Equal access to the abdominal aorta can be attained through midline and transverse abdominal incisions. The surgical literature suggests that transverse incisions cause less postoperative pain and morbidity. Fifty patients (10 females and 40 males, mean age 67 years) undergoing abdominal aortic surgery were randomised to a midline (n = 25) or transverse (n = 25) incision. All patients were evaluated preoperatively and postoperatively for seven days. Changes in pulmonary function (FVC and FEV1), time to open and close the incision, analgesia used (morphine mg/kg/h), clinical or X-ray evidence of chest infection, and the duration of ICU stay were recorded. In the transverse group there was a reduction in the incidence of chest complications (20% vs. 28%, p = ns) and these incisions took longer to open (13.9 +/- 4.6 vs. 9.9 +/- 5.1, p < 0.05), but overall there was no significant difference between any other parameter in the two groups. Our results show no statistically significant difference in morbidity or analgesia consumption following transverse or midline abdominal incisions and we conclude that the type of incision used can be left to the surgeon's preference. The influence of the type of abdominal incision on post-operative pain and pulmonary function was investigated in patients operated upon for a right-sided cancer of the large bowel.
                Fifty-three patients scheduled for a right hemicolectomy due to a right-sided colon cancer were randomized to a median vertical (M) or a transverse incision (T). Forty patients, 23 with a M and 17 with a T incision, completed the study and could be evaluated. Pain at rest and after physical activity was assessed with a visual analogue scale, and was also measured as reflected in the need for analgesics. Respiratory function was assessed with pre- and post-operative spirometry.
                Pain after activity was significantly less in patients with a T incision. This group also needed less analgesia. Vital capacity (VC) and forced expiratory volume in 1 s (FEV 1.0) were profoundly reduced after surgery in both groups of patients, but improvement of respiratory function was faster in patients with a transverse incision. No problem with access to the operative field was noted.
                We conclude that a transverse incision is preferable to a midline incision and should be used in right hemicolectomy. This abdominal incision reduces effort-induced pain and interferes less with post-operative pulmonary function, and may reduce the risk of pulmonary complications. Transverse and midline abdominal incisions are both commonly used for laparotomy to perform surgery on the pancreas and stomach, but comparative data are limited, especially from prospective randomized trials.
                During a predefined 2-year recruitment period, 94 patients undergoing an elective major laparotomy for disorders of the pancreas or stomach were enrolled in this study. The outcome measures were pulmonary function, incisional pain, and wound characteristics.
                The operation groups were equally divided according to the type of incision used. The patients who underwent transverse incision laparotomy had significantly better postoperative pulmonary function and significantly less postoperative incisional pain than those who underwent midline incision laparotomy (P < 0.05), but there were no differences in morbidity and the incidence of wound complications.
                Performing a transverse incision for surgery on the pancreas or stomach results in better postoperative pulmonary function and less incisional pain than a midline incision, without affecting postoperative morbidity. There are 2 main types of access for patients requiring major open, elective abdominal surgery: the midline or the transverse approach. The aim of this study is to compare both approaches by focusing on postoperative pain, complications, and frequency of incisional hernias.
                A recent Cochrane review suggested that transverse incisions may be less painful but incisional hernia rates do not differ.
                Randomized, patient- and observer-blinded, monocentric, equivalence clinical trial. Patients were scheduled for elective primary abdominal incisions. Composite primary end point measured 48 hours after surgery was the total amount of analgesics (piritramide) required in the last 24 hours and pain (Visual Analogue Scale). Secondary end points were early-onset and late complications. This study is registered in the ISRCTN registry and has the ID number ISRCTN60734227.
                Two hundred patients (101 midline and 99 transverse) were randomized. Both incision types resulted in similar amounts of required analgesics (95% confidence interval [-0.38; -0.33] was included in the equivalence level). For the Visual Analogue Scale, both the 95% and 90% CI (0-10) were neither within the equivalence levels nor were their differences significant at the 5% level. No relevant differences between midline and transverse incisions were observed for 30-day mortality (2 vs. 2, P = 0.99), mortality after one year (15 vs. 23, P = 0.15), pulmonary complications (13 vs. 17, P = 0.43), median length of hospital stay (11 vs. 12 days, P = 0.08), median time to tolerance of solid food (12 vs. 14 days, P = 0.30), and incisional hernias after one year (13 vs. 8, P = 0.48). More wound infections occurred in the transverse group (15 vs. 5, P = 0.02).
                The decision about the incision should be driven by surgeon preference with respect to the patient's disease and anatomy. A previous retrospective review of 2,006 emergency laparotomies had suggested that anesthesia and operative times could be reduced by using a continuous stitch closure for all layers of the incision. A prospective, randomized study was then implemented through use of odd/even digits in the last and next-to-last digits in the hospital number. Of 551 patients subjected to laparotomy because of abdominal trauma, no intraperitoneal injury was found in 212. There was no statistically significant difference in time expended or complications (wound or other, including pulmonary) on contrasting transverse (101) with vertical (111) incisions, or on comparing continuous (104) and interrupted (108) closure, with the exception of an average 26 minutes in time saved by a continuous suture (P = .02). Analysis of these same factors in 339 patients with trauma found at laparotomy could document no statistically significant difference. Such data support the use of a running suture for closure of the abdominal wall as a practical method to save anesthesia and operating time without increased risk of developing a wound or other postoperative complication. To determine whether a transverse incision is an alternative to a midline incision in terms of incisional hernia incidence, surgical site infection, postoperative pain, hospital stay and cosmetics in cholecystectomy. Incisional hernias after midline incision are commonly underestimated but probably complicate between 2 and 20% of all abdominal wall closures. The midline incision is the preferred incision for surgery of the upper abdomen despite evidence that alternatives, such as the lateral paramedian and transverse incision, exist and might reduce the rate of incisional hernia. A RCT was preformed in the pre-laparoscopic cholecystectomy era the data of which were never published.
                One hundred and fifty female patients were randomly allocated to cholecystectomy through midline or transverse incision. Early complications, the duration to discharge and the in-hospital use of analgesics was noted. Patients returned to the surgical outpatient clinic for evaluation of the cosmetic results of the scar and to evaluate possible complications such as fistula, wound dehiscence and incisional hernia after a minimum of 12 months follow-up.
                Two percent (1/60) of patients that had undergone the procedure through a transverse incision presented with an incisional hernia as opposed to 14% (9/63) of patients from the midline incision group (P = 0.017). Transverse incisions were found to be significantly shorter than midline incisions and associated with more pleasing appearance. More patients having undergone a midline incision, reported pain on day one, two and three postoperatively than patients from the transverse group. The use of analgesics did not differ between the two groups.
                In light of our results a transverse incision should, if possible, be considered as the preferred incision in acute and elective surgery of the upper abdomen when laparoscopic surgery is not an option. We performed a randomized study to evaluate the differences between upper midline incision and transverse incision for gastrectomy.
                Patients undergoing distal gastrectomy or total gastrectomy for gastric cancer were randomly allocated to have either an upper midline incision or a transverse incision. The times taken to open and close the abdominal cavity, the number of doses of postoperative analgesics, and the incidence of postoperative pneumonia, wound infection, and intestinal obstruction were compared between the patients having the two incisions.
                Times for both opening and closing the abdominal cavity were longer with a transverse incision, in both the distal gastrectomy group and total gastrectomy group. In the patients in whom continuous epidural analgesia was used postoperatively, the number of additional doses of analgesics was smaller in the transverse-incision group after distal gastrectomy. The incidence of postoperative pneumonia was lower in the transverse-incision group after distal gastrectomy. The number of patients with postoperative intestinal obstruction was smaller in the transverse-incision group than in the midline-incision group after distal gastrectomy. In contrast to distal gastrectomy, there was no significant difference in the number of doses of postoperative analgesics, incidence of postoperative pneumonia, or incidence of postoperative intestinal obstruction between the two study groups after total gastrectomy.
                A transverse incision for distal gastrectomy may be more beneficial than an upper midline incision in attenuating postoperative wound pain, decreasing the incidence of postoperative pneumonia, and preventing postoperative intestinal obstruction. Perioperative Thoracic epidural analgesia (TEA) is an important part of a multimodal approach to improve analgesia and patient outcome after cardiac and thoracic surgery. This is particularly important for obese patients undergoing off pump coronary artery bypass surgery (OPCAB). We conducted a randomized clinical trial at tertiary care cardiac institute to compare the effect of TEA and conventional opioid based analgesia on perioperative lung functions and pain scores in obese patients undergoing OPCAB. Sixty obese patients with body mass index >30 kg/m2 for elective OPCAB were randomized into two groups (n=30 each). Patients in both the groups received general anesthesia but in group 1, TEA was also administered. We performed spirometry as preoperative assessment and at six hours, 24 hours, second, third, fourth and fifth day after extubation, along with arterial blood gases analysis. Visual analogue scale at rest and on coughing was recorded to assess the degree of analgesia. The other parameters observed were: time to endotracheal extubation, oxygen withdrawal time and intensive care unit length of stay. On statistical analysis there was a significant difference in Vital Capacity at six hours, 24 hours, second and third day postextubation. Forced vital capacity and forced expiratory volume in one second followed the same pattern for first four postoperative days and peak expiratory flow rate remained statistically high till second postoperative day. ABG values and PaO2/FiO2 ratio were statistically higher in the study group up to five days. Visual analogue scale at rest and on coughing was significantly lower till fourth and third postoperative day respectively. Tracheal extubation time, oxygen withdrawal time and ICU stay were significantly less in group 1. The use of TEA resulted in better analgesia, early tracheal extubation and shorter ICU stay and should be considered for obese patients undergoing OPCAB. We assessed the efficacy and side effects of postoperative analgesia with three different pain regimens in 90 patients undergoing major abdominal surgery. The patients were randomly assigned to one of three groups: epidural morphine (EM) or sufentanil (ES), both combined with bupivacaine, or IM morphine (IM) at fixed intervals. Before incision, patients in the epidural groups received sufentanil or morphine in bupivacaine via a thoracic catheter, followed by a continuous infusion 1 h later. General anesthesia consisted of N2O/O2 and isoflurane for all groups. Patients in all groups received IV sufentanil as part of their anesthetic management. Patients in the IM group received IV sufentanil 1 microg/kg before incision, and patients in all groups received sufentanil 10 microg for inadequate analgesia. Postoperatively, the epidural or IM treatment was continued for > or =5 days. Postoperative analgesia at rest and during coughing and movement was significantly better in the epidural groups than in the IM group during the 5 consecutive days. There were no significant differences between the epidural groups. The incidence of most side effects was similar in all groups. We conclude that epidural analgesia provided better pain relief than IM analgesia, even if the latter was optimized by fixed-dose administration at fixed intervals and included adjustments on demand. Epidural sufentanil and morphine, both combined with bupivacaine, seemed to be equally effective with similar side effects.
                Postoperative analgesia with epidural sufentanil or morphine and bupivacaine after major abdominal surgery seemed to be better than the conventional method of IM morphine treatment, despite optimal administration, i.e., fixed doses at fixed intervals with regular adjustments. Analgesic efficacy and side effects of epidural sufentanil and morphine were similar.
The analgesia use and the pulmonary compromise may be reduced with a transverse/oblique incision but this does not seem to be significant clinically as pulmonary complication rates and recovery times were the same. The likelihood of wound dehiscence and rupture appears to be reduced with a transverse incision and a transverse incision may look better. The methodological and clinical diversity and the potential for bias also mean that the results in favour of a transverse/oblique incision (particularly with regard to analgesic use) should be treated with caution. The optimal incision for abdominal surgery still remains the preference of the surgeon.
