This study highlights the need for caution when drilling the posterior humeral cortex during biceps tenodesis, particularly during drilling at the superior insertion of PM as this is the location that poses the highest risk to the axillary nerve. To our knowledge, this is the first cadaveric study to radiologically assess the proximity of the axillary nerve to the positions of biceps tenodesis. Surgeons should therefore be cautious when performing bicortical drilling for biceps tenodesis, and a supero-lateral drill trajectory would pose a smaller risk to the axillary nerve.

Perirectal epidermoid cysts are congenital cysts originating from the ectodermal germ cell layer of the hind gut. Their presenting symptoms are most often nonspecific and distinguishing them from other presacral developmental cysts often present a diagnostic and therapeutic dilemma. We present a 58-year-old woman who presented with chronic dyschezia and hematochezia of a few days duration and no prior colonoscopies. Initial blood work and tumor markers were unremarkable. Pelvic magnetic resonance imaging (MRI) showed a 7.5 cm × 5 cm × 6 cm homogenous bi-lobed cystic mass in the pelvis adherent to the left lateral wall of the rectum and posteriorly to the sacrum with a displacement of the rectum anteriorly and to the right. There was no pelvic sidewall adenopathy or free fluid in the pelvis. Preoperative colonoscopy showed rectal compression with no rectal involvement of the mass. The cyst was successfully resected posteriorly via the trans-sacrococcygeal approach. An intraoperative proctosigmoidoscopy confirmed an intact rectum. The patient remains recurrence-free 1 year postsurgical resection.

Purpose There is no consensus on quality of life (QOL) in patients with acromegaly requiring medical treatment after surgery compared with those achieving remission by surgery alone. Methods QuaLAT is a cross-sectional study comparing QOL in surgery-only treated acromegaly patients versus those requiring medical treatment post-surgery. Patients attending clinics were identified and divided into—Group 1: patients who had surgery only and were in biochemical remission, Group 2: all patients on medical treatment post-surgery, Group 3: patients from Group 2 with biochemical control. Participants were asked to fill three questionnaires; Acromegaly Quality of Life Questionnaire (ACROQOL), 36-Item Short Form Survey (SF36), and Fatigue Severity Scale (FSS). Results There were 32 patients in Group 1 and 25 in Group 2. There was no difference in QOL scores between groups 1 and 2, as measured by ACROQOL (mean difference [MD] = − 2.5, 95% CI − 16.6 to 11.6; p = 0.72), SF36v2 [Physical component score (PCS) MD = − 4.9, 95% CI − 10.9 to 1.2; p = 0.12; mental component score MD = − 3.0, 95% CI − 10.5 to 4.4; p = 0.44], or FSS (MD = − 0.004, 95% CI − 1.14 to 1.33; p = 0.1). Comparison between groups 1 and 3 however showed that PCS (and 3 subdomains) was significantly better in group 3 (MD = − 8.3, 95% CI − 14.8 to -1.8; p = 0.01). All three QOL scores were lower when compared with healthy controls. Conclusions Medical treatment not only achieves a QOL comparable to surgery, it may also be associated with better QOL in physical subdomains. When compared with healthy controls, QOL remains worse in treated acromegaly patients compared to controls.

Background Rupture of the pectoralis major (PM) tendon is a rare but severe injury. Several techniques have been described for PM fixation, including a transosseus technique, placing cortical buttons at the superior, middle and inferior PM tendon insertion points. The present cadaveric study investigates the proximity of the posterior branch of the axillary nerve to the drill positions for transosseus PM tendon repair. Methods Twelve cadaveric shoulders were used. The axillary nerve was marked during a preparatory dissection. Drills were passed through the humerus at the superior, middle and inferior insertions of the PM tendon and the drill bits were left in situ. The distance between these and each axillary nerve was measured using computed tomography. Results The superior drill position was in closest proximity to the axillary nerve (three-dimensional distance range 0-18.01 mm, mean 10.74 mm, 95% confidence interval 7.24 mm to 14.24 mm). The middle PM insertion point was also very close to the nerve. Conclusions Caution should be used when performing bicortical drilling of the humerus, especially when drilling at the superior border of the PM insertion. We describe 'safe' and 'danger' zones for the positioning of cortical buttons through the humerus reflecting the risk posed to the axillary nerve.

Background: Quality of life (QOL) in acromegaly has been a subject of interest in several published studies; however, there is no consensus on how QOL in patients who require medical treatment after surgery compares with those who achieve remission by surgery only. Aim: Quality of life after acromegaly treatment (QuaLAT) is a case-control questionnaire-based study with the aim to compare the QOL in those who were treated with surgery only with those who required medical treatment after surgery at a single tertiary centre for acromegaly. Methods: Patients with acromegaly attending endocrinology clinics were identified via our database. These were matched on the duration of disease into those who underwent surgery and went into disease remission biochemically (Group 1), and those who did not achieve biochemical remission after surgery and therefore required further medical treatment to control the disease (Group 2). Participants were then asked to fill three questionnaires to measure their QOL; Acromegaly Quality of Life Questionnaire (ACROQOL), and two generic questionnaires; 36-Item Short Form Survey (SF36) v2, and Fatigue Severity Scale (FSS). Results: 20 patients from each group participated in the study. The mean±SD duration of acromegaly (years) was similar in the two groups (9.8±6.9 vs 9.7±6.9 p=0.653). The majority of patients in the medical group were on somatostatin analogues, either alone or in combination (n=14), with four and two patients on cabergoline and pegvisomant alone respectively. There was no difference in QOL scores between groups 1 & 2, as measured by ACROQOL (mean score±SD 54.4±24.8 vs 55.3±26.1 p=0.765), SF36v2 (Physical component score 40.1± 11.1 vs 45.6±12.0 p=0.235; mental component score 41.7±13.0 vs 43.1±16.4 p=0.601), or FSS (mean score±SD 4.4±2.2 vs 4.5±2.0 p=0.985) questionnaires. There was no difference in ages between both groups and there were 75% females in group 1 and 45% in group 2. When compared with healthy controls as reported in the published literature, all three QOL scores were lower in our cohort [1-3]. Conclusions: Medical treatment achieves similar QOL to surgically treated acromegaly patients in remission in the long term. When compared with healthy controls, QOL remains worse in treated acromegaly patients. References:1.
