A 15-year-old female patient presented to emergency with bilious vomiting after taking meals for the last 3 months along with intermittent colicky pain in the epigastrium for the last 1 month. Initially, the frequency of vomiting was 2–3 times/week which gradually increased to 4–5 times/day in the last 2 weeks. She had no history of any abdominal pathology or past history of tuberculosis or abdominal surgery. A review of systems showed she had a weight loss of about 10 kgs in the last 3 months along with loss of appetite. Physical examination revealed soft distention of the upper abdomen with mild tenderness in the epigastrium. CT scan of the abdomen showed concentric heterogenous luminal narrowing near duodenojejunal flexure with gross dilatation of the duodenum and stomach. The patient underwent resection of D4 and proximal jejunum with side-to-side D2-jejunum anastomosis. Histopathological examination revealed the luminal lesion to be an adenocarcinoma.

Background: Internal hernia (IH) after laparoscopic colorectal surgery is a potentially severe complication. It may go undiagnosed in patients having their abdominal CT scan during oncologic follow-up. We evaluated the occurrence of IH on CT scans after laparoscopic curative resection for rectal cancer (LRRC) and routine closure of the mesenteric defect. Methods: Data from 189 consecutive patients undergoing elective curative LRRC in a 14-year period (June 2005-june 2019) were prospectively collected. Only patients with abdominal CT scans, performed as routine oncologic follow-up, between 3 months and 7 years post-operatively were included in the study and reviewed by a surgeon and a radiologist. Results: A total of 161 patients were eligible for the study with a median age of 69 years (IQR: 59–77) at surgery. They had abdominal follow-up CT scans at a median of 39.5 months (IQR: 12.8–62.7) after surgery. The prevalence of IH was 11.2% (18/161 patients). Of the 18 patients, 15 (83.3%) were fully asymptomatic, 2 (11.1%) reported chronic abdominal discomfort (including mostly nausea and colicky pain) during their oncologic follow-up (however, IH was not suspected neither prompted additional investigations), and 1 (5.6%) was reoperated elsewhere for IH and acute small bowel obstruction. Conclusions: IH following LRRC is not uncommon, with a prevalence > 10% in our experience. Most of these patients remain fully asymptomatic, but in a few patients, IH might be responsible for some symptoms or require reoperation. Awareness of this complication is important, given the potential risk of acute small bowel obstruction. [ABSTRACT FROM AUTHOR]

In advanced cancer patients with inoperable bowel obstruction, the administration of antisecretive and antiemetic drugs has proved to be effective in controlling gastrointestinal symptoms caused by bowel obstruction. However, controlled studies concerning the most effective antisecretive drug are lacking. The aim of this randomized controlled study was to determine whether octreotide or hyoscine butylbromide was the more effective antisecretive drug for use in states of inoperable bowel obstruction. Eighteen patients with inoperable bowel obstruction randomly received octreotide 0.3 mg daily ( n=9) or hyoscine butylbromide (HB) 60 mg daily ( n=9) s.c. The following parameters were measured: episodes of vomiting, nausea, drowsiness, continuous and colicky pain, using a Likert scale corresponding to a numerical value: (none 0, slight 1, moderate 2, severe 3) recorded before starting the treatment (T0) and 24 h (T1), 48 h (T2) and 72 h after (T3), and the mean daily amounts of fluids administered i.v. or s.c. during the period of study. Three patients dropped out of the study because data were incomplete. Octreotide treatment induced a significantly rapid reduction in the number of daily episodes of vomiting and intensity of nausea compared with HB treatment at the different time intervals examined. No relevant changes were found in dry mouth, drowsiness and colicky pain. Lower levels of hydration were associated with nausea regardless of the treatment. At the doses used in this study, octreotide was more effective than HB in controlling gastrointestinal symptoms of bowel obstruction. Further studies are necessary to understand the role of hydration more clearly in such a clinical situation. [ABSTRACT FROM AUTHOR]

In Germany, analyses of clinical and laboratory features of patients with acute porphyrias are only available for hereditary coproporphyria (HCP) but not with other acute porphyrias, acute intermittent porphyria (AIP) and variegate porphyria (VP). The aim of the study was to analyze a large cohort of patients with particular focus upon quality of life aspects. Sixty-two individuals from separate families with acute porphyrias (57 AIP, 5 VP) were included into an observational study collecting biochemical, genetic, and clinical data. A questionnaire was designed to complete anamnestic information and to assess the influence on quality of life. Most frequent signs and symptoms or laboratory abnormalities were abdominal colicky pain, red coloration of urine, and hyponatremia. Depression or anxiety was reported by 61% or 52% individuals, respectively. Fatigue was mentioned as the most quality of life-limiting symptom. In 59/61 patients, mutations could be identified. 44% (20/45) had to be admitted to an intensive care unit. Heme arginate was used in 64% (29/45) of patients for treatment of acute attacks at least once and in 33% for long-term treatment with high frequency of administration. Serum creatinine values increased in 47% (7/17) of the patients with recurrent attacks. Our analysis confirms a substantial influence of the diseases on the quality of life on patients. Percentages of urine discoloration and intensive care unit admissions were much higher than in other reports. Long-term treatment with heme arginate requires careful monitoring of iron status and renal values. [ABSTRACT FROM AUTHOR]

An inflammatory myofibroblastic tumor (IMT) of the ileum is a very rare lesion of the gastrointestinal tract. A 36-year-old female presented with abdominal fullness and colicky pain of 5 days' duration. Plain abdominal radiography showed an intestinal obstruction with dilated jejunal loops. Abdominal computed tomography and ultrasonography demonstrated a well-defined intraluminal solid mass surrounded by the typical mural layers of an invaginated ileum. The patient then underwent an exploratory laparotomy under a clinical diagnosis of intussusception caused by a small bowel tumor. The surgical findings revealed a large mass leading to an ileoileal intussusception, with regional lymph node enlargement and a small bowel resection accompanied by lymph node dissection was performed. The definitive diagnosis of IMT was confirmed by both conventional histopathology and minute immunohistochemistry. [ABSTRACT FROM AUTHOR]

Background. An exclusively breast-fed 8-week-old boy presented with irritability and non-bilious projectile vomiting. He was referred to our Medical Imaging Department to eliminate pyloric stenosis.¶Patient and methods. A diagnosis of colitis was strongly suggested by ultrasound. A more detailed history revealed that the patient also had episodes of colicky pain and bloody stools. An infectious colitis was subsequently excluded and rectal biopsy supported the diagnosis of allergic proctocolitis.¶Results. The infant responded well to the withdrawal of cow's milk and dairy products from the maternal diet.¶Conclusion. Allergic proctocolitis should be included in the differential diagnosis of infants presenting with vomiting and/or bloody stools. [ABSTRACT FROM AUTHOR]

A 54-yr-old man with multiple metastatic liver cancer was admitted to our hospital because of melena and intermittent colicky pain on the right upper abdomen. He underwent partial gastrectomy for gastric cancer 3 yr before the admission. Endoscopic examination of the duodenum on the 3rd hospital day showed active bleeding from the papilla of Vater, and diagnosis of hemobilia was done. Transcatheter arterial embolization controlled the bleeding successfully, and no rebleeding occurred until his death due to the advanced cancer 8 months later. We considered that the high vascularity of his metastatic tumor caused hemobilia. To the best of our knowledge, this is the first report of hemobilia by metastatic liver cancer treated successfully with transcatheter arterial embolization. [ABSTRACT FROM AUTHOR]

Purpose: Choledochoduodenostomy (CDD) is performed to treat choledocholithiasis (CDL) cases where endoscopic stone removal is difficult. Recognizing CDD characteristics is important for CDL treatment planning. Methods: A total of 116 patients, including 33 patients ≥ 80 years old (29 with previous total gastrectomy, 19 with previous distal gastrectomy, 20 with built-up stones, 19 with periampullary diverticulum, 10 with confluence stones, 8 with repetitive recurrent stones, 4 with hard stones, 3 with endoscopic retrograde cholangiography [ERC] not available due to lack of cooperation, 2 with a history of pancreatitis post-ERC, and 2 in whom ERC could not be performed due to a disturbed anatomy) underwent CDD for CDL. Postoperative complications and long-term outcomes were evaluated. Results: The in-hospital mortality rate was 0%. The morbidity (grade ≥ IIIA according to the Clavien–Dindo classification) rates in the elderly (≥ 80 years old) and non-elderly (51–79 years old) patients were 3.0% (1/33) and 2.4% (2/83), respectively (p = 0.85). Long-term complications included cholangitis in eight (7%) patients, of which three cases were repetitive and seven had an operative history of total or distal gastrectomy. The incidence of postoperative cholangitis after total or distal gastrectomy was 15% (7/48), which was significantly higher than that involving other causes (1.5%, 1/68; p < 0.01). Two patients with cholangitis after total gastrectomy experienced early recurrence of lithiasis at 2 and 9 months after surgery. Conclusions: CDD is safe, even in elderly patients. However, a history of total gastrectomy or distal gastrectomy may increase the incidence of postoperative cholangitis. [ABSTRACT FROM AUTHOR]

The HIV protease inhibitor indinavir may cause nephrolithiasis and interstitial nephritis. The renal consequences of indinavir-associated nephrotoxicity are uncertain. We report a case of papillary necrosis in a patient treated with indinavir. An asymptomatic HIV-infected woman experienced rightsided renal colicky pain during treatment with indinavir. She passed a non-solid stone and continued indinavir treatment. Intravenous pyelogram performed 20 months later following an episode of left-sided colicky pain showed right-sided papillary necrosis. Indinavir-associated nephrolithiasis and chronic interstitial nephritis were the only possible causes identified in this patient. Physicians should be aware that indinavir nephrolithiasis may cause papillary necrosis. [ABSTRACT FROM AUTHOR]

Wandering spleen is a very rare condition, it is characterized by the absence or weakness of one or more of the ligaments that hold the spleen in its normal position in the left hypochondrium. The disorder is not genetic in origin. Instead of ligaments, the spleen is attached by a stalk-like tissue supplied with blood vessels (vascular pedicle). If the pedicle is twisted in the course of the movement of the spleen, the blood supply may be interrupted or blocked (ischemia) to the point of severe damage to the blood vessels (infarction). Because there is little or nothing to hold it in place the spleen 'wanders' in the lower abdomen or pelvis where it may be mistaken for an unidentified abdominal mass. 'Acquired' wandering spleen may occur during adulthood due to injuries or other underlying conditions that may weaken the ligaments that hold the spleen in its normal position (e.g., connective tissue disease or pregnancy). We here report a case of 40-year-old woman presented to the surgical emergency department, with complaints of colicky abdominal pain of 8 h duration with increasing severity and bilious vomiting. On examination, the patient well built, nourished, conscious, and coherent with profuse sweating. Vital signs were normal excepting high pulse rate of 120/min with blood pressure of 100/60. On examination, she has a central abdominal distention shifting to different quadrants with colicky pain with vague tender firm mass. Abdominal ultrasonography showed ectopic spleen around the umbilicus with variable echos and whorled appearance of the splenic vessels. The patient was prepared for emergency laparotomy. At laparotomy, the spleen was found just below the umbilicus and it was dusky enlarged with infarction with four anticlockwise twists of the long splenic pedicle in the central quadrant of the abdomen. Splenectomy was carried out as there was clear evidence of splenic ischemia after detorsion of the spleen. [ABSTRACT FROM AUTHOR]

We report 3 cases of benign retroperitoneal schwannoma, of whom one presented with flank pain with hematuria, one presented with headache and secondary hypertension and one presented with recurrent renal colicky pain. Two patients were treated by open surgical excision of the tumor with nephrectomy of the corresponding side because the tumors were densely adhered to the kidney and one case treated by laparoscopic resection of the mass only. The diagnosis of schwannoma was established postoperatively after histopathological examination and immunohistochemistry. All patients are doing well in follow-up. [ABSTRACT FROM AUTHOR]

An unusual clinical presentation of appendicitis with violent colicky pain as seen classically in urolithiasis is here presented. The pathophysiology of colic and the differential diagnosis of appendicolithiasis is briefly discussed. [ABSTRACT FROM AUTHOR]

Cancer pain is generally treated with pharmacological measures, relying on using opioids alone or in combination with adjuvant analgesics. Weak opioids are used for mild-to-moderate pain as monotherapy or in a combination with nonopioids. For patients with moderate-to-severe pain, strong opioids are recommended as initial therapy rather than beginning treatment with weak opioids. Adjunctive therapy plays an important role in the treatment of cancer pain not fully responsive to opioids administered alone (ie, neuropathic, bone, and visceral colicky pain). Supportive drugs should be used wisely to prevent and treat opioids' adverse effects. Understanding the pharmacokinetics, pharmacodynamics, interactions, and cautions with commonly used opioids can help determine appropriate opioid selection for individual cancer patients.

Angiomyolipoma usually present as incidental findings on routine imaging or laparotomy, but rarely they may give rise to massive hemorrhage. If bleeding occurs, the treatment of choice is to save life either by angiography with selective embolisation or surgery. Herein, we reported a case of a 32-year-old man who came to our hospital complaining of sudden colicky pain in the right hypochondria region, associated with nausea and vomiting. On physical examination, the patient was in a state of shock; blood pressure of 60/36 mmHg, heart rate of 160 beats/min, high abdominal distention, and non-coagulated blood was extracted from abdominal puncture. The abdominal computed tomography (CT) and arteriography showed a 20 × 15 × 15 cm mass suggestive of spontaneous rupture of liver neoplasm and intraperitoneal hemorrhage. On laparotomy, 1500 mL of non-coagulated blood was found, and the tumor located at right upper abdomen, which originated from retroperitoneum. The tumor was resected totally with hematoma and sutured the bleeding vessels. The histological study of the resected mass revealed the presence of angiomyolipoma. [ABSTRACT FROM AUTHOR]

The objective of this study is to assess the efficacy of an alpha-1 adrenergic receptor blocking agent on the spontaneous passage of proximal ureteral calculi ≤10 mm. 92 patients having single radio-opaque proximal ureteral stone ≤10 mm were randomized into two groups. Group 1 patients ( n = 50) were followed with classical conservative approach and patients in Group 2 ( n = 42) additionally received tamsulosin, 0.4 mg/day during 4 weeks follow-up. The stone passage rates, stone expulsion time, VAS score, change in colic episodes, and hospital re-admission rates for colicky pain were compared. The patients were furthermore stratified according to stone diameters <5 and 5–10 mm. The data of these subgroups were also compared. Stone expulsion rates showed statistically significant difference between tamsulosin receivers and non-receivers (35.7 vs 30%, p = 0.04). Time to stone expulsion period was also shortened in those receiving tamsulosin (8.4 ± 3.3 vs 11.6 ± 4.1 days, p = 0.015). Likewise, the mean VAS score and renal colic episodes during follow-up period were significantly diminished in Group 2 patients (4.5 ± 2.3 vs 8.8 ± 2.9, p < 0.01 and 66.6 vs 36%, p = 0.001, respectively). Among the stones <5 mm, tamsulosin receiving patients had higher spontaneous passage rate (71.4 vs 50%, p < 0.001). The prominent effect of tamsulosin on the 5–10 mm stones was the relocation of the stones to a more distal part of ureter (39.3 vs 18.7%, p = 0.001). Administration of tamsulosin in the medical management of proximal ureteral calculi can facilitate the spontaneous passage rate in the stone <5 mm and the relocation of the stones between 5 and 10 mm to more distal part of the ureter.

Acute severe colicky pain in the flank region is termed as renal colic (RC), which is commonly diagnosed and treated in the emergency department (ED). The present study is designed to investigate the hospital costs of patients with RC admitted to the ED and factors affecting the figures. Retrospective analysis includes all patients diagnosed with RC following physical examination and X-ray, ultrasound, computed tomography together with laboratory investigations in the university-based ED between February 2007 and February 2009. The study included 574 patients eligible for the predefined criteria. Mean total hospital cost in patients admitted to the ED due to RC was calculated to be 55.77 Euro. The greatest contribution to the total cost was made by radiological investigations in the ED (40.5%) followed by treatment costs (19.7%). Size and location of the stone and stay times in the ED were the independent variables affecting the costs. The costs were higher as the stones were bigger and as they were more distal in the ureter. Renal stones were associated with the lowest hospital costs. Radiological investigations are the greatest contributors in the ED costs in patients with RC. Effective measures need to be undertaken to reduce resultant costs. Preventive measures as well as diagnostic and therapeutic procedures should be standardized in the ED in accordance with technological advances and also cost-effectiveness when appropriate.

Abstract  Spontaneous intracholecystic bleeding is very rare. We report herein a very rare case of a pseudoaneurysm of the cystic artery due to acute cholecystitis. A 58-year-old man presented at the emergency department complaining of colicky pain in the right upper quadrant. Dynamic magnetic resonance imaging demonstrated an early-enhanced pooling of contrast material (suggestive of a pseudoaneurysm of the cystic artery) inside the neck of the gallbladder. After the proximal control of the hepatic artery, the patient underwent a cholecystectomy and a ligation of the cystic artery. The resected specimen of the gallbladder showed evidence of a massive intracholecystic hematoma. Proximal to the impacted gallstone in the neck, a 2-cm diameter saccular-type pseudoaneurysm was identified. Although a pseudoaneurysm of the cystic artery is very rare, it should be included in the differential diagnosis of hemobilia. Once the pseudoaneurysm is confirmed, its embolization before a cholecystectomy (which can be attempted laparoscopically) may be useful to ensure the safety of the patient. [ABSTRACT FROM AUTHOR]

Among the advantages of the One Anastomosis Gastric Bypass (OAGB) are the lack of jejuno-jejunal anastomosis and a supposed lower incidence of internal hernia (IH), with only a few cases reported until now. However, the incidence of IH after OAGB is not null. We present a video of the laparoscopic management of an IH that occurred after an OAGB. The patient was a 49-year-old female who had undergone a laparoscopic revisional OAGB 2 years previously after a failed laparoscopic adjustable gastric banding. She was referred to our Unit for recurrent postprandial colicky pain. She lost a total of 50 kg and her body mass index (BMI) dropped from 38 to 19 kg/m2. A CT scan with intravenous contrast showed a swirl of the mesentery around the superior mesenteric artery, without small bowel obstruction. A laparoscopic exploration was performed, confirming the suspicion of IH at the Petersen's space. An anticlockwise derotation of the whole common limb was performed, and the Petersen's space was eventually closed with a running non-absorbable suture. [ABSTRACT FROM AUTHOR]

Purpose of Review: In this study, we describe a rare case of a male with a duplex renal collecting system with ectopic ureter insertion into the prostate who presented with sepsis and required urgent laparoscopic radical nephrectomy. This study offers urologists and emergency care practitioners a great overview of the variety of manifestations, anatomic differences, and therapeutic approaches for similar patients. Recent Findings: modified reconstructive strategy could be a method of choice when addressing particular anatomies, such as incomplete duplex kidneys with ureteropelvic junction obstruction in both upper and lower poles when the obstruction is close to the confluence of the two ureters. Summary: There is a spectrum of acute presentations and management strategies in adult patients with duplex collecting systems. The majority of patients presenting with obstruction and infection are managed surgically with hemi-nephrectomy; stable patients who present with less extensive anomalies were managed conservatively or with ureteral dilatation or deroofing.

It is important to do a fast and effective treatment for patients with renal colic pain in emergency departments for both patients' comfort and clinicians' patient management. In this study, we aimed primarily to test the efficacy of intradermal sterile water application as a rapid and effective treatment in severe renal colic. This is a single-centre, prospective, randomised controlled trial. Study group consists of patients with severe renal colic related to urolithiasis. Patients were randomly divided into three groups. The first group received only intramuscular diclofenac sodium, the second group received intramuscular diclofenac sodium and intradermal sterile water, and the third group received intramuscular diclofenac sodium together with intravenous fentanyl. Numerical Rating Scale was used to determine the level of pain before and after the treatment at the 1st, 5th, 15th, 30th, 60th and 120th minutes. 95 out of 201 patients with severe renal colic pain randomly divided into 3 groups. The pre-treatment pain severity of the groups was similar (p = 0.228). We found that the decrease in pain intensity was significantly faster in the intradermal sterile water group than the other groups even in the first minute. Percentages of patients who had 50% pain reduction, which is considered as successful treatment, was higher in the intradermal sterile water group (which had 75.9% success rate) in the first 5 min compared to the IM diclofenac sodium group (which had 7.1% success rate) and IV fentanyl group (which had 25% success rate) (p < 0.001). According to the results, pain control was achieved much faster than the other methods with intradermal sterile water injection. All methods were found to be effective in relieving the pain of the patients. [ABSTRACT FROM AUTHOR]

About 20% of adults worldwide have gallstones which are solid conglomerates in the biliary tree made of cholesterol monohydrate crystals, mucin, calcium bilirubinate, and protein aggregates. About 20% of gallstone patients will definitively develop gallstone disease, a condition which consists of gallstone-related symptoms and/or complications requiring medical therapy, endoscopic procedures, and/or cholecystectomy. Gallstones represent one of the most prevalent digestive disorders in Western countries and patients with gallstone disease are one of the largest categories admitted to European hospitals. About 80% of gallstones in Western countries are made of cholesterol due to disturbed cholesterol homeostasis which involves the liver, the gallbladder and the intestine on a genetic background. The incidence of cholesterol gallstones is dramatically increasing in parallel with the global epidemic of insulin resistance, type 2 diabetes, expansion of visceral adiposity, obesity, and metabolic syndrome. In this context, gallstones can be largely considered a metabolic dysfunction-associated gallstone disease, a condition prone to specific and systemic preventive measures. In this review we discuss the key pathogenic and clinical aspects of gallstones, as the main clinical consequences of metabolic dysfunction-associated disease. [ABSTRACT FROM AUTHOR]

We reported a case of ureteric tumor, an uncommon disease presenting with colonic obstruction. This 52-year-old lady presented with history of colicky pain left lower abdomen for 5 months. Colonoscopy revealed circumferential nonnegotiable stricture at 25 cm from anal verge, and colonoscopic biopsy was inconclusive. Contrast-enhanced computed tomography (CECT) showed a growth involving sigmoid colon and left ureter with proximal left hydroureteronephrosis with nonfunctioning left kidney. Guided fine needle aspiration cytology (FNAC) showed features of an adenocarcinoma. The patient was operated with a diagnosis of carcinoma colon and underwent low anterior resection with left nephroureterectomy. Histopathology of resected specimen revealed ureteric transitional cell carcinoma with colon infiltration. She had smooth postoperative recovery. [ABSTRACT FROM AUTHOR]

Great debate exists in the initial acute management of large bowel obstruction from obstructing left colon carcinoma. While endoscopic stenting is well established as the first approach in the setting of palliative care of patients with advanced metastatic disease as well as a bridge to elective surgery in elderly patients who have an increased risk of postoperative mortality (age >70 years and/or ASA status ≥3), controversies exist regarding oncological safety and long-term outcomes of endoscopic colonic stenting in younger patients and ESGE Guidelines do not recommend SEMS placement in patients <70 and fit for curative surgery. Particularly, the Consensus Panelists currently state that SEMS placement as a bridge to surgery is not recommended as the standard treatment because (1) it does not reduce the postoperative mortality in the general population, (2) SEMS may be associated with an increased risk of tumor recurrence, and (3) acute resection is feasible in young and fit patients, with an acceptable postoperative mortality rate. A 32-year-old lady was admitted with complete LBO from obstructing sigmoid carcinoma. Initial i.v. CE-CT scan detected a large bowel partial obstruction with fecal impaction in the entire colon until sigmoid with some mildly dilated SB loops. The presence of a thickened area in the colonic wall could not be assessed because the patient was young and thin and in such patients the CT appearance of bowel wall cannot be clearly appreciated. She was initially managed with laxatives and gastrografin. The patient's obstruction did not improve and abdominal distension worsened with nausea and colicky pain. Urgent endoscopy detected a friable mass, consistent with completely obstructing carcinoma of the mid sigmoid. Biopsies were taken and distal ink marking was made. Whole-body urgent CT scan with i.v. contrast was performed in order to obtain full preoperative staging and to rule out distant metastases. CT scan and the previously given oral gastrografin confirmed complete large bowel obstruction with a tight stricture in the sigmoid. Cecum was markedly distended. [ABSTRACT FROM AUTHOR]

A 49-year-old woman was referred to our hospital with complaints of epigastric colicky pain and high fever. Abdominal computed tomography and ultrasonography showed a solid tumor in the lower abdomen. Laparotomy revealed a neoplastic mass arising in Meckel's diverticulum; therefore, a segment of the ileum, including the tumor-possessing diverticulum, was resected with a lymph node dissection. A histologic examination confirmed the lesion to be leiomyosarcoma. In the English literature, 59 cases of leiomyosarcoma in Meckel's diverticulum were reported from 1941 to 1994. The majority of patients were in their 4th decade of life, with both sexes equally affected. The most frequent symptoms associated with this disease were abdominal pain with nausea, vomiting, and melena. The majority were larger than egg-size. Although Meckel's diverticulum is difficult to diagnose preoperatively, mesenteric arteriography may at times prove useful. The standard management of this particular tumor is wide segmental resection, including the tumor and diverticulum with lymph node dissection. [ABSTRACT FROM AUTHOR]

A case of giant gallbladder is presented. A 36-yr-old female complaining of colicky pain and a mass in the right upper quadrant underwent cholecystectomy, when the giant gallbladder, 18cm in length and 4cm in maximum diameter, and an extremely long cystic duct was confirmed. Since neither marked biliary inflammation nor biliary obstruction was observed, this giant gallbladder is considered to be congenital. [ABSTRACT FROM AUTHOR]

Infestation of the bile ducts by the adult Ascaris lumbricoides roundworm is a common condition in many parts of the world. The most frequent clinical presentation is as upper abdominal colicky pain with a normal or only slightly raised serum bilirubin. In most cases these worms can be visualized by intravenous cholangiography because of the absence of obstructive jaundice and can therefore be specifically treated by nonsurgical methods. The radiographic appearance is diagnostic. This is the first report of such a case presenting in North America or the United Kingdom, where the importance of biliary ascariasis in endemic areas is not fully appreciated.

Two patients in whom the right ureter was inadvertently catheterized at water cystometry are described. Accidental ureteral catheterization and filling was followed by colicky pain in the right flank and by an abrupt increase in the recorded pressure, up to 148 cmH2O. The pain disappeared and the intravesical pressure returned to baseline after the microtip catheter was withdrawn. [ABSTRACT FROM AUTHOR]

Patients with pancreatitis, in particular with chronic relapsing pancreatitis have recently been experienced by the authors, in which chlorophyll-a intravenously administered showed a marked therapeutic effect. Both fever and abdominal colicky pain were relieved shortly, and remarkably high levels of amylase activity in their urine returned to normal, after administration. In a series of in vitro experiments performed, it has been proved that chlorophyllin (a phytol group is removed from chlorophyll-a) exhibited an inhibitory effect on trypsin activity at the minimum concentration of 5×l0M, and 50 per cent inhibition was seen at 9×10M. On some other proteases, such as pepsin, α-chymotrypsin and kallikrein except for elastase, a more or less inhibition was also shown. Chlorophyll-a exerted, however, no effect at all, in vitro. Derivatives of chlorophyllin in which Fe, Co, Cu or Zn are chelated in place of its Mg, also showed a similar effect, while phytochlorin losing its metal from chlorophyllin, showed only a slight inhibition. From these it is most likely that chlorophyll-a is a prospective agent for treating pancreatitis, particularly chronic relapsing pancreatitis, in which even a long-term administration is to be needed, because it has no antigenicity in nature.

Because of their broad-spectrum bactericidal activity, amoxicillin (AMX) and third-generation cephalosporins (TGC) are widely used for the prophylaxis and treatment of established infections. They are considered relatively safe, but several recent reports have suggested substantial nephrotoxicity, especially with AMX use. Considering the importance of AMX and TGC for clinical practice, we conducted this up-to-date review, using the PubMed database, which focuses specifically on the nephrotoxicity of these molecules. We also briefly review the pharmacology of AMX and TGC. Nephrotoxicity of AMX may be driven by several pathophysiological mechanisms, such as a type IV hypersensitivity reaction, anaphylaxis, or intratubular and/or urinary tract drug precipitation. In this review, we focused on the two main renal adverse effects of AMX, namely acute interstitial nephritis and crystal nephropathy. We summarize the current knowledge in terms of incidence, pathogenesis, factors, clinical features, and diagnosis. The purpose of this review is also to underline the probable underestimation of AMX nephrotoxicity and to educate clinicians about the recent increased incidence and severe renal prognosis associated with crystal nephropathy. We also suggest some key elements on the management of these complications to avoid inappropriate use and to limit the risk of nephrotoxicity. While renal injury appears to be rarer with TGC, several patterns of nephrotoxicity have been reported in the literature, such as nephrolithiasis, immune-mediated hemolytic anemia, or acute interstitial nephropathy, which we detail in the second part of this review.

Rare complication of gallstone disease is gallstone ileus. The common location is the small intestine, followed by the stomach. The rarest location is colonic gallstone ileus (CGI). To summarize and define the most appropriate diagnostic methods and therapeutic options for CGI based on the paucity of published data. Literature searches of English-, German-, Spanish-, Italian-, Japanese-, Dutch- and Portuguese language articles included and Italian-language articles using PubMed, EMBASE, Web of Science, The Cochrane Library, and Google Scholar. Additional studies were identified from the references of retrieved studies. 113 cases of CGI were recorded with a male to female patient ratio of 1:2.9. The average patient age was 77.7 years (range 45–95 years). The usual location of stone impaction was the sigmoid colon (85.8%), followed by a descending colon (6.6%), transverse colon (4.7%), rectum (1.9%), and lastly, ascending colon (0.9%). Gallstones ranged from 2 to 10 cm. The duration of symptoms was variable (1 day to 2 months), with commonly reported abdominal distension, obstipation, and vomiting; 85.2% of patients had previous biliary symptoms. Diverticular disease was present in 81.8% of patients. During the last 23 years, CT scan was the most common imaging method (91.5%), confirming the ectopic gallstone in 86.7% of cases, pneumobilia in 65.3%, and cholecytocolonic fistula in 68%. The treatment option included laparotomy with cololithotomy and primary closure (24.7%), laparotomy and cololithotomy with diverting stoma (14.2%), colonic resection with anastomosis (7.9%), colonic resection with a colostomy (12.4%), laparoscopy with cololithotomy with primary closure (2.6%), laparoscopy with cololithotomy with a colostomy (0.9%), colostomy without gallstone extraction (5.3%), endoscopic mechanical lithotripsy (success rate 41.1%), extracorporeal shock wave lithotripsy (1.8%). The cholecystectomy rate was 46.7%; during the initial procedure 25%, and as a separate procedure, 21.7%; 53.3% of patients had no cholecystectomy. The survival rate was 87%. CGI is the rarest presentation of gallstone ileus, mainly in women over 70 years of age, with gallstones over 2 cm, and predominantly in the sigmoid colon. Abdominal CT is diagnostic. Nonoperative treatment, particularly in subacute presentations, should be the first-line treatment. Laparotomy with cololithotomy or colonic resection is a standard procedure with favorable outcomes. There are no robust data on whether primary or delayed cholecystectomy is mandatory as a part of CGI management. [ABSTRACT FROM AUTHOR]

Neuroblastoma is the most common solid tumor in infancy. Arising from the neural crest these tumors are usually located along the sympathetic chain from the neck to the pelvis and in the adrenal medulla. We report the case of a 3-week-old boy presenting with recurrent episodes of colicky pain. After ultrasound examination, magnetic resonance imaging and laboratory data a pancreatic neuroblastoma was suspected. Tumor resection via distal pancreatectomy and histologic investigation confirmed the diagnosis. Surgery is the treatment of choice in children with pancreatic masses, and is usually well tolerated even in the neonatal period. Conclusive diagnosis can be frequently established only by tumor resection or biopsy. Pancreatic neuroblastoma is an extremely rare tumor with only a few cases described in literature.

Background: Butylscopolamine (or hyoscine butylbromide, trade name Buscopan®) is occasionally administered as a premedication to reduce non-specific FDG uptake in the gastrointestinal tract based on its antiperistaltic effect. To date, there are no consistent recommendations for its use. The aim of this study was to quantify the reduction in intestinal and non-intestinal uptake by butylscopolamine administration and to derive relevance for clinical evaluation. Results: 458 patients (PET/CT for lung cancer) were retrospectively reviewed. 218 patients with butylscopolamine and 240 patients without butylscopolamine had comparable characteristics. While the SUVmean in the gullet/stomach and small intestine was significantly reduced with butylscopolamine, the colon and rectum/anus showed no difference. The liver and salivary glands showed a reduced SUVmean, while skeletal muscle and blood pool were unaffected. An effect of butylscopolamine was particularly evident in men and patients under 65 years of age. There was no difference in the perceived confidence in the assessment of intestinal findings in the subjective evaluation, although in the butylscopolamine group further diagnostics appeared advisable more frequently. Conclusions: Butylscopolamine reduces gastrointestinal FDG accumulation only in selected segments and, despite a significant effect, only to a small extent. A general recommendation for the use of butylscopolamine cannot be derived from these results, its use for specific issues could be considered individually. [ABSTRACT FROM AUTHOR]

Urolithiasis is the most common benign urological health condition. It has contributed sizeable burden of morbidity, disability, and medical health expenditure worldwide. There is limited high level of evidence on the efficacy and safety of treatment options of large renal stones. This network meta-analysis has examined the effectiveness and safety of various large renal stone management strategies. Systematic review and network meta-analysis (NMA) study design was employed to summarize comparative randomized controlled trials on humans with a diagnosis of renal stone larger than or equal to 2 cm in size. Our searching strategy was based on the Population, Interventions, Comparison, Outcomes, and Study (PICOS) approach. Medline via PubMed, Embase, Google scholar, SCOPUS, Science Direct, Cochrane library, Web of Science, and ClinicalTrials.gov were searched from inception to March 2023 to find eligible articles. Data extraction, screening, selection and risk of bias assessment were conducted by two independent reviewers. We found ten randomised control trials which consists 2917 patients, nine of them were labeled as low risk and one article was high risk. This network meta-analysis found that SFR was 86% (95% CI 84–88%) for Mini-PCNL, 86% (95% CI 84–88%) for standard PCNL, 79% (95% CI:73–86%) for RIRS, and 67% (95%CI:49–81 for staged URS for management of large renal stone. Overall complication rate was 32% (95% CI 27–38%) for standard PCNL, 16% (95% CI 12–21%) for Mini-PCNL, and 11% (95% CI 7–16%) for RIRS. Mini-PCNL (RR = 1.14 (95% CI 1.01–1.27) and PCNL (RR = 1.13 (95% CI 1.01–1.27)) were statistically associated with a higher SFR compared to RIRS. The pooled mean hospital stays were 1.56 days (95% CI 0.93–2.19) for RIRS, 2.96 days (95% CI 1.78–4.14) for Mini-PCNL, 3.9 days (95% CI 2.9–4.83) for standard PCNL, and 3.66 (95% CI 1.13–6.2) for staged URS. Mini-PCNL and standard PCNL were the most effective treatment options with significant morbidity and length of hospital stay, while RIRS was the safest management option with acceptable SFR, low morbidity, and short hospital stay.

Infarcts and ischemia of abdominal organs may present with acute abdominal pain, and early diagnosis is crucial to prevent morbidity and mortality. Unfortunately, some of these patients present in poor clinical conditions to the emergency department, and imaging specialists are crucial for optimal outcomes. Although the radiological diagnosis of abdominal infarcts is often straightforward, it is vital to use the appropriate imaging modalities and correct imaging techniques for their detection. Additionally, some non-infarct-related abdominal pathologies may mimic infarcts, cause diagnostic confusion, and result in delayed diagnosis or misdiagnosis. In this article, we aimed to outline the general imaging approach, present cross-sectional imaging findings of infarcts and ischemia in several abdominal organs, including but not limited to, liver, spleen, kidneys, adrenals, omentum, and intestinal segments with relevant vascular anatomy, discuss possible differential diagnoses and emphasize important clinical/radiological clues that may assist radiologists in the diagnostic process.

Purpose : The aim of this study was to investigate the actual incidence of symptomatic Petersen’s hernias (PH) as well as identify risk factors for their occurrence. Methods: Search was performed in Medline (via PubMed), Web of Science, and Cochrane library, using the keywords “Petersen Or Petersen’s AND hernia” and “Internal hernia.” Only studies of symptomatic PH were eligible. Fifty-three studies matched our criteria and were included. Risk of bias for each study was independently assessed using the checklist modification by Hoy et al. Analysis was performed using random-effects models, with subsequent subgroup analyses. Results: A total of 81,701 patients were included. Mean time interval from index operation to PH diagnosis was 17.8 months. Total small bowel obstruction (SBO) events at Petersen’s site were 737 (0.7%). SBO incidence was significantly higher in patients without defect closure (1.2% vs 0.3%, p < 0.01), but was not significantly affected by anastomosis fashion (retrocolic 0.7% vs antecolic 0.8%, p = 0.99). SBO incidence was also not significantly affected by the surgical approach (laparoscopic = 0.7% vs open = 0.1%, p = 0.18). However, retrocolic anastomosis was found to be associated with marginally, but not significantly, increased SBO rate in patients with Petersen’s space closure, compared with the antecolic anastomosis (p = 0.09). Conclusion: PH development may occur after any gastric operation with gastrojejunal anastomosis. Contrary to anastomosis fashion and surgical approach, defect closure was demonstrated to significantly reduce SBO incidence. Limitations of this study may include the high heterogeneity and the possible publication bias across the included studies. [ABSTRACT FROM AUTHOR]

The predictors of treatment outcome after emergency extracorporeal shockwave lithotripsy (SWL) are not well characterized. Therefore, based on a large prospective cohort, we aimed to develop and validate a nomogram for predicting treatment outcome after emergency SWL in patients with symptomatic ureteral stones. The development cohort included 358 patients with symptomatic ureteral stones who underwent emergency SWL between June 2020 and August 2021 in our hospital. One hundred and twenty-nine patients with symptomatic ureteral stones participated in the validation cohort from September 2021 to April 2022. The data were prospectively recorded. The backward stepwise selection was applied using the likelihood ratio test with Akaike’s information criterion as the stopping rule. The efficacy of this predictive model was assessed concerning its clinical usefulness, calibration, and discrimination. Finally, 15.6% (56/358) of patients in the development cohort and 14.0% (18/129) of those in the validation cohort suffered from stone-free failure after emergency SWL. We identified four predictors for stone-free failure: stone size, stone density, skin to stone distance (SSD), and degree of hydronephrosis. This model showed good discrimination with an area under the receiver operating characteristic (AUROC) curves of 0.935 (0.899–0.971) and good calibration (P = 0.059). The decision curve analysis showed that the model was clinically valuable. In this large prospective cohort, we found that stone size, stone density, SSD, and degree of hydronephrosis were predictors of treatment outcome after emergency SWL. This nomogram will be helpful in preoperative risk stratification to provide individualized treatment recommendations for each patient. Furthermore, early identification and appropriate management of patients may increase the success rate of emergency SWL during the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]

Hepatobiliary and pancreatic ascariasis occur due to migration of the round worm ascaris lumbricoides through the bile duct orifice finally reaching the common bile duct, main pancreatic duct, intrahepatic ducts or gallbladder. These resulted in acute epigastric and right hypochondriac region colicky pain. Ultrasound is the investigation of choice in hepatobiliary ascariasis. We present here sonographic images on four pediatric patients with acute biliary colic. [ABSTRACT FROM AUTHOR]

Inflammatory fibroid polyp of jejunum is a very rare nonneoplastic lesion of gastrointestinal tract. We reported a 66-year-old male who presented with abdominal fullness, colicky pain, and vomiting for 4 days. Plain abdomen showed intestinal obstruction with dilated small bowel loops. The exploratory laparotomy was performed under the clinical impression of intussusception caused by small bowel tumor. The diagnosis of an inflammatory fibroid polyp causing jejunojejunal intussusception was confirmed after surgery. [ABSTRACT FROM AUTHOR]

Two patients presenting with right upper abdominal colicky pain, jaundice, and fever had a hepatohiliary scan using Tc 99m HIDA. The scan was suggestive of acute cholecystitis and a space occupying lesion in the liver. On operation, liver echinococcosis, located in the right lobe rupturing into the biliary ductal system, was found. Intraoperative cholangiography revealed filling defects in the main biliary ducts. Exploration of the common bile duct disclosed daughter cysts and cystic debris. Acute cholecystitis or stones were not found. We conclude that in patients with a clinical picture and HIDA scanning compatible with acute cholecystitis and a space occupying lesion in the liver, the diagnosis of hydatid cyst of the liver which has ruptured into the biliary tract should be considered.

Background : Visceral pain (VP) following laparoscopic sleeve gastrectomy remains a substantial problem. VP is associated with autonomic symptoms, especially nausea and vomiting, and is unresponsive to traditional pain management algorithms aimed at alleviating somatic (incisional) pain. The present study was performed to evaluate the safety and effectiveness of laparoscopic paragastric autonomic neural blockade (PG-ANB) in managing the symptoms associated with VP following sleeve gastrectomy. Study Design: This prospective, double-blinded, randomized clinical trial involved patients undergoing laparoscopic sleeve gastrectomy at two high-volume institutions. The patients were randomized to laparoscopic transversus abdominis plane block with or without PG-ANB. The primary outcome was patient-reported pain scores assessed at 1, 8, and 24 h postoperatively. The secondary outcome measures were analgesic requirements, nausea, vomiting, hiccups, and hemodynamic changes immediately after PG-ANB and postoperatively. Results: In total, 145 patients (block group, n = 72; control group, n = 73) were included in the study. The heart rate and mean arterial pressure significantly decreased 10 min after PG-ANB. The visual analog scale score for pain was significantly lower in the PG-ANB than in the control group at 1 h postoperatively (p < 0.001) and 8 h postoperatively (p < 0.001). Vomiting, nausea, sialorrhea, and hiccups were significantly less prevalent in the PG-ANB group. Patients in the PG-ANB group received fewer cumulative doses of analgesics at 1 h postoperatively (p = 0.003) and 8 h postoperatively (p < 0.001). No differences between the groups were detected at 24 h (p = 0.298). No complications related to PG-ANB occurred. Conclusion: PG-ANB safely and effectively reduces early VP, associated autonomic symptoms, and analgesic requirements after laparoscopic sleeve gastrectomy. [ABSTRACT FROM AUTHOR]

Abdominal pain is a common reason for presentation in the emergency department and for calling emergency medical services. The complexity of abdominal pain also influences the analgesia strategy. However, there are almost no data on the use of ketamine for abdominal pain. This study aims to analyze the safety and efficacy of using ketamine as an analgesic for abdominal pain. In a retrospective analysis of prehospital patient data within the framework of quality assurance, all cases with ketamine administered by paramedics as analgesia for abdominal pain were analyzed in terms of pain reduction and patient safety and also compared with other analgesic drugs including fentanyl, morphine, and metamizole. From 01/01/2018 to 11/24/2021, 129 datasets were analyzed. The mean patient age was 50 ± 19 years (19–90 years), with 47.3% (n = 61) women. The application of fentanyl was documented as a monotherapy in 10.9% (n = 14), morphine in 2.3% (n = 3), metamizole in 34.1% (n = 44), and ketamine in 52.7% (n = 68) of cases. The pain relief of fentanyl, metamizole, and ketamine differed significantly from each other (p < 0.001), with fentanyl and ketamine being comparable. Looking at the quality assurance definition of successful analgesia (pain on handover NRS < 5 or pain reduction ≥ 2 points), successful analgesia was shown in 92.9% (n = 13) of cases for fentanyl, in 65.9% (n = 44) for metamizole, and 92.6% (n = 68) for ketamine (p < 0.001). Adverse events were not observed in patients treated with ketamine. Analgesia is an important goal in the treatment of patients with abdominal pain. With ketamine, analgesia comparable to fentanyl can be achieved. Ketamine appears to be a safe and effective option for the treatment of patients with abdominal pain in emergency medicine.
