RESUMO
BACKGROUND: Gastroesophageal reflux disease (GERD) remains one of the most commonly encountered gastrointestinal disorders. Proton pump inhibitors still show an inadequate effect on about 10% to 40% of the patients. Laparoscopic antireflux surgery is the surgical alternative for managing GERD in patients who are not responding to proton pump inhibitors. AIM OF THE STUDY: This study objected at comparing laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication (LTF) concerning the short-term and long-term outcomes. PATIENTS AND METHODS: This is a systematic review and meta-analysis that evaluated the studies comparing between Nissen fundoplication and LTF for the treatment of GERD. Studies were obtained by searching on the EMBASE, the Cochrane Central Register of Controlled Trials, and PubMed central database. RESULTS: The LTF group showed significantly longer operation time, less postoperative dysphagia and gas bloating, less pressure on the lower esophageal sphincter, and higher Demeester scores. No statistically significant differences were found between the 2 groups in the perioperative complications, the recurrence of GERD, the reoperation rate, the quality of life, or the reoperation rate. CONCLUSION: LTF is favored for the surgical treatment of GERD being of lower postoperative dysphagia and gas bloating rates. These benefits were not at the expense of significantly additional perioperative complications or surgery failure.

This is a systematic review and meta-analysis that assessed the impact of performing OAGB with a 150-cm BPL versus a 200-cm BPL concerning weight loss, comorbidities remission, and adverse nutritional effects. The analysis included studies that compared patients who underwent OAGB with a 150-cm BPL and 200-cm BPL. Eight studies were eligible for this review after searching in the EMBASE, PubMed central database, and Google scholar. The pooled analysis revealed favoring the 200-cm BPL limb length for weight loss, with a highly significant difference in the TWL% (p=0.009). Both groups showed comparable comorbidities remission. Significantly higher ferritin and folate deficiency rates were found in the 200-cm BPL group. Considering a 200-cm BPL when performing OAGB delivers a better weight loss outcome than a 150-cm BPL, which is at the expense of a more severe nutritional deficiency. No significant differences were found regarding the comorbidities' remission.

BACKGROUND: Obesity is a widely prevalent medical and socioeconomic problem. Bariatric surgery is indicated for patients with clinically severe obesity. Reduction of gastric volume is an important factor that contributes to weight loss after laparscopic sleeve gastrectomy (LSG). The impact of the gastric volume on weight after LSG has been studied. AIM OF THE STUDY: This study was designed to assess the gastric volume in patients with obesity prior to LSG and in the normal-weight patients, using three-dimensional multi-detector computer tomography (3D-MDCT), and to evaluate the potential correlation of the gastric volume with body mass index (BMI). PATIENTS AND METHODS: A total of 100 patients were equally enrolled in two groups: one group for patients with obesity scheduled for LSG and another one for normal-weight patients scheduled for non-bariatric surgery. The study patients underwent 3D-MDCT gastric volumetry. RESULTS: The gastric volume ranged from 525 to 1170 mL in patients with obesity and from 312 to 676 mL in the normal-weight group. Statistically significant difference was found between the two groups. Age, weight, and BMI were found to be predictors for the gastric volume in normal-weight patients only. CONCLUSION: MDCT gastric volumetry is a feasible method to assess the stomach volume. Higher volumes were evident in patients with obesity. Age, weight, and BMI are predictors for the gastric volume in normal-weight patients with linear regression equations that could help during the preoperative planning of bariatric surgeries.

BACKGROUND: Despite the widescale success of proton pump inhibitors to reducing the incidence of peptic ulcer disease, perforated peptic ulcer (PPU) remains a significant cause of severe complications and death. The implementation of open or surgical repair of PPU should be guided by reliable guidelines which are based on current systematic evidence. OBJECTIVES: To assess the comparative efficacy and safety of laparoscopic and open repair of PPU. METHODS: A systematic review and meta-analysis was conducted based on retrospective, prospective cohort studies, and randomized clinical trials. Duration of surgery and postoperative complications and death were collected from eligible studies, and the outcomes were pooled using mean differences (MD) or relative risks (RRs) for numerical and binary outcomes, respectively. The estimated variance was expressed as 95% confidence intervals (95% CIs). RESULTS: Forty-five studies were included (8456 patients, 56.08% underwent open repair, 6 prospective studies, 7 randomized clinical trials, and 32 retrospective studies). Compared with open repair, laparoscopic surgeries were associated with longer operative times (MD=8.36, 95% CI, 0.49-16.22), shorter hospital stay (MD=-2.74, 95% CI, -3.70 to-1.79), a higher risk of suture leakage (RR=1.91, 95% CI, 1.04-3.49) and lower risks of mortality (RR=0.57, 95% CI, 0.47-0.70), septic shock (RR=0.69, 95% CI, 0.49-0.98), renal failure (RR=0.38, 95% CI, 0.18-0.79), and wound infection (RR=0.26, 95% CI, 0.19-0.37). CONCLUSION: Laparoscopic repair of PPU showed promising safety outcomes; however, future well-designed randomized studies are warranted to reduce the observed performance bias and possible selection bias in individual studies.
