Modifiable Preoperative Risk Factors to Mitigate Postoperative Site Infection Following Pediatric Gastrostomy.

PURPOSE: There are limited studies assessing modifiable preoperative risk factors for pediatric laparoscopic gastrostomy tubes (LGT) and percutaneous endoscopic gastrostomy (PEG) tubes. We sought to evaluate the effect of demographics and surgical/infectious history on the superficial infection rate following gastrostomy tube (GT) placement. METHODS: After IRB approval, we conducted a single-institution retrospective cohort study from 2015 to 2021 of pediatric patients undergoing LGT or PEG tube. The primary outcome was cellulitis or abscess formation within 30-days and 90-days postoperatively. Statistical analyses were performed with t-tests, Chi-squared, and logistic regression(p ≤ 0.05). RESULTS: There were 382 patients, with 181 (47%) LGT and 201 (53%) PEGs. LGT patients were younger (5.9 vs. 12.3 months, p < 0.001) and more likely to be admitted to the neonatal or cardiac intensive care unit prior to their GT. There were similar rates of prior surgical intervention (58% vs. 66%, p = 0.29) and previous infection (37% vs. 38%, p = 0.87) in both LGT and PEG patients. Within 30-days postoperatively, LGT patients had a higher superficial infection rate (12% vs. 6%, p = 0.04). On multivariate regression, Black race (Odds Ratio 0.10, p = 0.03) was protective and prior Staphylococcus colonization (OR 2.35, p = 0.04) increased the odds of infection. In those patients colonized with Staphylococcus, 21% developed a superficial site infection compared to 9% in those not colonized (p = 0.01). CONCLUSION: These data suggest prior Staphylococcus colonization is a significant risk factor for superficial infection following GT. Further work into preoperative decolonization strategies may provide an avenue to decrease the high infection rate in this common pediatric procedure. LEVEL OF EVIDENCE: Level III.

Lymphatic venous anastomosis and complex decongestive therapy for lymphoedema: randomized clinical trial.

BACKGROUND: Lymphatic venous anastomosis is associated with a low incidence of lower extremity lymphoedema-associated cellulitis; however, the exact relationship is unknown. This multicentre RCT evaluated the effect of lymphatic venous anastomosis on prevention of cellulitis. METHODS: Patients with secondary lower extremity lymphoedema who underwent at least 3 months of non-operative decongestive therapy were assigned randomly to lymphatic venous anastomosis or conservative therapy. The primary and secondary outcomes were cellulitis frequency, and assessments of circumference, hardness, and pain respectively. RESULTS: Overall, 336 patients were divided into two groups: 225 in the full-analysis set (primary outcome 225; secondary outcomes 170) and 156 in the per-protocol set (primary outcome 156; secondary outcomes 110). In both analyses, lymphatic venous anastomosis with non-operative decongestive therapy was more effective in preventing cellulitis than non-operative decongestive therapy alone; the difference between groups in reducing cellulitis frequency over 6 months was -0.35 (95 per cent c.i. -0.62 to -0.09; P = 0.010) in the full-analysis set (FAS) and -0.60 (-0.94 to -0.27; P = 0.001) in the per-protocol set (PPS) Limb circumference and pain were not significantly different, but lymphatic venous anastomosis reduced thigh area hardness (proximal medial and distal and lateral proximal). Four patients experienced contact dermatitis with non-operative decongestive therapy alone. CONCLUSION: Lymphatic venous anastomosis in combination with non-operative decongestive therapy prevents cellulitis. REGISTRATION NUMBER: UMIN00025137, UMIN00031462.

Smooth versus Textured Implant Breast Reconstruction: Patient-Reported Outcomes and Complications.

BACKGROUND: The association between textured surface breast implants and breast implant-associated anaplastic large cell lymphoma has led to an increase in surgical procedures to exchange textured devices to smooth surface implants. Because patient satisfaction is an integral part of breast reconstruction, the purpose of this study was to compare patient-reported outcomes between smooth and textured implant recipients. METHODS: Patients aged 18 years or older who underwent implant-based postmastectomy breast reconstruction with either smooth or textured devices from 2009 to 2017 and completed the BREAST-Q patient-reported outcome measure following reconstruction were included in this analysis. The primary outcomes of interest were mean and median BREAST-Q scores and postoperative complications. RESULTS: Overall, 1077 patients were included-785 who underwent breast reconstruction with smooth implants and 292 who underwent breast reconstruction with textured implants. No statistical differences were observed between the textured and smooth implant groups for any of the BREAST-Q domain scores at any of the early (3-month) to late (2-year) postoperative time points. Smooth implant recipients reported significantly more rippling (p = 0.003) than textured implant recipients. In contrast, textured implant recipients had a higher rate of cellulitis than smooth implant recipients (p = 0.016). CONCLUSIONS: These data suggest that postoperative satisfaction with breasts or health-related quality of life following immediate postmastectomy implant-based breast reconstruction is likely independent of implant surface type. However, smooth breast implants may result in more rippling. The authors' findings represent an important aid in counseling patients who have questions about the risks and benefits of replacing their textured implants with smooth surface devices.

[Non-Necrotizing Acute Dermo-Hypodermal Infections: Erysipela and Infectious Cellulitis]. / Dermo-Hipodermites Bacterianas Agudas Não Necrotizantes: Erisipela e Celulite Infeciosa.

Non-necrotizing acute dermo-hypodermal infections are infectious processes that include erysipela and infectious cellulitis, and are mainly caused by group A ß-haemolytic streptococcus. The lower limbs are affected in more than 80% of cases and the risk factors are disruption of cutaneous barrier, lymphoedema and obesity. Diagnosis is clinical and in a typical setting we observe an acute inflammatory plaque with fever, lymphangitis, adenopathy and leucocytosis. Bacteriology is usually not helpful because of low sensitivity or delayed positivity. In case of atypical presentations, erysipela must be distinguished from necrotizing fasciitis and acute vein thrombosis. Flucloxacillin and cefradine remain the first line of treatment. Recurrence is the main complication, so correct treatment of the risk factors is crucial.

As dermo-hipodermites bacterianas agudas não necrotizantes são processos infeciosos que incluem a erisipela e a celulite infeciosa, e são geralmente causadas por estreptococos ß­hemolíticos do grupo A. Em mais de 80% dos casos situam-se nos membros inferiores e são fatores predisponentes a existência de solução de continuidade na pele, o linfedema crónico e a obesidade. O seu diagnóstico é essencialmente clínico e o quadro típico baseia-se na presença de placa inflamatória associada a febre, linfangite, adenopatia e leucocitose. Os exames bacteriológicos têm baixa sensibilidade ou positividade tardia. Nos casos atípicos é importante o diagnóstico diferencial com a fasceíte necrotizante e a trombose venosa profunda. A flucloxacilina ou a cefradina são os fármacos de primeira linha. A recidiva constitui a complicação mais frequente, sendo fundamental o correto tratamento dos fatores de risco.

Treatment of toes as an integrated part of infection control for advanced lower limb lymphedema.

The aim of this study was to compare the incidence of infection and verrucous hyperkeratosis in patients who underwent surgery for advanced lymphedema according to the algorithm designed by the senior author, and were treated concurrently with/without toe treatment. A case series (Between 2004-2015) of 46 patients with unilateral advanced lower limb lymphedema was reviewed. Lymphoscintigraphy was used for evaluation of lymphedema severity. The ICG lymphography was used for staging. Fibrosis and skin induration were reflected by the tonicity. They were divided into two groups: (1) patients who underwent further treatment of toes according to the algorithm, and (2) patients who did not have toe-related treatment. Infection episodes and verrucous hyperkeratosis were recorded. There were 21 and 25 patients in Groups 1 and 2, respectively. All lymphoscintigrams showed severe dermal backflow with severe stagnation by 2.5 h after injection of Tc-99 colloid. All patients were stage IV or V. Tonicity values of skin were <60. Group 1 was reduced to an average of 0.6 episodes per year in the past year of follow-up, and Group 2 was reduced to an average of 1.5 episodes per year in the past year of follow-up (p <0.001). The average frequency of preoperative cellulitis was 3.6 episodes per year. The occurrence of verrucous hyperkeratosis was observed in 14.3% and 32% of Groups 1 and 2, respectively. The incidences of cellulitis and verrucous hyperkeratosis were significantly lower in Group 1 than in Group 2 (p <0.001). To achieve successful control of infection, they should be treated carefully according to the strategy described above.

Robotic-assisted inguinal lymphadenectomy: a systematic review.

BACKGROUND: Lymphadenectomy represents the standard treatment for various types of cancer. The introduction of robotics in lymph node dissection may have an important impact on post-lymphadenectomy complications. METHODS: A systematic literature review was performed. RESULTS: In our review, robotic inguinal lymphadenectomy was performed on 51 patients. Penile squamous cell carcinoma was the most common histological type of the primary neoplasia. No intra-operative complications were reported. One case of conversion to open was reported. The mean duration of hospitalization was 2 days. The duration of drainage ranged from 7 to 72 days. The most common postoperative complications were lymphocele (13.7%), lymphedema (7.8%), cellulitis (7.8%), seroma (3.9%), abscess (3.9%), wound breakdown/wound infection (3.9%), sepsis (1.9%), prolonged lymphorrhea (1 out of 51 patients, 1.9%) and skin necrosis (1 out of 51 patients, 1.9%). CONCLUSIONS: Until now there has not been sufficient evidence regarding the role of robotics in groin lymph node dissection, though this approach appears to be safe and oncologically effective, with morbidity rates relatively lower compared to open surgery.

Multivariate analysis of risk factors for Nuss bar infections: A single center study.

BACKGROUND/PURPOSE: Our previously published data suggested several risk factors for infection after the Nuss procedure. We aimed to further elucidate these findings. METHODS: An IRB-approved (14-03-WC-0034), single institution, retrospective review was performed to evaluate the incidence of postoperative Nuss bar infections associated with seven variables. These were subjected to bivariate and multivariable analyses. A broad definition of infection was used including cellulitis, superficial infection with drainage, or deep infection occurring at any time postoperatively. RESULTS: Over 7years (4/1/2009-7/31/2016), 25 (3.2%) of 781 patients developed a postoperative infection after primary Nuss repair. Multivariable analyses demonstrated an increased risk of infection with perioperative clindamycin versus cefazolin for all infections (AOR 3.72, p=.017), and specifically deep infections (AOR 5.72, p=.004). The risk of a superficial infection was increased when antibiotic infusion completed >60min prior to incision (AOR 10.4, p=.044) and with the use of peri-incisional subcutaneous catheters (OR 8.98, p=.008). CONCLUSION: Following primary Nuss repair, the rate of deep bar infection increased with the use of perioperative clindamycin rather than cefazolin. The rate of superficial infection increased when perioperative antibiotic infusion was completed more than 60min prior to incision and with the use of peri-incisional subcutaneous catheters. Further studies are needed to better understand these findings. TYPE OF STUDY: Retrospective chart review. LEVEL OF EVIDENCE: Level III treatment study.

A comparison of programmable and nonprogrammable compression devices for treatment of lymphoedema using an administrative health outcomes dataset.

BACKGROUND: Patients with lymphoedema experience lifelong swelling and recurrent cellulitis despite use of complete decongestive therapy. Pneumatic compression devices (PCDs), including nonprogrammable and programmable devices that meet individual patient needs, support long-term self-care in the home. OBJECTIVES: Patients with either a nonprogrammable device (NP-PCD) or a dynamic pressure programmable device [P-PCD; Flexitouch® (Tactile Medical, Minneapolis, MN, U.S.A.)] were evaluated to compare associated clinical and health utilization outcomes pre-/postdevice acquisition. METHODS: Retrospective analysis of deidentified administrative claims from 2007 through 2013 of a large U.S. insurer. Outcome variables included rates of lymphoedema-related cellulitis, manual therapy use, outpatient services and inpatient hospitalizations. Multivariate regression analysis was performed to (i) compare outcomes for the 12 months pre- and postdevice acquisition and (ii) compare these two device types for their treatment-associated benefits. RESULTS: The sample consisted of 1013 NP-PCD and 718 P-PCD recipients. Compared with the NP-PCD group, P-PCD patients' baseline cellulitis rate was higher, whereas their postdevice cellulitis rate was lower. In the cancer cohort, the NP-PCD group had a 53% reduction in episodes of cellulitis (from 17·9% to 8·5%), compared with a greater 79% reduction in the P-PCD group (from 23·7% to 5·0%) (P < 0·001). In the noncancer cohort, the P-PCD group also experienced a larger 76% decline (from 31·0% to 7·4%) vs. 54% decline (from 22·9% to 10·6%) in cellulitis rates (P = 0·003). Outpatient service use reduced in both device groups, with greater reductions observed in the P-PCD group. Both device groups experienced reductions in manual therapy use. Inpatient hospitalizations were largely stable with reductions observed only in the noncancer cohort of the P-PCD group. CONCLUSIONS: P-PCD receipt was associated with superior lymphoedema-related health outcomes and reductions in cellulitis.

Impact of evidence-based interventions on wound complications after cesarean delivery.

BACKGROUND: A number of evidence-based interventions have been proposed to reduce post-cesarean delivery wound complications. Examples of such interventions include appropriate timing of preoperative antibiotics, appropriate choice of skin antisepsis, closure of the subcutaneous layer if subcutaneous depth is ≥2 cm, and subcuticular skin closure with suture rather than staples. However, the collective impact of these measures is unclear. OBJECTIVE: We sought to estimate the impact of a group of evidence-based surgical measures (prophylactic antibiotics administered before skin incision, chlorhexidine-alcohol for skin antisepsis, closure of subcutaneous layer, and subcuticular skin closure with suture) on wound complications after cesarean delivery and to estimate residual risk factors for wound complications. STUDY DESIGN: We conducted a secondary analysis of data from a randomized controlled trial of chlorhexidine-alcohol vs iodine-alcohol for skin antisepsis at cesarean delivery from 2011-2015. The primary outcome for this analysis was a composite of wound complications that included surgical site infection, cellulitis, seroma, hematoma, and separation within 30 days. Risk of wound complications in women who received all 4 evidence-based measures (prophylactic antibiotics within 60 minutes of cesarean delivery and before skin incision, chlorhexidine-alcohol for skin antisepsis with 3 minutes of drying time before incision, closure of subcutaneous layer if ≥2 cm of depth, and subcuticular skin closure with suture) were compared with those women who did not. We performed logistic regression analysis limited to patients who received all the evidence-based measures to estimate residual risk factors for wound complications and surgical site infection. RESULTS: Of 1082 patients with follow-up data, 349 (32.3%) received all the evidence-based measures, and 733 (67.7%) did not. The risk of wound complications was significantly lower in patients who received all the evidence-based measures compared with those who did not (20.3% vs 28.1%; adjusted relative risk, 0.75; 95% confidence interval, 0.58-0.95). The impact appeared to be driven largely by a reduction in surgical site infections. Among patients who received all the evidence-based measures, unscheduled cesarean delivery was the only significant risk factor for wound complications (27.5% vs 16.1%; adjusted relative risk, 1.71; 95% confidence interval, 1.12-2.47) and surgical site infection (6.9% vs 1.6%; relative risk, 3.74; 95% confidence interval, 1.18-11.92). Other risk factors, which include obesity, smoking, diabetes mellitus, chorioamnionitis, surgical experience, and skin incision type, were not significant among patients who received all of the 4 evidence-based measures. CONCLUSION: Implementation of evidence-based measures significantly reduces wound complications, but the residual risk remains high, which suggests the need for additional interventions, especially in patients who undergo unscheduled cesarean deliveries, who are at risk for wound complications even after receiving current evidence-based measures.

Our supramicrosurgical experience of lymphaticovenular anastomosis in lymphoedema patients to prevent cellulitis.

OBJECTIVE: Aim of this paper is to present our reduction of the frequency of cellulitis before and after supramicrosurgical lymphaticovenular anastomosis (s-LVA) in lymphoedema patients, and discuss the possibility to perform this technique outside Japan. PATIENTS AND METHODS: 37 patients affected by lymphoedema were enrolled. All patients received preoperative indocyanine green lymphography. Under local anaesthesia s-LVA was performed on all patients. All patients were followed for 1 year. Lymphoedema was staged using the lymphoedema staging classification recommended by the International Society of Lymphology. Cellulitis rate was recorded for all patients the year before and after the s-LVA. A t-test was used to evaluate differences in the frequency of cellulitis the year before surgery and the year following surgery. RESULTS: Cellulitis incidence decreased in all patients, with a mean 1.7 cases the year before s-LVA and 0.1 the year after s-LVA. A significant difference between preoperative and postoperative cellulitis rate was found (p = 0.0012). CONCLUSIONS: This study reports our s-LVA case series of lymphoedema patients. With the proper learning curve, s-LVA may be reproduced and lymphoedema patients may gain a better quality of life and a reduced cellulitis rate.

The experience of intramuscular benzathine penicillin for prophylaxis of recurrent cellulitis: A cohort study.

BACKGROUND/PURPOSE: Recurrent cellulitis is an important clinical issue but the optimal strategy for prophylaxis is not determined. Intramuscular benzathine penicillin at a 4-week interval had been adopted in our hospital and the study was conducted to evaluate the efficacy. METHODS: From January 1, 2009 to May 31, 2013, all patients aged ≥ 18 year, with a history of recurrent cellulitis and having received at least three shots of intramuscular benzathine penicillin for prophylaxis were retrospectively recruited for analysis. Two treatment periods (prophylaxis period and nonprophylaxis period) were defined. The effects of benzathine penicillin prophylaxis and patient characteristics on the incidence rate of recurrent cellulitis were analyzed using Poisson regression model. RESULTS: A total of 72 patients were enrolled, including 26 (36.1%) men. The most common underlying conditions were past surgery at the proximal side of the affected limb (38, 52.8%), malignancy (31, 43.1%), and diabetes mellitus (24, 33.3%). The incidence rate of recurrent cellulitis in the prophylaxis period was 0.73 episode/patient-year, significantly lower than that of 1.25 episodes/patient-year in the nonprophylaxis period (p < 0.001). Tinea pedis was a significant factor associated with increasing incidence of recurrent cellulitis in our cohort. CONCLUSION: Intramuscular benzathine penicillin at a 4-week interval may be an effective prophylactic strategy to reduce the incidence of cellulitis. Further studies are necessary to determine the factors associated with failure of prophylaxis as well as optimal individualized dosage and dosing interval of the prophylactic agent.

The contribution of a collagen-fibrin patch (Tachosil) to prevent the postoperative lymphatic complications after groin lymphadenectomy: a double institution observational study.

OBJECTIVE: Postoperative morbidity associated with groin lymphadenectomy remain high and still represents a major concern for this patients. The aim of this study was to confirm the efficacy of TachoSil(®) in preventing postoperative complications after inguinofemoral lymphadenectomy for gynecological malignancy. STUDY DESIGN: An observational study was conducted to evaluate the incidence of postoperative complications among 49 patients (TachoSil(®) group=24; control group=25) underwent groin dissection enrolled in two Italian Department of Gynecology Oncology from 2011 to 2014. RESULTS: A total of 74 inguinal dissections were performed. Bilateral groin dissection was performed in 25 patients (Tachosil group=10; group 2=15). Patients in TachoSil(®) group showed a lower daily drainage volume with a mean volume of 84 ml (range 30-465) vs. 143 ml (range -72 to 413) in the control group (p=.004), and a lower total drainage volume with a mean of 540 ml (range 90-930) vs. 900 ml (range 200-3270) for Tachosil and control group, respectively. A lower incidence of lymphocyst required drainage, cellulitis, wound infection and late lymphedema was observed in TachoSil group even without reaching statistical significance. CONCLUSIONS: This observational study confirmed that the use of TachoSil(®) seems to be highly effective in reducing the rate of postoperative lymphorrea and postoperative complications after groin dissection in case of gynecological malignancies. Larger multicenter prospective study is advisable to validate our preliminary results.

Risk factors and management of Nuss bar infections in 1717 patients over 25 years.

PURPOSE: An increase in postoperative infections after Nuss procedures led us to seek risks and review management. We report potential risk factors and make inferences for prevention of infections. METHODS: An IRB-approved retrospective chart review was used to evaluate demographic, clinical, surgical, and postoperative variables of patients operated on between 10/1/2005 and 6/30/2013. Those with postoperative infection were evaluated for infection characteristics, management, and outcomes with univariate analyses. RESULTS: Over this 8-year period (2005-2013), 3.5% (30) of 854 patients developed cellulitis or infection, significantly more than 1.5% (13) in our previous report of 863 patients, 1987-2005 (p=.007). The most frequent organism cultured was methicillin-sensitive Staphylococcus aureus. Patients who were given clindamycin preoperatively (5 of 26 patients) had higher infection rates than those who received cefazolin (25 of 828) (19% vs 3%, p<.001). Patients treated with a peri-incisional ON-Q (I-Flow, Kimberly-Clark, Irvine, CA) also had higher infection rates (8.3% vs 2.4%, p<.001). Of the 30 patients who developed an infection, eighteen (60%) with cellulitis or superficial infections did not require surgical treatment or early bar removal. The other twelve patients (40%) with deep hardware infections required an average of 2.2 operations (range 1-6), with 3 (25%) requiring removal of their stabilizer and 3 (25%) requiring early bar removal. None of these three patients experienced recurrence of pectus excavatum at 2 to 4 years of follow-up. CONCLUSION: Preoperative antibiotic selection and use of ON-Q's may influence infection rates after Nuss repair. Nuss bars could be preserved in 90% of all patients with an infection and even 75% of those with a deep hardware infection. Attempts to retain the bar when an infection occurs may help prevent pectus excavatum recurrence. Level of Evidence=III.

A single pre-operative antibiotic dose is as effective as continued antibiotic prophylaxis in implant-based breast reconstruction: A matched cohort study.

PURPOSE: Infections following implant-based breast reconstruction can lead to devastating consequences. There is currently no consensus on the need for post-operative antibiotics in preventing immediate infection. This study compared two different methods of infection prevention in this group of patients. METHOD: A retrospective matched cohort study was performed on consecutive women undergoing implant-based breast reconstruction at University Health Network, Toronto (November 2008-December 2012). All patients received a single pre-operative intravenous antibiotic dose. Group A received minimal interventions and Group B underwent maximal prophylactic measures. Patient (age, smoking, diabetes, co-morbidities), oncologic and procedural variables (timing and laterality) were collected. Univariate and multivariate logistic regression were performed to compare outcomes between the two groups. RESULTS: Two hundred and eight patients underwent 647 implant procedures. After matching the two treatment groups by BMI, 94 patients in each treatment group yielding a total of 605 implant procedures were selected for analysis. The two groups were comparable in terms of patient and disease variables. Post-operative wound infection was similar in Group A (n = 11, 12%) compared with Group B (n = 9, 10%; p = 0.8). Univariate analysis revealed only pre-operative radiotherapy to be associated with the development of infection (0.004). Controlling for the effect of radiotherapy, multivariate analysis demonstrated that there was no statistically significant difference between the two methods for infection prevention. CONCLUSIONS: Our findings suggest that a single pre-operative dose of intravenous antibiotics is equally as effective as continued antibiotic prophylaxis in preventing immediate infection in patients undergoing implant-based breast reconstructions.

[Special surgical complications in chronic inflammatory bowel diseases]. / Spezielle chirurgische Komplikationen bei chronisch entzündlichen Darmerkrankungen.

After colorectal and anorectal interventions for chronic inflammatory bowel diseases, specific complications can occur.In Crohn's disease these complications mainly occur after proctocolectomy. Pelvic sepsis can be prevented by omentoplasty with fixation inside the pelvis. A persisting sepsis of the sacral cavity can be treated primarily by dissection of the anal sphincter which ensures better drainage. In cases of chronic sacral sepsis, transposition of the gracilis muscle is a further effective option. Early recurrence of a transsphincteric anal fistula should be treated by reinsertion of a silicon seton drainage.Complications after restorative proctocolectomy are frequent and manifold (35%). The main acute complications are anastomotic leakage and pelvic sepsis. Therapy consists of transperineal drainage of the abscess with simultaneous transanal drainage. Late complications due to technical and septic reasons are still a relevant problem even 36 years after introduction of this operative technique. A consistent approach with detailed diagnostic and surgical therapy results in a 75% rescue rate of ileoanal pouches.

Eventos adversos en la terapia farmacológica de la enfermedad inflamatoria intestinal / Adverse events associated with the treatment of inflammatory bowel disease

Background: The purpose of inflammatory bowel disease (IBD) treatment is to achieve resolution of symptoms and remission of disease with a minimum of adverse events (AE). Aim: To report AE of different prescriptions used for the treatment of IBD. Material and Methods: Analysis of a registry of patients with IBD held at a private clinic from 1976 to 2013. All used medications, the occurrence and severity of AE were recorded. Results: The records of 346 patients aged 16 to 86 years, 74% with ulcerative colitis, were analyzed. The most commonly type of medications prescribed were 5-aminosalicylates (5-ASAs) in 329 patients (92%), followed by adrenal steroids in 218 (61%). Forty nine AE were recorded in the same number of patents (14%). These were more common in patients with Crohn disease (n = 19, 21%). An univariate analysis, demonstrated that extra-intestinal manifestations, hospitalizations secondary to IBD crisis, requirement of surgery and treatment with steroids, immunosuppressants or biologic agents were significantly associated with the presence of AE. AEs were more common with immunosuppressants, followed by 5-ASAs and steroids. Discontinuation of therapy was required in 79, 100 and 43% of patients taking these medications, respectively. Twenty percent of AEs were severe. Leukopenia and pancytopenia along with alopecia were the most common AEs attributable to azathioprine. Conclusions: The occurrence of AEs in patients with IBD is uncommon. Even inmunosuppressants or biologic agents have a low rate of AE and most of them mild.

Lymphaticovenular anastomosis to prevent cellulitis associated with lymphoedema.

BACKGROUND: One of the complications of lymphoedema is recurrent cellulitis. The aim was to determine whether lymphaticovenous anastomosis (LVA) was effective at reducing cellulitis in patients with lymphoedema. METHODS: This was a retrospective review of patients with arm/leg lymphoedema who underwent LVA. The frequency of cellulitis was compared before and after surgery. The diagnostic criteria for cellulitis were a fever of 38·5°C or higher, and warmth/redness in the affected limb(s). RESULTS: A total of 95 patients were included. The mean number of episodes of cellulitis in the year preceding surgery was 1·46, compared with 0·18 in the year after surgery (P < 0·001). CONCLUSION: LVA reduced the rate of cellulitis in these patients with lymphoedema.

The impact of postoperative nausea and vomiting prophylaxis with dexamethasone on postoperative wound complications in patients undergoing laparotomy for endometrial cancer.

BACKGROUND: Dexamethasone is widely used for postoperative nausea and vomiting (PONV) prophylaxis. However, there are limited data on the risk of wound complications associated with single-dose dexamethasone use for this purpose. We performed this retrospective study to determine whether intraoperative dexamethasone for PONV prevention increases the risk or severity of postoperative wound complications. METHODS: Women who underwent laparotomy for endometrial cancer between 2002 and 2007 were identified from a tumor registry. Perioperative records were reviewed to determine dexamethasone administration. Medical records were reviewed to identify wound complications including cellulitis, superficial surgical site infection, wound separation, and fascial dehiscence. Wound care needs and time to complete wound healing were compared based on dexamethasone exposure. The rate of wound complications was also compared based on dexamethasone dose. Baseline characteristics and perioperative details were evaluated for independent associations with wound complications. Logistic regression analyses were performed to predict the occurrence of wound complications. RESULTS: Four hundred thirty-one patients met inclusion criteria; 192 (44.6%) received dexamethasone (4-12 mg) and 31.1% developed a wound complication. In unadjusted analysis, there was no difference in the risk of developing a wound complication based on dexamethasone exposure; 53 of 192 patients (27.6%) who received dexamethasone developed a wound complication, compared with 81 of 239 (33.9%) who did not receive dexamethasone: odds ratio (OR) (95% confidence interval [CI]) = 0.74 (0.49, 1.13), P = 0.16. There was no difference in the distribution of wound complication types based on receipt of dexamethasone (P = 0.71), or in the incidence of wound complications based on the dose of dexamethasone (P = 0.48). Of patients who developed a wound complication, there was no difference in the need for IV antibiotics, vacuum-assisted wound closure, or in the rate of fascial dehiscence based on dexamethasone exposure. The time to complete wound healing was not different between the 2 cohorts (P = 0.48). In univariate analysis, higher body mass index (BMI), higher estimated blood loss, smoking, and longer duration of surgery were predictors of wound complications. Smoking (OR [95% CI]: 2.0 [1.3, 3.2], P = 0.003) and BMI (OR [95% CI]: 1.2 [1.1, 1.3], P = 0.0003) were the only significant predictors of wound complications in the multivariate model, whereas dexamethasone remained a nonsignificant predictor (OR [95% CI]: 0.7 [0.5, 1.1], P = 0.12). CONCLUSION: Intraoperative dexamethasone for PONV prophylaxis does not seem to increase the rate or severity of postoperative wound complications in women undergoing laparotomy for endometrial cancer. BMI and smoking were significant predictors of wound complications in this patient population.
