To evaluate whether the technique to open the abdomen might influence the operative time and the maternal and neonatal outcome.
                All consecutive women who underwent a cesarean section at a gestational age greater than or equal to 32 weeks were randomly allocated to have either the Joel-Cohen or the Pfannenstiel incision. Exclusion criteria were two or more previous cesarean sections and previous longitudinal abdominal incision. During the study period 366 patients underwent a cesarean delivery. Of these patients, 56 did not meet the inclusion criteria. The remaining patients were allocated to the Joel-Cohen (n = 152) group and to the Pfannenstiel (n = 158) group. Extraction time was defined as the time interval from skin incision to the clamping of the umbilical cord.
                The total operative time was similar in both groups [Joel-Cohen 32 min (12-60) vs. Pfannenstiel 33 min (18-70)]. The extraction time was shorter in the Joel-Cohen group than in the Pfannenstiel group [190 s (60-600) vs. 240 s (50-600), p = 0.05]. This remained statistically significant after adjustment for confounding variables (Hazard = 1.26, p = 0.05). No difference was found between groups in terms of intraoperative and postoperative complications. No difference was found in the neonatal neurodevelopmental assessment at 6 months of age in relation to the abdominal incision performed.
                The Joel-Cohen method of opening the abdomen at cesarean delivery is faster then the Pfannenstiel technique at delivering the fetus. However, considering the absence of benefits to the mother and the fetus there is no clear indication for performing a Joel-Cohen incision. To compare an innovative cesarean section based on Joel-Cohen incision with the traditional Pfannenstiel technique in terms of operative data and post-operative recovery.
                Out of 158 randomized patients, 83 patients underwent the innovative cesarean section (Joel-Cohen incision, one-layer locked uterine suture, no peritoneization) and 75 the traditional operative approach (Pfannenstiel incision, double layer closure of the uterus, visceral and parietal peritoneization). Operative data and post-operative morbidity were compared; sample size was calculated to detect a 13% difference in the occurrence of post-operative fever with a statistical power of 80%.
                Post-operative fever was not different in the two groups. Total operating time was shorter with the innovative technique: 31.6 +/-1.38 min vs. 44.4+/-1.44 (P=0.0001) and fewer sutures were used: 3.6+/-0.13 vs. 6+/-0.13 (P=0.001). Patients operated by the new technique began moving sooner and intestinal function restarted earlier.
                The proposed technique made for shorter operating times and faster recovery but no decrease in puerperal morbidity. To investigate whether a series of changes in the current caesarean section operative routine, based on new knowledge, would be beneficial.
                A prospective controlled trial.
                Labour ward with approximately 3000 deliveries annually in a suburban area of Gothenburg, Sweden.
                Seventy-two pregnant women scheduled for delivery by caesarean section were randomised to either modified Joel-Cohen technique (n = 36) or Pfannenstiel technique (n = 36).
                Blood loss during surgery and operating time.
                The median estimated intra-operative blood loss was 250 mL in the modified Joel-Cohen group and 400 mL in the Pfannenstiel group (P = 0.026). The proportion of women with > or = 300 mL was 16/36 in the modified Joel-Cohen group vs 28/36 in the Pfannenstiel group (OR 0.229, 95% CI 0.082-0.637). Median operating time was 20 min in the modified Joel-Cohen group compared with 28 min in the Pfannenstiel group (P < 0.001). The proportion of women with > or = 25 min was 1/36 in the modified Joel-Cohen group vs 33/36 in the Pfannenstiel group (OR 0.003, 95% CI 0.000-0.026).
                We conclude that the modified Joel-Cohen technique of caesarean delivery reduced intraoperative blood loss and operating time compared with the Pfannenstiel technique. The aim of the study was to evaluate the outcome of two different methods of cesarean section (CS).
                The study was designed as a prospective, randomized, controlled trial.
                All CS were performed at the University Hospital in Uppsala, Sweden.
                Fifty women admitted to hospital for a first elective CS were consecutively included in the study. They were randomly allocated to two groups.
                One group was operated on by the Misgav Ladach method for CS and the other group by the Pfannenstiel method. All operations were performed by the same surgeon.
                Duration of operation, amount of bleeding, analgesics required, scar appearance and length of hospitalization.
                Operating time was significantly different between the two methods, with an average of 12.5 minutes with the Misgav Ladach method and 26 minutes with the Pfannenstiel method (p<0.001). The amount of blood loss differed significantly, with 448 ml and 608 ml respectively (p=0.017). Significantly less analgesic injections and tablets (p=0.004) were needed after the Misgav Ladach method.
                The Misgav Ladach method of CS has advantages over the Pfannenstiel method by being significantly quicker to perform, with a reduced amount of bleeding and diminished postoperative pain. The women were satisfied with the appearance of their scars. In this study no negative effects of the new operation technique were discovered. Modifications to the classic cesarean section technique described by Pfannenstiel and Kerr have been proposed in the last few years. The objective of this trial was to compare intraoperative and short-term postoperative outcomes between the Pfannenstiel-Kerr and the modified Misgav-Ladach (MML) techniques for cesarean section.
                This prospective randomized trial involved 162 patients undergoing transverse lower uterine segment cesarean section. Patients were allocated to one of the two arms: 88 to the MML technique and 74 to the Pfannenstiel-Kerr technique. Main outcome measures were defined as the duration of surgery, analgesic requirements, and bowel restitution by the second postoperative day. Additional outcomes evaluated were febrile morbidity, postoperative antibiotic use, postpartum endometritis, and wound complications. Student's t, Mann-Whitney, and Chi-square tests were used for statistical analysis of the results, and a p < 0.05 was considered as the probability level reflecting significant differences.
                No differences between groups were noted in the incidence of analgesic requirements, bowel restitution by the second postoperative day, febrile morbidity, antibiotic requirements, endometritis, or wound complications. The MML technique took on average 12 min less to complete (p = 0.001).
                The MML technique is faster to perform and similar in terms of febrile morbidity, time to bowel restitution, or need for postoperative medications. It is likely to be more cost-effective. The Joel-Cohen incision followed by nonclosure of pelvic and parietal peritoneum has been advocated as an alternative method to the Pfannenstiel incision with peritonealization at cesarean section. A randomized trial was designed to compare intra- and postoperative morbidity between the two techniques. Women to undergo a cesarean section were randomly allocated to have either the Joel-Cohen incision with the parietal and pelvic peritoneum left open (group 1) or to have the Pfannenstiel incision with both peritoneal layers sutured (group 2). The myometrium was closed with 1-0 polyglactin 910 suture using a continuous single-layer nonlocking technique. Patients in group 2 had the peritoneum approximated with 2-0 polyglactin 910 suture. The fascia was sutured with continuous 1-0 polyglactin 910 suture in all cases. Opening time was defined as the interval from skin incision to the opening of the uterine cavity. Febrile morbidity was defined as a temperature > or =38 degrees C on two occasions 4 hours (hr) apart excluding the first postoperative day. Endometritis was defined as postpartum temperature > or =38 degrees C on two occasions 4 hr apart, with uterine tenderness and/or foul-smelling lochia. One hundred forty-nine and 150 patients were allocated to group 1 and to group 2, respectively. A shorter median (range) opening time [4 min (2-21) vs. 6 min (2-19), respectively, p < 0.01] and a shorter median (range) operative time [30 min (10-65) vs. 40 min (20-110), respectively, p < 0.01] were observed in group 1. No difference was found in terms of intraoperative complications, proportion of patients who required transfusion, endometritis, sepsis, febrile morbidity, and urinary tract infections. A higher rate of wound infections was found in group 2 than in group 1 [14 of 150 (9.3%) vs. 2 of 149 (1.3%), respectively, p < 0.01]. The Joel-Cohen incision without peritonealization resulted in a shorter opening and total operative time than the Pfannenstiel laparotomy with peritonealization. This was accomplished with a reduction of wound infections. Two alternative surgical techniques for elective laparoscopic cholecystectomy (LC), low-pressure insufflation of the peritoneal cavity and abdominal wall lifting (AWL), have been developed over time to minimize the disadvantages associated with CO2-elicited pneumoperitoneum. To the best of our knowledge, the 2 methods have seldom been compared as regards their relative advantages and disadvantages.
                Eighty patients scheduled for elective LC were randomized into either a low-pressure (8 mmHg) CO2 insufflation method (LPLC) group, or a gasless technique using a subcutaneous abdominal wall lifting device (GLC group). The duration of the surgical procedure, the surgical results including level of postoperative pain, and perioperative cardiopulmonary function changes experienced by the members of both groups were compared.
                Laparoscopic surgery was completed for all but 1 patient from each group due to an inadequate surgical-site exposure. There was no mortality for study participants, and no major complications were noted for members of either group. The LPLC group evidenced a shorter surgical duration as compared to the GLC group (77 +/- 28 minutes vs. 98 +/- 27 minutes, respectively; p < 0.01) and a lower incidence of postoperative shoulder pain (2/38 vs. 8/39, respectively; p < 0.05), although significant differences in intraoperative pulmonary function were noted (an increased PaCO2, Pet CO2 and peak-airway pressure and decreased arterial blood pH; p < 0.01) for the LPLC group compared to the GLC group.
                Both alternative methods for this type of surgery appeared feasible and safe for LC. Low-pressure CO2 pneumoperitoneum had a shorter surgical duration and less postoperative shoulder pain compared to the GLC technique, but did not feature any other advantage over the AWL technique with regard to impact on cardiopulmonary function. To compare active management of third stage of labour with 15-methyl prostaglandin F2alpha (PGF2alpha) and conventional management with methylergometrine as prophylaxis for postpartum hemorrhage, a randomised comparative study was carried out at Calcutta National Medical College and Hospital, Kolkata on 100 women. They were randomly allotted to one of the two groups. Group A included 50 women who received 15-methyl PGF2alpha (125 microg) intramusculary at the time of delivery of the anterior shoulder and group B included 50 women who underwent conventional management of the third stage of labour where methylergometrine 0.2 mg was given after delivery of placenta. Main outcome measured were duration of third stage, amount of bleeding and side-effects. The present study showed that there were significent reduction of the duration of third stage as well as reduction of amount of bleeding particularly when 125 microg of 15-methyl PGF2alpha was given intramuscularly at the time of delivery of the anterior shoulder in comparison to coventional method of management of third stage of labour with methylergometrine. Placental expulsion occurred within 4 minutes in group A and 16.5 minutes in group B. The amount of bleeding following delivery was 95.6 ml in average in group A and 249.6 ml in average in group B. 15-methyl PGF2alpha (125 microg) is certainly effective in prevention of postpartum haemorrhage particularly in developing country like India where this complication contributes a major factor for maternal mortality. Manual removal of placenta is performed in 1-3% of cases, and whilst a well established and relatively safe procedure, it is not without complications, which include infection, hemorrhage, uterine rupture, and occasional maternal death.
                A three-arm randomized controlled trial of 50 IU Syntocinon (in 30 ml N saline) versus 800 mcg misoprostol (in 30 ml N saline) versus 30 ml N saline alone (control), injected into the placental bed via the umbilical vein using the Pipingas method. A group sequential research model (triangular test: PEST4) was adopted to minimize the sample size, as retained placenta is a relatively uncommon condition.
                No significant difference in the rate of manual removal was observed between the control and Syntocinon groups. On triggering the automatic stopping rule for this arm of the trial all subsequent cases recruited were allocated to receive either Syntocinon or misoprostol. After a total of 54 cases a significant reduction in manual removal of placenta was observed in the misoprostol group, triggering the automatic stopping rule and terminating the trial.
                Misoprostol (800 mcg) dissolved in 30 ml N saline and administered by intraumbilical injection using the Pipingas technique significantly reduces the need for manual removal for retained adherent placenta, whereas Syntocinon has similar effectiveness to injection of N saline alone.
'Joel-Cohen based' methods have advantages compared to Pfannenstiel and to traditional (lower midline) CS techniques, which could translate to savings for the health system. However, these trials do not provide information on mortality and serious or long-term morbidity such as morbidly adherent placenta and scar rupture.
