Técnicas quirúrgicas en cesárea segmentaria. Revisión de evidencias

Aim: To know which have been the variations of the Pfannenstiel-Kerr technique and how they have influenced maternal morbidity and mortality. Methods: An electronic search was carried out in PubMed, Medline and Cochrane, of works in English and Spanish languages, regardless of the country of origin, preferably randomized and controlled between 2010 and 2020, on variations in the original surgical technique, with emphasis on the differences between the PfannenstielKerr and Miglav-Ladash techniques. Results: The more importants variations regarding morbidity and mortality were: 1. Preferring the transverse skin incision, especially the Joel Cohen type; 2. Lateral blunt dissection of the subcutaneous and cranio-caudal aponeurosis, after its incision; 3. Digital and lateral separation of the rectus abdominis muscles; 4. Digitally and laterally prolong the hysterotomy; 5. Uterine incision closure, without externalizing the uterus, in one or two suture planes, indifferently; 6. Do not suture the visceral and parietal peritoneum or approach the rectus abdominis; 7. Closure of the subcutaneous to separate points, if the thickness is greater than 2 cm. Conclusions: Modifications to the original technique achieved a statistically significant decrease in operative time, the number of sutures, the requirement for analgesics, blood loss, febrile morbidity, as well as operative wound infection and hospital stay.

DO TRANSVERSE SKIN INCISION & ADHESION AT POST CAESAREAN DELIVERY DELAY DELIVERY OF NEONATES & INCREASE MATERNAL MORBIDITY: A COHORT STUDY

Background: The most common major abdominal operation done on women is Caesarean section. Over the past century delivery by Caesarean section has been increased in both developed and developing countries. Various abdominal incisions have been used for Cesarean delivery. Today most of the caesarean section are performed with either a vertical infra umbilical midline incision [VIUI] or pfannenstiel incision. Both the skin incisions possess some benets and drawbacks. Methods: This study was a prospective cohort study conducted in the department of Gynaecology & Obstetrics, Burdwan Medical College & Hospital, Burdwan, West Bengal a tertiary teaching institute, from July, 2017 to November, 2018. 142 mothers were included in the study after informed consent from the patient about being a part of this study. Among them, 37 were with midline vertical skin incision, 51 were with transverse skin incision, and 54 were primigravida. Categorical variables are expressed as Number of patients and percentage of patients and compared across the groups using Pearson's Chi Square test for Independence of Attributes/ Fisher's Exact Test as appropriate. Results: 57.41% of primigravida are in 18 to 20 years age group, 42.59 % in 21-25 years, no women was over 25 years. women with previous vertical incision 27.03% have no adhesion, 59.46 % have mild adhesion, and 13.51% have severe adhesion. In women with previous transverse incision 21.57% have no adhesion, 47.06% have mild adhesion and 31.37%have severe adhesion. 34.7% adhesion are between uterus and bladder, 26.5% adhesion are between uterus and omentum, 20.4% adhesion are between uterus and abdominal wall, 12.2% adhesion between omentum and abdominal wall, 6.2% adhesion are in others organ Conclusions: There was signicant delay in delivery of neonates in post caesarean mothers with previous transverse skin incision than vertical incision. Previous transverse skin incision is associated with more severe adhesion than vertical skin incision

Maternal and neonatal outcomes in transverse and vertical skin incision for placenta previa

Background Placenta previa, a serious obstetric issue, should be managed by experienced teams. The safe and appropriate mode of delivery for placenta previa is by cesarean delivery. However, no studies were found comparing either maternal or neonatal outcomes for different skin incision in women with placenta previa. The aim of this study was to compare maternal and neonatal outcomes by skin incision types (transverse compared with vertical) in a large cohort of women with placenta previa who were undergoing cesarean delivery. Methods This was a retrospective cohort study carried out between January 2014 and June 2019. All pregnant women with placenta previa had confirmed by ultrasonologist before delivery and obstetrician at delivery. The primary outcome was the estimated blood loss during the surgery and within the first 24 hours postoperatively. Mean (standard deviation), median (interquartile range) or frequency (percentage) was reported to variables. Appropriate parametric and nonparametric tests were used to analyses. Results The study included 1098 complete records, 332 (30.24%) cases in the vertical skin incision group and 766 (69.76%) cases in the transverse skin incision group. Those with vertical incision showed a higher percentage of preterm delivery, anterior placenta, abnormally invasive placenta, and history of previous cesarean delivery, and a lower percentage of first pregnancy, in vitro fertilization, and emergency cesarean delivery. After controlling for confounding factors, higher incidence of post-partum hemorrhage (OR 5.47, 95% CI 3.84–7.79), maternal intensive care unit (OR 4.30, 95% CI 2.86–6.45), transfusion (OR 5.97, 95% CI 4.15–8.58), and 5-min APGAR< 7 (OR 9.03, 95% CI 1.83–44.49), a more estimated blood loss (β 601.85, 95%CI 458.78–744.91), and a longer length of hospital stay after delivery (β 0.54, 95%CI 0.23–0.86) were found in the vertical skin incision group. Conclusions Our data demonstrated that transverse skin incision group showed the better perinatal outcomes in women with placenta previa. Future collaborative studies are needed to be done by centers for placenta previa to have a better understanding of the characteristics and the outcomes of the disease in the choosing skin incision.

Maternal morbidity associated with skin incision type at cesarean delivery in obese patients: a systematic review

Aim: To describe the relationship between cesarean skin incision type and postoperative wound complications (WCs) in obese pregnant patients. Materials & methods: MEDLINE (PubMed and OVID), Embase, Scopus, Web of Science Core Collection, Cochrane Library and ClinicalTrials.gov databases were used for publication search. Selection criteria consisted of articles studying pregnant patients with BMI ≥30 kg/m2 undergoing cesarean delivery and assessing the effect of skin incision type on postoperative maternal outcomes. Results: Ten publications met criteria for a systematic review of a total of 2946 patients. The transverse skin incision was associated with a lower rate of WC compared with the vertical skin incision. The pooled risk ratio for WCs was 0.47 (95% CI: 0.37–0.58; p < 0.00001). Conclusion: Transverse skin incision may be preferable to vertical skin incision at cesarean delivery in pregnant patients with obesity as it may be associated with a lower rate of WCs.

Abnormally invasive placenta (AIP): pre-cesarean amnion drainage to facilitate exteriorization of the gravid uterus through a transverse skin incision

The number of pregnant women with abnormally invasive placenta (AIP) including clinical relevant placenta increta and percreta has markedly increased with a reported incidence of as high as one in 731, By 2020 in the United States, there will be an estimated 4504 new cases of AIP and 130 AIP-associated maternal deaths annually. The preoperative diagnosis and operative management of AIP is challenging. In a planned cesarean delivery, a vertical lower abdominal skin incision is widely used in order to have enough space to perform a hysterotomy above the cranial edge of the placenta to avoid significant fetal and/or maternal hemorrhage. We have used preoperative drainage of the amniotic fluid after epidural anesthesia and immediately before a planned cesarean delivery through a transverse skin incision in five patients with AIP of the anterior uterine wall. With less uterine volume, exteriorization of the gravid uterus is easily performed through a transverse laparotomy. The combination of amnion drainage, transverse laparotomy and exteriorization of the gravid uterus facilitates identification of the exact site of placental implantation, provides adequate space for performing fundal or high anterior or even posterior uterine wall incisions and to deliver the fetus safely while minimizing the risk of placental separation and subsequent uncontrolled blood loss. Furthermore, this technique provides the chance to leave the untouched placenta in situ or to remove the placenta in toto with a uterine wall segment.

Endoscopic Anatomy and Features of Anterior Cervical Foraminotomy by Destandau Technique

BACKGROUND: Minimally invasive spine surgery limits surgical trauma and avoids traditional open surgery so in the majority of cases, recovery is much quicker and patients have less pain after surgery.AIM: The authors describe an endoscopic approach to anterior cervical foraminotomy (ACF) by Destandau's method.MATERIAL AND METHODS: Anterior cervical foraminotomy by Destandau’s method is carried out under general anaesthesia. A 3 cm transverse skin incision is used just slightly past the anterior border of the sternocleidomastoid's muscle laterally. After exposing and dissecting superficial cervical fascia, platysma muscle, and deep cervical fascia, Endospine material designed by Destandau will be inserted. As from this moment, the procedure will continue using endoscopy.RESULTS: the Endoscopic approach to anterior cervical foraminotomy by Destandau's method offers a convenient access to the cervical foraminal stenosis with fewer complications and negligible morbidity and gives maximum exposure to discal space with the goal of minimising cutaneous incision.CONCLUSION: Contrary to the other minimally invasive approaches, the visual field in foraminotomy by Destandau technique is broad and depending on the workability of Endospine an adequate access to cervical disc is possible.
