Background: Intestinal ascariasis is considered as state subject in our valley of Kashmir. The aim of our study was to analyse the age, clinical presentation, diagnosis, surgical complications, and management of Ascaris lumbricoides in children and adults., Methods: Total of 312 patients above 2 years of age with definite clinical and radiological diagnosis of intestinal ascariasis and associated complications were included in our study. All our patients received anthelminthic drug (Albenzadole 400 mg stat) after termination of acute phase and attached to our Out-Patient Department for follow-up. Each patient was given second dose of antihelminthic drug at second follow-up visit., Results: Total of 312 subjects included 131 (41.99%) males and 181 (58.01%) females. The highest number of patients was in age group of 6-10 years (46.47%). Colicky abdomen pain was the most common presentation and present in 80.12% patients followed by vomiting (64.1%). Palpable worm bolus was a cardinal sign present in 46.47% of our subjects. Two-hundred sixty-five (84.94%) patients responded uneventfully and were relieved of colic and obstruction after conservative non-operative treatment. Twenty (6.41%) patients underwent enterotomy and evacuation of worms, 2 (0.64%) subjects underwent resection anastomosis, and 8 (2.56%) patients had laparotomy and milking of worms into colon. None of patient expired during the study period., Conclusion: Ascaris lumbricoides is common cause of acute abdomen in our valley attributed to poor hygiene and low socioeconomic background. In patients of high clinical suspicion of worm obstruction, prompt investigations should be advised to reach a definitive diagnosis and prevent the development of complications. Significant efforts must be channelised at political and society levels for the prevention of this disease. Mass deworming programs should be adopted to overcome this menace., (© 2021.

Background: Ascariasis is the leading helminthic infection worldwide, with its peak prevalence noted in children aged 2-10 years. Although mainly asymptomatic, chronic and heavy infestation could lead to severe complications such as malnutrition, poor physical and cognitive development, as well as intestinal obstruction. We report the case of a 4-year-old boy with intestinal obstruction due to Ascaris lumbricoides infestation and discuss its public health significance., Case Presentation: A 4-year-old Black African boy from the Menchum Division in the Northwest Region of Cameroon, with no history of deworming since birth, presented with a 3-day history of generalized abdominal pains, vomiting and obstipation, and abdominal distention evolving over a period of 6 months. Clinical and paraclinical findings were in favor of a subacute intestinal occlusion associated with an electrolyte imbalance. An exploratory laparotomy was done after correction of the electrolyte imbalance. Perioperative findings revealed a dilated small bowel obstructed by bundles of live worms. An enterotomy of 2 cm in length was done, and the bundles of Ascaris lumbricoides worms extracted manually and by milking through the stoma. His postoperative period was unremarkable, and he was discharged on postoperative day 7. He and his entire household were dewormed with a single dose of mebendazole 500 mg administered orally. A follow-up visit 1 week after discharge revealed a healed abdominal wound and normal bowel functions., Conclusion: Despite considerable progress made on the control of soil-transmitted helminthiasis in Cameroon, the program faces a number of bottlenecks. Funding is inadequate, making data acquisition and hence remapping of high-risk zones difficult. Accessibility to enclaved zones where most high-risk children live is difficult, while community sensitization on soil-transmitted helminthiasis and proper education on the right environmental hygienic practices are lacking. All these challenges once addressed could go a long way to help achieve recently set sustainable development goals.

The most common cause of gallbladder perforation is calculous cholecystitis. Rarer causes include trauma, iatrogenic injuries, biliary stasis and gall bladder ischemia. We report a case of gall bladder gangrene with perforation, secondary to extensive ascariasis. A 45-year-old woman presented with acute intestinal obstruction and jaundice. She had abdominal distension and right hypochondrial tenderness. Abdominal radiography showed dilated bowel loops and ultrasonogram showed worms in the small intestine and biliary tree. On exploration, a bolus of worms 2 feet proximal to the ileocaecal junction was found causing obstruction. Worms were also present in the bile duct and gallbladder causing gangrene and perforation. She underwent cholecystectomy, bile-duct exploration and enterotomy. However, she died on the third postoperative day of overwhelming sepsis. Enteric complications of ascaris leading to bowel obstruction are well-known. Hepatobiliary complications such as cholangitis and obstructive jaundice are rare. However, such an extreme degree of infestation leading to gangrene and perforation of the gall bladder is extremely rare.

Biliary ascariasis is still the leading cause of surgical complication of ascariasis, though its incidence has been dramatically reduced. Herein, we report a case of biliary ascariasis for the purpose of enhancing awareness of parasitic infections as a possible cause. A 72-year-old male visited the emergency room of Dankook University Hospital on 12 July 2015, complaining of right-upper-quadrant pain. By endoscopic retrograde cholangiopancreatography (ERCP), a tubular filling defect in the right hepatic duct was detected. The defect was endoscopically removed and diagnosed as an adult female of Ascaris lumbricoides worm, of 30 cm length. Upon removal of the worm, the pain subsided, and the patient was discharged without any complication. When treating cases of biliary colic, physicians should not neglect biliary ascariasis as the possible cause.

Rationale: Ascariasis is an endemic parasitic disease caused by Ascaris lumbricoides, which severely burdens the healthcare system as well as harms the personal life quality, especially among less developed regions. Biliary ascariasis is a critical complication of intestinal ascariasis with painful and life-threatening manifestations. The exploration of proper strategies as its medical interventions remains largely controversial., Patient Concerns: A 16 year-old patient complained of abdominal pain and yellow sclera., Diagnoses: Biliary ascariasis INTERVENTIONS:: Laparoscopic cholecystectomy and bile duct exploration., Outcomes: More than one hundred ascarids were extracted and the patient had been discharged from hospital without any complications., Lessons: The combination of laparoscope and choledochoscope is an efficient method to treat biliary ascariasis, despite of large worm burden in the common bile duct.

Ascariasis lumbricoides is one of the most common helminthic infestations in humans. Despite the fact that the prevalence of ascariasis in developed countries has been decreasing, biliary ascariasis can cause serious complications, such as acute cholangitis, pancreatitis, and liver abscess. Here we presented a rare ascariasis-related complication-hepatolithiasis.A 60-year-old female patient had symptoms of recurrent cholangitis. Abdominal computed tomography scan revealed left intrahepatic duct stones with left liver lobe atrophy. Endoscopic retrograde cholangiopancreatography was performed, but the stones could not be removed due to left main intrahepatic duct stenosis. The patient was treated with left hemi-hepatectomy. Unexpectedly, Ascaris ova were found on the histopathological examination. She received antihelminthic therapy orally and was on regular follow-up without any complications.Our study indicates that clinicians should be aware of biliary ascariasis in patients with hepatolithiasis, though not living in endemic areas., Competing Interests: The authors have no funding and conflicts of interest to disclose.

Endoscopic retrograde cholangiography is the most commonly used technique for removal of common bile duct stones. Biliary sphincterotomy during the procedure facilitates stone retrieval from the common bile duct. However, sphincterotomy ablates the normal biliary sphincter mechanism. This facilitates duodeno-biliary reflex and can result in inward migration of luminal parasite into the biliary system. In areas where ascariasis is endemic there is an increased risk of biliary ascariasis in postbiliary sphincterotomy patients. We report an unusual case where a patient presented with recurrent biliary colic after cholecystectomy and common bile duct stone extraction and was diagnosed to have biliary ascariasis with the help of endoscopic ultrasound examination of the biliary system.

Aim: Abdominal cocoon is a rare cause of intestinal obstruction usually diagnosed incidentally at laparotomy. It manifests by forming a membrane that typically encases the small bowel loops, leading to mechanical obstruction. Preoperative diagnosis is difficult. The etiology of this condition is not well understood; however, it is a form of chronic irritation and inflammation., Method: A 33 years old male, from Bangladesh, presented to our emergency department complaining of abdominal pain, nausea, and vomiting. CT abdomen shows a picture of intestinal obstruction at the level of the small intestine. Intraoperative findings showed encapsulation of small bowel by a dense whitish membrane as a cocoon. Histological examination showed a granulomatous peritonitis and Ascaris Lumbricoides in the bowel resected., Results and Conclusions: The preoperative diagnosis of abdominal cocoon is difficult and hence, the diagnosis is usually confirmed by laparotomy. Surgery remains the cornerstone in the management of abdominal cocoon. The pathogenesis of abdominal cocoon remains elusive and has been associated with several conditions. The initial diagnosis of our patient was bowel obstruction from cocoon syndrome (CT and intraoperative findings) probably primitive, and only histologically proved granulomatous peritonitis associated with the presence of the parasite.

Background: Ascariasis is a worldwide health problem. Patients usually get treated with antihelminthics. Rarely, undiagnosed cases can present with surgical complications., Aim: To study the clinico-pathological characteristics of small bowel specimens of patients presenting with surgical complications of ascariasis., Methods: This is a retrospective analysis of small bowel specimens of patients presenting with surgical complications of ascariasis from a period of 2010 to 2012, received in our department., Results: The patients were of all age groups and mainly presented with intestinal obstruction and perforation. Transmural gangrenous change was seen in all nine cases. Encysted ova were seen in five cases. Two of the cases showed partial to complete infarction of isolated mesenteric lymph nodes., Conclusion: Ascariasis may cause transmural gangrene of bowel as well as mesenteric lymph node infarction.

Biliary ascariasis is a common problem in rural areas in China. The common presentations include biliary colic, acute cholangitis, obstructive jaundice, choledocholithiasis and acute cholecystitis. Here, we describe a case with biliary ascariasis two days after endoscopic sphincterotomy for choledocholithiasis. A living ascaris was successfully removed by endoscopic retrograde cholangiopancreatography. This case indicated that biliary ascariasis is not an uncommon complication of endoscopic sphincterotomy in some regions where ascariasis is epidemic.

Parasitic infestation is common in developing countries especially in Africa. Children are often more vulnerable to these infections. Many health problems result from these infestations, including malnutrition, iron-deficiency anemia, surgical morbidities, and even impaired cognitive function and educational achievement. Surgical intervention may be needed to treat serious complications caused by some of these parasites. Amoebic colitis and liver abscess caused by protozoan infections; intestinal obstruction, biliary infestation with cholangitis and liver abscess, and pancreatitis caused by Ascaris lumbricoides; biliary obstruction caused by Faschiola; hepatic and pulmonary hydatid cysts caused by Echinococcus granulosus and multilocularis are examples. Expenditure of medical care of affected children may cause a great burden on many African governments, which are already suffering from economic instability. The clinical presentation, investigation, and management of some parasitic infestations of surgical relevance in African children are discussed in this article., (Copyright © 2012 Elsevier Inc.

An 18-year-old man came to the Emergency Room at the Academic Hospital Paramaribo (Suriname) with a solitary supra-umbilical gunshot-wound. The patient was hypovolemic, with dropping blood pressure and rising pulse, surgery was indicated. After incision of the abdominal midline 1.5 l of blood drained, immediately followed by the appearance of 2 long thin worms. During inspection of the abdominal cavity a perforation of the duodenum and sigmoid and a mesenterial bleeding was seen and treated. Inspection of the small intestine showed presence of Ascaris lumbricoides (roundworm).

Background and Aim: Ascaris lumbricoides infection in Spain is anecdotal and is usually associated with travel to areas with high endemicity such as India and South America. Biliopancreatic disease caused by this parasite is both rare and one of the most feared complications. There are few publications in the literature about pancreatic involvement in ascariasis. We describe a case of pancreatic ascariasis diagnosed after a pancreaticoduodenectomy was performed for a suspected pancreatic adenocarcinoma., Patient: A 58-year-old man consulted for longstanding abdominal pain and diarrhea. Computed tomography and magnetic resonance scans, endoscopy, and endoscopic ultrasound-guided fine-needle cytology were performed. The pathological diagnosis was moderately differentiated adenocarcinoma of the pancreatic head., Results: Cephalic pancreaticoduodenectomy was performed. The postoperative course was favorable. A pancreatic fistula type B (ISGPF classification) developed and was resolved with conservative treatment. Analysis of the surgical specimen revealed the presence of a pancreatic pseudotumor due to Ascaris lumbricoides. After these findings, treatment was completed with oral albendazole., Conclusions: Pancreatic ascariasis in our environment is unusual, but should be included in the differential diagnosis of tumors and inflammatory processes of the pancreas., (Copyright © 2011 Elsevier España, S.L.

Chronic intussusception (CI) is defined as an intussusception lasting for 14 days or more. Because the clinical manifestations are non-specific, the diagnosis is usually delayed. Symptoms include intermittent abdominal pain, sometimes an abdominal mass is palpable and there is a marked weight loss. Diagnosis is based on typical features revealed by ultrasound or barium enema and CT investigations. Therapy is surgical with obligatory exclusion of possible underlying lesions. We report a case of a 3.5-year-old girl with chronic intussusception. Laboratory blood findings revealed sideropenic anemia and stools positive for Ascaris lumbricoides. Anti-parasitic therapy with mebendazole was repeatedly administered with early improvements but soon after symptoms relapsed. During surgery an ileocolic chronic intussusception extending to hepatic flexure was found. Postoperative control examinations proved complete healing. We suspected that Ascaris lumbricoides infestation was an etiologic factor for the development of chronic intussusception in the child.

Background/aims: Gallbladder ascariasis is rarely encountered. The causative agent is Ascaris lumbricoides. Presence of ascaris inside the gallbladder can incite acalculous cholecystitis. We aimed in this report to study gallbladder ascariasis., Methods: This is a case study of 28 patients with a diagnosis of gallbladder ascariasis from 2005 to 2010 who were seen in the Department of General Surgery, SMHS Hospital., Results: Three patients with gallbladder ascariasis had associated worms in the common bile duct. On abdominal sonography, all patients showed worms as linear echogenic shadows or the worms showed 'belly dance' of worms when actively moving. Acute acalculous cholecystitis was present in 21 patients, and 7 had biliary colic. Dead worms in the gallbladder were seen in 4 patients, of which, one was fragmented and another had calcified form of parasite. Twenty-two patients had spontaneous exit of worms from the gallbladder with a time interval ranging from 1 hour to 144 hours from the time of a diagnosis. Six patients had cholecystectomy. Two patients were subjected to emergency cholecystectomy due to multiple impacted worms not exiting from the gallbladder after conservative treatment., Conclusions: Based on our experience, ultrasound diagnosis is advocated as a highly sensitive and noninvasive technique for suspected gallbladder ascariasis and it can be repeated frequently to monitor movement of worms in the gallbladder and common bile ducts.

Ascaris Lumbricoides is the most common worm found in human beings and it is the largest of the intestinal nematodes parasitizing humanity. The most common complication of Ascariasis is mechanical bowel obstruction caused by a large number of worms. Bowel obstruction can also be caused by various toxins released by the worms. A large worm bolus can also cause volvulus or intussusception. We report a case of Intestinal Obstruction due to an Ileal MZBCL in an Ascaris. Lumbricoides infestation setting.

Ascaris lumbricoides or round worm infestation is quite common in the developing world. It affects all age groups but is more common in children. Most of the cases remain asymptomatic. The usual presentation is an intestinal obstruction. The physicians should be aware of this condition and consider it in the differential diagnosis when faced with such a case. The rare fatal complications include bleeding, perforation and gangrene.

Unlabelled: AIM/MATERIALS AND METHODS: Between January 2000 and June 2007, 3,548 endoscopic retrograde cholangiopancreatography (ERCP) were performed for extrahepatic cholestasis, cholangitis, and choledocholithiasis. The results of ERCPs were evaluated retrospectively and examined carefully to investigate the management and endoscopic therapy of biliary parasites., Results: Of the 3,548 patients who underwent ERCP, 24 (0.66%) were found to have biliary parasitosis. The mean age of the biliary parasitosis patients (16 women) was 48.6 (15-77) years. Of these 24 cases, 16 patients had hydatid cystic disease (eight with partial obstruction of the biliary tract, and eight with ruptured cysts), four patients had Fasciola hepatica, and four patients had Ascaris lumbricoides infestation. Endoscopic sphincterotomy was performed, after which the choledochus was examined carefully by balloon catheter and basket procedure., Conclusion: The ERCP procedure is very useful in the therapy of biliary parasitic infestations.

Background: The propensity of Ascaris lumbricoides to wander leads to varied surgical complications in the abdomen. Wandering A lumbricoides may sometimes reach the vermiform appendix and its presence there may remain silent or incite pathology. Our aim was to study ascariadial appendicitis., Methods: Over a period of 3 years, we identified children who were found to have appendiceal ascariasis during surgery for different intestinal complications due to ascariasis. We studied the relationship between ascariasis and its lodgement inside the vermiform appendix in these patients. No preoperative diagnosis was made in this series., Results: We found 11 patients with appendiceal ascariasis. It was incidentally found that 8/11 (72.7%) patients had worms inside their vermiform appendix but not appendicitis, whereas the remaining three patients (27.2%) were found to have Ascaris-associated appendicitis. The characteristic finding in Ascaris-infested vermiform appendix was that the worm is positioned with its head at the base and its tail at the tip of the appendix., Conclusion: Migration of A lumbrocoides inside the vermiform appendix is an incidental finding and tends to pursue a silent course in most patients. Only rarely does the presence of Ascaris inside the vermiform appendix cause appendicitis.

A 35-year-old woman presented with lower abdominal pain and amenorrhoea. CT showed a thick walled lobulated mass with Ascaris adjacent to caecum along with the presence of a left ovarian mass. The peroperative findings were a tubular mass with central tunneling containing an Ascaris lumbricoides. Left ovary showed a haemorrhagic cyst. Biopsy of the mass showed acute on chronic granulomatous inflammation and the worm was found to be female. This was a rare case of Ascaris lumbricoides presenting as a pseudotumorous mass.

Grumbach-Auvert disease represents a type of Obstructive Disease of the Intrahepatic Biliary Tree. We presents a case report of a patient with hepatic abscess caused by Ascaris which ascended into hepatic parenquima through hepaticojejunostomy, resolved by endoscopic extraction of it after the jejunostomy of permanent access was opened.

Background: Ascariasis is an endemic disease in developing countries. The parasite can invade the hepatobiliary tree and cause symptoms. Medical therapy can be ineffective in these patients and intervention techniques required., Study Design: A retrospective review of patient charts between February 1992 and February 2007 in the Hospital Latinoamericano, Cuenca, Ecuador, was performed to identify patients having surgical or endoscopic treatment for hepatobiliary ascariasis. Patient demographics, treatment algorithms, and outcomes are described and analyzed., Results: There were 13 cases of hepatobiliary infestation by ascaris treated through endoscopy or operation. All patients presented with colicky abdominal pain in the right upper quadrant. Hepatic and biliary ultrasonography identified parasites in 12 patients. In the other patient, a hepatic abscess containing ascaris was found incidentally during cholecystectomy. There were 11 patients with ascariasis in the common bile duct, 1 in whom the cystic duct was occluded, causing acute cholecystitis. In 12 patients, conservative management was attempted and was unsuccessful. Endoscopic extraction was successful in four of these patients. Six patients underwent laparoscopic cholecystectomy, common bile duct exploration with parasite extraction, and T-tube placement. Parasite extraction through common bile duct exploration followed by primary closure was performed in one patient. Cholecystotomy and parasite extraction followed by cholecystectomy were performed in one patient. The final patient had cholecystectomy and parasite extraction from a liver abscess without earlier medical therapy., Conclusions: Ascariasis in the hepatobiliary system should be considered in the differential diagnosis of upper abdominal pain for patients in populations at risk. When an operation is indicated, it can be accomplished by endoscopic or laparoscopic approach.

Adult intussusception represents 1% of patients with bowel obstructions and requires a surgical approach. Malignancy is associated with 31% of small bowel intussusception and 70% of large bowel intussusception. Intestinal intussusception caused by ascaris, however, is very uncommon. This report describes our experience of this rare cause of intussusception and its clinical findings.

Ascaris lumbricoides is a common parasite and the most serious and dramatic presentation is hepatobiliary and pancreatic ascariasis (HPA). Therefore, this study was planned prospectively to elucidate the clinical presentation of HPA and evaluate the efficacy and safety of endoscopic intervention. In this study we documented 77 consecutive patients with HPA from January 2000 to November 2005. All the patients had endoscopically proven HPA. A total of 77 patients were included in the study. The age ranged from 6 to 80 years, with the third decade most commonly (28.6%) affected. Females were 6 times more likely to be affected than males. The commonest presentation was biliary colic (97.4%); other presentations were acute cholangitis (15.6%), obstructive jaundice (9.1%), acute pancreatitis (6.5%), choledocholithiasis (6.5%), acute cholecystitis (6.5%) and liver abscess (2.6%). In this report 51 (66.2%) had living, 10 (13%) had dead and 16 (20.8%) had both living and dead worms. Choledocholithiasis was associated only with dead worms. From one to 23 worms were found in the biliary tree. In 94.8% of cases we had to remove the worm by wide papillotomy followed by basket extraction. We did not experience any major complications during or following the procedures. Three patients had recurrent HPA during the course of follow-up (1 to 12 months). The majority of patients with HPA presented with biliary colic. This should be kept in mind in the management of an acute abdomen, especially in tropical countries. Endoscopic extraction is a safe and effective procedure for the treatment of HPA.

Background: Liver abscess in childhood is a very challenging subject both for patients and doctors. In India, pyogenic liver abscesses have been found mostly in children, especially in rural areas. Liver abscess due to wandering ascarids is a common complication in children in Kashmir, although it is rare outside., Methods: The study was carried over a period of 10 years at Sheri-Kashmir Institute of Medical Sciences Srinagar India. Ten cases of liver abscesses due to wandering ascarids in children were encountered. The children were aged 2 years to 13 years., Results: 70% of the children were from rural areas. All ten patients presented with fever, while three patients presented with peritonitis. Ultrasonography was the main tool of diagnosis. All ten patients were managed by open surgical drainage., Conclusion: We conclude that Ascaris infestation should always be kept in mind while dealing with liver abscess in children.

A 35 years old lady presented with fever, biliary colic, mild jaundice, indigestion and flatulence. The upper abdominal ultrasonography revealed cholecystitis with sludge and a round worm in the common bile duct. Laparoscopic cholecystectomy and exploration of the bile duct for the removal of round worm was performed. The post-operative period was uneventful and the patient was discharged fit on the 4th post-operative day.

Roux en Y hepatojejunostomy is the surgery of choice for bile duct repair. Anastomotical dysfunction after reconstruction has several etiopathologies. Besides technical factors, ischemia of the duct is responsible for late obstruction. Bile colonization with secondary stones and sludge can also be identified as a cause. An unusual cause of anastomotical dysfunction secondary to ascaris biliary infestation after biliary reconstruction is reported herein. The patient had intermittent cholangitis and eosinophilia. At operation, the worm was found obstructing the anastomosis.

Ascariasis is the most common parasitic infestation in endemic areas and accounts for 50-60% of pediatric admissions in the surgical emergency department. Hepatobiliary and pancreatic ascariasis accounts for about 10% of such admissions. The present study was undertaken to evaluate the clinical features, investigations, and management of hepatobiliary and pancreatic ascariasis. The study was conducted in the endemic areas of Kashmir in northern India over a period of 3 years. During the study period (May 2001 to April 2004), 214 children with hepatobiliary and pancreatic ascariasis were admitted in the department. These children underwent complete clinical evaluation, investigation including ultrasound, and ERCP when required. Surgical intervention was done in patients who failed to settle with medical treatment. Ninety percent of our admissions were from rural areas and 86% of the children presented with pain in the right hypochondrium. Twenty-two percent of patients presented with cholangitis, whereas 39% of the children had mild icterus at presentation. Thirty-eight percent of the children had vomited worms during the episode of illness. Ultrasound was the diagnostic method of choice, which revealed the worms in the CBD in 80% of the patients, and in gall bladder in 16% of the children. Eight patients had worms in the main pancreatic duct while seven (4%) had multiple small liver abscesses. Serum alkaline phosphatase was raised in majority of children (80%). Twenty (9%) children were referred for ERCP. Medical treatment including endoscopic management was successful in 97% of the children. Seven (4%) children had to be operated upon due to complications of the disease. We conclude that the majority of the children with hepatobiliary and pancreatic ascariasis respond to conservative treatment, and surgical treatment is rarely needed.

We report the case of a 19-year old boy presenting in the emergency with severe epigastric pain whose biochemical tests revealed elevated serum amylase and lipase levels and a clinical diagnosis of acute pancreatitis was made. On ultrasonic examination, the pancreas appeared bulky with a linear tubular echogenic worm (ascaris) seen within the prominent main pancreatic duct. Successful removal of the pancreatic duct worm was achieved through endoscopic retrograde cholangio pancreatography (ERCP).
