BACKGROUND: Congenital diaphragmatic hernia (CDH) is a developmental defect that causes herniation of abdominal organs into the thoracic cavity with significant morbidity. Thoracoscopic repair of CDH is an increasingly prevalent yet controversial surgical technique, with limited long-term outcome data in the Asian region. The aim of this study was to compare open laparotomy versus thoracoscopic repair of CDH in paediatric patients in a major tertiary referral centre in Asia.
METHODS: We performed a retrospective analysis of neonatal patients who had open laparotomy or thoracoscopic repair for CDH in our institution between July 2002 and November 2021. Demographic data, perioperative parameters, recurrence rates and surgical complications were analysed.
RESULTS: 64 patients were identified, with 54 left sided CDH cases. 33 patients had a prenatal diagnosis and 35 patients received minimally invasive surgical repair. There was no significant difference between open and minimally invasive repair in recurrence rate (13 % vs 17 %, P = 0.713), time to recurrence (184 ± 449 days vs 81 ± 383 days, P = 0.502), or median length of ICU stay (11 ± 14 days vs 13 ± 15 days, P = 0.343), respectively. Gastrointestinal complications occurred in 7 % of neonates in the open group and none in the thoracoscopic group. Median follow-up time was 9.5 years.
CONCLUSIONS: This study is a large congenital diaphragmatic hernia series in Asia, with long term follow-up demonstrating no significant difference in recurrence rate, time to recurrence or median length of ICU stay between open and minimally invasive repair, suggesting thoracoscopic approach is a non-inferior surgical option with avoidance of gastrointestinal complications compared to open repair.
METHODS:
METHODS: Retrospective Cohort Study.

BACKGROUND: To perform a systematic review on contemporary outcomes of endovascular repair and open surgical repair (OSR) for the treatment of mycotic aortic aneurysm (MAA).
METHODS: A comprehensive literature search on the management of MAAs with endovascular repair or OSR was performed between January 1998 and January 2023. Patient demographics, early and late outcomes were analyzed with respect to treatment modality and MAA location.
RESULTS: Forty-eight articles were included, encompassing a total of 1,358 patients (75.8% male; mean age 66.9 years; 1,372 aneurysms) treated by open (49.8%) or endovascular (50.2%) repair. Salmonella spp., and Staphylococcus spp. were the most prevalent pathogens in Asian and European countries respectively. An increasing number of descending thoracic MAAs were managed by endovascular repair (27.9% vs. 12.8%). Early mortality rates for supra- and infra-renal MAAs managed by endovascular repair were lower than OSR (suprarenal 5.4% vs. 43.2%; infrarenal 1.8% vs. 16.7%). Overall, endovascular repair demonstrated lower intraoperative (1.0% vs. 1.8%) and early mortality (6.5% vs. 15.9) rates than OSR. However, endovascular repair was associated with higher late sepsis rate (5.7% vs. 0.9%) and reintervention rate (17.6% vs. 7.3%). Pooled survival rates at 1- and 5-year were similar between the 2 groups.
CONCLUSIONS: Current literature suggest that endovascular repair is an effective and safe alternative to OSR for descending thoracic, suprarenal, and infrarenal MAAs. However, endovascular repair is associated with higher risk of infection-related complications and reintervention during follow-up.

Recurrent incisional hernias are challenging, and their surgical outcomes have not been well studied. We aimed to analyze the outcomes of recurrent incisional hernia repair in a propensity score-matched cohort study on laparoscopic intra-peritoneal onlay mesh repair (lap. IPOM) versus open sublay repair.
All consecutive patients who had undergone open sublay repair and lap. IPOM of recurrent incisional hernia between January 2015 and December 2021 at a tertiary hernia center was identified. One-to-one propensity score matching was used to achieve a balanced exposure groups at baseline.
Of 255 patients, 85/95 with open sublay repair were matched to 85/160 with lap. IPOM. Before matching, the open sublay group had significantly larger hernia defects (6.3 cm vs. 5.0 cm) than the lap. IPOM group. Other major baseline imbalances were also found in body mass index (BMI), obesity and European Hernia Society (EHS) width classification. The pre-match results showed that the lap. IPOM group had significantly shorter operative time (median 75 vs. 95 min) and shorter postoperative hospital stay (median 8 vs. 11 days) compared with the open sublay group. Wound infection (8.4% vs. 1.9%) and hematoma (5.3% vs. 0.6%) occurred more frequently after open sublay repair. After matching, baseline characteristics were well balanced. The recurrence rate and incidence of complications were comparable between the two groups. However, the post-match analysis still showed that lap. IPOM was associated with decreased length of postoperative stay.
The outcomes of recurrent incisional hernia surgery after lap. IPOM and open sublay repair appear similar, except that the former had shorter length of postoperative stay. However, the poor outcomes were more likely associated with the unfavorable risk profiles, such as larger defect size, rather than the procedure technique itself.

BACKGROUND: This study aimed to define the effectiveness of thoracoscopic versus open repair of gross type C oesophageal atresia (EA) based on the experience of a single centre over a decade.
METHODS: This retrospective cohort study included patients who were admitted to Hunan Children\'s Hospital between January, 2010 and December, 2021 and underwent repair surgery for type C EA.
RESULTS: A total of 359 patients underwent type C EA repair during the study period, of which 142 were completed via an open approach and 217 were attempted via a thoracoscopic approach (seven converted to open surgery). There were no differences in the demographics or comorbidities between the patients of thoracoscopy and thoracotomy (open repair) groups. The median operating time was 109 [90, 133] min in the thoracoscopic surgery group, which was slightly shorter than that in the open repair group (115 [102, 128] min, p = 0.059). Anastomotic leakage occurred in 41 (18.9%) and 35 (24.6%) infants in the thoracoscopic and open surgery groups, respectively (p = 0.241). Thirteen patients (3.6%) died in the hospital without significant differences in the repair approach. With a median follow-up of 23.7 months, 38 (13.6%) participants had one or more anastomotic strictures requiring dilatation, without significant differences in the repair approach (p = 0.994).
CONCLUSIONS: Thoracoscopic repair of congenital EA is safe, and has perioperative and medium-term outcomes similar to those of open surgery. This technique is recommended only in hospitals with experienced teams of endoscopic paediatric surgeons and anaesthesiologists.

Purpose: In children, pediatric inguinal hernia (PIH) is a prevalent condition. PIH is currently more frequently managed by laparoscopic closure of the hernia sac. We improved this minimally invasive technique; that is, laparoscopic two-hook hernia needle percutaneous extraperitoneal internal ring closure. Safety and effectiveness were evaluated by comparing the differences between laparoscopic repair (LR) and open repair (OR) in terms of operation time, surgical complications, contralateral metachronous hernia incidence, and recurrence rate. Methods: A retrospective clinical data analysis was performed on pediatric patients who had hernia surgery utilizing the LR or OR method between June 2019 and June 2021. Medical records of all of the children were gathered, and clinical traits, information about the procedure, and follow-up were all analyzed. Results: A total of 370 patients\' inguinal hernias were repaired. For 136 patients undergoing OR and 234 patients undergoing LR, all procedures were completed satisfactorily. There were 98 cases of bilateral hernias and 272 cases of unilateral hernias (180 on the right side and 92 on the left). In the LR group, 58 patients who had been initially diagnosed with unilateral hernias developed contralateral occult hernias intraoperatively. Inguinal hernia operations took an average of 13.82 (LR) and 32.07 (OR) minutes for unilateral cases, and 21.00 (LR) and 54.85 (OR) minutes for bilateral cases. For LR and OR, the average follow-up time was 22.41 months and 23.10 months, respectively. The perioperative complications included peritoneal rupture in 3 patients, scrotal edema or hematoma in 5, hydrocele in 3, and groin pain in 6. In the LR group, 1 patient experienced the postoperative recurrence, whereas 8 individuals in the OR group did. Conclusions: Our initial research showed that laparoscopic two-hook hernia needle percutaneous extraperitoneal internal ring closure inguinal hernia repair is a safe and effective procedure. The LR method has the benefits of concealing the incision, a quicker procedure, having a lower risk of complications, and finding contralateral patent processus vaginalis. Therefore, promoting and using this surgical technique in clinical practice are merited. Clinical Trial Registration number: Medical Association of Xiangtan (2022-xtyx-28).

Rotator cuff injuries are common, and morbidity increases with age. The asymptomatic full-thickness tear rate is 40% in the over 75-year-old population.
This study aimed to systematically review the literature on the outcomes of rotator cuff repair among >75 years old patients.
Systematic review.
A systematic review of the literature was performed following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search was performed in the electronic databases of PubMed, Medline, Embase, and The Cochrane Library. Studies in English evaluating repair of full-thickness rotator cuff tears in patients aged >75 years were included.
Six studies were reviewed, including 311 patients (313 shoulders) treated with arthroscopic and/or open rotator cuff repair. Sixty-one patients were lost to follow-up, leaving 252 shoulders with outcome data. Patients in this age group demonstrated a significant improvement in the clinical and functional scores after rotator cuff repair, with a high satisfaction rate. The mean American Shoulder and Elbow Surgeons scores improved from 43.8 (range, 42.0-45.5) preoperatively to 85.3 (range, 84.0 to 86.5) postoperatively, and the mean Constant scores improved from 45.4 (range, 34.7-55.5) to 78.6 (range, 67.0-91.6). Pain, evaluated in all studies by the visual analog scale for pain, showed a significant improvement at the last follow-up compared with the mean preoperative score. Furthermore, range of motion and return to daily activities and sports gained marked improvements.
Rotator cuff repair in patients aged >75 years could achieve high clinical success rates with good outcomes and pain relief. Although patients in this age group are at a high risk of retear, rotator cuff repair may offer a good option with significant functional and clinical improvement.

OBJECTIVE: To provide updated, pooled evidence on clinical outcomes among octogenarians (aged ≥80 years) with abdominal aortic aneurysm (AAA) managed by elective endovascular repair, compared to conventional open repair.
METHODS: PubMed, Embase, and Scopus databases were systematically searched. Studies that were either observational or randomized controlled trials were considered for the review. Included studies were conducted in elderly subjects (≥80 years) with AAA, and clinical and mortality outcomes were compared between endovascular and open surgical repair. Those reporting on outcomes of patients with urgent repair were excluded. The primary outcomes of interest were mortality and risk of complications. The pooled effect sizes were reported as odds ratio (OR) for categorical outcomes and weighted mean difference (WMD) for continuous outcomes. STATA software was used for statistical analysis.
RESULTS: The meta-analysis included 15 studies. Compared to those undergoing open repair, patients receiving endovascular repair had significantly reduced risk of immediate post-operative mortality (OR .23, 95% CI: .20, .27), overall complication (OR .30, 95% CI: .20, .44), cardiac (OR .23, 95% CI: .16, .35), renal (OR .29, 95% CI: .18, .46), pulmonary (OR .14, 95% CI: .09, .21) and bleeding related (OR .59, 95% CI: .42, .83) complications. The risk of mortality at latest follow up (at 36 months and 60 months) was similar in the two groups. The total blood loss (ml) (WMD -1126.47, 95% CI: -1497.81, -755.13), operative time (min) (WMD -29.40, 95% CI: -56.19, -2.62), length of intensive care unit stay (days) (WMD -2.27, 95% CI: -3.43, -2.12) and overall hospital stay (days) (WMD -6.64, 95% CI: -7.60, -5.68) was significantly lower in those undergoing endovascular repair.
CONCLUSIONS: Endovascular repair appears to be better than open repair of AAA in this high-risk, frail population, with respect to short term outcomes. The benefits of reduced risk of short term mortality, complications, and better peri and post-operative outcomes may be considered when making a choice between these two surgical approaches. Randomized controlled trials are needed to provide reliable evidence on the effect of EVAR on long term survival.

UNASSIGNED: Endovascular aneurysm repair (EVAR) is often seen as the first choice treatment for patients with abdominal aortic aneurysm (AAA), particularly high-risk patients, yet the long-term survival rate and improvement in quality of life are still unclear. In order to seek the value of EVAR to the entire healthcare field, we conducted a retrospective study to evaluate whether the improvement EVAR can truly bring to the quality of medical care in the era of value-based healthcare.
UNASSIGNED: We included AAA patients who underwent surgical treatment in the Department of Vascular Surgery, First Hospital of China Medical University, from January 1, 2004, to December 31, 2019 and evaluated surgery procedure data, short-term and long-term mortality, complications, prognoses, and medical costs.
UNASSIGNED: We analyzed 507 patients with AAA who underwent open repair (n = 232) or EVAR (n = 275) over a 15-year period. The operative time, blood loss, blood transfusion rate, and postoperative length of hospital stay of the EVAR group is significantly lower than which of the open repair group. Meanwhile, neither short-term nor long-term mortality rates shows significant differences between the two groups. On the other hand, the complication rate of the EVAR group was significantly higher than that of the open repair group. Lastly, the total cost of EVAR was significantly higher than that of open repair.
UNASSIGNED: Existing evidence suggests that EVAR improves neither short-term nor long-term survival rate compared with open surgery. In contrast, the complication rate and the reintervention rate in the EVAR group were higher than those in the open surgery group. Moreover, the cost of EVAR and that paid by medical insurance were higher than those for open surgery. For patients with a long-life expectancy, in order to ensure that patients receive appropriate and effective care, surgeons should choose a suitable method that considers both the quality of medical care as well as the expense accordingly.

BACKGROUND: Hepatic artery aneurysm (HAA) is the second most common visceral aneurysm. A significant number of hepatic aneurysms are found accidentally on examination. However, their natural history is characterized by their propensity to rupture, which is very serious and requires urgent treatment. An emergent giant hepatic aneurysm with an abdominal aortic dissection is less commonly reported.
METHODS: We report the complicated case of a giant hepatic aneurysm with an abdominal aortic dissection. A 66-year-old female presented with the complaint of sudden upper abdominal pain accompanied by vomiting. Physical examination showed that her blood pressure was 214/113 mmHg. Her other vital signs were stable. Computed tomography found a giant hepatic proper aneurysm and dissection of the lower segment of the abdominal aorta. Furthermore, angiography showed a HAA with the maximum diameter of approximately 56 mm originating from the proper hepatic artery and located approximately 15 mm from the involved bifurcation of the left and right hepatic arteries with no collateral circulation. Therefore, we decided to use a stent to isolate the abdominal aortic dissection first, and then performed open repair. After the operation, the patient recovered well without complications, and her 3-month follow-up checkup did not reveal any late complications.
CONCLUSIONS: Open surgery is a proven method for treating giant hepatic aneurysms. If the patient\'s condition is complex, staged surgery is an option.

In the present study, we have reported the midterm results of endovascular repair of acute zone 0 intramural hematomas (IMHs) with the most proximal tear or ulcer-like projection (ULP) in the descending aorta.
Data from patients with acute zone 0 IMH with the most proximal tear or ULP in the descending aorta from January 1, 2010, to December 31, 2019, were retrospectively reviewed. We performed Kaplan-Meier curves to calculate the intervention-free survival and survival after endovascular or open surgical repair. We used propensity score matching to compare the outcomes of endovascular and open surgical repair.
The present study included 99 patients. Of the 99 patients, 34 had initially received medical treatment. The 0.5-, 1-, and 3-year intervention-free survival rates for the 34 patients were 23.5%, 17.6%, and 14.7%, respectively. Of the 99 patients, 51 had undergone endovascular therapy, 27 after initial medical treatment. Most of these 51 patients had had a maximal diameter of the ascending aorta of <50 mm and a maximal diameter of IMH in the ascending aorta of <10 mm. The 1-, 3-, and 5-year survival rate for the endovascular group was 98.0%. Finally, 42 patients had undergone open surgery (3 after medical treatment), and the 1-, 3-, 5-year survival rates were all 92.9%. After propensity score matching, no statistically significant difference was found in the 30-day and follow-up mortality. However, endovascular repair was associated with a shorter operation time (69 vs 314 minutes; P < .001), shorter length of intensive care unit stay (24 vs 70 hours; P = .001), and shorter length of hospital stay (7 vs 12 days; P = .011).
For patients with acute zone 0 IMH and the most proximal tear or ULP in the descending aorta, in addition to open surgery, endovascular repair is an option if the maximal diameter of the ascending aorta is <50 mm and the maximal diameter of the IMH in the ascending aorta is <10 mm.
