Excision of the urachal remnant using the abdominal wall-lift laparoscopy: A case report
Introduction: Here, we report the surgical excision of the urachal remnant using the abdominal wall-lift laparoscopy with a camera port in the umbilicus, combined with a small Pfannenstiel incision to optimally treat the bladder apex.
Presentation of case: A 21-year-old woman presented with periumbilical discharge and pain on urination. Contrast enhanced CT and MRI showed an abscess in the umbilical region that was connected to the bladder via a long tube-like structure. It was diagnosed as an infected urachal sinus. Partial excision of the umbilical fossa followed by dissection of the urachal remnant was easily performed using the abdominal wall-lift laparoscopy from the umbilicus down to the bladder without pneumoperitoneum or additional trocar placement. A Pfannenstiel incision was made above the pubis to get access to the junction between the urachal remnant and the bladder. Under direct vision, we succeeded in accurately dividing the remnant tract, and we adequately closed the bladder opening with absorbable sutures. This method has the advantage of easily closing peritoneal defects after excision of the urachal remnant with direct sutures under a laparoscopic view from the umbilicus. Cosmetic satisfaction was obtained postoperatively.
Discussion and conclusion: Urachal sinus excision using the abdominal wall-lift laparoscopy seems to surpass the previously reported methods in term of safety, cosmetics, and adequacy of surgical procedures
CLOSURE OF A REFRACTORY ENTEROCUTANEOUS FISTULA WITH PERCUTANEOUS INTESTINAL DRAINAGE-A CASE REPORT-
Retrocecal hernia successfully treated with laparoscopic surgery: A case report and literature review of 15 cases in Japan
Introduction: Retrocecal hernia is rare and involves strangulation ileus, and therefore, frequently requires emergency surgery following conservative therapy.
Presentation of case: We report an interesting case of a retrocecal hernia in a 65-year-old man, with a history of diabetes mellitus. The patient was admitted to our hospital with severe periumbilical pain and nausea. Abdominal computed tomography revealed an intestinal obstruction at a pericecal site, and dilatation of the small bowel at the oral side of the obstruction. The patient was initially treated with conservative therapy using long intestinal tube placement. On the 12th hospital day, the patient’s symptoms had not resolved, and laparoscopic surgery was performed. We diagnosed a retrocecal hernia based on laparoscopic findings and repaired it. The patient was discharged without complications on the 7th postoperative day.
Discussion and conclusion: Using laparoscopic exploration and suturing, we were able to perform a minimally invasive operation that may have promoted an earlier hospital discharge
A CASE REPORT OF INTRACTABLE ENTEROCUTANEOUS FISTULA AFTER ILEOCECOTOMY TREATED WITH ENDOSCOPIC INJECTION OF HISTOACRYL
Silk suture granuloma with false-positive findings on PET/CT accompanied by peritoneal metastasis after colon cancer surgery
Introduction: Suture granuloma is a rare benign tumor caused by suture material, which usually appears several months or years after surgery.
Presentation of case: A 71-year-old man underwent sigmoidectomy and partial hepatectomy (S6) for sigmoid colon cancer and synchronous liver metastasis at a previous hospital. At 4 postoperative months, surveillance computed tomography (CT) revealed a suspicious tumor at the hepatic resection stump. He was referred to our hospital for further examinations and treatments. Positron emission tomography/CT (PET/CT) revealed abnormal hepatic F-18 fluorodeoxyglucose (FDG) uptake below the diaphragm at the S5/S8 surface. Peritoneal metastasis was suspected and surgery was performed. White nodules were found in the Douglas pouch. A diagnosis of adenocarcinoma was confirmed by frozen section analysis of the nodules. He underwent a partial hepatectomy (S5/S8) and partial resection of the diaphragm. Pathological examination showed that the liver tumor was a foreign body granuloma that included silk suture material.
Discussion: Although postoperative PET/CT surveillance is useful following malignant tumor resection, it is important to note that PET/CT false-positive findings are possible. Furthermore, PET/CT cannot detect small peritoneal metastases, necessitating a thorough abdominal examination.
Conclusion: In cases of malignancy, the possibility of postoperative suture granuloma should be considered. In addition, a thorough surgical examination of the abdomen should be performed in cases of suspected recurrence

Change over Time in the Risk of Death among Japanese COVID-19 Cases Caused by the Omicron Variant Depending on Prevalence of Sublineages
To assess temporal changes to the risk of death in COVID-19 cases caused by the Omicron variant, we calculated age-standardized case fatality rates (CFR) in patients aged ≥40 years over nine diagnostic periods (3 January to 28 August 2022) in ten Japanese prefectures (14.8 million residents). Among 552,581 study subjects, we found that there were 1836 fatalities during the isolation period (up to 28 days from date of onset). The highest age-standardized CFR (0.85%, 95% confidence interval (CI):0.78–0.92) was observed in cases diagnosed in the second 4-week period (January 31 to February 27), after which it declined significantly up to the 6th 4-week period (0.23%, 95% CI: 0.13–0.33, May 23 to June 19). The CFR then increased again but remained at 0.39% in the eighth period (July 18 to August 28). The CFR in cases with the BA.2 or BA.5 sublineages in the age range 60–80 years was significantly lower than that with BA.1 infections (60 years: 0.19%, 0.02%, 0.053%, respectively; 70 years: 0.91%, 0.33%, 0.39%; ≥80 years: 3.78%, 1.96%, 1.81%, respectively). We conclude that the risk of death in Japanese COVID-19 patients infected with Omicron variants declined through February to mid-June 2022
