Surgical Emergencies in the Pregnant Patient

Challenging Obstetrical Management in Generalized Peritonitis during Pregnancy

Acute abdomen in pregnancy represents a diagnostic and therapeutic challenge, despite the current advances in modern medicine, since the typical symptoms and altered laboratory parameters mimic normal pregnancy. Acute appendicitis is the most common nonobstetric surgical emergency during pregnancy, with an incidence of 1 per 500-2000 pregnancies. Delayed diagnosis and reluctance to operate on a pregnant woman predispose to adverse maternal and fetal outcomes. The elective termination of pregnancy or interventions to prolong it in the presence of appendicitis is controversial. We present a case of a 38-year-old Caucasian woman, G2P0, admitted to the Obstetric Emergency Department at 13 4/7 weeks of gestation with a primary complaint of severe nausea and vomiting associated with progressive diffuse abdominal pain which had started 7 days before. After the difficulty of inherent differential diagnosis, she was diagnosed with generalized peritonitis due to acute perforated appendicitis. Prompt exploratory laparotomy with appendectomy and drainage of multiple abscesses were performed. Conservative obstetrical management was assumed, with subsequent periodic monitoring of the fetal focus. Due to abdominal compartment syndrome, the abdomen was left open for 4 days. After 7 days in the intensive care unit, recovery was favorable, pregnancy remained uneventful, and a healthy full-term baby was born 27 weeks later. This case represents a successful example of how the cooperation of the obstetrics and general surgery teams and the decision of conservative obstetrical management in the surgical environment contributed to optimizing maternal health, achieving the best obstetrical outcome.

Role of Ultrasound in the Assessment and Differential Diagnosis of Pelvic Pain in Pregnancy

Pelvic pain (PP) is common in pregnant women and can be caused by several diseases, including obstetrics, gynaecological, gastrointestinal, genitourinary, and vascular disorders. Timely and accurate diagnosis as well as prompt treatment are crucial for the well-being of the mother and foetus. However, these are very challenging. It should be considered that the physiological changes occurring during pregnancy may confuse the diagnosis. In this setting, ultrasound (US) represents the first-line imaging technique since it is readily and widely available and does not use ionizing radiations. In some cases, US may be conclusive for the diagnosis (e.g., if it detects no foetal cardiac activity in suspected spontaneous abortion; if it shows an extrauterine gestational sac in suspected ectopic pregnancy; or if it reveals a dilated, aperistaltic, and blind-ending tubular structure arising from the cecum in suspicious of acute appendicitis). Magnetic resonance imaging (MRI), overcoming some limits of US, represents the second-line imaging technique when an US is negative or inconclusive, to detect the cause of bowel obstruction, or to characterize adnexal masses.

Clinical Outcomes of Acute Appendicitis During Pregnancy: Conservative Management and Appendectomy

PURPOSE

We have described the epidemiology, diagnostic modality, treatment patterns, and outcomes of acute appendicitis during pregnancy.

METHODS

Using a nationwide claim-based database in Japan, we analyzed the data of pregnant patients who were diagnosed with appendicitis between January 2005 and May 2019. Patient characteristics, imaging studies, length of hospital stay, proportion of fetal losses, complications, and type of antibiotics were examined.

RESULTS

The study included 169 patients, of whom 113 patients (67%) underwent conservative management, and appendectomies were performed on 56 patients (open 25% and laparoscopic 8%). The proportion of ultrasonography, computed tomography, and magnetic resonance imaging were 97%, 17%, and 5% (for conservative management); 88%, 39%, and 13% (for appendectomy); 86%, 38%, and 21% (for open appendectomy); and 93%, 43%, and 14% (for laparoscopic appendectomy), respectively. The proportion of complicated appendicitis was 6% in conservative management and 41% in appendectomy (40% in open appendectomy and 43% in laparoscopic appendectomy), respectively. The incidence of fetal loss was 4% in conservative management, 5% in appendectomy (2% in open appendectomy, and 14% in laparoscopic appendectomy). However, there was only one fetal loss (in laparoscopic appendectomy) in the same case of hospitalization. There were no maternal deaths or serious complications after any treatment.

CONCLUSION

All treatments showed acceptable outcomes in appendicitis during pregnancy. Conservative management is considered an acceptable option, especially in uncomplicated cases of appendicitis in pregnant women.

Diagnosing Appendicitis in Pregnancy Via Ultrasonography

The authors present a case of acute appendicitis during a first trimester pregnancy. Appendicitis in pregnancy is especially dangerous because perforation of the appendix increases the likelihood of maternal and fetal morbidity significantly. For this reason, it is important to diagnose and treat suspected appendicitis in pregnancy as soon as possible. The patient was diagnosed with appendicitis via a transabdominal ultrasound. She was provided antibiotics and underwent a laparoscopic appendectomy and recovered without complications.
