Increased difficulty and complications of delayed laparoscopic cholecystectomy following percutaneous transhepatic gallbladder drainage in acute cholecystitis: a retrospective study.

BACKGROUND: Percutaneous transhepatic gallbladder drainage (PTGBD) is a relatively less invasive alternative treatment to cholecystostomy. However, the influence of the difficulty of delayed laparoscopic cholecystectomy (DLC) after PTGBD on clinical outcomes remains unknown. This study aimed to evaluate the clinical effects of DLC following PTGBD. METHODS: The clinical data of 113 patients diagnosed with moderate (grade II) acute cholecystitis according to the 2018 Tokyo Guidelines in the acute phase and who underwent DLC in our hospital from January 2018 to February 2022 were retrospectively collected and separated into two groups according to whether they received PTGBD treatment in the acute stage. The PTGBD group comprised 27 cases, and the no-PTGBD group included 86 cases. The TG18 difficulty score was used to evaluate every surgical procedure in the cases by reviewing the surgical videos. The clinical baseline characteristics and post-treatment outcomes were also evaluated. RESULTS: Both groups showed significant differences in length of postoperative stay, blood loss, operation time, and difficulty score. The PTGBD group showed a significantly longer postoperative stay and operation time, more blood loss, and a much higher difficulty score than the no-PTGBD group. Conversion rates did not differ. The morbidity rate in the PTGBD group was statistically higher. CONCLUSIONS: PTGBD is an efficient way to relieve the symptoms of acute cholecystitis. However, it may increase the difficulty and complications of DLC.

Can the parkland grading scale predict the difficulty of laparoscopic cholecystectomy? A new approach to validation.

BACKGROUND: The Parkland Grading Scale (PGS) is an intraoperative grading scale to stratify gallbladder disease severity during laparoscopic cholecystectomy (LC). We evaluated the usefulness of the PGS in predicting the difficulty levels of LC procedures using a novel approach. METHODS: A total of 261 patients diagnosed with cholelithiasis and cholecystitis who underwent LC were assessed. The PGS and the surgical difficulty grading system were used to evaluate surgical procedures by reviewing the operation videos. Clinical baseline characteristics and post-treatment outcomes were also recorded. Differences between the five PGS grades in terms of surgical difficulty scores were analyzed using the Jonckheere-Terpstra test. The relationship between PGS grades and surgical difficulty scores was assessed using Spearman's Rank correlation. Finally, the linear trends between morbidity scores and PGS grades were evaluated using the Mantel-Haenszel test. RESULTS: There was a significant difference in the surgical difficulty scores for the five PGS grades (p < 0.001). In pairwise comparison, each grade (1-5) was significantly different from the others (p < 0.05) in terms of surgical difficulty, except Grade 2 vs. 3 (p = 0.07) and Grade 3 vs. 4 (p = 0.08). There was a significant correlation between PGS grades and surgical difficulty scores (rs = 0.681, p < 0.001). There was also a significant linear association between morbidity and PGS grades (p < 0.001). Spearman's R value was 0.176 (p = 0.004). CONCLUSION: The PGS can accurately assess the surgical difficulty level of LC. The precision and conciseness of the PGS make it suitable for use in future research.

The clinical significance of body mass index in the early evaluation of acute biliary pancreatitis.

Objective: Obesity has increased across the globe in recent years and is considered an established risk factor for many diseases. The main objective was to investigate the early assessment value of Body Mass Index (BMI) in the prediction of severity in acute biliary pancreatitis (ABP) and by using BMI to evaluate the severity of ABP. Methods: The retrospective analysis was designed to assess the relationship between Body Mass Index and the severity of acute pancreatitis in Beijing Jishuitan Hospital from January 2019 to December 2021. The SPSS 24.0 software was used for statistical analysis, Logistic Regression, and ROC curve for the factors affecting the severity of acute biliary pancreatitis. Results: A total of 259 ABP patients were analyzed in our study. The BMI was significantly correlated with the Ranson scoring and MCTSI scoring (p = 0.000, 0.000). The difference in BMI in different severity of ABP patients was statistically significant (p = 0.000). The Logistic Regression analyses confirmed that BMI was an independent risk factor for the severity of ABP (p = 0.035). Combined detection of BMI, WBC, serum calcium, and SAMY in prognosis of the severity of acute pancreatitis positive rate is higher than single positive rate. Conclusion: The BMI gradually increased with the severity of acute pancreatitis and was an independent risk factor for the condition. Combined detection of BMI and medical tests can effectively improve acute pancreatitis patients' clinical diagnostic accuracy and early treatment, and help to reduce complications.

Complete colonic duplication presenting as hip fistula in an adult with pelvic malformation: A case report.

BACKGROUND: Alimentary tract duplication (ATD) is a rare congenital anomaly. Thus, a case of ATD with a complete colonic duplication isolated in the abdominal cavity with a fistula and multiple malformations is very distinctive. These characteristics show the variability of this disease and explain why it tends to be challenging to diagnose and treat. CASE SUMMARY: A 25-year-old woman with a history of a fistula opening in her right hip since birth presented with the irregular discharge of foul fluid from the fistula and intermittent abdominal pain. Contrast-enhanced computed tomography and magnetic resonance imaging findings revealed a duplicated tube isolated in her abdominal pelvic cavity along with a pelvic malformation and double ureter. Right foot radiographic examination showed pes cavus. During surgery, the tube appeared to be an almost complete colonic structure and was verified to be connected to the fistula. All of the involved tissue and fistula were removed, and the defect in the pelvic floor was closed by suturing after surgery. After 8 mo, the postoperative follow-up has been uneventful. CONCLUSION: ATD may be a differential diagnosis in sinus tract cases. Laparoscopy combined with open surgery is a viable treatment option.

Excessive proliferation and apoptosis of parathyroid cells contribute to primary hyperparathyroidism in rabbit model.

To explore the molecular pathogenesis of primary hyperparathyroidism (PHPT), we investigated the proliferation and apoptosis of parathyroid cells in a rabbit model of diet-induced PHPT. A total of 120 adult Chinese rabbits were randomly divided into normal diet (Ca:P, 1:0.7) group (control group) or a high-phosphate diet (Ca:P, 1:7) group (experimental group). The thyroid and parathyroid complexes were harvested for 1-month interval from month 1 to month 6. The expression of proliferation markers, including proliferating cell nuclear antigen (PCNA) and cyclin-D1, and B cell lymphoma-2 (Bcl-2), were evaluated by immunohistochemistry in thyroid and parathyroid tissues. Apoptosis was quantified by DNA-fragment terminal labeling. Our results demonstrated that parathyroid cells in the experimental group started proliferating from the end of the 2nd month, the expression of PCNA, Bcl-2, and cyclin-D1 were significantly higher in the PHPT group than those of the control group (p<0.05). Furthermore, the apoptosis index (AI) was positively correlated with the glandular cell count and expression of PCNA in the 6th month in the PHPT group. Overall, our results suggested that excessive proliferation and apoptosis of parathyroid cells may contribute to the pathogenesis of PHPT through PCNA-related, Bcl-2-related, and cyclin-D1-related pathways.

The impact of COVID-19 pandemic on the treatment of acute appendicitis in China.

OBJECTIVE: This research aims to analyze the impact of the novel coronavirus pandemic on the hospital visits of patients with acute appendicitis. METHODS: The retrospective analysis was designed to look at the treatment of acute appendicitis in the Department of General Surgery in Beijing Jishuitan Hospital before and during the COVID-19 pandemic (2019-2020). Data was analyzed by the numbers of patients, sex, age, onset time, fever or not, laboratory examination, imaging test, and treatment. And we analyzed the differences between the "pre-COVID group" and "during-COVID group". RESULTS: Compared with the year 2019, the number of acute appendicitis patients has diminished substantially during the COVID-19 pandemic (2020), but the number elevated with the control of the pandemic. Even if we did not find the differences of the treatment before and during the pandemic (P = 0.932), the onset time to emergency was significantly longer (P < 0.001), and more patients had showed fever (P < 0.001) during the COVID-19 pandemic. And the total number of white blood cells and C reactive protein level were significantly higher in 2020 than those in 2019 (P = 0.006, 0.003). And the same result was found in patients with appendiceal fecalith (P = 0.047). CONCLUSION: During the pandemic of the new coronavirus pneumonia, the number of patients with acute appendix treatment dropped significantly, mainly because it took longer than before, and the condition was more severe. It can be seen that the new coronary pneumonia has a great impact on the patients' medical treatment behavior, and the active prevention and treatment of the new coronavirus pneumonia is currently an important and urgent issue.

Stercoral colonic diverticulum perforation with jejunal diverticulitis mimicking upper gastrointestinal perforation.

Stercoral perforation of the colon is an unusual pathological condition with fewer than 150 cases reported in the literature to date. We present a case of stercoral colonic perforation mimicking upper gastrointestinal perforation, which was diagnosed by computed tomography preoperatively. However, at laparotomy, stercoral colonic diverticulum perforation with jejunal diverticulitis became the most appropriate diagnosis.
