Improving quality of breast conservative surgery for lower quadrants cancer in small and medium sized breasts: Crescent technique versus J mammoplasty.

Background: For medium/small size breast, breast conserving surgery (BCS) is usually associated to poor cosmetic results. The objective of the study is to evaluate oncological safety and cosmetic results comparing the "Crescent" and the "J" mammoplasty technique and to develop an algorithm for the treatment of breast cancer located in lower quadrants in medium/small breast. Methods: We retrospectively analysed all consecutive patients who underwent a "J" mammoplasty or a "Crescent" technique at AUSL IRCCS Reggio Emilia between 2016 and 2021. Fifty-eight patients were enrolled, the first group including 29 "Crescent" technique procedures and the second one including 29 patients who underwent the "J" mammoplasty technique. Oncological safety and surgical minor and major complications were evaluated. Aesthetic results were evaluated by two senior breast surgeons, independently, at least 6 months after radiotherapy (RT). Results: At follow-up of 36 months, no recurrences and no major complications were observed in both groups. Minor complications were observed in two (6.9%) "J" group cases and in six (20.7%) "Crescent" ones (P<0.05). The 96.6% of "Crescent" and the 73.5% of "J" cases were judged excellent/good. One (3.4%) "Crescent" was judged fair versus six (20.7%) "J" mammoplasty. Two (6.9%) "J" cases were judged poor, requiring ipsilateral re-operation. Conclusions: When a favourable ratio between tumor size and breast volume is present, BCS can be performed for tumors located in the lower quadrants. Evaluating patients' anthropometric characteristics, skin involvement and tumor features is the key to select the right technique and to obtain both great cosmetic result and low rate of complications.

A Pure Autologous Dermal Graft and Dermal Flap Pocket in Prepectoral Implant Reconstruction After Skin-Reducing Mastectomy: A One-Stage Autologous Reconstruction Alternative to Acellular Dermal Matrices.

Skin-reducing mastectomy (SRM) with subpectoral implant positioning represents a consolidated, oncologically safe and cosmetically effective method for the immediate reconstruction of large and ptotic breasts. Acellular dermal matrix (ADM) has been proposed as a substitute for the pectoralis major muscle in this surgical approach; this technique led to a progressive evolution toward prepectoral reconstructions even in skin-reducing mastectomies. Obese patients with macromastia who are typical candidates for SRM with ADM are at increased risk of complications associated with ADMs. Therefore, we avoided ADMs and developed a novel autologous technique for immediate breast reconstruction in large and ptotic breasts eligible for SRM. Specifically, an autologous dermal graft is harvested from contralateral healthy breast reduction to cover the upper pole of the prepectoral implant.Level of Evidence IV This journal requires that authors assign a level of evidence to each article.

Duplication of the transverse colon in an adult: case report and review.

Tubular duplication of the colon is very rare especially in adulthood, because it is frequently symptomatic earlier in newborn life, so only few cases are reported in literature. Several theories are proposed to explain the onset and the evolution of gut malformations as the aberrant lumen recanalization or the diverticular theory, the alteration of the lateral closure of the embryonal disk or finally the dorsal protrusion of the yolk-sac for herniation or adhesion to the ectoderm for an abnormality of the longitudinal line, but none clarifies the exact genesis of duplication. We present a case of "Y-shaped" tubular duplication of the transverse colon in a 21-year-old adult, with a history of chronic pain and constipation, referred to our department for abdominal pain with retrosternal irradiation, treated with the resection of the aberrant bowel.
