Project description:ObjectiveTo investigate the efficacy and clinical application advantage of omental tamponade with vascular pedicle combined with Laparoscopic fenestration for the treatment of diaphragmatic hepatic cyst.MethodsA total of 56 patients with diaphragmatic hepatic cysts underwent laparoscopic surgery in a single tertiary academic medical center from January 2010 to October 2020, including 21 patients (non-omental group) underwent laparoscopic fenestration of liver cysts, and 36 patients underwent laparoscopic liver cyst fenestration combined with vascular pedicle omentum tamponade (omental group). The general conditions and follow-up results of the two groups were compared and annalyzed.ResultsThe operation time of the omental group was longer than that of the non-omental group (P = 1.358E-4). There was no significant difference in postoperative complications, postoperative laboratory values and hospital costs (P>0.05). The length of hospital stay in omental group was shorter than that in non-omental group (P = 0.034). In the omental group, recurrence occurred in 1 of 35 patients (4.65%) who were followeded up 12 months after surgery. In the non-omental group, of the 21 patients followed, 3 patients (14.28%) recurred 6 months after surgery, and 8 patients (38.10%) recurred 12 months after surgery.ConclusionIt is an effective method to prevent the recurrence of diaphragmatic hepatic cyst after laparoscopic fenestration by packing the cyst with vascularized omentum.

Project description:BackgroundExtensive through-and-through oromandibular defects after advanced oral carcinoma excision pose a reconstructive challenge for the head and neck surgeon. These complex oromandibular wounds often involve the mandible, oral and/or aerodigestive mucosa, and the external skin. As a result, these defects are often not amenable to reconstruction with a single flap due to the volume of soft tissue needed and the three-dimensional reconstructive requirement. The use of two free flaps has often been suggested to overcome this reconstructive challenge. A simpler and less technically demanding way to deal with this may involve the use of a free flap in combination with a pedicled regional flap. We present our experience of the use of a simultaneous microvascular fibula free flap (FFF) with a pectoralis major myocutaneous flap (PMMC) for addressing these defects.MethodsA retrospective chart review was performed of patients treated with a FFF and PMMC combination for the reconstruction of oromandibular defects at the University of Mississippi Medical Center (Jackson, MS) between October 2013 and February 2016. A minimum follow-up of 12 months was required. Data collected included the extent and location of tumor involvement, size of the postablative defect, tumor histology, clinical and pathological staging, length of follow-up, functional outcomes, and associated complications.ResultsA total of three patients were identified to have been treated with the above technique. Defects repaired involved through-and-through mandibular defects with associated oral mucosa and external skin defects. In all cases, the FFF was used for restoring bony continuity with the skin paddle used to reconstruct the intraoral lining. The PMMC was used for reconstruction of the external skin defect and for providing soft tissue bulk. The average size of the fibula skin paddle used for intraoral reconstruction was 7.7 cm × 11.7 cm. The average size of the PMMC paddle was 7.3 × 9 cm. The mean follow-up was 21.7 months. Both the FFF and PMMC survived in all cases, although postoperative wound healing complications occurred in two of the three patients. There was one partial flap loss. Two patients regained good oral intake while one patient tolerated oral intake but was PEG tube-dependent.ConclusionsThe combination of pectoralis major myocutaneous flap and a vascularized free fibular flap is a viable option for the reconstruction of complex through-and-through oromandibular defects. This technique may be useful when a single microvascular free flap is not sufficient for reconstruction of such defects.

Project description:OBJECTIVE: Scapular free flap harvesting for oral cavity cancer reconstruction is an increasingly used and versatile option. We aim to describe the appearance of the scapula harvest site on chest radiograph and CT. METHODS: We retrospectively reviewed a surgical database of 82 patients who underwent scapular osteocutaneous flap harvesting for oral cavity cancer reconstruction and had imaging performed at our institution. We searched the picture archiving and communications system for all associated imaging. RESULTS: Characteristic radiographic appearance in the immediate post-operative period as well as in the remote post-operative period is described, including an upside-down V-shaped paraglenoid notch, rectangular (or triangular) lateral border defects and a sharply pointed inferior scapular body. Additionally, common CT appearances are discussed, including an abrupt gleno-scapular interval, an absent axillary rim bulge and a Z-shaped scapula. CONCLUSION: The altered appearance of the scapular defect following surgical harvest is easily recognised. Although the description of this defect may not alter management and may reasonably be omitted, a radiologist's comfort with these appearances may potentially enhance the understanding of patient management and recognition of superimposed complications, such as infection. ADVANCES IN KNOWLEDGE: Scapular osteocutaneous free flap reconstruction is an increasingly used technique after oral cavity surgery. Very few radiologists reported in our review the surgical scapular defects, and there is apparent ignorance of their appearance. We described characteristic radiographic and CT signs of scapular free flap harvesting to increase radiologists' familiarity with these defects, which may provide clinical information and possibly contribute to detection of complications.

Project description:Temporary or prolonged vascular spasm can be appreciated when perivascular dissection is performed for microvascular reconstruction. Due to a lack of reliable assessment modalities, the resolution of spasm at the periphery of perforators cannot be determined by naked eyes or surgical loupes. To address this conundrum, we aimed to observe the state of perforator vessel spasm after flap elevation using video-capillaroscopy. Between November 2021 and February 2022, seven free flaps were evaluated with video-capillaroscopy to determine the incidence of vasospasm in less than 1 mm-diameter perforators. The type of perforator spasm after flap elevation was divided into six types according to the video-capillaroscopy findings: type A, no spasm/decreased pulsation (S/DP); type B, S/DP with recovery within 5 minutes; type C, S/DP requiring papaverine hydrochloride spraying and hot water treatment (PHS+HWT) resulting in recovery within 5 minutes; type D, S/DP requiring PHS+HWT resulting in recovery within 10 minutes; type E, S/DP requiring PHS+HWT resulting in recovery within 15 minutes; and type F, S/DP with no recovery of pulsation even after PHS+HWT. Twenty-five perforators were evaluated, 3.57 perforators (range, 3-4) per flap. Using our classification for perforator vessel spasms on video-capillaroscopy, observations of five perforating branches were classified as type A, seven as type B, six as type C, five as type D, and two as type E. No type F spasm was observed. With video-capillaroscopy it is possible to confirm if blood flow deterioration occurs even in areas that are difficult to determine macroscopically. Video-capillaroscopy, a noninvasive imaging modality, is a useful alternative for the intraoperative evaluation of perforator flow and spasm.

Project description:Although the great toe plays important roles in walking, loading, and maintaining balance when compared with other toes, there are few reports on great toe reconstruction, including the reconstruction of distal phalanx. This report aims to describe the use of a superficial circumflex iliac artery perforator (SCIP)-osteocutaneous flap for reconstructing a complex tissue defect of the great toe. A 62-year-old man presented with a crush injury to the forefoot. Because the great toe was severely crushed, the defect distal to the proximal phalanx of the great toe was reconstructed using a SCIP-osteocutaneous flap. The immediate postoperative course was uneventful; however, surgical revision was necessary. Signs of osseous union could be observed on radiographic images taken 2 months after the initial surgery. Twenty-four months after surgery, the patient could freely walk without resorption of the transferred bone. We demonstrated that SCIP-osteocutaneous flaps may be promising free flaps in complex tissue defect reconstruction of the great toe.

Project description:Radioulnar synostosis is a rare complication after a forearm or elbow injury. The severity of initial trauma, associated head injury along with timing and the type of surgical treatment have been implicated in the formation of extra bone leading to synostosis. Surgical intervention is the standard treatment and is recommended after the maturation of synostotic bone. Surgery involves resection of the extra bone with or without tissue interposition. Materials used for interposition may include synthetic materials, allografts, and vascularized and non-vascularized autologous tissue superiority of one material over the other has not been demonstrated. Reported is a case of extensive soft-tissue defect and severe type II synostosis, with a relevant review of the literature.

Project description:Free flap reconstruction is the standard of care for extensive defects of the head and neck area. In this study, two types of free flaps, the antero-lateral thigh flap (ALT) and the vastus lateralis muscle flap, were compared. The primary endpoint was flap success, secondary endpoints were complication rates, hospitalization and surgery time. Cases with defect situations of the scalp and consecutive microvascular free flap reconstructions using either ALT flaps or vastus lateralis muscle flaps between 2014 and 2022 were retrospectively analyzed. Indications, perioperative handling and outcomes were compared. Twenty patients were included in the analysis. Ten patients (50%) received a free flap reconstruction using an ALT flap and ten patients (50%) received a vastus lateralis flap. A simultaneous two-team approach was possible in each case and the flap success rate was 100% with the need for one successful anastomosis revision. The mean defect size in our cohort was 147 ± 46 cm2. There were no significant differences in surgery time, duration of hospitalization or complication rate between both cohorts. Both free flaps, the ALT and the vastus lateralis flap, are suitable for the closure of large scalp defects. They provide high success rates, short surgery times without the need for patient repositioning and low donor-site morbidity. The vastus lateralis muscle flap bares the advantage of being perforator-independent and allows for the preparation of long vessels for anastomosis if needed while baring the disadvantage of a prolonged period of healing via granulation or the need for secondary surgery in terms of covering by split-thickness skin grafts which may interfere with necessary adjuvant treatment in oncological patients.

Project description:ObjectiveThe traditional lateral arm free flap (tLAFF) has the disadvantages of short vascular pedicle, small vascular diameter, and non-perforator flap. We used a new method to prepare modified LAFF (mLAFF) and evaluate its application value in the repair of oral and maxillofacial soft tissue defects.MethodsThe anatomical features of the flap were recorded and compared between the tLAFF group and the mLAFF group. All the flaps in the modified group were perforator flaps. Statistical analysis was performed on the data using ANOVA on SPSS 22.0 statistical software package.ResultsForty-five mLAFFs were prepared as eccentric design rotation repair perforated flap, or multi-lobed or chimeric perforator flaps. Compared with the tLAFF, the vascular pedicle length of the mLAFF was increased, and the outer diameter of the anastomosis was thickened. The damage to the donor site was less. The difference was statistically significant.ConclusionThe mLAFF can effectively lengthen the vascular pedicle length and increase the anastomosis diameter. Perforator LAFFs in the repair of oral and maxillofacial defects have good application value.

Project description:BackgroundDefects of the hand and foot often require an individualized reconstructive approach, due to their unique functional and aesthetic characteristics. Transferred tissues should be thin, pliable, and durable, with free fascial flaps meeting these requirements. This study aimed to evaluate the serratus fascia flap and the serratus carpaccio flap, which is a modification of the fascia flap, by including a thin muscle layer, with the goal of enhancing flap resilience and lowering morbidity rates.MethodsBetween January 2000 and December 2017, 31 patients underwent microsurgical reconstruction of the hand or foot either by serratus fascia flap (fascia group) or serratus carpaccio flap (carpaccio group). The serratus fascia flaps were mainly harvested between 2000 and 2012, and the serratus carpaccio flaps between 2013 and 2017. Patient records were reviewed retrospectively, regarding demographics, complications, overall flap survival, additional revision surgeries, and surgical outcome. Categorical variables were compared using Fisher's exact test and continuous data with the Mann-Whitney tests. Logistic regression was used to examine the correlation between comorbidities and postoperative complication rates. Differences were considered significant when p < 0.05.ResultsThe fascia group consisted of 17 patients and the carpaccio group of 14 patients. The average patient age in the fascia group was 39.2 ± 10.5 years, and it was 39.1 ± 14.7 years in the carpaccio group. Overall complication rates were significantly lower in the carpaccio group than in the fascia group (28.6% vs. 70.6%, p = 0.03). The rates of overall flap survival (85.7% in the carpaccio group vs. 74.5% in the fascia group, p = 0.66) and partial flap loss (14.3% in the carpaccio group vs. 47.1% in the fascia group, p = 0.07) did not differ significantly among both groups. One postoperative hematoma of the donor site requiring revision surgery was reported in the carpaccio group (7.1%, p = 0.45) while no donor-site morbidity was reported in the fascia group.ConclusionsOur findings indicate that the serratus carpaccio flap presents a promising alternative to the serratus fascia flap. This modification has proven to be effective in substantially reducing postoperative complications requiring additional surgical interventions. Therefore, the serratus carpaccio flap can be considered a dependable reconstructive option for addressing complex soft tissue defects of the hand and foot, with complication rates that are within an acceptable range.

Project description:Reconstructing extensive lower extremity soft tissue defects can present significant challenges for plastic surgeons. Determining a donor site for a flap of adequate surface area to cover critical structures while minimizing donor-site morbidity is difficult. We describe a novel windmill nonischemic free bilateral deep inferior epigastric perforator (DIEP) flap as a suitable option for the reconstruction of extensive lower extremity defects. Our patient is a 59-year-old man with a body mass index of 36 kg/m2 and a history of 23 kg weight loss after gastric sleeve placement. He presented to our service from the level 1 trauma center after sustaining a high-intensity crush injury to the right lower extremity and undergoing orthopedic reconstruction, which was complicated by wound dehiscence and hardware exposure. Following debridement, the defect measured 65 × 25 cm. A bilateral DIEP flap measuring 70 × 21 cm (among the largest by surface area described) was designed. The flap covered the defect fully, with perfusion obtained outside the zones of injury. A dual pedicle design was used to augment perfusion to the flap, with proximal and distal anastomoses in the lower extremity. Bilateral pedicles and 2 separate rotations across the recipient site allowed for reconstruction with no ischemia time. No complications occurred postoperatively or during the follow-up period (2.25 y). Combined or sequential flap transplantation is widely used in the reconstruction of extensive soft tissue defects. However, the windmill nonischemic free bilateral DIEP flap can cover a massive defect in a single stage with no ischemia time.
