Persistent chronic calcific pancreatitis with intraductal calculi associated with secondary diabetes mellitus type 3 and diabetic ketoacidosis - A case report.

Diabetes mellitus type 3 refers to diabetes secondary to an existing disease or condition of the exocrine pancreas and is an uncommon cause of diabetes occurring due to pancreatogenic pathology. It accounts for 15-20% of diabetic patients in Indian and Southeast Asian continents. This is case report of a rare case of type 3 diabetes mellitus (T3DM) presenting with diabetic ketoacidosis (DKA). The patient was admitted for DKA along with complaint of hyperglycemia, blood glucose of 405 mg/dl with HbA1c level of 13.7%. Computed tomography evidence revealed chronic calcific pancreatitis with intraductal calculi and dilated pancreatic duct.

Giant stone adhered in the vaginal cavity in a female patient with type 2 diabetes mellitus: a case report.

BACKGROUND: Bladder lithiasis comprises 5% of urological lithiasis. Large bladder stones associated with vesicovaginal fistulas are rare, and the risk factors are not an isolated process. There are metabolic comorbidities associated with this pathology, including diabetes mellitus. CASE PRESENTATION: A 70-year-old Mestizo patient is presented, reporting dysuria, pollakiuria, and abdominal pain of 4 months of evolution, located in the hypogastric region, also with a sensation of a foreign body in the vaginal introitus. In her pathological history, she presented type 2 diabetes mellitus. A computed tomography scan of the abdomen and pelvis was performed, reporting a tumor lesion in the abdominal wall. Therefore, surgical intervention was performed by cystolithotomy, obtaining a giant stone adhered to the vaginal wall with a size of 10 cm × 12 cm. CONCLUSION: Early detection of this pathology should be exhaustive in patients with characteristics and comorbidities associated with stone development to avoid possible complications, such as vesicovaginal fistulas.

Predictors of persistent pain after extracorporeal shockwave lithotripsy for painful chronic calcific pancreatitis.

BACKGROUND: Extracorporeal shockwave lithotripsy (ESWL) and/or endoscopic retrograde cholangiopancreatography (ERCP) are recommended as first-line therapy for painful uncomplicated chronic pancreatitis with obstructed main pancreatic duct (MPD) in the pancreas head/body. However, predictors of pain relief after ESWL are unknown. We evaluated independent predictors of persistent pain in patients who underwent ESWL for chronic pancreatitis. METHODS: 640 consecutive adult patients with chronic pancreatitis, who underwent successful ESWL with ERCP and pancreatic duct (PD) stent placement, were followed for 12 months. The pain was assessed at baseline and at 12 months using the Izbicki Pain Score, with a score decrease of >50% considered pain relief. Independent predictors of pain relief were derived from logistic regression analysis. RESULTS: Of 640 patients (mean age 36.71 [SD 12.19] years; 60.5% men), 436 (68.1%) had pain relief and 204 (31.9%) had persistent pain. On univariate analysis, older age, male sex, alcohol and tobacco intake, longer duration of symptoms, dilated MPD and MPD stricture were associated with persistent pain at 12 months (P<0.05). Consumption of alcohol (odds ratio [OR] 1.93, 95%CI 1.26-2.97), tobacco (OR 4.09, 95%CI 2.43-6.90), duration of symptoms (OR 1.02, 95%CI 1.01-1.04), MPD size (OR 1.22, 95%CI 1.11-1.33), and MPD stricture (OR 8.50, 95%CI 5.01-14.42) were independent predictors of persistent pain. CONCLUSIONS: Alcohol, tobacco, duration of symptoms, MPD size and stricture were independent predictors of persistent pain after successful ESWL. A multidisciplinary team approach that includes behavioral therapy and surgical options should be considered for such patients.

Dacryolithogenesis or Dacryolithiasis-The Story So Far.

The term dacryoliths refers to the concretions found within the lacrimal system. When the term dacryoliths is unspecified, it usually refers to the noninfectious dacryoliths commonly isolated from the lacrimal sac and the nasolacrimal duct. More often, they are diagnosed incidentally during a dacryocystorhinostomy, and the reported incidence among all dacryocystorhinostomy surgeries is 5.7% to as high as 18%. Dacryolithiasis is a complex process occurring within the lacrimal system, and current evidence suggests a multifactorial etiology. The sequence of events can be summarized broadly into 4 stages: stage of susceptibility, stage of initiation/trigger, stage of development, and stage of maintenance. The triggering event is the breach of the lacrimal sac or nasolacrimal duct epithelium, resulting in microtrauma with blood leakage. The blood clots act as a nidus for subsequent sequential laying of mucopeptides, cellular debris present locally, debris washed from the ocular surface, and extraneous agents in tears. This process is aided by altered rheology and composition of the tear film. After the formation of dacryoliths, extracellular neutrophil traps usually form on the surface, which help to maintain the dacryoliths (which do not dissolve). This review highlights and discusses the possible sequence of events during dacryolithiasis.

Essentials of Computed Tomography Imaging of Hematuria.

Hematuria is defined usually as the presence of blood in the urine, either on voiding or in a catheterized specimen. Hematuria is broadly divided into microscopic and gross hematuria and may be symptomatic or asymptomatic. The causes of hematuria include a very wide spectrum of conditions. However, here, we have filtered the causes causing gross hematuria, including calculus, trauma, tumors, vascular, and miscellaneous causes. Plain X-rays of the kidney, ureter, and bladder; ultrasound; intravenous urography; computed tomography (CT); magnetic resonance imaging; retrograde ureterography and pyelography (RGP); cystoscopy; and ureteroscopy are techniques that are useful for diagnosis. In the past, one or a combination of several techniques was used to evaluate hematuria but recently, advances in CT urography mean that it can be used alone for this task. This article briefly reviews the common causes of gross hematuria in adults and their evaluation by CT-based urography. Gross hematuria is evaluated well with CT scan urography which includes an unenhanced scan, the nephrographic phase, and the excretory phase. Unenhanced scans are routinely performed to evaluate the basic parameters such as the size, shape, position, and outline of the kidneys and calculus disease, which is the most common cause of hematuria. Renal parenchymal diseases including masses are best visualized in the nephrographic phase along with other abdominal organs. Delayed excretory phases including the kidneys, ureters, and bladder are useful for detecting urothelial diseases. CT urography's protocol permits evaluations of hematuria through a single examination.

OBSTRUCTIVE UROPATHY FROM BILATERAL URETERIC CALCULI IN AN INFANT WITH DIARRHOEA DISEASE.

Introduction: Urolithiasis is the presence of mineral deposits in the urinary tract. It is rare in under-5 children and in Sub-Saharan Africa. Although metabolic abnormality is implicated in 50% of cases, infection, decreased urine volume and flow (dehydration state) have been implicated. We report a case of bilateral ureteric calculi in an infant with diarrhoea disease and dehydration. Case Report: A.S, is an 8-month-old male with prolonged loose, large-volume stool, large-volume vomiting, high-grade fever, body weakness, and peri-orbital swelling that progressed to generalized body swelling and absent urine for 2 days. He was conscious, afebrile (36.90C), pale with anasarca. Had distended abdomen with ascites. Dyspnea, coarse crepitation, and hypoxemia. Tachycardia (PR -180/min) Hypertensive (BP - 125/79mmHg). PCV - 20%, WBC - 24,000/l, platelet - 110,000/l. Creatinine (1030 umol/l), Urea - 30mmol/l, Multi drug resistant E.Coli. Bilateral Grade II nephritis, hydro-uretero-nephrosis, right pelvi-ureteric and left vesico-ureteric junction calculi. Managed for Diarrhoea disease complicated with Bilateral Obstructive uropathy secondary to Bilateral Ureteric Calculi. Had bilateral open ureteric exploration, ureterolithotomy, Stenting, intraoperative transfusion, antibiotics, analgesics, and IVF. 24-hr post-surgery: urine output (3.26ml/kg/hr): right stent (210ml), left stent (423ml) while urethral catheter (150ml), 742umol/l, Urea: 26mmol/l 48-hr post-surgery: Urine output 5.1ml/kg/hr (1224ml/24hr); Cr: 424umol/l, Urea: 16mmo/l 5 days post-surgery: Urine output 3.1ml/kg/hr (725ml/24hr); Cr: 47umol/l, Urea: 4.6 mmo/l, Patient was discharged home and currently on follow-up in paediatric nephrology and urology clinics. Conclusion: A high index of suspicion of obstructive uropathy in children with diarrhoea disease, and dehydration, who have developed acute kidney injury is recommended.

[Effect of pancreatic extracorporeal shock wave lithotripsy on chronic pancreatitis stones].

Objective: To analyze the therapeutic effect and safety of pancreatic extracorporeal shock wave lithotripsy(P-ESWL) for patients with chronic pancreatitis complicated by stones of the pancreatic duct and to investigate the influencing factors. Methods: A retrospective analysis was performed on clinical data from 81 patients with chronic pancreatitis complicated by pancreatic duct calculus treated with P-ESWL in the Department of Hepatobiliary Surgery, the First Affiliated Hospital of Xi 'an Jiaotong University from July 2019 to May 2022. There were 55 males(67.9%) and 26 females(32.1%). The age was (47±15)years (range: 17 to 77 years). The maximum diameter(M(IQR)) of the stone was 11.64(7.60) mm, and the CT value of the stone was 869 (571) HU. There were 32 patients (39.5%) with a single pancreatic duct stone and 49 patients(60.5%) with multiple pancreatic duct stones. The effectiveness, remission rate of abdominal pain, and complications of P-ESWL were evaluated. Student's t test, Mann Whitney U test, χ2 test, or Fisher's exact test was used to compare the characteristics between the effective and ineffective groups of lithotripsy. The factors influencing the effect of lithotripsy were analyzed by univariate and multivariate logistic regression analysis. Results: Eighty-one patients with chronic pancreatitis were treated with P-ESWL 144 times, with an average of 1.78 (95%CI:1.60 to 1.96) times per person. Among them, 38 patients(46.9%) were treated with endoscopy. There were 64 cases(79.0%) with effective removal of pancreatic duct calculi and 17 cases(21.0%) with ineffective removal. Of the 61 patients with chronic pancreatitis accompanied by abdominal pain, 52 cases(85.2%) had pain relief after lithotripsy. After lithotripsy treatment, 45 patients(55.6%) developed skin ecchymosis, 23 patients(28.4%) had sinus bradycardia, 3 patients(3.7%) had acute pancreatitis, 1 patient(1.2%) had a stone lesion, and 1 patient(1.2%) had a hepatic hematoma. Univariate and multivariate logistic regression analysis showed that the factors affecting the efficacy of lithotripsy included the age of patient(OR=0.92, 95%CI: 0.86 to 0.97), the maximum diameter of the stone(OR=1.12,95%CI:1.02 to 1.24) and the CT value of the stone(OR=1.44, 95%CI: 1.17 to 1.86). Conclusions: P-ESWL is effective in the treatment of patients with chronic pancreatitis complicated by calculi of the main pancreatic duct.Factors affecting the efficacy of lithotripsy include patient's age, maximum stone diameter, and CT value of calculi.

An overlooked complication of the clean intermittent catheters: prostate calculi.

OBJECTIVE: Although the clinical importance of prostate calculi has been understood over time, it is a urinary system disease that can cause different symptoms and can be ignored by urologists sometime. Clean intermittent catheter (CIC) is the gold standard method for bladder rehabilitation and urinary drainage in patients with neurogenic bladder. The aim of this study was to compare the incidence of prostate calculi and related pathologies between patients using CIC and not using CIC. MATERIAL-METHOD: A total of 314 neurogenic bladder patients who were followed up and treated in our urology clinic were included in this study. The patients were divided into two groups as patients non-using CIC (Group-1, n:154) and patients using CIC (Group-2, n:160).Presence of prostate calculi, the number of CIC used per/day, plasma uric acid levels, urine parameters, mean-stone-density (MSD) and calculi sizes were retrospectively scanned from patient records. RESULTS: In this study, no significant difference was observed between the parameters such as age, uric acid level, MSD, urine parameters, and other electrolyte levels (Table 1) While the incidence of prostate calculi in Group 1 was 23.4%; The incidence of prostate calculi in group 2 was 37.5(p = 0.007) (Fig. 2). CONCLUSiON: In this study, it was tried to show the relationship between the use of CIC and prostate calculi that cause LUTS and dysuria, which are generally ignored in clinical evaluation but do not pass in patients. As a result of this study, it was determined that the incidence of prostate calculi increased in patients using CIC.

Enterolith Treated with a Combination of Double-Balloon Endoscopy and Cola Dissolution Therapy.

A 71-year-old woman with rheumatoid arthritis who had been taking NSAIDs for many years consulted our hospital for abdominal pain. She was diagnosed with a small bowel obstruction due to an enterolith according to an abdominal CT scan that showed dilation from the enterolith in the small intestine on the oral side. It was considered that the intestinal stone was formed due to stagnation of intestinal contents and had gradually increased in size, resulting in an intestinal obstruction. We performed antegrade double-balloon endoscopy (DBE) to observe and remove the enterolith. We used forceps and a snare to fracture the enterolith. During this attempt, we found a seed in the center of the enterolith. Since the intestinal stone was very hard, cola dissolution therapy was administered from an ileus tube for 1 week. The following week, DBE was performed again, and it was found that the stone had further softened, making attempts at fracture easier. Finally, the enterolith was almost completely fractured. Intestinal stenosis, probably due to ulcers caused by NSAIDs, was found. Small bowel obstruction with an enterolith is rare. In this case, it was considered that the seed could not pass through the stenotic region of the small intestine and the intestinal contents had gradually built up around it. It has been suggested that DBE may be a therapeutic option in cases of an enterolith. Further, cola dissolution therapy has been shown to be useful in treating an enterolith, with the possible explanation that cola undergoes an acid-base reaction with the enterolith. In summary, we report, for the first time, treatment of an enterolith with a combination of DBE and cola dissolution therapy, thereby avoiding surgery and its risks.

Digital single-operator pancreatoscopy for the treatment of symptomatic pancreatic duct stones: a prospective multicenter cohort trial.

BACKGROUND: Digital single-operator pancreatoscopy (DSOP)-guided lithotripsy is a novel treatment modality for pancreatic endotherapy, with demonstrated technical success in retrospective series of between 88 % and 100 %. The aim of this prospective multicenter trial was to systematically evaluate DSOP in patients with chronic pancreatitis and symptomatic pancreatic duct stones. METHODS: Patients with symptomatic chronic pancreatitis and three or fewer stones ≥ 5mm in the main pancreatic duct (MPD) of the pancreatic head or body were included. The primary end point was complete stone clearance (CSC) in three or fewer treatment sessions with DSOP. Current guidelines recommend extracorporeal shock wave lithotripsy (ESWL) for MPD stones > 5 mm. A performance goal was developed to show that the CSC rate of MPD stones using DSOP was above what has been previously reported for ESWL. Secondary end points were pain relief measured with the Izbicki pain score (IPS), number of interventions, and serious adverse events (SAEs). RESULTS: 40 chronic pancreatitis patients were included. CSC was achieved in 90 % of patients (36/40) on intention-to-treat analysis, after a mean (SD) of 1.36 (0.64) interventions (53 procedures in total). The mean (SD) baseline IPS decreased from 55.3 (46.2) to 10.9 (18.3). Overall pain relief was achieved in 82.4 % (28/34) after 6 months of follow-up, with complete pain relief in 61.8 % (21/34) and partial pain relief in 20.6 % (7/34). SAEs occurred in 12.5 % of patients (5/40), with all treated conservatively. CONCLUSION: DSOP-guided endotherapy is effective and safe for the treatment of symptomatic MPD stones in highly selected patients with chronic pancreatitis. It significantly reduces pain and could be considered as an alternative to standard ERCP techniques for MPD stone treatment in these patients.

Are Newer Extracorporeal Shock Wave Lithotripsy Models Truly Improving Pancreatolithiasis Lithotripsy Performance? A Japanese Single-Center Study Using Endoscopic Adjunctive Treatment.

Background/Aims: Many Japanese institutions use electromagnetic extracorporeal shock wave lithotripsy (ESWL) systems for treating pancreatic duct stones. However, there are no reports on direct comparisons between recent electromagnetic lithotripters. This study aimed to verify whether the new electromagnetic lithotripter can improve the efficiency of pancreatic stone fragmentation, and to clarify the role of combined endoscopic treatment on the clearance of pancreatic duct stones. Methods: We retrospectively identified 208 patients with pancreatolithiasis who underwent endoscopic adjunctive treatment after pancreatic ESWL at a single Japanese center over a 17-year period. We evaluated the outcome data of this procedure performed with SLX-F2 (last 2 years; group A) and Lithostar/Lithoskop (first 15 years; group B), as well as additional endoscopic treatments for pancreatolithiasis. We also performed logistic regression analysis to detect various factors associated with the procedure. Results: For pancreatic head stones, ESWL disintegration was achieved in 93.7% of group A patients and 69.0% of group B patients (p=0.004), and adjunctive endoscopic treatment removed stones in 96.8% of group A patients and 73.0% of group B patients (p=0.003). Multivariate analysis revealed that lithotripter type (odds ratio, 6.99; 95% confidence interval, 1.56 to 31.33; p<0.01) and main pancreatic duct stricture (odds ratio, 2.87; 95% confidence interval, 1.27 to 6.45; p<0.01) were significant factors for ESWL fragmentation. Conclusions: The SLX F2 showed high performance in fragmenting the pancreatic duct stones. In addition, endoscopic adjunctive treatment improved the overall success rate of the procedure. The improved ESWL lithotripter has many advantages for patients undergoing pancreatic lithotripsy treatment.

Per-oral pancreatoscopy-guided lithotripsy vs. extracorporeal shock wave lithotripsy for treating refractory main pancreatic duct stones in chronic pancreatitis: Protocol for an open-label multi-center randomized clinical trial.

BACKGROUNDS/OBJECTIVES: Patients with chronic pancreatitis may develop pancreatic duct stones that can obstruct outflow leading to ductal hypertension and pain. Both endoscopic retrograde pancreatography (ERP) with per-oral pancreatoscopy (POP) and intraductal lithotripsy and extracorporeal shock wave lithotripsy (ESWL) are feasible options to attempt ductal stone clearance. This study aims to compare POP-guided lithotripsy with ESWL in the management of refractory symptomatic main pancreatic duct stones. METHODS: This is an open-label, multi-center, parallel, randomized clinical trial. Patients with chronic pancreatitis and main pancreatic duct stones ≥5 mm who fail standard ERP methods for stone removal will be eligible for this study. In total, 150 subjects will be randomized 1:1 to either ESWL or POP. A maximum of 4 sessions of either ESWL or POP will be allowed in each arm, with crossover permitted thereafter. The primary outcome is complete stone clearance and secondary outcomes include quality of life, pain scores, number of interventions, and daily opiate requirements. CONCLUSIONS: This study aims to answer the question of which lithotripsy method is superior in removing refractory pancreatic duct stones while addressing the effects of lithotripsy on quality of life and pain in patients with chronic calcific pancreatitis (ClinicalTrials.gov NCT04115826).

The Visceral-to-subcutaneous Adipose Tissue Area Ratio Is Associated with Retreatment in Chronic Pancreatitis Patients with Pancreatolithiasis after Extracorporeal Shock Wave Lithotripsy.

Objective Extracorporeal shock wave lithotripsy (ESWL) has been used to treat pancreatolithiasis in patients with chronic pancreatitis (CP), but the high recurrence rate remains challenging. We therefore evaluated the association between body composition parameters and the prediction of retreatment after ESWL. Methods This study retrospectively evaluated 42 patients with CP who had been treated with ESWL between 2008 and 2019 in a single center. Body composition parameters were measured on pretreatment computed tomography images. Patients who underwent repeat ESWL were classified as the retreatment group. Results There were 13 (31.0%) and 29 (69.0%) patients in the retreatment and non-retreatment groups, respectively. The visceral-to-subcutaneous adipose tissue area ratio (VSR) of the retreatment group was significantly lower than that of the non-retreatment group (p=0.016). When divided by the median VSR, 10 of the 20 patients with a VSR of <0.85 underwent retreatment, whereas 3 of the 22 patients with a VSR of ≥0.85 underwent retreatment (p=0.019). According to a multivariate analysis, the VSR (p=0.010) and age (p=0.037) were independent factors associated with retreatment after ESWL. Conclusion This study showed that the VSR can predict the retreatment of patients with CP after ESWL.

[A case of obstructive jaundice due to the movement of pancreatic calculi].

A 44-year-old man with a history of chronic alcoholic pancreatitis and Crohn's disease presented with abdominal pain. Computed tomography revealed pancreatic calculi in the head of the pancreas and a dilated pancreatic duct. The patient was diagnosed with an acute exacerbation of chronic pancreatitis due to the impact of pancreatic calculi on the main pancreatic duct. During the clinical course, the movement of pancreatic calculi to the major papilla was confirmed, leading to obstructive jaundice. Endoscopic treatment with sphincterotomy of the pancreatic duct was successful. Herein, we report the case of an unusual clinical course involving obstructive jaundice caused by the movement of pancreatic calculi.

Large Meckel's Diverticulum Enterolith. A case of small bowel obstruction.

The Meckel's diverticulum is usually asymptomatic but in sometimes it presents severe complications, such as bleeding or perforation. The presence of enterolith inside a Meckel diverticulum is rare. In this report, we present a case of a 56- years- old man, with an abdominal pain and small bowel obstruction for a enterolith. Preoperative radiologic studies in Emergency Room (ER) didn't reveal this stone, but realeved a small bowel obstruction. Initially, we tried a conservative management, however after about 48 hours, due to worsening symptoms, the patient undergoes an exploratory laparotomy and a intestinal resection. Key words: Enteriith, Meckel's diverticulum, Small bowel obstruction.

Pancreatic Stones: Clinical Outcomes With Nonsurgical Treatment in a Japanese Single-Center Study.

OBJECTIVES: While chronic pancreatitis associated with pancreatolithiasis presents with pain, exocrine and endocrine pancreatic functions worsen with time. We examined outcomes of nonsurgical treatment. METHODS: Between 1992 and 2020, we treated pancreatolithiasis nonsurgically in 165 patients with chronic pancreatitis using extracorporeal shock wave lithotripsy alone or followed by endoscopic procedures. The mean follow-up duration was 49 months (standard deviation, 56 months) and the age was 56 years (standard deviation, 13 years). The male:female ratio was 5.1:1 (138 men, 27 women). We followed treatment results including relief of abdominal pain, stone clearance and recurrence, and pancreatic exocrine function (bentiromide-p-aminobenzoic acid testing). RESULTS: Treatment relieved pain in 117 of 124 patients (94%). The overall stone clearance was achieved in 130 of 165 patients (79%). Stones recurred during follow-up in 50 of 130 patients (38%). One fifth of recurrences were early, often involving stricture of the main pancreatic duct. After 1 year, 65% of the patients had improved or stable exocrine function. CONCLUSIONS: Nonsurgical stone removal usually improved symptoms and preserved pancreatic exocrine function. Nonsurgical treatment with extracorporeal shock wave lithotripsy followed by endoscopic treatment if needed is useful as initial management for pancreatolithiasis.
