INTRODUCTIONThe aim of this study was to investigate the clinical efficacy and safety of laparoscopic appendectomy (LA) during pregnancy by comparing the operative and obstetric outcomes of patients who during pregnancy underwent LA performed by an expert gynaecologic laparoscopist (LA group) with those patients who underwent an open appendectomy (OA) by a general surgeon (OA group).

MATERIALS AND METHODSIn this retrospective study, we evaluated all patients consecutively who had undergone appendectomy for acute appendicitis during pregnancy from January 2000 to December 2010. Twenty-eight patients underwent OA and 15 were treated by LA. We reviewed the clinical charts and analysed the data for each patient's age, parity, body mass index, gestational age at appendectomy, type of appendectomy, operating time, haemoglobin change, hospital stay, histopathological results, postoperative analgesics, complications, and obstetric outcomes.

RESULTSThere were no significant differences between the OA and LA groups in terms of clinical characteristics, hospital stay, haemoglobin change, return of bowel activity, complication rates, gestational age at delivery, and birth weight. However, there were significantly shorter operating time and less usage of postoperative analgesics in LA group.

CONCLUSIONLA performed by an expert gynaecologist can be a safe and effective method for treating acute appendicitis during the first and second trimester of pregnancy.

PURPOSE: Acute appendicitis has been reported to be relatively rare in pediatric leukemia patients but there is no official data for this in Korea. And there is no consensus for its treatment in this population. MATERIALS AND METHODS: We conducted a retrospective study of 7 patients diagnosed with appendicitis among 1209 pediatric patients who were diagnosed with leukemia from 1996 to 2008 at a single institution in Korea. RESULTS: The median age at the time of the diagnosis of appendicitis was 12 years (range: 3-15 years), and 3 of the patients were male. The median absolute neutrophil count (ANC) at the time of diagnosis was 0.99x10(9)/L (range: 0-3x10(9)/L). The mean time from the onset of symptoms to the diagnosis was 4 days. All 7 leukemia patients with appendicitis underwent surgery and they demonstrated a survival of 100% without significant complications. CONCLUSION: The incidence of appendicitis in pediatric leukemia patients was 0.57% in our study. Early diagnosis with abdominal ultrasound or computed tomography and early surgical resection in leukemic patient with acute appendicitis may be a safer and more effective treatment option. Even when perforation has already occurred and when the patient has an ANC of 0x10(9)/L, surgical treatment may improve overall survival without incurring significant complications.

OBJECTIVETo compare the advantages and disadvantages of laparoscopic versus open appendectomy in patients with chronic appendicitis.

METHODSTwo hundred twenty- four patients were divided into laparoscopic group (n=98) and open appendectomy group (n=126) according to individual willing. Prospective non- randomized study was performed to compare the operative time, operative bleeding, hospitalization time, the discovery and management concerned in operation. Abdominal pain in these chronic appendicitis cases was followed up.

RESULTSThe operative time was (54.8+/-21.8) min in open group and (51.8+/-18.0) min in laparoscopic group (t=0.80,P > 0.05). The operative bleeding was (18.6+/-23.3) ml in open group and (9.8+/-4.7) ml in laparoscopic group (t=3.13, P < 0.05). The hospitalization time was (8.9+/-5.3) d in open group and (6.8+/-3.0) d in laparoscopic group (t=2.66,P < 0.05). Twenty- five cases had abdominal adhesion in laparoscopic group, including 9 cases of adhesion around appendix, 6 cases of adhesion between ileocecum and anterior or lateral abdominal wall, 4 cases of adhesion between epiploon and abdominal wall or intestines, 6 cases of adhesion around colon and others. All adhesion had been dissected. Fourteen cases adhesion around appendix had been discovered in 126 cases of open group and dissected (chi(2) =7.95,P < 0.05). In follow- up research, 24 cases still had chronic abdominal pain in 98 case of open group, and 9 cases had chronic abdominal pain in 87 of laparoscopic group, the difference was significant (chi(2)=6.29,P < 0.05).

CONCLUSIONThe laparoscopic appendectomy possesses more advantages in treating chronic appendicitis and can decrease the incidence of chronic abdominal pain after operation.

INTRODUCTIONThe aim of this study was to analyse the feasibility, safety and benefits of laparoscopic appendicectomy (LA) in comparison with open appendicectomy (OA) for perforated appendicitis (PA) in children.

MATERIALS AND METHODSA retrospective analysis of all consecutive cases of PA who underwent OA or LA between July 2001 and April 2004 was done. The patient demographics, duration of symptoms and operative findings were noted and the feasibility, safety and benefits of LA were analysed with respect to postoperative recovery and complications.

RESULTSOne hundred and thirty-seven consecutive patients with PA underwent either OA (n = 46) or LA (n = 91). Both groups were comparable with respect to patient demographics, duration of symptoms and operative findings. The mean operative time was 106.5 min (95% CI, 100.2 - 112.8) in the LA group and 92.8 min (95% CI, 82.9-102.7) in the OA group (P = 0.02). The return to afebrile status after surgery was significantly faster in the LA group [mean, 45.4 hours (95% CI, 36.8-54)] than the OA group [mean, 77 hours (95% CI 56.7-97.3)] (P = 0.007). The mean duration for postoperative opioid analgesia was 2.5 days (95% CI, 2.2-2.7) for LA and 3.2 days (95% CI, 2.9- 3.6) for OA (P = 0.001). The resumption of oral feeds after surgery was at 3.1 days (95% CI, 2.8-3.3) for LA and 3.7 days (3.4-4.1) for OA (P = 0.005). The length of the hospital stay was shorter in the LA group [mean, 6.5 days (95% CI, 6.1-6.8)] as compared to that of the OA group [mean, 8.2 days (95% CI, 7.1-9.3)] (P = 0.006). Postoperative complications included wound infection, adhesive intestinal obstruction and pelvic abscess formation. The incidence of these complications was 5.6% in the LA group and 19.6% in the OA group (P = 0.01). Nine patients (9.8%) needed conversion to open surgery in the LA group. None of the LA patients had wound infection.

CONCLUSIONLA is feasible, safe and beneficial in children with PA.

PURPOSE: Analyses of risk factors associated with surgical site infections (SSIs) after laparoscopic appendectomy (LA) have been limited. Especially, the association of an underweight body mass index (BMI) with SSIs has not been clearly defined. This study aimed to identify the impact of underweight BMI in predicting SSIs after LA. MATERIALS AND METHODS: The records of a total of 101 consecutive patients aged > or =16 years who underwent LA by a single surgeon between March 2011 and December 2012 were retrieved from a prospectively collected database. The rate of SSIs was compared among the underweight, normal and overweight and obese groups. Also, univariate and multivariate analyses were performed to identify the factors associated with SSIs. RESULTS: The overall rate of SSIs was 12.8%. The superficial incisional SSI rate was highest in the underweight group (44.4% in the underweight group, 11.0% in the normal group, and 0% in the overweight and obese group, p=0.006). In univariate analysis, open conversion and being underweight were determined to be risk factors for SSIs. Underweight BMI was also found to be a significant predictor for SSIs in multivariate analysis (odds ratio, 10.0; 95% confidence interval, 2.0-49.5; p=0.005). CONCLUSION: This study demonstrated underweight BMI as being associated with SSIs after LA. Surgeons should be more cautious to prevent SSIs in patients that are underweight when performing LA.
