This multicenter, prospective, observational cohort study assessed opioid induced constipation (OIC) in Japanese patients with cancer. Eligible patients had stable cancer and an ECOG PS of 0‐2. OIC incidence based on the Rome IV diagnostic criteria was determined by patient diary entries during the first 14 days of opioid therapy. The proportion of patients with OIC was calculated for each 1‐week period and the overall 2‐week study period. Secondary measurements of OIC included the Bowel Function Index (BFI) score (patient assessment administered by physician), spontaneous bowel movements (SBMs) per week (patient assessment), and physician assessments. Medication for constipation was allowed. Two hundred and twenty patients were enrolled. The mean morphine‐equivalent dose was 22 mg/day. By Rome IV criteria, the cumulative incidence of OIC was 56% (95% CI: 49.2%‐62.9%); week 1, 48% (95% CI: 40.8%‐54.6%); week 2, 37% (95% CI: 30.1%‐43.9%). The cumulative incidence of OIC was lower in patients who received prophylactic agents for constipation (48% [95% CI: 38.1%‐57.5%]) than in patients who did not (65% [95% CI: 55.0%‐74.2%]). The cumulative incidences of OIC were 59% (95% CI: 51.9%‐66.0%), 61% (95% CI: 54.3%‐68.1%), and 45% (95% CI: 38.0%‐51.8%) based on BFI scores, physician assessments, and SBM frequency, respectively. Frequency of BMs/week before starting opioids was the most influential factor for the occurrence of OIC. Utilization of prophylactic agents for constipation was associated with a modest effect on reducing the incidence of OIC. The incidences of OIC reported were variable depending on the diagnostic tool involved.
Background Formation of a liver abscess due to gastrointestinal perforation by a foreign body is rare. In addition, there are few case reports on laparoscopic surgical treatment of a liver abscess caused by perforation of the gastrointestinal tract by a foreign body. Case presentation A 51-year-old man visited our hospital because of fever and anorexia. There were no physical findings except for fever. He had no comorbidities or surgical history. Laboratory tests showed increased inflammatory marker and liver enzyme levels. Abdominal ultrasonography showed a hypoechoic lesion in the left lobe of the liver. Abdominal contrast-enhanced computed tomography revealed an air-containing abscess in the left side of the liver and a high-density linear object. We diagnosed a liver abscess secondary to stomach perforation by a foreign body. Emergency laparoscopic surgery identified a fish bone in the abscess that formed between the stomach and liver. We succeeded in removing the fish bone laparoscopically. The patient was discharged without any postoperative complications on day 11. Conclusions A liver abscess secondary to perforation of the gastrointestinal tract by a foreign body usually requires surgical treatment. Foreign body removal is important to prevent recurrence of liver abscess. In cases with the foreign body located at the liver margin, a laparoscopic approach to the abscess is very useful.
HighlightsAccurate preoperative diagnosis of gallbladder torsion is challenging because of the absence of clinical characteristics associated with it.Careful attention to symptoms during clinical presentation, including acute severe pain in the right quadrant and gallbladder deviation observed during radiological investigation, is required for accurate diagnosis of the condition.Upon confirmation of diagnosis, laparoscopic cholecystectomy would be the gold-standard treatment option rather than open cholecystectomy.
