ABSTRACT
BACKGROUND: Gallbladder rupture is common in laparoscopic cholecystectomy because the gallbladder is usually in acute or chronic inflammation status. The gallstones may sometime be spilled into the peritoneal cavity, resulting in intra-abdominal abscess if the gallstones were not retrieved. The diagnosis of intra-abdominal abscess caused by unretrieved gallstone can usually be correctly identified in the routine imaging studies, such as abdominal ultrasonography or computed tomography (CT). Here we present a case of abscess formation from unretrieved gallstone following laparoscopic cholecystectomy, which mimics the imaging findings of metastatic gallbladder adenocarcinoma. CASE SUMMARY: This case described a 78-year-old man who received laparoscopic cholecystectomy and gallbladder adenocarcinoma was diagnosed after surgery. After adjuvant chemotherapy, the following up abdominal CT showed several small nodules at right upper abdomen and peritoneal carcinomatosis is considered. Repeated laparoscopic surgery for the excision of seeding tumor was conducted and the pathological diagnosis of the nodules and mass was inflammatory tissues and gallbladder stone. CONCLUSION: Spilled gallstones are a common complication during laparoscopic cholecystectomy and some gallstones fail to be retrieved due to the size or the restricted view of laparoscopic surgery. For spilled gall bladder stones, surgeons may consider regular computerized tomography follow-up, and if necessary, laparoscopic examination can be used as a means of confirming the diagnostic and treatment.
ABSTRACT
BACKGROUND: This study investigated whether the time from emergency room registration to appendectomy (ETA) would affect the incidence of perforation and postoperative complications in patients with acute appendicitis. METHODS: Patients who underwent an appendectomy at the Ren-Ai branch of Taipei City Hospital between January 2010 and October 2012 were retrospectively reviewed. Their demographics, white blood cell count, C-reactive protein, body temperature, computed tomography scan usage, operation method, pathology report, postoperative complication, length of hospital stay, and ETA were abstracted. Multivariate analysis was performed to search the predictors, including ETA, of outcomes for the perforation and postoperative complication rates. RESULTS: A total of 236 patients were included in the study. Perforation occurred in 12.7% (30/236) and postoperative complications developed in 24.1% (57/236) of these patients. There were 121 patients with ETA <8 hours, 88 patients with ETA of 8-24 hours, and 27 patients with ETA >24 hours; patients with ETA >24 hours had significantly longer hospital stay. Univariate analysis showed that perforated patients were significantly older, and had higher C-reactive protein level, longer hospital stay, and higher complication rate. Patients who developed postoperative complications were significantly older, and had higher neutrophil count, less use of computed tomography, and higher open appendectomy rate. After multivariate analysis, age ≥55 years was the only predictor for perforation [odds ratio (OR) = 3.65; 95% confidence interval (CI), 1.54-8.68]; for postoperative complications, age ≥55 years (OR = 1.65; 95% CI, 1.84-3.25), perforated appendicitis (OR = 3.17; 95% CI, 1.28-7.85), and open appendectomy (OR = 3.21; 95% CI, 1.36-7.58) were associated. ETA was not a significant predictor in both analyses. CONCLUSION: In our study, it was observed that although longer ETA was associated with longer hospitalization, ETA was not correlated with postoperative complications. Our results inclined toward the position that appendectomy can be performed as a semielective surgery.
