Solitary cecal diverticulitis is a rare cause of abdominal pain in Western countries. The preoperative diagnosis is very difficult to establish and most patients are operated on with a presumptive diagnosis of acute appendicitis based on clinical grounds. We describe a very rare case of perforated posterior cecal diverticulum and discuss the challenges in establishing a correct preoperative diagnosis. We conclude that although very rare, the possibility of perforated posteriorcecal diverticulum should always be considered in the differential diagnosis of patients presenting with atypical clinical manifestations of acute appendicitis. A perforation of a posterior cecal diverticulum maybe associated with a mild clinical course without signs of peritonitis. Athorough preoperative evaluation including a computed tomography scan is essential in order to establish a correct preoperative diagnosis which is of utmost importance for treatment planning in the emergency setting. Simple diverticulectomy is an effective surgical treatment in the absence of extensive inflammatory changes and when a colonic tumor can be ruled out.

Acute appendicitis is a common surgical diagnosis but several differential diagnoses exist and should be considered. Internal concealment is one such diagnosis. We present a case of a young man taken to the operating room with a preoperative diagnosis of complicated acute appendicitis. A ruptured caecum was encountered and several free-floating drug pellets were present. Attending doctors should consider this differential in the high prevalence areas and, whenever encountered, they should strongly consider early reporting., (© The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

Aim: To describe three cases of solitary cecal diverticulum, and trying to evaluate the better method of diagnosis and treatment with analysis of the literature., Material of Study: Description of three cases of solitary cecal diverticulum's perforation admitted in the Department of General and Oncologic Surgery, Santa Maria della Misericordia Hospital, Perugia, during the period January 2011 - January 2012., Results: In all patients the clinical presentation was very similar to that of acute appendicitis. Preoperative diagnosis was achieved in one case through abdominal CT scan, other two cases were identified at final pathology. At one year from the treatment all patient are still alive., Discussion: Cecal diverticulum is a rare condition, often diagnosed either casually or because of inflammatory or perforative complications. The highest incidence is found in Western population. Because of the clinical presentation, very similar to the appendicitis, and the inflammatory reaction involving the colon and its surrounding tissues, the pre- and intra-operative diagnosis are very difficult. The diagnosis is almost always histological. The treatment may vary from simple expectant medical management, carried out with bowel rest, parenteral support and antibiotics as for left-sided diverticulitis, to surgical approach, performed through simple diverticulectomy or by classical right hemicolectomy., Conclusion: Pre-surgical and, also intra-operative, diagnosis of perforated solitary cecal diverticulum is clearly difficult. CT scan represents the gold standard for the differential diagnosis. Right hemicolectomy is an effective and safe approach, allowing accurate control, preventing complications and recurrences, and it represents the optimal management of the disease.

Chilaiditi sign is a radiological finding which describes the interposition of a part of the bowel between the diaphragm and the liver, a finding that can be misinterpreted as pneumoperitonium. Chilaiditi syndrome refers to a clinically symptomatic patient in the presence of the classical radiographic findings. It is a very rare syndrome which usually follows a benign course. Here we report the first documented case of Chiliaditi syndrome complicated by cecal perforation.

Behcet's disease (BD) has been recognized as multi-systemic chronic vasculitic disorder of recurrent inflammation, characterized by the involvement of multiple organs and resulting in orogenital ulcers, uveitis, and skin lesions. Involvement of the central nervous system, vessels, and intestines in BD often leads to a poor prognosis. Digestive manifestations in BD have been reported in up to 1-60% of cases, although the rate varies in different countries. The most frequent extra-oral sites of gastrointestinal involvement are the ileocecal region and the colon. Gastric or esophageal involvement is reported to be very rare. Moreover, there have been no reports on the simultaneous involvement of the esophagus, stomach, ileum, and colon. Here, we present a 55-year-old Korean man with intestinal BD and multiple ileal and colonic ulcerations complicated by perforation, gastric ulcer with bleeding followed by perforation, and esophageal ulcers with bleeding.

Acute right lower abdominal pain is often clinically difficult to diagnose. The diagnosis, especially in young patients, is frequently oriented to appendicular disease. Surgical exploration only confirms diagnosis or surprises the surgeon, revealing an unexpected right colon diverticulitis. This emergency condition challenges the surgeon with the dilemma about the best therapeutic choice: conservative or radical treatment? The elective localization of diverticulitis to the right colon is very rare (6.6-14%). The authors report a case of covered perforation of a solitary cecal diverticulum.

A patient was treated for hydronephrosis caused by an intra-abdominal abscess arising from cecal perforation by an ingested fish bone. To the authors' knowledge there is no previous report of such ureteral obstruction. Ureteral stenting, drainage of the abscess, and ileocecal resection were performed. Six months of stenting were required to attain ongoing ureteral patency following removal.

Synchronous colonic events are rare. Diverticulitis is the most common and lethal cause of colonic perforation. The first case in the literature of a synchronous diverticular perforation is presented. The patient was admitted with peritonitis. An exploratory laparotomy showed cecal and sigmoid perforations. Resection and primary anastomosis with a protective loop ileostomy was performed. Microscopic evaluation confirmed the presence of cecal and sigmoid perforated diverticuli. Diverticular disease is present in up to two-thirds of patients 80 years of age and older. Right-sided free colonic perforation is rare. Resection and primary anastomosis is feasible in the treatment of perforated diverticular disease. In this report, we emphasize the importance of a thorough abdominal exploration at the time of surgery.

Cecal volvulus is an uncommon cause of large-bowel obstruction. Its developement is due to an abnormal mobility of the ileocecal loop because of lacking attachement of ascending colon. Clinical features are frequently aspecific and should be differentiated from sigmoid volvulus and neoplastic obstruction. Therapy depends on visceral circulatory conditions at the moment of diagnosis. Possible options include endoscopic decompression, cecopexy with or without cecostomy, right colectomy with immediate or delayed anastomosis. The present paper reports the case of cecal volvulus in a 44 year old woman, successfully treated with right colectomy and primary anastomosis.

The Authors report a case of acute abdomen caused by a perforated solitary diverticulum of the cecum recently treated. This is a rare disease that usually is diagnosed, in the surgical theatre because it is a topic of emergency surgery. From Literature analysis it is obvious that a correct preoperative diagnosis is difficult to make because of the large number of possible abdominal pathologies with similar symptoms. Also the therapeutic approach is so extremely variable that the operation could range from a simple conservative type to right hemicolectomy. A proper approach will be conservative with a simple diverticulectomy when the inflammatory reaction is localized in the colonic wall while a right colectomy could be performed when the inflammatory reaction is more advanced or a large mass suggestive of a carcinoma is present.

A case of an absent diseased appendix in an incompletely rotated gut in a 35-year-old farmer along with its management and review of literature is presented here.

Primary intestinal tuberculosis is unusual in European and North American countries today. Its diagnosis is often surprising and differentiation from inflammatory bowel diseases is difficult. The authors present a rare case of severe stercoral peritonitis caused by multiple intestinal perforations in a patient with primary ileocecal tuberculosis. Initial clinical and laboratory investigations led to the suspicion of inflammatory bowel disease. The subsequent diagnostic workup included colonoscopic examination of the cecal and terminal region of the ileum with multiple biopsies. After the pathologist had assessed the specimen as indicating Crohn's disease, appropriate therapy was initiated. Several days later, however, the patient was readmitted to a surgical intensive care unit with clinical signs of peritonitis and immediately operated on. The final diagnosis from a resection specimen confirmed the diagnosis of primary intestinal tuberculosis. The follow-up was complicated by a subhepatic abscess formation with the necessity for surgical drainage. The patient's recovery was uneventful, she underwent intensive antituberculotic therapy and is asymptomatic at present. Surgeons caring for patients with acute abdomen should be aware of tuberculous perforation peritonitis even in non-risk groups of patients., (Copyright 2001 S. Karger AG, Basel)

A 34-year-old woman, was admitted to the emergency room of our hospital with a history of symptoms of abdominal pain dating back several years and transitorily related to the menstrual cycle. These had worsened in the days prior to admission. Radiological and clinical examinations detected no signs of peritonitis. During exploratory operative laparoscopy, opted for because of persistence and intensification of the abdominal pain, diffuse peritonitis was found due to an ileal perforation immediately upstream of an ileocaecal mass causing a precaecal stenosis. Laparoscopy enabled us to diagnose the preoperatively undetected complication, to perform a through peritoneal lavage and, following minimal conversion by laparotomy, to perform ileocaecal resection, thereby limiting the severity of the surgical trauma. The definitive pathological diagnosis was ileocaecal endometriosis with signs of transmural fistulisation and the presence of endometrial glandular structures in one of the lymph nodes around the lesion. Perforation is a rare complication on those segments of the intestine most often affected by endometriosis, such as the colon and appendix. However, it is even more unusual when it affects the ileum and no other cases have been reported in the literature. Its genesis is attributed to late diagnosis. The pathological findings highlight the particular characteristics of this case. We would stress the pre-, intra- and postoperative diagnostic difficulties encountered and the importance of a thorough anamnestic assessment when making differential diagnoses in women of child-bearing age with abdominal or pelvic pain and perimenstrual symptoms.

The aetiology of perforation of large bowel diverticula is poorly understood and a case-control study is required to identify the causes. Before such a study can be attempted, the incidence must be determined and groups at particular risk identified. Cases of perforated large bowel diverticula living in the Norwich postal code region treated between 1995 and 1997 were identified. Fifty-eight cases presented in a population of 531 241. The incidence was 4.0 cases per 100,000 per year, increased with age and was higher in men than women (5.8 vs 3.1). The most frequently used drugs were non-steroidal anti-inflammatory drugs (NSAIDs) (29%) and opiate analgesics (26% of cases). This is the first report of the incidence of perforated diverticular disease and allows a calculation of the population size needed to recruit sufficient cases for an aetiological investigation. The differences in incidence between genders should prompt a search for factors which differ between the sexes such as diet. NSAIDs are a known risk factor, although the data show that opiate analgesics should be investigated.

A rare case of peritonitis by cecal perforated diverticulum which was diagnosed after surgery by histology is reported. Preoperative diagnosis is often ignored and, in rare cases, is not always clear at laparotomy. Clinical aspects, diagnostic procedures, histological picture and surgical treatment are described. In the literature diverticula are classified as "solitary" and "multiple", "congenital" and "acquired", "true" and "false" and finally "usual type" and "hidden variant". The treatment of cecal acute diverticulitis is, in the majority of patients, surgery. Simple resection of the diverticulum and suture of the breach in double layer is the elective operation of non-complicated diverticulum or with an inflamed projection from the cecal wall ("usual type"). Segmental resection of colon or "right hemicolectomy" is recommended when a precise diagnosis is not possible and in complicated diverticula ("hidden variant"). On the basis of personal experience it is underlined that diagnosis is rarely made preoperatively since the clinical picture suggests an acute appendicitis. If there are some doubts for appendicitis, a incidental tumor or possible perforated diverticulum of the cecum should be considered and urgent surgery is mandatory.

Acute colonic pseudo-obstruction (Ogilvie's syndrome) is characterized by physical examination and radiologic findings indicative of mechanical obstruction but in which no physical obstructive process can be found. Many factors have been associated with this syndrome which include electrolyte imbalance, systemic infection, drugs, and occasionally, neurologic disease. Reported here is a case of acute colonic pseudo-obstruction which developed in a patient with known Parkinson's disease and was complicated by cecal perforation, yet had a favorable outcome.

Two cases of perforations in diverticulitis of the caecum are presented. The disease was manifested with the following complications: inflammation and perforation. Diverticula of the caecum are asymptomatic, accidentally found during surgery undertaken for other reasons. Out two patients were admitted to the hospital as emergency-patients, with the suspicion of acute appendicitis. Symptoms were unusual. Both patients were operated on. Histopathologic findings confirmed the diagnosis of acute perforated diverticulitis of the caecum in both cases.

Objective: To study the therapeutic effect of granulocyte colony-stimulating factor (G-CSF) on the mortality rate and host defense pattern in fulminant intra-abdominal sepsis., Design: Prospective, randomized, controlled trial., Setting: Research laboratory in a university hospital., Subjects: Adult male Wistar rats., Interventions: Fulminant polymicrobial intra-abdominal sepsis was induced by a 4-mm cecal perforation. Survival experiments were performed with two different doses of G-CSF (20 and 100 microg/kg/24 hrs), and therapy was started 7 days or 1 day before, or 4 hrs after sepsis induction (n = 24). To examine alterations in host response pattern, G-CSF (20 microg/kg/24 hrs) was given at sepsis induction, and rats were killed 4, 8, 12 and 24 hrs later (n = 8-16 per time period). Histologic examination of lung, liver, spleen, and kidney was performed, and blood concentrations of bacteria, endotoxin, tumor necrosis factor (TNF), endothelin-1, packed cell volume, and lactate were determined., Measurements and Main Results: G-CSF (20 microg/kg/24 hrs), given 4 hrs after sepsis induction, reduced the mortality rate from 96% to 42%. Increasing the dose (100 micrograms/kg/24 hrs), or giving G-CSF as prophylaxis (starting 7 days or 1 day before sepsis), gave no further protection. G-CSF attenuated the sepsis-induced enhancement of circulating bacteria, endotoxin, TNF, and endothelin-1, resulting in improved fluid balance and reduced lactate concentration. No histopathologic alterations were observed after G-CSF treatment., Conclusions: G-CSF improves host defense and survival rate in experimentally induced fulminant intra-abdominal sepsis. Clearance of bacteria and endotoxin is improved, concentrations of TNF and endothelin-1 are suppressed, and microvascular flow is improved. G-CSF does not induce neutrophil-mediated tissue damage.

A ten year old boy who died of the consequences of an infrequent gastrointestinal complication, whilst on induction chemotherapy for acute lymphatic leukemia, is being reported. Recent trends in the diagnosis and management of typhilitis or neutropenic enterocolitis have been reviewed.

Acute mesenteric vein thrombosis is a rare complication of appendicitis. In this report we describe the clinical association of these entities and emphasize how early diagnosis by CT can expedite treatment.

The Authors, after a brief review of the literature on the frequency and localization of large bowel diverticular disease report a case of perforation of a cecal diverticulum operated on emergency. They also add some brief comments on the interesting aspects of the case, its diagnostic difficulties and operating technique.

This work uses cecal perforation on the rat as a model of intra-abdominal sepsis. Under these conditions, various antibiotics were tested alone or in association with free radical scavengers, such as allopurinol and catalase. It can be concluded that the scavengers were not effective alone, but when combined with antibiotics they rendered good results in the majority of the groups when given postsepsis. Further studies are needed to determine the real role of agents like the free radical scavengers in infectious situations such as the one discussed here.

A 73-year-old man with chronic renal failure of undetermined aetiology had received haemodialysis for 12 years when he died of acute purulent peritonitis due to caecal perforation. Amyloid deposits detected in a cystic bone lesion in the left hip had caused a pathological fracture 17 days before death. At autopsy, extensive amyloid deposits were found in the osteoarticular system, in the cartilaginous surface and the capsular tissue of joints, ligaments, vertebral discs and bone. In addition, vascular amyloid deposits were diagnosed in the heart, kidneys, testes, lungs, skin and in the gastrointestinal tract. A special feature of this case were interstitial amyloid deposits forming a fine-meshed structure in the myocardium and plate-like deposits in the gastrointestinal tract. Immunohistochemically, all these deposits reacted strongly with antibody to human beta 2-microglobulin but showed no reaction with antibodies to AA, A-lambda, A-kappa and AF. The present case demonstrates that extra-osteoarticular manifestations of AB-amyloidosis can cause serious complications.

Perforation of a solitary cecal diverticulum is a rare cause of acute abdomen and an uncommon differential diagnosis for acute appendicitis. Nine hundred cases have been described since Potiers first description in 1912, either localized in the cecum or in the ascending colon. A further case and its course are described.

This study was done to determine the association between appendiceal fecaliths or appendiceal calculi and the presence of acute appendicitis. We retrospectively reviewed the medical records of all patients from 1977 through 1986 who underwent appendectomy for a clinical diagnosis of acute appendicitis (group 1, 2,331 patients) or who underwent appendectomy either incidentally or during colectomy for nonappendiceal pathologic factors (group 2, 1,066 patients). Fecaliths were six times more common than calculi, but calculi were more often associated with perforated appendicitis or periappendiceal abscess (45 per cent) than were fecaliths (19 per cent). Appendiceal fecaliths and calculi appear to play a role in the pathogenesis of acute appendicitis and are associated with complicated appendicitis (perforation and abscess). Appendectomy should be considered for patients in whom an appendiceal calculus is recognized incidentally.

Cecal diverticulitis is a relatively rare disease, which closely mimics the picture of acute appendicitis. At times it is difficult to differentiate from carcinoma. Five cases of cecal diverticulitis are reported, with a discussion of some salient features of this condition. Although two cases were treated with a right hemicolectomy, a plea for conservatism in the treatment of this disease is made.

Gastrointestinal perforation into the retroperitoneum may present as thigh emphysema. In the elderly, abdominal symptoms may be minimal. We report a patient with a perforated cecal carcinoma presenting as right hip pain with thigh emphysema. A diagnosis of perforated intra-abdominal viscus was suspected from the radiographs. The patient initially did well after surgery, which included a hemicolectomy and debridement of necrotic muscle down to the knee. He later succumbed from cardiac arrest following a dyspneic episode.

The authors report the occurrence of fatal embolism as a complication of a LeVeen peritoneovenous shunt performed four months previously in a 67-year old man with ascites. Air embolism was caused by perforation of the cecum following cauterization of a vascular malformation of the mucosa through a flexible colonoscope. An autopsy demonstrated air within the peritoneal cavity, the LeVeen shunt and both ventricles of the heart. In the patient with a LeVeen shunt, gastrointestinal perforation from any cause is an indication for immediate closure of the shunt.

Segmental dilatation of the colon without obstruction is an unusual but recognizable entity, distinct from mechanical obstruction and paralytic ileus. Cases of ileus of the colon with cecal dilatation following delivery and gynecologic surgery are collected from the literature, and 3 recent cases are presented: 1 following cesarean section and 2 following abdominal hysterectomy. The etiology of this condition is still obscure and the clinical features are deceptive. The occurrence of this entity in obstetric and gynecologic patients is by no means a rarity and warrants a familiarity with and early recognition of this entity on the part of the physician in order to avoid serious sequelae.

The literature on simple ulcer of the colon is reviewed. Three successfully treated cases of spontaneous perforation of the colon due to ulcer of the sigmoid, and single and multiple ulceration of the caecum are described, with particular reference to their aetiopathogenesis. The view that simple ulcer is caused by mechanical and circulatory factors, with or without inflammation, is expressed. Surgical management of this lesion must take the patient's age and local and general condition into account. These parameters will determine the type of operation employed, ranging from simple colorrhaphy to variously extensive resection of the perforated segment.

A case of solitary cecal ulcer with major hemorrhage followed by perforation after treatment with intra-arterial vasopressin in a patient with end-stage renal failure is presented. Though vasopressin has been used with success in the treatment of colonic hemorrhage, caution should be applied in patients with a bleeding cecal ulcer as the vasoconstriction produced by vasopressin may cause perforation in an area whose blood supply is already compromised.
