The Effect of Using In Vitro Fertilization (IVF) on Increasing the Prevalence of Craniosynostosis.

BACKGROUND: Craniosynostosis, a malformation caused by premature closure of one or more cranial sutures, is a rare congenital disability usually of unknown cause; however, it is often associated with assisted reproductive technology. Given the increasing prevalence of craniosynostosis and the use of the in vitro fertilization (IVF) method, the authors evaluated the association between IVF and the prevalence of craniosynostosis. METHODS: This retrospective study reviewed records of patients with nonsyndromic craniosynostosis who underwent surgery in Mofid Hospital, a tertiary children's hospital affiliated to Shahid Beheshti University of Medical Sciences, between 2010 and 2019. RESULTS: A total of 200 patients aged one month to 7 years old, were evaluated. Out of 200 patients, 43% were plagiocephalic, 39% trigonocephalic, 8.5% scaphocephalic, 8% brachiocephalic, and 1.5% were mixed. Nine (4.5%) patients had received clomiphene citrate. Eight (4%) mothers had become pregnant under IVF, and they all had used clomiphene citrate for ovulation stimulation. No use of artificial insemination was reported. Of the eight patients whose mother had become pregnant through IVF, three were trigonocephalic, and five were plagiocephalic. CONCLUSIONS: Without a control group, we are not able report the statistical results confirming or denying a link between craniosynostosis and infertility treatment. However, 4% prevalence of IVF use among craniosynostosis patients is significant. Further studies with a broader statistical community are suggested in this regard.

Acute Activation of α7-Nicotinic Receptors by Nicotine Improves Rodent Skin Flap Survival Through Nitrergic System.

BACKGROUND: Recent reports have identified angiogenic, anti-inflammatory, and antioxidant properties of acute treatment with nicotine via activation of nicotinic acetylcholine receptors (nAChRs). In addition, the nitric oxide (NO) pathway is involved in ischemic reperfusion injuries. OBJECTIVES: We investigated the effects of acute pretreatment with nicotine in a rat model of random-pattern skin flap and the potential role of the NO pathway. METHODS: The Sprague-Dawley rats received increasing doses of (-)-nicotine (0.5, 1, 1.5, 2, and 3 mg/kg) before the procedure. Dorsal skin flaps with caudal pedicles were elevated at the midline, and flap survival was evaluated 7 days after surgery. In addition, animals received an α7-nAChR antagonist, methyllycaconitine, with nicotine. Quantitative reverse transcription polymerase chain reaction was also applied to measure the dermal expression of α7-nAChR. Next, a nonselective NO synthase inhibitor, N-nitro-L-arginine methyl ester hydrochloride; a selective inducible NO synthase inhibitor, aminoguanidine; and an NO precursor, L-arginine, were administered with nicotine. RESULTS: Nicotine at doses of 1, 1.5, and 2 mg/kg significantly increased flap survival, whereas the protective effects of nicotine disappeared at higher doses. Methyllycaconitine completely reversed the protective effects of nicotine and the elevated cutaneous expression of α7-nAChR in nicotine-pretreated rats. In addition, systemic administration of N-nitro-L-arginine methyl ester hydrochloride or aminoguanidine with an effective dose of nicotine caused a significant decrease in flap survival. Conversely, coinjection of a subeffective dose of L-arginine with the subeffective dose of nicotine significantly boosted its protective effects. CONCLUSIONS: Acute pretreatment with nicotine by stimulating the expression and activation of cutaneous α7-nAChR improves skin flap survival, which is partially mediated through modulation of the NO pathway.

Introducing A Family With Tens of Rare Craniofacial Clefts.

BACKGROUND: Craniofacial clefts are one of the rarest congenital malformations. When it comes to genetic inheritance patterns of craniofacial clefts, there are few studies on this subject due to the rarity and sporadic nature. In this study an extended family whose members have multiple craniofacial clefts has been introduced. METHODS: The authors haphazardly found a family whose members have craniofacial clefts, either Tessier no. 0 or both Tessier nos. 0 and 14, and, consequently, they were categorized into 3 groups based on the severity of clefts. RESULTS: Forty-two craniofacial clefts were noticed within the family. Twenty-two (52.3%) of patients were females and 20 (47.6%) were males. Twenty-three (54.8%) members had isolated Tessier no. 0 cleft, whereas 19 (45.2%) members had both Tessier nos. 0 and 14. Of all 42 patients, 18 (42.8%), 3 (7.1%), and 21 (50%) patients had severe, intermediate, and mild clefts, respectively. CONCLUSION: The present study reveals that in some patients genetic background is likely to be the cause of clefts.

Role of Autologous Fat Injection in Neglected Patients With Anterior Plagiocephaly.

Anterior plagiocephaly is a type of non-syndromic craniosynostosis requiring surgery. In this study, the authors have presented 15 neglected patients with anterior plagiocephaly. Two of patients had moderate plagiocephaly whereas others had mild plagiocephaly. A total of 38 procedures (fat injections) were performed on these patients. Following procedures, 2 of patients were under corrected, 2 of who were over corrected, and others were adequate corrected. One of the patients developed fat necrosis. None of them showed persistent over correction. Authors believe that autologous fat transplantation is a safe and effective method, in patients with anterior plagiocephaly who have not been operated, to improve patients' appearance and, subsequently, their self-esteem as well as their social function.

Incidence of Familial Craniosynostosis Among Patients With Nonsyndromic Craniosynostosis.

BACKGROUND: Craniosynostosis has an incidence of 1 in 2000 to 2500 live births, and is categorized into syndromic and nonsyndromic types. Nonsyndromic ones can be familial in which more than one of the family members are involved. METHODS: This is a prospective study which is carried out from April 2015 to January 2018 in 2 academic hospitals. Those patients who had nonsyndromic craniosynostosis and completed medical follow-up were included in the study as well as their 1st degree relatives. Age of patients, gender, existing consanguineous marriage, type of deliveries, type of pregnancy (assisted reproductive technologies [ART] versus sexual intercourse), severity and type of craniosynostosis were gathered. RESULTS: Ninety-four (46.0%), 58 (28.4%), 28 (13.7%), 16 (7.8%), and 8 (3.9%) of patients had trigonocephaly, scaphocephaly, anterior plagiocephaly, complex, and brachycephaly, respectively. A total number of 204 patients were included in the study. Of all 204 families which were included, 30 (14.7%) families had positive familial history. Familial patients were determined in 10, 15, 8, 1, and 5 patients with scaphocephaly, trigonocephaly, anterior plagiocephaly, rachycephaly, and mixed type. Male to female ratio was 2:1, 1.9:1, 1.3:1, 1:1, and 1:1 for scaphocephaly, trigonocephaly, anterior plagiocephaly, brachycephaly, and mixed craniosynostosis. Twelve (5.9%) women had applied ART. CONCLUSION: Present study reveals that metopic suture is the most frequent craniosynostosis within nonsyndromic types. All the types of nonsyndromic craniosynostosis had male prevalence but for complex one which was equal in both gender. Nonsyndromic craniosynostosis in about 14.7% of patients was familial.

Various Colored Splints for Each Type of Rhinoplasty.

In rhinoplasty, one of the most popular aesthetic surgical procedures worldwide, several different techniques are utilized when performing a rhinoplasty procedure. Many complications can arise postoperatively depending on the surgical approach and technique utilized. A method to reduce immediate postoperative complications has been identified. The use of different colored nasal splints for various surgical procedures could assist in identifying high-risk patients to the postsurgical recovery team and the clinical staff. In this prospective 10-year study, patients were divided into 2 groups. In Group I, the green-colored splint was applied to all patients, whereas in Group II, patients were divided into 3 subgroups. Patients undergoing rhinoplasty and septoplasty, rhinoplasty, and minimally invasive rhinoplasty were placed in Subgroup I, Subgroup II, and Subgroup III, respectively. Different survey questionnaires were designed for patients, the surgical team, the postsurgical recovery team, the follow-up care team, and the clinical staff. A total of 2,680 (88%) patients were females, whereas 332 (12%) patients were males. There was no significant difference in surgeon's responses between 2 groups (p > .05). Between the 2 groups, there was a significant difference in the postsurgical recovery team and the follow-up care staff (p < .001). Patients in Group II were significantly more aware of their conditions and possible complications (p < .001). The current study reveals that patients undergoing rhinoplasty should be identified through colored splints, particularly patients whose surgery accompanies a high possibility of complications. In such patients, colored splint is a red flag for surgical and postsurgical nurses and staff who are providing health care to patients.

Prevalence of Rare Craniofacial Clefts.

BACKGROUND: Craniofacial clefts are extremely rare congenital malformations that have adverse functional, psychosocial, and aesthetic effects on patients' life. Although the exact incidence is unclear, it is estimated between 1.4 and 4.9 per 100,000 live births. Prevalence of the rare craniofacial clefts is imprecise due to the paucity of literature as well as their etiologies. METHODS: All the patients with rare craniofacial clefts during 10 years in a plastic surgery tertiary referral hospital were included, and Tessier craniofacial clefting classification was used for classifying the clefts. RESULTS: Of 964 patients with craniofacial clefts, 80 (8.29%) patients were identified with rare craniofacial clefts. There were 39 (48.7%) males and 41 (51.3%) females. Family history was determined positive in 30 (37.5%) patients. Tessier number 0 (58.7%) was the most common cleft in the authors' study. Tessier numbers 8, 13, and 30 were the rarest clefts. There was no patient with Clefts numbers 5, 6, or 9. Maternal smoking during pregnancy was observed in 1 (1.3%) of the women and 3 of the women had used drugs, 1 of them used the dexamethasone tablets and 2 of them could not remember name of the used drug. CONCLUSIONS: Tessier number 0 was the most common cleft and Tessier numbers 8, 13, and 30 were the rarest types. The precise etiology of rare craniofacial clefts remained undetermined in this study. Women should be educated about the risk factors and subsequent ways of preventing from these risk factors.

How Well Does Non-mass Enhancement Correlate With DCIS/Invasive Cancer?

INTRODUCTION: Contiguous non-mass enhancement (NME) often coexists with a solid tumor component on MRI, but it can be challenging to predict whether NME represents invasive breast cancer, ductal carcinoma in situ (DCIS), benign disease, or biopsy site reaction. The purpose of this study was to determine the association between the size/extent of NME and the presence of invasive cancer and/or DCIS on final pathology. METHODS: This was a single institution retrospective analysis of a prospectively maintained breast cancer registry (2010-2020). Female patients who underwent surgical resection were included if they had a diagnosis of invasive breast cancer (with or without DCIS) and had an MRI showing both a solid mass and contiguous NME. The size of NME on MRI was compared with the size of invasive cancer and/or DCIS on the final pathology. RESULTS: From a total of 3443 patients, 225 patients were included. 86.2% had invasive ductal carcinoma (IDC), and 12.0% had invasive lobular carcinoma 76.9% were ER+, 16.4% were HER2+, and 13.3% were triple negative breast cancer (TNBC). 18.7% received neoadjuvant chemotherapy (NCT) of whom 31% achieved a complete radiographic/pathologic response. Pearson correlation coefficients (r) between the size of NME and invasive cancer/DCIS showed a strong and positive correlation of MRI NME with DCIS on pathology in patients without NCT. Subgroup analysis showed the strongest correlations for NME and DCIS among non-white (r = .70) and HER2 + patients (r = .74) who did not receive NCT. CONCLUSIONS: Strong correlations between NME and DCIS were found for HER2 + disease and non-white patients, but only modest correlations were found for other patient/disease characteristics. These correlations may impact decisions in surgical approach.

Age-related Survival Outcomes for Pancreatic Cancer by Age.

Background/Aim: Pancreatic cancer has a very poor prognosis, though outcomes based on age are not well characterized. The aim of current study was to analyze the survival of patients with pancreatic cancer based on age. Patients and Methods: Using National Cancer Data Base (NCDB), we determined survival outcome based on age among patients with pancreatic cancer. Results: A total of 423,482 patients between 2004 and 2017 were included in the study. Patients aged between 18 and 40-years-old had the worst 3-year survival rate among stage 1 disease. Conversely, patients over 65-years-old had the worst 3-year survival rate and presented with more advanced disease (clinical stages 3 and 4). Conclusion: Older patients with more advanced disease had worse survival.

Assessing Long-Term Neurodevelopment among Children with Non-Syndromic Single Suture Craniosynostosis.

Background: Single suture craniosynostosis (SSC) is a disorder, affecting brain growth. Reviewing literature reveals controversialists of papers in this field. Methods: This prospective study was conducted from 2014 to 2016. All the individuals, aged 2 to 16 years, whose medical records files were complete, with SSC from 1999 to 2013 were included. All patients had undergone cranial vault remodeling at Mofid Hospital, Tehran, Iran. Wechsler questionnaires, WPPSI-III and WISC-IV, were completed for each child based on his/her age. Results: Seventy children were included, with the mean age of 6.7 (±2.9) years. Forty-six (65.7%) children were boys while 24 (34.3%) were girls. Mean FSIQ for all of children was 95.5 (±13.2). Mean verbal IQ, performance IQ, verbal comprehension, perceptual reasoning, processing speed, and working memory are 93.4 (±14.1), 96.1 (±13.3), 97.5 (±13.9), 102.2 (±12.5), 94.5 (±9.8), and 97.5 (±12.9), respectively. There was statistically significant difference between FSIQ of children with SSC and that of unaffected children (P-value<0.05). There was significant difference between verbal IQ of children with SSC and that of unaffected ones (P-value< 0.007). There was significant difference between in processing speed between affected children and unaffected children (P-value<0.012). Conclusion: Children, aged 2 to 6 years, with SSC had a significantly lower Verbal IQ, and children, aged 6 to 16 years, with SSC had a significantly lower processing speed than their healthy counterparts. Though FSIQ of children with SSC falls within normal range, it is a little lower than healthy peers.

Trends of the Extra-Hepatic Biliary Cancer and Its Surgical Management: A Cross-Sectional Study From the National Cancer Database.

Introduction Biliary cancers are rare cancers with poor prognoses. In this study, we aimed to evaluate trends in early detection and surgical treatment and approaches in extra-hepatic biliary tract cancers (EBCs) over 13 years in the US. Methods The most recent data on patients diagnosed with EBC between 2004 and 2016 were extracted from the National Cancer Database (NCDB). The patients' demographics (sex, age, race), primary tumor sites, tumor grades and stages, staging modalities, diagnostic confirmation, surgical treatment modalities and approaches, and 90-day mortality were analyzed to determine trends. Results Biopsy was the most common staging modality in 63.9% of total 60,291 patients. The bile duct was the primary tumor site (55.0%). Histologic examination was the most common confirmatory diagnostic modality (77.5%). The most common stage was stage II (23%). The most common surgical treatment modality was radical surgery (13.88%). The open surgical approach was used in 27.1% of patients, followed by a laparoscopic approach (4.3%). Conclusion EBC showed no significant change in the trends of the stage at diagnosis, treatment modality, and extent of surgical procedures despite advances in surgical diagnostic and therapeutic modalities; however, the total number of cases slightly increased between 2004 and 2016.

Circulating tumor DNA for breast cancer: Review of active clinical trials.

BACKGROUND: The new diagnostic concept of liquid biopsy is based on the analysis of circulating tumor cells (CTCs) and cell-free DNA (ctDNA). In addition to providing a more comprehensive view of the tumor characteristics including molecular variations, ctDNA analysis through liquid biopsies may also allow for a non-invasive, rapid, and cost-effective identification of biomarkers for tumor detection and monitoring of tumor progression. OBJECTIVE: In this review, we summarize key active clinical trial studies involving utilization of ctDNA derived from liquid biopsy in the early and metastatic breast cancer setting. With this, we also provide a brief overview of the potential future implementations of the LB technology and outlining how ctDNA analysis needs to be standardized through the performance of similar clinical studies. METHODS: A review was conducted on Clinicaltrials.gov to identify active trials related to use of circulating tumor DNA (ctDNA) for breast cancer. Search terms included "breast cancer," "liquid biopsy," and "ctDNA." CONCLUSION: While LB is gaining traction in many cancer settings, its use in BC is still early and warrants more investigation in breast cancer diagnostic and treatment settings, including early detection of disease recurrence.

Translation, validation and psychometric evaluation of the Persian (Farsi) version of the Low Anterior Resection Syndrome Score (LARS-P).

INTRODUCTION: Low anterior resection (LAR) for rectal cancer affects bowel function after the operation, causing a group of symptoms known as LAR Syndrome (LARS). LARS score is a patient-reported questionnaire to assess bowel dysfunction after the LAR operation. This study performed to validate the Persian (Farsi) translation of the LARS score and to investigate the psychometric properties of the score. The impact of LARS on the Quality of Life (QoL) of patients was also assessed. MATERIALS AND METHODS: The LARS score was translated into Persian. Participants with a history of rectal cancer and low anterior resection were asked to complete the LARS score questionnaire. They were also asked a single question evaluating the impact of bowel function on QoL. Discriminative validity, convergent validity, sensitivity, and specificity of the questionnaire were calculated. A group of patients completed the score twice to assess the reliability of the questionnaire. RESULTS: From 358 patients with rectal cancer, 101 participants completed the Persian questionnaire. Answers of a high fraction of participants showed a moderate/perfect fit between their LARS score and their QoL. The Persian score demonstrated good convergent validity. It was able to differentiate between participants in terms of gender and T staging of the primary tumor. The score had high reliability. CONCLUSION: The Persian translation of the LARS score has excellent psychometric properties compared to previous translations in other languages. Therefore, it is a valid and reliable questionnaire to assess LARS.

Prefabricated Skin Excision in Face Lift: A Simplified Technique.

BACKGROUND: The demand for facial plastic surgery has dramatically been increased in recent years. Over the last decade, numerous methods have been improved for facelift surgery. Despite these modifications, skin excision technique has not changed significantly. In this study, authors have tried to introduce a new technique regarding skin excision at the initial step of facelift surgery. METHODS: A prospective study from 2012 to 2017 on 52 patients was carried out to apply a new technique for facelift ''Prefabricated skin excision method'' for all eligible patients undergoing facelift surgery. The skin calling for excision was marked by the surgeon, and then, an analgesic drug was administered. Then, excision of the marked part of the skin was performed and afterward the dissection of the superficial musculoaponeurotic system (SMAS) was performed with the direct exposure. RESULTS: All patients were female, and 50 (96.1%) cases were primary face lift and 2 (3.9%) cases were secondary. There were no complications among the patients. CONCLUSION: Facilitating the manipulation of deep layer, using this technique led to the further exposure of the surgical site, and more preferable hemostasis was achieved as well.

Midgut volvulus is a rare cause of intestinal obstruction in adults: A case report.

INTRODUCTION: The incidence of midgut vovulus is rare in adults. However, a significant number of cases were seen in infant and children. PRESENTATION OF CASE: We report a case of a 34-year-old male who presented to the emergency room with persistent periumbilical abdominal pain without any other symptoms. Contrast-enhanced CT showed clearly the typical finding of midgut volvulus like whirlpool sign, corkscrew sign, and the superior mesenteric vein to the left of superior mesenteric artery. The patient was planned for Ladd's procedure and emergency laparotomy performed successfully with an uneventful postoperative recovery. DISCUSSION: Managing midgut volvulus is based on presentation. In symptomatic cases surgery is the treatment, but in asymptomatic cases, treatment is controversial. CONCLUSION: Although midgut volvulus is rare in adults, it should be considered as an intestinal obstruction.

Conservative versus Surgical Therapy in Managing Patients with Facial Nerve Palsy Due to the Temporal Bone Fracture.

Facial nerve paralysis is classified into immediate or delayed-onset palsy, and affected patients should be treated through conservative or surgical therapy. Appropriate treatment is somewhat debated as well as proper time for performing surgery. This study aimed to assess treatment outcome between conservatively and surgically treated groups and to determine the appropriate time of surgery in selected patients for surgery. Twenty-four patients from April 2008 to July 2015 were included. Performing decompression surgery within the first 2 months following the trauma accompanies a better prognosis ( p -value < 0.05). Eleven patients were managed conservatively, and 4 of them demonstrated immediate onset and 7 indicated delayed onset. Nine patients obtained normal nerve function, one patient had partial palsy, and one of them had complete palsy. There was no significant difference in the rate of recovery between types of the treatment ( p -value > 0.05). Decompression surgery is recommended in the first 2 months after the trauma for immediate onset and also complete degeneration on electroneuronography.

Sumatriptan Increases Skin Flap Survival through Activation of 5-Hydroxytryptamine 1b/1d Receptors in Rats: The Mediating Role of the Nitric Oxide Pathway.

BACKGROUND: Random pattern skin flaps are applicable for reconstructing any defect in plastic surgery. However, they are difficult to apply because of necrosis. Sumatriptan, a selective 5-hydroxytryptamine 1b/1d agonist, is routinely used to offset acute migraine attacks. Recent studies have suggested that sumatriptan may induce vasodilation at lower concentrations. The authors' aim is to investigate the effect of sumatriptan on skin flap survival and the role of nitric oxide in this phenomenon. METHODS: Seventy-two male Sprague-Dawley rats were divided into eight groups. Increasing doses of sumatriptan (0.1, 0.3, and 1 mg/kg) were given intraperitoneally to three different groups after dorsal random pattern skin flaps were performed. To assess the exact role of 5-hydroxytryptamine 1b/1d receptors, GR-127935 was administered solely and with sumatriptan. N-ω-nitro-L-arginine methyl ester (L-NAME, a nonselective nitric oxide synthase inhibitor) was used to evaluate any possible involvement of nitric oxide in this study. All rats were examined 7 days later. RESULTS: The authors' results demonstrated that flap survival was increased by lower doses of sumatriptan compared to a control group for both 0.3 mg/kg (p = 0.03, mean difference = 32, SE = 8) and 0.1 mg/kg (p = 0.02, mean difference = 26, SE = 8). This protective effect was eliminated by coadministration of GR-127935 or N-ω-nitro-L-arginine methyl ester with sumatriptan. Histopathologic studies revealed a significant increase in capillary count and collagen deposition and a decreased amount of edema, inflammation, and degeneration. CONCLUSIONS: Sumatriptan in lower concentration increases skin flap survival by means of activation of 5-hydroxytryptamine 1b/1d receptors. This effect is mediated through the nitric oxide synthase pathway.

The trend of burn mortality in Iran - A study of fire, heat and hot substance-related fatal injuries from 1990 to 2015.

INTRODUCTION: Burn injuries are a major cause of preventable mortality worldwide. To implement preventive strategies, a detailed understanding of the rate and trend of fatal burn injuries is needed. The aim of this study was to determine the rate and trend of burn mortality at national and province level in Iran from 1990 to 2015. MATERIALS AND METHODS: The data were retrieved from various sources: the Death Registration System, cemetery databases, the Demographic and Health Survey and three national population and housing censuses. ICD-10 codes were converted to Global Burden of Disease (GBD) codes for comparability. After addressing the incompleteness of death data, statistical methods such as spatio-temporal modelling and Gaussian Process Regression (GPR) were applied to estimate the levels and trend of death and cause specific mortality. RESULTS: The number of deaths due to burning across Iran was 80,625, with a male to female ratio of 0.88, 0.94 and 1.14 in 1990, 1995 and 2015, respectively. The annual percentage change of age-standardized death rate from 1990 to 2015 was -5.42% and -4.22% in women and men, respectively. The burn-related age-standardized mortality rate decreased considerably from 5.97 in 1990 to 1.74 per 100,000 in 2015. The mortality rate due to burns was highest among those aged more than 85 years, especially in Ilam province. CONCLUSION: This study showed a decline in burn mortality in Iran from 1990 to 2015. Continued efforts to reduce the burden of burns are needed to accelerate this progress and prevent injuries.

Laparoscopic Omentopexy, Rectus Sheath Tunneling and Implantation of the Peritoneal Dialysis Catheter Using a Peritoneal Dialysis Port.

BACKGROUND: Prophylactic laparoscopic omentopexy is a safe technique to prevent peritoneal dialysis (PD) catheter obstruction. For the first time, we would like to describe a surgical technique in which the omentopexy is done using a single PD port which is used for the omentopexy, PD catheter insertion, and the rectus sheath tunneling of the catheter. METHODS: The surgical method of the omentopexy using the PD port (US Patent 20170119430) will be thoroughly described. To evaluate the surgical method, we performed the procedure in 15 consecutive patients with chronic renal failure and followed up the patients. RESULTS: No intraoperative complication was observed. During the follow-up period, catheter flow failure due to omental wrapping was found in none of the patients. No other complication including exit-site infection, peritonitis, or catheter leakage was detected. CONCLUSION: Using this technique the catheter can not only be implanted through a proper and long rectus sheath, but the omentopexy can also be done without an additional port. This can reduce port-site complications and dialysis fluid leakage.

Outcomes of Biliointestinal Bypass among Iranian Obese Patients.

Background There are several surgical approaches to treat obesity not cured with medical approaches. Each method has its advantages and complications. In here, we have conducted a study to evaluate complications of biliointestinal bypass surgery (BIBP). Methods A prospective study was conducted in a private hospital from 2002 to 2016. Those patients, not previously operated for morbid obesity, were eligible. Mean follow-up period was 89 months ( ± 54 months; range: 73-108 months). Main outcome measures were weight, BMI (body mass index), concentrations of blood lipids and glucose, liver transaminases, and obesity-related comorbidities and complications. Results Twenty-three consecutive patients with morbid obesity, including 16 women (69.7%) and seven men (31.3%) with mean age 38.47 ± 10 years (range: 26-57 years) underwent surgery. At the end of follow-up period, a mean BMI reduction of 12.2 kg/m 2 kg/m 2 ( p < 0.001)] was observed. An excess weight loss (EWL) of 63% ( ± 34) was achieved at the end of the study. Additionally, total cholesterol and triglyceride levels decreased postoperative significantly. The main long-term complications were flatulence (60%), borborygmus (47.8%), mal odorous stool (30.4%), and diarrhea (21.7%). Revision rate was 4.34%. There were no cases with irreversible hepatic injury, deaths due to the surgery, or progressive renal failure. Conclusion BIBP seems to be a safe, easily reversible, and one of valid therapeutic approaches in morbidly obese patients. BIBP has the potential to achieve durable weight loss and offers an improved quality of life.
