perforation

Pyong Wha Choi · 2013

A 59-year-old man presented with abdominal and left flank pain. The symptom had started 30 days before as an acute nephrolithiasis, which had worsened despite conservative management. The abdomen was slightly distended and tender over the lower abdomen, without signs of generalized peritoneal irritation. A computed tomography (CT) scan showed an abscess in left para-renal space up to the subphrenic space and an unexpected pneumomediastinum. An emergency operation was performed, which showed retroperitoneal diverticulitis perforation of the sigmoid descending junction with abscess formation. A segmental resection of the diseased colon and end-colostomy was performed (Hartmann’s procedure). However, the patient’s condition progressively deteriorated, and he died of sepsis and multi-organ failure on the 5th postoperative day. Although pneumomediastinum caused by colonic diverticulitis perforation is extremely rare, it could be a life-threatening condition in patients without signs of peritonitis because of delayed diagnosis.

Perforation

Keyvan Moharamzadeh · 2018

Perforations in maxillary anterior teeth are more likely to occur at the labial aspect of the root due to the palatal inclination of the root. Perforations in multirooted teeth can occur in furcation area during access cavity preparation. Perforations have been classified based on their site into gingival sulcus, supracrestal, equicrestal, subcrestal, furcation, coronal third of the root, midroot and apical perforations. Radiographs with different angulations may confirm the presence of perforations and reveal any associated periradicular radiolucency in cases of pre-existing and pathological perforations. Cone beam computed tomography (CBCT) produces a three-dimensional image of perforation and can be extremely useful in determining the extent of pathological perforations which are often not clinically visible. The prognosis of teeth with perforation depends on a number of factors. Management options for perforated teeth include extraction, non-surgical treatment and surgical treatment.

Esophageal perforation

Ioannis S. Papanikolaou, Peter D. Siersema · 2015

Esophageal perforation, either as a complication of interventional procedures or spontaneous, is associated with significant morbidity and mortality. Besides surgical management, recent advances in gastrointestinal endoscopy and available accessories allow its management with less invasive techniques. The aim of this chapter is to provide an overview of this clinical entity and present current therapeutic options giving emphasis to endoscopic modalities. Under investigation, methods are also briefly discussed.
