    Is Revisional Gastric Bypass as Effective as Primary Gastric Bypass for Weight Loss and Improvement of Comorbidities?2020Inngår i: Obesity Surgery, ISSN 0960-8923, E-ISSN 1708-0428, Vol. 30, s. 1219-1229Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Revisional gastric bypass (R-RYGB) surgery is utilized for the management of inadequate weight loss or weight regain observed after some cases of bariatric surgeries. Data on the mid-term effectiveness of primary gastric bypass (P-RYGB) compared to R-RYGB (e.g., post sleeve gastrectomy or gastric banding) are controversial. Methods: Retrospective chart review of all patients who received P-RYGB and R-RYGB (January 2011 - June 2015) at our center. One hundred and twenty patients who underwent P-RYGB and 34 R-RYGB who completed 18 months follow-up were included. We compared the effectiveness of P-RYGB with R-RYGB by assessing four anthropometric, two glycemic, and four lipid parameters, as well as the control of type 2 diabetes (T2DM), hypertension and dyslipidemia in terms of remission, improvement, persistence, relapse and de novo. The current study also assessed mortality and complications rates. Results: There were no significant differences in the baseline characteristics of patients who received P-RYGB with those who received R-RYGB in terms of age, gender and preoperative BMI. However, at 18 months: a) Patients who received P-RYGB had lower mean weight (P = 0.001) and BMI (P <0.001), reflected by a higher mean delta BMI (P = 0.02), TWL%(P <0.0001) and EWL%(P < 0.0001); b) No differences were observed between the two patients groups in terms of glycemic parameters, lipid profiles, and control of T2DM, hypertension, and dyslipidemia; and, c) No deaths were reported among both patients groups, and complication rates were comparable. Conclusion: Although R-RYGB effectively addressed inadequate weight loss, weight regain and recurrence of comorbidities after restrictive bariatric surgery, R-RYGB resulted in inferior weight loss compared to P-RYGB. There were no significant differences between the two procedures in terms of their clinical control of T2DM, hypertension and dyslipidemia. Both procedures exhibited comparable complication rates.

    Lorcaserin vs. Phentermine among non-surgical and surgical obese patients: Anthropometric, glycemic, lipid, safety and cost outcomes2019Inngår i: Annals of Medicine and Surgery, ISSN 2049-0801, Vol. 45, s. 75-81Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: To evaluate effectiveness, safety, and costs of Lorcaserin vs. phentermine among obese non–surgical and surgical patients (post bariatric surgery). Methods: This retrospective study retrieved charts of all patients (January 2013–June 2016) who received Lorcaserin or phentermine for 3 months. The study assessed anthropometric, glycemic, and lipid changes, as well as side effects and cost of medications among overweight and obese non-surgical (n = 83) and surgical patients (n = 46). These two patient groups were compared using Chi-square (χ2) and unpaired‘t’ test for qualitative and quantitative variables respectively. Results: At 3 months, among the non-surgical group, Phentermine patients had greater percentage of total weight loss (TWL%) (7.65 ± 8.26 vs. 2.99 ± 3.72%, P = 0.003), and greater BMI reduction (−3.16 ± 3.63 vs. −1.15 ± 1.53 kg/m2, P = 0.003) than Lorcaserin. Within the surgical group, Lorcaserin patients had significantly smaller TWL% (1.86 ± 5.06 vs. 7.62 ± 9.80%, P = 0.012), and smaller BMI reduction (−0.74 ± 1.80 vs. −3.06 ± 4.08 kg/m2, P = 0.012) than Phentermine. Lorcaserin exhibited significant total cholesterol and LDL improvements only among surgical patients with significant weight reduction (≥5% TW). Both medications were not associated with glycemic improvements among non-surgical and surgical groups. Phentermine had slightly more side effects but was less expensive. Conclusions: Among both patient groups, phentermine was more effective in achieving weight loss. Lorcaserin showed dyslipidemia improvements only among surgical patients who achieved significant weight reduction. Anti-obesity medications as part of weight management programs can result in weight loss among non-surgical and surgical patients, or halt weight regain among surgical patients. This is the first study to evaluate the effectiveness and safety of two anti-obesity medications (lorcaserin vs. phentermine) among two distinct obese patient groups, non-surgical and surgical patients.

    Assessment of PULP score in predicting 30-day perforated duodenal ulcer morbidity, and comparison of its performance with Boey and ASA, a retrospective study2019Inngår i: Annals of Medicine and Surgery, ISSN 2049-0801, Vol. 42, s. 23-28Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: /aim: Scores commonly employed to risk stratify perforated peptic ulcer patients include ASA (American Society of Anesthesiologists), Boey and peptic ulcer perforation score (PULP). However, few studies assessed and compared the accuracy indices of these three scores in predicting post PPU repair 30-day morbidity. We assessed accuracy indices of PULP, and compared them to Boey and ASA in predicting post perforated duodenal (PDU) ulcer repair 30-day morbidity. Methods: Retrospective chart review of all PDU patients (perforated duodenal ulcers only) at the largest two hospitals in Qatar (N = 152). Data included demographic, clinical, laboratory, operative, and post repair 30-day morbidity. Area under the Curve (AUC), sensitivity and specificity were computed for each of the 3 scores. Multivariate logistic regression assessed the accuracy indices of each score. Results: All patients were males (M age 37.41 years). Post PDU repair 30-day morbidity was 10.5% (16 morbidities). Older age, higher ASA (≥3), Boey (≥1) or PULP (≥8) scores, shock on admission and preoperative comorbidities; and conversely, lower hemoglobin and albumin were all positively significantly associated with higher post PDU 30-day morbidity. PULP displayed the largest AUC (72%), and was the only score to significantly predict 30-day morbidity. The current study is the first to report the sensitivity and specificity of these three scores for post PDU repair 30-day morbidity; and first to assess accuracy indices for PULP in predicting post PDU repair 30-day morbidity. Conclusion: PULP score had the largest AUC and was the only score to significantly predict post PDU repair 30-day morbidity. © 2019 The Author(s)

    Laparoscopic hydrocelectomy of the canal of Nuck in adult female: Case report and literature review2020Inngår i: International journal of surgery case reports, ISSN 2210-2612, E-ISSN 2210-2612, Vol. 66, s. 338-341, artikkel-id S2210-2612(19)30674-1Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    INTRODUCTION: Among adult females, Hydrocele of Canal of Nuck (HCN) is a very rare condition. The majority of the reported cases of HCN were not conclusively diagnosed until surgery was performed on a suspected inguinal hernia. To the best of our knowledge, this is the first case of laparoscopically operated HCN in adult female in Middle East and North Africa Region, and the fourth such case worldwide.

    PRESENTATION OF CASE: A 36-year-old female presented with a painful small swelling in the right groin of 3 months duration. The swelling extended to the right labia majora while standing, and disappeared when the patient was in prone position. There was no lymph node enlargement, no other masses in the abdomen, and no swelling in the contralateral side. Ultrasonography was undertaken and the patient was admitted electively for laparoscopic exploration and repair of non-complicated right inguinal hernia. She was known to have dyslipidemia on medications. Further history and physical examination were unremarkable. Intraoperatively it was diagnosed to be right-sided HCN which was excised and repaired by mesh fixation using transabdominal preperitoneal (TAPP) approach. Her follow up course was unremarkable.

    CONCLUSIONS: This case expands the clinical and intraoperative potential differential diagnosis of adult female groin masses. Surgeons should consider such cases when they observe such swellings intraoperatively. Laparoscopic TAPP approach in such cases is a superior diagnostic and treatment modality.

    First sliding Amyand hernia harbouring appendicular schistosomiasis: Case report2019Inngår i: International journal of surgery case reports, ISSN 2210-2612, E-ISSN 2210-2612, Vol. 63, s. 143-146Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: Amyand's hernia (AH) is rare, schistosomiasis of the appendix is very uncommon, and both conditions coexisting together is an extremely rare event. Pre-operative diagnosis of each of the two conditions is usually difficult. To the best of our knowledge, the current paper is first to report both these two conditions in coexistence. Presentation of case: A 31-year old man who had no comorbidities was admitted electively as a day case of non-complicated right indirect inguinal hernia. Further history and physical examination were unremarkable. Intraoperatively the patient was found to have right sliding AH with appendicular schistosomiasis (AS). The patient underwent Lichtenstein repair of the hernia with appendectomy. On follow up he was referred to infectious disease clinic, and the post-operative course was uneventful. Conclusions: Intraoperative identification of non-typical hernia sac before its opening should alert the surgeon to the possibility of sliding hernia and the presence of an organ as a part of the sac. Rare causes of appendicular masses like schistosomiasis granuloma should be considered in endemic areas or immigrants from these areas, despite the difficulty of preoperative diagnosis. Management should follow general guidelines of appendectomy, hernia repair and dealing with the associated pathology if present.
