Minimum energy laser pilonidotomy (MELPi): a multicenter study of a novel method in pilonidal disease.

Laser surgery, a minimally invasive procedure for the definitive approach to pilonidal disease (PD), has been frequently studied in recent years. This study aims to describe a new pilonidotomy method using minimal laser energy and evaluate its initial results. This is a retrospective multicenter study. We included 47 consecutive patients who underwent 50 "minimal energy pilonidotomies (MELPi)" between 2019 and 2023 in four centers in Brazil. Age, BMI, gender, smoking, diabetes, Guner classification, duration of illness, energy, hospitalization time, complications, recurrence, wound closure, pain, and return to activities were analyzed. The median age was 27; 61.7% were men, and 38.3% were women. The median BMI was 25.7. Smoking was evident in 14.9%, and diabetes in 2.1%. The average duration of the disease was 3 years. Most operations (36%) were performed on stage R disease. The median hospitalization time was 6 h, and the median healing time was 15 days. The average energy used in procedures was 433 J. The median postoperative pain was 2. Secretion occurred in 14% on the 60th day. Complications (cellulitis) occurred in 4% of cases. The median time to return to work was 7 days. The average following time was 12 months; recurrence occurred in 5 (10%)-in 3 patients, a second MELPi procedure was performed and was effective. MELPi shows promising initial results: low pain, low complication rates, and a fast activity return. It is a good option in recidivate cases and can be done more than once if necessary.

Enterocutaneous fistula due to a Richter's hernia after a Tenckhoff catheter removal.

Richter's hernia is a rare type of hernia that occurs when the antimesenteric intestinal wall protrudes through a defect in the abdominal fascia leading to ischaemia, gangrene, bowel perforation and enterocutaneous fistulae. In this article, we describe a rare case of enterocutaneous fistula due to a Richter's hernia after a Tenckhoff catheter removal. This type of complication has not been previously reported in the literature. An 82-year-old man presented with a 1-day history of enteric content at the Tenckhoff catheter insertion site. Seven weeks earlier, the catheter was removed due to peritonitis. Removal was performed using open technique, and the fascia was not closed. Computed tomography revealed a small incarcerated hernia and subcutaneous fluid collection at the previous catheter insertion site. He underwent laparoscopy, which showed a Richter's hernia with perforation of the ileum causing an enterocutaneous fistula. A laparoscopic enterectomy was performed using a primary mechanical anastomosis. The hernia was repaired by primary suture without a mesh because of wound enteral contamination and the small size of the hernia. Richter's hernia has a misleading clinical presentation and contributes to high rates of morbidity and mortality. A secure myofascial closure during catheter removal may reduce the chances of this complication.

LAPAROSCOPIC PERITONEAL DIALYSIS CATHETER PLACEMENT WITH RECTUS SHEATH TUNNELING: A ONE-PORT SIMPLIFIED TECHNIQUE.

BACKGROUND: The success of peritoneal dialysis depends on the proper placement and functional longevity of the dialysis catheter. Laparoscopic implantation of a catheter through a rectus sheath tunneling can minimize the risks of catheter failure. AIMS: This study aims to describe one-port simplified technique for laparoscopic placement of a peritoneal dialysis catheter with rectus sheath tunneling. METHODS: The simplified laparoscopic insertion of a Tenckhoff catheter with rectus sheath tunneling was performed in 16 patients with chronic renal failure. RESULTS: During the follow-up period, no major complications occurred. Three patients were excluded. One was referred to the renal transplant some weeks after implantation, and one died for other reasons during the follow-up. Another patient needed adhesiolysis due to previous surgery, so an additional port was necessary. The other 13 catheters worked properly, and no postoperative hemorrhage, early leaks, hernia, or catheter migration occurred. One patient had a tunnel infection 11 months after the implant. No peritonitis was observed during the follow-up. CONCLUSIONS: The technique is simple, reproducible, and safe, with good results in catheter function, few complications, and a high catheter survival rate. It does not require a special device or trocar and avoids excessive port sites.

RESUMO - RACIONAL: O sucesso da diálise peritoneal depende da implantação adequada e da longevidade funcional do cateter. O implante laparoscópico através da tunelização na bainha do reto abdominal minimiza os riscos de disfunção do cateter. OBJETIVOS: Descrever técnica simplificada com portal único para o implante laparoscópico de cateter de diálise peritoneal com tunelização na bainha do reto abdominal. MÉTODOS: Utilizou-se inserção laparoscópica de cateter de Tenckhoff com tunelização da bainha do reto em 16 pacientes com insuficiência renal crônica. RESULTADOS: Durante o período de acompanhamento não ocorreram complicações relacionadas ao procedimento. Três pacientes foram excluídos: um foi encaminhado para transplante renal algumas semanas após o implante e outro faleceu por outro motivo durante o acompanhamento. Um terceiro necessitou de lise de aderências devido à operação anterior, portanto foi necessário um portal adicional. Os outros 13 pacientes apresentaram bom funcionamento do cateter. Não houve hemorragia pós-operatória, vazamentos, hérnia ou migração do cateter. Um paciente teve infecção no túnel subcutâneo 11 meses após o implante. Não foi observada peritonite durante o período de acompanhamento. CONCLUSÕES: A técnica é simples, reprodutível, segura, com bons resultados de funcionalidade, poucas complicações e alta taxa de sobrevida do cateter. Ela não requer trocarte especial e evita o uso excessivo de portais.
