Pneumothorax during pediatric laparoscopic surgery is a potentially fatal complication that may not be promptly recognized. It can occur due to congenital anatomical abnormalities, pre-existing pulmonary disease, or operative factors during laparoscopy. Clinical presentation may range from asymptomatic to acute respiratory distress, pleuritic chest pain, and even life-threatening circulatory collapse. Here, we report a case of sudden intraoperative pneumothorax accompanied by extensive subcutaneous emphysema of the neck and chest wall during laparoscopic high ligation of the hernial sac in a child. The child presented with a reducible left lower abdominal mass and mild pain 3 days prior but did not seek medical attention. Symptoms worsened 1 day prior to admission, with difficulty reducing the mass. On April 8, 2021, the patient was admitted to the Department of Anesthesiology, Zhuzhou Hospital Affiliated to Xiangya School of Medicine of Central South University, with a diagnosis of "left inguinal hernia." On the second day of hospitalization, laparoscopic high ligation of the left inguinal hernia sac was performed under general anesthesia. During the procedure, the patient developed a sudden increase in airway pressure, marked hemodynamic fluctuations, crepitus in the neck and right anterior chest regions, and significantly diminished breath sounds in the right lung. Emergent bedside chest X-ray confirmed a right-sided pneumothorax. Immediate intervention including thoracic needle decompression, closed thoracic drainage, the lung re-expansion was performed. The patient was discharged on the 7th postoperative day with full recovery. This case highlights the need for clinicians to remain vigilant for iatrogenic pneumothorax during pediatric laparoscopic surgery. Close intraoperative monitoring of vital signs is crucial for early detection, recognition, and timely management of pneumothorax to ensure patient safety during minimally invasive procedures.

Objective: To investigate the effect of laparoscopic extraperitoneal (LSEP) high ligation of the spermatic vein in the treatment of varicocele. METHODS: We retrospectively analyzed the clinical data about 80 cases of varieocele, 48 treated by LSEP and the other 32 by laparoscopic transabdominal retroperitoneal (LSTR) high ligation of the spermatic vein. We recorded the semen parameters before and at 1, 3 and 6 months after surgery, intraoperative blood loss, operation time, postoperative complications, time of gastrointestinal function recovery and rate of pregnancy, followed by comparison of the data obtained between the two groups of patients. RESULTS: Semen parameters were remarkably improved in both the LSEP and LSTR groups of patients postoperatively as compared with the baseline (P <0.05), but with no statistically significant difference at different postoperative months (P >0.05). The intraoperative blood loss was less in the LSEP than in the LSTR group (［8.3 ± 5.2］ vs ［9.1 ± 6.1］ ml, P >0.05), the operation time was shorter in the former than in the latter (［38.27 ± 9.23］ vs ［43.46 ± 11.72］ min, P >0.05), and so was the time of gastrointestinal function recovery (［1.27 ± 0.26］ vs ［2.43 ± 0.41］ d, P <0.05). No statistically significant differences were observed between the two groups during the 6- to 18-month follow-up in the rates of postoperative subcutaneous hematoma, scrotal and subcutaneous emphysema, recurrence, or pregnancy (P >0.05). CONCLUSIONS Laparoscopic extraperitoneal high ligation of the spermatic vein is safe and effective and has the advantage of quick recovery in the treatment of varicocele.

ObjectiveTo compare the clinical effect of transumbilical single-port laparoscopy combined with improved double hernia needles with that of traditional open surgery in the treatment of hydrocele in children.

METHODSWe retrospectively analyzed 35 cases (54 sides) of pediatric hydrocele treated by transumbilical single-port laparoscopy combined with improved double hernia needles (laparoscopy group). We recorded the operation time, intraoperative blood loss, hospital stay, scrotal edema, and postoperative complications and compared them with those of another 46 cases (58 sides) treated by traditional open surgery (open surgery group) during the same period.

RESULTSThe laparoscopy group showed a significantly shorter operation time, less intraoperative blood loss, milder scrotal edema, and fewer hospital days than the open surgery group (all P<0.05). However, no statistically significant difference was found in the incidence of postoperative complications between the two groups (P>0.05). Subcutaneous emphysema developed in 2 patients in the laparoscopy group, which disappeared after 1－3 days of oxygen inhalation and other symptomatic treatment, while scrotal hematoma occurred in 1 and incision fat liquefaction in 2 patients in the open surgery group 3 days postoperatively, which healed after debridement suture and daily dressing, respectively. The patients were followed up for 3－6 months, which revealed no late complications in the laparoscopy group but 1 case of unilateral recurrence and 2 cases of offside recurrence in the open surgery group, all cured by laparoscopic internal ring ligation.

CONCLUSIONSTransumbilical single-port laparoscopy combined with improved double hernia needles is superior to traditional open surgery for the treatment of pediatric hydrocele and therefore deserves clinical generalization.

PURPOSE: Spontaneous pneumomediastinum (SPM) is a rare entity, with only a few cases reported, especially in adolescents. We aimed to analyze the clinical characteristics of SPM in adolescents and the diagnostic implications of computed tomography (CT) and esophagography therein. MATERIALS AND METHODS: This retrospective descriptive study was conducted as a review of medical records of 416 adolescents (10-18 years of age) with chest pain from March 2005 to June 2013. Information on clinical presentation, methods of diagnosis, hospital stay, and outcomes were collected and analyzed. RESULTS: Among adolescents complaining of chest pain, 11 patients had SPM (11/416, 2.64%). All patients presented with pleuritic chest pain, and 54.5% reported neck pain as the most common associated complaint. Clinical findings were nonspecific, and initial chest X-ray assessment was diagnostic only in three of 11 patients. However, reassessment of chest X-ray revealed diagnostic findings of SPM in five of the remaining eight patients. CT was diagnostic in all patients, while esophagography and echocardiogram were uninformative. Symptomatic improvement was noted within 2.45+/-1.2 hours (range, 0.5 to 4) after supportive care; mean hospital stay was 4.54+/-0.99 days (range, 2 to 6). No recurrence was observed. CONCLUSION: SPM is a rare disease that should be considered in adolescent patients with pleuritic chest pain. Careful reading of initial chest X-rays is important to avoiding further unnecessary investigations. SPM is self-limited and treatment is supportive; nevertheless, if there are no indications of esophageal rupture, urgent esophagography is not recommended.

BACKGROUND/AIMS: Acute exacerbations in chronic obstructive pulmonary disease may be related to air pollution, of which ozone is an important constituent. In this study, we investigated the protein profiles associated with ozone-induced exacerbations in a smoking-induced emphysema model. METHODS: Mice were divided into the following groups: group I, no smoking and no ozone (NS + NO); group II, no smoking and ozone (NS + O); group III, smoking and no ozone (S + NO); and group IV, smoking and ozone (S + O). Bronchoalveolar lavage, the mean linear intercept (MLI) on hematoxylin and eosin staining, nano-liquid chromatography-tandem mass spectrometry (LC-MS/MS), and Western blotting analyses were performed. RESULTS: The MLIs of groups III (S + NO) and IV (S + O) (45 +/- 2 and 44 +/- 3 microm, respectively) were significantly higher than those of groups I (NS + NO) and II (NS + O) (26 +/- 2 and 23 +/- 2 microm, respectively; p < 0.05). Fourteen spots that showed significantly different intensities on image analyses of two-dimensional (2D) protein electrophoresis in group I (NS + NO) were identified by LC-MS/MS. The levels of six proteins were higher in group IV (S + O). The levels of vimentin, lactate dehydrogenase A, and triose phosphate isomerase were decreased by both smoking and ozone treatment in Western blotting and proteomic analyses. In contrast, TBC1 domain family 5 (TBC1D5) and lamin A were increased by both smoking and ozone treatment. CONCLUSIONS: TBC1D5 could be a biomarker of ozone-induced lung injury in emphysema.

BACKGROUNDCombined emphysema and pulmonary fibrosis, including idiopathic pulmonary fibrosis (IPF), is a distinct disorder described with upper-lobe emphysema and lower-lobe fibrosis on chest computed tomography. Smoking appears to be the predominant risk factor for this disorder. We aimed to compare clinical features, smoking history, physiological and radiological findings between IPF with and without emphysema.

METHODSA sample of 125 IPF patients over a period of 48 months were evaluated. High resolution CT scans were reviewed blinded to clinical data. The IPF patients with or without emphysema were classified accordingly.

RESULTSThe prevalence of emphysema in this IPF sample was 70/125. IPF with emphysema was significantly associated with smoking status (OR 63; 95% CI 4.4 to 915; P = 0.002) and smoking pack year (OR 1.1; 95% CI 1.05 to 1.13; P = 0.000). The patients with IPF and emphysema had a higher decrease in carbon monoxide diffusing capacity adjusted for alveolar volume ((58±19)% pred vs. (66±21)% pred; P = 0.021) and a higher prevalence of pulmonary hypertension (24/70 vs. 7/55; P = 0.006). The two groups of patients had similar forced and residual volumes. No significant differences were found in cell differentials of bronchoalveolar lavage or the scores of fibrosis on chest CT. Survival of the patients with emphysema was significantly less than that of patients with IPF alone.

CONCLUSIONSCigarette smoking induces IPF combined with emphysema. Emphysema further impairs physiological function and increases the prevalence of pulmonary hypertension that leads to poor prognosis. The inclusion of the patients with combined pulmonary fibrosis and emphysema in IPF clinical trials may lead to under evaluation of the effect of treatment in patients.

OBJECTIVETo analyze the diagnosis, treatment and prognosis of spontaneous pneumomediastinum (SPM) in children.

METHODA retrospective analysis of the clinical data of 18 children diagnosed with SPM in Yuying Children's Hospital Affiliated to Wenzhou Medical University from December 2007 to February 2013 was performed. Information of the sequelae and recurrence of SPM was obtained by telephone follow-up. SPM was diagnosed according to Versteegh's standard. SPM cases due to mechanical ventilation, trauma, inhaled foreign body or as a result of the underlying disease were not included. Also cases of secondary pneumothorax pneumomediastinum and neonatal mediastinal emphysema were excluded.

RESULTFifteen of 18 cases were boys and 3 were girls, the range of age was from 9 to 17 years. Predisposing factors included sport activities, severe cough or without a known cause. Clinical manifestations included chest pain, chest tightness, dyspnea, neck pain, back pain, foreign body sensation or pain on swallowing, throat pain of swelling. Chest CT of 18 cases showed pneumomediastinum, 8 cases displayed varied degrees of air in neck, chest; 18 cases of SPM responded well to bed rest, oxygen, antitussive and anti-infection treatment. Fifteen cases received chest CT or X-ray inspection after therapy, showing that the pneumomediastinum disappeared or significantly absorbed, 3 cases improved in clinical symptom. Among 18 patients, telephone follow-up of 14 were successful and 4 cases were lost. An average follow-up time was (24 ± 17) months. None of the cases had any serious consequences, and recurrence happened in one case.

CONCLUSIONChildren's spontaneous pneumomediastinum is a benign disease. When a child has chest pain or chest tightness, SPM should be considered after excluding the common diseases. SPM can be diagnosed in association with clinical feature and chest CT examination. Patients respond well to conservative therapy and most of them had no severe sequelae.

BACKGROUNDThe condition of concomitant upper lobe emphysema and lower lobe fibrosis as identified by computer tomography is known as combined pulmonary fibrosis and emphysema (CPFE). CPFE has distinct clinical characteristics compared with emphysema alone (EA) and idiopathic pulmonary fibrosis (IPF) without emphysema. However, the pulmonary inflammation characteristics of CPFE are not well known, and the differences between CPFE and the other two diseases with regards to pulmonary inflammation need to be explored. The pulmonary inflammatory characteristics were investigated in CPFE patients and compared with EA and IPF.

METHODSFraction exhaled nitric oxide (Fe,NO) and differential cell counts, the concentrations of monokine induced by interferon gamma (MIG/CXCL9), interferon-inducible protein 10 (IP-10/CXCL10), and interferon-inducible T cell alpha chemoattractant (I-TAC/CXCL11) were measured in induced sputum obtained from subjects with CPFE (n = 22), EA (n = 22), IPF (n = 14), and healthy volunteers (HV, n = 12). In addition, immunohistochemistry was used to quantify the expression of nitric oxide synthases in alveolar macrophages in 23 lung tissues from patients and control subjects.

RESULTSThe CPFE group had higher alveolar NO than subjects in the EA and HV groups (P = 0.009, P = 0.001, respectively) but not than the IPF group (P > 0.05). Numbers of sputum eosinophils were significantly elevated in CPFE and IPF groups compared with the HV group (P = 0.001, P = 0.008). In contrast, eosinophil counts in EA group did not differ from those in the HV group. Compared with the EA and HV groups, the CPFE group had a lower concentration of I-TAC/CXCL11 in sputum supernatants (P = 0.003, P = 0.004). Immunoreactivity for inducible nitric oxide synthase (iNOS) was higher in the CPFE group than in the EA group (P = 0.018, P = 0.006, respectively).

CONCLUSIONSThe pulmonary inflammation of CPFE group is more similar to IPF group, while the distal airway inflammation is more significant in CPFE and IPF groups than in EA group. Lung eosinophil cell infiltration and high NOS expression in alveolar macrophage might participate in this pathogenesis.
