ABSTRACT
Objective:To explore the risk factors of seroma after laparoscopic totally extraperitoneal hernia repair.Methods:The clinical data of 236 patients underwent laparoscopic totally extraperitoneal hernia repair from July 2018 to June 2021 in Jiaozhou Central Hospital of Qingdao City were retrospectively analyzed. The related risk factors of seroma after laparoscopic totally extraperitoneal hernia repair were analyzed.Results:Among 236 patients, the seroma occurred in 36 cases (seroma group), the incidence of seroma was 15.25%; no seroma occurred in 200 cases (non-seroma group). There were statistical differences in the duration of disease ≥5 years, scrotal hernia, internal inguinal ring defect ≥3 cm, rupture of hernia sac, experience of operators <5 years between 2 groups ( P<0.01 or <0.05); there were no statistical difference in age, body mass, type of patch, preoperative complications (including diabetes, chronic obstructive pulmonary disease and cardiac cerebrovascular disease) and operative time between 2 groups ( P>0.05). Multivariate Logistic regression analysis result showed that the duration of disease ≥5 years, scrotal hernia, rupture of hernia sac and experience of operators<5 years were independent influencing factors of seroma after laparoscopic totally extraperitoneal hernia repair ( OR = 5.147, 5.006, 0.044 and 3.315; 95% CI 1.513 to 17.516, 1.845 to 13.583, 0.008 to 0.240 and 1.029 to 10.679; P<0.01 or<0.05). Conclusions:The duration of disease ≥5 years, scrotal hernia, rupture of hernia sac and experience of operators<5 years are independent influencing factors of seroma after laparoscopic totally extraperitoneal hernia repair, and preoperative assessment of risk factors is helpful to reduce the incidence of seroma.
ABSTRACT
Objective To investigate the clinical guiding significance of lymphoscintigraphy with 99mTc-DX for radical lateral lymph node dissection with pelvic autonomic nerve preservation(PANP) in lower rectal cancer.Methods In 67 patients with pathologically proven lower rectal cancer,37MBq/0.8ml 99mTc-DX was injected into submucosa of the rectum through rectal endoscopy.At 0.5h,1h,2h,3h,4h,6h,12h,and 24h after the injection,the patients underwent pelvic and lower abdominal lymphoscintigraphy. The operative method was determined according to the imaging results,and the results of lymphoscintigrams were correlated with postoperative lateral node histologic examination.Results The scintigrams were postive in 37 cases,and all were unilateral.The positive patients underwent PANP.The image results were compared with histological lymph node examination in all patients operated upon for rectal cancer.Histologically,the cases in conformity were 26(70.3 %),false positive in 11 cases(29.7 %),and 2 of 30 false positive patients who demonstrated metastases to lateral node were operated by PANP,while the others underwent only PANP(type Ⅰ) without lateral lymph nodes dissection.The percentage of good sexual function of the two groups of cases after operation was 74.4 % and 71.4 % respentively.The percentages of mild dysuria and good function of urination were both 100 %.Conclusions Lymphoscintigraphy with 99mTC-DX has particular guiding significance in selection of PANP for lower rectal cancer.
ABSTRACT
Objective To investigate the early diagnosis, indications of operation, choice of operative procedure and effect of operation of closed injury of the duodenum . Methods The clinical data of 38 cases of closed injury of the duodenum treated in recent 11 years were retrospectively analysed . Results Thirty cases(78.9%) were diagnosed preoperatively, and 8 were misdiagnosed(21.1%). All of the 38 patients underwent surgical treatment. 36 cases(94.7%) were cured ,and 2 died(5.3%). Complications occurred in 9(23.7%) .Duodenal fistula was the main complication .Conclusions One must be alert to the possibility of injury of the duodenum in patients with closed upper abdominal injury. Early diagnosis, early operation and rational choice of surgical procedure are very important for the treatment of duodenal trauma.
