A huge benign gastric schwannomas presented with upper and lower gastrointestinal bleeding: a case report and literature review.

Gastric schwannomas (GS) are rare mesenchymal tumors from Schwann cells in the gastrointestinal (GI) tract, representing 2-6% of such tumors. We report a 52-year-old woman who experienced abdominal pain, hematemesis, and melena, initially suspected of having a GI stromal tumor through ultrasound and computed tomography abdomen. Despite no active bleeding found during an upper endoscopy, she underwent a successful open subtotal gastrectomy, with histopathology confirming GS. The diagnosis of GS, which may mimic other GI conditions, relies heavily on imaging and histopathological analysis due to its nonspecific symptomatology, including the potential for both upper and lower GI bleeding. This case underscores the diagnostic challenges of GS and highlights surgical resection as the preferred treatment, generally leading to a favorable prognosis.

Design of Experimental Approach for Development of Rapid High Performance Liquid Chromatographic Process for Simultaneous Estimation of Metoprolol, Telmisartan, and Amlodipine from Formulation: Greenness and Whiteness Evaluation.

The design of an experimental approach, the Box-Behnken design, was implemented to optimize the chromatographic condition to develop a rapid HPLC procedure for quantification of a ternary mixture of metoprolol (MET), telmisartan (TEL), and amlodipine (AML) from the formulation. The perturbation plots, contour, and 3D response surface pictures were developed to study the impact of each variable on the analytes' retention time and the probable interaction between the parameters with fewer chromatographic runs. The optimized HPLC method separated the three analytes within 5 min with excellent selectivity and peak shape on a Zorbax C18 HPLC column using acetonitrile and phosphate buffer (20 mM, pH 5.8) with isocratic elution at a 1.1 mL/min flowrate. A wavelength 230 nm was utilized to monitor the elute. The validation of proposed method demonstrated a wide linearity range of 10-200 µg/mL for MET and TEL and 5-50 µg/mL for AML along with an excellent correlation coefficient. The correctness of the HPLC approach was further confirmed by excellent recovery of the added amount of analytes utilizing the standard addition technique. The recommended HPLC approach was employed safely for quality assurance of the formulation, because the evaluation of the method's greenness and whiteness confirmed the environmentally friendly nature of the approach.

An Extremely Rare and Aggressive Case of Undifferentiated Carcinoma With Osteoclast-Like Giant Cells of the Pancreas Presenting as a Paraneoplastic Syndrome: A Case Report and Literature Review.

Undifferentiated carcinoma with osteoclast-like giant cells (UC-OGC) is a rare tumor type of pancreatic cancer. Paraneoplastic syndromes, an idiopathic inflammatory myositis characterized by various skin manifestations (such as dermatomyositis (DM)), cannot be attributed to the primary tumor itself. Here, we report an unusual case of UC-OGC presenting as a paraneoplastic syndrome, the first reported from Saudi Arabia and the Arabian Gulf states. A 49-year-old Eritrean woman with known DM was referred to our hospital with a left-sided pleural effusion. Computed tomography of the abdomen revealed a large necrotic splenic mass (~17 × 12.9 × 18.2 cm). The patient underwent exploratory laparotomy with en bloc resection of the mass (splenectomy, distal pancreatectomy, and partial excision of the left hemidiaphragm). Following a histopathological examination of the mass, UG-OGC of the pancreas, presenting as a paraneoplastic syndrome, was diagnosed. To our knowledge, this case is the first to present a paraneoplastic syndrome associated with UC-OGC. The identification of an exceedingly rare tumor presenting atypically as a paraneoplastic syndrome shows the importance of conducting comprehensive examinations of patients with malignancies, emphasizing the need for more reports of similar cases.

An Overview of Developmental Dysplasia of the Hip and Its Management Timing and Approaches.

Developmental dysplasia of the hip (DDH), if uncorrected, can result in several chronic abnormalities, including chronic hip pain, degenerative arthritis, and gait abnormalities. The outcome of DDH generally depends on the age of presentation; a worse prognosis is linked to a higher age of presentation. Although treatment continues to be a challenge, recent advancements in the field have improved our understanding of the disease, which has resulted in advancements in DDH surveillance during infancy and the reduction of complications with early intervention. The databases used for this overview include Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Library, MEDLINE, and EMBASE. These databases were used to search for ongoing trials related to the management and diagnosis of DDH.

Clinicohistological Characteristics of Patients with Oral Lichenoid Mucositis: A Retrospective Study for Dental Hospital Records.

Oral lichenoid mucositis (OLM) of the oral mucosa is a histological diagnosis mainly characterised by a band of inflammatory infiltrate in lamina propria and basal cell degeneration. These features describe oral lichen planus or oral lichenoid reaction. However, it could be seen in oral dysplasia. The study aimed to assess the demographics and clinicohistological characteristics of patients with OLM and their relevance to dysplastic changes in the oral mucosa. This was a cross-sectional and retrospective study of archived and electronic records of individuals with histological confirmation of OLM at King Saud University Medical City, Saudi Arabia. The descriptive and correlation assessments were used to describe the demographics and clinicohistological characteristics and their associations, respectively [p < 0.05]. The analysis included 140 records of patients with histological confirmation of OLM with a mean age of 47 (±13), and 57% (n = 81) were females. Notably, 40% of patients had at least one medical condition, mainly diabetes mellitus, 74% were asymptomatic, and 52% had lesions in the buccal mucosa. Dysplasia was seen in 18 (12%) of the 140 reviewed records. Regarding the associations between study variables, dysplastic changes were associated with the male gender [p = 0.024] and were of no significance with increased age [p = 0.594]. Moreover, having oral symptoms was associated with older age [p < 0.001], medical history of diabetes [p = 0.0132] and hypertension [p < 0.001]. The present study findings could help indicate the individuals with histologically confirmed OLM who suffer the most from the clinical disease and have an increased risk of dysplastic changes. Therefore, symptomatic management and long-term follow-up can be planned accordingly.

Intraoral angiosarcoma with unusual clinical presentation: A case report.

Introduction: Angiosarcoma is a rare and highly aggressive soft tissue malignancy originating from vascular and lymphatic endothelial cells. Epithelioid angiosarcoma is the rarest subtype of angiosarcoma, characterized by the proliferation of large polygonal cells with an epithelioid feature. The occurrence of these tumors in the oral cavity is highly uncommon, and immunohistochemistry staining is essential to differentiate epithelioid angiosarcoma from mimicking lesions. Aim: To present a case of intraoral angiosarcoma with an unusual clinical presentation and behavior and to report, to the best of our knowledge, a first primary appendix epithelioid angiosarcoma with metastasis foci in the oral cavity. Objectives: To discuss the clinical, histological, and immunochemical features of an unusual case of intraoral angiosarcoma. Case report: A 53-year-old Saudi female with an uncommon clinical presentation of intraoral angiosarcoma. The patient reported the lesion being painless, slowly growing, and of a six-month duration. The microscopic examination and immunohistochemical evaluation showed epithelioid angiosarcoma. The tumor cells were positive to ERG, FLI 1, and CD31 (focal) and negative to CK HMW, CD45, S100, HMB 45, D2-4, and CD 34. Discussion: Due to the extremely rare occurrence and non-characteristic presentation of angiosarcoma in the oral cavity, many lesions maybe included in the differential diagnosis. Thus, making the diagnosis of intraoral angiosarcoma difficult.

Unusual Acute, Massive Lower Gastrointestinal Bleeding Secondary to a Proximal Jejunal Gastrointestinal Stromal Tumor: A Case Report.

The most common primary non-epithelial neoplasms of the gastrointestinal (GI) tract are gastrointestinal stromal tumors (GISTs). Ten percent (10%) of GISTs arise from the jejunum. Usually, patients complain of abdominal discomfort, but they may present with complications such as intestinal obstruction or bleeding. This report describes a 35-year-old male who presented with unusually massive, acute lower GI bleeding. After resuscitation and investigations (including a contrast-enhanced computed tomography of the abdomen and lower GI endoscopy), the patient underwent diagnostic laparoscopy and bowel resection of the affected section with anastomosis, and he had an eventful postoperative course. Studies suggest that GI bleeding in GIST occurs due to the ulceration and necrosis of the overlying mucosa caused by the pressure effect of the mass. Small-bowel GISTs are categorized based on their size. Many guidelines have advocated conservative management for small GISTs (<2 cm) that are in the jejunum. This patient has a rare case of a small jejunal GIST with a rare presentation of massive lower GI bleeding. A multidisciplinary approach is useful in managing such cases, and our case showed that laparoscopic intervention is a feasible option in a stable patient with massive lower GI bleeding.

Is Appendiceal Diverticulitis Mimicking Acute Appendicitis?

Appendicular diverticulitis (AD) is a rare entity characterized by the inflammation of the arising diverticulum of the appendix. It has been reported to carry a high risk of perioperative complications, such as bleeding and perforation. Furthermore, multiple articles have highlighted the importance of diagnosing AD early due to its strong association with malignancies. Limited published cases concerning AD in our country and globally are available in the literature. Hence, we present in this article a case series of five exciting cases of incidental findings of AD that were initially diagnosed as acute appendicitis based on clinical evaluation and imaging findings. In our series, we performed a retrograde evaluation of the computed tomography scans of all five cases that showed diverticula. In conclusion, histopathological evaluation remains the method of choice to reach the definitive diagnosis; however, it is essential to highlight the relevance of imaging in diagnosing AD preoperatively in the early stages to reduce morbidity and mortality.

A Rare Case and Presentation of Traumatic Penetrating Aortic Arch Injury: A Case Report and Literature Review.

A penetrating injury to the thoracic aorta is an extremely rare, life-threatening condition, with a high overall mortality rate. The incidence of a penetrating injury to the aortic arch is unknown because the majority of patients die before receiving adequate treatment due to excessive bleeding. Through a literature review, 23 cases of favorable outcomes were found. We report the first case from the Arab Gulf states. We present the extremely rare case of a 23-year-old male who presented to the emergency department with stable hemodynamics after being stabbed in the left supraclavicular region. The investigation revealed that he suffered from aortic arch transection and contrast extravasation. The patient was rushed to the operating room, where a primary repair was performed through a median sternotomy approach. The patient was discharged on the 14th postoperative day without complications. Penetrating chest trauma (aortic arch injury) is uncommon, and it is typically fatal at the scene or time of injury, even in patients who arrive at the emergency department alive or while undergoing surgery. CT aortography should be performed on patients with normal vital signs but abnormal clinical findings suggestive of a vascular injury. For injuries of types II to IV without concomitant injuries, immediate surgical repair is recommended. Aortic arch penetrating injuries continue to be extremely lethal. Emergency surgical repair remains the standard of care and is associated with high morbidity and mortality rates. However, managing such uncommon injuries remains a formidable challenge. We encourage additional studies.

Enabling Intelligent IoTs for Histopathology Image Analysis Using Convolutional Neural Networks.

Medical imaging is an essential data source that has been leveraged worldwide in healthcare systems. In pathology, histopathology images are used for cancer diagnosis, whereas these images are very complex and their analyses by pathologists require large amounts of time and effort. On the other hand, although convolutional neural networks (CNNs) have produced near-human results in image processing tasks, their processing time is becoming longer and they need higher computational power. In this paper, we implement a quantized ResNet model on two histopathology image datasets to optimize the inference power consumption. We analyze classification accuracy, energy estimation, and hardware utilization metrics to evaluate our method. First, the original RGB-colored images are utilized for the training phase, and then compression methods such as channel reduction and sparsity are applied. Our results show an accuracy increase of 6% from RGB on 32-bit (baseline) to the optimized representation of sparsity on RGB with a lower bit-width, i.e., <8:8>. For energy estimation on the used CNN model, we found that the energy used in RGB color mode with 32-bit is considerably higher than the other lower bit-width and compressed color modes. Moreover, we show that lower bit-width implementations yield higher resource utilization and a lower memory bottleneck ratio. This work is suitable for inference on energy-limited devices, which are increasingly being used in the Internet of Things (IoT) systems that facilitate healthcare systems.

A Constitutional Mismatch Repair Deficiency Syndrome Presented With an Advanced Rectal Cancer in a Juvenile Female: A Case Report and Literature Review.

The constitutional mismatch repair deficiency (CMMRD) syndrome is a rare and challenging condition with a poor prognosis. It results from biallelic mismatch repair gene mutations and leads to multiorgan cancers. Therefore, we report the first case of advanced juvenile rectal cancer related to CMMRD syndrome in the Gulf region. She is a 13-year-old female, born to non-consanguineous parents with a positive family history of malignancy, presented with an eight-month history of a retractable bulging anal mass associated with diarrhea mixed with blood and constitutional symptoms. She was cachectic with café au lait spots all over her body. Upon investigation, she was found to have invasive rectal adenocarcinoma. The case was started on neoadjuvant chemoradiotherapy in addition to genetic testing which showed a homozygous pathogenic variant in PMS2, indicating CMMRD syndrome. The patient underwent pre-operative post-neoadjuvant reassessment followed by laparoscopic total proctocolectomy with ileal J-pouch creation and ileoanal anastomosis with temporary diverting loop ileostomy which later on was reversed with no complications or recurrence. The family declined to continue the adjuvant therapy but accepted the surveillance programs and genetic testing. Unusual or late presentation secondary to a very rare syndrome like CMMRD is a major challenge to clinicians, hence a high index of suspicion and proper utilization of genetics programs might be the best available solutions.

A Rare Case of Pancreatic Adenocarcinoma With Incidental Synchronous Hepatic and Sigmoid Colonic Metastasis: A Case Report and Literature Review.

Metastasis of pancreatic adenocarcinoma to the colon is a very rare condition that might be underdiagnosed and underreported in the literature. We report a very rare case of incidental findings of sigmoid metastasis secondary to pancreatic adenocarcinoma in a 60-year-old Saudi male, who is a non-smoker with a normal medical and surgical history. The patient presented to a primary care clinic with abdominal bloating and vague on/off abdominal pain for almost 1 year as well as unintentional weight loss without lower gastrointestinal (GI) symptoms. After the case was discussed in the multidisciplinary tumor board, the patient was started on systematic palliative chemotherapy. However, after receiving the first cycle, he started to deteriorate rapidly and succumbed to secondary cardiopulmonary arrest. Cases of synchronous metastasis of pancreatic adenocarcinoma to the colon might not be well known or common. However, a high index of suspicion and individualizing the workup tools may need to be used.

Large Asymptomatic Retroperitoneal Ganglioneuroma Displacing Major Abdominal Organs and Vessels in an Adult.

BACKGROUND Ganglioneuromas (GNs) are benign neuroblastic tumors. These extra-cranial solid tumors are common in childhood but unusual in adults. Patients with GNs typically do not have any symptoms and the tumors usually are incidental findings. However, if a GN is large enough to compress adjacent organs, complications can occur. Furthermore, even in patients who have incomplete resection of a GN, long-term survival rates are high. After a GN is seen on imaging, the diagnosis usually is made with a biopsy and treatment is with surgery alone. CASE REPORT A 29-year-old woman was referred to General Surgery from the Gynecology Clinic for an incidental finding of an abdominal mass on routine ultrasound for secondary infertility and admitted for an investigation. Abdominal and pelvic computed tomography (CT) and magnetic resonance imaging showed a retroperitoneal mass that measured 6.318×22 cm arising from the paravertebral region with intraspinal extension. The mass was displacing the patient's thoracic aorta, abdominal inferior vena cava, and ureters. A CT-guided biopsy revealed a GN. Debulking surgery was performed and a small amount of residual tumor was left in the paravertebral nerve roots. The patient recovered well with no complications. The diagnosis of GN was confirmed with pathology, which was reviewed by the Tumor Board; the Board agreed that only follow-up in the Surgery Clinic was needed. During the patient's last visit, 10 months after surgery, a follow-up CT scan showed that the residual tumor was stable. CONCLUSIONS GNs are benign abdominal and retroperitoneal tumors that are typically asymptomatic and detected incidentally. Surgical resection is the treatment of choice and even when it is incomplete, the prognosis for patients is excellent.

Trends in bariatric surgery and incidentalomas at a single institution in Saudi Arabia: a retrospective study and literature review.

BACKGROUND: Data are lacking on trends in bariatric surgery and the frequency of incidental findings in Saudi Arabia. OBJECTIVE: Report on trends in bariatric surgery as well as our experience in incidental findings along with a literature review (mainly on gastrointestinal stromal tumor). DESIGN: Retrospective chart and literature review. SETTINGS: Academic tertiary care center. PATIENTS AND METHODS: We conducted a retrospective study at King Khalid University Hospital and analyzed the data collected from 2009 to 2019. We collected data on age, body mass index (BMI), H pylori infection, type of bariatric surgery performed, and type and location of incidental findings. MAIN OUTCOME MEASURES: Incidental findings during or after bariatric surgery (in pathology specimen). SAMPLE SIZE: 3052 bariatric surgeries, 46 patients with incidentalomas. RESULTS: The mean and standard deviation for the age of the 46 patients with incidentalomas was 42.1 (13.9) years and the mean (SD) preoperative BMI was 43.4 (6.4) kg/m2. Of 3052 bariatric surgeries performed, the most common type was sleeve gastrectomy (93.9%), followed by gastric bypass surgery (4.58%) and gastric banding (1.47%). The total frequency of incidentalomas was 1.5%; 10.8% of patients had gastrointestinal stromal tumors (GIST), with the stomach being the commonest site for incidental findings. Eighty percent of the patients with GIST were positive for H pylori (P=.01 vs negative patients). CONCLUSION: The number of incidentalomas and other findings were consistent with other reports. All these findings suggest that bariatric surgeons should take special care before, during, and after a laparoscopic operation in obese patients. LIMITATIONS: Since this is a single-center, retrospective study, we did not collect data on important variables such as gender, socioeconomic status of the patient, and family history of obesity, and we did not perform a preoperative esophagogastroduodenoscopy. CONFLICT OF INTEREST: None.

Impact of COVID-19 pandemic on patient satisfaction and surgical outcomes: A retrospective and cross sectional study.

OBJECTIVE: The objective of this study was to evaluate the impact of the COVID-19 pandemic on patient satisfaction and surgical outcomes at King Khalid University Hospital in Saudi Arabia. BACKGROUND: The COVID-19 pandemic has greatly affected health care systems across developing and developed countries. Therefore, it is important to understand its impact on various parameters of patient care as regards revised infrastructure and policies in hospitals during the pandemic. METHOD: It is a retrospective cross-sectional study was conducted from 13-3-2020 to 26-4-2020 at King Khalid University Hospital in Saudi Arabia. Patient satisfaction and surgical outcomes were the main outcome measures. RESULTS: 331 participants were included in the study (median age: 53 years; 70% female), and 223 completed the patient's satisfaction survey. 260 of the surgeries were non-oncolog cases (78.6%) compared to 71 oncology cases (21.4%). With respect to the surgical outcomes, 12% of the patients required admission to the ICU, and 10.9% developed postoperative complications, most of which were infectious complications. Only 1.8% (6 patients) were re-admitted to the hospital. Three patients died within 30 days post-op (0.9%), all had emergency surgery. Regarding patient satisfaction, 77.6% and 93% of the patients reported that nurses and doctors, respectively, treated them with courtesy and respect, listened to them carefully, and provided clear explanations to them. 90.3% were satisfied with the hospital sanitary measures. 64.1% stated that they got written instructions at the time of discharge. CONCLUSION: The satisfaction level of patients was high for all the studied domains, and there were a small number of complications with overall good surgical outcomes. That indicates that all the actions and policies that were implemented during the pandemic were proven beneficial for the patients. It is recommended to continue those measures until the COVID-19 pandemic is over.

Laparoscopic resection of retroperitoneal intra-psoas muscle schwannoma: A case report and extensive literature review.

INTRODUCTION: Soft tissue tumors of Schwann cells in either the peripheral or cranial nerves are known as schwannomas or also as neurilemmomas. Limited data exists regarding psoas muscle schwannoma in the literature. Therefore, we have done an extensive literature review and found a total number of 46 cases of intra-psoas schwannoma including our case, which are summarized in this article along with reporting our new case. PRESENTATION OF CASE: We report a very rare case of primary left intra-psoas muscle schwannoma in a 39-year-old Saudi gentleman, smoker with an unremarkable medical and surgical history. The patient presented to the emergency department with exacerbated chronic lower abdominal pain since almost 2 years. After conforming the diagnosis, the patient was admitted electively and underwent uneventful laparoscopic hand-assisted resection. DISCUSSION: Schwannomas are neurogenic tumors which known to be solitary, benign, well circumscribed, encapsulated, and slow-growing tumors. Multiple imaging modalities are used to detect such a tumor. Although there is no consensus on the best surgical approach, endoscopic mini-laparotomy, laparoscopy (anterior [as in our case] or lateral), and robotic resection were reported with good outcomes. CONCLUSION: Retroperitoneal schwannoma and intra-psoas muscle variant are a rare entity, with slow growing rate and risk of malignant transformation. Therefore, high index of suspicion, good follow-up, and large-cohort studies are encouraged.

Two Histologically Different Primary Malignancies: Synchronous Obstructive Descending Colon Adenocarcinoma and Appendicular Carcinoid Tumor.

BACKGROUND Synchronous primary tumors are defined as 2 or more different histological tumors discovered in one patient at the same time or within a period of 6 months. Colorectal cancer is one of the most common cancers in the United States. Inversely, synchronous colorectal cancer and carcinoid tumors are rare. Carcinoid tumors can be classified into functioning and non-functioning tumors. Carcinoid tumors are steadily increasing in incidence. There is only 1 case reported in the literature as synchronous colorectal cancer and appendicular carcinoid. The difficulty is to manage 2 different types of malignancies at the same time. An optimal medical or chemotherapy strategy is needed. CASE REPORT A 29-year-old woman presented to the emergency room carrying with her computerized tomography (CT) abdomen and pelvic images showing bowel obstruction. Investigations confirmed an obstructing descending colon mass. She underwent colonoscopic stenting as emergency treatment with multiple biopsies. The pathology report came back positive for adenocarcinoma, and we planned to proceed with surgery. Intraoperatively, she was found to have an appendicular mass. The surgical team decided to proceed with laparoscopic-assisted subtotal colectomy. The postoperative course was uneventful, with no complications. The patient was discharged on postoperative day 6 in stable condition. CONCLUSIONS Synchronous colorectal cancer and carcinoid tumors are rare malignancies. The challenge is to find an optimal medical or chemotherapy strategy to manage both malignancies.

A cutaneous metastasis of unresectable rectal adenocarcinoma: A case report and literature review.

BACKGROUND: Colorectal cancer is ranked third among the most commonly diagnosed malignancies and fourth among the leading causes of cancer death in the world. However, only a few case reports are found in the literature regarding skin metastasis originating from rectal cancer, which usually shows widespread disease and poor prognosis. Approximately, 0.8% of the patients will have skin lesion as the first indication of a silent internal malignancy, which is rare. CASE REPORT: We report a complicated case of a 45-year-old male patient who referred to our highly specialized governmental hospital for diversion loop colostomy as well as biopsies of rectal and inguinal skin areas followed by palliative radiation therapy to the pelvis. Histopathological exam of rectal biopsies revealed moderately differentiated rectal adenocarcinoma, while the skin of the right inguinal area showed metastatic cutaneous rectal adenocarcinoma. Unfortunately, palliative radiation therapy was not started as the patient passed away secondary to respiratory failure which ended by cardiopulmonary arrest. CONCLUSION: A patient who is having new or evolving skin lesions with an oncology history should be well investigated as cutaneous metastasis is a strong possibility.

Characteristics of morbid obese patients with high-risk cardiac disease undergoing laparoscopic sleeve gastrectomy surgery.

INTRODUCTION: Bariatric surgery is an efficient and safe method of weight reduction among patients who have morbid obesity which cannot be treated by the conservative approach. Safety and feasibility of bariatric surgery among high-risk patients are understudied. Therefore, we aimed to report the patient-level characteristics and outcome among high-risk obese patients undergoing laparoscopic sleeve gastrectomy surgery in Saudi Arabia. METHODS: A retrospective analysis was performed among 13 morbidly obese (BMI >39 kg/m2) patients with high-risk cardiac disease, who were referred to Upper Gastro-Intestinal Surgery Clinic at King Khalid University Hospital, which is a center of excellence in bariatric surgery, for consideration for weight loss surgery. Retrospective data on preoperative weight, height, and BMI, operative details, perioperative complications, length of stay, and information on comorbidities and endocrinal disease were collected for analysis and reporting. RESULTS: A total of 13 patients were included in the analysis. Of the total, 61.5% were males with a mean age 40.38 (SD: 16.28) and a mean BMI 51.87 (SD: 7.69). The mean duration of surgery was 33.30 min (SD: 31.01), while the mean duration of anesthesia was 83.61 min (SD: 34.73). The mean length of stay was 6.76 days (SD: 3.89). Three patients required postoperative HDU admission with a mean length of stay of 1 day, while 5 patients required postoperative ICU admission with a length of stay ranging from 1 to 3 days. Within 30 days after discharge, only 1 patient required ER visit and none of the patients reported any postoperative morbidity and mortality. CONCLUSION: Through this study, we can conclude that laparoscopic sleeve gastrectomy surgery can be considered a safe procedure. However, further studies with a large sample size and a more robust methodology are needed to build upon the findings of this study.

Calcium Channel Blockers in Conjunction with Standard Iron-Chelating Agents for ß-Thalassemia Major: Systematic Literature Search.

Thalassemia is a genetic mutation of the α- or ß-globin chains that lead to defective erythropoiesis. This study aimed to collect evidences from all published studies that investigated the clinical effectiveness of calcium channel blockers (CCBs) in conjunction with chelation therapy for reducing iron overload in patients with thalassemia. A systematic search was conducted in PubMed, Institute for Scientific Information (ISI) Web of Science, Scopus, Cochrane Central Register of Controlled Trials, and Virtual Health Library. Original studies reporting the use of CCBs in patients with thalassemia were included for meta-analysis. A total of five randomized studies including 210 patients were included with a follow-up period of 3-12 months. There was no significant difference between amlodipine and control groups in increasing the heart T2* magnetic resonance imaging (MRI) [mean difference (MD) 95% confidence interval (95% CI) = -1.9 (-4.4 to 0.5), p = 0.119] or reducing the liver iron concentration [MD 95% CI = -0.046 (-0.325 to 0.2), p = 0.746]. Although there were no serious adverse events reported in the included trials, further studies are recommended to strengthen our findings.
