RESUMEN
Background: This study represents a prospective analysis of a series of laparoscopic ultra low anterior resection (ULAR) done at a laparoscopic surgical center to assess the surgical outcome, oncological efficacy, and quality of life after surgery. Methods: Over a period of 6 years (2013-2018), 43 patients aged between 40 and 68 years, with very low rectal cancers (3-6 cm from the anal verge), within T3N1M0 stage, assessed by positron emission tomography-computed tomography and pelvic magnetic resonance imaging, underwent neoadjuvant chemoradiotherapy (nCRT) followed by laparoscopic ULAR and simultaneous diversion ileostomy. Results: The overall complication rate was low and there was an overall leak rate of 9.3% with a radiological leak (Grade A) in 3 of the 43 patients (7%), but only 1 (2.3%) patient required a local lavage and a resuturing for secondary hemorrhage. Recurrence was seen in 2/43 (4.7%), one of whom had a conversion to abdominoperineal resection. The other had distant metastasis and refused further treatment. The functional outcome is assessed in 41 (95.3%) patients by low anterior resection syndrome (LARS) score and a reasonable quality of life with major LARS was seen in only 7.3% of the patients at a follow-up ranging from 1 to 6 years. Conclusion: The nCRT followed by laparoscopic ULAR is a feasible option for operable very low rectal cancers and is associated with minimal postoperative events, a low local recurrence and less incidence of LARS.

ABSTRACT Minimally invasive procedure for hemorrhoids is one of the commonest new wave operations done for prolapsed hemorrhoids. The diameter of the stapled tissue is critical in this operation, and an increase in the same could include more tissue in the anvil, with disastrous results. This is a case report of a post minimally invasive procedure for hemorrhoids bleed, which was refractory to two local oversewing attempts. When the bleeding was massive, an angiogram was obtained. This revealed a pseudo aneurysm of the left superior haemorrhoidal artery, which was embolized, stopping the bleed. The stapler dimensions were studied and the possible cause of the event was arrived at. The specific stapler used had a diameter of 2 mm more than the regular Medtronic and Ethicon staplers, possibly including more of the rectal wall, and the superior haemorrhoidal artery as well. This case report documents a rare and potentially fatal complication of a simple procedure.
RESUMO O procedimento minimamente invasivo para as hemorroidas (PMIH) é uma das novas operações mais comuns para ao tratamento de hemorroidas prolapsadas. O diâmetro do tecido grampeado é crítico nessa operação; um aumento nesse diâmetro poderia colocar mais tecido na bigorna do grampeador, com resultados desastrosos. Este relato de caso descreve o desfecho de uma hemorragia após PMIH, refratária a duas tentativas locais de sobressutura. Um angiograma foi realizado quando a hemorragia foi considerada intensa. O exame revelou um pseudoaneurisma da artéria hemorroidária superior esquerda, que foi embolizada, interrompendo o sangramento. As dimensões do grampeador foram estudadas e descobriu-se a possível causa do evento. O grampeador específico usado tinha um diâmetro 2 mm maior do que os grampeadores regulares da Medtronic e da Ethicon e possivelmente captou uma área maior da parede retal e a artéria hemorroidária superior. Este relato de caso documenta uma complicação rara e potencialmente fatal de um procedimento simples.
