Introduction: Enterocolitis is a potentially fatal consequence of Hirschsprung’s disease, it is characterized by fever, abdominal pain, foul-smelling diarrhea, and sepsis. Most neonatal morbidity and mortality are caused by Hirschsprung-associated enterocolitis (HAEC). Harald Hirschsprung initially discovered Hirschsprung's related enterocolitis in the 19th century and included it in his iconic description of megacolon. Trisomy 21, illness, familial history, and prior bouts of HAEC are risk factors for the condition. (3, 4) According to Engun et al. patients who presented with a history of Hirschsprung's disease had a 35% incidence of HAEC, but those without such a history only had a 16% incidence. Similarly, HSD and trisomy 21 have a known association with 2. 9-8. 2% of HSD patients also having trisomy 21. This study aimed to evaluate HAEC as a postoperative complication in children who were admitted after pull-through surgery as regards the type of surgery, incidence, clinical presentation, sepsis workup, and management in Alexandria University Children’s Hospital. Materials and Methods: This retrospective study included 30 patients with Hirschsprung disease who developed post-operative Hirschsprung-associated enterocolitis and were scheduled for surgical intervention from January 2021 to 2022. Results: In the studied group, the most commonly used pull-through procedure was the Soave (53. 33%), followed by the Duhamel procedure (20%). Fewer subjects were operated using the Swenson and Rehbein methods, at 16. 67% and 10% respectively. Most of our studied patients (26 patients) presented with signs and symptoms of Grade I HAEC, while 3 patients with Grade II and 1 patient with Grade III. Conclusion: Post-operative HAEC is a serious complication and needs to proper management to save the child either conservative treatment, repeated anal dilatation or surgical intervention in severe cases.

Background: Despite contradictory reports regarding complication rates associated with various laparoscopictechniques, data specific to the Iranian population remain limited. In this study, we prospectively investigatedport-related complications in laparoscopic abdominal surgeries performed on individuals from the Iranianpopulation.Methods: This study was conducted as a prospective cohort at Imam Hossein Medical Center, Tehran, Iran,from 2021 to 2024. A total of 346 patients who were candidates for abdominal surgery using the laparoscopictechnique and referred to the tertiary hospital were included in the study based on the inclusion criteria.Demographic information about the patients, including age, gender, and underlying conditions, as well as datarelated to the surgery and complications associated with the port, were examined and recorded by the surgeonsfor six months following the surgery.Results: In this study, 346 patients were examined. The mean age of the patients was 44.34±11.80 years, withages ranging from 16 to 77 years. Among the patients, 206 (59.5%) were women, and 140 (40.5%) were men. Ofthe 346 patients who underwent surgery, 129 (37.3%) had a cholecystectomy, 117 (33.8%) underwent bariatricsurgery, and 71 (20.5%) had herniorrhaphy. Port-related complications were observed in 11 patients (3.2%),with port site infections diagnosed in 10 patients (2.9%). An incisional hernia was diagnosed in one patient(0.3%). There were no port site bleeding, omental injury, or other possible port-related complications.Conclusion: In this study, port-related complications among the Iranian population have been reportedfor comparison with other populations. The low complication rate of 3.2% aligns with global standards,underscoring the safety of laparoscopic procedures in well-equipped settings.

Background: Septoplasty is one of the most commonly performed operations with several complications.Purpose: To categorize and demonstrate the probability of the occurrence of septoplasty complications.Methods: Three hundred and twelve patients who underwent septoplasty in Loghman Hakim general hospital, Tehran, Iran, were followed up for 6 months and evaluated for probable post-operative complications.Results: The most common complication was remained deviation, which was observed in 26.2% of patients followed by synechiae and perforations. There was no case of serious and life threatening complications.Conclusion: Septoplasty has both aesthetic and functional complication. However, meticulous and careful surgery can prevent most of them.

Background: Brain tumors are rare and yet a significant cause of mortality and morbidity in adults. Surgical resection has been treatment of choice for brain tumors. Despite its effectiveness, surgical resection may cause various post-operatives complications such as infections, neurological deficits, and vascular damages that can lead to decrease in quality of life and survival rate and can impose great medical expenses. This study was aimed to assess related factors of medical and surgical complications after surgical brain tumors resection. Methods: This was a descriptive and retrospective study performed on patients that underwent brain surgical tumor resection at Rasoul Akram Hospital of Iran University of medical science in Tehran, 2016. Age, sex, extent of resection, pathology of tumor, post-operative symptoms and complications, duration of surgery, blood loss volume during surgery, and duration of admission were collected, and analyzed with SPSS. Results: Of 179 patients, 47. 5% (85) were male, and 52. 5% (94) were female. Mean patient age was 45. 8 years old, and mean admission duration was 4. 6 day before and 9. 7 day after surgery. The most common surgical complications were hydrocephalus (13. 4%) and ICH (9. 5%). The most common medical complication was electrolyte disorder (13. 4%). Mean surgery duration was 1 hour 40 min and mean blood loss during surgery was 542 ml. Conclusion: Based on our study, extent of brain resection was correlated with surgical and medical complications. Older age, longer duration of admission, and longer duration of surgery were correlated with medical complications, but it was not correlated with surgical complications. Older age was correlated with higher mortality rate. Blood loss volume during surgery had no correlation with surgical or medical complications.

Background and Aims: The purpose of this study was to evaluate the survival rate, mean bone loss and post operative complication of implants inserted in All-on-4 technique.Materials and Methods: The literature was searched using keywords angled implant, All-on-4, tilted implant and graftless technique in the last 10 years (2001 to 2011) and clinical trial article that evaluated survival rate and mean bone loss around axial and tilted implants in All-on-4 technique was selected and evaluated. A total of 73 articles were found by searching. After evaluation of titles and abstracts, finally 10 clinical trial, that were fully consistent with including criteria such as mean of bone loss and survival rate was selected and evaluated.Conclusion: Results showed that the survival rate (96-100%) and mean bone loss (0.34-1.9 mm) with All-on-4 technique in immediate loading is comparable with other implant support treatment plan. Comparison of implant survival and bone loss in axial and tilted implant in All-on-4 system showed that this treatment plan has consistent result with other conventional implant support prosthesis. Also, postoperative complication including fractures of the acrylic temporary prosthesis, detachment of the teeth, abutment or prosthesis screw loosening have been reported with All-on-4 technique.

Objective: Cochlear implantations have become a routinely performed and successful surgical intervention in both adults and children. The current article reports the complications encountered in various age groups of consecutive children who underwent implantation in our center.Methods: We performed a prospective analysis of all profoundly deaf children who underwent cochlear implantation from March 2006 to July 2009 at Baqhiyatallah Cochlear Implantation Center. All patients were younger than 5 years old at the time of implantation.Findings: The minor complications occurred in 49 (18.7%) cases, The most common postoperative complications were temporary facial weakness detected in 15 cases (5.7%) all of which were reversible. Magnet wound was observed in 14 (5.3%) patients, keloid formation in 10 (3.8%), wound infection in 2 (0.8%), otitis media in 5 (2%), and electrode movement, meningitis, vertigo, Laryngospasm each in 1 (0.4%) case was detected among our patients.Conclusion: Cochlear implantation in children continues to be reliable and safe in experienced hands, with a low percentage of severe complications as long as the patient is monitored closely.

Diabetes mellitus is a systemic disease that involves multiple organs. Several documented studies indicated that prevalence of gallstone in diabetics is higher-than nondiabetics. Thus, rate of acute cholecystitis and cholecystectomy should be higher in these patients. Some studies have shown that the risk of postoperative complications is higher in the diabetics. This cross-sectional stutfy has been done from 1374 to 1377 in two university hospitals (Bahonar and Kerman-Darman) of Kerman. The study is conducted on 227 sequential patients with cholecystitis that were candidates for cholecystectomy within 72 hours of diagnosis. After preliminary therapy and Para clinic study, including fasting blood sugar (FBS) measurement, upper midline laparotomy was performed-following induction of general balanced anesthesia. Stage of the disease was registered during the operation. The subjects were followed up to 30 days for detection of postoperative complications. There were 34 (15%) diabetics (5 type-1 and 28 type-2 diabetics) with age of 62.6±11.9 years, and 193 (85%) nondiabetic patients aged 54.4±15.8 years old. Therefore the age of diabetics were higher than that of nondiabetics (P=0.0008). FBS of diabetic and nondiabetic groups were 189.12±53.64 mg/dl and 91.44±15.15 mg/dl respectively (P=0.0001). As for as progression of the disease, 25(23.5%) of diabetics and 90 (74%) of non diabetics had a higher stages of cholecystitis (P<0.05). Postoperative complications were encountered in 15 (38.4%) cases - of diabetic. And 21 (10.5%) cases of nondiabetic groups (P<0.001, OR=5.33, X2=19.86). It seems that increased prevalence of postoperative complications in diabetic patients is due to more advanced stages of their, disease at the time of diagnosis. However systemic changes due to aging in diabetic patients should also be considered.

Introduction & Objective: Wound dehiscence (WD) is a serious complication in abdominal surgeries, which increases mortality and morbidity rates. WD is a multi factorial problem. The aim of this study is exploring the known risk factors of WD complication between cases and control group.Materials & Methods: In this case-control study, 132 cases undergoing surgery’s were investigated during ten years in Alzahra hospital of Rasht city.44 patients with and 88 paients without WD complication were entered in study. Factors such as age, history of cancer, anemia, diabetes mellitus (DM), sepsis, chemotherapy and radiotherapy, steroid therapy and other factors like surgeon type, incision type, type of surgery and its duration were recorded and compared in two groups.Results: Among cases that were studied, 44 were diagnosed with the WD complication and 88 people were selected as control group, and we compared risk factors among these people. Among reocorded data, history of having anemia, DM, emergency operation, increased surgical time and low experience of surgeon was identified as risk factor based on statistical analysis (P<0.05).Conclusions: Controlling and correction of identified risk factors (such as DM or anemia), which can be modifie result in decreasing the incidence of WD post operatively.

Introduction: Exchange transfusion (ET) is an effective mode of therapy in the treatment of hyperbilirubinemia, but is associated with some complications in 5-10% of the patients, especially in preterm newborns. The most important complications following exchange transfusion are: Acidosis, thrombocytopenia, hypocalcemia, hyponatremia, hypoglycemia and transmitting infectious agents. This study aims to determine some complications of exchange transfusion in neonatal hyperbilirueinemia in NICU of 22 Bahman 22nd Hospital in order to promote its safety and efficacy.Materials and Methods: In this study neonates with undergone exchange transfusion due to hyperbilirubinemia were evaluated over a period of 36 months in NICU of 22 Bahman 22nd Hospital from July 2005 to July 2008 in Mashhad. The questionnaires were completed according to the by patients’ data. The data were then and analyzed for statistical results.Results : Of the 28 neonates who entered the study, 3 required more than one ET. Complication of ET occurred in 24 neonates (85.7%).The most common complications were being metabolic acidosis (67.9%) and thrombocytopenia (50%).Conclusion: In order to avoid complications following exchange transfusion, it should be emphasized to have laboratory tests done. For instance, tests of platelet count and arterial blood gases are needed so that in cases of complications, the available information can facilitate the treatment. They can be treated on time.
