RESUMEN
BACKGROUND: This study aimed to examine the clinical characteristics of 11 patients undergoing laparoscopic adenomyomectomy guided by intraoperative ultrasound elastography and this technique's feasibility. PATIENTS AND METHODS: Eleven patients undergoing laparoscopic adenomyomectomy using ultrasound elastography for adenomyosis at Kawasaki Medical School Hospital in Okayama, Japan between March 2020 and February 2021 were enrolled. Operative outcomes included operative time, operative bleeding, resected weight, operation complications, percent change in hemoglobin (Hb) values, and uterine volume pre- and postoperatively. Dysmenorrhea improvement was evaluated by changes in visual analog scale (VAS) scores pre- and 6- and 12-months postoperatively. RESULTS: The median operative time and bleeding volume was 125 min (range, 88-188 min) and 150 mL (10-450 mL), respectively. The median resected weight was 5.0 g (1.5-180 g). No intraoperative or postoperative blood transfusions or perioperative complications were observed. The median changes in uterine volume, Hb value, and VAS score were -49% (-65 to -28%), -3% (-11 to 35%), and -80% (-100 to -50%), respectively. The median follow-up period post-surgery was 14 months (7-30 months). Adenomyosis recurrence was not observed in the patients during the follow-up period. CONCLUSIONS: Laparoscopic adenomyomectomy using ultrasound elastography guidance is minimally invasive and resects as many adenomyotic lesions as possible.
RESUMEN
Medullary carcinoma of the colorectum is a relatively new histological subtype that was first described in the eighth edition of the Japanese classification of colorectal, appendiceal, and anal carcinoma. In our institution, only 3 cases of medullary carcinoma have been diagnosed since 2013. Case #1 was a 93-year-old woman with type 1 ascending colon cancer; she received a right hemicolectomy. The tumor invaded the subserosal layer, but no lymph nodal metastasis was observed. Case #2 was a 91-year-old woman with obstructive ascending colon cancer. After intracolonic decompression using the transnasal ileus tube, she received a right hemicolectomy. This tumor also extended into the subserosal layer without lymph nodal metastasis. Case #3 was a 65-year-old woman with a family history of cancers; she received a right hemicolectomy for cecal cancer with an aberrant elevation of serum tumor markers such as CEA and CA19-9. The tumor invaded the subserosal layer with regional lymph nodal metastases. Notably, these 3 cases were females who had right-sided tumors and all showed diminished expressions of MLH1 and PMS2 mismatch repair-associated genes, together with epidemiological characteristics of medullary carcinoma. Herein, we report their pathological features along with the corresponding literature review.

A 44-year-old patient progressed from nonalcoholic fatty liver (NAFL) to nonalcoholic steatohepatitis (NASH) cirrhosis. She was diagnosed with NAFL via a liver biopsy. At 56 years old, she was diagnosed with NASH stage 3 via a second liver biopsy. One year later, she was diagnosed with NASH cirrhosis via a third liver biopsy. This is the first study to report the gradual deterioration of liver histology shown via three liver biopsies and fibrosis markers in a patient who progressed from NAFL to NASH cirrhosis. Following menopause, it is necessary to be aware of the rapid development of liver fibrosis.
