The published clinical research in 2018 in surgical infection are changing current opinions in the management of acute appendicitis, antibiotics usage, resuscitation of septic shock, and choice of nutritional therapy in critically ill patients. In the management of uncomplicated acute appendicitis, antibiotic therapy can be successful in selected patients who wish to avoid surgery. Delayed primary wound closure can not reduce superficial surgical site infection rates compared to primary wound closure for complicated appendicitis. Infusion of antibiotics 30 minutes before the start of operation may influence their prophylactic effect on surgical site infection. After adequate source control, long-course antibiotic therapy in critically ill post-operative patients is not associated with any clinical benefit. Although susceptible in the test, piperacillin-tazobactam can not replace carbapenems in patients with Escherichia coli and Klebsiella pneumoniae bloodstream infection that produce extended-spectrum beta-lactamase for definitive treatment. Deresuscitation of critically ill patients is associated with reduced mortality. Hydrocortisone therapy has potential role in the patients with septic shock and worth further evidence. The use of an energy-dense formulation for enteral delivery of nutrition can not improve 90-day survival rate in patients undergoing mechanical ventilation. Compared with early isocaloric parenteral nutrition, early enteral nutrition did not reduce mortality or the risk of secondary infections, but was associated with a greater risk of digestive complications in critically ill adults with septic shock.

PURPOSE: Surgeons may be uncertain about the optimal timing of appendectomy to decrease complications, especially for complicated appendicitis. The aim of the study was to compare clinical outcomes between early and late surgery for complicated appendicitis. METHODS: A prospectively maintained database of complicated appendicitis was queried. Elective interval surgery (EIS) group and early surgery (ES) were matched with propensity score and marked with a prefix ‘p.’ Patient characteristics and surgical outcomes were compared. RESULTS: The propensity score-matched EIS group had a lower chance to underwent ileo-cecectomy or right hemicolectomy (1.5% vs. 6.9%, P = 0.031), a tendency of lower rate of postoperative complication (6.9% vs. 13.7%, P = 0.067), a lower rate of wound infection (1.5% vs. 8.4%, P = 0.010), and shorter postoperative hospital stay (3.72 days vs. 5.82 days, P < 0.001) than the propensity score-matched ES group. Multivariate analysis showed that delayed surgery for more than 48 hours or urgent surgery due to failure of EIS and open conversion were independent risk factors for postoperative complications (P = 0.001 and P = 0.025, respectively). In subgroup analysis, high American Society of Anesthesiologists physical status classification and distant abscess or generalized ascites in initial CT increased the risk of failure of EIS. CONCLUSION: EIS can be a useful option for selected adult patients with complicated appendicitis.

PURPOSE: With varied reports on the impact of time to appendectomy on clinical outcomes, the purpose of this study was to determine the effect of preoperative in-hospital delay on the outcome for patients with acute appendicitis. METHODS: A retrospective review of 1,076 patients who had undergone an appendectomy between January 2010 and December 2013 was conducted. RESULTS: The outcomes of surgery and the pathologic findings were analyzed according to elapsed time. The overall elapsed time from onset of symptoms to surgery was positively associated with advanced pathology, increased number of complications, and prolonged hospital stay. In-hospital elapsed time was not associated with any advanced pathology (P = 0.52), increased number of postoperative complications (P = 0.14), or prolonged hospital stay (P = 0.24). However, the complication rate was increased when the in-hospital elapsed time exceeded 18 hours. CONCLUSION: Advanced pathology and postoperative complication rate were associated with overall elapsed time from symptom onset to surgery rather than in-hospital elapse time. Therefore, a short-term delay of an appendectomy should be acceptable.

OBJECTIVETo evaluate the feasibility and efficacy of Zhu's trocar placement (ZTP) in laparoscopic appendectomy (LA) in the treatment of complicated appendicitis.

METHODSClinical data of 139 complicated appendicitis patients undergoing LA at the First Affiliated Hospital of Wenzhou Medical University from June 2013 to December 2017 were retrospectively analyzed. ZTP-LA group comprised 59 cases and its procedure was as follows: 10 mm umbilical trocar was used as lens port; 12 mm trocar at crossing point of umbilical hole horizontal line and right midclavicular line was used as main operating port; 5 mm trocar at the crossing point of horizontal line 0-3 cm below umbilicus and right anterior axillary line was used as assist operating port with the drainage function for Douglas fossa and right iliac fossa; The operator and the assistant stood on the right side and the left side of the patient respectively. Traditional three-port group comprised 80 cases (8 cases converted to laparotomy, 72 cases enrolled finally) and its procedure was as follows: 10 mm lens port below umbilicus; 10-12 mm main operating port at lateral border of left lower rectus abdominis; 5 mm assist operating port above pubis; The operator and the assistant stood on left side of the patient. The operative time, time to oral semi-fluid, postoperative hospital stay, cost during hospitalization, and postoperative morbidity of complication were compared between two groups.

RESULTSBaseline data such as gender, age, WBC count, percentage of leukocyte, pathological finding and type were not significantly different between two groups(all P>0.05). The conversion rate in ZTP-LA was significantly lower than that in traditional three-port group [0%(0/59) vs. 10.0%(8/80),χ²=4.552,P=0.033]. Compared with traditional three-port group, ZTP-LA group showed shorter operative time [(47.8±20.1) minutes vs. (66.0±27.3) minutes, t=4.383,P<0.001], shorter time to oral semi-fluid [(35.0±20.7) hours vs. (59.3±32.8) hours, t=5.158,P<0.001], shorter postoperative hospital stay [(4.1±1.6) days vs. (5.5±2.2) days, t=4.162, P<0.001], lower postoperative morbidity of complication [3.4% (2/59) vs. 18.1%(13/72), χ²=6.879, P=0.009], lower incidence of postoperative intra-abdominal abscess [0%(0/59) vs. 11.1%(8/72), χ²=5.179, P=0.023], lower incidence of paralytic ileus [1.7%(1/59) vs. 12.5%(9/72), χ²=3.946, P=0.047] and less cost during hospitalization[(13 585±2909) yuan vs.(16 861±5334) yuan, t=4.463, P<0.001].

CONCLUSIONZTP-LA is safe, feasible and effective with advantages of faster recovery and less cost in the treatment of complicated appendicitis.

PURPOSE: Periappendiceal abscess (PAA) is a severe complicated appendicitis with high morbidity. Non-surgical treatment followed by interval appendectomy (IA) is associated with lower complication rate compared with emergency surgery (ES) and minimally invasive surgery (MIS) can be done more often. The purpose of this study is to assess the incidence and factors predictive of complications of surgery for PAA and to evaluate the clinical effectiveness of IA as a treatment policy to increase MIS. METHODS: Retrospectively, we reviewed 171 patients undergoing surgery for PAA between 2011 and 2016 at Ulsan University Hospital. The incidence and influence of different factors were assessed by univariate and multivariate analyses. RESULTS: In 171 patients, 28 (16.4%) developed postoperative complications, which included; wound complications (7.6%), intra-abdominal abscess (4.1%) and ileus (2.9%). In both analyses, only ES was independently associated with postoperative complications; (Relative risk, 15.0; 95% Confidence interval, 2.4~92.5). Comparing the IA and ES groups revealed that operative time, complication rate, laparoscopic approach, postoperative hospitalization, postoperative antibiotic use and bowel resection rate were significantly different. The postoperative complication rate of patients with PAA in ES group was 28.7%, which was statistically higher than that of IA group (3.6%). Especially, MIS rate was more than 9-times greater in the IA group (98.8% vs. 10.3%, p<0.001). Although the IA group required additional hospitalization, there was no statistical difference between the two groups in total length of hospital stay. CONCLUSION: Morbidity was high for patients who had emergency surgery for PAA. ES was the only factor associated with postoperative morbidity. IA can reduce the postoperative complication rate and allowed MIS to be used more often as a useful treatment policy for PAA.

BACKGROUND/AIMS: The past decades have seen increasing incidence and prevalence of inflammatory bowel disease (IBD) in China. This article aimed to summarize the current status and characteristics of surgical management for IBD in China. METHODS: We searched PubMed, Embase, and Chinese databases from January 1, 1990 to July 1, 2014 for all relevant studies on the surgical treatment IBD in China. Eligible studies with sufficient defined variables were further reviewed for primary and secondary outcome measures. RESULTS: A total of 74 studies comprising 2,007 subjects with Crohn's disease (CD) and 1,085 subjects with ulcerative colitis (UC) were included. The percentage of CD patients misdiagnosed before surgery, including misdiagnosis as appendicitis or UC, was 50.8%±30.9% (578/1,268). The overall postoperative complication rate was 22.3%±13.0% (267/1,501). For studies of UC, the overall postoperative complication rate was 22.2%±27.9% (176/725). In large research centers (n>50 surgical cases), the rates of emergency operations for CD (P=0.032) and in-hospital mortalities resulting from both CD and UC were much lower than those in smaller research centers (n≤50 surgical cases) (P=0.026 and P <0.001, respectively). Regarding the changes in CD and UC surgery over time, postoperative complications (P=0.045 for CD; P=0.020 for UC) and postoperative in-hospital mortality (P=0.0002 for CD; P=0.0160 for UC) both significantly improved after the year 2010. CONCLUSIONS: The surgical management of IBD in China has improved over time. However, the rates of misdiagnosis and postoperative complications over the past two decades have remained high. Large research centers were found to have relatively better capacity for surgical management than the smaller ones. Higher quality prospective studies are needed in China.

PURPOSE: Nonoperative management followed by an interval appendectomy is a commonly used approach for treating patients with perforated appendicitis with abscess formation. As minimally-invasive surgery has developed, single-port laparoscopic surgery (SPLS) is increasingly being used to treat many conditions. We report our initial experience with this procedure using a multichannel single-port. METHODS: The study included 25 adults who underwent a single-port laparoscopic interval appendectomy for perforated appendicitis with periappendiceal abscess by using a single-port with or without needlescopic grasper between June 2014 and January 2016. RESULTS: Of the 25 patients, 9 (36%) required percutaneous drainage for a median of 7 days (5-14 days) after insertion, and 3 (12%) required conversion to reduced-port laparoscopic surgery with a 5-mm port insertion because of severe adhesions to adjacent organs. Of 22 patients undergoing SPLS, 13 underwent pure SPLS (52.0%) whereas 9 patients underwent SPLS with a 2-mm needle instrument (36.0%). Median operation time was 70 minutes (30-155 minutes), and a drainage tube was placed in 9 patients (36.0%). Median total length of incision was 2.5 cm (2.0-3.0 cm), and median time to soft diet initiation and length of stay in the hospital were 2 days (0-5 days) and 3 days (1-7 days), respectively. Two patients (8.0%) developed postoperative complications: 1 wound site bleeding and 1 surgical site infection. CONCLUSION: Conservative management followed by a single-port laparoscopic interval appendectomy using a multichannel single-port appears feasible and safe for treating patients with acute perforated appendicitis with periappendiceal abscess.
