Introduction Intertwining of bowel loops to form a knot is very rare cause of intestinal obstruction. Among intestinal knots, ileoileal knotting is the most rare, with only a handful of cases reported in literature. We present a rare case of ileoileal knotting and review of small bowel knots. The aim of this review was to summarise the existing evidence on small bowel knots and to postulate the possible mechanisms for knotting. Methods A systematic search was conducted for literature published up to December 2019 using MEDLINE, PubMed and Google Scholar databases, together with the references of the full-text articles retrieved. Papers with case reports of small bowel knots were considered to be eligible for inclusion in the review. Findings A total of 14 case reports were evaluated. There was no clear predilection for age or sex. Mostly cases were from Asia and Africa with no cases from the West. The presenting complaints were abdominal pain (93%), vomiting (64%), abdominal distention (57 %) and obstipation (43%). The bowel was gangrenous in 78% of cases. All underwent exploration, with the majority requiring resection and anastomosis of the involved segment. Conclusion Ileoileal knotting is a very rare cause of intestinal obstruction. Possible mechanisms include loaded bowel with longer mesentery, vigorous peristalsis, single bulky meal, pregnancy and intussusception. The condition is extremely difficult to diagnose preoperatively and it is usually diagnosed intraoperatively. The standard of treatment is resection of gangrenous part and anastomosis.
Introduction. Omental cysts are a part of cystic lymphangiomas and are benign proliferations of ectopic lymphatics without a communication with the normal lymphatic system. They commonly involve the neck in the pediatric population and are uncommon at other sites and occur rarely in adults. Case Presentation. A 42-year-old female with complaints of vague lower abdominal pain for 8 months presented with a soft, nontender swelling of size 22×18 cm in the hypogastrium and umbilical region. Computerized tomography (CT) of the abdomen showed a peripherally enhancing hypodense cystic lesion of size 19×14×12 cm perhaps arising from the mesentery. The cyst had spontaneously reduced in size by about 70% over the next 4 months. During surgery, the cyst of size 10×9×8 cm was present in the greater omentum. Excision was done, and histopathology was suggestive of cystic lymphangioma. Discussion. Cystic lymphangiomas have an incidence of 1/20000 at infancy and 1/100000 to 1/250000 of hospital admissions in adults, and the female-to-male ratio is 2 : 1. In adults, they are found in the age group between 40 and 70 years. Spontaneous regression of omental cysts is very rare and presumably from increased pressure in cysts overcoming incomplete obstructions or by establishment of alternative routes of drainage. Conclusion. As the disease is essentially benign and if there are no significant pressure symptoms, the cysts of short duration can be watched further for regression. Long-standing, symptomatic cysts, nonregression, and diagnostic uncertainty will warrant surgery to confirm the diagnosis and relieve the symptoms.
Background Gall bladder cancer (GBC) is the fifth most common malignancy in the gastrointestinal system and the most common malignancy of the biliary system. GBC is a very aggressive malignancy having a 5 year survival rate of 19%. Giant Gall Bladder (GGB) is an uncommon condition that can result from cholelithiasis or chronic cholecystitis and rarely with malignancy. Case report A 65 year old lady presented with vague abdominal pain for 12 years and right abdominal lump of size 20 × 8 cms was found on examination. CT scan showed a circumferentially irregularly thickened wall (2.5 cm) of gall bladder indicative of malignancy. Per-operatively a GB of size 24 × 9 cm was noted and patient underwent radical cholecystectomy. It was surprise to find such a giant malignant GB with preserved planes. Histopathology, it was well differentiated adenocarcinoma of gall bladder of Stage II (T2a N0 M0). Discussion It is known that mucocoele of GB can attain large size, however chronic cholecystitis will lead to a shrunken gall bladder rather than an enlarged one. A malignant GB of such size and resectable is rare without any lymph node involvement or liver infiltration. Few cases of giant benign gall bladder have been reported in literature, however this appears to be the largest resectable gall bladder carcinoma reported till date as per indexed literature. Conclusion Giant GB is an uncommon finding. They are mostly benign, however malignant cases can occur. Radiological findings may suggest features of malignancy and define extent of disease. Prognosis depends on stage of disease and resectability, irrespective of size.
A 36 year old gentleman presented with recurrent urinary tract infections, hematuria and lump in the left side of abdomen for 4 months. Clinically a soft, non-tender lump in left lumbar region with well-defined margins was palpable. CT scan of abdomen revealed a calculus of size 45 mm at the left vesico-ureteric junction with gross left hydronephrosis. Patient underwent open ureterolithotomy in view of the large size of calculus and due to stone impaction. Post-operative period was uneventful. Patient was followed up for 6 months and remained asymptomatic.
