Vasa previa.

An active obstetric service can expect to have one perinatal death each year due to vasa previa. Unfortunately, little has been done to improve the diagnosis and treatment of this condition, which presents no risk to the mother but is often fatal to the fetus. The various clinical pictures which can be associated with vasa previa are presented, along with a discussion of the techniques readily available for making the diagnosis: palpation and visualization, amnioscopy, fetal heart monitoring, and various tests for the presence of fetal hemoglobin.

Laparoscopic tubal sterilization by the "burn only" technic.

A 5-year combined experience of 2857 cases of the "burn only" technic for laparoscopic tubal sterilization is reviewed. One method failure resulted in an ectopic gestation. There were no operator errors. One laparotomy 36 hours after the sterilization procedure was done. No hemorrhagic complications and no bowel burns were encountered. From a review of the literature and the results presented here, it seems that adequate coagulation of a generous segment of the tube is the critical factor in preventing subsequent pregnancies. Tubal division or resection appears to offer no improvement in efficacy, and when tissue is obtained for pathologic confirmation, it is often of no value. When coagulation plus division or resection is performed, the incidence of hemorrhagic complications and bowel burns increases markedly.

Documents and documentation in laparoscopy.

Some form of documentation of laparoscopic findings is essential in the proper management of the patient. We have found a simple outline form with a schematic drawing of the pelvis to be invaluable in emphasizing the need for a systematic and thorough endoscopic examination and in providing an excellent method of recall. Photographic documentation is primarily of value to those physicians involved in research or educational programs. In addition, we have found it helpful to give the patients a printed description of the procedure beforehand, as well as written instructions concerning preoperative arrangements and postoperative care.

Risks of laparoscopic fulguration and transection of the fallopian tube.

The more common methods of laparoscopic sterilization involve transection of the fallopian tubes. There are, however, a number of cases accumulating in which coagulation without transection has been employed. The risks of bleeding requiring the use of laparotomy are considerably reduced with this technic. There is no increased risk of electrical injury. The pregnancy rate is essentially the same in both methods. It is suggested that failures with tubal transection may be secondary to fistula formation and an inherent problem, whereas the failures with coagulation without transection are secondary to inadequate coagulation and are therefore more easily prevented.

Hospitalization for laparoscopy. The exception rather than the rule.

After studying a series of patients who underwent laparoscopy, the authors found that they are currently hospitalizing only 6.6% of them. They found that more patients are hospitalized for diagnostic laparoscopy than for surgical laparoscopy because of the potential need for laparotomy.

Laparoscopy in the obese patient.

A series of 49 patients weighing over 200 pounds is described, and a technique essential to successful care of obese patients is given. The ability to determine the intra-abdominal location of the Verres needle in order to create a physoperitoneum is the most important consideration.

The natural history of an hematosalpinx.

A patient who had experienced an actopic pregnancy and subsequent salpingectomy was found to have an ectopic pregnancy, presenting as an hematosalpinx, in the remaining fallopian tube. The diagnosis was made at the time of laparoscopy, and the patient refused definitive surgery. Fourteen months later she achieved an intrauterine pregnancy, and repeat laparoscopic examination revealed an essentially normal pelvis and fallopian tube. This is evidently the first case report of a pregnancy occurring through a fallopian tube that had had a previous ectopic gestation and in which no surgical procedure was performed on the affected tube.

Indications, contraindications and complications of laparoscopy.

The primary use of laparoscopy is as a surgical tool, with sterilizations being the overwhelming indication. The laparoscope is used less frequently as a non-surgical tool, with the major indication being for diagnosing infertility and/or amenorrhea, and for evaluation of obscure pelvic pain. There would seem to be several indications for laparoscopy that have been neglected, these being in confirming the diagnosis of acute pelvic inflammatory disease; in the evaluation of malignancies and abdominal-pelvic trauma; and the surgical treatment of pelvic pain. Lapar-The majority of these contraindications are relative, and depend soley on the laparoscopist's ability and his clinical judgment. The problems of hernias seem to have been over-emphasized. The laparoscopist should be aware of potential problems with umbilical hernia, and he probably can ignore hiatal hernias except when they are large and quite symptomatic. However, generalized abdominal peritonitis, significant hemoperitoneum with intestinal obstruction are felt by most authors to be absolute contraindications. The most frequent complications of laparoscopy involve the physoperitoneum. Except for cardiac arrest the most serious complications involve electrical burns to small bowel.
