One hundred and five hepatic resection were performed from 1984 to 1994. Six of these patients complicated with subphrenic infection after hepatectomy, of whom two patients died of liver failure. Subphrenic dropsy occureeed in nine cases. Subphrenic infection is easy to occur in: right or extend lobectomy, massive blood loss at operation, and in postoperative bleeding which subjects to laparotomy for lemostasis. Seecure hemostasis, avoidence of hepatic tissue devitalization during operation and effective subphenic drainage aree essential to reduce the incidencee of subphrenic infection, and routine bacterial culture of subphrenic drainage fluid will help to select propre antibiotic.
To investigate the method of using vacuum seal ing drainage (VSD) technique to repair the wound of the injured in Wenchuan earthquake and its therapeutic effect. Methods From May 12, 2008 to June 12, 2008, 52 injured persons (83 wounds) were treated, including 27 males and 25 females aged 11-83 years old (average 42 years old). There were 22 cases of crush injury, 9 cases of contusion and laceration injury, 17 cases of compression injury receiving incision decompression of fascia compartment and 4 cases of open amputation. And 37 wounds were on the leg, 13 woundson the thigh, 17 wounds on the forearm, 11 wounds on the upper arm and 5 wounds on the trunk. The wound ranged from3 cm × 2 cm to 30 cm × 15 cm, and the time from injury to undergoing VSD treatment was 12 hours-18 days. After complete debridement, the wound was covered by VSD dressing, and antibiotics were given according to the result of drug sensitive test. When wound infection was under control and granulation tissues grew well, the method of either direct suture or skin grafting or flap transposition was used to repair the wounds. Results In 21 cases (40.4%), wound secretion smear was positive, and multiple species of bacteria were detected, such as staphylococcus aureus, escherichia col i, proteus and klebsiella pneumoniae. After initial operation, 7 injured persons were transferred to the hospital outside of Sichuan province for further treatment. VSD treatment was performed on 33 cases (45 wounds) once, 6 cases (10 wounds) twice, 2 cases (3 wounds) three times and 1 case (1 wound) four times, resulting in the control of wound infection and the growth of granulation tissue. Then the wounds were repaired by either direct suture or skin grafting or flap transposition. Three cases (4 wounds) underwent VSD treatment ten times, leading to the control of infection and the stabil ity of condition. Conclusion VSD treatment can cover the wound promptly, el iminate contamination, prevent secondary infection and benefit late-stage wound repair. During the process of treatment, no medical necessity for frequent change of dressing can rel ieve the pain suffered by the injured and decrease theworkload of medical stuff, thus facil itating the rescue work.
Objective To investigate the etiology, pathogenesis, clinical manifestations, diagnosis and treatment of acute obstructive suppurative pancreatic ductitis (AOSPD). Method The literature reports on AOSPD at home and abroad were reviewed and analyzed comprehensively based on clinical experience. Results AOSPD was a rare clinically infectious disease of purulent pancreatic duct. Chronic pancreatitis and ampullary operations were the main pathogenesis factors. The clinical symptoms were non-specific, and the imaging manifestations were pancreatic duct dilatation and pancreatic duct calculi. The clinical diagnosis was mainly determined by epigastrium CT or endoscopic retrograde cholangiopancreatography, which was easy to be misdiagnosed and missed. Conclusion The clinical diagnosis of AOSPD is difficult, early pancreatic duct drainage is the key to the treatment, and attention should be paid to its diagnosis and treatment.
Objective To evaluate the effect of ultrasound guided percutaneous drainage on acute perforation of gastroduodenal ulcer in elderly patients. Methods The clinical features, treatments, and the curative effects of 86 elderly cases (≥65 years) of acute perforation of gastroduodenal ulcer in our hospital between January 2004 and October 2009 were retrospectively analyzed. Twenty-one cases were treated by ultrasound guided percutaneous drainage (drainage group), and 65 cases were treated by exploring operation (operation group). Results Drainage group was cured and had no complications. In 15 patients which accepted recheck one month after drainage, gastroscope showed the ulcer healed in 12 cases， and improved in 3 cases. In operation group, 63 cases were cured and 2 cases died. Compared with the drainage group, there was no significant difference in cure rate (Pgt;0.05). However, 11 patients had operative complications in operation group, which was significantly more than that in the drainage group （Plt;0.05）. In 45 patients which accepted recheck one month after operation, gastroscope showed the ulcer healed in 38 cases， and improved in 7 cases. Conclusion For elderly patients with acute perforation of gastroduodenal ulcer， if the patients do not fit for exploring operation， ultrasound guided percutaneous drainage is proved to be a simple, safe, and effective means.
ObjectiveTo investigate the anatomical characteristics of breast lymphatic drainage in patients with breast cancer after injecting methylene blue and indocyanine green (ICG) into the intradermis of the areola.MethodsOne hundred and eighty-six patients with stage 0–Ⅱ breast cancer were collected. The sentinel lymph node (SLN) biopsy was performed by injecting methylene blue and ICG. At the same time, the number of sentinel lymphatic channel (SLC), origin angle, direction, and consistency were also studied.ResultsA total of 308 SLCs were successfully showed in the 186 patients and 679 SLNs were detected. The 95.8% (295/308) of SLCs and 93.1% (632/679) of SLNs were showed by combination in the methylene blue and ICG. The 46.8% (87/186) of patients had 1 SLC, the 40.9% (76/186) of patients had 2 SLCs, the 12.4% (23/186) of patients had 3 SLCs. The 82.8% (255/308) of SLCs flowed from the outer upper edge of the areola, the 3.2% (10/308) of SLCs flowed from the outer lower edge of the areola, the 14.0% (43/308) of SLCs flowed from the inner upper edge of the areola. The 89.9% (277/308) of the SLCs flowed mainly through the 0°—60° interval in the outer upper quadrant, 10.1% (31/308) of the SLCs flowed through the 61°—90° interval in the outer upper quadrant.ConclusionsThe consistency of SLC and SLN stained by the two tracers is good. The number of SLC is 1–3. The SLCs flow mainly through the 0°—60° interval in the outer upper quadrant of the breast, then flow into in the axilla and don’t flow into the internal mammary lymph nodes. The deep superficial lymphatic channels under the skin and the penetrating lymphatic channels can not be showed by ICG, but the SLN can be showed by it.
ObjectiveTo investigate the effect of multi-sided foramen ultrafine drainage tube with metal support on the formation of thoracic residual cavity after uniportal video-assisted thoracoscopic (VATS) upper lobectomy. MethodsThe clinical data of the patients who underwent uniportal VATS upper lobectomy for lung cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2021 to April 2022 were retrospectively analyzed. According to the type of ultrafine drainage tube used in the surgery, the patients were divided into a test group (using metal-supported multi-sided foramen ultrafine drainage tube) and a control group (using ordinary 12F ultrafine drainage tube). The incidence of postoperative thoracic residual cavity and operation-related data were compared between the two groups. ResultsA total of 200 patients were enrolled, including 126 males and 74 females, with a mean age of 57.52 years. There were 90 patients in the test group, and 110 patients in the control group. The incidence of postoperative thoracic residual cavity in the test group was lower than that in the control group (P=0.045). The differences in the postoperative bedtime, postoperative visual analogue scale, postoperative analgesic pump using time, postoperative hospitalization time, times of postoperative thoracentration and drainage, postoperative drainage time and hospitalization cost between the two groups were statistically significant (P<0.05). The incidences of postoperative lung infection, pleural effusion and atelectasis complications were lower in the test group than those in the control group (P<0.05). The differences in the preoperative anesthesia time, operation time, intraoperative bleeding and postoperative lung leakage were not statistically significant (P>0.05). ConclusionThe use of multi-sided foramen ultrafine drainage tube with metal support can reduce the incidence of thoracic residual cavity after uniportal VATS upper lobectomy, and can reduce pain and economical burdens and the incidence of operation-related complications, accelerating the recovery of patients after surgery. The application of multi-sided foramen ultrafine drainage tube with metal support in uniportal VATS upper lobectomy can be widely used in the clinic.

The included literature was evaluated for quality and integrated into evidence. Results A total of 9 articles were included, including 3 guidelines, 1 evidence summary, 1 expert consensus, 1 systematic review, and 3 original studies. A total of 30 pieces of evidence were formed, covering six aspects: risk management, catheter placement, catheter maintenance, extubation, diagnosis and treatment of intracranial infections, education and training. ConclusionsThe prevention and management of LD-related intracranial infections involve multiple pieces of evidence, and medical staff should selectively apply the best evidence based on patient and clinical conditions to reduce the incidence of intracranial infections and improve medical quality.
Objective To evaluate outcomes of vacuum sealing drainage（VSD）for the treatment of wound infection after cardiac surgery.?Methods?We retrospectively analyzed clinical data of 70 patients（with valvular heart disease，congenital heart disease or coronary heart disease）who underwent cardiac surgery via mid-sternotomy and had postoperative wound infection from Jan. 2008 to Jan. 2012 in General Military Hospital of Guangzhou Command. According to different treatment strategy for wound infection, all the patients with wound infection （incision longer than 5 cm） were randomly divided into VSD group （n=35） and control group（n=35） by random number table，while VSD treatment was used for patients in VSD group and routine treatment was used for patients in control group. Treatment outcome，duration of wound infection, duration of antibiotic treatment and treatment cost were compared between the two groups.?Results?There was no in-hospital death in both groups. Wound exudate significantly decreased and fresh granulation tissue grew well in the wound in most VSD group patients after VSD treatment. The cure rate of VSD group was significantly higher than that of control group （94.3% vs. 60.0%，P＜0.05）. Duration of wound infection （12.9±3.4 d vs. 14.8±4.1 d；t=-2.094，P=0.040）and duration of antibiotic treatment （7.0±1.5 d vs. 8.3±1.9 d；t=-2.920，P=0.005） of VSD group were significantly shorter than those of control group. There was no statistical difference in treatment cost between the two groups. Fifteen patients in VSD group were followed up （42.9%） for 3 months with good wound healing, and 20 patients in VSD group were lost in follow-up.?Conclusion?VSD is effective for the treatment of wound infection after cardiac surgery with shortened treatment duration and similar treatment cost compared with routine treatment.
Objective To review the clinical applications of functional perforator flaps in restoring human body functions. Methods An extensive literature review was conducted on both domestic and international publications to summarize the clinical use of functional perforator flaps for functional restoration. Results Perforator flaps are among the most commonly used flaps in reconstructive surgery. Beyond providing soft tissue repair, they are increasingly employed to reconstruct diverse bodily functions, leading us to propose the concept of the “functional perforator flap”. Although various forms of functional perforator flaps are currently utilized, reports are predominantly scattered case studies, lacking systematic organization. Commonly used functional perforator flaps can be categorized into five types: chimeric perforator flaps, perforator flaps for nerve function restoration, perforator flaps for lymphatic drainage enhancement, flow-through perforator flaps, and perforator flaps for restoring bone and joint motion. These flaps significantly broaden the application scope of perforator flaps, elevating the goal of reconstruction from mere wound repair to achieving repair concurrent with functional reconstruction. ConclusionThe application of various functional perforator flap designs significantly improves wound reconstruction outcomes and represents an effective approach for managing complex defects. Future developments will undoubtedly see more forms of functional perforator flaps reported to meet increasingly sophisticated reconstructive demands.
ObjectiveTo explore the clinical significance of detecting serum intact parathyroid hormone (iPTH) and drainage fluid parathyroid hormone (dPTH) after thyroidectomy in forecasting parathyroid function.MethodsThe clinical data of 95 thyroidectomy patients in the same treatment group from March 2018 to September 2018 were retrospectively analyzed, which in the Department of Thyroid-Breast Surgery, the Second Affiliated Hospital of Kunming Medical University. According to the surgical method, the patients were divided into 3 groups: isthmus and unilateral thyroidectomy (partial resection group, n=33), total thyroidectomy (total resection group, n=33) and total thyroidectomy and central lymph node excision (radical resection group, n=29). The negative pressure drainage tube was placed in the operative area. The iPTH and serum calcium were detected before and the first day after operation. The dPTH was detected in the first day and the second day after operation. Serum calcium, iPTH and dPTH were statistically analyzed.ResultsThere were no significant differences in operative time, hospital stay and blood loss between the total resection group and the radical resection group (P>0.05), but the partial resection group were all less than the other two groups (P<0.01). On the first day after operation, the iPTH in the three groups were lower than that before operation, and the iPTH was significantly decreased in the total resection group and the radical resection group, with statistically significant difference (P<0.05). The dPTH in the three groups were significantly increased on the first and second day after operation (P<0.05), but there was no statistically significant difference between the three groups (P>0.05). There was no statistically significant difference in serum calcium between the three groups on the first day after operation (P>0.05).ConclusionsThe levels of iPTH, dPTH and serum calcium after thyroidectomy can comprehensively forecast the parathyroid function. Preventive calcium supplementation can reduce the occurrence of postoperative symptomatic hypocalcemia, which is conducive to the recovery of parathyroid function.
