Postoperative fistula of the abdominal wall after laparascopic cholecystectomy due to lost gallstones.

Abdominal fistula caused by cholesterol gallstones, which remained in the abdominal wall after laparascopic cholecystectomy: a laparascopic cholecystectomy was performed in a 60-years-old man who was diagnosed as acute necrosing cholecystitis due to cholecystolithiasis. After removal of the gallbladder using an Endocath some gallstones remained in the excision channel of the abdominal wall. Therefore, a fistula developed in the excision channel postoperatively. As the wound healing was disturbed an investigation of the abdominal wall was performed by ultrasound. In the former excision channel several small, oval, formations with high echogenicity and faint ultrasound shadows were detected, corresponding to additional gallstones. After excision of granulation tissue and removal of the cholesterol stones, complete healing of the fistula in the abdominal wall was achieved.

Use of an absorbable mesh to repair contaminated abdominal-wall defects.

When polypropylene mesh (Marlex) is used to repair contaminated abdominal-wall hernias, a high incidence of mesh-related chronic infection, drainage, erosion, and bleeding is noted. As an alternative to placing polypropylene mesh in a contaminated field, in the past 18 months we have used an absorbable polyglycolic acid mesh (Dexon) to repair contaminated abdominal-wall defects in eight patients--three with necrotizing abdominal-wall infections, one with an extensive electrical burn of the abdominal wall, three with infected polypropylene mesh from a previous repair, and one whose hernia was covered by a chronically infected scar. In seven of the eight cases, a single sheet of polyglycolic acid mesh was sewn to the fascial margins. In four cases, skin was closed over the mesh; wound packing and subsequent skin grafting were required in the other four. In follow-up studies that ranged from three to 18 months, six of the eight patients developed abdominal-wall hernias at the site of absorbable mesh placement. None of the patients required an abdominal binder. Postoperative hernia development is probable in patients whose defects are repaired with absorbable mesh. However, this complication is balanced against the more serious complications of fistula, bleeding, skin erosion, drainage, and chronic infection, which require removal of the more rigid nonabsorbable meshes in 50% to 90% of cases when the latter are placed under contaminated conditions. Placement of absorbable mesh for temporary abdominal-wall support until wound contamination resolves enhances the likelihood of subsequent successful placement of a permanent mesh.

Anterior abdominal wall reconstruction.

Reconstruction of the anterior abdominal wall is based on six basic principles. First, the anatomy of the abdominal wall and adjacent donor sites must be understood clearly. This includes a complete knowledge of the neurovascular anatomy and the arc of rotation of each subunit. The defect then has to be exposed completely before the definitive closure is attempted. Once the defect is established, abdominal domain is restored with some sort of support. The next phase of the repair involves reassigning local tissue to close the defect. Distant tissue then is imported from donor sites such as the thigh, if needed. Finally, the skin envelope is readjusted and closed. These principles help optimize function and restore form, hence achieving the best possible result.

Soft tissue tumors of the abdominal wall: analysis of disease patterns and treatment.

HYPOTHESIS: Abdominal wall tumors, though clinically similar, have varying degrees of biological behavior. DESIGN: Retrospective review of prospective databases. SETTING: Memorial Sloan-Kettering Cancer Center. PATIENTS: Eighty-five patients with abdominal wall soft tissue tumors. MAIN OUTCOME MEASURES: Primary endpoints included time to first local recurrence, distant metastases, and disease-related mortality. Survival analysis was performed by Kaplan-Meier method, and comparisons were made by log-rank analysis. RESULTS: Thirty-nine desmoids, 32 soft tissue sarcomas (STS), and 14 dermatofibrosarcoma protuberans (DFSP) underwent surgery directed at achieving margin-negative resection. Unlike DFSP, most STS (77%) and desmoids(87%) were deep lesions requiring full-thickness abdominal wall resection and mesh reconstruction. Median follow-up time was 53 months, 101 months, and 31 months, with 5-year local recurrence-free survival rates of 97%, 100%, and 75%, for desmoids, DFSP, and STS, respectively. Desmoid tumors resected with positive microscopic margins had higher local failure rates (68% [positive margin] vs 100% [negative margin] 5-yr local recurrence-free survival, P<.05). For STS, high grade, deep location, and size at or above 5 cm were adverse prognostic factors for disease-specific and distant recurrence-free survival (P<.05); patients experiencing local recurrence was associated with decreased 5-year relapse-free survival rates (87% [primary] vs 50% [local recurrence], P<.05). Characteristically, no DFSP or desmoid developed distant metastases. Soft tissue sarcomas had significantly lower relapse-free survival rates than DFSP or desmoids (P<.05). CONCLUSION: Abdominal wall tumors demonstrate a broad spectrum of biological behavior. Desmoids and DFSP are a local problem. High grade, size at or above 5 cm, and deep location predict distant failure and tumor-related mortality for patients with STS. Complete surgical resection is the recommended treatment approach to achieve local control. Stratification by prognostic factors will facilitate selection of patients with STS for adjuvant systemic therapies.

Abdominal wall abscesses in patients with Crohn's disease: clinical outcome.

Abdominal wall abscess due to Crohn's Disease used to be one of the definitive indications for operative treatment. The advent of interventional radiology, the accessibility to percutaneous drainage, and the availability of new medications raised the possibility of nonoperative treatment of this condition. The clinical presentation, treatment, and follow-up of 13 patients with abdominal wall abscesses secondary to Crohn's Disease were retrospectively reviewed. During a 10-year period (1993-2003), 13 patients with abdominal wall abscess were treated. Five patients had an anterolateral abdominal wall abscess and eight had a posterior abscess (psoas). In 11 patients, 17 drainage procedures were performed: 12 percutaneous and 5 operative. Despite initial adequate drainage and resolution of the abscess, all 13 patients eventually needed resection of the offending bowel segment, which was undertaken in 12 patients. The mean time between abscess presentation and definitive operation was 2 months. Percutaneous drainage is an attractive option in most cases of abdominal abscesses. However, in Crohn's Disease patients with an abdominal wall abscess, we found a high failure rate despite initial adequate drainage. We suggest that surgical resection of the diseased bowel segment should be the definitive therapy.

Transplantation of the abdominal wall.

BACKGROUND: Closure of the abdomen in patients undergoing intestinal transplantation can be extremely difficult, if not impossible. We describe our initial experience with abdominal wall allotransplantation to facilitate abdominal closure. METHODS: We undertook nine cadaveric abdominal wall composite allograft transplants in eight patients. The graft's blood supply was based on the inferior epigastric vessels left in continuity with the donor femoral and iliac vessels. Skin biopsies were undertaken randomly and when rejection was suspected. Vessel patency was monitored by doppler ultrasound. FINDINGS: Six patients have survived, five of whom have intact, viable abdominal wall grafts. Two patients have had a clinically mild episode of acute rejection of the skin of the abdominal wall that resolved with corticosteroid therapy. No clinically apparent graft-versus-host disease has been noted. INTERPRETATION: Transplantation of an abdominal wall composite allograft can facilitate reconstruction and closure of the abdominal compartment in intestinal transplant recipients with complex abdominal wall defects.

Carbon-fibre versus Marlex mesh in the repair of experimental abdominal wall defects in rats.

Large abdominal wall defects were created in Porton-Wistar rats and either left unrepaired (9 rats), or repaired with polypropylene (Marlex) mesh (11 rats), or with an open darn of filamentous carbon (11 rats). A further ten animals had a simple midline skin incision. At 5 months there were gross hernias in the unrepaired animals. Neither repair had resulted in gross recurrence although four of the carbon-repaired animals had bulges through the open weave. Tensiometry of the excised abdominal wall showed no difference in the strength of the two repairs. However, microscopy showed a striking difference-the Marlex had induced a chronic inflammatory response with disorganized collagen, whereas the carbon was not only well-tolerated but acted as a scaffold for well-organized and orientated collagen.

Updated algorithm for abdominal wall reconstruction.

Like any clinical regime, the algorithm for abdominal wall reconstruction requires routine updating as new options and techniques become available. Increased experience and understanding of new applications have allowed for improvements to the approach to complex abdominal wall defects. These improvements have increased efficiency and decreased risk, particularly in the area of staged reconstruction. Surgeons have continued to rely heavily on autologous reconstruction and local tissue advancement for long-term dynamic support. The current approach to abdominal wall reconstruction is based on understanding the literature, clinical experience, and the type of patients seen in practice. This article provides surgeons with the basic guidelines to follow when faced with complex abdominal wall defects and the tools necessary to solve these difficult problems in a responsible and reliable way.

Abdominal wall repair is delayed during hepatic regeneration.

BACKGROUND: Abdominal wall wound failure remains a common surgical problem. The signals that activate normal fibroplastic repair versus regeneration pathways are unknown. Transforming growth factor beta levels rise during incisional healing but fall during hepatic regeneration. Changes in the injured host cytokine milieu may therefore differentially effect abdominal wall repair versus hepatic regeneration. MATERIALS AND METHODS: Forty-eight rats were divided into four groups (n = 12). Groups 1-3 underwent sham celiotomy, 70% hepatectomy, or 80% enterectomy with anastamosis. Incisions from Group 4 were treated with either 1 microg of transforming growth factor beta(2) (TGF-beta(2)) or vehicle following hepatectomy. Isolated fascial and dermal incisions were harvested and tested for breaking strength on POD 7. Serum (TGF-beta(2)) and hepatocyte growth factor (HGF) levels were measured by ELISA. RESULTS: Recovery of incisional wound breaking strength was delayed following hepatectomy but not enterectomy (P<0.002). The inhibitory effect was observed in both the fascia and the dermis of the abdominal wall. TGF-beta(2) levels were depressed in hepatectomy animals on POD 7, while at the same time HGF levels were elevated. Exogenous TGF-beta(2) shifted the healing trajectory of deficient wounds back toward a control pattern. CONCLUSION: Abdominal wall fascial and dermal healing is delayed during hepatic regeneration. Elevated HGF and depressed TGF-beta(2) suggest a host mechanism that prioritizes hepatic parenchymal regeneration over fibroplastic repair (scar). Observations such as these are needed as therapeutic wound healing enters the clinical realm.

Staged reduction using a Silastic sac is the treatment of choice for large congenital abdominal wall defects.

Although the survival for infants with abdominal wall defects (AWD) has dramatically improved, agreement on the optimum surgical approach has not been reached. From October 1970 through March 1983, 31 neonates with gastroschisis and 14 neonates with omphalocele were treated. Reduction of the herniated viscera with primary fascial and skin closure was performed in 30% of the gastroschisis patients and 64% of the omphalocele patients. The remaining infants were managed by staged reduction of the herniated viscera using a Silastic sac. Overall, 27 of 45 patients (60%) were treated by staged reduction. Our procedure for staged reduction includes application of a Silastic sac as soon as the infant is stable. The herniated contents are reduced as rapidly as possible so that the prosthetic sacs can be removed within seven days. Abdominal wall stretching, "milking" of the intestinal contents into the stomach for decompression and a gastrostomy tube are avoided. The duration of hospitalization was not influenced by the method of abdominal wall closure in the gastroschisis infants. However, the hospitalization was approximately 10 days longer for those omphalocele patients managed by staged reduction. Complications which occurred in these patients include: respiratory distress (1); wound infection after removal of the Silastic sac (2); intestinal fistula (1); intestinal resection (3); intraabdominal sepsis (1); and incisional hernia (3). There was one death in the omphalocele group and three deaths in the gastroschisis group. Therefore, the overall survival for the 45 patients with AWD was 91%. Staged reduction of the herniated abdominal contents can be a safe, uncomplicated method of obtaining abdominal wall closure in neonates with AWD.

Abdominal wall repair using a biodegradable scaffold seeded with cells.

BACKGROUND/PURPOSE: The repair of large abdominal wall defects is still a challenge for pediatric surgeons. Synthetic materials, however, may lead to high complication rates. This study was aimed at applying tissue-engineering methods to abdominal wall repair. METHODS: 3T3 mouse fibroblasts were expanded in vitro. In the next step, a biodegradable material--polyglycolic acid (PGA)--was actively seeded with 10(7) cells/scm of PGA scaffold. Culture medium (Dulbecco's Modified Eagle's Medium with 10% fetal bovine serum) was changed every 6 hours after seeding cells on PGA fibers. Under general anaesthesia, C57BL/6J black mice underwent creation of a 2 x 3-cm abdominal wall defect (60%-70% of abdominal surface). The defect was repaired in the experimental group with the fibroblast-seeded PGA scaffold. In the first control group, the defect was covered with acellular PGA, and in the second control group, by skin closure. Animals were killed after 30 days to assess the histologic and gross findings. RESULTS: No abdominal hernia was found in animals repaired with cell-seeded and acellular scaffolds. All animals with skin closure died within 7 days. In every case, tissue-engineered construct was thicker then in controls. Histologic and gross examination revealed a good neovascularisation in tissue-engineered abdominal walls comparing to the acellular matrix. There was no intensive scar formation between abdominal wall and skin. CONCLUSIONS: Engineered soft tissue constructs can provide structural replacement of severe and large abdominal wall defects. Tissue engineering in the near future will possibly enter clinical practice.

Effect of relaparotomy through previously integrated polypropylene and polytetrafluoroethylene experimental implants in the abdominal wall.

BACKGROUND: The appearance of new pathologies affecting abdominal organs after implant of a prosthesis to repair an abdominal wall defect may necessitate reintervention. The aim of this study was to compare the behavior of two types of biomaterial widely used in clinical practice, polypropylene (PL) and polytetrafluoroethylene (ePTFE), after a second laparotomy involving the implant. The behavior, in terms of tensile resistance and integration with tissues, of intact prostheses was compared to that of prostheses subjected to opening and repair. METHODS: A defect (7x5 cm) involving all tissue layers was created in the anterior abdominal wall of 24 male New Zealand rabbits. These defects were repaired with a reticular, macroporous PL mesh (Marlex, Bard Card., Madrid, Spain) or a laminar, micro/macroporous ePTFE prosthesis (Mycro Mesh, W.L. Gore, Flagstaff, AZ) of similar size to the defect. Four study groups were established: Intact PL/Intact ePTFE (n = 6 each): animals implanted with a PL or ePTFE prosthesis and sacrificed 90 days after implant; Repaired PL/Repaired ePTFE (n = 6 each): animals implanted with a PL or ePTFE prosthesis subjected to midlongitudinal relaparotomy through the center of the prosthesis 90 days postimplant, followed by repair with continuous polypropylene 4/0 suture. Animals in repaired groups were sacrificed 90 days after the second intervention. Specimens comprised of prosthesis and neoformed tissue were subjected to light and scanning electron microscopy. In addition, 2 cm-wide strips, consisting of the prosthesis and anchorage tissue, were subjected to biomechanical analysis using an Instron tensiometer (Instron, Canton, MA). The results obtained were statistically compared using the Mann-Whitney U-test. RESULTS: The intact PL implants were fully infiltrated by dense, disorganized, well-vascularized scar tissue with fibers concentric to the mesh monofilaments. The appearance of the repaired PL prostheses was similar, with establishment of neoformed tissue in repaired areas of the prosthesis such that both cut edges of the prosthesis were joined together. In contrast, intact ePTFE prostheses were encapsulated by organized tissue with fibers running parallel to the surface of the biomaterial. Repaired ePTFE prostheses including sutured areas were similarly encapsulated. But the edges of the sutured middle area did not fuse. Tensile resistance values of intact and repaired PL prostheses were similar (intact, mean, 34.78 Newtons; repaired, mean, 34.74N, p>0.001). Tensile resistance values of intact ePTFE implants were significantly different to those of the repaired ePTFE prostheses (intact, mean, 22.64N; repaired, mean, 17.21N, p<0.001). Breakage of both types of PL specimen strips was restricted to recipient tissue while breakage of intact ePTFE specimens occurred in the areas of anchorage to the abdominal wall. Rupture of repaired ePTFE specimens took place in the sutured central areas of the prostheses. CONCLUSIONS: We conclude that relaparotomy through an existing PL prosthesis previously integrated with the abdominal wall does not affect the tissue integration process or the tensile resistance of the implant. When the relaparotomy involves an ePTFE prosthesis, however, although the repair process itself is unaffected, significant loss in tensile strength is incurred. In addition, relaparotomy through both types of biomaterial is likely to result in the neoformation of adhesions in the areas of the prosthesis subjected to opening and repair but, in general, the number of adhesions formed in the presence of intact or repaired polypropylene implants was larger than that observed with the use of ePTFE.

One-stage reconstruction of large midline abdominal wall defects using a composite free anterolateral thigh flap with vascularized fascia lata.

OBJECTIVE: Large midline abdominal wall defects are continuously a challenge for reconstructive surgeons. Adequate skin coverage and fascia repair of the abdominal wall is necessary for achieving acceptable results. The purpose of this paper is to present a new approach to abdominal wall reconstruction using a free vascularized composite anterolateral thigh (ALT) flap with fascia lata. METHODS: Seven patients with large full-thickness abdominal wall defects were successfully reconstructed by means of a composite ALT flap combined with vascularized fascia lata. The size of the skin islands ranged from 20 to 32 cm in length and 10 to 22 cm in width, and the vascularized fascia lata sheath measured 14 to 28 cm and 8 to 18 cm, respectively. Functional outcome of the abdominal wall strength and donor thigh morbidity were investigated by using a Cybex kinetic dynamometer. RESULTS: All flaps survived. No postoperative ventral hernia occurred except for one mild inguinal incision hernia. Subjectively there were no significant donor site problems. Objective assessment was performed in 4 patients 2 years postoperatively. In the reconstructed abdomen, isokinetic concentric and eccentric measurements of extension/flexion ratios of the abdominal wall strength showed no apparent decrease compared with other references. Functional evaluation of quadriceps femoris muscle contraction forces after free ALT composite flap harvest showed an averaged deficit of 30% as compared with the contralateral legs. However, no difficulties in daily ambulating were reported by the patients. CONCLUSION: The free composite ALT myocutaneous flap with vascularized fascia lata provides an alternative option for a stable repair in complex abdominal wall defects.

[Ultrasonic diagnosis of abnormalities of abdominal wall in fetuses].

Twelve cases of abnormal abdominal walls in fetuses are reported in this paper. Among them, there were 4 cases of umbilical hernia, 4 cases of a defective abdominal wall, 3 cases of diaphragmatic hernia and 1 case of a defective thoracic and abdominal wall. From the features of the sonographic picture, the reasons for misdiagnosis are discussed. From our analysis, the main points of differential diagnosis and the earliest time for making diagnosis are proposed. The diagnostic rate could be improved obviously by systemic and careful examination which is important for deciding the model and time of deliveries.

Abdominal wall partitioning (the accordion effect) for reconstruction of major defects: a retrospective review of 10 patients.

Ten patients underwent abdominal wall reconstruction using the technique of abdominal wall partitioning. All defects were closed in the midline by approximating fascia to fascia with the assistance of a general surgeon. One patient had skin grafted small bowel. Five patients had chronically infected mesh and previous failed attempts at repair. Four patients had large ventral hernias following gastric reduction operations and massive weight loss. No defect in any dimension was less than 20 cm. All patients had secure abdominal wall repair by reconstruction of a midline anchor for the abdominal wall musculature. One patient was lost to follow-up after 3 weeks. The average follow-up time for the remaining nine patients was 18.6 months (range, 6 months to 4.7 years). One patient required readmission to the hospital for management of a limited area of skin necrosis. Two patients had minor wound infections, and three patients had subcutaneous seromas, all of which were managed on an outpatient basis. One patient developed a 2 x 2-cm subxiphoid hernia recurrence. Technical details include subcutaneous undermining of the abdominal skin to the anterior axillary lines bilaterally, mobilization of the viscera to expose the white lines of Toldt bilaterally, and parallel, parasagittal, staggered releases of the transversalis fascia, transversalis muscle, external oblique fascia, external oblique muscle, and rectus fascia. These multiple releases allow expansion and translation of the abdominal wall by an accordion-like effect. This accordion-like effect allows closure of abdominal wall defects that are substantially larger than what can be closed with current techniques.

Efficacy of treating abdominal wall pain by local injection.

OBJECTIVE: When a patient's chief complaint is lower abdominal pain, but physical and ultrasonic examinations and laboratory tests show no evidence of any noticeable disease, physicians may make a wrong diagnosis, such as abdominal adhesion, chronic pelvic inflammatory disease, pelvic congestion and even psychosomatic disorders. In actuality, the pain may originate from the abdominal wall instead of the viscera. Local anesthetics coupled with steroid injections not only effectively alleviate the pain but also means that laparoscopy and medication can be avoided and is thereby worthy of wide use. Here, we present the results for the treatment of abdominal wall pain by local injection. MATERIALS AND METHODS: Between January 1994 and December 2005, we treated 211 abdominal wall pain patients. Diagnoses were based on the pressure of the abdominal wall tender point, which elicited sharp shooting pain during compression, and presence of positive Carnett's sign. After confirmation of the trigger point, a fine needle was used to inject a mixture of 0.5% bupivacaine 2 mL, 2% lidocaine 3 mL and 4 mg betamethasone 1 mL. The patients were examined on a weekly basis and underwent reinjection if symptoms recurred. RESULTS: There were 71 patients who were lost to or refused treatment or follow-up; the 140 remaining patients were evaluated. After trigger point injection in these patients, 95 (67.9%) reported no pain at all after treatment. Forty-five (32.1%) patients still had abdominal pain and required a second injection. A total of 133 (95%) patients showed complete pain resolution. After 3 months of follow-up, 115 (86.5%) patients remained free of abdominal pain. CONCLUSION: Local injection for selective abdominal wall pain patients produces significant pain relief. The diagnosis of abdominal wall pain is an important component in avoiding unnecessary operations in patients with abdominal pain.

Conservative treatment of giant abdominal wall hematoma.

A fifty-seven-year-old male patient on warfarin therapy presented to the emergency department with severe abdominal pain that had started after a cough episode and persisted for four days. Ultrasonography showed an extensive hematoma, 17x14x7 cm in size, but failed to determine whether it was located intra-abdominally or in the abdominal wall. Computed tomography confirmed the diagnosis of abdominal wall hematoma (25x21x10 cm). The patient was treated conservatively, and abdominal findings resolved progressively in three days. This case report illustrates that ultrasonography findings may sometimes be inconclusive and, in the early period, computed tomography may be required to confirm the diagnosis of abdominal wall hematomas. Giant abdominal wall hematomas can be successfully treated with conservative methods even physical findings of acute abdomen accompany the clinical picture. To our knowledge, this is the largest abdominal wall hematoma hitherto reported in the literature.

Porcine dermal collagen (Permacol) for abdominal wall reconstruction.

OBJECTIVE: A review of Eisenhower Army Medical Center's experience using Permacol (Tissue Science Laboratories, Covington, Georgia) for the repair of abdominal wall defects. METHODS: Retrospective review of medical records of patients undergoing abdominal wall reconstruction with Permacol. RESULTS: From July 30, 2003 to February 12, 2005, 9 patients underwent repair of complicated fascial defects with Permacol. Indications for surgery included reoperative incisional hernia repair after removal of a infected mesh (3 patients), reconstruction of a fascial defect after resection of an abdominal wall tumor (2 patients), incisional hernia repair in a patient with a previous abdominal wall infection after a primary incisional hernia repair (1 patient), incisional hernia repair in a patient with an ostomy and an open midline wound (1 patient), emergent repair of incisional hernia with strangulated bowel and multiple intra-abdominal abscesses (1 patient), and excision of infected mesh and drainage of intra-abdominal abscess with synchronous repair of the abdominal wall defect (1 patient). At a median follow-up of 18.2 months, 1 recurrent hernia existed after intentional removal of the Permacol. This patient developed an abdominal wall abscess 7 months after hernia repair secondary to erosion from a suture. Overall, 1 patient developed exposure of the Permacol after a skin dehiscence. The wound was treated with local wound care, and the Permacol was salvaged. Despite the presence of contamination (wound classification II, III, or IV) in 5 of 9 patients (56%), no infectious complications occurred. CONCLUSION: Complex reconstruction of the abdominal wall can be associated with a high complication rate. Placement of a permanent prosthetic mesh in a contaminated field is associated with a high rate of wound infections and subsequent mesh removal. Permacol becomes incorporated by tissue ingrowth and neovascularization. Permacol is a safe and acceptable alternative to prosthetic mesh in the repair of complicated abdominal wall defects.
