Treatment algorithm for anal fissure. Consensus document of the Spanish Association of Coloproctology and the Coloproctology Division of the Spanish Association of Surgeons. / Tratamiento de la fisura anal: algoritmo de actuación. Documento de consenso de la Asociación Española de Coloproctología y la Sección de Coloproctología de la Asociación Española de Cirujanos.

The Spanish Association of Coloproctology and the Coloproctology Division of the Spanish Association of Surgeons propose this consensus document with a treatment algorithm for anal fissure that could be used for decision making. Non-surgical therapy and surgical treatment of anal fissure are explained, and the recommended algorithm is provided. The methodology used was: creation of a group of experts; search in PubMed, MEDLINE and the Cochrane Library for publications from the last 10 years about anal fissure; presentation at the 21st National Meeting of the Spanish Association of Coloproctology Foundation 2017 with voting for/against each conclusion by the attendees and review by the scientific committee of the Spanish Association of Coloproctology.

Postoperative morbidity of biliopancreatic diversion depending on common limb length.

BACKGROUND: Laparoscopic gastric bypass, currently the most popular surgical method for bariatric therapy, have proved to be effective in weight loss, but some matters regarding its long-term efficacy for super-obese patients (BMI >50 kg/m2) have arisen. Biliopancreatic diversion (BPD) is a complex technique that has shown good results in the treatment of the super-obese patient. We analyze our >5 years results, evaluating weight loss, morbidity and mortality of this operation, depending on the length of the common and alimentary limbs. METHODS: We studied two series of patients: 150 patients with BPD of Scopinaro (50-200 cm) and 70 patients with modified BPD (75-225 cm). The results have been analyzed in terms of weight loss, co-morbidity improvement, and postoperative morbidity using BAROS. RESULTS: Range of follow-up is 1-12 years. Weight loss was slightly higher for the Scopinaro group than for the Modified group but with no significant difference. There was more prevalence of malnutrition and of iron deficiency in the Scopinaro group (16% and 60%) than in the modified group (2% and 40%), with similar postoperative morbidities. CONCLUSION: The modified BPD method (75-225 cm) shows long-term effectiveness in weight loss and comorbidity improvement for super-obesity. Proteins, vitamins and oligoelement deficits appear distant in time, and thus it is necessary to maintain strict followup of these patients and supplement against deficiencies for the rest of their lives.

Current Controversies in Transanal Surgery for Rectal Cancer.

Local surgery for rectal tumors has been traditionally limited due to technical issues for lower risk lesions. In the 1980s, Buess described the transanal endoscopic microsurgery (TEM) technique that enabled excision of lesions that were larger and in a higher location. TEM in a short time became the gold standard for the excision of large adenomas and early rectal carcinomas. Since the advent of TEM, and due to advances in minimal invasive technology, new devices and procedures have come to the surgical armamentarium, in many cases with only very slight differences between them. However, local surgery for rectal cancer still remains a challenge. An overview of the current status of minimal transanal invasive techniques is presented here and sheds some light on the controversies that the local management of rectal cancer still raises.
