Intestinal perforation secondary to intestinal Burkitt lymphoma

Emergency laparotomy for abdominal catastrophes secondary to lymphoma: A systematic review

Intestinal lymphomas can rarely present as abdominal catastrophes with perforation or small bowel obstruction. There is little data regarding their optimal surgical management and associated outcomes. We aimed to systematically review relevant published literature to assess the presentation, diagnosis, optimal surgical approach and associated post-operative outcomes. A systematic on-line literature search of Embase and Medline identified 1485 articles of which 34 relevant studies were selected, including 7 retrospective studies, 1 case series and 26 case reports. Selected articles were assessed by two reviewers to extract data. 95 patients with abdominal catastrophes secondary to lymphoma (predominately Burkitt (28 %) and Diffuse Large B-cell lymphoma (29 %)) were identified with a median age of 52 years, 40 % were female. Of the small bowel resections 25% (n = 18) suffered post-operative complications with a 13.8 % (n = 10) 30-day mortality. Ileocolonic resections had a 27 % complication rate with 18 % mortality and primary repair had a 25 % complications rate and 25 % mortality. Median follow-up was 8 days (range 1-96). Notable points of differences in the presentations between these different lymphomas included the majority of Burkitt's lymphoma were younger, had a known diagnosis, were on chemotherapy and presented with perforation in contrast to those with B cell lymphoma who were predominately older, had new diagnoses and presented with a balanced proportion of obstruction and perforation. Abdominal catastrophes secondary to intestinal lymphomas most commonly present with perforation. Aggressive surgical management, including small bowel resection, may offer similar remission rates for lymphoma patients presenting with abdominal catastrophes as those without such emergency complications.

Abdominal emergency surgery in patients with hematological malignancies: a retrospective single-center analysis

BACKGROUND

Hematologic patients requiring abdominal emergency surgery are considered to be a high-risk population based on disease- and treatment-related immunosuppression. However, the optimal surgical therapy and perioperative management of patients with abdominal emergency surgery in patients with coexisting hematological malignancies remain unclear.

METHODS

We here report a single-center retrospective analysis aimed to investigate the impact of abdominal emergency surgery due to clinically suspected gastrointestinal perforation (group A), intestinal obstruction (group B), or acute cholecystitis (group C) on mortality and morbidity of patients with coexisting hematological malignancies. All patients included in this retrospective single-center study were identified by screening for the ICD 10 diagnostic codes for gastrointestinal perforation, intestinal obstruction, and ischemia and acute cholecystitis. In addition, a keyword search was performed in the database of all pathology reports in the given time frame.

RESULTS

A total of 56 patients were included in this study. Gastrointestinal perforation and intestinal obstruction occurred in 26 and 13 patients, respectively. Of those, 21 patients received a primary gastrointestinal anastomosis, and anastomotic leakage (AL) occurred in 33.3% and resulted in an AL-related 30-day mortality rate of 80%. The only factor associated with higher rates of AL was sepsis before surgery. In patients with suspected acute cholecystitis, postoperative bleeding events requiring abdominal packing occurred in three patients and lead to overall perioperative morbidity of 17.6% and surgery-related 30-day mortality of 5.9%.

CONCLUSION

In patients with known or suspected hematologic malignancies who require emergency abdominal surgery due to gastrointestinal perforation or intestinal obstruction, a temporary or permanent stoma might be preferred to a primary intestinal anastomosis.
