Abstract
Background
Laparoscopic surgery during pregnancy is a challenging procedure that most surgeons are reluctant to perform. The objective of this study was to evaluate whether laparoscopic appendectomy and cholecystectomy is safe in pregnant women. The management of these situations remains controversial. We report a single center study describing the successful management of 16 patients during pregnancy.
Methods
More than 3,356 laparoscopic procedures were performed in our institutions between May 1990 and June 2005. Sixteen of these patients were operated on in the second and third trimester between 22 and 32 weeks of estimated gestational age. We performed 11 laparoscopic appendectomies and 5 laparoscopic cholecystectomies. We also reviewed the management and operative technique used in these patients.
Results
In this study, the laparoscopic appendectomy or cholecystectomy was performed successfully in all patients. Three patients were in their second trimester, weeks 22, 23, and 25, and 13 were in the third trimester, weeks 27 (three patients), 28 (five patients), 31 (three patients), and 32 (two patients). No maternal or fetal morbidity occurred. Open laparoscopy was performed safely in all patients and all patients delivered healthy babies.
Conclusion
From our experience laparoscopic management of appendicitis and biliary colic during pregnancy is safe, however the second trimester is preferable for laparoscopic cholecystectomy. Pregnancy is not a contraindication to the laparoscopic approach to appendicitis or symptomatic cholelithiasis. We believe that laparoscopic operations, when performed by experienced surgeons, are safe and even preferable for the mother and the fetus.

Introduction
Acute appendicitis and symptomatic cholecystolithiasis are common nonobstetrical emergencies in pregnant women [1, 2] and occurs in about 1 to 500 pregnancies [3].
Acute appendicitis occurs with the same frequency in gravid and in nongravid females of the same age, leading to appendectomy in one out of every 1,500 pregnancies [1–5]. Anatomically, the appendix is displaced out of the right lower quadrant to the right lateral upper quadrant. Leukocytosis is common in uneventful pregnancy [4, 6, 7]. Diagnostic studies, including ultrasound, are of little help; only a physical examination is reliable. Laparoscopic exploration can help to the diagnosis and be therapeutic. Delay with resultant appendiceal rupture with peritonitis has fetal consequences [8]. Peritonitis after perforation increases the risk of unstable gestation and fetal losses are up to 20% in cases of perforated appendicitis and up to 35.7% in generalized peritonitis compared to less than 5% in case of uncomplicated acute appendicitis [6]. Thus, clinical suspicion of acute appendicitis during pregnancy is an indication for surgical exploration [2].
Biliary tract disease occurs in about 1 to 6 out of 1,000 pregnancies and requires surgical intervention less frequently, partly due to the availability of effective nonsurgical therapeutic alternatives [1, 9]. Cholecystectomy is required in about 40% of pregnant women with symptomatic biliary colic [10]. Pregnancy may predispose women to gallbladder disease by increasing stone formation and possibly increasing symptoms in women with preexisting cholelithiasis [9, 11]. Fetal losses for cholecystectomy is approximately 5% [4]. However, acute biliary pancreatitis was associated with a 15% maternal mortality and up to 60% fetal losses [4].
Although published studies have described successful procedures, laparoscopic surgical intervention remains limited [12]. In many minds, pregnancy is still considered to be a contraindication and physicians have a tendency to postpone surgical intervention for as long as possible, best until after delivery [13, 14]. However preterm delivery, birth defects, 5-min Apgar score, and low-birth-weight after laparoscopic appendicectomy or cholecystectomy are possible without significant increase in morbidity or mortality [15, 16]. We present here our experience in laparoscopic management of acute appendicitis and symptomatic biliary colic in the pregnant women.
Materials and methods
During a 15-year period from 1990 to 2005, the clinical files of patients who were operated laparoscopically were reviewed. All the charts of patients that were taken to the operating room for appendix or gallbladder disease during pregnancy were analyzed. Clinical and pathology reports were reviewed to confirm the diagnosis and to obtain maternal outcome. Pregnancy outcome information, such as birth weight, fetal losses, gestational duration, congenital malformations, stillbirths, and neonatal deaths, were obtained by directly contacting the patient or the patient’s obstetrician.
The Hasson technique of open laparoscopy was performed systematically. To prevent puncturing the gravid uterus the position of the initial trocar was controlled by ultrasound. The subsequent trocars were positioned as needed (Fig. 1). Pneumoperitoneum pressure was limited to 10–12 mmHg and kept as low as possible. Laparoscopic appendectomy and cholecystectomy were performed using a three-trocar technique with a 30°-angled optic. Both laparoscopic appendectomy and cholecystectomy were performed in a supine position and in the left lateral decubitus to prevent uterine compression of the inferior vena cava. Pneumatic sequential stockings were placed on the patient in the operating room and their use continued while the patient remains hospitalized. All patients received prophylactic low-dose heparin preoperatively. Administration of tocolytic agents (hexoprenaline-beta-2 sympathomimetic) and perioperative monitoring of fetal heart were routinely performed. No intraoperative cholangiography was performed.
Results
Out of more than 3,356 laparoscopic interventions (600 appendectomies and 1,800 cholecystectomies) in our institution, we found 16 patients who were operated during pregnancy. Eleven women underwent laparoscopic appendectomy and five underwent laparoscopic cholecystectomy. The operation was performed in the second and third trimester of pregnancy between weeks 22 and 32. Three patients were in the second trimester and 13 in the third trimester.
For the appendectomy, the diagnosis was a suspicion of acute appendicitis in all the cases. The diagnosis was made clinically. Ultrasonography was not done routinely and was positive for acute appendicitis in only one out of four cases. At the time of surgery, average gestational age was 26 weeks for appendicitis. Average operation time was 45 min (35–60 min). In seven out of the eight cases the pathologist confirmed an acute appendicitis without perforation. In one case, the appendix was normal. For the cholecystectomy, indication for laparoscopy was acute cholecystitis with the presence of stones confirmed by ultrasonography in all the cases. Pathological examination of the gallbladder documented acute cholecystitis in all cases. At the time of surgery, median gestational age was 28 weeks. Operation time was 75 min (55–90 min).
For all the patients, no intraoperative or postoperative complications occurred. Recovery was rapid and uneventful. The average hospital stay was 2.5 days for appendectomy and 4.5 days for cholecystectomy. No preterm labor occurred and all patients delivered normal healthy babies.
Discussion
Nonobstetrical surgery during pregnancy was shown to be safe in a study over 5,405 operations on pregnant women without increases of congenital malformations or stillbirths, but with higher incidences of very-low, low-birth-weight infants, and death of infant during the first 168 days [17, 18]. The laparoscopic procedure was safely performed in pregnant females in several published studies [2, 13, 19, 20], although the gravid condition has long been seen as a contraindication for laparoscopic surgical procedures [21]. Concerns included teratogenicity in the first trimester and preterm delivery during the second and third trimester. Direct uterine trauma, decreased uterine blood flow due to the pneumoperitoneum, and toxic narcotics drugs are possible causes [22–24]. The second trimester is considered the safest period to perform any surgery [25] because the uterus, due to its small volume, is less susceptible to traumatic injuries. But recently, some studies [26–34] have demonstrated that selected laparoscopic procedures can be performed safely during pregnancy even in the third trimester. Complications such as fetal loss and premature labor do occur, but can be kept around 5% in the second trimester with the use of appropriate techniques. Guidelines were developed to ensure no increases in morbidity for the pregnant patient and to ensure that the safety of the fetus was not jeopardized [23, 35, 36].
There is a general consensus that laparoscopic procedures are safest when performed during the second trimester of pregnancy [21, 26, 37]. Hunter et al. [39] investigated the physiological impact of a CO2 pneumoperitoneum in these clinical settings. They concluded that a CO2 pneumoperitoneum created minimal impact on the patient and the fetus when using intraabdominal pressure of 15 mmHg or less [38, 39, 40].
It was reported that intrauterine placement of a Veress needle can result in damage to the gravid uterus when creating a pneumoperitoneum in the pregnant patient [2, 14]. The use of Hasson’s trocar for open laparoscopy is usually considered safer especially with increased gestation age. It is essential to monitor the gravid patient and the fetus during the laparoscopic intervention. The gravid patient should be monitored carefully for oxygenation and hemodynamic status. Arterial blood gases and maternal end tidal CO2 should be obtained frequently Administration of tocolytic agents and perioperative monitoring of fetal heart tones should be routinely performed [23].
There are now numerous reports of laparoscopic appendectomies and cholecystectomies being performed in pregnant patients [41]. Almost all of these procedures were performed during the first and second trimester. Reported outcome studies showed that maternal morbidity is anecdotical and the fetal losses are rare. Potential advantages of laparoscopic appendectomy and cholecystectomy in the pregnant patient include decreased fetal depression due to lessened postoperative narcotic requirements, lower risks of wound complications, and diminished postoperative maternal hypoventilation [2].
Although surgical management of acute cholecystitis or choledocholithiasis is more accepted, surgical management of symptomatic cholecystolithiasis remains controversial. Recently a multicenter study compared medical vs surgical management of symptomatic cholelithiasis. In that study, surgery decreased the number of days in hospital and even reduced the rate of labor induction and preterm deliveries [42]. The nonsurgical management led to suboptimal clinical outcome in up to 38% of the women [42, 43]. That study clearly argues in favor of changing the management of gallstone disease during pregnancy from conservative or open cholecystectomy toward early laparoscopic cholecystectomy. We did not modify our management of choledocholithiasis in the gravid patient. As with other authors, our experience is limited in this particular setting and none of the patients in that study needed a common bile duct exploration for choledocholithiasis. We believe that using the appropriate protective measures, these patients are best managed by laparoscopic cholecystectomy with cystic duct cannulation and postoperative endoscopic retrograde cholangiopancreatography [25].
We suggest the following guidelines to improve the safety of laparoscopic procedures:
-
1.
Obstetrical consultation should be obtained preoperatively.
-
2.
When possible, operative intervention should be deferred until the second trimester when fetal risk is lowest.
-
3.
The laparoscopic procedure should be performed in supine position and in the left lateral decubitus to prevent uterine compression of the inferior vena cava. The degree of reverse Trendelenburg’s position should be as low as possible for visualization of the gallbladder and appendix.
-
4.
To prevent puncture of the gravid uterus it is safer to use the open Hasson trocar technique.
-
5.
Pneumoperitoneum pressures should be minimized to 8–12 mmHg and not allowed to exceed 15 mmHg.
-
6.
Administration of tocolytic agents and perioperative monitoring of fetal heart tones should be routinely performed.
-
7.
If an intraoperative cholangiography is necessary, the uterus should be protected with a lead shield. Fluoroscopy should be utilized selectively.
-
8.
Because pneumoperitoneum enhances lower extremity venous stasis already present in the gravid patient and pregnancy induces a hypercoagulable state, pneumatic compression devices must be utilized.
Conclusion
Laparoscopic surgery during pregnancy is not common and many surgeons are still reluctant to perform laparoscopic procedures. Nevertheless, we conclude that in a patient with strict indication, pregnancy is not a contraindication and laparoscopy can safely be performed in any trimester. Our results support laparoscopic management of appendicitis and symptomatic cholelithiasis during pregnancy, preferably in the second trimester. However, further study is required to better understand the effects of prolonged carbon dioxide pneumoperitoneum on fetal physiology.
