Abstract Background A relationship between obesity and adverse outcomes in patients with post-sternotomy wounds undergoing pedicle flap reconstruction is not well-documented. In this study, we present a single-centre retrospective case series analysis of early postoperative outcomes of patients with infected post-sternotomy wounds undergoing pedicle flap reconstruction. We also propose a management algorithm for such patients, based on BMI and wound width. Methods We retrospectively analyzed all patients, who underwent pedicle flap reconstruction for major sternal wound infections after sternotomy for cardiac surgery in a tertiary hospital in Germany during a 5-year period. Exclusion criteria included patients younger than 18 years of age and patients with BMI < 18.5 kg/m2. Patients were divided into 2 groups according to BMI: normal-weight (NW; BMI < 25 kg/m2) and overweight/obese (OB/OW; BMI > 25 kg/m2). Both groups were compared in terms of preoperative parameters and early postoperative outcomes. Preoperative parameters included demographics, wound bacteria and comorbidities. Postoperative outcomes included duration of surgery time (from incision to skin closure), transfusion requirement (during surgery and entire hospital stay), onset of flap and donor-site complications, length of stay and 30-day mortality. We employed the two-tailed t-test to compare continuous variables and the two-sided Fischer’s exact test to compare categorical variables. Statistical significance was set at p < 0.05. Results The total sample consisted of 48 patients. Overall mean BMI was 28.4 (6.1) kg/m2. Mean age was 67 (12) years. The study group consisted of 28 patients with BMI > 25 kg/m2, who were compared with 20 normal-weight patients. There was a significant difference amongst both groups regarding duration of surgery (120 vs. 174 min, p < 0.05). Donor-site complications requiring intervention were observed in 30% of patients in both groups. Flap-related complications were recorded in 16 (57%) cases in the study group and 7 cases in the control group (35%, p = 0.15). Conclusions We conclude that wound width and BMI can aid the decision-making process for patients with infected sternal wounds after cardiac surgery requiring pedicle flap reconstruction. However, in our case series analysis, OB/OW patients were not found to be at statistically significantly increased risk for worse postoperative outcomes, but were associated with a longer duration of surgery.

The interest of surgeons in the greater omentum is associated with a unique combination of such functions as plasticity, immune defense, barrier, hormonal, angiogenesis and regeneration for adjacent tissues, reabsorption, hemostatic, thermoregulation. The purpose of this review was to track the historically changing position of operations with the use of the greater omentum in abdominal, thoracic surgery, reconstructive plastic surgery, analyze the aspects of the use and controversial issues of omentization of the anastomoses line and omentoplasty in modern conditions, as well as highlight promising directions for the use of the greater omentum in medicine. in the sources of domestic and foreign databases until July 2021. Information about the negative consequences of omentectomy is given – a decrease in local and general immunoresistance, the development of adhesive disease, an increase in the number of postoperative purulent-inflammatory complications. It is useful for the surgeon to use a large omentum in non-standard and technically difficult cases. Situations are described in which a radical attitude to the greater omentum is justified – torsion of the omentum strand, metastasis, adhesions, omentitis, entrapment in hernias, complications from the pedicle flap. Analysis of the literature revealed ambiguous results of omentization and omentoplasty, which indicates the need for randomized studies in this area, the development of clinical recommendations for these operations with a description of clear indications and methods of carrying out.

We described a reconstruction method for restoring hook grip function of the fingers in patients with total brachial plexus injury. The paralysed latissimus dorsi muscle was transferred to the upper limb as a pedicle flap and sutured to the flexor digitorum profundus tendons. The muscle was then reanimated with two intercostal donor nerves to the thoraco-dorsal nerve. Fourteen young adult patients (mean 23 years, range 17 to 32 years) with traumatic brachial plexus injury who underwent reconstruction using this technique from 2000 to 2019. After mean follow-up of 65 months (range 20 to 170), finger flexion of strength greater than or equal to M3 was achieved in 10 of the 14 patients. The mean weight that could be lifted using a hook grip was 2.6 kg, and that which could be lifted with both hands was 4.1 kg. The intercostal nerve-innervated latissimus dorsi muscle transfer can provide useful hook grip hand function without the need to sacrifice donor vessels or healthy muscles. Level of evidence: IV

Aim: This study aimed to evaluate the clinical outcomes, shoulder muscle strength, and donor site morbidity following the free latissimus dorsi (LD) muscle pedicle flap transfer. Materials: Patients with free LD muscle pedicle flap reconstructions and with asymptomatic shoulders (affected and contralateral side) were included. The follow-up duration was 12 months. The combined shoulder range of motion (ROM), Constant–Murley shoulder (CMS), and quick disabilities of the arm, shoulder, and hand (QuickDASH) scores were measured preoperatively and at 1 year postoperatively. The ratio of the isokinetic muscle strength and total work was measured with an isokinetic dynamometer (Cybex 350®) both preoperatively and at sixth month postoperatively. Results: Twenty patients with a mean age of 37.06 ± 9.74 years and a mean body mass index of 23.49 ± 8.6 kg/m2 were included. The difference in shoulder ROM and CMS and increase in QuickDASH were not significant at the first postoperative year. The peak torque and total work performed decreased by 13%–16% for the adductor and extensor functions at the six month postoperatively, and these differences were significant. Although the adductor peak torque was significantly lower in the postoperative test of the operated side, no significant difference was found between the operated and unaffected shoulder peak torque values. Moreover, no significant difference was noted between the operated and unaffected shoulders in all isokinetic tests pre- and postoperatively. Conclusion: The free LD muscle pedicle flap harvest did not decrease function and ROM at the first postoperative year. The muscle strength and total work of shoulders after the LD muscle transfer returned to the preoperative condition at the sixth month, except adductor and extensor muscle strengths. However, adductor and extensor muscle strengths of the operated shoulders were not significantly different postoperatively. Level of Evidence: Level IV, Diagnostic study

Abstract Introduction Up to the second half of the twentieth century, pedicled flaps marked the gold standard in reconstructive surgery. Followed by the introduction of microsurgical techniques, these flaps were increasingly abandoned. We conducted a retrospective study to determine the value of two-stage pedicle flaps in modern maxillofacial reconstruction. Material & Methods A chart review from October 2017 to November 2020 was performed to identify patients who were treated by a two-stage pedicle flap in our Department of Oral and Maxillofacial Surgery. Results A total of 31 patients, 17 female and 14 males received 36 two-stage pedicle flaps. All patients were in noticeably impaired health condition with a majority of ASA-score 3. The defect location mainly contained extraoral resections (58.3%). A variety of flaps were harvested consisting of buccal flaps, Abbe flaps, forehead flaps, deltopectoral flaps, nasolabial flaps, and a tubed flap. Discussion The study outlines two indications for the use of two-stage pedicle flaps. Firstly, as a back-up strategy in heavily pre-treated wound beds and secondly in an almost contrarily indication as a first-choice reconstructive option of the facial skin in esthetic demanding cases. Conclusion The timesaving and straight forward surgical approach as well as their low postsurgical complications and strong long-time success rates secure the two-stage pedicle flap a justified niche role in times of microsurgical maxillofacial reconstruction.
