APPENDICITIS AND PREGNANCY

In 74,000 obstetrical patients at Los Angeles County Hospital the incidence of acute appendicitis in pregnancy was 0.05 per cent. In a study of 36 cases of clinically diagnosed appendicitis in pregnancy between 1956 and 1960, it was shown that the fetal and maternal morbidity and mortality were decreased when a definite operative procedure was done early. The difficulty in diagnosis is increased by the necessary consideration of pyelonephritis and twisted ovarian cyst. Rupture of the appendix increased hazards to maternal and fetal survival. It was noted also that threatened premature labor may indicate a ruptured appendix. Emergency operation with the use of antibiotics in such cases was effective therapy. The incidence of premature delivery was proportionate to the delay in operating. If operation was performed in less than eight hours after admission to the hospital, there was no maternal or fetal loss. A delay greater than eight hours resulted in a 17 per cent fetal loss in premature delivery and 4 per cent fetal loss of infants at term.     

Gall stones in sickle cell disease in the United Kingdom.

The prevalence of gall stones was studied prospectively by abdominal ultrasound examination in 131 patients with sickle cell disease aged 10-65 years. Of 95 patients with homozygous sickle cell disease, 55 (58%) had gall stones or had had a cholecystectomy. Gall stones were present in four out of 24 (17%) patients with haemoglobin S + C disease and two out of 12 (17%) with haemoglobin S beta thalassaemia. The presence of gall stones was not related to sex, geographical origin, or haematological variables and was not associated with abnormal results of liver function tests. Symptoms typical of biliary colic were reported by 32 out of 47 adult patients with gall stones, and cholecystitis or cholestasis was diagnosed in 18. Cholecystectomy was performed in 29 patients with good relief of symptoms in most cases. Postoperative complications were common, occurring in 10 of the 28 patients who could be evaluated, but not generally serious; they were considerably lessened by a preoperative exchange transfusion that reduced the haemoglobin S concentration to below 40%. It is suggested that all patients with sickle cell disease should be screened for gall stones and that elective cholecystectomy should be performed in those with symptoms or complications.     

The Prevention of Residual Biliary Calculi

Residual calculi following cholecystectomy may be expected in approximately seven percent of cases. The vast majority of these are overlooked during operation; truly re-formed stones are rare.Calculi are missed during cholecystectomy because of failure to explore the common bile duct. This is due to (1) the presence of silent choledochal stones, and (2) reliance on negative cystic duct cholangiograms in the presence of indications for common duct exploration.Overlooking of silent stones during cholecystectomy may be prevented by routine operative cholangiography. Ideally, false-negative cystic duct cholangiograms should be eliminated by the use of fluoroscopic cholangiography.Retained calculi following duct exploration may be prevented by (a) routine biliary endoscopy and (b) completion fluoroscopic cholangiography.Re-formation of ductal calculi can probably be prevented by appropriate biliary drainage procedures performed during the initial choledochotomy. Selection of patients for primary biliary decompression remains an experimental problem.     

Thalassaemia,iron, and pregnancy.

Haematological values of 35 pregnant women with beta-thalassaemia trait were followed during pregnancy. The discriminant function, calculated from haematological indices, was of no value in diagnosing beta-thalassaemia trait during pregnancy. Initially patients were given iron supplements only if the serum iron and total iron binding capacity levels indicated iron deficiency, but bone marrow biopsies performed in the first 22 patients at 32 weeks indicated deficient iron stores. These patients were therefore given iron irrespective of their serum iron level. All subsequent patients with beta-thalassaemia were also put on iron routinely at booking. Retrospectively the patients were divided into two groups. Patients in group 1 (18 patients) had received iron for less than 12 weeks, and their haemoglobin levels fell significantly during pregnancy (P less than 0-001). Haemoglobin levels in 16 patients who had received iron for more than 12 weeks (group 2), however, did not fall significantly during pregnancy (P less than 0-6). It is suggested (contrary to common practice) that patients with beta-thalassaemia trait should be given iron supplements during pregnancy. Serum folate and vitamin B12 levels did not change significantly in these patients and there was no increase in the incidence of maternal or fetal complications.     

胆囊切除术医源性胆管损伤的处理

目的:探讨开腹胆囊切除术医源性胆道损伤的诊断、手术时机和手术方式的选择。方法:对18例胆道损伤进行分析总结:分别施行了胆管修补、T管引流术10例,保守治疗2例,Roux-en-Y胆肠吻合术6例。结果:3例术后过早拔管发生吻合口狭窄,再次手术。1例因梗阻性胆管炎并发肝功能衰竭、多器官功能衰竭死亡。1例因胆肠吻合术后并发消化道出血、肝昏迷死亡。余术后良好。结论:尽早发现及正确处理对提高疗效和预防术后胆管狭窄起着决定性的作用。术中发现胆管损伤立即行端端吻合加T管引流;术后数天发现或多次胆道修补术失败者,则宜行规范的Roux-en-Y胆肠吻合术。     

Actue Cholecystitis Following Unrelated Surgery

In a series of 26 cases of acute cholecystitis occurring after an operation for an unrelated condition, 88% of the patients were over 50 years of age and males outnumbered females by 2 to 1. In some of the cases diagnosis was difficult and delay was responsible for the death of one patient. Acalculous cholecystitis occurred in 20% of the cases and in these gangrene or perforation supervened early in the course of the disease.Efforts should be directed to ensuring adequate hydration after operation; resumption of a diet low in fat may be important. Even in the absence of a history of biliary disease, there is a place for the radiological study of the biliary tract before major elective operations are performed. If gallstones are discovered on the occasion of the initial surgery, cholecystectomy should be performed whenever it is feasible. In any patient with postoperative cholecystitis early operation is generally indicated.     

Early cholecystectomy for acute cholecystitis

A series of 65 cases of acute cholecystitis from among 500 patients on whom cholecystectomy was performed by the author is presented. Early cholecystectomy was the operation of choice in 63 and cholecystostomy in two. The operative mortality for cholecystectomy was 1.6%; the postoperative morbidity was low and there were no serious complications such as common bile duct injury or biliary fistula. Operation for acute cholecystectomy is recommended within 48 hours of diagnosis to avoid serious complications such as perforation and suppurative cholangitis.     

INTRAVENOUS CHOLANGIOGRAPHY—Some Observations on the Use of Cholografin

Intravenous cholangiography with cholografin is a safe procedure, most useful for the study of patients who have had cholecystectomy and later have symptoms related to the biliary ducts.When jaundice or liver impairment is present, the examination is usually unsuccessful. However, these conditions are not absolute contraindications to the procedure. There may be failure to visualize the biliary ducts even in the presence of a normal liver.Planigraphy is helpful in eliminating confusing superimposed structures and when there is only faint visualization of the common duct.Intravenous cholecystography is only of questionable value as a supplementary examination to oral cholecystography. It may prove useful in certain instances when patients are unable to retain or absorb the oral media or where emergency operation is contemplated.

Postoperative assessment of cerebral neoplasms: the need for an early brain scan

Brain scans were performed on 40 patients who had had craniotomies for nonmalignant disease during the preceding 11 years. A significant decrease in radioactivity at the craniotomy site with time was found, and in nine patients studied five years post craniotomy there was no activity at all. Because of the frequent difficulty in interpreting the postcraniotomy brain scan when searching for recurrent tumours, it is recommended that baseline scans be obtained a few months after the operation to allow comparison of increased radioactivity at the craniotomy site with what may be seen on future brain scans.     

Estimation of gestational age and assessment of canine fetal maturation using radiology and ultrasonography: a review

Since the duration of pregnancy in the bitch is relatively short, it is critical that fetuses are fully mature prior to delivery for them to survive. For breeders to be able to prepare for normal whelpings and align medical care in case of emergency, an estimated due date is necessary. In cases where ovulation timing is lacking and there is a singleton fetus or oversize fetuses, it is necessary to ascertain gestational age prior to setting the date of Cesarean section. In high-risk pregnancies, where there is poor or no ovulation timing, determination of fetal maturation and gestational age will assist in determining if pregnancy has progressed long enough to allow delivery of viable puppies. In cases where bitches are receiving supplemental progesterone for pregnancy maintenance medications must be discontinued at an appropriate time to permit delivery of viable puppies. It also allows for estimation of the likelihood of fetal survival if the pregnancy is terminated due to failing bitch health, with subsequent surgical delivery of the fetuses. Use of breeding dates alone does not provide due dates with adequate accuracy. In cases where there has been inadequate or no breeding management or ovulation timing, estimation of due date can be performed at the time of pregnancy diagnosis, or closer to term. Radiography can be used to confirm pregnancy and facilitate determination of gestational age, beginning 45d after the LH surge. Ultrasonography can be used from 19 to 21d after the LH surge to term to confirm pregnancy and predict gestational age, and from 25 or 26d to term to assess fetal viability and fetal stress.     

Prospective study of human parvovirus (B19) infection in pregnancy. Public Health Laboratory Service Working Party on Fifth Disease.

OBJECTIVE--To determine the fetal infection rate and outcome of pregnancy among women who acquire infection with human parvovirus (B19) in the antenatal period. DESIGN--Prospective study of infected pregnancies till time of delivery or abortion with virological investigation of fetuses, neonates, and 1 year old infants. SETTING--England and Wales during 1985-8. PATIENTS--190 Pregnant women with serologically confirmed B19 infection in pregnancy, their fetuses, neonates, and 1 year old infants. RESULTS--Of 186 mothers who elected to go to term, 156 (84%) delivered a normal baby. Follow up of 114 of these infants to the age of 1 year disclosed no appreciable abnormalities, although 27 had serological evidence of intrauterine infection. The overall fetal loss rate (30 cases; 16%) was similar to that in an uninfected antenatal sample (unmatched), but there was a pronounced excess of fetal loss in the second trimester in the B19 infected mothers (11.8%; 95% confidence interval 6.8% to 17.8%). Based on virological findings in the aborted fetuses the risk of fetal death due to B19 in an infected pregnancy was estimated to be 9%. The transplacental transmission rate was estimated to be 33%. CONCLUSIONS--Most women with B19 infection in pregnancy had a satisfactory outcome, but there was nevertheless a substantial risk of fetal loss in the second trimester. In view of the absence to date of any evidence of damage to babies who survive maternal infection therapeutic termination of pregnancy is not indicated.     

Perinatal outcome of pregnancies in women aged 40 and over

Perinatal outcome of pregnancies at forty and over was analyzed starting from the diagnosis of pregnancy to seven days following delivery. Retrospectively, pre-gestational health and reproduction status were dealt with, as well as the course of pregnancy, deliveries, and newborn children (study group). The control group was composed of pregnant women aged 20 to 29, who were identical to study group in terms of parity. Statistical data processing was done by means of chi2-test, and contingency 2 x 2 tables. The difference was significant if p < 0.05. Out of 2,099 diagnosed wanted pregnancies at forty and over, 415 (19.8%) had a miscarriage, in 33 (1.6%) an artificial abortion was performed after determining the fetus karyotype and 1,651 (78.2%) of pregnant women delivered. In 66.2% of pregnancies the fetus karyotype was determined and in 33 (2.5%) fetuses chromosomal abnormalities were found Incidence of deliveries at 40 and over is 1.38%, which is a 35.6-percent increase in the last ten years. Nullipara and pluripara had an increase, and multipara had a decrease. Pre-gestational health and reproduction status in study group is lower than in control group. Complications during pregnancy: threatened abortion, EPH gestosis, placenta praevia, gestational diabetes, late fetal death are more frequent than in control group (p < 0.05). In intrapartal terms, more frequent were induction of delivery, meconium-stained amniotic fluid, fetal distress, operative vaginal deliveries, and Cesarean section (p < 0.05). In neonatal outcome there are more premature infant, there are more VLBW, LBW, SGA, newborn with low Apgar index values, and the total perinatal death is greater than in the control group (p < 0.05). In perinatal terms, (from the diagnosis to the seventh day following delivery) 1,617 children survived (77.0%), meaning that perinatal loss was 482 (23.0%). Authors conclude that pregnancy at 40 and over is a high-risk pregnancy. There is a high risk of pre-gestational and gestational complications, and perinatal loss is high. Therefore, those pregnancies are not desirable from the medical point of view.     

External biliary fistula.

External biliary fistulas, once common, are now rare: before the present report of 4 cases only 27 cases have been reported in the English literature since 1900. Review of the records of four patients with external biliary fistula confirmed its occurrence in patients over 50 years of age and the variable site for operning of the fistulous tract. Cholecystectomy provided successful treatment in three of the four patients but the fourth was too ill to undergo an operation; in general, definitive treatment is cholecystectomy, together with excision of the fistulous tract if this takes a direct path through the abdominal wall from the gallbladder, or curettage if the course is devious.     

Appendicitis in pregnancy.

Over a 9-year period at one hospital 25 appendectomies were performed during pregnancy. In 20 cases the appendix was acutely inflamed. All mothers survived. Two women aborted and two went into premature labour. One of the premature infants survived. The fetal loss associated with acute appendicitis was 15%. Early diagnosis and operation is essential.     

Effects of legal termination on subsequent pregnancy.

Two hundred and eleven patients who had undergone vaginal termination and were pregnant again were investigated; 43-2% had become pregnant within one year of termination. The overall fetal loss in the 211 patients was 17-5% compared with 7-5% in a group matched for parity but consisting of patients who were pregnant after a spontaneous abortion. Altogether 4-3% of pregnancies after legal abortion ended as first trimester abortions, 8-5% as second trimester abortions, and 13-7% in premature delivery. Among 11 women whose cervices had been lacerated at the time of legal termination the fetal loss in subsequent pregnancy was 45-5%, and only one pregnancy went beyond 36 weeks. Routine Shirodkar suture may be beneficial when the cervix is known to have been damaged at legal abortion. Several patients had asked that their general practitioner should not be told of their termination, and such patients may not admit their termination during a subsequent pregnancy, which could thus be jeopardised. No evidence was found to suggest that infants of patients with a history of legal termination are small for dates.     

High-risk pregnancy and hypoluteoidism in the bitch

High-risk pregnancies are those in which the prevalence of maternal, fetal and/or perinatal morbidity or mortality is likely to be higher than that of the general obstetrical population. Some maternal characteristics associated with risk to maternal, fetal and/or perinatal health are readily identifiable prior to conception, such as advanced maternal age, brachycephalic breed, or a previous history of pregnancy loss. Others, such as gestational diabetes or a singleton litter, are recognized after conception. Early recognition of the problem (i.e. the risk), anticipation of the potential sequelae, and development of an aggressive management scheme are essential for a successful outcome of a high-risk pregnancy. A previous history of pregnancy loss is a high-risk factor for recurrence during subsequent pregnancies. Infection is a common cause. In some instances, recurrent pregnancy loss is associated with low serum concentrations of progesterone. Although the mechanism(s) by which this occurs is not fully understood, the situation has been called hypoluteoidism. Whatever the cause of the risks to pregnancy, the goals of managing high-risk pregnancies are to optimize maternal, fetal and perinatal health, so as to maintain maternal health throughout pregnancy and lactation and maximize the number of healthy pups surviving to weaning age.

Application of Ureteroscope in Emergency Treatment with Persistent Renal Colic Patients during Pregnancy

Background

Although the application of ureteroscopy in the treatment of ureteral calculi during pregnancy has been on the rise, for persistent renal colic patients without ultrasound-detected ureteral calculi, it may represent a clinical dilemma due to the potential risks for both mother and fetus.

Objective

The aim of the present study is to present our experience with the application of the ureteroscope in the emergency treatment of persistent renal colic patients during pregnancy.

Methods

From March 2009 to September 2014, a total of 117 pregnant women who received ureteroscopy for persistent renal colic were retrospectively analyzed. Patients were divided into three groups according to duration of the persistent renal colic: Group A (within 12 hours; 24 cases); Group B (12 to 24 hours; 76 cases); and Group C (more than 24 hours; 17 cases). The stone-free rate, complications, and other qualitative data were analyzed.

Results

Of the 117 patients, 31 patients who were found not to have renal or ureteral calculi received ureteroscopic double-J (DJ) stent insertion, whereas 86 patients who were found with ureteral calculi received ureteroscopic lithotripsy (URSL) and DJ stent insertion. Among them, 24 patients (27.9%) were found with ureteral calculi by ureteroscopy rather than ultrasound. In addition, 73 patients (84.9%) had complete fragmentation of calculi; 12 patients (10.3%) had a threatened abortion (the rates of threatened abortion in Groups A, B and C were 8.3% vs. 6.5% vs. 29.4%; Group C compared with Groups A and B, p<0.05), and one patient (1.2%) had urosepsis (in Group C). However, these complications were cured with conservative treatment, without postpartum infant and maternal complications.

Conclusion

For pregnant patients with persistent renal colic/ureteral calculi and hydronephrosis, ureteroscopic DJ stent insertion and URSL are effective and safe options when conservative treatment fails, even if no urinary calculi were found by ultrasound. At the same time, for patients with persistent renal colic during pregnancy, early application of ureteroscopy may reduce the risk of preterm birth.
