Outcomes of revisional surgery options after inadequate sleeve gastrectomy: A comprehensive network meta-analysis.

BACKGROUND: Despite the success of sleeve gastrectomy (SG) in of weight loss and treatment of the medical problems associated with obesity, some concerns have arisen about the need for revisional surgeries after SG in some patients. This study aimed to present an updated and comprehensive comparison among the presently available revisional surgeries employed explicitly in cases of inadequate outcomes after SG, which is the most frequently performed bariatric surgery in contemporary practice. METHODS: This network meta-analysis included studies that compared the outcomes of different revisional bariatric procedures after an inadequate outcome of SG. RESULTS: Searching across the electronic databases yielded 31 eligible articles. Re-SG was associated with the highest rate of significant complications. Patients treated with single anastomosis duodenal-ileal bypass (SADI) had a significantly higher percentage of total weight loss (%TWL) than those treated with one anastomosis gastric bypass (OAGB) and Roux-en-Y gastric bypass (RYGB). The percentage of excess weight loss (%EWL) at the end of the follow-up period was significantly higher in patients in the SADI group compared to those in the RYGB group and the OAGB, and re-SG exhibited the least values compared to SADI, biliopancreatic diversion with duodenal switch (BPD/DS), and OAGB. Significantly lower rates of reflux worsening/de novo development were observed in the SADI group compared to the OAGB group and the re-SG group, which showed significantly higher rates than SADI and RYGB. CONCLUSION: Our comprehensive network meta-analysis highlights SADI as a promising revisional option post-SG, demonstrating superior weight loss outcomes, lower significant complication rates, and a favorable impact on reflux compared to other procedures. While acknowledging the limitations of our study, these findings support the potential efficacy of SADI in addressing the challenges of inadequate weight loss after sleeve gastrectomy.

Small bowel lipoma and intussusception: a case report.

Intussusception is defined as the telescoping of bowel into itself. Intussusception is the leading cause of bowel obstruction in children, but it is rare in adults [1, 2]. It has a pathological intramural or extramural lead point. In adults, it accounts for 1%-5% of cases of bowel obstruction [3, 4]. Unlike presentation in the paediatric population of cramping abdominal pain, bloody mucus, and palpable mass in right iliac fossa, presentation in adults can be more varied and non-specific [1, 4]. Hence, diagnosis of small bowel intussusception (SBI) can be challenging, requiring a higher degree of clinical suspicion [5]. While cases of paediatric intestinal intussusception are often primary, most adult cases are secondary to structural lesions [5]. This case is of a 57-year-old lady who presented with SBI secondary to a small bowel lipoma (SBL), reflecting the importance of considering SBL as a differential in the causes of SBI.

Postoperative pancreatic fistula after pancreaticogastrostomy versus pancreatojejunostomy after pancreatic resection, a comparative systematic review and meta-analysis.

BACKGROUND: In patients undergoing pancreaticoduodenectomy (PD), there has been some evidence favoring pancreaticogastrostomy (PG) over pancreatojejunostomy (PJ) in the occurrence of postoperative pancreatic fistulas (POPF) and considering PG as a safer anastomotic technique. However, other publications revealed comparable incidences of POPF attributed to both techniques. The current work attempts to reach a more consolidated conclusion about such an issue. METHODS: This is a systematic review and meta-analysis that analyzed the studies comparing PG and PJ during PD in terms of the rate of POPF occurrence. Studies were obtained by searching the Scopus, PubMed Central, and Cochrane Central Register of Controlled Trials databases. RESULTS: 35 articles published between 1995 and 2022 presented data from 14,666 patients; 4547 underwent PG and 10,119 underwent PJ. Statistically significant lower rates of POPF (p = 0.044) and clinically relevant CR-POPF (p = 0.043) were shown in the PG group. The post-pancreatectomy hemorrhage (PPH) was significantly higher in the PG group, while no significant difference was found between the two groups in the clinically significant PPH. No statistically significant differences were found regarding the amount of intraoperative blood loss, length of hospital stay, DGE, overall morbidity rates, reoperation rates, or mortality rates. The percentage of male sex in the PG group and the percentage of soft pancreas in the PJ group seem to influence the odds ratio of CR-POPF (p = 0.076 and 0.074, respectively). CONCLUSION: The present study emphasizes the superiority of PG over PJ regarding CR-POPF rates. Higher rates of postoperative hemorrhage were associated with PG. Yet, the clinically significant hemorrhage rate was comparable between the two groups.
