Fecal impaction (FI) is a common and potentially serious medical condition that occurs in all age groups. Children, incapacitated patients, and the institutionalized elderly are considered the highest at-risk populations. FI usually occurs in the setting of chronic or severe constipation, anatomic anorectal abnormalities, and neurogenic or functional gastrointestinal disorders. Generally, FI is a preventable disorder, and early recognition is important, as it is associated with increased morbidity, mortality, and high health care costs. Evaluation with a careful history and physical examination, in conjunction with radiologic imaging, such as an acute abdominal series or computed tomography (CT), is imperative. Prompt identification and treatment minimize the risk of complications attributable to FI, which may include bowel obstruction leading to stercoral ulcer, perforation, peritonitis, or cardiopulmonary collapse with hemodynamic instability. Treatment options include manual fragmentation and extraction of the fecal mass, distal colonic cleansing using enemas and rectal lavage with the aid of a sigmoidoscope, and/or using water-soluble contrast media such as Gastrografin to both identify the extent of the impaction and aid in cleansing and removal. Surgical resection of the involved colon or rectum is reserved for peritonitis resulting from bowel perforation. Since recurrence is common, implementing preventive measures such as increasing daily water and fiber intake, limiting medications that decrease colonic motility, using secretagogues or prokinetic agents, and treating underlying anatomic defects are highly important.

Small bowel obstruction due to undigested fibre from fruits and vegetables is a rare but known medical condition. We report a case of small bowel obstruction caused by a whole cherry tomato in a patient without a past medical history of abdominal surgery. A 66-year-old man presented to the emergency department complaining of lower abdominal pain with nausea and vomiting. His last bowel movement had occurred on the morning of presentation. He underwent abdominal computed tomography (CT), which showed a sudden change of diameter in the distal ileum with complete collapse of the proximal small bowel segment. Laparoscopy confirmed a small bowel obstruction with a transition point close to the ileocaecal valve. An enterotomy was performed and a completely undigested cherry tomato was retrieved. To our knowledge, this is the first reported case of a small bowel obstruction caused by a whole cherry tomato.

A 32 year old woman presented with acute onset of abdominal pain and fever. An urgent computerised tomography (CT) of the whole abdomen showed dilated loop at the terminal ileum in the right lower abdomen with thickening of the wall and oedema. The CT was suggestive of distal small bowel obstruction at the ileum with surrounding wall oedema. Multiple biopsies taken from the terminal ileum and colon on colonoscopy were all unremarkable. She represented one-year later with a recurrence of intestinal obstruction. CT enteroclysis showed collapse at the distal 3 cm segment of the terminal ileum. There was no associated wall thickening, active inflammatory changes or ileitis. This was suspicious of post-inflammatory change or fibrosis. She was subsequently found to have selective IgA deficiency with recurrent infection in the terminal ileum resulting in intestinal obstruction. In conclusion, selective IgA deficiency should be considered in patients with recurrent intestinal obstruction without anatomical obstructions.

We report a unique case of a 79-year-old woman with metastatic rectal cancer who developed bowel obstruction following endoscopic cryotherapy with liquid nitrogen for palliation of bleeding in the rectum. She developed abdominal distention and pain following the procedure. Computed tomography of the abdomen revealed a paraumbilical hernia containing a segment of transverse colon resulting in partial bowel obstruction. It appears that the recurrent freeze-thaw cycles with poor decompression of the colon despite active venting suction during cryotherapy may have resulted in bowel distention and collapse, causing conformational changes resulting in partial bowel obstruction due to a paraumbilical hernia.

A 35-years-old female post-endoscopic gastroplasty presented to the emergency department complaining of epigastric abdominal pain. The abdominal examination showed epigastric and tenderness. On abdomen computerized axial tomography (CAT) scan she had small bowel obstruction with twisting of mesenteric vessel. The patient taken to the operating room for diagnostic laparoscopy and proceed, laparoscopic examination showed proximal dilatation of small intestine with collapse of distal part of jejunum, the obstruction identified, as fibrous band originating from the stomach to the proximal part of jejunum, this band caused by suture penetrating the stomach wall, which is going with the previous history of the endoscopic gastroplasty, reduction of the internal hernia done by releasing of the fibrous band, the herniated segment was healthy. Internal hernia can present with variety of complications. To the best of our knowledge from the literature review, this is the first case to be reported as internal abdominal hernia secondary to endoscopic gastroplasty.

A 38-year-old woman who had been previously diagnosed with irritable bowel syndrome was seen in the outpatient clinic with a 2-year history of intermittent cramp-like abdominal pain which was often followed by watery diarrhoea. She had presented several times previously to the emergency department with episodes of severe pain and collapse although on arrival examination findings were mostly unremarkable other than some mild lower abdominal tenderness. On each occasion, the symptoms resolved spontaneously with conservative management. She had been extensively investigated by her general practitioner to establish the cause of her symptoms but all laboratory findings, cross-sectional imaging, ultrasound and oesophagogastroduodenoscopy to date were unremarkable. After being seen in gastroenterology outpatients' clinic, a colonoscopy was performed and was described as being macroscopically normal but microscopic evaluation of colonic biopsies suggested a possible 'resolving infection'. She was treated symptomatically, but within 6 months she represented to hospital with progressively worsening symptoms of severe abdominal pain, now associated with vomiting, followed by watery diarrhoea and then resolution of the symptoms. An abdominal CT scan was performed which showed a small intraluminal-filling defect in the mid-terminal ileum. A wireless capsule endoscopy was organised to further characterise the lesion although this was reported as showing no abnormality. Prior to any further outpatient investigations, she represented as an emergency to hospital in small bowel obstruction, underwent further cross-sectional imaging followed by surgical resection of the lesion. Histological characterisation revealed a small bowel inflammatory fibroid polyp.
