ObjectiveTo investigate the relationship between preoperative C-reactive protein (CRP)/albumin ratio (CAR) and National Institutes of Health (NIH) risk classification in patients with gastric stromal tumors.MethodsClinical data of 108 patients with gastric stromal tumors admitted to the First Affiliated Hospital of Kunming Medical University from February 2010 to November 2016 were retrospectively collected. With the median of CAR as the critical value, patients were divided into high CAR group (CAR>0.048) and low CAR group (CAR≤0.048). Then observed the general clinicopathological characteristics and survival status of patients with higher and lower CAR value.ResultsThere were significant differences in NIH classification, tumor diameter, and mitosis between the high CAR group and low CAR group (P<0.05). Compared with the low CAR group, the tumors in the high CAR group had larger diameter, higher mitotic figure, and higher NIH grade. Survival analysis showed that the prognosis of the low CAR group was better than that of the high CAR group (χ2=15.152, P<0.001).ConclusionsCAR is closely related to the malignant index and NIH risk classification of gastric stromal tumors. It can be used as an index for evaluating the malignant degree of gastric stromal tumors, and it is expected to be an important reference factor for clinical NIH risk classification and prognosis.
ObjectiveTo study the efficacy, the operation skills, and the complications of laparoscopic totally extraperitoneal prosthesis (TEP). MethodsThe clinical data of 1 020 patients received TEP from April 2011 to March 2014 were retrospectively analyzed. The oral feeding time, out of bet time, operation time, hospital stay, hospitalization costs, postoperative complications, and so on were recorded. ResultsAmong the 1 020 patients, the types of hernias were 810 indirect inguinal hernias (including unilateral hernia and bilateral hernia), 118 direct inguinal hernias, 24 femoral hernias, and 68 recurrent inguinal hernias. The surgeries were basically successfully completed in all the patients, including 12 cases (both recurrent hernia) of conversion to laparoscopic transabdominal preperitoneal prosthesis (TAPP). All the patients could take food in a day and get out of bed on day 1 after operation. The unilateral operation time was (48±9.8) min, bilateral was (65±8.6) min. The postoperative hospital stay was 0.5-2.0 d, total hospital stay was (3.48±2.40) d, hospitalization costs was (8 958±1 685) yuan. Main complication was 61 (5.98%) cases of seroma, 48 (4.70%) cases of temporary nerve paresthesia, 23 (2.78%) cases of urinary retention, 9 (0.88%) cases of chronic pain, and 5 (0.49%) cases of abdominal artery injury. No incision infection, visceral injury, small intestinal obstruction, and other serious complications happened. No occurrence occurred with following-up for 1 year. Classification of different hernia complications, the statistical analysis showed that the total incidence of complications of the typeⅣwas highest, then which was in sequence of typeⅢ, typeⅡ, typeⅠ(P < 0.001). ConclusionLaparoscopic TEP is a safe, reasonable repair without tension with small incision, lighter abdominal interference, less pain, early return to normal activities, but it is a difficult technology and has a higher cost.
