Comparative study of Filshie clip and Pomeroy method for postpartum sterilization.

A prospective randomized comparison of the peri-operative complications and long-term sequelae between the Filshie clip and Pomeroy methods was undertaken in 200 postpartum women at Tri-Service General Hospital, Taipei, Taiwan. The peri-operative complications in either group were mild and infrequent. One pregnancy in the Pomeroy group was reported after follow-up for 24 months. No significant difference between the two groups was found in respect to long-term sequelae.

A method of Pomeroy tubal ligation reanastomosis.

A method of reanastomosis of the uterine tube after Pomeroy tubal ligation is presented. The pregnancy rate was 69%. The viable birth rate was 38%, with 1 ectopic pregnancy, 2 patients pregnant, and 1 patient lost to followup at the time of this report.

Recent advances in female sterilization.

Advances in female sterilization have been made over the last five years in both its techniques and medico-social acceptance. Prior to 1970, the majority of tubal sterilizations were carried out by partial or complete surgical excision of both tubes by laparotomy in most cases, or by partial salpingectomy by an anterior or posterior colpotomy in selected cases. The traditional operations by the abdominal route comprised the Madlener method, the Pomeroy method, the Irving method and the Aldridge method. These methods will not be discussed further.

10-year survey of 485 sterilisations. Part I--Sterilisation or hysterectomy?

A survey was made of all sterilisations performed in an obstetric and gynaecological unit in Dunfermline in 1965-74 to determine the outcome and complications. Altogether 547 women were sterilised by the modified Pomeroy method, and 485 (88.7%) were interviewed and examined. No sterilisation was followed by serious complications, and the incidence of even minor complications was low (4.12%). There were no subsequent pregnancies. Altogether 57 women had to be referred for gynaecological operations in the years after sterilisation but only 18 of these had to have hysterectomies. At interview 59 women were found to have gynaecological symptoms (menstrual disorders in 46), and examination showed that 83 women had a gynaecological condition, which was in most cases unsuspected by the patient. Most of these conditions were minor but three women had carcinoma-in-situ of the cervix. Although 46 women suffered menstrual disorders after sterilisation 104 had done so at some time before the operation. These results therefore offer little support for the wider use of hysterectomy as a form of sterilisation.

[Failed postpartum sterilisation--a comparison of 5 methods].

A comparison of the standard Vienna method of postpartum sterilisation (3,580 patients with 18 failures and a sterilisation failure rate of 5.03/1,000) with 4 other methods at Paarl Hospital is presented: the Pomeroy method (892 patients with 19 failures and a sterilisation failure rate of 21.31/1,000); the total fimbriectomy method (1,578 patients with 23 failures and a sterilisation failure rate of 14.58/1,000); the Filshie clip method (808 patients with 18 failures and a sterilisation failure rate of 22.28/1,000); and the Irving method performed at caesarean section (456 patients and 1 failure). As no totally permanent technique exists to prevent pregnancy, a plea is lodged for legalised abortion after failed sterilisation.

Tubal sterilization by a combined laparoscopic and external technique: preliminary report on 75 cases.

A preliminary report is given on a new laparoscopic sterilization procedure. By a double-puncture method, a loop of tube is brought out of the abdomen through the suprapubic incision. The loop is then resected by a modified Pomeroy method. Between Octorber 1976 and June 1978, 75 sterilizations were performed without any major problem. Sterilization failed in one case when one tube could not be seen. All recoveries were uneventful. Safety, effectiveness, simplicity, and potential reversibility seem to be the qualities of this method.

The safety of field tubal sterilization: a cohort study.

A cohort study on female sterilization has been carried out to compare the safety of field-based procedures with hospital-based procedures. A total of 217 women were recruited, consisting of 103 field-based and 114 hospital-based acceptors. Married and healthy women 20-45 years of age, having at least two living children, not obese, no history of major abdominal surgery, no signs of acute pelvic inflammatory disease, and no contraindication to ketamin were included in the study. Women with severe pelvic adhesions encountered during surgery were excluded from the study. The ambulatory procedure was used for all acceptors except those who were sterilized in hospital immediately after delivery. They were asked to come to th Sarjito Hospital (hospital-based) or Puskesmas (primary health care center or field-based), after fasting the night before. Ketamin, 50-100 mg, was used intravenously for general anesthesia. Minilaparotomy followed by the Pomeroy method was used for standard female tubal sterilization. Tetracycline, 3 x 500 mg was given for five days prophylactically. Follow-up was carried out one and six weeks after the day of operation. Data were processed with an IBM-compatible PC, using version 3.0 SPSS program. Students t-test, chi-square test and relative risk (95% confidence limit (CL)) were used for statistical analysis. Both groups were comparable in terms of age, parity, body weight, and body height. The duration of operation in the field was somewhat longer than that in the hospital, i.e. 24.58 vs 21.14 minutes.(ABSTRACT TRUNCATED AT 250 WORDS)

The reversibility of female sterilization with the use of microsurgery: a report on 102 patients with more than one year of follow-up.

A prospective study of 102 patients who underwent a reversal of sterilization between January, 1977, and February, 1982 revealed a pregnancy rate of 68% after more than 1 year of follow-up. The term delivery, abortion, and ectopic pregnancy rates were 52%, 11%, and 5%, respectively. The most reversible procedure was placement of the Falope ring (83% term delivery), and the least reversible was fimbriectomy (29%). The use of the microscope in performing tubal operation was associated with term delivery rates (60%) higher than those when no microscope was used (44%); this was particularly significant after tubal cautery (50% versus 25%). A total remaining tube length of 6 cm or more after previous sterilization resulted in a much better (74%) term delivery rate after microsurgical procedures than that in patients with shorter tubes (44%). The most successful site for tubal anastomosis was isthmus-isthmus and cornu-isthmus, with 81% and 67% term delivery rates, respectively.

The microsurgical basis of Fallopian tube reconstruction.

A rational approach to the reconstruction of the Fallopian tube, blocked either intentionally or by disease processes, can only be made on the basis of sound anatomical and physiological understanding. It would accordingly not be logical to expect the tube to function normally again after too great a disorganization by sterilization procedures followed by traumatic restorative operations. It is therefore recommended that any sterilization should be carried out by a midtubal atraumatic Pomeroy method, tissue being conserved for possible future reconstruction, and that a proven microsurgical technique be utilized for the best results of reconstruction to be obtained. This paper briefly details the anatomy and physiology of the Fallopian tubes, evaluates a microsurgical tubal repair in the rabbit, reports a series of tubal repairs in women, and suggests a working protocol for future tubal surgery.

Reconstruction of fallopian tubes in previously sterilized patients.

Restoration of tubal patency after surgical sterilization in which the luminal continutiy is interrupted requires either uterine implantation of the patent distal segment or resection and end-to-end anastomosis of patent adjacent segments. Although it is logical to assume that after most tubal ligations the intramural segment remains normal and end-to-end anastomosis is possible, both segments should be evaluated and tested prior to the plastic reconstruction. The results of 178 operations collected from the literature and the author's 23 attempts at surgical reversal of previous tubal operations for surgical sterilization were described. The over-all pregnancy rate after resection and end-to-end anastomosis was 39.0%; after uterotubal implantation, it was 19.4%. The latter procedure was performed in 60% of the patients. The small series of reports makes it difficult to evaluate conception rates or to judge the merits of specific reconstructive operative techniques.

Postpartum sterilisation by the Irving technique. A report of 200 cases at Paarl Hospital, CP.

Sterilisation by the Irving procedure accompanying caesarean section was the favoured form of sterilisation at Paarl Hospital from 1971 to 1985. No subsequent pregnancies have been reported from the 200 cases and this success is compared with sterilisation failure rates of 1.35% with the Pomeroy method, 1.27% with the total fimbriectomy method, 0.41% with the Vienna or modified Pritchard method, and 0.89% with the Filshie-clip method: Irving sterilisation is accordingly advised as the method of choice at the time of caesarean section.

Tubal ligation and pregnancy: mechanism of recanalization after tubal ligation.

The mechanism of recanalization after resection of a segment of the fallopian tube by the Pomeroy sterilization method is discussed. At the level of resection, the epithelial lining of the fallopian tube tends to regenerate, covering the split ends and planes of cleavage of the resected surfaces and forming slitlike spaces and blind pouches lined by tall columnar cells. Scarring and subsequent retraction of both severed ends of the tubes tend to result in approximation; in some cases, the resected ends and the epithelial lining bridge the gap between the lumina, re-establishing patency of the tube. Surgical procedures that prevent approximation of the resected ends of the fallopian tubes or methods that seal the lumina should produce failure rates lower than those obtained with the classic Pomeroy sterilization method.
