Ileo-abdominal wall fistula caused by diverticulum of the ileum

Abdominal wall abscess resembling urachal carcinoma caused by ileal diverticulitis

Introduction

We report a rare case of abdominal wall abscess caused by ileal diverticulitis that developed along the midline below the umbilicus and resembled a urachal carcinoma.

Case presentation

A 76-year-old woman with diabetes presented with abdominal enlargement below the umbilicus. Computed tomography revealed a well-enhanced mass, which was visualized on magnetic resonance imaging as a continuous mass connected to the restiform structure, extending from the umbilicus to the bladder. As the mass showed high uptake on 18F-fluorodeoxyglucose positron emission tomography, urachal carcinoma was suspected, and surgery was subsequently performed. As the tumor adhered to the ileum, partial resection of the small intestine was required. The pathological diagnosis was abdominal wall abscess associated with ileal pseudodiverticulitis.

Conclusion

Although abdominal wall abscess caused by ileal diverticulitis is rare, it should be considered as a differential diagnosis of urachal carcinoma.

Incidental finding of jejunal diverticula during laparotomy for suspected adhesive small bowel obstruction: A case report

INTRODUCTION AND IMPORTANCE

Jejunal diverticula are usually asymptomatic and are discovered incidentally. While rare, their complications may be life-threatening. They should be considered as differential diagnoses in undiagnosed complaints of chronic abdominal pain, malabsorption, anemia, gastrointestinal bleed and intestinal obstruction.

CASE PRESENTATION

A 66-year lady, known hypertensive and hypothyroidism with history of hysterectomy presented with symptoms suggestive of small bowel obstruction. Intraoperatively adhesions between loops of the small intestine, multiple diverticula with two of them impending perforation were found. Resection of 10 cm of jejunum containing diverticula with end-to-end anastomosis was performed. She had uneventful recovery and on 2 months of follow-up she was doing well.

CLINICAL DISCUSSION

Although diverticula can be found anywhere along the gastrointestinal tract, jejunal diverticula are rare. Most patients are asymptomatic, symptoms if present is non-specific that delay diagnosis causing patients to land up with complications. They are diagnosed incidentally on endoscopy or imaging rather than through clinical suspicion. Asymptomatic cases do not mandate treatment while symptomatic cases can be managed conservatively with surgery being reserved for those with complications.

CONCLUSION

Small bowel obstruction due to jejunal diverticula is a rare entity, a diagnosis of which can be confirmed only intra-operatively. So it must be borne as a differential in small bowel obstruction. Timely diagnosis and management will prevent life-threatening complications of it.

Small bowel diverticulum complicated by enterocutaneous fistula and abdominal wall abscess - Case report

INTRODUCTION

Small bowel diverticular disease is uncommon, representing 1-2% of general population. The ileum diverticulum is very rare, especially if it is complicated by enterocutaneous fistula with abdominal wall abscess.

PRESENTATION OF THE CASE

Here, we report a case of small bowel diverticulum, ileum diverticulum with enterocutaneous fistula in a 65-year man presented with lower abdominal pain and an irreducible swelling for 5 days.

DISSECTION

Diverticulosis has no exact cause, but theoretically the diverticula result from peristalsis abnormalities, intestinal dyskinesia, or high segmental intraluminal pressures. Complications of small intestinal diverticulum include bleeding, diverticulitis and its complication (e.g. fistula formation, and intra-abdominal abscess) [5].

CONCLUSION

This is considered rare and serious complication of small bowel diverticulum could occur if diagnosis is delayed.

Perforated midgut diverticulitis: Revisited

AIM: To study and provide data on the evolution of medical procedures and outcomes of patients suffering from perforated midgut diverticulitis.

METHODS: Three data sources were used: the Medline and Google search engines were searched for case reports on one or more patients treated for perforated midgut diverticulitis (Meckel’s diverticulitis excluded) that were published after 1995. The inclusion criterion was sufficient individual patient data in the article. Both indexed and non-indexed journals were used. Patients treated for perforated midgut diverticulitis at Vestfold Hospital were included in this group. Data on symptoms, laboratory and radiology results, treatment modalities, surgical access, procedures, complications and outcomes were collected. The Norwegian patient registry was searched to find patients operated upon for midgut diverticulitis from 1999 to 2007. The data collected were age, sex, mode of access, surgical procedure performed and number of patients per year. Historical controls were retrieved from an article published in 1995 containing pertinent individual patient data. Statistical analysis was done with SPSS software.

RESULTS: Group I: 106 patients (48 men) were found. Mean age was 72.2 ± 13.1 years (mean ± SD). Age or sex had no impact on outcomes (P = 0.057 and P = 0.771, respectively). Preoperative assessment was plain radiography in 53.3% or computed tomography (CT) in 76.1%. Correct diagnosis was made in 77.1% with CT, 5.6% without (P = 0.001). Duration of symptoms before hospitalization was 3.6 d (range: 1-35 d), but longer duration was not associated with poor outcome (P = 0.748). Eighty-six point eight percent of patients underwent surgery, 92.4% of these through open access where 90.1% had bowel resection. Complications occurred in 19.2% of patients and 16.3% underwent reoperation. Distance from perforation to Treitz ligament was 41.7 ± 28.1 cm. At surgery, no peritonitis was found in 29.7% of patients, local peritonitis in 47.5%, and diffuse peritonitis in 22.8%. Peritonitis grade correlated with the reoperation rate (r = 0.43). Conservatively treated patients had similar hospital length of stay as operated patients (10.6 ± 8.3 d vs 10.7 ± 7.9 d, respectively). Age correlated with hospital stay (r = 0.46). No difference in outcomes for operated or nonoperated patients was found (P = 0.814). Group II: 113 patients (57 men). Mean age 67.6 ± 16.4 years (range: 21-96 years). Mean age for men was 61.3 ± 16.2 years, and 74.7 ± 12.5 years for women (P = 0.001). Number of procedures per year was 11.2 ± 0.9, and bowel resection was performed in 82.3% of patients. Group III: 47 patients (21 men). Patient age was 65.4 ± 14.4 years. Mean age for men was 61.5 ± 17.3 years and 65.3 ± 14.4 years for women. Duration of symptoms before hospitalization was 6.9 d (range: 1-180 d). No patients had a preoperative diagnosis, 97.9% of patients underwent surgery, and 78.3% had multiple diverticula. Bowel resection was performed in 67.4% of patients, and suture closure in 32.6%. Mortality was 23.4%. There was no difference in length of history or its impact on survival between Groups I and III (P = 0.241 and P = 0.198, respectively). Resection was more often performed in Group I (P = 0.01). Mortality was higher in Group III (P = 0.002).

CONCLUSION: In cases with contained perforation, conservative treatment gives satisfactory results, laparoscopy with lavage and drainage can be attempted and continued with a conservative course.

Jejunal Diverticulitis: A Rare Case of Severe Peritonitis

A 25-year-old African American female with no prior medical/surgical history presented with abdominal pain and fever. A computed tomography scan of the abdomen and pelvis showed jejunal wall thickening with an air-fluid-filled mass in the adjacent mesentery. At laparotomy, a segmental jejunal resection with the abscess cavity followed by primary anastomosis was performed. Pathological evaluation of the specimen revealed a large mesenteric abscess contiguous with a perforated solitary jejunal diverticulum. We provide a discussion of jejunal diverticulitis as an unusual cause of peritonitis.

Abdominal wall abscess associated with perforated jejunal diverticulitis: report of a case

We report a case of abdominal wall abscess caused by diverticulitis of the jejunum penetrating through the abdominal wall. A 53-year-old Japanese woman visited a local hospital complaining of abdominal pain and a mass in the left lower abdomen. An abdominal computed tomography scan showed a tumor with isodensity in the left lower abdominal wall. Magnetic resonance imaging showed a mass in the abdominal wall with isointensity in the T1-intensified image and high intensity in the T2-intensified images. The mass was heterogeneous inside and protruded partially toward the intraperitoneal cavity. Ultrasound examination showed a heteroechoic mass extending into the intraperitoneal cavity. Laparotomy revealed a tumor in the abdominal wall with a fistulous tract extending to the jejunum. We resected the abdominal wall tumor with partial resection of the small intestine. The resected specimen contained a tumor with a fistulous tract passing through the abdominal wall. Histological examination revealed remarkable infiltration of neutrophils and a bacterial mass in the abdominal wall tumor, with a fistulous tract connected to the area adjacent to the mesenteric border of the jejunum. These findings suggested that diverticulitis of the jejunum had penetrated through the abdominal wall, leading to the formation of an abscess. We report this case to highlight the need for complete gastrointestinal evaluation with gastrointestinal barium studies and imaging analysis to examine extension of intra-abdominal lesions in patients with an unexplained abdominal wall abscess.
