'Start to finish trans-institutional transdisciplinary care': a novel approach improves colorectal surgical results in frail elderly patients.

AIM: The frail elderly surgical patient is at increased risk of morbidity after major surgery. A transdisciplinary Geriatric Surgery Service (GSS) has been shown to produce consistently positive results in our institution. A trans-institutional transdisciplinary Start to Finish (STF) programme was initiated incorporating seamless prehabilitation and rehabilitation to enhance the outcome further. METHOD: Patients who underwent major colorectal resection in Khoo Teck Puat Hospital and were managed under the GSS from January 2007 to December 2014 were included in this prospective study. The STF programme was initiated from January 2012. The surgical outcome of patients managed under the GSS before the initiation of STF was compared with that after its implementation. RESULTS: There were 57 patients after the initiation of the STF programme compared with 60 patients managed before STF. There were 26.4% and 25% of frail patients in the STF group compared with the non-STF group (P = 0.874). The mean length of hospital stay was significantly shorter in the STF group (8.4 days vs 11.0 days, P = 0.029). Functional recovery in patients available for follow-up at 6 weeks showed 100% (46/46) recovery in the elective STF group who received prehabilitation and 95.7% (45/47) in the elective non-STF group who did not (P = 0.157). There were no significant differences in a Clavien-Dindo complication score of Grade 3 or more and 30-day mortality between the two groups. CONCLUSION: Through a trans-institutional transdisciplinary approach, we managed to achieve a significantly shorter hospital stay in frail patients having colorectal surgery. All elective patients who received prehabilitation achieved full functional recovery.

Obturator hernia: diagnosis and treatment in the modern era.

INTRODUCTION: Obturator hernia is a rare variety of abdominal hernia that nonetheless is a significant cause of morbidity and mortality, especially in the elderly age group. This article aimed to review the diagnosis and management of obturator hernia by describing the anatomy, clinical presentation, predisposing factors, diagnostic modalities and management in the modern era. METHODS: We managed six cases of obturator hernia between 2003 and 2006. Five out of six cases were diagnosed by a preoperative computed tomography (CT) and the sixth case was diagnosed by ultrasonography. All except one were managed by an exploratory laparotomy and repair of the hernia, and one was treated with laparoscopic repair. RESULTS: Correct preoperative diagnosis was made in five out of five (100 percent) patients by clinical signs and CT of the abdomen and pelvis, and the sixth patient was operated on the basis of an ultrasonographical diagnosis and strong clinical suspicion. CONCLUSION: We conclude that the rapid evaluation by CT of the abdomen and pelvis and surgical intervention are possible, thereby reducing the morbidity and mortality of patients with obturator hernia. An algorithm for the management of obturator hernia is proposed.

Ectopic enterogenous cyst.

Enterogenous cyst is a rare congenital lesion presumably of endodermal derivation. It is usually located in the medistinum, the abdominal cavity, skull or within the spinal canal. To our knowledge, it has not been reported in the subcutaneous tissue. We report the first case of ectopic (left scapular region) subcutaneous enterogenous cyst in a 46-year-old man, who presented with a lump over the left scapular region of several years' duration. Clinical diagnosis of lipoma was made. The final histological diagnosis was enterogenous cyst. Enterogenous cysts at ectopic locations should be kept in mind and studied further especially with respect to their development. A better understanding of the embryology, histopathology and genetics of ectopic enterogenous cyst is desired.

Congenital diaphragmatic eventration in an adult: a diagnostic dilemma.

Eventration of the diaphragm is a rare condition where the muscle is permanently elevated, but retains its continuity and attachments to the costal margins. It is seldom symptomatic and often requires no treatment, but may be confused with a traumatic rupture of the diaphragm. We present a 51-year-old man with previously-undiagnosed congenital eventration, mimicking traumatic rupture of the diaphragm. The role of clinical examination, imaging and diagnostic laparoscopy to differentiate between eventration and traumatic rupture of the diaphragm are discussed.
