Objective To explore the relationship between the HBsAg positive patients suffering from hepatocellular carcinoma (HCC) and HBV DNA genotype. Methods By using PCR type-specific primers combined with sequencing of genotype, we analyzed the genotype of HBV DNA in the serum of 500 patients with positive HBsAg in our hospital. Among them, 150 cases suffered from HCC. Results Genotype B and C were both predominant genotypes in HBsAg positive patients. But in HCC group, the rate of genotype C was 65.33% （98/150）, which was significantly higher than that in non-HCC group (88/350, 25.14%), while genotype B, in contrast, was 28.67% （43/150） and 68.86% （241/350）， χ2=75.45， Plt;0.05. The distribution of HBV DNA genotype B or genotype C in different gender or different age groups were not statistically significantly different in cases of HCC (Pgt;0.05). Conclusion Genotype C of HBV DNA is more common in patients with HCC, and maybe there is relationship between genotype C and the occurrence of HCC.
ObjectiveTo explore the clinical efficacy and experience of laparoscopic partial splenectomy. MethodsThe clinical data of 11 cases of splenic space occupying lesions in the author's hospital from January 2011 to May 2014 were retrospectively analyzed. Laparoscopic partial splenectomy were carried out in 11 patients. ResultsEleven patients were successfully completed the laparoscopic partial resection of spleen. Operative timewas 2.0-3.5 h, the average operative time was (2.5±0.3) h. Intraoperative blood loss was 155-320 mL, the average blood loss was (200.3±55.1) mL. Eleven patients who ride smoothly, there was no case of pancreatic injury, gastrointestinal injury, major bleeding and other complications. Postoperative patients recovered well, 24 h after operation gastrointestinal function recovery, and can get out of bed activities. Silicone drainage tube placement time was 3-5 d, the average for placing time was (4.0±1.3) d. about 60-100 mL, the average (70.3±15.8) mL. The average length in hospital was 5-8 d, patients with an average of (6.3±1.5) d, all of the patients without postoperative complications such as infection, splenic infarction. Postoperative pathologic results suggested 6 cases were spleen hemangioma, 3 cases were pseudocyst of spleen, and 2 cases were true epithelial cyst. Conciusions Laparoscopic partial spleen resection should fully grasp the operative indication, fully understand the pathological changes and the structure of door of the spleen, in earnest and patient, under the operation of laparoscopic spleen resection is safe, feasible, and the clinical curative effect is satisfied, worthy of clinical popularization and application.
ObjectiveTo explore the feasibility and characteristics of three-port laparoscopic cholecystectomy (LC) in the treatment of cholecystitis with gallbladder calculi incarceration. MethodsThe clinical data of 160 patients with gallbladder calculi incarceration treated by three-port LC between July 2010 and December 2014 were analyzed retrospectively. Among the patients, there were 104 cases of calculi incarcerated in the gallbladder neck area, 20 cases in the cystic gall duct, and 36 cases in the gallbladder ampullar region. Elective operations were carried out for 120 patients and 40 underwent emergency operation. ResultsThree-port LC was successfully completed in 154 patients (96.25%), and the other 6 patients were converted to open surgery among whom 2 underwent elective operation (1.67%) and 4 underwent emergency operation (10.00%). Two converted patients in the elective operation group had Mirizzi syndrome and gallbladder carcinoma respectively; all the 4 converted patients in the emergency operation group had a disease course of about one week with compacted triangle structure and gallbladder edema thickening of 1.0 cm, causing difficult separation under laparoscope. Seventy patients had varying degrees of enlargement and edema of gallbladder, 60 had varying degrees of gallbladder atrophy, and 30 had almost normal gallbladder. There were 80 cases of dark green thick bile, 10 of purulent bile, 40 of white bile, and 30 of empty gallbladder and no bile. No complications were found during the follow-up of 6 to 36 months, except that one patient was found to have secondary common bile duct stones three months after discharge, and the patient was cured by endoscopic retrograde cholangiopancreatography. Conclusions Elective or emergency three-port LC is safe and feasible for gallbladder calculi incarceration as long as the operator had skilled technique and made the right decision on opportunity of conversion.
ObjectiveTo evaluate the safety and efficacy of unconventional abdominal drainage after laparoscopic hepatectomy.MethodsThe clinicopathologic data of patients who underwent laparoscopic hepatectomy for liver tumors in the Mianyang Central Hospital from June to December 2019 and met the inclusion criteria were retrospectively collected. Based on whether drainage tube was placed in the abdominal cavity during operation, the patients were divided into non-catheterized group (without drainage tube) and catheterized group (with drainage tube). The intraoperative data and postoperative complications (e.g. intraabdominal hemorrhage, bile leakage, abdominal infection, and liver failure) were compared between the two groups. Then, the intraoperative data and postoperative conditions of liver cancer and non-liver cancer patients with or without abdominal drainage tube were compared and analyzed.ResultsA total of 117 eligible patients were included in the study. The non-catheterized group had 59 patients and the catheterized group had 58 patients. The patients with liver cancer had 84 patients (44 non-catheterized patients and 40 catheterized patients) and the patients without liver cancer had 33 patients (15 non-catheterized patients and 18 catheterized patients). ① On the whole, the groups were comparable in the baseline data between the non-catheterized group and the catheterized group, such as gender, age, HBV infection, body mass index, hepatic function index, liver stiffness value, disease category, etc. (P>0.05). Compared with the catheterized group, the non-catheterized group had earlier off-bed activities and earlier flatus time (P<0.001), and shorter postoperative hospital stay (P=0.030). However, no statistically significant differences were found in other indicators between the two groups (P>0.05). ② Whether the patients had liver cancer or not, the non-catheterized patients still had earlier off-bed activities and earlier flatus time as compared with the catheterized patients (P<0.001). Among the patients with liver cancer, no difference was found in postoperative hospital stay. However, among the patients without liver cancer, the non-catheterized patients had shorter postoperative hospital stay than the catheterized patients (P=0.042). No statistically significant differences were found in other indicators between the catheterized patients and non-catheterized patients (P>0.05).ConclusionFor technologically skilled laparoscopic hepatectomy center, selectively not placing peritoneal drainage tube after surgery might better promote the health of patients.
ObjectiveTo explore the value liver resection combined with intraoperative radiofrequency ablation during the same period in the treatment of multiple liver cancer. MethodsWe retrospectively analyzed the clinical data of 33 patients with multiple liver cancer treated between January 2005 and April 2013. All the patients were treated by liver resection combined with intraoperative radiofrequency ablation in the same period. There were 91 tumor foci in 33 patients, among which 39 tumor foci were surgically removed, and 52 tumor foci were radiofrequency ablated. Ultrasonography and enhanced CT/MRI were performed for the patients 1 year, 2 years and 3 years after surgery. ResultsNo bleeding or death occurred during the operation. It was observed that the transient liver function was damaged after surgery, but it quickly returned to A level after treatment. All the patients had no perioperative death or other serious complications. Tumor recurrence rate was 16.1% in the first year, 48.4% in the second year and 93.5% in the third year after surgery. ConclusionLiver resection combined with intraoperative radiofrequency ablation for multiple liver cancer in the same period is feasible and safe, without increasing the average length of hospital stay, operative mortality rate and postoperative tumor recurrence rate.
ObjectiveTo investigate the prevention and control measures and procedures for surgical operation safety during the outbreak of new coronavirus pneumonia.MethodsAfter interpreting the diagnosis and treatment plan of new coronavirus pneumonia, the prevention and control plan of new coronavirus pneumonia, and the technical guidelines for prevention and control of new coronavirus pneumonia infection in medical institutions, we formulated and improved the prevention and control measures and procedures for surgical safety in our hospital.ResultsA total of 567 patients were operated in our hospital from January 22, 2020 to February 10, 2020, including 501 were operated in the surgical center and 66 were operated in the interventional center. Among all the cases, there were 303 emergency operation and 264 scheduled or limited operation. In the emergency operation, the top three were 130 cases of caesarean section (42.9%), 63 cases of abdominal digestive system operation (20.8%) and 31 cases of skull operation (10.2%). In the scheduled or limited operation, the top four were 65 cases of benign diseases of the eye (24.6%), 57 cases of tumor (21.6%), 53 cases of orthopedic surgery (20.1%), and 25 cases of coronary angiography (9.4%). All the patients were successfully completed the operation and recovered well after the operation. No serious surgical complications or infection-related complications occurred.ConclusionDuring the outbreak of new coronavirus pneumonia, surgery and epidemic prevention and control can be carried out by adjusting and optimizing measures and procedures.
Objective To compare the therapeutic effect of conventional discectomy, posterior lumbar interbody fusion (PLIF), and transforaminal lumbar interbody fusion (TLIF) on the recurrent lumbar disc protrusion (RLDP). Methods From January 2000 to January 2008, 65 patients with RLDP underwent different surgical procedures, namely conventional discectomy (group A, 25 cases), PLIF (group B, 22 cases), and TLIF (group C, 18 cases). There were 44 males and 21 females aged 26-65 years old (average 41 years old). All the patients were single-level protrusion, including 33 cases at the L4, 5 level and 32 cases at the L5, S1 level. The primary procedure included laminectomy discectomy in 39 patients, unilateral hemilaminectomy discectomy in 15 patients, and bilateral laminectomy and total laminectomy discectomy in 11patients. The recurrent time to the primary operation was 13-110 months (average 64 months). The location of recurrent disc protrusion was at the ipsilateral side in 47 cases and the contralateral side in 18 cases. No significant differences among three groups were evident in terms of basel ine data (P gt; 0.05). Results The incision all healed by first intention. The incidence of perioperative compl ication in group A (24.0%) and group B (22.3%) was significantly higher than that of group C (5.6%) (P lt; 0.05), and there was no significant difference between group A and group B (P gt; 0.05). The operation time and bleed loss during operation of group B were obviously higher than that of group A and group C (P lt; 0.05), and there was no significant difference between group A and group C (P gt; 0.05). There were no significant differences among three groups in terms of the length of hospital ization (P gt; 0.05). Six-one patients were followed up for 12-36 months (average 20 months). At 1 week after operation, the satisfied rate of patients was 84.0% in group A, 81.8% in group B, and 88.9% in group C (P gt; 0.05). All the patients in group B and group C achieved fusion uneventfully. There were no significant differences among three groups in terms of visual analogue scale (VAS) and Oswestry disabil ity index (ODI) when compared the preoperative value with the final follow-up value (P gt; 0.05). There was significant difference within group A, B, and C in terms of VAS and ODI when compared the preoperative value with the final follow-up value (P lt; 0.05), but there were no significant differences among three groups in the improvement rate (P gt; 0.05). The intervertebral space grading method proposed by Roberts et al. was adopted to evaluate the intervertebral space height (ISH), the preoperative value was 2.04 ± 0.93 in group A, 2.18 ± 0.91 in group B, and 2.11 ± 0.90 in group C, andat the final follow-up, the value was 2.64 ± 0.58 in group A, 1.05 ± 0.59 in group B, and 1.06 ± 0.42 in group C. There were significant differences among three groups in the ISH when compared the properative value with the final follow-up value (P lt; 0.05). Conclusion All of the three surgical procedures are effective for RLDP, but conventional discectomy and PLIF have more compl ications than TLIF. Conventional discectomy may result in the further narrow of the intervertebral space and the occurrence of segment instabil ity, whereas TLIF is safer, more effective, and one of the ideal methods to treat RLDP.
ObjectiveTo explore the effect of laparoscopic hepatectomy in patients with complex hepatolithiasis.MethodsThe clinical data of 31 patients with complex hepatolithiasis treated by laparoscopic hepatectomy in our hospital from January 2015 to September 2019 were retrospectively analyzed, and the effect was followed up.ResultsTwo cases were converted to open surgery, and the remaining 29 cases successfully completed laparoscopic surgery.
