【Objective】 To investigate the efficacy and safety of double-sheath vacuum suction microchannel percutaneous nephrolithotomy (MPCNL) in the treatment of complex renal stones. 【Methods】 The clinical data of 139 patients with complicated renal stones who received MPCNL during Aug. 2019 and Jul.2020 were retrospectively analyzed. According to the operation modes, the patients were divided into the double-sheath vacuum suction group (dsVS group, n=72) and conventional nephrostomy sheath group (cNS group, n=67). The perioperative indexes and the first-stage stone clearance rate of the two groups were compared. 【Results】 In the dsVS group and cNS group, the mean operation time was (46.72±9.55) min and (57.22±11.31) min, respectively (P<0.05). The first-stage stone clearance rate was 83.33% and 70.15%, respectively (P<0.05). The BUN value was (5.07±1.65) mmol/L and (5.75±1.83) mmol/L, respectively (P<0.05). The WBC value was (9.45±2.46)×109/L and (10.71±3.14)×109/L, respectively (P<0.05). The incidence of postoperative fever was 1.39% and 11.94%, respectively (P<0.05). There was no significant difference in other clinical data between the two groups (P>0.05). 【Conclusion】 The double-sheath vacuum suction MPCNL is safe and effective to manage complex renal stones, which can shorten the operation time, reduce postoperative complications, and improve the stone clearance rate.

Use of Vacuum-suction in Depressed Skull Fractures ­ Case Report and Technical Nuances of Nonoperative Treatment

Up to 20% of victims from skull fractures are represented by the pediatric population, and 50% of these lesions are depressed skull fractures. The treatment is multimodal in nature, ranging from conservative treatment to open surgical repair. The last one is associated, although in a small proportion, to complications, such as infections, hematomas and even death, besides the risks of the anesthetic procedure itself. The authors of the present article present a case report of the successful treatment of a depressed skull fracture in a newborn patient, using the vacuum-suction technique. The use of vacuum-suction may be beneficial for the pediatric patients, as it is a quick, non-invasive procedure, without the need for general anesthesia.

Role of subcutaneous vacuum suction drain in prevention of abdominal wound complication in emergency laparotomy

Background: Some of the most common wound complications following laparotomy include hematoma formation, seroma formation, wound infection, burst abdomen and wound dehiscence. Closed-suction drains (CSDs) help to drain any wound collection and also reduce any dead space in the wound thereby promoting healing and preventing complication.Methods: We conducted a prospective study and included patients presenting with acute abdomen in emergency department. Patients were selected as per inclusion and exclusion criteria. Two groups (group A and B) with equal number of patients were created based on closed envelope technique. CSD was placed in the wound of patients in group A. Wound healing and complications were compared between the two groups.Results: 50 patients were included in the study with 25 in each group. Hematoma formation was found to be significantly more among group B (24.0%) compared to group A (4.0%). Seroma formation (p value =0.03917), SSI rate (p value =0.039) and wound dehiscence/burst abdomen (p value =0.0415) was more in group B than group A. The mean wound healing time (days) and mean hospital stay (days) was significantly more in group B.Conclusions: Placing a subcutaneous vacuum suction drain at the time of abdominal wall closure during emergency laparotomy results in better wound healing and reduces postoperative wound complication, hospital stay time, morbidity and also decreases overall healthcare cost.
