Natural History of Pneumoperitoneum After Laparotomy: Findings on Multidetector-Row Computed Tomography

Peptic ulcer perforation after cesarean section; case series and literature review

BACKGROUND

Peptic ulcer perforation in the early post-cesarean period is rare but may result in maternal mortality.

CASE PRESENTATION

Four cases of post-cesarean peptic ulcer perforation are presented. In all four patients, presentations include peritoneal signs such as acute abdominal pain and progressive distention, hemodynamic instability and intraperitoneal free fluid by ultrasound. Laparotomy and repair were done in all 4 cases. There were 2 maternal deaths. We also have reviewed English literature for the similar cases reported from 1940 to March 2019.

CONCLUSION

New onset tachycardia, abdominal pain and progressive distension after cesarean section without congruent changes in hemoglobin should raise concerns for intra-abdominal emergencies including perforated peptic ulcer. Early use of ultrasound should be considered to assist in diagnosis. Coordinated care by an obstetrician and a general surgeon is necessary in presence of any unusual postoperative abdominal pain. Early recognition of the disease is imperative to limit the surgical delay and to improve the outcomes.

Early postoperative imaging after non-bariatric gastric resection: a primer for radiologists

Abstract

Surgical resection represents the mainstay treatment and only potentially curative option for gastric carcinoma, and is increasingly performed laparoscopically. Furthermore, other tumours and selected cases of non-malignant disorders of the stomach may require partial or total gastrectomy. Often performed in elderly patients, gastric resection remains a challenging procedure, with significant morbidity (14–43% complication rate) and non-negligible postoperative mortality (approximately 3%). This paper provides an overview of contemporary surgical techniques for non-bariatric gastric resection, reviews and illustrates the expected postoperative imaging appearances, common and unusual complications after partial and total gastrectomy. Albeit cumbersome or unfeasible in severely ill or uncooperative patients, contrast fluoroscopy remains useful to rapidly check for anastomotic patency and integrity. Currently, emphasis is placed on multidetector CT, which comprehensively visualizes the surgically altered anatomy and consistently detects complications such as anastomotic leaks and fistulas, duodenal stump leakage, afferent loop syndrome, haemorrhages, pancreatic fistulas and porto-mesenteric venous thrombosis. Our aim is to help radiologists become familiar with early postoperative imaging, in order to understand the surgically altered anatomy and to differentiate between expected imaging appearances and abnormal changes heralding iatrogenic complications, thus providing a consistent basis for correct choice between conservative, interventional or surgical treatment.

Teaching points

• Radical gastrectomy is associated with frequent postoperative morbidity and non-negligible mortality.

• In cooperative patients fluoroscopy allows checking for anastomotic patency and leaks.

• Multidetector CT with / without oral contrast comprehensively visualizes the operated abdomen.

• Awareness of surgically altered anatomy and expected postoperative appearances is warranted.

• Main complications include anastomotic and duodenal leaks, haemorrhages and pancreatic fistulas.
