Purpose Many revisional procedures are available for unsuccessful laparoscopic sleeve gastrectomy (LSG) in patients with complications or weight recidivism. Single anastomosis duodeno-ileal bypass (SADI-S) and one anastomosis gastric bypass (OAGB-MGB) are two revisional procedures to address the problem of weight recidivism. We aimed to evaluate the efficacy and outcomes of the 2 revisional approaches (SADI-S vs. OAGB-MGB). Materials and Methods A retrospective analysis of prospectively collected database of patients who underwent SADI-S or OAGB-MGB as a revisional procedure for weight recidivism after primary LSG with a minimum 1-year follow-up. Weight loss, comorbidities, nutritional deficiencies, complications, and outcomes were compared in the 2 procedures. Results Ninety-one patients were included in the study (42 SADI-S and 49 OAGB-MGB). There was a significant weight loss (total weight loss percentage, TWL%) at 1-year follow-up observed for SADI-S when compared to OAGB-MGB (23.7 ± 5.7 vs. 18.7 ± 8.5, p = 0.02). However, this difference was not statistically significant at 18 months (26.4 ± 7.3 vs. 21.2 ± 11.0, p = 0.25). Remission of comorbidities (diabetes mellitus and hypertension) was comparable. Although OAGB-MGB had higher complication rate than SADI-S, the difference was not statistically significant (p = 0.39). No mortality was reported in the study groups. Conclusion Both SADI-S and OAGB-MGB are effective and safe revisional procedures for weight regain after LSG. The shortterm outcomes are comparable; however, SADI-S is associated with less upper gastrointestinal complications and could be a better option for patients suffering from GERD post-LSG. Moreover, the underlying bile reflux may get worse with OAGB-MGB. However, further prospective larger studies are needed. Keywords Revisional surgery. Sleeve gastrectomy.

BackgroundAppendicular neuroendocrine tumors (NET, Carcinoid tumors) of the appendix are rare and mostly diagnosed incidentally on the post-operative histopathological examination. NET are usually associated with good 5-year survival rates. We aimed to assess our experience for the diagnosis and management of NET over 11 years.MethodIt is a retrospective chart review of all clinically suspected patients with acute appendicitis who underwent emergent appendectomy with intention to treat between January 2004–December 2014, and were clinically followed up until 2016.ResultsDuring the study period, a total of 13641 patients underwent emergency appendectomy, of which 32 were histologically confirmed NET. The mean age of the NET cases was 25.3 ± 7.9 years; 78% were males and all were clinically presented with acute appendicitis. The mean leucocyte was 15 ± 14 × 109 per Liter, and mean tumor size was 4.86 ± 3.18 (ranged 1.5–13) mm. The median length of hospital stay was 4 (2–15) days. One patient had right hemicolectomy; diagnosed with right colonic cancer with NET being an incidental finding as part of histopathological assessment. Another patient required a second stage procedure; he was diagnosed as goblet cell carcinoid with positive margin. None of the patients died 30-day postoperatively and all of them survived on clinical follow-up that ranged between 2 and 13 years.ConclusionCarcinoid tumors of the appendix are rare and typically diagnosed incidentally. Detailed examination of routine appendectomy specimens is the key for diagnosis. Simple appendectomy suffices for tumors <2 cm for adequate clearance. Appendicular carcinoid tumors are associated with good long-term outcomes.
Highlights Pelvic mass causing abdominal pain may appear on imaging as adnexal in origin. Appendicular mucocele can present as an adnexal mass. Appendicular mucocele is challenging to diagnose pre-operatively. Variable scenarios can be encountered with pre-operative diagnosis of adnexal mass. Patients with adnexal mass should be counselled about the possible findings.
Background. The predictive role of platelet to lymphocyte ratio (P/LR) in patients with perforated peptic ulcer (PPU) is not well-studied. We aimed to investigate the association between the P/LR ratio and the hospital length of stay (HLOS) for surgically treated PPU. Method. This is a retrospective observational study for surgically treated adult cases of PPU at Hamad Medical Corporation during the period from January 2012 to August 2017. Patients were categorized into two groups based on their HLOS (<I week vs. >I week). The receiver operating characteristic (ROC) curve was plotted to determine the cutoff value for lymphocyte count, neutrophil to lymphocyte ratio, and P/LR ratio for predicting the prolonged hospitalization. Results. One hundred and fifty-two patients were included in the study. The majority were young males. The mean age was 38.3 ± 12.7 years. Perforated duodenal ulcer (139 patients) exceeded perforated gastric ulcer (13 patients). The HLOS > 1 week was observed in 14.5% of cases. Older age ( p = 0.01 ), higher preoperative WBC ( p = 0.03 ), lower lymphocyte count ( p = 0.01 ), and higher P/LR ratio ( p = 0.005 ) were evident in the HLOS > 1 week group. The optimal cutoff value of P/LR was 311.2 with AUC 0.702 and negative predictive value of 93% for the prediction of prolonged hospitalization. Two patients died with a mean P/LR ratio of 640.8 ± 135.5 vs. 336.6 ± 258.9 in the survivors. Conclusion. High preoperative P/LR value predicts prolonged HLOS in patients with repaired perforated peptic ulcer. Further larger multicenter studies are needed to support the study findings.
Background Appendicular neoplasms are rare, most commonly as carcinoids followed by appendicular mucinous neoplasms (AMN). To date, there remains controversy regarding the best treatment of AMN and factors affecting its prognosis. Method Retrospective chart review of patients operated for appendicular pathology (January 2011–December 2018, follow up to December 2020) at our institution. For all AMN patients, data included pre-operative clinical presentation, and operative/post-operative findings. Results 12454 patients underwent appendectomy, of whom 50 (0.4%) had AMN histopathologically (mean age = 47.2). Most patients had laparoscopic appendectomy as primary surgery. Low grade AMN was the most common subtype (n = 41, 82%), and pseudomyxoma peritonei (PMP) was found in 8 (16%) patients. Based on histopathology and margin involvement, the 50 patients were categorized into 3 prognostic categories of recurrence risk (no risk, 24 patients; low risk, 8; high recurrence risk, 18 patients). Disease-free survival (DFS) was lowest for high recurrence risk group (P < 0.001). Eleven (22%) patients had AMN involving resection margin, of whom 3 had no completion surgery and had no recurrence. Higher tumor markers were associated with lower DFS, however it was not statistically significant. Conclusion AMNs are rare but serious due to the risk of PMP. Laparoscopic approach for AMN may be feasible. Prognostic categories were significantly inversely correlated with recurrence risk; hence useful in predicting prognosis. Contrary to previous proposals, AMNs with acellular mucin at margin or local acellular mucin spillage may not require secondary surgery, especially if the patient is in low recurrence risk group. Tumor markers may predict risk of recurrence.
Highlights Equivocal signs and symptoms along with anatomical position of appendiceal mucinous neoplasm (AMN) makes it difficult to diagnose. Pre-operative, findings like ‘onion skin’ sign on ultrasonography and ‘volcano sign’ on colonoscopy are specific for appendiceal mucocele. Primary AMN is rarely diagnosed before operation and histopathological examination. AMN can mimic ovarian tumors. Consider AMN in the differential diagnosis for any pelvic mass in elderly female patients.
HighlightsAmyand’s hernia is uncommon in females.The initial presentation as an abdominal wall abscess is very rare in the contemporary literature.An index of suspicious, early diagnosing and surgical intervention lead to favorable recovery.The management should follow general guidelines of appendectomy, hernia repair and dealing with the associated pathology if present.
Granulosa cell tumor (GCT) is a unique form of sex cord tumor that is mostly unilateral and of low-grade malignancy. Most GCT recurrence is with pelvic or peritoneal dissemination. Liver metastasis is rarely reported. This study reports a rare case of GCT with liver metastasis nine years post initial presentation. We also discuss surgical intervention, radiological findings, histology, treatment approaches, and review of similar reported cases.
