Effects of a novel endoscopic reporting system with voice recognition on the endoscopic procedure time and report preparation time: propensity score matching analysis.

BACKGROUND: With the increase in endoscopic procedures, endoscopists are spending more time creating reports. Although medical reports have largely become electronic, most of the current reporting systems require manual operation. This study aimed to evaluate the efficacy of a novel endoscopic reporting system that uses voice recognition (VR) technology. METHODS: We retrospectively reviewed consecutive patients who underwent esophagogastroduodenoscopy between September 2019 and March 2020 at a general hospital in Japan. The novel reporting system, used during endoscopic procedures, is equipped with VR and provides automatic responses by playing back recognized words. Differences in total time spent on the endoscopic procedure and report preparation between the manual entry (ME) and VR groups were evaluated using a propensity score matching method. RESULTS: We enrolled 356 patients: 226 and 130 patients in the ME and VR groups, respectively. Propensity score matching created 101 matched pairs. After matching, the median report preparation time (311 vs. 383 s, P = 0.009) and median total time (765 vs. 842 s, P = 0.053) in the VR group were shorter than those in the ME group. The VR system independently shortened the total and report preparation times by 156 s (95% confidence interval, - 274 to - 37 s; P = 0.009) and 118 s (95% confidence interval, - 220 to - 15 s; P = 0.023), respectively, on multiple linear regression analysis. CONCLUSIONS: The VR system could save the report preparation time and the total time. This novel system may improve the efficiency of endoscopy-related tasks.

[Malignant gastrointestinal lymphoma with cicatricial stenosis after complete response to chemotherapy].

A 75-year-old woman presented complaining of anorexia. A malignant gastrointestinal lymphoma was diagnosed, and chemotherapy was initiated. After 2 months, she developed vomiting. Computed tomography (CT) revealed thickening of the jejunal wall and dilatation of the intestine proximal to that area. Positron emission tomography-CT showed no uptake. Small bowel stenosis due to cicatricial stenosis after chemotherapy was suspected. Laparoscopic partial resection of the stenotic small bowel segment was performed. Histopathologically, only granulation tissue was seen with no evidence of tumor. Occasionally, cicatricial stenosis can develop after chemotherapy for malignant gastrointestinal lymphoma. Therefore, this condition must be considered an important complication of treatment for this disease.

Laparoscopic omentectomy in primary torsion of the greater omentum: report of a case.

BACKGROUND: Torsion of the greater omentum is a rare cause of acute abdominal pain in adults and children. It is very difficult to make a correct diagnosis of torsion clinically because it mimics other acute pathologies; however, the preoperative diagnosis can be easily confirmed with the use of computed tomography (CT). Herein, we report a case of laparoscopic omentectomy for primary torsion of the omentum, which was not improved by conservative treatment. CASE PRESENTATION: A 50-year-old Japanese man presented to our hospital with acute right lower quadrant abdominal pain of a few hours' duration. Routine blood tests showed a white blood cell count of 8900/mm3, and the C-reactive protein (CRP) level was 8.13 mg/dl. Contrast-enhanced CT scan of the abdomen revealed twisting of the omentum with a local mass of fat density and fluid distributed in a whirling oval-shaped mass pattern at the right flank and iliac fossa. Therefore, the patient was admitted to our hospital based on a diagnosis of omental torsion. The patient was treated with conservative treatment with analgesics, anti-inflammatories, and antibiotics. Although his symptoms were ameliorated, his laboratory and radiological findings worsened. We performed laparoscopic omentectomy 6 days after admission. The resected omentum was 24 cm × 22 cm in size and was twisted and dark red in color, suggesting infarction. Histological analysis revealed that the specimen was ischemic and hemorrhagic omentum, accompanied by inflammatory infiltration. The patient's postoperative course was uneventful, and he was discharged 9 days later. CONCLUSION: This is a rare case of primary torsion of the greater omentum that was treated successfully with laparoscopic omentectomy. Considering the increase in surgical difficulty due to inflammation from prolonged torsion and the limited efficacy of conservative treatment, we conclude that surgical intervention is warranted as early as possible when torsion of the greater omentum is suspected.
