Urethral obstruction due to pseudomembranous cystitis in a domestic shorthair cat

AbstractA 2‐year‐old, male, neutered, domestic shorthair cat presented with acute onset lethargy, anorexia, stranguria, dysuria without micturition. Routine blood tests demonstrated hyperkalaemia, azotaemia and metabolic acidosis. Abdominal ultrasound revealed a bi‐compartmentalised urinary bladder, with intravesical mineralised septa. The patient was diagnosed with urethral obstruction secondary to pseudomembranous cystitis. Following initial medical management, an exploratory celiotomy and cystotomy were performed, which revealed a complete fluid‐filled intravesical pseudomembranous sac, which extended via a long thin pedicle into the proximal urethra. The pseudomembranous sac was excised. Cystotomy and abdominal wound closure were routine. Post‐operative stranguria resolved with medical management within 9 days. Bacterial culture of the urinary bladder wall demonstrated no growth. Histopathology confirmed a pseudomembrane, which was composed predominantly of eosinophilic proteinaceous material and extravasated erythrocytes, with some neutrophils and cellular debris. Four months post‐operatively, no recurrence of the clinical signs has been reported.

Scar revision for persistent pain and activity limitation after exploratory laparotomy in infancy: A case series

AbstractExploratory laparotomy in neonates is typically performed via a transverse laparotomy incision. However, this incision may be complicated by poor cosmesis and scar contracture. In three patients, primary gastroenterologists identified significant scar contractures that resulted in pain and limitations with physical activity, necessitating surgical referrals. All patients required subsequent surgical revision of their scar, which involved creation of skin flaps, repair of abdominal wall hernias if present, and reapproximation of the subcutaneous tissue. We describe this phenomenon and the resultant need for surgical management to raise awareness of these late complications and suggest subcutaneous tissue reapproximation should be performed when possible during abdominal wall closure.

Comparison of continuous versus modified continuous SMEAD jones “far-near-near-far” suturing technique for abdominal wall closure in emergency midline laparotomy wound in terms of wound dehiscence.

Objective: To compares the frequency of wound dehiscence in emergency midline laparotomy wound closure using the modified continuous Smead-Jones technique to the continuous method. Study Design: Randomized Controlled Trial. Setting: Department of Surgery, Allied Hospital Faisalabad. Period: December 20, 2022, to June 20, 2023. Methods: Every one of the one hundred patients having an emergency exploratory laparotomy gave written informed consent. They were split into two groups at random: Group A received continuous closure using prolene #01 suture bites placed 1 cm from the margin and 1 cm apart, and Group B received a modified Smead-Jones technique where suture bites were taken 1.5 cm from the wound margin and 0.5 cm linea alba on either side with prolene # 01 with suture placed 2cm apart. Wound dehiscence was checked following operational definitions. Results: The study's mean age was determined to be 40.18+13.53 years for Group A and 41.18+13.33 years for Group B. Males made up 58.0% (n = 29) of Group A and 72.0% (n = 36) of Group B, while females made up 42.0% (n = 21) of Group A and 28% (n = 14) of Group B. The mean wound dehiscence was 28% in Group B and 10% in Group 2. The p-value for this study was 0.022. Conclusion: When compared to the traditional continuous abdominal wound closure technique, the wound dehiscence rate was significantly lower with the modified continuous smead-jones abdominal wound closure method.

Gender-affirming DIEP Flap Breast Augmentation.

Implant-based techniques have been the mainstay of gender-affirming breast augmentation (GABA). Here we describe a novel autologous technique for GABA. We provide a single-patient case report of gender-affirming deep inferior epigastric artery perforator (DIEP) flap breast augmentation. World Professional Association for Transgender Health guidelines were followed according to Standards of Care, version 8. Prepectoral tissue expanders were placed at the time of the patient's facial feminization surgery. DIEP flaps were then used for bilateral breast augmentation. Planned revisions were made about 5 months later. Breast augmentation was performed successfully with DIEP flaps, and the patient was satisfied with her outcome. No complications occurred. Anatomic differences to cisgender women were noted, including relatively thick musculature of the abdominal wall and chest as well as tight anterior abdominal fascial closure. Advantages compared with implant-based GABA were also noted, including feminization of the abdomen and avoidance of potential implant related complications. We report a novel approach to GABA. Our approach borrows well-established techniques with demonstrated efficacy and high satisfaction in postmastectomy breast reconstruction and even cosmetic purposes. However, sex- and hormone-influenced anatomic differences required some modifications compared with postmastectomy DIEP flap reconstruction.

Use of liposomal bupivacaine in cats undergoing gastrointestinal surgery is associated with lower doses of full µ-opioid agonists postoperatively

Objectives The aim of the study was to analyze the association of the administration of liposomal bupivacaine (Nocita) with postoperative opioid use in cats undergoing gastrointestinal surgery, as well as to analyze the administration of antiemetics postoperatively in this study population to qualify the degree of nausea related to opioid administration. Methods Records of 187 cats undergoing gastrointestinal surgery across two institutions, the Matthew J Ryan Veterinary Hospital at the University of Pennsylvania and the University of Florida Small Animal Hospital, were analyzed for multilayer liposomal bupivacaine infiltration at the time of abdominal closure, postoperative injectable opioid use and postoperative injectable antiemetic use. Results Cats that were administered liposomal bupivacaine at the time of abdominal closure received significantly lower doses of full µ-opioid agonists postoperatively. Significantly more cats that received liposomal bupivacaine were managed with full µ + partial µ-opioid agonists postoperatively than any other opioid profile. Cats that received liposomal bupivacaine received lower doses of ondansetron in hospital compared with cats that did not receive liposomal bupivacaine. Conclusions and relevance This study suggests that in cats requiring analgesia postoperatively, the use of liposomal bupivacaine at closure reduces the use of full µ-opioid agonists postoperatively. In addition, more patients that received liposomal bupivacaine were de-escalated from full µ-opioid agonists to partial µ-opioid agonists during their hospital stay, suggesting that less analgesia was required throughout their hospitalization. Lastly, lower doses of ondansetron, a typical second-line antinausea medication after gastrointestinal surgery, were used in cats that received liposomal bupivacaine, which may suggest less postoperative nausea.

Rupture of fetal membrane in ectopic tubal pregnancy: A case report and literature review.

Ruptured tubal pregnancies occurring in the second trimester are rare; yet, they pose a critical risk of life-threatening hemorrhage. This study aims to highlight the importance of timely surgical intervention in such cases to prevent fatal outcomes. The case underscores the diagnostic and therapeutic challenges that arise when distinguishing between tubal and abdominal pregnancies, particularly in the presence of hemoperitoneum, which can obscure imaging results. We present a case involving the spontaneous rupture of a tubal pregnancy at 15 weeks and 3 days of gestation. The patient exhibited elevated beta-human chorionic gonadotropin levels. Initial transabdominal ultrasound suggested an abdominal pregnancy, and computed tomography scans supported these findings. Urgent midline laparotomy revealed the condition to be a tubal pregnancy, contrary to initial imaging. The surgical procedure included the removal of the gestational sac and the affected fallopian tube, followed by abdominal closure. Hemoperitoneum was noted to compromise the accuracy of imaging modalities, complicating the preoperative diagnosis. Histopathological examination confirmed the diagnosis of tubal pregnancy. The patient had an uneventful recovery and was discharged 7 days post-surgery with stable hemoglobin levels. This case underscores the importance of considering the differential diagnosis of abdominal versus tubal pregnancy in the presence of hemoperitoneum, due to their differing clinical management needs. It offers insights that may guide clinicians in the timely diagnosis and treatment of advanced tubal pregnancies, where prompt surgical intervention is critical.

Rectus Muscle Flap-augmented Closures in Wide-gap Exstrophy Bladder.

Wound dehiscence is one of the main complications in complete primary repair of exstrophy (CPRE). In our pediatric urology unit, we have switched to the use of inferior epigastric artery based rectus abdominis flap cover for abdominal wall closure in addition to measures like osteotomy and postoperative hip spica. to assess the efficacy of Recus abdominis flap in prevenion of wound dehisence. This study was conducted from June 2014 to June 2021 comparing two groups of the patients; group I consisted of thirty patients of CPRE with rectus flap repair of abdominal wall (CPRE-RF) and group II consisted of thirty patients with CPRE without rectus flap. Clinical and surgical details, including the outcome with regards to wound dehiscence and continence, were recorded. The mean age of the patients in CPRE-RF was 5 months and that with only CPRE was 4.6 months. Mean pubic diastasis in Group l was 4.8± 1.07 cm and that of Group II was 4.6±1.3 cm. None of the patients in CPRE-RF had wound dehiscence or bladder prolapse while as 6 patients in CPRE alone had wound dehiscence and 1 had bladder prolapse. This difference was statistically significant. Primary bladder continence was achieved in 4 patients in CPRE-RF and 3 patients in CPRE group. Hypospadias had almost similar occurrence in the two groups. One patient in each group had bladder neck fistula. Use of rectus muscle flap in complete Primary Repair ofExtrophy bladder helps in prevention of wound dehiscence and contributes in achievement of final goal of continence in wide gap pubic diatasis.

EP202 - Mesh-Mediated Fascial Traction (MMFT) and Negative Pressure Abdominal Dressing (ABTHERA): Useful in Difficult Open Abdomens?

Abstract Background Challenging abdominal surgical emergencies may require an 'Open Abdomen (OA)' as a life-saving procedure. OA has serious complications: wound infection, fluid and protein loss, catabolic state, loss of abdominal domain, and entero-atmospheric fistula. To assess the efficacy of mesh-mediated fascial traction (MMFT) & Abthera Dressing in achieving definitive abdominal closures. Patients and Method Retrospective analysis of prospectively collected data of 6 patients managed between August and November 23 in a large DGH. Following laparotomy and management of primary pathology, Abthera Dressing combined with bilateral continuous 2-0 PDS suture fixation at 0.5cm gap of macroporous Prolene (Merinium, Meril Life) meshes to each rectus sheath followed by sequential midline mesh traction closure over a time period that allowed subsequent definitive abdominal wound closure. Data collection included patient demographics (age, sex, BMI, ASA), intervention details for OA, wound characteristics, follow-up, and outcome. Results Six included M: F 4:2, age 61* (40-76 ) years, BMI 30* ( 24-35), ASA 3. Three were strangulated incisional hernia, 2 burst abdomens from faecal peritonitis, and 1 necrotizing fasciitis. Initial wound length 25*(20-32) cm, width 12.5* (4-17) cm after management of primary pathology reduced to width 4.5* (0-9) cm through MMFT and Abthera Dressing followed by definitive abdominal closure. Relook surgery required were 4* (1-9) with one full and 4 bridged mesh closures. Length of stay 39* (14-74) days. One death from respiratory failure. Conclusion The study highlights the benefit of MMFT & Abthera Dressing in achieving definitive abdominal closure for challenging OA where primary abdominal closure was not possible. * Median

SP5.2 - Reducing Elective Colorectal Surgical Site Infections with Change of Gloves and Instruments Prior to Abdominal Closure; A Multicycle Audit

Abstract Aims Surgical site infections (SSI) carry a significant impact on patient morbidity, length of stay and antibiotic resistance. Our local colorectal unit has made several interventions over many years with no significant nor sustained improvement in the rate of SSI. The ChEETAh trial (Lancet, 2022) demonstrated a reduction in the rate of 30-day SSI by 13% with routine change of gloves and instruments (COGI) prior to abdominal closure. We aim to reduce our rate of SSI through implementation of COGI prior to abdominal closure; involving whole scrub team change of gloves and use of sterile instruments. Methods Adults undergoing elective colorectal surgery with an abdominal wound greater than 5cm were eligible for this study. Diagnosis of SSI was made based on at least one clinical indicator of infection or at least one symptom of SSI with data collection over 3 cycles spanning 11 months using clinical notes, imaging and microbiology results. The primary outcome was the diagnosis of a SSI involving the skin, subcutaneous, muscle or fascial layer up to 30 days post-operatively. Results The baseline SSI rate prior to intervention was audited at 29%. After implementation of COGI the rate fell to 23%. Further reinforcement of COGI and team education has demonstrated a further decrease in SSI to 15%. This has been sustained across a 6-month period post intervention. Conclusions Change of gloves and instruments is an effective, reliable and sustainable method to reduce the rate of surgical site infection in elective colorectal abdominal surgery.

Tensile testing in feline ventral abdominal coeliotomy closure with different sizes of polydioxanone suture material: a biomechanical study.

The aim of this study was to evaluate, in vitro, the load and type of failure of the sutured ventral abdominal fascia of cats with different sizes of suture material made of polydioxanone (PDX) (2-0, 3-0, 4-0, 5-0 USP). A total of 32 samples of the ventral abdominal wall from 16 cadaveric cats were harvested using an hourglass-shaped template. The samples were sectioned longitudinally along the linea alba and then sutured together in a continuous pattern using four different randomly assigned sizes of pdx suture material (2-0, 3-0, 4-0, 5-0 USP). A universal testing machine was used for linear distraction of the samples. The tensile strength and type of failure were recorded and analysed. Three types of failure were defined: suture material failure (S), suture line failure (T1) and failure of the abdominal wall further away from the linea alba (T2). The frequency of suture material failure decreased with increasing suture size. Suture size 5-0 failed due to a S failure in 6/8 samples, PDX 4-0 failed in 2/8 samples and PDX 3-0 failed in only 1/8 samples. However, PDX 2-0 failed due to only T1 or T2 failures, with both failures being almost equally represented. No statistically significant differences in the load to failure between PDX 2-0, 3-0 and 4-0 were noted (P >0.05). The risk of suture failure increased with decreasing suture size diameter. PDX 2-0 and 3-0 can be used without reservation for the closure of ventral midline coeliotomy in cats. Although there was no statistically significant difference between PDX 2-0, 3-0 and 4-0, PDX 4-0 showed a higher probability for suture breakage and should be used only after careful consideration of the patient while clinical evaluation is pending. Pdx 5-0 cannot be recommended as a safe suture size for this type of surgical closure.

Embryonic Thyroid Hormone Insufficiency Causes Structural Anomalies in the Embryo of Domestic Chick, Gallus domesticus.

Thyroid hormone (TH) is essential for growth and development, yet its specific role during embryogenesis remains incompletely understood. This study investigates the impact of TH deficiency, induced by thiourea, a known inhibitor of thyroid peroxidase (TPO), on the development of domestic chicks. Thiourea was administered before thyroid gland formation, and its presence in treated embryos was confirmed through liquid chromatography-mass spectrometry. In silico docking revealed a strong interaction between thiourea and the CCP-like domain of TPO, which was corroborated by TPO activity assays showing reduced enzyme function. This reduction in enzyme activity led to lower embryonic TH levels and increased thyroid-stimulating hormone (TSH) secretion. Morphological analysis of newly hatched chicks revealed significant structural anomalies, particularly in lateral plate mesoderm-derived structures, including omphalocele, limb deformities, anophthalmia and craniofacial defects. Alcian blue and Alizarin red staining demonstrated reduced ossification in ribs and forelimbs, while histological analysis showed incomplete abdominal wall closure and abnormal vertebral column development. Haematological profiling of TH-deficient newly hatched chicks revealed significantly lower blood cell counts, highlighting TH's critical role in haematopoiesis. These findings emphasise the multifaceted role of TH in embryonic development, with potential implications for understanding congenital hypothyroidism and its developmental impacts, especially in regions with limited healthcare access.

Less Is More: The Role of Mesh in Microsurgical Breast Reconstruction with Abdominal Flaps.

The use of mesh to reinforce the abdominal wall after abdominal flap harvest has been reported to decrease the risk of bulging and herniation. However, the impact of the plane of mesh placement in relation to the anterior rectus sheath (vs. no mesh) on postoperative abdominal complications remains unclear. We retrospectively analyzed the length of stay and clinical outcomes in 158 female patients who underwent breast reconstruction with 250 free abdominal flaps. Group 1 consisted of patients who underwent polypropylene sublay-onlay ("sandwich") mesh placement (N = 70) versus polypropylene sublay-only mesh (group 2; N = 54) versus primary fascial repair without mesh (group 3; N = 34). Patient demographics and comorbidities were comparable between study groups, except for rates of neoadjuvant chemotherapy (group 1: 53% vs. group 2: 33% vs. group 3: 24% [p < 0.01]), postoperative follow-up in months (group 1: 21.5; group 2: 11.5; group 3: 7.6 [p < 0.01]), and length of stay in days (group 1: 4.9 vs. group 2: 4.4 vs. group 3: 3.3 [p < 0.01]). No differences were observed in breast flap and donor-site complications between study groups. Patients in group 3 required significantly lower oral morphine equivalent units postoperatively compared with those in groups 1 and 2 (group 1:185.5 vs. group 2: 79.7 vs. group 3: 71.6 [p < 0.01]). Abdominal donor-site closure without mesh was associated with a shorter length of stay and less narcotic intake without an increase in donor-site complications. These findings should be considered when deciding to place mesh for donor-site closure after abdominal flap harvest.

A retrospective study investigating the risk of graft loss in living donor liver transplant cases where size mismatching is predicted from graft-to-recipient weight ratio.

Living donor liver transplantation (LDLT) is vital for pediatric end-stage liver disease due to organ shortages. The graft-to-recipient weight ratio (GRWR) preoperatively measured predicts the outcomes of LDLT. We typically target between 0.8 and 3.0-4.0%, but the ideal GRWR remains controversial. We compared the outcomes of LDLT according to the GRWR to examine whether the criteria could be expanded while ensuring safety. We retrospectively reviewed 99 patients who underwent LDLT in our department by dividing them into three groups according to their GRWR: Group S, with GRWR values lower than the normal range (GRWR < 0.8%); Group M, with GRWR values in the normal range (GRWR ≥ 0.8 to < 3.5%); and Group L, with GRWR values above the normal range (GRWR ≥ 3.5%). In Groups S and L, 46.2 and 44.4% of patients underwent splenectomy and delayed abdominal wall closure, respectively. After these intraoperative adjustments, there were no significant differences between the groups in 5-year patient survival, 5-year graft survival, or the occurrence of post-transplantation thrombosis. When the GRWR is beyond the normal threshold, the risk of complications associated with graft size might be reduced by adjustments to provide appropriate portal blood flow and by delayed abdominal wall closure.

Modified Chevrel Technique: A Lifesaver for Surgeons.

Background and Objectives: Ventral hernias (VH) pose significant challenges for surgeons due to the risk of recurrence, complexities in aligning abdominal muscles, and selecting the most suitable layer for mesh augmentation. This study aims to evaluate the effectiveness of utilizing the anterior rectus fascia as a turnover flap in conjunction with onlay mesh reinforcement, a procedure known as the modified Chevrel technique (MCT). Materials and Methods: We conducted a retrospective analysis of patients who were operated on using MCT for abdominal hernias between January 2013 and December 2019. Data were extracted from our hospital's electronic database. Recurrence rates, as well as the rates of surgical site occurrences (SSO), surgical site infections (SSI), and surgical site occurrences requiring procedural intervention (SSOPI), were analyzed based on patients' comorbidities and demographic characteristics. Results: The median follow-up period was 42.9 months (range: 14-96), and the recurrence rate was 4% (n = 3). Among the recurrent cases, three patients had chronic obstructive pulmonary disease, representing a statistically significant association (p = 0.02). Although all patients with recurrence were obese, this association did not reach statistical significance (p > 0.05). The mean hospitalization duration was 17.6 days (range: 6-29). SSO, SSI, and SSOPI rates were 39 (52%), 12 (16%), and 32 (42%), respectively. Conclusions: Managing VH remains a surgical challenge, emphasizing the importance of achieving effective abdominal closure for both functional and cosmetic outcomes. MCT presents a relatively simple approach compared to techniques like transversus abdominis release (TAR) and anterior component separation (ACS), with acceptable rates of SSO, SSOPI, SSI, and recurrence.

Comparison of the Incidence of Surgical Site Infection in Abdominal Wound Closure: Antibiotic-Coated Polyglactin 910 Suture Versus Polyglactin Suture With Local Infiltration of Antibiotic Along the Incision Line.

Aim and objectives The purpose of this study is to compare the incidence of surgical site infection (SSI) rates in abdominal wound closure utilizing antibacterial-coated(triclosan-coated) suture material versus conventional suture material with subcutaneous antibacterial infiltration along the incision line. Materials and method This prospective and comparative (randomized, non-blinded clinical trial) was conducted at the Postgraduate Department of Surgery, Swaroop Rani Nehru Hospital, associated with Motilal Nehru Medical College, Prayagraj, India. The sample size was calculated to be one hundred. The patients in Group A underwent laparotomy using polyglactin 910 coated with triclosan. The patients in Group B underwent normal suture closure and local infiltration of broad-spectrum antibiotics (1 gram of ceftriaxone in 10 ml distilled water, along with the incision). Results There was no discernible difference between the various groups onpostoperativeday (POD) 14, 21, and 30. In Group A, 100.0% of individuals had healed wound status (POD 30). Group B had healed wound status among the 96.0% of members (POD 30). Twenty percent of the people in Group A had SSI whereas 38.0% of the participants in Group B had SSI. There was no discernible difference between the two groups regarding the distribution of culture (χ² = 7.741, p = 0.127). Conclusion Triclosan-coated sutures are more effective than subcutaneous antibiotic infiltration along the incision line in lowering the frequency of SSI during primary laparotomy wound closure.

Evaluation of preoperative rectus sheath block with bupivacaine for analgesia in cats undergoing ovariohysterectomy: a cadaveric and randomized clinical study

ObjectivePhase 1: to determine the feasibility of desensitizing ventral branches of spinal nerves within the rectus sheath using an ultrasound-guided rectus sheath block (USRSB). Phase 2: to determine the effect of preoperative USRSB on intraoperative responses to surgical stimulation and postoperative pain. Study designCadaveric study and prospective, randomized, blinded, parallel-arm clinical trial. AnimalsA group of five cat cadavers and 37 shelter-owned cats undergoing ovariohysterectomy. MethodsPhase 1: anatomical dissection was performed on one uninjected cadaver. Abdominal walls were dissected in four cadavers (eight hemiabdomens) following bilateral USRSB using 1:1 new methylene blue and 0.5% bupivacaine (0.8 mL kg–1 total). Phase 2: preoperative bilateral USRSB was performed with 0.8 mL kg–1 of 0.25% bupivacaine (RSB) or equivalent volume of 0.9% saline (CONTROL). Intraoperative systolic arterial blood pressure (SAP), heart rate (HR), respiratory rate (fR) and vaporizer setting (vap%) were recorded before skin incision, during celiotomy and abdominal wall closure. In recovery, cats were administered robenacoxib (2 mg kg–1; CONTROL) or 0.9% saline (0.1 mL kg–1; RSB) subcutaneously. Postoperative pain was evaluated for 6 hours using the Glasgow Composite Measure Pain Scale. ResultsPhase 1: spinal nerves T9–L3 were identified within the rectus sheath, and stained in 0%, 40%, 63%, 75%, 100%, 88%, 50% and 13% of hemiabdomens, respectively. Phase 2: 37 cats were included (RSB, n = 17; CONTROL, n = 20). Intraoperatively, SAP, HR and fR were not significantly different between groups. Vap% was significantly lower in RSB during celiotomy (p = 0.036) and closure (p = 0.044). Postoperatively, RSB cats were 5.3 times (95% CI 1.8–8.3) more likely to require rescue analgesia than CONTROL cats. Conclusions and clinical relevanceDuring surgery, USRSB with bupivacaine offered minor benefits and provided markedly less postoperative analgesia than robenacoxib, indicating that relying on USRSB provides insufficient postoperative analgesia for ovariohysterectomy in cats.

Impact of small-bite (5 mm) fascial closure on the incidence of incisional hernia following open colorectal cancer surgery: randomized clinical trial.

Incisional hernia is frequently observed after open colorectal cancer surgery, and should be considered a serious short- and long-term health issue. The present study evaluated the efficacy of small-bite abdominal closure in reducing the incidence of incisional hernia in this patient group. An RCT was conducted between June 2019 and June 2022. A total of 173 patients who underwent open colorectal cancer surgery were assigned randomly to one of two groups to undergo fascial closure with either small bites (87) or conventional bites (86). The incisional hernia rate was accepted as the primary outcome, and surgical-site infection as the secondary outcome. The incisional hernia rates at 1 year were 7 and 27% in the small- and conventional-bite groups respectively (P < 0.001). This rate increased to 9 and 31% at the end of the second year (P < 0.001). Surgical-site infections occurred in 18% of the small-bite group and 31% of the conventional-bite group (P = 0.03). Compared with the conventional-bite group, the small-bite group had higher suture/wound length ratios (mean(s.d.) 5.18(0.84) versus 3.67(0.57); P < 0.001) and a longer fascial closure time 14.1(4.64) versus 12.9(2.39) min; P = 0.03). Small-bite closure with 5-mm tissue bites placed 5 mm apart reduced the incidence of incisional hernia and surgical-site infection after open colorectal cancer surgery.

Managing the Open Abdomen: Selecting an Appropriate Treatment Strategy.

Significance: The laparotomy is a common surgical procedure with a wide range of indications. Ideally, once the goals of surgery were achieved, the incision edges could then be approximated and the abdomen primarily closed. However, in some circumstances, it may be impossible to achieve primary closure, and instead the abdomen is intentionally left open. This review discusses the indications and objectives for the open abdomen (OA), summarizes the most common techniques for temporary abdominal closure, and illustrates treatment algorithms grounded in the current recommendations from specialty experts. Recent Advances: Still a relatively young technique, multiple strategies, and technologies have emerged to manage the OA. So too have the recommendations evolved, based on updated classifications that take wound characteristics into account. Recent studies have also brought greater clarity on recommendations for managing infection and malnutrition to support improved clinical outcomes. Critical Issues: The status of the OA can change rapidly depending on the patient's condition, the wound quality, and many other factors. Thus, there is a significant need for comprehensive treatment strategies that can be adapted to these developing circumstances. Future Directions: Treatment recommendations should be continuously updated as new technologies are introduced and old techniques fall out of use.
