Zinc oxide loaded chitosan-elastin-sodium alginate nanocomposite gel using freeze gelation for enhanced adipose stem cell proliferation and antibacterial properties.

Hydrogels have been the material of choice for regenerative medicine applications due to their biocompatibility that can facilitate cellular attachment and proliferation. The present study aimed at constructing a porous hydrogel composite scaffold (chitosan, sodium alginate and elastin) for the repair of chronic skin wounds. Chitosan-based hydrogel incorporating varying concentrations of zinc oxide nanoparticles i.e. ZnO-NPs (0, 0.001, 0.01, 0.1 and 1 % w/w) as the antimicrobial agent tested against Escherichia coli (E.coli) and Staphylococcus aureus (S. aureus) exhibited good antibacterial activities. ZnO-NPs were characterized by UV visible spectroscopy, Scanning electron microscopy (SEM) analysis, Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analysis. Fabricated gels were characterized by SEM analysis, FTIR, XRD, swelling ratio, degradation behavior and controlled release kinetics of ZnO-NPs. In vitro cytocompatibility of the composite was investigated using human adipose stem cells (ADSCs) by MTT and lactate dehydrogenase (LDH) assay, further assessed by SEM analysis and PKH26 staining. The SEM and XRD analysis confirmed the successful loading of ZnO-NPs into these scaffolds. Fluorescence PKH26 stained images and SEM analysis of ADSCs seeded scaffolds revealed biocompatible nature. The findings suggested that the developed composite gels have potential clinically for tissue engineering and chronic wound treatment.

Early Active Mobilization Vs Immobilization Following Modified Kessler Repair Of Extrinsic Extensor Tendons In Zone V TO VII.

BACKGROUND: The long-disputed issue of rehabilitation of extensor tendon repairs in zones V-VII has been treated with either complete immobilization or mobilization within the constraints of splint. In recent times, most authors have preferred some mobilization. Many studies have shown good results with early mobilization techniques; however, these studies have limitations. Most of these are retrospective observations. Some prospective studies are without proper controls. This study was conductive to compare the functional outcome of early active mobilization versus immobilization following repair of extensor tendons in zone V-VII. METHODS: Functional outcome was determined by total active motion, pain and complications during rehabilitation. Total active motion (TAM) was graded by scores of the American Society for Surgery of Hand as TAM=total active flexion (MCP+PIP+DIP)-total extension deficit (MCP+PIP+DIP). A randomized control trial was conducted including 50 subjects of with extensor tendon injury exclusively in zone V-VII. Patients were divided randomly in two groups. All extensor tendon repairs (zone V to VII) were performed with modified Kessler's method. The pain and TAM was assessed during all visits in both groups except TAM in group B that was assessed after four weeks. RESULTS: We found that outcome of 12% cases in Group A as excellent and no patient fell in category of fair results. While, in comparison, there was no case of excellent result in Group B. 4% cases showed fair results that were treated with immobilization. The pain score at the end of treatment, i.e., at 12 weeks were same in both the groups but, generally the score remained higher in group of EAM. There was significant difference in adhesion formation that was more in patients of immobilization group. The overall suture dehiscence was insignificant and was only 8% in each group. CONCLUSIONS: EAM has better outcome in terms of pain and range of motion.

Extended Islanded Reverse Sural Artery flap for Staged Reconstruction of Foot Defects Proximal to Toes.

Obective:To assess the outcome of extended delayed reverse sural artery flap for reconstruction of foot defects proximal to toes in terms of flap survival, complication and extended area. STUDY DESIGN: Case series. PLACE AND DURATION OF STUDY: Jinnah Burn and Reconstructive Surgery Centre, Lahore, from February 2015 to April 2017. METHODOLOGY: Cases who underwent delayed sural artery flap were inducted. Preoperative hand-held doppler was done to confirm the location of perforator. Two suitable perforators were chosen to raise the extended flap by crossing the proximal limit in all cases. The pedicle was kept minimum 3 cm wide and perfusion was assessed. Flap was delayed for one week and vaccum-assisted closure (VAC) dressing was applied over wound. The second surgery was performed after one week. Proximal perforator was clamped and ligated after checking adequate perfusion of flap. Flap was insetted into defect. RESULTS: Thirty-two patients were reconstructed with delayed reverse sural artery flap. The mean age of the patients was 26.5 12.2 years. Twenty-four (75%) patients were males and 8 (25%) were females. Twenty-two (68.7%) cases were degloving wounds after road traffic accidents (RTA), 6 (18.7%) were diabetic foot wounds, 4 (12.5%) sustained injury after falling from height and 7 (21.8%) patients had fracture of metatarsals. Twenty-eight flaps were transferred after one week delay, and only in 4 cases, flap were transferred after two weeks. All flaps survived completely. Complications of infection noted in 3 (9.3%) flaps, 3 (9.3%) flaps showed tip necrosis, 2 (6.2%) flaps undergone epidermolysis and only 2 (6.2%) showed venous congestion. CONCLUSION: Delayed islanded reverse sural artery perforator flap is a reliable and versatile option for resurfacing soft tissue defects of lower limb proximal to the toes with lesser complications and extended coverage area.

Quantification and Further Refinements of Dorsal Metacarpal Artery Perforator Flap for Reconstruction of Wounds of Fingers upto Distal Interphalangeal Joints.

OBJECTIVE: To assess the outcome of dorsal metacarpal artery perforator flap for coverage of finger defects extending upto distal interphalangeal joint (DIPJ). STUDY DESIGN: Case series. PLACE AND DURATION OF STUDY: Jinnah Burn and Reconstructive Surgery Centre, Lahore, from March 2015 to May 2017. METHODOLOGY: Our study was carried out in two parts. 1st part of study was to measure average flap length in our population. Five hundred cases were enrolled to measure flap length, from pivot point of the flap to the distal border of extensor retinaculum. This length was traced to fingers to determine its coverage area. This was followed by clinical study in 35 cases. All patients with wounds over dorsal surface of fingers upto distal interphalangeal joint and volar surface of fingers upto mid of middle phalanx, single or multiple finger defects with exposed tendon joints or bones were included in the study. Patients with history of trauma to the dorsum of hand, metacarpal head or neck fracture and patients with history of diabetes or peripheral vascular disease were excluded. RESULTS: Flap length decreased from radial to ulnar side of hand. Average length of flap based on the second metacarpal artery was 7cm while of the third was 6.6 cm and the fourth was 6.1 cm. This flap length covered upto mid of middle phalanx in border digits while upto PIPJ in central digits. This data was confirmed in 35 patients in which 36 flaps were raised to cover finger defects. Thirty-four flaps survived completely while tip necrosis was seen in 2 cases. CONCLUSION: The dorsal metacarpal artery perforator flap is a thin, pliable flap, which has minimal donor-site morbidity. It can reliably cover soft tissue defects of dorsum of fingers upto mid of middle phalanx in border digits and upto PIPJ in central digits.

Hemisoleus muscle flap, a better option for coverage of open fractures involving middle third of tibia.

BACKGROUND: Local reconstructive options for middle third of leg make good use of Soleus muscle flap. Soleus being the prime ankle planter flexor and stabiliser of the ankle in ambulation cannot be sacrificed without significant morbidity. Soleus is a bipennate muscle with independent blood supply of each half. Using one half retains its important function, increases arc of rotation, and makes it easy to orientate for coverage of defect of any shape thus obviating the need for use of whole Soleus muscle flap. Due to this geometrical advantage, it is a superior option than the whole Soleus. We conducted a study to evaluate the reliability of the medial hemisoleus muscle flap for coverage of middle third tibial defects. METHODS: This descriptive study was conducted at department of plastic surgery, Jinnah Hospital, Lahore from August 2008 to May 2009. Ten patients with middle third tibial defects were included in the study. All the patients were provided soft tissue coverage with proximally based medial hemisoleus muscle flap with split thickness skin graft on it. RESULTS: All the flaps survived with primary healing of the wound except one patient who developed wound infection which settled after wound drainage and irrigation. CONCLUSION: Hemisoleus muscle flap is a valuable local option for soft tissue coverage of middle third of lower leg. It does not sacrifice the whole function of the Soleus muscle. Due to its longer arc of rotation, this flap can cover the defects of different size and shape in middle third of leg.

Scalp as a donor site for split thickness skin grafts.

BACKGROUND: Use of scalp as a donor site was reported for the first time in 1964. Since then, authors have described scalp as a donor site, which heals rapidly and re-growth of hair conceals the donor site. This study was aimed at evaluation of scalp as donor site by calculating the healing time, and frequency of post-operative complications. METHODS: This was a descriptive study and was conducted at Plastic Surgery Department Jinnah Hospital, Lahore, from October, 2006 to December 2007. Thirty patients requiring split skin grafting for small to moderate sized defects (requiring up to 4 sheets) were included in this study. After taking informed consent skin graft were taken from the scalp using Zimmer Electric Dermatome. Donor site was covered with occlusive dressing. Donor site healing time and complications were recorded. Patients having scalp lesions were excluded from the study. RESULTS: All the patients in this study achieved healing of the donor site. None of them required grafting. 26 (86.67%) patients achieved healing by 6th post-op day 3 (10.0%) patients achieved healing by 10th post-op day and the remaining 1 (3.33%) patients achieved healing by 20 days. Complications noted were folliculitis in 2 patients and scab formation in 1 patient. Alopecia, hair transplant to recipient site and hypertrophic scarring was not encountered in our study. Patients were discharged by 6th post operative day and complications were managed on outpatient basis. Overall patients' compliance and satisfaction was excellent. CONCLUSION: scalp is an excellent donor site for taking split skin graft. It has shown to be very useful in terms of quick healing, convenient post-op care and negligible complications. It should be given preference when donor site for taking skin graft is to be selected.

Choledochoduodenostomy: reappraisal in the laparoscopic era.

BACKGROUND: With the advent of interventional endoscopic procedures and with growing experience of laparoscopic surgery, the indications for open biliary procedures have become limited. This prospective study reviews the indications of open choledochoduodenostomy for benign biliary diseases and presents the short-term and long-term outcomes of this procedure in the present minimally invasive surgical era. METHODS: Side-to-side choledochoduodenostomy was carried out for various benign obstructive pathologies of the biliary tract. The various parameters recorded were the demographic data, indications for surgery, early and late complications and the long-term outcome of the procedure. RESULTS: Results of choledochoduodenostomy on 54 consecutive patients over a 9-year period are presented. The mean age was 49.7 years with a male to female ratio of 1:2.6. Thirty (55.5%) patients presented with obstructive jaundice and 42.6% had cholangitis. Overall hospital morbidity was 13% with zero mortality. After a mean follow up of 7.8 years, 96.3% patients had 'good' or 'fair' and 3.7% experienced 'poor' results. No recurrent disease or biliary malignancy was observed. CONCLUSION: Open biliary drainage procedures may still be indicated in select patients where the facility or expertise for minimally invasive biliary procedures is not available. Choledochoduodenostomy remains an effective biliary drainage procedure with acceptable morbidity and mortality, especially in the high-risk and elderly population. The procedure should be regarded as an essential in the general surgical knowledge and training.

Gastrointestinal tract bleeding in intellectually disabled adults.

BACKGROUND: Gastrointestinal (GI) tract bleeding in intellectually disabled (ID) individuals presents peculiar diagnostic and management difficulties. This study details the experience of a tertiary referral teaching hospital in Central Saudi Arabia in the management of GI bleeding necessitating admission in ID adults. PATIENTS AND METHODS: Prospective collection of data was taken on consecutive ID adults admitted for GI bleeding from January 2000 through December 2004. Demographic details, clinical presentation, diagnosis, associated physical and neurologic disabilities, etiology of bleeding and treatment outcome were analyzed. RESULTS: Thirty-nine ID adults accounted for 44 admissions during the period under review. Twenty-six (66.7%) patients were admitted with upper, and 13 (33.3%) for lower GI bleeding. Reflux esophagitis (57.7%) remained the most common cause of upper GI bleeding. Five out of 26 patients with upper and 6 of 13 with lower GI bleeding needed operative treatment. Various congenital anomalies or malformations were observed frequently associated with lower GI bleeding. CONCLUSIONS: Bleeding GERD remained the most common etiology of upper GI bleeding necessitating admission. Endoscopy is the mainstay in diagnosis and initial management of ID patients. Continued surveillance endoscopy is recommended for early diagnosis of Barrett changes. Bleeding from developmental malformations may have association with intellectual disability.

Adenocarcinoma of urachal cyst associated with pseudomyxoma peritonei masquerading as abdominal tuberculosis: A case report and review of literature.

A case of 14-year-old girl is reported who presented with features of tuberculous subacute intestinal obstruction. Exploratory laparotomy revealed a urachal cyst associated with pseudomyxoma peritonei (PMP). Histopathology confirmed a moderately differentiated mucin secreting adenocarcinoma of urachal cyst associated with PMP. The adenocarcinoma of urachal cyst associated with PMP is further reviewed.

Suture versus mesh repair for incisional hernia.

OBJECTIVE: To compare suture with mesh repair, for incisional hernia in terms of early and late outcomes. METHODS: We reviewed the records of all the patients who presented with primary or recurrent incisional hernia in the Department of General Surgery, Riyadh Medical Complex, Riyadh, Kingdom of Saudi Arabia, from January 2000 to December 2004. We divided patients, who underwent repair, in 2 groups: Group A (suture repair) and Group B (mesh repair). The information recorded for both groups included gender, age, associated systemic illness, site of hernia, initial surgery, number and type of previous hernia repairs, size of hernial defect, techniques of repair, and hospital stay. The principal early and late outcome measures studied were septic complications and recurrence. RESULTS: A total of 123 patients qualified for the study, 72 in group A and 51 in group B. Wound infection was 5.5% in group A versus 3.9% in group B (p=0.51). Follow up ranged between 6-58 months (mean 37.5 months) for both groups. Fifteen patients (20.8%) developed recurrence in group A, while the recurrence rate in group B was only 5.8% (p=0.04). CONCLUSION: Mesh repair resulted in a lower recurrence rate, and is not associated with increased incidence of wound complications compared with suture repair.

Transabdominal gastro-esophageal devascularization and esophageal transection for bleeding esophageal varices after failed injection sclerotherapy: long-term follow-up report.

BACKGROUND: Management of continued bleeding from esophageal varices despite adequate injection sclerotherapy remains one of the medical and surgical dilemmas. Transabdominal gastroesophageal devascularization and esophageal transection (TGDET) is considered an effective and safe procedure for such patients. AIM: This study aimed at presenting continued evaluation of TGDET. Various problems influencing the early outcome are discussed, and long-term outcome is analyzed. DESIGN: This was a prospective clinical descriptive study. METHODS: Prospective data was collected on 142 consecutive patients managed by one group of surgeons over a 5 year-period and 15 years follow-up after failed injection sclerotherapy for variceal bleeding. Evaluation was made in terms of effectiveness in controlling the acute bleeding, postoperative morbidity and mortality, recurrent bleeding, encephalopathy, and long-term survival. RESULTS: There were 133 men and 9 women. Mean age was 41.8 years. Etiology of portal hypertension was bilharziasis in 54.9% and posthepatitic in 14.8%. Child-Pugh grading on admission was A: 47.2%, B: 28.8%, and C: 14%. Hemorrhage was controlled in all cases. Clinical leak was observed in 5.6%, portal vein thrombosis in 6.3%, and staple line erosion in 2.1% of cases. No patient developed encephalopathy. In-hospital mortality was 12.7%. Complete eradication of varices was observed in 70.6% patients. Recurrent variceal bleeding was noticed in 6.9% of cases. Actuarial 15-year survival for Child-Pugh A patients was 44%, B was 22.5%, and none for C. CONCLUSION: TGDET remains a safe and effective procedure after failure of sclerotherapy when other alternatives are either not indicated or not available.

Surgery for acute abdominal conditions in intellectually-disabled adults.

BACKGROUND: Intellectually-disabled patients with acute abdominal conditions are susceptible to late diagnosis and adverse outcome due to impaired communication, altered behaviour, neurological impairment, associated congenital anomalies, variable reaction to pain and drugs and various difficulties in perioperative management. The present study aims to present the experience of surgery for acute abdominal conditions in intellectually-disabled patients. Various difficulties encountered during the management are highlighted and measures to overcome these problems are discussed. METHODS: A prospective descriptive population study was performed through the prospective collection of data on consecutive intellectually-disabled adults operated for acute abdominal conditions over a 5-year period. Study parameters included demographic details, clinical presentation, diagnostic modalities, operative findings and outcome in terms of morbidity and mortality. RESULTS: Of 19 men and three women with a mean age of 28.3 years, anorexia, vomiting, and increasing abdominal distension were the most common presenting features. History of pica was available in 36.4% of patients. Intestinal obstruction, acute appendicitis, volvulus and pseudo-obstruction of the colon were the most frequently encountered conditions. Postoperative morbidity and mortality were 33 and 23%, respectively. CONCLUSION: Intellectually-disabled patients demand particular clinical expertise owing to various difficulties inherent to their mental and physical disabilities. Short history, anorexia, vomiting and abdominal distension should make the clinician aware of the possibility of an acute abdominal condition. History of pica should be considered a serious clinical correlate. A high index of clinical suspicion, intensive perioperative care and low threshold for an early operation are recommended to reduce the higher morbidity and mortality figures.

Spectrum of general surgical problems in the developmentally disabled adults.

OBJECTIVE: This study highlights the spectrum of general surgical problems necessitating admission on intellectually disabled adult patients. Problems encountered in the management and the ways to overcome various difficulties are highlighted. METHODS: Prospective collection of data on 63 consecutive developmentally disabled adult patients admitted to the Department of General Surgery, Riyadh Medical Complex (RMC), Riyadh, Kingdom of Saudi Arabia for various indications from January 2000 through December 2004. Demographic details, clinical presentation, diagnostic modalities, associated physical and neurological disabilities, coexisting medical condition, treatment options, morbidity and mortality were analyzed. Various difficulties encountered during the management and mean to overcome these problems are addressed. RESULTS: Sixty-three patients accounted for 71 admissions. Mean age was 26.7 years with a male preponderance (4.25:1). Fifty-four patients were admitted for various emergency conditions. History of pica could be obtained in 33% of the cases. Twenty-seven patients were admitted for acute abdomen. Volvulus of the colon (22.2%) and pseudo-obstruction (18.5%) were the most common causes of acute abdomen. Twenty-one patients were admitted with upper gastrointestinal bleeding. Reflux esophagitis was the most common cause of bleeding (62%). Overall morbidity was 41% for emergency admissions and 22% for elective surgery. Hospital mortality was 21.4% for emergency surgery. There was no death in elective cases. CONCLUSION: Developmentally disabled patients comprise a special class of patients with peculiar management problems. The treating clinician should be aware of various unexpected conditions not found as frequently in the normal patient population. Apparent lack of pain does not exclude an acute emergency. Possible surgical condition should be suspected if there is vomiting, abdominal distension, fever, increased irritability of recent onset. Male gender and history of pica are added risk factors.

Outcome of surgery for parotid tumours: 5-year experience of a general surgical unit in a teaching hospital.

BACKGROUND: Most of the recent reports on the surgical management of parotid gland disorders come from specialist divisions of otolaryngology, head and neck, or faciomaxillary surgery. The aim of the present study was to evaluate the outcome of surgery for parotid tumours in a general surgical unit of a teaching hospital. METHOD: A prospective clinicopathological study was undertaken over a 5-year period for consecutive patients operated on for parotid gland tumours in the King Saud University Unit of Riyadh Medical Complex. Parameters analyzed were demographic details, clinical presentation, diagnostic work-up, type of surgery, and outcome in terms of early and late morbidity. RESULTS: Thirty seven parotid operations were performed on 36 consecutive patients. All patients presented with parotid gland swelling. Mean age was 51.6 years with a male preponderance. Fine-needle aspiration diagnosed the pathology in 33 out of 37 lesions. Pleomorphic adenoma was the commonest pathology observed in 24 patients (64.9%). Warthin's tumour was more common among male patients and was the only pathology with bilateral involvement. Malignant tumour was found in five patients (13.5%). Superficial conservative parotidectomy was the most frequently performed operation (84%). Overall postoperative morbidity was 13.5%. Transient facial nerve palsy was observed in seven cases (19%). There was no recurrence identified in patients with benign diseases during the mean follow up of 38.5 months. CONCLUSION: Parotid gland surgery can still be performed in a general surgery unit with comparable outcome. However, the operation should be performed in units with special interest and experience in surgery for parotid gland disorders.

Mirizzi syndrome: ten years experience from a teaching hospital in Riyadh.

OBJECTIVE: Mirizzi syndrome (MS) is an uncommon presentation of cholelithiasis. This study aims to find the incidence and analyze the outcome of management of this condition at Riyadh Medical Complex (RMC) with particular reference to diagnostic methods and outcome of surgical treatment. METHODS: Retrospective study on 17 consecutive patients of MS diagnosed and managed at RMC over ten year period. The records were reviewed for demography, clinical presentation, diagnostic methods, operative procedures, postoperative complication and follow up. RESULTS: The incidence of MS syndrome was 0.7% of 2415 cholecystectomies. There was preponderance of Type I variety (58.8%). Ultrasonography was able to diagnose 82% cases. ERCP suggested the diagnosis in all cases and helped further in classifying and management of these patients. All Type I cases were managed with partial cholecystectomy, two underwent laparoscopic surgery. Three Type II patients were managed by partial cholecystectomy alone. Three patients with Type III variety had choledochoplasty whereas one remaining patient with Type IV variety underwent hepatico-jejunostomy. All patients had complete recovery with 17.6% procedure-related morbidity and no hospital mortality. All patients are doing well over a mean follow up 6.5 years. CONCLUSION: Preoperative diagnosis of Mirizzi syndrome by ultrasound and ERCP is essential to prevent serious complications during surgery. Partial cholecystectomy is an adequate procedure for Types I & II MS. Choledochoplasty provides an effective surgical repair in Type III cases. Although laparoscopic cholecystectomy in MS may be hazardous, it may still be tried in preoperatively diagnosed type I cases, provided the surgeon is experienced and keeps a low threshold for conversion open surgery.

Acute small bowel obstruction due to bilharziasis.

Schistosomiasis remains a major world health problem. The disease presents with protean manifestations in the endemic areas. Small bowel schistosomiasis leading to acute intestinal obstruction is an extremely rare clinical presentation. The disease may mimic peritoneal tuberculosis or carcinomatosis intra-operatively. Small bowel bilharziasis leading to obstruction has not been reported in the recent indexed English literature. This report describes a 50-year-old Yemeni male presenting with acute small bowel obstruction due to schistosomiasis. We review the pathological changes in the intestine following schistosomal infection and discuss diagnosis and treatment. We emphasize the importance of histopathology on all surgical specimens.

Castleman disease presenting as obstructive jaundice.

A 48-year-old Saudi male was admitted with features of obstructive jaundice. Endoscopic retrograde cholangiopancreatography showed stricture in distal common bile duct CBD. Computed tomography scan revealed lymphadenopathy along CBD and in porta hepatis. Cholangiocarcinoma, lymphoma or metastatic deposits were suspected but no definite preoperative diagnosis could be established. Laparotomy disclosed lymph node enlargement in porta hepatis and along the CBD and lesser curvature of the stomach. Triple bypass procedure was performed to relieve the obstruction. Pathological examination of the lymph nodes showed Castleman disease of hyaline vascular type.

Primary actinomycosis of the abdominal wall.

Primary actinomycosis of the abdominal wall is a rare clinical entity. Only 7 adequately described cases have been reported in the English literature. We report a case of isolated abdominal wall actinomycosis involving the left lower quadrant of the abdominal wall in a 32-year-old diabetic male. The diagnosis was confirmed by histopathological examination. Surgical drainage of the abscess followed by long-term administration of penicillin resulted in cure. The clinicopathological spectrum of actinomycosis is reviewed and isolated involvement of the abdominal wall is characterized in light of the knowledge acquired from the available literature on this rare clinical presentation. The significance of obtaining tissues for culture and histopathology in all inflammatory lesions is emphasized.

Role of ultrasonography, computed tomography and diagnostic peritoneal lavage in abdominal blunt trauma.

OBJECTIVE: To compare the diagnostic accuracy of diagnostic peritoneal lavage (DPL), ultrasonography and computed tomography in the management of blunt abdominal trauma. METHODS: A retrospective review of the charts of 233 patients with blunt abdominal trauma necessitating admission to Riyadh Medical Complex, Riyadh, Kingdom of Saudi Arabia was carried out over a 2 year period (January 2000 to December 2001). The diagnostic yields of DPL, ultrasound and computed tomography were analyzed. The results were compared with findings on subsequent laparotomy or ultimate outcome, which continued in hospital observation and conservative management. RESULTS: Mean age was 23 years and 79% patients were male. Road traffic accident remained the most common cause (70%) and 56% patients had multisystem injuries. The sensitivity for DPL, ultrasound and computed tomography scans was found to be 98%, 96% and 98% with an overall accuracy rate of 92%, 95% and 99%. Diagnostic peritoneal lavage showed false positive results with retroperitoneal injuries and missed one small bowel injury and a pancreatic injury, and resulted in one catheter related bowel injury. Computed tomography scan was able to grade, quantify and localize the injury and helped in devising a successful management plan in 76.5% cases. CONCLUSION: Diagnostic peritoneal lavage is a promising bedside investigation, but is invasive with low accuracy for retroperitoneal injuries and high probability of nontherapeutic laparotomy with false positive results. The high sensitivity and accuracy rates of computed tomography justify its use in quantifying and estimating the grade of injury in order to select the appropriate management of trauma victims. Computed tomography is recommended as the initial investigation of choice in hemodynamically stable patients with blunt abdominal trauma.
