Comparative study of different routes of hysterectomy

Background: To compare the various routes of hysterectomy and find the most commonly performed hysterectomy type and the various complications associated with each. Methods: This prospective study was carried out in the department of Obstetrics and Gynaecology, N.S.C.B. medical College, Jabalpur during June 2007 to August 2008. A total of 174 cases included in the study. The women were divided into three groups depending on the surgical approach: the abdominal group consisted of women who underwent hysterectomy via a suprapubic or median incision; the laparoscopically assisted vaginal hysterectomy (LAVH) group consisted of women who underwent vaginal hysterectomy assisted by laparoscopic procedure (excluding uterine artery ligation) and vaginal hysterectomy. Results: The indications of hysterectomy differed among groups. Four main indications in the cases coming to medical college: Fibroid, DUB, Genital prolapse and PID. Prolapse was a more frequent indication for vaginal hysterectomies; however, abdominal hysterectomies or Laparoscopically assisted vaginal hysterectomies were used in 16 out of the 76 cases that involved only prolapse. Fibroids were more frequently an indication for abdominal or laparoscopic assisted vaginal hysterectomy. Conclusion: The vaginal route has significant advantages over LAVH and abdominal hysterectomy and should be the route of first choice. Hence there is a tremendous scope for improvement by careful preoperative assessment, meticulous surgical techniques and proper postoperative care in order to reduce the complication rate. study different routes of A 174 cases were included in the Hysterectomy was by route, vaginal route and LAVH in 102, and 9 cases


Introduction
Hysterectomy, a Simple concept yet a procedure that has various physical, psychological and emotional implications for the women that undergo the procedure for some, it means an end to catamenial pain and inconveniences; for others it represents an abrupt unwanted termination of the potential for spontaneous procreation [1].
Hysterectomy is one of the most common major operations in women, and it is therefore vital to make an evidence based decision to choose the appropriate technique of hysterectomy. For years the abdominal route remained the unquestioned route for a hysterectomy with the vaginal route being used in less than a fourth of the population, in the presence of uterovaginal prolapse, and in the absence of the possible need for oophorectomy. This persisted through the years in spite of evidence that was forth coming in favor of the vaginal route [2, 3,4].
Once the decision has been made to proceed with hysterectomy, the physician must then decide whether the procedure will be performed abdominally, vaginally or with laparoscopic assistance. The route chosen should be the one that best accomplishes the procedure in a particular patient in question. The surgeon must also give consideration to surgical experience and expertise, as well as the patients disease process. How the gynecologist chooses the route of hysterectomy varies between surgeons. Absolute and relative contraindications for vaginal hysterectomy have been proposed [5].
It has been suggested that LAVH offers advantages over vaginal hysterectomy. One study randomized patients who were candidates for vaginal hysterectomy to either LAVH or standard vaginal hysterectomy. All procedures were performed on an outpatient basis, with patients included who had a uterine size up to 16wks gestational size. Hysterectomy still incurs a notable complications rate, with one fourth to one half of women experiencing one or more complications. Pelvic surgery risks one easily understood, considering the anatomy and technical details.
Opening the vaginal cuff contaminates the peritoneal cavity to some degree with the upper vaginal bacterial flora. The bowel, bladder and ureters and close to the lines of incision, clamping and suturing [6]. The present study entitled "Comparative study of different routes of hysterectomy" was undertaken to compare the various routes as well as the perioperative complications and outcome associated with each procedure.

Materials and Methods
Place & Type of Study: The present study entitled "Comparative study of different routes of hysterectomy" was conducted in the department of Obstetrics and Gynaecology N.S.C.B. Medical College Jabalpur from June 2007 to Aug 2008. A total of 174 cases included in the study .This is an observation prospective study.

Patients selection
Inclusion & Exclusion criteria  All women with benign gynecological disorders and planned for hysterectomy irrespective of their age.  Women who have undergone hysterectomy  Women were excluded if their primary diagnosis were related to cancer or pregnancy.  Women who had oophorectomies concurrently with hysterectomy were included.

Surgical Procedures:
If other procedures were done concurrently with the hysterectomy like vaginal repairs, appendicectomy or cholecystectomies were included. All women received prophylactic antibiotics at the beginning of the operation.
The women were divided into three groups depending on the surgical approach: the abdominal group consisted of women who underwent hysterectomy via a suprapubic or median incision; the laparoscopically assisted vaginal hysterectomy (LAVH) group consisted of women who underwent vaginal hysterectomy assisted by laparoscopic procedure (excluding uterine artery ligation) and vaginal hysterectomy. Laparoscopic conversion was defined as any laparotomy procedure performed for any reason in the vaginal and LAVH group. The indications of laparoconversion were recorded.
The indication of surgery, type of anaesthesia given and operative time in hours was noted. Intra and postoperative complications associated with each procedure were recorded. Also documentation regarding blood transfusion during surgery was done. Minor post op. complications like post op. spotting, fever, UTI, ileus and wound infection were noted and compared with each procedure. Time to recovery was also evaluated. Length of hospital stay associated with each route of hysterectomy was also compared. Mortality associated with any procedure was recorded.

Statistical Analysis-
The data of the present study were fed into the computer and after its proper validation, checking for error, coding and decoding were compiled and analysed with the help of SPSS 11.5 software for windows. Appropriate univariate and bivariate analysis and ANOVA (analysis of variance) for more than two means were carried out using t-test were calculated and tested. All means are expressed as mean + standard deviation. The critical values for the significance of the results were considered at 0.05 levels.

Results
This prospective study was carried out in the department of Obstetrics and Gynaecology, N.S.C.B. medical College, There are 4 main indications encountered in the cases. Prolapes was mainly operated by vaginal route. 2 cases of DUB operated by vaginal route (non descent vaginal hysterectomy). Main indication for TAH was fibroid, DUB and PID. 2 cases of III 0 descent and 11cases of II 0 descent were operated by TAH (prolapse with Adnexal mass and Tubo-ovarian mass) Indication for LAVH was fibroid, PID, DUB & II 0 descent. There is no well defined indication for LAVH in the study. In all three groups, maximum cases start ambulation on day 3 and 4.P> 0.05 (not significant)      Most of the cases in the study were from rural areas (as maximum cases in our medical college come from rural areas which comes under the Jabalpur division). Mean parity was 3.78 ± 1.61 SD and mean BMI was 20.59 ± 2.1 SD and did not differ between the three groups. Nulliparous patients were statistically more frequent in the TAH group as compared to vaginal and LAVH (P<0.05). There is no difference in the socioeconomic status between the three groups. (P>0.05, not significant). 53.3% at women were post-menopausal, of which 47.6% were from vaginal group (as prolapse is precipitated after menopause). Mean Hb level in the study was 9.23gm% ± 1.26 SD and did not differ between the three groups (P>0.05, not significant) [5,6].
The indications of hysterectomy differed among groups. Four main indications in the cases coming to medical college: Fibroid, DUB, Genital prolapse and PID. Prolapse was a more frequent indication for vaginal hysterectomies; however, abdominal hysterectomies or Laparoscopically assisted vaginal hysterectomies were used in 16 out of the 76 cases that involved only prolapse. Fibroids were more frequently an indication for abdominal or laparoscopic assisted vaginal hysterectomy [7,8].
About 2 of the DUB cases operated by vaginal route (non-descent vaginal hysterectomy). Uterine size differed among the groups. It was significantly higher in the abdominal group than the vaginal group (P<0.05) and the LAVH group (P<0.05). No significant difference in the uterine size was found between LAVH and the vaginal group. Uterus was mobile in all cases at vaginal and LAVH, mobility restricted in 6 cases of TAH [9,10].
Co morbidity like anaemia, asthma and hypertension were more frequently associated with abdominal group. The frequencies of prior caesarean section and prior pelvic or bowel surgery differed among the groups. Patients operated on by vaginal route had no history of previous caesarean section. 5 [19,20].

Conclusion
There were 3 mortalities of cases of abdominal group. One death related to Intra-abdominal hemorrhage and one due to urinary tract injury. Another one died because of DIC and BT reaction. There was no mortality in LAVH and vaginal group. Study supports the view that, when possible, the vaginal route has significant advantages over LAVH and abdominal hysterectomy and should be the route of first choice. Hence there is a tremendous scope for improvement by careful pre operative assessment, meticulous surgical techniques and proper post operative care in order to reduce the complication rate.
Contribution by different author during study process and manuscript preparation: Actively participated in the study and made valuable contributions in finding references, convincing and counseling the patients, recording data and interpreting it by statistical analysis.
This study add to existing knowledge: Study support the view that, when possible, the vaginal route has significant advantages over LAV Hand abdominal hysterectomy and should be the route of first choice. Hence there is a tremendous scope for improvement by careful pre operative assessment, meticulous surgical techniques and proper post operative care in order to reduce the complication rate.
