Secondary Surgery in Patients with Intermittent Exotropia

PURPOSE: We investigated the recommended minimum postoperative follow-up period for the determination of secondary corrective surgery for the consecutive esotropia (ET) and recurrent exotropia (XT) after the first intermittent XT surgery. METHODS: The medical records of 728 patients who underwent surgical treatment for intermittent XT between 2004 and 2009 with a minimum postoperative follow-up of 1 year were retrospectively reviewed. Each patient underwent a detailed sensory and motor examination, including measurements of near and distance stereoacuity, alternating-cover test, and extraocular muscle function testing. Consecutive ET was defined as esodeviation over 15 prism diopter (PD) at distance persisting for more than 6 months after surgery despite medical treatment. Recurrent XT was defined as exodeviation over 15 PD at distance after surgery despite medical treatment. RESULTS: The mean age of the 728 patients at first surgery was 7.5 years (range, 22 months - 30 years). When only the motor outcome was considered, 663 patients (91.1%) had an orthrotropia at the final follow-up and 44 patients (6.0%) among consecutive ET patients and 21 patients (2.9%) who had a recurrent XT underwent secondary surgical correction. Binocularity decreased postoperatively in patients with consecutive ET (p < 0.001), whereas the other patients demonstrated improved stereopsis postoperatively (p = 0.041, 0.021). Patients with consecutive ET showed esodeviation over 10 PD when compared with orthotropia after 2 months postoperatively (p = 0.005). At 6 months postoperatively, 17 (81.0%) of 21 patients with recurrent XT showed orthotropia with an exodeviation over 11 PD after 18 months postoperatively. CONCLUSIONS: The success rate of surgical correction for intermittent XT showed a favorable outcome. However, careful concern for consecutive ET and recurrent XT are required in postoperative follow-up periods. Over-corrected or consecutive ETs need early surgical correction because no further improvement of ocular alignment will occur after 2 months postoperatively and delayed correction can result in poor sensory binocularity. Under-corrected or recurrent XT should be observed for an extended period because of the exotropic drift after surgery, thus requiring periodic long term follow-up for secondary surgery at least for 18 months postoperatively.

Revision Surgery after Carpal Tunnel Release for Idiopathic Carpal Tunnel Syndrome

PURPOSE: To report the causes of recurrent and persistent symptoms after carpal tunnel release and to evaluate the result of revision surgery. MATERIALS AND METHODS: wenty one patients who underwent surgery for recurrent or persistent carpal tunnel syndrome after carpal tunnel release were studied. The mean age was 59 years. There were 2 men and 19 women. The mean time interval between first operation and revision surgery was 29.8 months, and mean follow up period was 10.6 months. The operations were done by single surgeon. RESULTS: The most common cause of failed carpal tunnel release was scar adhesion, which was observed in nine cases. Other causes included incomplete release of transverse carpal ligament in six, scar adhesion with incomplete release in three, iatrogenic median nerve injury in two, and unrecognized calcification in one. Following revision surgery, 15 cases (71%) showed alleviation of symptoms. CONCLUSION: In cases of recurrent or persistent carpal tunnel syndrome following carpal tunnel release, evaluation of the causes is essential in performing revision surgery.

Aortic Root Replacement for Perivalvular Leakage after Aortic Valve Replacement for Marfan Syndrome with Severe Thoracic Deformity / 日本心臓血管外科学会雑誌

The number of operations performed for cardiovascular disease has increased since recent improvements in diagnostic and the therapeutic technology have led to a remarkable increase in the life expectancy of patients with Marfan syndrome. On the other hand, operative procedures can be difficult when patients have complications of connective tissue abnormalities such as thoracic deformities, lung diseases and ophthalmic lesions. Although recent surgical outcomes have improved, those of secondary surgery are more difficult. We describe aortic root replacement to treat perivalvular leakage after aortic valve replacement in a patient with Marfan syndrome with a severe thoracic deformity.

Result of Secondary Surgery after Primary Surgery for Esophageal Atresia Anomalies

We reviewed the records of 25 patients who were re-operated upon after primary repair of esophageal atresia with or without fistula at the Department of Pediatric Surgery, Seoul National University Children's Hospital, from January 1997 to March 2007. Types of the esophageal atresia anomalies were Gross type A in 5 patients, C in 18, and E in 2. The indications for re-operation were anastomosis stricture (n = 14), tracheo-bronchial remnant (n = 4), persistent anastomosis leakage (n = 3), recurrent tracheo-esophageal fistula (n = 2) and esophageal web (n = 2). The interval between primary and secondary surgery was from 48 days to 26 years 5 months (mean: 2 years and 4 months). Four patients required a third operation. The interval between the second and third operation was between 1 year 1 month and 3 year 10 month (mean: 2 years 5 months). Mean follow up period after last operation was 35 months (1 years-8 years 6 months). The secondary surgery was end-to-end esophageal anastomosis in 15, esophagoplasty in 5, gastric tube replacement in 5. After secondary operation, 6 patients had anastomosis stricture (4 patients were relieved of the symptoms by balloon dilatation, 2 patients underwent tertiary operation). Five patients had leakage (sealed on conservative management in all). Two patients had recurrent tracheo-esophagel fistula (1 patient received chemical cauterization and 1 patient underwent tertiary operation). Currently, only one patient has feeding problems. There were no mortalities. Secondary esophageal surgery after primary surgery for esophageal atresia was effective and safe, should be positively considered when complications do not respond to nonoperative therapy.

Hiperparatireoidismo secundário: fatores prognósticos de recidiva atribuída ao implante após paratireoidectomia total e auto-implante / Secondary hyperparathyroidism: prognostic factors of graft-dependent recurrence after total parathyroidectomy and parathyroid autotransplantation

Nos casos de hiperparatireoidismo secundário onde não é possível o tratamento clínico, é indicada a paratireoidectomia. No Serviço de Cirurgia de Cabeça e Pescoço do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, o tipo de cirurgia utilizada é a paratireoidectomia total com auto-implante de paratireóide em membro superior. Nesses casos, ao contrário da paratireoidectomia total, pode haver recidiva do hiperparatireoidismo no sítio do implante, com sintomas sistêmicos e com necessidade de intervenção para retirada do tecido hiperplásico. Já na paratireoidectomia total, há hipoparatireoidismo definitivo e risco de doença óssea adinâmica. O presente estudo tem como escopo avaliar os pacientes submetidos a paratireoidectomia com implante e esclarecer se há fatores clínicos e de imunohistoquímica que possam indicar antes da cirurgia algum risco de recidiva no implante.

When clinical treatment of secondary hyperparathyroidism fails, parathyroidectomy is mandatory. Total parathyroidectomy and immediate parathyroid autotransplantation in the forearm is the treatment of choice at Head and Neck Surgery of Hospital das Clínicas of University of São Paulo Medical School. In this cases, recurrent hyperparathyroidism may be caused by hyperplastic graft tissue. Without autotransplantation, adinamic bone disease may occur. The present study seek to evaluate patients submitted to total parathyroidectomy and autotransplantation and try to clarify clinical or immunohistochemical.

Factors Affecting Survival Rate Following Hepatic Resection for Metastatic Colorectal Cancer / 한국간담췌외과학회지

BACKGROUND/AIMS: A hepatectomy for liver metastases from colorectal cancer has recently received general acceptance as a safe, potentially curative treatment modality due to its low surgical mortality and significant improvement of survival rates after resection. However, criteria for the selection of patients and treatment modalities remains controversial. The aim of study was to determine the prognostic factors. in patients who had undergone a hepatic resection for metastatic colorectal cancer. METHODS: Twenty-four patients who had underdone initial hepatic resection for liver metastases from colorectal cancer between 1992 and 2002 were analyzed with regard to clinical and pathological parameters. The survival rate was calculated using the Kaplan-Meier method and Cox regression hazard model. The mean follow up period was 37 months. RESULTS: The overall 5-year survival rate was 29.3%, with a mean survival of 39 months. There were 10 (41.3%) and 14 (58.7%) cases of synchronous and metachronous metastasis, respectively. The 5-year survival rate was shown to be significantly lower in patients with more than 4 metastases (p=0.01), bilobar metastasis (p=0.02) and vascular invasion (p=0.01). The number of hepatic metastases (p= 0.02) has been demonstrated as an independent factor for the 5-year survival. CONCLUSION: Patients with multiple, bilobar hepatic metastases and vascular invasion demonstrated a poor survival rate. Therefore, in patients with poor prognostic factors, curative surgical resection, accompanied by a multimodality treatment, is necessary for an improved survival.
