Purpose: We conducted this study to compare the perioperative outcomes of laparoscopic surgery (LS) vs. open surgery (OS) for repairing colonoscopic perforation, and to evaluate the possible predictors of complications. Method: We reviewed the medical records of patients who underwent surgical repair of colonoscopic perforation by LS or OS between January 2005 and June 2019 at six Hallym University-affiliated hospitals. Multivariable analysis was performed to identify the predictors of postoperative complications. Results: Of the total 99 patients, 40 underwent OS and 59 underwent LS. The postoperative hospital stay and the time to resuming a soft diet were shorter in the LS group than in the OS group (P = 0.017 and 0.026, respectively). The complication rate and Clavien–Dindo classification were not significantly different between the two groups. Multivariable analysis revealed that an American Society of Anesthesiologists score (ASA) ≥ 3 and switching from non-operative management to surgical treatment were independently associated with complications (P = 0.025 and 0.010, respectively). Conclusion: LS may be a safe alternative to OS for repairing colonoscopic perforation with a shorter postoperative hospital stay and time to resuming a soft diet. Patients with an ASA score ≥ 3 and those with changes to their planned treatment should be monitored carefully to minimize their risk of complications. [ABSTRACT FROM AUTHOR]

Background: It is generally believed that appendectomy should be performed immediately to prevent perforation and complications. Therefore, our objectives were to investigate the effect of timing of appendectomy on the incidence of perforation and complications.Methods: We retrospectively reviewed the medical records of patients who underwent laparoscopic appendectomy between January 2014 and June 2015. The time from symptom onset to appendectomy was categorized into three periods: time from symptom onset to hospital admission (symptomatic time), time from admission to appendectomy (hospitalization time), and time from symptom onset to appendectomy [symptomatic period + hospitalization period (overall time)]. Multivariable analyses were performed to identify independent factors associated with perforation and complications.Results: A total of 1753 patients were included in the present study. Perforation occurred in 28.2% of patients, and postoperative complications occurred in 10.0% of patients. Multivariable analysis showed that BT > 38 °C (P = 0.006), WBC count >13,000 cells/µl (P = 0.02), neutrophil ratio >80% (P < 0.001), and symptomatic time >24 h (P < 0.001) were independent factors of appendiceal perforation, while the neutrophil ratio >80% (P < 0.001) and symptomatic time >48 h (P = 0.003) were independently associated with complications.Conclusions: The present study showed that the symptomatic time and overall time were significantly associated with perforation and complications, whereas hospitalization time was not associated with either perforation or complications.

Background Korea has a nationalized health system. The aim of this study was to evaluate the impact of the Korea diagnosis related group–based prospective payment system (K-DRG/PPS) on the use of medical resources and the rate of adverse events during laparoscopic appendectomy. Methods We included patients who underwent laparoscopic appendectomy at Dongtan Sacred Heart Hospital, Korea, between November 2012 and February 2014. The patients were divided into two groups: before-DRG/PPS or after-DRG/PPS groups. The length of the postoperative hospital stay (LOS) and medical costs were indicators of the medical resources. Medical costs included those of the initial hospital stay, outpatient clinic, readmission, and the sum of these charges. Complication and readmission rates were indicators of the rates of adverse events. Results After the implementation of the DRG/PPS, length of the hospital stay decreased by 10% (4.9 d before versus 4.4 d after DRG/PPS; P < 0.001). The initial hospital stay and total cost were significantly lower in the after-DRG/PPS group (both P < 0.001). The complication rates during the initial hospital stay (3.5% before versus 2.3% after DRG/PPS; P = 0.225) and the readmission rates (4.3% versus 2.5%, respectively; P = 0.227) were statistically similar. Conclusions This study shows that the K-DRG/PPS for laparoscopic appendectomy had no negative effect on the rate of adverse events and reduced the use of medical resources. Further evaluation of other procedures is required to determine the overall effects of the K-DRG/PPS. [ABSTRACT FROM AUTHOR]
