We use transumbilical laparoscopic-assisted appendectomy (TULAA) with a lifting retractor as the surgical technique of first choice for acute appendicitis. Although this technique provides excellent cosmetic results and contributes to reducing medical costs, it is less advantageous in difficult-to-complete cases that require conversion to pneumoperitoneum or additional ports. We retrospectively reviewed the records of 76 patients who underwent laparoscopic appendectomy between June 2020 and March 2023 (43 in a TULAA group and 33 in a pneumoperitoneal conversion group) to identify preoperative factors associated with pneumoperitoneal conversion. Univariate analysis showed significant differences for preoperative C-reactive protein (CRP) level, age, and body mass index. Logistic regression analysis identified preoperative CRP level and age as significant risk factors for pneumoperitoneal conversion. The pneumoperitoneal conversion rate was 12.5%, 48.2%, and 68% for patients with 0, 1, and 2 preoperative risk factors, respectively, indicating patients with 2 risk factors were more likely to undergo pneumoperitoneal conversion. These data may inform the selection of the surgical technique and the decision to convert to pneumoperitoneum.

Non-alcoholic fatty liver disease is currently the most common chronic liver disease, affecting up to 25% of the global population. Simple fatty liver, in which fat is deposited in the liver without fibrosis, has been regarded as a benign disease in the past, but it is now known to be prognostic. In the future, more emphasis should be placed on the quantification of liver fat. Traditionally, fatty liver has been assessed by histological evaluation, which requires an invasive examination; however, technological innovations have made it possible to evaluate fatty liver by non-invasive imaging methods, such as ultrasonography, computed tomography, and magnetic resonance imaging. In addition, quantitative as well as qualitative measurements for the detection of fatty liver have become available. In this review, we summarize the currently used qualitative evaluations of fatty liver and discuss quantitative evaluations that are expected to further develop in the future.

Nonalcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease, and there has been a rapid increase in cases worldwide. NAFLD is rapidly becoming the leading cause of hepatocellular carcinoma and is also associated with an increased risk of cardiovascular disease or exacerbation of other organ diseases, thus posing a significant health problem from both a medical and a socioeconomic perspective. NAFLD is a systemic disease and requires the involvement of numerous medical professionals. Multidisciplinary collaboration, in which different professionals within different specialties come together and work together toward a common goal, supports better patient care by integrating perspectives of multiple experts and facilitating the exchange of opinions. Due to the large number of potential patients, gastroenterologists and hepatologists cannot manage the patients alone, and collaboration between specialists in various fields, including family doctors, dentists, nutritionists, and pharmacists is required for treatment of NAFLD. This review will discuss NAFLD from the perspective of various specialties and introduce multidisciplinary collaboration.

Elevated fibroblast growth factor 23 (FGF23) in X-linked hypophosphatemia (XLH) results in rickets and phosphate wasting, manifesting by severe bone and dental abnormalities. Burosumab, a FGF23-neutralizing antibody, an alternative to conventional treatment (phosphorus and active vitamin D analogs), showed significant improvement in the long bone phenotype. Here, we examined whether FGF23 antibody (FGF23-mAb) also improved the dentoalveolar features associated with XLH. Four-week-old male Hyp mice were injected weekly with 4 or 16 mg·kg-1 of FGF23-mAb for 2 months and compared to wild-type (WT) and vehicle (PBS) treated Hyp mice (n = 3-7 mice). Micro-CT analyses showed that both doses of FGF23-mAb restored dentin/cementum volume and corrected the enlarged pulp volume in Hyp mice, the higher concentration resulting in a rescue similar to WT levels. FGF23-mAb treatment also improved alveolar bone volume fraction and mineral density compared to vehicle-treated ones. Histology revealed improved mineralization of the dentoalveolar tissues, with a decreased amount of osteoid, predentin and cementoid. Better periodontal ligament attachment was also observed, evidenced by restoration of the acellular cementum. These preclinical data were consistent with the retrospective analysis of two patients with XLH showing that burosumab treatment improved oral features. Taken together, our data show that the dentoalveolar tissues are greatly improved by FGF23-mAb treatment, heralding its benefit in clinics for dental abnormalities.

Background/Aims:
Natural history of chronic intestinal pseudo-obstruction (CIPO), a rare disease characterized by episodes of non-mechanical obstruction, is unclear in adults. This study evaluates the clinical course of CIPO and palliative care needs of patients.
Methods:
From October 2010 to September 2021, 74 patients who underwent cine MRI and had a definitive diagnosis of CIPO were prospectively included. We investigated disease etiology and outcomes, age at onset, nutritional status at consultation (body mass index and serum albumin), hydrogen breath test results, and total parenteral nutrition (TPN) during the disease course.
Results:
Forty-seven patients (64%) were women, with a mean age of 44 years at onset and 49 years at diagnosis. Primary CIPO was observed in 48 patients (65%). Secondary CIPO was observed in 26 cases (35%), of whom 18 (69%) had scleroderma. The mean body mass index, serum albumin level, and hydrogen breath test positivity rate were 17 kg/m2 , 3.8 mg/dL, and 60%, respectively. TPN and invasive decompression therapy were required by 23 (31%) and 18 (24%) patients, respectively. Intestinal sterilization was performed in 51 (69%) patients and was effective in 33 (65%); of these, 28 (85%) were taking metronidazole. Seven (9%) patients used opioids. There were 9 deaths (12%), including 5 (56%) from infection and 2 (22%) from suicide. Of the deaths, 6 (67%) and 4 (44%) underwent TPN management and decompression therapy, respectively. Fifty-one patients (69%) wanted palliative care.
Conclusion
CIPO is a rare, severe, and under-recognized disease. Standardization of treatment strategies, including palliative care and psychiatric interventions, is desired.

Objective: Most cases of severe metabolic alkalosis have many causes that may result in renal failure and death. Therefore, these should be treated promptly for successful recovery.Patient: A 61-year-old man was hospitalized due to an acute kidney injury (creatinine level of 4.36 mg/dL) after a 3-month history of anorexia and recurrent vomiting. He had been treated for tuberculosis in the past.Results: Blood gas analysis revealed severe metabolic alkalosis with pH=7.66, HCO3=94 mmol/L, and pCO2=82.0 mmHg. Routine biochemical examination revealed severe hypokalemia (K 2.9 mEq/L) that was associated with prolonged QTc interval (0.52 seconds) on the electrocardiogram. Gastrofiberscopic examination also revealed severe stenosis and ulcerated scarring of the gastric pylorus and severe esophagitis. Intravenous hydration and correction of hypokalemia improved renal function and resolved metabolic alkalosis. An investigation that was repeated after 6 days revealed a creatinine level of 1.58 mg/dL, pH=7.47, HCO3=23.4 mmol/L, K=3.6 mEq/L, and QTc of 0.45 seconds. The patient underwent gastrectomy and adenocarcinoma was observed.Conclusion: We described a resolved case of severe metabolic alkalosis and acute kidney injury in a rural medical setting following conservative management.
