  • Risk factors associated with conversion to open surgery of laparoscopic repair for perforated peptic ulcer

    Objectives To analyze risk factors associated with conversion to open surgery of laparoscopic repair for perforated peptic ulcer. Methods From January 2009 to December 2014, 235 patients underwent laparoscopic repair for perforated peptic ulcer in the Chengdu 5th Hospital, were enrolled in this study. These patients were divided into laparoscopic repair group (n=207) and conversion to open surgery group (n=28). The characteristics, clinical outcomes, and prognosis factors were compared between these two groups. The receiver operating characteristic (ROC) curve was used to determine the critical cutoff value for diameter and duration of perforation for predicting conversion to open surgery. Results There were no significant differences of the age, gender, body mass index, comorbidity, history of ulcer, smoking history, history of nonsteroidal antiinflammatory drugs or steroids use, history of alcohol use, American Society of Anesthesiologists classification on admission, white blood cell count on admission, C reaction protein on admission, surgeons, suture method, and location of perforation between these two groups (P>0.05). The patients in the conversion to open surgery group had a higher procalcitonin (PCT) level on admission (P=0.040), longer duration of peroration (P<0.001), larger diameter of peroration (P<0.001), longer hospital stay (P=0.002), higher proportion of patients with Clavien-Dindo classification Ⅰ and Ⅱ (P<0.001), longer gastrointestinal function recovery time (P=0.003), longer analgesics use time (P<0.001), and longer off-bed time (P=0.001) as compared with the laparoscopic repair group. The results of logistic regression analysis showed that the peroration duration on admission〔OR: 2.104, 95%CI (1.124, 3.012),P=0.020〕and peroration diameter on admission〔OR: 2.475, 95%CI (1.341, 6.396),P=0.013〕were two predictors of conversion to open surgery. For the diameter of perforation, 8.0 mm was the critical cutoff value for predicting conversion to open surgery by ROC curve analysis, the sensitivity was 76%, the specificity was 93%, and the area under the curve (AUC) was 0.912. For the duration of perforation, 14 h was the critical cutoff value to predict conversion to open surgery, the sensitivity was 86%, the specificity was 71%, and theAUC was 0.909. Conclusions The preliminary results in this study show that diameter of perforation of 8 mm and duration of perforation of 14 h are two reliable risk factors associated with conversion to open surgery for perforated peptic ulcer. Also, PCT level would mightbe considered as a helpful risk factor for it.

  • Application of cervical expansion balloon in attempting vaginal delivery in pregnant women with cicatrical uter

    Objective To explore the safety and efficiency of cervical expansion balloon in promoting cervical ripening of cicatrical uter women with full-term pregnancy attempting vaginal delivery. Methods Fifty cases of pregnant women at the third trimester with cicatrical uter admitted to Nanshan District Maternal and Child Health Care Hospital of Shenzhen from July 2015 to March 2016 were retrospectively and randomly collected as the observation group. Another 50 pregnant women at the third trimester with normal uter admitted to the same hospital in the same period were retrospectively and randomly collected as the control group. All the cases had indications for labor induction, and had intention and conditions of vaginal delivery. Cervical expansion balloons were used in the two groups to promote cervical ripening. The effective rate of promoting cervical ripening, the outcomes of delivery and the incidences of adverse outcomes were compared between the two groups. Results The differences in effective rate of promoting cervical ripening and success rate of induced labor of cervical ripening of pregnant women between the observation group (66%, 76%) and the control group (76%, 84%) were not statistically significant (P>0.05). There were no significant differences in the time of birth process, amout of postpartum bleeding, birth immediate Apgar score, neonatal birth weight, and vaginal delivery rate, and the incidences of acute chorioamnionitis and cervical laceration of pregnant women between the two groups (P>0.05). Incomplete uterine rupture occurred in one case in the observation group, while none in the control group; neonatal mild asphyxia occurred in one case in the control group, while none in the observation group; the differences were not statistically significant (P>0.05). No postpartum hemorrhage occurred in the two groups. Conclusions Under the premise of strictly following the indications, cervical expansion balloon can be used in promoting cervical ripening at the third trimester of pregnant women with cicatrical uter attempting vaginal delivery, improve the success of attempting vaginal delivery, reduce the occurrence of reduplicated cesarean section, and not increase the incidence of maternal and fetal adverse outcomes.

  • Prognosis of pregnant patients with renal failure undergoing blood purification therapy

    Objective To observe the prognosis of pregnant patients with renal failure who underwent blood purification. Methods Pregnant patients with renal failure undergoing blood purification (hemodialysis or hemofiltration) from January 2009 to February 2017 were included in this study. Clinical data and pregnancy outcome were collected retrospectively. Results A total of 42 patients were enrolled in this study, including 38 with acute renal failure, 3 with chronic progressed renal failure, and 1 with chronic renal failure. There were 5 patients (11.9%) with chronic kidney disease (CKD) before pregnancy, 3 (7.2%) with systemic lupus erythematosus, 24 (54.8%) with hypertension, 5 (11.9%) with acute pancreatitis, and 7 (14.3%) with acute liver failure. In perinatal period, 7 patients (16.7%) died, whose underlying diseases were acute pancreatitis in 2, lupus nephritis in 1, acute hepatic failure in 3, and pulmonary tuberculosis breakout in 1. There were 5 patients with twin pregnancy, and 37 patients with single pregnancy. In the 28 patients with natural pregnancy ending, the live birth rate was 82.1% (23/28), and the live birth rate of twin pregnancy was only 50% (5/10). Twenty-seven patients were followed up, in whom 10 were in end stage of renal disease (ESRD), which was correlated with hypertension (P=0.001), and 3 patients were in CKD 1–4. Renal diseases were completely recovered in 14 patients. New CKD were diagnosed in 8 patients, without any correlated factor. Conclusions For pregnant patients with renal failure undergoing hemodialysis or hemofiltration, the death risk and the dead birth rate are high. Patients with hypertension or pre-existed renal failure have higher risk for ESRD. Some patients are not completely recovered from acute renal failure, with CKD left.

  • Internal medicine department management during surgical treatment of secondary hyperparathyroidism based on multiple disciplinary team

    ObjectiveTo investigate the role of multiple disciplinary team (MDT) during surgical treatment of renal secondary hyperparathyroidism (SHPT), and identify management points of Departments of Nephrology and Endocrinology.MethodsThe data of patients with chronic kidney disease undergoing surgical treatment for SHPT in West China Hospital of Sichuan University between January 2009 and December 2018 were retrospectively collected. We explained the surgical treatment of MDT in the management of renal SHPT, and compared the changes before and after the establishment of MDT.ResultsA total of 187 patients including 101 males and 86 females were enrolled, with an average age of (47.60±11.28) years old and median dialysis vintage of 7 years. Under MDT, the number of patients with parathyroidectomy increased [(8.50±5.10) vs. (59.50±2.12) patients/year, P<0.001] and the completion rate of preoperative examinations were greatly improved (P<0.001). The success rate of surgery was also increased (86.8% vs. 97.5%, P=0.010). Proportion of patients who were admitted to the Department of Nephrology was significantly increased (39.7% vs. 84.9%, P<0.001). Most patients after surgery were transferred to the Department of Endocrinology (5.9% vs. 77.3%, P<0.001) to manage postoperative complications and metabolic bone disease, and thus normalized the management of SHPT.ConclusionsThe MDT contributes to management of renal SHPT, which is worthy of popularization and spreading. The management of internal medicine departments during surgical treatment of SHPT based on MDT is important, because they can be helpful to complete preoperative examinations and preoperative preparation as well as to alleviate postoperative complications.

  • Revision of the perioperative recovery scale for integrative medicine based on item response theory

    ObjectiveThis study aimed to revise the perioperative recovery scale for integrative medicine (PRSIM) based on item response theory (IRT). MethodsUnder the guidance of IRT, a total of 349 patient data collected during the development of the original version of PRSIM at Guangdong Provincial Hospital of Chinese Medicine were used. Principal component analysis was performed using SPSS 18.0 software to test the unidimensionality. The R language was utilized for parameter estimation, including discrimination coefficient, difficulty parameters and information content, as well as drawing item characteristic curves to assess item quality and estimate item functioning differences. A comprehensive screening process was carried out by combining expert consultations, patient evaluations, and discussions within a core group. ResultsThe degree of discrimination of all items ranged from −0.535 to 2.195. The difficulty coefficient ranged from −10.343 to 5.461, and the average information content of all items ranged from 0.043 to 1.075. Based on the criteria for parameter selection, nine items were retained. The results of expert consultations indicated the removal of 5 items and the modification of 7 items. After discussion within the core group, a final decision was made to remove 5 items. ConclusionBased on a synthesis of IRT and expert consultation feedback, and following discussions within the core group, a revised version comprising 15 items is retained and modified from the original 20 items.
