To evaluate difference in local recurrence, regional (neck) recurrence as well as distant metastases between cases operated with en-block excision of primary cancer and neck nodes versus their separate removal, in squamous cell carcinomas of anterior 2/3 of tongue and floor of the mouth. A total 85 patients of cT1-T4a N0-N2b of carcinoma anterior 2/3 of tongue and floor of mouth were evaluated. Amongst these patients 39 cases of in-continuity en-block neck dissection and 46 cases of discontinuous neck dissection were evaluated for post-operative complications as well as oncological outcome for a follow up period of 3 years. Patient population was similar in both groups with tongue cancers being the commonest site and tobacco being the most common addiction. Primary site hematoma was seen more in the in-continuity en-block neck dissection group with a p-value of 0.0276, which was statistically significant. Post-operative oro-cutaneous fistula occurred more in in-continuity enblock neck dissection as compared to discontinuous neck dissection, but the difference was not statistically significant. Local recurrence rate was significantly more in cases of discontinuous neck dissection (19.565) as compared to in-continuity en-block neck dissection (5.12%) with a p-Value 0.0481. A statistically non-significant but higher loco-regional recurrence was observed in cases of discontinuous neck dissection as compared to cases of in-continuity en-block neck dissection (10.56% vs 2.56). In the present study recurrence-free survival RFS 3 year in cases of en-block in-continuity neck dissection (84.06%) cases as compared to discontinuous neck dissection cases (63.04%) with p Value 0.025698. In-continuity en-block in continuity neck dissection has lower loco-regional recurrence and may impact overall distant metastases. Though early postoperative complications are more in in-continuity en-block in continuity neck dissection as compared to discontinuous neck dissection, most are managed conservatively. Further studies with a larger sample size are needed to evaluate its outcome in a comprehensive manner. © 2021, Association of Otolaryngologists of India.
Octreotide and postoperative pancreatic fistula after pancreaticoduodenectomy: What we know so far- A narrative review
(Wolters Kluwer Medknow Publications, 2023) Mandar Tilak; Mallika Tewari; H.S. Shukla
Postoperative pancreatic fistula (POPF) is the most feared complication following pancreatic resection. Octreotide, a synthetic somatostatin analog, has been widely used by pancreatic surgeons worldwide after pancreatic resections, often as per surgeon's discretion, to prevent POPF especially in cases at high risk of developing POPF. We herein analyze the data available till date of the subject. A PubMed search with keywords 'somatostatin OR octreotide OR somatostatin analogues AND postoperative pancreatic fistula' was made. Further filters were applied in the search 'Clinical Trial, Meta-Analysis, Randomized Controlled Trial, Systematic Review, from 1990 - 2021,' and the 68 results thus obtained were analyzed and included in this narrative review. There is considerable heterogeneity among the studies assessing the role of octreotide in the prevention of POPF making data comparison difficult, and hence results remain inconclusive. Most of the earlier studies used different definitions of POPF and other complications; included patients with varied pancreatic pathologies such as cancer, chronic pancreatitis, and benign lesions; surgical techniques such as pancreaticoduodenectomy, distal pancreatectomy, and other procedures; use of somatostatin and its analogs such as octreotide, lanreotide, pasireotide, and vapreotide; varied surgeon and institutional volume; and so on. Besides, pancreatic surgery is per se a complex surgical procedure and has its own inherent biases related to patient and the pancreas itself affecting the overall outcome. Data indicate favorable role of newer somatostatin analogs, and further studies are urgently needed. The question about the efficacy of prophylactic octreotide to reduce POPF after pancreaticoduodenectomy remains open to debate. © 2023 Copyright:
