1074 Gallstone Ileus: Two Decades After Cholecystectomy

Introduction Gallstone ileus is a rare complication of gallstones that occurs in 1%-4% of all cases of bowel obstruction. We present a surprising case of gallstone ileus causing small bowel obstruction 19 years after open cholecystectomy. Case Report A 77-year-old male presented with a 3-day history of abdominal pain, 4 episodes of vomiting and absolute constipation. He had a surgical background of an open cholecystectomy and open appendicectomy 19 years and 45 years ago respectively. Medically, he had well-controlled hypertension and experienced a TIA 5 years prior. Computed Tomography Scan of the abdomen and pelvis revealed features consistent with an obstructing, heterogenous opacity in the distal small bowel without pneumobilia. The patient subsequently underwent diagnostic laparoscopy. Intraoperatively, an obstructing gallstone, measuring 4 cm, was found 50cm proximal to the ileocaecal junction, with dilatation of the proximal small bowel and distal collapse. Enterotomy and removal of the stone was done. Post-operatively, this gentleman recovered without complications and was discharged home two days later after being able to tolerate a solid diet. Conclusions This is the second reported case of gallstone ileus in a patient with previous cholecystectomy about two decades ago, according to our literature search. Although extremely rare, absence of the gallbladder does not exclude the possibility of gallstone ileus.

Metastatic anorectal malignant melanoma causing ileocaecal junction obstruction due to contiguous spread

Malignant melanoma of the anal canal is a rare and aggressive tumour associated with significant mortality. Early diagnosis and early curative surgical resection have shown to offer a survival advantage. We present a case of 53-year-old woman, who was accidentally diagnosed to have a localised lesion of malignant melanoma of the anal canal on histopathology report of the specimen of haemorrhoidectomy done for thrombosed external haemorrhoids. She refused any form of treatment and did not return for follow-up. Two years after the initial diagnosis, she presented with intestinal obstruction. The malignant melanoma had become advanced with multiple metastases to the lungs, the liver, the peritoneum and the spine. The patient underwent a diverting loop ileostomy. At the time of surgery, it was found that the primary malignant melanoma of anal canal had contiguously involved the entire large intestine up to the ileocaecal junction and hence transverse colostomy could not be done.

Obstructed ileocaecal tuberculosis with splenic tuberculosis and solid pseudopapillary tumour of tail of pancreas in an immunocompetent woman

A 22-year-old young woman presented with fever, lower abdominal pain and vomiting for 20 days. She had persistent fever and abdominal pain. Fever panel was negative. Clinical features were suggestive of subacute small bowel obstruction. Contrast-enhanced CT abdomen showed thickening of distal ileum, ileocaecal junction and caecum with conglomerate necrotic nodal mass in the ileocolic mesentry along with a lesion in the tail of pancreas. Patient was discussed with multidisciplinary team and decided to undergo a single-stage procedure after adequate nutritional optimisation. During optimisation, she underwent acute obstruction and hence taken up for emergency laparotomy proceeded to right haemicolectomy with distal pancreatectomy and splenectomy 4 weeks after the time of admission. Histopathology showed ileocaecal tuberculosis and solid pseudopapillary tumour with margins free of tumour. Approach of obstructed ileocaecal tuberculosis in the setting of incidental diagnosis of solid pseudopapillary tumour of pancreas in a moribund patient was challenging.

Synchronous rectal prolapse and midgut volvulus presenting as complete small bowel gangrene

<b>Introduction:</b> Adult midgut malrotation is very rare. The presentation in adults is mostly subtle; the diagnosis is often made on imaging. <br><b>Case report:</b> A 32-year-old man presented with a 3-day history of an irreducible painful mass protruding per rectum, followed by abdominal pain and constipation. The patient was febrile and toxic, with marked signs of peritonitis and complete fullthickness irreducible rectal prolapse. Abdominal radiographs showed multiple air-fluid levels. A diagnosis of irreducible rectal prolapse with intestinal obstruction was made. Laparotomy revealed complete small bowel gangrene, abnormal rotation of the small bowel 180° around the mesenteric root, hypermobile duodenojejunal flexure and ileocaecal junction and an abnormally mobile caecum lying in the central abdomen. Abnormal mobility of the sigmoid colon with a large mesocolon, and a large irreducible rectosigmoid intussusception, was also noted. Our patient is probably the first case in literature, which may prompt awareness of simultaneously-occurring disorders of fixation, and preventive steps.

Rapunzel syndrome trichobezoar in a twelve year old girl: a case report

A bezoar refers to a mass of undigestible foreign material found in the gastrointestinal tract, mainly stomach. The second most common bezoar is the trichobezoar, which usually occurs in the young psychiatric female patients with history of trichotillomania and trichophagia. A 12-year-old female psychiatric patient came with complains of diffuse abdominal pain, vomiting, fever, and constipation. Ultrasonography and CT scan were done, which suggested trichobezoar. Thus, trichobezoar should be considered as differential diagnosis of abdominal pain in young psychiatric female patients. In the literature several treatment options are proposed, including removal by conventional laparotomy, laparoscopy and endoscopy. According to our experience and in line with the published results, conventional laparotomy is still the treatment of choice. In addition, psychiatric consultation is necessary to prevent relapses. We here report a case of 12 years old girl presented with complain of vomiting, pain and lump abdomen, loss of appetite and on laprotomy a large, approximately 156 cm trichobezoar was removed which was extending from stomach to ileocaecal junction. Trichobezoar, an underdiagnosed entity, has to be considered in the differential diagnosis of abdominal pain and a non-tender abdominal mass even in young children.

Gall stone ileus in the absence of gall bladder: a case report

Post cholecystectomy gall stone ileus is very rare with only few cases reported in the literature. This condition poses diagnostic challenges both because of its rarity and since the gall bladder had been removed previously. A high index of suspicion is needed for the diagnosis. Here, we report the case of a young female presented to the emergency room with acute intestinal obstruction. Patient underwent cholecystectomy followed by LSCS 20 yrs back. Patient was managed with explorative laparotomy which revealed an adherent, fibrosed and narrow segment of ileum containing a small impacted gall stone 120 cm from ileocaecal junction. Following the Resection anastomosis the patient made a satisfactory recovery and was discharged without any complication and is doing well.

Unusual Case of a Torted Mesenteric Fibroid

Extrauterine leiomyomas are very rare and present a clinical and diagnostic challenge due to their unusual growth patterns and behaviours. A 47-year-old woman was transferred to our tertiary specialist obstetrics and gynaecology hospital with acute abdominal pain and a palpable abdominal mass. She was taken immediately to theatre with the presumptive diagnosis of an ovarian torsion. Intraoperatively, a large necrotic mass originating from the mesentery and attachments to the bowel at the ileocaecal junction was noted. When converted to laparotomy due to limited access and poor visualisation, the uterus, ovaries, and tubes were found to be normal. A right partial hemicolectomy was performed with the assistance of the colorectal surgeon due to suspicion of bowel malignancy. Histology revealed a benign infarcted leiomyoma with adhesions to the adjacent ileum. The diagnosis of a primary torted mesenteric fibroid was made.

Biliary ascariasis presenting with gangrenous perforation of the gall bladder: report of a case and brief review of literature

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.
