Objective: To examine the preliminary effect of laparoscopic extraperitoneal colostomy anterior to posterior sheath of rectus abdominis-transversus abdominis for the prevention of parastomal hernia after abdominoperineal resection for rectal cancer. Methods: This study is a prospective case series study. From June 2021 to June 2022, patients with low rectal cancer underwent laparoscopic abdominoperineal resection combined with extraperitoneal colostomy anterior to posterior sheath of rectus abdominis-transversus abdominis at the First Department of General Surgery, Shaanxi Provincial People's Hospital were enrolled. The clinical data and postoperative CT images of patients were collected to analyze the incidence of surgical complication and parastomal hernia. Results: Totally 6 cases of patient were enrolled, including 3 males and 3 females, aging 72.5 (19.5) years (M(IQR)) (range: 55 to 79 years). The operation time was 250 (48) minutes (range: 190 to 275 minutes), the stoma operation time was 27.5 (10.7) minutes (range: 21 to 37 minutes), the bleeding volume was 30 (35) ml (range: 15 to 80 ml). All patients were cured and discharged without surgery-related complications. The follow-up time was 136 (105) days (range: 98 to 279 days). After physical examination and abdominal CT follow-up, no parastomal hernia occurred in the 6 patients up to this article. Conclusions: A method of laparoscopic extraperitoneal colostomy anterior to posterior sheath of rectus abdominis-transversus abdominis is established. Permanent stoma can be completed with this method safely. It may have a preventive effect on the occurrence of parastomal hernia, which is worthy of further study.

OBJECTIVE: To explore the effectiveness of lobulated pedicled rectus abdominis myocutaneous flap to repair huge chest wall defect. METHODS: Between June 2021 and June 2022, 14 patients with huge chest wall defects were treated with radical resection of the lesion and lobulated pedicled rectus abdominis myocutaneous flap transplantation for reconstruction of chest wall defects. The patients included 5 males and 9 females with an average age of 44.2 years (range, 32-57 years). The size of skin and soft tissue defect ranged from 20 cm×16 cm to 22 cm×22 cm. The bilateral pedicled rectus abdominis myocutaneous flaps in size of 26 cm×8 cm to 35 cm×14 cm were prepaired and cut into two skin paddles with basically equal area according to the actual defect size of the chest wall. After the lobulated pedicled rectus abdominis myocutaneous flap was transferred to the defect, there were two reshaping methods. The first method was that the skin paddle at the lower position and opposite side was unchanged, and the skin paddle at the effected side was rotated by 90° (7 cases). The second method was that the two skin paddles were rotated 90° respectively (7 cases). The donor site was sutured directly. RESULTS: All 14 flaps survived successfully and the wound healed by first intention. The incisions at donor site healed by first intention. All patients were followed up 6-12 months (mean, 8.7 months). The appearance and texture of the flaps were satisfactory. Only linear scar was left at the donor site, and the appearance and activity of the abdominal wall were not affected. No local recurrence was found in all tumor patients, and distant metastasis occurred in 2 breast cancer patients (1 liver metastasis and 1 lung metastasis). CONCLUSION The lobulated pedicled rectus abdominis myocutaneous flap in repair of huge chest wall defect can ensure the safety of blood supply of the flap to the greatest extent, ensure the effective and full use of the flap tissue, and reduce postoperative complications.

Objective: To explore the method and plausibility of using free rectus abdominis flap (FRAF) to reconstruct the major and complex defects in the craniofacial regions after ablation of advanced sinonasal carcinoma. Methods: From 2007 to 2018 at No. 980 Hospital of Joint Logistic Supportive Force of People's Liberation Army of China, 13 patients with advanced carcinoma of nasal cavity and paranasal sinuses, including 11 males and 2 females, aged from 33 to 67 years, were treated with FRAF to repair the invasion of skull base, face and orbit. Based on adequate and meticulous preoperative evaluations on patients and tumors, complete resection of tumor bulks was performed. According to the sites, characters and extents of the defects, FRAF was introduced in different ways into reconstruction of major and complex defects in the craniofacial regions after resection of advanced sinonasal carcinomas, restoring the structure and contour of the craniofacial region. Results: Complete resection of tumors was achieved in all cases. For repairing the major and complex defects resulted from tumor ablation, FRAF graft was conducted in 13 patients with advanced sinonasal carcinomas. The recipient vessels were facial artery and vein in 9 cases, superficial temporal artery and vein in 4 cases. Vascular bridging with the external jugular vein was carried out in 2 cases who underwent submandibular neck dissections, in which facial artery and vein were used as recipient vessels. Free fibular flap was used along with FRAF in a case undergone bilateral maxillectomy. Pedicled galea capitis and periosteal flap were applied simultaneously in 3 cases with dura defects at the skullbase resulted from tumor resection. All flaps used in 13 cases survived uneventfully without major complications, with successful repair of defects, reconstruction of structures and restoration of contour of craniofacial regions. Conclusion: With adequate evaluation of resectability of tumors as well as nature and extent of defects after tumor removal, FRAF transplantation is an ideal method and strategy of choice for reconstructing the major and complex defects in craniofacial regions resulted from tumor ablation of advanced sinonasal carcinomas.

BACKGROUND: Bilateral microsurgical autologous reconstruction is known to increase operating time, costs, and complications compared to unilateral procedures. This study aimed to determine whether a unilateral pedicled transverse rectus abdominis myocutaneous (TRAM) flap and a unilateral deep inferior epigastric artery perforator (DIEP) free flap could be a feasible option for bilateral reconstruction in selected circumstances. METHODS: A retrospective chart review identified patients who underwent unilateral pedicled TRAM and unilateral DIEP reconstruction for bilateral breast reconstruction between 2011 and 2014. Surgical outcomes, complications, and aesthetic scale questionnaire responses were evaluated. RESULTS: Fourteen patients were included in this study. Ten patients received bilateral immediate reconstruction, while four patients with a previous history of mastectomy underwent unilateral immediate reconstruction and contralateral delayed reconstruction. All flaps survived without any major complications. A case of nipple-areolar skin necrosis on the pedicled TRAM side and a case of mild abdominal bulging at the free DIEP donor site were reported. There was no partial flap necrosis or palpable fat necrosis. On the aesthetic outcome scale, the free DIEP flaps scored significantly higher than did the pedicled TRAM flaps for overall shape, the upper medial and lower lateral quadrant, and the lateral chest wall. CONCLUSIONS: Our findings suggest that a unilateral pedicled TRAM flap together with a unilateral free DIEP flap could be performed as a bridging surgical option as institutions move toward bilateral free-flap reconstructions, as a way to reduce operating time and the risk of microsurgery-related complications with acceptable donor site morbidity and aesthetic outcomes.

PURPOSE: The creation of the nipple-areola complex is the final stage in breast reconstruction and highly affects patient satisfaction. The neo-nipple is well known to shrink over time, particularly in the nipple projection. Currently, no reconstruction technique is clearly superior in terms of nipple size maintenance. We evaluated nipple size changes among several methods of breast mound reconstruction. METHODS: Seventy-eight patients received nipple-areola complex reconstruction secondarily after breast reconstruction. C-V flap nipple reconstructions were performed using a free transverse rectus abdominis myocutaneous (TRAM) flap in 25 cases (TRAM group), a latissimus dorsi (LD) myocutaneous flap in 27 cases (LD group), and an implant in 26 cases (implant group). The circumference and projection of the neo-nipple were measured using a flexible ruler, immediately after reconstruction and average 10 months after surgery. RESULTS: The overall circumference and projection at the final measurement were 91.43% ± 7.11% and 62.16% ± 21.55%, respectively, of immediate postoperative values. The change in circumference did not significantly differ among the 3 groups. In contrast, the change in projection was significantly worse in implant group compared to that in TRAM and LD groups. In addition, among the patients in implant group, greater inflation was significantly associated with greater decrease in the nipple projection. CONCLUSION: Breast mound reconstruction with autologous musculocutaneous flap techniques achieves better long-term maintenance of the neo-nipple projection compared to that achieved with expanded tissue and implantation. Considering the prospective loss of long-term nipple dimension, the preoperative design should be oversized in accordance with its origin in mound reconstruction.

BACKGROUND: Topical hemostatic agents are used when ligation, electrocauterization, or other conventional hemostatic methods are impractical. Because a hemostatic agent is a foreign body, it can cause foreign body reactions, inflammation, and infections that can interfere with the wound healing process. Therefore, we should select hemostatic agents after considering their effects on wound healing. Here, we compared the effects of hemostatic agents on wound healing in a rectus abdominis muscle defect in rats. METHODS: Twelve Sprague Dawley rats were subjected to creation of a 6 × 6 mm defect in the rectus abdominis muscle and divided into four groups: control group; group A, Tachosil fibrin sealant patch; group B, Surgicel Fibrillar oxidized regenerated cellulose; and group C, Surgicel Snow oxidized regenerated cellulose. For the histologic analysis, biopsies were performed on the 3rd, 7th, and 27th days. RESULTS: The foreign body reaction was the weakest in group A and most significant in group C. The inflammatory cell infiltration was the weakest in group A and similar in groups B and C. Muscle regeneration differed among periods. The rats in group A were the most active initially, while those in group C showed prolonged activity. CONCLUSION: Tachosil and Surgicel administration increased inflammation via foreign body reactions, but the overall wound healing process was not significantly affected. The increased inflammation in the Surgicel groups was due to a low pH. We recommend using Tachosil, because it results in less intense foreign body reactions than Surgicel and faster wound healing due to the fibrin action.

BACKGROUND: Thoracodorsal vessels (TDVs) and internal mammary vessels (IMVs) have both been widely employed as recipient vessels for use in free muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flaps. However, whether TDVs or IMVs are preferable as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap remains controversial. The purpose of this study was to compare the clinical outcomes when TDVs were used as recipient vessels to those obtained when IMVs were used as recipient vessels for autologous breast reconstruction with a free MS-TRAM flap. METHODS: A retrospective matched-cohort study was performed. We retrospectively reviewed data collected from patients who underwent a free MS-TRAM flap for autologous breast reconstructions after mastectomy between March 2003 and June 2013. After a one-to-one matching using age, 100 autologous breast reconstructions were selected in this study. Of the 100 breast reconstructions, 50 flaps were anastomosed to TDVs and 50 to IMVs. Patient demographics and clinical outcomes including operation time, length of hospital stay, postoperative complications, and aesthetic score were compared between the two groups. RESULTS: No statistically significant differences were found between the two groups in patient demographics and clinical outcomes, including the complication rates and aesthetic scores. There were no major complications such as total or partial flap loss in either group. CONCLUSIONS: The results of our study demonstrate that both TDVs and IMVs were safe and efficient as recipient vessels in terms of the complication rates and aesthetic outcomes.
