Intestinal obstruction in pregnancy: a case report

Midgut Volvulus in Disguise: Acute Abdomen in Early Pregnancy

Small bowel obstruction (SBO) in pregnancy is a challenging diagnosis. Case rarity, non-specific presentations, and the non-practicality of using X-ray/gamma-ray imaging modalities in pregnancy contribute to the increased difficulty in timely diagnosing midgut volvulus during pregnancy, thereby increasing maternal and fetal morbidity. We report a case of midgut volvulus in a 39-year-old lady, gravida 3, para 2, with two previous cesarean sections. Her only presenting complaint was abdominal pain for three days with no other associated symptoms. The case was successfully diagnosed using magnetic resonance imaging (MRI) and subsequently treated surgically by segmental resection with side-to-side ileocecal anastomosis, thereby saving the mother and fetus. Clinicians should have a low threshold of suspicion of the varied causes of SBO in pregnancy, particularly in patients with prior abdominopelvic surgeries. Imaging is central to preoperative diagnosis, and MRI has gained popularity with safety and accuracy comparable to computed tomography. Management aims at minimizing maternal and fetal morbidity and mortality.

A Case of a Patient with Adhesive Small Bowel Obstruction in Pregnancy after Extensive Myomectomy for Diffuse Uterine Leiomyomatosis

Background. Diffuse uterine leiomyomatosis is a rare disease in which countless, poorly defined, and small nodules are present in most parts of the uterine myometrium. It frequently occurs in fertile women and causes infertility. A deep, median, longitudinal incision of the uterine corpus with the opening of the endometrial cavity, “extensive myomectomy,” is required to restore fertility. However, myomectomy may also be a risk factor for perinatal complications. We present a rare case of adhesive small bowel obstruction after extensive myomectomy for diffuse uterine leiomyomatosis. Case. A 37-year-old primigravida presented with sharp epigastric pain and vomiting at 21-week gestation. The patient had a history of extensive myomectomy for diffuse uterine leiomyomatosis. Abdominal radiography revealed moderate air fluid levels in the small intestine, and the patient was diagnosed with adhesive small bowel obstruction. The patient was also diagnosed with placenta previa. Bowel rest with intestinal tube was continued until delivery. Cesarean section was performed at 32-week gestation due to (i) prolonged fasting and total parenteral nutrition for conservative treatment and (ii) fear of sudden massive bleeding from placenta previa. Because the ileum was strongly adherent to the uterine scar from the previous myomectomy, adhesiolysis and enterectomy were performed. The placenta was uncomplicatedly delivered and the hemorrhage was well-controlled. Conclusions. Pregnancy with a history with extensive myomectomy for diffuse uterine leiomyomatosis should be carefully monitored because of the occasional occurrence of adhesive small intestine obstruction during pregnancy.

Successful Vaginal Delivery during Acute Small Bowel Obstruction: A Case Report and Review of the Literature

Small bowel obstruction during pregnancy is rare and can be detrimental to both mother and fetus. In most cases, management eventually involves surgical intervention. Little is known regarding optimal mode of delivery in those with bowel obstruction during pregnancy. We present a case of vaginal delivery during acute small bowel obstruction as well as a review of recent literature regarding mode of delivery in the setting of bowel obstruction. Our case and literature review demonstrates that in pregnancies complicated by small bowel obstruction, successful vaginal delivery can be achieved in those with stable maternal-fetal status.

Successful Laparoscopic Treatment of Small-bowel Obstruction in Early Pregnancy

Small-bowel obstruction (SBO) during pregnancy is uncommon and can be difficult to diagnose. Therefore, the condition is associated with significant maternal and fetal mortality. We report a case of successful laparoscopic treatment of SBO in early pregnancy. A 37-year-old woman presented with diffuse abdominal pain and vomiting at 8 weeks of gestation. She had a history of abdominal surgery. Exploratory laparoscopy was performed by a gastrointestinal surgeon because SBO, and specifically strangulated ileus, was strongly suspected. On entry into the abdomen, dilated small bowel was visible in the pelvis; this was attached to the pelvic wall and twisted near the right adnexa. The small bowel initially appeared dark and congested, but after releasing the adhesions, it regained its normal color, was viable, and peristalsis was observed. Therefore, bowel resection was not required. No recurrence was observed after food ingestion, and the patient was discharged 12 days after surgery.

Small bowel obstruction in pregnancy is a complex surgical problem with a high risk of fetal loss

INTRODUCTION

Small bowel obstruction (SBO) in pregnancy is rare and is most commonly caused by adhesions from previous abdominal surgery. Previous literature reviews have emphasised the need for prompt laparotomy in all cases of SBO because of the significant risks of fetal loss and maternal mortality. We undertook a review of the contemporary literature to determine the optimum management strategy for SBO in pregnancy.

METHODS

The MEDLINE® and PubMed databases were searched for cases of SBO in pregnancy between 1992 and 2014. Two cases from our own institution were also reviewed.

RESULTS

Forty-six cases of SBO in pregnancy were identified, with adhesions being the most common aetiology (50%). The overall risk of fetal loss was 17% and the maternal mortality rate was 2%. In cases of adhesional SBO, 91% of cases were managed surgically, with 14% fetal loss. Two cases (9%) were managed conservatively with no complications. Magnetic resonance imaging (MRI) was used to diagnose SBO in 11% of cases.

CONCLUSIONS

Based on our experience and the contemporary literature, we recommend that urgent MRI of the abdomen should be undertaken to diagnose the aetiology of SBO in pregnancy. In cases of adhesional SBO, conservative treatment may be safely commenced, with a low threshold for laparotomy. In other causes, such as volvulus or internal hernia, laparotomy remains the treatment of choice.

Uterine rotation: a cause of intestinal obstruction

Intestinal obstruction is an uncommon surgical emergency during pregnancy that affects seriously the prognosis of gestation. The underlying cause can be identified in the majority of cases and usually consists of adhesions secondary to previous abdominal or pelvic surgery, followed in order of frequency by intestinal volvuli. In recent years there have been no reports in which the gravid uterus has been the cause of intestinal obstruction. We report the case of a woman in week 33 + 4 of pregnancy who developed extrinsic compression of the colon secondary to uterine rotation and pelvic impaction of the head of the fetus.
